Pain is a subjective and emotional experience associated with tissue injury.Surgery can cause pain.The pain will cause sympathetic excitement,stress response,impact on circulation,respiration and neuroendocrine system,and increase heart rate,blood pressure and oxygen consumption.Pain is detrimental to cough and that can lead to atelectasis and hypoxemia because of airway secretions aggregation.Those are very unfavorable for children with congenital heart disease complicated with postoperative low cardiac output syndrome.In addition,there are greater stress response after congenital heart disease due to the operation and the cardiopulmonary bypass,so more attention should be payed to the postoperative pain.

The effect of extraction and nonextraction treatment on the soft tissue profile of the subjects borderline Angle classⅡ division 1 malocclusion is concerned mainly by orthodontists.This article reviewes the effect of extraction and nonextraction treatment on the soft tissue profile of the subjects with Angle classⅡ division 1 borderline patients and the important factors(such as differences between the types of tooth extraction and growth).The aim is to guide clinic diagnosis and treatment for borderline Angle classⅡ division 1 malocclusion.

Rheumatoid diseases (RD) are a group of diseases affecting bones,joints,and the surrounding soft tissues,such as muscle,synovial membrane,tendons,fascia,nervus.The etiology and pathogenesis are complicated.Since most RD are systemic diseases,traditional imaging techniques have limited value for the diagnosis and treatment monitoring of RD.18F-FDG PET/CT can display morphologic and metabolic information simultaneously,and is considered as a potential tool for the diagnosis of RD.This review summarizes the application of 18F-FDG PET/CT in RD,such as systemic vasculitis,relapsing polychondritis and rheumatoid arthritis.

Objective To evaluate the value of echocardiography in the diagnosis of truncus arteriosus communis(TAC)and associated intracardiac malformations. Methods We retrospectively reviewed 30 patients with TAC, their datum of clinical and echocardiographic diagnosis were studied during the period of January 2006 to May 2014 in Shengjing Hospital Affiliated to China Medical University. Results Based on Collet Edwards method, these 30 TAC patients included 10 cases of typeⅠ, 7 cases of typeⅡ, 5 cases of typeⅢ, 8 cases of typeⅣ. The most common associated intracardiac malformation was ventricular septal defect in 24 cases, 16 cases had arterial septal defect, 7 cases had patent ductus arteriosus, 6 cases had single ventricle, 3 cases had right aortic arch, etc. Among them, 8 cases were confirmed by surgery, 5 cases of typeⅠ, 3 cases of typeⅡ, and 1 case of typeⅠdied after operation;16 cases were confirmed by CT angiography (CTA) examinations, all of them died without operation within 6 months. Conclusion Echocardiography is a preferred and non-invasive method for TAC and the intracardiac malformations.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

This paper is aimed to provide the methods of quality control and bioassay of traditional Chinese medicine injections including bioassay method. Shuanghuanglian freeze-dried powder for injection (SFPI) was chosen as study object. HPLC-ELSD fingerprints of SFPI had been established and the samples were differentiated by similarity calculation. Meanwhile, biological profiles of SFPI on Escherichia coli had been established by microcalorimetry. The similarity values were calculated using the correlation coefficient, based on quantitative thermo-kinetic parameters (T2m, Tj, I%). The results indicated that HPLC-ELSD fingerprints, which showed content changes of chemical components, could not monitor minimal variation of different samples, especially that of biological pollutants, while biological profiles could sensitively detect antibiotic activity alterations of the samples, which were kept under specific conditions. In conclusion, characterized by two-dimension, microcalorimetry could supply thermograms as biological profiles characterized to describe the bioactivity of drugs. This study could clearly demonstrate that the correlative detection was proposed as an efficient strategy for quality control of SFPI, based on HPLC-ELSD fingerprints and biological profiles, which could detect quality fluctuation of samples early and quickly and predict the potential adverse drug events (ADE) for ensuring clinical safety.

Objective To evaluate transoral Orvil EEA stapler (OrVil) procedure in laparoscopic total gastrectomy for cardiac carcinoma compared with conventional anvil head method (purse-string suture).Methods From May 2014 to December 2014 20 cases were included into OrVil group,and 25 cases into purse-string suture group.Results The two groups had similar mean numbers of dissected lymph nodes [(25 ± 3) vs.(24 ± 4),t =1.067,P =0.292],the mean time of operation,intraoperative blood loss,and postoperative complications (5 vs.6,P =0.938).The length of incision was significantly shorter [(5 ±1) cm vs.(11 ± 2) cm,t =-10.724,P ＜ 0.0l] and the esophagojejunostomy time was significantly less [(28 ± 4) min vs.(39 ± 5) min,t =-7.996,P ＜ 0.01] with the use of OrVil.The time to first flatus and postoperative hospital stay were (3.7 ± 0.9) d vs.(4.4 ± 1.0) d,t =-2.485,P =0.017 and (13 ± 5) d vs.(16 ±4) d,t =-2.184,P =0.035.Conclusions OrVil is a technically safe and feasible surgical procedure for esophagojejunostomy in laparoscopy assisted total gastrectomy in the treatment of cardiac carcinoma.

Objective To observe the blood flow changes of left ventricular cavity and quantify the energy loss (EL) and circulation of left ventricular during systole and diastole in patients with dilated cardiomyopathy(DCM) via vector flow mapping(VFM).Methods Thirty-six healthy volunteers and 32DCM patients were enrolled.According to the severity of mitral regurgitation(MR),DCM patients were divided into two groups.The quantitative parameters,including average energy loss(EL-base,EL mid,EL-apex) and circulation (vortex quantity,vortex area,circulation) were measured in the different periods of VFM imaging mode in apical four-chamber view,apical three-chamber view and apical two-chamber view respectively.The difference of parameters was evaluated between different groups during the different periods.The early transmitral valve blood flow velocity E,the late transmitral valve blood flow velocity A,the ratio of early transmitral valve blood flow velocity to the early diastolic mitral valve velocity E/e,the ratio of early transmitral valve blood flow velocity to the late transmitral valve blood flow velocity E/A and Tei index were derived via dual-Doppler imaging technology.Meanwhile,the correlation between VFM parameters with E,A,E/A,E/e or Tei index was also analyzed.Results ①The level of EL were decreased significantly among EL-mid and EL-apex during early diastole,EL-mid during mid-systole,EL-mid and EL-apex during late-systole (P ＜0.05),when compared with the control group.The vortex quantity,vortex area and circulation during early diastole and the vortex area and circulation during atrial contraction period were significantly different between two groups (all P ＜ 0.05).As for mid-diastole,only vortex area showed significant difference (P ＜0).01).(②) When compared with different grades of MR in DCM patients,the level of all segments EL during diastole and EL-base during systole increased with severity of MR(P ＜0.05).The circulation during diastole also increased with the severity of MR(P ＜0.05).③The vortex area and circulation had positive correlation with E/e during diastole in all subjects(all P ＜0.05).The vortex area during atrial contraction period and early diastole had positive correlation with E/A and Tei index in all subjects(r =0.630,0.345,0.468,0.316,0.663,0.264,respectively,allP ＜0.01).EL-mid during late-systole were negatively correlated with LV end diastolic volume,end systolic volume,but positively correlated with ejection fraction in all subjects(r =0.335,-0.312,0.340,respectively,all P ＜0.05).While,there was positive correlation between E/A with the basal segment of mid-diastole(r =0.376,P ＜0.01).Conclusions The visualization of hydromechanics inside the heart of DCM patients could be directly accomplished by VFM,which can provide a new method for diagnosis and evaluation of DCM.
