Association between Serum Uric Acid to HDL-Cholesterol Ratio and Nonalcoholic Fatty Liver Disease Risk among Chinese Adults / 生物医学与环境科学（英文）

OBJECTIVE@#The aim of this case-control study was to explore the association between serum uric acid to high density lipoprotein cholesterol ratio (UHR) and the risk of nonalcoholic fatty liver disease (NAFLD) in Chinese adults.@*METHODS@#A total of 636 patients with NAFLD and 754 controls were enrolled from the Affiliated Hospital of Qingdao University, China, between January and December 2016. All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.@*RESULTS@#The multivariable adjusted odds ratio (95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888 (2.324-6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index (BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.@*CONCLUSION@#UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.

Study on the antipyretic mechanism of large pushing Tianheshui for young rabbits with endotoxin-induced fever / 针灸推拿医学（英文版）

Objective:To observe the effect of large pushing Tianheshui manipulation intervention on the body temperature of young rabbits with endotoxin-induced fever and discuss its antipyretic mechanism.Methods:Thirty-two young rabbits meeting the standards were selected from 40 ordinary young male New Zealand rabbits after being adapted for 7 d,and randomly divided into a normal group,a model group,a large pushing Tianheshui group,and an ibuprofen group according to the random number table method,with 8 rabbits in each group.Rabbits in the model group,the large pushing Tianheshui group,and the ibuprofen group were subjected to preparing the endotoxin-induced fever model by intravenous lipopolysaccharide from the marginal ear vein.Rabbits in the large pushing Tianheshui group received Tuina(Chinese therapeutic massage)manipulation intervention 1.5 h and 2.5 h after modeling,respectively.Rabbits in the ibuprofen group were intragastrically given ibuprofen suspension 1.5 h after modeling.The dynamic changes in body temperature were observed for the young rabbits after fever modeling.Enzyme-linked immunosorbent assay was used to determine the content changes in positive mediators of hypothalamic body temperature,including prostaglandin(PG)E2 and cyclic adenosine monophosphate(cAMP),as well as negative mediators of hypothalamic body temperature,including arginine vasopressin(AVP)and α-melanocyte stimulating hormone(α-MSH).Results:The body temperature of the young rabbits in the model group was significantly higher than that in the normal group at 0.5-4.0 h,5.0 h,and 5.5 h after modeling(P＜0.01),showing two obvious fever peaks in the model group at 1.5 h and 3.0 h after modeling,respectively,with the highest peak at 1.5 h.Compared with the model group,body temperatures of the large pushing Tianheshui group and the ibuprofen group decreased significantly after 0.5 h of intervention(P＜0.05).Compared with the normal group,the contents of PGE2 and cAMP were significantly increased(P＜0.05),and the contents of AVP and α-MSH were significantly decreased(P＜0.01)in the hypothalamus of the model group.Compared with the model group,the contents of PGE2 and cAMP were significantly decreased(P＜0.01),and the levels of AVP and α-MSH were significantly increased(P＜0.01)in the hypothalamus in the large pushing Tianheshui group and the ibuprofen group.There were no significant differences in the PGE2,cAMP,AVP,and α-MSH contents in the hypothalamus between the ibuprofen group and the large pushing Tianheshui group(P＞0.05).Conclusion:Large pushing Tianheshui manipulation has a significant antipyretic effect on endotoxin-induced fever in young rabbits.The mechanism may be related to inhibiting the positive regulators(PGE2 and cAMP)and promoting the negative regulators(AVP and α-MSH)of hypothalamic control of body temperature.

Observation indica-tors: (1) patients conditions after being treatment with open abdomen technique; (2) analysis of clinical characteristics in patients with different treatment outcomes; (3) changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes; (4) influencing factors for prognosis of patients. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or the continuity correction chi-square test. Repeated measurement data were analyzed using the repeated ANOVA. Spearman correlation analysis was used for correlation analyses. The COX regression model was used for univariate analysis and COX regression model with forward regression was used for multivariate analysis. Results:(1) Patients conditions after being treatment with open abdomen technique. Intra-abdominal pressure, oxygena-tion index, levels of lactic acid and sequential organ failure score of the 186 patients were (23.3±1.9)mmHg (1 mmHg=0.133 kPa), (121±24)mmHg, (5.0±3.4)mmol/L and 10.4±3.6 before the treatment with open abdomen technique and (11.2±2.9)mmHg, (222±38)mmHg, (3.2±2.1)mmol/L and 4.4±2.3 at postoperative 168 hours, showing significant differences in time effects before and after the treatment ( Ftime=855.26,208.50, 174.91,208.47, P<0.05). (2) Analysis of clinical characteristics in patients with different treatment outcomes. Of the 186 patients, 166 cases survived and were discharged, and 20 cases died during hospitalization. Age, sequential organ failure score, duration of ACS and levels of lactic acid during hospitalization before the treatment with open abdomen technique were (41±7)years, 9.4±3.4, 13(10,21)hours and (4.2±0.6)mmol/L in surviving patients, versus (45±6)years, 11.5±2.4, 65(39,84)hours and (5.2±0.5)mmol/L in dead patients, respectively, showing significant differences between them ( t=-2.10, -2.71, Z=-5.36, t=-7.16, P<0.05). Duration of postoperative acute gastro-intestinal injury, duration of continuous renal replacement therapy, time to liberation from mech-anical ventilation, duration of vasoactive drugs therapy, cases undergoing early abdominal closure, cases without intestinal fistula or with postoperative high-order intestinal fistula and low-order intestinal fistula during hospitalization after the treatment with open abdomen technique were 4(2,6)days, 4(3,7)days, 34(21,41)days, 3(2,6)days, 126, 131, 23, 12 in surviving patients, versus 13(10,17)days, 10(8,18)days, 0(0,3)days, 8(6,12)days, 1, 2, 15, 3 in dead patients, respectively, showing significant differences between them ( Z=-5.60, -3.75, -3.64, -3.06, χ2=41.43, 45.86, P<0.05). (3) Changing trend of the volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in patients with different treatment outcomes. The volume of urine output, levels of lactic acid, levels of enteral nutrient intake and the sequential organ failure score in surviving patients during hospitalization were (0.29±0.10)mL/(kg·h), (4.2±0.6)mmol/L, 0.0 kcal/(kg·d) and 9.4±3.4 before the treatment with open abdomen technique and (2.22±0.15)mL/(kg·h), (1.9±0.7)mmol/L, (20.7±2.9)kcal/(kg·d) and 3.7±2.2 at postoperative 168 hours. The above indicators in dead patients during hospitalization were (0.28±0.08)mL/(kg·h), (5.2±0.5)mmol/L, 0.0kcal/(kg·d) and 11.5±2.4 before the treatment with open abdomen technique and (0.28±0.09)mL/(kg·h), (7.7±0.8)mmol/L, (4.6±1.8)kcal/(kg·d) and 12.4±2.1 at postoperative 168 hours. There were significant differences in time effects in the above indicators in surviving patients and dead patients before and after the treatment with open abdomen technique ( Ftime=425.57, 188.59, 394.84, 37.52, P<0.05). There were interactive effects between the above indicators and the treatment outcome at different time points ( Finteraction=383.14, 233.04, 169.83, 36.61, P<0.05). There were signifi-cant differences in the change trends of the above indicators between the surviving patients and the dead patients during hospitalization ( Fgouprs=2 739.56, 877.98, 542.05, 240.85, P<0.05). (4) Influen-cing factors for prognosis of patients. Results of univariate analysis showed that age, sequential organ failure score, duration of ACS before surgery, procalcitonin, lactic acid, postoperative high-order intestinal fistula, abdominal hemorrhage, duration of postoperative acute gastrointestinal injury, duration of continuous renal replacement therapy, duration of vasoactive drugs therapy, early abdominal closure were related factors influencing prognosis of patients under-going treatment with open abdomen technique ( hazard ratio=1.07, 1.18, 1.39, 1.16, 8.25, 12.26, 2.83, 1.29, 1.56, 1.41, 0.02, 95% confidence interval as 1.00-1.15, 1.45-2.27, 1.22-1.57, 1.02-1.32, 1.75-38.90, 7.37-41.23, 1.16-6.93, 1.22-1.37, 1.23-1.99, 1.08-1.84, 0.00-0.16, P<0.05). Results of multivariate analysis showed that extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury were independent risk factors influencing prognosis of patients undergoing treatment with open abdomen technique ( hazard ratio=1.05, 7.95, 1.17, 95% confidence interval as 1.01-1.32, 2.05-30.87, 1.13-1.95, P<0.05) and early abdominal closure was an independent protective factor ( hazard ratio=0.10, 95% confidence interval as 0.01-0.89, P<0.05). Results of Spearman correlation analysis showed that duration of ACS was positively correlated with sequential organ failure score before surgery ( r=0.71, P<0.05). Conclusions:Open abdomen technique is effective for acute pancreatitis with ACS. Extended duration of ACS before surgery, postoperative high-order intestinal fistula and extended duration of postoperative acute gastrointestinal injury are independent risk factors for prognosis of patients during hospitalization and early abdominal closure is an independent protective factor.

The influence of duration of intra-abdominal hypertension on the prognosis of critically ill patients / 中华急诊医学杂志

Background:In the clinical setting, the effect of intra-abdominal hypertension on the human body is dependent on time, but its role is not yet clear.Objective:To investigate the effect of the duration of intra-abdominal hypertension (IAH) on the prognosis of critically ill patients.Methods:This prospective cohort study enrolled 256 IAH patients who were admitted to the Surgical ICU of 10 Grade A hospitals in Fujian Province from January 2018 to December 2020. The duration of IAH (DIAH) was obtained after monitoring IAP, and ICU length of stay, duration of mechanical ventilation, duration of continuous renal replacement therapy (CRRT) and average daily energy intake from enteral nutrition during ICU stay were observed and recorded. The correlation was analyzed by Spearman rank correlation. The patients were divided into the survival group and the death group according to their survival state at 60 days after enrollment. Thereafter, clinical characteristics between the two groups were compared. Multivariable logistic regression was used to study and validate the relationship between DIAH and 60-day mortality. The receiver operating characteristics (ROC) curve was established to evaluate the predictive abilities of DIAH on the mortality risk.Results:In critically ill patients, DIAH was positively correlated with duration of mechanical ventilation ( r=0.679, P<0.001), duration of CRRT ( r=0.541, P<0.001) and ICU length of stay ( r=0.794, P<0.001), respectively. In addition, there was a negative correlation between DIAH and average daily energy intake from enteral nutrition ( r=-0.669, P<0.001). After multivariable adjustment, DIAH was an independent risk factor for 60-day mortality in critically patients with IAH ( OR=1.05, 95% CI: 1.01-1.12; P = 0.012), and exhibited a linearity change trend relationship with mortality risk. The ROC curve analysis of DIAH showed that the area under ROC curve (AUC) was 0.825 (95% CI: 0.763~0.886, P<0.01). When the cut-off value was 16.5 days, the sensitivity was 78.4% and the specificity was 75.4%. Conclusions:DIAH is an important risk factor for prognosis in critically ill patients. Early identification and rapid intervention for the etiology of IAH should be performed to shorten DIAH.

Clinical efficacy of Tuina manipulations for lumbar disc herniation and its influence on posture-associated indicators / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.

Therapeutic observation of manipulation plus exercise therapy in treating upper crossed syndrome postures of primary school students / 针灸推拿医学（英文版）

Objective: To observe the therapeutic efficacy of sinew-bone balancing manipulation plus exercise therapy in treating postures of primary school students with upper crossed syndrome (UCS).Methods: Sixty pupils with UCS were divided into an exercise group and a combination group using the random number table method, with 30 cases in each group. The combination group received treatments of sinew-bone balancing manipulation plus exercise therapy, while the exercise group received exercise therapy alone. The two groups received interventions once every other day, for a total of 1 month. The sagittal static posture assessment total score, forward head angle (FHA) and forward shoulder angle (FSA) were compared before and after treatment; the sagittal static assessment total score, FHA and FSA were compared between the exercise group and the combination group. Results: Before treatment, there were no significant differences comparing the sagittal static posture assessment total score, FHA and FSA between the two groups (all P>0.05); after treatment, the sagittal static posture assessment total score, FHA and FSA decreased in the two groups, with intra-group statistical significance (all P<0.01), and were lower in the combination group than in the exercise group, with inter-group statistical significance (all P<0.01). Conclusion: Sinew-bone balancing manipulation plus exercise therapy can notably improve the FHA and FSA and reduce the sagittal static posture total score in pupils with UCS, so as to correct the bad postures and adjust UCS physique. It can produce more significant efficacy compared with exercise therapy alone.

Sleep fragmentation as an important clinical characteristic of sleep disorders in Parkinson’s disease: a preliminary study / 中华医学杂志(英文版)

Background@#Sleep disorders are one of the earliest non-motor symptoms of Parkinson’s disease (PD). Sleep disorders could, therefore, have value for recognition and diagnosis in PD. However, no unified classification and diagnostic criteria exist to evaluate sleep disorders by polysomnography (PSG). Utilizing PSG to monitor sleep processes of patients with PD and analyze sleep disorder characteristics and their relationship with demographic parameters could aid in bridging this gap. This preliminary study aimed to evaluate the clinical characteristic of sleep disorders in PD using PSG.@*Methods@#PSG was used to evaluate sleep disorders in 27 patients with PD and 20 healthy volunteers between August 2015 and July 2018 in Fujian Medical University Union Hospital. Total sleep time (TST), sleep efficiency (SE), total wake time, and other parameters were compared between the two groups. Finally, the correlation between sleep disorders and age, disease duration, Unified Parkinson’s Disease Rating Scale-III scores, Hoehn-Yahr stage, and levodopa dose were analyzed. The main statistical methods included Chi-square test, two independent samples t test, Fisher exact test, and Pearson correlation.@*Results@#Sleep fragmentation in the PD group was significantly increased (74.1%) while difficulty falling asleep and early awakening were not, as compared to healthy controls. No significant differences were found in time in bed, sleep latency (SL), non-rapid eye movement (NREM) stage 1 (N1), N1%, N2, N2%, N3%, and NREM% between PD and control groups; but TST (327.96 ± 105.26 min vs. 414.67 ± 78.31 min, P = 0.003), SE (63.26% ± 14.83% vs. 76.8% ± 11.57%, P = 0.001), R N3 (20.00 [39.00] min vs. 61.50 [48.87] min, P = 0.001), NREM (262.59 ± 91.20 min vs. 337.17 ± 63.47 min, P = 0.003), rapid-eyemovement (REM) (32.50 [33.00] min vs. 85.25 [32.12] min, P < 0.001), REM% (9.56 ± 6.01 vs. 15.50 ± 4.81, P = 0.001), REM sleep latency (157.89 ± 99.04 min vs. 103.47 ± 71.70 min, P = 0.034) were significantly reduced in PD group.@*Conclusion@#This preliminary study supported that sleep fragmentation was an important clinical characteristic of sleep disorders in PD. Whether sleep fragmentation is a potential quantifiable marker in PD needs to be further investigated in the future study.

Expression of COL5A2 in bladder cancer tissues and its correlation with clinicopathological features and prognosis / 实用肿瘤学杂志

Objective The aim of this study was to investigate the expression of COL5A2 in bladder cancer tissues,and its correlation with clinicopathological features and prognosis. Methods A total of 144 patients with bladder cancer were enrolled in this study. Real-time fluorescence reverse transcription and immunohistochemistry were used to detect the expression of COL5A2 at levels of mRNA and protein in bladder cancer tissues and normal bladder tissues. The relationship between COL5A2 expression and clinico-pathological features and prognosis was analyzed. Results The expression of COL5A2 mRNA in the bladder cancer group was higher than that in the paracancerous group(P<0. 05). The positive rate of COL5A2 in the bladder cancer group was higher than that in the normal bladder tissues(P<0. 05). The expression of COL5A2 protein was not correlated with age( P>0. 05),positively associated with the TMN stage,pathological grade,tumor maximum diameter(≥5 cm),depth of invasion,lymph node metastasis,lymphatic vas-cular infiltration,and recurrence;the difference was statistically significant(P<0. 05). The 3-year survival rate and survival time in the COL5A2 negative group were significantly higher than those in the COL5A2 positive group(P<0. 05). The higher TMN stage,the higher pathological stage,the maximum diameter of the tumor(≥5 cm),the deeper infiltration depth,lymph node metastasis,lymphat-ic vascular infiltration,recurrence,the higher positive expression rate of COL5A2 protein.

Bladder cancer patients with low expression of COL5A2 can obtain a good prognosis.

Analysis of factors related to anastomotic leakage after transanal total mesorectal excision / 国际外科学杂志

Objective To investigate the risk factors of anastomotic leakage after transanal total mesorectal excision.Methods Retrospective analysis of clinical data of 46 patients with rectal cancer who underwent TaTME surgery from May 2015 to May 2018 in Daping Hospital,Army Medical University.There were 22 males and 24 females,the median age was 61.2 (range from 40 to 79)years.To observe the correlation between perioperative factors and anastomotic leakage,including preoperative staging,operation time,bleeding volume,anastomotic approach,anastomotic height,intraoperative adverse events,and concurrent diseases.The software of SPSS 20.0 was adopted to analyze the above indicators.Results Among 46 patients with rectal cancer,38 were treated with TaTME combined with laparoscopic surgery,5 with robotic transanal combined with transabdominal surgery,and 3 with pure transanal total mesorectal excision.There were no deaths in the whole group.The incidence of postoperative anastomotic leakage was 13.0％,1 case of grade B and 1 cases of grade A anastomotic leakage,both accounting for 2.2％ and 4 cases of grade C anastomotic leakage,accounting for 8.7％.Anastomotic leak discovery time average (9.8 ± 4.8) d.No anastomotic leakage occurred in 17 cases of ileostomy.Among them,diabetes mellitus,protective ostomy,blood loss ≥ 100 ml,BMI,height of anastomosis and total operation time were significantly correlated with anastomotic leakage.Conclusions In addition to the influence of the learning curve during TaTME surgery,obesity,diabetes,anastomotic height,intraoperative blood loss ≥ 100 ml,and prolonged total operation time are risk factors for anastomotic leakage.Ileal protective ostomy is valuable for reducing anastomotic leakage.

Analysis on the policy response and its optimization strategies for family doctors'contractual service in Zhejiang / 中华医院管理杂志

The family doctor system is a collection of the rules and operating patterns formed during the interaction between the top design of "universal health coverage" and the "contractual experiment" at primary level. Its optimization and upgrading call for continuous attention to primary policy response. A questionnaire survey was made to medical workers at primary healthcare institutions in Zhejiang,to learn the comments and willingness of participation of family doctors for the contractual service policy. The survey found the poor policy response roots in such constraints as lack of effective connection between top level and primary level,poor incentive design,and delayed supporting policies. In view of upgrading supplier policy response,the authors recommended feasible strategies to optimize policy response, namely priori decision-making,process control,both hard and soft tactics,and parallel efforts for both internal and external sides.

Effects of different angiotensin II type 1 receptor blockers on regulation of ACE-Ang II-AT1 and ACE2-Ang(1-7)-Mas axes in pressure overload-induced cardiac remodeling in male mice / 中国病理生理杂志

AIM:To examine and compare the effects of several ARBs that are widely used in clinics , on the ACE-Ang II-AT1 receptor and the ACE2-Ang(1-7)-Mas axis during the development of cardiac remodeling after pressure overload .METHODS: All of the mice used in the study underwent transverse aortic constriction (TAC) or sham operation for 2 or 4 weeks.A solution of either ARBs or sa-line was administered through a stomach tube 3 days before the operation .Meanwhile , to eliminate the influence of Ang II , a recombi-nant adenovirus expressing small interfering RNAs targeting angiotensinogen ( Ad-ATG siRNA) was injected via the tail vein .The sur-gery was then performed and the drug was administered as mentioned above .Cardiac function and remodeling were evaluated by echo-cardiography , hemodynamic measurements and cardiac histology .Western blotting was used to determine the protein expression levels . Meanwhile , we performed similar experiments using ARBs with or without ATG siRNA in cardiomyocytes induced by mechanical stretch.RESULTS:Although all of the six ARBs , none of which repressed the elevation of left ventricular pressure after TAC , attenu-ated the development of cardiac hypertrophy and heart failure in the wild-type mice, the degree of attenuation by Olmesartan , Candesar-tan and Losartan tended to be larger than that of the other three drugs tested .Additionally , the degree of downregulation of the ACE-Ang II-AT1 axis and upregulation of the ACE2-Ang(1-7)-Mas axis was higher in response to Olmesartan, Candesartan and Losartan administration in vivo and in vitro.Additionally, Olmesartan had a larger influence when administered long term .However, the expres-sion of ACE was not influenced by the administration of ARBs in vivo and in vitro.Moreover, in angiotensinogen-knockdown mice, TAC-induced cardiac hypertrophy and heart failure were inhibited by Olmesartan , Candesartan and Losartan but not by Telmisartan , Valsartan and Irbesartan administration .Furthermore , only Olmesartan and Candesartan could downregulate the ACE-Ang II-AT1 axis and upregulate the ACE2-Ang(1-7)-Mas axis in vitro.CONCLUSION: Olmesartan, Candesartan and Losartan could effectively in-hibit pressure overload-induced cardiac remodeling even when with knockdown of Ang II , possibly through upregulation of the expres-sion of the ACE2-Ang(1-7)-Mas axis and downregulation of the expression of the ACE-Ang II-AT1 axis.In contrast, Telmisartan, Valsartan and Irbesartan only played a role in the presence of Ang II , and Losartan had no effect in the presence of Ang II in vitro.

Establishment of a Novel Mouse Model of Coronary Microembolization / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Coronary microembolization (CME) has been frequently seen in acute coronary syndromes and percutaneous coronary intervention. Small animal models are required for further studies of CME related to severe prognosis. This study aimed to explore a new mouse model of CME.</p><p><b>METHODS</b>The mouse model of CME was established by injecting polystyrene microspheres into the left ventricular chamber during 15-s occlusion of the ascending aorta. Based on the average diameter and dosage used, 30 C57BL/6 male mice were randomly divided into five groups (n = 6 in each): 9 μm/500,000, 9 μm/800,000, 17 μm/200,000, 17 μm/500,000, and sham groups. The postoperative survival and performance of the mice were recorded. The mice were sacrificed 3 or 10 days after the surgery. The heart tissues were harvested for hematoxylin and eosin staining and Masson trichrome staining to compare the extent of inflammatory cellular infiltration and fibrin deposition among groups and for scanning transmission electron microscopic examinations to see the ultrastructural changes after CME.</p><p><b>RESULTS</b>Survival analysis demonstrated that the cumulative survival rate of the 17 μm/500,000 group was significantly lower than that of the sham group (0/6 vs. 6/6, P = 0.001). The cumulative survival rate of the 17 μm/200,000 group was lower than those of the sham and 9 μm groups with no statistical difference (cumulative survival rate of the 17 μm/200,000, 9 μm/800,000, 9 μm/500,000, and sham groups was 4/6, 5/6, 6/6, and 6/6, respectively). The pathological alterations were similar between the 9 μm/500,000 and 9 μm/800,000 groups. The extent of inflammatory cellular infiltration and fibrin deposition was more severe in the 17 μm/200,000 group than in the 9 μm/500,000 and 9 μm/800,000 groups 3 and 10 days after the surgery. Scanning transmission electron microscopic examinations revealed platelet aggregation and adhesion, microthrombi formation, and changes in cardiomyocytes.</p><p><b>CONCLUSION</b>The injection of 500,000 polystyrene microspheres at an average diameter of 9 μm is proved to be appropriate for the mouse model of CME based on the general conditions, postoperative survival rates, and pathological changes.</p>
