CCL2 promotes angiogenesis of primary rat cardiac microvascular endothelial cells / 生理学报

The aim of the present study was to investigate the role of chemokine CCL2 in angiogenesis of primary adult rat cardiac microvascular endothelial cells (CMEC). The rat CMECs were isolated and identified through morphology examination and immunostaining with CD31 and factor VIII antibodies. The angiogenesis of CMEC on Matrigel was evaluated at different time points. The expression and secretion of CCL2 during the process of angiogenesis was detected by real-time RT-PCR and ELISA, respectively. The results showed that, the primary rat CMEC was isolated successfully, and the angiogenesis of CMEC was significantly induced after Matrigel treatment for 4 h. The expression of CCL2 and CCR2 were increased during angiogenesis, and the secretion of CCL2 was detected after 2 h of angiogenesis and reached the peak concentration of 1 588.1 pg/mL after 4 h. Either CCL2 blocking antibody or CCR2 antagonist significantly reduced the angiogenesis of CMEC. These results suggest that CCL2 is secreted during the process of angiogenesis of CMEC, and CCL2/CCR2 signaling pathway may play an important role in promoting angiogenesis.

Advance in Rehabilitation for Vestibular Dysfunction after Mild Traumatic Brain Injury (review) / 中国康复理论与实践

Mild traumatic brain injury (mTBI) can result in vestibular dysfunctions, such as dizziness, vertigo and imbalance. Vestibular rehabilitation is effective on vestibular dysfunction after mTBI. This paper reviewed the possible mechanisms of vestibular dysfunction caused by mTBI, the common assessments of vestibular function and the new progress in vestibular rehabilitation.

The regulation of retinoid X receptor-mediated oxidative stress pathway in rat pulmonary ischemia/reperfusion injury / 生理学报

The aim of this study was to investigate the regulatory role of retinoid X receptor (RXR)-mediated oxidative stress pathway in rat pulmonary ischemia/reperfusion injury (PIRI) and the underlying mechanism. Seventy-seven male Sprague-Dawley (SD) rats were randomly divided into 7 groups (n = 11): control group, sham group, sham+9-cis-retinoid acid (9-cRA, RXR agonist) group, sham+HX531 (RXR inhibitor) group, ischemia/reperfusion (I/R) group, I/R+9-cRA group, and I/R+HX531 group. The unilateral lung I/R model was established by obstruction of left lung hilus for 30 min and reperfusion for 180 min in vivo. The rats in I/R+9-cRA and I/R+HX531 groups were given intraperitoneal injection of 9-cRA and HX531 before thoracotomy. After reperfusion, the left lung tissue was taken to evaluate the lung tissue injury, and the oxidative stress-related indexes of the lung tissue were detected by the corresponding kits. The lung tissue morphology and the ultrastructure of the alveolar epithelial cells were observed by HE staining and transmission electron microscope, respectively. The protein expression of RXR in lung tissue was observed by immunofluorescence labeling method, and the expression level of nuclear factor E2-related factor (Nrf2) protein was detected by Western blot. The results showed that, compared with the sham group, the I/R group exhibited obviously injured lung tissue, decreased SOD activity, increased MDA content and MPO activity, and down-regulated expression level of Nrf2 protein. Compared with the I/R group, the I/R+9-cRA group showed alleviated lung tissue injury, increased activity of SOD, decreased MDA content and MPO activity, and up-regulated expression levels of RXR and Nrf2 protein. The above-mentioned improvement effects of 9-cRA were reversed by HX531 treatment. These results suggest that RXR activation can effectively protect the lung tissue against I/R injury, and the mechanism may involve the activation of Nrf2 signaling pathway, the enhancement of antioxidant level and the reduction of oxidative stress response.

To compare the efficacy and safety of Lamivudine (LAM) plus Adefovir dipivoxil (ADV) combination therapy and Entecavir (ETV) monotherapy for chronic hepatitis B patients. 120 patients with chronic hepatitis B managed in a single-centre clinical practice (median 96 weeks) were split into 2 cohorts, one was treated with de-novo combination Lamivudine (100 mg/day) plus Adefovir (10 mg/day) (LAM+ADV), the other with Entecavir (0.5 mg/day) monotherapy. Serum levels of ALT, creatinine, HBsAg, HBeAg and HBV viral load, together with genotypic resistence were analyzed at 0, 12, 24, 48, 96 weeks, respectively. HBV DNA was determined by real-time PCR. HBsAg and HBeAg were assessed by chemiluminescence. Serum levels of ALT and creatinine were detected by automatic biochemical analyzer. HBV genotypic resistence was tested by direct sequencing. (1) At the time point of 96 weeks, a total of 99 patients (51 cases in combination therapy cohort and 48 case in monotherapy cohort) were compared. The baseline characteristics as for HBV viral load, median age, serum levels of ALT and creatinine were compatible between combination therapy cohort and monotherapy cohort. (2) The rates of HBV DNA values is less than 300 copies/ml and HBV DNA values is less than 1000 copies/ml had no significant difference between LAM + ADV and ETV cohorts by the 12 and 24 weeks (P more than 0.05). (3) At the time point of 48 weeks, the rates of HBV DNA is less than 1000 copies/ml, HBeAg seroconversion, and ALT normalization were similar in both cohorts, though the rate of HBV DNA values is less than 300 copies/ml was obviously higher in combination therapy cohort than that of monotherapy cohort (90.7% vs 76%, P values is less than 0.05). (4) At the time point of 96 weeks, the rates of HBV DNA values is less than 300 copies/ml (96.1% vs 79.2%), HBV DNA values is less than 1000 copies/ml (98% vs 87.5%) and the HBeAg seroconversion (41.7% vs 16.7%) were markedly higher in combination therapy cohort than those of monotherapy cohort statistically (P values is less than 0.05 for all). The mean values of decreases for HBV viral loads and HBsAg levels were smilar in both cohorts at 48 and 96 weeks. (5) Elevated serum creatinine not be found in both cohorts at the end of treatment. (6) No virological breakthrough occurred in combination therapy cohort at the end of treatment. Four patients in monotherapy cohort were found with virological breakthrough at 96 weeks and three cases among were confirmed to be of variants associated with ETV resistance (rtL180M + T184L + M204V). Present study suggests that Lamivudine plus Adefovir dipivoxil de-novo combination therapy was more efficacious than Entecavir monotherapy for CHB patients and the tolerance is compatible.
