ABSTRACT
Illumina Xten was employed for shallow sequencing of Panax ginseng(ginseng) samples, MISA for screening of SSR loci, and Primer 3 for primer design. Polymorphic primers were screened from 180 primers. From the successfully amplified polymorphic primers, 15 primers which featured clear peak shape, good polymorphism, and ease of statistics were selected and used to evaluate the genetic diversity and germplasm resources of 36 ginseng accessions with different fruit colors from Jilin province. The results showed that red-fruit ginseng population had high genetic diversity with the average number of alleles(N_a) of 1.031 and haploid genetic diversity(h) of 0.172. The neighbor-joining cluster analysis demonstrated that the germplasms of red-fruit and yellow-fruit ginseng populations were obviously intermixed, and pick-fruit ginseng germplasms clustered into a single clade. The results of STRUCTURE analysis showed high proportion of single genotype in pick-fruit ginseng germplasm and abundant genotypes in red-fruit and yellow-fruit ginseng germplasms with obvious germplasm mixing. AMOVA revealed that genetic variation occurred mainly within populations(62.00%, P<0.001), and rarely among populations(39%, P<0.001), but homogenization was obvious among different populations. In summary, pink-fruit ginseng population may contain rare genotypes, which is the basis for breeding of high-quality high-yield, and multi-resistance varieties, genetic improvement of varieties, and sustainable development and utilization of ginseng germplasm resources.

OBJECTIVE@#To evaluate the classification criteria of early rheumatoid arthritis (ERA) and compare the sensitivity and specificity with the criteria of 1987 American College of Rheumatology (ACR) criteria and 2010 ACR/European League Against Rheumatism (EULAR).@*METHODS@#Patients from 4 hospitals, aged more than 16 years, with arthritis, whose disease duration was ≤1 year, and with ≥1 joint pain and swelling were enrolled in the study. The indicators including clinical manifestations, laboratory tests and imaging examinations were observed. The ERA patients were dignosed by two experienced rheumatologists based on the clinical features, drug therapy information and radiography features.@*RESULTS@#(1) A total of 325 patients with arthritis were enrolled, including 98 males (30.15%) and 227 females (69.85%), The average age was (47.53±14.44) years, and the median disease duration was 5 (2, 8) months. Finally, 236 patients were dignosed with ERA, and 89 patients were dignosed with other diseases (Non-ERA, including osteoarthritis, reactive arthritis, undifferentiated arthritis, spondyloarthritis, etc). (2) The sensitivity of ERA criteria was 87.29%, and the specificity was 84.37%. The sensitivity was higher than that of 1987 ACR criteria (χ2=43.641, P < 0.001), and had no significant difference compared with 2010 ACR/EULAR criteria (χ2=0.446, P=0.593). But the specificity of ERA criteria was lower than that of 1987 ACR criteria (χ2=4.891, P=0.027), which was not statistically significant compared with 2010 ACR/EULAR criteria (χ2=0.044, P=1.000). (3) In the patients with arthritis whose disease duration was ≤3 months and ≤6 months, the sensitivity of ERA criteria was 81.71% and 86.79%, respectively, both were higher than the 1987 ACR criteria (χ2=7.131, P=0.008; χ2=22.015, P < 0.001) and had no statistically difference compared with the 2010 ACR/EULAR criteria (χ2=0.220, P=0.755; χ2=0.473, P=0.491). The differences of the three criteria in specificity were not statistically significant. (4) The three different classification criteria were consistent with the clinical diagnosis, among which the ERA criteria and 2010 ACR/EULAR criteria were slightly higher (Kappa>0.6). The results of the consistency comparison between the three criteria showed that the ERA criteria and 2010 ACR/EULAR criteria had a better consistency (Kappa=0.836).@*CONCLUSION@#The sensitivity of ERA classification criteria in the diagnosis of ERA was higher than that of 1987 ACR criteria, and was equivalent to that of 2010 ACR/EULAR criteria. There is no significant difference in specificity between these three criteria. The ERA criteria can also identify patients with RA at a very early stage in arthritis with disease duration ≤3 months.

Objective To compare the feasibility and safety of laparoscopic partial renal segmental artery occlusion and renal artery trunk interruption for partial nephrectomy. Methods We reviewed medical records of 65 patients with stage T1 renal tumor from October 2013 to February 2017. Among them, 29 cases underwent partial nephrectomy with high selective segmental renal artery occlusion, and 36 cases underwent partial nephrectomy with renal artery trunk occlusion. Then compare the preoperative and postoperative creatinine changes, intraoperative blood loss, warm ischemia time, operation time, hospitalization time and positive margins of the two methods. Results In all the patients, the procedures were done without conversion to open surgeries. The operation time of the renal artery branch block group is shorter than that of the main renal artery block, but the preoperative and postoperative creatinine changes are smaller than those of the main renal artery occlusion group. There was no significant difference between the two groups in intraoperative blood loss, warm ischemia time and positive margins (P > 0.05); There was no significant difference between the two groups in age, body mass index (BMI) and R.E.N.A.L score of renal tumor (P > 0.05). Conclusion For the stage T1 renal tumor, the selective renal artery branch interruption technique has a longer operation time, but the renal tissue has a small ischemic zone and has little effect on the kidney.
ABSTRACT
Thrombolysis is the main therapeutic method of acute pulmonary embolism [APE]. In order to investigate the efficacy of reteplase on APE and the changes of cytokines in the progression of APE, 72 patients with APE were randomized into reteplase group and urokinase group which received reteplase thrombolysis and urokinase thrombolysis, respectively. The clinical symptoms, blood pressure, heart rate [HR], blood gas index and cytokines of patients were observed before and after therapy for assessing the thrombolysis effect of each group; blood level of high sensitive Creactive protein [hs-CRP], TNF-alpha, IL-1beta, IL-6 and IL-10 was detected at 0h, 2h, 6h, 12h and 24h after thrombolysis. After treatment, the clinical symptoms of both groups were alleviated obviously; PaO2, PaCO2, blood pressure and HR in both groups were significantly improved than those before treatment [p<0.001], and reteplase group showed a more obvious improvement than urokinase group [p<0.001]. Since 6h after therapy, the content of hs-CRP, IL-1beta and IL-6 in patients of reteplase group declined significantly [p<0.05 or 0.01]. In conclusion, therapeutic effect of reteplase is better than urokinase, hs-CRP, IL-1beta and IL-6 can be used to monitor the thrombolysis efficacy of APE patients
ABSTRACT
Objective To investigate the expression difference of microRNA -21 (miRNA-21) in patients with chronic cardiac function and analyze its clinical significance. Methods Patients with chronic heart failure (trial group,150 cases) and the subjects without chronic heart failure (control group,45 cases) were enrolled. Patients with chronic heart failure were divided into three subgroups according to NYHA: group A (heart function classⅡ,49 cases),group B (classⅢ, 51 cases) and group C (class Ⅳ, 50 cases). miRNA-21 levels were detected by qRT-PCR method. The levels of B type natriuretic peptide urea (BNP),left ventricular end diastole diameter (LVEDD) and left ventricular ejection fraction (LVEF) were determined. Results miRNA-21 expression in patients with heart failure were higher than that of control group (P < 0.01),and miRNA-21 expression in group C was higher than that of group A.Correlation analysis showed that there was a positive correlation between expression of BNP (r = 0.763,P < 0.01), LVEDD (r = 0.691,P<0.01), and the level of miRNA-21 in patients with chronic heart failure.And a negative correlation between LVEF value and the level of miRNA-21 (r = -0.918,P < 0.01). Conclusion miRNA-21 might be a potential marker for diagnosis of heart failure and could be a basis for reference about prognosis evaluation.
ABSTRACT
Objective To investigate the relationship between microalbuminuria to estimated glomerular filtration rate (mALB/GFR) ratio and incidence of contrast induced nephropathy (CIN) after underwent percutaneous coronary intervention (PCI). Between March 2010 to August 2011, a total of 137 patients who underwent PCI were selected. Anthropometric measures, lipid profiles, fasting blood glucose, CRP, base creatinine and microalbuminuria were measured before operation. Glomerular filtration rate was calculated by MDRD formula. Contrast volume (CV) was recorded after the operation for each patient. Serum creatinine was measured 24 h, 48 h, 72 h after operation, respectively. CIN was defined as an increase in serum creatinine levels of 25% or 44 μmol/L or more from baseline within 72 h after PCI. All patients were divided into group A (CIN group) and group B (No CIN group). Results Eighteen (13.1%) patients developed CIN(group A). The others were group B (no CIN group). The level of CRP, base creatinine, microalbuminuria and mALB/GFR in group A were significantly higher than that in group B ( P < 0 . 01 ) . GFR in group A was lower than that in group B (P < 0.05). Logistic regression analysis indicated that the level of base creatinine , microalbuminuria GFR and mALB/GFR were independent risk factors of CIN occurrence (P < 0.05). The receiver-operator characteristic curve analysis indicated that a mALB/ GFR ratio of 1.17 was a fair discriminator for CIN,and sensitivity were 94.1%, specifity were 72.5%. Conclusion A mALB/ GFR ratio was a independent predictor of CIN after PCI.

A Cleanert Alumina-N-SPE column (0.5 g/6 mL) chromatograpy with 5 mL of chloroform-methanol (7: 3) as eluent, instead of aluminum oxide column (100-200 mesh, 5 g, 1 cm) chromatograpy eluted successively with chloroform and the chloroform-methanol (7:3) (20 mL each), was applied to enrich matrine and oxymatrine in Sophora flavescens. Also, the optimization of the HPLC determination conditions with acetonitrile-ethanol absolute-3% phosphoric acid solution (84: 6: 10) as mobile phase, instead of acetonitrile-ethanol absolute -3% Phosphoric acid solution (80: 10: 10) recorded in Chinese Pharmacopoeia 2010 Edition, was more suitable for determination of matrine and oxymatrine in S. flavescens. This method has advantage of reducing sample handling time and solvent volume and increasing the accuracy and feasibility, which can simplify the procedure for determination of matrine and oxymatrine in S. flavescens.

<p><b>OBJECTIVE</b>To determine the efficacy of different antiretroviral drug regimens in mother to child HIV transmission prevention (PMTCT) in China.</p><p><b>METHODS</b>From January 1st 2006 to Dec 30th 2008, a total of 1072 pairs of HIV positive pregnant women and their babies who were HIV antibody positive and older than 18 months were recruited in this study. These women who had received maternal health care in health care institutions were from 23 provinces. Subjects were investigated by questionnaire, including social demographic data, usage of ARVs, safe delivery and artificial feeding, and other PMTCT related informations. The trend of different antiretroviral drug regiments in different period were analyzed by Cochran-Mantel-Haenszel (CMH) χ(2) test. By stratified analysis and Fisher exact χ(2) test, the efficacy of different antiretroviral drug regimens in mother to child HIV transmission prevention were studied. Antiretroviral drug regimens applications mainly included sd-NVP drug regimen, prophylaxis regimen and highly active anti-retroviral therapy (HAART).</p><p><b>RESULTS</b>Among 1072 pairs of HIV positive maternities and babies, 31 babies older than 18 months were HIV infected, MTCT rate was 2.9% (31/1072). (1) The proportion of using ARVs was increasing from 76.4% (306/395) in 2006 to 83.8% (372/444) in 2008, the difference was significant (CMH χ(2) = 6.4, P < 0.05). (2) The ratio that HIV infected maternities adopted ARVs rose from 3.4% (6/178) in 2006 to 26.3% (104/395) in 2008, the ratio increased year by year (CMH χ(2) = 53.1, P < 0.01). On the contrary, usage of sd-NVP declined from 88.8% (158/178) in 2006 to 70.9% (264/372) in 2008 (CMH χ(2) = 48.5, P < 0.01).

<p><b>OBJECTIVE</b>To explore the impact of being informed of HIV infection before or after pregnancy on the prevention of mother-to-child transmission (PMTCT) HIV interventions uptake.</p><p><b>METHODS</b>From 2005 to 2009, a tatal of 5552 HIV-infected pregnant women and their 5894 pregnancies in Henan, Guangxi, Yunnan and Xinjiang province were investigated using the method of a cohort study. The social-demographic characters (the objects were divided three age groups 15-, 25-, 35-49), the period identified to be HIV positive, the outcome of pregnancy and the PMTCT interventions including uptake of antiretroviral drugs (ARVs) were investigated. Through single-factor and non-conditional logistic regression model, the factors influencing the utilization of PMTCT services were analyzed.</p><p><b>RESULTS</b>Of HIV-infected pregnant women, 84.5% (4979/5894) were under 35 year-old, and 56.0% (3108/5552) of them were Han group and the percentage of peasant or unemployment was 85.1% (4727/5552). 86.8% (4815/5552) of these women had junior high school education or less, and the proportion of women knowing HIV infection before the pregnancy was 31.2% (1836/5894). Of HIV positive pregnant women, 31.7% (1869/5894) chose to terminate the pregnancy artificially, and the percentage was 43.8% (805/1836) among those knowing HIV infection before pregnancy. The proportion of the ARVs uptake among HIV positive maternities who delivered was 80.0% (3046/3808), while the percentage among those knowing HIV positive before pregnancy was 92.3% (883/957), which was much higher than it (75.9% (2163/2851)) among the pregnant women knowing HIV infection just during the pregnancy (χ(2) = 120.39, P < 0.05). The results of multivariate analysis showed that the proportion of ARVs' uptake was high among those HIV positive pregnant women knowing to be HIV-infected before pregnancy (versus knowing to be HIV-infected after the pregnancy, OR = 3.91 (95%CI: 3.03 - 5.05)) and age of 15 to 24 year-old (versus age of 35 - 49 year-old, OR = 0.75 (95%CI: 0.57 - 0.98)).</p><p><b>CONCLUSION</b>It will promote the HIV-infected pregnant women to receive the PMTCT intervention services if they know their HIV sero-status before pregnancy.</p>

The residual urine were compared before and after treatment in the two groups; the effective rate for improvement of symptoms were compared between the two groups. The mental and healthy nursing were conducted for the patients.</p><p><b>RESULTS</b>After treatment, the improving rate for the urgency of urination, frequency of micturition, dribbling urination, urinary incontinence and dysuria in the treatment group was significantly better than that in the control group, but with no significant difference between the two groups in prolongation of urination time. After treatment, the residual urine in the bladder significantly improved in the two groups with more significantly improved in the treatment group than in the control group.</p><p><b>CONCLUSION</b>Methycobal plus acupuncture has a better result than the simple Methyeobal for treatment of diabetic neurogenic bladder, and strengthening nursing care in the treatment can significantly enhance life quality of the patient.</p>

Objective To explore the effect of different method in preventing broncho-pulmonary dysplasia(BPD) in very low birth weight infants(VLBWI) during mechanical ventilation.Methods The gestational age of 71 infants with VLBWI was (30?2) weeks and the average weight was (1235.2?160.6)g.The infants were randomly divided into three groups,they received different therapeutic regimens during mechanical ventilation:32 cases were treated with permissive hypercapnia(PHC) ventilation in group Ⅰ;20 cases were treated by intratracheal instillation of pulmonary surfactant(PS) in group Ⅱ;19 cases were treated by inhalation of becotide(beclomethasone dipropionate,BDP) in group Ⅲ.The ventilator settings,blood gas analysis,clinical symptoms and therapeutic effect were statistically analyzed and compared.Results The peak inspiratory pressure(PIP) and ventilation rate(VR) of ventilator parameter were (18.3?1.6)cmH_2O and (35?5)bpm in group Ⅰ,there was significantly lower than that in group Ⅱ and group Ⅲ(P0.05).The incidence of BPD was 16%(5/32) in group Ⅰ,5%(1/20) in group Ⅱ and 5%(1/19) in group Ⅲ;The mortality rate of PHC group(group Ⅰ) was 6%(2/32) and 5%(1/20) in group Ⅱ.Conclusion The application of permissive hypercapnia,intracheal instillation of pumlonary surfactant and inhalation of becotide all can prevent effectively the occurrence of severe broncho-pulmonary dysplasia in VLBWI during mechanical ventilation.
ABSTRACT
Objective To investigate the anti-mutation of Chinese medicinal herb Herba Leonuri and its effect on T lymphocyte proliferation in spleen.Methods The micronucleus test of mouse bone marrow cell(MNT) :thirty mice were divided into six groups(n= 5),negative control(NS),cyclophosphamide group(CP 3.0 mg?kg-1),Herba Leonuri antimutagenesis groups(Herba Leonuri with dosages of 1.0,2.0,4.0,8.0 g?kg-1+CP30 mg?kg-1).The improved method was used to detect the micronuclei frequency.Lymphocyte transformation test:twenty-four mice were divided into four groups(n=6),saline control,CP control(30 mg?kg-1),Herba Leonuri(2.0 g?kg-1),Herba Leonuri +CP(2.0 g?kg-1 Herba Leonuri +CP 30 mg?kg-1).MTT assay was used to calculate the stimulation index(SI).Results The micronuclei frequencies in Herba Leonur 2.0,4.0,8.0 g?kg-1 groups were lower than that in CP group(P
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effects of total flavonoids of Hippophae rhamnoides L. (TFH), quercetin (Que) and isorhamnetin (Isor) on the intracellular free calcium ([Ca(2+)](i)) in vascular smooth muscle cells (VSMC) of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY).</p><p><b>METHODS</b>Fluo 3-acetoxymethylester (Fluo-3/AM) was used to observe the effects of TFH (100 mg/L) and its essential monomers, namely Que (10(-4) mol/L) and Isor (10(-4) mol/L) on changes of [Ca(2+)](i) in cultured SHR and WKY VSMC (abbr. to Ca-SHR & Ca-WKY) following exposure to high K(+), norepinephrine (NE) and angiotensin II (Ang II), and to compare with the effects of verapamil (Ver).</p><p><b>RESULTS</b>(1) TFH, Que and Isor had inhibitory effects on resting Ca-SHR (P < 0.05), but had no significant effects on Ca-WKY (P > 0.05). (2) High K(+) could increase Ca-SHR more significantly than Ca-WKY (P < 0.05); TFH, Que and Isor could inhibit the elevation of [Ca(2+)](i) induced by high K(+)-depolarization, with the effects similar to that of Ver, and the effect on Ca-SHR was more significant than that on Ca-WKY (P < 0.05). (3) NE and Ang II could increase Ca-SHR more significantly than Ca-WKY (P < 0.05), TFH, Que and Isor had remarkably inhibitory effect on the elevation of Ca-SHR and Ca-WKY induced by NE or Ang II. (4) In the absence of extracellular Ca(2+), TFH, Que and Isor also had certain inhibitory effect on Ca-SHR and Ca-WKY induced by NE, and the effect on the former was more significant than that on the latter (P < 0.05).</p><p><b>CONCLUSION</b>TFH, Que and Isor might decrease the levels of [Ca(2+)](i) in VSMCs by blocking both voltage-dependent calcium channels (VDC) and receptor-operated calcium channels (ROC) in physiological or pathological state, which may be one of the important mechanisms of their hypotensive and protective effects on target organs in patients with hypertension.</p>
