This study examined the relationship between PDGF-induced proliferation of vascular smooth muscle cells (VSMCs) and Nur77 expression and the effect of atorvastatin on VSMC proliferation and Nur77 in PDGF-treated VSMCs. Rat VSMCs were isolated and cultured. After incubation with atorvastatin or Nur77 siRNA, the cells were stimulated with PDGF and detected for BrdU incorporation to measure the proliferation of the VSMCs. Quantitative PCR and Western blotting were used to determine the Nur77 protein and the CREB phosphorylation level, to observe their relations with PDGF-induced VSMC proliferation. Our results showed that PDGF increased the BrdU incorporation in VSMCs, suggesting that it induced the proliferation of the cells. The VSMC proliferation was associated with increased Nur77 expression and elevated CREB phosphorylation. Atorvastatin inhibited the PDGF-induced VSMC proliferation, suppressed Nur77 expression. After silencing of Nur77 gene, the PDGF-induced VSMC proliferation was decreased. It was concluded that PDGF-induced VSMC proliferation was related to the Nur77 expression and CREB phosphorylation. Atorvastatin reduced the Nur77 expression and, at the same time, inhibited the VSMC proliferation.

OBJECTIVETo explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation.
METHODSFrom January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score.
RESULTSAll incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].
CONCLUSIONTransfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional fixation using hook plate and Kirschner wires is the effective surgical method in treating complete acute acromioclavicular joint dislocation.

Objective To investigate the characteristics and proper use of anticoagulants in hemodialysis (HD). Methods Thirty-one HD patients were enrolled in the study. Unfractionated heparins (UFH), dalteparin sodium or argatroban were used for HD anticoagulation respectively. Blood specimens were taken from the arterial line at the beginning (0 h) and at the end of HD (4 h), and from the arterial (2a) and the venous (2v) line respectively at 2 h of the HD session. Glass bead activated clotting time (gbACT), clot rate (CR) and platelet function (PF) were examined by Sonoclot analyzer. Prothrombin fragment 1+2 (PF1+2) and granule membrane protein-140 (GMP-140) were assayed by ELISA. Meanwhile, blood was taken from 8 healthy volunteers to examine the above parameters as control. Results (1) Compared with the control group, CR, PF1+2, PF, GMP-140 were increased significantly in all the patients (P<0.05). (2) UFH group:Compared with the 0 h point, gbACT of other time points increased significantly (P<0.05), CR, PF, and PF1+2 decreased significantly (P<0.05). Compared with the control group, gbACT increased (P<0.05) and CR decreased (P<0.05) significantly at the end of the sessions. (3) Daheparin sodium group: Compared with the 0 h point, gbACT of 2a point increased significantly (P<0.05), CR and PF1+2 of 2a, 2v and 4 h points decreased significantly (P<0.05), meanwhile, the extents of increased gbACT and decreased CR from the arterial line were greater than those from the venous line. Compared with the control group, gbACT increased significantly at the end of HD session (P<0.05), but CR was not significantly different. (4) Argatroban group: There were no significant differences of gbACT between 0 h and other time points. CR of 2a, 2v points decreased obviously than that of 0 h point, and CR of 2v decreased more significantly. CR of 2a point was not different from the control group, while CR of 4 h point was greater as compared to control group. During the monitoring, PF1 +2 tended to increase. Conclusions With intensive anticoagulant effect, UFH may induce the risk of hemorrhage not only during but also after the dialysis sessions. Dalteparin sodium, a good anticoagulant, is stir related with the risk of hemorrhage during HD. Argatroban is an ideal anticoagulant for patients with the risk of hemorrhage.

Objective To investigate the time distribution characteristics and the epidemic trends of imported malaria cases in Yunnan Province. Methods The malaria case records and epidemiological history data of Yunnan Province were collected, and the local infection cases were excluded. The data were statistical analyzed. Results The imported malaria cases had a sig-nificantly seasonal periodicity(Q=26.574,P<0.05)and epidemic trends(Q=35.487,P<0.05). The imported peak was in May,while February was the lowest month of imported cases,and the difference was significant(Z=-2.619,P<0.05). The simple seasonal prediction model was the best model(R2= 0.677,BIC = 4.867)for forecast while the residual sequence was white noise(Q=14.226,P>0.05). By using the model to predict the cases in January,February and March of 2016,the num-ber(95%CI)were 29(7-50),22(0-44)and 31(8-54),and the actual number of imported malaria cases were 29,24 and 38 cases respectively and all cases were included in the 95%CI. Conclusion The imported malaria cases in Yunnan Province had a significantly seasonal periodicity and epidemic trends,and the established model has good prediction on the recent cases.
