Methods TCM medical information dtatabase and electronic medical system in Zhejing Province TCM Hospital from January 2010 to December 2015 were retrived. According to inclusion and exclusion criteria, leukemia patients’ materials that met the critiria were screened. The total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and cost of blood transfusion were set as costs, while white blood cell count, hemoglobin concentration, and platelet count were set as effectiveness indicators for cost effectiveness analysis. Results In patients with low white blood cell count increased unit white blood cell count, patients with high white blood cell count declined unit white blood cell count, patients with low hemoglobin increased unit hemoglobin count and patients with low platelet count increased unit platelet count, the total hospitalization fees, cost of Western medicine, the cost of Chinese patent medicine, cost of TCM decoction pieces, and blood transfusionfor the above increases showed a decreasing trend. Conclusion Health economics advantages in three blood routine indicators after treatment of integrated traditional Chinese and western medicine for leukemia is increasing year by year.

Objective To establish a flow cytometric measurement of detecting minimal residual disease(MRD) according to the leukemia-associated immunophenotypes in children with acute lymphoblastic leukemia(ALL) and to explore the significance of MRD detection in ALL children for a individualized treatment. Methods A variety of four-color fluorescent antibody combinations were used to investigate the children's normal bone marrow. The normal bone marrow pattern at two-parameter plots was established to identify the residual tumor cells, seventy-five bone marrow samples from newly diagnosed ALL children were analyzed with four-color cytometry to determined the optimal combinations which can clearly distinguish the tumor cells from normal cells. The bone marrow samples were monitored with the combination panel in 60 patients at the end of induction therapy and follow-up treatment. Cytomorphology test, PCR amplification of 29 fusion genes as well as IgG and TCR gene rearrangements were performed simultaneously. Results Sixty-nine cases (92.0%) could be identified for effective antibody combinations to monitor MRD by four-color cytometry. Fusion genes or IgG and T cell receptor (TCR) gene rearrangements can be detected in 21 cases (28.0%) to monitor MRD by PCR. No MRD can be detected in 25 bone marrow samples at the end of induction therapy and follow-up treatment. Four-color cytometry could detect as low as 0.021%-4.130% residual leukemia cells. Conclusion MRD can be monitored by flow cytometry which is faster than PCR, and the sensitivity is superior to morphology method.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

OBJECTIVETo investigate the role of the extracellular signal-regulated protein kinase 1/2 (ERK1/2) pathway in erectile dysfunction (ED) caused by the absence of testosterone (T).

METHODSWe randomly divided 30 eight-week-old healthy male SD rats into groups A (control) , B (castration), and C (castration + androgen replacement). The rats in groups B and C were castrated surgically, and those in C injected with T undecanoate (100 mg/kg) at 1 week after castration, while the others with 0.9% normal saline instead. At 1 month after treatment, we determined the serum T level, intracavernous pressure (ICP), and mean carotid arterial pressure (MAP) of the rats, and detected the expressions of ERK1/2 and endothelial nitric oxide synthase (eNOS) by Western blot.

RESULTSThe serum T level was significantly lower in group B ([1.27 ± 0.48] nmol/L) than in A ([17.14 ± 1.07] nmol/L) and C ([16.24 ± 1.90] nmol/L) (P < 0.05), and so were ICP and MAP (P < 0.05). The expression of ERK1/2 showed no statistically significant differences among the three groups (P > 0.05), that of phosphatase ERK1/2 was markedly higher while that of eNOS remarkably lower in group B than in A and C (both P < 0.05).

CONCLUSIONAndrogen replacement may improve the erectile function of castrated rats by regulating the ERK1/2 pathway.

Objectives To investigate the bacterial pathogens and their antibiotic resistance in children with pneumonia in Suzhou area. Methods Sputum specimens of 8179 hospitalized children with pneumonia from October 2005 to September 2011 were collected by sterile negative pressure aspirator and then cultured. The incidence of positive bacteria was tested by Kirby-Bauer method and broth dilution method, and their antibiotics resistances were analyzed. Results A total of 2391 of 8179 children were infected with positive rate of 29.23%. A total of 2552 strains of bacteria were detected with Streptococcus pneumoniae (42.40%), Haemophilus inlfuenzae (14.81%), Moraxelle catarrhalis (11.01%), Staphylococcus aureus (8.50%) and Escherichia coli (5.02%) as the most common strains. The infection rate of different bacterium was related to age, season and the type of pneumonia (all P<0.001). The tendency of antibiotic resistances in 2 140 bacterial isolates was found increased by the susceptibility test. Conclusions Streptococcus pneumonia and Haemophilus inlfuenzae are the most common bacterial pathogens in children with pneumonia in Suzhou area. The positive rate of different bacterium was related to age, season and the type of pneumonia. Attention must be paid to the rational use of antibiotics to reduce drug resistance.
