OBJECTIVE:To investigate the effects of Shuxuetong injection on related indexes of patients with acute myocardial infarction (AMI).METHODS:The data of 156 AMI patients were analyzed retrospectively,and then divided into control group (65 cases) and observation group (91 cases) according to therapy plan.Control group received routine treatment.Observation group was additionally given Shuxuetong injection 6 mL added into 5％ Glucose injection 250 mL intravenously,once a day,on the basis of control group.Both groups were given treatment for 5 d.The incidence of vascular recanalization,recanalization time,the incidence of reocclusion as well as LVEF,APTT,PT,FIB,the occurrence of adverse cardiovascular events before and after treatment as well as the occurrence of ADR were observed in 2 groups.RESULTS:The incidence of reocclusion and adverse cardiovascular events in observation group was significantly lower than control group,with statistical significance (P＜0.05).There was no statistical significance in the incidence of vascular recanalization,recanalization time or the incidence of ADR between 2 groups (P＞0.05).After treatment,the levels of LVEF,APTT and PT in 2 groups were significantly higher than before treatment,and the observation group was significantly higher than the control group.The levels of FIB in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statistical significance (P＜0.05).CONCLUSIONS:Based on routine treatment,Shuxuetong injection can reduce the incidence of reocclusion,improve cardiac function and reduce the incidence of adverse cardiovascular events without increasing the occurrence of ADR.

Objective To develop the method for determining the concert of Ferulic acid. Method The Ferulic acid in Fuke Shiwei Jiaonang capsule was determinined by HPLC. The analytical column was Hanbon Lichrospher (250 mm?4.6 mm?5 ?m) and mobile phase was Acetonitrile-0.085% phosphate acid(17∶83). Ferulic acid was detected at 230 nm. Results In the scope of 0.0204～0.102 ?g, the contents of Ferulic acid had good liner relationship with their peak area (r =0.9999, n =5). The average recovery rate was 98.32%, RSD was 1.64% (n =5). Conclusion The method was rapid, simple and precise.

Objective To analyze the clinical factors predicting long-term survival after curative resection of pancreatic head carcinoma. Methods The clinical data of 58 patients with ductal adenocarcinoma of pancreatic head who underwent curative resection of carcinoma of pancreatic head from 1996 to 2004 were collected and were analyzed by SPSS 10.0 with Cox Proportional Hazards Model. Results 58 patients, including 30 male and 28 female patients, were involved in this study. Pancreaticoduodenectomy were performed in 14 cases and extended resections were performed in 44 cases. The overall 1, 3, 5 year survival rates was 46.6%, 29.3% and 8.6%, respeclively. The 1,3, 5 year survival rates of pancreatoduodenectomy with extended regional lymphadenectomy was 43.1%, 22.7% and 6.8%, respectively. UICC staging, peri-pancreatic nerve invasion and blood infusion had significant effects on the prognosis after curative resection. Conclusions The long-term prognosis after curative resection of pancreatoduodenectomy was still dismal. Much importance should be paid to early diagnosis and comprehensive management for pancreatic head cancer.

OBJECTIVETo study the use about balloon dilatation before incision for the patients with ureteric stricture.

METHODSSixteen patients with ureteric stricture were included in our study. The cases were reviewed retrospectively with regards to the etiological factor, the site of stricture, symptom and diagnosis. Six patients with ureteric stricture were dilated with balloon before incision using Ho YAG laser. Ten patients with ureteric stricture were dilated with rigid ureteroscope before incision using Ho YAG laser. The double "J" stent was kept for 4-6 weeks after operation. All the patients were followed up by ultrasound, BUN and creatinine. Complete success is defined as symptomatic improvement, resolution of hydronephrosis and absence of ureteric stricture 3 months after removal of the double "J" stent. If the hydronephrosis and ureteric stricture did not deteriorate, and symptom improved after stent removal, it was considered as improvement. Failure is defined as deterioration of hydronephrosis and symptoms upon removal of double "J" stent.

RESULTSThe length of stenosis was from 0.8 to 1.4 cm. Three patients failed to improve after initial dilatation with rigid ureteroscope, but were later successfully dilated using balloon. All the patients who were treated using balloon dilatation were successful. The operative time of balloon dilatation was shorter than that of dilatation by rigid ureteroscope (P < 0.05). However, the cost of balloon dilatation was higher (P < 0.05). The period of follow-up was 3-28 months. None of the patients had any complications. There were 2 cases of recurrent stricture in patients who underwent ureteroscopic dilatation.

CONCLUSIONSDespite a higher cost, balloon dilatation followed by laser incision for ureteric stricture is safe and effective. This technique may be used for selected patients.

To construct a new high effective genetic engineering strain which can express active PAL enzyme in Lactococcus lactis (L.L), and acquire better effect on curing hyperphenylalaninemia rats, Firstly translational fusion vector and transcriptional fusion vector were constructed in E. coli MC1061, and then PAL cDNA was transformed into L.L. Two kinds of high effect strain were compared with their enzyme activity and animal experiment was carried out. The results showed: (1) Two kinds of engineering L.L. were obtained and translational fusion strain has higher level enzyme activity. (2) The amount of transcinnamic aicd reach peak when induced for 6 hours. (3) The blood phe level of the treated rats was significantly reduced compared with non-treated rats when receiving fresh p(NZ8048-PAL)1/NZ9000. The engineering L.L(translational fusion strain) can significantly reduce the blood phe level of the hyperphenylalaninemia rats, which has more superiority than pMG36e-PAL/L. L.

OBJECTIVETo investigate the frequency of p16 and p15 gene methylation in multiple myeloma (MM), and its relationship with bone marrow cell apoptosis and clinical outcome.

METHODSTwenty-two patients with MM were studied to detect p16 and p15 gene methylation. Methylation-specific polymerase chain reaction (MSP) was used to detect gene methylation, and terminal transferase-mediated dUTP nick end-labeling (TUNEL) was used to detect cell apoptosis.

RESULTSp16 and/or p15 gene methylatoin was detected in 10 of 22 patients (45.4%). There were 3 patients with p16 gene methylation, 9 patients with p15 gene methylation, and 2 patients with both genes methylation. The incidence of methylation of p15 gene was higher than that of p16 gene (P < 0.05). The patients with p16 and/or p15 gene methylation had a delayed cell apoptosis, poor response to chemotherapy, and a short over-all survival (OS).

CONCLUSIONThe methylation of p16 and/or p15 gene plays a key role in MM apoptosis pathogenesis. The patients with both p16 and p15 gene methylation had a poor prognosis.

OBJECTIVETo evaluate the safety and efficacy of endovascular therapy for renal artery stenosis.

METHODSPercutaneous transluminal renal angioplasty with stent (PTRAS) was performed on 33 consecutive patients with severe renal artery stenosis who suffered from poorly controlled hypertension or renal dysfunction. They were subsequently underwent 7 to 49 months clinical follow up for the effect of the procedure on renal function, blood pressure control, mortality.

RESULTSAngiographic success was obtained in 32 (97.0%) of the 33 patients. The mortality was 18.2%. After PTRAS, two (6.1%) died of myocardial infarction within 4 months. Four (12.1%) patients with preoperative serum creatinine (Scr) > or = 177 micromol/L died of uraemia within 17 approximately 28 months. Twelve and twenty-four months after the procedure, systolic and diastolic blood pressure of 26 (78.8%) cases with preoperative Scr < 177 micromol/L significantly decreased (P < 0.05), with less antihypertensive medications taken and satisfactory renal function.

CONCLUSIONFor patients without serious cardiorenal disease, PTRAS has a beneficial effect on blood pressure and renal function. For patients with serious cardiorenal disease or preoperative Scr > or = 177 micromol/L, the mortality is higher. PTRAS should be performed prudently. The preservation of renal function may be enhance by using renal protection device.

OBJECTIVETo investigate the effect of endovascular therapy and artery bypass for subclavian artery occlusion disease and to explore a suitable therapeutic procedure.

METHODSThirty-nine patients with subclavian artery occlusive disease received endovascular therapy or arterial bypass from June 1997 to May 2004. Twenty-seven endovascular stenting were performed on 26 patients through the femoral artery (n = 14) or combined brachial artery (n = 12). Retrograde endovascular balloon angioplasty and stent placement were performed on 12 patients. Eight subclavian arteries were punctured with ultrasound localization. On account of unsuccessful stenting, 13 cases received arterial bypass. In addition, endovascular stenting were performed on 9 cases with carotid or vertebrarterial stenoses.

RESULTSThe blood pressure difference was less than 10 mm Hg between the treated and the healthy arms in all 39 patients. The ratio of healthy/diseased side of the mean blood pressure index increased from 0.62 +/- 0.11 preoperatively to 0.98 +/- 0.04 postoperatively (P < 0.01). The mean patency time for endovascular therapy and arterial bypass was (57.6 +/- 3.7) and (60.2 +/- 7.2) months, respectively.

CONCLUSIONSBoth endovascular therapy and arterial bypass have good curative effect for subclavian artery occlusion. Endovascular therapy is the preferred treatment for subclavian artery occlusion with mini-trauma and safety.
