Objective To investigate clinical significance of proinsulin and true insulin in obese children with impaired glucose tolerance (IGT).Methods There were 21 IGT and 52 normal glucose tolerance (NGT) children. Control cases were 40 normal children. The levels of serum fasting proinsulin,true insulin,insulin,c-peptide and glucose were measured in all the subjects.Results 1.Levels of fasting proinsulin,c-peptide, glucose, insulin, true insulin and homeostasis insulin resistance in obese children with IGT showed significant difference compared with NGT (P

OBJECTIVE:To compare the cost-effective ratios between Granisetron and Ondansetron in the prevention of Cisplatin-induced nausea and vomiting.METHODS:In a randomized auto-controlled design,36patients receiving chemotherapy with Cisplatin were divided into2groups to compare the antiemetic effects and toxicity between Granisetron and Ondansetron and to carry out cost-effectiveness analysis.RESULTS:Granisetron could effectively prevent Cisplatin-induced nausea and vomiting and its antiemetic effect was comparable to that of Ondansetron.The average effective rates in preventing nausea and vomiting of Granisetron and Ondansetron were75.9%,77.8%and79.7%,75.0%respectively,and there were no significant differences between two drugs.The toxic reactions of Granisetron were slight.In cost-effectiveness analysis,Granisetron was better than Ondansetron.CONCLUSION:Granisetron is a safe,effective,economical antiemotic in chemotherapy of cancers.It is worth popularizing the application.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To investigate DNA methylation status as well as signal transducer and activator of transcription 3 (STAT3) gene expression in peripheral blood T-lymphocytes from patients with systemic lupus erythematosus (SLE),and to explore their relationship.Methods Peripheral blood samples were obtained from 34 patients with SLE and 23 healthy controls followed by the isolation of T-lymphocytes.Flow cytometry was performed to evaluate DNA methylation status using antibodies against 5-methylcytosine (5-me),reverse transcription (RT)-PCR to detect the mRNA expression of STAT3 in T-lymphocytes.Results Compared with healthy controls,17 patients with active SLE showed significantly decreased DNA methylation levels (8.50 ± 1.42 vs.11.31 ± 1.34,P ＜ 0.01),but increased STAT3 mRNA expression levels (1.34 ± 0.32 vs.1.02 ± 0.28,P ＜ 0.01).However,there were no significant differences between 17 patients with stable SLE and healthy controls in DNA methylation levels (11.30 ± 1.34 vs.11.31 ±1.34,P ＞ 0.05) or STAT3 mRNA expression levels (1.01 ± 0.27 vs.1.02 ± 0.28,P ＞ 0.05).Patients with active SLE also showed significantly reduced DNA methylation levels,but enhanced STAT3 mRNA expression compared with those with stable SLE (both P ＜ 0.01).As Pearson correlation analysis showed,SLE disease activity index (SLE-DAI) was negatively correlated with DNA methylation levels in patients with SLE (r =-0.78,P ＜ 0.01),but positively correlated with STAT3 mRNA expression (r =0.50,P ＜ 0.01),and no significant correlation was observed between STAT3 mRNA expression and DNA methylation levels (r =-0.13,P ＞ 0.05).Conclusion The aberrant expression of STAT3 in peripheral blood T-lymphocytes may be related to disease activity in SLE,but unrelated to DNA methylation levels.

Objective To evaluate the diagnostic values of diffusion tensor imaging(DTI)in early radiation-induced brain injury of the temporal lobes.Methods Conventional and MR diffusion tensor imaging examinations were performed in 23 patients following radiotherapy for nasopharyngeal carcinoma(NPC)and in 28 age-matched healthy controls.Isotropic apparent diffusion coefficient(ADCiso)and anisotropic index were measured in the white matter on both of the temporal lobes.Results The value of ADCiso,fractional anisotropy(FA),relative anisotropy(RA)and 1 minus volume ratio(1-VR)were(644.08?56.80)?10-6 mm2/s,0.394?0.074,0.344?0.075 and 0.182?0.072 respectively.In comparison with control group,these values were significant decreased(P

Objective To provide a clinical anatomic basis for the bi-pedicled gastrocnemius myocuta- neous flap which is to be used to repair defects of the Achilles tendon and posterior skin of the ankle.Methods In anatomic study,out of 30 cadaver specimens,bi-pedicled V-Y gastrocnemius myoeutaneous flaps were harvested to measure the downward sliding lengths of the flap when the knee was at flexion of different degrees.In clinic,12 patients with the Achilles tendon and posterior ankle skin defects were repaired with the bi-pedicled gastrocnemius myocutaneous flaps.The areas of composite defects ranged from 10 cm?6 cm to 6 cm?4 cm.They were followed up for four months to 12 years.Results The maximal sliding length of the flap reached (9.2?0.9)cm when the knee was at flexion of 90?.All the clinical flaps survived and ambulation of the patients recovered.The dorsiflexion and plantarflexion of the ankles reached 11.0??1.4?and 35.0??4.6?respectively.Conclusion This flap is suitable for one-stage repair of composite Achilles tendon defects.

Objective: To ascertain the process condition of extraction Mashi Granules(Herba Ephedrae, Gypsum Fibrosum, Radix Puerariae, Herba Methal, Semen Armeniacae Amerum, etc.) Methods: In combination with area under the curve of hypothermy in rabbits, process water, macerating time and boiling times were used as parameters in uniformidy design. And then appropriate excipients were selected on the basis of hygroscopicity and granulation. Results: 20 times amount of water as much as herbs was added, macerating time reached as far as 40 min, and extracted 3 times, 2h a time. Excipient formula consisted of lactose and mannitol(4∶1, w/w). Conclusion: The experimental results provide the basis for the ascertainment of extracting process and formulation of Mashi Granules.
