L-Carnitine plays an essential role in the transfer of long chain fatty acids from the cytoplasm of a cell into the mitochondrion,where they undergo ?-oxidation.Carnitine deficiency is characterized by plasma and tissue carnitine concentrations below those required for the normal functions of the organism,including cardiomyopathy,myopathy,hypoketonemia,hypoglycemia,hyperammonemia.Studies show that supplement of carnitine could improve the clinical symptoms of some diseases.

It has been reported that the level of antioxidants is lower in obese patients compared with that in normal weight subjects. Important antioxidants, vitamin E and ?-carotene, are lowered in obese adults and children, which may cause lipid super oxidation and are associated with atherosclerosis, coronary heart disease and myocardial infarction. Copper and zinc are trace elements that compose parts of enzymes such as CuZn-superoxide dismutase (CuZn-SOD) which can scavenge free radicals. Plasma copper and zinc levels are lowered in obese individuals, which may lead to abnormality in glucose metabolism.

ObjectiveTo compare the effects of two methods for the treatment of delayed defecation of neonatal meconium. Methods Sixty-seven neonates with delayed defecation of neonatal meconium were divided into experiment group (n=37) and control group (n=30). The former group was managed with abdominal massage followed by glycerol enema and the latter with abdominal massage followed by anus stimulation.Then the groups were compared in terms of the time for initial defecation of meconium,the volume of defecation,exhanstion time for defecation,abdominal distention and vomiting and serum bilirubin within 7 days.Result The treatment group was superior to the control one in terms of time for initial defecation of meconium,the volume of defecation, exhanstion time for defecation (P<0.05) and the incidences of abdominal distention,vomiting and serum bilirubin within 7 days were significantly lower than the control group (P<0.05).Conclusions The method of glycerol enema combined with abdominal massage is more effective for promoting defecation of neonatal meconium than the method of anus stimulation.It can reduce the incidence of abdominal distension,vomiting and pathological jaundice.

0.05),and losantan was not harmful to the livers and kidneys.Con- clusion There were not only good effect of losantan on curing hyperuricemia,but also it had no bad reactions.

Objective To assess the clinical outcomes of glutamine supplementation in neonates.Methods The study was designed as a double-blind randomized controlled trial.Totally 100 infants were randomly divided into 5 groups with 20 infants in each group:control group:standard parenteral nutrition (PN);PNI group:PN supplemented with 0.3 g/ (kg·d) glutamine;enteral nutrition (EN) 1 group:EN supplemented with 0.3 g/ (kg·d) glutamine;PN2 group:PN supplemented with 0.3 g/ (kg·d) glutamine;and EN2 group:EN supplemented with 0.3 g/ (kg·d) glutamine,The primary endpoints were the time to establish full enteral nutrition [defined as receiving 120 ml/ (kg·d) enterally],episodes of gastric residuals,total duration of PN,and mortality.The second endpoints were weight gain and head circumference gain,liver function,renal function,days on ventilator,and length of hospitalization.Results Time to achieve full enteral nutrition,incidence of gastric residuals,duration of PN,weight gain (g/d) ,head circumference gain (cm/w),liver function,renal function,and length of hospitalization were not significantly different among all five groups.Days of mechanical ventilation were significantly decreased in PN1 group and PN2 group when compared with the control group (P ＜ 0.05).Intention-totreat analyses showed that,when compared with the control group,PN1 group:RR:1.053;95% CI:0.952-1.164;ENI group:RR:1.333,95% CI:1.035-1.717;PN2 group:RR:1.053,95% CI:0.952-1.164;EN2 group:RR:1.25,95% CI:1.004-1.556.Conclusions Glutamine supplementation may not be able to decrease the time to achieve full enteral nutrition,the incidence of gastric residuals,and the duration of PN.However,pareneral glutamine supplementation does reduce the days on ventilator in neonates.Also,parenteral glutamine supplementation has no obvious influence on mortality.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

Objective To investigate the distribution and characteristics of advanced schistosomi-asis in Hunan Province in order to provide some references for policy making of the control program. Methods The survey scheme of advanced schistosomiasis was made out, in which investigation variables and diagnostic criteria were standardized. The survey was carried out in the whole province. Results There were 5 405 cases of advanced schistosomiasis, reduced by 21. 64% compared with the registration number in the previous files. The prevalence rate was 8. 69/10 000, of which 16. 21% was new cases, 97. 06% were distributed in lake regions and 2. 94% in hilly regions. Of total cases, 78. 70% was located in transmission areas, 15.64% in transmission controlled areas, and 5. 66% in transmission interrupted areas. Cases with splenomegaly made up 59. 4%, ones with ascitis 37. 30% and colonic granulomatous and dwarfism type 3. 16%. Male cases took up 77.39% and female ones 22.61%. In the splenomegaly type 52.24% of patients had performed splenectomy. The youngest case was 14 years old and the oldest 90 years old. Cases of 50-, 60- age group made up 65. 18%, and 32.7% of cases came from 30-, 40-, 70- age group and 2. 09% from the remaining age groups. Farmer took up 87. 58% of all occupations and others occupied 12. 42%. Conclusion The advanced schistosomiasis cases in Hunan Province are showing the falling tendency, although some new cases occur. The main advanced cases come from the farmer in lake regions.

Objective: To develop a method for determination of carnitine in serum using HPLC. Methods: The serum proteins were precipitated by acetonitrile and methanol. The organic extract was added derivatizing reagent and the solution was warmed to 60℃ for 2 hours. Atlantis C18 column (4.6 mm?150 mm,5?m)was used as stationary phase and methanol-ispropand-acetonitrile (35∶45∶20,v/v) as mobile phase; flow rate 1.0ml/min, UV wavelengh at 260nm. Results: The typical chromatogram from serum samples showed clear separation of carnitine. Y= 8490X-48200, r= 0.9999. Intra-day RSD was 1.6%-13.2%, and inter-day 1.8%-12.1%. The recovery rate was 98.5%. Conclusion: A method for determination of carnitine in serum using HPLC by adding derivatizing reagent was developed and it is simple, rapid and precise, and can be used for clinical test.

Objective To study the effect of interventional treatment of iliac and femoral vein stenosis concomitant with deep venous thrombosis. Method Fifty-three patients were divided into 5 groups. In group A after placing into inferior vena cava a filter,11 patients adopted Amplatz Trombectomy Device for thrombolysis or ORSIS thrombolysis and persistent thrombolysis through popliteal vein. In group B thrombus was taken out through guiding catheter and then persistent thrombolysis through popliteal vein after placing into inferior vena cava filters in 9 cases. In group C 13 patients adopted persistent thrombolysis through femoral arteries. In group D 8 patients received persistent thrombolysis through popliteal vein. In group E persistent thrombolysis through foot veins was carried out in 12 patients. Seventeen patients received implanted stents and balloon-expansion in iliac and femoral veins. Results Symptoms disappeared in 26 patients(49.0%), significantly improved in 21 patients (39.6%), improved in 3 patients (5.7%), did not improve in 3 patients (5.7%), respectively. The repatency of iliac and femoral vein was achieved in more than 80% of the 17 patients. Complications developed in 3 cases in the course of thrombolysis. Conclusion The effect of mechanical removal of thrombus, persistent thrombolysis through catheter and transluminal angioplasty is safe and satisfactory.
