Objective To investigate the effect of two kinds of drainage operation including incision and drainage of abdominal operation and percutaneous puncture and drainage operation under ultrasound guidance on the short-term curative effect, mortality and complications risk in patients with single giant bacterial liver abscess. Methods Eighty patients with single giant bacterial liver abscess were selected, and all patients were treated with conventional therapy. Among them, 40 patients underwent incision and drainage of abdominal operation (control group), and 40 patients underwent percutaneous puncture and drainage operation under ultrasound guidance (observation group). The short-term curative effect, operation time, time of returning to normal body temperature, time of returning to normal white blood cell, hospitalization time, mortality and incidence of postoperative complication were compared between 2 groups. Results There were no statistical differences in total effective rate and mortality between control group and observation group: 92.5%(37/40) vs. 97.5%(39/40) and 5.0%(2/40) vs. 7.5%(3/40), P>0.05. The operation time, time of returning to normal body temperature, time of returning to normal white blood cell and hospitalization time in observation group were significantly lower than those in control group:(44.52 ± 5.68) min vs. (98.59 ± 12.70) min, (3.25 ± 0.74) d vs. (4.86 ± 1.32) d, (5.20 ± 1.35) d vs. (7.42 ± 1.79) d, (16.94 ± 3.61) d vs. (25.52 ± 5.28) d. The incidence of postoperative complication was significantly lower than that in control group:10.0%(4/40) vs. 27.5%(11/40), and there were statistical differences (P<0.05). Conclusions Two kinds of drainage operation in the treatment in patients with single giant bacterial liver abscess possesses the same clinical efficacy for short-and long-term curative effect; but percutaneous puncture and drainage operation under ultrasound guidance application can efficiently alleviate the clinical symptoms and signs, accelerate the recovery process of disease and be helpful to reduce the risk of postoperative complications.

Objective: Insulin glargine is a new long-acting basal insulin analogue.Glimepiride is an anti-diabetic drug with action independent of the pancreas.In this study,the efficacy and safety of glargine plus glimepiride in the treatment of elderly diabetic patients were evaluated.Methods: Sixty-five elderly diabetic patients were randomly assigned to receive Neutral protamine hagedorn insulin(NPH) plus glimepiride(n=19),and glargine plus glimepiride(n=21).The dose of insulin was adjusted according to the fasting blood glucose(FBG) level,with the target FBG

In this study,we constructed 2 eukaryotic expressing plasmids namely pcS2?S and pFP,encoding HBV preS2+S envelope protein and human IL 2/IFN ? fusion protein, respectively. The double plasmid fusion protein was used as an adjuvant in preparation of a treatment type HBV gene vaccine. To investigate its feasibility for use as a therapeutic DNA vaccine, we've evaluated the immune response after injection into healthy mice, HBV transgenic(Tg) mice, New Zealand rabbits and Rhesus monkeys. The results showed that the therapeutic DNA vaccine can improve: (1)the CTL activity; (2)the HBsAg(30?g/ml) specific T lymphocyte proliferation in which the stimulation index(SI) and cytokines(IL 2/IFN r) release levels of the pS2.S immunized group(SI=5.6?0.9; 226.3?41.1/51.1?7.1pg/ml) were significantly higher( P

The peptides from HBV cytotoxic T lymphocyte(CTL) epitope were used to either stimulate or impact the immune effector (E) or CTL target (T) cells respectively, in order to investigate the cellular immune response induced by DNA vaccination in both healthy and HBV transgenic (Tg) mice. It was found that HBV DNA based immunization could induce CTL activity in healthy BALB/c mice, with intensity correlated with the E/T ratio and IFN ? secretion level in its supernatants. The target cells hit by HBsAg CTL epitope peptide(pp20) could be lysed by the active CTL induced by HBV DNA vaccine encoding preS2 and HBsAg, while the cell lysis could not be observed in the target cells impacted by the HBcAg CTL epitope peptide (pp10). The supernatant IL 12 secretion level (211 3?39 8pg?ml -1 ) in the DNA vaccination group was significantly( P

Objective To investigate the efficacy of high-dose ambroxol in elderly patients with aspiration pneumonias. Methods Totally 62 patients aged 65 years and over with aspiration pneumonia were enrolled into 2 groups:conventional-dose group intravenously given ambroxol 60 mg/d (n=30) and high-dose group received 270 mg/d (n=32).The times of remission and fever disappearance,rate of adverse effects,average duration of hospitalization,rates of mortality and recurrence within 2 months were observed. Results There were no significant differences in clinical charecteristics between the two groups.The times of remission and fever disappear ance and average duration of hospitalization were lower in high-dose group than in conventional-dose group [(3.2±0.6)d,(54.2±19.5)h,(12.7±4.1) d vs.(3.8±1.1)d,(66.5±18.4)h,(13.5±3.1)d,t=2.11,2.36,2.04,all P＜0.05].No differences were found in rates of mortality and recurrence within 2 months between the two groups (6.3％,3.1％ vs.10.0％,13.3％,x2=0.01,0.87,both P＞0.05).Adverse effects did not appear in the two dose groups. Conclusions High-dose ambroxol is efficient and safe for aspiration pneumonia in elderly patients.

Objective To investigate the roles of Arsenic Trioxide to the lupus nephritis in MRL/ lpr mice and the effect on the expression of TGF-pl in the renal tubule. Methods 45 MRL/lpr mice were chosen for such experiment, then separated in 3 different groups, including arsenic trioxide ( ATO) group, cyclophosphamide (CYC) group and sodium chloride (NS) group. Urine of these mice was kept after the treatment to detect the urine protein levels. The pathological changes and the expression of IgG were observed , and the complement 3 of the nephridial tissue as well as the TGF-pl were detected by immunohisto-chemistry. Result The levels of urine protein in ATO group and CTX group were lower than NS group after the treatment ( P <0.05). The expression of IgG along the glomerular mesangium and capillary loop in ATO and CTX groups was less than NS group ( P <0.05). The expression of C3 had no significant difference within three groups ( P > 0.05). The glomcrulus spherulous cells and the integral of activity in ATO group and CTX group were less than that in NS group ( P <0.05). TGF-β1 wildly presented in the epithelial cells endochylema of the nephric tubule, but it was rarely seen in glomcrulus in NS group. The expression in the nephric tubule of ATO group was less than NS group (20.28 ± 1. 90 vs 68. 23 ± 2. 87, P < 0.01) , and the expression in the nephric tubule in CTX group was less than that in NS group (23. 26 ± 1.71 vs 68. 23 ±2. 87, P <0. 01). Conclusion TGF-pl may take part in the immunopathogenesis of lupus nephritis in MRI/lpr mice. ATO can relieve the inflammation of nephric tubule by down regulation the expression of TGF-β1. ATO can also relieve the tissue damage of kidney in lupus nephritis through reducing the inflammation of glomcrulus and interstitial substance,as well as the expression of the immunocomplex.

Objective To study the effect of periodontitis on rats with chronic bacterial prostatitis. Methods A total of 80 male rats were randomly divided into the 4 weeks group (n=40) and the 8 weeks group (n=40), and then the two groups were randomly divided into the normal control group (N=10), the periodontitis group (PE=10), the chronic bacterial prostatitis group (CBP=10), and the peri-odontitis+chronic bacterial prostatitis group (CBP+PE=10) respectively. The pathological changes, inflammation score, level of TNF-αand IL-1β, and indicators of periodontal of all rats were observed. Results In the 4 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no significant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score,TNF-αlevel ,IL-1 β level in CBP+PE group and CBP group were higher than that in N group and PE group (P<0. 05), while there was no sing-nificant difference between N group and PE group as well as between CBP+PE group and CBP group (P>0. 05). In the 8 weeks group, the indicators of periodontal in PE group and CBP+PE group were higher than that in N group and CBP group (P<0. 05), but there was no sig-nificant difference between PE group and CBP+PE group as well as between the N group and the CBP group (P>0. 05). The pathological changes, inflammation score, TNF-α level , IL-1 β level in CBP +PE group and CBP group were higher than that in N group and PE group (P<0. 05),while there was no singnificant difference between N group and PE group (P>0. 05). The pathological changes, inflam-mation score,TNF-α level ,IL-1 β level in CBP+PE group were higher than those in the CBP group (P<0. 05). Compared between 4 weeks group and 8 weeks group, there was no obvious difference in N group in terms of periodontal indexes. Periodontal indexes in 8 weeks PE group was higher than that in 4 weeks PE group (P<0. 05), but there was no significant difference prostate tissue pathology, inflamma-tion score,TNF-α level,IL-1βlevel (P>0. 05). Pathology, inflammation score,TNF-αlevel, IL-1βlevel in 8 weeks CBP group were low-er compared to 4 weeks CBP group (P<0. 05), and there was no significant difference between the indexes of periodontal (P>0. 05). Prostate tissue pathology, inflammation score, TNF-αlevel, IL-1βlevel in 8 weeks CBP+PE group were lower than that in 4 weeks CBP+PE group (P<0. 05), but indicators of periodontal in 8 weeks CBP+PE group were higher than 4 weeks CBP+PE group (P<0. 05). Conclusion Chronic bacterial prostatitis combined with periodontitis can inhibit self-healing tendency of chronic bacterial prostatitis of rats and keep rats in chronic inflammatory phase.

Objective To investigate the effect of DRAM1 on the acute ischemic injury of H9C2 cardiomyocytes. Methods H9C2 cardiomyocytes were treated with Oxygen-glucose deprivation (OGD) after DRAM1 adenovirus transfection. MTT assay was performed to detect cell viability and Annex V/PI staining was used to analyze the cell apoptosis. Western blot was performed to measure the expression of P62. Results DRAM1 overexpression increased the H9C2 cardiomycytes viability after OGD treatment for 12 hours. DRAM1 overexpression was attenuated, while siRNA-AD-DRAM1 exacerbated the apoptosis rate of H9C2 cardiomycytes after OGD treatment for 12 hours by Annex V/PI staining. P62 protein expression was increased in the H9C2 cardiomycytes after OGD treatment for 12 hours, which was reversed by DRAM1 overexpression. Conclusion DRAM1 may protect H9C2 cardiomycytes against OGD injury due to the improvement of the autophagy flux.

Objective:To investigate the effect of DNA vaccine expressed Helicobacter pylori(Hp) oipA on protecting against Hp infection.Methods:The ORFs of Hp oipA had been inserted into the eukaryotic expressing vector pVAX1 and SGC-7901 cells had been transfected with recombinant plasmid pVAX1-oipA. The expression of oipA had been detected by RT-PCR and ELISA. After extracted and purified, pVAX1-oipA had been injected into BALB/c mice through muscles of right leg one time each week for three weeks(100 ?g each mouse). pVAX1 blank and normal saline had been used as the control groups. Titer of antibodies had been detected by ELISA two months after the last immunization. Based on the confirmation of immunological response in the pVAX1 groups, mice had been given orogastric challenged with live Hp Sydney strain three times(0.5?108/0.5 ml each mouse). Four weeks after challenge, mice had been sacrificed. Histological change and the colonization of Hp in the gastric mucosa had been detected by urease test, the culture of Hp, and electronic microscopy.Results:SGC-7901 cells transfected with pVAX1-oipA had expressed corresponding production at the level of transcription and translation. Immunized mice had been induced anti-oipA antibodies. After challenged with bacterium, as contrast to immunized mice groups injected with pVAX1-oipA, pVAX1 blank, normal saline, the positive rate of urease test of gastric mucosa was 0(0/10), 90%(9/10), 100%(5/5)respectively,the positive rate of cultures of Hp was 20%(2/10), 90%(9/10), 100%(5/5)respectively. Histological findings: the different degree of erosion had been observed in control group, but 80%(8/10)of gastric mucosa were normal in immunized mice.Conclusion:oipA DNA could induce effective immune response in protection against Hp infection.
