ABSTRACT

Acetaminophen (APAP) overdose is a major cause of liver injury. Neural precursor cell expressed developmentally downregulated 4-1 (NEDD4-1) is an E3 ubiquitin ligase that has been implicated in the pathogenesis of numerous liver diseases; however, its role in APAP-induced liver injury (AILI) is unclear. Thus, this study aimed to investigate the role of NEDD4-1 in the pathogenesis of AILI. We found that NEDD4-1 was dramatically downregulated in response to APAP treatment in mouse livers and isolated mouse hepatocytes. Hepatocyte-specific NEDD4-1 knockout exacerbated APAP-induced mitochondrial damage and the resultant hepatocyte necrosis and liver injury, while hepatocyte-specific NEDD4-1 overexpression mitigated these pathological events both in vivo and in vitro. Additionally, hepatocyte NEDD4-1 deficiency led to marked accumulation of voltage-dependent anion channel 1 (VDAC1) and increased VDAC1 oligomerization. Furthermore, VDAC1 knockdown alleviated AILI and weakened the exacerbation of AILI caused by hepatocyte NEDD4-1 deficiency. Mechanistically, NEDD4-1 was found to interact with the PPTY motif of VDAC1 through its WW domain and regulate K48-linked ubiquitination and degradation of VDAC1. Our present study indicates that NEDD4-1 is a suppressor of AILI and functions by regulating the degradation of VDAC1.

ABSTRACT

Objective: To observe the effects of tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder on pain and shoulder joint function in subacromial impingement syndrome (SIS). Methods: Eighty patients with SIS were recruited and divided into a control group and a treatment group by the random number table method, with 40 cases in each group. The control group was given JIN's three-needle therapy for the shoulder, and the treatment group received additional tendon-regulating and stretching manipulation. The visual analog scale (VAS) score and constant-Murley score (CMS) were observed before and after the intervention, and the total effective rate was also observed. Results: The total effective rate was 92.5% in the treatment group versus 70.0% in the control group, and the difference was statistically significant (P<0.05). The VAS score and CMS changed notably after treatment in both groups (P<0.05), and the improvements were markedly greater in the treatment group than in the control group (P<0.05). Conclusion: Tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder can facilitate the relief of pain and the improvement of shoulder joint function in SIS patients.

ABSTRACT

【Objective】 To establish and verify a nomogram model of overall survival (OS) of prostate cancer patients based on the SEER data. 【Methods】 A total of 12 642 patients diagnosed with prostate cancer during 2010 and 2015 were extracted from the SEER database. Patients were randomly divided into the model group (n=8 850) and validation group (n=3 792). The independent risk factors for OS were analyzed with univariate Cox proportional risk regression, lasso regression and multivariate Cox proportional risk regression. A nomogram was constructed to predict the 1-year, 3-year and 5-year OS. The prediction potential of the model was evaluated with the consistency index (C-index), calibration curve and receiver operating characteristic (ROC) curve. 【Results】 Multivariate Cox regression analysis showed that age, T stage, N stage, M stage, bone metastasis, liver metastasis and regional lymphadenectomy were independent risk factors for OS (P<0.05). The seven factors were used to construct an OS nomogram model. The C-index of the modeling set was 0.750, and the area under the ROC curve (AUC) at 1, 3 and 5 years were 0.77, 0.77 and 0.76, respectively;the C-index of the validation set was 0.765, and the AUC at 1, 3 and 5 years were 0.83, 0.79 and 0.76, respectively. The calibration curves of the modelling set and validation set showed a good agreement with the actual survival prediction rate. Risk stratification of patients based on the nomogram model showed that the OS of patients in the high-risk group was significantly lower than that in the low-risk group (P<0.001). 【Conclusion】 The nomogram can be used to predict the prognosis of prostate cancer patients, and is important for individualized treatment plans.

ABSTRACT

ObjectiveTo observe the effects of five Huoxue Huayu prescriptions on blood lipid metabolism, liver tissue and adenosine triphosphate binding cassette transporter A1 (ABCA1) and peroxisome proliferator-activated receptor γ(PPARγ) expression in New Zealand rabbits with blood stasis syndrome, and to compare their differences in order to provide laboratory evidence for clinical selection of prescriptions and drugs. MethodSeventy New Zealand rabbits were randomly divided into normal group (n=10) and model group (n=60). The blood stasis syndrome was modeled by the method of starvation+high-fat feed+adrenaline. After the models were successfully established, they were randomly divided into Xuefu Zhuyutang(3.55 g·kg-1·d-1) group, Danshenyin(1.962 g·kg-1·d-1) group, Shixiaosan(0.56 g·kg-1·d-1) group, Huoluo Xiaolingdan(2.80 g·kg-1·d-1) group, and Taohong Siwutang(2.66 g·kg-1·d-1) group, and were given corresponding compound prescriptions by gavage. The normal group and model group were given the same dose of distilled water. After the treatment of 30 consecutive days, blood was taken from the abdominal aorta to detect the content of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol(LDL-C) and apolipoprotein A1 (ApoA1). Hematoxylin-eosin(HE) staining was used to observe the changes in liver tissue. Real-time polymerase chain reaction (Real-time PCR) and Western blot were used to detect the mRNA and protein expression of ABCA1 and PPARγ in liver tissue, respectively. ResultCompared with the conditions in the normal group, increased mRNA and protein levels of HDL-C, LDL-C, TG, TC, and PPARγ (P<0.01), decreased ApoA1 level (P<0.05) and decreased mRNA and protein levels of ABCA1 (P<0.01) were found in the model group. Compared with the conditions in the model group, the HDL-C level in the five Huoxue Huayu prescriptions was lowered (P<0.05), and lowered TG level in Xuefu Zhuyutang group and Shixiaosan group (P<0.05), decreased LDL-C and TC levels in Shixiaosan group (P<0.05), and increased ApoA1 level in the Huoluo Xiaolingdan group (P<0.01) and Taohong Siwutang group (P<0.05) were observed. Furthermore, the mRNA and protein levels of ABCA1 in Xuefu Zhuyutang group, Shixiaosan group, Huoluo Xiaolingdan group and Taohong Siwutang group were elevated (P<0.05, P<0.01), and the elevated levels were higher than that of Danshenyin group (P<0.05). The mRNA level of PPARγ in the five Huoxue Huayu prescriptions was reduced (P<0.01), and its protein level was also decreased in Xuefu Zhuyutang group, Shixiaosan group, Huoluo Xiaolingdan group and Taohong Siwutang group (P<0.01). ConclusionThe five Huoxue Huayu prescriptions had a certain therapeutic effect on dyslipidemia,which might be achieved by up-regulating the expression of ApoA1 and ABCA1 to promote the production of HDL-C and strengthen the excretion of dysfunctional HDL-C. And Xuefu Zhuyutang had the optimal effect in lowering lipid.

ABSTRACT

Objective To observe the effect of electroacupuncture (EA) pretreatment of different durations on the expressions of AQP4 and CLN5 in the blood-brain barrier after cerebral ischemia and reperfusion Methods Sixty-four male Sprague-Dawley (SD) rats were randomly divided into a model group,a sham operation group,a 7-day EA-pretreatment group (EAP-7 group) and a 15-day EA-pretreatment group (EAP-15 group),each of 16.After EA-pretreatment on the baihui and shuigou acupoints for 7 days or 15 days,a model of unilateral middle cerebral artery embolism (MCAO) model was induced in the rats of the model,EAP-7 and EAP-15 group using a modified Longa method.In the sham operation group the carotid artery was separated without middle cerebral artery embolism.The reperfusion was begun 90 min after the MCAO modeling.Immunohistochemical methods and fluorescence quantitative PCR were applied to detect the expression of AQP4,CLN5 and their mRNAs expression in the blood brain barrier (BBB) 24h after the operation.Results Compared with the sham operation group,the expression of AQP4 positive cells and AQP4 mRNA in the BBB in the other three groups had increased significantly,while the expression of CLN5 positive cells and CLN5 mRNA was significantly less.Compared with the model group,the expression of AQP4 positive cells and AQP4 mRNA in the EAP-7 and EAP-15 groups was significantly reduced,while the expression of CLN5 positive cells and CLN5 mRNA was significantly increased.Moreover,the expression of AQP4 positive cells and AQP4 mRNA in the EAP-15 group were significantly higher than in the EAP-7 group,while the expression of CLN5 positive cells and CLN5 mRNA were significantly lower.Conclusions EA-pretreatment on the baihui and shuigou acupoints can restrain the expression of AQP4-positive cells and AQP4 mRNA and promote that of CLN5-positive cells and CLN5 mRNA in the BBB after cerebral ischemia and reperfusion,at least in rats.The BBB protection effect is better when the EA-pretreatment lasts longer.The mechanisms of cerebral ischemia tolerance may be related to the regulation of AQP4,CLN5 and their mRNAs in the blood-brain barrier after cerebral injury.

ABSTRACT

Objective To establish a novel method to detect autoantibodies against platelatespecific receptors by flow cytometric bead assay and study its clinical application. Methods The beads were coated with monoclonal antibodies SZ2, SZ22, SZ21 and 7E3 against platelet GP Ⅰ b, GP Ⅱ b, GP Ⅲa and GP Ⅱ b/Ⅲ a, respectively. Captured platelet glycoprotein and beads complex was detected by FITC labeled polyclonal goat antihuman immunoglobulin using flow cytometer. The platelet samples that reacted with antibodies (SZ2, SZ22, SZ21 and 7E3) negatively and positively were tested, respectively. Each sample was repeated 20 times to generate intra-day CV for the MFI and once a day for 8 days to generate inter-day CV values. The 85 ITP patients, 17 NITP patients and 50 controls from the First Affiliated Hospital of Soochow University during March 2006 to December 2008 were included in the studies. The sensitivity and specificity of these four platelet antibodies to diagnose ITP were analyzed using ROC curve. The results were compared with MAIPA. Results The CV of the intra-day-assay for samples negative to antibody SZ2, SZ22,SZ21 and 7E3 were 3.26%, 2. 86%, 1.65% and 4. 94%, respectively; While the CV of the intra-day-assay for samples positive to antibody SZ2, SZ22, SZ21 and 7E3 were 6. 16%, 4. 88%, 5.20% and 5. 85%,respectively. The CV of the inter-day-assay for samples negative to antibody SZ2, SZ22, SZ21 and 7E3 were 5. 86%, 4. 74%, 5.69% and 7.56%, respectively; While the CV of the inter-day-assay for samples positive to antibody SZ2, SZ22, SZ21 and 7E3 were 7.53%, 5.49%, 7.11% and 6.25%,respectively. The MFI for SZ2 in ITP group, NITP group and healthy control group were 1.49(0. 88-16. 24),1.12(1.00-1.33), 1.01 (0. 83-1.37), respectively, which showed significant differences (H = 36.89,P<0.01). The MFI for SZ22 in the three groups were 1.55 (0.84-11.30), 1.13(1.03-1.29), 0.98(0. 85-1.24), respectively (H=28.41, P <0.01). The MFI of SZ21 were 1.50 (0.87-11.04), 1.13(0.97-1.32), 1.05 (0.85-1.48), respectively (H=54.42, P<0. 01). The MFI for7E3 were 1.51(0. 84-9.81), 1.05(0.86-1.13), 1.03 (0.74-1.28), respectively (H =31.97, P <0.01). Based on ROC analysis, with cut-off values of 1.37, 1. 24, 1.48 and 1.28 for SZ2, SZ22, SZ21 and 7E3,respectively, the AUC were 0. 86, 0.90, 0. 87 and 0. 84, respectively. The sensitivities of the assays were 58. 82% (50/85), 52. 94% (45/85), 52.94% (45/85) and 51.76% (44/85), respectively. When all four antibodies were used, the sensitivity was increased to 74. 12% (63/85), which was higher than that of MAIPA [ 50. 59% (43/85) ,χ2 = 6. 78, P < 0. 05) ]. Conclusion Flow cytometric bead assay can be used to detect four platelet-specific autoantibodies simultaneously, and may be a useful method to aid in the diagnosis of ITP.
