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 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.

Purpose To investigate the effect of subcellular location of tumor BRCA1 on the sensitivity to ionizing radiation (IR) and PARP inhibitor.Methods siRNA of BRCA1 were first used to inhibit endougenous BRCA1 expression in MCF7 cells.Then,plasmids of pCMV-3xFlag-WT-BRCA1,pCMV-3xFlag-NES-BRCA1 and pCMV-3xFlag-NLS-BRCA1 were transfected in MCF7 cells.Immunofluorescence staining was used to detect BRCA1 subcellular location as well as the formation of Rad51 and γ-H2AX foci.Apoptotic cells were analyzed by flow cytometry,and colony formation assay was performed to evaluate the survival of cells.Results There were 47％ cells with nuclear BRCA1,23％ cells with cytoplasmic BRCA1 and 30％ cell with mixed nuclear and cytoplasmic BRCA1 expression in WT-BRCA1 transfected cell.There were 87％ cells with nuclear BRCA1 in NES-BRCA1 transfected cell,and 82％ cells with cytoplasmic BRCA1 in NLS-BRCA1 transfected cell.There were 87％,84％ and 13％ Rad51 foci positive cells at 2 hours after 4 Gy radiation treatment and 22％,25％ and 59％ γ-H2AX foci positive cells at 24 hours after 4Gy radiation treatment in WT-BRCA1,NES-BRCA1 mutant and NLS-BRCA1 mutant transfected cell respectively.ABT-888 and radiation treatment induced more apoptosis and fewer colonies in NLS-BRCA1 transfected cell than WT-BRCA1,NES-BRCA1 mutant transfected cell.Conclusion Subcellular location of BRCA1 might affect homologous recombination repair of DNA double strand breaks and can be used to predict sensitivity to IR and PARP inhibitor.

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.

OBJECTIVEThis study aimed to improve students' ability in practical and theoretical courses of oral health education and to promote students' learning interest and initiative.

METHODSFourth-year students of the oral medical profession from 2006 to 2008 at Weifang Medical University were chosen as research objects for oral health education to explore the experimental teaching reform. The students were divided into test and control groups, with the test group using the "speak out" way of teaching and the control group using the traditional teaching method. Results of after-class evaluation of the test group, as well as final examination and practice examination of the two groups, were analyzed and compared.

RESULTSAfter-class evaluation results of the test group showed that the "speak out" teaching method was recognized by the students and improved students' ability to understand oral health education. The final examination and practice examination results showed that the score of the test group was higher than that of the control group (P < 0.01).

CONCLUSION"Speak out" teaching methods can improve students' ability for oral health education, in accordance with the trend of teaching reform.

Objective To evaluate the clinical efficacy ofZi Wu Liu Zhu Na Jia needling (acupuncture based on midnight-noon ebb-flow theory) in treating spastic hemiplegia after cerebral stroke by using surface electromyography (sEMG).Method Fifty-two patients with spastic hemiplegia due to cerebral stroke were randomized into a treatment group and a control group, 26 cases each. The two groups were both intervened by conventional rehabilitation training. In addition, the treatment group was givenZi Wu Liu Zhu Na Jia needling and the control group was given ordinary acupuncture. The two groups were treated once a day, 15 sessions as a course. The ambulation ability, muscle tension, neurological deficit score (NDS), Fugl-Meyer Assessment Scale (FMA), and Berg Balance Scale (BBS) were evaluated before the intervention and after 2 treatment courses, and the sEMG signals were also collected and analyzed.Result The Holden's Functional Ambulation Classification (FAC) and Modified Ashworth Scale scores were significantly changed in the two groups after the intervention (P<0.01). After the intervention, the FAC and MAS scores in the treatment group were significantly different from those in the control group (P<0.05). The NDS, FMA and BBS scores were significantly changed in the two groups after the treatment (P<0.05). The NDS, FMA and BBS scores in the treatment group were significantly different from those in the control group after the treatment (P<0.05). Of the sEMG signals, H/M max in the treatment group was significantly different from that in the control group after the intervention (P<0.01).Zi Wu Liu Zhu Na Jia needling with rehabilitation training can significantly mitigate the muscle tension and promote the activities of daily living in patients with spastic hemiplegia after cerebral stroke.

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.
