Objective:To understand the epidemiological characteristics and post-exposure prophylaxis (PEP) situation of rabies exposure population in the animal injury outpatient department of Lishui Central Hospital, so as to provide reference for rabies prevention and control in this region.Methods:The epidemiological data of 6 471 rabies-exposed persons in Lishui Central Hospital from 2021 to 2023 were retrospectively analyzed, including the gender and age of exposed persons, the month and location of injury, the species of injured animals, the exposure grade, rabies vaccination, rabies passive immunization agents, etc.Results:From 2021 to 2023, a total of 6 471 cases of rabies exposure were treated in the animal injury outpatient department of Lishui Central Hospital. From 2021 to 2023, 1 133 cases, 2 135 cases and 3 203 cases were treated respectively. April to November was the peak period of exposure. The population of 21 to 30 years had the highest rate of treatment, reaching 27.79% (1 798/6 471), and was a high-risk group of exposure. The age composition ratio of rabies exposure in the three years was statistically significantly different ( χ2=43.82, P<0.001); the male to female ratio was 1∶1.14 ( χ2=1.63, P=0.442); 3 317 cases (51.26%, 3 317/6 471) were injured by cats, and 2 614 cases (42.16%, 2 614/6 471) were injured by dogs, cats and dogs were the main injured animals ( χ2=18.63, P=0.098). The upper limbs (4 131/6 471, 63.84%) and lower limbs (1 848/6 471, 28.56%) were the most exposed sites, and there was a statistically significant difference in the exposure composition ratio of each site in three years ( χ2=105.79, P<0.001). Grade II exposure accounted for 31.79% (2 057/6 471), grade III exposure accounted for 62.31% (4 032/6 471). Among grade III exposure individuals, those who used passive immune preparations accounted for 55.13% (2 232/4 032). Conclusions:The number of rabies-exposed patients in the animal injury outpatient department of Lishui Central Hospital has been increasing year by year, and the population of patients injured by cats and dogs is particularly prominent. The utilization rate of passive immune preparations for grade III exposure patients still needs to be further improved.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

Steroid hormones play important roles in brain development and function. The signaling of steroid hormones depends on the interaction between steroid receptors and their coactivators. Although the function of steroid receptor coactivators has been extensively studied in other tissues, their functions in the central nervous system are less well investigated. In this study, we addressed the function of steroid receptor coactivator 3 (SRC3) - a member of the p160 SRC protein family that is expressed predominantly in the hippocampus. While hippocampal development was not altered in Src3

Objective:To investigate the status of height and weight of 3-18-year-old children and adolescents in urban China, and to provide a basis for establishing puberty phase specific curves for age-specific height and age-specific weight.Methods:A cross-sectional survey of 218 185 children and adolescents aged 3-18 years in urban China was conducted by using the method of stratified random cluster sampling from January 2017 to December 2019. The sampling areas included 12 provinces municipalities in China and autonomous regions in total. Data were collected on weight, height, waist circumference, hip circumference and secondary sexual characteristics. The generalized additive model for location, scale, and shape (GAMLSS) was employed to establish percentile reference values and growth curves of height and weight for boys and girls aged 3-18 years. Wilcoxon rank sum test was applied to compare the P 50 value of height and weight between children of each Tanner stage and children of the same age ignoring the different puberty phase. Results:The 3rd, 50th, and 97th percentile curves for height and weight for age were developed for boys and girls aged 3-18 years. The 3rd, 50th, and 97th percentile curves for age-specific height and age-specific weight for each puberty phase were developed for boys and girls. Compared with all children ignoring the different puberty phase, boys aged 9 and over and girls aged 7 and over who are at Tanner stage 1 showed shorter height and lighter weight than those of the same age group (all P<0.01), the difference ranges of height at P 50 are -4.0 to -0.6 cm for boys, and -4.4 to 0.5 cm for girls; the difference ranges of weight are -4.8 to 0.4 kg for boys, and -4.0 to -0.3 kg for girls; children at Tanner stage 2 & 3 initially were taller and heavier than those of the same age group; and later grew shorter and lighter than those of the same age group, the two sets of curves cross over; boys aged 16 and under and girl aged under 14 who are at Tanner stage 4 were taller and heavier than those of the same age group (all P<0.01), the difference ranges of height at P 50 are 0.2 to 10.0 cm for boys, and 0.2 to 9.4 cm for girls; the difference ranges of weight at P 50 are 0.7 to 10.9 kg for boys, and 1.0 to 11.2 kg for girls, and the differences showed narrowing trend with age. Conclusion:The puberty phase specific growth curves of age-specific height and age-specific weight for boys and girls aged 3-18 years are established, it is useful for clinical work to evaluate physical development of children at different puberty phases.

Objective:To investigate the molecular mechanism of Buyang Huanwu Tang in improving cerebral vasospasm after subarachnoid hemorrhage. Method:Eighty male Sprague-Dawley rats were randomly divided into sham operation group, model group, Buyang Huanwu Tang low and high dose (13, 26 g·kg^-1·d^-1) group. According to 10 mL·kg^-1, the drug was administered twice a day for 7 days. The subarachnoid hemorrhage model was made by double occipital pool injection method. The neurological function scores of rats in each group were evaluated at 1, 3, 5 and 7 days. The diameter of basilar artery was measured by hematoxylin-eosin (HE)staining. The expressions of phosphp-phosphoinositide 3-kinases(p-PI3K), phosphp-protein kinase B(p-Akt),endothelial nitric oxide synthase(eNOS) and neuronal nitric oxide synthase(nNOS) protein in basilar artery brain tissue were detected by Western blot. The expression of nitric oxide(NO) and endothelin-1(ET-1) in rat cerebrospinal fluid was detected by enzyme-linked immunosorbent assay (ELISA). Result:Compared with sham operation group, the neurological function scores of the model group were significantly decreased (P<0.05), the diameter of the basilar artery was significantly reduced (P<0.05), and The expression of p-PI3K, p-Akt, eNOS, nNOS proteins of the basilar artery brain tissue were significantly decreased (P<0.05). The level of NO in the cerebrospinal fluid was significantly decreased (P<0.05), and the ET-1 was significantly increased (P<0.05).Compared with model group, the different doses in Buyang Huanwu Tang group (26,13 g·kg^-1·d^-1) increased the neurological function scores 3 to 5 days after treatment, and the basilar artery diameter was significant increased (P<0.05).The expression of p-PI3K, p-Akt and eNOS protein was significantly increased (P<0.05).The level of NO was significantly increased (P<0.05), and ET-1 was significantly decreased (P<0.05). Compared with low-dose group, the neurological scores of high-dose group were significantly increased after 7 days of treatment with Buyang Huanwu Tang (P<0.05), and the diameter of the basilar artery was significantly increased (P<0.05), p-PI3K, The expression of p-Akt and eNOS protein was higher (P<0.05), the increase of NO was more obvious (P<0.05), the decrease of ET-1 was more significant (P<0.05). Conclusion:The protective effect of Buyang Huanwu Tang on cerebral vasospasm after subarachnoid hemorrhage may be related to up-regulation of p-PI3K, p-Akt and eNOS expression in PI3K/Akt/eNOS signaling pathway, thereby increasing NO production.

OBJECTIVETo explore whether fractional anisotropy (FA) value could be taken as a quantitative indicator for tracing and reexamining amyotrophic lateral sclerosis (ALS), and to analyze the correlation between FA value and integrative medical treatment.

METHODSTotally 18 ALS patients were recruited in this study. All patients received diffusion tensor imaging (DTI) using 3. OT (Propeller HD) MRI twice. Six regions of interest (ROI) were selected to measure FA values. Survival analyses were performed in 11 cases of end point events.

RESULTS(1) Three ROI (cerebral peduncle, posterior limb of internal capsule, and corona radiata) all indicated that FA value was the highest in patients with mild health status scale of amyotrophic lateral sclerosis (ALS/HSS). (2) There was statistical difference in the means of FA values in cerebral peduncle, posterior limb of internal capsule, and corona radiata of 18 cases between initial examination and reexamination (P < 0.01). (3) Kaplan-Meier survival curve showed the survival rate of ALS patients decreased as time went by, with the median survival time of 48 months.

CONCLUSIONSFA value was inversely proportional to the severity of ALS, the more severe, the lower FA values. FA value was an objective indicator for assessing the severity of ALS. ALS is an incurable disease till now. Integrative medical treatment might become one direction for ALS patients.

OBJECTIVETo assess the efficacy of vinorelbine (NVB)-based regimens in patients with metastatic triple negative breast cancer (mTNBC) pretreated with anthracyclines and taxanes.

METHODSClinical data of 48 patients diagnosed and treated for mTNBC between 2004 and 2012 at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) were retrospectively analyzed. All patients were pretreated with anthracyclines and at least one taxane in neo-adjuvant, adjuvant or chemotherapy for mTNBC and patients should be having at least one measurable metastatic lesion. Totally, 48 patients were included in this study, of which 21 cases received first-line chemotherapy and 27 cases received second-line chemotherapy. Based on the regimen they received, 22 patients were treated with NVB plus platinum (NP), and 26 patients with NVB plus capecitabine (NX).

RESULTSAfter 70 months follow-up, in the total group of patients, the objective response rate was 20.8%, clinical benefit rate was 43.8%, median progression free survival (PFS) was 4.4 months and median overall survival (OS) was 15.5 months. In addition, the ORR was significantly better in the NP arm versus NX arm (33.8% vs.7.7%, P=0.029) as well as PFS was statistically improved in the NP arm than NX arm (5.3 m vs. 3.0 m, P=0.023). Similar trend was observed in the OS, although the difference was not statistically significant (27.7 m vs. 14.8 m, P=0.077). In all, the most frequently reported adverse events were G1/2 gastrointestinal toxicity (68.8%) and neutropenia (62.5%) . No significant difference was observed between the NP arm and NX arm (P>0.05). The percentage of patients who delayed chemotherapy administration in the NP arm and NX arm was 9.1% (n=2), and 3.8% (n=1), respectively.

CONCLUSIONSNVB-based combination chemotherapy demonstrates moderate efficacy in mTNBC patients pretreated with anthracyclines and one taxane with manageable toxicity. NP regimen shows potential superiority over NX regimen, and should be further verified in randomized phase III clinical trial in larger cohort.

We observed the effect of vibration parameters on lumbar spine under different vibration conditions using finite element analysis method in our laboratory. In this study, the CT-images of L1-L5 segments were obtained. All images were used to develop 3D geometrical model using the Mimics10. 01 (Materialise, Belgium). Then it was modified using Geomagic Studio12. 0 (Raindrop Geomagic Inc. USA). Finite element (FE) mesh model was generated by Hypermesh11. 0 (Altair Engineering, Inc. USA) and Abaqus. Abaqus was used to calculate the stress distribution of L1-L5 under different vibration conditions. It was found that in a vibration cycle, tensile stress was occurred on lumbar vertebra mainly. Stress distributed evenly and stress concentration occurred on the left rear side of the upper endplate. The stress had no obvious changes under different frequencies, but the stress was higher when amplitude was greater. In conclusion, frequency and amplitude parameters have little effect on the stress distribution in vertebra. The stress magnitude is positively correlated with the amplitude.
