Objective To observe the effect of combination of dexmedetomidine and sufentanil on postoperative analgesia for the highly nicotine dependent patients undergoing esophagectomy. Methods Ninety highly nicotine dependent patients undergoing esophagectomy were randomly allocated into three groups (n = 30 each): low-dose sufentanil group (Group S1), high-dose sufentanil (Group S2), dexmedetomidine and sufentanil group (Group DS). All patients of three groups received postoperative PCIA with following setting: 2 mL/h;bolus: 2 mL; lock time: 5 min; 4 hours limited: 40 mL. The scores of VAS and Ramsay, effective presses/total presses of PCIA, the consumption of sufentanil during 72 h after operation, side effects and the satisfaction degree of patients were recorded. Results Compared with those of group S2, the scores of VAS (both at rest and movement) decreased significantly in group DS from 1 h to 8 h (P<0.05). Compared with those of group S1, the scores of VAS (both at rest and movement) decreased significantly in group S2 and DS from 1 h to 72 h (P<0.05). Compared with that in group S1 and S2, the consumption of sufentanil during 72 h after operation decreased significantly in group DS (P < 0.05). Compared with those in group DS, The numbers of nausea and vomiting were significant decreased in group S1 and S2(P < 0.05). Compared with those in group S1, the remedial cases were significantly decreased in group S2 and group DS (P < 0.05). Conclusion The effect of combination of dexmedetomidine and sufentanil is superior to that of sufentanil in terms of postoperative analgesia in highly nicotine dependent male patients undergoing esophagectomy.

Objective Fabry' s disease is a rare X-linked recessive disease. Its cardiac manifestations are not well recognized. Methods The data of 3 patients from different Chinese kindreds with Fabry's disease and cardiac manifestations who seeked medical advice in our department in 2007 were analyzed. The age, sex, family history, main symptoms, ECG and echocardiographic findings were recorded for all the patients. The diagnostic criteria of Fabry's disease was based on α-galactosidase (α-GAL) quantity in white blood cells. Results All of the patients were female. Their age was from 41 to 57. Two of them had the typical symptoms of Fabry's disease in their young age. All of them had family history of the disease and cardiac symptoms. ECG showed ST-T change and echocardiography showed hypertrophy of left ventricule of different degrees. Their α-galactosidase level in white blood cells was lower than normal. The α-galactosidase level in patient 1 was the lowest. Her cardiac symptoms were most serious in the three patients and she had involvement of other organs. Conclusion Patients with Fabry's disease may have cardiac manifestations. Family history, typical symptoms in young age and the characteristics of multi-systemic disorder are helpful clues to the diagnosis.

Objective To investigate the effect of simvastatin on heme oxygenase (HO) -1expression and ventricular remodeling in rats with non-ischemic heart failure. Methods Seventy eight male Wistar rats were randomized into three groups: normal control group (n = 18), model group and simvastatin group (n= 60). Male Wistar rats in model and simvastatin group were given adrimycin(ADR) in an accumulated dose of 15 mg/kg for two weeks (2.5 mg /kg, peritoneal injection, three times per week), and 8 rats were dead. The survival rats (n= 52) were then randomly divided into two groups: model group (n=26) and simvastatin group (n=26), and 6 rats were dead in model group, while 7 dead in simvastatin group at the end of the study. Then rats in simvastatin treatment group(n=19)were given simvastatin 20 mg·kg-1·d-1 by gavage for four weeks,and rats in model group (n=20) and in control group (n=18) were treated with 5% glucose by gavage.At the forth week, another 9 rats were selected into the study and given ADR with an accumulated dose of 15 mg/kg for two weeks. The hemodynamics, mRNA expression of HO-1 in myocardium, left ventricular function as well as hydroxyproline were measured at the end of the sixth week. Results At the sixth week, compared with control group, systolic (+) and diastolic (-) function of the left ventricule (±LVdp/dtmax) of rats in model group and simvastatin group were reduced significantly, and the reduction amplitudes of + LVdp/dtmax and -LVdp/dtmax were 28.2%, 11.9% and 33.0%,27.9%,4, respectively (F = 4.899,3. 890, all P<0.01). The + LVdp/dtmax of rats in simvastatin group was higher than that in model group (F= 2.461, P<0.05). The content of myocardium hydroxyproline was elevated from the end of the second week [(485.0±52.9)g/kg vs. (364.0±41.6)g/kg,F=0.441 ,P<0.01]. At the end of the sixth week, the content of myocardium hydroxyproline of model group elevated continuously [(572.9±75.4) g/kg vs. (485.0±52.9)g/kg, F=0.654,P<0.05], but not for simvastatin group [(475.9±86.5) g/kg vs. (485.0±52.9)g/kg, P>0.05]. The mRNA expression of HO-1 in myocardium 'in model group was higher than that in control group [(0.6217±0.1229) vs. (0.2475±0.1053), F = 0.128, P < 0.01]. The mRNA expression of myocardium HO-1 was increased further by simvastatin treatment [(0.7860±0.1133) vs. (0.6217±0.1229),F=3.622,P<0.05]. Conclusions Compared with control group, the myocardial HO-1expression of heart failure rats is increased. Simvastatin treatment enhances the myocardium HO-1 expression further and alleviates myocardial injury and the degree of heart failure.

Objective The aim of this study was to investigate the differences on origin distribution and radiofrequency ablation characteristics between premature ventricular contractions (PVC) from left and right ventricular.Methods A total of 354 frequent PVC patients were enrolled.Two hundred and eighty patients were PVCs with right ventricular origin (group RV) and 74 patients with left ventricular origin (group LV).The age,gender,ablation power,temperature and duration,time of target potential before QRS onset,fluoroscopic time,procedure time and success rate were compared between the two groups.Results Majority PVCs (79.10％) were of right ventricular origin,in which the most common site was at right ventricular outflow tract (RVOT) (55.93％);whereas,only 20.90％ were of left ventricular.There were significantly differences between group RV and group LV in age [(44.7 ± 13.6) yrs vs (49.6 ±15.9) yrs,P =0.017],gender [male:35.4％ (99) vs 55.4％ (41),P =0.002],time of target potential before QRS onset [(37.9 ± 16.2) msvs (31.3 ± 11.7) ms,P=0.008],procedure time [(85.1 ± 36.9) minvs (100.8 ± 45.5) min,P=0.017],fluoroscopic time [(12.3 ± 9.2) min vs (15.9± 10.8) min,P =0.028] and success rate (96.4％ vs 89.2％,P =0.012).Conclusions Radiofrequency ablation of PVCs was a safe and effective method.Subjects with RV PVCs are younger and more females than subjects with LV PVCs.The radiofrequency ablation for RV PVCs was easier,and the success rate was higher than that for LV PVCs.

A 57-year-old man was admitted to the hospital for a 7-year progressively spreading plaques involving the entire body surface, and multiple irregularly sized red nodules and infiltrated patches on the face, trunk and limbs. Histopathological examination showed pleomorphic tumor cells diffusely dis-persed throughout the dennis, giving an appearance of low proliferation. Some cells with cytoplasmic pro-cesses appeared multiangular in shape, lmmunohistochemically, tumor cells were negative for CDla or S-100, but positive for CD45, FXIIIa, CDl4, MHC- Ⅱ, CD68 and lysozyme with extracellular interstitial expression. Ultrastructurally, the cells exhibited cytoplasmic processes and irregularly sized nuclei; no Birbeck granules were observed. Vesicules of low electron-density were seen diffusely in cytoplasm and extracellular matrix. The case is herein diagnosed as cutaneous non-Langerhans cell histiocytosis, which presents with a chronically invasive clinical course. These cells may develop from immature dermal dendritic cells.
