All patients were treated with routine therapy, including prozac and psychological therapy. Patients in the treatment group were also given Xiaoyao powder. Scores of Hamilton Depression Scale (HAMD), modified Barthel index (MBI) and Scandinavian Stroke Scale (SSS) of all patients were evaluated before and after therapy.ResultsAfter treatment, the effective rate and MBI scores were significantly higher and scores of HAMD and SSS were significantly lower for patients of the treatment group compared with those of the control group (P<0.01).ConclusionXiaoyao powder combined with prozac and psychological therapy can improve depression and neural function of PSD patients significantly.

Objective To explore the role and their relationship of Ki-67, VEGF and p27 expressed in adult patients with acute leukemia. Methods The expression of Ki-67, VEGF and p27 in bone marrow mononuclear cells (BMMNC) were analyzed by immunocytochemical staining, and their correlations of Ki-67, VEGF and p27 were statistically analyzed. Results The expression of Ki-67(42.48±25.78)% or VEGF (44.89±24.01)% on BMMNC from acute leukemia cells was significantly higher than that in the control (11.40±9.94)% or (16.90±12.54)% (P<0.01). But the expression of p27 (23.65±13.30)% was significantly lower than that in the control (50.23±22.68)% (P<0.01). The expressions of Ki-67 were positively correlated with and VEGF in patients with acute leukemia were positively correlated(r=-0.666, P<0.01), and the expressions of Ki-67 and p27 were negatively correlated with p27 in patients with acute leukemia (r=-0.316, P<0.05).Conclusion The evaluation of expression of Ki-67, VEGF and p27 on acute leukemic cells provides new insights to the pathogenesis is helpful in mechanism and is helpful in the diagnosis of acute leukemia.

Objective To investigate the early-pathologic changes in children′s antrum infected with different types of Hp and study the Hp isolate′s pathogenic.Methods The serum types of CagA and VacA from Hp were determined by Westen-Blot in 70 patients with Hp positive and 36 patients with Hp negative.The standard of gastritis pathologic classification was accordance with that of international made in Sydney. The pathogenic of Hp affecting was evaluated by the degree of inflammation, severity of active gastritis,lymph follicles and atrophy.Results The detection rate of type Ⅰwith high virulence in Hp isolates was 68.1%,mid-type isolates was 27.7% and type Ⅱ with low virulence isolates was 4.2%.To observe the pathologic distinction in 49 patients with type Ⅰisolate,20 patients with mid-type isolate and 3 patients with type Ⅱ isolate,the type Ⅰ and mid-type isolates had significant difference in inflammation and their activity in either antrum or duodenal ampulla.Three patients with type Ⅱ isolate have not active gastritis.Type Ⅰand mid-type isolates had significant difference in lymph follicles,and the lymph follicles caused by type Ⅰwere significant higher than those caused by mid-type.But there were no significant differences in intestinal metaplasia and atrophy.Conclusions TypeⅠisolate with high virulence is the main detection isolate of children infected by Hp in our district.There is inflammation occurrence in antrum specimens in childhood who infected with Hp.

Objective To prepare lipid-coated ultrasound microbubbles containing 10-HCPT(HLM) and explore the antitumor effects on mice xenografed H22 solid tumor using the technique of ultrasound-mediated HLM destruction. Methods Sixty-four tumor-bearing mice were radomly divided into A and B groups. Each group was divided into four groups again and administered respectively by tail vein with HI.M, non-drug-loaded microbubbles,10-HCPT and saline once a day. Ultrasound irradiation was applied on the tumor sites immediately after injection. After 7 days of consecutive treatment, all mice in group A were sacrificed and the tumors were harvested to measure weights. The tumor inhibition rate was calculated by weights. The tumor microvessel density (MVD) was detected by immunohistochemical staining. The tumor growth curve was depicted according to volumes. The survival time of mice in group B was recorded. Results The tumor inhibition rate was the highest in HLM group while this group's MVD was the lowest. Survival time in HLM group and 10-HCPT group were obviously longer compared with the control group,while no statistic difference was observed between the two groups. There was no statistic difference between the group of non-drug-loaded microbubbles and the control group. Conclusions Ultrasound irradiation mediates HLM destruction so that the drug is released from the vihicles at the same time, which can significantly enhance the tumor inhibition effect of 10-HCPT on the H22 tumor. This technique is expected to be adopted as a novel tool for liver cancer chemotherapy.
