BACKGROUND:Corneal lymphangiogenesis is beneficial to the transport of corneal antigenic materials, and accelerates the process of antigen presentation, thereby playing an important role in corneal immunity. However, due to the paral el outgrowth of corneal blood and lymphatic vessels in transplanted corneas, it is often difficult to accurately evaluate the role of corneal lymphatic vessels in allograft rejection. OBJECTIVE:To explore the development of corneal lymphangiogenesis and angiogenesis in transplanted rat corneas after the blockade of vascular endothelial growth factor C (VEGF-C). METHODS:130 rats used to establish corneal al ogenic transplantation models were equally randomized into two groups:the anti-VEGF-C group and the control group. VEGF-C was blocked in the anti-VEGF-C group by intraperitoneal injection of neutralizing monoclonal anti-VEGF-C antibody every other day for 2 consecutive weeks. Meanwhile, rats in control groups received intraperitoneal injections of saline. Corneal angiogenesis and lymphangiogenesis were characterized using whole mount immunofluorescence, and the immune rejection of the grafts was evaluated by scoring the rejection index (RI). In addition, the expression of VEGF-C was examined by real-time PCR. The relationship of corneal lymphangiogenesis and angiogenesis to RI in transplanted corneas was also characterized. RESULTS AND CONCLUSION:VEGF-C expression was markedly downregulated after VEGF-C blockade. Corneal lymphangiogenesis developed in parallel with corneal angiogenesis in the control group. While there was a mild reduction in blood vessel area (BVA) and a significant decrease in lymphatic vessel area (LVA) in the anti-VEGF-C group (P<0.05). In addition, RI was positively correlated with BVA (P<0.05) and LVA (P<0.05) in the control group. However, although RI was significantly correlated with BVA (P<0.05) in the anti-VEGF-C group, the correlation between RI and LVA was not statistically significant (P>0.05). the graft survival time in the anti-VEGF-C group was significantly increased compared with that in the control group (P<0.05). Our results show that the outgrowth of lymphatic vessels is separated from that of blood vessels in transplanted corneas by blocking VEGF-C. The blockade of VEGF-C has a significant role in preventing corneal lymphangiogenesis in corneal beds, which results in higher al ograft survival rates.

Objective To evaluate the clinical significance of improving the goal attainment rate by management of timely feedback of hypertension patients, which is carried out by using existing communication network. Methods Totally 423 hypertension patients who were hospitalized for treatment in Daping Hospital from Jan. 2012 to Jan 2013, the random numbers table was used to randomize the patients into 2 groups: control group (212 cases) and experiment group (211cases), the conventional treatment was used in control group. Besides the conventional treatment measures, the modern way of communication and network information platform was used by patients who timely feed back the blood pressure changing, and implement the cognitive treatment of hypertension at the same time in the experiment group. The Chi square test was used to compare the patient's medication compliance, the attainment rate and so on , the t test was used to compare the blood pressure in two groups of patients after the intervention. Results At the end of the intervention, the difference of heavy salt diet (reduced to 16.59%), regularly drinking (reduced to 13.74%), heavy sugar diet (reduced to 10.43%), abnormal blood lipid (reduced to 19.91%), smoking (reduced to 27.96%), the number of people who have a stable mood (up to 91.47%), body mass index (reduced to 29.38%) and exercise at ordinary times (reduced to 36.02%) were statistically significant (P< 0.05). Hypertension patients compliance increased significantly, of which the medical behavior of 84.83%, compared with 13.21%in the control group, there was statistically significant difference (χ 2=8.54,P< 0.05). And the awareness, treatment, success rate of blood pressure control were 94.79%, 84.36%, 82.94% in experimental group and 50.94%, 40.09%, 27.83% in control group, and the differences were statistically significant (P<0.05). Conclusion Use of the existing information interaction platform in order to strengthen the management of the blood pressure of hypertension patients and related cognitive behavioral intervention, the control of risk factors and treatment compliance have improved significantly. The remote interaction platform used to patients with hypertension management improve the attainment rate of high blood pressure.

AIM: To evaluate the effects induced by topical antiglaucomatous drugs, Travoprost eyedrops on tear film.

Objective To investigate the characteristics of maternal thyroid function of pregnant women with negative thyroid antibody in high water iodine area. Methods The investigation sites were selected,which were the Hospital for Women and Children of Jinghai county in the high water iodine area(drinking iodine > 200 μg/L) and the Hospital for Women and Children of Heping district in Tianjin in the adaptive iodine area (drinking iodine < 10μg/L,popularization rate of iodized salt > 90％,residents urinary iodine > 200μg/L). In the maternal and child hospitals,50 pregnant women of each stage from obstetric clinics in first,second,third term of pregnancy were selected,the blood samples were collected and the thyroid function were measured with chemiluminescence. Water,salt and diurnal optional urine samples were measured for iodine concentration. Iodine levels of urine,water,salt were determined respectively by As-Ce catalysis spoctrophotometry method,quantitative determining kit which use time-recorded determination by catalytic effect on the As-Ce reaction and sodium hyposulfite titration method. Results ①In pregnant women with negative thyroid antibody,serum TT_4,TT_3,FT_4 in first term of pregnaney and TT_4,TT_3 in second term of pregnancy were significantly lower in high water iodine area than low water iodine area(111.97 nmol/L vs 140.46 nmoL/L,Z = 3.56,P < 0.01 ; 1.86 nmol/L vs 2.26 nmol/L,Z = 2.35, P < 0.05; 14.13 pmol/L vs 16.32 pmol/L,Z = 5.14,P < 0.01,and 11.98 pmol/L vs 14.30 pmol/L,Z = 5.75,P < 0.01 ; 4.04 pmol/L vs 4.32 pmol/L,Z = 2.76,P < 0.01),while TT_3 and TSH in third term of pregnancy were significantly higher(2.88 nmoL/L vs 2.70 nmol/L,Z=-2.27,P< 0.05; 2.37 mU/L vs 1.75 mU/L,Z =-2.70, P < 0.01).②Concentration of water iodine and urine iodine were higher(205.57μg/L vs 8.26 μg/L,Z =-14.71,P < 0.01 ; 305.91 g/L vs 191.86 g/L,Z =-5.30,P < 0.01),while salt iodine was lower(26.5 mg/kg vs 31.7 mg/kg,Z =-5.86,P < 0.01) in high water iodine area. ③Among 290 selected healthy pregnant women without medical history of thyroid diseases,there was no significant difference in positive rate of thyroid antibody in each term of pregnancy between high water iodine area and low water iodine area(10.20％ vs 10.64％ ; 14％ vs 9.52％ ; 4％ vs 7.69％ ; all P > 0.05). Conclusions The thyroid function of pregnant women with negative thyroid antibody in high water iodine area is different from pregnant women in low water iodine area with universal salt iodization. Enhanced monitoring on thyroid function of pregnant women in high water iodine area should be performed,especially in first and second trimester.

OBJECTIVETo investigate the clinical features of Crohn disease according to the Montreal classification.

METHODSClinical data of 43 surgical patients with Crohn disease (surgical group) and 125 non-surgical patients with Crohn disease (non-surgical group) were retrospectively analyzed and compared between two groups. The Montreal classification was used.

RESULTSIn the surgical group, 28 patients (65.1%) were A2, 14 (32.6%) were A3 and only one was A1, which was not significantly different as compared to the non-surgery group. The proportions of L1, L2, L3, and L4 subtype in the surgical group were 41.9%, 25.6%, 30.2%, and 2.3%, respectively, which was not significantly different as compared to that in the non-surgery group. In the surgical group,B1 disease was found in 1 case (2.3%), B2 in 26 cases (60.5%), and B3 in 16 cases (37.2%), while in the non-surgical group, B1 was found in 79 cases (63.2%), B2 in 44 cases (35.2%) and B3 in 2 cases (1.6%). Differences were significant between two groups in disease behavior (P=0.001, P=0.004, P=0.001).

CONCLUSIONSMost surgical patients of Crohn disease are A2. L1 and L3 are the main lesion location. As disease behavior, B2 and B3 are the main reasons for operation.

OBJECTIVETo analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China.

METHODSA cross-sectional, population-based survey of prevalence of asthma was conducted in children aged from 0 to 14 years in 3 major cities of China (Beijing, Chongqing, and Guangzhou) with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase III questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question "Has your child ever been diagnosed as asthma by a doctor" were recognized as victims of asthma.

RESULTSThe prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria (χ²=3.938, P=0.047; χ²=73.506, P≤0.001; χ²=11.956, P=0.001, in each city). Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children, followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females.

CONCLUSIONThe prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.
