Objective To investigates the gene expression of telomerase by real-time quantitative telomeric-repeat amplification protocol assay (RTQ-TRAP) in the peripheral blood mononuclear cells (PBMC) of colorectal carcinoma patients and the relationship between the telomerase gene expression in PBMC and clinicopathological features. Methods Peripheral blood samptes were collected from 71 colorectal carcinoma patients, 20 benign colorectal disease patients and 25 normal controls. The telomerase gene expression in PBMC was measured by RTQ-TRAP, and serum CEA in colorectal carcinoma patients was measured by chemiluminescence immunoassay. Results The gene expression of telomerase in PBMC was positive in 50 out of 71 cancer patients (70. 4% ) , 1 out of benign patients (5. 0% ), respectively. The difference of the telomerase gene expression of PBMC in benign colorectal diseases and cancer patients was significant (χ2 = 24. 521, P < 0. 001 ). There was no significant association between the expression of telomerase and patient's gender, age, Dukes stage, and tumor site. The positive rate of CEA in colorectal carcinoma patients was not significantly higher than positive rate of telomerase gene expression(χ2 = 2. 286,P = 0. 125). Conclusions The RTQ-TRAP method is highly accurate and sensitive in measuring telomerase gene expression. The detection of telomerase gene expression in PBMC of colorectal carcinoma patients is a simple and useful molecular marker for the diagnosis of colorectal carcinoma.

Background and purpose:Nab-paclitaxel (Abraxane) is an albumin-bound form of paclitaxel that utilizes the natural properties of albumin to improve paclitaxel delivery to the tumor. It has recently been approved for treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within short time after adjuvant chemotherapy. The purpose of this study was to evaluate the efifcacy and safety of albumin-bound paclitaxel in patients with aggressive and refractory metastatic breast cancer (MBC).Methods:A total of 58 patients with MBC were enrolled into this study from Jul. 2009 to Jan. 2014. All patients received albumin-bound paclitaxel-based chemotherapy. The adverse reactions were evaluated every cycle, and the short-term response was evaluated every two cycles. The patients were followed-up, and the survival was analyzed.Results:58 patients with refractory MBC were evaluable for response, 67.2% of patients received multiple line (≥3 lines) chemotherapy, 32.8% of patients with first and second line of chemotherapy were involved metastasis within one year after adjuvant chemotherapy, 84.5% of patients with visceral metastasis and 93.1% with prior taxane treatment. The objective response rate (ORR) was 13.8%, and disease control rate (DCR) was 60.3%, the median progression free survival (PFS) was 4.0 months, and the overall survival (OS) was 10.1 months. For 23 patients with triple negative breast cancer, ORR was 13.0% and DCR was 56.5%, the median PFS was 4.1 months, and OS was 6.6 months. The main toxicity was myelosuppression (grades 3 and 4 neutropenia, anemia and thombocytopenia were seen in 34.5%, 12.1% and 6.9% of patients, respectively), gastrointestinal reactions, sensory neuropathy, myodynia/arthragia, fatigue, alopecia and so on.Conclusion:The albumin-bound paclitaxel-based chemotherapy can be used in aggressive and refractory MBC. It also showed antitumor activity in taxanes-resistance patients and triple negative patients with good safety and tolerance.

Objective:To detect the proportion of lymphocyte subsets in peripheral blood of the ad-vanced breast cancer patients before and after chemotherapy with docetaxel and thiotepa,as well as the association between the proportion of peripheral blood lymphocyte subsets with the response rate and prog-nosis.Methods:The proportions of lymphocyte subsets (CD3 +T cell,CD3 +/CD4 +T cell,CD3 +/CD8 +T cell,CD3 -/CD16 +56 +NK cell,CD3 +/CD16 +56 +T cell,CD19 +B cell,CD4 +/CD25 +T cell,CD8 +/CD28 -T cell,CD8 +/CD28 +T cell)in the peripheral blood of 86 patients were analyzed with flowcytometry before and after chemotherapy.The result was analyzed in combination with clinico-pathological data.Results:The proportion of regulatory T cells (Treg)after chemotherapy in the disease control patients decreased significantly compared with that of the progressive patients (P=0.034).The difference of the proportions of Treg before and after chemotherapy affected significantly the overall survi-val (OS).The OS of the patients with decreased proportion of Treg was significantly longer than that of the patients with increased proportion of Treg,which was 23.5 and 9.4 months respectively (P<0.05). Conclusion:The patients with decreased proportion of Treg after chemotherapy had higher response rate and better survival benefit.

Objective To explore the MRI features of acute optic neuritis with positive aquaporin?4 (AQP4) antibodies and myelin oligodendrocyte glycoprotein (MOG) antibodies during the first attack. Methods Eighty five patients (105 affected nerves) with first?episode AQP4?seropositive optic neuritis (AQP4?ON; n=58; 64 affected nerves) and MOG?seropositive optic neuritis (MOG?ON; n=27; 41 affected nerves) diagnosed by our hospital Neuro?ophthalmology Department between April 2014 and December 2017 were retrospectively analyzed. Double seronegative patients or double seropositive patients were not included. All patients underwent orbital conventional MRI; 29 patients also underwent RESOLVE?DWI and 55 underwent brain T2 fluid?attenuated inversion recovery (T2FLAIR). Theclinical features (age, gender, disease duration) and MRI features (T2WI, bilateral involvement, the degree and extent of enhancement, the extent of involvement, the affected segment and ADC values of nerve; demyelinating lesions of brain) were analyzed by 2 doctors. The qualitative parameters were compared with χ2 test or Fisher exact test and the quantitative parameters were compared with two independent sample t test (normal distribution) or the Mann?Whitney U test (skewed distribution). The Kappa test was used to test the consistency of the qualitative characteristics of the images evaluated by the 2 doctors. The interclass correlation coefficient (ICC) was used to test the consistency of the ADC obtained by the 2 doctors. Results There were no significant differences in the distributions of age and disease duration between 2 groups (t=1.911, Z=-1.054, P>0.05). AQP4?ON had a higher female proportion (χ2=13.911, P<0.05) and showed mainly unilateral involvement. MOG?ON more commonly showed bilateral involvement (χ2=17.640, P<0.05), but there were no significant differences in the demyelinating lesions of brain (χ2=0.000)and the presence/absence of optic tract involvement (both P>0.05). There was a higher probability of optic nerve swelling, long segmental lesions and optic nerve head involvement in MOG?ON(χ2=16.845, 13.525, 13.264, P<0.05). Moreover, the rate of obvious enhancement and the involvement of optic chiasm was higher in AQP4?ON(χ2=7.152, 5.088, P<0.05). RESOLVE?DWI showed the ADC values of the AQP4?ON were significantly lower than those of MOG?ON (t=-3.300, P<0.05). The qualitative features of image evaluated by the 2 doctors were consistent well (Kappa=0.712-0.932, P<0.001).The ADC values obtained by the 2 doctors were consistent well (ICC=0.942, P<0.001).Conclusions For the first?episode acute optic neuritis, AQP4?ON hasobvious female predilection and the trend of unilateral involvement and obvious enhancement, while MOG?ON isoften involved bilaterally with longitudinally extensive lesions. The ADC values of the AQP4?ON are significantly lower than those of MOG?ON and AQP4?ON are more vulnerable to involve the optic chiasm. Conventional MRI and RESOLVE?DWI are helpful for differentiating AQP4?ON from MOG?ON during the early stage of the disease course.

Objective:To analyze the heritability of coronary heart disease (CHD) among the Chinese twin adults.Methods:A total of 20 477 same-sex twin pairs aged 25 years and older from the Chinese National Twin Registry were interviewed. Structure equation model was used to estimate the heritability of CHD.Results:After adjusting for age and gender, the overall heritability of CHD was 0.75(0.68-0.81). Stratified analyses showed that genetic factors play a more important role in CHD incidence in ≥40 years or female twins. While the development of CHD was mainly influenced by environmental factors in 25-39 years or male twins.Conclusion:CHD is influenced by both genetic and environmental factors and the heritability is high.

Objective:To explore the genetic and environmental effects on alcohol intake.Methods:Data on 9 231 pairs of adult twins of the same sex was collected from the Chinese National Twin Registry (CNTR), between 2015 and 2018 and used in this study. Structural equation model was used to estimate the effects of genetic and environmental factors on alcohol intake.Results:A total of 9 231 pairs of twins were included in the analysis, of which 6 085 pairs were monozygotic (MZ). The average age of MZ was (36.91±13.07) years old, and males accounted for 56.80 %. The average age of dizygotic twins (DZ) was (35.22±12.48) years old, and males accounted for 55.91 %. There were 350 pairs of alcohol-drinking twins were with high-risk, accounting for 1.90 % and another 367 pairs (1.99 %) were with medium-risk. Alcohol-drinkers with medium-risk were affected by additive genetics, common and unique environmental factors, seen among the twins. The overall heritability appeared as 24.3 % (95 %CI: 0 to 56.8 %). Furthermore, 50.7 % of the variation (95 %CI: 20.4 %-79.0 %) could be explained by the common environmental factors and 24.9 % (95 %CI: 18.3 %-36.5 %) by unique environmental factors. High-risk related drinking behavior was affected by both common and unique environmental factors. The common environmental component appeared as 75.6 % (95 %CI: 69.6 %-80.8 %) and unique environmental component as 24.4 % (95 %CI: 19.2 %-30.4 %), respectively. Gender difference was seen in the heritability of those with medium or high-risk drinking behaviors. The heritability of men was 30.8 % (95 %CI: 9.8 %-53.5 %), while in women it was mainly affected by the environment. Conclusion:Both alcohol drinkers with medium and high-risk drinking behaviors were mainly affected by the environment factors and gender. With the increase of drinking volume, the effect of environment on drinking behaviors became more obvious.

Objective:To describe the differences in body mass index (BMI) distribution in adult twins registered in Chinese National Twin Registry (CNTR), and provide evidence for the risk factor analysis and prevention and control of overweight or obesity.Methods:A total of 32 725 twin pairs aged 18 years and above who completed the questionnaire survey during 2010-2018 and had complete registered information in CNTR and normal body weight and length were included in the analysis on the population and region specific distributions of BMI of twin pairs and the difference in BMI in twin pairs.Results:The twin pairs included in the analysis were aged (34.6±12.4) years, the twin pairs of same gender accounted for 79.7%. The average BMI was 22.5 kg/m 2. The overall prevalence of obesity and overweight was 4.9% and 23.7%, respectively. Participants who were men, 50-59 years old, married, had lower education level, and lived in northern China had higher overweight rate and obesity rate ( P<0.001). The difference in overweight or obesity prevalence between monozygotic (MZ) twin pars and dizygotic (DZ) twin pairs was not significant, but firstborn twin pairs had slightly higher rates of overweight and obesity than later-born twin pairs ( P<0.05). The analysis in same gender-twin pairs indicated that the difference in BMI was associated with age (trend test: P<0.001), and the difference was more obvious in DZ twin pair in MZ pair and this difference increased with age. The concordant rate of BMI was higher in MZ twin pairs than DZ twin pairs ( P<0.05). Conclusion:The distribution of BMI of twin pairs varied with population and region and BMI varied with age due to its genetic nature.
