Chinese Journal of Postgraduates of Medicine 2016;39(12):1060-1063
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.

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 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 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 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.
