Objective:Helicobacter pylori is one of the human pathogens causing gastric ulcers and cancers.A key virulence factor of H.pylori is the Cag pathogenicity island,which encodes a type IV secretion system.HP0525 is an essential component of the Cag system and acts as an inner membrane associated ATPase.To construct recombinant plasmid containing hp0525 gene of Helicobacter pylori(H.pylori)NCTC 11637,and analysis of sequence nucleic acid,express it in E.coli BL21 and study the influence of the HP0525 protein on proliferation of SGC-7901 cells.Methods:H.pylor hp0525 gene was amplified from the genome DNA by PCR,then operated T-A cloning and sequenced.The hp0525gene fragment was inserted directionally into vector pMD18-T to construct recombinant clones of hp0525 and was sequenced.The recombinant plasmid was transformed into E.coli BL21for expressing under induction of IPTG.Purify the expressed protein by Ni2+-NTA column chromatography.Expressed product was analyzed by Western blot and MALDI-TOF.Added the purified protein into SGC-7901 cells,the effect of cell proliferation in SGC-7901 cells induced by the recombinant protein was observed by MTT.Results:A 993 base pairs long hp0525 gene,which encodes a product of 330 amino acid,was obtained using PCR method and was cloned into pMD18-T vector successfully.The sequence analysis for hp0525 showed that it shares 97%~99% homology with other strains in Gene bank.SDS-PAGE showed a protein band with a relative molecular weight of 36 000,which was consistent with the expectation.The expressed product reached a purity of 97% after Ni2+-NTA column chromatography.The protein after dialyzed and annealed,was co-cultured with SGC-7901 cells,The protien of different concentration co-cultured with SGC-7901 cells for different times,found that the protein in low concentration stimulates proliferation of cells,to achieve some concentration,it inhibits proliferation of cells along with multiplication of the concentration of the protein;The protein inhibits proliferation of cells relay on the extension of time and concentration.Conclusion:It is indicated that the correct hp0525 gene was obtained and expressed in E.coli BL21.High purified protein was obtained by Ni2+-NTA column chromatography,the protein can inhibits proliferation of SGC-7901cells,and T-ATPase activity which posed a basis for further researching on its biological function.

Objective To estimate the efficacy and safety of Voriconazole as antifungal prophylaxis of invasive fungal infection ( IFI) for malignant hematology patients. Methods The randomized controlled trials of Voriconazole treatment in invasive fungal infection for malignant hematology patients (ended in September 2014) were searched from Cochrane library, Medline, Embase, Pubmed, CBM, CNKI, Blood database. The meta analysis were performed by RevMan5.0. Results Ten literatures reported in 1 773 cases, in which there was significantly difference in effective rate between Voriconazole and other antifungal agents such as Amphotericin-B, Itraconazole, Micafungin and Fluconazole(P < 0.000 01); Four literatures indicated that there was significantly difference in adverse event rate between Voriconazole and amphotericin-B (P < 0.00 001); no significantly difference in adverse event rate between Voriconazole and amphotericin-B(P = 0.57); no significantly difference in adverse event rate between Voriconazole and Micafungin (P = 0.69); no significantly difference in adverse event rate between Voriconazole and Fluconazole (P = 0.70); Subgroup analysis indicated that adverse event rate between Voriconazole and Itraconazole is P=0.001, P = 0.17 respectively. Conclusion Voriconazole showed relative high efficient and low toxicity characteristics in treatment of malignant hematology accompanied by invasive fungal infection. But with its widely clinical application, the clinical value of Voriconazole needs to be further tested.

Objective To investigate left ventricular rotation in heahhy subj ects and patients with hypertrophy cardiomyopathy(HCM). Methods Twenty-five healthy subjects and 41 patients with HCM were enrolled. Two-dimensional standard echocardiography were performed and analyzed using Siemens Sequoia C512 system and velocity vector imaging 2.0 version. Left ventricular end diastollc volume(EDV).end systolic volume(ESV),left ventricular ejection fraction(LVEF),systolic peak rotation velockv and displacement of endocardium and epicardium of basal and apical part of left ventricle were measured.Difference of basal and apical rotation velocity and displacement between endoeardium and eDicardium(DVbase,DVape,DDbase,DDape) were calculated. Results Left ventricle rotated clockwise at basal part and counterclockwise at apex during systole. It rotated stronger at apex(P＜0.05 or P＜0.001)than at basal part and stronger in endocardium than in epicardium(P＜0.01 or P＜0.001). The rotation velocitv time curve consisted of a peak during systole and two peak during diastole,while the rotation displacementtime curve was composed of a smaller diastolic peak and a larger systolic peak. There was asvmmetricalhypertrophy at the basal part of HCM patients,and DVbase and DDbase were significantly increased(P＜0.01 or P＜0.001) in the significant hypertrophy segment. Conclusions Velocity vector imaging can assess left ventricular rotation effectively. HCM patients acquire mismatch of endocardium and epicardiuIn rotation.

Objective To assess the effect of ultrasound contrast agent SonoVue on the dimensions and systolic function of left and right ventricle in pigs. Methods Sixteen pigs were randomly assigned to two groups. Intravenous injection of 1 ml of SonoVue were given in study group, and repeated 20 min later. The control group was given the same doses of saline. Before and after the administration of contrast agent, the end-diastolic dimension (LVEDD, RVEDD). end-systolic dimension ( LVESD, RVESD) and fractional shortening(LVFS,RVFS) of left and right ventricle were measured. The time to reach the extreme value of these parameters and the time to return to the baseline were recorded. Results There was no significant difference regarding the parameters at baseline between the two groups. After injection of SonoVue,RVEDD significantly increased from (25. 88 ± 1. 38) mm at baseline to its maximum of (33. 26 ± 0. 99)mm( P < 0. 05). Accordingly,RVFS significantly increased from (26. 90 ± 1. 92) % to (33. 92 ± 2. 53) % ( P <0. 05). Meanwhile,LVEDD remarkably decreased from (38.10 ± 1. 39)mm at baseline to its minimum of (26.25 ± 0. 65)mm( P <0. 05) and LVFS remarkably decreased from (36. 24 ± 1. 93) % to (29.13 ± 3.00) % ( P < 0. 05). There was no change in the control group after administration of the saline. When SonoVue was given repeatedly, the maximum RVEDD and RVFS was (29. 98 ± 1. 23) mm and (31. 09 + 1.90) % , respectively, which had less increase compared to the first time. Minimum LVEDD and LVFS was (31. 91 ± 1, 64)mm and (32. 17 ± 2. 31)%,respectively,with less decrease compared with which at first injection. It took (10. 15±0. 59) min for the right and left ventricle to reach the extreme value and (9.00± 0. 56) min to return to the baseline at the first injection. The time used for the right and left ventricle to reach its peak change and back to baseline after second injection of SonoVue were shorter [(8.73± 0.55) min and (6.89± 0.43) min, respectively,both P <0.05]. Conclusions Administration of SonoVue was associated with acute, transient dilation of right ventricle and compression of left ventricle. The influence of SonoVue on the right and left ventricle became less at it second injection.

OBJECTIVETo detect the anti-FSH antibody using ELISA, and further probe into the role of anti-FSH in infertile patients.

METHODSThe anti-FSH antibody was detected using ELISA in the serum of patients with spermatogenesis dysfunction, of infertile patients with normal sperm density and motility, and of normal fertile males.

RESULTSThe positive rate of anti-FSH antibody in the patients with oligospermia and/or asthenospermia [22.4% (22/98)] was significantly higher than that in the normal fertile [4% (2/50)] (P < 0.05) and that in the infertile patients with normal sperm density and motility [6.7% (2/30)] (P < 0.05). The positive rate of anti-FSH antibody in the patients with oligospermia and/or asthenospermia was lower than that in the patients with azoospermia [54.5% (12/22)] (P < 0.05). There was no significant difference in the positive rate between the normal control and the sterile males with normal sperm density and motility.

CONCLUSIONThe anti-FSH antibody may be an important factor to cause spermatogenesis dysfunction by combining FSH to form immune compound and depress the activation of FSH.

Objective:To evaluate the correlation between inflammatory diet and reflux esophagitis (RE) with the dietary inflammatory index (DII), and to provide scientific evidence for the prevention and treatment of RE at the level of dietary guidance.Methods:From December 2021 to September 2022, 145 RE patients (RE group) who visited the First Affiliated Hospital of Xinjiang Medical University were recruited. During the same period, 145 subjects who underwent check-ups at the First Affiliated Hospital of Xinjiang Medical University were selected as the healthy control group, and age and gender were matched according to the ratio of 1 to 1. The baseline data of the 2 groups, including body mass index, the history of smoking and drinking, poor dietary habits, and physical activity intensity were collected. Dietary intake of the patients was assessed by a semi-quantitative food frequency questionnaire, and the overall DII was calculated to evaluate the potential anti-inflammatory or pro-inflammatory effects of diet. According to the tertiles of the DII of the healthy control group (33.3% and 66.7% as the cut-off), dietary inflammatory potential was divided into low (<-0.06), moderate (-0.06 to 1.11) and high pro-inflammatory potential diet (>1.11). Logistic regression model was performed to analyze the correlation between DII and RE risk. Linear trend test was used to compare the overall change trend of RE risk OR value along with the increase of DII. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:The body mass index of RE group was higher than that of healthy control group( (24.11±2.57) kg/m 2 vs. (23.38 ±2.60) kg/m 2), and the difference was statistically significant ( t=-2.41, P=0.017). The proportions of smoking, drinking, over-eating, and eating within 3 h before bedtime of RE group was higher than those of the healthy control group (42.8%, 62/145 vs. 31.0%, 45/145; 31.0%, 45/145 vs. 16.6%, 24/145; 33.1%, 48/145 vs. 17.9%, 26/145; 52.4%, 76/145 vs. 13.1%, 19/145), and the differences were statistically significant ( χ2=4.28, 8.39, 8.78 and 50.86, P=0.039, 0.004, 0.003 and<0.001). While the proportions of night snacking and moderate to severe physical activity of RE group were lower than those of the healthy control group (14.5%, 21/145 vs. 24.1%, 35/145; 22.8%, 33/145 vs.37.2%, 54/145), and the differences were statistically significant ( χ2=4.34 and 7.24, P=0.037 and 0.007). The DII of RE group was higher than that of the healthy control group (1.05 (0.03, 1.62) vs. 0.34(-0.61, 1.35)), and the difference was statistically significant ( Z=8 661.50, P=0.010). Compared with the low pro-inflammatory potential diet, high pro-inflammatory potential diet had a 1.30-fold increased the risk of RE ( OR=2.30, 95% confidence interval (95% CI) 1.29 to 4.09, P=0.005). After adjusting for total energy intake, age, gender, ethnicity, body mass index, education level, and physical activity intensity, the high pro-inflammatory potential diet was still positively correlated with the risk of RE ( OR=2.58, 95% CI 1.16 to 5.76, P=0.020). In the continuous DII, the risk of RE increased by 36% for each 1 increase in DII ( OR=1.36, 95% CI 1.11 to 1.68, P=0.003). After adjusting for major confounding factors, the continuous DII was still positively correlated with the risk of RE ( OR=1.41, 95% CI 1.08 to 1.85, P=0.012; OR=1.42, 95% CI 1.05 to 1.93, P=0.023). The results of trend test showed that the higher the DII, the greater the risk of RE ( P=0.039). Conclusions:Pro-inflammatory diet is correlated with the increased risk of RE, and there is a certain dose-response relationship. Reasonable reduction of the intake of pro-inflammatory food may be beneficial to reduce the risk of RE.
