To study a method for determination of sulfamethoxazole, sulfadiazine and trimethoprim tablets, a compound tablet of sulfamethoxazole, sulfadiazine and trimethoprim. METHOD: A capillary zone electrophoresis (CZE) method was used to assay three components of this compound preparation. RESULTS: The complete separation of components was achieved with 0.05 molL-1 pH 6.0 running phosphate buffer and a constant voltage of 20 kV (current of 95 μA~105 μA). The retention times of individual components were between three and eight minutes and a good linearity was shown between concentration and peak area in the concentration range over 70 μgml-1~750 μgml-1. When acetanilide was used as internal standard, the relative standard deviation (RSD) of each component determined in a batch was less than 1% (n=9). The recovery of each component was not less than 96.45% with RSD less than 3%. The analytical results obtained from 6 samples of clinical use were inconsistent with those by standard method, however the quantity of each sulfa drug was obtained by CZE method. CONCLUSION: The results showed this method is accurate, simple, and rapid. When this method is used, the quantity of each three components is determined, but by the standard method, only the total quantity of the two sulfa drugs is obtained.

Objective To explore the method to reconstruct finger tip. Methods Transplanted the big toe tip to reconstruct the finger tip and anastomosed the artery and nerve of big toe with the artery and nerve of the finger.The venae digitales plantares of finger,toe and venae digitales volares of finger and toe were anastomosed with microsurgery. Results All the reconstituted finger tips were successful.The shape of the reconstituted finger tips were near to the normal finger tip.The shape of the big toes had only a little change. Conclusion Use the big toe tip can reconstruct a beautiful finger tip look like the normal finger.

According to the definition of professional morality in the employed and profession, the employed,service objects varied professions, three aspects must be grasped: the importance of medical technology must be understood fully, the study of evidence based laboratory medicine must be developed for patients; the responsibility for post must be enhanced to afford clinic correct directions. If these were carried out, the good respect and fondness for the medical technology profession should be trained.

Background:Intrahepatic cholestasis is a commonly seen clinical manifestation, and often accompanied with jaundice.Study on clinical characteristics of patients with different degrees of jaundice is helpful for the acknowledge of intrahepatic cholestasis.Aims:To explore the clinical characteristics of intrahepatic cholestasis with jaundice.Methods:General data, biochemistry parameters, etiology and treatment of 703 patients with intrahepatic cholestasis were retrospectively analyzed.Results:Jaundice occurred in 168 patients (23.9%), including 149 mild jaundice, 15 moderate jaundice and 4 severe jaundice.Levels of ALT, AST, ALP, GGT, DBIL, TBIL, ratio of DBIL/TBIL, TBA were significantly increased in jaundice group than in non-jaundice group (P<0.05).Levels of ALT, AST, DBIL, TBIL, TBA were statistically different between groups with different degrees of jaundice (P<0.05), however, no significant differences in ALP, GGT, ratio of DBIL/TBIL were seen (P>0.05).The main etiology of intrahepatic cholestasis were digestive system tumors, cardiovascular diseases, shock, hematologic diseases and primary biliary cholangitis.Ursodeoxycholic acid and S-ademetionine were the main drugs for treatment of intrahepatic cholestasis.Conclusions:For patients with intrahepatic cholestasis, levels of ALT, AST, ALP, GGT are increased with the development of jaundice, and attention on damage of hepatocytes should be paid.The etiology of intrahepatic cholestasis with jaundice involves diseases of different organs and systems, most of them are malignant tumor, cardiovascular diseases, shock and primary biliary cholangitis.

Objective To investigate the effects of children's mentality on mental symptoms during recovery period of ketamine anesthesia. Methods According to the mentality, forty-five children undergoing smalminor surgery were assigned into active group, stable group and fretful group with 15 cases each. Child was anaesthetized by ketamine alone. RP, BP, HR and SpO_2 were recorded at the end of operation, 5,10 and 30 min after operation. Meanwhile the expression, feeling, behavior, talking and activity were observed. Results RR, BP, HR in active group and fretful group were significantly higher than those in stable group. There was a significant difference in the expression, feeling, behavior, talking and activity among three groups. Conclusion Children's mentality has a significant effect on mental symptoms and hemodynamics during recovery period of ketamine anesthesia.

Objective To investigate the effect of intrathecal injection of lentiviral vector-mediated up-regulation of glial cell line-derived neurotrophicfactor (GDNF) on neuropathic pain of chronic constriction injury (CCI) rats.Methods The CCI model was prepared by ligating the sciatic nerve of Sprague-Dawley (SD) rats.Seven days after CCI modeling,a single intrathecal injection of lentiviral vectors (LV)-GDNF was given.Before CCI and 3,5,7,14,and 21 days after CCI modeling,the mechanical pain threshold was tested in rats,and 21 days after surgery,Western blot was used to detect the expression of GDNF protein.Results On 21 days after CCI modeling,GDNF expression was reduced compared to sham group.After intrathecal injection of LV-GDNF,GDNF expression was up-regulated in the spinal cord,and CCI-induced mechanical hyperalgesia in rats was alleviated.Conclusions Intrathecal injection LV-GDNF can up-regulate the expression of GDNF and alleviate neuropathic pain in CCI rats.
