Objective To analyze the epidemiological characteristics of food poisoning deaths in Wenshan Prefecture of Yunnan Province from 2010 to 2019, so as to provide the basis for formulating the strategies and measures for prevention and control of food poisoning deaths in Wenshan Prefecture. Methods The data of food poisoning deaths in Wenshan Prefecture from 2010 to 2019 were collected and analyzed by Excel software. Results From 2010 to 2019, 65 food poisoning deaths were reported, accounting for 7.5% of the food poisoning incidents in the same period.The fatality rate of food poisoning deaths was 36.7%, and the mortality rate of food poisoning events in the same period was 2.1%.The high incidence of food poisoning deaths occurred in summer and autumn, with the highest in June and July.Wild mushroom poisoning was the main cause of death in food poisoning, and the incidence was mainly in rural families. Conclusion Wild mushroom poisoning should be the focus of controlling food poisoning deaths in Wenshan Prefecture.It is necessary to strengthen public education, improve people′s ability to identify edible wild mushrooms, strengthen the building of capacity of medical institutions in towns and villages, and establish a long-term mechanism for food safety management.

OBJECTIVETo establish the HPLC fingerprint of Radix Aconiti Kusnezoffii.

METHODThe chromatographic separation was performed on a Kromasil C18 (4.6 mm x 250 mm, 5 microm) eluted with a mobile phase of acetonitrile-ammonium acetate buffer (2. 5 per thousand acetic acid-ammonia pH 10.5) (60:40). The UV detection wavelength was set at 240 nm and the flow rate was set at 1.0 mL x min(-1).

RESULTThe RSD of precision and repeatability was less than 2%. Under the selected chromatographic conditions, good HPLC fingerprints of Radix Aconiti Kusnezoffii were obtained.

CONCLUSIONThe method was simple, accurate and repeatable. It can be used for the quality control of Radix Aconiti Kusnezoffii.

Objective:To observe the clinical effects of modified Maxing Shigan Decoction combined with acupoint application of Traditional Chinese Medicine (TCM) on inflammatory indicators and pulmonary function in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with syndrome of phlegm-heat accumulated in the lung.Methods:Prospective cohort study. Eighty AECOPD patients with syndrome of phlegm-heat accumulated in the lung, who met the inclusion criteria in our hospital from October 2020 to January 2022 were included, and randomized into two groups by random number table methods, 40 in each group. The control group received conventional therapy of Western medicine, while the treatment group received modified Maxing Shigan Decoction combined with acupoint application of TCM on the basic treatment of control group. Both groups were treated for a course of 14 days. The white blood count (WBC) and percentage of neutrophil (NE%) were detected by automatic blood cell analyzer. Levels of C-reactive protein (CRP) were measured by enzyme linked immunosorbent assay (ELISA). Pulmonary function parameters including forced expiratory volume in one second (FEV1), percentage of forced expiratory volume in one second (FEV1%), forced vital capacity (FVC) and FEV1/FVC were detected by spirometry. Meantime, the adverse reactions and clinical responsive rate were recorded in both groups.Results:The overall responsive rate was 90.0% (36/40) in treatment group, which had statistically significant difference with 70.0% (28/40) in control group (χ 2=5.00, P=0.025). After treatment, plasma WBC [(4.15±1.02)×10 9/L vs. (7.53±1.27)×10 9/L, t=13.12], NE% [(0.50±0.12)% vs. (0.65±0.13)%, t=5.36] and serum CRP [(8.12±5.58)mg/L vs. (25.15±8.50)mg/L, t=10.59] in the treatment group were significantly lower than those in the control group ( P<0.05). The FEV1 [(1.94±0.23)L vs. (1.71±0.35)L, t=3.47], FEV1% [(88.25±9.21)% vs. (74.10±8.13)%, t=7.29], FVC [(3.85±0.31)L vs. (3.12±0.23)L, t=12.29] and FEV1/FVC [(86.12±7.18)% vs. (75.30±8.32)%, t=6.23] in the treatment group were significantly higher than those in the control group ( P<0.05). The adverse reaction rate during treatment period yielded no significant difference between two groups ( P>0.05). Conclusion:Application of modified Maxing Shigan Decoction combined with acupoint application of TCM in the treatment of AECOPD with syndrome of phlegm-heat accumulated in the lung can effectively attenuate inflammation response and ameliorate the pulmonary function.

Objective:To evaluate the clinical efficacy of Jiawei Zhixiao Decoction and western medicine comprehensive therapy in acute attack of bronchial asthma of heat asthma syndrome.Methods:Randomized controlled trial. A total of 80 patients with acute exacerbation of bronchial asthma and TCM pattern heat asthma, who treated in the respiratory department of our hospital from January 2021 to December 2021, were selected. Accordlty to random number table method the patients were divided into the treatment group and control group, with 40 in each group. The patients in the control group were given comprehensive treatment of Western Medicine (bronchodilator and glucocorticoid, etc.). On the basis of comprehensive treatment of Western medicine, the treatment group was combined with Jiawei Zhixiao Decoction. All patients received a 14-day treatment. Before and after treatment, the TCM symptom scores were recorded, FEV1 and forced expiratory volume in one second to forced vital capacity ratio (FEV1/FVC) were measured by pulmonary function meter, and peak expiratory flow (PEF) was measured by peak expiratory flow meter. Serum TNF-α and IL-8 levels were detected by ELISA, and procalcitonin (PCT) was detected by electrochemiluminescence. The disease grade, clinical efficacy and adverse reactions were also recorded.Results:The total effective rate was 95.0% (38/40) in the treatment group and 80.0% (32/40) in the control group, the difference between the two groups was statistically significant ( χ2=4.11, P=0.043). After treatment, the TCM symptom score of the treatment group was significantly lower than that of the control group ( t=7.91, P<0.01). FEV1 [(2.83±0.37) L vs. (2.38±0.32) L, t=6.77], FEV1/FVC [(85.37±9.36) % vs. (75.50±10.24) %, t=4.50], PEF [(4.84±0.82) L vs. (3.92±0.43) L, t=6.28] was significantly higher than that of control group ( P<0.01). Serum IL-8 [(80.59±10.28) ng/L vs. (87.15±8.25) ng/L, t=3.15], TNF-α [(43.18±4.08) ng/L vs. (51.78±7.58) ng/L, t=6.32], PCT [(0.84±0.35) μg/L vs. (0.41±0.12) μg/L, t=7.35] were significantly lower than those in control group ( P<0.01). The improvement of asthma grade was significantly better than that of control group ( Z=17.86, P<0.05). During the observation period, there were no serious adverse reactions in both groups, and the safety was high. Conclusion:Application of Jiawei Zhixiao Decoction and western medicine comprehensive therapy in acute attack of bronchial asthma of heat asthma syndrome can effectively improve the TCM symptoms and lung function, attenuate the inflammation response, and alleviate the severity of asthma.
