Objective Due to the incompleteness and complexity of fault diagnosis for power transformers, a comprehensive rough-fuzzy scheme for solving fault diagnosis problems is presented. Fuzzy set theory is used both for representation of incipient faults' indications and producing a fuzzy granulation of the feature space. Rough set theory is used to obtain dependency rules that model indicative regions in the granulated feature space. The fuzzy membership functions corresponding to the indicative regions, modelled by rules, are stored as cases. Results Diagnostic conclusions are made using a similarity measure based on these membership functions. Each case involves only a reduced number of relevant features making this scheme suitable for fault diagnosis. Conclusion Superiority of this method in terms of classification accuracy and case generation is demonstrated.

Objective To discuss the clinical value of intravascular ultrasound (IVUS) in treatinginternal carotid arteries occlusion.Methods The patient was diagnosed with internal carotid artery occlusionthat was confirmed by CTA.Cerebral perfusion imaging showed that low perfusion area was consistent withischemic symptoms.Guided by IVUS,percutaneous transluminal angioplasty (PTA) was performed.By usingmicro-catheter coaxial technology,the micro guide wire was inserted in the carotid artery until it passedthrough the obstructed segment;After IVUS examination proved that the micro guide wire was in the truelumen of carotid artery,angiography through micro-catheter was carried out to confirm that the distal arterywas unobstructed;after adjusting the device position the embolism protector was placed.The plaque andlumen condition were assessed with IVUS,which was reevaluated after pre-expansion of balloon.After normaldirection blood flow was regained,the plaque stability was assessed with IVUS virtual organization sequence.Simple balloon dilatation therapy was adopted as the fibrous cap of plaque was in stable condition and thelumen stenosis rate was ＜40％.Results After balloon dilatation,the obstructed artery was reopened and theblood flow regained normal direction.IVUS examination showed that during the whole operation process thefibrous cap of plaque at the narrowed segment remained in stable condition,the lumen stenosis rate was ＜40％.Cerebral perfusion imaging revealed that after the treatment the low perfusion state was markedlyimproved.Conclusion IVUS plays an important guiding role in performing PTA for internal carotid arteryocclusion.This technique can increase the success rate of vascular recanalization and reduce the incidence ofcomplications.

Purpose To prepare the sustained-release tablet of tetramethylpyrazine phosphate with hydroxypropylmethylcelluose(HPMC) as matrix material. MethodsThe paddle method and the HPLC method were erspectively used determined the cumulative drug released in vitro and the serum concentration in vivo.ResultsThe cumulative drug released in the first hour was about 20%, while in 12 hours it was above 85%. Drug release behavior can be best described by Higuchi equation, and the release rate decreased as the viscosity and/or the amount of HPMC increased. Compared with the market tablet on the rabbits, the sustained release tablet had the decreased peak concentration (P < 0.05 ); the prolonged peak time and mean residence time (P< 0.05).ConclusionsThe matrix tablet was a good sustained-release dosage form and it had a good in vitro-in vivo correlation.

Objective To investigate the application of the central venous catheter (CVC) specialized for drainage intervention in severe acute pancreatitis (SAP) patients.Methods Sixty-two severe acute pancreatitis patients with seroperitoneum were randomly (random number) assigned into two groups:the drainage group (n =31) and the control group (n =31).All patients were treated with conventional internal medicine therapy.Patients of drainage group were treated with continuous peritoneal drainage by using the central venous catheter.The intra-abdominal pressure (IAP),lactic acid (LAC),and procalcitonin (PCT) were detected before and 12 h,24 h,48 h,72 h,5 days after intraperitoneal drainage.The symptoms of abdomen pain,abdomen distention,resume of bowel movement and the rate of MODS were observed.Results All patients with drainage got catheter successfully inserted.Compared with the control group,the IAP,LAC and PCT decreased significantly in the patients of drainage group.And the duration of abdomen pain,abdomen distention and resume of bowel movement function in the drainage group were shorter and the rate of MODS was lower.Conclusions Application of CVC specialized for intraperitoneal drainage is a safe and effective method for the treatment of pancreatitis with seroperitoneum.It is worthwhile to be widely used in clinic.

Objective To assess the contrast-enhanced ultrasound (CEUS) characteristics of pleomorphic adenoma (PA) and carcinoma ex pleomorphic adenoma (CXPA).Methods A retrospective analyse was made from the contrast-enhanced ultrasonic features of 42 PA and 8 CXPA.The features included tumor size,echotexture,boundary,shape and blood flow richness on conventional US imaging and rise time (RT),time to peak (TP),peak intensity(PI),time from peak to one half(HT),mean transit time (MTT),and area under the curve(AUC) on contrast-enhanced ultrasound.Results All of PA and CXPA were hypoechoic,but there was no difference between them in shape and blood flow richness (P ＞0.05).37.5％ CXPA has hetergeneous echotexture with the presence of anechoic area,but it appeared in only 4.8％ PA(P ＜0.05).The following findings were observed from a perfusion kinetics of CEUS in all of PA and CXPA:slow in,centripetal,heterogeneous enhancement,with no enhancement area.Well-defined margins were presented in 42 PA and in 7 CXPA(P ＜0.05).Their time-intensity curves showed RT,TP,HT and MTT in CXPA group were obviously higher than those in the PA group(P ＜0.05).However there was no statistical difference in PI and AUC between both groups (P ＞ 0.05).Conclusions Conventional US and CEUS perfusion patten provide limited diagnostic information for distinguishing PA from CXPA.CXPA could be diagnosed by ill defined margins,more internal anechoic area and poorly defined margins.But CEUS quantitative analysis can significantly promote the differentiation.

Objective:To compare the similarities and differences of clinical characteristics of human immunodeficiency virus (HIV)-negative and HIV-positive patients with talaromycosis marneffei (TSM).Methods:The clinical data of 175 inpatients diagnosed with TSM in First Affiliated Hospital of Guangxi Medical University from May 2012 to April 2019 were retrospectively analyzed. The patients were divided into HIV-positive group and HIV-negative group according to the results of HIV confirmation test. The clinical manifestations, laboratory examination indicators (white blood cell count, hemoglobin, albumin, CD4 + T lymphocyte count and C-reactive protein (CRP)) between the two groups were compared. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:Among 175 TSM patients, 85 were HIV-positive and 90 were HIV-negative patients. The main clinical manifestations of fever and lymphadenopathy in the HIV-positive group and HIV-negative group were 71 (83.53%) cases and 73 (81.11%) cases, 50 (58.82%) cases and 47 (52.22%) cases, respectively, and there were both no statistical differences ( χ2=0.175 and 0.771, respectively, both P>0.05), while respiratory symptoms, weight loss and subcutaneous masses were 62 (72.94%) cases and 81 (90.00%) cases, 73 (85.88%) cases and 56 (62.22%) cases, one (1.18%) case and 16 (17.78%) cases, respectively, the differences were all statistically significant ( χ2=8.514, 12.630 and 13.737, respectively, all P<0.01). Hemoglobin in HIV-positive group and HIV-negative group were 90.50 (77.00, 113.95) g/L and 88.65 (72.85, 99.93) g/L, respectively. The difference was statistically significant ( Z=2.023, P=0.043). The ratios of albumin<30 g/L, CRP>10 mg/L in the two groups were 69.41%(59/85) and 60.00%(54/90), 94.37%(67/71) and 94.19%(81/86), respectively, and the differences were both not statistically significant ( χ2=1.693 and 0, respectively, both P>0.05). The ratios of cases with white blood cell counts >10×10 9/L and CD4 + T lymphocyte count<50/μL in the positive and negative groups were 3.53%(3/85) and 81.11%(73/90), 80.77%(63/78) and 1.75%(1/57), respectively, the differences were both statistically significant ( χ2=107.095 and 82.467, respectively, both P<0.01). Conclusions:In TSM patients, HIV-negative with subcutaneous masses, and increased white blood cell counts are common. Decreased body weight and CD4 + T lymphocyte count<50/μL in HIV-positive patients are more common than HIV-negative patients.

Objective To investigate the characteristics of coronary vessel re-endothelialization after placement of drug-eluting stents (DES), and to provide clinical evidence for the double anti-platelet treatment. Methods Optical coherence tomography (OCT) was performed in 43 patients in 1 year after DES implantation. Characteristics of re-endothelialization and percentage of neointimal coverage of stent struts were evaluated by OCT. Results The rate of stent struts intimal coverage was 90.70%, and the remain was lack of endothelial coverage; The ratio of neointimal thickness (NIT) between 0-99, 100-199 and above 200 microns was 19.92%, 37.55% and 42.53%, respectively. The rate of neointimal coverage was higher and the degree of neointimal hy-perplasia was more extensive in patients with DM and in patients with ACS than those of patients without DM and of patients with stable angina pectoris. Conclusion One year after stent placement, most of the stent struts were covered with neointima and few struts obtained poor coverage of endothelial. DM and ACS may be impact factors for the progress of re-endothelialization after DES placement.
