Objective To investigate the alterations of SHP-2 mRNA of thymus cells of mice with ? ray-induced leukemia. Methods BALB/c mice were randomly divided into canceration group, non-canceration group, and control group. The gene mutation and content of SHP-2 mRNA in thymus cells were detected by PCR-SSCP, DNA sequencing, and real time fluorescence quantitative PCR (FQ-PCR). Results PCR-SSCP showed there was gene mutation within 700～1 096 bp of SHP-2 mRNA in thymus cells of mice in the canceration group, which was not supported by DNA sequencing. No significant difference in change of SHP-2 mRNA content was found in thymus cells in canceration, non-canceration, and control groups. Conclusion There is translational abnormality of SHP-2 mRNA in thymus cells of mice with ? ray-induced leukemia, which is presented as translational enhancement.

Objective To investigate the effects of Xuebijing injectio (Chinese herb preparation) on intestinal function and inflammatory responses in severe burn patients. Method Thirty-two patients with comparable severity in burn injury were randomly divided into Xuebijing injectio treatment group (n = 16) and control group (n = 16). Patients in both groups received routine burn therapy, while those in Xuebijing treatment group additionally received Xuebijing injectio 100mL in intravenous drip twice a day for 7 days. Before the treatment and on the 3rd and the 7th day after the treatment, blood concentrations of diamine oxidase (DAO), lipopolysaccharide (LPS) ,tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were determined in both groups. Analysis was made by SPSS 12.0 software. Results The plasma levels of DAO, LPS, TNF-α and IL-6 were decreased in both groups after the treatment. However, the plasma levels of DAO, LPS, TNF-α and IL-6 in the Xuebijing treatment group were significantly lower than those in control group on the 3rd and 7th day after the treatment (P＜ 0.05).Conclusions Xuebijing injectio could protect intestinal function, decrease the plasma level of endotoxin and lessen zhe inflammatory responses in severe burn patients.

Objective To further investigate the pathohistology of chronic gastritis in children and the relationship between helicobacter pylori(Hp) infection and mucosal chronic inflammatory.Methods Gastric antrum biopsies were carried out from children who had chronic gastritis confirmed by gastroendoscopy during the past 3 years in our hospital.The results of pathohistological observation were analyzed by retrospectire method.Results One thousand six hundred cases of chronic gastritis were included,in which 1007 cases without Hp infection,593 with Hp infection.Among the patients without Hp infection,mild inflammatory were much more than mode-(rate) or severe inflammatory(86% vs 14%).Although,in patients with Hp infection,mild inflammatory were the most common presentation(63%),moderate and severe inflammatory were more predominant in patients with Hp infection.The degree of inflammatory was increased with the quantity of Hp infection.The ratio of lymphocytes,neutrophils and lymphoid follicles in gastric mucosa was much higher in Hp positive group than negative one(94%,40%,22% vs 60%,11%,5%,respectively),and the difference was significant in statistic analysis.Gastric mucosal atrophy was found more in Hp positive group(16.5%) than negative one(7%).The proportion of intestinal metaplasia in cases with Hp infection was 1.5% compared with 0.1% in these children.Conclusion The study shows that there is a close relationship between Hp and antrun chronic inflammation and mucosal atrophy.
