?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

Objectives To investigate the characteristics of neural invasion of pancreatic cancer as well as its relationship with other clinicopathological factors. Methods The neural invasion situation of 491 cases of ductal adenocarcinoma and other 22 pancreatic malignancies, 41 cases of benign tumor of pancreas and 21 cases of chronic pancreatitis was observed under light microscope, and its relationship with other clinicopathological factors was analyzed. Results The rate of neural invasion in ductal adenocarcinoma (74%) was much higher than in other types of pancreatic neoplasm (23% ,P ＜ 0.01). Pancreatic ductal adenocarcinoma cell often invaded through peripheral nerve membrane into inner nerve fiber bundle, sometimes even invaded the whole cross-sectional nerve fiber. But neural invasion was not associated with differentiation of the tumor. The occurrence of chronic inflammation in the para-tumoral pancreas (52%) was also higher than that in other types of malignant (14%) or benign lesions (15% ,P ＜0.01). Lymphocytes neural invasion rate in pancreatic ductal adenocarcinoma was 65%, which were significantly higher than those in other types of malignant (36%) or benign lesions (22%, P ＜ 0.01). Neural invasion rate in pancreatic ductal adenocarcinoma was associated with paratumoral chronic pancreatic inflammation and lymphocytes neural invasion, but not with lymph node metastasis. Conclusions Neural invasion was characteristic biological behavior in pancreatic ductal adenocarcinoma.

Objective To explore the effect of using pedicle skin flaps for treatment of skin and soft tissue defects.Methods From January 2004 to September 2010,87 patients with skin and soft tissue injury which had been treated by using pedicle skin flaps without vessel anastomosis were retrospectively analyzed,including 61 males and 26 females with an average age of 40 years (range,14-61).The pedicle skin flaps selected were known vessel skin flaps or unknown vessel random skin flaps.The reconstruction treatment increased multiple selections of skin flaps for patients.Skin and soft tissue defects were located at the hand in 21 cases,at the lower extremities in 66.The kinds of skin flaps included adjacent transposition flaps in 50 cases,distal skin flaps in 37.The areas of the skin flaps were 2.0 cm×1.5 cm-18 cm×12 cm.Donor sites were as follows:lower leg in 61 cases,abdomen in 18,and hand in 8.Results Three patients appeared skin flaps hematoma after operation,which were removed immediately with no effect on flaps survival.Pedicle skin flap was compressed due to unstable fixation in 1 case,which made distal flap tissue necrosis approximately 2 cm in width.After dressing change for 6 weeks,the flaps got survival.Thirty seven patients underwent the second stage operation for breaking the perdicle 3 weeks after the first operation.All 87 patients were obtained follow-up for an average of 13 months (range,3-60).The total of 90.80％ patients treated with pedicle skin flaps were satisfied with the results.Conclusion Pedicle skin flap surgery can be performed more easily with less limitations of surgical designs.The survival rate of the flap is high,and the treatment of pedicle skin flaps could be well applied for soft tissue defects.

Objective:To explore the way to separate and culture eutopic and ectopic endometrial glandular cells and their stromal cells,providing an in vitro cell model of endometriosis for study of its mechanism. Methods:Digestion,filtration and sedimentation were used to isolate and culture the eutopic and ectopic endometrial glandular cells and their stromal cells. The estrogen level was imatated to study the way of promoting cell growth. Morphological characters of eutopic and ectopic endometrial cells were examined using optical microscope. Results:The success rate of separation and culture of normal control endometrial glandular cells and its stromal cells was 91.7%(11/12);of eutopic endometrial glandular cells and its stromal cells of endometriosis was 93.8%(15/16);of etopic endometrial glandular cells and its stromal cells of endometriosis was 75.0%(12/16) . Conclusion:The cultured eutopic and ectopic endometrial cells is more like human body feature than the endometriosis model of animals. So the isolation and culture of eutopic and ectopic endometrial glandular cells and their stromal cells may serve as an in vitro experimental model.
