Objective To study the clinical efficacy of wrist-ankle acupuncture on post-traumatic stress disorder (PTSD) after work-related injury. Methods 62 patients were divided into observation group (n=30) and control group (n=32). The observation group accepted wrist-ankle acupuncture combined with Paroxetine, and the control group accepted Paroxetine only. They were assessed with Clinical Administered PTSD Scale (CAPS), Hamilton Depression Rating Scale for Depression (HAMD), and Hamilton Anxiety Scale (HAMA) before, 6 weeks and 12 weeks after treatment. Results The scores of CAPS, HAMD and HAMA reduced in both groups (P<0.01) after treatment, and the reduction rate was greater in the observation group than in the control group (P<0.05). Conclusion Wrist-ankle acupuncture may further relieve PTSD after work-related injury

Objective To explore the influence of individualized health education to asthma children on the quality of life of their parents.Methods One hundred and one parents of asthmatic children from 3 different communities were randomly assigned to the intervention group(n=52)and the control group(n=49).Follow-ups were performed by phone calls and the Children Asthma Health Education Brochures were distributed among them in the two groups,meanwhile the individualized health education was given to the intervention group.The paediatric asthma caregiver's quality of life questionnaire(PACQLQ)was used to assess the quality of life of two groups.Results One month after intervention,the scores of the intervention group on PACQLQ total score as well as its items of activity limitation and emotional function were significantly higher than the control group(P<0.001 for all).Conclusion The individualized health education to the asthmatic children can improve the quality of life of their parents.

Objective To investigate the life quality of parents of asthma children as well as the influencing factors? Method Totally 125 parents of children with asthma from three different communities in Guangzhou were involved in the survey by the Chinese Paediatric Asthma Caregiver’s Quality of Life Questionnaire (PACQLQ) and demographic questionnaire? Results The total score on PACQLQ was(4?34±1?03): the scores on dimentions of limited motion and affection were(4?29±1?55)and(4?36±0?89),respectively?The major factors influencing the life quality of their parents included the relationship with them and their disease course? Conclusions The life quality of their parents reaches the lowest level at the beginning of confirmed diagnosis of asthma? The health education should be performed right after confirmed diagnosis? During health education,their mental stress is worth our great attention?

Objective: To investigate the antiamnesic effect of pregnenolone sialic glycoside on memory impairment in mice. Methods: Pharmacological model of amnesia in mice was produced by scopolamine. Learning and memory was evaluated using water maze performance of mice. Results: Significant memory deficit was induced by scopolamine (4 mg/kg, ip). Pregnenolone sulfate (0.1 5 mg/kg, sc ) failed to affect the scopolamine induced memory deficit. Pregnenolone sialic glycoside (0.1 5 mg/kg, sc) attenuated the deficit, decreased the time of finding platform, the errors of entering non exit and swimming distance at a dose of 1 mg/kg ( P

The traditional primary culture methods of human normal epithelial cells have disadvantages of low activity of cultured cells,the low cultivated rate and complicated operation.To solve these problems,researchers made many studies on culture process of human normal primary epithelial cell.In this paper,we mainly introduce some methods used in separation and purification of human normal epithelial cells,such as tissue separation method,enzyme digestion separation method,mechanical brushing method,red blood cell lysis method,percoll layered medium density gradient separation method.We also review some methods used in the culture and subculture,including serum-free medium combined with low mass fraction serum culture method,mouse tail collagen coating method,and glass culture bottle combined with plastic culture dish culture method.The biological characteristics of human normal epithelial cells,the methods of immunocytochemical staining,trypan blue exclusion are described.Moreover,the factors affecting the aseptic operation,the conditions of the extracellular environment,the conditions of the extracellular environment during culture,the number of differential adhesion,and the selection and dosage of additives are summarized.

Acute kidney injury (AKI) and hepatorenal syndrome (HRS) are serious complications in patients with end-stage liver disease, with renal injury as the main manifestation. They are interrelated, but also different from each other. There are several types of AKI, i.e., prerenal AKI, intrarenal or intrinsic AKI, and post-renal AKI, and type 1 HRS is considered a special type of AKI. There are different therapies for different types of AKI. With the improvement in the diagnostic criteria for AKI and chronic kidney disease in recent years, the diagnostic criteria and classification of HRS have also been updated. As for pathogenesis, systemic inflammation caused by intestinal bacterial translocation is attracting more and more attention. HRS was considered functional renal injury in the past, but recent evidence suggests the existence of structural injury. Vasoconstrictor combined with albumin is the main therapeutic drug for HRS. This article reviews the diagnosis and treatment of AKI in end-stage liver disease and the recent advances in the diagnostic criteria, classification, pathology, pathogenesis, and treatment of HRS.

Objective:To study the efficacy of nasal intermittent positive pressure ventilation (NIPPV) and minimally invasive surfactant therapy (MIST) in very preterm infants with respiratory distress syndrome (RDS).Methods:From January to December 2020, very preterm infants (gestation age ≤30 weeks) with RDS born and treated in our hospital were randomly assigned into NIPPV group and nasal continuous positive airway pressure (NCPAP) group. Both groups were treated with MIST technique. The following items were compared between the two groups:adverse reactions during MIST, partial pressure of carbon dioxide (PaCO 2) at 2 h after MIST, the incidences of intubation within 72 h, two or more doses of pulmonary surfactant (PS), frequent apnea, other complications and the parameters of respiratory support treatment. Results:A total of 62 cases were included, with 32 in the NIPPV group and 30 in the NCPAP group. Compared with the NCPAP group, the NIPPV group had lower incidences of bradycardia (6.3% vs. 30.0%), decreased oxygen saturation (12.5% vs. 40.0%) and apnea (6.3% vs. 30.0%) during MIST ( P<0.05). No significant difference existed in the incidence of regurgitation ( P>0.05). PaCO 2 at 2 h after MIST [40.1(38.2,43.8)mmHg vs. 48.3(44.1,50.0)mmHg], the incidences of intubation within 72 h (6.3% vs. 30.0%), two or more doses of PS (6.3% vs. 30.0%)and frequent apnea (6.3% vs. 30.0%) in NIPPV group were lower than NCPAP group ( P<0.05). No significant differences existed between the two groups on the following items: the durations of invasive ventilation, non-invasive ventilation, oxygen therapy, the incidences of bronchopulmonary dysplasia, intraventricular hemorrhage (≥Ⅲ), periventricular leukomalacia, retinopathy of prematurity (≥Ⅱ), necrotizing enterocolitis (≥Ⅱb), nasal injury, air leak and death ( P>0.05). Conclusions:Combining NIPPV and MIST can reduce the incidence of adverse reactions during PS administration without increasing respiratory support duration and common complications in preterm infants. It is recommended for clinical use.
