Objective:To analyze the epidemiological characteristics and trend of hospitalization of the patients with herpes zoster in Beijing from 2017 to 2022.Methods:In this retrospective study, the information of hospitalization of herpes zoster patients were collected from all medical institutions at the first level and above in Xicheng, Changping, and Miyun districts of Beijing. The age and gender specific hospitalization rates and age-standardized hospitalization rates were calculated. Joinpoint regression model was used to explore the trend of the hospitalization rates, and the influencing factors of the hospital stay length and complications were analyzed.Results:The age-standardized hospitalization rate of the patients with herpes zoster was 10.82/100 000-18.43/100 000 in Beijing from 2017 to 2022 [annual percent change (APC) =5.86%, 95% CI: -2.80%-15.98%]. The age-standardized hospitalization rate of the cases with herpes zoster as the main diagnosis showed an upward trend (APC=11.35%, 95% CI: 7.21%-16.23%). The age-standardized hospitalization rate showed an upward trend in women (APC=14.34%, 95% CI: 7.95%-22.37%). The hospitalization rate showed a downward trend in age group 30-39 years (APC=-24.92%, 95% CI: -48.56% - -1.85%) and showed upward trends in age group 70-79 years and 80-109 years (APC=23.18%, 95% CI: 13.53%-35.58%; APC=4.90%, 95% CI: 1.18%-9.19%). Complications occurred in 66.28% (680/1 026) of the patients. The median hospital stay length was 9 (5,15) days, and the patients with high age (≥80 years) and two or more complications had longer hospital stay, which were 12 (6, 23) and 14 (7, 27) days respectively ( P<0.001). Conclusions:The hospitalization rate in women and the elderly aged ≥70 years with herpes zoster as the main diagnosis showed upward trends in Beijing in recent years. The elderly aged ≥80 years usually had longer hospital stay, showing a relatively disease burden level. More attention should be paid to development of intervention strategies, such as vaccine, for this population.

Objective:To assess the relationship between basophil levels and mortality in patients with intra-abdominal infection.Methods:Information on patients with intraperitoneal infection admitted to the intensive care unit were extracted from the MIMIC database.A time-dependent Cox regression model was used to adjust for confounders associated with 28-day mortality.Propensity score matching(PSM)was used to balance the baseline differences be-tween groups with different basophil levels,and a restricted cube chart(RCS)was used to show the relationship between basophil count and 28-day mortality in patients with intra-abdominal infection.Results:A total of 4403 patients with intra-abdominal infection were enrolled in the MIMIC database.Patients with high basophil levels have lower mortality than those with low basophil levels.There was an L-shaped curve between basophil level and 28-day mortality,with a cut-off value of 0.47×109/L.Cox regression analysis showed that basophil levels were an independent protective factor for mortal-ity in patients with intra-abdominal infection after adjusting for potential confounders(HR=0.586,95%CI:0.443-0.769).Protective factors for death at basophil levels remained after PSM adjusted for potential confounders(HR=0.628,95%CI:0.470-0.832).Conclusion:Basophil level is an independent protective factor for mortality in patients with intra-abdominal infection,and basophil levels should be dynamically monitored to better evaluate the prognosis of patients.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To explore the genetic and environmental effects on alcohol intake.Methods:Data on 9 231 pairs of adult twins of the same sex was collected from the Chinese National Twin Registry (CNTR), between 2015 and 2018 and used in this study. Structural equation model was used to estimate the effects of genetic and environmental factors on alcohol intake.Results:A total of 9 231 pairs of twins were included in the analysis, of which 6 085 pairs were monozygotic (MZ). The average age of MZ was (36.91±13.07) years old, and males accounted for 56.80 %. The average age of dizygotic twins (DZ) was (35.22±12.48) years old, and males accounted for 55.91 %. There were 350 pairs of alcohol-drinking twins were with high-risk, accounting for 1.90 % and another 367 pairs (1.99 %) were with medium-risk. Alcohol-drinkers with medium-risk were affected by additive genetics, common and unique environmental factors, seen among the twins. The overall heritability appeared as 24.3 % (95 %CI: 0 to 56.8 %). Furthermore, 50.7 % of the variation (95 %CI: 20.4 %-79.0 %) could be explained by the common environmental factors and 24.9 % (95 %CI: 18.3 %-36.5 %) by unique environmental factors. High-risk related drinking behavior was affected by both common and unique environmental factors. The common environmental component appeared as 75.6 % (95 %CI: 69.6 %-80.8 %) and unique environmental component as 24.4 % (95 %CI: 19.2 %-30.4 %), respectively. Gender difference was seen in the heritability of those with medium or high-risk drinking behaviors. The heritability of men was 30.8 % (95 %CI: 9.8 %-53.5 %), while in women it was mainly affected by the environment. Conclusion:Both alcohol drinkers with medium and high-risk drinking behaviors were mainly affected by the environment factors and gender. With the increase of drinking volume, the effect of environment on drinking behaviors became more obvious.

Objective To analyze the present post setting situation of CDCs in Zhejiang Province, and to provide evidence for further improvement and standardization of post setting. Methods The data of post setting were collected by questionnaires from all levels of CDCs in Zhejiang Province. The compliance and rationality of post setting structure were evaluated by national and provincial normative policy documents. Results Ninety seven CDCs had implemented the post setting. Professional technical posts had the highest proportion (above 80%) among three kinds of posts. As the approved proportions of posts classification and professional titles were approved by the local government, there were differences between different levels of CDCs. The approved proportion of ground skilled posts and management posts between municipal and county CDCs had a relatively higher degree of dispersion, and the CVs of ground skilled posts and management posts of municipal CDCs were 72.3% and 65.6%, and the CVs of county CDCs were 101.6% and 82.1%. In terms of the approved professional titles structural proportion, the degree of dispersion appeared to be higher in senior titles and primary titles approved proportion of municipal CDCs (CV=29.1%, 28.5%), while the degree of dispersion was higher in senior titles and vice-senior titles of county CDCs (CV=58.9%, 21.8%) . Meanwhile, the approved proportions of senior titles in municipal and county CDCs were lower with the averages of 32.2% and 17.0%. The posts of infectious disease prevention and control and laboratory detection were accounting for the majority posts in municipal and county CDCs with average percentages of 47.8% and 45.1% . Conclusion The present situation of post structural proportion meets the relevant requirements generally. However, there are some phenomena of non-standard approved proportion of ground skilled posts and management posts and low senior titles approved proportion. Meanwhile, the percentage of infectious disease prevention and control and laboratory detection posts appears to be lower in county CDCs.

BACKGROUND: There are many methods for the treatment of femoral head necrosis, such as core decompression, bone graft, arthroplasty and joint replacement, and each of which has its own shortcomings. So, percutaneous bal oon angioplasty combined with coral artificial bone provides a new attempt for the treatment of femoral head necrosis. OBJECTIVE: To observe the effect of percutaneous bal oon angioplasty combined with coral artificial bone on femoral head necrosis repair. METHODS: Twenty-four Duroc piglets were enrol ed to establish bilateral femoral head necrosis models by liquid nitrogen freezing method. Then, model piglets were randomly treated with percutaneous bal oon angioplasty combined with injectable coral artificial bone (experimental group) or bone cement (control group) on one affected side, and meanwhile, given no treatment on the contralateral side (blank control group). At 2, 4, 8 and 16 weeks after surgery, X-ray examination, biomechanical test and histological detection were conducted. RESULTS AND CONCLUSION: X-ray showed that at 16 weeks after surgery, numerous new bones could be found in the experimental group and there was a fuzzy boundary between the artificial bone and surrounding tissues; no new bone formed in the control group, and the boundary was clear; in the blank control group, the surface of the femoral head col apsed, and bone trabeculae arranged disorderly, which were seriously destroyed. And in the histological detection at 16 weeks after surgery, there were numerous bone trabecula and osteoblasts around the coral bone in the experimental group, and the coral artificial bone almost dissolved; in the control group, bone cement was in an irregular shape and no bone trabecula formed; in the blank control group, bone trabecula were damaged in the col apsed area, whose structure was in disorder. Additional y, biomechanical changes in the experimental group were significantly better than those in the other two groups at different time points after surgery (P < 0.05). In conclusion, percutaneous bal oon angioplasty combined with coral artificial bone can repair femoral head necrosis by promoting new bone formation.
