Huangqitang comes from the Taiping Huimin Hejiju Fang of the Song dynasty. It consists of four medicinal materials: Astragalus membranaceus var. mongholicus, Citrμs reticμlata， Cannabis sativa， and Apis cerana. It is a classic prescription for treating constipation in the elderly. This study systematically collated the literature records about Huangqitang in ancient Chinese medicine books and combined it with the current status of modern clinical applications to conduct in-depth analysis and research on the origin，composition， dosage, processing, preparation and administration, drug base, main symptoms， and other key information of the formula, so as to provide a strong reference for the development and clinical application of the classic Huangqitang compound preparation. Through systematic combing and textual research on the previous literature of Huangqitang， it can be seen that the formula of Huangqitang was first recorded in the Taiping Huimin Hejiju Fang， and the medical books of the past dynasties mostly adopted this formula. In terms of drug base， the dried roots of the leguminous plant Astragalus membranaceus var. mongholicus are used， and for tangerine， the dried outer peel of the Rutaceae plant Citrus reticμlata and its cultivated varieties are used. The Moraceae plant Cannabis sativa with the peel removed is selected, and the Apis cerana is selected from the honey brewed by Apis cerana， an insect of the Apidae family. In terms of dosage， although the dosage of some drugs changed during the Ming and Qing dynasties, the dosage records basically followed the original prescriptions from the Song dynasty. In terms of processing, preparation, and usage， although the drug processing， preparation， and usage of Huangqitang in the medical books of the past dynasties have changed slightly， they are basically the same as the original prescription of the Song dynasty. In terms of main symptoms, Huangqitang is designed to treat constipation in the elderly. From the Song dynasty to the Qing dynasty， it was mostly used to treat constipation， secret congestion, asthenia， etc. in the elderly. In modern times， it is clinically used to treat constipation due to Qi deficiency， functional constipation， irritable bowel syndrome， and other diseases in the elderly. No adverse reactions have been found yet. In the subsequent research and development， it is necessary to carry out mass spectrometry analysis of Huangqitang， in-depth exploration of its prescription efficacy and mechanism of action， and other multi-omics scientific research. At the same time， it is important to establish quality control standards to provide a reliable scientific basis for the research and development, clinical treatment， and drug supervision of Huangqitang compound preparations.

Objective: To explore the moderating role of estradiol in the relationship between parenting styles and preschool children's behavioral problems, so as to provide a theoretical basis for improving the development of human s emotional health development in early life stage. Methods: During September to November in 2022, 354 children aged 3-6 years and their parents from two kindergartens in Bengbu City were chosen by using stratified cluster sampling method for the questionnaire survey. The Parenting Style Scale and the Child Behavior Checklist (CBCL) were used to collect information on parenting style and child behavioral problems. Salivary estradiol of children was collected and tested. Independent samples t test was applied to compare the scores of the scale for parental up bringing and children s behavioral problems, and Pearson correlation analysis was conducted to explore the relationship among parental upbringing, estradiol and children s behavioral problems. Results: Parents doting, laissez faire, autocratic, and inconsistent parenting styles were positive associated with child behavior problems( r =0.14-0.70); fathers democratic parenting style was negatively associated with child behavior problems( r =-0.14，-0.22，-0.21，-0.17，-0.27，-0.20); mothers democratic parenting styles was negatively correlated with scores on all five dimensions of child behavior problems except the withdrawal dimension ( r =-0.14，-0.12，-0.13，-0.21，-0.12)( P <0.05). Estradiol levels had significant moderating effects on maternal doting parenting style and children s withdrawal ( β =0.68) as well as social problems ( β =-1.00), also moderating laissez faire parenting styles and children s withdrawal problems ( β =0.75)( P <0.05). For children with low levels of estradiol, withdrawal problem scores were negatively associated with mother s doting parenting style and positively associated with laissez faire parenting style, and socialization problem scores were associated with mother s doting parenting style; for children with high levels of estradiol, withdrawal problem scores were positively associated with mother s doting parenting style, and socialization problem scores were associated with mother s doting parenting style ( t=2.84, 6.24, 3.16 , 2.37, 4.49, P <0.05). Conclusions Parenting styles are strongly associated with child behavioral problems; estradiol levels play a moderating role in mothers doting, laissez faire parenting styles and children s withdrawal problems and social problems.Parents should adopt more positive parenting styles and focus on the role of estradiol levels in maternal education to reduce the occurrence of behavioral problems in children.

Asian ginseng mostly appeared in herbal medical books in the late Qing Dynasty and the early Republic of China.In modern literature,it is believed that this drug is alias of vigorously cultivated ginseng,Talinum paniculatum(Jacq.)Gaertn.,Pananis Japonici Rhizoma,Arctii Fructus and other drugs,and the origin is confused.This article made a textual research on the name,origin,producing areas,processing,property and taste,and efficacy.It is concluded that the Asian ginseng was earlier included in the Ben Cao Gang Mu Shi Yi in the Qing Dynasty,and was named Asian ginseng because it was produced in Japan.The original plant is Panax ginseng C.A.Meyer,which is a kind of Araliaceae plant.It takes Yunzhou,Huijin and Xinzhou of Japan as the true land,and is also cultivated in Northeast China.Asian ginseng medicinal materials are made by processing techniques such as net whiskers,boiling,cooling,and exposure to dryness.They are warm in property,sweet and slightly bitter in taste.They are good at tonifying qi and generating fluid,and can treat all deficiency syndromes of fluid and qi.In the Qing Dynasty,they were often used as Ginseng Radix et Rhizoma.The identification of false was also attached for distinguishing.

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.

Objective:To explore the clinical and endoscopic features of patients with autoimmune gastritis (AIG) and to improve the accuracy of clinical diagnosis of AIG.Methods:From January 3, 2020 to November 25, 2021, the general information (gender, age), laboratory examination indicators and endoscopic findings of 179 AIG patients diagnosed at the Second Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The laboratory examination indicators included hemoglobin, gastrin-17, pepsinogen (PG), anemia combination indicators (ferritin, vitamin B 12), thyroid function indicators (thyroid-stimulating hormone, thyroglobulin antibody and thyroid peroxidase antibody), Helicobacter pylori, and anti-parietal cell antibody and anti-intrinsic factor antibody. Descriptive methods were used for statistical analysis. Results:Among the 179 AIG patients, there were 42 males (23.5%) and 137 females (76.5%), with an average age of (55.23±12.04) years old. The gastrin-17 level of AIG patients was 195.31 ng/L (143.64 ng/L, 273.61 ng/L), PG Ⅰ level and PG Ⅰ/PG Ⅱ ratio were 12.40 μg/L (7.65 μg/L, 19.40 μg/L) and 1.03 (0.66, 1.52), respectively. There were 15.3% (18/118) of the AIG patients with iron deficiency anemia, and 16.1% (19/118) with megaloblastic anemia. The positive rate of anti-parietal cell antibody was 71.8% (51/71), and the positive rate of anti-intrinsic factor antibody was 25.4% (18/71). The serum thyroid-stimulating hormone level increased in 27.3% (15/55) of the patients, and the positive rates of thyroglobulin antibody and thyroid peroxidase antibody were 31.6% (12/38) and 47.4% (18/38), respectively. The positive rate of Helicobacter pylori was 29.7% (38/128). The endoscopic appearance of AIG indicated reverse atrophy, characterized by obvious atrophy in gastric fundus and gastric body mucosa, however the atrophy of gastric antrum was not obvious. Under endoscopy yellow-white turbid mucus, which was difficult to be washed, was found in 67.0% (120/179) of the patients, and under endoscopy the residual gastric fundus glands could be seen in 19.6% (35/179) of the patients. Among 179 AIG patients, 7 cases (3.9%) of neuroendocrine tumor (NET), 7 cases (3.9%) of early gastric adenocarcinoma (including 1 case of poorly differentiated adenocarcinoma), 1 case (0.6%) of adenoma, and 14 cases (7.8%) of hyperplastic polyps were found. Except for the case of poorly differentiated adenocarcinoma undergoing surgery, the others were treated with endoscopic resection. Conclusions:When unexplained iron deficiency anemia, megaloblastic anemia, or reverse atrophy is found, AIG should be considered. AIG patients are at high risk for gastric cancer and NET, and should be closely followed up, and active treatment should be given before anemia and neurological symptoms appear.

Objective: To understand physical activity status of children and adolescents in Tujia inhabited areas, and to provide reference for the intervention model of physical activity of children and adolescents in minority areas. Methods: A cluster sample of 2 466 Tujia pupils from two primary schools in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture of Hubei Province was selected to investigate physical activity status of Tujia pupils. The univariate χ 2 test was used to analyze the physical activity status of Tujia children and adolescents and its influencing factors. Results: The median duration of high intensity activity was 49.9 minutes/day in the last week, and 47.93% of participants met the physical activity standard( χ 2=80.47, P <0.01), the median duration of sitting was 396.1 minutes/day in the last week, and the qualified rate of screen time was 78.99%, and the differences of qualified rate between daystudents and residential students were of statistical differences( χ 2=35.12, P <0.01)). Conclusion The children and adolescents in the Tujia community are lack of physical activity. Therefore, it is necessary to take effective intervention measures to pay attention to the children and adolescents physical activity.

Objective: To understand the prevalence of low vision among Tujia and Han children and adolescents in Tujia inhabited areas, and to provide reference for the prevention and control of myopia in children and adolescents in minority areas. Methods: A cluster sampling of Tujia and Han primary school students from two primary schools in Lichuan City, Enshi Tujia and Miao Autonomous Prefecture, Hubei Province (2 466 Tujia and 971 Han) were selected for visual acuity assessment. Univariate χ 2 test and multivariate Logistic analysis were used. Low vision and associated factors between Tujia and Han nationality were compared. Results: The overall detection rate of low vision among children and adolescents in Tujia inhabited areas was 44.9%. There were differences in the degree of low vision in the left and right eyes of individuals, and the detection rate of low vision varied significantly by ethnic, gender and grade ( χ 2=22.10, 18.43, 19.06, 17.97 for the left eye, 17.52, 20.44, 21.49, 18.61 for the right eye, P < 0.05). There were many factors affecting low vision among children and adolescents in Tujia inhabited areas, overweight and obesity were negatively associated with low vision ( OR=1.81, 1.70, 95%CI=1.76-1.92, 1.66-1.82, P <0.01). Conclusion Low vision is highly prevalent in Tujia children and adolescents. Effective intervention measures should be taken to treat and prevent myopia in children and adolescents.

Objective:To explore the effects of Nd 2O 3 exposure to rare earth particles on the secretion of sex hormones, cytochrome P450 family member 11A1 (CYP11A1) , spermatogenesis markers promyelocytic leukemia zinc finger protein (PLZF) and retinoic acid stimulating gene 8 (STRA8) protein in C57 BL/6J male mice. Methods:In March 2021, Forty-eight male C57 BL/6J mice aged 6-8 weeks divided into control group and Nd 2O 3 exposure low, medium and high dose groups (exposing doses of 62.5, 125.0, 250.0 mg/ml Nd 2O 3) , 12 per group. The mice in the Nd 2O 3 groups were perfused with different doses of Nd 2O 3 suspension by a one-time non-exposing tracheal instillation method, and the control group was perfused with an equal volume of normal saline, with a volume of 0.1 ml, to establish a mouse reproductive function injury model. After 28 days of exposure, the mice's body weight, testes and epididymis were weighed, and the organ coefficients were calculated; the two epididymis were taken to make a sperm suspension to determine the sperm count, survival rate, and deformity rate; inductively coupled plasma mass spectrometry (ICP-MS) method was used to detect the content of Nd in mouse testis tissue; HE staining was used to detect testicular tissue pathological changes and quantitative analysis; enzyme-linked immunosorbent assay (ELISA) method was used to detect serum luteinizing hormone (LH) and follicle stimulating hormone (FSH) and testosterone (T) content; western blot was used to detect the protein levels of CYP11A1, PLZF and STRA8 in testicular tissues. Results:Compared with the control group, with the increase of the exposure dose, the Nd content in the testis of the mice showed an increasing trend, the sperm survival rate and LH showed a decreasing trend, and the sperm deformity rate showed an increasing trend ( P<0.05) ; Pathological showed that the number of sperm in the seminiferous tubules of the testicular tissue in the Nd 2O 3 medium and high dose groups was significantly reduced, and the germinal epithelial disintegration, intraepithelial vacuolization, and exfoliation of spermatogenic cells and supporting cells occurred; The height of germinal epithelium was significantly reduced, and the percentage of damaged seminiferous tubules showed an increasing trend ( P<0.05) ; FSH and T levels in serum in the middle and high dose groups of Nd 2O 3, and CYP11A1, PLZF and STRA8 proteins in testicular tissues showed a downward trend with increasing dose ( P<0.05) . Conclusion:The rare earth particulate Nd 2O 3 may interfere with the expression of CYP11A1, PLZF and STRA8 protein, thereby causing the disorder of sex hormone secretion in the body, the maintenance of spermatogonia and the obstruction of the process of meiosis, causing reproductive function damage.

Objective:To explore the effects of endoscopic reprocessing on disinfection and its influential factors under the coronavirus disease 2019 (COVID-19) pandemic.Methods:A total of 450 endoscopes cleaned and disinfected according to Technical Specifications for Cleaning and Disinfection of Endoscopes from November 2019 to January 2020, and 450 endoscopes cleaned and disinfected according to The recommended procedure for cleaning and disinfection of gastrointestinal endoscopes during COVID-19 epidemic by Chinese Society of Digestive Endoscopology from February to April 2020 in the Second Affiliated Hospital of Chongqing Medical University were enrolled in the control group and observation group respectively by random number method. Both the control group and the observation group contained 200 gastroscopes, 200 enteroscopes and 50 ultrasound endoscopes. ATP fluorescence detection method and pour plate technique were used to evaluate the disinfection effect of endoscopes. Single factor analysis and multiple logistic regression were used to analyze the risk factors for unqualified sterilization after endoscopic reprocessing. Results:The disinfection pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were not significantly different compared with those of the control group ( P>0.05). The sterilization pass rates and ATP test pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were significantly higher than those in the control group (all P<0.05). Multivariate logistic regression analysis showed that non-strict implementation of endoscopic reprocessing ( OR=7.96, 95% CI: 4.55-22.84, P<0.001), non-standard operation ( OR=2.26, 95% CI: 1.24-5.63, P<0.001), insufficient concentration of disinfectant ( OR=5.43, 95% CI: 2.52-9.02, P<0.001), insufficient concentration ratio of multi-enzyme solution ( OR=4.38, 95% CI: 1.95-8.61, P<0.001), non-timely cleaning ( OR=2.86, 95% CI: 1.33-6.42, P<0.001), incomplete cleaning ( OR=3.75, 95% CI: 1.61-7.49, P<0.001) and improper endoscopic preservation ( OR=2.12, 95% CI: 1.36-4.12, P<0.001) were independent risk factors for unqualified sterilization after endoscopic reprocessing. Conclusion:In COVID-19 pandemic, endoscope reprocessing can significantly improve the disinfection effect of endoscopes, worthy of further clinical promotion. The failure to strictly implement the reprocessing procedure is an important factor that may lead to unqualified sterilization.
