Objective To observe the protective effect of Mongolian medicine Carthamus tinctorius in acute liver injury induced by D-GlaN(D-galactosamine)in rat models. Methods The acute liver injury model was established by intragastric administration D-GlaN in rats. The levels of serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),glutathione(GSH-Px),the content of tumor necrosis factor-α(TNF-α)in liver tissue and the apoptosis of hepatocytes were determined. Results Mongolian medicine safflower can significantly reduce the activity of serum ALT and AST and liver tissue GSH-Px,and the degree of cell apoptosis;however,no obvious change of the TNF-αcontent was observed. Conclusion The Mongolian medicine Carthamus tinctorius has protective effect in D-GlaN-induced acute liver injury rats probably via anti-oxi-dative and anti-apoptotic abilities.

Abnormal elevation and abnormal isoenzyme of non-specific esterase (?-NAE) are intimately associated with the genesis and development of cancer.Anti-GCBAP is a new kind of biological response modifier(BRM) which is separated from gastric cancer cells immunized animal spleen. As determined by clonogenic assay. Anti-GCBAP displayed highly-potent, specific cytotoxicity regarding to target cancer cells. In the present study, we have further investigated the effect of Anti-GCBAP on the ?-NAE isoenzymes in gastric cancer-bearing nude mice. The results demonstrated that in vivo adminstration of Anti-GCBAP can not only inhibit tumor growth in tumor-bearing mice, compared with control(p

Objective To explore the value of biomechanics parameter of rabbit abdominal aortic atheroma using velocity vector imaging(VVI).Methods Ten of 45 male New Zealand rabbits were chosen as normal control group randomly,the rest experimental rabbits were made atheromatous plaque model.The rabbits were examined by two-dimensional ultrasound and VVI respectively.The intima-media thickness(IMT) or thickness of plaques of abdominal aorta 1 cm from right renal artery branch were recorded.Maximum tangential velocity,strain and strain rate of IMT or plaques were measured using VVI.Then the rabbits were killed for pathological and immuno-histochemical examination.Results Based on pathology,the rabbites were divided into 4 groups:control group(group A,n=10),group of pathological endometrial thickening(group B,n=9),group of thick fibrous cap atheromatous plaques (group C,n=15) and group of thin fibrous cap atheromatous plaques (group D,n=11).The difference of plaques thickness and biochemical indicators had no statistically significant between group B and C(P>0.05),both bigger than group A and B (P<0.05).The difference of Vmax,Smax and SRmax had statistically significant each group(P<0.05).With Vmax>0.46×10-2 cm/s,Smax>0.37%,SRmax>1.415×10-2 s-1 to find the vulnerable plaques,the sensitivity were 75.0%,84.4%,84.4% respectively,specificity were 70.8%,91.7%,83.3% respectively.Conclusions VVI can identify plaque biomechanics parameter of different progression periods,which is expected to be a reliable method to find vulnerable plaques earlier in clinic.

Objective To identify the correlation between vitamin D prescription and recurrence in rheumatoid arthritis (RA).Methods A randomized controlled trial study was performed in 170 RA patients who were in remission during the past 2 months.According to the level of vitamin D,170 RA patients were divided into normal vitamin D group (84 patients) and deficiency vitamin D group (86 patients).Deficiency vitamin D group were randomly allocated to receive vitamin D treatment(vitamin D treatment group) or without vitamin D treatment (control group).In the 6-month follow-up period,the recurrence status was observed and compared.Results In the 6-month follow-up period,the recurrence rate of RA in normal vitamin D group was 16.7％(14/84),in vitamin D treatment group was 19.0％(8/42) and in control group was 29.5％(13/44),and there was no significant difference (P ＞ 0.05).In vitamin D treatment group,no hypercalcemia and hyperphosphatemia occured.The age,course of disease and remission time in recurrence patients of three groups were no significant difference (P ＞ 0.05).The level of vitamin D in recurrence patients of vitamin D treatment group was higher than that in recurrence patients of control group:(25.5 ± 8.9) ng/L vs.(20.9 ± 8.6)ng/L,and there was significant difference(P＜ 0.05).Conclusion Vitamin D deficiency is not identified to be a risk factor for RA recurrence.Vitamin D does not reduce the recurrence of RA.

Objective To investigate the association of red cell distribution width (RDW) with outcome in patients with septic shock.Methods A retrospectively study was performed on a total of 156 cases with septic shock who hospitalized in the Affiliated Hospital of North China University of Science and Technology from January 2012 to December 2014.All cases were divided into two groups according to the outcome:survivor group and non-survivor group.The data of general information,combined disease,RDW,acute physiology and chronic health score(APACHE Ⅱ) were collected and compared between the two groups.All cases were divided into three subgroup in regard of RDW,group A was ≤ 14.0％,group B was 14.1％-15.9％,group C was ＞16.0％.Multiple Logistic regression analysis was performed to analyze the related factor of mortality.ROC analysis was used to test the predictive effect of RDW for the outcome of septic shock.Results Sixty-nine cases died in 156,with a mortality rate of 44.2％(69/156).The RDW in non-survivor group was significantly higher than that of survivor group((15.79±2.64) ％ vs.(12.69±3.09) ％,P＜0.001).Mortality rate in each sub-group were 21.5％ (14/65) in group A,49.0％ (25/51) in group B,75.0％ (30/40) in group C,respectively,and the difference among the three groups was statistically significant (x2 =29.396,P ＜ 0.001).Logistic regression analysis showed RDW was independently associated with mortality of septic shock.In reference with group A,the risk of mortality was 3.504 (95％ CI:1.563-7.858,P =0.002) in group B and 10.924 (95％ CI:4.314 -27.661,P＜0.001) in group C.Conclusion Red cell distribution width is a risk factor of mortality in patients with septic shock.

Objective To observe the relationship between clinical medication and the prognosis in elderly community-acquired pneumonia (CAP).Methods A prospective randomized controlled single-blind study in Tianjin Hospital Internal Medicine.A total of 160 elderly patients with CAP were selected from January 2011 and January 2015.According to the computer,patients were randomly divided into treatment group and control group,80 cases in each group.Treatment group adopted routine treatment and moderate amount of glucocorticoids in combination with a low-dose of diuretic,and the control group only received routine treatment.In two groups of patients,we observed the initial treatment effect,change in pulse oxygen saturation,the rate of invasive test,the incidence of adverse reactions,mortality rate,total hospital stay,etc.Results Compared with control group,the initial treatment was better,the improvement rate in SPO2 was increased,and the rate of invasive test was decreased in treatment group 72 hours after treatment (x2 =6.234,3.906 and 7.059,respectively,P=0.013,0.048 and 0.008).After the overall prognosis and outcome analysis,compared with control group,the percentage of patients transferred to the intensive care unit,the mortality rate was decreased (x2=4.783 and 4.737,P=0.029 and 0.030),hospitalization cost was declined,and the total hospital stay was shorted (x2 =-72.087 and-5.127,both P＜0.0001).There was no statistically significant difference in the incidence of adverse reactions such as electrolyte disorder and mental disorder(both P＞0.05).Conclusions Corticosteroids in combination with a low-dose of diuretic for the auxiliary treatment of elderly CAP can reduce the mortality rate,decrease the rate of invasive test,and shorten the duration of hospitalization,with no obvious increase of adverse events,and it help to improve the prognosis of CAP patients.

The concentrations of borneol in the serum and brain tissue of rats were determined by gas chromatography. Using brain tissue as a relatively independent system, PHARMFIT and PCNONLIN softwares are applied for the kinetic analysis of the infracorporal process of borneol in order to find out and compare the pharmacokinetic characteristics of borneol in the brain and serum. The results showed that borneol was absorbed very rapidly in the gastrointestinal tract and readily permeates the blood-brain barrier into brain tissue. There was a higher specific value of borneol concentration in the brain and serum. Moreover, the half life of distribution phase of borneol in the brain was three times higher than that in the serum. But the constants of elimination rate of borneol in the brain and serum decreased simultaneously and parallelly, hence the accumulation of borneol in brain will not be found.

One hundred and fifty eight post-stroke patients in the recovering period were divided into intervention group (78 cases) and control group (80 cases).Patients in intervention group received home rehabilitation service provided by general practitioners (GP) for 6 months,while patients in control group received routine rehabilitation.After 6-months,the scores of self-rated health measurement scale (SRHMS) in intervention group were significantly higher than those of control group (P ＜0.01);the visiting time and frequency,medical costs and time of caregiving were decreased (P ＜ 0.01);and the satisfaction score of the patients in intervention group was 97％.The results show that home rehabilitation service can improve effectiveness of rehabilitation for post-stroke patient in recovering period.
