A total of 135 patients diagnosed with Budd-Chiari syndrome(BCS)during August 2004 and February 2007 were reviewed and analyzed retrospectively.The results showed that 105 subiects (77.8%)caused by malignances,while 29 participants(21.5%)had no definite pathogens.The most commonly seen symptom included jaundiee(69.6%),followed by ascites(48.2%),abdominal distention (40.7%)and lower extremity edema(37.0%).Hisher levels of STB,PT and γ-GT were determined.Color Dopple ultrasound,CT and MRI could be helpful in diagnosing BCS;angiography remained the most accurate measurement.Main treatment strategies were stent implantation and/or balloon dilation.BCS is a clinical syndrome with no typical symptoms.which makes its management very difficult.A complete understanding of the condition will help reduce misdiagnosis.Angiography and stent implantation are primary ways to diagnose or treat BCS.

Objective To investigate the effects of cardioplegic solution containing different concentrations of emulsified isoflurane on myocardial ischemia-reperfusion injury in isolated rat hearts. Methods Fifty-six male SD rats, weighing 180-250 g, were anesthetized with intraperitoneal 20% urethane 1 g/kg and heparin 1 000 U/kg. Their hearts were excised and perfused in a Langendorff apparatus. Fifty-six isolated hearts were randomly divided into 7 groups ( n = 8 each) : St. Thomas cardioplegic solution group (group C) and St. Thomas cardioplegic solution containing 6 different concentrations of emulsified isoflurane groups (group E1-6 ). After 20 min equilibration, cardiac arrest was induced with St. Thomas cardioplegic solution 20 ml and St. Thomas cardioplegic solution containing 0.28, 0.56, 1.12, 1.68, 2.24 and 2.80 mmol/L emulsified isoflurane 20 ml at 4℃for 45 min followed by 60 min reperfusion in group C and E1-6 respectively. HR, left ventricular developed pressure (LVDP), left ventricular end-diastolic pressure (LVEDP) and + dp/dtmax were recorded at the end of 20 min equilibration, 20, 40 and 60 min of reperfusion. Coronary effluent 1.5 ml was collected for determination of LDH and SOD activity and the concentration of cTnI. At the end of 60 min reperfusion, the area of myocardial infarction was calculated. Results Compared with group C, HR, LVDP, + dp/dtmax and SOD activity were significantly higher, LVEDP, LDH activity and cTnI concentration lower, and the area of myocardial infarction lower in group E4, and HR, LVDP, + dp/dtmax and SOD activity were significantly lower, LVEDP, LDH activity and cTnI concentration higher, and the area of myocardial infarction higher in group E6 and E6 ( P < 0.05) , but there was no significant difference in the above indices between group E1-3 and group C ( P > 0.05) . HR, LVDP, + dp/dtmax and SOD activity were significantly lower, LVEDP, LDH activity and cTnI concentration higher, and the area of myocardial infarction higher in group E1-3-5-6 than in group E4 (P < 0.05 ). Conclusion St. Thomas cardioplegic solution containing 1.68 mmol/L emulsified isoflurane can attenuate myocardial ischemia-reperfusion injury in isolatede rat hearts.

Objective To investigate the changes of serum adiponectin (APN) levels in patients with essential hypertension (EH) and the correlation with carotid artery intima-media thickness (IMT).Methods Sixty patients with EH(EH group) and 30 healthy people (control group) were studied,the EH patients were divided into 3 subgroups with 20 cases each according to the standard of China guideline for hypertension prevention and control (2005).The serum APN level was detected by double antibody sandwich ABC enzyme-linked immunosorbent assay,the blood lipids levels [total cholesterol (TC),triglyeride (TG),low density lipoprotein-cholesterol (LDL-C) and highdensity lipoprotein-cholesterol (HDL-C)]were detected by automatic biochemical analyzer,and the carotid artery IMT was detected by color Doppler ultrasonography.Results The serum APN levels and carotid artery IMT in EH group and 1,2,3 subgroup were significant differences compared with those in control group [(3.94 ± 1.28),(5.25 ± 1.69),(4.01 ±1.27),(2.56 ± 0.87) mg/L vs.(7.63 ± 2.50) mg/L; (1.30 ± 0.42),(0.94 ± 0.30),(1.32 ± 0.44),(1.65 ±0.51)mm vs.(0.69 ± 0.22) mm,P ＜ 0.05].The comparison between two subgroups,along with elevated blood pressure levels,APN levels gradually decreased,and carotid artery IMT gradually increased (P ＜0.05).The serum TC,TG,LDL-C and HDL-C levels in EH group and 1,2,3 subgroup were significant differences compared with those in control group [TC:(6.53 ± 2.09),(5.14 ± 1.66),(6.59 ± 2.20),(7.86 ±2.42) mmol/L vs.(4.17 ± 1.32) mmool/L;TG:(2.15 ± 0.69),(1.72 ± 0.55),(2.07 ± 0.69),(2.65 ± 0.82)mmol/L vs.(1.38 ±0.44) mmol/L;LDL-C:(3.78 ± 1.21),(3.12 ± 1.01),(3.74 ± 1.25),(4.48 ± 1.38)mmol/L vs.(2.46 ±0.78) mmol/L;HDL-C:(0.96 ±0.31),(1.39 ±0.45),(0.85 ±0.28),(0.64 ±0.20)mmol/L vs.(1.69 ± 0.54) mmol/L,P ＜ 0.05].The comparison between two subgroups,along with elevated blood pressure levels,TC,TG and LDL-C levels gradually increased,and HDL-C gradually decreased (P ＜0.05).There was negative correlation between the serum APN level and carotid artery IMT (r =-0.435,P＜0.01),and there was correlation between the serum APN level and blood lipids levels (TC,TG,LDL-C and HDL-C) (P ＜ 0.01).Conclusions The APN plays an important role in the occurrence and development of EH,it is closely related to the carotid artery IMT thickening and lipid metabolism disorders.Increasing the lipid-lowering drugs may improve the efficacy of antihypertensive therapy in patients with resistant EH.

Objectives:To detect the relationship between cerebrovascular function and the disease term in type 2 diabetes. Methods:A total of 38 type 2 diabetes patients and 17 health control subjects entered the study. Patients were divided into two groups: those with long term diabetes and those with short term diabetes. Mean blood flow velocity in the middle cerebral artery(MCA),internal carotid artery(ICA), anterior cerebral artery(ACA),basilar artery(BA) and pulsatility index(PI) were measured with a transcranial Doppler probe and the breathlolding index(BHI) were calculated. Results:V MCA and V BA in the long term DM group was significantly greater than those in the short term group and the control group( P

BACKGROUND:Titanium ions have been proved to stimulate the secretion of bone remodeling-related factors from T lymphocytes;however, the effects of titanium ions on the early activation, intermediate activation, and cel cycle of T lymphocytes remain unclear. OBJECTIVE:To investigate the effects of titanium ions on the proliferation and activation of T lymphocytes in vitro. METHODS:Cel proliferation and cycle test:Jurkat E6-1 T lymphocytes in logarithmic phase were col ected and cultured in the medium containing 0 (control), 25 (low concentration), 50 (middle concentration), and 100μmol/L (high concentration) titanium ions for 24 hours to detect the cel relative proliferation rate and cel cycle. Cel activation trial:Jurkat E6-1 T lymphocytes were divided into two groups that were subdivided into four groups containing 0, 25, 50, and 100μmol/L titanium ions, respectively with or without phytohemagglutinin (PHA) pre-stimulation. The expressions of CD69 and CD25 were measured after cultured for 24 hours. RESULTS AND CONCLUSION:Titanium ions enhanced T lymphocytes proliferation in a concentration-dependent manner (P<0.05). Compared with the control group, the percentages of G0/G1 phase decreased and the proportions of cel s in S and G2/M phase increased significantly in the low, middle and high concentration groups (P<0.05). The proportion of G0/G1-phase cel s in the high concentration group was less and the proportion of G2/M phase cel s was higher than those in the middle and low concentration groups (P<0.05). With PHA pre-stimulation, the expression of CD69 in the high concentration group was higher than that in the middle and low concentration groups (P<0.05);whereas the difference of CD25 expression was not significant among four subgroups. Titanium ions promoted the expression of CD69 in a concentration-dependent manner (P<0.05), but there was no CD25 expression in each subgroup without PHA pre-stimulation. To conclude, titanium ions can significantly promote T lymphocyte proliferation and early activation in vitro, and moreover, induce S and G2/M phase arrest in T lymphocytes.

Objeetive To investigate the optimized concentration,effectiveness and histological change of Pingyangmycin by local injection of keloids for two weeks.Methods The appropriate concentration was analyzed,based on the Vancouver scar scale.48 eases of keloids were randomly divided into 4 groups with different concentrations of Pingyangmycin (1,0.5,0.25,and 0.125 mg/ml).Each case was iniected for five times at two weeks intervals,and then the statistical results (pair t test) and the histological changes were evaluated.Results Statistically,0.5 mg/ml group was more effective (P=0.0026),and this group had significant differences from the others (SNK test).The rate of the recurrence for one year was 12.00% in the whole effective cases.The keloid tissue after treatments,histologically,showed the thicker epidermis and larger papillary layer of the dermis,more inflammatory cells.Conclusions 0.5 mg/ml Pingyangmycin is the most appropriate concentration in this study and 0.25 mg/ml is the effective one.This treatment for keloid is convenient,safe,effective,low recrudescence and few side effects.

BACKGROUND: Following trauma caused by seawater, cells often exhibit special pathological changes because of the special physico-chemical properties of seawater.OBJECTIVE: To observe corneal histopathological changes and interleukin-6 level in aqueous humor of a rabbit model of penetrating corneal trauma combined with seawater immersion.METHODS: The rabbit eye models of penetrating corneal trauma caused by firecrackers were established in 16 adult healthy grey rabbits. A 3-mm whole-layer incision was made in the cornea. The right eyes served as experimental sides and the left eyes served as controls. Seawater was injected into the aqueous humor of the right eyes via the corneal incision. The eye surface was flushed with seawater for 30 minutes. Physiological saline was used for the left eyes. RESULTS AND CONCLUSION: Optical microscopy results showed that at 1, 2, 3 days after model establishment, corneal cells on the experimental side exhibited severe necrosis and abscission, obvious swelling of substantia propria layer complicated by cellular infiltration. At 1 and 2 days after model establishment, the pathological changes on the control side were the same as the experimental side, but they were mild, but at 3 and 5 days, they were obviously alleviated. At 1, 2, 3 days after model establishment, interleukin-6 level in aqueous humor was significantly higher on the experimental side than on the control side (P < 0.05). These findings suggest that the degree of injury on the experimental side was more severe than that on the control side, indicating that seawater may be an important causative factor of corneal injury.

Objective To investigate paclitaxel cross resistance and provide information for clinical therapy by establishing a paclitaxel resistant human lung adenocarcinoma cell line.Method A paclitaxel resistant human lung adenocarcinoma cell line named with SPC-A1/Taxol was developed by intermittent exposure to gradually increasing concentration of taxol.Resistant index was calculated from median inhibitory concentration(IC50)which was evaluated by MTT assay.Results SPC-A1/Taxol cell line displayed high resistance to taxotere,vinorelbine,vincristine and doxorubicin.It also displayed median or low resistance to camptothecins and podophyllotoxins.No cross resistance was observed to antitumor platinum and antimetabolite drugs and elemene emusion.Conclusion SPC-A1/Taxol cell line is a typical multidrug-resistant cell line in vitro.It could be useful for studing the cross resistance and direct clinical medication.
