Objective To analyze and evaluate the implementation effect of tuberculosis prevention and control program in Wuhan, and to provide reference for scientific formulation of tuberculosis prevention and control measures. Methods Using the National Tuberculosis Information Management System, descriptive statistical analysis was carried out on the medical record information of pulmonary tuberculosis patients registered in Wuhan , 2016 - 2021. Results A total of 34 937 cases of pulmonary tuberculosis were registered in Wuhan , with an average annual incidence rate of 49.85/100 000. The incidence rate showed a downward trend year by year, with a statistically significant difference in 2016—2021 (χ²_trend = 708.387, P<0.001). The patients mainly came from referrals, accounting for 71.86%, and the proportion of referrals varied significantly among different years (χ²=355.541, P<0.001). The diagnosis type was mainly pathogenic negative, accounting for 49.12%. The proportion of pathogenic negative had statistically significant difference among different years (χ²=1 354.830, P<0.001). The proportion of patients cured and completed the course of treatment reached 93.98%, with statistically significant differences in the proportions among different years (cured, χ²=1 080.252, P<0.001; completed the treatment course, χ²= 933.655, P<0.001). The sputum examination rate of newly diagnosed patients in each year reached over 90%, and the overall completion rate reached over 95%. The proportion of positive pathogens showed an increasing trend year by year. Conclusion The overall epidemic situation of tuberculosis in Wuhan is declining year by year, and tuberculosis prevention and control work has achieved remarkable results. Active screening in key areas and populations should be strengthened, and prevention and control strategies should be formulated by emphasizing the key and difficult points.

Objective:To explore the efficacy and safety of tislelizumab combined with zanubrutinib in the treatment of refractory diffuse large B-cell lymphoma (DLBCL).Methods:A prospective observational study was conducted. A total of 10 patients with refractory DLBCL admitted to Beijing Chaoyang District Third Ring Cancer Hospital, a specialist medical consortium of Cancer Hospital Chinese Academy of Medical Sciences from November 2020 to February 2023 were prospectively collected. All the 10 refractory DLBCL patients at least received first-line systemic therapy containing rituximab; and they were given tislelizumab 200 mg, intravenous infusion, on day 1 and zanubrutinib 160 mg, orally, twice a day, day 1-day 21, with 21 days as 1 cycle; 6 patients received second-line therapy and 4 patients received ≥ third-line therapy. Subsequent regimens were added with rituximab (375 mg/m 2, intravenous infusion on day 1). The primary endpoint will be reached 12 months after enrollment if there was no disease progression or other events that were scheduled to withdraw from the study. The therapeutic efficacy was summarized at the end of the follow-up in March 2023. Kaplan-Meier method was used to make survival analysis and the adverse reactions were summed up. Results:There were 6 males and 4 females, all at stage Ⅲ-Ⅳ; and age [ M ( Q1, Q3)] was 55 years (50 years, 69 years). All 10 patients completed 90 cycles of treatment with tislelizumab and zanubrutinib, with the cycle number of 8 cycles (2 cycles, 24 cycles). The follow-up time was 19 months (11 months, 28 months); 4 cases achieved complete remission, 3 cases achieved partial remission and 1 case had the stable disease. The progression-free survival was 8.5 months (1.3 months, 27.0 months); the median remission duration time and median overall survival time were not reached. Treatment-related adverse reactions included 2 cases of neutropenia, 1 case of anemia, and 1 case of elevated alanine aminotransferase and aspartate aminotransferase, all of which were grade 1-2. Conclusions:Tislelizumab combined with zanubrutinib has good clinical efficacy and safety in the treatment of refractory DLBCL.

Objective:To establish a scientific and standardized evaluation index system of neonatal breastfeeding nursing quality under the state of mother-infant separation, in order to provide a tool for the detection and management of neonatal breastfeeding nursing quality under mother-infant separation, so as to promote the implementation of breastfeeding in China.Methods:A systematic and comprehensive search of Chinese and English databases was conducted to collect guidelines on neonatal breastfeeding in the state of mother-infant separation. Based on the "structure-process - result" three-dimensional quality structure model, the preliminary draft of evaluation indexes of neonatal breastfeeding nursing quality in the state of mother-infant separation was formed. The evaluation indexes of neonatal breastfeeding nursing quality in the state of mother-infant separation were constructed by Delphi expert correspondence method from July to October, 2023.Results:The effective recovery rates were 95.83% (23/24) and 91.30% (21/23), respectively. The expert authority coefficients were 0.895 and 0.870, respectively. The Kendall harmony coefficients of the whole index were 0.134 and 0.178 (both P<0.01), respectively. The final evaluation index system of neonatal breastfeeding nursing quality under the state of mother-infant separation includes 3 first-level indicators, 18 second-level indicators and 82 third-level indicators. Conclusions:The evaluation index system of neonatal breastfeeding nursing quality in the state of mother-infant separation established in this study is highly scientific and reliable, highlighting the characteristics of neonatal breastfeeding nursing work in the state of mother-infant separation, and can provide a reference for the evaluation of neonatal breastfeeding nursing quality in the state of mother-infant separation.

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 explore the association between peripheral retinal defocus and myopia in adolescents.Methods This study encompassed 192 adolescents(192 right eyes),aged between eight and fifteen years,who sought treatment at Ineye Hospital of Chengdu University of TCM from October 2022 to April 2023.Based on the spherical equiva-lent(SE),the patients were divided into three groups:Emmetropia(E),low myopia(LM),and moderate myopia(MM),with each group comprising 64 patients(64 right eyes).After mydriatic refraction,the SE values were documen-ted.Ocular biological parameters,including axial length(AL),central corneal thickness(CCT),lens thickness(LT),and keratometry values(K1,K2),were obtained using IOL Master 900.Multispectral refraction topography was employed to measure the retinal defocus:positive values indicated hyperopic defocus,while negative ones represented myopic defocus.With the macular fovea as the center,the total retinal defocus value was recorded as TRDV.The ring partition(eccentrici-ty)was divided into 0°-10°、＞10°-20°、＞20°-30°、＞30°-40°、＞40°-53°,which was recorded as RDV-0°-10°,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,and RDV-40°-53°,respectively;the quadrants were recorded as RDV-Superior(RDV-S),RDV-Inferior(RDV-I),RDV-Temporal(RDV-T)and RDV-Nasal(RDV-N),respectively.The variance of RDV across different ranges was analyzed using One-Way ANOVA and non-parametric tests.The associations between SE,AL and RDV were examined using Spearman and Pearson correlation analyses.Results The RDV-20°-30°,RDV-30°-40° and RDV-40°-53° of Groups E,LM and MM all exhibited hyperopic defocus.Statistically significant differences were identi-fied in TRDV,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T and RDV-N among the three groups(all P＜0.05).TRDV,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T,and RDV-N were found to be negatively correlated with SE while positively correlated with AL(all P＜0.05).RDV-0°-10° and RDV-I were uncorrelated with both SE and AL(all P＞0.05);RDV-10°-20° was positively correlated with AL(P=0.012)while uncorrelated with SE(P=0.233).Conclusion Peripheral retinal hyperopic defocus tends to advance with escalating eccentricity and my-opia.Peripheral retinal defocus is asymmetrical.Peripheral(10°-53°),superior,nasal and temporal retinal defocus may be closely related to the development of myopia.

Objective To explore the changes in periretinal defocus and visual quality after femtosecond laser-assis-ted in situ keratomileusis(FS-LASIK).Methods Fifty-one myopic patients(102 eyes)who underwent FS-LASIK at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine from March to May 2023 were selected for the study,including 27 females(54 eyes)and 24 males(48 eyes).The defocus around the retina was measured using a multispectral refraction topography,and the total refraction difference value(TRDV)was recorded.The refraction difference value(RDV)in four quadrants:superior RDV(RDV-S),inferior RDV(RDV-I),nasal RDV(RDV-N),and temporal RDV(RDV-T),as well as the RDV in the concentric ring areas corresponding to 10°,20°,30°,40°,and 53° from the fovea of the mac-ula(represented as RDV 0°-10°,RDV 10°-20°,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53°,respectively)were also re-corded.The objective scattering index(OSI),Strehls ratio(SR),modulation transfer function(MTF)values(represen-ted as 10 c·d-1 MTF,20 c·d-1 MTF,and 30 c·d-1MTF,respectively)and cutoff frequencies(MTF cutoff)at the spa-tial frequencies of 10 c·d-1,20 c·d-1 and 30 c·d-1 were measured and recorded using a visual quality analysis system.The data of corneal vertical trefoil(Z3-3),vertical coma(Z3-1),horizontal coma(Z31),horizontal trefoil(Z33),vertical tetrafoil(Z4-4),vertical secondary astigmatism(Z4-2),spherical aberration(Z40),horizontal secondary astigmatism(Z42),horizontal tetrafoil(Z44),and total higher-order aberration(HOA)were measured and recorded using the iTrace aberration meter.The measurement data of patients before surgery,one month after surgery,and three months after sur-gery were compared,and their correlations were analyzed.Results TRDV,RDV-S,RDV-N,RDV 20°-30°,RDV 30°-40°,and RDV 40°-53° around the retina of patients decreased one month and three months after surgery compared with those be-fore surgery,and the differences were statistically significant(all P＜0.001).There were statistically significant differences in OSI,MTF cutoff,and 10 c·d-1 MTF among patients before surgery,one month after surgery,and three months after surgery(all P＜0.05).There were statistically significant differences in corneal Z3-3,Z3-1,Z31,Z33,Z4-4,Z4-2,Z40,Z42,Z44,and HOA among patients before surgery,one month after surgery,and three months after surgery(all P＜0.001).The Pearson correlation analysis results showed that,ΔRDV 0°-10° was positively correlated with ΔZ3-3,ΔZ31,ΔZ4-2,ΔZ40,and ΔZ42(all P＜0.05);ΔRDV 10°-20° was positively correlated with ΔZ4-4 and ΔZ4-2(both P＜0.05);ΔRDV 20°-30° was positively correlated with ΔZ4-4 and ΔZ44(both P＜0.05);ΔTRDV and ΔRDV 40°-53° were negatively correla-ted with ΔHOA(both P＜0.05).ΔRDV-S and ΔZ3-1 were negatively correlated with ΔHOA(both P＜0.05)and positively correlated with ΔZ44(P＜0.05);ΔRDV-N was positively correlated with ΔZ4-4(P＜0.05).Conclusion FS-LASIK can reduce periretinal hyperopic defocus in myopic patients,but it introduces corneal HOA,and there is a certain correlation between the two.

Objective:To explore potential biomarkers that can predict the clinical efficacy of PD-1/PD-L1 inhibitors in malig-nancies.Methods:The PubMed,Web of Science,CNKI,Wanfang and VIP databases were searched from the establishment of the database to September 20,2022.After literature screening,data extraction and the risk of bias were evaluated independently by two evaluators,the Meta-analysis was performed using RevMan5.4 and STATA16.0 software.Results:This paper included 18 studies with a total of 4 018 patients.Tumor patients with a high tumor mutational burden(TMB)were found to have higher overall survival(OS)(P=0.003,P=0.01)and progression-free survival(PFS)(P=0.000 2,P=0.04)with PD-1/PD-L1 inhibitors within 1 year and 2 years of follow-up.At different follow-up times,with 1%as the critical value,there was no statistical significance in the level of PD-L1 ex-pression as a biomarker for predicting OS and PFS of PD-1/PD-L1 inhibitors(P>0.05).Conclusion:TMB can be used as a biological indicator to predict the clinical efficacy of PD-1/PD-L1 inhibitors in patients with malignant tumors within 2 years after treatment,but whether its efficacy can last longer remains to be further studied.PD-L1 single test is not currently a biomarker for predicting the bene-fit of PD-1/PD-L1 inhibitors.

Objective To analyze the peripheral defocus of the retina in myopic children wearing orthokeratology lenses(OK lenses)using multispectral refraction topography(MRT).Methods A retrospective study was conducted.A total of 128 eyes of 128 myopic children(right eye)who got OK lenses in Ineye Hospital of Chengdu University of TCM from January to April 2021 were included.The steep keratometry(Ks),flat keratometry(Kf),eccentricity at the meridian of Ks and eccentricity at the meridian of Kf were measured by corneal topography before wearing OK lenses.The central corneal thickness before wearing OK lenses,baseline axial length(AL1)and axial length(AL2)after wearing OK lenses for 1 year were measured by optical biometer,and retinal defocus value(RDV)after wearing OK lenses for 1 year was meas-ured by MRT.According to the change in axial length(CAL)after wearing OK lenses for 1 year,subjects were divided into the SAL group(CAL≤0.3 mm)and LAL group(CAL＞0.3 mm).The peripheral RDV in the range of 0°-10°,＞10°-20°,＞20°-30°,＞30°-40°,and＞40°-53°(RDV0°-10°,RDV10°-20°,RDV20°-30°,RDV30°-40°,RDV40°-53°),av-erage RDV in the range of 0°-53°,and average RDVs in the superior,inferior,temporal and nasal quadrants(RDV-S,RDV-I,RDV-T and RDV-N)of both groups were compared after wearing OK lenses for 1 year.In addition,the effect of RDV in different peripheral retinal regions on AL growth was analyzed.Results After wearing OK lenses for 1 year,the peripheral RDV20°-30°,RDV30°-40°,RDV40°-53°,TRDV,RDV-I and RDV-T were higher in the LAL group than those in the SAL group(all P＜0.05).Correlation analysis showed that AL1 was negatively correlated with CAL(P＜0.05),whereas age,peripheral RDV0°-10°,RDV-S,RDV-N and other ocular biological parameters were not correlated with CAL(all P＞0.05).The peripheral RDV10°-20°,RDV20°-30°,RDV30°-40°,RDV40°-53°,TRDV,RDV-I and RDV-T were positively correlated with CAL(all P＜0.05).Conclusion Peripheral retinal defocus in the range of 10°-53° in myopic children is closely related to AL growth.The lower the RDV,the slower the AL growth.

Objective:To investigate the effect of peripheral plus ring size and its potential associations with pupil diameter (PD) on axial length (AL) elongation in myopic patients after wearing orthokeratology lenses.Methods:A case-control study was conducted.One hundred eyes from 100 myopic patients who underwent orthokeratolokgy lenses fitting were enrolled at Beijing Ming Vision and Ophthalmology from January to June 2020.AL and central corneal thickness (CCT) measurements were obtained using Lenstar LS900 ocular biometry, and steep keratometry (Ks), flat keratometry (Kf) were assessed using the TMS-4 corneal topographer.The patients were divided into larger peripheral plus ring diameter (LPPRD) group consisting of 55 eyes with PD0.05). There was no significant difference in PD at different time points before and after wearing orthokeratology lenses between the two groups ( Fgroup=1.133, P=0.293; Ftime=231.427, P=0.112). Conclusions:The size of peripheral plus ring and its relationship with PD are key factors influencing the AL elongation rate in myopic patients after wearing orthokeratology lenses.With smaller PPRD, patients have slower AL elongation and better myopia control.

Objective:To investigate the status of corneal epithelial remodeling and changes in corneal aberration after femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and FS-LASIK combined with corneal collagen cross-linking (FS-LASIK Xtra), and to analyze the relationship between corneal epithelial thickness (CET) and corneal aberration.Methods:A cohort study was conducted.A total of 172 patients (172 eyes) who underwent FS-LASIK at Yinhai Eye Hospital of Chengdu University of Traditional Chinese Medicine were enrolled from June 2021 to February 2022.The 172 eyes were divided into FS-LASIK group (94 eyes) and FS-LASIK Xtra group (78 eyes) according to the surgical procedure, with a total follow-up of 6 months.The cornea was divided into a central 2-mm ring and a ring of 2-5 mm centered on the central cornea.CET at 9 regions in the central 0-5 mm area was measured by OCT before and at 1, 3 and 6 months after surgery, and the corneal higher-order aberration (HOA) was measured by the iTrace visual function analyzer.The main outcomes were the increase in CET (ΔCET), and corneal HOA at 6 months after surgery.The relationship between central corneal ΔCET and corneal aberration was analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Yinhai Eye Hospital of Chengdu University of Traditional Chinese Medicine (No.2021yh-009). Written informed consent was obtained from each subject.Results:At 1, 3 and 6 months after surgery, the central, superior, superior nasal, nasal, inferior nasal, inferior, inferior temporal, temporal and superior temporal ΔCET were significantly smaller in FS-LASIK Xtra group than in FS-LASIK group (all at P<0.05). In FS-LASIK Xtra group, 6-month postoperative central, superior, superior nasal, inferior and inferior temporal ΔCET were significantly larger than those at 1 month after surgery, and 3- and 6-month postoperative temporal ΔCET were significantly larger than that at 1 month after surgery, and 6-month postoperative superior temporal ΔCET was significantly larger than those at 1 and 3 months after surgery (all at P<0.05). In FS-LASIK group, 3- and 6-month postoperative central, superior, inferior and inferior temporal ΔCET were significantly larger than those at 1 month after surgery, and 6-month postoperative superior nasal ΔCET was significantly larger than that at 3 months after surgery, and 6-month postoperative nasal, inferior nasal, temporal, superior temporal ΔCET were significantly larger than those at 1 and 3 months after surgery (all at P<0.05). There was no significant difference in vertical trefoil, vertical and horizontal coma changes at different time points after surgery between both groups (vertical trefoil: χ2group=4.27, P=0.118; χ2time=0.01, P>0.05.vertical coma: χ2group=5.74, P=0.057; χ2time=0.08, P=0.957.horizontal coma: χ2group=3.97, P=0.137; χ2time=0.51, P=0.773). The tilted trefoil changes at 1, 3 and 6 months after surgery of FS-LASIK Xtra group were significantly larger than those of FS-LASIK group (all at P<0.05). The 6-month spherical aberration change in FS-LASIK Xtra group was significantly higher than that at 1 month after surgery, and the 6-month spherical aberration change in FS-LASIK group was significantly higher than that at 1 and 3 months after surgery (all at P<0.05). The 6-month total HOA change in FS-LASIK group was significantly lower than that at 1 and 3 months after surgery (all at P<0.05). In FS-LASIK group, central corneal ΔCET was weakly positively correlated with spherical aberration at 1 and 6 months after surgery ( rs=0.257, P=0.008; rs=0.244, P=0.012), and was weakly positively correlated with total HOA ( rs=0.253, P=0.009; rs=0.279, P=0.004). Conclusions:The postoperative ΔCET after FS-LASIK Xtra is smaller than that after FS-LASIK, but the homogeneity of ΔCET in each region is similar between the two groups.The changes in corneal HOA after surgery are similar in both groups, and there is a certain association between the overall epithelial distribution and corneal aberration.
