Objective To explore the correlation between hyperuricaemia and blood pressure, and blood lipid and glucose. Methods By using simple cluster sampling, 2 branch units from PetroChina Changqing Oilfield Company were selected, and all the 720 subjects with hyperuricaemia (HUA) were assigned to the HUA group; another 620 participants with normal uric acid (UA) level into the normal group. The correlation between blood uric acid and blood pressure,and blood lipid and glucose was assessed by Logistic regression. Results The odds ratio (OR) of those who had 1,2 or 3 abnormal status of hypertension,hyperlipidemia and impaired fasting glucose in the HUA group were much higher than the normal group (OR values were 4. 036,2. 562, and 4. 174, respectively). Logistic regression showed that male, systolic blood pressure ( SBP), GLU, total cholesterol ( TC), triglyceride ( TG), low-density lipoprotein cholesterol (LDL-C) were risk factors of H UA ( OR values were 7. 736,2. 309,1.721,2. 761 and 1. 411,respectively) ,while high-density lipoprotein cholesterol (HDL-C, OR = 0. 211 ) was a protective factor of HUA. Conclusions Gender,blood pressure and blood lipid may have correlation with blood UA. Multiple risk factors should be considered to improve the effectiveness of health education and health promotion.

Objective To establish serum NGAL reference range of healthy populations in Xi'an Area.Methods 2 665 cases (aged 6 to 95 years old,male 1 370,female 1 295) of health-check people were collected from March 2014 to October 2016 in Medical Examination Center of Shaanxi Provincial People's Hospital,and 682 cases (aged 0 to 6 years old,male 356,female 326) were collected from preschool children of prevention.Serum NGAL concentration of them were analysed by immunoturbidimetry method with the Automatic Biochemical Analysis Assembly Line of Beckman-AU5800,and the detection data for statistical analysis.Then established the reference range of serum NGAL population of different age and different sex in Xi'an.Results The serum NGAL levels in healthy subjects showed a skewed distribution,which were preschool children under 6 years of age 37.66±23.12 ng/ml,6～15 years 39.25±25.34 ng/ml,16～49 years 46.68±27.06 ng/ml,and 50～ 69 years 57.82±29.13 ng/ml.Compared the first two with the latter,there was a significant difference (t=0.589,P＜ 0.05).The serum NGAL levels of over 70 years were 61.87 ± 32.64 ng/ml,and there was a significant difference between the ages of 15 and 49 and over 70 years (t=8.529,P＜0.01).At the same time,the serum NGAL was closely correlated with age (r=0.298,P＜0.01).But there was no significant difference in serum NGAL level between male and female (t=0.263～0.542,all P＞0.05).87ng/ml was the upper limit of the reference value for the age of 50 years.Conclusion The level of serum NGAL was related to age and increased with age,but not with gender.

Objective To investigate the effect ofJingzhaotoxin (JZTX) from Chinese tarantula Chilobrachys jingzhao venom on cerebral ischemia/reperfusion injury in mice.Methods Twenty mice were equally randomized into normal group,sham-operated group,vehicle group and JZTX treatment group (n=5).Cerebral ischemia-reperfusion injury was induced by middle cerebral artery occlusion.Cerebral infarct volume was measured by TTC staining.The superoxide dlsmutase (SOD) activity and malonaldehyde (MDA) content in serum were detected with colorimetric method.Immunohistochemistry and real-time PCR were used to analyze the expressions of cyclooxygenase-2 (COX-2).Results The cerebral infarct volume in the JZTX treatment group was significantly decreased as compared with that in the vehicle group (P＜0.05); higher SOD activity and lower MDA content in the JZTX treatment group after ischemic insult were noted than those in the vehicle group (P＜0.05); the mRNA and protein expressions of COX-2 in the JZTX treatment group was significantly down-regulated as compared with those in the vehicle group (P＜0.05).Conclusion JZTX has neuroprotective effect in cerebral ischemia/reperfusion injury,whose mechanism might be related to the improvement of antioxidant capacity and the down-regulation of COX-2 expressions after cerebral ischemia.

OBJECTIVETo explore the feasibility of percutaneous vertebroplasty for the treatment of acute burst thoracolumbar fracture.

METHODSFifty-eight patients (male 38 and female 20, ranging in age from 38 to 70 years, with an average of 56.8 years) with acute burst thoracolumbar fracture were treated by percutaneous vertebroplasty. The injuried vertebrae were T11 in 3 cases, T12 18 cases, L1 29 cases, L2 5 cases and L3 3 cases. All suited cases were classified into 3 types according to injuried vertebral shapes,type I (safe type 26 cases), type II (risk type 21 cases), and type III (marginal type 11 cases).

RESULTSAll the patients were followed up ranging from 1 to 2.5 years (mean 1.6 years). Fifty-three patients could walk in 1 to 3 days after operation. Among 55 patients who obtained complete recovery (CR), 39 patients could do daily works and 16 patients could do houseworks. The CR rate was 95%. Three patients who obtained partial recovery (PR), could live by themselves and felt slight lumbago after movements. The PR rate was 5%.

CONCLUSIONPercutaneous vertebroplasty for the treatment of acute burst thoracolumbar fracture is a feasible and effective method even for particular risks.

OBJECTIVETo investigate the possibility and the limit in increasing the survival area of the random skin flap by extremely increasing the ratio of its length and width within 24 hours.

METHODSSD rats (n = 20) were chosen for this study. The rats were randomly divided into: subject group and control one. Pre-made skin flap was prepared as design. The subject group was carried out rapid pre-fabricated skin flap formation training. No training was performed in control group. The changes in perfusion value of micro-circulation inside skin flap were monitored during the whole process, and micro-circulation parameters of the skin flap were used to evaluate whether its blood circulation network was mature or not.

RESULTSTraining of pre-made skin flap at 18th hour, the perfusion value of its micro-circulation was basically stable, Skin flap formation was finished at 24th hour. Survival area in control group was (68.25 +/- 0.18)% and in subject group was (97.25 +/- 0.24)% (P < 0.01). There was a significant difference between the two groups.

CONCLUSIONSWithin short time, it is possible to establish micro-circulation in skin flap which exceeds the limit set by traditional theory. Digitalized judgment can be used to monitor the fast formation of super-big skin flap. This method is reliable and can increase the survival rate of random skin flap.

OBJECTIVETo identify gene expression differences between abdominal aorta aneurysm (AAA) and normal abdominal artery.

METHODSFive AAA specimens and five normal abdominal artery specimens were collected. Total RNA was extracted and purified from the samples independently. Then isolated RNA was labeled and hybridized onto the Affymetrix Genechip.

RESULTSOne thousand nine hundreds and sixty-two differently expressed genes were identified in AAA compared with normal abdominal artery, of which 554 genes were up-regulated and 1408 genes were down-regulated. Functional analysis revealed that genes involved in immune response, inflammatory response and chemokines were significantly up-regulated in AAA.

CONCLUSIONThe differently expressed genes may be useful in providing new insights and foster a better understanding of the mechanism of AAA.

Objective:To establish a real-time fluorescent quantitative PCR for the detection of torque teno virus types 7 (TTV7), 8 (TTV8) and 10 (TTV10) and analyze its performance in clinical sample detection.Methods:Specific primers were designed based on the gene sequences of TTV7, TTV8 and TTV10 in GenBank. Recombinant plasmids of pMD19-T-TTV7, pMD19-T-TTV8 and pMD19-T-TTV10 were constructed and used as positive standard control to establish a real-time fluorescent quantitative PCR based on FAM-Eclipse probe method. The specificity and sensitivity of the established method were evaluated. Moreover, it was validated in terms of clinical sample detection.Results:The standard curve equations of the real-time fluorescent quantitative PCR for detecting TTV7, TTV8 and TTV10 were y=-0.340 2 x+ 114.780 0 ( R2=0.998 8), y=-0.351 1 x+ 114.940 0 ( R2=0.995 3) and y=-0.348 9 x+ 115.020 0 ( R2=0.991 7), respectively, and there was no cross-reaction with other viruses. The detection sensitivity of the established method for TTV7, TTV8 and TTV10 were 108 copies/μl, 84 copies/μl and 98 copies/μl, and the positive detection rates in clinical pediatric serum samples were 10.9%, 2.1% and 4.3%, respectively. Conclusions:The established real-time fluorescent quantitative PCR for detection of TTV7, TTV8 and TTV10 was featured by strong specificity and high sensitivity, which could be used for rapid TTV detection in clinical serum samples.

OBJECTIVETo investigate factors associated with survival of patients with Ph chromosome positive adult acute lymphoblastic leukemia (aALL) in a period of 11 years.

METHODSAll the clinical parameters of 31 Ph positive patients were statistically analyzed by SPSS software.

RESULTPh(+) patients account for 15.3% (31/203) of all the aALL patients. Clinically, these patients manifested older in age, higher white blood cell counts with high blast fractions and lower platelet counts (PC). Phenotypically 82.6% of them were common ALL, 39.1% coexpressed myeloid antigens, and 56.5% expressed CD34 antigen. 65.4% of them (17/26) achieved complete remission (CR) and the median remission and survival durations were 4 months and 8 months, respectively. Patients with Ph(+) and additional chromosomal aberrations accounted for 42% of all the Ph(+) patients, including monosomy 7, +Ph, del(9)(p11-12) and add/t(16)(p13), and they had lower PC as compared with those with sole Ph(+) (P = 0.012) and variant Ph translocation (P = 0.01). CD34 positive patients had a shorter remission and survival duration than CD34 negative ones (0 vs 9 months for median remission time, P = 0.024; and 6 vs 12 months for median survival time, P = 0.034). There was no evidence to support the correlation between myeloid antigen expression and survival time in these patients.

CONCLUSIONPh(+) aALL is associated with adverse prognosis and CD34 expression is a poorer prognostic factor in Ph(+) aALL patients. There is no significant clinical difference between Ph(+) aALL with or without additional chromosomal aberrations.

OBJECTIVETo evaluate the fast serum pepsinogen level of the healthy adults among local population in areas with high incidence of gastric cancer and to study the suitable cut-off values of serum pepsinogen abnormality for the screen of chronic atrophic gastritis (CAG) and gastric carcinoma (GC) in China.

METHODSSerum PG I and PG II levels were detected with time resolved fluorescence immunoassay (TRFIA). The fast serum PG I and PG I level as well as PG I/PG II ratio of 606 healthy adult residents among local population in Zanhuang county, Hebei province were detected and the normal distribution ranges determined. The relationship between different cut-off values of serum PG I level, PG I/PG II ratio and corresponding pathological changes in gastric mucosae were comparatively analyzed with serum PG detection, endoscopic biopsy and pathological observation in 720 cases of local residents receiving endoscopic examination in the high incidence area of gastric cancer. The efficacy, sensitivity and specificity of different PG I, PG II abnormality cut-off values in the screen p rogram of CAG and GC were statistically analyzed.

RESULTSThe serum PG I, PG II and PG I/PG II ratio levels of healthy adults from a local natural population in the high incidence area of gastric cancer were all skewed from normal distribution. The median level of PG I, PG II and PG I/PG II were 161 microg/L, 14.8 microg/L and 10.5 respectively. Data from comparative studies on serum PG level and pathological changes of gastric mucosae showed that within the serum PG I range from 40 microg/L to 80 microg/L and PG I/PG II ratio range from 3 to 8, sensitivity of the screening program for CAG and GC increased while the specificity decreased along with the increase of cutoff values of serum PG I and PG I/PG II ratio. Results from statistical receiver operator characteristic curve (ROC) analysis suggested that the best cut-off value of PG I and PG I/PG II abnormality for the screening of CAG and GC being PG I < or =60 microg/L,PG I/PG II < or =6 respectively.

CONCLUSIONThe serum PC I, PG II and PG I/PG II ratio levels of healthy adults from a local natural population in the high incidence area of gastric cancer were all skewed from normal distribution. Serum PG I < or =60 microg/L and PG I/PG II ratio < or =6 as abnormal cut-off value for the screen of CAG and GC could result relatively good sensitivity and specificity.
