OBJECTIVE To investigate the relationship between nurse-to-patient ratios and hospital-acquired infec-tions(HAIs)in the intensive care units,and to assess the impact of both average and maximum nurse-to-patient ratios on the risk of HAIs.METHODS Data were obtained from the hospital information system(including Hospi-tal Information System,nursing sensitive quality indicator monitoring system and hospital infection management system).Inpatients aged 18 years and older in ten intensive care units from 1 Jan.2022 to 31 Dec.2023 were in-cluded;data on the nurse-to-patient ratios during day shifts,night shifts and the overall period and HAIs cases were collected.Univariate test was conducted to compare differences between the infection group and the non-infection group.Logistic regression models were utilized to evaluate the association between various nurse-to-patient ratio indicators and the risk of HAIs while controlling the covariates.RESULTS A total of 2 742 patients were included,with an HAIs incidence rate of 18.23％.The average patient-to-nurse ratio was significantly low-er in the infection group than in the non-infection group(2.76±0.82 vs.3.27±1.16,P＜0.001),whereas the maximum nurse-to-patient ratios for the overall period,day and night shifts were 3.57±1.09(infected)vs.3.91±1.31(uninfected),3.30±1.12 vs.3.48±1.16,and 4.62±1.85 vs.5.10±2.08,respectively(all P＜0.001).Regression analysis showed that no significant association between the average nurse-to-patient ratios for the overall period,day and night shifts and the risk of HAIs;whereas the odds ratios(ORs)for the maximum patient-to-nurse ratio greater than 4 were 2.122(1.355-3.324)for the overall period,2.061(1.333-3.186)for the day shift and 1.495(1.055-2.118)for the night shifts(all nurse-to-patient ratios≤3 in the reference group).CONCLUSIONS The maximum nurse-to-patient ratios are important risk factors for HAIs in the intensive care u-nits,whereas the average nurse-to-patient ratios are not significantly associated with HAIs.It is suggested that in-sufficient nursing resources during peak hours may increase the risk of infection,and optimizing the allocation of nursing care during peak hours will help to reduce the incidence of HAIs.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective To investigate the clinical value of gallbladder function in predicting postoperative complications after endoscopic treatment of calculus of common bile duct.Methods 118 patients with complete gallbladder who underwent endoscopic clearance for calculus of common bile duct were selected from January 2018 to December 2022.After the liver function recovered to normal,the patients underwent lipid meal ultrasound examination to evaluate fasting volume,residual volume,and gallbladder ejection fraction(GBEF).The relationship between clinical features,gallbladder function and recurrent biliary complications was analyzed in patients with calculus of common bile duct.Results Among the 118 patients with calculus of common bile duct,86 had concomitant cholecystolithiasis,while 32 did not.During the follow-up period,23 patients developed biliary complications.Among the 86 patients with concomitant cholecystolithiasis,15 had spontaneous clearance of cholecystolithiasis,14 underwent cholecystectomy due to acute cholecystitis or recurrent abdominal pain,and 6 died of non-biliary causes.The GBEF of the patients with cholecystolithiasis was significantly lower.Cholecystolithiasis,alcohol consumption,and more than one endoscopic treatment were the risk factors for recurrent biliary complications after endoscopic treatment of calculus of common bile duct.Conclusion Patients with calculus of common bile duct combined with cholecystolithiasis have poor GBEF.Cholecystolithiasis,alcohol consumption,and more than one endoscopic treatment are the risk factors for recurrent biliary complications after endoscopic treatment of calculus of common bile duct.Since cholecystolithiasis may spontaneously resolve,conservative monitoring of the gallbladder after endoscopic treatment for calculus of common bile duct is appropriate,but regular follow-up is necessary for high-risk patients.

The paper reported a patient under maintained hemodialysis for 11 years, with a large mass appeared in the right thigh after local injury. The mass was clinically considered as tumoral calcinosis combined with clinical, imaging and pathological findings. Several treatments such as enhancing dialysis adequacy, low calcium dialysate, calcimimetic agent, non-calcium- phosphorus binding agents, parathyroidectomy and intravenous infusion of sodium thiosulfate could not vanish the mass. Finally, the lump was surgically removed. The treatment of tumoral calcinosis in the hemodialysis patient can provide a instruction for similar situations in clinical practice.

Objective: To analyze the clinical application of the open supraclavicular approach in thyroidectomy. Methods: The clinical practicability of open supraclavicular thyroidectomy was explored by comparing the traditional anterior low arc incision thyroidectomy procedure with open supraclavicular thyroidectomy in terms of patients'aesthetic satisfaction, effectiveness of the operation, operation time, and so on. Result: Twenty-two cases of open supraclavicular thyroidectomy (group B) had better aesthetic satisfaction than 29 cases of traditional incision thyroidectomy (group A)(P<0.05), and had the same operative effect with traditional incision. Open supraclavicular thyroidectomy is associated with good aesthetic satisfaction, and has the same effect as the traditional incision does. Conclusions: Open supraclavicular thyroidectomy has good clinical value for benign thyroid tumors and some malignant tumors that require unilateral lobectomy, and even for tumors larger than the incision diameter. It has good aesthetic value while ensuring the curative effect of surgery.

Objective To evaluate the predicting value of circulating miRNAs for sepsis secondary to pneumonia in elderly patients.Methods From April 2016 to January 2017,44 cases with sepsis secondary to pneumonia,52 elderly patients with pneumonia and 21 healthy older adults as control were involved in this study.The expression levels of MiRNA-150 5p,miRNA-25-3p,miRNA-122 5p and miRNA-223-3p in plasma were evaluated by fluorescence quantitative PCR.The demographic characteristics,sequential organ failure assessment (SOFA)scores,prognosis and days stayed in ICU were recorded.The area under the receiver operating charaeteristic(ROC)curve was used to calculated the specificity and sensitivity of miRNA in identifying sepsis-associated pneumonia.Results There were significantly differences among levels of circulating miRNA-223-3p in pneumonia,sepsis and healthy control groups(F =36.441,P =0.000),△CT values were 2.39 ± 1.36,1.44± 1.43,and 4.58 ± 0.91,respectively.The relative expression levels of miRNA-223-3p in the three groups were significantly different (P =0.000),which were 0.189 (0.107,0.367),0.361 (0.221,0.735),and 0.044 (0.022,0.061),respectively.The AUC of miRNA-223-3p for predicting sepsis from pneumonia was 0.964(95 ％CI =0.925 1.000).At a cutoff value of 2.759,miRNA-223-3p yielded a sensitivity of 82.9％ and a specificity of 100.0％.Conclusions MiRNA-223-3p expression is up-regulated in patients with sepsis secondary to pneumonia compared to that of patients with pneumonia,and it could be used to predict sepsis associated pneumonia.
