Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Objective: The main ingredients and the inhibitory effects of essential oil of a compound Chinese herbal medicine Weiqi Decoction (WQD) on AGS cell proliferation were to be investigated. Methods: Chemical compounds of WQD essential oil were detected by gas chromatography and mass spectrometry analysis. Cell viability was measured by methyl thiazolyl tetrazolium method. Cell cycle distribution was detected by flow cytometry. Apoptosis and necrosis of AGS cells were determined by Hoechst 33342/propidium iodine staining. Results: Chemical analysis showed that the main ingredients of WQD essential oil were bornylene and 3-n-butylphthalide. Ligustilide, which is the effective compound of Danggui (Radix Angelicae Sinensis), was not detected in WQD essential oil. The essential oil inhibited cell proliferation in a dose- and time-dependent manner, and blocked cell cycle progression at G(2)/M stage. At the concentrations that resulted in significant inhibition of cell proliferation and cell cycle arrest, essential oil induced both apoptosis and necrosis. Conclusion: The results suggest that WQD essential oil contains some effective ingredients for treating chronic atrophic gastritis and functional dyspepsia, and also has an antiproliferative effect on AGS cells through cell cycle arrest and apoptosis promotion in vitro. Therefore, essential oil should be retained as much as possible during stewing this decoction.

In this study, we evaluated the difference ot biological characteristics in the MERS-CoV infected mice model in prior to transduction with different dosage of human DPP4. Firstly, we transduced different dosage of DPP4 (high or low) into mice, and then challenged them with MERS-CoV in order to establish the model. After establishment of mice model, we observed the clinical signs of disease, virus replication, immunopathogenesis and antibody response. The results indicated that the infected mice showed typical pneumonia, virus replication, histological lesions, and neutralizing antibody production. Moreover, the high dosage group was superior to the low dosage group. Fourteen days after infection, the specific antibody to virus structural protein and neutralizing antibody were analyzed, the high dosage group induced higher level antibody. In summary, the MERS-CoV infected mice model were established prior transduction with DPP4, and the level of DPP4 influenced the clinical signs of disease, virus replication and antibody response in this model.

OBJECTIVETo evaluate the effects of the ethanol extract isolated from Weiqi Decoction (WQD-EE) on AGS cell proliferation and apoptosis.

METHODSBy using high-performance liquid chromatography with ultraviolet detectors (HPLC-UV) assay and MTT method, the main compounds in WQD-EE and cell viability were detected. And cell cycle distributions were determined by flow cytometry with propidium iodine (PI) staining while apoptosis was detected by flow cytometry with annexin V/PI double staining. Finally, caspase-3 activities were measured by colorimetric method and protein expression was determined by Western blotting.

RESULTSHPLC analysis showed that naringin (35.92 μg/mg), nobiletin (21.98 μg/mg), neohesperidin (17.98 μg/mg) and tangeretin (0.756 μg/mg) may be the main compounds in WQD-EE. WQD-EE not only inhibited AGS and MCF 7 cell proliferation in a dose-dependent manner, but also blocked cell cycle progression at G2/M stage as well as inducing cell apoptosis at concentrations triggering significant inhibition of proliferation and cell cycle arrest in AGS cells. While at 0.5 mg/mL, WQD-EE significantly increased caspase-3 activity by 2.75 and 7.47 times at 24 h and 48 h, respectively. Moreover, WQD-EE in one hand reduced protein expressions of p53 and cyclin B1, and in other hand enhanced protein expressions of cytochrome c and Bax. Protein levels of Bcl-2, Fas L and Fas were not significantly affected by WQD-EE.

CONCLUSIONSWQD-EE inhibits AGS cell proliferation through G2/M arrest due to down-regulation of cyclin B1 protein expression, and promotes apoptosis by caspase-3 and mitochondria-dependent pathways, but not by p53-dependent pathway.

OBJECTIVETo study the effects and immunoregulation mechanism of the traditional Mongolian medicine Wuweifengshi capsule on adjuvant arthritis (AA).

METHODWister rats were divided into several groups: normal group, AA model group, Wuweifengshi capsule groups (with low, moderate, high dose of 0.2, 0.4, 0.8 g x kg(-1) x d(-1) respectively), and Zhonglun-5 group (original dose of 1.68 g x kg(-1) x d(-1)). The edema degree, the level of IL-1beta, TNF-alpha, PGE2, NO and MDA and the activity of SOD in serum were detected. Through cell culture, the effects of the medicine on AA rat's splenic cell's multiplication capacity were studied. The influence of celiac macrophage cell culture fluid of AA rats' on C57BL/6J mice thymic cell multiplication capacity under the medicine was evaluated.

RESULTWuweifengshi capsule showed an inhibiting function on the level of IL-1beta, TNF-alpha, PGE2, NO and increased the activity of SOD in serum, but showed no significant influence on MDA. It also inhibited the AA rat's splenic cell's multiplication capacity and the influence of celiac macrophage cell culture fluid of AA rat's on C57BL/6J mice thymic cell multiplication capacity.

CONCLUSIONThe anti-AA effect of Wuweifengshi capsule is possibly due to its inhibition of relevant cytokines and its adjustment of corresponding enzyme's activity and immunization organ's cell multiplication capacity.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eighty-two colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P=0.011). The patients with IL10 rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P=0.007) and in multivariate Cox regression model (P=0.044) adjusting for age, gender, carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion, and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.

OBJECTIVESTo study clinical characteristics and outcome of pure red cell aplasia (PRCA) following major ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSVariables including sex, age, stem cell source, granulocyte engraftment time, blood transfusion and isoagglutinin type against donor RBC were analyzed to identify risk factors for the development of PRCA.

RESULTSTwelve of 100 patients received major ABO-incompatible allo-HSCT developed PRCA, with out any effect on incidence of aGVHD and CMV infection. ABO blood groups of recipient/donor pairs of these twelve PRCA patients were O/A in nine, B/A in one and O/B in two. Patients with anti-A isoagglutinins against donor RBC developed PRCA more frequently than those with anti-B (10/49 vs 2/49). Median duration to the recovery of erythropoiesis tended to be longer in patients with PRCA (PRCA vs non-PRCA, 203.5 vs. 76 days, P < 0.05 ). Median durations to the disappearance of incompatible isoagglutinins tended to be longer in patients with PRCA (PRCA vs. non-PRCA, 150.5 vs. 60 days,P <0.05) and in those with anti-A isoagglutinins (anti-A vs anti-B, 90 vs 55 days, P < 0.05).

CONCLUSIONABO blood group of O/A in recipient/donor pair was the only high risk factor for PRCA after major ABO-incompatible allo-HSCT.

OBJECTIVETo investigate the effect of local application of bFGF and sucralfate during continuous tissue expansion (CTE).

METHODSCTE combined with local administration of bFGF and sucralfate was used in twelve patients with scar and nasal tip defects. Twenty three expanders were placed in the subcutaneous pockets through intralesion short incisions. Continuous expansion began at 1-3 days after expander implantation. The histomorphological changes and epidermal cell proliferation were observed. The clinical results were investigated.

RESULTSThe average inflation time was 8.9 days. The average interval of the two operations was 13.5 days. The average hospitalization was 28.4 days. The average immediate stretch-back rate of the expanded skin was 25.7%. The clinical results were satisfactory without any complications. Histological examinations showed that the epidermal, granular and spinous layer became thicker. The basal cells increased significantly. The dermis thinned slightly and the collagen fibers became thicker. The elastic fiber regenerated significantly. Fibroblast and capillary density increased obviously. The immunohistochemistry analysis showed that the proliferation of epidemic basal cells was significant postoperatively.

CONCLUSIONLocal application of exogenous bFGF and sucralfate during CTE was feasible in patients. It could accelerate tissue expansion and improve the quality of expanded skin flap.

[Objective]To investigate the diagnostic value of quantitative perfusion parameters of dynamic contrast-enhanced im?aging for discriminating metastatic from non-metastatic regional lymph nodes in rectal cancer.[Methods]122 patients of our depart?ment were collected from 2015.01 to 2016.08, and 203 lymph nodes, including metastatic lymph nodes (MLNs, n=95) and non-meta?static lymph nodes (NMLNs, n=108), were analyzed. The short-axis diameter (S), long-axis diameter (L), short-to long-axis diameter ratio (S/L), volume transfer constant (Ktrans), rate constant (Kep) and extravascular extracellular space (EES) fractional volume (Ve) were compared between two groups respectively. Then using S=5 mm as a cutoff value, these parameters were compared between subgroups. Receive operating characteristic curve (ROC) was used to analyze the diagnostic efficiency and find the optimal cutoff values.[Re?sults]The metastatic group exhibited higher S and L, but lower S/L, Ktrans and Kep than the non-metastatic group (P<0.01). However, the Ve did not differ significantly between two groups (P=0.308). Optimal cutoff values [area under the curve (AUC), sensitivity, speci?ficity] of Ktrans for discriminate metastatic lymph nodes from non-metastatic were 0.088 min-1 (0.69, 58.3%, 78.9%). When S>/=5 mm, subgroup analysis revealed that Ktrans and Kep of MLNs were significant higher than those of NMLNs (P<0.001), but Ve was lower (P=0.039). Optimal cutoff values (AUC, sensitivity, specificity) of Ktrans were 0.088 min-1 (0.675, 57.1%, 77.9%). However, when S<5 mm, MLNs showed lower Ktrans than NMLNs (P=0.001), but there were no significantly statistic differences of Kep and Ve between these two groups (P>0.1). Optimal cutoff values (AUC, sensitivity, specificity) of Ktrans were 0.087 min-1 (0.732, 60.5%, 81.5%).[Conclusion]Ktrans can be used to discriminate regional MLNs from NMLNs in rectal cancer, especially when the short-axis diameter is less than 5 millimeters.
