ABSTRACT
Objective:To investigate the clinical efficacy of da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer.Methods:The retrospec-tive cohort study was conducted. The clinicopathological data of 102 patients with middle and low rectal cancer who were admitted to the Affiliated Hospital of Xuzhou Medical University from August 2020 to June 2021 were collected. There were 62 males and 40 females, aged (53±12)years. Of the 102 patients, 51 cases undergoing da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer were divided into the robotic group and 51 cases undergoing laparoscopic anterior resection of rectal cancer were divided into the laparoscopic group. Observa-tion indicators: (1) treatment; (2) postoperative pathological examination; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Repeated measurement data were analyzed using the repeated ANOVA. Results:(1) Treatment. All patients of the two groups under-went radical resection of rectal cancer successfully, and none of patient with intraoperative blood transfusion, conversion to open surgery, and death within 30 days after surgery. The operation time, volume of intraoperative blood loss, number of lymph nodes dissected, time to postoperative first flatus, time to postoperative first liquid food intake, time to postoperative catheter removal, cases with postoperative pain grading as grade 1, grade 2, grade 3, grade 4, cost of treatment were (170±12)minutes, (73±50)mL, 23±6, (35.1±9.4)hours, (2.1±0.8)days, (2.9±2.7)days, 13, 15, 17, 6, (7.1±4.5) ten thousand yuan in patients of the robotic group, versus (153±22)minutes, (119±66) mL, 15±4, (40.7±1.9)hours, (2.9±0.4)days, (5.3±2.1)days, 6, 7, 26, 12, (6.7±1.6) ten thousand yuan in patients of the laparoscopic group, showing significant differences in the above indicators between the two groups ( t=6.79, -4.46,20.09, -3.01, -5.54, -16.69, Z=-2.87, t=4.22, P<0.05). (2) Postoperative patho-logical examination. The tumor diameter, length of specimen resected, distance of upper resection margin to tumor, distance of lower resection margin to tumor, cases with mesorectal specimens as integrity and mostly integrity, cases with tumor differentiation as high differentiation, moderate differentiation, low differentiation, cases with postoperative TNM staging as stage Ⅰ, stage Ⅱ, stage Ⅲ were (3.8±1.1)cm, (18.7±3.2)cm, (11.8±3.6)cm, (2.7±0.8)cm, 48, 3, 4, 41, 6, 6, 17, 28 in patients of the robotic group, versus (3.7±1.0)cm, (18.3±2.8)cm, (10.2±2.7)cm, (2.5±0.6)cm, 46, 5, 6, 39, 6, 5,20, 26 in patients of the laparoscopic group, showing no significant difference in the above indicators between the two groups ( t=1.72, 1.29, 1.64, 1.11, χ2=0.14, Z=-0.42, -0.26, P>0.05). Cases with positive circumferential margin and cases with destruction of mesentery was 0 and 0 in patients of the robotic group, versus 1 and 1 in patients of the laparoscopic group, showing no significant difference in the above indicators between the two groups ( P>0.05). (3) Follow-up. All patients in the two groups were followed up for 12 months after surgery and none of patient had postoperative local recurrence and distant metastasis of tumors. The anal incontinence score, low anterior resection syndrome score, international prostate symptom score, night urination score, international index of erectile score, female sexual function index score in patients of the robotic group were 0, 12.25±1.08, 4.43±0.33, 0.49±0.09, 24.07±2.75, 65.84±1.79 before surgery and 1.34±0.11, 18.11±3.54, 4.03±0.26, 1.08±0.28, 22.63±2.03, 38.57±6.13 at postoperative 12 months, respectively. The above indicators in patients of the laparoscopic group were 0, 12.60±1.11, 4.56±0.36, 0.46±0.07, 23.11±2.77, 66.31±1.73 before surgery and 1.99±1.33,20.85±6.19, 6.43±1.78, 2.27±0.23, 21.00±2.73, 27.62±8.20 at postoperative 12 months, respectively. There were significant differences in the above indicators between the two groups ( P<0.05). Conclusions:The oncological effects of da Vinci Xi surgical system assisted programmed six-hole method anterior resection of rectal cancer and lapa-roscopic anterior resection of rectal cancer are comparable. However, robotic surgery is superior to laparoscopic surgery in terms of intraoperative bleeding, lymph node dissection, gastrointestinal function recovery, and pelvic autonomic nerve protection.
ABSTRACT
Objective:To analyze the epidemiological and clinical features of acute and chronic brucellosis in minors from 2016 to 2020 in Heilongjiang, and to provide evidence for diagnosis, prevention and treatment of brucellosis in minors.Methods:A retrospective analysis of the medical records of 150 hospitalized patients with brucellosis in minors from January 2016 to December 2020 was conducted in Beidahuang Industry Group General Hospital. According to clinical classification, 125 cases were acute patients and 25 cases were chronic patients. At the same time, 40 outpatient physical examination persons were selected as control group. Epidemiological features, clinical presentation and misdiagnosis of acute and chronic brucellosis in minors were analyzed and compared. The results of routine blood test, liver function test, myocardial enzyme test, whole blood C-reactive protein (CRP) and blood culture were analyzed and compared among acute group, chronic group and control group.Results:From 2016 to 2020, the proportion of brucellosis in minors was 3.26% (37/1 136), 2.50% (28/1 119), 3.31% (36/1 088), 2.80% (35/1 250) and 2.00% (14/701), respectively. In acute and chronic brucellosis, the ratios of male to female were 1.66 ∶ 1.00 (78/47) and 1.27 ∶ 1.00 (14/11); the incidence rate was highest in school age [35.2% (44/125), 44.0% (11/25)] and lowest in infant [2.4% (3/125), 0 (0/25)]; the disease were most common in March and June [52.8% (66/125), 44.0% (11/25)]; the more distribution was in Qiqihar [19.2% (24/125), 28.0% (7/25)], and the most susceptible factor was contact with cattle and sheep [89.6% (112/125), 96.0% (24/25)]. In acute group, there was 1 case of lactation infection. There were 32 cases [25.6% (32/125)] and 8 cases [32.0% (8/25)] with four typical symptoms in the two groups. High fever was the most common type in acute group [41.2% (47/114)]. Knee pain was the most common type [50.0% (36/72), 60.0% (12/20)] in both groups. The incidence of musculoskeletal pain in acute group was higher than that in chronic group (χ 2 = 4.57, P = 0.033). The rates of fatigue and joint pain in chronic group were higher than those in acute group (χ 2 = 4.49, 4.41, P < 0.05). Totally 57.3% (86/150) of patients with brucellosis were misdiagnosed as other diseases [49.3% (74/150)] in acute group and 8.0% (12/150) in chronic group] and colds were the most common, accounting for 38.0% (57/150). The positive rate of blood culture in acute group (48 cases, 38.4%) was significantly higher than that in chronic group (4 cases, 16.0%, χ 2 = 4.62, P = 0.038). Compared with control group, the levels of monocyte, alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP), lactate dehydrogenase(LDH), hydroxybutyrate dehydrogenase(HBDH), creatine kinase isoenzyme(CK-MB), hemoglobin (HGB), mean corpuscular volume(MCV), mean corpuscular hemoglobin (MCH), mean corpuscular-hemoglobin concentration (MCHC), total protein (TP), albumin (ALB) in acute group and chronic group were significantly different ( P < 0.05); compared with the chronic group, CRP and LDH increased, the differences were statistically significant ( P < 0.01). Conclusions:The epidemiological characteristics and clinical symptoms of acute and chronic brucellosis in minors in Heilongjiang are different. Monocyte, erythrocyte, transaminase, TP, ALB and myocardial enzyme are changed significantly, it needs to be monitored regularly and given certain protective measures.
ABSTRACT
The medical data processed and analyzed in clinical research often contain a large number of personal information. Therefore, researchers should pay attention to the safety management of medical data during clinical research. The Data Security Law of People's Republic of China and the Personal Information Protection Law of People's Republic of China implemented on 1 st September and 1 st November 2021 respectively establish legal basis for data security and personal information protection and point out the direction for medical data security, which indicate that data governance has entered the 'strong regulatory era'. In the process of medical data collection and application of clinical research, respecting and protecting the privacy and safety of patients, ensuring the quality of medical data, safely managing medical data and carrying out high-quality clinical research will be an important test for the collection and application of clinical scientific research data under the new legal background.

ABSTRACT
Objective:To observe the effect of local retinal laser photocoagulation (local photocoagulation) on Coats disease.Methods:A retrospective clinical study. From January 1, 2006 to August 1, 2020, 48 patients (48 eyes) who were diagnosed as Coats disease and received focal photocoagulation at The Eye Hospital Affiliated to Wenzhou Medical University were included in the study. Among them, there were 40 males (40 eyes) and 8 females (8 eyes). The average age was 32.46±22.41 years old. Nine eyes were in stage 2A, and 39 eyes were in stage 2B. All affected eyes underwent best corrected visual acuity (BCVA), color fundus photography and fluorescein fundus angiography (FFA).The BCVA was carried out using a standard logarithmic visual acuity chart, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. According to age, patients were divided into the adolescent group (age≤ 20 years old) and the adult group (age> 21 years old), with 18 eyes in 18 cases and 30 eyes in 30 cases, respectively. In the adolescent group, 18 eyes of 18 cases were all male; the average age was 11.17±3.31 years; the average logMAR BCVA was 0.83±0.60. Among the 30 patients in the adult group, 22 patients were male and 8 patients were female. the average age was 49.26±15.26 years old; the average logMAR BCVA was 0.82±0.59. All the affected eyes were treated with focal photocoagulation. Laser parameters were as followed: wavelength 577 nm, spot diameter 500 μm, exposure time 0.5 to 0.7 s, spot intensity level Ⅲ. FFA was FFA was performed 3 to 4 months after the first laser photocoagulation, and laser treatment was repeated as needed. The average follow-up after first treatment was 36.88±36.92 months. The changes in BCVA, abnormal blood vessels in the fundus, and hard exudation were observed.Results:Among 48 eyes, 36 eyes (75.00%, 36/48) received multiple local photocoagulation treatments. At the last follow-up, 36 eyes (75.00%, 36/48) had an improved or stable vision, and 17 eyes (35.42%, 17/48) had BCVA ≤ 0.32 logMAR units (≥ 0.5). The average logMAR BCVA of eyes in the adolescent group was 0.66±0.54, which was higher than the baseline, but the difference was not statistically significant ( Z=-1.126, P=0.260). The average logMAR BCVA of the eyes in the adult group was 0.96±0.79, which was lower than the baseline, but the difference was not statistically significant ( Z=-0.482, P=0.630). Among 48 eyes, abnormal blood vessels were completely or partially occluded in 42 eyes (87.50%, 42/48); of which, 29 eyes were completely occluded (60.42%, 29/48), and 13 eyes were partially occluded (27.08%, 13/48)). The hard exudation at macula or peripheral retina were completely absorbed or obviously absorbed in 40 eyes (83.33%, 40/48); among them, the complete and obvious absorption were 11 (22.92%, 11/48) and 29 (60.42%, 29/48) eyes. Conclusion:The treatment of focal photocoagulation with a larger spot, long exposure and weak level Ⅲ spot can effectively seal abnormal blood vessels in the eyes of Coats disease,reduce hard exudation and improve or stabilize vision.
ABSTRACT
Objective:Cholangiocarcinoma (CCA) is a malignant tumor derived from bile duct epithelial cells with extremely poor prognosis. The Hippo-Yes-associated protein (YAP)/transcription activator with PDZ binding motif (TAZ) signaling plays a critical role in cancer stem cell biology. Previous studies have shown that the positive expression of YAP/TAZ in CCA predicts larger tumor size and unfavorable clinical outcomes. We aim to evaluate the prognostic value of YAP/TAZ detection in CCA patients.Methods:CCA patients who underwent radical resection were retrospectively analyzed at our institution from January 2011 to June 2016. Postoperative pathological specimens were scored by YAP/TAZ immunohistochemical staining. The prognostic value of YAP/TAZ was analyzed by multivariate Cox-proportional hazards model.Results:A total of 91 CCA patients were enrolled. During a median follow-up time of 11.0 months, 69.2% patients relapsed and 45.1% died. The median OS and DFS were 10.7 months and 8.8 months respectively. The YAP/TAZ dual positive patients owned a worse TNM stage ( P=0.015), poorer tissue differentiation ( P=0.007), and a higher CA199 than those in negative patients. Multivariate Cox analysis identified that YAP/TAZ dual positivity as a significant factor predicted poorer OS ( P=0.010) and DFS ( P=0.028) in CCA patients after radical resection. In subgroup analysis, YAP/TAZ combination also significantly predicted OS ( P=0.044) and DFS ( P=0.043) in CCA patients with positive lymphatic metastasis and/or surgical margin who required adjuvant therapy. Conclusions:YAP/TAZ positivity is an independent predictive factor for survival in CCA patients after radical resectiony.
ABSTRACT
Objective:To analyze the clincial characteristics and laboratory findings of patients with neurobrucellosis (NB).Methods:Using retrospective analysis, clinical diagnosed patients with NB from June 2016 to February 2019 in Heilongjiang Agricultural Reclamation Bureau General Hospital were selected to analyze the general characteristics, clinical symptoms, laboratory examination results [white blood cell (WBC), hemoglobin(Hb), c-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), cerebrospinal fluid routine and biochemical, serum tube agglutination test (SAT), blood culture and cerebrospinal fluid culture of Brucella] , diagnosis and treatment effect. Results:A total of 25 patients were diagnosed with NB, including 19 males and 6 females, with an average age of (41.7 ± 14.2) years old, ranged from 11 to 70 years old. The main clinical symptoms were fever, headache, joint pain, vomiting and sweating, which accounted for 92.0% (23/25), 88.0% (22/25), 76.0% (19/25), 64.0% (16/25), and 64.0% (16/25), respectively. Positive neck ankylosis and mumbness of lowerlimbs were both 9 cases (36.0%), and mental disorders were 7 cases (28.0%). In 25 patients with NB, the WBC increased in 5 cases (20.0%), Hb decreased in 4 cases (16.0%), CRP increased in 13 cases (52.0%), ALT and AST both increased in 6 cases (24.0%), TP decreased in 21 cases (84.0%); SAT was positive in 25 cases (100.0%), cerebrospinal fluid SAT positive in 7 cases (28.0%); and blood culture was positive in 2 cases (8.0%). Cerebrospinal fluid changes were mainly manifested in 14 cases (56.0%) of chloride reduction, 13 cases (52.0%) of gluose reduction and 19 cases (76.0%) of protein increase. In 25 patients with NB, 17 cases were treated with doxycycline + rifampicin + ceftriaxone, 7 cases with etimicin + rifampicin + ceftriaxone, and 1 case with doxycycline + rifampicin + piperacillin sulbactam. After 6 to 12 months follow-up, 21 cases recovered well, whereas mild sequelae were observed in 4 patients.Conclusion:Clinical features of NB are hetorogeneous, and nerurological symptoms and cerebrospinal fluid examination are of great value in the diagnosis of NB.

Abstract@#Physical activity promotes the physical and mental health of children and adolescents, and a growing body of research has demonstrated the positive effects of physical exercise, including better academic performance. This review presents a retrospective analysis of the existing literature in order to explore the relationship between physical activity patterns and academic performance in children and adolescents. This study analyzes the impact of differences in the duration, frequency, intensity, and type of physical activity on the academic performance of children and adolescents, which provides a basis for improving the quality and effect of such physical activities. High-quality evidence supports the view that long-term, high-frequency, aerobic physical activities of moderate-to-vigorous intensity have a positive impact on children and adolescents’ academic performance. This study provides a reference to help families, schools, and society to scientifically and rationally promote physical activity among children and adolescents.
ABSTRACT
Objective@#To analyze the epidemiologic and clinical features of preschool children with brucellosis, and improve awareness of brucellosis and level of diagnosis.@*Methods@#In-patients treated for brucellosis in preschool children from December 2016 to November 2018 in Heilongjiang Agricultural Reclamation Bureau General Hospital were retrospectively analyzed for epidemiology, clinical feature, laboratory data, treatment and prognosis.@*Results@#There were 29 males and 16 females among the 45 preschool children brucellosis cases, with an average age of (3.7 ± 1.6) years old, ranged from 6 months to 6 years old. The patients of > 3-6 years old of age had the highest incidence (64.44%, 29/45). The patients were mainly rural residents (97.78%, 44/45). The onset time was mainly from March to June of the year (46.67%, 21/45). Clinical symptoms were mostly fever and joint pain, which accounted for 97.78% (44/45) and 57.78% (26/45), respectively. And lymph node enlargement and hepatosplenomegaly were also commonly seen, which accounted for 42.22% (19/45) and 35.56% (16/45). After treatment, the test results of patients with alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine kinase isoenzyme (CK-MB), α-hydroxybutyrate dehydrogenase (HBDH) and lactate dehydrogenase (LDH) were compared with those of before the treatment, the differences were statistically significant (t=4.774, 2.970, 2.229, 5.664, 5.805, P < 0.05). Before the treatment, 36 patients (80.00%, 36/45) had positive blood culture, which turned negative after the treatment.@*Conclusions@#The epidemiologic and clinical features of preschool children with brucellosis are not typical. In the epidemic area of the disease and multiple seasons, for children with unexplained fever, the clinician should inquire about the epidemiological history and combine the clinical feature, consider the possibility of brucellosis, and strive for early diagnosis and treatment.
ABSTRACT
Medical ethics has a long history and rich connotations.It has developed from the simple "medical morality" of ancient times to the modem medical ethics.The basic principles of medical ethics include autonomy,non-maleficence,beneficence,justice,and so on.Researchers often conduct clinical researches in the balance between achievements and ethical norms.Clinical researchers of surgery should have a deep understanding of medical ethical principles and strictly abide by medical ethics.Ethics committee should strictly perform their duties and play the role of inspection and supervision.Modem medical knowledges should be popularized throughout the society to make clinical research correctly understood.Adhering principles of ethics first,people orientation and cooperation practice,with patients' benefit as evaluation criteria,balance of surgical "Dao" and "Shu" can be achieved.
ABSTRACT
Objective The purpose of this study was to evaluate the degree of skin thickening of patients with systemic sclerosis (SSc) by high-frequecy ultrasound,as well as the value of ultrasound.Methods Thirty-one patients with SSc and 31 age-matched and sex-matched healthy control subjects were enrolled.Skin thickness,modified Rodnan skin score (mRss),disease activity index (DA1) and other clinical parameters within and between groups were compared using SPSS 21 software.Student's t test,x2 test or nonparametric testing was performed to compare between groups.The Pearson or Spearman methods were used to test correlation.Sensitivity and specificity of skin thickness detection by high-frequecy ultrasound were evaluated by using receiver operating characteristic (ROC) curve analysis.Results Total thickness of skin (TST) of patientswith SSc were positively correlated to the total mRss (r=0.416,P=0.020) and DAI (r=0.436,P=0.014).The skin thickness of patients with mRss 0,1,2 was higher than CNT [1.45(0.60),1.70(0.30) mm,1.60 (0.30) mm vs 1.30 (0.35) mm,Z=-3.242,-6.577,-5.090,P＜0.01].The cut-off value of TST used as the evaluation of skin change was 7.4 mm by ROC curve analysis,and the sensitivity and specificity of them was 77.40％ and 87.10％ respectively,and patients with thickened skin were more likely to suffer interstitial lung disease (ILD) (16 vs 1,x2=26.004,P=0.014),higher mRss [10(6) vs 4(5),Z=-2.499,P=0.031],DAI [(5.2±2.4) vs (2.3±1.7),t=-3.104,P＜0.01)] and CRP [(8.60 (10.48) mg/L vs 3.52 (4.93) mg/L,Z=-2.276,P=0.038].Conclusion US combined with mRss are helpful to evaluate the changes of skin and disease activity of patients in SSc.US can identify the early and subclinical skin involvement that may precede mRss,providing a more reliable tool for diagnosis,treat efficacy and prediction of organ damage.

ABSTRACT
Objective To explore how leptin affects RA,especially those with joint erosion.Methods The study recruited 48 consecutive patients with RA (14 patients with knee joint effusion) and 23 age and sex matched healthy people.RA patients were grouped into low and moderate activity group [2.6＜28-joint disease activity score (DAS28) ≤5.1,n =5] and high activity group (DAS28 ＞5.1,n =43) according DAS28-ESR;Meanwhile,they were grouped into bone erosive group (n=20) and non-erosive group (n=28) according to X-ray of both hands.Demographic data of RA patients were recorded.ELISA was applied to assess leptin and a disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS4) in serum and synovial fluid of RA group.Sharp/van der Heijde scores were used to assess bone erosion and joint space narrowing.Leptin and ADAMTS4 from serum and synovial fluid were compared between different groups using t test,Rank sum test,Chi-square test and Analysis of Variance,and we did Pearson and Spearman's Corre-lation analyses between these values and clinical features,lab indicators and radiological scores.Moreover,we did single factor and logistic regression analyses,which facilitated screening risk factors of joint destruction.Results Serum leptin in RA group was significantly higher than that of the control group [8.06(6.24) ng/ml vs 4.62(7.13),Z=-2.113,P=0.035],and leptin was positively correlated with Shar/van der Heijde score (r=0.347,P=0.016).Serum leptin in erosive RA patients was higher than that of the non-erosive patients (Z=-2.070,P=0.038),and there was a positive correlation between leptin and ADAMTS4 only in synovial fluid of RA patients with erosion (r=0.900,P=0.037).It was found in logistic regression results that RA patients with more tender joint counts and elevated leptin were more likely to develop bone erosion [OR=1.229,95％CI (1.007,1.500),P=0.043;OR=1.159,95％CI (1.015,1.324),P=0.030].Conclusion Leptin participates RA joint destruction probably by modulating expression of ADAMTS4.Leptin and tender joint count are independent risk factors for RA with joint destruction.

ABSTRACT
Many risk factors lead to hypohepatia and hepatic failure,causing people suffering from end-stage liver disease.The conventional treatment for end-stage liver disease is not good enough.Orthotopic liver transplantation is effective.However,the high cost,lack of liver source,immune rejection and other factors limit the large-scale clinical application.Thus,cell therapy is a good option.Studies on common cell sources for the treatment of liver disease and the induction of hepatocytes by embryonic stem cells or pluripotent stem cells have made progress.With the development of stem cell technology,cell transplantation has become a new option,which brings hope to people with end-stage liver diseasetransplantation has become a new option.It brings hope to people with endstage liver disease.

ABSTRACT
Objective@#To analyze the association between food intake and the serum total cholesterol(TC) level in adult Chinese population.@*Methods@#This study included apparent healthy residents aged between 20 and 70 years who participated in the eighth round of China Health and Nutrition Study (CHNS) in 9 regions of China including Liaoning, Helongjiang, Shandong, Jiangsu, Henan, Hunan, Hubei, Guizhou provinces and Guangxi Zhuang Autonomous Region in 2009. The association between the serum TC level and the diet and other related factors were analyzed.@*Results@#(1) Linear trend test showed that age, body mass index, waist circumference, systolic and diastolic blood pressure were positively related with serum TC level in 20-45 and 46-70 years old male and female (all P<0.01), while physical activity level was negatively related with serum TC level in 20-45 and 46-70 years old male and 46-70 years old female (all P<0.01). (2) Multivariate linear regression analysis showed that livestock meat intake was positively related with serum TC level in following populations: 20-45 years old male, β=0.133, P<0.001; 46-70 years old male, β=0.102, P=0.001; 20-45 years old male, β=0.065, P=0.041; years old female, β=0.059, P=0.045. Vegetable oil intake was negatively related with serum TC level in 20-45 years old male (β=-0.071, P=0.021). Saturated fat intake was positively related with serum TC level in 46-70 years old female (β=0.084, P=0.019). Total dietary cholesterol intake was positively related with serum TC level in male (20-45 years old, β=0.067, P=0.021; 46-70 years old, β=0.070, P=0.012), but not in female (20-45 years old, β=0.007, P=0.809; 46-70 years old, β=0.038, P=0.144). Cholesterol intake from livestock meat was positively related with serum TC level in male (20-45 years old, β=0.156, P<0.001; 46-70 years old, β=0.099, P=0.001), and positively related with serum TC level in 46-70 years old female (β=0.063, P=0.028). Cholesterol intake from egg was positively related with serum TC level in 46-70 years old male (β=0.056, P=0.032).@*Conclusions@#Age, body mass index, waist circumference, blood pressure, blood pressure, and physical activity level are related with serum TC level. Cholesterol intake from livestock meat was the main food source that related with serum TC level, and the serum TC increases at a relatively small level after intake of total dietary cholesterol.
