Aim To study the effect of adiponectin ( APN) on myocardial ischemia reperfusion( IR) injury in diabetic rats and to explore the role of oxidation-an-tioxidation system. Methods Male Sprague Dawley rats were randomly divided into control group( NS) , IR group ( NIR ) , diabetes group ( DS ) , DS + IR group (DIR), DS +APN +IR group(APN). Experimental diabetes was induced in the animals by a single intrap-eritoneal injection of streptozotocin at a dose of 55 mg ·kg-1 . The IR and NIR group were subjected to myo-cardial I/R injury. APN group was administered APN through intravenous injection 10 min before the reper-fusion, the others were administered normal saline. The rats were considered diabetic and used for the study only if their glucose levels were higher than 15 mmol·L-1. Results All the diabetic rats exhibited increased levels of blood glucose and reduction of body weight ( P <0. 05 ) . Compared with those of NS and DS groups, the myocardial infarct size, cardiomyocyte apoptosis, MDA concentration and ROS in NIR and DIR groups were remarkably increased, activities of SOD and NO were decreased(P<0. 05 or P<0. 01). APN decreased oxidative stress product generation and myocardial apoptosis induced by diabetic myocardial I/R injury ( P <0. 05 ) . Conclusion APN exerts pro-tective effect on myocardial I/R injury in diabetic rats through anti-oxidative mechanism.

Securin is a multifunctional protein which is encoded by PTTG gene.In the metaphase to anaphase transition during mitosis,Securin is involved in sister chromatid separation.The aberrant expression of Securin is found in many endocrine and related cancers,such as pituitary tomour,thyroid cancer,ovarian cancer,colon cancer et al.The function of Securin in cancer is related to its gene transactivation and association with other poteins like p21,p53.

BACKGROUND:With the deepen understanding on the biological function of Rho/ROCK pathway, new ROCK inhibitors continue to be discovered, and ROCK inhibitors show good promoting effects on the survival, proliferation and migration of keratocytes. Research on ROCK inhibitors wil provide more donor materials or seed cels for regenerative medicine and clinical cel transplantation. OBJECTIVE:To summarize and explore the progress in the treatment and application of corneal disease using the ROCK inhibitors Y-27632 and Y-39983. METHODS:The PubMed database and CNKI database were retrieved by computer to search the relevant literature published between 2008 to 2015 using the key words of “corneal endothelial cel, corneal epithelial cel, ROCK inhibitor, Y-39983, Y-27632” in English and Chinese, respectively. Relevant articles in line with the theme were screened and analyzed. RESULTS AND CONCLUSION:Totaly 264 papers were initialy searched. At last, 45 papers were selected. Currently there are two main ROCK inhibitors: Y-27632 and Y-39983, but both of which are stil in basic research stage and clinical testing stage. Y-27632 promotes the proliferation and activity of corneal epithelial stem cel after resuscitation; Y-39983 as a novel ROCK inhibitor can be better to inhibit Rho kinases activity than Y-27632, thereby more effectively promoting the healing of the corneal endothelium. There are many studies on the application of ROCK inhibitors in corneal treatment, but not a stable method established to obtain seed cels. Each method has its own advantages and disadvantages, and how to overcome these disadvantages and to find fast and stable access to seed cels is the future direction of development.

Objective To analyze the treatment effect and factors affecting the prognosis in young people of papillary thyroid carcinoma (PTC).Methods A total of 69 PTC patients were reviewed retrospectively in Sun Yatsen University Cancer Center from Dec 1996 to Oct 2005.The prognostic status were compared using the Kaplan-Meier methods,the factors were analyzed by Log-rank test and the multiple factors were estimated by the Cox regression models.Results There were 26 males and 43 females.The median age was 24 years (mean:23.1 years).The average follow-up time was 113 months ranging from 73 to 174 months.20.3％ patients (14/69) experienced recurrence during follow-up time and 1.4％ patient (1/69) died.All the patients received levothyroxine after operation.The 10 year disease-free survival (DFS) rate of patients with or without extra thyroidal extension (ETE) of PTC was 29.6％ and 80.1％,respectively (P ＜ 0.01).Multivariate analysis showed that young PTC people with ETE had a worse prognosis (P =0.004).Conclusions Young papillary thyroid carcinoma patients had a favorable outcome.Surgical procedure was the first choice for this kind of patients.ETE was an independent factor for the recurrence of young PTC patients.

Objective This aim of this study was to understand the distribution of pretreatment serum LDH in NPC of each radiotherapy-related typing,and its relationship with prognosis.Methods We collected the pretreatment data of LDH in 2 665 newly diagnosed NPC who underwent radical radiotherapy between January 1,2000 and December 31,2005 at Sun Yat-sen University Cancer Center.Pretreatment serum LDH levels and survival analysis were analyzed in four kinds of radiotherapy-related typing of NPC.Results Distribution of radiotherapy-related types of 2 665 NPC were 74.6％ (1 987 cases),15.1％ (404 cases),8.6％ (229 cases),1.7％ (45 cases) for Types Ⅰ (no primary and regional recurrence and no distant metastasis),Ⅱ (primary or regional and no distant metastasis),ⅢⅡ (no primary and regional recurrence,and distant metastasis),Ⅳ (primary or regional recurrence,and distant metastasis),respectively.Increased LDH patients Ⅰ,Ⅱ,Ⅲ,Ⅳ-type proportion were:9.6％ (191/1 987),15.8％ (64/404),18.8％ (43/229),35.6％ (16/45).274 cases of type Ⅲ and Ⅳ,there were 81 cases of liver metastasis,which increased LDH levels in 34 cases,accounted for 42％.Total follow-up rate was 95.2％.The OS,LRFS,and DMFS curves for the increased LDH level group and the normal LDH level group was significant (P =0.000,0.000,0.000).Further analysis showed that the above main difference caused by the type Ⅱ (P =0.000).Conclusions Pretreatment levels of serum LDH are associated with radiotherapyrelated typing of NPC,particularly associated with type Ⅲ and type Ⅳ liver metastasis.And mainly type Ⅱ has poor prognosis.

Objective To establish a real-time quantitative polymerase chain reaction (RQ-PCR) assay for fast detection of Aspergillus fumigatus genome in human whole blood samples and explore its clinical application.Methods The primers and the TaqMan-probe were designed on the basis of the multi-copy ITS1-5. 8S region of the rDNA of Aspergillus fumigatus. The Aspergillus fumigatus genomic DNA were extracted with QIAamp(R) DNA Blood Mini Kit.A 20 μl RQ-PCR amplification system was established, and the simulated blood samples containing various given load of Aspergillus fumigatus genome and the 66 whole blood samples of the surgical febrile patients were examined. Results The detection limit of the RQ-PCR instrument is 10-1 genomes/μl DNA sample,namely 78 CFU/ml whole blood. The specificity and the sensitivity were 94. 25% and 99. 04% respectively; and the positive predictive value and negative predictive value were 97. 63% and 97. 62% respectively. The average relative error of the quantitative results was (3. 67 ±13. 19)%, and the intra- and the inter-assay average coefficients of variation were (12.38 ± 1. 53)% and (16. 27 ±2. 72)% , respectively. The average recovery rate of Aspergillus fumigatus genomic DNA in human whole blood samples was (107. 81 ±25. 92)% , and the average coefficient of variation of the average recovery rate was (26. 24 ± 5.62) % . No Aspergillus fumigatus genomic DNA was detected among the 66 blood samples of the surgical febrile patients. Conclusions The RQ-PCR assay for fast quantitative detection of Aspergillus fumigatus genome in human whole blood samples is of high sensitivity, specificity,accuracy and precision. The Aspergillus fumigatus genome was not detected in this group of surgical febrile patients.

Objective:To investigate the feasibility and safety of endovascular repair for traumatic thoracic aortic pseudoaneurysm.Methods:From Oct 2015 to Oct 2018, the clinical and followup data of 7 patients diagnosed as traumatic thoracic aortic pseudoaneurysm in Fuwai Hospital of Chinese Academy of Medical Sciences were analyzed retrospectively.Results:The patients average age was (51.2±11.0) years old. All patients underwent surgery in the hybrid operating room under general anesthesia. Two did thoracic endovascular aortic repair (TEVAR), three did TEVAR combined with chimney technique to reconstruct the left subclavian artery, and 1 had TEVAR combined with fenestration to reconstruct the left subclavian artery. One did TEVAR with left common carotid artery and left subclavian artery bypass. The mean operative time was (90.1±27.4) min, the mean postoperative hospital stay was (8.9±3.7) d, and the mean postoperative follow-up time was 42.4 months. All the patients received CTA reexamination of the aorta after 1, 6, 12 months and yearly thereafter. TypeⅠendoleak was found in one patient with chimney technique to reconstruct of left subclavian artery after operation. CT showed that the type Ⅰ endoleak disappeared 6 months after operation. There was no death, paraplegia or stroke during the perioperative period and follow-up period, and there was no aortic related reintervention.Conclusion:TEVAR is a safe and effective method for the treatment of traumatic pseudoaneurysm of thoracic aorta, and the early and mid-term results were satisfactory.

The protein product of metastasis-associated in colon cancer 1 (MACC1) gene induces the activation of hepatocyte growth factor/mesenchymal-epithelial transition factor (HGF/c-Met) signaling pathway through transcriptionally activating c-Met gene and upregulating its expression to further promote tumor invasion and metastasis.High level expression of MACC1 is associated with the occurrence and metastasis of a wide variety of human tumors, such as colon cancer, gastric cancer, liver cancer, lung cancer, ovarian cancer etc.In addition, the overexpression of MACC1 is also closely associated with clinical TNM stages and distant metastasis.Thus, MACC1 can serve as an independent indicator of tumor metastasis and prognosis, and become a new target for gene therapy.
