Objective To investigate the correlation of plasma heme oxygenase-1 (HO-1) level and type 2 diabetes mellitus (T2DM). Methods The outpatient with type 2 diabetes mellitus (T2DM) undergoing oral glucose tolerance test and healthy individuals with physical examination were divided into T2DM group and healthy control group, the differences between the two groups in HO-1 and methane dicarboxylic aldehyde (MDA), mean fluorescence intensity (MFI), homeostasis model assessment of insulin resistance (HOMA-IR) and fasting blood glucose (FBG) were comparatively analysed , and analyzed the correlations between HO-1 and reactive oxygen species (ROS) MFI, MDA, HOMA-IR and FBG. Results The type 2 diabetes group in MDA and MFI, the expression rate of HO-1 were higher than those of control group (P<0.05), correlation analysis of expression of HO-1 was positively correlated with MFI, MDA (r=0.489, 0.763, P<0.05) in the T2DM group, HO-1, HOMA-IR and FBG were significantly higher than the healthy control group, the difference was statistically significant(P<0.05). The expression of HO-1 and HOMA-IR and FPG levels were positively correlated in the T2DM group (r=0.271, 0.426, P <0.05). Conclusion T2DM patients with hyperglycemia and oxidative stress, plasma HO-1 expression is significantly increased, HO-1 is related to oxidative stress, insulin resistance and hyperglycaemia, which has certain value on clinical assessment of T2DM and therapeutic efficacy.

Objective:To investigate the structural alterations of mitochondria and its role in neutrophil death induced by ONO-AE-248.Methods:Human neutrophils were cultured in vitro with ONO-AE-248(5?10-5 mol/L)and medium alone. Transmission electron microscopy(TEM) was used to detect the structural alterations of mitochondria and the level of mitochondria membrane potential by flow cytometry using mitocapture dying.Results:ONO-AE-248 resulted in extremely swollen mitochondria within 6 hours. Meanwhile, a rapid loss of mitochondrial membrane potential of neutrophils occurred, especially in 3 hours and 6 hours. There were obviously differences between spontaneous apoptosis and non-apoptosis programmed cell death induced by ONO-AE-248.Conclusion:The experiment results suggest that changes of mitochondrial structure and function be typically morphological, physiological and biochemical features in this unique form of neutrophil death, and that the mitochondrial pathway might play a more important role in ONO-AE-248-induced death of neutrophils.

Objective:To investigate the roles of apoptosis-associated speck-like protein containing CARD(ASC),one of differentially expressed proteins in neutrophil death induced by ONO-AE-248.Methods:Human neutrophils were cultured in vitro with or without ONO-AE-248(5?10-5 mol/L).The expression of ASC mRNA was detected by RT-PCR.PMN proteins were extracted at 12 h and then separated by 2D electrophoresis.20 differentially expressed proteins were selected and determined by PDQest 2-DE software.Results:ONO-AE-248 decreased the expression of ASC mRNA strikingly in 2 hours;ASC was one of the important differentially expressed proteins between spontaneous apoptosis and non-apoptosis programmed cell death induced by ONO-AE-248 in 12 hour and ASC protein point was weaker in ONO-AE-248 group.Conclusion:ASC might act as double switch that leads to apoptosis of neutrophils in the high expression and removes the forbiddance of pathway of ONO-AE-248 signals in the low expression,resulting in non-apoptosis programmed cell death of neutrophils.

Objective To explore the atypical ultrasonic appearances of breast fibroadenoma and analyze the cause of mis diagnosis.Methods A total of 493 lesions in 485 patients of breast fibroadenoma detected by ultrasound examination andconfirmed by pathology were retrospectively analyzed.Atypical appearances were analyzed and misdiagnosis rate were cal-culated.Statistical methods were taken to compare the misdiagnosis rates in lesions with various atypical appearances andthose with none or single atypical appearance.Misdiagnosis rates in lesions with different sizes and pathological types wereanalyzed statically.Then misdiagnosing causes were analyzed.Results A total of 404 lesions were diagnosed correctly,in-cluding 99 lesions with atypical appearances,and the other 89 lesions were misdiagnosed,which showed atypical appear-ances.The misdiagnosis rate of lesions with ≥2 atypical features was higher than that with none or single atypical feature(x2 =256.40,P＜ 0.05).Large lesions (maximum diameter＞ 3 am) showed higher misdiagnosis rates than small ones(maximum diameter ≤3 cm,x2=6.73,P＜0.05),and complex fibroadenoma lesions also showed higher misdiagnosisrate than simple ones (x2 =188.01,P＜0.05).Conclusion The lesions with various atypical appearances,large size andcomplex fibroadenoma in pathology are easy to be misdiagnosed.

Objective To probe the characteristic ultrasonic appearances of hepatic adenoma.Methods The appearances of color Doppler flow imaging(CDFI)and contrast-enhanced ultrasound(CEUS)in 10 cases of hepatic adenoma were analyzed.Results Rich blood flow signals were found in all the hepatic adenoma lesions on CDFI.Large blood flow signals were detected in the periphery of all tumors.On CEUS,peritumoral feeding vessels displayed in early arterial phase and homogeneous enhancement in arterial phase was observed in all the 4 cases.The tumor capsule was enhanced continuously in all cases.One case with isoechoic enhancement in delayed phase was found the contrast agent wash out in portal phase.The other 3 cases showed the‘fast-in and slow-out'appearance.which was iso-echoic enhancement in portal phase and slightly hyperechoic enhancement in delayed phase.Conclusions The rich blood flow signals,early displaying of peritumoral feeding vessels,homogeneous enhancement in the arterial phase and continuously enhanced tumor capsule on CEUS are the distinctive appearances of hepatic adenoma.

Objective To compare the fatigue characteristics between people with fatigue-predominant sub-health and patients with ulcerative colitis.Methods Fatigue Self-assessment Scale (FSAS) was applied in people with fatigue-predominant sub-health and patients with ulcerative colitis.By using the multivariate statistical analysis,the fatigue characteristics of them were analyzed.Results The fatigue characteristics of two groups of people were different.The scores of physical fatigue,mental fatigue,fatigue consequences,total fatigue,reaction of fatigue after sleep and rest,situation of fatigue in people with fatigue-predominant sub-health were 31.06 ± 17.08,24.63 ± 14.50,24.38±13.39,26.36 ± 11.97,30.63 ± 22.70,42.89 ± 21.47,and in patients with ulcerative colitis were 25.60 ± 22.98,17.80 ± 18.44,20.54 ± 18.53,21.20 ± 17.15,18.18 ± 25.47,41.21 ± 25.70.There were statistical differences on the two groups (P ＜ 0.05 ).There were statistical differences between the percents of four degrees ( unconspicuous,mild,moderate,heavy) of physical fatigue,mental fatigue,fatigue consequences between in people with fatigue-predominant sub-health and in patients with ulcerative colitis (P ＜ 0.05 ).There were statistical differences on the percents of five degrees ( no obvious,slightly,less obvious,obvious,very obvious) of unrelieved fatigue after sleep and rest,situation of fatigue between in people with fatigue-predominant sub-health and in patients with ulcerative colitis (P ＜ 0.05 ).Conclusion The type,severity of fatigue,and characteristics ( such as unrelieved fatigue after sleep and rest,situation of fatigue) are different between people with fatigue-predominant sub-health and patients with ulcerative colitis.

Objective To prepare a sustained-delivery of paclitaxel-loaded thermosensitive hydrogel for the treatment of breast cancer by ultrasound-guided intratumoral injection,and probe the antitumor effect and mechanism of the new method. Methods Paclitaxel-loaded thermosensitive hydrogel was prepared. A total of 40 rats bearing subcutaneous breast tumor were randomized into 4 groups. Each group of rats were administered ultrasound-guided intratumoral injection of different agents as follows: salin, thermosensitive hydrogel, paclitaxel injection and paclitaxel-loaded thermosensitive hydrogel. The tumor nodules were scanned by high frequence ultrasound. The rats were sacrificed on the 14th day,and then the tumors were stripped to calculate the growth inhibitory rate. Histological examinations were undergone and RT-PCR was performed for the detection of bcl-2 and bax expression. Results Greater decrease in average tumor weight was found in paclitaxel-gel group [(16. 04 ± 2. 82)g], compared with that in paclitaxel group [(27.45 ±5.13)g, P ＜0. 05],and tumor growth inhibitory rate in the group was 62.77 %. In this group, blood flow signals reduction was detected on ultrasound and extensive necrosis was found in histological examination. In addition,down-regulation in bcl-2 mRNA expression and up-regulation in bax were found. Conclusions Ultrasound-guided percutaneous intratumoral injection of paclitaxel-loaded thermosensitive hydrogel may provide an effective method for breast tumor ablation therapy. The mechanism may be related to the inhibition of proliferation and induction of apoptosis.

Objective:To summarize our experience in diagnosis and treatment of Budd-Chiari syndrome(BCS) accompanied with hepatic nodules.Methods:The clinical data of 33 patients with BCS accompanied with hepatic nodules who were treated at Henan Provincial People's Hospital from January 2012 to December 2018 were retrospectively analysed. A total of 33 patients were enrolled, including 17 males and 16 females, with an average age of 51 years. Analyze the treatment and prognosis of different types of nodules.Results:Of 33 patients, 27 were diagnosed to have hepatocellular carcinoma and 6 benign proliferative nodules. Treatment of patients with hepatocellular carcinoma included, transcatheter arterial chemoembolization ( n=1) and hepatectomy ( n=26). The survival time of these patients with hepatocellular carcinoma ranged from 10.0 to 78.0 months (mean 37.8 months). For the remaining 6 patients with benign nodules, the nodules were multiple and no malignant changes were observed on follow-up. Conclusion:For patients with BCS associated with benign nodules, no specific treatment was required. Hepatocellular carcinoma assocated with BCS had good prognosis. An aggressive surgical resectional approach is recommended to treat and to relieve the hepatic outflow obstruction.
