Objective To investigate the experiences of combined liver-kidney transplantation (CLKTx).Methods Six patients underwent CLKTx in our center. The primary diseases included chronic glomerulonephritis and post-hepatitis B cirrhosis in 4 patients, hepatitis B virus associated nephritis and primary hepatocellular carcinoma in 1 patient, and polycystic kidney and polycystic liver in 1 patient. Cyclosporine A (or tarcrolimus), mycophenolate mofetil and methylprednisolone were applied to prevent rejection. Four cases of post-hepatitis B cirrhosis received lamivudine. And hepatitis B immunogloblin was given to 4 patients for a short term.Results All 6 liver grafts had good primary function. Five renal grafts had good primary function within one week post-transplantation. One patient with delayed kidney graft function needed supportive hemodialysis. The serum creatinine was declined to normal level 52 days post-operation. Pleural effusion occurred in all 6 patients among which 2 patients needed surgical drainage. Two patients had to be treated for bacterial pneumonia and pneumocystis carinii pneumonia respectively. Three patients needed lipid-lowering therapy at early time post-operation. At the last follow-up, all 6 patients were alive with normal renal graft function and liver graft function. The panel reactive antibody (PRA) of one patient was 23 % before transplantation, and remained at about 8 % post-transplantation. The serum HBsAg and HBV DNA of all 4 post- hepatitis B cirrhosis patients became negative post-transplantation.Conclusion CLTx is a safe procedure for combined hepatic and renal end-stage disease with excellent short-term results.

Objective To investigate whether the mortality and death causes of renal transplant recipients have changed from 1985 to 2002 in our center.Methods 145 cases of renal transplant recipients who died during 1985 to 2002 were divided into 3 groups: 1985 to 1990,1991 to 1996,1997 to 2002. The death causes and the mortality on the 1st ,2nd,3rd,4th and 5th year post transplant of each group were reviewed.Results During the three periods,the 1st,2nd,and 3rd year mortality was decreased. Infection as a cause of death fell from 31.8 % to 29.2 % and 26.7 % . Whereas death from liver disease,cancer and cardiovasvular diseases was increased.Conclusions The mortality is decreased. Infection,cardiovascular diseases,liver diseases and cancer were the main causes of death after transplantation from 1985 to 2002. It is important to prevent these diseases and treat them effectively in order to improve the recipients' survival rate.

Objective To investigate the effects of negative pressure wound therapy (NPWT) on the expression of EDA+ FN in granulation tissues of human diabetic foot wounds.Methods Forty patients with diabetic foot wounds fitting the inclusion criteria,admitted from Jan.2014 to Jun.2016,were randomly and equally apportioned to receive either NPWT or conventional gauze therapy (control) for 14 days.Granulated tissue biopsies were collected before (0 day) and after (14 day) treatment in both groups.All biopsies were subdivided into two parts.One part was preserved in 4％ paraformaldehyde for immunocytochemical staining of EDA+FN,and the other part was stored at-80 ℃ for Western blotting and PCR analysis of EDA+FN.Results The immunohistochemical analysis revealed that the mean area density of EDA+ FN increased in both NPWT group and control group at day 14 relative to day 0,but the change value of mean area density was higher in NPWT group than in control group (P＜0.01).Western blotting showed that the relative protein levels of EDA+FN increased in both NPWT group and control group at day 14 relative to day 0,but the change value of relative protein levels of EDA+FN was higher in NPWT group than in control group (P＜0.01).The real time PCR analysis demonstrated that the relative mRNA levels of EDA+ FN increased in both NPWT group and control group at day 14 relative to day 0,but the change value of relative mRNA levels of EDA+ FN was higher in NPWT group than in control group (P＜0.01).The results demonstrated the higher protein and mRNA levels of EDA+FN in NPWT group than that in control group.Conclusion NPWT obviously enhances EDA+FN expression in granulation tissue of diabetic foot wound,as a result promotes wound healing.

Objective To explore the efficacy of hormone replacement therapy (HRT) for rheumatoid arthritis (RA).Methods The literature about HRT in the treatment of rheumatoid arthritis were searched.Eleven papers were subjected to a Meta-analysis and a heterogeneity test was conducted to evaluate the efficacy of HRT.Results HRT reduced the level of erythrocyte sedimentation rate (ESR) in RA patients (P=0.016),the SMD was-0.22(-0.40,-0.04); improved bone mineral density (BMD) in RA patients (P=0.022),the WMD was 2.83(0.41,5.26); decreased clinical parameters for disease activity evaluations of RA patients (P=0.048),the SMD was-0.19 (-0.38,0.00); decreased the level of C-reactive protein (CRP) in RA patients,the SMD was-0.08 (-0.37,0.21),but the difference was not statistically significant (P=0.591).Conclusion The findings from this Meta-analysis indicate that HRT can reduce the ESR level,improve clinical indexes and improve BMD level of RA patients.HRT may suppress disease activity and osteoporosis of RA patients,so it may be used as an auxiliary therapy in the treatment of RA.

ObjectiveTo investigate the risk factors of metabolic syndrome ( MS ) in obese subjects.Methods A seven-year follow-up study was conducted in 413 simple obese subjects and 196 subjects with normal body weight who were recruited from community residents during physical examination in 2000.There was a 7 years follow-up.Anthropometrics,blood pressure,lipid profile,fasting blood glucose,and 2 h blood glucose after glucose loading were measured.Endothelium-dependent dilatation (EDD) test was also performed.Results Among 553 of 609 subjects who were followed up in 2007,there were 381 simple obese subjects ( simple obese group) and 172 normal weight subjects( normal weight group).Seven-year cumulative incidence of MS was 35.17％ in simple obese group and 8.14％ in normal weight group.In simple obese group,subjects with MS showed greater or higher levels of waist circumference( WC ),waist-hip ratio ( WHR ),triglyceride ( TG ),fasting plasma glucose ( FPG ),fasting insulin (FINS),and homeostasis model assessment for insulin resistance index (HOMA-IR) (all P＜0.05 ),and also decreased EDD( P＜0.05 ) as compared with those without MS.WC,WHR,and FINS were higher( all P＜0.05 ) and EDD was lower( P＜0.05 ) in subjects with MS of normal weight group than those without MS.Logistic analysis showed that the male gender,WC,WHR,FPG,HOMA-IR,and EDD were major risk factors of MS.Conclusion Central obesity,insulin resistance,and endothelial dysfunction are important independent risk factors for development of MS.

ObjectiveTo investigate the value of strain ratio (SR) in the diagnosis of Hashimoto's thyroiditis.Methods 116 patients who had been diagnosed clinically as Hashimoto' s thyroiditis were enrolled in the study.Those patients were classified into four groups:the hyperthyroidism group,the euthyroidism group,the subclinical hypothyroidism group,and the clinical hypothyroidism group.50volunteers with normal thyroid functions were enrolled as a control group.SR of the thyroid and sternocleidomastoid muscle of same side was calculated.The correlation coefficient between the elasiticity SR and the serum thyroid stimulating hormone (TSH) was evaluated and their differences in the diagnosis of Hashimoto's thyroiditis were compared.ResultsThe Spearman's correlation coefficient between the SR and the serum TSH was 0.605,which was significant (P =0.000).The SR increased in an ascending order among the group with hyperthyroidism,the control group,the group with euthyroidism,the group with subclinical hypothyroidism,and the group with clinical hypothyroidism.ConclusionsElastography SR is valuable way for evaluating the progression of Hashimoto's thyroiditis.

Objective To analyze imageology appearance and clinical characteristics of the cystic and solid breast carcinoma.Methods Features of MRI and B-type ultrasonic inspection of 26 patients with the cystic and solid breast carcinoma pathologically confirmed (15 patients with mucinous carcinoma,6 patients with intracystic papillary carcinoma,5 patients with squamous cell carcinoma of the breast) were retrospectively reviewed.Results In terms of clinical appearance,the incidence of the squamous cell breast carcinoma with an average age of 70.1 years old was larger than in youth,while mucinous carcinoma with an average age of 67.7 years old and intracystic carcinoma of breast with an average age of 55.1 years old were contrary.The squamous cell breast carcinoma developed more quickly than mucinous carcinoma and intracystic carcinoma of breast.The squamous cell breast carcinoma often occurred around mammilla (4/5),while the mucinous carcinoma and intracystic papillary carcinoma often occurred upper outer quadrant of breast,which was similar with other breast cancer.The average size of 49.6 mm in the squamous cell breast carcinoma was largest than the average size of 25.1 mm in mucinous carcinoma and the average size of 35.2 mm in intracystic papillary carcinoma.The malignant degree of squamous cell breast carcinoma was higher than mucinous carcinoma and intracystic papillary carcinoma,which intended to occur lymph node metastasis and skin infiltration.The diagnosis probability of mucinous carcinoma was smaller than intracystic papillary carcinoma through preoperative puncture,while squamous cell breast carcinoma was larger.On the MRI imageology appearance,both types of breast cancer had the same shape of rotundity or lobulated.The tumors were low signal on T1WI and partially high signal on T2WI,which were circular enhancement after enhancement.However,the edge of mucinous carcinoma and squamous cell breast carcinoma was rougher than intracystic papillary carcinoma compared with squamous cell breast carcinoma.The bursa wall of mucinous carcinoma was more uniformity,while papillary soft tissue image can be found in intracystic papillary carcinoma,which was enhanced significantly after enhancement.In terms of ultrasonic sound (US),there were low echo signal and high echo signal on the back of tumor compared with other breast tumor.There were shadow beside mucinous carcinoma.Squamous cell breast carcinoma was rich in blood supply,while mucinous carcinoma and intracystic papillary carcinoma were opposite.Conclusion Histological type of cystic and solid breast carcinoma is complex,but the appearances of MRI and US have some characteristics.Histological type and the range of disease could be guessed through the combination of preoperative puncture and clinical appearance,which plays an important role in operation mode and treatment guidance.
