This study was aimed to observe four kinds of kidney-tonification medicine, which were Epimedium, pso-ralen, Ligustrum lucidum, Polygonum with the active ingredient of icariin, psoralen, oleanolic acid, stilbene glucoside and their orthogonal compatibility. There were two kinds of non-kidney tonification medicine, which were Chuanx-iong and astragalus with the active ingredient of TMP and astragaloside. The observation was made on the regulatory role of rat bone marrow stem cells (BMSCs). A total of 65 SD rats were randomly divided into the normal control group, positive transformed control group, kidney-tonification compatibility group (including Group 1, Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, and Group 9), non-kidney tonification medicine control group (in-cluding TMP group and astragaloside group). Intragastric administration of medication was given to the kidney-tonifi-cation compatibility group and the non-kidney tonification medicine control group, once a day for 3 consecutive days. Intragastric administration of equal amount of normal saline was given to the normal control group and the posi-tive transformed control group. On the third day of intragastric administration, rats in each group were sacrificed. Serum containing medication was used in the culture of BMSCs for 6, 12, or 18 days. ELISA method was used to quantitatively detect the expression activity and content of BMP2 on the 6th, 12th, or 18th day, in order to evaluate the degree of bone cell differentiation degree. Real-time quantitative PCR method was used for detection of expression of Bmp2, Smad1, Smad4 mRNA in serum containing medication in the culture of BMSCs on the 18th day. The results showed that the kidney-tonification compatibility can improve the expression activity and content of BMP2 culture in vitro, with the peak on the 12th day. The kidney-tonification compatibility groups can upregulate expressions of Bmp2, Smad1, Smad4 mRNA. It was concluded that the active ingredient compatibility of kidney-tonification medicine can promote BMSCs. Its mechanism may be related to the upregulation of expression of Bmp2, Smad1, Smad4 mRNA, and the activity and content of Bmp2.

Objective:To investigate the effects of enteral immunonutrition on the intestinal barrier function and immune function in patients with severe pneumonia.Methods:Ninety patients with severe pneumonia were randomly divided into experimental group (n =45) and control group (n =45).All patients were received conventional therapy.In addition,patients in experimental group were given enteral immunonutrition,while patients in control group were given regular enteral nutrition.The changes of general conditions,intestinal barrier function index and immune function index were determined before treatment,on day 5 and 10 after treatment.The time of invasive mechanical ventilation,APACHE Ⅱ score and clinical effects of two groups were determined on day 10 after treatment.Results:Compared with those before treatment,in both groups,body temperature,respiration,heart rate,white blood cell count were all significantly decreased on day 5 and 10 after treatment (P ＜ 0.05).The above parameters were significantly lower in experimental group than control group on day 10 after treatment (P ＜ 0.05).The levels of serum ET,DAO were significantly decreased on day 5 and 10 after treatment in two groups compared with those before treatment (P ＜ 0.05),and these parameters were significantly lower in experimental group than control group(P ＜0.05).The number of CD3 and CD4 positive cell and the ratio of CD4 +/CD8 + were significantly increased on day 5 and 10 after treatment in two groups when compared with those before treatment (P ＜ 0.05),and these parameters were higher in experimental group than those in control group(P ＜ 0.05).The time of invasive mechanical ventilation,APACHE Ⅱ score were lower in experimental group than those in control group on day 10 after treatment (P ＜ 0.05).The rate of clinical response were higher in the experimental group than that in the control group on day 10 after treatment (P ＜ 0.05).Conclusion:Enteral immunonutrition is more effective in protecting the intestinal barrier function,improving the immune status,enhancing the immunity,reducing the time of invasive mechanical ventilation,and achieving the clinical effects of patients with severe pneumonia.

ObjectiveTo investigate the effects of protein phosphatase 2A (PP2A) inhibitors on the viability of pancreatic cancer cell line PANC-1 and its mechanism.MethodsPANC-1 cells were treated with PP2A inhibitors Cantharidin or Okadiac acid.The activity degree of NF-κB pathway was tested by Western blot.NF-κB pathway was blocked from all sectors by PP2Acα plamid transfection,NF-κB inhibition of protein kinase α (IKKα) and NF-κB inhibitor α (IκBα) dominant negative mutant and p65 interfering plasmid.Cell viability was determined by MTT.ResultsPP2A inhibitors could induce phosphorylation of IKKα,further phosphorylation of IκBα and degradation and followed by the release of p65 into nucleus.When PP2Acα,IKKα dominant negative mutant and IκBα dominant negative mutant were overexpressed,or p65 was interfered,the inhibition rate of Cantharidin on cell viability decreased (31.85±13.37) ％,(23.48±8.98)％,(22.63±5.81)％ and (20.88±3.24)％respectively,and the inhibition rate of Okadiac acid on cell viability decreased (40.17 ± 11.65)％,(27.34±14.28)％,(24.85±3.39)％ and (27.08±3.81)％ respectively.ConclusionsPP2Ainhibitors play a role in preventing pancreatic cancer through PP2Acα/IKKα/IκBα/p65 pathway.

Background Oxidative damage plays an important role in pathogenesis of age-related macular degeneration( AMD ),and its mechanism is the destroy of blood-retinal barrier.Müller cells is a primary component to stabilize the inner barrier of the blood-retina.Researches showed that epidermal growth factor(EGF) can promote the proliferation and migration of animal Müller cells,but less study was found in the effect of EGF on human Müller cells. Objective The present study was to investigate the effects of EGF on the proliferation and migration of human Müller cells and its molecular mechanism. Methods Human Müller cell line MIO-M1 cells were cultured and incubated,and cultured cells were identified using glial fibrillory acidic protein (GFAP),factor Ⅷ,α-smooth muscle actin( α-SMA ),keratin and S-100.Different concentrations of EGF( 0,1,10,30,100 mg/L)was added in freeserum DMEM,and the positive rate of the cells was calculated using 5-bromo-2-deoxyuridine(BrdU) method.The cells were divided into EGF group,H2 O2 group,EGF + H2 O2 group,glucose oxidase ( GO ) group,GO + EGF group,EGF + LY294002+H2O2 group according to the different intervention,and the effects of LY294002 on the proliferation of Müller cells (A590 )were detected by colorimetric assay for cellular growth and survival( MTT assay).The scratch test of Müller cells was used to assess the influence of EGF(0,1,10,30,100 mg/L)on H2 O2-induced damage of human Müller cell.Western blot was used to detect the cell proliferation under the protection of EGF on co-cultured cells using LY294002 and H2O2 and the activation of Akt signal pathways. Results The proliferative rates of the cells were 28.0％,32.9％,39.0％ in 10,30,100 mg/L EGF groups respectively and obviously higher than those in 0,1 mg/L EGF groups (24.5 ％,26.2 ％ ).Under the H2O2 culture,GO culture,respectively,the A570 value of the Müller cell in high concentrations of EGF groups was significantly increased in comparison with lower concentrations EGF groups with the statistical significance among the groups( F=23.582,P=0.000).Compared with EGF+H2O2 group,the A570value of the Müller cells was lowed in EGF+LY294002+H2O2 group.The maximum migration rate of Müller cells was found in 10 mg/L EGF group.Western blot revealed that the presence of H2O2 reinforced the expression of Akt in Müller cells,however,pretreatment with 100 mg/L EGF antagonized the harmful effect of H2O2 on Müller cells.Meanwhile,pretreatment with EGF and LY294002 reduced the expression of Akt in Müller cells. Conclusions EGF can induce the proliferation and migration of human Müller cells with the strongest effect in 10 mg/L.100 mg/L exogenous EGF has a stronger protection to the Müiller cells against H2O2-induced cell damage by activating the PI3KAkt cell survival pathway.

Objective To investigate the apoptosis induction effect of Cantharidin on pancreatic cancer cell line PANC1 and CFPAC-1 and possible mechanism. Methods PANC1 and CFPAC-1 was treated with Cantharidin. Cell growth was determined by MTT. Apoptosis was measured by flow cytometry. Caspase activity was measured by using enzyme chemical method. Apoptosis-related gene expressions were determined by using RT-PCR and Western blotting. Results Cantharidin significantly inhibited the growth of pancreatic cancer cells PANC1, CFPAC-1 and induced apoptosis in a dose-dependent manner. Seventy-two hours after 10 μmol/L Cantharidin treatment, the inhibitory rates of PANC1, CFPAC-1 were (52.95 ± 6.34)％ and (71.21 ±6.30)％. Twenty-four hours after treatment, the early and later period apoptotic cell of PANC1 was increased from 7.35％ to 24.89％, from 6.36％ to 17.73％. The early and later period apoptotic cell of CFPAC was increased from 6.39％ to 24.70％, from 9.21％ to 12.58％ (P＜0.01). Activity of caspase 8 and caspase 9 in PANC1 cells was (155.8 + 11.5)％ and (194.6 ± 14.7)％ when compared with that of control group. Activity of caspase 8 and caspase 9 in CFPAC- 1 was ( 182.5 ± 24.3 ) ％ and ( 215.8 ± 12.2) ％when compared with that of control group ( P ＜ 0. 01 ). The expression of pro-apoptotic genes, TNF-α,TRAILR1, TRAILR2, Bad, Bak and Bid was elevated, the expression of anti-apoptotic Bcl-2 gene was decreased. Conclusions Cantharidin can induce apoptosis in pancreatic cancer cell lines by activating caspase,up-regulating the expression of pro-apoptotic genes and down-regulating the expression of anti-apoptotic genes.

Objective To assess the efficacy of two antibiotic prophylactic regimens in a prospective randomized trial in 1 year for patients undergoing insertion of catheters,and to provide the evidence for uniform consensus existing on the timing,route,and choice of antibiotic.Methods During a period of 12 months,78 patients,who consecutively entered the peritoneal dialysis programme,[45 women and 33 men,mean age (48.2?15.7)years] were included.The prophylactic regimens were a single dose of ceftriaxone (1.0 g) given intravenously 30 minutes before surgery (Group A) and given cefazolin (0.25 g/L) i.p.in the each dialysis bag for 3 days postoperatively (Group B).All operations were performed in one room.The wound was observed every day,and body temperature,Count of white blood corpuscle and type,dialysate were examined every day. Results In Group A and B,none of the patients showed peritonitis or wound infection during the post-operative period (within 10 days).One of 39 patients(2.5%) in the group A,and 2 of 39 patients (5.1%) in the group B had exit site infection (P＞0.05).Conclusions There is no significant difference in the incidence of peritonitis and wound infection between two groups. Prophylactic preoperative single-dose antibiotics intravenously do as well as antibiotics given intraperitoneally for peritoneal dialysis catheter insertion,but is much more convenient.

OBJECTIVETo investigate the application of forward and reversal flow axial island flap in the orbital skin defects.

METHODSAccording to the distribution of superficial temporal artery as well as the anastomoses with the branches of supraorbital artery and supratrochlear artery, etc, the frontal, scalp, preauricular and postauricular island flaps were designed. The flaps were displaced through subcutaneous tunnel to cover all kinds of orbital skin defects.

RESULTS13 cases of forward flow flap and 9 of reversal flow flap out of 22 cases in all were observed. One postauricular reversal flow axial island flap showed the obstruction of venous refluence in early postoperative stage, however, after active treatment, mere the distal epidermal necrosis was revealed. There were six re-operations on the postoperative flap hypertrophy. The others were in good shape and functional state.

CONCLUSIONSThe superficial temporal artery is one of most vital blood supply in the upper face. It has wide anastomoses with the supraorbital artery and supratrochlear artery. As the colors and the nature of the frontal, preauricular and post auricular skin are close to orbital skin, the application of forward and reversal flow axial island flap based on the superficial temporal artery can be used in the reconstruction of all kinds of orbital skin defects.
