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
Early brain injury (EBI) following subarachnoid hemorrhage (SAH) is characterized by rapid development of neuron apoptosis and dysregulated inflammatory response. Microglia efferocytosis plays a critical role in the clearance of apoptotic cells, attenuation of inflammation, and minimizing brain injury in various pathological conditions. Here, using a mouse SAH model, we aim to investigate whether microglia efferocytosis is involved in post-SAH inflammation and to determine the underlying signaling pathway. We hypothesized that TAM receptors and their ligands regulate this process. To prove our hypothesis, the expression and cellular location of TAM (Tyro3, Axl, and Mertk) receptors and their ligands growth arrest-specific 6 (Gas6) and Protein S (ProS1) were examined by PCR, western blots, and fluorescence immunostaining. Thirty minutes after SAH, mice received an intraventricular injection of recombinant Gas6 (rGas6) or recombinant ProS1 (rPros1) and underwent evaluations of inflammatory mediator expression, neurological deficits, and blood-brain barrier integrity at 24 h. Microglia efferocytosis of apoptotic neurons was analyzed in vivo and in vitro. The potential mechanism was determined by inhibiting or knocking down TAM receptors and Rac1 by specific inhibitors or siRNA. SAH induced upregulation of Axl and its ligand Gas6. The administration of rGas6 but not rPros1 promoted microglia efferocytosis, alleviated inflammation, and ameliorated SAH-induced BBB breakdown and neurological deficits. The beneficial effects of rGas6 were arrogated by inhibiting or knocking down Axl and Rac1. We concluded that rGas6 attenuated the development of early brain injury in mice after SAH by facilitating microglia efferocytosis and preventing inflammatory response, which is partly dependent on activation of Axl and Rac1.

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
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
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
Fine roots play an important role in energy flow and substance cycling in forests. How-ever, the estimates of biomass, production and turnover of fine roots remain large uncertainties, and the mechanism underlying local-scale spatial variation in fine roots is still unclear. In a temperate secondary forest in the Maoer Mountain in Northeast China, we investigated the vertical distribution of fine root biomass and necromass at the 0-100 cm profile and the dynamics, production and turnover rate of fine root in 0-20 cm soil layer. The sequential coring (including the Decision Matrix and the Maximum-Minimum formula) and the ingrowth core (3 cm diameter and 5 cm diameter) were compared in estimating production and turnover rate of fine roots. Forest stand variables that might affect fine roots were also explored. The results showed that 76.8% of fine root biomass and 62.9% of necromass concentrated in the 0-20 cm soil layer, and that both decreased exponentially with increa-sing soil depth. The seasonal variation in both fine root biomass and necromass was not significant in 0-20 cm soil layer, which might be related to the negligible snowfall in winter and the extremely high precipitation in summer. There was no significant difference in the results of the estimated fine root production between two diameter ingrowth cores. After log-transformed, fine root production and turnover rate estimated by the Decision Matrix, the Maximum-Minimum formula and ingrowth cores were significantly different among methods. With the increases of soil nutrient concentrations, fine root biomass/fine root necromass ratio significantly increased, fine root necromass significantly decreased, whereas fine root biomass, productivity, and turnover rate were not related to soil nutrient. There was a significant positive correlation between fine root production and aboveground woody biomass increment in the previous-year but not current-year.

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
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
Herein, we report our strategy to develop the efficient chemosensor and real-time monitoring technique for cyanuric chloride (TCT) detection. A luminescent macrocyclic mononuclear Sm(III) complex Sm-2k bearing with two dynamic imine bonds has been constructed via the template synthesis between dialdehyde H2Qk and matched diamine 1,2-bis(2-aminoethoxy)ethane. Sensing experiments reveal that complex Sm-2k exhibits the turn-off fluorescent and colorimetric response for TCT in CH3OH. It is especially encouraging that this optical sensing process is not only rapid within 60 s but also high-efficient in the presence of TCT analogues as well as sensitive with the low limit of detection (LOD, 1.74 μM) and wide linear sensing range. Mechanism studies demonstrate that TCT sensing is mainly based on the imine bond transformation of probe Sm-2k, which is due to the increased acidity induced by TCT. Meanwhile, a smartphone-based analytical method was developed to make complex Sm-2k accessible for the real-time TCT detection by RGB value outputs. It is believed that this work can shed some constructive lights on design of chemosensors and convenient detection technique for highly reactive analytes.

Abstract
Long non-coding RNAs (lncRNAs) may be a regulatory factor of tumorigenesis. However, it is unclear what its biomechanisms are in breast cancer. In this study, different lncRNAs were detected in breast cancer through microarray analysis (GSE119233) and LINC01705 was selected for further study. qRT-PCR was then utilized for the detection of LINC01705 expression in breast cancer cells. A transwell assay, flow cytometry, 5-ethynyl-2'-deoxyuridine (EdU), a cell counting Kit-8 (CCK-8), and a wound-healing assay were performed to determine cell migration, invasion, apoptosis, and proliferation in breast cancer, respectively. For the identification of potential targets of LINC01705, dual-luciferase reporter gene and bioinformatics assays were conducted. Moreover, for the clarification of their interaction and roles in the regulation of the occurrence of breast cancer, Western blotting and RIP assays were conducted. Our findings revealed high LINC01705 expression in breast cancer tissues relative to adjacent non-cancerous tissues (n = 40, P < 0.001). Overexpression of LINC01705 notably enhanced cell migration and proliferation in breast cancer. In addition, LINC01705 positively regulated the translocated promoter region, nuclear basket protein (TPR) through competition with miR-186-5p. In conclusion, our results suggest that LINC01705 is implicated in the progression of breast cancer via competitively binding to miR-186-5p as a competing endogenous RNA (ceRNA), thereby regulating TPR expression.

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.

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
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
Here, we report our trials to regulate the luminescence performance of the macrocyclic samarium(III) complex and prepare four excellent luminescent Sm(III) complex-doped poly(methylmethacrylate) (PMMA) composites. Four 23-membered [1 + 1] Schiff-base macrocyclic mononuclear Sm(III) complexes, Sm-2 a -Sm-2 d , originating from dialdehydes with different pendant arms and 1,2-bis(2-aminoethoxy)ethane, have been constructed by the template method. Crystal structures reveal that every Sm(III) ion with the coordination geometry of a distorted bicapped square antiprism is capsulated by the macrocyclic cavity environment forming the "lasso-type" protection. Relative photophysical properties of macrocyclic Sm(III) complexes are carefully investigated in solid-state, methanol solution, and doped PMMA film, and all these show characteristic emissions of the Sm(III) ion associated with satisfactory lifetimes and quantum yields in all media, which could be comparable to reported outstanding examples. Especially, the luminescence performance for this type of Sm(III) complex could be regulated in the solid state by the use of different functional groups in the pendant arm while it is not achieved in solution and the doped PMMA composite. High emitting and air-stable plastic materials could be obtained when these Sm(III) complexes are doped in PMMA with 0.1 wt % mixing ratio, and the corresponding maximum lifetime and quantum yield are 61.2 μs and 0.63% in the case of complex Sm-2 a , respectively. We believe that these highly luminescent "lasso-type" Sm(III) complexes and doped PMMA composites are valuable references in the design of luminescent lanthanide(III) hybrid materials.

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
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
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 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
OBJECTIVE To compare the safety and effectiveness of two minimally invasive approaches for multi-vessel coronary revascularization. METHODS From August 2014 to February 2017, 70 consecutive patients who underwent minimally invasive coronary artery bypass grafting in Peking University Third Hospital were randomly divided into two groups. In one group, 40 patients underwent staged-hybrid coronary revascularization (staged-HCR) treatment; in the other group, 30 patients underwent minimally invasive total arterial revascularization with bilateral internal thoracic artery (BITA). In staged -HCR group, the patients underwent minimally invasive direct coronary artery bypass grafting (MIDCAB) and percutaneous coronary intervention (PCI) procedure for treatment of multi-vessel disease. In BITA group, the patients underwent total arterial coronary artery bypass grafting with composite "Y" BITA graft. Preoperative and postoperative data of the two groups, including postoperative blood usage, mechanical ventilation time, domiciling duration in intensive care unit (ICU), major adverse cerebral and cardiovascular event (MACCE), and postoperative coronary angiography results were compared, in order to evaluate the safety and effectiveness of these surgical approaches. RESULTS The preoperative characteristics of 70 patients in the two groups showed no significant difference. All the patients underwent successfully, elective minimally invasive multi-vessel coronary artery bypass grafting as scheduled preoperatively. Postoperative result showed the patients in staged-HCR group took advantages in less postoperative mechanical ventilation time [Staged-HCR group (11.2±8.7) h vs. BITA group (18.3±9.1) h, P=0.013], shorter domiciling duration in ICU [Staged-HCR group (26.29±4.05) h vs. BITA group (44.74±28.75) h, P=0.022], and less total drainage [Staged-HCR group (695.57±250.46) mL vs. BITA group (1 103.26±547.44) mL, P=0.03] than the patients in the group of minimally invasive total arterial revascularization with BITA. Postoperative in hospital coronary angiography showed satisfactory graft patency rates in both groups [97.5% in Staged-HCR group vs. 97.8% in BITA group]. No MACCE occurred in both groups during hospitalization. CONCLUSION Staged-HCR is a feasible method for the treatment of multi-vessel revascularization involving right coronary artery. Minimally coronary revascularization with BITA is associated with superior long-term graft patency and it's recommended for patients who could not tolerate dual-antiplatelet therapy. This study shows that both minimally invasive surgical approaches are safe and effective for treatment of patients with multi-vessel coronary artery disease.

Abstract
OBJECTIVE To explore the surgical strategies for the treatment of T1b gallbladder cancer patients diagnosed intraoperatively or postoperatively. METHODS A retrospective analysis of 42 patients with T1b gallbladder cancers was performed. There were 14 patients diagnosed intraoperatively and 28 patients diagnosed postoperatively. The reevaluations of T stages were conducted in the 28 T1b gallbladder cancer patients diagnosed postoperatively by the professional pathologist. After T stage reevaluation, 25 confirmed T1b patients with complete follow-up data were divided into simple cholecystectomy group and ra-dical resection group, and the clinicopathologic characteristics between the two groups were analyzed. RESULTS Only 2 of the 14 T1b gallbladder cancer patients diagnosed by the intraoperative frozen specimen proved to be T1b on postoperative paraffin pathology, and for the remaining 13 patients, T2 was in 11 patients, and T3 in one patient. The rate of misdiagnosis was 85.7% by the intraoperative frozen specimens, postoperative T stages were equal or higher than intraoperative T stages. Two of the 28 postoperatively diagnosed T1b patients were proved to be T2 after reevaluation, the rate of misdiagnosis was 7.1%, the reevaluated T stages were equal to or higher than the previous stages. Twenty-five confirmed T1b gallbladder cancer patients had complete follow-up data, 11 of whom underwent simple cholecystectomy and the remaining 14 radical resections. No patient had vessel or perineural invasion on pathology in the 25 confirmed T1b patients. Metastasis was absent in all the 30 lymph nodes examined, which achieved from 14 patients with radical resection. The survival rate after simple cholecystectomy was comparable to that after radical resection (P=0.361). Only one patient with radical resection had abdominal cavity implantation relapse, who received gallbladder compression during operation and 2 years later died from metastasis. CONCLUSION Intraoperatively diagnosed T1b gallbladder cancer should receive radical resection. Reevaluation of the T stage is necessary and the initial step for postoperative diagnosed T1b gallbladder cancer patients. The pros and cons of radical surgery for definitive T1b patients should be carefully evaluated, and systemic chemotherapy is recommended for those with bile spillover.

Abstract
Objective: To investigate and analyze distribution characteristics of two multidrug resistance related genes in broiler isolates in Shandong province. Methods: The pre slaughter broilers were chosen from Shandong province in this study in June, 2014. A total of 400 fecal samples from five different zones (east, south, west, north and middle) of the hen house were collected. 373(77.2%) Escherichia coli and 110 (22.8%) Klebsiella pneumonia strains were isolated, and ISCR1 and int1 gene were detected by PCR assay and sequencing. The resistance to 10 drugs belonging to 8 classes antimicrobial drugs were obtained by using minimal broth dilution method and data analysis. The difference between isolates and drug resistance profiles was analyzed. Results: Among 483 isolates, 440 isolates (91.1%), 126 isolates (26.1%) and 126 isolates (26.1%) were detected as int1, ISCR1 and both two gene carriers, respectively. The rate of 37 E. coli isolates not carried ISCR1 or int1 gene resistant to 0 to 2, 3 to 5, 6 to 8 classes antimicrobial agents was 13.5% (n=5), 78.4% (n=29), and 8.1% (n=3), respectively; the rate of 288 only int1 gene E. coli carriers resistant to 0 to 2, 3 to 5, 6 to 8 groups antimicrobial agents was 2.4% (n=7), 74.7% (n=215), and 22.9% (n=6), respectively. The data above showed significant difference (P<0.001). The rate of 26 only int1 gene K. pneumonia carriers resistant to 0 to 2, 3 to 5, 6 to 8 classes antimicrobial agents was 11.5% (n=3), 76.9% (n=20), and 11.5% (n=3), respectively; the rate of 78 both two gene K. pneumonia carriers resistant to0 to 2, 3 to 5, 6 to 8 groups antimicrobial agents was 0, 35.9% (n=28), and 64.1% (n=50), respectively. The data above showed significant difference (P<0.001). Conclusion: Gene int1 and ISCR1 showed high prevalence in E. coli and K. pneumonia isolates. High level multi-drug resistance profile could be mediated by int1 and ISCR1 gene co-existence.

Abstract
The aim of this study was to investigate the mechanism of propranolol on the regression of hemangiomas. Propranolol-treated hemangioma tissues were collected and the expression of hypoxia inducible factor-1α (HIF-1α) was examined. We also established HIF-1α overexpression and knockdown hemangioma cells, and determined the effects of HIF-1α on the hemangioma cells proliferation, apoptosis, migration and tube formation. Significantly increased HIF-1α level was found in the hemangioma tissues compared to that in normal vascular tissues, whereas propranolol treatment decreased the HIF-1α level in hemangioma tissues in a time- and dose-dependent manner. Moreover, propranolol treatment significantly decreased cell proliferation, migration and tube formation as well as promoted cell apoptosis in HIF-1α overexpression and knockdown hemangioma cells. Propranolol suppressed the cells proliferation, migration and tube formation of hemangioma cells through HIF-1α dependent mechanisms. HIF-1α could serve as a novel target in the treatment of hemangiomas.

Abstract
Objective: To investigate the association between types of obesity and the 10-year-coronary heart disease risk in Tibet and Xinjiang of China. Methods: Using the multi-stage random sampling method, 7 631 participants aged 35 or older were examined under the International Standardized Examination process but with only 5 802 were eligible for analysis, in the 2015-2016 season. Results: The prevalence rates of general obesity, central obesity, visceral obesity and compound obesity were 0.53%, 12.62%, 10.08% and 42.35%, respectively. Out of all the compound obesity cases, 58.65% (1 441/2 457) of them appeared as having all types of obesity in our study. Risk related to the 10-year-coronary heart disease was higher in men than in women [(3.05±4.14)% vs. (1.42±2.37) %, P<0.000 1. Compound obesity (30.16%) showed the highest proportion on the risk of 10-year-coronary heart disease than central obesity (28.01%), visceral obesity (18.46%) or the general obesity (19.35%). After adjustment for confounding factors, results from the multivariate analysis showed the risk in compound obesity was higher than central obesity, visceral obesity or general obesity and was associated with the highest risk on the 10-year-coronary heart disease (OR=2.889, 95%CI: 2.525-3.305). People with anomalous BMI and WC seemed to have had the higher risk (OR=3.168, 95%CI: 2.730-3.677). Conclusions: Obesity was popular in the residents of Tibet and Xinjiang areas of China. Men and people with compound obesity (especially both BMI and WC were abnormal) seemed to carry greater risk on the 10-year-coronary heart disease.

Abstract
Objective: Through two nationwide sero-epidemiological survey programs on hepatitis B virus (HBV), hepatitis B markers in Yunnan province were compared between the findings in 2014 and in 2006. Results were used to understand the HBV epidemic status in Yunnan province and to estimate the efficiency of measures on prevention and control of the disease. Methods: People at the age of 1-29 years were sampled from 6 counties of the National Disease Surveillance sites in Yunnan province, by multi-stage random sampling method. Demographic information was collected by questionnaire, and 2-4 ml serum sample was taken to detect HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe, by ELISA method. Results: were logged-in the database and analyzed by SPSS 17.0. Results Between the two studies, no statistically significant differences were observed on the overall HBV infection rates and the positive rates of HBsAg, HBeAg, anti-HBe, anti-HBc. Positive rate of anti-HBs in 2014 was significantly higher than that in 2006. The main two combination profiles of hepatitis B markers were through the fifth model which was positive only for anti-HBs and the sixth model which was negative for all markers in 2006, and the same in 2014. Detection rate through the fifth profile in 2014 was significantly higher than the rate in 2006, while the detection rate of the sixth profile in 2014 was significantly lower than the one in 2006. When analyzing the differences in the same age group, between the two surveys, results showed that the positive rate of anti-HBs in 2014 was significantly higher than that in 2006, in both the10-14 and the 15-19 years-old groups. Positive rate of anti-HBc in the 20-29 year-olds in 2014 was significantly lower than the one of 2006. The positive rates of HBsAg in the age groups of 1-4, 5-14 and 15-29 were 1.12%,1.61% and 1.25% respectively, in 2014. Conclusion: Prevention and control measures on HBV seemed in great progres. However, more effective prevention and control measures should be taken continually among people under the age of 15, in Yunnan province.

Objective: To investigate the association between body fat percentage (BFP), visceral fat index (VFI) and Cardiometabolic Risk Factor Clustering (CRFC), among population aged 35 or older in Tibet and Xinjiang areas. Methods: Using the stratified multi-stage random sampling method, 7 571 residents aged 35 or above were examined with international standardized examination between 2015 and 2016. Of the eligible 5 643 participants, association of BFP and VFI with CRFC was defined as having two or more of the four risk factors: hypertension, diabetes mellitus, high TG and low HDL-C, at the same time. Logistic regression analysis and receiver operating characteristic (ROC) curve analysis were employed to further explore the relationships. Results: The overall prevalence of CRFC among aged 35 and older population in Tibet and Xinjiang areas was 9.78%. BFP and VFI were divided into four groups by quartile. After adjustment for age, gender, race, cigarette smoking, alcohol consumption, education attainments, and altitude of residence, ORs of CRFC seemed to have increased with BFP and VFI. Compared with people having BFP of 5.0%-27.0%, the OR(95% CI) were 1.15(0.86-1.54), 1.48(1.05-2.07) and 1.72(1.10-2.68) for the ones who presented 27.1%-31.7%, 31.8%-36.6% and 36.7%-50.0% of BFP. Compared to people of having 1-6 of VFI, with OR (95%CI) as 1.20(0.81-1.79), 1.91(1.30-2.80) and 3.91(2.64-5.77) for the ones having 7-9, 10-13 and 14-30 of VFI. Areas under the curve (AUC) of CRFC appeared as 0.55 for BFP and 0.70 for VFI, respectively, with statistically significant difference (P<0.01). Conclusion: Both BFP and VFI levels were closely associated with CRFC while VFI seemed to have a better predictive value than the BFP.

Abstract
Objective: To explore the correlation between clinical symptoms of patients with obsessive-compulsive disorder (OCD) and the activation pattern of brain neurons at resting. Methods: A total of 26 patients diagnosed with fist-episode OCD were selected and underwent functional magnetic resonance imaging (fMRI) scanning at resting state. The fMRI data were processed by statistical parametric mapping (SPM8), Data Processing Assistant for Resting-State fMRI Analysis Toolkit (DPARSFA), and Resting State fMRI Data Analysis Toolkit (REST) software. With age as concomitant variable, Pearson Correlation Analysis was adopted to study the correlation between clinical symptoms (obsessive thoughts and compulsive behavior) of patients and their regional homogeneity ( ReHo) values of whole brain. Results: The positive correlation between obsessive thoughts score of patients with OCD and ReHo value lied in insular_L, insular_R, cerebellum_L, cerebellum_R, calcarine_L, cuneus_L. The negative correlation between obsessive thoughts score of patients with OCD and ReHo value lied in thalamus_L, precuneus_L, caudate_L, cingulum_R, frontal_R. The positive correlation between compulsive behavior score of patients with OCD and ReHo value lied in temporal_L, frontal_inf_orb_l, frontal_inf_orb_R, frontal_mid_L, precentral_R. The negative correlation between compulsive behavior score of patients with OCD and ReHo value lied in cingulum-L, cingulum-R, caudate_L. Conclusion: Different obsessive-compulsive symptoms has different image foundation, and the dysfunction of cingulate has a major impact on the incidence of both obsessive thoughts and compulsive behavior of OCD patients.

Abstract
OBJECTIVE To explore the protective effects of Tibetan medicine Zuo-Mu-A Decoction (, ZMAD) on the blood parameters and myocardium of high altitude polycythemia (HAPC) model rats. METHODS Forty male Wistar rats were randomly divided into 4 groups by a random number table, including the normal, model, Rhodiola rosea L. (RRL) and ZMAD groups (10 in each group). Every group was raised in Lhasa to create a HAPC model except the normal group. After modeling, rats in the RRL and the ZMAD groups were administered intragastrically with RRL (20 mL/kg) and ZMAD (7.5 mL/kg) once a day for 2 months, respectively; for the normal and the model groups, 5 mL of distilled water was administered intragastrically instead of decoction. Then routine blood and hematologic rheology parameters were taken, levels of erythropoietin and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were tested, and ultrastructural change in the left ventricular myocardium was observed using transmission electron microscopy. RESULTS Compared with the model group, ZMAD significantly reduced the red blood cell count, hemoglobin levels, whole blood viscosity at low/middle shear rates, plasma viscosity, erythrocyte electrophoretic time, erythropoietin and 8-OHdG levels, and also increased the erythrocyte deformation index (P<0.05). There was no difference in all results between the RRL and the ZMAD groups. The cardiac muscle fibers were well-protected, mitochondrial matrix swelled mildly and ultrastructure changes were less prominent in the ZMAD group compared with the model group. CONCLUSION ZMAD has significant protective effects on the blood parameters against HAPC, and also has the beneficial effect in protecting against myocardial injury.

Abstract
We aimed to evaluate dendritic cell (DC) tumor vaccines for preventing liver cancer recurrence and metastasis. DCs were induced from mononuclear cells in the peripheral blood with recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) and recombinant human interleukin 4 (rhIL-4), followed by sensitization with lysis of autologous liver cancer cells. One hundred and sixty patients with hepatocellular carcinoma were randomly divided into two groups of 80. One group was treated postoperatively with six cycles of the DC tumor vaccine. The other group was treated postoperatively with six cycles of FOLFOX 6, beginning 1 week after surgery. After treatment with DC tumor vaccines, the levels of CD3+, CD4+, and CD8+, the ratio of CD4+ to CD8+ DC, and the serum levels of IL-12 and IFN-γ were significantly increased both in comparison to the pre-treatment levels (P < 0.001) and to the chemotherapy group (P < 0.001). After a postoperative follow-up of 18 months, the metastatic recurrence rate in the DC tumor vaccine group was significantly lower than that in the chemotherapy group (17.50 vs 48.75%, P < 0.005), and the survival rate of the patients in the DC tumor vaccine group was higher than that of the chemotherapy treatment group (86.25 vs 52.50%, P < 0.005). Treatment with DC tumor vaccines was safe and feasible. It can enhance the immunity of the patients, reduce the rates of metastasis and recurrence, and improve survival rates. This is a promising treatment for the prevention of postoperative recurrence in patients with liver cancer.

Abstract
The effect of tree diversity on productivity in subtropical forests in China is poorly understood. We investigated the biomasses of trees, understory vegetation, coarse roots, and fine roots with varying proportions of Pinus massoniana, mixed with other tree species in stands of the same age, to examine the effects of tree diversity. With an increase of P. massoniana proportion, the tree and understory biomasses increased at first, and then gradually decreased. As expected, the biomass of fine roots decreased with soil depth. Stands with 40 to 60% P. massoniana had the highest biomass, whereas stands with <20% P. massoniana had the least biomass. Stands with <20% P. massoniana had the least understory biomass, whereas those with 20 to 40% Masson pine had the least fine root biomass.

Abstract
Oxygen is one of the critical determinants for normal embryonic and fetal development. In avian embryos, lack of oxygen will lead to high fetal mortality, heteroplasia, and cardiovascular dysfunction. Tibetan chicken is a breed native to Tibet that could survive and keep higher hatchability regardless of negative effects of hypoxia. Generally, adaptive animals in high altitudes are characterized by higher hemoglobin concentrations and oxygen affinity. In the present study, the capacity of oxygen supply in late chick embryo (including d 17, 19, and 21) was compared between Tibetan chicken and a lowland breed, Dwarf White chicken, by determining the hemoglobin concentrations and oxygen equilibrium curves in both hypoxic (13% O(2)) and normoxic (21% O(2)) conditions. The results showed that a higher level of hemoglobin concentration was induced by hypoxia in Tibetan chicken embryos, and the hemoglobin could perform with better cooperativity and deliver oxygen to tissues more easily. Further investigation revealed that the carbonic anhydrase II mRNA in red blood cells of Tibetan chicken was increasingly induced to a higher level in hypoxia than that of the lowland breed. These results suggested that the stronger capacity of oxygen dissociation was an important characteristic of Tibetan chicken embryo to survive in hypoxia and the upregulating mode of carbonic anhydrase II mRNA might assist this dissociation. Therefore, for avian at high altitudes, the efficient dissociation of oxygen might reveal another aspect associated with the hypoxia adaptability.

Abstract
In order to study the biological significance of alpha-mannosidase Man2c1, hMan2c1 transgenic mice were developed. In 113 F0 mice, eight were found to be genomic PCR positive for hMan2c1; 9/20 (45%) F1 mice, 16/21 (76.2%) F2 mice, and 12/14 (85.7%) F3 mice were genomic PCR positive for hMan2c1. RT-PCR demonstrated hMan2c1 mRNA transcription in four of eight transgenic lines. Enzymatic activity on p-nitrophenyl-alpha-D: -mannopyranoside was enhanced in 35# and 54# transgenic mice and real-time RT-PCR showed hMan2c1 mRNA expression in these mice. Reduced Con A binding to splenocytes implied N-glycosylation modification of host proteins by hMan2c1 transgene. hMan2c1 transgene promoted growth, invasion, and metastasis to lung of implanted hepatoma H22 and sarcoma S180. The average weights of H22 and S180 tumors were 3.98 +/- 1.62, 3.29 +/- 0.76, 1.69 +/- 1.09, and 3.19 +/- 0.44, 2.72 +/- 1.38, 0.97 +/- 0.41 g for 35#, 54# transgenic mice and wild type mice (W), respectively, (35# or 54# versus W, paired t-test, P < 0.05). In 35# and 54# mice 5/10 and 3/10 showed lung metastasis of H22 tumor in contrast with 1/10 in W mice. In 35# and 54# mice 1/6 and 2/6 showed lung metastasis of S180 tumor in contrast with 0/6 in W mice. The possible mechanism of the promotion was explored on both humoral and cellular immunity. Reduced antibody response to BSA was observed in transgenic mice, suggesting that specific antibody response to tumor antigens might be suppressed by hMan2c1 transgene. However, NK cytotoxicity in splenocytes was not affected by the transgene.
