OBJECTIVE: To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly. METHODS: Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et alin 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function. RESULTS: The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up. CONCLUSION The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

Objective To investigate the preventive effect of ipratropium bromide on sufentanil-induced cough during general anesthesia induction.Methods A total of 201 patients undergoing elective surgery under general anesthesia from June 2022 to September 2024 were selected and divided into the ipratropium bromide group(group P,n=100)and the normal saline group(group C,n=101).Thirty minutes before anesthesia in-duction,group P and group C received oral administration of ipratropium bromide inhalation aerosol(2 puffs,equivalent to 42 μg C20H30BrNO3·H2O)and 0.9%normal saline spray(2 puffs),respectively.Anesthesiolo-gists intravenously administered sufentanil(0.5 μg/kg)within 5 seconds,followed by propofol(2 mg/kg)and rocuronium(0.6 mg/kg)after 3 minutes.Endotracheal intubation was performed using a videolaryngo-scope after achieving satisfactory muscle relaxation.The occurrence of cough within 1 minute after sufentanil administration was recorded.Heart rate(HR),mean arterial pressure(MAP),and pulse oxygen saturation(SpO2)were measured at different time points.Results Within 1 min after sufentanil administration,the in-cidence of severe cough and total cough in group P was significantly lower than that in group C(P<0.05).There was no significant difference in HR,MAP,or SpO2 between the two groups at different times(P>0.05).No adverse reactions such as nausea,vomiting,or arrhythmia occurred in either group.Conclusion In-haling ipratropium bromide 30 min before anesthesia induction could effectively reduce sufentanil-induced cough and decrease the incidence of severe cough.

Objective To analyze the clinical and pathogenic characteristics,as well as influencing factors for the prognosis of patients with Candida bloodstream infection(CBSI).Methods Clinical data of 47 CBSI patients in a hospital from January 2015 to September 2024 were collected.Distribution of departments and infection strains,an-timicrobial resistance,and influencing factors for the poor prognosis of patients were analyzed.Results A total of 51 strains of Candida were detected from 47 CBSI patients,mainly from the intensive care unit(ICU;n=25,53.2％),department of intestinal fistula surgery(n=8,17.0％),and department of respiratory medicine(n=4,8.6％),et al.The main detected pathogens were Candida albicans(n=29,56.9％),Candida tropicalis(n=7,13.7％),Candida glabrata(n=6,11.8％),and Candida parapsilosis(n=6,11.8％).Resistance rate of Candida albi-cans to fluconazole was 11.5％(3/26).According to the prognosis results,patients were divided into a good prog-nosis group(n=26,55.3％)and a poor prognosis group(n=21,44.7％).Univariate analysis showed statistically significant differences between patients in the good prognosis group and the poor prognosis group in terms of abso-lute neutrophil count,ICU admission,mechanical ventilation,tracheal intubation,gastrointestinal hemorrhage/per-foration,and surgical treatment(lesion clearance,drainage or unblocking for obstruction)(all P＜0.05).Prelimi-nary multivariate logistic regression analysis showed that gastrointestinal hemorrhage/perforation was a potential risk factor for the poor prognosis in CBSI patients(OR=11.156,95％CI:1.434-86.809,P=0.021).Conclusion The detected CBSI strains are mainly Candida albicans,and gastrointestinal hemorrhage/perforation may be one of the potential risk factors affecting the prognosis of CBSI patients.These patients are generally in critical condition and should be detected and treated as early as possible to improve their prognosis.Due to the small amount of speci-mens,further research is still needed for confirmation.

OBJECTIVE To analyze the current status of hospital-acquired infections(HAI)in cancer patients in Henan Cancer Hospital,and explore the application of Case Mix Index(CMI)based on disease diagnosis-related groups(DRG)in the evaluation of HAI risks.METHOD Data on HAI of patients in cancer hospitals in Henan Province from Jun.2023 to Jun.2024 were statistically analyzed,including incidence rates,distribution of infec-tion sites and composition ratios of pathogens,high-risk departments were identified by CMI-adjusted 1 000-day incidence rates of HAI infections,and the current status of HAI in cancer patients were analyzed.RESULTS The incidence of HAI in cancer patients was 1.67％(4 315/259 087),and the incidence rate of HAI in 1 000 days was 2.46 per 1000.The sites of infection were mainly the respiratory tract,the abdominal cavity,the surgical sites and the bloodstream.A total of 2 381 strains of pathogens were cultured and isolated,including 1 570 strains of gram-negative bacteria,638 strains of gram-positive bacteria and 173 strain s of fungi,and the top five strains de-tected were Escherichia coli(24.49％),Klebsiella pneumoniae(15.41％),Pseudomonas aeruginosa(9.11％),Staphylococcus aureus(8.86％)and Staphylococcus epidermidis(4.66％).After CMI adjustment,the order of decreasing was dominated by surgical departments,while the order of increasing was dominated by non-surgical departments,and the top five departments with the highest adjusted incidence rates were Orthopedics and Soft Tissue department,Hematology department,Hepatobiliary Surgery department,General Surgery department and Urology department.CONCLUSIONS In the prevention and control of HAI in cancer patients,attention should be given to the gram-negative bacteria,and close monitoring of infections in the respiratory tract,abdominal cavity,and surgical sites is essential.This study uses the CMI to adjust the HAI incidence rate of cancer patients in order to identify high-risk departments that currently require focused management,it also analyzes the DRGs codes with a highest proportion of HAI in each department,with a particular focus on patients in these high-risk groups,and it aims to avoid and minimize the occurrence of HAI among cancer patients as much as possible through refined DRGs analysis and targeted prevention and control measures.

Objective:To explore the relationship between serum omentin-1 and 25-hydroxyvitamin D 3 [25(OH)D 3] levels and bone age index (BAI), pelvic ultrasound findings in girls with central precocious puberty (CPP). Methods:This was a cross-sectional observational study. A total of 150 girls with CPP admitted to the Shaanxi Provincial People′s Hospital from October 2021 to October 2023 were selected as the CPP group, and 63 normal girls who underwent physical examination at the child health clinic during the same period were selected as the control group. Serum Omentin-1 and 25(OH)D 3 levels were detected; anteroposterior X-ray and pelvic ultrasound examinations were performed to obtain BAI, ovarian volume, and uterine volume. Pearson correlation analysis was used to evaluate the correlations of Omentin-1 and 25(OH)D 3 with BAI, ovarian volume, and uterine volume. Multivariate logistic regression analysis was used to screen the influencing factors of CPP, and receiver operating characteristic (ROC) curve was drawn to analyze the value of Omentin-1 and 25(OH)D 3 in diagnosing CPP. Results:The serum levels of Omentin-1 and 25(OH)D 3 in the CPP group were lower than those in the control group (all P<0.05); BAI, uterine volume, and ovarian volume in the CPP group were larger than those in the control group, and the number of follicles with diameter ≥4 mm was more than that in the control group (all P<0.05). In girls with CPP, serum Omentin-1 and 25(OH)D 3 levels were negatively correlated with BAI, uterine volume, ovarian volume, and the number of follicles with diameter ≥4 mm (all P<0.05). Multivariate logistic regression analysis showed that maternal menarche age ≤12 years, high BMI, high BAI, and high estradiol were risk factors for CPP (all P<0.05), while high Omentin-1 and high 25(OH)D 3 were protective factors for CPP (all P<0.05). The areas under the curve (AUC) of Omentin-1 and 25(OH)D 3 for diagnosing CPP were 0.799 and 0.808 respectively; the AUC of combined diagnosis was 0.886, which was higher than that of single diagnosis (all P<0.05). Conclusions:Decreased serum Omentin-1 and 25(OH)D 3 levels in girls with CPP are associated with high BAI and increased ovarian and uterine volumes. The combination of Omentin-1 and 25(OH)D 3 has high value in the diagnosis of CPP.
