Abstract
In recent years, the growing incidence of health issues among Chinese students, including obesity, diabetes, and other chronic diseases, has been attributed to a sedentary lifestyle, lack of physical activity, and unhealthy eating habits. Physical education (PE) classes play a crucial role in promoting physical activity and fostering healthy lifestyles among Chinese students. The purpose of this study was to investigate the influence of the healthy PE curriculum model on the sports ability of senior high school students in China. The trial adopted a quasi-experimental design with equivalent groups. The experimental group followed the healthy PE curriculum model in their PE classes, while the control group received traditional technical instruction. During the 12-week intervention, 149 senior high school students completed the sports ability test as both the pre-test and post-test measurements for this experimental study. The results indicated that the experimental group showed significant improvements in sports ability compared to the control group, highlighting the positive effects of the healthy PE curriculum model. The structural characteristics of the healthy PE curriculum model provided essential support for students' learning and proved to be an effective way to promote physical literacy among senior high school students in China.

Abstract
Objective: To compare the outcomes between the patients of peroneal tendon dislocation treated by either total endoscopic surgery with preferential incision of the tendon sheath or traditional open surgery. Methods: This is a retrospective cohort study. The clinical data of 45 patients with peroneal tendon dislocation were operated on Department of Sports Medicine and Joint Surgery, Nanjing First Hospital from July 2016 to June 2020. There were 26 males and 19 females,aged (31.2±9.3) years (range: 17 to 45 years). Among them,23 patients underwent open peroneal tendon groove deepening followed by tendon sheath repair(traditional open group), and the other 22 patients underwent similar operations but all-endoscopically with preferential incision of peroneal tendon sheath(total endoscopic group). The perioperative data of patients were collected, and pain visual analogue score (VAS) was used to evaluate the pain changes before and after surgery and during the follow-up period, and the American Orthopaedic Foot and Ankle Society anklehindfoot scale (AOFAS-AH), range of motion (ROM), the MOS item short form health survey (SF)-36, and the homemade questionnaire of patient satisfaction were used to evaluate the patients' outcomes after the operation, and CT scan was carried out to observe the deepening of the fibular groove and MRI to observe the status of the peroneal tendon and sheath during the follow-up. Independent sample t test, Wilcoxon rank sum test and repeated measure ANOVA were used for comparison of quantitative data between groups. Chi-square test,Mann-whitney U or Fisher exact test was used for comparison of classified data, respectively;and paired sample t test was used for comparison of quantitative data before and after surgery in groups. Results: There was no statistically significant difference between the two groups of patients in terms of gender, age, disease duration, side of injury, and injury typing (all P>0.05). There was no significant difference between the two groups in terms of operation time((47.9±5.4)minutes vs. (47.2±6.3)minutes;t=0.402, P=0.690), but the incision length ((2.17±0.35)cm vs. 5.97±0.42)cm;t=32.892,P<0.01)and hospitalization time ((4.0±1.7)days vs. (7.6±3.6)days;t=4.249,P<0.01) were significantly shorter in the total endoscopic group than those in the traditional open group. All patients were followed up for more than 12 months, and the follow-up time was (19.2±3.9) months (range: 12 to 24 months). The total endoscopic group showed a significant increase in VAS, AOFAS scores, SF-36 scores and patient satisfaction rate at 3 months postoperatively and the last follow-up (all P<0.05). Three months after surgery, the ROM in the total endoscope group was higher than that in the traditional group ((62.14±1.46) ° vs. (53.13±1.52) °;t=20.315, P<0.01), and there was no significant difference between the two groups at the last follow-up ((63.18±1.10) ° vs. (63.48±2.43) °;t=0.531, P=0.599). Conclusion: Total endoscopic surgery with preferential incision of the tendon sheath has the advantages of minimally invasivenessas compared with traditional open surgery with faster recovery and better outcome.

Abstract
The rapid development of technology has ushered in a new era of minimally invasive and intelligent surgery.Minimally invasive surgeries, such as small incision, percutaneous surgery, arthroscopic surgery, and endoscopic surgery, have contributed to less invasive surgical trauma, better cosmesis, and faster recovery. Furthermore, the recent adoption of artificial intelligence (AI) has introduced new assistances and tools for minimally invasive foot and ankle surgery. By the help of advanced AI algorithms, surgeons can accurately make diagnose and personalized treatment strategies. The application of computer-assisted navigation systems and robotics has facilitated precise surgical procedures and real-time confirmation of surgical outcomes. Foot and ankle surgery has lagged behind other surgical specialties in adopting these advancements. Currently, the integration of various forms of minimally invasive surgery and AI technology stands as the main trend in the development of foot and ankle surgery. It is believed that in the near future, intelligent minimally invasive surgery will become the mainstream in the domain of foot and ankle.

Abstract
The high incidence of adolescent depression has become the focus of social and academic attention. Exercise is an important method to improve adolescent depression, but its intervention effect is still controversial. This study first compares and analyzes the relevant studies at home and abroad and finds that exercise prescription in adolescent depression intervention is not accurate enough. A meta-analysis was conducted to develop a precise exercise intervention strategy for adolescent depression. Firstly, this thesis identified how to optimize five elements (exercise intensity, exercise frequency, exercise time, exercise cycle, and exercise type) of exercise prescription to improve depression in adolescents. This is the problem. Furthermore, the concept of "precision exercise" was proposed, and a precision exercise intervention strategy (moderate-intensity aerobic exercise for 8-10 weeks, 3 times/week, 45-50 min/time) was constructed to improve adolescent depression. This paper also presents research that strengthens the cross-sectional research and empirical research on adolescent depression and establishes a precision exercise prescription database for adolescent depression in China. In conclusion, this study not only puts forward the concept of "precision exercise" but also constructs a precision exercise intervention strategy for adolescent depression, which has important theoretical and practical significance for improving the high incidence of adolescent depression.

Abstract
Purpose This study aimed to explore the effects of additional visual tasks in physical exercise on the vision and balance ability of children, and to verify whether children's vision mediated the influence of physical exercise on their balance ability. Methods The study randomly selected 86 students aged 9-10 years old from a school in Suzhou city, dividing them into an experimental group (n = 43) and a control group (n = 43). The experimental group participated in physical exercise with additional visual tasks, while the control group engaged in routine physical exercise. The experiment lasted for 16 weeks, with kinetic visual acuity (KVA), uncorrected distance visual acuity (UDVA), static balance, and dynamic balance measured before and after the experiment. Results The results showed that after the experiment, the experimental group had significantly improved kinetic visual acuity (KVA), uncorrected distance visual acuity (UDVA), static balance, and dynamic balance. In contrast, the control group had significantly decreased kinetic visual acuity, no significant improvement in uncorrected distance visual acuity, and no significant difference in dynamic balance and static balance. In the experimental group, there was a moderate positive correlation between kinetic visual acuity and uncorrected distance visual acuity, and a moderate positive correlation between uncorrected distance visual acuity and both static and dynamic balance. The study also found that uncorrected distance visual acuity partially mediated the effect of additional visual tasks during physical exercise on static and dynamic balance among children. Conclusion In conclusion, adding visual tasks to physical exercise had a positive effect on improving children's vision and balance ability. Kinetic visual acuity and uncorrected distance visual acuity were positively correlated, and uncorrected distance visual acuity was positively correlated with both static and dynamic balance. Uncorrected distance visual acuity partially mediated the effect of physical exercise on children's balance ability.

Abstract
Microplastics are emerging pollutants that threaten soil health and food safety. Recently, there has been increasing interest in understanding the behavior of these particles in the rhizosphere, specifically regarding the potential uptake of microplastics into crops. Arbuscular mycorrhizal (AM) fungi are widespread soil fungi, forming symbiotic associations with most terrestrial plants. Therefore, it is essential to investigate if AM fungi could protect crops from microplastics in soil. Here, we grew vegetables (Lactuca sativa) inoculated with/without the AM fungus Rhizophagus irregularis at various levels of poly(methyl methacrylate) (PMMA) soil pollution (0, 0.05, 0.1, 0.2, and 0.4%, mass ratio of the pollutant to soil). Our findings revealed that the proportion of transport of PMMA from roots to shoots decreased significantly in mycorrhizal crops. This reduction occurred because some PMMA particles were immobilized by AM vesicles and intraradical fungal hyphae. However, AM symbiosis did not substantially reduce the uptake of microplastics by crops from soil. Mycorrhizal fungi might enhance the resistance of crops to microplastics through transforming the chemical properties of microplastics, reducing their complexation to crop components, and promoting crop phosphorus nutrition at high microplastic addition levels. Our study is the first report to achieve rapid quantification of microplastics in mycorrhizal crops using microscale combustion calorimetry, demonstrating that AM fungi have the ability to immobilize microplastics. The study allows a deeper insight into microplastic behavior in AM-associated crops and supports the potential application of AM fungi in crop cultivation under microplastic contamination.

Abstract
Objective: To describe the current status and trends in the treatment of patent ductus arteriosus (PDA) among very preterm infants (VPI) admitted to the neonatal intensive care units (NICU) of the Chinese Neonatal Network (CHNN) from 2019 to 2021, and to compare the differences in PDA treatment among these units. Methods: This was a cross-sectional study based on the CHNN VPI cohort, all of 22 525 VPI (gestational age<32 weeks) admitted to 79 tertiary NICU within 3 days of age from 2019 to 2021 were included. The overall PDA treatment rates were calculated, as well as the rates of infants with different gestational ages (≤26, 27-28, 29-31 weeks), and pharmacological and surgical treatments were described. PDA was defined as those diagnosed by echocardiography during hospitalization. The PDA treatment rate was defined as the number of VPI who had received medication treatment and (or) surgical ligation of PDA divided by the number of all VPI. Logistic regression was used to investigate the changes in PDA treatment rates over the 3 years and the differences between gestational age groups. A multivariate Logistic regression model was constructed to compute the standardized ratio (SR) of PDA treatment across different units, to compare the rates after adjusting for population characteristics. Results: A total of 22 525 VPI were included in the study, with a gestational age of 30.0 (28.6, 31.0) weeks and birth weight of 1 310 (1 100, 1 540) g; 56.0% (12 615) of them were male. PDA was diagnosed by echocardiography in 49.7% (11 186/22 525) of all VPI, and the overall PDA treatment rate was 16.8% (3 795/22 525). Of 3 762 VPI who received medication treatment, the main first-line medication used was ibuprofen (93.4% (3 515/3 762)) and the postnatal day of first medication treatment was 6 (4, 10) days of age; 59.3% (2 231/3 762) of the VPI had been weaned from invasive respiratory support during the first medication treatment, and 82.2% (3 092/3 762) of the infants received only one course of medication treatment. A total of 143 VPI underwent surgery, which was conducted on 32 (22, 46) days of age. Over the 3 years from 2019 to 2021, there was no significant change in the PDA treatment rate in these VPI (P=0.650). The PDA treatment rate decreased with increasing gestational age (P<0.001). The PDA treatment rates for VPI with gestational age ≤26, 27-28, and 29-31 weeks were 39.6% (688/1 737), 25.9% (1 319/5 098), and 11.4% (1 788/15 690), respectively. There were 61 units having a total number of VPI≥100 cases, and their rates of PDA treatment were 0 (0/116)-47.4% (376/793). After adjusting for population characteristics, the range of standardized ratios for PDA treatment in the 61 units was 0 (95%CI 0-0.3) to 3.4 (95%CI 3.1-3.8). Conclusions: From 2019 to 2021, compared to the peers in developed countries, VPI in CHNN NICU had a different PDA treatment rate; specifically, the VPI with small birth gestational age had a lower treatment rate, while the VPI with large birth gestational age had a higher rate. There are significant differences in PDA treatment rates among different units.

Abstract
PURPOSE/OBJECTIVE(S) Bone marrow sparing intensity modulated radiotherapy (BMS-IMRT) can reduce the incidence of acute hematologic toxicity (HT) for locoregionally advanced cervical cancer (LACC) patients receiving concurrent chemoradiotherapy (CCRT), but the norm has been controversial. The purpose of the study was to evaluate the effects of bone marrow (BM) V40 <25% on decreasing the incidence of acute HT in a prospective clinical trial. MATERIALS/METHODS A total of 242 LACC patients were recruited from May 2021 to May 2022, who were evenly randomized into BMS-IMRT group and standard IMRT group according to a computer-generated random number list. All patients received pelvic irradiation with concurrent cisplatin (40 mg/m2 weekly), followed by brachytherapy. For patients in BMS-IMRT group, the outer contour of pelvic bone, lumbar spine and left and right femur heads were additionally delineated as a surrogate for BM, and V40 <25% was prescribed. Blood counts were tested weekly, of which nadirs during external beam radiotherapy (EBRT) were graded to assess acute HT as primary observation index. Second observation index were dosimetric parameters of EBRT plan from the dose volume histograms (DVHs). Binary logistic regression model and receiver operating characteristic (ROC) curve were used for predictive value analysis. RESULTS Baseline demographic, disease and treatment characteristics were all balanced between BMS-IMRT group and standard IMRT group. BMS-IMRT was associated with a lower incidence of grade ≥2 and grade ≥3 acute HT, leukopenia and neutropenia (72.70% vs 90.90%, P <0.001*; 16.50% vs 65.30%, P <0.001*; 66.10% vs 85.10%, P = 0.001*; 13.20% vs 54.50%, P <0.001*; 37.20% vs 66.10%, P <0.001*; 10.70% vs 43.80%, P <0.001*). Plan target volume (PTV) for all patients satisfied the clinical requirement of V(100%) ≥95%, and conformity and homogeneity were both comparable between 2 groups. BMS also decreased dose delivered to the organs at risk (OARs) including rectum, bladder and left and right femur head. Univariate and multivariate analyses showed that BM V40 was an independent risk factor for grade ≥3 acute HT (odds ratio [OR] = 2.734, 95% confidence interval [CI] = 1.959-3.815, P <0.001*). Cutoff value was 25.036% and area under the curve (AUC) was 0.786. The nomogram was constructed, which was rigorously evaluated and internally cross-validated, showing good predictive performance. CONCLUSION BM V40 <25% can reduce the risks of acute HT for LACC patients receiving CCRT while the dose delivery of target volume and other normal tissues were not compromised. With great practicality and applicability, BM V40 <25% is a promising strategy, making BMS-IMRT widespread especially in the area where application of image guided radiotherapy (IGRT) such as 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET)/CT is not popularized.

Abstract
PURPOSE/OBJECTIVE(S) To compare dose distributions created by using two Inverse Planning Simulated Annealing (IPSA) and Hybrid Inverse Planning Optimization (HIPO) in three-dimensional (with CT image guidance) brachytherapy planning for cervical cancer. MATERIALS/METHODS Brachytherapy plans for thirty patients with cervical cancer were created using the IPSA and HIPO algorithms (The IPSA algorithm is calculated based on the anatomical structure, and the simulated annealing algorithm is used to optimize the residence time, and the HIPO algorithm is the optimization and replacement for the IPSA). To obtain a HIPO plan, a manually optimized post-loading treatment plan was applied to these 30 patients, and then the treatment plan was reoptimized using the HIPO algorithm based on the original image information. Individual patients will consider interpolation therapy according to the needs of their condition. The types of plans were compared based on a variety of dose volume parameters, including the mean dose covering 90% of high-risk clinical target volume (D90 for HR-CTV), the mean dose to 2 cm3 volume (D2cc) for bladder, rectum, intestine and sigmoid, and average treatment time were compared and analyzed. RESULTS Compared with the two groups of plans, mean value of HR-CTV D90 for the HIPO plans was (585 cGy), which was significantly higher than that for the IPSA plans (567 cGy. This difference is statistically significant (P<0.05). The HIPO plans had mean D2cc 422±47 cGy for bladder, 403±38 cGy for rectum, which were lower than those from the SA plans, i.e., 446±42 cGy for bladder and 427±31 cGy for rectum; These differences were statistically significant (t = 5.125, 4.729, P <0.05). There was no statistically significant difference in the sigmoid D2cc doses between the two algorithms. The treatment times for delivering the two types of plans were not significant different. CONCLUSION Depending on patient's condition, whether conventional brachytherapy therapy or interpolation therapy is used, the use of the HIPO algorithm to design the treatment regimen without additional treatment time can provide a higher target dose than the manually optimized brachytherapy regimen. Meanwhile, the bladder and rectum doses can be reduced to a certain extent under the premise of ensuring that the target dose met the treatment requirements. There is some increasement for the intestine dose with HIPO planning group, but the dose limits required by the guidelines are still met clinical requirement.

Abstract
Objective: To investigate the predictive value of serum lactate dehydrogenase (LDH) in the prognosis of patients with paraquat (PQ) poisoning, and to provide evidence for early prognosis assessment. Methods: In February 2022, 50 patients with PQ poisoning who completed serum LDH detection admitted to the Department of Emergency Medicine, the First Affiliated Hospital of Wenzhou Medical University from January 2012 to December 2021 were selected as the observation group, and 50 healthy physical examination personnel were randomly selected as the control group. Patients with PQ poisoning were divided into survival group and death group according to the prognosis, and the differences of blood routine routine, liver and kidney function and other indicators in the first admission between the two groups were compared. Multivariate logisitic regression model was established, ROC curve was drawn, and the influencing factors of prognosis of patients with PQ poisoning were analyzed. Results: Compared with the control group, the white blood cell count (WBC), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), LDH, glucose (GLU) and creatinine (Cr) in observation group were significantly increased, while albumin (ALB) and total cholesterol (TC) were significantly decreased (P<0.05). Univariate analysis showed that WBC, elevated LDH (>247 U/L), TBil, ALT, AST and Cr were significantly different between PQ poisoning survival group and death group (P<0.05). Multivariate logisitic regression analysis showed that elevated serum LDH was an independent risk factor for the prognosis of PQ poisoning patients (OR=9.95, 95%CI: 1.34-73.82, P=0.025). The area under the ROC curve of LDH was 0.811 (95%CI: 0.692-0.930). When the cut-off value was 340 U/L, the sensitivity was 0.889 and the specificity was 0.719. Log-rank test showed that there was a statistically significant difference in survival rate between the normal LDH group and the elevated LDH group (P=0.001) . Conclusion: Serum LDH has a good predictive value in evaluating the prognosis of patients with PQ poisoning. Elevated LDH is a risk factor for poor prognosis of patients with PQ poisoning.

Abstract
Purpose This study aimed to identify the effect of different durations of visual target presentation during ciliary-muscle training on children's kinetic visual acuity (KVA), uncorrected distance visual acuity (UDVA), axial length, and accommodative facility. Methods Based on the ciliary-muscle regulation mechanism, an intervention program involving ciliary-muscle training with different durations of visual target presentation combined with physical education classes was designed. The intervention aimed to determine the effect of different ciliary-muscle training durations on children's visual acuity. A total of 153 children aged 10-11 years from a school in Suzhou (a major city located in southeastern Jiangsu Province, East China) were enrolled as participants in this 32-week intervention study. This study measured the participants' UDVA and KVA before, during (after the 16th week), and after (after the 32nd week) the experimental intervention. The accommodative facility was measured during and after the intervention. Results After 32 weeks of the intervention, the KVA and UDVA of each experimental group were significantly improved (p < 0.05). A high percentage in the improvement of KVA was observed in the 3-s and 1-s groups (25.53%, 21.74%), and the highest percentage in the improvement of UDVA was observed in the 3-s group (2.96%). Axial length increased significantly in all groups (p < 0.05), and there was a low percentage increase in the 1-s and 3-s groups (0.82%). The accommodative facility was significantly improved in all experimental groups, with a higher improvement percentage in the 3-s and 1-s groups (3.01% and 2.61%, respectively). After dividing the children in each group according to their visual acuity, the KVA of children in the 1-s group was significantly improved, the UDVA of children with myopia was significantly increased, and the accommodative facility of children with mild and moderate myopia was significantly improved. Moreover, the KVA, UDVA, and accommodative facility of children with mild and moderate myopia in the 3-s group were significantly improved. The KVA of children with emmetropia and the accommodative facility of children with mild and moderate myopia in the 5-s group were also significantly increased. Conclusion In school physical education classes, the 1-s, 3-s, and 5-s ciliary-muscle regulating exercise could effectively improve the kinetic visual acuity, uncorrected distance visual acuity, and accommodative facility of children aged 10-11 years. Among them, the effects of the 1-s and 3-s durations are better than that of the 5-s duration, as it can reduce the growth rate of axial length and achieve better effects among children with mild and moderate myopia.

Abstract
Records of secondary hydrocephalus patients undergoing shunt surgery in the Department of Neurosurgery of Peking Union Medical College Hospital from September 2012 to April 2022 and their clinical characteristics and outcomes were retrospectively reviewed and analyzed. Among 121 patients who received first time shunt placement, the most common causes of secondary hydrocephalus were brain hemorrhage (55, 45.5%) and trauma (35, 28.9%). Cognition decline (106, 87.6%), abnormal gait (50, 41.3%) and incontinence (40, 33.1%) were the most prevalent manifestations. Postoperative central nervous system infection (4, 3.3%), shunt obstruction (3, 2.5%) and subdural hematoma/effusion (4, 3.3%) were the most frequent neurological complications. Overall incidence of postoperative complications was 9% (11 cases) in the current cohort. And 50.5% (54/107) of the patients receiving shunting achieved a Glasgow outcome scale (GOS) score of at least 4. Shunt surgery is preferred for secondary hydrocephalus, especially for secondary normal pressure hydrocephalus. Moreover, it is recommended to complete cranioplasty in staged operation or one-stage operation for the patients with decompressive craniectomy.

Abstract
Tropospheric ozone (O3) is a typical air pollutant with harmful effects on plants, whereas arbuscular mycorrhizal (AM) fungi are ubiquitous plant symbionts that enhance plant resistance to various abiotic stresses. However, whether AM symbiosis decreases plant O3 sensitivity and what the underlying mechanisms remain unclear. In this study, O3-tolerant poplar clone 107 and O3-sensitive poplar clone 546 were used as test plants. An open-top chamber experiment was conducted to investigate the effects of AM inoculation on plant growth and physiological parameters under O3 enrichment. The results showed that O3 enrichment significantly decreased plant biomass and net photosynthetic rate and increased the leaf shedding rate and malondialdehyde concentration of clone 546. Generally, clone 107 was less responsive to O3 enrichment than clone 546 was. Differences in antioxidant enzyme activity, rather than in specific leaf weight or stomatal conductance, were responsible for the differences in O3 sensitivity between the two clones. AM inoculation significantly increased the biomass and decreased the leaf shedding rate and malondialdehyde concentration of clone 107 but had no significant effect on almost all the indexes of clone 546, suggesting a species-specific mycorrhizal effect on plant O3 sensitivity. Mechanistically, AM symbiosis did not significantly affect nutrient uptake, stomatal conductance, or specific leaf weight of poplar but did significantly increase antioxidant enzyme activity. Linear regression analysis of antioxidant enzyme activities and the effect of O3 on growth and physiological parameters showed that AM symbiosis mediated antioxidant enzyme activities to mitigate O3 injury to the two poplars. This study improved the understanding of the protective effects of AM fungi on plants against O3 pollution.

Abstract
Classical first-passage times under restart are used in a wide variety of models, yet the quantum version of the problem still misses key concepts. We study the quantum hitting time with restart using a monitored quantum walk. The restart strategy eliminates the problem of dark states, i.e., cases where the particle evades detection, while maintaining the ballistic propagation which is important for a fast search. We find profound effects of quantum oscillations on the restart problem, namely, a type of instability of the mean detection time, and optimal restart times that form staircases, with sudden drops as the rate of sampling is modified. In the absence of restart and in the Zeno limit, the detection of the walker is not possible, and we examine how restart overcomes this well-known problem, showing that the optimal restart time becomes insensitive to the sampling period.

Abstract
Objective: To understand the characteristics and associated factors of viral nucleic acid conversion in children infected with Omicron variant strain of SARS-CoV-2 in Shanghai. Methods: The clinical symptoms, laboratory results and other data of 177 children infected with SARS-CoV-2 who were hospitalized in Shanghai Children's Hospital, School of Medicine, Shanghai Jiao Tong University (designated hospital for SARS-CoV-2 infection in Shanghai) from April 25 to June 8, 2022 were retrospectively analyzed. According to the chest imaging findings, the children were divided into mild and common type groups. According to their age, the unvaccinated children were divided into<3 years old group and 3-<18 years old group. According to the vaccination status, the children aged 3-<18 year were divided into non-vaccination group, 1-dose vaccination group and 2-dose vaccination group. Comparison between groups was performed by independent sample t-test and analysis of variance, and multivariate linear regression analysis was used for multivariate analysis. Results: Among the 177 children infected with Omicron variant of SARS-CoV-2, 96 were males and 81 were females, aged 3 (1, 6) years. The time of viral nucleic acid negative conversion was (10.3±3.1) days. The 177 children were 138 cases of mild type and 39 cases of common type. Among the children aged 3-<18 years old, 55 cases were not vaccinated, 5 cases received 1-dose and 36 cases received 2-dose vaccination. Among the 36 children who received 2 doses of vaccination, the time of viral nucleic acid negative conversion was shorter in those vaccinated within 6 months than those over 6 months ((7.1±1.9) vs. (10.8±3.0) d, t=-3.23, P=0.004). Univariate analysis showed that the time of nucleic acid negative conversion of SARS-CoV-2 was associated with age, underlying diseases, gastrointestinal symptoms, white blood cell count, proportion of neutrophils, proportion of lymphocytes, and the number of doses of SARS-CoV-2 vaccine (t=3.87, 2.55, 2.04, 4.24, 3.51, 2.92, F=16.27, all P<0.05). Multiple linear regression analysis showed that older age (β=-0.33, 95% CI -0.485--0.182, P<0.001) and more doses of vaccination (β=-0.79, 95% CI -1.463--0.120, P=0.021) were associated with shortened nucleic acid negative conversion time in children, while lower lymphocyte proportion (β=-0.02, 95% CI -0.044--0.002, P=0.031) and underlying diseases (β=1.52, 95% CI 0.363-2.672, P=0.010) were associated with prolonged nucleic acid negative conversion time in children. Conclusion: The children infected with Omicron variant of SARS-CoV-2 with reduced lymphocyte proportion and underlying diseases may have longer time of viral nucleic acid negative conversion,while children with older age and more doses of vaccination may have shorter time of viral nucleic acid negative conversion.

Abstract
Objective: To investigate the effects of low-dose photodynamic therapy on the proliferation, regulation, and secretion functions of human adipose mesenchymal stem cells (ADSCs) and the related mechanism, so as to explore a new method for the repair of chronic wounds. Methods: The experimental research methods were adopted. From February to April 2021, 10 patients (5 males and 5 females, aged 23 to 47 years) who underwent cutaneous surgery in the Department of Dermatology of the First Affiliated Hospital of Army Medical University (the Third Military Medical University) donated postoperative waste adipose tissue. The cells were extracted from the adipose tissue and the phenotype was identified. Three batches of ADSCs were taken, with each batch of cells being divided into normal control group with conventional culture only, photosensitizer alone group with conventional culture after being treated with Hemoporfin, irradiation alone group with conventional culture after being treated with red light irradiation, and photosensitizer+irradiation group with conventional culture after being treated with Hemoporfin and red light irradiation, with sample number of 3 in each group. At culture hour of 24 after the treatment of the first and second batches of cells, the ADSC proliferation level was evaluated by 5-ethynyl-2'-deoxyuridine staining method and the migration percentage of HaCaT cells cocultured with ADSCs was detected by Transwell experiment, respectively. On culture day of 7 after the treatment of the third batch of cells, the extracellular matrix protein expression of ADSCs was detected by immunofluorescence method. The ADSCs were divided into 0 min post-photodynamic therapy group, 15 min post-photodynamic therapy group, 30 min post-photodynamic therapy group, and 60 min post-photodynamic therapy group, with 3 wells in each group. Western blotting was used to detect the protein expressions and calculate the phosphorylated mammalian target of rapamycin complex (p-mTOR)/mammalian target of rapamycin (mTOR), phosphorylated p70 ribosomal protein S6 kinase (p-p70 S6K)/p70 ribosomal protein S6 kinase (p70 S6K) ratio at the corresponding time points after photodynamic therapy. Two batches of ADSCs were taken, and each batch was divided into normal control group, photodynamic therapy alone group, and photodynamic therapy+rapamycin group, with 3 wells in each group. At culture minute of 15 after the treatment, p-mTOR/mTOR and p-p70 S6K/p70 S6K ratios of cells from the first batch were calculated and detected as before. On culture day of 7 after the treatment, extracellular matrix protein expression of cells from the second batch was detected as before. Data were statistically analyzed with one-way analysis of variance and least significant difference test. Results: After 12 d of culture, the cells were verified as ADSCs. At culture hour of 24 after the treatment, the ADSC proliferation level ((4.0±1.0)% and (4.1±0.4)%, respectively) and HaCaT cell migration percentages (1.17±0.14 and 1.13±0.12, respectively) in photosensitizer alone group and irradiation alone group were similar to those of normal control group ((3.7±0.6)% and 1.00±0.16, respectively, P>0.05), and were significantly lower than those of photosensitizer+irradiation group ((34.2±7.0)% and 2.55±0.13, respectively, P<0.01). On culture day of 7 after the treatment, compared with those in normal control group, the expression of collagen Ⅲ in ADSCs of photosensitizer alone group was significantly increased (P<0.05), and the expressions of collagen Ⅰ and collagen Ⅲ in ADSCs of irradiation alone group were significantly increased (P<0.01). Compared with those in photosensitizer alone group and irradiation alone group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photosensitizer+irradiation group were significantly increased (P<0.01). Compared with those in 0 min post-photodynamic therapy group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in 15 min post-photodynamic therapy group were significantly increased (P<0.01), the ratios of p-p70 S6K/p70 S6K of ADSCs in 30 min post-photodynamic therapy group and 60 min post-photodynamic therapy group were both significantly increased (P<0.01). At culture minute of 15 after the treatment, compared with those in normal control group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in photodynamic therapy alone group were significantly increased (P<0.05 or P<0.01). Compared with those in photodynamic therapy alone group, the ratios of p-mTOR/mTOR and p-p70 S6K/p70 S6K of ADSCs in photodynamic therapy+rapamycin group were significantly decreased (P<0.05). On culture day of 7 after the treatment, compared with those in normal control group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photodynamic therapy alone group were significantly increased (P<0.01). Compared with those in photodynamic therapy alone group, the expressions of collagen Ⅰ, collagen Ⅲ, and fibronectin of ADSCs in photodynamic therapy+rapamycin group were significantly decreased (P<0.01). Conclusions: Low-dose photodynamic therapy can promote the proliferation of ADSCs, improve the ability of ADSCs to regulate the migration of HaCaT cells, and enhance the secretion of extracellular matrix protein by rapidly activating mTOR signaling pathway.

Abstract
This study is intended for exploring the effects of the physical activity combined with extra ciliary-muscle training with different frequencies on children's kinetic visual acuity and uncorrected distance visual acuity, and eventually figuring out the optimal frequency of ciliary-muscle training for each physical education class. To do the present research, A total of 160 students aged 10-11 from a school in Suzhou (a major city located in southeastern Jiangsu Province, East China) were randomly selected and divided into control group (n = 33), 15-frequency group (n = 44), 30-frequency group (n = 40) and 60-frequency group (n = 43), and the latter three experimental groups participated in a specially designed physical activity plan based on the training principles of ciliary muscle, while the control group participated in normal physical activity as usual. The experimental intervention period was 16 weeks, and all students' kinetic visual acuity and uncorrected distance visual acuity were measured before and after the experiment. The result showed that the kinetic visual acuity of the students in the 30 and 60-frequency groups got improved significantly after the experiment (p < 0.05), with the highest improvement occurring in the 30-frequency group, while there was no significant change in the 15-frequency group and the control group; The uncorrected distance visual acuity of the students in the 30 and 60-frequency groups was significantly improved after the experiment (p < 0.05), and the improvement range in these two groups was similar. In contrast, there was no significant change in the 15-frequency group, while the control group showed a significant decrease (p < 0.05). Physical activity combined with extra ciliary-muscle training has a positive effect on improving children's vision; at the same time, ciliary-muscle training with different frequencies bring out different outcomes on children's vision improvement, among which ciliary-muscle training with frequency of 30 in each physical education class is the best choice to enhance children's kinetic visual acuity and uncorrected distance visual acuity.

Abstract
Nickel (Ni) contamination imposes deleterious effects on the stability of soil ecosystem. Soil fungal community as a crucial moderator of soil remediation and biochemical processes has attracted more and more research interests. In the present study, soil fungal community composition and diversity under long-term Ni contamination were investigated and fungal interaction networks were built to reveal fungal co-occurrence patterns. The results showed that moderate Ni contamination significantly increased fungal diversity and altered fungal community structure. Functional predictions based on FUNGuild suggested that the relative abundance of arbuscular mycorrhizal fungi (AMF) significantly increased at moderate Ni contamination level. Ni contamination strengthened fungal interactions. Keystone taxa at different Ni contamination levels, such as Penicillium at light contamination, were identified, which might have ecological significance in maintaining the stability of fungal community to Ni stress. The present study provided a deeper insight into the effect of long-term Ni contamination on fungal community composition and co-occurrence patterns, and was helpful to further explore ecological risk of Ni contamination in cultivated field.

Abstract
Concurrent ground-level ozone (O3) pollution and anthropogenic nitrogen (N) deposition can markedly influence dynamics and productivity in forests. Most studies evaluating the functional traits responses of rapid-turnover organs to O3 have specifically examined leaves, despite fine roots are another major source of soil carbon and nutrient input in forest ecosystems. How elevated O3 levels impact fine root biomass and biochemistry remains to be resolved. This study was to assess poplar leaf and fine root biomass and biochemistry responses to five different levels of O3 pollution, while additionally examining whether four levels of soil N supplementation were sufficient to alter the impact of O3 on these two organs. Elevated O3 resulted in a more substantial reduction in fine root biomass than leaf biomass; relative to leaves, more biochemically-resistant components were present within fine root litter, which contained high concentrations of lignin, condensed tannins, and elevated C:N and lignin: N ratios that were associated with slower rates of litter decomposition. In contrast, leaves contained more labile components, including nonstructural carbohydrates and N, as well as a higher N:P ratio. Elevated O3 significantly reduced labile components and increased biochemically-resistant components in leaves, whereas they had minimal impact on fine root biochemistry. This suggests that O3 pollution has the potential to delay leaf litter decomposition and associated nutrient cycling. N addition largely failed to affect the impact of elevated O3 levels on leaves or fine root chemistry, suggesting that soil N supplementation is not a suitable approach to combating the impact of O3 pollution on key functional traits of poplars. These results indicate that the significant differences in the responses of leaves and fine roots to O3 pollution will result in marked changes in the relative belowground roles of these two litter sources within forest ecosystems, and such changes will independently of nitrogen load.

Abstract
Enriched surface ozone (O3) can impose harmful effects on plants. Conversely, arbuscular mycorrhizal (AM) symbiosis can enhance plant tolerance to various environmental stresses and facilitate plant growth. The interaction of AM fungi and O3 on plant performance, however, seldom has been investigated. In this study, alfalfa (Medicago sativa L.) was used as a test plant to study the effects of O3 and AM symbiosis on plant physiology and growth under two O3 levels (ambient air and elevated O3 with 60 nmol·mol-1 O3 enrichment) and three AM inoculation treatments (inoculation with exogenous or indigenous AM fungi and non-inoculation control). The results showed that elevated O3 decreased plant net photosynthetic rate and biomass, and increased malondialdehyde concentration, while AM inoculation (with both exogenous and indigenous AM fungi) could promote plant nutrient acquisition and growth irrespective of O3 levels. The positive effects of AM symbiosis on plant nutrient acquisition and antioxidant enzyme (superoxide dismutase and peroxidase) activities were most likely offset by increased stomatal conductance and O3 intake. As a result, AM inoculation and O3 generally showed no significant interactions on plant performance: although elevated O3 did not diminish the beneficial effects of AM symbiosis on alfalfa plants, AM symbiosis also did not alleviate the harmful effects of O3 on plants.

Abstract
Objective: To evaluate the levels of alveolar bone defects by using cone-beam CT in periodontitis patients with history of orthodontic treatment and to find the special tooth positions, sites and periodontitis stages of alveolar bone defects, so as to provide reference for the formulation of clinical personalized diagnosis and treatment plans. Methods: Thirty patients who were diagnosed as Angle class Ⅱ malocclusion, treated by using labial fixed orthodontic appliances and also diagnosed as periodontitis (orthodontic group) were recuited from January 2009 to June 2019 at the School and Hospital of Stomatology, China Medical University in the present study. They were aged (27.0±5.4) years old (ranged 18-41 years old). Another 60 periodontitis patients without a history of orthodontic treatment matched according to age, gender and severity of periodontitis were selected as control group (non-orthodontic group). They were aged (26.7±5.2) years old (ranged 18-41 years old). Cone-beam CT images were used to measure the heights of the alveolar bone defects at each tooth position of the patients. The difference in the heights of the alveolar bone defects between the orthodontic group and the non-orthodontic group at the same position of the maxillary and mandibular alveolar bones were compared. The specificities of the defect heights in different positions of the maxillary and mandibular alveolar bones and different sites of the same tooth position were analyzed among orthodontic group. The specificities of the different tooth positions of the maxillary and mandibular alveolar bones of the different periodontitis stages among orthodontic group were compared. Results: The heights of the alveolar bone defects in the maxillary canine area and molar area, the mandibular incisor area, the canine area and the premolar area in the orthodontic group were higher than that in the non-orthodontic group, and the differences were statistically significant (P<0.05). In orthodontic group, the most severe teeth in the maxillary and mandibular alveolar bone defects were the canine areas [(3.75±1.00), (3.83±1.10) mm]. Secondly, the more severe tooth positions of the maxillary alveolar bone height defects were the molar area [(3.67±0.84) mm] and the incisor area [(3.39±0.83) mm] and the more severe tooth positions of the mandibular alveolar bone defects were the incisor area [(3.73±1.42) mm] and the molar area [(3.54±0.81) mm]. The height of the alveolar bone defect in the mandibular incisor area was greater than that in the maxillary (P<0.05). The bone defect in the maxillary molar area was severer than that of the mandibular area (P<0.05). The alveolar bone defects in the buccal and lingual sides were mostly larger than that of the mesial and distal sides both in maxillary and mandibular positions except for the maxillary incisor area(P<0.05). The most severe alveolar bone defect position changed with the periodontitis stage. The most severe tooth position of the maxillary in stage Ⅰ periodontitis was in the molar area [(3.26±0.63) mm], whereas the incisor area was the most severe tooth of the mandible [(3.14±1.04) mm]. In addition, among maxillary incisor area, canine area, premolar area, molar area, the most severe alveolar bone defect height was the canine area in stage Ⅱ, Ⅲ, Ⅳ mandibular (P<0.05). Conclusions: In periodontitis patients with a history of orthodontic treatment, the height of the alveolar bone defect was specific to the tooth positions and sites. With the periodontitis stage changing, the most severe defect position changed in both maxillary and mandibular alveolar bones. It is recommended to pay more attention to the alteration of alveolar bone in periodontitis patients with a history of orthodontic treatment and give timely targeted treatment plans.

Abstract
Ground-level ozone (O3) pollution often co-occurs with anthropogenic nitrogen (N) deposition. Many studies have explored how O3 and soil N affect aboveground structure and function of trees, but it remains unclear how belowground processes change over a spectrum of N addition and O3 concentrations levels. Here, we explored the interactive impact of O3 (five levels) and soil N (four levels) on fine and coarse root biomass and biomass allocation pattern in poplar clone 107 (Populus euramericana cv. '74/76'). We then evaluated the modifying effects of N on the responses of tree root biomass to O3 via a synthesis of published literature. Elevated O3 inhibited while N addition stimulated root biomass, with more pronounced effects on fine roots than on coarse root. The root:shoot (R:S) ratio was markedly decreased by N addition but remained unaffected by O3. No interactive effects between O3 and N were observed on root biomass and R:S ratio. The slope of log-log linear relationship between shoot and root biomass (i.e. scaling exponent) was increased by N, but not significantly affected by O3. The analysis of published literature further revealed that the O3-induced reduction in tree root biomass was not modified by soil N. The results suggest that higher N addition levels enhance faster allocation of shoot biomass while shoot biomass scales isometrically with root biomass across multiple O3 levels. N addition does not markedly alter the sensitivity of root biomass of trees to O3. These findings highlight that the biomass allocation exhibits a differential response to environmentally realistic levels of O3 and N, and provide an important perspective for understanding and predicting net primary productivity and carbon dynamics in O3-polluted and N-enriched environments.

Abstract
BACKGROUND Port-wine stain (PWS) is a vascular malformation characterized by progressive dilatation of postcapillary venules, but the molecular pathogenesis remains obscure. OBJECTIVES To illustrate that PWS endothelial cells (ECs) present a unique molecular phenotype that leads to pathoanatomical PWS vasculatures. METHODS Immunohistochemistry and transmission electron microscopy were used to characterize the ultrastructure and molecular phenotypes of PWS blood vessels. Primary culture of human dermal microvascular endothelial cells and in vitro tube formation assay were used for confirmative functional studies. RESULTS Multiple clinicopathological features of PWS blood vessels during the development and progression of the disease were shown. There were no normal arterioles and venules observed phenotypically and morphologically in PWS skin; arterioles and venules both showed differentiation impairments, resulting in a reduction of arteriole-like vasculatures and defects in capillary loop formation in PWS lesions. PWS ECs showed stemness properties with expression of endothelial progenitor cell markers CD133 and CD166 in non-nodular lesions. They also expressed dual venous/arterial identities, Eph receptor B1 (EphB1) and ephrin B2 (EfnB2). Co-expression of EphB1 and EfnB2 in normal human dermal microvascular ECs led to the formation of PWS-like vasculatures in vitro, for example larger-diameter and thick-walled capillaries. CONCLUSIONS PWS ECs are differentiation-impaired, late-stage endothelial progenitor cells with a specific phenotype of CD133+ /CD166+ /EphB1+ /EfnB2+ , which form immature venule-like pathoanatomical vasculatures. The disruption of normal EC-EC interactions by coexistence of EphB1 and EfnB2 contributes to progressive dilatation of PWS vasculatures.

Abstract
Abstract
Introduction: Although only about 5-7% of breast cancers occur in women under 40 years of age, multiple studies have shown that these cancers are more aggressive. In addition issues related to genetic testing and fertility preservation are of particular importance for AYA patients with breast cancer. This retrospective analysis aims to describe various biologic and treatment related factors of an urban AYA population with breast cancer and the differences amongst these factors stratified by African American (AA) versus non-AA race. We will look at factors including stage at diagnosis, hormone receptor status, prevalence of BRCA1/2 mutations, time from diagnosis to treatment, enrollment in clinical trials, and fertility preservation.
Methods: A retrospective study of a population of AYA women with breast cancer seen at two hospitals in Washington D.C. from 2006 to 2015 was performed. Data was collected on age, BRCA1/2 test results, stage at diagnosis, hormone receptor status, time from diagnosis to treatment, enrollment in clinical trial, fertility preservation, and pregnant or breastfeeding status at time of diagnosis. Fisher exact test was used to test the association between two categorical variables. Wilcoxon rank sum test was used to compare time to treatment and stage at presentation between AA and non-AA patients.
Results: A total of 161 AYA patients were evaluated. 54 were identified as AA and 107 as non-AA (88 Caucasians, 13 Asian, 6 Hispanics). Median age was 32 years (20-39) overall; 32 years (23-39) for AA and 33 years (20-39) for non-AA. While the rate of genetic testing was high, significantly fewer AA AYA underwent testing compared to non-AA (74% versus 87% respectively, (p=0.050)) and 10% of AA versus 22% of non-AA were found to have a BRCA1/2 deleterious mutation (p=NS). Clinical trial participation was lower for AA compared to non-AA (57% vs. 76%, p=NS) for those where clinical trials were discussed/offered. Fertility preservation was pursued by 10% of AA vs. 35% of non-AA (p=0.001). Of note, 61% of AA and 34% of non-AA had children at the time of diagnosis (p=0.001). While AA (31%) presented more often with advanced stages of cancer compared to non-AA (19%) this was not statistically significant. Triple negativity was similar in AA AYA (25%) vs. non-AA (22%). The median time to treatment initiation did not vary between AA and non-AA (37 days vs. 36 days, p=NS).
Conclusion: In this retrospective study of an urban population of AYA women with breast cancer, there were no delays in treatment initiation or significant differences between AA and non-AA. When compared to non-AA, AA had a statistically significant lower rate of genetic testing and fertility preservation, although the latest could have been affected by a higher number of nulliparous in non-AA. . Encouragingly, the clinical trial participation of AYA who had previously discussed clinical trials with their physician was very high.

Abstract
The aim of this meta-analysis was to evaluate the effect of telephone-based interventions on prognostic outcomes and health-related quality of life (HRQoL) in breast cancer patients and survivors. A systematic search of the Cochrane Library, Web of science, Medline, EMBASE, CNKI and CBM database was carried out. Randomised, controlled trials (RCTs) examining the effects of telephone-based intervention versus a control group receiving no telephone intervention, on prognostic outcomes and HRQoL with breast cancer were included. A meta-analysis was conducted to quantify the effects of telephone-based interventions on anxiety, depression, fatigue, self-efficiency, physiological function, social-domestic function and quality of life. In total, 14 studies involving 2002 participants were included. Due to the effect of telephone-based interventions, statistically significant results were found on anxiety (standard mean difference [SMD] = -0.16, 95% confidence intervals [CI] [0.01, 0.30], p = .04), self-efficiency (SMD = 0.22, 95% CI [-0.34, -0.10], p = .0004), social-domestic function (SMD = 0.19, 95% CI [-0.35, -0.03], p = .02) and quality of life (SMD = 0.54, 95% CI [-1.00, -0.08], p = .02). Although the effects on depression, fatigue and physiological function were in the expected direction, these effects were not statistically significant (p > .05) based on the insufficient evidence.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the major causes of cancer death worldwide, especially in Eastern Asia. Due to the poor prognosis, it is necessary to further dissect the underlying mechanisms and explore therapeutic targets of ESCC. Recently, studies show that long noncoding RNAs (lncRNAs) have critical roles in diverse biological processes, including tumorigenesis. Increasing evidence indicates that some lncRNAs are widely involved in the development and progression of ESCC, such as HOTAIR, SPRY4-IT1 and POU3F3. An emerging lncRNA, tissue differentiation-inducing nonprotein coding RNA (TINCR), has been studied in human cutaneous squamous cell carcinoma and has critical biological function, but its role in ESCC remains unknown. Here, we evaluated the expression profile of TINCR and its biological function in ESCC. In a cohort of 56 patients, TINCR was significantly overexpressed in ESCC tissues compared with paired adjacent normal tissues. Further, in vitro silencing TINCR via small interfering RNA (siRNA) inhibited the proliferation, migration and invasion of ESCC cells. Meantime, siRNA treatment induced apoptosis and blocked the progression of cell cycle. Taken together, our study suggests that TINCR promotes proliferation, migration and invasion of ESCC cells, acting as a potential oncogene of ESCC.

Abstract
BACKGROUND AND PURPOSE We present the results of a systematic review and meta-analysis examining outcomes of endovascular coiling of wide-neck and wide-neck bifurcation aneurysms with and without stent assistance. The aim of our study was to assess angiographic and clinical outcomes. MATERIALS AND METHODS We performed a comprehensive literature search for all articles on the endovascular coiling of wide-neck and wide-neck bifurcation aneurysms. Studies meeting our inclusion criteria and abstracted data were selected by 2 independent reviewers. Primary outcomes were >6-month complete or near-complete angiographic occlusion, aneurysm recanalization, and aneurysm retreatment. Secondary outcomes included initial complete or near-complete occlusion, long-term good neurologic outcome, procedure-related morbidity, and procedure-related mortality. Data were analyzed by using random-effects meta-analysis. RESULTS In total, 38 studies including 2446 patients with 2556 aneurysms were included. For all wide-neck aneurysms, immediate complete or near-complete occlusion rate was 57.4% (95% CI, 48.1%-66.8%). Follow-up near-complete occlusion rate was 74.5% (95% CI, 68.0%-81.0%). Recanalization and retreatment rates were 9.4% (95% CI, 7.1%-11.7%) and 5.8% (95% CI, 4.1%-7.5%), respectively. Long-term good neurologic outcome was 91.4% (95% CI, 88.5%-94.2%). For wide-neck bifurcation aneurysms, initial complete or near-complete occlusion rate was 60.0% (95% CI, 42.7%-77.3%), long-term complete or near-complete occlusion rate was 71.9% (95% CI, 52.6%-91.1%), and the recanalization and retreatment rates were 9.8% (95% CI, 7.1%-12.5%) and 5.2% (95% CI, 1.9%-8.4%), respectively. CONCLUSIONS Our study of angiographic and clinical outcomes for patients with wide-neck aneurysms demonstrates that endovascular coiling with or without stent-assisted coiling is safe, with low rates of perioperative morbidity and mortality. Initial and long-term angiographic outcomes were generally satisfactory, but not ideal. These data provide some baseline comparisons against which emergent technologies can be assessed.

Abstract
Objective:To investigate the effect of prophylactic migraine therapy in controlling vertigo episode of Meniere's disease. Method:We prospectively collected 16 cases of familial Meniere' disease diagnosed in our vertigo outpatient. The patients were divide into without migraine group (WOM) and with migraine group (WM). Give WM group a prophylactic therapy for migraine and compare within groups about the follow-up results of vertigo episodes. Result:WOM group had better results in controlling vertigo, then the controlling effect equaled after we added a prophylactic therapy for migraine. Conclusion:Combined with prophylactic migraine therapy may have better effect in accompanying migraine patients when controlling familial Meniere's disease.

Abstract
Long noncoding RNAs (lncRNAs) are known to regulate the development and progression of various cancers. However, few lncRNAs have been well characterized in lung adenocarcinoma (LUAD). Here, we identified the expression profile of lncRNAs and protein-coding genes via microarrays analysis of paired LUAD tissues and adjacent non-tumor tissues from five female non-smokes with LUAD. A total of 498 lncRNAs and 1691 protein-coding genes were differentially expressed between LUAD tissues and paired adjacent normal tissues. A novel lncRNA, LUAD transcript 1 (LUADT1), which is highly expressed in LUAD and correlates with T stage, was characterized. Both in vitro and in vivo data showed that LUADT1 knockdown significantly inhibited proliferation of LUAD cells and induced cell cycle arrest at the G0–G1 phase. Further analysis indicated that LUADT1 may regulate cell cycle progression by epigenetically inhibiting the expression of p27. RNA immunoprecipitation and chromatin immunoprecipitation assays confirmed that LUADT1 binds to SUZ12, a core component of polycomb repressive complex 2, and mediates the trimethylation of H3K27 at the promoter region of p27. The negative correlation between LUADT1 and p27 expression was confirmed in LUAD tissue samples. These data suggested that a set of lncRNAs and protein-coding genes were differentially expressed in LUAD. LUADT1 is an oncogenic lncRNA that regulates LUAD progression, suggesting that dysregulated lncRNAs may serve as key regulatory factors in LUAD progression.

Abstract
OBJECTIVE Chronic HCV (hepatitis C virus) infection is recognized as the major cause of mixed cryoglobulinemia. Cryoglobulins continually precipitate and form deposits on the vascular endothelium of small to medium-sized blood vessels, which may progress to vasculitic syndrome. CASE REPORT A 44-year-old female patient with chronic HCV infection presented with purpuras, edema and proteinuria. Her renal findings included microscopic hematuria, moderate proteinuria and endocapillary proliferative glomerulonephritis (EnPGN) on renal biopsy. Serum cryoglobulins comprised mixed monoclonal cryoglobulins characterized by IgM kappa. The serum protein electrophoresis revealed a monoclonal M protein (9.0%). CD19 and CD20-positive B-cell oligo-monoclonal expansion in the bone marrow was revealed. Rapid relief of the clinical symptoms, the disappearance of proteinuria and a sharp decrease in the HCV viral load were observed in our case after one year of interferon therapy. CONCLUSIONS HCV infection-associated extrahepatic manifestations are diverse, which may lead to misdiagnosis. This is the first report of HCV-associated cryoglobulinemic EnPGN and B-NHL, which rapidly responded to interferon.

Abstract
Platinum-induced myelosuppression severely impedes successful chemotherapy in non-small-cell lung cancer (NSCLC) patients. Hence, it is clinically important to identify the patients who are at high risk for severe toxicity to certain chemotherapy. We first carried out a genome-wide scan of 906 703 single-nucleotide polymorphisms (SNPs) to identify genetic variants associated with platinum-induced myelosuppression risk in 333 NSCLC patients with chemotherapy. Then, we replicated 24 SNPs that had P<1 × 10(-4) in another independent cohort of 876 NSCLC patients. With P<0.05 as the criterion of statistical significance, we found that rs13014982 at 2q24.3 and rs9909179 at 17p12 exhibited consistently significant associations with myelosuppression risk in both the genome-wide association studies (GWAS) scan and the replication stage (rs13014982: odds ratio (OR)=0.55, 95% confidence intervals (CIs): 0.41-0.74, P=7.29 × 10(-5) for GWAS scan and OR=0.77, 95% CI: 0.65-0.93, P=0.006 for replication stage; rs9909179: OR=0.51, 95% CI: 0.37-0.70, P=4.60 × 10(-5) for GWAS scan and OR=0.82, 95% CI: 0.68-0.99, P=0.040 for replication stage; both in additive model). In combined samples of genome-wide scan and replication samples, the minor alleles of rs13014982 and rs9909179 remained significant associations with the decreased risk of myelosuppression (rs13014982: OR=0.71, 95% CI: 0.61-0.83, P =1.36 × 10(-5); rs9909179: OR=0.76, 95% CI: 0.65-0.89, P=0.001). Rs13014982 at 2q24.3 and rs9909179 at 17p12 might be independent susceptibility markers for platinum-induced myelosuppression risk in NSCLC patients.

Abstract
Recent evidence indicates that long noncoding RNAs (lncRNAs) have a critical role in the regulation of cellular processes such as differentiation, proliferation, and metastasis. These lncRNAs are dysregulated in a variety of cancers and many function as tumor suppressors; however, the regulatory factors involved in silencing lncRNA transcription are poorly understood. In this study, we showed that epigenetic silencing of lncRNA SPRY4 intronic transcript 1 (SPRY4-IT1) occurs in non-small-cell lung cancer (NSCLC) cells through direct transcriptional repression mediated by the Polycomb group protein enhancer of zeste homolog 2 (EZH2). SPRY4-IT1 is derived from an intron within SPRY4, and is upregulated in melanoma cells; knockdown of its expression leads to cell growth arrest, invasion inhibition, and elevated rates of apoptosis. Upon depletion of EZH2 by RNA interference, SPRY4-IT1 expression was restored, and transfection of SPRY4-IT1 into NSCLC cells resulted in a significant antitumoral effect, both in culture and in xenografted nude mice. Moreover, overexpression of SPRY4-IT1 was found to have a key role in the epithelial-mesenchymal transition through the regulation of E-cadherin and vimentin expression. In EZH2-knockdown cells, which characteristically showed impaired cell proliferation and metastasis, the induction of SPRY4-IT1 depletion partially rescued the oncogenic phenotype, suggesting that SPRY4-IT1 repression has an important role in EZH2 oncogenesis. Of most relevance, translation of these findings into human NSCLC tissue samples demonstrated that patients with low levels of SPRY4-IT1 expression had a shorter overall survival time, suggesting that SPRY4-IT1 could be a biomarker for poor prognosis of NSCLC.
