OBJECTIVE To establish the graded management standards for off-label use of Shenqi fuzheng injection. METHODS Systematic searches were conducted in databases including CNKI, PubMed and the Cochrane Library to retrieve guidelines/consensuses, systematic reviews/meta-analyses, and randomized controlled trials (RCTs) of Shenqi fuzheng injection. The quality of evidence was evaluated using AGREE Ⅱ, AMSTAR Ⅱ, and the Risk of Bias 1.0 tool recommended by Cochrane Collaboration, and the graded management standard for off-label use of Shenqi fuzheng injection was developed by using the Thomson grading system. RESULTS A total of 534 articles were involved, including 11 guidelines, 22 systematic reviews/meta-analysis, and 501 RCTs. They covered 79 off-label indications for Shenqi fuzheng injection: cancer-related fatigue, colorectal cancer and breast cancer, all with high-quality evidence were classified under grade A management (grade Ⅰ commendation), allowing all physicians across the hospital to prescribe relevant treatments; five diseases, such as ovarian cancer, liver cancer, leukemia, heart failure and cerebral infarction, were classified under grade B management (grade Ⅱa commendation), with prescription restricted to physicians with intermediate or higher professional titles in specific departments; eleven diseases, including sepsis, cervical cancer, esophageal cancer, etc., were classified under grade C management (grade Ⅱb commendation), requiring strict evaluation by senior physicians before prescription; the use of Shenqi fuzheng injection for other conditions was explicitly prohibited due to a lack of sufficient evidence. CONCLUSIONS Off-label use of Shenqi fuzheng injection is prevalent. The graded management standard established by evidence-based medical approach provides a scientific basis for standardizing the clinical application of traditional Chinese medicine injections and offers an operable paradigm for implementing differentiated drug use supervision in medical institutions.

OBJECTIVE To provide a reference for anticoagulation therapy, adverse drug reaction monitoring, and individualized medication adjustment in complex cases, such as those with thrombocytopenia following bioprosthetic heart valve replacement. METHODS Clinical pharmacists participated in the pharmaceutical care of a patient with thrombocytopenia following bioprosthetic heart valve replacement. For cardiac insufficiency, the pharmacists recommended maintaining oral bisoprolol, sacubitril/valsartan, spironolactone, furosemide, and potassium chloride, with levosimendan added to enhance myocardial contractility, while monitoring blood pressure, heart rate and serum potassium levels. For thrombocytopenia, based on literature- based risk assessment, the pharmacists advised administering recombinant human interleukin-11 (rhIL-11), platelet transfusion, and employing anticoagulation therapy with nadroparin calcium bridging to warfarin, with warfarin dosage adjusted according to the international normalized ratio (INR). For rapid ventricular rate atrial fibrillation, amiodarone and digoxin were recommended. For acute liver injury, suspected to be induced by amiodarone and rhIL-11, the pharmacists suggested discontinuing the relevant drugs and treating with ademetionine 1,4-butanedisulfonate combined with polyene phosphatidylcholine for liver protection treatment. The patient received anticoagulation medication education emphasizing strict INR monitoring and close observation for bleeding or thrombotic events. RESULTS The clinicians adopted these recommendations. Following the intervention, the patient’s liver function showed significant improvement, with alanine aminotransferase decreasing to 70 U/L and aspartate aminotransferase to 42 U/L. The ventricular rate stabilized at 70-100 beats per minute, cardiac function remained stable, the INR was maintained within the target range of 1.80-2.50, and the patient was ultimately discharged with improved condition. CONCLUSIONS Through balancing anticoagulation and bleeding risks, the clinical pharmacists applied pharmaceutical expertise to assist in developing personalized anticoagulation regimens, conducted adverse drug reaction monitoring and evaluation, and optimized medication strategies, thereby effectively ensuring patient safety and therapeutic efficacy.

Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

BackgroundAdverse childhood experiences (ACEs) are strong predictors of psychopathology across the lifespan, exerting extensive adverse effects on physical and mental health during early development. While ACEs increase the risk of childhood psychopathology, sleep quality and impair cognitive function, the early neurobiological mechanisms mediating ACE-induced cognitive impairment remain unclear. ObjectiveTo explore the association between ACEs exposure and the risk of psychopathology, sleep disorders, and cognitive function, and to examine the mediating role of the putamen volume in the relationship between ACEs and cognitive function from a neurodevelopment perspective. MethodsData were obtained from the Adolescent Brain Cognitive Development (ABCD) study, comprising 10 572 children aged 9 to 10. Participants were categorized into five groups based on the cumulative score of ACEs reported by their parents and the children themselves: no-exposure group (0 types of ACEs), the one-exposure group, the two-exposure group, the three-exposure group, and the high-risk exposure group (≥ 4 types of ACEs). Logistic regression analysis was employed to evaluate the association between ACEs and psychopathological symptoms [T score of the Child Behavior Checklist (CBCL) ≥ 65]. Multiple linear regression analysis was ultilized to analyze the correlations between ACEs and the scores of the Sleep Disturbance Scale for Children (SDSC), the NIH Toolbox Cognition Battery (NIHTB-CB), as well as the multiple structures in the cerebral cortex and subcortex. The Bootstrap method was applied to test the mediating effect of the putamen volume between ACEs and neurocognitive function. ResultsAfter adjusting for confounders, ACEs cumulative score was correlated with children's psychopathological symptoms in a dose-response manner. Compared with the no-exposed group, the high-risk exposure group had a 2.08-fold (OR=2.080, 95% CI: 1.401–3.088) increased risk of internalizing problems and a 3.13-fold (OR=3.132, 95% CI: 1.703–5.760) increased risk of externalizing problems, and the risk of conduct problems was 4.68 times that of the no-exposed group (OR=4.681, 95% CI: 2.528–8.669). ACEs cumulative score positively predicted the total score of SDSC (β=0.080, 95% CI: 0.059–0.102), with relatively stronger predictive effects on sleep-wake transition disorder (β=0.086, 95% CI: 0.063–0.109) and sleep onset and maintenance disorder (β=0.066, 95% CI: 0.043–0.089). In terms of neurocognition and brain structure, ACEs cumulative score negatively predicted the overall cognitive composite score (β=-0.025, 95% CI: -0.050–-0.001), the crystallized cognitive composite score (β=-0.035, 95% CI: -0.060–-0.010), the volume of the left putamen nucleus (β=-0.025, 95% CI: -0.046– 0.003), and the volume of the right putamen nucleus (β=-0.023, 95% CI: -0.044– 0.003). The total putamen volume played a partial mediating role between ACEs and the overall cognitive composite score, the effect value was -0.002 (95% CI: -0.004–-0.001), accounting for 7.49% of the total effect. ConclusionACEs exposure may increase the risk of psychopathological and sleep disturbances in children and may impair neurocognitive function. Reduced putamen volume may serve a potential neurobiological pathway underlying the impact of ACEs on childhood cognition.

ObjectiveTo investigate the clinical characteristics, diagnostic challenges, and treatment strategies in pediatric patients with ureteropelvic junction obstruction (UPJO) complicated with ipsilateral ureterovesical junction obstruction (UVJO). MethodsA retrospective analysis was conducted on clinical data of pediatric patients admitted to our hospital between January 2014 and December 2024 with a confirmed diagnosis of UPJO complicated with UVJO. The collected clinical parameters included gender, age at presentation, initial diagnosis, lesion laterality, imaging findings, surgical procedures, and follow-up outcomes. ResultsThe study cohort comprised 14 pediatric patients (male=10 and female=4) with a median age of 3.1 months at presentation. The initial diagnoses were UPJO in 9 cases and UVJO in 5 cases. Preoperatively, only 6 cased showed ureteral dilation on MRU. The definitive diagnosis was confirmed by intraoperative retrograde pyelography in 5 cases, postoperative antegrade pyelography via a nephrostomy tube in 7 patients, and combined application of the two modalities in 2 patients. For primary surgical intervention, 9 patients underwent pyelo-plasty, 2 underwent ureteral reimplantation, 2 received percutaneous nephrostomy, and 1 underwent ureteral orifice dilation. Intraoperative nephrostomy tube placement was performed in 10 patients. With a median follow-up duration of 5.5 years, 4 patients required revision surgery. Of these, only 1 patient , who had an initial diagnosis of UPJO, required staged management for persistent obstruction, whereas UPJ obstruction resolved after ureteroneocystostomy in the remaining 3 patients with an initial diagnosis of UVJO. Among the 10 patients who did not undergo revision surgery, 8 showed delayed distal urinary drainage on APG, yet remained asymptomatic with continuous improvement of hydronephrosis after nephrostomy tube clamping. ConclusionsPreoperative diagnosis of concurrent UPJO and ipsilateral UVJO in pediatric patients is clinically challenging. Further intraoperative evaluation is mandatory when antegrade or retrograde ureteral stent placement fails during surgery. For patients with an initial diagnosis of UPJO, pyeloplasty is the first-line treatment. Routine retrograde pyelography is not recommended, whereas nephrostomy tube with subsequent postoperative APG evaluation can prevent unnecessary ureteroneocystostomy. For patients with an initial diagnosis of UVJO accompanied by severe ureteral dilation, primary ureteroneocystostomy is feasible initial management strategy.

OBJECTIVE:
To explore the clinical significance of trisomy 7 signaled by non-invasive prenatal testing (NIPT).
METHODS:
Pregnant women with high risk for trisomy 7 by NIPT from January 2017 to December 2023 were selected as the study subjects, and the results of prenatal diagnosis and follow-up were analyzed. Literature related to pregnant women with a high risk for trisomy 7 by NIPT from January 2016 to July 2024 was retrieved from China Biomedical Literature Database, Wanfang Database, China National Knowledge Infrastructure and PubMed database. Relevant information such as the incidence of trisomy 7 by NIPT, positive predictive value (PPV), and pregnancy outcomes were collected. This study has been approved by the Medical Ethics Committee of Lianyungang Maternal and Child Health Care Hospital (Ethics No. JS2022010).
RESULTS:
A total of 51 women with a high risk for trisomy 7 by NIPT were identified. Thirty-two of them had chosen chromosomal microarray analysis (CMA) of amniotic fluid cells, and 1 case of mosaic trisomy 7 was detected, which had yielded a PPV of 3.13%. Four women had opted termination of pregnancy, 1 had miscarriage, 4 had pre-term and/or low weight birth, whilst the remaining 42 (82.4%) had full-term delivery. In total 19 literature were retrieved, which had involved 278 cases of trisomy 7 signaled by NIPT, among which 5 fetuses with mosaic trisomy 7 (3.14%) were confirmed. Among the 211 women with follow-up outcomes, 2 (0.95%) had intrauterine growth restriction, 3 (1.42%) had abnormal fetal structure detected by ultrasound, 2 (0.95%) had miscarriage, 9 (4.27%) underwent pregnancy termination, 28 (13.27%) had preterm and/or low weight birth, whilst 167 (79.14%) had normal delivery. In 18 cases, chromosomal analysis of placental tissue was carried out, and 17 were confirmed to have mosaicism trisomy 7.
CONCLUSION
The PPV for trisomy 7 signaled by NIPT is extremely low. Although most of such women had a full term delivery, adverse pregnancy outcomes may still occur in a minority of cases. Clinicians should provide adequate genetic counseling for such women and recommend appropriate prenatal diagnosis strategies and optimal perinatal management plans.
