Objective To explore diagnosisand treatment of intestinal obstruction by foodballs in children. Methods The clinical datum of 21 cases of intestinal obstruction by foodballs in children were retrospectively ana- lyzed.Results While admission,only 2 cases could provide the history of having eaten foodballs wholly which could not be digested easily.The characteristics of clinical manifestation were intestinal obstruction completely or incom- pletely.All 21 cases had been treated conservatively first,only one case was successful and the other 20 cases had been cured by surgery afterwords.Conclusion There is no specific feature in clinical manifestations of intestinal ob- struction by foodballs in children,so it is difficult to make the diagnosis,but it must be considered suspicious especial- ly for those from rural area and with simple intestinal obstruction with reasons not known yet.If conservative therapy is failure in a short period,an operation should be done immediately.During operation,it is necessary to examine the whole digestive system thoroughly.

Objective To investigate the impact of anesthetization and manipulation on neurotransmitters glutamate and dopamine during cell transplantation. Methods Neural stem cells cultured in vitro from postnatal rats were implanted into the striatum of normal adult rats. Brain microdialysis combined with high-performance liquid chromatography (HPLC) was applied to dynamically detect the impact of microdialysis probe implantation, anesthetics ketamine and pentobarbital and implanted cells etc on glutamate and dopamine levels. Results After 15 min probe implantation into the rat striatum, glutamate and dopamine levels in the striatum increased, evidently higher than the baseline value and declined to the baseline level within about 5-6 h. Ketamine and pentobarbital anesthetization for 15 rain resulted in a transient increase in glutamate and dopamine levels in the rat striamm;there were no significant effects on in vivo glutamate and dopamine levels by cell implantation itself. Conclusion Routine doses of intraperitoneal ketamine or pentobarbital anesthetization may result in a transient increase in glutamate and dopamine levels within the brain extracellular space. Based on these data, the optimal time for commencing brain microdialysis on glutamate and dopamine should be at least 6 h after probe implantation.

Objective To study the survival,migration and differentiation of the neural stem cells which transplanted into ventral horn of spinal cord after brachial plexus avulsion.Methods Neural stem ceils isolated from spinal cord of neogenetic rats and cultured,expanded,labeled by BrdU before transplanted. Twenty adult healthy SD rats preformed as the model of brochial plexus avulsion(Roots C_(5～7)),then transplan- rod stem ceils into the C_6 ventral horn of spinal cord.On 1,2,4,8,12 weeks postoperatively,immunohisto- chemistry assay were carried out in the spinal cord.Results Transplanted into ventral horn of spinal cord after brachial plexus avulsion.Neural stem cells can survive,migrate for at least one segment of spinal cord and differentiate to neurons and astrocytes.The differentiation of stem cells were time-depends.Conclusion Neural stem cells can survive,migrate and differentiate after transplanted into ventral horn of spinal cord in the rats which suffered from brachial plexus avulsion.

Objective To retrospectively investigate and compare the clinical features in type 2 diabetic patients with various lesions of diabetic nephropathy.Methods One hundred and fifty patients of type 2 diabetes mellitus were registered from December 1990 to April 2004,among them 73 cases of diffuse glomerulosclerosis (DIF)and 77 nodular glomerulosclerosis(NOD)were all proven by renal biopsy.Data such as the durations of diabetes mellitus and hypertension,body mass index(BMI),diabetic retinopathy,HbA_1c,plasma albumin, proteinuria,urine N-acetyl-?,-glucosaminidase,urine osmolarity,ereatinine clearance rate(Ccr)were collected and compared.Results(1)Compared with the patients with DIF,the patients with NOD had longer duration of diabetes mellitus[(122.0?8.1 vs 56.0?7.8)months,P

Isolation of high-quality genomic DNA from dried and processed crude drug is the key for the DNA identification of Dendrobii Caulis. The DNA extract of Dendrobii Caulis was firstly compared using different method to isolate genomic DNA from dried and processed crude drug, including commercial DNA extracted kit and CTAB method. Using modified CTAB method (extracted from large samples), the genomic DNA was successfully isolated from Dendrobii Caulis, including Huangcao and Fengdou. The ITS regions were amplified using the purified DNA as template, and then cloned and sequenced. These ITS sequences were compared with data from Genbank database and our lab, 14 Dendrobium species and five similar species were identified from "Huangcao" and "Huangcao" slice, while six species and three similar species from "Fengdou" according to their sequence similarity. The study demonstrated that the dried Dendrobii Caulis could be identified using DNA molecular method, which could overcome deficiencies and limitations of traditional identification method and has a certain application prospects.
