OBJECTIVE: To propose and evaluate the clinical effect of midpiece facial nerve dissection through transparotid approach in regional parotidectomy. METHODS: A total of 136 patients with benign parotid tumors were categorized into three groups according to the way of facial nerve dissection: anterograde dissection from main trunk (anterograde, n=70), retrograde dissection from distal branches (retrograde, n=34), and midpiece dissection through transparotid approach (middle dissection, n=32). Surgery duration, facial nerve injury, salivary fistula, earlobe sensation, Frey's syndrome, and aesthetic evaluation were compared. RESULTS: The surgery duration in the middle dissection group was significantly shorter than that in the other two groups. The proportion of salivary fistula was higher in the anterograde group (9 cases, 12.9%; P<0.05) compared with that in the other groups. Postoperative facial nerve injury was similar between the middle dissection (1 case, 3.1%) and anterograde groups (3 cases, 4.3%) with lower injury rate compared with the retrograde group (7 cases, 20.6%). The anterograde group had more cases of hypoesthesia of the earlobe (12 cases, 17.1%; P<0.05) than the other two groups. Aesthetic score was higher in the anterograde and middle dissection groups compared with that in the retrograde group (P<0.05). CONCLUSIONS Midpiece facial nerve dissection is technically feasible and clinically viable in regional parotidectomy.

OBJECTIVE: To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study. METHODS: A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA. RESULTS: Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P<0.05), antibiotic exposure during pregnancy (OR=3.18, 95%CI: 1.32-7.65, P<0.05), and the introduction of complementary food at an age of <4 months (OR=3.55, 95%CI: 1.52-8.27, P<0.05) were risk factors for CMPA, while exclusive breastfeeding (OR=0.21, 95%CI: 0.08-0.58, P<0.05) and the introduction of complementary food at an age of >6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors. CONCLUSIONS The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.

BACKGROUND: MAVERIC (Mitral Valve Repair Clinical Trial) validates the safety and efficacy of the ARTO system. We here report the first two successful cases of utilizing the ARTO system in patients with symptomatic heart failure (HF) with functional mitral regurgitation (FMR) in Asia. METHODS: Two patients, aged 70 and 63, had severe HF with FMR. Transesophageal echocardiography confirmed that the left ventricular ejection fractions were less than 50% with severe mitral regurgitation (MR) in both patients. Optimizing drug treatment could not mitigate their symptoms. Therefore, we used the ARTO system to repair the mitral valve for these patients on March 5 and 6, 2019, respectively. RESULTS: Mitral valve repairs using the ARTO system were successfully performed under general anaesthesia for these two patients. MR was decreased immediately after the procedures in both patients. The 30-day and 3-month transthoracic echocardiography (TTE) revealed a moderate to severe MR in both patients, and the New York Heart Association (NYHA) scales were also partially improved. CONCLUSION The first two cases in Asia indicate that the ARTO system is feasible for patients with heart failure with FMR, and the patient selection appears to be crucial.

BACKGROUND: The purpose of this study was to identify the consistency of invasive dynamic blood pressure (BP) monitoring between the superior mesenteric artery (SMA) and the common carotid artery (CCA). METHODS: Eight male Sprague-Dawley rats were cannulated in SMA and CCA simultaneously for BP monitoring, respectively. The abdominal aorta was prepared for the induction of BP change through clamping/de-clamping by a microvascular clip. The dynamic BP monitoring was performed by a polygraph system. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) values would be recorded during different time periods: the baseline (T1), the increasing period after clamping (T2), the platform period during clamping (T3), the decreasing period after de-clamping (T4), and the final platform period (T5). Three trials were performed on each rat with 15-minute intervals between consecutive monitoring. RESULTS: Systolic BP showed no significant differences between SMA and CCA. However, significant difference was found in diastolic blood pressure except at T5 (P=0.534). Mean arterial pressure of two arteries were signifi cantly different only at T1 (P=0.015). The strength of association was significantly high between BP measurements through SMA and CCA (P<0.001). The Bland- Altman analyses showed that mean bias of MAP changed no more than 5 mmHg and standard deviation less than 8 mmHg during T2 and T4, respectively. CONCLUSION: The study indicates SMA might be an alternative site for invasive BP monitoring during abdominal aorta occlusion and release, especially in cerebrovascular-related research.

Novel coronavirus pneumonia disease (COVID-19) caused by SARS-CoV-2 began to emerge in Wuhan, Hubei, China in December 2019. It is currently spreading globally including Japan. The COVID-19 case in Japan began to appear in middle January 2020 and continued to increase over time. The period from middle January to the end of February is considered to be the initial stage of domestic transmission in Japan. This article described the spread of 935 COVID-19 cases related to Japan by the end of February 2020, including the 15 infected Japanese returned from Wuhan, the 696 infected individuals in the large-scale cruise ship 'Diamond Princess' and the 224 infected individuals in Japan. This paper summarizes the measures to control the spread of SARS-CoV-2 in Japan, such as limiting RT-PCR detection for SARS-CoV-2, reducing the number of patients with mild illness who go to medical institutions unnecessarily, formulating guidelines for SARS-CoV-2 infection consultation, canceling large gatherings and temporarily closing schools. This paper further points out the problems encountered in the prevention and control of the spread of SARS-CoV-2 in Japan, such as the slow detection of RT-PCR, the risk of infection faced by medical staff, the regional differences in the domestic health care service system, the confusion of information disclosure and management. The above introduction as allows us to acquire a better understanding of the new coronavirus pneumonia in Japan and the world and may provide reference for the control the epidemic of COVID-19 in worldwide.

OBJECTIVE: To investigate the influence of posterior osteotomy on spinopelvic parameters in lumbar degenerative kyphosis (LDK) patients. METHODS: The clinical data of 21 patients with lumbar degenerative kyphosis who underwent osteotomy from January 2012 to December 2015 were retrospectively analyzed. There were 5 males and 16 females, aged from 55 to 76 years with an average of (66.24±5.13) years. All patients had taken preoperative and postoperative full length spinal X-ray, analyzing the spinopelvic parameters as thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS). RESULTS: All operations were successful, the average operative time was 190 min (160 to 220 min) and intraoperative blood loss was 1 000 ml (800 to 1900 ml). Parameters of the patients between preoperative and period 1-year follow-up were as follows : preoperative TK increased from (31.67±21.13) ° to (34.67±11.60) °, LL corrected from (4.76±3.17) ° to (37.41±6.28) °, PT reduced from (33.94±5.01) ° to (20.12±5.36) °, and SS improved from (18.47±2.60) ° to (31.71±4.30) °, SVA restored from (13.24±3.60) cm to (2.82±1.33) cm. There were significant differences of spinopelvic parameters between preoperation and postoperation (<0.05). CONCLUSION Posterior osteotomy can effectively reconstruct the sagittal balance of spinopelvis in patients with lumbar degenerative kyphosis. The recovery of lumbar lordosis and sacral slope is closely related to the reconstruction of sagittal balance.

Malignant pleural effusion (MPE) is one of the common complications of tumor. Acupuncture-moxibustion therapy has several advantages for treatment of MPE. Acupuncture is regarded as a complex individualized intervention, and its characteristics of TCM is difficult to be reflected by strict randomized controlled trials. The registry study provides more possibilities for the data collection of individualized diagnosis and treatment under the guidance of the overall concept and syndrome differentiation, and is more suitable for data management and collection of large samples and multi-center trials in the real-world study. It has become an opportunity to carry out real-world study of acupuncture for MPE. There are many challenges in the registry study of acupuncture for MPE. However, it is of great significance to collect real-world data of acupuncture for MPE to improve the clinical effect of MPE and provide a new clinical research method for acupuncture in tumors and related complications.

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ²=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ²=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ²=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ²=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Objective To use the "three-dimensional quality structure" model as a theoretical basis, based on multiple evidence-based evidence, to construct ICU nursing sensitivity quality indicators, and to provide reference for the evaluation and monitoring of ICU department nursing safety quality. Methods Evidence-based and Delphi methods were used to complete 3 rounds of inquiry among 27 experts to obtain consensus opinions of experts and to determine nursing quality indicators. Results Of the 30 articles included, 17 wereⅢA, 10 wereⅣA, 2 wereⅤA, and 1 wasⅤB. According to the"three-dimensional structure theory"model, the included indicators were sorted out and a total of 12 items were obtained. The effective recovery rate of 3 rounds of questionnaires was 96.6％, 100.0％, and 96.4％. The authoritative coefficients were 0.899, 0.895, and 0.909, and the coordination coefficients of the first, second, and third indexes were 0.340, 0.379, and 0.403, respectively,with significance (P<0.01). The final ICU nursing sensitivity quality indicator consists of 3 first-level indicators, 15 second-level indicators and 69 third-level indicators. The selection of indicators at all levels gradually converges. Conclusions The established ICU nursing sensitivity quality index accords with the principle of scientificity and practicality, and can be used for ICU department nursing quality assessment.

Objective To investigate the significance of superb microvascular imaging (SMI) for the detection of neovascularization in carotid atherosclerotic plaques.Methods SMI detected 28 carotid atherosclerotic plaques in 28 patients who underwent carotid endarterectomy.The SMI grade of carotid plaque neovascularization was assigned based on the following grading system:Grade 0,no neovascularization;grade 1,some neovascularization;grade 2,neovascularization observed in the shoulder of the plaque;and grade 3,widely distributed new blood vessels.SMI was used to evaluate the degree of blood flow,maximum flow velocity,and resistance index of the new vessels in the plaque.Microvascular density was measured with CD31 staining.Results Clear correlations were observed between neovascularization density on histopathological staining of the plaque and the degree of blood flow detected with SMI (rs=0.788,P ＜ 0.001).The classification of neovascular blood flow in the plaque was positively correlated with plaque thickness (rs=0.686,P=0.002).Of the 28 cases,neovascularization was detected in 23;of these 23 cases,the direction of blood flow was from the adventitia to the intima in 17 (75％) cases,while 6 (25％) cases showed an irregular direction of blood flow.The mean neovascular flow velocity was (5.620±0.131) cm/s,and the mean neovascular resistance index was 0.660 ± 0.090.Conclusion SMI is useful for the evaluation of carotid atherosclerotic plaque neovascularization.
