Objective To investigate the effect of acetylcysteine on the inflammation and oxidative stress in elderly patients with chronic obstructive pulmonary disease(COPD).Methods Sixty patients with COPD were divided into two groups by random mechanical sampling method (30 cases each group).The control group was treated with conventional therapy and the treatment group added acetylcysteine for 8 weeks.The levels of tumor necrosis factor- t (TNF- α ),interleukin-6 (IL-6),interleukin -8 (IL-8),superoxide dismutase (SOD),malondialdehyde (MDA) were monitored and analyzed before and after treatment.Results The levels of SOD,MDA were (51.08 ± 7.80),(75.09 ± 8.03) μ U/L and (7.13 ± 0.89),(4.51 ±0.61 ) μ mol/L before and after treatment in the treatment group,and (52.12 ± 7.31 ),(65.16 ± 8.01 ) μ U/Land (7.11 ± 0.87),(6.21 ± 0.78 ) μ mol/L in the control group.There were significant differences before and after treatment in two groups (P＜0.01 or ＜0.05),and there were significant differences after treatment between two groups (P ＜ 0.05).The levels of IL-6,IL-8 and TNF- α were significant differences before and after treatment in the treatment group [ ( 18.25 ± 7.24) ng/L vs.(29.02 ± 6.70) Ng/L,( 115.28 ± 13.76 ) ng/Lvs.(148.99 ± 16.61) ng/L,(20.43 ±3.92) ng/L vs.(32.32 ± 8.18)ng/L] (P ＜0.05).But there was nosignificant difference before and aftertreatment in the control group [ (25.25 ± 7.55 )ng/L vs.(28.82 ± 7.54)ng/L,( 136.27 ± 12.97) ng/L vs.( 150.21 ± 17.52) ng/L,(28.43 ± 3.92) ng/L vs.(32.56 ± 8.78) ng/L] (P＞0.05),there were significant differences after treatment between two groups (P ＜0.05).Conclusions Acetylcysteine can inhibit inflammation and e hminate free radicals in plasma.Acetylcysteine has beneficial effects on COPD.

Objective:To analyze the monitoring results of high resolution esophageal manometry (HRM) and 24-Hour impedance-pH for the patients with functional heartburn (FH)and non-erosive reflux disease(NERD), and explore the effect of Gastroesophageal junction morphology, transient lower esophageal sphincter relaxation and regurgitation of gastric acid in FH and NERD.Methods: 86 patients with continuous heartburn who were negative under endoscope were divided into FH group(38cases) and NERD group(48cases), and gastrointestinal symptom rating scales (GSRS), the results of HRM and 24h pH/impedance monitoring of the two groups were compared and analyzed.Results: The GSRS of sour regurgitation, abdominal distension, diarrhea and constipation of FH group were significantly higher than that of NERD group, respectively(t=-4.45,t=3.83,t=3.07,t=4.58,P<0.05). The ratio of esophagogastric junction-III(EGJ-III)of FH group was significantly lower than that of NERD group (Z=-3.27,P<0.05). And the ratio of esophageal hiatus hernia of FH group was significantly lower than that of NERD group(x2=16.01,P<0.05). In HRM parameters, the differences of lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure(UESP), distal contractile integral(DCI)and esophagogastric junction- contractile integral (EGJ-CI) between FH group and NERD group were statistically significant(t=6.99,t=-4.51,t=-2.91,t=-3.72;P<0.05), respectively. On the other hand, the times of sour regurgitation in erect position, the ratio of fluid regurgitation, exposed time of erect position and clinostatism, and DeMeester integral of NERD group was statistically significant higher than that of FH group(t=-9.48,t=-13.00,t=-13.56,t=-18.31;P<0.05).Conclusion:There are esophageal dysfunction in a certain degree and obvious regurgitation in both of two groups, and the detections of HRM and 24h-impedance pH contribute to differential diagnosis for NERG. Besides, the symptom of patients with FH may be relative with regurgitation of non-acidic material, especially may be relative with regurgitation of air.

Objective To investigate the regulation on cell cycle related factor such as Cyclins and P21waf/cip1 by inhibiting histone deacetylase(HDAC)with valproic acid sodium(VPA).Methods HepG2 hep-tocellular carcinoma cells.BGC-823 gastric carcinoma cells and MCF-7 breast cancer cells were cultured with O.75-4.00 mmoL/L VPA for 48 h in vivo.and the cell cycle was analyzed by flow cytometry with PI assay.The protein and mRNA expression of Cyclin A,Cyclin D1,Cyclin E and P21waf/cip1 were analyzed by indirect immu-nofluorescence technique and RT-PCR.respectively.Results Compared with control groups,VPA at concen-trations 0.75-4.00 mmol/L exerted a significant inhibiting effect on G1 phase of HepG2,BGC-823 and MCF-7 cells(P<0.001).and the effect was dose dependent.Cyclin A was down-regulated both at mRNA and protein level in HepG2 and BGC-823 cells(P<0.001),but no difference in MCF-7 cells(P>0.05).Cyclin D1 was down-regulated both at mRNA and protein level(P<0.001)and P2lwaf/cip1 was up-regulated both at the mRNA and protein level in the three cell lines(P<0.001);Conversely,protein and mRNA expression of Cyclin E were unchanged upon treatment with VPA(P>0.05).Condusion Acetylization of histone intervened with VPA can regulate Cyclin D1 and P21waf/cip1 expressions obviously.To the expression of Cyclin A,it shows some difference according to the histogenesis and phenotypes of different carcinoma types.But there is not any obvious function on Cyclin E.Down-regulating Cychn D1 and up-regulating P21waf/cip1 may be the common target path-way in the inhibition of cell cycle G1 phase exerted by VPA.

BACKGROUND:Previous studies have shown that continuous administration of 1×107 of bone marrow mesenchymal stem cel s can induce immune tolerance in rats undergoing kidney transplantation, but it is not yet found clinical y that curcumin exerts an on immunomodulatory effect on kidney transplantation.
OBJECTIVE:To investigate the effects of different concentrations of curcumin on bone marrow mesenchymal stem cel s-induced immune tolerance in rats after kidney transplantation.
METHODS:Rat model of kidney transplantation was made, and rat models were randomly divided into four groups:transplantation group with no treatment;bone marrow mesenchymal stem cel s group (cel group) injected with 1×107/kg bone marrow mesenchymal stem cel s via the left iliac vein (before peritoneal suture) and tail vein (from the 2nd day) for 10 days;bone marrow mesenchymal stem cel s+low/high dosage of curcumin groups (low/high dosage curcumin groups) injected intragastrical y with 2 or 10 mg/kg curcumin combined with injection of bone marrow mesenchymal stem cel s for 10 days. Transforming growth factor-β1 protein expression in the kidney tissues was examined by immunohistochemical staining. The concentrations of interleukin-2 and interleukin-6 in serum were detected by ELISA assay.
RESULTS AND CONCLUSION:After kidney transplantation, the protein expression of transforming growth factor-β1 in renal tubular epithelial cel s and renal interstitial cel s as wel as the concentrations of interleukin-2and interleukin-6 in serum were significantly higher in the transplantation group than the other groups (P<0.05). Compared with the cel transplantation group, the protein expression of transforming growth factor-β1 as wel as the concentrations of interleukin-2 and interleukin-6 reduced significantly in the low/high dosage curcumin groups (P<0.05). These findings indicate that simultaneous administration of curcumin and bone marrow mesenchymal stem cel s can effectively inhibit immune rejection reaction and improve renal function in rats after kidney transplantation.

BACKGROUND: Various types of collagen affect differentiation and expression of chondrocytes in the process of tissue engineered culture for cartilage. The reliability of cartilage tissue engineering is determined by resource, structure and property of collagen.OBJECTIVE: To characterizing the structure of collagen type Ⅰ,Ⅱ and Ⅲ, to clarify the structural characteristics of collagen for cartilage tissue repairing and provide guidance for choosing cartilage tissue engineering scaffolds. METHODS: The type Ⅰ and Ⅲ collagen was obtained from neonatal calf skins, and type Ⅱ collagen was obtained from porcine articular cartilage. The differences of structures of collagen type Ⅰ,Ⅱ and Ⅲ were analyzed and compared by FTIR, DSC, SDS-PAGE and picrosirius-red staining.RESULTS AND CONCLUSION: The neonatal calf collagen type Ⅰ,Ⅱ and porcine collagen type Ⅱ had the similar functional group. The thermal denaturation temperature of the three type collagen was 104.2 ℃, 99.7 ℃ and 92.5 ℃. SDS-PAGE analysis showed the collagen type Ⅲ percentage in collagen type Ⅰ was (11.29±0.91)%. Picrosirius-red staining exhibited that the collagen type Ⅰ was comprised red and orange raw fibers, with strongly birefringent. Collagen type Ⅲ was lax and thin, greenish fibers, but collagen type Ⅱ was red, loosely cancellated fibers. The functional groups and important characteristics of the three of collagen are similar. However, there are some differences in advanced structure. To analyze the relationships of collagen type Ⅰ,Ⅱ and Ⅲ is important to choose and prepare scaffolds for cartilage tissue engineering.
