Objective To investigate the adverse reactions and survival rate of low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in treatment of elderly patients with primary hepatic carcinoma.Methods A total of 84 patients with primary liver cancer were enrolled and randomly divided into low dose group and high dose group.Patients received 40 mg/m2 and 80 mg/m2 of Oxaliplatin respectively,and adverse reactions and survival rate were compared between the two groups.Results Incidence of nausea and vomiting was obviously lower and the number of patients with pain scale above 6 was significantly smaller in low dose group than in high dose group,with statistically significant differences (11.9％ vs.21.4％ and 28.6％ vs.78.6％,x2 =9.910,20.056,both P ＜ 0.05).White blood cell count was significantly higher and alanine aminotransferase (ALT) was significantly lower in low dose group than in high dose group after treatment (t =13.447,6.774,both P＜0.05).1 year and 3 year survival rate was 69.05％ and 30.95％ in low dose group and 61.9％ and 21.43％ in high dose group,respectively,with no statistically significant difference (x2 =0.474 and 0.985,P=0.491 and 0.321).Conclusions Low dose of Oxaliplatin combined with transcatheter arterial chemoembolization in the treatment of elderly patients with primary hepatocellular carcinoma is worth to be promoted in clinical application because it does not affect the patient survival rate and the toxic effects of the chemotherapy are very little.

Objective To evaluate the effects(mortality, amputation rate, the length and expense of hospital stay, etc)of the obstructing blood flow interventional embolectomy and simple interventional embolectomy for acute lower limb arterial embolism. Methods 79 cases of acute lower limb arterial embolism including 23 cases of two sites puncturing and obstructing blood flow interventional embolectomy and 56 cases treated by simple interventional embolectomy were retrospeetively analyzed and compared. Results Embolisms were removed in all 79 cases and arteries were reopened successfully. The mortality and the amputation rates of the simple and the obstructing blood flow embolectomies were 5.36%,19.6%, and 4.35%, 8.70% respectively. Conclusion Two sites puncturing and obstructing blood flow interventional embolectomy for acute lower limb arterial embolism is simple, safe and effective, comparing with the simple interventional embolectomy, with lower amputation rate, quicker recovery and lower expense, however with no statistical significance in mortalities.

Objective:To evaluate the clinical significance of patent accessory hepatic vein (AHV) in treatment of Budd-Chiari syndrome (BCS) with hepatic vein occlusion.Methods:The clinical data of 21 BCS patients treated from Jan 2010 to June 2019 were retrospectively analyzed. All patients underwent AHV and IVC venography.Results:Angiography showed that the diameter of AHV was 6-13mm after the procedure, the angle between AHV and the distal end of IVC was (106.9±27.7)°, and 57.1% of the AHV were opened at the right side of IVC, 9.5% at the front, and 1.4% at the left side, respectively. The technical success rate was 100%. Thirteen patients with AHV disease underwent balloon dilatation angioplasty, and their preoperative AHV pressure dropped from (41.6±6.4) cm H 2O to (22.2±5.5) cm H 2O ( t=11.966, P<0.01). The preoperative AHV and intrahepatic IVC pressure decreased from (29.1±3.3) cm H 2O to (19.1±8.8) cm H 2O ( t=8.136, P<0.01) and from (25.5±6.1) cm H 2O to (13.8±4.0) cm H 2O ( t=5.536, P<0.01), respectively. All patients were of no symptom during follow up for 6 months and ultrasound showed that the patency rate of original lesion was 100%. Conclusion:A patent AHV helps alleviate the symptoms and blood congestion of BCS patients with hepatic vein obstruction.

Conclusion The rehabilitation service should be developed; the quantities and quality of the rehabilitation medical professionalsshould be improved, the classified structure and the service objects are unbalanced.

BACKGROUND:The non-steroidal antiinflammatory drugs (NSAIDs) were widely used to prevent heterotopic bone formation following total hip arthroplasty (THA),however,its efficacy and safety is poorly understood.OBJECTIVE:To determine the efficacy and safety of postoperative NSAIDs therapy in patients undergoing THA using Meta analysis.METHODS:The databases of PubMed,Embase,Cochrane Library,Chinese biomedical literature,CNKI,VIP as well as bibliographies of retrieved articles were researched for randomized controlled trials comparing NSAID versus control after THA,and the data were analyzed using Review Manager 5.0.RESULTS AND CONCLUSION:A total of 13 randomized controlled trials totaling 4706 participants were included.The result of meta analysis showed that low dose aspirin did not significantly affect the incidence of heterotopic bone formation (HBF) [RR=0.99,95% CI (0.87,1.14) rather than medium to high dose NSAIDs [RR=0.44,95% CI(0.30,0.64),there was no significant difference between two group in hip pain and physical function,the incidence of HBF was 16.0% in NSAID-group and 11.1% in 7 Gy group.Apart from low dose aspirin,medium to high doses of postoperative NSAIDs produce a substantial reduction in the incidence of HBF at the cost of minor high gastrointestinal side effect.Limited evidence showed there were no significant differences between the groups for improvements in hip pain and physical function,7 Gy fraction is more effective than use of NSAID.

Objective To assess value of serum level of ischemia modified albumin (IMA) in diagnosis for myocardial ischemia of coronary artery disease (CAD). Methods Seventy-two patients with clinically suspected myocardial ischemia of CAD admitted to The First People's Hospital of Hangzhou during November 2009 to May 2010 ready for undergoing coronary angiography, the gold standard for diagnosis of CAD, were randomly selected for the study. The patients were divided into CAD and non-CAD groups based on their coronary angiography. Serum level of IMA was determined with cobalt-albumin binding ( ACB) assay before coronary angiography, which served as diagnostic standard for CAD. Logistic regression analysis method was used to evaluate varied levels of IMA with area under the receiver operating characteristic curve (AUCROC) in diagnosis for myocardial ischemia of CAD. Results Mean level of IMA was (97 ±24) U/ml and (81 ±15) U/ml for CAD group (n =51) and non-CAD group (n =21), respectively. Sensitivity and specificity of a cut-off value of IMA 83.69 U/ml in diagnosis for myocardial ischemia of CAD was 80 percent and 57 percent, respectively, with a predictive value of a positive test 82 percent and that of a negative test 55 percent, respectively, from AUCROC. Logistic regression analysis demonstrated that both hypertension (P=0. 022, 6 = 1.421, OR=4. 141) and level of IMA (P=0.003, b= 1.780, OR=5.928) were independent predictors for CAD. Conclusions Sensitivity, specificity and predictive value of a positive test of the level of IMA are relatively high in diagnosis for myocardial ischemia of CAD, which is an independent predictor of it.

A 21-year-old male was hospitalized for recurrent swelling of lower limbs (lymphedema) for 1 year and worsening of it for 1 week.Physical examination revealed several smooth,firm enlarged lymph nodes of the neck,groin without apparent tenderness measuring about 1 cm in diameter.Cardiac and pulmonary auscultation showed no obvious abnormality.The abdomen was soft on palpation without tenderness or rebound tenderness.Skin examination revealed swelling of both lower limbs,especially the left lower limb,as well as scattered irregularly sized,dark erythematous patches with a wood-like consistency on the swollen lower limbs,with high temperature but no tenderness.Elevated peripheral eosinophil count was observed before and after admission,with the eosinophil percentage higher than 70％.Vascular ultrasonography showed thrombosis in the right anterior tibial artery,left dorsal artery of foot and lower portion of the left great saphenous vein.Multiple enlarged lymph nodes were found by computed tomography in the mediastinal,bilateral axillary,retroperitoneal regions and around the abdominal aorta.Lymph node and bone marrow biopsies showed eosinophilia.Histopathology of lesions on the extensor aspect of the left medial thigh and left lateral malleolus showed massive eosinophilic infiltration and lymphatic dilation in the dermis,as well as eosinophil emboli in some lumens.The FIP1L1-PDGFRA fusion gene was undetected.A diagnosis of idiopathic hypereosinophilic syndrome was finally made.The symptoms rapidly regressed after glucocorticoid treatment.

BACKGROUND:Due to limitations of the physicochemical properties of soft denture liner material itself, whisker has been added in the soft lining material in recent years, so as to enhance its mechanical properties. OBJECTIVE:To investigate the effect of different additive amount of anhydrous calcium sulfate whisker on the mechanical function of self-curing soft denture liner. METHODS: There were six groups in this experiment. Anhydrous calcium sulfate whisker at the mass fraction of 0 (control), 1%, 2%, 3%, 4%, 5% was respectively added into self-curing soft liner materials, 10 test specimens in each group, a total of 60 test specimens. The shear bond strength, Shore hardness and tensile strength were detected. RESULTS AND CONCLUSION: With the increasing amount of the anhydrous calcium sulfate whisker, the Shore hardness of the soft lining material was increased continuously, and the tensile strength was increased firstly and then reduced. When 3% anhydrous calcium sulfate whisker was added, the bond strength and tensile strength of soft lining material reached the peak. Taken together, the mechanical properties of the soft lining materials became perfect when 3% anhydrous calcium sulfate whisker was added. These results demonstrate that anhydrous calcium sulfate whisker may affect the mechanical properties of self-curing soft liner.
