According to the lastest statistics, the overall morbidity and mortality of cancer in China still show an upward trend compared with historical data. An in-depth understanding of the molecular mechanisms of tumorigenesis and development is important to formulate future treatment strategies. Interleukin 11 (IL-11) is a member of cytokines that traditionally promote megakaryocyte maturation and regulate immune activity. In recent years, the promoting effect of IL-11 on tumor has been gradually discovered. This review mainly expounds that IL-11 is regu-lated by transforming growth factor-β/drosophila mothers against decapentaplegic protein (TGF-β/Smad) pathway, and may play a role in tumor-igenesis, drug resistance, metastasis and tumor microenvironment through signal transduction pathways such as Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway and phosphatidylinositol 3 kinase/protein kinase B (PI3K/AKT) pathway, and explores the application prospect of interfering IL-11 signal transduction in tumor therapy.

Objective To investigate the opportunity of non-bladder perfusion after transurethral enucleation and resection of prostate (TUERP).Methods Sixty patients suffered from TUERP were divided into two groups according to random number with 30 patients in each group.The observation group was halted bladder perfusion on the next day of operation,and the control group was halted after 3 d.The ambulation time,the rates of urinary tract infection and contraction of bladder and quality of life were recorded and analyzed.Results Contraction of bladder in 1 case and no urinary tract infection happened in the observation group and 9 cases and 10 cases in the control group respectively; the differences between the two groups were significant ( x2 =7.680,12.000,respectively ; P ＜ 0.05 ).Score of QOL one month later in the observation group was (0.75 ± 0.15 ) and ( 1.50 ± 0.31 ) in the control group,and the difference was significant ( t =- 11.995,P ＜0.01 ).Conclusions The halted bladder perfusion in the next day after operation can decrease ambulation time,decrease the rates of urinary tract infection and contraction of bladder and improve quality of life.

OBJECTIVETo investigate the prevalence of chronic kidney disease (CKD) in subjects with different glucose metabolism status.

METHODSBetween January, 2015 and October, 2015, a total of 934 subjects without a previous diagnosis of diabetes visiting the Department of Endocrinology or Health Examination Center underwent oral glucose tolerance test (OGTT), which identified 266 subjects with normal glucose tolerance (NGT group), 243 pre-diabetic subjects, and 425 patients with diabetes mellitus group. The baseline characteristics and laboratory test data of the subjects were collected. The diagnosis of CKD was established for an eGFR <60 mL/min/1.73 m(2) or a ACR≥30 mg/g, and the prevalence of CKD were compared among the 3 groups. Logistic regression model was used to analyze the OR value of the risk factors of CKD.

RESULTSThe prevalences of CKD in NGT, pre-diabetic and diabetic groups were 10.2%, 26.3% and 32.5%, respectively. Pairwise comparisons showed that the prevalence of CKD was significantly higher in pre-diabetic group (P<0.001, OR=3.17, 95% CI 1.94-5.17) and diabetic group (P<0.001, OR=4.27, 95% CI 2.72-6.65) than in NGT group, and was comparable between the pre-diabetic and diabetic groups (P=0.115, OR=1.35, 95% CI 0.95-1.91). Logistic regression analysis, after adjustment for age, gender, blood pressure, hypertension, blood lipids and uric acid, showed that pre-diabetes (OR=2.03, P=0.044) and diabetes mellitus (OR=2.22, P=0.016) were independently associated with CKD.

CONCLUSIONGlucose metabolism status has a significant independent impact on the incidence of CKD, suggesting the importance of early detection of pre-diabetes and timely interventions in pre-diabetic subjects in prevention CKD.

Objective Factor V Leiden(FvL)causing activated protein C resistance is a genetic risk factor for venous thrombosis in humans,and it's effect on atherosclemsis is controversial.We evaluated the effect of FvL mutation on atherosclerosis in apolipoprotein E deftcient mice fed with normal diet.Methods Degree of atherosclerosis and tissue fibrin deposition were determined in Fv+/+ApoE-/-,FvQ/ApoE-/-and FvQ/QApoE-/-mice.Results In the presence of ApoE deficiency.homozygous FvL significandy increased atherosclerosis coverage in ApoE-/-mice(FvQ/QApoE-/-vs.Fv+/+ApoE-/-=5.0%±1.1%vs.2.2%±0.4%,P＜0.005)and tissue fibrin deposition in atherosclerotic lesion(FvQ/QApoE-/-vs.Fv+/ApoE-/-=3.4%±0.5%vs.1.8%±0.4%,P＜0.05).The atherosclerotic Iesion of FvQ/+ApoE-/-mice was intermediate between FvQ/Q ApoE -/-and Fv+/ApoE-/-,and there was no significant difference comparing with any of them.Condusions Therie observations demonstrate that homozygous FvL could promote atherosclerosis and fibrin deposition in apolipoprotein E deficient mice suggesting that Factor V mutation could be an important genetic risk factor for the enhanced atherosclerosis in human.

OBJECTIVETo investigate the levels of blood pressure and serum lipids, and examine the relationship between hypertension and hyperlipidemia in Hei Yi Zhuang Chinese living in Guangxi.

METHODSA total of 1056 people of Hei Yi Zhuang ethnicity were studied. Blood pressure, body height, body weight, and serum levels of lipids and apolipoprotein were measured. The data were compared with those in 925 people of Han ethnicity, who live in the same region.

RESULTSSystolic blood pressure and pulse pressure were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of isolated systolic hypertension and hypertension was also significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). Serum concentrations of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and apolipoprotein (Apo) B, and the prevalence of hypercholesterolemia and hyperlipidemia were significantly lower in Hei Yi Zhuang than Han Chinese (P < 0.05). Serum concentrations of high-density lipoprotein cholesterol and the Apo A1 to Apo B ratio were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of hypertension in Hei Yi Zhuang Chinese was positively associated with triglycerides (r = 0.425, P < 0.05), whereas the prevalence of hypertension in Han Chinese was positively correlated with total cholesterol (r = 0.623, P < 0.001).

OBJECTIVETo establish and characterize a novel human myeloid leukemia cell line SH-2.

METHODSBone marrow mononuclear cells (BMMNC) isolated from a AML-M2 patient, who failed to obtain complete remission after chemotherapy and allogenic bone marrow transplantation were passed in a long term IMDM culture medium supplemented with 20% fetal calf serum. Stromal cells were retained and rh-IL-3 was added in the culture system. A new human myeloid leukemia cell line SH-2 was successfully established with a cytogenetic characteristics of a loss of Y chromosome (-Y), a derivative chromosome 16 resulting from unbalanced translocation between chromosome 16 and 17, monosome 17, trisomy 19 and p53 alteration. Various methods were employed to characterize SH-2 cell line.

RESULTSSH-2 cells has been maintained without cytokine and stromal cells for more than 3 years without EB virus and mycoplasma contamination. SH-2 cells had the basically same morphological, immunophenotypic and cytogenetic features as the patient's leukemia cells did, such as myeloid morphology, an immunophenotype of CD13+, CD33+, CD56+, CD16/56+ and a hypodiploid karyotype of 45, X, -Y, der(16)t(16;17)(q24;ql2), -17, +19, which were gradually decreased and replaced by the near-tetraploid cells with a karyotype of 73-102(80), XX, -Y, -Y, del (q131)x2, der(16)t(16;17)(q24;q12)x2, -17, -17, +19, +19. FISH and multiple FISH delineated all the abnormalities and revealed a loss of one p53 allele due to monosomy 17. DNA direct sequencing detected a point mutation of CAG to CAT at codon 576 of exon 5 in another p53 allele. RT-PCR showed that SH-2 cells expressed apoptosis-related genes (bcl-2, Fas, GST-pi and p2) rather than MDR-related genes. Short tandem repeat PCR provided powerful evidence for the derivation of SH-2 cell line from the patient's leukemia cells. SH-2 cells had certain colony formation and tumorigenic capacities in nude and SCID mice.

CONCLUSIONSH-2 is a new myeloid leukemia cell line with a unique biology background, and will provide a useful tool for leukemia research.

Hepatotoxicity induced by bioactive constituents in traditional Chinese medicines or herbs,such as bavachin(BV)in Fructus Psoraleae,has a prolonged latency to overt drug-induced liver injury in the clinic.Several studies have described BV-induced liver damage and underlying toxicity mechanisms,but little attention has been paid to the deciphering of organisms or cellular responses to BV at no-observed-adverse-effect level,and the underlying molecular mechanisms and specific indicators are also lacking during the asymptomatic phase,making it much harder for early recognition of hepatotoxicity.Here,we treated mice with BV for 7 days and did not detect any abnormalities in biochemical tests,but found subtle steatosis in BV-treated hepatocytes.We then profiled the gene expression of hepatocytes and non-parenchymal cells at single-cell resolution and discovered three types of hepatocyte subsets in the BV-treated liver.Among these,the hepa3 subtype suffered from a vast alteration in lipid metabolism,which was characterized by enhanced expression of apolipoproteins,carboxylesterases,and stearoyl-CoA desaturase 1(Scd1).In particular,increased Scd1 promoted monounsaturated fatty acids(MUFAs)syn-thesis and was considered to be related to BV-induced steatosis and polyunsaturated fatty acids(PUFAs)generation,which participates in the initiation of ferroptosis.Additionally,we demonstrated that mul-tiple intrinsic transcription factors,including Srebf1 and Hnf4a,and extrinsic signals from niche cells may regulate the above-mentioned molecular events in BV-treated hepatocytes.Collectively,our study deciphered the features of hepatocytes in response to BV insult,decoded the underlying molecular mechanisms,and suggested that Scd1 could be a hub molecule for the prediction of hepatotoxicity at an early stage.

Objective: To explore the current situation of fetal heart defects in Yunnan Province and surrounding high altitude areas and the social factors affecting pregnancy outcome. Methods: This is a retrospective study. Pregnant woman who underwent fetal echocardiography and diagnosed as fetal cardiac defects in Yunnan Fuwai Cardiovascular Hospital from June 2017 to January 2021 were included. According to the clinical prognostic risk scoring system and grading criteria of fetal cardiac birth defects, the cases were divided into grade Ⅰ to Ⅳ. The disease distribution and proportion of each prognostic grade, pregnancy outcomes were analyzed and compared. The cases were divided into continued pregnancy group and terminated pregnancy group according to pregnancy outcome. The social factors that may affect the selection of pregnancy outcomes were analyzed by multivariate logistic regression analysis. Results: A total of 4 929 fetal echocardiography examination data were collected, and 4 464 cases (90.57%) were from Yunnan Province and surrounding high altitude areas. 2 166 cases of heart defects were finally analyzed, including 998 cases of congenital heart disease (CHD), 93 cases of cardiac tumors, cardiomyopathy and arrhythmia, 1 075 cases of foramen ovale, ductus arteriosus abnormalities and normal variations. The pregnant women were (29.2±5.0) years old with (25.6±3.8) gestational weeks. The number of cases with prognostic grade from Ⅰ to Ⅳ was 1 037 (47.88%), 620 (28.62%), 314 (14.50%), and 44 (2.03%), respectively. And 151 cases (6.97%) were not classified. The cases of normal variation and thin aortic arch development accounted for 42.66% (924/2 166), 5.22% (113/2 166), respectively. The top 3 diseases of grade Ⅱ were ventricular septal defect, coarctation of aorta and mild-moderate pulmonary stenosis, respectively, and their distribution was 11.63% (252/2 166), 3.92% (85/2 166) and 2.35% (51/2 166) respectively in all cases of heart defects, and 25.25% (252/998), 8.52% (85/998) and 5.11% (51/998) respectively in cases of CHD. Among the cases rated as grade Ⅲ and Ⅳ, most of them were complicated congenital heart disease, and the disease types are scattered. The more common cases in grade Ⅲ were complete transposition of great arteries (accounting for 2.40% (52/2 166) of all cases with heart defects, 5.21% (52/998) of all cases with CHD) and pulmonary artery occlusion (type Ⅰ to Ⅲ) with ventricular septal defect (accounting for 2.17% (47/2 166) of all cases with heart defects, and 4.71% (47/998) of all cases with CHD). In grade Ⅳ, single ventricle (0.74% (16/2 166) of all cases with heart defects, 1.60% (16/998) of all cases with CHD) and left ventricular dysplasia syndrome (0.65% (14/2 166) of all cases with heart defects, 1.40% (14/998) of all cases with CHD) are more common. A total of 1 084 cases were successfully followed up, and 675 cases were born, 392 cases were terminated, spontaneous abortion occurred in 17 cases. The proportion of terminated pregnancy cases was significantly increased from grade Ⅰ to Ⅳ, accounting for 5.24% (21/401), 27.78% (70/252), 89.54% (214/239) and 95.56% (43/45), respectively. Among the terminated pregnancy cases, those with grade Ⅲ accounted for the highest proportion (54.59% (214/392)). The distribution of terminated pregnancy cases was mainly complex congenital malformations or diseases with very poor prognosis (pregnancy outcome grade Ⅲ and Ⅳ), and proportion of terminated pregnancy with pregnancy outcome grade Ⅰ and Ⅱ cases (normal variation or good prognosis) accounted for 5.36% (21/392) and 17.86% (70/392), respectively. The results of multivariate logistic regression analysis showed that pregnant women with low education (high school and below: OR=2.73, 95%CI 1.26-5.93, P<0.001; illiteracy: OR=3.27, 95%CI 1.29-7.10, P<0.001) and low family income (Annual income<100 000 yuan: OR=2.47, 95%CI 1.69-5.12, P<0.001) were more likely to choose termination of pregnancy in case of fetal heart defect. Conclusion: In Yunnan province and the surrounding high altitude areas, the disease distribution of fetal heart defect is mainly simple or low-risk disease, but the complex malformation, especially the disease with poor pregnancy outcome, accounts for a relative high proportion. Pregnancy termination also occurs in some cases with good pregnancy outcome. The education level and family income of pregnant women may affect their choice of pregnancy outcome in case of fetal heart defect.
