Objective To evaluate the effectiveness of treating glioma in combination with drugs multiply by comparing the size of tumor and the survival time of different groups in rat glioma after targeted blood-brain barrier (BBB ) disruption by MRI-guided focused ultrasound.Methods The stereotaxis instruments and the 10 μl gas-tight syringes were used to inject gliosarcoma cells into the targeted area of the brain in 50 male Sprague-Dawley rats.The glioma-bearing rat model was established.Each rat received either:(1 )no treatment (control;n =8);(2)single liposomal doxorubicin (DOX;n = 10);(3)multiple DOX (n =10);(4)single Avastin (AVS)and DOX (n =10);(5)multiple AVS and DOX (n =10).The SonoVue microbubble ultrasonic contrast agent and DOX or AVS were injected into the tail vein respectively on day 12 after implantation.The tumor size was measured by MRI on pre-treatment,immediacy and once a week of post-treatment after targeted BBB disruption by focused ultrasound,and the life span in rat glioma was recorded.Results The mediam survival of different groups in rat glioma(The range of the life span 13-90 d):no treatment (7 d);single DOX (12 d);multiple DOX (1 5 d);single AVS + DOX (22 d), multiple AVS+ DOX (30 d).There was significant difference of the groups on mediam survival comparison (P < 0.01 ).The tumor growth pattern after post-treatment of different groups in rat glioma except control:single DOX was noticeable fast and multiple AVS+DOX was visibly delayed comparable to other groups,and finally the tumor size of multiple AVS + DOX even became small.Conclusions The microbubble blasting enhances the local tissue permeability and promotes the drug delivery of chemotherapy and anti-angiogenesis locally in glioma-bearing rats by MRI-guided focused ultrasound.Especially,the combination with drugs multiply has a synergism efficacy that may enhance the effectiveness of chemotherapy,reduce tumor growth,and even become small of the tumor size,and increase survival time significantly after BBB disruption.

Objective To investigate the relationship between the serum SRC-3 levels and the bone loss severity in postmenopausal women. Methods Fifty-eight PMW with osteopenia or osteoporosis and nineteen healthy PMW were enrolled in this study from June 2012 to September 2013. BMD at the lumbar spine and femoral neck were observed by DXA Lunar Prodigy Vision. The levels of serum SRC-3 were detected by ELISA. The diagnosis value was evaluated by the ROC curves analysis. Results The levels of serum SRC-3 were significant higher in the normal group than those in the osteopenia or the osteoporosis groups (P<0.001 for both), no statistical significance was found between the osteopenia and the osteoporosis group(P=0.056). The levels of serum SRC-3 were negatively correlated with the BMD diagnosis grading (r=-0.543, P < 0.001). By using the ROC curve analysis, the serum level of SRC-3 for PMW with osteoporosis and osteopenia were found to be 0.297 ng/mL and 0.347 ng/mL, respectively. The levels of serum SRC-3 were positively associated with BMI (r=0.395, P<0.001) and LS-BMD (r=0.503,P<0.001) in the postmenopausal women. Conclusion SRC-3 might be an useful index to reflect the severity of lumbar spine bone loss.

Objective To evaluate the effectiveness of treating glioma in combination of two kinds of drugs by comparing the size of tumors and the survival time of different groups in rat glioma after targeted blood‐brain barrier (BBB) disruption by focused ultrasound under MRI‐guide. Methods The stereotaxis instruments and the 10 μl gas‐tight syringes were used to inject gliosarcoma cells into the targeted area of the brain in 40 male Sprague‐Dawley rats. The glioma‐bearing rats models were established. Rats were divided into 4 groups to receive different treatment :(1) no treatment (control, n = 8), (2) IV Avastin (Avastin only, n =10), (3) IV liposomal doxorubicin (DOX only, n =10), (4) IV Avastin and liposomal doxorubicin (Avastin+DOX, n =10). The SonoVue microbubbles and DOX or Avastin were injected into the tail vein respectively on the 12th day after implantation. The tumor size was measured by MRI on immediacy, once a week after targeted BBB disruption by focused ultrasound, and the life span in rat glioma was recorded. Results The average survival time of different groups in rat glioma was as follows :no treatment(17 ± 4)d, Avastin(20 ± 4)d, DOX(25 ± 5)d, DOX+ Avastin(40 ± 5)d. The tumor size after post‐treatment of different groups in rat glioma was as follows :no treatment(5 7.0 ± 4 3.0)mm, Avastin(4 3.0 ± 2 5.0)mm, DOX(4 1.2 ± 3 1.0)mm, DOX + Avastin(2. 20 ± 1. 30)mm. There was significant increased in average survival time and decreased in tumor size after a combination treatment DOX+ Avastin compared with other groups( P < 0 0.1). Conclusions The microbubble blasting by MRI‐guided focused ultrasound enhances the local tissue permeability and promotes the drug delivery of chemotherapy and anti‐angiogenesis locally in glioma‐bearing rats. Especially, the combination of two kinds of drugs has a synergism efficacy that may reduce tumor growth and increase survival time significantly after BBB disruption.

Objective To investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

Objective: To investigate the intake of liquid dairy products and identify its influencing factors among the fourth grade students in Nanjing City. Methods: The fourth grade students were selected as the study subjects in Nanjing City using a multi-stage random cluster sampling method in September 2020. Their general information, frequency of liquid dairy product intake one week prior to survey and mean intake amount per time were collected. According to the 2016 Dietary Guidelines for Chinese Residents, weekly intake of liquid dairy products of 2 100 g and greater was defined eligible. Factors affecting the frequency and amount of liquid dairy product intake were identified using multivariable logistic regression analysis. Results: A total of 2 268 questionnaires were allocated and 2 216 valid questionnaires were recovered, with an effective recovery rate of 97.71%. The respondents included 1 199 boys ( 54.11% ) and 1 017 girls ( 45.89% ). The frequency of liquid dairy product intake was (6.41±4.86) times per week, and the median intake amount was 1 250.00 g per week (interquartile range, 1 750.00 g per week). There were 607 students ( 27.39% ) consuming liquid dairy products of 2 100 g and greater a week, and 1 016 students ( 45.85% ) consumed liquid dairy products for 7 times and more a week. Multivariable logistic regression analysis showed that living in urban areas ( OR=1.204, 95%CI: 1.005-1.443 ), knowing nutrition labels ( OR=1.221, 95%CI: 1.021-1.460 ), periodical measurement of body weight (OR=1.486, 95%CI: 1.098-2.011) and restricted intake of sugar-containing drinks ( OR=1.264, 95%CI: 1.005-1.590 ) facilitated the intake of liquid dairy products for 7 times and more a week, and students with periodical measurement of body weight were more likely to consume liquid dairy products for 2 100 g and greater a week ( OR=1.821, 95%CI: 1.240-2.676 ). Conclusions Inadequate intake of liquid dairy products is found among the fourth grade students in Nanjing City. Residence, awareness of nutrition labels, periodical measurement of body weight, and parental restriction of sugar-containing drink intake affect the intake of liquid dairy products.

Objective:To investigate the joint associations of smoking and insufficient physical activity with hypertension, diabetes and dyslipidemia in male adults.Methods:Based on the data from the 2017 Nanjing Chronic Diseases Risk Factors Surveillance Program, 61 098 Nanjing residents aged 18 and older was randomly recruited from 12 districts, using the multi-stage stratified cluster sampling method. Information about smoking behaviors, physical activity and chronic disease-related indicators within the first 12 months before the survey was obtained through questionnaires.Results:Among the 29 848 valid male samples, the proportions of non-smokers, current smokers and ex-smokers were 59.6%, 37.2% and 3.2%, and the proportions of those who had physically active<600 MET-min/w (insufficient physically active) and ≥600 MET-min/w (adequate physically active) were 18.8% and 82.2%, respectively. In non-smokers, current smokers and ex-smokers, the prevalence of hypertension was 24.7%, 34.0% and 43.8%, and the prevalence of diabetes was 8.8%, 12.3% and 16.5%, and the prevalence of dyslipidemia was 26.8%, 36.1% and 41.9%, respectively. Multivariate logistic regression analysis showed that current smokers had a higher risk of hypertension ( OR=1.164, 95% CI: 1.086-1.248), diabetes ( OR=1.324, 95% CI: 1.207-1.452), and dyslipidemia ( OR=1.291, 95% CI: 1.216-1.371) than non-smokers in male adults. Compared with people who had adequate physical activity, someone with insufficient physical activity had higher hypertension ( OR=1.452, 95% CI: 1.331-1.583), diabetes ( OR=1.170, 95% CI: 1.041-1.315) and dyslipidemia ( OR=1.245, 95% CI: 1.158-1.338). And current smokers with insufficient physical activity had the highest risk of hypertension ( OR=1.749, 95% CI: 1.550-1.974), diabetes ( OR=1.363, 95% CI: 1.165-1.595), and dyslipidemia ( OR=1.614, 95% CI: 1.461-1.782) in male adults. Conclusions:Smoking and insufficient physical activity are risk factors for hypertension, diabetes, and dyslipidemia. People who is characterized by smoking together with insufficient physical activity presents with increased risk on developing hypertension, diabetes, and dyslipidemia.

Objective: To compare the clinical value of total gastrectomy and proximal gastrectomy in the treatment of gastric fundus carcinoma. Methods: 80 patients with gastric fundus cancer were divided into observation group and control group according to the random number method.The observation group was treated with total gastrectomy, and the control group was treated by proximal gastrectomy.The operation-related conditions, such as operation time, intraoperative bleeding and postoperative anal exhaust time of the two groups were compared.After surgery R0 resection rate and 2-year survival rate were analyzed. Results: The operative time in the observation group was (86.3±1.9)min, which was shorter than (102.3±2.6)min in the control group (t=31.424, P<0.05). The intraoperative blood loss of the observation group was (180.5±15.0)mL, which was less than (230.0±25.0)mL of the control group (t=10.738, P<0.05). The anal exhaust time of the observation group was (41.5±2.1)h, which was shorter than (56.9±3.3)h of the control group (t=24.900, P<0.05). The percentage of pathologic R0 resection of the observation group was 32.5%(13/40), which was higher than 5.0%(2/40) of the control group (χ²=8.205, P<0.05). The 1-year survival rate and 2-year survival rate in the observation group were 92.5%, 67.5%, respectively, which were significantly higher than those in the control group(60.0%, 42.5%, χ²=4.943, 5.051, all P<0.05). Conclusion Compared with the proximal gastrectomy, the total gastrectomy in the treatment of gastric fundus carcinoma has shorter operation time, less intraoperative blood loss, quicker postoperative recovery, higher pathologic resection rate and survival rate.
