OBJECTIVETo find a kind of quick and effective haemostasis to decrease the mortality of severe bleeding.

METHODS18 severe bleeding patients with different cause received recombinant activated factor VIIa (rFVIIa) were analyzed retrospectively.

RESULTSOf total 18 cases with severe bleeding, 13 cases cured, 3 cases were effective, 2 cases ineffective. The total clinical effective rate is 88.89%. After using rFVIIa, the PT, APTT and fibrinogen level of 6 DIC patients returned to normal within 12 hours; 13 patients whose the amount of bleeding can be evaluated stopped bleeding quickly. The fastest onset time was 10 min.

CONCLUSIONrFVIIa can stanch severe bleeding for a variety of reasons rapidly and effectively, including coagulopathy, thrombocytopenia, and obstetric hemorrhage. Application of rFVIIa may decrease mortality, when conventional treatment is not valid.

Immunotherapy has opened a new era in cancer treatment. Drugs represented by immune checkpoint inhibitors have led to important breakthroughs in the treatment of various solid tumors, greatly improving the survival rate of cancer patients. Many types of immunotherapeutic drugs have become widely available; however, their efficacy is variable, and relatively few patients with advanced cancer experience life-altering durable survival, reflecting the complex and highly regulated nature of the immune system. The research field of cancer immunotherapy (CIT) still faces many challenges in pursuing the broader social goal of "curing cancer." Increasing attention has been paid to strengthening the understanding of the molecular or cellular drivers of resistance to immunotherapy, actively exploring more effective therapeutic targets, and developing combination therapy strategies. Here, we review the key challenges that have emerged in the era of CIT and the possible solutions or development directions to overcome these difficulties, providing relevant references for basic research and the development of modified clinical treatment regimens.

OBJECTIVETo explore the podocyte injury in patients with diabetic nephropathy (DN) and analyze its relationship with glucose regulated protein 78 (GRP78) and proteinuria.

METHODSThe clinical data of 48 patients diagnosed as DN by renal biopsy were reviewed. All patients were divided into two groups according to proteinuria (>3.5 g/d, n=31 and 3.5 g/d, n=17). The density of podocytes was illustrated by immunohistochemistry staining of Wilms tumor-1 (WT-1), and the immunofluorescence double-staining results of synaptopodin and GRP78 in podocytes were detected.

RESULTSThe podocyte dentistry of urine protein > 3.5 g/d group was significantly lower than that of urine protein>3.5 g/d group urine protein<3.5 g/d group(P=0.003), and it was negatively correlated with proteinuria (P=0.005). The expressions of synaptopodin and GRP78 in podocytes were also negatively correlated with proteinuria (P=0.004 and P=0.001).

CONCLUSIONThe podocyte injury is aggravated with increased proteinuria in DN patients, along with the decrease of the adaptive ability of endoplasmic reticulum to stress.

OBJECTIVETo understand the perception on roles of gender and decision-making regarding family affairs among married women and its impact on the utilization of perinatal care.

METHODSClustering sampling was conducted to select 1227 married women with at least a child aged from 0 to 7 years old, from Hebei, Hubei and Sichuan provinces. All women were interviewed using a uniform questionnaire during Nov.-Dec. 2004.

RESULTSThe overall proportion of women who had relatively poor perception of gender role was 65.1%. 59.3% of the women agreed that "husband's health is more important than wife's in the family" versus 39.7% of interviewed women agreed that "man is more suitable for leadership than woman". In 46.2% of the families, wife and husband shared the responsibility of decision making on family affairs. In 16.2% of the families women played a decisive role, while 67.1% of interviewed women had to get the approval of her husband when spending money on daily necessities. When there were different opinions between the couples, husband usually made the final decision in 20.5% of all the families versus 17.4% of families where wife made the final decision. In total,the proportion of women who had somehow rights on family affairs was 64.1%. The coverage rate of antenatal care was 91.0%, and 65.3% women who received antenatal care got the first antenatal visit during the first trimester and the proportion of women who had at least five antenatal visits was 39.7%. The institutional delivery was 59.3% among all the women. Perception of gender role was not a predictor for antenatal care utilization, but it was predictive of institutional delivery. Education was quite a significant predictor on perinatal care utilization.

CONCLUSIONEfforts should be strengthened to improve women's awareness and to increase their perception on gender role in the families so that more women could achieve quality perinatal care.

OBJECTIVETo study the burden of pediatric cancer in Jiangxi, China, in 2010 and 2015 and its changes from 2010 to 2015.

METHODSThe data of pediatric cancer in Jiangxi in 2010 and 2015 were collected from the Global Burden of Disease Study 2015 in China, including number of cases, number of deaths, years of life lost (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY). The standardized incidence rate, mortality rate, and DALY rate were calculated with the national census data in 2010 as the standard population, in order to evaluate the changes in incidence, mortality, and disease burden of pediatric cancer in Jiangxi.

RESULTSIn both 2010 and 2015, boys had higher numbers of cases, deaths, and DALY than girls, and the 5-14 years group had higher numbers than the 0-4 years group; boys had higher incidence rate, mortality rate, and DALY rate than girls, and the 0-4 years group had higher rates than the 5-14 years group. In 2015, the standardized incidence rate of pediatric cancer was reduced by 6.66% in the 0-4 years group and 17.56% in the 5-14 years group; the standardized mortality rate was reduced by 11.34% in the 0-4 years group and 21.78% in the 5-14 years group; the standardized DALY rate was reduced by 11.27% in the 0-4 years group and 21.67% in the 5-14 years group. Among the different types of pediatric cancer, leukemia had the highest standardized DALY rate in 2010 and 2015, followed by brain cancer and non-Hodgkin's lymphoma.

CONCLUSIONSThere was a certain reduction in the burden of pediatric cancer in Jiangxi from 2010 to 2015. Leukemia, brain cancer, and non-Hodgkin's lymphoma are the focus of prevention and treatment, and children aged less than 5 years and boys should be closely monitored.

BACKGROUNDNeuroimaging studies have found that functional changes exist in patients with Parkinson's disease (PD). However, the majority of functional magnetic resonance imaging (fMRI) studies in patients with PD are task-related and cross-sectional. This study investigated the functional changes observed in patients with PD, at both baseline and after 2 years, using resting-state fMRI. It further investigated the relationship between whole-brain spontaneous neural activity of patients with PD and their clinical characteristics.

METHODSSeventeen patients with PD underwent an MRI procedure at both baseline and after 2 years using resting-state fMRI that was derived from the same 3T MRI. In addition, 20 age- and sex-matched, healthy controls were examined using resting-state fMRI. The fractional amplitude of low-frequency fluctuation (fALFF) approach was used to analyze the fMRI data. Nonlinear registration was used to model within-subject changes over the scanning interval, as well as changes between the patients with PD and the healthy controls. A correlative analysis between the fALFF values and clinical characteristics was performed in the regions showing fALFF differences.

RESULTSCompared to the control subjects, the patients with PD showed increased fALFF values in the left inferior temporal gyrus, right inferior parietal lobule (IPL) and right middle frontal gyrus. Compared to the baseline in the 2 years follow-up, the patients with PD presented with increased fALFF values in the right middle temporal gyrus and right middle occipital gyrus while also having decreased fALFF values in the right cerebellum, right thalamus, right striatum, left superior parietal lobule, left IPL, left precentral gyrus, and left postcentral gyrus (P < 0.01, after correction with AlphaSim). In addition, the fALFF values in the right cerebellum were positively correlated with the Unified PD Rating Scale (UPDRS) motor scores (r = 0.51, P < 0.05, uncorrected) and the change in the UPDRS motor score (r = 0.61, P < 0.05, uncorrected).

CONCLUSIONSThe baseline and longitudinal changes of the fALFF values in our study suggest that dysfunction in the brain may affect the regions related to cortico-striato-pallido-thalamic loops and cerebello-thalamo-cortical loops as the disease progresses and that alterations to the spontaneous neural activity of the cerebellum may also play an important role in the disease's progression in patients with PD.

OBJECTIVETo investigate the interferon alpha regulation mechanisms by screening binding proteins of interferon alpha promoter by phage display.

METHODSPCR product of interferon-alpha promoter was incubated with a phage display cDNA library that expressed a library of human liver proteins on the surface of bacteriophage T7. Unbound phages were washed off and the phages bound to the interferon alpha promoter were amplified. Positive plaques were amplified by PCR and cloned into a pGEM-Teasy vector in order to perform DNA sequence analysis and subsequent computer blasting analysis.

RESULTSPositive phage-displayed proteins binding with interferon alpha promoter were enriched after five rounds of biopanning. We found that the following proteins were relevant to interferon alpha: mitochondrial ribosomal protein, chromosome clone, fibrinogen A alpha polypeptide, enoyl coenzyme A hydratase short chain, eukaryotic translation elongation factor 1 alpha, PI-3-kinase-related kinase SMG-1-like, xeroderma pigmentosum C group, and Homo sapien activity-dependent neuroprotector (ADNP).

CONCLUSIONMany proteins with different functions could bind with interferon alpha promoter.
