AIM: To observe the influence of Toufengyu Dropping Pill(Rhizome chuanxiong,Radix angelicae dahuricae,etc) on neuropeptide and vasoactive substances in rat's migraine model. METHODS: Rat's migraine model caused by nitroglycerin were given Toufengyu Dropping Pill and rat's behavior and blood levels of NO,CGRP,ET,TXB_2 and 6-keto-PGF_(1a) were measured. RESULTS: The experimental results showed that Toufengyou Dropping Dill could obviously decrease rat's positive reaction number,the blood levels of NO,CGRP,TXB_2 and 6-keto-PGF_(1a),and increase the blood plasma level of ET,and rectify the imbalance of ET/NO ratio. CONCLUSION: Toufengyou Dropping Pill can affect the contents of neurotransmitter,neuropeptide in rat's migraine,then decrease the algoenic and inflammatory substances,relieve the neurogenic inflammation,and increase the pain threshold value,finally be quite effective for migraine.

Objective To observe the changes of SS activity and regulation of GH surrounding cerebral hemorrhage and the hypothalamus,and explore the disorder of SS GH to the affect of local neuronal internal circumstances in stress.Methods With intracerebral hemorrhage model in rats, SS GH content in the hypothalamus and cerebral hemorrhage periphery was determined using the radioimmunoassay.Results The SS content in the hypothalamus far from hematoma and the area surrounding cerebral hematoma elevated obviously, and reached its peak along with the hematoma content,meanwhile the GH content of relevant area trended to upregulate remarkably too.Conclusion While the SS content in the hypothalamus and the area surrounding cerebral hematoma elevated, the GH content of relevant area trended to rise remarkably too, the phenomenon indicated the stress disorder of SS GH axis during the highest peak of hematoma.

The application of cerebrovascular intervention brings the diagnosis and treatment of cerebrovascular disease into a brand-new domain. Many neurological physicians have become physicians of cerebrovascular intervention by training. In the big teaching hospitals carrying out cerebrovascular intervention, advanced physicians are the hard strength in the lot of cerebrovascular intervention. The training aiming at cerebrovascular intervention and comprehensive abilities affects both the training results and the therapeutic results of cerebrovascular intervention. Therefore, it is an important issue to explore how to consummate and standard the training methods of advanced physicians studying cerebrovascular intervention.

Objective:To investigate Intraflagellar Transport 80 (IFT80) protein expression in bone, lung, pancreatic, stomach, in-testinal, prostate, breast, and ovarian cancers to explore its mechanism in cancer cell proliferation and to diagnose and identify new tar-gets in cancer treatment. Methods:Immunohistochemistry was used to investigate the expression of IFT80 in gastric cancer tissue of different stages and in eight other kinds of human cancer tissues. We studied the relationship between cancer cell proliferation and inhi-bition of IFT80. Immunofluorescence method and cell culture were used to study the cilia and IFT80. Results:Results showed the fol-lowing:a) the expression of IFT80 was high in gastric and lung carcinoma tissues, moderate in breast and colorectal cancers, low in bone and ovarian cancers, and nearly absent in prostate and pancreatic cancers;b) inhibition of IFT80 in the A549 cancer cell line accel-erated cell proliferation and resulted in shorter, lower quality cilia;and c) IFT80 was abundantly expressed in cancer tissues of well-dif-ferentiated stage-IIA gastric cancer and normal gastric tissues, but was hardly expressed in late-stage, poorly differentiated gastric can-cer. IFT80 could have various degrees of expression in gastric carcinoma of other stages and differentiation. Conclusions:Different can-cer organs showed variation in IFT80 expression. IFT80 can be distributed in the organs with mechanical motion function, such as lungs and stomach. IFT80 is distributed on the cell cilia and can adjust the number and length of the cilia by reducing IFT80 protein ex-pression. Through a variety of ways, IFT80 directly or indirectly participates in the proliferation of cancer cells. Thus, the lowest or nearly zero expression of IFT80 can be seen in cancer tissues of high-grade malignancy, such as advanced cancers with poor differentia-tion.

Objective: To provide some experience and help for the pharmaceutical care for drug-induced acute kidney injury through analysis and pharmaceutical care performed by clinical pharmacist for two cases of drug-induced acute kidney injury. Meth-ods:Clinical pharmacist analyzed the mechanism of drug-induced acute kidney injury, provided some suggestions for the medication, helped doctors select hormone drugs reasonably and performed medical education in the patients. Results:The kidney function of the two patients was recovered during the hospitalization after the reasonable treatment and care by doctors and pharmacists. Conclusion:The drug-induced acute kidney injury should be paid high attention, and the medical education should be strengthened in the patients.

Objective To evaluate the regional cerebral metabolic changes in different episodes by magnetic resonance spectroscopy (MRS) after explosive brain injury in rabbits. Methods Fortyfive New Zealand white rabbits were randomly divided into eight groups, ie, normal control group( 10 rabbits) and trauma group (35 rabbits). The explosive injury in trauma group was induced by explosion of 600 mg TNT equivalent of paper detonators at 6.5 cm above the rabbit brain. The rabbits in trauma group was divided into 1,6, 12, 24 hours, 3, 7, 14 days subgroups (6 rabbits per group). The survival rate was observed at different time points after explosive injury. The MRS was used to detect the regional cerebral metabolic changes including N-acetylaspartate (NAA)/creatine (Cr) ratio and choline(Cho)/Cr ratio as well as evolution of blast injuries over time. Results The rabbits survived for overseven days in the trauma groups, with typical brain contusion manifested by pathological and conventional MRI. Compared with the normal control group, the NAA/Cr ratio was markedly decreased at one hour after injury, slightly rose again at 24 hours and fell again after seven days. The Cho/Cr ratio was markedly increased at one hour after injury, slightly fell again at 12 hours and rose again at three days after injury.Conclusions MRS can manifest the regional cerebral metabolic changes of rabbits with explosive injury at different time points and hence provide a theoretical basis for understanding the local tissue changes and determining the type of tissue damage after blast injury.

Objective To investigate the association between aortic calcification and risk of vertebral fracture in Chinese postmenopausal women.Methods This study recruited 561 postmenopausal women aged 60 or older who were prospectively followed for 3 years.Based on the ACS,the patients were divided into aortic calcification group (n =236) and non-aortic calcification group (n =325).Extent of aortic calcification and incidence of vertebral fracture were quantified on the baseline lateral radiographs of lumbar spine.Dual energy x-ray absorptiometry was utilized to evaluate the bone mineral density (BMD).Cox proportional hazards models were used to assess the associations between aortic calcification and risk of vertebral fracture.Results In aortic calcification group incidence of vertebral fracture was significantly higher than that in non-aortic calcification group (P ＜ 0.01).Moreover vertebral fracture presented an increased incidence while the ACS was higher.After the adjustment of age,body mass index,BMD,current smoking,current drinking,hypertension,diabetes,total cholesterol,myocardial infarction,stroke and 25-hydroxy vitamin D,aortic calcification with ACS ＞ 6(HR =3.03,95％CI 1.42-6.24),BMD (HR =2.82,95％ CI 1.75-5.68),age (HR =1.96,95％ CI 1.38-4.52),history of two or more falls (HR =1.45,95％ CI 1.24-2.79) and adiponectin (HR =1.07,95％ CI 1.22-2.31) were associated with increased risk of vertebral fracture.Conclusion Severe aortic calcification is closely associated with vertebral fracture for postmenopausal women.

Objective To explore the effect for nerve regeneration with immunosuppresssant FK506 a-round the cut after end-to-side neurorrhaphy of peripheral nerve. Methods There were 40 adult SD rats and were divided into two groups randomly by means. In the experiment group, the right peroneal nerve of SD rat was cut off,then an 1mm epineural window was created on the neighboring tibial nerve,the distal end of peroneal nerve was sutured to the windowed tibial nerve by means of end-to-side attachment, application of slow-releasing diaphragm which was implanted around the nerve anastomosis with FK506. In the contrast group,there were not the FK506 around the cut after end-to-side neurorrhaphy. The tibial and peroneal nerve trunks were labeled by being in jected with fast blue ( KB) and fluorescence golden ( FG) respectively. The labeled cells in the dorsal root ganglia (DRG) and spinal cord were observed by fluorescence microscopy. Results There were a lot of FB labeled cells in the experiment group than in the contrast group in the DRG and spinal cord. Conclusion Immunosuppresssant FK506 could promote nerve regenerative speed and quality after end-to-side neurorrhaphy of peripheral nerve.
