Objective To explore the clinical results of minimally invasive therapy for femoral intertrochanteric fractures with proximal femoral nail anti-rotation(PFNA) in 25 elderly patients.Methods A total of 25 patients with intertrochanteric fractures were treated by PFNA in our hospital from February 2007 to June 2008.The patients received close reduction and minimal invasive operation.Based upon the Tronzo-Evans classification,type Ⅰ fractures were diagnosed in 2 cases,type Ⅱ fractures in 2 cases,type Ⅲ in 16,and type Ⅳ in 5.Results The mean operation time in this series was 50.3 min(30-70 min),an the mean intraoperative blood loss was 100.2 ml(70-200 ml).All the 25 patients completed a follow-up of 3 to 12 months(average time 7.1 months),during which all the fractures healed in 10 to 14 weeks with a mean of 11 weeks,without occurrence of varus deformity,hardware loosening or hardware cutting.According to the Harris Hip Score,20 cases achieved excellent results,4 were good,and 1 was fair. Conclusions It is a reliable and ideal method to treat intertrochanteric fractures with PFNA in elderly patients,for the procedure is convenient and minimally invasive,resulting in firm fixation,less blood loss,short operation time,and high healing rate.

Abstract: Objective　To analyze the risk factors for HIV/AIDS mortality after receiving antiviral treatment in Tongchuan City, and to provide a scientific basis for implementing precision treatment in Tongchuan City. Methods　A retrospective cohort study was conducted to collect general demographic characteristics and survival-related information of HIV/AIDS individuals who received antiviral treatment in Tongchuan City from 2005 to 2023. Mortality table analysis was used to assess the cumulative survival rate, Cox regression model was used to analyze survival influencing factors, and a nomogram was constructed to predict the prognosis of antiviral treatment. Results A total of 410 HIV/AIDS patients underwent antiviral treatment, with the shortest observation period being 0 months and the longest 222 months, and the median survival time was 71 months (QR: 64-106); among the 362 cases followed up, there were 39 AIDS-related deaths. The cumulative survival rates after 1, 5, and 10 years of antiretroviral therapy were 96.2%, 91.3%, and 83.0%, respectively. Multivariate Cox analysis showed that patients with a higher level of education (college degree or above) (HR=0.349, 95%CI: 0.159-0.769) and without clinical symptoms (HR=0.357, 95%CI: 0.178-0.715) had a lower risk of death after antiretroviral treatment, whereas patients with a CD4 cell count <200 cells/μL group (HR=9.383, 95% CI: 2.879-30.578) had a higher risk of death. Based on the above three influencing factors, a nomogram model was constructed. Internal validation showed that the model's discriminative ability with a C-index of 0.859 (95% CI: 0.762-0.956), and the calibration curve indicated good consistency, demonstrating the model's good predictive ability. Conclusions　Tongchuan City should expand health education on AIDS prevention and control, strengthen HIV monitoring, carry out education on compliance with antiviral treatment among HIV/AIDS individuals, conduct timely CD4 cell count detection, and use the constructed nomogram model to assist in precise diagnosis and treatment in clinical practice.

Objective: To evaluate the efficacy of postoperative radiotherapy in the treatment of parotid gland carcinoma. Methods: Eighty-six postoperated patients with parotid gland carcinoma( 7 in stage Ⅰ, 28 in stage Ⅱ, 33 in stage Ⅲ and 18 in stage Ⅳ) were radiated by 60Co ?-ray or linear accelerator X-ray combined with electron beam. All patients were diagnosed by pathology and followed up for more than 5 years. Results: The five year survival rate and the local control rate were 73.3% and 87.2% respectively. Poor prognosis was observed in the cases with the neoplastic classification of undifferentiated carcinoma, sequamous cell carcinoma and malignant pleomorphic adenoma, but the better prognosis was obtained in the cases with acinic cell carcinoma and mucoepidermoid carcinoma. Poor prognosis was observed in the cases with stage Ⅲ and Ⅳ of clinical stage. Radiotherapy undertaken in 2 weeks after surgical operation gave higher 5- year survival ratio( 83.8%). The group given 51～60 Gy radiation showed 82.9% of five- year survival rate. Conclusion: The combination of surgery with radiation is effective in the treatment of parotid gland carcinoma.Radiation of 51～60 Gy 2 weeks after operation may result in better prognosis. Neoplastic type and clinical stage are important factors for prognosis.

Objective : To examine the association between dietary patterns during pregnancy and gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the establishment of healthy and balanced dietary patterns and reducing the prevalence of GDM. Methods: Pregnant women who underwent oral glucose tolerance tests in Hangzhou Obstetrics and Gynecological Hospital from 2020 to 2021 were enrolled, and their demographic information were collected using questionnaires. Pregnant women's diets during the past three months were collected using Food Frequency Questionnaires (FFQs), and dietary patterns were extracted using principal component analysis. In addition, the association between dietary patterns and risk of GDM was examined using a multivariable logistic regression model. Results: A total of 1 689 pregnant women were included, with a median age of 28.53 (interquartile range, 2.47) years and a median gestational age of 26.00 (interquartile range, 2.00) weeks. Five dietary patterns were identified according to pregnant women's types of diets, including meat-based diets, dessert-fruit-refined grain diets, plant-based diets, eggs-milk-nut diets and whole-grain diets, with a cumulative contribution rate of 58.76%. The prevalence of GDM was 24.57% (415 cases) among the study subjects. Multivariable logistic regression analysis showed that pregnant women with scores in the highest quartile (Q4) of the meat-based diets had an increased risk of GDM (OR=1.372, 95%CI: 1.043-2.055) relative to those with scores in the lowest quartile (Q1), and pregnant women with Q4 scores of the dessert-fruit-refined grain diets had an increased risk of GDM (OR=1.743, 95%CI: 1.397-2.432) relative to those with Q1 scores, while pregnant women with Q4 scores of the plant-based diets had a reduced risk of GDM (OR=0.382, 95%CI: 0.346-0.613) relative to those with Q1 scores. Conclusion A plant-based dietary pattern may reduce the risk of GDM, while meat-based and dessert-fruit-refined grain dietary patterns may increase the risk of GDM.

Objective To investigate the effects of protocadherin 20 (PCDH20) in the spinal cord in the development of bone cancer pain (BCP) in rats.Methods Thirty-six SPF female Sprague-Dawley rats,weighing 180-200 g,were randomly divided into 4 groups (n =9 each):sham operation group (group S),BCP group,lentivirus control group (group LC) and PCDH20 siRNA lentivirus group (group P).Control lentivirus and lentivirus containing PCDH20 siRNA 4 μl were injected into the ipsilateral spinal cord in groups LC and P,respectively.One week later,BCP was induced by injection of Walker 256 breast cancer cells into the upper segment of bone marrow of right tibia.The mechanical paw withdrawal threshold (MWT) was measured at 1 day before injection of lentivirus (T1),1 day before BCP (T2),and 7,14 and 21 days after BCP (T3-5).Three rats in each group were sacrificed after measurement of the MWT at 21 day after BCP and the tibia on the operated side was obtained for examination of invasion of the cancer cells with light microscope.The spinal cord was removed for determination of the expression of PCDH20 and postsynaptic density 95 (PSD95) protein (by Western blot) and mRNA (by RTPCR).Results In groups BCP,LC and P,the cancer cells grew out of the bone and destroyed the cortical bone seriously.Compared with group S,the MWT was significantly decreased at T3-5 in groups BCP,LC and P,the expression of PCDH20 and PSD95 protein and mRNA was up-regulated in groups BCP and LC,and the expression of PCDH20 was up-regulated in group P (P ＜ 0.05).Compared with BCP group,no significant change was found in the MWT and expression of PCDH20 and PSD95 protein and mRNA in group LC (P ＞ 0.05),and the MWT was significantly increased at T4,5 and the expression of PCDH20 and PSD95 protein and mRNA was down-regulated in group P (P ＜ 0.05).Conclusion PCDH20 is involved in the development of BCP through regulating the expression of PSD95 in the spinal cord and adjusting the function of excitatory synapse in rats.
