Objective To explore the changes of the levels of CA-125 antigen(CA125) and vascular endothelial growth factor (VEGF) in serum and peritoneal fluid in patients with endometriosis (EMT), and the relationship with EMT. Methods One hundred and twenty patients with EMT (EMT group)and 98 patients with uterine fibroids (control group) were enrolled in this study. The levels of CA125 and VEGF in serum and peritoneal fluid were detected by enzyme linked immunosorbent assay (ELISA), and the results were compared. Results The levels of serum CA125,VEGF in EMT group were significantly higher than those in control group:(40.31±11.14) kU/L vs.(24.71±9.19) kU/L,(59.75±6.87) ng/L vs. (36.38±8.12) ng/L, there were significant differences(P<0.05). The levels of serum CA125,VEGF inⅠ-Ⅱphase andⅢ-Ⅳphase in EMT group had no significant differences ( P>0.05). The levels of peritoneal fluid CA125,VEGF in EMT group were significantly higher than those in control group:(311.46± 107.29) kU/L vs.(158.17± 55.42) kU/L,(73.28 ±10.40) ng/L vs. (40.21 ±9.84) ng/L, there were significant differences (P<0.05). The levels of peritoneal fluid CA125,VEGF in Ⅲ-Ⅳ phase were significantly higher than those in Ⅰ-Ⅱ phase in EMT group:(387.41±70.91) kU/L vs. (308.42±81.21) kU/L, (69.22±7.13) ng/L vs. (55.44±8.23) ng/L, there were significant differences (P<0.05). In EMT group, the levels of CA125 and VEGF in serum were significantly lower those in peritoneal fluid:(40.31±11.14) kU/L vs. (311.46±107.29) kU/L, (59.75±6.87) ng/L vs. (73.28 ±10.40) ng/L, there were significant differences (P<0.05). Conclusions The levels of CA125 and VEGF in serum and peritoneal fluid are closely related to EMT. Peritoneal fluid in monitoring of EMT may be more sensitive and reliable than serum.

Objective:To discuss the therapeutic effect of pharmaceutical care for old patients with chronic obstructive pulmonary disease ( COPD) . Methods:Totally 192 patients diagnosed as COPD were randomly divided into 2 groups according to a random num-ber table, 100 cases in the experimental group and 92 cases in the control group. The control group was treated with the conditional therapy, and the experimental group was treated with pharmaceutical care additionally. The studieds on COPD assessment test ( CAT) , modified British medical research council ( mMRC) and the value of pulmonary function index ( FEV1% index) were carried out and compared between the two groups. Results:There was no statistically significant difference in the CAT score, mMRC classification and FEV1% index between the two groups on admission (P>0. 05), however, after the treatment, the CAT score and mMRC classifica-tion were decreased and FEV1% index was increased in the two groups, and there was statistical significance between them ( P <0. 05). The CAT score and mMRC classification in the experimental group were lower and FEV1% index was higher than that in the control group(P<0.05). Compared with the medication errors(n=13, 14.13%) and incidence of adverse drug reactions(n=5, 5. 43%) in the control group, the medication errors(n=2, 2. 0%) and incidence of adverse drug reactions (0%) in the experimental group were significantly decreased. Conclusion:Clinical pharmacists provide effectively pharmaceutical care, which can significantly improve the clinical therapeutic efficacy in old patients with COPD.

Objective To detect the expression and effect of human tumor necrosis factor related apoptosis-inducing ligand (hTRAIL) in vivo,by using a novel double expressing adenoviral vector encoding hTRAIL and firefly luciferase ( luc ) gene ( ad -luc-hTRAIL),in which luc was used as reporter gene.Methods Lung cancer A549 cell xenografts in 16 nude mice models were established in subcutaneous inoculation way,the adenovirus vectors ( ad-luc-hTRAIL,ad-hTRAIL,ad-luc) and phosphate buffer saline (PBS) (n =4) as control were injected into tumor respectively.The size of the tumor was measured at different time points (4,7,10,14,21,28 d)after injection.The activity of luciferase in surface of the tumor was detected in vivo by using high-sensitivity cooled-charged coupled device(CCD) camera.The expression of hTRAIL was demonstrated by immunohistochemistry staining after sacrificing the animals at different time points,and immunohistochemical scores (IHS) were measured. The apoptosis rate of tumor cells was detected by using TUNEL and calculated. Analysis of variance,the paired t test and linear correlation analysis was used for the statistics. Results The growing speed of tumour xenografts was more slowly in ad-luc-hTRAIL and ad-hTRAIL groups than PBS group (t =2.71,2.72,P ＜ 0.05 ).The tumor volumes of ad-luc-hTRAIL,ad-hTRAIL,ad-luc and PBS groups 28 days after injection were (208.4 ± 42.3 ),( 181.5 ±23.9),( 403.1 ± 54.0 ) and ( 427.0 ± 59.3 ) mm3, respectively. There was no significant difference between ad-luc group and PBS group(t =2.07,P ＞ 0.05).The expression of luciferase in ad-luc-hTRAILgroup reached its peak at 7th day ( 1.37 ± 1.04),and then decreased quickly.The IHS and apoptosis rate in ad-luc-hTRAIL and ad-hTRAIL groups reached their peaks at 7th day,the peak values of IHS were 6.25 ±2.06 and 6.5 ± 2.89,the peak values of apoptosis rate were (60.75 ± 8.06 ) ％ and ( 61.50 ± 8.47 ) ％,respectively.The amount of luciferase expression ( absolute number of photons detected by CCD camera)was linear positive correlated with IHS and apoptosis rate ( rphotons/IHs =0.942,rph /rate =0.842,rIHs/rate =0.887,P ＜ 0.05 ).Conclusion The target gene hTRAIL can be transfected into lung cancer A549 cell xenografts nude mice models efficiently with a high level expression,and the therapeutic effect of hTRAIL can be monitored by detecting the expression of luc.

Objective To study the bone turnover and its related molecular mechanism in STZ-induced diabetic rats. Methods Of 30 male SD rats studied, 15 were induced diabetics by intravenous injection of streptozotocin (50 mg/kg)and fed for 8 weeks. After the sacrifice of both the diabetic and control groups, serum Ca, P, alkaline phosphatase (ALP), and osteocalcin were determined, and 24 h urinary Ca and urinary cross-linked N-telopeptide of type Ⅰ collagen (NTx)and creatinine (Cr)ratio were also determined. The left tibia was dissected for bone histomorphometry analysis. Right femur and lumbar vertebrae (L1-L4) were reserved for bone mineral density (BMD) determination. The right tibia was separated for the study of bone tissue RANKL/osteoprotegerin, Core binding factor 1 (Cbfa1) ,osterix and osteocalcin mRNA level which was performed by real-time quantitative reverse transcription polymerase chain reaction assay. Results No significant difference was found in serum Ca, P, and ALP levels between 2 groups of rats. ST-Z-induced diabetic rats were characterized by extreme hyperglycemia, marked weight loss, polyuria, and hypercalciuria. A low-turnover osteopenia was evidenced in diabetic rats by decreased BMD in both femur [(0. 099±0.013) vs (0. 139 ± 0.013 g/cm~3) , P < 0.01] and lumbar vertebrae [(0. 107±0.011)vs (0. 149±0.009) g/cm~3, P<0.01] , reduced serum osteoealcin level [a marker of formation, (3.03±0.52) vs (6. 18±0.71) ng/ml ,P<0. 01]) ,decreased urine NTx/Cr ratio [(5. 67±0.86) vs (5.23±0.98) nmol/g Cr, P<0. 05], decreased trabeeular volume and thickness, and reduced bone label surface and bone formation rate [(0. 44±0. 11) vs (0. 78±0. 14) μm/d,P<0. 01] by bone dynamic study. The RANKL/ osteoprotegerin [(0.57±0.11)vs (0.89±0.13) ,P<0.01] ,osterix [(1.93×10~(-4)±0.65×10(~-4))vs (4.19×10~(-4)± 0.71×10~(-4)) ,P<0.01] ,Cbfa1 [(26.68×10~(-4)±6.53×10~(-4))vs (37.21×10~(-4)±7.14×10~(-4)) ,P<0.01] ,and osteocalcin [(2.25×10~(-4)±1.19×10~(-4))vs (3.43×10~(-4)±1.63×10~(-4)) ,P<0.01] mRNA expressions were declined in the bone tissue of the tibia in the ST-Z-induced diabetic rats, as compared with the control. Conclusion A low-turnover osteopenia is evidenced in STZ-induced diabetic rats by significant decrease of both osteoclastic marker(RANKL/ osteoprotegerin)and osteoblastic marker (osterix ,Cbfa1 ,osteocalcin)mRNA levels in tibia.
