ABSTRACT
Objective:Comparison of four methods in intraoperative abduction angles (AA) measurements of human cast immobilization in developmental dysplasia of the hip (DDH) by visual inspection and electronic software according to different body surface markers.Methods:Data were retrospectively collected from January 2019 to November 2021 in a total of 27 patients (54 hips) who underwent closed or simple open reduction. There were 6 males and 21 females with an average age of 13.2 months. Five doctors used visual inspection and mobile phone software to measure the AA of the hip joint immediately during the operation, and compared with the postoperative MRI measurement results (AA-MRI). The four methods of intraoperative measurement were: Junior visualization (AA-JV), the intersection angle between the line connecting the center of the popliteal fossa and the contact center of the plaster frame and the line connecting the two ischial tuberosities; the same methods as method one by Senior visualization (AA-SV); the intersection angle between the line connecting the center of the popliteal fossa and the center of the anus and the line connecting the ischial tubercle (anus-popliteal, AA-AP); the intersection of the vertical line between the center of the popliteal fossa and the groin and the horizontal line of the center of the anus and the vertical line connecting the two ischial tuberosities intersect (anus-groin crease-popliteal, AA-AGCP). The t-test, correlation coefficient, linear regression and Bland-Altman test were used to evaluate the measurements. Results:Comparing the four intraoperative and postoperative AA-MRI measurement methods, AA-JV (42.69°±4.13°) < AA-SV (44.80°±4.08°) < AA-AGCP (46.25°±5.15°) < AA-MRI (47.68°±4.21°) < AA-AP (51.77°±5.30°), and the difference between AA-JV and AA-SV, AA-AP and AA-AGCP was statistically significant ( t=2.53, P=0.013; t=5.47, P=0.001), there was no significant difference between AA-AGCP and AA-MRI ( t=1.57, P=0.118). The inter-group agreement of the five methods ICC test ranged from 0.807 to 0.892, and the intra-group average agreement of AA-MRI was 0.948. All ICC results were greater than 0.75 with good agreement. Linear regression results showed that the four intraoperative measurement methods had a good or moderate linear relationship with AA-MRI, AA-AGCP ( R 2=0.499)>AA-AP ( R 2=0.318)>AA-SV ( R 2=0.253)>AA-JV ( R 2=0.217), AA-AGCP was the best measurement method. The results of Bland-Altman scatterplot of AA-AGCP and AA-MRI were in good agreement, the mean and standard deviation of bias were -0.796±3.247, and the limit of agreement was 95% LoA (-7.16, -5.57). Conclusion:The AA method of visualization before Spica casting was smaller than truth. The method AA-AGCP objectively by landmarks was the advocated means measuring abduction angle during operation with highly consistency, agreement and easily performed.
ABSTRACT
Placenta, the direct and vital connection between mother and fetus, can be considered as an inflammatory organ that plays an essential role in maternal-fetal immune tolerance in maintaining pregnancy and mediating inflammation in some gestational complications. When gestational diabetes mellitus (GDM) occurs, the mother and placenta are in a state of mild inflammation. We hypothesize that the placental immune cells may participate in the pathogenesis of GDM. This review discusses the relation between placental immune cells and GDM from three aspects: the regulatory function of the placental immune cells, the association between abnormal placental immune cells and GDM, and the function of placental immune cells during clinical management of GDM.

Conclusion The method is simple,rapid, accurate and reliable for the determination of isochlorogenic acid A and isochlorogenic acid C in Vernonia anthelmintica and also for the quality control of the raw material.
ABSTRACT
Objective To compare the value of computed tomography(CT)and magnetic resonance im-aging(MRI)in assessing the curative effect of primary liver cancer after transcatheter arterial chemoembolization (TACE). Methods 45 patients with primary hepatocellular carcinoma treated with TACE for 3 ～ 5 times were included in the research. CT ,MRI and digital subtraction angiography (DSA) were performed after treatment. DSA was used as a standard to analyze the lesions ,residual or lesion recurrence and the detection of tumor cap-sule in CT and MRI DSA. Results The scanning accuracy and sensitivity of residual lesions or lesion recurrence after TACE in CT was much lower than MRI ,and there is a significant difference between the two groups (P <0.05). In terms of tumor capsule detection accuracy after TACE ,CT was much lower than MRI(P < 0.05). In detection rate of residual or lesion recurrence in different types of lipiodol deposition after TACE ,CT was much lower than MRI (P < 0.05). Conclusions Compared with the CT test ,MRI detection has a higher accuracy and sensitivity of residual lesions or recurrence after TACE. MRI can not only effectively show the tumor cap-sule ,but also detect residual lesion or lesion recurrence of different types of lipiodol deposition. MRI is superior to CT in the evaluating the curative effect of primary liver cancer after TACE.

ABSTRACT
Objective To study the effect of heterozygous deficiency of SGT gene on the hematological and biochemical parameters of mice in young and elderly ages.Methods Blood samples were analyzed for complete hematological and biochemical parameters from heterozygous SGT-deficient and wild-type mice of 10-weeks and 6-months old mice, respectively.Results Age-related changes in most indexes were found statistically significantly different between young and elderly mice with the same genotype.Compared with the wild type at the same age, the platelet large cell ratio (P-LCR) was lower in young heterozygous SGT-deficient mice.However, platelet count, plateletcrit (PCT) and neutrophil count were more significantly lower in elderly heterozygous SGT-deficient mice (P<0.05).There was no significant difference for biochemical parameters ALT, AST, LDH, urea nitrogen, creatinine and blood glucose.Total and unconjugated bilirubin as well as ALP were significantly higher in elderly heterozygous SGT-deficient mice but not for conjugated bilirubin (P<0.05).In addition, significant differences existed for the lipids between two elderly groups (P<0.05).Conclusions Heterozygous deficiency of SGT gene induced changes of some hematological and biochemical parameters in elderly mice.It provides helpful information for further investigation on SGT involvement in some biological and pathological processes.
ABSTRACT
Objective To investigate the role of macrophage?derived Act1 (nuclear factor kappa B activator 1) in the inflammatory bowel disease. Methods Genetically engineered mice carrying targeted suppression of Act1 in the mac?rophages (Anti?Act1) were used for the dextran sodium sulfate (DSS)?induced ulcerative colitis. The severity of colitis was assessed by weight loss, stool consistency, fecal blood index, colorectal length and H&E histology. The infiltration of CD45 + leukocytes and CD68 + macrophages in the inflammatory intestine was observed by immunohistochemical staining and expression levels of mRNA for inflammatory cytokines in colon tissues were analyzed by RT?qPCR. Results As com?pared with C57 mice, the anti?Act1 mice exhibited less severe acute colitis following DSS treatment, with reduced CD45 +leukocyte and CD68 + macrophage infiltrates in the colon tissue. Inflamed colons of the anti?Act1 mice expressed lower mR?NA levels of TNF?α, IL?1βand IL?6. Conclusions Targeted suppression of Act1 in the macrophages ameliorates dextran sodium sulfate?induced intestinal inflammation.

ABSTRACT
Objective: To explore the value of dual energy CT lung perfusion imaging (DEPI) for diagnosing pulmonary embolism (PE) in comparison with CT pulmonary angiography (CTPA). Methods: There were 49 patients with suspected PE received DEPI scanning and 19 with CTPA conifrmed diagnosis were enrolled in this study. CTPA image was obtained by 80 kv data, and DEPI image was obtained by PBV software. The location, type of PE in CTPA image, and the location, shape of perfusion defect in DEPI were observed and compared by segment basis. The correlation and agreement of CTPA and DEPI for diagnosing PE were calculated and the un-agreement was analyzed. Results: A total of 380 segments were included for analysis. CTPA detected 162 segments of PE and DEPI detected 155 segments of perfusion defect or reduction, partial PE were mainly presented by perfusion defects as speckles, patches or without perfusion defect, and complete PE were mainly showed segmental or sub-segmental perfusion defects. CTPA and DEPI were correlated for PE diagnosis (χ2=305.5,P=0.000), the diagnostic agreement was 83.42% and KAPPA value was 0.659. Conclusion: The perfusion defect in DEPI is related to the degree and type of PE presented in CTPA, their combination is helpful for diagnosing PE.

ABSTRACT
Objective To discuss the safety and clinical effect of fine needle single-step centesis in percutaneous endoscopic nephrolithotomy for renal staghorn calculi. Methods Percutaneous endoscopic nephrolithotomy with fine needle single-step centesis was employed in 75 patients (single-step group) with renal staghorn calculi, and percutaneous endoscopic nephrolithotomy with two-step centesis was adopted in other 75 patients with renal staghorn calculi (two-step group). The clinical effect and the incidence of complications were compared between the two groups. Results The placement of drainage catheter was successfully accomplished in all 150 patients. In single-step group the operation time was 18-45 minutes with a mean of 36 minutes; the mean blood loss during the procedure was about 5 ml. After the treatment, massive bleeding occurred in 3 cases that needed blood transfusion, and residual stone was observed in 6 cases. In two-step group the operation time was 16-42 minutes with a mean of 34 minutes; the mean blood loss during the procedure was about 7 ml. After the treatment, massive bleeding occurred in 7 cases that needed blood transfusion; one of them had renal pseudoaneurysm and the bleeding was stopped after renal artery embolization treatment; and residual stone was observed in 7 cases. No procedure-related perirenal organ injury was seen in single-step group, while in two-step group pneumothorax (n=1) and injury of splenic flexure of colon (n=1)were found. Conclusion In performing percutaneous endoscopic nephrolithotomy, fine needle single-step centesis is more safe and effective than conventional two-step centesis.

ABSTRACT
Objective To perform a systematic review and meta-analysis of the predictive abilities of CHADS2 and CHA2DS2-VASc in stroke and thromboembolism risk stratification of atrial fibrillation (AF) patients. Methods We searched PubMed and EMBASE for Eng-lish-language literature on comparisons of the diagnostic performance between CHADS2 and CHA2DS2-VASc in predicting stroke, or sys-temic embolism, in AF. We then assessed the quality of the included studies and pooled the C-statistics and 95%confidence intervals (95%CI). Results Eight studies were included. It was unsuitable to perform a direct meta-analysis because of high heterogeneity. When analyzed as a continuous variable, the C-statistic ranged from 0.60 to 0.80 (median 0.683) for CHADS2 and 0.64-0.79 (median 0.673) for CHA2DS2-VASc. When analyzed as a continuous variable in anticoagulation patients, the subgroup analysis showed that the pooled C-statistic (95%CI) was 0.660 (0.655-0.665) for CHADS2 and 0.667 (0.651-0.683) for CHA2DS2-VASc (no significant difference). For non-anticoagulation patients, the pooled C-statistic (95%CI) was 0.685 (0.666-0.705) for CHADS2 and 0.675 (0.656-0.694) for CHA2DS2-VASc (no significant differ-ence). The average ratio of endpoint events in the low-risk group of CHA2DS2-VASc was less than CHADS2 (0.41%vs. 0.94%, P＜0.05). The average proportion of the moderate-risk group of CHA2DS2-VASc was lower than CHADS2 (11.12%vs. 30.75%, P＜0.05). Conclu-sions The C-statistic suggests a similar clinical utility of the CHADS2 and CHA2DS2-VASc scores in predicting stroke and thromboem-bolism, but CHA2DS2-VASc has the important advantage of identifying extremely low-risk patients with atrial fibrillation, as well as classi-fying a lower proportion of patients as moderate risk.

(2) The Logistic regression analysis showed four risk factors for mortality of AP,including obesity,AGI,GBA and suprahepatic space effusion.The sensitivity,specificity and accuracy of Logistic regression model for predicting mortality were 33.3％, 98.6％, 96.0％, respectively.Conclusions Abdominal CT scan effectively indicates the signs of tissue and organ involvement in AP.These CT findings relate with the prognosis of AP.
ABSTRACT
ObjectiveTo investigate the morphologic features of coronary sinus (CS)-left atrium muscle connections,and evaluate the function and anatomical features of coronary sinus on dual-source CT coronary angiography (DSCTCA).MethodsImages of DSCTCA of 144 patients [ control group consisted of 96 patients,and atrial fibrillation (AF) group consisted of 48 patients] were reviewed.The existence of coronary sinus-right atrium muscle connections was indirectly evaluated by measuring the cross-sectional area changes of the CS during atrial systole and atrial diastolic.The number,location,length of the CS-left atrium muscle connections andthe relationship between CS-left atrium muscle connections and CS morphological characteristics were studied.The t test for continuous variables and Chi-square test for categorical variables were used in statistical analysis.Results( 1 )The anatomic course of the CS in relation to the mitral ring was straight,mild curvature and high riding of 62,16 and 18 cases in control group and 10,8 and 30 cases in AF group,respectively.There was not statistical significance between the 2 group (x2 =0.093,P=0.954). (2)The CS length was (34.1 ±9.1),(33.8 ±8.9)mm in Control group and AF group,respectively.There was no statistical significance between the 2 group ( t =- 0.486,P =0.628 ).(3) Coronary sinus-left atrium muscle connections were seen in 131 of the 144 patients (91.0％).A single connection was seen in 103 of the 144 patients,with a mean length of (22.6 ± 12.7)mm within (6.3 ± 5.8 ) mm of the coronary sinus ostium.28 patients had two connections; distal connections measured ( 13.2 ± 6.2)mm in length within (16.7 ± 6.8 ) mm of the coronary sinus ostium,and proximal connections measured ( 11.1 ± 3.6 ) mm in length within (2.1 ± 1.9) mm of the coronary sinus ostium.And there was no statistical difference the number and length of CS-left atrium connections in between Control group and AF group (P ＞ 0.05 ).(4)The CS narrowed 22.4％ (44.5/198.8 )in cross-sectional area from atrial diastolic to atrial systole in control group( t =- 21.076,P ＜ 0.01 ),while the CS had no obvious contraction in AF group(t =0.374,P ＞ 0.05).The cross-sectional area of the coronary sinus during diastole was obviously larger in the AF group than in the control group[( 230.4 ±77.0) mm2 vs (198.8 ±65.4) mm2,respectively,t =- 2.579,P =0.01 ].In control group ( n =9 ),the coronary sinus-left atrium connection was not seen,however,all showed a CS constriction during atrial systole,indicating that coronary sinus-left atrium muscle continuity is not likely the primary cause for coronary sinus contractions. Conclusions DSCTCA can clearly show the anatomical characteristics of CS,it can help to understand the length,number and location of the CS-left atrium muscle connection.

ABSTRACT
Objective To investigate the morphologic features of Bachmann bundle (BB) and its vascular supply on dual-source CT coronary angiography(DSCTCA) in healthy volunteers and patients with coronary artery lesion (CAL). Methods Clinical histories, electrocardiograms (ECGs), and images of DSCTCA of 106 patients ( CAL group) and 100 healthy volunteers ( Control group) were reviewed. All 106 patients underwent conventional coronary angiography ( CCA ). The Gensini scoring system was used to assess the results of CCA. The patients were divided into three groups according to their Gensini scores. The length, width and superoinferior diameter, CT value, and vascular supply of BB were studied. Rank sum test for continuous variables and Chi-square test for categorical variables were used in statistical analysis.Results ( 1 ) BB visualization rate of control group was higher than CAL group [86.0% (86/100) vs 51.9%(55/106), x2 = 27.726, P ＜ 0.01]. The higher the Gensini score of CAL subgroup, the lower the visualization rate of its BB [80.0% ( 28/35 ), 55.6% ( 20/36 ), 20.0% ( 7/35 ), x2 = 25.530, P ＜ 0.01].(2)The median of measurements of length,width and superoinferior diameter of control and CAL group were 13.0 vs 13.8,5.0 vs 5.2 and 5.9 vs 6.2 mm, respectively ( P ＞ 0.05 ). (3) The CT value of the BB region in control group( median :42.6 HU ) was higher than that of CAL group( median: 13.0 HU) ( Z = - 7.061, P ＜0.01). The CT values of BB regions in patients with nonvisualized BB (median: -16.0 HU) were lower. The CT values of the BB regions in CAL group were negatively-correlated with Gensini scores( median:19.0) (r = -0.553, P ＜0.01 ). (4)The blood supply of BB and BB region was provided by right sinuatrial node artery ( SNA, 58.7%, 121/206 ), left SNA ( 35.9%, 74/206 ) or both SNAs ( 5.3%, 11/206 ).Conclusions DSCTCA could can show the anatomical characteristics of BB and its arterial supply. The serious the degree of CAL , the lower the BB display rate, and the higher the abnormal ECG incidence,which indicate that the occurrence of BB lesions is probably related to ischemia.
ABSTRACT
Objective To investigate the clinical features and human papillomavims (HPV) types in 12 cases of HPV infection characterized by pseudocondyloma of vulvae. Methods Twelve women, who had a history of sexual behavior with non-spouses and presented with pseudocondyloma of vulvae, were included in this study. Tissue specimens were scraped or resected from the lesions of pseudocondyloma of vulvae. PCR-based reverse hybridization assay was performed to determine the genotypes of HPV. Results All the 12 specimens were HPV positive. The reverse hybridization assay generated 13 subgenotypes of HPV, including 3 low-risk genotypes (11, 42 and 43) and 10 high-risk genotypes (16, 18, 31, 33, 35, 39, 51, 52, 58 and 59). All the patients were found to be infected by at least one high-risk genotype. Of the 12 patients, 4 were infected by single type of HPV, 6 by 2 types of HPV, and 2 by 3 or 4 genotypes of HPV. Conclusion The patients characterized by pseudocondyloma of vulvae may suffer from high-risk HPV infection.
