Objective To discuss the application of digital simulation positioning machine in radiation oncology. Methods We used digital simulation positioning machine to shoot isocenter reset digital simulator images of 0 degrees direction and 90 degrees direction, 10 × 10 cm2 rectangular field and actual time radiation field with any field number. Compared the images taken with the TPS corresponding DRR image through bone marker matching to measure the error of isocenter and actual time radiation field , the linear accelerator Iview-GT system with the same method was shot in rectangular field simulator the same field number EPID image , and the TPS corresponding DRR image. Finally, we compared the measured error of the digital simulator positioning machine with the error of Iview-GT system image. Results The result of measured isocenter error of the digital simulator positioning machine was better than EPID image error (P=0.000). Conclusion The application of digital simulation positioning machine in radiation oncology can be more accurate to measure the error and correct the position deviation, however, it can also make the radiotherapy and the treatment more accurate.

Objective To evaluate the rate of depression in adult rheumatoid arthritis (RA) patients in China.Methods Literature search was conducted to collect studies on the prevalence of depression in adult RA patients in Cochrane library, Medline, EMbase, China National Knowledge Internet (CNKI),China Biology Medicine (CBM), Chinese science & technology journal database (VIP) and Wanfang database.Data were analyzed by R 3.2.0 software after evaluating all data.Results A total of 25 studies, including a total size of 4 830 and 2 712 patients of depression, were eligible for inclusion in the review.The prevalence of depression by analyzing the effect size was 44.7％ [95％CI (37.5％, 52.0％)], which was close to the median of 43.0％ from all studies included and higher than the global rate 38.8％ [95％CI (34％, 43％)].Eight studies, including the sample size of 1 028 cases, 311 cases of mild depressive disorders and 219 cases of moderate or severe depressive disorders, reported the prevalence levels of 30.2％ [30.2％CI (22.1％, 40.0％)] and 16.5％ [95％CI (9.6％,26.9％)], respectively.Subgroup analysis showed that the depression rate of female RA patients was higher than male, the depression rate in the central and western areas were higher than that of the eastern region, the prevalence level estimated by the Geriatric Depression Scale (GDS) was higher than estimated by other tools.Sensitivity analysis showed that the pooled effect size had good stability and reliability.Conclusion The prevalence rate of depression in adult RA patients is 44.7％, suggesting that medical staff should pay much attention to depression in adult RA patients.

Objective To investigate the effect of trastuzumab for injection on apoptosis and the expression of related genes in locally advanced breast cancer and related indexes.Methods 166 patients with locally advanced breast cancer were selected and divided into two groups, 83 cases in the control group treated with neoadjuvant chemotherapy before operation, 83 cases in the experimental group received trastuzumab for injection on the basis of the control group, serum tumor marker levels, tumor cell apoptosis index and proliferation activity, Bcl-2, Bax gene expression levels, the clinical effect and incidence of adverse reactions were compared after the treatment.Results The effective rate in the control group(78.32%)was lower than the experimental group(90.36%), with significant difference (P<0.05).Compared with the control group, serum levels of CA153,CA125,CEA,TSGF were lower in the experimental group after chemotherapy, levels of apoptosis index(AI) in tumor tissue was higher, levels of S-phase fraction (SPF), proliferation index ( PI) were lower after treatment, Bcl-2 gene in tumor tissue expression level was lower, Bax gene expression level was higher after treatment, all with significant difference (P<0.05).There was no significant difference in the incidence of adverse reactions between two groups. Conclusion The trastuzumab for injection treatment can significantly improve the total remission rate of patients with locally advanced breast cancer , reduce the levels of serum tumor markers, can down-regulate the expression of apoptosis related gene Bcl-2, up-regulate the expression of Bax gene, promote the apoptosis of tumor cells.

Objective To investigate the effect of pentoxifyccine (FIX) on the pathway of high glucosd-induced expression of CTGF in mesangial cells. Methods Cultured rat mesangial celld were used to study the influence of different concentration of high glucose on the expression of TGF-β, CTGF, p-Smad2/3, Smad7 and FN in different exposure time. Furthermore the effect of high glucose plus TGF-β neutral antibody and different concentration of FIX on the obove expression was evaluated as well. Results High glucose could increase TGF-β, CTGF mRNA and protein expression in mesangial cells (P<0.05) in time-and dose-dependent manner, and at the same time p-Smad2/3 expression increased and Smad7 expression decreased (P<0.05).The blockage of TGF-β could decrease high glucose-induced CTGF mRNA and protein expression by 86.4% and 91.8%. PTX could suppress high glucose-induced CTGF expression in mesangial cells. When the PTX dosage increased, the suppressive effect became more remarkable, but PTX had no influence on the TGF-β expression. Conclusions High glucose up-regulates CTGF mRNA and protein expression mainly through TGF-β-Smads pathway. PTX can suppress CTGF expression effectively, but has no direct inhibition of TGF-β expression.

Objective To observe the effect of adding on glimepiride in treating type 2 diabetic patients who had suffered the disease for more than 10 years and were poorly controlled with insulin combined with nonsulfonylureas drugs. Methods Seventy-five type 2 diabetic patients poorly controlled with insulin combined with non-sulfonylureas drugs were randomly divided into glimepiride-added group (INS+GM, n = 39 )and continuation of insulin group ( INS, n = 35 ). HbA1c, plasma glucose, daily insulin dose, number of hypoglycemic events, body weight, plasma lipid concentration,and high-sensitive C-reactive protein (hs-CRP)were recorded at weeks 0, 12,and 24. The levels of plasma free fatty acid ( FFA), adiponectin, and tumor necrosis factor-α ( TNF-α ) were measured before and 24 weeks after the therapy. Results At 12 and 24 weeks, fasting blood glucose, 2 h postprandial blood glucose,and HbA1c were improved in INS+GM group more markedly than in INS group, and daily insulin dose and body weight were decreased in INS+GM compared with INS ( P＜0. 05 ). The number of hypoglycemic events and plasma lipid concentration did not differ between two groups ( P＜0.05 ). The levels of plasma FFA,TNF-α,hs-CRP, and HOMA-IR were lower in INS+GM than INS ( P＜0.05 ), the adiponectin was higher in INS + GM than INS ( P ＜ 0.05 ). Conclusion Adding glimepiride to insulin therapy resulted in a sustained better glycemic control with less insulin daily dose, decresed body weight, and no increase in hypoglycemic events as compared with the continuing insulin therapy group. Increased adiponectin, as well as decreased plasma FFA and TNF-α may underlie the improvement of insulin resistance with glimepiride treatment.

Objective To explore a surgical method for the treatment of lumbosacral spinal tuberculosis by combination of one-stage focus debridement with anterolateral incision, bone graft fusion with titanium mesh cage and internal fixation with double pedicle crew system.Methods From Sep.2009 to Dec.2012, a total of 8 patients with lumbosacral spinal tuberculosis which included 5 cases of male, 3 cases of female.The age ranged from 20 to 65 years, with a mean of 51.6 years.All patients presented with persistent back pain, 4 patients with radiating pain of unilateral lower limb, 3 with weakness and numbness and 5 with constitutional symptoms including low-grade fever and weight loss.All patients were not associated with active tuberculosis in oth er parts of the body.The patients were given regular anti-TB treatment for at least 4 weeks.By anterolateral incision, common iliac and iliac arteries and veins were dissociated extraperitoneally.The focus was completely debrided through the inferior part of vessels.Then the bone graft fusion was performed with the titanium mesh cage and the internal fixation with a double pedicle crew system was accomplished.After the surgery, patients were treated with continuous anti-TB drugs and with antibiotics to prevent infection.Patients were allowed to move with the protection of waist early and regular follow-up.Results Operation time was 180-360 min, with an average of 225 min.Operative blood loss was 624 ml and drainage volume was 150 ml on average.All cases were cured after surgery.No severe complications were observed during the surgeries.After follow-up of 8 to 30 months (averaged 12months), no recurrence of the tuberculosis was found.The lumbocrural pain improved in all the patients.Complications such as migration, loosening and breaking of the implants were not observed.The vertebral bodies were fused in all patients with an average time of 8.3 months.No case occurred angiemphraxis or internal bleeding.Conclusion The method debrids the focus of lumbosacral spinal tuberculosis thoroughly and implements titanium mesh cage and double pedicle crew system simultaneously.The pedicle screw system is implemented in anterior lumbosacral vertebrae through the inferior part of iliac arteries and veins, which will not lead to angiemphraxis or vascular injuries.The early term outcome is encouraging.This technique is safe and effective to treat severe lumbosacral spinal tuberculosis.
