ObjectiveTo systematically evaluate the efficacy and safety of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines in the treatment of coronary microvascular disease （CMD）. MethodsPubMed， Cochrane Library， CNKI， Wanfang Data， and VIP were searched for the randomized controlled trials （RCTs） on the treatment of CMD with Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis with the time interval from inception to December 31， 2023. The primary outcome indicators included the index of microcirculatory resistance （IMR）， coronary flow reserve （CFR）， and corrected TIMI flow frame count （cTFC）. The secondary outcome indicators included symptomatic efficacy， left ventricular ejection fraction （LVEF）， hypersensitive C-reactive protein （hs-CRP）， nitric oxide （NO）， and adverse events. Cochrane risk-of-bias assessment tool 2.0 （RoB 2.0） and Stata 17.0 were used for literature quality evaluation and meta-analysis of the included RCTs. The Grading of Recommendations， Assessment， Development and Evaluation （GRADE） was used to evaluate the quality of evidence. ResultsA total of 36 RCTs were included in this study， involving 3 029 patients. Compared with conventional Western medicine alone， the combined use of Chinese patent medicines for reinforcing Qi and activating blood/expelling stasis and Western medicine reduced the IMR ［mean difference （MD）=-5.93， 95% confidence interval （95%CI） ［-8.73，-3.14］， n=382， P<0.01］， cTFC （MD=-9.35， 95%CI ［-13.94，-4.76］， n=618， P<0.01）， and hs-CRP ［standard mean difference （SMD）=-1.50， 95%CI ［-1.90，-1.11］， n=1 483， P<0.01］， improved the CFR （SMD=1.14， 95%CI ［0.08，2.19］， n=304， P=0.03）， symptomatic efficacy ［relative risk （RR）=1.36， 95%CI ［1.21，1.53］， n=756， P<0.01］， LVEF （MD=4.39， 95%CI ［2.31，6.47］， n=533， P<0.01）， and NO （SMD=3.16， 95%CI ［2.07，4.25］， n=946， P<0.01） of CMD patients. In terms of safety， the combined therapy reduced the occurrence of adverse events in CMD patients （RR=0.49， 95%CI ［0.29，0.82］， n=591， P=0.01）. GRADE showed moderate quality evidence for adverse events， low quality evidence for cTFC， symptomatic efficacy， LVEF， and NO， and very low quality evidence for IMR， CFR， and hs-CRP. ConclusionBased on microcirculatory function indicators， the combined use of Qi-reinforcing and blood-activating/stasis-expelling Chinese patent medicines and Western medicine may further improve the coronary microvascular function in CMD patients with good safety. The above conclusions remain to be verified with high-quality clinical trials.

Ferroptosis of chondrocytes is a significant contributor to osteoarthritis (OA), for which there is still a lack of safe and effective therapeutic drugs targeting ferroptosis. Here, we screen for anti-ferroptotic drugs in Food and Drug Administration (FDA)-approved drug library via a high-throughput manner in chondrocytes. We identified a group of FDA-approved anti-ferroptotic drugs, among which vitamin K showed the most powerful protective effect. Further study demonstrated that vitamin K effectively inhibited ferroptosis and alleviated the extracellular matrix (ECM) degradation in chondrocytes. Intra-articular injection of vitamin K inhibited ferroptosis and alleviated OA phenotype in destabilization of the medial meniscus (DMM) mouse model. Mechanistically, transcriptome sequencing and knockdown experiments revealed that the anti-ferroptotic effects of vitamin K depended on growth arrest-specific 6 (Gas6). Furthermore, exogenous expression of Gas6 was found to inhibit ferroptosis through the AXL receptor tyrosine kinase (AXL)/phosphatidylinositol 3-kinase (PI3K)/AKT serine/threonine kinase (AKT) axis. Together, we demonstrate that vitamin K inhibits ferroptosis and alleviates OA progression via enhancing Gas6 expression and its downstream pathway of AXL/PI3K/AKT axis, indicating vitamin K as well as Gas6 to serve as a potential therapeutic target for OA and other ferroptosis-related diseases.

Objective: To elucidate the potential mechanisms by which Chinese herbal medicine (CHM) regulates gut microbiota (GM) to influence the development of primary open-angle glaucoma (POAG). Methods: Data mining, network pharmacology, and Mendelian randomization (MR) analyses (two-sample design) were conducted in integration to systematically explore the CHM-GM-POAG axis. Literature-based data mining method was applied to identify frequently used herbs and herb pairs for POAG, and the properties and meridian tropism of the herbs were analyzed as well. Target prediction and pathway enrichment analyses were performed to identify shared molecular pathways among CHM components, GM, and POAG. MR analysis was performed to assess the genetically predicted causal associations between specific microbial taxa and POAG risk. Results: Our data mining work indicated that commonly used CHMs were mainly bitter and sweet in flavors and cold in property, with meridian tropism toward the liver, lung, and kidney. The predominant therapeutic effects of the CHMs included soothing the liver and regulating Qi, promoting blood circulation, and reducing fluid retention. Representative herb pairs were Shudihuang (Rehmanniae Radix Praeparata)-Gouqi (Lycii Fructus) with Zexie (Alismatis Rhizoma), Gouqi (Lycii Fructus)-Fuling (Poria) with Shudihuang (Rehmanniae Radix), and Juhua (Chrysanthemi Flos)-Gouqi (Lycii Fructus) with Zexie (Alismatis Rhizoma). Network pharmacology revealed overlapping targets involving antioxidative, anti-inflammatory, and metabolic regulation pathways. MR analysis demonstrated that higher abundances of Ruminiclostridium 6 [odds ratio (OR) = 0.73, 95% confidence interval (CI): 0.58 – 0.92, P = 0.007], Ruminococcaceae UCG-002 (OR = 0.77, 95% CI: 0.63 – 0.96, P = 0.018), Ruminococcus torques group (OR = 0.71, 95% CI: 0.57 – 0.90, P = 0.004), and Victivallis (OR = 0.82, 95% CI: 0.70 – 0.96, P = 0.016) were causally associated with reduced POAG risk, whereas Actinomyces (OR = 1.34, 95% CI: 1.06 – 1.68, P = 0.013) and Blautia (OR = 1.39, 95% CI: 1.01 – 1.90, P = 0.042) showed positive associations. Conclusion This study revealed potential causal links between GM and POAG and provided integrative evidence that CHM may modulate the microbiota to exert neuroprotective effects. These findings offer new integrative insights into the gut-eye axis and a theoretical basis for developing microbiota-targeted CHM strategies in glaucoma management.

This paper summarized PENG Qinghua's experience in treating age-related dry eye based on the theory of ministerial fire. Guided by the theory of ministerial fire， it is believed that the key pathogenesis of age-related dry eye is transgression of ministerial fire， and kidney yang deficiency-cold， kidney yin depletion， and spleen-earth insufficiency are the causes of transgression of ministerial fire. The general principle of treatment is to conceal the ministerial fire. For kidney yang deficiency-cold and floating ministerial fire， the treatment should tonify the kidney and warm yang， and return fire to its origin， with Yin Huo Decoction （引火汤）； for kidney yin depletion and frenetic stirring of ministerial fire， the treatment should tonify the kidney and supplement essence， enrich yin and reduce fire， with Sancai Fengsui Pellet （三才封髓丹）； and for spleen-earth insufficiency， and fumigation of ministerial fire， the treatment should strengthen and activate spleen qi， and reinforce soil and hidden fire， with Renshen Huangqi Decoction （人参黄芪汤）.

Objective:To research the efficacy and safety of robotic thyroidectomy and bilateral modified radical neck dissection through bilateral axillo-breast approach (BABA) .Methods:We retrospectively analyzed the clinical data of 37 patients with thyroid cancer who received bilateral modified radical neck dissection through the BABA at the Department of Thyroid and Breast Surgery of the 960th Hospital of the People’s Liberation Army from Jan. 2014 to Jan. 2023. There were 24 females and 13 males, and the average age of the patients was (33,22±10.53) years old. The tumor diameter, number of lymph node dissection and metastasis in the central and lateral regions, average operation time, average hospital stay, complications, and aesthetic score were recorded. SPSS 25.0 software was used for statistical analysis, and the measurement data was calculated using mean ± standard deviation ( ± s), and the counting data was expressed in percentages and numbers. Results:A total of 37 thyroid cancer patients underwent robotic bilateral regional lymph node dissection. The 37 patients received total thyroidectomy, bilateral central compartment and cervical lateral regional lymph node dissection. All the pathological types were papillary carcinoma, with a maximal tumor diameter of (1.47±0.85) cm. The average number of central lymph nodes dissected was 19.46±8.84, and there were (10.24±5.95) metastases; The average number of lymph nodes removed from the bilateral cervical region was 38.92±14.21, and there were (7.92±5.84) metastases. The average operation time was (288.05±77.09) min, the average length of stay in the hospital was (10.76±3.92) days, and the average length of stay in the hospital following surgery was (8.03±2.08) days. These patients had no permanent hypoparathyroidism, permanent recurrent laryngeal nerve palsy, infection, accessory nerve injury and phrenic nerve injury after operation. Transient hypoparathyroidism occurred in 15 patients, transient recurrent laryngeal nerve palsy occurred in 1 patient, and chyle leak occurred in 2 patients. One month after surgery, the aesthetic score was 9.51±0.69.Two patients were found lymph node metastases during the (27.81±15.10) months of follow-up, and received robotic cervical lymph node dissection with BABA.Conclusion:For carefully chosen thyroid cancer patients with bilateral lateral cervical region lymph node metastases, robotic bilateral cervical lymph node regional dissection via BABA is safe and feasible, and good cosmetic results can be obtained.

Objective To observe changes of thickness and elasticity of skeletal muscles in patients with type 2 diabetes mellitus(T2DM)and relative impact factors.Methods Totally 62 T2DM patients(T2DM group)and 60 healthy adults(HC group)were prospectively recruited.Shear wave elastography(SWE)technology was used to measure the maximum Young's modulus(Emax)of the rectus abdominis and gastrocnemius muscles under relaxed and contracted states in both groups.The thickness and elasticity modulus of the skeletal muscles under the two states were compared between groups.Multiple linear regression analysis was performed to screen impact factors of the elasticity modulus of the rectus abdominis and gastrocnemius muscles.Results No significant difference of muscle thicknesses of rectus abdominis,nor of gastrocnemius muscle was found between groups under relaxed and contracted states(all P＞0.05).Under both relaxed and contracted states,the Emax of the rectus abdominis and gastrocnemius muscle in T2DM group were all lower than those in HC group(all P＜0.05).Multiple linear regression analysis showed that in T2DM group,the elasticity modulus of the rectus abdominis and gastrocnemius muscle under both relaxed and contracted states decreased linearly with disease duration,fasting blood glucose(FBG)and glycosylated hemoglobin(HbA1c)(all P＜0.05).Conclusion The elasticity modulus of skeletal muscle decreased in T2DM patients,and the reducing scales linearly related to disease duration,FBG and HbA1c.

Objective:To analyze the factors influencing the theoretical score of graduation examination of standardized residency training in a class-A tertiary general hospital in Shanghai from 2018 to 2021, and establish prediction models, and to provide a reference for further improving the quality of residency training.Methods:We collected the data of 556 residents who participated in the residency training graduation examination at the hospital from 2018 to 2021. Binary regression and logistic regression analyses were used to determine the association of residents' basic information, their routine assessment results at the bases, and the base performance assessment score (indicating the bases' training quality) with theoretical graduation examination results; and prediction models for the theoretical graduation examination score were established, using binary regression and logistic regression methods to construct model datasets. SPSS 26.0 was used for statistical analysis.Results:From 2018 to 2021, a total of 556 people participated in the residency training graduation examination at the hospital. The first-time pass rate of the first station theoretical examination station was 97.48% (542/556). Trainees graduating from double first-class schools had the highest first-time pass rate of 98.09% (359/366); doctoral students had the highest first-time pass rate of 98.59% (140/142); and residents of the two-year training program had the highest first-time pass rate of 98.34% (297/302). According to the binary regression analysis of categorical variables such as residents' basic information, the base level was associated with whether residents passed the theoretical examination ( P<0.05). According to the logistic regression analysis of residents' routine assessment scores and the base performance assessment score, the annual theoretical assessment score, the first-time theoretical score of the national medical licensing examination, the annual professional performance test score, and the base performance assessment score were key factors affecting the theoretical graduation examination score ( P<0.05). In the regression analysis associated with the theoretical graduation examination score, the annual professional performance test score showed the highest regression coefficient and the highest variance inflation factor, indicating strong multicollinearity. Therefore, the annual professional performance test score was important in predicting the theoretical score of the graduation examination. Conclusions:This study used binary regression and logistic regression models to analyze the possible factors affecting the theoretical graduation examination score and the degree of association, and also established two prediction models of the theoretical graduation examination score to predict trainees at risk. Through implementing the concept of hierarchical progression, adding personalized tutoring, realizing information management for residency training, and providing intelligent early intervention, the pass rate of residency training graduation examination is expected to be further improved, ultimately achieving the purpose of improving the quality of residency training.

Objective To investigate the clinical application value of predicting the severity of acute pancreatitis(AP)based on MRI-T2WI radiomics nomogram.Methods A total of 375 patients with AP were analyzed retrospectively,who were divided into 281 cases in the training group and 94 cases in the validation group according to the ratio of 3∶1.Based on MRI-T2WI image,man-ual segmentation was performed for the pancreatic parenchyma.The radiomics feature were selected by feature extraction and dimen-sionality reduction,the support vector machine(SVM)classifier were used to construct the radiomics model.Logistic regression analysis was used to screen out independent risk factors,and an radiomics nomogram model was constructed in combined with the Radiomics score(Radscore),and the predictive performances of the models were evaluated.Results Receiver operating characteristic(ROC)curve analysis showed that the predictive efficacy of radiomics nomogram model[training group,area under the curve(AUC)=0.893;val-idation group,AUC=0.889]was higher than that of clinical model(training group,AUC=0.799;validation group,AUC=0.809)and radiomics model(training group,AUC=0.814;validation group,AUC=0.823).Conclusion The radiomics nomogram based on MRI-T2WI radiomics features and independent risk factors has high clinical application value for the prediction of AP severity.
