Résumé

Objective: To explore the relationship between nutrient-related dietary pattern and mild cognitive impairment (MCI) in middle-aged and elderly people. Methods: A total of 6 444 middle-aged and elderly people aged ≥55 years were selected in 2018 China Health and Nutrition Survey. MCI was evaluated by Mini-Mental State Examination, and the intakes of various foods were obtained by consecutive 3-day 24-hour dietary survey and weighing method. The intakes of various nutrients and total dietary energy were calculated based on the food composition table. Demographic and social information, lifestyle and health status of the respondents were obtained through questionnaire survey and physical measurements. In this study, vitamin C, vitamin E, zinc, iron, copper and selenium were selected as dependent variables. Nutrient-related dietary patterns were extracted by reduced rank regression method, and the relationship between dietary patterns and MCI was analyzed by multivariate logistic regression model. Results: Six dietary patterns were extracted in this study, and dietary pattern 1 with the highest explanatory degree was selected for subsequent analysis. Dietary pattern 1 was characterized by higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products and plant oil. Multivariate logistic regression analysis showed that the risk of MCI was lower in Q4 dietary score group than in Q1 dietary score group (OR=0.69, 95%CI: 0.49-0.98) in the 55-64 age group. In people with sleep duration of 8 hours per day, the risk of MCI was reduced in Q2, Q3 and Q4 dietary score groups compared with the Q1 dietary score group, with OR values of 0.68 (95%CI: 0.51-0.92), 0.67 (95%CI: 0.49-0.92) and 0.65 (95%CI: 0.45-0.92), respectively. Interaction analysis showed that the risk for MCI increased in those aged 65-74 years and ≥75 years compared with those aged 55-64 years in Q1 dietary score group. However, the risk for MCI decreased in both age groups as dietary pattern scores increased. Compared with those with sleep duration less or more than 8 hours per day in Q1 dietary score group, those with sleep duration of 8 hours per day in Q2 and Q3 dietary score groups had a reduced risk for MCI. Conclusion: Dietary patterns with higher intakes of legume products, vegetables, fruits, nuts, pork, aquatic products, and plant oil are negatively associated with MCI in people aged 55-64 years and those who slept 8 hours per day, and may reduce the risk of MCI with aging.

Résumé

Objective: To analyze the drug resistance and genomic characteristics of a strain of serogroup O139 Vibrio cholerae producing cholera toxin isolated from the bloodstream of a person with bacteremia. Methods: The broth dilution method and automatic drug sensitivity analyzer were used to determine the antibiotic sensitivity of the strain. The complete genome sequence of the strain was obtained by using second-generation gene sequencing and nanopore sequencing. BLAST software was used for comparison and analysis with CARD, Resfinder, ISfinder, VFDB, and other databases. The drug-resistant genes, insertion sequences and virulence genes carried by the strain were identified. MEGA 5.1 software was used to construct a genetic phylogenetic tree based on the core genomic single nucleotide polymorphisms. Results: V. cholerae SH400, as the toxigenic strain, carried multiple virulence-related genes and four virulence islands. The strain was resistant to streptomycin, tetracycline and cotrimoxazole, carrying corresponding drug-resistant genes. The strain also carried IncA/C plasmid with the size of 172914 bp and contained 10 drug-resistant genes. Combined with the genomic evolutionary relationship, this study found that the drug-resistant genes and drug-resistant plasmids carried among strains showed certain aggregation. The traditional ST type of strain SH400 was ST69, and the cgMLST type was a new type highly similar to cgST-252. Conclusion: This strain of serogroup O139 V. cholerae carries the ctxAB gene, multiple drug-resistant genes and IncA/C plasmid, and there are multiple drug-resistant islands.

Résumé

Sintilimab is an anti-programmed cell death receptor-1 antibody. The phase III clinical trial ORIENT-12 confirmed the safety of sintilimab combined with pemetrexed/platinum in the treatment of advanced squamous non-small cell lung cancer. Skin reactions are the most commonly reported adverse events of immune checkpoint inhibitors and are rarely severe.We describe a case of toxic epidermal necrolysis related to sintilimab in an elderly oncologic patient. 3 weeks after immunotherapy, the patient developed an extensive rash and diffuse itching, rapidly evolving into macules, blisters, bullae and erosions. Causal evaluation was performed based on the algorithm of drug causality for epidermal necrolysis and national Food and Drug Administration qualitative analysis. The patient responded to high-dose glucocorticosteroid and supportive therapy, alongside with local wound care. If immune checkpoint inhibitors need to be extrapolated clinically, strictly following evidence-based research, promptly detecting and treating adverse reactions is crucial.

Résumé

This study aims to observe the effect and explore the mechanism of Qirong Tablets in the treatment of premature ovarian insufficiency(POI) in mice via the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/hypoxia inducible factor 1(HIF-1) signaling pathway. Sixty SPF female BALB/c mice were randomly divided into normal group, model group, positive control group, Qirong Tablets low-, medium-and high-dose group. The normal group was intraperitoneally injected with the same amount of normal saline, and the other groups were intraperitoneally injected with cyclophosphamide 120 mg·kg~(-1)·d~(-1) once to establish a POI animal model. After the model was successfully established, the low-, medium-and high-dose groups of Qirong Tablets were administered orally with 0.6, 1.2, 2.4 mg·kg~(-1)·d~(-1) respectively. The positive control group was given 0.22 mg·kg~(-1)·d~(-1) Clementine Tablets by intragastric administration, and the normal group and model group were given intragastric administration with the same amount of normal saline, and the treatment was 28 d as a course of treatment. After drug intervention, enzyme-linked immunosorbent assay(ELISA) was employed to measure the levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-mullerian hormone(AMH) in peripheral blood, and hematoxylin-eosin(HE) staining to observe the ovarian tissue. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) assay was used to detect the apoptosis of granulosa cells, and Western blot to determine the expression levels of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), caspase-3, PI3K, Akt, and HIF-1. Compared with the normal group, the modeling of POI caused loose or destroyed ovarian tissue with vacuolar structures, edema and fibrosis in the ovarian interstitium, disordered or loose arrangement of granulosa cells, and reduced normal follicles. Compared with the model group, drug interventions restored the ovarian tissue and follicles at all the development stages and reduced atretic follicles. Compared with the normal group, the modeling of POI lowered the serum level of E_2 and AMH(P<0.01), and elevated the level of FSH and LH(P<0.01). Compared with the model group, high-dose Qirong Tablets elevated the levels of E_2 and AMH(P<0.05), and lowered the levels of FSH and LH(P<0.05). Compared with the normal group, the modeling of POI up-regulated the protein levels of PI3K, Akt, HIF-1, Bax, and caspase-3 and down-regulated the protein level of Bcl-2 in the ovarian tissue(P<0.01). Compared with the model group, low-, medium-, and high-dose Qirong Tablets down-regulated the protein levels of PI3K, Akt, HIF-1, Bax, and caspase-3 proteins and up-regulated the protein level of Bcl-2 in the ovarian tissue(P<0.05). In conclusion, Qirong Tablets can up-regulate the expression Bcl-2, down-regulate the expression of Bax and caspase-3 in POI mice. Qirong Tablets may inhibit the apoptosis of follicular granulosa cells in mice, thereby delaying ovarian aging, improving reproductive axis function, and strengthening ovarian reserve capacity, which may be associated with the inhibition of PI3K/Akt/HIF-1 pathway.

Résumé

Objective: To evaluate the clinical value of the MeltPro MTB assays in the diagnosis of drug-resistant tuberculosis. Methods: A cross-sectional study design was used to retrospectively collect all 4 551 patients with confirmed tuberculosis between January 2018 and December 2019 at Beijing Chest Hospital, Capital Medical University. Phenotypic drug sensitivity test and GeneXpert MTB/RIF (hereafter referred to as "Xpert") assay were used as gold standards to analyze the accuracy of the probe melting curve method. The clinical value of this technique was also evaluated as a complementary method to conventional assays of drug resistance to increase the detective rate of drug-resistant tuberculosis. Results: By taking the phenotypic drug susceptibility test as the gold standard, the sensitivity of the MeltPro MTB assays to detect resistance to rifampicin, isoniazid, ethambutol and fluoroquinolone was 14/15, 95.7%(22/23), 2/4 and 8/9,respectively; and the specificity was 92.0%(115/125), 93.2%(109/117), 90.4%(123/136) and 93.9%(123/131),respectively; the overall concordance rate was 92.1%(95%CI:89.6%-94.1%),and the Kappa value of the consistency test was 0.63(95%CI:0.55-0.72).By taking the Xpert test results as the reference, the sensitivity of this technology to the detection of rifampicin resistance was 93.6%(44/47), the specificity was100%(310/310), the concordance rate was 99.2%(95%CI:97.6%-99.7%), and the Kappa value of the consistency test was 0.96(95%CI:0.93-0.99). The MeltPro MTB assays had been used in 4 551 confirmed patients; the proportion of patients who obtained effective drug resistance results increased from 83.3% to 87.8%(P<0.01); and detection rate of rifampicin, isoniazid, ethambutol, fluoroquinolone resistance, multidrug and pre-extensive drug resistance cases were increased by 3.2%, 14.7%, 22.2%, 13.7%, 11.2% and 12.5%, respectively. Conclusion: The MeltPro MTB assays show satisfactory accuracy in the diagnosis of drug-resistant tuberculosis. This molecular pathological test is an effective complementary method in improving test positivity of drug-resistant tuberculosis.

Résumé

The infiltration of immune cells into the hepatocellular carcinoma microenvironment is the main reason why hepatocellular carcinoma patients are prone to carcinoma recurrence and the disease are incurable. Notably, the infiltration of Treg cells is the main trigger. Dahuang Zhechong pill (DHZCP) is a traditional Chinese herbal compound successful in the treatment of hepatitis and hepatocellular carcinoma. DHZCP can heal and nourish while slowing the onset of the disease, thereby strengthening the body's immune function. It can localize tumors and ultimately achieve the goal of eliminating tumors. In this study, an orthotopic liver cancer model of mice was used to explore the mechanism of DHZCP enhancing anti-tumor immunity, which showed more Th1 cells in the peripheral blood and spleen after DHZCP treatment, while more IFN-γ was secreted to activate CD8+ T cells and Treg cell production was inhibited, thereby suppressing the growth of HCC. Finally, we also analyzed the potential components of DHZCP from the perspective of modern targets using network pharmacology methods and experimental results.

Résumé

Objective:To investigate the clinical characteristics of acute ischemic stroke with anterior circulation large vessel occlusion caused by cardioembolism (CE) and large artery atherosclerosis (LAA) and the efficacy of endovascular treatment.Methods:Patients with acute ischemic stroke caused by large vessel occlusion in anterior circulation and received endovascular treatment in the Stroke Center of the 971 st Hospital of the PLA Navy from April 2014 to April 2021 were retrospectively enrolled. The etiological classification of stroke was CE or LAA. According to the modified Rankin Scale score at 90 d after onset, the patients were divided into good outcome group (0-2) and poor outcome group (>2). The demographic and clinical data between the groups were compared. Multivariate logistic regression analysis was used to determine the independent influencing factors of clinical outcome. Results:A total of 106 patients were enrollded. Their age was 61.39±13.73 years and 70 (66.0%) were males. Seventy-four patients (69.8%) were in the CE group and 32 (30.2%) were in the LAA group. Sixty-six patients (62.3%) had good outcomes. Univariate analysis showed that there were significant differences in gender, age, smoking, systolic blood pressure, diastolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) score, time from onset to femoral artery puncture, time from puncture to vascular recanalization, and the number of retrieval attempts between the CE group and the LAA group (all P<0.05), and there were no significant differences in the incidences of poor outcome, hemorrhagic transformation, and symptomatic intracranial hemorrhage. There were significant differences in systolic blood pressure, diastolic blood pressure, baseline NIHSS score, time from onset to femoral artery puncture, and blood perfusion grade after treatment between the good outcome group and the poor outcome group (all P<0.05). Multivariable logistic regression analysis showed that higher systolic blood pressure (odds ratio [ OR] 1.046, 95% confidence interval [ CI] 1.014-1.078; P=0.004), higher baseline NIHSS score ( OR 1.117, 95% CI 1.037-1.203; P=0.003), longer time from onset to femoral artery puncture ( OR 1.008, 95% CI 1.001-1.015; P=0.019) and poor blood perfusion after treatment ( OR 8.042, 95% CI 1.532-42.215; P=0.014) were significantly and independently associated with the poor outcomes. Conclusions:Compared with LAA, CE do not increase the risks of hemorrhagic transformation and symptomatic intracranial hemorrhage. The safety and efficacy of the two are similar.

Résumé

Polycystic ovary syndrome (PCOS) is a common disease caused by complex endocrine and metabolic abnormalities in women of childbearing age. Metformin is the most widely used oral hypoglycemic drug in clinic. In recent years, metformin has been used in the treatment of PCOS, but its mechanism is not clear. In this study, we aimed to investigate the effect of metformin on PCOS and its mechanism through PCOS mouse model. Female C57BL/6J mice aged 4-5 weeks were intragastrically given letrozole (1 mg/kg daily) combined with a high-fat diet (HFD) for 21 days to establish the PCOS model. After modeling, metformin (200 mg/kg daily) was intragastrically administered. One month later, the body weight and oral glucose tolerance test (OGTT) were measured. Hematoxylin eosin (H&E) staining was used to detect the pathological changes of ovary. The serum levels of anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2 and testosterone (T) were measured by ELISA. The expression of DDX4/MVH was detected by immunohistochemistry. DDX4/MVH and PCNA were co-labeled by immunofluorescence. The protein levels of DDX4/MVH, PCNA, cyclin D2, AMPK and mTOR were detected by Western blot. The results showed that after metformin treatment, the body weights of PCOS mice were gradually returned to normal, glucose tolerance was significantly improved, serum E2 levels were increased, while AMH, LH, T levels and LH/FSH ratio were decreased. Ovarian polycystic lesions were reduced with reduced atresia follicles. Furthermore, the number of proliferative female germline stem cells (FGSCs) and levels of proliferation related proteins (PCNA, cyclin D2) were significantly increased, and the p-mTOR and p-AMPK levels were markedly up-regulated. These results suggest that metformin treatment not only improves hyperandrogenemia, glucose intolerance and polycystic ovarian lesions in PCOS, but also activates the function of FGSCs. The underlying mechanism may be related to the phosphorylation of AMPK and mTOR. These findings provide new evidence to use metformin in the treatment of PCOS and follicular development disorder.

Résumé

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at Shenmen (HT 7) and Sanyinjiao (SP 6) on anxiety and depression in patients with insomnia, and to explore the mechanism of its compatibility effect.@*METHODS@#Ninety patients of insomnia were randomly divided into a combination group, a Shenmen group and a Sanyinjiao group, 30 cases in each group. In addition, 37 cases with anxiety (12 cases in the combination group, 13 cases in the Shenmen group and 12 cases in the Sanyinjiao group) and 42 cases with depression (14 cases in the combination group, 14 cases in the Shenmen group and 14 cases in the Sanyinjiao group) were identified. The patients in the combination group, Shenmen group and Sanyinjiao group were treated with EA (dilatational wave, frequency of 5 Hz/25 Hz) at Shenmen (HT 7)-Sanyinjiao (SP 6), Shenmen (HT 7) and Sanyinjiao (SP 6), respectively, 30 min each treatment, once a day. The consecutive 5 days of treatments were taken as a course of treatment, and 2 courses of treatment were given. The insomnia severity index (ISI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores were evaluated before and after treatment, and the serum contents of dopamine (DA) and norepinephrine (NE) were measured.@*RESULTS@#Compared before treatment, the ISI, SAS and SDS scores in the three groups were all decreased after treatment (P<0.05), and the ISI score in the combination group was lower than that in the Shenmen group (P<0.05). Among the patients with anxiety, compared before treatment, the ISI, SAS scores and serum contents of DA were all decreased after treatment in the three groups (P<0.05), and the serum contents of NE in the combination group and Shenmen group were decreased after treatment (P<0.05); the SAS score and serum contents of NE in the combination group and Shenmen group as well as the ISI score in the combination group were lower than those in the Sanyinjiao group (P<0.05). Among the patients with depression, compared before treatment, the ISI, SDS scores and serum contents of DA were all decreased after treatment in the three groups (P<0.05), and the serum contents of NE in the combination group and Shenmen group were decreased after treatment (P<0.05); the ISI, SDS scores and serum contents of NE in the combination group as well as SDS score in the Shenmen group were lower than those in the Sanyinjiao group (P<0.05).@*CONCLUSION@#EA at Shenmen (HT 7) and Sanyinjiao (SP 6) has advantages over EA at Sanyinjiao (SP 6) on improving insomnia, anxiety and depression. Shenmen (HT 7) plays a major role in improving anxiety and depression. Shenmen (HT 7) and Sanyinjiao (SP 6) may play a compatibility effect of regulating consciousness and sleeping by reducing the level of serum NE.

Résumé

By systematically sorting out the ancient medical books and modern clinical literature of Yiguanjian, the historical evolution of this formula, including its source, composition, origin, processing, dosage, preparation and usage, functions and indications, evolution of prescription meaning, is textual so as to clarify the historical evolution and clinical application of Yiguanjian. On the basis of fully considering the actual demand of development of famous classical formula preparation and the usage habit of modern clinical practice, the feasible development suggestions were put forward. Yiguanjian is composed of six herbs, which is derived from Yifang Jiedu (《医方絜度》) . It is an ancient book of traditional Chinese medicine edited by QIAN Min-jie in Qing dynasty. The original medicinal plants and medicinal parts of the formula were basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. The raw products should be selected for decoction pieces and processed according to the methods recorded in the 2020 edition of Chinese Pharmacopoeia. The reference dose of the medicine in this formula is set out in Yifang Jiedu. According to dosage of one Qian(钱)=3.73 g, the dosages of Glehniae Radix, Ophiopogonis Radix and Angelicae Sinensis Radix were 5.60 g, the dosages of Lycii Fructus and Rehmanniae Radix were 11.19 g, the dosage of Toosendan Fructus was 7.46 g. These decoction pieces were boiled and warm decoction was taken. According to ancient medical records, the formula always has the effect of nourishing Yin and relieving Qi of liver. It is used to treat syndrome of stagnation of liver-Qi and deficiency of liver-Yin and kidney-Yin, which can be seen with pain in chest, stomach and flank, acerbity and vomiting, dry throat and mouth, red tongue, weak pulse or deficiency of string and hernia. Here, the source, processing and others of Yiguanjian were clarified, providing a literature reference for the development and application of this famous classical formula.

Résumé

Objective:To explore the effect of α7 nicotinic acetylcholine receptor (α7nAchR) and changes of inflammatory factors during vagus nerve electrical stimulation in ischemic stroke model mice.Methods:Ninety SPF grade mice were randomly divided into sham operation+ vagus nerve electrical stimulation group (sham+ VNS group), model group (permanent middle cerebral artery occlusion group, pMCAO group), model+ vagus nerve electrical stimulation (pMCAO+ VNS group) and model group+ α7nAchR agonist group (pMCAO+ P group), model + vagus nerve electrical stimulation+ α7nAchR antagonist (pMCAO+ VNS+ A group), model+ vagus nerve electrical stimulation+ α7nAchR antagonist placebo group (pMCAO+ VNS+ AC group), with 15 mice in each group. The changes of vital signs of mice in each group were monitored during modeling.At 7, 14 and 21 days after successful modeling, neurological severity score (NSS) and adhesive removal test were used to evaluate the neurological deficit of mice.Immunofluorescence and Western blot were used to detect the expression of α7nAchR and its neural cell localization. ELISA was used to detect the level of TNF-α and IL-6. Prism 8.0 software was used for statistical analysis, and one-way ANOVA was used to analyze the physiological parameters during modeling.Repeated measurement ANOVA was used to compare the neurobehavioral score results, and t-test was used to compare the protein level and fluorescence intensity. Results:(1)The results of repeated measurement ANOVA showed that the interaction between group and time in NSS score was not significant ( F=0.91, P>0.05), and the group main effect ( F=46.68, P<0.05) and time main effect ( F=25.56, P<0.05) were significant. The results of Tukey's test showed that the NSS scores of pMCAO+ VNS group and pMCAO+ P group were significantly lower than those of pMCAO group (both P<0.05). There was no significant difference between pMCAO+ P group and pMCAO+ VNS group ( P>0.05). The NSS scores in pMCAO+ VNS+ A group were higher than that in pMCAO+ VNS group ( P<0.05), and significantly lower than that in pMCAO+ VNS+ AC group ( P<0.05). In the adhesive removal test, the interaction between group and time in the adhesive tape contact time and tear off time of mice was not significant ( F=0.67, 0.71, all P>0.05), and the group main effect ( F=30.12, 42.46, all P<0.05) and time main effect ( F=52.18, 47.34, all P<0.05) of mice in each group were significant.Tukey's test showed that the adhesive removal test on the 21st day, the adhesive tape contact time and tear off time of pMCAO+ VNS group were significantly shorter than those of pMCAO group (both P<0.05), and there was no significant difference between pMCAO+ P group and pMCAO+ VNS group (both P>0.05). (2)Western blot showed that compared with pMCAO group (0.36±0.01), the expression of α7nAchR in pMCAO+ VNS group (0.83±0.03) and pMCAO+ P group (0.67±0.02) increased ( t=13.53, 16.08, both P<0.01). The expression of α7nAchR in PCAO+ VNS+ A group (0.37±0.01) was significantly lower than that in PCAO+ VNS group ( t=12.88, P<0.01). Immunofluorescence results also showed that compared with pMCAO group (3.75±0.19), the expression of α7nAchR in pMCAO+ VNS group (8.96±0.48) and pMCAO+ P group increased (8.17±0.64) ( t=10.04, 6.67, both P<0.05). Immunofluorescence results also showed that compared with the pMCAO group (3.75±0.19), the expression of α7nAchR protein in the brain tissue of mice in the pMCAO+ VNS group and pMCAO+ P group increased ((8.96±0.48), (8.17±0.64), t=10.04, 6.67, all P<0.05). (3)The results of ELISA showed that compared with pMCAO group, the levels of TNF-a and IL-6 in serum and tissue supernatant of pMCAO+ VNS group and pMCAO+ P group were significantly lower than those of pMCAO group ( t=23.28, 15.30, 12.26, 11.08; all P<0.05). TNF in serum and tissue supernatant of mice in pMCAO+ VNS+ A group The levels of IL-6 in serum and tissue supernatant were significantly higher than those in pMCAO+ VNS group ( t=12.70, 11.01, 11.69, 17.37; all P<0.05) and pMCAO+ VNS+ AC group ( t=12.29, 11.07, 14.61, 29.27; all P<0.05). Conclusion:VNS may reduce inflammation by increasing the expression of α7nAchR protein in brain tissue, thereby playing a certain neuroprotective effect on ischemic stroke.

Résumé

Objective:To explore the effect of case-based learning (CBL) guided by ICF (International Classification of Functioning, Disability and Health) in rehabilitation practice teaching.Methods:Fifty-eight rehabilitation undergraduates who had practiced in the Department of Rehabilitation Medicine in The First Affiliated Hospital of Chongqing Medical University from February 2019 to December 2019 were randomized into observation group and control group. The observation group adopted ICF-guided CBL method for practice teaching, while the control group adopted traditional teaching methods. At the end of the internship, all the students were assessed in terms of their theoretical knowledge, case analysis and clinical practice ability. At the same time, questionnaires were used to conduct a satisfaction survey on the teaching method, and the results of the two groups were compared and analyzed by ttest and rank-sum test through SPSS 25.0. Results:The scores of the observation group were higher than those of the control group, with statistical significance ( P<0.05) . In the satisfaction survey, the observation group was superior to the traditional teaching method in terms of self-thinking ability and learning initiative, with statistical significance ( P<0.05). Conclusion:ICF-guided CBL method can strengthen students' independent thinking ability and learning initiative, and improve the students' clinical comprehensive ability of rehabilitation treatment.

Résumé

Objective:To understand the status and knowedge, attitude, practice(KAP) of adolescent sexually transmitted disease(STD) patients in Shanghai, and provide evidence for the development of health interventions. Methods:A cross-sectional study was conducted by anonymous interview survey using self-made questionnaires in patients during 2017.10.1-2017.12.31. Consecutive variables were analyzed using Mann-Whitney U test. Classification variables were analysed using Chi-square analysis and logistic analysis. Results:Regarding to sex and reproductive health, the knowledge awareness rate of STD patients was very low. The rate of correctly answering most questions was less than 5%. The patients were more open to risky sex, while the proportion of positive attitude towards safe sex was lower. Men were more open than women to risky sex. For example, 34.7% and 35.7% of men accepted homosexuality and one-night stand, respectively, but only 1.5% and 12.4% of women showed acceptance. There was statistically significant difference in knowledge scores of STD between different genders (P=0.020). The knowledge score of female patients was higher than that of male patients. There were statistically significant differences in unsafe sex and preventive health care attitudes among patients of different gender (P<0.001) and sex orientation (P<0.001). The attitudes of female patients were better than those of male patients, and the attitudes of heterosexual patients were better than those of sexual minorities. There was statistically significant difference in sexual behavior among patients with different sexual orientation (P=0.014), and the behavior score of sexual minority patients was better than that of heterosexual patients. The influencing factors of sex and reproductive knowledge were gender (P=0.001) and native place (P=0.004). STD knowledge level in females and Shanghai residents was higher than males and the non-residents. Conclusion:There is a large gender difference in adolescent STD groups in Shanghai. Women, floating population and sexual minorities are vulnerable groups and need more social support. More health education should be targeted on the factors affecting reproductive health knowledge, and adolescent STD prevention strategies should be formulated.

Résumé

OBJECTIVE@#To explore the application value of next generation sequencing (NGS) in preimplantation genetic diagnosis of α/β complex thalassemia couple.@*METHODS@#The coding regions of α-globin genes (HBA1, HBA2) and β-globin gene (HBB) were selected as the target regions. The high-density and closely linked single nucleotide polymorphism (SNP) sites were selected as the genetic linkage markers in the upstream and downstream 2M regions of the gene. After NGS, the effective SNP sites were selected to construct the haplotype of the couple, and the risk chromosome of the mutation carried by the couple was determined. The NGS technology was used to sequence the variations of HBA1, HBA2 and HBB directly and construct haplotype linkage analysis for preimplantation genetic diagnosis.@*RESULTS@#Direct sequencing and haplotype linkage analysis of HBA1, HBA2 and HBB showed that two of the six blastocysts were α/β complex thalassemia, one was β-thalassemia heterozygote, two were α-thalassemias heterozygotes, and one was intermediate α-thalassemia. A well-developed embryo underwent preimplantation genetic diagnosis was implanted into the mother's uterus, and a healthy infant was born at term.@*CONCLUSION@#Preimplantation genetic diagnosis can be carried out by NGS technology in α/β complex thalassemia couples, and abortion caused by aneuploid embryo selection can be avoided.

Résumé

Objective:To know the status of knowledge, attitude and behavior related to sexual and reproductive health in high school students in three regions of East China, and to provide a reference for adolescent reproductive health education. Methods:From August to October in 2019, 614 high school students were invited from 6 high schools in Jiading District and Yangpu District, Shanghai and Taicang City, Jiangsu to participate in this study. We conducted an anonymous self-questionnaire survey using structured questionnaires based on adolescent reproductive health knowledge and literacy. Results:The male to female ratio of all high school students in the study was 1∶1.25, and the average age was (16.1±0.9) years old. The score of pregnancy and abortion knowledge was the lowest among the reproductive health knowledge scores, and the differences among the three regions were statistically significant (P=0.002). Male high school students (P<0.001), students in the school with reproductive health education base (P=0.008) and students who wanted to obtain reproductive health education (P=0.002) were more acceptable to premarital sex. The high school students obtained adolescent health knowledge mainly through the internet or mobile phones, and had a demand for reproductive health related services. Conclusion:High school students in the three regions have a more open attitude towards premarital sex, but have a poor grasp of correct and efficient contraceptive knowledge. Responsible departments need to strengthen the health education of relevant knowledge, and at the same time to find new forms of education to effectively improve the level of adolescent reproductive health.
