Objective To package the recombinant lentivirus containing HIV-1 Vpr gene and detect the effect of Vpr protein expression on the latent infection and lyric replication of KSHV.Methods The fragment of Vpr gene from expression plasmid pCI-neo-Vpr was cloned into the lentivirus vector pHAGE-CMV-MCS-IzsGreen,then the recombinant plasmid pHAGE-Vpr,package vector psPAX2 and envelope vector pMD2.G were cotransfected into 293T cells.GFP expression was observed by fluorescent microscopy.Culture media of 293T cells were harvested and filtered through 0.45 μm filter.After 293T cells were infected by a series of diluted lentivirus,the virus titer was checked by observing GFP expression.Vpr mRNA transcripts in 293T cells were detected by RT-PCR.Then BCBL-1 cells were infected by the recombinant lentivirus with 1 MOI,GFP expression was observed by fluorescent microscopy,and the mRNA transcripts and protein expression of Vpr in BCBL-1 cells were detected by RT-PCR and Western blot.Meanwhile,the mRNA transcripts and protein expression of KSHV lytic cycle gene Rta were detected by RT-PCR and Western blot,respectively.Results The recombinant lentivirus carrying HIV-1 Vpr was packaged successfully with the virus titer of 4 × 107 TU/ml.After infected with lentivirus,BCBL-1 cells could express GFP,and the exact band of Vpr was detectable by RT-PCR and Western blot.Moreover,the expression of KSHV Rta mRNA and protein were downregulated by Vpr protein.Conclusion Overexpression of HIV-1 Vpr mediated by the recombinant lentivirus could inhibit KSHV lytic replication and enhance KSHV latent infection.

Methods : On the basis of major drying condition, such as duration of drying, temperature of drying, evaluating different drying technology; On the basis of the quantity of the powder sticking on the wall and the hygroscopicity of one, investigating different excipients how to affect the spray drying. Seeking the optimum kinds and quantity of excipients. Results : The best properties of the granules are from the spray drying process. ?-cyclodextrin and lactose have the effects on solving the powder sticking on the wall. Conclusion : The spray drying process is the optimum one. Adding 3～5 percent of ?-cyclodextrin has an effect on improving the phenomenon of powder sticking on the wall in process of the spray drying.

Background:Pancreatitis is the main complication of ERCP,and a variety of risk factors will increase its risk. Studies showed that temporary pancreatic duct stent can reduce the incidence of post-ERCP pancreatitis (PEP). Aims:To study the efficacy and safety of prophylactic pancreatic duct stenting on preventing PEP in patients with risk factors. Methods:Patients undergone ERCP and accompanied with one or more PEP-associated risk factors from November 2013 to November 2016 at Huaibei People's Hospital were enrolled,and were divided randomly into pancreatic duct stenting group (observation group)and non-stenting group (control group). Serum levels of amylase at 4,24 and 48 hours after the procedure and incidence of PEP were compared between the two groups. Results:A total of 297 patients were enrolled, and 147 patients were in observation group,and 150 patients in control group. No significant differences in gender,age and ERCP disease spectrum were found between the two groups (P > 0. 05). Incidence of PEP was significantly decreased in observation group than in control group (6. 1％ vs. 16. 0％,P < 0. 05). Serum levels of amylase at 4,24 and 48 hours after the procedure were significantly decreased in observation group than in corresponding control group (P < 0. 05), however,no significant difference in incidence of hyperamylasemia was found between the two groups (59. 2％ vs. 54. 7％, P > 0. 05). Conclusions:Prophylactic pancreatic duct stenting may decrease the incidence of PEP in patients accompanied with PEP-associated risk factors, especially could decrease the severity of PEP. However, the incidence of hyperamylasemia is not decreased.

Objective To study the relationship between advanced liver fibrosis and peripheral neuropathy in patients with type 2 diabetes mellitus (DPN). Methods A total of 173 patients (89 men and 84 women) with type 2 diabetes who hos?pitalized in Tianjin Third Central Hospital within nearly three years (2013.02-2015.02) were divided into three groups ac?cording to non-alcoholic fatty liver disease (NAFLD) fibrosis score:group A (NFS≤-1.455), group B (-1.455

Abstract: Fifteen novel ligustrazine-tetrahydroisoquinoline derivatives were designed and synthesized according to the association principle of pharmaceutical chemistry. The structures were identified by IR, NMR and ESI-MS. The inhibitory activities of platelet aggregation induced by ADP and AA have been measured by Bron method. Preliminary pharmacological results showed that compounds 7g, 7h and 7n had potent inhibitory activity against platelet aggregation induced by AA, and the compound 7o showed significant inhibitory activity against platelet aggregation induced by ADP.

The plague occurs due to the long-term persistence of Yersinia pestis in natural environment.During the period of plague epidemic and quiescence,there are still some unknown scientific questions,such as where Yersinia pestis preserved,which mode preserved,and which mechanism caused plague epidemic.Thus,the researches on the preservation and viability of Yersinia pestis in every ecological element of plague natural foci will contribute to find the pattern for the occurrence and spread of plague.

Objective To investigate the relationship between plasma soluble CD36 (sCD36) and nonalcoholic fatty liver disease (NAFLD) in patients combined with type 2 diabetes mellitus (T2DM). Methods Plasma levels of sCD36 were determined in normal control group (group A, n=39), patients of T2DM without NAFLD group (group B, n=39) and T2DM with NAFLD group (group C, n=59). Liver fat content (LFC) and nonalcoholic fatty liver fibrosis score (NFS) were calculated in group C. Glucose and lipid metabolic parameters, liver function parameters and inflammatory parameters were also detect?ed in all three groups. Variance analysis was applied to analyze the differences of the above parameters among three groups;Correlation analysis was used to analyze the relationship between sCD36 level and all the above parameters;Multiple step? wise regression analysis was applied to determine the influencing factors of sCD36 level in patients of group C. Results Plasma sCD36 (μg/L) levels in group B (3.87 ± 1.16) and group C (5.72 ± 1.79) are higher than that of group A (2.57 ± 0.93) (both P<0.01), and it is higher in group C than in group B (each P<0.05);Correlation analysis showed that sCD36 level was positively correlated with body mass index (BMI), waist, visceral adipose tissue,fast insulin (FINS), insulin resistance in?dex (HOMA-IR), free fatty acid (FFA), alanine transaminase (ALT), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), LFC and NFS (P<0.01 or P<0.05);Multiple stepwise regression analysis showed that FFA, LFC, TNF-αand IL-6 were in?fluencing factors of sCD36 level in patients of group C. Conclusion Plasma sCD36 level was related to fatty liver severity, liver injury and fatty liver fibrosis, it might be used as a plasma marker of T2DM combined with NAFLD. CD36 might con?tribute to the development of T2DM combined with NAFLD through inflammatory mechanisms.

Objective: To evaluate the accuracy and clinical value of fractional lfow reserve (FFR) determined by CT coronary angiography (CTA) in relevant patients. Methods: A total of 43 patients treated in our hospitals from 2013-10 to 2015-10 were retrospectively studied. There were 29 (67.40%) with male gender, the average age was (60.2±10.1) years. The patients received CTA at 1 week prior coronary angiography (CAG), the interval between CTA and CAG was (5.4±1.6) days. FFR was measured by both CAG and CTA (FFRCT) in selected target vessel which was deifned as maximal diameter reduction 50% to 70%. The imaging data were recorded and compared, FFRCT was calculated. Results: 48 vessels from 43 patients were eligible for analysis as target vessels. FFRCT vas evaluated based on the gold criteria of FFR. FFRCT had the diagnostic accuracy at 83.3%, sensitivity 75.0%, speciifcity 89.3% and positive predictive value was 83.3%, negative predictive value was 83.3% respectively. FFR and FFRCT showed obvious correlation (r=0.704,P<0.001); Bland-Altman analysis presented good concordance with 95% limits of agreement for FFRCTand FFR value ranged from -0.12 to 0.16, and 95.8% of the points (46/48) fell in the 95% limit of agreement, Receiver operating characteristic curve indicated that AUC of FFRCT was 0.871 (95% CI 0.770-0.973). Conclusion: CTA could accurately assess FFR, and FFRCT might be used in guiding the treatment for patients with intermediate coronary stenosis in clinical practice.
