Scoping review of research on mobile app-based weight management in patients with breast cancer / 中华健康管理学杂志

Objective:To conduct a scoping review of mobile app-based weight management studies in patients with breast cancer.Methods:The studies related to weight management in patients with breast cancer based on mobile apps in nine Chinese and English databases, including PubMed, Embase, Cochrane, EBSCOhost, Scopus, Sinomed, VIP database, Wanfang Database and China National Knowledge Infrastructure (CNKI), were systematically searched with the terms of “breast cancer” “weight management” “mobile health” and “weight”. The search period was from the establishment of the databases to July 29, 2022. The literature was screened, and data were extracted and summarized based on the Omaha system.Results:A total of 7 literatures were included, all were in English. The mobile apps included in the studies varied with sample sizes, ranging from 10 to 356 cases. Six of the studies involved breast cancer patients who had completed surgery or chemoradiotherapy, and none of the studies involved breast cancer patients undergoing chemotherapy. Forms of intervention included exercise or diet alone and a combination of both exercise and diet, and most studies had shown good intervention effects. According to the Omaha intervention system, the most commonly extracted intervention component was self-management advice, which was offered to patients in six studies, and none of the intervention studies included intervention components related to case management.Conclusions:An intervention for weight management based on mobile apps in breast cancer patients has a good effect and is feasible. However, there is a limited number of related studies, and there is a lack of interventional research specifically targeting patients during chemotherapy, which still needs to be actively carried out.

Herbal Textual Research on Tsaoko Fructus in Famous Classical Formulas / 中国实验方剂学杂志

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.

Herbal Textual Research on Lablab Semen Album in Famous Classical Formulas / 中国实验方剂学杂志

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.

Research progress of brain imaging in cognitive behavioral therapy for depression / 中华行为医学与脑科学杂志

The prevalence and recurrence rate of depressive disorder are high, while the recognition and cure rate are low. Early intervention can improve the quality of life of patients with depression. In clinical practice, it has been found that psychological treatments can effectively improve the symptoms and prognosis of depression.Cognitive behavior therapy(CBT) has been widely used in the treatment of depression, however, its mechanisms are still unclear. In this paper, the neuroimaging studies of patients with depression before and after CBT were summarized, and the structural or functional changes of different brain regions in patients with depression before and after CBT were described. The findings suggest that CBT improved depressive symptoms by increasing gray matter volume, activation level, and functional connectivity strength in the dorsolateral prefrontal cortex, reducing activation levels in the amygdala and parahippocampal gyrus, and restoring abnormal brain network activity or functional connectivity. Larger gray matter volume in anterior cingulate gyrus and higher activation levels in hippocampus and amygdala before treatment can effectively predict the effect of CBT in depressed patients. In the future, machine learning could be combined with brain imaging data to more accurately predict the effectiveness of CBT in treating depression.

Research Progress of Etiology, Screening and Early Diagnosis of Esophageal Cancer in China / 肿瘤防治研究

Esophageal cancer (EC) is one of the most fatal cancers worldwide. According to GLOBOCAN 2020, it was estimated that there were 600, 000 new EC cases and 540 000 EC deaths, while nearly half of all newly diagnosed cases of EC and associated deaths worldwide occurred in China. The annual incidence and mortality of EC have been reduced in the last 20 years in China. However, the early symptoms and signs of EC are not easily distinguished and the disease tends to be within the middle and late stage of pathogenesis when identified, leading to its low 5-year survival rate. Therefore, it could help effectively reduce the burden of EC by clarifying its etiology and risk factors, as well as taking preventive and early diagnosis measures. This article reviews the epidemiology, etiology, screening and early diagnosis of EC in China, to provide systematic references for EC prevention and control.

Carnivorous planktonic Difflugia (Protista, Amoebina Testacea) and their predators.

Four planktonic species of Difflugia co-occurring in a south Chinese reservoir were found to be carnivorous, but the diet was widest in the largest species (D. tuberspinifera) and narrowest in the smallest (D. hydrostatica). It included rotifers, ciliates, dinoflagellates, floating eggs, and small particles associated with organic debris. Scavenging and cannibalism were also observed. Species with a collared test (D. biwae, D. mulanensis) showed a form of suction-feeding, while species with teeth on the pseudostome used these, together with their pseudopods, as "inverted crown corks", providing leverage for opening the lorica of their (rotifer) prey. Predators of Difflugia included cyclopoid copepods. In addition, the rotifers Asplanchna priodonta, Ploesoma hudsoni and, occasionally, big ciliates (Stentor sp.) all ingested their prey as a whole.
