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 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 explore how clinical pharmacists exert their effects in drug therapy.Methods The pharmaceutical practice of clinical pharmacist participating in the treatment of one case of warfarin related nephropathy (WRN) was reported.Early identification of warfarin associated nephropathy and early treatment were necessary and the anticoagulant regimen was optimized.Pharmaceutical education was conducted by clinical pharmacist.Results With guidance by clinical pharmacist,the psychological burden of the patient was reduced,the patient compliance was improved,and the patient understanding of adverse drug reactions was increased.Conclusion Clinical pharmacists involved in clinical treatment practice is conducive to timely detecting and treating patients with adverse drug reactions,and improving the level of drug treatment.

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 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.

ObjectiveWith a GcneChip(R) cxpression analysis,98 known gencs and 31 exprcssed sequence tags (ESTs) were found to be differentially expressed between KK/Ta and BALB/c kidneys.To further screen the susceptibility genes for diabetic nephropathy,the temporal and spatial expression patterns of differentially expressed gene-adipsin were investigated.MethodsThe body weight,blood glucose,urinary albumin/creatinine ratio,and renal pathological changes of KK/Ta and BALB/c mice were measured at the 7,20,28 and 36 weeks of age.Total RNA was extracted from the kidney,heart,liver,lung,and brain.The temporal and spatial expression patterns of adipsin in diabetic KK/Ta mice were examined by competitive RT-PCR.The correlation analysis between adipsin expression and albuminuria level was carried out.ResultsThe mRNA expression of adipsin was found in the kidney,heart,lung,and brain,but not in liver.The expression of adipsin in diabetic KK/Ta mice at 20 weeks of age was significantly down-regulated in kidney,heart,and lung than that in age-matched BALB/c mice,and unaltered in brain.Adipsin expression in KK/Ta kidneys was significantly down-regulated with aging and negatively correlated to urinary albumin/creatinine ratio( r =-0.807,P ＜ 0.05).ConclusionsThe expression of adipsin mRNA was downregulated in kidney,heart,and lung in diabetic state.Adipsin expression in KK/Ta kidneys was negatively correlated to urinary albumin/creatinine ratio.It might be a candidate gene for diabetic nephropathy.

Objective To systematically evaluate the efficacy and safety of alprostadil injection in patients with viral hepatitis.Methods Medline,Embase,The Cochrane Library,CBMdisc,CNKI,Wanfang Database and VIP were searched.The quality of included studies such as randomization,blinding,allocation concealment and loss of follow-up were evaluated and meta-analysis was performed by RevMan5.1 software.Results In total,14 RCTs and 1 232 patients were included.Meta-analysis showed that in patients with viral hepatitis,the total effective rate of alprostadil injection treatment was significantly superior to that of conventional therapy (P<0.000 01).Serious adverse drug reactions (ADRs) induced by alprostadil injection were not reported.Conclusion Alprostadil injection is effective and safe for treating viral hepatitis.However,the evidence is not strong due to the generally low methodological quality of RCTs.Further high quality and large sample-sized randomized controlled trials and more pharmacoeconomics studies should be carried out.

OBJECTIVE: To evaluate the applicative value of multimodal navigation combined with intraoperative magnetic resonance imaging system in the treatment of complex lesions of middle skull base. METHOD: Nineteen consecutive patients undergoing complex lesions resection using multimodal microscopic navigation combined with iMRI were included. Preoperative radiological images were imported into navigation planning system, based on which approach and microsurgical window were designed. Transcranial approach and extracranial approach(include trans-oral-nasal-sphenoidal approach and transsphenoidal approach) were performed in our series. After presumptively total resection were finished, intraoperative magnetic resonance (iMRI)were performed, followed by navigation images updating, and continuing resection if necessary. RESULT: iMRI scan were performed from 1 time to 2 times. In 5 cases with residual seen on iMRI scan, continued resection were carried on in 2 of them. There was no iMRI-associated complications. CONCLUSION Microscopic-based neuronavigation, in combination with intraoperative magnetic resonance, could provide objective basis for resection, and improve the safety level of tumor resection.
