RESUMO
Objective To investigate the need for and utilization of health services among six Zhiguo ethnic minority groups in Yunnan Province,aiming to provide further evidence for the improvement of healthcare.Methods Using stratified random sampling,1921 individuals from six Zhiguo ethnic minority groups,aged 15 and above,were investigated with a structured questionnaire between August and December 2022.A structured questionnaire was used to collect participants'information on health service needs and utilization.Results Am-ong the surveyed participants,the two-week prevalence rate was found to be 22.54%,while the prevalence rate of chronic diseases was 38.52%.Among the residents,the risk of two-week prevalence was higher for females(OR=1.564),individuals aged≥60 years(OR=1.727),and those who reported poorer health utility value(OR=5.277),while it was lower for residents of Keno(OR=0.470)and Lahu(OR=0.659)ethnicity,as well as those who reported higher EQ-VAS scores(OR=0.446/0.174).Meanwhile,residents aged≥45 years(OR=3.392/7.072)were at higher risk for chronic disease prevalence,while it was lower for Keno ethnicity(OR=0.409),unmarried individuals(OR=0.479),and those with higher education levels(OR=0.629/0.603),higher EQ-VAS scores(OR=0.208)P<0.05.Additionally,among the participants,the treat-ment rate for two-week illness was 14.32%,while the non-treatment rate stood at 36.49%.Furthermore,the one-year hospitalization rate was reported as 19.89%,with a corresponding rate of individuals who needed hospitalization but did not receive it being recorded at 15.86%.Among the residents,the likelihood of treatment for two-week illness was higher for females(OR=1.461)and residents aged≥45 years(OR=1.510/1.560),whereas it was lower for individuals with higher EQ-VAS scores(OR=0.445).The likelihood of hospitalization within one year was also higher for residents aged≥60 years(OR=2.029)and individuals of Nu(OR=1.599),Lisu(OR=1.688),and Keno(OR=1.968)ethnicity,whereas those with high EQ-VAS scores(OR=0.325)had a lower risk(P<0.05).Conclusion In Yunnan Province,the need for healthcare services among six Zhiguo ethnic minority groups in this study is relatively low;however,the high prevalence of chronic diseases raises concerns.The utilization of healthcare services appears to be relatively sufficient,but the utilization of outpatient services still needs to be improved.
RESUMO
COVID-19 associated Guillain-Barré syndrome (GBS) caused by peripheral nerve damage after SARS-CoV-2 infection is one of the most common COVID-19 related nervous system inflammatory diseases, with high incidence of respiratory failure and mortality. Positive SARS-CoV-2 RNA in cerebrospinal fluid of COVID-19 associated GBS patients has been rarely reported. This paper reports 4 patients with COVID-19 associated GBS in China who developed neurological symptoms 4-15 days after fever and were confirmed SARS-CoV-2 infection. All patients presented with progressive weakness of both lower limbs, 3 patients with autonomic dysfunction such as defecation and urination disorders, and 1 patient with polycranial neuritis and Miller-Fisher syndrome such as bilateral facial palsy, dysphagia, diplopia and ataxia. Nerve conduction velocity and F wave were abnormal in 3 patients, and motor conduction pathway was abnormal in 1 patient. Anti-ganglioside antibodies were tested in 3 patients, and GD1a-IgG was positive in 1 patient. All 4 patients underwent metagenomic next-generation sequencing examination in blood and cerebrospinal fluid. SARS-CoV-2 RNA was positive in blood and cerebrospinal fluid of 3 patients, and SARS-CoV-2 RNA was positive in cerebrospinal fluid of 1 patient.
RESUMO
Breast cancer is a kind of malignant tumor with high heterogeneity.Chemotherapy is one of the important treat-ments for advanced breast cancer or postoperative breast cancer.However,the emergence of secondary drug resistance weakens the ef-fectiveness of chemotherapy,leading to a poor prognosis for patients.In recent years,more and more studies have shown that non-coding RNA(ncRNA)can promote breast cancer chemotherapy resistance by regulating cell proliferation,tumor stem cell characteris-tics,epithelial-mesenchymal transition and other processes.This article reviews the research on the mechanism of ncRNA-mediated chemotherapy resistance in breast cancer.
RESUMO
Non-coding RNAs (ncRNAs) are a class of functional RNAs that play critical roles in different diseases. NcRNAs include microRNAs, long ncRNAs, and circular RNAs. They are highly expressed in the brain and are involved in the regulation of physiological and pathophysiological processes of central nervous system (CNS) diseases. Mounting evidence indicates that ncRNAs play key roles in CNS diseases. Further elucidating the mechanisms of ncRNA underlying the process of regulating glial function that may lead to the identification of novel therapeutic targets for CNS diseases.

Methods:The retrospective cohort study was conducted. The clinicopathological data of 262 patients with gastric cancer who were admitted to the 940th Hospital of Joint Logistic Support Force of Chinese People′s Liberation Army from January 2016 to January 2019 were collected. There were 214 males and 48 females, aged (58±11) years, with a range from 17 to 81 years. Of 262 patients, 120 cases undergoing Da Vinci robotic-assisted total gastrectomy + D 2 lymphadenectomy + Roux-en-Y anastomosis were divided into robotic group, and 142 cases undergoing laparoscopic-assisted total gastrectomy + D 2 lymphadenectomy + Roux-en-Y anastomosis were divided into laparoscopic group. Observation indicators: (1) intraoperative and postoperative situations; (2) postoperative pathological examination; (3)complications; (4) stratified analysis; (5) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect complications, tumor recurrence and survival of patients within postoperative 2 months. The follow-up was up to May 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability.

RESUMO
Objective@#To investigate the effect of long-chain non-coding RNA Fez family zinc finger protein 1 antisense RNA1 (lncRNA FEZF1-AS1) on the biological function of hepatocellular carcinoma (HCC).@*Methods@#SMMC771 and BEL-7402 cells were transfected with sh-FEZF1-AS1 and OE-FEZF1-AS1, respectively. The expression of lncRNA FEZF1-AS1 was detected by real-time quantitative PCR. Cell proliferation was detected by Cell Counting Kit-8 (CCK-8), and apoptosis was detected by flow cytometry. The effects of lncRNA FEZF1-AS1 on invasion and migration were detected by Transwell and wound healing assays. The expression levels of adhesion molecules were detected by Western blot. The effect of lncRNA FEZF1-AS1 on the in vivo growth was verified by nude mice xenograft experiments.@*Results@#The silencing or ectopic expression of lncRNA FEZF1-AS1 inhibited or promoted the proliferation of hepatocellular carcinoma cells. CCK-8 assay showed that the proliferation abilities of SMMC7721 and BEL-7402 cells in sh-FEZF1-AS1 transfection group significantly decreased, achieving (35.43±4.06)% and (34.68±3.97)%, respectively, on the fifth day. There were significant differences between sh-FEZF1-AS1 group and sh-NC group [52.21±8.46)% and (53.76±7.64)%] (all P<0.05). In contrast, the proliferation ability of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 was significantly increased, achieving (83.49±6.92)% and (80.31±3.13)%, respectively, on the fifth day. There were significant differences between OE-FEZF1-AS1 and OE-NC group [53.03±8.84)% and (55.11±7.09)%] (all P<0.05). The subsequent flow cytometry results showed that cell apoptotic rates of SMMC7721 and BEL-7402 cells transfected with sh-FEZF1-AS1 were (13.02±1.38)% and (11.88±1.29)%, respectively, which were significantly higher than those in sh-NC groups [(5.57±1.46)% and (8.06±1.42)%, respectively, all P<0.05]. In contrast, the apoptotic rates of SMMC7721 and BEL-7402 cells transfected with OE-FEZF1-AS1 were (3.01±0.39)% and (3.22±0.43)%, which were significantly lower than those in OE-NC groups [(6.68±0.96)% and (6.63±0.45)%, all P<0.05]. In addition, knockdown or overexpression of lncRNA FEZF1-AS1 expression inhibited or enhanced the migration and invasion abilities as well as the levels of adhesion molecules in hepatocellular carcinoma cells. After 30 days of feeding under the same conditions, the tumor volumes of sh-FEZF1-AS1 and sh-NC SMMC7721 cells xenograft mice models were (0.26±0.03) cm3 and (0.63±0.06) cm3, respectively, showing significant difference (P<0.05). The tumor volumes of sh-FEZF1-AS1 and sh-NC BEL-7402 cells were (0.31±0.02) cm3 and (0.72±0.08) cm3, and the difference was statistically significant (P<0.05).@*Conclusion@#lncRNA FEZF1-AS1 may strengthen the growth, migration and invasion of hepatocellular carcinoma cells.
RESUMO
Objective To compare metabolic syndrome(MS)with Framingham risk score as predictors of cardiovascular disease( CVD) among Kazakhs. Methods The participants were the residents who had been followed up for more than 5 years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting years in representative areas of Kazakhs in Xinjiang. We assigned MS a continuous risk score for predicting the development of CVD based on the weights of MS components. MS and Framingham risk score were compared in terms of their ability in predicting development of CVD using Cox regression and receiver operating characteristic curve. Results The incidence of CVD was 13.87%. The incidence of CVD was higher in the MS group than it in the non-MS group(21.59% vs 11.10%, P<0.001). The area under the receiver operating characteristic(ROC)curve of MS risk score was significantly larger than that of MS classification(0.727 vs 0.585, P<0.001);the area under the curve of MS risk score was close to that of Framingham risk score ( 0. 732 vs 0.727, P=0.673). The association between CVD and each quintile of MS risk score was more significant than that between Framingham risk score and CVD under the same exposed condition(4.61、9.33、14.15、22.29对3.69、6.36、8.47、16.99) . Conclusion MS risk score that included age may be a better predictor of CVD among Kazakhs.

The scores of NIH-CPSI and leukocyte count in both groups were significantly lower after treatment (P<0.01), and those in observation group weresignificantly lower than those in control group (P<0.01). The cases with lecithin corpuscles++++in both groups were significantly more after treatment (P<0.01), and those in observation group were significantly more than those in control group (P<0.01). The peak flow rate and mean flow rate in both groups were higher after treatment (P<0.01), and it was higher in observation group (P<0.01). Conclusion The efficacy of Dahuang Xiaozhi Suppository in treating CABP/CPPS of moist heat and blood stasis syndrome is remarkable, and it is better than Qianliean Suppository.
RESUMO
Objective To investigate the correlation between prognosis of patients with severe acute pancreatitis and changes of plasma albumin. Methods A total of 235 patients with severe pancreatitis who were admitted into hospital from September 2008 to October 2013 were selected as research object. According to the prognosis, they were divided into the survival group (143 cases who were recovered and still alive) and the death group (92 cases who died of the deterioration of diseases). Retrospectively analyzed the basic situation of the pa-tients and the changes of serum albumin levels in the two groups. And the correlation between prognosis of patients with severe acute pancrea-titis and changes of plasma albumin were evaluated by the logistic regression analysis. Results Compared with the death group,there were significant differences (P<0. 05) in terms of age,APCHEⅡ score,Ranson score,SOFA score,length of hospital stay,duration of mechani-cal ventilation,continuous renal replacement therapy,average serum albumin level,decrease of serum albumin within 24 hours,and variation of serum albumin. And ROC curves suggested the best cutoff value of decrease of serum albumin within 24 hours to predict death in patients within 24 hours was 4. 24 g/L,and the best cutoff value of variation of serum albumin to predict death was 13. 6%. Logistic regression analy-sis showed that the major risk factors of death in severe acute pancreatitis were decrease of serum albumin within 24 hours,variation of serum albumin within 24 hours,average serum albumin level,and the APCHEⅡscore. Conclusion Changes in plasma albumin can reflect the se-verity of severe acute pancreatitis,and the sharp decrease of serum albumin within 24 hours can be used as a risk factor for death.

The control group received the treatment of tamsulsosin hydrochloride capsules, 0.2 mg/d, qn, and the observation group received the treatment of traditional Chinese medicine retention-enema additionally. The course was 4 weeks. The clinical effects of the two groups were observed and compared. The indexes including the scores of NIH-CPSI, leukocyte count and lecithin corpuscles in prostatic fluid, urinary flow rate were evaluated. Results The total effective rate was 100%(100/100) in observation group, and 88% (88/100) in control group. There was significant difference between the two groups (P0.05). Conclusion Traditional Chinese medicine retention-enema combined with tamsulsosin hydrochloride capsules can significantly improve the clinical effect of CABP/CPPS.
RESUMO
<p><b>OBJECTIVE</b>To observe the variations of intracellular localization and expression of importin 8 (IPO8) during osteoblast differentiation.</p><p><b>METHODS</b>Alizarin red staining, immunocytochemistry and real-time PCR were employed to examine the changes in the intracellular localization and expression of IPO8 mRNA during induced osteogenic differentiation of human osteoblast-like SaOS-2 cells.</p><p><b>RESULTS</b>Numerous red mineralized nodules were observed on day 10 in the induced cells with alizarin red staining. Immunocytochemical staining showed that IPO8 immunoreactivity was the strongest in the perinuclear cytoplasm of the cells. On day 3 of osteoblast differentiation, IPO8 immunoreactivity in the cell nuclei became stronger. On day 7, IPO8 was located mainly in the nuclei, and on day 10 the cells were osteocyte-like and IPO8 was distributed in the cytoplasm. Real-time PCR showed a significantly increased expression of OPN mRNA during osteoblast differentiation, and the expression level of IPO8 mRNA was the highest on day 3 and declined on days 7 and 10.</p><p><b>CONCLUSION</b>The intracellular localization and expression level of IPO8 undergo significant changes during osteogenesis, indicating its role in regulating osteoblast differentiation.</p>

Objective To investigate the suppression of mrp1 and MRP1 induced by small interfering RNA and the restoration of sensitivity to chemotherapeutic drugs in the multidrug-resistant hepatocellular carcinoma cell lines HepG2/mrp1. Methods mrp1-targeted small interfering RNA duplexes were designed and composed and introduced into multidrug-resistant hepatocellular carcinoma cell lines HepG2/mrp1. The suppression of mrp1 mRNA and its gene product MRP1 was examined by RT-PCR and flow cytometry (FCM), respectively. MTT assay was performed to measure the reverse effect of small interfering RNA based on the results of ICs0. Results The overexpression of mrp1 mRNA and MRP1 was effectively suppressed by small interfering RNAs. The level of mrp1 mRNA in the transfected HepG2/mrp1 cells was reduced to (86.36±2.76)% and MRP1 to (89.38±3.76)%compared with those of the controls. The resistance to ADR was reversed five-fold, which indicated the restoration of sensitivity to drugs. Conclusion Small interfering RNA can inhibit mrp1 expression effectively and reverse the multidrug resistance mediated by MRP1.
RESUMO
BACKGROUND:Previous in vitro studies mainly focused on morphological and nerve marker aspects in the study of bone marrow mesenchymal stem cells (BMSCs)-derived neuron-like cells,but less focused on the olectrophysiological properties of neuron-like cells following differentiation.OBJECTIVE:To study the electrophysiological changes of differentiation from BMSCs into neuron-like cells after induction by brain-derived neurotrophic factor (BDNF)/basic fibroblast growth factor (bFGF)/alltrans-retinolc acid (AT-RA).DESIGN,TIME AND SETTING:The cytological comparative in vitro study was performed at the Department of Neural Cell Laboratory,Tianjin Huanhu Hospital and College of life Science of Nankai University from June 2005 to October 2007.MATERIALS:Totally 3 male Wistar rats (6-week old,weighing about 160 g) were used in this study.METHODS:BMSCs were cultured and purified by their characteristic of plastic adhesion in vitro,and then induced by BDNF,bFGF and AT-RA,and differentiate into neuron-like cells.Whole-cell patch damp technique was used to detect cell membrane current prior to and 3 days following induction.MAIN OUTCOME MEASURES:MSC phenotype was determined by flow cytometry.Cell morphology was observed under the inverted microscope before and after differentiation.Neuron specific enolase expression was assessed by immunocytochemistry.Whole-cell current results were measured.RESULTS:Flow cytometry results demonstrated that CD90 positive rate (99±3)%,CD31 (3.4±0.8)%,and CD34 (0.3±0.1)%.This indicated that these cells were undifferentiated stem cells,with purity of 95%.Undifferentiated MSCs under the optical microscope were mostly fiat cells with processes,similar to fibroblast-like cells.Neuron-like cells appeared 3 days following induction.Immunocytochemistry results showed that MSCs before induction were weakly positive for neuron specific enolase,but strongly positive for neuron specific enolase.At 72 hours,the differentiated rate was (24.01±3.76)%.The peak currents of outward currents in neuron-like cells were significantly higher in the induction group compared with the control group (P < 0.05),but no inward Na~+ current was detected.CONCLUSION:(bFGF & BDNF)/AT-RA could induce the differentiation of MSCs into neuron-like cells.These cells showed the tendency to differentiate into mature neurons,though having no electrophysiological properties of mature neurons.
