The practice and exploration of bilingual teaching for the course of microbiology has been made in order to improve the students foreign lingual level and to meet the higher requirement on tip-top person with the social development. As a result,bilingual teaching is welcome,and the teaching effect is so distinct that the aim was reached to either study the fundamental knowledge or enhance the English level.

OBJECTIVETo investigate the dynamics and clinical significance of serum hepatitis B virus (HBV) DNA levels during the terminal phase of acute-on-chronic liver failure (ACLF) with different hepatitis B e antigen (HBeAg) status.

METHODSOne-hundred-and-seven patients with terminal ACLF were tested for HBeAg status by electrochemiluminescence immunoassay and serum HBV DNA levels by real-time PCR at three chronological time ranges, representing increasing severity of disease phases prior to death (day 0): 29-56 d, 15-28 d, and 0-14 d.

RESULTSIn the 37 HBeAg(+) patients, HBV DNA levels at above-mentioned phases were 6.10+/-1.63, 5.61+/-1.50, and 5.29+/-1.96 log10 copies/mL. In the 70 anti-HBe(+) patients, HBV DNA levels were 4.63+/-1.82, 5.81+/-1.78, and 4.93+/-1.73 log10 copies/mL. Phase to phase comparisons revealed that the HBV DNA level in the HBeAg(+) group was significantly higher than that in the anti-HBe(+) group at 29-56 d (P less than 0.05), and that 15-28 d and 0-14 d were not significantly different (P more than 0.05). Intragroup comparisons of phases revealed no significant differences in the HBeAg(+) group (P more than 0.05), but a significant difference between 15-28 d and 0-14 d (P less than 0.05) for the anti-HBe(+) group.

CONCLUSIONSerum levels of HBV DNA in patients with HBeAg positivity are higher than those in patients with anti-HBe positivity as the disease phase of ACLF nears fatality. Following the deterioration to liver failure, the HBV DNA load in HBeAg(+) patients remains stable while that in anti-HBe(+) patients decreases.

OBJECTIVETo study the different features of hyperplasia in castrated and uncastrated mice after testosterone (T) treatment.

METHODSForty-eight BALB/c mice were randomly divided into 6 groups of 8 in each: castrated (A), uncastrated (B) , castrated + low T (C), uncastrated + low T (D), castrated + high T (E), uncastrated + high T (F). Groups C and D were treated with testosterone solution at the dose of 12.5 mg/(kg d) and Groups E and F at 125 mg/(kg d) for 20 consecutive days, while Groups A and B received saline only. All the mice were sacrificed on the 21st day, their ventral and dorsal prostate glands weighed and their pathological features studied.

RESULTSAtrophic prostates were observed in Group A, but normal in Group B; prostatic hyperplasia was found in both Group C and D, but more obvious in the latter (P <0.05); and a slightly higher degree of hyperplasia was noted in Groups E and F than in C and D. There was an increase in serum T and vascular endothelial growth factor (VEGF) concentration and a decrease in serum estrogen (E2) concentration in the testosterone treated groups.

CONCLUSIONBoth castrated and uncastrated mice develop prostate hyperplasia after short-term testosterone treatment, although in different degrees and with different features, which may help further the studies on the association of castration and androgen with prostate diseases.

OBJECTIVETo investigate the management of incidental prostate cancer after TURP by laparoscopic radical prostatectomy (LRP).

METHODSBetween April 2005 and December 2011, we treated 4 cases of incidental prostate cancer with p504s (+) by LRP, 1 at 3 mon, while the other 3 at 1.5 mon after TURP.

RESULTSThe operations were successfully performed in all the 4 cases, all by extraperitoneal approach. Postoperative pathology showed prostate cancer in 2 of the cases with Gleason scores of 6-7, high-level epithelial neoplasia in 1, and no malignancy in the other. Postoperative observation and 1-79 mon follow-up visit revealed good urinary function but no obvious urinary incontinence, metastasis and erectile dysfunction.

CONCLUSIONWith practiced laparoscopic skills, laparoscopic radical prostatectomy may achieve satisfactory results in the treatment of incidental prostate cancer after TURP.

In this paper, we designed to investigate the frequencies of tumor necrosis factor receptor 2 (TNFR2) polymorphisms at nt587 and nt694 in south Chinese SLE patients and healthy individuals and explore whether genetic variants in TNFR2 gene is involved in the pathogenesis of SLE. The results showed that the nt587G allele frequency was 21.1% in the 128 SLE patients and the allele frequency was 13.0% in the 135 healthy individuals, the former was significantly higher than the latter in the allele frequency (P ＜ 0.05). People with the nt587 G variant showed high risk to SLE. The frequency of nt694 was slightly but not statistically significantly increased in SLE patients compared with healthy controls(16.0% versus 11.9%, P= 0.149). These results indicate that the polymorphism at nt587 of TNFR2 is associated with the south Chinese SLE patients. The polymorphism at nt694 is not associated with SLE.

OBJECTIVETo investigate the expression and clinical significance of KiSS- 1 and E- cadherin in gastric cardia carcinoma and the correlation between the two proteins.

METHODSThe expression of KiSS- 1 and E- cadherin in 80 patients with gastric cardia carcinoma and 20 patients with normal gastric cardia epithelium was detected by immunohistochemical technique.

RESULTSThe expression of KiSS- 1 was negatively correlated with lymphatic metastasis and clinical stage (P < 0.05), but not correlated with the cancer differentiation (P < 0.05). The expression of E- cadherin was negatively correlated with lymphatic metastasis, clinical stage, and cancer differentiation (P < 0.05). Spearman test showed a positive correlation between KiSS- 1 and E- cadherin expression (r(s)=0.722, P < 0.05).

CONCLUSIONKiSS- 1 and E- cadherin may play important roles in inhibiting the invasion and metastasis of gastric cardia carcinoma.

OBJECTIVETo obtain allelic loss mapping and define the minimal lost region on chromosome 1q21 in gastric carcinomas, and explore role of 1q21 loss of heterozygosity (LOH) in the development and progression of gastric carcinogenesis.

METHODSUsing 7 high-density microsatellite markers and PCR method, lq21 LOH was analyzed in 30 paired specimens of fresh gastric carcinoma, and the relation between 1q21 LOH and the clinicopathological features of the malignancy was tested.

RESULTSThe LOH frequency on chromosome 1q21 from these gastric carcinoma tissues reached 60% (18/30). The LOH frequencies of the microsatellite markers D1S514, D1S2696, D1S498, D1S305, D1S2624, D1S2635 and D1S2702 were 13.3%, 10%, 20%, 23.3%, 33.3%, 40% and 23.3%, respectively. The minimal lost region on 1q21 LOH in the gastric carcinoma tissues was located in the region between D1S2624 and D1S2707, in the vicinity of D1S2635. No significant relations of 1q21 LOH to the patients' age, gender, location of the primary foci, clinical staging, or the tumor differentiation were noted (P>0.05), but 1q21 LOH was correlated to lymph node metastases of the malignancy (P<0.05).

CONCLUSIONHigher frequency of 1q21 LOH occurs in gastric carcinoma cells, suggesting the presence of potential tumor suppressor genes closely associated with gastric carcinogenesis near the region of D1S2635.

OBJECTIVETo detect changes of Foxp3 expression in the decidua in patients with preeclampsia and investigate the correlation of Foxp3-924 (rs2232365) polymorphisms with preeclampsia.

METHODSFrom October 2011 to December 2012, 252 normal pregnant women and 156 preeclampsia patients of Han nationality from the same geographic region were tested for Foxp3-924 genotypes by polymerase chain reaction with sequence-specific primer (PCR-SSP). Sixty-eight of the patients with preeclampsia (33 with mild and 35 with severe preeclampsia) and 30 of the normal pregnant women were also examined for Foxp3 expression in the decidua using immunohistochemical method.

RESULTSFoxp3 positive expression rates in the decidua was 51.52% in mild preeclampsia and 28.57% in severe preeclampsia cases, significantly lower than that in the control group (86.67%, P<0.05). In preeclampsia patients, the frequencies of Foxp3-924G/G, G/A, and A/A genotypes were 0.1346, 0.4615 and 0.4038, respectively, and the frequencies of Foxp3-924A and Foxp3-924 G were 0.6346 and 0.3654, respectively. The genotype frequencies of Foxp3-924G/G, G/A and A/A in the control group were 0.1508, 0.4087 and 0.4405, respectively, and the frequencies of Foxp3-924 A and Foxp3-924 G were 0.6448 and 0.3552, respectively. No significant differences were found in the gene frequencies of Foxp3-924G/A between preeclampsia patients and the control group (P>0.05).

CONCLUSIONThe expression level of Foxp3 in the placental tissue of preeclampsia patients is significantly lower than that in normal pregnant women, suggesting that lowered Foxp3 expression decreases the immunosuppressive function and causes imbalance of immune tolerance between maternal-fetal to induce preeclampsia. Foxp3-924 polymorphisms is not significantly correlated with the occurrence of preeclampsia.
