RESUMO
BACKGROUND: Recent clinical trials have evaluated the efficacy of vonoprazan-amoxicillin (VA) dual therapy as the first-line treatment for Helicobacter pylori infection in different regions with inconsistent results reported. In this systematic review and meta-analysis, we aimed to evaluate the efficacy of VA dual therapy compared to the currently recommended therapy for eradicating H. pylori. MATERIALS AND METHODS: A comprehensive search of the PubMed, Cochrane, and Embase databases was performed using the following search terms: ("Helicobacter" OR "H. pylori" OR "Hp") AND ("vonoprazan" OR "potassium-competitive acid blocker" OR "P-CAB") AND ("amoxicillin" OR "penicillin") AND ("dual"). The primary outcome was to evaluate the eradication rate according to intention-to-treat and per-protocol analysis. The secondary outcomes were adverse events and compliance. RESULTS: A total of 15 studies involving 4, 568 patients were included. The pooled eradication rate of VA dual therapy was 85.0% and 90.0% by intention-to-treat and per-protocol analysis, respectively. The adverse events rate and compliance of VA dual therapy were 17.5% and 96%, respectively. The efficacy of VA dual therapy was superior to proton pump inhibitors-based triple therapy (82.0% vs. 71.4%, p < 0.01) but lower than vonoprazan-containing quadruple therapy (83.1% vs. 93.3%, p = 0.02). 7-day VA dual therapy showed lower eradication rates than 10-day (χ2 = 24.09, p < 0.01) and 14-day VA dual therapy (χ2 = 11.87, p < 0.01). The adverse events rate of VA dual therapy was lower than vonoprazan triple therapy (24.6% vs. 30.9%, p = 0.01) and bismuth-containing quadruple therapy (20.5% vs. 47.9%, p < 0.01). No significant difference of compliance was observed between VA dual therapy and each subgroup. CONCLUSION: VA dual therapy, a novel regimen, showed high efficacy as the first-line treatment for H. pylori eradication, which should be optimized before application in different regions.

OBJECTIVES: To study the efficacy of bronchoalveolar lavage (BAL) combined with prone positioning in children with Mycoplasma pneumoniae pneumonia (MPP) and atelectasis and its effect on pulmonary function. METHODS: A prospective study was conducted on 94 children with MPP and atelectasis who were hospitalized in Ordos Central Hospital of Inner Mongolia from November 2020 to May 2023. The children were randomly divided into a treatment group and a control group, with 47 children in each group. The children in the treatment group were given conventional treatment, BAL, and prone positioning, and those in the control group were given conventional treatment and BAL. The two groups were compared in terms of fever, pulmonary signs, length of hospital stay, lung recruitment, and improvement in pulmonary function. RESULTS: Compared with the control group, the treatment group had significantly shorter time to improvement in pulmonary signs and length of hospital stay and a significantly higher rate of lung recruitment on day 7 of hospitalization, on the day of discharge, and at 1 week after discharge (P<0.05). Compared with the control group, the treatment group had significantly higher levels of forced vital capacity (FVC) as a percentage of the predicted value, forced expiratory volume (FEV) in 1 second as a percentage of the predicted value, ratio of FEV in 1 second to FVC, forced expiratory flow at 50% of FVC as a percentage of the predicted value, forced expiratory flow at 75% of FVC as a percentage of the predicted value, and maximal mid-expiratory flow as a percentage of the predicted value on the day of discharge and at 1 week after discharge (P<0.05). There was no significant difference in the time for body temperature to return to normal between the two groups (P>0.05). CONCLUSIONS: In the treatment of children with MPP and atelectasis, BAL combined with prone positioning can help to shorten the time to improvement in pulmonary signs and the length of hospital stay and promote lung recruitment and improvement in pulmonary function.

INTRODUCTION: Our previous study has proofed the glucose sensitive gene-thioredoxin-interacting protein (TXNIP) expression was up in the placenta of the patients with gestational diabetes mellitus (GDM), but the pathological mechanisms underlying abnormal TXNIP expression in the placenta of patients with GDM is completely unclear and additional investigations are required to explain the findings we have observed. In the present study, we simulated the high TXNIP expression via introducing the Tet-On "switch" in vitro, approximate to its expression level in the real world, to explore the following consequence of the abnormal TXNIP. METHODS: The expression and localization of TXNIP in the placenta of GDM patients and the health control was investigated via immunofluorescent staining, western blot and RT-qPCR. Overexpression of TXNIP was achieved through transfecting Tet-on system to the human trophoblastic cell line-HTR-8/Svneo cell. TXNIP knockout was obtained via CRISPR-Cas9 method. The cell phenotype was observed via IncuCyte Imaging System and flow cytometry. The mechanism was explored via western blot and RT-qPCR. RESULTS: The expression level of TXNIP in the GDM placenta was nearly 2-3 times higher than that in the control. The TXNIP located at trophoblastic cells of the placenta. When the expression of TXNIP was upregulated, the migration and invasion of the cells accelerated, but cell apoptosis and proliferation did not changed compared with the control group. Furthermore, the size of the TetTXNIP cells became larger, and the expression level of Vimentin and p-STAT3 increased in the TetTXNIP cells. All the changes mentioned above were opposite in the TXNIP-KO cells. CONCLUSIONS: Abnormal expression of TXNIP might be related to the impairment of the GDM placental function, affecting the migration and invasion of the placental trophoblast cells through STAT3 and Vimentin related pathway; thus, TXNIP might be the potential therapeutic target for repairing the placental dysfunction deficient in GDM patients.

BACKGROUND AND AIMS: The validity of high uric acid levels as an independent cause of stroke remains controversial, and the association between its low concentration and stroke is unclear. This study determines how different serum uric acid (SUA) levels are associated with stroke risk. METHODS: This cross-sectional study used continuous National Health and Nutrition Examination Survey data in the United States during 1999-2020. The SUA levels of 6.0, 6.8, and 9.0 mg/dL were all considered as cut-off points. Restricted cubic spline interpolation and logistic regression models were used to evaluate the different associations. Subgroup analyses and sensitivity analyses were conducted to evaluate the influence of multiple factors on the outcomes. RESULTS: The study included 23,413 participants aged ≥ 20 years. A J-shaped curve existed between SUA and stroke risk, and the risk of stroke was positively correlated with SUA levels in the overall population. Subgroup analysis of all adults in the SUA 6.8-9.0 mg/dL group showed that stroke risk for non-Hispanic white, obese, ex-smoker, and heavy drinking groups was increased, but for the other Hispanic group was reduced. In the SUA < 6.0 mg/dL group, stroke risk for ex-smoker, heavy drinkers, and no chronic kidney disease groups was increased. CONCLUSION: Our findings indicate a J-shaped relationship between SUA levels and stroke risk. Low and high SUA levels increased stroke risk for different populations, except in the other Hispanic population. Early SUA management is highly significant for stroke prevention in high-risk populations.

Helicobacter pylori is closely related to chronic gastritis. The aim of the study was to investigate the correlation between H. pylori virulence genes and chronic gastritis in order to determine the pathogenic role of H. pylori virulence genes in chronic gastritis. Gastric mucosal tissues were obtained from 142 patients with chronic gastritis at three Beijing hospitals. The presence of virulence genes was determined by polymerase chain reaction (PCR) from H. pylori DNA. Multilocus sequence typing (MLST) and a phylogenetic tree were performed to characterize the overall genetic diversity. 91 new sequence types were identified by MLST in this study, and all strains showed high genetic diversity. The H. pylori isolates were divided into three types: hspEAsia strains (61 strains), hpEurope strains (15 strains), and mixed strains (16 strains). Some virulence genes were found to be significantly different between strains. The highest positive rates were found for dupA in chronic atrophic gastritis (AG), iceA1 in chronic non-atrophic gastritis with erosions, and iceA2 in chronic non-atrophic gastritis. The presence of dupA was found to be inversely related to the risk of AG. The H. pylori strains display high genetic diversity. Some virulence genes were found to be significantly different between diseases. The detection of various virulence genes is critical for screening high-risk populations for precancerous lesions and for the early prevention and control of gastric cancer.

Tomato (Solanum lycopersicum L.), as one of the most economically important and highly nutritious vegetable crops across the world, is widely cultivated in China, one of the largest tomato-concuming countries in the world (Ye et al., 2020; Wang and Liu, 2021). At present, major bacterial diseases in tomato include bacterial speck disease, tomato bacterial wilt and bacterial canker, all of which affect the tomato production around the world (Rosli et al., 2021; Peritore-Galve et al., 2021; Wang et al., 2022). In April 2022, a new bacterial disease was discovered on leaves, stems and fruits of tomato in a farmer's greenhouse located in Longfeng District in DaQing (125°07`-125°15`E, 46°28`-46°32`N), Heilongjiang Province, China. This field had tomato disease incidences approximately 50%. Apparent brown discolorations were found on fruits, leaves and stems in tomato plants. Symptoms were similar to fungal brown spots caused by Phytophthora infestans of tomato (Zhi et al.,2021; Liu et al.,2021) (Supplementary Figure S1). To isolate and identify the pathogen, the tissues of infected fruits, leaves and stems with typical symptoms were excised from diseased plants separately, and were disinfected with 75% ethanol for 10 s followed by 2% NaClO for 3 min and then washed five to eight times with sterile water (Wang et al., 2017). Afterwards, the samples were plated on nutrient agar (NA) solid medium and incubated. After incubation at 30°C for 2-3 days, bacterial colonies were isolated, then purified on nutrient agar (NA) solid medium at least twice by a streak plate method (Dou et al., 2019; Li et al, 2021; Zhao et al., 2022). White colonies grew on the NA medium after incubating for 2 days, showing round, opaque and smooth, which was similar to characteristics described as Enterobacter cloacae (García-González et al., 2018; Li et al, 2021). To further confirm the speculation on the identity of the isolated bacterium, the fragments of 16S rRNA were amplified and sequenced. The sequence of 16S rRNA was uploaded into GeneBank with accession numbers (OP077195.1). BLAST analysis of the sequence showed 97.68% identity with one corresponding sequence of E. cloacae in GeneBank (namely MK937637.1). Furthermore, a phylogenetic tree based on the sequence of 16S rRNA gene revealed that the isolate was grouped in the same clade as E. cloacae (Supplementary Figure S2). Based on Koch postulates to test pathogenicity of isolated bacteria, bacteria were inoculated on 30 day-old healthy tomato plants with three leaves stages, and the re-isolation of bacteria were carried out after 2 days of inoculation. To confirm pathogenicity, the isolates were cultured on LB medium at 30â for 2 days to prepare suspensions and adjusted to an optical density (OD) of 0.2 at A600, with a final concentration of 1â ¹108 CFU/ml. Eight potted tomato plants were sprayed with bacteria suspensions, and eight control potted plants were sprayed with sterile distilled water. These seedlings were incubated in a chamber at 30°C with a 12 h light/dark photoperiod, with 85% relative humidity. After 2 days, inoculated tomato seedlings showed irregular small spots in leaves and brown necrosis at blade tips, and 8 to 10 days later, the leaves of tomato plants browned and died. The symptoms were the same with those of the initial diseased leaves of tomato plants (Supplementary Figure S1). No symptoms were observed on the control leaves (Supplementary Figure S3). Pathogenicity tests were repeated three biological times with same results. Meanwhile, the bacteria strains were re-isolated from symptomatic inoculated seedlings and confirmed as E. cloacae by culture and sequence methods as above. In China, there are no detailed records about the causal agent of this disease on tomato in a published paper in Chinese and English. To our knowledge, this is the first report of Enterobacter leaf brown necrosis caused by E. cloacae on tomato in China. Those results are of great significance for the production and management of tomato in greenhouse and control of the disease.
RESUMO
Drug instructions,the statutory and technical documents recording effectiveness and safety information,are an important basis for guiding doctors,pharmacists,and patients to use drugs rationally,and their scientificity,standardization,and accuracy directly affect the medication safety of the public. The sections of adverse drug events,contraindications,precautions,warnings,and application for specific populations in drug instructions directly express safety information and measures for rational use of drugs. In the drug life cycle,marketing authorization holders( MAHs) need to update safety information in the instructions promptly to ensure the safety and effectiveness of clinical drug medication. At present,revising instructions is an important measure to control drug risks. In the drug life cycle,in order to standardize the revision of safety information in the instructions by MAHs and eliminate inexact terms such as " unclear",the Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,have been established under the guidance of Standardization Department,China Association of Chinese Medicine. Therefore,on the basis of the existing rules and regulations,the standardized technical procedures for revising instructions came into being to help clinical safe and rational medication of drugs,and implement the strategy of " Healthy China".

Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,were proposed by Professor ZHANG Bing from Research Center for Pharmacovigilance and Rational Use of Traditional Chinese Medicine,and underwent centralized management by Chinese Association of Chinese Medicine. They were officially released on July 23 and implemented on July 31,2021. The series of group standards consist of six sections,including general principles,adverse drug events,contraindications,precautions,application for special populations,and warnings. The section of general principles is comprised of holistic and programmatic expressions,which explain the general technical requirements for revising the marketed Chinese patent medicine instructions. The other five sections focus on information collection,screening,transformation,and illustration of specific items,forming a standardized revision technical process. This series of standards is the result of multiple rounds of research and the suggestions of more than 200 experts in different professional fields of " medicine-pharmacy-management-law-enterprise" have been gathered therein to reach a consensus. With the purposes of establishing standardized technical specifications for the revision of safety information in the marketed Chinese patent medicine instructions,guiding marketing authorization holders in revising the instructions,filling the gaps in the research of Chinese patent medicine instructions,promoting the deve-lopment of pharmaceutical care and academic research,and encouraging the rational and safe medication of Chinese patent medicine,the series of group standards is of great significance.

BACKGROUND: Body mass index (BMI) is an accepted measurement that is widely used to quantify overweight and obesity at the population level. Previous studies have described the distribution variation of BMI through applying common statistical approaches, such as multiple linear or logistic regression analyses. This study proposed that associations between BMI and socioeconomic characteristics, diet, and lifestyle factors varied across the conditional BMI distribution. METHODS: This study was based on a sample of 10,023 Chinese adults who participated in the monitoring of chronic diseases and associated risk factors in Shaanxi Province, Northwest China, in 2013. Cross-quantile factors were observed in the relationships between major risk factors and BMI through quantile regression (QR) and ordinary least squares (OLS) regression. RESULTS: Participants' mean BMI was 24.19 ± 3.51 kg/m2 (range 14.33-52.82 kg/m2). The QR results showed that living in urban areas was associated with BMI in the low and central quantiles (10th-60th). Participants with 6-9 years of education were 0.23-0.38 BMI units higher in the first half of the BMI quantiles compared with those with ≤6 years of education. There was a positive association between consumption of red meat and BMI; however, the association diminished from the 10th to the 50th quantile. Intake of oil and alcohol were positively associated with all BMI quantiles. Cigarette smoking per day was negatively associated with BMI, which showed a U-shaped distribution. The above results were also observed in the OLS. CONCLUSION: This study implies that in addition to socioeconomic characteristics, limiting oil and alcohol intake may decrease BMI score. Consuming more red meat could be a strategy to increase BMI.

The outbreak of emerging infectious pneumonia caused by 2019 Novel Coronavirus (2019-nCoV) has posed an enormous threat to public health, and traditional Chinese medicine (TCM) have made vast contribution to the prevention, treatment and rehabilitation of coronavirus disease 19 (COVID-19) among Chinese population. As an indispensable part of TCM, Chinese patent medicines (CPMs) are highly valued and critically acclaimed in their campaign to contain and tackle the epidemic, they can achieve considerable effects for both suspected cases under medical observation period, and confirmed individuals with serious underlying diseases or critical conditions. Given this, based on the Guideline on Diagnosis and Treatment of Coronavirus Disease 2019 in China, the present review summarized the basic information, clinical evidence and published literatures of recommended CPMs against COVID-19. The details were thoroughly introduced involving compositions, therapeutic effects, clinical indications, medication history of CPMs and the profiles of corresponding research. With regard to infected patients with different stages and syndrome, the preferable potentials and therapeutic mechanism of CPMs were addressed through the comprehensive collection of relevant literatures and on-going clinical trials. This study could provide an insight into clinical application and underlying mechanism of recommended CPMs against COVID-19, with the aim to share the Chinese experience in clinical practice and facilitate scientific development of TCM, especially CPMs in the fierce battle of COVID-19.

Soil erosion, which has been recently shown to significantly perturb carbon cycling, occurs naturally but can be either enhanced or reduced by human activities. However, the impacts of soil erosion on terrestrial contaminant cycles remain unclear. Here, we select eight trace elements, i.e., arsenic, cadmium, chromium, copper, nickel, lead, zinc, and mercury, to examine the erosional impacts of the elements' fate and transport across China. By synthesizing the detailed distribution of soil erosion fluxes, soil element inventories, and diverse modeling methods, we reveal that while human activities have reduced the lateral transport of these elements in the Loess Plateau (Central North China, a 56% decline in the past two decades with a range of 46% to 110%) due to soil conservation projects, they have increased these transport fluxes in China's major karst regions (Southwest China, a 84% increase with a range of 55% to 150%) because of severe rocky desertification. These fluxes have completely overwhelmed the soil conservation efforts in the Loess Plateau. Fluxes of these elements into aquatic environments from Southwest China reached 46% of the total input in China in 2010. These fluxes were higher than the inputs from point sources in the region by a factor of 50 because of impacts of excessive agricultural cultivation and geographical and climatic factors. These findings indicate the enormous perturbation of terrestrial contaminant cycles caused by soil erosion in karst regions and demonstrate the need for long-term sustainable management of soil erosion and contaminant discharge to protect fragile terrestrial ecosystems.

AIM: The present study was performed to investigate the effect of Aesculus hippocastanum (AH; Venoplant®) on concanavalin A (ConA)-induced acute liver injury and explore the mechanism in mice. METHODS: ConA (20 mg/kg) was administered via tail vein injection to induce hepatic damage. The groups of AH (Venoplant®) were given at 65.8, 131.6, and 263.2 mg/kg by oral gavages for 20 days. The serum levels of aspartate transaminase (AST), alanine aminotransferase (ALT), total protein (TP), and albumin (Alb) were determined by automatic biochemical analyzer, and the Alb/globulin (A/G) ratio was calculated. Tumor necrosis factor-α (TNF-α) and IFN-γ levels were assayed by enzyme-linked immunosorbent assay. The liver tissue was attained by hematoxylin and eosin, and the histopathological changes were calculated. The cell apoptosis was assayed by terminal dUTP nick-end labeling. The malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione (GSH) content of liver tissue were assayed by related kits. The activity of caspase-3 was detected by spectrophotometry. The expressions of cytochrome c, Bax, Bcl-2, c-Jun N-terminal kinase (JNK), and p-JNK were detected by western blot. RESULTS: The results showed that the levels of ALT, AST, IFN-γ, and TNF-α in AH (Venoplant®) groups were significantly lower than those in ConA-injured group, while the levels of TP, Alb, and A/G were significantly higher. The SOD and GSH levels were significantly increased, and the MDA level was decreased; liver histopathology was changed consistently with the serological indicators, AH (Venoplant®) treatment significantly reduced the pathological damage and cell apoptosis; while in AH (Venoplant®) group, the expressions of cytochrome c, caspase-3, Bax/Bcl-2 ratio, and p-JNK were significantly decreased. CONCLUSION: AH (Venoplant®) could significantly protect the ConA-induced acute liver injury in mice via inhibition of reactive oxygen species and JNK pathway.

Terrestrial mercury (Hg) transport, induced by water erosion and exacerbated by human activities, constitutes a major disturbance of the natural Hg cycle, but the processes are still not well understood. In this study, we modeled these processes using detailed information on erosion and Hg in soils and found that vast quantities of total Hg (THg) are being removed from land surfaces in China as a result of water erosion, which were estimated at 420 Mg/yr around 2010. This was significantly higher than the 240 Mg/yr mobilized around 1990. The erosion mechanism excavated substantial soil THg, which contributed to enhanced Hg(0) emissions to the atmosphere (4.9 Mg/yr around 2010) and its transport horizontally into streams (310 Mg/yr). Erosion-induced THg transport was driven by the extent of precipitation but was further enhanced or reduced by vegetation cover and land use changes in some regions. Surface air temperature may exacerbate the horizontal THg release into water. Our analyses quantified the processes of erosion-induced THg transport in terrestrial ecosystems, demonstrated its importance, and discussed how this transport is impacted by anthropogenic inputs and legacy THg in soils. We suggest that policy makers should pay more attention to legacy anthropogenic THg sources buried in soil.

BACKGROUND: Everolimus -eluting stent (EES) is common used in patients undergoing percutaneous coronary interventions (PCI). Our purpose is to evaluate long-term clinical outcomes of everolimus -eluting stent (EES) versus paclitaxel-eluting stent (PES) in patients undergoing percutaneous coronaryinterventions (PCI) in randomized controlled trials (RCTs). METHODS: We searched Medline, EMBASE, Cochrane Library, CNKI, VIP and relevant websites ( https://scholar-google-com.ezproxy.lib.usf.edu/ ) for articles to compare outcomes between everolimus-eluting stent and paclitaxel-eluting stent without language or date restriction. RCTs that compared the use of everolimus -eluting stent and paclitaxel-eluting stent in PCI were included. Variables relating to patient, study characteristics, and clinical endpoints were extracted. Meta-analysis was performed using RevMan 5.2 software. RESULTS: We identified 6 published studies (from three randomized trials) more on everolimus-eluting stent (n = 3352) than paclitaxel-eluting (n = 1639), with follow-up duration ranging from 3, 4 and 5 years. Three-year outcomes of everolimus-eluting stent compared to paclitaxel-eluting were as following: the everolimus-eluting stent significantly reduced all-cause death (relative risk [RR]:0.63; 95% confidence interval [CI]: 0.46. to 0.82), MACE (RR: 0.56; 95% CI: 0.41 to 0.77), MI (RR: 0.64; 95% CI: 0.48 to 0.86), TLR (RR: 0.72; 95% CI: 0.59 to 0.88), ID-TLR (RR: 0.74; 95% CI: 0.59 to 0.92) and ST (RR: 0.54; 95% CI: 0.32 to 0.90). There was no difference in TVR between the everolimus-eluting and paclitaxel-eluting (RR: 0.76; 95% CI: 0.58 to 1.10); Four-year outcomes of everolimus-eluting compared to paclitaxel-eluting: the everolimus-eluting significantly reduced MACE (RR: 0.44; 95% CI: 0.18 to 0.98) and ID-TLR (RR: 0.47; 95 % CI: 0.23 to 0.97). There was no difference in MI (RR: 0.48; 95% CI: 0.16 to 1.46), TLR (RR: 0.46; 95% CI: 0.20 to 1.04) and ST ((RR: 0.34; 95% CI: 0.05 to 2.39). Five-year outcomes of everolimus-eluting stent compared to paclitaxel-eluting: There was no difference in ID-TLR (RR: 0.67; 95% CI: 0.45 to 1.02) and ST (RR: 0.71; 95% CI: 0.28 to 1.80). CONCLUSIONS: In the present meta-analysis, everolimus-eluting appeared to be safe and clinically effective in patients undergoing PCI in comparison to PES in 3-year clinical outcomes; there was similar no difference in reduction of ST between EES and PES in long-term(≥ 4 years) clinical follow-ups. Everolimus-eluting is more safety than paclitaxel-eluting in long-term clinical follow-ups, whether these effects can be applied to different patient subgroups warrants further investigation.

Symptoms of cardiovascular diseases are frequently found in patients with hypothyroidism and hyperthyroidism. However, it is unknown whether arachidonic acid metabolites, the potent mediators in cardiovascular system, are involved in cardiovascular disorders caused by hyperthyroidism and hypothyroidism. To answer this question, serum levels of arachidonic acid metabolites in human subjects with hypothyroidism, hyperthyroidism and mice with hypothyroidism or thyroid hormone treatment were determined by a mass spectrometry-based method. Over ten arachidonic acid metabolites belonging to three catalytic pathways: cyclooxygenases, lipoxygenases, and cytochrome P450, were quantified simultaneously and displayed characteristic profiles under different thyroid hormone status. The level of 20-hydroxyeicosatetraenoic acid, a cytochrome P450 metabolite, was positively correlated with thyroid hormone level and possibly contributed to the elevated blood pressured in hyperthyroidism. The increased prostanoid (PG) I2 and decreased PGE2 levels in hypothyroid patients might serve to alleviate atherosclerosis associated with dyslipidemia. The elevated level of thromboxane (TX) A2, as indicated by TXB2, in hyperthyroid patients and mice treated with thyroid hormone might bring about pulmonary hypertension frequently found in hyperthyroid patients. In conclusion, our prospective study revealed that arachidonic acid metabolites were differentially affected by thyroid hormone status. Certain metabolites may be involved in cardiovascular disorders associated with thyroid diseases.

OBJECTIVE: To investigate the safety and feasibility of laparoscopic removal of exogenous caesarean scar pregnancy (CSP). METHODS: From January 2009 to May 2011, 71 patients with CSP treated in Shengjing Hospital of China Medical University were studied retrospectively. Thirty-nine patients were treated with hysteroscopic excision of CSP, while 32 patients were treated with laparoscopic surgery. The following clinical parameters were compared, including intraoperative blood loss, quantity of postoperative uterine drainage, postoperative hospital days, the time for the mass absorption and the return of ß-hCG to normal were studied. RESULTS: Two cases in the hysteroscopic group were transformed to abdominal surgery because of introperative bloody loss, the 37 cases underwent hysteroscopic surgery successfully with the ultrasound supervision and guidance.Laparoscopic surgery were successfully completed in all 32 cases.In hysteroscopic group, the operation time, the time for the return of serum ß-hCG to normal, postoperative uterine drainage volume and the postoperative hospital stay were (44 ± 18) minutes, (27 ± 5) days, (38 ± 12) ml, (3.8 ± 0.7) days.While, in laparoscopic group, they were (100 ± 21) minutes, (17 ± 4) days, (19 ± 6) ml, (3.5 ± 0.6) days, respectively, the differences reached statistically significant (all P < 0.05). But the amount of intraoperative bleeding were was (113 ± 63) ml in hysteroscopic group and (109 ± 59) ml in laparoscopic group, the difference was not statistically significant (P > 0.05). The duration of absorption of mass were (88 ± 17) days in hysteroscopic group.In laparoscopic group, the mass were completely removed. CONCLUSIONS: Laparoscopic exicion of CSP could be suitable in treatment of exogenous CSP which offers advantages including prompt recovery, blood loss and hospital stays. This management could repair the uterine scars, reduce the reoccurring risk and conservate the fertility potential.

Purpose: To investigate the influencing factors of self-management of diabetic retinopathy (DR) by constructing a structural equation model (SEM) to analyze the relationships among self-management behavior, perceived social support, and trait coping style as well as to determine the influencing path in order to provide a theoretical reference for exploring a multipath health management model that can be used to improve the quality of life of DR patients. Patients and Methods: A total of 388 patients with DR were enrolled in this cross-sectional study conducted from January 2020 to January 2023. All subjects completed a general questionnaire and were assessed by the Self-management Scale for Patients with Diabetic Retinopathy, the Perceived Social Support Scale, and the Trait Coping Style Scale. Structural equation modeling was employed to examine the relationship between self-management and its influencing factors. The bootstrap method was used to examine the path relationships among self-management, perceived social support, and trait coping styles in DR patients. Results: A total of 346 valid questionnaires were collected in this study, with a response rate of 89% (346/388). The average score of self-management of DR patients was 69.50±18.32, and it was significantly positively correlated with perceived social support and positive coping (r=0.624, r=0.578, both P<0.01). The total effect of perceived social support on DR self-management was 1.439, with a direct effect of 1.056 and an indirect effect of 0.384. Positive coping played a mediating role in perceived social support and self-management. Conclusion: The self-management of DR was at an intermediate level. Perceived social support and trait coping styles were important influencing factors for self-management behavior in DR patients. Therefore, improving perceived social support and trait coping styles can promote the self-management behavior of DR patients, reduce their psychological burden, and improve their compliance and quality of life.
RESUMO
RATIONALE: Congenital heart disease (CHD) is the most common birth defect and an important cause of noninfectious deaths in infants and children. It has high prevalence globally, placing an enormous burden on society and families. Studies of individuals with hereditary or sporadic CHD have provided strong evidence for its genetic basis. The aim of this study was to identify causative gene variants in a Chinese family with congenital heart disease. PATIENT CONCERNS AND DIAGNOSES: Three generations of a CHD family were recruited. Proband III.9 was diagnosed with congenital heart disease at age 11 months, and the echocardiogram showed arterial ductus arteriosus, with a left-to-right shunt at the level of the arteries. Precedent III.10 was a twin of Proband III.9 who was diagnosed with congenital heart disease at age 11 months, in whom the echocardiogram revealed an arterial ductus arteriosus, an unenclosed patent ductus arteriosus, and a left to right shunt at the level of the arteries (second figure). III.8 was diagnosed with congenital heart disease at age 15, but echocardiography in this study showed no abnormalities. No cardiac abnormalities were detected in any of his parents, grandparents, or maternal grandparents. We performed whole-exome sequencing on CHD sufferers and their unexpressing family members to investigate the genetic causes of CHD in this family line. Exome sequencing identified 4 mutation sites in this family line. The variant c.3245A>G (p.His1082Arg) of the AMER1 gene was consistent with concomitant X-chromosome recessive inheritance, the variant c.238G>C (p.Val80Leu) of the KCNE1 gene was consistent with autosomal accessory inheritance, and the other 2 variants did not conform to the law of the mode of inheritance of the disease. OUTCOMES: The first identified variant, c.3245A>G (p.His1082Arg) of the AMER1 gene, with X-chromosome recessive inheritance, and the variant c.238G>C (p.Val80Leu) of the KCNE1 gene, which has been reported as autosomal dominant, may be the causative agent of CHD in this family line. These findings broaden the genetic scope of congenital heart disease and could help in the development of targeted drugs for the treatment of congenital heart disease.

BACKGROUND AND AIMS: The association of blood transfusion with an increase in medium- and short-term mortality in specific populations has been confirmed. However, the correlation between blood transfusion and long-term mortality in the general population remains unclear. This cohort study evaluated the correlation between blood transfusion and overall and cause-specific mortality in the general American adult population. METHODS: The authors utilized 10 sets of 2-year cycle data (1999-2018) from the National Health and Nutrition Examination Survey on the outcomes of adults who did and did not receive blood transfusions. Propensity score-matching (1:1) was performed based on age, sex, race, education level, marital status, poverty-income ratio, arteriosclerotic cardiovascular disease, cancer, anemia, hypertension, and diabetes status. After controlling for demographic characteristics and clinical risk factors, Cox regression analysis was performed to evaluate the correlation between blood transfusion and all-cause and cause-specific mortality. RESULTS: The study included 48,004 adult participants. The risk of all-cause mortality increased by 101 % with blood transfusion, and the risk of cardiovascular mortality increased by 165 %. After propensity score-matching, 6,116 pairs of cases were retained, and the risk of all-cause mortality increased by 84 % with blood transfusion, and the risk of cardiovascular mortality increased by 137 %. The sensitivity analysis results were robust. CONCLUSIONS: In the general American population, blood transfusion significantly impacts long-term all-cause and cardiovascular mortality and may be an unacknowledged risk factor for death. Thus, the effective management of blood transfusion in the general population may be beneficial.
