Navigating Challenges and Seizing Opportunities in China's Era of Online Health Education.

The rapid growth of internet users in China presents opportunities for advancing the "Healthy China 2030" initiative through online health education. Platforms like "Shanghai Health Cloud" and "National Health Information Platform" improve health literacy and management, enhancing overall public health. However, challenges such as the digital divide and the spread of unverified health information hinder progress. Addressing these issues requires enhancing digital infrastructure, employing advanced technologies for information validation, and setting high standards for online health services. Integrated efforts from various sectors are essential to maximize the benefits of online health education in China.

The effect of double W tension-reduced suture technique on the abdominal scars following the da Vinci robot-assisted gastrectomy for severely obese patients.

OBJECTIVE: To analyze the effect of a new type of tension-reduced suture named "double W tension-reduced suture technique" on the abdominal scars following the da Vinci robot-assisted gastrectomy for severely obese patients. METHODS: 40 abdominal incisions following the da Vinci robot-assisted gastrectomy on severely obese patients from September 1st, 2021 to March 1st, 2022 were comprised in the study. 20 incisions were closed by the conventional full-thickness surgical suture as the control group, and 20 incisions were sewn up by double W tension-reduced suture as the double W group. The scars were assessed at the 1-month follow-up visit using the Vancouver scar scale (VSS), ultrasound and patient satisfaction. Meanwhile, digital photographs of scars were taken as well. RESULTS: The VSS score was 6.80 ± 2.16 in the control group, while that of the double W group was 2.60 ± 1.89. The difference between groups was significant. Digital photographs showed that the scar color was not only light and close to the skin color, but also flat and soft in the double W group. Ultrasound showed that the fibers of subcutaneous tissue in the double W group were arranged neatly, the ultrasonic signal intensity was relatively uniform, and the tunnel was small without obvious lacunae. More patients were satisfied and very satisfied with scars in the double W group. CONCLUSION: Double W tension-reduced suture technique could significantly improve the appearance and reduce comorbidities of scars following the da Vinci robot-assisted gastrectomy for severely obese patients.

Medullary cavity application of tranexamic acid to reduce blood loss in tibial intramedullary nailing procedures-a randomized controlled trial.

PURPOSE: Studies have shown an average postoperative hidden blood loss (HBL) of 473.29 ml and an average Hb loss of 16.71 g/l after intramedullary nailing. Reducing HBL has become a primary consideration for orthopaedic surgeons. METHODS: Patients with only tibial stem fractures who visited the study clinic between December 2019 and February 2022 were randomized into two groups using a computer-generated form. Two grams of tranexamic acid (TXA) (20 ml) or 20 ml of saline was injected into the medullary cavity before implantation of the intramedullary nail. On the morning of the surgery, as well as on days one, three and five after surgery, routine blood tests and analyses of CRP and interleukin-6 were completed. The primary outcomes were total blood loss (TBL), HBL, and blood transfusion, in which the TBL and HBL were calculated according to the Gross equation and the Nadler equation. Three months after surgery, the incidence of wound complications and thrombotic events, including deep vein thrombosis and pulmonary embolism, was recorded. RESULTS: Ninety-seven patients (47 in the TXA group and 50 in the NS group) were analyzed; the TBL (252.10 ± 10.05 ml) and HBL (202.67 ± 11.86 ml) in the TXA group were significantly lower than the TBL (417.03 ± 14.60 ml) and HBL (373.85 ± 23.70 ml) in the NS group (p < 0.05). At the three month postoperative follow-up, two patients (4.25%) in the TXA group and three patients (6.00%) in the NS group developed deep vein thrombosis, with no significant difference in the incidence of thrombotic complications (p = 0.944). No postoperative deaths or wound complications occurred in either group. CONCLUSIONS: The combination of intravenous and topical TXA reduces blood loss after intramedullary nailing of tibial fractures without increasing the incidence of thrombotic events.

A population-based study on time trends of hemoglobin in primary care comparing prediagnostic colorectal cancer patients vs age- and sex-matched controls.

BACKGROUND: Some 40% of colorectal cancer (CRC) patients present with anemia. Temporal trends of gradually decreasing Hb are suggested as a supplementary diagnostic tool for CRC. We set out to explore this concept in a strictly defined population. METHODS: A laboratory database identified patients ≥40 years that had ≥1 Hb test reported from primary care, Örebro county in 2000-17. Linkage to the Swedish Colorectal Cancer Registry identified patients diagnosed with CRC. Other primary care patients served as controls (1:10), matched by age and sex. Prediagnostic Hb in cases and controls were compared and temporal trajectories of Hb modelled using a nonlinear three-parameter logistic function. RESULTS: 1,534 CRC patients and 15,333 controls were identified. The average number of reported Hb tests in primary care per year increased successively, and diagnostic delay from detection of anemia to diagnosis of CRC decreased; in 2015-17 it was median 4 (IQR 2-6) months. No association was found between last Hb and stage of right-/left-sided colon, or rectal cancer.A statistically significantly lower Hb in CRC patients was discernable 609 days (20 months) prior to diagnosis for men and 905 days (30 months) for women, both in the range of normal Hb. The frequency of Hb testing in the general population via primary care was surprisingly low, and was ≥50% annually only in octogenarians. CONCLUSION: The findings indicate a potential for Hb trends to inform the diagnostic process of CRC but whether it will translate into any clinical advantage is yet uncertain.

Comparison and trend of perioperative outcomes between robot-assisted radical prostatectomy and open radical prostatectomy: nationwide inpatient sample 2009-2014.

PURPOSE: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. MATERIALS AND METHODS: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. RESULTS: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. CONCLUSIONS: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

Impact of thiopurines on the natural history and surgical outcome of ulcerative colitis: a cohort study.

OBJECTIVE: Thiopurines are used as maintenance therapy in ulcerative colitis (UC), but whether these drugs influence the natural history of the disease is unknown. We aimed to assess the effect of thiopurines in terms of colectomy, hospital admission, progression in disease extent and anti-tumour necrosis factor (TNF) therapy within 10 years from initiation. DESIGN: Patients diagnosed with UC within the Örebro University Hospital catchment area, during 1963-2010, who initiated thiopurines (n=253) were included. To overcome the risk of confounding by indication, we compared patients who stopped treatment within 12 months because of an adverse reaction (n=76) with patients who continued therapy or discontinued due to other reasons (n=177) and assessed long-term outcomes using Cox regression with adjustment for potential confounding factors. RESULTS: The cumulative probability of colectomy within 10 years was 19.5% in tolerant patients compared with 29.0% in intolerant (adjusted HR 0.49; 95% CI 0.21 to 0.73). The probability of hospital admission was 34.0% in tolerant versus 56.2% in intolerant patients (adjusted HR 0.36; 95% CI 0.23 to 0.56). The risk for progression in disease extent was 20.4% in tolerant patients compared with 48.8% in intolerant (adjusted HR 0.47; 95% CI 0.21 to 1.06). Within 10 years, 16.1% of tolerant and 27.5% of intolerant patients received anti-TNF therapy (adjusted HR 0.49; 95% CI 0.26 to 0.92). CONCLUSION: Based on the novel approach of comparing patients tolerant and intolerant to thiopurines, we reveal that thiopurines have a profound beneficial impact of the natural history and long-term colectomy rates of UC.

Study on the Dose-Response Relationship between Magnesium and Type 2 Diabetes of Childbearing Women in the China Adult Chronic Disease and Nutrition Surveillance 2015.

Background: Magnesium (Mg) is an essential element and participates in many metabolic pathways. Many studies have found a certain negative correlation between magnesium and blood glucose parameters, but the dose-response relationship between them is still a relatively narrow research field. We aim to explore the dose-response relationship between plasma and dietary Mg and type 2 diabetes (T2DM) among childbearing women in a nationally representative sample. And we will also initially explore the threshold of dietary and plasma magnesium in the prevention of T2DM and their consistency. Methods: A total of 2912 18-44 year-old childbearing women were recruited from the China Adult Chronic Disease and Nutrition Surveillance (2015). Multivariate logistic regression was used to explore the dose-response relationship between plasma and dietary Mg and glucose parameters. The threshold effect between Mg and T2DM was explored by a restricted cubic spline regression. Results: It was found that when plasma Mg was increased by 0.041 mmol/L, the risk of T2DM, impaired fasting glucose (IFG), and HbA1c-hyperglycemia was reduced by 18%, 19%, and 18%, respectively. The possible threshold value for plasma Mg to prevent the risk of T2DM was 0.87 mmol/L. Through the quality control of the sample dietary survey data, 2469 cases were finally included for dietary analysis. And the possible threshold value for dietary Mg to prevent the risk of T2DM was 408 mg/d. Taking the recommended dietary Mg intake of 330 mg/d as the reference group, when the Mg intake reached 408 mg/d, the risk of T2DM was significantly reduced. And the average plasma Mg level of the people whose dietary intake reached 408 mg/d was 0.87 mmol/L. Conclusions: These results indicate that dietary Mg and plasma Mg have good consistency on the threshold effect of glucose parameters in women of childbearing age.

A simple way to intrude overerupted upper second molars with miniscrews.

Various methods of using skeletal anchorage for the intrusion of overerupted maxillary molars have been reported; however, it is difficult to intrude the overerupted upper second molars because of the low bone density in the region of the tuberosity. This article illustrates a new treatment method using partial fixed edgewise appliances and miniscrews to intrude the overerupted upper second molars. The miniscrews were applied to reinforce the anchorage of the upper first molar. The intrusive force was generated by the Ni-Ti wire. The clinical results showed a significant intrusion effect without root resorption or periodontal problems. This report demonstrates that the combination of partial conventional fixed appliances with miniscrews is a simple and effective treatment option to intrude overerupted upper second molars, especially in situations where miniscrews cannot be inserted directly next to the second molar.

Study on the participation of nursing staff in tobacco cessation support and related influencing factors: A survey from Chongqing, China.

INTRODUCTION: Nursing staff's assistance for smokers to quit smoking can increase the rate of quitting. The smoking cessation help can be affected by many factors. This study surveyed the use of the 5As (Asking, Advising, Assessing, Assisting, Arranging) approach to support smoking cessation by the nursing staff in Chongqing, China, and analyzed the corresponding influencing factors. METHODS: A stratified random cluster sampling method was used to select nursing staff from 8 tertiary hospitals, 5 secondary hospitals, 12 community health centers, and 35 township health centers in different geographical regions of Chongqing. A questionnaire survey was conducted among the nursing staff to investigate their participation in smoking cessation. Binary logistic regression analysis was employed to analyze the influencing factors of smoking cessation 5As behavior of the nursing staff. RESULTS: The 1669 participants were 44 males (2.6%) and 1625 females (97.4%), with an average age of 37.00 ± 10.89 years. Among the participants, 55.2% were from tertiary hospitals, 23.2% from secondary hospitals, 14.2% from township health centers, and 7.4 from community health centers. The often or always used behaviors were: Asking, 69.2%; Advising, 53.0%; Assessing, 39.5%; Assisting, 33.7%; and Arranging, 25.1%. The factors that affected all the 5As were: smoking cessation training (AOR=1.60; 95% CI: 1.22-2.11), knowledge of smoking cessation guidelines (AOR=1.75; 95% CI: 1.32-2.32) and the use of smoking cessation Apps (AOR=1.50; 95% CI: 1.09-2.06), and smokers' willingness to quit (AOR=2.20; 95% CI: 1.60-3.02). CONCLUSIONS: Smoker's motivation to quit smoking and nurses' knowledge of tobacco cessation resources affected nurses' participation in smoking control behavior. While encouraging smokers to quit smoking, clinical nursing staff should be provided with related resources to advocate smoking cessation. Guided by the Chinese Clinical Tobacco Cessation Guidelines, smoking control knowledge and skills training should be provided for nursing staff to increase their positive attitude towards smoking control, so as to promote their active participation.

Clinical practice selectively follows acute appendicitis guidelines.

INTRODUCTION: Acute appendicitis is a common surgical emergency, and the standard approach to diagnosis and management has been codified in several practice guidelines. Adherence to these guidelines provides insight into independent surgical practice patterns and institutional resource constraints as impediments to best practice. We explored data from the recent ESTES SnapAppy observational cohort study to determine guideline compliance in contemporary practice to identify opportunities to close evidence-to-practice gaps. METHODS: We undertook a preplanned analysis of the ESTES SnapAppy observational cohort study, identifying, at a patient level, congruence with, or deviation from WSES Jerusalem guidelines for the diagnosis and management of acute appendicitis and the Surviving Sepsis Campaign in our cohort. Compliance was then correlated with the incidence of postoperative complications. RESULTS: Four thousand six hundred and thirteen (4613) consecutive adult and adolescent patients with acute appendicitis were followed from date of admission (November 1, 2020, and May 28, 2021) for 90 days. Patient-level compliance with guideline elements allowed patients to be grouped into those with full compliance (all 5 elements: 13%), partial compliance (1-4 elements: 87%) or noncompliance (0 elements: 0.2%). We identified an excess postoperative complication rate in patients who received noncompliant and partially compliant care, compared with those who received fully guideline-compliant care (36% and 16%, versus 7.3%, p < 0.001). CONCLUSIONS: The observed diagnostic and treatment practices of the participating institutions displayed variability in compliance with key recommendations from existing guidelines. In general, practice was congruent with recommendations for preoperative antibiotic surgical site infection prophylaxis administration, time to surgery, and operative approach. However, there remains opportunities for improvement in the choice of diagnostic imaging modality, postoperative antibiotic stewardship to timely discontinue prophylactic antibiotics, and the implementation of ambulatory treatment pathways for uncomplicated appendicitis in the healthy young adult.

Deep learning segmentation of the tear fluid reservoir under the sclera lens in optical coherence tomography images.

The tear fluid reservoir (TFR) under the sclera lens is a unique characteristic providing optical neutralization of any aberrations from corneal irregularities. Anterior segment optical coherence tomography (AS-OCT) has become an important imaging modality for sclera lens fitting and visual rehabilitation therapy in both optometry and ophthalmology. Herein, we aimed to investigate whether deep learning can be used to segment the TFR from healthy and keratoconus eyes, with irregular corneal surfaces, in OCT images. Using AS-OCT, a dataset of 31850 images from 52 healthy and 46 keratoconus eyes, during sclera lens wear, was obtained and labeled with our previously developed algorithm of semi-automatic segmentation. A custom-improved U-shape network architecture with a full-range multi-scale feature-enhanced module (FMFE-Unet) was designed and trained. A hybrid loss function was designed to focus training on the TFR, to tackle the class imbalance problem. The experiments on our database showed an IoU, precision, specificity, and recall of 0.9426, 0.9678, 0.9965, and 0.9731, respectively. Furthermore, FMFE-Unet was found to outperform the other two state-of-the-art methods and ablation models, suggesting its strength in segmenting the TFR under the sclera lens depicted on OCT images. The application of deep learning for TFR segmentation in OCT images provides a powerful tool to assess changes in the dynamic tear film under the sclera lens, improving the efficiency and accuracy of lens fitting, and thus supporting the promotion of sclera lenses in clinical practice.

Single-agent capecitabine maintenance therapy after response to capecitabine-based combination chemotherapy in patients with metastatic breast cancer.

We performed an analysis of the efficacy of capecitabine monotherapy as maintenance treatment for metastatic breast cancer (MBC) after response to capecitabine-based chemotherapy [capecitabine plus docetaxel (XT) or vinorelbine (XN)] as a first-line or a second-line treatment. Sixty-four Chinese patients with histologically confirmed MBC received capecitabine maintenance therapy after disease stabilization or maximal response to capecitabine-based combination chemotherapy. Single-agent capecitabine was administered at a dose of 1000 mg/m(2) twice daily for 14 days, followed by a 7-day rest period, every 3 weeks. The median time to progression, the primary endpoint of the study, was 4.4 months (95% confidence interval, 3.4-5.4 months). Fifty-nine patients were evaluable for response. Capecitabine maintenance therapy produced an objective response rate of 5.1% (95% confidence interval, 3.9-6.3%). The incidence of grade 3/4 leukopenia (3.1%) and neutropenia (4.7%) was significantly lower (P<0.001) with capecitabine monotherapy than with combination chemotherapy (46.9 and 54.7%, respectively). Conversely, the incidence of grade 3 hand-foot syndrome was higher with capecitabine maintenance therapy than with combination therapy (14.1 vs. 0%, respectively; P=0.003). Capecitabine monotherapy is an effective maintenance treatment after response to capecitabine-based combination chemotherapy in MBC with a favorable safety profile.

Quality of Life After Percutaneous Coronary Intervention in No-Touch Saphenous Vein Grafts is Significantly Better Than in Conventional Vein Grafts.

OBJECTIVE: To compare health-related quality of life (HRQoL) of patients primarily treated with a no-touch saphenous vein graft with that of patients who received a conventional graft. METHODS: The study included all individuals treated with a percutaneous coronary intervention (PCI) on a saphenous vein graft (SVG) between January 2006 and June 2020. The RAND-36 health survey was used to assess HRQoL. The Mann-Whitney U test was used to test differences in HRQoL between the two groups. Effect size was estimated via Cohen's d. The average treatment effect between the groups was tested by propensity score matching (PSM). RESULTS: Of the 346 patients treated with a PCI in a stenosed or occluded SVG, 165 responded to RAND-36 (no-touch: n=48; conventional: n=117). Patients with a no-touch graft reported better mean values on seven of the eight health survey domains. Statistically significant differences were observed for four of the domains, all in favour of the no-touch group. The effect size estimates indicated a small difference for five domains, with the highest values (>0.40) seen for the general health and energy/fatigue domains. PSM confirmed a statistically significant difference for the physical functioning and general health domains. CONCLUSION: At a mean follow-up of 5.4 years, patients who received a PCI in no-touch vein grafts showed significantly better HRQoL than those who received a PCI in conventional vein grafts.

Surgical management of displaced femoral neck fractures in patients with dementia: a comparison in mortality between hemiarthroplasty and pins/screws.

INTRODUCTION: Dementia is common in patients with hip fractures and is strongly associated with increased postoperative mortality. The choice of surgical intervention for displaced femoral neck fractures (dFNF) in patients with dementia has been a matter of debate. This study aims to investigate how short- and long-term mortality differs between those who have been operated with hemiarthroplasty or pins/screws. METHODS: All patients with dementia and dFNF, i.e., Garden III and IV, who underwent primary emergency hip fracture surgery, with either hemiarthroplasty or pins/screws, in Sweden between Jan 1, 2008 and Dec 31, 2017 were eligible for inclusion in the current study. Patients were divided into two groups based on the surgical intervention: hemiarthroplasty and pins/screws. The primary outcome of interest was 30-day postoperative mortality, and the secondary outcome was 1-year postoperative mortality. Poisson and Cox regression analyses were performed both before and after propensity score matching. RESULTS: A total of 9394 cases met the inclusion criteria; 84% received hemiarthroplasty and 16% received pins/screws. In the unmatched analysis, the adjusted incidence rate ratio (IRR) for 30-day postoperative mortality was not affected by the chosen surgical method (adj. IRR 0.96, CI 95% 0.83-1.12, p = 0.629). After propensity score matching, similar results were observed with no difference in 30-day postoperative mortality (adj. IRR 0.89, CI 95% 0.74-1.09, p = 0.286). There was a statistically significant decrease in the risk of 1-year postoperative mortality in the hemiarthroplasty group compared to the pins/screws group, both before and after propensity score matching. CONCLUSION: This study could not demonstrate any difference in 30-day mortality in patients with dementia and dFNFs when comparing hemiarthroplasty with pins/screws. Patients that received hemiarthroplasties did, however, have a lower risk of 1-year postoperative mortality.

Determination of clinically acceptable cut-offs for hemolysis index: An application of bootstrap method using real-world data.

OBJECTIVES: To assess the impact of hemolysis on laboratory results under local conditions and to verify the hemolysis index cut-off for potassium using real-world data. METHODS: The statistical bootstrapping method was performed on 54,125 samples collected at the University Hospital of Örebro (USÖ). The results were compared to a method based on stratification of samples according to hemolysis level, and on paired difference testing. RESULTS: Setting the acceptable allowable limit of error to 10%, the three assessed strategies yielded comparable results with respect to the impact of haemolytic interference on test results for potassium. The suggested cut-offs were 111 mg Hb/dL for the bootstrapping method, between 125-150 mg Hb/dL for the method based on stratification, and around 150 mg/dL for the paired difference testing strategy. The impact of hemolysis on potassium measurement is likely different between primary care patients and inpatients. CONCLUSIONS: Using the effect of hemolysis on potassium measurement as a model, a novel approach towards finding clinically acceptable limits for analytical interference is presented, that relies on the bootstrapping method and on actual patient data from routine laboratory operation, hence incorporating local population characteristics, equipment and instrumental settings.

Outcome of Humeral Shaft Fracture Treated with Intramedullary Nail and Plate Fixation.

OBJECTIVE: To compare the results of the intramedullary nail (IMN) and compression plate fixation performed for humeral shaft fracture as to determine a better option out of the two. STUDY DESIGN: Comparative study. PLACE AND DURATION OF STUDY: First Affiliated Hospital of Jinzhou Medical University, Liaoning, PR China, from October 2016 to January 2019. METHODOLOGY: Patients treated with IMN (n=26) or plate fixation (n=30) for humeral shaft fracture were included in this study. Assessment was done in terms of perioperative parameters, complications, union time, and functional outcomes. Functional outcome were compared between the two groups at each follow-up (6 weeks, 3, 6, and 12 months) and between the subsequent follow-ups in both groups using the repeated measures ANOVA. RESULTS: Intraoperative blood loss, operative time, hospital stay, and union time were significantly lower in the IMN group. There was no significant difference in the functional outcomes when it was compared between the two groups at each follow-up. However, when it was compared between subsequent follow-ups, a significant improvement was observed in both groups. Increase incidence of individual complication and reoperation were established in the plating group, but without a significant difference. Yet, the overall complications rate was significantly higher in the plating group. CONCLUSION: IMN fixation led to a significant decrease in intraoperative blood loss, shorter operating time, hospital stay, union time, and a lower rate of overall complications. Thus, IMN may be a better choice of internal fixation as it also accelerates the patients' recovery, and increases their satisfaction.

Efficacy of Banxia Xiexin decoction for chronic atrophic gastritis: A systematic review and meta-analysis.

BACKGROUND: Banxia Xiexin decoction (BXD), a classical formula of traditional Chinese medicine (TCM), has been wildly used for chronic atrophic gastritis (CAG) patients with the cold-heat complex syndrome in China, and achieved satisfied effects. However, the clinical effects of it remains unclear. PURPOSE: The purpose of this article is to evaluate the clinical efficacy and safety of BXD for CAG treatment. METHODS: We searched seven electronic databases including Ovid, Embase, PubMed, Cochrane Library, Wan-fang database, VIP (Chinese Scientific Journals Database) and CNKI (China National Knowledge Infrastructure) from their inception to September 21, 2020. We used Jadad scale and Cochrane Collaboration's risk of bias tool to make evaluation of methodological quality. Revman 5.3 statistical software was used for statistical processing to evaluate the clinical efficacy and safety of BXD. RESULTS: 26 randomized controlled trials (RCTs) totaling 1985 patients were identified for analysis. Meta-analysis showed that BXD treatment was more effective (RR 1.29; 95%CI 1.24, 1.35; P<0.00001) and safe (MD 0.33; 95%CI 0.18, 0.58; P = 0.0002) than Chinese patent medicine + western medicine. Furthermore, BXD had improvement on symptoms scores such as stomach distending pain, and belching. Besides, BXD was more effective in inhibiting Helicobacter Pylori (HP), improving HP-related inflammation, and relieving the degree of glandular atrophy, intestinal metaplasia (IM), and dysplasia of gastric mucosa (GM). CONCLUSIONS: The meta-analysis showed that BXD was more effective and safer for CAG patients than the control group. However, due to limitations of methodological quality and small sample size of the included studies, further standardized research of rigorous design should be needed.

Public Transportation Environment and Medical Choice for Chronic Disease: A Case Study of Gaoyou, China.

Current research on the built environment and medical choice focuses mainly on the construction and optimization of medical service systems from the perspective of supply. There is a lack of in-depth research on medical choice from the perspective of patient demand. Based on the medical choice behaviour of patients with chronic diseases, this article identifies the spatial distribution and heterogeneity characteristics of medical choice and evaluates the balance between medical supply and demand in each block. On this basis, we explored the mechanism of patient preferences for different levels of medical facilities by considering the patient's socioeconomic background, medical resource evaluation, and other built environment features of the neighbourhood by referring to patient questionnaires. In addition to socioeconomic characteristics, the results show that public transportation convenience, medical accessibility, and medical institution conditions also have significant influences on patient preferences, and the impact on low-income patients is more remarkable. The conclusions of the study provide a reference for the promotion and optimization of the functions of urban medical resources and the guidance of relevant public health policies.

[Screening of pyrene degradation bacteria strain from the Kochia scoparia roots and its potential for promoting growth]. / ç„¦åŒ–åŽ‚åœ°è‚¤æ ¹å† è§£èŠ˜ç»†èŒçš„ç­›é€‰åŠä¿ƒç”Ÿæ½œåŠ›.

The endophytic bacteria were isolated from the roots of polycyclic aromatic hydrocarbon (PAHs)-tolerant plant. We investigated their ability of PAHs degradation and plant growth promo-ting, with the aim to provide theoretical support for bacterial-plant cooperative soil remediation. Kochia scoparia living in coking plant area were selected for strains isolation. Eight endophytic bacteria strains, which used pyrene and 1-aminocyclopropane-1-carboxylic acid (ACC) as sole carbon and nitrogen source, were isolated from the roots of K. scoparia. Three endophytic bacteria, KSE4, KSE7 and KSE8, displayed high degradation efficiency in pyrene degradation experiment. They were identified as Bacillus sp., Pseudomonas sp., and Sphingobacterium sp., respectively. The abili-ties of those three strains to produce ACC deaminase and their effects on seed germination of K. scoparia were examined under pyrene stress through liquid culture tests. The results showed that the activity of ACC deaminase decreased with increasing pyrene concentration (0-15 mg·L-1). KSE7 had the strongest promotion effect. When pyrene concentration reached to 15 mg·L-1, the germination rate and bud length of K. scoparia increased by 44.8% and 61.1%, respectively. Our results indicated that KSE7 is a promising bacterial strain for soil remediation in coking plant area.
