Objective To discuss the effect of Billroth Ⅱ gastrectomy on glucose metabolism in patients with gastric cancer complicated with type 2 diabetes mellitus(T2 DM).Methods A retrospective study on the serum level of glucose in 7 patients with gastric cancer complicated with T2 DM undergone Billroth Ⅱ gastrectomy.The therapeutic regime for T2DM after the operation was also analyzed.Results Billroth Ⅱ gastrectomy was completed in all of the 7 patients by open surgery(3) or laparoscopy(4).No serious intra- and post-operative complications occurred in the series.The preoperative level of fasting plasma glucose(FPG) was between 6.6 and 9.0 mmol/L(mean 8.1 mmol/L) and glycosylated hemoglobin concentrations(HbA1c) between 6.8% and 9.5%(mean 7.8%).While 1 to 8 months after the surgery,the FPG decreased to 4.8-7.9 mmol/L(mean 6.4 mmol/L) and HbA1c 5.5% to 7.2%(mean 6.3%).According to the criteria from ADA,4 patients were cured and 3 were improved.Conclusion Billroth Ⅱ gastrectomy is effective for type 2 diabetes mellitus in patients with gastric cancer.

The article presented the drugs supply management mode reform in place since 2009 in the one district of Shanghai.Authors analyzed and commented the implementation and outcomes,and studied the potentials of successful promotion nationwide.They hold that such a mode works to some extent in terms of reducing management costs of medical institutions,lowering drug purchase price,encouraging rational drug use of such institutions,and reforming the compensation manner for medical institutions.This mode,however,calls for an operating environment in need of not only funding support,but also new concepts and economic development strength of the society as a whole.This means that such a mode is only recommended in developed areas in China.

MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs of-22 nucleotides that exist in a wide variety of organisms,including animals,plants and virus.Mature miRNAs are able to control gene expression at a post-transcriptional level,either by blocking mRNA translation or inducing their degradation.Hepatitis B virus X protein (HBX) is a 17000 protein that is implicated to play a crucial role in hepatocarcinogenesis.Recently,many studies have shown that HBX is associated with miRNA regulation,and is involved in regulating fundamental biological processes of tumor in cell proliferation,differentiation and apoptosis.

Objective To study the analgesic effects of combination of fortanodyn and verapamil. Methods Used the model of the acetic acid induction writhing in mice and the method of hot-plate in mice, then observe the action of the mice after treatment with combination of fortanodyn and verapamil. Results Low dose Verapamil com-bined AP237 (40 mg/kg, 80 mg/kg)could enhance the threshold of pain of the mouse ache response obviously, and postponed the time which the mouse ache appeared (comparing using simply AP237 P <0.05 with controlled group P <0. 01) ;Low dose Verapamil combined AP237 (20 mg/kg,40 mg/kg) had the obvious inhibitory action in the body turning times of the mouse. Conclusion Verapamil can strengthen the analgesia function of AP237.

AIMTo investigate the effects of c-myb on progesterone-induced mouse germinal vesicle(GV) stage denuded oocyte (DO) maturation in vitro.
METHODSWe used mouse GV stage oocyte cultured with special concentration progesterone, or/and antisense c-myb ODN, or/and db-cAMP, or/and heparin for 24 h, and observed oocyte maturation and analysed the relationship among them.
RESULTSWe cultured DO in the medium 199 for 24 h, and found 10 micromol/L progesterone had more significant effect than 5 micromol/L progesterone (2 h GVBD% P < 0.05, 8 h PB 1% P < 0.05), but had not more significant effect than 20 micromol/L progesterone. We found that 16 micromol/L antisense c-myb ODN significantly inhibited progesterone (10 micromol/L)-induced mouse germinal vesicle stage oocyte maturation in vitro (2 h GVBD% P < 0.05, 8 h PBI% P < 0.01). 1 x 10(-4) micromol/L dbcAMP, 100 microg/ml heparin could single significantly inhibited progesterone-induced mouse GV stage oocyte maturation in vitro (2 h PBI% all P < 0.01, 8 h PBI% all P < 0.01), and could enhanced the inhibition of 16 micromol/L antisense c-myb ODN (2 h GVBD% all P < 0.01, 8h PBI% all P < 0.01).
CONCLUSIONProgesterone, protooncogene c-myb,cAMP and calcium all pay important role in regulating oocyte maturation and the mechanism of progesterone, cAMP and calcium in regulating oocyte maturation may be through the expression of protooncogene c-myb.
