RESUMEN
Objective@#To explore incidence trend of hepatitis C in Chifeng City, Inner Mongolia Autonomous Region from 2008 to 2022, so as to provide the basis for formulating prevention and control measures for hepatitis C.@*Methods@#Data of reported hepatitis C cases in Chifeng City from 2008 to 2022 was collected through the Infectious Disease Information Reporting Management System. Trends in incidence of hepatitis C were analyzed using annual percent change (APC) and average annual percent change (AAPC). Impact of age, period and birth cohort on the risk of developing hepatitis C were analyzed by an age-period-cohort model.@*Results@#The annual average reported incidence rate of hepatitis C in Chifeng City was 59.13/105 from 2008 to 2022. The incidence showed an upward trend from 2008 to 2018 (APC=9.405%, P<0.05) and a downward trend from 2018 to 2022 (APC=-17.475%, P<0.05), but the overall trend was not statistically significant (AAPC=0.937%, P>0.05). The age-period-cohort model analysis showed that the incidence risks of hepatitis C in the residents aged 0 to 4 years and 45 to 84 years were higher than those in the residents aged 40 to 44 years (the control group). The incidence risk of hepatitis C increased with age from 40 to 79 years. Compared with 2008-2012, the incidence risk of hepatitis C showed an increasing trend followed by a decline in 2008-2022. The incidence risk was higher in 2013-2017 and lower in 2018-2022 than in 2008-2012. The incidence risk of hepatitis C showed an increasing trend followed by a decreasing trend by using the birth cohort from 1968 to 1972 as the control. The birth cohort from 1953 to 1977 had a higher incidence risk of hepatitis C than other birth cohorts.@*Conclusions@#The overall incidence of hepatitis C in Chifeng City from 2008 to 2022 appeared a tendency towards a decline, and the incidence risk increased with age. Screening and health education for the elderly and high-risk birth cohorts should be strengthened.
RESUMEN
@#Objective To compare the safety and comfort of patients with or without postoperative gastric tube placement after esophageal cancer surgery, and analyze the cost and nursing time of gastric tube placement. Methods The patients with esophageal cancer undergoing minimally invasive surgery in West China Hospital of Sichuan University in 2021 were enrolled. The patients were divided into a gastric tube indwelling group and a non gastric tube indwelling group according to whether the gastric tube was indwelled after the operation. The safety and comfort indicators of the two groups were compared. Results A total of 130 patients were enrolled. There were 66 patients in the gastric tube indwelling group, including 53 males and 13 females, aged 61.80±9.05 years and 64 patients in the non gastric tube indwelling group, including 55 males and 9 females, aged 64.47±8.00 years. Six patients in the non gastric tube indwelling group needed to place gastric tube 1 to 3 days after the operation due to their condition. There was no statistical difference in the incidence of postoperative complications between the two groups (P>0.05). The subjective comfort of patients in the gastric tube indwelling group was significantly lower than that in the non gastric tube indwelling group (P<0.001), and the incidence of foreign body sensation in the throat of patients in the gastric tube indwelling group was higher than that in the non gastric tube indwelling group (P<0.001). The average nursing time in the gastric tube indwelling group was about 59.58 minutes, and the average cost of gastric tube materials and nursing was 378.24 yuan per patient. Conclusion No gastric tube used after operation for appropriate esophageal cancer patients will not increase the incidence of postoperative complications (pulmonary infection, anastomotic leakage, chylothorax), but can increase the comfort of patients, save cost and reduce nursing workload, which is safe, feasible and economical.
RESUMEN
Abstract Background In a recent genome-wide association study, novel genetic variations of WNT9A were reported to be involved in the etiopathogenesis of thumb osteoarthritis (TOA) in Caucasians. Our purposes were to replicate the association of WNT9A with the development of TOA in the Chinese population and to further unveil the functional role of the risk variants. Methods SNP rs11588850 of WNT9A were genotyped in 953 TOA patients and 1124 healthy controls. The differences of genotype and allele distributions between the patients and healthy controls were evaluated using the Chi-square test. Luciferase Reporter Assay was performed to investigate the influence of variant on the gene expression. Results There was significantly lower frequency of genotype AA in TOA patients than in the controls 74.9% vs. 81.9%, p < 0.001). The frequency of allele A was remarkably lower in the patients than in the controls (86.3% vs. 90.5%, p < 0.001), with an odds ratio of 0.66 (95% CI = 0.54-0.80). Luciferase Reporter Assay showed that the construct containing mutant allele G of rs11588850 displayed 29.1% higher enhancer activity than the wild allele A construct (p < 0.05). Conclusions Allele G of rs11588850 was associated with the increased risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA. Key Points Genetic variants of WNT9A were associated with the incidence and severity of TOA. Allele G of rs11588850 was associated with an increased transcriptional activity of WNT9A promoter. Allele G of rs11588850 may add to the risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA.
RESUMEN
Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.
RESUMEN
Objective:To investigate the relationship between arterial blood partial pressure of carbon dioxide and neurological outcome after cardiopulmonary resuscitation.Methods:The clinical data of 116 patients who underwent cardiopulmonary resuscitation admitted to the Intensive Care Unit and Emergency Department of the Second People's Hospital of Hefei from January 2018 to January 2020 were retrospectively analyzed. According to the average arterial blood partial pressure of carbon dioxide within 24 hours after admission, patients were divided into normal (35 mmHg ≤ PaCO 2 ≤ 55 mmHg, 1 mmHg = 0.133 kPa, n = 44), hypercapnia (PaCO 2 > 55 mmHg, n = 51), and hypocapnia (PaCO 2 < 35 mmHg, n = 21) groups. ICU stay, in-hospital mortality, and neurological outcome at discharge were compared among groups. A logistic regression analysis model was established. The relationship between PaCO 2 and neurological outcome was determined. Results:There were no significant differences in age, sex, cardiac arrest time, acute physiological and chronic health evaluation II score at admission, 1-hour mean arterial pressure, location of cardiac arrest, and initial heart rhythm among the three groups (all P > 0.05). ICU stay in the normal group [(7.23 ± 2.55) days] was significantly higher than that in the hypercapnia [(12.21 ± 4.12) days] and hypocapnia [(11.78 ± 4.72) days] groups ( t = 6.48, 4.59, both P < 0.01). In-hospital mortality in the normal group was 38.6% (17/44), which was significantly lower than 60.8% (31/51) in the hypercapnia group and 66.7% (14/21) in the hypocapnia group ( χ2 = 4.63, 4.47, both P < 0.05). The good neurological outcome rate in the normal group was 55.6% (15/44), which was significantly higher than 25.0% (5/51) in the hypercapnia group and 28.6% (2/21) in the hypocapnia group ( χ2 = 8.38, 5.14, both P < 0.05). Multivariate logistic regression analysis showed that cardiac arrest time, 1-hour mean arterial pressure, acute physiological and chronic health evaluation II score, and PaCO 2 are important factors for neurological outcomes of resuscitated patients at discharge (all P < 0.01). Conclusion:Within 24 hours after cardiopulmonary resuscitation, maintaining a normal PaCO 2 level can help improve the neurological outcome of patients at discharge.
RESUMEN
Objective:To establish a prediction model of acute gastrointestinal injury (AGI) above grade II in elderly patients with severe pneumonia, and to evaluate and validate the model internally.Methods:A retrospective analysis was performed on 268 patients aged >65 years with severe pneumonia admitted to the Second People′s Hospital of Hefei from June 2019 to May 2022 (207 cases in the training set and 61 cases in the verification set). Sixteen indicators, including age, sex, underlying disease, pneumonia Severity index (PSI) score, dosage of sedative and analgesic drugs, and mechanical ventilation time of all patients were collected. After logistic regression analysis in the training set, a model was established to predict AGI above grade Ⅱ in elderly patients with severe pneumonia. Receiver operating characteristic (ROC) curve was drawed and correction curve was used to evaluate the reliability of the model. The model was internally validated by validation set data.Results:Among 207 patients with severe pneumonia in the training set, 50 patients developed AGI above grade Ⅱ during treatment. The prediction model was established by logistic regression analysis as follows: When L=Sequential Organ Failure Assessment (SOFA)×0.181+ PSI score×0.066+ propofol dosage×0.607+ reifentanil dosage×1.187, L>19.288, it can be considered that patients with severe pneumonia have a 93.24% chance of developing grade Ⅱ or above AGI. The ROC curve showed that the model was well differentiated, AUC=0.960. H-L test indicated (χ 2=7.39, P=0.496>0.05) the model fit was good. The sensitivity and specificity of the model were 82.00% and 96.82% respectively. AUC=94.58% (sensitivity 81.25%, specificity 93.33%), H-L test indicated ( χ 2=4.51, P=0.808>0.05) the prediction accuracy was 90.16%. Conclusions:The prediction model for AGI after severe pneumonia in elderly patients can be used clinically to help predict the occurrence of AGI in elderly patients with multiple injuries.

@#Abstract: Objective To understand the morphological characteristics and ultrastructure of the dominant species of Rhipicephalus sanguineus in Hainan at different developmental stages, and provide theoretical basis for the identification of the lineage and control of Rhipicephalus sanguineus. Methods The external morphology of different developmental stages of the dominant species of Rhipicephalus sanguineus, including larva, nymph and adult tick in Hainan were observed by scanning electron microscope. Results The division between each segment of larva pedipalps was not obvious, and setae was serrated; dental formula type 2 | 2; 3 pairs of podomere; a pair of setae on the anal valve; none of anal groove, spiracular plate, porous area and genital aperture. There was a clear boundary at the beginning of each segment of nymph pedipalps; dental formula type 2 | 2; 4 pairs of podomere; 3 pairs of setae on the anal valve; anal groove; none of porous area and genital aperture. The male adult tick's trichotheca are covered by the pedipalps, and the whole bristles are conical; dental formula type 3 | 3; 4 pairs of podomere; anal groove and paraprocts; 7 setae on the anal valve; genital aperture was oval. The female of adult tick can be distinguished by dental formula 3 | 3; pairs of podomere; porous areas with 3 short setae; anal groove; 4 pairs of setae and 2 pores on the anal valve; genital pore was broadly U-shaped. In addition, the male adult's scutum occupies almost the entire dorsal surface, the basis capituli of larva, nymph and adult tick all were hexagonal, and the existence of Haller's organ was found on the first pair of legs. Conclusions Scanning electron microscopy observation of the different developmental stages of R.sanguineus revealed clear morphological features, preliminarily suggesting that R.sanguineus in Hainan Province may belong to the tropical lineage, which provide a certain experimental basis for the identification of the tick and the comprehensive prevention and control of local tick-borne diseases.

RESUMEN
With the acceleration of aging society, delaying aging or promoting healthy aging has become a major demand for human health. 5-Lipoxygenase (5-LOX) is a key enzyme catalyzing arachidonic acid into leukotrienes (LTs), which is a potent mediator of the inflammatory response. Previous studies showed that abnormal activation of 5-LOX and overproduction of LTs are closely related to the occurrence and development of aging-related inflammatory diseases. Therefore, inhibiting 5-LOX activation is a possibly potential strategy for treating age-related diseases. In this paper, the latest research progress in 5-LOX activation, 5-LOX in mediating aging-related diseases and its small molecule inhibitors is briefly reviewed to provide scientific theoretical basis and new ideas for the prevention and treatment of aging-related inflammatory diseases.

Based on network pharmacology, molecular docking, and in vitro experimental verification, this study aims to explore the effect of Albiziae Cortex-Tribuli Fructus combination on HSC-LX2 pyroptosis. Specifically, the targets of Albiziae Cortex, Tribuli Fructus, and hepatic fibrosis were retrieved from an online database and CNKI, and "drug-component-target" network and "drug-component-target-disease" network were constructed. Protein-protein interaction(PPI) network was established based on STRING. Metascape was employed for Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment, and the mechanism of Albiziae Cortex-Tribuli Fructus combination against liver fibrosis was predicted. Molecular docking was used to verify some of the results of network pharmacology, and in vitro experiment was carried out to further verify the above conclusions. According to the results of network pharmacological analysis, 25 active components and 439 targets of Albiziae Cortex-Tribuli Fructus combination and 152 anti-liver fibrosis targets were screened out, including nucleotide-binding oligomerization domain and leucine-rich-repeat-and pyrin-domain-containing 3(NLRP3) and caspase-1. The key targets were involved in 194 KEGG pathways in which the NOD-like receptor signaling pathway topped. The binding common targets were related to pyroptosis. The results of in vitro experiment showed that the pair-containing serum reduced the proliferation rate of HSC-LX2 and the content of reactive oxygen species(ROS), interleukin-18(IL-18), and interleukin-1β(IL-1β)(P<0.05). Western blot and qRT-PCR suggested that the protein and gene expression of NLRP3, caspase-1, α-smooth muscle actin(α-SMA), and gasdermin D(GSDMD) in HSC-LX2 increased after AngⅡ stimulation, and the expression decreased after the intervention of pair-containing serum(P<0.05). In summary, the pair-containing serum can inhibit the classic pathway of pyroptosis, which may be the anti-liver fibrosis mechanism. This is consistent with the predicted results of network pharmacology.

@#Objective To analyze the changes of perioperative symptoms of lung cancer patients by using patient-reported outcomes at different time points. Methods A total of 109 patients who underwent thoracoscopic lung cancer resection in the department of thoracic surgery of our hospital from March to April 2021 were selected, including 55 (50.46%) males and 54 (49.54%) females. The mean age was 55.19±12.12 years. The postoperative symptom scale for lung cancer patients was used to investigate the changes of symptoms before surgery, 1 day after surgery, the day of discharge, and 30 days after surgery. Results The mean hospital stay was 6.89±2.25 days. None of the patients reported any clinical symptoms related to lung cancer before surgery. The most prominent symptoms 1 day after surgery were pain (3.33±0.96 points), nausea (2.81±1.18 points), dizziness (2.00±0.85 points), fatigue (1.89±0.79 points) and shortness of breath (1.79±1.37 points). The patients with dizziness, nausea, fatigue and other symptoms gradually decreased, and the symptoms were relieved significantly (P<0.05). However, the symptoms of conscious pain, cough and shortness of breath lasted for a long time. At 30 days after surgery, 70.64%, 64.22% and 33.03% of patients felt pain, cough and shortness of breath, respectively, and the degree of cough was aggravated (P<0.001). Conclusion Pain, cough, dizziness, shortness of breath and fatigue are the core postoperative symptoms of lung cancer patients. Most postoperative adverse symptoms can be effectively controlled in a short period of time, but pain, cough and shortness of breath still present persistent characteristics, which deserve further study.

@#Abstract: Objective In order to explore the application prospects of the phenyl pyrazole insecticide fipronil for mosquito control and identify potential target genes involved in the resistance of Aedes aegypti to fipronil, and lay the foundation for an in-depth study of the resistance mechanism of Aedes aegypti to fipronil. Methods Using Aedes aegypti sensitive strains as experimental materials, Aedes aegypti larvae were treated with fipronil, and the differences in gene expression of Aedes aegypti larvae before and after drug administration were compared at the transcriptome level using transcriptome sequencing combined with bioinformatics analysis, and the differential genes were analyzed. Results A total of 757 differentially expressed genes were identified between the fipronil-treated group and control group, including 217 and 540 up- and down-regulated genes, respectively. Among these, the expression of glutamate-gated chloride channel (GluCls) genes varied significantly before and after treatment. Gene ontology analysis revealed that differentially expressed genes were enriched in catalytic activity, binding, metabolic processes, and membrane-related functions, while KEGG pathway analysis indicated enrichment in biosynthesis, metabolism, and life regulation processes, while the glutathione metabolic pathway was enriched in 15 differentially expressed genes. Conclusions The transcriptome results revealed that GST gene expression was significantly upregulated in fipronil-treated Aedes aegypti larvae, indicating that GST gene is involved in the development of fipronil resistance in Aedes aegypti larvae. In addition, GluCls gene expression was also significantly different before and after treatment, suggesting that GluCls migh be a potential target receptor for fipronil resistance in Aedes aegypti. As GluCls is an ideal target receptor found only in invertebrates, this discovery provides a reference and basis for further exploration of the toxicological mechanism of fipronil on Aedes aegypti.
RESUMEN
Objective@#To explore the effect of the comprehensive intervention on overweight and obesity among middle school students at the population level (health education lecture and official account push) and individual level (personalized dietary guidance), so as to provide a reference for preventing and controlling their overweight and obesity.@*Methods@#Three junior high schools and three senior high schools were randomly selected in Guangzhou in 2018 by convenience sampling. Through physical examination, 1 457 overweight and obese students aged from 12 to 18 years old were screened. Intervention was administered through "Student Personalized Dietary Guidance" manual, health tweets on the official accounts, and health education lectures from September 2018 to December 2019. The Chi square test was used to compare the difference in overweight and obesity constituent ratio between the two groups before and after the intervention. And intervention effect was evaluated by analyzing the number needed to treated(NTT).@*Results@#The proportion of overweight before the intervention was 66.71% (972/1 457), and decreased to 59.92% (873/1 457) after the intervention; the proportion of obesity before the intervention was 33.29% (485/1 457), which decreased to 26.63% (388/1 457) after the intervention. Among obese students, the smallest NNT was seen in the girl group aged 12-13 years (NNT=2.6, 95% CI =1.9-4.1), while the largest NNT in the boy group aged 14-18 years (NNT=5.9, 95% CI =4.7-8.1). The NNT of the girls aged 12-13 years was the smallest (NNT=2.7, 95% CI =2.2-3.5), and the NNT of the boys aged 14-18 years was the largest (NNT=7.4, 95% CI =6.0-9.7).@*Conclusion@#Health education at population level (health education lectures, official account push) with individual level (personalized dietary guidance) can effectively intervene overweight and obesity among middle school students in Guangzhou.
RESUMEN
Pancreatic cancer is a highly malignant tumor. PARP inhibitor (PARPI) is the first synthetic antineoplastic drug developed based on the concept of synthetic lethality and has been clinically approved for the treatment of ovarian cancer and breast cancer. Due to specific DNA repair defects, studies have found that tumors with BRCA1/2 germline mutations are sensitive to PARPI, but the specific mechanism of action is still unclear. A number of clinical trials for pancreatic cancer have been carried out. Phase III POLO studies have shown that Olaparib is effective and well tolerated as a maintenance treatment in patients with germline BRCA1/2 mutations and patients with metastatic pancreatic cancer after platinum-based induction chemotherapy. Clinical studies related to combination therapy suggest that the benefit of adding PARPI is likely to come from the maintenance phase of treatment. In general, PARPI has broad prospects in the treatment of pancreatic cancer.
