Paratesticular liposarcoma: the clinicopathological features of nineteen cases / 中华病理学杂志

Objective: To investigate the clinicopathological features and differential diagnoses of paratesticular liposarcoma. Methods: The cases were collected from 2012-2020, from the archives of the Department of Pathology, Peking University Third Hospital, with diagnosis confirmed by histology, immunostaining and FISH tests. Results: Totally 19 patients were enrolled (including 11 in-hospital patients and 8 consultant cases). The patients aged 37-84 years (mean 57 years). The preoperative clinical diagnoses were spermatic cord/inguinal masses (nine patients), scrotal masses (seven patients), and inguinal hernia (three patients). Six lesions recurred after local resection, including one case extending from pelvic liposarcoma. Histologically, there were 10 cases of well-differentiated liposarcoma (WDLPS) and nine cases of dedifferentiated liposarcoma (DDLPS). WDLPSs mostly showed the combined features of lipoma-like, inflammatory and sclerosing subtypes (six patients); the other four WDLPSs had pure lipoma-like subtype features. DDLPSs were low-grade (three patients) or high-grade (six patients), with the morphology resembling myxofibrosarcoma, inflammatory myofibroblastoma, spindle cell sarcoma, pleomorphic undifferentiated sarcoma and pleomorphic liposarcoma. Intense inflammatory cells infiltration was commonly observed in five WDLPSs and two DDLPSs. Ossification was observed in three tumors. Immunohistochemically, the tumors were positive for MDM2 (8/10) and CDK4 (10/10), which were expressed in lipo-differentiating cells, spindle cells in WDLPS, and in dediffferentiated components. S-100 was only expressed by lipocytes (10/10). CD34 expression was positive and diffuse in the stromal cells of WDLPSs and focal or diffuse in dedifferentiated areas (10/10). FISH tests with an MDM2 gene probe were positive (12/12). Conclusions: Paratesticular liposarcoma may be overlooked by both clinicians and pathologists. WDLPS and DDLPS predominate, showing various histologic divergences. The presence of amplification of the 12q14-q15 region (containing the MDM2 and CDK4 genes) is helpful for making the correct diagnosis.

Ameliorative Effect of miR-31 on Liver Injury in Type 2 Diabetic Mice / 中国生物化学与分子生物学报

Type 2 diabetes mellitus (T2DM) is a metabolic disease with an increasing incidence worldwide, which leads to damage to various tissues and organs including the liver. MiR-31 is conserved across species and closely associated with metabolic diseases, but its role in type 2 diabetic liver injury has not been elucidated. This study aimed to investigate the effect of miR-31 on liver injury in type 2 diabetes and its underlying mechanism. Four to six weeks old male FVB mice and miR-31-positive transgenic mice were randomly divided into FVB mice control group (C), FVB mice induced diabetes group (DM) and miR-31-overexpression transgenic mice induced diabetes group (31DM). After 1 week of adaptive feeding, the T2DM mouse model was induced by high-fat feeding combined with intraperitoneal injection of streptozotocin (STZ) for 6 weeks. The general condition of mice and related metabolic indicators showed that the increased food and water intake, weight loss and glucose and lipid metabolism disorders could be reversed by miR-31 in T2DM mice. HE staining and liver histological activity index (HAI) scoring results showed that miR-31 improved the inflammatory status in the liver tissue of T2DM mice and decreased the HAI score. RT-qPCR results showed that the high expression of miR-31 was accompanied by a decrease in the expression of activating transcription factor 6 (ATF6) mRNA in the liver of T2DM mice. Furthermore, Western blotting results showed that miR-31 inhibited the expression of endoplasmic reticulum stress-related proteins such as ATF6, glucoregulatory protein 78 (GRP78) and C/EBP homologous protein (CHOP) in the liver of T2DM mice. In conclusion, miR-31 may ameliorate liver injury in T2DM mice by regulating glucose and lipid metabolism disorders and insulin resistance, and inhibiting endoplasmic reticulum stress factors such as ATF6, GRP78, and CHOP.

OBJECTIVES@#To investigate the epidemiological characteristics of antisocial personality disorder (ASPD) in young men in Chengdu and explore the characteristics and risks of violence.@*METHODS@#Stratified random sampling was used to conduct a self-assessment questionnaire survey in 4 108 males aged from 18 to 34 in Chengdu, including general demographic characteristics, structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders (SCID-Ⅱ) personality disorder screen questionnaire, violence questionnaire, psychosis screening questionnaire (PSQ), Alcohol Use Disorders Identification Test (AUDIT) and drug use. χ2 test, univariate and multivariate logistic regression were used for analysis and odds ratio (OR) was calculated.@*RESULTS@#The positive rate of ASPD was 5.91%, which was associated with young age, unmarried, unemployment state, low educational level, violent behavior, psychotic symptoms, alcohol and drug use (P<0.05). Young men with ASPD also had a risk (P<0.05) of violence (OR was 8.51), multiple violence (OR was 16.57), injury (OR was 6.68), intentional violence (OR was 11.41), etc., the risk decreased after controlling for psychotic symptoms and substance abuse, but was still statistically significant.@*CONCLUSIONS@#The risk of violence, severe violence and intentional violence in young men in Chengdu is high, and psychotic symptoms and substance abuse increase the risk of ASPD violence and relate characteristics.

Design of dual targeting immunomicelles loaded with bufalin and study of their anti-tumor effect on liver cancer / 中西医结合学报

OBJECTIVE@#Bufalin is an effective drug for the treatment of liver cancer. But its high toxicity, poor water-solubility, fast metabolism and short elimination half-life limit its use in tumor treatment. How to make the drug accumulate in the tumor and reduce side effects while maintaining its efficacy are urgent problems to be solved. The goal of this study is to solve these problems.@*METHODS@#A copolymer with tunable poly-N-isopropylacrylamide and polylactic acid was designed and synthesized. The corresponding dual targeting immunomicelles (DTIs) loaded with bufalin (DTIs-BF) were synthesized by copolymer self-assembly in an aqueous solution. The size and structure of DTIs-BF were determined by ZetaSizer Nano-ZS and transmission electron microscopy. Then, its temperature sensitivity, serum stability, critical micelle concentration (CMC), entrapment efficiency (EE), drug release and non-cytotoxicity of blank block copolymer micelles (BCMs) were evaluated. Next, the effects of DTIs-BF on cellular uptake, cytotoxicity, and tumor cell inhibition were evaluated. Finally, the accumulation of DTIs-fluorescein isothiocyanate (FITC) and the in vivo anti-tumor effect were observed using an interactive video information system.@*RESULTS@#DTIs-BF had a small size, spherical shape, good temperature sensitivity, high serum stability, low CMC, high EE, and slow drug release. The blank BCMs had very low cytotoxicity. Compared with free bufalin, the in vitro cellular internalization and cytotoxicity of DTIs-BF against SMMC-7721 cells were significantly enhanced, and the effects were obviously better at 40 °C than 37 °C. In addition, the therapeutic effect on SMMC-7721 cells was further enhanced by the programmed cell death specifically caused by bufalin. When DTIs-FITC were injected intravenously in BALB/c nude mice bearing liver cancer, the accumulation of FITC was significantly increased in tumors.@*CONCLUSION@#DTIs-BF is a potentially effective nano-formulation and has broad prospects in the clinical treatment of liver cancer.

Objective: To investigate the efficacy and safety of left bundle branch area pacing (LBBaP) with the new simplified approach (nine-partition method). Methods: A total of 118 patients with clinical indications and received pacemaker implantation from December 1, 2018 to December 31, 2019 in Beijing Anzhen Hospital were enrolled. LBBaP was performed with the nine-partition method (in the right anterior oblique 30° position, the ventriculogram was divided into nine partitions and the initial implant sites were located in the lower base 1/3 partitions). In X-ray image, the 3830 lead is located in the left bundle branch area, the unipolar pacing QRS wave is in the form of right bundle branch block, and the peak time from stimulation to left ventricular activation<90 ms is defined as successful operation. The clinical characters, such as the methods of venipuncture, electrode parameters, operation duration, fluoroscopy duration, the peak time from stimulation to left ventricular, pacemaker types, surgical success rate, complications, and immediate postoperative ECG parameters were collected. The patients were followed up after the operation, and the electrode parameters and postoperative complications were recorded. Results: This study is a retrospective study. There were 62 (52.5%) male patients in this cohort, the average age was (65.9±13.4) years old,and there were 49(41.5%) sick sinus syndrome, 6(5.1%) abnormal sinus node and atrioventricular node simultaneously, 63(53.4%) atrioventricular block, 26(22.0%) atrial fibrillation, 20(16.9%) cardiomyopathy; the baseline duration of QRS was (109.21±39.03) ms. Successful LBBaP was achieved in 109 patients with"nine-partition method"and the success rate was 92.4%; 104 patients (95.5%) were axillary vein puncture, 5 (4.6%) were subclavian vein puncture; the operation duration was (80.3±23.0) min, the fluoroscopy duration was (12.29±5.13) min; the QRS duration after LBBaP was (116.36±18.11) ms. The threshold of the left bundle branch (LBB) lead was (0.92±0.63) V, the R wave amplitude was (10.60±5.04) mV and the impedance was (798.71±194.90) Ω. In 1 V pacing, the peak time from stimulation to left ventricular activation was (67.91±12.15) ms, and in 5 V pacing was (67.52±12.45) ms; 1 case (0.9%) with a single-chamber pacemaker implanted, 106 cases (97.3%) with dual-chamber pacemaker and 2 cases (1.8%) with three-chamber pacemakers. There were no hematomas, pneumothorax, hemothorax, electrode dislocation, infection, and capsular hemorrhage and other serious surgery-related complications during the operation. A total of 97 patients (89.0%) were followed up for (6.21±2.90) months. The electrode parameters of all patients were stable and no complications observed. Conclusions: The LBBaP with nine-partition method is a simple, safe and effective physiological pacing approach. However, its long-term effect still needs to be further verified.

Advances in the prediction and treatment of recurrent pancreatic cancer / 医学研究生学报

Patients with pancreatic adenocarcinoma who underwent surgical resection have poor prognosis, with the recurrence rate of over 80% within two years. Currently, the treatment of recurrent pancreatic cancer is still in the exploratory phase, and the efficacy is only limited to chemotherapy. In addition, there are differences in the efficacy of different chemotherapy schemes, and there is no unified chemotherapy scheme. Meanwhile, new radiotherapy and surgical treatment have been proposed for the treatment of recurrent pancreatic cancer, but its efficacy is yet to be confirmed. This paper summarizes the factors to predict postoperative recurrence, various chemotherapy schemes and new radiotherapy methods, reviews and analyzes the effectiveness of surgical treatment on recurrent pancreatic cancer.

Intra-nucleus accumbens shell injection of baclofen blocks the reconsolidation of conditioned place preference in morphine-addicted mice / 生理学报

Preclinical studies suggest that the GABA receptor is a potential target for treatment of substance use disorders. Baclofen (BLF), a prototypical GABA receptor agonist, is the only specific GABA receptor agonist available for application in clinical addiction treatment. The nucleus accumbens shell (AcbSh) is a key node in the circuit that controls reward-directed behavior. However, the relationship between GABA receptors in the AcbSh and memory reconsolidation was unclear. The aim of this study was to investigate the effect of intra-AcbSh injection of BLF on the reconsolidation of morphine reward memory. Male C57BL/6J mice were used to establish morphine conditioned place preference (CPP) model and carry out morphine reward memory retrieval and activation experiment. The effects of intra-AcbSh injection of BLF on morphine-induced CPP, reinstatement of CPP and locomotor activity were observed after environmental cues activating morphine reward memory. The results showed that intra-AcbSh injection of BLF (0.06 nmol/0.2 μL/side or 0.12 nmol/0.2 μL/side), rather than vehicle or BLF (0.01 nmol/0.2 μL/side), following morphine reward memory retrieval abolished morphine-induced CPP by disrupting its reconsolidation in mice. Moreover, this effect persisted for more than 14 days, which was not reversed by a morphine priming injection. Furthermore, intra-AcbSh injection of BLF without morphine reward memory retrieval had no effect on morphine-associated reward memory. Interestingly, administration of BLF into the AcbSh had no effect on the locomotor activity of mice during testing phase. Based on these results, we concluded that intra-AcbSh injection of BLF following morphine reward memory could erase morphine-induced CPP by disrupting its reconsolidation. Activating GABA receptor in AcbSh during drug memory reconsolidation may be a potential approach to prevent drug relapse.

Influence of pulmonary hypertension on patients with advanced chronic obstrnctive pulmonary disease prior to lung transplantation / 中华器官移植杂志

Objective To study the influence of pulmonary artery hypertension (PAH) on survival of patients with advanced chronic obstructive pulmonary disease (COPD) on the waiting list of lung transplantation.Methods The characteristics of 143 patients with COPD receiving lung transplantation evaluation from January 2014 to August 2016 were queried.Mild PAH was defined as mean pulmonary artery pressure (mPAP) ≥25 mmHg and severe ≥35 mrnHg by right heart catheterization measurements.The incidence of PAH was studied,and the patients were divided to different groups to determine the effect of PAH on survival prior to transplantation on the basis of different definitions of PAH.Kaplan Meier method was used to draw survival curves,and a log-rank test was used to analyze the effect of PAH on survival of COPD patients on the waiting list of pulmonary transplantation.Univariate and multivariate Cox proportional hazard models were performed to test the relationship between each main covariate and the hazard of mortality.The waiting time was tracked from wait list entry date until death or censoring,and the censoring issues were as follows:receiving lung transplantation,removing from the waiting list without transplant,and still wating for donor until the last follow-up day (2016-08-30).Results Of 143 COPD patients,there were 119 males and 24 males,with mean age of 61.73 years old;46 patients received lung transplantation,and the remaining 97 not;50 had mPAP ≥25 mmHg and 21 had mPAP ≥35 mmHg.A total of 23 cases (22.88％) died on the waiting list.Thirty-eight patients were removed from the list prior to transplantation,and 36 were still on the waiting list.Kaplan-Meier survival function showed suvival of patients with mild PAH or severe PAH was significantly shorter than that of patients without PAH (P＜0.001).Using Cox proportional hazards models,univariate analysis revealed significant differences in survival for mild PAH (HR =2.147,95％CI 1.429-3.157,P＜ 0.001) and severe PAH (HR =3.458,95 ％ CI 2.518-4.859,P＜0.001).Multivariate Cox models identified significant risk for death for mild PAH (HR=2.518,95％CI 1.728-3.364,P＜0.001) and severePAH HR=4.027,95％ CI 3.257-4.703,P＜0.001).Conclusion The incidence of PAH among COPD patients waiting for lung transplantation was high.PAH is associated with significantly increased risk of death among COPD patients waiting for lung transplantation.

Short-term efficacy and safety of low-intensity extracorporeal shock wave therapy in erectile dysfunction: a systematic review and meta-analysis

ABSTRACT Aim: The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. Materials and Methods: Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1XSmonth after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. Results: Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95°/o confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n= 101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n= 121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. Conclusion: LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and longterm follow-up time studies are needed to confirm our analysis.

Objective To compare the effects of moxibustion at different temperatures on blood lipid and TRPV1 in dorsal root ganglion with hyperlipidemia rats; To verify the correlation between efficacy of adjusting fat of moxibustion with activating of TRPV1. Methods The rat model of hyperlipidemia was made by high fat diet. 60 SD mice were randomly divided into four groups: control group, model control group, the 38 ℃ moxibustion group and the 45 ℃ moxibustion group, with 15 mice in each group. Acupoints Shenque and Zusanli were chosen under moxibustion for 10 minutes each time, once another day, for 4 weeks, in the 38 ℃ moxibustion group and the 45 ℃moxibustion group. Blood was taken after intervention, and blood TC, TG, LDL-C and HDL-C of the mice were detected by oxidase method; the dorsal root ganglion was taken to detect the expression of TRPV1 mRNA by real-time fluorescence quantitative PCR. Results Compared with model group, blood lipid indexes in moxibustion groups had different changes, with statistical significance compared with 45 ℃ moxibustion group (P<0.05, P<0.01), and there was statistical significance between 38 ℃ moxibustion group and 45 ℃ moxibustion group (P<0.01); there was statistical significance in TRPV1 mRNA of dorsal root ganglion among 45 ℃ moxibustion group and other three groups (P<0.01). Conclusion The correlation between efficacy of adjusting fat of moxibustion with activating of TRPV1 has been confirmed.
