OBJECTIVETo investigate the mechanism that the formulas for activating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood.

METHODRats were established animal model of acute cerebral infarction by referencing Olivette' method. They were randomly divided into model group, the group of the high, middle, low dose of the formulas for activating blood and resolving stasis. Each group and then wasrandomly divided into subgroups by 1, 3, 7, 14, 28 d. Xuesaitong capsule was formulated into 20, 40, 60 g x L(-1) with normal saline. The rats were given gavage drugs once a day until the experient ended, and the model group was administrated by intragastrical perfusion of normal saline. ELISA was used to detect the expression of SCF in peripheral blood and bone marrow among different groups at different time points. Flow cytometry was used to observe the changes of CD117 in blood and bone marrow.

RESULTThe CD117+ HSC and SCF concentration in peripheral blood and bone marrow of model group were increasing during 1-14 d,there was a peak on the 14th day, then the expression was reducing. CD117+ HSC and SCF concentration rising trend in the group of the high, middle dose of the formulas for activating blood and resolving stasis was preceded model group (P < 0.05).

CONCLUSIONActivating blood and resolving stasis can regulate hemopoietic stem cell to produce new blood, and it is through the regulation of CD117+ HSC number to achieve the purpose.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

Objective:To retrospectively analyze the routine clinical laboratory parameters for hepatocellular carcinoma,in an attempt to search for parameters for diagnosis of hepatocellular carcinoma(HCC).Methods:The pre-operation clinical labo- ratory data,such as tumor makers,and serological biochemical indices,hepatitis B virus(HBV)infection markers,and HBV DNA titers,were collected from 828 patients who were pathologically diagnosed as having HCC;then the correlation between these data with tumor size and the pathological grades of HCC was analyzed.Results:It was found that 97.9% of the 828 pa- tients were infected with HBV and 70.9% of them were accompanied by liver fibrosis.We also found that the tumor size was correlated with albumin(ALB),globulin(GLB),A/G,aspartate aminotransferase(AST),ratio of aspartate to alanine amin- otransferase(AST/ALT),gamma-glutamyl transferase(GGT),alkaline phosphatase(ALP),alpha-L-fucosidase(AFU),al- pha-fetoprotein(AFP)and tumor grades;meanwhile,the pathological grades of tumor was correlated to prealbumin(PALB), GGT and tumor size(all P

Background The aspheric intraocular lenses(IOLs)can reduce ocular spherical aberration to some degree.However,the clinical effect depends more on the IOL proper alignment.It becomes more important to study the IOL position in eye,Objective This study was to analyze the position alteration of IOL after phacoemulsification combined with implantation of one-piece soft IOLs.Methods In this prospective control study,80 eyes of 40 patients with age-related cataract were enrolled.The phacoemulsification with IOL implantation was performed in all the eyes.Decentration and tilt of IOL in the nasal superior,superior temporal,inferior temporal and nasal inferior quadrants(the intersection point of the system optical axis and the IOL maximum cross plane were regarded as the ordinate origin)were measured by rotating Scheimpflug camera(Pentacam Oculus)in 3 months postoperatively under the mydriasis condition.Written informed consent was obtained from each subject prior to this trial.Results In the right eye group,the IOL decentered toward temporal in 26 eyes(65％)and infratemporal in 16 eyes(40％).IOLs tilted temporally in the horizontal plane in 37 eyes(92.5％)and tilted inferiorly in the vertical plane in 34 eyes(85.0％).In the left eye group,IOLs decentered temporally 33 eyes(82.5％)and 20 IOLs (50％)infratemporally,IOLs tilted temporally in the horizontal plane in 37 eye(92.5％)and 36 IOLs(90％)tilted inferiorly in the vertical plane.There was no statistical difference for the intercomparsion of horizontal/vertical decentration in various quadrant in the right eye(F =0.221,0.792,P＞0.05).The obvious elevated horizontal decentration was found in the supertemporal and infratemporal quadrants compared with supernasal quadrant in the left eyes but there was no significant difference in the vertical decentration among 3 quadrants(F=0.576,P＞0.05).Decentrations were positively correlated with the tilt in both horizontal and vertical plane(right eye horizontal plane:r=0.374,P=0.002;right eye vertical plane:r=0.402,P=0.001 ;left eye horizontal plane:r=0.377,P=0.002；left eye vertical plane:r=0.347,P=0.002).Conclusions The one-piece soft IOLs(Adapt AO)decenter toward temporal mostly in 3 months after surgery,especially infratemporally in the eye.And the optical axis of the IOL tilt toward infratemperol mostly in both right and left eyes.The decentration and tilt are consisted in the corresponding direction between the right and left eyes.The position of the IOLs showed mirror symmetry between right and left eyes.The IOLs decentration show the positively correlation to tilt whatever in horizontal and vertical plane.

Objective:To explore influence of health education on quality of life and compliance in community pa‐tients with coronary heart disease (CHD) .Methods :A total of 83 community CHD patients were selected and ran‐domly divided into routine treatment group (n=38 ,received routine treatment of CHD ) and health education group (n=45 ,received CHD health education based on routine treatment ) .Score of Seattle angina questionnaire (SAQ) after intervention ,therapeutic compliance and incidence rate of major adverse cardiovascular events (MACE) with‐in six months were compared between two groups .Results:Compared with routine treatment group after interven‐tion ,there were significant rise in each item score and total score of SAQ [total score ,(54.3 ± 7.2) scores vs .(65.4 ± 7.5) scores] ,P<0.05 all;and therapeutic compliance also significantly rose (good rate ,52.6% vs .77.8% ) in health education group , P< 0.05. After six‐month follow‐up ,total incidence rate of MACE in health education group was significantly lower than that of routine treatment group (8.9% vs .26.3% ) , P< 0.05. Conclusion:Health education can significantly improve quality of life ,compliance and prognosis in community patients with cor‐onary heart disease ,which is worth clinical extending and use .
