Objective To investigate the efficacy and safety of repeated botulinum toxin type A (BTX-A) treatment for Meige's syndrome in senile people. Methods Forty-eight senile patients with Meige's syndrome received BTX-A treatment for twelve times or over. The improvements of spasm were evaluated before and after the first, the sixth and the twelfth treatment according to Cohen's criteria. The onset time, effective duration and side effects were studied and compared among the three times treatments. Results The obvious effective rate of the three times treatment were all 100%. The average onset time of the three times treatments were (3.5± 1.7)days,(3.2±1.8)days and (3.3±1.9)days, and the average effective duration were (25.4±2.1)weeks,(24.6±2.3)weeks and (25.4±1.8)weeks, respectively. The incidences of side effects were 8. 3% (4/48), 6.3(3/48)%and 8.3%(4/48), respectively. All the differences were not statistically significant(P>0.05). Conclusions Repeated BTX-A treatment is an effective and safe method for Meige's syndrome in senile people.

To study the pharmacokinetics of 5 FU after splenic artery(IA) and auricular vein(IV) infusion, portal vein blood was collected for measurement to appraise the clinical value of treatment with this anti tumor drug via different routes on malignant hepatic neoplasms. 5 FU in portal vein blood was measured with high performance liquid chromatography. The results showed that the concentration of 5 FU in IA group was higher than that in the IV group. The peak concentration of 5 FU in the IA group was higher than that in the IV group by 64%. The area under the curve (AUC) of 5 FU in the IA group was larger than that in the IV group by 42%. It suggested that higher concentration of anti tumor drug in the portal vein could be obtained via splenic artery infusion, and it is valuable for the treatment of malignant hepatic neoplasms.

With the modernization of traditional Chinese medicine (TCM), classic extraction methods such as sol-vent extraction, steam distillation, squeezing method, sublimation method have become much more difficult in sat-isfying needs of the development of the society as a result of low extraction rate of effective components, low per-centage impurity clearance. Therefore, in recent years the new extraction techniques with the advantages of green environmental protection , conditional stability , high extraction rate , strong biological activity , have been widely used in TCM extraction. These new extraction techniques have already shown each of its strength. The application progress on new extraction technology of Chinese medicine polysaccharide, both in standalone application and in collaboration application, were discussed in this article, so as to make new technologies be applied more reason-ably and effectively in Chinese medicine polysaccharide components.

ObjectiveTo probe into the ultrasonic(US) predictive value for metastasis of the cervical lateral lymph node(LNM) with the preoperative ultrasonic examination in thyroid papillary microcarcinoma (PTMC),then,to further evaluate the significance of the preoperative ultrasonic score (US) for predicting metastasis of the cervical lateral lymph node.Methods From May 2004 to May 2011,165 patients diagnosed as PTMC (the ultrasonic imaging of lymph node showed no lateral LNM) were retrospectively analyzed and the US and final pathological data from the cases were collected to determine the relevant factors and different scores.ResultsThere were significant differences(P ＜ 0.05 )among US characteristics of microcalcification,no well-defined margin,tumor located at the upper pole,the perimeter of the tumor contacted with the adjacent capsule of thyroid being ＞25 ％ and the presence of the cervical lateral lymph nodes metastasis in PTMC between the metastatic group and the non-metastatic group.The total scores of the ultrasonic ≥2.5 was the delimitation value,its sensitivity was 86.2％ and its specificity was 89.7％.ConclusionsThe ultrasonic score has definite value in the differential diagnosis for the metastasis of the cervical lateral node in the patients of no lateral LNM,when the ultrasonic score is larger than 2.5,the possibility of the cervical lateral lymph node metastasis should be noticed.

Objective To find the clinical and histopathological predictive factors for lateral lymph node ( LN ) metastasis in thyroid papillary microcarcinoma( PTMC ).Methods From January 2007 to December 2010,141 patients with PTMC underwent central and lateral LN dissections were enrolled in the study.The data from the cases were analyzed retrospectively to determine the predictive factors for lateral LN metastasis.Results Among the aforementioned cases,37 cases ( 26.2％ ) were PTMC with the presence of multifocality,24 ( 16.9％ ) Hashimoto thyroiditis,84 ( 59.6％ ) central LN metastasis,56 ( 39.7％ ) lateral LN metastasis.Multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location were significantly related to lateral LN metastasis in univariate analysis( P＜0.05 ).These four factors were also found to be independent predictive factors for lateral LN metastasis in multivariate analysis( P＜0.05 ).9(6.4％ ) of there patients were found to show skip metastasis in which there was lateral LN metastasis but no central LN metastasis.The upper pole location was statistically significantly associated with skip metastasis.Conclusions Patients with multifocality,central LN metastasis,underlying Hashimoto thyroiditis,and upper pole location should be paid more attention to the status of lateral LN.Skip metastasis occurs in a minority of patients with PTMC.Even if there is no central LN metastasis,patients with upper pole lesion should be searched carefully for the lateral cervical LN metastasis.

Background and purpose:hTERT is indistinct in the effect of neo-adjuvant chemotherapy. Our aim was to detect both expression of hTERT mRNA and protein in breast cancer tissue and their changes after neoadjuvant chemotherapy. Methods:From Feb 2004 to Jun 2007, 53 cases with untreated advanced breast cancer were enrolled. All patients received CEF chemotherapy three cycles. The breast cancer tissue was collected before and after chemotherapy. hTERT mRNA and protein expression were detected by RT-PCR and immunohistochemistry techniques. Results:The positive hTERT mRNA and protein expression in breast cancer tissue before chemotherapy were 77.4% and 73.6% respectively, and after neo-adjuvant chemotherapy were 28.3%,22.6% respectively.The effective rate of the neo-adjuvant chemotherapy of the patients with positive of hTERT expression was higher than those with negative hTERT expression. Conclusion:The chemo-agents altered hTERT gene expression, improved negative rate of hTERT expression. Detecting expression of hTERT gene in breast cancer tissue would be an important index for predicting the effects of neo-adjuvant chemotherapy.
