One hundred and six patients with hip fracture admitted in hospital from 2011 to 2014 were randomly divided into two groups: 52 patients received celecoxib and parecoxib ( trial group ) and 54 patients received oxycodone hydrochloride and bucinnazine (control group).On d1 and d7 after the surgery, serum levels of C-reactive protein[(26.2 ±5.4) and (10.4 ±2.8) mg/L], tumor necrosis factor-α[(40.6 ±6.1) and (31.8 ±5.3)ng/L], interleukin-6 [(22.3 ±5.7) and (18.3 ±5.2) ng/L] and prostaglandin E2 [(181.1 ± 19.4) and (153.3 ±25.8) ng/L] in trial group were all significantly lower than those in control group [(46.1 ± 14.0) and (22.1 ±5.2)mg/L, (53.2 ±5.3) and (44.6 ±7.4) ng/L, (43.3 ±11.0) and (29.1 ±8.6)ng/L, (354.3 ±105.9) and (251.0 ±37.3)ng/L, all P<005].The length of hospital stay [(11.0 ±2.2) d], rate of lung infections (6/52) and neurological abnormality (3/52) in trial group were significantly lower than those in control group [(15.5 ±1.8) d, 15/54 and 11/54, all P <0.05].The expression of CD4 +CD45 + T cells [(34.9 ±3.7)% vs.(42.5 ±4.3)%] was reduced and CD4 +Foxp3 +T cells [(19.7 ±3.8)% vs.(6.9 ± 1.5)%] was increased at 24 h after surgery in trial group compared with control group( all P<0.05).The results indicates that calecoxib can reduce the inflammatory reaction by promoting CD4 + to Foxp3 + CD4+T cell differentiation and may improve the prognosis of elderly patients with hip fracture.

0.05). Conclusions Autop-hagy/lysosomal pathway was activated immediately after recurrent seizures as indicated by the elevated expression of Beclin1 in cerebral cortex. 3-MA was involved in the regulation of autophagy/lysosomal pathway by down-regulating the expression of Beclin1.

Objective To evaluate the security and effect of combination of adjuvant hormonal thera- py and brachytherapy for localized prostate cancer.Methods 22 patients with T1-T2c prostate cancer were treated with transperineal ultrasound-guide 125I seeds prostate implantation and adjuvant hormonal therapy for 4～7 months.The hormonal therapy include 2-4 months before brachytherapy and 1～4 months after brachytherapy.Results The median operation time was ninety minutes,the median number of ~(125)I seeds used was 56.The follow up time was 12～48 months,the cases of PSA

Objective To discuss and evaluate the value of insertion of inferior vena cava filter in treating lower extremity deep venous thrombosis(DVT).Methods Inferior vena cava filters were placed in 46 patients with lower extremity DVT prior treatment,20 in which were treated by therapy with anticoagulation and thrombolysis,and therapy with pressure gradient,and the other 26 patients by operation and thrombolysis therapy,and therapy with pressure gradient.Whether patients occurred pulmonary embolism was observed and the form and site of filters were monitored by periodic fluoroscopy.Results Inferior vena cava filters were placed successfully in all patients,38 cases were implanted permanence inferior vena cava filter,8 cases were implanted temporary inferior vena cava filter.Symptoms and signs of DVT disappeared or remitted in 44/46 patients after treatment.None of pulmonary embolism was occurred.Follow up 2-24 months(average 13 months) for 36 cases with permanence inferior vena cava filter,there was no complication of the filter and pulmonary embolism occurred.Conclusions The method of inserting inferior vena cava filter is simple and safe,which can prevent pulmonary embolism effectually to offer sufficient safeguard for the treatment of DVT.

ObjectiveTo investigate the hemodynamic changes after multiple firearm injuries in a swine model. Methods Twelve pigs were divided into 2 groups randomly, with control group ( n =6) subjected to catheterization only. Multiple trauma group ( n =6) was subjected to tangential fracture of parietal bone and comminuted fractures of bilateral femora (ISS≥16) using 5 8 mm bullets. The hemodynamic changes, including MAP, PAP, PAWP, CO, SVRI and portal vein blood flow, were observed at different time intervals up to 72 h after trauma or catheterization. At the same time, gastric pHi was measured as well. Results Compared with control group pigs in multiple trauma group suffered a hyperdynamic circulation developed at 48～72 hours. The cardiac output rose and vascular resistance declined obviously. The pulmonary artery pressure and pulmonary capillary wedge pressure elevated significantly. Mean artery pressure, portal vein blood flow and gastric pHi declined significantly. Conclusion Without severe blood loss and hemorrhagic shock, the decrease of portal vein blood flow and viscera underperfusion still took place after multiple firearm injuries.

Objective To investigate whether RelB-silenced bone marrow-derived dendritic cells (BMDC) pulsed with torpedo acetylcholine receptor (TAChR) immuno-dominant peptide Tα_(146～162) can induce tolerance in T cells primed with TAChR. Methods Recombinant lentivirus that produced RelB siRNA and control lentivirus were prepared and used to infect BMDCs. The infected BMDCs were stimulated with LPS,and the resulting cells were designated as DC-siRelB or DC-control, respectively. The mRNA and protein expression of RelB were examined by quantitative real-time PCR and Western blot. Cell surface markers of DC were evaluated by flow cytometry. IL-12 in the supernatant was detected by ELISA. Mice were randomly divided into 6 groups: A1, A2, A3,K1, K2, and K3. On day 0, group A1, A2, and A3 were primed with TAChR in CFA and group K1, K2 and K3 were primed with KLH+CFA. On day 7, group A2 and K2 were injected with Tα_(146～162) pulsed DC-siRelB, group A3 and K3 were injected with Tα_(146～162) pulsed DC-control, while A1 and K1 group received PBS at the same time. On day 14, lymphocyte proliferative response of the 4 groups were measured. Results Recombinant lentivirus including RelBshRNA genes was successfully constructed. RelB siRNA knocked down RelB expression in BMDCs obviously. Compared with DC-control, DC-siRelB expressed a significantly lower level of CD80, CD86, and MHC class II on their surface, producing lower level of IL-12. Compared with group A1 and A3, lymphocyte proliferative response to TAChR of A2 group was suppressed significantly (P<0.05). No different lymphocyte proliferative responses to KLH and ConA were seen in group A1, A2 and A3 (P>0.05). No different lymphocyte proliferative responses were seen in group K1, K2 and K3 (P>0.05). Conclusion Lentiviral-mediated RelB-silenced BMDCs are maturation resistant and can induce antigen-specific tolerance in TAChR primed C57BL/6 mice,which provides a basis for further study of their therapeutic potential in myasthenia gravis.
