OBJECTIVETo explore the association between C825T polymorphism of G protein beta3 subunit (GNB3) gene and different Hilit types of essential hypertension (EH) in the Uygur nationality of Xinjiang.

METHODSAccording to Uygur medical theories, EH patients (as the EH group) and non-EH patients (as the control group) were assigned to four Hilit groups. The C825T polymorphism of GNB3 was detected in 161 EH patients and 379 non-EH subjects of different Hilit types by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to explore the difference of the genotypes and allelic frequencies and hypertension.

RESULTS(1) In Xinjiang Uygur population, the distribution frequencies of GNB3 C825T polymorphism were in accordance with Hardy-Weinberg (chi2 = 0.871, P = 0.647). (2) There was no statistical difference in the distribution frequencies of three genotypes and two alleles of GNB3 between the EH group and the control group (P > 0.05). (3) There was statistical difference in distribution frequencies of three genotypes between the abnormal Sapra and non-abnormal Sapra group (the sum of abnormal Sewda, abnormal Kan, and abnormal Balhem) (chi2 = 6.905, P = 0.032), especially between the abnormal Sapra and abnormal Balhem groups (chi2 = 10.404, P = 0.006), but there was no statistical difference in distribution frequencies of alleles between the two groups (P > 0.05). (4) In 161 EH patients, there was statistical difference in the distribution frequencies of three genotypes and two alleles between the abnormal Sapra and non-abnormal Sapra group (chi2 = 9.034, P = 0.011; chi2 = 4.701, P = 0.03).

CONCLUSIONSBoth TT genotype and T allele of GNB3 C825T polymorphism might not be associated with EH patients in Xinjiang Uygur populations. However, they were correlated with hypertension patients of non-abnormal Sapra, indicating the pathogeneses of EH with different Hilit types might be different.

AIMFor further investigating of heat shock transcription factor 1 (HSF1) action in thermoregulation and its physiological mechanism.

METHODSThe relationship among the expression of HSF1 and interleukin 1beta (IL-1beta) mRNA and tumor necrosis factor alpha (TNF-alpha) mRNA in monocytes was studied during the different fever stages in rabbit fever model induced by LPS. The expressions of IL-1beta and TNF-alpha mRNA were measured by RT-PCR assay; HSF1 expression was measured by Western blot.

RESULTS(1) Intravenous injection of LPS produced a double-peak temperature arisen at 60 min and 180 min. (2) The expression of IL-1beta mRNA in monocytes had a peak at 160 min, while the peak of TNF-alpha mRNA expression occurred at 80 min after intravenous injection of LPS. (3) The content of the HSF1 trimer increased gradually after 160 min intravenous injection of LPS. The results indicated that the content of the HSF1 trimer was negative correlation with the expressions of IL-1beta mRNA and TNF-alpha mRNA, and the change in body temperature was a positive correlation with IL-1beta mRNA.

CONCLUSIONIt is possible that HSF1 limits the rise in body temperature by repressing the gene expressions of the endogenous pyrogen, IL-1beta and TNF-alpha.

Background Glaucoma is one of the leading causes of blindness worldwide;while the different types of glaucoma is vary from different region. Objective Present study was to survey the prevalence and types of glaucoma among peasants of Uigur adults in Kuche county and offer the basis for the prevent and treatment of glaucoma in Uigur nationanlity. Methods 4191 Uigur peasants aged 40 years or above were collected in Kuche county for the survey of prevalence and types of glaucoma by randomized cluster sampling in March and April of 2009. The subjects were grouped into 40-,50-,60- and ≥70 years groups according to the distribution of age. The disease history of glaucoma, regular eye examination, funds examination and measurement of the anterior chamber depth, gonioscope were performed in the all subjects. Darkroom prone test and mydriasis test were carried out in suspicious glaucomous patients. The depth of periphery anterior chamber was assessed based on van Herick' s criteria, and the width of chamber angle was graded based on Scheie' s method. The standardized training was performed. This survey approved by Xinjiang Medical Ethics Committee, all subjects signed the informed consent before the examination. Results 4191 of 4873 subjects finished all the examinations with the response rate 86%. All the subjects showed a good compliance. The prevalence of glaucoma was 3. 79% , and the prevalence of primary angle-closed glaucoma(PACG) .primary angle-open glaucoma (PAOG) and secondary glaucoma was 2.22% ,0.26% and 1. 31% respectively, showing a significant difference among the different types of glaucoma( P<0. 05). The prevalence of glaucoma was elevated with aging (χ2 - 116. 69 ,P<0. 05) and presented a high rate in male subjects compared with female ones(χ2 = 7. 34, P<0. 05 ). Bilateral blindness was found in 19.75% glaucoma peasants, in which 25.3% glaucoma peasants received anti-glaucoma surgery. The distribution of visual acuity of patients was of significant difference among different age groups(χ2 = 37. 69 ,P<0. 05 ) . Conclusions The prevalence of the glaucoma among Uigur peasants in Kuche county was higher than most area no matter inland or overseas. PACG still is the common type in those people.

Objective To find out severity and types of syphilis infection in blood donors, attendants and persons to have their premrital medical examination in Zhoushan City and offer a new measure for prevention and treatment of syphilis. Methods Totally, 174 589 blood donors, attendants and persons to have their premarital medical examinations were screened preliminarily for inapparent syphilis with non-TPHA, and then TPHA was applied to confirm the diagnosis, according to the National Standard No. GB 15974-1995, combining with clinical symptoms and physical check-up. Results A total of 1 327 cases of syphilis from 174 589 samples tested, including blood donors, attendants and persons to have their premarital medical examinations, were diagnosed, with an inapparent infection rate of 7. 60‰ in average, 6. 42‰in males and 8. 74‰ in females, with a sex ratio of 0.71 (X2 = 29. 92, P

OBJECTIVETo detect the expression of surface molecule CD96 on stem cell (LSC) in children with acute leukemia, and to explore its clinical significance.

METHODSBone marrow mononuclear cells were isolated in 69 children with newly diagnosed acute leukemia. CD34(+)CD38(-)CD123(+) LSCs were separated from these cells by flow cytometry (FCM) and then cultured, and CD96 expression on LSCs was detected by FCM. R-banding technique was used to analyze the karyotypes of the 69 children, and the data of their routine blood and immunological tests were collected.

RESULTSCD96 was mainly expressed in children with acute myelogenous leukemia, and expressed to a lesser extent in those with acute lymphoblastic leukemia (P<0.05). The median expression level of CD96 in Uyghur children was 23.4%, versus 21.2% in Han children (P>0.05). The majority of children with CD96-positive children presented poor-prognosis karyotypes. Compared with CD96-negative children, children with CD96-positive children had a significantly lower complete remission rate (P<0.05) and significantly higher infection and relapse rates after chemotherapy (P<0.05).

CONCLUSIONSChildren with acute leukemia who have CD96-positive LSCs have a poor prognosis. CD96 may be a new indicator of prognosis in children with acute leukemia.

ObjectiveTo explore the application value of individualized surgical treatment based on the CT portal venograpy (CTPV) classiifcation in cirrhotic portal hypertension.MethodsOne hundred and iffty-six patients with cirrhotic portal hypertension who received surgical treatment in Anhui Province Hospital between June 2010 and December 2014 were enrolled in this prospective study. According to different surgical procedures, the patients were divided into two groups: the individualized surgery based on CTPV classiifcation group (classification group) and traditional surgery group (traditional group). Among the 84 patients in the classiifcation group, 56 were males and 28 were females with the age ranging from 19 to 67 years old and the median of 45 years old. Among the 72 patients in the traditional group, 47 were males and 25 were females with the age ranging from 23 to 62 years old and the median of 43 years old. The informed consents of all patients were obtained and the local ethical committee approval was received. The patients in the classiifcation group underwent individualized surgery according to the pre-operative CTPV classiifcation, while the patients in the traditional group underwent splenectomy + pericardial devascularization. The effects of two surgical procedures on the portal hypertension, intraoperative and postoperative conditions and postoperative survival rate of the patients were observed. The observation indexes of two groups were compared usingt test and survival analysis was conducted using Kaplan-Meier method and Log-rank test.ResultsThe postoperative free portal pressure (FPP) in the classiifcation group was (27±3) cmH2O (1 cmH2O=0.098 kPa), signiifcantly lower than (33±8) cmH2O in the traditional group (t=-3.355,P<0.05). The FPP decrease range before and after surgery in the classiifcation group was (13±6) cmH2O, signiifcantly higher than (9±5) cmH2O in the traditional group (t=3.016,P<0.05). The length of surgery and intraoperative blood loss in the classiifcation group were respectively (188±84) min and (378±49) ml, significantly less than (240±76) min and (463±57) ml in the traditional group (t=-2.687,-3.015;P<0.05). The postoperative length of stay and hospitalization expense in the classiifcation group were respectively (12±4) d and (31 000 ± 15 000) yuan, signiifcantly lower than (15±5) d and (36 000±15 000) yuan in the traditional group (t=-2.061,-2.104;P<0.05). The 1, 3-year accumulative survival rate were respectively 94.05% and 85.71% in the classiifcation group, and were respectively 87.50% and 68.05% in the traditional group. The overall survival rate in the classiifcation group was signiifcantly higher than that in the traditional group (χ2=7.000,P<0.05).ConclusionsPre-operative CTPV classification and individualized surgical treatment for patients with cirrhotic portal hypertension can effectively reduce the portal vein pressure and has the advantages of smaller injury and better prognosis.

OBJECTIVEIntra-ventricular hemorrhage (IVH) is one of the most serious complications of preterm infants. Significant numbers of the surviving infants with severe IVH go on to develop post-hemorrhagic hydrocephalus (PHH). The management of PHH remains a very challenging problem for both neonatologists and pediatric neurosurgeons. This study aimed to evaluate the efficacy and safety of the use of Ommaya reservoirs and serial cerebrospinal fluid (CSF) drainage in the management of a series of neonates with PHH.

METHODBetween January 1, 2003 and December 30, 2005, 15 consecutive newborn infants with IVH grades III to IV, complicated with progressive ventricular dilatation, underwent placement of an Ommaya reservoir. CSF was intermittently aspirated percutaneously from the reservoir. The amount and frequency of CSF aspiration were based on the clinical presentation and the follow-up results of serial cranial ultrasonograms or CT scans. The changes of CSF cell counts and chemistries were also followed. Patients whose progressive ventricular dilatation persisted despite serial CSF aspiration through Ommaya reservoir eventually had ventriculo-peritoneal shunts (V-P shunt) placed. All the patients were followed up in the outpatient clinic after discharge from the hospital and the neurodevelopmental outcomes were evaluated through 18-36 months of age.

RESULTA total of 15 infants were included in this series. Of them, 11 were preterm infants who were at gestational ages of 29 to 34 weeks and 4 infants were full-term. All of the 4 full term infants presented with progressive ventricular dilatation after suffering from the intra-cranial hemorrhage (3 infants were due to vitamin K deficiency and 1 was due to birth trauma). Thirteen infants had grade III IVH, and 2 had grade IV IVH based on initial cranial ultrasonographic and CT scans. The mean age when IVH was diagnosed was (9 +/- 1) days in preterm infants and (22 +/- 7) days in full-term infants; the mean age when Ommaya reservoir was placed was (18 +/- 11) days in preterm infants and (31 +/- 7) days in full-term infants. All the infants tolerated the surgical procedure well. The Ommaya reservoir was tapped for an average of (21.5 +/- 4.6) times per patient. The mean CSF volume per tap was (10.2 +/- 1.3) ml/kg. The values of CSF protein, glucose and cell counts slowly reached normal levels at approximately 3 - 5 weeks after the placement of the reservoir. The velocity of head circumference increase per week was less than 1 cm in 13 patients in 1 - 4 weeks after the placement of the reservoir and the size of ventricles decreased gradually. By 12 - 18 months, 12 infants had normal size ventricles, and 1 patient still had mild ventricular dilation at 36 months. Two infants developed progressive hydrocephalus after serial CSF aspiration through Ommaya reservoir. One infant had a V-P shunt placed at 2 months of age and another infant died at 3 months of age at home after parents refused further therapy. Complications consisted of reservoir leaking and CSF infection at 16th day of placement in one patient after repeated tapping. By the end of 18 - 36 months of follow-up, 11 of 14 infants were considered normal, two patients had mild impairment in neurodevelopmental outcome (both had spastic bilateral lower limbs paresis, and one of whom also had amblyopia) and the other had seizure disorder.

CONCLUSIONThe results from this series indicate that the placement of an Ommaya reservoir is relatively safe in newborn infants and is useful in the initial management of neonates with PHH and may be beneficial in improving their neurodevelopmental outcomes. A multicenter randomized trial may be needed to further validate the results of this report.

BACKGROUND: Few studies have examined ambulatory cardiovascular physiological parameters of taxi drivers while driving in relation to their occupational hazards. This study aims to investigate and quantify the impact of worksite physical hazards as a whole on ambulatory heart rate of professional taxi drivers while driving without their typical worksite psychosocial stressors. METHODS: Ambulatory heart rate (HRdriving) of 13 non-smoking male taxi drivers (24 to 67 years old) while driving was continuously assessed on their 6-hour experimental on-road driving in Los Angeles. Percent maximum HR range (PMHRdriving) of the drivers while driving was estimated based on the individual HRdriving values and US adult population resting HR (HRrest) reference data. For analyses, the HRdriving and PMHRdriving data were split and averaged into 5-min segments. Five physical hazards inside taxi cabs were also monitored while driving. Work stress and work hours on typical work days were self-reported. RESULTS: The means of the ambulatory 5-min HRdriving and PMHRdriving values of the 13 drivers were 80.5 bpm (11.2 bpm higher than their mean HRrest) and 10.7 % (range, 5.7 to 19.9 %), respectively. The means were lower than the upper limits of ambulatory HR and PMHR for a sustainable 8-hour work (35 bpm above HRrest and 30 % PMHR), although 15–27 % of the 5-min HRdriving and PMHRdriving values of one driver were higher than the limits. The levels of the five physical hazards among the drivers were modest: temperature (26.4 ± 3.0 °C), relative humidity (40.7 ± 10.4 %), PM2.5 (21.5 ± 7.9 μg/m3), CO2 (1,267.1 ± 580.0 ppm) and noise (69.7 ± 3.0 dBA). The drivers worked, on average, 72 h per week and more than half of them reported that their job were often stressful. CONCLUSIONS: The impact of physical worksite hazards alone on ambulatory HR of professional taxi drivers in Los Angeles generally appeared to be minor. Future ambulatory heart rate studies including both physical and psychosocial hazards of professional taxi drivers are warranted.

PURPOSE: Patients with gestational diabetes mellitus (GDM) have been reported to exhibit the same genetic susceptibility as that observed in those with type 2 diabetes mellitus (T2DM). Recent polymorphism studies have shown that several genes are related to T2DM and GDM. The aim of this study was to examine whether certain candidate genes, previously shown to be associated with T2DM, also offer a specific genetic predisposition to GDM. MATERIALS AND METHODS: The current study was conducted in 136 Korean pregnant women, who gave birth at Gil Hospital, from October 2008 to May 2011. These study subjects included 95 subjects with GDM and 41 non-diabetic controls. We selected the specific genes of PPARgamma2, IGF2BP2, and KCNQ1 for study and amplified them using the polymerase chain reaction. This was followed by genotyping for single nucleotide polymorphisms. We then compared the genotype frequencies between patients with GDM and non-diabetic controls using the chi2 test. We obtained and analyzed clinical information using Student's t-test, and statistical analyses were conducted using logistic regression with SPSS Statistics software, version 19.0. RESULTS: Significant differences were observed in maternal age, body mass index, weight gain and weight at time of delivery between the groups compared. Among pregnant women, polymorphisms in PPARgamma2 and IGF2BP2 were shown to be highly correlated with GDM occurrence, whereas no correlation was found for KCNQ1 polymorphisms. CONCLUSION: Our results indicated that genetic polymorphisms could also be of value in predicting the occurrence and diagnosis of GDM.
