Objective To analyze the effects of different doses of naloxone on resuscitation of patients with quality of dezocine anesthesia.Methods 84 patients with dezocine anesthesia surgery were selected and divided into three groups in accordance with the use of naloxone plus volume,28 cases in each group.All patients were treated with vein injection of propofol,fentanyl and Shun type atracurium for induction of anesthesia,endotracheal intubation and mechanical ventilation were given dezocine infusion to maintain anesthesia.After the operation,the high dose group was given 14μg/kg naloxone,the low dose group was given 7μg/kg naloxone,and the control group only received intravenous infusion of the corresponding measurement.Mean arterial pressure (map),heart rate (HR)before anes-thesia,recovery,extubation and intubation after 10min of three groups were observed.Pain and sedation situation score of the patients regained consciousness after 1min,1h,2h were received by visual analogue scale (VAS),sedation/restlessness score (SAS).At the same time,the incidence of complications and adverse reactions of the three groups were recorded.Results There were no significant differences in MAP and HR indexes among the three groups before anesthesia.At resuscitation and extubation there were no differences in MAP and HR between the low dose group and the control group (all P >0.05).However,resuscitation,extubation,MAP and HR were significantly lower in the low dose group than those in the high dose group (all P <0.05).The difference of VAS,SAS score had no statistical sig-nificance between the low dose group waken up each time and control group,but the VAS,SAS score in the high dose group waken up each time were significantly higher than those in the control group and low dose group(all P <0.05). The respiratory inhibition in the high dose group and low dose group were significantly lower than those of the control group(0,3.57% and 10.71%;χ2 =4.169,1.077,all P <0.05),but nausea and vomiting in the high dose group were higher than those in the control group and low dose group(all P <0.05).Conclusion Different doses of nalox-one could be used for patients using dezocine anesthesia according to patients after operation,to reduce respiratory inhibi-tion,and help patients relieve pain and agitation,and the recommend dose of naloxone is 7μg/kg.

Three hundred and thirty eight patients with type 2 diabetes mellitus( DM) admitted from January 2006 to June 2009 and 50 healthy subjects (control group) were enrolled in the study. Platelet glycoprotein PAC-1 and CD62P levels were measured in both groups. Compared with control group, plasma PAC-1 and CD62P levels of DM patients increased significantly (P ＜0.01). Patients were divided into three groups according to their urinary albumin excretion rate ( UAER) . PAC-1 and CD62P levels in macroalbuminuria group (UAER≥200μg/min) were significantly higher than those in normoalbuminuria group( UAER <20μg/min) and microalbuminuria group (20μg/min≤UAER ＜ 200μg/min) (both P＜ 0.05). The results indicate that plasma levels of PAC-1 and CD62P, which reflect platelet activation, are the independent risk factors for diabetic nephropathy.

AIM:To investigate the effect of Dachengqi decoction(DD)on the acute respiratory distress syndrome(ARDS)in rat model induced by endotoxin "two-hit".METHODS:48 healthy male Wistar rats were randomly divided into 4 groups:control group,ARDS model group,ARDS+DD treatment group and ARDS+dexamethasone treatment group(12 in each group).E.coli lipopolysaccharide(LPS)"two-hit" induced ARDS model in rats was established.The arterial blood gas analysis,lung wet/dry weight(W/D)ratio and lung tissue pathology observation and scoring were measured to evaluate the pharmacological effects of DD on ARDS.The levels of TNF-?,IL-1 and IL-10 were determined by ELISA to explore the immune regulatory mechanism of DD.RESULTS:(1)Treatment with DD significantly improved blood pressure in rats,increased oxygen saturation,decreased lung wet/dry weight ratio and lung injury score,relieved pulmonary edema and the inflammatory responses.(2)DD suppressed the productions of systemic and pulmonary pro-inflammatory mediators and promoted the release of anti-inflammatory mediators in lung.CONCLUSION:The inhibitory effects of DD treatment on pulmonary inflammatory response are not only related to reducing the extent of systemic inflammatory response,but also promote pulmonary anti-inflammatory production and regulate the balance of pulmonary pro-inflammatory mediators and anti-inflammatory cytokines.This specific regulatory effect protects the target organ from excessive inflammatory organ injury,discloses that DD has advantages in the treatment of endotoxic ARDS.

OBJECTIVETo observe the effective mechanism and side effects of thalidomide to multiple myeloma (MM).

METHODSTen cases of MM were studied, of which 3 were previously untreated and 7 refractory or relapsed. Bone marrow microvascular density (MVD) was detected by factor-VIII related antigen and CD(34) immunohistological staining and serum concentration of vascular endothelial growth factor (VEGF) before and after treatment was determined by ELISA. The initial dosage of thalidomide was 100 approximately 200 mg/d with a weekly escalation of 50 mg/d to 450 approximately 650 mg/d. The therapeutic effectiveness is classified into partial remission, improvement and uneffective according to the decrease of serum M protein and bone marrow myeloma cells. Anemia, renal function and blood electrolytes were also observed.

RESULTSBefore treatment, MVD was 73.32 +/- 28.80 and 32.30 +/- 12.50 in MM and control group, respectively, (P < 0.01). MVD in MM group decreased to 56.12 +/- 19.34 after treatment, and was of significant difference (P < 0.05) as compared to the pretreatment value. However, there was still a significant difference as compared to control (56.12 +/- 19.34 vs 32.30 +/- 12.50, P < 0.01). The concentration of VEGF significantly decreased after treatment [from (178.23 +/- 26.56) ng/L to (78.48 +/- 19.98) ng/L, P < 0.01)]. The total effective rate was 70%. There were no serious side effects.

CONCLUSIONMVD and VEGF concentration were decreased obviously by thalidomide treatment. The dosage of 450 approximately 650 mg/d might be effective in refractory or initial MM.

Objective:This study investigates the expression of long non-coding RNA termed amine oxidase, copper containing 4, pseudo-gene (AOC4P) in hepatocellular carcinoma (HCC) and its relationship with clinicopathological factors and patient prognosis. Methods:The expression of AOC4P in 106 HCC tissues and adjacent non-tumor tissues were detected using qRT-PCR. The relationship between AOC4P expression and clinicopathological factors, as well as patient prognosis, in HCC was analyzed. Results:The relative expression of AOC4P in the cancer tissues was 0.66±0.34, which was significantly lower than the relative expression in adjacent non-tumor tissues, i. e., 1.45±0.63 (P<0.05). Univariate analysis showed that low AOC4P expression was correlated with tumor size, lymph node metastasis, and TNM stage (P<0.05). The group with high AOC4P expression levels has longer survival time compared with the group with low AOC4P expression levels. Cox multivariate regression analysis showed that AOC4P expression, lymph node metastasis, and vascular in-vasion were all independent factors that affect prognosis of patients. Conclusion:AOC4P expression was reduced in HCC tissues, and AOC4P may play crucial roles in the occurrence and development of HCC. For patients with poor prognosis, low AOC4P expression is an independent risk factor for patients with HCC. Thus, AOC4P expression may be used as a molecular marker for HCC.

To investigate whether saikosaponin-d (SSd) had estrogen-like effects in mice.

Objective To study programmed death-1 (PD-1) and T-cell immunoglobulin mucin3 (Tim-3) co-expression on peripheral blood mononuclear cells (PBMC) and hepatitis B virus (HBV)-specific CD8+ T cells in patients with chronic HBV infection and its correlation with liver inflammatory activities.Methods One hundred and sixty subjects with chronic HBV infection who visited the outpatient and inpatient Department of Infectious Diseases in the Third Affiliated Hospital of Sun Yatsen University were enrolled,including 63 cases of mild or moderate CHB (MCHB),31 of severe CHB (SCHB),55 of acute-on-chronic liver failure (ACLF) and 11 inactive HBsAg carriers.Twenty healthy subjects were enrolled as controls.Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect HBV DNA,enzyme-linked immunosorbent assay (ELISA) to measure HBV serological markers,and flow cytometry to detect human leukocyte antigen (HLA)-A2 and determine the expression of PD-1 and Tim-3 on PBMC and HBV-specific CD8+ T cells.Cell counts of Tim-3+,PD-1+,and Tim-3+/PD1+ PBMC and HBV-specific CD8+ T cells were compared among different groups,and their correlation with commonly used inflammatory activity indicators were studied.Analysis of variance and Kruskal-Wallis test were used for measurement data with gaussian distribution and skewed distribution,respectively.Spearman correlation analysis was used to assess the association between Tim-3/PD-1 expression and inflammatory activity indicators.Results The frequency of Tim-3+/PD-1+ PBMC was 0.25 ％ in ACLF group (P=0.0049),0.24 ％ in SCHB group (P-0.0025) and 0.13％ in MCHB group (P=0.0006),which were significantly higher than that in control group (0.03％),and the frequency of Tim-3 /PD-1-PBMC in the three groups were significantly lower than that in control group (P =0.0000),but the differences between HBsAg carriers (0.10％) and controls (0.03％) were not statistically significant (P=0.28).Among 160 subjects,78 were HLA-A2 positive.The frequency of Tim-3+/PD-1+ HBV-specific CD8+ T cells was 68.72％±17.21％ in ACLF group,and 59.66％± 19.25％ in SCHB group,which were significantly higher than that in HBsAg carrier group (33.93％ ± 10.80％,P=0.0000,P=0.0054).The frequency of Tim-3 /PD-1-HBV-specific CD8+ T cells in ACLF group was 2.80％,which was significantly lower than that in HBsAg carrier group (27.24％,P=0.0004).The frequency of Tim3+/PD-1+ HBV-specific CD8+ T cells was positively correlated with alanine aminotransferase (r=0.26,P=0.022),aspartate aminotransferase (r=0.28,P=0.012) and total bilirubin levels (r=0.36,P=0.001); and inversely correlated with albumin level (r=-0.35,P=0.002) in serum.Furthermore,it was positively correlated with international normalized ratio (INR,r=0.34,P =0.045) and model for end-stage liver disease score (r=0.43,P=0.027) in ACLF group.Conclusions Co-expressions of Tim-3 and PD-1 on PBMC and HBV-specific CD8+ T cells are significantly upregulated in patients with CHB,and correlated with liver inflammatory activities.These findings indicate that Tim-3 and PD-1 co-expression may involve in disease activity and liver failure in CHB.
