Based on the view that wind pathogen runs through the entire course of the occurrence and development of nephrotic syndrome， it is proposed that the core pathogenesis of refractory nephrotic syndrome （RNS） in children involves imbalance of the lung， spleen， and kidney， invasion of wind pathogen， and stagnation of turbidity and stasis， and that directing the turbid downward with wind medicinals is the key therapeutic strategy. In clinical practice， according to the distinct pathogenic characteristics of three patterns， including defensive qi insecurity of the lung， yang deficiency with loss of regulation， and binding of turbidity and stasis， three corresponding methods are applied， which are diffusing the lung to consolidate defensive qi， elevating yang to supplement the spleen and kidney， and activating blood to unblock turbidity and stasis. For the pattern of defensive qi insecurity of the lung， wind medicinals are used to penetrate and disperse external pathogens， such as fangfeng （Radix Saposhnikoviae） and mahuang （Herba Ephedrae） for diffusing the lung， dispersing wind， and consolidating defensive qi. For yang deficiency with loss of regulation pattern， wind medicinals are employed to elevate yang and assist transformation， such as shengma （Rhizoma Cimicifugae） and gegen （Radix Puerariae Lobatae） for raising clear yang， warming and activating the spleen and kidney. For binding of turbidity and stasis pattern， wind medicinals with scurrying and collateral‑unblocking properties are used， such as jixueteng （Caulis Spatholobi）， luoshiteng （Caulis Trachelospermi）， and chuanshanlong （Rhizoma Dioscoreae Nipponicae） for dispelling wind， activating blood， resolving stasis， and directing turbidity downward. In all these methods， the core principle is to use wind medicinals to regulate qi movement， open and unblock the sweat pores， and separately eliminate turbid pathogens， thereby providing a theoretical and practical basis for the traditional Chinese medicine diagnosis and treatment of RNS in children.

ObjectiveTo summarize the incidence and clinical features of drug hypersensitivity reactions in children treated with sustained-releasing gonadotropin-releasing hormone agonists （GnRHa）， aiming to provide guidance for the safe clinical application of GnRHa in children. MethodsThe medical data of children diagnosed with central precocious puberty （CPP） or early and fast puberty （EFP） were retrospectively analyzed， who received GnRHa treatment at the Children's Growth Center of the First Affiliated Hospital of Sun Yat-sen University between January 1990 and July 2023. The occurrence of GnRHa-related drug hypersensitivity reactions were summarized， including the incidence and clinical features of systemic reactions and sterile abscesses. ResultsAmong the 1 684 children treated with GnRHa for CPP/EFP， the female-to-male ratio was 3.8∶1. A total of nine children （0.53%） developed 44 occurrences of drug hypersensitivity reactions. Four children （0.24%） presented with sterile abscesses （21 occurrences）， and five children （0.30%） experienced systemic hypersensitivity reactions （14 occurrences）. Four children were hypersensitive to triptorelin acetate， three were hypersensitive to leuprorelin acetate， and two were hypersensitive to both triptorelin acetate and leuprorelin acetate. The predominant hypersensitivity reactions to leuprorelin acetate were sterile abscesses， observed in four cases （4/277， 1.44%）， whereas the main reactions to triptorelin acetate were systemic hypersensitivity reactions， affecting five cases （5/1 501， 0.33%）. Case one presented with a severe and complex condition， exhibiting hypersensitivity to multiple GnRHa preparations （sustained-releasing triptorelin， sustained-releasing leuprorelin， and short-acting triptorelin）， and presenting with diverse manifestations， including induration， sterile abscesses， systemic hypersensitivity reactions， and even loss of suppression of the hypothalamic-pituitary-gonadal axis， leading to treatment failure. ConclusionsThe proportion of children experiencing drug hypersensitivity reactions to sustained-releasing GnRHa is relatively low at 0.53%， with diverse manifestations. The reactions primarily manifest as sterile abscesses and systemic hypersensitivity reactions， and in severe cases， may lead to treatment failure due to loss of suppression of the hypothalamic-pituitary-gonadal axis.

Objective: To investigate the efficacy of implantable neuromuscular electrical stimulation system on stress urinary incontinence (SUI) model in female rats. Methods: A total of 21 female infertile SD rats were randomly divided into the control，sham stimulation，and stimulation groups，with 7 rats in each group.All rats received vaginal dilation (VD) to simulate postpartum SUI.One week after VD，the control group was given normal feeding，stimulators were implanted in the pelvic floor muscles of the sham stimulation and stimulation groups.The sham stimulation group received normal feeding for 2 weeks，and the stimulation group received pelvic floor electrical stimulation (PFES) for 2 consecutive weeks.The leak point pressure (LPP) of each rat was measured with cystometry before VD (baseline value)，1 week after VD，and 2 weeks after PFES. Results: In the control group and sham stimulation group，LPP increased after 2 weeks of treatment compared with that after 1 week of VD，but it still did not return to the baseline level (P<0.001).In the stimulation group，after 2 consecutive weeks of PFES，LPP increased significantly compared with that 1 week after VD，and returned to the baseline value (P>0.05).There was no significant difference in the LPP baseline values and levels after 1 week of VD among the 3 groups (P>0.05).The LPP in the stimulation group after 2 weeks of PFES was significantly higher than that in the sham stimulation group and stimulation group (P<0.001). Conclusion: The implantable neuromuscular electrical stimulation system is effective in short-term intervention of SUI in female rats，the further studies are needed to confirm the long-term efficacy and safety of the system，the optimal stimulation sites，optimal stimulation parameters，and potential mechanisms of action.

Objective: To evaluates the association between maternal overweight/obesity during pregnancy and offspring risk of metabolic dysfunction associated steatotic liver disease (MASLD), providing theoretical evidence for early life MASLD prevention. Methods: An online search was conducted across ten databases (CNKI, Wanfang, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, PROSPERO, PQDT Global, ScienceDirect) for research literature on the association between maternal overweight/obesity during pregnancy and the development of MASLD in offspring, with the search period spanning from January 2014 to December 2024. Two researchers independently screened literature, extracted data, and assessed study quality. Statistical analysis was performed using R 4.3.3. Results: Ten studies involving 10 229 participants were included, comprising 4 cohort studies and 6 case control studies. Cohort studies showed that maternal overweight and obesity significantly increased offspring MASLD risk ( RR=1.59, 95%CI=1.06-2.39, P <0.05), with moderate heterogeneity ( I 2=56.9%, P =0.07). Case control studies indicated a positive association between maternal overweight/obesity during pregnancy and offspring risk of MASLD( OR=2.00, 95%CI=1.68-2.39, P < 0.05), with low heterogeneity ( I 2=48.8%, P =0.08). Conclusions Maternal overweight/obesity during pregnancy positively correlates with offspring MASLD risk. Gestational weight management may reduce the risk.

OBJECTIVE To analyze the influencing factors of voriconazole trough concentration and adverse drug reactions （ADR） in renal transplant recipients. METHODS Data from inpatients who received voriconazole and therapeutic drug monitoring in our hospital between January 2022 and August 2023 were retrospectively analyzed. Patients were divided into renal transplant group and non-renal transplant group based on transplantation status. A 1∶1 propensity score matching （PSM） method was used to balance differences in baselines between the two groups. Voriconazole trough concentrations， target attainment rate， clinical efficacy， and ADR were compared between the two groups. Multiple linear regression （backward） was used to analyze the factors influencing voriconazole trough concentrations in the renal transplant group. Univariate analysis and binary Logistic regression were used to identify independent risk factors for ADR in the renal transplant group. RESULTS After PSM， 48 patients were included in each group. There were no statistically significant differences in the mean voriconazole trough concentration， target attainment rate or efficacy rate between the two groups （P＞0.05）. The total incidence of ADR was significantly higher in the renal transplant group than in the non-renal transplant group （P＜0.05）. Multiple linear regression analysis showed that age， average daily dose， pulmonary infection， total bilirubin during medication， day-1 loading dose， use of the original drug， concomitant immunosuppressant use， and the occurrence of ADR were factors influencing voriconazole trough concentration in renal transplant patients （P＜0.05）. Binary Logistic regression analysis showed that abnormal direct bilirubin during medication [OR＝7.747， 95%CI （1.334， 45.005）， P＝0.023] was an independent risk factor for ADR in renal transplant patients receiving voriconazole. CONCLUSIONS Age， average daily dose， pulmonary infection， use of the original drug， day-1 loading dose， total bilirubin during medication， concomitant immunosuppressant use， and the occurrence of ADR are the factors influencing voriconazole trough concentration in renal transplant patients. Furthermore， patients with abnormal direct bilirubin during medication are more susceptible to ADR.

Objective:To investigate the efficacy of radiotherapy in patients with advanced esophageal cancer receiving first-line chemoimmunotherapy.Methods:A retrospective analysis was conducted on the data of 137 patients with Stage Ⅳ esophageal squamous cell carcinoma (ESCC) treated at our hospital from January 2018 to May 2023. These patients were divided into two groups: a group treated with first-line chemoimmunotherapy combined with radiotherapy (chemoimmunotherapy + radiotherapy group, n = 43) and a group treated with only chemoimmunotherapy ( n = 94). Inverse probability of treatment weighting (IPTW) was applied to balance baseline characteristics between the groups. With overall survival (OS) and progression-free survival (PFS) as study endpoints, the survival data were analyzed using the Kaplan-Meier method, the log-rank test, and the Cox regression method. Results:Before calibration, the chemoimmunotherapy + radiotherapy group significantly outperformed the sole chemoimmunotherapy group in median PFS (13.6 months vs. 7.0 months; HR: 0.501, 95% CI: 0.309-0.811, P = 0.005). After calibration using the COX proportional-hazards model for age, gender, Eastern Cooperative Oncology Group (ECOG) performance status, smoking history, T/N/M stage, and tumor location, the chemoimmunotherapy + radiotherapy group still had significant advantages in PFS (14.7 months vs. 7.0 months; HR: 0.441, 95% CI: 0.261-0.745, P = 0.002). IPTW analysis further confirmed this trend (13.9 months vs. 7.0 months; HR: 0.492, 95% CI: 0.304-0.795, P < 0.001). Specifically, the median OS of the chemoimmunotherapy + radiotherapy group demonstrated significant improvement in all analyses: pre-calibration (29.5 months vs. 18.0 months; HR: 0.507, 95% CI: 0.297-0.867, P = 0.013), after calibration using the Cox model (27.5 months vs. 16.7 months; HR: 0.470, 95% CI: 0.266-0.830, P = 0.009), and after calibration using IPTW (29.5 months vs. 16.9 months; HR: 0.448, 95% CI: 0.262-0.764, P < 0.001). Conclusions:The combination of radiotherapy and first-line chemoimmunotherapy can significantly improve survival outcomes of patients with advanced ESCC, suggesting its potential as a standard treatment strategy.

Objective This study conducted a dynamic network analysis of the symptoms in patients with hepatocellular carcinoma(HCC)at different postoperative time points,aiming to explore evolving core symptoms and provide a basis for developing precise clinical symptom management programs.Methods A longitudinal study was carried out involving 370 HCC patients who underwent surgical treatment at a hospital in Kunming city between February and December 2024.Questionnaires were administered on postoperative day 2(T1)and day 7(T2),using the Chinese version of the Memory Symptom Assessment Scale.Symptom networks of 18 symptoms were constructed for both time points using R software to explore core symptoms and their interconnections.A network comparison test was also performed to assess differences between the 2 time points.Results All 370 patients completed the questionnaire at T1,and 357 valid responses were collected at T2,yielding a response rate of 96.49％.At T1,"feeling nervous"had the highest centrality(rs=1.29),while at T2,"feeling sad"was most central(rs=1.11).Overall strength of the symptom networks showed that notable changes were observed in the edge weights between symptoms(P=0.01).Conclusion While the overall structure of early postoperative symptoms in HCC patients remained relatively stable over time,the core symptoms shifted."Feeling nervous"emerged as the central symptom at T1,whereas"feeling sad"became predominant.Digestive-related symptoms are progressively more closely linked over time.Healthcare professionals should dynamically assess patients' early postoperative psychological symptoms and digestive system related symptoms,and focus on intervening with symptoms of tension and sadness.

Objective:To analyze the clinical characteristics and gene mutations of 4 patients with the male phenotype of 17α-hydroxylase /17, 20-lyase deficiency(17-OHD), in order to improve the recognition and appropriate management of atypical cases.Methods:A retrospective analysis was performed on the clinical features, biochemical findings, and gene mutations of 4 patients with the male phenotype of 17-OHD treated in our hospital between 2018 and 2023.Results:The social gender of all 4 patients with 17-OHD was male. None of the 4 patients had hypertension or hypokalemia, but all had micropenis and gynecomastia. Two patients had adrenal hyperplasia, while adrenal morphology was normal in the other two. One patient had decreased bone mass. There were typical changes in the steroid synthesis-related hormone spectrum: progesterone was significantly elevated in all 4 patients, 17-hydroxyprogesterone was not markedly abnormal, cortisol, dehydroepiandrosterone sulfate(DHEAS) and estradiol levels were low, and testosterone levels were also low.Conclusion:17-OHD is a rare type of congenital adrenal hyperplasia, with the male phenotype being even rarer. Early symptoms are often atypical, resulting in high rates of misdiagnosis and missed diagnosis. Patients without hypertension and hypokalemia are particularly prone to diagnostic confusion. Male patients with unexplained progesterone elevation, poor secondary sexual development, and gynecomastia should undergo timely steroid hormone profiling and genetic testing to avoid misdiagnosis and missed diagnosis.

Objective:To validate and optimize the interpretation methods and cut-off values of prolonged activated partial thromboplastin time (APTT) mixing test, in order to elevate the clinical applicational value in differentiating single factor deficiency, positive lupus anticoagulant (LA) and FⅧ inhibitors.Methods:This cross-sectional retrospective study involved 130 cases with single APTT prolongation for unknown reasons who underwent mixing tests in the First Hospital of Jilin University from January 1st, 2022 to December 31st, 2023, including 84 males and 46 females. Rosner index (RI), Percentage correction ("Chang") method, Normal reference interval (NRI) method, differential analysis, post-incubation prolongation time and percentage (including mixed immediately and ) were respectively calculated and analyzed for both immediate mixing and 2-hour post-mixing incubation. According to clinical diagnosis, patients were divided into single factor deficiency (51 cases), positive lupus anticoagulant (LA) (56 cases), and positive factor Ⅷ (FⅧ) inhibitor (23 cases). Receiver operation characteristic (ROC) curve analysis was used to determine the cut-off values for APTT mixing test methods in patients with different reasons for prolonged APTT, which were evaluted and adjusted by AUC, sensitivity, and specificity, and compared with the methods currently used for interpretations.Results:For the single factor deficiency cases, the AUCs of immediate RI index <7.5% and incubated RI index <13.9% were 0.87 and 0.90, respectively, with sensitivities at 87.8% and 83.8%, and specificities at 72.0% and 80.0%, whose combination had sensitivity and specificity at 87.3%, and 94.0%, respectively; the judging accuracy increased from 84.6% (110/130) in currently used rule to 93.1% (121/130). For the positive lupus anticoagulant (LA) cases, the combination of immediate RI index >10.3% and prolonged post-incubation clotting time percentage <9.1% showed 88.5% sensitivity and 99.8% specificity; the judging accuracy improved from 80.0% (104/130) in currently used rule to 86.2% (112/130). For positive FⅧ inhibitor cases, the combination of incubated RI index >17.0% and prolonged post-incubation clotting time percentage >9.1% had 99.8% sensitivity and 100.0% specificity; the judging accuracy increased from 89.2% (116/130) in currently used rule to 94.6% (123/130).Conclusion:This study validated and optimized the interpretation methods and cut-off values for the prolonged APTT mixing test in differentiating single factor deficiencies, prositive FⅧ inhibitors and LA positive cases, significantly improving the judging sensitivity and specificity.
