Objective To investigate the effects of polyi:c on angiogenesis in mouse prostate carcinoma tissue and their possible mechanisms.Methods Mouse prostate carcinoma models were randomly divided into two groups according to tumor weight:control group and polyi:c group.After treatment for 7 times,the mice were sacrificed and the tumor tissues were cut for weighing,calculating the tumor inhibitory rate and tumor index.Hematoxylin-eosin staining and immunohistochemical staining were performed to observate the morphological changes of prostate carcinoma tissues,distribution of vasa and expressions of vascular endothelial growth factor (VEGF) and endothelial nitric-oxide synthase (eNOS).Results In polyi:c group,the mean tumor inhibitory rate was 67.85% and the tumor index was(5.42?0.17)%;in control group,the tumor index was(14.45?1.06)%; there was significant differences between polyi:c group and control group( P

Objective To improve the understanding of drug-induced lupus (DIL) and the differences from systemic lupus erythematosus (SLE).Methods Clinical manifestation and treatment of patients with definite DIL were retrospectively analyzed.Results Six patients with DIL were enrolled in this study,including 4 females and 2 males.Two patients were diagnosed after receiving interferon,one after soluble tumor necrosis factor receptor fusion protein,one after propylthiouracil,one after penicillamine,and one after levofloxacin.High titer of antinuclear antibody was identified in all six patients,including 3 with positive anti-dsDNA antibody.One patient had positive anti-Sm antibody.One patient had positive anti-RNP antibody.One patient had anti-nucleosome antibody.One patient had anti-histone antibody.One patient had antimitochondrial antibodies-M2,and one patient had anticardiolipin antibodies.Conclusion Patients with DIL are not as severe as those with SLE.After cessation of suspected drugs and administration of standard treatment,the clinical outcome of DIL is satisfying.

Objective To explore the association between waist-to-height ratio (WHtR) and dyslipidemia in Chinese adults and to find out an optimal threshold of WHtR for predicting dyslipidemia.Methods A total of 221 270 adults from 4 health checkup centers nationwide were selected by using cluster random sampling method.Height,body weight,waist circumference (WC),total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol(LDL-C) were measured.Body mass index (BMI) and WHtR were then calculated.The area under the receiver operating characteristic curve(AUC) was analyzed and optimal cutoffs were estimated by maximizing the sums of sensitivity and specificity.Results WHtR showed the largest AUCs in the participants with higher TC,TG and LDL-C,followed by increased WC and BMI.In male and female,the optimal thresholds of WHtR,WC and BMI for predicting dyslipidemia were 0.49-0.50 and 0.47-0.49,83-85and 73-76 cm,and 24-25 and 22-23 kg/m2,respectively.Conclusion WHtR may be superior to WC and BMI for predicting dyslipidemia,and an unisex cutoff of 0.5 should be recommended.

Aim To investigate the effects of polyI:C on angiogenesis in mouse prostate carcinoma and its mechanisms.Methods Prostate carcinoma bearing mice were randomly divided into two groups according to tumor volume:contrl group and polyI:C group.After seven times′treatment,the mice were sacrificed.The content of NO in tumor was measured by nitric oxide assay kit.Tumor tissues were partly performed hematoxylin-eosin staining to observe morphological changes and distribution of vasa.Immunohisto chemical staining was used to observe the expression of VEGF,eNOS and AQP1.Results The content of NO in polyI:C group and the control was(1.22?0.77)?mol and(8.73?5.34)?mol respectively,and there was significant difference between two groups(P

Multi-components compatibility theory of Chinese materia medica (CMM) has been more and more mature and perfect, because of the efforts of many scientific and technological workers for nearly 20 years. Omics, compatibility, and fingerprint are the three key words of the multi-components compatibility theory. Namely in multi-components compatibility theory, modern "omics" and traditional "compatibility" are closely combined through "fingerprint". The modernization of CMM has developed to such a stage that the fingerprint (especially IGD 13C-NMR coupling fingerprint) method could be used to study morden CMM under the guidance of multi-components compatibility theory.

Objective:To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty.Methods:From April to September 2016,patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed,and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery.Numeric pain rating scales (NPRS)pain scores in rest and activity 2,6,12,24 and 48 h after surgery were collected,and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed.Opioids consumption and anesthesia related adverse effects were also recorded.Results:In the study,40 patients were enrolled,with 20 patients in each group,male ∶female =7 ∶ 33,the age:(63.8 ± 10.1) years,and the body mass index (BMI):(28.5 ± 3.5) kg/ m2.The general conditions were comparable between the two groups.Though the rest pain 2 h after surgery [ACB =0.0(0,6),FNB =3.0(0,5),P=0.004] and activity pain 12 h post operation [ACB =3.0(3,0),FNB =5.5(0,10),P =0.004] were lower in ACB group compared with FNB group,there was no statistical difference in the other pain checking points between the two groups.The quadriceps strength 24 h and 48 h after surgery were (85.3-± 27.6) N and (80.0 ± 30.1) N in ACB group,(69.0 ± 29.4) N and (64.4 ± 32.0) N in FNB group,both of them were declined by time.The exact data were higher in ACB group,however,there was no statistical difference between the two group by repeated measurements variance analysis(F =2.703,P =0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h.And among them,three patients acquired once dolantin in ACB,two in FNB,from 24 to 48 h postoperation.There were five patients who suffered nausea postoperation in ACB group,and one who reported xerostomia.Four patients in FNB had nausea with vomiting,and three experienced xerostomia.Deep vein thrombosis appeared in 2 patients in FNB group,but no one in ACB group.Conclusion:Continuous ACB is not superior in pain control after TKA compared with FNB,and the quadriceps strength could be reserved more by this method,which performed early benefits in fast rehabilitation.

Objective To investigate the clinical and pathological features of eosinophilic diseases with cardiac involvement Methods We analyzed the clinical and cardiac pathological data of 7 patients with eosinophilic diseases with cardiac involvement under endomyocardial biopsy or autopsy.Results Seven patients (5 male, average age 51 years) were enrolled.Four patients were diagnosed as idiopathic hypereosinophilic syndrome and three were Churg-Strauss syndrome.Peripheral blood eosinophila count increased significantly in all patients.Cardiac involvement included angina pectoris, myocardial infarction, heart failure, presyncope and sudden death.Electrocardiogram showed cardiac ischemia, bundle branch block and third degree atrioventricular block.Echocardiography suggested ventricular and atrial enlargement, decreased ventricular systolic function, pulmonary hypertension, valvular prolapse and insufficiency and endocarditis.Pathology displayed infiltration of eosinophils, formation of granulomata, necrotizing vasculitis, myocardial necrosis and endomyocardial fibrosis in heart.Coronary artery could be also affected and led to myocardial infarction.Conclusions Cardiovascular complications of eocinophilic diseases are a major source of morbidity and mortality in these disorders.The manifestations are multiple and early recognition and treatment with steroid and immunosuppressant can improve prognosis.

Objective:To evaluate the efficiency of the tibial coronal alignment after total knee arthro-plasty with the extramedullary cutting system guided by the tibial tubercle and anterior tibial tendon,and to discuss the potential risk factors for the postoperative malalignment.Methods:A retrospective study of 212 primary unilateral TKA surgeries (in 188 patients)in our hospital between June to December in 2014 had been analysed.All the cases were performed by one surgical group.An extramedullary tibial cutting guide system had been used,with a landmark of one third inner-medial tibial tubercle as a proxi-mal anatomy reference,and anterior tibial tendon as a distal marker.The mechanical axis of lower ex-tremity in full-length X-ray was measured before surgery,and the tibial prosthetic coronal alignment was checked two weeks postoperation,evaluating the accuracy of this extramedullary cutting system guided by our method.Results:Since good alignment was defined as an angle within 3 degrees of the perpendicular to the mechanical axis,the tibial component positions were acceptable in 191 knees (90.1%),five knees were in valgus postoperative,and sixteen knees were in varus.There were seventeen(8.7%)in 179 knees with a preoperative varus presented malalignment after surgery,and four in 12 preoperative valgus kneess howed malalignment also,no statistical difference was found by Chi-square test (χ2 =2.778,P=0.096),which cannot define the relationship between the varus or valgus deformity preopera-tion and the malalignmentposition in tibial prosthesis after surgery.Twenty-two knees suffered a severe preoperative deformity as a varus or valgus angle larger than 20 degrees with absolute value of mechanical axis before surgery and tibial prosthetic coronal alignment were 21.95°(20.00°,26.90°)and 1.85° (0.10°,7.10°),showed a significant difference (Z =2.11,P =0.035 )compared with the data [10.65°(0.50°,19.80°)in preoperative mechanical axis and 1.10°(0.00°,4.60°)in the tibial pros-thetic coronal alignment]of 190 knees who presented a mild deformity before surgery(less than 20 de-grees),the result indicated the severe preoperative deformity might be a potential mal-alignment risk fac-tor within this cutting system in TKA surgery.Conclusion:The tibial coronal alignment after total knee arthroplasty could achieve good results with extramedullary cutting guide,by using one third inner-medial tibial tubercle and anterior tibial tendon as a proximal and distal anatomy marker.Postoperative varus might occur in this system,and tibial prosthetic malalignment appeared more often in the patients who suffered a severe deformity before surgery.

Objective To explore the potential role of brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide(NT-proBNP) in the assessment of patients with connective tissuediseases(CTD) associated pulmonary arterial hypertension (PAH). Methods Thirty patients with CTD associated PAH were evaluated by WHO function, echocardiography, right heart catheterization and blood biomarkers. All the clinical data was analyzed statistically. Results All patients [age (39.5 ± 11.6) yr]were female. Both NT-proBNP and BNP were significantly increased and significantly correlated ( all P ＜0. 05 ) respectively with mean pulmonary arterial pressure ( r = 0. 53 and r = 0. 40 ), right arterial pressure ( r = 0. 55 and r = 0. 42 ), pulmonary vascular resistance ( r = 0. 69 and r = 0. 61 ), cardiac index ( r = - 0. 58and r = - 0. 46), mixed venous blood oxygen saturation ( r = - 0. 62 and r = - 0. 54 ), pericardial effusion ( r = 0. 46 and r = 0. 43 ), right atrial sizes ( r = 0. 40 and 0. 53, and r = 0. 39 and 0. 45 ) and right ventricular size ( r = 0. 55 and r = 0. 37 ). Furthmore, NT-proBNP, but not BNP, significantly correlated with WHO function class ( r = 0. 55 ). Conclusion Blood NT-proBNP and BNP were elevated in patients with CTD associated PAH and paralleled the extent of function class, pulmonary hemodynamic changes and right ventricular remodeling.

Objective To explore the mechanism of Niaochangshu capsule in the treatment of postmenopausal overactive bladder, through observing its influence on bladder weight and the expression of eNOS and AQP1 of ovariectomized female rats. Methods Female SD rats were divided into blank group, model group, Nilestriol group and Niaochangshu group. Rats were removed ovaries except the blank group. The treatment groups were given corresponding drugs, blank group and model group were given normal saline by gavage. After 4 weeks, the bladders' weight and thickness were detected, the expressions of eNOS and AQP1 in serum and bladder tissue were determined by ELISA, and NO by spectrophotometry. Results Ovariectomy resulted in decreased bladder weight, bladder mucosal and muscular atrophy, and opposite changes showed after given Niaochangshu. The expressions of eNOS and NO in bladder and serum were decreased significantly after ovariectomy, while increased by given Niaochangshu capsule or nylestriol (P<0.05), and there was significant difference between Niaochangshu group and Nilestriol group (P<0.05). The expression of AQP1 was decreased in the model group, and increased after given nylestriol or Niaochangshu capsule. While the expression of AQP1 in bladder had no significant difference among the four groups. Conclusion Niaochangshu capsule can reverse bladder mucosal and muscular atrophy caused by estrogen deficiency, and increase the content of eNOS in serum and bladder, thus play the role in the treatment of postmenopausal overactive bladder.
