Objective To observe the effect of different doses of propofol injection and propofol medium/long-chain fat emulsion injection in short time infusion on plasma ketone body ratio,to eva-lute its effecton hepatic energy metabolism.Methods Forty patients,aged 18-50 years old,ASA Ⅰ orⅡ undergoing selective surgery were randomly divided into 4 groups with 10 cases in each;propofol injection 4 mg·kg-1·h-1 maintain anesthesia (group L4 ),propofol injection 6 mg·kg-1·h-1 maintain anesthesia (group L6 ),propofol medium/long-chain fat emulsion injection 4 mg·kg-1·h-1 maintain anesthesia (group M4 ),propofol medium/long-chain fat emulsion injection 6 mg·kg-1·h-1 maintain anesthesia (group M6 ).MAP,HR,SpO2 and PET CO2 were recorded before anesthesia induction (T0 ),after tracheal intubation (T1 ),after 2 hours infusion of propofol (T2 )and operation completed (T3 ).The blood samples were collected at T1 and T2 to detect the level of acetoacetate,β-hydroxybu-tyrate and to calculate the blood ketone body ratio (the ratio of acetoacetate andβ-hydroxybutyrate). Results MAP,HR,SpO2 ,PET CO2 at T0-T3 and acetoacetate,β-hydroxybutyrate,blood ketone body ratio at T1 ,T2 showed no significant statistic difference.Conclusion Different doses of propofol and different doses of propofol medium/long-chain fat emulsion injection in short time continuous in-fusion has no obvious effect on hepatic energy metabolism;same dose of propofol injection and propo-fol medium/long-chain fat emulsion injection in short time continuous infusion has no obvious effect on hepatic energy metabolism.

Objective To evaluate the efficiency and safety of Percusurge guardwire distal protection system in coronary intervention in patients with acute myocardial infarction. Methods Three male patients with acute myocardial infarction were enrolled in the study. Primary angioplasty was performed for 2 of them, 2 and 7 hours after onset of the infarction symptom, respectively. Selective angioplasty was performed 17 days after infarction for the third case. Percusurge guardwire system was used during the procedure. Results Procedure success was achieved for all of the 3 cases. Lot of thrombus was sucked out. The infarct-related arteries had TIMI 3 flow at the end of the procedures. The patients′ symptoms were resolved soon after the procedure. Minor dissection was seen in one case which did not obstruct the distal flow and was left alone. Conclusion Percusurge guardwire system can be used safely and effectively in coronary intervention in the thrombus-laden arteries such as acute myocardial infarction.

Objective To study the characteristics of infarct-related-artery (IRA) in acute high lateral wall myocardial infarction and to give clinical clue for deducing the location of coronary artery lesions. Methods Ninety-six patients with acute high lateral wall myocardial infarction (77 males, 19 females, mean age 57.3?10.7 years) were enrolled in the study. They all had infarction for the first time and were confirmed to have single vessel coronary artery disease by coronary angiography. The patients were divided into 3 groups according to the ECG changes at the onset of infarction. The first group (group A) was simple high lateral wall infartion (23 cases). The second one (group B) was high lateral with anterior wall infarction (58 cases, among them 27 cases with anteral-septal infarction and the other 31 with extensive anterior infarction). The third group (group C) was high lateral with lateral wall infarction (15 cases). Lesion characteristics of IRA were analyzed. Results The infarction-related lesions were mainly on left anterior descending arteries in group B (56/58), and on left circumflex in group C (13/15). But those in group A could be on either diagonal (12/23) or left circumflex (11/23). The difference of distribution of IRA among these groups was statistically significant (P

Objective To investigate the correlation between atherosclerotic renal artery stenosis and hypertension.Methods One hundred and seventy-nine patients underwent renal artery angiography after coronary artery angiography. Results Among the 179 patients, 56.4% patients were detected as renal artery normal, 24% as renal artery disease, and 19.6% as renal artery stenosis. Compared with hypertensive patients with normal renal artery, ARAS patients had higher systolic blood pressure (148?23 mm?Hg vs 136?18 mm?Hg, P

Objective: Medical therapy to prevent persistent ectopic pregnancy (PEP) after conservative laparoscopic operation was investigated. Methods:236 patients with ectopic pregnancy were divided into three groups according to the time of hospitalization. 83 cases were in group A, hyperosmolar glucose was injected into the fallopian tube lumen after laparoscopic salpingostomy. 81 cases were in group B, MTX was injected in the same way, 72 cases were in group C as control group. Serum β-HCG was tested for four times, before the operation, the first, third and a week after the operation respectively. Results:There were 6 patients of PEP in this study. One patient in group A, one patient in group B, the rest four patients in group C. The incidence of PEP was not statistically significant between group A and B( P>0. 05), while the difference was significant between group A and C ( P<0. 05). Serum β-HCG in three groups descended significantly in the first 24 hours after operation, but there were no differences among these groups. As for the descending of β-HCG in day 3 and 7, there was no difference between group A and B, but the difference was magnificent between group A and C( P < 0.05). Conclusions: Compared with the MTX, hyperosmolar glucose is an effective and safer method to prevent PEP.

Objective To learn the control status of iodine deficiency disorders in Baoji City of Shaanxi Province.Methods From 2009 to 2011,according to the National Iodized Salt Monitoring Program,the iodized salt was monitored,and thyroid was examined in 12 counties(areas) of Baoji City.According to rural and urban area stratification,60 children aged 8 to 10 were selected in each county(district),and their urine samples were collected for determination of iodine content.In 2011,per capita daily salt intake was surveyed by the three weighing method at children's home whose urine was collected.Chencang Area,Fufeng County and Taibai County,representatives of Baoji City different geomorphic features were selected for investigation of water iodine,and urinary iodine of pregnant and lactating women,and 15 people were selected in each county (district).Results From 2009-2011,in the 12 counties(areas) in Baoji City,the coverage rate of iodized salt was all 100.00％(3468/3468); the qualified rate of iodized salt and the consumption rate of qualified iodized salt were all ＞ 99.00％.Children's goiter rate was 3.41％(87/2548),3.06％(77/2520) and 3.33％(84/2520),and they were all less than that of the national standard (＜ 5％).Medians of urinary iodine of 8-10 years old children were 368.20,293.80 and 332.50 μg/L,respectively,and the ratios of urine iodine ≥300 μg/L were accounted for 66.42％ (797/1200),48.05％(692/1440) and 56.67％(816/1440),respectively.Median urinary iodine of pregnant women was 301.81 μg/L and lactating women was 329.79 μg/L.A total of 1116 households were investigated,the median of per capita daily salt intake was 8.9 g.Eighteen water samples were collected,range of water iodine value were 0.60-10.25 μg/L.Conclusions Iodine nutrition in general population of Baoji City is exceeded the optimum level,and the current iodized salt concentration has some down space,but fully consideration should be taken on iodine needs in different iodine deficiency areas and among different groups of people.

Objective: To investigate the effect and mechanism of Astragalus Injection (Radix Astragali) on acute murine myocarditis caused by Coxsackievirus B 3. Methods: Acute viral myocarditis was induced in 24 Balb/c mice by injection of Coxsackievirus B 3m (CVB 3m ) intraperitoneally. Half of the mice were administered Astragalus Injection(10g/kg?d). Heart and blood samples were obtained from all mice on the 8th day after CVB 3m infection for histopathological study, detection of myocardial perforin expression by reverse transcription polymerase chain reacton(RT PCR) and measurement of serum CK MB level, respectively. Results: (1) Astragalus treated mice showed a significant reduction in myocardial lesion compared with that in untreated mice. (2) Myocardial perforin expression by semi quantitative RT PCR in Astragalus treated mice was much lower than that in controls(1.10?0.07 vs 1.31?0.12, P

Objective To learn the existing state of Keshan disease and its trend in Baoji City,and to provide a scientific basis for control of the disease.Methods Feng,Qianyang,Linyou and Long Counties,the Keshan disease affected areas were selected to carry out the case study,and Keshan cases were searched from all registered cases of myocardial patients of the past three years at county-level medical institutions and hospitals of townships(towns).Thirteen villages affected by Keshan disease in Qianyang,Fengxiang,Feng,Linyou and Long Counties were selected as monitoring points to carry out a intensified monitoring.All subjects were surveyed by comprehensive clinical physical examination and 12-lead ECG tracings,and they were diagnosed according to the Keshan disease diagnostic criteria.Ten households were selected randomly in each monitoring point(village),and self-produced wheat samples and adult subject's occipital hair samples were collected for detecting selenium levels.Results Seven hundred and forty-six cardiac cases which containing 17 cases of chronic Keshan disease were discovered in 32 medical institutions,and there were no acute and subacute type of Keshan disease patients.Five thousand seven hundred and twenty-three subjects were examined in the 13 monitoring sites,and 65 cases of Keshan disease were diagnosed which including 17 cases of slow and 48 cases of potential Keshan disease,and no acute or subacute case was found.The total detection rate was 1.14％,and the detection rate ranged from 0 to 2.86％.Hair selenium mean was 0.420 mg/kg; wheat selenium mean was 0.079 mg/kg.Conclusions The Keshan disease detection rate of Baoji City is at a low level.The selenium level of local residents has reached the level of non-endemic area.Constant detection of patient with Keshan disease means various control measures should be reinforced.The comprehensive monitoring program,such as monitoring people's in vivo and in vitro selenium level and others,should be established as soon as possible.
