15 scores were randomly divided into therapeutic group (30 cases)and control group(30 cases).The two groups were treated with the same conventional therapy. From the 1st day of admission,Xuebijing injection 80 ml was given by intravenous drip once for every 12 hours for 7 days to the therapeutic group.The level of tumor necrosis factor-?(TNF-?),interleukin-1?(IL-1?),IL-6,IL-10,and APACHEⅡscore were tested on 1,3,5 and 7 days after admission.The case fatality and incidences rates of sepsis and MODS in both groups were recorded.Results Compared with the control group,APACHEⅡscore,TNF-?,IL-1?,IL-6 and IL-10 of the therapeutic group were lower significantly on the 3rd day after admission,especially on the 5th day(all P

To observe the expression of cyclin D1, hTERT, and telomerase activity in MNC, HL-60, HL-60A and to explore their effects on leukemogenesis and drug-resistance, normal human peripheral blood mononuclear cells, HL-60 cells sensitive to adriamycin and HL-60A cells resistant to adriamycin were investigated. The cell cycle was analyzed by flow cytometry, and the apoptosis was analyzed by Annexin V-FITC(+) PI staining. Expressions of cyclin D1 and hTERT were determined by real-time PCR and Western blot. Telomerase activity was detected by TRAP-ELISA. The results indicated that the percentage of MNC, HL-60 and HL-60A in S phase was (10.21 + 2.11)%, (44.93 + 3.00)%, and (51.38 + 1.10)% respectively; the percentage of apoptosis cells was (16.14 + 2.13)%, (7.53 + 0.92)%, (4.15 + 0.96)% respectively; the expression of mRNA and protein for cyclin D1 and hTERT increased; the telomerase activities of HL-60 and HL-60A were higher (p = 0.000), whereas the difference between HL-60 and HL-60A was no statistically significant (p = 0.232); positive correlation between cyclin D1, hTERT and telomerase activity had been found (p < 0.01). It is concluded that the cells of S phase increased while the apoptotic cells decreased in HL-60 and HL-60A, especially in HL-60A, which may be due to the up-regulation of cyclin D1, hTERT and telomerase activity.

OBJECTIVETo explore the effect of serum restriction on the invasiveness and expressions of insulin-like growth factor-1 (IGF-1) and matrix metalloproteinase-2 (MMP-2) in human trophoblast HTR-8/SVneo cells in vitro.

METHODSHTR-8/SVneo cells were cultured in the presence of 1%, 5%, or 10% fetal bovine serum (FBS) for 48 h. Fluorescence quantitative PCR and immunofluorescence staining were employed to examine the changes in IGF-1 and MMP-2 expressions at both the mRNA and protein levels in HTR-8/SVneo cells; MTT assay and Transwell invasion assay were used to assess the changes of the cell proliferation and the cell invasion ability, respectively. MMP-2 expression, cell proliferation and invasiveness were also assessed in the cells treated with recombinant human IGF-1.

RESULTSHTR-8/SVneo cells exhibited significantly lowered cell proliferation in cultures containing low concentrations of FBS (P<0.05). The expressions of IGF-1 and MMP-2 at both mRNA and protein levels were significantly down-regulated and the invasiveness was significantly lowered in cells cultured in the medium containing 1% FBS as compared with those of cells cultured in the presence of 5% and 10% FBS (P<0.05). Treatment of the cells with recombinant human IGF-1 significantly up-regulated MMP-2 expression (P<0.05) and increased the cell invasiveness (P<0.05).

CONCLUSIONSFBS restriction down-regulates IGF-1 expression in human trophoblast HTR-8/SVneo cells and suppress the cell invasiveness possibly by suppressing MMP-2 expression. Treatment with recombinant human IGF-1 can up-regulate MMP-2 expression and promote the invasiveness of HTR-8/SVneo cells.

[Objective]Examine the expression of microsomal prostaglandin E synthase-1(mPGES-1)and nuclear transcription factor kappa B p65(NF-κB p65)in diffuse large B cell lymphoma(DLBCL),assessing their correlation with clinical variables,prognosis and potential clinical valve.[Methods]The immunohistochemistry was uesd to investigate the expression of mPGES-1 and NF-κB p65 in 83 DLBCL patiens'tissues.The relationship between these two proteins and the clinical variables and prognosis of these patients was evaluated.[Results]The high expression of mPGES-1 and NF-κB p65 were observed in 65.1%(54/83)and 73.5%(61/83)cases of DLBCL,respectively.The expression level of NF-κB p65 was positively correlated with mPGES-1 expression(P<0.05).The expression of these two proteins was found to be significantly associated with B cell lymphoma/leukemia-2 protein(BCL-2),higher expression of Ki67,higher lactate dehydrogenase (LDH),more extranodal lesions,advanced Ann Arbor stage and higher international prognostic index(IPI)score(P<0.05). In addition,NF-κB p65 was related with multiple myeloma oncogene 1(MUM1),pathological type(P<0.05). Both mPGES-1 and NF-κB p65 overexpression was correlated with worse overall survival(OS)while NF-κB p65 was an in-dependent prognostic factor for OS of DLBCL(P<0.05).[Conclusions]mPGES-1 and NF-κB p65 were highly expressed in DLBCL and closely linked with each other. The overexpression of mPGES-1 and NF-κB p65 was correlated with tumor progression and unfavorable prognosis in patients with DLBCL.

OBJECTIVEThe proto-oncogene c-Met was found to express on human laryngeal carcinoma Hep-2 cell line in previous research. In the present study, the author further examined whether inhibition of c-Met by RNA interference (RNAi) might inhibit biologic activity of Hep-2 cell line in vitro and proliferation using a murine laryngeal carcinoma model.

METHODSRNAi plasmid that can express small interfering RNA targeting c-Met or siRNA that did not match any known human coding mRNA(control siRNA plasmid)was designed, constructed, and transfected into Hep-2 cell line by using cationic liposome Lipofectamine2000 as transfecting agent. In vitro, the transfection efficacy was tested by RT-PCR and Western Blot method, then elected the most inhibitive c-Met-siRNA sequence. Cell proliferation, movement and invasion were studied using MTT, cell migration assay and cell invasion assay, respectively. The Hep-2 cells were transplanted into nude mice, then the time of tumor formation and growth were observed. After tumor formation, c-Met-siRNA was given as the anti-tumor therapy. Expression of c-Met, MMP-9 and VEGF were detected by Western Blot method.

RESULTSAfter the pSilencer2.0/c-Met-shRNA recombinant plasmid transfection into laryngeal carcinoma Hep-2 cells, the expression of mRNA and protein of c-Met decreased significantly in Hep-2 cells. On the 35th day after tumor vaccination, the tumor volume was (138 ± 27) mm³ in c-Met-siRNA transfection group, Which was diminished significantly in contrast with control group (P < 0.01). The expression of c-Met, MMP-9 and VEGF in the tumor of experiment group was decreased significantly, respectively (P < 0.05).

CONCLUSIONSThe results indicated that c-Met-siRNA can down-regulate the expression of c-Met and markedly inhibit laryngeal carcinoma Hep-2 cell proliferation, movement and invasion and the growth of transplantation tumor of nude mice. The siRNA expressing plasmid mediated gene therapy might be a new strategy in targeting molecular therapy of cancer of larynx.

S-phase kinase-associated protein 2 (Skp2), which plays a role in cell cycle regulation, is commonly overexpressed in a variety of human cancers and associated with poor prognosis. However, its role in nasopharyngeal carcinoma (NPC) is not well understood. In this study, we examined the clinical significance of Skp2, with a particular emphasis on overall survival (OS) and disease-free survival (DFS), in NPC cases in South China, where NPC is an epidemic. Additionally, we explored the function of Skp2 in maintaining a cancer stem cell-like phenotype in NPC cell lines. Skp2 expression was assessed for 127 NPC patients using tissue microarrays and immunohistochemistry and analyzed together with clinicopathologic features, OS, and DFS. Skp2 expression was detectable, or positive, in 75.6% of patients. Although there was no correlation between Skp2 and any clinicopathologic factor, Skp2 expression significantly portended inferior OS (P = 0.013) and DFS (P = 0.012). In the multivariate model, Skp2 expression remained significantly predictive of poor OS [P = 0.009, risk ratio (RR) = 4.06] and DFS (P = 0.008, RR = 3.56), and this was also true for clinical stage (P = 0.012 and RR=3.201 for OS; P = 0.002 and RR=1.94 for DFS) and sex (P = 0.016 and RR=0.31 for OS; P = 0.006 and RR = 0.27 for DFS). After Skp2 knockdown, a colony formation assay was used to evaluate the self-renewal property of stem-like cells in the NPC cell lines CNE-1 and CNE-2. The colony formation efficiency in CNE-1 and CNE-2 cells was decreased. In Skp2-transfected CNE-1 and CNE-2 cells, side population (SP) proportion was increased as detected by flow cytometry. Skp2 is an independent prognostic marker for OS and DFS in NPC. Skp2 may play a role in maintaining the cancer stem cell-like phenotype of NPC cell lines.

The UPLC-MS/MS was established for the determination of acetyl-11-keto-beta-boswellic acid(AKBA) and β-boswellic acid(β-BA), the main active components of Olibanum and Myrrha extracts in Xihuang Formula, in rat plasma and urine. The effects of compatibility on the pharmacokinetic behaviors of AKBA and β-BA in rats were investigated, and the differences in pharmacokinetic behaviors between healthy rats and rats with precancerous lesions of breast cancer were compared. The results showed that compared with RM-NH and RM-SH groups, the AUC_(0-t) and AUC_(0-∞) of β-BA increased(P<0.05 or P<0.01), T_(max) decreased(P<0.05 or P<0.01), and C_(max) increased(P<0.01) after compatibility. The trends of AKBA and β-BA were the same. Compared with RM-SH group, the T_(max) decreased(P<0.05), C_(max) increased(P<0.01), and the absorption rate increased in the normal group of Xihuang Formula. The results of urinary excretion showed that there was a decreasing trend in the urinary excretion rate and total urinary excretion of β-BA and AKBA after compatibility, but there was no statistical difference. Compared with normal group of Xihuang Formula, the AUC_(0-t) and AUC_(0-∞) of β-BA increased(P<0.05), T_(max) increased(P<0.05), and the clearance rate decreased in the breast precancerous lesion group. AUC_(0-t) and AUC_(0-∞) of AKBA showed an increasing trend, the in vivo retention time was prolonged, and the clearance rate was reduced, but there was no significant difference compared with the normal group. The cumulative urinary excretion and urinary excretion rate of β-BA and AKBA decreased under pathological conditions, indicating that pathological conditions could affect the in vivo process of β-BA and AKBA, and reduce their excretion in the form of prototype drugs, showing different pharmacokine-tic characteristics from normal physiological conditions. In this study, UPLC-MS/MS analysis method was established, which was sui-table for in vivo pharmacokinetic analysis of β-BA and AKBA. This study laid a foundation for the development of new dosage forms of Xihuang Formula.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
