Objective To investigate the diagnostic value of neutrophils CD64(nCD64)index,C reactive protein(CRP),interleukin-6(IL-6)and procalcitonin(PCT)in viral and bacterial upper respiratory tract infections.Methods Patients with upper respiratory tract infection treated in Hangzhou Xixi Hospital Affiliated to Zhejiang Chinese Medical University from January 2023 to January 2024 were selected as study objects.According to the results of etiological examination,they were divided into bacterial infection group(46 cases)and viral infection group(58 cases).The levels of nCD64 index,CRP,IL-6 and PCT before medication were compared between two groups.Receiver operating characteristic(ROC)curve was used to evaluate the value of infection markers in the differential diagnosis of bacterial and viral upper respiratory tract infections.Results The levels of CRP,nCD64 index,IL-6 and PCT in bacterial infection group were significantly higher than those in viral infection group(P＜0.01).ROC curve results showed that the area under the curve(AUC)of nCD64 index,CRP,PCT and IL-6 to distinguish the two types of infection were 0.818,0.776,0.692 and 0.654,respectively,and the combined AUC of four indexes was 0.870.Conclusion nCD64 index,CRP,IL-6 and PCT are closely related to the pathogen types of patients with upper respiratory tract infection,and the combined detection of all indicators can improve the diagnostic efficiency of upper respiratory tract infection types.

Objective To explore the application value of heparin binding protein(HBP),neutrophil to lymphocyte ratio(NLR),lymphocyte to monocyte ratio(LMR),and platelet to lymphocyte ratio(PLR)in the evaluation of immune function reconstruction in human immunodeficiency virus(HIV)infected individuals/acquired immunodeficiency syndrome(AIDS)patients.Methods Collect 138 HIV/AIDS patients from the Outpatient Department of Hangzhou Xixi Hospital Affiliated to Zhejiang Chinese Medical University from January 1,to June 30,2023.According to CD4+T lymphocyte counts after antiretroviral treatment,categorize patients into groups with good immune function reconstruction(n=108)and poor immune function reconstruction(n=30).Compare the levels of HBP,NLR,LMR,and PLR between two groups,receiver operating characteristic(ROC)curve was used to evaluate the application value of HBP,NLR,LMR,and PLR in the reconstruction of patient immune function.Results The NLR and PLR of group with good immune function reconstruction was significantly higher than that of group with poor immune function reconstruction(P＜0.05).The LMR of group with good immune function reconstruction were significantly lower than those of group with poor immune function reconstruction(P＜0.05).The HBP between two groups was no significant differences(P＞0.05).LMR had the best efficacy in evaluating whether immune function reconstruction was good in HIV/AIDS patients area under the curve(AUC)=0.803,PLR was the second(AUC)=0.796,NLR was poor(AUC)=0.728.Conclusion NLR,LMR,and PLR are closely related to the immune function of HIV/AIDS patients and can be used as detection indicators to evaluate whether the immune function reconstruction of HIV/AIDS patients is good.

Objective To explore the mechanism underlying ITGB1-induced drug resistance in gastric cancer based on the circRNA-miRNA-ITGB1 regulatory network.Methods Tumor tissue samples were collected from 21 patients with gastric cancer.The ITGB1 gene expression levels were determined using real-time fluorescent quantitative polymerase chain reaction,and circRNA sequencing was performed to compare the differences in circRNAs between patients with low and high ITGB1 expression.BGC-823 cells were trans-fected with si-circ_0027189,si-miR-455,or si-NC and divided into the si-circ_0027189,si-miR-455,or si-NC groups,respectively.The circ_0027189,miR-455,and ITGB1 expression levels in each group and the sensitivity to oxaliplatin were measured.Results The circRNA regulatory network showed that circ_0027189 regulated ITGB1 expression through miR-455.Compared to the si-NC group,the si-circ_0027189 group exhibited decreased expression levels of circ_0027189 and ITGB1,increased expression levels of miR-455,and reduced sensitivity to oxaliplatin.In contrast,the si-miR-455 group showed decreased expression levels of miR-455,increased expression levels of ITGB1,and enhanced sensitivity to oxaliplatin compared to the si-NC group.Conclusion circ_0027189 can increase ITGB1 expression levels by targeting miR-455 expression,ultimately increasing drug resistance in gastric cancer cells.

Objective:To investigate the association between shift work and the risk of lower extremity osteoarthritis.Methods:The study population came from the Dongfeng-Tongji cohort established in 2008. In September 2008, the Dongfeng Motor Company in Hubei Province was to recruit all retired workers who voluntarily participated in the survey as the research objects. During the follow-up conducted from April to October 2013, a total of 14 438 retired workers, i.e. all of the participants who underwent physical examination were investigated about demographic characteristics, lifestyles, occupation history, and lower extremity joint-related medical history, and additionally completed lower extremity joint examinations. After excluding individuals with missing data regarding lower extremity osteoarthritis, with the history of lower extremity joint trauma, or with history of rheumatoid arthritis (N=532), data from 13 906 participants was analyzed in the study. Multivariate logistic regression models were used to estimate the association between shift work and lower extremity osteoarthritis. After stratified by the duration of shift work, multivariate logistic regression models were used to analyze the relationship between the duration after leaving from shift work and lower extremity osteoarthritis.Results:Finally, a total of 13 906 retired employees included 7 560 (54.4%) females with a mean age of 64.74 (standard deviation 8.23) years old. 5 537 (39.8%) workers had ever engaged in shift work, including 2 004 (14.4%) workers with 1-9 years of shift work and 3 533 (25.4%) workers with ≥ 10 years of shift work. The prevalence of lower extremity osteoarthritis was 7.0%, while the prevalence of knee osteoarthritis and hip osteoarthritis were 6.7% and 0.7%, respectively. Compared with daytime workers, shift workers showed a 22% increase in the risk of lower extremity osteoarthritis ( OR=1.22, 95 %CI:1.06-1.40). Each 5-year increase in the duration of shift work was associated with a 4% increase in the risk of lower extremity osteoarthritis ( OR=1.04, 95 %CI:1.01-1.08). With the extension of the duration after leaving from shift work, the risk of lower extremity osteoarthritis decreased. Similar relationships were found between shift work and the risk of knee osteoarthritis, as well as hip osteoarthritis. Conclusion:Shift work was associated with the increased risk of lower extremity osteoarthritis.

Objective To introduce two modified surgical procedures for the treatment of chronic subdural hematoma (CSDH) and explore their clinical efficacies. Methods The clinical data of 100 CSDH patients, admitted to our hospital from March 2012 to February 2017, were retrospectively analyzed. Hematoma evacuation plus T-tube drainage was performed in 43 patients and minimally invasive microsurgery in 57 patients. Follow up of treatment efficacies was performed. Results During surgery, hematoma drainage of 5 patients (5%) was poor and the removal of hematoma was expanded. The clinical symptoms and signs of all of the patients improved after operation. Postoperative 24 h CT indicated that the ipsilateral subdural subdural effusion was found in 36 patients (36%), a small amount of ipsilateral subdural air was found in 13 patients (13% ), and a small amount of residual hematoma was found in 6 patients (6%). Follow up for 3-6 months indicated that subdural subdural effusion, subdural air and residual hematoma were absorbed completely; no hematoma recurrence, intracranial infection, scalp incision infection or death were noted; contralateral chronic subdural hematoma was found in one patient (1%), and hematoma was absorbed after conservative treatment. Clinical symptoms and signs of all patients were significantly improved and disappeared. Conclusion The minimally invasive double-hole hemodilution assisted with T-tube wall-draining or minimally invasive hematoma evacuation can effectively treat CSDH, and the postoperative complications are few;the above two surgical methods are worthy of clinical use, especially application and popularization of primary hospital.
