BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To explore the effect of play-based communication and behavior intervention (PCBI) on internalizing and externalizing behaviors in children with autism spectrum disorder (ASD).Methods:From November 2018 to November 2021, 90 ASD children aged 8-30 months who registered in the Child Mental Health Research Center of the Affiliated Brain Hospital of Nanjing Medical University for PCBI ultra-early intervention training were selected and randomly assigned to the intervention group( n=60) and the waiting group( n=30) according to the ratio of 2∶1.Behavioral videos of free play between children and caregivers were collected before and after the 12-week intervention and the behavioral observation and analysis system (Observer XT) was used to code the parent-child interaction status and children's internalizing and externalizing behaviors.SPSS 23.0 statistical software were used and the data were analyzed by t-test, chi-square test, Pearson correlation analysis and multiple linear stepwise regression analysis. Results:After the intervention, the children in the intervention group had improved internalizing and externalizing behaviors (2.43±2.22, 1.88±1.91) compared with those before the intervention (4.82±3.37, 3.68±5.68), and the difference was statistically significant ( t=4.66, 2.60, both P<0.05). The children in the waiting group had no significant difference in internalizing and externalizing behaviors before (4.23±2.47, 4.00±2.18) and after intervention (4.37±2.57, 4.67±3.72) ( t=-0.23, -0.83, both P>0.05). After intervention, the children in the intervention group had fewer internalizing and externalizing behaviors than those in the waiting group, and the difference was statistically significant ( t=-3.70, -4.71, both P<0.05). The differences in internalizing behaviors (2.38±3.96, 1.80±5.37) and externalizing behaviors (1.80±5.37, -0.67±4.38) between the two groups before and after the intervention were statistically significant ( t=3.03, 2.18, both P<0.05). The results of multiple linear stepwise regression showed that the negative interaction of caregivers ( β=0.29, P<0.01) was a risk factor for internalizing behaviors.The negative interaction of children ( β=0.45, P<0.01) was a risk factor for externalizing behaviors, and the child's object status ( β=-0.30, P<0.01) and binary interaction ( β=-0.39, P<0.01) were protective factors for externalizing behaviors.In the intervention group, active child interaction, active caregiver interaction, and binary interaction increased after the intervention ( t=-6.77, -4.58, -7.72, all P<0.05), while the child's object status and the caregiver's negative interaction decreased ( t=3.37, 4.30, both P<0.05). Conclusion:The PCBI ultra-early intervention can effectively improve the internalizing and externalizing behaviors of ASD children.Improvements in internalizing behaviors may work by reducing negative caregiver interactions, and improvements in externalizing behaviors may work by increasing parent-child binary interactions.

Objective:To investigate the distribution characteristics and trends of mortality and spatial aggregation of gastric cancer in Shandong Province from 1970 to 2013.Methods:The mortality data of gastric cancer from 1970 to 1974, 1990 to 1992 and 2004 to 2005 were collected from the first, second and third retrospective sampling survey of causes of death in Shandong Province, respectively. The mortality data of gastric cancer from 2011 to 2013 were collected from the all-cause surveillance data of Shandong Province. The crude mortality rate and age-standardized mortality rate were used to describe the death level of gastric cancer. The age-standardized mortality rate of Shandong Province was calculated based on Segi′s world standard population, and the age-standardized mortality rate of counties (cities and districts) was calculated based on the Chinese population in 1964.The factors influencing the difference of gastric cancer mortality in different periods were decomposed by using the method of differential decomposition of mortality, and the contributions of population and non-population factors in different periods were estimated.Using ArcGIS 10.2 software, the death level of gastric cancer in different counties (cities and districts) in Shandong province from 1970 to 1974 and 2011 to 2013 were visualized. DeoDa 1.12 software was used for global and local spatial autocorrelation analysis.Results:The crude death rate and age-standardized death rate of gastric cancer in Shandong province increased firstly and then decreased during 1970-2013, and the crude death rate of gastric cancer increased from 18.33/100 000 in 1970-1974 to 28.51/100 000 in 2011-2013. Segi′s age-standardized mortality rate for gastric cancer decreased from 20.94 per 100 000 in 1970-1974 to 18.17 per 100 000 in 2011-2013.From 1990 to 1992, from 2004 to 2005 and from 2011 to 2013, the contribution value of non-population factors to the increase of crude gc mortality was 95.59%, 48.45% and -20.57%, respectively, showing a continuous downward trend. The Moran′s I index of crude mortality of gastric cancer in Shandong province from 1970 to 1974 and from 2011 to 2013 were 0.77 and 0.57, respectively, and the Moran′s I index of age-normalized mortality was 0.75 and 0.44, respectively. Local autocorrelation analysis showed that there were 31 and 19 high aged-mortality areas of gastric cancer in 1970-1974 and 2011-2013 respectively, and 7 overlapping counties (cities and districts), 6 of which were located in Jiaodong area. Conclusion:The crude mortality and age-standardized mortality of gastric cancer in Shandong province increased first and then decreased from 1970 to 2013, and the distribution of gastric cancer mortality had obvious spatial aggregation and changed with time.

Objective:Breast cancer has been the first cancer among women with the incidence increasing gradually. In September 2016, the Breast Cancer Cohort Study in Chinese Women (BCCS-CW) was initiated, aiming to establish a standardized and sharable breast cancer-specific cohort by integrating the existing cohort resource and improving the quality of follow-up. The BCCS-CW may provide a research basis and platform for the precision prevention and treatment of breast cancer in etiology identification, prevention, early diagnosis, treatment, and prognosis prediction.Methods:We conducted a population-based perspective cohort by questionnaire interview, anthropometry, biological specimens, breast ultrasound and mammography. The cohort was followed by using regional health surveillance and ad hoc survey.Results:Finally, BCCS-CW included 112 118 women, in which 55 419 women completed the standardized investigation and blood specimens were collected from 54 304 women. The mean age of participants was 51.7 years old, 62.7% were overweight or obese, and 48.9% were menopausal.Conclusion:The BCCS-CW will provide population-based cohort resource and research platform for the precise prevention and treatment of breast cancer in Chinese women.

Objective: Children with autism spectrum disorder(ASD) who participated in the " Play-based Communication and Behavior Intervention(PCBI)" were studied in order to evaluate the impact of caregiver factors on the efficacy of the PCBI very early intervention model systematically. Methods: Seventy-six children with ASD aged 8-30 months were recruited in this study at Brain Hospital Affiliated to Nanjing Medical University form December 2017 to June 2018, and they were trained for PCBI very early intervention.The Autism Treatment Evaluation Checklist (ATEC) and the Gesell Developmental Schedules were used to evaluate the efficacy of the PCBI very early intervention.Parenting Stress Index Short Form, General Self-Efficacy Scale and the self-developed Caregiver Training Course Evaluation Scale and the Homework Completion Level Scale were used to assess the level of parental stress, self-efficacy, curriculum satisfaction and acceptance.A pair of sample t-test was used to analyze the ASD symptoms, developmental level and caregiver factors of ASD children before and after intervention.Multivariate regression analysis was used to analyze the caregiver factors and the effects of PCBI very early intervention. Results: (1) At the end of 12 weeks of PCBI very early intervention, the score of the ATEC (17.36±15.98) was lower than that before intervention (78.43±22.84), and the difference was statistically significant(P<0.05); the adaptive developmental quotient(5.90±15.45), the fine action developmental quotient(5.13±19.89), the language developmental quotient (12.43±20.60) and the personal social developmental quotient(4.79±16.02) scores of the Gesell Developmental Schedules were higher than those before intervention (73.08±20.54, 77.33±23.63, 52.24±19.12, 71.79±20.81), and the differences were statistically significant (all P<0.05). (2) At the end of PCBI very early intervention, there was a significant decrease in the scores of Parenting Stress Index Short Form, and the differences were statistically significant (4.84±14.69 vs.94.05±29.67, P<0.05). (3) Acceptance of the intervention model, and mastery of the skills in the caregiver factors had a positive predictive effect on the effect of PCBI very early intervention (t=3.068, 10.468, all P<0.05). Conclusions PCBI very early intervention can effectively reduce the parenting pressure of the caregivers, and in the PCBI very early intervention, the better the mastery of skills and the completion of homework, the better the efficacy of intervention.

Objective To evaluate the performance of an enhanced fluorescent staining for the rapid diagnosis of invasive mycosis, especially rare cases, considering the traditional culture method always leads to delays in clinical diagnosis for its time consuming. Methods Cases of invasive mycosis identified by fluorescent staining in our hospital from September, 2017 to September, 2018 were retrospectively analyzed. Three rare in-vasive infections were reported in this study. Clinical specimens were pretreated using standard procedures and then smeared on slides along with the enhanced fluorescent dye. Species of the pathogens were identified accord-ing to their morphology under fluorescent microscope. The traditional culture method was used as a standard method to identify the pathogenic species based on their colony morphology, followed by PCR and sequencing analysis for further confirmation. Results Three cases of invasive mycosis caused by rare pathogens of Talaro-myces marneffei, Mucorales and Prototheca were rapidly diagnosed with the fluorescent staining method. Sequen-cing results indicated the species were Talaromyces marneffei, Rhizopus arrhizus and Prototheca wickerhamii. Conclusions Fluorescent staining is a rapid, economic and direct method for the diagnosis of invasive mycosis. The morphology of fungi is clear and easy to identify after fluorescence staining, which could be used for indica-tive diagnosis of highly suspected invasive mycosis and serve as an important complement to the traditional cul-ture method, especially for the diagnosis of rare or uncultured fungal pathogens.

Objective To compare and analyze the short-term effect of play-based communication and behavior intervention (PCBI) and applied behavioral analysis (ABA) on the treatment of toddlers with autism spectrum disorder (ASD).Methods Seventy-four ASD toddlers aged from 19 to 30 months were recruited in Nanjing Brain Hospital Affiliated to Nanjing Medical University from November 2017 to May 2018.The toddlers who participated in this study were randomly assigned into PCBI group and ABA group,then they were intervened weekly by PCBI or ABA for a total of 12 weeks.Portage Early Development Checklist and autism treatment evaluation checklist (ATEC) were used to estimate the toddlers' developmental level and the treatment efficacy respectively.The t-test was used to reveal whether there was significant difference between the 2 groups before and after intervention.Results (1) Compared with the ABA group,there was a significant increase in cognitive scores (△PCBI =9.03 scores,△ABA =4.27 scores,t =3.997) and a significant decrease in social behavior scores (△PCBI =8.87 scores,△ABA =16.91 scores,t =-4.022) of the Portage Early Development Checklist after 12 weeks of intervention in the PCBI group,and there were statistically significant differences(all P ＜ 0.001);while the total score and the scores of language,movement,and self-care subscale of Portage Early Development Checklist were also increased after PCBI intervention but without significant differences (all P ＞ 0.05).(2)Compared with the ABA group,after 12 weeks of PC BI intervention,the scores of social contact,perception,behavior of ATEC were decreased,but the difference was not significant (P ＞ 0.05);the total score of ATEC scale(△PCBI total =14.89 scores,△ABA total =22.22 scores,t =2.209)and the scores of language subscale(△PCBI language =2.89 scores,△ ABA language =6.43 scores,t =2.515) were decreased significantly,and there were statistically significant differences (all P ＜ 0.05).Conclusions After 12 weeks of the very early intervention of PCBI,the ASD toddlers all improved in clinical symptoms and developmental level.Compared with ABA intervention,PCBI very early intervention with parental guidance was comparable in short term efficacy,and PCBI was not taking up as much medical rehabilitation resources as ABA.

Objective To explore the efficacy and safety of apatinib combined with S-1 in patients with advanced NSCLC without sensitive gene mutation or unknown mutation status.Methods One hundred and four patients with advanced NSCLC without sensitive gene mutation or unknown mutation status were selected from the oncology department of the First Hospital of Qinhuangdao City,Hebei Province from April 2015 to April 2017.All patients refused intravenous chemotherapy.One hundred and four patients were randomly divided into treatment group (apatinib combined with S-1 group) and control group (S-1 alone group) by 1:1 digital method.However,two patients in the treatment group transferred to the control group for personal reasons.There is 50 cases in apatinib combined with S-1 group and 54 cases in S-1 group.The efficacy and adverse reactions of the two groups were evaluated.Results The objective remission rate was 48.0％ (24/50) and 27.8％ (15/54) (x2=4.530,P =0.033),the disease control rate was 82.0％ (41/50) and 74.1％ (40/54) (x2=0.947,P=0.331),the median PFS was 6.6 months and 3.4 months (t=25.555,P =0.000),the median OS was 16.0 months and 10.5 months (t =59.439,P =0.000),respectively.The overall incidence of adverse reactions was 82.0％ (41/50) and 70.4％ (38/54) respectively (x2 =1.923,P=0.166),of which 18.0％ (9/50) and 13.0％ (7/54) were more than grade 3 respectively (x2 =0.506,P =0.477).There was no death caused by treatment-related adverse reactions in both groups.Conclusion Appatinib combined with S-1 capsule has good short-term and long-term efficacy in the treatment of advanced non-small cell lung cancer without gene mutation or unknown mutation.The adverse reactions are tolerable and can be used as first-line treatment for patients unwilling to receive intravenous chemotherapy.

Objective To analyze the efficiency of perinatal group B streptococcal(GBS)infection preven-tion in the local area.Methods From June 2015 to June 2016,3 667 pregnant women were included.Both pre-natal examinations and deliveries were done in our hospital.The analysis of GBS colonization,risk factors and prevention of early-onset disease were done.Results Among preterm and term pregnant women,the rates of GBS screening were 23.4% and 35.6%,respectively.The positive results of GBS were 10.9% and 8.4%,re-spectively.The percentage of women with 2 risk factors were 22.9% and 0.3%,respectively.GBS screening has a better prediction effect for GBS colonization status of women at labor.There were significant differences in the intrapartum antibiotic prophylaxis(IAP)implementation between preterm and term pregnant women. In the IAP efficiency analysis of preterm,GBS colonization and risk factors,preterm had a high sensitivity (96.1%),while the specialties of GBS carry and risk factors were high(93.2% and 90.3% respectively).Con-clusion preterm pregnant women should be highlighted as an important population in the implementation of IAP.GBS screening strategy is better than the risk factors strategy.
