This article systematically analyzes the historical evolution of the name， origin， scientific name evolution， medicinal parts， producting area， harvesting and processing， clinical efficacy of Paridis Rhizoma by consulting the ancient materia medica， medical books and prescription books， combined with modern literature， in order to provide a reference for the development of famous classical formulas containing Paridis Rhizoma. According to research， it can be verified that Paridis Rhizoma was first recorded in Shennong Bencaojing with the name of Zaoxiu， and this name has been used for ancient materia medica in the past generations. The name of Chonglou was first appeared in Xinxiu Bencao of the Tang dynasty， and has gradually become the rectification of name， with it being the correct name in modern legal names at all levels. The mainstream source of Paridis Rhizoma used in ancient times was the dried rhizomes of Paris polyphylla var. chinensis， but due to the similarity plant morphology of the genus Paris， there was much confusion， and the same genus of plants with thick rhizomes were also used as Paridis Rhizoma， such as P. polyphylla， P. polyphylla var. stenophylla. Since modern times， P. polyphylla var. yunnanensis has also been included as one of the mainstream sources of Paridis Rhizoma. The origin recorded in ancient materia medica are mainly in Shandong， Anhui， Jiangsu， Jiangxi， Yunnan and other regions， which are collected in the wild for medicinal purposes， modern cultivation is more prevalent in southwestern regions， such as Yunnan， Sichuan， Guizhou and Guangxi. In ancient times， the harvest time was mostly root harvesting in April and May of the lunar calendar， while in modern times， they are mostly harvested throughout the year or in autumn. Autumn harvesting is the best choice， with roots removed from the production area， washed， and dried in the sun. In ancient times， Paridis Rhizoma was processed by baking， grinding and other methods， but in modern times， sliced raw products were mainly used as medicine. Paridis Rhizoma has a slightly cold nature， a bitter taste， and a small toxicity. It can regulate the liver meridian， clear heat and detoxify， reduce swelling and pain， cool the liver and calm convulsions. It is used for symptoms such as boils and carbuncles， throat swelling and pain， snake and insect bites， and its flavor and efficacy are basically consistent in ancient and modern records. Based on the results of the textual research， it is recommended that the dried rhizomes of P. polyphylla var. chinensis or P. polyphylla var. yunnanensis should be used in the development of famous classical formulas containing Paridis Rhizoma， the processing method is selected according to the requirements of the formula， and the raw product is recommended to be used as medicine if not specified.

This article systematically analyzes the historical evolution of the origin， scientific name， medicinal parts， quality evaluation， harvesting and processing and other aspects of Tsaoko Fructus by consulting ancient materia medica， medical books， prescription books in the past dynasties and combining with the modern literature， so as to provide a basis for the development and utilization of famous classical formulas containing Tsaoko Fructus. According to the research， the name of Caoguo（草果） was first used in the Taiping Huimin Heji Jufang（《太平惠民和剂局方》） in the Northern Song dynasty， Tsaoko Fructus is the correct name of the herbal medicine in all dynasties， and there are also aliases such as Caokou， Doukou， Loukou， Laokou and Caodoukou. The mainstream source of Tsaoko Fructus used in the past dynasties is the dried mature fruit of Amomum tsaoko of Zingiberaceae， but Tsaoko Fructus was often used as a nickname for Amomi Fructus Rotundus or Alpiniae Katsumadai Semen during the Song dynasty. Bencao Pinhui Jingyao（《本草品汇精要》） in the Ming dynasty was the earliest materia medica that recorded Tsaoko Fructus as a separate medicinal herb in sections. Under the influence of early ancient books， there were some books that confused Tsaoko Fructus with other Zingiberaceae plants during the Qing dynasty， it was not until modern times that Tsaoko Fructus was distinguished from other plants. The origin of Tsaoko Fructus is Yunnan and Guangxi， and then gradually expanded to Guizhou and other places. Now Yunnan is the province with the largest planting area of Tsaoko Fructus， and has become the main producing area. Since modern times， it has been recorded in the literature that the quality of Tsaoko Fructus is mainly characterized by large， full， red-brown and strong in smell. According to ancient records， the harvest time of Tsaoko Fructus was in the eighth month of the lunar calendar， and they were mostly used for peeling or simmering. Currently， the harvest period of Tsaoko Fructus is October to November， and then sun-dried or dried after harvesting. The records of the properties and functional indications of Tsaoko Fructus are basically consistent with the ancient and modern documents， which is warm in nature， pungent in flavor， belonging to the spleen and stomach meridians， moderate in dryness and dampness， intercepting malaria and eliminating phlegm， used for internal resistance of cold and dampness， abdominal distension and pain， fullness and vomiting， malaria cold and fever， and plague fever. Based on the research results， it is suggested that A. tsaoko should be used as the medicinal base for the development of famous classical formulas containing Tsaoko Fructus， processing method can be according to the requirements of the prescription， and if the requirements of concoction are not indicated， it can be used in the form of raw products.

Objective To evaluate the potential risk of transmission of angiostrongyliasis by common freshwater snails in Dali Bai Autonomous Prefecture, Yunnan Province, so as to provide insights into local surveillance of angiostrongyliasis. Methods Common freshwater snails were collected from Dali Bai Autonomous Prefecture, Yunnan Province from March to April, 2020, and identified and bred in laboratory. SD rats were infected with third-stage larvae of Angiostrongylus cantonensis that were isolated from commercially available Pomacea canaliculata snails in Dali Bai Autonomous Prefecture, and freshwater snails were infected with the first-stage larvae of A. cantonensis that were isolated from the feces of SD rats 39 days post-infection at room temperature. The developmental process and morphological characteristics of worms in hosts were observed, and the percentages of A. cantonensis infections in different species of freshwater snails were calculated. Then, SD rats were infected with the third-stage larvae of A. cantonensis that were isolated from A. cantonensis-infected freshwater snails, and the larval development and reproduction was observed. Results More than 3 000 freshwater snail samples were collected from farmlands, ditches and wetlands around Erhai Lake in Dali Bai Autonomous Prefecture, and Cipangopaludina chinensis, P. canaliculata, Parafossarulus striatulus, Oncomelania hupensis robertsoni, Galba pervia, Physa acuta, Radix swinhoei, Assiminea spp., Tricula spp. and Bellamya spp. were morphologically identified. A total of 105 commercially available P. canaliculata snails were tested for A. cantonensis infections, and 2 P. canaliculata snails were found to be infected with A. cantonensis, in which the third-stage larvae of A. cantonensis were isolated. Ten species of freshwater snails were artificially infected with the third-stage larvae of A. cantonensis, and all 10 species of freshwater snails were found to be infected with A. cantonensis, with the highest positive rate of A. cantonensis infections in Bellamya spp. (62.3%, 137/204), and the lowest in C. chinensis (35.5%, 11/31). After SD rats were infected with the third-stage larvae of A. cantonensis isolated from different species of freshwater snails, mature adult worms of A. cantonensis were yielded. Conclusions Multiple species of freshwater snails may serve as intermediate hosts of A. cantonensis under laboratory conditions in Dali Bai Autonomous Prefecture of Yunnan Province. Further investigations on natural infection of A. cantonensis in wild snails in Dali Bai Autonomous Prefecture seem justified.

In this paper， the name， origin， quality evaluation， producing area and processing methods of Lablab Semen Album in the famous classical formulas were researched by reviewing the ancient materia medica， medical books， prescription books and modern literature. The results showed that the name of Lablab Semen Album in the past dynasties was mostly derived from its shape and color， called Biandou and Baibiandou. The mainstream origin used in the past dynasties was Lablab purpureus， the medicinal parts were mainly white mature seeds， with the addition of the leaves in the Song dynasty and the flowers in the Ming dynasty. Since modern times， the authentic producing areas of Lablab Semen Album are Suzhou， Zhejiang and other places， and now mainly produced in Chuxiong and Xinping， Yunnan and Panzhihua， Sichuan. The traditional quality evaluation of Lablab Semen Album is evaluated as large， solid， full and white. The harvesting time of this herb is recorded from the eighth to the ninth lunar month in related literature， the pods are picked when the seeds are ripe， and the seeds are dried in the sun. In ancient times， the processing of Lablab Semen Album mainly consisted of frying the seeds with skin and then pulverizing for use， or soaking and peeling seeds for raw use. Based on the conclusion of the textual research， it is recommended that the seeds or flowers of the white flowering plants of L. purpureus， a member of the leguminosae， should be used in the famous classical formulas， and the dried seeds or dried flowers of Lablab Semen Album can be used as medicine if the formula did not clearly indicate processing requirements.

ObjectiveThe contamination of foodborne pathogens in ready-to-eat fruits and vegetables in Shanghai was analyzed to provide a scientific basis for food safety， risk assessment and related supervision. MethodsFrom June to September 2021， a total of 143 batches of12 kinds of ready-to-eat fruits and vegetables such as lettuce， chicory， and cherry tomatoes were collected from farmers’ markets， supermarkets， and e-commerce platforms. The total number of bacterial colonies， Salmonella， Listeria monocytogenes， Staphylococcus aureus， Cronobacter spp. and Shiga toxin-producing Escherichia coli in the samples were tested according to National Food Contamination and Harmfulness Risk Monitoring Manual. ResultsAmong the 143 batches， foodborne pathogens were detected in 68 batches， with a total detection rate of 47.55% （68/143）. A total of 79 strains of foodborne pathogens were detected. The detection rate of Staphylococcus aureus was the highest （32.87%， 47/143）， followed by Cronobacter spp. （20.98%， 30/143）， Salmonella （0.70%， 1/143）， Listeria monocytogenes （0.70%， 1/143）， Shiga toxin-producing Escherichia coli （0.00%）. Furthermore， the detection rate was higher in different ready-to-eat fruits and vegetables： chicory （17.33%）， cucumber （17.14%）， cherry tomatoes （16.00%）， and honeydew melon （15.38%）， respectively. Meanwhile， the contamination rate of pathogens in ready-to-eat fruits and vegetables from farmers’ markets， supermarkets， and e-commerce platforms was relatively high. ConclusionReady-to-eat fruits and vegetables in Shanghai are contaminated by foodborne pathogens. The prevention and control of the contamination of post-harvest fruits and vegetables should be strengthened to reduce the risk of foodborne disease outbreaks.

Objective： ：To detect the gene mutation in cholangiocarcinoma patients using the next generation sequencing (NGS) technology, and to analyze its correlation to the prognosis of the patients. Methods: From June 2016 to June 2018, 40 patients diagnosed with cholangiocarcinoma received NGS examination to screen the possible mutations (single base mutation, structural variation, copy number variation and gene fusion, etc.). The disease control rates (DCR), progression-free survival (PFS) and overall survival (OS) of the patients, who received the first line therapy, were retrospectively reviewed to analyze the relationship between signaling pathway as well as its genetic variation and the prognosis of cholangiocarcinoma patients. Results: The median PFS of patients with and without TP53 mutation was 11.0 and 8.3 months, respectively (P=0.332), while OS was 14.3 and 32.9 months, respectively (P=0.041). The median PFS of patients with and without PI3K mutations was 8.3 and 11.0 months, respectively (P=0.285), while OS was 14.3 and 37.0 months, respectively (P=0.020). The median PFS of patients with and without mTOR pathway mutations was 6.3 and 10.3 months, respectively (P=0.020), while OS was 15.6 and 19.6 months, respectively (P=0.892). There was no significant effect of pathway-related gene mutations on patients’survival. Conclusion: The prognosis of cholangiocarcinoma patients with TP53 and PI3K pathway activation had obviously poor prognosis than those without. No significant difference was observed between the patients with and without mTOR pathway activation and IDH mutation.

Objective To explore the attempted suicide risk factors of socio-demographic and clinical charac-teristics in major depressive disorder patients with atypical features (e.g. increased appetite, weight gain and greater time spent sleeping). Methods This was a secondary analysis of the data from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and carried out in 13 major mental health centers in China. Totally 179 patients were diagnosed as atypical major depres-sive disorder patients in all 1172 major depressive disorder patients using Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-Ⅳ) by psychiatrists. Suicide attempters and nonattempters were grouped base on the interview results of suicidality module of the Mini International Neuro-psychiatric Interview (MINI). Multiple logistic regression were used to assess association between independent variables and attempted suicide in major depressive disorder patients with atypical features. Results The rater of attempted snicide was 23.5% (42/179) of atypical major depressive disorder patients reported prior or current attempted suicide. Compared to nonattempters, attempters had higher levels of suicidal ideation, postpartum depressive episodes, and the use of antipsychotic, mood stabilizers and benzodiazepines (P<0.05). Logistic regression analysis showed that number of admissions (OR=1.73, 95% CI: 1.093~2.740) and depressive episodes with suicidal ideation (OR=3.90, 95%CI: 1.506~10.092) were significantly associat-ed with attempted suicide in atypical unipolar depression patients (P<0.05). Conclusions High number of admissions and high levels of suicidal ideation may be considered as potential risk factors to identify atypical unipolar depression patients at risk for future suicidal behavior.
