Objective To investigate thecorrelation between nonmusle myosin heavy chain 9 gene (MYH9) rs12107,signal transducer and activator of transcription (STAT4) rs3024912, Urokinase plasminogen activator (uPA) rs4065 single nucleotide polymorphism and idiopathic Uighur membranous nephropathy (IMN). Methods Patients admittedby People′s Hospital of Xinjiang Uyghur Autonomous Region from June 2011 to May 2015 were selected in the research,of which 45 with IMN (group A),45 patients with IgA nephropathy (group B) and 45 healthy controls(group C). The polymorphisms of rs12107,rs3024912 and rs4065 were measured with direct sequencing, in order to analyzing the correlation between genotype and allele with IMN. Results Group Ars12107 (MYH9) locus genotype CC, C allele (48.9%, 65.6%) frequency were higher than those in group B (13.3%, 33.3%) and group C (20.0%, 46.7%), and the difference was statistically significance (P < 0.05). C allele carriers of the risk of IMN is 2.18 times that of the T allele (95% CI: 1.19-3.97). Univariate Logistic regression analysis of rs12107 CC genotype showed patients with CC genotype faced with high risk of renal failure (OR = 5.56,95% CI:1.27-24.29, P = 0.023) compared with non-CC genotype patients. rs3024912 genotype and allele frequencies showed no significant difference among the three groups (P > 0.05). rs3024912 GG genotype patients showed higher risk of renal failure compared with non-GG genotype patients (95% CI:1.48-26.83, P = 0.013). Only TT genotype was detected on rs4065 locus. TC and CC genotype were not detected. Conclusions MYH9 gene rs12107 locus CC genotype and C allele are associated with susceptibility to IMN in Xinjiang Uygur, and CC genotypes associated with renal function. rs3024912 (STAT4)GG genotype are not susceptibility gene,but associated with renal function in patients with IMN.

OBJECTIVETo study the preparation of xiong-bing microemulsion (XB ME) and its quality evaluation.

METHODXB ME was prepared by using the methods of titration to prepare the Pseudo-ternary phase diagram. The stability and size distribution of XB ME were tested. The contents of TMP and FA in ME were determined by HPLC method.

RESULTThe character of XB ME was stable. The average diameter was 17.6 nm, and a uniform distribution of particle size were achieved. The solubility of TMP in ME was 2.6 g x L(-1), the methodological average recovery was 97.0% with RSD of 1.5% (n=6); The solubility of FA in ME was 0.3 g x L(-1), the methodological average recovery was 95.9% with RSD of 1.9% (n=6).

CONCLUSIONThe results indicated that the quality of XB ME was stable. The method to determine the contents of TMP and FA was accurate and reliable.

Objective To evaluate the effect of hydrogen on mitochondrial fusion during myocardial ischemia-reperfusion (I/R) in aged rats.Methods One hundred and fifty pathogen-free healthy male Sprague-Dawley rats,aged 18 months old,weighing 400-500 g,were divided into 5 groups (n=30 each) using a random number table:control group (group C),sham operation group (group S),group I/R,normal saline group (group NS) and hydrogen-rich saline group (group H).Group C received no treatment.The anterior descending branch was only exposed but not ligated in group S.Myocardial I/R was induced by occlusion of the anterior descending branch of the left coronary artery for 30 rmin followed by reperfusion in I/R,NS and H groups.Hydrogen-rich saline 1 ml/100 g was injected intraperitoneally at 5 min before reperfusion in group H,while normal saline 1 ml/100 g was injected intraperitoneally at 5 min before reperfusion in group NS.The rats were sacrificed at 12 and 24 h of reperfusion,and hearts were removed for examination of the pathological changes and for determination of apoptosis in cardiomyocytes (by TUNEL) and expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues (by Western blot or real-time polymerase chain reaction).The apoptosis index was calculated.Results Compared with C and S groups,the apoptosis index of cardiomyocytes was significantly increased and the expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues was down-regulated at 12 and 24 h of reperfusion in I/R,NS and H groups (P＜0.05).Compared with NS and I/R groups,the apoptosis index of cardiomyocytes was significantly decreased and the expression of Mfn1 and Mfn2 protein and mRNA in myocardial tissues was up-regulated at 12 and 24 h of reperfusion in group H (P＜0.05).The pathological changes of myocardial tissues were significantly attenuated in group H when compared with group I/R.Conclusion The mechanism by which hydrogen attenuates myocardial I/R injury is related to promoting mitochondrial fusion and inhibiting apoptosis in cardiomyocytes of aged rats.

Objective To investigate effects of Danhong on the serum levels of CD137, high-sensitivity C-reactive protein (hs-CRP) and homocysteine (Hcy) in patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome. Methods A total of 126 patients with non-ST elevation acute myocardial infarction complicating metabolic syndrome were enrolled and randomly divided into a conventional treatment group and a Danhong treatment group using a random-digit table, with 63 patients in each group. All patients underwent angiography or percutaneous coronary intervention. The patients in the Danhong treatment group treated with intravenous Danhong 20 ml on the basis of conventional treatment for 1 week. The serum levels of CD137, hs-CRP and Hcy were measured at hospital admission and 10 days after treatment. The severity of coronary artery disease was assessed by the Gensini-score. Results The levels of CD137, hs-CRP and Hcy in both groups after treatment were significantly lower than before treatment (conventional treatment group: t 12.393, 17.408 and 9.458; Danhong treatment group: t 16.110, 17.573 and 13.481; all P<0.01), and the Danhong treatment group were significantly decreased than the conventional treatment group (t 2.815, 3.224 and 3.157, all P<0.01). The serum levels of CD137 and hs-CRP before treatment were significantly correlated with Gensini scores in 126 patients (r 0.720 and 0.562,all P<0.01). Conclusions The serum levels of CD137 and hs-CRP are significantly correlated with the severity of coronary artery disease, intravenous Danhong may has protective effect for coronary artery disease via decreasing CD137 and hs-CRP.

Objective:To evaluate the effect of goal-directed fluid therapy (GDFT) based on stroke volume variation (SVV) guidance on splanchnic perfusion using gastric mucosal pH (pHi) value in elderly patients undergoing lumbar spine surgery.Methods:One hundred and sixty elderly patients of either sex, aged 65-80 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, undergoing elective lumbar spine surgery under general anesthesia, were selected and divided into 2 groups ( n=80 each) using a random number table method: SVV-guided GDFT group (group G) and conventional fluid therapy group (group C). GDFT was performed with SVV<15% as the target in group G, while conventional fluid infusion was performed under the guidance of mean arterial pressure, central venous pressure and urine volume in group C. Intraoperative amount of crystalloid solution infused, amount of colloid solution infused, total volume of fluid infused, amount of bleeding, urine volume, use of vasoactive drugs and perioperative blood transfusion were recorded in both groups.Cardiac index, SVV, pHi, gastric intramucosal partial pressure of CO 2 (PgCO 2), PaCO 2 and results of arterial blood gas analysis were also recorded before induction of anesthesia (T 1), at 1 h after the start of surgery (T 2) and at the end of surgery (T 3). The postoperative complications, time to first flatus, time to defecation and duration of hospital stay were also recorded in both groups. Results:Compared with group C, the amount of intraoperative crystalloid solution infused, total volume of fluid infused, urine volume and requirement for vasoactive drugs were significantly decreased, the amount of colloid solution infused was increased, cardiac index and pHi value were increased at T 2, 3, and SVV, Pg-aCO 2 and arterial blood lactic acid concentrations were decreased ( P<0.05), and no significant changes were found in the intraoperative amount of bleeding, arterial blood pH value, PaCO 2 and base excess, incidence of postoperative complications, time to first flatus, time to defecation and duration of hospital stay in group G ( P>0.05). Conclusions:GDFT based on SVV guidance is superior to traditional fluid therapy in improving splanchnic perfusion in elderly patients undergoing lumbar spine surgery.
