Methods A contrast test on blood SOD and plasma TXB2 and 6-k-PGF1? was given separately to two groups, one group was 74 cases with stroke and the control group was 36 cases in health. Results Content of b1ood SOD in stroke group reduced remarkably compared with the health group (P

Circulating tumor cells(CTCs)are essential for establishing metastasis and recurrence in non-small cell lung cancer(NSCLC). With the development of detection technique,results from recent studies suggest that CTC level could be a supplement for TNM staging system and a prediction marker of prognosis and therapeutic efficacy,and even could be applied for risk assessment of early NSCLC. Furthermore,as a non-invasiveliquid biopsy,detection of CTC can reflect the molecular biology and genetics characteristics of the primary tumor,and subsequently assist in selecting an optimal individualized treatment.

OBJECTIVETo investigate the role of autophagy in acute lung injury (ALI) caused by multiple trauma in rats via pretreat with 3-methyladenine (3-MA).
METHODSForty-five Sprague-Dawley male rats, with age of 4 months and body weight of 250-300 g,were randomly divided into three groups. In the sham group, the rats received sphenotresia only;in the control group, the rats were made model of femur shaft fracture combined with brain injury, and treated with physiological saline by abdominal cavity at 1 hour before making model; in the 3-MA group, the rats were made model of femur shaft fracture combined with brain injury,and treated with 3-MA of 10 mg/kg by abdominal cavity at 1 hour before making model. Histologic changes and the concentration of related inflammatory factors in the damaged lung tissue were examined at 48 h after opteration, at the same time, the effect of 3-MA on the expression of LC-3 II and Beclin-1 was examined through reverse transcriptase polymerase chain reaction technique (RT-PCR).
RESULTSCompared with sham group, LC-3 II and Beclin-1 level in control group at 48 h after operation were obviously increased (P < 0.01). Compared with control group, LC-3 II and Beclin-1 level in 3-MA group at 48 h after operation were obviously decreased (P < 0.01). Compared with sham group, the level of proinflammatory cytokines (TNF-α and IL-6) in control group obviously enhanced (P < 0.01). Compared with control group, above items in 3-MA group was obviously lower (P < 0.01). Compared with control group,the histopathological damage of lung in 3-MA group obviously reduced (P < 0.01).
CONCLUSIONAutophagy can aggravate the acute lung injury caused by fracture of shaft of femur combined with brain injuries,but 3-MA can reduce tissue damage by inhibiting the autophagy and inflammatory response.

Objective To examine the changes in calcium currents in isolated dorsal root ganglion (DRG) neurons in rats with neuropathic pain.Methods The neuropathic pain model was established by modified spinal nerve ligation (SNL) 2 to 4 weeks before electrophysiologic recording. The rat DRG neurons were enzymatically dissociated. Whole -cell patch clamp technique was used to record Ca2+ current.Results In large DRG neurons the mean peak value of electric current-voltage ( Ⅰ - Ⅴ) curve was decreased significantly from ( - 105?13) pA/ pF in control group ( n = 9) to ( - 66?10) pA/pF in neuropathic pain group ( n = 11) (P 0.05) . Conclusion In neuropathic rat Ca2+ currents in large DRG neurons are decreased and the voltage dependence of the fast component of inactivation is shifted to more depolarized potentials. These changes may contribute to hyperalgesia and allodynia of neuropathic pain.

Objective To study the inhibitory effects of dendritic cells modified by sCD41)gene on T lymphocytes phenotypes and cytokines production and the mechanism of inducing donor-specific immune tolerance in vitro.Methods T lymphocytes prepared with Nylon Fiber Column from Balb/c mice(as reaction cells)and DCs of different groups(as stimulation cells)were subjected to primary mixed lymphocyte culture(MLC).After incubation for 7 days,the responsiveness of the cells was de- tected by MTS method at the indicated time points,and supernatants were assayed for IFN-?,IL-2, IL-4,IL-10 by ELISA kits.On the day 5,the cultured cells were assessed for the expression of CD4, CDS,CD25 and CD69 by using flow cytometry(FCM).After secondary MLC for 5 days,the same indexes were assayed hy using the same methods.Results Dendritic cells modified by sCD40 could in- duce the hyporesponsiveness to alloantigen in primary and secondary MLC.In primary MLC,the ex- pression of CD4~+ and CD8~+ T cells and CD4~+ CD25~+,CD8~+ CD25~+,CD4~+ CD69~+,CD8~+ CD69~+ T cells in IX;modified by sCD40 group were less than those in control group(P

Objective:The benefits of postoperative adjuvant therapy method for low-risk early-stage cervical squamous cell carcinoma were investigated. Methods:A total of 133 patients with low-risk early-stage cervical squamous cell carcinoma were treated at Shandong Cancer Hospital&Institute from February 2008 to March 2012. All patients received adjuvant therapy:42 were treated with pelvic ra-diotherapy (RT), 47 were treated with adjuvant chemotherapy (CT)+intracavitary radiotherapy (ICRT), and 44 were treated with concurrent chemoradiation (CCRT). Disease-free survival (DFS) and complications of the therapy were evaluated. Results:No significant differences in DFS were observed in the patients treated with RT, CT+ICRT, and CCRT (P>0.05), and the three-year DFS rates were 94.0%, 93.4%, and 97.6%, respectively. The frequencies of grade III to IV acute toxicities were significantly higher in patients treated with CCRT (34.1%) than in those treated with RT (9.5%) or CT+ICRT (16.7%) (P<0.05). No statistically significant difference was observed between the RT group and the CT+ICRT group (P>0.05). Grade I to II late toxicity was significantly more frequent in the CCRT (25%) and RT (19.0%) groups compared with the CT+ICRT group (4.3%) (P>0.05), but no statistically significant differences were observed between the CCRT and the RT groups (P>0.05). Conclusion:CT+ICRT or RT has a three-year DFS rate equivalent to CCRT but with fewer therapy com-plications for low-risk early-stage cervical squamous cell carcinoma.

Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P < 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P >0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P <0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.
