Objective To study the breast augmentantion by a large amount of auto fat granule injection. Methods The author selected the fat patients who wanted both breast augmentation and liposection. Large amount of auto fat granule, the fat suspended solution, was obtained from patient's abdomen or buttocks and thighs. The fat suspended solution had been washed by normal saline solution repeatedly, in order to get rid of blood, serum and liquefied fat. Then the auto fat granule solution was injected into breast glands and their underneath and behind pectoral majority muscle. The quantity of fat suspended solution injected was 150～305 ml in each side of breast. Total of 21 cases had been performed by auto fat granule solution injection in our department from Oct.1997 to April 2001. Results Breast augmentation by auto fat granule solution injection were successful and positive, without any complications. The results were satisfied both from patients and surgeons. It showed that the contouring of breast were improved and more chubbiness than that before operation. Conclusions The auto fat granule injection for the breast augmentation is an effective and practical method. It can also be used to inject into the other parts of the body to fill in soft tissue defects.

ObjectiveTo investigate the prevalence of dental caries among preschool children in Chongming District， Shanghai， and to analyze the related factors influencing dental caries in preschool children in Chongming District， in order to provide references and suggestions for the prevention of dental caries in preschool children in Chongming District. MethodsFrom January to April 2022， 939 preschool children from 5 kindergartens in Chongming District of Shanghai were selected as the research objects through random cluster sampling. The dental caries prevalence rate and related risk factors of dental caries in preschool children were studied through oral examinations and questionnaire surveys. ResultsThe prevalence rate of dental caries among the 939 preschool children was 45.69%. The prevalence of dental caries in preschool children was not related to gender but increased with age （P<0.001）. Risk factors for dental caries in children included consuming desserts between meals or before bedtime （OR=3.049， P<0.001）， consuming sugared milk （OR=2.389， P=0.027）， presence of dental caries in caregivers （OR=1.888， P<0.001）， age （OR=1.758， P<0.001）， regular consumption of certain beverages by children （OR=1.250， P=0.029）， and the frequency of snack consumption （OR=1.191， P=0.034）. ConclusionTo reduce the incidence of dental caries in preschool children， it is recommended that caregivers undergo oral health examinations and dental caries treatment to reduce the transmission of cariogenic bacteria. Additionally， reducing the frequency of children’s consumption of snacks， sugary drinks， and dairy products， and avoiding unhealthy eating habits such as consuming desserts before bedtime are advised. It is also important to educate children on proper toothbrushing methods to ensure the effectiveness of toothbrushing and to encourage them to develop good oral hygiene habits.

ObjectiveTo study the epidemiological characteristics of deaths due to pneumoconiosis and its complications in order to improve the prevention and management of pneumoconiosis. MethodsThe pneumoconiosis deaths who died during 1959‒2019 in Chongming District of Shanghai were investigated and analyzed retrospectively by the descriptive epidemiological methods. The correlation of the age of onset and the course of disease was analyzed by Spearman rank correlation，as well as the duration of dust exposure and the course of disease in pneumoconiosis patients. ResultsFrom 1959 to 2019， there were 226 pneumoconiosis deaths， 223 males （98.67%）. The mortality of silicosis was the highest （82.07%）. The age of onset of pneumoconiosis was negatively correlated with the course of disease （r_s=-0.596，P<0.001）.There was no correlation between the duration of dust exposure and the course of disease in pneumoconiosis patients （r_s=-0.107，P=0.109）.There were statistically significant differences in mortality among groups in different types and stages of pneumoconiosis（χ²=59.250，27.666，both P<0.05）. The mortality increased with the increase of stage of pneumoconiosis. The mortality of pneumoconiosis was significantly different in 1959‒1979， 1980‒1989， 1990‒1999， 2000‒2009 and 2010‒2019 （χ²=29.750， P<0.05）. The top three causes of death in pneumoconiosis cases were respiratory diseases， malignant tumor and cardiovascular and cerebrovascular diseases.ConclusionIt is suggested to further strengthen the health monitoring and management of pneumoconiosis patients，control lung and chronic respiratory diseases to delay the life expectancy and improve quality of life of pneumoconiosis patients.

Objective To analyze the the incidence of sedation-related adverse events occurring during percutaneous microwave ablation(PMWA)under deep sedation,and to identify the risk factors for hypoxemia,hypertension and body movement response.Methods The clinical data of 506 patients with liver cancer,who received PMWA under deep sedation at the First Affiliated Hospital of Nanjing Medical University of China between December 2018 and December 2022,were retrospectively analyzed.The sedation-related adverse events including hypoxemia,hypertension and body movement response were recorded.Univariate analysis and multivariate logistic regression analysis were used to assess the risk factors for hypoxemia,hypertension and body movement response.Results After excluding 20 patients whose clinical data were incomplete,the final study sample consisted of 486 patients.After deep sedation,hypotension occurred in 5 patients(1％),and the incidences of hypoxemia,hypertension and body movement response were 13.8％,13.2％and 25.5％respectively.No patient required urgent endotracheal intubation and no cardiovascular complications occurred.The body movement response did not increase the complications of PMWA.Multivariate analysis revealed that age ≥65 years(OR=1.034,P=0.033),BMI＞30 kg/m2(OR=1.865,P=0.039),and Child-Pugh grade B/C(OR=1.113,P=0.046)were the risk factors for hypoxemia.The ablation zone contacting the parietal peritoneum(OR=2.536,P＜0.01),ablation zone contacting the diaphragm(OR=1.795,P=0.001),and ablation zone contacting the adrenal gland(OR=1.581,P＜0.01)were the risk factors for hypertension.The ablation zone contacted the parietal peritoneum(OR=2.831,P＜0.01)and ablation zone contacted the diaphragm(OR=2.213,P=0.026)were the risk factors for body movement response.Conclusion For the treatment of liver cancer,PMWA under deep sedation is clinically safe and effective.The age ≥ 65 years,BMI＞30kg/m2,and Child-Pugh grade B/C are the risk factors for hypoxemia.The ablation zone contacting the parietal peritoneum,the diaphragm or the adrenal gland are the risk factors for hypertension.The ablation zone contacting the parietal peritoneum or the diaphragm are the risk factors for body movement response.(J Intervent Radiol,2023,32:1202-1206)

Objective: To investigate the prevalence of metabolic syndrome in adults in Shanghai Chongming area and to analyze the relationship between metabolic syndrome and chronic kidney disease. Methods: A total of 7 679 residents aged 30 years and over in Chongming District of Shanghai were randomly sampled and investigated by questionnaires, physical examinations, and laboratory examinations. The metabolic syndrome was diagnosed by the diagnostic criteria of metabolic syndrome according to the Chinese Guidelines for the Prevention and Treatment of Type 2 Diabetes in 2017. According to the criteria of the International Society of Nephrology Working Group on Improving the Overall Prognosis of Kidney Diseases, estimated glomerular filration rate (eGFR)<60 ml·min^-1·(1.73 m²)^-1 was diagnosed as chronic kidney disease. Results: The prevalence of metabolic syndrome was 38.61% in the total population. The prevalence of metabolic syndrome was 47.06% in males and 34.71% in females. Urinary albumin-creatinine ratio (ACR), eGFR, age, smoking, waist circumference, blood glucose, blood pressure, high density lipoprotein-cholesterol and triglyceride in metabolic syndrome group were significantly higher than those in non- metabolic syndrome group. With the increase of metabolic components, eGFR decreased, and ACR increased. According to logistic regression analysis, age, male, hyperglycemia, hypertension, hypertriglyceride were risk factors for eGFR. Male, hypertension, hyperglycemia, hypertriglyceride, central obesity, smoking history, lower education level were risk factors for ACR. Conclusion The number of metabolic components is related to renal damage. Male, hypertension, hyperglycemia, hypertriglyceride are risk factors for early renal damage.

Objective To assess the psychometric potential of the Montreal Cognitive Assessment Scale-Beijing (MoCA-BJ) as a screening instrument for mild cognitive impairment (MCI) in older adults in Wuhan communities of central China. Methods MoCA-BJ and Mini-Mental State Examination (MMSE) were adopted to assess the MCI of 381 older adults from 13 communities in Wuhan in 2015. Confirmatory factor analysis was conducted to evaluate the construct validity of MoCA-BJ, and the relationship between all aspects of cognitive function and MoCA different dimensions. Results MoCA-BJ had acceptable reliability (w=0.76), and MoCA-BJ and MMSE estimation results were highly correlated (r=0.73, P＜0.01). By comparing three measurement models through confirmatory factor analysis, we found that the MoCA-BJ scale had two factors (F1: visual space executive function, F2: memory-based other cognitive functions) in model 3, fit degree of which was higher than model 1 by one factor, and there was a statistically significant difference in the number of factors between model 1 and model 3 (χ2dif=8.73,P＜0.01). Conclusions The MoCA-BJ has two underlying factors that respectively represent two highly correlated but distinct factors, cognition and visual-spatial. Uninformative items should be revised with culturally sensitive items and the cut-off point for mild impairment should also be altered.

Objective: To establish a novel stress-induced depression model by changing the lighting conditions and continuously damping cushion (L-D). Methods: The L-D stress depression animal model was established in C57BL / 6 mice with body weight of 18-22 g. Seventy-five mice with the horizontal and vertical scores higher than 30 and less than 120 in open field test were employed.In the research of model construction, mice were randomly divided into three groups: control group (n=9), chronic unpredictable mild stress(CUMS) model group (n=10) and L-D model group (n=9). In the drug intervention experiments, mice were randomly divided into five groups: control group (n=9), chronic unpredictable mild stress(CUMS) model group (n=10), L-D model group (n=9), CUMS+ fluoxetine group (n=10) and L-D model+ fluoxetine group (n=9). Open field test, forced swimming test and sucrose preference test were used to evaluate the degree of depression in animals. Results: (1) In the open field test, the horizontal score of CUMS model group (67.20±5.81) and the L-D model group (52.56±19.05) were significantly lower than that of the control group (76.44±9.22) (t=2.645, t=3.387, both P<0.05). And horizontal score of the L-D model was significantly lower than that of the CUMS model (t=2.321, both P<0.05). In forced swimming experiment, compared with the control group ((39.67±21.12)s), the immobility time of the CUMS model group ((60.90±10.34)s) and the L-D model group ((74.89±16.10)s) were significantly prolonged (t=2.831, 3.979, both P<0.05). The immobility time of the L-D model group was also significantly higher than that of the CUMS model group (t=2.278, P<0.05). In the sucrose preference experiment, the percentage of sucrose preference in CUMS model group ((72±7)%) and L-D model group ((65±5)%) was lower than that in the control group ((81±12)%) (t=2.195, 3.875, both P<0.05). The percentage of sucrose preference of L-D model group was significantly higher than that of CUMS model group (t=2.286, P<0.05). (2) After intervention with antidepressants, the horizontal scores of the CUMS model group (65.60±6.43) and the L-D model group (54.33±14.67) were significantly lower than that of the control group (75.78±8.27) in open field test (t=3.011, t=3.861, both P<0.05), and the score of L-D group was lower than that of CUMS group(t=2.235, P<0.05). The vertical score of the L-D model group (33.44±4.54) was significantly lower than that of the control group (39.22±5.56) (t=2.553, P<0.05). There was significant increase in the level score and vertical score of CUMS model and L-D model after fluoxetine intervention (t=3.090, t=2.692, both P<0.05), and significant twist in the vertical score of CUMS model and L-D model (t=2.681, t=2.354; both P<0.05). In the forced swimming experiment, the immobility time of the L-D model((64.11±13.06)s) was significantly longer than that of the control group ((42.00±13.77)s) (t=3.494, P<0.05). The immobility time of CUMS model and L-D model mice was significantly longer than that of non-intervention group (t=2.137, 2.940, both P<0.05). After the intervention of fluoxetine, there was no significant difference between the CUMS group, L-D group, the control group(all P>0.05). Conclusion Changing the lighting conditions and continuously damping cushion is a new method to establish mice model with depression behavior.Shorter modeling duration and simple operation are the main advantages of this model.

Metagenomic sequencing provides a powerful tool for microbial research. However, traditional experimental DNA extraction process will inevitably mix with environmental microorganisms which float in the air. It is still unclear whether the mixed environmental microbial DNA will heavily affect the metagenomic results of samples with extremely low microbial content. In this study, we first collected environmental bacteria in the laboratory and quantified the mixed environmental microbial DNA content during DNA extraction based on a qPCR-based quantification assay. We then extracted DNA from pure water in order to determine the mixed microbial taxons during extraction under open environment. At last, we extracted total DNA from a skin sample in a Biosafety cabinet or under open laboratory environment, to assess the impact of the mixed environmental microorganisms on the metagenomic results. Our results showed that DNA extraction under open laboratory environment in Beijing region resulted in 28.9 pg contaminant, which may accout for 30% of total DNA amount from skin samples. Metagenomic analysis revealed that the main incorporated environmental taxons were Cutibacterium acnes and Escherichia coli. Tens of environmental bacteria were foisted in the skin DNA samples, which largely decreased the relative abundance of dominant species and thus deteriorated the result accuracy. Therefore, analyzing microbial composition of samples with extremely low DNA content should better performed under aseptic environment.
