Methods Retrospective analysis was perfomed over 36 GISS patients based on clinical data and pathological data. Results GISS occurred more in the stomach and small intestine, than colon and rectum. Immunohistochemical staining showed CD117, CD34 expression,the positive rates were 91.7% and 86. 1%. Conclusion GISS is a rare malignant tumor, GISS diagnosis depends on the histologic and immunohistochemical test. CD34 and CD117 in the positive diagnosis has its special significance. Surgery is the main treatment.

The purpose of this paper is to present the research on the molecular biological characteristics of proto-oncogene pim-2 and to analyze the related mechanism. Proto-oncogene pim-2 was studied and analyzed by the bioinformatics method and technology. With an online server, the chromosomal localization of pim-2 gene was analyzed, and the exon, open reading frame, CpG island and miRNAs complementary fragments and the like were predicted. With bioinformatics software, the physicochemical property of transcription protein of proto-oncogene pim-2 and various modification sites of protein sequence, such as ubiquitination and glycosylation, were predicted, the antigenic index was calculated, and the spatial structural was modeled. The research findings showed that the proto-oncogene pim-2 comprised six exons, the CDS (coding sequence) transcribed a section of peptide chain including 311 amino acids, a gene promoter has a CpG island, and the 3'UTR region contains an miRNA gene. The molecular weight of the Pim-2 protein was 34,188. 47, the isoelectric point was 5.78, the instability index was 45.87, and the extinction coefficient was 279nm. A plurality of covalent modification sites, two ubiquitination sites, four glycosylation sites, an SUMO sumoylation site, a nitrosation site, two palmitoylation sites and sixteen regions with higher antigenic index were distributed in the protein sequence. This research showed that the related regions and modification sites distributed on the sequence of proto-oncogene pim-2 were closely related to the carcinogenic effect thereof.

Objective To observe the effects of different posture on hemodynamics and plasma atrial natriuretic polypeptide(ANP) during laparoscopic surgery. Methods Forty patients who scheduled for elective laparoscopic surgery under general anesthesia were allocated into two groups according to their posture during laparoscopic surgery,20 cases for each group. In group A, the patients were arranged in a head-down tilt position, in group B, the patients were arranged in a head-up tilt position systolic blood pressure (SBP),diastolic blood pressure (DBP),central venous pressure (CVP) and electro cardio gram (ECC) were monitored continuously. Blood samples were taken from central venous at four time points of prepneumoperitoneum(T1), 10 minutes after that(T2) and 20 mintues(T3) when the patients were arranged at the different operation-needed position with a stable pneumoperitoneum pressure of 14 mm Hg (1 mm Hg = 0.133 kPa),and at 5 minutes (T4) after deflation of pneumoperitoneum when the patients returned to supine position. The plasma ANP was assessed by radioimmunoassay. Results In group A,the CVP at T2 and T3 [(14.45 ±2.72),(14.20 ±2.46) mm Hg] was significantly higher than that at T1 [(6.05 ±1.76) mm Hg] (P<0.01), in group B,the CVP at T2 and T3 [(8.90±1.27),(9.02 ±0.47) mm Hg] was significantly higher than that at T1[(6.30 ±1.34) mm Hg](P< 0.01) ,with a higher level in group A than those in group B at the same time point during pneumoperitoneum(P< 0.01). The ANP level in group A was higher at T2 than that at T1, and there was significantly higher at T3 than that at T1 (P < 0.05). But the ANP level was significantly higher in group A than that in group B at the same time points of T2 and T3 (P < 0.05). Conclusion The posture may have obvious effect on CVP and plasma ANP level during laparoscopic surgery.

OBJECTIVE:To observe the clinical efficacy and safety of pregabalin assisting anti-histamine drugs in the treat-ment of secondary skin pruritus in uremic patients underwent maintenance hemodialysis. METHODS:140 uremic patients with sec-ondary skin pruritus underwent maintenance hemodialysis were randomly divided into control group and treatment group,with 70 cases in each group. Control group was given loratadine orally,10 mg,qd. Treatment group was additionally given pregabalin on the basis of control group,75 mg,po,at night of hemodialysis end,increasing by 75 mg every week if no obvious relief was found,maximal dose of 300 mg. Both group received 3 months of treatment. Clinical efficacy,VAG itching score,modified Duo score,PSQI score before and after treatment and the incidence of ADR were compared between 2 groups. RESULTS:Total effec-tive rate of treatment group (90.00%) was significantly higher than that of control group (71.43%),with statistical significance (P<0.05);VAG itching score,modified Duo score and PSQI score of treatment group after treatment were significantly lower than control group and before treatment,with statistical significance(P<0.05). There was no significant difference in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Pregabalin assisting anti-histamine drugs in the treatment of secondary skin pruritus in uremic patients with maintenance hemodialysis can efficiently relieve the itching symptoms,improve sleep quality,and not increase the risk of ADR.
