Abstract
PURPOSE/OBJECTIVE This study aims to understand the reciprocal relationships among acceptance of disability, attitudes toward disability, and coping among Chinese adolescents with visual impairments. RESEARCH DESIGN Adolescents with visual impairments (NT1 = 311, NT2 = 170) from four Chinese special education schools completed three questionnaires twice over 1 year. Cross-lagged panel modeling was carried out to analyze the questionnaire data. RESULTS The findings revealed that attitudes toward disability and self-directed coping at Time 1 (T1) positively predicted acceptance of disability at Time 2 (T2). Self-directed coping at T1 positively predicted attitudes toward disability at T2, and attitudes toward disability at T1 negatively predicted relinquished-control coping at T2. CONCLUSION/IMPLICATIONS Visually impaired adolescents' attitudes toward disability and coping serve as antecedents of their acceptance of disability. There is a positive reciprocal relationship between coping and attitudes toward disability. Psychological interventions aimed at optimizing psychosocial adjustment among students with visual impairments may benefit from targeting coping strategies and attitudes toward disability.

Abstract
Objectives: To examine the clinicopathological characteristics and the influencing factors of the residual tumor of patients with Breast Image Report and Data System (BI-RADS) grade 3 lesions diagnosed with malignancy after minimally invasive excision. Methods: In this retrospective case-control study, clinicopathological data of 69 cases, which had been evaluated as BI-RADS 3 lesions by ultrasound (4 151 cases) diagnosed with breast cancer by minimally invasive excision pathology, were analyzed between May 2012 and June 2016 at the Department of Breast Surgery of the Second Hospital of Shandong University and Linyi People's Hospital. All patients were female, aged (43.4±8.2) years (range: 22 to 70 years). Based on residual tumor after minimally invasive excision, patients were classified into two subgroups: tumor residual group (n=39) and non-tumor residual group (n=30). The clinicopathological features between the two groups were compared. The differences in clinicopathological characteristics were compared in different groups using the χ2 test and the t test. Potential variables identified in the univariate analysis and other relevant variables will be analyzed multivarially using Logistic regression models. The Kaplan-Meier method was applied for survival analysis and survival curves. Results: The breast cancer detection rate of ultrasound BI-RADS 3 lesions was 1.66% (69/4 151), and their maximum diameter of the masses was (1.27±0.45) cm (range: 0.5 to 2.3 cm). Among them, the maximum diameter were ≤1 cm in 28 cases and >1 cm in 41 cases. Histopathological results showed carcinoma in situ in 24 cases and invasive carcinoma in 41 cases, positive expression of the estrogen receptor in 47 cases, positive expression of the progesterone receptor in 43 cases, Ki-67 proliferation index elevated in 26 cases. Axillary metastasis positive rate was 10.1% (7/69). Residual tumor after minimally invasive surgery was found in 39 cases (56.5%). Univariate analysis showed that the tumour residual group showed a significantly increased rate of positive expression of the estrogen receptor (91.9%(34/37) vs. 61.9%(13/21), χ2=7.838, P=0.012). In multivariate analysis, the only variable found to significantly affect the residual tumor was the positive expression of the estrogen receptor (OR=16.852, 95%CI: 1.819 to 156.130, P=0.013). The 5-year disease-free survival rate of breast cancer patients with breast ultrasound BI-RADS 3 lesions was 97.1% and the overall survival rate was 98.6%. Conclusions: BI-RADS 3 lesions diagnosed by ultrasound undergoing ultrasound-guided minimally invasive excision have a certain risk of detected malignancy, approximately 1.66%. Patients with positive expression of the estrogen receptor are more likely to develop residual tumor. A secondary operation should be considered to ensure that no tumor residues remain in the cavity.

Abstract
Objective: To investigate the risk and influencing factors of long-term mortality of valvular heart disease (VHD) adults aged 35 years and over in Chinese communities. Methods: A cohort study was carried out. The data of the subjects who underwent echocardiography were collected from the Chinese Hypertension Survey between 2012 and 2015 and survival outcomes were followed up between 2018 and 2019. Kaplan-Meier survival curves were plotted and compared using log-rank test. Cox proportional hazards models were used to analyze the influence of VHD on mortality. Results: During an average follow-up time of (4.6±0.9) years, a total of 23 237 participants (10 881 males and 12 356 females) were pooled into the final analysis from 5 eastern, 5 central, and 4 western provinces, cities and autonomous regions in China, with a mean age of (56.9±13.2) years. Among the included participants, 1 004 had VHD (467 males and 537 females), with a mean age was of (68.1±12.6) years. In the Kaplan-Meier analysis, participants with VHD had a significantly increased risk of all-cause mortality (log-rank χ2=351.82, P<0.001) and cardiovascular mortality (log-rank χ2=284.14, P<0.001) compared with those without VHD. Multivariate Cox regression analysis showed that compared with those without VHD, the participants with rheumatic VHD had a 45% increased risk of all-cause mortality (HR=1.45, 95%CI: 1.12-1.89) and degenerative VHD increased the risk of cardiovascular mortality by 69% (HR=1.69, 95%CI: 1.19-2.38). The risk factors of cardiovascular mortality for VHD were age 55 years and over (55-<75 years: HR=4.93, 95%CI: 1.17-20.85;≥75 years: HR=11.92, 95%CI: 2.85-49.80) and diabetes mellitus (HR=1.71, 95%CI: 1.00-2.93). Conclusions: VHD is a risk factor of all-cause mortality and cardiovascular mortality among adults aged 35 years and over. Age 55 years and over and diabetes mellitus are adverse prognostic factors for patients with VHD.

Abstract
Aiming at the fabrication of a micro-textured surface, a novel piezoelectric-driven non-resonant elliptical vibrator is proposed in this paper; the output characteristics could be adjusted by the length change of the tool holder. The flexible mechanism is the primary structure of the vibrator, which includes a lever type mechanism, an enhanced Scott-Russell mechanism, and a T-shaped mechanism. The former two mechanisms are used to enlarge the output of the piezoelectric actuator, and the T-shaped mechanism is applied to transfer the parallel movements to the elliptical trajectory. The theoretical models including the elliptical trajectory, output stiffness, and resonant frequencies are established to investigate the impacts of the tool holder and controlling signals on the output characteristics of the vibrator, which are further validated using the finite element analysis method. A prototype is developed by integrating the non-resonant elliptical vibrator assembly and controlling system. Some experiments are carried out to verify the basic performance and the adjustable properties of the vibrator.

Abstract
Objective: To explore the risk factors of malnutrition in infants with congenital heart disease within one year after surgery. Methods: This retrospective cohort study selected 502 infants with congenital heart disease who underwent surgical treatment in Guangzhou Women and Children's Medical Center from February 2018 to January 2019. Their basic information and clinical data were analyzed, and their nutrition status after the surgery was followed up by questionnaire survey. Weight-for-age Z score (WAZ)≤-2 one year after operation was defined as malnutrition group, and WAZ>-2 was non-malnutrition group. The perioperative indicators and complementary food advancement were compared between the two groups by chi-square test, t-test, and Kruskal-Wallis test. The risk factors of malnutrition were analyzed by Logistic regression. Results: A total of 502 infants were selected, including 301 males and 201 females, with the age of 4.1 (2.0, 6.8) months. There were 90 cases in malnutrition group and 412 cases in non-malnutrition group. The body length and weight at birth in the malnutrition group were lower than those in the non-malnutrition group ((47.8±3.8) vs. (49.3±2.5) cm, (2.7±0.6) vs.(3.0±0.5) kg, both P<0.001). The proportion of paternal high school education or above and the proportion of family per capita income of 5 000 yuan or above in the malnutrition group were lower than those in the non-malnutrition group ((18.9% (17/90) vs. 30.8% (127/412), 18.9% (17/90) vs. 33.7% (139/412), both P<0.05). Compared to the non-malnutrition group, the proportion of complex congenital heart disease in the malnutrition group was higher (62.2% (56/90) vs. 47.3% (195/412), P<0.05). The postoperative mechanical ventilation time, postoperative intensive care unit (ICU) stay time, postoperative hospital stay, total length of ICU stay and total hospital stay in the malnutrition group were significantly longer than those in non-malnutrition group (all P<0.05). The proportion of egg and fish supplementation over 2 times/week within one year after the surgery was also lower in the malnutrition group (both P<0.05). Logistic regression analysis showed that mother's weight at delivery (OR=0.95,95%CI 0.91-0.99), the pre-operative WAZ≤-2 (OR=6.04, 95%CI 3.13-11.65), the complexity of the cardiac disease (OR=2.23, 95%CI 1.22-4.06), the hospital stay after the surgery over 14 days (OR=2.61, 95%CI 1.30-5.26), the types of complementary food<4 (OR=2.57, 95%CI 1.39-4.76), and the frequency of meat and fish<2 times/week (OR=2.11, 95%CI 1.13-3.93) were the risk factors associated with malnutrition within one year after the surgery. Conclusion: Mother's weight at delivery pre-operative nutritional status, complexity of cardiac disease, postoperative hospital stay, types of daily supplements and frequency of fish are risk factors associated with malnutrition within one year after surgery in children with congenital heart disease.

Abstract
Objective: To investigate the prevalence of albuminuria in Chinese residents aged >35 years and its potential association with cardiovascular disease (CVD). Methods: A total of 34 647 Chinese subjects aged ≥35 years were selected by stratified multi-stage random sampling from 2012 to 2015. Data were collected through questionnaires, physical examinations, and laboratory tests. Albuminuria was categorized into 3 types according to urinary albumin-to- creatinine ratio: normal (<30 mg/g), microalbuminuria (MAU, 30-300 mg/g), and macroalbuminuria (≥300 mg/g). Measurement data were expressed as x¯±s, and t-tests were used for comparisons between indicators. Qualitative data were expressed as rate or constituent ratio, and the χ2 test or Kruskal-Wallis test was used to examine differences. Logistic regression was used for multivariate analyses. SAS 9.4 software was used for statistical analyses, and P<0.05 was considered statistically significant. Results: The prevalence of abnormal albuminuria was 19.1%; the prevalence was 17.2% for MAU and lower in males (13.8%) than females (20.1%, P<0.01). The risk of CVD was higher among subjects with MAU (OR=1.23, 95%CI 1.12-1.35) and macroalbuminuria (OR=1.86, 95%CI 1.50-2.32). When MAU was complicated by hypertension and diabetes mellitus, the CVD risk was 1.76 times higher. Conclusions: The prevalence of MAU is high among Chinese subjects aged 35 years and over. Those with MAU have higher CVD risk, especially those with hypertension and diabetes mellitus.

Abstract
Objective: To describe fertility and explore factors associated with it among pre-conception couples of childbearing age. Methods: Based on the pre-conceptional offspring trajectory study of the School of Public Health of Fudan University, couples of childbearing age who participated in the pre-conception physical examination in Shanghai Jiading District from 2016 to 2021 were recruited and followed up. Couples' time to pregnancy (TTP) was analyzed and Cox proportional hazards regression model was used to explore the factors associated with TTP. Kaplan-Meier was used to calculate each menstrual cycle's cumulative pregnancy rate. Results: A total of 1 095 preconception couples were included in the analysis, the M(Q1,Q3)of TTP was 4.33 (2.41, 9.78) menstrual cycles. Age of women (FR=0.90, 95%CI: 0.85-0.95, P<0.001), women who were overweight or obese before pregnancy (FR=0.36, 95%CI: 0.24-0.55, P<0.001), women who were exposed to second-hand smoking (FR=0.63, 95%CI: 0.44-0.92, P=0.016), women whose home or office had been renovated in the past 2 years and had a particular smell (FR=0.46, 95%CI: 0.26-0.81, P=0.008) were risk factors for impaired fertility. Regular menstrual cycles (FR=1.64, 95%CI: 1.16-2.31, P=0.005), females who often drank tea/coffee (FR=1.55, 95%CI: 1.11-2.17, P=0.011) and males who took folic acid before conception (FR=2.35, 95%CI: 1.38-4.23, P=0.002) were associated with better fertility. The cumulative pregnancy rate of 3, 6, and 12 menstrual cycles was 37.6%, 64.4%, and 78.4%, respectively. Conclusion: Older couples, overweight or obesity before pregnancy, irregular menstruation, exposure to secondhand smoke and decoration pollutants in females are associated with impaired fertility. Frequent tea/coffee drinking before pregnancy in females and taking folic acid before pregnancy in males are associated with shortened conception time.

Abstract
Objective: To estimate the prevalence, awareness, treatment and control rate of hypertension among young and middle-aged population in China. Methods: The analysis was based on the results of 2012-2015 China Hypertension Survey, which was a cross-sectional stratified multistage random sampling survey. A total of 229 593 subjects were included in the final analysis. The data including sex, age, living in urban and rural areas, prevalence of hypertension, history of stroke, family history of coronary heart disease and drinking, physical examination, heart rate were collected. Hypertension was defined as mean systolic blood pressure (SBP) ≥140 mmHg (1 mmHg=0.133 kPa), and (or) diastolic blood pressure (DBP) ≥90 mmHg, and (or) self-report a history of hypertension, and (or) use of antihypertensive medicine within 2 weeks before survey. Prehypertension was defined as SBP between 120-139 mmHg, and (or) DBP between 80-89 mmHg. Control of hypertension was considered for hypertensive individuals with SBP<140 mmHg and DBP<90 mmHg. The prevalence of prehypertension, hypertension, awareness, treatment, control rate were calculated, and the control rate among those with antihypertensive medication was also calculated. Results: The prevalence of prehypertension and hypertension was 43.8% (95%CI: 42.3%-45.4%), and 22.1% (95%CI: 20.8%-23.3%), respectively. The prevalence of prehypertension and hypertension was significantly higher among male than female across different age groups. The awareness, treatment, control rate of hypertension and control rate among treated hypertensive participants were 43.8%, 33.2%, 16.7%, and 40.2%, respectively. The prevalence was higher, and the control rate was lower among individuals with higher heart rate. Conclusion: The prevalence of prehypertension and hypertension among young and middle-aged population is high, the awareness, treatment and control rate need to be further improved in this population. The prevention and treatment of hypertension should be strengthened in the future to improve the control rate of hypertension in China.

Abstract
Objective: To provide evidence for optimizing the screening strategy for gastric cancer (GC), we evaluated the risk of incident GC for individuals with different precancerous gastric lesions in a prospective cohort study. Methods: Based on the National Upper Gastrointestinal Cancer Early Detection Program launched in Linqu, Shandong, a high-risk area of gastric cancer in China, we included a total of 14 087 subjects diagnosed with different gastric lesions stages by endoscopic screening from 2012 to 2018. Study subjects were prospectively followed up until December 31, 2019. The incidence of GC during the follow-up was ascertained by repeated endoscopic examinations, cancer, death registry reports, and active follow-up of study subjects and was confirmed by reviewing medical records extracted from the hospital information management system. The Poisson regression model was applied to calculate the relative risk (RR) and 95%CI for GC occurrence among subjects with different gastric lesions. Results: Among 14 087 subjects with different gastric lesions as determined by their first endoscopic examination in 2012-2018, 7 608 (54.00%) had a global diagnosis of superficial gastritis (SG), 2 848 (20.22%) had chronic atrophic gastritis (CAG), 3 103 (22.03%) had intestinal metaplasia (IM), and 520 (3.69%) had low-grade intestinal neoplasia (LGIN). During the follow-up, 109 subjects were diagnosed with GC, including 63 with high-grade intestinal neoplasia (HGIN) and 46 with invasive GC. Compared to subjects having normal gastric mucosa or SG, those with CAG (RR=3.85, 95%CI: 2.04-7.28), IM (RR=5.18, 95%CI: 2.79-9.60), and LGIN (RR=19.08, 95%CI: 9.97-36.53) had significantly increased risk of progression to GC. Individuals with these gastric lesions had an elevated risk of developing HGIN and invasive GC. For subjects with LGIN, the RR was 22.96 (95%CI: 9.71-54.27) for developing HGIN and 14.64 (95%CI: 5.37-39.93) for developing invasive GC. Subgroup analyses found that all age group subjects with LGIN diagnosed during the initial endoscopic examination had a significantly increased risk of developing the GC. Conclusions: Our large-scale prospective study on a high-risk area of GC showed that most residents aged 40-69 years had gastric lesions of different stages. Subjects with more advanced gastric lesions had a significantly increased risk of progression to GC.

Abstract
BACKGROUND As three key indicators of psychosocial adaptation, coping, self-esteem, and social integration are vital for students with visual impairments. AIMS This study aimed to examine the reciprocal relationships among visually impaired students' coping, self-esteem, and social integration. METHODS Students with visual impairments (NTime1 = 311, NTime2 = 170) from four special schools in mainland China responded to three inventories at two timepoints over one year. Cross-lagged panel modelling was performed to analyse the data. RESULTS After controlling for gender, self-esteem positively predicted self-directed coping and negatively predicted relinquished-control coping. An inverse path was found in the prediction of relinquished-control coping to self-esteem. Social integration positively predicted self-esteem. Furthermore, gender did not moderate the relationships in the cross-lagged model. CONCLUSIONS AND IMPLICATIONS Evidence is provided for a negative loop between self-esteem and relinquished-control coping. Social integration could be a precursor of self-esteem, and self-esteem could be a precursor of self-directed coping. Moreover, the study has practical implications for special schools, teachers, parents, and students on enhancing visually impaired students' psychosocial adaptation.

Abstract
Objective: To investigate the clinical features and influencing factors of long-term prognosis of tuberculous meningitis(TBM), and to provide a recommendation for treatment and early intervention of TBM. Methods: Clinical data of TBM patients were retrospectively collected at Peking Union Medical College Hospital from January 2014 to December 2021. Patients who were followed-up more than one year were divided into two groups according to modified Rankin Scale (mRS). Risk factors associated with long-term prognosis were analyze by conditional logistic stepwise regression. Results: A total of 60 subjects were enrolled including 33 (55%) males and 27 (45%) females with age 15-79 (44.5±19.8) years. There were 30 cases (50%) complicated with encephalitis, 21 cases (35%) with miliary tuberculosis. The diagnosis was microbiologically confirmed in 22 patients (36.7%), including 5 cases (22.7%, 5/22) by acid-fast staining, 8 cases (36.4%, 8/22) by Mycobacterium tuberculosis (MTB) culture, and 20 cases (90.9%, 20/22) by molecular biology. The median follow-up period was 52(43, 66 ) months in 55 cases surviving more than one year. Among them, 40 cases (72.7%) were in favorable group (mRS 0-2) and 15 cases (27.3%) were in unfavorable group (mRS 3-6) with poor prognosis. The mortality rate was 20% (11/55). Elderly (OR=1.06, P=0.048 ) , hyponatremia(OR=0.81,P=0.020), high protein level in cerebrospinal fluid (CSF) (OR=3.32,P=0.033), cerebral infarction(OR=10.50,P=0.040) and hydrocephalus(OR=8.51,P=0.049) were associated with poor prognosis in TBM patients. Conclusions: The mortality rate is high in patients with TBM. Molecular biology tests improves the sensitivity and shorten the diagnosis time of TBM. Elderly, hyponatremia, high protein level in CSF, cerebral infarction and hydrocephalus are independent risk factors of long-term survival in TBM patients.

Abstract
BACKGROUND Anti-N-methyl-D-aspartate receptor encephalitis (NMDARe) is capable of presenting a relapsing course and coexisting with myelin oligodendrocyte glycoprotein antibody disease, whereas it has been relatively rare. We describe a man with no history of tumor who successively developed anti-NMDARe and anti-myelin oligodendrocyte glycoprotein antibody disease.
CASE SUMMARY A 29-year-old man was initially admitted with headache, fever, intermittent abnormal behavior, decreased intelligence, limb twitching and loss of consciousness on July 16, 2018. On admission, examination reported no abnormality. During his presentation, he experienced aggravated symptoms, and the re-examination of cranial magnetic resonance imaging (MRI) indicated punctate abnormal signals in the left parietal lobe. External examination of cerebrospinal fluid and serum results revealed serum NMDAR antibody (Ab) (-), cerebrospinal fluid NMDAR-Ab (+) 1:10 and Epstein-Barr virus capsid antigen antibody IgG (+). Due to the imaging findings, anti-NMDARe was our primary consideration. The patient was treated with methylprednisolone and gamma globulin pulse therapy, mannitol injection dehydration to reduce intracranial pressure, sodium valproate sustained-release tablets for anti-epilepsy and olanzapine and risperidone to mitigate psychiatric symptoms. The patient was admitted to the hospital for the second time for “abnormal mental behavior and increased limb movements” on December 14, 2018. Re-examination of electroencephalography and cranial MRI showed no abnormality. The results of autoimmune encephalitis antibody revealed that serum NMDAR-Ab was weakly positive and cerebrospinal fluid NMDAR-Ab was positive. Considering comprehensive recurrent anti-NMDARe, the patient was treated with propylene-hormone pulse combined with immunosuppressive agents (mycophenolate mofetil), and the symptoms were relieved. The patient was admitted for “hoarseness and double vision” for the third time on August 23, 2019. Re-examination of cranial MRI showed abnormal signals in the medulla oblongata and right frontal lobe, and synoptophore examination indicated concomitant esotropia. The patient’s visual acuity further decreased, and the re-examination of cranial MRI + enhancement reported multiple scattered speckled and patchy abnormal signals in the medulla oblongata, left pons arm, left cerebellum and right midbrain, thalamus. The patient was diagnosed with an accompanying demyelinating disease. Serum anti-myelin oligodendrocyte glycoprotein 1:10 and NMDAR antibody 1:10 were both positive. The patient was diagnosed with myelin oligodendrocyte glycoprotein antibody-related inflammatory demyelinating disease of the central nervous system complicated with anti-NMDARe overlap syndrome. The patient was successfully treated with methylprednisolone, gamma globulin pulse therapy and rituximab treatment. The patient remained asymptomatic and follow-up MRI scan 6 mo later showed complete removal of the lesion.
CONCLUSION We emphasize the rarity of this antibody combination and suggest that these patients may require longer follow-up due to the risk of recurrence of two autoimmune disorders.

Abstract
Objective: To investigate the prevalence, awareness, treatment and control status of dyslipidemia among females aged ≥35 years old across China. Methods: Participants were selected by stratified multistage random sampling method in the "Twelfth Five-Year Plan" National Science and Technology Support Project "Survey on the Prevalence of Important Cardiovascular Diseases and Key Technology Research in China" project. This study is a retrospective, cross-sectional study. A total of 17 418 females aged 35 years and over were included in the current study. The basic information such as age, medical history and menopause was collected by questionnaire. The blood lipid parameters were derived from clinical laboratory examinations. The prevalence of dyslipidemia and the rate of awareness, treatment, and control of dyslipidemia were analyzed in females aged 35 years and over. Results: The age of participants was (56.2±13.0) years old, and the prevalence of dyslipidemia was 33.1% (5 765/17 418). The prevalence rates of high total cholesterol, hypertriglyceridemia, low HDL-C and high LDL-C were 9.7% (1 695/17 418), 11.1% (1 925/17 418), 10.9% (1 889/17 418) and 7.3% (1 262/17 418), respectively. The prevalence of dyslipidemia increased with age and the prevalence of dyslipidemia in women who were not married, Han, menarche age>16 years, obesity, central obesity, alcohol consumption, diabetes, hypertension and family history of cardiovascular disease were higher than those without such characteristics (P<0.05). There were 10 432 (59.9%) menopausal females in this cohort and prevalence of dyslipidemia of these participants was 38.8% (4 048/10 432), which was higher than that of non-postmenopausal females (24.6%, 1 717/6 986) (P<0.05). The awareness rates, treatment rates and control rates of dyslipidemia were 33.9% (1 953/5 765), 15.1% (870/5 765) and 2.5% (143/5 765) respectively among females aged 35 years and over in China. Conclusion: The prevalence of dyslipidemia in Chinese females aged 35 years and over is high, and its awareness, treatment, and control rates need to be optimized.

Abstract
Objective: To evaluate the preliminary efficacy and safety of ab interno canaloplasty (ABiC) combined with micro-incision cataract surgery for treating primary open angle glaucoma (POAG) combined with cataract. Methods: Prospective case series study. Patients diagnosed with POAG and concurrent cataract were enrolled to receive ABiC combined with micro-incision phacoemulsification and intraocular lens implantation in the Eye Center of the Second Affiliated Hospital of Zhejiang University School of Medicine from June 2018 to October 2019. Intraocular pressure (IOP), use of hypotensive medications, visual acuity, visual field, and optic nerve at baseline as well as at 1 day, 1 week, 1 month, 3 months, 6 months, and 12 months postoperatively were assessed. Subgroup analyses were further performed to evaluate these data between controlled and uncontrolled POAG, as well as among mild, moderate, and advanced POAG. Success rate and complications were analyzed. Results: A total of 68 eyes in 42 patients completed a follow-up of 12 months. Compared to the baseline IOP under medical control [(18.25±2.65) mmHg (1 mmHg=0.133 kPa)], the mean postoperative IOP at 1 month [(14.31±3.25) mmHg], 3 months [(14.00±3.09) mmHg], 6 months[ (14.58±2.93) mmHg], and 12 months[ (14.84±2.73) mmHg] was all significantly reduced (P<0.05). The median (upper quadrant, lower quadrant) of the hypotensive medication number was 2.5 (2, 3) at baseline, which was significantly reduced to 0 (0, 1) at 1 month, and 0 (0, 0) at 3, 6, and 12 months (P<0.05). The complete success rate and qualified success rate at 12 months were 80.88%(55/68) and 89.71%(61/68), respectively. No deterioration in the visual field or optical coherence tomography scan of the optic nerve was observed at 12 months compared to the baseline status. Hyphema (26 eyes, 38.24%) and transient IOP spike (23 eyes, 33.82%) were the most common complications, but no severe case was present. Conclusion: ABiC combined with micro-incision cataract surgery is considerably effective and safe in the treatment of POAG combined with cataract in the Chinese population.

Abstract
Objective: To explore the effect of emotional optimization of workplace employees in immersive virtual natural environment. Methods: In July 2020, 15 subjects were selected to complete two groups of treadmill walking training experiments in virtual natural environment and daily environment respectively. At the same time, the subjects' skin electrical (EDA) , pulse frequency (Pf) , respiratory frequency (Rf) physiological data and Self-Assessment Manikin (SAM) data before and after walking were collected; the mean value of three dimensions of SAM and the emotion difference before and after the experiment were calculated. The differences of physiological indexes and subjective mood changes of subjects were tested by paired sample t-test. Results: Compared with the daily environment, the ΔEDA, ΔPf and ΔRf of the subjects in the virtual natural environment were all decreased , and the differences were statistically significant (P<0.05). There were statistically significant differences in pleasure and arousal between subjects before and after using the virtual natural environment (P <0.05). Compared with the daily environment, the Δpleasure degree of subjects using the virtual natural environment increased, and the Δarousal degree and Δdominance degree decreased, and the differences were statistically significant (P <0.05). Conclusion: Walking in virtual natural environment can help subjects improve their mood, relax and improve the regulation ability of autonomic nervous system.

Abstract
Aluminum is one of the most abundant elements on earth. Aluminum compounds are widely used in food additives, antacids, cooking utensils and so on. Human exposure to aluminum is mainly through diet and drinking water, while excessive intake of aluminum can accumulate in tissues and cause toxic reactions. In the central nervous system, aluminum exposure is closely related to a series of nervous system diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis. Epigenetic modification refers to the regulation of gene expression without changing the DNA sequence, and its regulatory disorders can lead to abnormalities and diseases of the central nervous system. This paper describes the regulation of epigenetics and its components, including DNA methylation, histone modification and non-coding RNA, in aluminum-induced neurotoxicity, in order to provide insights into the epigenetic mechanism of aluminum-induced neurotoxicity.

Abstract
Exposures to multiple air pollutants during pregnancy have been associated with the risk of gestational diabetes mellitus (GDM). However, their combined effects are unclear. We aimed to evaluate the combined associations of five air pollutants from pre-pregnancy to the 2nd trimester with GDM. This study included 20,113 participants from the Born in Guangzhou Cohort Study (BIGCS). The inverse distance-weighted models were used to estimate individual air pollutant exposure, namely ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter less than 10 μm in diameter (PM10), and less than 2.5 μm in diameter (PM2.5). We estimated stage-specific associations of air pollutants with GDM using generalized estimating equation, and departures from additive joint effects were assessed using the relative excess risk (RERI) and the joint relative risk (JRR). Of the 20,113 participants, 3440 women (17.1%) were diagnosed with GDM. In the adjusted model, increased concentrations of O3 and SO2 3-6 months before pregnancy were associated with GDM occurrence, as well as O3 and PM10 in the 1st trimester, the adjusted relative risk (95% confident intervals) [RRs (95%CI)] ranged from 1.05 (1.00, 1.09) to 1.21 (1.04, 1.40). The largest JRR for GDM was the combination of SO2, NO2, and PM10 in the 1st trimester (JRR = 1.32, 95% CI: 1.10, 1.59). The JRR for O3 and SO2 was less than their additive joint effects [RERI = -0.25 (-0.47, -0.04), P for interaction = 0.048]. Associations of air pollutants with GDM differed somewhat by pre-pregnancy BMI and season. This study added new evidence to the current understanding of the combined effects of multiple air pollutants on GDM. Public health strategies were needed to reduce the adverse effects of air pollution exposure on pregnant women.

Abstract
To investigate the association between infancy weight gain and neurodevelopment among term-born infants. Singleton term-born infants (n = 5837) were included from the Born in Guangzhou Cohort Study. Absolute weight gain was obtained by calculating the weight difference from birth to exactly 12 months. The primary outcome was neurodevelopment at age one year, which included five developmental domains. Global developmental delay was defined as delays in ≥3 domains. Multivariable logistic regression was used to examine the associations between infancy weight gain and neurodevelopment. Compared with infants gaining 6001-7000 g (reference group), infants gaining ≤5000 g had higher odds of delay in adaptive, gross motor, fine motor, social, and global developmental delay, infants gaining 5001-6000 g had higher odds of gross motor delay and social delay. A sex-stratified analysis showed that compared with the reference group, gaining ≤5000 g was associated with higher odds of fine motor delay in male infants, while gaining >7000 g was associated with higher odds of fine motor delay in females. Inadequate infancy weight gain is associated with higher odds of poor neurodevelopment at age one year among term-born infants.

Abstract
Traditionally, it had been commonly believed that individuals in the same culture have personalities distinct from those of individuals in other cultures. This article examines this belief by critically reviewing relevant literature generated from two of the most widely investigated personality-based style constructs in the field of intellectual styles: the Jungian personality styles and the career personality styles proposed by Holland. It aims at answering the question of whether personality-based intellectual styles are culture specific or they are universal. To achieve this aim, based on the two broad cultural systems derived from Hofstede's model of four cultural dimensions and two major style types from Zhang and Sternberg's threefold model of intellectual styles, two research hypotheses were made. To test the hypotheses, two types of empirical literature centered on each of the two personality-based styles are reviewed: (1) cross-cultural comparative studies; and (2) within-culture studies investigating the association of the two style constructs with other human attributes and outcomes. Results suggest that although personality-based styles are related to culture, they cannot be culture specific; rather, they are fundamentally universal. These findings carry scientific value and have practical implications for education and beyond.

Abstract
OBJECTIVES Corynebacterium glutamicum (C. glutamicum) has been harnessed for multi-million-ton scale production of glutamate and lysine. To further increase its amino acid production for fermentation industry, there is an acute need to develop next-generation genome manipulation tool for its metabolic engineering. All reported methods for genome editing triggered with CRISPR-Cas are based on the homologous recombination. While, it requires the generation of DNA repair template, which is a bottle-neck for its extensive application. RESULTS In this study, we developed a method for gene knockout in C. glutamicum via CRISPR-Cpf1-coupled non-homologous end-joining (CC-NHEJ). Specifically, CRISPR-Cpf1 introduced double-strand breaks in the genome of C. glutamicum, which was further repaired by ectopically expressed two NHEJ key proteins (Mycobacterium tuberculosis Ku and ligase D). We provide the proof of concept, for CC-NHEJ, by the successful knockout of the crtYf/e gene in C. glutamicum with the efficiency of 22.00 ± 5.56%, or something like that. CONCLUSION The present study reported a novel genome manipulation method for C. glutamicum.

Abstract
Objective: To translate and revise the Karitane Parenting Confidence Scale (KPCS),which can be used to evaluate the parenting confidence of 0-12 months infant caregivers in China, and evaluate the reliability and validity test of Chinese version of KPCS. Methods: Form a Chinese version of Karitane Parenting Confidence Scale through translation, back translation and expert review. Mothers of 3-month-old infants were recruited from two Maternal and Child Health Hospitals in Beijing and Ma'anshan in April 2019. A total of 165 mothers responded the survey invitations. They were surveyed with self-administered questionnaires, the Chinese version of KPCS, the Parenting Sense of Competence Scale (PSOC) and Self-efficacy in Infant Care Scale (SICS). Item analysis was conducted to select items by using critical value and correlation coefficient. The construct validity was assessed by exploratory factor analysis, confirmatory factor analysis. The criterion validity was assessed by being compared with PSOC and SICS. The reliability analysis was assessed by Cronbach's α the split-half reliability coefficient and rest-retest reliability coefficient. Results: The scores of 15 items were all correlated with the total score of the Chinese version of KPCS with r ranging from -0.283 to 0.643 (P<0.001). The difference of critical values of all items of KPCS among the low and high score groups were statistically significant (P<0.001). Three factors labeled parenting, support, and sense of competence, were obtained by exploratory factor analysis which accounting for 49.52% of the total variance and the factor loading values of all items are more than 0.4. The confirmatory factor analysis confirmed the hypothesized three-factor structure. The total score of KPCS was significantly correlated with the total score of PSOC and SICS(r=0.381, 0.345, P<0.001). The Cronbach's α of the Chinese version of KPCS was 0.769, and each dimension of Cronbach's α were 0.332-0.800, the test-retest reliability coefficient was 0.817, and the split-half reliability coefficient was 0.789. Conclusion: The Chinese version of the Karitane parenting confidence scale has a good reliability and validity among the 0-12 month-old infants' mothers, which can be used to evaluate the parenting confidence of infant caregivers.

Abstract
To investigate the effects of long-term fertilization on the accumulation and availability of heavy metals in reddish paddy soil and to analyze the major influencing factors, soil samples were collected after the later rice was harvested in 2018 from a long-term fertilization field experiment that began in 1984. Six treatments were selected, namely CK (control without fertilization), PK (P and K fertilizer), and NPK (N, P, and K fertilizer), and different proportions of organic fertilizer plus chemical fertilizer (M1NPK: 30%M+70%NPK; M2NPK: 50%M+50%NPK; and M3NPK: 70%M+30%NPK), soil chemical properties, total and available heavy metal contents, and the relationships between the available forms of heavy metals and soil chemical parameters and total heavy metals (THM) were analyzed. The results showed that ① long-term fertilization changed the soil chemical properties; compared with those of CK, PK significantly increased the contents of soil available phosphorus (AP) and available potassium (AK), NPK significantly increased the soil organic matter (SOM), cation exchange capacity (CEC), AP, and AK, and the organic fertilizer treatments significantly increased the contents of SOM, CEC, AP, AK, and nitrate (NO3--N). ② There were slight variations in the THM contents under the chemical fertilizer treatments (PK and NPK), whereas the organic fertilizer treatments significantly increased the total contents of Cu, Zn, and Cd. ③ The chemical fertilizer treatments significantly increased the available Cr and As, whereas the organic fertilizer treatments significantly increased the available Cu, Zn, Cr, Cd, As, and Fe. ④ There were significant positive correlations between the available Cu, Zn, Cr, Cd, As, and Fe and the SOM, CEC, AP, and NO3--N. In addition, the available Zn and Cd were significantly positively correlated with the soil pH, whereas the available Pb was significantly negatively correlated with soil pH, SOM, CEC, and NO3--N. ⑤ There were significant positive correlations between the available and total contents of Cu, Zn, and Cd, whereas there were significant negative correlations between the available and total contents of Cr and Fe. ⑥ Redundancy analysis showed that SOM and pH accounted for 80.7% and 5.5% of the variation in THM, whereas the soil CEC, AP, and pH accounted for 81.1%, 4.9%, and 3.3% of the variation in the available heavy metals, respectively. ⑦ The partial least squares path model analysis showed that the path coefficients of the THM, CEC, and AP on the available state of heavy metals were 0.459, 0.417, and 0.293, respectively. Long-term application of organic manure, such as pig manure, significantly improved the soil chemical properties and affected the availability of heavy metals, and soil CEC and AP may play key roles in regulation.

Abstract
BACKGROUND The undergraduate program of psychiatry has been widely established in recent years to improve the education and recruitment of psychiatrists in China. We aim to investigate the career choice of medical students majoring in psychiatry in China and the influential factors. METHOD This multicenter study was conducted in 26 medical schools in China from May to October of 2019. Participants included 4610 medical students majoring in psychiatry and 3857 medical students majoring in clinical medicine. Multivariable logistic regression was used to investigate the influential factors of students' choices of psychiatry at matriculation and as a career. RESULTS 44.08% of psychiatry majored students gave psychiatry as a first choice at matriculation, and 56.67% of them would choose psychiatry as a career, which was in sharp contrast to the proportion of clinical medicine majored students who would choose psychiatry as a career (0.69%). Personal interest (59.61%), suggestions from family members (27.96%), and experiencing mental problems (23.19%) were main reasons for choosing psychiatry major at matriculation. Personal interest (odds ratio [OR] = 2.12, 95% confidence interval [CI] = 1.87-2.40), experiencing a psychiatry clerkship (OR = 1.99, 95% CI = 1.28-3.08), being female (OR = 1.50, 95% CI = 1.30-1.68), experiencing mental problems (OR = 1.33, 95% CI = 1.28-1.56), and suggestions from family members (OR = 1.25, 95% CI = 1.08-1.46) correlated positively with students' choice of psychiatry as career. Students who lacked psychiatry knowledge (OR = 0.49, 95% CI = 0.29-0.85) or chose psychiatry because of lower admission scores (OR = 0.80, 95% CI = 0.63-0.97) were less likely to choose psychiatry as a career. CONCLUSION More than half of psychiatry majored medical school students planned to choose psychiatry as their career, whereas very few students in the clinic medicine major would make this choice. Increasing students' interest in psychiatry, strengthening psychiatry clerkships, and popularizing psychiatric knowledge are modifiable factors to increase the psychiatry career intention. The extent to which medical students' attitudes toward psychiatry can be changed through medical school education and greater exposure to psychiatry will need further investigation.

Abstract
OBJECTIVE To examine the relationship between serum vitamin D level and immune imbalance in advanced schistosomiasis patients with liver fibrosis. METHODS A total of 120 advanced schistosomiasis patients with liver fibrosis that were admitted to the Department of Schistosomiasis of The First Hospital of Jiaxing City from May 2016 to September 2018 were recruited as the observation group, and 50 healthy volunteers randomly sampled from the hospital during the same period served as the control group. The serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ cell proportion, CD8+ cell proportion, 25-hydroxyvitamin D [25(OH)D] levels were compared between the two groups. Liver fibrosis was classified into grade I, II and III according to the classification criteria of liver fibrosis by ultrasonography, and the serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ proportion, CD8+ proportion, 25(OH)D levels were compared among patients with grade I, II and III liver fibrosis. In addition, all patients were classified into the sufficient group, the insufficient group and the deficient group according to the serum vitamin D level, and the serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ proportion, CD8+ proportion, 25(OH)D levels were compared among these three groups. Moreover, the associations of the serum vitamin D level with these immune indicators were examined. RESULTS The 120 advanced schistosomiasis patients with liver fibrosis included 58 men and 62 women, and had a mean age of (72.00 ± 3.00) years. There were 32 cases with grade I liver fibrosis, 46 cases with grade II liver fibrosis, and 42 cases with grade III liver fibrosis. There were no significant differences between the observation group and the control group in terms of serum D-dimer, total cholesterol (TC), triglyceride (TG), C3 complement or C4 complement levels (t = 2.467, 0.322, 0.790, -2.432 and -2.630, all P values > 0.05); however, there were significant differences seen in alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood calcium, blood phosphorus, IgG antibody, IgA antibody, CD4+ proportion, CD8+ proportion, and 25(OH)D levels (t = 5.130, 6.382, -1.341, 2.361, 8.708, 11.783, -2.995, -6.543 and -3.022, all P values < 0.05). In addition, there were significant differences in AST, ALT, blood phosphorus, IgA antibody, C3 complement, CD8+ cell proportion and 25(OH)D levels among patients with grades I, II and III liver fibrosis (F = 19.704, 16.254, 62.669, 49.347, 5.430, 5.434 and 5.783, all P values < 0.05). There were significant differences in ALT, blood phosphorus, IgA antibody, CD8+ cell proportion and 25(OH)D levels between patients with grades I and III liver fibrosis (all P values < 0.05), and significant differences were seen between patients with grades II and III liver fibrosis in terms of blood phosphorus, IgA antibody and CD8+ cell proportion (all P values < 0.05), while there was a significant difference in the CD8+ cell proportion between patients with grades I and II liver fibrosis (P < 0.05). Moreover, there were significant differences among the sufficient, insufficient and deficient groups in terms of IgG antibody, IgA antibody, C3 complement, CD4+ cell proportion and CD8+ cell proportion (F = 13.303, 59.623, 8.698, 9.969 and 12.805, all P values < 0.05), and there was a significant difference in the CD8+ cell proportion between the insufficient and deficient groups (P < 0.05). Pearson correlation analysis revealed that serum 25(OH)D level were negatively associated with IgG and IgA antibody levels (r = -0.754 and -0.773, both P values < 0.05), and positively associated with C3 complement, CD4+ cell proportion and CD8+ cell proportion in advanced schistosomiasis patients with liver fibrosis (r = 0.827, 0.850 and 0.830, all P values < 0.05). CONCLUSIONS Immune imbalance occurs in advanced schistosomiasis patients with liver fibrosis, and serum vitamin D level may correlate with immune imbalance in advanced schistosomiasis patients with liver fibrosis.

Abstract
BACKGROUND The exploitation of novel alleles from wild rice that were lost during rice cultivation could be very important for rice breeding and evolutionary studies. Plant height (PH) was a target of artificial selection during rice domestication and is still a target of modern breeding. The "green revolution" gene semi-dwarf 1 (SD1) were well documented and used in the past decades, allele from wild rice could provide new insights into the functions and evolution of this gene. RESULTS We identified a PH-related quantitative trait locus, qCL1.2,from wild riceusing a set of chromosome segment substitution lines. qCL1.2encodesa novel allele of SD1 gene. The wild allele of SD1 is a dominant locus that can significantly promote rice internode length by regulating the expression levels of genes involved in gibberellin biosynthesis and signal transduction. Nucleotide diversity and haplotype network analyses of the SD1 gene were performed using 2822 rice landraces. Two previously reported functional nucleotide polymorphisms clearly differentiated japonica and indica rice; however, they were not associated with PH selection. Other new functional nucleotide polymorphisms in the coding, but not promoter, regions were involved in PH selection during rice domestication. Our study increasesunderstanding of the rice SD1 gene and provides additional evidence of this gene's selection during rice domestication. CONCLUSIONS Our findings provide evidence thatSD1 gene from wild rice enhances plant height and new functional nucleotide polymorphisms of this gene were artificially selected during cultivated rice differentiation.

Abstract
Present study was designed to compared the total flavonoids and polyphenols contents and antibacterial activity of hawthorn extracts with different polarities as well as the underlying antibacterial mechanisms. The results showed that among all hawthorn extracts, methanol and ethanol extracts (ME and EE) exhibited high levels of total flavonoids and polyphenols contents, followed by acetone, ethyl acetate, trichloromethane and petroleum ether extracts. ME exhibited the strongest antibacterial activity against tested bacteria, especially Staphylococcus aureus with a 1.25 μg/mL of the minimum inhibitory concentration (MIC) and minimum bactericide concentration (MBC). Further analysis revealed that the main phenolic compounds from ME were epicatechin (281.6 mg/100 g DW), procyanidin B2 (243.5 mg/100 g DW), chlorogenic acid (84.2 mg/100 g DW) and quercetin (78.4 mg/100 g DW). The action mechanism of ME against S. aureus could be ascribed to ME damaging cell wall and cell membrane integrity, inhibiting intracellular enzyme activity, increasing reactive oxygen species (ROS), also changing expression of associated genes and then inducing apoptosis of S. aureus. In addition, the antimicrobial activity of ME against S. aureus has also been demonstrated to be efficient in the food matrix (whole milk).

Abstract
Objective: To investigate the effect and molecular mechanism of circular RNA-UBXN7 (circ_UBXN7) on the proliferation, migration and apoptosis of hepatocellular carcinoma cells. Methods: Circ_UBXN7 expression in the tissues and cells of hepatocellular cancer was detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the relationship between circ_UBXN7 expression and clinicopathological features, including age, gender, tumor volume, pathological classification, staging, and lymph node metastasis was analyzed. The full-length sequence of circ_UBXN7 with lentivirus carrying lenti circ_UBXN7 and lenti circ_UBXN7 shRNA was constructed to transfect hepatocellular cell lines (HepG2 and Huh-7), respectively. CCK-8 experiments were performed to detect the ability of up- or down-regulation of circ_UBXN7 on the proliferation of HEPG2 and HUH-7 cells. Annexin V / PI experiment was used to detect the changes in apoptosis of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. JC-1 assay was used to detect the changes in mitochondrial potential energy of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. Transwell was used to detect the migration ability of HEPG2 and HUH-7 cells after up-regulation or down-regulation of circ_UBXN7 expression. Western blotting was used to detect the expressional change of TWIST, E-cadherin, N-cadherin and vimentin. Statistical analysis: The expression levels of circ_UBXN7 and clinicopathological features were measured by chi-square test. Two groups were compared by t-test and three groups and above were compared by single factor analysis of variance. LSD method was used for comparison between groups. Results: The expression of circ_UBXN7 in liver cancer tissues was significantly higher than adjacent tissues, and its expression level was significantly positively correlated with tumor volume, stage, and lymph node metastasis (P < 0.05). Lenti-circ_UBXN7 had up-regulated the expression of circ_UBXN7 in HEPG2 and HUH-7 cells and promoted cell proliferation. Lenti-circ_UBXN7-shRNA had down-regulated the expression of circ_UBXN7 and induced apoptosis. Lenti-circ_UBXN7-shRNA had reduced the mitochondrial membrane potential of cells. Lenti-circ_UBXN7 had promoted cell migration, while lenti-circ_UBXN7-shRNA had inhibited cell migration. Lenti-circ_UBXN7 had induced increased expression of Twist, N-cadherin, and Vimentin proteins, and reduced the expression of E-cadherin protein. Lenti-circ_UBXN7-shRNA had opposite effects on the expression levels of each protein. Starbase V2.0 software showed that miR-203a and circ_UBXN7 had potential binding sites, and miR-203a and circ_UBXN7 expression levels were negatively correlated in HEP G2 and HUH-7 cells. Conclusion: circ_UBXN7 plays an important role in promoting the occurrence and development of liver cancer, and is expected to become a potential target for the treatment of liver cancer.

Abstract
Objective: To gain insight into the transcriptional landscape including mRNA, long non-coding RNA (lncRNA), and circular RNA (circRNA) of the differentiated lens. Methods: Experiment research. The total RNAs of the differentiated lenses were extracted and purified. Total RNAs of 16-week, 23-week, and 25-week differentiated lenses were then sequenced using Illumina HiSeq 2500, and analyzed using bioinformatics tools. The top expressed and differentially expressed mRNAs and lncRNAs were screened. The expressions of overlap genes among the 16-week, 23-week, and 25-week lenses were analyzed by Venn diagram. The expression tendency of lens-specific genes was obtained and verified with real-time polymerase chain reaction. Results: A total of 67 518 311 mapped reads were obtained from differentiated lenses at 16 weeks, 99 440 160 at 23 weeks, and 67 262 320 at 25 weeks. The gene overlap expression analysis showed 740 of the top 1 000 highly expressed mRNAs, 170 of the top 300 highly expressed lncRNAs, and 69 of the top 100 highly expressed circRNAs overlapping expressed in lenses at 16, 23, and 25 weeks, respectively. Lens specific gene expression analysis revealed that the expression of crystallin (CRY) AA, CRYGA, CRYGB, CRYGC, CRYGD, CRYGEP, and CRYGS was upregulated, while the expression of gap junction (GJ) A3 and GJA8 was downregulated with the differentiation of lenses. Conclusion: The lens transcriptome profile shows that more than half of the high expressed mRNA, lncRNA and circRNA at different differentiation stages are overlapping expressed, and all of them have high expression of lens specific protein genes, such as CRY, GJ etc. (Chin J Ophthalmol, 2020, 56: 356-363).

Abstract
Objective: To examine the safety and efficacy of minimally invasive coronary surgery-coronary artery bypass grafting (MICS-CABG). Methods: From the first case in November 2015 to November 2019, a total of 244 cases of MICS-CABG were performed in Department of Cardiovascular Surgery, Peking University Third Hospital. There were 197 males and 47 females, aging (62.3±8.7)years (range: 36 to 88 years). The operations were performed via the 5(th) intercostal space of left thoracic lateral incision (length: 4 to 5 cm extended for 8 to 10 cm), and were performed under off-pump, with the help of the chest wall suspension device and cardiac fixator. The proximal anastomosis on ascending aorta and the distal anastomosis of left anterior descending branch, circumflex branch and right coronary system were completed according to procedure. In all 244 cases, the proportion of 2 grafts was 53.7% (131 cases), 3 grafts was 36.1% (88 cases), 4 grafts was 9.8% (24 cases) and 5 grafts was 0.4% (1 case). The average of grafts was 2.6±0.7 (range: 2 to 5). The proportion of hybrid was 14.3% (35 cases), sequential bypass procedure was 43.0% (105 cases) and multiple artery grafts was 25.4% (62 cases). The perioperative complications of the patients were collected, the patency rate of the grafts was evaluated by coronary angiography or CT within 7 days after the operation, and main adverse cardiovascular and cerebrovascular events (MACCE) were followed up. The survival curve was drawn by Kaplan-Meier method, and the 1-year MACCE rate was calculated by survival analysis. Results: All cases had no transition to thoracotomy and cardiopulmonary bypass procedure, and no cases needed intra aortic balloon pumping and extracorporeal membrane oxygenation during the operation.There were 2 cases of poor incision healing, and reoperation was performed in 10 cases (6 cases of postoperative bleeding, 2 cases of incision debridement, and 2 cases of grafts problems). The rate of MACCE in 30 days was 2.6% (10 cases), which contained 3 cases of death (2 cases of grafts occlusion, 1 case of serious hemorrhage after thoracic puncture drainage), 3 cases of stroke and 5 cases of non-fatal myocardial infarction. By the re-examination of angiography in 7 days after operation, the overall patency of the grafts was 96.1%, and the patency of the left anterior descending was 98.6%. Kaplan-Meier survival analysis was conducted for 235 patients (96.3%) with 1 to 36 months follow-up results, and the 1-year MACCE rate was 5.6% (95%CI: 4.2% to 7.0%) . There was no significant difference among the incidences of MACCE at each stage of learning curve. Surgeon could reduce the operation time and complete more anastomosis with the accumulation of experience after the early 30 cases. Conclusions: MICS-CABG can safely achieve completed revascularization, which has good operative effects in short and medium-long term. There is no significant risk in the early cases of learning curve.

Abstract
BACKGROUND Adenosquamous carcinoma (ASC) of the lung is a heterogeneous disease that is composed of both adenocarcinoma components (ACC) and squamous cell carcinoma components (SCCC). Their genomic profile, genetic origin, and clinical management remain controversial. PATIENTS AND METHODS Resected ASC and metastatic tumor in regional lymph nodes (LNs) were collected. The ACC and SCCC were separated by microdissection of primary tumor. The 1021 cancer-related genes were evaluated by next-generation sequencing independently in ACC and SCCC and LNs. Shared and private alterations in the two components were investigated. In addition, genomic profiles of independent cohorts of adenocarcinomas and squamous cell carcinomas were examined for comparison. We have also carried out a retrospective study of ASCs with known EGFR mutation status from 11 hospitals in China for their clinical outcomes. RESULTS The most frequent alterations in 28 surgically resected ASCs include EGFR (79%), TP53 (68%), MAP3K1 (14%) mutations, EGFR amplifications (32%), and MDM2 amplifications (18%). Twenty-seven patients (96%) had shared variations between ACC and SCCC, and pure SCCC metastases were not found in metastatic LNs among these patients. Only one patient with geographically separated ACC and SCCC had no shared mutations. Inter-component heterogeneity was a common genetic event of ACC and SCCC. The genomic profile of ASC was similar to that of 170 adenocarcinomas, but different from that of 62 squamous cell carcinomas. The incidence of EGFR mutations in the retrospective analysis of 517 ASCs was 51.8%. Among the 129 EGFR-positive patients who received EGFR-TKIs, the objective response rate was 56.6% and the median progression-free survival was 10.1 months (95% confidence interval: 9.0-11.2). CONCLUSIONS The ACC and SCCC share a monoclonal origin, a majority with genetically inter-component heterogeneity. ASC may represent a subtype of adenocarcinoma with EGFR mutation being the most common genomic anomaly and sharing similar efficacy to EGFR TKI.

Abstract
Background Eimeria tenella is a highly pathogenic coccidian that causes avian coccidiosis. Both nitromezuril (NZL) and ethanamizuril (EZL) are novel triazine compounds with high anticoccidial activity, but the mechanisms of their action are still unclear. This study explored the response of E. tenella to NZL and EZL by the study of changes in protein composition of the second-generation merozoites. Methods Label-free quantification (LFQ) proteomics of the second-generation merozoites of E. tenella following NZL and EZL treatment were studied by LC-MS/MS to explore the mechanisms of action. The identified proteins were annotated and analyzed by Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and protein-protein interaction (PPI) networks analysis. Results A total of 1430 proteins were identified by LC-MS/MS, of which 375 were considered as differential proteins in response to drug treatment (DPs). There were 26 only found in the NZL treatment group (N-group), 63 exclusive to the EZL treatment group (E-group), and 80 proteins were present in both drug groups. In addition, among the DPs, the abundant proteins with significantly altered expression in response to drug treatment (SDPs) were found compared with the C-group, of which 49 were upregulated and 51 were downregulated in the N-group, and 66 upregulated and 79 downregulated in the E-group. Many upregulated proteins after drug treatment were involved in transcription and protein metabolism, and surface antigen proteins (SAGs) were among the largest proportion of the downregulated SDPs. Results showed the top two enriched GO terms and the top one enriched pathway treated with EZL and NZL were related, which indicated that these two compounds had similar modes of action. Conclusions LFQ proteomic analysis is a feasible method for screening drug-related proteins. Drug treatment affected transcription and protein metabolism, and SAGs were also affected significantly. This study provided new insights into the effects of triazine anticoccidials against E. tenella.![]()

Abstract
OBJECTIVE To compare the expression of serum vitamin D in advanced schistosomiasis patients with grade I and II hepatic fibrosis, and to preliminarily examine its associations with the internal diameter of the main portal vein and progression of hepatic fibrosis. METHODS The medical records of 126 advanced schistosomiasis patients with grade I and II hepatic fibrosis referred to Jiaxing First Hospital from March 2012 to September 2015 were retrospectively analyzed. The internal diameter of the main portal vein and serum 25-hydroxyvitamin D3 [25(OH)D3] level were measured. The progression of hepatic fibrosis was followed up, and the serum vitamin D level was compared between patient with disease progression and stable disease. RESULTS The 126 advanced schistosomiasis patients included 72 men and 54 women, and had ages of 62 to 80 years. There were 58 cases with grade I hepatic fibrosis and 68 cases with grade II hepatic fibrosis. There were significant differences between patients with grade I and II hepatic fibrosis in terms of hemoglobin, white blood cell count, prothrombin time, international normalized ratio, activated partial thromboplastin time, fibrinogen or 25(OH)D3 level (all P > 0.05), and significant differences were seen in alanine aminotransferase, aspartate aminotransferase, blood calcium, blood phosphorus levels and the internal diameter of the main portal vein (all P values < 0.05). In addition, a lower serum 25(OH)D3 level was detected in patients with broadened internal diameter of the main portal vein than in those with normal internal diameter of the main portal vein [(19.08 ± 1.36) nmol/L vs. (25.61 ± 6.69) nmol/L, P < 0.05]. Following 3-year follow-up, there were 73 cases with progression of hepatic fibrosis, and a significantly lower serum vitamin D level was found in patients with disease progression than in those with stable disease [(20.00 ± 0.81) nmol/L vs. (25.47 ± 5.91) nmol/L, P < 0.05]. CONCLUSIONS Vitamin D deficiency is common in advanced schistosomiasis patients with hepatic fibrosis, and it may be associated with the internal diameter of the main portal vein and the progression of hepatic fibrosis disease.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the common causes for chronic liver diseases, which progress gradually from nonalcoholic type simple fatty liver disease to hepatitis, cirrhosis and even liver failure and hepatocellular carcinoma. Sarcopenia is a progressive disease characterized by reduced skeletal muscle mass and function in association to metabolic dysfunctions. Recent studies have shown that the occurrence and development of NAFLD and sarcopenia are related, and there is a common base for the pathogenesis between the two, which may promote each other for mutual risk factors. This article reviews the current research progress of this field in order to clinically further understand the pathogenesis and intrinsic links between the two to look for appropriate interventions.

Abstract
OBJECTIVE To evaluate the expression of translocator protein (TSPO) in brain tissue within 72 h after subarachnoid hemorrhage (SAH) in mice. METHODS Forty-four C57BL/6J mice were randomly divided into two groups, 17 in the Sham group and 27 in the SAH group. SAH mice model was performed by endovascular perforation as previously described with slight modifications. Sham group mice were performed by the same method but without piercing the blood vessels. Before and 6 h, 24 h, 48 h, 72 h after modeling, the two groups were scored with modified Garcia score for neurological function. At 6 h, 24 h, 48 h, 72 h after modeling, the mice were sacrificed. Sham group mice were sacrificed at 24 h after modeling. The expression of TSPO in brain tissue was evaluated by Western blot, positron emission tomography-computed tomography (PET-CT) and immunofluorescence staining. Fluorescent double staining was used to assess the relationship of TSPO and microglia. RESULTS The neurological function scores of the SAH group mice decreased with time and then increased. The expression of TSPO in the brain tissue increased first and then decreased with time, and there was a negative correlation between them (r=-0.615 6, P < 0.01). PET-CT showed that the tracer intake of mouse brain tissue after SAH was higher than that of Sham group, and the difference was statistically significant (P < 0.05). Immunofluorescence staining showed that TSPO increased in the parietal cortex and basal cortex of the SAH group. And fluorescent double staining suggested that TSPO colocalized with Iba-1 which was a specific marker of microglia. CONCLUSIONS In the early brain injury after SAH, the expression of TSPO in brain is widely increased, and the expression level increases first and then decreases. TSPO could participate in the activation of microglia and regulate the occurrence and development of brain injury after SAH.

Abstract
Hypofractionated stereotactic radiotherapy (HFSRT) is a common salvage treatment for recurrent malignant glioma (MG). However, it remains controversial whether the combination of HFSRT and chemotherapy could improve survival for patients with recurrent MG compared to HFSRT alone. The present systematic review and meta-analysis aims to investigate this question, and tries to determine to what extent the addition of chemotherapy to HFSRT affects survival. A systematic review was performed to analyse the survival for patients treated with HFSRT combined with chemotherapy or not. Hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS) were pooled with random effects; and standard mean difference (MD) with 95% CIs for OS were pooled using the same strategy. A total of 7 studies including 388 patients with recurrent MG were eligible for our study. The OS survival of patients receiving combination therapy ranged from 8.7 to 23 months, and the median OS of patients underwent HFSRT ranged from 3.9 to 12 months. The meta-analyses resulted in the pooled HR of 0.44 (95% CI 0.30-0.65, p < 0.0001) (Cochran Q statistic 4.70, P = 0.320, I2 = 14.8%) and pooled standard MD of 0.80 months (95% CI 0.41-1.18, p < 0.001) (Cochran Q statistic 10.16, p = 0.71, I2 = 50.8%). The present study suggests that HFSRT + chemotherapy confers a slight survival improvement for patients with recurrent MG as compared with sole HFSRT management. To draw a more solid conclusion, greater investigation is warranted.

Abstract
Eight C_(19)-diterpenoid alkaloids( 1-8) were isolated from the ethyl acetate soluble fraction of 95% ethanol extract of the ground roots of Aconitum austroyunnanense through various column chromatographies on silica gel,ODS,Sephadex LH-20 and MCI gel.Their structures were elucidated as 14α-benzoyloxy-13β,15α-dihydroxy-1α,6α,8β,16β,18-pentamethoxy-19-oxoaconitan( 1),N-deethylaconitine( 2),spicatine B( 3),leucanthumsine A( 4),acofamine B( 5),macrorhynine B( 6),aconitilearine( 7),and ambiguine( 8) based on their chemical and physicochemical properties and spectroscopic data. Compound 1 was a new compound and alkaloids 2-8 were isolated from this plant for the first time. Some isolated alkaloids were tested in vitro for cytotoxic potential by employing the MTT method. As a result,alkaloid 1 exhibited weak cytotoxic activity against three tested tumor cell lines( A-549,He La,and Hep G2) with IC_(50) values less than 20 μmol·L~(-1).

Abstract
Objective: To summarize the early experience and clinical value of minimally invasive coronary surgery-total arterial coronary revascularization (MICS-TACR) through the left anterior small incision. Methods: Between May 2015 and June 2018, a total of 31 consecutive cases [21 males and 10 females, aged (63.2±9.3) years] in Peking University Third Hospital who were performed MICS-TACR with bilateral internal mammary artery and radial artery were enrolled. Meanwhile, 1 489 cases of conventional median sternal incision off-pump coronary artery bypass grafting (OPCABG) were matched as control group. According to exclusion criteria and matching score, 90 cases [55 males and 35 females, aged (63.8±9.5) years] were selected as the control group, and the perioperative data of the two groups were compared. All patients in MICS-TACR group underwent postoperative angiography and the graft patency was evaluated. Results: There were no statistically significant differences in baseline data between the two groups. The perioperative blood transfusion of MICS-TACR group was less than control group [0(0,0) U vs 0(0,4) U, P=0.003]. There were no statistically significant differences in operative mortality, intraoperative and postoperative intra-aortic balloon pump (IABP) and extracorporeal membrane oxygenation (ECMO) use, re-operation rate, perioperative major adverse cardiac and cerebrovascular events (MACCE), new-onset renal failure, atrial fibrillation, and multiple organ failure between the two groups. Postoperative angiography showed that there was no significant difference in the patency rate between the MICS-TACR group and control group(all P>0.05). Conclusion: Total arterial coronary revascularization can be successfully accomplished under the left anterior small incision, and the early clinical outcome is satisfied.

Abstract
Objective: To investigate surface electromyography signal (sEMG) of the major back muscle group and subjective fatigue assessment under different experimental combinations during walk with weight on both shoulders, as well as the functional status and fatigue property of human muscles. Methods: From October to December, 2017, 10 college students were recruited to participate in shoulder weight-bearing work and walk under the combinations of different shoulder strap widths, weights, and hardness of waist cushion. The subjects were required to complete 12 sets of experiments, with each set lasting for 15 minutes, and the rest time between work was 30 minutes. The sEMG signals of the upper trapezius and the erector spinae were measured during the experiment, and subjective fatigue assessment was performed during rest. The time domain evaluation index (average amplitude, aEMG) , the frequency domain evaluation index (median frequency, MF) , and the data of subjective assessment were processed and analyzed. Results: Weight and shoulder strap width had a significantly effect on fatigue (P<0.01) , and the change in the hardness of waist cushion had no significant effect on fatigue (P>0.05) . There was an interaction effect between weight and shoulder strap width (P<0.01) , and there was no interaction effect between weight, shoulder strap width, and hardness of waist cushion (P>0.05) . For the backpack carrying system, the combination of 10% weight and 50 mm shoulder strap width was the best one for relieving fatigue. The subjective test also showed that subjective feelings of muscle fatigue were associated with the weight and width, which was consistent with sEMG results. Conclusion: The results of this experiment show that the combination of 10% weight and 50 mm shoulder strap width can help to relieve muscle fatigue during walk with weight on both shoulders, and weight-bearing walking is more likely to cause the fatigue of the erector spinae.

Abstract
Objective: To examine the association between progesterone concentration in early pregnancy and duration of pregnancy and risk of preterm delivery.Methods: Women enrolled in the Born in Guangzhou Cohort Study from 2013-2014, with a singleton pregnancy, who had serum progesterone measured at least one time between 4 and 10 weeks of gestation were included. The association between progesterone concentration both continuous and as categorical variable (quartile) and the risk of preterm delivery was assessed with Cox proportional hazards regression. Differences of length of gestation in four progesterone concentration quartiles were assessed using the Log-rank test.Results: We studied 1860 mother-newborn pairs. The mean overall progesterone concentration was 65.7 ± 21.3 nmol/L, with mean progesterone concentrations in the four quartiles of 42.4 ± 6.2 nmol/L (n = 463), 56.2 ± 3.3 nmol/L (n = 462), 68.9 ± 4.5 nmol/L (n = 470), and 95.1 ± 15.3 nmol/L (n = 465). There was no significantly difference in duration of gestation in four progesterone concentration groups (p=.511). There was no relation between progesterone level and preterm delivery (adjusted hazard ratio (HR) per 10 nmol/l progesterone level 1.00 (95% confidence interval (CI) 0.90, 1.11)). After adjusting for potential confounders, the HR of any preterm delivery for quartiles 1, 2 and 3 versus the highest quartile of progesterone level (> 77.3 nmol/L) was 1.04 (95% CI 0.52, 2.07), 1.17 (95% CI 0.60, 2.28), and 1.46 (95% CI 0.76, 2.78), respectively. When analysis was done for spontaneous preterm delivery only, also no association with first trimester progesterone was found.Conclusion: Lower first trimester serum progesterone concentration is not associated with reduction of length of gestation or increased risk of preterm delivery.

Abstract
Aerobic granular sludge (AGS) was cultivated in a sequencing batch reactor (SBR). In this study, AGS was broken during the formation process and then mature AGS formed again. The microbial community dynamics during two sludge granulation processes were investigated using high-throughput sequencing to reveal the dominant bacteria beneficial to AGS formation. The abundance dynamics of nitrifying microorganisms were analyzed by a quantitative polymerase chain reaction (qPCR). The results showed that the amount of extracellular protein and polysaccharides increased during two sludge granulation processes. The abundance of ammonia oxidizing archaea (AOA) increased during the first AGS formation process and during the process of AGS maturation. The abundance of ammonia oxidizing bacteria (AOB) decreased during the first AGS formation process, while it maintained a higher abundance than AOA during AGS cultivation. Microbial diversity decreased with AGS formation. The relative abundance of Proteobacteria increased by 12.29% and 5.90% during two sludge granulation processes, respectively. Candidatus Competibacter belonging to Proteobacteria was enriched during two sludge granulation processes, accounting for 14.20% in mature AGS. Overall, extracellular protein and polysaccharides may have contributed to the sludge granulation. Both AOA and AOB might have been involved in ammonia oxidation. This study indicated that Ca. Competibacter might contribute to AGS formation.

Abstract
Objective: To access the influence factors of diagnostic delay of endometriosis. Methods: We designed a questionnaire of diagnostic delay of endometriosis. From February 2014 to February 2016, 400 patients who had dysmenorrhea and diagnosed with endometriosis by surgery in Peking University Third Hospital were surveyed retrospectively. Time and risk factors of diagnostic delay were analyzed. Results: The diagnostic delay of 400 patients was 13.0 years (0.2-43.0 years), 78.5%(314/400) patients thought pain was a normal phenomenon and didn't see the doctor. Patients who suffered dysmenorrhea at menarche experienced longer diagnostic delay than those who had dysmenorrhea after menarche (18.0 vs 4.5 years; Z=191.800, P<0.01) . Patients who suffered aggravating dysmenorrhea experienced shorter delay time than those who suffered stable or relieving dysmenorrhea (11.0 vs 12.5 vs 18.0 years; Z=8.270, P<0.05) , with the difference statistically significant, single factor analysis shows. Severe dysmenorrhea, deep infiltration endometriosis (DIE) , family history of dysmenorrhea or endometriosis, previous surgical history of endometriosis, high stage, with infertility, adenomyoma or other symptoms, could help to shorten diagnostic delay with no significant difference (P>0.05) . By multiple logistic regression analysis, the results shown that whether have dysmenorrhea at menarche and clinical diagnosis time were the independent factors affecting delayed diagnosis (P<0.01) . Conclusions: Diagnostic delay of endometriosis is common and the mean delay time is 13.0 years mainly due to the unawareness of dysmenorrhea. Dysmenorrhea at menarche, clinical diagnosis time and dysmenorrhea intensity are the factors affecting time of diagnostic delay.

Abstract
Objective: To estimate the association between high-sensitivity C-reactive protein (hs-CRP) and cardiovascular events as well as all-cause mortality events. Methods: During 2009- 2010, out of the 11 623 individuals, 1 000 participants aged 35-64 years, were recruited and divided into 12 age-groups, to have received a study on CVD risk factors. Information on the risk factors of cardiovascular diseases was also collected. Fasting blood sample was gathered for all the participants, with hs-CRP tested. Participants in 7 out of the 12 sites were followed, with 6.21 years (36 075 person-years) as the median follow-up period. Cardiovascular and all-cause mortality events were collected. A total of 6 177 participants had been followed after excluding participants who had baseline infections, or did not take hs-CRP test/physical examination at the baseline. Finally, 5 984 participants were included for analysis. Participants were categorized into three groups based on the hs-CRP (mg/L) values: <1, 1-3 and >3, respectively. Cox proportional hazards regression model was used to analyze the relationships between hs-CRP with cardiovascular events or all-cause mortality events, after adjusting for confounding factors. Results: Mean age of the participants was 50.2 years. The incidence rates of cardiovascular disease events were 3.6/1 000 person-years, 7.1/1 000 person-years,and 10.4/1 000 person-years among three groups and 3.0/1 000 person-years, 5.7/1 000 person-years, 9.1/1 000 person-years for all-cause mortality events, respectively. After adjusting for confounding factors, the hazard risks (HR) for cardiovascular events were 1.33 (95%CI: 0.95-1.84) in the hs-CRP 1-3 mg/L group and 1.76 (95%CI: 1.20-2.60) in the hs-CRP>3 mg/L group when comparing with the hs-CRP<1 mg/L group (trend test P=0.003). The HRs for all-cause mortality events were 1.76 (95%CI: 1.23-2.54) and 2.64 (95%CI: 1.74-4.01) (trend test P<0.001), respectively. Conclusion: Hs-CRP appeared an independent predictor for cardiovascular events and all-cause mortality events.

Abstract
Shifts in bacterial community composition and abundance of nitrifiers during aerobic granulation, and the effects of wastewater composition on them were investigated using Illumina sequencing and quantitative PCR. The bacterial diversity decreased sharply during the post-granulation period. Although cultivated with different wastewater types, aerobic granular sludge (AGS) formed with similar bacterial structure. The bacterial structure in AGS was completely different from that of seed sludge. The minor genera in seed sludge, e.g., Arcobacter, Aeromonas, Flavobacterium and Acinetobacter, became the dominant genera in AGS. These genera have the potential to secrete excess extracellular polymer substances. Whereas, the dominant genera in seed sludge were found in less amount or even disappeared in AGS. During aerobic granulation, ammonia-oxidizing archaea were gradually washed-out. While, ammonia-oxidizing bacteria, complete ammonia oxidizers and nitrite-oxidizing bacteria were retained. Overall, in this study, the bacterial genera with low relative abundance in seed sludge are important for aerobic granulation.
