OBJECTIVETo explore the value of a novel prenatal diagnosis model using combined chromosomal karyotyping and BACs-on-Beads(BoBs), a newly-developed technique.

METHODS1048 single pregnancy pregnant women with various diagnostic indications were performed amniocentesis for prenatal diagnosis with karyotyping and BoBs simultaneously.

RESULTSAmong 1047 successfully cultured specimens, 50 chromosomal abnormalities were identified with BoBs, including 43 common chromosomal trisomies, 3 chimeric chromosomes and 4 structural abnormalities, of which 3 microdeletions/microduplications were not detected with karyotyping. Except for extra yield of 1 Robertsonian translocation, the other numerical chromosomal abnormalities were detected with both karyotyping and BoBs. Ten fetal chromosome abnormalities were confirmed with karyotyping, including 8 structural abnormalities and 2 chimeric chromosomes.

CONCLUSIONCombination of karyotyping and BoBs turned out to be a rapid, complementary and effective diagnostic model for fetal chromosomal abnormalities and microdeletion syndromes, which could yield a higher detection rate of fetal chromosomal abnormalities and chromosomal microdeletions/microduplications.

BACKGROUNDDaxx has been identified as a nuclear protein that involves in apoptosis and transcriptional repression. Daxx co-localizes with the promyelocytic leukemia (PML) protein and regulates transcription. Human Daxx (hDaxx) is a protein that functions as a transcriptional regulation through its interaction with some DNA-associated proteins. The aim of this study was to explore the transcriptional regulatory effect of hDaxx interacting with adenovirus (Ad) 12 E1B (Ad12E1B) 55-kDa oncoprotein.

METHODSThe co-localization of hDaxx-Ad12E1B or hDaxx-PML protein in the nucleus was observed under a confocal microscope. Interaction of hDaxx and Ad12E1B was analyzed by yeast two-hybrid assay. Direct binding of hDaxx and Ad12E1B was analyzed using coimmunoprecipitation and Western blot in vivo and in vitro. The activity of a luciferase reporter gene, which was regulated by an hDaxx modulated thymidine kinase (TK) promoter, was detected in an automat luminometer.

RESULTSAd12E1B, which co-localized with hDaxx in the nuclei of G401-CC3 cells, disrupted the co-localization of hDaxx and PML in the PML oncogenic domains (PODs). hDaxx bound directly to Ad12E1B in vivo and in vitro. hDaxx interacted with Ad12E1B along its full length. Ad12E1B enhanced transcriptional repression activity of hDaxx.

CONCLUSIONAd12E1B disrupts the co-localization of hDaxx with PML in PODs and enhances transcriptional repression activity of hDaxx.

Objective To evaluate the appearance of CT in patients with severe acute respiratory syndrome (SARS) in the recovery phase, and to study the correlation of CT findings with pulmonary function.Methods From June to August in 2003, 100 patient with confirmed SARS accepted examination in our hospital. Among them, 91 patients (39 men, 52 women, mean age 36.4 years, age range 19- 66 years) received CT examination and pulmonary function test on the same day. The interval between SARS onset and the examination ranged from 52 to 125 days (mean 87.4 days). CT appearances of pulmonary parenchymal abnormalities including distribution and extent of involvement were quantitatively analyzed, and four levels on CT scan including the aortic arch, the tracheal carina, the pulmonary venous confluence, and the dome of right diaphragm were selected to score the lesions. The correlation of CT scores with the results of pulmonary function tests was studied.Results Of the 91 cases, 47 patients had normal CT appearance in the recovery phase, whereas the other 44 patients still had parenchymal abnormalities, including residual ground-glass opacification and reticular shadow. CT visual score had correlation with DLco% ( r =-0.618, P

Objective To explore the value of BACs-on-BeadsTM(BoBs)technique in detection of chromosome microdeletions/microduplications.Methods Samples for detection included 1 486 amniotic fluid samples for prenatal diagnosis and 7 peripheral blood samples with suspected chromosome microdeletions/microduplications collected in Zibo Maternal and Child Health Hospital from March 2015 to January 2017.BoBs and karyotyping were performed for all samples and SNP arrays were carried out to confirm the positive results of BoBs.Results 1 case of DiGeorge syndrome, 3cases of 22q11 microduplication syndrome,and 3 cases of Williams-Beuren syndrome were detected by BoBs,among which 1 case of Williams-Beuren syndromewas detected from peripheral blood and the rest were detected from amniotic fluid samples of high-risk gravidas after serological screening.None of the above 7 cases with chromosome microdeletion/microduplication syndromes was detected by karyotyping,butall of them were identified by SNP arrays.Conclusion BoBstechnique is capable of detecting specific chromosome microdeletions/microduplications with high accuracy and efficiency, which couldbe an auxiliary diagnostic tool for fetal chromosome abnormalities in addition to karyotyping.

Objective To observe the effect of two kinds of Kinesio taping methods on shoulder pain in hemiplegic patients with stroke during spasm period. Methods From October,2015 to September,2017,75 stroke hemiplegic patients with shoulder pain during spasm period were randomly divided into group A(n=25),group B(n=25)and control group(n=25).Three groups were given conventional treatment,and group A and group B received two kinds of Kinesio taping methods,respectively.Be-fore and four weeks after treatment,the shoulder pain was assessed with Visual Analogue Scale(VAS),the motor function of upper limb was assessed with Fugl-Meyer Assessment(FMA),and their activities of daily living was assessed with modified Barthel Index(MBI). Results After treatment, the score of VAS significantly decreased in all groups (P<0.001), and was lower in groups A and B than in the control group(P<0.05),especially in group A(P<0.01);the scores of FMA and MBI signifi-cantly increased(P<0.001),and was higher in groups A and B than in the control group(P<0.05),especially in group A(P<0.05). Conclusion Kinesio taping combined with rehabilitation training for the treatment of stroke patients following hemiple-gia during spasm period can relieve the shoulder pain and improve the motor function of upper limb and activi-ties of daily living.The curative effect varies with different taping methods.

Objective To summarize the experience in laparoscopic spleen-preserving distal panereatectomy.Methods From Nov 2003 to July 2006,six patients with distal pancreatic cystic lesions underwent laparoscopic spleen-preserving distal pancreatectomy with splenic vessels preservation. Results All operations were successful with the operative time ranging from 140～265 min and the intraoperative blood loss ranged from 350～600 ml.One case received combination resection of right adrenal adenoma,1 case with combined laparoscopic myomectomy and left ovarian teratomeetamy,1 case with combined laparoscopic myomectomy,1 case with combined laparoscopic cholecysteetomy.All patients were discharged 4 to 9 days postoperatively.The pathologic diagnosis was retained cyst in 2 cases,serous cystadenoma in 2 cases,mucious cystadenoma in 2 cases.Symptoms disappeared in all cases after operations and there was no recurrence during a follow-up period that ranged from 1 month to 31 months.Conclusions Laparoscopic spleen-preserving distal pancreatectomy with splenic vessels preservation is the most suitable procedure for the distal pancreatic benign lesions,and in experienced hands this procedure is safe and effective.

OBJECTIVETo evaluate the feasibility and efficacy of laparoscopic distal pancreatectomy.

METHODSTotally 68 patients (male 23, female 45) aged 17 to 77 years, with distal pancreatic lesions, underwent laparoscopic distal pancreatectomy from November 2003 to December 2010. The clinical data were collected. Safety, feasibility and crucial technique manipulation were analyzed retrospectively.

RESULTSAll 68 operations were successful with two cases conversion to open, including 48 cases combined with splenectomy, and 18 cases with preservation of spleen. Fourteen cases received with combination resection of multi-organs, including 4 cases with cholecystectomy, 1 case resection of right adrenal adenoma and cholecystectomy, 1 case with myomectomy and left ovarian teratomectomy; 1 case with right ovarian teratomectomy, 1 case with resection of left adrenal adenoma, 1 case with resection of both adrenal adenoma, 1 case with resection of liver metastasis, 1 case with cholecystectomy and resection of liver metastasis, 1 case with resection of left adrenal adenoma and liver metastasis, 1 case with resection of left adrenal adenoma and colon and spleen, 1 case with biopsy of liver nodule. The mean operative time was (209 ± 58) minutes, the mean intraoperative blood loss was (191 ± 123) ml, and the mean postoperative hospital stay was (8 ± 4) days. The rate of overall postoperative complications was 18.1%, including an 12.1% rate of clinical pancreatic fistula. Only one case needed a reoperation, and there was no postoperative mortality.

CONCLUSIONLaparoscopic distal pancreatectomy with or without splenectomy is safe and feasible in the treatment of most distal pancreatic tumors.
