From 1990 to 1992, 41 patients with ulcerating or fistulized esophageal carcinoma (EC) were treated by the conventional irradiaton after a nasogastric tube was inserted into the esophageal lumen. The total doses were 60～65GY/6～6.5WKS. The results were: 1/1 CR in patients with small ulcer, 10/13 CR and 2/13 PR in patients with medium-sized ulcer, 2/7 CR and 3/7 PR in patients with large ulcer, 3/10 CR and 5/10 PR in patients with esophageal mediastinal fistula and 1/10 CR and 4/10 PR in patients with esophagel tracheal or bronchial fistula. The total remission rate was 75.6%(31/41). The 1-and 2-year survival rates were 42.8%, 26.6% for EC with ulcer and 25%, 10% for EC with fistula, respectively.

Intraspinal tumors with kinds of pathological type are common in clinic, whose first option of the treatment is the surgical resection.In recent years, neurosurgeons pay more attention to the postoperative stability of spine biomechanics on the basis of the total resection of the tumors.This paper reviews the approaches in intraspinal tumors resection and the methods of the reconstruction of spinal stability postoperatively which influence the stability of spine biomechanics most.

Triptolide(TP)is a diterpenoid epoxide purified from a Chinese herb Tripterygiumwilfordii Hook. f.. lt has been shown to have multiple pharmacological activities,such as anti-tumor,anti-inflammatory,immune-suppressive effects. TP can reduce airway hyperresponsiveness,decrease the proliferation of airway smooth muscle,and produce potential therapeutic effect in airway remodeling. The effect of TP on allergic asthma may be related to its inhibition of maturation of dendritic cells,rebalance of the function of Th1 and Th2,reduction of the secretion of inflammatory factors,and decrease of the infiltration of eosinophils.

so as to increase inclusion body by 32%when compared with placebo.Conclusion As a disulfide bond isomerase,DsbG may also have chaperone activity during EB infecting to host cell.

The quantity and quality of the papers cited by SCI are key standards that measure the level of basic research,academic status and teaching quality of a university.In this paper,we studied on the papers cited by SCI by statistical analysis and comparative methods in 30 well-known Chinese and foreign medical universities from 2001 to 2005.The research result showed that there is some disparity in the scale and condition of the scientific research and the technical level among Chinese medical universities and foreign medical universities.Meanwhile,it Was suggested that how to improve the quantity and quality of the papers cited by SCI in Chinese medical universities.

AIM: To explore the clinical significance of Krüpple-like factor 15 (KLF15) protein expression in the patients with lung adenocarcinoma for exploring the therapeutic and prognositic biomarkers of lung cancer.ME-THODS: Four cases of lung adenocarcinoma tissues and matched adjacent tissues were collected from our hospital, and the expression of KLF15 protein in these tissues was analyzed by Western blot.At the same time, 72 cases of archived paraffin-embedded samples and clinical data of the patients with lung adenocarcinoma were also collected.The KLF15 protein expression in the archived paraffin-embedded lung adenocarcinoma samples was detected by immunohistochemical staining.The correlations between KLF15 protein expression and clinical characteristics of the patients including prognosis were also analyzed.In addition, the KLF15 protein was up-regulated in A549 cells, and then the effects of KLF15 protein on the viability of the cells were measured by CCK-8 assay.RESULTS: The protein expression of KLF15 in the 4 cases of lung adenocarcinoma tissues was significantly lower than that in matched paracancerous tissues.Fifty-three cases of lung adenocarcinoma specimens showed low expression or no expression of KLF15 protein in total 72 cases (73.6%).The 5-year survival rate of the patients with high expression of KLF15 protein in their specimens was higher than that of the patients with the low expression of KLF15 protein (P<0.01), and the expression of KLF15 protein was significantly correlated with the pathological staging (P<0.01) and T stage (P<0.01) of the patients with lung adenocarcinoma.Furthermore, the low expression of KLF15 protein was an important poor prognostic indicator of the patients.Up-regulation of KLF15 protein in the A549 cells significantly inhibited the growth of the cells.CONCLUSION: KLF15 inhibits the growth of lung adenocarcinoma cells.It could be used as a therapeutic target and a prognostic biomarker for the patients with lung adenocarcinoma.

Objective To explore the differences of curative effect and short-term prognosis to severe traumatic brain injury patients with three different early postoperative nutritional supports.Methods A retrospective study was performed on 60 severe traumatic brain injury patients received in Neurosurgical Intensive Care Unit of Northern Jiangsu People's Hospital from July 2014 to July 2016.A total of 60 cases were randomly divided into the early enteral nutrition support therapy group,the early parenteral nutrition group,and the early compound nutrition group.The clinical indicators such as basic clinical characteristics before treatment,the nutrition data in two weeks,the length of stay in the Neurosurgical Intensive Care Unit,complications and GCS scores between the three groups were observed and analyzed.Results The indicators of early compound nutrition group were fasting blood-glucose (5.74 ± 0.64) mmol/L,prealbumin(203.80 ± 10.45) mg/L,total serum protein(61.99 ± 1.34) g/L,blood hemoglobin (114.53 ± 2.69) g/L,C-reactive protein(0.37 ± 0.06) mg/dl.The length of stay in Neurosurgical Intensive Care Unit was (11.6 ± 0.42) days in the compound nutrition group while those in the early enteral nutrition group was (13.20 ±0.42) days and those in the early parenteral nutrition group was(14.65 ± 0.42) days.The postoperative complications of the compound nutrition group were significantly lower than other two groups.The GCS scores of early compound nutrition group was(11.40 ± 1.60),which was the best in three groups.The differences were statistically significant (P ＜ 0.05).Conclusions Early compound nutrition support has an exact curative effect on postoperative severe traumatic brain injury patients in Neurosurgical Intensive Care Unit.It can obviously improve the nutrition status of patients with less complications,shorter length of stay in Neurosurgical Intensive Care Unit,higher safety and lower degree of coma,worth clinical promotion.

To explore the inhibitory effect of hydroxyapatite (HA) particles with different sizes on malignant melanoma A375 cells in vitro, we synthesized 4 short rod-like HA particles using TIPS. Their mean diameters were 998.0 nm (HA1), 511.0 nm (HA2), 244.0 nm (HA3), and 71.6 nm (HA4), respectively. Malignant melanoma A375 cells were co-cultured with HA particles in vitro. Results showed that HA particles smaller than 511.0 nm in mean diameter could always inhibit proliferation of A375 cells, and nanometer-HA particles (HA4) had the strongest inhibitory effect on A375 cell proliferation and the strongest inducing effect on apoptosis. HA particles were distributed in plasma of A375 cells. The ultrastructure changes of A375 cells were found most significant in nanometer-HA particles (HA4) group. We conclude that particle size is a very important influencing factor on anti-tumor effects of HA and that nanometer-HA particle has the strongest inhibitory effect on tumor cell proliferation.
