With the development of screening and early diagnosis for breast cancer, the detected rote of ductal carcinoma in situ (DCIS) has increase markedly in recent decades. However, we know little about the biological potential of DCIS and its natural history. Controversy also exists with regard to the optimal management of DCIS.

Objective To analyze the correlation of serum hs‐CRP and IL‐6 levels with cerebral hemorrhage volume and nerve function damage .Methods One hundred and two cerebral hemor‐rhage patients served as an experimental group and 64 individuals undergoing physical examina‐tion served as a control group in this study .The patients in experimental group were further di‐vided into mild damage group (n= 29) ,moderate damage group (n= 42) ,severe damage group (n=31) ,10 ml hemorrhage group(n=15) ,10 -30 ml hemorrhage group (n=52) ,and >30 ml hemorrhage group (n=35) .Their serum hs‐CRP and IL‐6 levels were measured on days 1 ,5 ,10 and 15 after admission .Results The serum hs‐CRP and IL‐6 levels in experimental group in‐creased gradually in the first 5 days ,reached their peak on day 5 and then decreased gradually (P<0 .05) .The serum hs‐CRP and IL‐6 levels were significantly higher in severe damage group than in mild and moderate damage groups ( P<0 .05) ,and in experimental group than in control group (9 .46 ± 1 .26 mg/L vs 4 .24 ± 0 .94 mg/L ,P=0 .02) .Conclusion The serum hs‐CRP and IL‐6 levels are related with cerebral hemorrhage volume and nerve function damage ,and can thus be considered as an important parameter in clinical testing .

AIM:To research the chemical modification from berberine hydrochloride to berberrubine in Cortex Phellodendri before and after processing.METHODS:Berberrubine was isolated by column chromatography and the contents of berberine hydrochloride and berberrubine in different processed Cortex Phellodendri were determined by HPLC.RESULTS:With increacing processing temperature and time,part of berberine hydrochloride became berberrubine in processed Cortex Phellodendrin,and berberrubine content decreased under the condition of high temperature operation or overtime processing.CONCLUSION:The experimental data shows that the processed Cortex phellodendri has the maximum average content of berberrubine as processing temperature is maintained as 180℃ for 40 min.

In this paper, we present a 3D virtual phantom design software, which was developed based on object-oriented programming methodology and dedicated to medical physics research. This software was named Magical Phan tom (MPhantom), which is composed of 3D visual builder module and virtual CT scanner. The users can conveniently construct any complex 3D phantom, and then export the phantom as DICOM 3.0 CT images. MPhantom is a user-friendly and powerful software for 3D phantom configuration, and has passed the real scene's application test. MPhantom will accelerate the Monte Carlo simulation for dose calculation in radiation therapy and X ray imaging reconstruction algorithm research.

BACKGROUND:After peripheral nerve injury, to inhibit scar formation by drugs is the key to functional recovery. To reduce the amount of scar formation we designed a prednisolone-loaded film which can sustain drug release and good achievement in in vitro drug release test.
OBJECTIVE:To prepare the prednisolone implantable film and investigate its in vivo biocompatibility and safety.
METHODS:Prednisolone-loaded nanoparticles were first prepared with reverse micellar emulsion-solvent evaporation method, and the composite film and drug-loaded film were further prepared. Then, we investigated the in vivo biocompatibility of drug-loaded film through celltoxicity test, hemolysis test, acute systemic toxicity test, chronic systemic toxicity test.
RESULTS AND CONCLUSION:After cultured for 7 days, the relative growth rate of L929 mouse fibroblasts was 92.6%, showing no cytotoxicity. The hemolysis rate of the film was 0.59%, indicating that the material had no hemolysis action. No abnormal biological behaviors were seen in mice after intraperitoneal injection of film extracts, and there were no changes in liver and renal functions in rats. As il ustrated above, we can safely come to a conclusion that prednisolone-loaded film possesses good biocompatibility and can be safely used in the experiment of reducing the scar at sites of peripheral nerve repair.

Objective:To investigate the pathogenic bacteria distribution and risk factors of pulmonary infection after tracheotomy in patients with stroke coma,and to put forward preventive measures.Methods:96 patients with stroke coma from January 2016 to February 2017 in our hospital were retrospectively analyzed.The incidence of pulmonary infection and distribution of pathogenic bacteria of patients with stroke coma were analyzed.At the same time,the risk factors of pulmonary infection were analyzed by single factor and multiple factors logistic regression analysis,and corresponding preventive measures were put forward.Results:The incidence of pulmonary infection after tracheotomy in 96 patients with stroke coma was 48.96％ (47/96).A total of 104 pathogens were isolated and cultured,including gram negative bacteria 69 strains (66.35％),gram positive bacteria 20 strains (19.23％) and fungus 15 strains (14.42％).Single factor regression analysis results showed that pulmonary infection after tracheotomy in patients with stroke coma was closely related with age,basic diseases,time of tracheotomy,and bed time,use of broad-spectrum antibiotics,smoking history,artificial airway,times of sputum suction and inhalation(P＜0.05),and it was not related to the patient's gender,weight,stroke type (P＞0.05).Multivariate logistic regression analysis showed that age 45 years old,complicated with basic disease,time oftracheotomy 5 d,use of broad-spectrum antibiotics,smoking history and the establishment of artificial airway were risk factors of pulmonary infection after tmcheotomy in patients with stroke coma (P＜0.05).ROC analysis results showed that the critical point (threshold C) oftmcheotomy time was 4.3 days,and the sensitivity and specificity were 0.851 and 0.918 respectively.Conclusion:The main pathogenic bacteria of pulmonary infection after tracheotomy in patients with stroke coma is gram-negative bacteria,age 45 years old,complicated with basic disease,time of tmcheotomy 5d,use of broad-spectrum antibiotics,smoking history and the establishment of artificial airway can lead to pulmonary infection after tracheotomy in patients with stroke coma,and the risk of pulmonary infection in patients with stroke coma will increase considerably after the time of tracheotomy for more than 4.3 days.Targeted measures should be taken to reduce the risk of pulmonary infection according to pathogenic features and risk factors.
