AIM: To observe the effect of perioperative detail treatment of pterygium.
METHODS:Sixty cases(100 eyes) of pterygium patients were collected from Sep. 2012 to Jan. 2014. All cases were performed modified pterygium excision with limbal epithelial autograft transplantion under microscope. Corneal wound healing, graft survival, and the recurrence of pterygium were observed.
RESULTS:All cases of conjunctival flap survive, corneal wound closed well. The patients were followed up for 7 to 12mo. Among them, 3 eyes recurred and the recurrence rate was 3%. There were no serious complications.
CONCLUSION:In the operation of pterygium excision with limbal epithelial autograft transplantion, standard and detail treatment can significantly improve the clinical effect.

Objective To investigate the influence of mental intervention on the self-image of breast cancer patients.Methods Fifty patients with breast cancer who were hospitalized in our hospital from January to September,2015 were enrolled as the control group in the study,where routine nursing intervention,health education on disease related knowledge and psychological nursing were carried out.During October 2015 to June 2016,50 patients with breast cancer were enrolled as the observation group,where psychological awareness intervention was carried out apart from the routine nursing intervention.The self-image level of breast cancer patients from the two groups was evaluated by self-image questionnaire for breast cancer patients (BIBCQ).Result After intervention,the scores on self-image in the observation group were significantly higher than those in the control group (P＜0.05).Conclusion Mental intervention can improve the self-image of breast cancer patients and help improve their quality of life.

Objective To assess the therapeutic strategies and prognostic factors that influence clinical outcome of malignant fibrous histiocytoma (MFH) of the abdomen. Methods Between Jul 1980 and Nov 2003, 51 intraabdominal MFH patients undergoing resection were retrospectively analyzed. Results Postoperative recurrence developed in 35 patients, with local recurrence in 15 (29. 4% ) , distant metastasis in 20, including lung metastasis in 8 ( 15. 7% ) , liver metastasis in 4(7. 8% ) , and bone metastasis in 6 ( 11. 7% ). The 1-, 3- and 5-year disease-free survival rate was 70. 6% , 43. 1% and 29. 4% , respectively, and the 1-, 3- and 5-year cumulative survival rate was 74. 5% , 52. 9% and 31. 4% , respectively. Conclusions Intraabdominal MFH is a rare entity with high biological aggressiveness and high metastasis potential. Surgical resection has generally been accepted as the treatment of choice for MFH, at the same time, there appears to be a role for radiation therapy, in combination with surgery for better local control, particularly in high-grade lesions.

Objective:To generate rabbit polyclonal antibody against human Argonaute2 (Ago2) protein and to identify its functional characterization for determination of differential expression and cellular localization of Ago2 protein in various cell lines.Methods:DNAstar software was applied for searching the high antigenicity region of Ago2 gene sequence termed k-Ago2.Prokaryotic expressing plasmid was constructed and transformed to E.coli BL21 (DE3) to induce expression by IPTG.The fusion protein was injected into rabbits subcutaneously to produce polyclonal antibodies after purification by gel regaining.ELISA was operated to detect antibody titer.Western blot was used to identify the specificity and sensitivity of the antibodies and detect the differential expression of Ago2 protein in various cell lines.Meanwhile,immunofluorescence experiments were arranged to show cellular localization of Ago2 protein.Results:The prokaryotic expressing plasmid was constructed correctly.K-Ago2 protein was expressed and purified,and then rabbit polyclonal antibodies against Ago2 were generated after immunization with k-Ago2 protein.The titer detected by ELISA was 1∶19 000.Western blot results demonstrated the high specificity of the antibodies.Finally,we successfully observed the differential expression and cellular localization of Ago2 protein in various cell lines.Conclusion:The polyclonal antibody against Ago2 protein has been achieved successfully.It will be propitious for the intensive study of the RNAi mechanism and even profound clinical application.

Objective To explore the expression of caspase-3 in skeletal muscle of the mice in the state of cancer, and to elucidate the relationship between Caspase-3 and apoptosis,consumption of skeletal muscle protein in cancer cachexia.Methods 48 male BALB/c mice were randomly divided into cancer cachexia group and control group (n=24).The mice in cancer cachexia group were inoculated with mouse colon 26 adenocarcinoma cells.The body weights of the mice in two groups were detected daily.Eight mice in each group were executed to test the weight of left gastrocnemius, fiber crosscut area, the expression levels of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6),Caspase-3 proteins and the apoptotic rate of gastrocnemius cells on day 8,14,and 20,respectively. Results The mice in cancer cachexia group appeared cachectic symptoms on day 14,the non-tumor body weight was decreased more than 20% of that in control group (P<0.05).Compared with control group at the same time, the mouse body weight,non-tumor body weight,the weight of left gastrocnemius and the fiber crosscut area of the mice in cancer cachexia group were obviously decreased with the prolongation of inoculation time (P<0.05 ), whereas the expression levels of TNF-α,IL-6,Caspase-3 proteins and the apoptotic rate of muscle cells were obviously increased after tumor inoculation (P<0.05).The level of Caspase-3 protein was negatively correlated with the weight of gastrocnemius and fiber crosscut area (r=-0.716,P<0.05;r=-0.694,P<0.05),and the level of Caspase-3 was positively correlated with the levels of TNF-αand IL-6 (r=0.742,P<0.05;r=0.675,P<0.05).Conclusion Caspase-3 may be a key factor in the protein comsumption of skeletal muscle in cancer cachexia.
