Objective To explore the expression of human epidermal growth factor receptor -3( HER3) in human epidermal growth factor receptor-2(HER2)-positive breast cancer and its relationship with the therapeutic effect of trastuzumab and clinical prognosis .Methods Clinicopathological characteristics of 235 HER2-positive breast cancer patients undergoing surgery in Jiangsu Cancer Hospital from Jan .2007 to Jun.2012 were analyzed retrospectively.The expression of HER3 was detected using immunohistochemisty staining .The expression of HER3 and its correlation with the clinicopathological characteristics were analyzed .All patients were followed-up to find out the impact of HER3 on the disease free survival and the therapeutic effect of trastuzumab .Results The positive rate of HER3 in Luminal B ( HER2 +) and HER2-overexpressing breast cancer was 100/135 (74.1%), and 85/100(85%)respectively.The difference had statistical significance (P<0.05).The histolog-ical grading and the lymph node metastasis were significantly different in Luminal B ( HER2+) breast cancer .The tumor volume , histological grading and lymph node metastasis were significantly different in HER 2-overexpressing breast cancer .The 5-year disease free survival of HER 2-positive breast cancer patients with negative HER 3 was higher than that with positive HER3.The non-relapse survival time was not significantly different between the pos-itive and negative HER 3 expression in Luminal B ( HER2+) breast cancer patients receiving trastuzumab treat-ment , but was significantly different in HER 2-overexpressing breast cancer patients .Conclusions HER3 is cor-related with unfavourable prognosis in HER 2-positive breast cancer .The treatment targeting HER3 may improve the clinical prognosis of both HER 2-positive and HER3-positive breast cancer patients .The HER2-overexpressing breast cancer patients with negative HER 3 may benefit more from trastuzumab treatment .

OBJECTIVETo study the protective effect of hyperoxia solution on acute lung injury caused by phosgene poisoning by observing the changes of PaO2 and malondialdehyde (MDA) contents, superoxide dismutase (SOD) activity in serum and Glutathione (GSH/GSSG) contents in lung tissues.

METHODSThe rabbits were divided into normal control group, hyperoxia solution (H0) and balance salt (BS) groups. Group HO and Group BS inhaled phosgene and the former was given intravenously hyperoxia solution (which was replaced by balance salt solution in Group BS). The content of MDA and the activity of SOD in serum were observed at different time points, the amount of GSH and GSSG in lung tissue were also measured.

RESULTS(1) The serum MDA contents increased and PaO2, SOD activity decreased significantly in Group HO and Group BS along with time increasing as compared with control group. The contents of GSH in lung tissue decreased in two groups compared with that in control group, however the contents of GSSG ascended instead. (2) At 3 and 8 h of the experiment, PaO2 of Group HO [(9.91 +/- 0.49), (9.15 +/- 0.46) mm Hg respectively] were significantly higher than those of Group BS [(9.03 +/- 0.76), (8.11 +/- 0.57) mm Hg respectively] (P < 0.01). The contents of MDA of Group HO (3.66 +/- 0.35), (5.31 +/- 0.15) micromol/L respectively] were lower than those of Group BS [(4.32 +/- 0.26), (7.4 +/- 0.33) micromol/L respectively] (P < 0.01). SOD activity in Group HO [(237.37 +/- 29.96), (208.10 +/- 18.80) NU/ml respectively] were higher than those of Group BS [(195.02 +/- 21.44), (144.87 +/- 21.26) NU/ml respectively] (P < 0.05 or P < 0.01). The content of GSSG lung tissue in Group HO (423.67 +/- 38.21) micromol/L were lower than those of Group BS (523.85 +/- 43.14) mol/L (P < 0.01). There were no significant differences in the content of GSH in lung tissues between Group HO and group BS.

CONCLUSIONHyperoxia solution can reduce acute lung injury of rabbits following phosgene poisoning.

BACKGROUND: Many studies have suggested that angiotensin-converting enzyme inhibitors(ACEI) protect blood vessels through anti-atherosclerosis independent of lowering blood pressure, but its mechanism is still unclear.OBJECTIVE: To investigate the anti-atherosclerotic mechanism of ACEI by observing the effects of Enalapril on lipoprotein(a) and oxygen free radicals in patients with acute myocardial infarction (AMI) .DESIGN: A controlled study based on the observation of the patients with AMI.SETTING: Second Department of the South Building, General Hospital of Chinese PLAPARTICIPANTS: Thirty-five inpatients with AMI(19 males and 16 females, aged 42 -75 years old, and averaged (62 ± 9) years old and hospitalized at the Department of Cardiology of Tianjin Harbor Hospital from April 2001 to August 2002 were chosen. These patients were randomly divided into 2 groups: the therapeutic group(20 cases) and the control group(15cases). Inclusion criteria: the diagnosis of patients with AMI was confirmed by WHO criteria. Exclusion criteria: patients with renal dysfunction, shock,hypotension, a history of allergy to ACEI, and a history of severe cough induced by ACEI. All patients had not taken ACEI in the past 2 weeks and agreed to participate in this study.METHODS: On early morning of the third day after AMI, patients in the treatment group took 5 mg of Enalapril one time. If they had no first-dose reaction of hypotension, on the fourth day after AMI, the patients of the treatment group were given a dose of 5 mg twice per day for the following 2 weeks. Then, they were given the drug at a dose of 10 mg twice per day for 2 weeks. The patients in the control group were not given Enalapril. Blood samples were taken respectvely prior to the administration and 2 weeks and 4 weeks after the administration in the two groups. Serum content of lipoprotein(a), oxygen free radicals, triglyceride, total cholesterol, high density lipoprotein(HDL) cholesterol, Apo(a) were measured.MAIN OUTCOME MEASURES: We compared the level of serum of lipoprotein (a), oxygen free radicals (OFR), triglyceride, total cholesterol,HDL cholesterol, Apo(a) pre-treatment and post-treatment respectively in patients of the two groups.RESULTS: Serum levels of OFR were significantly lowered in the treatment group, which were(1 423.14±216.23), (1 076.62±287.12) and (566.57 ± 138.02) U/mL respectively 2 weeks and 4 weeks before and after the treatment(t =2. 937, 3. 571, P ＜0. 01), but there were no significant changes in serum concentrations of lipoprotein(a) and lipids( P ＞ 0.05) .CONCLUSION: Enalapril improved the prognosis of patients with AMI by antioxidation, but not by lowering the serum levels of lipoprotein(a) and lipids. The study can serve as a theoretical reference that the mechanism of Enalapril might inhibit atherosclerosis in patients with AMI.

Objective To evaluate application of recombinant human luteinizing hormone (r-hLH)used in ovarian stimulation of assisted reproductive technique and impact on outcome of pregnancy. Methods From Apr. To Jul. 2009, 123 patients with low LH level ( < 1 U/L) at day 3 of menstruation and downregulation of pituitary function undergoing in vitro fertilization-embryo transfer (IVF-ET) in Reproductive Medical Center, Provincial Hospital Affiliated to Shandong University were enrolled in this study, whom were classified into 66 cases treated by r-hLH in r-hLH group and 57 cases without r-hLH treatment in non-r-hLH group. In the mean time, 145 patients with normal level of serum LH ( 1-2 U/L) not given by r-hLH treatment and undergoing IVF-ET were matched as control group. Total amount of gonadotropin, estradiol levels and LH levels on the administration of human chorionic gonadotropin ( hCG), number of oocytes retrieved, number of 2PN zygotes, rate of high quality embryos, the rates of implantation and clinical pregnancy were compared among these three groups. Results The level of serum LH on the day of hCG administration were ( 1.59 ± 0.77 ) U/L in r-hLH group, (0.54 ± 0.25 ) U/L in non-r-hLH group and (2.39 ± 1.01 ) U/L in control group, which reached tatistical difference between every two groups (P < 0.05). The rates of high quality embryo were 59.36％ in r-hLH group, 57.79％ in non-r-hLH group,which were significantly lower than 65.94％ in control group, respectively (P < 0. 05 ). The rates of 2PN were 67.62％ in r-hLH group and 68. 32％ in control group, which were significantly higher than 62. 84％ in non-r-hLH group, respectively ( P < 0.05 ). The rates of implantation of 29.77％ in r-hLH group were significantly higher than 18.26％ in non-r-hLH group ( P < 0.05 ). The total amount of gonadotropin,estradiol level on the day of hCG administration, the number of oocytes retrieved, and clinical pregnancy rate were not significantly different among those three groups ( P > 0.05 ). Conclusion The administration of recombinant human uteinizing hormone in patients who are profoundly suppressed after down-regulation with long protocol can get more quality embryos, the higher rates of 2PN and implantation.

A HPLC method of analysis of Monascus citrinin was established. More than 30 strains of Monascus spp. were cultured in steamed rice at solid state or in MSG liquid medium composed of monosodium glutamate as sole nitrogen source and glucose as sole carbon to investigate their ability of producing citrinin. The results indicated that most of the Monascus strains are able to produce citrinin. MSG medium can be used as a specific culture medium to qualitatively identify if the strain is the potential citrinin producer. But to confirm whether the Monascus strains are potential citrinin producers, these strains should be cultured in several cultivation methods, as the culture states and culture conditions influence the citrinin production greatly.

Heatstroke is a critical disease which usually catches in the hot environment in summer and abundant exercise that could bring about multiple organ dysfunction.The process of the occurrence and development of heatstroke includes of the compensatory phase,acute reaction stage and decompensation stage.The recent researches have shown that the mechanism of liver injury induced by heatstroke might be related to the direct action of heat,mitochondrial dysfunction in liver cells and cascade of inflammatory response,and each link promoted each other,finally caused liver injury.In addition,a cascade of inflammatory responses in the hepatic sinusoid might play a predominant role in liver injury induced by heatstroke.This paper aims to review the mechanism of liver damage caused by heatstroke in terms of the physiology and pathology,so as to provide perspectives for clinical prevention and treatment of liver injury.

Objective To analyze the trend of maternal mortality ratio (MMR) and cause of death in Shanghai from 1996 to 2015.Methods To collect the material about the maternal death and the maternal death audit from 1996 to 2015,and to analyze the MMR,the cause of death and the result of the maternal death audit of Shanghai from 1996 to 2015 retrospectively.Results (1) The change of MMR:the MMR in Shanghai decreased from 28.84 per 100000 live births in 1996 to 6.66 per 100000 live births in 2015.(2) The characteristic of maternal death:the proportion of Shanghai citizens was 27.4％(121/441) and the proportion of migrant women was 72.6％(320/441).The women with advanced maternal age was 8.2％(20/243) since 1996 to 2005,and increased to 16.7％ (33/198) since 2006 to 2015.Maternal deaths during pregnancy increased from 27.6％(67/243) in the first 10 years (1996-2005) to 35.4％(70/198) in the recent 10 years(2006-2015).The intrapartum maternal deaths was 6.2％(15/243) in the first 10 years and in the recent 10 years it was zero.The proportion of postpartum deaths in the first 10 years and in the recent 10 years were 66.3％ (161/243) and 64.6％(128/198) respectively.(3) The cause of maternal death:During the recent 10 years,indirect obstetric causes [63.1％(125/198)] was more than direct obstetric causes [36.9％(73/198)] for the first time.The death causes changed significantly.Postpartum hemorrhage remained the leading cause of maternal deaths,but the specific mortality rate (SMR) of postpartum hemorrhage decreased significantly from 7.42 per 100000 live births in the first 10 years to 1.51 per 100000 live births in the recent 10 years.The maternal deaths because of heart disease and cerebrovascular disease rose to the second and the forth reasons.(4) Maternal death audit:the avoidable maternal death ratio decreased from 3.66 per 100000 live births in the first 10 years to 1.86 per 100 000 live births in the recent 10 years.Conclusions During the past 20 years,the MMR of Shanghai decreased significantly and was close to the level of developed countries.In recent years,the causes of maternal death become more complicated.With the implementation of the second child policy,women with high risk factors increase,so government investment,policy support should be strengthened to optimize the management.
