摘要： To study the efficacy of Fuganling granula (FGL, 复肝灵颗粒) in treating mouse immunological hepatic injury that was caused by Bacille Calmette Guerin (BCG) and lipopolysaccharide (LPS), a total of 60 mice were adopted, among which, 50 mice were given intraperitoneal injection with BCG and LPS to establish an immunological liver injury model and then were randomly divided into 5 groups (10 mice/group): 4 groups received treatment of FGL orally at the doses of 100 mg/kg (high-dosage), 50 mg/kg (middle-dosage), 25 mg/kg (low-dosage) and bifendate orally at the dose of 80 mg/kg, respectively. One group was treated with distilled water orally. The remaining 10 mice were given distilled water intraperitoneally as the normal control group. The indices of thymus, liver and spleen, and the activities of the alanine aminotransferase (ALT), aspartate aminotransferase (AST) in the serum were detected. Compared to the normal rat, the model group’s thymus index decreased significantly. The liver index and spleen index increased significantly. The activities of serum ALT and AST increased significantly (all < 0.01). Compared to the model control group, the group treated with FGL in high-dosage, middle-dosage or low-dosage can decrease the activities of ALT and AST and the group treated with FGL in high-dosage and middle-dosage can increase the thymus index significantly ( < 0.01). This experiment established the immunological liver injury model successfully and found that FGL has a remarkably protective effect on this kind of immunological hepatic injury.

A meta-analysis of randomized trials of maintenance bacillus Calmette-Guerin instillation efficacy against

《医学前沿（英文）》 2008年 第2卷 第3期   页码 259-263 doi: 10.1007/s11684-008-0049-3

摘要： Meta-analysis was used to determine whether maintenance intravesical bacillus Calmette-Guerin (BCG) could reduce recurrence after transurethral resection of tumor 1 grade 3 (T1G3) superficial bladder cancer. All available published data of randomized clinical trials comparing transurethral resection plus intravesical BCG to either resection alone or resection plus another treatment on the treatment results in patients with superficial bladder cancer of T1G3 were selected for analysis. Both the fixed effects model and random effects model were applied, and the odds ratio () with its 95% confidence interval (CI) was used as the effect size estimate. Sensitivity analysis and publication bias determination were performed by funnel plots and comparing s of different models. Within the follow-up period, 375 of 915 (41.0%) BCG-treated patients and 332 of 733 (45.3%) non-BCG-treated patients developed tumor recurrence. In the combined results, a statistically significant difference in the s for tumor recurrence between the two treatment groups was found (randomized model combined effect 0.58, 95% CI 0.41 to 0.83, = 0.003). The stratified meta-analysis did not show any statistically significant confounding effects on the results when stratified by BCG strains. The randomized model combined effect of Pasteur F and other strains were 0.50 (95% CI 0.26 to 0.95, = 0.04) and 0.63 (95% CI 0.40 to 0.99, = 0.04), respectively. Therefore, we came to the conclusion that adjuvant maintenance instillation BCG combined with transurethral resection of bladder tumor (TURBT) is an effective conservative treatment for preventing recurrence of T1G3 bladder cancer.

Study of recombinant human IFN-α-2b bacilli Calmette–Guerin activated killer cells and against bladder

摘要： Presently, one of the most potent immunotherapies is the application of bacillus Calmette Guerin (BCG) to prevent recurrences of the superficial bladder cancer. Despite its successful use, nonresponders and certain side effects remain a major obstacle. Therefore, current studies aim at developing recombinant BCG (rBCG) strains secreting Th1-like cytokines to improve the effectiveness of the therapy. In this study, a new type of rBCG strain constructed by Tianjin institute of Urology was tested for its immunostimulatory capacity . Peripheral blood monocytes (PBMC) were stimulated by recombinant BCG and transformed into bacilli Calmette–Guerin activated killer (BAK) cells, and the effect of anticancer BAK cells was studied. Recombinant IFN--2b-BCG, wild-type BCG (wBCG), wild-type BCG and IFN--2b were coincubated with PBMCs respectively , and the proliferation of PBMC was detected with MTT in different time. BAK cells have the ability to kill bladder tumor cells, and the antitumor activity of effecter cells was determined by LDH release assay. The result of MTT showed that the proliferation of PBMC in the recombinant BCG group was more powerful than in the other two groups (<0.05). The result of LDH release assay showed that the antitumor activity of BAK cells stimulated by Recombinant BCG was the highest in all groups. We conclude that the recombinant BCG can activate more PBMCs to anti-bladder cancer than wild-type BCG does.

Can intravesical bacillus Calmette-Guérin reduce recurrence in patients with non-muscle invasive bladder

null

《医学前沿（英文）》 2014年 第8卷 第2期   页码 241-249 doi: 10.1007/s11684-014-0328-0

摘要：

Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer (NMIBC). NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guérin (BCG) instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.

Testing of tuberculosis infection among Chinese adolescents born after terminating the Bacillus Calmette

摘要：

The prevalence of tuberculosis infection among adolescents born after terminating the Bacillus Calmette–Guérin (BCG) booster vaccination in China was estimated using tuberculin skin testing (TST) and QuantiFERON-TB Gold assay (QFT) to investigate the influence of neonatal BCG vaccination on the performance of TST. Data analysis was conducted for 2831 eligible participants aged 5–15 years from the baseline survey of a population-based multi-center prospective study. The prevalence rates of TST (induration≥10 mm) and QFT positivity were 9.3% (264/2827) and 2.5% (71/2831), respectively. The rate of QFT indeterminate result was 2.2% (62/2831). The overall agreement between TST and QFT was low (concordance= 88.0%; κ coefficient= 0.125). Only TST was positively associated with BCG vaccination with an adjusted odds ratio of 1.71 [95% confidence interval, 1.26–2.31]. A history of close contact with patients of active TB was significantly associated with positivity for TST and QFT. Our results suggested that BCG neonatal vaccination still affects TST performance, and a two-step approach might be considered for TB infection testing among adolescents in China.
