Objective To investigate the effect of low molecular weight heparin (LMWH) on kidney injury in severe acute pancreatitis (SAP). Methods SD rats were randomly divided into 3 groups: Sham operation (S) group,SAP group, and LMWH treatment (LT) group. In LT group LMWH was administrated 4 hours after SAP model establishment. The levels of serum amylase, creatinine (Cr) and tumor necrosis factor alpha (TNF-?), renal morphological change, and the expression of p65 mRNA and protein in renal specimens were determined 24 hours after model establishment or LMWH treatment. Results The levels of serum amylase,Cr,TNF-? in SAP group were significantly higher than those in S group and LT group (all P0.05). The expression of p65 protein and mRNA of renal tissues in SAP group was significantly higher than that in S group and LT group (all P

Objective To study the mechanism of killing microfilariae in host by detecting the change of amino acids in Brugia malayi microfilariae. Methods The composition and contents of amino acid in microfilariae of periodic Brugia malayi before and after the effect of cytotoxicity were analyzed with automatic amino acid analyzer. Results The result showed that microfilariae contained 17 kinds of amino acids, but lacked Tryptophan. The total amount of amino acids of the microfilariae after cytotoxicity was lower than that before cytotoxicity( P

BACKGROUND: Ligamentum flavum hypertrophy is one important cause of spinal stenosis. Ligamentum flavum thickness of more than 4 mm measured on computed tomography (CT) and magnetic resonance imaging is considered hypertrophy, but causes of hypertrophy and distribution characteristics remain poorly understood. Previous studies showed that the ligamentum flavum thickness at the segments L2/3, L3/4, L4/5 and L5/S1 was positively correlated with age.It remains unclear whether ligamentum flavum thickness is associated with nationality, sex and obesity. OBJECTIVE: To retrospectively analyze the risk factors for ligamentum flavum hypertrophy in lumbar spinal stenosis patients from the Xinjiang Uygur Autonomous Region, China.METHODS: We conducted a retrospective, single-center, case analysis at the Sixth Affiliated Hospital, Xinjiang Medical University, China. We collected lumbar CT imaging data of 104 patients diagnosed with lumbar spinal stenosis in the Sixth Affiliated Hospital, Xinjiang Medical University from May 2012 to May 2016. The primary outcome was the ligamentum flavum thickness of patients with different nationalities, sexes, heights, ages, and weights. The secondary outcomes were the morphology of lumbar vertebrae in patients with different nationalities, sexes, heights, ages, and weights; the correlation of nationality, sex, height, age, and weight with ligamentum flavum thickness; results of multiple linear regression analysis of relevant factors for ligamentum flavum hypertrophy. This trial has been registered at clinical Trials.gov (indentifier: NCT03057353). This protocol has been approved by the Medical Ethics Committee of Xinjiang Medical University and will be performed in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. Signed informed consent regarding trial procedure and treatment will be obtained from each participant.DISCUSSION: This study will determine the variations in the ligamentum flavum thickness of lumbar spinal stenosis patients of different nationalities, sexes, heights, ages, and weights in the Xinjiang Uygur Autonomous Region by measuring the ligamentum flavum thickness using CT, and analyzing risk factors for ligamentum flavum hypertrophy; the findings will provide quantitative reference data for preventing lumbar spinal stenosis induced by ligamentum flavum hypertrophy in the Xinjiang Uygur Autonomous Region.

Objective To compare the ultrasonographic manifestations of ligamenta patella and their entheses of healthy volunteers with those of professional athletes. Methods Sonography was performed using a GE Logiq 700 MR Expert Series ultrasound equipment and a 5-10 MHz multifrequency linear array transducer. Fifty-two healthy volunteers and 20 professional athletes underwent sonography on ligamentum patella of both sides. Results The normal ligamenta patella′s contour was regular and sharply defined, appearing as tightly packed echoic structures with fine parallel internal linear echoes with a synovial sheath to a thickness of 0.02 cm. The attaching bone surface was smooth and continuous. The ligamenta patella of male was longer than that of the female(P

Objective To investigate the role of detection of circulation alpha-fetoprotein(AFP) mRNA and telomerase activity in peripheral blood mononuclear cells(PBMC) of patients with hepatocellular carcinoma(HCC).Methods In patients with HCC,benign liver tumors,chronic liver diseases,and healthy volunteers,expression of circulation AFPmRNA and telomerase activity in PBMC were detected using nest reverse transcriptase-PCR(Nest RT-PCR) or PCR-ELISA respectively.Results(1) All the patients with benign liver tumors(n=10),chronic liver diseases(n=30),and healthy volunteers(n=30) had negative expression of circulation AFPmRNA,and the positive rate of circulation AFPmRNA in patients with HCC(73.3%,22/30)(all P

BACKGROUND:Spinal canal decompression reduction fixation combined with bone graft fusion has been extensively applied in the clinic. Bilateral pedicle screw assisted interbody fusion and unilateral pedicle screw assisted interbody fusion are main methods to treat degenerative lumbar spinal stenosis and lumbar spondylolisthesis. OBJECTIVE:To compare early clinical therapeutic effects of bilateral and unilateral pedicle screw assisted interbody fusion in elderly patients with spinal stenosis and degenerative spondylolisthesis. METHODS:A total of 60 elderly patients with spinal stenosis with degenerative lumbar spondylolisthesis were selected, including 37 males and 23 females, at the age of 60 to 78 years old. They were divided into two groups, and subjected to decompression of spinal canal. In the treatment group (n=30), patients received unilateral pedicle screw assisted interbody fusion. In the control group (n=30), patients received bilateral pedicle screw assisted interbody fusion. After treatment, they were folowed up for 1 year. The recovery of joint function was assessed using Japanese Orthopaedic Association scores in both groups. Simultaneously, complications were recorded. RESULTS AND CONCLUSION:Japanese Orthopaedic Association scores were 25.7±1.9 and 25.8±1.8 in the treatment and control groups, respectively, and no significant difference was found between groups. In the treatment group, three cases affected lower limb numbness and two cases suffered from dural tear, with the incidence of complication of 17%. In the control group, three cases affected lower limb numbness and three cases suffered from dural tear, with the incidence of complication of 20%; no significant difference was detected between the two groups. No adverse reaction related to bone graft was found in the two groups. These results confirm that bilateral or unilateral pedicle screw assisted interbody fusion in treatment of degenerative lumbar spondylolisthesis with spinal stenosis obtained good therapeutic effects.

Objective To investigate the expression of oncogenes and tumor suppressor genes in hepatitis B virus (HBV) related hepatocellular carcinoma (HCC). Methods mRNA was extracted from cancerous and paracancerous tissues of 22 patients with HBV related HCC and synthesized into cDNA. The cDNA labeled with 33p dATP was hybridized for cDNA microarray each consisting of 3170 genes or expressed sequence tags (EST). The differential expression genes were searched in gene data base and verified using RT PCR. Results The differential expression of 1369 genes or EST was identified including 121 genes or EST altered 2 times or more in cancerous tissues compared with paracancerous tissues. Compared with paracancerous tissues, 88 showed overexpression and 33 genes were down regulated. The positive expression of transmembrane 4 superfamily member 1 (TM4SF1) in cancerous tissues was 86.4 % and could not be detected in paracancerous tissues (P
