ABSTRACT

ObjectiveTo explore the effect of external diaphragm pacing therapy combined with abdominal functional electrical stimulation on respiratory function for stroke patients. MethodsFrom October, 2020 to September, 2022, 54 stroke patients were randomly divided into control group (n = 18), external diaphragm pacing group (n = 18) and combined treatment group (n = 18). All the groups received breathing training, while the external diaphragm pacing group received external diaphragm pacing therapy, and the combined treatment group received external diaphragm pacing and abdominal functional electrical stimulation therapy, for two weeks. They were measured forced vital capacity (FVC), forced expiratory volume in first second (FEV1), ratio of forced expiratory volume in first second in forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) with pulmonary function instrument; measured diaphragmatic excursion (DE) and diaphragmatic thickness (DT) with ultrasound, before and after treatment. ResultsThree cases in the control group, two cases in the external diaphragm pacing group and one case in the combined treatment group dropped off. The FVC, FEV1, PEF, MIP, MEP and DE improved in all the groups (|t| > 3.366, P < 0.01) after treatment; and the FVC, FEV1, MIP and DE increased more in the combined treatment group and the external diaphragm pacing group than in the control group (P < 0.05); the FVC and FEV1 increased more in the combined treatment group than in the external diaphragm pacing group (P < 0.05). ConclusionExternal diaphragm pacing therapy may improve ventilation and inspiratory muscle strength, and increase diaphragm movement for stroke patients; while the ventilation improved more after combining with abdominal functional electrical stimulation.

ABSTRACT

Objective:To analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with chronic heart failure (CHF) complicated by sarcopenia.Methods:In this randomized controlled trial, seventy CHF patients with sarcopenia, aged 80 years or older, who had received standard CHF medication treatment and had stable conditions with preserved ejection fraction (HFpEF) from June 2021 to October 2022 at the China-Japan Friendship Hospital outpatient clinic were continuously selected. The patients were randomly divided into a test group ( n=35) and a control group ( n=35) using a random number table. The test group continued the original heart failure medication treatment, and on the basis of daily meal, supplemented with whey protein powder [37 g per serving (including 16.2 g of whey protein, 145 kcal), twice a day]; they were given resistance exercise primarily focused on resistance training (5 sets of exercises, progressively increasing to 3 days per week, twice a day, 5 sets per session, 20 repetitions per set). The control group maintained the original heart failure medication treatment plan and lifestyle. The body mass index, appendicular skeletal muscle mass index (ASMI), grip strength, Five-Times-Sit-to-Stand Test, 6-meter walking speed, 6-minute walk test, brain natriuretic peptide (BNP), left ventricular ejection fraction, ratio of early mitral flow peak velocity to early mitral annulus diastolic peak velocity (E/e′), serum albumin, hemoglobin, and serum creatinine were compared between the two groups before and after 3 months of intervention using t-tests and chi-square tests to analyze the efficacy of nutrition intervention combined with rehabilitation exercise in elderly patients with CHF complicated by sarcopenia. Results:Among the 70 patients, there were 42 males and 28 females. There was no significant difference in baseline data between the test group and the control group (all P>0.05). After 3 months of intervention, ASMI, grip strength and 6 min walking distance in the test group were all significantly higher than those in the control group [(6.43±1.07) vs (6.09±0.86) kg/m 2, (27.75±2.13) vs (23.45±0.47) kg, (361.51±58.71) vs (273.50±69.85) m], and significantly higher than those before intervention [(5.99±1.45) kg/m 2, (23.55±9.64) kg, (273.50±69.86) m]. The time of Five-Times-Sit-to-Stand Test, BNP and E/e′ in the test group were both significantly lower than those in the control group [(11.20±2.09) vs (15.36±0.46) s, (278.80±58.69) vs (400.80±87.86) ng/L, (11.10±0.81) vs (14.66±1.90)], and significantly lower than those before intervention [(18.51±2.90) s, (407.50±122.74) ng/L and (14.00±1.15)]. There was no significant difference in remaining indicators between the two groups (all P>0.05). Conclusion:Nutritional intervention combined with rehabilitation exercise primarily focused on whey protein supplementation and resistance training can significantly improve limb muscle mass, muscle strength, muscle function, and cardiac function in elderly patients with CHF complicated by sarcopenia on the basis of heart failure medication treatment.

ABSTRACT

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

ABSTRACT

OBJECTIVE@#To investigate the pharmacodynamic material basis, mechanism of actions and targeted diseases of Salicornia europaea L. (SE) based on the network pharmacology method, and to verify the antidepressant-like effect of the SE extract by pharmacological experiments.@*METHODS@#Retrieval tools including Chinese medicine (CM), PubMed, PharmMapper, MAS 3.0 and Cytoscape were used to search the components of SE, predict its targets and related therapeutic diseases, and construct the "Component-Target-Pathway" network of SE for central nervous system (CNS) diseases. Further, protein-protein interaction (PPI) network, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) function annotation of depression-related targets were analyzed to predict the antidepressant mechanism of SE. Chronic unpredictable mild stress (CUMS) model was used to construct a mouse model with depression-like symptoms. And the animals were randomly divided into 6 groups (n=10) including the normal group (nonstressed mice administered with distilled water), the CUMS group (CUMS mice administered with distilled water), the venlafaxine group (CUMS mice administered with venlafaxine 9.38 mg/kg), SE high-, medium-, and low-dose groups (CUMS mice administered with SE 1.8, 1.35 and 0.9 g/kg, respectively). Then some relevant indicators were determined for experimental verification by the forced swim test (FST), the tail suspension test (TST) and open-field test (OFT). Dopamine (DA) concentration in hippocampus and cerebral cortex, IL-2 and corticosterone (CORT) levels in blood, and nuclear factor E2 related factor 2 (Nrf2), kelch-like epichlorohydrin related protein 1 (Keap1), NAD(P) H dehydrogenase [quinone] 1 (NQO1) and heme oxygenase-1 (HO-1) levels in mice were measured by enzyme linked immunosorbent assay (ELISA) and Western blot respectively to explore the possible mechanisms.@*RESULTS@#The "target-disease" network diagram predicted by network pharmacology, showed that the potential target of SE involves a variety of CNS diseases, among which depression accounts for the majority. The experimental results showed that SE (1.8, 1.35 g/kg) significantly decreased the immobility period, compared with the CUMS group in FST and TST in mice after 3-week treatment, while SE exhibited no significant effect on exploratory behavior in OFT in mice. Compared with CUMS group, the SE group (0.9 g/kg) showed significant differences (P<0.05) in DA levels in the hippocampus and cerebral cortex. In addition, compared with CUMS control group, SE (1.8 g/kg) group showed a significant effect on decreasing the activities of CORT (P<0.05), and serum IL-2 level with no statistical significance. Finally, Western blot results showed that compared with the model group, Nrf2, Keap1, NQO1 and HO-1 protein expressions in SE group (1.8 g/kg) were up-regulated (all P<0.01).@*CONCLUSION@#The SE extract may have an antidepressant effect, which appeared to regulate Nrf2-ARE pathway and increased levels of DA and CORT in the hippocampus and cortex.

ABSTRACT

Objective:To investigate the association of postprandial hypotension(PPH)with insulin and neurotensin(NT)in very old adults.Methods:In this retrospective study, 22 people with PPH and 21 without non-PPH, aged ≥80, were enrolled from patients hospitalized at the First Division of the Health Department of China-Japan Friendship Hospital between September 2015 and October 2021.The levels of blood pressure, blood glucose, insulin and NT at fasting and 30, 60, 90 and 120 minutes after a meal were monitored.Changes in values of each parameter before and after a meal were compared between the two groups, and the correlation of the maximum decrease in postprandial blood pressure with the maximum increase in blood glucose, insulin and neurotensin was analyzed.Results:The maximum decrease in postprandial systolic blood pressure(SBP)in the PPH group was significantly higher than that in the non-PPH group[(35.5±13.2)mmHg(1 mmHg=0.133 kPa) vs.(16.0±8.6)mmHg, t=4.135, P<0.01)]. The maximum increase in postprandial insulin was significantly higher than that in the non-PPH group[(20.9±4.2)mU/L vs.(12.1±4.1)mU/L, t=3.949, P<0.01)]. There was no statistically significant difference between the PPH and non-PPH groups in the maximum increase in postprandial blood glucose[(3.6±1.8)mmol/L vs.(2.5±0.5)mmol/L, t=1.912, P>0.05)]or NT[65.7(22.0, 110.1)ng/L vs.112.2(47.2, 270.2)ng/L, Z=1.817, P>0.05)]. There was a significant positive correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in insulin( r=0.907, P<0.05). There was no correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in blood glucose( r=0.016, P>0.05). There was no correlation between the maximum decrease in postprandial systolic blood pressure and the maximum increase in NT( r=0.396, P>0.05). Conclusions:The PPH is related to abnormal increases in postprandial insulin secretion.

ABSTRACT

Objective:To investigate the prognostic significance of D-dimer level in patients with diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of 70 newly diagnosed DLBCL patients who were admitted to Tianjin People's Hospital from January 2015 to June 2019 were retrospectively analyzed. The optimal cut-off value of D-dimer for survival was determined according to the receiver operating characteristic (ROC) curve, and the patients were grouped. The differences of coagulation related indexes and clinicopathological features between patients with different D-dimer levels were compared. Kaplan-Meier method was used for univariate analysis of overall survival (OS), and Cox regression model was used for multivariate analysis of OS.Results:According to ROC curve, the best cut-off value of D-dimer for survival was 0.75 mg/L. The proportion of patients with different clinical staging, international prognostic index score, lactate dehydrogenase level had statistically significant differences between the D-dimer ≥0.75 mg/L group (36 cases) and <0.75 mg/L group (34 cases) (all P < 0.05). The prothrombin time of D-dimer ≥ 0.75 mg/L group and < 0.75 mg/L group were (13.5±0.9) s and (13.0±0.8) s, respectively, and the activated partial thromboplastin time were (37±5) s and (34±6) s, respectively,and the differences were statistically significant (all P < 0.05). Univariate analysis showed that the 5-year OS rates of DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ, international prognostic index score > 2, lactate dehydrogenase level > 240 U/L, B symptoms, D-dimer level ≥0.75 mg/L were decreased (all P < 0.05). Multivariate Cox regression analysis showed that D-dimer ≥0.75 mg/L was an independent risk factor for OS of DLBCL patients ( HR=0.368, 95% CI 0.144-0.944, P= 0.038). Conclusion:The level of D-dimer can be used as a clinical indicator to judge the prognosis of DLBCL patients, and the prognosis of patients with high D-dimer level is poor.

ABSTRACT

The over-activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamcyin (mTOR) pathway is closely related to the occurrence, development and clinical prognosis of malignant tumors. Taking this signal pathway as a target can effectively inhibit tumor progression. At present, the Food and Drug Administration of the United States has approved three drugs (CAL-101, BAY80-6946, IPI-145) for the treatment of recurrent and refractory indolent non-Hodgkin lymphoma, which demonstrates significant efficacy and a manageable safety profile.

ABSTRACT

OBJECTIVE@#To compare the curative effect between bloodletting at tip of ear with different amounts combined with western medication and western medication alone for early-stage stye.@*METHODS@#A total of 108 patients with early-stage stye were randomly divided into a 50 μL group (36 cases, 4 cases dropped off), a 100 μL group (36 cases, 2 cases dropped off) and a western medication group (36 cases, 5 cases dropped off). The patients in the western medication group were treated with levofloxacin eye drops and levofloxacin hydrochloride eye gel. Based on the treatment of the western medication group, the patients in the 50 μL group were treated with 50 μL bloodletting (about 3 drops) at tip of ear while the patients in the 100 μL group were treated with 100 μL bloodletting (about 6 drops) at tip of ear; the bloodletting was given once a day for 3 days. After treatment, the changes of visual analogue scale (VAS) and clinical effect were observed, and the patients were followed up by telephone on the 8th day.@*RESULTS@#After treatment, the VAS score in each group was reduced (0.05). One week after the onset of the disease, all the patients in the 50 μL group and 100 μL group were cured, and one patient in the western medication group was not cured, and treated with routine surgery.@*CONCLUSION@#Based on the conventional western medication treatment, bloodletting at tip of ear can significantly reduce the pain of stye, and the effect of 100 μL bleeding is better than 50 μL.

ABSTRACT

OBJECTIVE@#To explore the molecular mechanism underlying the inhibitory effects of aspirin against human breast cancer cell proliferation through bioinformatics analysis.@*METHODS@#Drug Bank 5.1.3 was searched to identify direct protein targets (DPTs) of aspirin, and the protein-protein interaction (PPI) network of the DPTs was constructed online using STRING and the signaling pathways involved were identified. The genetic alterations of 6 DPTs associated with human breast cancer was analyzed and visualized by cBio Portal and OncoPrint, respectively. The transcriptomic data of breast cancer and normal tissues were downloaded from TCGA database, and the overexpressed genes were analyzed by DECenter. The intersection between the genes associated with the DPTs obtained by STRING analysis and the differentially over-expressed genes in TCGA was determined to confirm the candidate DPTs as a potential target of aspirin, and GO functional enrichment analysis was performed using Gene Ontology. The potential targets of aspirin against the proliferation of human breast cancer cells were verified by Western blotting.@*RESULTS@#Eleven DPTs of aspirin were identified. KEGG pathway enrichment indicated that 6 genes (EDNRA, IKBKB, NFKB2, NFKBIA, PTGS2 and TP53) were associated with the occurrence and development of cancer. A total of 10 220 differentially expressed genes were identified from the TCGA database, and among them 4 genes (, , , ) were found to be the potential targets for aspirin. These genes were involved mostly in the regulation of cell cycle and cell division. Western blotting showed that aspirin could down-regulate the expression levels of several pivotal proteins that regulated cell cycle and cell division, including , , and .@*CONCLUSIONS@#, , and may be potential targets for aspirin to inhibit the proliferation of human breast cancer cells, by affecting the progress of cell cycle and cell division.

ABSTRACT

This article reports the results of tandem mass spectrometry and the mutation features of the ETFDH gene for an infant with multiple acyl-CoA dehydrogenase deficiency. The results of tandem mass spectrometry showed that C14 : 1, C8, C6, C10, and C12 increased. Exon sequencing was performed on this infant and his parents and revealed double heterozygous mutations in the ETFDH gene of the infant: c.992A>T and c.1450T>C. The former was inherited from his mother, and the latter was inherited from his father. c.1450T>C was shown to be the pathogenic mutation in the HGMD database. PolyPhen2, SIFT, and PROVEAN all predicted that the novel mutation c.992A>T might be pathogenic, and the mutant amino acids were highly conserved across various species. The findings expand the mutation spectrum of the ETFDH gene, and provide molecular evidence for the etiological diagnosis of the patient with multiple acyl-CoA dehydrogenase deficiency as well as for the genetic counseling and prenatal diagnosis in the family.

ABSTRACT

Objective To evaluate the efficacy and safety of short-term deep sedation strategy in patients with spontaneous intracerebral hemorrhage (ICH) after surgery. Methods A perspective, randomized, parallel-group study was conducted. Adult patients with spontaneous ICH and undergoing craniotomy admitted to Daxing Teaching Hospital of Capital Medical University from December 2015 to November 2016 were enrolled. The patients who received surgery were randomly divided into a short-term deep sedation and a slight and middle sedation group. Sufentanil was used as an analgesic drug in all patients and midazolam was used as a sedative after the operation. The patients in the slight and middle sedation group received midazolam 0.05-0.10 mg/kg with a goal of mild sedation [Richmond agitation and sedation scale (RASS) score of -2-1]. The patients in the short-term deep sedation group received midazolam 0.1-0.2 mg/kg with a goal of deep sedation (RASS score of -4 to -3) and a duration of no more than 12 hours. Postoperative sedation, blood pressure changes, laboratory indexes, residual hematoma and clinical outcomes were recorded in two groups. Results During the study, a total of 183 patients with spontaneous ICH were collected, excluding who was older than 65 years, with shock, and with preoperative Glasgow coma score (GCS) of 3. 106 patients were enrolled in this study, and 53 patients were assigned to the short-term deep sedation group and slight and middle sedation group, respectively. In the slight and middle sedation group, 4 patients received reoperation because of repeated hemorrhage and no patient operated repeatedly in the short-term deep sedation group, and there was a significant difference between the two groups (χ2= 4.000, P = 0.045). The number of patients undergoing tracheotomy in the short-term deep sedation group was significantly lower than that in the slight and middle sedation group (9 cases vs. 21 cases,P < 0.05). RASS score within 12 hours after operation of the patients in the short-term deep sedation group was lower than that in slight and middle sedation group [-4 (-4, -2) vs. -2 (-3, -1) at 4 hours, -4 (-4, -2) vs. -1 (-2, 0) at 8 hours,-3 (-4, -2) vs. 0 (-2, 1) at 12 hours, all P < 0.01], sudden restlessness was significantly reduced [times: 1 (0, 1) vs. 3 (2, 3), P < 0.01], and postoperative sedation duration was significantly prolonged [hours: 14.0 (8.3, 20.8) vs. 8.9 (3.4, 15.3), P < 0.05]. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) within 12 hours after operation in the short-term deep sedation group were significantly lower than those of the slight and middle sedation group [SBP (mmHg, 1 mmHg = 0.133 kPa): 136.8±30.5 vs. 149.1±33.5, DBP (mmHg): 85.0 (70.8, 102.3) vs. 89.0 (69.2, 116.7), both P < 0.05]. There were no significant differences in the arterial blood gas, routine blood test or coagulation function between the two groups at 24 hours after operation. The volume of residual hematoma at 2, 7 and 14 days after operation in the short-term deep sedation group was significantly decreased as compared with slight and middle sedation group (mL: 16.4±15.6 vs. 38.2±22.2 at 2 days, 9.6±8.7 vs. 20.6±18.6 at 7 days, 1.2±1.0 vs. 4.4±3.6 at 14 days, all P < 0.05), number of deaths in 3 months were significantly less (5 cases vs. 13 cases), and the patients with favorable prognosis were increased significantly (39 cases vs. 12 cases, both P < 0.05). Conclusion The study results showed that short-term deep sedation strategy after surgery can reduce the incidence of adverse events and improve the prognosis of patients with spontaneous ICH, so it is safe and effective.

ABSTRACT

To establish an HPLC-ELSD method for the quantification of triterpenoids in the fruits of Buddleja lindleyana. The RP-HPLC-ELSD method was used for the determination of triterpenoids in B. lindleyana fruits, which were collected from different habitats. The column used was a packed with 5 μm stationary phase Waters SunFireTM C₁₈ (4.6 mm×150 mm, 5 μm). The mobile phase consisted of Methanol-water(82∶18) at a flow rate of 1 mL•min⁻¹. Column temperature: 30 ℃. ELSD conditions: drift tube temperature: 106 ℃; carrier gas (nitrogen) flow rate: 1.5 L•min⁻¹; amplification factor: 1. The calibration curves showed good linear relationship on a range from 0.702 to 28.08 μg(r=0.999 2) for Clinoposaponin III, 0.390 to 15.60 μg(r=0.998 9) for Desrhamnoverbascosaponin and 0.192 to 7.68μg(r=0.999 0) for Mimengoside I. The average recovery rate(n=6) were 99.41%, 99.08% and 98.67% and it's RSD were 0.86%, 1.56% and 1.80%. This method can be used to determine the contents of triterpenoids in the fruits of Buddleja lindleyana for its simplicity, accurateness and reliability.

ABSTRACT

Objective To study the effects of Weibimei and its Chinese medicine portions(cortex frangulae, fennel powder, acorus tatarinowii, glycyrrhizae and asparagus) on cell cycle regulation in gastric cancer cells and growth inhibition in gastric cancer Xenografts.Methods Gastric cancer SGC-7901 cells were normally cultured and treated with Weibimei, extractum glycyrrhizae, cortex frangulae, fennel powder, acorus tatarinowii and asparagus.Then, the proliferation of SGC-7901 cells were detected by MTT assay, their effect on SGC-7901 cell cycle were measured by flow cytometry, and the expression of cell cycle related proteins were examined by Western blot.Animal models of SGC-7901 cells xenografts in nude mice were constructed to evaluate the growth inhibition effects of Weibimei and its Chinese medicine portions, and the expression of STAT3,p-STAT3, Cyclin D1, Bcl-2 and Survivin in gastric tumors were detected by immunohistochemical assays.Results Weibimei and its three kinds of Chinese medicine portions, cortex frangulae, fennel and acorus tatarinowii could obviously inhibit the proliferation of SGC-7901 cells, compared to control group, with a statistical significant difference (P<0.05).The cell cycle of SGC-7901 was arrested at G1 phase with cortex frangulae, fennel and acorus tatarinowii treatment, the expression of Cyclin A, B, D, E were decreased significantly (P<0.05).However, no significant effects was found in glycyrrhizae or asparagus group.Xenografts tumor sizes in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were much smaller than that in saline group or Triple Therapy group (three-kinds-drugs-combination for the treatment of gastric ulcer) (P<0.05).Xenografts experiments showed that the tumor growth in nude mice in Weibimei, cortex frangulae, fennel or acorus tatarinowi groups were significantly smaller than that in control group or in Triple Therapy Group (P<0.05), and phosphorylated STAT3, and STAT3 signaling targeted genes, including Bcl-2, Cyclin D1 and Survivin were all significantly down-regulated by immunostaining.Conclusion Weibimei and its Chinese medicine portions including cortex frangulae, fennel and acorus tatarinowii can could significantly inhibit the growth of SGC-7901 cells proliferation and arrested the cell cycle of G1 phase in vitro, and inhibit gastric cancer xenografts in nude mice in vivo.
