ObjectiveTo observe the effects of Yangjing Zhongyutang （YJZYT） on mitochondrial biogenesis and oxidative stress damage mediated by the silent information regulator 1 （SIRT1）/peroxisome proliferator-activated receptor gamma coactivator-1alpha （PGC-1α） signaling pathway in cyclophosphamide （CTX）-induced rats with diminished ovarian reserve （DOR）， and to explore its mechanism in improving ovarian reserve function and follicular development. MethodsForty-two 8-week-old female SD rats with normal estrous cycles were randomly divided into a blank control group （n=7） and a model group （n=35）. Rats in the model group received a single intraperitoneal injection of CTX （90 mg·kg^-1） to establish the DOR model. After modeling， estrous cycles were monitored for 7 consecutive days， and model success was confirmed based on criteria for estrous cycle disruption. After successful modeling， rats were divided into groups for intervention： estradiol valerate group （0.09 mg·kg^-1）， and YJZYT high-， medium-， and low-dose groups （19.98， 9.99， 5.00 g·kg^-1）. The blank control group and model group were given an equal volume of distilled water by gavage. All groups received daily gavage once for 4 consecutive weeks. The general state， body weight， and ovarian wet weight of rats were observed and recorded， and the ovarian organ index was calculated. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， anti-Müllerian hormone （AMH）， superoxide dismutase （SOD）， and glutathione peroxidase （GSH-Px）. Hematoxylin-eosin （HE） staining was performed to observe ovarian histomorphological changes and follicular development status. Immunofluorescence was used to detect reactive oxygen species （ROS） expression levels. Colorimetric assays were employed to measure adenosine triphosphate （ATP） and malondialdehyde （MDA） content in ovarian tissues. Quantitative Real-time polymerase chain reaction （Real-time PCR） was used to detect mitochondrial DNA （mtDNA） copy number and the mRNA expression levels of key genes including SIRT1， PGC-1α， nuclear respiratory factor 1 （NRF1）， and mitochondrial transcription factor A （TFAM）. Western blot was performed to detect the protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM. ResultsCompared with the blank group， rats in the model group exhibited disrupted estrous cycles， obviously reduced body weight， and decreased ovarian index （P<0.05）. Ovarian histopathology revealed cortical thinning， loose structure， and a significant reduction in both primordial and growing follicles （P<0.01）. Serum FSH and LH levels were significantly elevated （P<0.01）， while E₂ and AMH levels were obviously reduced （P<0.05， P<0.01）. ATP content and mtDNA copy number decreased in ovarian tissue （P<0.01）， ROS expression increased， MDA levels rose， while SOD and GSH-Px activities obviously decreased （P<0.05， P<0.01）， mRNA and protein expression levels of SIRT1， PGC-1α， NRF1， and TFAM were obviously downregulated （P<0.05， P<0.01）. After treatment， compared with the model group， body weight and ovarian index obviously recovered in rats administered various doses of YJZYT （P<0.05）， serum E₂ and AMH levels increased， while FSH and LH levels obviously decreased （P<0.05， P<0.01）， ovarian tissue ATP content and mtDNA copy number were up-regulated， ROS and MDA levels decreased， and antioxidant enzymes SOD and GSH-Px activity obviously increased （P<0.05， P<0.01）， Gene and protein expression levels related to the SIRT1/PGC-1α /NRF1/TFAM signaling pathway were obviously up-regulated compared to the model group （P<0.05， P<0.01）， HE staining revealed that ovarian structure gradually recovered to integrity in all treatment groups， with a obviously increase in the number of primordial and growing follicles （P<0.05， P<0.01）. Granulosa cells were neatly arranged， indicating marked improvement in ovarian function. ConclusionYJZYT may improve ovarian function and follicular development in rats with diminished ovarian reserve by activating the SIRT1/PGC-1α signaling pathway， promoting mitochondrial biogenesis， enhancing mitochondrial function， and alleviating oxidative stress damage.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

ObjectiveTo verify the therapeutic effect of Yinqi Sanhuang Jiedu decoction （YQSH） on carbon tetrachloride （CCl₄）-induced hepatic fibrosis in mice， and to explore whether its effect was related to the inhibition of neutrophil infiltration and the formation of neutrophil extracellular traps （NETs）. MethodsThe 36 C57BL/6J mice were randomly divided into control group， model group， positive drug silybin （SF） group （55 mg·kg^-1·d^-1）， YQSH-L group， YQSH-M group， and YQSH-H group （8.325， 16.65， 33.3 g·kg^-1·d^-1， respectively），n=6 in each group. Except for the control group， mice in all other groups were intraperitoneally injected with CCl₄ to induce hepatic fibrosis. After successful modeling， each drug administration group was given the corresponding drugs by gavage for eight weeks. Hematoxylin-eosin （HE） staining， Sirius red staining and Masson staining were used to observe the pathological changes of liver tissue. Liver elasticity was detected by a color Doppler ultrasound system. Immunohistochemistry and real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） were performed to detect the protein expression and mRNA levels of C-X-C motif chemokine ligand 1 （CXCL1）， CXCL2 and CXCL5. Neutrophil levels were detected by flow cytometry. The expression of neutrophil elastase （NE） and myeloperoxidase （MPO） positive protein was observed by immunofluorescence. The contents of MPO， NE and CitH3 were detected by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the control group， the liver of the model group showed obvious inflammatory cell infiltration and collagen deposition， and the liver elasticity， CXCL1， CXCL2， CXCL5 expression， neutrophil level， and MPO， NE and CitH3 levels were significantly increased （P<0.05， P<0.01）. Compared with the model group， inflammatory cell infiltration and collagen deposition in the liver tissue of mice were reduced after YQSH treatment. Moreover， the liver elasticity was reduced （P<0.01）. The protein expression （P<0.01） and mRNA level of CXCL1， CXCL2 and CXCL5 were decreased（P<0.05，P<0.01）. The neutrophil level was decreased （P<0.01）， the expression of MPO and NE positive protein was significantly decreased（P<0.05，P<0.01）， and the levels of MPO， NE and CitH3 were decreased （P<0.05， P<0.01）. ConclusionThe anti-hepatic fibrosis effect of YQSH may be related to its inhibition of chemokines （CXCL1， CXCL2， CXCL5）， reduction of neutrophil infiltration， and inhibition of NETs generation.

Objective To evaluate the effectiveness of thermal tomography in breast cancer (BC) screening. Methods We conducted a general population-based BC screening in three regions of Hubei Province (Xiantao, Hongan, and Yangxin Districts). Participants underwent a questionnaire-based interview for baseline data collection. They then received a physical examination, thermal tomography, and ultrasound from doctors and technicians. We compared the efficacies, including sensitivity, specificity, and false-positive rates, of ultrasound and thermal tomography in BC screening. Results A total of 59 712 eligible women were included in this screening program. The BI-RADS 1, 2, 3, 4, and 5 accordance rates between the two screening methods were 0.9549, 0.8047, 0.9037, 0.3352, and 0, respectively. The overall accordance rate was 0.933 1. The kappa consistency results showed that the Cicchetti-Allison and Fleiss-Cohen kappa values were 0.7970 and 0.8583, respectively. Although the two methods had equal sensitivities, specificity was higher in thermal tomography than in ultrasound. The false-positive rate was lower in thermal tomography than in ultrasound. The area under the receiver operating characteristic (ROC) curve of thermal tomography was significantly larger than that of ultrasound. Conclusion The general consistency between thermal tomography and ultrasound in BC screening was high. Thermal tomography outperformed ultrasound in terms of specificity and diagnostic efficiency. Therefore, thermal tomography has a high application value for general population-based BC screening.

Objective To investigate the clinical effect of simultaneous use of three endoscopes(laparoscope,choledochoscope,and duodenoscope)combined with holmium laser in the treatment of gallstones complicated with common bile duct stones.Methods A prospective randomized controlled study was carried out.A total of 80 patients with cholecystolithiasis combined with choledocholithiasis in our hospital from August 2022 to January 2024 were selected and divided into three-endoscope group(n=40)and two-endoscope group(n=40)according to random number table method.Patients in the three-endoscope group underwent laparoscopic cholecystectomy(LC)and laparoscopic common bile duct exploration(LCBDE)combined with holmium laser lithotripsy,primary closure of the common bile duct,endoscopic retrograde cholangiopancreatography(ERCP),and endoscopic nasobiliary drainage(ENBD),while the two-endoscope group underwent LC+LCBDE+T-tube drainage.The intraoperative bleeding volume,operation time,hospitalization time,hospitalization costs,and postoperative complications between the two groups were observed and analyzed.Results There was no significant difference in intraoperative bleeding volume between the two groups[(55.6±14.3)ml vs.(53.2±16.3)ml,t=0.703,P=0.484].The operation time of the three-endoscope group was significantly longer than that in the two-endoscope group[214.5(171.5,246.8)min vs.178.0(151.0,227.8)min,Z=-2.069,P=0.039].The length of hospital stay in the three-endoscope group was significantly shorter than that in the two-endoscope group[(13.2±3.3)d vs.(16.2±3.7)d,t=3.864,P=0.001].The hospitalization costs were significantly higher in the three-endoscope group than those in the two-endoscope group[39 316.0(32 338.5,43 421.0)yuan vs.33 717.0(30 873.3,37 813.3)yuan,Z=-3.272,P=0.001].There were no significant differences in the incidence of postoperative pancreatitis[2.5%(1/40)vs.2.5%(1/40),χ2=0.000,P=1.000],the incidence of bile leakage[7.5%(3/40)vs.2.5%(1/40),χ2=0.263,P=0.615],and residual stone rate[7.5%(3/40)vs.0.0%(0/40),P=0.241]between the two groups.Forty cases in the three-endoscope group were followed up for 2-20 months,with a median of 13 months.One case of stone recurrence occurred at 8 months after surgery.Forty patients in the two-endoscope group were followed up for 1-21 months,with a median of 15 months.There was 1 case of stone recurrence at 6 and 10 months postoperatively,respectively.There was no statistically significant difference in stone recurrence rate between the two groups[2.5%(1/40)vs.5.0%(2/40),χ2=0.000,P=1.000].Conclusions LC+LCBDE combined with holmium laser lithotripsy,primary closure of the common bile duct,ERCP,and ENBD in the treatment of cholecystolithiasis and choledocholithiasis can shorten the hospitalization time.The replacement of T-tube with nasobiliary duct protects the function of the Oddi sphincter,which is more in line with the concept of minimally invasive surgery and worthy of clinical application.

Objective:To explore the clinical application value of DNA image cytometry ploidy analysis (DNA-ICM) in the pathological diagnosis of malignant pleural effusion.Methods:A retrospective case series study was conducted. The clinical data of 101 patients with pleural effusion from October to December 2021 in Shanxi Bethune Hospital were retrospectively analyzed. Liquid-based cytology (LBC) and DNA-ICM were performed on pleural effusion specimens. The sensitivity and specificity of the two methods were compared with the clinical diagnosis, imaging, biopsy, and follow-up results of the patients.Results:Among the pleural effusions of 101 patients, 39 were malignant pleural effusions and 62 were benign pleural effusions. The sensitivity of LBC and DNA-ICM in diagnosing malignant tumor cells in pleural effusions was 74.7% and 94.9%, respectively, and the specificity was 98.4% and 83.9%, respectively; the combination of the two had an increased diagnostic positivity rate compared with that of LBC alone [36.6% (37/101) vs. 28.7% (29/101)]. Seven cases with positive DNA-ICM but negative LBC result were followed up, and 1 case was diagnosed as small cell lung cancer. Conclusions:DNA-ICM can effectively improve the positive cytology detection rate of pleural effusion, and the combined detection of DNA-ICM and LBC can reduce the underdiagnosis rate of cytology, which is of great clinical value in the pathological diagnosis of malignant pleural effusion.
