Objective To evaluate the prognostic factors in locally advanced non-small-cell lung cancer (LA-NSCLC) for selectively carrying out prophylactic cranial irradiation (PCI).Methods 114 patients with LA-NSCLC between Jun 2006 and Oct 2010 were retrospectively analyzed. Related risk factors and features about brain metastases were analyzed.Results The 2-year incidence rate of brain metastases was 31.58 ％ (36/114),the first brain metastases was 20.18 ％ (23/114),and sole brain metastases was 9.65 ％(11/114),respectively.Variables involved in the equation of binary logistic regression analysis were pathology (OR =5.892) and treatment mode(OR =2.888).The incidence rate of brain metastases in patients of non-squamous carcinoma and single treatment mode was higher than others (P ＜ 0.01) Model fitting is better (P ＞ 0.05).Overall accuracy rate of predicting brain metastases is 67.7 ％.The increased rate of lactate dehydrogenase in the patients with brain metastases or death was 17.54 ％, which was higher than that in the survival patients without brain metastases (P ＜ 0.01).At the same time,the station number and the number of mediastinal lymph node metastases were positively correlated (r =0.716, P ＜ 0.01).The incidence rate of brain metastases or mortality rate was higher in the adenocarcinoma cases than that in the squamous carcinoma cases (P ＜ 0.01,P ＜ 0.05),with more frequent occurrence of mediastinal metastases.The mean diameter of squamous carcinoma and adenocarcinoma were 5.8 cm and 3.9 cm, respectively (P ＜ 0.01).Conclusions The incidence rate of brain metastases was higher in patients with single treatment.Large primary tumors, high lactate dehydrogenase, non-squamous carcinoma, multiple stations, and multiple mediastinal lymph nodes metastases can be regarded as risk factors of brain metastases to perform PCI.

Objective To investigate the effects of T. gondii soluble tachyzoite antigen (STAgs) on the survival time of mouse heart allograft and the possible mechanism. Methods The STAgs were prepared by pulverizing T. gondii tachyzoite with ultrasound on ice. Cervical heterotopic heart transplantations were done by using Balb/c mice as donors, and C57BL/6 mice as recipients.The recipients were classified randomly into three groups: syngeneic group, acute rejection group and STAgs-treated group. The recipients in acute rejection group and STAgs-treated group were injected subcutaneously with 0. 1 ml PBS and 0. 1 ml (5 μg) STAgs at the 4th day before transplantation respectively, and those in syngeneic group were not subjected to any treatment. The grafts were observed daily by cervical palpation, and the total cessation of cardiac contraction was defined as the endpoint. The heart allografts were harvested at the 7th day after transplantation for pathological examination and immunohistochemical staining for CD4+ T, CD8+ T. Results The recipients in syngeneic group were all alive at the 100th day after transplantation. The average survival time in acute rejection group and STAgs-treated group was (6.7± 0.5) days and (70.8± 3.5) days,respectively (P＜0.05). HE staining showed that the rejection on the 7th day after transplantation in syngeneic group, acute rejection group and STAgs-treated group was fallen into 0 degree, Ⅲ-Ⅳ degree and 0- Ⅰ degree, respectively. Immunohistochemical staining revealed that the CD4+ T and CD8+T were markedly down-regulated in STAgs-treated group as compared with those in acute rejection group. Conclusion T. gondii STAgs can significantly prolong the survival time of mouse heart allograft and inhibit the rejection probably by changing the ratio of TH1/TH2, or inhibiting the effect of dendritic cells by inducing the lipoxin A4.

Objective To evaluate the ergotropic effect of bone cement on pedicle screw fixation in treatment of osteopo-rotic thoracolumbar fracture.Methods Fifty-three patients with osteoporotic thoracolumbar fracture, admitted from Jun. 2013 to Dec. 2014, were included for treatment by augmentation of pedicle screw fixation with bone cement. All patients underwent pre-operative examination of bone mineral density with T-score ≤-2.5 and augmentation of pedicle screw fixation with injection of 1.5 ml bone cement in adjacent to fractured vertebra. All patients were treated with anti-osteoporosis therapy pre- and post-operation, ob-served and recorded with basic conditions and complications. At pre-operation, one-week post-operation and last follow-up, pain vi-sual analogue scale (VAS) and neurological function score (ASIA) of all patients were recorded, and the compression rats of anterior and posterior edge of fractured vertebra, and compression rats of spinal canal and Cobb angel of all patients were measured.Results All the 53 patients were successfully undergone operation in about 90-140 min with blood loss of about 150-350 ml. No spinal cord or nerve injury, dural tear and obvious leakage of bone cement and screw loosening occurred during operation. All patients were followed up for 12 to 36 months and the neurological function obviously recovered contrasted with pre-operation. X-ray and CT examination at last follow-up showed good fractures healing, good position and non-loosening of internal fixation device and non-leakage of bone cement. At one week post-operation and last follow-up, VAS, compression rats of anterior edge and posterior edge of fractured vertebra, compression rats of spinal canal and Cobb angel were significantly lower than those at pre-operation (P<0.05), but no significant differences existed on these parameters between 1 week post-operation and last follow-up (P>0.05).Conclusions Augmentation of pedicle screw fixation with bone cement can effectively strengthen the initial stability of pedicle screw in osteo-porosis, restore the height of fractured vertebra and reduce the compression of spinal canal, which will help the correction of spinal kyphosis and neurological function recovery. This method can well maintain long-term stability of internal fixation in osteoporosis and height of fractured vertebra, and significantly reduce the risks of long-term screw loosening and vertebral collapse.

OBJECTIVETo evaluate the inhibitory effect of recombinant adenovirus carrying human endostatin gene (Ad-endo) on the growth of human pancreatic carcinoma xenograft in nude mice.

METHODSThe expression of endostatin in human pancreatic carcinoma Capan-2 cells was examined by RT-PCR after infection with Ad-endo. The supernatants of Capan-2 cells were collected after 48 h of infection with Ad-endo as the conditioned medium for human umbilical vein endothelial cells (HUVECs), whose proliferation in vitro was assayed. Capan-2 cell xenografts were established to determine the antitumoral effects of Ad-endo in vivo. The intratumoral microvessel density (MVD) was evaluated using CD31 staining.

RESULTSThe expression of endostatin gene was detected by PT-PCR in infected Capan-2 cells. The conditioned medium from Ad-endo-infected cells significantly inhibited HUVEC proliferation (P<0.05). Ad-endo significantly suppressed the growth of Capan-2 tumor xenografts in nude mice (P<0.05), and the MVD decreased significantly in the treated tumor (P<0.05) as compared with that in the control group.

CONCLUSIONAdenovirus carrying human endostatin gene produces inhibitory effects on the growth of human pancreatic carcinoma tumors in nude mice.
