Objective To quantitatively observe the actual levels of 4977 bp and 3895 bp mitochon-drial DNA (mtDNA) deletion in healthy human skin of different age, and to explore their relationship with intrinsic aging and photoaging. Methods Seventy-one samples of skin tissue were obtained from healthy volunteers, including 40 samples from UV-protected areas (buttock, thigh, waist or abdomen) and 31 from UV-exposed areas (neck, back of hands, forehead or face). Nuclear and mitochundrial DNA was extracted from these samples. Conventional PCR was performed to detect the incidence of 4977 bp and 3895 bp mtDNA deletion. Then, SYBR Green real-time PCR was applied to quantitatively analyze the target mutations in posi-tive samples. Results Conventional PCR showed that the incidence of both 4977 bp deletion and 3895 bp deletion increased with age. For example, the incidence of 4977 bp deletion and 3895 bp deletion accounted for 47.5% (19/40) and 30% (12/40), respectively in samples from volunteers older than 40 years, signifi-cantly higher than that in those from volunteers younger than 40 years (X2 = 4.673, 6.118, respectively, both P < 0.05). The total incidence of 4977 bp deletion and 3895 bp deletion in UV-exposed areas was 48.4% (15/31) and 32.3% (9/31), respectively, which did not differ from those in UV-protected areas. The results from real-time PCR revealed a positive correlation of the copy number of 4977 10p deletion and 3895 bp deletion with age (rg = 0.907, 0.845, respectively, both P < 0.05). When the UV-exposed area was compared with the UV-protected area, no significant difference was found in the copy number of 4977 bp deletion ( P = 0.264), whereas a higher level of 3895 bp deletion was noticed in UV-exposed area (P = 0.014). Conclu-sions The 4977 bp mtDNA deletion is primarily associated with chronological aging, and might serve as a biomarker for the process of chronological aging of skin. Deletion of 3895 bp mtDNA seems to be more sus-ceptible to ultraviolet radiation.

Objective To investigate the effects of edaravone on myocardial fibrosis induced by isoproterenol (ISO) in rats, and to discuss the correlation between the level of transforming growth factor-β1 (TGF-β1) and the myocardial fibrosis. Methods Forty male SD rats were randomly divided into five groups, namely control group, model group and edaravone groups (low, medium and high doses). Isoproterenol was used to establish the rat model of myocardial fibrosis. Edaravone groups were given edaravone [3, 5 and 10 mg/(kg · d)] to intervene for 14 days. The activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) were examined after 15-d treatment. The left ventricular mass index (LVMI) and collagen volume fraction (CVF) were examined. The expression of TGF-β1 was detected by Western blot assay and immuno-fluorescence method. Results The content of MDA and LVMI were significantly higher in model group than those of the control group (P<0.01),whereas the content of SOD was significantly lower in model group than that of the control group (P<0.01). Compared with model group, the expression level of MDA decreased with the increased intervention dose of edara-vone (P<0.05), while SOD expression level increased (P<0.05). There was no significant difference in the level of SOD be-tween middle dose edaravone group and the control group. LVMI was decreased with the increased doses of edaravone ( P<0.01). There was no significant difference in LVMI between the high dose of edaravone group and the control group. Com-pared with the control group, the expression level of TGF-β1 was significantly increased in model group (P<0.01). The ex-pression level of TGF-β1 was reduced with the increased doses of edaravone. CVF was significantly increased in model group compared with that of control group (P<0.001). CVF decreased with the increased doses of edaravone in medium and high doses of edaravone groups, but they were higher than that of control group (P<0.01). TGF-β1 was positively correlated with MDA, LVMI and CVF (r=0.931, 0.879 and 0.930, P<0.001). SOD was negatively correlated with TGF-β1 (r=-0.892, P<0.001). Conclusion Edaravone can relieve myocardial fibrosis by inhibiting oxidative stress and TGF-β1 in rats.

Interleukin-22 (IL-22) is a member of the IL-10 family, which exhibits a similar structure and immune function with IL-10. IL-22 is mainly secreted by Th22, Th1, and Th17 cells, innate lymphoid cells (ILCs), and γδT and NKT cells. IL-22 is mainly in-volved in autoimmune diseases, malignant tumors, and infective diseases. As such, studies have focused on the function of IL-22 cyto-kine in the pathogenesis of various malignant tumors. Studies revealing the expression and pathogenesis of IL-22 in malignant tumors possibly provide a new method to treat and prevent malignant tumors. In our study, the discovery, structural characteristics, and func-tions of IL-22 in malignant tumors are reviewed.

Objective To explore the relationship between the MRI enhancement ratios of liver parenchyma in hepatobiliary phase with gadobenate dimeglumine (Gd-BOPTA)and liver function.Methods Fifty-nine patients who underwent Gd-BOPTA-enhanced MRI were retrospectively enrolled in the study.The enhancement ratio of signal to noise ratio and enhancement ratio of the contrast ratio were calculated.The relationships between the enhancement ratio and CTP grading and MELD score were analyzed.Results The signal enhancement ratios in hepatobiliary phase in patients with CTP A classification were higher than those with CTP B classi-fication (P <0.01).Meanwhile,the ratios in patients with MELD scores less than 10 points were higher than those with MELD scores more than 10 points (P <0.01).Conclusion The MR enhancement degree of liver parenchyma in the hepatobiliary phase with Gd-BOPTA may reflect the liver function.

Objective To investigate the application effect of anterior clinoid process drilled off via epidural approach in posterior communicating artery aneurysm ( PCoAA) clipping. Methods The clinical data of 42 patients with PCoAA who underwent craniotomy from January 2012 to January 2014 were analyzed retrospectively,including 22 patients performed anterior clinoid process drilled off and 20 did not. The difficult or easy degree of intraoperative aneurysm clipping and postoperative efficacy were analyzed. Results The aneurysms in 22 patients underwent anterior clinoid process were clipped satisfactorily. The brain retractor was not used during the procedure. Only one patient had cerebral infarction after procedure. No patients had oculomotor nerve paralysis and incomplete clipping of aneurysms. Of the 20 patients without the anterior clinoid process drilled off,3 aneurysms were clipped incompletely because it was difficult to implant aneurysm clips, 2 had cerebral infarction, and 1 had oculomotor nerve paralysis. Conclusion Removing the anterior clinoid process drilled off via extradural approach may bring convenience for PCoAA clipping. It can effectively avoid the difficulty of implanting aneurysm clips during the procedure. Its application is safe and can reduce postoperative complications.

Objective: To investigate the correlation of thrombospondin-1(TSP-1) expression and angiogenesis and clinical pathologic factors in breast cancer. Methods:Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of TSP-1 mRNA in the primary breast cancer tissues and the tissues set apart 5 cm from the tumor. Im-munohistochemistry was used to detect the expressions of vascular endothelial growth factor (VEGF), c-erbB2, estrogen receptor (ER), progesterone receptor (PR) and microvessel density (MVD). All data were statistically analyzed. Results: The positive rate of TSP-1 was significantly higher in breast cancer than that in tissues set apart 5 cm from tumor (P < 0.05). The expression of TSP-1 was positively correlated with tumor size only (P < 0.05). MVD was lower in TSP-1 positive group than that of negative group (P< 0.05). Conclusion: The MVD was decreased with up-regulation of TSP-1 expression. Thrombospondin-1 may repress the angiogenesis in breast cancer.

OBJECTIVE To investigate the transmission of microorganisms by humidifier during oxygen humidification and search an ideal way to prevent it.METHODS Two kinds of humidifier,the unique bionic humidifier and the bubble humidifier,were involved.The humidification material inside the humidifiers were all contaminated with Staphylococcus aureaus,Escherichia coli and Candida albican at 5?105/ml and 2.5?106/ml.Oxygen passed through every contaminated humidifier to the end of oxygen tube which was put in the bottle with 100ml normal saline,lasting 20 minutes,on the 1st,the 2nd,and the 3rd day after the humidifiers being contaminated.The fluid in the bottles,1ml each,were cultured respectively.RESULTS The S.aureaus count of 39.5,52.4,117.3 CFU/ml in 5?105/ml group,83.1,125.2,263.2 CFU/ml in 2.5?106/ml group and E.coli count of 12.9,29.4,37.3 CFU/ml in 5?105/ml group,26.5,55.2,65.2 CFU/ml in 2.5?106/ml group were detected at the end of bubble humidifier on three consecutive day respectively.There were no positive culture of bacteria at the end of bionic humidifier on three consecutive day respectively.The difference of S.aureaus and E.coli count between bubble and bionic humidifier on three consecutive day was significant(P

Objective:To investigate the relationship between human papilloma virus (HPV)16 E6/7-specific T cell immune response in the periphral blood and clinical features and prognosis of patients with cervical squamous cell carcinoma (CSCC).Methods:Seventy-two patients pathologically diagnosed with CSCC admitted to Affiliated Tumor Hospital of Xinjiang Medical University from June 2013 to October 2015, and 75 healthy controls were enrolled in this study. The special responses of peripheral blood T cells to E6 and E7 overlapping peptides before treatment were detected by enzyme-linked immunosorbent assay (ELISA). The differences of frequency and intensity expression of specific immune responses between two groups were analyzed by chi-square χ2 test and nonparametric test. The correlation between antigen-specific immune response and T cell subsets was analyzed by Spearman test. Log-rank test and Cox’s regression model were employed for univariate and multivariate prognostic analyses. Results:The frequencies of HPV16 E6-ad E7-specific T cell responses in CSCC patients were significantly higher than those in healthy controls (51.39% vs. 29.33%, P=0.006 and 45.83% vs.25.33%, P=0.009), and the mean intensities were also considerably higher than those in healthy controls (20.00 SFC/10 6vs.10.76 SFC/10 6, P<0.001 and 16.17 SFC/10 6vs.10.72 SFC/10 6, P=0.017). The intensity of HPV16 E6-specific T cell immune response was positively correlated with the CD 4+/CD 8+ ratio in the peripheral blood of CSCC patients ( r=0.279, P=0.018). And a strong correlation was noted between E7-specific T cell immune response intensity and increasing proportion of NK+ cells ( r=0.274, P=0.020). Univariate and multivariate analyses showed that therapeutic mode (radiotherapy vs. concurrent chemoradiotherapy, HR=2.918, 95% CI 1.454-5.854, P=0.003) and E6-specific T cell response (response group vs. no response group, HR=0.491, 95% CI 0.243-0.99, P=0.047) were the independent prognostic factors influencing the clinical prognosis. The 5-year overall survival in patients with HPV16 E6-specific T cell responses was significantly higher than that in the no response group (64% vs.41%, P=0.041). Conclusions:The intensity of HPV16 E6-specific T cell immune response is positively correlated with the CD 4+/CD 8+ ratio. No HPV16 E6-specific T cell response and radiotherapy alone are more likely to cause poor prognosis of CSCC patients.

Objective To study the prognostic factors of survival in patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib.Methods From May 2008 to Dec 2012,the clinical data of 82 cases with mRCC adminstered by sunitinib were reviewed retrospectively.The study included 60 male patients and 22 female patients,whose age ranged from 29 to 82 years [mean (56.1±11.3) years].Among them,52 cases presented hematuria,flank pain and palpable mass.The size of renal tumor ranged from 2.0 to 18.0 cm [mean (8.0±3.0) cm].The location of tumor included 41 in left kidney,37 in right kidney and 4 in bilateral kidney.The pathological tissue obtained from the operation in 69 cases and from biopsy in 13 cases.The pathological results demonstrated renal cell carcinoma in 75 cases,papillary cell carcinoma in 2 cases,chromophobe cell carcinoma in 2 cases,sarcomatoid carcinoma in 2 cases,collecting duct carcinoma in one case.The site of metastasis included lung in 50 cases,liver in 11 cases,bone in 14 cases,pancrease in 3 cases,retroperitoneal lymph node in 31 cases.In 52 cases,the ECOG scores ranged from 1 to 2.The others scores were more than 3.The average level of hemoglobin,AKP,LDH and leukocyte were (132±24)g/L,(90±65) U/L,(168±114) U/L and (6.4±2.0)×109/L,respectively.Before treatment,the abnormal cases in those parameters were 59,9,6 and 2,respectively.According to the MSKCC risk model,14 cases were classified into the high risk group and 68 cases into medium risk group.74 cases were accepted the sunitinb therapy within one year after diagnosis and 8 cases were accepted same therapy until one year after diagnosis.The overall survival (OS) rates were calculated by Kaplan-Meier method and Cox regression model was used to analyze the relationship between the influencing factors and the prognosis.Results The average OS was (21.6± 14.1) months (ranged 2.8 to 64.1 months).The survival rate at 1 st,2nd and 3rd year were 71％,64％ and 58％,respectively.Single factor analysis showed that significant prognostic factors were as follows:ECOG performance status ≥ 2 (P =0.005),clinical symptom during first clinic visiting (P =0.031),without nephrectomy (P =0.012),the number of metastatic sites ≥ 2 (P =0.015),hemoglobin before treatment (P=0.005),serum AKP level before treatment (＞126 U/L) (P=0.007),MSKCC score≥ 3 (P =0.000),the presence of liver metastases (P =0.000) and bone metastases (P =0.000) and relative dose intensity in the first month (1M-RDI) of sunitinib ≥ 50％ (P=0.000).Cox regression model showed that the beneficial predictive factors were ECOG performance status＜2 (P=0.136),no symptom during the first clinic visiting (P=0.801),serum AKP ＜126 U/L (P=0.618) before treatment,the absence of bone (P =0.068) and pancreas metastases (P =0.265).Sunitinib 1M-RDI ≥ 50％ was the independent predictive factor (P=0.000).Conclusions In targeted therapy era,there is some change in the prognostic factors for mRCC and target drug play an important role in the prognosis of mRCC.Sunitinib 1M-RDI ≥50％ is the independent predictive factor for the prognosis of renal carcinoma.
