RESUMO
ObjectiveTo characterize the prevalence and epidemic situation of imported malaria cases in Songjiang District of Shanghai from 2013 to 2022， and to provide evidence for malaria prevention and control. MethodsRelated data were collected and analyzed， including malaria cases， blood testing of febrile patients， and mosquito surveillance in Songjiang from 2013 to 2022. ResultsA total of 13 002 febrile patients in Songjiang were tested for plasmodium parasites from 2013 to 2022， among which 18 malaria cases were confirmed， including 17 cases of falciparum malaria and 1 case of ovale malaria. Moreover， a total of 36 malaria cases were notified in Songjiang through the National Notifiable Disease Reporting System from 2013 to 2022， including cases reported from Songjiang District and other districts or provinces with physical addresses in Songjiang. Of them， there were 31 cases of falciparum malaria， 2 cases of vivax malaria， 2 cases of ovale malaria and 1 case of quartan malaria. The gender ratio of male to female cases was 17∶1， and the majority was young and middle aged. In addition， 35 cases were imported from Africa and 1 case from southeast Asia； 34 cases were migrant workers， and 2 cases were travellers abroad； 17 cases were found and reported in Songjiang， 15 cases were reported from other districts of Shanghai， and 4 cases were reported from other provinces； 27 cases were treated in Shanghai， 3 cases were treated in other provinces and 6 cases were treated with self-provided antimalarial drugs. Mosquito surveillance in Songjiang showed that density of Anopheles sinensis was extremely low. ConclusionNo indigenous malaria case has been notified in Songjiang since 2008. Malaria surveillance on migrant workers remains the focus of malaria prevention and control. Furthermore， achievement of malaria elimination in Songjiang should be continually enhanced to avoid potential further transmission of imported malaria.
RESUMO
Objective To evaluate the clinical effect of endovascular interventional therapy in treating Cockett syndrome associated with deep vein thrombosis (DVT) of left lower extremity.Methods The clinical data of a total of 256 patients with Cockett syndrome complicated by DVT of left lower extremity,who were admitted to authors' hospital during the period from January 2011 to January 2015,were retrospectively analyzed.The patients were treated with catheter-directed thrombolysis,balloon dilatation of the occluded or narrowed venous segment,and/or stent implantation.The circumference differences of the affected limbs before and after treatment and the long-term patency rates were compared.Results Of the 256 patients with Cockett syndrome complicated by DVT of left lower extremity,complete dissolution of thrombus was achieved in 232 (90.6％) and partial dissolution of thrombus in 24 (9.4％).The circumference difference of thigh and calf was (7.12±2.15) and (4.57±2.81) cm respectively before and after treatment.Iliac vein reconstruction was carried out in 206 patients,among them simple balloon dilatation was employed in 46 and balloon dilatation together with stent implantation was adopted in 160.The patients were followed up for 9-24 months with a mean of 15 months.In simple balloon dilatation group,3 patients lost touch with the authors during the following-up period,26 patients (60.5％) developed iliac vein occlusion and post-embolization syndrome occurred in 21 patients (48.8％).In balloon dilatation plus stent implantation group,11 patients lost touch with the authors during the following-up period,stenosis or occlusion of the stent was seen in 13 patients (8.7％),post-embolization syndrome was observed in 15 patients (10.1％).The differences in vascular stenosis or occlusion and in the occurrence of post-embolization syndrome between the two groups were statistically significant (P＜0.001).Conclusion For the treatment of Cockett syndrome complicated by DVT of left lower extremity,catheter-directed thrombolysis and balloon dilatation combined with stent implantation carry definite clinical curative effect.
RESUMO
The onset of hepatocelluar carcinoma, one of the serious complications of primary Budd-Chiari syndrome, is associated with poor prognosis.Although so, the diagnosis and treatment of such disease has still not been standardized at recent.In this paper, we overviewed the recent advances on Budd-Chiari syndrome associated with hepatocelluar carcinoma.
RESUMO
Purpose To investigate the expression of IMP3 and its relationship with clinicopathological characteristics in breast cancer.Methods By the tissue microarray technique and immunohistochemical EliVision two-step method, expression of IMP3 was detected in 214 cases of breast carcinoma.Results Of the 214 breast cancer cases,IMP3 expression was seen in 31(14.49%). IMP3 expression in the tumor cells was positively correlated with histological grade (P=0.005), proliferative index labeled by Ki-67 (P=0.033) and triple negative phenotype (P0.05).Conclusions Expression of IMP3 is correlated with higher histologic grade, higher proliferative activity and triple negative breast carcinoma.Our findings indicate that IMP3 plays an important role in breast cancer progression, and IMP3 could be an adjuvant diagnostic marker in triple negative breast carcinoma.
RESUMO
Objective To evaluate the correlation between regional blood perfusion,metabolism and angiogenesis in breast cancer.Methods The PET/CT functional imaging technique was applied to quantitatively detect the central and marginal blood perfusion parameters including blood flow(BF),blood volume(BV)and permeability of surface(Ps),and metabolism index of standard uptake value(SUV)of the tumor in 33 breast cancer patients.The expression of CD31.CD105 and VEGF in paraffin section of breast cancer were detected by immunohistochemical method,then MVD(CD31)and MVD(CD105)were obtained.The relationship between the regional blood perfusion and metabolism and MVD(CD3 1),MVD(CD105)and the expression of VEGF were analyzed. Results There was significant correlation of MVD (CD31)with BF of marginal region(P<0.05).There were significant correlations of MVD(CD105)with BF.PS and SUV(P<0.05). Conclusions Regional blood perfusion,metabolism is correlated with angiogenesis in breast cancer tissue.PETT/CT regional blood perfusion and metabolic imaging iS a noninvasive method which can be used to estimate angiogenesis status clinically in breast cancer.
RESUMO
Objective To study the influence of RNA interference Caspase-3 gene on apoptosis of transformed human embryonic kidney 293 cells induced by cadmium in vitro. Methods Transformed human embryonic kidney 293 cell were treated with siRNA for 36 h. The treated cells were incubated with 40 ?mol/L CdCl2 for 12-24 h and the cells viability were measured with methyl thiazolyl tetrazolium(MTT) assay. In addition,the expression of caspase-3 gene in 293 cells was detected by the methods of reverse transcription polymerase chain reaction (RT-PCR) and Western-blot analysis,and the occurrence of apoptosis was determined by flowcytometry with Annexin-V and propidium iodide (PI) double labeling method. Results The results of RT-PCR and Western-blot analysis revealed that in incubated cells with 40 ?mol/L cadmium 12 h,the expression of Caspase-3 mRNA and 20 kDa protein significantly increased when compared with controls(n=4,P

RESUMO
0.05). Conclusion: The short-term clinical result indicates that resin-bonded CBW may be used as fixed prostheses to replace lost single anterior or premolar teeth with minimum preparation of abutment teeth. This restoration does not adversely influence the health of dental pulp and periodontal tissues.
