Objective To investigate the correlation between renal biopsy pathology(RBP) and Renal intertitial fibrosis (RIF).Methods 112 cases of RIF patients were collected in our hospital who had done RBP examination and were di- vided into four groups based on RIF degree.Results 45 cases in light group,22 cases in moderate group,15 cases in se- vere group and 30 cases in control group.With different RIF degree,renal pathology were different.Conclusion IgAN、 LN、FSGS were much more in moderate and severe RIF group compared with those of other groups,MSPGN were seen in any RIF degree groups.

Background and purpose: Increasing evidence has indicated that polymorphisms in the microRNA (miRNA, miR) binding site of target gene can alter the ability of miRNA and modulate the risk of cancer. We aimed to investigate the association between a miR-520a binding site single nucleotide polymorphism (SNP) rs141178472 in the PIK3CA 3’UTR and the risk of colorectal cancer in a Chinese Han population. Methods:The polymorphism rs141178472 was analyzed in a case-control study, including 386 colorectal cancer patients and 394 age-and sex-matched controls. The relationship between the polymorphism and the risk of colorectal cancer was examined by statistical methods. Results:Individuals carrying the rs141178472 CC genotype or C allele had an increased risk of developing colorectal cancer (CC vs TT, OR=1.716, 95%CI:1.084-2.716, P=0.022;C vs T, OR=1.258, 95%CI:1.021-1.551, P=0.033). Furthermore, the expression of PIK3CA was detected in the peripheral blood mononucleated cell of colorectal cancer patients, suggesting that mRNA levels of PIK3CA might be associated with SNP rs141178472. Conclusion:These ifndings provide evidence that a miR-520a binding site polymorphism rs141178472 in the PIK3CA 3’UTR may play crucial roles in the etiology of colorectal cancer.

To explore CD34(+) antigen expression in new diagnosed acute myeloid leukemia (AML) and analyze the prognosis for CD34(+) AML patients, the expression of antigen CD34 in 238 AML patients was detected by indirect immunofluorescence assay. The results showed that CD34 in 92 out of the 238 patients (38.7%) were positive, there was relationship between the CD34(+) expression and FAB subtypes (M(0), M(1)), and no CD34(+) expression was observed in M(3) subtypes. The complete remission rate of CD34(+) AML patients was 32%, which was lower than that of CD34(-) AML (61%). The lymphoid-associated antigen (CD7) was significantly increased in CD34(+) AML patients, compared with CD34(-) patients (P < 0.05). It is concluded that CD34(+) AML patients show poor prognosis and lower CR rate. The detection of CD34 expression is of some value in predicting prognosis in AML.

OBJECTIVETo understand the environmental risk factors on attempted suicide in patients with major depression, and to study the interaction between factors as single nucleotide polymorphism(SNP) of TPH2 gene rs7305115 associated to attempted suicide in major depression.

METHODSPaired case-control study on 215 suicide attempters with major depression (92 male, 123 female) and molecular biological techniques were used to study the relation between TPH2 gene rs7305115 SNP,interrelated environmental factors and the rate of attempted suicide. Controls were paired with cases according to the same gender, similar age (no more than 3 years) and from the same district.

RESULTSThere were remarkably significant differences in gene types and gene frequency between case and control groups (P < 0.001). Data from multivariate conditional logistic regression model analysis showed that hopelessness, negative life-events and family history of suicide were relationship of attempted suicide in patients with major depression with OR values as 0.33 (95% CI: 0.22-0.99), 7.68 (95% CI: 5.79-13.74), 6.64 (95% CI: 2.48-11.04), 2.98 (95% CI: 1.17-5.04) respectively. There was no first level interaction between any of the two risk factors.

CONCLUSIONResults from the study supported the idea that hopelessness, negative life-events and family history of suicide were risk factors of attempted suicide in major deprbssion while TPH2 gene rs7305115 A/A might be the protective factor.

OBJECTIVETo study the effect of Hongjingtian (Gadol) injection on cardiac hemodynamics and myocardial oxygen consumption for analyzing its underlying mechanism in the treatment of coronary heart disease.

METHODA total of 20 dogs anesthetized with pentobarbital sodium (30 mg x kg(-1), i.v.) were evenly randomized into control group, low-dose Gadol (LDG) group, high-dose Gadol (HDG) group and Herbesser Injection group. The blood flow volume (BFV) of the left coronary artery and cardiac output (CO), left ventricular pressure (LVP), maximum ascending rate (dp/dtmax) of LVP, mean arterial pressure (MAP) of the femoral artery, oxygen contents of the coronary artery and coronary vein (venous sinus), oxygen consumption index (OCI), cardiac index (CI), coronary artery resistance (CAR) and total peripheral resistance (TPR) as well as oxygen utilization rate (OUR) were detected respectively.

RESULTAfter venous injection of Gadol, CAR, MAP, TPR, OCI, myocardial oxygen consumption and heart rate lowered significantly (P < 0.05-0.01), while BFV and blood oxygen content of the venous sinus increased considerably (P < 0.05-0.01) in comparison with pre-injection. No significant differences were found in LVP and myocardial contractivity between control group and LDG, and between control and HDG groups respectively.

CONCLUSIONIt showed dilation of the coronary artery and reduction of the cardiac afterload after injection of Gadol. Besides, CO and stroke volume increased considerably and the cardiac effective work was raised without any significant simultaneous increase of both myocardial contractility and LVP. A decrease in the myocardial oxygen consumption and reduction of OCI indicates an improvement of the oxygen supply of the myocardium, and a favorable regulation of the compliance of the cardiac vessels. As a result, the cardiovascular performance was ameliorated. The abovementioned improvement of these indexes may contribute to the therapeutic effect of Gadol in the treatment of coronary heart disease in clinic.

This paper deals with the application of ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry(UPLC-ESI-Q-TOF-MS/MS) method to rapidly determine and analyze the chemical constituents of methanol extract of Urtica hyperborea. We employed UPLC YMC-Triart C18(2. 1 mm×100 mm,1. 9 μm) column to UPLC analysis with acetonitrile-water(containing 0. 4% formic acid) in gradient as mobile phase. The flow rate was 0. 3 m L·min-1 gradient elution and column temperature was 30℃; the injection volume was 4 μL. ESI ion source was used to ensure the data collected in anegative ion mode. The chemical components of U. hyperborea were identified through retention time,exact relative molecular mass,cleavage fragments of MS/MS and reported data.The results indicated that a total of 31 compounds were identified,including 8 flavonoids,14 phenolic compounds,8 phenylpropanoids(4 coumarins and 4 lignans),and 1 steroidal compound,13 of which were confirmed by comparison. The UPLC-ESI-Q-TOF-MS/MS method could rapid identify the chemical components of U. hyperborea. The above compounds were discovered in U. hyperborea for the first time,which could provide theoretical foundation for further research on the basis of the pharmacodynamics of U. hyperborea.

Objective: To explore the survival status and prognostic factors of patients with pancreatic cancer in Hainan. Methods: Clinical data of patients who were diagnosed as pancreatic cancer and visited the First and Second Affiliated Hospital of Hainan Medical University and Haikou People's Hospital from 2013 to 2017 were collected based on electronic medical records. Basic information was collected by a self-designed questionnaire. Data about admission examinations including blood routine examination, blood biochemistry tests, tumour markers tests, imaging examination and other clinical tests were also collected. The date of follow-up via telephone was 30 June 2018. The survival rate was analyzed by the Kaplan-Meier method and the logrank test. Univariate and multivariate analyses were performed with COX regression model. Results: A total of 198 patients were included in the study. Kaplan-Meier results showed that the overall survival (OS) in 6 months and 1, 2, 3 and 5 years was 47.4%, 26.8%, 16.4%, 13.2%, and 8.7%, respectively. The median OS was 5.8 months. Log-rank test analysis found that there were significant differences in OS among patients with different age, surgery status, distant metastasis or absolute number of neutrophils, percentage of neutrophils, absolute number of lymphocytes, neutrophil-to-lymphocyte ratio (NLR), CA199 and carcino-embryonic antigen (P<0.1). COX multivariate analysis showed that age, surgical presence, presence or absence of distant metastasis and NLR were significantly associated OS (P<0.05). Conclusions: Older age, higher NLR and liver or lung metastasis are independent risk factors, while surgical treatment is an independent protective factor for patients with pancreatic cancer.

To provide the ancient literary evidence support for the clinical application and development of classical prescription based on systematical collection and analysis of the ancient Chinese medical literature containing Jinshui Liujun Jian, including its origin and development. Bibliometric analysis was used and information of Jinshui Liujun Jian in ancient Chinese medical literature was then collected for statistical analysis of formula compositions, main indications, dosage, preparation methods, etc. A total of 151 valid items of data were obtained from 48 ancient Chinese medicine books. Jinshui Liujun Jian was first recorded in Jingyue Quanshu written by ZHANG Jiebin. This prescription consisted of Rehmanniae Radix Praeparata, Angelicae Sinensis Radix, Pinelliae Rhizome, Citri Reticulatae Pericarpium, Poria and Glycyrrhizae Radix et Rhizome Praeparata cum Melle, and it was mainly used to treat the deficiency of lung and kidney, edema and excess production of phlegm, or Yin deficiency in the old, insufficient blood-qi, wind-cold evil, cough and disgusting, asthma and excessive phlegm. Doctors in later dynasties mostly followed the prescription compositions, dosages and indications in Jingyue Quanshu, and extended the clinical application of this prescription.
