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.

China Journal of Chinese Materia Medica 2014;39(8):1544-1546
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.

Methods T he anim al death m odels of anaphylactic shock w ere established. T he corpses w ere preserved at room tem perature (20℃) for 6 h and then refrigerated at 4℃. T he serum w as sam pled at 6, 12, 24, 36 and 48 hours after death. T he IgE level of serum w as detected w ith ELISA . The control group w as also established. Results The serum IgE level had significant difference betw een the experim ental group and the control group (P<0.05). T here w as no significant difference am ong the experim ental groups at 6, 12, 24, 36 and 48 hours post-m ortem (P>0.05). Conclusion If the corpses w ere placed in 4℃ conditions 6 hours after anaphylactic death, the serum IgE still show s a good m arker w ithin 48 h for forensic investigation.

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.

Purpose The aim is to evaluate the effects of rhIL-11 made in China on hematopoietic recovery following chemotherapy-induced thrombocytopenia in cynomolgus monkeys.Methods Chemotherapy-induced myelosuppression of cynomolgus monkeys was made by china iv cyclophosphamide ( 30 mg/kg, qd ) for 5 days, then animals were divided 6 groups(n=4), by sc rhIL-11( 50, 100, 200 μg/kg), or Neumega (GI rhIL-11 control, 100 μg/kg) for 14 days, another normal control and model control. Blood was taken before chemothery and then at day 3, 6,9,12,15,18,21 for blood cell counts and platelet congregate test. Bone marrow was aspirated day 0, 12 and 21 for evaluation of the megakaryocyte ploidy distribution.Results Recovery of blood platelets was accelerated and reached normal levels by day 12, and was higher than normal day 18, day 21 sc rhIL-11 in cynomolgus moneys. Blood platelet congregated rate were 71.4%~74.6% by day 21 and higher than model control . megakaryocytes in bone marrow increased.Conclusion rhIL-11 could accelerate the recovery of peripheral blood platelets in monkeys. The function of increased platelets was normal. The results supported the clinical use of rhIL-11 as a platelet restorative agent to prevent severe thrombocytopenia following chemotherapy.
