Objective To explore the clinical application of array comparative genomic hybridization (aCGH) and karyotype a-nalysis in the prenatal evaluation of fetal with small supernumerary marker chromosome (sSMC) .Methods One case was indenti-fied with de novo small supernumerary marker chromosome .G-banding analysis indicated that the fetus had a karyotype of 47 , XY ,+Mar .aCGH was used to define the precise location and size of de novo chromosome .Results aCGH revealed that there was 2 .03 Mb duplication from 15q11 .1-q11 .2 in the fetus .aCGH revealed the presence of small supernumerary marker chromosome . Conclusion The technologies of aCGH can be used for identifying the origin of small supernumerary marker chromosome and defi-ning the loci of the chromosome .Combined with the karyotype analysis ,it can be applied to genetics analysis and prenatal diagnosis .

Dysregulated cell cycle-mediated cell transformation and uncontrolled cell growth are some of the fundamental biolog-ical features of malignant tumors. Thus, understanding the mechanism(s) involved in the cell cycle will facilitate the discovery of the na-ture of tumor initiation and progression as well as the molecular mechanism of tumor malignancy. Consequently, biomarkers and drug targets for early diagnosis and treatment would be obtained. This study was designed to analyze in detail the key regulators of cell cycle and their importance in carcinogenesis and clinical prevention, diagnosis and treatment, and anti-cancer drug discovery. The biological impact of the dysregulated cell cycle on tumor occurrence and malignancy development is systematically described. The theoretical and practical significance of the cell cycle regulation in tumor diagnosis and therapy are also provided.

Objective To investigate the histopathology of liver,spleen and heart in mice model with Chlamydia pneumoniae ( C pneumoniae ) pneumonia Methods The Icr mice were inoculated with C pneumoniae ,strain CWL 029,by the intranasal or intravenous routes After a single inoculation,mice were killed on the 1st,3rd,7th,14th,21st,28th and 60th day separately Specimens of spleen,liver and heart were obtained from the acute stage of C pneumoniae pneumonitis and stained with hematoxylin eosin Results After inoculation of C pneumoniae ,there were infiltration of neutrophils and macrophages in the spleen and necrosis of hepatocytes The histopathology of iv inoculation group was more serious than that of intranasal inoculation group No pathology changes were observed in heart Conclusions After iv inoculation of C pneumoniae ,the histopathologic changes appeared in the tissue of liver and spleen correspondingly,and the changes were more serious than that of iv inoculation group This study demonstrated that C pneumoniae was mainly limited to lungs and dissemination of C pneumoniae was seldom

Objective To observe the clinical efficacy of cervus and cucumis polypeptide combined with Duhuo Jisheng Decoction Jiaji pain point injection in the treatment of lumbar intervertebral disc herniation. Methods Totally 68 cases of patients with lumbar intervertebral disc herniation were randomly divided into treatment group (34 cases) and control group (34 cases). Both groups were given Duhuo Jisheng Decoction orally besides basic treatment, and the treatment group received cervus and cucumis polypeptide Jiaji pain point injection additionally. Both groups were in a course of 10 days and treated for two courses. The clinical symptoms, visual analog pain scale (VAS), and Oswestry disability index (ODI) of the two groups were observed and compared among those before treatment, after one and two courses of treatment. Results Compared with the pretreatment of the same group, the VAS and ODI scores were lower after the first and second courses of treatment (P<0.05). After one and two course of treatment, VAS and ODI of the treatment group were lower than the control group (P<0.05, P<0.01). After one course of treatment, the total efficiency of treatment group was 91.2%(31/34), while the control group was 70.6%(24/34);after two courses, the total efficiency were respectively 100%(34/34) and 85.3%(29/34);the treatment group was better than control group during the same period (P<0.05). Conclusion Cervus and cucumis polypeptide combined with Duhuo Jisheng Decoction Jiaji pain point injection has good clinical efficacy in the treatment of lumbar intervertebral disc herniation.

Objective To investigate the clinical outcomes of arteriovenous anastomosis by microvascular anastomotic coupler device.Methods From January 2013 to November 2013,23 cases of microvascular anastomotic coupler device were applied in 18 patients with vascular injury of upper limb,and anastomosis time and patency rate was observed.Results In 18 patients,the brachial artery injury in 2 cases,the radial artery injury in 11 cases,the ulnar artery injury in 8 cases,the cephalic vein injury in 1 case,and basilic vein injury in 1 case.23 microvascular anastomotic coupler devices were applied in vascular injury.The post procedure vascular patency rate was 100％ and the average time of anastomosis was 3min 59s.Conclusion Microvascular anastomotic coupler device is charactered by higher patency rate and faster operation.It can not only be used in venous anastomosis of tissue graft,and also has a certain value in the repair of arteriovenous injury.

Objective To evaluate the efficacy of laparoscopic operations in the treatment of ectopic pregnancy.Methods A total of 148 cases of tubal pregnancy from January 2002 to January 2005 were studied.Laparoscopic operations included 106 cases of oviduct-sparing operation(79 cases of oviduct fenestration and 27 cases of lesion clearance),37 cases of salpingectomy,and 5 cases of lesion clearance.Results The diagnosis and operation were laparoscopically completed in all the 148 cases.Persistent ectopic pregnancy occurred in 2 cases.Postoperative monitoring of serum ?-hCG levels showed the shortest recovery time to normal levels after the treatment of salpingectomy(8?1 d),and the longest one after lesion clearance (15?2 d).Regular menstruation resumed at((31?)2 d) after salpingectomy and at(43?3 d) after lesion clearance.Follow-up checkups with uterotubography in 84 cases for 1~3 months(mean,2.3 months) found a patent rate of both oviducts of 82.1%(69/84).Conclusions Laparoscopic operations is a safe and effective option in the treatment of ectopic pregnancy.

Objective To study the effect of nutrition supports in aged mechanically ventilated patients fol-lowing thracic trauma. Methods 48 aged mechanically ventilated patients following thracic trauma were randomly divided into two groups,patients in treatment group( n = 24) received EEN and PN,control group( n = 24) only re-ceived TPN. Compared the nutritional index, time of mechanical ventilation and compared the complications such as windy,intestine paralysis, alimentary tract heorrhage, second heavy infection, hypohepatia and high blood glucose.Results The nutritional index between treatment group and control group had no statistical difference,but the time of mechanical ventilation and the ratio of the complications in control group were higher than that in-treatment group (P < 0.01). Conclusion EEN and PN can improve nutritional condition, have less complieations, promoting the pa-tient recovers form illness.
