ObjectiveTo evaluate the efficacy of immediate postoperative oral administration of 2 mg estradiol/estradiol dydrogesterone tablets in reducing secondary surgery for retainedproducts of conception（RPOC）， preventing intrauterine adhesions（IUA）， and promoting endometrial repair following induced abortion. MethodsA retrospective analysis was conducted on 494 patients who underwent induced abortion. The control group （n=214） received conventional postoperative treatment with antibiotics and Yimucao granules， while the observation group （n=280） received immediate administration of estradiol/dydrogesterone tablets （each tablet contains 2 mg of estradiol），combined with antibiotics and Yimucao granules. The two groups were compared for the secondary surgery rate for RPOC， incidence of IUA， endometrial thickness at 2 weeks postoperatively， duration of postoperative vaginal bleeding， time to menstrual resumption， incidence of reduced menstrual volume after resumption， and postoperative complications （pelvic infection， intrauterine fluid accumulation）. ResultsThe observation group showed a lower rate of secondary surgery for RPOC compared to the control group （0.4% vs 2.3%）， but the difference was not statistically significant （P=0.13， Fisher’s exact test）. The observation group also had a significantly lower incidence of IUA （P<0.05）， greater postoperative endometrial thickness at 2 weeks （P<0.05）， and significantly shorter duration of postoperative vaginal bleeding and time to menstrual resumption. The incidence of reduced menstrual volume postoperatively and complications （pelvic infection， intrauterine fluid accumulation） were also significantly lower in the observation group （all P<0.05）. ConclusionImmediate oral administration of estradiol/dydrogesterone tablets after induced abortion significantly prevents intrauterine adhesions， shortens postoperative vaginal bleeding duration， promotes endometrial repair， improves menstrual recovery， and potentially reduces the risk of secondary surgery for retained products of conception.

Although percutaneous pulmonary artery denervation (PADN) has demonstrated long-term benefits in combined post- and pre-capillary pulmonary hypertension, its usefulness for isolated post-capillary pulmonary hypertension (IpcPH) remains unclear. This report presents 2 cases of IpcPH due to left heart failure who underwent PADN treatment following an insufficient response to optimized conventional therapy. This case study illustrates how PADN, when combined with heart failure guideline-directed medical therapy, may represent a promising treatment option for IpcPH.

Objective:To analyze the relationships among sense of coherence, social avoidance and distress, and severity of depressive symptoms in adolescent patients with depression.Methods:A total of 98 adolescent patients with depression hospitalized at the Affiliated Mental Health Center of Zhejiang University School of Medicine (Hangzhou Seventh People's Hospital) from June 2023 to January 2024 were selected by convenience sampling. The Center for Epidemiologic Studies Depression Scale (CES-D), the Sense of Coherence Scale-13 (SOC-13), and the Social Avoidance and Distress Scale (SADS) were used for assessment. Pearson correlation analysis was conducted to examine the correlations among severity of depressive symptoms, sense of coherence, and social avoidance and distress. A structural equation model was established using AMOS 23.0 software, and the mediating effect was verified by the percentile Bootstrap method with the PROCESS macro.Results:The CES-D total score of the 98 patients was (22.36±1.75) ; the SOC-13 total score was (55.02±3.38), with the highest dimension score in manageability (mean 4.38±0.52 per item). The SADS total score was (19.40±1.39), including a score of (10.26±0.98) for social avoidance and (9.14±1.01) for social distress. Pearson correlation analysis indicated that CES-D total score was negatively correlated with SOC-13 total score and positively correlated with SADS total score ( P<0.05). Mediation analysis showed that social avoidance and distress partially mediated the relationship between sense of coherence and severity of depressive symptoms in adolescents with depression, with a mediation effect value of -0.333, accounting for 62.95% of the total effect (-0.333/-0.529) . Conclusions:Adolescent patients with depression had a generally low level of sense of coherence and a high level of social avoidance and distress. Sense of coherence was negatively correlated with social avoidance and distress.

Objective:To evaluate the advantages and short-term clinical effects of totally robotic Nissen 360° fundoplication compared with laparoscopic surgery.Methods:A retrospective analysis was conducted on data of 110 patients undergoing Nissen 360° fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Aug 2024. Among them, 50 cases underwent totally robotic fundoplication, and 60 cases underwent laparoscopic fundoplication. By comparing and analyzing the fatigue level of the primary surgeon during the operations, postoperative incisional pain in patients, swallowing function recovery and the time to resume a normal solid-food diet within 3 months post-surgery, the advantages of totally robotic surgery were evaluated. Additionally, by examining the postoperative recovery of reflux symptoms, postoperative patient comfort, and satisfaction levels in both groups, the short-term clinical outcomes of totally robotic surgery were assessed.Results:Both groups of patients successfully completed the surgeries without any intraoperative or postoperative complications occurring. The fatigue score of the primary surgeon in the totally robotic group was significantly better than that in the laparoscopic group[ (2.34±1.38) vs. (2.89±1.51), t=1.385, P<0.01]. The time taken to resume a normal solid-food diet postoperatively in the totally robotic group was significantly shorter than that in the laparoscopic group[ (27.90±6.77) d vs. (40.78±13.60) d, t =5.765, P<0.01]. Moreover, the postoperative pain comfort level was better in the robotic group than in the laparoscopic group [(1.65±0.72) points vs. (2.23±0.59) points, t=3.742, P<0.01]. Within 12 months postoperatively, the GERD-Q scores in the totally robotic group decreased significantly, and reflux symptoms disappeared, comparable to that in the laparoscopic group. Conclusions:The totally robotic Nissen 360° fundoplication leads to lower fatigue levels for the surgeon. Patients experience significant advantages in terms of postoperative pain perception and dietary recovery. Additionally, it demonstrates excellent postoperative anti-reflux efficacy, high patient comfort, and the surgery is safe and reliable.

The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

Objective To explore the differences in the use of hypoglycemic drugs and glycated hemoglobin(HbA1c)levels among elderly patients with type 2 diabetes mellitus(T2DM)of different age groups,and to provide some references for individualized blood glucose control in elderly T2DM patients.Methods A retrospective study was conducted.A total of 187 elderly(≥70 years old)T2DM patients admitted to Guangdong Provincial People's Hospital from October 2022 to August 2024 were selected as the research subjects.The patients were divided into three groups according to age:70-79(93 cases),80-89(52 cases),and≥90(42 cases)years old.The differences in glucose metabolism,lipid metabolism,renal function and the use of hypoglycemic drugs among the groups were compared.Results With increasing age,the hospital stays for the 70-79,80-89,and≥90 years old groups significantly increased(days:7.78±2.84,10.17±7.97,15.45±11.21,P<0.05),diastolic blood pressure gradually decreased[mmHg(1 mmHg≈ 0.133 kPa):75.60±9.15,73.77±10.79,67.45±9.50],estimated glomerular filtration rate(eGFR)and HbA1c both significantly decreased[eGFR(mL·min-1·1.73 m-2):65.55±23.01,49.68±20.19,46.39±16.41;HbA1c(9.02±1.99)%,(8.75±2.21)%,(7.80±1.43)%,all P<0.05].In terms of hypoglycemic treatment,the average number of hypoglycemic drugs used by the≥90 years old group was significantly less than that of the 80-89 years old group and the 70-79 years old group(types:1.86±0.78 vs.2.67±1.12,2.88±0.93,both P<0.01).With increasing age,the usage rates of sodium-glucose cotransporter 2 inhibitors(SGLT-2i)and metformin(MET)in the 70-79,80-89,and≥90 years old groups gradually decreased[SGLT-2i:50.54%(47/93),42.31%(22/52),26.19%(11/42),MET:46.24%(43/93),30.77%(16/52),7.14%(3/42),all P<0.05].Conclusions Medical workers have fully considered factors such as renal function,diabetic cardiovascular complications,health status,and life expectancy in the use of hypoglycemic drugs for elderly T2DM patients and have implemented individualized blood glucose management.However,in the≥90 years old group,the HbA1c level is too strict,and the risk of hypoglycemia should be carefully prevented.

There is a certain correlation between the color of powder and the content of moisture, alcohol-soluble extractives and ginsenosides.

Immune thrombocytopenia (ITP) is a hemorrhagic autoimmune disease characterized by antibody-mediated platelet injury. ITP has complicated immunopathological mechanisms that need further elucidation. It is well known that the costimulatory molecules OX40 ligand (OX40L) and OX40 play essential roles in the immunological mechanisms of autoimmune diseases. Previously, we discovered that the expression of OX40L and OX40 is significantly increased in the peripheral blood mononuclear cells (PBMCs) of ITP patients. In our present study, OX40L-induced follicular helper T (Tfh) cells exhibited an activated phenotype with elevated expression of inducible T-cell costimulator (ICOS), programmed cell death protein-1 (PD-1), and cluster of differentiation 40 ligand (CD40L) in vitro. Moreover, aberrant OX40L‒OX40 expression might promote the Tfh1-to-Tfh2 shift in vivo, inducing the generation of autoantibodies by enhancing the helper function of Tfh cells for B lymphocytes in a mouse model, which might accelerate the progression of ITP. Additionally, signal transduction through the OX40L‒OX40 axis might be related to the activation of tumor necrosis factor receptor-associated factor (TRAF)‒nuclear factor-κB (NF-κB) and Janus kinase (JAK)‒signal transducer and activator of transcription (STAT) signaling pathways. Overall, OX40L‒OX40 signaling is proposed as a potential novel therapeutic target for ITP.
