Objective To explore therapeutic effects and indications of stereotatic puncture and drainage under multi-parameter orientation in the treatment of hypertensive intracerebral hemorrhage(HICH).Methods A total of 56 patients with HICH underwent stereotatic puncture and drainage from October 2003 to May 2005.The entrance position,the puncture plane,the puncture angle and depth,and the length of side hole of drainage tube were accurately designed before operation,and,if necessary,multiple drainage tubes were introduced via one hole.Results According to the Glasgow Outcome Scale(GOS) scores,12 patients recovered well(21.4%),29 patients were moderate disability(51.8%),and 12 patients were severe disability(21.4%).No longstanding coma was noted.Three patients died(5.4%). Conclusions Stereotatic puncture and drainage under multi-parameter orientation has better therapeutic effects and less damages than open operation.The procedure is suitable for 10~60 ml hematoma,especially in elderly patients and deep-located hematoma.The best operation timing is 3~6 hours after the onset of hemorrhage.

Objective To explore the clinical value of CT-guided selective radiofrequency thermocoagulation of the semilunar ganglion for the treatment of primary trigeminal neuralgia(PTN).Methods A total of 24 patients with PTN were included.Under local anesthesia and CT guidance,the semilunar ganglion was punctured by way of the oval foramen via the anterior approach using the Hartel's technique.Selective radiofrequency thermocoagulation was performed after the targets were confirmed by electrical stimulation. Results The pain was completely relieved in 18 patients,partially relieved in 5 patients,and unchanged in 1 patient,the total effective rate being 95.8%(23/24).Follow-up observations for 3~18 months(mean,12 months) in the 24 patients showed recurrence in 2 patients(8.3%).Conclusions CT-guided selective radiofrequency thermocoagulation is a safe,simple,and effective option for the treatment of PTN,especially suitable for the elderly and high-risk patients.

Objective To analysis the efficacy and safety of endovascular graft exclusion for patients with Stanford type B aortic dissection.Methods The clinical data of 46 patients with Stanford type B aortic dissection who received endovascular graft exclusion were analyzed retrospectively.The stents were inserted from the femoral artery to exclude the tear of dissection,and all operation were peformed under digital subtraction angiography (DSA).The operative technique,outcome and complications were observed.Results The stents were successfully performed in all patients.The length of stay in hospital time after operation was 5-20 (12.9 ± 3.4) d.Endo-leak occurred in 2 patients and relieved after re-expanding.Followed up for 2 d to 5.1 years,average 36 months,1 patient got lacunar infarction and 1 patient died after leaving hospital 2 d.The others were free from the serious complications such as aortic dissection and paraplegia.Conclusion Endovascular graft exclusion is safe and effective for the treatment of Stanford type B aortic dissection in hospital and mid-term,and can significantly improve the survival rate and quality of life.

Objective: To evaluate the genetic toxicity of Thuja essential oil by salmonella reversion test (AMES test) and mammal micronucleus test.Methods: TA97, TA98, TA100 and TA102 were used in AMES test to evaluate the mutagenesis of Thuja essential oil.Mouse bone marrow micronucleus test was conducted to assess the chromosome toxicity of the drug.Results: Both in S9 present and absent situations, the numbers of reverse mutation of Thuja essential oil at different doses for the four strains were all less than 1-fold of that of solvent control, and the difference had no statistical significance (P>0.05), suggesting negative mutation.The micronucleus test indicated that Thuja essential oil had no influence on the rate of mouse bone marrow micronucleus (P>0.05).Conclusion: Thuja essential oil shows no obvious genetic toxicity.

OBJECTIVE:To evaluate the effect of CD44 on drug resistance of breast cancer patients. METHODS:62 breast cancer patients were selected,and the expression of CD44 was detected by immunohistochemical method. Drug resistance was eval-uated by WHO criteria,and the expression of CD44 in breast tissue was observed after observation. RESULTS:There were 48 pa-tients sensitive to CD44 and 14 patients with drug resistance,with statistical significance(P<0.05). After chemotherapy,the ex-pression of CD44 in caner tissue was higher than before chemotherapy,that of patients with drug resistance was higher than pa-tients sensitive to CD44,with statistical significance(P<0.01). CONCLUSIONS:CD44 antigen is closely related to chemothera-py resistance of breast cancer,and high expression of CD44 can be used as an important indicator for breast cancer chemotherapy.

Background and purpose:Glioblastoma is one of the most common intracranial tumors, the morbidity and mortality are both high, and the molecular biological mechanism of the disease is still unclear. In this study, we detected the gene expression of tyrosine kinase receptor (TKR) pathway in primary glioblastoma(GBM) with low-density array, furthermore we analyzed the significance of the gene expression change. Methods:We detected 26 genes of RTK pathway in 10 primary GBM tissues and 9 normal brain tissues (gained from the decompression operation of brain trauma), and analyzed the different expressions of these two kinds of tissues by statistic method.Results:The Ct values of MAP2K1 and MAP2K4 in normal brain tissues were 1.6?1.7 and 2.2?2.1, the Ct values of MAP2K1 and MAP2K4 in primary GBM tissues were 3.9?1.5 and 5.0?2.0, and the Ct different values between normal brain tissues and primary GBM tissues of both genes were -2.3 and -2.8(P
