Objective To investigate the relationship between leukocyte counts and coronary artery stenosis as well as try to find the possible cause of coronary heart disease. Methods All the 220 patients underwent coronary angiography and leukocyte counts. The Gensini scoring system was used to determine the results of the coronary angiography. All patients were allocated into three groups according to the Gensini score. 74 cases with 0-3.00 score were classified into group CHD1 while 73 cases with 3.01-32.67 score were classified into group CHD2 and 73 cases with 32.68-180.00 score into group CHD3. The distribution of leukocyte counts in the three groups underwent analysis of variance and the relationship between leukocyte counts and the Gensini score was further investigated by means of multiple linear regression analysis. [WT5”HZ]Results The analysis of one way variance showed that neutrophil, monocyte and leukocyte counts were associated with the Gensini score. Multiple linear regression analysis adjusted for many risk factors for coronary heart disease showed that neutrophil counts had independent association with the Gensini score. Conclusion Neutrophil counts were independently associated with coronary artery stenosis.

Objective To explore the clinical application and outlook of anterior segment observation with Stratus optical coherence tomography(Stratus OCT).Design Prospective case series.Participants 56 eyes in 38 patients with primary angle closure glaucoma (PACG).Methods Morphological changes of anterior chamber angle (ACA) were observed with Stratus OCT before and 4 weeks after laser iridectomy.Opening status of ACA were described and measured with Photoshop software.Main Outcome Measures Opening degree of ACA and ratio of anterior chamber depth to thickness of cornea.Results To a great deal of extent,Stratus OCT could be used to observe the appearance of ACA. Clear images of ACA could be acquired.The ACA before laser was (15.67?5.33) degree and significantly reopened to(26.56?8.17) degree after laser iridectomy (P=0.000).The ratio of anterior chamber depth to thickness of cornea was also changed from (0.39?0.13) pre-treatment to (0.89?0.32) pest-treatment(P=0.000).Conclusions Stratus OCT could be applied to observe the changes of opening degree of ACA easily.The standard of quantization should be consummated in the future.

BACKGROUND:Previously, serious thoracolumbar burst fractures with spinal cord injury were mainly treated by anterior surgery. The superiority of conventional posterior repair lies in strong reduction and fixation effects. However, it is difficult to fuly decompression. The anterior and central cylinders of the injured vertebra cannot receive good reconstruction. Loss of correction and internal fixation failure always appear. It remains controversial which repair method is more ideal. OBJECTIVE:To comparatively analyze the effect of posterior and anterior approaches with subtotal vertebrectomy, decompression, reconstruction of spine, and internal fixation for patients with thoracolumbar burst fractures. METHODS: The data of 42 patients with thoracolumbar burst fracture treated by anterior and posterior approaches with subtotal vertebrectomy, decompression, and reconstruction of spine from May 2006 to December 2012 was retrospectively analyzed. They were divided into two groups according to the surgical procedures: anterior approach group (n=23) and posterior approach group (n=19). They were folowed up for at least 24 months. Repair results and imaging results were compared in patients of both groups. RESULTS AND CONCLUSION:None patients in the two groups affected fixator loosing or breakage, and obtained good bone fusion. The intraoperative blood loss was more and operative time was longer in the anterior approach group than in the posterior approach group, showing significant difference (P < 0.05). The pulmonary function was significantly better in the posterior approach group than in the anterior approach group (P < 0.05). Visual Analog Scale score, Japanese Orthopaedic Association score for back pain and Frankel classification were significantly improved during final folow-up compared with pre-treatment in both groups, but no significant difference was found between groups (P > 0.05). No significant difference in the anterior vertebral height and kyphosis Cobb angle was detected before treatment, at 1 week after treatment and during final folow-up (P > 0.05). The incidence of postoperative complications was significantly higher in the anterior approach group than in the posterior approach group (P < 0.05). These findings confirm that subtotal vertebrectomy through anterior approach and posterior approach can effectively repair thoracolumbar burst fractures. However, the complications of posterior approach are less, and posterior approach has few impacts on the pulmonary function, is safe, and has good biocompatibility with the host.

Background Tumstatin is the most active endogenous angiogenesis inhibitor,which has a marked inhibitory effect on pathological neovascularization,and Tum5 is an angiogenesis inhibitors fragment of fulllength tumstatin.Objective This study was to investigate the effects of adenovirus-mediated overexpression of recombinant Tum5 gene on the proliferation,migration and tube formation of human umbilical vein endothelial cells (HUVECs) in physiological status.Methods The empty adenoviral vector expressing green fluorescent protein (rAd-GFP) and the viral vector expressing recombinant Tum5 gene were constructed.The HUVECs cultured in RPMI1640 medium were divided into normal control group,empty vector group (rAd-GFP group) and Tum5 gene infection group (rAd-GFP-Tum5 group).The rAd-GFP and rAd-GFP-Tum5 adenoviral particles at the density of 1 × 1010/ml were added into the medium to infect the cells for 48 hours.The proliferation of the cells was assayed at 24,48 and 72 hours by cell counting kit-8 (CCK-8) to evaluate the proliferative rate;the migration number of the cells was detected at 48 hours after infection by Transwell chamber;the tube formation number of the cells were detected by Matrigel method.The concentration of vascular endothelial growth factor (VEGF) in cell supernatants was assayed by ELISA at 24,48,and 72 hours following adenoviral infection.Results The cultured cells showed green fluorescence in the rAd-GFP group and rAd-GFP-Tum5 group under the inverted fluorescence microscope,and the infection efficiency of rAd-GFP and rAd-GFP-Tum5 was 55.13％ and 50.31％,respectively.No significant difference was found in cell proliferative rate among normal control group,rAd-GFP group and rAd-GFP-Tum5 group both at 24 and 48 hours after infection (both at P＞0.05),and the cell proliferative rate was significantly lower in the rAd-GFP-Tum5 group than that in the normal control group and rAd-GFP group at 72 hours after infection (both at P＜0.01).The migration number of the cells at 48 hours after infection was 2 260.25-±930.44,2 370.00±441.06 and 723.75± 363.80 in the normal control group,rAd-GFP group and rAd-GFP-Tum5 group,showing a significant difference among the groups (F =8.524,P =0.008),and the migrated cells were evidently decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group and the normal control group (both at P＜ 0.01).The tube number at 48 hours after infection was 95.67±5.86,88.00±4.58 and 20.67±3.51 in the normal control group,rAd-GFP group and rAdGFP-Tum5 group,showing a significant difference among the groups (F=226.498,P＜0.01),and the tube number in the rAd-GFP-Tum5 group was significantly reduced in comparison with the normal control group and rAd-GFP group (both at P＜ 0.01).The considerably differences in VEGF concentration in the cell supernatants were found in different groups and various time points (Fgroup =73.260,P＜0.01;Ftime =73.477,P＜0.01),and VEGF concentration in the cell supernatants was significantly decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group at both 48 hours and 72 hours (both at P＜0.01).Conclusions The overexpression of the recombinant Tum5 can inhibit the proliferation,migration and tube formation of the HUVECs in physiological status,which may be associated with Tum-5-mediated down-regulation of VEGF protein in the cell supernatant.

Objective To evaluate the status of iodine deficiency disorders(IDD) in Huai'an City in 2011 and to provide a scientific basis for adopting target prevention strategies timely and adjusting the intervention policy scientifically.Methods According to The National Project of Surveillance on IDD,probability sampling method (PPS) was used to select 30 counties in Huai'an City,and one primary school was selected randomly from each county,then 40 children aged 8 to 10 were randomly selected in each school.Children's thyroids were examined by palpation and the iodine in salt samples collected in their home was tested by direct titration.At the same time,urine samples from 12 children of the 40 selected children were collected and urinary iodine was tested by As(Ⅲ)-Ce4+ catalytic spectrophotometry.Questionnaire survey of IDD was conducted among 30 students of grade 5 and 5 housewives around that school.Results A total of 1200 children aged 8 to 10 were examined,and the goiter rate was 1.3％(15/1200).All the goiters were level Ⅰ.The goiters of each age group was 0.8％(3/390),1.8％(7/390) and 1.3％(5/420),respectively.The 360 urine samples were collected from children aged 8-10,and the median of urinary iodine was 171.5 μg/L with the proportions of ＜ 20 μg/L,＜ 50 μg/L and ＜ 100 μg/L were 0(0/360),1.1％ (4/360) and 5.6％ (20/360),respectively.A total of 1200 salt samples were tested in children's family.The coverage rate of iodized salt was 99.4％ (1193/1200) and the qualified rate of iodized salt was 97.7％ (1165/1193).The consuming rate of qualified iodized salt was 97.1％(1165/1200),and non iodized salt rate was 0.6％(7/1200).The knowledge rates of IDD were 82.7％ (2234/2700) and 69.8％ (314/450) in 900 students and 150 housewives,respectively.Conclusions In Huai'an City,except the knowledge rate of IDD,the goiter rate and urinary iodine of children aged 8-10,iodized salt consumption maintain at the stage of the target level.In addition to strengthen the monitoring of iodized salt and to supply qualified iodized salt,it should also increase the focus on health education propaganda in the future.

Objective To study the changes of umbilical blood lactate,pH, blood sugar(BS),bilirubin, electrolyte, osmotic pressure (OP) in the newboms with fetal distress.Methods Thirty-five newborns with fetal distress (distress group) and 40 healthy new-borns (control group) were studied. Distress group were divided into distress group Ⅰ and distress group Ⅱ respectively, based on without or with neonatal asphyxia. Concentration of umbilical blood lactate was determined with enzyme method, pH, BS,serum total bilirubin (BIL), serum electrolyte (Na+ ,K+ ,Ca2+ ) and OP were analyzed respectively. Results 1. The difference of incidence of newborn asphyxia between distress groups (29.03%) and control group (2.50%) was statistically significant. 2. Compared with the controls and distress group Ⅰ, the umbilical blood lactate concentration significantly increased in distress group Ⅱ (P 0.05).The incidence of hyperglycemia was significantly elevated in distress groups than that in the control group. 4. Lactate concentration in distress I and distress fl group showed negative correlation with pH. Conclusion The concentration of umbilical blood lactate can provide the proof for diagnosis and prognosis of fetal distress.
