50 000 bp)was extracted from frozen gastric cancer tissue and their corresponding normal samples and used for RLGS assay.The genome DNA was digested by methylation-sensitive restriction enzyme Not Ⅰ, and labeled by radioisotope ~(32)p,then separated by two-dimensional electrophoresis and autoradiography. Experimental conditions for each step were optimized step by step.DNA fragment sequences for the dots on scanning profile were identified according to the human RLGS database.Results RLGS assay was set up and used to get the RLGS profiles of the representative tested samples successfully.These profiles can display more than 1 200 available dots averagely,the profiles of high quality DNA sample can display more than 1 800 dots which is the average level at an excellent RLGS lab,discrepant dots which had weaken or enhanced signals and their sequence information were obtained.The result can be reproduced.Conclusion The RLGS assay is established,stabilized for detection of DNA methylation of tissue samples.

The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

Objective To study the factors influencing the curative effect of one-stage bihteral total hip arthroplasty in a sequential procedure.Methods Thirty-six patients were indicated for one-stage bilateral total hip arthroplasty from February 1998 to March 2008.All cases were made with Smith-Peterson incision.Results The operative time was(3.2±1.2)h.The volume of blood transfusion during operation was (620 4±120)ml.All the 36 patients were followed up for(22.0±6.0)months.Except for 1 case of deep venous thrombosis of lower limbs,1 case of limb length discrepancy,there were no severe complications,such as postoperative infection,pulmonary embelism,dislocation,loosening or subsiding of components.Postoperative Harris scoreg of the joint function[(88.0±3.6)points]was significantly improved compared with their preoperative Harris scores[(28.0±4.2)points](P<0.05).Conclusions One-stage bilateral total hip arthroplasty is an effective method.However.the satisfactory effects can only be achieved by strict case selection,sufficient preoperative preparation,attention to operation procedures,prevention of complications and active recovery after operations.

Objective To detect the expression of tenascin-C(TN-C)and tenascin-X(TN-X)in the embryonic heart of rats,investigate their role during the heart development.Methods Sixty-four Spraque-Dawley female rats and 20 male rats were put into the same cage,when vaginal suppository was found,the femate was pregnant 0.5 day(ED 0.5),then executed the pregnant rats on ED 12.5,ED 15.5 and ED 19.5,got out the hearts.Semi-quantitative reverse transcriptase-polymerase chain reaction(RT-PCR)was used to detect the TN-C and TN-X mRNA expression in the rat hearts aged embryonic day 12.5(ED 12.5),ED 15.5 and ED 19.5.The protein expression of TN-C and TN-X in the embryonic hearts was detected by immunohistochemistry.Results TN-C mRNA was highly expressed in ED 12.5 embryonic hearts(0.683 7?0.043 1),the expression of TN-C mRNA of ED 15.5(0.454 3?0.038 8)and ED 19.5(0.250 5?0.038 4)embryonic hearts decreased,they were different from the expression of ED 12.5(Pa

OBJECTIVE:
To study the expressions of focal adhesion kinase (FAK) and phospho-FAK( p-FAK) during skin incised wound healing and the applicability of time-dependent expressions of FAK and p-FAK.
METHODS:
The expression of FAK and p-FAK in cutaneous incised wound in mouse were investigated by immunohistochmeistry and Western blotting.
RESULTS:
FAK and p-FAK expression were detected in polymorphonuclear cells (PMNs) in the wound and adjacent regions 3 hours post-injury. The expressions of FAK and p-FAK were detected in a large number of infiltrating PMNs and some of mononuclear cells (MNCs) from 6 to 24 hours after injury. The MNCs and fibroblastic cells (FBCs) accounted for most part of the FAK and p-FAK positive cells from 3 to 14 days after injury. The numbers of FAK-positive cells increased continuously, reaching a peak at post-injury day 3, and then started to decrease from post-injury day 5 to 14. The changes of p-FAK-positive cells were similar to that of the FAKs, and reached a peak at 12 hours after injury.
CONCLUSION
Both FAK and p-FAK displayed a time-dependent expression during skin incised wound healing in mouse, with p-FAK being superior to FAK. Both FAK and p-FAK may potentially be used as new markers for determination of the wound interval.

OBJECTIVETo study the necessity, feasibility, security of carotid angioplasty and stenting (CAS) for symptomatic carotid stenosis combined with kinking.
METHODSTwelve patients with symptomatic carotid stenosis and kinking demonstrated by digital subtraction angiography (DSA) received CAS from December 2003 to December 2009. There were 9 male and 3 female patients, age ranged from 59 to 77 years (mean 69.3 years). All the patients' clinical, imaging, intervention and follow up data were collected and analyzed.
RESULTSAll CAS procedures were successfully performed with 14 self-expandable stents placed. The mean degree of stenosis was reduced from 85.6% before stenting to 11.2% after stenting, the angle of kinking, according to Metz' category, were improved from less than 90° to more than 120° in each case. No perioperative procedure related stroke and transient ischemic attack (TIA) occurred. The clinical symptoms and signs of cerebral ischemia were improved or disappeared for all patients. During follow-up of these 12 patients for 6 to 72 months, one patient experienced ipsilateral carotid territory TIA and another patient experienced contralateral carotid territory TIA. DSA follow up of 5 patients demonstrated 1 case with in-stent restenosis and arterial kinking remote to the stent of internal carotid artery. CAS were performed again and CT angiography follow up demonstrated no kinking and restenosis 2 years after the intervention. Duplex scan of the other 7 patients demonstrated neither kinking nor restenosis.
CONCLUSIONSCAS seems to be feasible and safe for the patients with symptomatic kinking and stenosis, and maybe helpful to lower the risk of cerebral ischemia, but further study is needed.
