Objective To construct an expression vector containing esp1 in order to observe the effect of esp1 gene on the apoptosis of A549 cells. Methods A conditional plasmid vector containing esp1 was constructed, and transfected into A549 cells. The expression level of esp1 was detected by fluorescence microscopy, the chromosomes and the apoptosis, proliferation were detected. Results Transfection of IRE-EGFP-esp1 into A549 cells reduced improper chromosome segregation, cell proliferation and increased the apoptosis of A549 cells. Conclusion Up-regulation of esp1 not only has inhibitory effects on the abnormal proliferation and chromatid separation of tumor cells, but induces the apoptosis of A549 cells.

The Seedcoat structure of Cuscuta L. was damaged by treating the seed with various organic solvents or concentrated sulfuric acid for different durations of time or by mechanicalmethods. It was found that the surface layer and hilum were erosion-nonresistant; the palisades had orderly arranged thick cell walls and contain phenols. They are th e main barrier controlling the entrance of water through seedcoat. Erosions with concentrated sulfuric acid are effective methods for overcoming its impermeability and raisiug germination capacity of seeds.

Objective To build clinical nursing pathway for artificial abortion operation and explore the effect of this method. Methods The nursing pathway was designed and carried out. The satisfaction degree with nursing, status of patients' awareness about contraception and artificial abortion operation was compared before and after the nursing pathway was implemented. Results Before and after the nursing pathway was implemented,the proportion of missing item of operation record was 0.636 and 0.013, the satisfaction degree with nursing was 77.0% and 92.3%, rate of patients' awareness about contraception and artificial abortion operation was 47.6% and 96.1%. Conclusions The clinical nursing pathway for artificial abortion operation may improve the degree of satisfaction- and the status of patients' awareness about contraception and artificial abortion operation, and decline the proportion of missing item of operation note, it ensures high nursing quality and safety surgery, which is worthy of popularizing.

Objective: To ascertain the process condition of extraction Mashi Granules(Herba Ephedrae, Gypsum Fibrosum, Radix Puerariae, Herba Methal, Semen Armeniacae Amerum, etc.) Methods: In combination with area under the curve of hypothermy in rabbits, process water, macerating time and boiling times were used as parameters in uniformidy design. And then appropriate excipients were selected on the basis of hygroscopicity and granulation. Results: 20 times amount of water as much as herbs was added, macerating time reached as far as 40 min, and extracted 3 times, 2h a time. Excipient formula consisted of lactose and mannitol(4∶1, w/w). Conclusion: The experimental results provide the basis for the ascertainment of extracting process and formulation of Mashi Granules.

In recent years,the United States analyzing the aging of the population brought by the increase in cardiovascular diseases such as medical equipment and its impact on the U.S. market-oriented role,combined with the present condition of population and medical device market of China,the trend of aging is pointed out and that there is a great potential market of medical device for cardiovascular disease in China,but some problems still exist,such as high price,low public acceptance,etc. According to relevant policies,corresponding suggestions were proposed for domestic medical device companies to enhance their R&D capability and adaptability to the medical system reform.

Objective To compare magnetic resonance spectroscopy (MRS) characteristics and changes before and after 5-Fu interventional thermochemotherapy (ITC) as well as to analyze the correlation of Cho/Lip and apoptosis index (AI) in hepatic VX2 carcinoma animal model.Methods 20 rabbit models of hepatic VX2 carcinoma were implanted successfully.Ten days later,as tumor diameter≥ 10 mm,routine scan and 1H-MRS were performed before one day and after 14 days on all of rabbits by Philips 1.5T MR scanner.The changes of Cho peak,Lip peak and the ratio of Cho/Lip before and after the treatment were analyzed.Specimens of AI were examined and compared with the ratio of Cho/Lip.Results The Cho peak and Lip peak were increased before ITC.After ITC,the Cho peak and the ratio of Cho/Lip decreased than before.The Lip peak was further increased than that of before.AI was correlated negatively with the ratio of Cho/Lip (r =-0.56,P =0.02).Conclusions The metabolites of different ROI are matched with the levels and scopes of AI.1H-MRS can be used to evaluate tumor cell apoptosis and energy metabolism changes of the rabbit models of hepatic VX2 carcinoma with the treatment.

Objective To evaluate the incidence and epidemiologic characteristics of Kawasaki disease (KD)in Nanjing.Methods We reviewed the medical records and reports of all patients admitted to Nanjing Chil-dren′Hospital with KD diagnosed during 3 -year periods from 2012 to 2014.Results We studied 1 446 inpatients diagnosed with KD from 2012 to 2014.There were 1 135 cases(78.5%)with complete KD.The ratio of male to female was 1.7241.The disease occurred in all of the seasons,but the peak was from spring to summer.Age at onset ranged from 1 month to 14 years old,and the peak age group was 1 year old.Fever(99.45%)was the most common clinical symptom,followed by conjunctive congestion(93.15%),rash(73.32%),oral changes(51.76%), extremities desquamate(75.08%)and lymphadenopathy(45.89%).There were 131(9.05%)patients with coronary aneurysm,the ratio of male to female was 3.02  1.14 patients (0.97%)developed recurrent KD.Conclusion Patients with KD has become more and more in Nanjing,and clinical doctors should improve the understanding of KD. Early diagnosis and treatment is very important to reduce the sequelae and reduce the mortality of KD.

A multi-channel central monitoring system based on B/S mode is designed. It is consistent of the central monitoring server software, the Internet Explorer in the client PC, and a physiological signal collector. The server software can accept two client's request of data transfer, and real-time monitor several patients through Internet. The client uses the B/S mode, and just need to install an ActiveX control. The only thing users should to do is opening the Intemet Explorer, from which the waveform and signals are shown and transferred. The system extends the central monitoring service from hospital to the community, and is benefit for patient's long-term observation and cutting fees. Additionally, it can be a new solution of network based health care devices.

Objective:To investigate the inhibitory effect of Dickkopf-1 (Dkk1) on vasculogenic mimicry (VM) formation and the relevant mechanism. Methods:CD34-PAS dual staining and immunohistochemical staining were used to detect and analyze the re-lationship between VM existence and Dkk1 expression in 217 human colon cancer tissue samples;three dimensional (3D) culture was used to detect the influence of Dkk1 on tube structure formation and on VE-cadherin expression;a subcutaneous mouse xenograft mod-el was made to further validate the inhibitory role of Dkk1 on VM formation in vivo. Results:VM-positive samples indicated a lower expression of Dkk1(P<0.05);colon cancer cells with Dkk1 overexpression exhibited a decreased ability to form tube-like structure and a decreased expression of VE-cadherin;Dkk1 inhibited the VM-formation abilities of human colorectal carcinoma cell line xenograft tu-mor tissue. Conclusion:Dkk1 inhibits the VM formation of colon cancer.
