Objective: To investigate the distribution of pupil diameter and its association with myopia in school age children, providing ideas into the mechanisms of the role of pupil diameter in the onset and development of myopia. Methods: Adopting a combination of stratified cluster random sampling and convenience sampling method, 3 839 children from six schools in Shandong Province were included in September 2021. Pupil diameters distribution was analyzed by age, sex, and myopic status. Pearson correlation analysis was used to assess the relationship between pupil diameter and cycloplegic spherical equivalent (SE), as well as axial length (AL) and other variables. Propensity score matching (PSM) was applied to match myopic and non myopic children at a 1∶1 ratio based on age and sex. A generalized linear model (GLM) was constructed with pupil diameter as the dependent variable to identify independent factors influencing pupil size and its association with myopia. Results: The mean pupil diameter of school age children was (5.77±0.80)mm. Pupil diameter exhibited a significant increasing trend with age ( F =49.34， P trend ＜ 0.01). Myopic children had a significantly larger mean pupil diameter [(6.10±0.73)mm] compared to non myopic children [(5.62±0.79)mm] with a statistically significant difference( t=18.10, P <0.01). Multivariable GLM analysis, adjusted for age, amplitude of accommodation, and uncorrected visual acuity, revealed a negative correlation between pupil diameter and cycloplegic SE (before PSM: β =-0.089, after PSM: β =-0.063, both P ＜0.01). Conclusions Myopic school age children exhibite larger pupil diameters than their non myopic counterparts. Pupil diameter may serve as a potential indicator for monitoring myopia development in school age children.

Objectives To evaluate the complications predicting efficacy of the American College of Surgeons(ACS)National Surgical Quality Improvement Program(NSQIP)surgical risk calculator for cervical cancer patients undergoing open radical hysterectomy in China.Methods This study enrolled the cervical cancer patients(139 cases)undertaken open radical hysterectomy at Women's Hospital of Nanjing Medical University from Janu-ary to December in 2021.Preoperative risk factors were abstracted from medical records and the surgical risk scores were calculated using ACS NSQIP surgical risk calculator.The association between risk scores and actual outcomes were assessed using logistic regression together with the c-statistic(area under ROC)and Brier score.Results The ACSNSQIP calculator did not predict accurately for serious complications,any complications,venous thrombo-embolism(VTE),readmission,return operation room and surgical site infection(SSI)compared with actual out-comes.There was significantly difference in the predicted and actual length of stay(3.93±0.42 days vs.13.11±4.71 days,P<0.001).Conclusions The ACS NSQIP surgical risk calculator failed to predict the postoperative complications and the length of hospital stay for cervical cancer patients undergoing open radical hysterectomy.

OBJECTIVE To systematically evaluate the incidence of anti-tuberculosis drug-induced liver injury （ATB-DILI） and its risk factors. METHODS PubMed， Embase， the Cochrane Library， Web of Science， China Knowledge Network， VIP， Wanfang data and China Biomedical Literature Database were searched to collect cohort studies and case-control studies on the incidence and risk factors of ATB-DILI from the establishment of the database to 31 May 2024. After screening literature， extracting data and evaluating the quality of literature， meta-analysis was performed using Stata 17.0 and RevMan 5.3 software. RESULTS A total of 26 literature involving 38 971 patients were included， of which 4 106 patients suffered from ATB-DILI. Meta-analysis showed that the incidence of ATB-DILI was 12.94% [95%CI （10.82%，15.06%）， P＜0.001]； subgroup analysis showed that the incidence of ATB-DILI in cohort studies， Chinese studies and pediatric patients was higher （P＜0.001）. Age≥60 years， abnormal body mass index， alcoholism， smoking， history of liver disease， hepatitis B surface antigen positivity， extrapulmonary tuberculosis， malnutrition， hypoproteinemia， cardiovascular disease， diabetes mellitus， systemic lupus erythematosus， no prophylactic use of hepatoprotective drugs， and high baseline alanine transaminase levels were risk factors for developing ATB-DILI （P＜0.05）. Sensitivity analysis and publication bias analysis showed that the results obtained in this study were relatively robust. CONCLUSIONS The incidence of ATB-DILI in tuberculosis patients is 12.94%. Age≥60 years， abnormal body mass index， alcoholism， smoking， history of liver disease， hepatitis B surface antigen positivity， extrapulmonary tuberculosis， malnutrition， hypoproteinaemia， cardiovascular disease， diabetes mellitus， systemic lupus erythematosus， non-prophylactic use of hepatoprotective medications， and high baseline levels of alanine transaminase are the risk factors for developing ATB-DILI.

BACKGROUND:As a bone replacement and filling material,calcium phosphate stone bone cement has good biocompatibility,bone conductivity,and other advantages,especially its better biodegradability compared to other calcium phosphate bone cements.It has important application value in bone repair.However,due to its limitations such as insufficient mechanical properties,fast solidification reaction,and poor injection performance,it is currently only suitable for the repair of non weight-bearing bone. OBJECTIVE:To explore the modification of brushite cements with bioactive ions(metal and non metal ions)to expand its application range. METHODS:The author used PubMed,ScienceDirect,CNKI,and WanFang to search the literature published between 2018 and 2023 with the search terms"metal ion,iron,copper,strontium,magnesium,zinc,non-metal ion,modification,bone,brushite cements"in Chinese and"metal ion,iron,Fe,copper,Cu,strontium,Sr,magnesium,Mg,zinc,Zn,non-metal ion,modification,bone,brushite cements"in English.After reading titles and abstracts,the articles were initially screened,and irrelevant and duplicate articles were excluded.Finally,64 articles were included for review. RESULTS AND CONCLUSION:(1)Bioactive ions affect the hydration process of calcium phosphate bone cement.Different ions are substituted by ions and incorporated into the crystal structure of calcium phosphate bone cement,changing the crystal morphology of the cement and causing changes in physical and chemical properties such as setting time,injectability,and compressive strength.(2)Ionic modified calcium phosphate bone cement produces different ion release effects due to different crystal structures.Different types of ions have properties such as promoting angiogenesis/osteogenesis,antibacterial,anti-tumor,etc.In addition,calcium phosphate bone cement has good biodegradability,which has great advantages for the performance of various ions.(3)The physicochemical properties of calcium phosphate bone cement modified with different ions are as follows:iron,copper,strontium,magnesium,zinc,silver,and cobalt can prolong the setting time.Strontium,and magnesium can improve injection performance.Copper,strontium,magnesium,silver and silicon can enhance compressive strength.The ions that can simultaneously improve the three physical and chemical properties of calcium phosphate bone cement include strontium and magnesium.Good physical and chemical properties are a prerequisite for clinical application,so improving the setting time,injectability,compressive strength,and other properties of calcium phosphate bone cement with ions is of great significance for the research and application of bone cement.(4)The biological properties of calcium phosphate bone cement modified with different ions are as follows:copper,strontium,magnesium,zinc,cobalt,lithium,selenium,and silicon have promoting angiogenesis/osteogenic effects.Iron,copper,magnesium,zinc,and silver have antibacterial properties.Magnesium ions have anti-inflammatory properties.Copper and selenium have anti-tumor properties.(5)In summary,magnesium ions can improve the setting time,injectability,and compressive strength of calcium phosphate bone cement,while also promoting neovascularization/osteogenesis,antibacterial properties,and have good application prospects for the treatment of bone defects with concurrent infections.In addition,copper also has anti-tumor properties,so copper ions have great potential in the treatment of bone defects caused by infections and tumors.However,relevant research is still in the basic research stage,and the effects of different ion doping concentrations and synthesis conditions on the physicochemical properties of calcium phosphate bone cement need to be further explored.At the same time,the impact of biological properties also needs to be studied and observed for a longer period of time.

Objective To conduct a network meta-analysis on the effectiveness of first-line immunotherapy on patients with brain metastases from advanced non-small cell lung cancer(NSCLC).Methods Two investigators conducted a computerized search of Pubmed,Embase,Cochrane,and other databases to screen the literature,extract the information,and assess the risk of bias of the included studies.The included clinical trials were statistically analyzed using R(4.1.3)software.For the study outcome indicators OS and PFS,the risk ratios(HRs),and the 95%confidence intervals(CIs)were extracted from the included studies and logarithmically transformed into effect analysis statistics.Results Six randomized controlled trials were finally included,including 327 patients with non-excludable NSCLC brain metastases.Network meta-analysis suggested that PD-1 inhibitor+CTLA-4 was more advantageous than the conventional chemotherapy for enhancing patients'OS(HR:0.13,95%CI:0.03-0.71),followed by PD-L1 inhibitor(HR:0.17,95%CI:0.04-0.74)and PD-1 inhibitor+chemotherapy(HR:0.36,95%CI:0.2-0.63).PD-1 inhibitor+CTLA-4 was also more advantageous(HR:0.37,95%CI:0.15-0.93)than the conventional chemotherapy for boosting patients'PFS,followed by PD-L1 inhibitor+chemotherapy(HR:0.44,95%CI:0.29-0.66)and PD-1 inhibitor(HR:0.48,95%CI:0.27-0.86).Conclusion Immune checkpoint inhibitor therapy improves the survival of patients with brain metastases from advanced NSCLC.In particular,the combination of PD-1 inhibitor and CTLA-4 inhibitor show excellent survival benefit.

Objective:To explore the current status of readiness for young and middle-aged maintenance hemodialysis (MHD) patients to return to work and analyze its influencing factors, with the aim of providing reference for the evaluation and intervention of patients returning to work.Methods:From October to December 2022, convenience sampling was used to select 425 patients from six hospitals in the urban area of Yangzhou as the subject. A cross-sectional survey was conducted using the General Information Questionnaire, Readiness for Return-To-Work Scale (RRTWS), Distress Disclosure Index (DDI) and Perceived Social Support Scale (PSSS). Binary Logistic regression was used to analyze the influencing factors of returning to work.Results:Among 425 young and middle-aged patients undergoing MHD, 105 (24.7%) returned to work, of which 79 (75.2%) were in the uncertain maintenance stage and 26 (24.8%) were in the active maintenance stage. 320 did not return to work, including 148 (46.3%) in the pre-intention stage, 86 (26.9%) in the intention stage, 42 (13.1%) in the action preparation self-evaluation stage, and 44 (13.8%) in the action preparation behavior stage. Age, per capita monthly income of the family, number of comorbidities, level of self-disclosure, and level of perceived social support were factors that affected patients' readiness to return to work.Conclusions:The rate of young and middle-aged MHD patients returning to work needs to be improved. The return of patients to work is influenced by multiple factors. Medical and nursing staff should focus on patients who are old, have low per capita monthly income of the family, and have a large number of comorbidities. Targeted interventions and guidance should be provided to patients, such as self-disclosure training and improving their perceived social support, in order to increase the rate of patients returning to work rate.

OBJECTIVE To excavate and evaluate β-blockers associated with acute renal failure（ARF）signal. METHODS Using the report odds ratio （ROR）method and Bayesian confidence interval progressive neural network （BCPNN）method，signal detection and analysis were performed for 4 kinds of β-blockers（metoprolol，bisoprolol，atenolol，nebivolol）associated with ARF Δ 基金项目：重庆市临床药学重点专科建设项目 （No.渝卫办发 in FDA adverse event reporting system （FAERS）from the two 〔2020〕68号）；重庆医科大学未来医学青年创新团队发展支持计划项 dimensions of Standard International Dictionary of Medical 目（No.W0081） Terms （MedDRA） analysis query （SMQ） term set and ＊药师，硕士研究生。研究方向：药物警戒。电话：023-68485161。 preferred term （PT） level terms.

RESULTS Totally 14 328 戒。电话：023-63625666。E-mail：jiayuntaomail@hospital.cqmu.edu.cn ARF reports of 4 kinds of β-blockers were retrieved within the ·1380· China Pharmacy 2022Vol. 33 No. 11 中国药房 2022年第33卷第11期 narrow sense of “acute renal failure ”in SMQ term set ，of which men （6 964）were more than women （6 206）. The age of patients was mainly concentrated in the middle-aged and elderly （≥45 years old ），and serious adverse events accounted for 77.23％. The results of signal retrieval based on SMQ term set showed that ROR values and 95％ confidence intervals of metoprolol ，bisoprolol， atenolol and nebivolol detected by ROR method were 2.58（2.51，2.65），5.30（5.14，5.47），2.80（2.69，2.91）and 3.28（3.04， 3.53）respectively. The signal components （IC）detected by BCPNN method and the lower limit of IC were 1.29（1.25），2.26 （2.22），1.42（1.36）and 1.64（1.53）respectively，suggesting suspicious signals were detected in these four kinds of β-blockers associated ARF. The results of signal detection based on PT level terms showed that 37 positive signals were detected by ROR method，38 positive signals were detected by BCPNN method ，and 36 suspicious signals were detected by the two methods at the same time. For each drug ，12 suspicious signals of metoprolol were detected at the same time ，9 suspicious signals of bisoprolol and atenolol were detected at the same time ，and 6 suspicious signals of nebivolol were detected at the same time ；the number and type of signals were different among the 4 kinds of drug. CONCLUSIONS Four kinds of β-blockers may cause ARF. Compared with metoprolol and atenolol ，bisoprolol and nebivolol have strong statistical correlation with ARF ，suggesting that medical personnel should pay attention to the possible renal related adverse reactions of these drugs in the process of clinical use.

OBJECTIVE: To explore the prognostic factors of patients with unresectable liver metastasis colorectal cancer after failed conversion chemotherapy. METHODS: A retrospective, case-controlled study was performed. Study subjects were 105 patients who were diagnosed with synchronous liver metastasis colorectal cancer after failed chemotherapy (metastasis evaluated as unresectable after the conversion chemotherapy) at Xinhua Hospital, Shanghai Jiaotong University from January 2012 to December 2015. Overall survival(OS) was retrospectively analyzed using Kaplan-Meier method. Log-rank test was used to compare survival among groups. Univariate and multivariate analysis was conducted for prognosis using Cox regression model. RESULTS: Of 105 cases,70 were male and 35 were female with median age of 60 years old. Twenty-one patients had right colon cancer, 41 had left colon cancer, 42 had rectal cancer and 1 had synchronous cancers(sigmoid colon and rectum). One hundred and two (97.1%) patients were cT3-4 and 90 patients were cN+ (imaging diagnosis). Eighty-nine (84.8%) patients were loaded with 2 or more liver metastases with the median maximum diameter of 48.3 mm. The patients were followed up for 3 to 43 months from the day of diagnosis. The median OS was 11 months (interquartile range, 8-18). The median OS of patients with cN0, cN1 and cN2 stage was 17, 13 and 10 months, respectively(P=0.026). The median OS of patients with single lesion, 2-3 lesions, 4-10 lesions and more than 10 lesions was 15, 15, 17 and 9 months, respectively (P=0.002). OS of patients with maximum diameter of liver metastatic lesion ≤ 50 mm, 51-100 mm and >100 mm was 15, 10 and 8 months, respectively(P=0.003). The median OS of patients with chemotherapy response of partial response (PR), stable disease (SD) and progressive disease (PD) was 17, 14 and 8 months, respectively(P<0.001). OS was 17 months in patients receiving second line chemotherapy and was 10 months in those without second line chemotherapy (P<0.001). OS in patients undergoing primary tumor resection was 13 month and in those without primary tumor resection was 9 months; the difference was not significant (P=0.060). Multivariate analysis showed that cN2(HR=2.115, 95%CI:1.089-4.109, P=0.027), the maximum diameter of liver metastatic lesion more than 100 mm (HR=3.112, 95%CI:1.455-6.657, P=0.003), chemotherapy response of PD (HR=4.435, 95%CI:2.506-7.533,P<0.001) and without second line chemotherapy(HR=4.432,95%CI:2.186-8.986, P=0.010) were independent prognostic factors. CONCLUSIONS For patients with unresectable liver metastasis from colorectal cancer after failed conversion chemotherapy, prognostic factors include cN2, the maximum diameter of liver metastatic lesion, chemotherapy response and second line chemotherapy. Whether the resection of primary tumor can prolong OS further study.

Objective To investigate the relationship between prothrombin fragment 1+2 (F1+2) and peripherally inserted central catheter (PICC) associated thrombosis in cervical cancer patients, and provide certain clinical basis of early prevention in peripherally inserted central catheter associated thrombosis in cervical cancer patients. Methods One hundred and forty cervical patients with PICC were enrolled in this study, and they were divided into thrombosis group (35 patients) and non-thrombosis group (105 patients). The level of F1+2 was examined using enzyme-linked immunoassay, and was analyzed according to the clinic features. Results The level of F1+2 was correlated with clinical stage (r = 0.640, P = 0.004);but was not correlated with age, type of tumor and concurrent radiochemotherapy (P>0.05). The level of F1+2 in thrombosis group was (520.343 ± 121.759) pmol/L, in non- thrombosis group was (388.361 ± 104.873) pmol/L, and there was significant difference (P =0.001). The multi-factors Logistic analysis showed that the level of F1+2 (OR=1.011, P=0.001) and age (OR = 21.025, P = 0.031) were independent risk factors for the PICC associated with thrombosis in cervical cancer. Conclusions The level of F1+2 is closely related with clinical stage and PICC associated thrombosis, and it is an independent risk factor for the PICC associated with thrombosis in cervical cancer.
