Objective To Analyze CD4+ cell count which embodies curative effect in HIV and patients with AIDS, who have treated with TCM for half a year. Methods According to CD4+cell count, the patients were divided into 4 phases. Their CD4+cell count were analyzed before and after the treatment. Results 1.Rank sun test showed that CD4+cell count were significantly improved in people who used TCM treatment. On the whole, CD4+cell count was(317.76±175.61) in 1 cu mm before treatment, which was(350.60±175.92) in 1 cu mm after treatment, P<0.01. 2. Ridit showed that patients whose CD4+cell count more than 500 were in phase I. Their R=0.614, and the 95%confidence interval was 0.5702 to 0.6579. Patients whose CD4+cell count more than 350 and less than 500 were in phase II. Their R=0.575, and the 95%confidence interval was 0.5439 to 0.6062. Patients whose CD4+cell count more than 200 and less than 350 were inphase III. Their R=0.460 and the 95%confidence interval was 0.4347 to 0.4849. Patients whose CD4+cell count less than 200 were in phase IV. Their R=0.428, and the 95%confidence interval was 0.3971 to 0.4589. There was no overlap between phase III, phase IV and phase I, phase II in 95% confidence interval. Conclusion TCM has the advantages in strengthening vital qi, but that is worse than western medicine in effort of expelling pathogen.

Nitric oxide (NO) plays an important pathophysiological role in osteoarthritis and cartilage metabolism. To determine the relationship between NO and the synthesis of type II collagen in cartilage, we measured levels of type II collagen by ELISA and procollagen (II) mRNA by RT-PCR in cultured lapine chondrocytes that were incubated with some kinds of reagents. 0.2mM sodium nitroprusside (SNP, a NO donor) can release high levels of NO, decreasing type II collagen, suppressing the expression of procollagen (II) mRNA (COL2A1).At the same time, chondrocytes showed a large increase in NO synthesis, a decrease in type II collagen and COL2A1 mRNA in response to 100u/ml IL-1. When 1mg/ml N-nitro-L-arginine methyl easter (NAME, an inhibitor of NO synthase) was mixed with IL-1, NO production was inhibited, the amounts of type II collagen recovered partially and COL2A1 mRNA recovered completely.These data indicate NO can inhibit type II collagen synthesis as IL-1 downstream molecule by suppressing procollagen (II) mRNA.

A high performance liquid chromatographic method with fluorimetric detector was developed for the simultaneous determination of three sulfonamides in vegetable samples. Vegetable samples were extracted with methanol for three times, and then the combined extracts were evaporated to dryness under reduced pressure at 45 ℃. The residue was dissolved in 0.1 mol/L HCl and the analytes were derivatized with fluorescamine. The chromatographic separation was performed on an ODS column with a gradient elution program using mobile phases based on mixtures of acetonitrile and 0.5% acetic acid aqueous solution. The derivatized compounds were detected with fluorimetric detector. The limit of detection was 1.02-1.29 μg/L and the limit of quantification was 3.4-4.3 μg/kg(fresh weight, F.W.) for three sulfonamides in vegetable. The average recoveries were higher than 87%, inter and intra RSDs were lower than 10% for all samples spiked with 0.2-1.0 μg/g of sulfonamides. The proposed method has been applied to the analysis of vegetables sold in Hefei markets. The result indicated that 3 SAs were found at different degree in the practical vegetable samples with the total concentrations between 0.0726-0.3709 μg/g(F.W.).

BACKGROUND: Different pretreatments of the tendon allograft for repairing hand tendon defect due to traumatic injuries have received much attention in the study of tissue engineering for hand surgeries.OBJECTIVE:To explore the characteristics of deep-frozen glutaraldehyde-treated tendon allograft for repairing hand tendon defect.DESIGN: A self-controlled study.SETTING:Ward of Orthopedic Department, Huizhou People's Central Hospital.PARTICIPANTS:Fifteen patients (aged 20-35 years) with 17 defected tendons were hospitalized in the Department of Orthopedics of Huizhou People's Central Hospital between January 1997 and August 2001. Among the 17 defected tendons, 8 were extensor tendons and 9 flexor tendons,with the length of defects varying from 2 to 9 cm.METHODS:The allogenic tendon grafts were obtained from young donors died in accidents or non-replantable amputated limbs due to traumatic injuries with informed consent obtained from the donors or their family members. These grafts were stored at -80 ℃ and immersed in 3.5 g/L glutaraldehyde solution before transplantation. Surgical operation was conducted following standard microsurgical procedures. According to the assessment criteria for total rang of motion (ROM) recommended by International Hand Surgery Association, the outcome of the surgically repaired hands was graded as excellent, good, acceptable and poor.MAIN OUTCOME MEASURES:Total ROM of the digits and graft rejection.RESULTS:None of the 15 patients was lost for analysis. The follow-up lasted for 8 months, during which 4 transplanted tendons had excellent, 6good, 4 acceptable and 3 poor functions, with a total effective rate of 82.36% (14/17). Neither cortical hormone nor immunosuppressants were used in these cases and no acute graft rejection or rupture of the tendons occurred.CONCLUSION: The antigenicity of the tendon allografts can be lowered after deep freezing of the grafts at -80 ℃ with preoperative glutaraldehyde treatment, which also increases the strength and tenacity of the tendons and decreases the risk for infection. The treated grafts provide a good alternative for autologous tendon graft but the complication of tendon adhesion still awaits to be tackled.

The paper reports the systematic study on felodipine and its impurities in tablets, to improve its quality standards for the control of the related substances. HPLC-DAD, UPLC-MS, IR and NMR methods were used for the isolation of felodipine and its impurities in tablets, their identification and the zebrafish animal model was used for the analysis of the toxic impurities. In felodipine material and its tablets, three impurities are isolated and identified. They are impurity 1 [dimethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], impurity 2 [ethyl methyl 4-(2, 3-dichlorophenyl)-2, 6-dimethylpyridine-3, 5-dicarboxylate] and impurity 3 [diethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], separately. The result of zebrafish animal model analysis showed that the teratogenic effects of four compounds were: impurity 3 > or = felodipine > impurity 1 > impurity 2, lethal effects were as follows: impurity 2 = impurity 3 > felodipine > or = impurity 1. This study confirmed the toxicity of three impurities in felodipine. According to the results, the paper suggested the amendments to the standard of the medicine and provided the support to the control of impurities in the manufacturing process.
