AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.

Objective:Explore the expression pattern of transcription factor activator protein 2C (TFAP2C) and identify the roles of Tfap2c during tooth development.Methods:Real-time fluorescence quantitative PCR (RT-qPCR) was used to analyze the relative expression level of Tfap2c in various organs of embryonic day(E)14.5 mouse embryos and mouse molar germs at E12.5-E18.5 and postnatal day (P)0-P7. The expression position of Tfap2c in mouse molar germs was demonstrated by frozen section immunofluorescence staining. Cultured mandibular molar germs were transfected with control small interfering RNA (siRNA) or Tfap2c siRNA to evaluate the effect of Tfap2c on tooth molar germs development, and RT-qPCR was used to detect the relative expression level of genes related to odontoblast expression. Dental mesenchymal cells were isolated from E14.5 molar germs and transfected with control siRNA or Tfap2c siRNA, cell counting kit 8 (CCK-8) and scratch healing test were applied to detect dental mesenchymal cell viability and migration.Results:Tfap2c was highly expressed in the early development period of mouse molar germs. Tfap2c was expressed in the epithelial and mesenchymal tissues of E13.5 mouse molar germs and there was no significant difference of relative expression of Tfap2c between them ( t=1.06, P=0.472). Tfap2c was expressed in mesenchymal tissues of E14.5 mouse molar germs and the relative expression of Tfap2c in mesenchymal tissues was significantly higher than epithelial tissues ( t=37.29, P<0.0001). For molar germs transfected with Tfap2c siRNA, the relative height of cusps (0.708±0.171) and the ratio of cusp height and crown height (0.321±0.068) was significantly lower than control group (1.000±0.287 and 0.483±0.166) ( t=2.79, P=0.012; t=2.85, P=0.015). But there was no significant difference in relative height (1.078±0.206, 0.993±0.254, t=0.83, P=0.419)and relative width (1.000±0.116, 0.999±0.122, t=0.01, P=0.992) of crowns between two groups. The relative expression level of genes related to odontoblast expression was decreased (Dspp: t=15.33, P<0.001; Dmp1: t=13.81, P<0.001). Tfap2c siRNA hinders cell migration in dental mesenchymal cells ( t=29.86, P=0.001), but there was no significant difference in CCK-8 absorbance value between two groups. The relative expression level of genes related to odontoblast expression was also decreased in dental mesenchymal cells transfected with Tfap2c siRNA (Dspp: t=3.86, P=0.031; Dmp1; t=4.36, P=0.022). Conclusions:Tfap2c highly expressed in the early morphogenesis period of mouse molar germs, mainly in mesenchymal tissues. Tfap2c affected the cusps formation of mouse molar germs and migration of dental mesenchymal cells.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective:To assess the efficacy of modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging for irreparable massive posterosuperior rotator cuff tears.Methods:A retrospective analysis was conducted on 59 patients (11 males and 48 females; mean age 66.70±6.10 years, range 55-79 years) treated between June 2019 and November 2022 for posterior superior irreparable massive rotator cuff tears. The treatment involved total arthroscopic oblique muscle transposition combined with partial rotator cuff repair. Shoulder mobility was measured in active supination, forward flexion, posterior external rotation, and abduction external rotation before surgery and at the final follow-up. The Constant-Murley shoulder function score, visual analogue scale (VAS) for pain, and American Shoulder and Elbow Surgeons (ASES) scores were assessed preoperatively, at 3 months, 6 months postoperatively, and at the final follow-up. MR examinations were conducted preoperatively and at 3, 6, and 12 months postoperatively to evaluate rotator cuff healing and retear rates.Results:All surgeries were successfully completed using an average of 3.2±0.5 anchor nails (range 3-5) per case. The mean follow-up period was 15.9±5.7 months (range 12-37 months). Significant improvements in shoulder mobility were observed postoperatively compared to preoperative measurements. The mean body external rotation angle increased from 12.0°±19.4° preoperatively to 35.3°±19.6° at the final follow-up ( P<0.05), and the mean abduction external rotation angle increased from 33.4°±22.4° to 43.4°±23.1° ( P<0.05). The mean preoperative abduction angle improved from 121.7°±47.9° to 136.4°±40.6° ( P<0.05), and the mean forward flexion supination angle improved from 117.6°±45.8° to 139.5°±33.7° ( P<0.05). Postoperative VAS scores significantly improved from 4.8±1.8 preoperatively to 0.3±0.8 at the final follow-up ( F=104.868, P<0.001). The ASES scores improved from 42.0±14.9 preoperatively to 71.7±14.6 at the final follow-up ( F=47.287, P<0.001). The Constant-Murley scores increased from 54.3±17.1 preoperatively to 76.4±13.0 at the final follow-up ( F=44.082, P<0.001). Postoperative complications included 2 complete tears and 7 partial tears (re-tear rate 15.3%). No serious complications such as shoulder joint infection, joint stiffness, or vascular nerve injury were observed. One patient developed a localized subcutaneous hematoma at the tendon extraction site, and another developed deep vein thrombosis of the lower extremity, which improved with symptomatic anticoagulation. Conclusion:Modified arthroscopic lower trapezius transfer with autologous hamstring tendon bridging effectively reduces shoulder pain, improves shoulder joint activity and function scores, and is associated with a low rate of surgical complications for patients with irreparable massive posterosuperior rotator cuff tears.

There were 24 cases on the left side and 10 cases on the right side. Causes of injury: 23 cases of car accident, 7 cases of fall, 4 cases of falling from height. Rockwood classification: Type III 17 cases, type IV 9 cases, type V 8 cases. The visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, and joint range of motion were used to evaluate shoulder pain and functional improvement.Results:All patients successfully completed the operation and were followed up for an average of 16.6±2.8 months (range, 12-24 months). Postoperative VAS scores were significantly lower compared to preoperative scores ( F=199.408, P<0.001), with the final follow-up VAS score being 1.32±0.47, significantly lower than the preoperative score of 4.71±1.19 ( P<0.001). Postoperative ASES scores were significantly higher compared to preoperative scores ( F=335.838, P<0.001), with the final follow-up ASES score being 88.85±6.41, significantly higher than the preoperative score of 34.76±5.79 ( P<0.001). The Constant-Murley scores of 3 months, 6 months after operation and the last follow-up were 77.79±5.34, 87.40±5.19 and 88.17±4.40, respectively, which were higher than that before operation 37.41±6.52, and the difference was statistically significant ( P<0.05). At the final follow-up, shoulder flexion, adduction, and abduction were 172.9°±6.4°, 59.2°±6.2°, and 59.3°±5.9°, respectively. The coracoclavicular distance was 1.76±0.42 mm, 0.84±0.19 mm, and 0.87±0.18 mm before operation, 3 months after operation, and at the last follow-up, respectively, and the difference was statistically significant ( F=101.160, P<0.001). Whereas, 3 months postoperative and the final follow-up were smaller than the preoperative ones, and the difference was statistically significant ( P<0.05). All incisions healed in one stage, and there was no vascular or nerve injury, internal fixation infection, coracoid process or clavicle bone tunnel fracture, or internal fixation loosening or breakage. Conclusion:Arthroscopic double-bundle Endobutton fixation with thin bone channel for the treatment of Rockwood type III-V acromioclavicular joint dislocation can improve shoulder function and reduce pain, with high surgical safety.

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

OBJECTIVES:
During the coronavirus disease 2019 (COVID-19) pandemic, a growing prevalence of racial and ethnic discrimination occurred when many Americans struggled to maintain healthy lifestyles. This study investigated the associations of racial and ethnic discrimination with changes in exercise and screen time during the pandemic in the United States.
METHODS:
We included 2,613 adults who self-identified as non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, or Hispanic from the Health, Ethnicity, and Pandemic study, a cross-sectional survey conducted among a nationally representative sample of United States adults between October and November 2020. We assessed self-reported racial and ethnic discrimination by measuring COVID-19-related racial and ethnic bias and examined its associations with changes in exercise and screen time using multivariable logistic regression models. We analyzed data between September 2021 and March 2022.
RESULTS:
COVID-19-related racial and ethnic bias was associated with decreased exercise time among non-Hispanic Asian (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.13 to 1.89) and Hispanic people (OR, 1.91; 95% CI, 1.32 to 2.77), and with increased screen time among non-Hispanic Black people (OR, 1.94; 95% CI, 1.33 to 2.85), adjusting for age, sex, education, marital status, annual household income, insurance, and employment status.
CONCLUSIONS
Racial and ethnic discrimination may have adversely influenced exercise and screen time changes among racial and ethnic minorities during the COVID-19 pandemic in the United States. Further studies are needed to investigate the mechanisms through which racial and ethnic discrimination can impact lifestyles and to develop potential strategies to address racial and ethnic discrimination as a barrier to healthy lifestyles.

The biological samples of oral genetic diseases and rare diseases are extremely precious. Collecting and preserving these biological samples are helpful to elucidate the mechanisms and improve the level of diagnose and treatment of oral genetic diseases and rare diseases. The standardized construction of biobanks for oral genetic diseases and rare diseases is important for achieving these goals. At present, there is very little information on the construction of these biobanks, and the standards or suggestions for the classification and coding of biological samples from oral and maxillofacial sources, and this is not conducive to the standardization and information construction of biobanks for special oral diseases. This consensus summarizes the background, necessity, principles, and key points of constructing the biobank for oral genetic diseases and rare diseases. On the base of the group standard "Classification and Coding for Human Biomaterial" (GB/T 39768-2021) issued by the National Technical Committee for Standardization of Biological Samples, we suggest 76 new coding numbers for different of biological samples from oral and maxillofacial sources. We hope the consensus may promote the standardization, and smartization on the biobank construction as well as the overall research level of oral genetic diseases and rare diseases in China.
