Abstract
Objective:This study was to analyze the results of video head impulse test (vHIT) of benign paroxysmal vertigo of childhood (BPVC) in order to determine the potential value of vHIT in the diagnosis and treatment for BPVC and to discuss its possible pathogenesis of BPVC. Method:Thirty-six children with BPVC were enrolled. No hearing loss and skull abnormality were found in these children as assessed by pure tone audiometry, acoustic impedance, CT or MRI scan. The vHIT was carried out, and main outcome measures were the gain of vestibulo-ocular reflex, gain asymmetry, and refixation saccades. Eleven healthy children were selected as normal control who came to our hospital for doing a routine checkup and have no history of dizziness. The differences of vHIT results between these two groups were analyzed. Result:①The vHIT results in control group were normal. In all BPVC subjects, abnormalities were detected in 9 patients (25.0%),including vHIT gains decline in 3 patients, abnormal symmetry in 4 patients, and abnormal isolated overt saccades in 2 patients.②The average saccadic gain in different canals of BPVC group was 1.03±0.14, 1.01±0.15, 1.13±0.31, 1.18±0.36, 1.21±0.33, 1.14±0.30 in left horizontal, right horizontal, left anterior, right posterior, right anterior, left posterior canal, respectively; while in normal group, it was 1.14±0.15, 1.18±0.09, 1.16±0.30, 1.18±0.40, 1.34±0.26, 1.30±0.20, respectively. Significant statistical difference was found only in horizontal canals between these two groups (P<0.05). ③Asymmetry of the three pairs of conjugated semicircular canals was 0.04±0.07 (horizontal canal), 0.06±0.04 (left anterior and right posterior canal), 0.06±0.04 (right anterior and left posterior canal) in BPVC group, respectively; while in control group, it was 0.02±0.02, 0.04±0.03, 0.04±0.04,respectively. There was no statistical difference between the two groups (P>0.05). Conclusion:A certain proportion of abnormal peripheral vestibule function in children with BPVC was found. vHIT is a "child friendly," relatively easytouse, and simple tool to evaluate each of the 6 semicircular canals, which may offer some potential clinical information for assessing the vestibule dysfunction for BPVC.

Abstract
Objective: To analyze the incidence and influencing factors of venous thromboembolism (VTE) after lung transplantation. Methods: This study retrospectively analyzed the clinical data of 375 lung transplant patients from January 2015 to December 2017 in Wuxi People's Hospital. Every patient was classified into the VTE group or the non-VTE group according to whether the patient had VTE or not. Basic information like age, type of surgical procedure etc. was compared between two groups. The prevention and treatment of VTE between two groups were also compared. Furthermore, multivariate Logistic regression analysis was used to analyze the influence of related factors on the occurrence of postoperative VTE. Deep venous thrombosis (DVT) was diagnosed with vascular ultrasonography, and pulmonary thromboembolism (PTE) was diagnosed with CT pulmonary angiogram, nuclear ventilation/perfusion scanning, or pulmonary angiography. Results: This study included 316 lung transplant patients. VTE occurred in 19 patients (6.0%) during perioperative and follow-up period. The age of the VTE group was significantly higher than that of the non-VTE group (63.4±11.9 vs 54.3±13.0, P=0.003). The proportion of single lung transplantation in the VTE group was significantly higher than that in the non-VTE group (78.9% vs 48.5%, P=0.010). The incidence of VTE in patients without prevention was significantly higher than that in patients with prevention (15.0% vs 1.9%, P<0.001). Single lung transplantation (OR=4.425, P=0.018), duration in intensive care unit (ICU) (OR=1.396, P=0.001) and age (OR=1.080, P=0.005) were independent risk factors for VTE after lung transplantation. Conclusions: The incidence of VTE after lung transplantation is high. Single lung transplantation, prolonged duration of ICU stay and advanced age increase the risk of VTE after lung transplantation.

Abstract
Objective: To discuss the benefit of using transmastoid slotted labyrinthotomy approach (TSLA) and customized electrode for common cavity deformity (CCD) patients, and to evaluate the audiological outcomes. Methods: A retrospective analysis of the intraoperative monitoring data and postoperative auditory outcomes of 10 CCD cases who received cochlear implantation in Beijing Tongren Hospital,Capital Medical University from April 2016 to December 2017, was conducted using TSLA and customized electrod as a test group.At the same time, 10 cases of age and gender matched children with severe or severe sensorineural hearing loss and normal inner ear structures were recorded as a control group. Four questionnaires were collected from the two groupspre-operative, 6 months and 1 year after start-up. The Wilcoxon signed rank sum test was used to compare the scores of different time points. Rank sum test of two independent samples was used to compare the scores between different groups. Results: None of the patients exhibited CSF leakage or facial paralysis after operation. The average impedance of 8 CCD children in the experimental group was below 5 kΩ. The total extraction rate of auditory neural response telemetry (ART) of all stimulating electrodes was 55% (33/60), and the amplitude of the electricity induced complex action potential (ECAP) of electrodes at different positions ranged from 50.69 to 170.3 μV.The average surgical time of the TSLA group was 46.4 min, shorter than the traditional approach.There was significant difference between the scores of pre-operative, 6 months and 1 year after start-up for the TSLA group(categories of auditory performance,CAP: 2.0 (2.0,3.0) vs. 4.0 (3.8,4.0) , Z=-3.109, P=0.002; speech intelligibility rating,SIR: 2.0 (2.0,2.3) vs. 3.0 (2.8,4.0) , Z=-2.952, P=0.003; meaningful use of speech scale,MUSS: 4.0 (3.3,6.0) vs. 9.0 (6.0,11.8) , Z=-3.421, P=0.001; meaningful auditory integration scale, MAIS or infant-toddler and meaningful auditory integration scale, IT-MAIS: 5.5 (3.8,9.0) vs. 15.5 (10.8,18.5) , Z=-3.522, P=0.000 for the latter two).In addition, The scores of the TSLA group were significantly worse than the control group at 6 months and 1 year after start-up.The high-resolution CT scan showed good adhesion of the electrodes without displacementone week and one year after surgery. Conclusions: For CCD patients, TSLA and customized electrode is recommended due to lower surgical difficulty and post-operative risk, shortened surgical time; Intraoperative ART monitoring can be used to determine the integrity of the auditory pathway. Children with common cavity deformity have a longer period of auditory rehabilitation, and the individual differences in speech rehabilitation are significantly different, which is significantly worse than those with normal structure.

Abstract
Objective: To investigate the relationship between the previous cesarean scar thickness, previous cesarean scar defect and the occurrence of uterine rupture for pregnancy women after previous cesarean section and to predict the occurrence of uterine rupture in the third trimester for pregnancy women after previous cesarean section by analyzing the lower uterine segment (LUS) situation or quantitatively measure LUS myometrium thickness. Methods: A total of 154 pregnant women who have a prior cesarean from January 2015 to March 2016 were selected, all of them regularly did the prenatal examination in the pregnancy period and finally gave birth in hospital. By the transvaginal sonograph, the LUS myometrium thickness (transverse and longitudinal thickness) and the size of the previous cesarean scar defect were measured in the first trimester, the LUS myometrium thickness (longitudinal thickness) and qualitatively analysis LUS condition were measured in the third trimester. They were divided into two groups according to the pregnancy outcome: uterine rupture group (found in the cesarean operation or during the pregnancy) and without uterine rupture group (including the vaginal delivery women and those without uterine rupture in the cesarean operation period). The sensitivity and specificity of LUS myometrium thickness in the first trimester and the qualitative analysis LUS situation, the quantitative measurement of LUS myometrium thickness in the third trimester were compared in the prediction of occurrence of uterine rupture (dehiscence or complete rupture). Results: The group without uterine rupture included 134 women (6 vaginal delivery and 128 cesarean delivery), and the group with uterine rupture included 20 women (all of them cesarean delivery). The LUS myometrium thickness in the third trimester in the group without uterine rupture was (1.6±0.5) mm, and was (1.1±0.7) mm in the uterine rupture group (P= 0.004). There were no significant difference between two groups in the mean value of age, height, weight, the interdelivery interval, the LUS myometrium thickness (transverse and longitudinal thickness) in the first trimester. Qualitative analysis of LUS condition had higher specificity (99%), higher positive predictive value (92%), higher negative predictive value (94%) and slightly lower sensitivity (60%) than quantitative measure of LUS myometrium thickness in predicting uterine rupture. Conclusions: Measurement of the LUS myometrium thickness in the first trimester is helpful for predicting the occurrence of uterine rupture, so it is not necessary to terminate the pregnancy because of the thin LUS or the little prior cesarean scar defect in the first trimester. However it should be paid close attention to the LUS situation during the whole gestation. Qualitatively analyzing LUS situation is more meaningful than quantitatively measuring LUS myometrium thickness in predicting the uterine rupture in the third trimester.

Abstract
Objective: To evaluate the outcomes of trabeculectomy combined with a new prophylactic sclerotomy in late stage juvenile open angle glaucoma (JOAG) and primary congenital glaucoma (PCG) patients at high risks of intraoperative and postoperative suprachoroidal hemorrhage (SCH). Method: A retrospective case series study. Thirty-three eyes of 28 JOAG patients and 15 eyes of 12 PCG patients with high risk factors for severe choroidal effusion or SCH were enrolled from November 2006 to April 2012 at Eye and ENT Hospital of Fudan University. The standard trabeculectomy accompanied by prophylactic sclerotomy was performed (video attached). Ophthalmic examinations were performed before and after the surgery. Surgical outcome was assessed in terms of intraocular pressure (IOP), best-corrected visual acuity, optic nerve head cup disc ratio, visual field, and complications. All patients were followed up for at least 1 year. Complete success was defined as an IOP ≥6 mmHg (1 mmHg=0.133 kPa) but ≤18 mmHg without medication. Qualified success was defined as an IOP ≥6 mmHg but ≤18 mmHg with local application of medications. Kaplan-Meier survival curves were drawn for the success rate calculation. Results: The mean age of all 40 patients was (13.2±9.4) years old. And among them, 22 patients were male and 18 patients were female. The mean follow-up time was (31.8±15.9) months. At the postoperative 3(rd) year, the complete success rate was 75.8%, and the qualified success rate was 90.0%. In our case series, one eye had expulsive SCH intraoperatively and two eyes had delayed SCH postoperatively. All of them were successfully saved without further surgery and with no significant damage to visual function. Conclusion: Trabeculectomy combined with prophylactic sclerotomy is a promising technique developed to control IOP in late stage JOAG and PCG patients, which provides a potential intervention to reduce severe consequences of massive choroidal effusion or SCH.

Abstract
Objective: To observe the efficacy and safety of de novo combination of Lamivudine(LAM) and Adefovir Dipivoxil (ADV) therapy counter to Entecavir (ETV) monotherapy in patients with chronic hepatitis B (CHB)- related compensated liver cirrhosis. Methods: Patients with chronic hepatitis B-related compensated cirrhosis who were initially treated with LAM and ADV for more than 1 year were randomly assigned to two groups, one half replaced with ETV monotherapy, and the other half continued LAM and ADV co-therapy. Liver biochemistry, renal biochemistry, estimated glomerular filtration rate, alpha-fetoprotein, HBV serology markers and serum HBV DNA were measured every 3 months. Urine β2-microglobulin was measured every 6 months And retinol binding protein, followed up for 3 years. The mean values of the two groups were compared with t-test, and the rate of comparison was analyzed by x2 test. Results: A total of 580 cases were collected, 290 cases were replaced with ETV monotherapy, the other 290 patients continued to LAM and ADV combination therapy. In the ETV group, the rates of HBV DNA negative conversion at 1 year, 2 years and 3 years were 77.6%, 84.5% and 94.5% respectively, while the HBV DNA negative conversion rates at 1, 2 and 3 years in the LAM and ADV combination groups were 69.3%, 73.4% and 80.3% respectively. Among them, the negative rates of HBV DNA in the second year and the third year were P < 0.05, the difference was statistically significant. The 3-year cumulative gene-resistant rate in the ETV group was 1.4%, while the combined treatment was as high as 8.6%, and the difference was statistically significant in the two groups. The estimated value of serum creatinine and glomerular filtration rate in ETV group was followed by 3 years, and the baseline level was maintained, in the same group, the serum creatinine was higher than baseline, and the estimated value of glomerular filtration rate decreased. The results showed that there were 6.2%, 12.1%, 22.1% and 0, 0.3%, 1%, respectively, in 1, 2 and 3 years for the group of consecutive treatment and the replacement of ETV Group. The estimated glomerular filtration rate decreased by more than 30% compared with the baseline. The difference was statistically significant; the proportion of serum creatinine in the 1 year, 2 years and 3 years of the combined treatment group was 1.7%, 4.5% and 6.6%, compared with the baseline rise of > 50 μmol/l, and the ETV group was replaced in the 1 year, The values of 2 and 3 years were 0,0,0.7%, of which the 2nd and 3rd years were statistically significant; the proportion of microalbuminuria and retinol-binding protein in patients with combined treatment group was also significantly higher than that of Β2-m ETV Group. Conclusion: The initial combination of LAM and ADV therapy is inferior in terms of ETV monotherapy. Single therapy with ETV increase the rate of viral response, reduce the incidence of drug resistance, and also reduce the incidence of renal impairment in patients with chronic hepatitis B -related compensated liver cirrhosis.

Abstract
Objective: To investigate the role of neutrophil elastase inhibitor, sivelestat, in preventing and treating nonalcoholic steatohepatitis (NASH) and its underling mechanisms. Methods: A total of forty 4-week-old male C57BL/6J ApoE-/-mice were equally divided into the following four groups: standard chow (SC)+isotonic saline; SC+sivelestat; high-fat, high-cholesterol (HFHC) diet+isotonic saline; and HFHC+sivelestat. These mice were treated with above methods for 12 weeks. Blood and liver tissue samples were collected to measure biochemical parameters, hepatic steatosis and non-alcoholic fatty liver disease (NAFLD) activity score (inflammation) were evaluated by oil red O staining and HE staining, respectively. The mRNA and protein expression levels of hepatic inflammatory cytokines, CD68, and F4/80 were determined by quantitative RT-PCR and immunohistochemistry, respectively. Comparison of means between the four groups was made by one-way analysis of variance, and comparison between any two groups was made by the LSD or SNK method (for data with homogeneity of variance) or the Tamhane or Dunnett method (for data with heterogeneity of variance). Results: Mice fed with an HFHC diet for 12 weeks developed typical pathological features of NASH compared with those fed with SC. Compared with mice fed with HFHC diet without sivelestat, those treated with HFHC and sivelestat exhibited the following features: (1) significantly reduced fast blood glucose, blood cholesterol, and hepatic biochemical parameters, as well as increased insulin sensitivity; (2) significantly reduced NAFLD activity score (5.71±1.11 vs 3.16±1.16, P < 0.05); (3) reduced monocyte chemoattractant protein-1 and tumor necrosis factor -α; (4) significantly reduced mRNA levels of CD68 and F4/80; and (5) reduced expression of CD68 in the liver. Conclusion: Sivelestat alleviates the hepatic steatosis and inflammation of NASH in mice by inhibiting the activation of Kupffer cells.

Abstract
Objective: To explore the effects of menopausal factor on fine anatomy of bladder, urethra and vagina in women undergoing vaginal delivery. Methods: Gynecological patients in Nanfang hospital from January 2013 to October 2016 were collected, and then the patients whose MRI images quality meet the require of reconstruction, with the history of vaginal delivery experience, without any cesarean section experience, and the first labor time was ≤30 years old were enrolled. The patients who had pelvic floor dysfunction when done MRI examinations were excluded. Finally, 238 cases were randomly selected out, and 238 models of data were reconstructed and measured by Mimics and UG software. The independent t test was used to do the comparison between menopausal group and those not yet menopause. Results: First, we built 238 3D models totally. Second, the parameters related with bladder and urethra: the angle of bladder and urethra, β angle, urethra pubic angle, α angle, retropubic space, the length between bladder neck and edge of pubic midpoint, and urethral striated muscle thickness of menopausal group were bigger than those of pre-menopausal group. While for the urethra tilt angle, the former group was smaller than that of the latter group. But there was no significant statistical differences between two groups. Third, the parameters related with vagina: the proximal urethral vaginal gap of the post-menopause group was smaller than that of pre-menopausal group, while for the middle and distal urethral vaginal gap, the former group was bigger than that of the latter group. The length and width of vaginal anterior wall of the post-menopausal group were smaller than those of pre-menopausal group. Beside the middle urethral vaginal gap, all the difference between two groups had no statistical meaning. The 2D shape of axial vaginal, H type occupation of the former group was obviously lower than that of the latter group. Conclusions: Menopause has an effect on fine anatomy of pelvic organ. Especially on the shape of vagina, the middle urethral vaginal gap become much wider after menopause, the occupation of shallow concave type become much higher post-menopausal. It means the lateral and backward support function of the urethra and vagina is relatively weakened after menopausal, and the shape of vagina become smaller.

Abstract
Objective: To explore the correlation between ATP1A3 genotype and phenotype in children with alternating hemiplegia of childhood (AHC). Methods: This was a retrospective study. The clinical data and peripheral blood DNA of AHC patients were collected in Peking University First Hospital from August 2005 to December 2017. ATP1A3 gene mutations were screened by Sanger sequencing or next generation sequencing (NGS). AHC patients were divided into difference groups according to different hotspot mutations. SPSS 23.0 was used to analyze the correlation between genotype and phenotype. Variance analysis was used to compare the measurement data between groups. Chi square test was used to compare the categorical data between groups. Kruskal-Wallis test was used to compare the unidirectional ordered data between groups. Least-significant difference(LSD) was used to compare the data between two groups. Results: A total of 119 AHC patients were recruited, including 68 males and 51 females. The onset age of 113 (95.0%) patients was within 18 months. There were 119 cases (100.0%) with hemiplegic seizures, 109 cases (91.6%) with abnormal eyeball movements, 104 cases (87.4%) with dystonia, 31 cases (26.1%) with autonomic neurological symptoms, 31 cases (26.1%) with epileptic seizures and 117 cases (98.3%) with long-term developmental delay. In 113 patients (95.0%) with ATP1A3 gene mutations, 111 were de novo mutation and 2 were genetic mutations. A total of 39 mutation types were found, including 37 missense mutations and 2 deletion mutations. Seventeen of them were novel mutations. The three hotspot mutations were D801N (n=34, 30.1%), E815K (n=20, 17.7%) and G947R (n=13, 11.5%). The age of onset of D801N and E815K were earlier than G947R ((3.1±2.1)and (2.3±2.3)vs.(6.4±7.7) months, P=0.004 and 0.003). The age of first hemiplegic events of D801N and E815K were earlier than G947R((6.4±3.1) and (6.8±3.3) vs. (11.4±10.1) months, P=0.004 and 0.016). More patients with E815K mutations presented epilepsy than those with D801N (P=0.003) and G947R (P=0.001). More patients with E815K mutations presented greater motor and intellectual disability than the patients with D801N (P=0.001) and G947R mutations (P=0.001). Conclusions: ATP1A3 gene is the main causative gene of AHC. Three hotspot mutations, D801N, E815K and G947R, were found. Hotspot mutation E815K is associated with the most severe phenotype, which presented an earlier age at the time of the first paroxysmal manifestation and first hemiplegic event, severer developmental delay and a greater proportion of epilepsy.

Abstract
Fermented soybean meal (FSM), which has lower anti-nutritional factors and higher active enzyme, probiotic and oligosaccharide contents than its unfermented form, has been reported to improve the feeding value of soybean meal, and hence, the growth performance of piglets. However, whether FSM can affect the bacterial and metabolites in the large intestine of piglets remains unknown. This study supplemented wet-FSM (WFSM) or dry-FSM (DFSM) (5% dry matter basis) in the diet of piglets and investigated its effects on carbon and nitrogen metabolism in the piglets' large intestines. A total of 75 41-day-old Duroc×Landrace×Yorkshire piglets with an initial BW of 13.14±0.22 kg were used in a 4-week feeding trial. Our results showed that the average daily gain of piglets in the WFSM and DFSM groups increased by 27.08% and 14.58% and that the feed conversion ratio improved by 18.18% and 7.27%, respectively, compared with the control group. Data from the prediction gene function of Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) based on 16S ribosomal RNA (rRNA) sequencing showed that carbohydrate metabolism function families in the WFSM and DFSM groups increased by 3.46% and 2.68% and that the amino acid metabolism function families decreased by 1.74% and 0.82%, respectively, compared with the control group. These results were consistent with those of other metabolism studies, which showed that dietary supplementation with WFSM and DFSM increased the level of carbohydrate-related metabolites (e.g. 4-aminobutanoate, 5-aminopentanoate, lactic acid, mannitol, threitol and β-alanine) and decreased the levels of those related to protein catabolism (e.g. 1,3-diaminopropane, creatine, glycine and inosine). In conclusion, supplementation with the two forms of FSM improved growth performance, increased metabolites of carbohydrate and reduced metabolites of protein in the large intestine of piglets, and WFSM exhibited a stronger effect than DFSM.

Abstract
Objective: To summarize the clinical features of TBC1D24 gene mutations associated with epilepsy. Methods: All the patients with TBC1D24 gene compound heterozygous mutations were retrospectively collected at the Pediatric Department of Peking University First Hospital from March 2015 to July 2017, and the features of clinical manifestations, electroencephalogram, and neuroimaging were analyzed. Results: Eighteen cases with TBC1D24 gene compound heterozygous mutations were included. The age of seizure onset was 1 day to 8 months, and the median age was 90 days. Seizure types included generalized tonic-clonic seizures (GTCS) in 3 cases, focal seizures in 18 cases, myoclonus in 18 cases, and 17 cases had focal myoclonus and myoclonus status. The focal myoclonus involving one or multiple muscle groups, sometimes migrating and alternating, lasting up to minutes to several days, and could be terminated by sleep or sedation drugs. In 11 cases, myoclonus was exacerbated by fever or infections, and 2 cases developed into myoclonic status during infection, in a severe case with the loss of consciousness. The magnetic resonance imaging (MRI) of seven patients was abnormal, including cerebral atrophy or cerebellar atrophy with abnormal signals. Segment myoclonus was captured in 10 patients, but without correlated epileptiform discharges. There were ten cases had varying degrees of developmental delay, 7 were normal, and one patient died of status epilepticus at the age of 4 months. Three cases had hearing disorders. In the 18 patients, the clinical phenotype of 4 cases consisted of epilepsy of infancy with migrating focal seizures, 2 with progressive myoclonus epilepsies, 1 with Dravet syndrome, 1 with DOORS syndrome, and 3 with unclassified epileptic encephalopathy. Conclusions: The clinical feature of TBC1D24 gene mutation related epilepsy was focal myoclonus, and tended to develop into myoclonic status epilepticus, and could be aggravated by infections, and terminated by sleep or sedation drugs. Mental retardation involved or not, neuroimaging could present with cerebral atrophy or cerebellar atrophy with abnormal signals.

Abstract
Objective: To study the effect of lentivirus-mediated microRNA (miR) -1246 RNA interference (RNAi) on biological characteristics and behaviors in cervical cancer cells as well as to identify the downstream signaling pathways affected. Methods: MiR-1246 specific cDNA was synthesized and cloned into the recombinant lentiviral vector (LV-miR-1246-inhibitor) . The SiHa cells were devided into three groups: no viral infection (negative control, NC) , infection with control virus (LV-NC) , and infection with miR-1246-inhibitor virus (LV-miR-1246-inhibitor) . The expression of the miR-1246 was detected by reverse transcription (RT) -PCR. Cell growth was analyzed by cell counting kit 8 (CCK-8) assay. The invasion was dectected by transwell matrige gel. Cell apoptosis was detected by flow cytometer. The growth of xenograft tumors was also investigated. Expression of thrombospondin-2 (THBS2) , matrix metalloproteinase (MMP) 2, 9 were also evaluated in the cells. Results: (1) The expression level of miR-1246 in SiHa cells (0.11±0.13) was significantly lower in group LV-miR-1246-inhibitor than those in the group LV-NC and the group NC (1.14±0.86 and 1.30±0.73, respectively; P<0.01) . (2) The proliferation of SiHa was also markedly suppressed in CCK-8 at 96 hours (P<0.01) . (3) The number of group LV-miR-1246-inhibitor was significantly less than those in the LV-NC and NC groups in transwell invasion assay (71±4, 162±5 and 188±5, respectively; P<0.01) . (4) The apoptosis rate of SiHa cells in the group LV-miR-1246-inhibitor [ (16.10±3.37) %] was significantly lower than those of group LV-NC and group NC [ (5.67±0.89) % and (1.78±0.08) %,P<0.01]. (5) The tumor volume in the nude mice group LV-miR-1246-inhibitor [ (287±59) mm(3)] was significantly lower than those in the LV-NC and NC groups [ (571±137) and (657±144) mm(3), respectively; P<0.01]. (6) Compared with the LV-NC group and the NC group, THBS2 protein expression in the tumor tissue of the nude mice in the group LV-miR-1246-inhibitor was significantly increased (P<0.05) , while the expression levels of MMP-2 and MMP-9 protein were significantly decreased (P<0.01) . Conclusion: These results suggest that miR-1246 functions during cervical cancer pathogenesis and tumor formation via the THBS2, MMP signaling pathway.

Abstract
Objective: To investigate the effect of ubiquitous mitochondrial creatine kinase 1(CKMT1) on the sensitivity of human nasopharyngeal carcinoma cell line CNE-1 to DDP. Methods: CNE-1 cells were transiently transfected with CKMT1 overexpression (CKMT1) or empty vector (EV). The growth curve and DDP IC50 were developed by MTT assay, plate clone formation assay was performed by gradient concentration of DDP treatment, cell cycle and apoptosis were detected by flow cytometry, levels of apoptosis related protein Bax/Bcl-2/C-PARP and the transcription factor p-STAT3-Tyr705 were detected by Western Blot. Results: The transfection efficiencies of CKMT1 and EV were more than 90% with a higher proliferation rate in the CKMT1-transfected cells. However, the CKMT1-transfected cells had a DDP IC50 of 2.76 μmol/L, which was significantly lower than that of 4.60 μmol/L in the EV-transfected cells (P<0.01). With the treatment of certain concentration of DDP, the CKMT1-transfected cells had a lower clone formation rate, the cell cycle arrested more obviously in G2/M phase, and the apoptosis rate was higher (P<0.01), with higher levels of Bax/C-PARP (P<0.05 or P<0.01), but lower levels of Bcl-2 (P<0.01) and p-STAT3-Tyr705 (P<0.01), compare with the EV-transfected cells. Conclusions: CKMT1 may inhibit the activation of STAT3, increasing the sensitivity of CNE-1 to chemotherapeutic drug DDP.

Abstract
Objective: To explore the factors associated with illicit drug use (IDU) intention in secondary vocational school students based on theory of triadic influence (TTI), and provide theoretical foundation for IDU prevention education. Methods: A total of 8 870 students were selected from secondary vocational schools in 5 cities in China through multistage cluster sampling. A self-administered questionnaire was used to collect the information about students' sensation seeking (SS), parental monitoring (PM), perceived availability of drug (PAD), social benefit expectancies(SBE), refusal efficacy (RE) and social norms and IDU intention. Based on the TTI, the logistic regression model was used to analyze the factors associated with IDU. Results: Among the intrapersonal stream of influence, the higher levels of SS was the risk factor associated with IDU (OR=1.71, 95%CI: 1.22-2.41, P<0.01), medium RE level (OR=0.18, 95%CI: 0.14-0.23, P<0.001) and high RE level (OR=0.17, 95%CI: 0.13-0.22, P<0.001) were the protective factors for IDU intention. Among the interpersonal stream of influence, medium PM level (OR=0.46, 95%CI: 0.37- 0.56, P<0.001) and high PM level (OR=0.33, 95%CI: 0.24-0.46, P<0.001) were the protective factors for IDU intention, perceived others' drug use as well as perceived others' approval of substance use were risk factors for IDU intentions (P<0.001); Among sociocultural environmental stream of influence, perceived easy availability of drugs (OR=3.47, 95%CI: 2.69-4.48, P<0.001) and perceived SBE of drugs (OR=2.04, 95%CI: 1.69-2.46, P<0.001) were risk factors for IDU intentions (P<0.001). Conclusions: High levels of SS and SBE, perceived easier availability of substance, perceived others' substance use and perceived others' approval of substance use positively predict the students' intention of IDU. IDU prevention education for adolescents should be focused on the above factors, and parental supervision and students' refuse skills should be improved.

Abstract
Summary The prevalence of hearing loss in newborns and infants is estimated between 1 to 3.47 cases per 1000 live births. Neonatal screening for hearing loss and audiological evaluation are becoming more extensively carried out. However, there is no consensus regarding the use of audiometry and other electrophysiological tests in current practices. This article is intended to provide professionals with recommendations about the "best practice" based on consensus opinion of the session's speakers, and a review of the literature on the efficacy of various assessment options for children with hearing loss.

Abstract
AIMS Previous evidence has demonstrated that participation in the Dose Adjustment for Normal Eating (DAFNE) education programme can reduce HbA1c and severe hypoglycaemia in people with Type 1 diabetes. In a number of studies, increased HbA1c variability has been associated with higher diabetic morbidity and mortality. No studies have examined the impact of structured education on HbA1c variability in Type 1 diabetes. METHODS People with Type 1 diabetes who had attended DAFNE were identified for inclusion from the Scottish Care Information-Diabetes dataset. HbA1c median and variability, expressed as coefficient of variation (CV) before and after DAFNE was calculated. RESULTS Some 1061 individuals participated in DAFNE education and 687 met the inclusion criteria. A significant median reduction in HbA1c [-3.5 mmol/mol (-0.3%)] was seen at 12 months with a significant reduction [-1.5 mmol/mol (-0.1%)] still seen at 60 months of follow-up. HbA1c variability as measured by CV was significantly lower during the post-DAFNE period: 0.08 (IQR 0.05-0.12) reduced to 0.07 (IQR 0.05-0.10); P = 0.002. CONCLUSION The data confirm that DAFNE participation improves glycaemic control in Type 1 diabetes with benefits being sustained for 5 years. This study is the first to demonstrate reduced HbA1c variability after completion of structured education. This is new evidence of the beneficial impact of DAFNE on glycaemic profile.

Abstract
Differential cross sections and photon-beam asymmetries for the γ[over →]p→π^{-}Δ^{++}(1232) reaction have been measured for 0.7<cosθ_{π}^{c.m.}<1 and E_{γ}=1.5-2.95 GeV at SPring-8/LEPS. The first-ever high statistics cross-section data are obtained in this kinematical region, and the asymmetry data for 1.5<E_{γ}(GeV)<2.8 are obtained for the first time. This reaction has a unique feature for studying the production mechanisms of a pure uu[over ¯] quark pair in the final state from the proton. Although there is no distinct peak structure in the cross sections, a non-negligible excess over the theoretical predictions is observed at E_{γ}=1.5-1.8 GeV. The asymmetries are found to be negative in most of the present kinematical regions, suggesting the dominance of π exchange in the t channel. The negative asymmetries at forward meson production angles are different from the asymmetries previously measured for the photoproduction reactions producing a dd[over ¯] or an ss[over ¯] quark pair in the final state. Advanced theoretical models introducing nucleon resonances and additional unnatural-parity exchanges are needed to reproduce the present data.

Abstract
Aims This study investigated the influence of body mass index (BMI) on patients' function and quality of life ten years after total knee arthroplasty (TKA). Patients and Methods A total of 126 patients who underwent unilateral TKA in 2006 were prospectively included in this retrospective study. They were categorized into two groups based on BMI: < 30 kg/m2 (control) and ≥ 30 kg/m2 (obese). Functional outcome was assessed using the Knee Society Function Score (KSFS), Knee Society Knee Score (KSKS), and Oxford Knee Score (OKS). Quality of life was assessed using the Physical (PCS) and Mental Component Scores (MCS) of the 36-Item Short-Form Health Survey. Results Results Patients in the obese group underwent TKA at a younger age (mean, 63.0 years, sd 8.0) compared with the control group (mean, 65.6 years, sd 7.6; p = 0.03). Preoperatively, both groups had comparable functional and quality-of-life scores. Ten years postoperatively, the control group had significantly higher OKS and MCS compared with the obese group (OKS, mean 18 (sd 5) vs mean 22 (sd 10), p = 0.03; MCS, mean 56 (sd 10) vs mean 50 (sd 11), p = 0.01). After applying multiple linear regression with the various outcomes scores as dependent variables and age, gender, and Charlson Comorbidity Index as independent variables, there was a clear association between obesity and poorer outcome in KSFS, OKS, and MCS at ten years postoperatively (p < 0.01 in both KSFS and OKS, and p = 0.03 in MCS). Both groups had a high satisfaction rate (97.8% in the control group vs 87.9% in the obese group, p = 0.11) and fulfillment of expectations at ten years (98.9% in the control group vs 100% in the obese group, p = 0.32). Conclusion Although both obese and non-obese patients have significant improvements in function and quality of life postoperatively, obese patients tend to have smaller improvements in the OKS and MCS ten years postoperatively. It is important to counsel patients on the importance of weight management to achieve a more sustained outcome after TKA. Cite this article: Bone Joint J 2018;100-B:579-83.

Abstract
BACKGROUND Osteoporotic bone offers poor purchase for the instrumentation in patients with degenerative spinal deformity (DSD), which could lead to several complications. Recently, augmentation methods to improve pedicle screw fixation have been proposed. This retrospective study was to investigate the clinical and radiographic outcomes of expandable pedicle screws (EPS) in patients with osteoporotic DSD. HYPOTHESIS Expandable pedicle screws (EPS) provide excellent instrument fixation in patients with osteoporotic DSD, improving radiographic and clinical outcomes. MATERIALS AND METHODS A total of 27 (6 males and 21 females) DSD patients who underwent orthopedics operation with EPS were retrospectively studied. Full-length standing spinal radiographs were obtained in all patients pre- and postoperatively and again at the two-year follow-up. The functional evaluations before operation and at two-year follow-up were graded with Scoliosis Research Society outcomes instrument-22 (SRS-22) and Oswestry Disability Index (ODI) scoring system. RESULTS All patients obtained good corrective outcomes on spinal deformity. The preoperative ODI score was 36.7% and reduced to 11.9% at two-year follow-up (p=0.0000). Before operation, the SRS-22 function, pain, appearance and mental scores were 2.7±0.4, 3±0.6, 2.7±0.5 and 2.9±0.6, respectively. The scores at two-year follow-up were significantly improved to 3.8±0.7, 4.2±0.6, 4.3±0.6 and 4.4±0.7, respectively (p=0.0000). The SRS-22 satisfaction score was 4.6±0.4 at two-year follow-up. No instances of screw breakage, loosening or pullout in any patient at follow-up. DISCUSSION EPS provides excellent instrument fixation in patients with osteoporotic DSD, improving radiographic and clinical outcomes at two years' follow-up. TYPE OF STUDY Retrospective case series study. LEVEL OF EVIDENCE IV.

Abstract
Nasopharyngeal carcinoma (NPC) is a squamous cell carcinoma derived from the epithelium of the post-nasal cavity, with a unique geographic and ethnic distribution. Epstein–Barr virus (EBV) is an etiological agent of NPC, but how it contributes to carcinogenesis is not completely clear. Although it is thought that EBV latency participates in the development of NPC, increasing evidence reveals that the lytic cycle also plays an important role in the carcinogenic process. In this review, we summarize our recent studies on how EBV reactivation causes genomic instability and accelerates tumorigenesis in epithelial cells. The roles of three lytic genes, namely, BRLF1, BGLF5 and BALF3, in this process are also introduced. Moreover, blocking EBV reactivation using natural compounds may help delay the progression of NPC tumorigenesis. These studies provide a new insight into NPC carcinogenesis and raise the possibility that inhibition of EBV reactivation may be a novel approach to prevent the relapse of NPC.
