ABSTRACT

Objective:To investigate the surgical technique and clinical effect of the island flap of dorsal branch of proper palmar digital artery in repair of the soft tissue defect of digits.Methods:From March 2013 to March 2021, 22 cases of digit soft tissue defects were repaired with dorsal branch of proper palmar digital artery island flap. The digit defects involved: 9 thumbs, 5 index fingers, 3 middle fingers, 3 ring fingers and 2 little fingers. The repair of defects covered 8 digit-tips, 7 pulps and 7 dorsal and nail beds. The defected area of soft tissue was 0.8 cm×0.5 cm-1.5 cm×8.0 cm, and the size of flap was 1.0 cm×0.7 cm-1.8 cm×1.0 cm. The donor site in 6 cases was closed directly. The other 16 cases were covered with medium thickness skin graft and pressurised bandaging. The follow-up reviews were carried out via the outpatient clinic visit, telephone or WeChat interview. Results:After operation, 1 flap had cyanosis due to a tight suture and it was relieved after the removal of intermittent suture; Tension blisters appeared in 2 cases and disappeared after 1 week; One case had necrosis at distal flap and healed after dressing change. Other flaps survived successfully and the incision and donor site healed in the first stage. All patients were entered to 6 to 18(mean 10) months of follow-up. At the final follow-up, the appearance and texture of the flaps were good and the protective sensation was restored. The flexion and extension function of the affected digit was normal with the TPD at 7-11 mm. The original shape and function of the digit body were basically reconstructed, except the failure in reconstruction of the special structure of digit body, such as nail, finger pulp thread and fine sensation. According to the Evaluation Standard of Upper Limb Function of Chinese Hand Surgery Society, 11 cases were in excellent, 9 in good and 2 in fair. The excellent and good rate was 91%. The function at donor sites was not affected.Conclusion:Repair of digit soft tissue defect with dorsal branch of proper palmar digital artery island flap is easy to operate, and with a low risk, high success rate and satisfactory curative effect.

ABSTRACT

Objective:To evaluate the feasibility, safety and efficacy of the magnetic resonance imaging guided focused ultrasound surgery (MRgFUS) in the treatment of localized prostate cancer (PCa).Methods:The data of 5 patients treated by MRgFUS from August 2020 to June 2021 in our institution were retrospectively analyzed. The median age was 73 (58-80) years, with the median PSA of 7.34 (5.19-8.40) ng/ml, and a median prostate volume of 27.96 (21.50-37.91) ml. The median pretreatment international prostate symptom score (IPSS) was 13(0-18). Of the 3 patients with intention of erectile function preservation, the pretreatment international index of erectile function-15 (IIEF-15) score was 12, 23 and 3, respectively. All patients had histopathology-proven PCa of grade group ≤ International Society of Urological Pathology (ISUP) 3, pre-operative PSA level <20 ng/ml, and a clinical stage ≤T 2b. A total of 6 lesions was confirmed by biopsy, with 3 of ISUP grade group 3 and 3 of ISUP grade group 1. All 5 patients underwent MRgFUS which was guided by a real-time magnetic resonance imaging (MRI). PSA, MRI and repeated biopsy were conducted to monitor recurrence. Questionnaires consisted of IPSS, IIEF-15, and the International Consultation on Incontinence-questionnaire-Short Form (ICI-Q-SF) were recorded before and after MRgFUS to evaluate the impact on functional preservation. Results:A total of 5 patients received MRgFUS. In total, 5 of the 6 lesions were treated. 1 lesion unvisible on MRI was not clinically significant and was left untreated. The median time in MRI scanner was 190 (140-355) min, and the median sonication time was 64 (35-148) min with the median sonications of 8 (5-13). The median catheter indwelling time was 1 (1-8) days. No other adverse effects were reported. The PSA level of all 5 patients decreased, with the nadir PSA of 1.196 ng/ml, 4.398 ng/ml, 4.135 ng/ml, 1.562ng/ml and 1.350ng/ml, respectively. 4 of the patients had a PSA decrease over 50%. No PCa lesion was seen on MRI at 3-month follow-up visit. As for functional preservation, the post-MRgFUS IPSS declined compared with the baseline score, and the IPSS of last follow-up was 5(0-14). Of the 3 patients with intention to preserve the erectile function, the erectile function score of IIEF-15 were 12, 30 and 9 three months after the treatment, respectively. No incontinence occurred postoperatively.Conclusions:MRgFUS is a feasible and safe way for the treatment of low- to intermediate-risk localized PCa, with satisfactory performance on functional preservation and low incidence of complications. The oncological outcomes still need to be establised with longer follow-up time and larger sample studies.

ABSTRACT

Objective:To investigate the diagnostic value of quantitative parameters of synthetic MRI in patients with prostate cancer (PCa).Methods:From April 2018 to April 2019, 25 PCa patients confirmed by whole-mount pathology were prospectively enrolled in Beijing Hospital. All patients underwent prostate MRI examinations including DWI and synthetic MRI. Four kinds of tissue types were identified in pathology, including PCa, stromal hyperplasia (SH), glandular hyperplasia (GH) and prostatitis. According to the pathological results, quantitative parameters including ADC, T 1, T 2 and proton density (PD) values were measured on DWI and synthetic MRI. One-way analysis of variance or Kruskal-Wallis H test was performed to compare the difference of each parameter among PCa, SH or GH in the transitional zone (TZ). The difference of each parameter between PCa and prostatitis in the peripheral zone (PZ) was evaluated by using independent sample t test or Mann-Whitney U test. The diagnostic performance of each parameter in discriminating PCa from other benign conditions was evaluated by using ROC curve. Area under the curve (AUC) of each parameter was compared by using DeLong test. Results:The overall differences of T 1, T 2 PD and ADC values were statistically significant among PCa and other benign conditions. The T 1, T 2 and ADC values of PCa in the TZ were lower than those in the SH ( P=0.041, 0.030,<0.001) and GH (all P<0.001). The PD value of PCa in the TZ was lower than that in the GH ( P=0.040). The differences of T 1, T 2, PD and ADC values between PCa and prostatitis in the PZ were significant ( P<0.05). The AUC of ADC value (0.943) was higher than that of T 1 (0.691, P=0.001), PD (0.555, P=0.002) and T 2 (0.754, P=0.016) values in differentiating PCa from SH. For discriminating PCa and GH, T 1, T 2 and ADC showed similar AUC ( P>0.05), which were higher than AUC of PD value ( P=0.001). For discriminating PCa and prostatitis, T 1, T 2, PD and ADC values showed similar AUC ( P>0.05). Conclusions:Quantitative parameters of synthetic MRI were practical tools for discriminating PCa from other benign pathologies.

ABSTRACT

Objective:To investigate the relationship between atherosclerotic plaque characteristics of the middle cerebral artery(MCA)and acute cerebral ischemic symptoms by using high-resolution magnetic resonance imaging(HR-MRI).Methods:A retrospective analysis of clinical and imaging data was performed in 136 patients[100 males, aged(60.8±11.4)years]with MCA atherosclerotic plaque who underwent HR-MRI.Patients were divided into the acute symptomatic group(n=73)and the non-acute asymptomatic group(n=63)according to whether the patients had acute ischemic symptoms in the MCA territory within two weeks.The basic demographic characteristics, clinical risk factors, MCA plaque enhancement, maximum plaque length, maximum wall thickness, ratio of maximum plaque length to maximum wall thickness and luminal stenosis were compared between the two groups.Binary Logistic regression was used to estimate the association between MCA plaque characteristics and acute ischemic symptoms in the corresponding vascular territory.Results:Compared with the non-acute symptomatic group, the acute symptomatic group had a greater prevalence of diabetes mellitus(50.7% or 30/73 vs. 30.2% or 19/63, χ2=5.882, P=0.015), a higher occurrence of enhanced plaques(87.7 % or 64/73 vs.46.0% or 29/63, χ2=27.118, P<0.001), greater maximum plaque length[(6.7±3.7 mm) vs.(4.9±2.3)mm, t=-3.330, P=0.001], greater maximum wall thickness[(1.5±0.8)mm vs.(1.0±1.0)mm, t=-2.231, P=0.027]and more severe luminal stenosis[(66.4±31.3)% vs. (30.7±25.3) %, t=-7.354, P<0.001]. Logistic regression analysis showed that MCA enhanced plaque( OR=4.492, 95% CI: 1.762-11.449, P=0.002)and luminal stenosis( OR=1.032, 95% CI: 1.018-1.047, P<0.001)were independently associated with acute ischemic symptoms. Conclusions:Compared with luminal stenosis, MCA enhanced plaque has a stronger correlation with acute ischemic symptoms and significant plaque enhancement may be an important indication of its instability.

ABSTRACT

Objective@#To investigate the value of zTE ASL MRA in the follow-up of interventional treatment of intracranial aneurysm at 1.5 T, using DSA as gold standard.@*Methods@#Patients with intracranial aneurysms who underwent coil embolization with or without stent were enrolled in this study. Both TOF MRA and zTE ASL MRA were performed on a 1.5T whole body scanner (MR360, GE, USA) equipped with an 8 channel head coil, and DSA was performed within one week of the MR examinations. Aneurysmal remnant and intra-stent opacity were analyzed. SE, PE, PPV, NPV of two MRA modalities in aneurysm recanalization detection were calculated. Kappa coefficient was used to determine the inter-reader and intra-reader reproducibility. Paired t test was used to test the visibility of in-stent lumen on two kinds of MRA.@*Results@#A total of 24 patients (27 aneurysms) were included in this study, 23 aneurysms were treated with stent assisted embolization, four coil embolization. Thirteen cases of aneurysm remnant were detected by DSA, 15 by zTE ASL and 11 by TOF MRA. zTE ASL MRA had a relatively higher SE (100%) and NPV(100%) as compared with TOF MRA. The Kappa value in identification of aneurysm remnant was 0.85 between zTE MRA and DSA and 0.70 between TOF MRA and DSA, respectively. The inter-reader reproducibility was good (Kappa 0.70), while the intra-reader reproducibility was excellent(Kappa 0.85). There was statistical significance in the scoring results of the in-stent lumen visibility.@*Conclusion@#zTE ASL MRA proved to be a better imaging modality as compared to TOF MRA to evaluate the endovascular treatment effectiveness of intracranial aneurysms, especially for assessing the aneurysmal recurrence and in-stent lumen visibility.

ABSTRACT

Objective To investigate the relationship between neutrophil ratio/blood glucose and short outcome among patients with acute ischemic stroke admitted to hospitals.Methods A total of 2 265 acute ischemic stroke patients in four hospitals in Shandong province were included in this study.Through access to patients' files,data on demographic,lifestyle,medical history,family history and laboratory findings were collected from all participants at admission.Endpoint of the study was defined as poor short-term prognosis of acute cerebral infarction (NIHSS≥5) at discharge or death during hospitalization.Subjects of this study were divided into four groups:normal neutrophil ratio with normal blood glucose (NN/NG) ;normal neutrophil ratio with high blood glucose (NN/IG) ;high neutrophil ratio with normal blood glucose (IN/NG) and high neutrophil ratio with high blood glucose (IN/IG).Non-conditional logistic regression analysis was used to evaluate the association between blood glucose/neutrophil ratio and the short outcome of acute ischemic stroke.Results Neutrophil ratio and the level of blood glucose in patients with study endpoints were both higher than those without the study endpoints,and the difference was statistically significant (all P<0.05). After multivariate adjustment,when compared to NN/NG group,the ORs (95% CI) of NN/IG,IN/NG and IN/IG group were 1.356 (0.942-1.953),1.879 (1.113-3.171) and 2.210 (1.477-3.307),respectively.Conclusion Neutrophil ratio at admission was an independent risk factor of poor short outcome in patients with acute ischemic stroke.IN/IG group was considered at a highest risk in general population.Neutrophil ratio/glucose was valuable in predicting the incidence of poor short outcome in acute ischemic stroke patients.

ABSTRACT

Objective To analyse factors associated with onychomadesis in children,and to evaluate the relationship between onychomadesis and hand-foot-mouth disease (HMFD).Methods A retrospective study was performed.Clinical data were collected from 120 children with onychomadesis (average age,3.19 ± 2.06 years) and 120 sex-and age-matched patients with hemangioma.Viral detection was realized by real-time reverse transcriptionPCR in throat swab specimens.Data were analyzed by chi-square test using the SPSS 16.0 software.Results Of the 120 patients with onychomadesis,85 (70.83%) had a history of HMFD,which was 4 to 8 weeks prior to the occurrence of onychomadesis.Onychomadesis was strongly correlated with HMFD (OR,7.621,95% CI,4.292-13.531),but uncorrelated with the occurrence and peak of fever,abnormality of serum trace elements,existence of latent diseases,or the use of antipyretic drugs or antimicrobial drugs during the clinical course of HMFD (all P >0.05).Several viruses were detected in 39.7% of 68 throat swab specimens from patients with HMFD accompanied by onychomadesis,which included Coxsackievirus A16 in 9 patients,enterovirus 71 in 3 patients and unidentified enteroviruses in 15 patients.Conclusion Onychomadesis appears to be a complication of HMFD.

ABSTRACT

BACKGROUND: Experimental autoimmune encephalomyelitis has become the most classical animal model for multiple sclerosis. However, the experimental autoimmune encephalomyelitis model of China presented one-way course of disease. By using proteolipid protein 139-151 and proteolipid protein 178-191, relapse remitting experimental autoimmune encephalomyelitis models may be induced in SJL/J mice which were susceptible to immune, which have similar clinical situation, course and histologicallterations to multiple sclerosis.OBJECTIVE: To establish the relapse remitting experimental autoimmune encephalomyelitis mouse model induced by proteolipid protein, which has similar clinical situation, course and histological alterations to multiple sclerosis.DESIGN: Completely randomized controlled study.SETTING: The centre of Neuro-information, and Neurological Institute,General Hospital of Chinese PLA.MATERIALS: The study was carried out at the Laboratory of Neuro-pathology, General Hospital of Chinese PLA, from February to June 2004.Sixty female SJL/J mice with 8-12 weeks old were selected and randomly divided into proteolipid protein 139-151 group and proteolipid protein-178-191 group with 30 in each.INTERVENTIONS: After injected with proteolipid protein-139-151 or proteolipid protein-178-191, the models of relapse remitting experimental autoimmune encephalomyelitis were induced, and the body weight and neurological signs of each female SJL/J mouse were viewed. The tissue morphological changes of models were observed with hematoxylin and eosin and uxol fast blue stain.MAIN OUTCOME MEASURES: The neurological symptoms and signs,features of relapse and remitting and the perivascular inflammatory cell infiltration, demyelinated lesion of the model of experimental autoimmune encephalomyelitis mouse induced by two proteolipid protein peptides.RESULTS: All 60 mice entered the final analysis. ① Significant neurological symptoms, signs and features of relapse and remitting was manifested in the model of experimental autoimmune encephalomyelitis mouse induced by two proteolipid protein peptides. Obvious phenomena of perivascular inflammatory cuffing, satellitism, predominant perivascular inflammatory cell infiltration and demyelinated lesion were found in spinal and cerebral tissue. ②Changes of body mass: Before immunity, the body mass of mice in two groups was( 17. 84 ± 2.59) g and (17. 88 ± 0.52) g respectively. Onset of relapse of the mice in proteolipid protein-178-191 group was earlier and faster, their body mass had no distinctive change after immunization and the mean body mass was(23.52 ± 2.37) g till the 60th day. Meanwhile, Onset of relapse of the mice in proteolipid protein-139-151 group was later and slower. After the immunity, the body mass of mice was little decrease, and the body mass was (16. 70 ±0.46) g on the 60th day. ③ Neural functional scores: The highest functional scores in the two groups were not different(3.86 ± 1.10vs 3.71 ±1.05, t=0.49, P=0.628).CONCLUSION: The two different antigenic peptides of proteolipid protein can all cause the autoimmune response of central nervous system. Both models have the same characters of relapse and remitting and the severity has no significant difference. But compared with proteolipid protein 139- 151 group,onset and recover of the experimental autoimmune encephalomyelitis of the mice in proteolipid protein 178-191 group were earlier, as well as weight variance was larger, which maybe due to the different structure of two peptides.

ABSTRACT

Objective To study the protective effect and molecular mechanism of trypsin inhibitor on reperfusion injury after cerebral ischemia. Methods The model of ischemia for 1h and repufusion for 24h of rat cerebrum was set by ligating MCAO described by zea-longa. 24 male rats were divided randomly into the sham operation group, the control group and trypsin inhibitor group. The presence of neurological function deficit was measured by Zea-Longa method, and the immunohistochemical staining and TUNEL were used to detect p53 protein expression and cell apoptosis in the brain tissues respectively. Results The score of neurological function deficit was zero in the sham operation group, 2 8?1 0 in the control group and 1 3?0 7 in trypsin inhibitor group. There were 12 3?2 5 p53 immunostaining positive cells in the control group and 5 5?1 3 in trypsin inhibitor group. The number of apoptotic cells was zero in the sham operation group, 7 6?1 0 in the control group, and 3 5?0 9 in trypsin inhibitor group. There was a significant difference in all above observing indices between the control group and trypsin inhibitor group(P
