Objective To study the influencing factors of retinal vessel caliber in type 2 diabetes mellitus and supply the elementary data for clinic. Methods Two hundred diabetic patients were involved in this study, and the vessel caliber was measured by fundus oculi color photo and computer-assisted imaging program. Biochemical indicator and blood pressure was examined and other document was achieved by questionaire. Results In type 2 diabetes mellitus, the retinal vein caliber had negative correlation with age and positive correlation with fasting blood glucose (FBG), glycosylated hemoglobin A1c (HbA1c) and the duration of diabetes mellitus(P < 0.01 ). The retinal arteriole caliber had negative correlation with age, blood pressure and the duration of diabetes mellitus (P < 0.01 or < 0.05 ). Conclusion The influencing factors of retinal vessel caliber in type 2 diabetes mellitus are age,FBG,HbA1c,blood pressure and the duration of diabetes mellitus.

Objective To observe the signs of retinal vessel diameter among different clinical characteristic groups such as sex,age,BMI,the duration of DM. Methods200 diabetic patients were selected.Using face to face questionnaire survey forms filled in the questionnaire in order to collect the general situation of all subjects selected.The diameters of vessels were measured using a computer-assisted imaging program. ResultsIn type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different sex.In type 2 diabetes mellitus,as age increased,both the retinal arteriolar diameters and the retinal veular diameters declined.In type 2 diabetes mellitus,there was no significant difference in the retinal arteriolar and veular diameters between the groups with different BMI.In type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.After storied in accordance with age,we can draw the sameConclusion . ConclusionIn type 2 diabetes mellitus,as the duration of DM increased,the retinal veular diameters dilated and the retinal arteriolar diameters declined.

Objective To assess the effect of Ambroxol combined with Naloxone on respiratory insufficiency on premature infants. Methods A total of 168 premature infants treated from 2006 to 2009 in our hospital were divided into two groups randomly. Additionally to the conventional treatment, Ambroxol (5 mg pertime) combined with Naloxone (0.1mg pertime) intravenously injected 2 to 3 times one day for 3 to 5 days in the treatment group(86 cases). The control group (82 cases) was treated by routine Aminophylline injection,3- 5 mg/kg pertime, 2 to 3 times one day. Respiratory rates, regulately or not,breathholding, cyanosis and apnea,mechanically ventilated time,time of oxygen inhaling, time of hospital stay and the overall response rate were measured. Results The overall response rate was 80% (69/86) in the treatment group and 56% (46/82)in the control group, with significant difference between the two groups ( P ＜ 0. 05 ). Mechanically ventilated time,time of oxygen inhaling and hospital stay in the treatment group was (110.5±45.1) hrs, (169.3±58.6) hrs and ( 12±3) days, which were all significantly lower than that in the control group ( 181.1±81.2) hrs, (236.6±87.8)hrs and (16±5)days,respectively(P＜0.01 or 0.05). Conclusion Ambroxol and Naloxobe additional to conventional treatment could improve the respiratory function in premature infants with respiratory insufficiency safely with less side effects. Moreover,breathing machine could be removed to some extent,which made it more applicable in primary hospitals.

Objective: To observe the preventive effect of taurine on alcoholic liver damage in rat.Methods: The model was induced by filling stomach with alcohol, and the treatment groups were given two different concentrations of taurine, and the control group was given 0.9%NS, then we measured the blood triglycerides (TG), and the pathological changes of liver quantitatively.Results: Two different le-vels of taurine can significantly decrease the level of TG and ameliorate the liver damage of rats (P0.05), and the 5% taurine group can also decrease the mean arterial pressure (P

Objective To evaluate the effect of dexmedetomidine on the expression of brain-derived neurotrophic factor (BDNF) during lidocaine-induced spinal neurotoxicity in rats.Methods Fifty-six male Sprague-Dawley rats,weighing 250-280 g,aged 2-3 months,were divided into 7 groups (n =8 each) using a random number table:sham operation group (group S),lidocaine group (group L),normal saline group (group NS),3 different doses of dexmedetomidine groups (D1,D2 and D3 groups),and oα2-adrenoceptor antagonist yohimbine group (group Y).An epidural catheter was placed at L5.6 interspace.Ten percent lidocaine 20 μl was injected intrathecally in all groups except group S.Dexmedetomidine 5,15 and 25 μg/kg were injected intraperitoneally at 30 min before lidocaine injection in D1,D2 and D3 groups,respectively.In group Y,yohimbine 1.0 mg/kg was injected intraperitoneally at 15 min before dexmedetomidine 25 μg/kg was injected.Before intrathecal administration and at 24,48 and 72 h after intrathecal administration (T1-4),the Basso,Beattie,Bresnahan (BBB) Locomotor Rating Scale was used,and the tail flick latency to a thermal nociceptive stimulus (TFL) was measured to assess the locomotor function.The rats were sacrificed after the last behavioral test,and the lumbar segments (L3-5) of the spinal cord were removed for pathological examination and for determination of BDNF expression and cell apoptosis.The apoptosis index was calculated.Results Compared with group S,the BBB score was significantly decreased at T2-4,the TFL was prolonged,the BDNF expression was up-regulated,and apoptosis index was increased in L,NS,D1,D2 and D3 groups (P＜0.05).Compared with group L,the BBB score was significantly increased at T2-4,the TFL was shortened,the BDNF expression was up-regulated,and apoptosis index was decreased in group D3 (P＜0.05),and no significant change was found in the parameters mentioned above in NS,D1,D2 and Y groups (P＞0.05).Compared with group D3,the BBB score was significantly decreased at T2 4,the TFL was prolonged,the BDNF expression was down-regulated,and apoptosis index was increased in group Y (P＜0.05).The pathological changes of the spinal cord were significantly attenuated in group D3 as compared with group L,and there was no significant difference in pathological changes of the spinal cord between group Y and group L.Conclusion The mechanism by which dexmedetomidine reduces lidocaine-induced spinal neurotoxicity may be related to up-regulation of BDNF expression,and the mechanism by which dexmedetomidine up-regulates BDNF expression is completely related to activation of α2-adrenoceptors in rats.

Objective To introduce ward calling system based on power line communication. Methods The system is de- signed based on SCM and spread spectrum communication chip. It adopts principal and subordinate structure, transmits data on low-voltage power line. The spread spectrum communication chip is SC1128, which is specially designed for Chi- nese low power line.
