ObjectiveTo explore the ethical issues and coping strategies in the diagnosis and treatment of 46, XY disorders of sex development （46, XY DSD） under a multidisciplinary team （MDT） model， and to deepen the understanding of relevant ethical issues while accumulating experience. MethodsA retrospective collection was conducted on the data of children with 46, XY disorders of sex development under a single-center MDT model from January 2017 to December 2024， and the ethical issues involved in the diagnosis and treatment process were analyzed. ResultsA total of 24 MDT discussion documents involving 20 children were collected， including 17 with female social gender and 3 with male social gender. The age ranged from 0.5 to 15.8 years， with children under 8 years accounting for 75%. The ethical issues primarily involved how to ensure adequate informed consent， whether surgery was necessary and its timing， and whether gender selection is reasonable and its timing. Among the 10 children raised as females who completed the gender role psychological scale assessment， 5 demonstrated masculine tendencies， all of whom had pathogenic genetic variants. Furthermore， only 1 patient changed the social gender to male. ConclusionThe diagnosis and treatment of 46, XY DSD is relatively complex， requiring multidisciplinary collaboration. This process involves numerous ethical issues and necessitates adhering to medical ethical principles. Ensuring adequate informed consent is crucial， especially for younger children. The surgery and its timing selection must adhere to the principles of beneficence， non-maleficence， and leaving room for the future. Gender selection constitutes a focus and challenge in diagnosis and treatment. Psychological scales and genetic etiologies are conducive to judgments regarding gender selection， yet multiple factors in the real world may interfere with the gender selection.

Depression is a high-incidence mental disorder with complex causes and multifaceted pathogenic mechanisms. Its pathogenesis has not yet been fully elucidated， which has hindered the development of novel and highly effective antidepressant drugs. This condition severely affects human physical and mental health while imposing a significant socio-economic burden. At present， several hypotheses exist regarding the pathogenesis of depression， including monoamine neurotransmitter imbalances， neurotrophic factor deficiencies， neural plasticity impairments， glutamate dysregulation， neuroinflammatory disorders， gut microbiota imbalances， and mitochondrial autophagy dysfunction. Currently， most clinical antidepressants are monoamine neurotransmitter reuptake inhibitors. Although they exhibit certain therapeutic effects， they are associated with significant drawbacks， such as severe adverse reactions and poor patient compliance. In contrast， traditional Chinese medicine （TCM）， characterized by its multi-targeted effects， mild efficacy， and minimal side effects， has demonstrated significant advantages in the treatment of depression. Chinese medicine Polygalae Radix possesses the functions of calming the mind， enhancing cognitive functions， harmonizing the heart and kidneys， and dispelling phlegm to open orifices. It is often included in compound prescriptions for the clinical treatment of depression. Based on current hypotheses regarding the pathogenesis of depression， this paper systematically reviews research progress on the antidepressant mechanisms of Polygalae Radix from multiple perspectives， including its active components， its use in herbal pairings， and its inclusion in TCM compound prescriptions. This review aims to provide a scientific basis for the clinical application of Polygalae Radix in antidepressant therapy and to serve as a reference for the modernization of its antidepressant research.

Objective:To evaluate the clinical equivalence between a domestic calcipotriol/betamethasone dipropionate ointment and the originator product in the treatment of stable plaque psoriasis.Methods:A multicenter, randomized, double-blind, three-arm, parallel-group, active- and placebo-controlled study was conducted, and 449 patients aged 18 - 65 years with stable plaque psoriasis were enrolled from 25 hospitals (such as the First Affiliated Hospital of China Medical University). Eligible patients had a baseline physician's global assessment (PGA) score of ≥ 3 points, baseline body surface area (BSA) involvement of 5% - 30%, and a target lesion psoriasis area and severity index (TL-PASI) for plaque elevation of ≥ 3 points. Participants were randomly assigned in a 2:2:1 ratio to the test group ( n = 179), reference group ( n = 180), and placebo group ( n = 90), and applied the domestic calcipotriol/betamethasone dipropionate ointment, originator product, and ointment base respectively, once daily in the evening for 4 weeks. Efficacy and safety were assessed at weeks 1, 2, and 4. The primary efficacy endpoints were the treatment success rates and clinical success rates in each group at week 4. The per-protocol set (PPS) was used for the primary efficacy analysis, and the intention-to-treat (ITT) set for supplementary efficacy analysis. Equivalence between the test and reference preparations was tested using the Cochran-Mantel-Haenszel method adjusted for randomization strata. Superiority of the test and reference preparations over the placebo was also tested. Measurement data were compared among the 3 groups using analysis of variance or non-parametric tests, while treatment success rates, clinical success rates, and incidence rates of adverse reactions were compared using the chi-square test. Results:The ITT, PPS, and safety sets included 447, 420, and 448 patients, respectively. In the ITT set, patients were aged 43.6 ± 12.8 years, including 320 (71.6%) males and 127 (28.4%) females, and the disease duration was 11.21 ± 9.05 years; 316 (70.7%) had a PGA score of 3 points and 131 (29.3%) had a PGA score of 4 - 5 points. No significant differences in the baseline characteristics (including age, sex, disease duration and disease severity) were observed among the 3 groups (all P > 0.05). Based on the PPS analysis, the treatment success rates were 57.9% (99/171) in the test group, 50.3% (86/171) in the reference group, and 7.7% (6/78) in the placebo group, and the clinical success rates were 57.9% (99/171), 50.3% (86/171), and 10.3% (8/78), respectively; both the test and reference groups were superior to the placebo group in both treatment and clinical success rates (all P < 0.001) ; the rate differences for treatment success (90% confidence interval [ CI]: -1.3% - 16.4%) and clinical success (90% CI: -1.3% - 16.3%) between the test and reference groups were entirely within the pre-defined equivalence margin (-20% - 20%). Subgroup analyses by baseline PGA scores: for patients with a baseline PGA score of 3 points, the treatment success rates in the test, reference, and placebo groups were 60.8% (73/120), 52.1% (62/119), and 11.1% (6/54), respectively, and the corresponding clinical success rates were 61.7% (74/120), 53.8% (64/119), and 13% (7/54), respectively; the test and reference groups did not differ significantly in treatment or clinical success rates (both P > 0.05), but both showed higher success rates than the placebo group (all P < 0.001) ; the results of statistical comparisons among the 3 groups in patients with a baseline PGA score of 4 - 5 points were consistent with those observed in patients with a baseline PGA score of 3 points. The percentage reductions in PGA and TL-PASI scores from baseline to weeks 1, 2, and 4 showed significant differences among the 3 groups, which were significantly higher in the test and reference groups than in the placebo group (all P < 0.001), but did not differ between the test and reference groups (all P > 0.05). The primary adverse reactions were local skin reactions, such as pruritus, pain, and erythema. The incidence rates of adverse reactions were 8.9% (16/179) in the test group, 7.3% (13/179) in the reference group, and 7.8% (7/90) in the placebo group, with no significant difference among the 3 groups ( P > 0.05) . Conclusions:The domestic calcipotriol/betamethasone dipropionate ointment demonstrated clinical equivalence to the originator product in the treatment of stable plaque psoriasis, and the two agents exhibited comparable efficacy for patients with varying degrees of disease severity, and were comparable in the speed and degree of clinical improvement, with similar favorable safety profiles.

We report the clinical course from birth to adolescence of a patient carrying a compound heterozygous variation in the ectonucleotide pyrophosphatase/phosphodiesterase family member 1(ENPP1) gene. The patient was diagnosed with generalized arterial calcification of infancy shortly after birth, and subsequently with autosomal recessive hypophosphatemic rickets type 2 at the age of 11 years. Following effective blood pressure control, treatment with neutral phosphate, calcitriol, and vitamin D was initiated. During follow-up, no progression of vascular calcification was observed. Through this case report and a review of relevant literature, we aim to enhance clinicians′ understanding of this rare condition.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods. The findings provide references for optimizing human-monkey conflict management and the prevention and control of zoonotic diseases in urban ecological parks.

With the rapid evolution of medical information technology, internet hospitals had become an integral part of China′s healthcare service system and could play a unique role in multidisciplinary diagnosis and treatment (MDT). In 2023, Nanjing Drum Tower Hospital built a smart service platform for MDT based on its internet hospital under the design concept of " global collaboration, process re-engineering, and smart empowerment", and officially launched in November of the same year. The platform included a five-tier architectur: user interaction, application services, data management, system integration and infrastructure, and embeds functional modules such as consultation management, an AI-assisted engine and a workflow engine. This platform covered Nanjing Drum Tower Hospital Group members, implemented an online-offline integrated, end-to-end workflow (pre-intra-post consultation). It realized the integration and utilization of high-quality medical resources across regions and institutions, and improved the quality and efficiency of MDT. As of December 2024, the platform had covered 30 specialties and completed 75 MDT consultations. The consultation cycle had been shortened from the traditional MDT mode of 14.2 days to 2.4 days, effectively reducing the number of patients traveling to and from the hospital. This platform had expanded the business scope of internet hospitals, improved the utilization rate of medical resources, and could provide references for other public hospitals in China to optimize the MDT service mode.

Objective:To explore the impact of Epstein-Barr Virus(EBV) infection on treatment response and survival in newly diagnosed multiple myeloma(MM).Methods:The clinical data of 196 patients with newly diagnosed MM admitted to Zhongshan Hospital of Fudan University from June 1st, 2019 to February 25th,2021 were analyzed retrospectively and divided into EBV-positive group (106 cases) and negative group (90 cases) according to the primary EBV DNA results in peripheral blood mononuclear cells.To analyse the distribution of EBV positive rates in each type and in each stage of the Revised International Staging System (R-ISS), and to compare EBV DNA loads in EBV-positive patients among R-ISS stages.Rank sum test, 2×2 chi-square test and independent sample t-test were used to compare laboratory findings, such as liver and kidney function, immunohistochemistry and cytogenetics, treatment efficacy and survival prognosis between the two groups.The clinical prognosis of EBV-positive patients was summarized through survival analysis and Cox regression.Results:The EBV positive rate in patients with newly diagnosed MM was 54% (106/196), with the highest rate in patients with κ light chain type (9/12).Patients with R-ISS stage Ⅲ had a significantly higher positive rate than with stage Ⅰ ( χ2=4.68, P=0.031) and stage Ⅱ ( χ2=6.04, P=0.014), but there was no significant difference in EBV DNA loads between EBV-positive MM patients by stage ( Z=3.27, P=0.195).Serum creatinine (Scr) and β 2-microglobulin (β 2-MG) levels were higher in the EBV-positive group than in the EBV-negative group ( Z=1.98, P=0.048 and Z=2.08, P=0.038), and the occurrence of t(4;14) was also higher in the EBV-positive group ( χ2=3.93, P=0.047).The proportion of complete response (CR)/stringent complete response(sCR) and very good partial response(VGPR) after completion of the fourth chemotherapy were significantly lower in the EBV-positive group than in the EBV-negative group ( χ2=12.82, P=0.001 and χ2=8.30, P=0.004), and a higher rate of progressive disease (PD) occurred in the EBV-positive group ( χ2=4.48, P=0.046).The 2-year progression-free survival (PFS) of MM patients was shorter in the EBV-positive group compared to that in the EBV-negative group ( Z=-4.50, P0.01).Cox regression analysis showed that R-ISS stage Ⅲ ( HR=5.38, 95% CI 1.28-22.56, P=0.021), failure to achieve VGPR after the fourth chemotherapy ( HR=3.02, 95% CI 1.42-6.46, P=0.004), EBV-positive ( HR=1.98, 95% CI 1.02-3.87, P=0.045), with 1q21 amplification ( HR=2.35, 95% CI 1.16-4.75, P=0.017) and 13q14 deletion ( HR=1.93, 95% CI 1.01-3.67, P=0.046) were independent risk factors for PFS in newly diagnosed MM. Conclusions:EBV infection is an independent risk factor for poor prognosis, which has important clinical implications for the outcome and prognosis of patients with newly diagnosed MM, and may become a novel clinical assessment indicator.

Objective:To explore the adverse reactions and its risk factors during bowel preparation prior to colonoscopy.Methods:The clinical data of 1 727 patients who underwent colonoscopy at the First Affiliated Hospital of Air Military Medical University from September 2019 to March 2021 were analyzed retrospectively. The primary endpoint was the incidence of adverse reactions during bowel preparation. The risk factors of adverse reactions were identified by logistic regressions.Results:The incidence of overall adverse reactions was 54.9% (948/1 727). The incidences of nausea, vomiting, and abdominal discomfort were 38.6% (666/1 727) , 10.2% (177/1 727), 25.9% (447/1 727), respectively. Multivariate logistic regression analysis showed that being female ( OR=1.77, 95% CI: 1.45-2.17, P<0.001), history of abdominal surgery ( OR=1.38, 95% CI:1.08-1.75, P=0.009), inflammatory bowel disease ( OR=1.77, 95% CI: 1.08-2.91, P=0.024) were independent risk factors for adverse reactions during bowel preparation. Female gender ( OR=2.37, 95% CI: 1.66-3.38, P=0.001) and history of abdominal or pelvic surgery ( OR=1.45, 95% CI: 1.02-2.06, P=0.038) were independent risk factors for vomiting, while body mass index ≥25 kg/㎡( OR=0.48, 95% CI: 0.28-0.80, P=0.005) and age≥60 years ( OR=0.58, 95% CI: 0.38-0.89, P=0.013) were protective factors for vomiting during bowel preparation. Conclusion:A significant portion of patients experience adverse reactions during bowel preparation for colonoscopy. The risk factors of adverse reactions include female, history of abdominal surgery and inflammatory bowel disease. Female and a history of abdominal surgery are independent risk factors for vomiting, while obesity and old age are protective factors for vomiting during bowel preparation.

Objective To investigate the effect of local histopathological changes of thyroid nodules after ultrasound-guided fine needle aspiration biopsy(US-FNBA)on laparoscopic thyroid surgery.Methods The clinical data of 120 patients with thyroid malignant tumors admitted to Xiaogan Hospital of Wuhan University of Science and Technology from January 2020 to December 2022 were retrospectively analyzed,and according to whether received US-FNAB before surgery they were divided into the observation group(with US-FNAB)and the control group(without US-FNAB),with 60 cases in each group.The operation time,change of parathyroid hormone(ΔPTH)before and after surgery,change of serum Ca2+concentration(serum ΔCa2+)before and after surgery,drainage volume 24 hours after surgery and incidence of complications were compared between the two groups.According to fine needle aspiration-to-surgery(FTS),the patients in the observation group were further divided into the group A(FTS≤3 days)and the group B(FTS>3 days),and the effect of US-FNAB on laparoscopic thyroid surgery was explored combined with the pathological changes of the thyroid puncture capsule of the two groups.Results The operation time of the observation group was longer than that of the control group(P<0.05),and there was no significant difference in the drainage volume 24 hours after surgery,ΔPTH,serum ΔCa2+,or proportions of facial or limb numbness,hypoparathyroidism,recurrent laryngeal nerve integrity,and hypocalcemia between the two groups(P>0.05).There was no significant difference in the operation time,ΔPTH,serum ΔCa2+,drainage volume 24 hours after surgery,hypocalcemia,recurrent laryngeal nerve integrity or hypothyroidism between the group A and group B(P>0.05).The proportion of patients with facial or limb numbness after surgery in the group A was significantly lower than that in the group B(P<0.05).Conclusion Preoperative US-FNAB for thyroid nodules may prolong the operation time in patients undergoing laparoscopic thyroid surgery,and surgical treatment in early aspiration can help decrease this effect and reduce the incidences of postoperative hypocalcemia and hypothyroidism.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.
