Abstract
Bisphenol A (BPA) is a common synthetic endocrine disruptor that can be utilized in the fabrication of materials such as polycarbonates and epoxy resins. Numerous studies have linked BPA to learning and memory problems, although the precise mechanism remains unknown. Gamma-aminobutyric acid (GABA) is the most abundant inhibitory neurotransmitter in the vertebrate central nervous system, and it is intimately related to learning and memory. This study aims to evaluate whether altered cognitive behavior involves the GABA signaling pathway in male offspring of rats exposed to BPA during the prenatal and early postnatal periods. Pregnant rats were orally given BPA (0, 0.04, 0.4, and 4 mg/kg body weight (BW)/day) from the first day of pregnancy to the 21st day of breastfeeding. Three-week-old male rat offspring were selected for an open-field experiment and a new object recognition experiment to evaluate the effect of BPA exposure on cognitive behavior. Furthermore, the role of GABA signaling markers in the cognition affected by BPA was investigated at the molecular level using western blotting and real-time polymerase chain reaction (RT-PCR). The research demonstrated that BPA exposure impacted the behavior and memory of male rat offspring and elevated the expression of glutamic acid decarboxylase 67 (GAD67), GABA type A receptors subunit (GABAARα1), and GABA vesicle transporter (VGAT) in the hippocampus while decreasing the expression levels of GABA transaminase (GABA-T) and GABA transporter 1 (GAT-1). These findings indicate that the alteration in the expression of GABA signaling molecules may be one of the molecular mechanisms by which perinatal exposure to BPA leads to decreased learning and memory in male rat offspring.

Abstract
OBJECTIVES This study aimed to analyze the role of estrogen in noise-induced hearing loss (NIHL) and uncover underlying mechanisms. METHODS An ovariectomized Sprague-Dawley rat model (OVX) was constructed to investigate the hearing threshold and auditory latency before and after noise exposure using the auditory brainstem response (ABR) test. The morphological changes were assessed using immunofluorescence, scanning electron microscopy and transmission electron microscopy. Proteomics and bioinformatics were used to analyze the mechanism. The findings were further verified through western blot and Luminex liquid suspension chip technology. RESULTS After noise exposure, OVX rats exhibited substantially elevated hearing thresholds. A conspicuous delay in ABR wave I latency was observed, alongside increased loss of outer hair cells, severe collapse of stereocilia and pronounced deformation of the epidermal plate. Accordingly, OVX rats with estrogen supplementation exhibited tolerance to NIHL. Additionally, a remarkable upregulation of the thrombospondin 1 (Tsp1)-CD47 axis in OVX rats was discovered and verified. CONCLUSIONS OVX rats were more susceptible to NIHL, and the protective effect of estrogen was achieved through regulation of the Tsp1-CD47 axis. This study presents a novel mechanism through which estrogen regulates NIHL and offers a potential intervention strategy for the clinical treatment of NIHL.

Abstract
PURPOSE The goal of this study is to compare traditional percutaneous nephrolithotomy (PCNL) and needle-perc-assisted endoscopic surgery (NAES) in the treatment of complicated solitary kidney stones via a single-center randomized controlled prospective study. METHODS A total of patients with complex (Guy's score II-IV) solitary kidney stones between July 2019 to June 2022 were enrolled in the study. Participants were stratified into two groups: needle-perc-assisted endoscopic surgery group (group A) and traditional PCNL group (group B). All procedures were finished by X-ray free technique. The clinical characteristics and outcomes were analyzed. RESULTS A total of 90 (44 in Group A and 46 in Group B) patients were finally included in our study. There were no statistically differences in terms of gender, age, body mass index (BMI), stone burden between two groups. The mean operative duration of Group A was significant higher than group B (95.1 ± 21.4 min vs 72.5 ± 29.5 min, p=0.02). The 1-month stone-free rate (SFR) was significant higher in Group A than B (90.9% vs 73.9%, p=0.03). A less hemoglobin drop (p=0.01), shorter postoperative in-hospital day (p=0.04), and lower severe complication (Clavien-Dindo III and above) rates (p=0.03) were observed in Group A. CONCLUSION For patients with solitary kidney stones, NAES technique provides a higher one-session SFR, a better renal function recovery and compared with traditional PCNL.

Abstract
INTRODUCTION The goal of this study was to evaluate the efficacy and safety of needle-perc-assisted endoscopic surgery (NAES) in the treatment of staghorn renal stones via a single-center prospective randomized controlled study. METHODS A total of 219 patients with partial or complete staghorn renal stones were prospectively randomized into two groups between January 2020 and April 2022. In group A (n = 112), patients were treated with traditional standard access, multiple if necessary, and in group B (n = 107), only one standard access was made, and needle-perc was assisted to remove the residual stones in the same stage. All procedures were guided under ultrasound totally. Stone size, operating time, blood loss, pain score, complications, and other related characteristics were monitored and analyzed. RESULTS Procedures were successful in all patients. The baseline characters were similar between the groups. The mean stone size was comparable (4.5 ± 1.4 vs. 4.7 ± 1.7, p = 0.35). The 1-month stone-free status was achieved in 85 patients (75.9%) in group A and 80 (74.8%) patients in group B (p = 0.72). The operation time was shorter in group A than B (75.1 ± 28.1 min vs. 97.2 ± 20.4 min, p = 0.02). A less blood loss (p = 0.01), shorter hospital stay (p = 0.04), lower pain score (p = 0.04), and lower severe complication rates (p = 0.03) were observed in group B. CONCLUSION NAES reveals better postoperative recurrence compared with traditional multiple tracts method for treating staghorn renal stones. The stone-free rate was comparable between the two groups.

Abstract
Carboxylesterases (CarEs) are a multifunctional superfamily of enzymes and play an important role in detoxification of various insecticides in insects. The oriental fruit fly, Bactrocera dorsalis, is one of the most destructive agricultural pests and has developed different degrees of resistance to organophosphates in field. However, the involvement of BdCarEs in tolerance or resistance to other alternative insecticides are still unclear. In the present study, 33 BdCarEs genes were identified based on the genome database of B. dorsalis. Phylogenetic analysis demonstrated that they were classified into nine clades, with abundance of α-esterases. Meanwhile, the sequence characterization and the chromosome distribution were also analyzed. The spatiotemporal expression analysis of BdCarEs genes suggested that the diversity of potential function in different physiological processes. With the exception of BdCarE21, all BdCarEs genes responded to at least one insecticide exposure, and BdCarE20 was found to be up-regulated after exposure to all five tested insecticides individually. Eight BdCarEs genes were overexpressed in MR strain when compared to that in SS strain. Subsequently, knockdown the expression of representative BdCarEs genes significantly increased the susceptibility of the oriental fruit fly to corresponding insecticides, which indicated that the tested BdCarEs genes contributed to one or multiple insecticide detoxification. These findings provide valuable insights into the potential role in respond to tolerance or resistance to insecticides with different mode of action, and will facilitate development of efficiency management strategy for B. dorsalis.

Abstract
INTRODUCTION The aim of the study was to assess the safety and efficacy of ultrasound (US)-guided percutaneous nephrolithotomy (PCNL) for complex renal stones when performed in a modified supine position. METHODS We retrospectively reviewed the charts of patients who underwent PCNL for complex renal stones at our institution between August 2018 and December 2021. During this time, 188 consecutive patients underwent US-guided PCNL in the prone position (P group, n = 129) or in the flank-free modified supine position (S group, n = 59). Patient demographics and intraoperative and postoperative data were analyzed. RESULTS Successful renal access was achieved in all patients. The baseline demographics were comparable between the two groups. The numbers of renal access were significantly higher (2.1 ± 0.4 vs. 1.2 ± 0.2, p = 0.002), and the operation time was comparable (79.1 ± 14.6 min vs. 96.2 ± 19.6 min, p = 0.06) between the two groups. The postoperative hospital stay was also shorter in the P group (6.2 ± 1.5 d vs. 10.2 ± 1.7 d, p = 0.008). The postoperative hemoglobin loss was similar between the P and S groups (1.7 ± 0.4 g/dL vs. 1.8 ± 0.3 g/dL, p = 0.12). The stone-free rate was significantly lower in the S group (57.5% vs. 82.7%, p < 0.001). There were no embolization or septic complications. Twelve patients (20.3%) in the S group underwent simultaneous or staged retrograde flexible ureteroscopy to remove residual stones. CONCLUSION US-guided PCNL in the modified supine position was a safe treatment for complex renal stones. However, the single-session stone clearance rate was not ideal. The supine flank-free position may be unsuitable for US-guided PCNL in patients with complex renal stones according to our preliminary findings.

Abstract
Background: Lung adenocarcinoma (LUAD), the most common histotype of lung cancer, may have variable prognosis due to molecular variations. This work investigated long non-coding RNA (lncRNA) related to endoplasmic reticulum stress (ERS) to predict the prognosis and immune landscape for LUAD patients. Methods: RNA data and clinical data from 497 LUAD patients were collected in the Cancer Genome Atlas database. Pearson correlation analysis, univariate Cox regression, least absolute shrinkage and selection operator regression analyses, as well as the Kaplan-Meier method, were used to screen for ERS-related lncRNAs associated with prognosis. The risk score model was developed using multivariate Cox analysis to separate patients into high- and low-risk groups and a nomogram was constructed and evaluated. Finally, we explore the potential functions and compared the immune landscapes of two groups. Quantitative real-time PCR was used to verify the expression of these lncRNAs. Results: Five ERS-related lncRNAs were shown to be strongly linked to patients' prognosis. A risk score model was built by using these lncRNAs to categorize patients based on their median risk scores. For LUAD patients, the model was found to be an independent prognostic predictor (p < 0.001). The signature and clinical variables were then used to construct a nomogram. With 3-year and 5-year OS' AUC of 0.725 and 0.740, respectively, the nomogram's prediction performance is excellent. The 5-lncRNA signature was associated with DNA replication, epithelial-mesenchymal transition, and the pathway of cell cycle, P53 signaling. Between the two risk groups, immune responses, immune cells, and immunological checkpoints were found to be considerably different. Conclusion: Overall, our findings indicate that the 5 ERS-related lncRNA signature was an excellent prognostic indicator and helped to predict the immunotherapy response for patients with LUAD.

Abstract
INTRODUCTION The prevalence of chronic kidney disease (CKD) rises with age and co-morbid diseases such as liver diseases. OBJECTIVES The main aim of the current meta-analysis is to assess the relationship between Non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease incidence in both diabetic and non-diabetic subjects compared with control. MATERIAL AND METHODS A systematic literature search of papers published from January 1, 2005, till April 30, 2022, found 19 studies including 1,111,046 subjects; 310,804 were diagnosed with NAFLD, and 800,242 were non-NAFLD. The measured outcome was the incidence of CKD among NAFLD subjects compared to non-NAFLD subjects in diabetic and non-diabetic subjects. Dichotomous analysis methods were used within the random effects model to calculate the odds ratio (OR) with 95% confidence intervals (95% CIs). RESULTS The incidence of CKD is highly significant in NAFLD subjects compared with controls (OR: 1.95; 95% CI: 1.65-2.31). The diabetic non-NAFLD subjects showed a significantly increased incidence of CKD compared to the non-diabetic subjects with NAFLD (OR: 1.79; 95% CI: 1.35-2.38).. In addition, the incidence of CKD was significantly higher in the NAFLD group compared with the non-NAFLD non-diabetic subjects (OR: 2.52; 95% CI: 1.91-3.32). Diabetes acts as an independent risk factor for CKD, as proven by a significant increase in incidence of diabetic subjects compared to non-diabetic NAFLD subjects (OR: 1.82; 95% CI: 1.15-2.88). CONCLUSION Non-alcoholic fatty liver disease is significantly related to an increased incidence of CKD, which is significantly higher in diabetic subjects.

Abstract
PURPOSE To investigate the safety and efficacy of ultrasound-guided renal access and tract dilation using balloon dilators, as well as to identify suitable patients for this technique. METHODS Consecutive patients undergoing ultrasound-guided PCNL using balloon dilators between December 2019 and June 2020 in seven large medical centers from China were prospectively enrolled. Demographic and perioperative parameters of the patients were collected. Logistic regression analysis was used to analyze factors that would affect the success rate of tract establishment using ultrasound-guided renal access and balloon dilation. RESULTS A total of 170 patients were included in this study, among whom, 91.18% of the (155/170) patients had a successful tract establishment under ultrasound guidance on the first attempt. The stone-free rate was 83.5% and postoperative complications occurred in 14 patients (8.23%). In univariate analysis, history of ipsilateral surgery (p = 0.026), and stone diameter (p = 0.01) were significantly associated with tract establishment failure, while a larger width of the target calyx (p = 0.016) and the presence of hydronephrosis (p = 0.001) were significantly associated with a successful tract establishment. In multivariate analysis, only hydronephrosis in target calyx (p = 0.027) was a favorable factor for successful tract establishment, and the history of ipsilateral renal surgery (p = 0.012) was the only independent risk factor for failure of tract establishment. CONCLUSION It was safe and effective to establish percutaneous renal access with balloon dilation under whole-process ultrasound monitoring during PCNL. Furthermore, patients with a hydronephrotic target calyx and without history of ipsilateral renal surgery were most suited to this technique. Trial registration CHiCTR1800014448.

Abstract
Objective To research the influence of Chinese medicine Jiedu Huayu granules (JDHY) on the immune response and inflammatory response of rats with acute liver failure (ALF) and investigate its related mechanism. Methods Rats were randomly divided into 4 groups: control group (n = 6) were injected with the same amount of normal saline; ALF group (n = 10) were injected intraperitoneally with D-GaIN (700 mg/kg) and LPS (10 μg/kg); ALF+JDHY group (n = 10) were given JDHY 57.55 g/kg/d by gavage for 7 days and injected intraperitoneally with D-GaIN/LPS after the last dose; and ALF+BAY group (n = 10) were given BAY 10 mg/kg/d by gavage for 7 days and injected intraperitoneally with D-GaIN/LPS after the last dose. Changes in liver function and coagulation function were examined in rat serum; the pathological varieties of liver tissues were verified by HE staining; immunohistochemistry was utilized to determine the ratio of PCNA and F4/80 in liver tissues; the flow cytometry was applied to determine the ratio of CD4+/CD8+ cells in peripheral blood mononuclear cells (PBMCs); ELISA and qRT-PCR were utilized to check the level of IL-10, IL-6, IL-13, IL-1β, TNF-α, IFN-γ, and CD163 in serum and liver cells. Western blot was adopted to check the expression of apoptotic protein and expression and NF-κB pathway-related protein expression. Results JDHY and BAY could decline the expression of AST, ALT, ALP, and TBiL in ALF rat serum significantly (P < 0.01), increase PTA and PLT (P < 0.01), and mitigate liver tissue damage. Besides, JDHY and BAY could reduce the apoptosis and improve the proliferation of the liver cells in rats with ALF; meanwhile, the ratio of CD4+ cells and F4/80 cells was reduced while CD8+ cells were increased (P < 0.01). Further, JDHY and BAY could reduce the level of IFN-γ, IL-6, IL-1β, and TNF-α while increasing the level of IL-10 and IL-13 (P < 0.01). Additionally, the expression of sCD163 in serum and CD163 expression in liver tissues increased (P < 0.01). The result of western blot confirmed that JDHY could inhibit the phosphorylated expression of NF-κB, IKβα, and IKKβ in the ALF rat tissues. Conclusions JDHY can upregulate the level of CD163/sCD163 by the NF-κB signaling pathway, thereby regulating immune response, inhibiting inflammatory response, and ultimately improving ALF in the rats.

Abstract
Schizophrenia is a severe psychiatric disorder with high premature mortality rates. This is a meta-analysis and systematic review of the prevalence of suicidal ideation (SI) and suicide plan (SP) among people with schizophrenia. PubMed, Web of Science, Embase, and PsycINFO were systematically searched from their respective inception to October 10, 2020. Data on prevalence of SI and/or SP were synthesized using the random effects model. Twenty-six studies covering 5079 people with schizophrenia were included for meta-analysis. The lifetime and point prevalence of SI were 34.5% (95% CI: 28.2-40.9%), and 29.9% (95% CI: 24.2-35.6%), respectively. The lifetime prevalence of SP was 44.3% and the point prevalence of SP ranged between 6.4 and 13%. Subgroup and meta-regression analyses revealed that source of patients, survey countries, and sample size were significantly associated with the point prevalence of SI, while male proportion and quality assessment scores were significantly associated with the lifetime and point prevalence of SI. Survey time and mean age were significantly associated with lifetime prevalence of SI. Both SI and SP are common in people living with schizophrenia, especially in males and inpatients. Routine screening and effective interventions for SI and SP should be implemented in this population.

Abstract
Abstract
Background
Hypertrophic cardiomyopathy (HCM) is caused by rare variants in sarcomere-encoding genes, but little is known about the clinical significance of these variants in the general population.
Purpose
To determine the population prevalence of HCM-associated sarcomeric variants, characterise their phenotypic manifestations, estimate penetrance, and identify associations between sarcomeric variants and clinical outcomes, we performed an observational study of 218,813 adults in the UK Biobank (UKBB), of whom 200,584 have whole exome sequencing (WES).
Methods
We carried out an integrated analysis of WES and cardiac magnetic resonance (CMR) imaging in UK Biobank participants stratified by sarcomere-encoding variant status. Computer vision techniques were used to automatically segment the four chambers of the heart (Figure 1). Cardiac motion analysis was used to derive strain and strain rates. Regional analysis of left ventricular wall thickness was performed using three-dimensional modelling of these segmentations.
Results
Median age at recruitment was 58 (IQR 50–63 years), and participants were followed up for a median of 10.8 years (IQR 9.9–11.6 years) with a total of 19,507 primary clinical events reported.
The prevalence of rare variants (allele frequency <0.ehab724.17314) in HCM-associated sarcomere-encoding genes in 200,584 participants was 2.9% (n=5,727; 1 in 35), and the prevalence of pathogenic or likely pathogenic variants (SARC-P/LP) was 0.24% (n=474, 1 in 423).
SARC-P/LP variants were associated with increased risk of death or major adverse cardiac events (MACE) compared to controls (HR 1.68, 95% CI 1.37–2.06, p<0.001), mainly due to heart failure endpoints (Figure 2: cumulative hazard curves with zoomed plots for lifetime risk of A) death and MACE or B) heart failure, stratified by genotype; genotype negative (SARC-NEG), carriers of indeterminate sarcomeric variants (SARC-IND) or SARC-P/LP; C) Forest plot of comparative lifetime risk of clinical endpoints by genotype).
While males had a higher overall risk of adverse outcomes, the incremental genetic risk from SARC-P/LP mutations was greater in females (HR for females: 2.18 CI 1.65–2.89, p<0.001; HR for males: 1.42 CI 1.05–1.9, p=0.02).
In 21,322 participants with CMR, SARC-P/LP were associated with asymmetric increase in left ventricular maximum wall thickness (10.9±2.7 vs 9.4±1.6 mm, p<0.001) but hypertrophy (≥13mm) was only present in 16% (n=7/43, 95% CI 7–31%). Other rare sarcomere-encoding variants had a weak effect on wall thickness (9.5±1.7 vs 9.4±1.6 mm, p=0.002) with no combined excess cardiovascular risk.
Conclusions
In the general population, SARC-P/LP variants have low aggregate penetrance for overt HCM but are associated with increased risk of adverse cardiovascular outcomes and a sub-clinical cardiomyopathic phenotype. Although absolute event rates are low, identification of these variants may enhance risk stratification beyond familial disease.

Abstract
The aim of this study was to compare the mechanical properties of three-dimensionally (3D)-printed and conventional surgical plates used for the repair of maxillary or mandibular defects under the same experimental conditions, and to provide experimental evidence for the future application and clinical trial of 3D-printed individualized surgical plates. For the experimental group, two groups of surgical plates with thicknesses of 2.0 mm and 2.5 mm were designed and 3D-printed by electron beam melting, using Ti-6Al-4V as raw material. Conventional commercially available surgical plates with the same thickness were adopted as the control group. A Vickers hardness tester and universal testing machine were used to measure the mechanical properties of the plates (hardness, bending strength, tensile strength, and yield strength). The mechanical properties of 3D-printed surgical plates were significantly better than those of conventional surgical plates of the same thickness (P < 0.001). Comparing the surgical plates of different thickness, the 2.5 mm-thick plates had the highest bending strength in the experimental group (P < 0.001) and the best hardness (P < 0.001), bending strength (P = 0.001), tensile strength (P = 0.001), and yield strength (P = 0.001) in the control group. No statistical difference was found between the two kinds of plates in the experimental group in terms of hardness (P = 0.060), tensile strength (P = 0.096), and yield strength (P = 0.496). The 3D-printed surgical plates have better mechanical properties than the conventional ones.

Abstract
OBJECTIVE This study aimed to evaluate the association between age, menopausal stage and serum anti-Müllerian hormone (AMH) levels in middle-aged women. METHODS In this cross-sectional study, the serum AMH levels of 288 healthy women aged 40-55 years (divided into age groups: 40-44, 45-49 and 50-55 years) were evaluated. Stages of Reproductive Aging Workshop + 10 criteria were used to categorize these women into menopausal stages: late reproductive, menopausal transition and early postmenopausal stages. The impact of age, menopausal stage and hormone replacement therapy on serum AMH levels was analyzed using multi-factor analysis of variance. Effects of body mass index, smoking status and oral contraceptive use were simultaneously considered. RESULTS The median AMH level was 0.140 ng/ml. Log-AMH levels varied according to age group (variance = 20.113, F = 88.538, p < 0.001) and menopausal stage (variance = 5.543, F = 24.501, p < 0.001). An exponential model defined as AMH = 227,421.757 × e(-0.301 × age) was fit to describe the decline in AMH level with age. The 5th-95th percentiles of the AMH levels ranged from less than 0.020 to 3.150, less than 0.020 to 1.944 and less than 0.020 to 0.030 ng/ml in the aforementioned menopausal stages, respectively. CONCLUSION Age and menopausal stage were associated with AMH levels; age had a greater impact on AMH than menopausal stage in middle-aged women.

Abstract
Objectives: To present our large single-center experience in the management of autosomal dominant polycystic kidney disease (ADPKD) with total ultrasound (US)-guided percutaneous nephrolithotomy (PNL) and to evaluate the role of PNL under US in these patients. Patients and Methods: We retrospectively reviewed the charts of patients with ADPKD who underwent PNL from August 2011 to December 2019. A total of 56 patients were included in this study; all procedures were completed by the total US-guided technique. Demographic characteristics, operative parameters, and postoperative data were collected and analyzed. Results: Effective renal access was achieved in all patients. The mean stone size was 3.1 cm (range 1.7-6.5 cm). The initial stone-free rate was 70.6% (36/51); five patients underwent second-look PNL to remove residual stones. The other patients underwent oral medication therapy. No severe intraoperative complications occurred; one patient received selective embolization for bleeding on the contralateral side and one patient needed percutaneous drainage for perinephric abscess. Clavien I or II complications were seen in nine patients. Renal function was improved or stable in most patients; the condition of only one patient deteriorated after surgery. Conclusion: Total US-guided PNL is a safe and efficient treatment for kidney stones in patients with ADPKD; perioperative renal function was not adversely affected and complications were acceptable compared with patients in the general population.

Abstract
Our Moroccan context is experiencing an increase in the frequency of renal tumors. This trend can be explained by the generalization of the use of imaging, in particular abdominal ultrasound, which has become almost systematic among general practitioners (Godley and Ataga, 2000 [1]). The specificity of kidney cancer is anatomopathological heterogenicity: histological type, nuclear grade, tumor stage, these elements constitute the most important prognostic factors. Renal biopsy appears to be a safe and reliable solution with a low risk of tumor seeding and complications, however it cannot provide all the detailed histological information needed. Hence the interest in the abdominal scanner. The abdominal scanner is the reference examination for the evaluation of renal tumors, it diagnoses the tumor, specifies these characteristics, it assesses the loco regional, venous extension. The objective of our study is to correlate pathological and CT findings of 70 kidney cancer in order to determine the reliability of CT in kidney cancer and its extension.

Abstract
Post-traumatic adrenal hematoma, which has rare but severe complications, is a difficult to diagnose condition. Only computed tomography, which is often performed systematically during lesional assessments of violent thoraco-abdominal trauma, can confirm the diagnosis. Symptoms are often masked by associated visceral or parietal lesions. Standard biological examinations are generally not very helpful. We will describe the case of a 47-year-old man who presented with a right adrenal hemorrhage following a road accident, for only associated lesion, a fracture of the middle arch of the first and 8th ribs, and the transverse process L1.

Abstract
OBJECTIVES To evaluate outcomes in patients who underwent total ultrasound-guided percutaneous nephrolithotomy for the management of large stones (>2 cm) within non-functioning atrophic kidneys, and to identify risk factors associated with postoperative persistence of urinary tract infection symptoms in such patients. METHODS Between December 2014 and May 2019, 56 patients with large stones within non-functioning atrophic kidneys were treated at Beijing Tsinghua Changgung Hospital, Beijing, China, with total ultrasound-guided percutaneous nephrolithotomy. Factors including age, sex, previous medical history, stone burden, stone composition, stone-free rate, complication rate and postoperative urinary tract infection symptoms were retrospectively evaluated. Uni- and multivariate analyses were carried out to identify risk factors that predict persistence of urinary tract infection symptoms after percutaneous nephrolithotomy in such patients. RESULTS The final stone-free rate after auxiliary treatments was 87.5%. The overall complication rate was 17.9%. After a median follow-up period of 12 months (range 6-40 months), three patients (5.4%) ultimately underwent nephrectomy. A total of 44 patients (78.6%) had no symptoms of urinary tract infection during follow up, whereas 63.6% of patients with diabetes continued to show persistent urinary tract infection symptoms at the latest follow up. Five patients (8.9%) showed improved total renal function, while most patients (83.9%) showed a stable estimated glomerular filtration rate. Diabetes was the only factor showing statistical significance in both univariate and multivariate analyses that predicted persistence of urinary tract infection symptoms after treatment with percutaneous nephrolithotomy. CONCLUSIONS Ultrasound-guided percutaneous nephrolithotomy is a safe and feasible procedure that can be carried out in patients with large stones within non-functioning atrophic kidneys. However, for such patients with diabetes, percutaneous nephrolithotomy is not recommended.

Abstract
OBJECTIVE Evaluation of the quality of life patients with a ureteral catheter JJ (US). METHOD This study was conducted from 01/2016 to 15/02/2017, including all patients operated on a rise of US. The USSQ questionnaire (Ureteral Stent Symptom Questionnaire) validated in French in 2010 was filled during the perioperative period with SU in place (S1), 4 weeks after putting the US (S2) and 4 weeks after removal of the US (S3), it is grouped into 6 sections: urinary symptoms, body pain, general condition, professional impact, sexuality, other problems. The Wilcoxon test was used to compare the statistical averages. RESULTS We identified 150 patients including 89 women (59.3%) and 61 men (40.7%). The average age of our patients is 49.5 years. The quality of life appeared to be significantly altered in all areas explored by the questionnaire: urinary symptoms had a mean score one week after the US rise (S1) was 29.5 versus 25.3 at four weeks after ablation (S3) of US at P<0.0001), pain persisted at four weeks after US ablation at an average S3 score of 10.6 versus 14.5 at S1 at P=0.003. The patients' EG was also altered after the placement of the SU: S1 of 16.6 versus S2 18.5 (P<0.0001), the presence of a US did not have a great impact on the activity professional active patients: active (S1 of 14.9 versus S3 of 13.3 P=0.6). But it was a sexual disability of the sexuality carrier: average score of 5.3 in S1 vs. 5.2 in S3 for a value=0.122. There is no significant difference if the US is raised urgently or in a scheduled manner. CONCLUSION US appears to have a significant impact on the quality of life of patients. LEVEL OF EVIDENCE 3.

Abstract
AIM The aim was to explore the diagnostic value of computed tomographic colonography (CTC) compared with conventional colonoscopy in individuals at high risk for colorectal cancer. METHOD PubMed, Embase, the Cochrane Library and the Web of Science were searched by two independent reviewers for potentially eligible studies published up to 31 October 2018 that were based on a per-patient analysis. stata, meta-disc and revman were used to perform this meta-analysis. A random-effect model was used, and a subgroup analysis was conducted to explore the sources of heterogeneity. RESULTS A total of 14 full-text articles, involving 3578 patients, were included in this meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and the area under the summary receiver operating characteristic curve of CTC for detecting polyps ≥ 6 mm were 0.87 (95% CI 0.83-0.90), 0.90 (95% CI 0.86-0.93), 9.08 (95% CI 6.28-13.13), 0.14 (95% CI 0.11-0.18) and 0.94 (95% CI 0.92-0.96), respectively. For polyps ≥ 10 mm, the pooled sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of CTC were 0.91 (95% CI 0.86-0.94), 0.98 (95% CI 0.95-0.99), 40.36 (95% CI 19.16-85.03), 0.90 (95% CI 0.06-0.14) and 0.98 (95% CI 0.96-0.99), respectively. CONCLUSION In this meta-analysis, CTC had high diagnostic accuracy for detecting polyps ≥ 6 mm and ≥ 10 mm in patients at high risk of developing colorectal cancer and it had a higher sensitivity and specificity for detecting polyps ≥ 10 mm than polyps ≥ 6 mm. However, the results should be used cautiously due to the significant heterogeneity.

Abstract
Objective: To investigate the relationship between exposure to famine in fetus and infant period and the risks for hypertension in adulthood. Methods: A total of 5 960 participants born between 1956 and 1965 were included in the study and were divided into unexposed group (1963-1965), fetal exposed group (1959-1961), early- childhood exposed group (1956-1958) and transitional group (1962). Logistic regression model was used to explore the association between famine exposure in early life and the risk for hypertension in adulthood. Results: Both the fetal exposure and the early-childhood exposure were the risk factors for hypertension in adulthood (OR=1.249, 95%CI: 1.049-1.486 and OR=1.360, 95%CI: 1.102-1.679). Meanwhile, in rural area, compared with unexposed group, the fetal exposure (OR=1.401, 95%CI: 1.091-1.798) and the early-childhood exposure (OR=1.460, 95%CI: 1.145-1.862) were also associated with a greater risk of hypertension in adulthood. In addition, fetal exposure and early-childhood exposure to famine in women were associated with 36.0% and 31.9% increased risks for hypertension (95%CI: 7.8%-71.7% and 95%CI: 4.8%-66.0%) according to the stratified analysis. Conclusion: Fetal exposure to famine might increase the risk for hypertension in adulthood.

Abstract
Objective: To analyzed the clinical characteristics and prognosis of patients with H7N9 avian influenza. Methods: The baseline characteristics, clinical manifestations, treatments, laboratory and imaging findings were collected and analyzed for 20 patients with H7N9 avian influenza admitted to the First Affiliated Hospital of Nanchang University from December 2016 to March 2017. According to the final clinical outcome, the patients were divided into the death group and the survival group. Ten patients in the death group died, and 10 patients in the survival group were discharged. The data with normal distribution were analyzed by t test. The data with non-normal distribution were analyzed by Wilcoxon rank sum test. Results: Of the 20 patients, 13 were males and 7 were females, aging 40-82 years, with a mean age of (60±12) years. Twelve patients had a definite history of poultry exposure and 10 had chronic underlying diseases such as hypertension and diabetes. The clinical manifestations were mainly fever, cough, hemoptysis, respiratory distress, fatigue, etc. In the survival group, the platelet count was(167-315)×10(9)/L, while it was (78-152)×10(9)/L in the death group. The average white blood cell count was (7.78-11.52)×10(9)/L and (9.91-15.93)×10(9)/L in the survival and death groups respectively. The average value of lymphocyte count was (0.69-1.59)×10(9)/L and (0.58-0.86)×10(9)/L in the survival and death groups respectively. In the death group the glutamic-pyruvic transaminase (ALT) value was (14.0-352.0) U/L, the total bilirubin value was (6.9-34.5) μmol/L, the creatine kinase MB (CK-MB) was (16.0-162.0) U/L, the serum calcium value was (1.4-2.0) mmol/L, the C-reactive protein value was (33.1-414.0) mg/L, and the calcium reduction prime value was (0.6-100.0) μg/L. In the survival group,the ALT value was (25.0-181.0) U/L, the total bilirubin value was (4.8-25.9) μmol/L, the CK-MB value was (15.0-40.0) U/L, the serum calcium value was (1.9-2.4) mmol/L, the C-reaction protein value was (12.8-52.5) mg/L, and the procalcitonin value was (0.3-23.3) μg/L. Sixteen cases suffered severe pneumonia. Twelve patients received extracorporeal membrane oxygenation (ECMO), and 4 survived. The cause of death was mainly related to factors such as age, chronic underlying diseases and severity of illness. Conclusions: Human infection with H7N9 avian influenza virus was highly pathogenic, and prone to progress into severe pneumonia, with a high mortality. Decreased platelet count was associated with mortality (t=4.07, P=0.001), predictive of patient outcome.

Abstract
BACKGROUND AND PURPOSE The efficacy and safety of transvenous embolization for brain arteriovenous malformations remains unclear, given the very limited number of cases reported. This prospective study was performed to assess this technique in ruptured AVMs. MATERIALS AND METHODS Twenty-one consecutive patients with ruptured brain AVMs who underwent transvenous embolization were prospectively followed between November 2016 and November 2018. The Spetzler-Martin grade was I in 3 AVMs (14.3%), II in four (19.0%), III in eleven (52.4%), and IV in three (14.3%). The complete AVM occlusion rate was calculated from 6-month follow-up DSA images. Occurrence of hemorrhage and infarction after embolization was evaluated using CT and MR imaging within 1 month after the operation. The mRS was used to assess the functional outcomes. RESULTS Complete AVM nidus obliteration was shown in 16 (84%) of 19 patients with technically feasible AVMs immediately after embolization. One (5%) patient with a small residual nidus after treatment showed complete obliteration at 13-month follow-up. There were 5 hemorrhages and 1 infarction; 4 patients' symptoms improved gradually. The percentage of cases with mRS ≤ 2 rose from 57.1% (12/21) before embolization to 66.7% (14/21) at 1-month follow-up. Both the morbidity and mortality rates were 4.8% (1/21). CONCLUSIONS Transvenous embolization can be performed only in highly selected hemorrhagic brain AVMs with high complete obliteration rates, improved functional outcomes, and acceptable morbidity and mortality rates, but it should not be considered as a first-line treatment.

Abstract
Cdh1 is a regulatory subunit of the anaphase promoting complex/cyclosome (APC/C), known to be involved in regulating neuronal survival. The role of Cdh1 in volatile anesthetics-induced neuronal apoptosis in the developing brain is unknown. In this study, we used postnatal day 7 (P7) and day 21 (P21) mice exposed to 2.3% sevoflurane for 6 h to investigate at which age and duration of exposure sevoflurane affects the expression of Cdh1 and glycolytic enzyme 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) and that of the pentose phosphate pathway (PPP) enzyme, glucose-6-phosphate dehydrogenase (G6PD). Furthermore, we tested whether the cyclin-dependent kinases (cdks) inhibitor roscovatine could counteract the effects caused by exposure to sevoflurane. Finally, we applied the glycolysis inhibitor 3-(3-pyridinyl)-1-(4-pyridinyl)-2-propen-1-one (3-PO), G6PD inhibitor dehydroepiandrosterone (DHEA), and exogenous reduced glutathione to examine the contribution of the glycolysis pathway and PPP to sevoflurane-induced neuroapoptosis. We found that prolonged sevoflurane anesthesia significantly reduces the Cdh1 level in P7 mice compared to in the P21 ones; moreover, the decrease in Cdh1 level results in a switch in glucose metabolism from the PPP to neuronal glycolysis. This leads to an imbalance between reactive oxygen species production and reduced glutathione level in the developing brain, which is more susceptible to oxidative stress. As a result, sevoflurane induces neuroapoptosis through Cdh1-mediated glucose metabolism reprogramming. Our study demonstrates a critical role of Cdh1 in sevoflurane-induced neuroapoptosis by shifting PPP to the glycolytic pathway in the developing brain. These findings suggest that Cdh1 may be a novel target for preventing volatile anesthetics-induced neurotoxicity and memory impairment.

Abstract
Lung cancer is the leading cause of cancer-associated mortality worldwide. Previous studies have demonstrated that long non-coding RNAs (lncRNAs) serve important roles in diverse biological processes. However, the molecular function and prognostic value of the majority of lncRNAs in non-small cell lung cancer (NSCLC) remain unknown. The present study investigated the expression of the lncRNA GABPB1 intronic transcript (GABPB1-IT1) in NSCLC tissues using publicly available databases. Subsequently, protein-protein interaction (PPI) and co-expression networks were constructed to identify key targets of lncRNA GABPB1-IT1. Furthermore, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to investigate the potential roles of lncRNA GABPB1-IT1. The current study identified that the expression of GABPB1-IT1 was significantly downregulated in NSCLC samples compared with normal samples. Furthermore, the expression levels of GABPB1-IT1 were lower in high grade NSCLC samples compared with low grade NSCLC samples. Additionally, overexpression of GABPB1-IT1 in cancer samples was associated with improved survival of patients with NSCLC. GABPB1-IT1 was revealed to be involved in the regulation of cell cycle-associated biological processes, including sister chromatid cohesion, mitotic nuclear division, DNA replication, chromosome segregation, G1/S transition of mitotic cell cycle, mitotic cytokinesis and cell division. Finally, a GABPB1-IT1-associated protein-protein interaction network was constructed for NSCLC. To the best of our knowledge, the present study was the first to demonstrate that GABPB1-IT1 is associated with the prognosis of NSCLC. The current study provides useful information to assist with the investigation of potential candidate biomarkers for diagnosis, prognosis and drug targets for NSCLC.

Abstract
The shaking table based on electro-hydraulic servo parallel mechanism has the advantage of strong carrying capacity. However, the strong coupling caused by the eccentric load not only affects the degree of freedom space control precision, but also brings trouble to the system control. A novel decoupling control strategy is proposed, which is based on modal space to solve the coupling problem for parallel mechanism with eccentric load. The phenomenon of strong dynamic coupling among degree of freedom space is described by experiments, and its influence on control design is discussed. Considering the particularity of plane motion, the dynamic model is built by Lagrangian method to avoid complex calculations. The dynamic equations of the coupling physical space are transformed into the dynamic equations of the decoupling modal space by using the weighted orthogonality of the modal main mode with respect to mass matrix and stiffness matrix. In the modal space, the adjustments of the modal channels are independent of each other. Moreover, the paper discusses identical closed-loop dynamic characteristics of modal channels, which will realize decoupling for degree of freedom space, thus a modal space three-state feedback control is proposed to expand the frequency bandwidth of each modal channel for ensuring their near-identical responses in a larger frequency range. Experimental results show that the concept of modal space three-state feedback control proposed in this paper can effectively reduce the strong coupling problem of degree of freedom space channels, which verify the effectiveness of the proposed model space state feedback control strategy for improving the control performance of the electro-hydraulic servo plane redundant driving mechanism.

Abstract
BACKGROUND AND PURPOSE Although flow diverters have been reported with favorable clinical and angiographic outcomes in various literatures, randomized trials determining their true effectiveness and safety are still in lack. The Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter (PARAT) trial was designed to evaluate the safety and efficacy of the Tubridge flow diverter in the treatment of large or giant aneurysms in comparison with Enterprise stent-assisted coiling. MATERIALS AND METHODS This prospective, multicenter, randomized trial was conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent-assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel-related stroke, aneurysm bleeding, in-stent stenosis, parent artery occlusion, and the frequency of all adverse events. RESULTS Among 185 enrolled subjects, 41 withdrew before procedure initiation. Overall, 82 subjects underwent Tubridge implantation, and 62 subjects were primarily treated with stent-assisted coiling. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively, with a calculated common odds ratio of 9.4 (95% confidence interval, 4.14-21.38; P < .001). There was a higher, nonsignificant frequency of complications for Tubridge subjects. Multivariate analysis showed a decreased stroke rate at the primary investigational site, with a marginal P value (P = .051). CONCLUSIONS This trial showed an obviously higher rate of large and giant aneurysm obliteration with the Tubridge FD over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications. Investigational site comparisons suggested that a learning curve for flow-diverter implantation should be recognized and factored into trial designs.

Abstract
Which temporal features that can characterize different brain states (i.e., consciousness or unconsciousness) is a fundamental question in the neuroscience of consciousness. Using resting-state functional magnetic resonance imaging (rs-fMRI), we investigated the spatial patterns of two temporal features: the long-range temporal correlations (LRTCs), measured by power-law exponent (PLE), and temporal variability, measured by standard deviation (SD) during wakefulness and anesthetic-induced unconsciousness. We found that both PLE and SD showed global reductions across the whole brain during anesthetic state comparing to wakefulness. Importantly, the relationship between PLE and SD was altered in anesthetic state, in terms of a spatial "decoupling." This decoupling was mainly driven by a spatial pattern alteration of the PLE, rather than the SD, in the anesthetic state. Our results suggest differential physiological grounds of PLE and SD and highlight the functional importance of the topographical organization of LRTCs in maintaining an optimal spatiotemporal configuration of the neural dynamics during normal level of consciousness. The central role of the spatial distribution of LRTCs, reflecting temporo-spatial nestedness, may support the recently introduced temporo-spatial theory of consciousness (TTC).

Abstract
OBJECTIVES To investigate the effects of black cohosh and estrogen on the temperature in ovariectomized rats, the core body temperature (CBT) and tail-skin temperature (TST) were simultaneously monitored and the relationship between these two temperatures was explored. METHODS Twenty-four female Sprague-Dawley rats aged 8 weeks were randomly divided into four groups: sham-operated (SHAM), ovariectomized (OVX), OVX treated with estradiol valerate (OVX + E), and OVX treated with isopropanolic black cohosh extract (OVX + ICR). Rats were sham-operated or ovariectomized and were implanted with telemetry transmitters with dual thermistor probes. Two weeks after surgery, the animals were treated with drugs for 4 weeks. During the last week of the treatments, the dynamic temperature profiles of the CBT and TST were collected. RESULTS The average CBT and TST, TST fluctuation frequency, and the average amplitude fluctuation were significantly higher in OVX than in SHAM rats. In addition, dramatic fluctuations of TST in OVX rats occurred at the time points of the day when the CBTs were lower in OVX rats than in SHAM rats. Treatment of OVX rats with estradiol valerate or isopropanolic black cohosh extract markedly decreased the average CBT and TST, TST fluctuation frequency, and the average amplitude fluctuation. Moreover, CBT was found to be significantly higher, while TST was lower in OVX + E than in OVX + ICR rats. CONCLUSIONS Both black cohosh and estradiol treatments ameliorated the abnormal thermoregulation in OVX rats. In particular, black cohosh reduced CBT better than estradiol and estradiol reduced TST better than black cohosh.

Abstract
Oryza longistaminata originates from African wild rice and contains valuable traits conferring tolerance to biotic and abiotic stress. However, interspecific crosses between O. longistaminata and Oryza sativa cultivars are hindered by reproductive barriers. To dissect the mechanism of interspecific hybrid sterility, we developed a near-isogenic line (NIL) using indica variety RD23 as the recipient parent and O. longistaminata as the donor parent. Both pollen and embryo sac semi-sterility were observed in F1 hybrids between RD23 and NIL. Cytological analysis demonstrated that pollen abortion in F1 hybrids occurred at the early bi-nucleate stage due to a failure of the first mitosis in microspores. Partial embryo sacs in the F1 hybrids were defective during the functional megaspore formation stage. Most notably, nearly half of the male or female gametes were aborted in heterozygotes S40iS40l, regardless of their genotypes. Thus, S40 was indicated as a one-locus sporophytic sterility gene controlling both male and female fertility in hybrids between RD23 and O. longistaminata. A population of 16 802 plants derived from the hybrid RD23/NIL-S40 was developed to fine-map S40. Finally, the S40 locus was delimited to an 80-kb region on the short arm of chromosome 1 in terms with reference sequences of cv. 93-11. Eight open reading frames (ORFs) were localized in this region. On the basis of gene expression and genomic sequence analysis, ORF5 and ORF8 were identified as candidate genes for the S40 locus. These results are helpful in cloning the S40 gene and marker-assisted transferring of the corresponding neutral allele in rice breeding programs.

Abstract
Tau is a microtubule-associated protein, and the oligomeric and hyperphosphorylated forms of tau are increased significantly after neurotrauma and considered important factors in mediating cognitive dysfunction. Blockade of adenosine A2A receptors, either by caffeine or gene knockout (KO), alleviates cognitive dysfunction after traumatic brain injury (TBI). We postulated that A2AR activation exacerbates cognitive impairment via promoting tau hyperphosphorylation. Using a mouse model of moderate controlled cortical impact, we showed that TBI induced hyperphosphorylated tau (p-tau) in the hippocampal dentate gyrus and spatial memory deficiency in the Morris water maze test at 7 days and 4 weeks after TBI. Importantly, pharmacological blockade (A2AR antagonist ZM241385 or non-selective adenosine receptor antagonist caffeine) or genetic inactivation of A2ARs reduced the level of tau phosphorylation at Ser404 and alleviated spatial memory dysfunction. The A2AR control of p-tau is further supported by the observations that a KO of A2AR decreased the activity of the tau phosphorylation kinases, glycogen synthase kinase-3β (GSK-3β) and protein kinase A (PKA) after TBI, and by that CGS21680 (A2AR agonist) exacerbated okadaic acid-induced tau hyperphosphorylation in cultured primary hippocampal neurons. Lastly, CGS21680-induced neuronal tau hyperphosphorylation and axonal injury were effectively alleviated by individual treatments with ZM241385 (A2AR antagonist), H89 (PKA antagonist) and SB216763 (GSK-3β antagonist), or by the combined treatment with H89 and SB216763. Our findings suggest a novel mechanism whereby A2AR activation triggers cognitive dysfunction by increasing the phosphorylation level of tau protein after TBI and suggest a promising therapeutic and prophylactic strategy by targeting aberrant A2AR signaling via tau phosphorylation.

Abstract
OBJECTIVE To compare the fracture resistance of roots of mandibular premolar with different apical preparation diameters. METHODS Sixty single-rooted single canal permanent mandibular premolar teeth extracted newly for orthodontic reason without immatureness, fracture or cracks were selected, with a curvature less than 10°, and internal length: short diameter of less than 2 at a level 5 mm from the apex. All the teeth were decoronated, leaving roots 13 mm in length. The initial apical file size for the teeth was ≤15#. The roots were assigned to 6 groups based on weights with random block design. Group A: blank control group, no instrumentation was performed. Groups B-F: the master apical file (MAF) was 40#, 45#, 50#, 55# and 60#, respectively. In the five experimental groups the roots were instrumented using hand files with step-back technique at 1 mm increments, resulting in a taper of 0.05. The irrigant used was distilled water. After mounted in acrylic resin, all the teeth were subject to vertical loading using an Instron testing machine until fractured. The occurrence of fractures was detected when the applied load suddenly decreased. The fracture load values and fracture modes were recorded. One-way ANOVA and post-hoc Tukey test were used to determine the difference of fracture load values between the groups (P<0.05). Chi-square tests were used to compare the modes of root fracture. RESULTS Five experimental groups exhibited lower fracture load values than that of control group [(1 444±155) N]. The mean fracture load values for roots instrumented to an apical diameter of 50# [(1 027±128) N], 55# [(994±150) N] and 60# [(983±166) N] were significantly lower than that of control group and 40# group [(1 339±131) N] and 45# [(1 287±144) N] (P<0.05). Buccal-lingual fracture, mesio-distal fracture and compound fracture occurred 55%, 13% and 32%, respectively. No difference of fracture mode was detected in the six groups. CONCLUSION The fracture resistance reduced significantly when the roots were instrumented to an apical diameter of 50# or larger.

Abstract
OBJECTIVE This study aimed to evaluate the effect of health education combining diet and exercise supervision on menopausal symptoms and diet/exercise habits. METHODS The randomized controlled study enrolled 60 patients with perimenopausal syndrome (Kupperman Menopause Index (KMI) score ≥15). The participants were randomized into either an intervention group (n = 30) or a control group (n = 30). Women were interviewed with questionnaires about perimenopausal symptoms, diet pattern and exercise habit. Their height and weight were measured. Women in the intervention group received health education, diet supervision and exercise supervision twice a week while those in the control group continued as normal. The total KMI score, scores of individual symptoms, diet pattern and exercise habit were measured after intervention. RESULTS The total KMI score, the individual KMI scores for paresthesia, irritability, depression/suspicious, fatigue, arthralgia/myalgia, and palpitations of the intervention group were significantly lower compared with the control group after intervention. The intake of cereal, meat, fats and oils of the intervention group were significantly lower at week 12 compared with baseline. The percentage of women with a regular exercise habit was significantly higher in the intervention group than in the control group after intervention. CONCLUSIONS Twelve weeks intervention of health education combining diet and exercise supervision could improve perimenopausal symptoms and help the patients establish good living habits.

Abstract
In this paper, we examine a laser-based approach to remotely initiate, measure, and differentiate acoustic and vibrational emissions from trace quantities of explosive materials against their environment. Using a pulsed ultraviolet laser (266 nm), we induce a significant (>100 Pa) photoacoustic response from small quantities of military-grade explosives. The photoacoustic signal, with frequencies predominantly between 100 and 500 kHz, is detected remotely via a wideband laser Doppler vibrometer. This two-laser system can be used to rapidly detect and discriminate explosives from ordinary background materials, which have significantly weaker photoacoustic response. A 100 ng/cm2 limit of detection is estimated. Photoablation is proposed as the dominant mechanism for the large photoacoustic signals generated by explosives.

Abstract
Adiponectin, a cytokine secreted typically by adipocytes, has been implicated as a molecular switch between female reproduction and energy balance. The present study was undertaken to investigate the expression of adiponectin system and patterns of genes in the hypothalamic-pituitary-ovary (HPO) axis of food-restricted pre-pubertal ewes. Eighteen 2-month-old female ewes were assigned to 3 groups after a pre-feeding ad libitum for 10 days (six in each group): the control group (C), the low-food-restricted group (LR) and the high-food-restricted group (HR), which were fed with 100%, 70% and 50% of ad libitum food intake, respectively. The hypothalamus, pituitary, ovary and serum were collected after food restriction for 2 months. Results by ELISA showed that food restriction increased serum adiponectin concentrations. Quantitative real-time PCR showed that the gene transcriptions for adiponectin receptor 1 (AdipoR1) and 2 (AdipoR2) were enhanced in the hypothalamic-pituitary-ovarian (HPO) axis, while KISS-1/GPR-54 and gonadotropin-releasing hormone (GnRH) in the hypothalamus and luteinizing hormone β-subunit (LHβ) and follicle-stimulating hormone β-subunit (FSHβ) in the pituitary were reduced after food restriction. Immunohistochemistry results demonstrated that AdipoR1 localized in the oocytes of follicles in the ovary. These results suggest that the alterations in the expression of adiponectin and its receptors in response to food restriction might negatively influence the HPO axis.
