Objective To explore the clinical efficacy of scalp acupuncture on allomnesia post stroke. Methods 60 stroke patients with allomnesia were randomly divided into observation group (n=30) and control group (n=30). The control group accepted routine rehabilitation training for 4 weeks, while the observation group accepted scalp acupuncture in addition. They were evaluated with Rivermead Behavioral Memory Test (RBMT-II) before and after treatment. Results RBMT-Ⅱ scores improved in both groups after treatment (P<0.05), and improved more in the observation group than in the control group (P<0.05). Conclusion Scalp acupuncture may improve the effects of rehabilitation on the memory dysfunction in patients with stroke.

Objective To investigate the characteristic of 13C-methacetin breath test (13C-MBT) as a tool to monitor the hepatic function of patients with hepatic carcinoma by comparing with Child-Pugh classification and general liver function. Methods Thirty-nine patients with primary liver cancer, 16 patients with hepatic metastasis and 14 healthy volunteers serving as controls were included in this study. According to Child-Pugh classification, the primary liver cancer patients were divided into A, B and C subgroups. All subjects received 13C-MBT and routine liver function tests after an overnight fast. The three major parameters of 13C-MBT i.e. maximum excretion rate before 40 min (Mwnax40), 13CO2 cumulative excretion of 40 min(CUM40) and that of 120 min(CUM120) were recorded and the two metabolism curves (DOB curve, MV curve) were made. Results (1) In the control, hepatic metastasis and primary liver cancer groups, both the DOB curve and MV curve were similar in shape; the peak time occurred at about 20 min after administration and then the curves lowered progressively. There were significant differences between the primary liver cancer group and the other two groups, but it was not statistically different between the hepatic metastasis group and the controls. The shape was obviously distinct in the groups A, B and C of primary liver cancer. The group A had a single sharp peak curve, group B a relatively flat peak curve with a lower level for a long time after the ascending phase and group C no clear excretion peak or even a negative curve. (2) As to the three parameters of 13C-MBT, there were statistical difference between the primary liver cancer group and the other two groups(P <0. 05). Between hepatic metastasis group and controls,there was statistical difference about CUM120 (P <0. 05), but no statistical difference about Mvmax40 and CUM40. While in the three groups with primary liver cancer groups, there was statistical difference between group A and B in Mvmax40 and CUM40 ( P < 0. 05 ), but no statistical difference between group B and C. As to CUM120, there was statistical difference only between group A and C. (3) Comparing the three parameters of 13C-MBT with routine liver function tests, there was negative correlation with TBA, positive correlation with Alb, PA, ChE and no correlation with ALT, AST, TBil, γ-GT, ALP and PT. (4) There was a good consistency between 13C-MBT and Child-Pugh classification in the evaluation of liver function of patients with liver cancer ( Kappa = 0. 647, P < 0. 05 ). Conclusion The value of the three parameters of 13C-MBT is decreased with severity of the liver disease and 13C-MBT may be used to evaluate the reserved hepatic function in patients with primary liver cancer with a diagnostic value equivalent to Child-Pugh classification. The study further confirms that 13C-MBT has correlation with TBA,AIb, PA and ChE.

Objective To investigate the effects of pentoxifylline on the cell proliferation of, collagen synthesis and TGF-β1 expression by human fibroblasts derived from keloid. Methods Skin samples were obtained from the lesions of 3 patients with keloid and normal skin of 3 human controls followed by primary culture of fibroblasts. Fibroblasts of 5th to 8th generation were cultured with pentoxifylline of 0.1 to 3 g/L for various durations. Then, MTT assay was performed to detect the cell proliferation of fibroblasts, double antibody sandwich-enzyme linked immunosorbent assay (ELISA) to measure the expression of TGF-β1, and reversetranscription PCR to examine the mRNA expressions of procollagen Ⅰ and Ⅲ in these fibroblasts. Results The pentoxifylline of 0.1 to 2 g/L markedly inhibited the proliferation of fibroblasts derived from keloid lesions and normal skin, in a dose- and time-dependent manner, with the strongest effect observed in fibroblasts treated with pentoxifylline of 2 g/L. A significant reduction was induced in the TGF-β1 mRNA expression in keloidand normal skin-derived fibroblasts by pentoxifylline of 0.5 to 2 g/L (all P < 0.01), and in the mRNA expression of procollagen Ⅰ and Ⅲ by pentoxifylline of 1 and 2 g/L (P < 0.05 or 0.01). Concretely, the relative mRNA expression level of procollagen Ⅰ and Ⅲwas 0.873 ± 0.077, 0.571 ± 0.050 respectively in keloid fibroblasts respectively, and 0.473 ± 0.035, 0.370 ± 0.045 in the control fibroblasts, after treated with pentoxifylline of 1 g/L, 0.750 ± 0.036 and 0.433 ± 0.045 respectively in keloid-derived fibroblasts, 0.390 ± 0.030 and 0.250 ±0.123 respectively in the control fibroblasts, after treated with pentoxifylline of 2 g/L, significantly lower than that in the keloid-derived (1.216 ± 0.061 and 0.953 ± 0.060) and control (0.836 ± 0.080 and 0.776 ± 0.041) fibroblasts without treatment. Conclusion Pentoxifylline shows an evident suppressive effect on the cell proliferation of, as well as the expression of TGF-β1 and procollagen Ⅰ and Ⅲ in fibroblasts derived from keloid lesions and normal skin.

BACKGROUND:In recent years,pentoxifyIline has been found to have a wide range of anti-fibrosis capacity However,there are few studies explore the suppress effect of pentoxifyIline on fibroblasts in human keloid.and the maximum inhibitory concentration remains poorly understood.OBJECTIVE:To study the effect of pentoxifyIline on proliferation activity of human keloid fibroblasts and to select the maximum inhibitory concentrationMETHODS:Human keloid fibroblasts were used as original cells,passaged till the 5~(th) to the 8~(th) generations.and then divided into the experimental and control groups.PentoxifyIline with concentrations of 0.1,0.25,0.5,1.0,2.0 and 3.0 g/L were added to the experimental group.The effects of different concentrations of pentoxifylline on proliferation of keloid fibroblasts were detected by MTT chromometry.RESULT AND CONCLUSION:Compared with the control group,the inhibitory effect of pentoxifylline on the proliferation of keloid fibroblasts was more evident in the experimental group(P＜0.05)The inhibition rates of pentoxifylline on proliferation of keloid fibroblasts showed apparently time-and dose-effect relationships within the concentration of 0.1-2.0 g/L.which presented a greatest level at 96 hours after culture.The maximum inhibitory rate was 53 37%,and the concentration was 2.0 g/L in the experimental group.Consequently,pentoxifyIline plays a notable inhibitory role in the proliferation of human keloid fibroblasts with concentration of 2.0 g/L at 96 hours after culture.

Idiopathic pulmonary fibrosis(IPF), with unknown pathogeny, is an interstitial lung disease.The pathological features are diffuse epithelial-cell lesion, fibroblast proliferation, myofibroblast differentiation and excessive extracellular matrix deposition.CXCR4 is the predominant chemokine receptor on fibrocytes;CXCL12 is the only ligand of CXCR4.A large number of studies have shown that CXCL12/CXCR4 biological axis plays an important role in the pathogenesis of idiopathic pulmonary fibrosis.Under the regulation of hypoxia, HIF-1α and PI3K-Akt-mTOR path, CXCL12/CXCR4 biological axis promotes lung fibroblast proliferation, myofibroblast differentiation and extracellular matrix deposition, resulting in development and progression of IPF.

We analyzed the pathogenic characteristics of Salmonella strains isolated from diarrhea patients in Wuxi City,Jiangsu Province,China and compared the differences among pulse field gel electrophoresis (PFGE) patterns of main serotype strains,so as to provid scientific basis for disease control.After biochemical identification of the Salmonella strains isolated from infectious diarrhea patients in Wuxi in 2015,drug susceptibility test,serotyping and PFGE were applied to analyze these strains.Results showed that a total of 32 Salmonella strains were detected from 756 diarrhea specimens with a positive rate of 4.23 ％.The infection occurred more frequently between May and October and adults aged more than 60 years old affected mostly.There was no significant difference between genders in infected population.The drug susceptibility test indicated that the antibiotic resistance rate of these Salmonella strains to ampicillin (56.25 ％) was the highest,and to ciprofloxacin(6.25 ％)and Ceftazidime (6.25％) were the lowest.The 32 Salmonella strains belonged to 11 serotypes,and S.enteritidis(31.25％)and S.typhimurium(21.88％) were the predominant serotypes.PFGE showed that the pattern similarity of all S.enteritidis was more than 85 ％;PFGE patterns of S.typhimurium were different.In conclusion,the infection of Salmonella from diarrhea patients in Wuxi City had obvious season and age specific distribution,and the most prevalent serotype of Salmonella was the S.enteritidis.It is necessary to strengthen the surveillance of Salmonella concurrently in food and environment.
