Purpose: Observe the varities of lymphocyte subgroup of patients suffering from primary hepatic carcinoma ( PHC) during the treatment by hepatic arterial chemoembolization (TACE) and Hyperthemia Peritoneal Perfusion (THPP). Methods: Twenty seven patients were treated with TACE and THPP a week after TACE. We tested for lymphocyte subgroup three times with the flow cytometry (FCM) for pre-TACE, post-TACE and THPP a month later. The control group, twenty seven patients, were also tested for lymphocyte subgroup three times with the TACE. Results: The lymphocyte subgroup among the patients suffering from PHC were disordered. CD4+,CD4+/CD8+.CD19+NK+ were decreased, (P

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.

One hundred and fifty two actinomycetes were isolated from forty two radiation-polluted soil samples,using six different isolation media. Sixty cultures were chosen for 16S rRNA gene sequence and systematic analysis,which based on their morphology and ARDRA. Results of 16S rRNA gene sequences blasting showed that the strains were assigned to 12 recognized genera of actinomycetes,most of them fall within Streptomyces genus and a great deal of strains belonged to rare actinomycetes,which indicated a rich diversity of actinomycetes in the radiation-polluted soil.

ObjectiveTo analyze the clinical outcome of locking plate and hemiarthroplasty in treatment of Neer three- and four-part proximal humeral fractures.Methods A totalof 63 consecutive patients aged over 55 years with Neer three- and four-part proximal humeral fractures were treated surgically from June 2006 to June 2010.In the retrospective study,36 patients were treated by open reduction and locking plate fixation ( locking plate fixation group) and 27 patients treated by hemiarthroplasty (hemiarthroplasty group).Clinical outcomes including operation time,blood loss,visual analog scale ( VAS),Constant-Murley score and complications were evaluated.ResultsThe average 19.7 months follow-up showed complication rate of 28％ in the locking plate group,including one patient with varss malunion,one with axillary nerve injury,one with humeral head necrosis,one with heterotopie calcification and four with impingement syndrome.The complication rate was 24％ in the hemiarthroplasty group,including two patients with tuberosity nonunion,one with tuberosity migration,one with impingement syndrome and one with joint semiluxation.The mean Constant-Murley score of three-part fractures in the locking plate group was ( 76.5 ±5.8) points,better than (69.2 ±7.2) points in the hemiarthroplasty group (P ＜0.05 ).While the two groups showed no significant differences with regards to operation time,blood loss and visual analog scale (VAS).As for the four-part fractures,the mean operation time was shorter and the mean blood loss was less in the hemiarthroplasty group compared with the locking plate group (P ＜0.05),while there were no obvious differences in VAS score and Constant-Murley score between the two groups. Conclusions Both locking plate and hemiarthroplasty are the reliable methods for the three- and four-part proximal humeral fractures.The patients' age,bone quality,fracture type,comminution degree and evaluation of osteonecrosis possibility,are critical for surgery decision.

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.

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 compare the dosimetry difference among three-dimensional conformal radiotherapy (3 DCRT),simplified intensity-modulated radiotherapy (sIMRT) and intensity-modulated radiotherapy (IMRT) in whole pelvic irradiation in postoperative rectal carcinoma,in order to optimize the protocol for clinical practice.Methods From 2006 to 2008,10 patients with stage II and ID rectal cancer after radical resection (Dixon surgery) participated in this study.3DCRT,sIMRT and IMRT were performed for each patient.The dose distribution of target volume and normal tissues,conformal index (CI) and HI were analyzed using the dose-volume histogram (DVH).Results The CI for PTV of IMRT and sIMRT was superior to that of 3DCRT.3DCRT had the best HI in PTV target area dose distribution,while IMRT was similar with sIMRT,however,there were no significant difference among them.As regarded as the protection on organs at risk,for bladder,IMRT was superior to 3DCRT and slightly better than sIMRT;for small intestine,sIMRT showed better performance than 3DCRT while IMRT was better than sIMRT but with no significant difference;for colon,no dosimetry difference was found among three plans;for caput femoris,IMRT and sIMRT were better than 3DCRT.Additionally,sIMRT was similar to 3DCRT in MU of segments,but significantly lower than IMRT.The mean values of total MU for 3DCRT,sIMRT and IMRT were 569.73 ±48.69,542.97 ±69.78,and 770.25 ±73.12,respectively.Conclusions All of 3DCRT,sIMRT and IMRT could provide target area with sufficient and accurate dose,meanwhile they could also protect organs at risk well on rectal cancer after radical resection.Compared with 3DCRT plan and IMRT plan,sIMRT plan might be the optimal plan for clinical practice.
