Objective To analyze the epidemiological characteristics of hospital admission cases with chemical poisoning in Guangdong Province from 2016 to 2020. Methods Data of hospital admissions for chemical poisoning in Guangdong Province from 2016 to 2020 were collected through Guangdong Province Health Statistics Network Reporting System，and descriptive analysis was conducted. The seasonal characteristics of the number of hospitalized poisoning cases were analyzed by the concentration method，the seasonal index（SI）was calculated by the weighted annual ratio averaging method，and the spatial auto-correlation of regional poisoning trend was analyzed by the global and local spatial autocorrelation. Results From 2016 to 2020，the number of hospital admissions for chemical poisoning in Guangdong Province was 54 656，showing a general decreasing trend. The sex ratio（male to female）was 0.90 ∶1.00. The top three types of hospitalization rates were carbon monoxide poisoning，alcohol poisoning and organic solvent poisoning. The main poisoning groups were students and children， farmers，workers and unemployed people，accounting for 31.74%，18.53%，13.91% and 10.39%，respectively. The 74.37% of poisoning cases were cured or improved and discharged，and the case fatality rate was 0.48%. The top three hospitalization rates in age group of 0-<5 years were organic solvent，metal and carbon monoxide poisoning. The hospitalization rate of carbon monoxide poisoning ranked the first among all age groups of ≥5 years. The top three regions with the highest average annual hospitalization rate were Shaoguan City （25.14/105 ），Qingyuan City （17.04/105 ） and Meizhou City （16.09/105 ）. Carbon monoxide poisoning had a strong seasonality（M=0.77），with high incidence months of January，February and December（SI were 3.60，3.08 and 2.48，respectively）. The inpatients with chemical poisoning showed non-random distribution and spatial correlation（all P<0.01），with a high-high clustering among 13 districts and counties in northern Guangdong（all P<0.05）. Conclusion The number of hospital admission cases of chemical poisoning showed an overall decreasing trend in Guangdong Province from 2016 to 2020. The main types of poisoning were carbon monoxide poisoning，alcohol poisoning and organic solvent poisoning. The spatial distribution of chemical poisoning types showed spatial correlation and there were high-high clustering areas.

OBJECTIVETo reveal the quality variation of polysaccharides, triterpenoids and proteins in spores and fruiting bodies of Ganoderma lucidum from producing areas, different varieties, harvesting parts and periods, and wall-breaking treatments.

METHODSpores and fruiting bodies from varieties of Longzhi No. 1 and Hunong No. 1 were collected as test samples, together with wall-broken spores sold in domestic main producing areas. The anthrone-sulfuric acid colorimetric method was used to determine the content of total polysaccharides. The vanillin-glacial acetic acid-perchloric acid colorimetric method was used to determine the content of total triterpenoids. The Lowry method was used to determine the content of total proteins.

RESULTThe content ranges of total polysaccharides, total triterpenoids, and total proteins from 6 domestic main producing areas were 0.40% - 2.25%, 1.36%-3.15% and 0.74% -1.91% respectively. The content ranges of total polysaccharides, triterpenoids, and proteins in the fruiting bodies from 2 varieties cultured in Zhejiang were 0.25% -1.42%, 0.44% -1.42% and 1.82% -3.67% respectively. In addition, the ranges of samples from wall-unbroken spores were 0.41% - 0.91%, 0.09% - 0.12%, 0.78% - 0.90% respectively and wall-broken spores are 1.03% - 2.25%, 1.89% - 3.15%, 0.96% - 1.04% respectively.

CONCLUSIONThere are significant differences in the contents of main chemical ingredients of wall-broken G. lucidum spores saled in the markets. The samples from Zhejiang contain high content of total polysaccharides and triterpenoids, and samples from Fujian contains more proteins. Between the 2 major varieties cultured in Zhejiang, Longzhi No. 1 contains higher content of triterpenoids, but Hunong No. 1 has more polysaccharides. Contents of triterpenoids and polysaccharides from wall-broken spores are much higher than those of fruiting bodies. The stipes from fruiting bodies contains more polysaccharides than those of the pileus, while the triterpenoids contents are higher in the pileus than stipes. The pileus and stipes collected in the second year contain higher content of polysaccharides than the first year's samples, but the contents of triterpenoids are lower. Wall-breaking treatment would significantly improve the extraction and dissolution rate of total triterpenoids and polysaccharides.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

Objective We aimed to explore the experience of posttraumatic growth in patients with cervical cancer who had a hysterectomy at the childbearing age.Methods The phenomenological methodology was used in the study.An in-depth interview was conducted among 12 patients chosen by purposive sampling method.Results Through careful analysis and collation,three themes were identified:smashing the original assumption,searching the meaning of existence and rebuilding the new cognitive schemata.The experience of patients' was conformed to the model which was put forward by Tedeschi,and the theme changes in personal relationships,personal strength,altruism born from sufferings and new philosophy of life were conformed to theoretical connotation of PTG.Conclusions Clinical medical staff should update psychological nursing concept timely and taking advantages of PTG to help patients pass through their difficult period.

Objective To determine the clinical efficacy of the combination of Aidi injection and chemotherapy in patients of advanced non-small-cell lung cancer (NSCLC). Methods One hundred and twenty three patients with stage ⅢB/Ⅳ NSCLC complying with diagnosis standard were eligible.Those patients were randomly divided into treatment group (63 patients) and control group (60 patients). Both of groups received NP regimens( NVB 25 mg/m2, ivgtt, d1,d8; DDP 25 mg/m2, ivgtt, d1-3, watering). In treatment group,patients received Aidi injection (50 ml, ivgtt, d1-10) combined with NP regimens. Then some indexes were observed, including outcomes in the overall response rates, adverse drug reaction, quality of life. Results In treatment group, outcomes in the overall response rates were 50.8 %, 5 patients were completely remitted(CR),27 patients were partly remitted(PR). In control group, outcomes in the overall response rates were 35.0 %(3 CR, 18 PR). Gastrointestinal reaction and bone marrow depression of treatment group was lower than control group. Quality of life of treatment group was higher than control group. The difference was significant between two groups (P＜0.05). Conclusion This Aidi injection plus chemotherapy combination is effective against NSCLC with mild toxicities and quality of life can be improved.
