ABSTRACT

Objective:To explore the clinical effect of simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab in the treatment of advanced nasopharyngeal carcinoma.Methods:A total of 64 patients with advanced nasopharyngeal carcinoma who were admitted to Kaiping Central Hospital of Guangdong Province from June 2017 to January 2019 were selected and divided into the observation group and control group according to the random number table method, with 32 cases in each group. Both groups were given chemotherapy and nimotuzumab on the basis of radiotherapy. The observation group received simultaneous whole-course hyperfractionated intensity-modulated radiation therapy, and the control group received conventional fractionated intensity-modulated radiation therapy. The short-term efficacy, Karnofsky score, overall survival rate, progression-free survival rate, acute radiation reaction, and late radiation injury in the two groups were observed.Results:Six months after radiotherapy, the efficient rate of the observation group was higher than that of the control group [96.9% (31/32) vs. 75.0% (24/32), χ2 = 6.335, P < 0.05]. At the end of radiotherapy and 3 months after the end of radiotherapy, the Karnofsky scores of the observation group were higher than those of the control group, and the differences were statistically significant [(75±3) points vs. (71±3) points, t = 5.891, P < 0.05; (80±4) points vs.(77±4) points, t = 3.201, P = 0.002]. All patients were well tolerated, no grade 4 acute radiation reaction was observed, and radiotherapy was completed as planned. The incidence rate of oral mucosal reaction in the observation group was lower than that in the control group [21.9% (7/32) vs. 50.0% (16/32), χ2 = 5.497, P < 0.05]. The incidence rates of severe dry mouth and neck soft tissue fibrosis in the observation group were lower than those in the control group [6.2% (2/32) vs. 28.1% (9/32), χ2 = 5.379, P = 0.043; 3.1% (1/32) vs. 21.9% (7/32), χ2 = 5.143, P < 0.05]. The follow-up time was 14-20 months, and the median follow-up time was 17 months. There was no statistical difference in overall survival time between the two groups ( χ2 = 0.553, P = 0.557). The progression-free survival time of the observation group was better than that of the control group ( χ2 = 3.954, P = 0.044). Conclusion:The simultaneous whole-course hyperfractionated intensity-modulated radiation therapy combined with chemotherapy and nimotuzumab are effective in the treatment of advanced nasopharyngeal carcinoma, and the adverse reactions can be tolerated.

ABSTRACT

Objective:To explore the efficacy of nimodipine combined with ganglioside in the treatment of cerebral hemorrhage and its effect on the expression of serum resistin and oxidized low-density lipoprotein (ox-LDL).Methods:According to the random number table method, 100 patients with cerebral hemorrhage admitted in Central Hospital of Zibo from February 2018 to February 2020 were divided into the single treatment group and the combined treatment group, with 50 cases in each group. In addition to conventional treatment, the single treatment group was additionally treated with nimodipine, and the combined group was additionally treated with nimodipine combined with ganglioside. After 2 weeks of intervention, the efficacy of the two groups was evaluated, and the National Institutes of Health Stroke Scale (NIHSS) scores, Ability of Daily Living (ADL) scores, serum inflammatory factors, resistin and ox-LDL levels were evaluated and recorded between the two groups before and after treatment.Results:The total effective rate of treatment in the combined treatment group was higher than that in the single treatment group: 90.0%(45/50) vs. 74.0%(37/50), and the difference was statistically difference ( P<0.05). After 2 weeks′ treatment, the scores of NIHSS was decreased and the scores of ADL was increased in two groups, and the scores of NIHSS in combined treatment group was lower than that in the single treatment group: (9.41 ± 1.27) scores vs. (12.10 ± 1.65) scores; the scores of ADL in the combined treatment group was higher than that in the single treatment group: (67.82 ± 9.04) scores vs. (59.10 ± 8.75) scores, and the differences were statistically differences ( P<0.05). After 2 weeks′ treatment, the levels of serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), resistin and ox-LDL in the two groups were decreased, and the levels of above index in the combined treatment group were lower than those in the single treatment group: (4.81 ± 1.03) mg/L vs. (6.10 ± 1.73) mg/L, (40.96 ± 9.21) μg/L vs. (56.74 ± 8.93) μg/L, (33.20 ± 7.96) μg/L vs. (44.76 ± 8.43) μg/L, (0.29 ± 0.09) μg/L vs. (0.45 ± 0.13) μg/L, (336.25 ± 69.74) mg/L vs. (372.18 ± 68.52) mg/L, and the differences were statistically differences ( P<0.05). There was no significant difference in adverse reactions between the two groups ( P<0.05). Conclusions:Nimodipine combined with ganglioside has a clear efficacy in the treatment of cerebral hemorrhage. It can effectively inhibit inflammation indicators, reduce serum resistin and ox-LDL levels, promote the recovery of nerve defects, and improve their living ability.

ABSTRACT

OBJECTIVE: To explore the protective effect of tea polyphenols and its mechanism in potassium dichromate(PD)-induced acute renal injury in mice. METHODS: The specific pathogen free weaned Kunming mice were divided into control group, model group and low-, middle-and high-dose tea polyphenols groups, with 12 mice in each group. Mice in the control group were given 0.9% sodium chloride solution, and mice in other four groups were given PD solution with 4.275 mg/kg body weight every morning by intragastric administration. Then, mice in the control group and model group were given 0.9% sodium chloride solution in the afternoon, while mice in the low-, middle-and high-dose tea polyphenols groups were given 0.3 mL tea polyphenols solution with a dose of 200, 400 or 600 mg/kg body weight, respectively by gavage, once a day for two consecutive weeks. The body mass of mice was weighed during the experiment. At the end of the experiment, the mice were sacrificed. The kidneys were removed and weighed. The kidney organ coefficients were calculated. The levels of urea nitrogen and creatinine in serum were determined by two-point method, the activities of catalase(CAT) and glutathione peroxidase(GSH-Px) in serum of mice were detected by colorimetry. The pathological change of kidney in mice was observed. RESULTS: The body weight of mice in the model group decreased(P<0.05), while the kidney mass, renal organ coefficient, serum levels of urea nitrogen and creatinine increased(all P<0.05), and the serum activities of CAT and GSH-Px decreased(all P<0.05) compared with the control group. The body weight of mice in the three tea polyphenols groups increased(all P<0.05), while the kidney mass, renal organ coefficient, urea nitrogen and creatinine levels in serum decreased(all P<0.05), and the activities of CAT and GSH-Px in serum increased with the increasing intervention dose of tea polyphenols(all P<0.05) compared with the model group. The change of acute renal injury was mainly caused by renal tubular injury in the model group. The pathological changes of renal tissue in the three tea polyphenols intervention groups were improved compared to that in the model group, and the improvement showed a dose-effect relationship with the intervention of tea polyphenols. CONCLUSION: Tea polyphenols have a protective effect on PD-induced acute renal injury with a dose-effect relationship. Its mechanism of action is related to the fact that tea polyphenols can reduce or reverse oxidative stress and inflammation in the kidney.

ABSTRACT

The present study aimed to determine whether the number of patients with symptomatic benign prostatic hyperplasia (BPH) who preferred surgery decreased during the past 11 years at our center (West China Hospital, Chengdu, China), and whether this change affected the timing of surgery and the physical condition of surgical patients. This retrospective study included 57 557 patients with BPH treated from January 2008 to December 2018. Of these, 5427 patients were treated surgically. Surgical patients were divided into two groups based on the time of treatment (groups 8-13 and groups 13-18). The collected data comprised the percentage of all patients with BPH who underwent surgery, baseline characteristics of surgical patients, rehabilitation time, adverse events, and hospitalization costs. The surgery rates in groups 8-13 and groups 13-18 were 10.5% and 8.5% (P < 0.001), respectively. The two groups did not clinically differ regarding patient age and prostate volume. The rates of acute urinary retention and renal failure decreased from 15.0% to 10.6% (P < 0.001) and from 5.2% to 3.1% (P < 0.001), respectively. In groups 8-13 and groups 13-18, the mean catheterization times were 4.0 ± 1.7 days and 3.3 ± 1.6 days (P < 0.001), respectively, and the mean postoperative hospitalization times were 5.1 ± 2.4 days and 4.2 ± 1.8 days (P < 0.001), respectively. The incidences of unplanned second surgery and death reduced during the study period. The surgery rate decreased over time, which suggests that medication was chosen over surgery. However, the percentage of late complications of BPH also decreased over time, which indicates that the timing of surgery was not delayed.

ABSTRACT

Accumulating evidence supports the significance of aberrant alternative splicing (AS) events in cancer; however, genome-wide profiling of progression-free survival (PFS)-related AS events in testicular germ cell tumors (TGCT) has not been reported. Here, we analyzed high-throughput RNA-sequencing data and percent-spliced-in values for 150 patients with TGCT. Using univariate and multivariate Cox regression analysis and a least absolute shrinkage and selection operator method, we identified the top 15 AS events most closely associated with disease progression. A risk-associated AS score (ASS) for the 15 AS events was calculated for each patient. ASS, pathological stage, and T stage were significantly associated with disease progression by univariate analysis, but only ASS and pathological stage remained significant by multivariate analysis. The ability of these variables to predict 5-year progression was assessed using receiver operating characteristic curve analysis. ASS had stronger predictive value than a combination of age, pathological stage, and T stage (area under the curve = 0.899 and 0.715, respectively). Furthermore, Kaplan-Meier analysis of patients with low and high ASS demonstrated that high ASS was associated with significantly worse PFS than low ASS (P = 1.46 × 10

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

@#Relative/absolute adrenal insufficiency is not uncommmon in the patients undergoing cardiovascular surgery with cardiopulmonary bypass. However, this complication was rarely reported due to its unspecific clinical presentations and the unawareness of ICU physicians and cardiac surgeons. However, this puts them on a higher risk of hemodynamic instability and cardiovascular adverse events during hospitalization. Systematic reviews concentrated on it are rarely reported currently. We aim to review the etiology, risk factors, potential pathogenesis and related research progress for this complication.

ABSTRACT

Obsessive-compulsive disorder (OCD) is a kind of conrmon clinical mental disorder.It has a prolonged course of disease and is difficult to cure.The treatment methods of obsessive-compulsive disorder are mainly composed of drug therapy and psychotherapy, but some patients have poor response to drug therapy.Transcranial magnetic stimulation (TMS) is a non-invasive nerve stimulation technique and is widely used in neuropsychiatric diseases.Transcranial magnetic stimulation is gradually increasing in the treatment of obsessive-compulsive disorder.To date, researches at home and abroad have reported that transcranial magnetic stimulation can improve the symptoms of obsessive-compulsive disorder and help to improve its cognitive function.However, the clinical therapeutic effects reported are inconsistent due to different stimulation sites, stimulation parameters, sample size and stimulation time.Especially in recent years, transcranial magnetic stimulation research on obsessive-compulsive disorder has made further exploration in target selection, stimulation sequence, stimulation mode and so on.This paper focuses on the clinical effects of different stimulation sites on the treatment of OCD, and provids new ideas for further intervention and treatment of OCD.

ABSTRACT

Objective:To investigate the ultrastructural and biomechanical properties of the internal limiting membrane (ILM) in high myopic macular hole (HM-MH) eyes.Methods:ILM specimens were peeled from 14 eyes with HM-MH from August to December in 2017, and 16 eyes with idiopathic macular hole (IMH) in the same period were served as a control.Specimens were detected by immunefluorescence, transmission electron microscopy (TEM) and atomic force microscopy (AFM). This study followed the Declaration of Helsinki, and was approved by the Ethics Committee of Zhongshan Ophthalmic Center.Results:The immunofluorescence staining results showed that collagen Ⅳ was mainly distributed on the vitreal side and laminin on the retinal side of ILM in both groups.TEM findings revealed that the thickness of ILMs in the HM-MH group was (1.01±0.17)μm, which was significantly decreased compared with (1.92±0.21)μm in the IMH group ( t=12.880, P<0.001). The stiffness of the ILMs in the HM-MH group was (2.86±0.33)MPa, which was significantly higher than (0.88±0.23)MPa in the IMH group ( t=-12.650, P<0.001). The stiffness of the ILMs in the HM-MH group was positively correlated with the axial length ( r=0.832, P<0.001). Conclusions:Compared with IMH, the thickness of ILMs from HM-MH patients is thinner and the stiffness is higher, which contribute to a deep understanding of the pathogenesis of HM-MH.

ABSTRACT

OBJECTIVE@#To investigate the ameliorate effect and underlying mechanism of Xueshuantong for Injection (Lyophilized, , XST) in streptozocin (STZ)-induced diabetic retinopathy (DR) rats.@*METHODS@#Diabetes mellitus (DM) model was induced by intraperitoneal (i.p.) injection of STZ (60 mg/kg) in Sprague-Dawley rats. Diabetic rats were randomized into 3 groups (n=10) according to a random number table, including DM, XST50 and XST100 groups. XST treatment groups were daily i.p. injected with 50 or 100 mg/kg XST for 60 days, respectively. The control and DM groups were given i.p. injection with saline. Blood glucose level and body weight were recorded every week. Histological changes in the retina tissues were observed with hematoxylin-eosin staining. Apoptosis and inflammation related factors, including cleaved caspase-3, glial fifibrillary acidic protein (GFAP), tumor necrosis factor-α (TNF-α) and intercellular cell adhesion molecule-1 (ICAM-1) were detected by Western blot or real-time polymerase chain reaction. Then, the levels of advanced glycation end product (AGE) and its receptor (RAGE) were investigated. Tight junctions proteins (Zonula occludens-1 (ZO-1), Occludin and Claudin-5) of blood-retinal barrier were detected by Western blot. The levels of retinal fifibrosis, transforming growth factor-β1 (TGF-β1)-Smad2/3 signaling pathway were evaluated at last.@*RESULTS@#There was no signifificant difference in the body weight and blood glucose level between XST and DM groups (P>0.05). Compared with the DM group, XST treatment signifificantly increased the retinal thickness of rats (P<0.05 or P<0.01), and suppressed cleaved caspase-3 expression (P<0.01). XST increased the protein expressions of ZO-1, Occludin and Claudin-5 and decreased the mRNA expressions of matrix metalloproteinase 2 (MMP-2) and MMP-9 (P<0.05 or P<0.01). Moreover, XST signifificantly reduced the productions of AGE and RAGE proteins in the retina of rats (P<0.05 or P<0.01), suppressed the over-expression of TNF-α, and decreased the elevated level of ICAM-1 in retina of rats (P<0.05 or P<0.01). XST signifificantly reduced the levels of α-smooth muscle actin (α-SMA), connective tissue growth factor (CTGF), TGF-β1 and phosphorylation of Smad2/3 protein in rats (P<0.05 or P<0.01).@*CONCLUSIONS@#XST had protective effects on DR with possible mechanisms of inhibiting the inflammation and apoptosis, up-regulating the expression of tight junction proteins, suppressing the productions of AGE and RAGE proteins, and blocking the TGF-β/Smad2/3 signaling pathway. XST treatment might play a role for the future therapeutic strategy against DR.

ABSTRACT

To explore the mechanism of Sijunzi Decoction in the treatment of ulcerative colitis(UC) based on network pharmacology. The active components and corresponding targets of Sijunzi Decoction were extracted with Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets were standardized with the help of Uniprot database. The related targets of UC were obtained through GeneCards database and Disgenet database, and the intersection targets of drugs and diseases were screened by R language. The visual regulation network of "active ingredient-disease target" of Sijunzi Decoction was constructed by Cytoscape software, and the protein-protein interaction network was constructed by STRING database. The functional enrichment analysis of gene ontology(GO) and the enrichment analysis of Kyoto encyclopedia of genes and genomes(KEGG) pathway were carried out on Bioconductor platform, and some of the targets were verified by animal experiments. Through database analysis, a total of 135 active components of Sijunzi Decoction, 114 predicted targets and 80 common targets with UC were obtained. The core target proteins included interleukin 6(IL-6), caspase-3(CASP3), vascular endothelial growth factor A(VEGFA), epidermal growth factor receptor(EGFR) and so on. GO functional enrichment analysis involved 102 items, which mainly affected transcription factor activity, enzyme activity, receptor activity and biochemical process regulation. KEGG pathway enrichment analysis showed that 120 items were involved in human cytomegalovirus infection, cancer, apoptosis, inflammation and other pathways. Mouse experiments showed that Sijunzi Decoction could down-regulate the expression of target proteins IL-6 and caspase-3 and inhibit intestinal epithelial cell apoptosis. The treatment of UC with Sijunzi Decoction is the result of the interaction among multi-components, multi-targets and multi-pathways. It is proved by experiments that Sijunzi Decoction may play an effective role by regulating the expression of IL-6 and caspase-3, and getting involved in apoptosis, inflammation and other pathways.

ABSTRACT

The mitogen-activated protein kinase (MAPK) signaling pathway is a highly conserved signal transduction pathway from yeast to human species, and is widely distributed in various eukaryotic cells. In almost all of the species studied over the past three decades, this signaling pathway plays a crucial role in the development of female germ cells and meiotic maturation. Especially in a variety of mammalian species including primates, rodents, and domestic animals, the MAPK signaling pathway is activated during the resumption of first oocyte meiosis and plays an indispensable role in meiotic spindle assembly and cell cycle progression. In granulosa cells of fully grown ovarian follicles, the MAPK pathway also mediates the physiological action of gonadotropins, including cumulus expansion, ovulation, and corpus luteum formation. Although the MAPK signaling pathway plays a wide range of physiological functions during the female reproduction process, and these functions are highly conserved in evolution, their underlying mechanisms, especially their direct and physiological target molecules, have not been sufficiently studied for a long time. In recent years, based on some new gene-editing mouse models and theoretical findings, as well as the wide application of various omics techniques, it has been further revealed that MAPK directly phosphorylates and activates the RNA binding protein cytoplasmic polyadenylation element-binding protein-1 (CPEB1), promoting poly(A) tail extension of maternal mRNA to regulate protein translation during meiotic recovery. These findings not only constitute the current basic mechanism of mammalian oocyte maturation and ovulation, but also provide useful research ideas for other related research in this field. In this review, we summarize the research findings in our laboratory and from other groups regarding the role of MAPK cascade in regulating oocyte maturation and ovulation. We also discuss the latest research progress on MAPK regulation of mRNA translation and degradation by directly activating the translation initiation complex and mRNA poly(A) polymerase by phosphorylation in the granulosa cells.

ABSTRACT

Pancreatic lipase (PL), a crucial enzyme in the digestive system of mammals, has been proven as a therapeutic target to prevent and treat obesity. The purpose of this study is to evaluate and characterize the PL inhibition activities of the major constituents from Fructus Psoraleae (FP), one of the most frequently used Chinese herbs with lipid-lowering activity. To this end, a total of eleven major constituents isolated from Fructus Psoraleae have been obtained and their inhibition potentials against PL have been assayed by a fluorescence-based assay. Among all tested compounds, isobavachalcone, bavachalcone and corylifol A displayed strong inhibition on PL (IC < 10 μmol·L). Inhibition kinetic analyses demonstrated that isobavachalcone, bavachalcone and corylifol A acted as mixed inhibitors against PL-mediated 4-methylumbelliferyl oleate (4-MUO) hydrolysis, with the K values of 1.61, 3.77 and 10.16 μmol·L, respectively. Furthermore, docking simulations indicated that two chalcones (isobavachalcone and bavachalcone) could interact with the key residues located in the catalytic cavity of PL via hydrogen binding and hydrophobic interactions. Collectively, these finding provided solid evidence to support that Fructus Psoraleae contained bioactive compounds with lipid-lowering effects via targeting PL, and also suggested that the chalcones in Fructus Psoraleae could be used as ideal leading compounds to develop novel PL inhibitors.

ABSTRACT

The data mining technology was used to explore the acupoint selection rules for reflux esophagitis (RE), so as to provide references of clinical acupuncture for RE. The clinical literature of acupuncture for RE published before June 2019 was searched in Chinese journal full-text database (CNKI), SinoMed, Wanfang and VIP databases. The literature was selected according to the inclusion and exclusion criteria and acupoint prescriptions were extracted. The software of IBM SPSS Statistics 23.0 and Clementine 12.0 were used for descriptive analysis and association analysis. A total of 46 articles were selected and 60 acupoint prescriptions were extracted. The descriptive analysis indicated that the top five acupoints used for RE were Zhongwan (CV 12), Zusanli (ST 36), Weishu (BL 21), Neiguan (PC 6) and Gongsun (SP 4). The conception vessel, bladder meridian and stomach meridian were the most commonly selected meridians. In terms of specific acupoints, the crossing points, the front- points and five- points were mainly selected, and the acupoints were mainly distributed in limbs and chest-abdomen. The core acupoint combination for RE was "Zhongwan (CV 12) and Zusanli (ST 36)" and the core prescription was "Zhongwan (CV 12), Zusanli (ST 36), Weishu (BL 21) and Neiguan (PC 6)".
