To investigate the deletion of MTS1/p16 gene in human colorectal carcinoma,the homozygous deletion of MTS1/p16 gene was checked by reverse transcriptase polymerase chain reaction from 60 patients with colorectal carcinoma.The specimens consisted of 35 colorectal carcinoma,15 tumor-adjacent tissues and 10 normal colorectal mucosa. It was found that 17 14% (6/35) colorectal carcinoma specimens showed homozygous deletion of MTS1/p16 gene.No deletion was detected in tumor-adjacent tissue and normal colorectal mucosa.Deletion of MTS/p16 gene may play a role in the progression of colorectal carcinoma.

Objective To investitgate the level of polychlorinated biphenyls in retail livestock meat.Methods Totally 28 samples of three kinds of meat including of beef,pork and mutton were collected during Aug-Dec.,2008.Twelve dioxin-like polychlorinated biphenyls(DL-PCBs) and six marker PCBs were extracted by Soxhlet extractor,cleaned up by FMS and qualitative and quantitative analyzedsis by isotope dilution high-resolution gas chromatography/high resolution mass spectrometry(HRGC/ HRMS).Results Levels of total 18 compounds including of 12 DL-PCBs and indicator PCBs in beef,pork and mutton were 1 607.60 pg/g fat,435.82 pg/ g fat,and 505.17 pg/g fat respectively,DL-PCBs concentration were 456.19 pg/g fat,46.37 pg/g fat and 77.50 pg/g fat respectively.Maker-PCBs concentration were 1 151.41 pg/g fat,389.45pg/g fat and 427.67 pg/g fat respectively.The levels of PCB toxicity equivalent(TEQ)(the median value)were:0.84 pg/g fat in beef,0.15 pg/g fat in pork,0.28 pg/g fat in mutton respectively.The TEQ concentration of PCB(median value) was lower than the EU action level limit value.In all samples,PCB118 was the greatest contributor to the total contaminated concentration,and PCB126 was the dominant contributor to toxicity equivalent(TEQ).Six of 28 samples exceeded the limit value of the EU action level.Conclusion The results show that PCBs contamination exists in a city from the six samples exceeding the EU standard limit.It should take measures to explore the cause of contamination of PCBs compounds and control the pollution in order to guarantee food safety effectively.

Objective To investigate the main causes and strategies for the difficulties in ureteroscopic lithotripsy.Methods From March 2004 to December 2006,19 cases of ureteral calculi,who experienced difficulties during holmium laser lithotripsy or pneumatic lithotripsy under a rigid ureteroscope,were analyzed retrospectively.Among the cases,3 had difficulties in ureteroscope placement due to the narrow ureteral ingress,6 owing to calculus obstruction complicated with ureteral inflammatory polypi,4 resulted from twisted ureter,and 6 because of stenosis of the ureter.Results In 15 of the patients,the operation was successfully performed by changing surgical approach,controlling the hydraulic irrigation,and incising the stenotic segments,etc.Two patients,who had stenotic ureter,received ESWL with double-J catheter dwelling.Lithotripsy failed in 2 cases,and PCNL was used to remove the calculi.The postoperative complications occurred in 4 cases,including 2 with mucosal laceration and 2 ureteral perforations.One of the 4 cases was transferred to an open surgery,and the other 3 were cured by conservative treatments.Conclusions Holmium Laser lithotripsy and pneumatic lithotripsy under a rigid ureteroscope are safe and effective in treating ureteral calculi.

Objective To access the clinical value of interstitial brachytherpay in patients with advanced carcinoma. Methods 6 patients(1 case of hepatic cancer,3 cases of prostate cancer,2 cases of local recurrence of rectal cancer)received interstitial high dose rate(Ir-192)brachytherpay with afterloading technique(6.0 Gy/day in 4 days) Tubes were inserted with laparoscopic guidance to minimize the risk of tube misplacement. Results The size of the tumors was reduced and the local control rate was encouraging(6/6). one patient with local recurrence of rectal cancer aquired CR,the ofher five cases acquired PR.

[Objective] To investigate the curative effect of the red rice in treating the experimental fractures in the rats.[Methods] 64 Wistar rats suffered with single fracture in the forearm were randomized into two groups,one red rice group and the other normal saline control group.On the twenty-first day and 42 day after operation,the qualitation and morphometric observation of the bone tissue were performed.[Results] After the treatment of the red rice,the bony union of the fractured bone in the rats was obviously accelerated.The morphometric index of the bony tissue was higher than the control group with the statistical significance.The remodeling of the bony callus,the emergence of the lamellar bone and recanalization of the medullary cavity could all be enhanced by the use of the red rice.The mineralized bony callus area,the osteoblast index and the matrical calcification were obviously higher than those of the control group.[Conclusions] The growth of bony callus,the index of the osteoblast,the metrical calcification and the remodeling of the bony callus could all be enhanced by the red rice and therefore the bone union could be accelerated.
