Objective To evaluate the efficacy of calcium(Ca)and magnesium(Mg)infusions in pre- vention of oxaliplatin-induced acute neurotoxicity.Methods Fourty-two patients with advanced colorectal carcinoma were eligible for the study:21 were assigned to the Ca/Mg ann and 21 to the control arm.The Ca/ Mg arm and the control arm were comparable for patients'characteristics.Chemotherapy regimen were al- most the same in both arms.Chemotherapy regimen consisted of oxaliplatin 130 mg/m~2 on day 1,given as a 3-hour infusion in 500 ml of 5% glucose,concurrent with rahitrexed 3 mg/m~2 as a 15-minute intravenous (Ⅳ)infusion or calcium folinate(CF)200 mg?m~(-2)?d~(-1),days 1～5,5-Fluorouracil(5-Fu)500 mg?m~(-2)?d~(-1),days 1～5.Therapy was repeated every 3 weeks.The treatment consisted of Ca gluconate and Mg sulfate,1 g each, delivered i.v.over 15 min just before the oxaliplatin infusion and repeated at the same dose after the comple- tion of the oxaliplatin infusion.A specific neurotoxicity scale was used for oxaliplatin-related neurotoxicity. Results Ten patients(47.62%)had acute neurotoxicity in the Ca/Mg arm compared with 19 patients (90.48%)in the control arm(P0.05).Conclusion Ca/Mg infusions seem to reduce incidence and intensity of oxaliplatin-induced acute neurotoxicity,and they do not reduce the clinical activity of oxaliplatin,but dosage and administration schedule could be optimized.

The basic physiological function of anti-arrhythmic drugs is affects myocardial cell membrane ion channels. Change the ion flow and affect cell electrophysiological properties, change the conduction velocity, eliminate retrace, inhibit autorhythmicity and trigger events, inhibit the occurrence of arrhythmia, but will trigger a new activities, new retrace, produce new arrhythmia. In recent years, with the improvement of the theoretical system of traditional Chinese medicine and the production of new research methods, Chinese medicine treatment of arrhythmia has a new development. This article summarized the recent decades of which Chinese medicine monomer anti-arrhythmic drugs that had been proved by the influence of monomer anti-arrhythmic drugs, lists the differents traditional Chinese medicinal materials which chemical composition and the effective of the anti-arrhythmic effects, shows the unique advantages of Chinese medicine in the aspect of anti-arrhythmic, and points out that the current Chinese medicine in anti-arrhythmic (monomer) existing problems and solutions.

OBJECTIVE: To investigate the serum IgE with various postmortem intervals (PMI) in guinea pigs due to sudden death from anaphylactic shock and to explore the effect of refrigeration of corpse on serum IgE level and its application value in forensic medicine. METHODS: The animal death models of anaphylactic shock were established. The corpses were preserved at room temperature (20 °C ) for 6 h and then refrigerated at 4 °C. The serum was sampled at 6, 12, 24, 36 and 48 hours after death. The IgE level of serum was detected with ELISA. The control group was also established. RESULTS: The serum IgE level had significant. difference between the experimental group and the control group (P < 0.05). There was no significant difference among the experimental groups at 6, 12, 24, 36 and 48 hours post- mortem (P > 0.05). CONCLUSION If the corpses were placed in 4 °C conditions 6 hours after anaphylactic death, the serum IgE still shows a good marker within 48 h for forensic investigation.

Objective To investigate the distribution of water fluoride and the present status of water-improving defuoridation projects in the endmie fluorosis areas in Gansu Province in 2006. Methods The content of fluoride in drinking water in 18 endemic disease counties was screened, and the defluoridation projects built after the 1980s were supervised and inspected. The content of fluoride in drinking water was assessed by F-ion selective electrode. Results Fluoride content was determined in water of 6260 sources in 1252 fluorosis villages in 18 counties, with 63.50% (3975/6260)≤1.0 mg/L and 36.50%(2285/6260)>1.0 mg/L. Nine hundred and ninty-seven water-improving and clefluoridation projects had been investigated in 16 counties, among which 95.49% (952/997) were function well, and projects intermittently running or abandoned respectively accounted for 3.11% (31/997) and 1.40%(14/997). Nine hundred and eighty-three sources of water treated by the water-improving and defluoridation projects had been determined for fluoride content, it turned out that 91.76% (902/983) were within the standard, only 8.24% (81/983) were not; as for outlet and leftover water of 934 water-improving and defluoridatian projects determined for water fluoride content, qualified projects accounted for 92.08% (860/934) and 91.97%(859/934), leaving 7.92%(74/934) and 8.03%(75/934) disqualified, respectively. Water-improving and defluoridation projects mostly relied on drilling a well in gaining under-ground water or collecting surface-ground water, so under-ground water and surface-ground water are the majority. Conclusions Water fluoride content exceeds the standard in some of the villages. A few projects do not function well. Fluorosis damage still exists in Gansu Province, therefore countermeasures for endemic fluorosis must be carried out as promptly as possible and surveillance on water-improving and defluoridation projects must be strengthened and managed.

Objective To study prognosis of patients with fulminant hepatitis after plasma ex- change treatment using model for end-stage liver disease(MELD)scoring system.Methods 160 pa- tients were randomly divided into plasma exchange group and control group,and MELD score was calculated according to the original formula for each patient.The efficacy of plasma exchange was as- sessed by mortality and improvement in biochemical parameters and MELD score.Results The levels of total bilirubin(TBIL),INR and MELD score of patients whose MELD scores were between 30 and 40[TBIL,(379.4?40.4)?mol/L; INR,2.5?0.2; MELD,30.8?3.8]were lower than before PE treatment[TBIL,(509.7?64.6)?mol/L;INR,3.5?0.3;MELD,37.3?3.5].The levels of TBIL and INR and MELD score of patients whose MELD scores were higher than 40 [TBIL,(595.6?61.5)?mol/L;INR,3.8?0.4;MELD,39.8?3.5]were lower than before PE treatmem [TBIL, (650.4?66.3)?mol/L;INR,4.4?0.6;MELD,45.2?4.2].The mortality of patients in PE group with MELD score from 30 and 40 was 50.0%,while it was 86.7% in control group,showing significant differ- ence between PE group and control group(P＜0.01).The mortality of patients with MELD scores higher than 40 was 91.2% in PE group and 100% in control group,showing no significant difference between these two groups(P＞0.05).Conclusions Plasma exchange treatment can decrease the serum TBIL level, INR and MELD score of patients with fulminant hepatitis and improve liver function.Compared with the control group,plasma exchange can significantly decrease the mortality of patients in PE group with MELD score from 30 to 40,but no effect on patients with MELD score higher than 40.

Objective To evaluate the clinical efficacy of lamivudine in preventing liver injury induced by anti-tuberculosis drugs in hepatitis B virus(HBV)carriers.Methods One hundred and ten HBV carriers treated with anti-tuberculosis drugs were randomly divided into lamivudine group and control group.Patients in both groups were treated with conventional anti-tuberculosis drugs (isoniazid,rifampicin,pyrazinamide,streptomycin or ethambutol)for 6-8 months.However, patients in lamivudine group were treated with lamivudine 100 mg orally dairy concomitantly.Before and after treatment,the clinical manifestation,liver function and serum HBV DNA level of patients were evaluated.Statistical analysis was performed using t test and x~2 test.Results During 6-8 months of treatment,the incidence rate of liver injury was 9.1% in lamivudine group,while it was 38.2% in control group(P0.05).Conclusion Lamivudine is effective and safe in reducing liver injury induced by anti-tuberculosis drugs in HBV carriers.

Objective To investigate the prevalence of tumor necrosis factor-?(TNF-?)promoter polymorphisms(at position-308 or-238)in patients with nonalcoholic fatty liver disease(NAFLD),and to explore the relationship between TNF-? promoter polymorphisms and obesity and the insulin resis tance(IR)in those patients.Methods Metabolic variables were measured in 117 patients with NAFLD, among them 60 were obesity and 57 were non-obesity.Genotype of TNF-? promoter were determined by PCR-RFLP.Plasma TNF-? level was measured by ELISA.Indexes of IR and insulin secretion were determined using the homeostasis model assessment method.One hundred and twenty normal subjects who were matched for age and sex served as control.Results The G→A mutation of the-238 TNF-? polymorphism was significantly higher in patients with NAFLD versus controls(29.9% vs.15.8%, P
