Objective:To explore and compare the clinical efficacy of lyophilized recombinant human brain natriuretic peptide (Lrh-BNP) and dobutamine (Dob) in the treatment of patients with acute heart failure (AHF) and impacts on the plasma galectin (Gal)-3,Cystatin C (CysC) and endothelin (ET-)-1 levels.Methods:114 cases of patients with AHF in our hospital from February 2015 to February 2017 were selected as the research objectives and randomly divided into two groups.Dob group was treated by Dob,while Lrh-BNP group was treated by Lrh-BNP.The cardiac function parameters,plasma Gal-3,CysC,ET-1 levels before and after treatment,clinical comprehensive efficacy and incidence of adverse reactions were compared between two groups.Results:The FS,LVEF levels of both groups at 72 hours after treatment were significantly higher than those before treatment (P＜0.01),but the LVEDD,plasma Gal-3,CysC,ET-1 levels were obviously decreased (P＜0.01),the index mentioned above of Lrh-BNP group improved more significantly than those of the Dob group(P＜0.01).The overall effective rate of Lrh-BNP group was 89.5 ％,which was significantly higher than that of the Dob group (73.7％,P＜0.05).No significant difference was found in the incidence of adverse reaction between two groups(P＞0.05).Conclusion:Lyophilized recombinant human brain natriuretic peptide was more effective in the treatment of AHF than Dobutamine with equal safety,which might be related to the decrease of plasma Gal-3,CysC,ET-1 levels.

Objective To evaluate the combination use of transcatheter arterial chemoembolization (TACE), portal vein embolization (PVE) and high intensity focused ultrasound (HIFU) in treating portal vein tumor thrombus(PVTT). Methods A total of 85 patients with primary hepatocellular carcinoma complicated by PVTT, who were encountered during the period from Jan. 2011 to Feb. 2012 at authors’ hospital, were enrolled in this study. The patients were divided into the study group (n=47) and the control group (n=38). TACE, PVE and HIFU were performed in the patients of the study group, while only TACE and PVE were carried out in the patients of the control group. The therapeutic process was as follows: PVE was carried out 2 weeks after TACE was performed, and for the patients of the study group additional HIFU was conducted about 10 days after PVE procedure. Results The short-term effective rate in the study group and the control group was 89.4% (42/47) and 39.5% (15/38) respectively, and the difference between the two groups was statistically significant (P< 0.05). The 6-month, one-year, and two-year survival rate in the study group were 87.2%(41/47), 66.0%(31/47) and 27.7%(13/47) respectively; the median survival time was 15.4 months. In the control group, the 6-month, one-year, and two-year survival rate were 55.3% (21/38), 39.5% (15/38) and 10.5%(4/38) respectively;the median survival time was 10.3 months. The differences between the two groups were statistically significant (P< 0.05). Conclusion For the treatment of primary hepatocellular carcinoma associated with portal vein tumor thrombus, transcatheter arterial chemoembolization, portal vein embolization together with high intensity focused ultrasound is an safe and effective therapy as it can significantly improve the therapeutic effect and prolong the survival time.

Objective To investigate the effect of transcatheter bladder arterial chemoembolization on microvessel density(MVD)change in bladder cancer. Methods The MVD count of bladder cancer tissue of 30 patients before and after chemoembolization were examined by SP immunohistochemical staining.Cancer tissues were examined pathology after chemoembolization.All the cases were followed up for 12 to 36 months(mean 24.6 months),the 3 years survival rate was evaluated clinically. Results MVD counts were 69.8±3.4 and 56.4±3.3 before and after therapy respectively(P<0.05).Cancer tissues were severely damaged ultramicroscopically after interventional chemotherapy.The recurrent rate was 16.67%in 30 cases. Conclusions The chemoembolization could decrease MVD,improve survival rate and reduce the recurrence rate.

Objective To improve the method of blood collection from external jugular vein in rats,so as to repeatedly obtain blood samples of high quality and to meet the special requirements of the experiment.Methods The experimental rats were anesthetized by intraperitoneal anesthesia,and the jugular vein was fully exposed with special fixed method.Whereafter,the blood samples were collected by disposable vacuum blood vessels.Results This method had little traumatic effect.The blood samples were collected from 60 rats at an interval of 14 days with 1.8 to 2.5 mL each time.The success rate was above 95％,and the normal activities of the rats were not apparently affected.This vacuum blood collection method guaranteed the quality of serum,and the veracity of blood detection and analysis were also significantly improved.Conclusion On the basis of the principle of animal welfare,the improved rat jugular vein blood collection method has the advantages of simple operation,less trauma,large blood collection,high blood sample quality aod so on,which can ensure the effect of the special experiment.

Objective:To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately,and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.
