Objective To explore the application value of heparin binding protein(HBP),neutrophil to lymphocyte ratio(NLR),lymphocyte to monocyte ratio(LMR),and platelet to lymphocyte ratio(PLR)in the evaluation of immune function reconstruction in human immunodeficiency virus(HIV)infected individuals/acquired immunodeficiency syndrome(AIDS)patients.Methods Collect 138 HIV/AIDS patients from the Outpatient Department of Hangzhou Xixi Hospital Affiliated to Zhejiang Chinese Medical University from January 1,to June 30,2023.According to CD4+T lymphocyte counts after antiretroviral treatment,categorize patients into groups with good immune function reconstruction(n=108)and poor immune function reconstruction(n=30).Compare the levels of HBP,NLR,LMR,and PLR between two groups,receiver operating characteristic(ROC)curve was used to evaluate the application value of HBP,NLR,LMR,and PLR in the reconstruction of patient immune function.Results The NLR and PLR of group with good immune function reconstruction was significantly higher than that of group with poor immune function reconstruction(P＜0.05).The LMR of group with good immune function reconstruction were significantly lower than those of group with poor immune function reconstruction(P＜0.05).The HBP between two groups was no significant differences(P＞0.05).LMR had the best efficacy in evaluating whether immune function reconstruction was good in HIV/AIDS patients area under the curve(AUC)=0.803,PLR was the second(AUC)=0.796,NLR was poor(AUC)=0.728.Conclusion NLR,LMR,and PLR are closely related to the immune function of HIV/AIDS patients and can be used as detection indicators to evaluate whether the immune function reconstruction of HIV/AIDS patients is good.

Objective: The relationship between outdoor temperature and blood pressure (BP) has been inconclusive. We analyzed data from a prospective cohort study in northwestern China to investigate the effect of outdoor temperature on BP and effect modification by season. Methods: A total of 32,710 individuals who participated in both the baseline survey and the first follow-up in 2011-2015 were included in the study. A linear mixed-effect model and generalized additive mixed model (GAMM) were applied to estimate the association between outdoor temperature and BP after adjusting for confounding variables. Results: The mean differences in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between summer and winter were 3.5 mmHg and 2.75 mmHg, respectively. After adjusting for individual characteristics, meteorological factors and air pollutants, a significant increase in SBP and DBP was observed for lag 06 day and lag 04 day, a 0.28 mmHg (95% Conclusions This study demonstrated a significant negative association between outdoor temperature and BP in a high-altitude environment of northwest China. Moreover, BP showed a significant seasonal variation. The association between BP and temperature differed by season and individuals' demographic characteristics (age, gender, BMI), unhealthy behaviors (smoking and alcohol consumption), and chronic disease status (CVDs, hypertension, and diabetes).

Objective:To explore the feasibility of emergency video call system in remote guidance of non-medical volunteers to implement single person cardiopulmonary resuscitation (CPR).Methods:A scenario of sudden cardiac arrest with a bystander in a public place was created at Clinical Skill Training Center. 60 non-medical volunteers were randomly (ramdom number) divided into video group ( n = 40) and audio group ( n = 20). Volunteers in video group were remote instructed with the smart phone application software (APP) of Emergency Video Call System to implement CPR; the audio group receives remote voice guidance for CPR with a smart phone. The pressing depth, pressing frequency, volume of ventilation and the time of the first compression were compared between the two groups. The video group was divided into 5 subgroups to compare the cardiopulmonary resuscitation effect of 5 different models of smart phones. Ten CPR cycles were observed in each group. Results:the accuracy rate of pressing position in the video group was significantly higher than that in the audio group (91.5% vs 71.35%, P < 0.05); the proportion of pressing depth in the range of 5-6 cm was significantly higher than that in the audio group (62.79% vs. 44.73%, P < 0.05); the average pressing frequency was 100-120 times / min (70% vs. 52%, P < 0.05); the ventilation volume was 500-600 mL / time (18.25% vs. 10.75%, P < 0.05); The proportion of ventilation volume greater than 500ml / min was higher than that of audio group (64.88% vs. 43%, P < 0.05). The first pressing time was longer in the video group than in the audio group (131 s vs. 106 s, P < 0.05). There was no significant difference in the first ventilation time between the two groups (148 s vs. 144 s, P > 0.05). The total pressing pause time in video group was less than that in audio group (122.4 s vs. 164.2 s, P < 0.05). There was no significant difference in the above indicators among the five different models of smart phones in the video group ( P > 0.05). Conclusions:compared with audio remote guidance, video emergency system has obvious advantages in the accuracy of pressing position, pressing depth, pressing frequency, ventilation volume and pressing pause time, but the first pressing time is slightly longer than that of audio group. The popularization and application of the video system is supposed to improve the CPR quality and recovery success rate of non-medical personnel, and facilitated to encourage the first witness to implement CPR.

Objective: To understand the incidence of stroke in the population of Jinchang Cohort and the relationship between metabolic diseases and stroke, and provide scientific evidence for the prevention and treatment of stroke in the population. Methods: The epidemiological investigation data and physical examination data of the 33 042 follow-up participants in Jinchang Cohort were collected for a prospective cohort study. Restricted cubic splines functions was used to analyze the dose-response relationship between metabolic indexes and the risk of stroke incidence. Results: 1) The incidence rate of stroke in Jinchang Cohort was 1.59%, and the standardized incidence rate was 3.99%. 2) Hypertension (male HR=2.20, female HR=4.45) and dyslipidemia (male HR=1.49, female HR=1.79) were the risk factors of stroke incidence in the population and diabetes had influence on the incidence of stroke only in the males (HR=1.79), while obesity had influence only in the females (HR=1.64). The more kinds of metabolic diseases, the higher risk of stroke incidence was. 3) Systolic blood pressure had a non-linear dose-response correlation with the risk of stroke incidence, while diastolic blood pressure had a positive linear correlation with the risk of stroke incidence. Conclusions The incidence of stroke in Jinchang Cohort population was high compared with both domestic level and oversea level. The patients with metabolic diseases were the population at high-risk for stroke, and more attention should be paid to them in the prevention and treatment of stroke. Diastolic blood pressure might be more closely related to stroke.

Objective: To investigate the incidence and rank of chronic obstructive pulmonary disease and pneumoconiosis to the workers in different occupational positions in Jinchang Cohort. Methods: In January 2014, a cohort of follow-up population in jinchang city was taken as the research object, 17843 individuals among follow-up populations in Jinchang Cohort Study, removed the individuals with chronic obstructive pulmonary disease and pneumoconiosis before 2013, and counted the new incidence individuals diagnosed by the A-Class hospital in Grade III in Jinchang City, Gansu Province, as the investigation objects to investigate the incidence rate & rank of chronic obstructive pulmonary disease and pneumoconiosis. The statistical significance was tested by chi-square test. Results: The 2-year incidence rate of Chronic Obstructive Pulmonary Disease and Pneumoconiosis in the population of Jinchang Cohort Study were 11.60‰, 13.51‰ for male and 8.46‰ for female. the ranks of 2-year incidence rates of chronic bronchitis, emphysema, pneumoconiosis and other phenotypes of chronic obstructive pulmonary disease were 7.06‰、3.42‰、0.84‰、0.34‰, respectively. Incidence rate of chronic bronchitis among administrators and executive staffs were 10.45‰; incidence rate of chronic bronchitis among service staffs were 10.45‰; incidence rate of pneumoconiosis among mining staffs were 3.44‰. Conclusion The first incidence rank of chronic obstructive pulmonary disease and pneumoconiosis in Jinchang cohort is chronic bronchitis, and the risk factors are smoking and occupational exposure.

Objective: To explore the association between fatty liver and type 2 diabetes mellitus (T2DM) in the baseline-population of Jinchang cohort study. Methods: Data from all the participants involved in the baseline-population of Jinchang cohort study was used, to compare the risks of T2DM in fatty liver and non fatty liver groups and to explore the interaction between family history or fatty liver of diabetes and the prevalence of T2DM. Results: Among all the 46 861 participants, 10 574 were diagnosed as having fatty liver (22.56%), with the standardized rate as 20.66%. Another 3 818 participants were diagnosed as having T2DM (8.15%) with standardized rate as 6.90%. The prevalence of T2DM increased in parallel with the increase of age (trend χ(2)=2 833.671, trend P<0.001). The prevalence of T2DM in the fatty liver group was significantly higher than that in the non-fatty liver group, both in men or women and in the overall population. Compared with the group of non-fatty liver, the risks of T2DM in fatty liver group were seen 1.78 times higher in males, 2.33 times in women and 2.10 times in the overall population, after adjustment for factors as age, levels of education, smoking, drinking, physical exercise, BMI, family history of diabetes and some metabolic indicators (pressure, TC, TG, uric acid, ALT, AST, gamma-glutamyl transferase). Date from the interaction model showed that fatty liver and family history of diabetes present a positive additive interaction on T2DM (RERI=1.18, 95%CI: 0.59-1.78; AP=0.24, 95%CI: 0.14-0.34; S=1.43, 95%CI: 1.21-1.69). Conclusions: Fatty liver could significantly increase the risk of T2DM and a positive additive interaction was also observed between fatty liver and family history of diabetes on T2DM. It was important to strengthen the prevention program on T2DM, in order to effectively control the development of fatty liver.

Environmental exposure to heavy metals has been linked to a wide range of human health hazards. We detected the levels of 15 metals in urine samples from 500 representative sub-samples in an ongoing occupational cohort study (Jinchang Cohort) to directly evaluate metal exposure levels. Fifteen metals, namely As, Ba, Be, Cd, Cs, Cr, Co, Cu, Pb, Mn, Ni, Se, Tl, U, and Zn, were detected by inductively coupled plasma quadruple mass spectrometry. The results showed that median creatinine adjustment and geometric mean urinary metal levels were higher in the heavy metal-exposed group, except Se and Zn, than other reported general or occupational populations. Further studies should address the effects of heavy metals on human health.

OBJECTIVETo evaluate the disease burden of colorectal cancer in Jinchang cohort, and provide evidence for preventing colorectal cancer and reducing the disease burden of colorectal cancer in the cohort.

METHODSThe colorectal cancer mortality data from 2001 to 2013 and the medical records of colorectal cancer patients from 2001 to 2010 were collected for this retrospective cohort study. The colorectal cancer disease burden was described by using mortality rate, standardized mortality rate, medical expenditure, potential years of life lost (PYLL), average potential years of life lost (APYLL), working potential years of life lost (WPYLL), and average working potential years of life lost (AWPYLL). The development trend in disease burden of colorectal cancer was analyzed by using Spearman correlation and the average growth rate.

RESULTSThe crude mortality rate of colorectal cancer from 2001 to 2013 was 9.53/100,000 with the average annual growth rate of 12.89%. The PYLL, APYLL, WPYLL and AWPYLL of colorectal cancer were 485.00 person-years, 9.15 years, 253.00 person-years, and 4.77 years, respectively. The direct medical expenditure due to colorectal cancer was 7064.38 Yuan per case and 408.43 Yuan per day. There was no increasing trend in the direct medical expenditure due to colorectal cancer.

CONCLUSIONColorectal cancer mortolity rate was on the rise and it caused heavy disease burden in Jinchang cohort.
