Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective:To analyze the epidemiological and clinical characteristics of respiratory syncytial virus (RSV) infection in children in Jiangsu Province from 2014 to 2023.Methods:The acute respiratory infection cases in children aged 0-14 years were selected from outpatient/emergency or inpatient departments in 2 surveillance sentinel hospitals, respectively, in Nanjing, Suzhou and Taizhou of Jiangsu from 1 July 2014 to 31 December 2023, and RSV nucleic acid test was conducted and the intensity of the RSV infection was accessed by WHO influenza epidemiological threshold method, and case information and clinical data were collected. χ2 test was used to compare the differences between groups, and the Bonferroni method was used for pairwise comparisons between groups. Results:In 4 946 cases of acute respiratory infections, the RSV positive rate was 8.21% (406/4 946), and the age M( Q1, Q3) of the cases was 1 (0, 3) years. The RSV positive rate was 10.92% (258/2 362) during 2014-2019 and 6.06% (118/1 948) during 2019-2023, the difference was significant ( χ2=31.74, P<0.001). RSV infection mainly occurred from October to March during 2014-2019, with the incidence peak in December and moderate or higher intensity. The seasonality of RSV infection was not obvious during 2019-2023, with low intensity. The RSV positive rate was highest in children in age group 0- years (17.85%, 151/846), and the positive rate declined gradually with age ( χ2=184.51, P<0.001). The RSV positive rate was higher in inpatient cases (9.84%, 244/2 480) than in outpatient/emergency cases (6.57%, 162/2 466) ( χ2=17.54, P<0.001). In the 155 RSV infection cases with complete clinical data, the clinical symptoms mainly included cough (99.35%, 154/155), fever (55.48%, 86/155), and shortness of breath (45.16%, 70/155). In the cases aged <6 months, the proportion of those with fever was low, but the proportion of those with shortness of breath, transferred to intensive care units, and receiving oxygen therapy were higher (all P<0.05). Children aged <6 months and those with underlying diseases were more likely to have severe RSV infection (all P<0.05). Conclusions:RSV infection in children in Jiangsu Province showed seasonal prevalence in winter from 2014 to 2019. Since 2020, the seasonal characteristics of the epidemic have changed, the epidemic period has been dispersed and the epidemic intensity has decreased. Infants <1 year old were at high risk for RSV infection, and those <6 months old and with underlying diseases might have severe infection.

Objective To compare the clinical safety and efficacy of CT-guided hook-wire localization of≤10mm pulmonary ground-glass nodule(GGN)via different path ways before video-assisted thoracoscopic surgery(VATS).Methods The clinical data of a total of 128 patients with 10 mm pulmonary GGN,who received CT-guided hook wire localization before VATS at The Third Hospital of Mianyang of China between July 2018 and March 2023,were retrospectively analyzed.According to the puncturing localization path way mode,the patients were divided into vertical puncturing group(n=88)and non-vertical puncturing group(n=40).The number of puncturing times,the time spent for puncturing localization,the success rate of puncture,the operation time of VATS,and puncture-related complications of the two groups were recorded.Results No statistically significant differences in the gender,age,smoking history,GGN location,puncture position,nodule size,density characteristics of GGN,emphysema,and nodules-pleura distance existed between the two groups(all P＞0.05).Compared with non-vertical puncturing group,in vertical puncturing group the number of puncturing times was smaller,the time spent for localization was shorter,the incidence of pneumothorax was lower,and the operation time of VATS was shorter,the differences in all the above indexes between the two groups were statistically significant(all P＜0.05);and the subgroup analysis of patients whose GGN was overlapped with rib shadow obtained the same results.Binary logistic regression analysis revealed that non-vertical puncturing and the number of puncturing times were the independent risk factors for the occurrence of pneumothorax.Conclusion CT-guided hook-wire localization of≤10mm pulmonary GGN before VATS is clinically safe and effective.Under the condition when the lesion can be localized within the range of 2.0cm and the shadow overlapping of GGN with the rib and blood vessel can be effectively avoided,vertical puncturing path way mode should be preferred,which can effectively reduce the incidence of pneumothorax and shorten the operation time of VATS.

Objective:To explore a simplified and efficient early prediction model for severe acute pancreatitis (SAP) using the least absolute shrinkage and selection operator (LASSO) regression, and to construct both logistic regression and decision tree models. The aim is to identify high-risk individuals, guide clinical treatment, and improve patient outcomes.Methods:A retrospective analysis was conducted on the clinical data of 412 patients with acute pancreatitis admitted to the Emergency and Gastroenterology Departments of the First Affiliated Hospital of Anhui Medical University and its High-tech Branch from November 2020 to September 2023. LASSO regression was employed to identify factors significantly associated with SAP, followed by the construction of a multivariate logistic regression model and a decision tree model. The predictive performance of these models was evaluated and compared to the bedside index for severity in acute pancreatitis (BISAP).Results:Among the 412 patients, the incidence of SAP was 12.14% ( n=50). Seven variables significantly associated with SAP severity were identified by LASSO regression, including respiratory rate at admission, pain score at admission, pleural effusion, fibrin degradation products, C-reactive protein, serum creatinine, and serum albumin. The logistic regression model incorporated four variables: pleural effusion, pain score at admission, serum creatinine, and serum albumin. In the training set, the model demonstrated a sensitivity of 0.528, specificity of 0.984, accuracy (95% CI) of 0.928 (0.892-0.955), Kappa value of 0.606, and AUC (95% CI) of 0.920 (0.862-0.979). In the testing set, the model showed a sensitivity of 0.643, specificity of 0.925, accuracy (95% CI) of 0.891 (0.822-0.941), Kappa value of 0.519, and AUC (95% CI) of 0.923 (0.861-0.985). The decision tree model comprised three branches and four terminal nodes, indicating that serum creatinine, serum albumin, and pleural effusion could effectively predict SAP occurrence. In the training set, the decision tree model had a sensitivity of 0.500, specificity of 0.973, accuracy (95% CI) of 0.914 (0.876-0.944), Kappa value of 0.544, and AUC (95% CI) of 0.812 (0.731-0.894). In the testing set, the model exhibited a sensitivity of 0.500, specificity of 0.925, accuracy (95% CI) of 0.875 (0.802-0.928), Kappa value of 0.412, and AUC (95% CI) of 0.709 (0.565-0.853). The DeLong test revealed that in the training set, the AUC of the logistic regression model was significantly greater than that of the decision tree model ( P<0.01) and the BISAP score ( P<0.001), while the AUC difference between the decision tree model and the BISAP score was not statistically significant ( P=0.762). In the testing set, the AUC of the logistic regression model was again greater than that of the decision tree model ( P<0.01) and the BISAP score ( P=0.018), whereas the AUC of the decision tree model was lower than that of the BISAP score ( P=0.017). Conclusions:Both the logistic regression and decision tree models demonstrate good predictive value for SAP, and their combined use may provide valuable guidance for clinical practice.

Objective:To compare the efficacy and safety of azacitidine combined with venetoclax or CAG regimen in the treatment of newly treated elderly patients with acute myeloid leukemia (AML).Methods:A retrospective cohort study was conducted. The clinical data of 34 newly treated elderly patients with AML treated in the Fifth People's Hospital of Datong from May 2018 to August 2023 were retrospectively analyzed. According to the treatment regimen, all patients were divided into venetoclax group (azacitidine + venetoclax, 17 cases) and CAG group (azacitidine + CAG regimen, 17 cases). The clinicopathological characteristics, efficacy, adverse reactions and survival of the both groups were compared.Results:There were no statistically significant differences in the clinical data of both groups (all P > 0.05). The complete remission (CR) rate and the objective response rate (ORR) in venetoclax group were higher than those in CAG group [CR: 70.6%(12/17) vs. 47.1% (8/17); ORR: 82.4% (14/17) vs. 64.7% (11/17)],while the differences in CR and ORR were not statistically significant (χ 2 = 2.00, P = 0.163; χ 2 = 2.00, P = 0.244). The follow-up time[ M ( Q1, Q3)] was 25.4 months (7.2 months, 60.3 months). At the end of follow-up, 19 of 34 patients survived (13 cases in venetoclax group and 6 cases in CAG group); 15 died (4 cases in venetoclax group and 11 cases in CAG group). The median overall survival (OS) time was 14.22 months (95% CI: 8.2-60.3 months) and 10.56 months (95% CI: 7.2-50.2 months), respectively in venetoclax group and CAG group;the median progression-free survival (PFS) time was 9.97 months (95% CI: 5.4-40.5 months) and 6.82 months (95% CI: 5.0-36.2 months), respectively, and there were no statistically significant differences in OS and PFS between the two groups (all P > 0.05). Grade 3-4 hematological adverse reactions occurred in 16 and 14 patients in venetoclax group and CAG group, respectively. There were no significant differences in granulocyte deficiency time, platelet deficiency time, infection and bleeding incidence between the two groups (all P > 0.05). Conclusions:Azacitidine combined with venetoclax or CAG regimen have better clinical efficacy and safety for newly treated elderly patients with AML.

BackgroundChronic obstructive pulmonary disease （COPD） is a common chronic respiratory disease， and patients with COPD often experience substantially emotional difficulties， such as anxiety and depression， all of which may cause serious detriment to the prognosis of patients. As a non-pharmacological intervention in clinical practice， group mindfulness-based stress reduction therapy （MBSR） is beginning to emerge， while has rarely been studied in COPD patients with concurrent emotional difficulties. ObjectiveTo evaluate the effects of group MBSR on depression， state of mindfulness and pulmonary function in stable COPD patients， so as to provide references for the application of group MBSR in patients with COPD. MethodsA total of 97 patients with stable COPD who were followed up in the Department of Respiratory and Critical Care Medicine of Mianyang Third People's Hospital from January to October 2019 were selected as the study objects， and they were assigned into study group （n=50） and control group （n=47） by random number table method. All individuals received routine medication therapy and an 8-week health education， based on this， participants in study group partook an 8-week intervention comprising group MBSR. At the baseline， 4 weeks and 8 weeks of intervention， participants were assessed with Self-rating Depression Scale （SDS）， Five Facet Mindfulness Questionnaire （FFMQ） and COPD Assessment Test （CAT）， as well as the pulmonary function testing. ResultsThere were 41 patients in study group and 42 cases in control group completed the study. The group * time interaction was interpreted as significant between two groups for SDS， FFMQ and CAT scores （F=54.858， 86.161， 69.862， P<0.01）. Baseline SDS， FFMQ and CAT scores of the two groups yielded no statistical difference between two groups （F=0.240， 0.052， 0.019， P>0.05）， while study group scored lower on SDS and CAT （F=12.900， 38.511， 7.797， 28.824， P<0.01） and higher on FFMQ （F=27.324， 82.412， P<0.01） than those of the control group after 4 and 8 weeks of intervention. With the prolongation of intervention time in study group， participants demonstrated an overall reduction in SDS and CAT scores （F=109.753， 124.144， P<0.01）， and an increase in FFMQ scores （F=228.194， P<0.01）. There were no between-group differences in forced expiratory volume in one second as percentage of predicted volume （FEV1%pred） after 4 and 8 weeks of intervention （F=0.104， P=0.748） ， and the within-group changes in FEV1%pred value over the intervention period in study group was not statistical （F=0.561， P=0.458）. ConclusionGroup MBSR may help relieve depressive symptoms， enhance mindfulness level， and alleviate clinical symptoms in stable COPD patients， but has no effect on pulmonary function. ［Funded by Mianyang Health and Health Commission Scientific Research Project （number， 201916）］

【Objective】 To investigate the current situation concerning volume control of red blood cells in additive solution produced by blood service in Chongqing, and to lay a foundation for promoting the homogenization of preparation process of red blood cells in additive solution. 【Methods】 A questionnaire was designed to investigate the factors related to the preparation of red blood cells in additive solution. The questionnaire was sent by Chongqing Association of Blood Transfusion via E-mail to 18 blood services in the city, and the collected data was sorted, revised and analyzed by research team. 【Results】 A total of 18 blood services(including 1 blood center + 1 sub-center, 6 central blood stations and 11 central blood banks) returned the questionnaires. The results showed that there were differences among blood services across Chongqing, regarding the centrifugal parameters during preparation, the operation mode and monitoring situation of the capacity control during preparation, and the formulation of the capacity standard of red blood cells in additive solution etc. 【Conclusion】 The preparation process of red blood cells in additive solution, produced by Chongqing blood services, should be further standardized, and the capacity control method of this product in Chongqing should be gradually unified to achieve regional homogeneity and to ensure blood safety.

Objective    To analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. Methods    We reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results     Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). Conclusion    Staged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.

Objective:To investigate the expression of zinc finger protein 580 (ZNF580) in oxygen-glucose deprivation (OGD) model of SH-SY5Y cell line and its overexpression on the apoptosis of hypoxic-ischemic neurons and the possible mechanism.Methods:The study was divided into two parts: (1) Human neuroblastoma SH-SY5Y cell line was cultured and divided into the model group and control group. The model group was incubated at 37 ℃ for 6 h in a three-gas incubator of 95% N 2, 5% CO 2, and 0.1% O 2 to establish OGD model, and proteins were extracted at 6, 12, and 24 h after OGD. The expression of ZNF580 was quantified by Western blot. (2) Effects of ZNF580 overexpressed with lentivirus transfection on the apoptosis and cleaved caspase-3 expression: Cells were collected from the control group and model group 24 h after OGD. Overexpressed ZNF580 cells were constructed by lentivirus transfection as the overexpression group and then treated with OGD. Flow cytometry was used to detect the apoptosis rate in the three groups and Western blot was used to detect the expression of cleaved caspase-3. Two independent sample t-test, one-way variance analysis, and LSD- t for pairwise comparison were used for statistical analysis. Results:(1) ZNF580 expression was significantly increased at 6, 12, and 24 h after OGD compared with the control group (1.36±0.05, 2.12±0.07, 1.69±0.05 vs 1.00, LSD- t=9.20, 28.26, and 19.21, all P<0.001). (2) Apoptosis rates of the control, model, and overexpression groups were (1.07±0.56)%, (21.51±1.65)%, and (3.42±0.93)%, respectively, and relative expression levels of cleaved caspase-3 were 1.00, 2.47±0.59, and 1.70±0.25, respectively. Compared with the control group, apoptosis rate and cleaved caspase-3 relative expression level were significantly increased in the model group (LSD- t=21.98 and 8.17, both P=0.001), while the two figures were significantly decreased in the overexpression group when compared with the model group (LSD- t=19.45, P=0.001; LSD- t=4.28, P=0.005). Conclusion:Hypoxia and ischemia could lead to the overexpression of ZNF580, which may reduce the apoptosis of hypoxic-ischemic neurons by inhibiting the expression of cleaved caspase-3 and affecting its enzymatic activation.

【Objective】 To pilot an informed consent audit system for clinical transfusion in a large tertiary hospital, so as to provide evidence and recommendations to improve the consent system. 【Methods】 A report table containing key items of transfusion informed consent such as transfusion risk, transfusion benefit and alternative treatment was developed in compliance with the national guidelines and regulations, and issued to a total of 206 patients with records on red blood cell transfusion from April 1 to June 30, 2019 in a tertiary hospital. 【Results】 The audit results showed that 98.06% (202/206) of transfusion informed consents were signed by patients, but only 65.05% (134/206) were signed by doctors. 31.07% did not record the reasons for transfusion, and 46.6% did not record the transfusion plan. 99.31% of the doctors participated in the audit claimed that the patients were informed of the risk of blood transfusion, but only 79.8% (158/198) patients recalled that the doctors mentioned the risk. Although 80.5% (116/198) of the patients were informed of alternative treatment, only 28.79% (57/198) recalled being told about alternative treatment. Allogeneic blood transfusion was the most frequently choice for patients recommended by doctors, accounting for 98.61% (142/144). However, only 48.99% (97/198) of patients could recall allogeneic blood transfusion. 80.5% of the patients recalled being informed of alternative treatment plans, and only 28.79% of the patients recalled being offered alternative treatment plans. Only 43.43% of the patients considered themselves as the main participants in decision-making of blood transfusion. In terms of training, 82.64% (119/144) doctors described having attended training programs. 【Conclusion】 The written consents for blood transfusion in our hospital were not well recorded. Patients received less information of blood transfusion informed by the doctors and did not fully participant in the decision-making of blood transfusion. There is a gap between the practice and the current national guidelines and regulations. The audit results indicated that it is necessary to further strengthen the professional knowledge of clinicians and communication skills between the doctors and patients. This audit results in this study will provide recommendations for further transfusion informed consent audit and continuous improvement of clinical transfusion informed consent practice in China in the future.
