Objective To study the partial laboratory detection indicators in the patients with abnormal cystatin C (Cys C) . Methods The relevant data in the patients of our hospital from August 2014 to February 2014 were collected and the partial labo‐ratory detection indicators were compared between the patients with normal Cys C and the patients with abnormal Cys C .Results Cys C had statistical difference between the kidney disease group and the control group (P<0 .05);Cys C had statistical difference between the abnormal Cys C group and the control group (P<0 .05) ,RBC ,Hb ,HCT (male ,female) in the abnormal Cys C group were lower than the reference ranges ;while GLU ,TP and Alb in the abnormal Cys C group were within the reference ranges ,but lower than those in the control group ,UA was higher than that in the control group with statistical difference (P<0 .05) .Conclu‐sion Certain degree of malnutrition exists in the patients with abnormal Cys C .

In this study, a 3D model of a transtibial monolimb and residual limb was constructed. The stresses on all nodes of the model under the simulus of the load at the Mid-Stance were computed through 3D finite element analysis (FEA). The stress distribution on the internal and external surfaces of the model was obtained. The results indicate that the stresses on socket are lower than those on prosthetic shank; high stress regions are located on the underneath of prosthetic shank and the border section of socket and prosthetic shank. These data will be useful for CAD\CAM system of monolimb designing.

Monolimb is a new type of lower-limb prostheses made of macromolecule polymer, in which the socket and prosthetic shank are integrative. Compared with traditional prosthesis, monolimb is more economical, good-looking and portable, so it indicates a possible direction in the future. Biomechanical research on trans-tibial monolimb is necessary and helpful just like traditional prosthesis. In this article, a 3D FE model based on real geometry shape of an endoskeletal trans-tibial monolimb is established. Keeping the same geometrical shape, three 3D FE models of transtibial monolimbs with different wall thickness are established. The influence of wall thickness on the stress distribution is analyzed under the load corresponding to the subphase of stance of Heel Off. The results indicate that stress within transtibial monolimb and pressure on the surface of soft tissue could be decreased with wall thickness of transtibial monolimb increased. This study will be helpful for the standard of wall thickness in designing transtibial monolimb.

Objective:To observe the effect of herbal cake-partitioned moxibustion on the expressions of mitogen-activated protein kinase (MEK1/2) and extracellular regulatory protein kinase (ERK1/2) in gastric tissues of rats with spleen deficiency syndrome, and to explore the possible mechanisms of herbal cake-partitioned moxibustion in treating spleen deficiency syndrome. Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group (group A), a model group (group B), a ranitidine group (group C), and a herbal cake-partitioned moxibustion group (group D) by random digit, 15 rats in each group. Rat models of spleen deficiency syndrome were made by intragastric administration of 4℃ 200% concentrated Da Huang (Radix et Rhizoma Rhei). After successful modeling, the rats in group C were treated with 25 mg/(kg·bw) ranitidine by intragastric adminstration and rats in group D were treated with herbal cake-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), for 8 d. Excepted for rats in group A, all the other rats were treated with indomethacin at 5 mg/(kg·bw) at 8:00 a.m. on the second day after finishing all the intervention and sacrificed 7 h later to isolate the stomach. Histopathological changes of the gastric tissues were observed under light microscope after hematoxylin-eosin (HE) staining. The protein expressions of MEK1/2 and ERK1/2 in the gastric tissues were detected by immunohistochemistry. Results:After intervention, the gastric mucosal injury in group B was significantly severer than that in group A, with large breakage and ablating; the damage of gastric mucosa was decreased in group C compared with group B; the gastric mucosal surface remained relatively complete, and the status of breakage and ablating was significantly improved. After intervention, compared with group A, the protein expressions of MEK1/2 and ERK1/2 in gastric tissues of the other groups were significantly higher (P<0.01). Compared with group B, the protein expressions of MEK1/2 and ERK1/2 in group C and D were significantly higher (allP<0.01). Compared with group C, the protein expressions of MEK1/2 and ERK1/2 in group D were significantly higher (P<0.01). Conclusion: Herbal cake-partitioned moxibustion promotes the repair of gastric mucosa in rats with spleen deficiency syndrome, via improving protein expressions of MEK1/2 and ERK1/2 in gastric tissues, as well as activating MEK/ERK signaling pathway.

Objective To study the relationship of MR delayed enhancement with cardiac troponin I in hypertrophic cardiomyopathy(HCM)and to evaluate their values on assessing HCM condition and prognosis.Methods Thirty-five HCM patients who were diagnosed by echocardiography were enrolled.All patients were performed MR scan and cTn Ⅰ test of blood.The relationships of MR delayed enhancement, myocardial hypertrophy and cTn Ⅰ were analyzed.Results(1)DE was found in 25 of total 35 HCM patients(71.4%).19 of 35 HCM patients(54.3%)had abnormal increased eTn Ⅰ value.The medians of cTn Ⅰ in patients with DE and without DE(110,5 ?g/ml,respectively)had statistics significance (P

OBJECTIVETo evaluate the virological response of managing chronic hepatitis C (CHC) with peg-interferon alpha-2b (PEG-IFN alpha-2b) and ribavirin.

METHODSWe retrospectively analyzed the virological response of 40 patients with different genotypes of hepatitis C virus (HCV) infection after anti-HCV management. Patients were given different dosages of PEG-IFN alpha-2b and ribavirin based on their weights. The duration of treatment was 48 weeks for patients infected by HCV genotype 1, and was 24 weeks for the others. HCV RNA was tested before treatment, 12 weeks post management, end of treatment, and 24 weeks after treatment stopped.

RESULTSData from 40 patients were collected. Among them, 24 cases experienced HCV genotype 1 infection, and 16 cases were infected with other genotypes. Between these two groups, the early virological responses were 75.0% (18/24) and 87.5% (14/16), the end-of-treatment virological responses were 80.0% (16/20) and 85.7% (12/14), and the sustained virological responses were 56.2% (9/16) and 78.5% (11/14), respectively.

CONCLUSIONBody weight-based customized PEG-IFN alpha-2b in combination with ribavirin can effectively treat patients with different genotypes of CHC.

OBJECTIVETo evaluate the safety and efficacy of hand-assisted laparoscopic surgery (HALS) in colorectal tumors.

METHODSClinical data of 70 patients with colorectal tumors were retrospectively analyzed. All the patients had received HALS colectomy in the Beijing Cancer Hospital. Lapdisc was used for the hand port at the umbilicus. Two additional trocars were used.

RESULTSThere were 38 males and 32 females. The median age was 61(29-89) years. Diagnoses included sigmoid cancer(n=48), sigmoid adenoma(n=4), descending colon cancer (n=3), ascending colon cancer (n=1), rectal cancer (n=13), total colectomy(n=1). The operative time was (126.0±22.5) minutes. The intraoperative blood loss was (75.0±18.8) ml. The mean number of lymph node dissection was(16.8±4.2). The median postoperative hospital stay was 9.4 days. There were no perioperative deaths. One patient developed anastomotic stricture and two anastomotic leak, all of which were successfully managed with conservative treatment.

CONCLUSIONHALS is a safe and effective technique for colectomy.
