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.

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.

Objective To analyze the epidemic characteristics of varicella in Chongqing from 2014 to 2020, and to provide evidence for the development of scientific and effective varicella control strategies. 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.

MethodFrom January 2019 to July 2022, 90 patients in the department of Traditional Chinese medicine(TCM) of Beijing Jishuitan Hospital who met the inclusion criteria were selected and divided into two groups according to the random number table, with 45 patients in each group. During the study, 19 cases dropped out, with 41 cases included in the final observation group and 30 cases in the control group. The observation group was given Rongjin Tongbi decoction orally, and the control group was given Loxoprofen Sodium Tablets orally for 28 days. The differences in the visual analog scale (VAS) scores, the Japanese Orthopaedic Association (JOA) scores, activities of daily living (ADL) assessments, TCM clinical symptoms, subjective symptoms, and clinical signs scores between two groups before and after treatment were observed. Liver and kidney functions and gastrointestinal adverse reactions were detected for safety evaluation. ResultBefore treatment, there was no statistically significant difference in scores between the observation group and the control group. After treatment, the absolute values of the differences in VAS and ADL scores in the observation group were higher than those in the control group (P<0.05). There was no statistically significant difference in the absolute value of the difference in JOA scores between two groups. The absolute value of the difference in TCM clinical symptom scores in the observation group was higher than that in the control group (P<0.01). There was no statistically significant difference in the absolute values of the differences in subjective symptom and clinical sign scores between two groups. The levels of liver and kidney function indicators in both groups before and after the experiment were normal, and there was no significant difference in gastrointestinal reactions. ConclusionRongjin Tongbi decoction can significantly improve the symptoms of sciatica patients caused by lumbar intervertebral disc herniation with liver and kidney deficiency type.

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

Objective With the deepening of population aging, sarcopenia has become an important public health problem affecting the health and quality of life of the elderly population. As the end-product of purine metabolism in human body, uric acid has dual effects of anti-oxidation, pro-oxidation and pro-inflammatory reaction , which affects the occurrence and development of sarcopenia to a certain extent. This paper reviews the research progress of serum uric acid and sarcopenia. Methods PubMed database, Web of Science core collection database, Embase database, China National Knowledge Infrastructure (CNKI) and Wanfang database were searched for literatures on the relationship between serum uric acid (SUA) level and sarcopenia up to February 7, 2022, and then reviewed. Results A total of 4 epidemiological studies were found on serum uric acid levels and the risk of sarcopenia. Among them, 3 studies found that SUA within a certain level range was a protective factor for sarcopenia, and 1 study suggested that the risk of sarcopenia increased with the increase of SUA levels. There was a gender difference between serum uric acid level and sarcopenia risk. Conclusion At present, the results of studies on the relationship between serum uric acid levels and the risk of sarcopenia are still controversial, which may be caused by the different effects of uric acid in human body. In the future , more extensive and in-depth studies are needed to investigate the relationship between the two.

RESUMEN

To evaluate the implementation of Survey of oncomelanid snails (WS/T 563—2017) in schistosomiasis-endemic foci, two schistosomiasis-endemic counties were selected from two provinces of Sichuan and Anhui. Professional staff working in province-, city-, county- and township-level disease control and prevention institutions, parasitic disease control institutions or medical institutions were recruited, and the understanding, use and implementation of Survey of oncomelanid snails (WS/T 563—2017) were investigated using questionnaires and interviews. The awareness, use, proportion of propagation and implementation and correct rate of answering questions pertaining to Survey of oncomelanid snails (WS/T 563—2017) were analyzed. A total of 270 questionnaires were allocated, and 269 were recovered, including 254 valid questionnaires. The overall awareness of Survey of oncomelanid snails (WS/T 563—2017) was 84.64% (215/254), and propagation and implementation of Survey of oncomelanid snails (WS/T 563—2017) was not performed in 23.28% (17/73) of the survey institutions following implementation of Survey of oncomelanid snails (WS/T 563—2017), with meeting training and allocation of propagation materials as the main type of propagation and implementation. Among 254 respondents, 77.16% (196/254) were familiar with the standard, 66.14% (168/254) understood the conditions for use of the standard during snail surveys, and 96.85% (246/254) had the approach for identifying snails. In addition, there were 41.73% (106/254), 50.78% (129/254) and 7.48% (19/254) of respondents that considered the operability of Survey of oncomelanid snails (WS/T 563—2017) was very good, good and general, respectively. The findings demonstrate that the issue and implementation of Survey of oncomelanid snails (WS/T 563—2017) has filled the gap for the standardization of snail control techniques, and which plays an importang guiding role in the national schistosomiasis control program.

RESUMEN

Objective To investigate the prevalence and epidemiological characteristics of taeniasis and cysticercosis among residents in Tibetan agricultural areas of Sichuan Province, so as to provide insights for the prevention and control of taeniasis and cysticercosis. Methods From 2016 to 2022, Kangding City, Daocheng County, Derong County, Ruoergai County and Muli Tibetan Autonomous County were sampled from Tibetan agricultural areas of Ganzi Tibetan Autonomous Prefecture, Aba Tibetan and Qiang Autonomous Prefecture and Liangshan Yi Autonomous Prefecture in Sichuan Province, and 1 to 6 townships were sampled from each county (district), followed by 4 to 7 villages sampled from each township. Primary school children were sampled using a cluster sampling method, and permanent residents at ages of over 16 years were randomly sampled from each village. Participants’ demographics, history of tapeworm excretion during the past year and clinical symptoms and signs of cysticercosis were collected through questionnaire surveys, and participants’ stool and venous blood samples were collected. Taenia eggs were detected in stool samples using the direct smear method, and deworming was performed among taeniasis patients with areca nut-squash seeds. The tapeworm species were identified using a multiplex PCR assay, and serum specific IgG antibody against cysticercus was detected using enzyme-linked immunosorbent assay (ELISA). Results A total of 5 249 respondents participated in the questionnaire survey, including 603 respondents (11.5%) with a self-reported history of proglottids secretion during the past year. A total of 3 976 residents were subjected to stool examinations, and the detection of Taenia eggs was 6.5%. Of 258 participants undergoing deworming, there were 403 cases (94.2%) with excretions of Taenia worms or proglottids. The mean prevalence of taeniasis was 10.9% (439/4 043), and there were gender-, age- and region-specific prevalence rates of taeniasis (χ2 = 36.73, 126.31 and 163.41, all P values < 0.05). Multiplex PCR assays detected 41 cases with T. solium infections (12.5%), 197 cases with T. saginata infections (59.9%) and 91 cases with T. asiatica infections (27.6%) among 329 patients undergoing deworming, and there were region-specific prevalence rates of T. solium, T. saginata and T. asiatica infections (χ2 = 45.39, P < 0.05). In addition, the sero-prevalence of anti-cysticercus IgG antibody was 7.0% (345/4 933), and there were age- and region-specific sero-prevalence rates of anti-cysticercus IgG antibody (χ2 = 13.49 and 51.76, both P values < 0.05). Conclusions Multiple Taenia species are prevalent in Tibetan agricultural areas of Sichuan Province and the sero-prevalence of anti-cysticercus antibody is high among residents. Monitoring and control of taeniasis and cysticercosis should be strengthened.

RESUMEN

Objective To analyze the epidemiological characteristics of newly reported advanced schistosomiasis cases in Sichuan Province, so as to provide the evidence for analyzing the causes and formulating targeted control measures of newly reported advanced schistosomiasis cases. Methods Individual case investigation forms for advanced schistosomiasis cases were collected from the Sichuan Provincial Epidemic Annual Report System from 2011 to 2022, and patients’ demographics, previous medical history and liver parenchymal grading were retrieved. All advanced schistosomiasis cases’ medical records were reviewed, and the subtypes of schistosomiasis-endemic villages where the cases’ household registration were, floating population, survival and death and time of death were collected. Results A total of 321 newly reported advanced schistosomiasis cases were found in Sichuan Province from 2011 to 2022, with a male to female ratio of 0.99 to 1. There were 274 cases at ages of over 50 years (85.4%), with the highest proportion seen at ages of 60 to 69 years (87 cases, 27.1%), and splenomegaly was the most common type (180 cases, 56.1%), with no dwarfism type detected. The highest number of cases was reported in 2011 (78 cases), followed by in 2022 (74 cases), and the highest number of cases were reported in Meishan City (199 cases, 62.0%), Dongpo District (131 cases, 40.8%), and hilly subtype areas (136 cases, 42.4%). As of the end of 2022, there were 111 deaths due to advanced schistosomiasis, with the highest number of deaths seen in 2018 (25 deaths), and the highest mortality was seen among patients with the ascites type (41.2%). There were 47 (37.3%), 40 (59.5%) and 4 (23.5%) cases with grade III liver parenchyma among patients with splenomegaly, ascites, and colonic proliferation types, respectively, and there was a significant difference in the grading of III liver parenchyma among three types of patients (H = 12.092, P < 0.05), with more severe liver parenchyma injuries seen among patients with the ascites type than among those with splenomegaly and colonic proliferation type (Z = 24.262 and 44.738, both Padjusted values < 0.05). Conclusions There have been newly reported advanced schistosomiasis cases in Sichuan Province during recent years, and patients with the ascites type should be given a high priority among advanced schistosomiasis cases in Sichuan Province. Intensified clue surveys are needed for early identification and treatment of advanced schistosomiasis cases, so as to increase the survival rate and improve the quality of life.
