Objective To investigate clinical features,drug resistance,risk factors and prognosis of extended-spectrum beta-lactamases (ESBLs)-producing Escherichia coli infection in hospitalized newborns.Methods Sixty eight newborns infected with ESBLs-producing Escherichia coli admitted in Neonatal Ward of Ningbo Women and Children's Hospital during.January 2010 and January 2013 were enrolled in the study; 81 newborns infected with multiple resistant non-ESBLs-producing Escherichia coli served as controls.The drug sensitivity of the isolated ESBLs-producing Escherichia coli was tested using K-B method.Clinical data including birth weight,gestational age,mode of delivery,site of infection and disease outcome were analyzed.Logistic regression analysis was performed to study the risk factors for ESBLs-producing Escherichia coli infection.Results The highest positive rate of ESBLs-producing Escherichia coli was detected in sputum samples (49/68,72.1％),followed by blood (7/68,10.3％) and urine (6/68,8.8％) samples.Strains were highly resistant to ampicillin,cefotaxime,ceftazidime and cefepime (61.8％-100.0％),but the resistant rates to cefoxitin,cefoperazone/sulbactam and amikacin were low (2.9％-10.3％),and were completely sensitive to carbapenems.Lower respiratory tract infections were most popular in both groups,but in ESBLs-producing Escherichia coli infected group,lower respiratory tract infection rate in late newborns was higher than that in early newborns (x2 =12.879,P ＜ 0.05).Multivariate logistic regression analysis showed that gestational age ＜ 37 weeks (Exp (B) =0.352,95％ CI:0.134-0.929),cesarean section (Exp (B) =0.488,95 ％ CI:0.243-0.984),invasive procedures (Exp (B) =0.363,95 ％ CI:0.142-0.927),use of hormones and/or antibiotics one week before birth (Exp (B)=0.325,95％ CI:0.127-0.833) were independent risk factors for ESBLs-producing Escherichia coli infection.Conclusions Respiratory tract infection is popular in ESBLs-producing Escherichia coli infection in hospitalized newborns.The strains are highly resistant to most antibiotics.Reducing invasive procedures,strict control of cesarean section and prenatal use of hormones and antibiotics may reduce the infection of ESBLs-producing Escherichia coli in newborns.

BACKGROUND:With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear hyoid bone position indicator for normal population has important implications for the change of hyoid bone position before and after orthodontics. OBJECTIVE:To determine the cone-beam CT measurement range of hyoid bone position in populations aged 6-19 years from Shandong, so as to provide a reference marker for the change of hyoid bone position before and after orthodontics in local children and adolescents. METHODS:Totaly 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong Province were subjected to cone-beam CT scan of the hyoid bone. Mimics10.01 was used to evaluate the linear and angular measurements of hyoid bone position, and then the normal value range was confirmed. Independent-samplet-test was used for analysis of gender difference and 95% confidence interval was calculated. RESULTS AND CONCLUSION: There were gender differences in a part of indicators of hyoid bone position among 14-15 years, 16-17 years, 18-19 years groups (P < 0.05). For children aged 12-13 years, the hyoid bone position vertical to the base of skul and upper jaw bone is lower in males than in females. For children aged 14-15 years and 18-19 years, the hyoid bone horizontal to the cervical spine is more forward in males than in females.

Objective To study the expressions of XIAP and survivin in breast carcinoma tissues and their(value) in predicting the recurrence of breast carcinoma.Methods The expression of XIAP and survivin in 65 benign and 65 malignant breast paraffin-embedded specimens was detected by using immunohistochemical assay and the results were compared.Results The positive rate of XIAP and survivin in recurrent breast carcinoma(recurrent group) was 82.2% and 85.7% respectively,and in non-recurrent breast carcinoma tissue(non-recurrent group) was 54.5% and 45.5% respectively,and in both groups were increased significantly as compared with that of benign breast tissues(20.0%,and 13.3% respectively).The positive expression of XIAP and survivin was increased significantly in recurrent group as compared with non-recurrent group(P

In the process of promoting the implementation and transformation of the Q3D guideline of the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) in China, the risk assessment of elemental impurities in naturally sourced excipients often faces challenges such as multiple types of elemental impurities and insufficient detection methods. In this paper, an inductively coupled plasma mass spectrometry (ICP-MS) method for screening 12 elemental impurities in titanium dioxide was established using the optimized acid extraction pre-treatment method. The accuracy and repeatability of the method were good. The recoveries of cadmium, lead, mercury, cobalt, nickel, lithium, barium, molybdenum, copper, chromium and iron were 83.6%−101.6%, the recovery of antimony was 54.1%, and the RSD was 1.1%−10.2% (n=6). The evaluation results of elemental impurities showed that the risk of cadmium, mercury, cobalt, nickel, lithium, barium, molybdenum, copper, chromium and antimony was low, while the risk of lead was high, and it is recommended that a lead salt test be added to the pharmacopoeia standard for this product. Based on the statistical data, the differences in the control levels of elemental impurities and whiteness of 29 batches of titanium dioxide samples from 10 domestic and foreign manufacturers were compared and analyzed. The Pearson correlation coefficient method was used to analyze the correlation between residual elemental impurities and whiteness, and a heat map was used to visualize the results. The results showed that whiteness was significantly negatively correlated with the amount of residual barium and the sum of residual elemental impurities. It is suggested that the manufactures should include whiteness as an internally controlled indicator to further improve the quality of titanium dioxide used as a pharmaceutical excipient.

Nucleos(t)ide analogues (NAs) are effective inhibitors for HBV replication and have become the preferred antiviral regimen for most patients with chronic hepatitis B (CHB). HBeAg seroconversion is an important index used to evaluate the durability and efficacy of antiviral therapy in HBeAg-positive CHB patients. The search for biomarkers that can predict HBeAg clearance or seroconversion after NAs treatment plays an important role in the selection of antiviral drugs, the adjustment of treatment regimens, and the achievement of individualized treatment. This article reviews the value of related markers, including HBV DNA, HBV RNA, anti-HBc, and HBcrAg, in predicting HBeAg clearance or seroconversion in CHB patients treated with NAs.

ObjectiveTo investigate the effect of follow-ups on medical compliance behaviors and quality of life of patients with gastroesophageal reflux disease (GERD).Methods One hundred GERD patients who were hospitalized in our department from June 2012 to June 2013 were divided into intervention group (n=50) and control group (n=50) according to the random number table. Both groups received the same drug treatment and conventional nursing during hospitalization.The control group received periodically outpatient follow-ups,while the intervention group received professional follow-ups by trained nurses after discharge from hospital. The compliance behaviors and quality of life in these patients were assessed and statistically analyzed after 6 months nursing intervention or outpatient follow-up.Results With the implement of follow-up in patients with GERD,the intervention group was better than the control group in compliance behaviors,including the decrement of smoking and drinking,strong tea,coffee,having midnight snack and spicy food (P<0.05),but there was no difference in the behavior of staying-up between the two groups.Concerning the quality of life,the intervention group was significantly better than the control group in the 6 items excluding the physical and physiological functions (P<0.05).Conclusion Professional follow-ups can improve compliance behavior and quality of life of GERD patients.
