Treatment group serum AST,ALT, α-GST, GLDH contents and NF-κB, TNF-α, IL-6, IL-8 contents in liver tissue were lower than model group (t=5.128~32.325, P<0.05).Conclusion Alcohol feeding can cause liver damage, rubescens therapy can reduce liver injury, relieve inflammation.

BACKGROUND: Absorbable material is a hotspot in orthopedics, which is biodegradable, avoids fixation residues and second surgical trauma compared with the traditional internal fixation.OBJECTIVE: To investigate the clinical efficacy and safety of K-wires, screws and absorbable rods for the internal fixation of Mason II-III radial head fractures.METHODS: Totally 45 patients with Mason Ⅱ-Ⅲ radial head fractures were collected from January 2010 to December 2015 admited in Zhangjiagang First People's Hospital and Zhangjiagang Hospital of Traditional Chinese Medicine, and were then divided into three groups (n=15 per group), followed by implanted with K-wires (group A), screws (group B)and absorbable rods (group C), respectively. The baseline data, operation time, blood loss, healing time, Mayo and Broberg-Morrey scores were compared among groups.RESULTS AND CONCLUSION: (1) There were no significant differences in the baseline data, operation time, blood loss,and healing time among groups (P > 0.05). (2) The Mayo scores in the groups A, B, and C were (88.45±6.22),(92.37±5.60), and (90.82±6.58), respectively; the Broberg-Morrey scores in the groups A, B, and C group were ((90.82±6.83), (93.05±6.54), and (91.68±7.15), respectively; all above scores showed no significant differences among groups (P > 0.05). (4) The total incidence rate of complications in the groups A, B, and C was 20％ (2/15), 13％ (2/15),and 7％ (1/15) respectively, showing no significant difference among groups (P > 0.05). (4) These results indicate that the absorbable rods can obtain satisfactory treatment outcomes for Mason II-III radial head fractures, which is equivalent to the traditional internal fixation. Moreover, it can avoid secondary operation for removing internal fixators and the adverse impact of stress shielding, so it is recommended to be used in clinic.

ObjectiveTo investigate the correlationship between clinical and histopathological results of adrenocortical hyperplasia,adenoma and adenocarcinoma in the adrenocortical glomerular,fascicular and reticular zones. MethodsA total number of 167 702 surgical specimens were collected by the Department of pathology at the General Hospital of Tianjin Medical University from 1993 -2008.Of these,there were 631 adrenocortical specimens.Statistic analysis was done with Run test,t or t'test and x2 test on data in the aspects of proportion rate,mean age,sex proportion and relationship between clinical and pathological results of adrenocortical diseases.ResultsThe total number of adrenal diseases and adrenocortical diseases were 910 cases (0.54％) and 631 cases (0.38％),respectively.The number of adrenocortical glomerular,fascicular,reticular diseases were 310 cases (49.13％),319 cases (50.55％) and 2 cases (0.32％),respectively.The rate of adrenal diseases and adrenocortical diseases specimens did not change during the 16 year study period.The trend in proportion of hyperplasia,adenoma,adenocarcinoma in adrenocortical glomerular,fascicular and reticular zones did not change as well.The proportion pattern showed that there were more cases of adenoma than of hyperplasia and adenocarcinoma.The functional diseases of adrenocortical glomerular,fascicular and reticular zone (90.97％,79.00％,100.00％ ) were higher than nonfunctional diseases in the corresponding zones (9.03％,21.00％,0％ ) and both were higher in female patients.The mean age of nonfunctional patients with adenoma,glomerular zone adenocarcinoma and hyperplasia,adenoma of fascicular zone was higher than that in functional diseases.Interestingly,the mean age of glomerular zone adenocarcinoma patients (62.7 yrs) was higher than that in hyperplasia patients (47.8 yrs) and in adenoma patients (44.8 yrs).The mean and male diagnostic ages of adenocarcinoma of fascicular (44.3 yrs,50.0 yra) were higher than that in adenoma (44.0 yrs,49.1 yrs) and hyperplasia (41.5 yrs,40.9 yrs) respectively.But the female mean diagnostic age of fascicular adenocarcinoma (38.7 yrs) was lower than that in adenoma (42.4 yrs) and hyperplasia (41.9 yrs) respectively and the lowest average age was for nonfunctional adenocarcinoma (34.4 yrs).The diameters of the functional and nonfunctional adenocarcinoma were large (4.3 cm and 4.0 cm in glomerular zone,7.1 cm and 8.0 cm in fascicular zone).The carcinoma cells were in serious atyrpia,haemorrhage,necrosis and capsular or vascular infiltration.The rates of functional hyperplasia,adenoma with hypertension in Conn,Cushing or adrenogenital syndrome of adrenocortical glomerular,fascicular,reticular zone were higher than that without hypertension,but their tumor diameters were similar.The diameters of functional adenoma in glomerular or fascicularer ( 1.7 cm,2.3 cm ) were lower than that of nonfunctional adenoma (2.3 cm,2.4 cm ) and the diameters of glomerular tumors were smaller than that of fascicular tumors.Nonfunctional adenoma ( 2.5 cm,2.0 cm ) of glomerular or fascicular by check up finding were bigger than that of non-endocrine adenoma ( 2.5 cm,2.3cm).There were seven cases with adrenogenital syndrome (2 male cases,5 female cases ),among these,there were 4 fascicularer adenoma cases,1 adenocarcinoma case,1 network hyperplasia case and 1 adenoma case.ConclusionsGenetic abnormality plays an important role in pathogenesis of adrenocortical disease and environment had less influence.Radiological examinations (CT and MRI) of adrenocortical diseases are the first choice and have important roles in evaluating tumor characteristics.There is close relationship between clinical manifestation and pathology.However,the exact diagnosis of definite type of disease and nature of tumor needs to be made by pathologic examination.

Objective To establish VX2 hepatic carcinoma model in rabbits by implanting the tumor fragment into the liver through percutaneous puncture under ultrasound guidance and to observe its growing and metastatic characteristics, to determine the optimal time for interventional experiment study with the model. Methods Inoculation of VX2 carcinoma fragment was performed in 28 New Zealand white rabbits. PET/CT and ultrasonography (US) examinations were carried out in the second, third and forth week after the inoculation, and each time two tumor-bearing rabbits were sacrificed for pathologic study. Results The successful rate of model establishment was 89.28% (25/28). On PET or CT scans, single lesion in the liver was demonstrated in 25 rabbits. Two, three and four weeks after the inoculation, the maximum diameter of the tumor was (4.82±0.80) mm, (16.05±2.89) mm and (30.08±5.38) mm respectively, while the metastasis rates was 0% (0/25), 13.04% (3/23), 76.19% (16/21) respectively. No significant necrosis was found in the second week after inoculation, only tiny coagulation necrosis was revealed in the third week, and massive necrosis was seen in the forth week. Conclusion Percutaneous inoculation of the tumor fragment into the liver under ultrasonographic guidance is a simple method to establish VX2 hepatic carcinoma in rabbits with a high successful rate. The third week after inoculation is the suitable time for making interventional experiment study.

Objective To observe pathological features of peripheral vessel injury caused by ex-plosion shock wave so as to provide theoretical basis for emergency treatment, prevention and complication reduction of war extremity injuries. Methods A total of 18 rabbits were randomly divided into three groups (six rabbits in each group) and placed respectively at 1, 2 and 3 m away from the explosion cen-ter. The animal model with blast injury was made by using fluid dynamite that electrically exploded at 60 cm above the ground. The physical parameters of blast wave were recorded using pressure transducers (PCB, UAS). After explosion, the femoral arteries were examined grossly, histologically and immunohis-tochemically. Results The results showed that vascular endothelial cells were denudated, the spaces of contractile fiber cells increased and appeared puff, the vassular elastic fibers ruptured, flexed and de-formed visibly. Some parts of the vessel wall ruptured completely or partly, leading to bleeding. TUNEL staining and fluorescence microscope found large number of apoptotic cells in endothelium layer, smooth muscle layer and membrana adventitia layer of the blood vessels. Conclusion Explosion shock wave can result in severe large blood vessel injury, which should be paid much attention during treatment of ex-plosion shock injury.
