Objective To investigate the application value of human papillomavirus (HPV) combined with thinprep cytology test (TCT) detection in screening of cervical cancer. Methods 276 patients were enrolled to have HPV and TCT tests at Department of Gynecology, Shanxi Cancer Hospital from January to December in 2014. Pathological examine was applied to the patients with abnormal results of HPV and TCT. The diagnostic value of HPV, TCT and their combinations was evaluated by the diagnostic sensitivity and the rate of coincidence with the pathological examine results. Results The sensitivity of HPV and its coincidence with the pathological examine results were 81.52 % (225/276) and 79.56 % (179/225), respectively, while those of TCT were 87.68%(242/276) and 76.86%(186/242), respectively. The coincidence rate between the combination method and the pathological examination was higher (94.71%, 197/208) than the individual test. Conclusion HPV combined with TCT detection can reduce the misdiagnosis rate and improve the diagnostic accuracy rate, indicating that this method is of great value in the cervical cancer screening.

Objective To observe the effect of Wenxiao Granule on the expression of MCP-1 and TNF-? in experimental atherosclerosis rabbit, and explore its mechanism in treating atherosclerosis. Methods Thirty-six New Zealand rabbits were randomized to four groups: control group, Wenxiao granule group, Simvastatin group. They were fed a high-fat diet except normal group until the mature atherosclerotic plaques formed. The rabbits in two drug-treated groups were treated with respective drug for 8 weeks. All rabbits were sacrificed. The morphology and composition of atherosclerotic plaques in aortic roots were examined. The expression of MCP-1 and TNF-? were determined by immunohistochemical staining. Results The expression of MCP-1 and TNF-? in plaque of Wenxiao Granule group and simvastatin group were significantly dereased compared with the model group (P 0.05). Conclusion Wenxiao Granule can inhibit the expression of MCP-1 and TNF-?, which may stabilize plaque of atherosclerosis.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

Objective To explore the effect of recombinant pEGFP-N3-APC vectors carrying various APC functional domains on the expression of β-catenin in human colorectal cancer cells HT-29.Methods The recombinant plasmids were transfected into HT-29 cells mediated by lipofectamine~(TM) 2000, and detected by green fluorescence and RT-PCR. Western blot was applied to detect β-catenin expression level in HT-29 cells after transfection, and gray scales of electrophoresis strips were analyzed by SPSS 13.0.Results Green fluorescence and RT-PCR made clear that all 5 recombinant plasmids were successfully expressed in HT-29 cells. Western blot showed that β-catenin expression level in HT-29 cells was not affected after being transfected with pEGFP-N3-APC1, pEGFP-N3-APC2 and pEGFP-N3-APC3, and was distinctly affected after being transfected with pEGFP-N3-APC4 and pEGFP-N3-APC5, especially the later one. Conclusion The selected APC5 gene fragment with 15-amino acid repeats and SAMP repeats, which is relatively short, can degrade β-catenin level in HT-29 cells and may be applied in the gene therapy.

A novel method for DNA detection was developed based on the excellent fluorescence properties of cationic conjugated polymer ( CCP)and the target DNA enrichment,separation function of nanoparticles. First,the quencher-labeled DNA capture probes were modified on the surface of Au nanoparticles,and complementary DNA strands were captured. Second,S1 nuclease was added,and the capture probes that had not captured the complementary DNA were removed from the nanoparticles.Finally,the complementary double-stranded DNA was cut by Dnase I,the quenchers were dissociated from nanoparticle and the fluorescence of CCP was quenched by means of combination of quenchers and CCP.The results showed that this method is specific.In the range of 5. 0 -40 nmol/L,the concentration of target DNA was proportional to the fluorescence quenching and the detection limit was 3.7 nmol/L(S/N = 3).

Objective To assess the effects of Guanxinshutong capsule(GXST)on protection of left ventricular(LV)function after acute myocardial infarction(AMI)in rats.Methods Twenty-eight male Sprague Dawley rats were randomized to Model group,Drug group and Sham-operated group,with acute myocardial infarction(AMI)achieved by ligating coronary artery in Model and Drug groups.From one week before surgery to four weeks after surgery,GXST for Drug group(1.5 g/kg,2 times/day)or saline for Model and Sham-operated groups was administered via direct gastric gavage.After four weeks of treatment following surgery,measurement of LV function,pathohistological observation and analysis were performed.Results Compared with rats in the Model group,LV systolic pressure(LVSP)[(97.7 ± 9.0)mm Hg (1 mm Hg =0.133 kPa)vs(85.9 ±9.4)mm Hg],the maximum rising rate of LV pressure(+ dp/dtmax)[(4810.2 ± 595.0)mm Hg/s vs(3786.2 ± 723.0)mm Hg/s]and the maximum dropping rate of LV pressure(-dp/dtmax)[(3781.6 ±573.6)mm Hg/s vs(2774.4 ±633.5)mm Hg/s]in the Drug group were significantly increased,while LV end-diastolic pressure(LVEDP)[(10.3 ± 0.7)mm Hg vs(12.7 ±2.4)mm Hg]in the Drug group was significantly decreased(all P ＜ 0.05).Myocardial pathohistological morphology was improved in the Drug group with fibrosis alleviated[(5.13 ± 1.37)％ vs(7.27 ±1.01)％]and infarct size reduced[(20.14 ± 8.49)％ vs(31.90 ± 4.98)％].Apoptosis index(AI)was decreased[(14.05 ± 4.04)％ vs(20.87 ± 6.03)％]and vessel density was significantly increased by 1.48-fold in the Drug group(all P ＜ 0.05).Conclusions GXST is effective in protecting LV function after AMI in rats,which may be affect through increasing vessel density of infarction area,improving myocardial pathohistological morphology,alleviating fibrosis,reducing infarct size and decreasing AI.

BACKGROUND: How to effectively treat recurrent osteoporotic vertebral compression fractures in the elderly over 65 years has become an issue of attention in the clinic. OBJECTIVE:To evaluate the clinical efficacy of percutaneous vertebroplasty with polymethylmethacrylate bone cement for treating elderly recurrent osteoporotic vertebral compression fractures. METHODS:Twenty-four patients with elderly osteoporotic vertebral compression fractures were divided into polymethylmethacrylate bone cement group (minimaly invasive group) and conservative treatment group on a voluntary basis (n=12 per group). Visual analog scale score for low back pain, Oswesty dysfunction index, ratio of the anterior/posterior margin height of the injured vertebra, Cobb angle and adverse reactions were compared between the two groups before and after treatment. RESULTS AND CONCLUSION:The 12-month folow-up was completed in al the patients. There was one case of bone cement breakage during treatment in the minimaly invasive group and one case of lower limb deep venous thrombosis in the conservative treatment group at 1 month after treatment. Compared with the conservative treatment group, the visual analog scale score, Oswesty dysfunction index, and Cobb angle were significantly lower, but the ratio of the anterior/posterior margin height of the injured vertebra was significantly higher in the minimaly invasive group at 3 days, 1, 3, 6 and 12 months after treatment (P < 0.05). These findings indicate that percutaneous vertebroplasty with polymethylmethacrylate bone cement for elderly recurrent osteoporotic vertebral fractures can strive for short-term pain relief and long-term recovery of the vertebral height and spinal Cobb angle, thereby significantly improving patient’s quality of life.

Background The protective effects against reperfusion injury of cardioprotective drugs have recently been evaluated and found to be inadequate. Guanxinshutong (GXST), a combination of the traditional herb and Mongolian medicine, is effective and safe in treating angina pectoris in clinical trials. We assess the cardioprotective effects of GXST against myocardial ischemia and reperfusion (MI/R) injury in rats and explore its possible mechanism. Methods Forty-five male Sprague Dawley rats were randomized into three groups: non-MI/R group (Sham, n = 15), MI/R group treated with vehicle (Control, n = 15) and MI/R group treated with GXST (Drug, n = 15). MI/R was induced by ligation of the left anterior descending coronary artery (LAD) for 30 minutes, followed by 2/24 hour reperfusion in the Control and Drug groups. In the Sham group, the LAD was exposed without occlusion. GXST powder (in the Drug group) or saline (in the Control and Sham groups) were administered via direct gastric gavage from 7 day prior to surgery. Blood samples were collected from the carotid artery (10 rats each group) after 2 hours of reperfusion, to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) using enzyme-linked immunosorbent assays. The animals were then sacrificed and the hearts were harvested for histopathology and western blot analysis. Infarct size was measured in the remaining five rats in each group after 24 hours reperfusion. Results GXST significantly decreased levels of TNF-α, IL-1β, IL-6, ICAM-1, apoptosis index (AI) and infarct size. GXST also obviously inhibited nuclear factor kappa B (NF-κB) activity when compared with the Control group (all P < 0.05). Conclusions GXST is effective in protecting the myocardium against MI/R injury in rats. Its possible cardioprotective mechanism involves inhibition of the inflammatory response and apoptosis following MI/R injury.

OBJECTIVE:To investigate the effects of Melilotus extract tablet on postoperative therapeutic efficacy of chronic sinusitis endoscopic surgery and the recovery of nasal mucosa. METHODS:The clinical data of 100 patients undergoing chronic si-nusitis functional endoscopic surgery in our hospital from May 2015 to Oct. 2016 were analyzed retrospectively and they were divid-ed into control group and observation group according to postoperative treatment,with 50 cases in each group. Two groups received anti-inflammatory,anti-histamine and hemostasis therapy. The control group received Eucalyptol,linonene and pinene enteric soft capsules 0.3 g,tid;observation group was additionally given Melilotus extract tablet 1.2 g,tid,for 6 weeks,on the basis of con-trol group. VAS and Lund-Kennedy endoscopic score were compared between 2 groups before and after treatment. Clinical effica-cies and the occurrence of ADR were also compared between 2 groups. RESULTS:there was no statistical significance in VAS score and its total score,Lund-Kennedy endoscopic score and its total score between 2 groups before treatment (P>0.05). After treatment,VAS score and its total score,Lund-Kennedy endoscopic score and its total score of 2 groups were significantly de-creased,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The cure rate of observation group was 72.0%,which was significantly higher than 44.0% of control group,with statistical significance (P<0.05). There was no significant difference in the incidence of adverse reactions between the 2 groups (P>0.05). CONCLU-SIONS:Melilotus extract tablet helps to improve clinical efficacy and the recovery of nasal mucosa in patients with chronic sinus-itis after endoscopic surgery,with good safety.
