Objective To investigate the incidence of follicular stimulating hormone receptor (FSHR) gene C566T mutation in Chinese women with premature ovarian failure (POF) and to explore the etiologies of POF. Methods This case-control study was carried out between 73 Chinese women with idiopathic POF (POF group) and 35 controls (control group), including 25 normal females with a regular menstrual history and 10 normal post-menopause women. DNA was extracted from the peripheral blood of patients and controls. The exon 7 of FSHR gene was amplified by PCR. PCR products were subsequently digested by the enzyme BsmI and then subjected to electrophoresis on agarose gels and stained with ethidium bromide to determine the C566T mutation. DNA samples of random sampling were further analysed by sequencing the PCR products to confirm the mutation. Results BsmI digestion resulting in two fragments of 51 and 27 base pairs was noted for all 73 POF patients and 35 controls. PCR sequencing confirmed that the 566 allele of FSHR gene is C, demonstrating normal FSHR allele. Conclusions No FSHR gene C566T mutation is present in POF patients and controls. FSHR C566T mutation may be rare in Chinese women with POF.

Objective To study the effect of clomiphene citrate (CC) and human menopausal gonadotropin (hMG) on the expression of integrins ? 4? 1 during implantation window in endometrium. Methods Endometrium integrin ? 4? 1 expression was detected by immunohistochemistry method in the mid secretory phase of 48 normal natural cycles. CC+hCG or CC+hMG+hCG cycles in 30 polycystic ovary syndrom (PCOS) patients and 48 normal women. Results The expression of endometrial integrin ? 4? 1 was stronger in the natural cycls than those of ovulation induction cycles with CC+hCG or CC+hMG+hCG. So was the pregnancy cycles as compared with the non pregnant cycles. Conclusion The endometrial receptivity in the min luteal phase and pregnant rate declined during ovulation induction by CC+hCG or CC+hMG+hCG in either normal women or PCOS patients.

Objective To study the expression of leptin and long form of leptin receptors (Ob R L) messenger ribonucleic acid (mRNA) and protein in endometrium during mid luteal phase of patients with polycystic ovary syndrome (PCOS) Methods The expession of leptin and Ob R L mRNA in endometrium during mid luteal phase from 15 normal controls and 14 PCOS related anovulatory patients who underwent ovulation induction therapy were studied by in situ hybridization, and levels of leptin and Ob R L protein were investigated by immunohistochemical methods Results The expression of Ob R L mRNA and protein in endometrial glands of most patients with PCOS were weak or moderate positive,whereas the levels of Ob R L mRNA and protein were moderate or strong positive in those of the controls,there was significant difference between the two groups; leptin mRNA and protein expression in enodmetrium of patients with PCOS and controls were not significantly different between the groups Conclusion The expression of Ob R L decreased in endometrium of mid luteal phase in patients with PCOS during induced ovulation,which may be related to low pregnancy rate of patients with PCOS.

Objective To study the radioprotective effect of polypeptide from Chlamys farreri (PCF) on ultraviolet B(UVB)-irradiated murine thmocytes in vitro. Methods The murine thymocytes were exposed to UVB radiation. MTT method was used to detect the cell viability. The activities of intracellular glutathione peroxidase (GSH-Px), superoxided dismutase(SOD) and catalase (CAT) were measured. Intracellular reactive oxygen species (ROS) and the effect of PCF on UVB-induced apoptosis were investigated by flow cytometry. Results PCF could greatly enhance the viability of murine thymocyte and markedly promote the activities of GSH-Px, SOD and CAT, while the amount of ROS was decreased. PCF could inhibit UVB-induced thymocyte apoptosis. Conclusion PCF has significant radioprotective effects on UVB-irradiated murine thymocytes in vitro.

Objective To provide nutritional supportive scheme for patients with radiation injury through the treatment of the one exposed to Nanjing 192Ir source accident.Methods The reasonable nutrition treatment scheme was made on the basis of dietary survey and nutritional index monitoring during clinical stages of the patient,including body weight,body mass index(BMI),biochemical indexes,electrolyte,etc.,as well as metabolic cart determination of resting energy expenditure (REE).Results Patient on admission (days 5 post-irradiated) weighing 42.5 kg,172 days after the first irradiated (the first skin grafting) fell to a minimum of 36 kg,then gradually rise,hen rose back to normal range on days 383 before discharge.Normal admission hemoglobin was 135 g/L,172 d after irradiated to a minimum of 54 g/L,normal discharge;when lymphocytes admission low as 0.5 × 109/L,58 days back to normal after exposure,172 days after irradiated down to 0.4 × 109/L.Serum albumin was normal admission 41.2 g/L,172 days after irradiated down to 25.3 g/L.The normal level of serum prealbumin was 0.22 g/L,248 days to a minimum of 0.04 g/L,the basic return to normal at discharge was 0.17 g/L.Admission normal liver function,bilirubin index slightly higher,the all in one parenteral nutrition after about 2.5 months later,bilirubin and liver function indicators were gradually increased,the adjusted treatment and nutrition liver and gallbladder and other gradually returned to normal after treatment.REE and the body weight were determined by metabolic cart on days 294,308 and 342 for the energy requirements.Conclusions For patient with radiation injury,appropriate nutrition therapy is a key method for the clinical treatment and rehabilitation,which can maintain the nutritional status of patients and improve clinical treatment.

Objective To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. Methods A total of 226 advanced schistosomiasis patients with ascites were randomly di?vided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing,while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed,and the quality of life of the patients before and after hospital discharge was assessed. Results The improvement rate,satisfaction degree,and awareness rate of health knowledge of the patients in the experiment group were 93.8%,100%and 97.4%,respectively,which were significantly higher than those of the control group(all P<0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%,respectively,which were significantly lower than those of the control group(both P<0.05). In addi?tion,the average hospitalization days and the hospitalization cost of the experiment group were(12.2 ± 0.7)d and(4 725.0 ± 310.1)Yuan respectively,which were less than those of the control group(both P<0.01). When 6 months after the discharge from hospital,the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group(all P<0.05). Conclusions The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites;meanwhile,it can short?en the hospitalization time and save the hospitalization cost. Therefore,this nursing model is suitable for popularization and ap?plication in the treatment and nursing work of the advanced schistosomiasis assistance.

Objective:To investigate the effect of applying foam dressing combined with self-made adhesive penile hood fixation in children after circumcision.Methods:A total of 101 cases of children who received circumcision from January to December 2020 in the urology department of the People′s Hospital of Xuancheng City were selected. The patients were randomly divided into experimental group (50 cases) and control group (51 cases). In the experimental group, the incision was wound with foam dressing combined with the self-made adhesive penile hood fixation method, while in the control group, the incision was wound with the conventional sterile gauze dressing combined with the simple plastic basket fixation method.The postoperative incision bleeding, prepuce edema, incision pain, incidence of complications and the satisfaction of the children′s family members on postoperative dressing and fixation were compared between the two groups.Results:The incidence of prepuce edema in the experimental group was 88.00% (44/50), 12.00% (6/50), 0, which in the control group was 43.14% (22/51), 45.10% (23/51), 11.76% (6/51), and the difference between the two groups was statistically significant ( Z= -4.80, P<0.05). In the experimental group, pain score at 24 hours after operation and at the time of dressing change were 3.50 ± 1.04, 2.48 ± 0.54, respectively, which were lower than that of the control group 5.31 ± 1.36 and 7.12 ± 0.97, and the difference between the two groups was statistically significant ( t=7.53, 29.66, all P<0.05). The incidence of postoperative infection and urinary retention in the experimental group were 0 and 2.00% (1/50), respectively, which were lower than 7.84% (4/51) and 7.84% (4/51) in the control group, and the difference between the two groups was statistically significant (Fisher′s exact probability method, P<0.05). The degree of family satisfaction in the experimental group was 96.00% (48/50), which was higher than that in the control group (78.43%, 40/51), and the difference between the two groups was statistically significant ( χ2=6.95, P<0.05). Conclusions:The application of foam dressing combined with pasting penile hood after circumcision can reduce the degree of foreskin edema, pain and the incidence of complications, and improve the satisfaction of the children′s family members.

Objective:To analyze the risk factors of postpartum type 2 diabetes (T2DM) in patients with family history of diabetes mellitus with gestational diabetes mellitus (GDM).Methods:From January 2017 to January 2019, 275 patients with GDM and family history of diabetes were selected. According to the occurrence of postpartum T2DM, the patients were divided into postpartum normal group (207 cases) and postpartum disease group (68 cases). The clinical data of the two groups were compared, and the independent risk factors of postpartum T2DM were analyzed by logistic regression, and a line chart prediction model was constructed. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive ability of the model. X-tile software was used to obtain the integral truncation value of the line graph model, and survival curve was drawn and internal verification was carried out.Results:Of 275 GDM patients, 68 had T2DM after delivery, with a incidence rate of 24.73%. There were significant differences between the two groups in age, body mass index (BMI) before pregnancy, weight gain during pregnancy, fasting blood glucose during pregnancy and glycosylated hemoglobin during pregnancy (all P<0.05). There was no significant difference in pregnancy outcome between the two groups ( P>0.05). Age≥30 years, high pre-pregnancy BMI, weight gain≥6 kg during pregnancy, fasting blood glucose>5.8 mmol/L during pregnancy, and glycosylated hemoglobin>5.2% during pregnancy were independent risk factors for postpartum T2DM in GDM patients with diabetes family history (all P<0.05). The nomogram model predicted that the C-index value of postpartum T2DM was 0.912 (95% CI: 0.854-0.960), and the area under the ROC curve was 0.799 (95% CI: 0.742-0.856), with good discrimination; The calibration curve indicated that the accuracy of the model was good. According to the integral cutoff value of the line chart model, the probability of postpartum T2DM in GDM patients with family history of diabetes was divided into three groups: low (≤67.24 points), medium (>67.24 points and ≤129.82 points) and high-risk groups. The incidence rate of postpartum T2DM were 13.71%, 29.29% and 59.62%, respectively, with statistical significance (all P<0.05). Conclusions:Age≥30 years old, high pre-pregnancy BMI, pregnancy weight gain≥6 kg, pregnancy fasting blood glucose>5.8 mmol/L and pregnancy glycosylated hemoglobin>5.2% were independent risk factors for postpartum T2DM in GDM patients with family history of diabetes.

Nutcracker syndrome complicated with chronic kidney disease is easy to be missed clinically.We report a case of nutcracker syndrome (NCS) complicated with IgA nephropathy, and summarize the clinical features of nutcracker syndrome complicated with chronic kidney disease.Through literature search, we found that Nutcracker with chronic kidney disease is not rare.We think that we should pay attention to the possibility of chronic kidney disease when Nutcracker (+ ) is combined with persistent or massive proteinuria, and percutaneous renal biopsy is helpful for the diagnosis and treatment.
