· AIM: To summarize the clinical features of Chinese primary congenital glaucoma and to investigate the discrepancies of the clinical features between the Chinese and Indian patients.congenital glaucoma patients were reviewed. The clinical features were summarized as several quantifiable clinical parameters and the severity of the disease was evaluated. Both the quantified clinical features and severity were statistically compared with those of the Indian patients, which were cited from the previous published articles.included in the study. In Chinese patients, sex ratio (male to female )was about 2:1, family history was presented in 3 patients (7.5%) and consanguinity was found in one patient (2.5%). The main symptoms and signs observed in Chinese patients spanned a wide spectrum of manifestations. The most frequent signs noted on the initial examination were enlarged eyeball (42.5%) and decreased visual acuity (35.0%). Compared with Indian patients, Chinese patients had a later onset, a delayed diagnosis, more severe corneal changes and more severe optic nerve damages (P＜0.01). The combined tabeculectomy and trabeculotomy operation was preferred by both Chinese and Indian doctors whereas a higher proportion of Indian patients received the combined operation (P＜0.01). The proportions of the severity grade were different between Chinese and Indian patients. Most Chinese patients were in the severe grade while most Indian patients were in the very severe grade (P＜0.01).patients were sporadic and non-consanguineous.Compared with Indian patients, Chinese patients had a relative later onset, a delayed diagnosis and treatment.More attempts are needed in Chinese PCG prevention and treatment.

AlM:To investigate the expression transforming growth factor-β1 (TGF-β1) and heat shock protein 47 (HSP-47), in pterygium and normal conjunctiva tissues, in order to study the roles of these cytokines played in the pathogenesis in human pterygium.
METHODS:The expression difference of TGF-β1, HSP-47 between human pterygium and normal conjunctive tissues were compared by immuno - histochemistry technique.
RESULTS:The positive expression of TGF-β1, HSP-47 was stronger than in normal conjunctive tissues ( P <0. 05), the TGF-β1 expressed in all layers of pterygium, especially in the squamous epithelium, in the inflammation cells and vascular endothelial cells also expressed. The HSP-47 showed higher expressed in the lamina propria layer of pterygium, and weakly expressed in epithelial layer, no obvious expression in normal conjunctive tissues.
CONCLUSlON:Over-expression of TGF-β1 and HSP-47 in pterygium compared to the normal conjunctiva tissues may play a critical role during the occurrence, development and invasion of the pterygium.

Objective To study the mechanism, clinical characteristics, diagnosis and treatments of orbital fracture-induced exophthalmos after craniocerebral injury. Methods We retrospectively analyzed the data of 13 patients with orbital fracture-induced exophthalmos after head injury: their causes of injury, clinical situations, types of fracture, operative treatments and surgical outcomes. Spiral CT thin slice scan and three-dimensional reconstruction were performed on the orbit before any treatment, and then, orbital fractures were repaired by corresponding surgical approaches according to the position of fractures and head injury. The effect of operation was evaluated by spiral CT and follow up was performed. Results The patients obviously manifested as having craniocerebral injury and 14 eyeballs in 13 patients had exophthalmos. The average preoperative degree of protrusion was (2.94±0.47) mm.The axial spiral CT together with the reconstructive picture presented the pre- and pro-operative orbital fractures clearly. Orbital fracture positions were situated at superior and medial wall of the orbit. All operations were succeed without death or severe disability. Conclusion The diversify of intracranial pressure is the main reason of orbital fractures which shrinks towards the inter orbit to its volume and induces exophthalmos after craniocerebral injury. The spiral CT examination has vital significance in the diagnosis and treatment of orbital fracture-induced exophthalmos and the patients can obtain good outcome by early surgery.

OBJECTIVETo access the prevalence rates of pre-hypertensive patients at different stages and its associated risk factors among adults of Zhejiang province.

METHODSStudy subjects were selected among local residents aged ≥ 18 years from 15 counties by multi stage stratified cluster random sampling method, from July to November, 2010. Each participant was required to complete questionnaire, physical examination and testing for overnight fasting blood specimen.

RESULTS17 437 residents were surveyed including 8169 males and 9268 females. The overall prevalence of prehypertension was 34.39%. The prevalence of pre-hypertension appeared to be higher in males (38.57%) than in females (30.70%) (χ(2) = 119.36, P < 0.0001). The prevalence of pre-hypertension decreased with the increase of age in males who were above 25 year olds (χ(2) = 76.94, P < 0.0001) and in females who were above 45 year olds (χ(2) = 114.66, P < 0.0001). The prevalence of pre-hypertension appeared to be higher in the rural (35.60%) than in the urban (32.39%) areas (χ(2) = 18.69, P < 0.0001). Data from multivariable logistic regression showed that factors as being male, aged older than 35 years of age, with waist circumference as ≥ 85 cm for men and ≥ 80 cm for women, body mass index ≥ 25.0 kg/m(2) and triglyceride ≥ 1.7 mmol/L were risk factors of pre-hypertension while having had higher education was a protective factor.

CONCLUSIONPre-hypertension was prevalent among adults residents in Zhejiang province. Factors as overweight, obesity, dyslipidemia appeared to be major risk factors for pre-hypertension.

OBJECTIVETo explore the association between dyslipidemia and different subtypes of hypertension among Zhejiang population.

METHODSFrom June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7571 families from fifteen counties in Zhejiang by four stage stratified-random sampling method. A self-designed questionnaire was adopted to collect information on demographic characteristics, physical activity and life style. At the same time, physical examinations including height, weight, blood pressure and blood lipids were carried out.

RESULTSA total of 19 113 participants completed the interviews, physical examinations and collected the blood samples.Excluding those who did not meet the criteria, 14 731 were finally enrolled in the study. The prevalence rates of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH) were 7.16% (1055/14 731, standardized rate:5.46%), 4.60% (677/14 731, standardized rate:4.41%), 7.09% (1045/14 731, standardized rate:5.75%), respectively. Among normal blood pressure group, subjects with normal TC, high TC and abnormal TC were separately 10 571 (88.43%), 1173 (9.81%) and 210 (1.76%); subjects with normal HDL-C and low HDL-C were separately 6885 (57.60%) and 5069 (42.40%); subjects with normal TG, high TG, abnormal TG were separately 9952 (79.91%), 1213 (10.15%) and 1189(9.95%).In ISH group, subjects with normal TC, high TC and abnormal TC were separately 826 (78.29%), 188 (17.82%) and 41 (3.89%); subjects with normal HDL-C and low HDL-C were separately 666(63.13%) and 389 (36.87%); subjects with normal TG, high TG and abnormal TG were separately 737 (69.86%), 150 (14.22%) and 168 (15.92%). Multi factor analysis showed that high TG and abnormal TG were associated with ISH (OR (95%CI):1.43 (1.16-1.76), 1.65 (1.34-2.03) respectively). Among IDH group, subjects with normal TC, high TC, abnormal TC were separately 556(82.13%), 99(14.62%) and 22 (3.25%); subjects with normal HDL-C, low HDL-C were separately 335 (49.48%) and 342 (50.52%); subjects with normal TG, high TG, and abnormal TG separately were 402 (59.38%), 107 (15.81%) and 168 (24.82%). The multi factor analysis showed that high TG and abnormal TG could increase the risk of IDH (OR(95%CI):1.57 (1.24-1.98), 2.18 (1.76-2.70) respectively). Among SDH group, subjects with normal TC, high TC and abnormal TC were 817 (78.18%), 193 (18.47%) and 35 (3.35%); subjects with normal HDL-C and abnormal HDL-C were separately 599 (57.32%) and 446 (42.68%); subjects with normal TG, high TG, abnormal TG were separately 675 (64.59%), 164 (15.69%) and 206 (19.71%). The multi factor analysis showed that high TC, high TG and abnormal TG were also associated with the increased risk of SDH (OR (95%CI):1.38 (1.14-1.67), 1.43(1.18-1.75), 1.73 (1.43-2.10) respectively).

CONCLUSIONDyslipidemia is an important factor of different subtypes of hypertension among Zhejiang population, especially triglycerides. Dyslipidemia screening should be strengthened to reduce the risk of cardiovascular diseases.
