RESUMEN
BACKGROUND: COVID-19 poses great challenges for preschool teachers in China, which will increase the level of job stress and job burnout, and have an impact on the relationship between job stress, job burnout, and perceived organizational support (POS). However, few studies have examined trilateral relationships, especially the role of POS concerning job stress and job burnout of preschool teachers. OBJECTIVE: This study aimed to investigate the relationship among the three variables of job burnout, job stress, and POS, as well as explore the moderating effects of POS between job stress and job burnout. METHODS: A cross-sectional study was conducted among preschool teachers in six provinces of China. A total of 408 preschool teachers completed a self-report questionnaire, including three scales that measured job burnout, job stress, and POS respectively. The Pearson correlation coefficient and regression analysis were used to examine the relationship among variables. RESULTS: The results showed that job burnout among Chinese preschool teachers was at a medium level during the COVID-19 pandemic. Job stress was positively related to job burnout, and the POS was negatively related to job burnout. Additionally, POS moderated the relationship between job stress and job burnout and alleviated the adverse effects of job stress on the job burnout of preschool teachers. CONCLUSION: POS can play a moderating role between job stress and job burnout of Chinese preschool teachers during the COVID-19 pandemic.

Objective To investigate the clinical effect of duloxetine in the treatment of functional gas-trointestinal disorders(FGIDs).Methods Seventy-eight patients with FGIDs treated in this hospital from March 2020 to July 2022 were selected as the research subjects.The patients with the self-rating anxiety scale(SAS)score ≥50 points and self-rating depression scale(SDS)score ≥53 points were divided into the control group and observation group according to block randomization,39 cases in each group.The control group was treated with routine internal medical treatment,and the observation group was treated with duloxetine on the basis of the control group.The course of treatment in the two groups was one month.The psychological sta-tus,gastrointestinal symptoms and adverse reactions before and after treatment were compared between the two groups.Results After treatment,the scores of SAS,SDS and gastrointestinal symptom rating scale(GSRS)in the two groups were lower than those before treatment,those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).There were 8 ca-ses(20.51%)of adverse reactions in the control group and 7 cases(17.95%)in the observation group,and the difference was not statistically significant(P>0.05).No liver and kidney function abnormalities and uri-nary tract systematic diseases were found in both group.Conclusion Duloxetine is effective in the treatment of FGIDs,which could improve the clinical symptoms and psychological symptoms of the patients,and the medication is safe.
RESUMEN
ObjectiveTo investigate the serum level of 25-hydroxyvitamin D in patients with nonalcoholic fatty liver disease (NAFLD) and obesity, as well as the correlation of 25-hydroxyvitamin D with liver function, blood lipids, and inflammatory indicators. MethodsA total of 90 patients with NAFLD who attended Shanxi Bethune Hospital from January 2022 to March 2023 were enrolled, and according to the body mass index (BMI), they were divided into NAFLD+obesity group with 60 patients (BMI≥28 kg/m2) and NAFLD group with 30 patients (BMI<28 kg/m2); 30 individuals who underwent physical examination during the same period of time were enrolled as control group. Related indications were measured for all three groups, including serum 25-hydroxyvitamin D, liver function parameters (alanine aminotransferase [ALT], aspartate aminotransferase [AST], alkaline phosphatase [ALP], gamma-glutamyl transpeptidase [GGT], total bilirubin [TBil], and direct bilirubin [DBil]), blood lipid parameters (high-density lipoprotein [HDL], low-density lipoprotein [LDL], total cholesterol [TC], and triglyceride [TG]), inflammatory indicators (high-sensitivity C-reactive protein [H-CRP] and Golgi protein 73 [GP-73]), cytokines (interleukin-2 [IL-2], interleukin-4 [IL-4], interleukin-6 [IL-6], interleukin-10 [IL-10], interleukin-17 [IL-17], interleukin-1β [IL-1β], tumor necrosis factor-α [TNF-α], and interferon gamma [IFN-γ]), and liver/spleen volume ratio. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test or the Tamhane’s T2 test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. A Pearson or Spearman correlation analysis was performed. ResultsCompared with the control group, the NAFLD+obesity group had significant reductions in 25-hydroxyvitamin D, HDL, cytokines (IL-2, IL-4, IL-10, and IFN-γ), and liver/spleen volume ratio (all P<0.05), as well as significant increases in liver function parameters (ALT, AST, ALP, GGT, TBil, and DBil), blood lipid parameters (LDL, TC, and TG), inflammatory indicators (H-CRP and GP-73), and cytokines (IL-1β, IL-17, and TNF-α) (all P<0.05). There were significant differences between the NAFLD+obesity group and the NAFLD group in all the above indicators except liver/spleen volume ratio and H-CRP (all P<0.05). The correlation analysis showed that 25-hydroxyvitamin D level was negatively correlated with ALT (r=-0.324, P=0.012), AST (r=-0.421, P=0.001), ALP (r=-0.435, P=0.001), GGT (r=-0.343, P=0.007), TBil (r=-0.532, P<0.001), DBil (r=-0.521, P<0.001), LDL (r=-0.405, P=0.001), TC (r=-0.466, P<0.001), TG (r=-0.551, P<0.001), H-CRP (r=-0.434, P=0.014), GP-73 (r=-0.421, P=0.001), IL-1β (r=-0.433, P=0.001), IL-17 (r=-0.465, P<0.001), and TNF-α (r=-0.533, P<0.001), and it was positively correlated with HDL (r=0.632, P<0.001), IL-2 (r=0.546, P<0.001), IL-4 (r=0.533, P<0.001), IL-10 (r=0.456, P<0.001), and liver/spleen volume ratio (r=0.543, P<0.001). ConclusionSerum 25-hydroxyvitamin D is significantly correlated with liver function parameters, blood lipid parameters, and inflammatory indicators in patients with NAFLD and obesity, and it may alleviate the symptoms of patients with NAFLD and obesity by reducing inflammatory response, which provides new intervention strategies for the treatment of NAFLD.
RESUMEN
Objective To investigate the predictive value of serum matrix metalloproteinase-9(MMP-9)and soluble triggering receptor expressed on myeloid cells-1(sTREM-1)in postoperative urinary tract infec-tion(UTI)in patients with ureteral calculi.Methods Among the ureteral calculi patients admitted to the De-partment of Urology in a hospital from October 2021 to October 2022,68 patients with postoperative UTI(UTI group)and 68 patients without UTI(non-UTI group)were selected as the study objects.Serum MMP-9 and sTREM-1 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman method was used to analyze the correlation between serum MMP-9 and sTREM-1 levels and clinical data in UTI group,and the predictive value of serum MMP-9 and sTREM-1 levels in postoperative UTI in ureteral calculi patients was analyzed by receiver operating characteristic curve.The influencing factors of postoperative UTI in ureter-al calculi patients were analyzed by multivariate Logistic regression.Results Compared with non-UTI group,serum MMP-9 and sTREM-1 levels in UTI group were significantly increased,with statistical significance(P<0.05).Correlation analysis showed that serum MMP-9 and sTREM-1 levels were positively correlated in UTI group(r=0.585,P<0.001).The combined prediction of the area under the curve(AUC)for postopera-tive UTI in ureteral calculi patients was 0.961(95%CI:0.934-0.988).The sensitivity and specificity were 73.36%and 85.68%,respectively.The AUC predicted by MMP-9 and sTREM-1 was higher than that predic-ted by MMP-9 and STREM-1 alone(Z=25.420,P<0.001;Z=21.531,P<0.001).The levels of MMP-9 and sTREM-1 were the influencing factors of postoperative UTI in ureteral calculi patients(P<0.05).Conclusion The serum levels of MMP-9 and sTREM-1 in postoperative UTI in ureteral calculi patients are increased,and the detec-tion of both levels has important predictive value for the occurrence of postoperative UTI in ureteral calculi patients.
RESUMEN
Objective:To investigate the relationship between the age-adjusted Charlson comorbidity index(aCCI)and the risk of in-hospital death for people aged ≥ 90 years with community-acquired pneumonia(CAP), and to construct a novel scoring model for predicting in-hospital mortality.Methods:Basic personal and medical data about sex, age, hospitalization days, hospitalization expenses, in-hospital outcomes and discharge/admitting diagnosis of CAP patients aged ≥ 90 years hospitalized in Peking University Third Hospital between 2010 and 2019 were collected retrospectively.Multivariate Logistic regression analysis was conducted to examine the association between aCCI or other complications and in-hospital death.The receiver operating characteristic curve(ROC)was used to assess the value of aCCI and a new scoring model in predicting in-hospital death of CAP in people aged ≥ 90 years.Results:A total of 274 CAP patients aged ≥ 90 years were included in this study, of whom 85 died in hospital.Multivariate Logistic regression analysis showed that malnutrition( OR=2.21, 95% CI: 1.05-4.67, P<0.05), respiratory failure( OR=18.91, 95% CI: 9.34-38.25, P<0.001)and aCCI( OR=1.51, 95% CI: 1.23-1.85, P<0.001)were prognostic factors for in-hospital death in CAP patients aged ≥ 90 years.Based on the above results, a novel scoring model, MRC(malnutrition, respiratory failure, aCCI)was established.The area under the ROC curve of the aCCI score for predicting the risk of in-hospital death in CAP patients aged ≥ 90 years was 0.743(95% CI: 0.684-0.802). The area under the ROC curve of the MRC score was 0.891(95% CI: 0.848-0.933), indicating a higher predictive value than that of the aCCI score alone( Z=6.337, P<0.001). Conclusions:The MRC score model can be used to evaluate and predict the risk of in-hospital death in long-living CAP patients.
RESUMEN
Objective To investigate the relationship between postoperative cochlear implant electrade inser-tion depth,the scalar localization of cochlear electrode,cochlear size and coiling pattern,and the factors influencing the postoperative electrode implantation depth and the reasons of dislocation.Methods A total of 41 cases of pa-tients implanted with electrode of SONATA ti100 Standard and 30 cases of patients with CI24RE(CA)modilar elec-trode were studied.Postoperative insertion length,insertion depth angle of cochlear electrode,and the scalar locali-zation of cochlear electrode were measured.The relationships of the above factors and the parameters of cochlear size,cochlear length,tilt angles collectal via CT scan preoperatively were analyzed.Results ① The measurement results showed the insertion depth angle and liner insertion length varied greatly among individuals.The mean inser-tion depth angle was 702±53 degrees and the mean liner insertion length was 30.02±1.29 mm in the group of SO-NATA ti100 Standard.The mean insertion depth angle was 441±45 degrees and the mean liner insertion length was 18.4±1.0 mm in the group of CI24RE(CA).② The length and width of cochlear base both had negative corre-lations with the insertion depth angle in the two groups[SONATA ti100 Standard:r=-0.768,P<0.001 & r=-0.678,P<0.001;CI24RE(CA):r=-0.467,P=0.008 & r=-0.471,P=0.008].The liner insertion length of the electrode had a positive correlation with the insertion depth angle in the two groups[SONATA ti100 Standard:r=0.578,P<0.001;CI24RE(CA):r=0.748,P<0.001].③ 6 cases of modiolar electrode were dislo-cated and the site of the dislocation was at 180 degrees of cochlea.The tilt angle within the first turn of cochlea and angle between the first and second turn of cochlea had significant differences between the group of patients with dis-location and without dislocation(10.28 degrees vs 8.75 degrees,P=0.006;15.25 degrees vs 14.00 degrees,P=0.033).Conclusion The insertion depth angle and the insertion length of electrode varied greatly among individu-als.These differences are related to the cochlear size.The difference in cochlear coiling pattern is one of the reasons for dislocation of electrode.
RESUMEN
BACKGROUND:Poor incision healing and infection often occur in elderly patients with lateral malleolar fractures after traditional lateral plate fixation.With the application of engineering software in medicine,a new type of plate placed posterolateral can be designed to solve the above-described problems. OBJECTIVE:To design a new type of posterior lateral low-profile steel plate with the aid of medical bioengineering software,based on the 3D CT data of the distance between the top of the lateral ankle fracture line to the anterior starting point(ACD),the distance between the top of the fracture line to the tip of the lateral ankle(CTD),the distance between the top of the fracture line to the posterior edge of the fracture line(PCD)and the angle between the anterior and posterior lateral sides of the distal fibula(CA). METHODS:Thirty cases of unstable lateral malleolar fracture and normal ankle were taken for CT scanning and three-dimensional reconstruction.The ACD,CTD,and PCD values in patients with lateral malleolar fracture were measured by 3-matic software,and the characteristics of lateral malleolar fracture line were plotted and described.The mimics software was used to measure the value of CA in the normal ankle joint.Based on the data measured above,3-matic software and solidworks software were used to design the low-profile steel plate and the thickness of the steel plate and the direction of the nail path were constructed.In Geomagic Studio software,fine surface,automatic surface,and fitting surface were used to generate the prototype of the low-profile steel plate,and then 3D printing was performed.After making a posterolateral incision of the lateral malleolus,the peroneus longus and brevis tendons were removed,and the prototype of the 3D-printed steel plate was placed behind the fibula to test its size and fit to the bone surface. RESULTS AND CONCLUSION:(1)The mean of ACD was(2.97±0.03)cm,and the variation was 5.23.The mean of PCD was(3.17±0.11)cm,and the variation was 17.60.The mean of CTD was(4.52±0.07)cm,and the variation was 8.60.(2)The fracture line of the lateral malleolus was drawn with an inverted"V"shape.The mean of CA between anterior and posterior lateral surfaces of the distal fibula was(103.20±1.94)°.At the midpoint section of the upper and lower vertices of the anterior edge of the distal fibula,the angle of the anterior and posterior lateral sides(CA)of the distal fibula was(78.50±1.78)°.(3)By using 3-matic,Solidworks,and Geomagic Studio software,a new type of posterior lateral low-profile steel could be successfully designed.Three to four holes were reserved for the screw holes at the proximal end of the plate with screw directions from back to front,and three screw holes were reserved on the inner and outer sides at the far end.The direction of the inner three holes could be from back to front,and the outer three screw holes needed to be biased towards the inner side,with an angle of 9.72°-13.28°.(4)It is indicated that the variability of the ACD position on the anterior lateral fracture line of the lateral malleolus is relatively small,while the variability of the posterior lateral PCD position is relatively large.The angle between the anterolateral and posterolateral sides of the lateral ankle fracture block shows a decreasing trend,with a smaller variation in the proximal angle and a larger variation in the distal angle.Based on three-dimensional CT reconstruction data of the external ankle,with the help of computer bioengineering software and the use of reverse design concept,a new type of low-profile lateral malleolus steel plate with a good fit can be quickly and conveniently designed to provide a valuable reference for the design of internal fixation devices.

RESUMEN
AIM:To observe the accuracy of infiltrating B ultrasound guided A-scan segment biometric measurement of axial length in dense cataract.METHODS: Perspective study. A total of 86 patients(90 eyes)with dense cataract were selected from Chengdu Aier Eye Hospital from August 2020 to August 2022. There were 61 males(59 eyes)males and 25 females(31 eyes)females, with an average age of 66.49±14.55 years. The axial length(AL), anterior chamber depth(ACD)(including corneal thickness), corneal curvature(K), lens thickness(LT), central corneal thickness(CCT), and white-to-white(WTW)were measured preoperatively by contact A-scan, infiltrating B ultrasound guided segmented A-scan, and IOL Master 700, respectively. At 1 wk postoperatively, AL was retested by IOL Master 700 in aphakic mode. Furthermore, the agreements and correlations of AL obtained by the three kinds of devices were analyzed.RESULTS:The AL measured by contact A-scan and infiltrating B ultrasound guided segmented A-scan were 23.40(22.63, 23.89)mm and 23.70(23.04, 24.25)mm, respectively, and the AL measured by IOL Master 700 at 1 wk postoperatively was 23.72(23.01, 24.27)mm. There were statistical significant difference in AL measured by the three methods(P=0.018), while there were no statistical significant difference in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.991). Bland-Altman analysis showed that there was a good agreement in AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700(P=0.0809). The AL measured by infiltrating B ultrasound guided segmented A-scan and IOL Master 700 was positively correlated(rs=0.992, P<0.0001), and the AL was positively correlated between preoperative contact A-scan and postoperative IOL Master 700(rs=0.989, P<0.0001).CONCLUSION:For dense cataract, infiltrating B ultrasound guided A-scan segment biometric measurement, which has good correlations and agreement, is closer to the AL measured by IOL Master 700 postoperatively than that measured by contact A-scan.
RESUMEN
This study aimed to explore the value of magnetic resonance imaging (MRI) T 2 mapping in the assessment of dermatomyositis (DM) and polymyositis (PM). Thirty-three confirmed cases (myosin group) and eight healthy volunteers (healthy control group) at the Department of Rheumatology and Immunology, the First Affiliated Hospital of Kunming Medical University, from October 2016 to December 2017, were collected and analyzed. Multiple parameters of the myosin group were quantified, including creatine kinase (CK), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), complement C3, and complement C4. Disease status was evaluated using a panel of tools: myositis disease activity assessment tool-muscle (MDAAT-muscle), myositis disease activity assessment tool-whole (MDAAT-all), health assessment questionnaire (HAQ), medical outcomes study health survey short form-36 item (SF-36), hand muscle strength test (MMT-8) score, and MRI T 2 mapping of muscle (22 muscles in the pelvis and thighs) T 2 values. The results showed that in the myositis group, the measurements for CK, ESR, CRP, complement C3, and complement C4 were 457.2 (165.6, 1 229.2) IU/L, 20 (10, 42) mm/1h, 3.25 (2.38, 10.07) mg/L, 0.90 (0.83, 1.06) g/L, and 0.18 (0.14, 0.23) g/L, respectively. The scores for MMT-8, MDAAT-muscle, MDAAT-all, HAQ, and SF-36 were 57.12±16.23, 5.34 (4.00, 6.00), 34.63±12.62, 1.55 (0.66, 2.59), and 44.66±7.98, respectively. T 2 values were significantly higher in all 22 muscles of the pelvis and thighs of patients with DM or PM compared with the healthy controls [(54.99±11.60)ms vs. (36.62±1.66)ms, P<0.001], with the most severe lesions in the satrorius, iliopsoas, piriformis, gluteus minimus, and gluteus medius muscles. The total muscle T 2 value in the myositis group was positively correlated with CK, MDAAT-muscle, MDAAT-all, and HAQ ( r=0.461, 0.506, 0.347, and 0.510, respectively, all P<0.05). There was a negative correlation between complement C4, SF-36, and MMT-8 scores ( r=-0.424, -0.549, and -0.686, respectively, all P<0.05). Collectively, the findings from this study suggest that MRI T 2 mapping can objectively reflect the disease status of DM and PM.

RESUMEN
ObjectiveBased on network pharmacology and transcriptomics, the mechanism of Zishen Qinggan prescription (ZSQGF) in improving glucose and lipid metabolism in type 2 diabetes (T2DM) model rats was explored. MethodBased on network pharmacology analysis of the differential genes between ZSQGF and T2DM, gene ontology(GO)analysis and Kyoto encyclopedia of genes and genomes(KEGG) analysis were conducted, and molecular docking analysis was used to verify the binding between components and targets. A T2DM rat model was established by high-fat feeding and injection of streptozotocin (STZ). The rats were randomly divided into the control group, model group, metformin (Met, 72 mg·kg-1) group, and ZSQGF high-, medium-, and low-dose groups (ZSQGF-H, ZSQGF-M, and ZSQGF-L, with 4.8, 2.4, and 1.2 g·kg-1 raw drug in the solution). The living status of rats was monitored and the levels of total cholesterol (TC), total triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in rat serum were detected. The liver tissues were subjected to Hematoxylin eosin(HE) staining and oil red O staining. The differential genes were analyzed through transcriptomics, GO and KEGG analysis, and the protein-protein interaction(PPI) network was obtained to screen key targets. With network pharmacology and transcriptomics analysis results, the protein pathways were identified. The expression levels of nuclear factor-κB (NF-κB), matrix metalloproteinase(MMP)-1 and MMP-9 proteins in liver tissues were detected by Western blot. The mRNA expression of B-cell lymphoma-2(Bcl-2) modifying factor(BMF), nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 4 (NOX4), and fatty acid synthase(FASN) was detected by real-time polymerase chain reaction(Real-time PCR). The expression of MMP-1 and MMP-9 in the liver was detected by immunofluorescence staining. ResultTranscriptomics and network pharmacology analysis suggested that ZSQGF may protect the liver through the glucose and lipid metabolism pathway and the inflammation pathway. Experiments showed that after 8 weeks of administration, the body weight, blood sugar, serum indicators, and pathological staining results of rats were improved. Western blot results indicated a decrease in the relative expression levels of NF-κB, MMP-1 and MMP-9 proteins in the liver. Real-time PCR results showed a decrease in the transcriptional expression of BMF, NOX4, and FASN in the ZSQGF-H group, while immunofluorescence staining results present decreased expression of MMP-1 and MMP-9 in the ZSQGF groups. ConclusionZSQGF can improve the glucose and lipid metabolism by inhibiting the expression of FASN, reducing lipid synthesis, and regulating the NF-κB signaling pathway.
RESUMEN
Objective To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy(ERAT)with laparoscopic appendectomy(LA)for acute uncomplicated appendicitis using propensity score matching.Methods The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected.The cases were classified based on the differences in surgical method and divided into the ERAT group(n = 30)and LA group(n = 411).The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching(PSM).Results After PSM,a total of 30 pairs of patients in the two groups were successfully matched,and the baseline data of the two groups met the requirements for comparability.At 24 hours after the operation,the ERAT group exhibited lower white blood cells,neutrophil counts,and C-reactive protein levels compared to the LA group,and these differences were statistically significant(P<0.05).There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group(P>0.05).However,the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group,and these differences were statistically significant(P<0.05).Conclusion Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective,safe,and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.

Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.
RESUMEN
The online and offline hybrid teaching model of evidence-based medicine (EBM) is currently in the stage of development. Previous teaching focused on the teaching process in the classroom, and did not organically combine all the course contents before, during, and after class. The BOPPPS model can be used to establish coherence and integrity in the EBM teaching process. Considering the discipline characteristics and teaching objectives of EBM, this study initially explored and designed a BOPPPS-based online and offline hybrid teaching model. Taking the "diagnostic evidence" module as an example, the teaching implementation details were introduced. A pre-designed questionnaire was used to conduct baseline survey and follow-up survey on students before and after class to evaluate the teaching model and effect. The surveys showed that half of the students (77/154) preferred the new online and offline hybrid teaching model of EBM. The students found that all aspects of BOPPPS teaching were generally acceptable and satisfactory. Compared with before teaching, the students' proficiency in EBM was significantly improved after the teaching ( P<0.001), particularly in their ability to retrieve literature and evaluate the quality of evidence, which is of great significance for expanding their knowledge and clinical thinking.

RESUMEN
Objective:To evaluate the active monitoring methods and population characteristics of trimetazidine-associated Parkinson's syndrome.Methods:The clinical data of patients with trimetazidine-associated Parkinson's syndrome who received treatment in Liaocheng People's Hospital from January 2019 to December 2020 were retrospectively analyzed using the China Hospital Pharmacovigilance System (CHPS).Results:In 4 883 patients included in the study,167 patients were alarmed by CHPS, of which 26 patients were confirmed positive by manual rechecks. The rate of positive pre-alarming by CHPS was 15.57%. The actual incidence of trimetazidine-associated Parkinson's syndrome was 0.53%. The average age of the 26 patients with Parkinson's syndrome was (75.08 ± 10.79) years. None of the 26 patients had a past history/family history of idiopathic Parkinson's disease. There were 21 patients (80.77%) aged over 65 years, 19 patients (73.08%) with a history of ischemic encephalopathy, 17 patients (65.38%) with positive symptoms in both limbs, 20 patients (76.92%) with abnormal brain CT or MRI findings, and 21 patients (80.77%) with medication doses of 60-70 mg/d. Among the 26 patients, 18 were female patients (69.23%) and 18 were patients with normal renal function (69.23%). The follow-up results showed that trimetazidine administration was not terminated in 14 patients (53.85%), symptoms were not alleviated or worsened in 8 patients (30.77%), and symptoms were alleviated or disappeared in 18 patients (69.23%).Conclusion:The use of CHPS can timely detect trimetazidine-associated Parkinson's syndrome. CHPS has significant advantages over traditional monitoring modes. Age > 65 years and a previous history of ischemic encephalopathy are risk factors for developing trimetazidine-associated Parkinson's syndrome. No history/family history of idiopathic Parkinson's disease, positive Alzheimer's disease symptoms in both limbs and abnormal brain CT and MRI findings contribute to early diagnosis and differentiation of trimetazidine- associated Parkinson's syndrome. Trimetazidine-associated Parkinson's syndrome is more common in women than in men. Trimetazidine-associated Parkinson's syndrome can also occur in a population with normal renal function or under a normal trimetazidine dose condition. Trimetazidine-associated Parkinson's syndrome is relatively rare. Patients with trimetazidine- associated Parkinson's syndrome have low awareness. Because of the difficult diagnosis and serious consequences, there is a need to strengthen research on trimetazidine-associated Parkinson's syndrome.
RESUMEN
Anaplastic thyroid cancer (ATC) is the most malignant thyroid cancer with a low incidence but high mortality. ATC is highly aggressive, rapidly progressing, and has poor prognosis. Current treatment options is not efficacious, so there is an urgent need to investigate its pathogenesis to update the treatment and improve the survival rate. Previous studies have found that most ATC can develop from well-differentiated thyroid cancer, and BRAF and RAS mutations are the key driving factors of ATC. TP53, PI3K pathway, PTEN, TERT, SWI/SNF complex Subunit, NF2 and other mutations also play an important role in the occurrence of ATC. Recent studies have found that single gene mutation is often not sufficient to drive the occurrence of ATC, and ATC is usually developed from the accumulation of multiple mutations in well-differentiated thyroid cancer. Therefore, this paper reviews the role of common combined mutations in ATC, deepens the understanding of the pathogenesis, and provides a basis for finding effective therapeutic targets.
RESUMEN
Objective:To investigate the effect of immune checkpoint inhibitors combined with concurrent chemotherapy for non-small cell lung cancer (NSCLC) and the effect of this regimen on serum levels of tumor marker and immune cells of patients.Methods:The clinical data of 60 NSCLC patients in Xuzhou Cancer Hospital from February 2020 to February 2022 were retrospectively analyzed, and they were divided into chemotherapy combined with immune checkpoint inhibitor treatment group (combination treatment group) and conventional chemotherapy group by treatment methods, with 30 cases in each group. Before treatment and 6 weeks after treatment, the patients' serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), vascular endothelial growth factor (VEGF), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) were detected by chemiluminescence immunoassay, and the levels of serum tumorous M2 pyruvate kinase (TuM2-PK) and fatty acid synthase (FAS) were detected by double-antibody sandwich enzyme-linked immunosorbent assay. The levels of T cell subsets were measured by flow cytometry, and the quality of life of patients was evaluated according to the World Health Organization quality of life scale brief version (WHOQOL-BREF). The clinical efficacy, tumor markers levels, immune cells levels, quality of life and adverse reactions were compared between the two groups.Results:The overall effective rate of patients in the combination treatment group was 46.67% (14/30), which was higher than 20.00% (6/30) in the conventional chemotherapy group ( χ2 = 4.80, P = 0.029). The differences in serum CEA, CA125, VEGF, CYFRA21-1, TuM2-PK, FAS levels and the proportions of CD3 +, CD4 +, CD8 + T cells and WHOQOL-BREF scores between the two groups before treatment were not statistically significant (all P > 0.05); the levels of CEA, CA125, VEGF, CYFRA21-1, TuM2-PK, FAS and the proportion of CD8 + T cells at 6 weeks after treatment were lower than those before treatment in both groups (all P < 0.05), and the proportions of CD3 + and CD4 + T cells and WHOQOL-BREF scores were higher than those before treatment (all P < 0.05); the levels CEA, CA125, VEGF, CYFRA21-1, TuM2-PK and the proportions of CD8 + T cells in the combination treatment group at 6 weeks after treatment were higher than those in the conventional chemotherapy group at 6 weeks after treatment (all P < 0.001), and the proportions of CD3 + and CD4 + T cells and WHOQOL-BREF scores were higher than those in the conventional chemotherapy group at 6 weeks after treatment (all P < 0.05). The differences in the incidence of gastrointestinal reactions, alopecia, leukopenia, thrombocytopenia, and liver and kidney function impairment between the two groups were not statistically significant (all P > 0.05). Conclusions:Immune checkpoint inhibitors combined with chemotherapy in NSCLC patients are more effective than conventional chemotherapy, and the combined treatment can more effectively reduce the serum tumor marker levels of patients and enhance the anti-tumor immune effect, with the adverse reactions comparable to conventional chemotherapy.
