Background Occupational stress is an important public health problem in the military. At present, there are few studies about occupational stress of officers and soldiers of the armed forces in China, especially the effects of plateau related environmental factors on occupational stress. Objective To understand current status and identify influencing factors of occupational stress among officers and soldiers stationed in plateaus, and provide a scientific basis for managing occupational stress. Methods In April 2023, stratified cluster sampling was used to recruit troops by deployed altitudes ranging from 500 to 3000 m into two strata of low altitude (＜2500 m) and high altitude (≥2500 m) based on the medical definition of plateau. Two regimental units were randomly selected from each stratum respectively, and one battalion unit was randomly selected from each regimental unit with all the officers and soldiers. Four selected battalion units were surveyed with a total of 2284 officers and soldiers. We designed a general questionnaire to collect their basic information, and distributed effort-reward imbalance questionnaires to evaluate occupational stress. We used logistic regression to identify potential influencing factors of occupational stress. Results Positive occupational stress was reported in 508 plateau-stationed officers and soldiers, with a prevalence rate of 22.2%. The total effort-reward imbalance score and the dimensional scores of effort, reward, and overcommitment in M (P₂₅, P₇₅) were 0.9 (0.7, 1.0), 16.0 (13.0, 19.0), 36.0 (33.0, 39.0), and 18.0 (15.0, 19.0), respectively. There were significant differences in the positive rate of occupational stress by gender, age, military service length, marital status, only child or not, physical fitness condition, reporting underlying diseases or not, exercise frequency before conscription, psychological changes after entering the plateaus, and having altitude sickness or not (P <0.05). The results of logistic regression showed that being female (OR=1.532, 95%CI: 1.061, 2.213), only child (OR=1.281, 95%CI: 1.038, 1.581), and with underlying diseases (OR=1.950, 95%CI: 1.340, 2.839) were associated with a higher risk of occupational stress. While setting 0 to <3 years of military service as the control group, the risk of occupational stress was higher in subgroups of 3 to 9 years (OR=1.380, 95%CI: 1.113, 1.710) and ≥9 years (OR=2.141, 95%CI: 1.461, 3.137). The participants reporting nervousness or fear (OR=1.728, 95%CI: 1.133, 2.635) and agitation or euphoria (OR=1.380, 95%CI: 1.113, 1.710) had a higher risk of reporting occupational stress than those with no psychological changes after entering the plateaus. Meanwhile, those who had regular exercise (OR=0.670, 95%CI: 0.492, 0.913) before enlistment, good physical fitness condition (OR=0.572, 95%CI: 0.426, 0.767) and excellent physical fitness condition (OR=0.502, 95%CI: 0.366, 0.688) had a lower risk of occupational stress. Conclusion Officers and soldiers in plateaus generally report a high rate of occupational stress. Female, military service length ≥3 years, being only child, with underlying diseases, nervousness/ fear or agitation/ euphoria after entering plateaus are risk factors for elevated occupational stress in this group; while good or excellent physical fitness condition and frequent exercise before enlistment are protective factors for occupational stress. Therefore, it is necessary to pay attention to the occupational stress problems in officers and soldiers stationed in plateaus and provide targeted intervention measures.

Neoadjuvant chemoradiotherapy (nCRT) followed by total mesorectal excision (TME) and adjuvant chemotherapy serves as a traditional standard treatment for locally advanced rectal cancer (LARC). However, such treatment suffers low pathological complete response (pCR) rates, which are merely less than 15%, and low anal-preservation rates, failing to meet the demand of patients for high quality of life. Recently, total neoadjuvant therapy (TNT) whereby postoperative adjuvant chemotherapy is performed preoperatively has further increased the pCR rate, gradually becoming a novel therapeutic approach. Nevertheless, the pCR rate of TNT remains below 30%. Presently, immune checkpoint inhibitors (ICIs) have been proved to be highly successful in treating various solid tumors, yet they are scarcely employed to treat LARC. In recent years, many clinical trials have been conducted to explore the application of nCRT combined with ICIs in the treatment of LARC. This paper reviews the advances in research on this therapy.

Since 2010, the incidence of severe fever with thrombocytopenia syndrome (SFTS) has been increased. Owing the progress in diagnosis and treatment, the overall mortality of SFTS in China has decreased, while the mortality in critical SFTS patients is still high. In order to provide guidance and working procedures for clinicians to diagnose and treat critical SFTS, the National Medical Center for Major Public Health Events invited experts to discuss and formulate this consensus based on their experience and up-to-date knowledge on SFTS.

Neuropeptides play an important role in the physiological functions of the human body. The physiological activities such as pain, sleep, mood, learning and memory are affected by neuropeptides. Neuropeptides mainly exist in the nerve tissue of the body, and a small amount of them are distributed in body fluid and organs. At present, analysis of large-scale identification of neuropeptides in whole brain tissue is still challenging. Therefore, high-throughput detection of these neuropeptides is greatly significant to understand the composition and function of neuropeptides. In this study, 1 830 endogenous peptides and 99 novel putative neuropeptides were identified by extraction of endogenous peptides from whole brain tissue of mice by liquid phase tandem mass spectrometry (LC-MS / MS). The identification of these endogenous peptides provides not only a reference value in the treatment and mechanism studies of diseases and the development of drugs, but also the basis for the study of a new neuropeptides and their functions.

Lesch-Nyhan syndrome(LNS) is a congenital X-linked recessive inherited disorder caused by mutations in the hypoxanthine guanine phosphoribosyl transferase (HPRT) gene.A deficiency of the HPRT enzyme is responsible for the disease.The main clinical manifestation includes hyperuricemia, juvenile-onset gouty arthritis and neurological developmental disorders.Studies have reported there are more than 400 HPRT gene mutation sites, but the incidence of LNS in the Chinese population is extremely low.Here we report a 16-year-old male patient who suffered neurological dysfunction at an early age and gouty arthritis in his youth.DNA of patient and his family members were extracted from peripheral blood lymphocytes.The coding region and the intron-exon boundaries of HPRT gene were sequenced by standard methods.We found a mutation in exon 3 of the HPRT gene of the patient and his mother (Exon3:c.143G>A), which resulted in an arginine to histidine (p.R48H) substitution in the encoded protein.No activity of the enzyme HPRT was detected in the erythrocytes.The same mutation was reported in several European families, but was found in Chinese family for the first time.Clinicians in China have poor experience in diagnosing LNS case, due to the low incidence in China.Therefore LNS screening for infants or adolescents with hyperuricemia, gouty arthritis and neurological dysfunction should be performed.

Objective To investigate the knowledge,attitude and practice (KAP) to chronic diseases and associated influencing factors in Uygur adults in Kashgar of southern Xinjiang,and provide basic information for developing ethnic specific prevention and control strategies for chronic diseases.Methods With stratified cluster random sampling,investigations,including questionnaire survey,physical examination and laboratory tests were performed among local residents who were aged ≥ 18 years and selected in Shufu county in southern Xinjiang.KAP scores were calculated and unconditional logistic regression models were used to analyze influencing factors.Results A total of 4 772 Uygur adults were surveyed.The awareness rate of chronic disease related knowledge ranged from 4.32％ to 56.04％,while the awareness rate of preventive measures were from 1.76％ to 85.18％ and the participation rate of prevention program varied from 4.00％ to 97.99％.The average KAP score was 15.90 ± 4.20 and the rate of total KAP was 47.86％.Multi-factor analysis suggested the pass rate of total KAP score increased with educational level.Other factors positively associated with ‘KAP score pass rate’ were commercial insurance investment,hypertension,family history of common chronic diseases,female and abdominal obesity,while overweight was negatively associated with the KAP score pass rate.Conclusions The KAP level on chronic diseases was low in Uygur adults in Kashgar.It is necessary to continuously implement ethnic targeted health education and health promotion campaigns,especially in low education level,low income level,overweight and male groups.

Objective To analyze the effect of carotid artery stenting (CAS) on cerebralblood flow and cerebrovascular reactivity in patients with severe carotid stenosis.Methods Twenty patients with unilateral severe internal carotid artery stenosis,conformed by carotid color ultrasonography or MR angiography in our hospital from August 2014 to December 2015,were chosen in our study.CAS was performed;relative cerebral blood flow (rCBF) detection and relative cerebrovascular reactivity (rCVR) assessment were performed by single photon emission computed tomography (SPECT) combined with carbon dioxide (CO2) inhalation within one week before surgery and 3 months after surgery.Four regions of interest (ROIs) in the bilateral middle cerebral artery (MCA) territory of internal carotid stenosis were selected for data analysis.The changes of rCBF and rCVR before and after CAS between the ipsilateral and contralateral ROIs of these patients were compared.Results In these 20 patients,80 ROIs from each patient were obtained.Preoperative ipsilateral rCBF averaged 0.883±0.075,and contralateral rCBF averaged 0.929±0.033;preoperative ipsilateral rCVR averaged 0.010±0.055,and contralateral rCBF averaged 0.124±0.053;postoperative ipsilateral rCBF and rCVR averaged 0.927±0.040 and 0.092±0.058,and contralateral rCBF averaged 0.938±0.038 and 0.127±0.054.Postoperative ipsilateral rCBF and rCVR were significantly improved as compared with preoperative ones (P＜0.05).Postoperative contralateral rCBF and rCVR were improved as compared with preoperative ones,without significant differences (P＞.05).Conclusions CAS can not only improve rCBF and rCVR of the MCA in the carotid artery stenosis,but also improve the contralateral side.

Objective: To preliminarily evaluate coronary heart disease (CAD) by dual-source CT vascular functional imaging in relevant patients. Methods: A total of 200 patients with suspected non-ST elevation acute coronary syndrome (NSTE-ACS) in our hospital from 2014-09 to 2015-10 were enrolled, 57 of them received dual-source CT angiography (DSCTA) and diagnosed for critical value of left anterior descending (LAD) stenosis; the patients were further examined by selective coronary angiography (SCA) within 1 week to conifrm the degree of stenosis. Meanwhile, fractional lfow reserve (FFR) was measured and taking FFR 0.8 as cut off point, the patients were divided into 2 groups: FFR<0.8 group,n=27 and FFR≥0.8 group,n=30. The values of left ventricular anterior wall, side wall, left ventricular cavity and the segmental thickness in diastolic and systolic stages were measured; relative CT value between ventricular anterior wall and side wall was compared, myocardium thickness at the end-diastolic stage was also compared. Results:①In FFR<0.8 group, compared with the side wall, anterior wall had decreased relative CT value (P=0.000), myocardium thickness at the end-diastolic stage (P=0.000) and myocardial wall thickening rate (P=0.001).②In FFR≥0.8 group, compared with the side wall, anterior wall had decreased relative CT value (P=0.000), myocardium thickness at the end-diastolic stage (P=0.018), while similar myocardial wall thickening rate (P=0.186).③Compared with FFR≥0.8 group, the patients in FFR<0.8group presented reduced relative CT value in anterior wall (P<0.05) and myocardial wall thickening rate (P<0.001), while similar myocardium thickness at the end-diastolic stage (P=0.964). Conclusion: CT information may provide the reference value for treating patients in clinical practice.

BACKGROUND:Lightweight polypropylene mesh with lower content of polypropylene is added with some absorbable ingredients, and wil these ingredients cause adverse reactionsin vivo?
OBJECTIVE:To compare the effect of lightweight polypropylene mesh and standard polypropylene mesh on tension-freerepair ofinguinal hernia.
METHODS:Forty patients with inguinal hernia were randomly divided into two groups (n=20 per group):the patients were treated by lightweight polypropylene mesh as experimental group andthose treated by standard polypropylene mesh ascontrol group. At 2 daysafter surgery, white blood cel counts, neutrophils percentage and level of C-reactive protein were detected. Furthermore, pain scores as wel as discomfort incidence and complications were assessed and recorded at 2 days, 1, 3 and 6 months after surgery, respectively.
RESULTS AND CONCLUSION:There were no significant differences in postoperative complications between two groups. White blood cel counts and neutrophils percentage in the experimental group were significantly lower than those in the control group (P< 0.05), butthelevel of C-reactive protein had no significant difference. Besides, pain scores had no significant differencebetween the two groups, but the postoperative discomfort incidence in the experimental group was significantly decreasedcompared with the control group (P< 0.05). In conclusion, lightweight polypropylene mesh can reduce postoperative inflammation and discomfort incidence.
