Objective: To investigate the value of ultrasound guided intra-amniotic instillation of pulmonary surfactant (PS) combined with prenatal ambroxol hydrochloride (AH) for prevention of lung injury in preterm rabbits. Methods Totally 20 pregnant New Zealand rabbits were randomly divided into 4 groups (each n=5), i.e. ultrasound guided intra-amniotic instillation of PS before cesarean section (PS group), prenatal AH (AH group), ultrasound guided intra-amniotic instillation of PS combined with prenatal AH (PS+AH group) and control group. On the 27th day of pregnancy, rabbit fetuses were removed through cesarean section 1 hour after injection. The survival time of the preterm rabbits, the concentration of interleukin-6 (IL-6) and dipalmitoyl phosphatidylcholine (DPPC) in bronchoalveolar lavage fluid, the expression level of pulmonary surfactant-associated proteins-A (SP-A) in lung tissue were detected. And the lung tissue sections were taken to observe the degree of lung injury. Results: Compared with control group, the survival time of the preterm rabbits of PS group, AH group and PS+AH group prolonged, the concentration of IL-6 decreased, the concentration of DPPC and SP-A increased, and the pathological score of lung injury decreased (all P<0.05). There were significant differences between PS+AH group and PS, AH group in those indexes except for survival time (all P<0.05). Conclusion: Ultrasound guided intra-amniotic instillation of PS combined with prenatal AH plays a role in the prevention of lung injury in preterm rabbits.

Chronic kidney disease (CKD) is characterized by long course, poor prognosis, multiple complications and high cost of treatment, thus it has become a major public health problem. Based on review of publications pertaining to the epidemiological study of CKD from February 2002 to March 2023, this article summarizes the epidemiological characteristics, risk factors, prevention and control strategies of CKD. It is found that China has the largest number of adult patients with CKD in Asia, and the prevalence of CKD is higher among females and elderly people. The influencing factors for CKD include cardiovascular diseases, diabetes, hypertension and coronavirus disease 2019. Henceforth, it is of vital importance to emphasize three levels of prevention and optimize the CKD management, so as to support for prevention and control of CKD.

Abstract Falls are the leading cause of accidental injury deaths among the elderly. Currently, the incidence and disease burden of falls among the elderly remain high. By understanding the influencing factors of falls among the elderly and formulating targeted preventive measures, the risk of falls can be effectively reduced. Studies have found that falls among the elderly are results of the interaction of multiple factors. When formulating fall prevention strategies, attention should be paid to fall risk assessment and stratification, fall prevention exercise support and health education, living environment improvement, and primary healthcare service enhancement. Reviewing publications pertaining to the epidemiological studies of falls from January 2004 to January 2024, this article summarizes the epidemiological characteristics, risk factors, prevention and control strategies of falls among the elderly, aiming to provide the reference for prevention and control.

Objective To investigate if there were connections between sporadic Parkinson's disease (PD) and three single nucleotide polymorphisms (SNPs) in transmembrane protein 175 (TMEM175 rs34311866), methylcrotonoyl-coenzyme A carboxylase 1 ( MCCC1 rs12637471 ) and alpha-synuclein (SNCA rs356182) in Northern Chinese Han population , and provide basic data for PD genetic research. Methods The research recruited 310 sporadic PD patients in northern Chinese Han population from the Department of Neurology, the First Hospital of China Medical University between 2008 and 2012, and 339 controls without nervous system manifestations from other departments of the First Hospital of China Medical University during the same period.We applied cleaved amplification polymorphism sequence-tagged sites polymerase chain reaction-restriction fragment length polymorphism method to detect the genotype distributions of the SNPs in the northern Chinese Han population , and calculated relevance with PD of the SNPs by chi-square test.Results According to the data, the allele A of SNCA rs356182 had positive effects on the onset of PD in northern Chinese Han population compared with controls (patient group A%＝20.97%(130/620), control group A% ＝29.20%(198/678), χ2＝11.632, P＝0.001); allele G of MCCC1 rs12637471 (χ2＝0.009, P＝0.926) and allele C of TMEM175 rs34311866 (χ2＝1.369, P＝0.242) showed no significant differences between PD and control groups.Conclusion SNCA rs356182 was related with PD, and TMEM175 rs34311866 (M311Y) as well as MCCC1 rs12637471 showed no correlation with PD in the northern Chinese Han population.

Objective:To assess the age-related differences in the management strategies and outcomes of patients with acute coronary syndrome (ACS) under the chest pain center model.Methods:Clinical data of 2 833 patients with ACS were enrolled in the retrospective observational registry between January 2017 and June 2019 at 11 hospitals with chest pain centers in Chengdu. The patients were divided into four groups according to their ages: < 55 years old group ( n = 569), 55-64 years old group ( n = 556), 65-74 years old group ( n = 804), ≥ 75 years old group ( n = 904). The collected data included the patients' demographic characteristics, cardiovascular risk factors, medical history, symptoms and signs of onset, experimental examination, types of ACS and the time from the symptom to the hospital (S-to-D), etc., and the clinical characteristics, management strategies, all-cause mortality in the hospital, and the incidence of major adverse cardiovascular and cerebrovascular events (MACCE) within 1 year after discharge were compared. The primary end point was the clinical outcome of ACS patients in different age groups, including all-cause deaths in the hospital and the incidence of MACCE within 1 year after discharge. The secondary end point was the proportion of ACS patients underwent percutaneous coronary intervention (PCI) in different age groups. Multivariate Logistic regression was used to analyze the risk factors of all-cause deaths in ACS patients. Kaplan-Meier curve was used to express the incidence of MACCE within 1 year after discharge in different age groups. Multivariate Cox regression was used to analyze the factors affecting the incidence of MACCE within 1 year after discharge of ACS patients. Results:As age increased, the proportion of male patients gradually decreased, and the percentages of male patients aged < 55 years old, 55-64 years old, 65-74 years old, and ≥ 75 years old were 87.2% (496/569), 77.0% (428/556), 66.4% (534/804), and 60.1% (543/904), respectively; and ACS patients combined with hypertension, diabetes, coronary heart disease, and stroke history were more common [the percentages of patients with hypertension aged < 55 years old, 55-64 years old, 65-74 years old, ≥ 75 years old were 41.3% (235/569), 52.2% (290/556), 59.7% (480/804), and 66.9% (605/904); the percentages of diabetes were 18.6% (106/569), 25.5% (142/556), 27.0% (217/804), and 28.2% (255/904); the percentages of coronary heart disease were 10.1% (57/564), 13.9% (77/555), 17.6% (141/803), and 23.7% (213/899); the percentages of stroke were 0.7% (4/564), 4.0% (22/552), 4.5% (36/801), and 8.6% (77/894)]. But the percentages of patients with a history of active smoking, typical chest pain/chest tightness and dyslipidemia were significantly reduced [the percentages of smoking history were 60.2% (340/565), 48.0% (266/554), 33.7% (270/801), and 21.7% (195/899), typical chest pain/chest tightness were 96.9% (536/553), 96.4% (516/535), 91.8% (716/780), 90.2% (776/860); the percentages of dyslipidemia were 11.2% (63/565), 9.2% (51/553), 5.7% (46/802), and 4.9% (44/896)], the time of S-to-D was significantly prolonged [minutes: 176.0 (73.5, 557.0), 194.5 (89.3, 682.3), 221.0 (98.8, 940.5), and 270.0 (115.0, 867.0)], hemoglobin (Hb) level was significantly reduced(g/L: 145.44±17.43, 135.95±19.25, 129.75±19.03, 122.19±20.55), and the incidence of non-ST-segment elevation myocardial infarction (NSTEMI) increased significantly [18.6% (106/569), 20.5% (114/556), 26.6% (214/804), 26.5% (240/904)], and the differences were statistically significant (all P < 0.05). The proportion of Killip grade Ⅲ -Ⅳ were the highest in patients aged ≥ 75 years old, 9.0% and 12.6%, respectively. Compared with the groups aged < 55 years old, 55-64 years old, and 65-74 years old, the proportion of patients aged ≥ 75 years old who underwent PCI was the lowest, and the all-cause mortality in the hospital and the incidence of 1-year MACCE of patients underwent PCI were significantly lower than those of patients underwent conservative treatment [6.0% (28/463) vs. 10.4% (45/434), 14.6% (43/294) vs. 24.3 % (55/226), both P < 0.05]. As age increased, the hospital all-cause mortality and the 1-year MACCE incidence increased (all-cause mortality rates in < 55 years old, 55-64 years old, 65-74 years old, ≥ 75 years old groups were 0.9%, 2.2%, 5.5%, 8.3%, and the 1-year MACCE incidences were 5.0%, 6.7%, 13.9%, 18.7%, both P < 0.01). The multivariate Logistic regression analysis showed that age, cardiogenic shock, ST-segment elevation myocardial infarction (STEMI), the number of vascular disease and underwent PCI were the independent risk factors of all-cause mortality [the odds ratio ( OR) and 95% confidence interval (95% CI) were 1.644 (1.356-1.993), 11.794 (7.469-18.621), 2.449 (1.419-4.227), 1.334 (1.096-1.624), 0.391 (0.247-0.619), all P < 0.001]. Cox regression analysis showed that age, STEMI, the number of vascular disease and underwent PCI were independent risk factors of the occurrence of MACCE within 1 year after discharge [hazard ratio ( HR) and 95% CI were 1.354 (1.205-1.521), 1.387 (1.003-1.916), 1.314 (1.155-1.495), 0.547 (0.402-0.745), all P < 0.05]. Conclusions:In the chest pain center model, compared with other age of ACS patients, the proportion of NSTEMI in elderly patients group aged ≥ 75 years old was higher, the proportion of PCI was lower, and the clinical outcome was worse. However, the prognosis of elderly patients receiving PCI treatment was better than the patients receiving conservative treatment.

OBJECTIVEThis retrospective study is to analyze the outcomes of cN0 stage tongue squamous cell carcinoma and to discuss a reasonable neck management for these cases.

METHODSTotally 132 cases of cN0 stage tongue squamous cell carcinomas were included. Seventy-one cases were performed neck dissection(group ND), 61 cases were under wait-and-see (group WS). The clinical, pathological and follow up data of two groups were analyzed.

RESULTSThe cumulative three-year-survival between group ND and group WS were 87.3% and 83.4% respectively. In group ND, the survival of T1 and T2 cases were 89.3% and 83.3% respectively, while 89.6% and 58.3% in WS. For T2b cases which the size was larger than 3.0 cm, the survival of group WS was greatly lower than that of group ND. Both in ND and WS groups. The pathologically poor differentiation cases got poor survival than middle and well cases.

CONCLUSIONThe wait-and-see policy is recommanded for T1 stage cN0 tongue squamous cell carcinoma. For T2 cases that the tumor size is smaller than 3.0 cm, the wait-and-see is also reasonable, while the neck dissection should be considered in cases of poor differentiation. For large T2 cases, the selective neck dissection should be performed.

Insomnia is the second most common psychiatric disorder in clinical practice, and more than one-third of adults may experience different forms of insomnia during their lifetime, but the root causes behind insomnia need further clarification. Early evidences from twins and family studies had shown that insomnia can be attributed to genetics. In recent years, with the rapid development of gene sequencing technology, Nature Genetics had published several consecutive articles focusing on insomnia and genes, confirming that genetic factors played an important role in the occurrence and development of insomnia. Therefore, the recent research progresses on insomnia and circadian rhythm, cytokines, neurotransmitters, and other related genes were summarized in this review, which could help to understand the pathogenesis of insomnia and develop precise treatment strategies.
