Objective To observe curative effect of sodium ozagrel combined with cobamamide and pancreatic kininogenase in patients with diabetic peripheral neuropathy (DNP). Methods Seventy-two diabetes patients with DNP in our hospital from September, 2008 to September, 2010 were randomly divided into observation group and control group. All patients were treated with cobamamide by intramuscular injection and pancreatic kininogenase taken orally. In the observation group sodium ozagrel injection were added to the treatment used in the control group. Results After one course of treatment, the total effective rate in the observation group was 91. 7% (31/36),which was better than the control group (63. 9% ,23/36) (x =7. 6, P<0. 05). Motor nerve conduction velocity of median nerve before and after treatment was (42.9 ± 1.9)m/s and(45. 9 ± 3. 0) m/s in the observation group, and (42. 2 ± 1. 7) m/s and (43. 1 ± 2. 1) m/s in the control group. Motor nerve conduction velocity of peroneal nerve before and after treatment was (34. 9 ± 3. 9) m/s and (46. 1 ±3.0)m/s in the observation group, ,and (35. 6 ±3.4)m/s and(36. 8 ±2. 5)m/s in the control group;Sensory nerve conduction velocity of median nerve was (41.2 ±3.2) m/s and (48. 5 ±4.0) m/s in the observation group,and (41. 5 ±3. 8)m/s and(42.4 ±3. 6) m/s in the control group, sensory nerve conduction velocity of peroneal nerve was(35.4 ±3. 4) m/s and(44. 8 ± 3. 2) m/s in the observation group, and (35. 9 ± 4.4) m/s and(37. 6 ± 3. 3) m/s in the control group. The difference of nerve conduction velocity before and after treatment in the observation group reached the statistical significance(P<0. 05), whereas not significant in the control group (P > 0. 05). After treatment, the nerve conduction velocity in the observation group significant better than those in the control group (P < 0. 05). Conclusion The treatments of sodium ozagrel combined with cobamamide and pancreatic kininogenase in diabetic peripheral neuropathy is safe and effective.

A new modification of Merril's silver staining of proteins in sodium dodecylsulfate polyacrylamide gels is introduced.The use of a prolonged period step after fixation and adjusting of oxidant incubation time considerably decrease the background, therefore increase the sensitivity. The detection limit is fivefold lower than original method.

Objective To observe the effect of ganglioside GM3 on the proliferation and cell cycle of multiple myeloma (MM) cell line U266. Methods The experimental groups were treated with 20, 40, 80, 160μmol/L GM3, while the control group was not given GM3. The growth inhibition effect of GM3 on U266 cells after 48 hours were measured by using methyl thiazolyl tetrazolium (MTT) method. The cell cycle was tested by flow cytometry with PI labeling. Results The results indicated that the GM3 displayed anti-proliferative effects on U266 cells in a dose-dependent manner. The cell inhibition rates were (13±4) %, (26± 4) %, (47 ±6) %, (55 ±10) % in different dose of GM3 (20, 40, 80, 160 μmol/L), respectively. There was a difference between the experimental group and the control group (F= 93.063, P< 0.05). At the same time, the cell cycle analysis results showed that the U266 cell ratio in S phase was increased from (22.6 ±3.7) % to (71.5±3.8) %(P<0.01) and in G2/M phase was decreased from (42.6±2.5) %to (0.8±0.6) %(P<0.05) while in G0/G1 phase was not significantly changed. Conclusion GM3 can inhibit the proliferation of MM cell line U266 by blocking them in the S phase.

Enamel pearl is an ectopic enamel, which usually occurs in the root bifurcate or approaching enamel-cementum site of the first maxillary molar. A case of multiple enamel pearls on the left maxillary third molar is reported in this paper, and relevant literature was reviewed.

Peripherally inserted central catheter (PICC) has become internationally widespread in various healthcare settings (hospital, clinics ,homecare, et al), mainly used for administration of chemotherapy drugs, hypertonic parenteral nutrition solution and infusion therapy in two extreme age patients (neonates, especially in premature infants;elderly), which provides necessary vascular access for medium to longer term transfusion therapy. The risks of complications related with PICC are still existed, and PICC site with impaired skin integrity is prevalent, but described by only paucity of literature. International evidence-based guidelines provide little strategy. Our study was to review PICC site with skin injury in order to better understand the etiology, evolution and familiar with the international nursing dynamics, and identify directions for future research in this field, promote to overcome the nursing conundrum, and provide a basis for construction of guidelines for the skin management of PICC.

OBJECTIVE:To introduce the research progress of biliary tract prosthesis,to analyze the reason of complication following stent implantation,and to explore the biocompatibility of various biliary tracts and host. METHODS:We retrieved Medline database (1989/2009) and CNKI (1989/2009) using the computer. According to inclusion and exclusion criteria,the literatures were screened by the first author,and the data were collected,and the quality was evaluated. We described and arranged the treatment progress of biliary tract prosthesis implantation,complication of stent implantation and biocompatibility of biliary tract prosthesis to investigate treatment state,complication and biocompatibility of the biliary tract prosthesis. RESULTS:The literatures were summarized. The bilitary tract prosthesis contains plastic stent,mental stent,silica gel tract stent and degradable polylactic acid stent. The complications of stent implantation included transudation,hemorrhage,perforation and stenosis. Among various stents,the biocompatibility of plastic stent was poor,easy to be blocked,but the price was low,and easy to be taken out. The diameter of mental stent following distension could reach 7-10 mm,with long unobstructed time,but the price was higher compared with the plastic stent. The biocompatibility of silica gel tract stent was good. The silica gel tract had strong decay resistance and pliable texture,which could extend tumor excision range and elevate curative effects. Moreover,complications did not occur such as infection and stenosis of the biliary tract. Biocompatibility of nickel-titanium alloy biliary ducts was significantly better than the stent products,without complications. With the exception of price factor,the biocompatibility of degradable polylactic acid stent was the best,but further studies were needed to observe and study the formation of biliary sludge,stent displacement and blockage,stent degradation products. CONCLUSION:Biliary tract prosthesis implantation can be an important treatment method for stenosis of biliary tract. During treatment,enough preparation is needed prior to implantation according to various clinical symptoms to select suitable stent type. Indications are followed strictly to avoid the occurrence of complications. The biocompatibility of silica gel stent and Ni-Ti alloy stent is good,but the biocompatibility of other stents should be enhanced.

Objective To evaluate the NuMED covered CP stent for the treatment of adult aortic coarctation.Methods 6 patients with coarctation of the aorta received covered CP stent implantation.There were 4 males and 2 females cases with mean age of (20.13±5.16) years old.The size of the covered CP stents and balloons were determined by preoperative aortic CTA assessment.Stent implantation was per formed through femoral approach and the puncture site was sealed by vascular closure device after the operation.Results All the NuMED covered CP stents were implanted successfully.The pressure gradient dropped from (59.32±15.78) mmHg to (10.83±3.66) mmHg (P<0.001) after stenting.The diameter of the coarcation at the narrowest point increased from preoperative (5.1±1.2) mm to (19.7±2.4) mm after stenting (P<0.001).In 2 cases with PDA, the shunting disappeared spontaneously after operation with normalized of lower limb blood pressure.All the patients were followed up clinically for 12-36 months and all of them reported improvement in clinical symptoms post operation.Follow up Doppler echo or aorta CTA examinations at 3 months showed no restenosis.No mortality recorded during follow up.Conclusions NuMED covered CP stent for the treatment of aortic coarctation in adults showed satispactony short term outcome.Its long term outcome still requires further in vestigation.
