Objectives To investigate the clinical feature of Parkinson's disease (PD) with restless leg syndrome (RLS) and the pathogenesis of RLS. Methods We conducted a cross-sectional and control study. The case group concluded 31 PD with RLS patients, meanwhile 39 PD patients were selected as the control group. Clinical history, clinical manifestations, complications and laboratory examinations were compared respectively between the two groups. Results All the RLS symptoms did not appear in RLS patients until the PD symptoms came out. Significant differences were found in complications such as swallow disturbance, constipation and illusion, when we compared the two PD groups (P ＜ 0.05 ). Compared with the PD or healthy group, the level of serum ferritin and the H-reflex latency of tibial nerve were significantly decreased in PD with RLS group ( P＜0.05). Conclusions Secondary RLS is a complication of PD.Deficiency of iron and decreased inhibition function of spinal cord may lead to the occurrence of RLS in PD patients. When their motor symptoms are serious and complications are more common, PD patients are more possible to have RLS symptoms.

Objectives To explore the significance of measuring free/total(f/t) prostate-specification antigen (PSA) ratio, testosterone (T) and free testosterone (FT) in the patients with prostate cancer for performing biopsy with PSA values between 2 and 4 ng/ml.Methods The f/tPSA ratio and total and free testosterone levels in two hundred and seventy-five men with serum PSA values between 2 to 4 ng/ml were quantified.Serum free testosterone levels were measured by immuno-radiometric assay (IRMA), f/tPSA and testostorone levels were determined by chemiluminescence immunoassay (CLIA), underwent transrected ultrasound-guided biopsy (TRUS) was used as the diagnostic standard to detect the earlier prostate cancer in these patients. The diagnostic sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and confidence interval of 95% were determined by receiver operating characteristic (ROC) curve.Results Prostate cancer was detected in 44 of 275 patients(16%). f/tPSA ratio and total and free testosterone levels in the patients with prostate cancer were significantly lower than those in nonprostatic cancer groups (P

Objective To explore the protective effcets of Schisandra chinensis extract (SCE) in paraquat (PQ)-induced pulmonary fibrosis in mice ,and its intrinsic molecular mechanisms thereof. Methods A total of 108 mice were randomly allocated into six groups (n=18):control group, model group, low concentration of SCE group (200 mg/kg), medium concentration of SCE group (400 mg/kg), high concentration of SCE group (800 mg/kg) and vitamin C group (100 mg/kg). Except control group, mice were given by intragastric administration with PQ (100 mg/kg) and administered with SCE and Vitamin C once per 24 h after PQ modeling. Mice were sacrificed at 7, 14 and 21 d after modeling. Six mice were executed at different time points. The degree of lung tissue inflammation and fibrosis were observed by HE staining and Masson staining. The mRNA and protein expression levels of transforming growth (TGF)-β1, interleukin (IL)-6 and IL-17 in lung tissue were determined by RT-PCR and ELISA respectively. Results (1) Compared with control group, the lung tissue of model group showed a large number of inflammatory cell infiltration, space congestion, and its inflammation scores increased at 7 and 14 days after modeling (P<0.05). At the same time, compared with model group and vitamin C group, inflammation scores were significantly decreased in medium concentration of SCE group and high concentration of SCE group (P<0.05). (2) Compared with control group, collagen fibers and the degree of fibrosis were significantly increased in model group ,while pulmonary fibrosis were decreased in medium concentration of SCE group and high concentration of SCE group at 14 and 21 days after modeling (P<0.05). (3) With the extension of modeling time, both mRNA and protein expressions of TGF-β1 were obviously elevated, IL-6 decreased and IL-17 reduced after the first increase in PQ group. Compared with PQ group, levels of three cytokines mRNA and protein expression in medium concentration of SCE group and high concentration of SCE group changed as follows:IL-6 level was markedly decreased at 7 and 14 days after modeling;TGF-β1 level was markedly increased at 14 and 21 days after modeling. However, IL-17 level was markedly decrease at three time points(P<0.05). Conclusion SCE can relieve PQ-induced lung inflammation and fibrosis by suppressing TGF-β1, IL-6, and IL-17 expressions.

BACKGROUND/AIMS: This study was designed to investigate the effect of Fengliao-Changweikang (FLCWK) in diarrhea-predominant irritable bowel syndrome (IBS-D) rats and explore its underlying mechanisms. METHODS: IBS-D model rats were induced by neonatal maternal separation (NMS) combined with restraint stress (RS). In in vivo experiments, the model rats were randomly divided into 5 groups: NMS + RS, FLCWK (low dose, middle dose, and high dose), and pinaverium bromide. The normal control (no handling) rats were classified as the NH group. The therapeutic effect of FLCWK was evaluated by fecal characteristics, electromyographic response and abdominal withdrawal reflex scores. In in vitro experiments, the model rats were randomly divided into 2 groups: NMS + RS, FLCWK (middle dose), and no handling rats were used as the NH group. The differences in basic tension and ACh-induced tension of isolated colonic longitudinal smooth muscle strips (CLSMs) among the 3 groups were observed. In addition, different inhibitors (nifedipine, TMB-8, L-NAME, methylene blue, and 4-AP) were pretreated to explore the underlying mechanisms. RESULTS: In in vivo experiments, fecal characteristics, electromyographic response, and abdominal withdrawal reflex scores significantly improved in the FLCWK group, compared with the NMS + RS group. In in vitro experiments, the basic tension and ACh-induced tension of CLSMs in IBS-D rats were significantly inhibited by FLCWK. After pre-treatment with different inhibitors, the ACh-induced tension of CLSMs in each group showed no significant difference. CONCLUSIONS: FLCWK manifested curative effect in IBS-D rats by inhibiting colonic contraction. The underlying mechanisms may be related to regulatory pathway of nitric oxide/cGMP/Ca2+ and specific potassium channels.

Objective: To investigate the effect and safety of intensive hyperthermia combined with low-dose cisplatin plus radiotherapy in the treatment of patients with locally advanced NSCLC. Methods: From January 2012 to December 2015, 104 patients with locally advanced NSCLC were chosen in the Second People's Hospital of Weifang and randomly divided into two groups according to the digital table, with 52 patients in each group.The control group was given low-dose cisplatin plus radiotherapy, and the observation group was given intensive hyperthermia on the basis of control group.The ORR, DCR, median OS, median PFS, KPS score, the levels of coagulation function index and tumor markers before and after treatment and incidence of side effects in the two groups were compared. Results: The DCR of the observation group was significantly higher than that of the control group(86.54% vs.69.23%, χ²=8.24, P<0.05). The median OS and median PFS of the observation group were significantly longer than those of the control group(11.9 months vs.8.3 months; 7.5 months vs.4.7 months, t=2.56, 3.01, P<0.05). The KPS scores after treatment of the observation group were significantly higher than those of the control group and before treatment[(75.49±8.94)points vs.(68.65±7.06)points; (75.49±8.94)points vs.(62.23±6.34)points, t=2.78, 5.11, all P<0.05]. The levels of coagulation function index and tumor markers after treatment of the observation group were significantly lower than those of the control group and before treatment(t=3.14, 2.67, 3.59, 7.31; 4.89, 4.02, 4.70, 9.21; 2.44, 2.60, 3.20; 3.15, 3.78, 4.06; all P<0.05). There was no statistically significant difference in the incidence of side effects between the two groups(P>0.05). Conclusion Intensive hyperthermia combined with low-dose cisplatin plus radiotherapy in the treatment of patients with locally advanced NSCLC can efficiently control disease progress, increase survival benefits, higher quality of life, improve coagulation function, reduce the levels of tumor markers and possess satisfactory safety.

Objective To investigate the effect of acidic tumor microenvironment on invasion and migration and its mechanism in glioma cells. Methods (1) The pH value of the medium was adjusted by acid-base titration. Human glioma cells U87 and U251 were cultured in the acid group and the normal group with pH values of 6.4 and 7.4, respectively; and 3 d after cultivation, the expressions of hypoxia-inducible factor-2α (HIF-2α) and CD44 were detected by Western blotting; Transwell assay was used to examine the invasion and migration of U87 and U251 cells; immunofluorescence was employed to examine the CD44 expression. (2) The U87 and U251 cells were divided into small interfering RNA (siRNA) -nonsense sequence group and siRNA-CD44-1 group, and the siRNA nonsense sequences and siRNA-CD44-1 interfering fragments were transfected by lipofectin-3000, respectively; three d after transfection, the migration and invasion abilities of cells from the two groups were detected by Transwell assay. (3) U87 and U251 cells were divided into acid group (cultured with a pH value of 6.4), blank control group, siRNA nonsense sequence group, siRNA-CD44-1 group, and siRNA-CD44-2 group; and cells from the later four groups were cultured with a pH value of 7.4; after culture for 4 d, the siRNA-nonsense sequence group, siRNA-CD44-1 group and siRNA-CD44-2 group were transfected with siRNA-nonsense sequences, siRNA-cd44-1 interfering fragments and siRNA-CD44-2 interfering fragments, respectively; three d after transfection, the expressions of CD44, N-Ca, Vimentin, and matrix metalloproteinase (MMP)-2 proteins in these 5 groups were detected by Western blotting. Results (1) As compared with the normal group, the expression levels of HIF-2α and CD44 in U87 and U251 cells of the acid group were significantly increased; both Transwell and invasion experiments showed that the number of transmembrane cells in the acid group was significantly larger than that in the normal group (P<0.05); immunofluorescence staining showed that the CD44 expression in acid group was significantly higher than that in normal group (P<0.05). (2) Both Transwell and invasion experiments showed that the number of transmembrane cells in the siRNA-CD44-1 group was significantly smaller than that in the siRNA nonsense sequence group (P<0.05). (3) Western blotting showed that the expression levels of CD44, N-Ca, Vimentin and MMP-2 in U87 and U251 cells of the blank control group, siRNA nonsense sequence group, siRNA-CD44-1 group, and siRNA-CD44-2 group were obviously decreased as compared with those in the acid group; the expression levels of CD44, N-Ca, Vimentin and MMP-2 in U87 and U251 cells of the siRNA-CD44-1 group and siRNA-CD44-2 group were obviously lower than those in the siRNA nonsense sequence group. Conclusion Acidic tumor microenvironment enhances the capabilities of invasion and migration of glioma cells through increasing CD44 expression.
