Intracranial atherosclerotic stenosis is one of the important causes of ischemic stroke. It is of vital importance to guide clinical treatment using imaging methods to diagnose intracranial artery stenosis and accurately assess the degree of stenosis. This article reviews the advantages and shortcomings,advances and clinical application values of diagnosing intracranial artery stenosis using transcranial Doppler ultrasound,transcranial color-coded duplex sonography,intravascular ultrasound,magnetic resonance angiography,computed tomography angiography,and digital subtract angiography,which will provide references for clinicians to select ideal checking tools.

Based on research of the Accreditation Commission for Acupuncture and Oriental Medicine (ACAOM), the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM) and the related public websites of acupuncture educational institutions, the first hand information was studied, summarized and sorted on the status quo of the educational qualification or the relative authentication of education programs of ACAOM as well as the status of professional qualification and examination of NCCAOM. The education curriculum of the Master degree of Acupuncture, Master degree of Oriental Medicine Science as well as the Doctor degree of Acupuncture and Oriental Medicine were also introduced in this article including student enrollment and graduation in recent years. The developing tendency of the federal unified acupuncture education, management, professional qualification and examination system of U. S. A. were discussed and analyzed as well.

Objective To approach the feasibility of the development and routinely carrying out of gynecological analgesia. Methods A total of 286 pregnant women, 58 were primiparae with full-term fetus and 228 were for mid-term delivery or induced abortion, were enrolled in present study. The combined lumbar-epidural analgesia (CLEA) and the patient-controlled epidural analgesia (PCEA) were given to the primiparae and the ones for mid-term delivery, and the intravenous anesthesia was given to those for induced abortion. Results Among the primiparae and the ones for mid-term delivery, VAS scores were rapidly reduced from 87.7?12.5 and 51.1?14.1 to 8.7?8.8 and 10.6?6.2, respectively, within 3 minutes by CLEA, the effective rates of analgesia were 94% and 100%, respectively. For all of them the Bromage evaluation was in 0 degree. After the induction of labor, no algesia memory existed in the women for induced abortion, the operative time was 15.28?2.57 minutes, the dosage of propoful was 162.9?39.8 mg (about 3mg/kg), and the dosage of fentanyl was 0.05 mg. The incidence of hypotension after intravenous anesthesia was 5.8%. Conclusions Intravenous anesthesia with propoful may remit the panic and fearful sense of pregnant women to induced abortion, and reduce the pain during operation. It is suggested to develop widely and carry out routinely the intravenous anesthesia as an effective and safe technique in gynecological analgesia.

Objective To study the influences of ginsenoside Re on learning and memory abilities of natural apolexis rats and to probe its preliminary mechanism.Method Water maze test for old rats was used to observe the effect of ginsenoside Re on learning and memory,and electrophysiological technique to record the long-term potentiation(LTP)in basic synaptic transmission of the dentate gyrus in anesthetized rats.Results Ginsenoside Re can markedly counteract memory acquisition impairment in natural apolexis rats,and enhance the synaptic transmission in the dentate gyrus and form the LTP consequence.Conclusion Ginsenoside Re can improve the learning and memory obstacle in rats,the mechanism may correlate with its enhancing the basic synaptic transmission and promoting the magnitude of LTP of the dentate gyrus.

Objective To evaluate the clinical application of VAMTS in lung cancer patients.Meth- ods Between May 2004 and June 2005,30 patients with lung cancer applied VAMTS.The minimalthoracto- my from 8 to 10 cm was made at fourth or fifth intercostal space and lobectomy was undergone for convertion- al or dedicated endoscopic instruments.Some mediastinum lymphnode(MLN)resection were performed.Re- suits Operative time from 50 to 210 minutes and average 123 minutes.The intraoperative blood loss is less, and without blood transfusion.The average drawing duct time is 3.9 days.No death caused by operation and postoperative syndromes.Conclusion VAMTS wounds much less,operative scale lumination is better,opera- tive time shorter,blood loss less,and recover more quickly.The hospitalization time is shorter.The VAMTS with MLNR is regarded as an implement of lung cancer remedy,fits to stageⅠ-Ⅱ,diameter

Rat hepatic oval cell model was induced by hyperglycemia and streptozotocin in vivo. Expression of insulin and mRNA expression of pancreatic transcription factors(Nkx6.1, PDX-1) were carried out. It showed that under high glucose, liver tissues were positive for insulin staining, the expression of Nkx6.1 and Pdx-1mRNA was significantly enhanced, and insulin-1mRNA was found to be expressed. The result suggests that under high glucose, hepatic oval cells can differentiate into insulin-producing cells.

BACKGROUND:Colagen materials have good biocompatibility and biodegradability, but also had some problems such as low mechanical strength, poor resistance to degradation exposed in the process of clinical application. Numerous studies have reported that proper crosslinking could improve the disadvantage of colagen materials, regulate porous network structure, sweling and degradation of colagen materials. OBJECTIVE: To optimize carbodimide crosslinking process of colagen sponge and determine the best process conditions. METHODS:Colagen sponge was cross-linked by carbodimide for the preparation of loose and porous colagen sponge. Meanwhile, we optimized the conditions of cross-linking, in which the selected concentration of carbodimide was 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 mmol/L, linking time was 2, 4, 6, 8, 12, 16, 20, 24 hours, and linking temperature was 5, 10, 15, 20, 25, 30, 35℃. We evaluated the best process conditions of colagen sponge through the aperture, porosity, water absorption, and degradation rate. RESULTS AND CONCLUSION:The optimal conditions were carbodimide concentration 50 mmol/L, crosslinking temperature 20℃,crosslinking time 6 hours. At this point, the average pore diameter of colagen sponge was 105 μm, the porosity was 79.45%, water absorption was 287.14%, and the degradation rate was 15.04% (2 days). The crosslinking of colagen sponge significantly improved its water absorption and degradation resistance.

In order to optimize the ~(18)O labeling method, two key aspects, peptide dispersion and trypsin deac tivation were discussed o The addition of Rapigest SF in H_2~('8)O and microwave heating enhanced labeling efficiency of α-casein digested peptides(~(18)O/~(16)O) ratio >99%).Chemical modification with tris(2-carboxyeth yl) phosphine (TCEP) and iodoacetamide (IAA) resulted in trypsin deactivated completely.No significant back-exchange from ~(18)O to ~(16)O was observed after labeling in 6 days.The experiment result with peptide mixture from showed that the improved method could be effectively used to label protein and peptide.
