Abstract
OBJECTIVES The association between blood pressure and frailty outcome in the middle-aged and older population remains controversial. This study aimed to examine the relationship between trajectories of systolic blood pressure (SBP) and new-onset frailty. DESIGN Cohort study with a 7-year follow-up. SETTING AND PARTICIPANTS Data were derived from 4 waves (2011, 2013, 2015 and 2018) of the China Health and Retirement Longitudinal Study and 6168 participants aged ≥45 years were included in the study. METHODS The frailty index (FI) was constructed based on 40 scored items, with FI ≥ 0.25 defined as frailty. We identified the 5-year trajectory of SBP by latent class trajectory modeling. The association between SBP trajectories and frailty was explored based on hazard ratios (HR) by four Cox proportional hazards models. Furthermore, we also investigated the relationship between mean SBP and systolic blood pressure variability (SBPV) and frailty. RESULTS 6168 participants were included in this study with a mean age of 59 years. We identified five trajectories based on SBP, which are maintained low-stable SBP (T0), moderate-stable SBP (T1), remitting then increasing SBP (T2), increasing then remitting SBP (T3), and remaining stable at high SBP levels (T4). During the 7-year follow-up period, frailty outcome occurred in 1415 participants. After adjusting for other confounders, the two trajectories labeled "T2" and "T4" were associated with a higher risk of frailty compared with T0. In addition, elevated SBP and increased SBPV were associated with risk of frailty. CONCLUSIONS Higher risk of frailty occurred in two trajectories, remitting then increasing and remaining stable at high SBP levels, were associated with a relatively higher risk of frailty.

Abstract
Endocrine therapy is the primary systemic therapy for hormone receptor-positive breast cancer, which runs through the whole process of treatment for early and metastatic breast cancer. The development of new endocrine agents and targeted drugs such as cyclin-dependent kinases 4/6(CDK4/6)inhibitors has improved outcome of patients with hormone receptor-positive breast cancer and changed the treatment landscape. The update of clinical research data provides more treatment options, calling for treatment optimization. Experts had a deep discussion around the hot topics on endocrine therapy of breast cancer, and formulated the'Expert consensus on endocrine therapy of breast cancer (2023 edition)'.This consensus is based on research data worldwide and clinical practice experience, with the aims of standardizing clinical diagnosis and optimizing treatment in neoadjuvant, adjuvant and metastatic setting of hormone receptor-positive breast cancer.

Abstract
Treatment of irritable bowel syndrome (IBS) remains challenging for clinicians. Probiotic fungi may act as candidate options for IBS treatment, but systematic evaluation of their clinical value remains scarce. This study is aimed to assess the efficacy and the safety of probiotic fungi for IBS treatment by means of systematic review and meta-analysis. PubMed, Embase, Web of Science, and the Cochrane Library, were searched up to June 2022. Randomised controlled trials recruited subjects with prescriptions of probiotic fungi were eligible. Efficacy and safety of probiotic fungi were re-evaluated. Continuous data were pooled to obtain standardised difference in means (SMD) with a 95% confidence interval. The search strategy identified 120 articles of which 7 trial assessing 883 subjects were included in the analysis. Systematic data support that Saccharomyces helps to relieve abdominal pain/discomfort (SMD = -0.205, P = 0.005), and presented potential improvements on psychological outcomes, stool form for IBS patients. It is hard to demonstrate favourable effects on other symptoms (including distension, mucus passage, sense of incomplete evacuation, urgency, straining). The incidence of mild complications ranged from 0 to 51.4%, but no serious complications were observed in the included trials. Therefore, the partial response and the relative safe of probiotic fungi for IBS treatment have been demonstrated from the existing trials. However, it is premature to eventually declare the practical effects of probiotic fungi. Conducting more high-quality and large-scale trials and real-world studies, or even developing new fungal strains, is still necessary.

Abstract
Objective: To investigate the clinicopathological features, immunophenotype and prognosis of nuclear protein in testis (NUT) midline carcinoma. Methods: Twenty-four resection cases of NUT midline carcinoma diagnosed at the Department of Pathology, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China from January 2018 to September 2022, were collected, and retrospectively analyzed for their clinicopathological characteristics. Relevant literature was reviewed. Results: All 24 cases of NUT midline carcinoma occurred in the chest or head and neck, including 14 men and 10 women, with a median age of 40 years. Histological examination showed that the tumors were poorly differentiated, with solid nested or sheet-like arrangement, small to medium-sized cells, sparse cytoplasm and coarse granular chromatin, including 5 cases with abrupt squamous epithelial differentiation. Immunohistochemistry showed that all 24 cases were positive for NUT protein, while 16 cases were p63 positive, 19 cases were p40 positive, 15 out of 18 cases were CK5/6 positive. Follow-up data were obtained for 21 patients (follow-up time range, 1-21 months), of which 11 survived, 10 died, and 3 were lost to follow-up. Conclusions: NUT midline carcinoma is a rare and highly aggressive malignancy with unique histological, immunophenotypic and molecular features. It has a poor prognosis.

Abstract
BACKGROUND Endometrial cancer (EC) is one of the most common gynecological malignancies globally, and the development of innovative, effective drugs against EC remains a key issue. Phytoestrogen kaempferol exhibits anti-cancer effects, but the action mechanisms are still unclear. METHOD MTT assays, colony-forming assays, flow cytometry, scratch healing, and transwell assays were used to evaluate the proliferation, apoptosis, cell cycle, migration, and invasion of both ER-subtype EC cells. Xenograft experiments were used to assess the effects of kaempferol inhibition on tumor growth. Next-generation RNA sequencing was used to compare the gene expression levels in vehicle-treated versus kaempferol-treated Ishikawa and HEC-1-A cells. A network pharmacology and molecular docking technique were applied to identify the anti-cancer mechanism of kaempferol, including the building of target-pathway network. GO analysis and KEGG pathway enrichment analysis were used to identify cancer-related targets. Finally, the study validated the mRNA and protein expression using real-time quantitative PCR, western blotting, and immunohistochemical analysis. RESULTS Kaempferol was found to suppress the proliferation, promote apoptosis, and limit the tumor-forming, scratch healing, invasion, and migration capacities of EC cells. Kaempferol inhibited tumor growth and promotes apoptosis in a human endometrial cancer xenograft mouse model. No significant toxicity of kaempferol was found in human monocytes and normal cell lines at non-cytotoxic concentrations. No adverse effects or significant changes in body weight or organ coefficients were observed in 3-7 weeks' kaempferol-treated animals. The RNA sequencing, network pharmacology, and molecular docking approaches identified the overall survival-related differentially expressed gene HSD17B1. Interestingly, kaempferol upregulated HSD17B1 expression and sensitivity in ER-negative EC cells. Kaempferol differentially regulated PPARG expression in EC cells of different ER subtypes, independent of its effect on ESR1. HSD17B1 and HSD17B1-associated genes, such as ESR1, ESRRA, PPARG, AKT1, and AKR1C1\2\3, were involved in several estrogen metabolism pathways, such as steroid binding, 17-beta-hydroxysteroid dehydrogenase (NADP+) activity, steroid hormone biosynthesis, and regulation of hormone levels. The molecular basis of the effects of kaempferol treatment was evaluated. CONCLUSIONS Kaempferol is a novel therapeutic candidate for EC via HSD17B1-related estrogen metabolism pathways. These results provide new insights into the efficiency of the medical translation of phytoestrogens.

Abstract
Objective: To investigate the regulatory effects of bio-intensity electric field on directional migration and microtubule acetylation in human epidermal cell line HaCaT, aiming to provide molecular theoretical basis for the clinical treatment of wound repair. Methods: The experimental research methods were used. HaCaT cells were collected and divided into simulated electric field group (n=54) placed in the electric field device without electricity for 3 h and electric field treatment group (n=52) treated with 200 mV/mm electric field for 3 h (the same treatment methods below). The cell movement direction was observed in the living cell workstation and the movement velocity, trajectory velocity, and direction of cosθ of cell movement within 3 h of treatment were calculated. HaCaT cells were divided into simulated electric field group and electric field treatment 1 h group, electric field treatment 2 h group, and electric field treatment 3 h group which were treated with 200 mV/mm electric field for corresponding time. HaCaT cells were divided into simulated electric field group and 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group treated with electric field of corresponding intensities for 3 h. The protein expression of acetylated α-tubulin was detected by Western blotting (n=3). HaCaT cells were divided into simulated electric field group and electric field treatment group, and the protein expression of acetylated α-tubulin was detected and located by immunofluorescence method (n=3). Data were statistically analyzed with Kruskal-Wallis H test,Mann-Whitney U test, Bonferroni correction, one-way analysis of variance, least significant difference test, and independent sample t test. Results: Within 3 h of treatment, compared with that in simulated electric field group, the cells in electric field treatment group had obvious tendency to move directionally, the movement velocity and trajectory velocity were increased significantly (with Z values of -8.53 and -2.05, respectively, P<0.05 or P<0.01), and the directionality was significantly enhanced (Z=-8.65, P<0.01). Compared with (0.80±0.14) in simulated electric field group, the protein expressions of acetylated α-tubulin in electric field treatment 1 h group (1.50±0.08) and electric field treatment 2 h group (1.89±0.06) were not changed obviously (P>0.05), while the protein expression of acetylated α-tubulin of cells in electric field treatment 3 h group (3.37±0.36) was increased significantly (Z=-3.06, P<0.05). After treatment for 3 h, the protein expressions of acetylated α-tubulin of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group were 1.63±0.05, 2.24±0.08, and 2.00±0.13, respectively, which were significantly more than 0.95±0.27 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of acetylated α-tubulin in 200 mV/mm electric field group and 300 mV/mm electric field group were increased significantly (P<0.01); the protein expression of acetylated α-tubulin of cells in 300 mV/mm electric field group was significantly lower than that in 200 mV/mm electric field group (P<0.05). After treatment for 3 h, compared with that in simulated electric field group, the acetylated α-tubulin of cells had enhanced directional distribution and higher protein expression (t=5.78, P<0.01). Conclusions: Bio-intensity electric field can induce the directional migration of HaCaT cells and obviously up-regulate the level of α-ubulin acetylation after treatment at 200 mV/mm bio-intensity electric field for 3 h.

Abstract
Chiral materials have attracted significant research interests as they exhibit intriguing physical properties, such as chiral optical response, spin-momentum locking, and chiral induced spin selectivity. Recently, layered transition metal dichalcogenide 1T-TaS_{2} has been found to host a chiral charge density wave (CDW) order. Nevertheless, the physical consequences of the chiral order, for example, in electronic structures and the optical properties, are yet to be explored. Here, we report the spectroscopic visualization of an emergent chiral electronic band structure in the CDW phase, characterized by windmill-shaped Fermi surfaces. We uncover a remarkable chirality-dependent circularly polarized Raman response due to the salient in-plane chiral symmetry of CDW, although the ordinary circular dichroism vanishes. Chiral Fermi surfaces and anomalous Raman responses coincide with the CDW transition, proving their lattice origin. Our Letter paves a path to manipulate the chiral electronic and optical properties in two-dimensional materials and explore applications in polarization optics and spintronics.

Abstract
Abstract
The flow behavior and formability of Al-Li alloys under warm forming conditions are complicated because they depend on several factors, such as the deformation mode, strain, and strain rates. Therefore, characterizing the mechanical response, and deformation behavior of AA2060-T8 sheets under a wide range of temperatures and strain rates is crucial to develop a new thermo-mechanical processing (TMP) route for their wide industrial applications. Furthermore, determining the activation energy (Q) and predicting the flow behaviour of AA2060-T8 sheets under warm forming temperatures is meaningful for characterizing the mechanical response of AA2060-T8 sheets at warm deformation conditions. Thus, in this study, the Arrhenius constitutive model is developed to investigate the influence of strain rate and temperature on the warm deformation behaviour of AA2060-T8 and determine the activation energy (Q) of AA2060-T8, which is a crucial physical parameter to estimate the difficulties of deforming AA2060-T8 sheets under warm forming conditions.

Abstract
China was certificated malaria-free by WHO in 2021 and has continued to maintain malaria elimination. However, there are still huge challenges in malaria control in the border regions between Yunnan Province, China and Myanmar due to lack of geographic barriers and frequent cross-border travel. Hereby, we review the direction contributions of the Global Fund Malaria Program implemented by Health Poverty Action (HPA), an international non-governmental organization (NGO), to malaria elimination in China, and analyze the challenges of malaria control caused by external environmental factors, such as COVID-19, in regions where the Global Fund Malaria Program is implemented. In addition, some suggestions are proposed for cross-border collaboration on malaria control.

Abstract
Objective: To investigate the expression levels and clinical significance of glioma-associated oncogene homolog 1 (GLI1) and sonic hedgehog signaling molecule (Shh) in the malignant transformation of ovarian endometriosis (EM). Methods: The expressions of GLI1 and Shh were detected by real-time reverse transcription (RT)-polymerase chain reaction (PCR) and EnVision method in 50 cases of ovarian EM tissues, 35 cases of atypical endometriosis (aEM) and 50 cases of endometriosis-associated ovarian cancer (EAOC). The expression differences of two molecular markers in the malignant transformation of ovarian EM were compared, and the relationships between two molecular markers and the clinicopathological features and prognosis of EAOC were analyzed. Results: (1) RT-PCR showed that the expression levels of GLI1 mRNA in EM, aEM and EAOC group were 1.77±0.40, 3.54±0.44, and 7.80±0.24, respectively. The expression levels of Shh mRNA were 0.95±0.21, 3.14±0.35, and 5.41±0.31, respectively. GLI1 and Shh mRNA in EAOC group were significantly higher than those in EM and aEM group (all P<0.01), and there were statistically significant differences between EM and aEM group (all P<0.01). The percentages of GLI1 in ovarian EM, aEM and EAOC were 32% (16/50), 57% (20/35), and 66% (33/50), respectively, meanwhile, the positive expression rates of Shh were 20% (10/50), 49% (17/35), and 54% (27/50), respectively (all P<0.01). GLI1 mRNA expression was positively correlated with Shh mRNA expression in EAOC tissues (r=0.721, P<0.01). The expressions of GLI1 protein were proportionated to Shh protein in EAOC tissues (r=0.608,P=0.001). (2) The expression of GLI1 was significantly related to the International Federation of Gynecology and Obstetrics (FIGO) stage, cancer antigen 125 (CA125) levels, lymph node metastasis, and Platinum resistance in EAOC patients (all P<0.05). The expression of Shh were related to FIGO stage and lymph node metastasis in EAOC patients (all P<0.05). Logistic regression analysis showed that GLI1 expression was an independent risk factor for poor prognosis in EAOC patients (P<0.05). Kaplan-meier survival analysis showed that the overall survival rate of EAOC patients with high GLI1 expression and low GLI1 expression was 12.1% and 35.3%, respectively, with statistical significance (χ²=10.73, P<0.01). The overall survival rate of EAOC patients with high and low expression of Shh protein was 11.1% and 30.4%, in which there was statistically significant difference (χ²=3.96, P=0.047). Conclusion: GLI1 and Shh are highly associated with the malignant transformation of ovarian EM, which may play a role in promoting malignant degeneration of ovarian EM, and the high expression of GLI1 and Shh indicates a poor prognosis in EAOC patients.

Abstract
Abstract Objective To study the genetic polymorphism of whole mitochondrial DNA (mtDNA) genomes in She population in Zhejiang and to explore the maternal genetic structure of the She population. Methods Whole mtDNA genomes of 231 unrelated individuals from She population in Zhejiang Province were sequenced. The number of mutations and population genetics parameters such as, the haplotype diversity (HD), discrimination power (DP), and random match probabilities (RMP) were analyzed. The mtDNA haplogroups of Zhejiang She population were classified, and the maternal genetic relationships between She and nine other Chinese populations were estimated. Results In 231 Zhejiang She samples, 8 507 mutations (702 types) were observed and the samples were classified into 94 haplogroups. The HD, DP and RMP values were 0.998 6, 0.994 2 and 0.005 8, respectively. The lowest genetic differentiation degree (Fst=0.006 89) was detected between Zhejiang She population and southern Han population. Principal component analysis (PCA) and median-joining network analysis showed that the genetic distance of Zhejiang She population with Guangxi Yao, Yunnan Dai and Southern Han populations was relatively close, but the population still had some unique genetic characteristics. Conclusion The whole mtDNA genomes are highly polymorphic in Zhejiang She population. The Zhejiang She population contains complex and diverse genetic components and has a relatively close maternal genetic relationship with Guangxi Yao, Yunnan Dai and Southern Han populations. Meanwhile, Zhejiang She population has kept its unique maternal genetic components.

Abstract
Objective: To explore the application effect and evaluation of virtual reality technology in oral implant therapy training. Methods: In November 2018, one adult patient (female, 36 years old) with missing right mandibular first molar was treated in the Department of Implantology, School and Hospital of Stomatology, Fujian Medical University. The three-dimensional virtual models of mandible and implant surgery tools were established, and the virtual reality software (Unity 3D 5.5.1) was imported. Combined with the virtual reality head mounted display, a virtual reality training system simulating the dental implant treatment process was independently developed. Ten refresher doctors and 20 graduate students in Department of Implantology, School and Hospital of Stomatology, Fujian Medical University from September 2018 to December 2019 were recruited as the experimental objects (no clinical experience was found). According to the level and seniority of doctors, they were randomly divided into virtual training group and conventional training control group, which made the two groups comparable, with 15 in each group. Subjective scores (including anatomical structure, surgical field of vision, cavity preparation, implant placement and process mastery) were given after the corresponding training in the two groups, and the virtual reality training system was used to test. The mesial and distal direction, buccolingual direction, depth and angle deviation of implants before and after the training were analyzed, and the differences between the two groups were compared. Results: The subjective scores of five dimensions in the virtual training group were significantly higher than those in the conventional training control group (P<0.05). In the virtual training group, the mesial and distal, buccolingual, depth and angle deviation of implants were (0.73±0.33), (0.78±0.41), (0.61±0.32) mm and 6.66°±3.87°. All of them were significantly lower than those in the control group [(0.85±0.32), (1.12±0.38), (0.89±0.24) mm and 9.68°±3.74°] (P<0.05). Conclusions: The self-developed virtual reality system of oral implant has good application effect, good operability and predictability. It can be effectively carried out in implant education and training, and it can strengthen skills of doctors, and is conducive to the practical operation.

Abstract
BACKGROUND Overweight and obesity in children and adolescents has become a worldwide epidemic. There are several studies that have concentrated on the prevalence rate of children and adolescents with intellectual disabilities (ID), whereas data on such a population on the mainland of China remain unclear. The purpose of this study was to investigate the prevalence rate of overweight and obesity among school-aged children and adolescents with ID on China's mainland. METHODS This study employed a cross-sectional design to examine the body weight status of 1873 children and adolescents (ages 6-18 years old) with ID in 35 special education schools. Body mass index was calculated, and the concepts of overweight and obesity were defined according to the standard of the Working Group for Obesity in China. RESULTS Data indicated that 18.2% (95% CI: 16.5%-20.0%) of children and adolescents with ID were overweight and 14.4% (95% CI: 12.8%-16.0%) were obese. Boys with ID were more likely to be overweight than girls with ID (OR = 1.48[95% CI: 1.13-1.94], P < 0.05). Children and adolescents with Down syndrome or autism spectrum disorder had a trend to be classified as overweight (OR = 1.76[95% CI: 1.22-2.54], P < 0.05; OR = 1.57[95% CI: 1.17-2.09], P < 0.05, respectively) or obesity (OR = 1.82[95% CI: 1.23-2.69], P < 0.05; OR = 1.40 [95% CI: 1.02-1.93], P < 0.05, respectively) compared with those with ID without these conditions. Moreover, children and teenagers with ID living in urban areas had a predisposition to be overweight (OR = 2.16[95% CI: 1.14-4.09], P < 0.05) or obese (OR = 3.25[95% CI: 1.41-7.50], P < 0.05) relative to those who lived in rural areas. CONCLUSION Results indicated that in China, the prevalence rate of overweight and obesity among school-aged children and adolescents with ID was remarkably high. Therefore, future research should make every effort to focus on reducing and preventing overweight and obesity of this population in China.

Abstract
Abstract Objective To assess the feasibility of the rbcL sequence of chloroplast DNA as a genetic marker to identify Cannabis sativa L. Methods The rbcL sequences in 62 Cannabis sativa L. samples, 10 Humulus lupulus samples and 10 Humulus scandens DNA samples were detected, and 96 rbcL sequences of the Cannabaceae family were downloaded from Genbank. Sequence alignment was performed by MEGA X software, the intraspecific and interspecific Kimura-2-Parameter (K2P) genetic distances were calculated, and the system clustering tree was constructed. Results The rbcL sequence length acquired by sequencing of Cannabis sativa L. and Humulus scandens were 617 bp and 649 bp, respectively, and two haplotypes of Cannabis sativa L. were observed in the samples. The BLAST similarity search results showed that the highest similarity between the sequences acquired by sequencing and Cannabis sativa L. rbcL sequences available from Genbank was 100%. The genetic distance analysis showed that the maximum intraspecific genetic distance (0.004 9) of Cannabis sativa L. was less than the minimum interspecific genetic distance (0.012 9). The results of median-joining network and system clustering tree analysis showed that Cannabis sativa L. and other members of the Cannabaceae family were located in different branches. Conclusion The rbcL sequence could be used as a DNA barcode for identifying Cannabis sativa L., and combined with comparative analysis of the rbcL sequence and system cluster analysis could be a reliable and effective detection method for Cannabis sativa L. identification in forensic investigation.

Abstract
Koumine (KM), the most abundant alkaloid in Gelsemium elegans, has anti-neuropathic, anti-inflammatory, and analgesic activities; thus, it has the potential to be developed as a broad-spectrum analgesic drug. However, factors determining the relationship between analgesic efficacy and the corresponding plasma KM concentration are largely unclear. The pharmacokinetics and pharmacodynamics of KM and their optimization in the context of neuropathic pain have not been reported. We investigated the pharmacokinetics and pharmacodynamics of KM after oral administration in a streptozotocin-induced rat model of diabetic neuropathic pain (DNP) using a population approach. A first-order absorption and elimination pharmacokinetics model best described the plasma KM concentration. This pharmacokinetic model was then linked to a linear pharmacodynamic model with an effect compartment based on the measurement of the mechanical withdrawal threshold. KM was rapidly absorbed (time to maximum plasma concentration: 0.14–0.36 h) with similar values in both DNP and naïve rats, suggesting that DNP did not influence the KM absorption rate. However, the area under the curve (AUC0–∞) of KM in DNP rats was over 3-fold higher than that in naïve rats. The systemic clearance rate and volume of KM distribution were significantly lower in DNP rats than in naïve rats. Blood glucose value prior to KM treatment was a significant covariate for the systemic clearance rate of KM and baseline value of the threshold. Our results suggest that streptozotocin-induced hyperglycemia is an independent factor for decreased KM elimination and its anti-allodynic effects in a DNP rat model. To the best of our knowledge, this is the first study to investigate the role of DNP in the pharmacokinetics and pharmacokinetics-pharmacodynamics of KM in streptozotocin-induced diabetic rats.

Abstract
Objective: To explore the influencing factors of job burnout of medical staff and provide reference for the formulation of intervention measures. Methods: From November to December, 2018, a questionnaire survey was conducted among medical staff in a general hospital by using the research design of the current situation survey. A total of 1193 questionnaires were distributed and 939 questionnaires were returned, with a recovery rate of 78.7%, including 891 valid questionnaires and an effective recovery rate of 94.9%. Social support rating scale (SSRs) was used to evaluate social support, and Maslach Burnout Scale (MBI-GS) was used to evaluate job burnout. Single factor analysis was performed by chi square test and Fisher exact probability method. To explore the influencing factors of job burnout by using disordered multi classification logistic. Results: The average age was (27.47 ± 4.22) years old, female accounted for 71.5% (637/891) . The total physical examination rate of job burnout was 46.6%. The scores of emotional exhaustion, cynicism and decreased sense of achievement were (10.10±3.75) , (6.14±3.43) , (17.91±4.13) respectively. Multiple logistic regression analysis showed that, compared with the non detected job burnout, the young, working for 1-3 years, average sleep ≤6 hours, and poor social support were more likely to have mild job burnout (OR=0.91, 0.40, 2.25, 2.38, P<0.05) ; female, high night shift frequency in the past year, average sleep ≤6 h. Those with poor social support were more likely to have moderate to severe job burnout (OR=1.59, 2.94, 4.01, 2.40, 3.66, P<0.05) . Conclusion: Corresponding measures should be taken to reduce job burnout and improve work efficiency.

Abstract
Objective: To explore the characteristics of executive function in children with attention-deficit/hyperactivity disorder comorbid with high functioning autism. Methods: A total of 165 children with attention-deficit/hyperactivity disorder (ADHD group), 65 children with attention-deficit/Hyperactivity disorder comorbid with high functioning autism (ADHD-HFA group), and 84 healthy controls (control group) (based on the criteria of DSM-5) were recruited from the Outpatient Clinic of Child Healthcare Department of Shen Zhen Children's Hospital. The Rey complex figure test (RCFT), trail making test (TMT), Stroop color-word test were used to assess working memory, shifting and inhibition. Results: ADHD group (2.1±1.9, 7±5, 2.1±2.0 and 7±5) and ADHD-HFA group (2.0±2.0, 7±6, 2.0±2.1 and 6±5) performed worse than control group (3.4±2.0, 10±5, 3.4±2.0 and 10±6) in Rey complex figure test (all P<0.05). ADHD group ((171±8) s, (27.40±0.82) s and (52.29±1.62) s) and ADHD-HFA group ((197±11) s, (29.7±1.1) s and (58.6±2.1) s) group took longer time on the TMT-2, Stroop2 and Stroop4 test than control group ((135±18) s, (22.4±1.9) s and (38.7±3.8) s) (all P<0.05). In children with low intelligence quotient (IQ), ADHD group ((30±8) s) and ADHD-HFA group ((34±9) s) performed worse on Stroop3 test than control group ((20±4) s) (all P<0.05). In children with average IQ, ADHD group ((19±5) s and (24±8) s) took longer time on the Stroop1 and Stroop3 test than control group ((16±3) s and (19±4) s) (all P<0.05). In children with high IQ, ADHD-HFA group ((20±8) s) spent more time on Stroop1 than control group ((15±4) s) (P<0.05). Inattention symptoms were associated with the time on TMT-2 of ADHD-HFA group (r=0.275 and 0.329, all P<0.05). The score of item 1 in autism spectrum screening questionnaire (ASSQ) was negatively correlated with immediate recall structure and detail scores as well as delay structure scores of Rey complex figure test (r=-0.358, -0.326 and -0.306, all P<0.05). The score of item 4 was positively correlated with errors of Stroop4 (r=0.296, P<0.05). The score of item 22 was positively correlated with time of color interference (r=0.279, P<0.05). Conclusions: Children with ADHD-HFA are likely to demonstrate the spatial working memory, shifting and inhibition deficits associated with ADHD alone. Some domains of executive function impairment in ADHD-HFA group are related with symptoms of inattention/hyperactivity and autism.

Abstract
Aging leads to changes in nearly all pharmacokinetic phases. Koumine (KM), an alkaloid derived from Gelsemium elegans Benth., is effective against age-associated chronic diseases, but its dose proportionality following oral administration in aged individuals remains unknown. Herein, we established and validated a simple method that requires low sample volumes to determine KM concentration in rats using ultra-performance liquid chromatography-tandem mass spectrometry. The maximum plasma concentration (Cmax) of 7 mg·kg−1 KM was ~12-fold and ~24-fold higher than that of 0.28 mg·kg−1 KM in adult and aged rats, respectively (P < 0.01). Time to reach Cmax (Tmax) for 7 mg·kg−1 KM was 4-fold longer in aged rats (P < 0.05). The area under the curve (AUC) of 7 mg·kg−1 KM was >17-fold and >43-fold higher than those of 0.28 mg·kg−1 KM in adult and aged rats, respectively (P < 0.01). The half-life (t1/2) of 7 mg·kg−1 KM was over 4-fold longer than that of 0.28 mg·kg−1 KM in adult rats (P < 0.01). The t1/2 of 1.4 and 7 mg·kg−1 KM were 1.5~2-fold longer, than that of 0.28 mg·kg−1 KM in aged rats (P < 0.05). The clearance rate of 7 mg·kg−1 KM was significantly lower in aged than in adult rats (P < 0.05). For 7.0 mg·kg−1 KM, the Cmax in aged rats was higher than in adult rats during the Tmax period (P < 0.05). In aged rats, the AUC for KM was >2.5-fold higher (P < 0.05) and the t1/2 was >60% longer than in adult rats (P < 0.05). These results help interpret the pharmacokinetics of KM in aging-associated diseases.

Abstract
Objective: To analyze the long-term efficacy and safety of thalidomide on refractory Crohn's disease (CD). Methods: A total of 79 patients with refractory CD in the First Affiliated Hospital of Sun Yat-sen University treated with thalidomide were enrolled in this retrospective study from September 2005 to July 2018. Clinical effects and adverse drug reactions were recorded and assessed. Results: In this cohort,69 patients were treated with thalidomide for ≥6 months. Sixty-eight patients among the 69 patients achieved complete clinical remission and were followed up for a median 33.5 months (range, 7-110 months). Seventeen cases relapsed during follow-up. The cumulative probabilities of remaining in remission at 12, 24, 60 months were 88.6% (95%CI 80.6%-96.6%), 80.7% (95%CI 70.3%-91.1%), 53.7% (95%CI 32.1%-75.3%) respectively. Disease activity was the only variable associated with relapse risk, with a hazard ratio (HR) of 3.559 for Crohn's disease activity index (CDAI) ≥220(95%CI 1.213-10.449, P<0.05). Adverse reactions were recorded in 42 (53.2%) patients including12 (15.2%) leading to discontinuation of thalidomide. No serious side effects were observed in all subjects. Conclusions: This study suggests a long-term benefit of maintenance treatment with thalidomide in refractory CD.Moderate to severe patients have an increased risk of relapse. The high incidence of drug adverse reactions may restrain the clinical application of thalidomide.

Abstract
CePd2Al2 crystallizes in the CaBe2Ge2-type tetragonal structure (P4/nmm, 129) and undergoes a phase transition to the orthorhombic Cmme structure at around 13 K. Its inelastic neutron spectra reveal an additional magnetic excitation that was ascribed to electron-phonon interaction leading to a formation of a new quantum quasi-bound vibron state. We present the first-principles calculations of the crystal field excitations and lattice dynamics calculations of the phonon dispersions to compare with the experimental data. The calculated crystal field energy splitting in CePd2Al2 agrees well with the model used to describe the experimental neutron scattering spectra. The first excited crystal field level moves to higher energies when undergoing the transformation from tetragonal to orthorhombic structure, in agreement with the experiment. The analysis based on calculated elastic constants and lattice dynamics calculations show that in both tetragonal and orthorhombic structures there are no imaginary modes for any q-wave vector within the Brillouin zone, and therefore the lattice structures are stable. The phonon dispersions and density of states are calculated for both crystal structures of CePd2Al2 and its nonmagnetic counterpart LaPd2Al2. The results generally agree well with the experimental data including the high phonon density of states around 12 meV. The phonon density of states is also used to calculate the mean squared displacement, Debye temperature, lattice heat capacity and compared with similar properties of the available experiment.

Abstract
Abstract
Currently, Aluminium (Al) alloys are increasingly used in the aerospace and automobile industries because of their outstanding properties such as lightweight and corrosion resistance properties. On the other hand, the applications of these materials are limited due to their poor formability especially at room temperature. Although hydroforming technology is one of the technique used to improve the formability of Al alloys, it still cannot fulfil the requirements of designers and manufacturers to form thin-walled complex shaped components. It has been found that high-speed forming is able to improve the formability of lightweight metals at room temperature. Thus, this investigation aims at investigating the effect of the novel technology called impact hydroforming (high-strain-rate forming) on the formability of Al alloys. Impact hydroforming (IHF) technology is proposed by combining the advantages of high-speed forming and hydroforming, and it was used to address the issues of quasi-static hydroforming. A high strain rate uniaxial tensile test was accomplished using Hopkinson tensile bar to investigate the effect of high strain rate on the formability of Al alloys. Thereafter, an IHF bulge experiment setup was developed by making use of a light gas gun which can accelerate the projectile up to 300m/s. The results show that the ductility and the formability of the Al alloy increased under high strain rate conditions, which means that the high-speed forming which is the basics of IHF technology is an appropriate method to improve the formability of Al alloys and form complex shape components.

Abstract
Aconitine (ACO), the main active component in Aconitum carmichaelii Debeaux (family: Ranunculaceae), has high cardiotoxicity, however the mechanisms of this effect remain unclear. Paeoniflorin (PF), the main chemical ingredient in herbaceous peony, can protect the heart from damage through antioxidant, vasodilatory and other effects. In this study, we focused on the mechanism by which PF reduces ACO cardiotoxicity. We selected H9c2 cells as the experimental model. MTT assay, Western blot analysis and real-time PCR were used to measure cell proliferation, apoptosis, ion channels and oxidative stress. Cell proliferation was significantly increased, the Bcl-2/Bax ratio and p53 level were upregulated, and Caspase-3 was slightly reduced in the ACO+PF group compared with the ACO group. SCN5A mRNA expression was significantly increased in the ACO+PF group compared with the ACO group, while RyR2 and Cx43 mRNA expression was decreased. Compared with the ACO group, the ACO+PF group showed marked decreases in extracellular lactate dehydrogenase (LDH) and intracellular malondialdehyde (MDA), while there was no difference in intracellular superoxide dismutase (SOD). The above data demonstrate that the cardiotoxicity of ACO in H9c2 cells was significantly decreased by PF.

Abstract
Objective: To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture. Methods: We collected social demographic, behavioral and serological information by means of the monitoring questionnaire and serological tests. Data was analyzed by using the chi-square test and logistic regression. Results: From April to June of 2010 to 2015, 14 092 cases of community population were selected as the study objects, with 267 cases diagnosed as HIV positive patients. The HIV positive rates were 3.24%, 3.07%, 1.17%, 1.38%,1.42% and 1.25%, respectively. We observed that when community population having the following characteristics as: living in Butuo country (OR=3.83), being males (OR=1.77), being Yi nationality (OR=4.40) being widowed (OR=28.57), with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92), or history of needle sharing among PWID (OR=8.53), were under higher risks for HIV infection. With histories as: having had secondary or above levels of schooling (OR=0.59), having protected sex with regular partners (OR=0.21) and with non-regular partners (OR=0.46), they seemed to be somehow protected for getting HIV infection. Conclusion: The positive HIV rates of HIV among community population in Dechang, Ningnan and Butuo varied from 0.10% to 8.77% while the HIV transmission among general population remained challenging.

Abstract
Objective: To understand the epidemiological and etiological characteristics of mumps in Fujian province, 2005-2017. Methods: All the reported mumps cases were collected through the National Notifiable Disease Information Management System, 2005-2017. Active search and interviews were conducted to collect the information on vaccination of mumps. Throat swab specimens were collected for cells culture, genotyping and gene sequence analysis on mumps virus (MuV). Results: A total of 83 959 cases of mumps were reported in Fujian province from 2005 to 2017, with an average annual incidence of 17.6 per 100 000. Since 2007, the incidence appeared increasing but then decreasing, reaching the lowest level (7.5 per 100 000), after the setup of a monitoring program. Annually, the onset time of mumps showed an obvious two seasonal peaks, one from April to July, with a weakening trend, and the other from October to January with a rising trend. Most of the mumps cases occurred among students, kindergarten and scattered children (89.2%, 5 814/6 517), children aged 5-9 years (38.8%, 2 527/6 517), with cases reported from every region. Program from the pathogen surveillance showed that the transmission chain of G genotype mumps virus did exist in Fujian. Data from the sequence analysis revealed that mutations in the nucleotide of G genotype strain in 2015 had led to mutation of 6 amino acid sites in the SH gene coding region, resulting in the differences appearing in both nucleotide and amino acid homology with type A vaccine strain. Conclusions: The incidence of mumps decreased annually, in Fujian. Prevention programs should focus on primary and secondary school students. In Fujian province, we also noticed the transmission chain of mumps G genotype with some amino acid mutations in the SH gene coding region. Monitor programs on both epidemiologic and etiology, should be strengthened.

Abstract
MiR-222-3р has been implicated in tumor cell proliferation and has an important role in the differentiation and maturation of myogenic cells. However, its role in skeletal myoblast proliferation is still unclear. In this study, we found that miR-222-3р expression increases initially and then decreases during C2C12 myoblast proliferation. Using synthetic miRNA mimics and inhibitors in gain- or loss-of-function experiments, we snowed that miR-222-3р overexpression in C2C12 cells promotes myoblast proliferation and represses myofiber formation, while miR-222-3р downregulation has the opposite effect. Using a prediction program, BTG2 was identified as a possible target gene of miR-222-3р. During myogenesis, miR-222-3р mimics repress BTG2 expression, while miR-222-3р inhibitors promote BTG2 expression. Using dual-luciferase reporter assay, we further demonstrated that miR-222-3р specifically targets BTG2. Additionally, we show that siRNA-mediated downregulation of BTG2 expression in C2C12 myoblasts promotes the proliferation and suppresses differentiation. In conclusion, we provide a novel insight into the mechanism by which miR-222-3р regulates the proliferation and differentiation of C2C12 myoblasts by targeting BTG2. This information contributes to our understanding of the role of miRNAs in skeletal muscle development.

Abstract
Genetic markers in forensic DNA typing experienced the variable number of tandem repeats (VNTR) sequences and the short tandem repeats (STR) sequences. With the emerge of sequencing technology, the third generation of genetic markers were found out, which usually have two alleles including single nucleotide polymorphism (SNP) and insertion/deletion (InDel), also known as biallelic genetic markers. Because of the insertions or deletions of DNA fragments, InDel genetic marker reveals DNA fragment length polymorphism and widely distributes across the whole genome. InDel genetic marker is numerous and has the characteristics of STR and SNP genetic markers, which has been applied in the fields of genetics and anthropology. This review focuses on the research progress of InDel genetic marker in forensic science, aiming to review and summarize the main research findings in recent years and provide clues for future researches.

Abstract
BACKGROUND Anti-melanoma differentiation-associated gene 5 (MDA5) dermatomyositis (DM) is a distinctive subtype of DM that carries a significant risk of interstitial lung disease (ILD). The mechanisms remain elusive. OBJECTIVES To explore the role of the type I interferon (IFN) system in the pathogenesis of anti-MDA5 DM. METHODS Twenty patients with anti-MDA5 DM were studied and compared with patients with anti-aminoacyl-tRNA synthetase (ARS) DM (n = 10) and autoantibody-negative patients with DM (n = 20). The levels of inflammatory cytokines, B-cell-activating factor (BAFF) and Krebs von den Lungen (KL)-6 in blood were tested by enzyme-linked immunosorbent assay and multiplex assays. Expressions of transcripts for IFN-associated sensors and type I IFN-inducible genes in peripheral blood mononuclear cells (PBMCs) were detected by real-time polymerase chain reaction. Expressions of the signal transducer and activator of transcription (STAT)1, interferon-stimulated gene (ISG)15 and MxA proteins in skin lesions were analysed by immunohistochemistry. RESULTS Plasma IFN-α levels were significantly increased in patients with anti-MDA5 DM. PBMCs from patients with anti-MDA5 DM showed significant upregulation of the TLR3, TLR7, IFIH1 and DDX58 genes, as well as serial IFN-inducible genes. Skin biopsies from patients with anti-MDA5 DM were characterized by strong expression of the STAT1, ISG15 and MxA proteins. In the patients with anti-MDA5 DM and ILD with high IFN-α production, there was a positive quantitative correlation between IFN-α and BAFF (rs = 0·63, P = 0·044). In addition, the higher levels of BAFF paralleled the higher concentrations of KL-6 (rs = 0·86, P = 0·0012). CONCLUSIONS Our data confirm the aberrant activation of the type I IFN system in anti-MDA5 DM. Overproduction of IFN-α linked with BAFF may be implicated in the development of ILD.

Abstract
The classification of miscible and immiscible systems of binary alloys plays a critical role in the design of multicomponent alloys. By mining data from hundreds of experimental phase diagrams, and thousands of thermodynamic data sets from experiments and high-throughput first-principles (HTFP) calculations, we have obtained a comprehensive classification of alloying behavior for 813 binary alloy systems consisting of transition and lanthanide metals. Among several physics-based descriptors, the slightly modified Pettifor chemical scale provides a unique two-dimensional map that divides the miscible and immiscible systems into distinctly clustered regions. Based on an artificial neural network algorithm and elemental similarity, the miscibility of the unknown systems is further predicted and a complete miscibility map is thus obtained. Impressively, the classification by the miscibility map yields a robust validation on the capability of the well-known Miedema’s theory (95% agreement) and shows good agreement with the HTFP method (90% agreement). Our results demonstrate that a state-of-the-art physics-guided data mining can provide an efficient pathway for knowledge discovery in the next generation of materials design.

Abstract
Obiective: To explorethe correlation between Neo-Bioscore and disease-free survival (DFS) after neoadjuvant therapy in patients with breast cancer in China. Methods: The clinical and pathological data of 429 patients with early or locally advanced breast cancer who received neoadjuvant therapy at the No.307 Hospital of PLA from January 1, 2005 to December 31, 2015 were analyzed and we followed up their DFS. Results: Neo-Bioscore were closely related to DFS (χ(2)=47.662, P<0.001). When the groups were divided by Neo-Bioscore 3, they weremore relevantto DFS (HR=5.093 vs HR=2.044), equivalent tothe role of traditional recurrence risk grouping in guiding the choice of adjuvantendocrine regimen for hormone receptor (HR) positive patients who were premenopausalafter neoadjuvant chemotherapy, andmore relevantto DFS than whetherthe pathologic complete response (pCR)grouping in the same molecular pathology subgroup of HR positive/human epidermal growth factor receptor 2 (HER-2)negative (P<0.001 vs P=0.166), HER-2 positive (P<0.001 vs P=0.166), HRnegative/HER-2 negative (P<0.001 vs P=0.166). Conclusions: Neo-Bioscore could be used as an early indicator of predicting DFS for breast cancer patients after neoadjuvant therapy.When the groups were divided by Neo-Bioscore 3, they were more relevant to DFS, equivalent to the role of traditional recurrence risk grouping in guiding the choice of adjuvantendocrine regimen for premenopausal HR positive patients, andmore relevantto DFS than whetherthe pCRgrouping in the same molecular pathology subgroup.

Abstract
Malignant tumor is the most heterogeneous human disease, and it has been gradually reached the consensus in clinical oncology that the personalized treatment of tumor patients should be directed by molecular diagnostics. However, the ever-changing characteristic of tumor in heterogeneity and the fact that tissue samples are usually unavailable highlight the function and significant of liquid biopsy. The material that could be used in liquid biopsy are mainly the circulating tumor DNA, circulating tumor cells and extracellular vesicles, which though have their own advantages and disadvantages, but could complement to each other, thus accurately and comprehensively reflecting the characteristic of the tumor and gave the best direction for patient's individualized therapy. This article reviewed the recent advances of liquid biopsy and explained its importance in tumor precision medicine.

Abstract
A retrospective case control study was conducted in the Peking Union Medical College Hospital. Medical records were reviewed for demographic data, clinical features, laboratory results, systemic lupus erythematosus (SLE) disease activity evaluations, and ophthalmic examinations to investigate the clinical characteristics and significance of retinal vasculopathy (RV) in Chinese patients with systemic lupus erythematosus. The prevalence of RV was approximately 0.66% (35/5298) in SLE patients. A total of 60 eyes were involved. The ocular presentations included decrease of visual acuity (48/60, 80%), visual field loss (7/60, 11.7%), and diplopia (3/60, 5%). Ophthalmic fundoscopic examination revealed cotton-wool spots (30/60, 50%), retinal vascular attenuation (31/60, 51.6%), and hemorrhages (41/60, 68.3%). Retinal angiogram showed that 72.7% (16/22) eyes had vaso-occlusion. The ophthalmic episodes could occur at any stage of SLE duration, with a median of 12 months (0-168 months) following SLE onset. Twenty-one (35%) eyes did not recover, or even worsened, during hospital stay. RV was found to be significantly associated with neuropsychiatric lesions (51.4% vs. 21.3%, p = .005) and hematological disturbance (62.9% vs. 34.3%, p = .005). SLE patients with RV had significantly higher SLE disease activity index scores than controls (19.9 ± 0.9 vs. 10.2 ± 0.7, p < .001). An inverse association of anti-SSA antibody with RV was detected (34.3% vs. 67.1%, p = .001). Nervous system disturbance (odds ratio (OR) = 4.340, 95% confidence interval (CI) 1.438, 13.094, p = .009) and leukocytopenia (OR = 6.385, 95% CI 1.916, 21.278, p = .003) were independent risk factors, while anti-SSA antibody positivity (OR = 0.249, 95% CI 0.087, 0.710, p = .009) was a protective factor for RV in SLE patients. In certain cases, RV is a threatening condition for SLE patients presenting with clinical ocular manifestations. Ophthalmo-fundoscopic detection is recommended as soon as SLE is diagnosed.

Abstract
Recent studies found that peripapillary microcirculation was damaged in glaucoma patients, indicating that blood flow in the optic nerve head is important in the pathogenesis of glaucoma. Effects of different antiglaucoma drugs on optic papilla blood flow deserve attention. Prostaglandins is the first line antiglaucoma drug. The experimental and clinical studies on the potential of prostaglandins to modify the blood flow in the optic papilla and related mechanisms are reviewed in this article. Effects of ocular blood flow increase on the treatment of glaucoma require further investigations. (Chin J Ophthalmol, 2017, 53: 73-76).

Abstract
Glaucoma is a leading cause of irreversible blindness world widely. The pathogenesis of glaucoma is still not fully understood. It is proposed that the microcirculation of optic nerve head (ONH) may play an important role in glaucomatous optic neuropathy, but the hypothesis is still lack of direct evidence. In this review, we summarized the technical developments in ONH blood flow examination and findings on relationship between decreased ONH microcirculation and glaucoma. These evidences implicate that damaged ONH microcirculation involves in pathogenesis of glaucoma. (Chin J Ophthalmol, 2016, 52: 466-470).

Abstract
Objective: To analyze the predict values of pathologic complete response (pCR) rates for patient outcome according to breast cancer (BC) molecular subtypes. Methods: Four hundred and sixteen patients with confirmed BC who received neoadjuvant chemotherapy (NCT) in The Affiliated Hospital of Military Medical Science Academy of the PLA were enrolled.The clinical and pathological characteristics of patients were collected. The primary endpoint was pCR rate and the secondary endpoint was disease free survival (DFS). We analyzed the predict values of pCR rate for patient outcome, and the predict factors for DFS by univariate and multivariate Analysis. Results: A total of 416 BC patients confirmed by pathology were enrolled and received treatment and assessment in this study. The overall pCR rate was 23.1% (96/416). The pCR rate was 6.9% (14/204) in patients of HR+ /HER2- Subtype, 41.5% (27/65) in HR-/HER2+ Subtype, 30.9% (17/55) in HR+ /HER2+ Subtype, and 41.1% (37/91) in HR-/HER2- Subtype. The correlation of the pathological status and the patient outcome was analyzed in all patients. Compared with no pCR group, pCR group had significant higher DFS rates. In HER2+ Subtype and HR-/HER2- Subtype, DFS rates of patients who achieved pCR was higher than that of who didn't achieved pCR. In HR+ /HER2- Subtype, DFS rates of patients who achieved pCR was higher than that of who didn't achievced pCR, but without statistics difference. The Cox proportional hazards regression analysis revealed that ER status, T stage, pCR affected the patient outcome of BC. Conclusion: So far, pCR was an established prognostic factor: reaching a pCR could predicte improved survival in HER2-enriched BC and triple-negative breast cancer (TNBC) subgroup, while data remain controversial for the luminal subtypes. Our results do not support the use of pCR as a surrogate end point of treatment efficacy in unselected patients with BC submitted to neoadjuvant systemic therapy.

Abstract
The profound effects of reactive elements (REs) on the adhesion energy and adhesive strength of the α-Al2O3/β-NiAl interface in thermal barrier coating (TBC) systems have attracted increasing attention because RE-doping has played a significant role in improving the thermal cycling lifetime of TBCs. However, the fundamental mechanism is, so far, not well understood due to the experimental difficulty and theoretical complexity in interface modelling. For this purpose, in the present study we have performed comprehensive density functional theory calculations and information targeted experiments to underline the origin of the surprising enhancement of interface adhesion, stability and mechanical strength of the α-Al2O3/β-NiAl interface by different RE doping levels. Our results suggest that the interface failure firstly appears within the NiAl layer adjacent to the Al-terminated oxide under mechanical loading, while the formation of O-RE-Ni bond pairs at the interface can effectively hinder the interface de-cohesion, providing a higher mechanical strength. By comparing several typical REs, it is observed that Hf can emerge not only with the highest interface adhesion energy, but also the highest mechanical strength; in agreement with our experimental results. By continuously increasing the dopant concentration, the strengthening effect may increase correspondingly, but is limited by the solute solubility. These results shed light into the effect of REs on the stability and strength of the α-Al2O3/β-NiAl interface, providing theoretical guidance for interface design via a combinational analysis of bond topology and electronic structure.

Abstract
The rapid development of second generation sequencing (SGS) within the past few years has led to the increasement of data throughput and read length while at the same time brought down substantially the sequencing cost. This made new breakthrough in the area of biology and ushered the forensic genetics into a new era. Based on the history of sequencing application in forensic genetics, this paper reviews the importance of sequencing technologies for genetic marker detection. The application status and potential of SGS in forensic genetics are discussed based on the already explored SGS platforms of Roche, Illumina and Life Technologies. With these platforms, DNA markers (SNP, STR), RNA markers (mRNA, microRNA) and whole mtDNA can be sequenced. However, development and validation of application kits, maturation of analysis software, connection to the existing databases and the possible ethical issues occurred with big data will be the key factors that determine whether this technology can substitute or supplement PCR-CE, the mature technology, and be widely used for cases detection.

As a novel approach for disease control and prevention, nutritional modulation of the intestinal health has been proved. However, It is still unknown whether branched-chain amino acid (BCAA) is needed to maintain intestinal immune-related function. The objective of this study was to determine whether BCAA supplementation in protein restricted diet affects growth performance, intestinal barrier function and modulates post-weaning gut disorders. One hundred and eight weaned piglets (7.96±0.26 kg) were randomly fed one of the three diets including a control diet (21% crude protein [CP], CON), a protein restricted diet (17% CP, PR) and a BCAA diet (BCAA supplementation in the PR diet) for 14 d. The growth performance, plasma amino acid concentrations, small intestinal morphology and intestinal immunoglobulins were tested. First, average daily gain (ADG) (p<0.05) and average daily feed intake (ADFI) (p<0.05) of weaned pigs in PR group were lower, while gain:feed ratio was lower than the CON group (p<0.05). Compared with PR group, BCAA group improved ADG (p<0.05), ADFI (p<0.05) and feed:gain ratio (p<0.05) of piglets. The growth performance data between CON and BCAA groups was not different (p>0.05). The PR and BCAA treatments had a higher (p<0.05) plasma concentration of methionine and threonine than the CON treatment. The level of some essential and functional amino acids (such as arginine, phenylalanine, histidine, glutamine etc.) in plasma of the PR group was lower (p<0.05) than that of the CON group. Compared with CON group, BCAA supplementation significantly increased BCAA concentrations (p<0.01) and decreased urea concentration (p<0.01) in pig plasma indicating that the efficiency of dietary nitrogen utilization was increased. Compared with CON group, the small intestine of piglets fed PR diet showed villous atrophy, increasing of intra-epithelial lymphocytes (IELs) number (p<0.05) and declining of the immunoglobulin concentration, including jejunal immunoglobulin A (IgA) (p = 0.04), secreted IgA (sIgA) (p = 0.03) and immunoglobulin M (p = 0.08), and ileal IgA (p = 0.01) and immunoglobulin G (p = 0.08). The BCAA supplementation increased villous height in the duodenum (p<0.01), reversed the trend of an increasing IELs number. Notably, BCAA supplementation increased levels of jejunal and ileal immunoglobulin mentioned above. In conclusion, BCAA supplementation to protein restricted diet improved intestinal immune defense function by protecting villous morphology and by increasing levels of intestinal immunoglobulins in weaned piglets. Our finding has the important implication that BCAA may be used to reduce the negative effects of a protein restricted diet on growth performance and intestinal immunity in weaned piglets.

Abstract
The myosin heavy chain (MyHC) composition, glycolytic potential, mitochondrial content, and gene expression related to energy metabolism were analyzed in eight muscles from Tibetan pigs, to study how meat quality develops in different muscle tissues. The muscles were classified into three clusters, based on MyHC composition: masseter, trapezius, and latissimus dorsi as 'slow-oxidative-type'; psoas major and semimembranosus as 'intermediate-type'; and longissimus dorsi, obliquus externus abdominis, and semitendinosus as 'fast-glycolytic-type'. The 'slow-oxidative-type' muscles had the highest MyHC I and MyHC IIA content (P < 0.01); 'intermediate-type' muscles, the highest MyHC IIx content (P < 0.01); and 'fast-glycolytic-type' muscles, the highest MyHC IIb content (P < 0.01). The pH values measured in 'slow-oxidative-type' muscles were higher than those in the other clusters were; however, the color of 'fast-glycolytic-type' muscles was palest (P < 0.01). Mitochondrial content increased in the order: fast-glycolytic-type < intermediate-type < slow-oxidative-type. In the 'slow-oxidative-type' muscles, the expression levels of genes related to ATP synthesis were higher, but were lower for those related to glycogen synthesis and glycolysis. Mitochondrial content was significantly positively correlated with MyHC I content, but negatively correlated with MyHC IIb content. MyHC I and mitochondrial content were both negatively correlated with glycolytic potential. Overall, muscles used frequently in exercise had a higher proportion of type I fibers. 'Slow-oxidative-type' muscles, rich in type I fibers with higher mitochondrial and lower glycogen and glucose contents, had a higher ATP synthesis efficiency and lower glycolytic capacity, which contributed to their superior meat quality.
