Objectives:To evaluate the effect of partial parenteral nutrition(PPN) with fat emulsion on liver function and energy metabolism in patients with liver cirrhosis. Methods:67 cirrhotic patients were divided into two groups randomly and given PPN with(group 1, 33 cases) or without(group 2, 34 cases)fat emulsion for two weeks separately.Their liver function test,fasting blood glucose(FGB) and insulin(Ins) and postprandial blood glucose at 2nd hour (PPBG 2 h),lipid metabolism and arteral ketone body ratio(AKBR) were examined respectively before and after PPN. Results:Having been given PPN for two weeks,ALT and TB levels were decreased in group 1( P 0.05 ). Alb level was decreased in group 2( P 0.05). TG,CH and PL levels were normal in group 1( P 0.05).AKBR was increased in group 1( P

OBJECTIVE:To study the antitumor activity and immunomodulatory effects of theasinesin on mice transplanted tumor and tumor-bearing mice.METHODS: With three mice transplanted tumor models i.e. Ehrlich ascites tumor, sarcoma 180 and hepatic carcinoma H22,we strdied the antitumor activity of theasinesin .The immunomodulatory effects of theasinesin on S180-bearing mice were measured by delayed type hypersensitivity(DTH), cleaning charcoal particles method, and splenocyte proliferation test .RESULTS: Theasinesin at doses of 400,200, 50mg/kg could markedly inhibite the growth of Ehrlich ascites tumor(solid tumor) .Although theasinesin didn't have significant inhibitory effects on sarcoma 180 and hepatic carcinoma H22 in routine oral administration, the average inhibitory rates of each group, in manner of preventive administration, were all greater than 30% .Theasinesin at doses of 50,100,200mg/kg could significantly restore the decreased DTH in S180-bearing mice. It could also markedly increase K, a and promote proliferation of activated T cells in S180- bearing mice. CONCLUSION :Theasinesin has significant inhibitory effects on mice transplanted tumors. It can also enhance the decreased immunological function on tumor-bearing mice.

Objective: To preliminarily evaluate the clinical efficacy of endoscopic argon plasma coagulation (APC) combined with sub-mucosal injection of norepinephrine saline in the treatment of radiation proctitis (RP), especially for refractory RP. Methods: Clinical data of 22 RP patients were retrospectively analyzed. The severity of RP was evaluated by a modified endoscopy scoring system (A) or Sherman′s classification (B). The criteria of successful treatment are the improvement of clinical symptoms or the cessation of bleeding (or only occasional traces of blood on the stools that do not need further treatment). Results: All 22 patients were successfully treated. Among them, 18 patients (82%) had no bleeding. According to the classification of A, 15 patients (68%) had mild proctitis and 7(32%) experienced severe proctitis. Based on B classification, 9 patients (41%) were categorized as mild proctitis and 13(59%) as severe proctitis. Using the classification of A, the number of treatment sessions was significantly correlated with the endoscopic grade (or endoscopic total score)(Spearman’s r=0.86, P<0.001). Conclusions Preliminary evidence demonstrates that endoscopic APC combined with sub-mucosal injection of norepinephrine saline is not only effective for mild and moderate RP, but also maintains long-term efficacy for refractory RP. Modified endoscopy scoring system (A) assessment is more suitable for clinical application compared with B assessment.

Background Injury is a major public health issue, and studying the correlation between temperature and injury in the context of climate change is of great significance for injury prevention and control. Objective To analyze the association between temperature and the volume of emergency medical service response due to injury in Chengdu. Methods Using a retrospective ecological study design, weather data in Chengdu were collected from 1 January 2022 to 31 December 2023 from Chengdu Meteorological Office, including daily average temperature, daily average relative humidity, average wind speed, average pressure, sunshine, and rainfall. Emergency medical service data were collected from an emergency medical service center in Chengdu. A distributional lag non-linear model was conducted to calculate the association between temperature and volume of emergency medical service response due to injury, and gender- and age-stratified analyses were followed to identify susceptible groups. Results Overall 219685 incidents of emergency medical service dispatching due to injury were collected during the study period. The top three injury causes were traffic accident (90765, 41.32%), poisoning (44101, 20.07%), and falling (44046, 20.05%). When daily average temperature exceeded 17.9 ℃, as the temperature rised, the volume of emergency medical service response for injury increased. In terms of the single-day lag effect, the risk of emergency medical service response for injury elevated on lag1 and persisted until lag6, the maximum daily effectwas observed on lag2, lag3 and lag4, and their relative risks associated with every 1℃ higher above 17.9 ℃ were both 1.08 times, 95%CIs were (1.03, 1.14), (1.04, 1.12), and (1.04, 1.16) respectively. Both men and women were susceptible to temperature, but on the same lag day, the men's RR value was higher than the women's. There was no statistical difference in the lag effect of temperature on the 0-17 age group; the lag effect on the 18-44 age group appeared on lag1, and lasted to lag6; that for the 45-64 age group appeared on lag1, and lasted to lag4; that for the 65 age group and over was only on lag 3 (RR: 1.05, 95%CI: 1.00, 1.10). Conclusion As the temperature rises, the volume of emergency medical service response due to injury is increased in Chengdu. In particular, the associated impact is significant on males and people aged 18-44 years old.

OBJECTIVES: The association between concentrations of sulfur dioxide (SO), nitrogen dioxide (NO), carbon monoxide (CO), ozone (O), and emergency ambulance dispatches (EADs) for asthma was explored in the central Sichuan Basin of southwestern China for the first time. METHODS: EADs for asthma were collected from the Chengdu First-Aid Command Center. Pollutant concentrations were collected from 24 municipal environmental monitoring centers and including SO, NO, CO, daily 8-h mean concentrations of O (O-8 h), and particulate matter less than 2.5 μm in aerodynamic diameter (PM). The climatic data were collected from the Chengdu Municipal Meteorological Bureau. All data were collected from years spanning 2013-2017. A time-stratified case-crossover design was used to analyze the data. RESULTS: After controlling for temperature, relative humidity, and atmospheric pressure, IQR increases in SO (13 μg/m), NO (17 μg/m), and CO (498 μg/m) were associated with 18.8%, 11.5%, and 3.1% increases in EADs for asthma, respectively. The associations were strongest for EADs and SO, NO, and CO levels with 3-, 5-, and 1-day lags, respectively. CONCLUSIONS This study provides additional data to the limited body of literature for potential health risks arising from ambient gaseous pollutants. The results of the study suggest that increased concentrations of SO, NO, and CO were positively associated with emergency ambulance dispatches for asthma in Chengdu, China. Further studies are needed to investigate the effects of individual air pollutants on asthma.

BACKGROUND: There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden. METHODS: Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status. RESULTS: A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status. CONCLUSIONS Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.
