Objective To investigate the dosage and safety of insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs for the treatment of hyperglycemia in elderly hip fracture.Methods Patients with hip fracture and hyperglycemia who required insulin pump therapy were divided into 2 groups according to age:elderly group (patients aged over 65 years,n=42) and non-elderly group (patients aged under 65 years,n=43).All patients were treated with insulin aspart in continuous subcutaneous insulin infusion plus oral antidiabetic drugs combined with diet therapy.Dosages of aspart insulin and adverse effects were compared between the two groups.Results There were no significant differences in basic aspart dosage and additional premeal dosage between elderly and non-elderly groups [(0.29±0.09) IU/kg vs.(0.30±0.07) IU /kg,(0.27±0.09) IU/kg vs.(0.27±0.07) IU/kg,both P＞0.05].The incidences of hypoglycemia with and without symptoms in elderly versus non-elderly groups were 4.8％ vs.4.7％ and 14.3％ vs.18.6％,which had no significant differences between the two groups (P＞0.05).Hypoglycemia accompanied by consciousness disorders,allergy,nonhealing and slow healing wounds were not found in the two groups.The ratio of oral antidiabetic drugs including metformin,glimepiride,and glycosidase inhibitor had no differences between the two groups.Conclusions Aspart insulin in continuous subcutaneous insulin infusion is effective and safe in the treatment of acute severe hyperglycemia in elderly patients with hip fractures when combined with diet therapy and oral antidiabetic drugs.

Objective To identify the isolated rat bone marrow derived mesenchymal stem cells(MSCs),and evaluate the efficiency of adenoviral vector expressing human urokinase type plasminogen activator(uPA) in transfection of rat MSCs and its effect on proliferation of MSCs. Methods MSCs were isolated and purified by pasted wall purification,and were identified by immunicytochemistry.The transfection efficiency of uPA was detected by fluorescent microscopy,the expression of uPA in MSCs was detected by Western blotting,and the proliferation of MSCs was evaluated by MTT. Results The harvested MSCs exhibited the typical appearance of MSCs,and it was revealed by immunohistochemistry that the expression of MSCs markers CD29 and CD90 was positive,while that of CD34 and CD45 was negative.A tendency of increase in expression of green fluorescent protein(GFP) was observed with increase of multiplicity of infection(MOI).After transfection with AduPA for 72 h,the transfection efficiency reached(94.0?1.5)% at MOI of 80,and positive GFP cells could still be observed even after 7 d.The transfected uPA had no effect on the proliferation of MSCs. Conclusion MSCs are favourable genetic vectors to express uPA,and can be used for treatment of liver fibrosis.

OBJECTIVETo investigate the relationship between hormone sensitive lipase (HSL) gene polymorphism and aerobic endurance.

METHODSThe (CA)n repeats polymorphism genotypes in HSL intro 6 of 123 outstanding long distance runners and 127 controls of Han nationality in northern China were analyzed by PCR and Fluorescence labeled STR-genescan. Repeat polymorphisms were grouped according to segmentation point and alleles were divided into long or short chains. Chi-square test was used to analyze the frequency difference of allelic and genotypic between athlete and control groups.

RESULTS(CA) n repeats polymorphism in HSL gene was total of 9 different repeat number of alleles, which composed of 25 different genotypes. The chi-square test result showed that when compared short and long chain alleles split by 4, there was a significant difference (P <0.05) of genotype distribution in 5/10 km group compared with control. Compared the rest groups with control, there was no significant difference.

CONCLUSIONCompared short and long chain alleles split by 4, the LL genotype of (CA)n of HSL was associated with aerobic endurance and it might be a molecular marker of elite 5/10 km long distance runners.

ObjectiveTo observe the subcutaneous and intraperitoneal insulin injection's effect of the level of oxygen free radicals of type 2 diabetes model.MethodsC57BL/6J mice were chosen as normal control group (C group,n=9).KK mice were randomly divided into intraperitoneal injection of insulin group (i.p.group,n=9),the subcutaneous insulin group (s.c.group,n=9) and untreated group (U group,n =9).The i.p.group and the s.c.groups were given certain amount of insulin (insulin injecta and protamine insulin injecta by volume ratio of 2:1 mixture)for one month,maintained the GLU at normal levels (6±1.5) mmol/L.SOD,GSH-PX activity and MDA content of serum,liver,kidney and heart in each group were detected.Results The liver,kidney,heart and serum's SOD and GSH-PX activity significantly reduced and MDA content significantly increased in the U group.Both kinds of delivery methods could increase serum SOD and GSH-PX activity and reduce the content of MDA to the normal control group level,but the intraperitoneal injection had stronger effect.Two kinds of delivery methods could both reduce the MDA content of liver,and had almost the same effect; but the subcutaneous injection group had better effect on increasing the liver's SOD activity,and the intraperitoneal injection had better effect on increasing liver's GSH-PX activity.Intraperitoneal injection had better effect on reducing kidney' s MDA content and increased SOD activity.Two kinds of delivery methods had the same effect on reducing the heart's MDA content.Conclusion The two delivery methods can both make the MDA levels of KK mice in serum,heart,liver and kidney fall to as normal as that of control group,but the two delivery methods have different ways of improving the antioxidant capacity in different organs.Intraperitoneal injection can reduce MDA content in serum and kidney better.

Objective To evaluate the role and technical advantages of CT in 125Ⅰseed implantation in the treatment of tumors. Methods CT-guided 125Ⅰ seed implantation in 45 cases of cancer patients treated 57 times in 51 lesions,CT were used to evaluate the progress of lesions after 125Ⅰ seed implantation 1,2,6 months. Results All procedures were once successful and the total effective rate was 74.5% without any serious complications. Fifty CT examinations immediately after implantation showed satisfactorily seeds distribution but seven cases less satisfactorily that include particles overlap,the location is too close to the lesion edge,the larger the radiation cold spots,etc. Follow-up CT reexamination in 1,2 and 6 months demonstrated that CT examinations showed satisfactorily seeds distribution but accurate seeds number,which could be solved by combined with MPR images and the positioning piece. Conclusions CT-guided 125Ⅰ seed implantation treatment of tumors was a safe,reliable and effective minimally invasive treatment. CT in the preoperative treatment of seed implants planning,precise intraoperative guidance,quality assurance and efficacy of postoperative assessment had a greater role and application advantages.

Objective: To evaluate the effect of catheter ablation (CA) by endpoint of left atrium (AF)- pulmonary vein (PV) with bi-directional electrical isolation in treating the patients with paroxysmal atrial fibrillation (PAF) with remote electro-cardio graphic monitoring.
Methods: A total of 82 AF patients received radio frequency catheter ablation (RFCA) in our hospital and 76 PAF patients were observed. Based on circumferential pulmonary vein isolation (CPVI) judgment, the PAF patients were divided into 2 groups: Bi-directional block (BDB) group,n=20 and Entrance block (EB) group,n=56. The post-operative rhythm was followed-up by remote electro-cardio graphic monitoring and the clinical efifcacy of CA was prospectively observed.
Results:①All 76 patients finished CA, 1 patient died in EB group at 4 days after operation for pulmonary embolism, the rest 75 patients were followed-up for (31±19) months. The overall success rates of single ablation procedure at 3 months and 6 months after operation were 85.33% and 77.33%; in BDB group were 95.00% and 85.00%, in EB group were 81.82% and 74.55% respectively, the result was similar between 2 groups,P>0.05.②The overall occurrence rates of arrhythmia at 1 week and 3 months after operation were 35.53% and 17.33%; in BDB group were 15.00% and 5.00%, in EB group were 42.86% and 21.82% respectively, the differences between 2 groups were at P=0.049 andP>0.05.③Remote electro-cardio graphic monitoring recorded the patients with asymptomatic atrial arrhythmia at 1 week and 3 months after operation were at 22.22% and 23.08% respectively.
Conclusion:①Compared with EB group, BDB group had obviously lower occurrence rate of arrhythmia at short term after CA.②The overall success rate of single ablation procedure was similar between 2 groups which might be because less patients were studied.③Remote electro-cardio graphic monitoring has certain advantage for evaluating the occurrence of atrial arrhythmia after operation.

ObjectiveTo investigate bone marrow mesenchymal stem cells(BMSC) express brain derived neurotrophic factor(BDNF) and nerve growth factor(NGF) and their protective effect for neural stem cells (NSCs).MethodsBMSC were obtained from rat tibiae and femurs and centrifuged with Ficoll. The passage 3 cells were chosen to make immunocytochemical stain for CD44, CD71 and CD45. The expression of BDNF and NGF was detected in BMSC with RT-PCR, as well as in the media with ELISA. The media that cultured BMSC were collected as BMSC condition media. NSCs were obtained from cerebral cortex of new-born rat and cultured in vitro. After different ratio of BMSC condition midia were added, NSCs were induced to apoptosis with heat-shock, then NSCs were dyed with Annexin V-FITC/PI apoptosis kit and apoptosis rates were tested with flow cytometry. ResultsBMSC were CD44(+), CD45(-), CD71(+) and expressed BDNF and NGF mRNA. BDNF and NGF could be tested in the media of cultured BMSC and increase with cultured time. BMSC condition media could reduce the ratio of heat-induced apoptosis of NSCs, and more BMSC condition media showed better effect. ConclusionBMSC can express neurotrophic factores and protect neural stem cells from heat-induced apoptosis.

OBJECTIVEThis paper analyzed the epidemiological characteristics of rubella in Shanghai from 1990 to 2006.

METHODSDescriptive epidemiological study was applied to analyze the cases from infectious diseases reported system on rubella during 1990-2006 in Shanghai. Excel was used for data analysis.

RESULTSThe reported rubella incidence rate in Shanghai was 0.15-451.57 per 100,000 during the period from 1990 to 2006. A rubella epidemic happened in 1993, with the number of reported cases as 58,104. The year 1998 was the low year on rubella with only 19 reported cases. In the years without rubella vaccine (RV), that was, from 1990 to 1994, the annual reported incidence rate of rubella was 93 per 100,000, and there was a distinct characteristic of seasonal difference, with peak in march through June each year. Rubella cases mostly affected children aged 5-9 and adolescent of 10-14 years old. Since the wide use of RV in Shanghai since 1995, RV and measles, mumps, rubella (MMR) had been widely accepted by parents. The vaccination rate of MMR reached up to 85 percent. The incidence of rubella was descending as year went by. The annual reported cases were less than 100 since then (with exception in the year 1995). Local outbreaks were further reduced and the age group structure had also changed since the adoption of RV. Patients with RV fallen into the age group of 0-4 were increasing quickly, accounting for 21.00% percent of all the patients and the age become older. 31.62% of the patients fell into 20 years of age and above. During 1995-2006, the incidence rates of rubella in age 25-29 and 30-34 were both much higher than that in the year without vaccine.

CONCLUSIONThe trend of older age among patients wilt Rubella increased the risk on fertile woman and geting congenital rebella syndrome.

OBJECTIVETo explore the efficacy differences in early intervention of different acupuncture and moxibustion methods on gastrocnemius fatigue in rats induced by electrical stimulation.

METHODSFifty male SD rats were randomly divided into a control group, a model group, a hand acupuncture group, an electroacupuncture group and a moxibustion group, 10 rats in each group. Electrical stimulation of the sciatic nerve was given in the control group and gastrocnemius fatigue test was induced by electrical stimulation of the sciatic nerve in the model group after anesthesia without other treatment, but just take 6 times interval stimulation in the control group. The hand acupuncture group, the electroacupuncture group and the moxibustion group were treated with the corresponding acupoints stimulation method respectively for 20 min before gastrocnemius fatigue test, and Dazhui (GV 14) and Zusanli (ST 36) were selected. Immediately after gastrocnemius fatigue test, three or four gastrocnemius tissues at the same site on the right side were quickly taken for making specimen for transmission electron microscope (TEM). The changes of skeletal muscle ultrastructure of myofibrils, mitochondria, sarcoplasmic reticulum, glycogen particles were observed under TEM.

RESULTS(1) Muscle fibers disorder, partial mitochondrial vacuolization and glycogen particles smaller were shown in the model group. (2) No abnormalities were shown in the hand acupuncture group and the moxibustion group with mitochondrial morphology and number, which better than that in the model group, and glycogen particles increased. (3) Abnormal changes in morphology were shown in the electroacupuncture group with part of the muscle fibers derangement, Z line malalignment and a few mitochondria vacuolization.

CONCLUSIONHand acupuncture, electroacupuncture and moxibustion have the different effects on ultrastructure of gastrocoemius in rats. Acupuncture and moxibustion have shown good effects on the prevention and treatment of exercise-induced skeletal muscle cell and organelle damage and delaying exercise-induced fatigue.
