Abstract
Xujiang School of acupuncture and moxibustion has a long history with distinctive academic characteristics and regional influence. Xujiang School, originated from Xi Hong in Song Dynasty, is the oldest acupuncture and moxibustion school recorded in Chinese history. Later, it was passed down from family to family for more than ten generations. The tenth generation Xi Xinqing passed it on to Chen Honggang and gradually evolved into a school of acupuncture and moxibustion with regional characteristics and a certain national influence. In terms of academic characteristics, doctors in Xujiang School kept innovating based on the Classics.Its acupuncture and moxibustion academic ideas including reinforcement and reduction , point selection and searching for the primary cause of disease in treatment have had an important impact on contemporary acupuncture in clinic.

Abstract
Pentraxins3 (PTX3) is an acute-phase protein of the pentraxin family that is synthetized and stored in a variety of cells. As an important mediator of innate immunity, PTX3 is rapidly released during microbial invasion and inflammatory response. It promotes the recognition of pathogens by myeloid cells through regulating complement activation. Recent studies have indicated that PTX3 concentrations in peripheral blood or tissues increase rapidly after infection, and the increased level is associated with the severity of the disease. Thus, PTX3 appears to be a vital clinical biomarker in the diagnosis and prognosis of pulmonary infectious diseases.

Abstract
Measurement bias (MB) has been described in causal structures but is still not entirely clear. In practice, the correctness of substitution estimate (SE) of effect is a prerequisite for causal inference, usually based on a bidirectionally non-differential misclassification between the measured exposure and the measured outcome. Based on a directed acyclic graph (DAG), this paper proposes a structure for the single-variable measure, where its MB is derived from the choice of an imperfect, "input/output device-like" measurement system. The MB of the SE is influenced both by the measurement system itself and by factors outside the measurement system: while the independence or dependence mechanism of the measurement system still ensures that the MB of the SE is bidirectionally non-differential; however, the misclassification can be bidirectionally non-differential, unidirectionally differential, or bidirectionally differential resulted from the factors outside the measurement system. In addition, reverse causality should be defined at the level of measurement, where measured exposures can influence measured outcomes and vice versa. Combined with temporal relationships, DAGs help elucidate MB's structures, mechanisms, and directionality.

Abstract
Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage Ⅰ surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage Ⅰ, respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ2=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ2=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ2=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ2=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

Abstract
Several micro fungi were gathered from bamboo and palm in Guizhou Province, China. In morphology, these taxa resemble Neomassaria, Roussoella and Oxydothis. Multi-gene phylogenetic analyses based on combined ITS, LSU, SSU, rpb2 and tef1 loci confirmed that two are new geographical records for China, (viz. Roussoellasiamensis, Neomassariafabacearum), while two of them are new to science (viz. Oxydothisfortunei sp. nov. and Roussoellabambusarum sp. nov.). The stromata of Roussoellabambusarum are similar to those of R.thailandica, but its ascospores are larger. In addition, multi-gene phylogenetic analyses show that Oxydothisfortunei is closely related to O.inaequalis, but the J- ascus subapical ring as well as the ascospores of O.inaequalis are smaller. Morphological descriptions and illustrations of all species are provided.

Abstract
Objective: To investigate the clinical manifestations and genetic features of 2 children with Smith-Kingsmore syndrome caused by MTOR gene variation and review the literature. Methods: The clinical data of 2 children carrying MTOR gene variant, diagnosed at Xi'an Children's Hospital from April 2018 to April 2021, were retrospectively summarized."MTOR"and"Smith-Kingsmore syndrome"were used as key words to search at China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, PubMed and OMIM up to August 2021. The characteristics of MTOR gene variation and the clinical phenotype of children with Smith-Kingsmore syndrome were summarized. Results: Two children were both females, aged 1.5 years and 2 years respectively, the onset age were both in infancy. They both had developmental delay, megalencephaly and abnormal face. Both whole exome sequencing revealed a de novo heterozygous missense variant in MTOR gene. One case carried c.5395G>A (p.Glu1799Lys) and the other case carried c.7234G>C (p.Asp2412His). There was no literature of MTOR gene variation in Chinese. So far, a total of 45 cases were reported worldwide with detailed clinical information. Eleven variations in MTOR gene were involved, which were all heterozygous missense mutations. Among them, p.Glu1799Lys was the most common sites (28 cases,62%). Another case carried c.7234G>C (p.Asp2412His) was not reported before. Summarizing the 47 cases (including these 2 cases), 46 cases had developmental delay or intellectual disability, 9 cases had developmental regression,42 cases had megalencephaly, 30 cases had facial malformation,16 cases had hypotonia, 17 cases had autism spectrum disorders, 3 cases had hyperactivity, 3 cases had obsessive compulsive disorder, 13 cases had eye diseases, 11 cases had cutaneous vascular malformation, and 9 cases had hypoglycemia. Conclusions: The main clinical features of Smith-Kingsmore syndrome include megalencephaly, developmental delay or intellectual disability, and facial malformation, which can be combined with epilepsy, autism spectrum disorder, hypotonia, hypoglycemia and so on. The variation of MTOR gene is the cause of Smith-Kingsmore syndrome.

Abstract
Alcoholic hepatitis is a severe and life-threatening systemic inflammatory response syndrome, which has a high incidence and mortality rate worldwide. The severity ranges from asymptomatic liver biochemical disturbances to fulminant liver failure or death; however, there are few effective therapeutic interventions. Maddrey discriminant function not only predicts short-term mortality, but it also guides clinicians to choose appropriate alcoholic hepatitis-specific treatments. Alcohol abstinence, nutritional support, psychological counseling, and infection prevention remain the cornerstones for alcoholic hepatitis treatment. Corticosteroids remain the mainstay of treatment when patients have a good appetite and normal serum creatinine levels, but early liver transplantation is the only life-saving option for steroid-unresponsive patients. New studies have found that gut microbiota is an important therapeutic targets in patients with alcohol hepatitis, and N-acetylcysteine, granulocyte colony-stimulating factor, and metadoxine as adjunctive therapy have a positive effect on patient survival.

Abstract
Objective: To assess the effects of long-distance march and training on acute knee injury and knee cartilage sub-regions of college students using quantitatively magnetic resonance imaging analysis. Methods: Twenty-seven young male students from freshman classes in the Army Military Medical University were enrolled in September 2019, aged from 17 to 20 (19.48±0.14) years, participated in the whole 8-day, 240 km long-distance march and training. Three-dimensional quantitative MRI was performed on the right knee using high-field MRI before (baseline) and 1 day after (follow-up) march. The assessment indexes included: meniscus and cartilage injury(5-point scale), bone marrow and ligament injury, and joint effusion(3-point scale). Using semi-automatic cartilage segmentation and 3D data post-processing techniques, a total of 21 sub-regions of cartilage volume and thickness were measured in the medial and lateral femur, medial and lateral tibia. Paired-samples t-test was used to compare the changes in quantitative cartilage indices of the knee joint before and after march. Results: In terms of acute knee injuries, medial and lateral meniscus injuries (grade 1-3) occurred in 8 and 9 college students, respectively compared with those before march. Anterior cruciate ligaments injury occurred in 4 college students and developed from grade 0 to grade 1. Bone marrow edema occurred in 10 students and developed from grade 0 to grade 2, and in 5 students from grade 0 to grade 1. Joint effusion occurred in 5 college students and developed from grade 1 to grade 2 (all P<0.05). In terms of quantitative analysis of cartilage subregion of knee joint, the volume of central region of femoral pulley increased [(1.84±0.32) mm3 vs (1.67±0.29) mm3] and the volume of central region of medial femoral condyle decreased [(1.18±0.21) mm3 vs (1.26±0.17) mm3] compared with that before march (all P<0.05); The cartilage thickness of 11 cartilage subregion [(1.37±0.27) mm vs (1.53±0.18) mm], [(1.42±0.25) mm vs (1.54±0.17) mm], [(1.53±0.20) mm vs (1.62±0.20) mm], [(1.72±0.28) mm vs (1.83±0.28) mm], [(1.84±0.45) mm vs (2.04±0.42) mm], [(2.20±0.58) mm vs (2.46±0.50) mm], [(1.74±0.19) mm vs (1.85±0.21) mm] [(1.45±0.21) mm vs (1.58±0.16) mm], [(1.81±0.22) mm vs (1.91±0.15) mm], [(1.44±0.13) mm vs (1.53±0.15) mm] was thinner than that before march (all P<0.05).

Abstract
Quetiapine is a psychotropic drug. Excessive use of quetiapine may lead to drowsiness, blurred vision, respiratory depression, hypotension and extrapyramidal reactions. Acute respiratory distress syndrome (ARDS) is rare due to overdose of quetiapine. On 14 February 2020, a patients with coma, respiratory arrest and hypotension due to overdose of quetiapine were admitted to our hospital. After receiving mechanical ventilation、plasma adsorption and anti-inflammatory treatment, the patient's consciousness turned clear, the machine was successfully removed and extubated, and the patient's condition was improved and discharged from hospital. We analyzed the clinical data of the patient with quetiapine poisoning, and discussed the clinical symptoms and chest CT characteristics of ARDS caused by quetiapine poisoning, in order to improve the understanding of quetiapine poisoning and improve the success rate of rescue.

Abstract
Objective: To investigate the research trend and scope of prevention of central venous catheter-related bloodstream infection (CRBSI) in burn patients. Methods: The scoping review method was adopted. Pre-retrieval was carried out with search terms of ", , " and "central venous catheter, infection, catheter-related bloodstream infection, burn". On the basis of pre-retrieval, different retrieval formulas were formulated to retrieve researches related to central venous CRBSI in burn patients in China National Knowledge Internet, Wanfang Database, VIP Database, PubMed, Embase, CINAHL, and Cochrane Library from the establishment of each database to August 2020. Data were extracted from the included literature, including the first author, research publication time, research country, research type, diagnosis basis and intervention measures of central venous CRBSI, research sample selection, incidence related to infection, and research conclusion. Results: A total of 20 randomized controlled trials, quasi-experimental studies, case-control studies, cohort studies, and implementation researches published in 1990-2020 were included in this study with the first authors from China, the United States of America, or Argentina. The diagnostic bases for central venous CRBSI in burn patients were not uniform in the included literature, including adopting the Guidelines of American Centers for Disease Control and Prevention, Diagnostic Criteria for Nosocomial Infection, and other diagnostic criteria without specifying the source. The intervention measures included the use of new materials such as antibiotics coated catheter and ethanol impregnated port protectors, multidisciplinary cooperation, and comprehensive preventive measures. The sample size in the included literature was small, and the sample selection was different, including the number of patients and the the number of placement of central venous catheter. The outcome indicators for infection in the included literature were diversified. The incidence per 1 000 days of central venous CRBSI was 20.41‰-29.1‰ of patients in control group in China, the incidence per 1 000 days of central venous CRBSI was mostly <16.6‰ in control group in foreign countries, and the incidence of central venous CRBSI was decreased to varying degrees after implementing the corresponding intervention measures. Related research conclusions showed that new materials, multidisciplinary cooperation, and comprehensive preventive measures had good effects on prevention of central venous CRBSI in burn patients. Conclusions: The researches on prevention of central venous CRBSI in burn patients in China start early and the research types are diversified. The diagnostic criteria of central venous CRBSI in burn patients are not uniform, intervention measures have shifted from standardizing relevant operational measures to exploring the prevention effects of new materials, multidisciplinary cooperation, and multiple measures, and the latter has good effects on preventing central venous CRBSI in burn patients.

Abstract
Objective: To systematically summarize and assess risk prediction models for occurrence of cervical cancer and to provide evidence for selecting the most reliable model for practice, and guide cervical cancer screening. Methods: Two groups of keywords related to cervical cancer and risk prediction model were searched on Chinese databases (CNKI, and Wanfang) and English databases (PubMed, Embase, and Cochrane Library). Original articles that developed or validated risk prediction models and published before November 21, 2019, were selected. Information form was created based on the CHARMS checklist. The PROBAST was used to assess the risk of bias. Results: 12 eligible articles were identified, describing 15 prediction models, of which five were established in China. The predicted outcomes included multiple stages from cervical precancerous lesions to cancer occurrence, i.e., abnormal Pap smear (1), occurrence or recurrence of CIN (9), and occurrence of cervical cancer (5), etc. The most frequently used predictors were HPV infection (12), age (7), smoking (5), and education (5). There were two models using machine learning to develop models. In terms of model performance, the discrimination ranged from 0.53 to 0.87, while only two models assessed the calibration correctly. Only two models were externally validated in Taiwan of China, using people in different periods. All of the models were at high risk of bias, especially in the analysis domain. The problems were concentrated in the improper handling of missing data (13), preliminary evaluation of model performance (13), improper use of internal validation (12), and insufficient sample size (11). In addition, the problems of inconsistency measurements of predictors and outcomes (8) and the flawed report of the use of blindness for outcome measures (8) were also severe. Compared with the other models, the Rothberg (2018) model had relatively high quality. Conclusions: There are a certain number of cervical cancer risk prediction models, but the quality is poor. It is urgent to improve the measurement of predictors and outcomes, the statistical analysis details such as handling missing data and evaluation of model performance and externally validate existing models to better guide screening.

Abstract
During an investigation of Xylariaceae from 2019 to 2020, isolates representing eight Nemania (Xylariacese) species were collected from Yunnan, Guizhou and Hainan Provinces in China. Morphological and multi-gene phylogenetic analyses, based on combined ITS, α-actin, rpb2 and β-tubulin sequences, confirmed that six of them are new to science, viz. Nemaniacamelliae, N.changningensis, N.cyclobalanopsina, N.feicuiensis, N.lishuicola and N.rubi; one is a new record (N.caries) for China and one is a known species (N.diffusa). Morphological descriptions and illustrations of all species are detailed. In addition, the characteristics of Nemania are summarised and prevailing contradictions in generic concepts are discussed.

Abstract
Objective: To investigate the clinicopathological, immunohistochemical and molecular features of small round cell sarcoma (SRCS) of the bone and soft tissue, and to compare the diagnostic value of different techniques. Methods: Seventy-two cases of SRCS of the bone and soft tissue diagnosed at People's Hospital, Peking University from January 2016 to March 2020 were recruited and retrospectively analyzed for pathological morphology, immunophenotype and fluorescence in situ hybridization (FISH) data. Next generation sequencing (NGS) was performed on 13 difficult cases. Results: In the study cohort, the patients ranged in age from 4-55 years, with a male predominance. The most Ewing's sarcomas and osteosarcomas occurred in the bone, while CIC-rearranged sarcomas, BCOR-rearranged sarcoma, synovial sarcoma, extraskeletal myxoid chondrosarcoma and FUS-NFATc2 rearranged sarcoma occurred in soft tissue. Histologically, all cases were composed predominantly of small round cells. Most cases were positive for vimentin and CD99, and showed a variable reactivity for neurogenic markers. Muscle marker and epithelial marker were negative for most cases. Combined with clinical features, histopathologic findings, immunophenotype, FISH and NGS, we diagnosed 46 Ewing sarcomas, 14 osteosarcomas, 3 CIC-rearranged sarcomas, 1 BCOR-rearranged sarcoma, 1 synovial sarcoma, 1 clear cell soft tissue sarcoma, 1 extraskeletal myxoid chondrosarcoma, 1 FUS-NFATc2 rearranged sarcoma, and 4 undifferentiated small round cell sarcomas. Conclusions: SRCS of bone and soft tissue is a group of malignant mesenchymal tumors based on morphological features. Most cases can be diagnosed with a combination of clinical characteristics, morphological features and immunohistochemical phenotype, while some cases require such further tests as FISH and NGS technologies, and NGS can be useful in diagnosing and categorizing SRCS.

Abstract
Objective: To further improve the awareness of the clinical feature of acute diquat poisoning. Methods: A retrospective analysis was performed on 4 cases of acute diquat poisoning with epileptoid seizure as the main clinical manifestation, which were admitted and diagnosed by the Characteristic Medical Center of Chinese People's Armed Police Force from January 1, 2017 to December 31, 2019. Take "Diquat" or "Deiquat" or "Reward" as keyword search for CNKI, Pubmed, and EMbase in both Chinese and English. The date of literature retrieval was from the database founding to December 31, 2019. Results: Of the 4 patients, 3 were male and 1 female, with an average age of 28 years (22-33 years) . The estimated dose was 8-20 g. All patients were treated with gastric lavage, catharsis, fluid replacement, blood perfusion, and in the early stage of treatment of epileptic seizures, the initial routine antiepileptic drugs had poor effect. Then propofol and midazolam were injected into the treatment. The epilepsy was relieved, but the condition deteriorated rapidly, and the patients died eventually. The literature search retrieved 3 patients in the 3 literatures included in the study were analyzed, and their clinical course was similar to that of 4 cases in the center. Necropsy was performedon all 3 patients, and the results were cerebral edema, diffuse cerebral edema, and hemorrhage around the basal ganglia. Conclusion: Acute diquat poisoning can cause epileptic seizures. Once it occurs, the disease progresses rapidly and the prognosis is poor. The combination of large dose of sedative drugs can be used to treat epilepsy in order to improve the prognosis.

Abstract
BACKGROUND Assessments of cortical development and identifying factors that may result in a poor prognosis for fetuses with isolated mild ventriculomegaly (IMVM) is a hot research topic. We aimed to perform a constant, detailed assessment of cortical development in IMVM fetuses using ultrasound and determine whether asymmetric cortical development occurred. Moreover, we aimed to estimate the prognosis of IMVM fetuses and compare the difference in the prognosis of IMVM fetuses presenting symmetric and asymmetric cortical maturation. METHODS IMVM was diagnosed by regular ultrasound, neurosonography and fetal MRI. Genetic and TORCH examinations were conducted to exclude common genetic abnormalities and TORCH infection of fetuses. Ultrasound examinations were conducted at an interval of 2-3 weeks to record sulcus development in IMVM fetuses using a scoring system. The neonatal behavioral neurological assessment (NBNA), the Ages and Stages Questionnaire, Third Edition (ASQ-3) and the Bayley Scales of Infant Development, First Edition (BSID-I) were performed after birth. RESULTS Forty fetuses with IMVM were included: twenty showed asymmetric cortical maturation and twenty showed symmetric cortical maturation. For IMVM fetuses presenting asymmetric cortical maturation, the mean gestational age (GA) at the first diagnosis of relatively delayed development was 24.23 weeks for the parieto-occipital sulcus, 24.71 weeks for the calcarine sulcus, and 26.43 weeks for the cingulate sulcus. All the sulci with delayed development underwent 'catch-up growth' and developed to the same grade as the sulci of the other hemisphere. The mean GA at which the two sides developed to the same grade was 29.40 weeks for the parieto-occipital sulcus, 29.30 weeks for the calcarine sulcus and 31.27 weeks for the cingulate sulcus. The NBNA, ASQ-3 and BSID-I scores of all patients were in the normal range. CONCLUSIONS IMVM fetuses may show mild asymmetric cortical maturation in the second trimester, but the relatively delayed sulci undergo 'catch-up growth'. The neurodevelopment of IMVM fetuses presenting asymmetric cortical maturation and 'catch-up growth' is not statistically significantly different from IMVM fetuses presenting symmetric cortical maturation.

Abstract
Objective To explore the correlation between 4 tag single nucleotide polymorphisms (Tag SNP) sites (rs7721799, rs32897, rs7718461, rs10062367) of corticotropin releasing hormone binding protein (CRHBP) and schizophrenia and aggressive behavior in the Yunnan Han population. Methods Case-control correlation analysis was used to establish a complex amplification system. Improved multiplex ligase detection reaction (iMLDR) technology was used to detect the genotypes of 4 SNP sites of CRHBP gene of 163 Han schizophrenic patients (including 81 patients with aggressive behavior, 82 patients without aggressive behavior) and 345 healthy Han individuals, which were analyzed statistically by SPSS 19.0, Haploview 4.2 and PHASE 2.1 software. Results There was no correlation between the 3 SNP sites of CRHBP gene and the onset of schizophrenia except for the rs7718461 site (P>0.05). The relative risk of aggressive behavior of patients carrying GG or GA genotype at rs7718461 site were 4.903 times higher than those carrying AA genotype (P<0.05). Conclusion The CRHBP gene may not be associated with the occurrence of schizophrenia in Yunnan Han population, but AA genotype of rs7718461 may reduce the risk of aggressive behavior in schizophrenia patients.

Abstract
Objective: To investigate the significance of plasma pentraxin 3 (PTX3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH). Methods: Plasma PTX3 levels were tested by ELISA in 48 newly diagnosed sHLH patients, 18 healthy volunteers and 9 lymphoma controls in the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2019. Clinical parameters were collected, and the correlations with PTX3 levels were analyzed. Results: PTX3 level in newly diagnosed group was significantly higher than that of healthy control group [16.29(1.17-66.00) vs. 0.76(0.01-7.86) μg/L, P<0.01]. Patients with lymphoma-associated HLH(LHLH) had higher plasma level of PTX3 than Fhose with infection-associated HLH (IHLH) [24.29(3.36-66.00) vs. 9.56(1.17-36.50)μg/L, P<0.05]. Plasma PTX3 levels in 48 sHLH patients were positively correlated with serum ferritin (P<0.05). Receiver operating characteristic (ROC) curve for plasma PTX3 levels of sHLH and healthy controls produced a cutoff value at 3.9 μg/L, with its 86.7% sensitivity and 94.4% specificity. And ROC analysis showed that PTX3 17.5 μg/L was the critical value for diagnosis of LHLH from non-LHLH group, that the sensitivity and specificity were 63.0% and 76.2% respectively. The 1-year overall survival (OS) rate in patients with PTX3≥17.5 μg/L was significantly lower in those with PTX3<17.5 μg/L (18.5% vs. 75.8%, P<0.01). Conclusion: These results indicate the potential of PTX3 as a biomarker for diagnosis and prognosis in patients with sHLH.

Abstract
Ubiquitination signaling is the main pathway of protein degradation in eukaryotic cells. Ubiquitin-proteasome system degrades the ubiquitinated cytoplasmic proteins and lysosome pathway mainly degrades the ubiquitinated membrane proteins. Previous studies have shown that ubiquitination signaling plays a critical role in fatty acids synthesis. In the process of fatty acids import, disruption of ubiquitination could prevent the degradation of fatty acid transport proteins, thereby promoting fatty acids import and milk fat synthesis in bovine primary mammary epithelial cells. In this review, we summarize the signal transduction and regulation mechanism of ubiquitination signaling in milk fat synthesis, which may provide references and new ideas for future research on milk fat traits in dairy cows.

Abstract
OBJECTIVE To analyze the characteristics of patients with progressive muscular atrophy (PMA) and calculate the prevalence of PMA in China in 2016. METHODS A retrospective analysis based on China's urban employee basic medical insurance data and the urban residence basic medical insu-rance data from January 1, 2016 to December 31, 2016 was carried out. Children under 18 years old were excluded. Patients with progressive muscular atrophy were identified by disease names and codes. Subgroup analyses by gender, region and age were carried out to calculate the gender-specific, region-specific and age-specific prevalences. Age-adjusted national prevalence was estimated based on 2010 Chinese census data. Sensitivity analyses were done by only considering the observed cases and by excluding the top 10% provinces regarding the missing rate of diagnostic information, respectively. RESULTS A total of 996.09 million person-years were included in this study, with 518.41 million person-years in males and 477.67 million person-years in females. The age and gender distribution of the study population was similar to that of the 2010 Chinese census data, therefore the study population was nationally representative. The prevalence of PMA in China in 2016 was 0.28 per 100 000 person-years (95%CI: 0.24-0.33), with 0.21 per 100 000 person-years (95%CI: 0.16-0.26) and 0.35 per 100 000 person-years (95%CI: 0.28-0.42) for females and males, respectively. Regional disparity existed in the Chinese PMA prevalence, with the lowest prevalence in Southwest region (0.11 per 100 000 person-years, 95%CI: 0.07-0.15) and the highest prevalence in Northwest region (3.47 per 100 000 person-years, 95%CI: 0.80-7.99). Age trend in the PMA prevalence was not obvious, but the prevalence among those aged 70 years and older was relatively higher. The age-adjusted prevalence based on 2010 Chinese census data was 0.29 per 100 000 person-years (95%CI: 0.27-0.31). The national prevalences calculated by only considering the observed cases and by excluding the top 10% provinces regar-ding the missing rate of diagnostic information were 0.17 per 100 000 person-years (95%CI: 0.14-0.20) and 0.24 per 100 000 person-years (95%CI: 0.20-0.28), respectively. CONCLUSION This study is to calculate the prevalence of PMA among adults in urban China, which can provide basic statistics for the enactment of PMA related medical policies, and clues for the studies on the mechanisms of PMA.

Abstract
Objective: To understand the current status of rare disease related health information release in WeChat official accounts in China. Methods: We used a series of key words containing "rare diseases" and the names of the top 30 rare diseases in hospitalizations in China to search WeChat official accounts. Eligible articles were selected by systematic sampling. All including WeChat official accounts and articles were evaluated to extract the basic information. Results: No relevant WeChat official accounts were found for 14 rare diseases (46.67%). Most of the WeChat official accounts (52.17%) were initiated by patients and patient groups. No significant difference was detected in the total number of articles between the official accounts related with Traditional Chinese Medicine (TCM) and non-TCM related ones, however, the frequency of the monthly information release was significantly higher in TCM related official accounts (P<0.001), while the average reading number of articles was significantly higher in non-TCM related official accounts (P<0.001). Nearly 80% of the WeChat official accounts had navigation menu, and the average reading number of official accounts with menus was larger than those without menus. The top three topics were rare disease diagnosis and treatment knowledge (46.00%), public welfare activity for rare diseases (12.81%) and uncorrelated things (8.65%), while the first three leading topics were cutting-edge information, public welfare activity and patient story, respectively. Conclusions: The scale for rare disease related health information release based on WeChat official accounts in China has been basically formed, but it is still in development stage. Many improvements should be made in their coverage of rare diseases, release frequency, topic and form. It is urgent to establish or recreate some high-quality WeChat official accounts in order to provide precise information and effectively facilitate the prevention and treatment of rare diseases.

Abstract
WSL8 encoding a deoxyribonucleoside kinase (dNK) that catalyzes the first step in the salvage pathway of nucleotide synthesis plays an important role in early chloroplast development in rice. The chloroplast is an organelle that converts light energy into chemical energy; therefore, the normal differentiation and development of chloroplast are pivotal for plant survival. Deoxyribonucleoside kinases (dNKs) play an important role in the salvage pathway of nucleotides. However, the relationship between dNKs and chloroplast development remains elusive. Here, we identified a white stripe leaf 8 (wsl8) mutant that exhibited a white stripe leaf phenotype at seedling stage (before the four-leaf stage). The mutant showed a significantly lower chlorophyll content and defective chloroplast morphology, whereas higher reactive oxygen species than the wild type. As the leaf developed, the chlorotic mutant plants gradually turned green, accompanied by the restoration in chlorophyll accumulation and chloroplast ultrastructure. Map-based cloning revealed that WSL8 encodes a dNK on chromosome 5. Compared with the wild type, a C-to-G single base substitution occurred in the wsl8 mutant, which caused a missense mutation (Leu 349 Val) and significantly reduced dNK enzyme activity. A subcellular localization experiment showed the WSL8 protein was targeted in the chloroplast and its transcripts were expressed in various tissues, with more abundance in young leaves and nodes. Ribosome and RNA-sequencing analysis indicated that some components and genes related to ribosome biosynthesis were down-regulated in the mutant. An exogenous feeding experiment suggested that the WSL8 performed the enzymic activity of thymidine kinase, especially functioning in the salvage synthesis of thymidine monophosphate. Our results highlight that the salvage pathway mediated by the dNK is essential for early chloroplast development in rice.

Abstract
AIMS Ratoon stunting disease caused by Leifsonia xyli subsp. xyli (Lxx) is a bacterial disease that has plagued sugarcane-planting countries for a long time. This study mainly analysed Lxx localization and its effects on sugarcane leaf. METHODS AND RESULTS Badila were inocultated by bacteria of Lxx. It was noted that the number of Lxx cells were rapidly enriched in sugarcane leaves from the 150th to the 210th days of post inoculation (dpi). Lxx infection disrupted the integrity of vascular bundle sheath cells (BSC) in the 'Kranz anatomy' of leaves, resulting in irregular accumulation of starch in vascular BSC of leaves. In situ PCR showed that the Lxx localized in the xylem vessels, mesophyll cell (MC) and BSC as described before in sugarcane leaf, a new niche within the host tissues in the phloem of sugarcane stem. The gene expression and activities of phosphoenolpyruvate carboxylase (PEPC), pyruvate, orthophosphate dikinase (PPDK) and NADP-malic enzyme (NADP-ME) enzymes were lower in Lxx-inoculated sugarcane plants as compared to the MI group. CONCLUSION Lxx infection not only disrupted the structure of vascular BSC in the C4 'Kranz anatomy' of sugarcane leaves, but also affected the activities and gene expression of the key enzymes PEPC, PPDK and NADP-ME in the C4 cycle of sugarcane suggesting a reduction in CO2 fixation. SIGNIFICANCE AND IMPACT OF THE STUDY The effect of Leifsonia xyli subsp. xyli (Lxx) infection on the photosynthetic physiology of sugarcane is currently limited to the evaluation of photosynthetic parameters. This study assessed the impact of Lxx infection on the mechanism of C4 cycle CO2 fixation and to accompanying plant anatomy.

Abstract
目的 探讨继发性噬血细胞性淋巴组织细胞增多症(sHLH)合并毛细血管渗漏综合征(CLS)的临床特征。 方法 回顾性分析2015年1月至2017年12月江苏省人民医院收治的87例sHLH患者的临床及实验室资料,其中21例合并CLS(CLS-sHLH组),66例未合并CLS(非CLS-sHLH组)。比较两组的临床表现、实验室检查、治疗及预后差异。 结果 比较CLS-sHLH组和非CLS-sHLH组患者引起sHLH的病因,差异无统计学意义(P>0.05)。CLS-sHLH组患者ANC、血清纤维蛋白原、白蛋白较非CLS-sHLH组降低,而甘油三酯较非CLS-sHLH组升高(P值均<0.05)。CLS-sHLH组患者均有不同程度水肿、体重增加、低血压、低蛋白血症、少尿及多浆膜腔积液。其中15例患者CLS症状消失,CLS中位好转时间为7(5~14)d。6例患者CLS症状未消失,并于15(6~30)d死亡。CLS-sHLH组中位OS时间低于非CLS-sHLH组(75 d对未达到,P=0.031)。 结论 在sHLH患者中,CLS的发生可能与sHLH的原发病无明显相关。严重的ANC、纤维蛋白原及白蛋白减低,甘油三酯升高,可能是sHLH发生CLS的伴随症状。sHLH合并CLS时预后差。

Abstract
In a previous genome-wide association study on milk production traits in Chinese Holstein population, we discovered VPS28 gene was highly expressed in mammary gland tissue. Further, a -58C>T mutantion at the 5°-UTR of the gene was significantly associated with milk fat content traits. However, its regulation on milk fat content is still uncertain. In this study, we explored the effect of this -58C>T mutation on VPS28, and found that it could significantly reduce promoter activity of VPS28 gene. To identify the potential function of this SNP, we performed RNAi experiments to knockdown VPS28 gene in BMECs and examined the general effects of VPS28 knockdown on BMECs. The results showed that VPS28 knockdown could decrease the mRNA expression of genes in ubiquitination-lysosome and ubiquitination- proteasome pathways, increase the mRNA expression of genes in milk fat synthesis pathway and promote triglyceride synthesis in BMECs. Our data indicate that VPS28 gene could regulate milk fat synthesis pathway; and promote triglyceride synthesis in BMECs. Our data indicate that VPS28 gene could regulate milk fat synthesis through modulating the ubiquitination-lysosome and ubiquitination-proteasome systems. Our results demonstrate the molecular mechanism of VPS28 on regulation of milk synthesis in dairy cattle through the ubiquitination signaling pathway, thereby supporting a relationship between milk fat synthesis and ubiquitination and laying the molecular foundation in breeding of dairy cattle in the future.

Abstract
Under the context of the elevated greenhouse gases, how to reduce carbon emissions and increase carbon absorption is the focus of current research on climate change. Based on data of Chinese crude steel production from 1963 to 2016 and greenhouse gas inventory method, we established steel slag carbon sequestration calculation method. The steel slag carbon sequestration from 1963 to 2016 was estimated and the uncertainty analysis was made. The results showed that annual carbon sink of steel slag in China increased from 3.75×103 t C in 1963 to 1359.32×103 t C in 2016. The steel slag accumulative carbon sink was 15×106 t C, with about ±30.4% total uncertainty during 1963-2016. The annual carbon sink of steel slag was composed of carbon sink of the current year steel slag and the previous years. Due to the dense structure and low carbonation rate of steel slag, the carbon sink of the current year was small, accounting for 37% of the total, while that of the previous years were relatively large, accounting for 63% of the total. Although annual carbon sink of steel slag was small, the long-term accumulative carbon sink for steel slag was very considerable, which could not be ignored. Future research should refine carbonation rate of steel slag under diffe-rent environmental conditions to reduce steel slag carbon accounting uncertainty, promote the deve-lopment of carbon capture and storage (CCS) technology with steel slag as raw material to increase effective carbon sequestration, which would provide scientific support for China's international negotiations on climate change.

Abstract
Objective: To investigate the relationship between body mass index (BMI) and all-cause mortality in hypertensive population. Methods: All participants were selected from a prospective cohort study based on a rural population from Henan province, China. Cox proportional hazards regression models were used to estimate the associations of different levels of BMI stratification with all-cause mortality. Restricted cubic spline models were used to detect the dose-response relation. Results: Among the 5 461 hypertensive patients, a total of 31 048.38 person-years follow-up was conducted. The median of follow-up time was 6 years, and 589 deaths occurred during the follow-up period. Compared to normal weight group (18.5 kg/m(2)<BMI<24.0 kg/m(2)) the multivariate-adjusted hazard ratios for all-cause mortality associated with BMI levels (<18.5 kg/m(2), 24-28 kg/m(2), and ≥28 kg/m(2)) were 0.83 (95%CI: 0.37-1.87), 0.81 (95%CI: 0.67-0.97), and 0.72 (95%CI: 0.56-0.91), respectively. The dose-response analysis showed a nonlinear, reverse "S" shaped relationship (non-linearity P<0.001). Conclusion: Overweight or obese might have a protective effect on all-cause mortality in hypertensive population, which supports the "obesity paradox" phenomenon.

Abstract
One of the commonly accepted merits of cohort studies (CSs) refers to the exposure precedes outcome superior to other observational designs. We use Directed Acyclic Graphs to construct a causal graph among research populations under CSs. We notice that the substitution of research population in place of a susceptible one can be used for effect estimation. Its correctness depends on the outcome-free status of the substituted population and the performance of both screening and diagnosis regarding the outcomes under study at baseline. The temporal precedence of exposure over outcome occurs theoretically, despite the opposite happens in realities. Correct effect estimate is affected by both the suitability of population substitution and the validities of outcome identification and exclusion.

Abstract
To study the curative effects and safety for patients who adopt both gefitinib and platinum-based chemotherapy or only platinum-based chemotherapy in the treatment of lung adenocarcinoma, 80 EGFR mutation-positive lung adenocarcinoma patients in stage IIIB/IV were divided into two groups. Half of them received both gefitinib and standard chemotherapy (group A), and the others (group B) received only standard chemotherapy. Overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and the related toxicities of both groups were recorded in order to take certain nursing measures for a variety of toxicities. Next, statistical methods were used to analyze the curative effects and safety of the two treatments. The results showed that ORR, DCR and median progression-free (mPFS) survival of the two groups of patients showed no statistical difference (P >0.05). However, group A (18.56 months) had a longer median overall survival (mOS) than group B (14.87 months), which was of statistical significance (P less than 0.05). Nausea and loss of appetite were common mild adverse reactions, and anemia and leukocytopenia were moderate common adverse reactions. The difference between these two groups of patients regarding adverse reactions was not statistically significant (P>0.05). In conclusion, the two treatments have similar safety, but lung adenocarcinoma patients with drug resistance during stage IIIB/IV after using first-line gefitinib therapy have lower survival benefits than patients who take both gefitinib and platinum-based chemotherapy.

Abstract
Under the background of "missing carbon sink" mystery and carbon capture and storage (CCS) technology development, this paper summarized the lime material flow process carbon sink from the lime carbonation principles, impact factors, and lime utilization categories in chemical industry, metallurgy industry, construction industry, and lime kiln ash treatment. The results showed that the lime carbonation rate coefficients were mainly impacted by materials and ambient conditions; the lime carbon sink was mainly in chemical, metallurgy, and construction industries; and current researches focused on the mechanisms and impact factors for carbonation, but their carbon sequestration calculation methods had not been proposed. Therefore, future research should focus on following aspects: to establish a complete system of lime carbon sequestration accounting method in view of material flow; to calculate lime carbon sequestration in both China and the world and explain their offset proportion of CO2emission from lime industrial process; to analyze the contribution of lime carbon sequestration to missing carbon sink for clarifying part of missing carbon sinks; to promote the development of carbon capture and storage technology and provide some scientific bases for China's international negotiations on climate change.

Abstract
Objective: To evaluate the differential calretinin immunostaining in different segments of total colonic aganglionosis and its utility in the diagnosis. Methods: Nine specimens including ileum and colon segments were obtained from 9 patients with total colonic aganglionosis (TCA), from 2010 to 2016 year, in Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science and Technology. Another 9 ganglionic specimens including the same segments from patients with non-Hirschsprung disease (non-HD) patients were collected as control. All cases were immunostained with calretinin. The patterns of calretinin immunostaining were observed, and morphometric analysis of each sample was performed by image analysis program (Image-Pro-Plus). The mean absorbance was evaluated by calculating the areas of the lamina propria occupied by the positively stained area of the calretinin at high power field. Results: The same pattern of calretinin immunostaining was seen in ganglionic ileum and ganglionic colon segments, with staining seen in intrinsic nerves fibers (INF), and in granular aggregates in the lamina propria and muscularis mucosae. There was no significant difference in the numbers of calretinin-positive INF from the ganglionic segments. In contrast, the number of calretinin-positive INF and granular aggregates in aganglionic segments were significantly lower than those in the ganglionic group (P<0.01). In the ileum transitional zone, scattered calretinin staining was observed, and the amount of calretinin-positive INF was significantly lower than those in the proximal segment of ganlionic ileum (P<0.01). Conclusions: Since there is significant different expression of calretinin among the different segments from TCA, calretinin immunostaining has potential value in detecting TCA. It could be an important adjunctive method in detecting TCA in the future.

Abstract
Objective: To analyze the quantitative expression and prognostic significance of tumor neo-vessels, macrophages and fibroblasts in tumor microenvironment of hepatocellular carcinoma (HCC). Methods: The clinic-pathological features and tissue samples for 101 HCC cases were collected. Immunohistochemistry was used to stain the tumor neo-vessels, macrophages and fibroblasts on tumor tissue. The distribution results and quantitative data of above key components were acquired by inverted microscopy equipped with CRi Nuance multispectral analysis system. The number of tumor neo-vessels and macrophages on HCC tissue were counted and the thickness of cancer stroma based on the expression of fibroblasts was measured. The clinic-pathological characteristics and overall survival were analyzed. Results: The median disease free survival (DFS) of 101 HCC cases was 5 month. The quantitative analysis of tumor neo-vessels, macrophages and fibroblasts showed that the expression range was 51-429 with median 218, 110-555 with median 259, 35.61-555.35 with median 246.98, respectively. To take the median as cutoff, all the cases could be classified into high and low expression group. The survival analysis demonstrated that the high density group of macrophages (P=0.022) and fibroblasts (P<0.001) has shorter DFS than low density group, with statistical significance. The high tumor neo-vessels group has shorter DFS with median 5 month than low density group with median 7 month. However, there was no statistical significance between these two group (P=0.197). Combined with above the three stromal components, all the cases could be classified into low, middle and high group. The survival analysis demonstrated that the high density group of stromal components has shorter DFS than the other two groups with median 3 month (P=0.001). Multivariate analysis by Cox regression indicated that cirrhosis, metastasis status, macrophages and fibroblasts density were the independent prognostic factors. Conclusion: The key elements in tumor microenvironment including tumor neo-vessels, macrophages and fibroblasts were heterogenic in HCC tissues and played significant roles in HCC invasion and metastasis.

Abstract
Angioneurotic headache is a common nerve headache featured by intermittence, repetition, paroxysm and aggravation, which can severely affect the sufferer’s quality of life. Currently, there are multiple drugs which can be used for relieving this type of headache, and the effectiveness and safety of drugs have been a subject of interest in clinical practice. To observe the effects of sibelium in combination with dibazole and offer a basis for the clinical treatment, 136 patients with angioneurotic headache who were admitted to hospital between February and September 2015 were selected and randomly divided into a test group and a control group, 68 in each. Patients in the test group were treated with sibelium in combination with dibazole, while patients in the control group were given sibelium only. The effects, adverse reactions, complications and toxic and side effects of the treatment in the two groups were observed. Furthermore, the blood flow speed and hemodynamic changes before and after treatment were compared. The results demonstrated that the hemodynamic indexes and cerebral blood flow speed of the patients in the test group showed obvious changes after treatment, and the difference was statistically significant (P<0.05); the improvement of the above indexes of the test group was superior to that of the control group, and the difference had statistical significance (P<0.05); the overall effective rate of the test group was higher than that of the control group (94.12% vs 76.47%) (P<0.05); the medication safety of the test group was higher than that of the control group (all P<0.05). It can be concluded that sibelium in combination with dibazole has a remarkable effect in treating angioneurotic headache as it can significantly improve hemodynamic indexes and cerebral blood flow speed. Moreover, the therapy seldom induces toxic and side effects, adverse reactions or complications.

Abstract
Being a low-cost, mass-production-compatible route to attain crystalline silicon, post-deposition crystallization of amorphous silicon has received intensive research interest. Here we report a low-temperature (300 °C), rapid (crystallization rate of ~17 nm/min) means of a-Si:H crystallization based on high-density hydrogen plasma. A model integrating the three processes of hydrogen insertion, etching, and diffusion, which jointly determined the hydrogenation depth of the excess hydrogen into the treated micrometer thick a-Si:H, is proposed to elucidate the hydrogenation depth evolution and the crystallization mechanism. The effective temperature deduced from the hydrogen diffusion coefficient is far beyond the substrate temperature of 300 °C, which implies additional driving forces for crystallization, i.e., the chemical annealing/plasma heating and the high plasma sheath electric field. The features of LFICP (low-frequency inductively coupled plasma) and LFICP-grown a-Si:H are also briefly discussed to reveal the underlying mechanism of rapid crystallization at low temperatures.

Abstract
Taking 39 industries as independent decision-making units in Liaoning Province from 2003 to 2012 and considering the benefits of energy, economy and environment, we combined direction distance function and radial DEA method to estimate and decompose the energy conservation and carbon emissions reduction efficiency of the industries. Carbon emission of each industry was calculated and defined as an undesirable output into the model of energy saving and carbon emission reduction efficiency. The results showed that energy saving and carbon emission reduction efficiency of industries had obvious heterogeneity in Liaoning Province. The whole energy conservation and carbon emissions reduction efficiency in each industry of Liaoning Province was not high, but it presented a rising trend. Improvements of pure technical efficiency and scale efficiency were the main measures to enhance energy saving and carbon emission reduction efficiency, especially scale efficiency improvement. In order to improve the energy saving and carbon emission reduction efficiency of each industry in Liaoning Province, we put forward that Liaoning Province should adjust industry structure, encourage the development of low carbon high benefit industries, improve scientific and technological level and adjust the industry scale reasonably, meanwhile, optimize energy structure, and develop renewable and clean energy.

Abstract
OBJECTIVE To investigate the roles of glucose regulated protein 78(GRP78) in proliferation and migration of human colorectal carcinoma cell RKO. METHODS The colorectal carcinoma cell line RKO was transfected by lentiviral vector pLV-shRNA GRP78 and lentivirus vector pLV-control. MTT test and colony formation assay were used to evaluate the cell proliferation ability. Distribution of cell cycle was analyzed by flow cytometry. Cell migration ability was detected by scratches migration experiment. In vivo tumorigenicity ability was measured using subcutaneous tumor assay. Differentially expressed genes were detected by Affymetrix human genome-wide expression profile chip and confirmed by Western blot analysis. RESULTS Compared with the negative vector transfection group, cell proliferation was inhibited in vitro and in vivo (P<0.05), while there was no significant difference in migration (P>0.05). Flow cytometry results showed that silencing GRP78 resulted in a significant increase in the proportion of cells in G1 phase, while the proportion of cells in S phase was significantly lower (P<0.05). The gene chip results showed that 397 genes were differentially expressed by at least 1.2 folds in GRP78 knocked-out RKO cells, including 258 up-regulated and 139 down-regulated ones. Bioinformatics analysis identified 3 genes (CDKN2B, MTOR and BIRC3) with specific expression in GRP78 down-regulated RKO cells, and the result was verified by Western blot. CONCLUSIONS GRP78 knock-out inhibits the proliferation and growth of colorectal cancer cell, but has no obvious effect on migration invasion. Down regulation of GRP78 results in expression changes of lots of genes in RKO cells. GRP78 may exert its role in proliferation of RKO cell through regulating these genes.

Abstract
OBJECTIVE To investigate the correlation between job burnout and salivary cortisol concentration. METHODS In September 2014, a cross-sectional survey was used to perform a questionnaire survey for 237 employees in a solar photovoltaic company. Meanwhile, saliva was collected through chewing with a tube for saliva collection, and enzyme-linked immunosorbent assay was used to measure salivary cortisol concentration. RESULTS The salivary cortisol concentration showed no significant differences between employees with different ages, working years, educational backgrounds, and shifts(P>0.05). The salivary cortisol concentration was positively correlated with the scores of emotional exhaustion, depersonalization, and job burnout(r=0.182, 0.229, and 0.222, P<0.05). The employees with emotional exhaustion, depersonalization, and job burnout had significantly higher salivary cortisol concentrations than those without emotional exhaustion, depersonalization, and job burnout(80.22±13.34 μg/L vs 75.86±14.75 μg/L, t=2.029, P<0.05; 80.69±12.99 μg/L vs 75.27±14.89 μg/L, t=2.607, P<0.05; 80.06±12.63 μg/L vs 72.76±16.04 μg/L, t=3.248, P<0.05). The stepwise regression analysis showed that salivary cortisol concentration was mainly influenced by depersonalization. CONCLUSION Job burnout is correlated with salivary cortisol concentration, and can be used as an objective assessment index for job burnout.

Abstract
OBJECTIVE To investigate the influence of occupational stress on salivary cortisol concentration in employees. METHODS In September 2014, occupational stress evaluation was performed for 186 employees in a solar photovoltaic company, and enzyme-linked immunosorbent assay was used to measure the salivary cortisol concentration. RESULTS The salivary cortisol concentration showed no significant differences between groups with different demographic features(P>0.05). The group with a high score of job control had a significantly lower salivary cortisol concentration than that with a low score(74.62±15.34 μg/L vs 79.95±12.99 μg/L, P<0.05). The groups with high scores of job danger and job responsibility and burden had significantly higher salivary cortisol concentrations than those with low scores(80.29±9.45 μg/L vs 75.60±16.41, P<0.05; 80.94±10.87 μg/L vs 74.05±16.35 μg/L, P<0.05). The salivary cortisol concentration was positively correlated with the scores of job danger and job responsibility and burden(r=0.176 and 0.252, P<0.05) and negatively correlated with the score of job control(r=-0.208, P<0.05). CONCLUSION Salivary cortisol concentration is positively correlated with occupational stress and increases with the increasing degree of occupational stress, and can be used as an objective biomarker for the identification and evaluation of occupational stress.

Abstract
OBJECTIVE To investigate the influence of job burnout on salivary immunoglobulin G(IgG) concentration in employees. METHODS In September 2014, evaluation of job burnout was performed for 186 employees in a solar photovoltaic company, and enzyme-linked immunosorbent assay was used to measure salivary IgG concentration. RESULTS The employees with over 20 working years had a significantly higher salivary IgG concentration than those with ≤15 working years(53.80±8.22 μg/ml vs 49.93±7.97 μg/ml, P<0.05). The employees with long-day shifts had a significantly higher salivary IgG concentration than those with day-night shifts (54.98±7.62 μg/ml vs 51.85±7.94 μg/ml, P<0.05). The employees with depersonalization had a significantly lower salivary IgG concentration than those without depersonalization(50.69±9.89 vs 53.19±6.54, P<0.05). The salivary IgG concentration was negatively correlated with the scores of emotional exhaustion, depersonalization, and job burnout (r=-0.194, -0.152, and -0.210, all P<0.05). CONCLUSION Job burnout is negatively correlated with salivary IgG concentration, which tends to decrease with the increasing severity of job burnout. Therefore, salivary IgG can be used as a biomarker for the identification and evaluation of job burnout.
