Objective To study the effects of repetitive transcranial magnetic stimulation (rTMS) combined with hyperbaric oxygen (HBO) therapy on the recovery of neurological functional after cerebral infarction,and to discuss its possible mechanism.Methods Forty-five patients with cerebral infarction were randomly divided into a control group,an rTMS group and an rTMS plus HBO group,each group with 15 patients.The patients in the two treatment groups received 1 Hz rTMS to inhibit the unaffected hemisphere and 3 Hz rTMS to stimulate the affected hemisphere.One of the treatment groups also received HBO therapy,14 daily sessions.The National Institutes of Health stroke scale (NIHSS) and the Barthel index (BI) were evaluated on the 1st,14th and 30th day of treatment.Results The neurological function scores of those in the rTMS group and the rTMS & HBO group improved significantly.On the 1st and 14th day,no significant difference in NIHSS or BI scores was observed among the three groups,but by the 30th day the average neurological functional score in the rTMS & HBO group had improved significantly compared with the control group.The rTMS plus HBO group showed significantly better improvement than the rTMS group in terms of BI scores,but no significant difference in average NIHSS and BI scores was observed between the rTMS group and the control group.Fifteen days after the treatments had finished,the follow up results showed the improvements of the patients in the rTMS plus HBO group were significantly better than those in the other groups.Conclusion For patients with cerebral infarction,rTMS combined with HBO therapy can improve neurological function more significantly than rTMS therapy alone.

Objective Even after successful surgical repair,patients with coarctation of the aorta (CoA) are at high risk of long-term morbidity and mortality due to cardiovascular events,which is probably related to persistent arterial disfunction during long-terr follow-up after operation,The aim of the study was to explore the alterations of vascular structure and function in children with successfully repaired CoA in the short-and mid-term follow-up.Methods A cohort of 20 children who underwent CoA repair between January 2010 and October 2010 in Guangzhou women and children's Medical Center was studied.There were 14 males and 6 females in CoA group,which comprised 6 patients with isolated CoA,14 patients with CoA associated with intracardia anomalies,whose median age of operation was 4 months (rang from lmonth to 10.0 years).And 20 patients with isolated ventricular septal defect (VSD) were included as VSD group during the same time,with 12 males and 8 females,whose median age of operation was 5 months (rang from 1 month to 12.0 years).Resting blood pressure,flow-mediated dilation (FMD) of the brachial artery,carotid intima-media thickness (IMT) were compared in CoA group and VSD group,including preoperative media data and follow-up of 1 month,6 months and 1 year.In addition,as comparison to the operation group,20 health children with normal echocardiographic findings,whose median age was 5 months (rang from 3 month to 10.0 years),were selected as health group for the 1-year following up.None of them had obesity,hyperlipidemia,diabetes mellitus,metabolic diseases or systemic inflammatory disease.Results As a result of the datas before operation and those I month,6 months and 1 year after operation,all children were normotensive at rest.In the same period,Carotid IMT in CoA group[(0.47 ± 0.10)mm,(0.49 ±0.10) mm,(0.57 ±0.07)mm,(0.61 ± 0.07) mm]was significantly thicker than that in VSD group[(0.41 ±0.11) mm,(0.43 ±0.11)mm,(0.51 ±0.08) mm,(0.55 ±0.08) mm](P＜0.05) and health group[(0.40 ±0.09) mm,(0.42 ±0.11)mm,(0.50 ±0.08) mm,(0.57 ±0.08) mm](P ＜0.05),Brachial artery FMI in children with CoA[(5.4,6 ±1.51)％,(5.71 ±1.88)％,(5.42±1.69)％,(5.27±1.02)％]was significantly lower than that in the VSD control group[(6.69±1.45) ％,(6.66±1.21)％,(6.81 ±1.03)％,(6.43±1.34)％](P＜0.05) and health group[(6.59 ±1.84)％,(6.84±1.41)％,(6.91 ±1.31)％,(6.56±1.62)％](P＜0.05).Significant difference could not be found in neither the IMT nor the FMI between the VSI control group and health group in 4 period respectively,P ＞ 0.05.Conclusion Children after successful coarctation repair have abnomal structural and functional properties of the aorta above the place of coarctation even their blood pressure at rest is normal.These results confirm that the alterations in mechanical properties of carotid arteries as well as the generalized endothelial dysfunction in children with coarctation of the aorta are persistent,which can not be prevented or reversed by surgical repair,and which may partly explain the high incidence of cardiovascular disease observed in their adulthood and reduced life expectancy,furtherly supporting the claim that coartation of the aorta is a systemic vascular disorder which needs long-term follow-up of vascular function.

Objective To evaluate the endothelium-dependent vasodilation in children after repair for coarctation of aota (CoA). Methods A group of 20 children having undergone CoA repair between January 2010 and October 2010 in Guangzhou Women and Children′s Medical Center were include in the study , including 12 infants aged less than 6 months and 8 ones aged more than 6 months. Another 20 healthy children were enrolled during the same period as controls. All the subjects underwent monitoring of resting blood pressure and flow-mediated dilation (FMD) of the brachial artery in 4-year follow-up. Results There were no resting hypertension in all subjects , but FMD in the CoA group was higher than in the control group and so it was with the early surgery group and non early surgery group. Conclusion The surgical repair for coarctation of aorta could not cure the vascular function impairment satisfactorily , neither is the early surgery effective in alleviating the injuries in vascular endothelia.

OBJECTIVETo determine the levels of urinary soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) in patients with lupus nephritis (LN), and explore their correlation with renal disease activity.

METHODSUrine samples were collected from 92 renal biopsy-proven LN patients and 20 healthy controls. Renal disease activity was determined according to the ISN/RPS 2003 Revised Classification of Lupus Nephritis. The urine levels of sICAM-1 and VCAM-1 were detected by enzyme-linked immunosorbent assay, and the expressions of intrarenal ICAM-1 and VCAM-1 were evaluated by immunohistochemisty staining.

RESULTSUrinary sICAM-1 and VCAM-1 levels were elevated in LN patients compared with the controls. Significantly higher levels of urinary sICAM-1 and VCAM-1 were found in patients with active LN, who had also significantly increased intrarenal expressions of ICAM-1 and VCAM-1 compared with patients in remission. A strong positive correlation was noted between intrarenal expression and urine levels of ICAM-1 and VCAM-1. The receiver-operating characteristic (ROC) curve of urine sICAM-1 showed tan area under ROC curve of 0.874 for all participants in the test. A cutoff of 1095.00 pg/mg creatinine yielded a good sensitivity (0.945) and specificity (0.789). The ROC curve of urine VCAM-1 showed an area under ROC of 0.882 for all the participants, and a cutoff of 898.11 pg/mg creatinine yielded a good sensitivity (0.982) and specificity (0.667).

CONCLUSIONUrine sICAM-1 and VCAM-1 levels are positively correlated with their intrarenal expressions and reflect the activity of the nephritis, and therefore they may serve as potential biomarkers for early diagnosis of active LN.

Objective:To explore the influencing factors of seasonal influenza among pregnant woman in Suzhou from 2015 to 2018.Methods:Based on the data of the influenza follow-up cohort of pregnant women in Suzhou from 2015 to 2018, the basic and clinical characteristics of the cohort were described, and the influencing factors of laboratory-confirmed influenza cases in pregnant women were analyzed by unconditional logistic regression.Results:A total of 19 006 pregnant women were recruited, in whom 479 cases of influenza were laboratory confirmed. Influenza A (H3N2) (42.8%) was the main sub-type. In pregnant women with exposure risk in influenza season, unconditional univariate logistic analysis showed that pregnant women or their husbands had registered permanent residence in Suzhou, pregnant women worked as childminder or nanny, had more than 2 permanent residents in the family except themselves, had medical insurance in Suzhou, had fertility insurance in Suzhou, were in the third trimester at the time of enrollment, had cough in the past month, were pregnant for the first time, had children, before and after pregnancy, spent more time outdoors than before, wore masks more often than before and had changed the frequency of gathering were all related to influenza virus infection in pregnant women. Among them, the first pregnancy, increasing the time of outdoor activity, increasing the frequency of wearing masks, and changing the frequency of gathering were important protective factors. Unconditional multivariate logistic regression analysis showed that the number of permanent residents at home was >2 (a OR=1.24, 95% CI: 1.01-1.52) and being in the third trimester, (a OR=1.56, 95% CI: 1.26-1.91) were the risk factors for maternal infection with influenza virus. Conclusion:Pregnant women with a large number of permanent residents and late pregnancy should pay attention to preventing seasonal influenza.

Objective:To understand the current knowledge, attitude, and practice (KAP) on influenza and influenza vaccine among pregnant women in Suzhou and to analyze its influencing factors to provide technical support data for public health strategies for promoting influenza vaccination in pregnant women.Methods:A questionnaire was designed, and a stratified sampling method was used to conduct a face-to-face survey among pregnant women at different stages of pregnancy who received antenatal examinations at different levels of medical institutions in Suzhou, Jiangsu Province, in 2023. KAP status and influencing factors were analyzed by χ2 test and logistic regression analysis. Results:A total of 2 195 valid questionnaires were collected in this survey. The M( Q1, Q3) of knowledge about influenza and influenza vaccine among pregnant women in Suzhou was 7.60 (5.23, 9.80) points, and the score range was 0.20-14.71 points, the passing rate was 34.12%, the awareness rate of influenza vaccine was 57.45%, and the vaccination rate of influenza vaccine was 1.91% within one year before the survey. The willingness to receive influenza vaccine during pregnancy was only 3.57%. Multivariate analysis of influenza and influenza vaccine-related knowledge scores showed that the passing rate was positively correlated with education level and gestational age. In contrast, family income was negatively correlated with living in rural areas, working as migrant workers, and having no medical insurance. Multivariate analysis of vaccination intention showed that decreased effectiveness of influenza vaccine and increased adverse reactions decreased vaccination intention during pregnancy. Conclusions:The pregnant women in Suzhou pay more attention to influenza, and vaccination rates and intentions are generally low. Pregnant women with early and second trimester of pregnancy, low education, living in rural areas, working as migrant workers, and not purchasing medical insurance are the key groups to popularize the knowledge about influenza and influenza vaccine.

PURPOSE: Studies suggest that regular use of metformin may decrease cancer mortality. We investigated the association between diabetes medication use and cancer survival. MATERIALS AND METHODS: The current study includes 633 breast, 890 colorectal, 824 lung, and 543 gastric cancer cases identified from participants of two population-based cohort studies in Shanghai. Information on diabetes medication use was obtained by linking to electronic medical records. The associations between diabetes medication use (metformin, sulfonylureas, and insulin) and overall and cancer-specific survival were evaluated using time-dependent Cox proportional hazards models. RESULTS: After adjustment for clinical characteristics and treatment factors, use of metformin was associated with better overall survival among colorectal cancer patients (hazards ratio [HR], 0.55; 95% confidence interval [CI], 0.34 to 0.88) and for all four types of cancer combined (HR, 0.75; 95% CI, 0.57 to 0.98). Ever use of insulin was associated with worse survival for all cancer types combined (HR, 1.89; 95% CI, 1.57 to 2.29) and for the four cancer types individually. Similar associations were seen for diabetic patients. Sulfonylureas use was associated with worse overall survival for breast or gastric cancer (HR, 2.87; 95% CI, 1.22 to 6.80 and HR, 2.05; 95% CI, 1.09 to 3.84, respectively) among diabetic patients. Similar association patterns were observed between diabetes medication use and cancer-specific survival. CONCLUSION: Metformin was associated with improved survival among colorectal cancer cases, while insulin use was associated with worse survival among patients of four major cancers. Further investigation on the topic is needed given the potential translational impact of these findings.
