Objective To understand the awareness and willingness of primary medical staff in Songjiang District, Shanghai towards human papillomavirus (HPV) and its vaccines, and to provide references for improving the vaccination willingness of HPV vaccine and primary prevention of cervical cancer. Methods From July to August 2023, a questionnaire survey was conducted among the in-service medical staff in 17 community health service centers in Songjiang District, Shanghai, using the random sampling method. Descriptive analysis, χ² test and logistic regression were used for statistical analysis. Results A total of 951 valid questionnaires were collected during the survey. The awareness rate of HPV among medical staff was 92.74%, and the awareness rate of HPV vaccine was 93.38%. The maximum score for HPV knowledge was 6 points, with an average score of (3.99±1.34) points. The maximum score for HPV vaccine knowledge was 10 points, with an average score of (5.63±1.61) points. 881 (92.64%) medical staff were willing to receive or recommend HPV vaccination. Multivariate analysis showed that concerns about being infected with HPV (OR=2.648, 95% CI: 1.459-4.806), qualified score on HPV vaccine knowledge (OR=1.717, 95% CI: 1.012-2.912), high price burden of HPV vaccine (OR=0.343, 95% CI: 0.157-0.746), and concerns about side effects of vaccination (OR=0.443, 95% CI: 0.243-0.805) were the influencing factors for medical staff's willingness to vaccinate. Conclusion There is insufficient knowledge of HPV and its vaccines among primary medical personnel in Songjiang District, Shanghai. It is necessary to strengthen the continuing education of medical personnel through multiple channels, supplement the HPV-related knowledge system, and eliminate their concerns about vaccines.

Objective To investigate the relationship between the expression of matrix metalloproteinase(MMP)-2,MMP-9,MMP-13 and disease activity in pemphigus patients.Methods A total of 60 pemphigus patients treated in the dermatology department of the hospital from January 2021 to January 2023 were select-ed as the study group,and another 60 healthy volunteers who underwent physical examination in the same pe-riod were recruited as the control group.The levels of MMP-2,MMP-9 and MMP-13 in serum and the expres-sion of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells were compared between the two groups,and the relationship between the expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of patients with pemphigus was analyzed.Pemphigus patients were divided into acute phase group(n=22),chronic phase group(n=23)and stable phase group(n=15)according to their disease activi-ty.The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of the three groups were compared,as well as the correlation between the three indexes and disease activity.Receiver operating characteristic(ROC)curve was plotted for analysis.Results The levels of MMP-2,MMP-9 and MMP-13 in serum and the expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells in the study group were higher than those in the control group,with statistical significance(P＜0.05).The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells in severe patients were higher than those in moderate and mild patients,and the difference was statistically significant(P＜0.05).The expression of MMP-2,MMP-9 and MMP-13 and disease activity scores of mononuclear cells in acute attack group were higher than those in chronic attack group,and the differences were statistically significant(P＜0.05).The ex-pression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells were positively correlated with disease activity(rMMP-2=0.545,rMMP-9=0.592,rMMP-13=0.580,P＜0.05).ROC curve analysis showed that compared with the single diagnostic efficacy of MMP-2,MMP-9 and MMP-13 expression in peripheral blood mononuclear cells,the three combined diagnostic efficacy was better.Conclusion The expression of MMP-2,MMP-9 and MMP-13 in peripheral blood mononuclear cells of pemphigus patients is related to the disease activity,and these three indicators can be used as reference indicators for the diagnosis of pemphigus disease activity.

Objective:To investigate the effect and mechanism of esophageal squamous cell carcinoma exosomal miR-181b-5p to the polarization of M2 macrophages.Methods:Extracted and identified exosomes from esophageal squamous cell carcinoma,and detected the expression of miR-181b-5p in esophageal squamous cell carcinoma cells and their exosomes by qRT-PCR.M0 type macro-phages were divided into PBS group,HEEC exo group,Eca-109 exo group,miR-NC exo group,miR-181b-5p exo group,miR-NC group,miR-181b-5p mimic group,si-NC group,si-PTEN group,miR-181b-5p exo+PTEN group.qRT-PCR was used to detect the expressions of CD163,CD206,iNOS and TNF-α in each group.The targeting relationship between miR-181b-5p and PTEN were veri-fied by double luciferase reporter gene experiment.Results:miR-181b-5p was significantly overexpressed in esophageal squamous cell carcinoma cells TE-13,TE-12,TE-10,Eca-109,KYSE30 and their exosomes(P<0.001).Compared with miR-NC group,the expression of CD163 and CD206 in cells were significantly upregulated in the miR-181b-5p mimic group,as well as the expressions of iNOS and TNF-α were significantly downregulated(P<0.001).The results of double luciferase reporter genes showed that PTEN was the target gene of miR-181b-5p.Compared with si-NC group,the expressions of CD163 and CD206 in cells were significantly upregu-lated in the si-PTEN group,as well as the expressions of iNOS and TNF-α were significantly downregulated(P<0.001).Compared with PBS group,the expressions of CD163 and CD206 in cells were significantly upregulated in the Eca-109 exo group,as well as the expressions of iNOS and TNF-α were significantly downregulated(P<0.001).Compared with miR-NC exo group,the expressions of CD163 and CD206 in cells were significantly upregulated in the miR-181b-5p exo group,as well as the expressions of iNOS and TNF-α were significantly downregulated(P<0.001).Compared with miR-181b-5p exo group,the expressions of CD163 and CD206 in cells were significantly downregulated in the miR-181b-5p exo+PTEN group,as well as the expressions of iNOS and TNF-α were significantly upregulated(P<0.001).Conclusion:Exosomal miR-181b-5p inhibits PTEN expressions to promote M2 macrophage polarization.

Objective To study the antifungal activity of a new series of triazole compounds with n-propyl side chain and disubstituted benzyl structure. Methods Eleven target compounds were designed and synthesized. The structures were confirmed by ¹H NMR, and some compounds were confirmed by ¹³C NMR or HRMS. Three fungal strains were selected as experimental strains, and the antifungal activity was tested in vitro according to the standardized antifungal sensitivity test method recommended by National Committee for Clinical Laboratory Standards (NCCLS). Results Compound B11 showed better activity against candida albicans SC5314 than fluconazole and was comparable to posaconazole; Compounds B10, B11 and B4 showed better activity against cryptococcus neoformanis H99 than fluconazole, while compounds B2, B3, B5, B6 and B7 showed similar activity to fluconazole against cryptococcus neoformanis H99; while all compounds showed poor activity against aspergillus fumigatus. Conclusion Some of the target compounds with n-propyl side chain and disubstituted benzyl group structure had certain antifungal activity and could be identified as potential lead antifungal drugs.

Objective:To investigate the relationship between histone deacetylase (HDAC) gene polymorphism and type 2 diabetes mellitus (T2DM) in Bai and Han populations in Dali of Yunnan province.Methods:A total of 148 patients with T2DM of Bai and Han nationalities who received treatment in Dali Bai Autonomous Prefecture People's Hospital from May 2019 to March 2021 were included in the T2DM group. An additional 100 healthy controls of Bai and Han nationalities who concurrently received physical examination in the same hospital from May 2019 to December 2020 were included in the normal control group. The susceptibility genes of T2DM were detected using the Taqman MGB probe method. The susceptibility gene loci were amplified using polymerase chain reaction. The whole sequence of susceptibility gene was sequenced.Results:There were no significant differences in the distribution frequencies of rs2530223 genotype, rs11741808 genotype, rs2547547 genotype, and rs1741981 genotype between Bai and Han populations (all P > 0.05). There was a significant difference in blood lipid level between four loci ( t = -1.06, -0.19, 0.39, -2.12, -2.04, 0.16, 1.47, < 0.01, -0.16, -3.17, -2.93, 0.69, -2.58, -2.33, all P < 0.05). There was a significant difference in homeostasis model assessment of insulin resistance between different states (all P < 0.05). The frequency distributions of each genotype and each allele did not differ significantly between healthy control people of Bai nationality and T2DM patients of Bai nationality and between healthy control people of Han nationality and T2DM patients of Han nationality (all P > 0.05). Logistic regression analysis showed that the polymorphism was not an independent risk factor for T2DM. Conclusion:The relationships between HDAC gene polymorphism and T2DM, obesity and dyslipidemia differ between Bai and Han populations.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective: To investigate the risk factors of road traffic injuries caused by electric bicycles, so as to provide insights into the prevention and control of road traffic injuries. Methods: A case-control study was performed (cases to controls ratio of 1∶2). The riders of electric bicycles with road-traffic injuries in Songjiang District, Shanghai Municipality during the period between June 2020 and May 2021 were included in the case group, and age-, gender- and occupation-matched riders of electric bicycles without road-traffic injuries in the same study area during the same study period served as controls. Participants' demographic data, living habits, health status, awareness of safe riding and riding behaviors were collected using questionnaire surveys, and the risk factors of road-traffic injuries caused by electric bicycles were identified using a multivariable conditional logistic regression model. Results: There were 167 participants in the case group, including 122 men (73.05%) and with an age of 38 (21) years, and 334 participants in the control group, including 244 men (73.05%) and with an age of 32 (18) years. Multivariable conditional logistic regression analysis identified sleep duration of less than 8 h (OR=1.760, 95%CI: 1.111-2.786), occasional/frequent anxiety (OR=5.140, 95%CI: 1.067-24.750), unawareness of riding speed limit of 25 km/h (OR=2.352, 95%CI: 1.460-3.788), having been warned or punished for violating traffic rules (OR=2.246, 95%CI: 1.243-4.060), running a red light (OR=1.725, 95%CI: 1.043-2.852), riding speed of ≥ 30 km/h (sometimes, OR=2.409, 95%CI: 1.475-3.933; often, OR=4.711, 95%CI: 2.153-10.309) as risk factors of electric bicycle road-traffic injuries. Conclusions Electric bicycle road-traffic injuries is associated with sleep duration, anxiety, awareness of traffic rules, and unsafe riding behaviors. Traffic safety education and law enforcement is required to be reinforced among riders of electric bicycles.

Objective:To understand the 10-year risk of ischemic cardiovascular disease (ICVD) in hypertensive patients in communities in Shenzhen, and to provide baseline data for the comprehensive implementation of community-based hypertension health management measures based on ICVD risk assessment.Methods:From July 2017 to June 2018, 200 community health service centers in 10 districts of Shenzhen were selected by multi-stage random sampling to investigate hypertensive patients in communities aged≥35. After the patients who met the inclusion criteria signed the informed consent form, the demographic characteristics, physical examination, and laboratory tests were conducted. The absolute risk of ICVD in 10 years was evaluated by using the ICVD risk assessment module from the Shenzhen community health service information system. According to the China 10-year risk for ICVD score tables, recommended by the Chinese cardiovascular disease prevention guidelines, the risk grade of ICVD was estimated and analyzed. In addition, the relative risk was used to eliminate the influence of gender and age, and the single sample t-test was used for comparisons with the larger population. Results:30 015 hypertensive patients from communities were investigated, including 16 165 (53.86%) males and 13 850 (46.14%) females, aged 35-102 years, with a median age of 59.0. 6 405 (21.34%), 5 771 (19.23%) and 17 839 (59.43%) were at high, medium and low risk of ICVD, respectively. The absolute risk was 3.77%, 95% CI (3.72%-3.82%). The risk grades of ICVD in 10 years was different as per gender, age, marital status, population type， smoking, family history of hypertension, history of diabetes mellitus, systolic blood pressure, body mass index, and total cholesterol level, P values were all<0.001. The risk grades of ICVD in males, married patients, floating populations, having a total cholesterol <5.20 mmol/L, non-smokers, non-diabetics, and having a family history of hypertension were lower than that of other characteristics, and increased with age, systolic blood pressure, and body mass index. Further analysis of 15 652 patients aged 35-59 years old showed that the 10-year risk of ICVD in patients with hypertension in communities was slightly higher than that of the larger population, and the relative risk was 1.27, 95% CI (1.25-1.28), t=37.648, P<0.001. In males, relative risk was 0.94, 95% CI (0.93-0.95), t= 9.906, P<0.001, and there were no significant trend changes among age groups. In females, relative risk was 2.05, 95% CI (2.01-2.09), t=72.207, P<0.001, and increased with age. Conclusion:The 10-year risk of ICVD in hypertensive patients is often at a high level in Shenzhen, so it is necessary to carry out the risk assessment of ICVD in the community. The effect of community hypertension health management on reducing the risk of ICVD may vary between genders. The risk of ICVD in male patients is lower than that of males in the larger population, but in female patients it is still much higher.

Objective To explore the effect of omni-directional health education on self-management level and blood glucose control in patients with type 2 diabetes mellitus. Methods A total of 100 diabetic patients admitted to the department of neurology of Taizhou Central Hospital from January to December 2016 were randomly divided into an observation group and a control group, 50 cases in each group. All patients were given conventional medication according to their systemic conditions, the control group used conventional nursing care, while the observation group was supplemented with omni-directional health education (including diet control therapy, exercise therapy, blood glucose control, hypoglycemic drug use and observation, foot care, blood glucose self monitoring) on the basis of routine nursing;the course of treatment was 2 weeks in the two groups. The differences in self-management level and the effect of blood glucose control were compared between the two groups. Results On the return visits, the self-management scores were significantly higher in both groups than those before education (the control group was 35.2±9.2 vs. 30.1±5.2, the observation group was 78.6±11.5 vs. 29.8±5.4, all P < 0.05), fasting blood glucose [FBG (mmol/L): the control group was 8.8±2.5 vs. 14.8±2.9, the observation group was 6.1±1.6 vs. 15.1±2.7, both P < 0.05) and 2 hours postprandial blood glucose [2 h PBG (mmol/L): the control group was 12.5±3.4 vs. 22.5±3.8, the observation group was 9.1±2.2 vs. 21.9±3.6) were obviously lower than those before education (all P < 0.05), the degrees of improvement of the observation group were more significant than those of the control group [self management score: 78.6±11.5 vs. 35.2±9.2, FBG (mmol/L): 6.1±1.6 vs. 8.8±2.5, 2 hours PBG (mmol/L): 9.1±2.2 vs. 12.5±3.4, all P < 0.05]. Conclusion Omni-directional health education can improve the self-management level of diabetic patients, and the patient's blood glucose control is relatively better.

Four cases of Pentalogy of Cantrell were diagnosed by prenatal ultrasonography and confirmed by autopsy after labor induction.There were 1 case of complete Pentalogy of Cantrell and 3 cases of incomplete Pentalogy.In 3 cases of incomplete Pentalogy of Cantrell,1 case presented with high umbilical cord prolapse,extraspectoral heart,partial defect of the lower part of the sternum,partial defect of the pericardium,single umbilical artery and cervical lymphatic cyst;1 case presented with high umbilical cord prolapse,extraspectoral heart,thoracic fissure and ventricular septal defect;and 1 case presented with umbilical cord,extraspectoral heart,partial inferior sternal segment defect,ventricular septal defect and bilateral clubfoot varus.In l case of complete Pentalogy of Cantrell,there were high umbilical cord bulge,extraspectoral heart,chest fissure and inferior segment defect,anterior diaphragm and pericardium defect,total forebrain deformity,right 12th ribs loss and ventricular septal defect.Ectopic heart and omphalocele are typical echographic features of Pentalogy of Cantrel and prenatal ultrasonography is of important value in early diagnosis of this congenital malformation.
