Objective To study the compliance and influencing factors of inhalation therapy in patients with stable chronic obstructive pulmonary disease (COPD),and carry out patient education and management accordingly. Methods COPD patients were selected from respiratory clinic of Luodian Hospital of Baoshan District of Shanghai from June to December in 2021. Compliance and inhalation techniques were assessed with the Morisky Medication Adherence Scale and the ten-step inhalation technique, and the factors influencing compliance were analyzed. Results A total of 58 outpatients with COPD were included, in which 25 cases (43.1%) with moderate or above compliance. Univariate analysis showed that the patients with course of disease ≥5 years, COPD assessment test(CAT)≥10 points, used 2 inhalation devices and inhalation technique score ≥8 points had better compliance when compared with other patients (P<0.05). Conclusion Patient education and management should be carried out actively. The patients with course of disease<5 years, CAT<10 points should be highly concerned. The inhalation devices should be chosen according to the patients' condition. Training on the use of devices should be strengthened and regularly follow-up evaluation should be carried out.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Adjuvant chemoradiotherapy,molecular targeted therapy,and immunotherapy are frequently employed to extend the survival of patients with advanced gastric cancer(GC).However,most of these treatments have toxic side effects,drug resistance,and limited improvements in survival and quality of life.Therefore,it is crucial to discover and develop new medications targeting GC that are highly effective and have minimal toxicity.In previous studies,the total terpene extract from the stem of Celastrus orbiculatus demonstrated anti-GC activity;however,the specific mechanism was unclear.Our research utilising co-immunoprecipitation-mass spectrometry(Co-IP-MS),polypyrimidine tract binding protein 1(ptbp1)clustered regularly interspaced short palindromic repeat-associated protein 9(Cas9)-knockout(KO)mouse model,tissue microarray,and functional experiments suggests that alpha actinin-4(ACTN4)could be a significant biomarker of GC.PTBP1 influences actin cytoskeleton restructuring in GC cells by interacting with ACTN4.Celastrus orbiculatus stem extract(COE)may directly target ACTN4 and affect the interaction between PTBP1 and ACTN4,thereby exerting anti-GC effects.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

ObjectiveTo investigate the short-term efficacy of orthopedic elastic bandages on gait symmetry and walking ability in children with spastic hemiplegic cerebral palsy. MethodsFrom June, 2020 to June, 2023, 31 children with spastic hemiplegic cerebral palsy from Beijing Bo'ai Hospital were randomly divided into control group (n = 15) and experimental group (n = 16). Both groups received routine rehabilitation, while the control group received routine walking training, and the experimental group wore an orthopedic elastic bandage for walking training, for four weeks. The indexes of gait symmetry of foot deviation angle ratio (affected/healthy), step length ratio (affected/healthy), gait line ratio (affected/healthy) and standing stage ratio (affected percentage/healthy percentage) were calculated before and after training, and they were measured step width and the optional and maximum walking speed of 10-meter walk test (10MWT). ResultsOne case dropped off in the experimental group. After training, the foot deviation ratio, step length ratio, gait line ratio, and standing stage ratio improved in both groups (|t| > 2.434, P < 0.05), and they were better in the experimental group than in the control group (|t| > 2.230, P < 0.05); while the optional and maximum walking speed of 10MWT improved in both groups (|t| > 9.186, P < 0.001), and they were better in the experimental group than in the control group (|t| > 2.278, P < 0.05). ConclusionWearing orthopedic elastic bandages during rehabilitation can promote the gait symmetry and walking ability of children with spastic hemiplegic cerebral palsy.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

Methods: Data of hepatitis A and hepatitis E reported in Jiaxing City from 2005 to 2021 were collected from the Chinese Disease Prevention and Control Information System. The temporal, spatial and population distribution of hepatitis A and hepatitis E were analyzed using a descriptive epidemiological method, and the trends in incidence of hepatitis A and hepatitis E were evaluated using annual percent change (APC). Results: Totally 1 830 hepatitis A cases were reported in Jiaxing City from 2005 to 2021, with an annual average incidence of 2.44/105, and 2 deaths were reported, with a fatality rate of 0.11%. The incidence of hepatitis A appeared a tendency towards a decline from 2005 to 2012 (APC=-37.807%, P<0.05) and was relatively stable from 2012 to 2021 (APC=-1.277%, P>0.05), and the incidence peaked from July to September, with a monthly average incidence of 0.30/105. Higher annual average incidence of hepatitis A was seen in urban areas than in rural areas (3.91/105 vs. 1.92/105; P<0.05), among people at ages of 30 to 39 years (4.19/105), and among men than among women (3.00/105 vs. 1.93/105; P<0.05). Farmers were the predominant occupation (759 cases, 41.31%). Totally 2 176 hepatitis E cases were reported in Jiaxing City from 2005 to 2021, with an annual average incidence of 2.91/105, and 7 deaths were reported, with a fatality rate of 0.32%. The incidence of hepatitis E was relatively stable from 2005 to 2011 (APC=3.421%, P>0.05) and appeared a tendency towards a decline from 2011 to 2021 (APC=-4.294%, P<0.05), and the incidence peaked from January to March, with a monthly average incidence of 0.38/105. Higher annual average incidence of hepatitis E was seen in urban areas than in rural areas (3.50/105 vs. 2.70/105; P<0.05), among people at ages of 70 to 79 years (6.20/105), and among men than among women (3.74/105 vs. 2.05/105; P<0.05). Farmers were the predominant occupation (1 079 cases, 49.59%). Conclusions The incidence of hepatitis A and hepatitis E appeared a tendency towards a decline in Jiaxing City from 2005 to 2021. The incidence of hepatitis A was high in summer, and cases were mainly males, young and middle-aged people and farmers. The incidence of hepatitis E was high in winter, and cases were mainly males, elderly people and farmers.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Objective:To analyze the risk factors for keratoconus through a systematic review of secondary literature.Methods:Analytical studies from Cochrane Library, PubMed, Embase database, CNKI, Wanfang Periodicals Database, VIP Chinese Science and Technology Journal Database published from January 2000 to May 2021 were searched, most of which were about the keratoconus occurrence and progression and the valid data were extracted.The case-control and the cohort studies were evaluated according to the Newcastle-Ottawa Scale.The categorical variables for combined effect size were odds ratio( OR) and 95% confidence interval ( CI). The heterogeneity was evaluated via the Q test and I2 test.The fixed-effect model was adopted when P>0.1 or I2≤50%, while the random effect model was adopted when I2>50%.The sources of heterogeneity in included evaluation indexes were analyzed through subgroup and sensitivity analysis.The publication bias was evaluated by Egger tests, Harbord tests, Peters tests and funnel plots. Results:A total of 21 papers with 30 124 keratoconus cases and 59 012 control cases enrolled, including 18 case-control studies and 3 cohort studies, whose data were from 10 countries, were included.The NOS scores of the studies were not less than 7 points.The Meta-analysis results indicated that family history ( OR: 8.68, 95% CI: 6.30-11.97), eye rubbing ( OR: 4.62, 95% CI: 3.75-5.70), allergy ( OR: 2.34, 95% CI: 1.73-3.16), obstructive sleep apnea ( OR: 1.53, 95% CI: 1.12-2.10) and Down syndrome ( OR: 7.09, 95% CI: 4.19-11.99) were the risk factors for keratoconus, and mitral valve prolapse ( P>0.05) was not a risk factor for keratoconus, and diabetes ( OR: 0.63, 95% CI: 0.50-0.79) was a protective factor for keratoconus.The subgroup analysis results indicated that the heterogeneity in allergy was partially due to the specific disease classification, and the heterogeneity in diabetes and obstructive sleep apnea was totally owing to the source of the cases.The sensitivity study showed that the results were robust after changing the analysis model.There was no bias in the included studies. Conclusions:Family history, eye rubbing, allergy, obstructive sleep apnea and Down syndrome are risk factors for keratoconus, and diabetes is a protective factor for keratoconus.
