Investigation and management of an anaphylactic shock case after inoculation with COVID-19 vaccine / 上海预防医学

Anaphylactic shock is a serious and rare adverse reaction， which can be life-threatening if not treated in time. COVID-19 vaccine is a newly marketed vaccine， and people pay high attention to its adverse reactions. This report summarized the investigation and management process of a case of anaphylactic shock after inoculation with COVID-19 vaccine， in order to provide reference for standardizing the diagnosis and management of anaphylactic shock after vaccination.

Analysis of overseas patent registration of the classical prescription of traditional Chinese medicine / 国际中医中药杂志

Through the analysis of patent jurisprudence, it is proved that the Classical Prescription of Traditional Chinese Medicine (CPTCM) belongs to the scope of "existing technology" in the Law of Patent, and has lost the foundation of obtaining patent rights. Taking Japan's CPTCM as an example, based on the analysis of the administration of CPTCM and patent applications related to CPTCM in Japan, it is proved that CPTCM can not obtain patent authorization in Japan. Through the comparison of patent in China, the United States, Europe and worldwide region, it is proved that China is still the main source of patent applications for Traditional Chinese Medicine. At the end of the article, the author puts forward the suggestion of "active protection". It is believed that we should abandon the concept of patent-only protection and improve the influence of Traditional Chinese Medicine in worldwide from the aspects of industrial development, promotion ofits application, and intellectual property protection.

Pathogen spectrum and epidemic status of major human parasites in Chen-zhou City,Hunan Province / 中国血吸虫病防治杂志

Objective To understand the pathogen spectrum and epidemic status of major human parasites in Chenzhou City,Hunan Province,so as to provide the evidence for parasitic diseases control. Methods The survey sites were selected by the stratified cluster sampling method. The intestinal helminthic eggs were detected by Kato?Katz technique. The trophozoites or cysts of intestinal protozoa were detected by saline smear and iodine staining methods. The eggs of Enterubius vermicularis of chil?dren from 3 to 6 years old were detected by the cellophane anal swab method. The species of hookworm were identified by the fil?ter paper strip culture method. Results A total of 7 031 people were detected with the intestinal helminthic infective rate of 1.83%(129 cases). The major parasite was hookworm and there was a statistically significant difference of the infection rates among various parasites(c2=107.77,P<0.01). All the hookworm larvae were Necator americanus. No intestinal protozoon was detected. There were statistically significant differences of the infection rates among the counties(c2=25.77,P<0.01). The age of the patients was mainly focused on 30 and above years old and the infection rate was increased with the growth of age(c2=26.21,P<0.01). Farmers were the main population of the patients and there was a statistically significant difference of the in?fection rates between farmer and others(c2=29.67,P<0.01). Conclusions The infection rates of parasites are low and hook?worm is the main parasite in the pathogen spectrum in Chenzhou City. However,the infection factors still exist,therefore,effec?tive and scientific measures should be taken to consolidate the achievement.

Investigation on the iodine nutritional status among the key population in Chenzhou City, Hunan Province,2015 / 中华地方病学杂志

Objective To study the iodine nutritional status among the key population in Chenzhou City of Hunan Province,and to provide scientific basis for prevention and control of iodine deficiency disorders (IDD).Methods According to the "Hunan Iodized Salt Monitoring Pilot Scheme",total of 11 counties (cities,districts) were selected in Chenzhou City in 2015.One township was selected by east,west,south,north and center in each county (city,district).Four villages were drawn from each township,and 15 households were selected from each village to collect salt samples.Forty children aged 8 to 10 years old (half male half female) were selected from each primary school in each township.Urine samples were taken and the goiter was examined.Totally 20 pregnant women were selected from each township and urine samples were collected.The content of iodine in salt samples and urine samples were detected by the method of direct titration and As-Ce catalytic spectrophotometry,respectively.The status of goiter was detected using palpation.Results Totally 3 300 salt samples were detected in 2015,the median of salt iodine content was 25.2 mg/kg.The coverage and qualified iodized salt consumption rates were 99.61％ (3 287/3 300) and 95.30％ (3 145/3 300),respectively,which achieved the standard for the elimination of IDD.Totally 2 200 urine samples of children aged 8 to 10 years old were tested,the median of urinary iodine was 238.98 μg/L.There was variations of urinary iodine in children aged 8 to 10 years old in each county (H =32.25,P ＜ 0.01).Totally 2 200 children aged 8 to 10 years old were checked,and no goiter was found.Totally 1 100 urine samples of pregnant women were detected,the median of urinary iodine was 204.25 μg/L.There was variations of urinary iodine in pregnant women in each county (H =117.47,P ＜ 0.01).Conclusions Totally,the iodine nutritional status among the key population is appropriate in Chenzhou City.However,surveillance and health education should be continuously strengthened in the future.

Study of the RNA interference silencing of survivin gene and chemosensitivity to docetaxel in MCF-7 cells / 中国药理学通报

Aim Through interfering the expression of survivin with short hairpin RNA(shRNA) technology,to investigate the effect of downregulation of survivin on cell apoptosis and chemosensitivity to docetaxel in breast cancer MCF-7 cells.Methods(1) Using MCF-7 cells as a model system,three groups were set up transfected with lipofectamine,RNAi control plasmid and survivin RNAi plasmid,respectively.The expression of survivin in MCF-7 cells was measured at transcriptional and translational level by using RT-PCR and Western blot methods.(2) The effect on the cell cycle and apoptosis was analyzed with flow cytometry.(3) The viability of cells applied with different doses of ducetaxel was determined by using the method of 3-[4,5-Dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide reduction(MTT method).Results(1) RT-PCR and Western blot demonstrated that survivin expression was significantly decreased by transfection with RNAi targeting plasmid;the expression proportion was reduced by nearly 75.4% and 79.8%(P
