This paper aims to summarize the clinical application of interventional technique via portal venous system, laying stress on the necessity of reinforcing, improving and comprehensively applying this interventional technique, and to provide new conception concerning the diagnosis and therapy of the diseases involving portal venous system.

The paper described the conception and forms of risks for public hospitals financing,proposing the risk avoidance strategy, loss control strategy, and risk transfer strategy against these risks. In addition, it is proposed to take proactive measures to build the financing risk management system for public hospitals, and construct an effective financing risk prewaming mechanism, raise the scientific standard of financial decision-making, and develop a clear-cut economic responsibility system for the hospital leaders during their term, for the purpose of effectively minimizing the risks.

Objective To observe the clinical efficacy of acupuncture in treating primary hypertension and the effect of twirling reinforcing-reducing manipulations on the treatment of primary hypertension. Methods Totally 126 patients with primary hypertension were randomized into treatment group 1 of 40 cases, treatment group 2 of 44 cases, and a control group of 42 cases. The treatment groups were both intervened by acupuncture at Quchi (LI 11), while twirling reinforcing-reducing manipulations (twirling towards left) were applied in treatment group 1, while the manipulations (twirling towards right) were applied in treatment group 2;the control group was intervened by medication. The change of blood pressure after 10 min treatment was observed, and the clinical efficacies were compared. Results The total effective rate was 85.0%in treatment group 1, versus 88.6%in treatment group 2 and 61.9% in the control group, and the total effective rates in the two treatment groups were significantly different from that in the control group (P<0.05). In the two treatment groups, the systolic pressure and diastolic pressure respectively after 10 min treatment and 30 min treatment were markedly different from those 10 min before treatment in the same group (P<0.05). In the two treatment groups, the systolic pressure and diastolic pressure after 30 min treatment were markedly different from those after 10 min treatment in the same group (P<0.05). In the control group, the systolic pressure and diastolic pressure were significantly different from those 10 min before treatment in the same group (P<0.05). There were no significant inter-group differences in comparing the systolic pressure and diastolic pressure after 30 min treatment (P>0.05). Conclusions Acupuncture at Quchi (LI 11) is an effective approach in treating primary hypertension, and the reinforcing manipulation and reducing manipulation are both effective.

[Objective]To observe the clinical effect of the treatment of hyperplastic nonunion of the tibia with interlocking intramedullary nailing,fascia pedicled callus flap and bone grafting.[Method]Twelve cases of nonunion of the tibia were treated with intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting,and there were 8 males and 4 females.The patients age ranged from 26 to 64 years,with an average of 45 years.[Result]All cases were followed-up for an average of 48 months and achieved a solid union within 4～6 months.[Conclusion]Intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting have the design of the reasonable biomechanics,the function of untispinning and unticurtailing,less partial blood decompose.The fascia pedicled callus flap and iliac bone grafting could result in solid union and it is a recomment method for promoting bone-healing up after grafting and forming.

[Objective]To observe the change of children necrotic femoral head repairing under low stress environment and to explore the effect of low stress environment on Perthes disease.[Method]The sick coxa was supported by Coxa Multi-functional External Fixation Shoring Fixator,which decreased femoral head stress and creates a low-stress environment for the sick coxa.Meanwhile,the affected extremity was kept abduction and internal rotation in order to increase femoral head containment.The coxa could flex and extend partly on sagittal plane.Twenty-eight patients(32 hips) were followed up with mean follow-up time of 3 years and 5 months(2~7 years).The radiological characteristics of pre-and post-operation was analyzed.[Result]At 3 months postoperatively,joint space was broadened,high density necrosis shadow became little and little,the femoral head became full,height of the femoral head epiphysis increased.If epiphyseal nucleus fragmentation vaded epiphyseal plate,the big head and pachy-neck and the subluxation of coxa would finally result.[Conclusion]Under low stress environment,child necrotic femoral head could be repaired.The prognosis is related to Catterall stage of Perthes disease.On Catterall Ⅱ and Ⅲ stage,the curative effect is fairly good.But on Catterall Ⅳ stage,the curative effect is not evident.

Objective To explore the relapse,therapeutic effect,risk and prognostic factors of the pulmonary invasive fungal disease(IFD)in patients with a history of pulmonary IFD following allogeneic hematopoietic stem cell transplantation(allo-HSCT).Methods Fourteen patients with a history of pulmonary IFD received allo-HSCT between March 2005 and October 2006.Before transplantation,10 patients obtained complete remission(CR)and 4 partial remission(PR)after antifungal therapy.Antifungal prophylaxis was initiated on the first day of the conditioning therapy.Logistic regression models were used for multivariable analyses.Results The relapse rate of pulmonary IFD after allo-HSCT was 71.43%(10/14).Of 10 patients in CR,6 relapsed and all four patients in PR relapsed.Seven patients relapsed less than 3 months and 3 relapsed between four and six months after transplantation.Among the 10 patients with a history of IFD who relapsed after transplantation,9 patients received antifungal therapy,4 obtained CR,2 PR again and the other 3 didn't obtain remission.The effective rate of anti-fungal therapy was 66.67% and the pulmonary IFD-related mortality was 35.71%(5/14).There was no significant difference between amphotericin B,itraconazde and voriconazole for antifungal prophylaxis in patients with a history of pulmonary IFD(P=0.122).No risk and prognostic factors of the pulmonary IFD was identified by multivariable analyses.Conclusion Pulmonary was not an absolute contraindication for allo-HSCT,and patients with a history of pulmonary IFD had a higher relapse rate and transplant-related mortality after receiving allo-HSCT.

Objective To investigate the optimal interventional therapy for primary hepatocellular carcinoma (HCC) complicated by main portal vein tumor thrombus.Methods Three-stage treatment, i.e. transcatheter arterial chemoembolization (TACE) combined with portal vein stenting and 125I seeds strand implantation, biliary stenting plus 125I seeds strand implantation and endoscopic variceal ligation, was carried out in one patient with primary HCC complicated by main portal vein tumor thrombus. The clinical results were analyzed combined with a review of the relevant literature in order to compare the efficacies of various interventional therapies employed in clinical practice nowadays. Results The sequential therapies of the three-stage treatment program were successfully accomplished. The patient was followed up for over five years and lived well when the report was made. Conclusion At present, TACE combined with portal vein stenting and implantation of 125I seeds strand is the optimal treatment for primary HCC associated with portal vein tumor thrombus.

Percutaneous transhepatic biliary drainage(PTBD) is an effective therapeutic option for obstructive jaundice.With various novel puncture instruments being created,the manipulating technique being improved and medical idea being updated,PTBD has been widely employed in clinical practice for alleviating the biliary tract obstruction.In order to standardize this technique this paper aims to make some suggestions for the PTBD guidelines concerning the indications,contraindications,operative skill,postoperative management,complications and their preventions,points for attention,etc.

Objective To retrospectively analyze the mid-term clinical results of direct intrahepatic portosystemic shunt (DIPS) in treating patients with portal hypertension. Methods DIPS were created in 23 patients with portal hypertension. Both preoperative and postoperative portal systemic pressure gradient (PPG), liver function and clinical symptoms were recorded and compared. Shunt patency was checked by color Doppler ultrasonography and the data were statistically analyzed by Kaplan-Meier method. Results DIPS creation was successfully accomplished in all 23 patients. No serious complications occurred after DIPS except for hemorrhagic ascites (n = 1) and mild hepatic encephalopathy (n = 3). Mean PPG significantly decreased from preoperative (32.6 ? 5.3) mmHg with a range of (23 - 43) mmHg to postoperative (10.1 ? 2.7) mmHg with a range of (5-14) mmHg (P

Objective To evaluate the mechanism of altered gastrointestinal motility in portal hypertensive rats. Methods Thirty-two male Sprague-Dawley rats were divided into four groups:sham- operation control (SO, n=8), prehepatic portal hypertension by partial stenosis of the portal vein (PHPH, n=8 ), intrahepatic portal hypertension induced by injection of CCl 4 (IHPH, n=8), and intrahepatic portal hypertension with portacaval shunt (IHPH-PCS, n=8). Gastrointestinal myoelectrical activity and motility were monitored. Gastrointestinal hormones were measured with radioimmunoassay.Results Compared with SO rats, gastrointestinal motor index(MI) were reduced and abnormal myoelectrical activity were recorded (P
