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

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.

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

Objective To investigate whether epithelial-mesenchymal transition (EMT)is involved in the anti-invasion and anti-metastasis effects of curcumin on MDA-MB-2 3 1 breast cancer cell line and further analyze the underlying mechanisms.Methods MTT method was used to detect the anti-proliferative effect of curcumin on MDA-MB-2 3 1 cell line induced by lipopolysaccharide (LPS).The morphological changes were determined by optical and transmission electron microscopy,respectively.The expressions of Vimentin,E-cadherin,NF-κB and Snail were analyzed using RT-PCR and Western blotting.Results Curcumin could inhibit the occurrence of LPS-induced EMT of MDA-MB-2 3 1 breast cancer cell line, decrease the expression of LPS-induced EMT marker Vimentin and increase the expression of E-cadherin, resulting in the inhibition of in vitro cell motility and invasiveness.These actions were mediated by inactivating NF-κB-Snail signaling pathways.Conclusion Our data provide a new perspective of the anti-invasion mechanism of curcumin,indicating that the effect is in part due to its ability to inhibit the EMT process.

BACKGROUND:Studies have shown that arthroscopic al-inside technology for meniscus repair has achieved good outcomes, and arthroscopic suture combined with sodium hyaluronate has an important role in the cartilage repair. OBJECTIVE:To observe the therapeutic effect of arthroscopic al-inside suture repair combined with sodium hyaluronate injection in the repair of discoid meniscus tears. METHODS:Twenty-two patients with discoid meniscus injury were subjected to arthroscopic al-inside suture repair combined with sodium hyaluronate injection. Al cases were confirmed to have attached edge relaxation or longitudinal crack in operation. After repair, effective rehabilitation training was done. RESULTS AND CONCLUSION:The operations for the 22 cases were al successful and there was no complication. Al patients were fol owed up for over 18 months. According to Ikenchi’s method (Lysholm knee score criterion), 11 cases were rated excel ent, 8 were rated good, and 3 were rated fair, with an excel ent/good rate of 86.36%. It is demonstrated that the al-inside suture repair under the guide of arthroscopy in discoid meniscus cases can remain the most appropriate anatomical structure of the meniscus that can play an effective function, and has the advantage of minimal invasion. Arthroscopic al-inside suture repair combined with intra-articular injection of sodium hyaluronate and standard rehabilitation training result in a lower complication rate and effectively promotes the meniscus repair.
