Journal of Applied Clinical Pediatrics 1994;0(04):-
Objective To observe the effect of nerve growth factor(NGF) on Caspase-3 expression in hippocampus of epileptic rats induced by kainic acid(KA) and explore the protective effect and mechanisms of NGF on the epileptic neurocytes.Methods Sixty healthy rats aged 21 to 30 days were randomly divided into 3 groups,each of which included 20 rats.Rats in group A were treated with 9 g?L-1 sodium,rats in group B were treated with KA,rats in group C were treated with KA and NGF.Concentration of KA was 2 g?L-1 diluted by 9 g?L-1 sodium;KA was injected into rats in group B and group C,intraperitoneally.Then state of seizure was recorded,and EEG and pathological section were performed.Five rats in each group were sacrificed by perfusion with paraform respectively at 6 hour,on the 1st day,on the 3rd day after injection of KA.Specimen was sampled and made into frozen section.Expression of Caspase-3 in hippocampus of epileptic rats was analyzed by immunohistochemistry.And microscope image measuring and analysis instrument was used to analyze image of expression.Results Symptoms of seizure appeared 30 min after injection of KA.Seizure was proved by detection of EEG and pathological section.Expressions of Caspase-3 detected by immunohistochemistry in group C decreased at every time spot were higher than those in group B,and the defferences between 2 groups had statistically significant(Pa

Objective To observe the functions of far-infrared rays and negative ions in Tourmaline and explore its new healthcare usage. Methods Questionnaires were adopted to obtain changes of diabetic patients in terms of dyskinesia,dysreflexia, abnormal skin and muscle, kinesthesis, touch sensation, algesia, and temperature sensation after using Tourmaline bedding series. Results Diabetic patients in fight and moderate level get improvements after using the series for one year,although the patient in fight level get outstanding improvements. Data showed the shorter therapeutic courses the better therapeutic effects were obtained and the improvements highlighted the changes of pain, ferver, hypesthesia, numbness, hight attack symptoms, and motion abnormality. Motion abnormality, algesia, and temperature sensation are three sensitive indexes of this disease. Conclusion Tourmaline bedding series has the function of improving peripheral neuropathy, which may be related with Tourmaline producing far-infrared rays and negative ions.

Objective To investigate the effect of somatostatin on pancreatic blood flow and pancreatic function on the patients with acute pancreatitis.Methods 120 patients with acute pancreatitis from March 2015 to March 2017 were collected, and were randomly divided into the observation group and the control group.The control group were given routine treatment, at the basis of this, the observation group were given somatostatin.octreotide 0.6 mg was dripped into intravenous continuously, and was reducted to 0.3 mg, continuous treatment for 7 d.The changes of blood flow and the curative effect of pancreas were compared between the two groups before and after treatment.Results The total effective rate was 96.67%(58/60)in the treatment group and 80.00%(48/60)in the control group.The total effective rate in the observation group was significantly higher than that in the control group, the difference was statistically significant (P<0.05).There was no significant difference in blood flow(BF), blood volume(BV)and capillary surface permeability(PS)between the two groups before treatment.1 and 7 days after treatment, BF, BV in the observation group were higher than those in the control group, the levels of PS were significantly lower than that in the control group, the differences were statistically significant(P<0.05).Before treatment, the differences of(CP), insulin(INS), glucagon(GLU), serum lipase(LIP), amylase(AMY)and trypsinogen-2(TPS)were measured in the two groups were not statistically significant.1 and 7 days after treatment, CP and INS in the observation group were significantly higher than those in the control group, and GLU, LIP, AMY and TPS-2 were significantly lower than those in the control group, the differences between the two groups was statistically significant (P<0.05).Conclusion It has a protective effect on pancreatic blood flow and function which somatostatin was used in the treatment of the patients with acute pancreatitis, it can improve the overall state of pancreas, and has significant therapeutic effect.

Clinical re-evaluation is to verify the drug's safety and effectiveness again,while the drug itself has not been improved. However, due to the complexity of traditional Chinese medicine, ingredients in bulk drugs, prescription, productive processes, quality standards and other aspects need to be enhanced. So improving the quality, safety and effectiveness of traditional Chinese medicine by clinical re-evaluation is also very necessary. Therefore, except for achieving those basic requirements of medicine, it should also be improved on itself and pay full attention to the particularity, then traditional Chinese medicine's clinical re-evaluation will play its due role.

Objective To investigate the changes of body composition in the children with acute leukemia during different treatment stages.Methods From January 2009 to April 2010,56 children with acute leukemia hospitalized in Shanghai Children's Medical Center for chemotherapy were enrolled.Meanwhile,56 healthy children with matched age and sex were enrolled as the control group.The body compositions of children in the control group and the children with acute leukemia at the end of the first course of each treatment stages ware detected by segmental multiple-frequency bioelectrical impedance analysis.The distribution of body compositions was recorded asthe percentage of each body composition to the body weighL Results Among 56 children with acute leukemia,41were with acute lymphoblastic leukemia and 15 with acute nonlymphoblasdc leukemia.Twenty-three cases were in remission-induction chemotherapy stage,15 in consolidation chemotherapy stage,and 18 in maintenance chemotherapy stage.Compared with children in the control group,children with acute leukemia showed a reduction in the percentage of intracellular fluid (P = 0.000), extracellular fluid (P - 0.005), protein (P = 0.000), mineral (P = 0.001), skeletal muscle mass (P = 0.000), body cell mass (P = 0.000), and active cell mass (P = 0.000), while an increase in body fat mass [(26.2 ± 8.3)% vs.(20.3±3.8)%, P=0.000].The body weight (P = 0.001), the percentage of intracellular fluid (P = 0.005), protein (P = 0.004), body cell mass (P = 0.001), and active cell mass ( P = 0.020 ) in the children during remission-induction chemotherapy stage were significantly lower than those of the healthy children.However, the parameters of the consolidation chemotherapy stage were significantly lower than those of the control group, including the percentage of intracellular fluid (P = 0.000), extracellular fluid (P =0.000), protein (P = 0.000), mineral (P =0.001), body fat mass (P =0.000), non-fat mass (P = 0.000), skeletal muscle mass (P = 0.000), body cell mass (P = 0.000), and active cell mass (P = 0.000).Most body compositions in the maintenance chemotherapy stage were lower than those of the healthy children ( P < 0.05) except for body mass index (P = 0.127) and the percentage of extracellular fluid (P = 0.097).Conclusions Body compositions remarkably change in children with acute leukemia after chemotherapy.Therefore, the nutritional status of children with acute leukemia should be closely monitored, and proper nutritional support should be provided when necessary to improve the prognosis.
