BACKGROUND:Severe knee pain after total knee arthroplasty is an important factor for the poor recovery of knee function after replacement. How to give a satisfactory postoperative analgesia scheme is currently a hot research. OBJECTIVE:To explore the clinical effects of different analgesic program methods on postoperative pain and functional recovery in patients undergoing total knee arthroplasty. METHODS:From March 2010 to February 2014, 60 patients with unilateral knee arthroplasty were randomly divided into three groups:epidural analgesia group, intravenous analgesia group, and continuous femoral nerve block analgesia group. 20 patients in each group received corresponding postoperative analgesia. Visual Analogue Scale score before replacement, 1, 6, 24, 48 and 96 hours after replacement, the recovery of range of motion at 24, 48 and 72 hours after replacement, KSS score of the knee and adverse reactions after replacement were recorded and compared in each group. RESULTS AND CONCLUSION:Compared with the preoperative data, Visual Analogue Scale score was reduced in continuous femoral nerve block analgesia group at 1, 24, 48 and 96 hours after replacement (P<0.05). The recovery of range of motion was best in the continuous femoral nerve block analgesia group, fol owed by epidural analgesia group, and it was poorest in the intravenous analgesia group (P<0.05). Compared with the preoperative data, postoperative KSS scores increased at 1 and 3 months after replacement in the three groups (P<0.05). Compared with the continuous femoral nerve block analgesia group, knee joint function score was decreased in the intravenous analgesia group (P<0.05). Results verified that continuous femoral nerve block analgesia had good overal effects, helped the recovery of postoperative joint function, and was safe and reliable.

Purpose To investigate the imaging features of breast phyllodes tumor on mammography(MG),ultrasound(US) and pathology, correlated with its clinical manifestation.Materials and Methods Twelve cases of pathologically confirmed breast phyllodes tumors were examined by US and MG. The imaging findings were retrospectively analyzed. Results Of the 12 cases of breast phyllodes tumors, 6 were benign, 3 were malignant and 3 were borderline. MG predicted 3 breast phyllodes tumors, 3 breast carcinomas and 6 adenomas. US predicted 2 phyllodes tumors, 8 breast masses and 2 adenomas. Conclusion The imaging findings of phyllodes tumors on MG and US are characteristic but not specific. Combined application of both US and MG are helpful for early detection but can not differentiate its malignancy which is determined by pathology.

Objective To investigate the anxiety status of male partner involved in induced abortion and to analyze influencing factors related.Methods Male partners of the patients undergoing induced abortion in the gynecology and obstetrics department of a hospital in Kunming in April and May in 2015 were selected and a questionnaire survey was conducted.Self-rating Anxiety Scale (SAS) was used to measure the anxiety status and SPSS 17.0 was used for statistical analysis.Results A total of 53 out of 205 male partners were found to have anxiety symptoms (25.9％),with 44 cases of mild anxiety (21.5％),8 cases of moderate anxiety (3.9％) and 1 case of severe anxiety (0.5％).The main related risk factor was times of pregnancy (OR=3.35) while the protective factors were level of education (OR =0.60),times of induced abortion (OR =0.20) and age (OR =0.32) Conclusion When abortion occurs,the male partner's anxiety appears,mainly with mild and moderate one,and female's emotion are also affected.It is important to strengthen health education and popularize contraceptive knowledge so as to reduce the incidence of anxiety.

Objective To investigate the value of ultrasound contrast in differential diagnosis of liver alveolar hydatid disease and hepatic malignant tumor.Method Totally 36 cases of liver alveolar hydatid disease and 31 cases of hepatic malignant tumor were retrospectively analyzed,who visited the Ultrasound Department of Qinghai Red Cross Hospital from March 2010 to September 2013,the performance characteristics of gray-scale ultrasound and contrast-enhanced ultrasound (CEUS) on hepatic malignant tumor and liver alveolar hydatid disease were compared.Results Gray-scale sonography of 36 liver alveolar hydatid diseases showed clear boundary,heterogeneous hypoechoic nodules,and the maximum area was (5.06 ± 2.46) cm2 in 49 lesions;gray-scale sonography of 31 hepatic malignant tumors showed unclear boundary,hypoechoic nodules,and the maximum area was (7.29 ± 5.83) cm2.CEUS of liver alveolar hydatid disease showed non-enhancement in three phases,and rim enhancement was seen synchronized with the liver parenchyma.CEUS of hepatic malignant tumor showed hyperenhancement in arterial phase,equal-enhancement or hypo-enhancement in portal phase and delayed phase,and abnormal perfusion areas were clear.Conclusion Liver alveolar hydatid disease is different in the performance of CEUS from hepatic malignant tumor,CEUS has a great value in the differential diagnosis of liver alveolar hydatid disease and hepatic malignant tumor.

I uptake of thyroid and color Doppler flow imaging (CDFI) of superior thyroid artery (STA) were performed in 20 patients with Graves′ disease (GD) and 19 patients with other causes of hyperthyroidism. Maximum velocity and diameter of STA in patients with GD were much higher than those in non-GD group. CDFI of STA seems to be a useful tool in differential diagnosis of hyperthyoidism.

OBJECTIVETo investigate the effect of miRNA-101 on the expression of the enhancer of zeste homolog 2 (EXH2) in human androgen-independent prostated cancer LNCaP cells.

METHODSWe divided LNCaP cells into a blank control, a negative control, and a miRNA-l01 transfection group, constructed the vector by transfecting synthetic miRNA-101 mimics into the LNCaP cells, and evaluated the efficiency of transfection by fluorescence microscopy. Then we determined the expression level of EZH2 mRNA by qRT-PCR in the three groups of cells and that of the EZH2 protein in the negative control and transfection groups by Western blot.

RESULTSGreen fluorescence signals were observed in over 70% of the LNCaP cells in the transfection group after 24 hours of transfection. At 72 hours, the expression of miRNA-101 was significantly upregulated in the transfected cells (P < 0.01), that of EZH2 mRNA was remarkably lower in the transfection group (0.01 ± 0.10) than in the blank control (0.95 ± 0.40) and negative control (0.86 ± 0.30) groups (both P < 0.01), and that of the EZH2 protein was increased in the negative control but decreased in the transfection group with the extension of culture time.

CONCLUSIONmiRNA-101, with its inhibitory effect on the expression of EZH2 in LNCaP cells, is a potential biotherapeutic for prostate cancer.

Background To investigate the expression of the early growth response gene-1 ( Egr-1 ) mRNA after focal cerebral ischemia / reperfusion in rats.Methods Ten healthy male SD rats weighing 200 ～ 250 g were used to create model of focal cerebral ischemia. The expression of Egr-1 after focal cerebral ischemia/reperfusion in rats was determined using in situ hybridization and RT-PCR.Results (1) The result of the in situ hybridization: A trace amount of Egr-1 mRNA expressed in the neurons and the glial cells in the sham operated group. The expression of Egr-1 mRNA at the ischemic side increased dramatically following ischemia and reached peaks after 4 hours' reperfusion. Egr-1 expression started to subside following 22 hours' reperfusion and further decreased following 166 hours' reperfusion, which was still significantly higher than that in the sham operated group. (2) The result of RT-PCR: The expression of Egr-1 mRNA at the ischemic side was significantly higher than that in the sham operated group at all time points after ischemia/reperfusion in the rats(P ＜0. 01). Expression of Egr-1 increased 2 h after ischemia and reached the peak 4 h following reperfusion, and then decreased dramatically at 46 h after reperfusion which was still higher than that in the sham operated group (P ＜ 0. 01). As the ischemia/reperfusion period prolonged, the expression of Egr-1 mRNA increased gradually, but still detectable even 166 h following reperfusion. The expression of Egr-1 was significantly higher than that in the sham operated group at all time points (P ＜0. 01).Conclusions The expression of Egr-1 mRNA increase in the neurons and the glial cells after ischemia/reperfusion, which may have protective effects on ischemic brain tissues.

The purpose of this study was to evaluate the roles of different housing environments in neurological function,cerebral metabolism,cerebral infarction and neuron apoptosis after focal cerebral ischemia.Twenty-eight Sprague-Dawley rats were divided into control group (CG) and cerebral ischemia group,and the latter was further divided into subgroups of different housing conditions:standard environment (SE) subgroup,individual living environment (IE) subgroup,and enriched environment (EE) subgroup.Focal cerebral ischemia was induced by the middle cerebral artery occlusion (MCAO).Beam walking test was used to quantify the changes of overall motor function.Cerebral infarction and cerebral metabolism were studied by in vivo magnetic resonance imaging and 1H-magnetic resonance spectra,respectively.Neuron necrosis and apoptosis were detected by hematoxylin-eosin and TUNEL staining methods,respectively.The results showed that performance on the beam-walk test was improved in EE subgroup when compared to SE subgroup and IE subgroup.Cerebral infarct volume in IE subgroup was significantly larger than that in SE subgroup (P＜0.05) and EE subgroup (P＜0.05) on day 14 after MCAO.NAA/Cr and Cho/Cr ratios were lower in MCAO groups under different housing conditions as compared to those in CG (P＜0.05).NAA/Cr ratio was lower in IE subgroup (P＜0.05) and higher in EE subgroup (P＜0.05) than that in SE subgroup.NAA/Cr ratio in EE was significantly higher than that in IE subgroup (P＜0.05).Cho/Cr ratio was decreased in MCAO groups as compared to that in CG (P＜0.05).A significant decrease in normal neurons in cerebral cortex was observed in MCAO groups as compared to CG (P＜0.05).The amount of normal neurons was less in IE subgroup (P＜0.05),and more in EE subgroup (P＜0.05) than that in SE subgroup after MCAO.The amount of normal neurons in EE subgroup was significantly more than that in IE subgroup after MCAO (P＜0.05).The ratio of TUNEL-positive neurons in EE was significantly lower than that in SE subgroup (P＜0.05) and IE subgroup (P＜0.05).Correlation analysis showed that the beam walking test was negatively correlated with NAA/Cr ratio (P＜0.05).Cerebral infarct volume was negatively correlated with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.01).The amount of normal cortical neurons was positively correlated with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.05).The TUNEL-positive neurons showed a negative correlation with both NAA/Cr ratio (P＜0.01) and Cho/Cr ratio (P＜0.01).This study goes further to show that EE may improve neurological functional deficit and cerebral metabolism,decrease cerebral infarct volume,neuron necrosis and apoptosis,while IE may aggravate brain damage after MCAO.
