Objective To investigate the role of serum and glucocorticoid regulated protein kinase (SGK) 1 in the inflammatory responses mediated by toll like receptors.Methods Mice were injected with lipopolysaccharide (LPS,1 mg/kg) 2 h after the pretreatment of EMD638683 (10 mg/kg) or phosphate buffered saline (PBS) as control.At the time points of 3 and 24 h,pro-inflammatory cytokines (interleukin [IL]-6,IL-12 and tumor necrosis factor [TNF]-α) in serum were measured using enzymelinked immunosorbent assay (ELISA).Livers and lung were harvested at 6 h and 24 h after the injection of LPS,embedded by optimum cutting temperature (OCT) and then stained with hematoxylin and eosin (HE).Peripheral blood mononuelear cell (PBMC) were isolated and stimulated by LPS with or without the pretreatment of EMD or LY294002.Cytokines (IL-6,IL-12 and TNF-α) were measured using ELISA.IKKα/β,IKBα and nuclear factor (NF)-κB p65 were detected by Western bolt.Data were analyzed by one way analysis of variance.Results In the model of LPS-induced endotoxin sepsis,inhibition of SGK1 induced secretion of pro-inflammatory cytokine (IL-6 [t=3.007,P＜0.05],IL-12[t=4.413,P＜0.05] and TNF-α[t=5.403,P＜0.05]),increased inflammatory cells infikration into the liver and lung within 6 h,and induced serious multiple organ damage with collapse of alveoli and fatty degeneration of liver.After 24 h,pharmacological inhibition of SGK1 with EMD638683 increased proinflammatory cytokine (IL-6 [t=18.540,P＜0.01],IL-12[t=16.520,P＜0.01] and TNF-α[t=34.880,P＜0.01]) production in human PBMC upon LPS stimulation and inhibited the phosphorylation of IKKα/ β/IKBα and nuclear factor (NF)-κB p65.Conclusions SGK1 suppresses the toll like receptor 4 mediated inflammatory responses via NF-κB.

Objective To explore the role of somatosensory evoked potentials elicited by paraspinal stimulation in the detection of spinal cord lesions.Methods Patients with clinically suspected spinal cord lesions underwent somatosensory evoked potentials(SEPs)and spinal cord conduction velocity(SCCV)test using paraspinal stimulating method.96 patients aged 15 to 75 years old with suspected spinal cord lesions of various aetiologies were tested.36 patients had demyelinating disease of the spinal cord,26 had sub-acute combined degeneration of the spinal cord,19 had myelopathy,10 had acute myelitis,5 had spinal cord corhpression.Results Paraspinal stimulation elicited somatosensory evoked potentials were Performed on all 96 patients,68 of whom underwent spinal MRI as well.SEPs and SCCV were found abnormal in a high ratio in all kinds of spinal cord lesions ; in general,78 among the 96 patients had abnormal SEPs with a sensitivity of 81.25%.27 out of 36 with demyelinating disease of the spine had abnormal SEPs with a sensitivity of 75.00%,23 out of 26 with subacute combined degeneration of the spinal cord had abnormal SEPs with a sensitivity of 88.46%,8 out of 10 with acute myelitis had abnormal SEPs,15 patients with myelopathy having abnormal findings,all 5 patients with spinal cord compression had abnormal SEPs.42 of 68 patients undergoing MRI revealed to be abnormal,in which 35 patients also had abnormal SEPs.The other 26 patients had normal spinal MRI,in which 21 patients had abnormal SEPs.Conclusions Paraspinal stimulation somatosensory evoked potentials and spinal cord conduction velocity may objectively document the abnormalities of electrophysiology,which occurs earlier than those of anatomy and radiological finds, therefore it may detect the dysfunction of spinal cord at an early stage.It is even more useful in the detecting of the metabolic myelopathy,which can hardly be detected by MRI.This technique is simple,inexpensive, and maybe useful in the diagnosis for patients with suspected spinal cord lesions.

Objective:To evaluate the short-term prognostic value of model for end-stage liver disease (MELD) combined with high density lipoprotein-cholesterol (HDL-C) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:From December 2015 to December 2018, 182 patients with HBV-ACLF who were treated in Henan Provincial People′s Hospital were included. Prognosis and clinical data including HDL-C, total bilirubin, international standardized ratio (INR), creatinine of patients within 24 hours after admission were collected and analyzed retrospectively.The values of MELD were calculated. The binary logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients.The receiver operator characteristic curve (ROC) and MedCalc 15.2 software were used to assess the predictive value of MELD, HDL-C and MELD-HDL-C model for prognosis. Kaplan-Meier survival curve was performed to analyze the prognosis of patients in different groups.Results:Sixty patients were divided into the death group and 122 patients were divided into the survival group according to the prognosis during hospitalization and 90 days after discharge. The MELD score of patients in the survival group was 21(19, 24), which was significantly lower than that in the death group (29(25, 34)), and the HDL-C value of patients in the survival group was significantly higher than that in the death group (0.3 (0.1, 0.6) mmol/L vs 0.2(0.1, 0.5) mmol/L). The differences were both statistically significant ( Z=-6.290 and -4.087, respectively, both P<0.01). Multivariate logistic regression analysis showed that MELD score and HDL-C value were the independent risk factors for 90-day mortality in patients with HBV-ACLF(odds ratio ( OR)=1.432, 95% confidence interval ( CI)1.271-1.613; OR=0.584, 95% CI 0.487-0.700, respectively; both P<0.01). Areas under the ROC of MELD, HDL-C and MELD-HDL-C scoring models were 0.775, 0.782 and 0.878, respectively. MELD-HDL-C scoring model was superior to both MELD and HDL-C , and the differences were both statistically significant ( Z=3.944 and 3.104, respectively, both P<0.01). When the MELD-HDL-C Youden′s index was set at 0.72, the optimal threshold was 24.69. Patients with MELD-HDL-C score≥24.69 had lower survival rate than patients with MELD-HDL-C score<24.69, and the difference was statistically significant ( χ2=142.900, P<0.01). Conclusion:MELD, HDL-C and MELD-HDL-C scoring systems could predict the short-term prognosis in patients with HBV-ACLF, and the predictive value of MELD-HDL-C has the superiority.

Objective To investigate the virological response in hepatitis C virus (HCV)genotype 1b relapsers after 48 weeks of peginterferon/ribavirin (peg-IFN/RBV)combination retreatment,and to explore the predictive value of interleukin (IL )-28B rs12978960 genetic polymorphismon virological response.Methods From 2012 to 2014,genotype 1b chronic hepatitis C (CHC)relapsers in He′nan Provincial People′s Hospital were retreated with combined peg-IFN/RBV for 48 weeks and followed up for 24 weeks off-treatment.Host IL-28B genetic polymorphism was detected.Predictive factors associated with virological response and sustained virological response (SVR)were analyzed.Independent-samples t test was conducted in continuous variables,whileχ2 test or Fisher exact probability test was conducted in counts data.Results A total of 61 patients finished 48 weeks of peg-IFN/RBV combination therapy and were further followed up for 24 weeks off-treatment.Mean age was (46.7 ±12.4)years.Thirty-seven patients (60.7%)were male and 49 were rs12978960 CC genotype.After 48 weeks of retreatment with peg-IFN/RBV and 24 weeks of off-treatment follow-up,40 patients (65 .6%)achieved SVR.Rapid virological response (RVR)and SVR of younger patients were both significantly higher than those of older patients (100.0% vs 67.4% and 85 .0% vs 47.6%,respectively;both P =0.006).IL-28B rs12978960 genotype was predictive to RVR and SVR.Patients with RVR and SVR had higher carriage rates of IL-28B rs12978960 CC genotype compared with those without RVR and SVR (both P <0.05 ).Patients with CC genotype had higher rates of RVR (34.1 % vs 0;χ2 = 10.625 ,P =0.006 ),end-of-treatment virological response (84.1 % vs 70.6%;χ2 =5 .563,P =0.039 )and SVR (77.3% vs 35 .3%;χ2 =9.572,P =0.007)than those with CT/TT genotype.However,there were no statistical differences of extended RVR (34.1 % vs 29.4%;χ2 =0.122,P =0.809)and early virological response (79.5 % vs 82.3%;χ2 =0.612,P =0.964).Conclusions Retreatment with antiviral therapy is necessary in CHC patients with genotype 1b. IL-28B rs12978960 genetic polymorphism is predictive to the SVR of retreatment,especially for patients without RVR,which will provide individualized treatment and optimize the treatment strategy.

In this paper, microcrystalline cellulose WJ101 was used as a model material to investigate the effect of various process parameters on granule yield and friability after dry granulation with a single factor and the effect of comprehensive inspection process parameters on the effect of granule yield and friability, then the correlation between process parameters and granule quality was established. The regress equation was established between process parameters and granule yield and friability by multiple regression analysis, the affecting the order of the size of the order of the process parameters on granule yield and friability was: rollers speed > rollers pressure > speed of horizontal feed. Granule yield was positively correlated with pressure and speed of horizontal feed and negatively correlated rollers speed, while friability was on the contrary. By comparison, fitted value and real value, fitted and real value are basically the same of no significant differences (P > 0.05) and with high precision and reliability.

Objective To observe the effects of nAChR antagonistα-conotoxin Eb1.6 on ther-mal pain threshold and spinal IL-1βexpression levels and astrocytes activation in rats using L5 spinal nerve transaction (SNT)model.Methods Fifty male Sprague-Dawley rats were randomly assigned into 5 groups with each group 10 rats:sham group,different doses of α-CTX Eb1.6 (0.1 5,1.5 and 1 5 nmol/kg)groups and the saline group after SNT.Saline solution or different doses of Eb1.6 were intraperitoneally injected seven days after the surgery when the model was stable and the treatment continued for seven days.Measured the TWLs of all groups of the rats 1,2,4,7,12 hours after the in-jection on 7 d and 13 d.The rats were sacrificed and L5 spinal cord tissues were collected immediately after the behavioral tests on 13 d.The expression of GFAP and IL-1βwere assessed by Western blot assay and enzyme linked immunosorbent assay (ELISA)separately.Results Groups E1,E2,E3 and C had shorter TWL before the injection on 7 d and 13 d than group N(P <0.05).The TWLs of the rats in groups E1,E2 and E3 of 1 h,2 h and 4 h after the injection on 7 d were significantly higher than that before the injection(P <0.05)with 2 h after the injection showed the most obvious change.The TWL of 1 h,2 h,4 h and 7 h after the injection of the rats in group E1,E2 and E3 and those of 12 h after the injection of the rats in group E2 and E3 on 13 d were significantly higher than that before the injection(P <0.05 )and also higher than TWL of the respective time points on 7 d(P < 0.05 ),also with 2 h after the injection showed the most obvious change.The TWLs of 2 h after the injection a-mong group E1,E2 and E3 showed significant differences both on 7 d and 13 d (P <0.05).Rats spi-nal IL-1βand GFAP expression levels of group E1,E2,E3 and C were significantly higher than those of group N(P <0.05).Rats spinal IL-1β and GFAP expression levels of groups E1,E2,E3 signifi-cantly decreased compared with group C(P <0.05).There were significant differences among the spi-nal IL-1βand GFAP expression levels of group E1,E2 and E3(P <0.05).Conclusion Eb1.6 dose-de-pendently reduced the thermal hyperalgesia induced by L5 spinal nerve transection.Repeated treat-ment of Eb1.6 could produce better analgesic effect,which might be partly attribute to the inhibition of spinal IL-βlevels and astrocytes activation.

OBJECTIVETo investigate the correlation of the deleted azoospermia (DAZ) gene copy related to gr/gr and b2/b3 deletions in the AZFc region with male spermatogenic impairment.

METHODSThis study included 121 infertile men with different de- grees of spermatogenic impairment and 95 healthy donors from the sperm bank. Using PCR, PCR-RFLP, and Y chromosome specific sequence tagged sites (STS) , we analyzed the association of DAZ gene copy deletions related to gr/gr and b2/b3 deletions in the AZFc region with spermatogenic impairment.

RESULTSThere were 15 cases of gr/gr deletion (12. 40% ) and 6 cases of b2/b3 deletion (4.96%) in the infertility group as compared with 13 cases of gr/gr deletion (13.68%) and 1 case of b2/b3 deletion (1.05%) in the control. Analysis of the DAZ-specific single nucleotide variant (SNV) loci revealed 11 gr/gr-DAZI/DAZ2 deletions (9.09%), 4 gr/gr-DAZ3/DAZ4 deletions (3.31%), and 6 b2/b3-DAZ1/DAZ2 deletions (4.96%) in the infertile men in comparison with 3 gr/ gr-DAZ1/DAZ2 deletions (3.16%), 10 gr/gr-DAZ3/DAZ4 deletions (10.53%), and 1 b2/b3- DAZ3/DAZ4 deletion (1.05%) in the control.

CONCLUSIONPartial deletions of gr/gr and b2/b3 exist in both healthy men and male patients with different degrees of spermatogenic impairment and cannot be considered as a risk factor for spermatogenesis impairment. However, deletions of different DAZ duplicons in gr/gr and b2/b3 deletions have different effects on spermatogenesis. DAZ1/DAZ2 instead of DAZ3/DAZ4 deletions might be associated with spermatogenesis impairment.

Prostate cancer (PCa) is one of the most common malignant tumors as well as a frequent cause of cancer-related mortality in men worldwide. The test of serum markers has dramatically improved the early diagnosis of PCa, but its underlying molecular mechanisms are not yet completely identified. Long noncoding RNA (IncRNA) is emerging as a new player in the PCa paradigm demonstrating its potential roles in both oncogenic and tumor suppressive pathways. LncRNA is frequently aberrantly expressed in the majority of PCa cases. This review highlights recent findings of the aberrant expression of lncRNA in PCa and discusses its novel roles in the diagnosis, prediction, prognosis, metastasis, and potential clinical treatment of PCa.
