RESUMEN

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease(COPD) patients, and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease(COPD) patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management, and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat, mobile phone short message service(SMS)and telephone. Finally, a total of2 589 subjects were included in the analysis, including 1 300 in the intervention group and 1 289 in the control group. General demographic data, past medical history and family history of COPD, COPD related knowledge and practice survey, COPD related symptom assessment, acute onset, health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack, health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks, after intervention, the incidence of acute attacks in the intervention group was lower than that before intervention(χ2=52.901, P<0.001), and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention (P<0.001). WeChat had the best effect, decreasing the incidence by 14.4%, followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services, the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention (χ2=7.129, P=0.008), and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention (χ2=4.675, P<0.001). In terms of medical expenses, there was no significant difference between control group and intervention group with different intervention methods before intervention (P>0.05). After intervention, the difference between the control group and the intervention group with different intervention methods was statistically significant (H=11.864, P<0.05). The results of multiple comparisons showed that compared with the control group, the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group, and the difference was statistically significant (P<0.05). ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD, reduce the rate of consultation and medical expenses due to acute onset, and provide scientific basis for the basic COPD health management model.

RESUMEN

Objective To analyze the short-term survival and prognostic quality of life of patients with liver cirrhosis complicated by bacterial infection. Methods This study collected and analyzed 300 patients with liver cirrhosis complicated with infection who were hospitalized in the First Affiliated Hospital of Hebei North University, and followed up to discuss their survival and quality of life. Results In this study, the top two causes of infection were spontaneous bacterial peritonitis (60.67% of patients) and pneumonia (50.67% of patients). The second causes were urinary tract infections (15.33%), gastrointestinal infections (12.33%), and other causes. There was no statistically significant difference between male and female patients (P>0.05). In addition, the proportion of hospital infections was 71.00%, and there was no statistically significant difference between male and female patients (P>0.05). A total of 353 strains of pathogenic bacteria were isolated in this study (73.37% of patients with hospital infections). The distribution analysis of pathogenic bacteria showed that the highest proportion of ECO was 35.98%, followed by Klebsiella pneumoniae (18.98%). The distribution trend of 259 strains of pathogenic bacteria among hospital patients was consistent with that of all strains, and the difference was not statistically significant (P>0.05). Gram negative bacteria accounted for 79.60% (281/353) of all detected strains, of which Escherichia coli was mostly detected in patients with spontaneous bacterial peritonitis, Klebsiella Pneumoniae (KPN) and Pseudomonas aeruginosa (PAE) were mostly detected in patients with pneumonia, and Enterococcus (ENF) was mostly detected in patients with urinary tract infection; Among gram-negative bacteria, Staphylococcus epidermidis (SEP) and Staphylococcus aureus (SAU) are mostly found in patients with other infectious causes (blood flow infection, etc.) , and Streptococcus (STR) accounts for a high proportion in patients with Spontaneous bacterial peritonitis. In this study, 9 cases of death prognosis were detected during follow-up, and there was no statistically significant difference in the detection of death prognosis between different bacterial strains in both genders, as well as the difference in detection of death prognosis between hospital infections and out of hospital infections in both genders (P>0.05). There was no statistically significant difference in the detection of death prognosis between males and females due to different causes of infection, P>0.05. The quality of life scores of 291 surviving patients were compared between baseline and follow-up, indicating an increase in follow-up scores, especially in the dimensions of physiological function and physical pain. There was no statistically significant difference between different bacterial strains, infection causes, and hospital/non hospital infections (P>0.05) . Conclusion Spontaneous bacterial peritonitis and pneumonia are the main causes of infection that deserve special attention, and the main pathogens of infection are Gram negative bacteria. Targeted treatment and rehabilitation should be provided for patients with liver cirrhosis complicated by infection. At the same time, the proportion of hospital infections is relatively high, and attention should be paid to, prevention and control measures should be implemented as well.

Methods Data on the outbreak of varicella and vaccination in Chongqing from 2014 to 2020 were collected through the China Disease Prevention and Control Information System, and descriptive epidemiological methods were used for statistical analysis. Results A total of 181 551 cases of varicella were reported in Chongqing from 2014 to 2020, with an average annual incidence rate of 83.79 per 100 000. The incidence rate of varicella increased from 39.95 per 100 000 in 2014 to 81.88 per 100 000 in 2020 (P < 0.001). The incidence of varicella was seasonal, with the peak periods occurring from May to June and from October to December each year. The average annual incidence rate in municipal districts was 88.90/100 000, higher than 67.42/100 000 in counties and 82.50/100 000 in autonomous counties. The average annual incidence rate of varicella in males (87.13/100 000) was higher than that in females (80.38/100 000). The incidence of varicella was mainly distributed in people under 15 years old, with 143 508 cases (79.10%) reported, and the highest incidence age was 5-9 years old (37.00%). Among the affected occupations , 133 733 cases (62.6%) were students , 39 274 cases (18.40%) were children in nursery care, and 17 963 cases (8.4%) were scattered children. The actual number of doses of varicella vaccine from 2014 to 2020 was 2 302 522 doses, with the coverage rates of one-dose and two-dose vaccines being 75.56% and 32.17%, respectively. ARIMA predicted that there would be 2 604, 811, 756, 1 226, 2 405, 3 904, 2 410, 1 211, 2 034, 6 878, 10 887, and 8 955 cases of varicella from January to December 2021. Conclusion The incidence of varicella in Chongqing is on the rise, with obvious seasonal, regional and population distribution characteristics. It is necessary to strengthen the prevention and control of varicella epidemic, strengthen the prevention and control measures of key groups and key institutions in the high incidence season, strengthen the publicity of varicella vaccine, and improve the vaccination rate of two-doses of varicella vaccine for eligible children.

RESUMEN

ObjectiveTo examine the inhibitory effects of berberine compounds, including columbamine, on acetylcholinesterase from the perspectives of drug-target binding affinity and kinetics and explore the blood-brain barrier (BBB) permeability of these compounds in different multi-component backgrounds. MethodThe median inhibitory concentration (IC50) of acetylcholinesterase by berberine compounds including columbamine was measured using the Ellman-modified spectrophotometric method. The binding kinetic parameters (Koff) of these compounds with acetylcholinesterase were determined using the enzyme activity recovery method. A qualitative analysis of the ability of these components to penetrate the BBB and arrive at the brain tissue in diverse multi-component backgrounds (including medicinal herbs and compound formulas) was conducted using ultra performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). ResultBerberine compounds, including columbamine, exhibited strong inhibition of acetylcholinesterase, with IC50 values in the nanomolar range. Moreover, they displayed better drug-target binding kinetics characteristics (with smaller Koff values) than the positive control of donepezil hydrochloride (P<0.01), indicating a longer inhibition duration of acetylcholinesterase. Berberine components such as columbamine could penetrate the BBB to arrive at brain tissue in the form of a monomer, as well as in the multi-component backgrounds of Coptis and Phellodendri Chinensis Cortex medicinal extracts and the compound formula Huanglian Jiedutang. ConclusionThese berberine compounds such as columbamine exhibit a strong inhibitory effect on acetylcholinesterase and can arrive at brain tissue in multi-component backgrounds. In the level of pharmacological substance, this supports the clinical efficacy of compound Huanglian Jiedutang in improving Alzheimer's disease, providing data support for elucidating the pharmacological basis of compound Huanglian Jiedutang.

RESUMEN

ObjectiveTo investigate the role and mechanism of action of Yinchenhao Decoction in inhibiting ferroptosis of hepatocytes in mice with autoimmune hepatitis. MethodsA total of 18 specific pathogen-free female C57BL/6 mice were selected and divided into normal group, model group, and treatment group using a random number table, with 6 mice in each group. The mice in the model group and the treatment group were injected with concanavalin A (Con A) via the caudal vein to establish a mouse model of autoimmune hepatitis, and those in the normal group were injected with normal saline. The mice in the treatment group were given prophylactic treatment with Yinchenhao Decoction (4.68 g crude drug/kg) by gavage at 14 days before modeling, and Con A was injected after the last gavage. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), interferon gamma (IFN-γ), tumor necrosis factor-α (TNF-α), iron ion, glutathione (GSH), reactive oxygen species (ROS), adenosine triphosphate (ATP), and malondialdehyde (MDA) were measured; liver index and spleen index were calculated; the expression levels of GPX4 and SLC7A11 were measured; liver histopathological changes were compared between groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between three groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the normal group, the model group had significant increases in liver index, spleen index, ALT, AST, IFN-γ, TNF-α, iron ion, ROS and MDA (all P<0.05) and significant reductions in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 (all P<0.05). Compared with the model group, the treatment group had significant reductions in liver index, spleen index, ALT, AST, IFN-γ, TNF-α, iron ion, ROS and MDA (all P<0.05) and significant increases in the content of GSH and ATP and the protein expression levels of GPX4 and SLC7A11 (all P<0.05). HE staining showed that compared with the normal group, the model group showed massive hepatocyte degeneration and necrosis and inflammatory cell aggregation at the portal area, and compared with the model group, the treatment group had alleviation of liver necrosis and inflammatory infiltration. ConclusionLiver injury induced by Con A may be associated with ferroptosis. Yinchenhao Decoction can increase the protein expression levels of SLC7A11 and GPX4 protein and thus inhibit ferroptosis of hepatocytes induced by Con A.

RESUMEN

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine (TCM). The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology, Western medicine obstetrics and gynecology, and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion, the experts concluded that chromosome, endocrine, and immune abnormalities were the key factors for the occurrence of threatened abortion, and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion, TCM has advantages in preventing miscarriages, alleviating clinical symptoms and TCM syndromes, relieving anxiety, regulating reproductive endocrine and immune abnormalities, personalized and diversified treatment, enhancing efficiency and reducing toxicity, and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

RESUMEN

Oleanolic acid (OA), a pentacyclic triterpenoid, exhibits a broad spectrum of biological activities, including antitumor, antiviral, antibacterial, anti-inflammatory, hepatoprotective, hypoglycemic, and hypolipidemic effects. Since its initial isolation and identification, numerous studies have reported on the structural modifications and pharmacological activities of OA and its derivatives. Despite this, there has been a dearth of comprehensive reviews in the past two decades, leading to challenges in subsequent research on OA. Based on the main biological activities of OA, this paper comprehensively summarized the modification strategies and structure-activity relationships (SARs) of OA and its derivatives to provide valuable reference for future investigations into OA.

RESUMEN

Purpose: To analyze clinical manifestations, visual ability, and quality of life in pediatric uveitis and to explore factors affecting visual ability and quality of life. Methods: This cross?sectional study included 40 patients with pediatric uveitis in the database of Ophthalmology of Peking University First Hospital. All patients completed the Cardiff visual ability questionnaire for children (CVAQC) and pediatric quality of life inventory measurement models (PedsQL4.0). Results: A total of 40 cases (68 eyes) with pediatric uveitis were included in this study. Better visual acuity in the better eye was predictive of lower CVAQC, education, and distance vision scores. Better visual acuity in the worse eye was predictive of a lower CVAQC score and distance vision. Better CVAQC scores were predictive of lower PedsQL4.0, physical health, psychosocial health, and school functioning scores. Conclusion: Patients with pediatric uveitis tend to be seriously affected by ocular complications. The visual ability of patients with pediatric uveitis decreases significantly. Better visual acuity in the better eye is associated with better total visual ability, education, and distance vision. Better visual acuity in the worse eye is associated with better total visual ability and distance vision. Health?related quality of life is related to vision ability in pediatric uveitis

RESUMEN

AIM:To evaluate the changes in corneal biomechanics of patients with moderate refractive error after receiving small-incision lenticule extraction(SMILE)and femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)using the corneal visualization Scheimpflug technology(Corvis ST).METHODS:Prospective cohort study. A total of 65 moderate myopia patients(65 eyes)who were scheduled to undergo refractive surgery at the Ophthalmic Refractive Surgery Center of the Ningxia Eye Hospital from November 2020 to November 2021 were included in the study, and there were 30 eyes in the SMILE group and 35 eyes in the FS-LASIK group. The changes in corneal biomechanical parameters, including integrated radius(IR), inverse concave radius(ICR), deformation amplitude ratio 2mm(DAR2), stiffness parameter at first applanation(SP-A1), ambrosio relational thickness(ARTh)and the central curvature radius at highest concavity(HC-Radius)were observed by Corvis ST between both groups preoperatively and 1 and 3mo postoperatively.RESULTS: There were no statistical significance in biomechanical parameters between two groups of patients 1 and 3mo postoperatively(P&#x0026;#x003E;0.05). IR, ICR and DAR2 of each groups of patients 1 and 3mo postoperatively were significantly increased than those preoperatively, and SP-A1, ARTh and HC-Radius were significantly decreased than those preoperatively(all P&#x0026;#x003C;0.05). The biomechanical parameters at 1mo and 3mo postoperatively showed no statistical significance(P&#x0026;#x003E;0.05). In addition, a positive correlation was found between central corneal thickness(CCT)and ARTh and SP-A1 of the two groups of patients at 3mo postoperatively(FS-LASIK group: r=0.727, 0.819, SMLIE group: r=0.683, 0.434, all P&#x0026;#x003C;0.05), while a negative correlation was found between CCT and IR and ICR at 3mo postoperatively.(FS-LASIK group: r=-0.697, -0.622, SMLIE group: r=-0.447, -0.491, all P&#x0026;#x003C;0.05).CONCLUSION:For patients with moderate myopia, both SMILE and FS-LASIK can reduce corneal biomechanical stability. Both surgeries showed no significant differences in the effect on biomechanical, and the biomechanical has been stabilized at 1mo postoperatively. A correlation was found between postoperative CCT and ARTh, SP-A1, IR and ICR.

RESUMEN

Chronic kidney disease is characterized by renal structural damage and dysfunction (for over three months) caused by various factors. In traditional Chinese medicine, chronic kidney disease can be classified as edema, ischuria, consumptive disease, and anuria and vomiting. The pathogenesis of chronic kidney disease is frequently attributed to the deficiency of lung, spleen and kidney, dampness combined with stasis, and accumulation of turbid toxin. Huaiqihuang granules are a Chinese patent medicine composed of Vanderbylia robiniophila, Lycii Fructus, and Polygonati Rhizoma, with diverse pharmacological effects such as improving immunity and protecting kidney function. It is widely used in the treatment of cancer, chronic kidney disease, and respiratory system diseases. The available studies have demonstrated that Huaiqihuang granules can intervene in the progression of chronic kidney disease via various ways, such as protecting glomerular podocytes, inhibiting the proliferation of glomerular mesangial cells, resisting renal interstitial fibrosis, alleviating renal inflammation and oxidative stress, and regulating renal cell apoptosis and the immune system function. The clinical application of Huaiqihuang granules is based on conventional treatment and has achieved remarkable effects in the treatment of children's nephrotic syndrome, diabetic nephropathy, nephritis of Schonlein-Henoch purpura, IgA nephropathy, and chronic renal failure. Scholars have achieved great progress in the research on the mechanism and the clinical application of Huaiqihuang granules in the treatment of chronic kidney disease. However, the detailed summary of the progress in recent years remains to be carried out. Therefore, this paper reviewed the available studies in this field, aiming to provide a reference for the comprehensive and extensive clinical application of Huaiqihuang granules in the treatment of chronic kidney disease.

RESUMEN

ObjectiveTo investigate the mechanism of icariin in ameliorating efferocytosis dysfunction and inflammatory response of alveolar macrophages induced by cigarette smoke extract via the peroxisome proliferator-activated receptor gamma (PPARγ) signaling pathway. MethodThe untreated rat alveolar macrophages (NR8383) were taken as the blank group. The NR8383 cells treated with 10% cigarette smoke extract were divided into model, low-, medium-, and high-dose (10, 20, 40 μmol·L-1) icariin, PPARγ inhibitor, and PPARγ inhibitor + low-, medium-, and high-dose icariin groups. Alamar blue colorimetry was employed to examine the proliferation and toxicity of icariin on NR8383 cells. The efferocytosis rate of NR8383 cells was detected by flow cytometry. Enzyme-linked immunosorbent assay was employed to measure the levels of tumor necrosis factor-alpha (TNF-α), transforming growth factor-β1 (TGF-β1), and milk fat globule-epidermal growth factor 8 (MFG-E8). Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) were employed to determine the protein and mRNA levels, respectively, of PPARγ, CD36, and RAS-related C3 botulinum toxin substrate 1 (Rac1). ResultThe efferocytosis dysfunction model of NR8383 was established with the cigarette smoke extract. Compared with the blank control group, the model group showed decreased efferocytosis rate (P<0.05), elevated TNF-α level (P<0.05), lowered TGF-β1 and MFG-E8 levels (P<0.01), and down-regulated mRNA and protein levels of PPARγ, CD36, and Rac1 (P<0.05, P<0.01). Compared with the model group, the treatment with icariin increased the efferocytosis rate (P<0.05, P<0.01), lowered the TNF-α level (P<0.01), elevated TGF-β1 and MFG-E8 levels (P<0.05), and up-regulated the protein and mRNA levels of PPARγ, CD36, and Rac1 (P<0.05, P<0.01). Compared with icariin alone, PPARγ inhibitor + icariin decreased the efferocytosis rate (P<0.05) and down-regulated the protein and mRNA levels of PPARγ (P<0.05, P<0.01). In addition, PPARγ inhibitor + low-dose icariin down-regulated the protein level of CD36 (P<0.01) and PPARγ inhibitor + low-/medium-dose icariin up-regulated the protein level of Rac1 (P<0.05). ConclusionIcariin ameliorates the cigarette smoke extract-induced efferocytosis dysfunction of alveolar macrophage by regulating the PPARγ signaling pathway and cytoskeletal structure rearrangement.

RESUMEN

@#According to the needs of CT image evaluation for transapical transcatheter aortic valve replacement (TAVR), 20 clinical questions were proposed by the Delphi method, 15 questions were initially determined, and 12 clinical questions were summarized and determined by domestic experts. PubMed, Web of Science, Wanfang, and CNKI databases were searched by computer to collect the relevant literature from inception to November 2022, and finally 53 studies were included. Based on evidence-based study and evaluation experience, 3 meetings were held to give recommendations for preoperative CT data acquisition method, preoperative imaging evaluation of aortic root, imaging evaluation of transapical approach, preoperative auxiliary guidance of TAVR by CT images combined with 3D printing, and postoperative imaging evaluation of transapical TAVR, hoping to promote the standardized and successful development of transapical TAVR in China.
