Objective To evalute the incidence and epidemiologic characteristics of Kawasaki disease (KD) in Wenzhou,China.Methods We used a questionnaire survey and reviewed the medical records and reports of all patients with KD diagnosed during the 10 year periods from January,2001 to December,2010.Results We studied 827 inpatients diagnosed with KD during the 10-years period from 2001 to 2010.There were 613 cases (74.12％) with complete KD.The ratio of male to female ratio was 2.28∶1.Age at onset ranged from 37 days to 13 years old,and the peak age group was 1 year old.The disease occurred in all of the seasons,but the peak was from April to June.The incidence of cardiovascular damage in acute KD was 34.6％,and the most common sequela was coronary artery dilatation.There were16 patients with coronary aneurysm.Fifty-three patients did not respond to immunoglobulin (6.4％),and 12 patients (1.5％) developed recurrent KD.After treatment,114 cases (13.8％) developed neutropenia.There were no deaths during hospitalization.Conclusion Patients with KD has become more and more in Wenzhou.Cardiovascular damages were similar to those in Beijing and Guangzhou,but higher than that reported in Japan.

Objective: To investigate the clinicopathologic features of cardiac myxofibrosarcomas. Methods: The clinical data, pathomorphologic and immunohistochemical features were evaluated in five cases of cardiac myxofibrosarcoma collected from January 2009 to December 2014, with relevant literature review. Results: Five patients with cardiac myxofibrosarcoma, including four women and one man [age range 39-61 years; mean (50.4±9.0) years] were included. All tumors were broadbased and located mainly in the left atrium, with one case extending through the atrial wall and pericardium to the left lower lung lobe. The morphological grade was low in one case, intermediate in one, and high in three. Using Fédération Nationale des Centres de Lutte Contre le Cancer (FNLCC) grading system, one case was grade 1 and four cases were grade 2. Immunohistochemical analysis revealed diffuse and strong expression for vimentin in all cases. Smooth muscle actin and muscle specific actin were variably expressed. Complete tumor excision was performed in one case, and tumor debulking was performed in the other four cases. Clinical follow-up was available in three cases. One patient with en bloc excision of the tumor mass survived 13 months and the other two with tumor debulking died one month after surgery. Conclusions The most common location for cardiac myxofibrosarcoma is the left atrium. Some myxofibrosarcoma may be histologically bland and misdiagnosed as myxoma due to histological similarities. Thus caution should be exercised in their microscopic differentiation. Precise imaging, multidisciplinary approach and adequate initial surgery may contribute to improving the clinical outcomes of myxofibrosarcoma.

Objective:To investigate the application effects of non-invasive ultrasound cardiac output monitoring (USCOM) in fluid resuscitation guidance and hemodynamic evaluation of patients with sepsis.Methods:A total of 80 patients with sepsis who were treated in The Second Hospital of Jiaxing from January 2021 to December 2022 were included in this single-blind randomized controlled study. These patients were randomly divided into a control group ( n = 40) and an observation group ( n = 40). In the control group, continuous cardiac output indicated by pulse waveform monitoring was used to guide fluid resuscitation and monitor hemodynamic status, while in the observation group, USCOM was used to guide fluid resuscitation and monitor hemodynamic status. The fluid intake and outflow at 24, 48, and 72 hours after admission to the ICU were compared between the two groups. The changes in arterial blood lactate and oxygenation index at 1, 2, 3, 5, and 7 days after admission to the ICU were compared between the two groups. The time of admission to ICU, the length of ICU stay, and changes in hemodynamic indicators were compared between the two groups. The incidence of death within 28 days after admission to the ICU was compared between the two groups. Results:The liquid intake and output in the observation group at 24, 48 , and 72 hours after admission to the ICU were (4 178.13 ± 327.19) mL, (7 763.63 ± 324.08) mL, and (10 501.38 ± 376.74) mL, respectively, which were significantly lower than (4 527.35 ± 276.84) mL, (8 778.15 ± 361.42) mL, and (11 589.12 ± 413.27) mL in the control group ( t = 5.15, 13.22, 12.30, all P < 0.001). The arterial blood lactate levels in the observation group were significantly lower than those in the control group at 1, 2, 3, 5, and 7 days ( t = 5.73, 6.73, 9.98, 12.25, 14.47, all P < 0.001). There was no significant difference in oxygenation index between the two groups on the 1 st day ( P > 0.05). The oxygenation index in the observation group at 2, 3, 5 and 7 days was significantly higher than that in the control group ( t = -4.31, -8.19, -5.28, -9.44, all P < 0.05). The time of admission to ICU and the length of ICU stay in the observation group were (10.15 ± 2.43) days and (16.51 ± 1.36) days, respectively, which were significantly shorter than (12.75 ± 2.87) days and (17.68 ± 1.59) days in the control group ( t = 4.37, 3.54, both P < 0.05). After 24 hours of resuscitation, cardiac output, stroke output, and cardiac index in the observation group were (5.89 ± 0.51) L/min, (57.71 ± 3.82) mL, and (3.31 ± 0.35) L·min -1·m -2, respectively, which were significantly higher than (5.30 ± 0.37) L/min, (50.06 ± 3.25) mL, and (2.85 ± 0.34) L·min -1·m -2 in the control group ( t = -5.92, -9.65, -5.96, all P < 0.001). There was no significant difference in the 28-day mortality rate between the two groups ( P > 0.05). Conclusion:The guidance of USCOM on fluid resuscitation and hemodynamic status assessment in sepsis patients has an obvious effect, which can promote the improvement of patient oxygenation index, and shorten the time of admission to the ICU and the length of hospital stay.

Objective To investigate the diagnostic value of the medial plantar nerve in diabetic peripheral neuropathy(DPN).Methods A retrospective analysis was conducted in 114 patients with type 2 diabetes mellitus in our hospital.All the participants were divided into DPN group(n=73)and type 2 diabetes mellitus(T2DM)group(n=41)based on the presence of peripheral nerve damage.Simultaneously,35 healthy volunteers were chosen as the normal control(NC)group.General data,biochemical indexes,medial plantar nerve amplitude,conduction velocity,and abnormal rates were compared among the three groups.DPN patients were further divided into symptomatic and asymptomatic groups based on the presence of plantar paresthesia symptoms.The abnormal rate of the medial plantar nerve was compared with that of the superficial peroneal nerve and sural nerve in each group.Receiver operating characteristic(ROC)curve analysis was employed to assess the diagnostic value of the medial plantar nerve in DPN.Results The amplitude of the medial plantar nerve was significantly lower[(3.00±1.42)vs(6.64±3.76)vs(6.51±3.58)μV],the conduction velocity was markedly reduced[(46.57±7.42)vs(49.42±6.96)vs(51.22±5.34)m/s],and the abnormality rate was elevated(87.67%vs 12.20%)in T2DM group,than in NC groups(P<0.05).Spearman correlation analysis indicated a negative correlation between the medial plantar nerve amplitude and HbA1c(r=-0.267,P<0.05),while the conduction velocity showed a negative correlation with age(r=-0.157,P<0.05).In both symptomatic and asymptomatic DPN patients,the abnormal rate of the medial plantar nerve was higher than that of the superficial peroneal nerve and sural nerve(P<0.05).The area under the ROC curve was 0.942,signifying a reliable diagnostic value for DPN using the medial plantar nerve(P<0.05).Conclusions The medial plantar nerve proves valuable in the diagnosis of DPN,exhibiting higher sensitivity than the superficial peroneal nerve and sural nerve.

OBJECTIVETo improve the diagnostic accuracy of fetal pulmonary venous abnormalities through the analysis of the fetal pulmonary vein anatomy.

METHODS234 cases of congenital cardiac abnormalities were detected by echocardiography during pregnancy in An Zhen Hospital, Capital Medical University from May 2010 to August 2015. Autopsy was then performed. The type of fetal pulmonary venous malformation, cardiac abnormalities, systemic venous malformations, and other internal organs deformities were documented.

RESULTSThere were ninteen cases of pulmonary venous malformations among the 234 cases of fetal congenital heart disease. These included two cases of congenital pulmonary venous hypoplasia (CPVH) or atresia, four cases of partial anomalous pulmonary venous drainage (PAPVD), seven cases of total anomalous pulmonary venous drainage (TAPVD), five cases of atresia of common pulmonary vein (CPV), one case of congenital pulmonary venous hypoplasia with total anomalous pulmonary venous drainage. There were eleven cases with single ventricle, eight cases with right aortic arch, seven cases with single atrium and six cases with pulmonary valve stenosis. Eleven cases had pulmonary hypoplasia and nine cases had abnormal spleen.

CONCLUSIONSThere are many variations in pulmonary venous abnormalities associated with severe and complex cardiac abnormalities and internal organs malformation. Care should be exercised during autopsy examination to look for all branches of the pulmonary vein.
