Efficacy and safety of Xiaoyao Pill combined with Western medicine in the treatment of schizophrenia: A Meta-analysis and Systematic review.

BACKGROUND: The efficacy and safety of Xiaoyao Pill combined with Western medicine in the treatment of schizophrenia are still inconclusive. This meta-analysis summarized relevant studies to compare the efficacy and safety of Xiaoyao Pill combined with Western medicine and Western medicine alone in the treatment of schizophrenia, aiming to provide guidance for clinical treatment. METHODS: In this meta-analysis, we searched PubMed, Embase, Cochrane Library, CNKI, Wanfang, CQVIP, and CBM databases from the establishment of the databases to August 2023. The study proposed to include studies that reported combination of Xiaoyao Pill with Western medicine and Western medicine alone in the treatment of schizophrenia, excluding published literature, unpublished literature, literature with incomplete or inadequate information, animal experiments, literature reviews and systematic studies. Data were analyzed using Review manager 5.3. RESULTS: About 9 studies (6 RCTs and 3 case-control studies) were included in this meta-analysis. The sample size ranged from 60 to 128, with a total of 779 patients, including 395 in the combined treatment group and 384 in the control group. Pooled results showed that the total effective rate of combined treatment group was significantly higher than that of Western medicine alone (OR = 4.21, 95% CI: 1.50-11.83, P = .006). Positive and Negative Syndrome Scale (PANSS) (-) (MD = -2.30, 95% CI: -3.72 ~ -0.89, P = .001) and PANSS (+) (MD = -2.60, 95% CI: -3.34 ~ -1.86, P < .00001) of combined treatment group were all significantly lower than that of Western medicine alone. Additionally, PRL levels of combined treatment group was significantly lower than that of Western medicine alone (MD = -28.78, 95% CI: -42.20 ~ -15.35, P < .0001). However, there was no significant difference in BPRS and total PANSS between combined treatment group and Western medicine alone group. Notably, pooled results showed that there was no significant difference in incidence of adverse events between combined treatment group and Western medicine alone group. CONCLUSION: The effective rate of Xiaoyao Pill combined with Western medicine in the treatment of schizophrenia is higher than that of Western medicine alone, which can effectively relieve the positive and negative symptoms of schizophrenia, and can significantly reduce the level of PRL. In the treatment of schizophrenia, clinicians can give priority to Xiaoyao Pill combined with Western medicine therapy.

Nano-sized Al2O3 particle-induced autophagy reduces osteolysis in aseptic loosening of total hip arthroplasty by negative feedback regulation of RANKL expression in fibroblasts.

Aseptic loosening is mainly caused by wear debris generated by friction that can increase the expression of receptor activation of nuclear factor (NF)-κB (RANKL). RANKL has been shown to support the differentiation and maturation of osteoclasts. Although autophagy is a key metabolic pathway for maintaining the metabolic homeostasis of cells, no study has determined whether autophagy induced by Al2O3 particles is involved in the pathogenesis of aseptic loosening. The aim of this study was to evaluate RANKL levels in patients experiencing aseptic loosening after total hip arthroplasty (THA) and hip osteoarthritis (hOA) and to consequently clarify the relationship between RANKL and LC3II expression. We determined the levels of RANKL and autophagy in fibroblasts treated with Al2O3 particles in vitro while using shBECN-1 interference lentivirus vectors to block the autophagy pathway and BECN-1 overexpression lentivirus vectors to promote autophagy. We established a novel rat model of femoral head replacement and analyzed the effects of Al2O3 particles on autophagy levels and RANKL expression in synovial tissues in vivo. The RANKL levels in the revision total hip arthroplasty (rTHA) group were higher than those in the hOA group. In patients with rTHA with a ceramic interface, LC3II expression was high, whereas RANKL expression was low. The in vitro results showed that Al2O3 particles promoted fibroblast autophagy in a time- and dose-dependent manner and that RANKL expression was negatively correlated with autophagy. The in vivo results further confirmed these findings. Al2O3 particles induced fibroblast autophagy, which reduced RANKL expression. Decreasing the autophagy level promoted osteolysis and aseptic prosthetic loosening, whereas increasing the autophagy level reversed this trend.

Cost-effective initial assessment strategies for thyroid nodules in iodine-adequate areas.

OBJECTIVE: In the initial assessment of thyroid nodules, thyrotropin (TSH) has very low sensitivity for assessing functional thyroid nodules (FTNs). The false negativity in FTNs and the false positivity in non-FTNs misinterpreted by TSH will raise unnecessary assessment costs. Therefore, the aim of this study is to explore the values of the TSH and color flow Doppler sonography (CFDS) combined strategies in reducing the unnecessary assessment costs. METHODS: 2383 patients with thyroid nodules were retrospectively analyzed, including 107 FTNs and 2276 non-FTNs. Four strategies including TSH, CFDS, Combination 1 (TSH+/CFDS+, TSH+/CFDS-, and TSH-/CFDS+ defined as positive; TSH-/CFDS- defined as negative) and Combination 2 (TSH+/CFDS+ defined as positive; TSH+/CFDS-, TSH-/CFDS+, and TSH-/CFDS- defined as negative) were separately used for initial assessment. The four strategies were compared using the testing cost ratio of fine-needle aspiration (FNA) to thyroid scintigraphy (TS) (marked as CFNA/TS) as main outcome measure. RESULTS: Compared with TSH, Combination 1 prevented 15.89 % of FTNs from unnecessary FNA, but increased the number of non-FTNs subjected to unnecessary 99mTc-TS by 9.31 %. Combination 2 prevented 5.32 % of non-FTNs from unnecessary TS, but increased the number of FTNs subjected to unnecessary FNA by 18.69 %. When CFNA/TS was <6.05, the lowest total cost was found in Combination 2. The TSH and Combination 1 were optimal at 6.05 ≤ CFNA/TS ≤ 12.47 and CFNA/TS > 12.47, respectively. CONCLUSIONS: The combined strategies can be used to supplement TSH in the initial assessment of thyroid nodules in iodine-adequate areas, depending on the testing costs of FNA and TS.

Inhibiting roles of berberine in gut movement of rodents are related to activation of the endogenous opioid system.

Although Berberine (BER) is popular in treating gastrointestinal (GI) disorders, its mechanisms are not clear yet. In order to investigate the effects and possible mechanism of BER on GI motility in rodents, we first explored GI motility by recording the myoelectrical activity of jejunum and colon in rats, and upper GI transit with a charcoal marker in mice. Then, the plasma levels of gastrin, motilin, somatostatin and glucagon-like-peptide-1 (Glp-1) were measured by ELISA or radioimmunoassay (RIA). Furthermore, endogenous opioid-peptides (ß-endorphin, dynorphin-A, met-enkephalin) were detected by RIA after treatment with BER. Our results showed that BER concentration-dependently inhibited myoelectrical activity and GI transit, which can be antagonized by opioid-receptor antagonists to different extents. The elevated somatostatin and Glp-1, and decreased gastrin and motilin in plasma, which were caused by BER application, also could be antagonized by the opioid-receptor antagonists. Additionally, plasma level of ß-endorphin, but not dynorphin-A and met-enkephalin, was increased by applying BER. Taken together, these studies show that BER plays inhibiting roles on GI motility and up-regulating roles on somatostatin, Glp-1 and down-regulating roles on gastrin, motilin. The pharmacological mechanisms of BER on GI motility and plasma levels of GI hormones were discovered to be closely related to endogenous opioid system.

Efficacy and safety of iron supplementation for the elderly patients undergoing hip or knee surgery: a meta-analysis of randomized controlled trials.

BACKGROUND: Anemia is a frequent co-morbidity in the elderly patients undergoing hip or knee surgery and is often associated with poor clinical outcomes. Mild to moderate anemia is often treated with intravenous or oral iron supplementation. However, the efficacy and safety of iron supplementation in treating anemia for the elderly patients undergoing hip or knee surgery remains controversial. METHODS: Only prospective, randomized studies that compared iron supplementation with no iron supplementation in the elderly patients undergoing hip or knee surgery were included. Six studies met the inclusion criteria: the target population consisted of patients undergoing hip or knee surgery treated with iron supplementation; the study was a published randomized trial. Each outcome measure tested was assessed for heterogeneity. If significant heterogeneity was present for more than 75%, data from the studies were not combined. If there was no significant heterogeneity (less than 40%), a weighted mean difference (WMD) or combined relative risk was calculated using a fixed effects model, while a random effects model was applied when heterogeneity was within 40% to 75%. RESULTS: Our meta-analysis demonstrated the increase of hemoglobin level in patients undergoing hip or knee surgery with iron supplementation. However, no significant difference on the length of hospital stay, morbidity, 1-mo mortality, the infection rate, the rate and volume of allogeneic blood transfusions, and the adverse drug effects was found between the patients with iron treatment and those without. CONCLUSION: Our meta-analysis suggested that iron supplementation was safe and effective in treating anemia for the elderly patients undergoing hip or knee surgery.
