Objective To study the mutations of Env sequence of SIVmac239 after infection of Chinese rhesus monkeys, and compare the differences and characteristics of Gp120 sequences of enterotropic and neurotropic SIV strains. Methods Six strains of simian immunodeficiency virus were analyzed in this study: four separated from peripheral blood mononuclear cells of SIVmac239-infected monkeys and two neurotropic SIVmac251 strains.Isolated and cultured monoclonal virus was obtained by limiting dilution assay.Gp120 sequences were amplified after the RNA extraction and phylogenetic analysis was processed thereafter.So did the Gp120 amino acid sequence and N-glycosylation sites analysis of the enterotropic and neurotropic strains.Results SIVmac239 had different mutations in four rhesus monkeys.The diversity in amino acid sequences of the enterotropic and neurotropic strains concentrated in the V1 and V4 regions of Gp120.The enterotropic strains had an addition of glycosylation site in V4 but the glycosylation site changes of neurotropic strains were located in the conservative regions of C1, C2 and C3.Conclusions The addition of one glycosylation site in V4 region of GP120 and loss of one glycosylation site in C1 region are associated with enhanced enterotropism and neurotropism.The differences between the enterotropic and neurotropic strains are not dipicted in Gp120 V3 region which is closely related with the tropism of strains.

In order to establish a rapid method for identifying six constituents in Guizhi Fuling capsule, Q-TOF with DART ion source was used to perform the direct analysis of compounds in Guizhi Fuling capsule. The DART sampler delivery rate was 0.2 mm s(-1). The temperature of helium gas of DART was 450 degrees C. The capillary voltage was kept at 1 000 V. The temperature of the drying gas of Agilent 6538 Q-TOF MS was set at 350 degrees C. The flow rate of the drying gas of MS was set at 3.5 L x min(-1). The MS scan range was m/z 50-1 000. Based on accurate mass measurements and the elemental compositions of the product ions and fragmentation patterns of reference conpounds, six components, amygdalin, paeonol, paeoniflorin, cinnamic acids, gallic acid, benzoic acid were identified rapidly. The method can rapidly identify six chemical constituents in three batch of Guizhi Fuling capsule. The DART-Q-TOF-MS method is simple, rapid and specific and it can be used for rapid identification and characterization of compounds in traditional Chinese medicines.

Objective To discuss the value of double-row allograft bone suture anchor in repair of rotator cuff injury. Methods Under assistance of arthroseope, 16 cases of rotator cuff lesions were repaired by using double-row allograft bone suture anchors. There were 10 males and 6 females at average age of 44 years (32-58 years). According to Bigliani classification, there were 6 cases of small ruptures, 8 medial ruptures and 2 large ruptures. After rotator cuff was trimmed and acromial bone was re-shaped under arthroscopy, 2 bone anchors attached to suture lines were implanted in the attachment point of rotate cuff of humerus greater tuberosity side by side. Then, the 4 ends of the 2 suture lines were vertically sutured through tendon of supraspinatus mnscle and tied separately, crossing the 4 ends of 2 knots and penetrated each 2 ends into one bone anchor. Finally, these 2 bone anchors were embedded into 2 predrilled bone holes which were parallel to the former 2 anchors and lower in humerus greater tuberosity. Thus, a web was formed and overlapped on the ruptured rotator cuff. The number of bone anchors was according to the size of rupture. Results All cases were followed up for average 14 months (6-23 months). The mean UCLA score was (21.30±5.6) points preoperatively and (32.4±5.8) points postoperatively. The function of shoulders recovered well, with no pain, recurrence or pulling out of bone anchor. Function was excellent in 10 cases, good in 5 and fair in 1. Conclusions As for repair of rotator cuff injury, double-row bone-anchors under arthroscope can provide a tendon-bone interface better suited for biologic healing of rotator cuff. Bone suture anchor can not leave any foreign object residual and costs less.
