OBJECTIVETo explore relationship between effect of Lamivudine in the treatment of cirrhotic patients with uncompensated hepatitis B with hepatitis B virus (HBV)genotypes and HBV specific cytotoxic T lymphocytes (CTL).

METHODS80 cases of uncompensated cirrhotic hepatitis B (40 cases with genotype B and 40 with genotype C), HBV DNA positive, HBeAg positive and human leukocyte antigen (HLA)-A2 positive,were treated with Lamivudine 100 mg/d, one year later, its effect and relationship with HBV genotypes and HBV specific CTL were observed.

RESULTSHBV DNA turned negative:40 cases with genotype B turned negative (100%). In the 9th and 10th month of treatment, there was one case with genotype C had YMDD variation respectively and Adefovir dipivoxil was used for treatment, of the rest 38 cases, HBV DNA of 26 cases (68.42%) turned negative,HBV DNA negative rate of patients with genotype is lower than that of patients with genotype B, chi2 = 14.91, P < 0.01. HBeAg turned negative: 18 cases with genotype B (45%) turned negative, more than that of patients with genotype C (7 cases, 18.42%), chi2 = 6.32, P < 0.05. Peripheral blood HBV specific CTL level: before treatment, it was (0.33 +/- 0.03)% of patients with genotype B,higher than that of patients with genotype C [(0.11 +/- 0.02)%], t = 8.12, P < 0.001. 1 year after treatment: it was (0.44 +/- 0.04)% of patients with genotype B, higher than that before treatment, t = 4.01, P < 0.001, it was also higher than that of patients with genotype C 1 year after treatment [(0.23 +/- 0.03)%], t = 5.63, P < 0.01, alanine amino-transferase (ALT) returned to normal: 38 cases with genotype B (95%) returned to normal, more than that of patients with genotype C (28 cases, 73.68%), X2 = 6.79, P < 0.01.

CONCLUSIONEffect of Lamivudinein the treatment of cirrhotic patients with uncompensated hepatitis B is better in patients with genotype B than patients with genotype C, its mechanism may be related to lower level of HBV specific CTL in patients with genotype C than patients with genotype B.

【Objective】 To analyze the detection characteristics of a novel serum marker, hepatitis B core-associated antigen (HBcrAg), in the HBsAg-/HBV DNA+ blood donors in Wuxi. 【Methods】 A total of 37 previous HBsAg-/HBV DNA+ blood donors were followed up by telephone and their serum was obtained, and the serum of 22 HBsAg-/HBV DNA+ blood donors was detected by electrochemiluminescence and real-time PCR nucleic acid screening as the OBI group for HBcrAg enzyme-linked immunosorbent assay(ELISA). The serum of 20 healthy blood donors who underwent dual ELISA and one nucleic acid testing(NAT) was selected as the healthy control group, and the serum of 20 patients with chronic hepatitis B who were clinically diagnosed by Wuxi Fifth People's Hospital was selected as the experimental CHB group, and HBcrAg ELISA was detected respectively. The correlation analysis between HBcrAg and HBeAb, HBcAb, ALT and HBV DNA in the OBI group was performed. 【Results】 Thirty-seven blood samples were detected by chemiluminescence for HBsAg and NAT, and 22 HBsAg-/HBV DNA+ samples were detected in the OBI group, with a detection rate of 59.46%. The serum HBcrAg expression content (ng/mL) between the OBI group, the healthy control group and the CHB group were (0.92±0.13), (0.47±0.09) and (1.14±0.23), respectively, and the differences were statistically significant (P<0.05), the expression of HBcrAg in the OBI group and CHB group was higher than that in the healthy control group (P<0.05). There was no correlation between HBcrAg and HBeAb, HBcAb, ALT and HBV DNA indexes in the OBI group (P>0.05). 【Conclusion】 The expression of HBcrAg in the OBI group and CHB group was higher than that in the healthy control group, and the serum HBcrAg was not correlated with HBeAb, HBcAb, ALT and HBV DNA to a certain extent. HBcrAg has a good application prospect in screening HBsAg-/HBV DNA+ blood donors.

Objective:To investigate whether the therapeutic effect of Dahuang Mudan Tang on septic acute intestinal dysfunction in sepsis ratsis related to the regulation of expression of triggering receptor expressed on myeloid cells-1(TREM-1). Method:Totally 100 male SD rats were injected intraperitoneally with lipopolysaccharide (LPS) at a dose of 4.5 mg·kg^-1 to build sepsis model. The sepsis model rats were randomly divided into five groups:model group, glutamine group (3.75 g·kg^-1),low,medium, high-dose Dahuang Mudan Tang group(7.5,15,30 g·kg^-1),and another 10 normal rats were selected as normal group. Seven days later,2 mL suspension (100 mg lactulose and 50 mg mannitol) was orally administrated by gavage, and 24 h urinewas collected. The ratio of lactulose to mannitol in urine (L/M) was detected by HPLC with pulsed electrochemical detection (HPLC-PED).Serum citrulline concentrationsin blood and ileum were determined by HPLC.Enzyme linked immunesorbent assay (ELISA) was used to detect the concentrations of triggering receptor expressed on myeloid cells-1(TREM-1),tumor necrosis factor-α(TNF-α),intestinal fatty acid binding protein(iFABP) and D-lactic acid.Real-time PCR was used to detect the mRNA expressions of TREM-1,Toll-like receptors2(TLR2),Toll-like receptors 4(TLR4),myeloid cell differentiation protein(MyD88),nuclear transcription factor-κB(NF-κB).Electron microscopy was used to observe the pathological changes of intestinal mucosa injury. Result:Compared with normal group, the serum concentrations of TREM-1,TNF-α,iFABP, D-lactate; the ratio of lactulose to mannitol in urine (L/M)and the expressions of TREM-1,TLR2,TLR4,MyD88,NF-κB mRNA in model group were increased obviously(P<0.05,P<0.01); citrulline concentration was decreased obviously(P<0.05);the lengths of the villus and thicknesses of the mucosal layer were decreased obviously(P<0.05);the Chiu score was increased obviously(P<0.01).Compared with model group,the expressions of TREM-1,TLR2,TLR4,MyD88,NF-κB mRNA,and the serum concentrations of TREM-1 and TNF-α in all medication administration groups were decreased obviously(P<0.05), with no difference between these groups.Compared with model group, the serum concentrations of iFABP, D-lactate, L/M, the Chiu scorein glutamine group, medium-dose Dahuang Mudan Tang group and high-dose Dahuang Mudan Tang group were decreased obviously(P<0.05), lengths of villus and thicknesses of mucosal layers were increased obviously(P<0.05); and the citrulline concentrations were increased obviously(P<0.05). There was no difference between the three groups. Conclusion:Dahuang Mudan Tang can effectively treat SAID in rats, and its mechanism may be realized by regulating the expression of TREM-1 and relieving intestinal inflammation of intestinal tract.

Objective To investigate the seroprevalence of Toxoplasma gondii infection in patients with gynecological malignant tumors, so as to provide the evidence for the control of T. gondii infections in the patients with gynecological malignant tumors. Methods A total of 327 patients with gynecological malignant tumors were recruited, and 200 women with normal healthy examinations were served as controls. The serum anti-T. gondii IgG and IgM antibodies were detected by using ELISA, and the seroprevalence was compared between the patients and controls, and among various types of cancers. Results The overall seroprevalence of T. gondii was 26.91% (88/327) in the patients with gynecological malignant tumors, which was significantly higher than that (5.00%) in the healthy volunteers (χ² = 39.36, P<0.01) . The prevalence of anti-T. gondii IgG antibody in the cancer patients was significantly higher than that in the controls (26.30% vs. 5.00%; χ² = 37.79, P<0.01), while the prevalence of anti-T. gondii IgM antibody in the cancer patients was not significantly different from that in the controls (0.92% vs. 0; corrected χ² = 0.58, P > 0.01) . The positive rates of anti-T. gondii IgG antibody were 27.68%, 25.47% and 25.69% in ovarian cancer, cervical cancer, and breast cancer patients respectively, which were all significantly higher than those in the controls (χ² = 32.35, 27.32 and 28.00; all P values<0.01); however, there was no significant difference among the various types of cancer patients in the positive rates of anti-T. gondii IgG antibody (χ² = 0.17, P > 0.05) . In addition, the positive rates of anti-T. gondii IgM antibody were 1.79%, 0 and 0.92% in ovarian cancer, cervical cancer and breast cancer patients respectively, which was not significantly different from those in the controls (all P values > 0.05). Conclusions The seroprevalence of T. gondii infection is high in the patients with gynecological malignant tumors. It is suggested that the prevention and control of T. gondii infection should be strengthened in these patients.

OBJECTIVETo observe the anesthetic effect of combined superficial anesthesia and auricular point injection for nasal endoscopy surgery.

METHODSForty cases of grade I - II as ASA for nasal endoscopy surgery were randomly divided into a combined auricular point injection and superficial anesthesia group (group A) and a simple superficial anesthesia group (group B), 20 cases in each group. Both groups accepted superficial anesthesia 2 times on the bilateral nasal cavities with cotton pieces that was immersed in the mixed solution of 1% Tetracaine 30 mL and 0.1% Adrenaline 2 mL. In group A, bilateral auricular points of Shenmen and Waibi (externol nose) were injected with 0.1 mL Vitamin B1 solution before the superficial anesthesia. After 10 min of observation, surgery was carried out. During the surgery, the patients only accepted a small amount of vasoactive substance and Fentanyl according to the changes of patient's blood pressure, heart rate and pain feeling.

RESULTSThe total effective rate of 90.0% in the group A was significantly better than 75.0% in the group B (P<0.05). The rate of using analgetic and vasoactive substance in the group A was obviously less than that of the group B.

CONCLUSIONCombined auricular point injection and superficial anesthesia has good anesthetic effect for nasal endoscopy surgery.
