OBJECTIVE:To observe the curative and preventive effects of reco mbinant basic fibroblast growth factor(rbFGF)on radio mucitis.METHODS:120patients with head and neck carcinoma were randomly divided into the therapy group and control group with60patients in each group,1week after radiotherapy till the end,the therapy group were given1ml of rbFGF by oral spraying5puff,3times daily after meal and the patients in the control group mouthwash with compound borax solution3times daily after meal.RESULTS:Radio mucitis in therapy group was less serious than that in the control group(P

0.05).Meanwhile,they both had significant differences compared with group C(P

Objective To investigate the role of Akt signal pathway on the expression of monocyte chemoattractant protein-1 ( MCP-1 ) and nuclear transcription factor-κB (NF-κB) in renal tubular epithelial cells (HK-2) stimulated by albumin and to explore the mechanisms of action. Method The HK-2 cells were incubated in the presence of albumin (5,15,30 mg/mL) with or without Ly294002 (an inhibitor of Akt). Expression of mRNA was analyzed by reverse transcription-polymerase chain reaction (RT-PCR).Expression of Akt and protein MCP-1 were assessed by Western blot. Electrophoretic mobility shift assay (EMSA) was used to detect the activation of NF-κB. q-test was used to evaluate the differences in means between groups. Results Compared with control group, the expression of MCP-1 mRNA remarkly increased. [Control group: 0.233 ±0.01; BSA(5 mg/mL) group: 0.285 ±0.04; BSA( 15 mg/mL) group:0.387 ± 0.02; BSA ( 30 mg/mL) group: 0.473 ± 0.05; BSA ( 30 mg/mL) + Ly294002 group: 0. 325 ±0.05, P ＜ 0.05 ]. The expression of MCP-1 protein in renal interstitum of operation group were remarkly increased too. [ Control group: 100 ± 15.1; BSA ( 5 mg/mL) group: 148 ± 19.3; BSA ( 15 mg/mL) group: 176±20.7; BSA(30 mg/mL) group: 263 ± 18.1; BSA(30 mg/mL) + Ly294002 group: 175 ± 18.0, P ＜0.05 ]. Albumin stimulated the expression of MCP-1mRNA and protein in a dose-dependent manner. Albumin remarkably increased the activity of NF-κB. Albumin enhanced the expression of Akt. Ly294002 inhibited albumin-induced the expression of NF-κB and partially decreased the level of MCP-1. Apositive correlation was noted between NF-κB activation and MCP-1 expression( r = 0.68 ,P ＜ 0.01 ). Conclusions Albumin-induces MCP-1 and NF-κB production via Akt signal pathway in renal tubular epithelial cells.

ObjectiveTo investigate the application of rapid immunohistochemical staining technique in intraoperative frozen section diagnosis of thyroid neoplasm.Methods MaxVision one-step rapid immunohistochemical staining technique was used to detect the expression of CK19,HBME-1,and Gal-3 in frozen section of papillary thyroid carcinoma(PTC)andthyroid benign lesions.MaxVision conventional immunohistochemistry of frozen remaining tissue was served as control.ResultsMaxVision one-step rapid immunohistochemical staining technique could be completed in 20 minutes.The positive localizations of three markers detected by rapid immunohistochemistry were similar to conventional immunohistochemistry, in general.The expression of CK19 was located in cytoplasm and cellular membrane.Gal-3 and HBME-1 were mainly detected in follicular luminal border and/or surface of papilla. The staining intensity in rapid immunohistochemistry was stronger than that in conventional immunohistochemistry. The positive rates of CK19,HBME-1,and Gal-3 by rapid immunohistochemistry in frozen sections were: 0 (0/28),10.7 ％ (3/28),0 (0/28),respectively,for benign lesions (nodular goiter,Hashimoto thyroiditis,thyroid adenoma); and 94.9 ％(37/39),92.3 ％ (36/39),92.3 ％ (36/39),respectively,for PTC.The expression of three markers between thyroid benign lesions and PTC had a significant difference (x2 =59.326,55.861,44.605,all P ＜ 0.001).In benign lesions,the rate of same case with two and more positive markers was 0,while in PTC it was 100 ％ and significantly different (x2 =67.000,P ＜ 0.05).ConclusionMaxVision one-step rapid immunohistochemical staining technique could be applied in intraoperative frozen section diagnosis.Detecting CK19,HBME-1,and Gal-3 expression in intraoperative frozen section has an auxiliary value for diagnosis of PTC.

The studies have shown that the genesis and development process of breast cancer is closely related with microRNAs (miRNAs).Multiple miRNAs are involved in the progress of the incidence of breast cancer,and can be used to assess the prognosis,clinical treatment of breast cancer,and to explore the resistance mechanisms.

Objective This research is to observe the treatment effects of hip bath and oxygen blowing on severe neonatal diaper rash.Methods 289 neonates with severe diaper rash were randomly divided into three groups.91 cases in the flat tube group,102 cases in the round tube group and 96 cases in the control group.Three groups of neonates were cleaned on the hips and perineuma after poops and then dried with wet tissues and Mupirocin Ointment.The control group was treated with the above-mentioned method.The oxygen blowing groups were treated with hip bath of 1:5000 chameleon solution twice a day.Blowing the hips with oxygen five minutes every time after hip bath.The method of blowing oxygen was that oxygen humidifying containers as normal oxygen aspiration facilities was not filled with water,whose oxygen flowing volume standed at 10 L/min and whose tube blew at the afflicted parts until being dry.The oxygen blower held the oxygen exit and blowed at the afflicted parts in the round tube group and the oxygen blower flattened the oxygen exit and blew at the afflicted parts in the fiat tube group.The treatment effects will be compared among the three groups four days later.Results The cure period of the round tube group was obviously shorter than that of the control group,and the cure period of the fiat tube group was remarkably shorter than that of the round tube group.The total effective rate in the round tube group was obviously higher than that of the control group and the total effective rate in the fiat tube group was obviously higher than that in the round tube group.The difference had a statistical significance.Conclusions The treatment effects for the severe neonatal diaper rash with hip bath and oxygen blowing are remarkable and the oxygen blowing effects with fiat tubes are better than those with round tubes.

Objective Queuing theory is the mathematical study of how waiting lines or queues are formed and dissipated o -ver time, which aims to work out the optimal design and optimal control of queuing systems based on the research of probability and regularity of various queuing systems .The aim of paper was to find out the maximum acceptable waiting time for outpatients in stomatol -ogy department and explore the rational allocation of dentists based on queuing theory model . Methods Questionnaires , worktime measurement and queuing theory model were applied to calculate indicators of queuing system in outpatient services of Stomatology De -partment , getting the maximum waiting time accpetable for patients and the reasonable number of dentists . Results The maximum acceptable waiting time for outpatients was 34.02 ±7.07 minutes, and it was reasonable to allocate 25 doctors in the morning and 16 doctors in the afternoon . Conclusion Applying queuing theory helps to optimize dentist number in outpatient services of Stomatology Department and provide scientific reference to improve medical efficiency .
