These anatomical and functional changes predispose to complications like peritonitis,encapsulating peritoneal sclerosis and ultrafiltration failure. In recent years, "biocompatible" and glucosesparing PD regimens have been developed to minimize damage to the peritoneal membrane. Can the use of these more expensive solutions be justified on current evidence? In this review of the literature, we explore how we may individualize the prescription of biocompatible PD fluid.展开更多

Methods: TGF-β1, ADAM12 and HB-EGF were detected by RT-PCR and immunohistochemistry in 30 cases of hepatic carcinoma tissues, 30 cases of adjacent carci- noma tissues and 5 cases of normal hepatic tissues. Results: RT-PCR analyses showed that the mRNA expression of TGF-β1, ADAM12 and HB-EGF were markedly increased in each hepatic carcinoma tissue compared with its adjacent tissue (P < 0.01), but no signal was detected in normal hepatic tissue. Immunohistochemistry showed the same outcome on the expression of above three factors in hepatic tissues as RT-PCR. Proteins location analyses showed the proteins of TGF-β1, ADAM12 and HB-EGF all distributed in the stroma of hepatic carcinoma tissues. The positive correlation was found between TGF-β1 and ADAM12 (r = 0.6137, P < 0.05), as well as ADAM12 and HB-EGF (r = 0.5763, P < 0.05). The protein expression of TGF-β1, ADAM12 and HB-EGF were correlated with the size of tumors, degree of differentiation of hepatoma carcinoma cells, portal vein thrombus and the metastasis of absorbent glands, especially with hepatic cirrhosis caused by hepatitis B virus. Conclu- sion: TGF-β1, ADAM12 and HB-EGF possibly play an important role in the process of growth, invasion and metastasis of hepatoma carcinoma cell, meanwhile, the above three factors may collectively participate in the transition from hepatic cirrhosis caused by hepatitis B virus to hepatocellular carcinoma.展开更多

At the same time, the world is increasingly concerned about TCM, and many studies have been conducted to investigate different aspects of TCM. Among these studies, metabolomic approach has been implemented to facilitate TCM development. The current methods for TCM research are diverse, including nuclear magnetic resonance, gas chromatography-mass spectrometry, and liquid chromatographymass spectrometry. Using these techniques, some advantageous results have been obtained in the studies of TCM, such as diagnosis and treatment, quality control, and mechanisms of action. It is believed that the further development of metabo-lomic analytical techniques is benefcial to the modernization of TCM. This review summarizes potential applications of metabolomics in the area of TCM. Guidelines for good practice for the application of metabolomics in TCM research are also proposed, and the special role of metabolomics in TCM is highlighted.展开更多

Most of researches on Wuxing theory are based on the paradigm of TCM or Traditional Chinese Culture. It is an evitable challenge to interpret Wuxing theory in the term of biomolecular, biochemistry, stem cell and so on. The oxidation of glucose is the important pathway in cell and there are five basic factors which will be responsible for the undergoing of this reaction. The relationships among these factors are similar to Wuxing theory just like inter-promotion and inter-restraint. So, this understanding on Wuxing theory maybe take some advancement for the modernization of TCM.展开更多

CardioGRAF is a novel programmer based on the ECG gated single photon emission computed tomography (G-SPECT) imaging to detect LV systolic and diastolic dyssynchrony simultaneously. This study was to investigate the prevalence of systolic and diastolic left ventricular (LV) dyssynchrony in patients with heart failure. Methods We retrospectively studied 69 patients with heart disease, including 31 patients who had symptoms of heart failure (NYHA class Ⅱ-Ⅲ), and 38 patients who had no symptoms of heart failure. (NYHA class Ⅰ). G- SPECT data were analyzed by cardiaGRAF, and measurements included the time to end systole (TES), the time to peak ejection (TPE), the time to peak filling (TPF), TES+TPF and maximal difference (MD) of each parameters were obtained, using the 95th percentile of the control group as a cutoffof 150 ms for MD-TES, 139 ms for MD-TPE, 345 ms for MD-TPF and 315 ms for MD-TES+TPF. Results The prevalence of LV systolic dyssynchrony was significantly higher in heart failure patients with reduced LV ejection fraction (LVEF)〈45% (72% for MD-TES; 64% for MD-TPE) compared with heart failure patients with preserved LVEF=45% (14% for both MD-TES and MD-TPE; P=0.002, P=0.005, respectively); The prevalence of MD-TES〈150 ms was higher in NYHA class Ⅲ patients (64%) compared with NYHA class Ilpatients (27%, P=0.049). However, the prevalence of the LV diastolic dyssynchrony were high but not difference between NYHA class III(47% for both MD-TPF and MD-TES+TPF) and class Ⅲ(63% for MD-TPF; 69% for MD-TES+TPF; P=NS) patients as well as between patients with preserved LVEF (43% for both MD-TPF and MD-TES+TPF) and patients with reduced LVEF(64% for MD-TPF; 72% for MD-TES+TPF; P=NS). Conclusions The prevalence of LV systolic dyssynchrony was high in heart failure patients with reduced LVEF. Diastolic dyssynchrony was common in patients with heart failure. CardioGRAF maybe a useful method to detect LV dyssynchrony (J Gerlatr Cardio12009; 6:151-156).展开更多

Methods: Twenty Wistar rats were allocated to two groups. One was moxibustion-group (10 rats), and the other was non-moxibustion-group (10 rats). Four ignited moxa-cones were applied to bilateral “Shenshu” (肾俞 BL 23). When a moxa-cone burned out, another one was replaced. At the end of each experiment, blood sample (2 mL/rat) was collected from the heart for assaying plasma adrenalin, noradrenaline and dopamine contents with high pressure liquid chromatography. Results: The presented results showed that plasma adrenalin and noradrenaline contents of moxibustion-group are significantly higher than those of non-moxibustion-group (P 〈 0.01). However, there is no significant difference of dopamine between moxibustion-and non-moxibustion-groups (P 〉 0.05). Conclusion: These results demonstrated that moxibustion stimulates the secretion of adrenaline and noradrenaline in normal rats.展开更多

Methods: According to medical records of inpatients, demographicinformation, etiology, clinical features and treatment information were collected. Results: A total of 610 cases withheart failure from our hospital between July 2010 and June 2016 were analyzed. The average age of all the patientswas 63. Males accounted for 50.49%. There were 82.7% patients with NYHA functional classification at III-IV.31.3% patients with coronary artery disease, 28.4% with rheumatic heart diseases and 21.8% with expansion ofheart disease. 27.4 percent of the patients with the left ventricular ejection fraction lower than 40%. There were78.9% patients received aldosterone antagonist treatment, 63.4% received ACEI/ARB, 62.1% received digoxin,59.8% received beta blockers, and 75.4% patients received decoction, and 80.8% received Chinese patent medicine.Conclusion: The study has shown that high utilization of traditional Chinese medicine is to highlight theadvantages of the combination of traditional Chinese and western medicine in the treatment of heart failure. Theusage of spironolactone, ACEI/ARB, beta blockers in our hospital was lower than the ratio reported, higher thanthat of the national average. However, the use of diureticis is lower than that of national average, which may relateto the use of damp-clearing herbs. Clinicians should pay attention to the high utilization rate of digoxin. Patientswith the left ventricular ejection fraction 〉 50% accounted for 61.1%, which required more attention should be paidto the diagnosis and treatment of patients with heart failure of the ejection fraction remains.展开更多

The study of negative pressure aspi- rator is an important goal pursued in emergency treatment, became it can boost aid success. Given this need, this device based on MXT8051 single-chip is developed. The device can use Pulse Width Modulation (PWM) signal to drive the motor of negative pressure pump and it can adjust the motor's speed through the Proportional In- tegral Derivative (PID) algorithm to realize the setting negative pressure rapidly, aoctarately and stably. The control requiroemnt is accomplishedthrough the nmn-machine interface. This device has the advantage of simple operation, low cost and good practicability.展开更多
文摘A major concern inhibiting some clinicians from embracing peritoneal dialysis(PD) as the preferred first modality of dialysis is the effects of PD solutions on the peritoneal membrane. These anatomical and functional changes predispose to complications like peritonitis,encapsulating peritoneal sclerosis and ultrafiltration failure.

文摘Despite the growing use of medical salvage therapy,colectomy has remained a cornerstone in managing acute severe ulcerative colitis(ASC) both in children and in adults.Colectomy should be regarded as a life saving procedure in ASC,and must be seriously considered in any steroid-refractory patient.However,colectomy is not a cure for the disease but rather the substitution of a large problem with smaller problems,including fecal incontinence,pouchitis,irritable pouch syndrome,cuffitis,anastomotic ulcer and stenosis,missed or de-novo Crohn's disease and,in young females,reduced fecundity.This notion has led to the widespread practice of offering medical salvage therapy before colectomy in most patients without surgical abdomen or toxic megacolon.Medical salvage therapies which have proved effective in the clinical trial setting include cyclosporine,tacrolimus and infliximab,which seem equally effective in the short term.Validated predictive rules can identify a subset of patients who will eventually fail corticosteroid therapy after only 3-5 d of steroid therapy with an accuracy of 85%-95%.This accuracy is sufficiently high for initiat-ing medical therapy,but usually not colectomy,early in the admission without delaying colectomy if required.This approach has reduced the colectomy rate in ASC from 30%-70% in the past to 10%-20% nowadays,and the mortality rate from over 70% in the 1930s to about 1%.In general,restorative proctocolectomy(ileoanal pouch or ileal pouch-anal anastomosis),especially the J-pouch,is preferred over straight pullthrough(ileo-anal) or ileo-rectal anastomosis,which may still be considered in young females concerned about infertility.Colectomy in the acute severe colitis setting,is usually performed in three steps due to the severity of the inflammation,concurrent steroid treatment and the generally reduced clinical condition.The first surgical step involves colectomy and constructing an ileal stoma,the second-constructing the pouch and the third-closing the stoma.This review focuses on the role of surgical treatment in ulcerative colitis in the era of medical rescue therapy.

At the end of each experiment, blood sample (2 mL/rat) was collected from the heart for assaying plasma adrenalin, noradrenaline and dopamine contents with high pressure liquid chromatography. Results: The presented results showed that plasma adrenalin and noradrenaline contents of moxibustion-group are significantly higher than those of non-moxibustion-group (P 〈 0.01). However, there is no significant difference of dopamine between moxibustion-and non-moxibustion-groups (P 〉 0.05). Conclusion: These results demonstrated that moxibustion stimulates the secretion of adrenaline and noradrenaline in normal rats.
文摘Objective: To analyze the clinical characteristics and medical treatment of hospitalized patients with chronic heartfailure, and provide medication for the patients. Methods: According to medical records of inpatients, demographicinformation, etiology, clinical features and treatment information were collected. Results: A total of 610 cases withheart failure from our hospital between July 2010 and June 2016 were analyzed. The average age of all the patientswas 63. Males accounted for 50.49%. There were 82.7% patients with NYHA functional classification at III-IV.31.3% patients with coronary artery disease, 28.4% with rheumatic heart diseases and 21.8% with expansion ofheart disease. 27.4 percent of the patients with the left ventricular ejection fraction lower than 40%. There were78.9% patients received aldosterone antagonist treatment, 63.4% received ACEI/ARB, 62.1% received digoxin,59.8% received beta blockers, and 75.4% patients received decoction, and 80.8% received Chinese patent medicine.Conclusion: The study has shown that high utilization of traditional Chinese medicine is to highlight theadvantages of the combination of traditional Chinese and western medicine in the treatment of heart failure. Theusage of spironolactone, ACEI/ARB, beta blockers in our hospital was lower than the ratio reported, higher thanthat of the national average. However, the use of diureticis is lower than that of national average, which may relateto the use of damp-clearing herbs. Clinicians should pay attention to the high utilization rate of digoxin. Patientswith the left ventricular ejection fraction 〉 50% accounted for 61.1%, which required more attention should be paidto the diagnosis and treatment of patients with heart failure of the ejection fraction remains.
文摘Along with the development of biomedical ergigineering, negative pressure aspirator is more and more widely applied in clinical treatment and patients rescuing. The study of negative pressure aspi- rator is an important goal pursued in emergency treatment, became it can boost aid success. Given this need, this device based on MXT8051 single-chip is developed. The device can use Pulse Width Modulation (PWM) signal to drive the motor of negative pressure pump and it can adjust the motor's speed through the Proportional In- tegral Derivative (PID) algorithm to realize the setting negative pressure rapidly, aoctarately and stably. The control requiroemnt is accomplishedthrough the nmn-machine interface. This device has the advantage of simple operation, low cost and good practicability.
