BACKGROUND: The postnatal sexual health of women is crucial in reproductive health, due to lack of sexual knowledge and sexual heath care service as well as conventional idea, the medical staff and postnatal women themselves pay little attention and discussion on the sexual health after childbirth.OBJECTIVE; To investigate the prevalence and types of women's sexual problems after childbirth, identify the factors associated with dyspareunia and investigate the status quo of postnatal sexual health care service. DESIGN: Cross-sectional study and follow-up survey within six months after delivery.SETTING: Department of Reproductive Medicine, Chongqing University of Medical Sciences. PARTICIPANTS: A total of 798 primiparous women delivering a live birth in Department of Obstetrics at the First Affiliated Hospital of Chongqing University of Medical Sciences between November 2000 and July 2001, and 79 husbands who accompanied their wives during the follow-ups were adopted in this study.METHODS: The primiparous women after 6 months of childbirth and husbands conducted routine postnatal follow-ups and were informed of the follow-up content. The interview was used in this cross-sectional study and the questionnaires were finished under the help of health professional. And some advice, consultations and treatments can be given in time. MAIN OUTCOME MEASURES; ①main change of postnatal sexual life;②postnatal sexual problems and related factors. RESULTS: Totally 460 out of 798 primiparous women in accordance with the inclusive and exclusive criterions received follow-up surveys after telephone or letter notification. ①Main change of postnatal sexual life: Of the 460 respondents, 94.74% had resumed sexual activity within six months after delivery. Compared with one year pre-pregnancy, the number of sexual activity decreased obviously within 3-6 months after delivery, and 66.0％ of postnatal women decreased the sexual desire.②Postnatal sexual problems and related factors: Sexual morbidity increased significantly after the childbirth: In the first three months after delivery, 70.6％ of women experienced sexual problem(s), declining to 55.6％ during the 4th-6th months, and reduced to 34.2％ at the 6th month, but not reaching pre-pregnancy levels of 7.17％. The sexual problems of women after delivery included dyspareunia, vaginal dryness, orgasm disorder and vaginal relaxation, etc.4. And dyspareunia was the most common type. Between the 4th and 6th month after delivery, dyspareunia was significantly associated with the effect of traditional sexual ideas, experience of dyspareunia before pregnancy and current breastfeeding (P ＜ 0.05), while the association of dyspareunia with delivery mode was not significant.③Sexual care service and sexual counseling after delivery: Only 20.8％ of women received information about sexual health from health care personnel within 42 days after delivery, and consultation rate of sexual intercourse problems was 8.0％.④Husbands' comprehension of postnatal problems in women: Only 59.2％ of partners whose wives had postnatal sexual problem(s) knew that their wives had ever experienced sexual problem(s) and 8.1％ of partners had sought medical help. CONCLUSION; Sexual health problems are very common in women after childbirth, taking up for 70.6％. And the quality of postnatal sexual health is unrelated with delivery mode, but postnatal health care service are often overlooked, additionally lack of professional counseling and treatment. The current practices of encouraging the husband's supports after the childbirth may well influence the prevention and treatment of postnatal sexual problems in women.

Objective To investigate the relationships between aspirin resistance (AR) and laboratory indexes and different types of traditional Chinese Medicine(TCM)syndrome in patients with acute cerebral infarction. Methods Two hundred and eight different types of TCM syndromes of patients with acute cerebral infarction admitted from January 2012 to November 2013 in the Neurology Department of Shanghai Seventh People's Hospital were divided into AR group and aspirin sensitive(AS)group according to the rate of AR. Simultaneously,28 healthy volunteers in the same period were assigned in a healthy control group. The changes of red blood cell volume distribution width coefficient of variation(RDW-CV),platelet count(PLT)and homocysteine(Hcy)levels were observed in the three groups. The correlation between different types of TCM syndromes and AR,PLT,RDW-CV,and Hcy was analyzed by non-conditional logistic regression. Results The total incidence of AR was 29.32%(61/208)in 208 patients with acute cerebral infarction. There were 165 cases with Qi deficiency and blood stasis syndrome,the incidence of AR being 26.06%(43/165);32 cases with wind phlegm obstructing channel syndrome,the incidence of AR, 43.75%(14/32);11 cases with liver yang hyperactivity syndrome,the incidence of AR,36.36%(4/11);in the comparisons,the incidence rates of AR among the above types of syndromes had no statistical significant differences (P>0.05). Compared with the healthy control group,the levels of PLT,RDW-CV,Hcy in AR group and AS group of various types of TCM syndrome were increased,the PLT and RDW-CV levels in patients with Qi deficiency and blood stasis syndrome in AR group were more significantly elevated in the comparisons between AR and AS groups, there were statistical significant differences〔PLT (×109/L):212.16±66.48 vs. 187.54±56.85, RDW-CV:(14.34±3.16)% vs.(13.20±2.16)%,both P<0.05〕;the level of Hcy in patients with wind phlegm obstructing channel syndrome in AR group was increased more significantly than that in AS group,the difference between the two groups being statistically significant(μmol/L:27.29±18.64 vs. 21.36±14.61,P<0.05). Logistic regression analysis showed,increased PLT〔odds ratio(OR)=1.007 2,95%confidence interval(CI):1.001 2-1.013 2,P=0.018 5〕and RDW-CV〔OR=1.165 4,95%CI:1.007 9-1.347 4,P=0.038 8)was independence risk factor of AS development. Conclusion The elevation of RDW-CV,PLT,Hcy in level reflects the index of AR production, especially in patients with acute cerebral infarction accompanied by Qi deficiency and blood stasis syndrome and wind phlegm obstructing channel syndrome.

Objective To explore the preventive effect of the supplemental dietary boron on bone damage of rats with excess fluoride (EF) ingestion. Methods Twenty-four Sprague-Dawley rats aged 4-5 weeks old were divided into the control (C group, treated with distilled water and the elementary dietary), the excessive fluoride dose group (EF group, treated with distilled water with 100mg/L F-from 221.0g NaF per liter and the elementary dietary) and the boron prevention group (P group, treated with 100mg/L F-distilled water and the supplemental boron dietary). Three months after the experiment, fluorine, boron contents and AKP activities in serum, total RNA and fluorine contents in bone, vertical and transverse diameter and dry weight of tibias of rats were assayed, and bone biomechanics of femur and bone mineral density (BMD) were determined. Results Compared with those in the C group, fluorine contents in serum and bone, AKP activities in serum of rats in the EF group significantly increased; total RNA in bone and BMD of the bone of whole body and tibia decreased, vertical and transverse diameter of tibias was shortened, dry weight was decreased; peak load of femur increased but maximum deformation decreased. Compared with those in EF group, fluorine contents in serum and bone, AKP activities in serum of rats in the P group obviously decreased; total RNA in bone and BMD of whole body, lumbar vertebrae and tibias notably increased, vertical and transverse diameters and dry weight of tibia were enhanced, peak load of femur was obviously raised. Boron contents in serums of rats in three groups had no significant differences. Conclusion Bone damage obviously occurred in rats with EF intake, and the supplemental dietary boron had a preventive effect on these changes.

Objective:To study the effect of early immune enteral nutrition combined with glutamine (Gln) parenteral nutrition on T-lymphocyte subsets in patients with severe pulmonary infection in the intensive care unit (ICU).Methods:A total of 70 ICU patients with severe pulmonary infection who were treated in Yinzhou People′s Hospital from January 2017 to October 2019 were selected, and the patients were divided into enteral nutrition group and combined group according to a completely random method with 35 cases in each group. Both groups of patients were given conventional treatment; patients in the enteral nutrition group was given immunoenhanced enteral nutrition on the basis of conventional treatment, and those in the combined group was given Gln on the basis of enteral nutrition group. The levels of arterial oxygen partial pressure (PaO 2), arterial oxygen saturation (SaO 2), arterial partial pressure of carbon dioxide (PaCO 2), CD 8+, CD 3+, CD 4+/CD 8+, procalcitonin (PCT), hypersensitive C-reactive protein (hs-CRP) and tumor necrosis factor alpha (TNF-α) before and after treatment were detected and compared between two groups. The treatment efficacy was compared between two groups too. Results:After treatment, the levels of SaO 2 and PaO 2 in combined group were higher than those in enteral nutrition group, the level of PaCO 2 in combined group was lower than that in enteral nutrition group, but there were no significant differences ( P>0.05). After treatment, the levels of CD 3+, CD 4+/CD 8+ in combined group were higher than those in enteral nutrition group [(62.37 ± 6.15)% vs. (59.35 ± 5.24)%, 1.50 ± 0.18 vs. 1.12 ± 0.11], the level of CD 8+ in combined group was lower than that in enteral nutrition group [(33.15 ± 6.11)% vs. (37.72 ± 8.57)%], and there were significant differences ( P<0.05). The levels of PCT, hs-CRP and TNF-αin combined group were lower than those in enteral nutrition group [(3.83 ± 0.82) μg/L vs. (6.47 ± 1.34) μg/L, (6.92 ± 1.25) mg/L vs. (12.72 ± 3.83) mg/L, (92.35 ± 13.05) ng/L vs. (125.26 ± 18.35) ng/L], and there were significant differences ( P<0.05). The total effective rate in combined group was higher than that in enteral nutrition group [88.57%(31/35) vs. 65.71%(23/35)], and there was significant difference ( χ2=5.185, P<0.05). Conclusions:Early immune enteral nutrition combined with Gln parenteral nutrition has significant effects on patients with severe pulmonary infection in ICU, and can improve the level of T-lymphocyte subsets, control infection, and reduce inflammatory factor levels.

Objective To explore the effect of cognitive education and behavioral intervention in solid-state high resolution esophageal manometry (HRM) examination. Methods From April 2016 to June 2017, 60 patients with solid-state HRM in the gastrointestinal motility room at the First Affiliated Hospital of Jiaotong University were as the research object. The 60 patients were divided into control group and experimental group with 30 cases each by the method of random numbers. The conventional methods was used in control group to conduct informed counseling before the examination and the coordination guidance in the examination. The conventional methods and cognitive behavioral intervention was used in experimental group at the same time. The successful rate of intubation, the time used for the examination, discomfort symptoms during intubation, the patient's satisfaction in the whole check process and self-evaluation of intubation pain experience in two groups of patients were compared. Results The time used in the experimental group examination was (28.50±8.75) min, and the control group was (33.13± 5.49) min. The difference between the two groups was statistically significant (t=2.584, P=0.015). In the experimental group, the number of nausea, vomiting, and coughing in the intubation process was 11, 0, and 1, respectively, and the control group was 20, 6, and 7, respectively. The difference was statistically significant (χ2=5.406, 4.630, 5.192, all P<0.05). In the experimental group, the scores of the 2, 3, 4, 5, 7, 8, 10, 11, 12, and 13 items of the intubation pain experience self-evaluation in the examination process were (1.00 ± 0.64), (1.37 ± 0.85), (2.80 ± 0.96), (1.50 ± 0.51), (0.87 ± 0.63), (0.77 ± 0.50), (0.60 ± 0.56), (1.07 ± 0.25), (0.57 ± 0.57), (1.50 ± 0.63) points, and the 2, 3, 4, 5, 7, 8, 10, 11, 12 and 13 scores of the control group they were (1.50 ± 0.51), (2.03 ± 0.76), (3.50 ± 0.82), (2.03 ± 0.76), (1.20 ± 0.61), (1.03 ± 0.41), (0.83 ± 0.53), (1.23 ± 0.43), (0.87 ± 0.57), (2.00 ± 1.05) points, respectively. The difference was statistically significant (t=-4.130--2.140, all P<0.05). Conclusions HRM is an important test before the clinical application of a wide range of clinical applications for the detection of esophageal motility disorders and gastroesophageal reflux disease. The degree of patient cooperation with the operation directly affects the high-resolution esophageal manometry test results and self-experience. Medical staff can give patients cognitive education and behavioral intervention before examination, which can effectively reduce the symptoms and pain caused by intubation, improve patient compliance, shorten the time for examinations, improve work efficiency, and improve patient satisfaction. It is worth further promotion and application in clinical examination.

Background: /Aim: It is known that an imbalance in the intestinal f lora plays a crucial role in colorectal cancer (CRC), but the effect of food consumption patterns on the types of intestinal flora remains to be clarified. We aimed to analyze the associations between food intake and intestinal flora in healthy and CRC individuals. Methods: Food intake data were recorded using the Food Frequency Questionnaire (FFQ). The composition and diversity of the intestinal flora detected by 16S rRNA gene sequencing, and the data were analyzed by R version 3.1.1 software. Results: Higher intake of red meat or pickled foods, and lower intake of white meat, fruits, vegetables, beans, nuts were found in the CRC group compared with the healthy group. Higher levels of Fusobacteria and Proteobacteria, and lower levels of Firmicutes were observed in the CRC group. Partial correlation analysis revealed that the intake of fruits, beans, and nuts was negatively correlated with Proteobacteria and Fusobacteria, but pickled food was positively correlated with Fusobacteria (p < 0.05). Fish, beans, and nuts intake was negatively correlated with Escherichia (p = 0.01). Multiple regression analysis revealed that vegetable oil (odds ratio [OR], 0.26; 95% confidence interval [CI], 0.13 to 0.82), vegetables (OR, 0.26; 95% CI, 0.10 to 0.64), eggs (OR, 0.26; 95% CI, 0.10 to 0.69), pickled foods (OR, 21.02; 95% CI, 6.02 to 73.45), and red meat (OR, 4.23; 95% CI, 1.68 to 10.60) had an impact on CRC risk. Conclusions The species and abundance of intestinal flora varies between CRC and healthy individuals and may be affected by their food preference.

This study aims to investigate the effect of transmembrane protein angiotensin converting enzyme 2 (ACE2) on the prognosis of breast cancer and its potential mechanism.Public databases were used to analyze ACE2 expression and its relationship with clinicopathological features and prognosis of breast cancer patients, combined with in vitro experiments to analyze the mechanism of action and immune relevance of ACE2 in breast cancer.Results showed that the expression of ACE2 in breast cancer tissues was significantly lower than that in normal breast tissues, and that its expression was negatively correlated with age, M stage and N1mi stage of breast cancer patients (P < 0.05).Patients with Luminal type breast cancer with high ACE2 expression had poor prognosis, while in the triple-negative breast cancer (TNBC) subtype, ACE2 showed different prognostic significance.In addition, ACE2 is closely associated with the metabolic and immune microenvironment of tumor tissue.In vitro experiments have shown that ACE2 is lowly expressed in MDA-MB-231 cells and may inhibit cell progress by downregulating matrix metalloproteinase 2（MMP2）.The results suggest that the low expression of ACE2 in breast cancer is closely associated with patient prognosis as well as metabolic and immune microenvironment, and that ACE2 may inhibit TNBC cell progress through the MMP2 pathway.
