Wumei Pills, a classic traditional Chinese medicine(TCM) formula, are widely used in the treatment of biliary ascariasis and diarrhea. In recent years, studies have shown that Wumei Pills have advantages in the treatment of type 2 diabetes mellitus(T2DM), while there are no relevant reports that systematically evaluate the efficacy of Wumei Pills in the treatment of T2DM. This study addresses this issue by systematically evaluating the efficacy and safety of Wumei Pills, aiming to provide an evidence-based basis for clinical practice. PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, and VIP were researched for the randomized controlled trial(RCT) involving Wumei Pills for the treatment of T2DM that were published from inception to September 2024. RevMan 5.3 was used for the Meta-analysis of the data. A total of 18 RCTs were included, with a total of 1 437 patients. Meta-analysis produced the following results.(1)Treatment group outperformed control group in terms of overall response rate(RR=1.28, 95%CI[1.14, 1.43], P<0.000 1), fasting blood glucose(FPG)(WMD=-0.69, 95%CI[-0.93,-0.46], P<0.000 01), two-hour postprandial plasma glucose(2hPG)(WMD=-0.74, 95%CI[-1.17,-0.31], P<0.000 7), glycated hemoglobin(HbA1c)(WMD=-0.39, 95%CI[-0.60,-0.18], P=0.000 3), high-density lipoprotein(HDL)(WMD=0.38, 95%CI[0.28, 0.48], P<0.000 01), and body mass index(BMI)(WMD=-1.41, 95%CI[-2.40,-0.42], P=0.005).(2)The two groups had comparable effects regarding total cholesterol(TC)(WMD=-0.53, 95%CI[-1.13, 0.08], P=0.09) and low-density lipoprotein(LDL)(WMD=-0.25, 95%CI[-0.56, 0.06], P=0.12).(3)Triglycerides(TG)(WMD=-0.28,95%CI [-0.59,0.03],P=0.08), sensitivity analysis showed potential reduction effect(WMD=-0.20,95%CI[-0.36,-0.04],P=0.01). Occurrence of adverse drug reaction(RR=0.43,95%CI [0.23,0.80],P=0.007), sensitivity analysis showed significant disappearance(RR=0.56,95%CI[0.26,1.22],P=0.14), suggesting that the efficacy of treatment group was not better than that of control group. The results indicate that the treatment of T2DM with Wumei Pills is greatly related to the improvement of glucose metabolism, lipid metabolism, and clinical efficacy. The findings provide a basis for clinical application of Wumei Pills in treating T2DM, while the conclusion remains to be verified by clinical studies with higher quality.

Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

The quality of drugs is a crucial premise for ensuring the safety and effectiveness of clinical medication, while quality control during the pharmaceutical process directly affects the quality and consistency of the final product formulation. However, there is a lack of a comprehensive and scientific system for assessing and optimizing the quality control level during the manufacturing process in the field of drug quality control. Therefore, this study proposed the concept of "pharmaceutical process omics", clarified its advantages in guiding drug production, and explored in depth the research approaches, diverse analytical techniques, and broad range of applications in drug quality control. In addition, this study anticipated the broad application prospects of pharmaceutical process omics in the field of drug quality control, aiming to provide a scientific basis for the development of pharmaceutical process quality control standards.

A growing global trend indicates a decline in semen quality, with a lack of physical activity identified as one of the contributing factors. Exercise is medication, and numerous studies have explored its effects on semen quality. However, there is no consensus on the most effective type and intensity of exercise for improving semen quality, owing to inconsistent findings across studies. These discrepancies may be attributable to variations in study populations ( e.g. , healthy versus infertile individuals) and research methodologies ( e.g., observational versus interventional studies). This paper reviews the existing literature from the databases PubMed, Web of Science, and Google Scholar, reclassifying articles on their subject and research designs to delineate the relationship between exercise and semen quality. It also summarizes the mechanisms through which exercise influences semen quality, including hormonal regulation, oxidative stress, and inflammatory factors.

OBJECTIVES: To analyze the differentially expressed exosomal miRNAs in patients with chronic heart failure (CHF) complicated by hyperuricemia (HUA) and explore their potential as novel diagnostic molecular markers and their target genes. METHODS: This study was conducted among 30 CHF patients with HUA (observation group) and 30 healthy volunteers (control group) enrolled between September, 2020 and September, 2023. Peripheral blood samples were collected from 6 CHF patients with HUA for analyzing exosomal miRNAs by high-throughput sequencing, and the results were validated in the remaining 24 patients using qRT-PCR. GO and KEGG enrichment analyses were performed to predict the the target genes of the identified differential miRNAs. We also validated the differentially expressed miRNAs by animal experiment. RESULTS: A total of 42 differentially expressed exosomal miRNAs were detected in observation group by high-throughput sequencing; among them, miR-27a-5p was significantly upregulated (P=0.000179), and miR-139-3p was significantly downregulated (P=0.000058). In the 24 patients with both CHF and PUA, qRT-PCR validated significant upregulation of miR-27a-5p (P=0.004) and downregulation of miR-139-3p (P=0.005) in serum exosomes. When combined, miR-27a-5p and miR-139-3p had a maximum area under the curve (AUC) of 0.899 (95% CI: 0812-0.987) for predicting CHF complicated by HUA. GO and KEGG enrichment analyses suggested that the differential expressions of miR-27a-5p and miR-139-3p was associated with the activation of the AMPK-mTOR signaling pathway to activate the autophagic response. We obtained the same conclusion from animal experiment. CONCLUSIONS Upregulated exosomal miR-27a-5p combined with downregulated exosomal miR-139-3p expression can serve as a novel molecular marker for diagnosis of CHF complicated by HUA, and their differential expression may promote autophagy in cardiomyocytes by activating the AMPK-mTOR signaling pathway.

BACKGROUND:Stem cells from human exfoliated deciduous teeth are widely used in the field of tissue repair and regeneration,but the tissue regeneration effect has limitations in practical applications.Using miRNA to intervene in the directional differentiation of stem cells from human exfoliated deciduous teeth is an important development direction fortissue repair and regeneration in the future.OBJECTIVE:To investigate the effect of miR-26b on the neurogenic and angiogenic differentiation of stem cells from human exfoliated deciduous teeth.METHODS:Dental pulp stem cells were isolated and extracted from human exfoliated deciduous teeth,and induced to differentiate into nerves and blood vessels.The expressions of neurogenic markers Nestin,NSE,βⅢ-Tubu lin,and angiogenic markers CD31,VEGFR2,ANG-1 and miR-26b were detected.Dental pulp stem cells were divided into blank control group,miR-26 overexpression group,and negative control group.RT-qPCR,cell immunofluorescence staining,and western blot assay were used to detect the expression changes of related markers of neurogenic and angiogenic induction of stem cells from human exfoliated deciduous teeth in each group.RESULTS AND CONCLUSION:(1)Stem cells from human exfoliated deciduous teeth had multi-directional differentiation potential and could differentiate into osteogenesis,adipogenesis,neurogenesis,and vasculogenesis.(2)The expression level of miR-26b increased during the neurogenic and angiogenic differentiation of stem cells from human exfoliated deciduous teeth.(3)Compared with the blank control group and negative control group,the mRNA expression of neuroblast-related genes βⅢ-Tubulin,Nestin,NSE and angiogenesis-related genes CD31,VEGFR2,and ANG-1 in stem cells from human exfoliated deciduous teeth in the miR-26b overexpression group was significantly increased(P＜0.01),βⅢ-Tubulin,Nestin,CD31,and VEGFR2 protein expression was significantly increased(P＜0.01).The above results show that overexpression of miR-26b can promote the neurogenic and angiogenic differentiation of stem cells from human exfoliated deciduous teeth.

Objective To study the expression levels and clinical significance of histone H3 trimethylation at lysine 4(H3K4me3),histone H3 trimethylation at lysine 27(H3K27me3)and modifying enzyme in placental tissue of patients with premature rupture of membranes(PROM)with chorioamnionitis.Methods Clinical data of 95 pregnant women treated in the Xi'an Gaoxin Hospital due to PROM from June 2021 to December 2023 were retrospectively collected,and they were divided into infected group and a non-infected group according to whether they were complicated with histological chorioamnionitis(HCA).Another 30 normal pregnant women were selected as the control group.Placental tissues of all subjects were collected and H3K4me3 and H3K27me3 levels were detected,and the expression levels of H3K4me3,H3K27me3 specific methyltransferase[mixed lineage leukemia protein-1(MLL1),Zeste enhancer homolog 2(EZH2)]and demethyltransferase[lysine-specific demethylase 5B(KDM5B),Jumonji domain-containing protein 3(JMJD3)]were detected by quantitative real-time PCR(qRT-PCR).The expression differences of H3K4me3,H3K27me3 and specific modifiers among the three groups and the correlation with the histological stage of HCA were analyzed.The Receiver operating characteristic curve(ROC)was plotted,the Area under curve(AUC)value was calculated,and H3K4me3 was evaluated.Predictive value of H3K27me3 for concurrent HCA infection.Result Compared with the control group,the levels of H3K4me3(0.08%±0.02%,0.12%±0.03%vs 0.25%±0.06%),MLL1 mRNA(1.32±0.16,1.44±0.23 vs 2.02±0.31),and JMJD3 mRNA(0.78±0.13,0.91±0.15 vs 1.53±0.23)in the infected and non-infected groups were significantly decreased(t=10.939～19.062),while the levels of H3K27me39(0.23%±0.05%,0.15%±0.03%vs 0.10%±0.02%),EZH2 mRNA(1.96±0.26,1.85±0.25 vs 1.15±0.29)and KDM5B(1.46±0.15,1.35±0.18 vs 0.94±0.12)were significantly increased(t=6.077～14.974),and the levels in the infected group were lower/higher than those in the non-infected group(t=2.017～10.688),with statistically significant differences(all P<0.05).There was a significant negatively correlation between H3K4me3 and H3K27me3 levels in placenta tissue of PROM(r=-0.604,P<0.05).The levels of H3K4me3,MLL1 and JMJD3 were negatively correlated with the histological stages of HCA(r=-0.646,-0.489,-0.503,all P<0.05).The levels of H3K27me3,EZH2 and KDM5B were positively correlated with the histological stages of HCA(r=0.632,0.515,0.520,all P<0.05).The cutoffvalues of H3K4me3 and H3K27me3 were 0.10%and 0.19%,respectively.The AUC(95%CI)value of the combined prediction of PROM combined with HCA infection was 0.896(0.882～0.947),and the sensitivity and specificity were 92.14%and 86.23%respectively,which was significantly higher than the diagnosis of a single index.Conclusion The levels of H3K4me3,H3K27me3 and modifying enzymes in the placenta tissue of PROM are closely related to HCA infection and histological stage,which has high clinical prediction value for HCA infection and is expected to be a new biomarker for clinical diagnosis.

Objective To explore the characteristics of fluid flow within loaded osteons under different boundary conditions.Methods The COMSOL Multiphysics software was used to establish a three-dimensional(3D)finite element model of osteons with different boundary conditions,and the variation rules of pore pressure and flow velocity of osteons under different inner wall pulsating blood pressures and outer wall elastic constraint conditions were analyzed.Results As the pulsatile blood pressure inside the osteon increased from 0 mmHg(1 mmHg=0.133 kPa)to 300 mmHg,the peak pore pressure within the osteon correspondingly increased from 26 kPa to 68 kPa.As the elastic constraint on the outer wall of osteons changed from being completely elastic to completely constrained,the peak pore pressure within osteons increased from 15 kPa to 26 kPa,and the peak flow velocity increased from 0.04 um/s to 0.07 um/s.Conclusions This study reveals the influence laws of changes in boundary conditions such as the pulsatile blood pressure on the inner wall and the elastic constraint on the outer wall of osteons on fluid flow characteristics within loaded osteons.These findings are conducive to a deeper understanding of the mechanical response mechanisms of bone tissues in both physiological and pathological states,and provide an important theoretical basrs for further researches on bone mechanotransduction.

Objectives:To investigate the predictive value of epicardial fat volume(EFV)and atrioventricular groove fat thickness(AVGT)—morphological biomarkers of epicardial adipose tissue—for major adverse cardiovascular events(MACE)in patients with dilated cardiomyopathy(DCM).Methods:This study enrolled 216 DCM patients.EFV and AVGT were obtained from cardiac magnetic resonance imaging(CMR).Patients were divided into event-free group(n=142)and event group(n=74)based on MACE occurrence during follow-up.Receiver operating characteristic(ROC)curve analysis was used to determine optimal cutoff values.Survival differences were assessed using Kaplan-Meier analysis,Cox proportional hazards regression analysis was used to identify independent risk factors,and restricted cubic spline(RCS)models were used to evaluate dose-response relationships.Results:AVGT and EFV were significantly higher in the event group than in event-free group(both P<0.05).ROC analysis identified optimal MACE-predicting cutoffs as follows:AVGT≥7.74 mm(area under the curve[AUC]=0.57)and EFV≥78.6 ml(AUC=0.62).Kaplan-Meier analysis revealed significantly lower MACE-free survival rates in patients with AVGT≥7.74 mm and EFV≥78.6 ml(both P<0.05).Cox regression analysis confirmed that AVGT(HR=2.18,95%CI:1.34-3.54)and EFV(HR=1.81,95%CI:1.11-2.96)were independent MACE risk factors(both P<0.05)in this patient cohort.RCS models demonstrated the significant linear associations between EFV/AVGT and MACE risk(bothoverall P<0.05).Conclusions:EFV and AVGT,the non-invasive imaging biomarkers quantifying and characterizing fat distribution,are independently correlated with elevated MACE risk in DCM patients.These metrics serve as potential prognostic indicators,enriching risk stratification indicators for early identification of high-risk patients and guiding personalized medication strategies.

Objective:To evaluate the radiological and functional outcomes of moderate to severe hallux valgus patients with enlarged distal metatarsal articular angle (DMAA) underwent modified Chevron osteotomy.Methods:The clinical data of patients with moderate and severe hallux valgus with increased distal metatarsal joint angle who accepted surgery operation in the Department of Foot and Ankle Surgery of Yantaishan Hospital from October 2020 to December 2022 were retrospectively analyzed. All patients underwent modified Chevron osteotomy. Taking the proximal end of the metatarsal head centre as the osteotomy apex, the vertical arm osteotomy line in the sagittal plane made an angle of ≤80° with the metatarsal stem, the horizontal plane was inclined to the lateral distal end of the metatarsal head by about 10°, and the sagittal plane metatarsal arm osteotomy line made an angle of ≥90° with the vertical arm osteotomy line; at the proximal osteotomy surface, another cuneiform bone with its base on the medial and its apex on the lateral was resected. The deformity correction was insufficient and Akin osteotomy was performed in combination. Weil osteotomy was performed in combination with metatarsalgia. Radiological assessment including the hallux valgus angle (HVA), intermetatarsal angle (IMA), DMAA, the joint congruity angle (JCA), forefoot bone width and soft tissue width was performed preoperatively and at last follow-up postoperatively. American Orthopedic Foot and Ankle Society/hallux metatarsophalangeal-interphalangeal scale (AOFAS/HMIS) was used for clinical and functional evaluation, total score from 0 to 100, with higher scores indicating better function.Visual analogue scale (VAS) was used for pain valuation, total score from 0 to 10, with higher scores indicating more pain. A questionnaire survey on patient satisfaction was conducted at the last follow-up. Shapiro-Wilk test was used for normal distribution test, and measurement data following normal distribution were represented as Mean±SD. Paired t-test was used for comparison before and after operation. Other indicators conformed to non-normal distribution were denoted by M( Q1, Q3) and were tested by Wilcoxon signed-rank test. P<0.05 was considered statistically significant. Results:Fifty-two feet of 48 patients (5 males, 43 females; mean age (52.4±14.9) years; range, 24 to 78 years) were enrolled. Before the operation, 8 feet combined with metatarsalgia, among them, 7 feet underwent modified Chevron+ Akin+ Weil osteotomy, and 1 foot underwent modified Chevron+ Weil osteotomy. Among the 44 feet without metatarsalgia, 11 feet underwent modified Chevron osteotomy and 33 feet underwent modified Chevron+ Akin osteotomy. The mean follow-up time was 17.8 months (12-24 months). The HVA angle decreased from 38.30°±7.59° before surgery to 10.00°±5.73° at the last follow-up; the IMA angle decreased from 16.08°(12.89°, 18.24°) to 4.81°(3.62°, 7.57°); the DMAA angle decreased from 18.35°(13.03°, 27.47°) to 4.52°(2.68°, 7.09°); JCA decreased significantly from 15.93°(10.25°, 23.06°) to 3.56°(1.71°, 6.98°); forefoot bone width decreased from (90.05±6.12) mm to (82.75±5.01) mm; forefoot soft tissue width decrease from 102.25(96.77, 107.15) mm to 98.08(91.01, 100.60) mm; the VAS decreased from 6(5.5, 7) points to 0(0, 0) points; the score according to the AOFAS/HMIS forefoot was increased from 49(42, 52.5) points to 90(83.5, 95) points; which were statistically significant compared with that before the operation (all P<0.01). There was no statistically significant difference in the first metatarsal length before the operation and at the last follow-up [54.60(52.86, 56.42) mm vs. 54.29(51.85, 56.35) mm, P>0.05]. In the post-operative period, there were 8 feet had limited metatarsophalangeal joint movement, 3 feet had limited interphalangeal joint movement, 5 feet had limited movement in both joints, which did not affect walking and function; 3 feet of partial recurrence of hallux valgus, 2 feet of screw irritation pain, 1 foot of cystic degeneration of the first metatarsal head, and no complications such as metastatic metatarsalgia. The satisfaction survey showed that the satisfaction rate of patients with the orthopedic effect was 90.4% (47/52). Conclusion:The modified Chevron osteotomy is effective in the treatment of moderate to severe hallux valgus with enlarged DMAA. Careful intraoperative operation and standardized postoperative rehabilitation training can reduce complications.
