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.

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 .

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.

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 observe the delayed brain myelination of children with phenylketonuria(PKU)combined with epilepsia,and explore effectiveness of the treatment and provide an objective criteria for patient recovering evaluation.Methods There were 42 PKU patients,aged 3 to 72 months were selected.The concentration of phenylalanine tested by high pressure liquid chromatography was greater than 1.2 mmol/L in blood,diagnosed as PKU.According to electroencephalogram and clinical symptom,21 cases were diagnosed as epilepsy,the other 21 cases were used as control group.All patients were taken MRI before treatment.Myelination in 10 sections(cerebellum,pons,mesencephalon,internal capsule posterior limb,corpus callosum,internal capsule anterior limb,occipital lobe,parietal lobe,temporal lobe,frontal lobe)were evaluated.Results Delayed myelinations were located mainly in the cerebral lobes and corpus callosum,average delayed incidence of the 10 region was 44.8% in epilepsy group and 30.9% in control group.The incidence of the corpus callsum was 80.9% in epilepsy group,52.4% in control group,the number of sections of delayed myelination showed statistically significant between 2 groups(P

In the process of evolution, pathogenic Streptococcus pyogenes secretes an immunoglobulin G-degrading enzyme IdeS which can specifically cleave the hinge region of immunoglobulin G in order to escape the immune response against the host. On the one hand, IdeS can be used for IgG fingerprinting as a tool enzyme combined with mass spectrometry technology. On the other hand, IdeS can be used to treat the antibody-responsive diseases produced by autoimmunity as a therapeutic protein. In this study, the backbone of plasmid pCold was used to construct two expression vectors of recombinant protein IdeS, which were heterologously expressed in Escherichia coli Shuffle T7. After purification by affinity chromatography, the recombinant IdeS activity was detected and their activity differences between the two were compared. Among them, the yield of the recombinant IdeS containing the His6-tag at the N-terminus was 4 mg·L^-1, and the cleavage reaction with antibody IgG1 at 1∶200 (m/m) at 37 ℃ for 30 min could complete. However, the yield of the recombinant IdeS containing both the N-terminal His6 tag and the C-terminal silica affinity tag (silica bing peptide, SiBP) is 1.5 mg·L^-1, and the degradation reaction with antibody IgG1 at 1∶20 (m/m) at 37 ℃ for 30 min could reach the end. The C-terminal fusion peptide has a great influence on the yield and activity of IdeS, which is not conducive to subsequent application in drug development. Above all, the recombinant IdeS containing the His6-tag at the N-terminus expressed by this system has high activity and can fully meet the needs of antibody drug development and mapping analysis of IgG.
