The Traditional Chinese Medicine, GSZD, may have equal or superior effectiveness and safety for treating RA compared to Western RA drugs. It should be considered a viable alternative to Western medicine. However, more long-term research is needed in larger patient groups to better establish its safety and efficacy.

Asians have relatively low insulin secretion capacity and readily develop type 2 diabetes mellitus (T2DM) when insulin resistant. For that reason, insufficient insulin secretion is critical factor for Asians at the early stage of T2DM. ATP-binding cassette transporter1 (ABCA1) is a membrane protein responsible for cholesterol efflux and its function is also important for secreting insulin in pancreatic β-cells. Given the importance of its role, different polymorphisms of ABCA1 gene might contribute differently to the development of T2DM. Here, we analyzed the association between a variant form of ABCA1 gene called rs2230806 and the prevalence of T2DM in a large sample size by pooling all of the case-control studies published. Relevant case-control studies were identified by searching PubMed, EMBASE, Cochrane Library, Korean scientific database, Chinese medical databases, and the Indian medical database. The association was evaluated using five genetic models such as the allelic (AG), recessive (RG), dominant (DG), homozygous (HMG), and heterozygous (HTG) genetic models. Heterogeneity of each genetic model was determined by the I test. A total of eight studies (7 published studies and one data set from the Korean Genetic Epidemiology Study) were eligible, satisfying Hardy-Weinberg equilibrium and included 2755 T2DM patients (case) and 16 635 nondiabetic subjects (control). All subjects in the studies were Asians. Each genetic model exhibited heterogeneity. In all genetic models, rs2230806 had a significant association with prevalence of T2DM: AG (OR=0.78, 95% CI: 0.61-0.98), RG (OR=0.72, 95% CI: 0.51-1.03), DG (OR=0.73, 95% CI: 0.55-0.97), HMG (OR=0.62, 95% CI: 0.41-0.96), and HTG (OR=0.78, 95% CI: 0.61-0.99). There was no single study that changed the overall effects in allelic genetic model with random effects. No publication bias existed in any models except the RG model. In conclusion, middle-aged and elderly adults with the minor allele of rs2230806 will have a lower risk of T2DM. This is the first meta-analysis to evaluate the association in Asians.

Paeonia lactiflora Pallas (PL) and Poria cocos Wolf (PC) have been traditionally used to treat inflammatory diseases reported in Dongui Bogam and Shen Nong Ben Cao Jing, traditional medical books in Korean and China, respectively. We determined the efficacies and the molecular mechanisms of PL, PC, and PL + PC aqueous extracts on androgenetic alopecia (AGA) induced by testosterone propionate in C57BL/6 mice. The molecular mechanisms of PL and PC in AGA treatment were examined using experimental assays and network pharmacology. The AGA model was generated by topically applying 0.5% testosterone propionate in 70% ethanol solution to the backs of mice daily for 28 days while the normal-control (Normal-Con; no AGA induction) mice applied 70% ethanol. The 0.1% PL (AGA-PL), 0.1% PC (AGA-PC), 0.05% PL + 0.05% PC (AGA-MIX), and 0.1% cellulose (AGA-Con; control) were supplemented in a high-fat diet for 28 days in AGA-induced mice. Positive-control (AGA-Positive) were administered 2% finasteride daily on the backs of the AGA mice. Hair growth rates decreased in the order of AGA-PL, AGA-MIX, AGA-PC, AGA-Positive, and AGA-Con after 21 days of treatment (ED21). On ED28, skins were completely covered with hair in the AGA-PL and AGA-MIX groups. Serum testosterone concentrations were lower in the AGA-PL group than in the AGA-Con group and similar to concentrations in the Normal-Con group, whereas serum 17β-estradiol concentrations showed the opposite pattern with increasing aromatase mRNA expression (p < 0.05). In the dorsal skin, DKK1 and NR3C2 mRNA expressions were significantly lower, but TGF-β2, β-Catenin, and PPARG expressions were higher in the AGA-PL and AGA-PC groups than in the AGA-Con group (p < 0.05), whereas TNF-α and IL-6 mRNA expressions were lower in the AGA-PL, AGA-MIX, and Normal-Con groups than in the AGA-Con group (p < 0.05). The phosphorylation of Akt and GSK-3β in the dorsal skin was lower in AGA-Con than normal-Con, and PL and MIX ingestion suppressed their decrease similar to the Normal-Con. In conclusion, PL or PL + PC intake had beneficial effects on hair growth similar to Normal-Con. The promotion was related to lower serum testosterone concentrations and pro-inflammatory cytokine levels, and inhibition of the steroid hormone pathway, consistent with network pharmacology analysis findings.
