Objective This study was performed to find the association of the severity of coronary artery disease with ordinary risk factors for CHD and left ventricle heart function in patients with CHD. Methods Selective coronary angiography were carried on 305 consecutive patients admitted to our hospital from December 2008 to April 2009. The severity of coronary disease was accessed by the Gensini scoring system. These patients were divided into two groups, patients with CHD group (251 cases) and control group (patients without CHD) (54 cases) , to compare the difference of ordinary risk factors for CHD between the two groups. Multiple linear regression analysis was used to analyze the association of the severity of coronary artery disease with ordinary risk factors for CHD. We also used linear correlation analysis to investigate the association of the severity of coronary artery disease with left ventricle ejection fraction in patients with CHD. Results The two groups had statistically difference on age, sex, smoking index, hypertension prevalence rate, serum glucose abnormal prevalence rate, diabetes prevalence rate, and metabolic syndrome prevalence rate( P < 0.05). We found that age (β_1 =0.251, P <0.01), sex (β_2 =0.235, P < 0.01), LDL-C concentration (β_3 = 0.241,P <0.01), duration of diabetes (β_4 =0.226, P <0.01) went into multiple linear regression model. We also found the severity of coronary artery disease had a negative correlation ( r = -0. 362, P <0.01) with left ventricle ejection fraction in patients with CHD. Conclusion When we decide to cany out coronary angiography on susceptible patients, we should consider their age, sex, smoking index, whether had hypertension, serum glucose abnormal, diabetes, metabolic syndrome or not. Age, sex, LDLC concentration, duration of diabetes affect severity of coronary artery stenosis independently. Left ventricle ejection function will decrease as coronary atherosclerosis continues.

Objective To invesgate hepatitis B c antigen(HBeAg)as the carrier to construct mixed hepatitis C virus(HCV)therapeutic vaccine.Methods Fused the pTrc-core gene with two synthetic T-epitope antigen gene of HCV,expressed the plasmids pTrc-core-T1 and pTrc-core-T2, applied sucrose density gradient centrifugation to get the fusion protein HBcAg-T1 and HBcAg-T2, dialysised and concentrated the protein,mixed and immunized them in mice using the protein HBcAg (expressed by pTrc-core)as control.The tumor regression trial in mice was evaluated at appropriate time.After immunized four times,got the blood and spleen of mice.Interleukin(IL)-12 in serum were detected by enzyme-linked immunosorbent assay(ELISA),nonspecific T lymphocytes prolifera- tion response of splenic lymphocytes was respectively examined by thiazolyl blue(MTT)assay.T cell subset of splenic lymphoeytes,IL-5 in serum,IL-4 and interferon(IFN)-?in lymphocyte were evalu- ated by FACS.Results Tumor regression trial showed the experimental group formed only one tumor(diameter=0.1 cm),smaller than the T_1T_2 peptides group(diameter=0.9 cm)and blank group(diameter=1.3 cm).FACS indicated that CD8~+ T cell percentage of spleen cells from HBcAg- T_1T_2 group(20.21?2.01)% was higher than T_1T_2 peptides group(15.33?1.45)% and blank group(5.09?1.66)%,the percentage of IFN-?positive cells in these three groups were(1.58?0.05)%,(0.88?0.02)% and(0.53?0.03)%.The ELISA discovered that the level of IL-12 in the experimental group was the highest.Different from above,the IL-4 and IL-5 were lower in the exper- imental group.The detection of eytotoxic T lymphocyte(CTL)activity showed that the quantity of Hela cells infected by HCV in HBcAg-T1T2 stimulated group was different obviously from T1T2 peptides group. Conclusion The mixed protein HBcAg-T1 and HBcAg-T2 can induce stronger cellular immunity and it is able to serve as a therapeutic vaccines candidate specific for HCV.

?Retinoblastoma is a common eye malignant tumor which has high degree of malignancy.The traditional treatment methods are destructive, and the prognosis is poor. Hypoxia-inducible factor-1αhighly express in retinoblastoma and regulate the development and progression of retinoblastoma ( by influencing the proliferation and differentiation of tumor cells and involving in the generation of vascular mimicry ) . This article reviewed the role of hypoxia inducible factor-1αin the development of retinoblastoma which will initiate a new avenue for the treatment of retinoblastoma.

Objective To investigate the clinical effects and safety of combination of open and laparoscopic surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones. Methods 140 elderly patients with gallbladder stones combined with common bile duct stones from May 2014 to May 2015 were randomly divided into control group (65 patients) with traditional open surgery and observation group (65 pa﹣tients) with combination surgery; then compared the perioperative clinical indicators, the total removal rate of stone, the postoperative analgesic used rate and postoperative complications incidence of the two groups. Results The oper﹣ation time, intraoperative blood loss volume, the exhaust time for first time and hospital staying time of observation group was significantly better than control group (P< 0.05). There was no significant difference in the total removal rate of stone between the two groups (P> 0.05). The postoperative analgesic used rate of observation group was sig﹣nificantly lower than control group (P< 0.05). The postoperative complications incidence of observation group was significantly lower than control group (P< 0.05). Conclusion Compared with traditional open surgery, combination surgery in treatment of elderly patients with gallbladder stones combined with common bile duct stones can efficient﹣ly shorten the operation time, speed up the recovery process, reduce the degree of trauma and postoperative pain and helpful to prevent the postoperative complications.

Objective To investigate the expression and significance of p38 mitogen-activated protein kinase (p38MAPK) in hyperoxia-induced lung injury of new-born rats. Methods Totally 160 rats at the age of 12 h were randomly and equally divided into air control group, hyperoxia-induced lung injury group, hyperoxia-induced lung injury+SB203580 group and hyperoxia-induced lung injury + normal saline group. After the injury was inflicted, SB203580 or normal saline at same volume was given intraperitoneally at 5 mg/kg. After the rats were executed at the time points of 12, 24, 72 h and 1 week after the model establishment, the right upper lungs were resected for histopathology, right below lungs for wet weight/dry weight, and left lungs for detecting the expression of p38MAPK by Western blot analysis. Results Hyperoxia-induced lung injury model were established successfully after 72 h by exposure to hyperoxia. No p38MAPK expression was observed in air control group. In hyperoxia-induced lung injury group p38MAPK was detected from 12 h, reached to the peak at 72 h, and decreased 1 week later, and its expression was significantly higher in this group and normal saline group than in SB203580 group. Conclusion p38MAPK is involved in the process of hyperoxia-induced lung injury, and the injury can be relieved by treatment of SB203580.

Objective To observe the structural abnormalities of the painful shoulder in patients soon after stroke by M RI,and to identify the possible causes of post-stroke shoulder pain (PSSP).Methods Patients with hemiplegia following their first cerebrovascular accident were divided into 2 groups:PSSP group (32 patients) and post-stroke no shoulder pain (PSNSP) group (20 patients).Physical findings of affected shoulder and MRI findings of both affected and unaffected shoulders were evaluated.Results Shoulder subluxation was significantly more frequent in PSSP group than in PSNSP group (53％ vs 15％,P ＜0.05).In PSSP group,the incidence rate of rotator cuff injury,subacromial-subdeltoid bursa effusion,glenohumeral joint effusion,effusion of long head of biceps tendon was higher in affected side than that in unaffected side(63％ vs 13％,53％ vs 13％,75％ vs 31％,41％ vs 13％,respectively).In PSNSP group,the incidence rate of glenohumeral joint effusion was higher in affected side than that in unaffected side (70％ vs 17％).But compared with no pain hemiplegic shoulder,only rotator cuff injury and subacromial-subdeltoid bursa effusion were significantly higher in PSSP patients (63％ vs15％,53％ vs 25％,respectively),and there was significant difference between the two groups (P ＜0.05).Conclusion Rotator cuff injury was found to be a possible cause of PSSP.

BACKGROUND:The rise of tissue engineering has opened up new ways for tissue repair and reconstruction of the urinary tract, and the bladder acellular matrix is a better alternative material for urinary tissue engineering.
OBJECTIVE:To construct the compound of hair fol icle stem cells with heterologous bladder acellular scaffold, and to observe the growth of hair fol icle stem cells on the scaffold.
METHODS:Bladder acellular matrix from New Zealand rabbits were prepared and detected using scanning electron microscopy and Masson staining. Passage 3 hair fol icle stem cells were statical y inoculated into the surface of bladder acellular matrix using secondary sedimentation method. Under inverted microscope, cellgrowth was observed, and cellgrowth curves were drawn. cellgrowth on the scaffold surface was observed through histological detection and scanning electron microscope observation.
RESULTS AND CONCLUSION:Prepared bladder acellular matrix was a white translucent film with fiber mesh structure, and no residual cells were seen. Masson staining results indicated that the bladder acellular matrix had col agen structure, and no obvious residual cells. After culture for 48 hours, hair fol icle stem cells grew wel around the bladder acellular matrix under inverted microscope;1 week later, hair fol icle stem cells extended and adhered to the scaffold surface. These findings indicate that hair fol icle stem cells have a good biocompatibility with the bladder acellular matrix through in vitro culture.
