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 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 dosimetric characteristics and their clinical applications of volumetric modulated Arc therapy (RapidArc) with fixed-fields intensity modulated radiotherapy for early stage nasal NK/T-cell lymphoma.Methods Ten patients with stage Ⅰ E and Ⅱ E nasal NK/T-cell lymphoma were enrolled in the study.Five field coplanar plan (5F),nine field coplanar plan (9F),five field non-coplanar plan (5F-N) and RapidArc plans were designed for each patient,in which 5F plan was set as the control group.Conformity index (CI) and homogeneity index (HI) as well as the maximum dose of organs at risks were compared.Results The target CI of 5F,9F,5F-N and RapidArc plan was 0.419±0.159,0.478 ±0.181,0.465 ±0.121 and 0.518 ±0.111,respectively.Compared with 5F (0.136±0.038),the target HI of 9F and RapidArc plan was 0.111 ±0.027 and 0.112 ±0.031 (t =3.11,3.04,P ＜ 0.05).9F plan significantly increased the Dmax of lens in the contralateral side(t =2.82,P ＜ 0.05) and in ipsilateral side (t =3.25,P ＜ 0.05),while 5F-N plan decreased the Dmax of optical nerves by up to 9％.RapidArc plan effectively reduced the radiation to organs at risk in lens (t =3.25,P ＜0.05),eyes (t =3.25,P ＜0.05),optical nerve (t =2.57,P ＜0.05) and optical chaism(t =7.62,P ＜0.05).The delivery efficiency of four plans ranked as RapidArc ＞ 5F ＞ 5F-N ＞ 9F.Conclusions RapidArc produced statistically significant improvement in the dose distributions of targets,and also reduced the Dmax of organs at risk,which would be the better choice of radiotherapy for nasal NK/T-cell lymphoma.

Objective To investigate the clinical and radiologic features of posterior reversible encephalopathy syndrome (PRES) associated with preeclampsia-eclampsia.Methods Twenty-one cases of PRES associated with preeclampsia-eclampsia were retrospectively studied on some aspects of clinical and radiologic features.Results The most common clinical presentations were seizures( 18 cases ),headache (16 cases),altered mentation (15 cases) and vision change (12 cases). Vasogenic edema lesions distributed in the parietal or occipital lobe (20 cases),the frontal lobes (14 cases),temporal lobes ( 11 cases), and basal ganglia (11 cases). The splenium involvement occurred in 4 cases,cerebellar hemispheres and brain stem involvement was prcscnted in 3 cases and 1 case separately. Three major patterns of PRES included dominant parietal-occipital (7 cases),the holohemispheric watershed (7 cases),and superior frontal sulcal (6 cases).Partial and asymmetric expression of PRES only occurred in 1 case.Conclusions The clinical features of PRES associated with preeclampsia-eclampsia are typical.Except the parietal or occipital lobe,involvement of the frontal lobe,temporal lobe and basal ganglia is common,followed by the occasional presence of the splenium,cerebellar hemispheres and brain stem.Three primary PRES patterns are noted,occasional with partial and asymmetric expression of PRES. Awareness of these typical and variable characteristics is important to recognize the PRES ncurotoxicity morc accurately when PRES present.

Objective:To explore the changes of NK and NKT cells and the expression levels of their activated, inhibitory receptors in the peripheral blood of patients with newly diagnosed rheumatoid arthritis ( RA), and to reveal the potiential role of NK and NKT cells played in the pathogenesis of RA.Methods:32 patients with new onset RA and 15 healthy controls were recruited.Activated and inhibitory NK and NKT cells in peripheral blood were quantified by flow cytometry.The frequency of spontaneous and stimulated IFN-γ+NK and NKT cells and CD107aγ+NK cells were examined.Finally,the potential relationship between the frequency of NK and NKT cells subsets and clinical indexes were analyzed.Results:The frequencies of NK cells in peripheral blood in RA patients were sig-nificantly lower than those in the controls ( P=0.026 ).The frequencies of NKG2D+, NKP46+activated NK cells and NKG2C+, NKG2D+,NKP46+activated NKT cells in RA patients were significantly higher than those in the controls (P=0.011,P=0.010,and P<0.001,P=0.032,P=0.001,respectively),whereas the frequencies of KIR2DL3+,KIR3DL1+and NKG2A+inhibitory NK cells and KIR2DL3+,NKG2A+inhibitory NKT cells in RA patients were significantly lower (P=0.002,P=0.002,P=0.014,and P=0.027,P=0.002,respectively).Moreover, the frequencies of stimulated IFN-γ+NK cells and IFN-γ+NKT cells, spontaneous and stimulated CD107 aγ+NK cells in RA patients were significantly higher than that in the controls ( P=0.037, P=0.004 and P=0.001, P=0.001, respectively).Furthermore,the frequencies of NK cells,NKG2Aγ+and KIR2DL3γ+inhibitory NK cells were correlated significantly with the values of DAS28 in RA patients (r=0.357,P=0.045;r=0.399,P=0.024;r=0.468,P=0.021,respectively).Conclusion:Lower frequencies of NK cells, higher frequencies of activated NK cells and activated NKT cells, lower frequencies of inhibitory NK cells and inhibitory NKT cells, and higher NK cell activity may induce the autoimmune reaction involved in the pathogenesis of RA.
