1.The role of serum dihydropyrimidine dehydrogenase activity in patients with gastric cancer resistance to fluorouracil: a prospective study
Chinese Journal of Postgraduates of Medicine 2008;31(12):6-8
Objective To investigate the mechanism of the fluorouracil(FU)drug resistance and to prove deeply the role of serum dihydropyrimidine dehydrogenase(DPD)activity in patients with gastric cancer resistance to FU with the level of cell culture. Methods The peripheral blood was collected from 45 patients with advanced gastric cancer before chemotherapy to detect the activity of DPD by high performance liquid chromatography(HPLC).The patients were divided into two groups(high activity group and low activity group)according to the results. The FU drug inhibitory rate of gastric cancer cell cultured in vitro were tested with MTT to compare the effects of the two groups. Result The FU drug inhibitory rate of gastric cancer cell cultured in vitro was obviously lower in high activity group than that in low activity group,(47.6±±4.0)%,(53.7±8.0)%respectively. Conclusion The activity of serum DPD may be simple and convenient indicators in predicting the resistance to FU.
2.Asymmetric dimethylarginine and diabetes with cerebrovascular diseases
International Journal of Cerebrovascular Diseases 2010;18(6):450-455
Nitric oxide (NO) is the most important known endogenous vasodilator factor. The competitive inhibitor asymmetric dimethylarginine (ADMA) of endothelial nitric oxide synthase (NOS) inhibits NO synthesis, which makes NO/NOS pathway to be obstructed and the reduction of NO synthesis. The studies in recent years have suggested that ADMA is as-sociated with the occurrence and development of diabetes with cerebrovascular disease. It has provided new insights into further clarifying the mechanism of the disease.

Journal of Chinese Physician 2016;18(4):497-500,504
Objective To investigate the analgesic efficacy of ultrasound guided transversus abdominis plane block and to compare the efficacy of posterior approach and medial approach of ultrasound guided transversus abdominis plane block (TAPB) in providing postoperative analgesia after children laparoscopic groin surgery.Methods Eligible children 2 ~ 4 years old (n =60),American society of anesthesiologists (ASA) I,undergoing elective laparoscopic unilateral groin surgery were randomly assigned into posterior approach group (Group P),medial approach group (Group M) and control group (Group C).Many parameters were measured and recorded during the study,including funk sedation scores,intraoperative circulation monitoring at time points of T1 (before induction),T2 (skin incision) and T3 (skin closure),length of surgery,the time from post anesthesia care unit (PACU) arrival to the first obtainable pain score,length of PACU stay,modified-children's hospital of eastern ontario pain scale(m-CHEOPS),pediatric anesthesia emergence delirium (PAED) scores,number of children with sufentanil administered in PACU,number of people occurred nausea and vomiting,and satisfaction of parents.Results There were no statistically significant difference in general characteristics,basic emotion score,duration of surgery,the time from PACU arrival to first obtainable score,haemodynamic parameter at T1 and satisfaction of parents among groups P,M,and C.However,the m-CHEOPS scores at the time points of first obtainable,10 min,the number of children received sufentanil administration,PAED scores and haemodynamic parameter at T2 and T3 were significantly lower in groups P and M than in group C.There were no significant difference in parameters mentioned above between groups P and M.Conclusions Ultrasound guided transversus abdominis plane block could provide efficient and secure postoperative analgesia for children undergoing laparoscopic groin surgery.Both posterior approach and medial approach are ideal options.

Objective: To study the antioxidative and hepatoprotective activities of low molecular fucoidan oligosaccharides(LMFO) from Laminaria japonica in mice.Methods: Mice were pretreated with LMFO(50?100?150 mg/kg ig respectively, 10 days),and then 0.2 % CCl 4 10 ml/kg ig and D-GalN(600 mg/kg)+LPS(lipopolysaccharide,1 ?g/kg) ig respectively in two model groups to induce liver injury. Liver injury was assessed by quantifying activities of plasma GPT, SOD, GSH-Px and MDA content.Results: The increase of plasma GPT activity was significantly inhibited by LMFO in two liver injury models, suggesting that LMFO had good protective effect on the hepatocytes. LMFO had good antioxidative effect in mice with liver injury induced by CCl 4 and D-GalN+LPS as indicated by decreased MDA content and increased activities of plasma SOD and GSH-Px. Conclusion: LMFO is protective against CCl 4-induced and D-GalN+ LPS induced liver injury in mice and its effect may be due to its antioxidative activities in vivo.

Objective To investigate the application value of low dose high pitch dual source CT angiography technique in diagno-sis of acute aortic dissection.Methods 21 cases of critically ill patients with suspected aortic dissection underwent total aortic angiog-raphy without using ECG by adopting the second generation dual source CT Flash Technology (pitch 3 .2 ,1 0 0 kV and 1 0 0 mAs), using a lower contrast dose (60 mL).Results All subjects accepted as low as possible radiation doses and iodine intake;at the same time,accurate information including aortic intimal tear position,intimal flap,true and false lumen,and lesions involving the range vessel signs and anatomic relationship were received,2 cases of Stanford type A,type B 1 9 cases (2 cases of aortic rupture).Average scan time 2.6 s,average effective radiation dose cm 270 mGy·cm.Conclusion High quality images by using high pitch dual source CT low dose angiography with lower contrast dose provide safe,reliable,real-time screening method for critically ill patients with aor-tic dissection caused by systemic severe compound injury.

Objective To investigate the inpatients' evaluation of quality nursing care and disucss different data collecting methods on patients's evaluation of quality nursing care. Methods Patients measure up to standard (82 cases) were divided into the questionnaire group and the interview group with 41 patients in each group. The questionnaire investigation was carried out in the questionnaire group by applying 4 themes of quality nursing care. The interview group used structured interview instead. The results of the two methods were compared and analyzed. Results The score of quality nursing care of the questionnaire group was higher than that of the interview group (P<0.01) in evaluating health education method. In humanistic environment patients in the questionnaire group thought nurses could protect their privacy, respect their personality and treat them and their family members kindly. Besides visiting institution was reasonable. All of these were the demonstration of quality nursing care. The above results were different from those of the interview group (P<0.01). Conclusions Patients had comprehensive requirement on quality nursing care. Nurses should, use this as reference, regulate their service behavior and improve nursing quality.
