Objective To elucidate the mechanism of accelerated apoptosis of monocytes in patients with lupus nephritis (LN). Methods 17 LN patients were enrolled in the study and 15 healthy volunteers were selected as controls. The expression of Faa and Fas ligand (FasL) was examined by immunofluorescent staining and flow cytometer analysis. The apoptosis and survival rate of monocytes cultured in vitro with human FasL (rHu-FasL) was analyzed by flow cytometer analysis and 5-diphenyl tetrazolium bromide (MTT) staining, respectively. Results Faa expression on monocytes was significantly higher in LN patients than that in healthy subjects. There was no difference of monocytes Fas expression between active LN patients and silent LN patients. There was no detectable FasL expression on monocytes from both LN patients and healthy controls. When monocytes cultured in vitro with rHu-FasL, there was a significantly increasing apoptosis and a decreasing survival rate of monocytes in LN patients as compared to healthy controls. Conclusion The up-regulated expression of functional Fas on monocytes may contribute to the accelerated apoptosis of monocytes in LN patients.

Objective To study the expression of survivin and its relationship with the proliferative activity in hepatocellular carcinoma.Methods Using immunohistochemistry ABC methods, the expression of survivin and PCNA were evaluated in 31 hepatocellular carcinoma, 8 cirrhosis of liver and 4 normal livers tissues.Results No expression of survivin were detected in normal livers and cirrhosis of liver. In contrast, survivin protein was expressed in 19 of 31 patients with HCC(61.3%). When compared with normal livers and cirrhosis of liver, hepatocellular carcinoma had significantly more frequencies of survivin expression(P

Objective To study the degradation of Rhizoma Typhonii polysaccharide with sulfuric acid under the normal and ultrasonic condition. Methods The orthogonal test table L9(34) was used to optimize 4 factors including acid concentration, reaction time, reaction temperature and ultrasonic power, with the yield of the low-molecular-weight polysaccharide as the index. Results The optimal conditions of discomposing Rhizoma Typhonii polysaccharide with sulfuric acid were 10% sulfuric acid, 100 ℃ for 2 h under the normal condition,and the yield of low-molecular-weight polysaccharide was 36.17%. Under the ultrasonic condition, the optimal conditions were 150 W of the ultrasonic power, 5% sulfuric acid, 40 ℃ for 1 h, and the yield was 44.63%. Conclusion The degrading yield of the low-molecular-weight polysaccharide can be increased under ultrasonic condition with sulfuric acid.

Objective To investigate the relationship of nerve growth factor (NGF) between serum and follicular fluid in patients with polycystic ovary syndrome (PCOS), and its effect on pregnancy outcomes. Methods From December 2011 to November 2012, 65 PCOS patients suffered with in vitro fertilization-embryo transfer (IVF-ET) were included in PCOS group and 31 non-PCOS patients with IVF-ET were used as control group. The expressions of NGF in serum and follicular fluid were detected by ELISA on the injection day of chorionic gonadotropin (HCG). The expression levels of NGF in serum and follicular fluid were compared between PCOS group and control group. Results The NGF levels in serum[(14.38±0.42) ng/L] and follicular fluid[(9.61±0.49)ng/L] were significantly higher in PCOS group than those of control group[(11.39±0.38) ng/L and (7.55 ± 0.40)ng/L]. In PCOS group, NGF levels in serum [(14.22 ± 0.35)ng/L] and follicular fluid [(9.30 ± 0.31)ng/L] were significantly lower in pregnant group than those of non-pregnant group[(14.51±0.43)ng/L, (9.86±0.46)ng/L, P<0.01]. Conclusion The increased levels of NGF in serum and follicular fluid of PCOS patients contribute to the pathogenesis of PCOS. The high expression of NGF in serum and follicular fluid may be harmful to pregnancy in PCOS patients.

Objective To study the test-retest reliability in quantitative measurement of proprioception using Tecnobody rehabilitation system.Methods Nine healthy volunteers [4 males,5 females,averaged age (22.8 ±0.68) years] participated in three consecutive measurements on both feet by using Tecnobody rehabilitation system for computerized proprioceptive assessment.Standard error of measurement(SEM),correlation coefficient and intraclass correlation coefficient(ICC) obtained from the three consecutive measurements were used to analyze the Timeused in each measuring session,and the average track error (ATE) of the measurements.ResultsSEM values of Time in left foot and right foot were 3.07 ～ 3.83 and 6.65 ～ 8.44 respectively.ATE values in left foot and right foot were 1.33 ～ 1.97 and 1.39 ～ 1.91 respectively.The Time and ATE correlation coefficients of left foot / right foot were 0.919/0.6 and 0.808/0.831,respectively.The Time ICC values were 0.893/0.639 for left foot / right foot,respectively ; and the ATE ICC values were 0.716/0.734 for left foot / right foot,respectively. Conclusion The Tecnobody rehabilitation system provided a fairly good reliability in both relative andabsolute values in quantitative evaluation of proprioception in the feet.These data in a larger amount may be useful for setting up variables and the standard values of the local population for reference in proprioceptive rehabilitation.

Objective To investigate the expression of phosphorylated protein kinase B1 (pAkt1) and human telomerase reverse transcriptase (hTERT) in ovarian epithelial carcinoma (EOC) and its relationship with prognosis, and to analyze the correlation between pAkt1 and hTERT expression. Methods 92 patients with EOC in Tangshan Gongren Hospital from January 2012 to December 2016 were selected. The expressions of hTERT and pAkt1 proteins were detected by immunohistochemistry. The relationship between the expressions of pAkt1 and hTERT proteins and their relationship with clinical prognosis were analyzed. Results Of the 92 patients with EOC, 68 cases (73.9 %) had positive expression of pAkt and 52 cases (56.5 %) had positive expression of hTERT. There was no significant correlation between expressions of pAkt1 and hTERT proteins in EOC (r= 0.284, P= 0.633). The expressions of pAkt1 and hTERT proteins were not related with age, tumor pathology type and the International Federation of Gynecology and Obstetrics (FIGO) staging (all P> 0.05), but had significant association with tumor pathology differentiation (χ2= 2.694, P= 0.005; χ2=2.284, P=0.018). The disease-free survival of patients with both pAkt1 and hTERT positive was shorter than that of the other groups (P= 0.013). Conclusion The prognosis of EOC patients with high expression of pAkt1 and hTERT proteins is poor.

BACKGROUND:The position of median and radial nerves corresponding to elbow is usual y estimated by macroscopical measurements, but there are big data errors when the elbow is bent. OBJECTIVE:To measure and analyze the impacts of elbows in different positions on median and radial nerves under X-ray. METHODS:Ten fresh frozen upper limb specimens were selected. The distance of median and radial nerves to the osseous marks inside the elbow was measured when the elbow was in extension, extension-half pronation, bent at flexion 90 degrees and bent at 90 degrees with the injection of normal saline into the joint capsule, respectively. RESULTS AND CONCLUSION:The positions of median and radial nerves were not influenced when the elbow was in extension or in extension-half pronation (P>0.05). The distance of median and radial nerves to the osseous mark of the elbow was significantly lengthened when the elbow was moved from from extension to was bent at 90 degrees (P<0.05). The intra-articular injection of normal saline when the elbow flexion 90 degrees significantly elongated the distance of median and radial nerves to the osseous mark of elbow (P<0.05). These results suggest that the elbow in different positions can induce the displacement of median and radial nerves. In addition, the distance between median, radial nerves and the osseous marks of the elbow is obviously lengthened when the elbow is in flexion with intra-articular injection of normal saline.

OBJECTIVE To investigate drugresistance and clinical distribution characteristics of Staphylococcus strains isolated from inpatients.METHODS The meticillin-resistance and drug-resistance of the Staphylococcus strains isolated from the clinical specimens of the inpatients in our hospital between 2003 and 2005 were tested.RESULTS Totally 768 Staphylococcus strains were mainly isolated from sputum,blood,pus and wound secretion.The main clinical wards were from pediatrics,ICU,tumor chemotherapy departments.The age of these inpatients were mainly over 60 years old(48.7%) and less than 13 years old(33.2%).Two hundred and ninetyStaphylococcus aureus strains(37.8%)and 478 coagulase-negative Staphylococcus strains(62.2%)were included.The isolated rates of meticillin-resistant S.aureus and meticillin-resistant coagulasenegative Staphylococcus were 74.8% and 89.1%,respectively.CONCLUSIONS Infections of Staphylococcus are increased year by year among inpatients.There are high rates of meticillin-resistant strains.It is very important to monitor infections of Staphylococcus,to control the source of infections,to interrupt their spread and to protect impressionable inpatients,in order to prevent infections of Staphylococcus actively.
