【Objective】 To analyze the efficacy and safety of intralesional triamcinolone acetonide in the treatment of mass granulomatous mastitis (GLM). 【Methods】 Retrospective analysis was made on 67 patients with GLM who were treated in Xijing Hospital from July 2021 to May 2022 and met the inclusion criteria. Among them, 31 patients were treated with local injection of triamcinolone acetonide, while 36 ones were treated with oral methylprednisolone. All the included patients underwent surgical treatment after their condition met the surgical criteria, and the follow-up period lasted for up to six months after surgery. The two groups were compared in improvement of symptoms and signs, treatment time, clinical effectiveness and safety, and recurrence rate. 【Results】 The effective rate of triamcinolone acetonide group and methylprednisolone group was 100%, but the clinical cure rate was significantly higher in triamcinolone acetonide group than in methylprednisolone group in stratified analysis (P<0.05). The improvement time of symptoms and signs in triamcinolone acetonide group was significantly shorter than that in methylprednisolone group (P<0.05). The incidence of side effects in triamcinolone acetonide group was also significantly reduced compared to methylprednisolone group (P<0.05). Follow-up for half a year showed no recurrence in both groups. 【Conclusion】 Compared with the traditional oral methylprednisolone group, local injection of triamcinolone acetonide in the treatment of mass granulomatous mastitis can rapidly relieve clinical symptoms and signs, shorten treatment time, and has higher efficiency and fewer side effects. Local injection of hormone combined with surgery is effective in treating mass granulomatous mastitis with low recurrence rate.

The value of red blood cell distribution width to platelet ratio and C-reactive protein to albumin ratio combined with BISAP scores in the assessment of acute pancreatitis / 中华急诊医学杂志

Objective:To explore the value of red blood cell distribution width to platelet ratio (RPR), C-reactive protein to albumin ratio (CAR) combined with bedside index for severity in acute pancreatitis (BISAP) score in assessing the severity of acute pancreatitis (AP).Methods:The AP patients in the First Affiliated Hospital of Jinzhou Medical University from January to December 2020 were respectively collected. According to the severity of the disease, the patients were divided into the mild acute pancreatitis (MAP) group, moderate severe acute pancreatitis (MSAP) group, and severe acute pancreatitis (SAP) group. The general information and laboratory indicators of the patients were collected and scored according to the BISAP scoring standard. Spearman correlation analysis was used to explore the correlation of RPR, CAR and BISAP score in three groups of patients and their correlation with AP severity. Model 1 [MAP group and non-MAP group (MSAP group + SAP group)] and model 2 [non-SAP group (MAP group + MSAP group) and SAP group] were constructed. Multivariate binary logistic regression was used to analyze the independent factors of the non-MAP group and SAP group. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) to analyze the value of RPR, CAR, and BISAP score alone and in combination to judge the severity of AP patients.Results:A total of 197 AP patients who met the criteria were included, including 102 MAP patients, 56 MSAP patients, and 39 SAP patients. There were significant differences in RPR, CAR and BISAP score among patients with different AP severity ( P<0.001). RPR, CAR and BISAP score were positively correlated, and all three were positively correlated with AP severity ( r=0.435, 0.490, 0.628, P<0.001). RPR and CAR were independent factors for the severity of AP, and the combination of RPR, CAR and BISAP score was better than a single indicator in judging the severity of AP patients. The AUC of the three combined in Model 1 and Model 2 were 0.868 and 0.889, respectively. Conclusions:RPR, CAR combined with BISAP score has a good application value in the evaluation of AP, and is suitable for clinical promotion.

Feasibility and efficacy of percutaneous pulmonary vein stenting for the treatment of patients with severe pulmonary vein stenosis due to fibrosing mediastinitis / 中华心血管病杂志

Objective@#To evaluate the feasibility and safety percutaneous pulmonary vein intervention in patients with severe pulmonary vein stenosis (PVS) caused by fibrosing mediastinitis(FM).@*Methods@#This retrospective analysis included 5 FM patients (2 male, 3 female, 54-77 years old) confirmed by clinical presentation and chest computed tomography (CT) scan from January to June 2018 who were from Gansu Provincial Hospital and Shanghai Chest Hospital. CT pulmonary angiography (CTPA) further revealed severe PVS caused by fibrotic tissue compression in mediastinum. After selective pulmonary vein angiography, gradually balloon angioplasty was used to expand the pulmonary vein and then stents were implanted in the pre-dilated stenotic pulmonary veins. Evaluation of therapeutic effect was made at 6 months after the procedure.@*Results@#All of 11 serious compression PVS were treated with stent implantation (diameter: 7-10 mm, length: 17-27 mm). After stenting, degree of pulmonary vein stenosis decreased from (83±16)% to (12±4)% (P<0.01). The minimal diameter of the stenotic pulmonary vein was significantly increased from (0.8±0.5)mm to (7.5±0.8)mm (P<0.01). Trans-stenotic gradient decreased from (27.0±15.1)mmHg (1 mmHg=0.133 kPa) to (2.50±0.58)mmHg (P<0.05). Mean pulmonary pressure measured by cardiac catheter decreased from (45.0±9.0)mmHg to (38.7±8.4)mmHg (P<0.05). One patient experienced cardiac arrest due to vagal nerve reflex during big sizing balloon stent dilation and recovered after cardiopulmonary resuscitation. There were no other serious procedure related complications. During the follow-up, severe stenosis at end of proximal stent was evidenced in 1 patient due to fibrotic compression, and another patient developed in-stent thrombosis due to discontinuation of prescribed anticoagulant.@*Conclusion@#Percutaneous intervention for severe pulmonary vein stenosis caused by FM is feasible and safe, and can improve hemodynamic caused by the compression of mediastinal vascular structures in these carefully selected patients.

Correlation between muscle mass reduction and quality of life in elderly lung cancer patients / 中华老年医学杂志

Objective To investigate the relationship between muscle mass reduction and quality of life in elderly lung cancer patients at the initial visit.Methods Totally 221 patients with non-small cell lung cancer undergoing chest and abdominal CT examination were included in this study at Fenyang Hospital in Shanxi Province.The Pearson's correlations of skeletal muscle index(SMI) and skeletal muscle radiodensity(SMD)with the disease stage,physical function,role of physical function,global quality of life,fatigue and dyspnea were analyzed.Results The average age of 221 patients was(70.2t9.0)years.The mean SMI for men and women was(46.7± 7.8)cm2/m2 and(39.4 ±6.4) cm2/m2 respectively.Multivariate linear regression analysis showed that SMI affected the body function,role of physical function,global quality of life,and fatigue dimension(all P ＜ 0.05),and SMD affected the physical function of life quality and dyspnea dimension(P ＜0.05).SMI was related to the physical function and role of physical function(men:r =0.287 and 0.245,P =0.001 and 0.006;women:r=0.296 and 0.395,P =0.004 and 0.000).In male patients,SMO was also associated with low global quality of life and fatigue(r=0.191 and-0.198,P =0.032 and 0.026).The above relationships did not change even after adjusting for the effect of age and disease stages.Low SMD was associated with low physical function and dyspnea in both men and women(men:r =0.287 and 0.245,P=0.037 and 0.049;women.:r=0.281 and-0.262,P=0.006 and 0.010),and SMD was associated with dyspnea only in women even after adjusting for age and disease stages.A correlation between SMI and the disease stage was found in both men and women(male:r =-0.266,P=0.003;female:r=-0.223,P=0.005).Conclusions Changes in muscle mass may affect the physical function,role of physical function and global quality of life in elderly patients with non-small cell lung cancer.

A study on the timing of liver transplantation and factors influencing prognosis in patients of acute liver failure / 中华普通外科杂志

Objective To explore the optimal timing of liver transplantation for acute liver failure,and analyze relative risk factors affecting patients' prognosis.Methods We retrospectively analyze perioperative clinical data of 50 patients suffering from acute liver failure who underwent liver transplantation between March 2005 and June 2010 in Organ Transplantation Center,the First Affiliated Hospital of Sun Yat-sen University.Patients were divided into survival group and death group.Clinical data before operation were collected and analyzed by univariate and multivariate analysis,respectively.Risk factors influencing the perioperative mortality were selected and were used to direct the operation time.Results There were 50 patients who underwent liver transplantation and 11 cases died during perioperative phase.Five patients died of respiratory infection,three of acute renal failure,one of digestive tract hemorrhage,one of primary allograft failure and one of multiple organ failure.The perioperative,one-year and three-year survival rate were 78％,74％ and 72％ respectively.In the univariate analysis,age,bilirubin level,prothrombin time,creatinine level,grade of encephalopathy and MELD score were found to be significantly different between survival group and death group.The multivariate analysis revealed that age≥65 y,INR ≥3.5,creatinine level ≥ 2.5 mg/dl and MELD score ≥ 40 were independent risk factors affecting survival.Conclusions Liver transplantation is an effective treatment of choice for acute liver failure.Appropriate timing of transplantation helps achieve a high survival rate.

Over-expressed MiR-103 promotes porcine adipocyte differentiation / 生物工程学报

To clarify the function of miR-103 in the differentiation of porcine preadipocyte, we carried out real-time PCR to detect the expression pattern of miR-103 during adipogenesis, and clarified its expression tendency through cell differentiation. Then we used adenovirus that overexpressed miR-103 to infect porcine preadipocyte. Subsequently, mRNA and protein expression of adipogenesis marker--PPARgamma and aP2 was analyzed by real-time PCR and Western blotting. At last, Oil-Red O staining was used to detect lipids accumulation in the 8th day after adipogenic inducement. The expression of miR-103 increased during adipocyte differentiation; compared with the control, the preadipocyte infected by pAd-miR-103 had an elevated expression level of adipocyte marker gene PPARgamma, aP2, and obvious lipid droplet was seen in the 8th day after adipogenic inducement. These results showed that miR-103 can enhance adipogenesis in primary cultured porcine adipocytes.
