Objective To study the bacteriostatic activity and stability of pine bark Oligomeric Proantho Cyanidins. Methods By the K-B disk diffusion method, spoilage bacteria as experiment strains, to study the inhibition effects of the pine bark Oligomeric Proantho Cyanidins and the antimicrobial stability under certain temperature, pH, and UV exposure time. Results Pine bark Oligomeric Proantho Cyanidins had significant inhibitory effect on Gram positive bacteria (Staphylococcus aureus and Bacillus Sukatilis), which had better inhibition effects in the media neutral, but temperature and UV had little influence on the antimicrobial effects. The minimum inhibitory concentration (MIC) of pine bark Oligomeric Proantho Cyanidins against Staphylococcus aureus and Bacillus Sukatilis were 12.5 and 6.25 mg/mL, respective. However, on Gram negative bacteria(Escherichia coli and Pseudomonas aeruginosa) there was no obvious inhibition effects. Conclusion The pine bark Oligomeric Proantho Cyanidins has significant inhibitory effect on Gram positive bacteria, the inhibitory effect is stronger in the range of pH 6-7 , and the temperature and UV had a little effect on its antibacterial action, which means that the antibacterial action of pine bark Oligomeric Proantho Cyanidins had good stability.

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

Clinically, atrial fibrillation (AF) is one of the most common cardiac arrhythmia, and patients with arterial fibrillation carry high risk of stroke. Oral administration of anticoagulation such as warfarin for the prevention of stroke has some risks to induce bleeding; moreover, some patients are not able to tolerate the medication. Percutaneous occlusion of the left atrial appendage is safe and effective for the prevention of stroke in patients with atrial fibrillation, although at present it is only used for the patients who have contraindications to anticoagulation medication. This paper aims to review a variety of left atrial appendage occlusion devices and to analyze the relationship between the different shape design of occluder and the left atrial appendage morphology.

Objective To explore colloidal gold method used to detect fecal occult blood tests(FOB)detection capability and establish the laboratory standard operation of detecting FOB limit of blank(LOB),limit of detection (LOD)and quantifica-tion limit (LOQ)according to the CLSI document《Evaluation of Detection Capability for Clinical Laboratory Measurement Procedures;Approved Guideline-Second Edition》(EP17-A2),in order to reduce the false negative rate of the weakly positive samples,and to provide a way of quantitative detection for qualitative detection of colloidal gold method.Methods Detected series of solution of hemoglobin made of dissolved fresh whole blood with the ELISA kit of human free hemoglobin,and es-tablished the standard curve of detection of FOB with colloidal gold method.Detected the blank samples and a series of low concentration samples with the colloidal gold test strip of FOB and measured the color bands by the Nato Checker710.The quantitative results obtained were statistically analysised by SPSS 1 9.0 and calculated blank limit,detection limit and quanti-fication limit.Results The LOB,LOD and LOD were 99.01,340.48 and 354.9 ng/ml according to the methods in CLSI EP1 7-A2 ducument.Conclusion The detection limits established by CLSI EP1 7-A2 document was more scientific in j udge-ment positive or negative to FOB than which used naked eye and can meet the clinical laboratory and clinical doctor require-ment better.Clinical laboratories should be strictly in detection limits of reagents in order to ensure their effectiveness,and should be generaly to other tests based on colloidal gold method.

Objective To summarize the clinical effect of Doty procedure on surgical treatment for patients with congenital supravalvular aortic stenosis (SVAS).Methods Between Jan.2009 and Jun.2013,12 cases of consecutive patients underwent surgical corrections of SVAS using Doty procedure.Among them,Williams' syndrome were present in 5 patients.Nine cases were male,and 3 cases were female.Mean age was(5.3 ±4.2) years(9 months to 12 years) and mean weight was (11.5 ± 5.3) kg (7.5-32.0 kg).Echocardiography and Computed Tomography confirmed the diagnosis.SVAS was discrete in 9 patients and diffuse in 3 patients.Mean peak preoperative gradient was 6.86-16.23 (11.07± 3.68) kPa,with 3 patients above 13.33 kPa.Bicuspid aortic valve was present in 2 patients,mild aortic valve stenosis in 1 patient,mild aortic regurgitation in 2 patients,1 patient with subaortic membrane,3 patients with stenosis of the left or the right pulmonary artery,1 patient with pulmonary valve stenosis,2 patients with PDA,moderate to severe mitral insufficiency in 1 patients.Surgery was performed using Doty procedure through median sternotomy with cardiopulmonary bypass.Results Mean time of cardiopulmonary bypass was (85 ± 26)min (68-129 min).Mean time of aortic clamp was (51 ± 16) min(43-68 min).There was no early death and low cardiac output syndrome.Mild ST segment change was present in 5 patients and occasional premature beat was in 3 patients.Ventilator was applied for 7 to 38 h and Cardiac Intensive Care Unit treatment was done for 1 to 4 d.The mean peak supravalvular gradient measured postoperatively was (2.18 ± 1.09) kPa.Follow-up data were available for 11 patients,ranged from 6 months to 3 years.The gradients across supravalvular were lower than 3.33 kPa,except for 2 patients with severe SVAS preoperatively.There was no late death,dizzy or palpitation during follow-up.Conclusion Doty produce for SVAS can get satisfactory clinical results.

Objective To explore the protective effect and mechanism of gardenoside on the damage of dopaminergic neurons induced by lipopolysaccharide (LPS). Methods Both neuron-enriched cultures and neuron-astrocyte cultures were pretreated with vehicle or gardenesides ( 10, 20 and 40 mg/L) for 30 min at 37℃. The culture media were subsequently renewed in order to remove gardenesides. LPS was then added into all culture media at a final concentration of 10 mg/L Twenty-four hours later, the culture media was collected to measure TNF-α, NO, IL-6, GDNF and MMP-9; the cells were collected to count the number of cells labeled with an antibody against tyrosine hydroxylase (TH) and to assess the expression of TH mRNA using reverse transcription-polymerase chain reaction. Results Gardeneside didn't promote the survival of dopaminergic neurons in neuron-enriched culture, but significantly increased the survival of dopaminergic neurons in neuron-astrocyte culture, compared with the vehicle group, the survival of dopaminergic neurons increased from 203.0%±17.4% to 256.7%±15.2% ( F = 17.22, P = 0.001 ) in 40 mg/L gardenaside group. The amount of TNF-α, NO and GDNF released from the neuron-astrocyte cultures after 24 h of addition of LPS was not changed significantly, while the expression of IL-6 and MMP-9 was increased significantly. In this study, the gardenoside concentration-dependently attenuated the LPSinduced increase of the expression of IL-6 and MMP-9, compared with the vehicle group, the expression of IL-6 and MMP-9 decreased to 67.2%±6.4% (F= 12.89,P =0.001 ), 77.3%±9.8% (F =8.27,P = 0.001 ) respectively in 40 mg/L gardenoside group. Conclusions Astrocytes play a neuroprotective role on dopaminergic neurons, which is decreased by LPS via inducing the secretion of pro-inflammatory factors. Gardeneside may protect dopaminergic neurons from LPS-induced injury in an astrocyte-dependent manner and it inhibits the production of proinflammatory factors instead of promoting the secretion of GDNF. From the point of view that a very low toxicity of gardenesides has been well documented, this report may reveal a new way of developing therapeutic interventions for inflammation-related diseases such as Parkinson's disease.

Objective To compare the X-ray features between Hirschsprung alied disease (HAD)and Hirschsprung disease ( HD), and analyze the differentiations. Methods From December 2004 to December 2009, nineteen cases of HAD, aged from 30 days to 10 years (median, 14 months), received barium enema examinations in our institution. Other 19 cases with HD, also received barium enema examinations, were chosen randomly. They were aged from 42 days to 8 years ( median, 8 months). The imaging features of HAD and HD were analyzed retrospectively. The incidence rate of colon stenosis,"truncation sign" and spasm notch and R/C ratio (the longest diameter of rectum/colon) were calculated and compared between these two groups. In all these cases, diagnosis was confirmed by postoperative histopathology. The position of barium retained was also evaluated. These parameters of both groups were compared by x2 and Fisher test. Results There was statistical significance in the incidence rate of colon stenosis between HAD (9/19) and HD (18/19) (x2 = 10.364, P ＜0.01). However, there was no statistical significance in "truncation sign" and spasm notch between HAD (4/19 and 3/19, respectively)and HD ( 1/19 and 1/19, respectively) (P ＞0. 05 for both). R/C ratio was 0. 42 ±0. 15 in HAD group and 0.29±0. 12 in HD group, and there was statistical significance between them (t =2.892,P＜0.01). In HAD group, barium retained in distal sigmoid colon in 1 case (1/19), in distal descending colon in 7 cases (7/19), in distal transverse colon in 1 case (1/19), in total colon in 6 cases (6/19); However, in HD group, barium retained in distal rectum in 3 cases (3/19), in distal sigmoid colon in 13 cases ( 13/19), in distal descending colon in 3 cases (3/19). Conclusions There were some differences in the imaging features between HAD and HD though they presented similar clinic experience. HAD cases presented a lower incidence rate of colon stenosis and a higher R/C ratio than HD cases. In HAD cases, the most common site of barium retained is distal descending colon, while in HD cases, it is distal sigmoid colon.

Objective To explore the change of serum osteopontin levels in preoperative and postoperative patients with non-small cell lung cancer (NSCLC) and its clinic significance.Methods The levels of serum osteopontin were detected by ELISA.Results In 88 NSCLC patients,serum osteopontin levels were significantly higher than in benign pulmonary disease and healthy control group(P＜0.05.P＜0.01.respectively) There was no difference between benign pulmonary disease and healthy control group(P＞0.05).Serum osteopontin levels were related to clinical stage and lymph node metastasis,and the levels of serum osteopontin were lower in postoperative patients than in preoperative cases(P＜0.05).For NSCLC.the detection of osteopontin had a sensitivity of 84.1%,a specificity of 92.5%,and an accuracy of 88.1%. Conclusion Increased serum levels of osteopontin may be useful as a helpful clinical biomarker to diagnose earlier,predict prognosis and differentiate from benign pulmonary disease.
