Objective To investigate the clinical characteristics,surgical resection extent and prognosis influencing factors of pri-mary high-risk gastrointestinal stromal tumors(GIST).Methods The clinicopathological and follow-up data of 48 patients with pri-mary resectable high-risk GIST in this hospital from January 2005 to January 2013 were retrospectively analyzed.The influence of three kinds of different surgical resection methods on the prognosis of GIST was analyzed.Results 34 cases were treated by R0 re-section(70.83%),6 cases by R1 resection(11.50%)and 8 cases by R2 resection(16.67%).All cases were given the postoperative adjuvant therapy of imatinib mesylate.The average medication time was(26.5±13.6)months.The occurrence rate of adverse drug reactions was 100%,and the main symptoms were swelling and leukopenia.The 5-year survival rates in 3 kinds of resection modes were 97.06%,66.67% and 25.00% respectively.The univariate and multivariate prognostic analysis showed that the surgical re-section extent and the tumor rupture were the independent prognostic factors in the high-risk GIST patients.Conclusion The intact operative resection and preventing the tumor rupture are the keys to increase the postoperative survival rate of GIST patients.

Objective: To investigate the efficacy of gemcitabine in chemotherapy of cervical carcinoma. Methods:10 untreated cervical carcinoma patients had been divided into two groups,5 cases were treated with neoadjuvant chemotherapy and radiotherapy,others were treated only with radiotherapy. All patients were operated and compared the pathologic changes of cancers. Moreover 3 cases with recurrent tumors had been treated with gemcitabine and other agents . Results: The rate of complete response(CR) was 60% in group of neoadjuvant chemotherapy and 20% in patients with only radiotherapy. Only one case achieved partial response (PR) in patients with recurrence. Conclusion: The neoadjuvant chemotherapy in cervical carcinoma with gemcitabine is helpful for achieving good response .As radiation sensitizer or radio-potentiator,gemcitabine can promote efficacy of neoadjuvant chemotherapy in cervical carcinoma.

Objective: To study the factors relating the prognosis of ovarian granulosa cell tumor and the characteristics of its clinical presentations. Methods: The clinical records and pathological sections of 24 cases with granulosa cell tumor of ovary were reviewed retrospectively. The clinical characteristics, the clinical stage, and the therapeutic programs and the results were summarized respectively. Results:The 5-years survival rate showed that the clinical stage influenced the prognosis of ovarian granulosa cell tumor obviously. Conclusion: The early dection is the major factor which influences the patients' survival rate.

Objective To explore the application effect of Fufukangspray in postpartum women in the treatment of vaginitis . Methods From July 2013 to June 2012 in our hospital ,80 cases of postpartum vaginitis patients as the research object .The control group was treated with Metronidazole Suppositories treatment ,the experimental group were treated with Fufukangspray treatment . Comparison of the two groups in the therapeutic effect and adverse reaction of differences .Results Compared with the control group ,we found that the experimental group total effective rate was significantly higher ,the incidence of adverse reaction was low‐er ,the differences between groups by chi square test analysis that was statistically significant(P<0 .05) .Conclusion Fufukang‐spray has good application effect in the treatment of postpartum vaginitis ,curative effect ,less adverse reactions ,it is worthy of clini‐cal application .

AIM: To investigate the genetic and epigenetic alterations of p14~ ARF gene and mutation status of p53 gene in human primary colorectal carcinomas and to analyze the relationship between the two gene changes and the role of abrogation of the p14~ ARF -p53 pathway in colorectal carcinogenesis. METHODS: The homozygous deletions, mutations, methylation of 5′ CpG islands, mRNA expression of p14~ ARF gene and mutations of p53 gene were assessed by PCR, direct sequencing, methylation-specific PCR, and RT-PCR in the tumorous and matched adjacent normal colorectal tissues from 56 patients with colorectal carcinoma. RESULTS: ① p14~ ARF alterations were detected in 27% (15/56) of colorectal carcinoma tissues studied, of which 1 case showed homozygous deletion, 14 cases showed 5′ CpG island methylation, and no mutation was found in any tumor. ②15 colorectal carcinomas with p14~ ARF alterations indicated lack of (13 cases) or at low level of expression (2 cases) of p14~ ARF mRNA, while expression of the p14~ ARF transcript was detected in the remaining 41 colorectal carcinomas and any matched adjacent normal colorectal tissues. ③ The mutations of p53 gene were detected in 48% (27/56) of colorectal carcinomas investigated. ④ Of these 56 cases, 12 had p14~ ARF alterations alone, 24 had p53 mutations alone, 3 had both p53 mutations and p14~ ARF methylation, and 17 had neither. 70% (39/56) of the samples had either or both abnormalities of the two genes, and p14~ ARF hypermethylation was related to wildtype p53 (P

Objective To investigate the effect of psychological stress on serum iron concentration of SD rats and its mechanism. Method SD rats were randomly divided into four groups: control group (CG), psychological stress 1w group (PG 1w) and 2w group (PG-2w), and psychological stress 2w with 1w free group (PG 2w-1w). The animal model of stress was tested for 1w, 2w, and 2w with 1w free from stress. The iron concentration of serum, liver, spleen and the expression of liver hepcidin were detected by atomic absorption spectrometry and Western blot respectively. Result (1) Compared with control group, serum iron concentration of rats under stress decreased. (2) Free of psychological stress 1w later, serum iron concentration was not significantly changed. (3) Iron concentration of liver and spleen was increased significantly compared with control group, and the expression of liver hepcidin was also increased. Conclusion Psychological stress may cause serum iron of rats to decrease obviously, and it was restored after 1w free from psychological stress. The mechanism is supposed to be increase of iron storage in liver and spleen by hepcidin in rats under psychological stress.

Objective To investigate the effects of Morusin on cell line proliferation, cell cycle and cell apoptosis of colorectal cancer HCT116 cell;To discuss its mechanism. Methods HCT116 cells were treated with different concentrations of Morusin for 72 h. Cell proliferation was detected by CCK-8 assay, and cell growth inhibition rate and IC50 value were calculated. HCT116 cells were treated with 25.4, 50.8 μmol/L Morusin for 24 h, 48 h and 72 h. Cell morphology was observed under the microscope, and cell proliferation was detected by CCK-8 assay. After HCT116 cell line was treated with 25.4μmol/L Morusin for 24 h, cell cycle phase distribution was detected by flow cytometry and the cell apoptosis was detected by TUNEL assay under the fluorescence microscope. Post-intervention protein expressions were detected by Western Blot. Results The inhibitory effects of Morusin on the proliferation of HCT116 cell line was concentration/time dependent and IC50 value at 72 h was 25.4μmol/L;Morusin induced the cell cycle arrest at G0/G1 phase and G2/M phase, but there was no induction of cell apoptosis;Morusin significantly decreased the expression ofβ-catenin and its target c-Myc, and downregulated the expressions of cyclinD1 and cyclinB1, which were involved in cell cycle regulation. Conclusion Morusin can inhibit HCT116 cell cycle and the proliferation of colorectal cancer cells. Its mechanism might be realized by suppressing the activity ofβ-catenin pathway and reducing the protein expressions of cyclinD1 and cyclinB1.

OBJECTIVETo explore the feasibility of the treatment of upper eyelid sulcus using the expanded polytetrafluoroethylene implanted in orbit.

METHODSFrom July 2009 to April 2011, a total of 16 patients with upper eyelid sulcus were treated for recreating youthful periorbital appearance. To correct this kind of clinical characteristic, expanded polytetrafluoroethylene with different size were used as the orbital implant to restore the orbital contents and reinforce the bony support. upper eyelid sulcus was reversed effectively.

RESULTSWith average 2.5 year follow up, upper eyelid sulcus of 16 cases was reversed effectively. No postoperative complication related to globe or affected normal physical function was found.

CONCLUSIONSThe technique of orbital implantation with Expanded Polytetrafluoroethylene is beneficial for the treatment of the upper eyelid sulcus.
