OBJECTIVE: To explore the effect of WDSUB1 on dextran sulfate sodium (DSS)-induced inflammatory colon injury in mice and the underlying mechanism. METHODS: Different WDSUB1 siRNA sequences were transfected into mouse fibroblast L929 cells and the optimal sequence was selected by Western blotting. Twelve male C57BL/6 mice were randomized into two groups for injection of siWDSUB1 or siControl via the caudal vein, followed by treatment with 2.5% DSS in drinking water to establish mouse models of DSS- induced colitis (n=6). The expression level of WDSUB1 in the colon tissue of the mice was detected with Western blotting and RT-PCR, the changes in body weight and fecal condition were recorded, and the clinical symptoms of the mice were evaluated. The mRNA expression levels of IL-6, COX-2 and TNF-α and the protein expression of IκBα and P65 in the colon tissues were detected with RT- PCR and Western blotting, respectively. RESULTS: The mRNA and protein expressions of WDSUB1 in the colon tissues were significantly lower in colitis mice with WDSUB1 knock-down than in the control mice. Compared with the control mice, the mice receiving siWDSUB1 injection showed obviously milder weight loss, diarrhea and hematochezia with significantly lower mRNA expressions of COX2, IL-6 and TNFα (P < 0.05) and protein expression of IκBα but without obvious changes in P65 expression in the colon tissue. CONCLUSION WDSUB1 knockdown can alleviate DSS- induced colitis in mice possibly by inhibiting the NF-κB signaling pathway and decreasing the expression of inflammatory factors in the colon tissues.

Based on the network target approach and technology, this study proposed for the first time a novel optimization method for Chinese medicine formulae. Moreover, with Qingluo Decoction as an example, a method for the research and development of Chinese medicine, which combines scientific methodology and experience of famous doctors, was developed. Specifically, based on the composition of Qingluo Decoction, this study used the using network target for intelligent and quantitative analysis on drug actions(UNIQ) to predict the medicinals that targeted the key pathways of rheumatoid arthritis(RA) such as angiogenesis. Then, combining the experience of the first national Chinese medical master LI Ji-ren and Aihui famous Chinese medicine doctor LI Yan and Chinese medicine theory, this study developed a novel angiogenesis-targeted prescription modified Qingluo Decoction(MQLD). Afterward, the clinical efficacy and mechanism of MQLD were verified. The results showed that 27 medicinals with significant regulatory effect on angiogenesis-related key signaling pathways were identified by UNIQ, among which 6 were selected by the Chinese medicine physicians to develop the MQLD. Clinical trials demonstrated that the clinical efficacy of MQLD, in terms of either American College of Rheumatology 20% improvement and 50% improvement criteria(ACR20, ACR50) or TCM syndrome evaluation, was better than that of Qingluo Decoction. Experimental study revealed that MQLD can inhibit RA angiogenesis by acting on the vascular endothelial growth factor(VEGF) pathway, nuclear factor κB(NF-κB) pathway, inflammatory cytokine release, and immune cell regulation. Taken together, this study developed a new formula MQLD with improved clinical efficacy, precise applicable clinical settings, and authorized patent through the network target technology, thus providing a new way for the precise development of Chinese medicine and preservation of the experience of famous physicians.

OBJECTIVE: To analyze the preservation effect and related influencing factors of human peripheral blood mononuclear cells under serum-free condition at 4 ℃. METHODS: Human peripheral blood mononuclear cells were isolated by density gradient centrifugation, and stored at 4 ℃ under different cell concentrations, supplemented with human serum albumin, and glucose. The cell viability, total cell number, viable cell number and cell phenotype were detected during preservation of 72 h. RESULTS: With the prolongation of storage time, the number of human peripheral blood mononuclear cells gradually decreased(r=0.982). Compared with the cell concentration of (5-6)×10⁶ cells/ml, the cell number decreased more slowly when the cell storage concentration was (1-2)×10⁶ cells/ml; Adding human serum albumin and glucose can effectively improve the survival rate of human peripheral blood mononuclear cells, among which 2% human serum albumin has a better preservation effect; Compared with the blank control group, the analysis results of cell subsets showed that the downward trends of NK cells and T cells were significantly slowed after adding albumin and glucose. CONCLUSION The cell density of (1-2)×10⁶/ml and 2% human serum albumin are more suitable for the preservation of PBMC, and 5% glucose can improve the preservation effect of human peripheral blood mononuclear cells at 4 ℃.

Objective: To investigate the impact of change of ideal cardiovascular behavior and related factors on healthy vascular aging(HVA). Methods: This study was a multi-center cross-sectional survey. Six thousand three hundred and sixteen participants who underwent at least 2 healthy examinations from 2006 to 2015 at 11 hospitals, including Kailuan Hospital and so on, and examined brachial-ankle pulse wave velocity (baPWV) during 2010 and 2016, with available information about cardiovascular behavior and factors were included. The cardiovascular health score (CHS) was calculated. Basic CHS was collected from the first examination. The second CHS derived from the healthy examination in the same year of baPWV examination. Change of cardiovascular health score (ΔCHS) was calculated. Participants were defined into 5 groups according to ΔCHS, namely ΔCHS≤-2 (n=2 166), ΔCHS=-1 (n=1 284), ΔCHS=0 (n=1 187), ΔCHS=1 (n=860), and ΔCHS≥2 (n=819). Participants' characteristics, value of baPWV and proportion of HVA were compared among different groups. Multiple logistic regression analysis was used to investigate the association between ΔCHS and HVA. The ΔCHS was recalculated and included in multiple logistic regression analysis model again after each component of the cardiovascular health metrics was removed separately in order to investigate effects of removal factors on HVA by observing changes in effect values. Results: The percentage of the participants with HVA in the group of ΔCHS≤-2, ΔCHS=-1, ΔCHS=0, ΔCHS=1 and ΔCHS≥2 were 23.3%(505/2 166), 27.8%(357/1 284), 28.7%(341/1 187),31.9%(274/860) and 33.9%(278/819), respectively. After adjustment for age, sex, income, education, alcohol consumption and the basic CHS, a significant positive association between ΔCHS and proportion of participants with HVA was observed (OR=1.50, 95%CI 1.44-1.56). Multiple regression analysis after removing each single cardiovascular behavior or factor showed that the OR value decreased as follow systolic blood pressure (OR=1.04, 95%CI 1.00-1.09), fasting blood glucose (OR=1.14, 95%CI 1.09-1.18), physical exercise (OR=1.16, 95%CI 1.11-1.21), salt intake (OR=1.17, 95%CI 1.12-1.22), body mass index (OR=1.18, 95%CI 1.13-1.23), smoking(OR=1.18, 95%CI 1.13-1.23) and total cholesterol (OR=1.20, 95%CI 1.16-1.24). Conclusion: The improvement of every ideal cardiovascular behavior and factor is associated with the increase of the proportion of HVA population.

Food intake has a great influence on blood glucose in patients with diabetes.This study was to determine the glycemic index (GI) and glycemic load (GL) of a particular pomelo named Majia pomelo and its effects on postprandial glucose (PPG) in patients with type 2 diabetes (T2D).Twenty healthy subjects and 20 T2D patients (controlled on lifestyle measures and/or metformin) were tested on 2 separate days with 50 g of glucose and 50 g equivalent of carbohydrates from Majia pomelo for GI measurement.To test effects of Majia pomelo on PPG,19 hospitalized T2D patients (controlled on insulin therapy) were selected for a 9-day study.The dose of insulin for each patient was adjusted on the first 3 days.A total of 100 mg Majia pomelo was consumed per meal in the last 3 tested days.Blood glucose was measured to evaluate the glycemic excursions.The GIs for Majia pomelo in healthy individuals and T2D patients were 78.34± 1.88 and 72.15±1.95 respectively.The value of GL was as low as 4.23 in diabetic patients with serving size of 100 g pomelo,indicting Majia pomelo as a high GI but low GL fruit.Consumption of Majia pomelo in hospitalized T2D patients did not cause significant glucose fluctuation.It was concluded that high GI pomelo can serve as a low GL fruit if it is consumed with a limited daily amount and thus can be supplied to diabetic patients.These results may mean more varieties of food choices for T2D patients.

OBJECTIVETo investigate the correlations between vessel changes and the histopathologic subtypes of lung adenocarcinoma with pure ground-glass nodule (pGGN) on computed tomography (CT).

METHODSTotally 107 patients (116 lesions) with lung adenocarcinomas with pGGN who had undergone curative resection were included. Vessel changes included vascular convergence and/or vessel dilation or distortion within the pGGN. According to the vessel appearances within the pGGN, all patients were categorized into two groups: no change group and change group. Pearson chi-square test was used to analyze the relationships between vessel changes and histopathologic subtypes. Mann-Whitney rank test and t-test were used to identify the relationship of vessels changes with pGGN density and diameter.

RESULTSAmong these 116 pGGNs, there were 21 without vessel changes and 4 with vessel changes in 25 preinvasive lesions; 14 without vessel changes and 15 with vessel changes in 29 minimally invasive adenocacinomas; 16 without vessel changes and 46 with vessel changes in 62 invasive lung adenocarcinomas. There were statistically significant differences of vessel changes (P=0.000) among histopathologic subtypes. The lesion diameter was significantly different between these two groups (P=0.000), while the lesion density showed no significant difference (P=0.826).

CONCLUSIONVessel changes may indicate the invasiveness of lung adenocarcinoma with pGGNs and are related with the lesion diameter.

BACKGROUNDThere remains significant debate as to the relationship between fragmented QRS (fQRS) complexes on electrocardiogram (ECG) and acute myocardial infarction (AMI). Few studies have reported on this relationship in non-ST elevated AMI (NSTEMI), and thus, we attempt to assess this relationship and its potential short-term prognostic value.

METHODSThis was a single-center, observational, retrospective cohort study. A total of 513 consecutive patients (399 men, 114 women) with NSTEMI within 24 h who underwent coronary angiography at our department, between January 1, 2014, and December 31, 2014. Patients were divided into 2 groups according to the presence or absence of fQRS complex on the admission ECG. fQRS complexes were defined as the existence of an additional R' or crochetage wave, notching in the nadir of the S wave, RS fragmentation, or QS complexes on 2 contiguous leads. All patients were followed up for 6 months, and all major adverse cardiac events (MACE) were recorded.

RESULTSIn this study, there were 285 patients with fQRS ECG in the 513 patients with NSTEMI. The number of patients with 0-2 coronary arteries narrowed by ≥50% in fQRS group were less while patients with 3 narrowed arteries were more than in the non-fQRS group (P = 0.042). There were fewer Killip Class I patients in the fQRS group (P = 0.019), while Killip Class II, III, and IV patients were more in the fQRS group than in the non-fQRS group (P = 0.019). Left ventricular ejection fraction levels were significantly lower in the fQRS group (P = 0.021). Baseline total cholesterol, low-density lipoprotein, creatinine, creatine kinase, homocysteine, high-sensitivity C-reactive protein (CRP), and red blood cells distribution width levels were significantly higher in the fQRS group. Total MACE (MACE, P = 0.028), revascularization (P = 0.005), and recurrent angina (P = 0.005) were also significantly greater in the fQRS group. On final logistic regression analysis, after adjusting for baseline variables, the following variables were independent predictors of fQRS: Coronary artery narrowing (P = 0.035), Killip classification (P = 0.026), and total cholesterol (P = 0.002). The following variables were found to be independent predictors of preoperative MACE: Hemoglobin (P = 0.000), gender (P = 0.026), fQRS (P = 0.016), and time from myocardial infarction to balloon or coronary artery bypasses grafting (P = 0.013).

CONCLUSIONSThe fQRS complexes are commonly present in NSTEMI and the fQRS complexes are an independent predictor of MACE in NSTEMI patients. The number of narrowed coronary arteries, Killip classification, and total cholesterol are all independent predictors of the fQRS complexes.

OBJECTIVETo evaluate the effect of adjuvant hormonal therapy (AHT) immediately after radical surgery for high- risk organ-confined or locally advanced prostate cancer using the PSA-related biochemical relapse rate within 2 years after surgery.

METHODSWe retrospectively analyzed 62 cases of high-risk organ-confined or locally advanced prostate cancer. The patients were treated by laparoscopic radical prostatectomy or radical retropubic prostatectomy after MRI and ECT systemic bone imaging examination, which revealed no regional lymph node or bone metastasis. Thirty-two of the patients (group A) received AHT orally or subcutaneously from 2 weeks to 1 months after operation, and another 30 (group B) were left untreated. We followed up the patients for 2 years, measuring the serum PSA level every 3 months, performing ECT every 6 months, and recording the adverse reactions, medication dura- tion, and the patients'quality of life.

RESULTSAll the operations were successfully accomplished. The rate of 2-year biochemical relapse-free survival was 78.13% (25/32) in group A and 53.33% (16/30) in group B.

CONCLUSIONAHT immediately after radical surgery can improve the rate of biochemical relapse-free survival of the patients with high-risk organ-confined or locally advanced prostate cancer and check the progression and metastasis of the disease.

BACKGROUNDAlthough it was widely accepted that full-length HIV genome sequences is important in studying virus genetic evolution and variation as well as developing vaccine candidate, to directly sequencing HIV-1 genome of virion RNA remains as a challenge worldwide. Up to date, no published genomic sequences from virion RNA are available for Chinese prevalent HIV-1 strains due to the absence of specialized protocol and appropriate lab equipments. In this study we developed a straightforward approach for amplifying and sequencing HIV virion RNA from plasma by modifying published protocols and further confirmed it is suitable to process Chinese samples.

METHODSThe methods for viral RNA extraction and gene amplification was modified and optimized as could be widely used in most Chinese labs. Gene alignment of Chinese HIV-1 strains was employed for designing specialized primer sets for Thai-B and BC recombinant strains. Based on comprehensively consideration of high variable gene region and recombinant breakpoints in BC recombinant strains, a three-amplicon strategy (including 4.3-kb gag-pol, 2.9-kb pol-env and 2.7-kb env-nef) was developed. In addition, one amplicon (9 kb near full-length genome) was also used in 32 samples with varied viral loads. All amplicons were directly sequenced by DNA automated sequencer.

RESULTSTwenty-five percent (8/32) amplification efficiency was achieved by the one-amplicon strategy and 65.6% (21/32) by three-amplicon strategy. For one amplicon strategy, none of complete near full-length genome sequences was obtained by DNA sequencing. For three-amplicon strategy, 75% sequences were achieved in DNA sequencing. Amplification efficiency but not sequencing efficiency was closely associated with viral loads.

CONCLUSIONThree-amplicon strategy covering all encoding regions of HIV-1 is suitable for Thai-B and BC recombinant strains and could be potentially employed in less-well equipped Chinese labs.
