Objective To observe the clinical efficacy of acupoint application in canicular days plus TDP radiation in treating primary dysmenorrhea due to cold-dampness.Method Eighty-three patients were randomized into group A of 32 cases, group B of 20 cases, and group C of 31 cases. Group A was intervened by acupoint application plus TDP, group B was by acupoint application alone, while group C was by oral administration ofTong Jing Bao granules. The Visual Analogue Scale (VAS) scores of the three groups were observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 93.1% in group A, versus 85.0% in group B and 77.4% in group C. The total effective rate of group A was significantly different from that of group B and group C (P<0.05). The total effective rate of group B was significantly different from that of group C (P<0.05). The VAS scores were changed significantly after treatment in the three groups (P<0.05). After treatment, the VAS scores of group A and B were both significantly different from that of group C (P<0.05).Conclusion Acupoint application plus TDP is an effective method in treating primary dysmenorrhea due to cold-dampness.

BACKGROUND:Previous studies from Shaanxi Institute of Ophthalmology have shown that ostrich cornea has the advantages to be developed into the alternatives of human corneal material.
OBJECTIVE:To determine the potential toxic effects of ostrich corneal stromal scaffold on cel s.
METHODS:Cel culture methods were used to culture L-929 cel s in the extracts of ostrich acel ular corneal
stroma which was dried and dehydrated. 3-(4,5)-Dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide assay was used to evaluate the growth and proliferation of cel s after cultured for 1, 2 and 3 days.
RESULTS AND CONCLUSION:After the cel s were cultured in the extracts of ostrich acel ular corneal stroma subjected to dryness and dehydration for 1, 3 and 5 days, and the toxicity level of cultured cel s was graded as level 1. The cytotoxicity test was conducted according to the“National Standard of the People's Republic of China GB/T16886.5-2003”. After cultured in the extracts of ostrich acel ular corneal stroma, a smal number of cel s were round in shape and loosely adherent without intracytoplasmic granules, and cel lysis could be observed
occasional y. The results of 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide assay showed that
the ostrich acel ular corneal stromal scaffold which was dried and dehydrated had level 1 of cytotoxicity and could be considered as a qualified material.

Aim To study the effect of bioactive compounds from paecilomyces tenuipes(BCPT) on antioxidization and lymphocyte proliferation in chronic unpredictable mild stress(CUMS) model of depression in rats.Methods Depression animal model was reproducted in CUMS,UV spectrophotometer analysis technique was used to detect the activity of SOD、GSH-PX and CAT,and content of MDA and NO in rat serum;lymphocyte proliferation was tested with MTT method.Results BCPT could obviously enhance the activities of SOD、GSH-PX and CAT,and also significantly inhibit the increase of MDA and NO content in serum in CUMS rats;BCPT decreased the serum from depressive rat inhibited ConA-induced lymphocyte proliferation.Conclusion BCPT produces an antidespressant-like effect in antioxidation and cellular immunological function in CUMS rats.

Aim To study the effect of bioactive compounds from paecilomyces tenuipes(BCPT) on AVP content of hypothalamus,pituitary and expression of AVP mRNA of hypothalamus and behaviour in chronic unpredictable stress model of depression in rats.Methods The depression animal model was induced by chronic unpredictable stress.The behaviour of rats was tested in the open field.The effect of BCPT on AVP content in hypothalamus and pituitary was tested by radioimmunoassay.RT-PCR was used to test the expression of AVP mRNA in hypothalamus.Results BCPT could decrease the expression of AVP mRNA of hypothalamus and decrease AVP content of hypothalamus and pituitary in chronic stressed rats obviously.BCPT could increase ambulation and rearing score of chronic stressed rats in the open-field test.Conclusion BCPT exhibited an antidepressant-like effect may in part be associated with the decreasing AVP content of hypothalamus and pituitary,and the expression of AVPmRNA of hypothalamus in chronic unpredictable stress model of depression in rats

AIM: To study the acute toxicity of bioactive compounds from paecilomyces tenuipes (BCPT) and the effect of BCPT on lipid peroxidation of brain in chronic stress model (CMS) of depression in rats. METHODS: The depression animal model was induced by chronic unforeseeable stress (CUS). The maximally tolerated dose (MTD) was used to detect the acute toxicity of BCPT. UV spectrophotometer analysis technique was used to detect the activity of SOD, GSH-PX and CAT, and content of MDA and NO in rat's brain. RESULTS: The MTD of BCPT was 9 g?kg -1 . BCPT could obviously enhance the activities of SOD, GSH-PX and CAT, and also significantly inhibit the increase of MDA and NO content in brain in CMS rats. CONCLUSION: BCPT has little toxicity and produces an antidespressant-like effect in antioxidation in CMS rats.

Aim Exploration of the effects of bioactive compound from paecilomyces tenuipes (BCPT) on the behavior, ultrastructure of hippocampus, and expressions of BDNF and Bax of cerebral cortex in CUS rats. Methods The depression model rat was induced by chronic unpredictable stress(CUS). The Open field test was used to observe the behavior of CUS rats. The expressions of BDNF and Bax of cerebral cortex were studied using immunohistochemical method, and average optical density of cortical neuron was calculated by image analysis. Morphology of hippocampus was observed by transmission electron microscope. Results Compared with model group, BCPT could obviously increase the activity of ambulation and rearing and the number of positive neuron of BDNF, decrease the number of positive neuron of Bax, and effectively prevent pathological damage induced by chronic unpredictable stress. Conclusion BCPT may exhibit the effects of antidepression, up-regulate the expression of BDNF, down-regulate the expression of Bax, and improve of the ultrastructure of hippocampus.

Objective To examine the expression levels of cyclin Dl in the patients with chronic myelogenous leukemia (CML), and evaluate the pathogenesis and clinical significance of cyclin Dl in CML Methods The real-time quantitative polymerase chain reaction (RQ-PCR) was performed to detect the expression levels of cyclin Dl in the bone marrow samples of 18 patients with CML, and 16 samples of benign hemopoietic patients. The relationship between the expression levels of cyclin Dl and the progression and prognosis of patients with CML were analyzed. Results The level of cyclin Dl was higher expressed in 18 patients with CML than the control group (P <0.001). The levels of cyclin Dl was apparently higher expressed in accelerated phase /blast crisis phase than in chronic phase (P <0.05). And the RQ-PCR method showed the tendency that a significant increase was observed in the levels of cyclin Dl from 0.1980 in control group to 1.4002 in chronic phase and 5.4540 in accelerated phase /blast crisis phase. Conclusion The cyclin Dl overexpressed in CML, the roles of cyclin Dl in CML might be an oncogene expressed. The expression level is correlated with the progression and prognosis of patients with CML.
