Objective To improre typieal proeedure of UPPP,increase clinical effects and deerease complioations caused by the operation.Methods Twenty eight patients with obstructive sleep apnea syndrome who had been confirmed by PSG in our hospital from 2003 to 2005 were involved in this study.1)improving stripping method:the fat and tonsil were removed by electric knife.2)improving molding method:the muscle of uvula was maitained,but the fat was removed;mucous and the tissue under it were double-layer sutured.3) the data before and 6 months after UPPP were analyzed by questionnaire and polysomnography(PSG)detection.Result No fissuration occurred.The distance between soft palate and posterior wall was 3?0.6 before operation and it was 6?0.8 6 months after operation.The effect is 100% based on the questionnaire investigation and PSG detection.Conclusions 1)Hemostasis of electric knife was reliable;2)Double-layer suture of mucous and the tissue under it can avoid hemorrhage and insure molding of pharyngeal cavity;3)The results of the uvula preservation can improve the effect of the UPPP by increasing the nasopharyngeal and oropharyngeal cavity,and avoiding velopalatal insufficiency.

Objective To discuss whether the separating block of sensory nerve with acupoint-injection and epidural analgesia by ropivacaine during labour.Methods Ninty full term primigravidae with ASAⅠ～Ⅱwere randomly divided into 3 groups:group E(n = 30),group C(n = 30)and group A(n = 30).When the external cervi- cal os was dilated to 3cm,group A:acupiont-injection to Ci Liao;group E:epidural analgesia with 0.075% ropiva- caine and fentanyel 2?g/ml;group C:combining group A and group E except fentanyel 2?g/ml.Level of pain(VAS scores),degree of sensory and motor block,the mode of delivery,the progress of labour and side effects were recorded and compared.Results The level of pain(VAS scores)in group A was higher than that of group C and group E,and there were no significant differences in group C and group E,Bur there were some side effects discovered in group E. There was no significant differences of the mode of delivery in the groups.Conclusion The method that acupoint- rejection combined with epidural analgesia by 0.075% ropivacaine is effective and has no side effects for labour.

OBJECTIVETo explore the influence of nonylphenol (NP) on the neural behavioral development of filial generation rats exposed via placenta.

METHODSOn the first day of the pregnancy, the SD rats were divided into four groups, and orally administered with NP at doses of 0, 50, 100 and 200 mg/kg on gestational day 9 approximately 15 respectively. The offspring rats of each groups were examined to observe the impact of NP on the early physiological, neurobehavioral development. The changes of filial generation body weight (from generation day 1 to 28) were measured. Brain tissues were stained with Hematoxylin-eosin and Congo red to observe with optical microscope.

RESULTSIn contrast to the control group, the early physiological markers (pinna detachment, hair growth, tooth growth and eye opening) and the early neurobehavioral development indices (surface righting, air righting, acoustic startle and visual placing) were significantly delayed in the groups of NP 200mg/kg dose (P < 0.05). The developing time of physiological markers decreased from (4.5 +/- 0.8, 5.2 +/- 0.8, 12.7 +/- 1.4, 16.0 +/- 1.7) d to (3.6 +/- 0.5, 3.6 +/- 0.5, 11.1 +/- 1.1, 12.7 +/- 1.3) d while neurobehavioral developing time decreased from (6.5 +/- 0.8, 11.3 +/- 0.5, 11.2 +/- 1.0, 20.2 +/- 1.0) d to (5.1 +/- 0.4, 8.3 +/- 0.5, 9.3 +/- 0.5, 9.3 +/- 0.5) d (P < 0.05 or P < 0.01). The body weights of filial generation rats were decreased obviously from 1 st day to 28th day. Histopathological examination displayed that hippocampal neurons had congestion and oedema in the group of 100, 200 mg/kg dose.

CONCLUSIONExposures to NP during gestation might impair the neurobehavioral development of F1 rats significantly.

OBJECTIVETo evaluate the efficacy and analyze the prognostic factors of sorafenib treatment in patient with unresectable primary hepatocellular carcinoma (HCC).

METHODSDuring the period from December 2005 to March 2009, 50 patients with unresectable primary HCC of Child-Pugh status A were treated with sorafenib (400 mg, Bid). The tumor response was evaluated with CT or MRI imaging every 6 - 8 weeks according to the RECIST criteria. The overall survival (OS) and time to progression (TTP) were defined as the time from administration of sorafenib to the death or the last follow up and were evaluated by Kaplan-Meier method.

RESULTSThere was no PR or CR, but 28 patients (56.0%) achieved stable disease. The median follow up time was 15 months with a median OS of 14 months and median TTP of 4 months. The common adverse events were dermal reaction (68.0%, 34/50), diarrhea (52.0%, 26/50), hypertension (4.0%, 2/50), hair loss (14.0%, 7/50), myelosuppression (16.0%, 8/50), and liver dysfunction (20.0%, 10/50). However, most of the drug-related adverse events were grade I-II and reversible. The patients with lower tumor burden and without distant metastasis had better prognosis.

CONCLUSIONSoafenib is effective for unresectable primary HCC with tolerable toxicity. Tumor stage is a predominant prognostic factor.

OBJECTIVETo investigate the expression level of S100A6 mRNA in MM and to its clinical significance, and to evaluate its significance.

METHODSThe expression level of S100A6 mRNA in MM patients was determined by real time quantitative PCR(RQ-PCR), and its relationship with the clinical features and outcomes of patients was analyzed by statistic method.

RESULTSS100A6 mRNA was detected in 20 MM patients. Compared with normal persons, the S100A6 mRNA expression in MM patients was higher. In different groups, the S100A6 mRNA expression in MM patients of 3 stages was higer than that in patients of 1 and 2 stages. MM patients with higher S100A6 mRNA expression had poor prognosis and higer extramedullary metastasis rate.

CONCLUSIONThe high expression of S100A6 mRNA is associated with poor prognosis and may be a prognostic molecular marker of MM.
