Objective To analyze the operation of Measles Surveillance System (MSS) in Hebei Province, and to provide evidence for measles elimination. Methods Measles surveillance data was collected from the MSS from 2020 to 2023, and a modified weighted technology for order preference by similarity to an ideal solution (TOPSIS) method was used to evaluate the surveillance indexes of measles in Hebei Province. Results The operation quality of the measles surveillance system in Hebei Province was improved year by year, with the highest quality in 2023, and all the indicators reached the monitoring program standards. The quality of measles surveillance system was not balanced among cities, and the main influencing factor was the substandard sensitivity indicators. The quality of measles surveillance system was the highest in Baoding City and the lowest in Zhangjiakou City. Conclusion The measles surveillance system in Hebei province is running well, and the sensitivity of the surveillance system should be improved to keep the high-quality operation of the surveillance system.

BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

OBJECTIVE: To observe the effects of enhanced rehabilitation on the prognosis of critically ill patients in the intensive care unit (ICU). METHODS: A single-center retrospective historical controlled study was conducted, patients admitted to the ICU of Peking University First Hospital from May 1, 2020, to April 30, 2021, and from October 1, 2021, to September 30, 2022 were enrolled. According to the different rehabilitation treatment strategies during different periods, patients were divided into the conventional rehabilitation group (patients receiving conventional rehabilitation treatment from May 1, 2020, to April 30, 2021) and the enhanced rehabilitation group (patients receiving the therapy of multidisciplinary team, ie medical care-rehabilitation-nursing care from October 1, 2021, to September 30, 2022). General data, acute physiology and chronic health evaluation II (APACHE II), and study endpoints were collected. Primary endpoints included rehabilitation-therapy rate, intervention time for rehabilitation, rehabilitation-related adverse events, and prognostic indicators such as (length of stay in hospital, length of stay in the ICU, and duration of mechanical ventilation). Secondary endpoints included incidence of deep vein thrombosis and hospital mortality. Kaplan-Meier curves were used to analyze cumulative discharge rates within 50 days. RESULTS: A total of 539 ICU patients were enrolled, with 245 in the conventional rehabilitation group and 294 in the enhanced rehabilitation group; 322 patients had an APACHE II score ≤ 15, while 217 patients had an APACHE II score > 15. Compared to the conventional rehabilitation group, the enhanced rehabilitation group demonstrated significantly higher rehabilitation-therapy rate [51.70% (152/294) vs. 11.43% (28/245)], earlier intervention time for rehabilitation [days: 2.00 (1.00, 3.00) vs. 4.00 (3.00, 7.00)]; shorter length of stay in hospital [days: 18.00 (12.00, 30.00) vs. 21.00 (13.00, 36.00)] and lower incidence of DVT [17.01% (50/294) vs. 24.08% (59/245)]. The differences were all statistically significant (all P < 0.05). There were no rehabilitation-related adverse events occurred in either group. Kaplan-Meier analysis demonstrated a significantly higher cumulative discharge rate within 50 days in the enhanced rehabilitation group compared to the conventional rehabilitation group [86.7% (255/294) vs. 82.9% (203/245); Log-Rank test: χ² = 4.262, P = 0.039]. Subgroup analysis showed that for patients with APACHE II score ≤ 15, the enhanced rehabilitation subgroup had higher rehabilitation-therapy rate [44.32% (78/176) vs. 6.16% (9/146), P < 0.05]. For patients with APACHE II score > 15, compared to the conventional rehabilitation group, the enhanced subgroup demonstrated higher rehabilitation-therapy rate [62.71% (74/118) vs. 19.19% (19/99), P < 0.05] and shorter length of stay in hospital [days: 20.50 (12.00, 31.25) vs. 26.00 (16.00, 43.00), P < 0.05]. CONCLUSIONS Enhanced rehabilitation therapy with medical care, rehabilitation and nursing care, improved rehabilitation-therapy rate, advanced time of rehabilitation treatment, reduced length of stay in hospital and incidence of deep vein thrombosis in critically ill patients, particularly benefited those with APACHE II score > 15. The enhanced rehabilitation was beneficial to the patient in the intensive care unit with safety and worth more investigation.

Objective To analyze the occurrence characteristics of adverse events following immunization (AEFI) of 23-valent pneumococcal polysaccharide vaccine (PPSV-23) in Hebei Province and to evaluate the safety of the vaccine. Methods AEFI cases related to vaccination of PPSV-23 in Hebei Province from January 1, 2020 to December 31, 2022 were collected through the AEFI surveillance module of Chinese Center for Disease Control and Prevention Information System. The incidence of reported AEFI cases were then analyzed and compared. Results The reported incidence rate of AEFI of PPSV-23 was 56.12 /100,000 doses, and the incidence rate of adverse reactions was 55.50 /100 000 doses. The incidence rate of common adverse reactions was 53.94/100 000 doses, and the incidence rate of rare adverse reactions was 1.56/100 000 doses. Most of the reported AEFI cases caused by PPSV-23 were common adverse reactions, which occurred mainly within one day after vaccination, and the overall regression was positive. Conclusion The 23-valent pneumococcal polysaccharide vaccine used in Hebei Province is safe，but its safety monitoring still needs to be strengthened.

Polyhydroxyalkanoate depolymerase (PHAD) can be used for the degradation and recovery of polyhydroxyalkanoate (PHA). In order to develop a PHAD with good stability under high temperature, PHAD from Thermomonospora umbrina (TumPHAD) was heterelogously expressed in Escherichia coli BL21(DE3). At the same time, a mutant A190C/V240C with enhanced stability was obtained via rational design of disulfide bonds. Characterization of enzymatic properties showed that the mutant A190C/V240C had an optimum temperature of 60 ℃, which was 20 ℃ higher than that of the wild type. The half-life at 50 ℃ was 7 hours, at 50 ℃ which was 21 times longer than that of the wild type. The mutant A190C/V240C was used for the degradation of polyhydroxybutyrate (PHB), one of the typical PHA. At 50 ℃, the degradation rate of PHB being treated for 2 hours and 12 hours was 2.1 times and 3.8 times higher than that of the wild type, respectively. The TumPHAD mutant A190C/V240C obtained in this study shows tolerance to high temperature resistance, good thermal stability and strong PHB degradation ability, which may facilitate the degradation and recovery of PHB.

Objective : To investigate the mechanism of sertoli/spermatogenic injury induced by cigarette smoke extract(CSE) based on ROS/NLRP3 signaling pathway. Methods : The sertoli/spermatogenic of rat were cultured in vitro , and they were divided into control group , cigarette Smoke extract (CSE) group and CSE + NLRP3 inflammosome inhibitor MCC950 group. Cell viability was detected by CCK⁃8 assay; Lactate dehydrogenase ( LDH) was used to detect cell membrane damage ; reactive oxygen species ( ROS) production was used to detect oxidative stress level ; Hoechst/PI fluorescent staining was used to detect cell pyroptosis. Real⁃time quantitative PCR ( RT⁃qPCR) was used to determine the mRNA level of NLRP3 , ASC , Caspase⁃1 , GSDMD , IL⁃1β and IL⁃18. Western blot was used to determine the protein level of NLRP3 , ASC , Caspase⁃1 , GSDMD , IL⁃1β and IL⁃18. Results: CCK⁃8 assay showed that cell viability decreased in CSE group (P < 0. 001) , LDH leakage rate (P < 0. 001) and ROS (P < 0. 001) production increased. Compared to the CSE group , cell viability increased (P < 0. 001) , LDH leakage rate (P < 0. 01) and ROS (P < 0. 001) production decreased in CSE + MCC950 group. The number of PI staining cells in CSE group was more than that in control group and CSE + MCC950 group , but staining cells in CSE + MCC950 group was less than that in CSE group. RT⁃qPCR and Western blot results showed that the expression levels of NLRP3 , ASC , Caspase⁃1 , GSDMD , IL⁃1β and IL⁃18 increased in CSE group but decreased in CSE+ MCC950 group. Conclusion The oxidative stress and inflammation of sertoli/spermatogenic induced by ciga⁃ rette smoke may be related to the activation of ROS/NLRP3 signaling pathway.

Background Occupational stress has become one of the main factors affecting people's physical and mental health, and there are many sources of occupational stress in petrochemical enterprises. Objective To evaluate the current situation of occupational stress and its related factors among employees in a petrochemical enterprise, and to provide a scientific basis for reduing the risk of occupational stress among employees in petrochemical enterprises. Methods In June 2022, a cross-sectional questionnaire survey was conducted in a petrochemical enterprise in Hainan, including a general information questionnaire for basic information, the Effort-Reward Imbalance (ERI) for occupational stress, and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Chi-square test was used to compare differences in positive occupational stress by demographic characteristics, occupational characteristics, behavior, and occupational disease hazards. Logistic regression was employed to evaluate factors associated with occupational stress. Results Of the 1129 questionnaire distributed, a total of 999 valid questionnaire were returned,with a valid recovery rate of 88.5%. The positive rate of occupational stress among employees in the petrochemical enterprise was 29.5%. There were statistically significant differences in the positive rate of occupational stress among the employees grouped by gender, age, marital status, body mass index (BMI), monthly income, length of service, smoking, weekly working hours, type of work, working mode, sleep quality, noise exposure, and high temperature exposure (P<0.05). In terms of positive occupational stress among subcategories: workers being male (vs. female), working ＞40 h per week (vs. ≤40 h per week), regular day shift (vs. shift work), smoking (vs. not smoking), with exposure to noise and heat (vs. without such exposure), and having poor sleep quality (vs. good sleep quality) reported higher positive occupational stress rates (P＜0.05). The results of pairwise comparison showed that the positive rate of occupational stress in divorced (50.0%) or married (32.0%) workers was higher than that in single (27.1%) workers, and higher in operation workers (30.6%) than in other types of work (20.5%) (P＜0.05). The trend chi-square results showed that the positive rate of occupational stress increased linearly with the increase of age, length of service, BMI, or monthly income (P＜0.05). The results of logistic regression analysis after adjustment showed that workers who worked ＞40 h a week had a higher risk of occupational stress than those who worked ≤40 h a week, and the OR (95%CI) was 1.909 (1.135, 3.211); the workers of other types of work had a lower risk of reporting occupational stress than operation workers, and the OR (95%CI) was 0.513 (0.272, 0.968); the workers with noise exposure had a higher risk of occupational stress than the workers without, and the OR (95%CI) was 2.457 (1.070, 5.642). Conclusion The positive rate of occupational stress among employees in this petrochemical enterprise is high. Among them, operators, working hours per week＞40 h, and noise exposure may increase the incidence of occupational stress. The enterprise should actively take measures to reduce the occurrence of occupational stress among employees.

Among the ten children, six had the clinical manifestations of hypoglycemia, and one had bilateral gastrocnemius hypertrophy and positive Gower sign. Two children had positive CMV IgG. Liver histopathological manifestations included diffuse enlargement of hepatocytes, light cytoplasm, and small nucleus in the middle like plant cells, with or without fibrous tissue proliferation. Conclusion Most patients with GSD have developmental retardation and abnormal aminotransferases, and liver pathological examination shows specific pathological features.

Objective:To explore the computer-aided navigation technology combined with personalized three-dimensional(3D) printing in the reduction and fixation of the multiple midface fractures.Methods:A retrospective analysis was performed on clinical data of patients suffering from multiple midface fractures treated at the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Anhui Medical University from August 2019 to December 2021. According to the operational method, the patients in the experimental group received the operation applied by AccuNavi-A 2.1 navigation software for surgical planning and surgical simulation, printing 3D head model before the operation, and reducing and fixing fractures with the aid of computer navigation technology. Patients in the control group received the operation applied by traditional surgery. Marking facial landmarks on the head CT 3D model of patients and constructing a spatial coordinate system before and 1 week after surgery, measuring and calculating the facial asymmetry index (AI) for each landmark, including the orbitale (O), the most outside of the zygomaticomaxillary suture of the 1/3 below of the margo infraorbitalis(MZ), the most concave point between the frontal process of zygomatic bone and the superior margin of processus temporalis(C), the most concave point of the superjacent of C of posterior margin of frontal process(SC) and the outermost point of zygomatic arch(Z). The duration of operation were recorded. Complications including diplopia, difficulty in mouth opening, facial numbness, malocclusion, scarring and pupil height were evaluated by patents 3 months after the operations. AI is represented by M( Q1, Q3), Wilcoxon rank test was used for intra-group comparison before and after operations, and Mann-Whitney U test was used for comparison between two groups. Operation time was represented by Mean±SD, and t-test was used for comparison between two groups. The result of self-assessment of patients’ complications are expressed as cases (%), and the chi-square test or Fisher’s exact test was used. Results:A total of 32 patients were included. There were 16 patients in the experimental group, 9 males and 7 females, aged 17-60 years. There were 16 patients in the control group, 8 males and 8 females, aged 18-65 years. The preoperative O, MZ, C, SC, and Z point in the experimental group were 8.9(6.9, 12.8), 10.0(7.7, 12.6), 7.6(5.9, 14.9), 10.7(7.2, 22.0), 11.2(10.1, 17.4), and 2.2(1.6, 3.4), 2.5(1.7, 3.4), 2.2(1.9, 2.9), 2.6(1.7, 3.1), 2.4(1.4, 2.8). The preoperative O, MZ, C, SC, and Z point in control group were 10.4(8.1, 12.5), 10.5(9.0, 12.6), 6.6(5.3, 8.2), 10.6(8.7, 13.1), 10.9(9.8, 13.4), and the postoperative were 4.0(3.6, 4.8), 4.3(3.8, 5.4), 5.2(4.8, 6.7), 4.3(3.1, 5.1), 4.6(3.2, 5.3). There was no significant difference in AI of each marker point between the two groups before surgery ( P>0.05). The AI of each landmark in the two groups was reduced after operation compared with that before operation to some extent ( P<0.01 or 0.05). The AI of each landmark in the experimental group was significantly lower than that in the control group( P<0.01). The operation time of the experimental group[(3.7±1.1) h] was shorter than that of the control group[(4.8±1.9) h] ( P<0.05). The incidence of scar[12.5% (2/16)] and inconsistent pupil height[6.3% (1/16)] in the experimental group was lower than that in the control group [43.8% (7/16), 37.5% (6/16)] ( P<0.05). And there was no significant difference in other items ( P>0.05). Conclusions:The computer-aided navigation technology combined with personalized 3D printing can shorten the time of operation, expedite the patients’ facial recovery with more symmetry and less likely to have complications.
