Objective To study the clinical characteristics and imaging features of alien hand syndrome (AHS). Methods We retrospectively analyzed the clinical data of 3 typical cases in our hospital,in comparison with case reports and reviews of domestic and foreign during the past decade. Result All 3 patients showed corpus callosum lesions from CT or MRI detections. The symptoms of the patients included alien hand sign , abnormal involuntary movements, intermanual conflict of upper limbs, and so on. And the patients accompanied with emotional and cognitive changes. Two of them were improved in different degrees after treatment. Conclusion AHS was a complex disease. The diagnosis of this syndrome was based on the advanced neuroimaging. There was still no well established treatment for AHS.

AIM: To establish the quality standard for Compound Songluo Granule (Rhizoma Corydalis, Radix Angelicae Sinensis, Lichen Usneae). METHODS:Rhizoma Corydalis, Radix Angelicae Sinensis were identified by TLC. Usnic acid in Lichen Usneae was determined by TLCS. RESULTS: Rhizoma Corydalis, Radix Angelicae Sinensis could be detected by TLC. Usnic acid showed a good linear relationship at the range of 0. 50～2.50 ?g, r=~0.999 9. The average recovery was 97.5% and RSD was 2.61%, respectively. CONCLUSION:The method is available with a good reproducibility and can be used for the quality control of Compound Songluo Granule.

Thyroid-stimulating hormone receptor(TSHR)is an important autoantigen whose cleavage and shedding can induce autoimmunity.The TSHR is the main functional receptor of the thyroid.The shedding of the ? subunit plays an important role in the forming of TSAb and balancing between TSAb and TBAb.Research on the cleavage and shedding of the TSHR extracellualar domain helps to gain a deep insight into the structure and function of TSHR,illuminate the pathogenesis of autoimmune thyroid disease and find out a new therapy.The structure of TSHR,the mechanism and the significance of its cleavage and shedding are reviewed in this article.

Objective To explore the feasibility and rel ia bility of laparoscopic fundoplication in the treatment of severe gastro-esopha geal reflux disease.Methods Retrospectively forty-two cases of laparoscopic fundop lication were reviewed from June 2001 to March 2004.Results Laparoscopic Nissen fundoplication was performed in 33 cases, and laparoscopic Toupet fundoplication in 9 Symptom score was decreased from 11 56?1 32 to 2 04?1 36 (P

Objective To study on the method of applying laparoseopy for the treatment of choledo cholithiasis after biliary tract operation, and to evaluate its therapeutic efficacy. Methods Thirty-seven cases of common bile duct stones after operation from October 1999 to December 2003, received laparoscopic common bile duct exploration (LCBDE) were retrospectively analyzed. Results Satisfactory results were accepted in 35 cases and the rest two cases converted to laparotomy. Thirty cases had got primary healing by the help of employing endoscopic nasobiliary drainage (ENBD) , 7 cases received T-tube drainage. There was neither residual stones left nor serious after-effect including biliary fistula and hemobilia happened. Mean operative time was ( 168 ?30. 2) min. Mean postoperative stay in hospital was (11.5?1.3) d. Recurrences of calculi and bile duct stricture never happened within 6-48 m follow-up study. Conclusion The laparoscopic procedure is technically feasible and safe alternative, however, the technique in lyses of adhesions, dissection and suture of choledochus are quite difficult, therefore it is recommended to be performed in experienced hands expected to minimize the occurrence of complications, and firmly mastered the indications of conversion to laparotomy as far as possible.

Objective To explore the feasibility and reliability of laparoscopic fundoplication in the treatment of severe gastro-esophageal refulx disease. Methods Five cases of laparoscopic fundoplication were reviewed retrospectively from June 2001 to October 2001. Results Laparoscopic Nissen Fundoplication was performed in 3 cases, Laparoscopic Toupet Fundoplication in 2 cases. Preoperative symptoms were completely relieved. The postoperative esophageal manometry increased from (7 32?1 34)mmHg to (18 20?3 43)mmHg( t =12 23, P

Objective To evaluate the efficacy of laparoscopic and open operation combined with endoscopic nasobiliary drainage(ENBD) in the management of choledocholith. Methods 44 cases treated by laparoscopic common bile duct exploration (LCBDE) and 34 ones by open common bile duct exploration(OCBDE) combined with ENBD and primary suture of common bile duct were retrospectively analyzed from January 1997 to July 2001. Results All cases were operated on successfully. The clearance rate of stones was 100%(78/78). No postoperative complications such as bile leakage, hemobilia, cholangitis, etc occurred. Postoperative hospital stay was (6 2?1 3)days in group LCBDE and (7 4?2 1)days in group OCBDE. 57 cases had been followed up for (1～4 5)years with an average of 2 6 years, and ultrasoundgraphy showed no bile duct stricture and recurrent stones. Conclusions LCBDE or OCBDE combined with ENBD and primary suture of common bile duct is safe and reliable.

Objective To study the causes of conversions to open surgery during laparoscopic cholecystectomy (LC). Methods The study was based on a retrospective review of 156 cases of conversions to laparotomy out of 12672 cases of LC from December 1991 to October 2001 in this hospital. Results Ninety-two (58.97%) cases of conversions were due to complicated clinical condition and preoperative misdiagnosis, 47 (30.13%) cases of conversions due to technological complications, and 17 (10 90%) cases underwent delayed laparotomy. The total conversion rate was 1.23% and the rate of bile duct injuries was 0.2% (26/12672). Conclusions Inadequate preparation, deficiency of experience, complicated clinical situation, and anatomical variation of bile ducts are the leading causes to conversions.

ABSTRACT:Objective To investigate the anti-metastatic effect of allicin on glioma cell line U87 and related mechanisms.Methods In this study,we employed MTT assay to test the anti-proliferative effect of allicin. Transwell assay was used to test the anti-metastatic ability of allicin.Real-time PCR and Western blotting were employed to test the effect of allicin on the expressions of matrix metalloproteinase-2 (MMP-2 ) and matrix metalloproteinase-9 (MMP-9).Western blotting was employed to test the phosphorylated level of p38.Results Allicin could significantly inhibit the proliferation and invasion of U87 cells (concentration>8 μg/mL,P <0.05). Meanwhile allicin (concentration<8μg/mL)could inhibit the invasion of U87 cells.After treatment with allicin for 24 hours,the expressions of MMP-2 and MMP-9 were decreased significantly (P < 0.05 ).Moreover,allicin treatment decreased the phosphorylated level of p38 obviously (P < 0.05 ).Conclusion Allicin inhibits the invasion and migration of glioma cell line U87 by reducing the expressions of MMP-2 and MMP-9 via suppressing the activity of p38 signal pathway,suggesting that allicin is a potential therapeutic agent for glioma.
