RESUMO

OBJECTIVE@#To study the use of Chinese medicine (CM) in cancer patients in southern China.@*METHODS@#A total of 1,950 cancer patients finished questionnaires in four provinces in southern China. The survey included socio-demographic and clinical characteristics of participants, dosage forms, efficacy, and side effects.@*RESULTS@#The study results showed that cancer patients with higher education (>12 years) were more likely to accept the treatment of Chinese herbs. There were 54.61% (1,065 cases) of patients chose Chinese herbs for the initial treatment and 14.46% (282 cases) chose Chinese herbs as monotherapy. Most patients (54.51%, 1,063 cases) continuously used CM for more than 6 months, and a few of them (212 cases) used CM for up to 3 years. All kinds of dosage forms of CM had been used, including CM decoction, CM patent prescription and CM injection. Concerning the efficacy in the view of patients, 40.31% (786 cases) believed that it would be effective to take Chinese herbs before they starting the anti-cancer treatment, and the percentage increased to 81.08% after 1-month CM treatment. The effect of Chinese herbs was mainly demonstrated by symptom relief and improvement of quality of life, and 8.31% (162 cases) of patients experienced control of tumor growth and decreased tumor markers. Furthermore, only 14.31% (279 cases) participants reported that they experienced side effects during CM treatment.@*CONCLUSION@#This large scale investigation reflects the current situation of domestic CM usage objectively and comprehensively, which might provide new ways for cancer treatment.

RESUMO

BACKGROUND@#Since the outbreak of coronavirus disease 2019 (COVID-19), human mobility restriction measures have raised controversies, partly because of the inconsistent findings. An empirical study is promptly needed to reliably assess the causal effects of the mobility restriction. The purpose of this study was to quantify the causal effects of human mobility restriction on the spread of COVID-19.@*METHODS@#Our study applied the difference-in-difference (DID) model to assess the declines of population mobility at the city level, and used the log-log regression model to examine the effects of population mobility declines on the disease spread measured by cumulative or new cases of COVID-19 over time after adjusting for confounders.@*RESULTS@#The DID model showed that a continual expansion of the relative declines over time in 2020. After 4 weeks, population mobility declined by -54.81% (interquartile range, -65.50% to -43.56%). The accrued population mobility declines were associated with the significant reduction of cumulative COVID-19 cases throughout 6 weeks (ie, 1% decline of population mobility was associated with 0.72% [95% CI: 0.50%-0.93%] reduction of cumulative cases for 1 week, 1.42% 2 weeks, 1.69% 3 weeks, 1.72% 4 weeks, 1.64% 5 weeks, and 1.52% 6 weeks). The impact on the weekly new cases seemed greater in the first 4 weeks but faded thereafter. The effects on cumulative cases differed by cities of different population sizes, with greater effects seen in larger cities.@*CONCLUSIONS@#Persistent population mobility restrictions are well deserved. Implementation of mobility restrictions in major cities with large population sizes may be even more important.

RESUMO

Chemotherapy is one of the main treatments for malignant tumors, aiming to kill tumor cells and improve patient survival. However, the new study have found that chemotherapy also promotes distant metastasis of tumors while treating tumor, and the article will give further new meaning to "chemotherapy side effects." On the other hand, tumor metastasis is the main cause of short-term survival of patients. Inhibition of tumor metastasis caused by chemotherapy is a hot topic that should be widely concerned. Modern research suggests that chemotherapeutic drugs promote tumor metastasis by inducing changes in the biological characteristics of tumors and causing a series of "host reactions". The article summarizes the mechanisms of chemotherapy-induced tumor metastasis in combination with the seed and soil theory related to tumor metastasis.

RESUMO

Emerging evidence indicates that aldosterone and mineralocorticoid receptors (MRs) are associated with the pathogenesis of erectile dysfunction. However, the molecular mechanisms remain largely unknown. In this study, freshly isolated penile corpus cavernosum tissue from rats was treated with aldosterone, with or without MRs inhibitors. Nuclear factor (NF)-kappa B (NF-κB) activity was evaluated by real-time quantitative PCR, luciferase assay, and immunoblot. The results demonstrated that mRNA levels of the NF-κB target genes, including inhibitor of NF-κB alpha (IκB-α), NF-κB1, tumor necrosis factor-alpha (TNF-α), and interleukin 6 (IL-6), were higher after aldosterone treatment. Accordingly, phosphorylation of p65/RelA, IκB-α, and inhibitor of NF-κB kinase-β was markedly increased by aldosterone. Furthermore, knockdown of MRs prevented activation of the NF-κB canonical pathway by aldosterone. Consistent with this finding, ectopic overexpression of MRs enhanced the transcriptional activation of NF-κB by aldosterone. More importantly, the MRs antagonist, spironolactone blocked aldosterone-mediated activation of the canonical NF-κB pathway. In conclusion, aldosterone has an inflammatory effect in the corpus cavernosum penis, inducing NF-κB activation via an MRs-dependent pathway, which may be prevented by selective MRs antagonists. These data reveal the possible role of aldosterone in erectile dysfunction as well as its potential as a novel pharmacologic target for treatment.

RESUMO

<p><b>OBJECTIVE</b>To evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.</p><p><b>METHODS</b>Block randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.</p><p><b>RESULTS</b>The 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).</p><p><b>CONCLUSIONS</b>KA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the association of the platelet-activating factor receptor (PAFR) gene rs5938, rs313152 and rs76744145 polymorphisms with coronary heart disease (CHD) and blood stasis syndrome (BSS) of CHD in Chinese Han population.</p><p><b>METHODS</b>A total of 570 CHD patients (299 with BSS and 271 with non-BSS) and 317 controls were enrolled. The PAFR gene rs5938, rs313152 and rs76744145 polymorphisms were genotyped using the multiplex SNaPshot technology. The statistical analysis was conducted using a multiple variable logistic regression model.</p><p><b>RESULTS</b>Significant differences were detected in the genotypes frequency distributions of the rs5938 (P<0.01), but not the rs313152 (P>0.05), between the controls and CHD patients. Individuals with an rs5938 or rs313152 mutated allele had a low risk for CHD [adjusted odds ratio (aOR)=0.35, 95% confidence interval (CI): 0.23 to 0.56, P<0.01; aOR=0.65, 95% CI: 0.46 to 0.91, P<0.05, respectively]. After the CHD patients were stratified as BSS or non-BSS according to their Chinese medicine patterns, the rs5938 polymorphism mutated alleles had a significant association with a low risk for BSS of CHD (aOR=0.32, 95% CI: 0.18 to 0.57, P<0.01) and non-BSS of CHD (aOR=0.31, 95% CI: 0.17 to 0.55, P<0.01). The rs313152 polymorphism was associated with a low risk for BSS (aOR=0.51, 95% CI: 0.33 to 0.79, P<0.01), but not for non-BSS (aOR=1.22, 95% CI: 0.81 to 1.85, P<0.05). Furthermore, the interaction effect of the rs5938 and rs313152 polymorphisms for BSS of CHD was significantly based on an aOR value associated with the combination of the rs5938 GT genotype with the rs313152 TC genotype of 0.27 (95% CI: 0.1 to 0.7, P<0.01).</p><p><b>CONCLUSION</b>The PAFR gene rs5938 or rs313152 polymorphisms might be a potential biomarker for susceptibility to CHD, especially to BSS of CHD in Chinese Han population.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate antimicrobial resistance of Klebsiella pneumoniae and Pseudomonas aeruginosa isolates in fecal samples from rat-like animals.</p><p><b>METHODS</b>Rat-like animals were captured using cages around a hospital and the neighboring residential area between March and October, 2015. K. pneumoniae and P. aeruginosa were isolated from the fecal samples of the captured animals. Antimicrobial susceptibility test was performed according to the guidelines of Clinical and Laboratory Standards Institute (2014).</p><p><b>RESULTS</b>A total of 329 rat-like animals were captured, including 205 Suncus murinus, 111 Rattus norvegicus, 5 Rattus flavipectus and 8 Mus musculus. The positivity rates of K. pneumoniae and P. aeruginosa were 78.4% and 34.7% in the fecal samples from the captured animals, respectively. K. pneumoniae isolates from Suncus murinus showed a high resistance to ampicillin, cephazolin, nitrofurantoin, piperacillin and cefotaxime (with resistance rates of 100%, 51.2%, 44.2%, 37.2%, and 23.3%, respectively), and K. pneumoniae isolates from Rattus spp. showed a similar drug-resistance profile. The prevalence rates of multidrug resistance and ESBLs were 40.9% and 10.7%, respectively. P. aeruginosa from both Suncus murinus and Rattus spp. exhibited the highest resistance rates to aztreonam (12.4% and 16.0%, respectively), followed by penicillins and fluoroquinolones. P. aeruginosa isolates were susceptible to cephems, aminoglycosides and carbapenems (with resistance rates below 5%).</p><p><b>CONCLUSION</b>K. pneumoniae and P. aeruginosa isolated from rat-like animals showed drug-resistance profiles similar to those of the strains isolated from clinical patients, suggesting that the possible transmission of K. pneumoniae and P. aeruginosa between rat-like animals and human beings.</p>

RESUMO

<p><b>OBJECTIVES</b>To investigate the role of prolyl 4-hydroxylase beta polypeptide (P4HB) expressed in lung carcinoma and the intervention effect of Yiqi Chutan Formula (, YQCTF).</p><p><b>METHODS</b>Lung carcinoma model was established by subcutaneously inoculating LEWIS lung carcinoma cells in C57BL/6J mice. The differential expression of P4HB protein between the YQCTF (3.0 g/kg, gavage, once daily, 21 days) group and the control group was acquired by a 2 fluorescence difference gel electrophoresis (2D-DIGE), verified by Western blotting and identified by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/TOF-MS). The expression of P4HB and P4HB mRNA in cultured A549 cells from cisplatin (DDP) 1.5 µg/mL group and 15% serum combined with DDP 1.5 µg/mL group were detected by cellular immunohistochemistry and reverse transcription-polymerase chain reaction, respectively.</p><p><b>RESULTS</b>The proteomics research discovered that one-third of differential proteins including P4HB were decreased in the YQCTF group (P<0.01). Clinical pathology and tissue microarray studies showed that P4HB expression in lung cancer tissue was stronger than adjacent tissues and normal lung epithelial (P<0.01). In the YQCTF and DDP combined groups, the expression of P4HB and P4HB mRNA in A549 cell were decreased significantly (P<0.01).</p><p><b>CONCLUSION</b>YQCTF could inhibit the LEWIS lung carcinoma's growth, decrease the expression of P4HB in LEWIS lung carcinoma and A549 cells. YQCTF might take effect through regulating P4HB in endoplasmic reticulum to inhibit the incidence and growth process of lung carcinoma.</p>

RESUMO

<p><b>OBJECTIVE</b>To evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>A total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.</p><p><b>RESULTS</b>The 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).</p><p><b>CONCLUSION</b>KA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the therapeutic effect of bone marrow mesenchymal stem cells (BM-MSCs) on injured hepatocytes mediated by paracrine mechanisms and to investigate the potential molecular mechanism of this action.</p><p><b>METHODS</b>A contact-independent model of aberrant hepatic microenvironment was established by co-culturing BM-MSCs with D-galactosamine (D-GalN)-injured human L02 hepatic cells using a transwell assay platform. Secreted levels of insulin-like growth factor-1 (IGF-1) were measured by enzyme-linked immunosorbent assay of the co-culture supernatant. Expression of the IGF-1 receptor (IGF-1R) was assessed by Western blot. The effect of exogenous IGF-1 on proliferation of D-GalN-injured L02 cells was examined by MTT assay.</p><p><b>RESULTS</b>Upon co-culture, BM-MSCs promoted proliferation of D-GalN-injured L02 cells in a contact-independent manner (absorbance values of at 24 h: 0.36+/-0.08, 48 h: 0.52+/-0.06, and 96 h: 0.68+/-0.06; vs. uninjured cells t = 2.493, 3.116, and 2.285, respectively; all P less than 0.05). Robust expression of IGF-1 was identified in the supernatants of co-cultures and was demonstrated to have been secreted mainly from BM-MSCs under the influence of D-GalN-injured L02 cells. Constitutive expression of IGF-1R was found in the D-GalN-injured L02 cells and blocking of IGF-1R by a neutralizing antibody significantly inhibited the paracrine pro-proliferative effect of co-cultured BM-MSCs at 24 h, 48 h, and 72 h (t = 2.909, 2.328, and 2.560, respectively; all P less than 0.05).</p><p><b>CONCLUSION</b>BM-MSC-derived IGF-1 plays an important role in the paracrine pro-proliferative effect on D-GalN-injured L02 hepatocytes by engaging with the constitutively expressed IGF-1R on L02 cells.</p>

RESUMO

<p><b>OBJECTIVE</b>To study main factors and the influencing extent of the susceptibility of the Han population with coronary heart disease (CHD) of blood stasis syndrome (BSS) in Fuzhou area.</p><p><b>METHODS</b>A case control study was employed in Fujian People's Hospital from August 2009 to January 2010. Patients with recent attack of CHD of BSS and of CHD of non-BSS, as well as patients without CHD of non-BSS were recruited as subjects. Correlated factors with CHD were collected using questionnaire and laboratory examinations. The correlation and the correlation strength between each factor and CHD of BSS were analyzed using one-way and multiple-factor unconditional Logistic regression methods.</p><p><b>RESULTS</b>Of the 403 patients in line with inclusion criteria, there were 176 patients with CHD of BSS, 123 with CHD of non-BSS, and 104 without CHD of non-BSS. Results of one-way analysis were reported as follows. Senility, mental labors, hypertension, excessive consumption of oil and salt, depression, stress, past relevant medical history, abnormal prothrombin time (PT), and abnormal hematocrit (HCT) were high-risk factors for CHD of BSS. Regular physical exercise and adequate sleep were protective factors. Except for the effects by age and sex, mental labors, hypertension, excessive consumption of oil and salt, depression, stress, past relevant medical history were still risk factors for CHD of BSS, with the correlation strength (OR value, 95% CI) being 1.902 (95% CI 1.222-2.959), 2.221 (95% CI 1.181-4.176), 2.945 (95% CI 1.781 4.871), 1.794 (95% CI 1.114-2.890), 3.462 (95% CI 1.555-7.712), 1.517 (95% Cl 1.082-2.128), and 3.159 (95% CI 1.732-5.764). In the comparison between those with CHD of BBS and those with CHD of non-BBS, excessive consumption of salt and meat, and stress were the risk factors for BSS. After the effects by age and sex were adjusted, the OR value were still 1.586 (95% CI 1.051-2.393), 1.801 (95% CI 1.191-2.723), and 1.386 (95% CI 1.024-1.876).</p><p><b>CONCLUSIONS</b>When compared with the population of non-BSS, the predisposing factors for the Han population with CHD of BSS in Fuzhou area covered mental labors, hypertension, excessive consumption of oil and salt, depression, stress, and past relevant medical history. Compared with other syndrome types in Chinese medicine, positive correlation existed between BSS and excessive consumption of salt and meat, as well as stress.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore Chinese medical syndrome distribution laws in coronary heart disease (CHD) patients of the Han nationality in Fuzhou city.</p><p><b>METHODS</b>A questionnaire on Chinese medical syndrome was carried out in 507 patients with confirmed CHD from different regions of Fuzhou city. The correlation analyses of Chinese medical syndrome distribution laws, the Chinese medical syndrome types and complications, gender, age, the body mass index (BMI) were conducted.</p><p><b>RESULTS</b>Viewed from elements of deficiency in origin or excess in superficiality, blood stasis syndrome was the most often seen syndrome in patients with CHD (accounting for 63.1%), followed by qi deficiency syndrome (accounting for 59.4%) and phlegm turbidity syndrome (accounting for 45.6%). Among syndrome types, qi deficiency blood stasis syndrome was the most often seen syndrome (accounting for 12.2%), followed by qi deficiency, blood stasis and phlegm turbidity syndrome (accounting for 9.1%), and qi deficiency and phlegm turbidity syndrome (accounting for 8.1%). The distribution of various Chinese medical syndrome types showed significant difference in different ages (P<0.05), but no obvious difference was shown in different genders, body mass index, or complications (P>0.05).</p><p><b>CONCLUSIONS</b>Blood stasis, qi deficiency, and phlegm turbidity were the basic pathogeneses of CHD patients of the Han nationality in Fuzhou city. Syndrome with intermingled blood stasis, qi deficiency, and phlegm turbidity was the main Chinese medical syndrome pattern. The combination of syndrome showed certain regularity.</p>

RESUMO

<p><b>OBJECTIVE</b>To obtain the functional information of AY358935 gene.</p><p><b>METHODS</b>The properties, subcellular location, and structure of AY358935 protein, and the expression profile of AY358935 gene were analyzed by bioinformatics software and the biological functions of the gene were predicted. AY358935 expression was detected by Western blot analysis in early virus infection.</p><p><b>RESULTS</b>AY358935 was evolutionally conserved. The human AY358935 protein had an amino acid similarity of 74%, 60%, 38% and 33% with its counterpart in horses, mice, zebrafish and Xenopus laevis, respectively. Bioinformatics analysis indicated that AY358935 protein was located likely in the mitochondria. There was a N-terminal signal peptide and single transmembrane structure in AY358935 protein, which contained several phosphorylation sites. The secondary structure mainly comprised of alpha helices and random coils. AY358935 was ubiquitously expressed in normal tissues and carcinomas and regulated by the expression of double-stranded RNA-dependent protein kinase. AY358935 protein expression was obviously upregulated in cells 2 h after infection by vesicular stomatitis virus.</p><p><b>CONCLUSION</b>As a predicted secretary protein with a small molecular weight, AY358935 might have important functions in cellular proliferation and anti-viral innate immune regulation.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the apoptosis inducing effects of Hechanpian (HCP) on human lung adenocarcinoma A549 cells.</p><p><b>METHODS</b>HCP containing rat serum was prepared and applied on A549 cells. The cell growth inhibition rate was tested by MTT assay; the effect of HCP on cell apoptosis was observed with Propidium iodide (PI) staining and flow cytometry analysis; the mRNA expression of epidermal growth factor receptor (EGFR) was detected through RT-PCR.</p><p><b>RESULTS</b>The growth of A549 cells was obviously inhibited after being treated by HCP containing serum, and the cells presented an apoptotic change. The cell apoptosis rate after treated by serum containing 10% and 20% HCP was 20.5% and 33.2%, respectively, significantly higher than that in the control (6.1% in cells didn't treated with HCP, P < 0.05). Compared with control, EGFR mRNA expression in HCP treated cells was significantly lower (P < 0.05).</p><p><b>CONCLUSION</b>HCP has apoptosis inducing effect on A549 cell, and its molecular mechanism is probably correlated with the inhibition of EGFR gene transcription.</p>

RESUMO

Proteomics plays important roles in Chinese medicine research at post-genomics era. Its research idea and methods are beneficial for elucidating some elemental features of Chinese medicine. At present, Chinese medicine proteomic studies are mainly focusing on the syndromatology and medical herbal pharmacology. However, there are still some problems, the most important matter was that most of the results were merely the superficial delineations. Further research should put emphasize on the unremitting and penetrating study of proteomics, molecular biology and bioinformatics integrally for illuminating Chinese medicine theory deeply to promote the modernization of Chinese medicine research.

RESUMO

Despite Salvia miltiorrhiza being one of the most important medicine plants in China, there is a limited availability of genomic resources, especially of the expressed sequence tag-based markers. In this study, we selected and characterized functional markers in S. miltiorrhiza, which consisted of 4,192 non-redundant expressed sequence tags (ESTs) from 10,288 identified S. miltiorrhiza ESTs in dbEST data bank. Among them, 159 simple sequence repeats (SSR) were detected, which amounted to 3.79% of the non-redundant starting sequence population. This incidence was equivalent to one EST-SSR in every 12.74 kb of S. miltiorrhiza ESTs. Among the different motifs ranging from 1 bp to 6 bp, di-nucleotide repeat motif was the most abundant (77, 48.43%), followed by tri-nucleotide (41, 25.79%), hexa-nucleotide (23, 14.47%), penta-nucleotide (12, 7.55%) and tetra-nucleotide (6, 3.77%). In 47 identified motif types, the detected frequency above 5% were GA/CT (16.35%), AG/TC (15.09%), TCA/AGT (10.69%), AT/TA (6.29%), GAAAAG/CAAAAC (6.29%) and TA/AT (5.03%). Based on flank sequence of detected SSR, a total of 83 EST-SSR primer pairs were designed and tested for the amplification efficiency, polymorphism and transferability in thirteen S. mihiorrhiza samples and other ten species from the genus Salvia. The results showed that 72 primer pairs were successfully amplified in S. miltiorrhiza samples to yield and 279 loci with an average of 3.88 loci per primer pair. The cross-transferability of S. miltiorrhiza EST-SSR markers to other ten Salvia plants was very high, ranging from 60% to 100% with an average of 85%. Further analysis of the genetic similarity based on the polymorphic bands showed the EST-SSR could detect the genetic diversity on different levels among the whole test samples and distinguish the S. miltiorrhiza from other Salvia plants effectively. It is expected that the potential markers described here would add to the repertoire of DNA markers needed for genetic analysis, linkage mapping and comparative genomics studies in S. miltiorrhiza and related Salvia genus plants.
