Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Objective To establish a simple and rapid method for the determination of 1,3-dideoxygalactonojirimycin in Bombycis Faeces, a potent glucosidase inihibitor, by HPLC. Methods A RP-HPLC method with fluorescence detection has been developed. Results The HPLC method developed in this research has a good reliability including accuracy and precision. The detection limit was less than 72 ng. Conclusion This method is sufficiently sensitive for determining 1,3-dideoxygalactonojirimycin in Bombycis Faeces and other related products.

ObjectiveTo investigate rational surgical approaches for Siewert type Ⅰ adenocarcinoma of the esophagogastric junction (AEG),and analyze the prognostic factors.MethodsThe clinical data of 103 patients with Siewert type Ⅰ AEG who were admitted to the Renji Hospital from January 2005 to December 2009 were retrospectively analyzed.All patients were divided into transthoracic approach group (61 patients) and thoracoabdominal approach group (42 patients).The incidences of numbers of lymph node dissected and postoperative complications of the 2 groups were compared using the chi-square test,Fisher exact probability or the t test.The survival curve was drawn by the Kaplan-Meier method and the survival was analyzed using the Log-rank test.Prognostic factors were analyzed using the one-way analysis of variance and Cox regression model.ResultsNo perioperative death was observed in the 2 groups.There were significant differences in the number of lymph node dissected and number of metastatic lymph node between the 2 groups (t =2.18,2.29,P ＜ 0.05 ).There was no significant difference in splenic injury between the 2 groups (P ＞ 0.05 ).There were no significant differences in postoperative bleeding,anastomotic fistula and stricture,esophagogastric reflux,pulmonary infection and esteomyelitis between the 2 groups (x2 =0.07,0.94,0.22,1.41,0.17,P＞0.05).Of the 103 patients,97(94.2％) were followed up.The mean postoperative survival time was 26 months.The median survival time was 26 months,and the 3-yearsurvival rate was 35.9％.The 3-year survival rates of transthoracic approach group and thoracoabdominal approach group were 32.8％ and 40.2％,with no significant difference between the 2 groups ( x2 =0.37,P ＞ 0.05).The results of univariate analysis showed that radical or palliative resection,TNM stage,lymph node metastasis stage,tumor diameter and metastasis rate,degree of radical resection were independent factors influencing the prognosis of patients with Siewert type Ⅰ AEG (x2 =21.07,26.04,22.42,6.26,32.20,20.80,P＜0.05).The results of multivariate analysis showed that degree of TNM stage,lymph node metastasis rate and radical resection were independent factors influencing the prognosis of patients ( Wald =12.01,8.75,10.03,P ＜ 0.05 ).Conclusions Thoracoabdominal approach is a reasonable selection for patients with Siewert type I AEG.Degree of TNM stage,lymph node metastasis rate and radical resection were independent risk factors influencing the prognosis of patients.

OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.

Based on ninety three acetylcholinesterase inhibitors (AChEIs) which have the same mechanism of action but are different in structural characteristics, the pharmacophore model for acetylcholinesterase inhibitor was constructed by the CATALYST system. The optimal pharmacophore model with three hydrophobic units, a ring aromatic unit and a hydrogen-bond acceptor unit were confirmed (Weight=3.29, RMS=0.53, total cost-null cost=62.75, Correl=0.93, Config=19.05). This pharmacophore model will act on the double active site of acetylcholinesterase and is able to predict the activity of known acetylcholinesterase inhibitors that are used for clinical treatment of Alzheimer's disease (AD), and can be further used to identify structurally diverse compounds that have higher activity treating with Alzheimer's disease (AD) by virtual screening.

Objective: To isolate the key domain of a novel polypeptide fragment from NGN-β that functions like intact NGF molecule.Methods: NGF-β had been treated with cyanogen bromide and trypsin skillfully. The peptide fragment with the activity inducing PC12 pheochromocytoma cells differentiation was isolated and purified by Sephadex G-50 gel filtration chromatography , DE-52 celluloseion exchange chromatography and C-18 reversed-phase column HPLC after NGF-β cleavaged by CNBr at 9th met then by trypsin at Arg or Lyscleavaged by CNBr at 9th met then by trypsin at Arg or Lys. Amino acid sequencing of this novel peptide fragment was performed by Automatic Amino Acid Analyser and Amino Acid Sequencer. Results: The functional fragment from cleavaged NGF might induce differentiation of PC12 cells. The fragment was consisting of two linear polypeptides . One of them was 16 peptide, GEFSVCDSVSVWVGDK , and other was 14 peptide, HWNSYCTTTHTFVK, linked by a disulphide bridge corresponding to residues 10～25 and 75～88, respectively, of the amino acid sequence of nerve growth factor, the result of biological activity assay in PC12 cells showed that the optimum concentration of this peptide were 0.001～0.1 μg*L-1. Conclusion: A novel peptide inducing differentiation of PC12 cell line of pheochromocytoma cells was obtained in the study. It′s isolation and purification successfully will underlie synthesis or expression of hyperactive neurotrophic small molecular substance although the relationship between the configuration and functions is not clearly.
