Purpose To describe the clinical and pathological features of atypical vascular lesions (AVLs) after conservative surgery and radiation of the breast cancer,and to discuss the association with post-radiation angiosarcoma.Methods The clinical and pathological features in one case of AVLs was evaluated.The literatures were reviewed.Results The patient is a 57-yeAR~-old female who underwent a conservative surgery of the right breast because of a carcinoma.She received standard dose of radiation as adjuvant therapy.Three years later, multiple erythematous plaques developed around the former scar, which radiated to the nipple.Clinically,the plaques were considered as relapses of the carcinoma.However, fine needle aspiration gave negative results.Biopsy of one large plague revealed a circumscribed vascular lesion confined to the superficial dermis.It was composed of thin-walled anastomosing lymphatic vessels lined by attenuated endothelial cells.In focal areas, the vessels extended to the mid-dermis.Immunohistochemically, the endothelial cells were positive for CD31, CD34 and D2-40,with absent of α-SMA positive pericytes.Review of the breast tumor sections showed an invasive micropapillary carcinoma.Conclusions AVLs is a rare vascular lesion related with conservative surgery and post-radiation therapy of the breast.AVLs may represent as a precursor of breast angiosarcoma.Being familiar with the clinicopathologic characteristics of AVLs is important not only for the pathologists but also for the clinicians.

Visfatin was expressed in rat anti mouse islets,as well as in MIN6 cells. The visfatin expression was affected by various concentrations of environmental glucose (5.5 and 33.3 mmoL/L) and palmitate(0.5 mmol/L). As compared with low-level glucose medium (5.5 mmol/L, 1.0±0.11) , visfatin expression increased in media with high glucose and palmitate (1.32 ±0. 18, 1. 33±0. 15,1.72±0.27, all P<0. 05). The result suggests that visfatin seems to be involved in the regulation of insulin secretion.

Objective:To compare the safety and efficacy of continuous transversus abdominis plane (CTAP) block and patient-controlled intravenous analgesia (PCIA) in abdominal surgery postoperatively.Methods:PubMed, Embase, Web of Science, CNKI and other English and Chinese databases were searched since their establishment to February 2021 with "continuous/modified, transversus/transverse abdominis plane block, TAP block, patient controlled analgesia, patient-controlled analgesia, patient controlled intravenous analgesia, patient-controlled intravenous analgesia, PCA/PCIA/IV-PCA" as the search keywords. According to the analgesia treatment methods, patients were divided into continuous transversus abdominis plane block group (CTAP group) and patient-controlled intravenous analgesia group (PCIA group). Review Manager 5.4 software was used to conduct a Meta-analysis on outcome indicators such as postoperative nausea and (or) vomiting (PONV), dizziness, pain score and recovery status after abdominal surgery. Risk ratio ( RR) was calculated for counting data, Mean ± SD was calculated for measurement data. Heterogeneity was measured by I2, and related data were analyzed by using either a fixed effects model or a random effects model. Results:(1) The results of literature search: A total of 6 randomized controlled trials, including 2 published in English and 4 published in Chinese were analyzed, involving 479 patients. The results of the Meta-analysis: Compared with PCIA, CTAP block had lower incidence of PONV ( RR=0.22, 95% CI: 0.08-0.62, P<0.01), lower incidence of dizziness ( RR=0.27, 95% CI: 0.09-0.79, P=0.02), lower pain scores on movement at 24 h ( MD=-0.75, 95% CI: -1.42--0.08, P=0.03) and 48 h ( MD=-0.68, 95% CI: -1.05--0.31, P<0.001) postoperatively, and earlier time of first mobilization ( MD=-0.49, 95% CI: -0.69--0.30, P<0.001) and first exhaust ( MD=-10.47, 95% CI: -13.53--7.41, P<0.001), with statistically significant differences. However, there were no statistically significant differences in pain scores at rest at 24 h ( MD=-0.25, 95% CI: -0.57-0.08, P=0.14) and 48 h ( MD=-0.15, 95% CI: -0.39-0.09, P=0.22) postoperatively and postoperative length of hospital stay ( MD=-1.01, 95% CI: -2.28-0.26, P=0.12). Conclusion:CTAP block is a relatively safe and effective analgesic method, and it′s more consistent with the concept of enhanced recovery after surgery (ERAS) and can be recommended as an alternative method of PCIA.

Objectives To investigate the characteristics of changes in serum metabolic profile before and after resection of carcinoma tissues to establish a disease distinguishing model,to analyze the changing trend of characteristic metabolites,and to determine the molecular mechanism and potential clinical value of characteristic metabolic markers for HBV-related liver cancer.Methods Ultraperformance liquid chromatography-mass spectrometry (UPLC-MS) was used to analyze the serum metabolites of 15 patients with hepatocellular carcinoma (HCC) before and after partial hepatectomy and on 25 healthy volunteers.The pattern recognition method and nonparametric test analyzes were used to analyze the data and to identify the specific metabolites and their changes after resection of carcinoma tissues.Results We established the principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) disease distinguishing model for HCC patients before and after operation as against the healthy volunteers.To distinguish between the liver cancer group and the normal control group,27 characteristic metabolites were selected from the patients before and after resection of carcinoma tissues.Eight moved towards the normal control after resection of carcinoma tissues.This indicated that liver carcinoma was an important impacting factor for these metabolites.Finally,7 metabolites were identified,and these metabolites had high diagnostic value as shown on ROC curves.Conclusions Through serum metabolic profiling of patients before and after resection of carcinoma tissues,a high correlation between metabolism and hepatocellular carcinoma was found.Researches on endogenous metabolites and pathways in liver diseases will provide a better understanding of the molecular mechanisms and provide further directions for clinical diagnosis and treatment.

Objective:To explore the metabolic outcomes of type 2 diabetes patients with different durations after 1 year treatment under the standardized metabolic disease management model.Methods:(1)From September 2017 to September 2018, 345 type 2 diabetes patients in the Standardized Metabolic Management Center(MMC) of Shanghai General Hospital were recruited and included in this research. They were divided into newly-diagnosed type 2 diabetes(duration≤1 year) and long-term groups(duration>1 year). The general characteristics, blood pressures, glycemic levels, lipids levels, control rates and comprehensive compliance rates(blood glucose, pressure and lipids all reached targets) were compared at baseline between 2 groups.(2)All patients underwent one year standardized management, and metabolic indicators mentioned above and control rates at the time were compared as well.Results:(1) At baseline, compared with long-term group, patients in newly-diagnosed type 2 diabetes group were younger ( P<0.01), and 2 h blood glucose level after glucose loading were higher [(15.20±5.26 vs 13.68±4.94) mmol/L, P<0.01]. (2) After one year standardized management, body weight, blood pressure, glucose and lipids metabolism in all patients were significantly improved. Compared with patients in long-term group, newly-diagnosed type 2 diabetes patients achieved better glycemic level [fasting blood glucose(6.27±1.56 vs 7.63±2.08) mmol/L, P<0.01; glycated hemoglobin(6.33±0.96 vs 7.23±1.37) %, P<0.01] , and had higher HOMA-β [(74.01±56.45 vs 40.17±37.07) %, P<0.01]. The glycemic control, blood pressure and blood lipids control rates in both groups increased significantly in one year. Comprehensive compliance rate of the whole patients increased from 5.80% to 24.06%. The metabolism indexes of the newly-diagnosed type 2 diabetes group were better than those of the long-term group[comprehensive compliance rate: (24.73% vs 17.18%, P=0.087, glycemic control rate(84.62% vs 53.37%, P<0.01)]. Conclusion:Standardized metabolic disease management promoted the overall improvement in blood glucose, blood pressure, and lipids levels in type 2 diabetes patients, especially in terms of blood glucose and those of the newly-diagnosed type 2 diabetes. In the future, we should focus on the early diagnosis and treatment of type 2 diabetes, actively promote the MMC model and stress the integrated management of blood glucose, blood pressure, and blood lipid levels. We should pay more attention to the long-term patients, to improve their awareness and treatment compliance.

Objective To explore the association between moxibustion sensation and therapeutic efficacy during moxibustion treatment. Methods By applying Taiyi moxa stick to Shiqizhui (EX-B 8) to treat primary dysmenorrhea, the association between the change of Visual Analogue Scale (VAS) score and the topical moxibustion sensation and transmission types during the 30 min moxibustion treatment was observed. Besides, the occurrence time of transmission, and the transmission distance, width, depth, and direction were recorded. Results Superficial moxibustion sensation occurred in forty patients, of whom, the VAS score changed by (38.50±14.38) mm; heat-penetrating moxibustion sensation occurred in 18 patients, and the VAS score changed by (38.89±12.43) mm; heat-expanding sensation occurred in 6 patients, and the VAS score changed by (45.00±14.10) mm; distant transmission happened in 13 patients, and the VAS score changed by (41.54±13.90) mm. Patients with 4 types of moxibustion sensation had the highest VAS scores both before and after treatment, followed by 3 types, 2 types, and 1 type moxibustion sensation. In comparing the changes of VAS score between 10 min and 20 min treatment and between 20 min and 30 min treatment, the patients with 4 types of moxibustion sensation had the most significant change. Conclusions Different moxibustion sensations occur at different frequencies, and the occurrence of moxibustion sensation is related to the severity of disease condition. The number of moxibustion sensation type can affect the remission process of disease, but can merely influence the treatment result. The single moxibustion sensation (superficial heat only) works faster, usually taking 0~10 min; while the other forms of moxibustion sensation (heat penetrating, heat-expanding, and distant transmission) works slower, usually taking over 20 min.
