ABSTRACT
Objective:To observe the efficacy of self-help cognitive behavioral therapy for insomnia (CBTI), trazodone hydrochloride and their combination in the treatment of depression and insomnia comorbidity in the elderly.Methods:90 elderly patients with insomnia and depression admitted to the 901th Hospital of the Joint Logistic Support Force from October 2019 to October 2021 were selected as the study subjects. They were divided into trazodone group, CBTI group and trazodone combined with CBTI group(combination group), with 30 cases in each group. Trazodone group was treated with oral trazodone hydrochloride, CBTI group was treated with self-help CBTI, and the combination group was treated with oral trazodone hydrochloride combined with self-help CBTI. All three groups were treated for 4 weeks. The sleep latency, total sleep time and sleep efficiency of each group were compared at the time of admission and after 4 weeks of treatment. Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used for sleep assessment before and after treatment, and Self-Rating Depression Scale (SDS) was used for depression assessment.Results:Before treatment, there was no significant difference among the three groups in terms of sleep latency, total sleep time, sleep efficiency, PSQI, ESS and SDS (all P>0.05). After treatment, the sleep latency of the three groups was shorter than that before treatment, and the total sleep time was longer than that before treatment (all P<0.05). The sleep efficiency of the trazodone group and the combination group was higher than that before treatment, with statistically significant difference (both P<0.05). The indexes of the combined group were better than those of the trazodone group and the CBTI group (all P<0.05). The sleep latency of the trazodone group was shorter than that of the CBTI group, and the total sleep time was longer than that of the CBTI group (all P<0.05), with statistically significant difference (all P<0.05). After treatment, the PSQI, except for the SDS of CBTI group, the ESS and SDS of the three groups were lower than those before treatment (all P<0.05). The PSQI, ESS and SDS of the combined group were lower than those of the trazodone group and the CBTI group, and the ESS and SDS of the trazodone group were lower than those of the CBTI group, with statistically significant difference (all P<0.05). Conclusions:For the elderly patients with depression and insomnia, the combination of self-help CBTI and trazodone can not only improve insomnia but also relieve depression symptoms, and the effect is better than that of trazodone and self -help CBTI alone.
ABSTRACT
The beneficial effects of hypoxic preconditioning are abolished in the diabetes. The present study was designed to investigate the protective effects and mechanisms of repeated episodes of whole body hypoxic preconditioning (WBHP) in db/db mice. The protective effects of preconditioning were explored on diabetesinduced vascular dysfunction, cognitive impairment and ischemia-reperfusion (IR)-induced increase in myocardial injury. Sixteen-week old db/db (diabetic) and C57BL/6 (non-diabetic) mice were employed. There was a significant impairment in cognitive function (Morris Water Maze test), endothelial function (acetylcholineinduced relaxation in aortic rings) and a significant increase in IR-induced heart injury (Langendorff apparatus) in db/db mice. WBHP stimulus was given by exposing mice to four alternate cycles of low (8%) and normal air O2 for 10 min each. A single episode of WBHP failed to produce protection; however, two and three episodes of WBHP significantly produced beneficial effects on the heart, brain and blood vessels. There was a significant increase in the levels of brain-derived neurotrophic factor (BDNF) and nitric oxide (NO) in response to 3 episodes of WBHP. Moreover, pretreatment with the BDNF receptor, TrkB antagonist (ANA-12) and NO synthase inhibitor (LNAME) attenuated the protective effects imparted by three episodes of WBHP. These pharmacological agents abolished WBHP-induced restoration of p-GSK-3β/GSK-3β ratio and Nrf2 levels in IR-subjected hearts. It is concluded that repeated episodes of WHBP attenuate cognitive impairment, vascular dysfunction and enhancement in IRinduced myocardial injury in diabetic mice be due to increase in NO and BDNF levels that may eventually activate GSK-3β and Nrf2 signaling pathway to confer protection.

ABSTRACT
<p><b>OBJECTIVE</b>To understand the epidemiological profiles of hand, foot and mouth disease (HFMD) and the major enteroviruses causing the epidemics of HFMD in Shanghai from 2010 to 2014.</p><p><b>METHOD</b>The city-wide surveillance data between 2010 and 2014 were used to analyze the epidemiologic characteristics of the HFMD outbreaks in Shanghai. The annual incidence of HFMD was estimated based on the 2010 Shanghai Census data.</p><p><b>RESULT</b>From 2010 to 2014, the reported HFMD cases were 41 080, 37 323, 51 172, 42 198, and 65 018, respectively; the severe cases (case-severity ratio) were 469 (1.14%), 456 (1.22%), 318 (0.62%), 104 (0.25%) and 248 (0.38%), respectively. Based on Shanghai census data by the end of 2010, the attack rates of HFMD in Shanghai were 0.16%-0.28% in the entire population. In terms of the proportion of HFMD cases and severe cases in the specific population, male accounted for 59.62%-61.48% and 62.26%-73.08%, migrant population accounted for 51.86%-62.40% and 72.01%-80.38%; children aged 1.0-1.9 years comprised the highest proportion, up to 22.70%-27.00% and 32.08%-36.40%. HFMD peaked from April to July, in parallel with the peak circulation of enterovirus (EV) 71, and a small peak usually occurred in autumn and winter. All the critically severe and fatal cases were caused by EV71. The detection rates of EV71 and Coxsackievirus A (CA) 16 were 73.08%-88.09% and 1.12%-2.90% in severe HFMD cases, 19.75%-48.74% and 2.02%-23.69% in uncomplicated inpatients, and 16.78%-40.08% and 8.36%-33.39% in mild community cases, respectively. The detection rates of CA6 and CA10 in the mild community cases in 2014 were 18.38% and 1.43%, respectively. In 2013 non-EV71 and non-CA16 enteroviruses comprised 74.86% in the community cases.</p><p><b>CONCLUSION</b>The annual HFMD outbreaks occurred in Shanghai during 2010-2014. Children under 5 years of age, migrant population and male were the major susceptible population. EV71 and CA16 were the predominant pathogens causing the epidemics of HFMD except in 2013, and CA6 was prevalent in the community cases in 2014. The major peak season of HFMD usually overlapped with the peak of EV71 circulation and the majority of severe HFMD cases were associated with EV71 infection.</p>

Objective To investigate the pathotypes,epidemiological characteristics and antimicrobial resistance of diarrheagenic Escherichia coli (DEC) in children with acute bacterial diarrhea in Shanghai.Methods A total of 2 071 outpatient children with probable acute bacterial diarrhea referred to the enteric clinic of Children's Hospital of Fudan University during June 2012 to June 2014 were enrolled in our study.The stool samples were processed for routine microbiologic and biochemistry tests to identify enteric bacteria,including enteropathogenic Escherichia coli (EPEC),enterotoxigenic Escherichia coli (ETEC),enteroinvasive Escherichia coli (EIEC) and enterohemorrhagic Escherichia coli (EHEC).Kirby-Bauer method was used to identify the antibiotic sensitivity.Difference of means between groups was compared by chi-square test.Results Of 2 071 enrolled children,DEC were identified in 145 (7.0 ％)cases.148 strains were isolated with three of mix infection strains.All DEC isolates in this study included 106 (71.6％) EPEC,24 (16.2％) ETEC,16(10.8％) EIEC and 2(1.4％) EHEC.The median ages of diarrheal children with DEC infections were 14 months (range:3 months to 13 years) and 62.8％ of them were ＜2 years.Among 125 DEC isolates tested for antimicrobial susceptibility,the rates of resistance to ampicillin,trimethoprim-sulfamethoxazole,cefotaxime,cefepime,gentamicin,ceftazidime,amoxicillinclavulanate,ciprofloxacin,and ofloxacin in a descending order were 55.2％,35.2％,28.0％,27.2％,23.2％,8.8％,5.6％,4.0％ and 4.0％,respectively.Resistance rates of EIEC to cefotaxime,cefepime and ceftazidime were 50.0％,43.8％ and 25.0％,respectively,which were higher than those of EPEC,ETEC and EHEC.Conclusion DEC is the important enteric bacteria that causes bacterial diarrhea in children in this study.
ABSTRACT
Objective: To explore the correlation among serum prealbumin (PAB) level, red cell distribution width (RDW) and cardiac function in advanced aged male patients with chronic heart failure (CHF). Methods: Research objects included 60 patients with heart failure（28 cases with NYHA class Ⅱ and 32 cases with NYHA class Ⅲ-Ⅳ, heart failure group）and 30 cases with normal cardiac function admitted in the same period（normal control group）. Serum PAB, hemoglobin (Hb) concentration and RDW, red blood cell (RBC) count were measured. Patients all received echocardiography examination. Changes of all indexes were compared among patients with different cardiac function class. Results: ① Compared with normal control group, there was significant decrease in serum PAB level [(252±49) mg/L vs. (185±36) mg/L] and significant increase in RDW [(13.84±0.60) % vs. (15.79±1.33) %] in heart failure group, and compared with class Ⅱ group, there was significant decrease in serum level of PAB and significant increase in RDW in class Ⅲ-Ⅳ group, P<0.01 all; ② Compared with normal control group, there were significant decrease in E/A [(1.02±0.36) vs. (0.75±0.18)] and left ventricular ejection fraction [LVEF, (59±9) % vs. (49±11) %] in heart failure group, and the worse cardiac function was, the lower these two indexes were, P<0.01 all; ③ Pearson linear correlation regression analysis indicated that PAB was positively correlated with E/A and LVEF (r=0.451, P<0.05; r=0.596, P<0.05), and RDW was negatively correlated with E/A and LVEF (r=-0.391, P<0.05; r=-0.574, P<0.05) in heart failure group. Conclusion: Prealbumin and red cell distribution width are closely correlated to cardiac function class in advanced aged male patients. Both of them can indirectly reflect cardiac function in advanced aged patients with chronic heart failure.

ABSTRACT
ObjectiveTo understand the clinical epidemiology of enterovirus 71 (EV71) in children with hand,foot,and mouth disease (HFMD) in Shanghai during 2010 to 2011.Methods The demographic,etiological and clinical data of children with HFMD were analyzed retrospectively.EV71 was tested in stool samples by one-step quantitative reverse transcription-polymerase chain reaction (RT-PCR).The date were analyzed by Chi-square test.ResultsEV71 was detected in 820 (54.45％) of 1506 inpatients in 2010 and in 924 (59.84％) of 1544 inpatients in 2011,respectively.The detection rates in severe cases and uncomplicated cases were 86.31％ and 46.67％ (x2 =247.146,P＜0.01) in 2010 and 88.78％ and 48.75％ (x2 =201.664,P＜0.01) in 2011,respectively.The detection rate of EV71 was the highest (60％- 67 ％) during May and June when HFMD peaked.Among 1744 EV71-infected HFMD inpatients,the male-to-female ratio was 1.78 ∶ 1 ; the proportion of cases was the lowest in infant ＜6 months of age (0.46％,8/1744),and the highest in children 1 years of age (34.92％,609/1744); children aged 1-3 years accounted for 76.78％ (1339/1744);and migrant children accounted for 72.76 ％ (1269/1744).The demographic characteristics in severe cases were similar to those in general EV71-infected children.Nine severe cases of pulmonary edema/hemorrhage were all infected with EV71.Conclusions EV71 was a major pathogen causing the outbreaks of HFMD and severe complications in Shanghai in 2010 and 2011.Most severe cases and all critically severe cases were associated with EV71 infection.
