Abstract
Objective: To analyze the clinical and genetic features of patients with mitochondrial pyruvate carrier deficiency (MPYCD). Methods: This was a case series research. The clinical data, genetic characteristics, and glutamine treatment efficacy of 3 patients diagnosed with MPYCD at the Department of Neurology, Beijing Children's Hospital, Capital Medical University and Department of Pediatrics, Guizhou Provincial People's Hospital, from August 2019 to June 2023 were retrospectively collected. A literature search with "MPC1 gene" "MPC2 gene and" "mitochondrial pyruvate carrier deficiency" as keywords was conducted at the Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure (CNKI) and PubMed (up to June 2023). Clinical and genetic characteristics of patients with MPYCD were summarized. Results: Case 1 was a 3 years and 11 months old boy, while case 2 was a 4 years and 10 months old boy and case 3 was an 8 years and 9 months old girl. Case 2 and case 3 were siblings from one consanguineous family. All 3 patients presented with general developmental delay, growth failure and elevated serum lactate. Cranial magnetic resonance imaging (MRI) showed subtle bilateral symmetrical T2 signal hyperintensity in basal ganglia and thalamus in case 1, but normal in case 2 and 3. Trio-WES revealed case 1 harboring compound heterozygous missense variants c.208G>A (p.Ala70Thr) and c.290G>A (p.Arg97Gln) in MPC1 gene, while case 2 and 3 revealed a homozygous variant c.290G>A (p.Arg97Gln) in the same gene. All 3 cases were diagnosecl as MPYCD. Clinical symptoms including motor ability, cognition and activity endurance were improved in these 3 patients after taking glutamine for 2 years. A total of 5 articles published in English were reviewed, and no Chinese literature was found. Including these 3 cases, 15 cases were enrolled for analysis. Eleven patients carried MPC1 gene variants and 4 cases carried MPC2 gene variants. Except for 3 cases died during prenatal period, 9 of 12 enrolled born cases were onset before 6 months old. The most common clinical symptoms were mental and motor general developmental delay, microcephaly, growth failure and hypotonia. All patients had elevated blood lactate and pyruvate, but the ratio of lactate/pyruvate was normal. Seven patients performed cranial MRI, 3 exhibited non-specific changes, 2 showed bilateral symmetrical T2 signal hyperintensity in basal ganglia and thalamus, and 3 were normal. A total of 5 MPC1 gene missense variants and 2 MPC2 gene variants were identified in 15 cases. Conclusions: Onset age of patients with MPYCD is usually within 6 months. The main clinical characteristics are developmental delay, microcephaly and growth failure, accompanied by increased serum lactate and pyruvate. Glutamine supplement could lead to clinical improvements.

Abstract
Objective: To establish an intelligent registration algorithm under the framework of original-mirror alignment algorithm to construct three-dimensional(3D) facial midsagittal plane automatically. Dynamic Graph Registration Network (DGRNet) was established to realize the intelligent registration, in order to provide a reference for clinical digital design and analysis. Methods: Two hundred clinical patients without significant facial deformities were collected from October 2020 to October 2022 at Peking University School and Hospital of Stomatology. The DGRNet consists of constructing the feature vectors of key points in point original and mirror point clouds (X, Y), obtaining the correspondence of key points, and calculating the rotation and translation by singular value decomposition. Original and mirror point clouds were registrated and united. The principal component analysis (PCA) algorithm was used to obtain the DGRNet alignment midsagittal plane. The model was evaluated based on the coefficient of determination (R2) index for the translation and rotation matrix of test set. The angle error was evaluated on the 3D facial midsagittal plane constructed by the DGRNet alignment midsagittal plane and the iterative closet point(ICP) alignment midsagittal plane for 50 cases of clinical facial data. Results: The average angle error of the DGRNet alignment midsagittal plane and ICP alignment midsagittal plane was 1.05°±0.56°, and the minimum angle error was only 0.13°. The successful detection rate was 78%(39/50) within 1.50° and 90% (45/50)within 2.00°. Conclusions: This study proposes a new solution for the construction of 3D facial midsagittal plane based on the DGRNet alignment method with intelligent registration, which can improve the efficiency and effectiveness of treatment to some extent.

Abstract
OBJECTIVE To examine gender differences in suicidal ideation, suicide attempts, and suicide deaths in patients with bipolar disorder. METHODS PubMed, Web of Science, and Embase were systematic searched from inception to March 7, 2023. Two reviewers extract data independently. Demographic data, the number of males and females with bipolar disorder, and the number of individuals with suicidal ideation, suicide attempts, and suicide deaths among participants were extracted. RESULTS The pooled prevalence of suicidal ideation in males and females was 48.0 % and 44.0 %, respectively, and the overall male-to-female ratios present a statistically insignificant result (OR = 0.95, 95%CI = 0.75-1.21) among patients with bipolar disorder. The pooled prevalence of suicide attempts in males and females was 6.7 % and 9.3 %, respectively, and there was a statistically significant lower prevalence among male patients with bipolar disorder (OR = 0.71, 95%CI = 0.67-0.75). However, the pooled prevalence of suicide deaths in males and females was 0.7 % and 0.3 % respectively, and there was a statistically significant higher prevalence among male patients with bipolar disorder (OR = 1.86, 95%CI = 1.63-2.13). LIMITATIONS The included studies were from mainly middle- and high-income countries and used inconsistent measurement tools. Thus, there is a potential for bias in our results. CONCLUSIONS Among patients with bipolar disorder, females were found to have a higher prevalence of suicide attempts, while males have a higher prevalence of suicide deaths. However, there is no significant gender difference in suicidal ideation. Efforts to optimize recognition, treatment, and administration in males and females may reduce gender differences.

Abstract
PURPOSE/OBJECTIVE(S) The current gold standard of care for resectable locally advanced esophageal cancer is neoadjuvant chemoradiotherapy (NCRT) followed by surgery. Given that only 30-40% of patients with esophageal squamous cell carcinoma (ESCC) achieved a pathologic complete response (pCR) following neoadjuvant chemoradiotherapy, it is critical to understand the biological basis of NCRT resistance in esophageal cancer and identify biomarkers for these patients in order to further personalize treatment plans. We aim to depict the biological landscape of ESCC responsiveness and resistance to neoadjuvant chemoradiotherapy. MATERIALS/METHODS Endoscopic biopsied specimens of the primary tumors and paired peripheral blood samples were obtained from 24 patients before neoadjuvant chemoradiotherapy and tested for whole exosome sequencing, RNA sequencing, and DIA mass spectrometry. Genomic data were analyzed for significantly mutated genes, copy number alterations, MSI, TMB, and mutational signatures. Transcriptomics and proteomics data were used to examine differentially activated pathways. GSEA and ActivePathways were used for the single omics level and joint multi-omics analysis, respectively. Tumor microenvironment (TME) characteristics were deconvoluted by xCell upon RNA-seq data. Treatment resistance biomarkers were identified and validated in a separate cohort using mIHC. RESULTS In the study cohort, 54% (13/24) of the patients achieved pCR. WES data suggested that FBXW7 was more frequently mutated in the pCR group (fisher test p-value = 0.029), and the most significant cytoband loss in the pCR group was 9p21.3 (qval = 0.001). Differences in TMB, MSI, and mutational signatures were not significant between groups. Combined transcriptomics and proteomics analysis revealed that type I interferon signaling pathways and RIG-I-like receptor signaling pathways(p<0.05) were enriched in non-pCR tumors. Esophageal cancer cohort RNA-seq data from TCGA verified the correlation between the genetic variances (FBXW7 mutation and 9p21.3 loss) and the decreased expression of type I interferon signaling pathway genes. In TME analysis, tolerogenic dendritic cells and exhausted T cell signatures were significantly enriched in non-pCR tumors, indicating an immunosuppressive status in treatment resistant patients. Based on proteomics PPI network and differential expression genes from RNA-seq data, a biomarker panel consisted of 12 proteins predictive of non-pCR tumors was identified: STAT1, EIF2AK2, MX1, BST2, TRIM21, SAMHD1, IFI44L, GBP1, PARP14, ISG15, IFIT3, and HLA-B. The expression of selected genes was validated by mIHC in an independent cohort. CONCLUSION Through a multiomics approach, we described the biological characteristics of ESCC with distinct responses to neoadjuvant chemoradiotherapy and proposed a panel of 12 proteins as predictive biomarkers for non-pCR patients.

Abstract
Aim: To develop a Cancer Patient Suicidal Ideation Scale (CAPASIS) and test its reliability and validity. Patients & methods: An initial CAPASIS was developed. Clinical assessment was conducted using an adjusted initial scale with 239 cancer patients for item reduction and 253 for scale validation. Results: Item selection analyses resulted in 22 items. The revised model fits were acceptable (normal chi-square [χ2/df] = 1.919; standardized root mean residual [SRMR] = 0.057; root mean square error of approximation [RMSEA] = 0.060; goodness fit index [GFI] = 0.882; adjusted goodness fit index [AGFI] = 0.844; Tucker-Lewis index [TLI] = 0.898; comparative fit index [CFI] = 0.915; incremental fit index [IFI] = 0.917). The Cronbach's alpha coefficient was 0.911. Conclusion: The CAPASIS has good validity and reliability, with a six-factor structure of 'entrapment', 'defeat', 'isolation', 'hopelessness', 'burdensomeness' and 'humiliation', which can help identify patients with suicidal ideation.

Abstract
OBJECTIVE Patients with severe mental illness have a high risk of suicide and frequently living eliminated from mainstream society, but the effects of social support on suicide-related behaviors among this crowd is inconclusive. The present study aimed to explore such effects among patients with severe mental illness. METHODS We implemented a meta-analysis and a qualitative analysis of relevant studies published before February 6, 2023. Correlation coefficients (r) and 95 % CI were selected as the effect size index in meta-analysis. Studies that did not report correlation coefficients were employed for qualitative analysis. RESULTS Out of 4241 identified studies, 16 were identified in this review (6 for meta-analysis, 10 for qualitative analysis). The meta-analysis presented that the pooled correlation coefficients (r) were - 0.163 (95%CI = -0.243, -0.080, P < 0.001), suggesting a negative correlation between social support and suicidal ideation. The subgroup analysis showed that this effect works in all bipolar disorder, major depression, and schizophrenia. Concerning qualitative analysis, social support presented positive effects on reducing suicidal ideation, suicide attempts, and suicide death. The effects were consistently reported in female patients. However, there existed some unaffected results in males. LIMITATIONS The included studies were from middle- and high-income countries and used inconsistent measurement tools, our results may have some bias. CONCLUSIONS The effects of social support in reducing suicide-related behaviors were positive, but it showed better effects in both female patients and adults. Males and adolescents deserve more attention. Future research needs to pay more attention to the implementation methods and effects of personalized social support.

Abstract
BACKGROUND This study aims to discuss the expression of matrix metalloproteinase in wound healing of diabetic foot ulcers and further summarize the strategies of targeted matrix metalloproteinase and its inhibitors in the treatment of diabetic foot ulcers. METHODS Following PRISMA-SCR guidelines, databases (PubMed, Home-PMC-NCBI, CINAHL, Web of Science) were systematically searched from inception to 19 June 2022. Newcastle-Ottawa Scale (NOS) was used to evaluate the bias risk of the included studies. RESULTS Eight studies are finally eligible for our systematic review. The combined data analysis of 8 studies showed that there were no significant difference in age(p = 0.110), duration of diabetes(p = 0.197), glycosylated hemoglobin content(p = 0.489), size(p = 0.133) and depth(p>0.05) of initial ulcer between the ulcer wound healing group and the non-healing group. MMP-1, 2, 8, 9, and TIMP-1, 2 affected the healing of DFUs. In the DFUs healing group, the concentrations of MMP (MMP-1, 2, 8, 9) decreased, and the concentration of TIMP-1 increased. CONCLUSION Our study showed that high levels of MMP-1, 2, 9 delayed the healing of diabetic foot ulcers, and high expression of MMP-8 in tissues improved wound healing. This study also summarized the effective intervention strategies for the treatment of diabetic foot ulcers.

Abstract
BACKGROUND People with serious mental illness are at great risk of suicide, but little is known about the suicide rates among this population. We aimed to quantify the suicide rates among people with serious mental illness (bipolar disorder, major depression, or schizophrenia). METHODS PubMed and Web of Science were searched to identify studies published from 1 January 1975 to 10 December 2020. We assessed English-language studies for the suicide rates among people with serious mental illness. Random-effects meta-analysis was used. Changes in follow-up time and the suicide rates were presented by a locally weighted scatter-plot smoothing (LOESS) curve. Suicide rate ratio was estimated for assessments of difference in suicide rate by sex. RESULTS Of 5014 identified studies, 41 were included in this analysis. The pooled suicide rate was 312.8 per 100 000 person-years (95% CI 230.3-406.8). Europe was reported to have the highest pooled suicide rate of 335.2 per 100 000 person-years (95% CI 261.5-417.6). Major depression had the highest suicide rate of 534.3 per 100 000 person-years (95% CI 30.4-1448.7). There is a downward trend in suicide rate estimates over follow-up time. Excess risk of suicide in males was found [1.90 (95% CI 1.60-2.25)]. The most common suicide method was poisoning [21.9 per 100 000 person-years (95% CI 3.7-50.4)]. CONCLUSIONS The suicide rates among people with serious mental illness were high, highlighting the requirements for increasing psychological assessment and monitoring. Further study should focus on region and age differences in suicide among this population.

Abstract
BACKGROUND Suicide becomes a widespread public health concern. Cognitive-behavioral therapy (CBT) is used to correct negative thoughts and behaviors of patients at risk of suicide. The aim of this research is to summarize and evaluate the existing evidence to explore the impact of CBT on suicide. METHOD We conducted a systematic searched in PubMed, Web of Science, Cochrane database from the first available year to March 2021. The methodological quality was evaluated by AMSTAR-2 tool, and the evidence quality was evaluated by GRADE classification. We summarized all the comparative effects of CBT on suicide, and used forest plots to describe the impact of CBT on suicide related outcomes included suicidal ideation, suicide attempts. The random effects model was used to summarize data. RESULTS Nine systematic reviews and meta-analysis were included. Most of the systematic reviews and meta-analysis were of medium methodological and evidence quality. The impact of CBT on suicide outcomes could be divided into the following two categories: CBT reduced levels of suicidal ideation (SMD -0.28, 95 % CI -0.36 to -0.21), CBT relieved suicide attempts (RR 0.77, 95 % CI 0.69 to 0.87). CONCLUSION Based on the current evidence, CBT could relieve suicide, including suicide ideation, suicide attempts. CBT is scalable and cost-effective. It is helpful for health professionals to formulate personalized CBT programs, promote clinical and community applications and integrate them into comprehensive suicide interventions and prevention strategies.

Abstract
Adolescent depression is becoming a public health problem. In this study the association between depressive symptoms and internet usage time in adolescents was examined, with data collected from the China Education Tracking Survey (CEPS). The survey is publicly available and carried out nationwide. A logistic regression analysis was conducted with odds ratios (OR) and 95% confidence intervals (CI), the subgroup analysis examined the relationships between internet usage time and depressive symptoms. A total of 10,705 adolescents were involved, where 46.4% of them are caught by the internet for more than two hours per day. Adolescents keeping on the internet for 6-8 h per day were reported to have higher odds of depressive symptoms than adolescents who were free from it with the confounders of individual, family, and school adjusted, which were observed among groups with a medium family economic status without living with their father and with a sleep time less than nine hours. The results revealed that adolescents spending more time online had a higher risk of experiencing depression symptoms. This study suggested that it is helpful for mental health professionals to evaluate and develop prevention interventions for depressive symptoms in adolescents promptly through monitoring and managing online time.

Abstract
Little is known about the efficacy and safety of angiogenesis inhibitor therapy in patients with melanoma. The objective of this study was to assess the possible benefits and harms of angiogenesis inhibitor therapy in patients with melanoma. Electronic databases of PubMed and Web of Science were searched from inception to January 2020. Randomized controlled trials (RCTs) that investigated the efficacy and safety of angiogenesis inhibitor therapy in patients with melanoma were included. Primary outcomes were overall survival (OS) and progression-free survival (PFS), reported as hazard ratios (HRs). Secondary outcomes were disease control, objective response, and adverse events, reported as odds ratios (ORs), and trial sequential analysis (TSA) was also performed. We identified seven trials with 3185 patients. There was no significant difference in OS [HR, 0.99; 95% confidence interval (CI), 0.90-1.09] or PFS (HR, 0.91; 95% CI, 0.83-1.00) between the treatment groups. No significant effect of angiogenesis inhibitor therapy was identified on disease control (OR, 1.23; 95% CI, 0.97-1.55) or objective response (OR, 1.27; 95% CI, 0.99-1.62). TSA showed that the sample size for analysis of disease control was sufficient. Additionally, angiogenesis inhibitor therapy increased risks of hypertension, neurological symptoms, and diarrhea. Angiogenesis inhibitor therapy makes no significant improvement in OS or PFS in patients with melanoma and even causes an increased risk of important adverse events. Therefore, angiogenesis inhibitor therapy is not recommended for the treatment of melanoma.

Abstract
Objective: To explore the establishment of an efficient and automatic method to determine anatomical landmarks in three-dimensional (3D) facial data, and to evaluate the effectiveness of this method in determining landmarks. Methods: A total of 30 male patients with tooth defect or dentition defect (with good facial symmetry) who visited the Department of Prosthodontics, Peking University School and Hospital of Stomatology from June to August 2021 were selected, and these participants' age was between 18-45 years. 3D facial data of patients was collected and the size normalization and overlap alignment were performed based on the Procrustes analysis algorithm. A 3D face average model was built in Geomagic Studio 2013 software, and a 3D face template was built through parametric processing. MeshLab 2020 software was used to determine the serial number information of 32 facial anatomical landmarks (10 midline landmarks and 22 bilateral landmarks). Five male patients with no mandibular deviation and 5 with mild mandibular deviation were selected from the Department of Orthodontics or Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from June to August 2021. 3D facial data of patients was collected as test data. Based on the 3D face template and the serial number information of the facial anatomical landmarks, the coordinates of 32 facial anatomical landmarks on the test data were automatically determined with the help of the MeshMonk non-rigid registration algorithm program, as the data for the template method to determine the landmarks. The positions of 32 facial anatomical landmarks on the test data were manually determined by the same attending physician, and the coordinates of the landmarks were recorded as the data for determining landmarks by the expert method. Calculated the distance value of the coordinates of facial anatomical landmarks between the template method and the expert method, as the landmark localization error, and evaluated the effect of the template method in determining the landmarks. Results: For 5 patients with no mandibular deviation, the landmark localization error of all facial anatomical landmarks by template method was (1.65±1.19) mm, the landmark localization error of the midline facial anatomical landmarks was (1.19±0.45) mm, the landmark localization error of bilateral facial anatomical landmarks was (1.85±1.33) mm. For 5 patients with mild mandibular deviation, the landmark localization error of all facial anatomical landmarks by template method was (2.55±2.22) mm, the landmark localization error of the midline facial anatomical landmarks was (1.85±1.13) mm, the landmark localization error of bilateral facial anatomical landmarks was (2.87±2.45) mm. Conclusions: The automatic determination method of facial anatomical landmarks proposed in this study has certain feasibility, and the determination effect of midline facial anatomical landmarks is better than that of bilateral facial anatomical landmarks. The effect of determining facial anatomical landmarks in patients without mandibular deviation is better than that in patients with mild mandibular deviation.

Abstract
The objectives of the study were to review the articles to identify (a) the epidemiology of systemic lupus erythematosus (SLE) and coronavirus disease 2019 (COVID-19); (b) the clinical characteristics of SLE patients with COVID-19; (c) the treatment of COVID-19 in SLE patients; and (d) the impact of COVID-19 pandemic on SLE patients. PubMed was systematically reviewed for literature published from December 2019 to June 2021. Our search was limited to human studies, with language restriction of English. Studies were included if they reported COVID-19 in SLE patients. Our systematic review included 52 studies. The prevalence of COVID-19 infection ranged from 0.0% to 18.1% in SLE patients, and the hospitalisation rates ranged from 0.24% to 10.6%. COVID-19 infection is likely to mimic SLE flare. Hydroxychloroquine (HCQ) was ineffective in prevention of COVID-19, and SLE patients with COVID-19 faced difficulty in healthcare access, had financial constraints and suffered from psychological distress during the pandemic. The pandemic had a significant effect on mental and physical health. Adequate healthcare access, along with containment policies, social distancing measures and psychological nursing was required.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most severe malignant tumors worldwide. Lobectomy and systematic nodal dissection remain the standard treatment for stageⅠNSCLC. Stereotactic body radiotherapy (SBRT) has become the standard treatment for medically inoperable patients. Though the prognosis of stage Ⅰ NSCLC patients is generally good, there are still about 20% of patients with local recurrence and distant metastasis. There is significant heterogeneity in the prognosis and failure phenotype of patients, which cannot be precisely distinguished by the pathological TNM classification system. Identification of the risk factors for the prognosis of patients with stage Ⅰ NSCLC is a key step to realize the treatment from experience to precision. Screening the high-risk patients will facilitate to individually develop the adjuvant therapy strategy after surgery or SBRT and improve the overall curative effect. There are many factors that are significantly related to the prognosis of stage Ⅰ NSCLC including individual factors such as gender, age, and systemic inflammatory biomarkers; treatment-related factors such as the extent of surgical resection of the primary tumor and lymph nodes, the choice of different radiation rays, and different dose fractionation; and tumor-related factors such as imaging information, pathology information; and molecular biology information. This review will analyze the treatment failure phenotype and prognostic factors of stageⅠ NSCLC in various perspectives such as individual-, tumor- and treatment-related factors.

Abstract
OBJECTIVE The objective of this study was to establish a nomogram model to predict SI in patients with cancer and further evaluate its performance. METHOD This study was performed among 390 patients in oncology departments of Affiliated Hospital of Nantong University from April 2020 to January 2021. Of these, eligible patients who were diagnosed with cancer were split into training and validation cohorts according the ratio of 2:1 randomly. In the training cohort, multivariate regression was performed to determine the independent variables related to SI. A nomogram was built incorporating these variables. The model performance was evaluated by an independent validation cohort. RESULTS The prevalence of SI in patients with cancer was 22.31% and 19.23% in training and validation cohorts, respectively. The nomogram model suggested independent variables for SI, including depression, emotional function, time after diagnosis, family function and educational status. The area under the curve (AUC) was 0.93 (95%CI, 0.90-0.97) and 0.82 (95%CI, 0.74-0.90) in training and validation cohorts respectively, which indicated good discrimination of the nomogram in predicting SI in cancer patients. The p-value of the goodness of fit (GOF) test was 0.197 and 0.974 in training and validation cohorts respectively, suggesting our nomogram model has acceptable calibration power, and the calibration curves further indicated good calibration power. CONCLUSION In conclusion, the nomogram model for predicting individualized probability of SI could help clinical caregivers estimate the risk of SI in patients with cancer and provide appropriate management.

Abstract
PURPOSE The study aimed to conduct a comprehensive systematic review and meta-analysis of injury incidence in professional skiers and snowboarders. METHODS We systematically searched PubMed, Web of Science, and MEDLINE for studies on injury incidence published from inception to April 2020. Injury data were extracted, alongside information on injury location, severity, type, cause, and sport discipline. Incidence of injuries was presented per 1000 athlete-days, with 95% confidence intervals (95%CIs). RESULTS The search identified 462 articles, and 22 were included in our review. The overall incidence of injuries among professional skiers and snowboarders was 3.49 per 1000 athlete-days (95%CI: 2.97-4.01). Lower extremity had the highest injury incidence (1.54 per 1000 athlete-days, 95%CI: 1.24-1.84). Incidence rates of slight, mild, moderate, and severe injuries were 0.26, 0.31, 0.57, and 0.59 per 1000 athlete-days, respectively. Contusion had the highest incidence rate (1.82 per 1000 athlete-days, 95%CI: 1.01-2.63). The most common cause of injury was contact trauma (3.20 per 1000 athlete-days, 95%CI: 1.32-5.08). Freestyle skiing had the highest incidence rate (6.83 per 1000 athlete-days, 95%CI: 4.00-9.66), and Nordic skiing had the lowest rate (2.70 per 1000 athlete-days, 95%CI: 1.94-3.46). CONCLUSION Professional skiers and snowboarders have a substantial risk of sustaining injuries. Our findings can be used to inform the planning and provision of healthcare for elite participants in different snow sports.

Abstract
The aim of our study was to investigate the suicide rates among childhood cancer survivors and assess factors associated with higher suicide risk. A review of data from Surveillance, Epidemiology, and End Results (SEER) program from 1975 to 2016 was performed for this study. This program is based on the US population and is supported by the US National Cancer Institute (NCI). Survivors diagnosed with childhood cancer were recorded. There were 40 suicides among 567,233 person-years, giving a suicide rate of 7.1 per 100,000 person-years. Compared with cancer diagnosed between 10 and 14 years old, survivors with cancer diagnosed between 0 and 4 years old had lower suicide risk. Females had a lower risk of suicide than males. Compared with survivors of thyroid cancer, the aHRs were 0.16 for acute lymphocytic leukemia, 0.15 for nodal Hodgkin's lymphoma, 0.14 for brain cancers and 0.09 for kidney cancers. Most suicides occurred after 15 years old. Suicide was a problem for survivors, especially those with thyroid cancer. Beside treating patients holistically, early psychological interventions such as communicating effectively, providing social support and follow-up care related to psychological health are needed.

Abstract
OBJECTIVE To quantitatively examine the relationship between social support and suicidal ideation (SI) among patients with cancer and identify the moderators that influence the magnitude of this association. METHODS Publications were searched in PubMed, PsycINFO, EMBASE, Cochrane Library and Chinese National Knowledge Infrastructure from database inception to May, 2020. Correlation coefficients (r) were chosen as the effect size with a random model to evaluate the overall effect size between social support and SI in patients with cancer. To assess statistical heterogeneity, we examined potential moderator variables on the social support and SI. RESULTS A total of 881 studies were identified in initial search, and twelve studies were eligible. A negative, small but significant correlation (r = -0.22, 95% CIs: -0.30,-0.14, p < 0.001) was observed between social support and SI in patients with cancer, with a significant heterogeneity (I2 = 95.24%, Q = 231.27, p < 0.001). Moderator analyses indicated that race/ethnicity (Q(1) = 8.4, p < 0.05) and measurements of social support (Q(3) = 9.78, p < 0.05) and SI (Q(3) = 9.69, p < 0.05) significantly moderate the effect size between social support and SI. CONCLUSION Taken together, we found a negative yet significant association between social support and SI in patients with cancer, which supported the importance of social support for the prevention of SI in patients with cancer.

Abstract
BACKGROUND Growing evidence indicated the higher risk of suicide in cancer survivors compared with general population. Our aim is to systematically quantify the extent of suicide death and identify risk factors associated with the incidence of suicide in cancer patients. METHODS We conducted a meta-analysis of relevant studies published in English or Chinese before May 20, 2020. Suicide rate and the number of suicide death were extracted. Our main outcome was suicide rate per 100,000 person-years with 95% CIs using random-effects model. RESULTS The pooled incidence of suicide death was 39.72 per 100,000 person-years (95%CI, 33.91-46.52, I 2= 99.6%, P <0 .001). The suicide rate for cancer patients was higher in men (57.78, 95%CI, 47.31-70.56) than in women (14.47, 95%CI, 11.27-18.57). For both sexes combined, esophagus cancer had the highest rate of suicide (87.71, 95%CI, 27.42-280.54). By sex, suicide rates ranked first in males and females were pancreas cancer (195.70, 95%CI, 129.55-295.61) and esophagus cancer (18.34, 95%CI, 5.92-56.84), respectively. The highest suicide rate was 61.02(95%CI, 53.66-69.40) in Asia, and Oceania (24.07, 95%CI, 20.78-27.88) had lowest suicide rate. Suicide rate had a downward trend by years after diagnosis, with the first six months after cancer diagnosis clearly standing out (89.33, 95%CI, 50.64-157.58). LIMITATIONS Included studies came from high-income countries and our results might not represent the suicide rate among cancer patients in low- and middle-income countries. CONCLUSIONS The incidence of suicide among cancer patients was high despite the declined trend recent years, which emphasized psychological health aspects of interventions and perfecting suicide prevention programs.

Abstract
Abstract In forensic pathology, the estimation of postmortem interval (PMI) has always been a difficult issue, and there is still lack of effective methods to estimate PMI of corpses in water. Microbial biofilm refers to the microbial population attached to non-biological or biological surfaces by microorganisms during microbial growth, that has a three-dimensional structure, surrounded by extracellular polymers and matrix networks created by itself. A series of community succession phenomena of microorganisms occur during the occurrence and development of microbial population. The microbial community and its succession process of this kind of biofilm attached to the surface of a corpse in water may become a new basis for estimation of the PMI of corpses in water. This review elucidates on the concept, classification, research methods, and influencing factors of biofilm and analyzes its application prospects in PMI estimation of corpses in water, which would provide new ideas for the researches in this field.

Abstract
Recurrence rates of diabetic foot ulcers vary widely in the published literature. The aim of this systematic review is to estimate recurrence rates of diabetic foot ulcers. We did a PubMed search and performed a review of reference lists for studies reporting recurrence of diabetic foot ulcers. The weighted relative risk (RR) and corresponding 95% confidence interval (CI) for recurrence was estimated. Forty-nine studies reporting recurrence of diabetic foot ulcers were included. A pooled estimate for recurrence rate was 22.1% per person-year (py) (95% CI, 19.0-25.2%). Recurrence rate was 24.9% per py in Europe (95% CI, 20.0%-29.7%), 17.8% per py in North America (95% CI, 12.7%-22.9%), 16.9% per py in Africa (95% CI, 4.7%-29.0%), and 17.0% per py in Asia (95% CI, 11.1%-23.0%). Turkey had the highest recurrence rate of 44.4% per py (95% CI, 24.9%-63.9%), and Bangladesh had the lowest of 4.3% per py (95% CI, 2.3%-6.3%). Recurrence rates of diabetic foot ulcers before 2002, between 2002 and 2008, and after 2008 were 22.2% per py (95% CI, 17.6%-26.8%), 21.9% per py (95% CI, 17.0%-26.8%), and 21.8% per py (95% CI, 16.3%-27.2%), respectively. Recurrence rates of diabetic foot ulcers are high. Recurrence rates vary widely in different regions and have decreased recently. More attention towards recurrence of diabetic foot ulcers is urgently required.

Abstract
Abstract Human corpses can be found in a variety of aquatic environments. The decomposition of corpses in aquatic environments is different from those on land. A large number of factors influence the decomposition process in water, therefore postmortem submersion interval (PMSI) is difficult to estimate. To date, while studies on aquatic corpses are obviously fewer than those on terrestrial corpses, there are many problems in practical work. This review summarizes the stages and influencing factors of aquatic corpse decomposition, and introduces the relevant research progress of PMSI estimation based on decomposition stages, postmortem phenomena, aquatic insects, biofilm, and physical and chemical methods, in order to provide reference for aquatic decomposition researches and practices.

Abstract
In the current study, twenty lambs, aged 4 months, half male and half female, were classified into four groups, with five in each group. The experimental three groups of lambs were given intravenous (IV), intramuscular (IM) and subcutaneous (SC) administrations of recombinant ovine interferon-τ (roIFN-τ). The fourth group (normal control) of lambs was given normal saline injections in the same way. After administrations, blood samples were collected from the tested animals at different time points post injection, and the serum titers of roIFN-τ were measured using cytopathic effect (CPE) inhibition bioassay. The results of calculating pharmacokinetic (PK) parameters using DAS software showed that the PK characteristics of roIFN-τ through IV injection conformed to the two-compartment open model, whose half-life of distribution phases (T1/2α) was 0.33±0.034 h and the elimination half-life(T1/2β) was 5.01±0.24 h. However, the PK features of IM injection and SC injection of roIFN-τ conformed to the one compartment open model, whose Tmax were 3.11±0.26 h and 4.83±0.43 h, respectively, together with an elimination half life(T1/2β) of 9.11±0.76 h and 7. 43±0.58 h, and an absorption half-life (T1/2k(a)) of 1.13±0.31 h and 1.85±0.40 h, respectively. The bioavailability of roIFN-τ after IM administration reaches 73.57%, which is greater than that of SC administration (53.43%). These results indicate that the drug administration effect can be preferably obtained following a single dose IM administration of the roIFN-τ aqueous preparation. This study will facilitate the clinical application of roIFN-τ as a potential antiviral agent in future work.

Abstract
Objectives: The meta-analysis was performed to summarize the available evidence and determine the healing effectiveness of autologous platelet-rich gel (APG) on diabetic foot (DF) wounds. Approach: PubMed and The Cochrane Library and CNKI databases were searched to identify prior randomized controlled trials. Methodological qualities of included studies were assessed using Cochrane Handbook for Systematic Reviews of Intervention. Healing rate was considered the primary outcome; the secondary outcomes included healing time and adverse events. Results: Fifteen studies involving a total of 827 subjects were analyzed in the meta-analysis. Considering the primary outcome, the average healing rate in APG group was 85.8% and ranged from 68.4% to 100%. Relatively, the control group was 57.4% and ranged from 18.2% to 75.0%. Eligible studies were compared with a fixed effects model (I 2 = 0.0%, p = 0.496), indicating a higher healing rate with APG (risk ratio [RR] 1.44, 95% confidence interval [CI]: 1.32-1.57, z = 8.50, p < 0.001). The leave-one-out sensitivity analysis is robust. Considering the secondary outcomes, APG therapy needed less time (weighted mean difference -10.75 days, 95% CI: -11.67 to 8.86 days, z = 14.34, p < 0.001) and had fewer adverse events (RR 0.44, 95% CI: 0.25-0.76, z = 2.94, p = 0.003). Innovation: APG therapy is an innovative and effective approach to promote DF wound healing and reduce healing time and adverse events. Conclusion: The meta-analysis demonstrates that APG therapy has a positive effect on the treatment of DF wounds. However, additional well-designed and high-quality studies are needed to reach a conclusion with more confidence.

Abstract
Necrobiome is the main factor causing the cadaver decomposition. Studying the microbial succession during decomposition is one of the main tasks of forensic microbiology. The interactive relationships among cadaver, environment and microorganisms are complicated. The microbial succession study relies on macroscopic monitoring of community composition and the diversity change in each decomposition stage. With the maturity and development of high-throughput sequencing (HTS), the structure and diversity of microbial communities in different environments have been successively revealed. A new breakthrough to explore the cadaveric microorganisms has been opened as well. It has become the research hotspots in forensic microbiology to reveal the microbial succession in the process of cadaver decomposition and to interpret the essence of various decomposition phenomena by using HTS, which can provide a new reference for postmortem interval (PMI) estimation. The present paper reviews studies on PMI estimation by using cadaveric microorganism. Problems and application prospects of forensic microbiology studies are discussed on the basis of the current application of HTS technology in the exploration of microbial succession.

Abstract
The role of smoking for wound healing in patients with diabetic foot has been unclear. This meta-analysis examined the relationship between cigarette smoking and diabetic foot wound healing. Observational studies for the association between smoking and diabetic foot wound healing of patients were systematically searched through PubMed and Wanfang Data, published up to June 2018. Healing rates of wounds were recognized as outcomes. Meta-analysis models were chosen by heterogeneity. A total of 3388 eligible studies were identified, of which 18 met all our inclusion criteria. In the smoking group, healing rate had an average of 62.1%, ranging from 20.0% to 89.6%; in the nonsmoking group, healing rate had an average of 71.5%, ranging from 40.2% to 93.8%. A significant association was found between smoking and the healing of diabetic foot wounds ( z = 3.08; P = .002), with an odds ratio (OR) of 0.70 (95% CI = 0.56-0.88), based on a random-effects model. Meta-regression analyses indicated that the heterogeneity did not come from publication year ( t = -0.50, P = .622) or overall healing rate ( t = 0.16, P = .872). The leave-one-out sensitivity analysis was robust; sensitivity analysis for pooled estimate of adjusted ORs had an OR of 0.20 (95% CI = 0.07-0.56; z = 3.08; P = .002). Subgroup analysis had an OR of 0.62 (95% CI = 0.41-0.95; z = 2.21; P = .027) in retrospective cohort studies and had an OR of 0.75 (95% CI = 0.57-0.99; z = 2.02; P = .043) in prospective cohort studies. Our meta-analysis indicated that smoking had an overall negative effect on the wound healing of diabetic foot individuals. This study provides evidence for the harm of smoking to diabetic foot and may help reduce the medical and economic burden on poor healing of diabetic foot.

Objective: To observe the correlation between Nε-carboxymethyl-Lysine (CML), the main component of advanced glycation end products and the calcification of the anterior tibial artery plaque in patients with diabetic foot post foot amputation. Methods: Sixty patients hospitalized for foot amputation operation due to diabetic foot from June 2012 to June 2016 in the Department of Orthopedics, Affiliated Hospital of Jiangsu University were prospectively recruited.The patients were categorized into mild stenosis (0<stenosis<50%, n=20), moderate stenosis (50%≤stenosis<70%, n=20) and severe stenosis (70%≤stenosis≤100%, n=20) based on the color Doppler ultrasound assessed severity of anterior tibial artery stenosis.The baseline clinical data of patients were collected and anterior tibial artery was isolated.Then, HE staining, O-Cresolphthalein Complexone method, enzymic method and ELASA analysis were then performed to detect the evolution of calcification, arterial calcium content, alkaline phosphatase activity and serum CML concentration, respectively. Results: The results from both color Doppler ultrasound scan before amputation and HE staining after amputation showed that echo intensity as well as spotty blue calcium particles of anterior tibial artery plaque increased significantly in proportion to degree of stenosis and destructed elastic plate of the arterial wall was evidenced in patients with severest stenosis.The content of calcium ((2.3±0.9), (3.9±1.3), (6.6±1.7) μmol/mg, respectively, P<0.001), ALP activity ((102.4±39.4), (202.3±73.4), (483.7±117.9) U/mg, respectively, P<0.001) and serum CML level ((28.9±4.4), (37.9±5.3), (57.3±7.1)μg/L, respectively, P<0.001) increased significantly in proportion to stenosis severity.Pearson correlation analysis showed that serum CML level was positively correlated with the content of calcium (r=0.749, P<0.001) and ALP activity (r=0.923, P<0.001), respectively. Conclusions: Serum CML level is positively correlated with the calcification of anterior tibial arterial plaque in patients with diabetic foot and could be used to evaluate the calcification of anterior tibial arterial plaque and stenosis degree of anterior tibial arterial in these patients.

Abstract
INTRODUCTION Prior studies show promising results of the gastric peroral endoscopic pyloromyotomy (G-POEM) procedure for treatment of refractory gastroparesis. One major technical challenge involved in this procedure is identifying the pyloric muscular ring (PMR). The aim of this study is to establish a reliable method for identification of the PMR during G-POEM. METHODS Fluoroscopy-guided G-POEM was performed by placing an endoclip at the 9 to 11'o clock position at the pylorus for identification of PMR. Conventional G-POEM was performed by observation of blue colored mucosa at the pylorus area as an indirect marker for PMR. The degree of the PMR identification was graded into well identified, identified, and not identified based on the appearance of the PMR. Procedure times were accurately documented. Gastroparesis cardinal symptoms index and gastric emptying scintigraphy were evaluated before and after the procedure. RESULTS Fourteen patients were studied, seven underwent fluoroscopy-guided G-POEM, and seven patients underwent conventional G-POEM. All procedures achieved technical success and no adverse events occurred. In the seven patients who underwent fluoroscopy-guided G-POEM, the PMR was well identified in four patients and identified in three patients. In the seven patients who underwent conventional G-POEM, the PMR was identified in four patients and not identified in three patients. The average time to complete the fluoroscopy-guided G-POEM was significantly shorter than that of the conventional G-POEM. CONCLUSIONS Fluoroscopy-guided G-POEM by placement of an endoclip at the pylorus was a reliable and safe method to direct the orientation of the submucosal tunnel, to facilitate the location of the PMR, and to shorten the procedure time.

Abstract
Toll-like receptor (TLR) 3 mediates antivirus immunity and is involved in asthma exacerbation and development. However, the genetic association between TLR3 and asthma remains unclear. This study aimed to evaluate the effects of polymorphisms within TLR3 on asthma risk and asthma-related phenotypes in the Chinese Han population. A total number of 462 unrelated adult patients with asthma and 398 healthy volunteers were enrolled in this study. The genotypes of tagging single nucleotide polymorphisms (SNPs) in TLR3 gene were determined using multiplex SNaPshot SNP genotyping assays. Case-control and case-only studies were used to assess any links with asthma and asthma-related phenotypes. The results showed that the genetic variants in TLR3 were associated with asthma-related phenotypes, including eosinophil counts, serum immunoglobulin E levels and lung function. However, there was no obvious association between the TLR3 SNPs and asthma susceptibility or asthma severity. TLR3 polymorphisms may play a considerable role in the pathogenesis of asthma. It will help in better understanding the pathogenesis of asthma and development of more effective strategies for the prevention, prediction and treatment of asthma.

Abstract
Oryza officinalis has proven to be a natural gene reservoir for the improvement of domesticated rice as it carries many desirable traits; however, the transfer of elite genes to cultivated rice by conventional hybridization has been a challenge for rice breeders. In this study, the conserved sequence of plant stress-related NAC transcription factors was selected as a probe to screen the O. officinalis genomic transformation-competent artificial chromosome library by Southern blot; 11 positive transformation-competent artificial chromosome clones were subsequently detected. By Agrobacterium-mediated transformation, an indica rice variety, Huajingxian 74 (HJX74), was transformed with a TAC clone harboring a NAC gene-positive genomic fragment from O. officinalis. Molecular analysis revealed that the O. officinalis genomic fragment was integrated into the genome of HJX74. The transgenic lines exhibited high tolerance to drought stress. Our results demonstrate that the introduction of stress-related transformation-competent artificial chromosome clones, coupled with a transgenic validation approach, is an effective method of transferring agronomically important genes from O. officinalis to cultivated rice.

Abstract
Retinitis pigmentosa (RP) is a retinal degenerative disorder that often causes complete blindness. Mutations of more than 50 genes have been identified as associated with RP, including the CACNA1F gene. In a recent study, by employing next-generation sequencing, we identified a novel mutation in the CACNA1F gene. In this study, we used the amplification refractory mutation system (ARMS) and identified a single nucleotide change c.1555C>T in exon 13 of the CACNA1F gene, leading to the substitution of arginine by tryptophan (p.R519W) in a Chinese individual affected by RP. This study actually confirms this novel mutation, and establishes the ARMS technique for the detection of mutations in RP.

Abstract
A facile solvothermal method was developed to fabricate CoS nanoplates using ethylenediamine as solvent. The microstructure characterizations indicate that the CoS nanoplates have well-crystalline hexagonal phase and regular hexagonal or pentagonal shape. The XPS and ICP-AES measurements confirm the chemical composition of nanoplates is S-deficient CoS0.921. Cathodoluminescence spectra of both a large area of the nanoplates and individual nanoplate show broad emission bands centered at 615 nm. Magnetic measurements including magnetization dependence of temperature and magnetic hysteresis loops reveals that the CoS nanoplates exhibit room-temperature ferromagnetic behavior. It is found that intrinsic point defects mainly as V(s), Co(i) and/or the complex defects of V(s) and Co(i) should be responsible for both the broad emission band and the unique ferromagnetism.

Abstract
Using soft-x-ray resonant magnetic scattering in combination with first-principles calculations for noncollinear magnetic configurations we present a new model of the magnetism in ultrathin fcc Fe films on Cu(001). We find the presence of blocks with robust magnetic structure, while the relative directions of the moments of different blocks are sensitive to the detailed atomic structure and temperature. The magnetic noncollinearity is directly demonstrated, which has not been possible so far.

Abstract
We studied tetragonally distorted Fe(1-x)Co(x) alloy films on Rh(001), which show a strong perpendicular anisotropy in a wide thickness and composition range. Analyzing x-ray magnetic circular dichroism spectra at the L_(3,2) edges we found a dependence of the Co magnetic orbital moment on the chemical composition of the Fe(1-x)Co(x) alloy films, with a maximum at x=0.6. For this composition, we observed an out-of-plane easy axis of magnetization at room temperature for film thickness up to 15 monolayers. Since both the magnetic orbital moment and the anisotropy energy show similar composition dependence, it confirms that both quantities are directly related. Our experiments show that the adjustment of the Fermi level by a proper choice of the alloy composition is decisive for the large magnetic orbital moment and for a large magnetic anisotropy in a tetragonally distorted lattice.

Abstract
AIM To investigate the effect of scopoletin on cell proliferation and apoptosis of PC3 cells. METHODS Cell growth curve, MTT assay, and acid phosphatase activity (ACP) were used to determine cell proliferation. Coomassie brilliant blue assay was used to measure the content of protein in cells. Light microscope, transmission electronmicroscope, and fluorescence microscope were used to observe scopoletin-induced morphological changes. Apoptosis rate and cell cycle distribution were determined by flow cytometry. RESULTS The IC50 of scopoletin for inhibiting PC3, PAA, and Hela cell proliferation was (157 +/- 25), (154 +/- 51), and (294 +/- 100) mg/L, respectively. Scopoletin induced a marked time- and concentration-dependent inhibition of PC3 cell proliferation. Scopoletin reduced the protein content and decreased the ACP level in PC3 cells in a concentration-dependent manner. Cells treated by scopoletin showed typical morphologic changes of apoptosis by light microscope, fluorescence microscope, and transmission electronmicroscope. Apoptosis rate was 0.3 %, 2.1 %, 9.3 % and 35 % for scopoletin 0, 100, 200, and 400 mg/L, respectively, and cells in G2 phase decreased markedly after being treated with scopoletin. CONCLUSION Scopoletin inhibited PC3 proliferation by inducing apoptosis of PC3 cells.

Abstract
PURPOSE To correlate the volume of lung irradiated with changes in plasma levels of the fibrogenic cytokine transforming growth factor beta (TGFbeta) during radiotherapy (RT), such that this information might be used to predict the development of symptomatic radiation-induced lung injury (SRILI). METHODS AND MATERIALS The records of all patients with lung cancer treated with RT with curative intent from 1991 to 1997 on a series of prospective normal tissue injury studies were reviewed. A total of 103 patients were identified who met the following inclusion criteria: (1) newly diagnosed lung cancer of any histology treated with RT +/- chemotherapy with curative intent; (2) no evidence of distant metastases or malignant pleural effusion; (3) no thoracic surgery after lung RT; (4) no endobronchial brachytherapy; (5) follow-up time more than 6 months; (6) plasma TGFbeta1 measurements obtained before and at the end of RT. The concentration of plasma TGFbeta1 was measured by an enzyme-linked immunosorbent assay. Seventy-eight of the 103 patients were treated with computed tomography based 3-dimensional planning and had dose-volume histogram data available. The endpoint of the study was the development of SRILI (modified NCI [National Cancer Institute] common toxicity criteria). RESULTS The 1-year and 2-year actuarial incidence of SRILI for all 103 patients was 17% and 21%, respectively. In those patients whose TGFbeta level at the end of RT was higher than the pre-RT baseline, SRILI occurred more frequently (2-year incidence = 39%) than in patients whose TGFbeta1 level at the end of RT was less than the baseline value (2-year incidence = 11%, p = 0.007). On multivariate analysis, a persistent elevation of plasma TGFbeta1 above the baseline concentration at the end of RT was an independent risk factor for the occurrence of SRILI (p = 0.004). The subgroup of 78 patients treated with 3-dimensional conformal radiotherapy, who consequently had dose-volume histogram data, were divided into groups according to their TGFbeta1 kinetics and whether their V(30) level was above or below the median of 30%. Group I (n = 29), with both a TGFbeta1 level at the end of RT that was below the pre-RT baseline and V(30) < 30%; Group II (n = 35), with a TGFbeta1 level at the end of irradiation that was below the baseline but a V(30) > or = 30% or with a TGFbeta1 level at the end of RT that was above the pre-RT baseline but V(30) < 30%; Group III (n = 14), with both a TGFbeta1 level at the end of RT that was above the baseline and V(30) > or = 30%. A significant difference was found in the incidence of SRILI among these three groups (6.9%, 22.8%, 42.9%, respectively, p = 0.02). CONCLUSIONS (1) An elevated plasma TGFbeta1 level at the end of RT is an independent risk factor for SRILI; (2) The combination of plasma TGFbeta1 level and V(30) appears to facilitate stratification of patients into low, intermediate, and high risk groups. Thus, combining both physical and biologic risk factors may allow for better identification of patients at risk for the development of symptomatic radiation-induced lung injury.

Abstract
PURPOSE A retrospective study was carried out to evaluate the impact of overall treatment time (OTT) on the results of radiation therapy for non-small cell lung cancer (NSCLC). MATERIALS AND METHODS From Jan. 1990 to Dec. 1996, 256 patients with stages I-IIIb NSCLC entered this analysis. All patients received definitive radiotherapy. Biologically effective dose (BED) was used to standardize the irradiation effects. The correlation between OTT and local progression-free survival was analyzed by linear-regression and Cox proportional hazard models. The prognostic variables for survival and distant metastasis were also briefly studied. RESULTS OTT had been shortened in 64 patients because of an accelerated hyperfractioned irradiation, while OTT was prolonged i n 114 patients due to interruptions of irradiation courses. The main ca uses of interruption were machine breakdown or delayed preparations of c errobend block for boost fields (55%), holidays (11%) and treatment toxi city and side effects (34%). Patients tre ated with prolonged OTT (> 45 days) had significant poorer local progression-free survival than whom with OTT of </=45 days, 1, 3 and 5 year actuarial local progression-free survivals being 49, 17 and 15% for the former, and 74, 35 and 25% for the latter, respectively (P<0.001). BED-T that contained the factor of OTT correlated directly to local controls, which implied that BED-T represented radiobiological effects accurately, in other words, OTT had played a role in determining the radiobiological effects. Linear-regression on 103 cases treated with BED of 80-85 Gy(10) showed that 3 year local progression-free survival decreased by 9% per week with prolongation of OTT, or vice versa it increased by 9% per week with shortening OTT in an OTT range of 30-76 days. Cox multivariate analyses confirmed that OTT was an independent prognostic factor for local controls. CONCLUSION OTT may have played an important role in determining local controls in radiotherapy for NSCLC. One should always keep in mind to make the OTT as short as possible, provided the patients can tolerate it, and to reduce irradiation interruptions for whatever reasons to a minimum.

Abstract
This study was designed to determine whether patients taking angiotensin-converting enzyme (ACE) inhibitors while receiving radiation therapy for lung cancer are protected from developing symptomatic radiation pneumonitis. The records of 213 eligible patients receiving thoracic irradiation for lung cancer with curative intent at Duke University Medical Center from 1994-1997 were reviewed. Of the 213 patients, 26 (12.2%) were on ACE inhibitors (usually for the management of hypertension) during radiotherapy (group 1); the remaining 187 patients (group 2) were not. Patients were irradiated, with fields shaped to protect normal tissues, with total doses of 50-80 Gy. After treatment, patients were generally followed every 3 months for 2 years, then every 6 months thereafter. Symptomatic radiation pneumonitis was scored according to modified National Cancer Institute Common Toxicity Criteria (i.e., radiographic changes alone were not sufficient for the diagnosis of pneumonitis). There was no difference in the incidence of pneumonitis between the two groups (P = 0.75). Fifteen percent of the patients on ACE inhibitors (group 1) developed symptomatic radiation-induced lung injury compared to 12% of the patients not receiving these drugs (group 2). Although patients in group 1 tended to develop pneumonitis slightly sooner than did patients in group 2, this difference also was not significant (P = 0. 8). Within the dose range prescribed for treating hypertension, ACE inhibitors do not appear to either decrease the incidence or delay the onset of symptomatic radiation pneumonitis among lung cancer patients receiving thoracic irradiation.

BACKGROUND The outcome of treatment in non-small cell lung cancer (NSCLC) remains poor. One of the reasons is that in many patients its biological behavior does not follow a definite pattern, and can not be accurately predicted prior to treatment. In the present study we have examined the significant prognostic predictors. METHODS One hundred and fifty-eight patients with NSCLC entered this study. They received surgery alone (95 cases) or combined therapy with postoperative irradiation (63 cases). Three types of data have been collected: (1) clinical characteristics: age, sex, Karnofsky performance status, weight loss, T stage, and N stage; (2) histopathology studies: histological types, tumor differentiation, status of vascular and lymphatic vessel invasions; (3) laboratory measurements by immunohistochemistry assay: oncoprotein overexpression, including pan-ras, c-myc, neu, epidermal growth factor receptor (EGFR) and p53, and tumor cell proliferation by proliferating cell nuclear antigen (PCNA). RESULTS For the entire group, 5-year actuarial survival, local control and distant metastasis rates were 44, 63 and 40%, respectively. In the univariate analyses, T stage, N stage and lymphatic vessel invasion correlated to survival; T stage and N stage to local control; N stage, lymphatic vessel invasion and pan-ras protein positive stain to distant metastasis. When the index of oncoprotein positive stains was used, the higher index was associated with a higher distant metastasis rate. In the multivariate analyses, T stage, N stage and lymphatic vessel invasion could be independent predictors for survival; T stage for local control; N stage, lymphatic vessel invasion and index of positive oncoprotein stains for distant metastasis. CONCLUSIONS Late T and N stages, lymphatic vessel invasion and multi-oncoprotein positive stains would predict poor prognoses for NSCLC.

Abstract
PURPOSE In an attempt to improve local control and survival of nonsmall cell lung cancer (NSCLC), hyperfractionated accelerated radiation therapy (HART) was carried out as a clinical phase I/II trial. METHODS AND MATERIALS HART was delivered by 1.1 Gy/fraction, three fractions per day with intervals of 4 h and five treatment days per week. The clinical tumors were irradiated to 74.3 Gy (72.6-75.9)/66-69 fx, 33 days (29-40) (not corrected for lung density), and the subclinical lesions, to 50.0 Gy (48.4-50.6)/44-46 fx, 33 days (29-40). Sixty-nine patients with NSCLC were enrolled in this study. Nine patients were withdrawn from the study during HART due to different reasons. Sixty patients formed the study for outcome analyses. They were 57 males and 3 females with median age of 61 years (21-77). There were 41 cases of squamous cell carcinoma, 15 cases of adenocarcinoma, and 4 cases of large cell carcinoma. Overall, favorable patients (KPS > or = 70, weight loss < 5% and Stages I, II, IIIa) accounted for 73% (44 of 60) of all patients. Forty-four patients (73%) received adjuvant chemotherapy (DDP + VP16) with median cycles of 1.8 before and/or after HART. In order to compare the outcome of HART with conventional irradiation, 50 NSCLC patients treated by conventional fractionated irradiation (CFI) during the same period were chosen as the basis to evaluate relative effects of HART. They derived from the control group of another clinical trial of hyperfractionated irradiation for NSCLC in the same department. They received median tumor dose of 63.9 Gy (62.8-65.0)/34 fx (32-36), 48 days (45-53). RESULTS 1. Acute and late complications: (a) In HART, 87% of patients (52 cases) developed acute radiation esophagitis: Grade 1-2, 46 cases (77%) and Grade 3, 6 cases (10%), at 2.5 weeks (2-3.5 weeks) after HART began. Five patients with Grade 3 esophagitis had their HART interrupted for <7 days. In CFI, esophagitis was much less (44%,p < 0.05) with 38% of Grade 1-2 and 6% of Grade 3. (b) In HART, acute pulmonary symptoms (RTOG Grade 1-2) occurred in 17% (10 cases), and acute radiation pneumonitis (Grade 3), in 8% (5 cases), while in CFI, they were 24% and 2% (p > 0.05), respectively. Late lung fibrosis (RTOG Grade 1-2) appeared in 20% (12 cases), whereas 18% in CFI (p > 0.05). (c), No other severe acute or late complications have been observed so far in HART. 2. Immediate response. In HART, 20% of patients (12 cases) achieved CR, 60% (36 cases), PR and 20% (12 cases), NR or PD. In CFI, the above three percentages were 10, 28, and 62%, respectively (p < 0.001). 3. Follow-up. The 1-, 2-, and 3-year actuarial survivals were 72, 47, and 28% for HART, and 60, 18, and 6% for CFI, respectively (p < 0.001). Better local control was seen in HART than in CFI with 1-, 2-, and 3-year local control rates being 71, 44, 29%, and 60, 20, and 5%, respectively (p = 0.001). Distant metastases developed less in HART than in CFI. The 1-, 2-, and 3-year distant metastasis rates were 23, 36, and 50% in HART, but 30, 48, and 80% in CFI (p = 0.021). CONCLUSION 1. HART could be tolerated by most of the favorable NSCLC patients. The predominant complication was acute esophagitis. No other severe acute or late complications have been observed so far. 2. HART resulted in better survivals and local controls, and less distant metastases than CFI.

Abstract
From March 1974 to December 1982, 186 patients with laryngeal cancer were treated by operation alone in our hospital. In this series, the average age was 56.5 years. The sex ratio of male and female was 2.9:1. Total laryngectomy comprised 42%, partial laryngectomy 20.4% and postlaryngectomy reconstruction 37.6%. The 3 and 5 year survival rates were 75% and 74% for glottic cancer, 67% and 61% for supraglottic cancer, 67% and 67% for infraglottic cancer, 70% and 38% for transglottic cancer. The authors believe that, at present, operation is the main method of treatment. For early laryngeal cancer, partial laryngectomy is indicated for better postoperative functions in addition to higher survival rate. In advanced laryngeal cancer, total laryngectomy and other radical operation as well as combined therapy are advocated.
