BACKGROUND:Caffeic acid phenethyl ester (CAPE) can inhibit lipid peroxidation after rat brain injury. However, the trend of 5-lipoxygenaseis (5-LOX) and cysteinyl leukotrienes (CysLTs) in model of Parkinson’s disease, and whether CAPE protects against rotenone-induced cel ular injuries by inhibiting the levels of 5-LOX and CysLTs stil need further research.
OBJECTIVE:To investigate the protective effect of CAPE on the rotenone-induced Parkinson-like injury, and to determine whether 5-LOX involved.
METHODS:(1) PC12 cel s in good-growth were col ected and divided into five groups cultured with different concentrations of rotenone (0, 0.01, 0.1, 1, 10μmol/L). 24 and 48 hours later, changes of cel ular morphology and activity were observed to single out the optimum concentration of rotenone;at 24 hours, the levels of 5-LOX and CysLTs were detected by western blotting and ELISA, respectively. (2) PC12 cel s were pretreated with different concentrations of CAPE (0, 0.01, 0.1, 1, 10 μmol/L) for 30 minutes, and 1 μmol/L rotenone was then added. The other cel s received no intervention as blank control group. Subsequently, the cel activity was detected, and the CysLTs production was detected by ELISA at 24 hours.
RESULTS AND CONCLUSION:(1) Rotenone (0.1-10μmol/L) could induce PC12 cel injury with overt morphological and cel activity changes at 24 hours, especial y the 1 μmol/L rotenone. (2) Rotenone also significantly increased the 5-LOX expression and CysLTs production in a concentration-dependant manner. (3) CAPE (1-10μmo/L) significantly attenuated rotenone-induced CysLTs production and cel viability reduction in a concentration-dependant manner. (4) These results suggest that CAPE protects against PC12 cel injuries in the model rat with Parkinson’s disease induced by rotenone involving 5-Lox.

Purpose: To evaluate the antiemetic effect of azasetron hydrochloride in patients with liver neoplasm after transcatheter arterial chemoembolization. Methods: 62 patients (33 with primary hepatocellular carcinoma and 29 with hepatic metastasis), who underwent transcatheter arterial chemoembolization( TACE) therapy 78 times in all, were allocated into the azasetron group( administration of azasetron hydrochloride) and the control group( administration of metoclopramide) randomly. The inhibitory effects on nausea and vomiting were observed in the two groups respectively. Results: The antiemetic CR ratio and the response rate( CR + PR) in the azasetron group was 81.0% and 99. 7%, respectively. These results were statistically higher than those in the control group( P

Objective:To investigate the satisfaction of the elderly who lived in medical-nursing combined in-stitutions in Weifang and to provide advice to the relevant department for optimizing the medical-nursing combined care mode. Methods:Using the convenience sampling method, 157 subjects from 2 medical-nursing combined institutions in Weifang were selected for the questionnaire survey. Results:The satisfaction score of the elderly was (4. 14 ± 0. 33), which was in the medium to high level. The satisfaction score of each dimension from high to low was listed as the daily life demands, the medical care needs, the recreational demands and psychological demands. Conclusions:The medical-nursing combined pension mode can mostly meet the basic needs of the elderly, but the service content needs to be expanded. It is needed for pension institutions to fully mobilize social resources to a-chieve the sustainable development of medical-nursing combined care mode.

Objective To evaluate the changes of peripheral blood CD4+CD25+ regulatory T cells and its prognostic value in sepsis patients.MethodThe percentage of CD4+CD25+/CD4+ T cells were measured by flow eytometry present in peripheral blood in 36 sepsis patients on day 1,3 and 5 and 15 healthy people (control group).The changes of CD4+CD25+ regulatory T cells were analyzed in survivors group and non-survivors group respectively.Results There were 19 survivors and 17 non-survivors in sepsis patients.The percentage of CD4+CD25+/CD4+ T cells in survivors group and non-survivors group on day 1 was significantly lower than that in eontrol group [(12.42± 3.26)%,(12.96± 3.00)% vs (16.97 ± 3.66)%,P<0.05].The percentage of CD4+CD25+/CD4+ T cells in survivors group and non-survivors group on day 3 were both signifieanfly higher than that on day 1 [(24.47±4.62)%vs (12.42±3.26)%,(26.61±3.85)%vs (12.96±3.00)%,P<0.05].The percentage of CD4+CD25+/CD4+ T cells in survivors group on day 5[(18.28±4.28)%]was significantly lower than that on day 3 (P<0.05),and the percentage of CD4+CD25+/CD4+ T cells in nonsurvivors group on day 5 were significantly higher than that on day 3(P<0.05).There was no significant difference in the percentage of CD4+CD25+/CD4+ T ceils between survivors group and non-survivors group on day 1,3 respeefively(P > 0.05),but the percentage of CD4+CD25+/CD4+ T cells in survivors group was significantly lower than that in non-survivors group on day 5 (P<0.05).Conclusions The CD4+CD25+ regulatory T cells in sepsis patients decreases following by increase after onset.The persistent increase suggests the emergence of immunoparalysis,which is followed by high monaliy,The CD4+CD25+ regulatory T cells are valuable in evaluation of immune state and prediction the prognosis in sepsis patients.

Objective:To discuss the role of incision for short-term outcomes of simultaneous resection in synchronous colorec-tal liver metastases (sCRLM). Methods:We reviewed the data of 37 patients who underwent simultaneous resection between January 2009 and December 2014 in our department and compared the short-term outcomes between Mercedes and midline incisions. Results:Mercedes and midline incisions were used in 19 and 18 patients, respectively. The two groups showed similarities in patient characteris-tics, major hepatectomy, surgery time, blood loss, and hilar block time. The midline group comprised more rectal cancer patients (P<0.001). The two groups did not differ significantly in complication incidence (47.4%vs. 16.7%, P=0.08) and postoperative stay time (22.1 ± 9.5 d vs. 17.2 ± 6.7 d, P=0.08). At body mass index (BMI)<25, the complication incidence (P=0.046) and postoperative stay time (P=0.051) were lower in the midline group than in the Mercedes group. Conclusion:Midline incision provided similar exposure in simultaneous resection for sCRLM and was better than Mercedes incision in rectal cancer patients. Patients with midline incision may attain better short-term outcomes if BMI is<25.

BACKGROUND:Core decompression may provide insufficient support for the subchondral bone in the treatment of early avascular necrosis of the femoral head and increase the risk of fracture and colapse. Quadratus femoris implantation cannot only provide good biological support, but also promote the revascularization at necrotic regions, thus repairing the necrosis of femoral head. OBJECTIVE: To compare the clinical effects of core decompression with bone paste implantation and core decompression with quadratus femoris implantation on early and middle-stage avascular necrosis of the femoral head. METHODS:Eighty-three patients with early avascular necrosis of the femoral head (92 hips) admitted at the Department of Orthopedics, the First Affiliated Hospital of Zhengzhou University, China, from January 2009 to January 2012 were enroled and divided into groups of core decompression with bone paste implantation (46 cases, 49 hips) and core decompression with quadratus femoris implantation (37 cases, 43 hips) that were respectively injected with bone meal and autogenous bone and osteoinductive materials. RESULTS AND CONCLUSION: Al involved patients were folowed up. After 1 year of treatment, Harris scores in the two groups were both increased (P < 0.05). But the Harris score of core decompression with bone paste implantation group was lower than that of core decompression with quadratus femoris implantation group (P < 0.05). After 3 years of treatment, X-ray scores in the core decompression with quadratus femoris implantation group were significantly higher than those in the core decompression with bone paste implantation group (P < 0.05). These findings indicate that compared with core decompression with bone paste implantation, core decompression with quadratus femoris implantation is better to prevent femoral head colapse, improve hip function and delay the process of osteonecrosis of the femoral head.
