Autophagy is a catabolic process involving the degradation of a cell's own proteins and organelles and the subsequent recycle of cellular products. Despite the fact that autophagy helps maintain survival, excessive autophagy can lead to autophagic cell death. Recent researches showed that autophagy played an important role in the development, progression and treatment of colorectal cancer;however, the exact mechanisms of autophagy and its effect on chemotherapy and radiotherapy are still under debate.

Few studies of cetuximab on patients with gastric and esophageal cancer were available now.The disease control rate was 72.7%～92%,OS was 9.5～16.6months,PFS/was 6.2～11 months among first-line setting with cetuximab-contained regimens.And cetuximab shown in second-line regimen setting overcome the resistance of irinotecan and docetaxel.The pCR was 13%～65% when cetuximab was used as induction treatment combined with concurrent chemoradiation.18F-FDG-PET was a potential method to predictthe efficacy of cetuximab-contained regimens,however,status of Kras gene had no predictive value.

Synthetical therapy of laryngeal carcinoma will be a tendency in clinical practice.The induction chemotherapy plays an important role in it.The induction chemotherapy plus radiation compared with surgery plus radiation in patients with advanced laryngeal cancer were applied widely and the significant experiences had also been reported widely. The references of induction chemotherapy of laryngeal cancer were summarized in this paper.

Objective To investigate the clinical effect of the proximal femoral nail anti rotation nail combined with anti osteoporosis drugs in the treatment of intertrochanteric fracture in elderly patients.Methods From October 2014 to October 2015 in our hospital department of orthopedics for PFNA surgical treatment of 80 cases of intertrochanteric fractures in osteoporotic patients, according to the time of admission were divided into simple operation group (control group) and combined group (treatment group),with 40 cases in each group.Both the two groups were treated with PFNA surgery,treatment group were treated with ossification in three alcohol,calcium and calcitonin in the treatment of patients with hip.The fracture healing and hip function were compared between the two groups.Results The treatment group callus appear time,healing time were lower than the control group, the difference was statistically significant (P<0.05);One and three months after operation,the callus scoring of treatment group was higher than control groups (P<0.05);Six months after operation, the bone density of treatment group were higher than control group (P<0.05),the satisfactory rate of treatment group 90.00% was higher than the control group72.50% ( P<0.05 ) .Conclusion PFNA combined with anti-osteoporosis drugs in the treatment of elderly patients with intertrochanteric fracture is conducive to promote fracture healing , improve the condition of osteoporosis in patients with osteoporosis.

Objective:To amplify full-length expressing sequence of human granzyme B(GrB) and perforin(PFP) firstly,then to construct a co-expression vector of pVAX1-PIG and to analyze the expression of human GrB and PFP in Hep-2 cells.Methods:The human PFP and GrB expressing sequences were amplified by RT-PCR.The expression vector pVAX1-PIG was constructed.The recombinant vector was transfected into human Hep-2 cells and their expressions were detected by RT-PCR and indirect immunofluorescent antibody assay.Results:The GrB and PFP cDNA fragment were cloned into the vector of pVAX1 in the right direction.The target proteins were detected in the transfected Hep-2 cells.Conclusion:The vector of pVAX1-PIG was constructed successfully and expressed in Hep-2 cells line.The perforin/granzyme B protein can induce cell apoptosis.These results provide some foundation in gene therapy for tumor by making use of PFP and GrB gene.

Objective To explore the relationship between the expression of P53 protein and the radiosensitivity in patients with advanced maxillary squamous cell carcinoma.Methods An immunohistochomical method wag used to detect the expression of P53 protein in patients with advanced maxillary squamous cell carcinoma.The follow up time was 2 years.The local recurrence of the patients having been treated with radical surgery and affiliated radiotheraphy were analyzed.Results The overexpression of P53 protein in 26 cages was 65.4% (17/26).In the P53 overexpression group,the local recurrence after systiem therapy wag occurred in one case within 6 months,6 cages between 7～12 months.3 cages between 13～18 months and 2 cases between 19～24 months.In the P53 low expression group,there were no recurrence within 6 and 12 months and one case ocurred within 18 months.5 cages between 19～24 months.The difference of recurrence within 18 months after system therapy between the expression of P53 Wag statistically significant(P＜0.05),but it Wag not significant for those within 24 months(P＞0.05).Conclusions The expression of P53 protein Wag correlated with the radiosensitivity in patient with advaneed maxillary squamous cell carciaoma,especially for the resid.rod cells in mitosis phase.The affiliated radiotherapy after radical surgery Wag limited effect.

Objective: To explore the IL\|5 values in the tissue and secretion of nasal polyp. Methods: The concentrations of IL\|5, either in tissue homogenate or in nasal secretion, were measured by ELISA. The values of total protein in tissue homogenate were measured by Bradford colorimetry. In this study, 31 cases with nasal polyp, 8 patients with perennial allergic rhinitis (PAR), 11 cases with chronic sinusitis (CS) and 6 control cases were chosen. Results: ① In tissue homogenate, the IL\|5 concentrations of nasal polyp were higher than that in CS or control group (P＜0.001). ② In nasal secretion, IL\|5 values of both nasal polyp and PAR group were significantly higher than that in CS or control group (P＜0.05). ③ When all cases or only patients with nasal polyp were taken as the subjects, the Pearson correlation coefficient were 0.70, 0.66 respectively. Conclusions: IL\|5 values, both in tissue homogenate and nasal secretion, are significantly higher, which suggested that there were a close relationship between IL\|5 and nasal polyp, and IL\|5 play a key role in the formation of nasal polyp.

Objective:To explore the expression of IL-5 and its role in the formation and development ofnasal polyp. Method: 31 patients with nasal polyp, 11 patients with chronic sinusitis (CS) and 6 control cases werechosen . Their IL-5 concentration in tissue homogenate were measured by ELISA. All patients with chronic si-nusitis,control cases and 15 patients with nasal polyp were chosen to be counted eosinophils in their HE slice.Result :①The values of IL-5(pg/ml) in nasal polyp,CS and control group separately were .. 23.44± 6.68,16.41±3.09,12.86±4.17. IL-5 concentration in nasal polyp group was higher than that in the other two groups( P ＜0. 001). ②The numbers of eosinophils in nasal polyp ,CS and control group were 7.42±2.33,1.30± 0. 59,1.07±0.70 separately,the numbers of eosinophils in nasal polyp group were higher than that in CR or control group(P ＜ 0.05). Conclusion: Nasal polyp is a disease characterized by eosinophilia, and IL-5 which activateseosinophil plays part role in the formation of nasal polyp.

Objective To investigate a method to detect the sentinel lymph nodes(SN) of thyroid papillary carcinoma and its predictive value for cervical metastasis of carcinoma. Methods Intraoperative methylene blue dye mapping was performed in 24 cases of thyroid papillary carcinoma. The coincidence rate of frozen section pathology and routine section pathology of SN was observed,and the predictive value of SN for (metastasis) of the cervical lymph nodes was noted. Results SN was successfully detected in 21(87.5%) of 24 cases. The average number of SN was 3 nodes. There was one false negative case, the false negative rate was 4.8%(1/24), and no false positive cases were found. The predictive value of sentinel lymph nodes to (cervical) lymph node metastasis was 83.3%.Conclusions Methylene blue staining to identify sentinel lymph nodes could accurately predict the status of cervical lymph node metastasis of thyroid papillary carcinoma.
