Objective To observe the change of 18F-Fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) imaging on lung tumors after treatment of Argon-Helium (Ar-He) cryoablation,and to search the measure for evaluating the short-term curative effect after treatment of Ar-He cryoablation.Methods 19 focuses of 15 patients had completed the treatment of Ar-He cryoablation.All of patients imaged with 18F-FDG PET-CT in six months after Ar-He cryoablation.7 patients of all imaged with 18F-FDG PET-CT pre- and after Ar-He cryoablation.The others only imaged with 18F-FDG PET-CT after cryoablation,but these focuses could compare with tissues near the focus or other tumors in themselves.Results 18F-FDG PET-CT imaging found that there was no accumulation of radionuclide in 13 of 19 focuses after cryoablation and there was no new tumor in follow-up.Two target region of cryoablation,which grew up in mediastinum,were found radiation defect with distinct boundary and expanding outward during 4 months.The other 4 focuses recurred during 6 months in which there was accumulation of radionuclide after cryoablation.There was significant change about SUVmax of focuses after cryoablation by qualitative and quantitative analysis (t =3.784,P ＜0.05).But the changes of SUVmax had no significant difference in different time,between cryoablation and PET-CT imaging (F =0.106,P ＞0.05).Conclusion 18F-FDG PET-CT imaging really reveals the range and effect of Ar-He cryoablation.It is an optimal measure for evaluating the short term curative effect after Ar-He cryoablation.

Objective To study the relationship between the retinal arteriosclerosis prevalence and related factors in in-service teachers from 3 universities. Methods The medical report of in-service teachers from 3 universities from July to October, 2012 were analyzed. Results and Conclusion 2680 cases were included, in which 520 cases (19.4%) were diagnosed as retinal arteriosclerosis. Retinal arteriosclerosis prevalence increased with age and cardiovascular risk factors. In the multi-factor logistic regression analysis, gender, age, hypertension,hyperlipidemia, impaired fasting glucose regulation, diabetes, hyperuricemia are independent risk factors for retinal arteriosclerosis

Objective To explore the expression of Survivin and MHC in non-small cell lung cancer (NSCLC), and their interaction.Methods A total of 40 patients with histologically diagnosed NSCLC were enrolled in this study.Control samples were consisted of normal lung tissues from 15 patients.Expression of Survivin and MHC were detected by flow cytometry in 40 non-small cell lung cancer tissues and 15 normal lung tissues.Results The positive rates of Survivin protein expression in NSCLC tissues classified stages Ⅰ,Ⅱ and Ⅲ were 28.57% ,30.77% and 80.00% respectively.There was a correlation between Survivin protein expres-sion and stages of NSCLC.Survivin protein expression was detected in 19 of 29 patients with lymph node metas-tasis, and 3 of 11 patients with no metastasis.There was a statistically significant difference between the two groups (P<0.030).The loss expression rates of MHC-Ⅰ in NSCLC tissues of low grade,intermediate grade and high grade were 84.62% ,42.10% and 37.50% respectively.There was a correlation in expression be-tween MHC-Ⅰ and tumor grade.The positive rates of MHC-Ⅱ expression in NSCLC tissues was related to pa-thology type (P=0.005).The expression in squamous cancer and non-squamous non-adno cancer was lower than that of adenocarcinoma (P=0.002, P=0.04).There was no obvious correlation between the expression of Survivin and MHC-Ⅰ,MHC-Ⅱ in NSCLC.Conclution The expression of Survivin and MHC could be in-volved in the pathogenesis and development of NSCLC, and the combined detection will predict the prognosis of the patients with NSCLC.

Objective To observe the effects of Hedysari Polysaccharide (HPS) on the expressions of TSP-1 and PDGF-B in the retina of diabetic rats;To discuss the protective effect and possible mechanism on diabetic retinopathy. Methods The diabetic model was established by intraperitoneal injection of streptozotocin. 50 male SPF Wistar rats were randomly divided into 5 groups:model group, calcium dobesilate group, and HPS high-, medium-, and low-dose group, extra 10 rats were set as the normal group, 10 rats in each group. Each administration group was given relevant medicine for gavage, while model group and normal control group were given same amount NS for gavage, once a day for 8 weeks. The mRNA and protein expression of TSP-1 and PDGF-B were detected by qRT-PCR and immunohistochemistry. The retinal structure was observed by HE staining. Results HE staining showed that each layer of the retina of the model group was clear and complete, but the outer nucleus layer became looser, thinner and more disorderly, and the number of ganglion cells decreased slightly; the administration groups were improved markedly compared with the model group. Compared with the normal control group, the mRNA level and protein expression of retina TSP-1 on the model group dramatically dropped (P<0.01), and those of PDGF-B strikingly increased (P<0.01);Compared with the model group, the mRNA level and protein expression of retina TSP-1 on alladministration groups rose (P<0.05, P<0.01), and those of PDGF-B went down (P<0.01); Compared with all other administration groups, there was statistical significance in the mRNA level and protein expression of retina TSP-1 and PDGF-B on HPS high-dose group (P<0.05, P<0.01). Conclusion HPS may prevent the angiogenesis and proliferation in diabetic retinopathy process through adjusting the content of TSP-1 and PDGF-B in retina of diabetic rats so as to protect the retina.

Objective To investigate the clinical features and prognostic factors of nosocomially acquired candidemia.Methods A retrospective analysis was conducted for hospitalized patients with nosocomial candidemia between January 2012 and December 2014 at the First Affiliated Hospital of Anhui Medical University.The univariate and multivariate Logistic regression analyses were used to determine the prognostic factors of candidemia.Results A total of 92 patients were diagnosed with nosocomially acquired candidemia.The most common pathogen was Candida glabrata (C.glabrata,39/92,42.4％),followed by Candida albicans (C.albicans,30/92,32.6％),then Candida krusei (C.krusei,7/92,7.6％),Candida tropicalis (C.tropicalis,5/92,5.4％),Candida parapsilosis (C.parapsilosis,4/92,4.4％) and other Candida spp.(7/92,7.6％).The sensitivity rates of Candida spp.strains against flucytosine,amphotericin B,voriconazole,fluconazole and itraconazol were 100.0％,98.9％,92.4％,82.6％oo and 77.2％,respectively.The 30-day attributable case fatality rate was 13.0％(12/92).Multivariate Logistic regression analyses indicated that presence of central venous catheter (OR=4.833,95％CI:1.010-23.125,P=0.049),invasive mechanical ventilation (OR=6.075,95％CI:1.144-32.257,P=0.034),and receiving hemodialysis (OR =8.367,95 ％ CI:1.390-50.364,P =0.020)were factors independently correlated with increased mortality.Conclusions The pathogens causing nosocomially acquired candidemia are mainly C.glabrata,C.albicans and C.krusei.The drug susceptibility of Candida spp.varies among fluconazole,itraconazol voriconazole.The resistant rates of Candida spp.against voriconazole,fluconazole and itraconazol are different.The presence of central venous catheter,invasive mechanical ventilation and receiving hemodialysis are factors independently correlated with increased mortality.

Objective To observe the effects of hedysari polysaccharide (HPS) on myocardial fibrosis and the expression of MMP-2/TIMP-2 in model mice of diabetic cardiomyopathy; To discuss the mechanism of action of prevention and treatment of myocardial fibrosis in diabetes.Methods Sixty mice were randomly divided into model group, rosiglitazone group and HPS high-, mediume- and low-dose groups. The normal group was 12 non-transgenic male BKS.Cg-Dock7m+/+Leprdb/JNjumice with the same age. Each group was given relevant medicine for gavage, for 8 weeks. Blood glucose of mice before and after medication 2, 4, 6, and 8 weeks was detected. The levels of MMP-2, MMP-2 and MMP-9 in myocardium were measured by Masson staining. The protein expressions of MMP-2 and TIMP-1 in myocardium were detected by Western blot.Results Compared with the model group, the blood glucose of HPS (high- and medium dose) groups and rosiglitazone group decreased significantly. Masson staining showed that the green fibers in the model group significantly increased and rosiglitazone group and HPS high-dose group decreased compared with the model group. Western blot showed that the expressions of MMP-2 in model group and MMP-2/TIMP-2 ratio were declined significantly, while the expression of MMP-2 was increased and TIMP-2 was decreased significantly, and the ratio of MMP-2/TIMP-2 increased in rosiglitazone group and HPS high- and medium-dose group.Conclusion HPS may reduce the degree of myocardial fibrosis in model mice with diabetic cardiomyopathy. The therapeutic effect of HPS may be to relieve myocardial fibrosis in model mice by increasing the ratio of MMP-2/TIMP-2.

Diabetic retinopathy （DR） is one of the most common chronic microvascular complications of diabetes mellitus. It has a high rate of blindness， and the age of onset is gradually getting younger， which seriously affects the physical and mental health and quality of life of patients. The disease is retinal damage induced by diabetes mellitus， which is a kind of fundus disease with the main manifestations of fundus hemorrhage， hard exudation， microhemangioma， cotton-wool spots， neovascularization， etc. In traditional Chinese medicine （TCM）， it is classified into the category of "diabetic cataracts" and other diseases. At present， there is no effective method to prevent the progress of the disease in modern medicine， so it is particularly important to choose a reasonable and effective intervention to prevent and treat DR. Studies have confirmed that TCM has unique advantages in the treatment of DR. It can use its advantages of multiple bioactive components， multiple targets， and multiple pathways to intervene in the development process of DR from various aspects. By searching for the relevant literature on the progress of the intervention of DR with TCM monomers and compounds， this paper mainly reviews the relevant research results of the treatment of DR with multiple signaling pathways such as phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor kappa-B（NF-κB）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor erythroid 2-related factor （Nrf2）/hemeoxygenase-1 （HO-1）， Hippo， advanced glycation end products （AGEs）/receptor for advanced glycation end products （RAGE）， and Akt/glycogen synthase kinase-3β （GSK-3β）， so as to provide more ideas and directions for the clinical prevention and treatment of DR.

OBJECTIVETo compare the differences in the clinical therapeutic effects on juvenile myopia between's stunt needling technique and traditional even needling technique.

METHODSA total of 166 cases of mild juvenile myopia (diopter <-3.00D) were randomized into an observation group ('s stunt needling technique) and a control group (traditional even needling technique), 83 cases in each one (166 affected eyes). Taiyang (EX-HN 5), Fengchi (GB 20), Cuanzhu (BL 2), Hegu (LI 4) and Guangming (GB 37) were used in the two groups. In the observation group, theneedling technique was adopted at Taiyang (EX-HN 5), theneedling technique at Fengchi (GB 20) andneedling technique at Cuanzhu (BL 2). The traditional needling technique was used at Hegu (LI 4) and Guangming (GB 37). In the control group, traditional even needling technique was applied at all the acupoints. The treatment was given once every day, continuously for 6 times as one course. There was 1 day at interval. After treatment for 4 courses, the changes in visual acuity, diopter and axial length were observed before and after treatment. The therapeutic effects were evaluated.

RESULTSAfter treatment, the visual acuity of the naked eyes, and diopter were remarkably improved in the patients of the two groups (all<0.05). The improvements in the observation group were better than those in the control group (both<0.05). The axial length did not change in the two groups (both>0.05). The total effective rate was 78.3% (130/166) in the observation group, which was better than 57.8% (96/166) in the control group (<0.05). .

CONCLUSION 's stunt needling technique effectively improves the vision, rectifies the refractive error and delays the progression of myopia. The therapeutic effects of it are better than traditional even needling technique.
