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 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 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.

Objective To observe the change characteristics of serum prealbumin and cholinesterase in the liver cirrhosis pa-tients ,and to discusses the determination of these two indicators in diagnosis ,treatment and prognosis of clinical significance in pa-tients with liver cirrhosis .Methods A total of 45 liver cirrhosis patients diagnosis in our hospital from July to December 2013 were recruited into study group ,at the same time 98 healthy people were recruited into control group .The Hitachi 7170 automatic bio-chemical analyzer was used to detected serum prealbumin and cholinesterase ,the former was detected by immunoturbidimetry meth-od ,the latter was detected by butyryl glucosinolates choline bottom method .The levels and abnormal rates of the two indicators be-fore and after treatment in the study group were compared with those of the control group .Results The serum prealbumin and cho-linesterase at different stage in the study group were significant lower than those of the control group(P<0 .05) .The abnormal rate of serum prealbumin after treatment was significant different with those among and before treatment in patients with cirrhosis (χ2 =10 .08 ,P<0 .05) ,but there were no significant difference on cholinesterase(P>0 .05) .Conclusion The serum prealbumin is a sensitive indicator of liver cell damage ,its change could reflect the condition of treatment and development status ,which has im-portant clinical significance on judging the prognosis of patients with liver cirrhosis .

Objective To study the predictive value of HER2/neu amplification and lymphovascular invasion for axillary lymph node metastasis in T1 breast cancer patients(mass<2 cm).Methods Reviewed the medical record of 206 T1 breast cancer patients who were the presence or absence of lymph node metastasis with IHC and FISH,analyzed the association be-tween ALNM and various clinicopathological predictive factors such as age,tumor size (T1a,T1b,T1c),multiplicity,the his-tologic grade,the nuclear grade,the presence of lymphovascular invasion (LVI),the estrogen and progesterone receptor sta-tus,an HER2/neu expression,the Ki-67 labeling index and the bcl-2 expression,and discussed the correlation of the various factors with axillary lymph node metastasis of T1 breast cancer.Results One hundred and thirty-nine were the node nega-tive group (T1N0)and the remaining 67 cases were allotted to the node positive group (T1N1-3),age (χ2 = 6.484,P =0.011),LVI (χ2 =72.813,P <0.001),histologic grade (χ2 =74.813,P =0.019),HER2/neu (χ2 =74.813,P <0.005),Ki-67 (χ2 =6.255,P =0.012)and bcl-2 (χ2 =4.977,P =0.026)were the statistically significant predictive factors related to node metastasis.The factors such as tumor size (χ2 =1.544,P =0.254),surgical method (χ2 =2.414,P =2.414),and ucle-ar grading HG (χ2 =2.017,P =0.159),estrogen receptors ER (χ2 =0.140,P =0.709),progesterone receptor PgR (χ2 =2.199,P =2.199),have no significant statistical correlation with early breast cancer lymph node metastasis.Conclusion HER2/neu overexpression and LVI were related to the increased incidence of ALNM in T1 breast cancer patients,LVI was the most predictive factor of ALNM.
