OBJECTIVE: To study the hemostatic effects of Qishu gongxue granules. METHODS: Kunming mice and Wistar rats were randomly divided into five groups, i.e. normal control group, Fuke zhixuening group and Qishu gongxuening granules high-dose, medium-dose and low-dose groups. The change of coagulation time was compared among five groups. The value of PT and APTT were determined. Platelet aggregative function in rats was detected. RESULTS: Qishu gongxuening granules could reduce coagulation time of model mice and the level of PT and APTT in rats while it enhanced platelet aggregative function in rats. CONCLUSION: Qishu gongxuening granules can reduce coagulation time and it can be used for uterine bleeding. Hemostatic mechanism is associated with the production of plasmozyme and thrombokinase in the coagulation of blood and platelet aggregative function.

Objective To investigate the effects of 8Hz infrasound on spatial learning ability of rats and its the underlying mechanism. Methods Forty male SD rats were randomly divided into a control group and an experiment group (consisting of the 8Hz, 90dB, 100dB and 130dB subgroups). The experimental subgroups were exposed to 8Hz, 90dB, 100dB or 130dB infrasound for 2 hours daily, respectively, for a total of 6 days. All of the rats were taken out of the infrasonic depot once a day and given Morris maze training. And at last the brain of the rats were harvested and treated with immunohistochemical staining for detection of ryanodine receptor (RyR). The content of RyR in hippocampi and temporal cortex were detected under an optical microscope. Results The rats in the 8Hz, 90dB, 100dB and 130dB subgroups showed prolonged latency in Morris training ( P =0.010, P =0.001 and P = 0.000 ). The hippocampi and temporal cortex of rats in 8Hz, 90dB, 100dB and 130dB subgroups showed less positive neurons of RyR ( P =0.000). There was a negative correlation between the latency period of rats finding the hidden platform and the content of RyR in hippocampus and temporal cortex. Conclusion Infrasound of 8Hz, 90dB, 100dB and 130dB could decrease the spatial learning ability of rats, and this was possibly related to the reduce of RyR in hippocampus and temporal cortex.

Objective To study the effect of 8Hz infrasound on the expression of 5-HTR of hippocampus and temporal cortex in rats. Methods SD rats were exposed to 8Hz, 90dB,100dB or 130dB infrasound, respectively for 2 hours daily. Then the rats' brains were taken and given stained immunohistochemically for (5-hydroxy tryptamine receptor,5-HTR). The content of 5-HTR in hippocampus and temporal cortex were detected under an optical microscope. Results The animals in the infrasound groups had less expression of 5-HTR in hippocampus and temporal cortex, and the least were at the 35th day for 90dB group and 100dB group and the 28th day for 130dB group (P

OBJECTIVE:To investigate the utilization of antineoplastic drugs and adjuvant drugs in our hospital. METHODS: By a retrospective review, the consumption quantity, consumption sum, and constituent ratio of antineoplastic drugs and adjuvant drugs used in our hospital from 2005 to 2008 were analyzed statistically. RESULTS: The consumption of antineoplastic drugs and assistant drugs had dominated the front places from 2005 to 2008, representing 25.91%, 28.16%, 31.16% and 33.00%, respectively of the total western drugs in terms of consumption sum, assuming a year-on-year increase tendency over the 4 years. Injections took a higher proportion, making up for 75.40%, 79.80%, 80.50% and 78.12%, respectively over the 4 years. The application of antineoplastic drugs and assistant drugs from domestic manufacturers assumed a predominant place. CONCLUSION: It is still necessary to standardize the use of antineoplastic drugs and assistant drugs in our hospital so as to ensure their safety, effectiveness and economy in clinical medication.

Objective To invesitgate the relationship between 8-iseprostane (8-iso-PG) level in exhaled breath condensates (EBCs) and severity of asthma and explore the role of 8-iso-PG in asthma evaluation and monitoring.Methods Fifty-nine patients with asthma were enrolled.In which 15 eases were acute exacerbation, 13 eases were mild intermittent, 15 eases were mild persistent, and 16 eases were mederate-to-severe persistent.Thirteen healthy volunteers were recruited as control.EBCs were collected using EeoSereen system.The 8-iso-PG levels in EBCs were measured by a specific enzyme immunoassay.The patients with mild intermittent asthma were treated with inhaled corticosteroid (ICS) for one month and their EBCs were recollected for 8-iso-PG measurement.Results Exhaled 8-iso-PG levels were obviously increased in the patients with acute asthma compared with those chronic asthmatics [(47.2±6.8) pg/mL vs (24.5±12.0) pg/mL, P < 0.01].In the chronic persistent asthma, the levels were significantly higher in patients with mild persistent and moderate-to-severe asthma [(17.9±1.2) pg/mL and (39.7±4.0) pg/mL, P <0.01].While 8-iso-PG level did not differ significantly in intermittent asthma [(13.5±1.1) pg/mL] compared with the control subjects (P > 0.05).After one-month ICS treatment the 8-iso-PG level in the patients with mild intermittent asthma did not change significantly although the ACT score improved.Conclusions 8-iso-PG levels in EBC are associated with the severity of asthma,implicating 8-iso-PG may be useful in monitoring airway oxidative stress in asthma.ICS treatment is incapable of decreasing the 8-iso-PG,suggesting the ICS has minor impact on oxidative stress.

Objective To investigate the prevalence of excessive daytime sleepiness and explore the associated factors in university teachers and staffs in Kunming.Methods Epworth sleepiness scale was used as the tool of diagnosis. We consecutively collected the data of teachers and staffs on duty in Yunnan Nationalities University,Yunnan Agricultural University,Yunnan Normal University,Kunming Medical University and Yunnan University of Finance and Economics within 8 months.Results The prevalence of excessive daytime sleepiness in university teachers and staffs was 12.45%, the prevalence of male was 16.82% and female was 7.70%, respectively. The results of Logistic regression showed that the main associated factors of excessive daytime sleepiness were male (OR=1.898),age (30 years and less was as control group,the ORs of 31-40 year group, 41-50 years group and more than 51 years group were 1.480, 2.366 and 2.719, respectively), family history of snoring (OR=3.371), consumption sedative (OR=1.815), memory failing (OR=2.044), dizzy and feeble (OR=2. 076),choking (OR=2.143),report apnea (OR=2.684),etc. Conclusions The prevalence of excessive daytime sleepiness is high in the university teachers and staffs that can partially represent the residents of Kunming city. The associated factors of excessive daytime sleepiness hint that excessive daytime sleepiness may be caused by sleep apnea/hyperpnoea syndrome in the sample population,hence the people with excessive sleepiness need further sleep monitoring .

Objective To study the preventive effect of paeonol on restenosis after angioplasty in rabbit balloon injury model and its mechanism.Methods Male New Zealand white rabbits with clean grade were selected.Balloon injury rabbit abdominal aorta combined with high cholesterol diet were used to establish rabbit atherosclerosis model.We used balloon to dilate the narrow abdominal aorta.The animals were randomly divided into four groups (control group,low concentration paeonol group,high concentration paeonol group and rapamycin group).Animals in different group were orally given normal saline 2 ml · kg-1 · d-1,low concentration of paeonol 75 mg · kg-1 · d-1,high concentration of paeonol 150 mg · kg-1 · d-1,rapamycin administrated with 1.25 mg · kg-1 · d-1 for six weeks respectively.After 6 weeks,the animals were killed by air embolism,and immediately dissected to remove the abdominal aorta.We used hematoxylin and eosin(HE) staining and Masson staining to detect the thickness of the arterial intimal hyperplasia and the gross morphological changes of the narrow artery.Immunohistochemical staining was used to detect changes of proliferating cell nuclear antigen (PCNA) expression level.Western blotting was used to discover P27kip1 protein expression in the narrow artery.Results Paeonol and rapamycin reduced the degree of intimal hyperplasia.The neointima areas in the control group,low concentration paeonol group,high concentration paeonol group and rapamycin group were (0.16±0.03),(0.09±0.01),(0.05±0.01) and (0.04±0.01) respectively; the ratio of neointimal area to media area was (90.62 ±3.43),(42.30 ±2.94) (33.72±3.19) and (28.78±6.67) respectively; the intimal area proliferation rate was (33.3 ± 3.1) ％,(23.2 ± 2.2) ％,(17.5 ± 1.5) ％ and (16.2 ± 1.7) ％ respectively.There were significant differences in the neointima area,ratio of neointimal area to media area,and the intimal area proliferation rate among the four groups (F=47.98,257.25,74.60,all P＜0.05).The expression level of PCNA and P27kip1 protein were (0.20±0.04),(0.06±0.02),(0.05±0.02) and (0.08± 0.02),and (0.47±0.09),(0.78±0.20),(1.29±0.12) and (1.83±0.13) in the control group,low concentration paeonol group,high concentration paeonol group and rapamycin group respectively,and the differences were statistically significant between the four groups (F=37.22 and 107.69,both P＜0.01).Conclusions Paeonol plays a role in anti-vascular smooth muscle cell proliferation.This effect may be through inhibiting the expression of PCNA,and increasing the expression of P27kip1 in the cell cycle.
