Objective To investigate the relationship of uteroglobin gene polymorphism to the sus-ceptibility to, clinical type and pathological type of Henoch-Schsnlein purpura (HSP) and Henoch-Schonlein purpura nephritis (HSPN). Methods Totally, 118 patients with clinically diagnosed HSP, including 80 cases of HSPN and 38 cases without renal involvement were recruited in this study together with 100 normal human healthy controls. Genomic DNA was isolated from peripheral blood leucocytes of all subjects. The uteroglobin G38A polymorphism was determined by PCR-restriction fragment length polymorphism (RFLP). Results The frequencies of genotypes 38GG, 38GA and 38AA in normal human controls did not differ from those in patients with HSP, patients with HSP but without nephritis, patients with HSPN, patients with HSP and joint involvement, patients with HSP and gastrointestinal involvement (all P > 0.05). Also, no sig-nificant difference was observed between patients with HSPN and patients with HSP but without nephritis (P > 0.05). Furthermore, the frequency of genotypes 38GG, 38GA and 38AA had no significant correlation to the clinical phenotype of HSP, the occurrence of gross hematuria and nephrotie syndrome or the degree of renal damage (all P > 0.05). A significant increase was observed in the frequency of genotype 38AA in patients with HSP with elevated serum IgE compared with those with normal serum lgE (58.82% vs 8.43%, χ2 = 21.946, P < 0.05, OR = 15.51, 95% CI range: 4.93% - 48.84%), whereas the frequency of genotype 38GG was significantly increased in patients with HSPN and hypertension than in those with HSPN but without hypertension (75.68% vs 18.60%, χ2 = 26.172, P < 0.05, OR = 13.61, 95% CI range: 5.01% -37.01%). Conclusions The uteroglobin G38A polymorphism seems unrelated to the susceptibility to and degree of renal damage in patients with HSP and HSPN. The genotype 38AA may be associated with elevated level of serum IgE In patients with HSP, while genotype 38GG is associated with a high incidence of hyper-tension in patients with HSPN.

Objective To investigate the clinical significance of leukocyte count and neutrophil count change on delayed traumatic intracranial hemorrhage(DTIH).Method Collected the peripheral venous blood of l 16 eases of DTIH and 123 cases of non-DTIH between June 2005 and Deeember 2007.Compared the leukocyte count and neutrophil count in all cases by different groups.Results The leukocyte count and neutrophil count of the DTIH patients whose first CT scan were negative[(13.35±6.72)×109/Land(12.78±6.43)×109/L,respectively]were significantly higher than those of head injury whose CT scan werenegative allthetime[(9.72±3.09)×109/Land(7.64±2.93)×109/L,respectively].The difference was significant (P＜0.01).There were no statistical significance of the leukocyte count and neutrophil count between DTIH patients and non-DTIH patients whose first CT scan were positive(P＞0.05).Conclusions As an independent guideline,the leukocyte count and neutrophil count may help the forepart diagnosis of DTIH patients whose first CT scan were negative.

Objective To design a new integrated portable biliary internal-external drainage catheter carrying125 I seeds used for the treatment of malignant biliary obstruction lesions so as to achieve the dual curative effects of biliary drainage and brachytherapy. Methods A total of 15 patients with malignant obstructive jaundice, who were admitted to the First Affiliated Hospital of Zhengzhou University, China, during the period from September 2016 to January 2018, were enrolled in this study. Biliary stent implantation was performed in all patients, which was followed by insertion of a new integrated portable biliary internal-external drainage catheter carrying125 I seeds. The technical success rate, clinical success rate, complications, stent patency time and patient survival rate were evaluated. Results The placement of the drainage tube was simple and smooth, and the technical procedure was successful in all patients. One month after treatment, the bilirubin level was decreased significantly when compared with preoperative one (P<0.01), while the blood indexes and immunological indicators showed no obvious changes (P>0.05) . After treatment, 2 patients (13.3％) developed cholangitis and 2 patients (13.3％) had small amount of biliary bleeding, which returned to normal after symptomatic treatment. No severe complications such as perforation of bile duct, massive bleeding, radiation enteritis and radioactive source leakage, etc., occurred. The patients were followed up for 55-402 days, 6 patients (40.0％) developed biliary re-obstruction. The median patency time of stent was 255 days, and 6-month stent patency rate was 64.5％. Five patients died and 10 patients survived, the 9-month survival rate was 64.3％, the median survival time was 368 days. Conclusion By using the new integrated portable biliary internal-external drainage catheter carrying125 I seeds, the effects of bile drainage and brachytherapy can be simultaneously achieved. Preliminary clinical practice indicates that this new drainage catheter is feasible, safe and effective, although its long-term efficacy needs to be clarified with further follow-up observations and controlled studies.

Respiratory syncytial virus(RSV)infection is a potential susceptibility factor for recurrent wheezing,which can affect the occurrence and development of asthma through immune damage,airway epithelial barrier damage,airway inflammatory infiltration,airway hyperresponsiveness,and high expression of induced susceptibility genes.Traditional Chinese medicine believes that asthma caused by RSV infection is mostly caused by the imbalance of the body's qi after infection and the retention of evil qi.By combing the mechanism of RSV infection in the occurrence and development of asthma and the research on traditional Chinese medicine intervention in recent years,it is hoped to provide ideas for the future application of combined Chinese and Western medicine to prevent and treat asthma.

Objective To investigate the predictive factors for postoperative intra-abdominal septic complications (IASCs) after intestinal resection in patients with Crohn's Disease (CD).Methods Clinical data from patients who underwent intestinal resection for CD at Sir Run Run Shaw Hospital between June 2011 and July 2016 were retrospectively analysed.The patients were divided into IASCs group and non-IASCs groups by whether suffering from postoperative IASCs.Univariate analysis and multivariate logistic regression analysis were performed to identify the predictive factors for postoperative IASCs,and the receiver operating characteristic curve (ROC) was used to analyse the diagnostic value of the results.Results Among one hundred and seventy-three patients who underwent intestinal resection for CD,15(8.7％) patients experienced postoperative IASCs.The results of univariate and multivariate analysis showed that preoperative CRP ≥ 10 mg/L (OR =4.920,95％ CI:1.137-21.287,P =0.033) was an independent trisk factor for postoperative IASCs,and the laparoscopic surgery (OR =0.070,95％ CI:0.007-0.701,P =0.024) was the independent protective factor for postoperative IASCs.By analyzing ROC curve,preoperative CRP level had the diagnostic value of predicting the postoperative IASCs.The areas under the ROC curves of preoperative CRP for postoperative IASCs were 0.729 with an optimal diagnostic cut-off value of 10.75 mg/L,and with sensitivity of 80.0％ and a specificity of 67.1％.Conclusions Preoperative CRP level is an independent risk factor for postoperative IASCs,and laparoscopic surgery is an independent protective factor for IASCs.

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.

Background Workers in the cable manufacturing industry are exposed to high-speed machinery and equipment for a long time, coupled with heavy workload, which poses significant risks to their physical health. However, the issue of occupational injuries in this industry has not received enough attention yet. Objective To understand the incidence of occupational injury of workers in cable manufacturing industry and to analyze the influencing factors. Method A basic information questionnaire and an occupational injury questionnaire were developed to investigate the occupational injuries of 1 343 workers in a cable manufacturing enterprise in the past year, and a total of 1 225 valid questionnaires were recovered, with an effective rate of 91.2%. Descriptive statistics were used to characterize the causes, injury locations, injury types, and other characteristics of employees’ occupational injuries. Chi-square test was used to analyze the occupational injury status of groups with different demographic characteristics, occupational characteristics, lifestyles, and interpersonal relationships. Logistic regression was used to analyze the influencing factors of occupational injuries. Result The incidence of occupational injuries among workers in a cable manufacturing enterprise in the past year was 8.6%, which mainly happened in male workers (80.0%) and occurred from May to July in summer (45.7%). The main causes were mechanical injuries (32.4%) and object blows (27.6%). The main sources of damage were machinery and equipment (36.2%) as well as raw materials and products (15.2%). The main injuries were located in upper limbs (53.3%) and lower limbs (22.9%). The main types of injuries were fractures (33.3%) and abrasions/contusions/puncture wounds (19.0%). The results of univariate analysis showed that there were statistically significant variations in the incidence of occupational injuries by gender, overtime, pre-job training, years of service in current position, alcohol consumption, physical exercise per week, and co-worker relationship (P<0.05). The logistic regression model showed that workers who exercised less than twice a week, did not participate in pre-job training, worked overtime, and had fair/poor/very poor colleague relationship had a higher risk of occupational injury, while women had a lower risk of occupational injury. Conclusion The distribution of occupational injury population is mainly male, and the time distribution is mainly from May to July. Gender, physical exercise, pre-job training, overtime, and colleague relationship are the influencing factors of occupational injuries. We should strengthen pre-job training, arrange work hours reasonably, and create a good working atmosphere to reduce the occurrence of occupational injuries.

Background Social psychological factors have emerged as a key area of research in occupational injury prevention. Occupational stress, a significant component of social psychology, has garnered widespread attention due to its potential impact on occupational injury. Objective To analyze the factors influencing occupational stress among cable manufacturing workers and explore the relationship between occupational stress and occupational injury, and to provide scientific evidence for reducing occupational stress and injury. Methods A questionnaire on basic demographics, occupational injury, and occupational stress (Effort-Reward Imbalance, ERI) was used to investigate 1343 workers in a cable enterprise. Chi-square test was employed to analyze the distribution of occupational stress across different worker characteristics. Logistic regression was used to identify factors influencing occupational stress, and a decision tree model was applied to assess the impact of occupational stress on injury risk. Results A total of 1225 valid questionnaires were collected, yielding a response rate of 91.2%. The positive rate of occupational stress was 28.7%, while the incidence of occupational injury in the past year was 8.6%. The results of univariate analysis revealed that workers who had experienced occupational injuries had a higher positive rate of occupational stress compared to those without injuries (P<0.05), and there were significant differences in the distribution of occupational stress by genders, overtime work, shift work, daily working hours, fatigue levels, sleep duration, family relationships, and colleague relationships (P<0.05). The logistic regression results showed that individuals who worked shifts, had fair/poor/very colleague relationships, and frequently worked overtime had a higher risk of occupational stress (P<0.05). The final decision tree model confirmed that occupational stress was a risk factor for occupational injury. Additional factors influencing occupational injury included physical exercise, colleague relationships, pre-job training participation, and gender. Workers who exercised less than twice per week and experienced occupational stress had a significantly higher risk of injury (23.6%) compared to those without occupational stress (10.9%). Conclusion Shift work, colleague relationships, and overtime work are correlated with the positive rate of occupational stress among cable manufacturing workers. Implementing a reasonable work schedule and fostering a positive work environment are recommended. Reducing occupational stress may help lower the risk of occupational injuries in this industry.

Background Diseases severely affect the efficiency of workers. Comorbidity refers to the coexistence of two or more chronic diseases or health problems in the same individual. Previous studies have primarily focused on occupational injuries caused by environmental exposures, while the analysis of the epidemiological characteristics of self-reported diseases and occupational injuries among manufacturing workers has been insufficient. Objective To analyze the distribution of self-reported diseases and occupational injuries among manufacturing workers, the strength of correlation between different diseases, and common disease combinations, and to preliminarily explore the relationship between self-reported diseases and occupational injuries. Methods A cross-sectional survey was conducted to investigate the occupational injuries of 2382 workers in 2 manufacturing enterprises over the past year, and 2355 questionnaires were valid after cleaning. The questionnaire included three parts: basic information, occupational injury occurrence, and disease prevalence. The self-reported diseases diagnosed by physicians included musculoskeletal diseases, cardiovascular diseases, respiratory diseases, mental health problems, neurological and sensory organ diseases, digestive organ diseases, reproductive and urinary organ diseases, skin diseases, tumors, endocrine and metabolic system diseases, blood diseases and birth defects, a total of 11 types. Log-binomial model was used to calculate the prevalence ratio (PR) value of the association between different diseases, and UpSet diagram was used to present the disease combination pattern. Results In total, 40.2% (946/2355) of the study participants reported at least one disease, while 8.6% (203/2355), 5.2% (122/2355), and 5.9% (140/2355) reported having two, three, and four or more diseases, respectively. A higher prevalence was observed for musculoskeletal diseases, neurological and sensory organ diseases, digestive organ diseases, and skin diseases, which accounted for 18.0% (423/2355), 13.8% (324/2355), 9.3% (218/2355), and 9.1% (214/2355), respectively. Workers with musculoskeletal disorders, cardiovascular diseases, or neurological and sensory organ diseases reported significantly higher incidence of occupational injuries compared with workers without the corresponding diseases (P<0.001, P=0.041, and P=0.006, respectively). Musculoskeletal diseases were strongly associated with comorbidities of neurological and sensory organ diseases (PR values were 1.86 and 1.98, respectively), and the other patters were musculoskeletal diseases and digestive organ diseases (PR and OR values were 1.57 and 2.35, respectively), and musculoskeletal diseases and cardiovascular diseases (PR and OR values were 1.46 and 2.22, respectively). The largest binomial comorbidity group involved musculoskeletal diseases and neurological and sensory organ diseases, accounting for 5.4% (25/465) of the comorbid workers. Conclusion Among the self-reported diseases of manufacturing workers, musculoskeletal diseases, neurological and sensory organ diseases, digestive organ diseases, and skin diseases are more common. Musculoskeletal diseases and neurological and sensory organ diseases are the most common in all comorbidities. Musculoskeletal diseases, cardiovascular diseases, and neurological and sensory organ diseases are associated with occupational injuries. In the prevention and control of occupational injuries, joint prevention strategies targeting multiple diseases should be strengthened.
