Abstract
During the COVID-19 pandemic, a series of non-pharmaceutical interventions, which were implemented to curb the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), significantly modified the seasonal pattern of influenza. The intensity of influenza activity markedly decreased and B/Yamagata lineage was no longer detected. As the national influenza sentinel surveillance data shown, clear seasonal patterns were observed for influenza between 2012-2019, annually with an average of 14.57% of specimens tested positive for influenza virus. However, the seasonal pattern of influenza was disrupted after the outbreak of COVID-19. In the 2020-2021 season, influenza demonstrated an extremely low activity (yearly positivity rate<1.0%), followed by a resurgence of winter peak in the 2021-2022 season. Following the downgrade of management of COVID-19 to Class B in China in December 26, 2022, social activities gradually resumed, leading to the rebound of influenza activity with an out-of-season ciculation. After COVID-19 pademic, other respiratory infectious diseases caused by SARS-CoV-2, respiratory syncytial virus, and mycoplasma pneumonia were alternatively or concurrently circulated with influenza. The prevention and control of influenza and other respiratory infectious diseases emphasizes a multi-disease prevention strategy, including long-term and continuous monitoring the epidemic trends in influenza virus and SARS-CoV-2, promoting influenza and COVID-19 vaccination among key populations, and strengthening the knowledge and public awareness of prevention and control for respiratory infectious diseases, etc.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
Objective: To evaluate the performance of the influenza surveillance network and compare the epidemic intensity of influenza during 2014-2020 in Shanghai. Methods: Based on the weekly reports of influenza-like illness (ILI) and laboratory-confirmed influenza cases from January 1, 2014 to December 31, 2020. This study first evaluated the data reporting and specimen collection of ILI cases for each sentinel hospital, and then calculated the percentage of ILI (ILI%), the proportion of specimens tested positive for influenza, and the incidence of influenza among all ILI outpatient and emergency visits to measure the epidemic intensity of influenza. Finally, seasonal autoregressive integrated moving average (ARIMA) model was applied to quantify the changes in epidemic intensity of influenza in 2020. Results: The proportion of influenza surveillance sentinel hospitals with a score of less than 5 in the evaluation of ILI data reporting and samples collection were 9.68% and 21.05% in 2020 in Shanghai, respectively. ILI% was estimated to be 1.51% (95%CI: 1.50%-1.51%) and 2.31% (95%CI: 2.30%-2.32%), respectively for 2014-2019 and 2020; the proportion of specimens tested positive was 24.27% (95%CI: 24.02%- 24.51%) and 7.15% (95%CI: 6.78%-7.54%), respectively; and the incidence of influenza was 3.66‰ (95%CI: 3.62‰-3.70‰) and 1.65‰ (95%CI: 1.57‰-1.74‰), respectively. ARIMA model showed that ILI% was increased by 45.25% in 2020 in Shanghai, and the proportion of specimens tested positive and the incidence of influenza were reduced by 78.45% and 51.80%, respectively. Conclusions: In 2020, the performance of influenza surveillance system has changed, ILI% has increased, the proportion of specimens tested positive and the incidence of influenza has decreased in Shanghai. The change in the quality of influenza surveillance is also a potential factor affecting the epidemic intensity of influenza. In the future, the quality control of influenza surveillance network still needs to be further strengthened.

Abstract
BACKGROUND Glucocorticoid modulatory element-binding protein 1 (GMEB1), which has been identified as a transcription factor, is a protein widely expressed in various tissues. Reportedly, the dysregulation of GMEB1 is linked to the genesis and development of multiple cancers.
AIM To explore GMEB1’s biological functions in hepatocellular carcinoma (HCC) and figuring out the molecular mechanism.
METHODS GMEB1 expression in HCC tissues was analyzed employing the StarBase database. Immunohistochemical staining, Western blotting and quantitative real-time PCR were conducted to examine GMEB1 and Yes-associate protein 1 (YAP1) expression in HCC cells and tissues. Cell counting kit-8 assay, Transwell assay and flow cytometry were utilized to examine HCC cell proliferation, migration, invasion and apoptosis, respectively. The JASPAR database was employed for predicting the binding site of GMEB1 with YAP1 promoter. Dual-luciferase reporter gene assay and chromatin immunoprecipitation-qPCR were conducted to verify the binding relationship of GMEB1 with YAP1 promoter region.
RESULTS GMEB1 was up-regulated in HCC cells and tissues, and GMEB1 expression was correlated to the tumor size and TNM stage of HCC patients. GMEB1 overexpression facilitated HCC cell multiplication, migration, and invasion, and suppressed the apoptosis, whereas GMEB1 knockdown had the opposite effects. GMEB1 bound to YAP1 promoter region and positively regulated YAP1 expression in HCC cells.
CONCLUSION GMEB1 facilitates HCC malignant proliferation and metastasis by promoting the transcription of the YAP1 promoter region.

Abstract
Objective: To predict the protection probability of different clinical outcomes after reinfection with Omicron variant in symptomatic and unvaccinated COVID-19 patients who infected with prototype strain. Methods: The data used in this study were derived from a systematic review and meta-analysis which systematically searched PubMed, Embase, Web of Science, and Europe PMC databases, included published and uploaded studies of dynamic changes of neutralizing antibodies in symptomatic COVID-19 patients from 1 January 2020 to 2 October 2022 and extracted the literature information, study design, serological experiment information and antibody results. According to the scatter distribution characteristics of antibody titer data, a generalized additive model based on Gaussian distribution was used to fit the titer value of neutralizing antibody based on logarithmic conversion and the dynamic change pattern of neutralizing antibody in symptomatic and unvaccinated COVID-19 patients infected with prototype strain over time was obtained. In this study, the fitted antibody titers of patients on the 28th, 51st, and 261st day after symptom onset was selected to predict the protection probability. Results: Neutralizing antibodies produced in symptomatic and unvaccinated patients infected with prototype strain could provide protection against Omicron reinfection, and the probability of protection gradually decreased with time. Neutralizing antibody level on day 28 after symptom onset provided protection probability of 30.3% (95%CI: 20.0%-45.5%) against reinfection, 51.5% (95%CI: 33.4%-75.9%) against symptomatic reinfection, and 91.2% (95%CI: 77.1%-97.7%) against severe reinfection caused by Omicron BA.5. The protection probability against Omicron BA.1, BA.4 and BA.5 reinfections decreased significantly 261 days after symptom onset, showing 9.6%-12.9%, 18.4%-23.9% and 63.1%-70.3% against three clinical outcomes, respectively. At the same time point and against the same clinical outcome, the protection probability of BA.1 was the highest, followed by BA.4 and BA.5. Conclusions: Neutralizing antibodies induced in symptomatic and unvaccinated COVID-19 patients previously infected with the prototype strain have limited protection probability against Omicron BA.5 reinfections and symptomatic reinfections. The protection probability against Omicron BA.5 reinfections is 30.3% 28 days after symptom onset and decreases to about 10% after 261 days. However, the protection probability against severe reinfections is considerable, with over 90% 28 days after symptom onset and still exceeding 60% after 261 days.

Abstract
We present improved germanium-based constraints on sub-GeV dark matter via dark matter-electron (χ-e) scattering using the 205.4 kg·day dataset from the CDEX-10 experiment. Using a novel calculation technique, we attain predicted χ-e scattering spectra observable in high-purity germanium detectors. In the heavy mediator scenario, our results achieve 3 orders of magnitude of improvement for m_{χ} larger than 80 MeV/c^{2} compared to previous germanium-based χ-e results. We also present the most stringent χ-e cross-section limit to date among experiments using solid-state detectors for m_{χ} larger than 90 MeV/c^{2} with heavy mediators and m_{χ} larger than 100 MeV/c^{2} with electric dipole coupling. The result proves the feasibility and demonstrates the vast potential of a new χ-e detection method with high-purity germanium detectors in ultralow radioactive background.

Abstract
A search for exotic dark matter (DM) in the sub-GeV mass range has been conducted using 205 kg day data taken from a p-type point contact germanium detector of the CDEX-10 experiment at China's Jinping underground laboratory. New low-mass dark matter searching channels, neutral current fermionic DM absorption (χ+A→ν+A) and DM-nucleus 3→2 scattering (χ+χ+A→ϕ+A), have been analyzed with an energy threshold of 160 eVee. No significant signal was found; thus new limits on the DM-nucleon interaction cross section are set for both models at the sub-GeV DM mass region. A cross section limit for the fermionic DM absorption is set to be 2.5×10^{-46} cm^{2} (90% C.L.) at DM mass of 10 MeV/c^{2}. For the DM-nucleus 3→2 scattering scenario, limits are extended to DM mass of 5 and 14 MeV/c^{2} for the massless dark photon and bound DM final state, respectively.

Abstract
Objective: To assess the therapeutic effect of the early interdisciplinary palliative care based on WARM model (whole, assessment, revaluation, management) on the quality of life, psychological state, pain and nutritional status in patients with non-small-cell lung cancer (NSCLC). Methods: A total of 60 patients from Chongqing University Cancer Hospital with newly diagnosed advanced NSCLC from Oct 15, 2019 to Jun 12, 2020 were enrolled. According to the method of random number table, the patients were divided into two groups: standard oncologic care group (SC, n=30) and early palliative care group (EPC, n=30). SC group only received standard oncological care, while EPC group received standard oncological care and additional comprehensive treatment from a MDT consisted of medical oncologists, palliative care nurses, dietitians and psychologists. The quality of life [functional assessment of cancer therapy-lung (FACT-L) scale], psychological state [hospital anxiety and depression scale (HADS) and patient health questionnaire-9 (PHQ-9)], nutritional status [patient-generated subjective global assessment (PG-SGA)], and cancer pain status [numerical rating scale (NRS)] were observed and compared between the two groups before and after the 6 months treatment, respectively. Results: A total of 45 patients completed 6 months treatment, including 24 males and 21 females, aged 38-82 (60.5±1.7), with 23 patients in the EPC group and 22 patients in the SC group. Patients assigned to EPC group had a better quality of life than those assigned to SC group [FACT-L scale: (122.3±1.6) vs (111.8±2.1), P<0.001]. Fewer patients had anxiety and depressive symptoms in the EPC group than those in the SC group [HADS anxiety subscale: (1.1±0.3) vs (2.9±0.4), P<0.001; HADS depression subscale: (0.7±0.3) vs (3.6±0.4), P<0.001]. The PHQ-9 results showed that 100.0% (23/23) patients were free of depression in the EPC group, while 45.5% (10/22) patients were free of depression in SC group (P<0.001). Furthermore, patients in the EPC group had a better nutritional status [moderate malnutrition: 60.9% (14/23); no malnutrition: 39.1% (9/23)] than those in the SC group [severe malnutrition: 40.9% (9/22); moderate malnutrition: 50.0% (11/22); no malnutrition: 9.1% (2/22)] (P<0.001). There was no significant difference in NRS score between EPC group and SC group (P=0.140). Conclusion: Early interdisciplinary palliative care based on WARM model can improve the quality of life, psychological state and nutritional status in NSCLC patients.

Abstract
Objective: To evaluate the cost-effectiveness of government fully-funded quadrivalent influenza vaccination (QIV) program for older adults aged 60 and above in mainland China. Methods: Based on decision tree model in the previous research on the cost-effectiveness analysis of TIV immunization, we extended the structure of model and updated the key parameters such as influenza patients' healthcare seeking behavior, vaccine cost, vaccine coverage and vaccine efficacy/effectiveness to estimate influenza-associated outpatient consultations, hospitalizations, respiratory disease excess mortality and quality-adjusted life years (QALY) between the QIV and no vaccination or TIV program. And incremental cost and incremental cost-effectiveness ratio (ICER) were evaluated between the QIV and no vaccination or TIV program from the societal perspective. The time frame of the study is one year. All costs were adjusted to 2019 using the consumer price index. Results: Comparing the fully-funded QIV and no vaccination or TIV for older adults aged 60 and above is separately expected to prevent 45 070 or 2 718 influenza-associated influenza-like illness (ILI) outpatients, 21 451 or 1 294 influenza-associated severe acute respiratory infection (SARI) hospitalizations, 19 346 or 1 167 influenza-associated respiratory excess deaths and avoid 155 234 or 9 363 QALY loss each year. Compared with no vaccination, introducing QIV into National Immunization Program (NIP) is expected to increase the cost of 11.71 billion yuan from the societal perspective. The incremental cost per QALY gained between QIV and no vaccination was 75 325 yuan per QALY, which is higher than willingness-to-pay (WTP) threshold (one-fold gross domestic product per capita is considered as WTP: 70 892 yuan) and means no cost effective. Introducing QIV rather than TIV into NIP will cost 7.98 billion yuan from the societal perspective and the ICER was 852.54 thousand yuan per QALY which is much higher than WTP and means no cost effective as well. The threshold of vaccination cost between QIV and no vaccination or TIV should no more than 113.41 or 6.83 yuan when the two comparators' scenarios above are all cost effective. Conclusion: Under the condition of current vaccine effectiveness and vaccine cost, comparing fully-funded QIV with no or TIV vaccination program is not cost effective for people aged 60 years or older.

Abstract
To improve the bioactivity of titanium alloy (Ti-6Al-4V), CaO-SiO2 coatings on titanium alloys were fabricated using laser cladding method. The effect of Na2O and ZnO on the microstructure and properties of the prepared coatings was discussed. The microstructure of the CaO-SiO2 coatings consists of cellular grains and cellular dendrites. The mutual diffusion of elements occurs between the coating and substrate. The base CaO-SiO2 coating is composed of different phases including CaTiO3, α-Ca2(SiO4), SiO2, TiO2 and CaO. The formation of CaTiO3 in the ceramic layer was analyzed through thermodynamics. Na2O has little influence on the microstructure, average hardness and wear resistance. When ZnO is added to the precursor, the microstructure turns to cell dendrite, and ZnO and Zn2SiO4 appear in the corresponding coating. The addition of ZnO reduces the average hardness and wear resistance of the ceramic layer. The in vitro soaking in SBF shows that the laser cladding coating has the ability to form an apatite layer.

Abstract
Objective: To evaluate consistency between 2-fold serial and 4-fold serial diluted neutralization tests against Enterovirus A71 (EV-A71) in estimating titer, Geometric mean titer (GMT), seroprevalence, and seroincidence. Methods: Based on a prospective cohort of 1-9 years old children, mothers and infants established in Anhua County, Hunan Province, during 2013-2018, from which 92 participants with a total of 386 blood specimens were sampled and tested with a 2-fold serial dilution and a 4-fold serial dilution neutralization tests against EV-A71 at the same time. Agreement was estimated using the Bland-Altman method. Stratified analysis was conducted to estimate effect dilution approach on GMT, seroprevalence and seroincidence. Results: The mean difference (0.04, 95%CI:-0.02-0.10) between the two dilution approaches was not significant. However, the limits of agreement (LOA) (-1.12-1.21), with the 95% confidence interval of upper LOA (1.10-1.31) and of lower LOA (-1.22--1.02), significantly exceeded the Clinic accept interval (-1, 1) indicating insufficient agreement between the two approaches in practice. While the dilution approaches did not affect estimates of GMT of the total population and the positive population, and seroincidence with seroconversion only, the differences were 2, 6 and 2%, respectively (P>0.05). Estimates of seroincidence with at least 4-fold increase and seroconversion/4-fold increase were significantly higher using a 4-fold dilution neutralization test compared to the 2-fold dilution neutralization test with 8% (95%CI: 1%-12%) and 9% (95%CI: 1%-17%), respectively. Conclusion: The 2-dilution and 4-dilution neutralization tests yielded comparable results when estimating the population's GMT; however, the difference between the two is not negligible when assessing the seroincidence.

Abstract
Objective: To evaluate the efficacy and long-term outcome of the bilaminar cortical wall building grafting technique for reconstruction of vertical and horizontal alveolar ridge defects in the esthetic zone. Methods: The retrospective study was conducted between January, 2007 and December, 2015. The sample was composed of 24 patients who received bilaminar cortical wall building augmentation in the esthetic zone in Department of Fourth Clinical Division, Peking University School of Stomatology. The 24 patients (11 female and 13 male) had age of (37.8±13.4) years (20-54 years). A bone block harvested from the lateral aspect of the mandibular ramus was bisected into two cortical laminae, which were then used to reconstruct the buccal and palatal walls of an alveolar ridge defect. The inter-laminar space was filled with particulate autogenous bone and the whole graft was covered with anorganic bone graft and collagen membrane. Bone width and vertical measurements were measured at the time of surgery and reentry surgery. Integration of the graft, implant survival rates and complications were recorded. Results: Overall, 24 patients with 35 sites who were included were followed for (7.1±1.9) years. Graft integration (24/24) and implant survival rates (35/35) were determined as 100%. The average horizontal and vertical bone gain was (6.47±2.46) and (5.01±1.12) mm with resorption rates of 9.0% and 10.9%, respectively. One patient showed soft-tissue dehiscence with peri-implant mucositis were observed 9 years after surgery. More than 1.5 mm of buccal bone plate were observed using cone beam computed tomography. Conclusions: This technique was effective and reliable for three-dimensional reconstruction of severely atrophic alveolar ridges in anterior maxillae. Autogenous graft combined with coverage by allogeneic bone graft and collagen membrane provided successful augmentation with low bone resorption.

Abstract
In the implant restoration of aesthetic area, the contour design of restoration has an important influence on the esthetic effect. The shape of subgingival portion of prosthesis, that is, the emergence profile plays an important role in aesthetic effect and health of the soft tissue. There are few studies on the contour design, indications, influencing factors of the emergence profile of the implant prosthesis. Most of the theoretical support for the contour design of implant restorations comes from the natural teeth restoration, but the design of implant and natural teeth restorations is not the same. This paper mainly reviews the design of emergence profile for implant restorations in the esthetic area, and provides and provides reference for clinical doctors.

Abstract
We report constraints on the dark photon effective kinetic mixing parameter (κ) with data taken from two p-type point-contact germanium detectors of the CDEX-10 experiment at the China Jinping Underground Laboratory. The 90% confidence level upper limits on κ of solar dark photon from 205.4 kg-day exposure are derived, probing new parameter space with masses (m_{V}) from 10 to 300 eV/c^{2} in direct detection experiments. Considering dark photon as the cosmological dark matter, limits at 90% confidence level with m_{V} from 0.1 to 4.0 keV/c^{2} are set from 449.6 kg-day data, with a minimum of κ=1.3×10^{-15} at m_{V}=200 eV/c^{2}.

Abstract
We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time of 3.2 yr within a 4.2-yr span are analyzed with analysis threshold of 250 eVee. Limits on WIMP-nucleus (χ-N) spin-independent cross sections as function of WIMP mass (m_{χ}) at 90% confidence level (C.L.) are derived using the dark matter halo model. Within the context of the standard halo model, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% C.L., respectively. These results correspond to the best sensitivity at m_{χ}<6 GeV/c^{2} among WIMP AM measurements to date.

Abstract
We report results on the searches of weakly interacting massive particles (WIMPs) with sub-GeV masses (m_{χ}) via WIMP-nucleus spin-independent scattering with Migdal effect incorporated. Analysis on time-integrated (TI) and annual modulation (AM) effects on CDEX-1B data are performed, with 737.1 kg day exposure and 160 eVee threshold for TI analysis, and 1107.5 kg day exposure and 250 eVee threshold for AM analysis. The sensitive windows in m_{χ} are expanded by an order of magnitude to lower DM masses with Migdal effect incorporated. New limits on σ_{χN}^{SI} at 90% confidence level are derived as 2×10^{-32}∼7×10^{-35} cm^{2} for TI analysis at m_{χ}∼50-180 MeV/c^{2}, and 3×10^{-32}∼9×10^{-38} cm^{2} for AM analysis at m_{χ}∼75 MeV/c^{2}-3.0 GeV/c^{2}.

Abstract
Objective: To evaluate the cost-effectiveness of potential government fully-funded influenza vaccination for diabetics in our country. Methods: From the societal perspective, a decision tree model was developed to compare outcomes (including impact on the influenza-related outpatient consultation, hospitalization and excess mortality, and quality-adjusted life years (QALY), as well as incremental cost-effectiveness ratio (ICER)) of a national fully-funded vaccination programme in the population with diabetes and status quo (i.e., vaccinated with out-of-pocket payment, with a uptake rate of zero), using the published data with regarding to influenza related ILI (influenza-like illness) consultation rate, hospitalization rate and excess mortality rate, health-related quality of life and economic burden, diabetes prevalence, population size, health seeking behaviour, vaccine uptake rate, vaccine efficacy/effectiveness, etc. A time horizon of 1 year was used in the present analysis, and all costs were expressed in CNY in 2016 using the consumer price index. All results are presented in M (P(25), P(75)). Results: In the scenario of 40% vaccination coverage in the population with diabetes, government fully-funded vaccination programme was estimated to cost 1.71 (1.67, 1.75) billions CNY, and expected to prevent 110 000 (81 000, 143 000) influenza-related ILI consultations, 36 000 (28 000, 44 000) influenza-related SARI hospitalizations and 12 000 (9 000, 16 000) influenza-related deaths due to respiratory and cardiovascular diseases. A total of 108 000 (82 000, 142 000) QALY were estimated to be gained. The ICER was 10 088 (7 365, 14 046) CNY per QALY gained. The probability of cost-effectiveness of the fully-funded vaccination programme was 99.1% at a threshold of 53 680 CNY per QALY gained (GDP per capita in 2016). Conclusion: Government fully-funded influenza vaccination in population with diabetes is cost-effective, and thus is recommended as the key strategy of diabetes prevention and control.

Abstract
Objective: To study the clinical characteristics of outpatients with hand, foot and mouth disease (HFMD) caused by different serotypes of enteroviruses. Methods: This was a prospective study. From February 2017 to March 2018, 563 outpatients with HFMD were enrolled by systematic sampling in the Department of Infectious Diseases, Henan Children's Hospital. Throat swabs were collected to determine the serotypes via PCR. Demographic, clinical, and laboratory data were collected by standard questionnaire. All cases were followed up twice at 2 and 9 weeks after the initial outpatient visit through telephone interview. A total of 563 cases were enrolled and 555 (98.6%) cases were positive for human enteroviruses, including 338 (60.9%) males. Analyses were stratified by enterovirus serotypes, Chi square test or Fisher's exact test, Rank sum test was used for comparison among different groups. Results: The age of 555 cases was 24.2 (16.4, 41.3) months. Among them 44.0% (224 cases) were identified as coxsackievirus (CV)-A6, while 189 cases, 35 cases, 14 cases and 73 cases were identified as CV-A16, enterovirus (EV)-A71, CV-A10 and other serotypes, respectively. Fever (≥37.5 ℃) was present in 51.4% (285/555) of laboratory confirmed cases. The proportions of fever in cases of CV-A6 (68.9%(168/244)) and CV-A10 (12/14) were significantly higher than those in cases of CV-A16 (31.7%(60/189),χ(2)=57.344,14.313,both P=0.000), other serotypes (43.8%(32/73),χ(2)=15.101 and 8.242, P=0.000 and 0.004) and EV-A71 (37.1%(13/35), χ(2)=13.506 and 9.441, P=0.000 and 0.002) respectively. There was no significant difference between CV-A6 and CV-A10 in presentation of fever (χ(2)=1.785, P=0.182). There were 359 cases (64.7%) with eruptions in mouth, hands, feet and buttocks. Cases infected with EV-A71 had the highest proportions (74.3%(26/35)) of rash emerging simultaneously in mouth, hands, feet, and buttocks. The proportion in cases of CV-A16, CV-A6, CVA10 and other serotype were 73.5% (139/189), 61.9% (151/244), 7/14 and 49.3% (36/73), respectively. The proportion of rash on other parts of body, such as face, limbs or torso in cases infected with CV-A6 (16.8% (41/244)) was the higherest and the proportion in cases of CV-A16, EV-A71, CV-A10 or other serotypes were 8.5% (16/189) , 5.7% (2/35) , 1/14, 6.8% (5/73) , respectively. None of these cases developed serious complications. Desquamation occurred in 45.5% (179/393) cases 7.5 (5.0, 9.0) days after disease onset and 13.5% (53/393) cases showed onychomadesis 31.0 (18.0, 33.5) days after disease onset. The proportion of desquamation and onychomadesis associated with CV-A6 (64.2% (95/148) and 31.8% (47/148)) was significantly higher than CV-A16 (31.8% (49/154) and 1.3% (2/154), χ(2)=33.601 and 52.482, both P=0.000) and other serotypes (38.0%(19/50) and 6.0%(3/50),χ(2)=10.236 and 12.988, P=0.001 and 0.000). Desquamation appeared more in cases of CV-A6 than in cases of CV-A10 (2/11,χ(2)=9.386, P=0.002), with the proportion of onychomadesis higher in CV-A6 than in EV-A71 (3.3% (1/30),χ(2)=11.088, P=0.001). Conclusion: Clinical manifestation such as fever, rash emerging parts, desquamation and onychomadesis are different among outpatient HFMD cases infected with CV-A16, CV-A6, EV-A71, CV-A10 and other enteroviruses.

Abstract
Objective: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Methods: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Results: The majority of radiation workers are engaged in diagnostic radiology, male is more than female. The abnormal rate of micronuclear (0.59‰) and chromosome aberration (0.47%) was highest in nuclear medicine workers. The abnormal rate of micronuclear and chromosome aberration was similar with interventional and diagnostic radiology. Expect for micronuclear (χ(2)=32.945, P<0.01) and chromosome aberration (χ(2)=75149.737, P<0.01) , other radiation sensitive indicators have no difference. The abnormal rate of thyroid function (18.8%) (χ(2)=12.084, P<0.01) , micronuclear (0.25‰) (χ(2)=57.359, P<0.01) , chromosome aberration (0.08%) (χ(2)=17.209, P<0.01) in group whose service length exceeding 20 years was higher than other service length groups. There is no statistical difference in other radiation sensitive indicators among different service length group. Conclusion: Long-term low doses of ionizing radiation could affect radiation worker's health, expecially radiation workers engaged in nuclear medicine and radiotherapy. We must pay attention to occupaitonal health care and management to ensure radiation worker's health.

Abstract
Objective: To understand characteristics of demographic, seasonal and spatial distribution of H5N1 cases in major countries of Asia (Indonesia, Cambodia, Vietnam, China) and Africa (Egypt). Methods: Through searching public data resource and published papers, we collected cases information in five countries from May 1st, 1997 to November 6th, 2017, including general characteristics, diagnosis, onset and exposure history, etc. Different characteristics of survived and death cases in different countries were described and χ(2) test was used to compare the differences among death cases and odds ratio (OR) and 95%CI value was used to compare death risk in different countries. Results: A total of 856 cases were reported in five countries with Egypt had the most cases (44.3%). The highest number of cases were reported in 2015 (18.3%). 53% cases were reported from January to March, and 96.1% of cases had the history of poultry exposure. 64.2% (43 cases) cases in China had live poultry market exposure, but the sick/dead poultry exposure was the major exposure for cases in other four countries. 452 death cases were reported in five countries, and the fatality rate was 52.8%. With Egypt as the reference group, the highest death risk was seen in Indonesia (OR (95%CI): 11.52 (7.46-17.77)), followed by Cambodia (OR (95%CI): 4.27(2.37-7.69)) and China (OR (95%CI): 2.87 (1.73-4.74)). The age distribution of death cases among 5 countries was statistically significant, and the highest fatality rate was in 15-54 years group in Egypt (83.6%, 102 cases), while in Cambodia the highest fatality rate was in 0-14 years group (76.9%, 30 cases). The highest number of deaths were reported in 2006, and 48.3% were reported from January to March. There was difference in exposure routes among 5 countries (χ(2)=43.85, P=0.001), 63.2% (24 cases) of the death cases in China had live poultry market exposure. 92.9% (79 cases), 83.3% (40 cases) and 100.0% (38 cases) death cases in Indonesia, Vietnam and Camodia had sick/dead poultry exposure, respectively;and 81.6% (31 cases) of the death cases in Egypt had backyard poultry exposure. Conclusion: The geographical distribution, seasonal age, gender, exposure matter and outcome of H5N1 cases in five countries were different.

Abstract
Objective: To estimate the serotype and age-specific hospitalization burden associated with hand, foot and mouth disease (HFMD) in Anhua county of Hunan province, between October 2013 and September 2016. Methods: We collected hospitalization records of HFMD patients from 6 virological surveillance hospitals, and reimbursement records through new rural cooperative medical system from 23 township health centers to estimate the age-specific hospitalization burden of HFMD in Anhua. Combined with the results of virological surveillance, the serotype-specific hospitalization burden of HFMD in Anhua, was estimated. Results: During the three years, it was estimated that 3 541 clinical diagnosed HFMD cases, including 3 146 laboratory-confirmed HFMD cases, were hospitalized in Anhua, but only one was diaguosed as being severe. The estimated average hospitalization rate was 723/100 000(95%CI: 699/100 000-747/100 000) for clinical diagnosed HFMD and 642/100 000 (95%CI: 620/100 000-665/100 000) for laboratory-confirmed HFMD between October 2013 and September 2016. The cases caused by Cox A16 (208/100 000) and Cox A6 (202/100 000) had higher hospitalization rates compared with the cases caused by EV71 (130/100 000), Cox A10 (38/100 000) and other enterovirus (64/100 000), and the difference was statistically significant (P<0.001). HFMD-associated hospitalization rates peaked in children aged 1 year (3 845/100 000), and then decreased with age. Compared with the hospitalized HFMD caused by EV71 and Cox A16, Cox A6-associated hospitalizations mainly occurred in younger age groups (P<0.001). Conclusion: Our study revealed a substantial hospitalization burden associated with mild HFMD caused by EV71, Cox A16, Cox A6 and Cox A10, especially in young children, in Anhua.

Abstract
Objective: To analyze the incidence and possible risk factors of 19 fractured implants out of 8 468 implants in 3 184 cases. Methods: During the 22-year clinical practice, clinical records of 18 patients with 19 fractured implants in 3 184 cases with 8 468 implants were analyzed to determine the following factors: location of the fractured implants, prosthodontics option, date of implant fracture, dimensions of fractured implants, complications prior to implant fracture and parafunctional habit. An evaluation of fractured implants was performed to identify possible factors that may predispose an implant to a higher risk of fracture. Results: Overall, the average duration of service of the implants was (7.0±4.5) years. Implant fracture occurred in 7 Camlog implants, 7 Nobel replace implants, 3 Ankylos implants and 2 Brånemark implants. No Thommen implant fractures were recorded. Amongst the 19 fractured implants, 8 occurred at the thinnest wall portion of the implant neck, 8 at the end of screw and 3 at the self-tapping thread region. All fractures were observed after functional loading. Furthermore, 9/19 (47.4%) of fractures occurred in the maxilla, indicating similar incidence rates in both arches (P=0.065). Most of fractures (16/19) occurred in the molar region and 18/19 in single implant-supported restorations. Totally 17 cases had received metal occlusal restorations. In 6 cases (35.5%), previous bone destruction apically extending to the level of implant fracture was documented before any clinical signs of fracture. Three fractured implants were removed and simultaneously re-implanted with larger-diameter implants, while the rest of the cases were left to heal, followed by a second-stage surgery. Conclusions: Within the limitation of this analysis, the study demonstrated that appropriate implant-abutment connection design, implant diameter, prosthetic strategy and bone resorption are crucial to the long-term performance of implants. There is no significant difference of fractures rates in both archs.

Abstract
Objective: To evaluate the preliminary clinical outcome of socket shield technique in maxillary anterior region. Methods: Nine patients were treated with socket shield technique in Peking University School and Hospital of Stomatology from February 2012 to December 2015 were enrolled in this study. Ten implants were placed and restored immediately. After 12-48 months' follow-up (averaged 32 months), the peri-implant hard and soft tissue were clinically evaluated. Results: No implants were lost during the observation period, resulting a cumulate 32-month survival. The pink esthetic score (PES) was 13.5. Mesial and distal bone loss were 0.17 mm and 0.22 mm respectively. Conclusions: To achieve good esthetic results, socket shield technique may be an option for maxillary anterior region immediate implant placement.

Abstract
We report the first results of a light weakly interacting massive particles (WIMPs) search from the CDEX-10 experiment with a 10 kg germanium detector array immersed in liquid nitrogen at the China Jinping Underground Laboratory with a physics data size of 102.8 kg day. At an analysis threshold of 160 eVee, improved limits of 8×10^{-42} and 3×10^{-36} cm^{2} at a 90% confidence level on spin-independent and spin-dependent WIMP-nucleon cross sections, respectively, at a WIMP mass (m_{χ}) of 5 GeV/c^{2} are achieved. The lower reach of m_{χ} is extended to 2 GeV/c^{2}.

Abstract
OBJECTIVES Findings regarding the benefits of fruit and vegetables (FV) on weight control are inconsistent and little is known among Chinese populations. Therefore, we examined the relationship between change in FV consumption, weight, and change in body mass index (BMI) among Chinese adults, participants of the China Health and Nutrition Survey (CHNS). STUDY DESIGN A prospective cohort study. METHODS Two waves of CHNS conducted in 2006 and 2011 were used. Continuous FV consumption increase was considered as the exposure and changes in weight and BMI as outcomes. Change in FV consumption was categorized into quintiles. Analysis of covariance and multiple linear regression models, after controlling for potential confounders such as energy intake, physical activity, and smoking, were used to describe the relationship between change in FV consumption and change in weight and BMI. RESULTS A total of 4357 participants aged 18-65 years were included in this study. The respective weight and BMI gains in male individuals were 1.81 kg and 0.73 kg/m2 in the fifth quintile of FV change relative to individuals in the first quintile (3.67 kg for weight gain and 1.48 kg/m2 for BMI gain). An increase in FV consumption by 100 g was associated with a 211 g weight loss (B = -2.11; 95% confidence interval [CI], -3.34, -0.89, P < 0.001) and a decrease in BMI by 0.94 kg/m2 (B = -0.94; 95% CI, -1.36, -0.46, P < 0.001) in men; and a 140 g weight loss (B = -0.14; 95% CI, -0.97, 0.69, P = 0.74) and a decrease in BMI by 0.29 kg/m2 BMI (B = -0.29; 95% CI, -0.63, 0.06, P = 0.11) in women. CONCLUSIONS Increase in FV consumption was associated with statistically significant weight loss and decrease in BMI among Chinese men, and, although suggested, weight loss among women was not significant. Considering the protective effect of FV on human health, increasing FV consumption in the Chinese population is recommended.

Abstract
OBJECTIVES To explore the association between obesity phenotype and the risk of hypertension among Chinese adults. STUDY DESIGN A prospective cohort study. METHODS Two waves of data were collected in 2009 and 2011 by the China Health Nutrition Survey. According to International Diabetes Federation and Chinese obesity criteria, participants were divided into four groups: metabolically healthy non-overweight/obesity (MHNO), metabolically healthy overweight/obesity (MHO), metabolically abnormal non-overweight/obesity (MANO), and metabolically abnormal overweight/obesity (MAO). Logistic regression model was performed to estimate the risk of hypertension with obesity phenotype. RESULTS Among a total of 4604 adults aged 18-65 years at baseline, 467 developed hypertension during the 2-year follow-up period. After adjusting for several potential confounders, significantly increased risks for hypertension were found for participants in MHO (odd ratio [OR]: 1.78, 95% confidence interval [CI]: 1.39-2.27), MANO (OR: 1.71, 95% CI: 1.02-2.86), and MAO (OR: 3.35, 95% CI: 2.54-4.42) group compared with the MHNO group. CONCLUSION Metabolically abnormal individuals, regardless of their body weight status, showed significantly higher risks for hypertension compared with healthy non-overweight/obese group. Furthermore, MHO individuals had significantly increased risk of incident hypertension.

Abstract
The aim of this study was to analyze and compare the long-term clinical outcomes of mature third molar autotransplantation in surgically created sockets and fresh extraction sockets with regard to survival and functional success rates. A total of 65 third molars with completely formed roots were autotransplanted in 60 patients (average age 33.1 years). Thirty-six of the teeth were autotransplanted into surgically created sockets with or without guided bone regeneration (GBR; delayed autotransplantation), while 29 were autotransplanted into fresh extraction sockets (immediate autotransplantation; control group). All patients underwent annual clinical and radiographic examinations (average follow-up 9.9 years, range 7-13 years). The survival rates for the control, GBR, and no GBR groups were 93.1%, 95.2%, and 80.0%, respectively, with no significant differences among the groups. There were no statistically significant differences among the groups with regard to the frequency of inflammatory root resorption or root ankylosis. Age did not influence the clinical outcomes. These results suggest that the autotransplantation of third molars with completely formed roots is effective in both surgically created and fresh extraction sockets and provides a high long-term success rate if cases are selected and treated appropriately.

Abstract
This paper presents preliminary data on the genetic diversity and population structure of Hyporhamphus sajori by analysing a 510 bp sequence in the mitochondrial DNA (mtDNA) control region and eight polymorphic microsatellite DNA loci. The H. sajori individuals from different locations were indistinguishable from one another based on mtDNA variation, as demonstrated with a neighbour-joining tree and minimum spanning network analysis. Low level of genetic diversity and the absence of population structure in H. sajori from the north-west Pacific Ocean, combined with negative indices for neutral evolution in these populations, suggest that H. sajori underwent a population expansion after a recent bottleneck. The Structure analysis, discriminant analysis of principal components (DAPC) and the pair-wise ΦST values after Bonferroni correction using eight microsatellite loci provided no clear inference on the genetic differentiation and thus no evidence of population structure of H. sajori. The genetic connectivity among locations might be due to fairly high gene flow via transport of eggs and larvae by the Kuroshio and Tsushima warm current. This study revealed low levels of genetic diversity and suggested high level of contemporary gene flow among populations of H. sajori in the East (Japan) Sea and the Pacific Ocean.

Abstract
OBJECTIVE To investigate chromosome aberration and micronucleus frequency in peripheral blood lymphocytes in workers engaged in radiation for a long time, to reduce occupational hazard caused by ionizing radiation, and to further strengthen health surveillance. METHODS A total of 366 members of medical staff engaged in radiation work who underwent physical examinations in Hangzhou Hospital of Prevention and Treatment of Occupation Diseases from 2014 to 2015 were enrolled as radiation group, consisting of staff engaged in X-ray diagnosis, diagnostic radiology, radiotherapy, and interventional radiology. Another 100 members of medical staff without exposure to radiation were enrolled as control group. Whole blood culture was used to measure chromosome aberration and micronucleus frequency in peripheral blood lymphocytes. RESULTS The radiation group had a significantly higher rate of chromosome aberration than the control group (0.30% vs 0.09% , χ(2)= 13.43, P<0.01), as well as a significantly higher micronucleus frequency than the control group (2.09‰ vs 0.08‰, χ(2)=74.4, P<0.01). The abnormal rates of chromosome aberration and micronucleus showed no significant differences across radiation workers with different working years (P>0.05). The staff engaged in X-ray diagnosis, diagnostic radiology, radiotherapy, and interventional radiology had rates of chromosome aberration of 0.25%, 0.25%, 0.23%, and 0.41%, respectively, which showed a significant difference between the staff at these four posts (χ(2)=8.22, P<0.05); the micronucleus frequencies in the staff at these four posts were 1.36‰, 1.28‰, 1.14‰, and 3.79‰, respectively, and showed a significant difference between the staff at these four posts (χ(2)=251.09, P<0.01). CONCLUSION Radiation workers are exposed to lowdose ionizing radiation for a long time, which may cause significant increases in the rate of chromosome aberration and micronucleus frequency in peripheral blood lymphocytes.

Abstract
In the silkworm (Bombyx mori), tolerance to fluoride and scaleless wings are controlled by the dominant gene Dtf (dominant tolerance to fluoride) and recessive gene nlw (no Lepidoptera wings), respectively, and these genes have been mapped by using simple sequence repeat and sequence tag site markers. Marker-assisted evaluation and selection of silkworms with fluoride tolerance and scaleless wings were used for predicting fluoride resistance and scaleless wings in backcrossed animals. A silkworm strain was bred using this method, and its economic characteristics were found to be similar to those of commercial silkworms. These methods will therefore be useful for silkworm breeding programs and in screening for two or more characteristics of interest for segregating populations.

Abstract
The present study investigates the effects of electroacupuncture (EA) on urinary bladder pressure (UBP) in patients with acute gastrointestinal injury (AGI). Twenty patients with AGI admitted to the First Hospital of Jiaxing intensive care unit from December 2011 to June 2013 were evaluated. Conventional group patients (n = 10) were administered moderate enteral nutritional support, and electroacupuncture group patients (n = 10) were administered enteral nutritional support followed by EA at bilateral Zusanli (ST-36), Shangjuxu (ST-37), Hegu (LI-4), and QuChi (LI-11) acupoints. UBP was then measured every 6 h and the serum creatinine once daily for 7 days. There were no statistically significant patient demographic differences in the study groups (P > 0.05). The initial UBP of both patient groups was ≥12 mmHg. On days 6 and 7, the UBP significantly decreased in the EA group compared to the conventional group (P < 0.05). The serum creatinine concentration on day 7 was significantly lower in the EA group than in the conventional group (P < 0.05). Based on these results, electroacupuncture contributed to gastrointestinal motility recovery in patients with AGI. This procedure may reduce UBP and provide organ-protective effects in AGI patients.

Abstract
WHAT IS KNOWN AND OBJECTIVE The current pharmacotherapeutic treatment of major depressive disorder (MDD) generally takes weeks to be effective. As the molecular action of these drugs is immediate, the mechanistic basis for this lag is unclear. A drug that has a more rapid onset of action would be a major therapeutic advance and also be a useful comparator to provide valuable mechanistic insight into the disorder and its treatment. COMMENT Recent evidence suggests that ketamine produces rapid-onset antidepressant action. Important questions are as follows: is it specific or coincidental to other effects; is there a dose-response relationship; and is the mechanism related to that of current antidepressants. NMDA receptor antagonism is unlikely the explanation for ketamine's antidepressant action. WHAT IS NEW AND CONCLUSION It is not an exaggeration to state that the new findings, if validated, might produce a revolution in understanding and treating depressive disorders.

Abstract
Melanoma has traditionally been viewed as a radioresistant cancer. However, recent studies suggest that under certain clinical circumstances, radiotherapy may play a significant role in the treatment of melanoma. Previous studies have demonstrated that telomere length is a hallmark of radiosensitivity. The newly discovered mammalian CTC1-STN1-TEN1 (CST) complex has been demonstrated to be an important telomere maintenance factor. In this study, by establishing a radiosensitive/radioresistant human melanoma cell model, MDA-MB-435/MDA-MB-435R, we aimed to investigate the association of CTC1 expression with radiosensitivity in human melanoma cell lines, and to elucidate the possible underlying mechanisms. We found that CTC1 mRNA and protein levels were markedly increased in the MDA-MB-435R cells compared with the MDA-MB-435 cells. Moreover, the downregulation of CTC1 enhanced radiosensitivity, induced DNA damage and promoted telomere shortening and apoptosis in both cell lines. Taken together, our findings suggest that CTC1 increases the radioresistance of human melanoma cells by inhibiting telomere shortening and apoptosis. Thus, CTC1 may be an attractive target gene for the treatment of human melanoma.

Abstract
Lipomembranous changes are distinctive histopathological findings, which include the presence of cystic cavities lined by crenulated, hyaline membranes in adipose tissue. It is likely that ischaemia is fundamental to the development of these lesions, and that lipomembranes are formed from the products of degenerating fat cell membranes by some unknown mechanism. Such changes may be seen, although rarely, in many types of subcutaneous inflammatory processes. However, an association with systemic lupus erythematosus (SLE) is rare. We report a patient with SLE who had the histological features of lipomembranous changes associated with vasculopathy.

Abstract
This study investigated the association between the total choline (tCho) concentration and the clinical characteristics and biomarker status of breast cancer. Sixty-two patients with breast cancer, 1.5 cm or larger in size on MR images, were studied. The tCho concentration was correlated with the MRI features, contrast enhancement kinetics, clinical variables and biomarkers. Pairwise two-tailed Spearman's nonparametric test was used for statistical analysis. The tCho concentration was higher in high-grade than moderate-/low-grade tumors (p = 0.04) and in tumors with higher K(trans) and k(ep) (p < 0.001 for both). The association of tCho concentration with age (p = 0.05) and triple negative biomarker (p = 0.09) approached significance. tCho was not detected in 17 patients, including 15 with invasive ductal cancer and two with infiltrating lobular cancer. Fifteen of the 17 patients had moderate- to low-grade cancers, and 11 had human epidermal growth factor-2-negative cancer, suggesting that these two factors might lead to false-negative choline. Higher tCho concentration in high-grade tumors and tumors with higher K(trans) and k(ep) indicates that choline is associated with cell proliferation and tumor angiogenesis. The higher choline level in younger women may be caused by their more aggressive tumor type. The results presented here may aid in the better interpretation of (1)H MRS for the diagnosis of breast lesions.

Abstract
Abstract
PURPOSE: MRI is known as the most accurate imaging modality for evaluating the extent of residual disease following neoadjuvant chemotherapy (NAC). Although in general breast MRI is done at 1.5T, 3T can provide a better signal-to-noise ratio and may be more sensitive to detect residual disease. In this study the diagnostic performance of 3T MRI for NAC response was investigated.
METHODS AND MATERIALS: In a period of 30 months, 42 NAC patients (29-83 y/o, mean 50 y/o) who received at least three MRI scans before, during and after therapy, and had surgery after completing NAC were analyzed in this study. The NAC protocol included albumin-bound paclitaxel, carboplatin and trastuzumab for HER-2 positive patients (N= 15), or bevacizumab for HER-2 negative patients (N=27). Some patients received doxorubicin and cyclophosphamide, bi-weekly for 4 cycles, as clinically indicated. Twenty-eight lesions were mass types and 14 showed non-mass-like enhancements. The residual tumor size was determined using the RECIST criteria, by measuring the longest dimension shown on MRI. When there was no enhancement (or, with a faint enhancement equal to the background normal tissue enhancement), the case was determined as complete clinical response (CCR). Pathological complete response (pCR) was defined as no residual invasive cancer cells, with or without DCIS. In cases with residual invasive cancer, the pathological size was determined as the longest dimension, either the longest dimension on H&E-stained slide or from the number of blocks (each 5 mm) where the malignant invasive tumor was detected, whichever was greater. For residual tumor showing as scattered cancer cells/nests, the longest dimension was estimated from the involved blocks.
RESULTS: MRI diagnosed 12 complete clinical response and 30 cases with residual cancers. In pathological examination, 12 were pCR (29%). Overall, comparing MRI diagnosis to pCR diagnosis, there were 27 true positive, 9 true negative, 3 false negative, and 3 false positive. The three false positive cases all had residual DCIS-so although MRI did not predict pCR it correctly diagnosed residual DCIS. The three false negative cases were all non-mass lesions, in which pathology showed scattered small cancer foci in 3, 14, and 14 cm areas, respectively. The sensitivity, specificity, and accuracy of MRI were 90%, 75%, and 86%. Overall, the correlation between MRI and pathologic size was higher for mass lesions than for non-mass-like lesions (r=0.80 vs. r=0.67), and similar between Her-2 positive and negative lesions (r=0.82 vs. r=0.84). The discrepancy between MRI and pathological size was larger for non-mass lesions than for mass lesions (0.6-14 cm vs. 0-3 cm).
CONCLUSIONS: Similar to 1.5T, high resolution 3T MRI has limitations for the non-mass-like lesions that break into small foci and scattered cells. This might be due to that small tumor foci have lowered angiogenic activity, limiting MR contrast agent uptake, thus lowering the detection rate. For mass lesions, MR residual tumor size was highly correlated with pathological size. Understanding the accuracy and limitations of 3T MRI for NAC patients may aid in designing an improved NAC protocol and a better surgical planning.

Abstract
Vocalizations of male and female African clawed frogs (Xenopus laevis) are generated by brain stem central pattern generators. Serotonin (5-HT) is likely important for vocal initiation because, when applied in vitro, sex-typical fictive vocalizations are evoked from isolated brains. To explore the mechanisms underlying vocal initiation, we identified the types of serotonin receptors mediating vocal activation pharmacologically using a whole brain, fictive preparation. The results showed that 5-HT(2C)-like receptors are important for activation of fictive vocalizations in the sexes. 5-HT(2C) receptor agonists elicited fictive vocalizations, and 5-HT(2C) receptor antagonists blocked 5-HT-induced fictive vocalizations, whereas agonists and antagonists of 5-HT(2A) and 5-HT(2B) receptors failed to initiate or block 5-HT-induced fictive vocalizations in the sexes. The results indicate that serotonin initiates fictive vocalizations by binding to 5-HT(2C)-like receptors located either within or upstream of the vocal central pattern generator in both sexes. We conclude that the basic mechanism of vocal initiation is shared by the sexes despite the differences in the actual vocalizations between males and females. Sex-typical vocalizations, therefore, most likely arise from activation of different populations of 5-HT(2C) receptor expressing cells or from differential activation of downstream pattern generating neurons.

Abstract
We report a diabetic renal transplant recipient who presented with fever and right lower quadrant abdominal pain. Acute appendicitis was considered initially and she underwent emergent appendectomy. However, persistent symptoms postoperatively made us perform an imaging study to identify the problems. Abdominal and pelvic computed tomography disclosed several focal wedge-shaped lesions of low attenuation in the renal allograft. Acute lobar nephronia was successfully managed with parenteral antibiotics. The patient recovered without any sequela. A renal allograft in the right iliac fossa complicates the diagnosis among acute renal infection, malignancy, acute rejection, and even acute appendicitis. Biopsy of the renal allograft is sometimes needed due to clinically ambiguous imaging results. In this report, we not only detail the clinical course of such a rare case, but also review the previous 3 cases of acute lobar nephronia in renal allografts in the literature.

Abstract
Bronchogenic cyst is noted shortly after birth or in early childhood and usually presents as a swelling or draining sinus in the presternal area. Its origin and pathogenesis can be explained as a developmental anomaly of the tracheobronchial buds from the primitive foregut. The patient was a 4-year-old boy with a child-fist-sized soft mass over his left scapula, which had been detected at birth and had been gradually growing. Grossly, it appeared to be a simple cyst with clear mucoid fluid. Histopathological study demonstrated a unilocular cyst composed of ciliated pseudostratified columnar epithelia, interspersed goblet cells, smooth muscles, and mucous glands on the cyst wall, which are features compatible with cutaneous bronchogenic cyst.

Abstract
BACKGROUND/AIMS Although the therapeutic results of gastric cancer have markedly improved, it still remains the most common cancer death in Korea. METHODOLOGY The clinicopathologic characteristics were analyzed for 11,491 consecutive patients who underwent operation for gastric cancer at the Department of Surgery, Seoul National University Hospital from 1971 to 1997. We also evaluated the survival and prognostic factors for 9,262 consecutive patients from 1981 to 1996. The prognostic significance of treatment modality [surgery alone, surgery + chemotherapy, surgery + immunotherapy + chemotherapy (immunochemo-surgery)] were evaluated in stage III gastric cancer. RESULTS The 5-year survival rate of overall patients was 55.8%, and that of patients who received curative resection was 64.8%. The 5-year survival rates according to TNM stage were 92.9% for Ia, 84.2% for Ib, 69.3% for II, 45.8% for IIIa, 29.6% for IIIb and 9.2% for IV. Depending on the extent of resection, the 5-year survival rates were 68.7% for STG, 45.4% for TG, 19.6% for combined resection and there was no 5-year survivor in the nonresection group. Regarding adjuvant treatment modality, significant survival difference was observed in stage III patients. The 5-year survival rates were 44.8% for the immunochemo-surgery group, 36.8% for the surgery + chemotherapy group and 27.2% for the surgery alone group. CONCLUSIONS Curative resection, depth of invasion and lymph node metastasis were the most significant prognostic factors in gastric cancer. Consequently, early detection and curative resection with radical lymph node dissection, followed by immunochemotherapy especially in patients with stage III gastric cancer should be recommended as a standard treatment principle for patients with gastric cancer.

Acute generalized pustular psoriasis (GPP) is a rare, sometimes fatal, exudative form of psoriasis characterized by acute febrile pustular psoriasis. Unlike the adult forms, GPP in childhood tends to undergo a more benign course. It may resolve spontaneously with only supportive treatment, but may sometimes be life threatening and resistant to therapy. We report a case of GPP in 7-year-old girl treated successfully with dapsone.

Abstract
OBJECTIVES The aim of this study was to characterize the urodynamic findings in patients with cervical cancer before radical hysterectomy and to correlate the results with age, parity, menopausal status, and cancer stage. METHODS All patients with cervical cancer before radical hysterectomy who underwent urodynamic study (UDS) from January 1996 through December 1998 were enrolled. Detailed history, physical examination, and multichannel UDS data including uroflowmetry, filling and voiding cystometry, stress urethral pressure profile, and 20-min pad test were obtained for each patient. The urodynamic findings of each patient were analyzed and correlated with age, parity, menopausal status, and cancer stage. RESULTS A total of 210 patients with cervical cancer were included in the study. The mean age was 48.9 +/- 10.5 years with a mean parity of 3.3 +/- 1.7. Forty-two percent (n = 88) of patients were menopausal, and 88% (n = 184) belonged to stage IB while 10% (n = 20) were stage IIA and 2% (n = 6) stage IIB. Urodynamic study showed that only 17% (n = 37) of the 210 patients were normal, 10% (n = 21) had voiding dysfunction, 45% (n = 94) had storing dysfunction, and 28% (n = 58) had both voiding and storing dysfunctions. In addition, 51% (n = 106) had urinary incontinence and 37% (n = 78) had genuine stress incontinence (GSI), 8% (n = 16) detrusor instability (DI), and 6% (n = 12) GSI/DI. Age, parity, and cancer stage did not show any significant differences among these four groups. CONCLUSIONS In this series, only 17% of patients with cervical cancer had normal urodynamic findings before radical hysterectomy.

Abstract
1. It has been documented that ageing may alter endogenous neurotransmitters. However, these results are controversial. Thus, in the present study, cerebral cortex and plasma from male Wistar rats aged 8 weeks and 6, 12 or 24 months were used to investigate the changes in monoamines using electrochemical detection. 2. A marked decrease in L-dihydroxyphenylalanine (L-DOPA) was observed in aged rats. Like the decrease in dopamine (DA), levels of 5-hydroxytryptamine (5-HT) and 5-hydroxyindolacetic acid (5-HIAA), the major metabolite of 5-HT, in aged rats were decreased in the cerebral cortex and plasma. Plasma levels of noradrenaline and levels of adrenaline in the cerebral cortex were also decreased in aged rats. Moreover, levels of 3,4-dihydroxyphenylacetic acid (DOPAC), a metabolite of DA, in the cerebral cortex and plasma were reduced by ageing. The level of homovanillic acid (HVA) in all samples was markedly increased with ageing. 3. The ratio of DOPAC/DA and 5-HIAA/5-HT, being closely linked with the activity of monoamine oxidase, was increased in the cerebral cortex and plasma with ageing. The ratio of HVA/DOPAC, an index of the activity of catechol-O-methyltransferase, was also higher in the cerebral cortex and plasma of aged rats. 4. These data suggest that ageing may alter endogenous monoamines in both the brain and peripheral tissues.
