1.Neoadjuvant therapy for rectal cancer
Cancer Research and Clinic 2010;22(7):440-442
The neoadjuvant therapy for rectal cancer included neoadjuvant radiotherapy, neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and neoadjuvant molecular targeted therapy. Recent reports on neoadjuvant therapy clearly showed a downstaging and downgrading effect on the primary rectal cancer. The rates of R0 resection and sphincter preservation were improved and local recurrence was decreased, but the long term survival was not improved. The results of using new chemotherapeutics and molecular targeted drugs in neoadjuvant therapy for rectal cancer were expected.

Objective To investigate the effect of ampelopsin on apoptosis induction and cell growth inhibition in Human Colon cancer SW480 cells in vitro.Methods Treated with ampelopsin at several concentrations, MTT and flow cytometry was used to detect the inhibition rate and apoptotic rate of SW480 cells.Western-blot was used to investigate expression of Bcl-2 family pro-tein.Results Significant difference of cell growth inhibition rate was observed among all groups after treated with ampelopsin ( p<0.05).Cell growth inhibition rate in the low -dosage group was significantly high than that in median and high -dosage group (p<0.05), while no marked difference was observed between the median and high groups (p>0.05).The similar results were observed in the experiment on apoptosis induction.Level of Bcl-xL was significantly up-regulated.Level of Bax, Bid, Caspase-3, p-Ca-pase-9 and Caspase-9 was significantly down-regulated after treatment of ampelopsin.Conclusion Ampelopsin can inhibit cell growth and induce apoptosis of SW480.Bcl-2 family protein might be involved in the progress.

Taking hyperthyroidism, anti-hyperthyroidism drugs and anti-hyperthyroidism combination as the keywords, 121 litera-tures on hyperthyroidism treatment were reviewed on CNKI and VIP database, and among them, 37 ones were selected as the represent-ative references. The clinical application was reviewed and summarized. Thiourea drugs are the first choice in the clinical treatment of hyperthyroidism;however, they show obvious side effects. Therefore, the drug combination use, especially the combination of Chinese and western medicines was proposed, which could rapidly improve the symptoms and the quality of life, reduce the dosage of western medicines and adverse reactions, and consolidate the curative effect and prevent the recurrence.

OBJECTIVETo investigate the effect of the anticoagulants on PRP quality, so as to clarify the appropriate anticoagulant used in PRP production.
METHODSThe microstructure change of platelets collected via heparin, citrate, acid citrate dextrose (ACD) and citrate-theophylline-adenosine-dipyridamole ( CTAD) was observed by TEM following time course. The extent of spontaneous activation of platelets in four groups was detected by measuring sP-selectin in plasma. The TGF-β1 release amount of activated PRP of four groups was measured.
RESULTSCTAD is superior to other anticoagulants in maintaining the integrity of platelet structures for a long time and preventing platelet spontaneous activation. ACD slightly surpassed heparin and citrate in above two aspects. ACD-PRP and CTAD-PRP released significantly more TGF-β1 compared with heparin and citrate.
CONCLUSIONSThe PRP quality and biological effects were strongly associated with the type of Anticoagulants. ACD and CTAD are optimal anticoagulants in PRP production for they can maintain platelet viability at a high level.

Objective To assess efficacy and safety of enhanced rehabilitation program for patients with colorectal cancer surgery. Methods One hundred and ten consecutive patients admitted to general surgery department at Beijing Chaoyang Hospital during October 2007 to October 2009 undergone with fasttrack colorectal cancer surgery and enhanced rehabilitation were prospectively studied, with 117 patients undergone with same colorectal cancer surgery by traditional perioperative treatment during May 2005 to September 2007 as controls. Restoration of their gastrointestinal function, occurrence of complications, fatality and length of hospital stay after surgical operation were observed in the group of enhanced rehabilitation and control group. Results Demographic characteristics, stage classification of illness and surgical operation methods were comparable in both groups. The first day with air discharge from the flux was earlier in enhanced rehabilitation group than that in controls (2. 5 vs. 3. 5 day after surgery, P < 0. 05 ), and the former could tolerate solid food earlier than the latter (6.0 vs. 6.7 days after surgery, P=0.028). Overall morbidity of complications was less in the group with enhanced rehabilitation than that in controls (23.6% vs. 39. 3%,P =0. 011 ) and shorter length of hospital stay was observed in the former than that in the latter (9. 0 vs. 10. 8 days after surgery, P =0. 041 ). There was no difference in mortality, incidence of anastomotic leakage, and infectious and non-infectious complications between the two groups. Conclusions Enhanced rehabilitation program is safe and effective following colorectal cancer surgery to accelerate restoration of gastrointestinal function, reduce complications and shorten hospital stay after colorectal cancer surgery.

OBJECTIVE:To optimize the formulation and preparation technology of Propylthiouracil(PTU)solid lipid nanopar-ticles(PTU-SLN)and to evaluate the quality of PLN-SLN. METHODS:PTU-SLN was prepared by emulsion ultrasound dispersing method. The formulation of PTU-SLN was optimized by orthogonal design with the entrapment efficacy and particle size as index, using the amount of lipid material,soybean lecithin and poloxamer 188 and ultrasonic time as factors. The quality of prepared nanoparticles was evaluated with particle size,Zeta potential,entrapment efficiency,stability and in vitro drug release rate as in-dex. RESULTS:The optimal formulation and technology was as follows as lipid material 0.6 g,soybean lecithin 1.0 g,poloxamer 188 0.8 g,ultrasonic time 10 min. The obtained PTU-SLN was round and smooth in appearance and distributed evenly in particle size with average particle size of 93.5 nm,Zeta potential of -30.8 mV and average entrapment efficiency of 74.9%. Prepared nanoparticles had no significant change after placing for 15 d at 4 ℃. Accumulative release rate of PTU-SLN was 56.1% at 4 hour in vitro and reached 98.4% at 24 hour. CONCLUSIONS:PTU-SLN is prepared successfully and reasonable in technology,and can reach sustained-release effects.

To analyze the molecular mechanisms of cross-host transmission of the Aleutian mink disease vi rus (ADV), the hypervariable region fragment of the VP2 gene of the ADV in Jilin Province (China) was amplified. Sequencing analyses showed diversity at residue 174 by comparison with other VP2 genes in GenBank. The phylogenetic tree indicated that the ADV-JL strain had a close relationship with the highly pathogenic strain from Denmark: ADV-K. Results implied that residue 174 may be associated with ADV infectivity.
