Objective To investigate the correlation between the expression of vascular endothelial growth factor-C(VEGF-C) and lymph node metastasis in gastric cancer. Methods The expression of VEGF-C was detected in 30 pairs of fresh primary gastric cancers and their adjacent normal tissues from the same patients by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. Automated image analyzer was used to quantify VEGF-C expression, which was reflected by positive index (PI). Results VEGF-C was highly expressed in gastric cancer cells,whilst its expression was undetectable in adjacent normal tissues. VEGF-C expression was higher in lymph node metastasis group(PI=1.345?0.079) and lymphatic invasive(PI=1.315?0.037) group than that in no-metastasis group(PI=1.156?0.045) and no-invasive group (PI=1.154?0.043)(P

Objective To investigate the influence of zoledronic acid injection on body temperature of patients with primary osteoporosis.Methods A total of 142 patients with primary osteoporosis who received intravenous zoledronic acid treatment in Peking university people's hospital during 2013-2014 were enrolled in this study.The body temperature before and after intravenous zoledronic acid treatment were recorded and analyzed with SPSS 17.0 software.Results The patients'body temperature at different time points after intravenous zoledronic acid treatment was significantly different (P =0.000).Prophylactic use of NSAIDs could significantly reduce patients' body temperature at the second day after intravenous zoledronic acid.Conclusion NSAIDs can be given orally on the same day of intravenous injection of zoledronic acid,and continued for three days.

OBJECTIVE:To investigate the characteristics and related factors of drug-induced hyperkalemia,present preven-tive measures and provide reference for the rational drug use. METHODS:46 literatures of individual cases and group cases of drug-induced hyperkalemia publicly reported in domestic medical journals from 1979 to 2014 were collected and analyzed statistical-ly,including 66 cases. RESULTS:66 cases with drug-induced hyperkalemia were mainly involved in cardiovascular drugs and im-munosuppressants. Most of them were improved after drug withdrawal and symptomatic treatment,and 2 cases died. CONCLU-SIONS:Drug-induced hyperkalemia are potentially dangerous. It is necessary to be vigilant,prevent and control timely and reduce the incidence of severe adverse reactions.

Objective To explore the sensitivity of contrast-enhanced ultrasound (CEUS) and ultrasonic elastography(UE) in detecting different sizes of thyroid papillary carcinoma.Methods 64 cases of thyroid papillary carcinoma were divided into two groups according to the diameter size(group 1,≤1 cm;group 2,＞ 1 cm) and examined by the contrast-enhanced ultrasound and elastography,then the features were analyzed and the sensitivity for detecting of the two methods in different groups were compared.Results The sensitivity for detecting in CEUS was higher than in UE,which had significant difference between two methods.CEUS and UE were valuable for detecting and they had no difference in sensitivity for detecting in group 1.There was a significant difference in sensitivity for detecting between two methods in group 2.Conclusions Both CEUS and UE were valuable in diagnosis of thyroid papillary carcinoma and the sensitivity for detecting in CEUS is higher than in UE in group 2.

Objective To study the role of OIf-1/EBF associated zinc finger protein (OAZ),a transcription factor encoded by a positional systemic lupus erythematosus (SLE) candidate gene,in the function of mesenchymal stem cells (MSC) of SLE patients by silencing this gene.Methods OAZ mRNA levels of bone marrow MSC obtained from 5 SLE patients and 5 healthy controls were detected by real-time PCR.Bone marrow MSC obtained from 6 SLE patients were incubated with specific siRNAs for 3 days,then cells were harvested for OAZ measurement,Idl-3 and CCL2 mRNA levels were tested by real-time PCR,and levels of CCL2 were detected in culture supernatants using ELISA.Differences between groups were analyzed using t-test or MannWhitney test.Results ① OAZ mRNA levels of bone marrow MSC were significantly elevated in SLE patients (0.013±0.016) compared to healthy controls (0.001±0.000,P=0.009).② After OAZ silencing,the expression levels of OAZ,Id1,Id2 and ld3 mRNA were significantly decreased (△Ct 10.3±0.7,15.2±1.6,8.1±1.4,10.5±0.6 vs 8.7±0.7,14.1±1.2,7.1±1.5,9.8±0.6) (P all ＜0.05).③ Both the expression levels of CCL2 mRNA (△Ct 2.2±1.1 vs 3.0±1.1 ) and the levels of CCL2 protein in culture supernatants [(341±29) pg/ml vs (304±19) pg/ml] were significantly increased in OAZ silencing group comparing to those in the control group (P all ＜0.05).Conclusion OAZ gene expression is significantly elevated in bone marrow MSC of SLE patients.OAZ may affect autoantibody production in SLE patients by regulating CCL2 expression.

Objective To evaluate the application value of polymerase chain reaction (PCR)-fluorescence probe method in identifying genotypes of hepatitis C virus (HCV).Methods One hundred and sixty six serum samples from patients with chronic HCV infection were collected nationwide from March to June 2016.HCV Core-E1 gene region was amplified and sequenced by nested reverse transcription-PCR (RT nested-PCR)and genetic subtypes were analyzed by phylogenetic tree,meanwhile HCV genotypes were also determined by PCR-fluorescent probe method.Kappa test was used to compare the consistency of two methods.Results Among 166 samples detected by RT nested-PCR,the genotype of 66 samples (39.8%) was 1 b,34 (20.5%)was 2a,16 (9.6%)was 3a,27 was 3b (16.2%),23 (13.9%)was 6a.Two samples with 3b genotype detected by RT nested-PCR were identified as 1 b by PCR-fluorescent probe.The consistency rate of two methods was 98.7% (164 /166),there was no significant difference between two methods (χ2 =0.0492,P >0.05).Conclusion PCR-fluorescence probe method can accurately identify HCV genotypes and can be used in clinic.

Objective To investigate clinical characteristics and related factors of ulcerative colitis (UC).Methods One hundred and thirty-seven newly diagnosed patients with UC from 2006 to 2009 in the People's Hospital of Xinjiang Uygur Autonomous Region were selected as our subjects.The clinical data were recorded and the patients were followed up for 3 years.Results Of 137 patients,complete remission rate was 38.69％ (53/137),and partial response rate was 61.31％ (84/137).The overall effective rate was 100％ (137/137).The 1-year cumulative relapse rate was 26.28％ (36/137),and 2-year cumulative relapse rate was 49.64％ (68/137),59.85％ (82/137) for 3-year cumulative relapse rate.The occasion rate (≤ 1 time/year)was 27.01％ (37/137),and frequency (≥2 times/year) was 32.85％ (45/137).Fifty-five patients (40.15％ (55/137)) were no recurrence within 3 years.Relapse rate were not relate to gender (P ＞0.05).The relapse rate of patients less than 50 years was 68.09％ (64/94) substantially higher than that over 50 age group (41.86％ (18/43),x2 =8.444,P ＜ 0.05).The relapse rate of Uygur patients (70.42％,50/71) was substantially higher than the Han (48.48 ％ (32/66),x2 =6.851,P ＜ 0.05).The relapse rate of left colon and extensive colon were 71.64％ (48/67) and 71.88％ (23/32),higher than that of rectum(28.94％,11/38) (P＜ 0.05).The relapse rate of severe group (82.61％,19/23) was higher than that of the mild (52.38％,33/63)and moderate groups (58.82％,30/51) (P ＜ 0.05).In maintenance of mitigation group,52.73％ patients (29/55) were received maintenance treatment and relapse of those patients were significantly higher than recurrence group (31.71％,26/82,P ＜ 0.05).Mental stress may be the top one risk factor,which lead to recurrence of UC (64.63％,53/82),followed by imbalance diet (56.10％,46/82) and overwork (39.02％,32/82).Conclusion Relapse rate of the Uygnr UC patients was higher than that of the Han,and young adults has the higher recurrence rates than the elder.The factors of lesion extent,severity,ability to maintain treatment are related to recurrence of UC.Stress,imbalance diet and overwork are risk factors of recurrence of UC.

BACKGROUND:At present, the main purpose of treatment for degenerative scoliosis is to relieve symptoms, surgicaly correct scoliosis, restore balance and function of the spine, but what kind of techniques is superior has been controversial. OBJECTIVE:To systematicaly assess the clinical effectiveness and safety of short fusion versus long fusion for degenerative scoliosis. METHODS:The databases such as China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journals Database, WanFang Database, The Cochrane Library, PubMed, and EMbase published before May 2015 were electronicaly searched to colect the trials about the short fusion versus long fusion for degenerative scoliosis. Meta-analysis was performed by using RevMan 5.3.4 software. RESULTS AND CONCLUSION: Eleven studies were included, with 533 patients, including 272 cases in the short fusion group and 261 cases in the long fusion group. Meta-analysis results showed that: compare with short fusion group, long fusion group had better improvement of spine Cobb angle (P < 0.000 01) and lordosis angle (P < 0.000 01). No differences were found in the coronal imbalance (P=0.06) and lateral slippage (P=0.24) between the two groups. No significant difference was detected in Japanese Orthopaedic Association score (P=0.93), Visual analogue scale score (P=0.22), and Oswestry Disability Index score (P=0.13) between the two groups. The postoperative complications (P=0.000 6) and the rate of reoperation (P=0.03) were higher in the long fusion group than those in the short fusion group. The incidence of adjacent segment disease has no difference between the two groups (P=0.81). These findings suggest that long fusion is better than short fusion in improvement of the deformity of spine, but incidence of postoperative complications and the rate of reoperation are higher than those in the short fusion group. Comprehensive consideration should be given to the selection of a fixed fusion scheme.
