OBJECTIVE: To explore the clinical features of patients with necrotizing soft tissue infection (NSTI) and the related factors for sepsis, so as to provide a basis for early intervention and improvement of patients' prognosis. METHODS: A retrospective case series study was conducted to analyze the clinical data of NSTI patients admitted to the department of burns and wound repair surgery of Guangdong Provincial People's Hospital from October 2021 to December 2024. Demographic information, underlying diseases, infection characteristics, laboratory test results and etiological findings at admission, treatment status, occurrence of complications (including sepsis) and prognosis were collected. Univariate and multivariate Logistic regression analyses were used to identify the associated factors for sepsis in NSTI patients. Receiver operator characteristic curves (ROC curves) were plotted to evaluate the predictive value of individual and combined factors for sepsis. RESULTS: A total of 159 NSTI patients were enrolled, mainly middle-aged and elderly males. Most patients had comorbidities, including diabetes mellitus (110 cases, 69.2%) and hypertension (67 cases, 42.1%). The main infection site was the lower extremities (104 cases, 65.4%). Common symptoms included redness (96 cases, 60.4%), swelling (129 cases, 81.1%), local heat (60 cases, 37.7%), pain (100 cases, 62.9%), and skin ulceration or necrosis (9 cases, 5.7%). Imaging findings included soft tissue swelling (66 cases, 57.9%), gas accumulation (41 cases, 36.0%), and abnormal signal/density shadows (50 cases, 43.9%). Staphylococcus aureus was the main pathogenic bacterium [12.0% (31/259)], and drug-resistant Escherichia coli had the highest detection rate among drug-resistant bacteria [35.1% (13/37)]. Regarding debridement and repair, most patients (80 cases, 50.3%) underwent debridement ≥ 72 hours after admission, while only 10.1% (16 cases) received debridement within 6 hours. Most patients underwent multiple debridements, with 2 times of debridements being the most common (68 cases, 42.8%), and the maximum times of debridements reached 6. The largest number of patients received secondary suture (44 cases, 27.7%). In terms of complications, sepsis was the most common (66 cases, 41.51%), followed by acute kidney injury, respiratory failure requiring mechanical ventilation, and multiple organ dysfunction syndrome (MODS), while disseminated intravascular coagulation (DIC) was the least common. During the follow-up period, 9 patients (5.66%) were readmitted within 90 days, and 11 patients died, with a mortality rate of 6.92%. Univariate analysis showed that diabetes, coronary heart disease, gout, body temperature, heart rate, C-reactive protein, platelet count, total bilirubin, albumin, creatinine, out-of-hospital treatment, and out-of-hospital use of antimicrobial agents were significantly associated with sepsis in NSTI patients (all P < 0.05). Multivariate Logistic regression analysis showed that coronary heart disease [odds ratio (OR) = 30.085, 95% confidence interval (95%CI) was 2.105-956.935], C-reactive protein (OR = 1.026, 95%CI was 1.009-1.054), and total bilirubin (OR = 1.436, 95%CI was 1.188-1.948) were independent associated factors for sepsis in NSTI patients (all P < 0.05). ROC curve analysis revealed that the combination of the three predictors yielded the highest AUC for predicting sepsis in NSTI patients compared to any individual predictor [area under the curve (AUC) = 0.799 (95%CI was 0.721-0.878)]. CONCLUSIONS The clinical features of NSTI patients show certain regularity. Coronary heart disease, C-reactive protein, and total bilirubin are independent associated factors for sepsis in NSTI patients.

Objective: To investigate the spatial clustering characteristics of varicella public health emergency events in Nanjing City from 2017 to 2022, so as to provide the evidence for the development of varicella prevention and control strategies. Methods: Data of varicella public health emergency events in Nanjing City from 2017 to 2022 were collected through Emergency Public Health Management Information System of Chinese Disease Prevention and Control Information System. The software ArcGIS 10.2 was employed for trend-surface analysis, spatial autocorrelation analysis and hotspot analysis to understand the spatial clustering characteristics of varicella public health emergency events. Results: A total of 84 varicella public health emergency events were reported in Nanjing City from 2017 to 2022, with an average attack rate of 2.53% (2 558 cases). Ⅳ-level events were predominant, accounting for 90.48% (76 events). The trend-surface analysis showed lower incidence of varicella public health emergency events in the west of Nanjing City and higher in the east, and lower in the north and higher in the south. The global spatial autocorrelation analysis showed that there was a positive spatial correlation in varicella public health emergency events in 2017 and 2019, indicating spatial clustering (P<0.05). The hot spots were Jiangning District, Gaochun District, Yuhuatai District and Jianye District. Conclusion The incidence of varicella public health emergency events in Nanjing City from 2017 to 2022 has spatial aggregation, with a concentration in suburban areas such as Jiangning District and Gaochun District.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective:To investigate the effects of antibacterial absorbable suture closure in the repair of small range of bone defect wounds due to deep sternal wound infection after median thoracotomy.Methods:This study was a retrospective non-randomized clinical controlled study. A total of 32 patients (20 males and 12 females, aged (58±11) years) who met the inclusion criteria and underwent closure with antibacterial absorbable sutures (hereinafter referred to as direct closure surgery) admitted to Guangdong Provincial People's Hospital of Southern Medical University (hereinafter referred to as our hospital) from October 2017 to December 2021 were included in direct closure group. A total of 39 patients (27 males and 12 females, aged (59±11) years) who met the inclusion criteria and received bilateral pectoralis major muscle flap packing repair admitted to our hospital from January 2015 to January 2020, were included in muscle flap packing group. In the two groups, sternal infected wounds were thoroughly debrided during stage Ⅰ surgery, followed by wound repair during stage Ⅱ surgery. The width of sternal cross-section defects after debridement was less than 1 cm for patients in the two groups. For patients in direct closure group, stage Ⅱ wound repair involved intermittent sutures to the anterior sternal plate or full-thickness sternum with a total of 6 or 7 double sternal sutures. Relevant data including the duration of the stage Ⅱ wound repair surgery and the volume of blood loss during surgery, length of hospital stay, and bacterial wound infection of patients in the two groups were recorded. The postoperative complications and wound healing of patients in the two groups were recorded. During follow-up, the wound infection or recurrence of patients in the two groups and the sternal healing of patients in direct closure group were observed.Results:Compared with those in muscle flap packing group, the duration of stage Ⅱ wound repair surgery and length of hospital stay of patients in direct closure group were significantly shorter (with t values of 13.61 and 6.25, respectively, P<0.05), and there was no statistically significant difference in intraoperative blood loss volume of the stage Ⅱ wound repair surgery between the two groups ( P>0.05). The main bacterial infection in the two groups was Staphylococcus. In direct closure group, one patient had exudation in the wound two weeks post-operation, however the wound healed well after two weeks of conservative dressing changes; the wounds of the other patients healed well. In muscle flap packing group, 5 patients had postoperative complications, of which one patient died, and the wounds of 4 patients healed after dressing change or reoperation; the wounds of the other patients healed well. There was no statistically significant difference in complication incidence of patients between the two groups ( P>0.05). During the follow-up of 22-45 months, there was no re-infection or recurrence in the wound of patients in direct closure group and surviving patients in muscle flap packing group, the sternum of patients in the direct closure group achieved anatomical union. Conclusions:Direct closure surgery can not only effectively repair sternal cross-sectional defects with width below 1 cm due to deep sternal wound infections after median thoracotomy, but can also significantly shorten the operation time and duration of hospitalization.

Objective An autoregressive integrated moving average model(ARIMA)was established to predict the incidence of tuberculosis in Heze in 2022.Methods Based on the monthly registered incidence of tuberculosis patients in Heze city from 2010 to 2020,the optimal ARIMA model was established to predict the incidence in 2021 and compare with the actual value,so as to evaluate the prediction effect and predict the incidence trend in 2022.Results The incidence of tuberculosis in Heze city showed a decreasing trend year by year,with certain seasonal changes.The optimal model was ARIMA(0,1,1)(1,1,1)12,the fitting results showed that the overall prediction error rate was 2.59%and the mean absolute percentage error was 17.76%in 2021.The number of cases predicted in 2022 was 1644,which continued to show a downward trend and the epidemic situation was stable.Conclusion ARIMA(0,1,1)(1,1,1)12 model can better predict the short-term incidence trend of tuberculosis in Heze city,but it should be modified according to the changes of monitoring data to improve the prediction accuracy.

Objective:To assess the value of a model based on helicobacter pylori(Hp)status and peripheral blood levels of pepsinogen Ⅰ(PGⅠ),PGⅡ,and gastrin-17(G-17)for predicting disease progression in high-risk populations for gastric cancer.Methods:Retrospective se-lection of clinical data from 126 high-risk individuals for gastric cancer who underwent PGⅠ,PGⅡ,G-17,and C14 urea breath tests and gastro-scopy tissue biopsy at Tianjin University Jinnan Hospital from January 2023 to January 2024,Based on pathological biopsy results using gast-ric cancer tissues obtained by gastroscopy,the high-risk population for gastric cancer was assigned into normal control,precancerous lesion,and early gastric cancer groups.The diagnostic efficacies of PGⅠ,PGⅡ,G-17,C14 urea breath,and other indicators in each patient group were determined,and a predictive model was constructed.Results:The HP-positivity rate(82.35％)and PGⅡ level(22.73 ng/mL)in the early gastric cancer group were higher than those in the precancerous lesion and control groups.The PGI level(51.36 ng/mL)was lower in early gastric cancer than in precancerous lesions and control tissues.The G-17 level(5.17 pmol/L)was lower in the precancerous lesion group than in the control and early gastric cancer groups(P<0.05).Combined use of PGⅠ、PGⅡ、G-17and Hp,the area under curve(AUC)can reach 0.899,a sensitivity of 94.12％,and a specificity of 95.65％,making these factors ideal diagnostic tools for gastric cancer.According to the prediction model,the threshold for precancerous lesions was 10 points,and the critical value for early cancer was 19 points.Conclu-sions:Implementation of the C14 urea breath test combined with PGⅠ,PGⅡ,and G-17 detection in high-risk populations for gastric cancer can help monitor disease progression in high-risk populations for gastric cancer.

Objective:To analyze the current mental health status of employees in large public hospitals and its correlation with factors such as social support.Methods:A cross-sectional study was conducted in November 2023. Using cluster sampling, employees from Beijing Hospital, China-Japan Friendship Hospital, and the Cancer Hospital of the Chinese Academy of Medical Sciences were surveyed. An electronic questionnaire was used to collect indicators related to mental health. Mental health status was assessed using a self-evaluation questionnaire, with scores ≤6 indicating good mental health and scores ≥7 indicating the need for attention. A total of 3 828 questionnaires were distributed, and 3 803 valid responses were included in the final analysis. The study analyzed the current mental health status and its correlation with factors such as social support among the included employees. Social support indicators included living alone, frequency of contact with relatives or friends, and participation in group activities. Other factors included job type (physicians, nurses, medical technicians and researchers, and administrative and logistical employees), gender, professional title, education level, and satisfaction with workplace benefits.Results:The study included 3 803 respondents, comprising 874(23.0%) males and 2 929 (77.0%) females; 743 (19.5%) aged ≤30 years, 2 177 (57.2%) aged 31-45 years, and 883 (23.2%) aged >45 years. Among them, 1 238 (32.6%) employees needed attention for their mental health. The female, nurse, unmarried, post-graduate degree or less, and employees with low satisfaction with unit welfare need to pay attention to their mental health (all P<0.05), their total social support score ( t=138.59, P<0.001) and grade ( χ2=255.25, P<0.001) are lower. In terms of social support factors, non-living alone, frequent communication with relatives and friends and participation in group activities were independent protective factors for mental health (all P<0.05). The protective association between education and mental health of female workers was stronger than that of male workers (female OR=0.348, 95% CI: 0.198-0.614 vs male OR=0.653, 95% CI: 0.430-0.994). Non-living alone was the only protective factor for nurses′ mental health ( OR=0.515, 95% CI: 0.367-0.723); However, high professional title ( OR=0.362, 95% CI: 0.182-0.720) and educational background ( OR=0.365, 95% CI: 0.175-0.758) were only protective factors for physicians′ mental health (all P<0.05). Conclusions:The mental health of employees in large public hospitals is differentiated among different subgroups, such as gender, position and educational background, which needs attention in general. In terms of social support factors, non-living alone, frequent communication with relatives and friends, and participation in group activities were associated with good mental health. Hospital trade unions and other departments should carry out more targeted help and support to create a better mental health environment for employees.

The self-health management level of patients with coronary heart disease depends largely on their health literacy level. The theory of health ecology believes that the factors affecting individual health are multi-level. Based on the perspective of health ecology, this paper analyzed the influencing factors of health literacy of patients with coronary heart disease from five aspects: personal characteristics, behavior, interpersonal network, living and working conditions, environmental policies, so as to provide a basis for formulating targeted and systematic strategies for improving the health literacy of patients with coronary heart disease in the future.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.
