Objective To investigate the synergistic effect of calcium channel blocker on cyclosporine-induced gingival overgrowth (GO). Methods 130 renal transplant patients treated with cyclosporine were divided into group A (with calcium channel blocker) and group B (without calcium channel blocker). Demographic, pharmacologic and periodontal data were recorded. The prevalence and severity of GO were compared between the two groups. Three calcium channel blockers, including nifedipine, amlodipine and felodipine, were administered in the patients of group A. The relationships between these three calcium channel blockers and the prevalence of GO were analyzed. Results The patients receiving calcium channel blocker showed significantly higher prevalence of GO (44/73,60 % ) than those without calcium channel blocker (22/57, 39 %) (P＜0. 05). A higher proportion of mild GO (37 %) in group A was also observed than in group B (19 %, P＜0. 05). There were no significant differences in the proportions of moderate and/or severe GO between the two groups (P＞0. 05). Periodontal variables, including plaque index and papilla bleeding index, were significantly higher in GO patients than in those without GO in both two groups (P＜0. 05). In addition, the prevalence of GO in patients receiving nifedipine (77 %) was higher than in those receiving amlodipine (57 %) or felodipine (50 %). Conclusion The combination with calcium channel blocker is a risk factor of cyclosporine-induced GO and the use of nifedipine should be avoided for these at-risk patients.

Objective To establish standard liver volume formula of healthy Chinese and to explore if there is a correlation between changes of hepatic volume and hepatic functional reserve.Methods Two hundred and eighty healthy volunteers and 85 cirrhotics undergone serial abdominal H-CT scanning. The relation between normal liver volume measured by CT and body surface area(BSA) was studied by linear regression and correlation method, the standard liver volume formula was deduced. For cirrhotic patients, the change rate of liver volume was calculated and was compared with their Child class and postoperative complications.Results The mean normal hepatic volume for Chinese adults was (1?250?141)?cm 3. There is a positive correlation between estimated liver volume in vivo and body surface area[r=0.96, LV(cm 3)=613?BSA(cm 3)+162.8]. The mean liver volume (SD) for Child class A cirrhotics was (1?092?276)?cm 3, (868?163)?cm 3 for class B, and (652?76)?cm 3 for class C. Differences were observed among the three classes (P

Based on LPL model and clinical data collected, the correlation of ?/? factor with tissue volume irradiated has been derived. The data calculated by the new formula are coincidental with the results of clinical and animal experiments.

Objective To investigate the effects of ultrashortwave (USW) diathermy and electrical stimulation (ES) used in combination with nerve growth factor (NGF) in the treatment of experimental sciatic nerve injury.Methods Sixty adult Wistar rats were randomly divided into a normal control group, a model group, an NGF group,a physiotherapy group and a combined treatment group. A model of sciatic nerve injury was established in the latter four groups. Beginning on the 2nd day after the operation, no treatment was given in the model group, NGF was injected in the NGF group, diathermy and ES were administrated to rats in the physiotherapy group, and the combined treatment group was treated with USW diathermy, EW and NGF. Function, electrophysiology and morphology were evaluated at the 2nd, 7th, 14th and 30th days after the operation Results The average sciatic nerve function index (SFI), nerve conduction velocity (NCV) and nerve regeneration in the NGF, physiotherapy and combined treatment groups were significantly better than in the model group, with those in the combined treatment group improved to the greatest extent. At the 30th day there was no significant difference between the combined treatment group and the normal control group in terms of SFI, NCV, axon regeneration or myelin sheath thickness. The number of myelinated nerve fibers and the average axon diameter in the combined treatment group and normal control group were significantly higher than those in the model, NGF or physiotherapy group. Conclusions With NGF injection, additional application of USW diathermy and ES may significantly enhance the regeneration of the sciatic nerve and aid functional recovery after injury.

OBJECTIVE: To establish an HPLC method for the content determination of prostaglandin A1 and prostaglandin B1 in Alprostadil for injection.METHODS: The determination was performed on Alltech Alltima C18 column with mobile phase consisted of phosphate puffer(pH=6.3)-acetonitrile-methanol(70 ∶ 25 ∶ 5) at a flow rate of 1.5 mL? min-1.The detection wavelength was set at 196 nm.The column temperature was set at room temperature and the injection volume was 20 ?L.RESULTS: The prostaglandin A1 and prostaglandin B1 were well separated from main component and other impurities.The linear range of prostaglandin A1 and prostaglandin B1 were 0.175～19.00 ?g?mL-1(r=0.999 7) and 0.23～19.90 ?g?mL-1(r=0.999 2).The contents of prostaglandin A1 in 3 batches of samples were 4.7%,4.9% and 4.3%,and the contents of prostaglandin B1 in 3 batches of samples were 0.6%,0.8% and 0.5% respectively.CONCLUSIONS: This method is proved to be simple,specific and suitable for the content determination of related substances in Alprostadil for injection.

Objective To investigate the influence of hepatectomy combined with splenectomy on curative effect of primary hepatocellular carcinoma patients associated with hypersplenism.Methods Twenty three cases of primary hepatocellular carcinoma associated with hypersplenism were analyzed retrospectively and divided into hepatectomy combined with splenectomy group (n=10) and hepatectomy combined with ligation of splenic artery (n=13). Peripheral blood samples were collected 1 week before operation and 3 monthes after operation respectively. The levels of CD4, CD8, CD16, CD4/CD8, WBC and PLT in the blood were detected. Survival rate between the two groups was compared. Results There were not significant differences in the expressional levels of CD4, CD8, CD16, CD4/CD8,WBC and PLT before operation, bleeding quantity during the operation and rate of severe complications after operation in the two groups. The expressional levels of CD4, CD16, CD4/CD8, WBC and PLT of hepatectomy combined with splenectomy group were much higher in 3 months after operation than those in 1 week before operation and in hepatectomy combined with ligation of splenic artery group (P

[Summary] A 61-year-old female patient was diagnosed as ACTH independent Cushing′ syndrome, right adrenal adenoma, right facial infection. The situation was well controlled with antibacterial agents, abscess incision drainage and ketoconazole therapy. The patient received partial adrenolectomy of her right adrenal gland 16 months later. This case indicated that anti-adrenal agents could be a reasonable choice when the Cushing′syndrome patients were acompanied with severe infection.

BACKGROUND:Pancreatic stelate cels transforming growth factor β1/Smads signaling pathway activation is probably a main molecular mechanism of pancreatic fibrosis. If this pathway can be blocked, the progression of fibrosis of tissues with chronic pancreatitis wil be inhibited. OBJECTIVE:To study the inhibitory effect of colchicine on transforming growth factor β1/Smads pathway in chronic pancreatitis rat models. METHODS:Healthy male Sprague-Dawley rats were randomly divided into colchicines-treated group and chronic pancreatitis group. After successful establishment of rat models of chronic pancreatitis, the rats in the colchicines-treated group were intraperitonealy injected with colchicine 150 μg/kg daily. The rats in the chronic pancreatitis group were intraperitonealy injected with equal volume of physiological saline daily. Pancreatic tissues were colected after 3 months. Hematoxylin-eosin staining was used to observe histopathological changes of pancreatic tissue. Immunohistochemical staining was used to detect the expressions of transforming growth factor β1 in pancreatic tissue. Western blot assay was utilized to detect the expressions of P-Smad2, P-Smad3 and α-SMA protein in pancreatic stelate cels. RESULTS AND CONCLUSION: Hematoxylin-eosin staining results revealed that compared with the colchicines-treated group, glandular tissue had reduced, while fibrous connective tissue and inflammatory cels had increased obviously and replaced the pancreatic gland tissue in the chronic pancreatitis group. Immunohistochemical staining results demonstrated that the expression levels of transforming growth factor β1 and the index of positive cels were significantly lower in the colchicines-treated group than those in the chronic pancreatitis group (P < 0.05). Western blot assay results revealed that the results of P-Smad2/β-actin, P-Smad3/β-actin andα-SMA/β-actin in pancreatic stelate cels were significantly lower in the chronic pancreatitis group than those in the colchicines-treated group (P < 0.05). Results suggested that colchicine could inhibit the activity of transforming growth factor β1/Smads pathway and pancreatic tissue fibrosis in chronic pancreatitis rats. Therefore, colchicine can be used as a new candidate therapeutic scheme for chronic pancreatitis fibrosis.

BACKGROUND:Diabetic cystopathy is one of the most common chronic diabetic complications. The establishment of animal models of diabetic cystopathy wil provide experimental animal platform for relevant research.
OBJECTIVE:To establish a guinea pig model of diabetic cystopathy and to evaluate its urodynamic characteristics.
METHODS:Fifty short-hair Britain female guinea pigs were randomly divided into two groups, 42 as the experiment group and the other 8 as the control group. The experiment group was intraperitoneal y injected with streptozotocin to induce diabetes. The control group received injection of blank citric acid buffered solution. Diabetic guinea pigs were detected by urinary dynamics test at 9 and 12 weeks. Diabetic guinea pigs were further assigned into diabetic cystopathy subgroup and compensated subgroup. The urodynamic parameters of three groups were compared.
RESULTS AND CONCLUSION:Twenty of 42 guinea pigs were successful y induced diabetes by the injection of streptozotocin. At 9 weeks after the injection, bladder function compensation was present in six diabetic guinea pigs while bladder function was decompensated in another three diabetic guinea pigs. At 12 weeks, bladder function compensation was present in one diabetic guinea pig, while another eight guinea pigs were confirmed with diabetic cystopathy (88.89%). In the diabetic cystopathy subgroup, the residual urine volume was increased (0.72±0.08) mL, maximal detrusor pressure was decreased (0.63±0.05) kPa, maximum bladder capacity was increased (2.01±0.05) mL, and bladder compliance was increased (0.34±0.04) mL/kPa. There were significant differences compared with the compensated subgroup and the control group (P<0.001). Diabetic cystopathy occurs at 12 weeks after diabetic models are successful y established in guinea pigs, and urodynamic changes are mainly the increase of residual urine volume.
