Alzheimer's disease(AD), a neurodegenerative disorder associated with aging, is the most prevalent form of dementia.As the aging population continues to expand, AD presents significant health and caregiving challenges for families and society, making it a pressing international public health concern.In recent years, numerous countries have implemented dementia prevention and treatment strategies that emphasize community-based comprehensive approaches.Currently, the community-based AD prevention and treatment model in China is still in the exploratory phase, with community efforts lacking organization.In alignment with China's action plan for advancing dementia prevention and treatment, and to achieve the strategic objective of "healthy aging, " this consensus is based on the principle of three-level prevention and is tailored to the characteristics of AD disease progression.It aims to develop a comprehensive prevention and treatment strategy for AD that is suitable for communities in China, providing technical guidance and support to establish a scientific basis for formulating community AD prevention and treatment models.

Objective:To observe and preliminarily analyze the risk factors related to silicone oil dependence after pars plana vitrectomy (PPV) in open globe injuries (OGI) .Methods:A retrospective clinical study. This study included 211 patients with OGI who received PPV treatment from January 1, 2005 to December 31, 2016 in Eye Injury Vitrectomy Study database. Silicone oil dependence was defined as the intraocular pressure <10 mm Hg (1 mm Hg= 0.133 kPa) in silicone oil tamponade eye 6 months after PPV. The patient's age, intraocular pressure, type of injury, length of eyeball wound, as well as the presence of ciliary body injury, choroidal injury, and retinal resection and/or defect area were recorded in detail. Logistic multifactorial regression analyzed the correlation between age, eye wound length and ciliary body iinjury, choroidal injury and retinal resection and/or defect severity and silicone oil dependence.Results:211 OGI eyes underwent vitrectomy were included, the mean age of the study population was 32.93 years (range 1-73 years), and the median follow-up period was 20.06 months (range 5.85-90.58 months). Among the 211 eyes, 121 (57.3%, 121/211), 52 (24.6%, 52/211), 23 (10.9%, 23/211) and 15 (7.1%, 15/211) were rupture, perforation, intraocular foreign bodies and penetrating injury, respectively. 98 eyes (46.4%, 98/211) of silicone oil dependence in total, among them, 64 (65.3%, 64/98), 19 (19.4%, 19/98), 9 (9.2%, 9/98) and 6 (6.1%, 6/98) eyes were rupture, perforation, intraocular foreign body and penetrating injury, respectively. Correlation analysis revealed that silicone oil dependence was significantly associated with ciliary body injury [odds ratio ( OR) = 2.150, 95% confidence interval ( CI) 1.052-4.393], choroidal injury ( OR=3.233, 95% CI 1.454-7.191), and retinal injury ( OR=2.731, 95% CI 1.393-5.353). No correlation was found with age ( OR= 0.981, 95% CI 0.960-1.002) or ocular wound length ( OR=1.716, 95% CI 0.987-2.984) ( P> 0.05). Conclusion:Silicone oil dependency following PPV in OGIs are associated with ciliary body, choroidal, and retinal injuries, but no association with age or length of the ocular wound.

Intellectual disability (ID) is a group of neurodevelopmental disorders with high heterogeneous in both genotypes and phenotypes and its definitive diagnosis is increasingly dependent ongenome-wide molecular diagnostics.Based on next generation sequencing(NGS), panel sequencing, whole exome sequencing (WES) and even whole genome sequencing are well applied to the molecular diagnosis of ID. Based on these, we recommend WES, especially trio-WES as the preferred detection method. NGS data analysis and reanalysis for ID have clinical significance for diagnosis, and can detect small scale variation and copy number variation in the genome reliably. Therefore, it has the potential to become the next recommended molecular diagnostic toolfor ID.

Increasing e-waste has become a major problem for global environment and public health. In the process of dismantling and recycling of disordered electronic waste, heavy metals such as lead and brominated flame retardants and organic substances are released into environmental media such as air, soil, dust and water, which is harmful to the health of local residents. Taking an e-waste dismantling area in Guangdong Province as an example, this paper reviews exposure levels of heavy metals and organic matters in e-waste recycling areas in China, as well as the health effects of local residents. Previous studies have found that e-waste recycling activities led to serious environmental pollution and high exposure levels of heavy metals and organic matters in local residents, which has a certain impact on the physiological functions of various human systems. The establishment of a centralized dismantling zone can effectively reduce the load level of various pollutants.

Objective:To explore the characteristics of attention during visual search tasks in adults with attention-deficit/hyperactivity disorder (ADHD).Methods:Totally 45 adult patients with ADHD who met the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV) and 44 healthy controls matched with age,gender and IQ were selected.The reaction time and accuracy rate of two groups were compared under visual search tasks of low and high visual working memory load.Results:The reaction time was longer in patients with ADHD than in the healthy controls in both low-load task [(823 ± 144) ms vs.(754 ± 123) ms,P ＜ 0.01] and highload task [(912 ± 163) ms vs.(851 ± 162) ms,P ＜ 0.01].Compared with the performance in low load task,the search reaction time was longer in high load task [ADHD group:(823 ± 144) ms vs.(912 ± 163) ms,P ＜ 0.01;control group:(754 ± 123) ms vs.(851 ± 162) ms,P ＜0.01] and the accuracy rate was lower during high load task than low load task[ADHD group:(95.9 ±4.3)％ vs.(91.2 ± 14.29)％;control group:(95.8 ± 4.2)％ vs.(94.4 ±4.9) ％,P ＜ 0.01] in both ADHD and control groups.Conclusion:The results suggest impairment in top-down attentional control in ADHD adults.When the visual working memory load is increasing,ADHD patients allocate more working memory resources on storing the target representation and less resources on visual attention,so the search efficiency may be influenced.

Objective To observe the clinical efficacy of the combination of western medicine with acupuncture for treatment of polycystic ovary syndrome (PCOS) of infertility.Methods Totally 120 PCOS patients were randomly divided into western medicine group and acupuncture group, 60 cases in each group. All patients took Diane-35, and with whom resistant to insulin were added with Metformin. At the meantime patients increased the amount of exercise with adjustment and control of everyday diet. After three periods, the western medicine group used the method of Clomifene Citrate with Chorionic Gonadotropin to help ovulation induction. The acupuncture group used the method of acupoint selection including invigorating spleen and kidney with adjusting qi and blood to promote ovulation. The level of FSH, LH, FINS, E2 and T of the two groups were observed before and after treatment.Results After treatment, the levels of T, FINS, LH and BMI in the two groups decreased, with statistical significance (P<0.05). The levels of T and BMI in the acupuncture group were lower than the western medicine group after the treatment, with statistical significance (P<0.05). The total efficiency, gestation number, number of high-quality follicle, and basal body temperature of acupuncture group were all higher than the western medicine group, with statistical significance (P<0.05).Conclusion The combination of western medicine with acupuncture for treatment of PCOS of infertility has confirmed efficacy.

Objective To establish the pediatric reference intervals for Troponin Ⅰ and Creatine kinase-MB (CK-MB).Methods Healthy children (223 boys and 162 girls) aged from 7 months to 12 years old were studied.Blood specimens were collected and centrifuged,all serum samples were kept refrigerated below-70 ℃.Troponin Ⅰ and CK-MB were measured on the UniCel DxI 800 immunoassay system (Beckman Coulter) on the same day.Nonparametric statistics was used to estimate the 99th percentile reference intervals.Results The children were divided into three groups (group A 128 cases; group B 128 cases;group C 129 cases) according to age.The upper reference limits for CK-MB were dependent of age,and the group A (7 months-1 years) was shown to be 13.41 μg/L,the group B (2-3 years) was shown to be 9.35 μg/L,the group C (4-12 years) was shown to be 5.48 μg/L.The upper reference limit for Troponin Ⅰ was independent of age or gender and shown to be 0.01 μg/L among 385 children.Conclusions Pediatric reference intervals for Troponin Ⅰ and CK-MB have been defined in healthy children at a relevant age group (7 months-12 years).It is effective for clinical diagnosis and treatment of myocardial damage for children by determining reference intervals for Troponin Ⅰ and CK-MB.

In this paper , 2280 strains of suspicious Shigella c culture were detected by the diagnostic typing phage set for Enterobacteriaceae, the routine identification of them were carried oat at the same time . The results showed that 100% of shigella cultures were lysed with 10~3RTD and 99.9% lysed with 1RTD of phage Sh. 12.3% of 65 non-shigeUa cultures agglutinating with typing serum of shigeUa was lysed with 10~3RTD, 4.6% lysed with 1RTD of phage Sh. The determination of lytic-pattern of 2215 shigella culture indicated that only 3 strains of Boyd 5 of lytic-pattern 3 were not reported in literature, the rest strains were consistent to fomer studies. The nonshigella cultures lysed by Sh 10~3RTD could be excluded with 1RTD and its lytic-pattern. 20 strains of Enteroinvasive Escherichia coli possessing shigeUa-related antigens could be differentiated by Sh 10~3RTD. 1RTD and its lytic-pattern.
