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 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.

To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

ObjectiveTo investigate the protective effect of pyrroloquinoline quinone (PQQ) on damage of hippocampal neurons induced by NMDA.MethodsHippocampal neurons were cultured in vitro and NMDA was used to induce neurotoxicity 8 d after, while PQQ were used or not before. The metamorphosis of hippocampal neurons was observed under the microscope. Intracellular calcium levels was measured by confocal laser microscopy. ResultsThe intracellular Ca2+ level increased rapidly after exposure to 0.1 mmol/L NMDA and resulted in neuronal necrosis and apoptosis. Otherwise, pretreatment of the cultured neurons with PQQ reduced the increase of the intracellular Ca2+ level and the neuronal necrosis or apoptosis induced by NMDA.ConclusionPQQ can protect hippocampal neurons from damage induced by NMDA.

OBJECTIVETo observe the effect and mechanisim of zoledronate sodium on periprosthetic osteolysis in rat induced by polyethylene particles.
METHODSTotal 30 adult male SD rats, weighting from 250 to 300 g, were selected and randomly divided into three groups: blank control group, model control group and zoledronate sodium group respectively, 10 animals for each group. No treatment was performed in the blank control group. In model control group and zoledronate sodium group, the modle of periprosthetic osteolysis in rats were made by implanting polyethylene particles and titanium rods into their right femurs. After operation, rats in zoledronate sodium group were administered with zoledronate sodium (0.1 mg/kg each week) through subcutaneous injection for 8 weeks, then the blood was obtained and all experimental animals were sacrificed to get the right femur specimens. The femur BMD, IL-1β, IL-6, TNF-α, serum TRACP5b and CTX-I were detected.
RESULTSCompared with the model control group, the femur BMD was increased, while IL-1β, IL-6 and TNF-α were all decreased in zoledronate sodium group; the serum TRACP5b and CTX-I level were both reduced in zoledronate sodium group.
CONCLUSIONThe zoledronate sodium could effectively inhibit periprosthetic osteolysis in rats induced by polyethylene particles, which might be realized by inhibiting the activity of osteoclasts and the expression of IL-1β, IL-6 and TNF-α. It provides a new method to treat periprosthetic osteolysis of the artificial joint prosthesis.
