The research frontiers in foreign medical informatics were analyzed according to the co-occurrence net-work map, hotspots density map and cluster tree map that were plotted for the PubMed-covered scientific papers on medical informatics from 2010 to 2014 , which showed that the research frontiers in foreign medical informatics were the natural language processing and data mining of electronic health records, medical decision-making assistant system, computer-aided drug therapy, clinical decision-making support, health service attitude, health service quality, health service model, medical records system and its linkage, information system and its integration.

Expression of apelin mRNA in the isolated mouse adipocytes was confirmed by Northern blot. The level of apelin mRNA increased during stage of differentiation of 3T3-L1 cells. Insulin up-regulated the apelin expression in 3T3-L1 adipocytes, suggesting that apelin expression in adipocyte may correlate with obesity, insulin resistance and hypertension.

Objective To explore the value of blood lipid and CA125 in identification diagnosis between lung cancer and pulmo‐nary tuberculosis .Methods The blood lipid and serum CA125 levels in 131 patients with lung cancer( Ⅰ - Ⅳ stage) ,53 patients with pulmonary tuberculosis and 60 normal controls were determined by biochemstry ,immunoturbidimetry and electrochemilumi‐nescence immunoassay and was done compared study .Results The serum TC and HDL‐C level in 131 patients with lung cancer were decreased with severity and were lower than in those of in 53 patients with pulmonary tuberculosis(TC :P< 0 .05 ,< 0 .05 ,<0 .01 and < 0 .001 respectively ;HDL‐C :P< 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively) .The serum LDL‐C level was no differ‐ences between lung cancer( Ⅰ - Ⅲ stage) and in 53 patients with pulmonary tuberculosis(P> 0 .05) only the lung cancer( Ⅳ stage) was a little increased(P< 0 .05) .The serum TG and ApoB/ApoA1 ratio levels in 131 patients with lung cancer( Ⅰ - Ⅳ stage) were increased with severity and were significantly higher than in those of 53 patients with pulmonary tuberculosis (TG :P < 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively ;ApoB/ApoA1 :P< 0 .05 ,< 0 .05 ,< 0 .01 and < 0 .01 respectively) .The level of CA125 in 131 patients with lung cancer was significantly higher than in those 53 patients with pulmonary tuberculosis(P< 0 .001) .Conclusion The serum TC and HDL‐C ,TG ,ApoB/ApoA1 ratio and CA125 levels may be the indexs of identification diagnosis between lung cancer and pulmonary tuberculosis .

Objective To discuss the value of 256 spiral CT dynamic volume scanning in the diagnosis of moyamoya disease.Methods Twenty-three patients with moyamoya disease undergoing 256 spiral CT dynamic volume scanning (moyamoya group) were selected,and 18 patients having cerebrovascular disease symptoms,but the brain artery without stenosis (control group) were also selected.The volume reconstruction (VR),maximum intensity projection (MIP) and cerebral CT perfusion imaging was displayed.The cerebral CT perfusion imaging parameters of anterior,middle,posterior cerebral artery were measured and analyzed.Results VR,MIP could well reproduce lesion location,degree of stenosis and skull base abnormal vascular network change.Compared with control group,the cerebral blood volume (CBV) was increased [(8.46 ±0.91) ml/100 g vs.(2.92 ±0.72) ml/100 g],time to peak (TTP) was increased [(30.27 ±5.02) s vs.(24.83 ±4.07) s] in anterior cerebral artery,and there was significant difference (P ＜ 0.01),but there was no significant difference in the cerebral blood flow (CBF),the mean transit time (MTT)(P ＞ 0.05).Compared with control group,CBV was increased [(8.06 ± 1.05) ml/100 g vs.(6.08 ± 0.56) ml/100 g],MTT,TTP was increased [(6.34 ± 1.01) s vs.(3.83 ± 0.83) s,(32.06 ± 2.55) s vs.(25.83 ± 2.34) s] in middle cerebral artery,and there was significant difference (P＜ 0.01),but there was no significant difference in CBF (P ＞ 0.05).Compared with control group,there was no significant difference in the cerebral CT perfusion imaging parameters of posterior cerebral artery (P ＞0.05).Conclusion 256 spiral CT dynamic volume scanning can be combined with morphology and function imagings,and has important guiding significance for diagnosis of moyamoya disease.

Hypertriglyceridemia, and the ectopic deposition of triglycerides, are the risk factors for insulin resistance. To clarify the mechanism of regulations in triglyceride metabolism is an approach to the elucidation of pathogenesis and effective treatment of insulin resistance-related diseases.

ObjectiveTo investigate the feasibility and effectiveness of low central venous pressure (LCVP) in the operation of major hepatic resection.MethodsFourty-eight patients underwent major hepatic resection were randomized into two groups: LCVP and control group.In the LCVP group,CVP was maintained ≤5 cm H2O during the hepatic resection and then returned to normal after resection.In the control group,CVP was maintained normal between 6 -12 cm H20.The duration of hepatectomy,volume of blood loss,volume of blood transfused and renal function were compared between the two groups.ResultsFor the LCVP and control group,the time for hepatectomy was (45 ± 8 ) and ( 35 ± 5 ) min,respectively; the volumes of blood loss were ( 850 ± 160) and (436 ±280)ml,respectively; the blood loss during operation was (490 ± 130) and (270 ± 105 ) ml respectively.The differences were statistically significant (t values were 15.53,7.69 and 17.89 separately,P ＜0.05 ).No significant difference in the renal function was observed before and after the operation ( P ＞ 0.05 ).Conclusion Using LCVP technique during liver resection significantly reduced the operation time,blood loss and blood infusion.And there wa.s no obvious adverse effect on renal function.

Resistance is one of the most important reasons that restrict the clinical application of most chemotherapeutic medicines. Docetaxel is a very widely applicated antitumor medicine. Most of the researches on the mechanism of resistance against docetaxel focused on the drug transporters, changes in drug metabolism and pathway alteration of cell cycle and apoptnsis. The mechanism of docetaxel resistance and the predictive data based on clinical research to docetaxel therapy in cancer treatment were reviewed.
