Objective To analyze the clinical effects of small needle -knife therapy with movement exercise on knee osteoarthritis (KOA).Methods The clinical data collected from all the patients with hospital care and other 60 patients with KOA treated in the outpatient department in People's Hospital of Changzhi from February 201 4 to August 201 4.The patients were divided into needle -knife group and hyaluronan group,30cases in each group.The needle -knife group was given small needle -knife therapy to each patient one or two times.The hyaluronan group was given weekly intra -articular hyaluronan treatment,once a week,5times in total.But all the patients must do the same exercise movement as treatment.The clinical efficacy evaluation went on 6 months to follow up the patients.The evaluation for each patient was made at 0.5,1 st,2nd,4th,and 6th months using the following measures:WOMAC (Western Ontario and McMaster University Osteoarthritis Index)global assessment and SF -36 (short form 36). Make a contrast to the efficacy of both therapies on the osteoarthritis of knee joint from pain -easing and functional recovery.And the results were synthetically analyzed.Results In terms of pain assessment,the outcomes obtained by WOMAC on the two groups was statistically effective in the phase of 1 -6 months (t =-5.952,P <0.001 ),while those by SF -36 showed differences between the first 0.5 month and 6th month (t =3.1 21 ,P <0.001 ,t =4.091 , P =0.01 1 ).In terms of the functional assessment,the figures obtained by the WOMAC manifested that the needle -knife group was significantly superior to the hyaluronan group at the second and sixth months (t =-8.579,P <0.001 ,t =-3.993,P =0.003),and SF -36 also displayed that after treatment,the objects from the two groups per-formed distinctively in the first half,first,and sixth month respectively.(t =6.1 32,P <0.001 ,t =5.063,P =0.0068, t =8.1 09,P =0.003).Conclusion Small needle knife with movement exercise can obviously improve activity -related function of knee joint and relief the pain for the patients with KOA.

Objective To explore the relationship between the level of tumor necrosis factor related apoptosis inducing ligand(TRAIL) and death receptor 5(DR5) and atherosclerosis(AS).Methods Eighty-three patients were divided into two groups: Sixty-one in the coronary artery disease(CAD) group and 22 in normal coronary artery group.Plasma soluble TRAIL(sTRAIL) and soluble DR5(sDR5) levels from these people were assayed by ELISA.The level of TRAIL and DR5 protein expression in coronary arteries were detected by immunohistochemisty statining.Results Plasma sTRAIL and sDR5 significantly increased in the CAD group(P

In recent years, lower and lower class attendance has plagued the quality of uni-versity teaching. To solve this problem, this study conducted a questionnaire survey in accordance with the concepts of the Education Reform microscopic systems engineering and the method of SIMPP. The results showed that factors affecting student classroom attendance included two aspects: the sub-jective and objective factors. Indicators related to the subjective factors were: the personal attitude when faced with failure exams, the personal learning interest and personal grasp of the main source of knowledge. Indicators related to the objective factors were: school and teachers. Also, this study gave some suggestions on how to improve students' classroom attendance to provide data basis and refer-ence for further study on class attendance.

College students' self cognition of the learning effectiveness influences their learning behavior greatly. Focusing on college students' self cognition of their learning effectiveness, and then standardizing their learning behavior is one of the important work of educators in colleges. Therefore this paper has designed the questionnaire of the influencing factors of learning effectiveness self cog-nition, used SIMPP analysis method to analyze it, and set up the relation model. The analysis shows that college students' self cognition of learning effectiveness is influenced not only by students' dili-gence level and the recognition degree of specialized subject, but also by the factors such as the attitude when you get the bad results. The result provides data basis and scientific basis for future practice and relevant research for educators in colleges.

In this study, microcalorimetry was adopted to establish a novel method for detecting the hemagglutination process of Radix Isatidis (Banlangen in Chinese, BLG), and to evaluate the hemagglutination activity diversity of BLG from various habitats. The hemagglutination biothermokinetics curves of positive reagent (phytohemagglutinin, PHA) and 8 batches BLG from different regions of the hemagglutination with 20% rabbit erythrocyte were recorded by microcalorimetry, then biothermokinetics parameters were abstracted, the hemagglutination utility of samples were calculated and analyzed by principal component analysis (PCA) and cluster analysis (CA), meanwhile the results were authenticated by micro-plate agglutination. It showed that the hemagglutination was an exothermic reaction, the reaction rate constant (k: 0.039-73.6 min(-1)), maximum reaction power (Pmax: -1 140.2 - 988.2 microW) and reaction enthalpy (Hi: -529.9 - 717.9 microJ) had good linear correlation with BLG extraction concentration (0.2-1.0 g mL(-1), r > 0.97), and PCA showed Pmax (531-1 335 microW) and Ht (585.2-989.2 microJ) could represent the hemagglutination activity diversity of BLG samples, just confirming with the results of micro-plate agglutination (the agglutination dilution was 3-11 respectively). According to the hemagglutination utility, the BLG samples from Good Agriculture Practice (GAP) regions, main producing area and general regions could be clustered correctly; meanwhile, the biothermokinetics curves with perfect distinctive fingerprint and specificity could give out more information for the quality control and evaluation for BLG. In conclusion, the microcalorimetry method established for detecting the hemagglutination activity of BLG samples on rabbit erythrocyte is sensitive and reliable, and could be adopted as an effective technique in detection aggulatination precisely, quantitatively and consecutively; and provide a novel approach for examining and evaluating quality for Chinese herbal medicine with aggulatinative activity such as BLG.

The five-flavor theory of traditional Chinese medicines (TCM) and the flavor efficacy generation mechanism has long been focuses and difficulties in studies on traditional Chinese medicinal properties. In this paper, by using the pharmacophore-based virtual screening technique, the authors discussed the relations between the pungent property and transient receptor potential vanilloid 1 (TRPV1) by studying the TCM components' role in regulating TRPV1 ion channel. The results showed that the matching relationship between TRPV1 agonist pharmacophore model and TCM chemical components could identify the active ingredients from pungent herbs. Therefore, the authors proposed that TRPV1 is one of the potential targets for efficient pungent herbs. The pungent property of TCMs is decided by its chemical components, and consistent with the inherited and additive characteristics.

OBJECTIVETo observe the characteristics of sperm single-stranded DNA breaks (SSB) and double-stranded DNA breaks (DSB) in infertile men, explore the association of DSB with male infertility, and provide a new observation index and idea for the diagnosis and treatment of the disease.

METHODSThis study involved 60 infertile men (infertility group) and 30 normal healthy males with infertile wives (control group). We comparatively analyzed the seminal parameters of the two groups, determined sperm concentration and viability using the computer aided sperm analysis system, measured the sperm survival rate by hypoosmotic swelling (HOS) test, examined sperm morphology by Diff-Quick staining, and detected sperm DNA damage by two-tail comet assay.

RESULTSNine two-tail comet models were established for detecting sperm DNA integrity. Comparisons between the fertility and control groups showed that the sperm DNA fragmentation index (DFI) was (33.8 ± 13.1) vs (16.3 ± 7.9)% (P < 0.01), the SSB-DFI was (19.2 ± 11.4) vs (14.9 ± 7.6)% (P > 0.05), the SSB-DFI/DFI was (56.8 ± 32.4) vs (91.4 ± 27.8)% (P < 0.01), the DSB-DFI was (23.9 +13.4) vs (6.1 ± 2.7)% (P < 0.01), and the DSB-DFI/DFI was (70.8 ± 19.5) vs (37.4 ± 11.3)% (P < 0.01). The optimal cut-off value of DSB-DFI/DFI in the diagnosis of male infertility was 39.5%, with the AUG, sensitivity, and specificity of 0.969, 98.3%, and 90%; that of DSB-DFI was 15.85%, with the AUC, sensitivity, and specificity of 0.912, 86.7%, and 80%; and that of DFI was 18.65%; with the AUC, sensitivity, and specificity of 0.861, 90%, 70%, respectively. In the infertile men, neither SSB-DFI nor SSB-DFI/DFI exhibited any correlation with semen parameters (P > 0.05); DFI was correlated negatively with the percentage of progressively motile sperm, sperm survival rate, and the percentage of morphologically normal sperm (P < 0.05 or P < 0.01), but not correlated with sperm concentration (P > 0.05); both DSB-DFI and DSB-DFI/DFI showed a negative correlation with sperm concentration, sperm survival rate, and the percentages of progressively motile sperm and morphologically normal sperm (P < 0.05 or P < 0.01).

CONCLUSIONDouble-stranded, rather than single-stranded DNA breaks, may be a factor inducing male infertility. The type of sperm DNA strand damage is of much reference value for the assessment of male fertility.

Objective To investigate the effects of glycogen synthase kinase-3β (GSK-3β) and β-catenin signaling on the human renal proximal tubular epithelial HK-2 cell injury induced by depleted uranium(DU),and provide a new enlightenment for the development of DU antidotes.Methods H K-2 cells were exposed to different concentrations of DU for 3-24 h,then the protein expressions of kidney injury molecule 1 (KIM-1),neutrophil gelatinase-associated lipocalin (NGAL) and nuclear β-catenin were detected by immunofluorescence staining.The protein expressions of p-GSK-3 β(S9),GSK-3β and cmyc were detected by Western blot assay.HK-2 cells were transiently transfected by GSK-3β (KD) plasmid or treated by TDZD-8 to inhibit the activity of GSK-3β specifically.Other HK-2 cells were transiently transfected by β-catenin plasmid to overexpress the β-catenin protein.Results The percentages of KIM-1 and NGAL-positive cells increased with DU exposure time and concentrations from 300 and 600 μmol/L,and they were significantly higher than those of the blank control at 6-24 h of DU exposure (KIM-1-positive cells:t =11.06,18.97,30.49,P ＜0.05;t =6.79,16.02,85.45,P ＜ 0.05;NGAL-positive cells:t =11.78,11.37,34.29,P ＜0.05;t =7.34,21.63,36.84,P ＜0.05).In contrast,the ratio of p-GSK-3β (S9) to GSK-3β and percentage of nuclear β-catenin-positive cells were significantly higher than that of the blank control at 3-24 h of DU exposure (p-GSK-3β(S9)/GSK-3β:t =3.95,4.69,5.40,3.34,P ＜ 0.05;nuclear β-catenin-positive cells:t =4.61,6.52,36.64,14.93,P ＜ 0.05) with a maximum response at 9 h of DU exposure accompanied with corresponding increase of protein level of c-myc,a downstream target gene of β-catenin.Transient transfection of HK-2 cells with GSK-3β (KD) plasmid significantly inhibited the activity of GSK-3β (t =8.07,P ＜ 0.05) and reduced the DU-increased percentage of KIM-1-positive cells (t =24.77,P ＜ 0.05).Treatment cells with TDZD-8 inhibited the activity of GSK-3β and enhanced the percentage of nuclear β-catenin-positive cells,and it also significantly reduced the percentage of KIM-1-positive cells in HK-2 cells exposed to DU (t =6.25,6.73,P ＜ 0.05).Moreover,overexpression of β-catenin significantly reduced DU-induced cell injury (t =7.48,P ＜ 0.05).Conclusions GSK-3β/β-catenin signaling plays a key role in regulating the DU-induced cytotoxicity of HK-2 cells.Inhibition of GSK-3β activity and overexpression of β-catenin can protect the HK-2 cells from DU-induced damage.
