Objective:To observe the effects of genistein on proliferation and apoptosis of human non -small cell lung cancer cell line A549/DDP.Methods:①MTT assay was applied to evaluate the resistance index of A 549/DDP cell line to cisplatin and half in-hibitory concentration ( IC50 ) .②Inhibition rate of A549/DDP cell proliferation and IC 50 value were evaluated by MTT assay after treat-ment with 0, 1.25, 2.5, 5.0, 10, 20, 40, 60, 80 μg/ml genistein for 48 hour respectively.③A549/DDP cell cycle and apoptosis were evaluated by flow cytometry after treatment with 6.25, 12.5, 25 μg/ml genistein for 24 hours respectively.Results:①In expo-sing to cisplatin, the IC50 of A549 and A549/DDP was 33.6 μmol/L and 76.9 μmol/L respectively.The resistance index was 2.3. Cell growth inhibition rate increased following the cisplatin concentration increasing gradually .②A549/DDP growth inhibition rate in-creased at first and later decreased gradually following treatment with the genistein dose increased .The IC50 of A549 and A549/DDP was about 85.1 μg/ml and 80.2μg/ml respectively.③After treatment with 6.25, 12.5, 25μg/ml genistein for 24 hours, there were more A549/DDP cells arresting and showing apoptosis along with the genistein dose increased .Conclusion: Genistein can inhibit A549/DDP proliferation, cause A549/DDP arresting in G2/M phase and induce A549/DDP cell apoptosis with dose dependently .

Serum tumor necrosis factor-?(TNF-?) and interleukin-6 (IL-6) levels were measured in patients with simple hyperuricemia or hyperlipidemia combined with hyperglycemia and hyperuricemia.The results showed that TNF-?,IL-6 levels in patients with hyperuricemia were higher than those in normal controls (both P

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

Objectives To analyze the incidence of cranial nerve injury in patients after receiving carotid endarterectomy ( CEA) in a single-center and to investigate its correlation with surgical experiences. Methods The clinical data of patients underwent CEA at Beijing Xuanwu Hospital, Capital Medical University from January. 2001 to December 2013 were analyzed retrospectively. Cranial nerve injury was assessed at day 7 after procedure according to the clinical symptoms,and they were followed up at 1,3,6, and 12 months. The incidence of permanent cranial nerve injury was evaluated. The incidences of permanent cranial nerve injury were further analyzed at two time periods ( from January 2001 to September 2011 and from October 2011 to December 2013 ) . Results ( 1 ) A total of 598 consecutive patients treated with CEA were enrolled,and 15 (2. 5%) of them had cranial nerve injury,including 2 (0. 3%) facial nerve injury,7 (1. 2%) hypoglossal nerve injury,and 6 (1. 0%) vagus nerve injury. Only 1 case (0. 2%) did not recover completely at 6 months after procedure. ( 2 ) The patients with cranial nerve injury were 10 (3. 2%,10/308) and 5 (1. 7%,5/290) respectively from January 2001 to September 2011 and from October 2011 to December 2013). There was no significant difference (P < 0. 05). Conclusion The incidence of cranial nerve injury was low after CEA,and most patients could recover completely. The increased surgical experiences did not show the reduction of cranial nerve injury rate evidently after CEA.

Objective To explore the effects of human umbilical cord mesenchymal stem cells (HUC?MSCs) on podocytic apoptosis and injury induced by high glucose (HG) and the underlying mechanisms. Methods Podocytes were divided into six groups according to treatment: ⑴ normal glucose group (NG);⑵high glucose group (HG);⑶mannitol control group (NG+Ma);⑷HUC?MSC co?culture group (HUC?MSCs); ⑸ recombinant human hepatocyte growth factor treatment group (rhHGF);⑹ neutralizing antibody group(HGF?NtAb). Cytometry and Hoechst staining were used to detect the apoptosis rates. Western blot was used to measure the ratio of active PARP to total PARP and the level of Bcl?2. Immunofluorescence was used to study podocytic apoptosis and injury. Neutralizing antibody (NtAb) was used to block its function and the recombinant cytokine was added to induce its function. Results High glucose induced podocytic apoptosis in a time?dependent manner, HUC?MSCs co?culture decreased the podocytic apoptosis rate and the expression of PARP (all P﹤0.05), increased the expression of Bcl?2, prevented the reduced expression and maintained the normal arrangement of podocytic podoplanin. The rhHGF prevented podocytic apoptosis and injury similarly to HUC?MSCs, the beneficial effect of HUC?MSC decreased when blockade of HGF. Conclusions HUC?MSCs co?culture ameliorates podocytic apoptosis and injure induced by HG, probably through secreting soluble HGF.

Objective To explore the efficacy and safety of bedside continuous blood purification (CBP) in the treatment of critically ill neonates.Methods Totally ten critically ill neonates were hospitalized in Department of Neonatal Intensive Care Unit (NICU) in Shanghai Children's Hospital from June 2011 to May 2015, and managed with CBP treatment.The indications of CBP therapy were multiple organ dysfunction syndrome (MODS) failed to conventional treatment or combined with acute renal failure (ARF).The model for CBP was continuous veno-venous hemofiltration dialysis (CVVH).The clinical outcomes included blood electrolytes, serum bio markers, urine output, hemodynamic indicators, dose of intravenous epinephrine before treatment, 6, 12, 24, 48 h after treatment and at the end of CBP.Complications of CBP were also observed.Statistical analysis was performed with ANOVA and Dunnett-t test.Results The underlying problems of the ten newborns were septicemia (n=5), severe neonatal asphyxia (n=2), congenital hereditary metabolic disease (n=2) and traumatic asphyxia (n=l).The venous catheter was successfully inserted for all babies and CBP treatment continued for (86.7 ± 25.9) h averagely with obvious effect.Four of the ten cases were cured and discharged, and the rest six refused to treatment and died after due to irreversible injury of the nervous system although they had survived from the oliguric stage of ARF.The complications of CBP included thrombocytopenia (n=3), catheter blockage (n=2), hypotension (n=l).No hypothermia, thrombosis, bleeding or infection occurred.The mean blood pressure and partial pressure of oxygen in arterial blood/fraction of inspiration oxygen (PaO2/ FiO2) of the ten cases 6 h after the beginning of treatment were higher than those before [(46.4 ± 7.5) vs (36.5 ±8.3) mmHg, 1 mmHg=0.133 kPa;(210.0±62.0) vs (93.0±43.0) mmHg;t=2.647 and 6.378, both P ＜ 0.05].At the 12th hour since treatment start, the blood pH value was 7.4 ± 0.2, which was higher than that before treatment (6.9 ± 0.2, t=2.731, P ＜ 0.05), and kept in normal range.At the 24th hour, the serum levels of potassium, urea nitrogen and creatinine dropped to normal range compared to those before treatment [(4.8±2.9) vs (9.6± 3.6) mmol/L;(7.2±2.3) vs (13.6±6.3) mmol/L;(51.0± 12.0) vs (172.0±23.0) μ mol/L;t=4.571, 5.427 and 21.672, all P ＜ 0.05].Urine output increased from zero before the treatment to (0.7±0.3) ml/(kg · h) after 24 h (t=3.284, P ＜ 0.05).The maintaining dose of intravenous epinephrine decreased since 12 h after the beginning of treatment and was ceased at the 48th hour.Conclusion CBP is an effective and feasible treatment for critically ill neonates.

Objective Neuropsychiatric systemic lupus erythematosus ( SLE) is a common complication of SLE, whose path-ogenesis is not yet clear but associated with the alteration of cerebral blood flow ( CBF) in some studies.This study was to investigate the CBF alteration in SLE patients without overt neuropsychiatric symptoms by arterial spin labeling ( ASL) MRI. Methods Twenty-eight SLE patients without overt neuropsychiatric symptoms and 30 age-and sex-matched healthy controls underwent conventional MRI and ASL examinations, and all received such neuropsychologic tests as number connecting test-A ( NCT-A ) , digit symbol test ( DST ) , self-rating anxiety scale ( SAS ) , and self-rating depression scale ( SDS) .Independent sample-t test was used to detect the mean CBF in the whole brain, gray matter, and white matter of the SLE patients and healthy controls.The voxel-wise CBF maps of the two groups of subjects were further analyzed with the SPM8 software to compare the regional CBF between the two groups, followed by evaluation of the correlation between the regional CBF values and clinical markers. Results In comparison with the healthy controls, the SLE pa-tients showed significantly reduced CBF in the gray matter (40.5 ±3.7 vs 37.3 ±6.5, P=0.028) and the whole brain (38.0 ±3.5 vs 35.1 ±6.1, P=0.032), especially in the supplementary motor area and the adjacent middle cingulate, anterior cingulate, left medial frontal gyrus, left inferior frontal gyrus, and left insula (P<0.05, FWE corrected).The NCT-A score was negatively correlated with the CBF values of the left medial frontal gyrus (r=-0.402, P=0.032) and left inferior frontal gyrus (r=-0.382, P=0.045) of the SLE patients. Conclusion ASL and MRI showed significantly reduced cerebral blood flow in the SLE patient without overt neu-ropsychiatric manifestations, which was correlated with the change of the patient's cognitive function.

Objective To explore the clinical features, diagnosis, and treatment of non-immunologic hydrops fetalis (NIHF). Methods The clinical data of 10 cases of NIHF in neonatal intensive case unit during January 2011 to December 2016 were analyzed retrospectively. The related literatures were reviewed. Results In 10 cases of NIHF (6 males and 4 females). the gestational age were 32-42 weeks, and the birth weight was 2.25-3.95 kg. Among them, there were 3 cases of infectious diseases (cytomegalovirus, Streptococcus agalactiae, and parvovirus infection, one case each), 2 cases of fetal cardiovascular abnormalities, 2 cases of chromosomal abnormalities, 1 case of abnormal thoracic structures, 1 case of twin transfusion syndrome, and 1 case of etiology unknown of fetal hydrops. The clinical manifestations showed that there were 8 cases with 2 or more areas of edema (or hydrops), and only 2 cases with skin edema. Finally, 6 cases were cured and discharged, 2 cases were discharged by themself, and 2 cases died. Conclusions Prenatal ultrasound is a reliable method for the diagnosis of NIHF. Fetal edema in early pregnancy, especially with congenital malformations, is recommended for termination of pregnancy. After birth, NIHF should be diagnosed promptly so as to avoid or reduce severe complications.
