Objective: To investigate the biological basis of qi, blood and vessel in immune thrombocytopenia(ITP) patients with syndrome of qi failing to govern blood(SQFGB) based on traditional Chinese medicine.Methods: A total of 52 ITP patients with SQFCB were enrolled and divided into bleeding group(38 cases) and non-bleeding group(14 cases).Bleeding group was further divided into mild qi deficiency group(25 cases) and moderate/severe qi deficiency group(13 cases) based on Chinese Medicine syndrome score.20 healthy volunteer were recruited as control group.The count of platelet(PLT) was taken as the blood related indicator.The expressions of cytokines including IL-1β, IL-17 A, TNF-α, CD40 L, and TGF-β, detected by Aim Plex Multiple Immunoassays for Flow, were taken as the qi related indicators.The expressions of VEGF-A, detected by Aim Plex Multiple Immunoassays for Flow and NO, NOS, and ET-1 detected by ELISA, were taken as the vessel related indicators.Results: As compared to the control group, the count of PLT, taken as the blood related indicator, was significantly lower in ITP group patients with SQFCB(P<0.05).The expression levels of IL-17 A and TNF-α, taken as the qi related indicators, were significantly higher, while those of CD40 L, IL-1β, and TGF-β, also taken as the qi related indicators, were significantly lower in ITP patients with SQFCB, respectively(P<0.05).The expression levels of NO and ET-1, taken as the vessel related indicators, were significantly higher, while the expression levels of NOS and VEGF-A also taken as the vessel related indicators, were significantly lower in ITP patients with SQFCB, respectively(P<0.05).The count of PLT, taken as the blood related indicator, was significantly lower in moderate/severe group than those in mild group(P<0.05).The expression levels of CD40 L and TGF-β, taken as the qi related indicators, were also significantly lower in moderate/severe group than those in mild group, respectively(P<0.05).Conclusion: The count of PLT might be the biological basis of blood.The expressions of NO, NOS, ET-1 and VEGF-A might be the biological basis of vessel.The expressions of IL-1β, IL-17 A, TNF-α, TGF-β, and CD40 L may be the biological basis of qi.The expressions of CD40 L and TGF-β could reflect the degree of qi deficiency in ITP patients based on the theory of qi and blood. 展开更多

In this editorial,I present my comments on the article by Solarino et al.Conversion hip arthroplasty,which is an optional salvage procedure performed following unsuccessful fixation of intertrochanteric femur fractures in elderly pati-ents,entails more complex processes and higher rates of operative complications than primary arthroplasty.Hence,it is important to consider the appropriateness of the primary treatment choice,as well as the adequacy of nailing fixation for intertrochanteric fractures.This article briefly analyzes the possible factors contributing to the nailing failure of intertrochanteric fractures and attempts to find corresponding countermeasures to prevent fixation failures.It also analyzes the choice of treatment between nailing fixation and primary arthroplasty for intertrochanteric fractures. 展开更多

An exact forecast of the failures of a sucker rod-pumped well in a production area means much for an oilfield’s operation budget, operational arrangement and production plan. In this paper, according to the characteristics of failed sucker rod-pumped well randomness and strong outburst, with the gray GM (1,1) forecast model and the Markov forecast model combined, gray GM (1,1) forecast model is utilized to handle the primary data of an oilfield, and Markov forecast model is utilized to calculate the state transfer probability of forecast value. Then, the gray Markov forecast model considering the influence of randomness factors is formed. Field results prove that the calculation precision of this method is higher and the practicability is greater. 展开更多

Patel ar instability is a common clinical problem encountered by orthopedic surgeons specializing in the knee. For patients with chronic lateral patellar instability, the standard surgical approach is to stabilize the patella through a medial patellofemoral ligament(MPFL) reconstruction. Foreseeably, an increasing number of revision surgeries of the reconstructed MPFL will be seen in upcoming years. In this paper, the causes of failed MPFL reconstruction are analyzed:(1) incorrect surgical indication or inappropriate surgical technique/patient selection;(2) a technical error; and(3) an incorrect assessment of the concomitant risk factors for instability. An understanding of the anatomy and biomechanics of the MPFL and cautiousness with the imaging techniques while favoring clinical over radiological findings and the use of common sense to determine the adequate surgical technique for each particular case, are critical to minimizing MPFL surgery failure. Additionally, our approach to dealing with failure after primary MPFL reconstruction is also presented. 展开更多

AIM: Prospective evaluation of repeat endoscopic retrograde cholangiopancreatography (ERCP) for failed Schutz grade 1 biliary cannulation in a high-volume center. METHODS: Prospective intention-to-treat analysis of patients referred for biliary cannulation following recent unsuccessful ERCP. RESULTS: Fifty-one patients (35 female; mean age: 62.5 years; age range: 40-87 years) with previous failed biliary cannulation were referred for repeat ERCP. The indication for ERCP was primarily choledocholithiasis (45%) or pancreatic malignancy (18%). Successful biliary can- nulation was 100%. The precut needle knife sphincterotomy (NKS) rate was 27.4%. Complications occurred in 3.9% (post-ERCP pancreatitis). An identif iable reason for initial unsuccessful biliary cannulation was present in 55% of cases. Compared to a cohort of 940 nave pa-pilla patients (female 61%; mean age: 59.9 years; age range: 18-94 years) who required sphincterotomy over the same time period, there was no statistical difference in the cannulation success rate (100% vs 98%) or postERCP pancreatitis (3.1% vs 3.9%). Precut NKS use was more frequent (27.4% vs 12.7%) (P = 0.017). CONCLUSION: Referral to a high-volume center following unsuccessful ERCP is associated with high technical success, with a favorable complication rate, compared to routine ERCP procedures. 展开更多

AIM: To study the institutional experience over 8 years with 200 continuous-flow(CF)- left ventricular assist devices(LVAD).METHODS: We evaluated our institution's LVAD database and analyzed all patients who received a CF LVAD as a bridge to transplant(BTT) or destination therapy from March 2006 until June 2014. We identified 200 patients, of which 179 were implanted with a Heart Mate II device(Thoratec Corp., Pleasanton, CA) and 21 received a Heartware HVAD(Heart Ware Inc., Framingham, MA).RESULTS: The mean age of our LVAD recipients was 59.3 years(range 17-81), 76%(152/200) were males, and 49% were implanted for the indication of BTT. The survival rate for our LVAD patients at 30 d, 6 mo, 12 mo, 2 years, 3 years, and 4 years was 94%, 86%, 78%, 71%, 62% and 45% respectively. The mean duration of LVAD support was 581 d(range 2-2595 d). Gastrointestinal bleeding(was the most common adverse event(43/200, 21%), followed by right ventricular failure(38/200, 19%), stroke(31/200, 15%), re exploration for bleeding(31/200, 15%),ventilator dependent respiratory failure(19/200, 9%) and pneumonia(15/200, 7%). Our driveline infection rate was 7%. Pump thrombosis occurred in 6% of patients. Device exchanged was needed in 6% of patients. On multivariate analysis, preoperative liver dysfunction, ventilator dependent respiratory failure, tracheostomy and right ventricular failure requiring right ventricular assist device support were significant predictors of post LVAD survival.CONCLUSION: Short and long term survival for patients on LVAD support are excellent, although outcomes still remain inferior compared to heart transplantation. The incidence of driveline infections, pump thrombosis and pump exchange have declined significantly in recent years. 展开更多

The changes after treatment were ob-served chiefly by electromyography while sensory and motor improvement were also re-corded as auxiliary indicators. The therapeutic results in the acupuncture group were 5 cases cured, 26 markedly effective, 19 unproved, and 4 cases failed, a total effective rate of 92.6% in contrast to the 55.6% for the controls. Analysis of the therapeutic results showed that 1) those in the acupuncture group were significantly better than in the control group; 2) nerve injuries should be treated as early as possible; 3) the radial nerve and the common peroneal nerve recovered faster than others; 4) cases not surgically explored recovered faster than those that were, and 5) patients with prompt propagation of the needling sensation recovered significantly faster than those with slow propagation. 展开更多

Changes in the way new drugs are tested appear to be necessary. Three changes are presented here and will be discussed. The first change is that Alzheimer's disease must be considered a disease of four major pathological processes, not one. The four processes are: 1) vascular hy- poperfusion of the brain with associated mitochondrial dysfunction, 2) destructive protein inclusions, 3) uncontrolled oxidative stress, and 4) proinflammatory immune processes second- ary to microglial and astrocytic dysfunction in the brain. The second change recommended is to alter the standard cognitive measurement tools used to quantify mental decline in test patients. Specifically the Dementia Severity Rating Scale (DSRS) should supersede Mini-Mental State Examination (MMSE) and other popular tests, and a measurement scale developed in research should be used to produce a linear and non-irregular baseline. Finally, accepting the concept that four etiologies cause Alzheimer's disease leads to the last necessary change, that new thera- pies must be employed directed against all four causes, likely as a combination. There are drugs ready to be employed in such a combinations which are available and used clinically for other purposes so can be used "offlabel" and one such combination is suggested. 展开更多

In the construction of the filling gob-side entry retaining in a lane, we utilize the self-slide natural phenomenon of a falling gangue in an inclined coal seam goaf. First, we put the falling gangue of goal above the laneway and made it the main filling material by adopting the measurement of flexible supporting system combined with those of rigid supporting system. Then we made the filling material gunited and solidified to maintain the filling goal of the gob-side entry retaining beside the lane. Considering the law of energy conservation and law of pressure distribution for retaining the active and Static soil of the wall, we analyzed the reliability of a gangue blocking facilities and the stability of the filling mate- rial in the lane. We analyze the figures to see the stability. The result shows that the gangue block sup- porting system is reliable, and has been successfully practically applied. 展开更多

For high reliability and long life systems, system pass/fail data are often rare. Integrating lower-level data, such as data drawn from the subsystem or component pass/fail testing,the Bayesian analysis can improve the precision of the system reliability assessment. If the multi-level pass/fail data are overlapping,one challenging problem for the Bayesian analysis is to develop a likelihood function. Since the computation burden of the existing methods makes them infeasible for multi-component systems, this paper proposes an improved Bayesian approach for the system reliability assessment in light of overlapping data. This approach includes three steps: fristly searching for feasible paths based on the binary decision diagram, then screening feasible points based on space partition and constraint decomposition, and finally simplifying the likelihood function. An example of a satellite rolling control system demonstrates the feasibility and the efficiency of the proposed approach. 展开更多
