OBJECTIVE:To establish a method for the bacterial endotoxin test of chlorphenamine maleate injection. METHODS: The interference test and bacterial endotoxin test of 28 batches of chlorphenamine maleate injections from 14 manufacturers were carried out in accordance with the bacterial endotoxin test approved by Chinese Pharmacopeia (2005 edition). RESULTS: Diluted to a concentration of below 0.025 mg?mL-1,the samples showed no interference action on bacterial endotoxin test. The limit value of the bacterial endotoxin was 5 EU?mg-1. The results of the bacterial endotoxin test of the 28 batches of samples were all accorded with the standard of the established quality control. CONCLUSION: The established TAL method is applicable for bacterial endotoxin test of chlorphenamine maleate injection.

Objective To detect the changes in cTnI and CK MB during extracorporeal circulation and the myocardial injury by extracorporeal circulation. Methods The value of cTnI and CK MB was determined in 30 persons during extracorporeal circulation. We divided them into 6 groups according to pre operation, 6, 12, 24, 48 and 72 hours after operation. Modified method (Bodor et al) was used to detect cTnI, and immune suppression method to detect CK MB. Results cTnI and CK MB were, cTnI ( ?s ) (5.20?2 80) ?g/L,CK MB ( ?s ) (10.75?4.70) U/L in 28 persons. They elevated 6 hours after operation. 12 24 hours after operation cTnI and CK MB increased to the maximum, cTnI 28.80 71.30 ?g/L,CK MB 55.60 71.30 U/L. During 48 72 hours, CK MB decreased to normal, 49.70 22.80 U/L. cTnI was 9.40 19.80 ?g/L 72 hours after operation. Conclusion Extracorporeal circulation may cause myocardial diseases. cTnI is a more sensitive biochemical marker for myocardial diseases.

Chinese Journal of Postgraduates of Medicine 2017;40(1):40-43
Objective To explore the feasibility, safety and advantage of thoracoscopes pulmonary bulla resection without thoracic closed drainage tube according to the fast track surgery (FTS) theory. Methods The clinical data of 53 patients with pulmonary bulla were retrospectively analyzed. Among them, 29 patients underwent the thoracoscopes pulmonary bulla resection without thoracic closed drainage tube (FTS group), and 24 patients underwent the thoracoscopes pulmonary bulla resection with thoracic closed drainage tube (tradition group). The oxygenation index at 24 h after operation, visual analogue score (VAS) at 24, 48 and 72 h after operation, postoperative complications, postoperative hospital stay and hospital costs were compared between 2 groups. Results There was no statistical difference in oxygenation index at 24 h after operation between FTS group and tradition group:(312.4 ± 16.4) mmHg (1 mmHg=0.133 kPa) vs. (330.6 ± 13.2) mmHg, P>0.05. The VAS at 24, 48 and 72 h after operation in FTS group was significantly lower than that in tradition group:(2.6 ± 1.1) scores vs. (4.3 ± 1.6) scores, (1.6 ± 0.9) scores vs. (3.8 ± 1.4) scores and (0.8 ± 1.0) scores vs. (2.9 ± 1.4) scores, and there was statistical difference (P<0.05). The incidence of postoperative complications, postoperative hospital stay and hospital costs in FTS group were significantly lower than those in tradition group:13.8%(4/29) vs. 37.5% (9/24), (3.2 ± 0.9) d vs. (6.2 ± 1.2) d and (1.3 ± 0.3) × 104 yuan vs. (1.5 ± 0.4) × 104 yuan, and there were statistical differences (P<0.05). Conclusions FTS used in thoracoscopes pulmonary bulla resection is feasible and safe, and has certain advantages.

Objective To explore the mechanism of apeptosis in rheumatoid arthritis synoviocyte induced by dihydroartemisinin. Methods Synovial tissues were cut from rheumatoid arthritis patients when who was under knee prosthesis. Apoptosis was detected with flow cytometry. Western blot was performed to assess ser473-phosphorylated Akt. EMSA (electrophoretic mobility shift assay) was used to ana-lyze NF-κB activation. Results Dihydroartemisin can induce apoptosis in rheumatoid arthritis synoviocyte in a dose-dependent manor from 2.5μmol/L to 10μmol/L. Rheumatoid Arthritis synoviocyte cultured with dihydroartemisinin in 5μmol/L or 10μmoL/L can significantly in-hibit serine 473 phosphorylation in Akt and activation of NF-κB. Conclusion Dihydroartemisinin can induce apoptosis in rheumatoid arthri-tis synoviocyte through Akt signal pathway.

AIM: To investigate antioxidative and antinitrosative effects of volatile oil from A.longiligulare T.L.Wu on dextran sulfate sodium(DSS)-induced ulcerative colitis mice. METHODS: Balb/c mice were fed with 4% DSS solution for 7 d to induce ulcerative colitis.Using biochemical method,the activity of antioxidative enzyme SOD,MDA and NO were determined in normal,model,SASP and three mouse's groups with low,moderate and high volatile oil from A.longiligulare T.L.Wu respectively.At the same time,the activity of iNOS was also measured by immunohistopathology. RESULTS: The concentration of MDA and NO were reduced and SOD increased significantly in high-and moderate-volatile oil groups compared with those in the model group.The activity of iNOS was reduced significantly in high-and moderate-volatile oil groups compared with those in the model group.The results demonstrated that the expression of iNOS was significantly inhibited in DSSinduced ulcerative colitis mice after being treated with high or moderate-dosage volatile oil. CONCLUSION: Volatile oil from A.longiligulare T.L.Wu has antioxidative and antinitrosative effects which may be one of the mechanism for treating UC.
