This study aimed to identify Inulae Herba, Inulae Flos and their closely related species using the ITS2 bar-code, and secure the quality and clinical curative effect of these medicinal materials. DNA was extracted from Inula linariifolia, I. japonica, I. britanica, which are the original species of Inulae Herba and Inulae Flos, together with their closely related species. The ITS2 sequence was amplified by PCR and sequenced bidirectionally. Sequence assembly and generation of consensus sequence were conducted by the CodonCode Aligner. The genetic distances were comput-ed using MEGA 5.0 in accordance with the Kimura-2-parameter (K2P) model, and the phylogenetic tree constructed by the neighbor-joining (NJ) method. The results showed that the ITS2 sequences of the various species have stable variable sites. The intraspecific genetic distances among Inulae Herba and Inulae Flos were obviously lower than the interspecific genetic distance among the above two medicinal materials and its adulterants. The NJ tree based on ITS2 sequences can clearly differ from Inulae Herba, Inulae Flos and their closely related species. It is concluded that ITS2 sequence can be used as DNA barcode to identify Inulae Herba, Inulae Flos and their closely related species.

Foreign body ingestion refers to the object that can not be digested in the gastintestic tract and can not be discharged from the body in time.In children with foreign bodies ingestion, the clinical symptoms and signs are often lack of specificity, and the medical history is sometimes unclear.If the treatment is not timely, it will have a serious impact on the healthy growth of children, which can cause various complications, and even death.In this review, the epidemic characteristics, clinical symptoms, foreign body′s types, locations, examinations, treatment and prognosis were described.

Objective To protect the economic benefits of the hospital by improving the medical record quality,quality control ability,and standardising the filling of the medical insurance settlement list.Methods Re-quality control of previous malignant tumour cases,with the help of the intelligent health insurance case collaboration system,compare the changes in case entry and benchmark costs after the revision of errors,analyse the results caused by different errors,and summarise the correct experience.Results Erroneous disease diagnoses can lead to losses or suspected fraud in health insurance billing,affecting the economic operation of healthcare organisations.Conclusion The improvement of the quality of the medical insurance settlement list not only needs to improve the quality of case writing,coding level,but also needs to read the connotation of the policy through extensive study.

Objective: To analyze the association between different sleep behaviors and overweight and obesity of junior high school students in Yangzhou City, and to provide a basis for policies and interventions related to adolescent health management. Methods: A total of 1 589 students in grades 7-9 from two middle schools in Yangzhou City were selected using the cluster sampling method and were administered with sleep time, bedtime, social jetlag difference, and sleep habits. Results: Totally 64.38% were sleep deprived during the school days, 86.78% went to bed too late, 46.51% had a social jetlag of ≥1 h, and 37.44% took a nap every day(Incluldes holidays and school days). Social jetlag length was statistically different between grades( F =6.97, P < 0.01 ). Girls[(0.95±0.65)h] shown significantly higher social jetlag than the boys[(0.76±0.59)h]( t=6.19, P <0.01). Later bedtime on weekends, later wake up time on weekends and poor sleep behavior were risk factors for overweight and obesity in junior high school students( OR=1.20, 1.14, 1.04, P <0.05). Conclusion Junior high school students had less sleep and later bedtimes with the increase of grade, and weekend bedtimes,wake up times and poor sleep behavior were independently associated with the risk of overweight and obesity in junior high school students. Parents and schools should be instructed to pay attention to their sleep health and carry out adolescent sleep health guidance.

PURPOSE: Intestinal dysfunction is one of the most common complications in patients after abdominal surgery. Daikenchuto (DKT), a traditional herbal medicine, is recently employed to improve postoperative intestinal dysfunction. The aim of this meta-analysis was to assess the efficacy of DKT in improving intestinal dysfunction after abdominal surgery. METHODS: PubMed, Embase, and the Cochrane library were systematically searched to identify randomized controlled trails (RCTs) in adult patients undergoing abdominal surgery, who were randomly distributed to administrate DKT and placebo. The primary outcomes included the time to first postoperative flatus or bowel movement. We used random-effects models to calculate summary mean differences (MDs) with 95% confidence intervals (CIs). RESULTS: Nine RCTs totaling 1,212 patients (618 in DKT, 594 in control group) were included in our study. Compared with control group, DKT can effectively improve postoperative intestinal dysfunction by shortening the time to first postoperative flatus (MD, −0.41; 95% confidence interval [CI], −0.66 to −0.16; P = 0.001) with significant heterogeneity (I2 = 71%, P = 0.004), and bowel movement (MD, −0.65; 95% CI, −0.97 to −0.32; P < 0.001) without significant heterogeneity (I2 = 40%, P = 0.14). Sensitivity analyses by indication of surgery and type of surgery yielded similar results. CONCLUSION: These data provide limited evidence that DKT shows efficacy on improving intestinal dysfunction after abdominal surgery. However, the results should be interpreted cautiously, due to the heterogeneity of the studies included. Thus, the efficacy of DKT on improving postoperative intestinal dysfunction warrants further investigation.

Objective The chemical composition and blood components of Tianmaxingnao capsules were discovered and examined using UPLC-Q/TOF-MS,and the possible pharmacological substance basis was preliminarily elucidated.Methods An UPLC-Q/TOF-MS method was developed in this study to determine the chemical composition of Tianma Xingnao capsules.After administration of Tianmaxingnao capsules,gather and examine rat plasma samples to investigate the exposed components of Tianmaxingnao capsules in rats.Results A total of 195 chemical components were identified in Tianmaxingnao capsules,including phenols,triterpenoid saponins,phenylethanol glycosides,cyclic ether terpenes,lipids,and phenylpropanoids.These components include those that are typical of Gastrodia elata Bl,Pheretima,Cistanche deserticola Ma,Rehmannia glutinosa,Polygala hybrida DC,and Acorus tatarinowii.Rat plasma samples were used to identify 37 prototype components and 3 metabolites of Tianmaxingnao capsules after they were administered.Conclusion This approach is easy to use,effective,sensitive,and precise.It may be used to investigate Tianmaxingnao capsules and the components that reach the bloodstream in detail,as well as to provide a first understanding of the pharmacological basis of the capsules.This study serves as a foundation for clarifying the pharmacological basis of Tianmaxingnao capsules and holds some reference value in exposing the pharmacological mechanism of the product.
