"Sinew prescription correspondence" is the principle of selecting prescriptions for channel sinew diseases. On the basis of the theory of syndrome differentiation and treatment， the pulse manifestation corresponds to the channel sinew syndrome， which can improve the flexibility and standardization of clinical prescriptions. From the perspective of systematic dialectical sphygmology， this paper explains the dialectical relationship between channel sinew theory and pulse body elements， pulse wall elements， pulse elements and blood flow elements， and clarifies the internal relationship between pulse manifestation and prescriptions at the level of channel sinew disease. The prescription is derived from the method， while the method is established with the syndrome， and the prescription is unified by the method. According to the theory of "sinew prescription correspondence"， the treatment ideas of channel sinew diseases were analyzed from the perspective of channel sinew distribution， functional characteristics and structural changes. On this basis， the diagnosis of channel sinew disease and the application of prescriptions are expanded， and the research on the internal treatment and diagnosis mode of "pulse manifestation-channel sinew-zang fu （脏腑）" is prospected， so as to expand the differentiation and treatment methods of channel sinew theory.

Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

[摘 要] 目的：探讨核仁小RNA（snoRNA）71A通过TLR3/PD-L1通路对食管鳞状细胞癌（ESCC）细胞增殖、迁移及侵袭能力的影响。方法：qPCR检测52例ESCC患者的配对肿瘤组织、癌旁组织，以及人ESCC细胞中SNORA71A的表达情况。将反义寡核苷酸（SNORA71A-ASO-29、SNORA71A-ASO-102和NC-ASO）或小干扰RNA（siTLR3、siTLR3-NC）分别转染至人ESCC TE-1细胞，分别记为SNORA71A-ASO1组、SNORA71A-ASO2组、NC-ASO组及siTLR3组、siNC组。另外将过表达质粒pcDNA3.1-SNORA71A和pcDNA3.1空载体质粒分别转染至TE-1细胞，分别记为SNORA71A组和Vector组。细胞功能学实验（MTS实验、划痕愈合实验，以及Transwell侵袭实验）评估各组细胞在敲低或过表达SNORA71A后增殖、迁移和侵袭能力的变化。高通量转录组测序筛选SNORA71A下游作用靶基因，基因本体论（GO）和京都基因与基因组百科全书（KEGG）功能富集分析预测SNORA71A下游作用靶基因可能参与的生物学过程和信号通路。qPCR检测测序筛选出的下游作用靶基因TLR3在ESCC组织以及细胞中的表达。同时，qPCR和WB检测TE-1细胞在敲低或过表达TLR3后PD-L1 mRNA和蛋白质表达变化。细胞功能学实验检测TLR3敲低对SNORA71A所促进的TE-1细胞恶性生物行为（增殖、迁移、侵袭）的影响。结果：在52例ESCC患者的肿瘤组织以及ESCC细胞中SNORA71A表达均呈高水平（P < 0.01或P < 0.05）。敲低SNORA71A抑制TE-1细胞增殖、迁移和侵袭（P < 0.01或P < 0.05），过表达SNORA71A则促进TE-1细胞增殖、迁移和侵袭（P < 0.01或P < 0.05）。高通量转录组测序筛选到TLR3为SNORA71A下游作用靶基因。TLR3在ESCC组织以及TE-1细胞中呈低表达（P < 0.01或P < 0.05）。TLR3正向调控PD-L1 mRNA和蛋白质表达（P < 0.01或P < 0.05）。细胞功能学实验中，TLR3可以部分削弱SNORA71A对PD-L1表达的调控（P < 0.01）。结论：SNORA71A通过调控TLR3/PD-L1通路调节TE-1细胞增殖、迁移和侵袭。

Objective To systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. Methods Computer searches were conducted on PubMed, Cochrane Library, and Embase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. Results A total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the trial group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. Conclusion Female patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective To explore the predictive performance of machine learning models integrating clinico-pathological features and inflammatory markers for lymphovascular invasion (LVI) before gastric cancer surgery. Methods A retrospective cohort of 193 gastric cancer patients from The First Hospital of Lanzhou University (training set) and 185 patients from Zhongshan Hospital, Fudan University (validation set) was included. Preoperative clinical pathological characteristics, tumor markers, and inflammatory markers were collected to identify independent risk factors for LVI. Six machine learning models were established in the training set. Model performance was evaluated using area under the receiver operating characteristic (ROC) curve (AUC), calibration curve, decision curve analysis (DCA), and Brier scores. Shapley additive explanations (SHAP) was applied for model interpretability. Results The multivariate logistic regression showed increased tumor invasion depth (T-stage), lymph node metastases (N-stage), and the systemic immune-inflammation index (SII) were independent risk factors for gastric cancer LVI (P＜0.05). Using these three indicators, 6 machine learning models were developed, all of which demonstrated favorable predictive performance, with 0.79 and 0.76 of minimum AUC values in the training set and the validation set, respectively. Among them, the light gradient boosting machine (LightGBM) model exhibited the best overall performance, achieving AUCs of 0.83 and 0.82 in the training set and the validation set, along with Brier scores of 0.163 and 0.187, respectively. Calibration and DCA curves further confirmed that the model possesses strong predictive accuracy and application value. SHAP analysis showed the feature importance in LightGBM model, identifying the N-stage as the top contributor, followed by the T-stage and the SII. Conclusion The machine learning models incorporating clinical pathological features and inflammatory indicators can effectively predict LVI status in gastric cancer, with the LightGBM model demonstrating optimal performance.
