Abstract
Objective: To explore the relationship between the embryo with the different morphological types in the third day and its mitochondrial copy number, the membrane potential. Methods: Totally 117 embryos with poor development after normal fertilization and were not suitable transferred in the fresh cycle and 106 frozen embryos that were discarded voluntarily by infertility patients with in vitro fertilization-embryo transfer after successful pregnancy were selected. According to evaluation of international standard in embryos, all cleavage stage embryos were divided into class Ⅰ frozen embryo group (n=64), class Ⅱ frozen embryo group (n=42) and class Ⅲ fresh embryonic group (not transplanted embryos; n=117). Real-time PCR and confocal microscopy methods were used to detect mitochondrial DNA (mtDNA) copy number and the mitochondrial membrane potential of a single embryo. The differences between embryo quality and mtDNA copy number and membrane potential of each group were compared. Results: The copy number of mtDNA and the mitochondrial membrane potential in class Ⅲ fresh embryonic group [(1.7±1.0)×10(5) copy/μl, 1.56±0.32] were significantly lower than those in class Ⅰ frozen embryo group [(3.4±1.7)×10(5) copy/μl, 2.66±0.21] and class Ⅱ frozen embryo group [(2.6±1.2)×10(5) copy/μl, 1.80±0.32; all P<0.05]. The copy number of mtDNA and the mitochondrial membrane potential in classⅠ frozen embryo group were significantly higher than those in classⅡ frozen embryo group (both P<0.05). Conclusion: The mtDNA copy number and the mitochondrial membrane potential of embryos of the better quality embryo are higher.

Abstract
Objective: To examine the features and values of ultrasonic diagnosis for retinal detachment in eyes with silicone oil tamponade (SOT). Methods: A prospective study. A total of 257 eyes (257 patients) were filled with silicone oil between December 1, 2015 and August 1, 2016 in the Department of Ophthalmology at a hospital in Beijing. All of the patients underwent a color Doppler ultrasound examination in the supine and sitting positions a week prior to surgery. The pre-surgery conditions were compared with the subsequent observations during the surgery to analyze the features and values of ultrasonic diagnosis for retinal detachment in eyes with SOT. Results: Ultrasound manifestations of eyes with SOT included pseudo extension of the ocular axis and an arc-shaped echo between the eye wall and silicone oil. Diagnostic accuracy was 85.6% in the supine position and 93.8% in the sitting position. Conclusion: Ultrasound diagnosis for retinal detachment in eyes with SOT manifests itself in certain patterns. Compared with the traditional ultrasound examination in the supine position, the sitting position examination can be used to further increase the diagnostic accuracy in the ultrasound diagnosis for retinal detachment in eyes with SOT, providing reliable evidence for clinical and differential diagnosis.

Abstract
A titratable thermoplastic mandibular advancement device (MAD) is clearly an effective treatment option in some patients with obstructive sleep apnea (OSA). Determining which patients may be more likely to respond to treatment with thermoplastic MADs and to adhere to treatment would be of obvious clinical relevance. This was an experimental descriptive study (N = 60). Patients with OSA were instructed to wear a titratable thermoplastic MAD for 3 months. Treatment success was defined as a ≥50% reduction from baseline in the apnea-hypopnea index (AHI) or AHI <10 when wearing MAD. Adherence was defined as MAD use ≥5 nights/week. Treatment was successful in 66.7% of patients and 60.0% were adherent. All polysomnographic parameters and visual analogue scale scores (sleep quality, snoring, waking refreshed) were significantly improved after treatment. The patients in whom treatment failed had significantly higher neck circumferences (39.3 cm vs. 37.5 cm, p = 0.014), higher baseline AHI values (26.6 vs. 18.0, p = 0.016), and smaller AHI reduction (-31.8 vs -53.1, p < 0.001) than those in the group in whom treatment succeeded. There were no significant differences in polysomnographic, cephalometric, or visual analogue scale measures between patients for whom treatment was and was not successful, regardless of baseline values or the change rates after the MAD was placed. Titratable thermoplastic MADs can improve indicators of sleep quality, even in patients in whom treatment is considered to have failed.

Abstract
AIM To investigate the effect of changes in fasting plasma glucose (FPG) variability, as assessed by 2-year trajectories of FPG variability, on mortality risk in patients with type 2 diabetes (T2D). METHODS From 2009 to 2012, outpatients with T2D, aged>18 years, were enrolled from a medical centre. FPG was measured every 3 months for 2 years in 3569 people. For each of the eight 3-month intervals, FPG variability and means were calculated, with variability defined as the coefficient of variation of FPG. Also, trajectories of FPG variability and means were determined separately, using group-based trajectory analysis with latent class growth models. These models were fitted using the SAS Proc Traj procedure. The primary outcome was all-cause mortality, which was followed-up to the end of 2014. RESULTS Five distinct trajectories of FPG variability (low, increasing, fluctuating, decreasing and high) and means (well controlled, stable control, worsening control, improving control and poor control) were established. The five trajectories of mean FPG were all associated with the same mortality risk. In contrast, in comparison to the low FPG variability trajectory, the fluctuating, decreasing and high variability trajectories all had significantly higher risks of mortality, with respective hazards ratios of 2.63 (95% CI: 1.40-4.93; P=0.003), 2.78 (95% CI: 1.33-5.80; P=0.007) and 4.44 (95% CI: 1.78-11.06; P=0.001) after multivariable adjustment. CONCLUSION Changes in FPG variability were independently associated with increased mortality risk in patients with T2D.

Abstract
Objective: To investigate the distribution patterns of 21-gene assay and its influencing factors in Chinese patients with early breast cancer. Methods: Nine hundred and twenty-seven early breast cancer patients were retrospectively recruited from January 2009 to December 2015 at Ruijin Hospital, Shanghai Jiaotong University School of Medicine. The 21-gene reverse transcriptase-polymerase chain reaction(RT-PCR) assay were conducted in paraffin-embedded tumor tissues to calculate the Recurrence Score(RS). Immunohistochemistry(IHC) assay was used to measure the expression levels of estrogen receptor(ER), progesterone receptor(PR) and Ki-67. Concordances of RT-PCR and IHC results were assessed. Correlations of RS and classical clinicopathological factors were evaluated, and logistic regression were applied to determine independent predictive factors for RS. Results: The median RS of 927 patients was 23(range: 0~90), and the proportions of patients categorized as having a low, intermediate, or high risk were 26.5%, 47.7% and 25.8%, respectively. The distribution of RS varied significantly according to different tumor grade, T stage, PR status, Ki-67 index and molecular subtypes(P<0.05 for all). Grade, PR status and Ki-67 index were independent predictive factors for RS. ER, PR status and Ki-67 index showed significantly correlation between RT-PCR and IHC assays, and the concordance rates for ER and PR status were 98.7% and 87.8%, respectively. Conclusions: RS significantly correlated with tumor grade, T stage, PR status, Ki-67 index and subtypes. Grade, PR status and Ki-67 index can independently predict RS. Remarkable concordances of ER, PR status and Ki-67 index are found between RT-PCR and IHC assays.

Abstract
BACKGROUND Development of drug therapies and other techniques for wound care have resulted in significant improvement of the cure rate and shortening of the healing time for wounds. A modified technique of regulated oxygen-enriched negative pressure-assisted wound therapy (RO-NPT) has been reported. AIM To evaluate the efficacy and impact of RO-NPT on wound recovery and inflammation. METHODS Infected wounds were established on 40 adult female white rabbits, which were then randomized to one of four groups: O2 group, regulated negative pressure-assisted wound therapy (RNPT) group, regulated oxygen-enriched negative pressure-assisted wound therapy (RO-NPT) group and healthy control (HC) group. Each day, the O2 group was treated with a constant oxygen supply (1 L/min) to the wound, while the RNPT group was treated with continuous regulated negative pressure (70 ± 5 mmHg) and the RNPT + O2 group was treated with both. The HC group was treated with gauze dressing alone, which was changed every day. Leucocyte count, colony count and wound-healing rate were calculated. Levels of tumour necrosis factor (TNF)-α, interleukin (IL)-1β and IL-8 were evaluated by ELISA. RESULTS RO-RNPT significantly decreased bacterial count and TNF-α level, and increased the wound-healing rate. IL-1β, IL-8 and leucocyte count had a tendency to increase in the early phase of inflammation and a tendency to decrease in the later phase of inflammation in the RO-RNPT group. CONCLUSIONS RO-NPT therapy assisted wound recovery and inflammation control compared with the RNPT and oxygen-enriched therapies. RO-NPT therapy also increased levels of IL-1β and IL-8 and attenuated expression of TNF-α in the early phase of inflammation.

Abstract
The present study aims to explore the role of stromal cell-derived factor-1α (SDF-1α)/stromal cell-derived factor receptor-4 (CXCR4) signaling pathway to the clinicopathological features and prognosis of patients with nasopharyngeal carcinoma (NPC). From January 2009 to December 2010, 102 patients with NPC and 80 patients with chronic nasopharyngitis were enrolled for the study. Immunohistochemical staining, quantitative real-time polymerase chain reaction (qRT-PCR), and Western blotting were employed to determine the expressions of SDF-1α and CXCR4 proteins in NPC tissues and chronic nasopharyngitis tissues. Chi-square test was conducted to analyze the associations of the expressions of SDF-1α and CXCR4 proteins with the clinicopathological features of NPC patients. Spearman rank correlation analysis was used to analyze the correlation between the SDF-1α protein expression and CXCR4 protein expression. The mRNA and protein expressions of SDF-1α and CXCR4 in NPC tissues were significantly higher than those in chronic nasopharyngitis tissues. The expressions of SDF-1α and CXCR4 proteins showed associations with T staging, N staging, tumor node metastasis (TNM) staging, skull base invasion, and cervical lymph node metastasis of NPC patients. Compared with NPC patients showing negative expressions of SDF-1α and CXCR4 proteins, those with positive expressions of SDF-1α and CXCR4 proteins had a significantly shorter survival time. SDF-1α protein, CXCR4 protein, EBV-IgG status, T staging, N staging, TNM staging, skull base invasion, and cervical lymph node metastasis were independent risk factors for the prognosis of NPC. The findings indicated that SDF-1α/CXCR4 signaling pathway might be associated with the clinicopathological features and prognosis of patients with NPC.

Abstract
OBJECTIVE To evaluate the impacts of the prognostic factors of T2N0M0 upper tract urothelial carcinoma (UTUC) for Chinese patients. METHODS A retrospective study was conducted including 235 patients who were diagnosed with T2N0M0 UTUC in our hospital and received radical nephroureterectomy (RNU) or partial ureterectomy during January 2000 and December 2013. The 3 and 5-year cancer-specific survival rates and bladder recurrence-free survival rates of all the patients were valued using Kaplan-Meier method, and the survival curves with statistical significance between the two were compared using the Log-rank test. Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model. RESULTS A total of 235 patients were included in this study, including 95 (40.4%) male patients and 140 (59.6%) female patients. The mean age was 66.73±10.49 years.The median follow-up time was 53 (rang: 3-142) months, and during the follow-up, 74 (31.5%) patients died of UTUC after a median of 35 months,and 96 (40.9%) patients developed intravesical recurrence after a median of 19.5 months. The 3 and 5-year cancer-specific survival rates of all the patients were 89.1% and 85.9%, respectively; the bladder recurrence-free survival rates were 85.5% and 80.2%, respectively. The independent prognostic factors of cancer-specific mortality were tumor age elder than 55 years (HR=3.138, 95%CI: 1.348-7.306, P=0.008) and diameter larger than 5 cm (HR=3.320, 95%CI: 1.882-5.857, P<0.001). The independent prognostic factors of bladder recurrence-free survival were ureter tumor (HR=1.757, 95%CI: 1.159-2.664, P=0.008) and lower tumor grade (HR=1.760, 95% CI: 1.151-2.692, P=0.009). CONCLUSION T2N0M0 UTUC has a better cancer-specific survival. The intravesical recurrence was equivalent to non-muscle invasive UTUC but earlier. The tumor diameter larger than 5 cm and the patient age elder than 55 years were independently associated with cancer-specific mortality; the primary tumor located in ureter and lower tumor grade were more likely to develop intravesical recurrence.

Abstract
BACKGROUND/PURPOSE Spaced primary dentition plays a critical role in the eruption of permanent teeth and the establishment of ideal occlusion. A lack of these spaces in deciduous dentition may result in disproportionate jaw and tooth sizes. Additionally, spaced primary dentition is significantly affected by ethnic factors. However, few of these studies have been conducted in Asia. The purpose of this study was to investigate the prevalence of spaced primary dentition in Taiwan. METHODS One hundred and forty-seven 3- to 6-year-old Taiwanese children (58 girls and 89 boys) were recruited for a cross-sectional study. Primate and interdental spaces were recorded by intraoral photos. The prevalence of spaced dentition was evaluated. The interpersonal agreement of spaced dentition between the upper and lower arches was also assessed. RESULTS Most of the subjects had spaced primary dentition. The prevalence of primate space was 83.7% in the upper arch and 61.2% in the lower arch, whereas the prevalence of interdental space was 44.2% in the upper arch and 53.1% in the lower arch. The prevalence rates of interdental space and upper primate space were significantly higher in boys than in girls. Interdental spaces of the lower arch increased with age. CONCLUSION Ethnic factors can affect the ratio of spaced dentition. Most of the 3- to 6-year-old Taiwanese children have spaced dentition. The boys have higher incidence of spaced dentition than the girls. Furthermore, primate space is more frequently found in the upper arch than in the lower arch, whereas interdental space is reversed.

Abstract
Objective: To evaluate the choice of surgical treatment of ductal carcinoma in situ (DCIS) and its impact on long-term outcomes. Methods: A retrospective analysis of the clinicopathological features and treatment protocol of DCIS patients who underwent surgical treatment in Comprehensive Breast Health Center, Ruijin Hospital, Shanghai Jiaotong University School of Medicine from January 2009 to August 2016 was done. The factors which could affect surgical treatment were analyzed by χ(2) test and Logistic regression. Survival analysis were performed between different surgical approaches. Kaplan-Meier survival curves and Log-rank tests demonstrated the distribution of disease free survival and overall survival. Results: A total of 526 patients were enrolled in this study, 405 cases (77.0%) underwent mastectomy, 121 cases (23.0%) underwent breast-conserving surgery, of which 88 cases received radiotherapy after breast-conserving surgery. It was shown by univariate and multivariate analysis that age>50 years (OR=0.631, 95% CI: 0.413 to 0.965, P=0.034), first symptom of nipple discharge (OR=0.316, 95% CI: 0.120 to 0.834, P=0.020), excision biopsy (OR=1.831, 95% CI: 1.182 to 2.835, P=0.007) and tumor size >3 cm (OR=0.422, 95% CI: 0.206 to 0.864, P=0.018) were significantly correlated with choice of surgical treatment for breast lesions. Axillary lymph node dissection was performed for 118 cases (22.4%), with sentinel lymph node biopsy for 327 cases (62.2%), and none for 81 cases (15.4%). There was significant statistical difference in the choice of axillary lymph node management in patients of different age (χ(2)=8.124, P=0.017), biopsy type (χ(2)=35.567, P=0.000), breast operation type (χ(2)=149.118, P=0.000) and tumor size (χ(2)=13.394, P=0.010). The 5-year disease free survival rates was 95.7%, 89.6% and 100%, respectively, for mastectomy group, breast-conserving surgery group and breast-conserving surgery plus radiotherapy group. And the 5-year overall survival rates for three groups were 99.0%, 100% and 100%. The differences were not statistically significant (P=0.427, 0.777). Conclusions: For DCIS patients, age, first symptom and tumor size are independent predictors of breast surgery. The choice of axillary lymph node surgery is influenced by age, biopsy, operation type, and tumor size. Different surgical treatment options has no significant effect on disease-free survival and overall survival in DCIS patients.

Abstract
Sleep-disordered breathing (SDB) and Eustachian tube disorders (ETDs) share the same risk factors. The specific aim of this study was to determine the correlation between these 2 conditions and to determine whether treatments for SDB reduce the risk of ETD.This is a retrospective and large population-based cohort study. According to Taiwan's National Health Insurance Research Database, out of 1,000,000 insured patients, 24,251 patients were newly diagnosed with SDB from year 2000 through 2009. The control group for this study comprised 96,827 patients without SDB who were randomly selected from the same database at a ratio of 1:4, frequency matched for sex, age, and index year of SDB. The incidence of developing ETD was compared between these 2 groups; the main covariates were demographic data, interventions, and medical comorbidities.There was an increased risk of developing ETD among the SDB cohort compared with the control group (hazard ratio = 1.51, 95% confidence interval = 1.41-1.63). Compared with SDB patients who did not receive treatment, those who received the treatment, that is, pharyngeal or nasal surgery, CPAP, or multiple modalities (both surgery and CPAP), had a significantly reduced risk of developing ETD.This study showed that patients with SDB are at an increased risk of developing ETD and other comorbidities. The risk of developing ETD can be reduced by implementing prompt treatment for SDB. Multidisciplinary evaluation including ETD should be conducted in the management of patients presenting with SDB.

Abstract
Objective: To investigate the effect of 21-gene recurrence score on adjuvant chemotherapy decisions for patients with estrogen receptor (ER)-positive, epidermal growth factor receptor 2 (HER-2)-negative and lymph node (LN)-negative early stage-breast cancer. Methods: One hundred and forty-eight patients with ER+ , HER-2- and LN- early stage breast cancer were recruited in the Ruijin hospital, Shanghai Jiao Tong University School of Medicine. The 21-gene recurrence score (RS)assay was performed and systemic therapeutic decisions were made before and after knowing the RS results under multidisciplinary discussion. The effects of RS assay and the other influential factors on adjuvant chemotherapy decision were further analyzed. Results: After knowing the RS results, treatment decisions were changed in 26 out of 148 patients(17.6%). Among them, 9 out of 26 patients were not recommended for chemotherapy; 16 of 26 had treatment recommendation changed to chemotherapy, and chemotherapy regimen was changed in the last one patient. Multivariate analysis showed that RS, age and histological grade were independent factors of decision-making for adjuvant chemotherapy. Conclusion: Our results suggest that 21-gene recurrence score significantly influences decision making for adjuvant chemotherapy in patients with ER+ , HER-2- and LN- early stage breast cancer.

Abstract
Objective: To analyze adjuvant chemotherapy decisions for triple negative breast cancer (TNBC), and explore the influencing factors in the multidisciplinary treatment (MDT) modality. Methods: A retrospective analysis was performed. The cases with invasive TNBC who underwent surgery and MDT discussion for adjuvant treatment in Ruijin Hospital, from April 2013 to June 2015, were recruited. The patients' clinicopathological characteristics were analyzed and adjuvant treatment suggestions from MDT were obtained. Here the chemotherapy decision alteration was defined as a disagreement in chemotherapy or not, or inconsistence in regimens between the attending doctor and the multidisciplinary team. Results: A total of 194 patients aged ≤70 years old were enrolled in the multidisciplinary discussion, and 187 patients (96.4%) were suggested to receive chemotherapy. When compared the opinions of the attending doctor to suggestions of the multidisciplinary team, we found that the percentage of chemotherapy decision alteration reached 22.7% (39/172), of which 94.9% (37/39) were inconsistence in chemotherapy regimens. There were 119 patients who were recommended to receive epirubicin plus cyclophosphamide (EC) followed by docetaxel (T) or weekly paclitaxel (wP) regimens. Before the announcement of results for the E1199 trial, EC-T accounted for 62.5% (55/88), and EC-wP accounted for 37.5% (33/88) for this group of patients. After that, the proportion of EC-T was decreased to 22.6% (7/31) and proportion of EC-wP increased to 77.4%(24/31) (P<0.001). In addition, a total of 20 patients were suggested to receive platinum based chemotherapy. The proportions were 9.3% in cases with invasive ductal carcinoma, and 33.3% in cases with metaplastic carcinoma, respectively (P=0.016). Conclusions: The adjuvant chemotherapy decision for TNBC patients is altered in 22.7% of the patients after MDT discussion. After the announcement of SABCS E1199 results, more patients are suggested to receive EC followed by weekly paclitaxel. There is a lack of detailed evidence for platinum based adjuvant chemotherapy for TNBC, and more patients with metaplastic carcinoma receive platinum based adjuvant chemotherapy.

Abstract
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles for each of six 2.9 GW_{th} reactor cores at the Daya Bay and Ling Ao nuclear power plants. Using detector data spanning effective ^{239}Pu fission fractions F_{239} from 0.25 to 0.35, Daya Bay measures an average IBD yield σ[over ¯]_{f} of (5.90±0.13)×10^{-43} cm^{2}/fission and a fuel-dependent variation in the IBD yield, dσ_{f}/dF_{239}, of (-1.86±0.18)×10^{-43} cm^{2}/fission. This observation rejects the hypothesis of a constant antineutrino flux as a function of the ^{239}Pu fission fraction at 10 standard deviations. The variation in IBD yield is found to be energy dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the evolution in the IBD spectrum show general agreement with predictions from recent reactor models, the measured evolution in total IBD yield disagrees with recent predictions at 3.1σ. This discrepancy indicates that an overall deficit in the measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes ^{235}U, ^{239}Pu, ^{238}U, and ^{241}Pu. Based on measured IBD yield variations, yields of (6.17±0.17) and (4.27±0.26)×10^{-43} cm^{2}/fission have been determined for the two dominant fission parent isotopes ^{235}U and ^{239}Pu. A 7.8% discrepancy between the observed and predicted ^{235}U yields suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Abstract
Objective: The aim of this study was to analyze the trend of incidence, clinicopathological characteristics and therapy of young (less than 40 years old) patients with advanced lung adenocarcinoma, and to identify the prognostic factors. Methods: The clinical data of 198 young patients with advanced lung adenocarcinoma were collected from the Cancer hospital and Institute of Chinese academy of Medical Sciences from January 2001 to June 2012. To analyze the trend of incidence, clinicopathological characteristics and therapy and evaluate the independent prognostic factors affecting survival time with Cox proportional hazards model. Results: From 2001 to 2012, the incidence of lung adenocarcinoma in young patients was increased year by year. Among the 198 patients, 92 were males and 106 were females. Their age was from 20 to 40 with a median age of 34 years. Most patients had poorly differentiated adenocarcinoma (46.7%) whereas 36.7% of the cases had moderately differentiated tumor. Among the 198 patients, there were 25 patients with stage ⅢB (12.6%) and 173 (87.4%) cases of stage Ⅳ cancer.The 1-, 3- and 5-year survival rates were 70.7%, 21.6% and 10.3%, respectively. Among the198 cases, patients who received epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy, the median OS (25.6 months) was significantly longer than that of patients who never received EGFR-TKI therapy (13.3 months)(P<0.001). Since 2009, the number of cases detected for EGFR gene was gradually increased, and the median OS of patients diagnosed from 2010 to 2012 was 22 months, significantly higher than that of 16 months of patients diagnosed during 2001-2009 (P=0.019). The Cox regression analysis showed that the performance status, extra-pulmonary metastasis and whether received EGFR-TKI therapy were independent prognostic factors. Conclusions: The incidence rate of lung adenocarcinoma in young patients has an increasing trend. They have a high proportion of women and of poor differentiation. The patients can get benefits from EGFR-TKI therapy. Mutivariate Cox regression analysis shows that the performance status, extra-pulmonary metastasis and whether received EGFR-TKI therapy are independent prognostic factors for young patients with advanced lung adenocarcinoma.

Abstract
Aglossia is a rare congenital abnormality, often associated with micrognathia and limb defects. Situs inversus totalis is also a rare congenital abnormality, defined as a mirror-image reversal of all the asymmetric organs of the thorax and abdomen. The concurrence of these two abnormalities has only been reported in eight similar cases in the literature. Although micrognathia and malocclusion were observed in all of these cases, few treatments were performed for the patients' dentofacial deformities. This report describes the case of a 7-year-old boy suffering from micrognathia, aglossia, and situs inversus totalis simultaneously, and the treatment for his micrognathia by mandibular symphyseal midline distraction osteogenesis, guided by virtual surgical planning and a three-dimensional printed surgical template. In a review of the literature, this is the first case of micrognathia associated with aglossia and situs inversus totalis that has been treated by mandibular symphyseal midline distraction osteogenesis for the dentofacial deformity.

Abstract
Many studies measure the same type of information longitudinally on the same subject at multiple time points, and clustering of such functional data has many important applications. We propose a novel and easy method to implement dissimilarity measure for functional data clustering based on smoothing splines and smoothing parameter commutation. This method handles data observed at regular or irregular time points in the same way. We measure the dissimilarity between subjects based on varying curve estimates with pairwise commutation of smoothing parameters. The intuition is that smoothing parameters of smoothing splines reflect the inverse of the signal-to-noise ratios and that when applying an identical smoothing parameter the smoothed curves for two similar subjects are expected to be close. Our method takes into account the estimation uncertainty using smoothing parameter commutation and is not strongly affected by outliers. It can also be used for outlier detection. The effectiveness of our proposal is shown by simulations comparing it to other dissimilarity measures and by a real application to methadone dosage maintenance levels.

Abstract
BACKGROUND Intermittent parathyroid hormone (PTH) can be used to treat osteoporosis of the spine and hip. However, whether it can be used to treat osteoporosis of the mandible is unclear. The purpose of this study was to explore the influence of applying intermittent PTH to ovariectomized rats on the trabecular bone microarchitecture of the mandible and femoral head. METHODS Eighteen female rats were divided into three groups: the healthy group, ovariectomized (OVX) group, and OVX + PTH group. The OVX group and OVX + PTH group had an OVX at 8 weeks of age. The OVX + PTH group received intermittent PTH therapy for 12 weeks. The mandibles and femurs of all rats were removed at 20 weeks and were then scanned using microcomputed tomography (micro-CT). RESULTS From the micro-CT analysis, the trabecular bone microarchitecture of the mandible and femoral head are offered as follows: (1) The bone volume fraction and trabecular thickness in the OVX group were lower than those in the healthy group. (2) The bone volume fraction and trabecular thickness in the OVX + PTH group approximated those in the healthy group. CONCLUSION The conclusions of this study regarding the trabecular bone microarchitecture of the mandible and femoral head are offered as follows: (1) The BV/TV and TbTh in the OVX group were lower than those in the healthy group. (2) The BV/TV and TbTh in the OVX + PTH group approximated those in the healthy group, therefore, intermittent PTH displayed high efficacy for treating femoral or mandibular deterioration of bone microstructure resulting from loss of ovarian function. Osteoporosis of the femur or mandible in the rats was ameliorated by intermittent PTH therapy.

Abstract
OBJECTIVE To investigate the characteristics and outcomes of necrotizing enterocolitis (NEC) in Chinese term infants population. METHODS A national neonatal necrotizing enterocolitis network was established. Neonates as having necrotizing enterocolitis with gestation age ≥37 weeks were identified if they met the accepted diagnostic criterion during the study period from Jan 1(st) 2011 to Dec 31(st) 2011. The data of maternal and neonates' characteristics, the comorbidities, the clinical interventions prior to NEC, the clinical courses and radiology results, the medical and surgical treatment and the outcomes were collected. SPSS 19.0 software was used to do statistic analysis. Logistic-regression models were used to analyze the risk factors for death in infants with NEC, odds ratio (OR) and 95% confidence interval (CI) were calculated. RESULTS There were 231 067 newborn infants, 164 307 of them were term infants, admitted to 95 hospitals in main land China. There were 718 term infants were diagnosed as necrotizing enterocolitis with the incidence of 0.44%. There were 294 term infants cases identified as ≥stage 2 necrotizing enterocolitis for the analysis, including 193 cases of stage 2 and 101 cases of stage 3.The mean gestation age was (39.0±1.3) weeks, and the mean birth weight was(3 087.4±548.3)g. The percentage of small for gestation age was 20.4%. The onset age of NEC was 5 (2-11)d. The percentage of cases received breast milk feeding was 23.7%. The most common comorbidities were sepsis (9.5%, 28/294), asphyxia (9.5%, 28/294), pneumonia (7.8%, 23/294) and congenital megacolon (7.5%, 22/294). The bowel perforation rate was 13.9%. The rate of cases who received surgical treatment was 25.2%(76.6% small intestinal necrosis and 65.8% small intestinal perforation). The mortality rate was 28.9%(the mortality rate were 20.7% and 44.6% in stage 2 and stage 3 NEC, respectively). Noninvasive continuous positive airway pressure treatment for NEC (OR=5.278, 95% CI: 2.058-13.533, P<0.01) and NEC staging 3 (OR=3.156, 95% CI: 1.766-5.642, P<0.01) were statistically significantly associated with mortality of NEC. CONCLUSIONS The term infants with necrotizing enterocolitis usually have the underlying comorbidities. The breastmilk feeding rate is low. Necrotizing enterocolitis remains high mortality in term neonates in Chinese neonatal units. Noninvasive continuous positive airway pressure treatment for NEC is statistically significantly associated with mortality of NEC.

Abstract
OBJECTIVE To identify the sensitive scales and the early change of nerve conduction for chronic oxaliplatin-induced peripheral neuropathy (OXLIPN), and to investigate correlation between the symptoms of acute OXLIPN and chronic OXLIPN. METHODS Between December 2014 and August 2015, 16 colorectal cancer patients confirmed by pathology, from department of Oncology, Chinese PLA General Hospital, scheduled to receive XELOX, completed the acute neurotoxic symptoms questionnaire at the end of 1 cycles and the scales of TNSc and NCI-CTC at the baseline and the end of 4 cycles. Nerve conduction studies (bilateral peroneal nerves and sural nerves) were performed in 11 patients at the baseline and the end of 4 cycles. RESULTS After chemotherapy, TNSc increased 1-9 points for all cases, while NCI-CTC increased 1 point for only 9 cases, the remaining 7 cases had the same NCI-CTC score before and after chemotherapy, where TNSc increased 1-6 points. Left sural nerve a-SNAP (amplitude of sensory nerve action potential) was (15.3±5.8)μV before chemotherapy and(12.3±5.0)μV after chemotherapy. Right sural nerve a-SNAP was (17.4±8.6)μV before chemotherapy and (13.3±6.7)μV after chemotherapy. After chemotherapy, these datum were significantly reduced for left peroneal nerve distal and proximal a-CMAP (amplitude of compound muscle action potential), bilateral sural nerve a-SNAP and left sural nerve SCV (sensory conduction velocity) (P<0.05). After chemotherapy, TNSc was correlated significantly with the acute neurotoxic symptoms questionnaire (Spearman r=0.698, P=0.003). CONCLUSIONS TNSc is more sensitive to the severity and changes in chronic OXLIPN than NCI-CTC. Sural nerve a-SNAP has a higher sensitivity for the early changes of nerve conduction studies in chronic OXLIPN. Patients who have more symptoms of acute OXLIPN are those who eventually develop more severe chronic OXLIPN.

Abstract
The study reports a girl with pyridoxine-dependent epilepsy. The girl was admitted at the age of 2 years because of intermittent convulsions for 1.5 years and psychomotor retardation. She had a history of "hypoxia" in the neonatal period. At the age of 5 months recurrent epileptic seizures occurred. The child was resistant to antiepileptic drugs, and had many more seizures when she got cold or fever. She also had a lot of convulsive status epilepticus. No discharges were found during several video-EEG monitorings. Cerebral MRI examinations showed normal results. So Dravet syndrome was clinically suspected. ALDH7N1 gene mutation analysis revealed two heterozygote mutations, and pyridoxine-dependent epilepsy was thus confirmed. Seizures were generally controlled after pyridoxine supplementation.
