Objective: To establish a real-time quality control scheme based on the median (MD-IC) of internal control cycle threshold value in negative samples (NEG-IC-CT), so as to monitor anomalies such as progressive drift in nucleic acid testing system not covered by conventional internal quality control (IQC) in blood center nucleic acid laboratories, and to verify its feasibility. Methods: The internal control CT values of 54 426 negative samples were retrospectively collected. These samples were from four reagent batches of the two new and old equipment sets during the operation of the Wantai nucleic acid testing system in our blood center. The daily median of NEG-IC-CT values was used as the research indicator. Control limits were calculated using median absolute deviation (MAD) to construct the Median-MAD quality control chart. The monitoring performance of this scheme for the operation status of the testing system was simultaneously evaluated. Results: Statistical analysis showed significant differences in NEG-IC-CT value distribution between the new and old equipment sets, as well as between the two different reagent batches of the old equipment (P<0.000 1). The NEG-IC-CT value performance of the two different reagent batches of the new equipment was no significant difference in distribution (P>0.05). This scheme identified three typies of distinct anomalies. The out-of-control events observed with the old equipment in both the O1 and O2 reagent batches suggested potential performance decay due to equipment aging. The unreported change of reagent batch in time of Phase B with new equipment caused a stepwise drift on the quality control chart. In the later stage of Phase A with the new equipment, an alert was triggered, indicating potential quality risks associated with practices such as the mixed use of the remaining reagents and extremely long operator working hours. Conclusion: The realtime quality control scheme based on NEG-IC-CT value established in this study has been preliminarily validated for its monitoring effectiveness in nucleic acid testing in our blood center. This scheme performed well in detecting differences among testing systems and reagent batches, serving as an effective supplement to routine internal quality control. It can provide an intuitive and effective evaluation method for monitoring the performance of the nucleic acid testing process at blood center.

Objective To explore the feasibility and reference value of allogeneic lung transplantation and postoperative monitoring in miniature pigs for lung transplantation research. Methods Two miniature pigs (R1 and R2) underwent left lung allogeneic transplantation. Complement-dependent cytotoxicity tests and blood cross-matching were performed before surgery. The main operative times and partial pressure of arterial oxygen (PaO₂) after opening the pulmonary artery were recorded during surgery. Postoperatively, routine blood tests, biochemical blood indicators and inflammatory factors were detected, and pathological examinations of multiple organs were conducted. Results The complement-dependent cytotoxicity test showed that the survival rate of lymphocytes between donors and recipients was 42.5%-47.3%, and no agglutination reaction occurred in the cross-matching. The first warm ischemia times of D1 and D2 were 17 min and 10 min, respectively, and the cold ischemia times were 246 min and 216 min, respectively. Ultimately, R1 and R2 survived for 1.5 h and 104 h, respectively. Postoperatively, in R1, albumin (ALB) and globulin (GLB) decreased, and alanine aminotransferase increased; in R2, ALB, GLB and aspartate aminotransferase all increased. Urea nitrogen and serum creatinine increased in both recipients. Pathological results showed that in R1, the transplanted lung had partial consolidation with inflammatory cell infiltration, and multiple organs were congested and damaged. In R2, the transplanted lung had severe necrosis with fibrosis, and multiple organs had mild to moderate damage. The expression levels of interleukin-1β and interleukin-6 increased in the transplanted lungs. Conclusions The allogeneic lung transplantation model in miniature pigs may systematically evaluate immunological compatibility, intraoperative function and postoperative organ damage. The data obtained may provide technical references for subsequent lung transplantation research.

Objective: To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control. Methods: Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence. Results: A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk. Conclusions SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

OBJECTIVE To investigate the clinical effectiveness of triptorelin combined with Biejiajian pill in the treatment of adenomyosis （AM）. METHODS Totally 186 patients with AM admitted to Nanyang First People’s Hospital from January 2022 to October 2024 were selected as subjects and randomized into control group （n＝93） and observation group （n＝93） using the random number table method. Patients in the control group received subcutaneous injections of triptorelin acetate around the umbilicus. In addition to the treatment of control group， patients in the observation group orally administered Biejiajian pill. Both groups underwent treatment for 12 weeks and were followed up for 6 months post-treatment. The clinical efficacy， recurrence and the occurrence of adverse drug reactions were compared between the two groups. Traditional Chinese medicine （TCM） symptoms， endometrial receptivity indicators （endometrial thickness， uterine volume， endometrial resistance index and vascular index）， laboratory indexes （serum luteinizing hormone， follicle stimulating hormone， estradiol， carbohydrate antigen 125， insulin-like growth factor-1， and matrix metalloproteinase 9） were compared between the two groups before and after treatment. RESULTS A total of 164 patients completed the treatment and follow-up， among whom 80 cases were in control group and 84 cases in the observation group. The overall effective rate in the observation group was significantly higher than that in the control group， while the incidence of low estrogen levels and recurrence rate were significantly lower in the observation group compared to the control group （P＜0.05）. There were no statistically significant differences in the incidence of nausea or abnormal liver and kidney function between the two groups （P＞0.05）. After treatment， the pain Visual Analogue Scale scores， Pictorial Blood Loss Assessment Chart， TCM symptoms scores， endometrial thickness， uterine volume， endometrial resistance index， and laboratory indicators in both groups were significantly lower than those before treatment within the same group （P＜0.05）. Moreover， these values were significantly lower in the observation group compared to the control group （except for follicle stimulating hormone） （P＜0.05）. The endometrial vascular index of the two groups was significantly higher than that in the same group before treatment， and the observation group was significantly higher than the control group （P＜0.05）. CONCLUSIONS Triptorelin combined with Biejiajian pill has a definite therapeutic effect on AM， which can effectively improve the degree of dysmenorrhea and menstrual flow， improve endometrial receptivity， lower the recurrence rate in patients， and demonstrate good safety.

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.

OBJECTIVE To observe the clinical efficacy， safety and recurrence of Kuntai capsules combined with Estradiol tablets/Estradiol dydrogesterone tablets in the treatment of diminished ovarian reserve （DOR） as well as their effects on ovarian reserve function， sex hormones， and lymphocyte subsets. METHODS A retrospective analysis was conducted on the clinical data of 165 DOR patients in Nanyang First People’s Hospital. Among them， 80 patients who received Estradiol tablets/Estradiol dydrogesterone tablets （take one tablet per day according to the medication sequence on the instruction） were included in the control group， while 85 patients who additionally took Kuntai capsules （2.0 g per dose， three times daily） were included in the observation group. The treatment duration for both groups was three months. Clinical efficacy， the incidence of adverse drug reaction （ADR）， recurrence rate， and changes in Traditional Chinese Medicine （TCM） syndrome scores， ovarian reserve function indicators [anti-Müllerian hormone （AMH）， inhibin B （INHB）， antral follicle count （AFC）， endometrial thickness， and ovarian volume]， sex hormones [follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E2）]， and T lymphocyte subsets （CD3 +， CD4 +， CD8 +， and CD4 +/CD8 +） were compared before and after treatment. RESULTS The cure and significant improvement rate in the observation group was significantly higher than in the control group （82.35% vs. 65.00%， P＜0.05）. Compared to baseline levels， both groups showed significant reductions in TCM syndrome scores， FSH， LH， CD3+ and CD8+ levels after treatment， while AMH， INHB， E2， CD4 +， CD4 +/CD8 +， AFC， endometrial thickness， and ovarian volume significantly increased （P＜0.05）. The degree of improvement in these indicators was significantly greater in the observation group than in the control group （P＜0.05）. There was no significant difference in the total incidence of ADR between the two groups（P＞ 0.05）. However， the recurrence rate within six months post-treatment was significantly lower in the observation group compared to the control group （5.88% vs. 21.25%， P＜0.05）. CONCLUSIONS Kuntai capsules combined with Estradiol tablets/ Estradiol dydrogesterone tablets have a significant therapeutic effect on DOR， which can improve ovarian reserve function of the patient， regulate sex hormone levels and T lymphocyte subsets， and reduce recurrence rates， with a high safety profile.
