Objective To study the influence of different starting time of hyperbaric oxygen(HBO) therapy on severe brain injury patients.Methods 60 cases of acute cerebral infarction patients were divided into 2 groups,namel 48 hours to 7 days group(group A) and 8 days to 15 days group(group B) after injury.Fugl-Meyer assemment and modified Barthel index were employed to assess the patients before and after HBO for 30 days in the 2 groups.Results After 30 days of HBO therapy the Fug-Meyer assemment and modified Barthel index in the A group were better than those of B group,there were significant differences between the 2 groups(P

Objective Through observing the changes of serum creatinine (Scr),blood urea nitrogen (BUN),and Cystatin C (Cys C) to prove whether the treatment of patients of diabetic nephropathy (DN) in V period with Jiawei-qidan-tangshen decoction is really effective.Methods 60 patients of DN in V period were randomly divided into a treatment group and a control group by random number table method,with 30 patients in each group.Glycated hemoglobin (HbA1c),serum creatinine (Scr),blood urea nitrogen (BUN),and Cystatin C (Cys C) were detected before and after the treatment.Results 12 weeks after treatment,Scr,Cys C (19.19±37.06) μmol/L,(1.81 ±0.69)mg/L had significantly declined in the treatment group (P＜0.001),and had no significant change (147.25±62.70)μmol/L,(2.04± 1.20)mg/L in the control group (P＞0.05).Total effective rate of Scr and Cys C was 73.33％ and 83.33％ in the treatment group and 40％ and 53.33％ in the control group respectively,both showing significant difference (P＜0.05).Conclusion It is effective to treat patients of DN in V period with,Jiawei-qidan-tangshen decoction,and have no obvious side effects.

The etiology and pathogenesis of Crohn’s disease(CD)are not fully clear,and genetic susceptibility, immunologic disorder,intestinal barrier dysfunction and intestinal microecology are considered to be involved in the pathogenic mechanism of CD. In recent years,the relationship between intestinal microecology and CD has received much attention. Several studies confirmed that the intestinal microecology in CD patients was different from that in normal person. The change of intestinal microecology was correlated with the occurrence of CD,and modulation of intestinal flora was effective in the treatment of CD. This article reviewed the relationship between intestinal microecology and CD and the therapeutic prospect of intestinal microecology for the treatment of CD.

Objective To explore the effects of combined infusion of Treg cells from recipient rats and imDCs from donor rats prolonging the survival time of rats undergoing allogeneic orthotopic liver transplantation.Methods One hundred cases of rat allogeneic orthotopic liver transplantation were performed by using modified two-cuff method: DA rats served as donors,and Lewis rats as recipients,which were divided into 5 groups: acute rejection group,mDC group,imDC group,Treg group,co-infusion group (imDC-Treg group).2 × 106 imDC,2 × 106 mDC and 1 × 107 Treg cells were respectively injected to Lewis rats in every group via caudal vein before transplantation.Four Lewis rats from each group were randomly sacrificed on the day 3,7 and 10 after transplantation.Liver function (ALT and TBIL) and changes of cytokines (IL-10,IL-2 and TGF-β) were evaluated in peripheral blood.The pathological changes of the liver graft were observed.The DNA fragmentation characteristics of apoptosis in the liver were detected by using TUNEL staining.Survival analysis was performed on remnant rats.Results The liver function in imDC-Treg group had reverted to normal faster than that in the control groups.ELISA revealed that at day 7,the serum levels of IL-10 and TGF-β were higher,and the serum levels of IL-2 were lower in imDC-Treg group.Liver pathology demonstrated that there was only a slight number of mononuclear cell infiltration in hepatic graft afterorthotopic liver transplantation in co-infusion group (imDC-Treg group),which belonged to a nonidentified or slight type of acute rejection,and the liver graft showed regeneration of hepatocytes along with a small number of neutrophile granulocyte infiltration at the day 10.TUNEL staining indicated that the number of apoptotic T cells was much less in control groups than in imDC-Treg groups.The survival time of recipients in Treg-imDC group was 37 days,significantly longer than in irnDC group (23 days) and Treg group (15 days).Conclusion Infusion of imDC from donor rats or Treg from recipient rats alone couldn't induce long-term allograft survival of recipients after allogeneic rat liver transplantation.The co-infusion of Treg and imDC significantly prolonged the survival time of rats subject to allogeneic liver transplantation.

Objective:To investigate the effect of basic fibroblast growth factor(bFGF) on the proliferation of gingiva-derived mesenchymal stem cells(GMSCs) in vitro.Methods:GMSCs were isolated from healthy gingival tissue samples and identified.GMSCs of passage 4 were treated by bFGF at 0,0.5,1,5,10,20 ng/ml respectively for 1-9 d.The proliferation of the cells was evaluated using CCK-8 kit.Results:bFGF at 0.5-20 ng/ml increased GMSCs proliferation.0.5-10 ng/ml of bFGF showed dose and time dependant proliferation promoting effect on GMSCs.Conclusion:bFGF can increase GMSCs proliferation ability in a dose and time dependant manner.

Objective To evaluate the prospective electrocardiograph (ECG)-gated 128-slice spiral CT angiography in the diagnosis of complex congenital heart disease and airway abnormality in children.Methods Eighty children with congenital heart disease received prospective (n =40) or retrospective ECG-gated 128-slice spiral CT angiography (n =40).All of the patients underwent ultrasound cardiogram (UCG) within one week before CTA exmination.The image quality and the effective radiation dose were statistically analyzed using independent samples t test and x2 test.The surgical results were taken as the diagnostic standards,and the preoperative prospective and retrospective CT angiography data were compared with UCG results using x2 test.Results The effective dose of prospective ECG-gated CT angiography[(1.00 ± 0.26)mSv] was reduced by 86％ as compared with the retrospective ECG-gated CT angiography[(7.37 ± 0.52) mSv] (t =69.296,P ＜ 0.01).Image quality was graded 0 in none patients,graded 1 in 2 patients who underwent prospective ECG-gated CT angiography,graded 2 in 8 and 1 patient who received prospective and retrospective ECG-gated CT angiography respectively,and graded 3 in 30 and 39 patients who underwent prospective and retrospective ECG-gated CT angiography,respectively.There was no significant difference in image quality between prospective and retrospective ECG-gated CT angiography (x2 =0.044,P ＞ 0.05).The definitive diagnosis of extracardiac vascular anomalies was made in 98.3％(59/60) of patients by using prospective and retrospective ECG-gated CT angiography,which were significantly superior to UCG results[(76.7％ (46/60),76.7％ (45/59),respectively] (x2 =13.144,12.644,P ＜ 0.01),and there was no significant difference in the definitive diagnosis between prospective and retrospective ECG-gated CT angiography (x2 =0.001,P ＞ 0.05).The definitive diagnosis of the cardiac/large-vessel malformations was made in 100％ of the patients by both prospective and retrospective ECG-gated CT angiography,and there was no significant difference between 128-slice spiral CT angiography results and UCG results [97.2％ (35/36),97.3％ (36/37),respectively] (x2 =1.014,0.001,P ＞0.05).In the cardiac malformations,the definitive diagnosis by prospective and retrospective ECG-gated CT angiography was 88.7 ％ (47/53) and 92.5 ％ (49/53),and there was no significant difference between 128-slice spiral CT angiography results and UCG results [98.1％ (52/53),98.1％ (52/53),respectively](x2 =3.824,1.889,P ＞ 0.05),and no significant difference in the definitive diagnosis was observed between prospective and retrospective ECG-gated CT angiography (x2 =0.442,P ＞ 0.05).In addition,the 128-slice spiral CT angiography detected airway abnormality in 9 cases who underwent prospective or retrospective ECG-gated CT angiography.Conclusion The prospective ECG-gated 128-slice spiral CT angiography exhibits great application value in the preoperative diagnosis of complex congenital heart disease,which helps to develop surgical program and evaluate surgical risks.
