OBJECTIVETo study the inhibition of berberine (BBR) against ECV-304 apoptosis induced by Staphylococcus aureus (S. aureus).
METHODSECV-304 cells were pre-treated with 128 microg/mL BBR for 2 h and then S. aureus was added (1:100). The viability of cells was detected by MTT (3-4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The morphological changes were observed by Hoechst 33258 staining. The protection of BBR for infected cells was detected by DNA Ladder.
RESULTSECV-304 cells' viability were not obviously affected by berberine. But S. aureus induced ECV-304 cells' viability could be significantly inhibited by pre-treatment of BBR (P < 0.05). Besides S. aureus-induced ECV-304 apoptosis could be reduced, with significantly lessened apoptotic body and unobvious DNA degradation.
CONCLUSIONBBR could significantly inhibit S. aureus induced ECV-304 apoptosis.

OBJECTIVEObese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thickness (IMT) in obese children and adolescents were measured to investigate the relationship between the dyslipidemia and early vascular lesions.
METHODA total of 580 obese children and adolescents aged from 7 to 17 years of age were enrolled from 3 hospitals from Jan. 2008 to Sept. 2009. They were divided into 2 groups according to their blood lipoid levels. Ortholiposis group included 100 males and 52 females with a mean age of 10.47 years and a mean body mass index (BMI) of 28.28 kg/m(2). Dyslipidemia group included 305 males and 123 females with a mean age of 10.83 years and a mean BMI of 27.60 kg/m(2). Physical examination, and measurement of blood lipid, glucose and liver enzyme were taken. Carotid IMT was measured for 285 subjects.
RESULT(1) Hypertension was found in 12.5% (19/152) and 20.1% (86/428) patients in ortholiposis and dyslipidemia groups, respectively, with a significant difference (χ(2) = 4.362, P = 0.037). The OR was 1.760 with 95% confidence interval of 1.030 - 3.008. Higher prevalence of hypertension was found in patients with dyslipidemia. (2) The left, right and mean common carotid IMTs of dyslipidemia group were higher than those of ortholiposis group without significant difference (all P > 0.05). The left, right and mean internal carotid IMTs in dyslipidemia group were (0.66 ± 0.15) mm, (0.65 ± 0.15) mm and (0.65 ± 0.15) mm, respectively while these in ortholiposis group were (0.62 ± 0.13) mm, (0.60 ± 0.13) mm and (0.61 ± 0.12) mm, respectively (P < 0.05 for all). (3) Bivariate correlation analysis showed that systolic blood pressure was positively correlated with age, BMI, BMI Z score, waist circumference, hip circumference, uric acid, alanine transaminase, triglyceride, fasting insulin and insulin resistance index (P < 0.05 for all). Moreover, mean carotid and internal carotid IMTs were positively correlated with age, BMI, waist circumference, hip circumference, and triglyceride (all P < 0.05). Multiple linear regression analysis showed that hip circumference and insulin resistance index were independent determinants of systolic pressure. Waist circumference was independent determinant of mean common and internal carotid IMT and triglyceride was independent determinants of mean internal carotid IMT.
CONCLUSION(1) Vascular lesions, including hypertension and thicker tunica intima are common in obese children and adolescents. (2) Vascular lesions are closely related with dyslipidemia, and waist circumference and hypertriglyceridemia are the risk factors.

BACKGROUNDBerberine is one of the main constituents of Coptidis rhizoma (CR) and Cortex phellodendri. In this study, we investigated the beneficial effects of berberine on renal function and its possible mechanisms in rats with diabetic nephropathy (DN).
METHODSMale Wistar rats were divided into three groups: normal, diabetic model, and berberine treatment groups. Rats in the diabetic model and berberine treatment groups were induced to diabetes by intraperitonal injection with streptozotocin (STZ). Glomerular area, glomerular volume, fasting blood glucose (FBG), blood urea nitrogen (BUN), serum creatinine (Cr) and urine protein for 24 hours (UP24h) were measured using commercially available kits. Meanwhile, the activity of superoxide dismutase (SOD), content of malondialdehyde (MDA) in serum, activity of aldose reductase (AR) and the expression of AR mRNA and protein in kidney were detected by different methods.
RESULTSThe results showed that oral administration of berberine (200 mg x kg(-1) x d(-1)) significantly ameliorated the ratio of kidney weight to body weight. Glomerular area, glomerular volume, FBG, BUN, Cr and UP24h were significantly decreased in the berberine treatment group compared with the diabetic model group (P < 0.05). Berberine treatment significantly increased serum SOD activity and decreased the content of MDA compared with diabetic model group (P < 0.05). AR activity as well as the expression of AR mRNA and protein in the kidney was markedly decreased in the berberine treatment group compared with diabetic model group (P < 0.05).
CONCLUSIONThese results suggested that berberine could ameliorate renal dysfunction in DN rats through controlling blood glucose, reduction of oxidative stress and inhibition of the activation of the polyol pathway.

Cancer remains a serious healthcare problem despite significant improvements in early detection and treatment approaches in the past few decades. Novel biomarkers for diagnosis and therapeutic strategies are urgently needed. In recent years, long noncoding RNAs (lncRNAs) have been reported to be aberrantly expressed in tumors and show crosstalk with key cancer-related signaling pathways. In this review, we summarized the current progress of research on cytoplasmic lncRNAs and their roles in regulating cancer signaling and tumor progression, further characterization of which may lead to effective approaches for cancer prevention and therapy.

OBJECTIVETo investigate the association between birth defects and dietary nutrient intake in a high risk area of China.
METHODSA dietary survey was performed and serum folic acid was measured in women whose pregnancy was affected by neural tube defects (NTDs) or unaffected by any birth defects (BDs) in Zhongyang and Jiaokou Counties in Shanxi Province of China.
RESULTSThe local average consumption of foods including dark green vegetables, fruits, fat and meat, and nutrient intake (e.g., energy, protein, retinol, riboflavin, vitamin E, and selenium) were lower than the national average level. In women of childbearing age, these regions, the intake of nutrients was much lower than the recommended nutrient intake (9%-77%). The case-control dietary nutrition study of women whose pregnancy was affected by BDs (including NTDs and congenital heart defects) demonstrated that, in early pregnancy, adequate nutrition (i.e., eating meat, fresh vegetables, fruit more than once a week) was a protective factor, while eating germinated potatoes was a risk factor. The geometrical mean (p5-p95) of serum folic acid in women with NTD birth defects was 9.6 nmol/L (3.6, 23.03), which was significantly lower than that in normal women (14.03 nmol/L).
CONCLUSIONWomen of childbearing age in the two counties of Shanxi Province, China, have a marked insufficient intake of some nutrients, especially folic acid, zinc, vitamins A and B12. This nutrient deficiency may be an important risk factor for the high prevalence of birth defects in these regions. Therefore, adequate dietary nutrition in early pregnancy can prevent BDs.

Purpose:
Triple-negative breast cancer (TNBC) is highly malignant and has poor prognosis and a high mortality rate. The lack of effective therapy has spurred our investigation of new targets for treating this malignant cancer. Here, we identified RON (macrophage-stimulating 1 receptor) and MET (MET proto-oncogene, receptor tyrosine kinase) as a prognostic biomarker and therapeutic targets for potential TNBC treatment.
Materials and Methods:
We analyzed RON and MET expression in 187 primary TNBC clinical samples with immunohistochemistry. We validated the targeted therapeutic effects of RON and MET in TNBC using three tyrosine kinase inhibitors (TKIs): BMS-777607, INCB28060, and tivantinib. The preclinical therapeutic efficacy of the TKIs was mainly estimated using a TNBC xenograft model.
Results:
Patients with TNBC had widespread, abnormal expression of RON and MET. There was RON overexpression, MET overexpression, and RON and MET co-overexpression in 63 (33.7%), 63 (33.7%), and 43 cases (23.0%), respectively, which had poor prognosis and short survival. In vivo, the TKI targeting RON ant MET inhibited the activation of the downstream signaling molecules, inhibited TNBC cell migration and proliferation, and increased TNBC cell apoptosis; in the xenograft model, they significantly inhibited tumor growth and shrank tumor volumes. The TKI targeting RON and Met, such as BMS-777607 and tivantinib, yielded stronger anti-tumor effects than INCB28060.
Conclusion
RON and MET co-overexpression can be significant pathological characteristics in TNBC for poor prognosis. TKIs targeting RON and MET have stronger drug development potential for treating TNBC.

Objective: To compare the outcomes between haploidentical donor hematopoietic stem cell transplantation (haplo-HSCT) and matched-sibling donor transplantation (MSD-HSCT) for paroxysmal nocturnal hemoglobinuria (PNH) . Methods: The clinical data of 40 PNH patients received HSCT (haplo-HSCT=25, MSD-HSCT=15) from July 2007 to May 2018 were analyzed retrospectively to compare the outcomes between haplo-HSCT and MSD-HSCT groups. Results: There were no differences in terms of gender, age, patients of PNH-AA and median time from diagnosis to transplantation between the 2 groups (P>0.05) . The median values of absolute mononuclear cell counts and CD34+ cells infused were 10.74 (4.80-22.86) ×108/kg and 12.19 (5.14-17.25) ×108/kg (P=0.866) , 3.57 (0.68-7.80) ×106/kg and 4.00 (3.02-8.42) ×106/kg (P=0.151) respectively, in haplo-HSCT and MSD-HSCT groups. All patients attained complete engraftment, no patient occurred graft failure. The median durations for myeloid and platelet engraftment were 12 (range, 9-26) and 11 (range, 7-15) days (P=0.065) , 19 (range, 11-75) and 13 (range, 11-25) days (P=0.027) respectively, in haplo-HSCT and MSD-HSCT groups. During a median follow-up of 26 (4-65) months in haplo-HSCT and 36 (4-132) months in MSD-HSCT groups (P=0.294) , the incidences of grade Ⅰ-Ⅳ acute graft-versus-host disease (aGVHD) were 32.0% and 20.0% (P=0.343) , grade Ⅱ-Ⅳ aGVHD were 16.0%, 13.3% (P=0.759) , chronic GVHD were 30.7% and 24.6% (P=0.418) , moderate-severe chronic GVHD were 12.7% and 7.1% (P=0.522) respectively, in haplo-HSCT and MSD-HSCT groups. The incidences of infection were 32.0% (8/25) and 26.7% (4/15) (P=1.000) respectively, in haplo-HSCT and MSD-HSCT groups. No patients occurred early death and relapse. Three-year estimated overall survival (OS) were (86.5±7.3) % and (93.3 ±6.4) % (P=0.520) , GVHD-free and failure-free survival (GFFS) were (78.3±8.6) % and (92.9±6.9) % (P=0.250) respectively, in haplo-HSCT and MSD-HSCT groups. Conclusion: The preliminary results indicated that haplo-HSCT was a feasible choice for PNH with favorable outcomes, haplo-HSCT and MSD-HSCT produced similar therapeutic efficacy.

Objective: To compare the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for paroxysmal nocturnal hemoglobinuria (PNH) with paroxysmal nocturnal hemoglobinuria-aplastic anemia (PNH-AA) syndrome. Methods: The outcomes of 46 patients who received allo-HSCT (16 PNH patients, 30 PNH-AA patients) from July 10, 2007 to June 2, 2018 were analyzed retrospectively. The conditioning regimen was busulfan, cyclophosphoramide, and ATG in haploidentical donors and unrelated donors. Patients with matched sibling donors were treated with the fludarabine, cyclophosphamide, and ATG regimen. Results: There were no differences of baseline data between the 2 groups except gender distribution and the numbers of haploidentical donor transplantation. The median values of absolute nucleated cell counts were 10.58 (3.83-13.83) ×10(8)/kg in the PNH group and 10.81 (3.96-33.40) ×10(8)/kg in the PNH-AA group (P=0.668) . The median doses of CD34(+) cells infused were 5.00 (3.14-8.42) ×10(6)/kg and 3.57 (1.97-6.17) ×10(6)/kg (P=0.002) , respectively. All patients obtained complete engraftment. The median time for myeloid engraftment were 11 (7-14) days in the PNH group and 12 (10-26) days in the PNH-AA group (P=0.003) . The median time for platelet engraftment were 13 (11-16) days and 18 (12-75) days (P=0.002) , respectively, after a median follow-up of 36 (4-132) months in the PNH group and 26 (4-75) months in the PNH-AA group (P=0.428) . There were no differences of incidence rates of acute graft-versus-host disease (aGVHD) , chronic GVHD and infection between PNH and PNH-AA groups (P>0.05) . No patient occurred early death and relapse. The estimated 3-year overall survival (OS) of PNH and PNH-AA groups were (100.0±0.0) % and (85.7± 6.6) % (P=0.141) , GVHD-free and failure-free survival (GFFS) were (100.0±0.0) %, (78.7±7.7) % (P=0.067) . Conclusions: allo-HSCT is effective for patients with PNH and PNH-AA syndrome. The preliminary results indicate that myeloid and platelet engraftment in PNH group were faster than PNH-AA group. There were no differences in OS and GFFS between PNH group and PNH-AA group.
