Methods We performed 2 h,4 h planar and 4 h tomogr aphy fusion imaging after injection of HL91 on 42 patients with high probability of pulmonary cancer. Tumor-to-normal tissue background (T/N) ratios were meas ured for all scans. Results T/N ratios at 2 h,4 h planar and 4 h transectional imaging in malignant group were 1.50? 0.17 ,1.71?0.22 and 2.72?0.75, respectively; while in benign group, they were 1.21?0.10,1.25 ?0.22 and 1.49?0.36, respectively. 4 h delay T/N ratios in malignant group we re obviously higher than 2 h ( P 0.05). There were no remarkable differences of T/N ra tios in different phases and histological types of lung carcinoma. Using maligna nt transection ratio ( -1s ) as diagnostic threshold, the sensitivity , specificity and accuracy were 84.85% , 88.89% and 85.71% , respectiv ely. Using transection ratio( +1s ) of benign group as diagnostic th reshold , the sensitivity, specificity and accuracy were 90.91%, 88.89% and 95.2 4%,respectively. Conclusion The results indicate that as a tumor positive imaging agent 99 Tc m-HL91 is useful in diagosising pulmon ary neoplasms.

Objective To certify whether 99mTc-HL91 can be trapped in ischemic myocardium prominently for clinical imaging. Methods The model of myocardial ischemia in rabbits was prepared and the distribution of 99mTc-HL91 was observed. The distribution of 99mTc-HL91 in the whole body was also observed. Results The myocardium of the left ventricle supplied by LCX was ischemic according to the change of electrical physiology and the results of NBT dying. The radioactivity in the myocardium of left ventricle supplied by LCX was higher than that supplied by LAD. LCX/LAD: 120 min, 2.57; 180 min, 3.45. 99mTc-HL91 was mostly distributed in the liver and kidney, next, the stomach and intestine. It was excreted through urination and defecation. There was little radioactivity in the heart and lungs and it eliminated quickly. 99mTc-HL91 was eliminated quickly from blood, too. Conclusion Ischemic myocardium can trap 99mTc-HL91 more significantly and relatively prominently at 180 minutes of post-injection. 99mTc-HL91 can be used in myocardial hypoxia imaging.

Osteoarthritis is a common articular cartilage degenerative disease and the main cause is mechanical instability. The mechanical instability can reduce the number of chondrocytes and destroy extracellular matrix through direct injury, inducing cell apoptosis, and stimulating the production of inflammatory factors, leading to decrease of matrix typeⅡ collagen and proteoglycan and degeneration of cartilage. Long-term cartilage degeneration can result in osteoarthritis. Therefore, understanding how mechanical instability leads to the incidence of osteoarthritis can better improve the course of osteoarthritis from the perspective of mechanics.

We compare the results of two subcutaneous insulin regimens in type 2 diabetic patients with fractures during the perioperative period. In group Ⅰ 162 patients received regular insulin three times+ NPH insulin bedtime protocol; in group Ⅱ 72 patients received regular insulin three times + NPH insulin twice protocol. The difference of the time achieving satisfactory level of blood glucose (BG) and associated factors were analyzed, and the related complications were observed. The average time achieving satisfactory BG level was (9.1±3. 3) days and (7.0±2.6) days for group Ⅰ and Ⅱ respectively (P <0.05). There were no statistical differences in hypoglycemia, infection and thrombosis between two groups. Binary logistics regression showed that the time of achieving desired BG level was associated with blood glucose(BG) and the proportion of the regular insulin and the NPH. The results indicate that five times insulin injection method can shorten the time of achieving desired BG level and may be benefit to diabetic patients with fracture.

We explored the status of Bartonella infection in rodents and the sequence characteristics of Bartonella in Fujian Province.Rodents in Fujian Province were captured by the night trapping method during 2014-2016.Information of the captured rodents on capturing dates and geographic locations,species,gender and ages were recorded.Heart blood samples were collected,from which the fragments of ghA gene and16S-23S rRNA gene of Bartonella were amplified by polymerase chain reaction (PCR).The PCR products were sequenced and the phylogenetic tree was constructed for homology analysis by biological analysis software.Data on infection rate were analyzed with Chi-square or Fisher exact test to indicate statistical significance.Results showed that 5 917 cages were laid and 381 rodents were captured,density of rodent was 6.44％.The overall Bartonella infection rate in rodents was 12.34 ％,while infection rate in domesticated rodents was 10.61％,with 11.30 ％ in Rattus norvebicus and 10.00％ in R.flavipectus.And the infection rate in wide rodents was 13.86％,with a rate of 22.86％ in Rattus losea and 18.00％ in R.fulvescens,respectively.The infection rate was higher in wild rodents than in domesticated rodents,however,no significant difference was found.The Western Fujian and Northern Fujian region had the higher infection rates of 20.00％ and 25.33％,and no infection was found in Southern Fujian region.The statistical analysis result revealed that a significant difference in infection rate among different region and habitats,but no significant difference in infection rate between male and female rodents,or among different ages.The BLAST results revealed the species to be B.tribocorum,B.elizabethae and B.grahamii.In conclusion,Bartonella infection is found in the rodents in Fujian Province and more attention should be paid on its impact on public health in the province.

BACKGROUND:It is wel-known that vitamin E holds antioxidant capacity, but whether other growth factors have the same effect on endplate chondrocytes has not yet been reported. OBJECTIVE:To observe the effect of different growth factors on the antioxidant ability of endplate chondrocytes in the intervertebral disc. METHODS:Endplate chondrocytes were primary cultured, and then divided into four groups, including blank control, serum deprivation, hydrogen peroxide stimulation and hydrogen peroxide stimulation combined with different growth factors groups. The 4th group was subdivided into insulin-like growth factor-1, basic fibroblast growth factor, transforming growth factorβ, forskolin and vitamin E groups. The expression levels of caspase-3, matrix metal oproteinase 13 and 3, inhibitor of metal oproteinase 1 as wel as thrombin 4 and 5 were detected by real-time PCR. Cel apoptosis was analyzed through apoptosis kit and flow cytometry. Cel synthesis and secretion were detected by western blot assay. The total antioxidant capacity and the hydrogen peroxide content were determined by kit, and then statistical y analyzed. RESULTS AND CONCLUSION:Different growth factors had significant differences in the endplate chondrocyte apoptosis, secretion and antioxidant capacity. To conclude, transforming growth factorβand forskolin do further damage to the cel s stimulated by hydrogen peroxide, while insulin-like growth factor-1 and vitamin E expose protective effect on the injured cel s.
