Objective To investigate the expression of estrogen receptor (ER), progesterone recptor (PR) and c-erbB-2 in breast cancer tissues and its relationship with prognostic factors. Methods The clinical data of 1 008 cases with breast cancer were retrospectively analysed. The relationship between the expression of ER, PR and c-erbB-2 in breast cancer tissues and the prognostic factors such as menopausal status, axillary lymph nodes metastasis and TNM stage was investigated. Results The mean presentation age of the 1 008 cases was (53.53?12.60) years. Invasive ductal cancer was the most common pathological type (80.5%). Postmenopausal ER-positive cases were significantly more than premenopausal ER-positive ones, and the clinical stage was lower (P

Jaundice can occur in most neonates.Most jaundice is benign,but beacuse of the potential toxicity of bilirubin,newborn infants with severe hyperbilirubinemia can develop acute bilirubin encephalopathy or kernicterus.In October 2004,American(academic) of pediatrics produced the latest guideline for newborn jaundice aim to reduce the incidence of acute bilirubin encephalopathy or kernicterus and avoid unnecessary costs or treatment.The latest guideline emphasizes the important of successful breastfeeding,time of jaundice developed,assessment for the risk of severe hyperbilirubinemia,close follow-up,and prompt intervention when indicated,provide a framework for the prevention and management of hyperbilirubinemia in newborn infants of 35 or more weeks of gestation.Some new view in the latest guideline may be helpful to us.

Objective To evaluate the efficacy of transversus abdominis plane (TAP) block for postoperative analgesia in the pediatric patients undergoing operation on the inguinal region.Methods Sixty-four pediatric patients of both sexes, aged 1-3 yr, weighing 8.5-23.6 kg, of American Society of Anesthesiologists physical status Ⅰ , undergoing elective unilateral high ligation of the hernia sac or high ligation of the processus vaginalis, were equally randomized into either intravenous analgesia group (group VA) or TAP block group (group TAP).In group TAP, after induction of anesthesia, the pediatric patients received ultrasound-guided TAP block with 0.2％ ropivacaine 1 ml/kg injected locally.After the laryngeal mask airway was inserted, the pediatric patients were mechanically ventilated, and then inhaled 2％-3％ sevoflurane for maintenance of anesthesia.In group VA, postoperative analgesia was performed with fentanyl 0.35 μg · kg-1 · h-1 until 24 h after operation.The level of pain was rated using the FLACC pain scale.When FLACC score＞5, fentanyl 0.25 μg/kg was injected intravenously as rescue analgesic.The occurrence of TAP block-related adverse events, time for removal of laryngeal mask airway, and occurrence of fentanyl-related nausea and vomiting, respiratory depression, and emergence agitation were recorded.Results No TAP block-related adverse events were observed in group TAP, and no respiratory depression was found in the two groups.Compared with group VA, the time for removal of laryngeal mask airway was significantly shortened, and the requirement for rescue analgesics and incidence of vomiting and emergence agitation were decreased in group TAP (P＜ 0.05).Conclusion TAP block with 0.2％ ropivacaine 1 ml/kg provides good efficacy for postoperative analgesia with good safety in the pediatric patients undergoing operation on the inguinal region.

Objective To study the effect of quercetin on proliferation and expression of P38MAPK and HMGB1 protein in neonatal rat cardiac fibroblasts induced by TNF-α.Methods Purified cardiac fibroblasts were obtained by trypsin digestion and differential adherence method.The proliferation of cardiac fibroblasts was detected by MTT assay.The expression of P38MAPK and HMGB1 protein was detected by Western blot.Results Quercetin had no effect on the proliferation of cardiac fibroblasts in the basal state but inhibited the proliferation of cardiac fibroblasts induced by TNF-α,and the A value of each group was increased with the increase of quereetin concentration(P＜0.05).The exspression of P38MAPK、HMGB1 were decresed with the icrease of quercetin.Conclusion Quercetin may inhibit the proliferation of cardiac fibroblasts induced by TNF-α.The mechanism may be inhibit the expression of HMGB1 through P38MAPK signaling pathway.

Objective To investigate the bone metabolism of children with leukemia and its relationship to tumor necrosis factor-?(TNF-?)pre-and post-treatment.Methods Serum bone gla protein(BGP),the excretion rate of urianry deoxypyridinoline(DPD)and TNF-? were measured in 35 children with leucocythemia pre-and post-treatment and 30 normal children(control group).Results The results showed that BGP,the excretion rate of DPD and TNF-? in children with leucocythemia before treatment were significantly higher than those in control group.However,the excretion rate of DPD decreased after chemotherapy but still significantly higher than that of control group(P0.05).Conclusions In children with leukemia,there are bone absorption and bone dissolution before chemotherapy,while there is osteogenesis dysfunction and bone absorption after chemotherapy.TNF-? can be used as a parametre for evaluating treatment effect and monitoring relapse.
