To study the mechanism ofstimulating effect of 1,25 dihydroxyvitamin D 3 on induction of neovascularization during gastric carcinogenesis induced by N methyl N′ nitro N nitrosoguanidine in rats, gastric carcinogenesis in rats was induced by administration of MNNG (150mg/L) in drinking water. Four weeks after MNNG exposure, rats were fed with diet containing 1,25(OH) 2 D 3 (2.5?g/kg, 5.0?g/kg) . Animals were killed at week 16, and 32 for the study of neovascularization by cardiovascular perfusion with carbon ink and immunohistochemical staining of vascular endothelial cell growth factor (VEGF). Expression of VEGF and microvessel density in glandular stomach of rats receiving 1,25(OH) 2 D 3 ( 5.0?g/kg) in the diet dramatically increased when compared with the rats receiving MNNG alone at week 16, and the differences were more significant at week 32. Expression of VEGF was closely correlated with microvessel density. We propose that certain dose of 1,25(OH) 2 D 3 stimulated neovascularization during gastric carcinogenesis in rats induced by MNNG partly through increasing VEGF expression.

Objective To investigate the changes of molecule markers of pre-thrombotic state,expression of CD62P,concentration of plasma fibrinogen(Fib),prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT) in the patients with essential hypertension for providing theoretical evidence for diagnosis and therapy of thrombus complication in early clinical stage.Methods Fifty-three patients with hypertension(grade Ⅰ 17 cases,grade Ⅱ 16 cases,grade Ⅲ 20 cases)were selected and twenty-eight people with medical examination in good health were used as control group.The expressions of CD62P and CD61 were measured by flow cytometry.The concentration of Fib and the levels of PT,APTT,TT were measured by Class coagulation method.Results The expression of CD62P and the concentration of plasma Fib in essential hypertension group were higher than those in control groups(P0.05).Conclusion The essential hypertensive patients are in pre-thrombotic state,the activation of platelet and blood clotting activity increase.Molecular markers should be measured in essential hypertensive patients for prevention and treatment of thrombotic disease.

Objective To explore the effect of vasoactive intestinal peptide ( VIP) on the prevention and treatment of experimental autoimmune encephalomyelitis(EAE) rats by regulating the levels of IFN-γand IL-17A in brain tissue. Methods Sixty healthy female Wistar rats were randomly divided into 4 groups:normal control group, EAE control group, VIP low-dose group and VIP high-dose group.Myelin basic protein ( MBP)+complete Freurd′s adjuvant ( CFA) was used to establish an EAE model.The low and high-dose VIP groups were intraperitoneally injected with VIP 4 nmol/kg(0.2 ml) and 16 nmol/kg (0.8 ml) respectively every other day,while normal control group and EAE group with 0.8 ml saline for ten consecutive days.The incubation period, progression and peak of neurological dysfunction score ( NDS) changes of rats were recorded.The pathological changes, the GFAP+astrocyte activation in the brain at the morbidity peak of rats and the cytokine levels of IFN-γand IL-17A in brain tissue were observed.Results The incubation period was extended, the progression and peak NDS were shortened in the two VIP groups.In normal control group, there was no inflammatory cell infiltration or active astrocytes in brain tissue.The degree of infiltration of inflammatory cells and the degree of astrocyte activation in the VIP control group were significantly lower than in the EAE group.The cytokine levels of IFN-γand IL-17A in brain tissue were reduced in VIP groups.Conclusion By lowering IFN-γand IL-17A content in brain tissue, the infiltration of inflammatory cells and astrocyte activation are inhibited.VIP plays an important role in prevention and control of EAE.

AIM:To explore the clinical value of combined detection of C-reactive protein ( CRP ) , erythrocyte sedimentation rate ( ESR) and white blood cell ( WBC) count in patients with ocular syphilis.
METHODS:Dates of CRP, ESR, WBC, TPPA and RPR of 51 ophthalmopathy patients caused by syphilis and 50 normal control from Jan. 2012 to Dec. 2015 in eye hospital were recruited and analyzed statistically.
RESULTS:The positive rates of CRP, ESR and WBC of oculopathy patients were 16%, 18% and 39%, respectively, which were higher than those in the control group. In patients group, the positive rate of ESR was higher than CRP and WBC. There were no obvious relationships between RPR titers and positive ratios of CRP, WBC and ESR.
CONCLUSION: The blood level of CRP, WBC and ESR may have certain help in estimating and monitoring condition of patients with ocular syphilis.

Objective :To explore the curative effect of endoscopic sinus surgery (ESS) and the factors associ-ated with surgery effect for treating children with chronic sinusitis. Method :Thirty-one children with a medianage of 10 years (range 5～14 years) who suffered from chronic sinusitis or/and nasal polyps and were operatedvia ESS from May 1996 to January 1999 were retrospectively analyzed. Result:According to the therapeutic evalu-ation standard (ESS-199 7, Haikou ), twelve cases (38.7 ％ ) were completely cured, fifteen cases (48.4 ％0 ) wereinproved and four children (12.9 ％ ) showed no change with a general effective rate of 87.1 ％00 without any severeoperative complication. Conclusion:The results suggested ESS is a safe and effective method in the treatment ofchildren with chronic sinusitis or/and nasal polyps. Furthermore, meticulous postoperative endoscopic care andmedication are also important for securing optimal long-term results.

Objective:To study the molecular composition of bismuth potassium citrate. Methods:The content of bismuth was de-termined using a volumetric method, the content of potassium was determined by atomic absorption spectrometry, and the content of cit-rate root was determined by ion chromatography. The structure was predicted using 1 HNMR and the crystal structure was studied using X-diffraction test and scanning electron microscopy. The changes in the percentage ratio of the three components were investigated by accelerated stability tests. Results:On the dried basis, the percentage of the three molecular components was bismuth of 35%-38%, potassium of 7%-11% and root citrate of 49%-52%. The NMR spectra and the data indicated that the product had three isomers with the molecular structure of bismuth∶potassium∶root citrate=2∶2∶2. The X-diffraction test and SEM showed that the three forms of amor-phous, monocrystalline and polycrystalline might exist. The percentage ratio of the three elements before and after the stability test was basically stable. Conclusion:Bismuth potassium citrate may have three crystal forms with the percentage of the three structure parts within a certain range, and the structure is relatively stable.

Ebosin is a novel exopolysaccharide produced by Streptomyces sp.139 with remarkable activity against rheumatic arthritis in vivo. In this paper, we reported effects of Ebosin on the inflammatory cytokines including interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) in THP-1 cells. With the special fluorogenic peptide as substrates, the enzymatic activities of interleukin-1beta converting enzyme (ICE) and TNFalpha-converting enzyme (TACE) were inhibited by Ebosin separately. Using the real-time reverse transcription polymerase chain reaction (real-time PCR), the mRNA synthesis of the three cytokines were identified decline separately by Ebosin. The secretion quantum of three cytokines in THP-1 cells with Ebosin was lower than that of normal THP-1 cells determined by ELISA assay and Western blotting. All of these results showed that Ebosin has remarkably suppressed synthesis of the three cytokines in THP-1 cells through different pathways. The primary study of Ebosin on anti-inflammation mechanism was promoted developing the new drugs treating rheumatic arthritis.
