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.

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.

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.

BACKGROUND:316L-Cu antibacterial stainless steel is made by adding a certain amount of copper into the stainless steel fol owed by a special heat treatment to uniformly disperse copper-rich precipitates in stainless steel substrate, thereby harvesting the antibacterial properties. OBJECTIVE:To evaluate the antibacterial activity of the Cu ions released from 316L type Cu-bearing antibacterial stainless steels against Porphyromonas gingivalis, thereby providing biomedical evidence for its clinical application. METHODS:The medical 316L stainless steel samples at a surface area to volume ratio of 0.1 cm2/L were soaked in simulated body fluids at 37 ℃ for 1-10 days. A graphite furnace atomic absorption spectrophotometer was employed to detect the amount of Cu release in the simulated body fluids each day and then the rate of Cu release per day could be determined. The antibacterial activities of the steel samples were evaluated by a standard film-covered method under a scanning electron microscope. RESULTS AND CONCLUSION:The daily Cu releasing amount from the 316L-Cu stainless steel within 10 days was significantly higher than that of 316L stainless steel, and al the values remained nearly constant. With time, the sterilizing rate of 316L-Cu stainless steel was gradual y increased, and reached 100%until the 10th hour. Porphyromonas gingivalis showed some morphological changes at 3 hours after treated with 316L-Cu stainless steel, appeared with cleavage at 6 hours, and mostly disintegrated into pieces at 9 hours. The results indicated that the 316L-Cu antibacterial stainless steel showed excel ent antibacterial property against Porphyromonas gingivalis, slowly release Cu irons, and alter the surrounding microenvironment, which is a highly promising biomaterial and has good clinical value.
