Totally 1 360 pregnant women during the first trimesters (4-12 weeks) who visited Ningbo University Affiliated Hospital and Ningbo Jiangbei Maternal Health Hospital from February 2010 to October 2011,and 216 non-pregnant healthy women,who contemporaneous by visited the hospital,were enrolled in this study.The thyroid screening was made by determining urinary iodine and serum free thyroxine,free triiodothyronine,total thyroxine,total triiodothyronine,thyrotropin,and thyroid peroxidase antibody (TPOAb).The median concentration of urinary iodine in the pregnant women was not different from that of non-pregnant women (P>0.05) ; 1 360 pregnant women were screened,268 (19.71%) of them were identified to suffer from thyroid disorders or with positive thyroid autoantibody.29(13.43%) of non-pregnant women were identified to suffer from thyroid disorders or with positive thyroid autoantibody.There was significant difference between the 2 groups (x2 =4.40,P<0.05).Prevalence of thyroid dysfunction may increase during early pregnancy.The screening for thyroid function and autoantibody should be recommended in that period.

Objective To understand the pattern of and influencing factors on leisure time physical exercises among adults in Zhejiang. Method Totally 17 437 residents aged 18 years and over selected by stratified cluster random sampling in Zhejiang in 2010 were investigated. Result Overall 21.82%(95%CI:17.12%-27.38%) of adults took part in leisure time physical exercises in 2010. The proportion was higher in urban (29.04%,95%CI:23.46%-35.33%) than in rural (18.81%,95%CI:12.89%-26.61%) (χ2=222.06, P<0.05) areas, and also higher in females (22.91%,95%CI:17.66%-29.15%) than in males (20.56%,95%CI:16.39%-25.48%) (χ2=13.94, P<0.05). Adults aged 18-24 and 55-74 years were more likely to take apart in physical exercises (χ2=266.73, P<0.05), and the lowest proportion was found among farmers (5.33%,95%CI:3.99%-7.11%) (χ2=2 078.40, P<0.05). These proportions both increased along with education level and family income increase (χ2=444.87, P<0.05;χ2=332.20, P<0.05). Overall 83.04%and 90.08%of physical exercisers took part in exercises at least 3 times per week and 30 minutes per time, only 30.67% of those reached moderate or vigorous intensity, and overall 5.38% (95%CI: 3.85%-7.48%) of adults took part in regular leisure time physical exercises in 2010. Multiple logistic regression showed that age, education level, occupation and chronic disease history have influence on regular physical exercises. Conclusion The leisure time physical exercises level was generally low among adults in Zhejiang. Young and middle-aged adults with less education and low income especially farmers should be put on emphasis.

OBJECTIVETo compare the intervention effects of four traditional Chinese medicines (TCMs) with typical cold or hot property on body temperature and temperature-sensitive transient receptor potential ion channel proteins (TRPs) of rats with yeast-induced fever.
METHODThe pyrexia model was induced by injecting yeast suspension subcutaneously. Totally 108 male SD rats were randomly divided into the normal group, the model group, the Rhei Radix et Rhizoma treated group, the Coptidis Rhizoma treated group, the Euodiae Fructus treated group, and the Alpiniae Officinarum Rhizoma treated group, with 18 rats in each group. At the 4 h, 8 h and 12 h after injection of yeast, the rats were sacrificed to collect their hypothalamus and dorsal root ganglion. The expressions of TRPV1 and TRPM8 were detected by immunohistochemistry and Western blot method.
RESULTCompared with the normal group, after injection of yeast, the temperature of rats in the model group notably increased, and reached the peak at 8 h (P < 0.01). The TRPV1 level in hypothalamus and dorsal root ganglia (DRG) of the model group significantly increased, whereas the TRPM8 level significantly reduced. Compared with the model group, the Rhei Radix et Rhizoma group and the Coptidis Rhizoma group showed significant decrease in the high body temperature of rats caused by yeast, down-regulation in the expression of TRPV1, and up-regulation in the expression of TRPM8 (P < 0.05 or P < 0.01). Euodiae Fructus and Alpiniae Officinarum Rhizoma had no significant effect on either temperature or TRPs of fever rats.
CONCLUSIONRhei Radix et Rhizoma and Coptidis Rhizoma, both are TCMs with cold property, can reduce the temperature of fever rats induced by yeast, which may be related to their effective regulation of TRPV1 and TRPM8 in hypothalamus and DRG, while Euodiae Fructus and Alpiniae Officinarum Rhizoma had no relevant effect.

Adult intussusception is rare involving of only 1% of the causes of bowel obstruction. We report a case of a 39-year-old female with intussusceptions due to inverted Meckel's diverticulum. She visited our hospital for diffuse abdominal pain during 1 week and aggravated abdominal pain for 2 days. Vital signs were stable, and there was periumbilical tenderness. She had no history of abdominal operation. CT scan showed a 3.7x2.1 cm of fatty mass with focal intussusception in the distal ileum. When the emergency operation was performed, the patient was found to be suffering from ileocolic intussusception. A manual reduction of intussusception showed inverted Meckel's deverticulum at 65 cm proximal to the ileocecal valve, and the segmental resection of small bowel including a Meckel's diverticulum was performed. Pathologic examination revealed a Meckel's diverticulum containing a 0.6x0.6 cm sized aberrant pancreas.

·AIM: To analyze the clinical efficacy and safety of vitrectomy combined with cyclophotocoagulation in the treatment of traumatic glaucoma, and to provide an effective treatment for improving the quality of life of patients with traumatic glaucoma. ·METHODS:Totally 90 patients (90 eyes) with traumatic glaucoma admitted in our hospital from January 2011 to July 2016 were divided into two groups (45 patients in each group) according to different treatment methods. The patients in the observation group underwent vitrectomy combined with cyclophotocoagulation under direct vision; the control group underwent vitrectomy combined with trans-scleral cyclophotocoagulation. We observed the effect of different treatment on visual acuity, intraocular pressure and complication of the two groups. ·RESULTS: The visual acuity of the observation group was significantly better than that of the control group after treatment (Z=-5.689, P<0.05). There was no significant difference on intraocular pressure between the two groups before treatment (P>0. 05). The change of decreased intraocular pressure in the observation group was less than that in the contral group after operation (P<0.05). After 1a follow-up,there was no significant difference on the change of decreased intraocular pressure between the two groups (P>0. 05). The complications of the two groups after treatment were vitreous hemorrhage, choroidal detachment, low intraocular pressure, increased intraocular pressure and other complications, but the complication rate of two groups were no different (x2=1.553,P=0.213).· CONCLUSION: Vitrectomycombinedwith cyclophotocoagulation under direct vision brings patients better visual acuity than that combined with trans-scleral cyclophotocoagulation.

BACKGROUND: Thus far, research studies on community-acquired pneumonia (CAP) have focused on its clinical severity. Recently, it has been determined that procalcitonin (PCT) level is correlated with severity of CAP. A retrospective study conducted at our hospital used risk predictability and PCT to determine whether or no PCT is useful in assessing the severity of CAP. METHODS: This study covered 92 CAP cases that were admitted to the respiratory department at Changwon Fatima Hospital between July 1, 2008 and June 30, 2009. All enrolled subjects were measured for infection markers and risk predictability. RESULTS: Based on hospital admission data, enrolled subjects had Pneumonia Severity Index (PSI) scores serving as risk predictors showed that both PCT and white blood cell (WBC) were statistically significant as infection markers (p=0.001, 0.037). Thus, this study used ROC curves in PSI for data analysis. As a result, it was determined that the area under curve (AUC) of PCT and WBC was 0.694 and 0.593 respectively, indicating that PCT has a higher test value for WBC, when PCT was higher than 0.745 ng/mL. In addition, it was found that PCT levels higher than 0.745 ng/mL had higher PSI scores than the group with PCT lower than 0.745 ng/mL (p=0.032). CONCLUSION: In order to predict risk of pneumonia cases admitted due to symptoms of CAP, it is important to consider PCT as well as PSI, and follow-up monitoring of PCT cases.
