Persistent left superior vena cava is a rare venous variant that is often combined with cardiovascular malformations. In thoracic surgery, especially mediastinal tumor resection, neglect of this variant may make the surgery difficult and risky, and careful preoperative imaging interpretation and adequate preoperative evaluation play an important role in the perioperative safety of the patient. In this paper, we reported a case of a 17-year-old female patient with a persistent left superior vena cava combined with mediastinal tumors. She was successfully discharged 5 days after thoracoscopic surgery, and after 3 years of postoperative follow-up, no tumor recurrence was observed.

OBJECTIVES: To evaluate the feasibility, efficacy and safety of Sentinel cerebral embolic protection device (CEPD) during transcatheter aortic valve replacement (TAVR). This study is a subgroup analysis of the China Moderate to Severe Valvular Heart Disease Registry, which has been registered at the Chinese Clinical Trial Registry (ChiCTR2300075006). METHODS: Patients undergoing TAVR with the Sentinel CEPD from October 2023 to September 2024 were retrospectively enrolled. A total of 80 patients were included, with a median age of 72 (68, 76) years, including 52 males (65.0%) and 28 females (35.0%); 62 patients (77.5%) with tricuspid valves, and 18 patients (22.5%) with bicuspid valves; 34 patients (42.5%) with type Ⅰ aortic arch, 24 patients (30.0%) with type Ⅱ aortic arch, 12 patients (15.0%) with type Ⅲ aortic arch, and 10 patients (12.5%) with bovine-type aortic arch. Clinical data of the patients were summarized and analyzed. The primary endpoints were success rate of Sentinel CEPD implantation, as well as all-cause death, symptomatic stroke, transient ischemic attack, and Sentinel CEPD access vessel complications during hospitalization and within 30 days postoperatively. RESULTS: In the 80 patients, self-expanding valves were used in 68 cases (85.0%) and balloon-expandable valves in 12 cases (15.0%). Seventy-nine patients (98.8%) successfully underwent TAVR with Sentinel CEPD deployment. Macroscopically visible debris was captured in 92.5% (74/80) by filters of Sentinel CEPD. Although the procedure time for Sentinel CEPD placement was slightly longer in patients with bovine-type aortic arch, there was no statistically significant difference in deployment time among different aortic arch types (P>0.05). During hospitalization and within 30 days postoperatively, only one case of transient ischemic attack occurred, and there was no all-cause mortality, symptomatic stroke, or access-site vascular complications related to the Sentinel CEPD observed. CONCLUSIONS The Sentinel CEPD demonstrates high feasibility across aortic arch types, potential efficacy in embolic capture, and excellent safety in TAVR.

Objective To compare the effect of sodium hualuronate(SH)and platelet rich plasma(PRP)injections in the treatment of glenohumeral joint osteoarthritis(GJO).Methods Sixty-three patients with GJO were randomly assigned to receive either PRP(PRP group,n=29)or SH(SH group,n=34)injec-tions.The injections were administered into the glenohumeral joint under ultrasound guidance.The patients were assessed by the Visual Analogue Scale(VAS),American Shoulder and Elbow Surgeons(ASES)score and modified University of California(UCLA)shoulder joint score before injection and at 1,6,12 months of injection.Results There were no statistically significant differences in the general data between the two groups(P>0.05).Compared with before injection,the VAS scores at 1,6,and 12 months after injection in the two groups were significantly decreased(P<0.05).The VAS score at 12 months after injection in the SH group was significantly increased(P<0.05).The VAS score at 12 months after injection in the PRP group was lower than that in the SH group(P<0.05).The ASES scores showed a significant increase at 1 month after injection compared to before treatment(P<0.05),moreover the ASES scores at 6 months after injection in the PRP group were higher than those in the SH group(P<0.05).Compared with before injection,the modified UCLA shoulder joint scores at 1,6 months after injection in the two groups were significantly in-creased(P<0.05),moreover the scores of the modified UCLA shouder joint scores at 6 months after injec-tion in the PRP group were higher than those in the SH group(P<0.05).Conclusion Pain relief in intraar-ticular injection of PRP in GJO patients is more significant than intraarticular injection of SH,moreover PRP is significantly superior to SH in improving the shoulder joint function of the patients.

Objective To investigate the feasibility of a "pericardial lining" modified Bentall procedure for the treatment of patients with aortic root aneurysm. Methods This was a retrospective study that consecutively enrolled patients treated at the Affiliated Suzhou Hospital of Nanjing Medical University, The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, and the First People's Hospital of Guangyuan from January 2023 to February 2024. Preoperative clinical data, imaging findings (including echocardiography and CT scans of the aortic root and the entire aorta), details of coronary artery management, surgical outcomes, and postoperative follow-up results were collected. All patients underwent the "pericardial lining" modified Bentall procedure: the aortic valve was replaced, and an autologous pericardial patch was divided into three equal leaflets based on the circumference of the aortic annulus measured by a valve sizer. These leaflets were then sutured to the aortic annulus. Fenestrations were created in two of the pericardial leaflets for anastomosis with the left and right coronary ostia. The pericardial leaflets were sutured to the wall of the aortic sinuses to form an integrated structure, thereby narrowing the sinus portion. A prosthetic vascular graft was anastomosed to the proximal and distal aorta, and no aortic root-to-right atrium shunt was created. Results A total of 5 patients, aged 37 to 68 years, were included. The preoperative Society of Thoracic Surgeons (STS) risk scores ranged from 2.8% to 3.9%. The diameter of the ascending aorta was 40-73 mm, the left ventricular end-diastolic diameter (LVEDD) was 45-71 mm, and the left ventricular ejection fraction (LVEF) was 47%-64%. Intraoperatively, the aortic cross-clamp time ranged from 85 to 180 min, and the cardiopulmonary bypass time ranged from 110 to 302 min. Postoperative follow-up echocardiography revealed that the ascending aortic diameter was 27-35 mm, LVEDD was 39-57 mm, and LVEF was 43%-61%. All surgeries were completed successfully with satisfactory immediate outcomes and no intraoperative complications. During the follow-up period, there was no mortality or reoperation. Conclusion For patients with aortic root aneurysm, the "pericardial lining" modified Bentall procedure yields satisfactory preliminary results, and the technique is demonstrated to be feasible.

BackgroundPostpartum depression （PPD） is a prevalent postpartum complications that significantly compromises women's psychological and physical well-being. Repetitive transcranial magnetic stimulation （rTMS）， a conventional neuromodulation technique， has been increasingly used in the treatment of PPD. However， high-quality evidence regarding its efficacy and safety remains limited. ObjectiveTo evaluate the efficacy and safety of rTMS in the treatment of PPD， thereby providing references for clinical treatment. MethodsDatabases including Cochrane Library， PubMed， Embase， CNKI， Wanfang， VIP and China Biology Medicine disc （CBM） were electronically searched for randomized controlled trials （RCTs） on rTMS for PPD， with the search spanning from database inception to February 8， 2025. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1， and the certainty of evidence was graded according to the Grading of Recommendations Assessment， Development and Evaluation （GRADE） approach. Meta-analysis was conducted using RevMan 5.3 and Stata 12.0. The outcomes of the Meta-analysis included the total effective rate， Edinburgh Postnatal Depression Scale （EPDS） score， Hamilton Depression Rating Scale （HAMD） score， and adverse reactions （dizziness， headache， nausea， diarrhea， and the overall incidence of adverse reactions）. ResultsA total of 11 studies involving 729 patients with PPD were included. Meta-analysis results showed that the total effective rate in the study group was significantly higher than that in the control group （OR=5.54， 95% CI： 3.07–10.01， P<0.01）. Both EPDS score （SMD=-2.38， 95% CI： -3.39–-1.37， P<0.01） and HAMD score （SMD=2.53， 95% CI： 1.21–3.85， P<0.01） in the study group were significantly lower than those in the control group， with statistically significant differences. Comparisons between the study group and control group reveal no significant differences in the incidence of dizziness and headache （RR=1.47， 95% CI： 0.63–3.43， P>0.05）， nausea （RR=1.46， 95% CI： 0.55–3.86， P>0.05）， diarrhea （RR=0.71， 95% CI： 0.23–2.20， P>0.05）， and overall adverse reactions （RR=1.30， 95% CI： 0.79–2.15， P>0.05）. GRADE assessment rated the four indicators of dizziness and headache， diarrhea， overall incidence of adverse reactions， and EPDS score as "moderate-certainty evidence"， and rated the total effective rate， nausea， and the HAMD score as "low-certainty evidence". ConclusionrTMS demonstrates certain therapeutic efficacy for PPD， with a safety profile comparable to conventional treatment. ［Funded by Sichuan Psychological Society Research Planning Project （number， SCSXLXH202403099）； Guiding Science and Technology Plan Project of Guangyuan （number， 23ZDYF0095）］

ObjectiveTo observe the effects of the South African herb Hoodia gordonii （HG） on glucolipid metabolism in diabetic db/db mice and explore the possible mechanisms of HG on the liver of db/db mice based on the phosphoinositide-3 kinase （PI3K）/protein kinase B （Akt）/factor forkhead protein O1 （FoxO1） signaling pathway. MethodA total of 30 db/db mice were randomly divided into five groups according to fasting blood glucose： model group， metformin group （0.195 g·kg^-1）， and low dose （0.39 g·kg^-1）， medium dose （0.78 g·kg^-1）， and high dose （1.56 g·kg^-1） HG groups， with six m/m mice in each group， and another six m/m mice were set as normal group. The mice in the normal and model groups were given saline of 9 mL·kg^-1 by gavage. Body weight， water intake， and fasting blood glucose of the mice in each group were measured weekly. After six weeks of continuous administration， serum insulin （FINS）， low-density lipoprotein cholesterol （LDL）， total cholesterol （TC）， triglyceride （TG）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine （CREA） were measured， and liver sections were embedded and stained with hematoxylin-eosin （HE）， periodic acid-Schiff （PAS）， and oil red O. Protein expression of PI3K p85， p-Akt， and p-FoxO1 in liver was detected by immunohistochemistry. The mRNA expression of PI3K， Akt， and FoxO1 in liver tissue was detected by real-time polymerase chain reaction （Real-time PCR）. ResultAfter six weeks of administration intervention， it was found that fasting blood glucose was significantly downregulated in mice in the three HG groups （P<0.05）. The level of islet resistance index was significantly reduced in both the low and medium dose HG groups （P<0.05）. The expression levels of TC， TG， and LDL were reduced in all HG groups （P<0.05， P<0.01）. Pathologically， HG could alleviate hepatocyte steatosis， reduce the volume and content of lipid droplets in liver， and increase the distribution of glycogen granules in liver to some extent in mice. Immunohistochemical assays revealed that PI3K p85 protein expression was significantly increased in the low， medium， and high dose HG groups compared with the model group （P<0.01）. p-Akt protein expression was significantly increased in the medium and high dose HG groups （P<0.05， P<0.01）. p-FoxO1 protein expression was significantly increased in the low， medium， and high dose HG groups （P<0.05， P<0.01）. Compared with the model group， PI3K mRNA was increased in low dose， medium dose， and high dose HG groups （P<0.05）， and Akt mRNA was increased in high dose HG group （P<0.05）. FoxO1 mRNA was decreased in low dose， medium dose， and high dose HG groups （P<0.05）. ConclusionHG can ameliorate the disorder of glucolipid metabolism in db/db mice， which may be related to its activation of the hepatic PI3K/Akt/FoxO1 signaling pathway.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

Objective:To investigate the clinicopathological characteristics of early gastric cancer with mixed histological staging, and to analyze the prognostic effect of endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Clinical data of early gastric cancer patients treated with ESD in Gansu Wuwei Cancer Hospital from January 2011 to March 2020 were collected, and clinicopathological characteristics of patients with mixed-type early gastric cancer were analyzed by descriptive statistical methods. The clinical effects and influencing factors of ESD on early gastric cancer were analyzed by logistic regression. Kaplan-Meier was used to estimate the survival rate, and log-rank test was used to compare the survival rate.Results:A total of 269 patients (280 lesions) were included in this study, including 216 males (80.30%) and 53 females (19.70%), with age of 60.43±8.01 years. There were 25 lesions (8.93%) of mixed early gastric cancer, 248 lesions (88.57%) of differentiated early gastric cancer, and 7 lesions (2.50%) of undifferentiated early gastric cancer. Compared with differentiated and undifferentiated early gastric cancer, the lesion site of mixed early gastric cancer was mainly located in the upper 1/3 of the stomach [64.00% (16/25), 40.73% (101/248) VS 0.00% (0/7), χ2=10.211, P=0.006], the proportion of the lesion size ≤2 cm was relatively small [52.00% (13/25), 80.65% (200/248) VS 85.71% (6/7), χ2=11.173, P=0.004], and the proportion of infiltration depth in the mucosa was lower [52.00% (13/25), 85.48% (212/248) VS 57.14% (4/7), χ2=20.019, P<0.001], the proportion of positive vertical resection margin was relatively high [20.00% (5/25), 2.82% (7/248) VS 0.00% (0/7), χ2=16.657, P<0.001], the proportion of vascular invasion was higher than that of differentiated carcinoma but lower than that of undifferentiated carcinoma [36.00% (9/25), 2.42% (6/248) VS 42.86% (3/7), χ2=58.413, P<0.001], the complete resection rate was lower [76.00% (19/25), 93.15% (231/248) VS 100.00% (7/7), χ2=9.497, P=0.009], the curative resection rate was lower than that of differentiated early gastric cancer, but higher than that of undifferentiated early gastric cancer [48.00% (12/25), 89.52% (222/248) VS 42.86% (3/7), χ2=39.757, P<0.001], and the proportion of eCura grade C2 was higher than that of differentiated cancer, but lower than that of undifferentiated cancer [48.00% (12/25), 5.65% (14/248) VS 57.14% (4/7), χ2=58.766, P<0.001]. The results of multivariate analysis showed that the larger lesions ( P=0.004, OR=0.539, 95% CI: 0.354-0.822) was the risk factor for curative resection. In terms of infiltration depth, mucosal ( P=0.001, OR=51.799, 95% CI: 5.535-84.768) and submucosal 1 ( P<0.001, OR=29.301, 95% CI: 24.694-73.972) were protective factors for curative resection compared with submucosal 2. In terms of differentiation degree, compared with mixed type, differentiated type ( P=0.024, OR=3.947, 95% CI: 1.195-13.032) was the protective factor for curative resection, while undifferentiated type ( P=0.443, OR=0.424, 95% CI: 0.048-3.788) showed no difference between curative resection and mixed type. During the follow-up, 7 patients died. The overall survival time was 114.42±0.97 months, and the 5-year survival rate was 97.10%. There was no significant difference in the survival rate of early gastric cancer patients with different degrees of differentiation ( χ2=0.434, P=0.805). The survival rate of early gastric cancer patients with or without curative resection was significantly different ( χ2=4.081, P=0.043). Conclusion:Mixed early gastric cancer patients show high margin positive rate, vascular infiltration, and less curative resection than differentiated early gastric cancer. Therefore, the process of treating mixed early gastric cancer should be more rigorous. The long-term survival prognosis of early gastric cancer after ESD treatment is promising.

The extensive research and application of human gene editing technology have raised many ethical issues,sparking heated debates among scholars.These debates mainly manifest in three aspects,including the limitation of human autonomy in the future,the ambiguity of self-identity,and the intensification of life hierarchy.The root causes of these debates mainly lie in the complexity of the subject's ethical sense of responsibility in the subjective aspect,the negative effects of technology in the objective aspect,and the insufficient external regulations in the social aspect.These issues require the following measures to be taken to resolve,such as enhancing the sense of ethical responsibility of subject,strengthening the internal ethical supervision of human gene editing technology,and establishing an ethical supervision committee and a unified ethical governance framework.
