Abstract
PURPOSE To compare the anatomical and functional outcomes of macular hole (MH)-associated retinal detachment after vitrectomy with the internal limiting membrane (ILM) insertion technique or the inverted ILM flap technique. METHODS In this retrospective observational study, we reviewed the medical records of 49 eyes with MH-associated retinal detachment that underwent vitrectomy with the ILM insertion (26 eyes) or ILM flap (23 eyes) technique. RESULTS The MH closure rate at 12 months was greater in the ILM flap group versus the ILM insertion group (95% vs. 73%, respectively, P = 0.059). The postoperative best-corrected visual acuity (BCVA) at 12 months was significantly better in the ILM flap group (P = 0.014). All eyes (100%) showed an improvement in the BCVA of ≥0.3 logarithm of the minimum angle of resolution (15 Early Treatment Diabetic Retinopathy Study letters) in the ILM flap group versus 20 eyes (77%) in the ILM insertion group (P = 0.026). The preoperative BCVA and the ILM flap technique were significantly correlated with the postoperative BCVA (P = 0.028 and 0.027, respectively) and BCVA improvement (≥0.3 logarithm of the minimum angle of resolution [15 Early Treatment Diabetic Retinopathy Study letters]; P = 0.003 and 0.026, respectively). CONCLUSION The inverted ILM flap technique was more effective in improving the postoperative BCVA in patients with MH-associated retinal detachment when compared with the ILM insertion technique. The preoperative BCVA and the ILM flap technique were independent prognostic factors for visual outcomes in patients with MH-associated retinal detachment.

Abstract
BACKGROUND The efficacy and safety of nivolumab plus cabozantinib as compared with those of sunitinib in the treatment of previously untreated advanced renal-cell carcinoma are not known. METHODS In this phase 3, randomized, open-label trial, we randomly assigned adults with previously untreated clear-cell, advanced renal-cell carcinoma to receive either nivolumab (240 mg every 2 weeks) plus cabozantinib (40 mg once daily) or sunitinib (50 mg once daily for 4 weeks of each 6-week cycle). The primary end point was progression-free survival, as determined by blinded independent central review. Secondary end points included overall survival, objective response as determined by independent review, and safety. Health-related quality of life was an exploratory end point. RESULTS Overall, 651 patients were assigned to receive nivolumab plus cabozantinib (323 patients) or sunitinib (328 patients). At a median follow-up of 18.1 months for overall survival, the median progression-free survival was 16.6 months (95% confidence interval [CI], 12.5 to 24.9) with nivolumab plus cabozantinib and 8.3 months (95% CI, 7.0 to 9.7) with sunitinib (hazard ratio for disease progression or death, 0.51; 95% CI, 0.41 to 0.64; P<0.001). The probability of overall survival at 12 months was 85.7% (95% CI, 81.3 to 89.1) with nivolumab plus cabozantinib and 75.6% (95% CI, 70.5 to 80.0) with sunitinib (hazard ratio for death, 0.60; 98.89% CI, 0.40 to 0.89; P = 0.001). An objective response occurred in 55.7% of the patients receiving nivolumab plus cabozantinib and in 27.1% of those receiving sunitinib (P<0.001). Efficacy benefits with nivolumab plus cabozantinib were consistent across subgroups. Adverse events of any cause of grade 3 or higher occurred in 75.3% of the 320 patients receiving nivolumab plus cabozantinib and in 70.6% of the 320 patients receiving sunitinib. Overall, 19.7% of the patients in the combination group discontinued at least one of the trial drugs owing to adverse events, and 5.6% discontinued both. Patients reported better health-related quality of life with nivolumab plus cabozantinib than with sunitinib. CONCLUSIONS Nivolumab plus cabozantinib had significant benefits over sunitinib with respect to progression-free survival, overall survival, and likelihood of response in patients with previously untreated advanced renal-cell carcinoma.

Current drug metabolism. 2020;(10):818-828
Abstract
OBJECTIVE The aim is to compare atorvastatin versus rosuvastatin on secondary percutaneous coronary intervention (PCI) rate and explore risk factors in coronary heart disease (CHD) patients. METHODS A cohort study with 283 CHD subjects was launched from 2011 to 2015. Cox proportional hazards regression model, Receiver Operating Characteristic (ROC) and nomogram were used to compare the effect of atorvastatin and rosuvastatin on secondary PCI rate and disease risk factors. Even why the two statins had different effects based on gene expression profile analysis has been explored. RESULTS Gene FFA (Freely fatty acid), AST (Aspartate Transaminase) and ALT (Alanine transaminase) showed the statistical difference between the four statin groups (P<0.05). In the AA group (Continuous Atorvastatin usage), albumin was a risk factor (Hazard Ratio (HR):1.076, 95%CI (1.001, 1.162), p<0.05). In the AR group (Start with Atorvastatin usage, then change to Rosuvastatin usage), ApoA was a protective factor (HR:0.004, 95%CI (0.001, 0.665), p<0.05). GLB (Galactosidase Beta) was a risk factor (HR:1.262, 95%CI (1.010, 1.576), p<0.05). In RR group (Continuous Rosuvastatin usage), ApoE was a protective factor (HR:0.943, 95%CI (0.890, 1.000), <0.05). ALT was a risk factor (HR:1.030, 95%CI (1.000, 1.060), p<0.05). CONCLUSION Patients in the RA group had the lowest secondary PCI rate. ALT was a risk factor in the RR group. Gene Gpt (Glutamic Pyruvic Transaminase) encoded for one subtype of ALT had a significantly different expression in different statin groups.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is the leading cause of death among preterm infants born at < 30 weeks' gestation. The incidence of NEC is reduced when infants are fed human milk. However, in many neonatal intensive care units (NICUs), it is standard practice to freeze and/or pasteurize human milk, which deactivates bioactive components that may offer additional protective benefits. Indeed, our pilot study showed that one feed of fresh mother's own milk per day was safe, feasible, and can reduce morbidity in preterm infants. To further evaluate the benefits of fresh human milk in the NICU, a randomized controlled trial is needed. METHODS Our prospective multicenter, double-blinded, randomized, controlled trial will include infants born at < 30 weeks' gestation and admitted to one of 29 tertiary NICUs in China. Infants in the intervention (fresh human milk) group (n = 1549) will receive at least two feeds of fresh human milk (i.e., within 4 h of expression) per day from the time of enrollment until 32 weeks' corrected age or discharge to home. Infants in the control group (n = 1549) will receive previously frozen human milk following the current standard protocols. Following informed consent, enrolled infants will be randomly allocated to the control or fresh human milk groups. The primary outcome is the composite outcome mortality or NEC ≥ stage 2 at 32 weeks' corrected age, and the secondary outcomes are mortality, NEC ≥ stage 2, NEC needing surgery, late-onset sepsis, retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), weight gain, change in weight, increase in length, increase in head circumference, time to full enteral feeds, and finally, the number and type of critical incident reports, including feeding errors. DISCUSSION Our double-blinded, randomized, controlled trial aims to examine whether fresh human milk can improve infant outcomes. The results of this study will impact both Chinese and international medical practice and feeding policy for preterm infants. In addition, data from our study will inform changes in health policy in NICUs across China, such that mothers are encouraged to enter the NICU and express fresh milk for their infants.

Abstract
BACKGROUND Previous studies have investigated the relationship of the triglyceride glucose (TyG) index with the incidence of cardiovascular events. However, to date, there have been no studies comparing the predictive values of fasting plasma glucose (FPG), glycosylated hemoglobin A (HbA1C) and the TyG index for the risk of cardiovascular events. This study aimed to use discordance analysis to evaluate and compare the effectiveness of FPG, HbA1C and the TyG index to predict the risk of cardiovascular events. METHODS Patients diagnosed with acute coronary disease (ACS) undergoing percutaneous coronary intervention (PCI) were enrolled in this study. The TyG index was computed using the following formula: ln [fasting triglycerides (mg/dL) × FPG (mg/dL)/2]. We categorized patients into 4 concordance/discordance groups. Discordance was defined as a TyG index equal to or greater than the median and an FPG or HbA1C less than the median, or vice versa. The primary outcome was the composite of death, nonfatal myocardial infarction, nonfatal stroke and unplanned repeat revascularization. A Cox proportional hazards regression model was performed to estimate the risk of cardiovascular events according to the concordance/discordance groups. Sensitivity analysis was performed on each patient group divided into high or low categories for HbA1C or FPG and were repeated according to diabetes status. RESULTS In total, 9285 patients were included in the final statistical analysis (male: 75.3%, age: 59.9 ± 10.05 years, BMI: 26.2 ± 9.21 kg/m2, diabetes: 43.9% and dyslipidemia: 76.8%). The medians defining concordance/discordance were 6.19 mmol/L for FPG, 6.1% for HbA1C and 8.92 for the TyG index. The TyG index was strongly related to triglycerides and HDL-C (r = 0.881 and -0.323, respectively; both P < 0.001). During the 17.4 ± 2.69 months of follow-up, there were 480 (5.1%) incident cardiovascular events. Among patients with a lower HbA1C or FPG, 15.6% and 16.3%, respectively, had a discordantly high TyG index and a greater risk of cardiovascular events compared with patients with a concordantly low TyG index after full adjustment (HR: 1.92, 95% CI 1.33-2.77; HR: 1.89, 95% CI 1.38-2.59; for HbA1C and FPG, respectively). Repeat risk estimation using high or low categories for FPG or HbA1C and diabetes status confirmed the results. CONCLUSIONS Patients with a discordantly high TyG index had a significantly greater risk of cardiovascular events regardless of diabetes status. The TyG index might be a better predictor of cardiovascular risk than FPG or HbA1C for patients with ACS undergoing PCI. This discordance may support better cardiovascular risk management regardless of diabetes status.

Abstract
BACKGROUND The efficacy and safety of calcipotriol plus betamethasone dipropionate gel for the treatment of scalp psoriasis has previously been demonstrated in a four-week trial in a Chinese population. OBJECTIVE To evaluate the long-term safety and efficacy of two-compound gel in Chinese adult patients with scalp psoriasis. MATERIALS & METHODS A multicentre, prospective, randomized, active-controlled trial was established in which subjects were randomized (at a ratio of 4:1) to receive either two-compound gel once daily or calcipotriol scalp solution twice daily for 28 weeks. Incidence of adverse drug reactions (ADRs) of any type and adverse events (AEs) of concern associated with long-term corticosteroid use on the scalp were evaluated. RESULTS A total of 951 subjects were randomly assigned to receive either two-compound gel (n=760) or calcipotriol scalp solution (n=191). The incidence of ADRs was significantly lower in the two-compound gel group compared with the calcipotriol scalp solution group (11.7 vs. 22.2%, p<0.001). There was no significant difference in treatment-emergent adverse events (TEAEs) associated with long-term topical corticosteroid use on the scalp (1.1% vs. 0%, p=0.369) between the two groups. A statistically significant difference in the percentage of visits with treatment success according to the Subject's Global Assessment was observed (p=0.009); more subjects had visits with 100% treatment success (15.2 vs. 6.3%) and fewer subjects had visits with 0% treatment success (23.7 vs. 30.8%) using two-compound gel compared to calcipotriol scalp solution. CONCLUSION The two-compound gel was well tolerated and effective in the long-term management of scalp psoriasis in Chinese patients.

Abstract
BACKGROUND Exenatide, a glucagon like peptide 1 analog, has been suggested to reduce the cardiovascular disease risk factors, such as body weight, blood pressure and subclinical atherosclerosis in patients with type 2 diabetes mellitus (T2DM). This was the first randomized, open-label, controlled trial to compare the effects of exenatide versus insulin on subclinical atherosclerosis, as assessed by carotid-intima media thickness (CIMT), in patients with T2DM. METHODS A total of 66 patients with T2DM admitted from March 10, 2015 to June 20, 2017 in the Department of Endocrinology, Beijing Hospital were randomized to receive twice-daily exenatide or aspartate 70/30 insulin for 52 weeks. The primary endpoint was change from baseline in CIMT, and secondary endpoints included changes at week 52 from baseline in body weight, glycemic markers, lipid metabolism markers, blood pressure, C-reactive protein, fibrinogen, 8-hydroxydeoxyguanosine, irisin, and brain natriuretic peptide. RESULTS Exenatide more significantly reduced the CIMT from baseline compared with insulin after 52 weeks, with a mean difference of - 0.14 mm (95% interval confidence: - 0.25, - 0.02; P = 0.016). Weight and body mass index were both significantly reduced in the exenatide group over 52 weeks. Exenatide reduced total lipoprotein and low-density lipoprotein cholesterol levels more significantly than insulin at weeks 16 and 40. Correlation analyses showed that CIMT was positively correlated with low-density lipoprotein cholesterol. CONCLUSIONS Twice-daily exenatide could prevent atherosclerosis progression in patients with T2DM over a 52-week treatment period compared with insulin therapy.

Stroke. 2019;(11):3255-3258
Abstract
Background and Purpose- We aimed to examine the relation of baseline plasma zinc with the risk of first stroke and investigate any possible effect modifiers in hypertensive patients. Methods- The study population was drawn from the CSPPT (China Stroke Primary Prevention Trial), using a nested case-control design, including 599 first stroke cases and 599 matched controls. Results- Compared with participants with baseline plasma zinc <106.9 μg/dL (median), a significantly lower risk of first hemorrhagic stroke was found in those with plasma zinc ≥106.9 μg/dL (multivariate-adjusted odds ratio, 0.45; 95% CI, 0.21-0.94). Furthermore, the inverse plasma zinc-first hemorrhagic stroke association was significantly stronger in participants with body mass index ≥25.0 kg/m2 or plasma copper <100.1 μg/dL at baseline (Pinteraction <0.05 for both variables). However, there was no significant association between plasma zinc and first ischemic stroke (<103.3 versus ≥103.3 μg/dL [median]; multivariate-adjusted odds ratio, 1.16; 95% CI, 0.83-1.61). Conclusions- In this sample of hypertensive patients, we found a significant, inverse association between plasma zinc and first hemorrhagic stroke.

Abstract
There is no study to compare different class of antihypertensive drugs on new-onset diabetes mellitus (NOD) in elderly. We aimed to investigate the risk of antihypertensive drugs on NOD in elderly patients. The databases were retrieved in an orderly manner from the dates of their establishment to October, 2018, including Medline, Embase, Clinical Trials, and the Cochrane Database, to collect randomized controlled trials (RCTs) of different antihypertensive drugs in elderly patients (age > 60 years). Then, a network meta-analysis was conducted using R and Stata 12.0 softwares. A total of 14 RCTs involving 74 042 patients were included. The relative risk of NOD mellitus associated with six classes of antihypertensive drugs was analyzed, including placebo, angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs), calcium channel blockers (CCBs), diuretics, and β blockers. Patients with ACEIs or ARBs appeared to have significantly reduced risk of NOD compare with placebo: ACEIs (OR = 0.49, 95% CrI 0.28-0.85), ARBs (OR = 0.37, 95% CrI 0.26-0.52), while CCBs, diuretics, and β blockers appeared to have not significantly reduced risk of NOD mellitus compare with placebo: CCBs (OR = 1.10, 95% CrI 0.85-1.60), diuretics (OR = 1.40, 95% CrI 0.92-2.50), β blockers (OR = 1.40, 95% CrI 0.93-2.10). The SUCRA of placebo, ACEIs, ARBs, CCBs, diuretics, and β blockers was, respectively, 65.3%, 69.3%, 92.3%, 44.1%, 12.1%, and 16.5%. According to the evidence, ARBs have an advantage over the other treatments in reducing the risk of NOD in elderly patients.

Abstract
PURPOSE To determine whether erythromycin is non-inferior to metoclopramide in facilitating post-pyloric placement of self-propelled spiral nasoenteric tubes (NETs) in critically ill patients. METHODS A prospective, multicenter, open-label, parallel, and non-inferiority randomized controlled trial was conducted comparing erythromycin with metoclopramide in facilitating post-pyloric placement of spiral NETs in critically ill patients admitted to intensive care units (ICUs) of eight tertiary hospitals in China. The primary outcome was procedure success defined as post-pyloric placement (spiral NETs reached the first portion of the duodenum or beyond confirmed by abdominal radiography 24 h after tube insertion). RESULTS A total of 5688 patients were admitted to the ICUs. Of these, in 355 patients there was a plan to insert a nasoenteric feeding tube, of whom 332 were randomized, with 167 patients assigned to the erythromycin group and 165 patients assigned to the metoclopramide group. The success rate of post-pyloric placement was 57.5% (96/167) in the erythromycin group, as compared with 50.3% (83/165) in the metoclopramide group (a difference of 7.2%, 95% CI - 3.5% to 17.9%), in the intention-to-treat analysis, not including the prespecified margin of - 10% for non-inferiority. The success rates of post-D1 (reaching the second portion of the duodenum or beyond), post-D2 (reaching the third portion of the duodenum or beyond), post-D3 (reaching the fourth portion of the duodenum or beyond), and proximal jejunum placement and the incidence of any adverse events were not significantly different between the groups. CONCLUSIONS Erythromycin is non-inferior to metoclopramide in facilitating post-pyloric placement of spiral NETs in critically ill patients. The success rates of post-D1, post-D2, post-D3, and proximal jejunum placement were not significantly different.
