Objective:To compare the clinical outcomes between percutaneous Kirschner wire leverage plus plaster fixation and elastic intramedullary nailing in the treatment of radial neck fractures in children.Methods:A retrospective study was conducted to analyze the 60 children with radial neck fracture who had been treated by percutaneous Kirschner wire leverage plus plaster fixation at Department of Pediatric Orthopedics, Children's Hospital of Soochow University from January 2016 to July 2023 (set as an internal fixation-free group). They were 30 males and 30 females (34 left and 26 right sides) with an age of (7.7±3.0) years. At the same time, another cohort of 60 patients were chosen as an intramedullary nailing group who had been treated by percutaneous Kirschner wire leverage plus elastic intramedullary nailing and matched in age and gender with those in the internal fixation-free group. The preoperative fracture angulation, operative time, hospitalization time, fracture angulation on the first postoperative day, fracture angulation at 1 month postoperatively, rate of angulation loss after reduction, Mayo elbow performance score (MEPS) at the last follow-up and complications were compared between the 2 groups.Results:There was no significant difference between the 2 groups in their preoperative general data, showing comparability ( P<0.05). The 120 pediatric patients were followed up for (7.5±3.2) months. The operative time [(27.4±15.0) min] and hospitalization time [(3.4±1.9) d] in the internal fixation-free group were significantly shorter than those in the intramedullary nailing group [(45.4±13.5) min and (4.4±1.3) d] ( P<0.05). The preoperative fracture angulation (50.8°±1.9°), fracture angulation on the first postoperative day (11.3°±1.2°), fracture angulation at 1 month postoperatively (12.1°±1.3°), rate of angulation loss after reduction (2.9%±0.5%), and MEPS at the last follow-up [(90.4±2.0) points] in the internal fixation-free group showed no significant differences from those in the intramedullary nailing group [49.5°±1.7°, 11.1°±1.2°, 13.3°±1.5°, 3.9%±1.4%, and (90.2±2.3) points] ( P>0.05). None of the patients in the internal fixation-free group developed pin-tail irritation sign or premature epiphyseal closure after surgery, whereas 3 patients in the intramedullary nailing group developed pin-tail irritation sign and 2 ones premature epiphyseal closure after surgery, showing a significant difference in the complication rate between the 2 groups [0 (0/60) versus 8.3% (5/60)] ( P<0.05). Conclusions:Percutaneous Kirschner wire leverage plus plaster fixation and close elastic intramedullary nailing can both achieve satisfactory outcomes in the treatment of radial neck fractures in children. However, percutaneous Kirschner wire leverage plus plaster fixation needs shorter operative time and hospitalization time, leads to fewer complications, and requires no reoperation to remove internal fixation.

In 2009,the World Health Organization included snakebite on the list of neglected tropical diseases,acknowledging it as a common occupational hazard for farmers,plantation workers,and others,causing tens of thousands of deaths and chronic physical disabilities every year.This guideline aims to provide practical information to help clinical professionals evaluate and treat snakebite victims.These recommendations are based on clinical experience and clinical research evidence.This guideline focuses on the following topics:snake venom,clinical manifestations,auxiliary examination,diagnosis,treatments,and prevention.

Objective To investigate the effect of interaction between serum neutrophil gelatinase-associat-ed lipid carrier protein(NGAL)and complications after percutaneous coronary intervention(PCI)on poor prognosis in patients with ST-segment elevation myocardial infarction(STEMI),and to provide reference for improving prognosis.Methods From January 2017 to January 2020,a total of 400 STEMI patients admitted to this hospital were selected and divided into good prognosis group(n=378)and poor prognosis group(n=22)according to their 2-year prognosis.Logistic regression equations were used to analyze the prognostic fac-tors of STEMI patients,and multiplicative and additive effects were established to analyze the effect of the in-teraction between serum NGAL and post-PCI complications on poor prognosis.Results Gender,age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were associated with poor prognosis in STEMI patients(P＜0.05).Gender(female),age,heart rate,Gensini score,number of lesions ≥2,Killip grade,complications after PCI and NGAL level after PCI were all inde-pendent influencing factors of poor prognosis in STEMI patients(P＜0.05).There was interaction between serum NGAL after PCI and complications after PCI,both of which had an adverse effect on the prognosis of STEMI patients(P＜0.05).There was no multiplicative interaction between serum NGAL and complications after PCI(P＞0.05).When serum NGAL and complications after PCI were exposed at the same time,the risk of poor prognosis in STEMI patients was higher than the sum of the two exposures alone,and the interaction was 2.611 times the sum of the effects of the two exposures alone.Conclusion Serum NGAL and postopera-tive complications after PCI are independent factors influencing poor prognosis in STEMI patients.There is a additive interaction between the two factors,and exposure can increase the risk of poor prognosis.

Vascular cognitive impairment(VCI)includes a range of illnesses from mild cognitive impairment to dementia,attributable to cerebrovascular factors.Although appropriate animal models are needed to allow clinicopathological research and drug development,there are currently no animal models that can perfectly simulate the pathogenesis of VCI.At present,carotid artery and vertebral artery stenosis or occlusion are the main method for VCI modeling;however,increasing numbers of non-surgical method have recently emerged,providing new ideas and prospects for the study of this disease.In this paper,we consider the construction method,model mechanisms,and model characteristics of non-surgical animal models of VCI,to provide a reference to help researchers choose the most suitable animal model.

OBJECTIVE: To explore the clinical phenotype and genetic variant in a child with Verheij syndrome (VRJS). METHODS: A child who had presented at the Soochow University Affiliated Children's Hospital and Wujiang District Children's Hospital in July 2022 for "elevated scapula since early childhood" was selected as the study subject. Peripheral blood samples of the child and his parents were collected and subjected to whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child had manifested elevated scapulae, torticollis, neck asymmetry, facial dysmorphism, dispersed café-au-lait spots, limited mobility of upper limbs and shoulder joints, and intellectual disability. Sequencing revealed that he has harbored a de novo heterozygous c.405dupT (p.Ile136Tyrfs*4) variant of the PUF60 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), this variant was classified as pathogenic (PVS1+PS2_moderate+PM2_supporting). Combined his clinical features and result of genetic testing, the child was diagnosed with VRJS due to variant of the PUF60 gene. CONCLUSION The clinical manifestations of VRJS include facial dysmorphism, intellectual disability, elevated scapulae, vertebral fusion, other skeletal malformations, without significant abnormalities of the heart, kidney, and eyes, which need to be distinguished from Klippel-Feil syndrome. Above finding has expended the mutation spectrum of the PUF60 gene and provided a reference for delineation of the genotype-phenotype correlation of the VRJS.

Acute kidney injury and acute lung injury/acute respiratory distress syndrome are common in the pediatric intensive care unit.Lung-kidney interaction in critically ill patients is closely related to anoxia, fluid management, and inflammatory response in acute kidney injury and acute lung injury/acute respiratory distress syndrome patients.Strengthening the understanding of lung-kidney interaction can help clinicians to systematically manage critically ill patients.

Objective:To investigate the risk factors and their warning value for the occurrence of sepsis in patients with severe multiple trauma.Methods:A retrospective cohort study was conducted to analyze the clinical data of 92 patients with severe multiple trauma admitted to Yuyao People′s Hospital from July 2019 to October 2021. There were 71 males and 21 females, with the age range of 36-55 years [(45.5±13.6)years]. The injury severity score (ISS) was 20-29 points [(25.3±6.4)points]. The patients were divided into sepsis group ( n=32) and non-sepsis group ( n=60) according to whether sepsis occurred during hospitalization. Data were recorded for the two groups, including gender, age, basic diseases, cause of injury, number of injury sites, ISS, post-injury complications, and levels of aryl hydrocarbon receptor (AHR), C-reactive protein (CRP) and procalcitonin (PCT) at 1, 3 and 5 days after injury. The above data were analyzed to identify their correlation with the occurrence of sepsis in patients with severe multiple trauma by univariate analysis. The independent risk factors for sepsis in patients with severe multiple trauma were determined by multivariate Logistic regression analysis. The warning value of the single or combined risk factors for the occurrence of sepsis in patients with severe multiple trauma was evaluated by the receiver operating characteristic (ROC) curve and area under the curve (AUC). Results:By univariate analysis, it was demonstrated that the occurrence of sepsis was correlated with ISS, level of AHR at day 1 after injury, level of CRP at day 3 after injury and level of PCT at day 3 after injury ( P<0.05 or 0.01), but not with age, sex, basic diseases, level of AHR at 3, 5 days after injury, level of PCT at 1, 5 days after injury and level of CRP at 1, 5 days after injury (all P>0.05). By multivariate Logistic regression analysis, higher ISS ( OR=1.12, 95% CI 1.01, 1.24, P<0.05), level of AHR at day 1 after injury ( OR=1.30, 95% CI 1.10, 1.52, P<0.01) and level of PCT at day 3 after injury ( OR=1.81, 95% CI 1.08, 3.03, P<0.05) were found to be strongly correlated with the occurrence of sepsis. ROC curve analysis showed that higher ISS (AUC=0.69, 95% CI 0.57, 0.76) and level of AHR at day 1 after injury (AUC=0.79, 95% CI 0.68, 0.90) had warning value for the occurrence of sepsis, and the warning efficiency of combined panel was much better (AUC=0.86, 95% CI 0.77, 0.95). Conclusions:Higher ISS, level of AHR at day 1 after injury and level of PCT at day 3 after injury are independent risk factors for the occurrence of sepsis in patients with severe multiple trauma. ISS, AHR and combination of both exhibit good warning value for the occurrence of sepsis in patients with severe multiple trauma.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

OBJECTIVE To systematically evaluate the efficacy and safety of selective COX -2 inhibitors for preemptive analgesia in patients undergoing total hip/knee arthroplasty （THA/TKA），and to provide evidence -based reference for clinical drug use. METHODS Retrieved from CNKI ，VIP，CBM，Wanfang database ，PubMed，Embase，Scopus，Web of Science and Cochrane library ，randomized controlled trials about selective COX -2 inhibitors for preemptive analgesia combined with post - operative analgesia of THA/TKA （trial group ）versus post -operative analgesia （control group ）were collected during the inception to February 15，2022. After screening the literature and extracting the data ，the RCT bias risk assessment tool recommended by the Cochrane System Evaluator ’s Manual 5.1.0 was used to evaluate the quality of the included literature . Meta-analysis was performed by using RevMan 5.3 software. RESULTS Six RCTs involving 916 patients were included . The visual analog （VAS）scale scores of pain at rest [MD＝－0.20，95%CI（－0.30，－0.10），P＜0.000 1]，VAS scores of pain at movement [MD＝－0.20，95%CI （－0.27，－0.13），P＜0.000 01]，total consumption of patient controlled analgesia （PCA） [MD＝－5.89，95%CI（－8.98， －2.80），P＝0.000 2]，and the incidence of postoperative nausea and vomiting [RR＝0.79，95%CI（0.65，0.95），P＝0.01] in trial group were significantly lower than control group . CONCLUSIONS Compared with postoperative administration alone ，preemptive plus postoperative analgesia with selective COX -2 inhibitor can significantly alleviate the early postoperative pain ，reduce the total consumption of PCA and the incidence of postoperative nausea and vomiting in THA/TKA patients .

Objective:To evaluate the effect of short-term very low-calorie restriction(VLCR) on glycemic control in overweight/obese patients with type 2 diabetes, and to explore mechanisms through identifying markers of gut microbiota.Methods:This trial was conducted in 14 adult overweight/obese patients with type 2 diabetes. They received VLCR for 9 days in the hospital(calorie intake 300-600 kcal/d). Before and after VLCR, body weight(BW), waist circumference(WC), blood pressure(BP), and heart rate(HR) were measured, and body mass index(BMI) was calculated according to their height and weight. Fasting blood glucose(FBG), 2 h postprandial blood glucose(2hPBG), fasting insulin(FINS), triglycerides(TG), total cholesterol(TC), high-density lipoprotein-cholesterol(HDL-C), and low-density lipoprotein-cholesterol(LDL-C) were determined, and yielded the homeostasis model assessment for insulin resistance(HOMA-IR). Additional lab tests such as liver and kidney function and electrolytes were performed. The estimated glomerular filtration rate(eGFR) was calculated to evaluate renal function. All data were analyzed using the SPSS Sample Power software. Feces samples were collected before and after VLCR. Fecal samples were tested for microbial diversity using 16S rDNA technology. Professional software was used to analyze the differences of gut microbiota in feces before and after VLCR.Results:After 9 days of VLCR, BW, BMI, WC, BP, HR, FBG, 2hPBG, FINS, HOMA-IR, alkaline phosphatase, TG, and blood urea nitrogen of 14 overweight/obese patients with type 2 diabetes were significantly reduced( P<0.05). No effect was seen on serum alanine aminotransferase, aspartate amino transferase, gamma glutamyl transferase, TC, HDL-C, LDL-C, creatinine, eGFR, uric acid, albumin, calcium, and phosphorus( P>0.05). The gut microbiota diversity did not differ before and after VLCR. The abundance of Bacteroidetes increased significantly, and the Firmicutes/Bacteroidetes ratio decreased from 11.79 to 4.20. Between groups analysis showed the abundance of Parabacteroides distasonis increased significantly after VLCR. Conclusion:VLCR can improve body weight and glucose and lipid metabolism in overweight/obese patients with type 2 diabetes, with no serious adverse events. Parabacteroides distasonis may be a marker of VLCR.
