BACKGROUND:With the development of the aging trend of society,the incidence of femoral neck fractures is increasing.Currently,the preferred surgical treatment is cannulated screw internal fixation.However,post-surgical femoral neck shortening occurs in some cases,resulting in impaired hip functionality.OBJECTIVE:To investigate the incidence of femoral neck shortening following the use of half-threaded cannulated screws for internal fixation in patients with femoral neck fractures,to analyze the effect on hip function,and to identify factors contributing to neck shortening.METHODS:A retrospective analysis was conducted on the medical records of 102 patients treated with half-threaded cannulated screws in an inverted triangle setup for femoral neck fractures at Affiliated Hai'an Hospital of Nantong University from January 2016 to January 2021.This group included 36 males and 66 females at the mean age of(57.2±7.7)years,with 34 cases of Garden type Ⅰ and Ⅱ fractures and 68 of Garden type Ⅲ and Ⅳ fractures.The mean bone mineral density value T was-2.8 SD.The Harris score was used to evaluate the hip function.During the follow-up period,the occurrence of femoral neck shortening was determined using X-ray imagery,and the factors influencing this shortening were examined using both univariate and multivariate regression analyses.RESULTS AND CONCLUSION:(1)Among the 102 patients with femoral neck fractures,30 patients developed femoral neck shortening,accounting for 29.4％.72 patients had no femoral neck shortening(70.6％).(2)The Harris score for patients experiencing neck shortening was significantly lower than that for patients without shortening(P＜0.05).(3)The study identified several factors associated with femoral neck shortening following the internal fixation of femoral neck fractures included age,gender,bone mineral density value T,preoperative Garden classification,and quality of reduction.These factors not only affect the shortening of the femoral neck after surgery,but are also directly related to the functional performance of the patient's hip joint.(4)Femoral neck shortening after surgery for femoral neck fracture is associated with various clinical parameters,especially the patient's age,gender,bone mineral density,preoperative classification,and accuracy of reduction during surgery.

Objective To investigate the effect and mechanism of lentivirus-mediated overexpression of suppressors of cytokine sig-naling 3(SOCS3)on the heart of rats with experimental autoimmune myocarditis(EAM).Methods Thirty Lewis rats were randomly di-vided into a control group,EAM group and EAM+SOCS3 group.The EAM rat model was established by subcutaneous injection of cardiac myosin.On day 0 of the experiment,the EAM+SOCS3 group was injected with lentivirus overexpressing SOCS3 via the tail vein,and the EAM group was injected with an equal amount of empty vector lentivirus.On day 21 of the experiment,all rats underwent echocardio-graphy to evaluate cardiac function and were then euthanized.Hematoxylin-eosin(HE)staining was used to observe the pathological changes of myocardial tissue.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of serum cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial interleukin-6,interleukin-1 β and tumor necrosis fac-tor-α.Immunohistochemistry,real-time quantitative PCR(RT-qPCR)and Western blot(WB)were used to detect the expressions of SOCS3,Janus kinase 2(JAK2),signal transducer and activator of transcription 3(STAT3),monocyte chemoattractant protein-1(MCP-1),and transforming growth factor-β(TGF-β)in myocardial tissue.Results The myocardial pathological score,serum lev-els of cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial levels of interleukin-6,inter-leukin-1β,and tumor necrosis factor-α in the EAM group were significantly higher than those in the control group(P＜0.05).The cardiac function of the EAM group was significantly lower than that of the control group(P＜0.05).The mRNA and protein expressions of myocardial JAK2,STAT3,MCP-1 and TGF-β in the EAM group were significantly higher than those in the control group(P＜0.05).These indexes in the EAM+SOCS3 group were significantly restored compared with those in the EAM group(P＜0.05).The mRNA and protein expressions of SOCS3 in the myocardial tissue of the EAM+SOCS3 group were significantly higher than those in the EAM group(P＜0.05).Conclusion Overexpression of SOCS3 may ameliorates the inflammatory response of the myocardium in EAM rats and im-prove cardiac function by inhibiting the JAK2/STAT3 signaling pathway and downregulating the expressions of MCP-1 and TGF-β.

The university also constructs a participatory teaching method based on online-offline platforms, pre-class/post-class engagement, and on-campus/off-campus collaboration, as well as a teaching assessment system with multiple subjects, multiple dimensions, dynamic evolution, and virtue orientation. The university has also built a diversified collaborative educational practice platform among universities, hospitals, and communities, thereby forming a comprehensive medical humanities teaching model with the teaching of humanistic knowledge, the cultivation of humanistic spirit, and the training of good behaviors.

This article retrospectively analyzed the involvement of clinical pharmacists in the treatment process and implementation of pharmacological supervision in a patient with septic arthritis secondary to tophi ulceration.The patient was admitted to the hospital and the emergency debridement and tophi removal were performed.Piperacillin-tazobactam,imipenem cilastatin,levofloxacin,linezolid,and vancomycin were given successively,and multiple debridement and drainage were performed,but the patient remained febrile and had recurrent infection indicators.According to the relevant guidelines and evidence-based evidence,combined with the patient's infection indicators,pathogen results and creatinine clearance rate,the clinical pharmacists recommended stopping vancomycin and changing to cefazolin,and the clinicians adopted it.After that,the patient's inflammatory indicators gradually decreased,and the body temperature stabilized.After 28 days of piperacillin-tazobactam administration,the patient developed a reduction in white blood cell count(2.34×109·L-1)and potassium(2.98 mmol·L-1).The pharmacist recommended prompt discontinuation of the drug,and the patient's white blood cell count and potassium gradually recovered.Eventually,after anti-infective treatment and surgical intervention,the patient was discharged with closure of the infected foci,conversion of multiple blood cultures to negative,and stabilisation of body temperature and renal function.This case reflects the role of clinical pharmacists in the management of drug treatment of critically ill patients,and may provide practical experience and reference for clinical treatment of such cases.
