Objective:To analyze and evaluate the application effect of magnetic navigation-guided nasojejunal tube placement in critically ill patients by literature retrieval.Methods:The Chinese databases of CNKI,Wanfang,VIP and Chinese Biomedical Literature Service System were searched,as well as the literature on randomized controlled trials of magneto-guided nasojejunal tube placement in critically ill patients in foreign language databases of PubMed,CINAHL,Cochrane Library,Web of Science,and Embase,the search period was from January 2000 to September 2023.The literature were screened according to the inclusion and exclusion criteria,and the quality of the literature was evaluated.RevMan 5.4.1 software was used to conduct a meta-analysis of the four outcomes in the literature:success rate of placement,time required for successful placement,time to recovery of vital signs,and patient satisfaction.Results:A total of 7 randomized controlled trials of 7 studies were included,including 4 Chinese studies and 3 English studies,involving 682 patients.The success rate of magnetic navigation-guided nasojejunal tube placement was higher than that of bedside blind nasojejunal tube placement,the difference was statistically significant[OR=4.78,95%CI(2.16～10.58),P<0.0001].The time required for magnetic navigation guided nasojejunal tube placement was less than that of the bedside blind nasojejunal tube placemen,the difference was statistically significant[MD=-12.91,95%CI(-22.93～-2.90,P<0.00001].The time required for recovery of vital signs in patients with magnetic navigation guided nasojejunal tube placement was less than that of the bedside blind nasojejunal tube placemen,the difference was statistically significant[MD=-9.11,95%CI(-12.09～-6.13,P<0.00001].The satisfaction of patients with the magnetic navigation-guided nasojejunal tube placement was higher than that of patients with the bedside blind nasojejunal tube placement,the difference was statistically significant[OR=11.61,95%CI(3.96～34.01),P<0.00001].Conclusion:Compared with bedside blind nasojejunal tube placement,magnetic navigation-guided nasojejunal tube placement can significantly improve the success rate of nasojejunal tube placement in critically ill patients,reduce the time required for successful nasojejunal tube placement,reduce the recovery time of patients'vital signs,and improve patient satisfaction.

Objective To explore the changes of the thickness of myometrium(MT),apparent diffusion coefficient value of myometrium(ADCM),thickness of junctional zone(JZT)and apparent diffusion coefficient value of junctional zone(ADCJz)in patients with endometrial fibrosis.Methods A total of 59 patients with endometrial fibrosis and 34 healthy women(volunteer)of childbearing age were prospectively included.The JZT,ADCJz,MT and ADCM were measured.Independent samples t-test was used to compare the differences in JZT,ADCJZ,MT,and ADCM between the two groups.A combined prediction model was established using binary logistic regression analysis(combining mean JZT,mean ADCJZ,and mean MT).The efficiency of each parameter's mean value and the combined prediction model in diagnosing endometrial fibrosis was evaluated using the receiver operating characteristic(ROC)curve.Results JZT(anterior wall,posterior wall,fundus and mean;P=0.007,0.035,0.001 and＜0.001,respectively),ADCJZ(anterior wall,posterior wall,fundus and mean;all P＜0.001)and MT(anterior wall,posterior wall and mean;P=0.003,＜0.001 and 0.003,respectively)were significantly larger in patients with endometrial fibrosis compared to volunteer.Mean ADCJZ[area under the curve(AUC)=0.872]and the combined prediction model(AUC=0.953)had high value for diagnosing endometrial fibrosis.Conclusion MRI can be used for noninvasively assessing the changes of myometrium and JZ in patients with endometrial fibrosis.

Malocclusion,identified by the World Health Organization(WHO)as one of three major oral diseases,profoundly impacts the dental-maxillofacial functions,facial esthetics,and long-term development of～260 million children in China.Beyond its physical manifestations,malocclusion also significantly influences the psycho-social well-being of these children.Timely intervention in malocclusion can foster an environment conducive to dental-maxillofacial development and substantially decrease the incidence of malocclusion or reduce the severity and complexity of malocclusion in the permanent dentition,by mitigating the negative impact of abnormal environmental influences on the growth.Early orthodontic treatment encompasses accurate identification and treatment of dental and maxillofacial morphological and functional abnormalities during various stages of dental-maxillofacial development,ranging from fetal stages to the early permanent dentition phase.From an economic and societal standpoint,the urgency for effective early orthodontic treatments for malocclusions in childhood cannot be overstated,underlining its profound practical and social importance.This consensus paper discusses the characteristics and the detrimental effects of malocclusion in children,emphasizing critical need for early treatment.It elaborates on corresponding core principles and fundamental approaches in early orthodontics,proposing comprehensive guidance for preventive and interceptive orthodontic treatment,serving as a reference for clinicians engaged in early orthodontic treatment.

Objective To investigate human papillomavirus(HPV)infection in Jiading District of Shang-hai,and to explore the relationship between different HPV subtypes and cervical lesions.Methods A retro-spective analysis was conducted for HPV subtype results and pathological results during the same period of time from 19 030 patients who visited Maternity and Children Health Care Hospital of Jiading District from March 13th,2023 to March 31,2024,and underwent the HPV subtype detection.The relationship between HPV infection and age and cervical lesions were analyzed.Results Out of 19 030 samples,3 506 were HPV positive,and the infection rate was 18.42%.There were 2 185 cases of single infection and 1 321 cases of mul-tiple infection.The HPV infection rate in each age group were as below:the infection rates were 30.34%in≤20-year-old group,18.46%in 20-30 year-old group,16.46%in>30-40 year-old group,14.83%in>40-50 year-old group,21.29%in>50-60 year-old group and 32.74%in>60 year-old group,and there was a statistically significant difference in HPV infection rates among different age groups(P<0.001).The top 5 subtypes were type 52(21.50%),53(10.84%),58(10.02%),33(8.33%)and 59(6.85%).The proportions of the who progressed to higher-level cervical lesions in individuals with HPV subtypes of the top 5 infection rates,as well as those with HPV16 and 18 positive,were significantly higher than that in HPV negative indi-viduals,among which the individuals with HPV16,18,58,and 33 were more likely to progress to severe cervi-cal lesions[atypical squamous cells:cannot exclude high-grade squamous intraepithelial lesion(ASC-H)+low-grade squamous intraepithelial lesion(LSIL)+high-grade squamous intraepithelial lesion(HSIL)+squamous cell carcinoma(SCC)](P<0.05).Compared to HPV 52 positive individuals with the highest infection rate,HPV 16,18,58,and 33 positive individuals were more likely to progress to higher-level cervical lesions(P<0.05).Conclusion HPV infection rates in≤20 year-old group and>60 year-old group are relatively high in Jiading District of Shanghai.The risk of progression to cervical lesions varies among different HPV subtypes.In addition to HPV 16 and 18,HPV 58 and HPV 33 are also closely related to higher levels of cervical lesions and should be given sufficient attention.

Objective:To evaluate the relationship among future self-continuity,family support and meaning in life in college students.Methods:A total of 912 college students(448 males and 464 females)were selected and assessed with the Future Self-Continuity Questionnaire(FSCQ),Family Support Scale(PSS-Fa)and Meaning in Life Questionnaire(MLQ).Results:The average score of FSCQ was(3.3±1.1),and those who were female,25 years old,senior,nonlocal census register,only child had lower FSCQ scores(P＜0.001).Regression analysis results showed that the scores of PSS-Fa and the MLQ scores of search for life meaning and presence for life mean-ing were positively correlated with the FSCQ scores(β=0.80,0.69,0.74).Conclusion:The study shows that the future self-continuity is at a medium level and improving family support and meaning in life may help to enhance their future self-continuity in college students.

Objective:To investigate the diagnostic value of nucleic acid matrix-assisted laser desorption ionization-time of flight mass spectrometry（MALDI-TOF MS）in sputum smear-negative patients with nontuberculous Mycobacterial（NTM）pulmonary disease.Methods:Clinical data of 123 patients suspected of NTM pulmonary disease admitted in Public Health Clinical Center Affiliated to Shandong University between July 2022 and November 2023 were retrospectively analyzed. Bronchoalveolar lavage fluid（BALF）specimens were collected for MALDI-TOF MS assay and MGIT 960 culture. The diagnostic efficacy of MALDI-TOF MS for NTM pulmonary disease in patients with negative sputum smears for acid-fast bacilli was evaluated with receiver operating characteristic（ROC）curve. Statistical analysis was performed using SPSS 26.0 software and MedCalc statistical software.Results:Diagnosis of NTM pulmonary disease was finally confirmed in 66 out of the 123 suspected patients. It took 8 to 24 h for MALDI-TOF MS to identify NTM species and resistance. By MALDI-TOF MS，72 NTM strains were identified，with the Mycobacterium avium complex being the most prevalent（34 strains，47.22%），followed by the Mycobacterium abscessus complex（13 strains，18.06%）；resistance to macrolides was detected in 6 cases，while no resistance to aminoglycosides was found. It took 9 to 45 days for BALF MGIT 960 culture to identify NTM，and took 7 to 15 days for NTM typing and drug sensitivity testing. By BALF MGIT 960 culture，28 NTM strains were identified；and 1 case was found to be resistant to macrolides. Using confirmed diagnosis as the gold standard，MALDI-TOF MS demonstrated higher sensitivity，negative predictive value，and agreement rate compared to MGIT 960 culture（84.85% vs. 42.42%，81.13% vs. 56.32%，80.49% vs. 62.60%， χ2=25.667，8.998，9.664， P<0.05 or <0.01）. The area under ROC curve（AUC）for MALDI-TOF MS was significantly higher than that of MGIT 960 culture（0.801 vs. 0.642， Z=3.300， P=0.001）. Conclusion:Compared to MGIT 960 culture，MALDI-TOF MS exhibits superior diagnostic efficiency in detecting NTM pulmonary disease in patients with acid-fast bacilli smear-negative sputum，with advantage of rapidly identifying NTM species and resistance.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.
