Objective To explore the characteristics of myocardial injury in patients with acute myocardial infarction(AMI)complicated by pleural effusion and its effect on long-term prognosis.Methods It was a prospective single-center study.Patients with AMI who were admitted to hospital within 15 days from symptom onset and performed echocardiography and cardiac magnetic resonance imaging(CMR)during hospitalization were consecutively enrolled and assigned to the with-pleural effusion group and the without-pleural effusion group according to the echocardiography result.Baseline data,cardiac magnetic resonance myocardial injury index and echocardiography characteristics were compared between the two groups.The occurrence of major adverse cardiovascular and cerebrovascular events(MACCE)was recorded through outpatient follow-up and telephone follow-up,including all-cause death,re-infarction,revascularization,rehospitalization for congestive heart failure and stroke.Cox regression analysis was performed to analyze influencing factors of all-cause death.Results Among 211 patients,31(14.7%)patients had pleural effusion and 180(85.3%)had no pleural effusion.Compared with the group without pleural effusion,the left ventricular end-diastolic diameter was larger,and left ventricular ejection fraction assessed by echocardiography was lower in the group with pleural effusion(P＜0.05).There were no significant differences in infarct size,left ventricular end-diastolic volume,left ventricular end-systolic volume,left ventricular ejection fraction and the presence of microvascular obstruction and intramyocardial hemorrhage between the two groups in CMR(all P＞0.05).At a median follow-up of 31 months,MACCE occurred in 43(20.4%)patients,and there was no significant difference between the two groups(χ2=3.160,P=0.075).Six cases(2.8%)had all-cause death.The incidence of all-cause death was higher in the group with pleural effusion than that in the group without pleural effusion(9.7%vs.1.7%,P<0.05).There was no significant difference in the incidence of other adverse events between the two groups(P＞0.05).Multivariate Cox regression analysis showed that advanced age and presence of pleural effusion were independent risk factors of all-cause death during follow-up.Conclusion Patients with AMI combined with pleural effusion have more severe myocardial injury and higher all-cause mortality.

To examine the feasibility of using a computer tool for stratifying the severity of Coronavirus Disease 2019 (COVID-19) based on computed tomography (CT) images. We retrospectively examined 44 confirmed COVID-19 cases. All cases were evaluated separately by radiologists (visually) and through an in-house computer software. The degree of lesions was visually scored by the radiologist, as follows, for each of the 5 lung lobes:0, no lesion present;1,<1/3 involvement;2,>1/3 and<2/3 involvement;and 3,>2/3 involvement. Lesion density was assessed based on the proportion of ground-glass opacity (GGO), consolidation and fibrosis of the lesions. The parameters obtained using the computer tool included lung volume (mL), lesion volume (mL), lesion percentage (％), and mean lesion density (HU) of the whole lung, right lung, left lung, and each lobe. The scores obtained by the radiologists and quantitative results generated by the computer software were tested for correlation. A Chi-square test was used to test the consistency of radiologist- and computer-derived lesion percentage in the right/left lung, upper/lower lobe, and each of the 5 lobes. The results showed a strong to moderate correlation between lesion percentage scores obtained by radiologists and the computer software (r ranged from 0.7679 to 0.8373, P < 0.05), and a moderate correlation between the proportion of GGO and mean lesion density (r=-0.5894, P<0.05), and proportion of consolidation and mean lesion density (r=0.6282, P<0.05). Computer-aided quantification showed a statistical significant higher lesion percentage for lower lobes than that assessed by the radiologists (x2 = 8.160, P = 0.004). Our experiments demonstrated that the computer tool could reliably and accurately assess the severity and distribution of pneumonia on CT scans.

Objective To analyze and compare the incidence of postoperative complications of acute gangrene appendicitis after laparotomy and laparoscopic surgery.Methods This study retrospectively analyzed of 162 cases of acute gangrenous appendicitis treated in Xilin Guole Meng Hospital from January 2015 to January 2018.There were 96 male patients and 66 female patients;age (43.40 ± 16.21) years.According to different surgical methods,162 patients were divided into two groups:laparoscopic group (n =80) and open group (n =82).Laparoscopic appendectomy was performed in the laparoscopic group,and open appendectomy was performed in the open group.To compare the postoperative complications intraoperative and postoperative data between the two groups.It consists of tump fistula or bead inflammation,postoperative pneumonia,abdominal hemorrhage,deep venous thrombosis,incisional hernia,subcutaneous emphysema,incision infection,intestinal obstruction,celiac sepsis,complained of pain intensity classification method for pain score and antibiotic use time,postoperative extubation time,postoperative exhaust time,postoperative bed for the first time for the first time time,length of hospital stay.The measurement data were expressed by (Mean ± SD) and the t test was used with the groups.The counting data were expressed by the percentage or rate and the x2 test was used among the groups.When the number of single group cases was less than 10 cases,the Fisher exact probability method was used for the calibration test.Results The top three complications were incision infection,intestinal obstruction and empyema.The incidence of postoperative complications in open group and laparoscopy group was 65.9％ (54/82) and 8.8％ (7/80) respectively,and there was significant difference between the two groups (F =56.247,P=0.000).The VRS of the lapamscopic group and the open group were 53 points and 12 points for grade Ⅰ,18 points and 36 points for grade Ⅱ,and 9 points and 34 points for grade Ⅲ,The results showed that the difference between the two groups was statistically significant (x2 =2.45,P =0.01).The time of antibiotic use,postoperative tube extraction,postoperative first exhaust,postoperative first time out of bed and hospitalization in the laparoscopic group were respectively (61.2 ±24.2) d,(4.2 ± 1.2) h,(24.6 ±6.9) h,(4.6 ±2.2) h,(5.5 ±3.6) d and the open group were (72±72.6) d,(7.4 ±2.7) h,(52.2 ±4.8) h,(8.4 ±2.6) h,(13.5 ±8.2) d respectively,the differences were statistically significant (P ＜ 0.05).Conclusion The postoperative complications in laparoscopic group were lower than those in open group,so the laparoscopic group was the first choice for the treatment of acute appendicitis,while the open group was another choice for some patients.

Objective To explore the feasibility of the perforator-based intermediate dorsal pedal flap with vessels of cutaneous nerve nutrition for repair of soft tissue defects of the forefoot.Methods A retrospective case series study was performed for seven cases of soft tissue defects of the forefoot hospitalized between February 2013 and January 2017.There were five males and two females,with a mean age of 38 years (range,18-73 years).Injury regions were lateral plantar skin defect in the forefoot in three cases,dorsal skin defect in the third webbed toe in two cases and proximal dorsal skin defect in the fourth toe in two cases.The defect area was about 2.5 cm × 1.5 cm-4.5 cm × 2.0 cm.The perforator-based intermediate dorsal pedal flap with vessels of cutaneous nerve nutrition was designed on the lateral dorsum of the foot and then was incised and transferred to repair the forefoot wound based on its surgical anatomy.The time of surgery and the amount of intraoperative blood loss were recorded.An observation was done on feeling,appearance,texture,blood supply and survival of the flap as well as swelling,hypertrophic scar,itching,paralysis of the skin grafting area.The recovery of the activity function was assessed by American Orthopedic Foot & Ankle Society (AOFAS) score.Results The surgery time was 1.0-1.5 h (mean,1 h),and intraoperative bleeding was about 50 ml (range,30-100 ml).Seven cases of perforator-based dorsal medial skin flap with vessels of cutaneous nerve nutrition all survived,with early wound healing.After 2 to 15 months follow-up,two-point discrimination of flaps was 9-15 mm(average,12.5 mm).Skin flaps were with excellent texture and without swelling,the color of which was close to normal color with good appearance.The postoperative foot did not have bone resorption,wound infection,tendon adhesion,line-type or flaky scar left locally,lower limb walking dysfunction or other complications.Patients were satisfied with the functions of donor and recipient sites and the appearance of the flap.Conclusions Perforation-based dorsal flap with vessels of cutaneous nerve nutrition has high survival rate,satisfaction of appearance and fast recovery of recipient site,with no obvious foot pain,limitation of joint movement or other complications,and therefore is a reliable method to repair soft tissue defects in forefoot.

Objective: To investigate the morphological characters of the dorsal perforators originated from the deep palmar arch, so as to provide anatomic basis for V-Y advanced perforator flap. Methods: The following contents were investigated in 30 adult hand specimens perfused with red latex under surgical magnifier: ①The origin, courses, branches and distribution of the dorsal perforators originatedd from the deep palmar arch. ②The characters of anastomosis among the dorsal perforators, the dorsal carpal and metacarpal arteries. Mimic operation was performed on another fresh specimens perfused with red latex. Results: There were three perforators originated from the deep palmar arch, which passed through the 2nd-4th dorsal interossei and then divided into an ascending branch and a descending branch at the dorsum of hand. Then the ascending branch anastomosed with the dorsal carpal artery, and the descending branch stretched to the 2nd-4th dorsal metacarpal arteries. The originating outer diameters of the 1st-3rd perforators were (1.1±0.2) mm, (0.9±0.3) mm and (0.7±0.1) mm respectively, and the length of the stems were (1.1±0.3) cm, (1.0±0.2)cm and (0.9±0.1) cm respectively. Conclusions The V-Y advanced perforator flap with the dorsal perforator of the deep palmar arch as its vascular pedicle could be used to repair the dorsal carpal or dorsal metacarpal soft tissue defects.
