Objective To discuss the clinical effect of behavioral therapy combined with pramipexole in patients’ degree of depression and non-motor symptoms in early-onset Parkinson’s disease and depression.Methods A total of 74 cases of patients with early-onset Parkinson’s disease and depression were equally divided into observation group and control group, 37 cases in each groups.Patients in control group were given pramipexole, while patients in observation group were given pramipexole and behavioral therapy.The hamilton depression ( HAMD) scale, Zung self-rating depression scale and unified Parkinson’s disease rating scale ( UPDRS ) were used to evaluate and measure the change of degree of depression and non-motor symptoms.Results Before treatment, the HAMD score, Zung score, UPDRS II score and UPDRS III score between two groups had no statistical difference; after treatment, the HAMD score, Zung score, UPDRS II score and UPDRS III score in two groups were significantly decreased (P<0.05). The HAMD score, and Zung score between two groups had no statistical difference at the end of 4th weekends, and compared with control group, those scores in observation group were much better at the end of 8th and 12th weekend (P<0.05).The UPDRS II and UPDRS III between two group had no statistical difference at the end of 4-8th week, while those scores in observation group were better than those in control group at the end of 12th week(P<0.05).Conclusion Behavioral therapy combined with pramipexole has a great effect on the improvement of patients’ degree of depression and non-motor symptoms, which has a positive promotion on patients’ life quality.

Objective To evaluate the clinical significance of the changes of microalbunminuria(MAU) levels in mechanical ventilated patients with severe pneumonia. Methods According to the ratio between the microalbunminuria and the urine creatinine (MAU/CR) (ACR), setting 25mg/mmol as the threshold, 78 mechanical ventilated patients with severe pneumonia were divided into two groups :ACR increasing group and ACR Non-increasing group,then the clinical significance of changes of MAU levels in 72 hours on prognosis of these patients was observed. Results MAU increased in 64 cases(82. 1%) ,of which 46 cases in ACR increasing group and 18 cases in ACR non-increasing group. There showed statistically significant differences on APACHE Ⅱ score, CPIS score,PCT、the success of getting out of mechanical ventilation and the mortality between two groups, (t = 3.50、2. 19 、x~2 = 3. 95、6. 70、5.38 ,P = 0.01,0.03,0.04,0.01,0.02, all P ＜ 0.05). Conclusion Changes of MAU levels have the clinical significance on prognosis of the mechanical ventilated patients with severe pneumonia.

Objective To compare the efficacy of rcmifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.Methods We searched the Coehrane library,PubMed,EMBASE,OVID and Chinese Biomedical Database for prospective randomized controlled trials involving the comparison of the efficacy of remifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.The quality of the studies was evaluated by the method recommended by Cochrane Collaboration.Evaluation indexes included the mechanical ventilation time after operation,duration of stay in hospital,and level of cardiac troponin,mortality,requirement for positive inotropic drugs and incidence of hyperalgesia and myocardial infarction during perioperative period.Meta-analysis was conducted using the RevMan 5.0 software.Results Sixteen prospective randomized controlled trials involving 1473 patients were included in our Meta-analysis.The patients were divided into 2 groups:fentanyl or sufentanil group ( n =644) and remifentanil group ( n =573).Compared with fentanyl or sufentanil group,the mechanical ventilation time after operation and duration of stay in hospital were significantly shortened,the level of cardiac troponin during the perioperative period was significantly decreased and the requirement for positive inotropic drugs during the perioperative period was significantly reduced ( P ＜ 0.05),and no significant change was found in the incidence of hyperalgesia or mortality of myocardial infarction during the perioperative period in remifentanil group ( P ＞ 0.05 ).Conclusion The efficacy of remifentanil combined anesthesia is better than that of fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.

The antibody against AT1-EC2 plays a role in some kinds of inflammatory vascular diseases including malignant hypertension, preeclampsia, and renal-allograft rejection, but the detailed mechanisms remain unclear. In order to investigate the changes of NADPH oxidase and reactive oxygen species in the aorta in a mouse model which can produce AT1-EC2 antibody by active immunization with AT1-EC2 peptide, 15 mice were divided into three groups: control group, AT1-EC2-immunized group, and AT1-EC2-immunized and valsartan-treated group. In AT1-EC2-immunized group and AT1-EC2-immunized and valsartan-treated group, the mice were immunized by 50 μg peptide subcutaneously at multiple points for 4 times: 0, 5, 10, and 15 days after the experiment. In AT1-EC2-immunized and valsartan-treated group, valsartan was given at a dose of 100 mg/kg every day for 20 days. After the experiment, the mice were sacrificed under anesthesia and the aortas were obtained and frozen in liquid nitrogen for the preparation of frozen section slides and other experiments. The titer of AT1-EC2 was assayed by using ELISA. The level of NOX1 mRNA in the aorta was determined by using RT-PCR. The expression of NOX1 was detected by using Western blotting. Confocal scanning microscopy was used to assay the α-actin and NOX1 expression in the aortic tissue. The O(2)∸ production was detected in situ after DHE staining. The mice produced high level antibody against AT1-EC2 in AT1-EC2-immunized group and AT1-EC2-immunized and valsartan-treated group, and the level of NOX1 mRNA in the aortic tissues was 1.6±0.4 times higher and the NOX1 protein expression was higher in AT1-EC2-immunized group than in control group. There were no significant differences in the level of NOX1 mRNA and protein expression between control group and AT1-EC2-immunized and valsartan-treated group. The expression and co-localization of α-actin and NOX1 in AT1-EC2-immunized group increased significantly as compared with those in control group, and the O(2)∸ production increased about 2.7 times as compared with control group. There were no significant differences between control group and AT1-EC2-immunized and valsartan-treated group. It is concluded that active immunization with AT1-EC2 can activate NOX1-ROS, and increase vascular inflammation, which can be inhibited by AT1 receptor blocker valsartan. This may partially explain the mechanism of the pathogenesis of inflammatory vascular diseases related to antibody against AT1-EC2.

Objective To investigate the effect ofpeptidoglycan from Staphylococcus aureus on the release of several chemokines including intedeukin 8 (IL-8), regulated upon activation, normal T cell expressed and secreted (RANTES), macrophage-derived chemokine (MDC) by normal human epidermal keratinocytes (KCs) and the role of Toll-like receptor 2 (TLR2) in this process. Methods KCs were derived from the foreskin of a healthy boy and propagated. After 2 - 4 passages, KCs were collected and treated with various concentrations (3, 10, 30 and 100 mg/L) of peptidoglycan for 24 hours or with peptidoglycan of 100 mg/L for varying durations (3, 6, 12, 36 hours). A fi'action of KCs were pretreated with functional grade purified anti-TLR2 monoclonal antibody before the treatment with peptidoglycan of 100 mg/L. After additional 12-hour culture following the treatment, enzyme linked immunosorbent assay was used to detect the level of IL-8, RANTES and MDC in culture supernatants of KCs. Results KCs spontaneously released IL-8 and RANTES. Peptidoglycan increased the production of IL-8 but decreased that of RANTES by KCs. The levels of IL-8 were 209.96 ± 10.31 ng/L, 250.28 ± 9.52 ng/L, 285.11 ± 10.28 ng/L, 359.40 ± 6.93 ng/L in KCs treated with peptidoglycan of 3, 10, 30, 100 mg/L, respectively, compared to 135.41 ± 14.37 ng/L in untreated KCs (all P < 0.05). On the contrary, a significant decrement was seen in the secretion of RANTES by KCs treated with peptidoglycan of 10, 30, 100 mg/L compared with untreated KCs (110.72 ± 8.51 ng/L, 90.50 ±2.45 ng/L, 49.89 ± 13.74 ng/L vs 149.94 ± 18.71 ng/L, all P < 0.05). The monoclonal antibody to TLR-2 could markedly suppress the promotion of IL-8 production by peptidoglycan, but had no obvious influence on the inhibition of RANTES production by peptidoglycan. MDC could not be detected in the culture super-natants of KCs with or without peptidoglycan stimulation. Conclusion Peptidoglycan could inhibit RANTES secretion but induce IL-8 production by KCs likely via TLR2.

Objective To evaluate the efficacy and safety of posaconazole for preventing invasive fungal disease (IFD) in the aplastic anemia patients receiving allogeneic hematopoietic stem cell transplantation (HSCT). Methods A total of 46 aplastic anemia patients received allogeneic HSCT. They were treated with oral posaconazole 200 mg, three times a day from HSCT pretreatment to granulocyte recovery after transplantation. G test and GM test were done 1, 2 and 4 weeks after the end of posaconazole treatment, and chest CT scan repeated 4 weeks after the end of posaconazole treatment. Posaconazole prophylaxis was defined as successful if there were no clinical manifestations indicative of fungal infection. Results All the 46 patients experienced neutropenia. The median of absolute neutrophil count (ANC) nadir was 0.02 (0-0.05)×109/L for a median time of 10 (8-19) days. The median duration of posaconazole prophylaxis was 26 (15-41) days. Neutropenic fever was reported in 45 patients, which lasted a median time of 5 (1-13) days. Six patients (13.3％ of the patients with neutropenic fever) failed to respond to the empirical treatment of broad spectrum antibiotics with persistent fever over 7 days. Their treatment was switched to short-term empirical treatment with broad spectrum antifungal agents. However, subsequent G test, GM test and chest CT showed negative results. None of the six patient was consistent with IFD diagnosis. Breakthrough fungal infection was not considered. Oral posaconazole solution was resumed for preventing IFD. G test, GM test and chest CT scan did not show any sign of fungal infection 1, 2 and 4 weeks after the end of posaconazole prophylactic treatment in all the 46 patients, proving the success of oral posaconazole in preventing IFD. Posaconazole was not discontinued due to adverse drug reaction in any patient. Conclusions Posaconazole is effective for preventing IFD in the aplastic anemia patients receiving HSCT with good safety profile and few adverse reactions.

Objective:To investigate the role of microRNA (miR)-497 in the formation of corneal neovascularization (CNV) induced by alkali burn and its mechanism.Methods:Forty-two wild type (WT) C57BL/6 mice aged 6 to 8 weeks, 42 CRISPR/Cas9 mediated miR-497 knockout (KO) and 42 CRISPR/Cas9 mediated overexpression transgenic (TG) C57BL/6 mice were selected and assigned as WT group, KO group and TG group, respectively.The corneal alkali burn model was established.At 3, 7, 14 and 21 days after modeling, corneal epithelium damage and stromal turbidity were scored according to slit lamp microscopy.The area of neovascularization was measured.Corneal structural changes and expression of inflammatory cells were observed by histopathological staining.The expression of CD31 in corneal tissues was detected by immunohistochemistry staining.The targeted binding relationship between miR-497 and signal transducer and activator of transcription 3 (STAT3) was detected by luciferase reporter assay.The relative expressions of miR-497, vascular endothelial growth factor A (VEGFA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β and macrophage inflammatory protein (MCP)-1 mRNA were detected by real-time quantitative PCR.At 14 days following modeling, the expression of STAT3 and p-STAT3 proteins in mice corneal tissues was detected by Western blot.The use and care of animals complied with the ARVO statement.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.2019K-K010).Results:Corneal injury, inflammatory cell infiltration and CNV occurred in mice cornea after alkali burn.Corneal epithelial injury score, corneal stromal turbidity score and CNV area increased first and reached the peak on the 14th day after modeling, and then decreased.There were significant differences in corneal epithelial injury score, corneal stromal turbidity score, CNV area and number of CD31-positive cells among various time points after alkali burn ( Fgroup=49.19, 34.56, 44.56, 77.56; all at P<0.01; Ftime=51.62, 65.62, 71.32, 46.12; all at P<0.01). Corneal epithelial injury score, corneal stromal turbidity score, CNV area and the number of CD31-positive cells were greater in KO group at various time points than in WT and TG groups, and those in WT group were greater than in TG group (all at P<0.05). In WT STAT3 co-transfected cells, the luciferase activity of the miR-497 group was significantly lower than that of the miR-negative control group and normal control group (both at P<0.05). In mutant STAT3-transfected cells, there was no significant difference in luciferase activity among all groups ( F=0.69, P=0.56). On the 14th day after modeling, the relative expression levels of miR-497 in corneal tissue of WT, KO and TG groups were 0.68±0.11, 0.41±0.06 and 1.05±0.14, respectively, which were significantly lower than 1.00±0.04, 0.56±0.07 and 1.34±0.11 before modeling (all at P<0.01). The relative expressions of STAT3 and p-STAT3 were higher in KO group than in WT and TG groups, and were lower in TG group than in WT group, and the differences were statistically significant (all at P<0.05). The expressions of VEGFA, TNF-α, IL-6, IL-1β and MCP-1 mRNA at various time points after modeling in various groups were significantly higher than before modeling, which were higher in KO group than in WT and TG groups and were lower in TG group than in WT group, and the differences were statistically significant (all at P<0.01). Conclusions:MiR-497 inhibits corneal inflammation and CNV formation induced by alkali burn.It might inhibit the activation of the inflammation signal pathway via targeting STAT3.
