Objective To examine the surgical treatments for obstructive jaundice caused by bile duct strictures after hepat-ic transcatheter arterial chemoembolization(TACE).Methods Clinical data were retrospectively analyzed of 9 patients who de-veloped bile duct strictures among 229 patients after TACE between June 1994 and March 2011 in People’s Hospital of Zhe-jiang Provincial and the Second Affiliated Hospital of Zhejiang University.There were 6 cases of primary liver cancer,and 3 ca-ses of metastatic liver cancer.Obstructive jaundice occurred 5 to 16 months after TACE treatment.The median time was 8 months.Results All the nine patients with bile duct strictures suffered different degrees of obstructive j aundice,which was cured after surgical operations or PTC + stenting in 7 patients and significantly relieved by percutaneous transhepatic cholangic drainage(PTCD)in 2 ones.Two patients with obstructive j aundice after TACE for primary liver cancer were followed up for 3 years,and no recurrence of hepatic carcinoma and bile duct obstruction was found.The other 7 patients were followed up for 3 to 13 months,and they all died of deterioration of primary disease.Conclusion Patients with obstructive jaundice caused by bile duct strictures after TACE benefit from surgical operations or intervention treatment.Different surgical strategies are selected based on the characteristics of primary disease,the site and extent of bile duct stricture.

To evaluate the effects of silicone points polishing on plaque index(PI) and sulcus bleeding index(SBI) after ultrasonic scaling. Forty patients with periodontal diseases were selected for ultrasonic scaling. After scaling,unilateral teeth were randomly assigned for silicone points polishing. PI and SBI were used to evaluate the effects of silicone points polishing. Silicone points polishing significantly reduced PI 12 weeks after scaling. Both in the polishing group and the control group, SBI decreased after scaling. The SBI in the polishing group was significantly lower than that in the control group in the 24 weeks. Silicone points polishing can effectively increase the smoothness of tooth and enhance the effects of uhrosonic scaling.

OBJECTIVE:To evaluate the clinical efficacy of Calcium Hydroxide Iodoform Glycerin(CHIG)paste for root canal disinfection.METHODS:145 patients(145 teeth)requiring root canal therapy were divided randomly into CHIG group,formo-cresol solution group(Group B)and camphor phenol group(Group C).After root canal preparation,the corresponding drugs were introduced into root canal and pulp chamber.The endodontic interappointment pain(EIP)and clinical efficacy in the 3 groups were compared.RESULTS:In Group A,the EIP incidence was the lowest(8.16%)while the effective rate was the highest(97.96%),showing significant differences as compared with Group B(31.91% and 68.09%,respectively)or Group C(34.69% and 71.43%,respectively)(P

Objective To explore the effects of salmeterol/fluticasone propionate complicated or combined with N-acetylcysteine on the pulmonary function and arterial blood gas analysis of the patients with chronic obstructive pulmonary disease (COPD), and to evaluate its curative effect.Methods 84 cases of COPD patients were randomly divided into combination treatment group (n=44)and simple treatment group (n=40).The patients in combination treatment group were treated with salmeterol/fluticasone propionate combinated with N-acetylcysteine while the patients in simple treatment group were treated only with salmeterol/fluticasone propionate, both of which were followed up for 6 months.The changes of pulmonary function (FEV1%FVC,FEV1%Pred,PEF daily variation rate:ΔPEF%)and the arterial blood gas analysis indexes (PaO2 and PaCO2 )of the patients in two groups were recorded before treatment, 3 months after treatment, and 6 months after treatment. Results The FEV1%FVC,FEV1%Pred and PaO2 of the patients in combination treatment group and simple treatment group were obviously increased 3 and 6 months after treatment compared with before treatment (P<0.01 ), and the PaCO2 were obviously decreased (P<0.01).And there were significant differences of the indexes mentioned above of the patients between two groups (P<0.05 );but the indexes of each group had no significant differences between 3 months and 6 months after treatment (P>0.05).TheΔPEF% of the patients in two groups had no significant differences between inter-group and intra-group before and after treatment (P > 0.05 ). Conclusion Combination of salmeterol/fluticasone propionate and N-acetylcysteine can obviously improve the pulmonary function and arterial blood gas analysis indexes of the COPD patients, which is superior to the simple application of salmeterol/fluticasone propionate and has definite and lasting curative effect on the treatment of COPD.

Objective To investigate the preoperative identification of esophageal submucosal tumor by endoscope. Methods 40 patients of esophageal submucosal tumors with lesions range from 1.0 to 2.0 cm from March 2012 to August 2016 were randomly divided into A, B groups. Patients in group A underwent submucosal tunneling endoscopic resection (STER) 3.0 cm from the lesions, while patients in group B first underwent submucosal injection of saline to mark the lesions, then perform STER in the same way. Then record the time of checking. Results The average time of group A was (420.0 ± 25.0) s, the average time of B group was (300.0 ± 25.0) s, there was statistical differences between the two groups. Conclusion Preoperative identification of the lesions before STER holds more advantages.

Objective To investigate the efficacy of anatomic plate internal fixation in treatment of complex proximal humeral fractures combined with humeral shaft fractures.Methods This retrospective case series study included 58 patients with complex proximal humeral fractures combined with humeral shaft fractures admitted from July 1998 to July 2015.There were 31 males and 27 females,with a mean age of 63 years (range,18-86 years).According to the Neer classification of proximal humeral fractures,three-part fractures were noted in 42 patients and four-part fractures in 16 patients.Four patients were combined with compressed or splitting fractures of the head of humerus and 38 patients with dislocation of the shoulder.According to the site classification of femoral shaft fractures,proximal 1/3 shaft fractures were noted in 36 patients,middle and distal 1/3 shaft fractures in 19,and multisegmental shaft fractures in three.All patients underwent anatomic reduction and anatomic plate internal fixation.Bone healing,Neer score of function outcome and complications were evaluated after operation.Results Mean duration of follow-up was 8.6 years (range,1-18 years).Bone union was observed in all patients after 10 to 24 weeks (mean,14.5 weeks).According to the Neer score,the outcomes were excellent in 23 patients,good in 25,fair in eight and poor in two,with the excellent rate of 83 ％.Complications such as infection,nerve injury and vascular injury were not observed after operation.Six patients suffered from limitations of shoulder anterior flexion and rise,one patient had humeral head necrosis and treated by shock wave treatment,and one patient had poor incision healing with hemorrhagic effusion and cured after dressing.Conclusion Anatomic plate internal fixation can contribute to fast functional recovery and few complications in treatment of complex proximal humeral fractures combined with humeral shaft fractures.

Objective To evaluate the effect of basic fibroblast growth factor(bFGF) on sheep bone marrow mesenchymal stem cells(BMSCs) proliferation and differentiation in vitro.Methods The sheep BMSCs were isolated and expanded in vitro and divided into experimental group and control group.bFGF(2 ?g?L-1) was added into cell culture medium of experimental group.In control group,no bFGF was added.The morphological differences of BMSCs between two group were observed.Growth curves and alkaline phosphatase(ALP) activity were assessed.In order to observe the influence of bFGF on differentiation potential of BMSCs,osteogenic and adipogenic inductions were conducted on BMSCs in two groups.Results Fibroblast colonies appeared 1 week after seeding of the mononuclear cells.2 weeks later,more colonies formed and each colony became larger.The cell number was 2.5 times of the control when the first passage cells grew to confluence and the ALP activity in experimental group was lower than that in control group(P
