Objective To investigate the effects of cyclophosphamide(CTX) on proliferation and morphology of human alveolar rhabdomyosarcoma cell-line PLA-802 xenografted tumor in nude mice.Methods Sixteen nude mice which had been implanted PLA-802 by subcutaneous injection into the right armpit were divided into control group(5 mice),normal saline group(5 mice) and 20 mg/kg CTX group(6 mice).They were given CTX or normal saline intraperitoneally once every two days,starting on the 7~(th) day after tumor cell transplantation.Tumor volumes were measured every two days for drawing the growth curve.Animals were anesthetized on the 26~(th) day after tumor cell transplantation to get weight and specimens of the tumors.Specimens were stained of HE or EM,and then examined with light microscope and electron microscope.Results The proliferation of xenografted tumors was inhibited significantly(P

Through textual research of the literature on tiny collateral and perforator vessel, the two concep- tions were compared and the similarity was analyzed in terms of definition, anatomical level, quantity, the flow of qi and blood and clinical application, etc. It is considered that the tiny collateral in Neijing (Inner Canon of Yellow Emperor) and the perforator vessel of modern medicine are different names of one physical structure. It is proposed that the combination of the tiny collateral theory of CM and the research findings of perforator vessel of western medicine would deepen the understanding of the tiny structure of human skin and promote the development of both TCM and modern medicine.

Objective: To observe the expression of Notch1 and Smad4in colorectal carcinoma and their clinical significance. Methods: Immunohistochemistry staining was used to detect the expression of Notch1 and Smad4 in 51cases of colorectal carcinoma. Results:(1) The expression of Notch1 in colorectal carcinoma was higher than that in the normal tissue(P0.05),except histological grading and pathological types of patients(P0.05),except Dukes stage,lymph node of metastasis and pathological types of patients (P

Fulminant Clostridium difficile colitis (FCDC) means severe Clostridium difficile colitis (CDC), which often manifested with severe diarrhea, fever, abdominal distention, electrolyte disorder, hypoalbuminemia, and it can lead to pseudo membrane colonitis, toxic megacolon, bowel perforation, septic shock, and multiple organ dysfunction. Now Clostridium difficile (CD) becomes one of the most important medical institutions related infectious pathogens. In particular, the recently discovered mutant CD strain NAP1/BI/ribotype 027 has high pathogenicity in the global epidemic and its outbreak. The morbidity and mortality of FCDC has a significant upward trend in the global in recent years. All broad spectrum antimicrobials usage is considered to be the primary risk factor for the onset of FCDC. Therefore, FCDC has become a new challenge for clinical work. The epidemiology, related risk factors, pathogenesis, diagnosis, severity classification, recent progress in clinical treatment of FCDC were reviewed in order to provide help for clinical treatment of FCDC and related research.

The improvement of HAMD, NIHSS and BI scores in the observation group were significantly better than those in the control group, the difference was statistically significant (P<0.05). Conclusion ChaiHuShuGan Decoction has synergistic effect with Group cognitive behavioral therapy in the treatment of PSD can significantly improve the symptoms of depression and neurologic impairment, and can improve the quality of life of patients.

Objective To investigate the characteristic and optimal therapy of critical limb ischemia (CLI) caused by limb arteriosclerosis obliterans (ASO) in elderly patients ≥70 years. Methods The clinical and follow-up data of 122 elderly patients (≥ 70 years) with CLI caused by ASO were analyzed. The differences were compared between 70-79 years patients (67 cases) and 80- 91 years patients (55 cases). Results The time from onset to treatment in 80-91 years patients was significant longer than that in 70-79 years patients:(45 ± 15) d vs. (26 ± 10) d, the ratios Rutherford class 4-6 and Trans-Atlantic Inter-Society Consensus (TASC) Ⅱclass C-D lesions in 80-91 years patients were significantly higher than those in 70-79 years patients: 89%(49/55) vs. 67%(45/67) and 91%(61/67) vs. 100%(55/55), and there were statistical differences (P<0.01 or<0.05). The ankle arm index (ABI) after endovascular treatment in 70-79 years patients (37 cases) and 80- 91 years patients (22 cases) were significantly higher than those before treatment: 0.86 ± 0.05 vs. 0.40 ± 0.05 and 0.85 ± 0.05 vs. 0.39 ± 0.08, and there were statistical differences (P<0.05). There were no statistical differences in ABI of conservative treatment patients before and after treatment (P>0.05). The conservative treatment mortality in 80- 91 years patients was significantly higher than that in 70- 79 years patients: 29%(7/24) vs. 9%(2/23), and there was statistical difference (P<0.05). Ninety-five patients were followed up for 1-24 months, and the median was 15 months. Nine patients (7%) died within 30 d. In the first year of follow-up, 8 cases underwent amputation, 6 cases died, and 6 cases had stent thrombosis. In the second year of follow-up, 12 cases underwent amputation, and 18 cases died. The median survival time was 19 months. The mortality in conservative treatment patients was significantly higher than that in endovascular treatment patients:53%(19/36) vs. 24%(14/59), and there was statistical difference (P<0.05). The survival time in amputation patients had increasing trend, but there was no statistical difference (P>0.05). Conclusions The≥70 years elderly patients with CLI caused by ASO have more complications and longer time from onset to treatment, and the lesions are mainly Rutherford class 4-6 and TASC classⅡC-D. Endovascular treatment is difficult, but the effect is better than conservative treatment.

A lot of children with congenital heart disease have an abnormal development of nervous system. A variety of biochemical and physical examination indices can be used to predict adverse outcome of neurodevelopment caused by congenital heart disease and they contribute to early intervention and improvement of neurodevelopmental disorders. In recent years, new progresses in the laboratory tests, neurological physiccal examination and perioperative management of the neurodevelopmental abnormalities caused by congenital heart disease have been made. The predictive factors of abnormal neurodevelopment caused by congenital heart disease were reviewed in this article.
