OBJECTIVEIo compare the difference on the clinical efficacy in treatment of chronic nephritis albuminuria between acupuncture and moxibustion at "Xiasanhuang", DONG's extra points and benazepril hydrochloride so as to provide the effective therapeutic method for the treatment of chronic nephritis albuminuria. Methods One hundred and six cases of nephritis albuminuria were randomized into an acupuncture and moxibustion group and a western medication group, 53 cases in each one. In the acupuncture and moxibustion group, acupuncture and moxibustion were applied to "Xiasanhuang" (Tianhuang fuxue namely "shenguan", "Dihuang", "Renhuang"), once a day, the interval of 2 days once every 10 treatments. In the western medication group, benazepril hydrochloride was prescribed for oral administration, 5 to 10 mg each time, once a day. The treatment of 2 months made, one session in the two groups. After 1 session treatment, the clinical efficacy, red blood cell count (RBC) of urinary sediment, 24 h urine protein quantitation and creatinine clearance rate (Ccr) before and after treatment were observed in the two groups.

RESULTSThe total effective rate was 84. 9% (45/53) in the acupuncture and moxibustion group, superior to 52. 8% (28/53) in the western medication group (P<0. 01). After treatment, RBC of urinary sediment and 24 h urine protein quantitation were reduced as compared with those before treatment (P< 0. 01, P<0. 05), and the results in the acupuncture and moxibustion group were lower than those in the western medication group (P<0. 05, P<0. 01). After treatment, Ccr in the acupuncture and moxibustion group was higher than that before treatment (P<0. 05) and higher than that in the western medication group (P<0. 05). Ccr was not different significantly before and after treatment in the western medication group (P>0. 05).

CONCLUSIONAcupuncture and moxibustion at DONG's extra points (Xiasanhuang) reduce proteinuria and improve kidney, function in patients of chronic nephritis and the efficacy is better than that with benazepril hydrochloride.

AIM: To investigate the relationship between the prevention of probucol on restenosis and vascular remodeling after percutaneous transluminal angioplasty(PTA) in rabbits. METHODS: New Zealand rabbit thoracic aorta atherosclerosis was induced by 3.5F ballon catheter injury following a 4-weeks feeding of high cholesterol diet, and PTA was performed by using 3.5F balloon catheter. Probucol(1g/d) or vitamin E (400 mg/d) was administrated one week before PTA. Two weeks after PTA, the bore and outside diameter (OD) of arteries, the area circumscribing by intimal elastic lamina (IEL), the area circumscribing by extral elastic lamina (EEL), medial area (MA), neointima area/medial area (NEA/MA) were analyzed by computerized digitizer system. Lipids of serum were measured by means of biochemical assay.RESULTS: After two weeks of PTA, the intima proliferation and lumen restenosis were observed obviously. However, with probucol treatment for 3 weeks, the restenosis of aorta was inhibited significantly by increasing bore, outside diameter, and lumen area of rabbits aortas and decreasing NEA, NEA/MA. Furthermore, probucol regulated vascular remodeling by increasing the area circumscribing by IEL [(3.50?0.20)mm 2 vs (1.59?0.23) mm 2, P

Objective To investigate the vasodilatation effects of total flavonoid from polygonum aviculare on rat thoracic aorta and its underlying mechanisms. Methods Total flavonoid from polygonum aviculare was gotten by extracted with 65% alcohol, gathered with polyamide, and eluted with 75% alcohol.The content of flavone was determined with rutoside as standard preparation. Normal rats thoracic aorta in vitro used as sample, BL-420E biological functional experiment system was utilized to record dilatation effect of total flavonoid on PE affecting pre-contracting blood vessel and the relation between dilatation effect of total flavonoid on blood vessel and calcium influx. Results Total flavonoids from polygonum aviculare can diastole contractions of thoracic aorta caused by PE. In calcium-free perfusion, gradually adding CaCl2 induced calcium influx. Clinical data showed dose-effect relation between drug and blood vessel contraction decreased in the total flavonoids from polygonum aviculare incubation rats than normal rats. Besides, total flavonoids from polygonum aviculare can obviously inhibit contraction of blood vascular circle induced by calcium releasing.Conclusion FP exerted a dose-dependent vasodilatation effect on rat isolated aorta rings by inhibiting Ca2+influx via L-type voltage-gated Ca2+ channels and Ca2+ release from sarcoplasmic reticulum, consequently decrease Ca2+ in vascular smooth muscle cells.

Objective To investigate the value of continuous renal replacement therapy (CRRT) coupled with minimally invasive ultrasound-guided percutaneous transhepatic gallbladder drainage (PTGD) for the treatment of severe acute biliary pancreatitis.Methods Hospitalized patients with severe acute biliary pancreatitis were recruited from the intensive care unit (ICU) of the Mfiliated Hospital of Qingdao University from June 2010 to June 2015,and divided into conventional CRRT alone group (n =30) and CRRT + PTGD group (n =30).Comparisons of postoperatively symptoms (time required for abdominal pain relief,time consumed for,gastrointestinal decompression),laboratory findings (WBC,PLT,PCT,CRP,AMS,TBIL,ALT,ALB,Lac) and acute physiology and chronic health evaluation score (APACHE Ⅱ,Balthazar CT,MODS) were carried out between two groups.The occurrence of complications (ARDS,abdominal infection,bile leakage,abdominal hemorrhage,intestinal injury,catheter translocation,catheter dislocation) was observed.The differences in duration of ventilator support,the length of stay in ICU,and fatality rate were compared between the two groups.Results Compared with the conventional CRRT alone group,the postoperative symptoms were significantly relieved,and time required for abdominal pain relief and time consumed for gastrointestinal decompression were evidently shortened in the CRRT + PTGD group (P ＜ 0.05).There were statistically significant differences in laboratory findings (WBC,PLT,PCT,CRP,AMS,TBIL,ALT) between two groups (P ＜ 0.05).The differences in APACHE Ⅱ,Balthazar CT and MODS score between the two groups also presented statistical significance (P ＜ 0.05).The comparisons of the duration of ventilator support [(6.1 ± 1.3) d vs.(9.5 ± 1.4) d] andthe length of stay [(15.7 ± 1.1) dvs.(21.1 ± 2.5) d] between thetwo groups revealed statistical significance (P ＜ 0.05).Conclusions CRRT coupled with PTGD for the treatment of severe acute biliary pancreatitis can effectively eliminate the inflammatory mediators and toxins from patients.On this basis,the coupled therapy with gallbladder puncture and drainage is capable of decompressing the biliary tract,improving liver function,effectively relieving clinical symptoms,minimizing the changes of laboratory findings an,d APACHE Ⅱ score,and thereby optimizing the prognosis of patients.

Objective To establish Ad-hLIF transgenic feeder cells for the expansion of umbilical cord blood CD34+ HSPC in vitro and study the SCID mice model of hematopoietic stem/progenitor cell (HSPC) transplantation. Methods The expression of objective gene in Ad-hLIF transgenic feeder cells was detected by RT-PCR and ELISA. The purity of umbilical cord blood CD34+ HSPC separated by magnetic-activated cell sorting(MACS) was detected by the flow cytometry. After expanded with various combinant of cytokines and transgenic feeder layer cells for 28 d, the quantity of mono-nuclear cell (MNC) and CD34+ cells rate was detected in different time. MNC after expansion stained by CFDA SE was injected to the sublethally irradiated SCID mice. Humanize gene Alu was detected by RT-PCR and fluorescence microscope. Results The green fluorescence was observed in the transgenic cells infected with 50MOI( multiplicity of infection) Ad-hLIF, and the objective gene was confirmed by RT-PCR and ELISA. The purity of umbilical cord blood CD34+ HSPC separated by MACS could reach 95.60% ±2.58%, Ad-hLIF transgenic feeder cells and various cytokines system increased MNC by 356.95±0.87 fold, and maximal expansion of CD34+ cells was observed during 0-14 d of culture, then down-expansion gradually. Four weeks after transplanted in SCID mice, fluorescently-labeled humanize cells still can be observed. The existence of the humanized gene Alu was confirmed by RT-PCR. Conclusion Ad-hLIF transgenic feeder cells can effectively proliferate umbilical cord blood CD34+ HSPC in vitro and delay it differentiate, what's more, it has high transplant efficacy and haematogenesis activity.

Objective:To investigate the effect of alteplase on the expressions of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells after thrombolysis in the rats with acute cerebral infarction and its mechanism,and to provide experimental evidence for its clinical application. Methods: The models of acute thrombosis of middle cerebral artery of the rats were established.Fifty-four SD rats were randomly divided into sham operation group,model group and alteplase group (n= 18).The ultrastructure of brain endothelial cells of the rats was observed under transmission electron microscope.The expression levels of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells of the rats were detected by immunoflurorescence and Western blotting methods.Results:The transmission electron microscope results showed that the brain volume in the ischemic area of the rats in model group was significantly increased and the endothelial cells were swollen,some of the cortical and surrounding brain tissues had obvious boundaries,and the thickness of the basement membrane was uniform and the tightly connected structure was very loose and disappeared;the swelling condition of the capillary endothelial cells in infarcted area of the rats in alteplase group was significantly reduced and the thickness of the basement membrane was improved,and most of the tightly connected structures between the brain capillary endothelial cells and the endothelial cells were loose and the fracture was lost and the structure disappeared.The immunofluorescence results showed that the expressions of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells of the rats in alteplase group were significantly improved compared with model group. The Western blotting results showed the expression levels of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells of the rats in model group were significantly decreased compared with sham operation group (P < 0.01 ); compared with model group, the expression levels of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells of the rats in alteplase group at different time points were increased (P < 0.01 ). Conclusion: Alteplase can improve the structure of brain endothelial cells in the rats with acute cerebral infarction,and the mechanism may be related to decreasing the expressions of Claudin-1 and Claudin-5 proteins in the vascular endothelial cells of the rats induced by alteplase.

This study was performed to explore the differential genes and functions of double-negative T cells in peripheral blood of patients with colorectal cancer.Two colorectal cancer patients and two healthy physical examiners were selected,and peripheral blood double-negative T cells were firstly sorted by flow cytometry,and then sequencing data were obtained using single cell full-length transcriptome(SMART-seq2)sequencing technology to screen differentially expressed genes.The screened differentially expressed genes were subjected to Gene Ontology Enrichment(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis.The STRING database was used to construct the protein interaction network and identify key genes by Cytoscape software;RT-qPCR was used to verify the differential expression genes in DNT cells.Compared with healthy subjects,there were 1 276 peripheral blood double-negative T-cell differential genes in colorectal cancer patients,including 141 up-regulated genes and 1 135 down-regulated genes.GO analysis showed that the differential genes were mainly involved in biological functions such as methylation,metabolic processes and transferase activity;KEGG pathway analysis showed that the differential genes were mainly involved in signaling pathways such as autophagy,P53 signaling pathway and phosphatidylinositol metabolism.The protein interaction network contains 1 154 nodes and 1 022 edges,in addition,10 hub genes were identified:PIK3C3,WIPI1,ATG101,PIK3R4,DDX10,RBM28,SDAD1,ATG16L1,UVRAG,ATG7.RT-qPCR validated 10 differentially expressed genes,of which 7 differentially expressed genes showed trends consistent with sequencing results,and 3 genes showed expression inconsistent with sequencing results.DNT cells may be involved in the development of colorectal cancer through methylation,P53 signaling pathway and autophagy,and at the same time,DNT cells may inhibit the development of colorectal cancer through the regulation of genes.This study provides a theoretical basis for further investigation of the function of DNT cells in malignant tumors.
