Abstract
Rhizoma polygonati (Huangjing, RP) has been used for a long history with many chemical components in inducing anti-cancer, anti-aging, anti-diabetes, anti-fatigue, and more prevention of diseases or acts as nutrition sources in food. Here we investigated RP extract combination with kinase inhibitors in anti-cell growth and blockade in pathways targeting kinases. Experimental investigation and network pharmacology analysis were applied to test the potent kinase-mediated signaling. Herbzyme activity was determined by substrate with optical density measurement. Extract of processed RP inhibits cell growth in a much greater manner than alone when applied in combination with inhibitors of mTOR or EGFR. Moreover, processing methods of RP from Mount Tai (RP-Mount Tai) play essential roles in herbzyme activity of phosphatase suggesting the interface is also essential, in addition to the chemical component. The network pharmacology analysis showed the chemical component and target networks involving AKT and mTOR, which is consistent with experimental validation. Finally, EGFR inhibitor could be associated with nano-extract of RP-Mount Tai but not significantly affects the phosphatase herbzyme activity in vitro. Thus the processed extract of RP-Mount Tai may play a dual role in the inhibition of cell proliferation signaling by both chemical component and nanoscale herbzyme of phosphatase activity to inhibit kinases including mTOR/AKT in potent drug delivery of kinase inhibitors.

Abstract
BACKGROUND Given the global epidemic of obesity, numerous strategies have been employed in the management of metabolic syndrome (MS) in this population. A meta-analysis was designed in the present investigation to evaluate the benefits of tea extract (TE) supplementation in MS in obesity. METHODS We conducted searches of published literature in MEDLINE, PsycINFO, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception in 1985 to May 2017. Randomized controlled trials (RCTs) which studied TE consumption in obesity with MS were analyzed. Results were summarized using weighted mean differences (WMDs), standardized mean differences (SMDs) or odds ratio (OR) by suitable effect model. RESULTS Sixteen eligible randomized controlled trials, including 1090 subjects were identified. Benefits were demonstrated on reduction of Body Mass Index (BMI) (SMD, -0.27; 95% CI, -0.40 to -0.15, P < 0.0001) and blood glucose (SMD, -0.22; 95% CI, -0.34 to -0.10, P = 0.0003), and increasing high-density lipoprotein (HDL) (SMD, 0.18; 95% CI, 0.01 to 0.35, P = 0.03). Limited benefits without significance were observed on blood pressure and other anthropometric, cholesterol, and biochemistry outcomes. All-cause adverse events were minimal (0.99; 95% CI: 0.55, 1.77, P = 0.97). CONCLUSIONS This meta-analysis suggests that consumption of TE supplementation in the obese with MS has beneficial effects on improvement of lipid and glucose metabolism, as well as in the facilitation of weight loss.

Abstract
Glycosides from the roots of Tripterygium wilfordii Hook. f. are used for the treatment of oral lichen planus (OLP), a chronic inflammatory disease affecting the oral mucosa. To investigate the effectiveness and safety of Tripterygium glycosides (TGs) for OLP treatment, we conducted a systematic review of 18 randomized controlled trials, comprising 1,339 participants, from international and Chinese databases. We evaluated outcomes of TGs alone or in combination with conventional treatments. In combination with topical glucocorticoids (TGCs), including triamcinolone acetonide and prednisone, the total effectiveness rate (risk ratio [RR], 1.17; 95% confidence interval [CI], 1.09-1.25; p < .00001), symptom score reducing index (mean difference [MD], -2.44; 95% CI, -3.12 to -1.77; p < .0001), and visual analog scale score (MD, -1.61; 95% CI, -2.22 to -1.00; p < .0001) were significantly improved. Patients treated with TGs combined with TGCs experienced lower recurrence rates (RR, 0.37; 95% CI, 0.18-0.76; p = 0.007). The occurrence of adverse events was not significantly different between the TGs groups and controls. The combination of TG and TGCs improved clinical efficacy and reduced recurrence without increasing the risk of adverse events. A high-quality multicenter clinical study is needed to corroborate these findings.

Abstract
BACKGROUND Acute respiratory tract infection (ARTI) should be deeply concerned all over the world. Panax ginseng (ginseng) as traditional Chinese medicine is widely used in the treatment and health care for respiratory diseases. However, only one similar systematic review based on common cold has been published in 2011. New studies have occurred and a new systematic evaluation which could describe ARTI is needed. METHODS AND ANALYSIS We will search for randomized control trials of ginseng on preventing acute respiratory tract infection in the following 8 databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED (via OVID) and 4 Chinese databases (Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and Wan fang Database). The time is limited from the construction of the library to April 2020. The selection of studies, data extraction and quality of assessment will be conducted independently by 2 reviewers. The morbidity of ARTI by assessing self-report, caregiver report or clinical confirmation will be considered as the primary outcome. ARTI-related death among children or adults, other adverse events, absenteeism, laboratory-confirmed infection will be regarded as secondary outcome. All reported side effects and adverse events will be included as safety outcomes. Standard meta-analysis will be performed using Rev Man software V5.3. RESULTS This study will provide a better understanding of the association between P ginseng and ARTI. CONCLUSION This systematic review may offer stronger evidences for the clinicians to prevent the patients from ARTI and update the former one based on basic diseases and the safety.

Journal of photochemistry and photobiology. B, Biology. 2019;:12-16
Abstract
The present work showed the green, eco-friendly synthesis of zinc oxide nanoparticles (ZnO NPs) using leaf extract of Cucurbita pepo. The prepared ZnO NPs were studied using different characterization techniques such as Fourier transform infrared (FTIR), X-ray diffraction (XRD), UV-Visible spectroscopy (UV-Vis) and Transmission electron microscopy (TEM). TEM images confirmed the formation of NPs with average size of 8 nm. XRD showed the crystalline nature of prepared ZnO NPs. This shows that the ZnO NPs induced cytotoxicity that affected the proliferation of MG63 osteoblast-like cells in a concentration dependent manner. Further, the ZnO NPs induced reduction in cell proliferation was confirmed by Fluorescein diacetate hydrolysis (FDA) staining. FDA staining results showed a reduction in fluorescence intensity with an increase in the concentration of ZnO NPs. The untreated control which was unaffected showed the highest fluorescence compared to ZnO NPs treated samples. A significantly diminished fluorescence was observed in samples incubated with 80 ppm ZnO NPs. In conclusion, these cell experimental results confirmed that the fabricated ZnO NPs are an important substitute for osteoporotic and bone tissue formation.

Abstract
To evaluate the efficacy and safety of total glucosides of peony (TGP) in adults with primary Sjögren's syndrome (pSS). A multi-center, randomized, double-blinded, placebo-controlled study was conducted between March 2012 and July 2014 at ten Chinese hospitals. In total, 320 pSS patients-classified according to the 2002 American-European Consensus Group Criteria-were randomized (2:1 ratio) to receive TGP(600 mg, tid) in the TGP group or placebo for 24 weeks in the placebo group. Study personnel, investigators, and patients were blinded to the treatment grouping. The primary endpoint was the improvement of EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) at week 24. The secondary endpoints were dry eyes/mouth/skin/nose/throat/vagina visual analogue scale (VAS), pain and discomfort VAS, fatigue VAS, mental discomfort VAS, patient global assessment (PGA), EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI), Schirmer's test, basal/stimulated salivary flow-rate values, and erythrocyte sedimentation rate (ESR). All adverse events were recorded during the trial period. ESSPRI improved more in the TGP than the placebo group (p < 0.001). Dry eyes/throat/vagina VAS, fatigue VAS, mental discomfort VAS, PGA, Schirmer's test, and ESR also improved more in the TGP group than in the placebo group (all p < 0.05). Stimulated salivary flow-rate values increased in the TGP group at week 12 but not at week 24. Adverse events in TGP group were 10.9%. TGP can alleviate some dryness symptoms as well as disease activity in pSS patients over 24 weeks. TGP was well tolerated by study subjects. TGP seems to be an effective and safe treatment for pSS.

Abstract
OBJECTIVES To compare the efficacy and safety of Tripterygium wilfordii Hook F (TwHF) with methotrexate (MTX) in the treatment of active rheumatoid arthritis (RA). METHODS Design: a multicentre, open-label, randomised controlled trial. All patients were assessed by trained investigators who were unaware of the therapeutic regimen. INTERVENTION 207 patients with active RA were randomly allocated (1:1:1) to treatment with MTX 12.5 mg once a week, or TwHF 20 mg three times a day, or the two in combination. At week 12, if reduction of the 28-joint count Disease Activity Score (DAS28) was <30% in the monotherapy groups, the patient was switched to MTX+TwHF. The primary efficacy point was the proportion of patients achieving an American College of Rheumatology (ACR) 50 response at week 24. RESULTS 174/207 (84.1%) patients completed 24 weeks of the trial. In an intention-to-treat analysis, the proportion of patients reaching the ACR50 response criteria was 46.4% (32/69), 55.1% (38/69) and 76.8% (53/69), respectively, in the MTX, TwHF and MTX+TwHF groups (TwHF vs MTX monotherapy, p=0.014; MTX+TwHF vs MTX monotherapy, p<0.001). Similar statistically significant patterns at week 24 were found for ACR20, ACR70, clinical Disease Activity Index good responses, EULAR good response, remission rate and low disease activity rate. Significant improvement in the Health Assessment Questionnaire and 36-item Short-Form Health Survey questionnaire scores from baseline to week 24 was seen in each treatment arm (p<0.05), though no significant difference was found among the treatment arms (p>0.05). The result of per-protocol analysis agreed with that seen in the intention-to-treat analysis. Seven, three and five women in the TwHF, MTX and combination groups, respectively, developed irregular menstruation (TwHF vs MTX monotherapy, p=0.216). CONCLUSIONS TwHF monotherapy was not inferior to, and MTX+TwHF was better than, MTX monotherapy in controlling disease activity in patients with active RA. TRIAL REGISTRATION NUMBER NCT01613079.
