OBJECTIVETo construct and express human CD96 gene outer membrane domain (hCD96om) in prokaryotic cells and prepare rabbit polyclonal antibody of hCD96om.

METHODShCD96om was amplified by RT-PCR from the peripheral blood of patients with acute myeloid leukemia and inserted into prokaryotic expression vector pET32a(+) to construct the recombinant plasmid pET32-CD96. The expression of hCD96om was induced by IPTG in BL21(DE3) cells, and the expression product was identified by Western blotting. The anti-hCD96 polyclonal antibody was prepared by immunization of rabbits with the fusion protein. The specificity of anti-hCD96 antibody was determined by Western blotting.

RESULTShCD96om protein was expressed in E.coli BL21(DE3) cells in the form of inclusion body, with a relative molecular mass around 37 kD. Western blotting showed a specific reaction of the prepared antiserum with the 70 kD protein extracted from human leukemia cell line HL-60 cells and with the 37 kD hCD96om fusion protein.

CONCLUSIONThe CD96 gene of human has been successfully cloned and expressed in BL21(DE3) cells, and its rabbit polyclonal antibody has been obtained.

OBJECTIVEThe aim of this study was to evaluate the correlation of protein expressions of CXC chemokine receptor 4 (CXCR4), vascular endothelial growth factor-C (VEGF-C) and cytokeratin 19 (CK-19) with lymph node metastasis (LNM) in patients with hepatocellular carcinoma (HCC), and their survival.

METHODSThe expressions of CXCR4, VEGF-C and CK-19 in HCC patients with (n = 123) or without (n = 145) LNM were determined using tissue microarray and immunohistochemical staining. The relationship between clinicopathological features and CXCR4, VEGF-C and CK-19 were analyzed. Evaluation of immunostaining was performed semiquantitatively by visual assessment.

RESULTSThe UICC T stage, and expressions of nuclear CXCR4, VEGF-C and CK-19 were independent risk factors for LNM. Nuclear CXCR4, VEGF-C and CK-19 expression were predictive factors for LNM in HCC patients. In patients with LNM, the median survival time was 15.1 months for patients with high nuclear CXCR4 expression and 24.5 months for those with low nuclear CXCR4 expression. The median survival time was 15.1 months for patients with high tumor VEGF-C expression and 31.1 months for those with low tumor VEGF-C expression. The median survival time was 12.0 months for patients with positive CK-19 expression and 19.2 months for patients with negative CK-19 expression. Patients with high nuclear CXCR4, VEGF-C or CK-19 expression had significantly poorer prognosis than those with low expression (all P < 0.05). PVT, UICC T stage and expressions of nuclear CXCR4, VEGF-C, and CK-19 were independent prognostic factors.

CONCLUSIONIncreased protein expressions of nuclear CXCR4, VEGF-C, and CK-19 are independent risk factors for developing lymph node metastasis, and they are significantly correlated with LNM and poor outcome in HCC patients.

OBJECTIVETo investigate the effects of hypertonic sodium chloride hydroxyethyl starch 40 (HSH) on brain edema and morphological changes during whole body hyperthermia (WBH) in rats.

METHODSSixty adult male SD rats were randomized into control group, WBH group without fluid infusion (group HT), WBH group with Ringer's infusion (group RL), WBH group with HAES + Ringer's infusion (group HRL) and WBH group with HSH infusion (group HSH). WBH was induced by exposure to 36 degrees celsius; for 3 h to achieve a rectal temperature of 41-42 degrees celsius;, and the corresponding fluids were administered intravenously within 30 min at the beginning of WBH. The control rats were housed at a controlled room temperature (22∓1) degrees celsius; for 4 h. After cooling at room temperature for 1 h, the rats were sacrificed and brain water content and morphological changes were evaluated.

RESULTSCompared with the control group, all the WBH groups had significantly increased brain water content (P<0.05 or 0.01), but group HSH showed a significantly lower brain water content than group HT (P<0.05). The rats in groups HT, RL and HRL showed serious to moderate structural changes of the brain tissue and nerve cells, but HSH group had only mild pathologies.

CONCLUSIONHSH can reduce brain edema and ameliorate the damages to brain cells in rats exposed to WBH.

OBJECTIVETo study the relationship between metastasis or recurrence of hepatocellular carcinoma (HCC) and hepatitis B virus (HBV) DNA load or the presence of double mutation at 1762/1764 in the basic core promoter (BCP).

METHODSOne-hundred-and-fifty-seven patients with HCC were included in the study. Events of tumor metastasis or recurrence were recorded during 120 weeks of clinical follow-up after treatment by surgery or transarterial chemoembolization (TACE). The 1-year follow-up included monthly alpha fetoprotein (AFP) measurement and abdominal ultrasonography (US), as well as helical computed tomographic (CT) scan performed every 3 months. Follow-up beyond 1-year (surveillance) included AFP measurement and abdominal US every 2 months and helical CT scan every 6 months. Suspected metastasis or recurrence was investigated by hepatic angiography and confirmed according to the combined imaging findings. Serum HBV DNA level was measured by real-time PCR. HBV genotypes were determined by PCR-restriction fragment length polymorphism analysis.

RESULTSOf the 157 HCC cases 110 experienced tumor metastasis or recurrence; the cumulative probability of post-treatment HCC metastasis or recurrence was 4 (2.55%) at week 12, 14 (8.92%) at week 24, 28 (17.83%) at week 48, 64 (40.76%) at week 72, 92 (58.60%) at week 96, and 110 (70.06%) at week 120. Multivariate analysis indicated that both the BCP 1762/1764 double mutations and HBV DNA levels were risk factors for HCC recurrence or metastasis. In particular, the incidence of HCC recurrence or metastasis increased with baseline serum HBV DNA levels in a dose-response manner, ranging from 8/19 (42.1%) for less than 3 log10 copies/ml HBV DNA to 35/61 (57.3%) for 3-5 log10 copies/ml and 67/77 (87.0%) for more than 5 log10 copies/ml. After adjusting for potential confounders, serum HBV DNA level remained independently associated with HCC metastasis or recurrence. HCC recurrence or metastasis occurred in 22/43 (51.2%) of patients without BCP 1762/1764 mutations and 88/114 (77.2%) of patients with BCP 1762/1764 mutations. The adjusted odds ratio for patients infected with BCP 1762/1764 double mutation HBV, compared with those infected with non-BCP 1762/1764 mutation HBV, was 5.264 (95% CI: 1.436-12.574, P less than 0.05).

CONCLUSIONInfection with HBV carrying the BCP 1762/1764 double mutation and presence of high HBV DNA load are independent risk factors for developing HCC metastasis or recurrence after surgery or TACE.

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.

Background: With the publication of Sepsis-3 definition, epidemiological data based on Sepsis-3 definition from middle-income countries including China are scarce, which prohibits understanding of the disease burden of this newly defined syndrome in these settings. The purpose of this study was to describe incidence and outcome of Sepsis-3 in Yuetan sub-district of Beijing and to estimate the incidence rate of Sepsis-3 in China. Methods: The medical records of all adult residents hospitalized from July 1, 2012 to June 30, 2014 in Yuetan sub-district of Beijing were reviewed. Patients with sepsis-3 and severe sepsis/septic shock were identified. The incidence rates and mortality rate of sepsis-3 and sepsis/septic shock were calculated, incidence rates and in-hospital mortality rates were normalized to the population distribution in the 2010 National Census. Population incidence rate and case fatality rate between sexes were compared with the Z test, as the data conformed to Poisson distribution. Results: Of the 21,191 hospitalized patients, 935 patients were diagnosed with Sepsis-3, and 498 cases met severe sepsis/septic shock criteria. The crude annual incidence rate of Sepsis-3 in Yuetan sub-district was 363 cases per 100,000 population, corresponding to standardized incidence rates of 236 cases per 100,000 population per year, respectively. The overall case fatality rate of Sepsis-3 was 32.0%, the crude population mortality rates of Sepsis-3 was 116 cases per 100,000 population per year, the standardized mortality rate was 67 cases per 100,000 population per year, corresponding to a speculative extrapolation of 700,437 deaths in China. The incidence rate and mortality rate of Sepsis-3 were significantly higher in males, elderly people, and patients with more comorbidities. The 62.1% of patients with Sepsis-3 had community-acquired infections, compared with 75.3% of infected patients without Sepsis-3 (P < 0.001). The most common infection in patients with Sepsis-3 was lower respiratory tract infection. When compared with patients with Sepsis-3, patients diagnosed as severe sepsis/septic shock were more likely to have higher case fatality rate (53.4% vs. 32.0%, P < 0.001) Conclusions: This study found the standardized incidence rate of 236 cases per 100,000 person-year for Sepsis-3, which was more common in males and elderly population. This corresponded to about 2.5 million new cases of Sepsis-3 per year, resulting in more than 700,000 deaths in China.
