AIM: To evaluate the effect of flavored Siwu granules in the clinical adjuvant treatment for phlegm and blood stasis mutual junction retinal vein occlusion.
METHODS: Sixty patients (60 eyes) were randomly divided into treatment group and control group, both with retinal laser photocoagulation and intravitreal injection of triamcinolone acetonide, but the treatment group used flavored siwu granules. Vision, fundus change, fundus fluorescein angiography, clinical syndrome of traditional Chinese medicine ( TCM ), hemorheology examination and safety assessment were evaluated before and 8wk after treatment.
RESULTS: At 8wk after treatment, there were differences on vision improvement, retinal circulation time, whole blood low shear viscosity and total efficient rate of clinical syndrome of TCM, compared with control group(P<0. 05).
CONCLUSION: Flavored siwu granules adjuvant for phlegm and blood stasis mutual junction retinal vein occlusion can improve visual acuity and reduce the eye complications.

Objective: To chine and express the recombinant human endothelial monocyte-activating polypeptide-Ⅱ(EMAP-Ⅱ)and identify its anti-tumor biological activities.Methods: EMAP-Ⅱ_(147-312)was expressed by the expression vector pMAL-p2x and E.coli BL-21 and the product was purified.The production of tissue factor(TF)in human umbili- cal vein endothelial cell ECV-304 mediated by the recombinant EMAP-Ⅱwas determined by chemiluminescence sub- strate.The promoting effect of recombinant EMAP-Ⅱon TNF?-induced ECV-304 cell.Apoptosis was determined by flow cytometry.Its inhibitory effect on human pancreaic cancer cell SW1990 proliferation was determined by MTT method. Results:DNA sequencing verified that EMAP-Ⅱwas correctly cloned.The molecular mass of the protein identified by SDS-PAGE was consistent with the theoretic value.The productivity of recombinant EMAP-Ⅱwas 500?g per 1 g bacteria (wet mass).The purified product induced expression of tissue factor(TF)in ECV-304 cells;it also enhanced the sensi- tivity of ECV-304 cells to the apoptotic effect of TNF?([16.6?2.5]% vs[25.6?2.3]%,P

AIMTo investigate the effects of protein tyrosine kinase on the inflammation and airway remodeling in lung of guinea pigs with bronchial asthma.

METHODS30 adult male guinea pigs were randomly divided into 3 groups (n=3): control group (C group), asthmatic group(A group)and genistein group (B group). Asthmatic model was established by ovalbumin intraperitoneal injection and ovalbumin inhalation. The total cell and the proportion of inflammatory cell in bronchial alveolar lavage fluid(BALF), inflammatory cell infiltration and index of remodeling of bronchiole were measured, respectively. The expression of p-tyrosine in lung tissue was examined by immunohistochemistry.

RESULTSThe total cell and proportion of eosinophil in BALF of A group were significantly higher than that of C group (P < 0.01), but compared with A group, the total cell and proportion of eosinophil in BALF of B group were much lower (P < 0.01). The number of eosinophile and lymphocyte of bronchiole in A group were significantly higher than that of C group (P < 0.01), but compared with A group, the number of eosinophile and lymphocyte in bronchiole of B group were much lower (P < 0.01). Compared with A group, the remodeling of bronchiole of B group was significantly relieved (P <0.01), there was no difference between B and C group (P > 0.05). Immunohistochemistry indicated that in A group the p-tyrosine was more positively expressed at the bronchial smooth muscle, bronchial epithelium, smooth muscle of vessel and inflammatory cell, especially at smooth muscle of bronchi and vessel and inflammatory cell than that of C group (P <0.01), there was no difference between B group and C group (P > 0.05).

CONCLUSIONPTK played a key role in inflammation and bronchial remodeling in lung of guinea pigs with bronchial asthma. The Protein tyrosine kinase inhibitor genistein could prevent and inhibit the inflammation and bronchial remodeling in lung of guinea pigs with bronchial asthma.

Objective:To express Tumstatin_(183-230)-TRAIL fusion protein and to observe its biological functions.Methods: SOE-ing PCR was employed to amplify the recombinant sequence of Tumstatin_(183-230)and TNF-related apoptosis-inducing ligand (TRAIL_(114-281)).An expression vector pMAL-Tu-T was constructed by inserting Tu-T sequence into pMAL-c_2;the vector was used to transfect E.coli BL21(DE3)and expression of MBP-Tu-T fusion protein was induced by IPTG.Amylose Resin columns were employed to purify the fusion protein.The biological functions of MBP-Tu-T protein was examined by inhibitory test of endothelial cell proliferation,standard tumor cell cytotoxic assay,in vitro tube formation inhibition,and electron microscopic observation(apoptosis).Results:The expression rate of MBP-Tu-T fusion protein in E.coli was about 20%. Purified recombinant protein obviously inhibited endothelial cell proliferation(IC_(50)12.5?g/ml),induced apoptosis of pancreatic cancer cells,and inhibited tube formation.Conclusion:Constructed MBP-Tu-T fusion protein is bifunctional,which lays a solid foundation for further investigation of antitumor effect of Tumstatin_(183-230)-TRAIL in vivo.

Objective To explore the effects of continuous nursing intervention with regular care on health related behaviors in patients undergoing coronary artery bypass graft (CABG). Methods 80 undergoing CABG patients were recruited to the control group and the study group. All the subjects received regular care.Besides this, patients in the study group received continuous nursing intervention, which include: carrying out education and handing out handbooks before discharging, implementing telephone follow-up after discharging.The health related behaviors, which included 6 parts: nutrition, exercise, stress management, medicine management, complication management and smoking, were measured in the 4th week, 8th week and 12th week after discharging from the hospital. Results Patients in the study group had better health related behaviors than those who received regular care alone, specifically including better nutrition, exercise, medicine management and complication management behaviors. However, the differences of stress management behaviors and smoking between the two groups were non-significant. Conclusions The continuous nursing intervention was a safe and effective intervention style.

OBJECTIVETo observe the changes in motilin (MTL), substance P (SP), vasoactive intestinal peptide (VIP) and somatostatin (SS) in plasma of rats with severe scald injury at early stage and the effect of rheum on their changes.

METHODSEighty-eight Wistar rats were randomly divided into normal control group (NC, n = 8), scald group (S, gavage of distilled water after full-thickness scald, n = 40), therapeutic group (T, gavage of rheum solution after full-thickness scald, n = 40). The blood samples were harvested from inferior vena cava at 6, 12, 24, 48, 72 post scald hours (PSH) to determine the levels of MTL, SS, SP and VIP with radioimmunoassay.

RESULTS(1) The levels of MTL and SP were (198 +/- 28), (61 +/- 10) ng/L, respectively, in NC group. The levels of MTL and SP in S group reached their minimum values [(110 +/- 15), (30 +/- 5) ng/L, respectively] at 6 PSH, then ascended slowly, peaked at 72 PSH but still lower than those in NC group (P < 0.05). The levels of MTL and SP slowly descended in T group, reached normal levels at 48 PSH, and obviously higher than those in NC group at 72 PSH [(232 +/- 32), (73 +/- 11) ng/ L, respectively, P < 0.05], which were higher than those in S group at 6 -72 PSH. (2) The levels of VIP and SS were (35 +/- 6), (30 +/- 5) ng/L, respectively, in NC group. The levels of VIP and SS in S group were (70 +/- 12), (49 +/- 9) ng/L at 6 PSH, which were obviously higher than those in NC group (P < 0.01), then descended slowly, but still higher than normal level at 72 PSH (P < 0.05). The levels of VIP and SS in T group ascended slowly, reached the normal level at 48 PSH, which were lower than those in S group at each time points, and VIP reached peak value at 12 PSH.

CONCLUSIONRheum may regulate secretion and release of gastrointestinal hormones to plasma in rats with severe scald injury at early stage.

To study the proliferation characteristics of PPV in differently infected way and the variance of concentrations in different cells. A strain of porcine parvovirus(PPV) was adapted to PK-15 cells, and a Real-time fluorescent quantitative PCR (FQ-PCR) assay was developed based on the specific region of the NS1 gene of PPV to quantify the PPV. The FQ-PCR was used to measure the viral concentration of virus-infected cells by simultaneous or step by step inoculation and plot one-step growth curves. The proliferation characteristics of PPV strain in different cells lines (HeLa, MDBK, PK-15 ,ST, F81, BHK-21 and Marc-145) was also compared. The results showed the PK-15 cell -adapted strain of PPV produced CPE after 12 passages, and maintained stable CPE at the following 10 messages. The one-step growth curve showed that the virus concentration of simultaneous inoculation was higher than that of the step-by-step inoculation, and the proliferation cycle of step-by-step inoculation was shorter. The proliferation ability of PPV strain in different cells showed that CPE appeared first inPK-15, followed by ST, HeLa and MDBK, and the virus concentration was highest in ST, followed byPK-15, MDBK and HeLa. NO proliferation was observed in F81, BHK-21 and Marc-145 cells. These findings lay a material foundation for the basic researches on PPV and the development of vaccine.
