Objective To explore the effect of ice pack cold compress on joint pain,swelling and motion after anterior cruciate ligament reconstruction. Methods The data of patients undergoing anterior cruciate ligament reconstruction due to anterior cruciate ligament injury in our hospital from January 2021 to July 2021 were retrospectively analyzed,and 71 patients who received unilateral anterior cruciate ligament reconstruction meeting the standards were divided into two groups according to the odd and even numbers of hospital admission. There were 38 patients in the control group and 33 patients in the experimental group. Thirty-eight patients in the control group did not use ice packs after surgery. Thirty-three patients in experimental group were treated with ice pack after operation. Visual analogue scale was used to evaluate the preoperative and postoperative pain of the control group and experimental group,and the degree of knee swelling and range of motion were measured. Results There was no significant difference in preoperative visual analogue scale between control group and experimental group (P>0.05). The scores of pain in the experimental group were significantly lower than that in the control group at 6,24,48 and 72 hours after surgery,with statistical significance (P<0.001). There was no significant difference in preoperative range of motion between control group and experimental group(P>0.05), the range of motion of the experimental group was significantly better than that of the control group at four different time points of 4,5,6 and 7 days after operation,with statistical significance(P<0.001). There was no significant difference in the degree of preoperative knee joint swelling between the control group and the experimental group(P>0.05),and the degree of knee joint swelling in the experimental group was lower than that in the control group on,1,2 and 3 days after surgery,three different time points, with statistically significant difference(P<0.001). Conclusions Ice pack cold compress can effectively reduce the pain and swelling of the knee joint after anterior cruciate ligament reconstruction and improve the range of motion of the joint.

Objective To evaluate the impact of cardiac rehabilitation on blood lipid level,blood pressure control,exercise endurance,cardiac function, quality of life and lung function in patients with hypertension and atrial fibrillation (AF). Methods This prospective cohort study enrolled 96 patients with AF and hypertension, who were randomly and evenly assigned to the conventional group and the cardiac rehabilitation (CR) group, both treated for at least 6 months. Research indicators included the levels of triglycerides (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C); left atrial diameter (LA), left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDd), anaerobic threshold (AT), peak oxygen uptake volume per kilogram (PeakVO₂/kg), peak ventilation volume (VEpeak), stroke volume (SV), peak oxygen pulse (PeakO₂pluse), changes in blood pressure, 6 minutes walking distance, Borg Fatigue Scale score, Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores. Results At the 6th month of the treatment, the levels of TG, TC, LDL-C, systolic blood pressure (SBP), diastolic blood pressure (DBP) were significantly reduced (P<0.05) in both groups. However, there was no statistical difference among the three blood lipid indicators between the conventional group and the CR group after treatment (P>0.05). Blood pressure dropped significantly(P<0.05) in both groups, especially in the CR group. Meanwhile, after treatment, LA and LVEDd decreased significantly (P<0.05) in both groups, except LVEF. LA decreased significantly (P<0.05) in CR group, compared with conventional group. In addition, AT, PeakVO₂/kg, VEpeak, SV and PeakO₂pluse levels were significantly elevated (P<0.05) in CR group compared with the conventional group after the treatment. There was no significant difference (P>0.05) in the indicators above in the conventional group. Six minutes walking distance were significantly increased (P<0.05) in both groups at 6th month of treatment, compared with the conventional group, the CR group increased more (P<0.05). Borg Fatigue Scale score, SAS score and SDS score were significantly reduced (P<0.05) in CR group at 6th month of treatment, however, there was no statistical difference (P>0.05) in the conventional group compared with that before treatment. The scores above were significantly reduced (P<0.05) in CR group compared with the conventional group after the treatment. Conclusions Cardiac rehabilitation therapy dominated by moderate-intensity exercise intervention can reduce the blood lipid level of atrial fibrillation and hypertension patients, control the blood pressure, improve the left atrial and left ventricular structure reconstruction, increase the exercise endurance, improve cardiopulmonary function, reduce negative emotions and improve the quality of life.

Objective To investigate the value of radial probe endobronchial ultrasound (RP-EBUS)guided multi-dimensional combined examination in the diagnosis of peripheral lung cancer. Methods A retrospective analysis of 74 patients with peripheral lung cancer which were diagnosed in Foshan Second People's Hospital from September 2019 to December 2021 was carried out. RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and DNA methylation detection results were analyzed to obtain the positive diagnosis rate and influencing factors. Results The positive rates of RP-EBUS guided biopsy, brushing biopsy, bronchus alveolar lavage cytology and methylation for peripheral lung cancer were 52.7%, 47.3%, 45.9% and 51.4%, respectively. The positive rate of RP-EBUS guided multi-dimensional combined detection was 71.6%, which was significantly higher than single detection (P<0.05). The positive rate of RP-EBUS multi-dimensional combined examination in lesions diameter ≥30 mm was higher than that of lesion diameter ＜30 mm (82.9% vs 57.6%, P<0.05). The positive rate of RP-EBUS guided multi-dimensional combined group in the upper lobe, middle lobe/lingual lobe, and lower lobe of the lung were 69.7%, 66.7% and 76.9%, respectively, with no significant difference (P>0.05). The positive rate of ultrasound detected lesion in combined group was higher than that of undetected lesions (76.9% vs 33.3%, P<0.05). The ultrasound images of solid center lesions had higher positive rates than that of non solid center lesions (86.0% vs 59.1%, P<0.05). Conclusions RP-EBUS guided multi-dimensional combined examination has a higher positive rate for diagnosis of peripheral lung cancer. The positive rate of diagnosis are related to the size of the lesion, whether the lesion is detected by ultrasound and the characteristics of the ultrasound image of the lesion, but not related to the location of the lesion.

Objective To summarize the diagnostic experiences of blastic plasmacytoid dendritic cell neoplasm (BPDCN) based on the study of its clinicopathological features and immunophenotypes. Methods The clinical data of 2 patients with BPDCN were collected, the structure alteration and cell morphology were observed by HE staining, the immunophenotype of tumor cells were studied by immunohistochemistry staining and flow cytometry was adopted to confirm the bone marrow involvement. Results Two patients, one of whom was a 97 year-old female, presented with cutaneous ecchymosis nodules as the first symptom. The epidermis, but not the dermal, was diffusedly infiltrated by tumor cells, which were medium-sized with irregular nuclei without prominent nucleoli. The other case was a 69 year-old male with lymph node enlargement as the first symptom. The skin was normal, but the lymph nodes were invasively destroyed by tumor cells, which were medium-sized blast-like with prominent nucleoli. The immunophenotypes of the two patients were both positive for CD123, CD4, CD56 and TDT, but negative for B, T lymphocyte derived and myeloid origin markers, both of which involved bone marrow. Conclusions BPDCN is a rare form of hematological neoplasm, skin symptoms or lymph node enlargement may be presented as the initial symptom, the clinical course were highly aggressive with high frequency of bone marrow involvement. The blastic-like lymphoma and leukemia entities should be considered into account for differential diagnose. The precise diagnosis of BPDCN should be established by integrating histomorphology, immunophenotype and clinical presentation information comprehensively.

目的 探讨血沉(ESR)对川崎病(KD)冠状动脉病变(CAL)的预测价值。方法 收集 2017 年 5 月— 2021 年 6 月收治入院的KD患儿的临床资料,分析ESR对KD患儿CAL发生的预测作用。结果 纳入272例KD患儿,70例KD患儿合并CAL,202例KD患儿无CAL。KD患儿的ESR升高。单因素分析提示CAL组的ESR低于非CAL组,差异有统计学意义(P＜0.05)。ROC曲线下的面积为0.586,提示ESR可作为CAL的预测因子(P＜0.05)。ESR预测川崎病冠脉病变发生的临界值为76.5 mm/h。二分类Logistic回归分析显示,ESR是KD患儿发生CAL的独立危险因素(P＜0.05),当ESR＜76.5 mm·h^-1时,KD患儿CAL发生风险增加 (OR=2.38,95% CI: 1.25~4.53)。结论 KD急性期的ESR水平可用于预测KD患儿CAL的发生,ESR＜76.5 mm·h^-1时,提示KD患儿可能会出现CAL。

Objective To investigate the predictive value of erythrocyte sedimentation rate (ESR) on coronary artery lesions (CAL) in Kawasaki disease (KD). Methods Clinical data of children with KD admitted to the hospital from May 2017 to June 2021 were collected to analyze the predictive value of ESR on the occurrence of CAL in children with KD. Results Of the 272 enrolled children with KD, 70 children with CAL and 202 children without CAL. ESR was significantly higher in children with KD. Univariate analysis suggested that ESR was lower in the CAL group than in the non-CAL group, and the difference was statistically significant (P<0.05). The area under the ROC curve was 0.586, suggesting that ESR could be a predictor of CAL (P<0.05). The critical value of ESR for predicting the occurrence of CAL in KD was 76.5 mm/h. Dichotomous Logistic regression analysis showed that ESR was an independent risk factor for the development of CAL in children with KD (P<0.05), and the risk of CAL in children with KD was significantly increased when ESR was<76.5 mm/h. (OR = 2.38, 95% CI: 1.25-4.53). Conclusions ESR levels in the acute phase of KD can be used to predict the development of CAL in children with KD, and ESR <76.5 mm/h suggests that children with KD may develop CAL.

目的 探讨肺部超声(LUS)在高龄(≥75 岁)感染新型冠状病毒肺炎(COVID-19)患者中的应用及后续对病程的监测及诊断价值。方法 回顾性分析2022年11月1日—2023年1月15日本院内科收治的25例COVID-19高龄患者进行病例归纳总结,除临床资料外,动态监测肺部超声检查情况,并与肺CT结果对比,观察检查结果,以及对病程转归的预判及影响。结果 LUS检查提示患者出现不同程度肺间质损伤,包括离散型B线(间质渗出)或融合型B线(渗入肺泡)以及肺实变(肺泡萎陷)。随着病情好转,LUS可见肺实变范围缩小,B线逐步稀疏到消散,A 线出现。结论 LUS与同期胸部CT结果一致性良好。LUS检查安全简便,重复性好,可实时动态监测,即可作为初筛手段,亦可运用于特殊人群,协助临床治疗决策。

Objective To explore the application and follow-up monitoring and diagnostic value of lung ultrasound (LUS) in elderly patients(≥75y) with novel coronavirus pneumonia (COVID-19). Methods Data of 25 COVID-19 elderly patients admitted to the Department of Internal Medicine from November 1, 2022 to January 15, 2023 were retrospectively analyzed and summarized. In addition to clinical data, dynamic monitoring of LUS was performed, and the results were compared with lung CT results. The examination results, as well as the prediction and impact on the course of disease were observed. Results LUS imaging indicated that patients had different degrees of interstitial lung injury, including discrete type B line (interstitial exudation) or fusion type B line (alveolar infiltration) and lung consolidation (alveolar collapse). With the improvement of the disease, the range of lung consolidation seen in LUS was reduced, the B-line was gradually sparse to dissipate, and the A-line appeared. Conclusions The results of LUS and chest CT in the same period are consistent. LUS examination is safe, simple, reproducible, and can be monitored dynamically in real time. It can be used as a primary screening method, and also be used in special patients to assist clinical treatment decision-making.

非酒精性脂肪性肝病(NAFLD)是世界范围内慢性肝病的一个主要原因,约15%的NAFLD患者会发展为非酒精性脂肪性肝炎、肝纤维化、肝硬化甚至肝癌。目前其发病及进展机制尚未明确,也无有效治疗手段。因此,构建临床前NAFLD动物模型至关重要,有助于为NAFLD提供临床治疗的新方案。本文将系统分析目前已构建的NAFLD动物模型在临床前研究中的局限性,并重点总结和综述基于基因编辑在NAFLD动物模型构建中的应用及研究进展,这对于探讨NAFLD发病机制及新药研发具有重要的临床意义。

Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease worldwide, and about 15% of NAFLD patients will develop into nonalcoholic steatohepatitis, hepatic fibrosis, cirrhosis, and ultimately hepatocellular carcinoma. However, the biological mechanism of the pathogenesis and progression of NAFLD is not fully understood, and there are still no effective or targeted therapies for NAFLD. Therefore, it is an urgent need to construct pre-clinical animal models of NAFLD, which will help to better understand and explore the potential therapeutic strategy in the treatment of NAFLD. Here, we summarize the recent advances and limitations of the established animal models of NAFLD and focus on the potential application and research progress of genome editing for constructing the animal models of NAFLD. There animal models will be very useful to reveal the pathologic mechanism of human NAFLD, and to screen new therapeutic drugs.
