Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

OBJECTIVE: To study insulin sensitivity and the serum level of adiponectin in infants with intrauterine growth retardation (IUGR) and the effect of breastfeeding on the insulin sensitivity through a follow-up study. METHODS: A total of 106 full-term IUGR infants who were hospitalized from October 2014 to October 2018 were enrolled as the IUGR group, and 90 full-term appropriate for gestational age (AGA) infants who were born during the same period of time were enrolled as the AGA group. Birth weight and body length were recorded. Serum levels of fasting blood glucose (FBG), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), insulin, and adiponectin were measured on day 7 after birth. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. According to the feeding pattern, the IUGR group was further divided into a breastfeeding group with 37 infants and a formula feeding group with 42 infants. The above serum indices and growth indices were also measured at the age of 3 and 6 months. RESULTS: Compared with the AGA group, the IUGR group had significantly increased levels in serum insulin and HOMA-IR and a significantly decreased level of adiponectin (P<0.05). There were no significant differences between the breastfeeding and formula feeding groups in growth indices and serum levels of FBG, TG, LDL, and HDL on day 7 after birth and at the ages of 3 and 6 months (P>0.05). In the breastfeeding group, serum insulin and HOMA-IR decreased and adiponectin level increased over the time of breastfeeding (P<0.05). CONCLUSIONS Insulin sensitivity decreases in the early stage after birth in IUGR infants, and breastfeeding can improve insulin sensitivity.

OBJECTIVETo explore the effect of intrauterine growth retardation (IUGR) on insulin sensitivity in neonates and the relationship between insulin sensitivity and plasma adiponectin level.

METHODSEighty-two term neonates with IUGR and 90 term neonates born appropriate for gestational age (AGA) were enrolled. Weight, height, head circumference and abdomen circumference of the neonates were measured within 24 hours after birth. Fasting serum glucose (FG), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), plasma insulin and adiponectin were detected in two groups on the 7th day after birth. Homeostasis model assessment for insulin resistance (HOMA-IR) index and insulin sensitivity index (ISI) were calculated.

RESULTSThere were no significant differences in the levels of FG, TG, HDL and LDL between the IUGR and AGA groups (P>0.05). The plasma insulin level in the IUGR group was higher than that in the AGA group, but the plasma adiponectin level was lower than that in the AGA group (P<0.05). HOMA-IR index in the IUGR group was higher than that in the AGA group, but ISI was lower than that in the AGA group (P<0.05). Both Pearson correlation analysis and multiple linear regression analysis showed HOMA-IR index was negatively correlated with plasma adiponectin level and birth weight (P<0.05).

CONCLUSIONSThe neonates with IUGR display a higher plasma insulin level and decreased insulin sensitivity. The decreased plasma adiponectin level may be associated with the decreased insulin sensitivity.

Objective:TThe aim of this study was to observe the changes of the volume and distribution of body fluid after abdominal surgery,and further to explore its characteristics and influence factors.Methods:Sixtyone patients were included between March and June in 2016.The volume of intracellular water (ICW),extracellular water (ECW) and total body water (TBW) was estimated by InbodyS 10 on preoperative day 1 (PreD 1) and postoperative day (POD) 1,3,5 and 7.Furthermore,the patients were grouped according to the age,sex,type of operation,operation time and the daily liquid input,and the influence factors of postoperative fluid volume were analyzed in each subgroup.Results:Comparing to that of PreD1,the ICW,ECW,and TBW,mainly ECW,were increased significantly on POD1 (P＜ 0.05),and the level of postoperative fluid volume was decreased to that of PreD1 between POD3 and POD7.It showed that there was difference in the net increasing of body fluid on POD1 between different type of the patients.Obviously,the net increasing of fluid volume in woman on POD 1 was more than that in man.The net increasing of fluid volume on POD1 was correlated with the operation time and net liquid input.Conclusion:The fluid retention was found in the early stage of postoperative patients,and mainly exists in ECW.The main influence factors resulting postoperative fluid retention were prolonged operation time and increased net fluid input.

OBJECTIVETo investigate the factors related to clinical pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) in women with secondary infertility.

METHODSThe clinical, laboratory and follow-up data of 1129 cycles in 1099 patients with secondary infertility undergoing IVF-ET in Women's Hospital, Zhejiang University School of Medicine between July 2012 to July 2014 were retrospectively reviewed. The factors related to pregnancy outcomes were analyzed by univariate and logistic regression methods. The clinical pregnancy rates in women with different age and different number of embryos transferred were compared. The clinical outcomes of stimulation with gonadotropin releasing hormone (GnRH) agonist long protocol, GnRH agonist short protocol and GnH antagonist protocol were evaluated in secondary infertile patients aged ≥ 40 years.

RESULTSAmong 1129 cycles, 376 cases (33.30%) had clinical pregnancy and 753 cases (66.70%) had no clinical pregnancy. There were significant differences in age, body mass index, basal follicle-stimulating hormone level, antral follicle number,paternal age and number of embryos transferred between pregnancy and no pregnancy groups (P<0.05); while only maternal age (OR=0.900, 95% CI: 0.873~0.928, P<0.001) and the number of embryos transferred (OR=2.248, 95% CI: 1.906~2.652, P<0.001) were the independent factors affecting the clinical pregnancy outcome of IVF-ET. There was no significant difference in clinical pregnancy rate between women aged 30~40 years with two embryos transferred and those aged<30 years with two or three embryos transferred(P>0.05). There were no significances in clinical pregnancy rate among women aged ≥ 40 years using GnRH agonist long protocol,GnRH agonist short protocol and GnRH antagonist protocol for stimulation (P>0.05).

CONCLUSIONMaternal age and number of embryos transferred have independent effect on IVF-ET clinical pregnancy outcome of secondary infertile women. We suggest that no more than two embryos should be transferred for women in their thirties to minimize the risk of multiple pregnancy while still having an acceptable pregnancy rate. The pregnancy rate of patients over 40 years decreases significantly, and there is no difference in pregnancy rate by using GnRH agonist long protocol, GnRH agonist short protocol or GnRH antagonist protocol.

OBJECTIVETo investigate the effect of Qiguiyin Decoction, QGYD) on multidrug-resistant Pseudomonas aeruginosa infection in Sprague-Dawley (SD) rats.

METHODSA pseudomonal infection model in SD rats was established by injecting multidrug-resistant P. aeruginosa intraperitoneally. Infected rats were randomized into four groups treated with Pure water, QGYD, ceftazidime, or combined QGYD and ceftazidime. Blood samples were obtained from the abdominal aorta. Serum was then collected and analyzed by peptide array for immune responsiveness to multidrug-resistant beta-lactamase proteins, including Verona integronen-coded metallo-beta-lactamase 1 (VIM-1), Sao Paulo metallo-beta-lactamase 1 (SPM-1), and Temoniera (TEMs). Blood levels of interleukin-1β (IL-1β), interleukin-4 (IL-4), and interferon-γ (IFN-γ) were assessed by enzyme-linked immunosorbent assay.

RESULTSQGYD enhanced antibody reactivity against VIM-1 [epitopes 7-11 and 36-40] and TEM-1 [epitopes 26-27, 52-55, and 66-70]. QGYD treatment restored the compromised antibody reactivity against VIM-1 [epitopes 53-54 and 56-58] and SPM-1 [epitopes 16-19 and 82-85] following pseudomonal infection. Serum levels of IL-1β and Th1/Th2 in the rats were significantly elevated following pseudomonal infection (P<0.05 orP<0.01). In contrast, QGYD and combination QGYD and ceftazidime treatment restored the elevated serum IL-1β and Th1/Th2 levels to normal (P>0.05).

CONCLUSIONSQGYD improves the immune response to pseudomonal infection in rats by stimulating the production of protective antibodies against drug-resistant proteins VIM-1, SPM-1, and TEM-1. In addition, it protects the immune system and maintains immune responsiveness by restoring IL-1β and Th1/Th2 levels.
