ABSTRACT

ObjectiveTo investigate the expression of glial cell line-derived neurotrophic factor (GDNF) and androgen receptor (AR) in testicular peritubular cells (TPCs) of cryptorchidism mouse models and explore the theoretical significance of cryptorchidism-induced spermatogenesis dysfunction. MethodsA total of 30 five-week-old male ICR rats were divided randomly by using random number table method into 6 groups. Cryptorchidism was surgically induced in 3 randomly selected groups and the other 3 groups underwent sham surgery as the control groups. On days 4, 7 and 14 after surgery, we harvested the mice testes of the 3 groups and their corresponding control groups, then measured the testicular volumes, analyzed the testicular histopathology and detected the mRNA and protein expression levels of AR and GDNF in TPCs by immunofluorescence, real-time PCR and Western blot. ResultsIn normal control groups, on days 4, 7 and 14 after surgery, the testicular volumes were (125.58±19.22) mm3,(123.45±20.12) mm3, (140.09±13.62) mm3 , respectively. Clear layers of spermatogenic cells were well arranged and abundant sperm cells were found. Peritubular cells were morphologically homogeneous, with slim-spindle appearance and normal cell thickness. The mRNA expression levels of AR were 1.00±0.05, 1.06±0.07 and 1.19±0.13; GDNF mRNA 1.00±0.04, 1.09±0.05, and 1.10±0.07. The protein expression levels of AR were 1.01±0.01, 0.79±0.02 and 1.01±0.04; GDNF protein (18.68±0.43) pg/mL, (14.39±0.36) pg/mL and (16.88±0.37) pg/mL. In cryptorchidism groups, on days 4, 7 and 14 after surgery, the testicular volumes were (115.64±3.91) mm3, (69.51±14.97) mm3 and (44.86±5.56) mm3, respectively. Spermatogenic cells were disorganized, seminiferous tubules were disrupted, peritubular cells shrank, bent and fractured. The mRNA expression levels of AR were 0.76±0.06, 0.53±0.04, and 0.29±0.02; GDNF mRNA 0.72±0.05, 0.42±0.02 and 0.30±0.03. The protein expression levels of AR were 0.54±0.02, 0.98±0.04 and 0.31±0.01; GDNF protein (8.50±0.34) pg/mL, (17.44±0.32) pg/mL and (6.83±0.34) pg/mL. Statistically significant differences (P < 0.05) were found in 7-day and 14-day testicular volumes between control and cryptorchidism groups but not in the 4-day testicular volume (P > 0.05). Testicular volumes, AR and GDNF mRNA and protein expression in control groups had no statistically significant difference (P > 0.05), while those in cryptorchidism groups showed a trend of gradual decline in the amount and the differences between groups were statistically significant (P < 0.05). ConclusionsIn surgery-induced cryptorchidism mice, after the induction, the expression of AR and GDNF in TPCs showed a gradual decrease over time. AR and GDNF play a major role in mediating the TPCs damage in cryptorchidism. This study provides a theoretical basis for mechanism researches of cryptorchidism-induced spermatogenesis dysfunction.

ABSTRACT

OBJECTIVE@#To investigate the optimal duration of dual antiplatelet therapy (DAPT) in patients with diabetes mellitus (DM) requiring complex percutaneous coronary intervention (PCI).@*METHODS@#A total of 2403 patients with DM who underwent complex PCI from January to December 2013 were consecutively enrolled in this observational cohort study and divided according to DAPT duration into a standard group (11-13 months, n = 689) and two prolonged groups (13-24 months, n = 1133; > 24 months, n = 581).@*RESULTS@#Baseline characteristics, angiographic findings, and complexity of PCI were comparable regardless of DAPT duration. The incidence of major adverse cardiac and cerebrovascular event was lower when DAPT was 13-24 months than when it was 11-13 months or > 24 months (4.6% vs. 8.1% vs. 6.0%, P = 0.008), as was the incidence of all-cause death (1.9% vs. 4.6% vs. 2.2%, P = 0.002) and cardiac death (1.0% vs. 3.0% vs. 1.2%, P = 0.002). After adjustment for confounders, DAPT for 13-24 months was associated with a lower risk of major adverse cardiac and cerebrovascular event [hazard ratio (HR) = 0.544, 95% CI: 0.373-0.795] and all-cause death (HR = 0.605, 95% CI: 0.387-0.944). DAPT for > 24 months was associated with a lower risk of all-cause death (HR = 0.681, 95% CI: 0.493-0.942) and cardiac death (HR = 0.620, 95% CI: 0.403-0.952). The risk of major bleeding was not increased by prolonging DAPT to 13-24 months (HR = 1.356, 95% CI: 0.766-2.401) or > 24 months (HR = 0.967, 95% CI: 0.682-1.371).@*CONCLUSIONS@#For patients with DM undergoing complex PCI, prolonging DAPT might improve the long-term prognosis by reducing the risk of adverse ischemic events without increasing the bleeding risk.

ABSTRACT

Objective:To analyze the impact of baseline quantification of hepatitis B core antibody (qHBcAb) on prognosis of patients with hepatitis B virus (HBV) related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 91 HBV-ACLF patients (HBV-ACLF group), who admitted to Wuxi No.5 People′s Hospital from July 1, 2019 to December 30, 2021, were included in this study. Fifty chronic hepatitis B (CHB) patients (CHB group) and 50 chronic HBV carriers (HBV carrier group) were enrolled as controls. Baseline clinical data such as qHBcAb, blood routine examination biochemical, and coagulation indices, HBsAg, hepatitis B e antigen (HBeAg), HBV DNA levels were recorded and analyzed retrospectively. The HBV-ACLF, HBsAg and HBV-DNA data were converted logarithmically. Patients were followed-up for 90 days. Cox regression was used to analyze the correlation between HBV-ACLF and survival outcome; survival rate was estimated by the Kaplan-Meier method; receiver operating characteristic (ROC) curve was used to evaluate the predictive value of baseline qHBcAb for the prognosis in patients with HBV-ACLF.Results:The baseline qHBcAb level in HBV-ACLF patients was (4.83±0.42) IU/ml, which was significantly higher than that in the CHB group [(4.59±0.54) IU/ml] and chronic HBV carrier group [(3.86±0.74) IU/ml] (all P<0.05). At the end of 90 days follow-up, 46 patients (50.55%) survived, and 45 patients (49.45%) died in the HBV-ACLF group. The baseline qHBcAb level was significantly higher in the survival group [(4.93±0.22) IU/ml] than in the death group [(4.70±0.52) IU/ml, P<0.01]. Significant differences were also found in the alpha fetoprotein, international normalized ratio, prothrombin activity, antithrombin Ⅲ activity, platelet, end-stage liver disease model score and hepatic encephalopathy complication between the two groups ( P<0.05). Cox regression analysis showed that the baseline qHBcAb was an independent risk factor affecting the 90-day survival of HBV-ACLF patients [hazard ratio=0.027,95% confidence interval ( CI) 0.001-0.696, P<0.05]. The area under the ROC curve of baseline qHBcAb level for predicting the 90-day survival outcome of HBV-ACLF patients was 0.639 (95% CI 0.525-0.752, P<0.05), with a cut-off value of 4.89 IU/ml. The cumulative survival rate of patients with baseline qHBcAb≥4.89 IU/ml was higher than that of patients with baseline qHBcAb<4.89 IU/ml ( P<0.05). Conclusions:Higher baseline qHBcAb level is associated with favorable outcome of HBV-ACLF patients and baseline qHBcAb may be used as a new biomarker to predict the clinical outcome of HBV-ACLF patients. HBV-ACLF patients with serum qHBcAb lower than 4.89 IU/ml face increased risk of short-term death.

ABSTRACT

OBJECTIVE@#This study investigated trends in the study of phytochemical treatment of post-traumatic stress disorder (PTSD).@*METHODS@#The Web of Science database (2007-2022) was searched using the search terms "phytochemicals" and "PTSD," and relevant literature was compiled. Network clustering co-occurrence analysis and qualitative narrative review were conducted.@*RESULTS@#Three hundred and one articles were included in the analysis of published research, which has surged since 2015 with nearly half of all relevant articles coming from North America. The category is dominated by neuroscience and neurology, with two journals, Addictive Behaviors and Drug and Alcohol Dependence, publishing the greatest number of papers on these topics. Most studies focused on psychedelic intervention for PTSD. Three timelines show an "ebb and flow" phenomenon between "substance use/marijuana abuse" and "psychedelic medicine/medicinal cannabis." Other phytochemicals account for a small proportion of the research and focus on topics like neurosteroid turnover, serotonin levels, and brain-derived neurotrophic factor expression.@*CONCLUSION@#Research on phytochemicals and PTSD is unevenly distributed across countries/regions, disciplines, and journals. Since 2015, the research paradigm shifted to constitute the mainstream of psychedelic research thus far, leading to the exploration of botanical active ingredients and molecular mechanisms. Other studies focus on anti-oxidative stress and anti-inflammation. Please cite this article as: Gao B, Qu YC, Cai MY, Zhang YY, Lu HT, Li HX, Tang YX, Shen H.

ABSTRACT

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

ABSTRACT

Objective:To compare the influence of single and staged percutaneous coronary intervention (PCI) on long-term prognosis in patients with multi-vessel coronary artery disease.Methods:Using prospective research methods, 1 832 patients with multi-vessel coronary artery disease from January to December 2013 in Fuwai Hospital, Chinese Academy of Medical Sciences were selected. According to the time of PCI, the patients were divided into single PCI group (1 218 cases) and staged PCI group (614 cases). The patients were followed up for 2 years, the primary endpoint was major cardiovascular and cerebrovascular event (MACCE), including target vessel-related myocardial infarction (TV-MI), target vessel-related revascularization (TVR), cardiogenic death and stroke, and the secondary endpoint was stent thrombosis. The propensity score matching (PSM) was applied to balance the discrepancies between 2 groups, and the baseline and follow-up data were compared. The Kaplan-Meier survival curves were drawn to evaluate the survival rates events; multifactor Cox proportional risk regression was used to analyze whether staged PCI was an independent risk factor for the endpoint events.Results:The in-hospital stay, duration of procedure and synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score in single PCI group were significantly lower than those in staged PCI group: (5.54±3.09) d vs. (9.50±4.06) d, (43.12±28.55) min vs. (79.54±44.35) min, (14.04±7.63) scores vs. (18.51±7.79) scores, and there were statistical differences ( P<0.01); there were no statistical difference in complete revascularization rate and SYNTAX score after PCI between 2 groups ( P>0.05). Based on 2-year follow-up, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.5% (6/1 218) and 2.0% (12/614) vs. 0.4% (5/1 218), and there were statistical differences ( P<0.01). Kaplan-Meier survival curves analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were better than those in staged PCI group (99.5% vs. 97.9% and 99.6% vs. 98.0%, P<0.01). Multifactor Cox proportional risk regression analysis results showed that staged PCI was an independent risk factor for stent thrombosis ( HR = 3.91, 95% CI 1.25 to 12.18, P = 0.019). After PSM, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.7% (4/614) and 2.0% (12/614) vs. 0.5% (3/614), and there were statistical differences ( P<0.05); Kaplan-Meier survival curve analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were significantly higher than those in staged PCI group: (99.3% vs. 97.9% and 99.5% vs. 98.0%, P<0.05); multifactor Cox proportional risk regression analysis results showed that staged PCI was not an independent risk factor of stent thrombosis ( HR = 2.29, 95% CI 0.58 to 9.00, P = 0.234). Both before and after PSM, there were no evidences for interaction between the type of angina pectoris and staged PCI ( P>0.05). Conclusions:Although a seemingly increase exists in the incidence of TV-MI and stent thrombosis in the staged PCI group, staged PCI is an independent risk factor neither for MACCE and its components, nor for stent thrombosis. In addition single PCI reduces the in-hospital days and duration of PCI procedure, which may be a relatively reasonable approach to clinical practice.

ABSTRACT

Quetiapine is a psychotropic drug. Excessive use of quetiapine may lead to drowsiness, blurred vision, respiratory depression, hypotension and extrapyramidal reactions. Acute respiratory distress syndrome (ARDS) is rare due to overdose of quetiapine. On 14 February 2020, a patients with coma, respiratory arrest and hypotension due to overdose of quetiapine were admitted to our hospital. After receiving mechanical ventilation、plasma adsorption and anti-inflammatory treatment, the patient's consciousness turned clear, the machine was successfully removed and extubated, and the patient's condition was improved and discharged from hospital. We analyzed the clinical data of the patient with quetiapine poisoning, and discussed the clinical symptoms and chest CT characteristics of ARDS caused by quetiapine poisoning, in order to improve the understanding of quetiapine poisoning and improve the success rate of rescue.

ABSTRACT

With the rise of incidence, fatality rate, and number of young cases, diabetes mellitus has been one of the seven major diseases threatening human health. Although many antidiabetic drugs(oral or for injection) are available, the majority have serious side effects during the long-term use. Thus, it is of particularly vital to develop new drugs with low risk and definite effect. Psoraleae Fructus, a traditional medicinal widely used in the folk, has hypoglycemic, anti-osteoporosis, antitumor, estrogen-like, and anti-inflammatory effects. Thus, it has great clinical application potential. Chinese medicine and the active ingredients, characterized by multiple targets, multiple pathways, and multiple effects in the treatment of diabetes mellitus, have distinct advantages in clinical application. However, the safety of Chinese medicine remains to be a challenge, and one of keys is to clarifying the mechanism of a single Chinese medicinal and its active ingredients. With the method of literature research, this study summarized and analyzed the hypoglycemic mechanisms of Psoraleae Fructus and its main active ingredients over the last decade: regulating glucose metabolism, improving insulin resistance, and directly acting on pancreatic β-cells. The result is expected to serve as a reference for further research on the effects of Psoraleae Fructus and its main chemical constituents in lowering blood glucose and preventing diabetes mellitus and the clinical application.

ABSTRACT

OBJECTIVE@#To delineate the onset and recurrence characteristics of noncardiogenic ischemic stroke patients in China.@*METHODS@#A prospective, multicenter and registry study was carried out in 2,558 patients at 7 representative clinical sub-centers during November 3, 2016 to February 17, 2019. A questionnaire was used to collect information of patients regarding CM syndromes and constitutions and associated risk factors. Additionally, stroke recurrence was defined as a primary outcome indicator.@*RESULTS@#A total of 327 (12.78 %) patients endured recurrence events, 1,681 (65.72%) were men, and the average age was 63.33 ± 9.45 years. Totally 1,741 (68.06%) patients suffered first-ever ischemic stroke, 1,772 (69.27%) patients reported to have hypertension, and 1,640 (64.11%) of them reported dyslipidemia, 1,595 (62.35%) patients exhibited small-artery occlusion by The Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. Specifically, 1,271 (49.69%) patients were considered as qi-deficient constitution, and 1,227 (47.97%) patients were determined as stagnant blood constitution. There were 1,303 (50.94%) patients diagnosed as blood stasis syndrome, 1,280 (50.04%) patients exhibited phlegm and dampness syndrome and 1,012 (39.56%) patients demonstrated qi deficiency syndrome. And 1,033 (40.38%) patients declared intracranial artery stenosis, and 478 (18.69%) patients reported carotid artery stenosis. The plaque in 1,508 (41.36%) patients were of mixed. Particularly, 41.09% of them demonstrated abnormal levels of glycated hemoglobin levels.@*CONCLUSIONS@#Recurrence in minor and small-artery stroke cannot be ignored. Hypertension, dyslipidemia, abnormal HbA1c, intracranial artery stenosis and carotid plaque were more common in stroke patients. Particularly, phlegm-dampness and blood stasis syndromes, as well as qi deficiency and blood stasis constitutions, were still the main manifestations of stroke.

ABSTRACT

【Objective】 To study and analyze the characteristics of 56-60 years old apheresis platelet donors and the results of pre-donation blood testing in Tianjin, so as to provide reference for the management of blood stations and the maintenance and retention of blood donors. 【Methods】 The information of platelet donors were collected by Tianjin Blood Center from July 1, 2012 to June 30, 2021.The donors aged 56-60(the observation group) were compared with donors aged 18-55(the control). The number of blood donations, male to female ratio, donation frequency, proportion of two-therapeutic-amount donation, rate of deferred donation, incidence of adverse reactions to blood donation, etc of the two groups were studied. The pre-donation test results of the two groups were also compared through the analysis of the unqualified factors of blood routine. 【Results】 From 2012 to 2021, there were 2 837 platelet donors aged 56-60 in Tianjin, and the donation frequency and proportion of two-therapeutic-amount donation were significantly higher than those in the control. The blood routine indexes were significantly different between two groups, but all fluctuated within the normal range(P<0.05). More donors in the observation group than the control were deferred due to unqualified blood routine indexes, mainly caused by Hb deferral. 【Conclusion】 In the past 9 years, the number of apheresis platelet donors aged 56-60 in Tianjin has been stablely increasing. Elderly donors always meet the health requirements of donations according to the results of blood tests. Close monitor of the blood routine indexes, however, should be paid to such population to ensure the elderly donor health and donation safety.

ABSTRACT

Objective To explore the potential adverse reactions of acalabrutinib by mining and analyzing the pharmacovigilance signal of acalabrutinib, to provide a reference for clinically safe and rational drug use. Methods Data related to acalabrutinib in the FAERS database were searched, and pharmacovigilance signals were obtained using the disproportionality measurement. Results A total of 3, 155 reports of adverse events with acalabrutinib as the primary suspected drug were extracted, and 73 warning signals were detected involving 15 system organ classifications, 36 of which were not included in the drug instructions of acalabrutinib. The strong signals of acalabrutinib were mainly concentrated in various inflammatory and bleeding, anemia, contusion, atrial fibrillation, and so on. The largest number of system organ classification signals were focused on the blood and lymphatic system disorders, investigations, infections, and so on. In addition, the drug may cause tachycardia, brittle nails, and other warning signs. Through further analysis of gender-related adverse events, there were a total of 49 high-risk signals with gender differences found. Herein, male patients should pay attention to adverse reactions in bleeding, heart, urinary system, hypertension, and so on; meanwhile, female patients should be alert to adverse reactions in liver function, skin inflammation, and so on. Conclusion A total of 36 drug warning signs that are not mentioned in the instructions for acalabrutinib are mined using FAERS, and blood, infection, and cardiac toxicity require special attention. Thus, these signals should be detected promptly for effective prevention in clinical medication to reduce the risk of medication use for patients.

ABSTRACT

Objective To perform a network meta-analysis (NMA) for the efficacy of 11 drugs in preventing chronic peripheral neuropathy induced by platinum and taxane (PTIPN). Methods PubMed, Cochrane library, Embase, CNKI, WanFang database and VIP database were searched up to February 2021 for relevant randomized controlled trials (RCTs) addressing the drugs to prevent PTIPN. After extracting relevant data, Stata 14.0 and ADDIS 1.16.6 softwares were used for statistical analysis. Results A total of 70 studies involving 6201 patients were included. The results of network Meta-analysis showed that amifostine, ganglioside, Huangqi Guizhi Wuwu decoction (HQGZT), vitamin E, calcium and magnesium infusion and omega-3 fatty acids were superior to placebo or blank groups in reducing the incidence of overall or severe PTIPN. The rank probability plot and the SUCRA calculation results suggested that amifostine, HQGZT and omega-3 fatty acids were in first order. The differences between the 11 drugs and placebo or blank groups were not statistically significant, except for amifostine which was reported to aggravate the adverse reactions of nausea and vomiting and hypotension in patients. Conclusion HQGZT, Ganglioside, Vitamin E, omega-3 fatty acids, calcium and magnesium infusion and glutathione can reduce the occurrence of PTIPN, and HQGZT has the highest efficiency.

ABSTRACT

OBJECTIVE: To analyze the prevalence and risk factors of hyperuricemia in male pilots.METHODS: By using the convenient sampling method, 1 561 male pilots were selected as the study subjects. Among them, 678 patients with hyperuricemia were taken as the observation group, and 883 pilots without hyperuricemia were taken as the control group. The incidence of hyperuricemia in the two groups was compared. RESULTS: The prevalence of hyperuricemia in male pilots was 43.4%(678/1 561). The pilots in the observation group had higher body mass index(BMI), higher triglyceride(TG), lower high-density lipoprotein cholesterol, higher low-density lipoprotein cholesterol(LDL-C), higher mixed hyperlipidemia and higher non-alcoholic fatty liver disease(NAFLD)(all P<0.05) compared with the control group. The result of multivariate logistic regression analysis showed that high BMI, high TG, high LDL-C and NAFLD were the risk factors for hyperuricemia in male pilots(odds ratios were 1.517, 1.559, 1.384 and 1.782, respectively, all P<0.01), while age≥40 was a protective factor for hyperuricemia(odds ratio was 0.593, P<0.01).CONCLUSION: The prevalence of hyperuricemia in male pilots is relatively high. The prevention and treatment of hyperuricemia in pilots should be strengthened.

ABSTRACT

Objective:To observe effect of Jingulian capsule on the proliferation of human breast cancer MDA-MB-231 cells and investigate its action mechanism against triple negative breast cancer (TNBC). Method:The ingredients of Jingulian capsule were identified by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). The inhibitory effect of Jingulian capsule at different doses (0.125,0.25,0.5,1,and 2 g·L<sup>-1</sup>) against the proliferation of MDA-MB-231 cells were detected by methyl thiazolyl tetrazolium (MTT) assay. After treatment for 24 h, the morphological changes in nuclear apoptosis of MDA-MB-231 cells were detected by Hoechst 33258 staining. The effect of different concentrations of Jingulian capsule on the apoptosis and cycle of MDA-MB-231 cells after different treatment time were determined by flow cytometry. The protein expression levels of Poly-ADP-ribose polymeras (PARP), proto-oncogene c-Myc, cyclin B<sub>1</sub>, and phosphorylated extracellular signal-regulated kinase (p-ERK) in each group were assayed by Western blot. Result:A total of 113 compounds in Jingulian capsule were identified by UPLC-MS/MS. As revealed by MTT assay,compared with blank group,Jingulian capsule (0.125,0.25,0.5,1,2 g·L<sup>-1</sup>) significantly inhibited viability of MDA-MB-231 cells (<italic>P</italic><0.01), with the half maximal inhibitory concentration ( IC<sub>50</sub>) of(0.13±0.02)g·L<sup>-1</sup>. According to flow cytometry,compared with the blank group,Jingulian capsule at 1 g·L<sup>-1</sup> significantly induced the apoptosis of MDA-MB-231 cells (<italic>P</italic><0.05)and Jingulian capsule at 0.5, 1 g·L<sup>-1</sup> obviously increased the number of MDA-MB-231 cells in S phase (<italic>P</italic><0.05,<italic>P</italic><0.01). The results of Western blotting demonstrated that the protein expression levels of PARP,c-Myc,and cyclin B<sub>1</sub> in 0.5, 1 g·L<sup>-1 </sup>Jingulian capsule groups were remarkably down-regulated as compared with those in the blank group(<italic>P</italic><0.01), and the protein expression level of p-ERK in 1 g·L<sup>-1 </sup>Jingulian capsule group was also down-regulated (<italic>P</italic><0.01). Conclusion:Jingulian capsule is able to inhibit the proliferation of MDA-MB-231 cells,induce S phase cell cycle arrest, and promote their apoptosis, which may be related to the inactivation of the MAPK signaling pathway.

ABSTRACT

Objective:To investigate the long-term effect of open reduction and internal fixation and one stage rotator cuff repair in treatment of proximal humeral fractures combined with rotator cuff tear.Methods:A retrospective case series study was performed on clinical data of 40 patients with proximal humeral fractures combined with rotator cuff tear admitted to Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2012 to December 2015. There were 24 males and 16 females, aged 52-93 years [(72.5±10.2)years]. According to Neer classification, there were 7 patients with two-part proximal humerus fractures, 27 with three-part proximal humerus fractures and 6 with four-part proximal humerus fractures. All patients received open reduction and internal fixation using locking plates and one stage rotator cuff repair. Functional shoulder exercises were carried out after operation. Fracture healing and wound healing were observed postoperatively. Shoulder active motion, visual analogue score (VAS) and University of California at Los Angeles (UCLA) shoulder rating scale were assessed and compared before operation and at the last follow-up.Results:All patients were followed up for 4.5-8.5 years [(6.2±1.2)years]. All wounds and fractures healed without infection or nonunion. At the last follow-up, the active forward elevation of affected shoulder was 100°-150° [(121.8±15.8)°], the external rotation with the shoulder in neutral position was 30°-80° [(47.0±15.9)°], the external rotation with the shoulder abduction was 60°-80° [(73. 5±6.2)°], the internal rotation with the shoulder abduction was 60°-80° [(70.5±7.1)°], showing significant differences compared to preoperative 30°-60° [(44.8±11.1)°], 0°-30° [(12.0±10.4)°], 0°-30° [(13.8±7.7)°], 30°-60° [(47.0±8.5)°], respectively (all P<0.01). The VAS was 1 (0, 1)points at the last follow-up, and was 6(5, 6)points before operation ( P<0.01). The UCLA shoulder rating scale was 28-35 points [(31.0±2.3)points] at the last follow-up, compared with preoperative 8-11 points [(10.3±0.8)points] ( P<0.01), and rated as excellent in 10 patients, good in 23 and poor in 7, with the excellent-good rate of 83%. Conclusion:For patients with proximal humeral fractures combined with rotator cuff tear, open reduction and internal fixation and one stage rotator cuff repair can significantly restore the shoulder motion, relieve the pain and recovery shoulder function, and the long-term therapeutic effect is satisfactory.

ABSTRACT

Drug resistance is a major obstacle in the development of effective colorectal cancer (CRC) therapy. Our study aimed to explore the reversal abilities of Jiedu Sangen decoction (JSD) on the 5-fluorouracil (5-FU) resistance and its underlying molecular mechanisms. Expression changes in HIF-1 of CRC tissues were firstly revealed by bioinformatics analysis. Afterwards, cell viabilities of JSD and 5-FU treatments on 5-FU resistant human colon cancer cells (HCT-8/5-FU) were determined. Expressions of phosphoinositide 3-kinase (PI3K), protein kinase B (AKT)/p-AKT, hypoxia-inducible factor 1 (HIF-1α), as well as glycolysis related proteins such as L-lactate dehydrogenase A (LDHA), Glucose transporter type 1 (Glut1), Hexokinase 2 (HKII), and cysteinyl aspartate specific proteinase (Caspase) family members in HCT-8/5-FU cells, HIF-1α silenced HCT-8/5-FU cells and tumor tissues were detected by western blotting. HIF-1α was found over expressed in CRC tissues according to public available datasets in Oncomine. Growth inhibition rates of HCT-8/5-FU cells were increased along with the increase of JSD concentrations. JSD caused down-regulated HIF-1α, PI3K, AKT/p-AKT, HKII and Glut1, as well as up-regulated Caspase3 and Caspase9 in HCT-8/5-FU cells and tumor tissues. In HIF-1α silenced HCT-8/5-FU cells, synergistic group showed significantly reduced expression levels of PI3K, AKT, p-AKT. Additionally, up-regulated expressions of Caspase6 and Caspase7 were observed. JSD combined with 5-FU also exhibited obvious inhibitory efficiency on tumor growth in vivo. JSD may reverse 5-FU resistance by suppressing glycolysis via PI3K/AKT/HIF-1α signaling pathway, thereby inhibiting glycolysis and induce apoptosis to enhance anti-tumor activity.

ABSTRACT

Objective:To explore the correlation between the expression of signaling lymphocyte activation molecule family 6 (SLAMF6) on peripheral blood CD8 +T cells and perforin and granzyme B and the clinical significance in patients with newly diagnosed severe aplastic anemia(SAA). Methods:The indicators of blood routine and bone marrow and peripheral blood samples of 32 newly diagnosed SAA patients admitted to Henan Provincial People′s Hospital from January 2016 to June 2019 were collected for retrospective analysis. Flow cytometry was used to detect the expression of SLAMF6, perforin and granzyme B on samples CD8 +T cell before therapy and 6 months after therapy (11 cases received transplantation, 21 cases received immunosuppressive therapy [IST]). Spearman correlation analysis was performed to determine the association between clinical indicators and laboratory test results. The expression of SLAMF6, perforin and granzyme B was also detected in 10 healthy people (normal group) and 13 myelodysplastic syndromes/paroxysmal nocturnal hemoglobinuria (MDS/PNH) patients (MDS/PNH group). Results:(1) At diagnosis: the expression of SLAMF6 was significantly lower in the SAA group than that in the normal group and the MDS/PNH group ([56.40±6.37]% vs [84.34±5.81]% and [82.24±4.98]% (both P<0.001]). The expression of perforin was significantly higher in the SAA group (32.73±8.46) than that in the normal control group (23.75%±5.10%), and the MDS/PNH group (26.12%±5.53%) (both P<0.05). The expression of granzyme B was also significantly higher in the SAA group (36.23%±7.94%) than that in the normal control group (21.67%±5.05%) and the MDS/PNH group (21.79%±5.10%) (both P<0.001). The expression of SLAMF6 was positively correlated with the hemoglobin ( r=0.804), and reticulocyte absolute values ( r=0.656) in peripheral blood, percentage of granulocytes ( r=0.643) and erythrocytes ( r=0.622) in bone marrow of SAA patients (all P<0.05). Expression of SLAMF6 was negatively correlated with perforin ( r=-0.792) and granzyme B ( r=-0.908) on CD8 +T cells in patients with SAA (both P<0.001). (2) After treatment: the expression of SLAMF6 in peripheral blood CD8 +T cells of 30 surviving patients was higher than pre-treatment ([79.19±12.69]% vs [56.40±6.37]%, P<0.001). The expressions of perforin and granzyme B were lower than pre-treatment level (both P<0.05). The expression of SLAMF6 on CD8 +T cells in 11 transplanted patients was higher than before transplantation ([86.54±3.75]% vs [56.40±7.35]%, P<0.001). The expressions of perforin and granzyme B were lower than before transplantation (both P<0.05). The expression of SLAMF6 on CD8 +T cells in 12 IST-respond patients was higher than that before treatment, while the perforin and granzyme B levels were lower than pre-treatment (all P<0.05). The post-treatment expressions of SLAMF6, perforin and granzyme B were similar as before treatment levels in 7 IST-unrespond patients (all P>0.05). Conclusion:SLAMF6 is significantly down-regulated on CD8 +T cells in newly diagnosed SAA, negatively correlated with the effective factors of CD8 +T cells, which might participate in the immune regulatory of CD8 +T cells as a negative regulatory factor in patients with SAA. The SLAMF6 is significantly up-regulated after hematopoietic recovery, while there is no significant change in treatment-unrespond patients, which could thus serve as an useful diagnostic and therapeutic index of patients with SAA.

ABSTRACT

Objective:To explore and compare the value of radiomic features based on 18F-fluorodeoxyglucose (FDG) PET and CT in distinguishing epidermal growth factor receptor (EGFR) mutation status in patients with lung adenocarcinoma. Methods:Pretreatment 18F-FDG PET/CT images and EGFR gene status of 114 patients (64 males and 50 females, aged range: 35-84 (average age: 61) years) with primary lung adenocarcinoma between January 2017 and December 2017 were retrospectively collected. The volume of interest was drawn manually slice by slice, then the features were extracted by the LIFEx software. The parameters were screened by least absolute shrinkage and selection operator (LASSO) method for 200 times, and ten-fold cross-validation was used to select the best tuning parameter λ. Three models, namely M PET, M CT, M PET+ CT, were constructed by binary logistic stepwise regression. The receiver operating characteristic (ROC) curve was generated and the corresponding area under the curve (AUC), sensitivity, specificity and accuracy were calculated. The AUCs of three models were compared by Delong test. Results:Totally, 53.51%(61/114) patients were with wild type EGFR and 46.49%(53/114) patients had EGFR mutation. There were 3, 3, 7 parameters selected to form M PET, M CT, M PET+ CT, respectively. The AUCs for M PET, M CT, M PET+ CT were 0.730, 0.752 and 0.866 respectively. When the cut-off values were 0.427, 0.522, 0.378 for M PET, M CT and M PET+ CT, the Youden index were up to the maximum as 0.420, 0.405, 0.630, with sensitivities of 83.0%(44/53), 58.5%(31/53), 92.5%(49/53), specificities of 59.0%(36/61), 82.0%(50/61), 70.5%(43/61) and accuracies of 70.2%(80/114), 71.1%(81/114), 80.7%(92/114), respectively. There was no significant difference between AUC of M PET and M CT ( z=-0.320, P>0.05). The differences of AUCs between M PET+ CT and M PET, M PET+ CT and M CT were statistically significant ( z values: 2.963, 2.523, both P<0.05). Conclusions:PET, CT and PET+ CT radiomic features are all associated with EGFR gene expression in lung adenocarcinoma. M PET+ CT has the highest predictive efficiency.
