Objective To investigate the method of the artificial lipofuscin preparation. Methods Extracting the hepatic mitochondrion of rat, we applied oxidation-reduction method to making and obtaining the artificial lipofuscin.The capability of artificial lipofuscin being digested by peritoneal macrophages of mice was examined. Results The artificial lipofuscin had positive reactions both to specific histochemical stain and FITC fluorescence label.Positive granules or fluorescence were present in cytoplasm of the macrophages and its distribution was similar to that of positive control.Conclusion The artificial lipofuscin had the same histochemical character and biological effect as natural lipofuscin, so it could be used as a substitute for anti-senescence research.

AIM:Vascular smooth muscle cell (SMC) proliferation and migration from the arterial wall media into the intima are believed to play a critical role in the pathogenesis of restenosis. Several studies have demonstrated that phosphothioate (PS) oligodeoxynucleotides targeted against genes involved in SMC proliferation inhibits in vitro SMC proliferation and migration. However, the therapeutic effect of antisense ODN on the individual who receives the treatment of delivery of the agent depends on the efficacy of this agent in great degree. We investigated the inhibition effect of a novel agent, insulin-antisense-c-myb-PS-ODN on SMC proliferation in vitro. METHODS:The rat aortic artery SMCs were cultured in Dulbecco's modified Eagel's medium. The passage 8 to 13 were used as the experiment. Cell surface receptor binding assay was quantified through counting gamma particles emitted from 125 I labeled insulin. SMC rapid proliferation was brought by stimulation of high concentration of fetal bovine serum (FBS). The novel agent of insulin conjugated to the antisense-c-myb-PS-ODN was obtained via incubation of both in condition of certain reagents, pH, temperature, and ion concentration. The characterization and purification of the agent was performed through HPLC. Inhibition of SMC proliferation was reflected by incorporation rate of trillium labeled thymidine deoxyribonucleotide.RESULTS:The binding efficacy of insulin to the receptor was remarkably increased in SMC cultured in supplement of 20% FBS. The inhibition effect of conjugator insulin-c-myb-antisense-PS-ODN was stronger than that of the simple c-myb-antisense-PS-ODN. The inhibition rate of conjugator and simple form on SMC proliferation were 48.34% and 29.54%, respectively. CONCLUSION:The binding efficacy and specificity of c-myb-antisense-PS-ODN to SMC may be enhanced by the insulin receptor mediation through the insulin-insulin receptor interaction. The insulin-receptor targeted method may be a potential and specific therapeutic pathway for restenosis.

Objective To develop a system for hand function evaluation and training based on virtual reality. Methods 5DT Data Glove 5 Ultra, Visual Studio 2010 were integrated as the development environment and DirectX 9.0 as components, and the system was developed based on the MFC programming framework. Results and Conclusion The system can assess the fingers function, recognise gestures and can be used as a 3D environment for virtual training, which may guide the patients to take the training actively.

Objective To observe the effect applicated of endoscopic sinus joint laryngoscope in laryngeal microsurgery.Methods 68 patients with laryngeal lesions were randomly divided into the multi-mirror combination group (34 cases) and the single laryngoscope group (34 cases).The multi-mirror combination group was taken with laryngeal microsurgery under endoscopic Joint laryngoscope.The single laryngoscope group was only taken with laryngeal microsurgery under laryngoscope.The efficacy and surgical situation of the two groups were compared.Results The total effective rate of the multi-mirror combination group was 97.06%,which was significantly higher than that of the single-laryngoscope group (85.30%) (x2 =4.031,P < 0.05).Compared with the case of surgery and complications and recurrence rate,the multi-mirror combination group was superior to the single laryngoscope group (all P < 0.05).Conclusion The endoscopic joint laryngoscope has the function of expanding the scope of the operative field and increasing the focus and clarity,and also has the advantages of small traumatic for patients,fewer complications,low recurrence rate,easy operation and high accuracy.

Objective [WT5”BZ] To evaluate the surgical treatment of insulinomas in the head and neck of the pancreas. [WT5”HZ]Methods [WT5”BZ] Data of 43 patients with insulinomas located in the head and neck of the pancreas during the past 16 years in PUMC Hospital were analyzed retrospectively.[WT5”HZ] Results [WT5”BZ] The average age of patients was 37 years old with an average preoperative history of 2 7 years. The preoperative accuracy of PTPC, DSA, B ultrasound, CT and MRI were 89 5%,72 5%,22 4%,25 3% and 66 7% respectively. The accuracy of intraoperative palpation was 97 8%. Enucleation of tumors was usually applied, and distal pancreatectomy or Roux en Y pancreaticojejunostomy were performed in 7 cases. The incidence of postoperative pancreatic leakage was 32 6%.[WT5”HZ] Conclusions [WT5”BZ] Selection of operation methods depends on the relationship of tumor with pancreatic duct and bile duct. Intraoperative monitoring of blood glucose is an essential mean to verify the complete resection of tumors. [WT5”HZ]

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.
