Objective To analyze the relationships between body mass index (BMI), blood pressure and the cerebral vascular function in middle-aged population that underwent health checkup. Methods Participants from health management centers of Renmin Hospital of Hubei province, the Second Hospital Affiliated to Nanhua University, Hospital of Shandong Electric Power and Chinese People's Liberation Army No. 180 Hospital aged 45 to 64 years were selected from health checkup population by cluster sampling. Levels of height, weight and blood pressure as well as the cerebral hemodynamics were checked. Subjects were grouped according to age, BMI, systolic and diastolic blood pressure. The differences and distribution of cerebrovascular function scores (CVFS) between groups were compared and described. Moreover, the risk of stroke in the population was evaluated. Results Of the 17 258 individuals who met inclusion criteria, the abnormal rate (the score below 75 points) of CVFS was 20.9 percent. The CVFS in normal, overweight and obese groups were 91.0±15.4, 83.3±21.3, 70.3±26.5 and differences in all age groups were statistically significant (P<0.01). The CVFS in systolic blood pressure<120,120-139, 140-159,≥160 mmHg (1 mmHg=0.133 kPa) groups were 93.9±12.9, 86.5±18.9, 72.1±23.5, 56.2±25.7 and differences in all age groups were statistically significant (P<0.01). CVFS in normal diastolic pressure<80, 80-89, 90-99,≥100 mmHg groups were 91.0±16.1, 85.5±20.2, 75.4±23.6, 62.7±25.0 and the differences among all age groups were statistically significant (P<0.01). Conclusions The abnormal rate of cerebrovascular function integral and high risk stroke individuals in middle-aged health checkup people was approximately 21 percent. The overweight, obese and the high level of systolic and diastolic pressure may induce the injury of cerebrovascular function and the severity will increase with the level of BMI and blood pressure.

Objective To investigate the effect of dietary fiber on carbohydrate metabolism of healthy volunteers after the intake of corn starch meal. Methods Totally 12 healthy volunteers aged (25. 8 ± 5. 3) years were enrolled in this study, and they were equally randomly divided into two groups (group A and group B). This was an open, randomized, cross-over, and two-period study, and each period lasted for one day. In period 1, the subjects in group A received fiber-free corn starch and group B received high-fiber corn starch (containing 16 g dietary fiber). In period 2, the two groups are crossed. There was a one-week wash-out time between the two study days. On the study day, breath samples of fasting and 0. 5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0,7. 0, 8. 0 hours post meal were collected to measure13 CO2. Results The delta over baseline at 0. 5, 1.5, 2. 0,2. 5, 3. 0, 4. 0 hour after test meal in fiber free group and in high fiber group were 0. 79, 2. 03, 2. 57, 2. 86,3. 02, 3. 18 and 0. 16, 1. 33, 1.77, 2. 10, 2. 34, 2.42, respectively (the P value was 0. 014, 0. 014, 0. 011,0.018, 0. 036, and 0.020, respectively). Peak concentration of delta over baseline of fiber free group and high fiber group was 3.18 and 2. 56 respectively, there was no significant difference between two groups (P > 0. 05) ,peak time of the group at 4. 0 hour and 3. 5 hour respectively, showed significant difference (P = 0. 032). The cumulative percentage dose recovered 0. 5-6. 0 hours after test meal in fiber-free group and in high-fiber group were 0.41, 1.46, 3.15, 5.50, 8.28, 11.30, 14.42, 17. 62, 23. 65, 28. 78 and 0. 09, 0. 55, 1.61, 3.22,5.23,7.53, 10.09, 12.68, 17.60, 22.27 respectively (the P value was 0.014, 0.018, 0.018, 0.014, 0.013,0.014, 0.018, 0.020, 0.025, and 0.044, respectively). However, there was no significant difference 6.0 hours after meal (P > 0. 05 ). Conclusion The dietary fiber used in this study can delay the absorption of carbohydrate 6. 0 hours within intake without influencing its total absorption amount.

Objective To evaluate atrial septal defect (ASD) occlusion employing a small right anterior thoracotomy approach. Methods A total of 21 patients with ASD underwent general anesthesia and 2 -3 cm incision was made in the fourth right intercostal space. Utilizing transesophageal or transthoracic echocardiography, the occluder was released using a monotube unit. Results All patients were occluded successfully. No patient required open surgery utilizing extracorporeal circulation. There were no major complications and no evidence of residual atrial shunt. Conclusion ASD occlusion via a minimal surgical incision is safe, less invasive, and has excellent outcomes.

Background Recently,the number of randomized controlled trials on ophthalmic diseases that published in international journals from mainland China has increased gradually.There is no systematic summary in this field.Objective To systematically search and analyze the distribution of ophthalmic diseases related randomized controlled trials (RCT) published in SCI journals from mainland China up to November,2012.Methods The search was performed on Pubmed using “Ophthalmology”,“Eye” and all of their inferior subjective terms,with type of literature being limited as randomized controlled trial,and country as China.All retrieved papers were screened,data extracted and analyzed.Results There were 68 ophthalmic diseases related RCT papers published from mainland China since 1989.After 2005,the number of RCT papers from mainland China increased quickly with 7 in 2006,11 in 2009,and 15 in 2011.The 68 RCT papers were focused on cataract,optometry,glaucoma,corneal and conjunctival diseases,ophthalmic immune and pharmacology,and fundus diseases.The RCT papers were published in a total of 35 SCI journals including most kinds of ophthalmic journals such as Ophthalmology,IOVS and a few journals on other specialty.The journal Clin Experiment Ophthalmol had the maximum RCT papers from China (8 papers).The 68 RCT papers came from 26 departments in mainland China,mainly from the hospitals affiliated to medical university in Guangzhou,Beijing,Shanghai,Wenzhou and Hangzhou.Conclusions The number of ophthalmic diseases related RCT papers published in SCI journals from mainland China increased continuously.The papers were mainly focused on cataract,optomctry and glaucoma.The number of these papers,however,was still small and imbalance between districts existed.

Objective To evaluated the effect of hyperbaric oxygenation therapy(HBO)on the RhoA ex- pression and nerve function after transient focal cerebral ischemia in a rat model of middle cerebral artery occlusion. Methods One hundred and twenty-six healthy Sprague-Dawley rats were used and randomly divided into a sham op- eration group(shame group,n=42),a treatment group(n=42),and a control group(n=42).The animal model of middle cerebral artery occlusion(MCAO)was established by using the Zea-Longa method with the animals in the treatment and the control groups,and sham operation was performed with those in the sham group.HBO was applied to the animals in the treatment group.The RhoA protein expression was observed by using immunohistochemistry technique,and the neurological function was evaluated by Bederson's scale at different time points after MCAO.Re- sults(1)Weakly positive expression of RhoA could be located in bilateral cortex and the basal ganglia in the sham group.The expression of RhoA in the treatment group and control group was increased as early as 6 hours after MCAO when compared with that of the sham group,and peaked at 48 h after MCAO and decreased after then,but was still higher than that of the shame group at 7th day to 14th day after MCAO.It was also found that the expression of RhoA of the treatment group was significantly lower than that of the control group(P

Objective To discuss the role of assistance of intraoperative uitrasonography in ret-roperitoneal laparoscopic nephron-sparing surgery for renal tumors. Methods The intraoperative laparoscopic ultrasonography was applied in retroperitoneal nephron-sparing surgery for 20 patients, of whom 11 were men and 9 were women. The average age was 53(range 33 to 73) years. There were 12 patients with renal cell carcinoma and the mean tumor size was 2.9(range 1.4 to 4.6)cm in diame-ter. All of them were staged as T1 N0 M0. Seven patients had angiomyolipoma and the mean tumor size was 4.5(range 1.8 to 8.0)cm in diameter and 1 patient had a 3.1 cm oncocytoma in diameter. The ul-trasonography was used to locate the tumor, observe the bloodstream and detect whether there were small satellite tumors. The surgical time, time of renal artery occlusion and operative effect were ob-served. Results Laparoscopic surgery was successful in all cases without conversion to open surger-y. Mean operative time was 115 (range 85 to 270) min, mean time of renal artery occlusion was 28 (range 22 to 50) min. During the mean followup of 16(range 4 to 30) months, no patients with renal cell carcinoma had local or port site recurrence or metastatic disease. Conclusion In retroperitoneal laparoscopic nephron-sparing surgery, the intraoperative uhrasonography is helpful to locate the tumor in the surgery, to estimate whether the renal artery is occluded completely and to excise the tumor pre-cisely.
