Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective:To observe any effect of threshold pressure loaded inspiratory muscle training on the balance of persons with Parkinson′s disease (PD).Methods:Forty-eight persons with PD were randomly divided into an observation group and a control group, each of 24. Both groups were given conventional neurological drug treatment and conventional rehabilitation training. The observation group additionally completed inspiratory muscle training using a threshold pressure load trainer, 5 days per week for 8 weeks. Before and after the treatment, both groups′ inspiratory muscle functioning was quantified using ultrasound to assess diaphragm mobility and thickness, and maximum inspiratory pressure (MIP). Balance was quantified using Trunk Injury Scale (TIS) scoring, the Berg Balance Scale (BBS), limits of stability (LOS), and the timed up and go test (TUGT). Walking was evaluated using the 10-metre walk test (10MWT) and the Dynamic Gait Index (DGI).Results:After the treatment all of the indicators had improved significantly in both groups, on average, but those of the observation group were then significantly better. Correlation analysis showed that the difference in MIP of the observation group before and after treatment was significantly negatively correlated with the TUGT and 10MWT times.Conclusion:Threshold pressure loaded inspiratory muscle training combined with conventional rehabilitation therapy significantly improves the inspiratory muscle strength, balance and walking of persons with PD.

Obesity is increasingly prevalent globally, searching for therapeutic agents acting on adipose tissue is of great importance. Equisetin (EQST), a meroterpenoid isolated from a marine sponge-derived fungus, has been reported to display antibacterial and antiviral activities. Here, we revealed that EQST displayed anti-obesity effects acting on adipose tissue through inhibiting adipogenesis in vitro and attenuating HFD-induced obesity in mice, doing so without affecting food intake, blood pressure or heart rate. We demonstrated that EQST inhibited the enzyme activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), a therapeutic target of obesity in adipose tissue. Anti-obesity properties of EQST were all offset by applying excessive 11β-HSD1's substrates and 11β-HSD1 inhibition through knockdown in vitro or 11β-HSD1 knockout in vivo. In the 11β-HSD1 bypass model constructed by adding excess 11β-HSD1 products, EQST's anti-obesity effects disappeared. Furthermore, EQST directly bond to 11β-HSD1 protein and presented remarkable better intensity on 11β-HSD1 inhibition and better efficacy on anti-obesity than known 11β-HSD1 inhibitor. Therefore, EQST can be developed into anti-obesity candidate compound, and this study may provide more clues for developing higher effective 11β-HSD1 inhibitors.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.

Objective To prepare human alpha segment of high affinity IgE receptor(FcεRIα)protein by genetic engineering technology and to identify its biological function for laying the foundation for further researching the role of FcεRIα in allergic disea-ses.Methods The human FcεRIα gene was obtained by the PCR based accurate synthesis(PAS)method and the prokaryotic ex-pression vector pET-28a(+)was constructed.The FcεRIα was expressed at low temperature induction and the recombinant protein was purified by His tag.The biological function of recombinant human FcεRIα protein was identified by ELISA.Results The hu-man FcεRIα gene was amplified by PAS with a size of approximately 560 bp.The pET-FcεRIα plasmid was correct through the double enzyme digestion and sequencing identification.The human FcεRIα with a molecular weight of approximately 22 000 was in-duced and purified.The recombinant human FcεRIα could effectively detect human serum anti-FcεRIα autoantibody and could com-bined with serum IgE antibodies with high efficiency.Conclusion Human FcεRIα protein is successfully prepared,which prelimina-rily has the ability for detecting the human serum anti-FcεRIα autoantibodies and IgE antibodies,and provides a favorable practical base for further study.

Objective To explore the gait features under dual task walking and its relationship of fear of falling in elderly patients with type 2 diabetes.Methods A total of 168 elderly patients with type 2 diabetes were selected.Patients were asked to complete the general information questionnaire,mini-mental state examination and fear of falling assessment.The gait parameters under normal and dual task walking were measured objectively and quantitatively by IDEEA,and the relationship between fear of falling and the gait parameters under dual task walking were explored.Results Elderly patients with type 2 diabetes were more prone to gait abnormalities in dual task walking,and compared with those who are not fear of falling,the gait performance in dual task walking decreased significantly in the patients with fear of falling,such as lower velocity and step length,higher variability of stride time(all P＜0.05).Conclusion Elderly patients with type 2 diabetes were more prone to gait disorders in dual tasking than normal walking.Normal walking test may overestimate the actual walking ability of patients.In contrast,dual task walking test can better reflect the challenges of daily life,and be closer to the patient walking patterns in real life,which might be better suited for assessing actual mobility of patients.In addition,elderly patients with type 2 diabetes who are fear of falling are more prone to gait abnormalities in dual tasking walking.

Objective To explore gait features at usual speed of community-dwelling elderly people,and its relationship with history of falls in the past one year.Methods According to history of falls in the past one year,135elderly people in Hefei City were recruited and divided into fallers(23 cases) and non-fallers(112 cases).Self-designed questionnaires were completed by all participants to collect data including gender,age,frequency of exercise,BMI,Barthel Index,MMSE,fear of fall and so on.Gait parameters were measured by IDEEA LifeGait when participants walked for 10 meters at usual speed.Results Between fallers with non-fallers,the time of Timed Up and Go Test had statistically significant differences(P＜0.05).Gait analysis results showed that swing power,foot fall,preswing angle,speed had statistically significant differences between two groups (all P＜0.05).Conclusion When community-dwelling elderly people are walking at usual speed,the shorter of the time of Timed Up and Go Test,the weaker of swing power,foot fall and pre-swing angle and the slower speed is,the more possible falls will occur.

Objective To explore the effect of the solution-focused approach when applied in real cross-sectional assessment of young nurses. Methods Totally 136 young nurses who worked in Hai'an Affiliated Hospital of Nantong University for less than 3 years were selected by stratified sampling and random number table, and equally divided into an observation group and a control group between January and December 2015. Nurses in the control group were assessed through the real cross-sectional approach, while nurses in the observation group were not only assessed through the real cross-sectional approach, but also intervened through the solution-focused approach. Then the two groups were compared according to the results of the real cross-sectional assessment and Selfrating Anxiety Scale (SAS) before and after the intervention. Results Before the intervention, there was no statistical significance in the two groups' results of the real cross-sectional assessment and SAS (P>0.05); Psychologically intervened with the solution-focused approach, the observation group's score for the real cross-sectional assessment (82.044±2.195) was higher than that of the control group (75.573±4.536), and the observation group's SAS score (39.058±4.270) was lower than that of the control group (51.382±5.411) (t=10.588,14.742;P<0.05).Conclusions The solution-focused approach, when applied in real cross-sectional assessment of young nurses, helps to reduce nurses' mental pressure and anxiety and build up their confidence substantially, thus improving their real performance capability.

Objective To explore a more effective way to enhance the clinical efficacy of cluster immunotherapy for perennial allergic rhinitis. Methods A total of 60 perennial allergic rhinitis patients were evenly randomized into treatment goup and control group. The two groups were given cluster immunotherapy, and the treatment group was given daily vesiculating moxibustion additionally . Before and after treatment, the scores of traditional Chinese medical constitution and the rhinitis quality of life ( QOL) were observed, and one year after treatment, the therapeutic effect and safety were evaluated. Results ( 1) One year after treatment, the treatment group showed better total clinical efficiency than the control group ( 96.67% vs 80.00%, P<0.05). ( 2) After treatment, the average scores of Qi deficiency constitution, yang deficiency constitution and special constitution were significantly lower than those before treatment in the treatment group ( P<0.01). The improvement of Qi deficiency constitution and yang deficiency constitution in the treatment group was superior to that in the control group ( P<0.05). ( 3) The total QOL scores and the scores of each dimension of QOL scale were improved in both groups, and the differences were significant except for the emotion dimension ( P<0.01). Insignificant differences were shown between the two groups after treatment ( P>0.05). ( 4) Two cases had grade 1 general adverse reaction and 5 cases had local adverse reaction during cluster immunotherapy. During vesiculating moxibustion, 3 cases had blistering and the blistering disappeared after symptomatic treatment. Conclusion Daily vesiculating moxibustion combined with cluster immunity therapy is effective for the treatment of allergic rhinitis, showing good effect on improving Qi deficiency constitution, yang deficiency constitution and special constitution as well as the quality of life of the patients.
