To study the clinical correlation between fasting plasma glucose, lipid metabolism, prostate-specific antigen and prostate volume in patients with benign prostatic hyperplasia, and to explore the combined effect as diagnostic indicators. A total of 108 patients with benign prostatic hyperplasia treated in Beijing University of Chinese Medicine Third Affiliated Hospital from June 2021 to March 2023 were retrospectively analyzed as the hyperplasia group, and 98 healthy physical examination personnel were selected as the control group during the same period. Compare the differences in levels of fasting plasma glucose (FPG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), small and dense low-density lipoprotein cholesterol (sdLDL-C), homocysteine, lipoprotein a (LPa), prostate specific antigen (PSA), and free prostate specific antigen (fPSA) between two groups of patients. Using Pearson analysis method to analyze the correlation between the above indicators and the size of prostate volume in patients with benign prostatic hyperplasia; using multiple linear regression to analyze the influencing factors of prostate volume enlargement; draw receiver operating characteristic (ROC) curves and analyze the application value of individual and combined detection of HDL, FPG, PSA, and fPSA. The results showed that there were significant differences in HDL, FPG, PSA, and fPSA levels between the control group and the proliferative group( P<0.05). The size of prostate volume is negatively correlated with HDL( r=-0.183, P<0.05) and positively correlated with FPG ( r=0.202, P<0.05), PSA( r=0.412, P<0.05), and fPSA( r=0.425, P<0.05). The results of multiple linear regression analysis showed that HDL( P=0.000), FPG( P=0.048), PSA( P=0.044), and fPSA ( P=0.012) were risk factors for increased volume of benign prostatic hyperplasia; ROC curve analysis shows that the AUC of HDL, FPG, PSA, and fPSA combined detection is 0.823, which is better than individual detection. In conclusion,HDL, FPG, PSA, fPSA has close correlation with hyperplasia of prostate, the joint detection may has better prediction for benign prostatic hyperplasia.

AIM: To investigate the mechanism of elemene synergistic bortezomib against multiple myeloma based on ROS-NF-κB-p38MAPK signaling pathway. METHODS: CCK-8 assay was used to detect cell activity. Nude mice were randomly divided into control group, bortezomib (BTZ) group, elemene (ELE) group and combination group. Each group was treated with BTZ, ELE and BTZ combined with ELE, respectively. Tunel staining was performed to observe the apoptosis of tumor tissues. The expressions of Caspase-3, Bcl-2, NF-κB and p38 MAPK were detected by Western Blot. Cell cycle, apoptosis and reactive oxygen species (ROS) expression were detected by flow cytometry using human myeloma U266 cells. RESULTS: When 4.0 μmol/L ELE combined with 50 nmol/L BTZ treated U266, the cell activity was significantly reduced compared with that of NC, BTZ and ELE groups (P< 0.05). The tumor volume of nude mice in BTZ group, ELE group and combined group was significantly reduced compared with the control group (P <0.05), and the combined group was the smallest. Tunel staining results showed that the apoptosis level in the control group was lower than that in the BTZ group, ELE group and the combined group (P<0.05), and the combined group had the lowest apoptosis level. Compared with the control group, the expressions of Caspase-3 and p38 MAPK in BTZ group, ELE group and combination group were significantly increased, while the expression of Bcl-2 was significantly decreased. The apoptosis level and expression of ROS in BTZ group, ELE group and the combined group was significantly increased compared with the control group (P<0.05). CONCLUSION: ELE can enhance the role of BTZ in promoting apoptosis of myeloma cells, which may be achieved by regulating ROS/NF-κB/p38 MAPK signaling pathway to enhance the level of apoptosis of tumor cells to achieve anti-tumor effect.

Objective    To report our clinical experience and outcomes of thoracic endovascular aortic repair (TEVAR) for acute Stanford type A dissection using ascending aorta replacement combined with implantation of a fenestrated stent-graft of the entire aortic arch through a minimally invasive technique. Methods    From 2016 to 2020 in our hospital, 24 patients (17 males and 7 females, aged 45-72 years) with complicated Stanford type A aortic dissection, underwent replacement of the proximal ascending aorta with TEVAR. None of the patients with dissection involved the three branches of the superior arch, and all patients were replaced with artificial blood vessels of the ascending aorta under non-hypothermic cardiopulmonary bypass, preserving the arch and the three branches above the arch, and individualized stent graft fenestration. Results    Surgical technical success rate was 100.0%. There was no intraoperative complication or evidence of endo-leak in 1 month postoperatively. Hospital stay was 10±5 d. During postoperative follow-up, the stent was unobstructed without displacement, the preserved branch of the aortic arch was unobstructed, and the true lumen of the descending aorta was enlarged. Conclusion     This hybrid technique by using TEVAR with fenestrated treatment is a minimally invasive and effective method to treat high-risk patients with acute Stanford type A aortic dissection.

Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide, such as the on-going outbreak of the novel coronavirus SARS-CoV-2. Herein, we identified two potent inhibitors of human DHODH, S312 and S416, with favorable drug-likeness and pharmacokinetic profiles, which all showed broad-spectrum antiviral effects against various RNA viruses, including influenza A virus, Zika virus, Ebola virus, and particularly against SARS-CoV-2. Notably, S416 is reported to be the most potent inhibitor so far with an EC of 17 nmol/L and an SI value of 10,505.88 in infected cells. Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells. This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.

Objective To analyse the relationships between islet β-cell function and infection,inflammation and major organ function in multiple organ dysfunction syndrome (MODS) patients with severe traumatic hemorrhage.Methods A total of 187 cases of MODS patients hospitalized in the 94th Hospital of PLA from January 2013 to January 2016 were selected,and were divided into the MODS survival group (MODS-S group,104 cases) and MODS dead group (MODS-D group).Other 100 healthy subjects were selected as the control group.The fasting blood glucose (GLU0) and insulin (INS0) levels,blood glucose (GLU30) and insulin (INS30) levels after 30 min of glucose loading,and levels of soluble triggering receptor expressedon myeloid cells-1 (sTREM-1),tumor necrosis factor-α (TNF-a),interleukin-6 (IL-6),alanine aminotransferase (ALT),creatinine (Cre) and creatine kinase isoenzyme (CK-MB) in different groups were determined.The insulin-β-cell function was evaluated by homeostasis model assessment of β-cell function (HOMA-β) index and ratio of insulin increment and blood glucose increment after 30 min of glucose loading (ΔINS30/ΔGLU30),and their relationships to other indexes,including sTREM-1,TNF-α,IL-6,GLU0,ALT,Cre and CK-MB,in MODS patients with severe traumatic hemorrhage were analysed.Results The HOMA-β and AINS30/AGLU30 ratio in the MODS-D group were lower than those in the MODS-S group,and levels of sTREM-1,TNF-α,IL-6,ALT,Cre and CK-MB in the MODS-D group were higher than those in the MODS-S group,there were statistically significant differences (P＜0.01).In MODS patients with severe traumatic hemorrhage,HOMA-β and ΔINS30/AGLU30 was both negatively correlated with sTREM-1,TNF-α,IL-6,GLU0,ALT,CreandCK-MB (r=-0.356 4,-0.532 1,-0.345 8,-0.772 1,-0.762 5,-0.684 8,-0.606 4;r=-0.428 5,-0.567 8,-0.487 0,-0.743 6,-0.781 7,-0.717 6,-0.640 1,P＜0.01).Conclusion MODS patients with severe traumatic hemorrhage have islet β-cell dysfunction which may be used as a prognostic and diagnostic indicator.

OBJECTIVE:To study the pharmacokinetics of the active ingredients of Shenmai injection,including ginsenoside Rg1 and ginsenoside Re,in normal Beagle dogs and those with myocardial ischemia. METHODS:6 Beagle dogs were given isopro-terenol hydrochloride (1.1 mg/kg) sc to establish the model of myocardial ischemia (model group). Another 6 Beagle dogs were given isometric normal saline (2.2 ml/kg) sc as controls group. The two groups of dogs respectively received corresponding drugs sc at 8:00 am and 13:00 pm on day 1 and at 8:00 am on day 2. Each group of dogs were given Shenmai injection(1.6 ml/kg)iv 1 h after administration on day 2,and such intravenous drip lasted for about 1 h. Blood was collected from each group 0,0.25, 0.5,0.75,1(the end of iv),1.5,2,3,4,6,8,12 and 24 h from the start of iv. Liquid chromatography-mass spectrometry was adopted to determine the concentrations of ginsenoside Rg1 and ginsenoside Re in blood,and WinNonlin 6.3 was used to calculate pharmacokinetic parameters for comparison. RESULTS:For ginsenoside Re in the dogs of the model group,t1/2 was(2.69±1.12) h,AUC0-24 h was(2 060.78±812.18)h·μg/L,Vz was(46.16±20.98)ml and CL was(9.02±4.45)ml/h;compared to the normal control group,AUC0-24 h was much greater and Vz and CL were significantly lower,showing a statistically significant difference(P<0.05). No significant difference in the pharmacokinetic parameters of ginsenoside Rg1 was shown between 2 groups(P>0.05). CON-CLUSIONS:Myocardial ischemia may affect the removal of ginsenoside Re in Beagle dogs,but has no effect on the pharmacoki-netic process of ginsenoside Rg1.

Objective To compare the cumulative analgesic effects of electroacupuncture at Sanyinjiao (SP6), Xuanzhong (GB39) and non-acupoint in treating primary dysmenorrhea. Method By adopting a multi-centered randomized controlled study method, 501 patients recruited from Dongzhimen Hospital of Beijing University of Chinese Medicine, China-Japan Friendship Hospital, Beijing Hospital of Traditional Chinese Medicine of Capital Medical University, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine, Huguosi Hospital of Chinese Medicine of Beijing University of Chinese Medicine and the Outpatient of Shandong University of Traditional Chinese Medicine were randomized into a Sanyinjiao group, a Xuanzhong group, and a non-acupoint group, 167 subjects in each group. The electroacupuncture intervention was applied when dysmenorrhea flared up and the Visual Analogue Scale (VAS) ≥40 mm, with frequency at 2/100 Hz and intensity during patient’s endurance, 30 min each time, once a day, and for successive 3 d. Before the first treatment, 30 min after the first treatment, and respectively prior to the second and third treatment, VAS was used to measure the pain intensity. Meanwhile, the Retrospective Symptom Scale (RSS-COX 2) was investigated before the first treatment, right after the removal of needles for the first treatment, before the second and third treatment. Result The decrease of VAS in Sanyinjiao group was more significant than that in Xuanzhong group and non-acupoint group (MD=﹣2.92 mm, P=0.028; MD=﹣3.47 mm, P=0.009), while there was no significant difference between Xuanzhong group and non-acupoint group (MD=﹣0.56 mm, P=0.674); there were no significant differences in comparing the RSS-COX2 total score among the three groups (P=0.086). Conclusion Sanyinjiao (SP6) can produce a more significant cumulative analgesic effect for primary dysmenorrhea patient than Xuanzhong and non-acupoint, and the effects of Xuanzhong and non-acupoit are equivalent.
