This study applied the grading of recommendations assessment, development and evaluation(GRADE) system and the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(Eff-iEC) to evaluate the evidence for 12 commonly used Chinese patent medicines for the treatment of osteoporosis, which are frequently recommended in guidelines or expert consensuses. The results showed that Xianling Gubao Capsules/Tablets were rated as C(low-level evidence) according to the GRADE system, and as BA~+B~+(intermediate evidence) according to the Eff-iEC system. Jintiange Capsules were rated as C(low-level evidence) by the GRADE system, and as AA~+B(high-level evidence) by the Eff-iEC system. Gushukang Granules/Capsules were rated as C(low-level evidence) by GRADE system, and as BA~+B~+(intermediate evidence) by Eff-iEC system. Zuogui Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Qianggu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B~+(high-level evidence) by Eff-iEC system. Zhuanggu Zhitong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BA~+B(intermediate evidence) by Eff-iEC system. Jingui Shenqi Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B(high-level evidence) by Eff-iEC system. Quanduzhong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AD~+B~+(low-level evidence) by Eff-iEC system. Epimedium Total Flavones Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AAB~+(high-level evidence) by Eff-iEC system. Yougui Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~(++)B~(+ )(high-level evidence) by Eff-iEC system. Qigu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BB~+B(intermediate evidence) by Eff-iEC system. Liuwei Dihuang Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Overall, the Eff-iEC system provides a more comprehensive assessment of the effectiveness evidence for traditional Chinese medicine(TCM) than the GRADE system. However, it still has certain limitations that hinder its wider promotion and application. In terms of clinical evidence evaluation, both the Eff-iEC and GRADE systems reflect that the current clinical research quality on Chinese patent medicines for the treatment of osteoporosis is generally low. High-quality clinical trials are still needed in the future to further validate clinical efficacy.

OBJECTIVE: Diabetes-induced gastrointestinal (GI) motility disorders are increasingly prevalent. Damage to the enteric nervous system (ENS), composed primarily of enteric neurons and glial cells, is an essential mechanism involved in these disorders. Although electroacupuncture (EA) has shown the potential to mitigate enteric neuronal loss, its mechanism is not fully understood. Additionally, the effects of EA on enteric glial cells have not been investigated. Enteric neural precursor cells (ENPCs) contribute to the structural and functional integrity of the ENS, yet whether EA enhances their differentiation into enteric neurons and glial cells remains unexplored. This study investigates whether EA promotes ENS repair through enhancing ENPC-derived neurogenesis and gliogenesis and elucidates the potential molecular mechanisms involved. METHODS: Transgenic mice were used to trace Nestin⁺/nerve growth factor receptor (Ngfr)⁺ ENPCs labeled with green fluorescent protein (GFP) in vivo. Mice were randomly divided into four groups: control, diabetes mellitus (DM), DM + sham EA, and DM + EA. The effects of EA on diabetic mice were evaluated by GI motility, ENS structure, and ENPC differentiation. Glial cell line-derived neurotrophic factor (GDNF)/Ret signaling was detected to clarify the underlying molecular mechanisms. RESULTS: EA alleviated diabetes-induced GI motility disorders, as indicated by reduced whole gut transit time, shortened colonic bead expulsion time, and enhanced smooth muscle contractility. Furthermore, EA attenuated diabetes-induced losses of enteric neurons and glial cells, thereby restoring ENS integrity. Notably, EA reversed the diabetes-induced decrease in ENPCs and significantly increased the absolute number and the proportion of ENPC-derived enteric neurons. However, immunofluorescence analyses revealed no colocalization between EA-induced glial fibrillary acidic protein⁺ glial cells and GFP-labeled ENPCs. Mechanistically, GDNF/Ret signaling was elevated in intestinal tissues and upregulated in ENPCs in EA-treated diabetic mice. CONCLUSION EA facilitates ENS repair by promoting Nestin⁺/Ngfr⁺ ENPC differentiation into enteric neurons via upregulation of GDNF/Ret signaling, and driving enteric gliogenesis from non-Nestin⁺/Ngfr⁺ ENPCs. These findings highlight EA's role in ameliorating diabetes-induced GI dysmotility through ENPC-derived ENS restoration. Please cite this article as: Guo JL, Liu S, Ding SJ, Yang X, Du F.

Objective:To investigate the diagnostic value of computed tomography(CT)combined with TaqMan probe for cardiopulmonary injury of pediatric patients with mycoplasma pneumonia of different clinical features.Methods:The medical records of 80 pediatric patients with mycoplasma pneumonia admitted to Shijiazhuang Maternal and Child Health Care Hospital from March 2020 to March 2023 were collected,and they were divided into<1 year old group(29 cases),1-3 years old group(23 cases)and>3 years old group(28 cases).They also were divided into long disease course group(43 cases,the disease course>7 d)and short disease course group(37 cases,the disease course≤7 d).All of pediatric patients underwent CT combined with TaqMan probe method to detect the cardiopulmonary injury,and to analyze the incidences of cardiopulmonary injury in pediatric patients of different age groups and different disease course groups.The CT and TaqMan probe were adopted to detect the pleural effusion,myocardial thickness,cardiothoracic ratio and the expression level of mycoplasma nucleic acid,and receiver operating characteristic(ROC)curves were adopted to analyze the diagnostic value of CT and probe in detecting cardiopulmonary injury of patients with mycoplasma pneumonia.Results:CT imaging showed that typical pulmonary abnormalities were present in patients of 62.5%,with a diagnostic accuracy of 93.75%(75/80),which main findings were pulmonary ground glass nodules(GGO),combined bacterial pneumonia and reticulation.Bronchiectasis was found in a small portion of patients.Bilateral pulmonary involvement was found in patients with pulmonary abnormalities,and the involvement of lower lobe was the most obvious in them.The 38 pediatric patients with clinically suspected incidental pulmonary embolism(PE)received additional CT examination with contrast agent,and the 24 pediatric patients of them were diagnosed as PE,and the diagnostic accuracy was 63.15%(24/38).TaqMan probe method was adopted to detect mycoplasma infection,and a high sensitivity and wide dynamic range detection system was established,which could conduct six times of dilutions for 10-fold between 0.2-0.2×10-5.Preparation was performed in 1 ng/μ l microbial community(MMC)-DNA standards,which had high linear dynamic range of 6 times of log10 dilutions with regression coefficient of R2=1.The detection lower limit was found to be 2×10-15 g/μl DNA.The incidence of cardiopulmonary injury gradually decreased with increasing age of pediatric patients with mycoplasma pneumonia of different ages.The incidences of cardiopulmonary injury in pediatric patients with mycoplasma pneumonia of<1 year old group,1 to 3 years old group and>3 years old group were respectively 93.10%,73.91%and 21.43%,and there were significant differences among the 3 groups(x2=7.660,33.019,P<0.05).The incidence(93.02%)of cardiopulmonary injury of long disease course group was significantly higher than that of short disease course group(27.03%),and the differences were statistically significant(x2=12.070,36.960,P<0.05),respectively.The amount of pleural effusion in the cardiopulmonary injury group was significantly higher than that in the non-cardiopulmonary damage group,and the myocardial thickness of cardiopulmonary injury group was significantly increased at the same time,and the cardiothoracic ratio of cardiopulmonary injury group was also significantly higher than that of non-cardiopulmonary injury group.There was significant difference in the expression level of mycoplasma nucleic acid(t=9.52,3.33,4.22,10.00,P<0.05).ROC curve analysis showed that the AUC value of CT combined with TaqMan probe method was larger than 0.5 in diagnosing cardiopulmonary injury of pediatric patients with mycoplasma pneumonia of different clinical features,and the AUC value of the combined diagnosis was largest.Conclusion:CT combined with TaqMan probe method has higher diagnostic value for the cardiopulmonary injury of pediatric patients with mycoplasma pneumonia.It should be considered to conduct the diagnosis of cardiopulmonary injury for pediatric patients who persistently exist the clinical symptom of mycoplasma pneumonia.The adaptation of existing TaqMan probe method,and the further expanded dPCR detection combination would improve the microbial diagnostic toolbox,which would provide reliable quantitative data for treatment decisions to cardiopulmonary injury of pediatric patients with mycoplasma pneumonia.

Deep vein thrombosis(DVT)is a common peripheral vascular disease in clinical practice.The lack of precise and efficient early diagnostic techniques renders it susceptible to being overlooked or misdiagnosed,and therefore,identifying trustworthy biomarkers is a major issue that has to be resolved.In this study,the endogenous metabolites in the urine of DVT rats were screened by metabolomics technology based on gas chromatograph-mass spectrometry(GC-MS)and the characteristic metabolites were identified by multiple feature selection algorithms and multivariate statistical analysis,for the development of a machine learning-based diagnostic model for DVT.The urine samples in metabolic cage in the thrombus development phase(between 48 and 72 h)of rats were collected,which was used as the models for inferior vena cava ligation.The metabolic profiles of the control group and DVT were obtained using the GC-MS method.A total of 176 kinds of endogenous metabolites were identified in rat urine through comparison with the FiehnLib database,26 kinds of differential metabolites associated with DVT were screened through a combination of the Mann-Whitney U test and orthogonal partial least squares discriminant analysis(OPLS-DA),and 13 kinds of significant metabolites strongly correlated with DVT were further evaluated in conjunction with various machine learning feature selection techniques.For DVT diagnosis,machine learning models such as Gaussian Naive Bayes(GNB),support vector machine(SVM),logistic regression(LR),and linear discriminant analysis(LDA)were developed.The diagnostic model constructed using 13 kinds of key metabolites demonstrated excellent accuracy and stability,and surpassed the predictive performance of the models utilizing 176 kinds of metabolites and 26 kinds of differential metabolites,as evidenced by examination and comparison of each model's efficacy.The study showed that the integration of multiple feature selection algorithms for analyzing metabolite information in DVT rat urine was capable of effectively identifying reliable potential markers of DVT.Furthermore,the developed machine learning model offered a novel technical approach for the automated diagnosis of DVT.

Objective To evaluate clinical efficacy and safety of ABO-incompatible (ABOi) living-related kidney transplantation. Methods Clinical data of 23 recipients undergoing ABOi living-related kidney transplantation were retrospectively analyzed. According to the initial blood group antibody titers in the recipients before surgery, different individualized pretreatment regimens were adopted, including oral intake of immunosuppressive drugs plus rituximab, or oral intake of immunosuppressive drugs plus plasma exchange and/or double filtration plasmapheresis plus rituximab. The blood group antibody titers before and after pretreatment, before and after kidney transplantation, and perioperative renal function and related complications were monitored. Renal allograft function and related complications were observed during postoperative follow-up. Results Among 23 recipients undergoing ABOi living-related kidney transplantation, except for one case presenting with hyperacute rejection during operation, the serum creatinine levels of the remaining 22 recipients were restored normal. Perioperative complications included lymphatic fistula in 4 cases, 1 case of urinary fistula, 1 case of perirenal hematoma complicated with T cell-mediated rejection, 6 cases of urinary system infection, 1 case of acute tubular necrosis, 1 case of acute pancreatitis, 1 case of blood group antibody titer rebound, and 1 case of primary disease recurrence, and all of these complications were cured after corresponding treatment. During postoperative follow-up, the graft and recipient survival rates of 22 recipients were 100%, and renal allograft function was normal. The blood group antibody titer were all ≤1:8 during follow-up. Complications during follow-up included 2 cases of severe lung infection, 1 case of antibody-mediated rejection, 2 cases of primary disease recurrence, 1 case of lymphocyst, 1 case of urinary system infection, 1 case of herpes zoster, 1 case of BK viruria and 2 cases of abnormal blood glucose levels. Conclusions ABOi living-related kidney transplantation may be safely performed by selecting individualized pretreatment regimens according to antibody titers by different blood groups. However, high-dose rituximab or combined use of rabbit anti-human thymocyte immunoglobulin may cause severe infectious complications in highly sensitized recipients.

Background Osteoclast stimulatory transmembrane protein (OC-STAMP) is involved in silicosis fibrosis induced by silicon oxide (SiO₂) exposure. Its role in silicosis fibrosis by inducing ferroptosis of alveolar type II epithelial cells and its related mechanism remain unclear. Objective To explore the effect and possible mechanism of OC-STAMP on ferroptosis of alveolar type II epithelial cells and silicosis fibrosis in rats under SiO₂ exposure. Methods Twenty male Wistar rats of SPF grade were randomly divided into two groups: control (Sham) group and SiO₂ group, 15 rats in each group. Rats in the SiO₂ group were given 1 mL of 50 mg·L⁻¹ SiO₂ suspension at one time through the non-exposed intratracheal instillation method to establish an animal model of silicosis, and rats in the Sham group were give 1 mL of 0.9% sodium chloride solution in the same way. Rats were sacrificed after 8 weeks. Samples of lung tissue were fixed in glutaraldehyde or paraformaldehyde for observing ultrastructure of mitochondria by transmission electron microscopy; HE, Masson, VG, and Prussian blue were used to observe changes in lung tissue structure and iron deposition. The expression level of OC-STAMP and the degree of lung fibrosis were evaluated by immunohistochemistry and immunofluorescence. The expression level of OC-STAMP in rat lung tissue was detected and the transfection effect of OC-STAMP was verified by real-time fluorescence quantitative polymerase chain reaction (RT-PCR). Overexpression (OCS group) and inhibition expression (SI-OC group) models were constructed by OC-STAMP plasmid and OC-STAMP small interfering RNA (siRNA) transfection to cultured MLE-12 cells, respectively. The relative expression levels of glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11), and other proteins in lung tissue and MLE-12 were detected by Western blotting. Results The results of HE, Masson, and VG staining showed that the silicosis modeling was successful after 8 weeks of SiO₂ exposure. The immunofluorescence results showed that OC-STAMP and ATP binding cassette subfamily A member 3 (ABCA3) co-localized in alveolar type II epithelium. The immunohistochemical results showed that the levels of OC-STAMP and collagen I in the SiO₂ group were significantly higher than those in the Sham group (P<0.01). The RT-PCR results showed that the OC-STAMP mRNA in the lung tissue of the SiO₂ group was significantly higher than that of the Sham group (P<0.01). The Prussian blue staining in the lung tissue of the SiO₂ group showed positive brownish-yellow particles. Compared with the Sham group which showed normal mitochondrial structure, the mitochondrial structure was generally swollen and the mitochondrial cristae dissolved and disappeared in the SiO₂ group by transmission electron microscope observation. The Western blotting results showed that the expression levels of SLC7A11 and GPX4 both decreased in the lung tissue of the SiO₂ group (P<0.05, P<0.01), and the expression level of Vimentin increased (P<0.01). In the transfected MLE-12 cells, compared with the Sham group, the expression levels of SLC7A11 and GPX4 in the OCS group were significantly reduced (P<0.05, P<0.01). Conclusion OC-STAMP may affect the expression of proteins related to ferroptosis, and promote lung fibrosis induced by SiO₂ exposure.

Evidence-based medicine plays an important role in promoting the scientific nature of clinical decision-making. Howe-ver, there is a problem where evidence derived from clinical research may not necessarily be applicable to individual patients. Evidence-based medicine has been introduced into the field of traditional Chinese medicine(TCM) for over 20 years, and although certain achievements have been made, the overall level of clinical research evidence based on the principles of evidence-based medicine in TCM is not high. The acceptance of TCM diagnosis and treatment guidelines developed based on evidence-based medicine methods is generally low. As revealed by the analysis of the problems in the application of evidence-based medicine in the field of TCM, it is found that there is a structural contradiction between clinical randomized controlled trial(RCT) of TCM and the characteristics of TCM clinical practice. They cannot comprehensively, objectively, and truthfully reflect the clinical efficacy and safety of TCM. Conducting clinical RCTs of TCM in pursuit of "evidence" actually means giving up the advantages of TCM in clinical treatment based on syndrome differentiation, prescription changes along with syndromes, and treatment in accordance with three categories of disease cause, which leads to sacrificing some clinical effectiveness of TCM. Based on the concept of evidence-based medicine, this article proposed the construction of "clinical syndrome-based medicine" based on the optimal clinical experience, which was suitable for the characteristics of TCM clinical practice. The key to clinical syndrome-based medicine is the optimal clinical experience, and the core elements of the optimal clinical experience are regularity and reproducibility. Real-world research methods are recommended as a reference for obtaining the optimal clinical experience. Clinical syndrome-based medicine, combining the characteristics of TCM clinical practice and incorporating the concept of evidence-based medicine, is the product of integrating TCM into evidence-based medicine. It is dedicated to improving the clinical efficacy of TCM along with evidence-based medicine.

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.
