Objective:To evaluate the diagnostic value of cardiac magnetic resonance (CMR) in myocardial contusion.Methods:A case-control study was performed on 42 patients with blunt chest injury treated in Affiliated Hospital of Hangzhou Normal University from September 2018 to January 2021. There were 24 males and 18 females, with the age range of 23-66 years [(44.2±10.9)years]. The patients were divided into myocardial contusion group ( n=20) and non-myocardial contusion group ( n=22) according to the clinical diagnostic criteria of myocardial contusion (cardiac troponin I>0.06 ng/ml). All the patients underwent CMR examination within 7 days after hospitalization, and eletrocardiography (ECG) as well as transthoracic echocardiography (TTE) examinations with 24 hours. Abnormal findings on CMR, ECG and TTE were compared between the two groups. The receiver operating characteristic (ROC) curve was used for the comparison of the diagnostic efficacy of CMR, ECG and TTE for myocardial contusion. The area under the curve (AUC), sensitivity, specificity, positive predictive value and Youden index of CMR, ECG and TTE were calculated, respectively. Results:There were 15 patients (75%) presenting CMR abnormalities in myocardial contusion group compared to 2 patients (9%) in non-myocardial contusion group ( P<0.01). CMR abnormalities mainly included myocardial oedema, ischemia or hemorrhage, which were located in the left ventricle of 12 patients (71%), right ventricle of 3 (18%) and ventricular septal of 3 (12%). There were 12 patients (60%) showing ECG abnormalities in myocardial contusion group compared to 7 patients (32%) in non-myocardial contusion group ( P>0.05). Abnormal ECG changes included 8 patients (42%) with sinus tachycardia or bradycardia, 5 (26%) with ST-T changes, 3 (16%) with atrial premature beat, 2 (11%) with bundle branch block and 1 (5%) with frequent premature ventricular contractions. There were 10 patients (50%) showing TTE abnormalities in myocardial contusion group compared to 9 patients (41%) in non-myocardial contusion group ( P>0.05). TTE abnormalities manifested as left ventricular diastolic dysfunction in 12 patients (63%) and wall motion abnormalities in 7 (37%). The AUC of CMR, ECG and TTE for diagnosing myocardial contusion was 0.83 (95% CI 0.70-0.96), 0.64 (95% CI 0.47-0.81) and 0.55 (95% CI 0.70-0.72), respectively. For CMR, ECG and TTE, the diagnostic sensitivity was 75.0%, 60.0% and 50.0%, with the specificity of 91.0%, 68.2% and 59.1%, the positive predictive value was 88.2%, 63.2% and 52.6%, and the Youden index of 66.0, 28.2 and 9.1, respectively. Conclusion:CMR can accurately detect myocardial contusion, with better diagnostic performance than ECG and TTE as well as relatively higher sensitivity and specificity, indicating that CMR has great value for clinical diagnosis of myocardial contusion.

Objective:To explore the clinical effect of a two-staged repair and reconstruction of composite soft tissue defect of dorsal wrist with transfer of free flap (in stage-one) repair and followed by transplantation of allogeneic tendon (in stage-two) reconstruction.Methods:From December 2018 to January 2021, 6 cases with dorsal wrist composite tissue injury and extensor tendon defect were treated in the Department of Hand and Microsurgery of the Fourth People's Hospital of Guiyang City. Four cases were treated with free anterolateral thigh flap (ALTF) combined with allogeneic tendon in the first stage to reconstruct finger dorsiflexion function, and 2 cases were treated with free ilioinguinal flap combined with allogeneic tendon in the second stage to reconstruct finger dorsiflexion function. The age of the patients ranged from 22 to 62 years old. The areas of defect were 5.0 cm×12.0 cm-8.0 cm×20.0 cm. Two cases had 2 extensor tendons defect, 1 had 3 extensor tendons defect, 2 had 4 extensor tendons defect, and 1 had 5 extensor tendons defect. The length of extensor tendon defects was 7.0-22.0 cm. In 5 cases, the wounds were covered by VSD for 5 to 7 days after complete emergenly debridement. Then, after the wounds had been cleared and clean, the wounds of 3 cases were covered with free ALTF, 2 with free ilioinguinal flap, and 1 with free ALTF after skin graft scar resection. At 3-4 months later, the extension function of digit was reconstructed with the transplantation of allogeneic tendons. Postoperative appearance of the flaps and functions of digits were observed at the outpatient clinics during the follow-up.Results:The postoperative follow-up lasted for 10 to 26 (15 in average) months. All 6 flaps surrived completely, and 1 case was further treated with flap thinning at 4 months after the second surgery. During the follow-up, all flaps healed well and were good in appearance and texture. Meanwhile, the donor areas were all healed well with no dysfunction nor sensory disorder. All the transplanted tendons were in good glide without adhesion. The active motion of metacarpophalangeal joints ranged from (10±10) ° to (80±10) °. According to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, at the final follow-up, 4 cases were excellent and 2 cases were good.Conclusion:It is safe and effective that using the two-staged procedure in repair of composite tissue defect of dorsal wrist with stage-one ALTF or ilioinguinal flap transfer combined with stage-two reconstruction with transplantation of allogeneic tendon. It can minimize the adhesion after tendon transplantation and donor site damage

Objective:To investigate ultrasonographic manifestations of gonococcal infections of the penile skin and accessory glands in men, and to assess their clinical significance.Methods:From January 2014 to January 2021, male patients with gonococcal infections of the penile skin and accessory glands were collected from Department of Dermatology, Changshu No.1 People′s Hospital. The diagnosis had been confirmed by laboratory examinations, and these patients had not received relevant treatment. The real-time ultrasound imaging system SIEMENS ACUSON X300 was used to examine the penile skin and accessory gland lesions infected with Neisseria gonorrhoeae, with the probe frequency ranging from 7.5 to 15 MHz. Patients with tubular anechoic fluid-filled areas on the high-frequency ultrasound images received a single dose of intramuscular ceftriaxone (1 g) ; those with oval-shaped anechoic fluid-filled areas on the high-frequency ultrasound images received incision and drainage followed by intramuscular injection of ceftriaxone at a dose of 1 g once a day for 5 consecutive days; those with hypoechoic or mixed echoic areas on the high-frequency ultrasound images received intramuscular injection of ceftriaxone at a dose of 1 g once a day for 5 consecutive days, and if the nodules did not regress after 1-month treatment, local resection would be performed. One month after the treatment, the patients were followed up, and the efficacy was evaluated. Results:A total of 32 male patients with gonococcal infections of the penile skin and accessory glands were collected. They were aged 28.54 ± 3.27 years, all had a history of non-marital sexual contact, and the duration from non-marital sexual contact to the onset of symptoms was 4.45 ± 1.03 days. The disease course was 8.64 ± 1.87 days. Lesions were all solitary, and located at the external urethral meatus in 16 cases (50.00%) , at the glans penis in 7 cases (21.88%) , beside the foreskin frenulum in 5 cases (15.62%) , and at the penile raphe in 4 cases (12.50%) . Sixteen patients (50.00%) presented with sinus-like lesions, 9 (28.13%) with abscesses, 7 (21.87%) with nodules, and all had tenderness on palpation. High-frequency ultrasound examination showed tubular anechoic fluid-filled areas in 16 cases (50.00%) , oval-shaped anechoic fluid-filled areas in 7 cases (21.88%) , hypoechoic areas in 5 cases (15.62%) , and mixed echoic areas in 4 cases (12.50%) . Gonococcal infections involved the cavernous body of the urethra in 16 cases (50.00%) , cavernous body of the penis in 5 cases (15.62%) , and subcutaneous tissue of the penis in 11 cases (34.38%) . After the treatment, all the patients were cured.Conclusion:High-frequency ultrasound can be used in the assessment of skin lesions and selection of treatment regimens for male patients with gonococcal infections of the penile skin and accessory glands.

Background The metabolites and metabolic pathways of hand-arm vibration syndrome have not yet been elucidated. Objective To investigate the effect of local vibration on endogenous metabolites in rat serum by metabolomic analysis, to preliminarily explore the potential metabolic pathway of endogenous metabolites, so as to provide evidence for further research on the mechanism of hand-arm vibration syndrome. Methods Thirty-two SPF male SD rats, (211.3±11.1) g, 7−8 weeks of age, were selected and randomly divided into three groups: control group (14 rats, without vibration), 7 d vibration group (9 rats, continuously vibration for 7 d), and 14 d vibration group (9 rats, continuous vibration for 14 d). The vibration rats were vibrated every day for 4 h, the frequency weighted acceleration was 4.9 m·s−2, the vibration frequency was 125 Hz, and the vibration direction was one-way vertical vibration. The control group had the same conditions except not contacting vibration. After the vibration exposure, the blood samples taken from the abnormal aorta of rats were collected, and the changes of rat serum metabolome were analyzed by ultra-performance liquid chromatography-tandem time-of-flight mass spectrometry. Principal components analysis (PCA) was used to explore changes in rat serum metabolic profile, and orthogonal partial least squares-discriminant analysis (OPLS-DA) was used to screen out differential metabolites. Combined with online databases, a metabolic pathway enrichment analysis of differential metabolites was performed. Results The PCA analysis showed that compared with the control group, the rat serum metabolic profiles in the 7 d group and the 14 d group were clearly differentiated, and the rat serum metabolic profiles in the 7 d group and the 14 d group partially overlapped. The OPLS-DA analysis showed significant differences between groups. The main parameters were: model interpretation rate R2Y=0.914, model predictive ability Q2=0.58. The OPLS-DA analysis screened out 26 and 119 differential metabolites from the 7 d group and the 14 d group respectively, and there were 24 common differential metabolites between the 7 d group and the 14 d group. The metabolomic pathway analysis showed that local vibration-induced changes in rat serum metabolism were mainly related to arachidonic acid metabolism in the 14 d group, among which the metabolites with significant effects were arachidonic acid, prostaglandin E2, and prostaglandin D2. Conclusion Local vibration could affect the normal metabolism in rats, and the metabolic pathway with significant influence is arachidonic acid metabolism after a 14 d exposure and the involved metabolites are arachidonic acid, prostaglandin E2, and prostaglandin D2.
