Objective To assess the methodological and ethical quality of randomized controlled trials (RCT) of non-small cell lung cancer ( NSCLC ) in China. Methods The methodological and ethical quality on RCT of NSCLC, covered in CBM, CNKI, VIP and Wanfang was assessed according to the Jadad Scale and Berdeu Scale respectively. Results The average methodological and ethical quality was 62. 24% according to the Jadad Scale and was 18. 79% according to the Berdeu Scale. Correlation analysis showed that the methodological quality was closely correlated with the ethical quality, except that of curative effect of invasive therapy (OR=1. 064, 95%CI:0. 832-1. 361, P>0. 05). Conclusion The methodological and ethical quality of RCT of NSCLC in China is low. The methodological quality is positively correlated with the ethical quality.

OBJECTIVE:To determine serum concentrations of western medicines in patients treated with "traditional Chinese antiepileptic medicine" alone and to evaluate the curative effects.METHODS:A total of 60 epileptic patients who visited our hospital between Feb.1997 and June 2006 were subjected to plasma drug level monitoring and during which the patients were treated with "traditional Chinese antiepileptic drugs" alone.Plasma concentrations of 4 kinds of western medicin-es were determined by FPIA.RESULTS:Of the 60 cases,valproic acid,carbamazepine,phenytoin and phenobarbitone were detected in 18,40,41,and 47 cases/times,respectively.On average,more than two kinds of western medicines were detected in every patient,and the blood concentrations were mostly beyond effective plasma drug concentration.The total curative effects were unsatisfactory.CONCLUSION:The fact that western medicine ingredients detected in these traditional Chinese antiepileptic medicines is inconformity with medication principle of epilepsy.Traditional Chinese antiepileptic medicines should be used with caution in the clinic in the treatment of epileptic patients.

Objective To investigate the effects of hypertonic saline/hetastarch solution (HHS) on stress hormones and glucose metabolism in hemorrhagic shock rabbit.Methods Fourteen rabbits of both sexes weighing 2.2-2.6 kg were randomly divided into 2 groups : HHS group ( n = 7) and lactated Ringer's solution (LRS) group ( n = 7). The animals were anesthetized with intravenous 20% urethane 5 ml? kg-1 . Femoral artery was cannulated for BP monitoring and femoral vein was cannulated for removal of blood and fluid infusion. Hemorrhagic shock was induced according to Wiggers. MAP was maintained at 45 mm Hg for 45 min. Then the animals in HHS group received HHS 6 ml? kg-1 and those in LRS group LRS 6 ml? kg-1 . Venous blood samples were taken before shock (baseline), during shock before resuscitation, and 30, 60, 120 min after fluid resuscitation for determination of plasma epinephrine, glucagon, insulin and blood glucose concentration. The insulin sensitivity index (ISI) was calculated.Results After resuscitation MAP returned to baseline level in HHS group while in LRS group MAP was still lower than the baseline. The plasma epinephrine, glucagon and blood glucose concentration increased significantly while plasma insulin concentration decreased significantly during shock before fluid resuscitation compared to the baseline in both groups. After fluid resuscitation plasma epinephrine and glucagon concentration decreased significantly and plasma insulin concentration increased significantly in HHS group whereas in LRS group plasma epinephrine, glucagon and insulin concentration kept increasing. The blood glucose level was significantly lower at 60 and 120 min after resuscitation in HHS group than in LRS group. ISI was decreased after resuscitation in both groups but was significantly lower at 60 and 120 min after resuscitation in LRS group than in HHS group.Conclusion Resuscitation with HHS can reduce the stress response and ameliorate the decrease in insulin sensitivity during hemorrhagic shock.

Objective To analyze the relationship between CT characteristics of chronic subdural hematoma (CSDH) and its recurrence, as well as relevant pathological mechanism. Methods The study involved 178 patients with CSDH who underwent surgery, of whom 38 patients (40 lesions) experienced recurrence of CSDH. Univariate and multivariate logistic analyses were performed to assess the correlation among CT characteristics ( including side, density, width, subtype and midline shift of the hematoma) and CSDH recurrence. Results ( 1 ) The width of hematoma, midline shift, type of hematoma were found to be correlated with the recurrence of CSDH in the univariate analysis. The odds ratio (OR)and 95% confidence interval (CI) value of patients with hematoma width ＞30 mm, midline shift ＞10 mm and the separated type were 18. 400 (2.024-167. 301 ), 4. 643 ( 1. 815-11. 877 ) and 14. 385 (3. 601-57.467 ), respectively. (2) The midline shift and type of hematoma were found to be correlated with the recurrence of CSDH in the multivariate analysis, when the OR and 95% CI value of patients with hematoma midline shift ＞ 10 mm and separated type were 5. 280 ( 1. 339-20. 823) and 19. 125 (4. 175-87.619), the OR and 95% CI value of patients with hematoma width ＞30 mm was 14. 838 ( 1. 353-162.698). Conclusions Type of hematoma and midline shift are found to be independently correlated with the recurrence of CSDH, and the width of hematoma is also related with its recurrence.

HPS1-D, an active polysaccharide,was isolated and purified from Hedysarum polybotrys. HPS1-D was obtained after treated with Savage method and H2O2, and purified with DEAE-cellulose 52 and Sephadex G-100 gel filtration chromatography. Then physicochemical property analysis, GC, methylation, partial acid hydrolysis, and NMR method were used to study chemical structural of HPS1-D. The conformation was primarily analyzed with GPC-MALLS method and Congo red reaction. The anti-complementary activity of HPS1-D was evaluated with the hemolysis assay. HPS1-D was a heteropolysaccharide and consisted of D-glucose, L-arabinose, (7.2:1.3). HPS1-D proved to be a neutral sugar, with 1, 4-and 1, 4, 6-alpha-D-glucopyranosyl residues in backbone ,and 1, 5-and 1, 3, 5-alpha-L-arabinofuranosyl residues in branches. HPS1-D has a random coil state conformation with monodisperse mass distribution in 0.9% NaCl solution. And HPS1-D had triple-helix conformation in concentrate of NaOH solution. Anti-complementary activity of HPS1-D was closed to its positive control heparin.

Objective:To summarize our experience in perioperative anesthetic management for fulminant hepatic failure (FHF)patients receiving liver transplantation.Methods:The clinical anesthetic data of 48 FHF patients receiving orthotopic liver transplantations(OLT)from January 2006 to January 2007 were retrospectively analyzed,and the anesthetic management expe- rience was summarized.General anesthesia was applied;the hemodynamics was monitored during the operation and doses of adrenaline and phenylephrine were adjusted according to the monitoring results.Blood samples were obtained before operation, before anheptic,30 min after anhepatic phase,5 min before neohepatic phase,and 5 min,30 min and 60 min after neohepatic phase for blood gas and electrolyte analysis and for determination of coagulation function;the drugs were subsequently adjusted according to analysis results.Results:All the 48 patient underwent successful anesthetic management and there was no death dur- ing opearation.The average blood loss during operation was(5 219?478)ml.Mild alkalosis,hypokalemia,hyponatrium,and hy- pocalcemia were present before operations,pH,BE and HCO_3~- were obviously reduced 30 min after anhepatic phase and in- creased 60 min after neohepatic phase.Kalemia was obviously increased 30 min following anhepatic phase and began to increase 60 min following neohepatic phase.Calium concentration was decreased at the end of preanhepatic phase(P

OBJECTIVETo understand the information of female patients with knee osteoarthritis regarding muscle force, constitution parameter.

METHODSThirty-seven cases diagnosed as knee osteoarthritis and 37 controls were examined by MES. T-test was used to analysis two groups differences of muscle force, constitution parameter, et al.

RESULTSCompared between affected limbs and controls limbs in patients revealed that the lower limb muscle distribution index of the affected limbs was higher than the control limbs (P<0.05), but comparison in functional status the lower limb muscle force, muscle functional index and muscle force of unit volume of the affected limbs were lower than the control limbs (P<0.05). Compared between patients group and control group the muscle force of both lower limbs, muscle functional index and muscle force of unit volume were lower than control group (P<0.001).

CONCLUSIONThe utility muscle force of lower limbs of female patients with knee osteoarthritis is weaker than healthy female. Muscle function disorder instead of muscle atrophy is the key cause of the weakness.
