RESUMO
OBJECTIVE To explore the role of clinical pharmacists in identifying paroxysmal spasms caused by drugs, and provide reference for rational drug use. METHODS Retrospective analysis was conducted on pharmaceutical care provided by clinical pharmacists for a patient with ceftazidime-avibactam (CZA-AVI) induced paroxysmal spasms. The clinical pharmacists identified, analyzed and summarized the clinical manifestations, risk factors and treatment methods of the nervous system toxicity caused by antibacterial drugs. According to the patient’s clinical symptoms and test results, the clinical pharmacists recommended temporarily discontinuing the use of polymyxin B and montelukast sodium, and halving the dose of CZA-AVI. The physicians did not adopt the recommendation to halve the dose of CZA-AVI, and when the patient’s neurologic toxicity did not improve, the clinical pharmacists again recommended discontinuing CZA-AVI, which was accepted by the physicians. RESULTS Clinical pharmacists analyzed the condition and checked related drugs that caused paroxysmal spasms of extremities one by one, and finally determined that CZA-AVI might be the drug that caused paroxysmal spasms of extremities in the patient. After stopping the drug, the patient’s symptoms improved and was transferred to a community hospital for rehabilitation treatment. CONCLUSIONS The dose of CZA-AVI should be adjusted according to the renal function and the neurotoxicity should be guarded against, especially for patients with advanced age, renal insufficiency, and the combined use of multiple drugs related to nephrotoxicity and neurotoxicity.

RESUMO
The twenty-first century has already recorded more than ten major epidemics or pandemics of viral disease, including the devastating COVID-19. Novel effective antivirals with broad-spectrum coverage are urgently needed. Herein, we reported a novel broad-spectrum antiviral compound PAC5. Oral administration of PAC5 eliminated HBV cccDNA and reduced the large antigen load in distinct mouse models of HBV infection. Strikingly, oral administration of PAC5 in a hamster model of SARS-CoV-2 omicron (BA.1) infection significantly decreases viral loads and attenuates lung inflammation. Mechanistically, PAC5 binds to a pocket near Asp49 in the RNA recognition motif of hnRNPA2B1. PAC5-bound hnRNPA2B1 is extensively activated and translocated to the cytoplasm where it initiates the TBK1-IRF3 pathway, leading to the production of type I IFNs with antiviral activity. Our results indicate that PAC5 is a novel small-molecule agonist of hnRNPA2B1, which may have a role in dealing with emerging infectious diseases now and in the future.

AIM: To compare the efficacy of and without small incision lenticule extraction(SMILE)with cyclotorsion compensation for astigmatism correction.METHODS: PubMed, Web of Science, EMBASE, Cochrane and CNKI, VIP, CBM, and Wan Fang Data were searched for clinically controlled studies from January 2010 to August 2022, including an experimental group with cyclotorsion compensation during SMILE and a control group without cyclotorsion compensation during SMILE. After literature screening, quality evaluation, and data extraction by two researchers independently, the Meta-analysis of uncorrected distance visual acuity(UDVA), residual astigmatism, vector analysis indicators for measuring the astigmatism correction including absolute value of angle of error(|AE|)and magnitude error(ME), and post-operative total higher order aberrations, spherical aberration and coma was carried out with Stata 16.0 software.RESULTS: Seven studies with a total of 846 eyes(442 in the experimental group, 404 in the control group)were finally included. The Meta-analysis showed that there were significant differences in the percentage of eyes with residual astigmatism ≥1.00D(OR=0.17, 95%CI: 0.06~0.49, P<0.01), |AE|(WMD=-1.56, 95%CI: -2.68~-0.45, P<0.01), the coma(WMD=0.06, 95%CI: -0.08~-0.04, P<0.01), and the total higher order aberrations(WMD=-0.04, 95%CI: -0.06~-0.02, P<0.01). However, there were no differences in the postoperative UDVA(WMD=0.00, 95%CI: -0.02~0.01, P=0.54), residual astigmatism(WMD=0.08, 95%CI: -0.02~0.18, P=0.10), ME(WMD=-0.01, 95%CI: -0.14~0.12, P=0.85), and the spherical aberration(WMD=0.03, 95%CI: -0.07~0.13, P=0.52).CONCLUSION: Cyclotorsion compensation in SMILE can reduce the angular error caused by eye rotation during astigmatism correction. It also decreases postoperative residual astigmatism. Overall, the SMILE with cyclotorsion compensation is superior in clinical efficacy of the precise correction of astigmatism.
RESUMO
AIM: To compare the changes in corneal densitometry after small incision lenticule extraction(SMILE)and femtosecond laser in situ keratomileusis(FS-LASIK)and investigate the effect of corneal interface haze on vision after SMILE.METHODS: Prospective cohort study. A total of 93 patients(186 eyes)who were scheduled to undergo refractive surgery at the Ophthalmic Refractive Surgery Center of the Affiliated Hospital of Nantong University from May 2020 to October 2021 were included in the study, and there were 48 patients(96 eyes)in the SMILE group and 45 patients(90 eyes)in the FS-LASIK group. The changes in corneal densitometry, spherical equivalent(SE), and uncorrected visual acuity(UCVA)were observed and compared between the two groups before and at 1d, 1wk, 1, 3 and 6mo after surgery.RESULTS: The 93 patients all successfully completed the surgery, and there were no related complications during and after the surgery, and there were no lost cases. The UCVA of FS-LASIK group was 0.044±0.064 and -0.001±0.065 respectively at 1d and 1wk after surgery, which was better than that of SMILE group(0.102±0.077 and 0.023±0.064; all P<0.05). There was no statistical difference in the SE between the two groups at the postoperative follow-ups(P>0.05). The corneal densitometry values at 0-2 and 2-6 mm from corneal vertex and total corneal densitometry at 1d postoperatively in the FS-LASIK group were 18.0(17.5, 18.6), 16.2(15.6, 16.7)and 16.7(16.1, 17.3), which were lower than those of SMILE group [18.6(18.1, 19.3), 16.8(16.4, 17.4), 17.2(16.6, 17.8)](all P<0.05); The corneal densitometry values at 0-2 and 2-6 mm from corneal vertex and total corneal densitometry at 1wk postoperatively in the FS-LASIK group were 17.2(16.7, 17.6), 15.5(15.0, 15.9)and 15.9(15.3, 16.7), which were lower than those of SMILE group [17.6(17.1, 18.3), 16.0(15.6, 16.5), 16.6(15.9, 17.1)](all P<0.05).CONCLUSIONS: The transient interface haze after SMILE is responsible for the early higher corneal densitometry than FS-LASIK. The presence of interface haze is probably a factor for the quality of vision.
RESUMO
italic>Artemisia argyi (A. argyi) is a Chinese herbal medicine in China. The main active components are volatile oils, flavonoids, and other compounds, which have various pharmacological activities. Methoxylated flavonoids are the main active ingredients in A. argyi. Flavonoid O-methyltransferase (FOMT) is a key enzyme in the O-methylation of flavonoids. In order to further understand the function and characteristics of FOMT proteins, this paper carried out the whole genome mining and identification of FOMT genes in A. argyi and performed phylogenetic, chromosomal localization, gene sequence characterization, subcellular localization prediction, protein structure, gene structure analysis, and expression pattern analysis. The results showed that a total of 83 FOMT genes were identified in the genome of A. argyi. The phylogenetic tree shows that FOMT genes are divided into two subgroups, CCoAOMT (caffeoyl CoA O-methyltransferase) subfamily (32 genes) and COMT (caffeic acid O-methyltransferase) subfamily (51 genes). Gene sequence analysis showed that the number of amino acids encoded by FOMT was 70-734 aa, the molecular weight was 25 296.55-34 241.3 Da, and the isoelectric point was 4.51-9.99. Compared with 32 members of the CCoAOMT subfamily, nearly 1/3 of the 51 members of the COMT subfamily were hydrophobic proteins and 2/3 were hydrophilic proteins. Subcellular localization prediction showed that more than 80% of CCoAOMT subfamily members were located in the cytoplasm, and 96% of COMT subfamily members were located in the chloroplast. COMT subfamily members have more motifs than CCoAOMT subfamily members. The N-terminal motifs of COMT subfamily proteins are relatively variable, while the C-terminal motifs are relatively conserved. Expression pattern analysis showed that CCoAOMT subfamily members were mainly expressed in roots, while COMT members were mainly expressed in leaves. Some FOMTs showed the tissue expression specificity by real-time quantitative PCR analysis, especially in leaves. In this study, we identified and analyzed the FOMT gene family in A. argyi, and provided a theoretical basis for further research on the function of FOMTs and the biosynthesis of methylated flavonoids in A. argyi.
RESUMO
Objective To explore the correlation between acute myocardial infarction(AMI)and neutrophil extracellular traps-os-is(NETosis)in the regulation of cardiomyocyte autophagy in mice.Methods The mouse model of AMI was established in C57BL/6mice by ligation of the left anterior descending coronary artery.Mouse primary cardiomyocytes were treated with oxygen glucose deprivation(OGD)to build an in vitro model of cardiomyocyte injury.Neutrophils were treated with PMA(NETosis inducer)/DNas Ⅰ(NETosis in-hibitor),the supernatant was taken to treat OGD-induced cardiomyocytes,and rapamycin(Rap)was used to treat OGD-induced car-diomyocytes.The myocardial infarction area was detected by TTC staining;serum cTnI level was detected by enzyme-linked immunoad-sordent assay(ELISA);cardiomyocytes apoptosis was detected by TUNEL staining;NETosis marker levels in neutrophil supernatant were detected by ELISA,and related protein expression levels were detected by Western blot.Results TTC staining showed that compared with the sham-operated group,the myocardial infarction area of the mice in the model group was significantly increased,the level of cTnI in serum was significantly increased(P<0.05),the apoptosis of cardiomyocytes was increased,and the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ were significantly increased,the p62 protein expression level was significantly decreased.Compared with the control group,the expression levels of apoptosis and cleaved caspase-3 were significantly increased under OGD conditions(P<0.05).Compared with the control group,the levels of NETosis markers MPO-DNA,MPO,and NE in the neutrophil supernatant in the PMA group were signifi-cantly increased;compared with the PMA-treated group the apoptosis level of cardiomyocytes in the PMA + DNas Ⅰ group was signifi-cantly decreased;the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰwere significantly decreased,and the protein expression level of p62 was significantly increased;compared with the PMA + DNas Ⅰ group,Rap treatment could enhance the levels of Beclin-1 and LC3-Ⅱ/LC3-Ⅰ,and inhibit the level of p62(P<0.05).It also significantly reversed the decrease in apoptosis induced by PMA + DNas Ⅰ.Conclusion Neutrophil NETosis can promote AMI in mice by regulating cardiomyocyte autophagy,which can provide a new direction and theoretical basis for the research and development of therapeutic drugs for AMI.
RESUMO
This study aims to investigate the expression, prognosis, and clinical significance of C5orf46 in gastric cancer and to study the interaction between the active components of C5orf46 and tarditional Chinese medicine. The ggplot2 package was utilized for differential expression analysis of C5orf46 in gastric cancer tissues and normal tissues. The survival package was used for survival analysis, univariate regression analysis, and multivariate regression analysis. Nomogram analysis was used to assess the connection between C5orf46 expression in gastric cancer and overall survival. The abundance of tumor-infiltrating lymphocytes was calculated by GSVA package. Coremine database, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database, and PubChem database were used to search the potential components corresponding to C5orf46 gene and tarditional Chinese medicine. Molecular docking was performed to explore the binding affinity of potential components to C5orf46. Cell experiments were performed to explore the expression of C5orf46 gene in cells of the blank group, model group, and drug administration groups. As compared with normal tissues, C5orf46 expression was higher in gastric cancer tissues, which had more significant predictive effects in the early stages(T2, N0, and M0). The more advanced the tumor node metastasis(TNM) stage, the higher the C5orf46 expression and the lower the probability of survival of patients with gastric cancer. The expression of C5orf46 positively correlated with the helper T cells1 in gastric cancer and the macrophage infiltration level in gastric cancer, and negatively correlated with B cells, central memory T cells, helper T cells 17, and follicular helper T cells. Seven potential components of C5orf46 were obtained, and three active components were obtained after the screening, which matched five tarditional Chinese medicines, namely, Sojae Semen Nigrum, Jujubae Fructus, Trichosanthis Fructus, Silybi Fructus, and Bambusae Concretio Silicea. Molecular docking revealed that sialic acid and adeno-sine monophosphate(AMP) had a good binding ability to C5orf46. The results of real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot showed that, as compared with the model group, the mRNA and protein expression levels of C5orf46 were significantly lower in the drug administration groups. The lowest expression level was found at the concentration of 40 μmol·L~(-1). The results of this study provide ideas for the clinical development of traditional Chinese medicine compounds for the treatment of gastric cancer as well as other cancers.

Management and treatment of terminal metastatic castration-resistant prostate cancer (mCRPC) remains heavily debated. We sought to investigate the efficacy of programmed cell death 1 (PD-1) inhibitor plus anlotinib as a potential solution for terminal mCRPC and further evaluate the association of genomic characteristics with efficacy outcomes. We conducted a retrospective real-world study of 25 mCRPC patients who received PD-1 inhibitor plus anlotinib after the progression to standard treatments. The clinical information was extracted from the electronic medical records and 22 patients had targeted circulating tumor DNA (ctDNA) next-generation sequencing. Statistical analysis showed that 6 (24.0%) patients experienced prostate-specific antigen (PSA) response and 11 (44.0%) patients experienced PSA reduction. The relationship between ctDNA findings and outcomes was also analyzed. DNA-damage repair (DDR) pathways and homologous recombination repair (HRR) pathway defects indicated a comparatively longer PSA-progression-free survival (PSA-PFS; 2.5 months vs 1.2 months, P = 0.027; 3.3 months vs 1.2 months, P = 0.017; respectively). This study introduces the PD-1 inhibitor plus anlotinib as a late-line therapeutic strategy for terminal mCRPC. PD-1 inhibitor plus anlotinib may be a new treatment choice for terminal mCRPC patients with DDR or HRR pathway defects and requires further investigation.

Objective:To investigate the synergistic antitumor effect of pyrotinib in combination with 5-fluorouracil(5-Fu)on human epidermal growth factor receptor 2(HER2)positive breast cancer cells and its underlying molecular mechanism. Methods:HER2 positive breast cancer cells were screened by Western blotting.HER2 positive SKBR-3 and BT474 cells were treated with pyrotinib and 5-Fu individually or in combination for the following experiments.MTT assay was used to assess the effect of different drugs on the proliferation of the treated cells,and the combination index(CI)values were calculated using Combidrug software.Colony formation assay was used to evaluate the effect of different drugs on the colony-forming ability of the treated cells.FCM assay was used to analyze the effect of different drugs on the apoptosis rate and cell cycle of the treated cells.Western blotting was used to examine the effect of different drugs on the expression levels of proteins in the proliferation-and apoptosis-related signaling pathways.SKBR-3-cell-based tumor xenograft model was established using BALB/c nude mice.After treatment with pyrotinib and 5-Fu individually or in combination,the growth profiles of the xenograft tumors were recorded and the expression levels of proteins in the proliferation-and apoptosis-related signaling pathways were examined in the tumor tissues. Results:HER2 positive breast cancer cell lines SKBR-3 and BT474 were selected for further experiments after screening.The proliferation SKBR-3 and BT474 cells could be inhibited after treatment with pyrotinib and 5-Fu individually or in combination(all P<0.05).Compared with pyrotinib or 5-Fu single drug treatment,pyrotinib in combination with 5-Fu had higher inhibition rate on the proliferation of SKBR-3 and BT474 cells with a Cl value of<1,indicating the synergistic effect of pyrotinib and 5-Fu.In addition,in contrast to pyrotinib or 5-Fu single drug treatment,there was a further decrease in the number of colonies formed,increase in apoptosis rate,and increase in the percentage of G0/G,cells in SKBR-3 and BT474 cells after treatment with pyrotinib in combination with 5-Fu(all P<0.01).Animal experiment results showed that the growth rate of xenograft tumors in mice treated with pyrotinib in combination with 5-Fu was significantly slower than that of the single-drug treated mice(P<0.05).Western blotting analysis showed that the expression levels of HER2,HER4,AKT and phosphorylated ERK were significantly decreased after treatment with pyrotinib in combination with 5-Fu both in vitro and in vivo(all P<0.01),indicative of the blockage of proliferation-related signaling pathways.Meanwhile,analysis of the apoptosis-related proteins revealed a decrease in the expression levels of caspase 3,poly ADP-ribose polymerase(PARP),and Bcl-2(all P<0.01),while an increase in the expression levels of cleaved-caspase 3,cleaved-PARP,and p21(all P<0.01). Conclusion:Pyrotinib and 5-Fu had synergistical antitumor effect on HER2 positive breast cancer cells,and the underlying mechanism may be related to the blockage of proliferation-associated signaling pathways and the induction of apoptosis and cell cycle arrest.
RESUMO
Objective:To assess the prevalence of metabolic syndrome(MS) and its relationship with hyperuricemia(HUA) in perimenopausal women in Anning city, Yunnan province.Methods:This is a cross-sectional survey. In May 2021, a multi-stage stratified sampling method was used to collect demographics and clinical data [ethnicity, living community, height, weight, waist circumference, blood pressure, fasting plasma glucose, triglycerides(TG), serum uric acid, high density lipoprotein-cholesterol(HDL-C), alanine transaminase(ALT), etc] in a total of 6 721 perimenopausal women aged 45-60 years.Results:A total of 6 721 perimenopausal women were included in this study. The prevalences of MS and HUA were 14.05%(95% CI 13.22%-14.88%) and 6.46%(95% CI 5.88%-7.07%), respectively. The average age, HDL-C, urea, direct bilirubin, and albumin levels in the perimenstrual HUA population were lower than those in the non-HUA population while the levels of TG, ALT, heart rate, body mass index(BMI), and creatinine were higher(all P<0.05). The prevalence of HUA in perimenopausal women with ethnic minorities and family history of chronic diseases was higher than that in Han nationality and without family history of chronic diseases. The prevalence of MS in perimenopausal women was increased with the increase of serum uric acid( Z=-15.313 8, P<0.001). Multivariate logistic regression model showed that HUA was positively correlated with MS( OR=1.526, 95% CI 1.192-1.954) after adjusting for covariates such as BMI and ethnicity, and the incidence of MS in perimenopausal women in HUA group was 1.526 folds higher than that in non-hyperuricemia group. Conclusion:HUA is highly positively correlated with MS in perimenopausal women. The management of uric acid level in perimenopausal women should be strengthened.
RESUMO
BackgroundThe treatment of patients with depressive disorders is short of targeted outcome assessment. As a secondary outcome that is guided by patient values, quality of life is thus of relatively high evaluative value. In China, there exists a lack of large sample prospective cohort studies evaluating the effect of different treatment protocols on quality of life in patients with acute depressive disorder. ObjectiveTo explore the effects of monotherapy and combination therapy on the quality of life of patients with depressive disorder in acute phase, so as to provide references for optimizing the outcome of treatment for such patients. MethodsA prospective follow-up cohort study from August 24, 2020 to November 29, 2021 was conducted, including 1 330 patients from 22 hospitals across 18 cities in China. All these patients met the diagnostic criteria for depressive episodes, recurrent depressive disorder from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). Patients were divided into monotherapy group (n=969) and combination therapy group (n=361) according to the acute phase treatment protocol. At baseline, the end of the first half month as well as the 1st, 2nd, 3rd, 6th, 9th and 12th months of treatment, patients were assessed with Inventory of Depressive Symptomatology Self-report (IDS-SR30), Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF), Concise Health Risk Tracking Scale (CHRT) and Siehan Disability Scale (SDS). Frequency, Intensity, and Burden of Side Effects Rating (FIBSER) was adopted for assessment at each visit time point of treatment. Spearman correlation analysis was adopted to examine the correlation of quality of life with suicide risk, adverse reactions and impaired social functioning among patients. ResultsAt the end of three months of treatment, the Q-LES-Q-SF score of monotherapy group was higher than that of combination therapy group, and the difference was statistically significant (Z=2.008, P<0.05). The time effects of both treatment protocols possessed statistical significance (F=111.393, P<0.01). At the end of three months of treatment, the Q-LES-Q-SF score was negatively correlated with CHRT and SDS scores, respectively, in both monotherapy group and combination treatment group (r=-0.660, -0.712, -0.634, -0.718, P<0.01). ConclusionBoth monotherapy and combination therapy can facilitate the improvement of the life quality of patients with acute depressive disorder, but monotherapy may achieve better than the combination therapy in this aspect.

Aim To investigate the effect of curcumin extract on melanin production and melanosome transport, and to explore the possible mechanism of the curcumin extract on microenvironment. Methods (1) B16F10 and HaCaT cells were cultured with different concentrations of curcumin. The proliferation ability was detected by MTT method. Melanin synthesis and tyrosinase activity in B16F10 cells were detected by NaOH pyrolysis method and Oxidation dopamine response in vitro. The expression levels of key proteins were detected by Western blot. (2) B16F10 cells were cultured with different concentrations of ISG15 protein. NaOH pyrolysis method and Oxidation dopamine response in vitro were used to detect melanin synthesis and tyrosinase activity in B16F10 cells. Results Curcumin could directly inhibited tyrosinase activity and melanin production, and inhibit melanocyte migration within a certain concentration range. ISG15 protein could enhance the melanin production, tyrosinase activity. Curcumin could reduce the expression of the ISG15 in HaCaT cell, change the microenvironment of melanocyte, and indirectly inhibit melanin synthesis through ISG15. Conclusions In addition to directly inhibiting melanin synthesis, curcumin can also play an indirect role in inhibiting melanin synthesis by inhibiting the expression of ISG15 protein and altering the microenvironment of melanocytes.
RESUMO
italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.
RESUMO
Objective@#To analyze the prevalence of dry and wet age-related macular degeneration (AMD) in patients with diabetes, hypertension and hyperlipidemia, and to analyze the risk factors for AMD.@*Methods@#A population-based cross-sectional epidemiologic study was conducted involving 14,440 individuals. We assessed the prevalence of dry and wet AMD in diabetic and non-diabetic subjects and analyzed the risk factors for AMD.@*Results@#The prevalence of wet AMD in diabetic and non-diabetic patients was 0.3% and 0.5%, respectively, and the prevalence of dry AMD was 17% and 16.4%, respectively. The prevalence of wet AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 0.5%, 0.3%, 0.2%, and 0.7%, respectively. The prevalence of dry AMD in healthy, hypertensive, hyperlipidemic, and hypertensive/hyperlipidemic populations was 16.6%, 16.2%, 15.2%, and 17.2%, respectively. Age, sex, body mass index, and use of hypoglycemic drugs or lowering blood pressure drugs were corrected in the risk factor analysis of AMD. Diabetes, diabetes/hypertension, diabetes/hyperlipidemia, and diabetes/hypertension/hyperlipidemia were analyzed. None of the factors analyzed in the current study increased the risk for the onset of AMD.@*Conclusion@#There was no significant difference in the prevalence of wet and dry AMD among diabetic and non-diabetic subjects. Similarly, there was no significant difference in the prevalence of wet and dry AMD among subjects with hypertension and hyperlipidemia. Diabetes co-existing with hypertension and hyperlipidemia were not shown to be risk factors for the onset of dry AMD.

Objective:To explore the risk factors of antiplatelet drug compliance after stent implantation in patients with lower extremity arteriosclerosis obliterans, and to construct an online prediction model tool.Methods:Retrospective analysis of the clinical data of patients with lower extremity arteriosclerosis obliterans who received lower extremity arterial stent implantation in Department of Vascular Surgery, Provincial Hospital Affiliated to Shangdong First Medical University from January 2019 to January 2021 was carried out. 90 patients with poor compliance and 90 patients with good compliance were selected into the observation group and the control group, respectively. Univariate analysis was used to screen the influencing factors of antiplatelet drug compliance, and the variables with statistical significance were substituted into the binary Logistic regression to carry out independent risk factor test to screen the risk factors of cross-over antiplatelet drug compliance and establish the prediction model.Results:Married ( OR = 0.316, 95% CI 0.135-0.738), number of follow-up visits during the follow-up period ( OR = 0.866, 95% CI 0.760-0.987), the amount of medication ( OR = 0.755, 95% CI 0.654-0.919) were the protective factors for the compliance of antiplatelet drugs in patients with lower extremity arteriosclerosis obliterans after stent implantation. Advanced age ( OR = 1.136, 95% CI 1.066-1.211), male ( OR = 3.727, 95% CI 1.533-9.060), junior high school and below education level ( OR = 4.949, 95% CI 1.501-16.313), the average monthly income less than 3 000 yuan ( OR = 15.774, 95% CI 4.487-55.495) and the monthly expenditure on medicine more than 500 yuan ( OR = 15.323, 95% CI 3.527-66.569) were the risk factors for the compliance of antiplatelet drugs in patients with lower extremity arteriosclerosis obliterans after stent implantation. The consistency index of this prediction model was 0.895, the area under the ROC curve was 0.875. Conclusion:The antiplatelet medication adherence prediction model established has high accuracy and good clinical application values.
RESUMO
Objective: To observe the effect of electroacupuncture (EA) at different time points during the perioperative period on the recovery of gastrointestinal function after gastrointestinal malignant neoplasms surgery. Methods: Sixty-three patients who needed radical surgery for gastrointestinal tumors were randomized into a control group, treatment group 1 (postoperative EA group), and treatment group 2 (intraoperative and postoperative EA group). The control group received surgery and conventional Western medicine treatment, and treatment groups 1 and 2 received additional EA treatment at different time points. The initial flatus time after the surgery, visual analog scale (VAS) score at different time points after the surgery, the proportion of using patient-controlled analgesia (PCA) after the surgery, and the times of adding analgesics were observed in the three groups. Results: The initial flatus time after the surgery was earlier in treatment groups 1 and 2 than in the control group (P<0.05); the difference between treatment groups 1 and 2 was statistically insignificant (P>0.05). The VAS score was lower in treatment group 2 than in the control group at 6, 12, 24, and 72 h after the surgery (P<0.05); the VAS score was lower in treatment group 1 than in the control group only at 72 h after the surgery (P<0.05). There were no significant differences in the rate of using PCA among the three groups (P>0.05). Regarding the times of adding analgesics, it was less in treatment group 2 than in the control group at 12 h after the surgery (P<0.05). Conclusion: Either EA during and after the surgery or only after the surgery can hasten the initial flatus and boost the recovery of gastrointestinal function in patients after radical resection of gastrointestinal neoplasms. Successive EA during and after the surgery should be superior to postoperative EA regarding the analgesic effect after the surgery.
