Objective To set up the methods of establishing rat primary benign prostatic hyperplasic glandular epithelial cell line.Methods Male spontaneously hypertensive rats were raised to 29 weeks,and then evaluated the situation of BPH with HE staining.The prostate tissue from ventral prostate lobe was aseptically removed,dissected,minced,and then dissociated in collagenase type Ⅰ.Isolated cells were collected,seeded in WAJC-404 and PrEGM medium separately,then cultured and passaged.Specificity of primitive cultured prostatic epithelial cells was identified by cell immunochemistry with CK8/18,and the cell growth curves were drawn.Then the situation of growth of the two prostatic hyperplasic glandular epithelial cell lines were analysed and compared.Results The prostatic hyperplasic glandular epithelial cell lines of the spontaneously hypertensive rats in WAJC-404 and PrEGM medium were successfully primarily cultured,purified and passaged in vitro.Cell immunochemistry proved that the cell lines specifically express cytokeratin 8/18.Cell growth curve showed that prostatic epithelial cells in PrEGM,compared with prostatic epithelial cells in WAJC-404,possessed better cell morphology,more exuberant cell vitality,faster growth rate to enter the logarithmic growth period(4 d vs.7 d)and higher peak of cell growth curve(15.3× 104/ml vs.12.8×104/ml).Conclusions Rat primary benign prostatic hyperplasic glandular epithelial cell line can be established conventionally in vitro.PrEGM medium is more suitable for primary culture of the rat benign prostatic hyperplasic glandular epithelial cell line than WAJC-404 medium.

Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.

This article was aimed to study effects of aqueous extracts and all chemical split fractions ofMori Cortex on hypoglycemic effect of diabetic mice model. Intra-peritoneal injection of 170 mg·kg-1 streptozocin (STZ) was given to male Kunming mice to establish type I diabetes mode. Continuous administration of medication was given for 4 weeks. And then, indicators such as body weight, water intake, food intake, fasting plasma glucose (FBG), insulin, C-peptide, total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c), and low density lipoprotein cholesterol (LDL-c) were detected. Pathological morphology of the liver and pancreas were observed by light microscopy. The results showed that high-dose group ofM. Cortex aqueous extracts can improve weight loss of type I diabetic mice, significantly reduce water intake and food intake, reduce FBG, TC, TG and LDL-c levels in different degrees (P<0.05 orP<0.01), and increase C-peptide and HDL-c levels (P<0.05 orP<0.01). When dosages of 30% ethanol fraction and fatty oil fraction were only about 1/2 and 1/4 ofM.Cortex aqueous extracts, we found that it can improve lipid disorder status,repair liver cells, and improve liver tissue damage. Its effect was superior to M. Cortex aqueous extracts. It was concluded thatM. Cortexaqueous extracts showed a better hypoglycemic effect. The effective component parts were 30% ethanol fraction and fatty oil fraction. Its hypoglycemic mechanism may be related to the promotion of insulin secretion, regulation of blood lipid disorders, as well as the protection of liver structure and function.

Objective To describe the clinical, neuroimaging and genetic profiles of amyotrophic lateral sclerosis with frontotemporal lobe degeneration ( ALS-FTLD).Methods From August 2011 to May 2015, patients with FTLD or other types of neurodegenerative dementia were physically examined in detail and electromyography was performed to those with suspected dysarthria, limb atrophy or weakness.Cognitive and behavioral screenings were performed to all ALS patients.Patients with ALS-FTLD entered further analysis of neuroimaging and genetics.Results Among the 8 patients diagnosed as ALS-FTLD, 4 patients began with personality change or amnesia, while diseases in the remaining 4 cases began with limb weakness or dysarthria.Dementia type of 7 cases was behavioral variant FTLD ( bvFTD) and 1 case was diagnosed as semantic dementia.Electromyography of all the 8 patients showed diffuse neurogenic changes.Constructional neuroimaging of 6 patients showed cerebral atrophy predominantly in frontal and temporal lobes.Fluorodeoxyglucose-positron emission tomography was conducted in 5 patients, indicating hypometabolism mainly in frontal and ( or) temporal lobes.NeuroQ analysis revealed that bilateral frontal lobes were the most hypometabolic areas for ALS-FTLD.Among 4 patients who underwent genetic screening, 1 patient was C9ORF72 mutation carrier.Conclusions bvFTD is the major type of dementia in the context of ALS.Metabolic neuroimaging could assist accurate diagnosis, and it reveals that bilateral frontal lobes are the most hypometabolic areas for ALS-FTLD.C9ORF72 gene mutation is an important pathogenic mutation for ALS-FTLD, although it is rare in Chinese population.

Objective To investigate the effectiveness and safety of coaxial catheter technique in carotid artery stent implantation via radial artery approach.Methods The general and clinical data of patients,who underwent carotid artery stent implantation via radial artery approach at the Department of Neurology,Daxing Teaching Hospital of Capital Medical University of China between January 2021 and October 2022,were retrospectively analyzed.During the operation,coaxial catheter technology was used to make a 6F catheter inserting into the target vessel for performing carotid stent implantation,and the rate of successful catheter placement,surgical success rate,and perioperative complications were analyzed.Results A total of 40 patients,who underwent carotid artery stent implantation via radial artery approach,were enrolled in this study.The involved vessels included left internal carotid artery(n=16),right internal carotid artery(n=24),type Ⅰaortic arch(n=13),type Ⅱ aortic arch(n=20),type Ⅲ aortic arch(n=7),and bovine aortic arch(n=1).The rate of successful catheter placement was 100％,the surgical success rate was 95％,and no procedure-related complications occurred.The time spent on surgery was(34.4±13.6)min.No patients developed symptoms of cerebral infarction or myocardial infarction in 30 days after the operation.Conclusion The use of coaxial catheter technology can make the catheter inserting into the target vessel quickly and avoid repeated catheter exchange.Coaxial catheter technology is safe and effective in performing carotid artery stent implantation via radial artery approach.(J Intervent Radiol,2023,32:1169-1173)

Despite its dual role in determining cell fate in a wide array of solid cancer cell lines, autophagy has been robustly shown to suppress or kill acute myeloid leukemia cells via degradation of the oncogenic fusion protein that drives leukemogenesis. However, autophagy also induces the demise of acute leukemia cells that do not express the known fusion protein, though the molecular mechanism remains elusive. Nevertheless, since it can induce cooperation with apoptosis and differentiation in response to autophagic signals, autophagy can be manipulated for a better therapy on acute myeloid leukemia.

Objective To describe and analyze the level and variation trend of mortality of female genital malignancies in China from 2004 to 2016, so as to provide scientific evidence for the formulation and implementation of cancer prevention and control measures.Methods The mortality data of cervical cancer, corpus cancer and ovarian cancer were selected from the mortality monitoring data of the national disease monitoring system, the crude mortality and standardized mortality rates were calculated respectively, the annual change trend was analyzed by Joinpoint software.Results From 2004 to 2016, the mortality rate of cervical cancer in Chinese women increased significantly. The mortality trend obviously accelerated after 2011(annual percent change, APC = 13.7%), and the mortality rate in rural areas was higher than that in urban areas. The mortality rate of corpus cancer was relatively stable, and showed a downward trend after 2013(APC=-23.5%). Ovarian cancer mortality rate slightly increased, but the death trend was not statistically significant.Conclusions From 2004 to 2016, the mortality of corpus cancer in Chinese women had improved, the mortality of cervical cancer was still relatively serious, and there were differences between urban and rural areas.

Objective To investigate the correlation between the polymorphism of 4 coagulation-related genes, rs1799963 （coagulation factor V gene Leiden）, rs6025 （prothrombin gene G20210A）, rs1042579 （thrombomodulin protein gene c.1418C>T） and rs1801131 （methylenetetrahydroflate reductase gene） and lower extremity deep venous thrombosis （LEDVT）. Methods The 4 genotypes mentioned above of 150 LEDVT patients and 153 healthy controls were detected by the kompetitive allele specific polymerase chain reaction （KASP）, then related blood biochemical indicators were collected, binary Logistic regression was established to screen the independent risk factors of LEDVT, and the correlation between polymorphism of 4 coagulation-related genes and LEDVT and its indicators under different genetic modes after adjusting confounding factors were analyzed. Results Five variables, D-dimer, fibrinogen degradation product, homocysteine, sex and age might be the risk factors of LEDVT. These variables were put into 4 genetic inheritance models, and adjusted in binary Logistic regression. The results suggested that the mutations of rs1042579 were correlated with LEDVT under dominant inheritance mode. Conclusion The gene polymorphism of rs1799963, rs6025 and rs1801131 has no significant correlation with the formation of LEDVT. The gene polymorphism of rs1042579 plays a role under dominant inheritance mode, and might be an independent risk factor for formation of LEDVT.
