ABSTRACT

Objective:To analyze the effects of different blood pressure variables and their variabilities on diabetic nephropathy(DN)in patients with type 2 diabetes.Methods:This prospective cohort study included 3 050 type 2 diabetic patients without DN at baseline from Lee′s clinic in Taiwan, China. The metabolic parameters of patients were regularly checked, and urine albumin creatinine ratio(UACR)were evaluated annually. The average follow-up period was 7 years(3-10 years). The means and standard deviations(SD)of systolic blood pressure(SBP), diastolic blood pressure(DBP), pulse pressure(PP), and mean arterial pressure(MAP)were calculated. According to whether SBP-Mean was higher or lower than 130 mmHg(1 mmHg=0.133 kPa) and SBP-SD was higher or lower than 11.06 mmHg(average SBP-SD), these patients were divided into four groups: Q1(SBP-Mean<130 mmHg, SBP-SD<11.06 mmHg); Q2(SBP-Mean<130 mmHg, SBP-SD≥11.06 mmHg); Q3(SBP-Mean≥130 mmHg, SBP-SD<11.06 mmHg); Q4(SBP-Mean≥130 mmHg, SBP-SD≥11.06 mmHg). In the same way, according to whether PP-Mean was higher or lower than 80 mmHg(average PP-Mean)and PP-SD was higher or lower than 6.48 mmHg(average PP-SD), the patients were divided into Q1-Q4 groups.Results:After adjusting age, sex, and diabetes duration, Cox regression analysis showed that SBP-Mean, SBP-SD, PP-Mean, and PP-SD were the risk factors of DN. After the stratification according to SBP-Mean and SBP-SD, the patients in Q4 group( HR=1.976, P<0.001)had the highest risk while those in Q1 group displayed the lowest risk for DN. Additionally, the patients in Q3 group( HR=1.614, P<0.001)imposed a higher risk than that in Q2 group( HR=1.408, P<0.001). By stratificating the patients based on PP-Mean and PP-SD, the patients in Q4 group revealed the highest risk of DN( HR=1.370, P<0.001)while those in Q1 group had the lowest risk. In addition, the patients in Q3 group( HR=1.266, P<0.001)had a higher risk of DN compared with those in Q2 group( HR=1.212, P<0.001). Conclusion:SBP and PP variabilities are the predictors of DN in patients with type 2 diabetes.

ABSTRACT

Objective:To explore the impacts of postoperative radiotherapy on long-term survival of the patients with resectable locally advanced (T 3-4and/or N +) biliary tract cancers (BTCs) and to analyze the prognostic factors. Methods:The patients with locally advanced gallbladder cancer ( n=1 922) and the patients with extrahepatic biliary duct cancer ( n=3 408) who received surgical resection during 2006-2016 were selected from the Surveillance, Epidemiology, and End Result (SEER) database. They were grouped according to different treatment schemes (only surgery and surgery + radiation). The propensity score matching (PSM) method was employed to adjust the differences in baseline prognostic characteristics between patients who received only surgery and those treated with surgery+ radiation. The role of the two treatment schemes on the survival of the patients was analyzed using the Kaplan-Meier method and the prognosis factors were assessed using the Cox regression. Results:The 1 174 patients with gallbladder cancers and the 2 144 patients with extrahepatic biliary duct cancer were respectively matched according to propensity scores. The postoperative radiotherapy showed a significant advantage in 5-year cancer-specific survival (CSS) compared to only surgery for both the patients with gallbladder cancer ( χ2=35.73, P< 0.001) and those with extrahepatic biliary duct cancer ( χ2=9.878, P=0.002). After adjusting related covariates, independent prognostic factors for all the patients included pathological grading, T status, N status, treatment pattern, and age. For the patients with extrahepatic biliary duct cancer, independent prognostic factors also included race and year of diagnosis. The benefits of postoperative radiotherapy were observed in various clinicopathologic characteristics except for the patients with T 1-2 gallbladder cancer and the extrahepatic biliary duct cancer patients with a pathological grade of Ⅰ-Ⅱ and N 0 status or with age ≥ 70. Conclusions:Long-term survival benefits can be gained through postoperative radiotherapy for the patients with resectable locally advanced (T 3-4 and/or N+ ) BTCs. However, adjuvant radiation should be cautiously adopted for the patients with T 1-2 gallbladder cancer and the extrahepatic biliary duct cancer patients with a pathological grade of I-Ⅱ and N 0 status or with age ≥70.

ABSTRACT

Objective:To explore the active components, targets, and signaling pathways responsible for Bushen Zhuyun prescription in treating the recurrent spontaneous abortion (RSA) based on network pharmacology and uncover its potential mechanism by molecular docking and in vitro cell experiments. Method:The active components of Bushen Zhuyun prescription were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Integrated Database (TCMID) and the published articles, followed by the prediction of drug action targets based on such platforms as DrugBank and SwissTargetPrediction. GeneCards and Online Mendelian Inheritance in Man (OMIM) were searched to obtain the RSA targets, which were then intersected with the targets of Bushen Zhuyun Decoction. Following the plotting of Bushen Zhuyun prescription-compound-target-RSA network by Cytoscape 3.7.1, the protein-protein interaction (PPI) network was then constructed with STRING for screening the core network. The resulting common targets were then subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis using R software. Autodock Vina 1.1.2 was used for molecular docking. The activation of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway by Bushen Zhuyun prescription was verified in human umbilical vein endothelial cells (HUVEC) <italic>in vitro</italic>. Result:It was found that 49 potential active components of Bushen Zhuyun prescription might act on 133 RSA targets. GO enrichment analysis yielded 470 biological processes, with angiogenesis, vascular development, cellular proliferation, and oxidative activity mainly involved. KEGG enrichment analysis revealed 103 signaling pathways (<italic>P</italic><0.05), and the PI3K/AKT signaling pathway, advanced glycation end product (AGE)/receptor for advanced glycation end product (RAGE) signaling pathway, and tumor necrosis factor (TNF) signaling pathway were the main ones. As indicated by molecular docking, the Vina scores of the main active component kaempferol with AKT1 and vascular endothelial growth factor A (VEGFA) were the lowest and similar. It was confirmed <italic>in vitro</italic> cell experiments that Bushen Zhuyun prescription activated the PI3K/AKT signaling pathway and up-regulated the expression of VEGFA and downstream AKT protein to promote angiogenesis. Conclusion:Bushen Zhuyun prescription promotes angiogenesis at the maternal-fetal interface by regulating angiogenesis and cellular proliferation, activating the PI3K/AKT pathway, and up-regulated the VEGFA expression, which is beneficial to the formation of placenta in early pregnancy and the maintenance of early pregnancy. This study has provided ideas for new drug development.

ABSTRACT

Background@#Continuous peripheral nerve blocks (CPNBs) have been investigated to control pain for abdominal surgery via midline laparotomy while avoiding the adverse events of opioid or epidural analgesia. The review compiles the evidence comparing CPNBs to multimodal and epidural analgesia. @*Methods@#We conducted a systematic review using broad search terms in MEDLINE, EMBASE, Cochrane. Primary outcomes were pain scores and cumulative opioid consumption at 48 hours. Secondary outcomes were length of stay and postoperative nausea and vomiting (PONV). We rated the quality of the evidence using Cochrane and GRADE recommendations. The results were synthesized by meta-analysis using Revman. @*Results@#Our final selection included 26 studies (1,646 patients). There was no statistically significant difference in pain control comparing CPNBs to either multimodal or epidural analgesia (low quality evidence). Less opioids were consumed when receiving epidural analgesia than CPNBs (mean difference [MD]: –16.13, 95% CI [–32.36, 0.10]), low quality evidence) and less when receiving CPNBs than multimodal analgesia (MD: –31.52, 95% CI [–42.81, –20.22], low quality evidence). The length of hospital stay was shorter when receiving epidural analgesia than CPNBs (MD: -0.78 days, 95% CI [-1.29, -0.27], low quality evidence) and shorter when receiving CPNBs than multimodal analgesia (MD: -1.41 days, 95% CI [-2.45, -0.36], low quality evidence). There was no statistically significant difference in PONV comparing CPNBs to multimodal (high quality evidence) or epidural analgesia (moderate quality evidence). @*Conclusion@#CPNBs should be considered a viable alternative to epidural analgesia when contraindications to epidural placement exist for patients undergoing midline laparotomies.

ABSTRACT

BACKGROUND@#More and more scholars have called for the cumulative live birth rate (CLBR) of a complete ovarian stimulation cycle as a key indicator for assisted reproductive technology. This research aims to study the CLBR of the first ovarian hyperstimulation cycles and analyze the related prognosis factors that might affect the CLBR.@*METHODS@#Our retrospective study included first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) cycles performed between January 2013 to December 2014. A total of 17,978 couples of first ovarian hyperstimulation IVF/ICSI cycles were included. The study was followed up for 4 years to observe the CLBR. The multivariable logistic regression model was used to analyze the prognosis factor, P value of <0.05 was considered statistically significant.@*RESULTS@#The cumulative pregnancy rate was 58.14% (10,452/17,978), and the CLBR was 49.66% (8928/17,978). The female age was younger in the live birth group when compared with the non-live birth group (30.81 ± 4.05 vs. 33.09 ± 5.13, P < 0.001). The average duration of infertility was shorter than the non-live birth cohort (4.22 ± 3.11 vs. 5.06 ± 4.08, P < 0.001). The preliminary gonadotropin used and the total number of gonadotropin used were lower in the live birth group when compared with the non-live birth group (both P < 0.001). Meanwhile, the number of oocytes retrieved and transferrable embryos were both significantly higher in the live birth group (15.35 ± 7.98 vs. 11.35 ± 7.60, P < 0.001; 6.66 ± 5.19 vs. 3.62 ± 3.51, P < 0.001, respectively).@*CONCLUSIONS@#The women's age, body mass index, duration of infertility years, infertility factors, controlled ovarian hyperstimulation protocol, the number of acquired oocytes, and number of transferrable embryos are the prognosis factors that significantly affected the CLBR.

ABSTRACT

Objective To investigate the change of biological characteristics after stable knockdown of the coding gene of 3-methylcrotonyl-coenzyme A carboxylase β subunit (MCCC2) expression in DU145 by lentivirus shRNA. Methods Three groups were included in this study. shNC was the control group in which MCCC2 was negatively knocked down in DU145. shMCCC2 was the experimental group in which MCCC2 was knocked down. DU145 was the blank group without any treatment. The expression of MCCC2 was assessed by Western blot and qPCR. The proliferation of DU145 cells was detected by CCK8 assay. The migration ability of DU145 was detected by transwell. The apoptosis of DU145 cells was detected by flow cytometry. Results The expression level of MCCC2 in shMCCC2 group was significantly lower than that in shNC group (0.22 ± 0.02 vs 0.61 ± 0.06, P < 0.001). The proliferation (2.24 ± 0.04 vs 3.13 ± 0.15) and migration (23.96 ± 1.85 vs 49.73 ± 0.63) of DU145 cells in shMCCC2 group was significantly lower than that in shNC group, whereas the apoptosis (12.64 ± 0.30 vs 3.68 ± 0.02) of DU145 cells in shMCCC2 was significantly higher than that in shNC group. Conclusion MCCC2 knockdown significantly inhibited the proliferation and migration, and induced apoptosis of DU145 cells, which indicated that the down-regulation of MCCC2 is correlated with the change of tumor biological characteristics of DU145 cell line and can be a potential target for the treatment of prostate cancer.

ABSTRACT

Objective:To investigate the pathogenic gene locus and prenatal genetic diagnosis of 54 families with oculocutaneous albinism (OCA).Methods:This retrospective study enrolled 54 OCA probands and their families from Gansu Province Maternal and Child Health Care Hospital from May 2014 to May 2020. TYR gene variation screening was performed on the probands by Sanger sequencing. Those with negative results were analyzed by high-throughput sequencing, and further verification was performed on their parents by Sanger sequencing. Among the 54 families, 15 ml amniotic fluid were collected from 16 women at 18-21 gestational weeks in their subsequent pregnancy. Sanger sequencing combined with short tandem repeats sequence for linkage analysis were performed for genetic analysis. All data were analyzed using descriptive statistical analysis. Results:Out of the 54 OCA probands, 48 were diagnosed as OCA1, five were OCA2 and one was OCA4 based on the Sanger sequencing and high-throughput sequencing detection. A total of 26 different variation sites were involved in the 48 OCA1 probands, including 15 missense mutations, five nonsense mutations, three splicing mutations, and three frame-shift mutations, among which, c.929insC (29%, 28/96) was the most frequent mutation, followed by c.896G>A (11%, 11/96), c.832C>T (8%, 8/96) and c.703T>C (5%, 5/96). The diagnosis was confirmed in all 16 fetuses in the 16 families that underwent prenatal diagnosis. Five of them were affected and their mothers chose to terminate the pregnancies, the other 11 pregnancies continued to delivery, including seven heterozygous carriers and four fetuses without the same pathogenic allele as the proband. Maternal contamination was excluded in all prenatal samples using short tandem repeat for linkage analysis. All 11 children were in good health during telephone follow-up one month after birth. Postnatal validations were consistent with the prenatal tests.Conclusions:Genetic diagnosis could accurately identify various types of OCA and help to provide prenatal diagnosis and fertility consultation for subsequent pregnancies.

ABSTRACT

Objective:To evaluate the status quo and influencing factors of hyperlipidemia management in patients with contracted family doctor service in the community.Method:The baseline data and blood lipid testing results of 752 hyperlipidemia patients (334 males and 418 females) with contracted family doctor service in Yuetan Community Health Service Center from November?2019 to May 2020 were collected. The hyperlipidemic patients were managed by family doctors based on atherosclerotic cardiovascular diseases(ASCVD) riks assessment. The ASCVD risk levels and low-density lipoprotein cholesterol (LDL-C) compliance rate of patients with different general data were compared, and the influencing factors of LDL-C control failure were analyzed by logistic regression.Results:The ASCVD risk assessment showed that among 752 patients there were 172 cases of low risk(22.87%), 167 cases of moderate risk(22.21%),352 cases of high risk(46.81%) and 61 cases of extremely high risk(8.11%). A significant difference was detected in sex,rate of smoking,incidence of overweight or obesity among patients with different ASCVD risk levels ( P<0.05).The overall control rate of LDL-C was 48.8% (367/752), that for low, moderate, high and extremely high risk patients were 83.73% (144/172), 53.89% (90/167), 34.38% (121/352) and 19.67%(12/61), respectively. A significant difference was detected in sex(female: 52.87%, 221/418),age(aged over 80: 58.82%, 110/187), rate of smoking (non-smoking:52.40%, 327/624) and medication compliance (good compliance:52.87%,221/418) between LDL-C control and uncontrol groups (χ2=6.323,11.816,19.022,25.274; P<0.05). Multiple logistic regression analysis revealed that male gender ( OR=1.800,95% CI:1.325-2.419), smoking ( OR=2.630,95% CI:1.726-4.007) and poor medication compliance ( OR= 2.179, 95% CI: 1.581-3.003) were independent risk factors for uncontrolled LDL-C levels. Conclusion:Patients with hyperlipidemia have a relatively high risk of cardiovascular diseases, and their blood lipids are not well controlled. The management of blood lipid should be enhanced in patients with chronic diseases, particularly for male patients with smoking and poor medication compliance.

ABSTRACT

Hyperuricemia is not only the biochemical basis of gout, but also closely related to the development of metabolic syndrome, cardiovascular diseases, chronic kidney disease, etc. Xanthine oxidase (XOD) is the key catalytic enzyme for uric acid biosynthesis, therefore the vital target for anti-hyperuricemic drugs. In this study, compound CC18022 was designed and synthesized specifically targeting to XOD. Molecular docking analysis indicated a fairly tight binding between CC18022 and XOD. In the in vitro study, CC18022 significantly inhibited XOD activity with a half maximal inhibitory concentration (IC50) value in the order of nmol·L-1, which is relative to the XOD inhibitor febuxostat. By using both acute and chronic hyperuricemic mice model, compound CC18022 was found to have serum uric acid-lowering effect in a dose-dependent manner in vivo. The animal welfare and experimental processes were in accordance with the provisions of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences. In the acute hyperuricemic mice, CC18022 significantly inhibited serum XOD activity, and also the XOD activity in intestine and liver, which were related to purine absorption and metabolism. Therefore, the novel compound CC18022 exhibited significant inhibition on XOD activity and anti-hyperuricemic effects, making it a favorable candidate for further research.

ABSTRACT

OBJECTIVE@#To detect fusion gene with pathological significance in a patient with refractory and relapsed acute B cell lymphoblastic leukemia (B-ALL) and to explore its laboratory and clinical characteristics.@*METHODS@#Transcriptome sequencing was used to detect potential fusion transcripts. Other laboratory results and clinical data of the patient were also analyzed.@*RESULTS@#The patient was found to harbor TCF3 exon 17-ZNF384 exon 7 in-frame fusion transcript. The minimal residual disease (MRD) has remained positive after multiple chemotherapy protocols including CD19-, CD22- targeted chimeric antigen receptor T cells immunotherapy. The patient eventually achieved complete remission and sustained MRD negativity after allogeneic hemopoietic stem cell transplantation (allo-HSCT).@*CONCLUSION@#Transcriptome sequencing can effectively detect potential fusion genes with clinical significance in leukemia. TCF3-ZNF384 positive B-ALL has unique laboratory and clinical characteristics, may not well respond to chemotherapy and immunotherapy, and is more likely to relapse. Timely allo-HSCT treatment may help such patients to achieve long-term disease-free survival. TCF3-ZNF384 positive B-ALL is not uncommon in pediatric patients but has not been effectively identified.

ABSTRACT

OBJECTIVE@#To study the epidemiologic characteristics of human herpes virus (HHV) activated infection in the diseases of blood system and patients received allo-HSCT by statistically analyzing the screening results of 8 human herpes viruses (HHVs) of 4164 patients in Hebei Yanda LU Dao-Pei Hospital from 2012 to 2017.@*METHODS@#PCR was used to screen 8 HHVs.@*RESULTS@#Two thousand and fifty-two patients (49.28%) were HHV-positive among 4164 patients screened. Among these patients screened, the infection spectra of 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation of totally 2994 patients were summarized as follows: the positive rate of EBV (29.49%) was the highest, that of HCMV (23.15%), HHV-6 was 18.77% and HHV-7 was 17.64%, while the remaining 4 HHVs all≤2.1%. The rate of co-infection of various HHVs was significantly higher than that of single infection of HHV among all these disease groups except familial hemophagocytic lymphohistiocytosis, for which single EBV infection was the most common. The differences of positive rates among these 8 human HHVs in hematological diseases as well as patients received allogeneic hematopoietic stem cell transplantation were statistically significant by Chi-square test of R*C tables (χ=54.99, P<0.05). For each HHV, the differences of positive rates among the above-mentioned disease groups were also statistically significant except HHV-8 (P<0.05).@*CONCLUSION@#The patients with various blood diseases have different activated infection spectra of HHVs. EBV, HCMV, HHV-6 and HHV-7 are most common in HHVs infection. Different HHVs infections correlate with different hematologion diseases.

ABSTRACT

Background@#Intraprocedural rupture (IPR) is a devastating complication in endovascular treatment of ruptured intracranial aneurysms, but its risk factors have not been fully assessed. This study was performed to explore the risk factors for IPR during embolization of ruptured cerebral aneurysms. @*Methods@#A total of 1,494 patients with ruptured intracranial aneurysms who underwent endovascular interventional embolization were enrolled. Clinical characteristics were collected for each patient. Univariate and multivariate logistic regression analysis was employed to identify the factors independently associated with IPR. A receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff values of continuous variables predicting IPR. @*Results@#Forty-one patients suffered from IPR (2.7%). Multivariate logistic regression analysis indicated that aneurysm size (odds ratio [OR], 0.819; 95% confidence interval [CI], 0.732–0.916), aneurysms with irregular morphology (OR, 2.162; 95% CI, 1.143–4.091), time from symptom onset to intervention (OR, 1.615; 95% CI, 1.207–2.161), and vasospasm during embolization (OR, 2.021; 95% CI, 1.038–3.934) were the independent risk factors of IPR. ROC curve analysis showed that the area under the curve for aneurysm size and time from onset to intervention were 0.697 (cutoff value, 3.4 mm; sensitivity, 78.8%; and specificity, 53.7%) and 0.659 (cutoff value, 2 days; sensitivity, 78.0%; and specificity, 45.2%), respectively. @*Conclusion@#Aneurysms with irregular morphology, aneurysms ≤ 3.4 mm in diameter, time from onset to intervention > 2 days and cerebral vasospasm during embolization are independent risk factors for IPR during coil embolization of ruptured aneurysms.

ABSTRACT

Background@#Intraprocedural rupture (IPR) is a devastating complication in endovascular treatment of ruptured intracranial aneurysms, but its risk factors have not been fully assessed. This study was performed to explore the risk factors for IPR during embolization of ruptured cerebral aneurysms. @*Methods@#A total of 1,494 patients with ruptured intracranial aneurysms who underwent endovascular interventional embolization were enrolled. Clinical characteristics were collected for each patient. Univariate and multivariate logistic regression analysis was employed to identify the factors independently associated with IPR. A receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff values of continuous variables predicting IPR. @*Results@#Forty-one patients suffered from IPR (2.7%). Multivariate logistic regression analysis indicated that aneurysm size (odds ratio [OR], 0.819; 95% confidence interval [CI], 0.732–0.916), aneurysms with irregular morphology (OR, 2.162; 95% CI, 1.143–4.091), time from symptom onset to intervention (OR, 1.615; 95% CI, 1.207–2.161), and vasospasm during embolization (OR, 2.021; 95% CI, 1.038–3.934) were the independent risk factors of IPR. ROC curve analysis showed that the area under the curve for aneurysm size and time from onset to intervention were 0.697 (cutoff value, 3.4 mm; sensitivity, 78.8%; and specificity, 53.7%) and 0.659 (cutoff value, 2 days; sensitivity, 78.0%; and specificity, 45.2%), respectively. @*Conclusion@#Aneurysms with irregular morphology, aneurysms ≤ 3.4 mm in diameter, time from onset to intervention > 2 days and cerebral vasospasm during embolization are independent risk factors for IPR during coil embolization of ruptured aneurysms. More attention should be paid to the factors increasing the risk of IPR in patients with ruptured aneurysms so as to minimize this complication.
