Two cases of special intracranial otogenic complications were analyzed in the aspects of clinical characteristics, diagnosis and therapy. We concluded that for patients with huge cholesteatoma which damaged the bone of skull base, or chronic otitis media patients with sharp deterioration in symptoms, accompanied by headache and fever, we should promptly do the enhanced magnetic resonance to avoid the missed diagnosis of intracranial complications.

Objective To probe into the clinical effect of acupuncture combined with herbal medicine with the functions of detoxication and purging fu-organ on patients with constipation of phlegm-heat and bowel-repletion type in acute cerebral infarction.Methods The enrolled cases were randomly assigned to an observation group of 35 cases and a control grouD of 35 cases.Besides both groups were treated with routine neurological treatment and acupuncture with the flinchon of brain activating,the observation group was treated by acupuncture combined with herbal medicine with the functions of detoxication and purging fu-organ and the control group was treated with Dilute Glycerol.Such indexes of patients in both groups were observed 7 days and 21 days before and after the treatment as clinical effect of constipation,scores of related symptoms,and scores of traditional Chinese medical category and clinical effect.Results The effective rates of eonstipation 7 davs and 21 days after treatment were 93.7% and96.9% in the observation group,and 61.8% and79.4% in the control group,with significant differences between the two groups(P<0.01).After the treatment for 7 days and 21 days,the symptoms of constipation.dark tongue,yellow and greasy fur were improved significantly in the observation group than those in the control group(P<0.05);The observation group also showed a definite therapeutic effect than the control group on treating the svmptoms of upset minded,constipation,red or dark tongue,yellow and greasy fur(P<0.01).The scores of traditional Chinese medical category of the observation group were lower than that of the control group(P<0.01)after treatment for21 days.The total improvement rate was 97.0% in the observation group comparing 55.8%in the control group,showing significant difference(P<0.01).Conclusion The method of acupuncture combined with herbal medicine with the functions of detoxication and purging fu-organ has a definite therapeutic effect on treating constipation of phlegm-heat and bowel-repletion in acute cerebral infarction.It can also improve clinical effects of these patients,which is worth generalizing in the clinical practice.

AIM: To study the effect of tissue kallikrein gene (HK) treatment on blood pressure in type 2 diabetic rats and its mechanism. METHODS: Male Wistar rats were injected with low dose streptozotocin and fed with diets enriched in fat and sugar to form type 2 diabetic model. Recombinant adeno-associated viral vectors (rAAV)-mediated HK gene (HK group) or LacZ gene (LacZ group) was introduced to the diabetic rats. The systolic blood pressure was measured every 2 weeks. The acetylcholine (Ach)-dependent vasodilation response, the synthesis of nitric oxide (NO), the expression of endothelin-1 (ET-1) and endothelin-A receptor (ET_A-R) in the aorta were detected. RESULTS: (1) Systolic blood pressure was significantly higher in diabetic rats than that in normal control rats. In HK group, systolic blood pressure was significantly reduced within 2 weeks after injection with rAAV?HK, reached near normal levels at 4 weeks and kept until the experiments ended (16 weeks). (2) In LacZ group, Ach-dependent vasodilation response of isolated aorta was markedly decreased than that in HK group (P

ObjectiveTo determine the cerebral protection effect and mechanism of propofol on global cerebral ischemia and reperfusion damage in rats.Methods19 adult male Wistar rats were randomly divided into 3 groups, ischemia group (n=7), propofol group (n=7), and sham injury group (n=5). Global cerebral ischemia and reperfusion model were made by means of Pulsinelli's method. Rats in propofol group were anesthesia with propofol at the dosage of 1.5 ml/h for 30 min at the beginning of reperfusion. Apoptosis and necrosis rate were detected by cytometry. In the same time, bcl-2, Bax and p53 protein expression in hippocampus neurons were detected. ResultsThe apoptosis and necrosis rate in propofol group were significantly decreased as compared with ischemia group ( P<0.05). Bax and p53 protein expression in hippocampus neurons were also significantly decreased as compared with ischemia group (P<0.05), however, no significant findings in bcl-2 protein expression (P>0.05).ConclusionPropofol can decrease apoptosis and necrosis rate in cerebral ischemia reperfusion injured neuron, and the mechanism maybe related to decreasing the expression of Bax, p53 protein.

To be a reference to industrial production of Chinese materia medica (CMM) and modernization of CMM and to summarize several relevant articles and consulte some publications about common key technologies in CMM production. Since 2000, some new technologies have been applied to CMM industrial production, such as SFE, macroporous resin extraction, MST, high-speed centrifugal, ultrasonic extraction, microwave extraction, HSCCC, etc. There are still some problems and difficulties lying in its application to industry. But with the innovation and further research of these new technologies, the application of these technologies to CMM preparation and production may help to expedite the modernization and industrial production of CMM. These technologies will be applied to CMM industrial production with making it more and more vigorous.

Objective To observe the therapeutically effect of kangnao liquid on Pi3k mRNA and Aktm RNA ex-pressions in rats with focal cerebral ischemia-reperfusion (I/R) injury. Methods 180 male SD rats were randomly divided into 6 groups:sham operated group, model group, three kangnao liquid groups (high-dose, medium-dose and low-dose) and nimodipine group. Rats in kangnao liquid groups were administrated with kangnao liquid of 24 g/(kg · d), 12 g/(kg · d) and 6 g/(kg · d), orally once a day. Rats in nimodipine group were given nimodipine 1 mg/(kg · d). Rats in model group and sham group were treated with the same volume of distilled water for 7 days. The animal model of middle cerebral artery occlusion (MCAO) was established by a monofilament method from right internal carotid artery. The neurological evaluation was per-formed 24 h after reperfusion. The in situ hybridization was used to investigate the expression levels of Pi3k mRNA and Akt mRNA in rats on 12 h, 24 h, 48 h, 72 h and 168 h after ischemia for 2 h. Results Compared with model group, neurological functions were improved significantly in kangnao liquid groups. The expression levels of Pi3k mRNA and Akt mRNA were al-so significantly higher in kangnao liquid groups than those of model group. The expression levels of Pi3k mRNA and Akt mRNA were significantly higher in nimodipine group than those of model group, but which were lower compared with those of high-dose and medium-dose kangnao liquid groups. Conclusion Kangnao liquid can protect nerve cells by enhancing the expressions of Pi3k mRNA and Akt mRNA in rats with cerebral ischemia-reprefusion injury.
