Scoping review of application effects of self-help intervention model in adult patients with depression / 中国实用护理杂志

Objective:To review relevant research on the application of self-help intervention model in adult depression patients, analyze the main characteristics and application effects of self-help intervention model, in order to provide reference for related research in this field.Methods:According to the methodological framework of the scope review, searched 12 Chinese and English databases including CNKI, Wanfang, PubMed, Web of Science, etc. from the establishment of the database until April 20, 2021, and sorted and analyzed the obtained documents according to the inclusion and exclusion standards.Results:A total of 45 documents were included, of which only 5 were from China; the included studies were mainly based on the Internet platform, using cognitive behavioral therapy, reading therapy, acceptance and commitment therapy, and problem-solving therapy for intervention; the duration of the intervention was 3 weeks to 4 months, participants complete an intervention module or read a specified number of chapters every 3 to 7 days on average, and receive regular guidance and supervision from the intervention facilitator every 1-2 weeks. The total contact time with the facilitator was 80-160 minutes. Various modes of self-help intervention based on the Internet could effectively improve the negative emotions of patients with depression.Conclusions:The self-help intervention model has shown good results in the treatment of patients with depression, but there is a lack of local intervention research in China, and there is no clear standard for the number of interventions and the length of the intervention guide. Under the general trend of "Internet + medical health", it is necessary to actively construct a self-help intervention model for depression with Chinese cultural characteristics, and form a systematic and standardized intervention strategy to address the many obstacles in time, location, resources and cost of people with depression, and finally achieve the purpose of improving the patients′ depressive symptoms and helping them to restore their social functions.

Factors influencing of the clinical outcome of interventional therapy for complex high-risk indicated coronary artery disease assisted by extracorporeal membrane oxygenation / 中华急诊医学杂志

Objective:To explore the factors influencing the clinical outcome of complex high-risk indicated patients percutaneous coronary intervention (CHIP-PCI) assisted by extracorporeal membrane oxygenation (ECMO).Methods:The clinical data of patients with CHIP-PCI assisted by ECMO in the First Affiliated Hospital of Zhengzhou University from April 2018 to April 2022 were retrospectively collected and analyzed. Patients were divided into the survival and death groups according to the in-hospital survival status. The baseline characteristic, the results of coronary angiography, and the use of ECMO, blood products and drug were compared between the two groups. The 24-h rate of change of biochemical test indicators after the use of ECMO were calculated and the univariate analysis was analyzed using rank sum test. According to the univariate analysis, the variables ( P<0.05) were included in multivariate logistic regression to analyze the factors affecting the clinical outcomes of patients. Results:A total of 67 CHIP patients who completed PCI with ECMO were included. In the survival group ( n=36), the duration of ECMO treatment was 59 (41, 87) h, 9 cases received continuous renal replacement therapy, and 11 cases received IABP. In the death group ( n=31), the duration of ECMO treatment was 31 (19, 80) h, 12 cases received continuous renal replacement therapy and10 cases received IABP. The proportion of patients with chronic total occlusion lesions (CTOs) in the survival group was lower than that in the death group, the duration of ECMO of the survival group was longer than that of the death group ( P<0.05). Multivariate logistic regression analysis showed that 24-h lactate change rate ( OR=2.864, 95% CI: 1.185-6.918, P=0.019), 24-h eGFR change rate ( OR=0.050, 95% CI: 0.003-0.871, P=0.040), 24-h D-dimer change rate ( OR=1.497, 95% CI: 1.044-2.146, P=0.028) and 24-h direct bilirubin change rate ( OR=2.617, 95% CI: 1.121-6.111, P=0.026) were associated with in-hospital mortality. Conclusions:Within 24 h after CHIP-PCI assisted by ECMO, the rapid decline in lactic acid, D-dimer and direct bilirubin, and the rapid recovery of eGFR, are associated with the decreased risk of hospital mortality from CHIP.

Objective:To determine the clinical efficacy and safety of a fractional CO 2 laser and a 1 064 nm, Q-switched Nd∶YAG laser therapy in the treatment of xanthelasma palpebrarum. Methods:From October 2020 to October 2021, 30 patients (5 males and 25 females) with bilateralxanthelasma palpebrarum of the eyelid were enrolled in the Department of Dermatology, the First Affiliated Hospital of Xiamen University. The age ranged from 38 to 67 (51±7) years. One side was randomly treated with fractional CO 2 laser as the fractional group, and the other side was treated with Q-switch 1 064 nm Nd∶YAG laser as the Q-switch group. The treatment was given every 28 days for 4 times. Before treatment and 1 month after the last treatment, the general pictures were taken to compare the clinical effect. Skin ultrasound was used to measure the difference of tumor thickness before and after treatment. The incidence of adverse reactions, such as local scar, hyperpigmentation or hypopigmentation after inflammation, were recorded. Results:Under general photos, there was statistically significant difference in efficacy scores between the two groups before and after treatment ( Z=-3.082, P<0.05). By comparison of tumor thickness under skin ultrasound, the difference between the two groups before and after treatment was statistically significant ( t=21.60, P<0.05; t=17.29, P<0.05); there was no statistically significant difference between the two groups before treatment ( t=0.46, P=0.650), but there was statistically significant difference between the two groups after treatment ( t=8.41, P<0.001). No serious adverse reactions occurred in both groups. Conclusions:Fractional CO 2 laser or Q-switch 1 064 nm Nd∶YAG laser can safely and effectively improve xanthelasma palpebrarum, in which the effect of fractional CO 2 laser is much better.

Objective:To study the safety of different peripherally inserted central catheter (PICC) dressing replacement frequencies in preterm infants.Method:From June 2017 to February 2020, preterm infants were enrolled in this prospective randomized controlled study. Preterm infants with PICC were randomly assigned into 7 d, 11 d and 14 d dressing replacement groups using online randomization software. Polyurethane transparent dressing and the same dressing replacement method were used in all three groups. The incidences of catheter-related bloodstream infection (CRBSI) and positive skin bacterial culture at dressing site were compared among the three groups.Result:A total of 296 cases were enrolled, including 96 cases in the 7 d group, 108 cases in the 11 d group and 92 cases in the 14 d group. The incidences of CRBSI in three groups were 2.5/1 000 catheter day in 7 d group, 1.1/1 000 catheter day in 11 d group and 0.8/1 000 catheter day in 14 d group. The incidences of catheter pathogen colonization were 1.0% in 7 d group, 0.9% in 11 d group and 0% in 14 d group. The positive rates of skin bacterial culture at dressing site were 1.0% in 7 d group, 2.8% in 11d group and 2.2% in 14 d group. The incidences of PICC exit site infection in three groups were 1.0% in 7 d group, 0.9% in 11d group and 1.1% in 14 d group and no significant differences existed among the groups ( P>0.05). Gram-positive cocci were the main bacteria [91.7% (11/12)] of CRBSI and skin bacterial culture at dressing site and gram negative bacilli accounted for 8.3% (1/12). No fungal infection were found. Conclusion:It is safe to replace the PICC dressing in premature infants as needed within 14 days if the dressing is intact without curling, bleeding and exudation.

Research on the awareness of disaster prevention and the ability of self-rescue and mutual aid among children in Mianyang Area / 中国小儿急救医学

Objective:To investigate the current situation of children′s awareness of disaster prevention and self-rescue ability in Mianyang area, provide reference for the development of scientific training programs on children′s disaster knowledge, and improve children′s survival ability during the disaster occurence.Methods:Through literature review and expert consultation, the questionnaire was designed by ourselves.Multi-stage sampling method was used to investigate 2 162 cases from county (city) high school, junior high school and primary school in Mianyang area.Results:8.3% of children had weak disaster awareness.Children had a good understanding of disaster related knowledge, with the highest alarm call awareness rate of 91.8%, fire, flood, earthquake escape and earthquake warning score of 86.5%, 84.2%, 84.2%, 83.0%.Cardiopulmonary resuscitation and fire hydrant operation awareness rate was very low (58.8%, 57.4%). Even some children still chose improper escape behavior.The scores of early warning knowledge and first aid skill were correlated with gender and age.In knowledge of disaster precursors, using of fire extinguishers and hydrants, and first aid skills, the scores of boys were significantly higher than those of girls ( P<0.001). Except for fire-related knowledge, gas leakage escape and shelter awareness rate, the older the children were, the higher the scores were ( P<0.05). The scores of early warning, escape knowledge and first aid skills were correlated with the location of home, and the differences were significant ( P>0.001). More than 80.0% of children chose flashlights, food and water, and emergency kits, while 65.0% to 75.0% children thought it was not necessary to prepare a radio, telephone directory, and cash. Conclusion:Children′s awareness of disaster reduction and self-rescue ability are generally good, but there are still insufficient first-aid skills and improper choice of escape behavior.The education of disaster awareness and self-rescue ability should be strengthened in children′s basic education so as to reduce the casualties of children caused by disasters.

Research on Optimization of Drug Supervision Strategy of Guangdong-Hong Kong-Macao Greater Bay Area Based on Tripartite Evolutionary Game / 中国药房

OBJECTIVE：To provide reference for improving the mechanism of drug supervision in Guangdong-Hong Kong-Macao Greater Bay Area. METHODS ：Based on the evolutionary game theory ，the stakeholders of Guangdong-Hong Kong-Macao Greater Bay Area in the stage of drug safety supervision were identified ；the evolutionary game model was established so as to obtain the behavioral selection and evolutionary stability strategy of the each party through and put forward the suggestions for improving the mechanism of drug supervision in Guangdong-Hong Kong-Macao Greater Bay Area. RESULTS & CONCLUSIONS：Based on evolutionary game theory ，the three-party evolutionary game model of drug administration ，drug inspection and manufacturing enterprises was established. According to the model established in this study ，it could be concluded that：when the compliance cost of the production enterprise was less than the sum of the violation cost and the bribery cost minus the additional income ，or less than the sum of violation cost and punishment and reputation lossminus the additional income ，the manufacturing enterprises could achieve the equilibrium state of compliance production ；the supervision probability was inversely proportional to the supervision cost ，and strict inspection was inversely proportional to inspection cost ；compliance productivity rate and strict detection rate were in direct proportion to the intensity of supervision and penalties ；the higher the supervision probability was，the higher the strict detection rate was ，and the compliance productivity would gradually increase. It is proposed to link enterprise information files ，lay the foundation of four party cogovernance ；introduce the “cost-benefit”supervision system ，make reasonable use of the third-party inspection institutions ；clarify the boundary of personnel responsibility ，and use the intelligent system for real-time supervision so as to promote the improvement of drug safety supervision in Guangdong-Hong Kong-Macao Greater Ba y Area.

Enhancement of Aggression Induced by Isolation Rearing is Associated with a Lack of Central Serotonin / 神经科学通报·英文版

Isolation rearing (IR) enhances aggressive behavior, and the central serotonin (5-hydroxytryptamine, 5-HT) system has been linked to IR-induced aggression. However, whether the alteration of central serotonin is the cause or consequence of enhanced aggression is still unknown. In the present study, using mice deficient in central serotonin Tph2 and Lmx1b, we examined the association between central serotonin and aggression with or without social isolation. We demonstrated that central serotonergic neurons are critical for the enhanced aggression after IR. 5-HT depletion in wild-type mice increased aggression. On the other hand, application of 5-HT in Lmx1b mice inhibited the enhancement of aggression under social isolation conditions. Dopamine was downregulated in Lmx1b mice. Similar to 5-HT, L-DOPA decreased aggression in Lmx1b mice. Our results link the serotoninergic system directly to aggression and this may have clinical implications for aggression-related human conditions.

Effect of partial neuromuscular blockade on efficacy and safety of nerve monitoring during microvascular decompression of facial nerve / 中华麻醉学杂志

Objective To evaluate the effect of partial neuromuscular blockade (NMB) on the efficacy and safety of nerve monitoring during microvascular decompression (MVD) of facial nerve.Methods Seventy American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 39-78 yr,weighing 44-84 kg,scheduled for elective MVD,were divided into 2 groups (n=35 each) using a random number table method:control group and partial NMB group.Anesthesia was induced by intravenous injection of 3-fold ED95 cisatracurium.In control group,muscle relaxants were not used after intubation.In partial NMB group,cisatracurium was continuously infused intravenously to maintain partial NMB,and the T1/Tc ratio was maintained at 20％-40％.Intraoperative neuroelectrophysiological monitoring was performed using lateral spread response (LSR).The success rates of LSR monitoring,occurrence of body movement,requirement for anesthetics and cardiovascular agents were recorded during operation,and the patients were followed up on day 7 after surgery,and the therapeutic efficacy and occurrence of neurological complications were recorded.Results Compared with control group,the incidence of intraoperative body movement was significantly decreased,the intraoperative consumption of propofol and remifentanil was decreased,and the intraoperative requirement for vasopressors was decreased in partial NMB group (P＜0.05).There was no significant difference in the success rate of LSR monitoring,therapeutic efficacy and incidence of neurological complications between two groups (P＞0.05).Conclusion Partial NMB (T1/Tc=20％-40％) can be effectively used for MVD monitored by LSR,decrease the occurrence of the body movement,and raise the perioperative safety in patients.
