ABSTRACT

Platelet to lymphocyte ratio (PLR) is a prognostic marker in human hepatocellular carcinoma (HCC) however, its utility in canine HCC has not been explored. The aim of the study was to determine if PLR could predict survival outcomes in 42 dogs with HCC. PLR was not a significant predictive factor (p = 0.15) but lymphopenia alone was significantly correlated with a reduced probability of survival (p = 0.024). Further studies are needed to evaluate if peripheral lymphocyte count mirrors that of the tumor microenvironment in canine HCC.

ABSTRACT

Exosomes are nanoscale extracellular vesicles that are secreted by a variety of cells in the body. They carry particular miRNA, protein molecules, transcription factors, and other information molecules, and they play a role in the pathophysiological regulation of a number of diseases in the body. Exosomes can persist steadily in biological tissues and bodily fluids. Exosomes have quickly advanced in ophthalmology in recent years due to the extensive studies of exosomes in a variety of fields, such as diabetic retinopathy, age-related macular degeneration, autoimmune uveitis, corneal disease, glaucoma, and other diseases. The number of people who are blind caused by diabetic retinopathy is rising as living standards rise. However, it is still unclear how diabetic retinopathy works. In recent years, many studies have found that exosomes play an important role in diabetic retinopathy. In this paper, the most recent developments in exosome studies as they relate to the pathogenesis and progression of diabetic retinopathy are reviewed.

ABSTRACT

Synephrine is a natural small-molecule alkaloid found in Aurantii fructus immaturus with versatile biological activities, but its derivatives have been rarely studied so far. Based on the multi-target drug design strategy, the phenolic hydroxyl and secondary amino group of synephrine were modified structurally by the molecular splicing method in this study and thus five intermediates and fifteen target molecules were designed and synthesized. These compounds were evaluated with certain human pathogenic bacteria and fungi, and found that the inhibitory activities of IM4 and IM5 against E.coli are comparable to those of eight fluoroquinolones; TM1n showed stronger inhibitory activity against drug-resistant C. trobicans and drug-resistant C. albicans than the positive control drug fluconazole. TM1d and TM1f against C. albicans ATCC90023, TM1o and TM1f against drug-resistant C. albicans, and TM1f against C. parapsilosis ATCC22019 are all comparable to fluconazole, all of which have the potential for in-depth research. In this study, synephrine derivatives with strong inhibitory activities against human pathogenic fungi were discovered for the first time, which provided a new idea for the further study of synephrine.

ABSTRACT

Objective: To summarize the clinical characteristics of patients with Takotsubo syndrome (TTS) from China and compare these features with patients from Europe/North America. Methods: We reviewed case reports published between 1990 and 2020 with the key words of "Takotsubo syndrome" "stress cardiomyopathy" "apical balloon syndrome" and "broken heart syndrome", in Wanfang, CNKI, Pubmed and Web of Science databases, and 1 294 articles were identified, including 128 articles reporting 163 cases in China and 1 166 articles reporting 1 256 cases in Europe/North America. The characteristics of demographics, triggers, symptoms, electrocardiogram, echocardiography, left ventriculogram,coronary angiography, treatment and prognosis were analyzed and compared between Chinese and European/North American cases. Results: A total of 1 294 articles (1 419 cases: 163 from China, 1 256 from Europe/North America) were included in the final analysis. The characteristics of Chinese cases included: (1) demographic:the age was (59.6±16.9) years, which was similar with that of European/North American ((59.7±17.4) years, P=0.90), and female accounting for 78.5% (128/163), which was lower than that of European/North American (85.4% (1 073/1 256), P=0.02). (2) Triggers:mental triggers accounted for 48.5% (79/163), physical triggers accounted for 43.6% (71/163), and no triggers accounted for 7.9% (13/163), respectively. Compared with Europe/North America, the ratio of patients with mental triggers was higher in China, while the ratio of patients with physical triggers and no triggers was lower (P<0.05). (3) Symptoms: chest pain (52.8% (86/163)), chest tightness (35.0% (57/163)), shortness of breath (33.1% (54/163)), dizziness (16.0% (26/163)), sweating (15.3% (25/163)), palpitations (12.3% (20/163)), syncope (9.2% (15/163)) abdominal pain/diarrhea (8.6% (14/163)), hypotension (7.4% (12/163)), and fatigue (1.2% (2/163)) were illustrated in sequence. Compared with patients in Europe/North America, the ratio of patients with chest tightness, dizziness, sweating, palpitations, abdominal pain/diarrhea was higher in Chinese patients, while the ratio of patients with hypotension was lower in Chinese patients (P<0.05). (4) Electrocardiogram: main manifestations were myocardial ischemia symptoms, such as ST-segment elevation (63.8% (104/163)), T wave inversion (46.0% (75/163)), ST-segment depression (8.6% (14/163)). Compared with European/North American, the ratio of patients with ST-segment elevation, T wave inversion, and atrioventricular block was higher in Chinese patients (P<0.05). (5) Echocardiography and imaging:apical dyskinesia (59.5% (97/163)) and apical/left ventricular bulbar dilation (36.2%(59/163)) dominated the echocardiography findings. Compared with European/North American, the ratio of patients with apical dyskinesia, apical/left ventricular bulbar dilation, and mitral regurgitation was higher in Chinese patients, while the ratio of patients with dyskinesia in other parts and left ventricular ejection fraction<50% was lower in Chinese patients (P<0.05). Left ventricular angiography showed 36.2% (59/163) of apical dyskinesia in Chinese patients, which was higher than that reported in European/North American patients, and 38.7% (63/163) of apical/left ventricular bulbar dilation was reported in Chinese patients, which was similar to that reported in European/North American patients. Coronary angiography showed percent of no stenosis or stenosis less than 50% was 87.1% (142/163), which was similar to that reported in European/North American patients (P>0.05). The typical type of TTS accounted for 96.3% (157/163), which was significantly higher than that reported in European/ American patients, while the ratio of basal type and midventricular type was lower (P<0.01). (6) Treatment and prognosis:the applied drugs in China were listed in order as following, β-blockers (41.1% (67/163)), antiplatelet agents (37.4%(61/163)), ACEI/ARB (36.2%(59/163)), anticoagulants (27.0%(44/163)), diuretics (19.6% (32/163)), etc. Compared with Europe/North America, the ratio of antiplatelet agents, anticoagulants, statins, diuretics, and nitrates use was higher in China (P<0.05), while the use of oxygen therapy and IABP was similar (P>0.05). The hospital mortality in China was 5.5% (9/163), during 1-year follow-up the recurrence rate was 3.7% (6/163) and the mortality was 0. The prognosis was similar with that in Europe/North America. Conclusions: Compared with TTS cases in Europe/North America, TTS cases in China also occur usually in middle-aged and elderly women, most of whom have mental/physical triggers and typical imaging manifestations, followed by a low hospital mortality rate and recurrence rate.

ABSTRACT

Cell aging is an extremely complex process, which is characterized by mitochondrial structural dysfunction, telomere shortening, inflammatory microenvironment, protein homeostasis imbalance, epigenetic changes, abnormal DNA damage and repair, etc. Aging is usually accompanied by structural and functional damage of tissues and organs which further induces the occurrence and development of aging-related diseases. Aging includes physiological aging caused by increased age and pathological aging induced by a variety of factors. Noteworthy, as a target organ directly contacting with the outside air, lung is more prone to various stimuli, causing pathological premature aging which is lung aging. Studies have found that there is a certain proportion of senescent cells in the lungs of most chronic respiratory diseases. However, the underlying mechanism by which these senescent cells induce lung senescence and their role in chronic respiratory diseases is still obscure. This paper focuses on the causes and classification of lung aging, the internal mechanism of lung aging involved in chronic respiratory diseases, and the application of anti-aging treatments in chronic respiratory diseases. We hope to provide new research ideas and theoretical basis for the clinical prevention and treatment in chronic respiratory diseases.

ABSTRACT

Objective:To analyze the demographic and clinical characteristics of elderly inpatients with osteoporotic femoral neck fractures(OFNF).Methods:Clinical data of 1 227 patients with OFNF treated at the department of orthopedics of Beijing Hospital from January 2010 to December 2019 were analyzed retrospectively, including 377 male and 850 female patients.Ten-year trends in the OFNF constituent ratio, patient age, average length of stay and hospitalization expenses were examined, and differences in demographic and clinical characteristics between different genders were analyzed.Results:From 2010 to 2017, the constituent ratio of OFNF patients increased each year, and the number of OFNF patients decreased slightly in 2018 and 2019.The age of onset in both male and female patients was the highest at the ages of 80-89(46.8% or 574/1 227). In the distribution of educational level, people with no education made up the highest proportion(36.7% or 450/1 227). The seasonal distribution of the disease was the highest in autumn(27.8% or 341/1 227). The constituent ratio of urban areas was higher than that of rural areas(54.6% or 670/1 227 vs.45.4% or 557/1 227). In the distribution of fracture types, the constituent ratio of 31-B2 fractures was the highest in both male and female patients.Of the causes of injury, the constituent ratio of falls and indoor activities was the highest.Hypertension, spinal degenerative diseases and knee and hip osteoarthritis ranked in the top three of concomitant diseases.The constituent ratio of previous fractures in females was significantly higher than that in males.In the past ten years, the average hospitalization length of OFNF patients showed a downward trend, and the change in average hospitalization cost showed abrupt fluctuations.From 2009 to 2016, the hospitalization cost showed an upward trend, with the highest in 2016, and then decreased year by year. Conclusions:In the past ten years, the number and constituent ratio of OFNF patients increased steadily in the first eight years, but decreased slightly or reached a plateau in the past two years.The education level, history of bone fractures, hypertension, spinal degenerative diseases and knee and hip osteoarthritis of OFNF patients were correlated with sex, while age distribution, seasonal distribution, urban and rural distribution, cause of injury, fracture classification and other concomitant diseases were not correlated with sex.In the past ten years, the average hospitalization length of OFNF patients trended downward, the average hospitalization cost showed an upward trend from 2009 to 2016, and decreased year by year after 2016.The medical policy reform in 2016 played a significant role in controlling medical expenses.

ABSTRACT

Lower respiratory tract infection (LRTI) induced by respiratory syncytial virus (RSV) is an important cause of hospitalization for infants. Compared with adults, infants are more likely to cause serious respiratory diseases after RSV infection due to the specific immature airway structure and immune system. The balance of immune resistance and immune tolerance of the host is critical to effective virus clearance and disease control. This paper reviews the relationship between RSV infection and respiratory diseases in infancy, the influence factors of the high pathogenicity of RSV infection in early life, as well as the research progress of anti-RSV therapy, and expands the specific molecular events regulating immune resistance and immune tolerance. We expect to present new ideas for the prevention and treatment of RSV-related respiratory diseases in clinical practice.

ABSTRACT

OBJECTIVE@#To analyze the overall survival (OS) of elderly acute myeloid leukemia (AML) patients treated with oral arsenic-containing Qinghuang Powder (, QHP) or low-intensity chemotherapy (LIC).@*METHODS@#Forty-two elderly AML patients treated with intravenous or subcutaneous LIC (1 month for each course, at least 3 courses) or oral QHP (3 months for each course, at least 2 courses) were retrospectively analyzed from January 2015 to December 2017. The main endpoints of analysis were OS and 1-, 2-, 3-year OS rates of patients, respectively. And the adverse reactions induding bone marrow suppression, digestive tract discomfort and myocardia injury were observed.@*RESULTS@#Out of 42 elderly AML patients, 22 received LIC treatment and 20 received QHP treatment, according to patients' preference. There was no significant difference on OS between LIC and QHP patients (13.0 months vs. 13.5 months, >0.05). There was no significant difference on OS rates between LIC and QHP groups at 1 year (59.1% vs. 70.0%), 2 years (13.6% vs. 15%), and 3 years (4.6% vs. 5.0%, all >0.05). Furthermore, there was no significant difference of OS on prognosis stratification of performance status > 2 (12 months vs. 12 months), age> 75 year-old (12.0 months vs. 12.5 months), hematopoietic stem cell transplant comorbidity index >2 (12 months vs. 13 months), poor cytogenetics (12 months vs. 8 months), and diagnosis of secondary AML (10 months vs. 14 months) between LIC and QHP patients (>0.05).@*CONCLUSION@#QHP may be an alternative treatment for elderly AML patients refusing LIC therapy.

ABSTRACT

Objective To investigate the clinical effects of Qinghuang powder, low-intensity chemotherapy and Qinghuang powder alternated with low-intensity chemotherapy in the treatment of elderly acute myeloid leukemia patients progressed from myelodysplastic syndromes (MDS-AML). Methods A total of 32 elderly patients with MDS-AML treated in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2014 to December 2017 were retrospectively analyzed. Of them, 12 patients received Qinghuang powder (Qinghuang powder group), 6 patients received Qinghuang powder alternated with low-intensity chemotherapy (alternating group), and 14 patients received low-intensity chemotherapy (low-intensity chemotherapy group), based on the real world of patient's voluntary choice of treatment. The efficacy and adverse reactions in the 3 groups were observed. Results The overall response number of Qinghuang powder, alternating, and low-intensity chemotherapy groups were 2, 2 and 4 cases, respectively, there was no significant difference among the 3 groups (P> 0.05). The median overall survival time of 3 groups were 14, 12 and 8 months, respectively, there was no significant difference among the 3 groups (P> 0.05). Two cases in Qinghuang powder group presented with gastrointestinal reactions; 3 cases in alternating group with myelosuppression, 2 cases with liver function damage, and 2 cases with gastrointestinal reaction; 11 cases in low-intensity chemotherapy group presented with bone marrow suppression, 3 cases with liver function damage, 7 cases with gastrointestinal reactions, and 2 cases with myocardial enzyme changes. The incidences of myelosuppression, liver function damage and myocardial enzyme changes in Qinghuang powder group were lower than those in the alternating group and low-intensity chemotherapy group. Conclusion The efficacy of Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy for the treatment of elderly MDS-AML is not worse than the low-intensity chemotherapy, furthermore Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy has fewer adverse reactions and better tolerance.

ABSTRACT

Objective@#To investigate the clinical features and prognostic factors of extrahepatic biliary neuroendocrine neoplasms(EB-NENs).@*Methods@#The clinical data and survival of 21 patients with EB-NENs admitted from May 2014 to May 2018 were analyzed retrospectively.@*Results@#These 21 EB-NENs patients accounted for 1.6% (21/1313) of all biliary tract neoplasms treated during the study period. Seven (33.3%) cases had lymph node metastasis. Five (23.8%) suffered from distant metastasis. The follow up time was (4~46.5) months with median survival time of (23.23 ±4.17) months. Univariate analysis showed that the risk factors for survival were tumor TNM stage (χ2=9.066, P=0.003), lymph node metastasis(χ2=6.399, P=0.011) and distant metastasis (χ2=9.808, P=0.002). By multivariate analysis, independent risk factors were tumor TNM stage(P=0.008, RR=3.003, 95% CI: 1.332~6.774), lymph node metastasis(P=0.023, RR=5.382, 95% CI: 1.261~22.971) and distant metastasis or not(P=0.007, RR=7.423, 95% CI: 1.730~31.851).@*Conclusion@#EB-NENs was a rare malignant tumor with poor prognosis. Tumor TNM stage, lymph node metastasis and distant metastasis were independent prognostic factors for EB-NENs patients.

ABSTRACT

Objective@#To analyze the gene mutations in the patients with myelodysplastic syndromes (MDS).@*Methods@#Forty-seven patients with MDS newly diagnosed in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2016 to July 2017 were enrolled. NGS 127-gene panel was used to detect the gene mutations, and the relationship between the gene mutations and the clinicopathological features was also analyzed.@*Results@#Thirty-one (66.0 %) cases had gene mutations in 47 patients with MDS, and 23 gene mutations were detected with clinical significances. There were 7 mutant genes with a mutation frequency over 5 % in the population, including U2AF1 (23.4 %), SF3B1 (12.8 %), ASXL1 (10.6 %), TET2 (8.5 %), BCOR (8.5 %), TP53 (8.5 %) and DNMT3A (6.4 %) in turn. Among 31 patients with gene mutations, 16 (51.6 %) patients had ≥ 2 synergistic mutations, and 12 cases had synergistic mutations in different genetic functional groups, which was higher than that in same genetic functional groups (4 cases). There was a tendency of coexistence in IDH2-KRAS, IDH2-SRSF2, IDH2-STAG2, KRAS-SRSF2, KRAS-STAG2, RUNX1-PHF6, EZH2-ASXL1, EZH2-ZRSR2, and NPM1-NRAS (all P < 0.05). The variant allele frequency (VAF) of signaling pathway related genes including JAK2, KRAS, NRAS, SH2B3 was low in general and in a sub-clone status. JAK2 gene mutation was observed in 1 case with MDS-U. SH2B3 gene mutation was observed in a patient with very poor prognosis of karyotype. SETPB1 and EZH1 gene mutations were observed in two patients with high-risk revised international prognostic scoring system (IPSS-R).@*Conclusions@#The common mutated genes include U2AF1, SF3B1, ASXL1 and TET2. The genes in different genetic functional groups tend to synergistic mutations. Gene mutations can be used to predict the prognosis of diseases and become the target in the treatment of MDS.

ABSTRACT

Objective To investigate the effect and mechanism of programmed cell death 4 ( PDCD4 ) on radiosensitivity of pancreatic cancer cells. Methods Pancreatic cancer tissues and corresponding adjacent tissues were collected, the expression level of PDCD4 was detected by RT-PCR and Western blot. Human pancreatic cancer cells Sw1990 were transfected with PDCD4 overexpression vector ( group pIRES2-PDCD4 ) , empty vector ( pIRES2 group ) , and treated with transfection reagent, respectively. The expression level of PDCD4 was detected by RT-PCR and Western blot. After radiation treatment, cell apoptosis was detected by flow cytometry, cell survival was detected by clone assay, and the expression levels ofβ-catenin, c-myc and Cleaved Caspase-3 were detected by Western blot. Results The expression of PDCD4 mRNA and protein in pancreatic cancer tissues was significantly lower than that in adjacent tissues (t=4. 869, 9. 208, P<0. 05). The expression of PDCD4 mRNA and protein in pIRES2-PDCD4 group was significantly lower than that in the non-transfection group ( t =9. 074, 18. 927, P <0. 05). After radiation, the apoptosis rate and Cleaved Caspase-3 level in the pIRES2-PDCD4 group were significantly higher than those in the non-transfection group (t =3. 670, 4. 086, P <0. 05), while the expression levels of β-catenin and c-myc in the cells were significantly lower than those in the non-transfection group (t =9. 242, 17. 644, P <0. 05). The radiosensitivity of pIRES2-PDCD4 group was higher than that of non-transfection group, and the sensitization ratio was 1. 843. Conclusions PDCD4 can increase radiosensitivity and promote apoptosis of pancreatic cancer cells, to which the Wnt signaling pathway may be related.

ABSTRACT

Objective To investigate the treatment efficacy of capecitabine combined with TACE for hepatic metastases after colorectal carcinoma resection.Methods The clinical data of 94 patients who were treated for hepatic metastases after colorectal carcinoma resection from June 2012 to December 2014 were retrospectively analyzed.The patients were divided into the combined group (48 patients) who underwent combined treatment of transcatheter arterial chemoembolization (TACE) and capecitabine,and the control group (46 patients) who were treated with TACE alone.The drug toxicities induced by chemotherapy in patients of the two groups were noted.The short-term outcomes and serum tumor markers were compared at 3-months after completion of TACE.All the patients were followed up and their overall survival was recorded.Results There was no significant difference in the frequency of TACE between the two groups (P > 0.05).There were significant differences in the short-term outcomes at 3-month after completion of TACE (Z =2.000,P < 0.05).The RR (complete response + partial response) and CBR (complete response + partial response + stable disease) were higher in the combined group than those in the control group [(52.1% vs.32.0%) and (95.8% vs.87.0%),respectively],although the differences were not statistically significant (both P >0.05).There were greater declines in CEA and CA19-9 levels at 3-month after completion of TACE in the combined group than the control group [(47.1 ± 10.3 vs.35.1 ±8.4) μg/L,(78.7 ± 19.6 vs.65.3 ± 17.0) kU/L],but the differences were not significant (t1 =5.776,t2 =7.849,both P < 0.05).Toxic reactions were more common in the combined group than those in the control group,which included bone marrow suppression (39.6% vs.30.4%) and peripheral neuritis (47.9% vs.34.8%).Again,the differences were not significant (P > 0.05).The median survivals were 17.3 months and 13.5 months,and 1-year survival rates were 72.9% and 52.1% in the combined group and the control group,respectively (x2 =4.325,P < 0.05).There were significant differences in the survival between the two groups (x2 =4.097,P < 0.05).Conclusions Capecitabine combined with TACE produced better treatment results for hepatic metastases after colorectal carcinoma resection.The short-term outcomes of the combined treatment was suDerior to TACE alone,and the treatment toxicities could be tolerated.

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of Yishen Zhongzi Pill (YZP) on the sperm motility of Shen-essence deficiency syndrome (SEDS) patients.</p><p><b>METHODS</b>Totally 144 patients were randomly assigned to the treatment group (71 cases) and the control group (73 cases). Ten cases dropped out during the therapeutic course. A total of 134 patients completed this clinical study, 67 in each group. Patients in the treatment group took YZP (6 g each time, twice daily), while those in the control group took Wuzi Yanzong Pill (6 g each time, twice daily). The therapeutic course for all was one month. Changes of the sperm motility, clinical efficacy, and Chinese medical symptoms scores were observed between the two groups before and after treatment.</p><p><b>RESULTS</b>Compared with before treatment in the same group, percentages of class a spermatozoa and class a + b spermatozoa were enhanced in the two groups after treatment (P <0. 01). Besides, they were higher in treatment group than in the control group (P <0. 05). The total effective rate of the treatment group was 77. 61 % (52/67 cases), while it was 58. 21 % (39/67 cases) in the control group. It was better in the treatment group than in the control group (Z= -2. 914, P =0. 004). Compared with before treatment in the same group, scores for Chinese medical symptoms decreased in the two groups (P <0. 01). The difference of pre-post integrals was higher in the treatment group than in the control group (P <0. 01).</p><p><b>CONCLUSION</b>YZP showed favorable effect in treating asthenospermia patients with SEDS and could effectively elevate the motility of sperm.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To identify non-invasive biomarkers for diagnosis and/or prognosis of liver fibrosis in chronic hepatitis B (CHB).</p><p><b>METHODS</b>Peripheral blood samples were obtained from 48 patients with CHB, including 24 with mild fibrosis (stage 1, S1) and 24 with severe fibrosis (stage 4, S4), and subjected to Ficoll density gradient centrifugation in order to obtain enriched samples of peripheral blood mononuclear cells (PBMCs).The PBMC proteomes of the two groups were assessed by first separating the total proteins by two-dimensional gel electrophoresis (2DE) and then identifying the differentially expressed proteins by liquid chromatography combined with tandem mass spectrometry (LCMS/MS).</p><p><b>RESULTS</b>The enriched PBMC samples from the S1 group and the S4 group had similar amounts of platelets [(19.268+/- 6.413) * 109/L and(19.480+/- 6.538) * 109/L, respectively); however, for both, the platelet amounts were 5 to 15-fold lower than that of the normal reference (100-300 *109/L). There was no significant difference found between the platelet amounts in the S1 patients and healthy controls (P=0.930). Twelve differentially expressed proteins were identified through 2DE-LC-MS/MS, including proteins such as moesin and NADH dehydrogenase [ubiquinone] iron-sulfur protein 3 that are involved in various biological processes like cell movement, cell adhesion, kinase signaling and transcription.</p><p><b>CONCLUSION</b>s The 12 proteins with differential expression in S1 and S4 patients with CHB and liver fibrosis may represent markers related to development and/or progression of liver fibrosis.</p>
