Objective To examine the effect of modified electroconvulsive therapy (MECT) on the plasma oxida-tive stress level in bipolar depression. Methods Forty-two patients with bipolar depression were randomly divided into two groups. The intervention group (n=18) received antidepressants and 12 times MECT for 6 weeks and the control group (n=24) received antidepressants and Li2CO3 for 6 weeks. The Chinese versions of the 17 items Hamilton Depression Rating Scale (HAMD-17), Young Mania Rating Scale (YMRS), Clinical Global Impression Scale (CGI-S) and Treatment Emergent Symptom Scale (TESS) were used to assess participants at baseline and after 6 weeks of treatment. The plasma levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA)were detected at baseline and after 6 weeks to assess the level of oxidative stress. Results Repeated measures analysis of variance showed that the plasma level of SOD was higher in MECT group than in Li2CO3 group (F=15.26, P<0.01), and the level of MDA was higher in Li2CO3 group (F=18.18, P<0.01). The interactive effect of group and time was significant in GSH-Px level (F=6.39, P=0.02). The level of GSH-Px was lower in MECT group than in Li2CO3 group after 6 weeks (P<0.05). The CAT level was higher in the response patients than in non-response patients after 6 weeks (P<0.05). Con-clusions Both MECT treatment and Li2CO3 treatment can alter oxidative stress levels in patients with bipolar depression. The mechanisms underlying its therapeutic regimen may correct the imbalance of the plasma CAT level.

Intravenous leiomyomatosis (IVL) is a rare benign neoplasm which originates from the smooth muscle cells and is usually confined to the pelvic venous system. Rarely, intracaval and intracardiac extension has been described. Death can occur as a result of intracardiac involvement. We reported 4 cases of IVL with right heart involvement (intracardiac leiomyomatosis, ICL). Three of them suffered recurrent sudden syncope, and the other one was totally asymptomatic. All of them were successfully treated through one-stage operation under extracorporeal circulation.

Objective:To understand the output of research and education of clinical key Specialties in Henan Province, to analyze the current situation and existing problems, and to provide scientific evidence and suggestions for the improvement of specialist ability.Methods:Through the questionnaire survey to collect the scientific research data of key specialties from 2015 to 2019, apply Epidata 3.0 to input the data, use SPSS 21.0 software to carry out test and Mann Whitney U test, and carry out a comparative analysis of the national and provincial clinical key specialty discipline leaders, medical talent team, academic, scientific research and education output in Henan Province. Results:Academic literacy and scientific research ability of leaders of national and provincial key clinical specialties in Henan Province are equal. However, there is still a big gap in scientific research and education ability between national and provincial key clinical specialties in Henan Province.Conclusions:The provincial key clinical specialties need to improve the ability of scientific research and education in a more holistic way, further strengthen the medical talents team, and focus on the exchange of high-level academic platform and the cultivation of research talents.

OBJECTIVETo compare the clinical efficacy differences between acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method and traditional acupoint plaster therapy for senile osteoporosis (SOP).

METHODSWith randomized controlled blind design, 76 SOP patients with deficiency of liver and kidney syndrome were randomly divided into an observation group and a control group, 38 cases in each one. Based on oral administration of caltrate D, the patients in the observation group were treated with acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method at Yingu (KI 10), Taixi (KI 3), Dazhong (KI 4), Fuliu (KI 7) and Zhiyin (BL 67), while the patients in the control group were treated with traditional acupoint plaster therapy. Each plaster therapy lasted for 6 h, once a day; there was an interval of 2 d after consecutive 5-day treatment; 4 weeks were taken as one course, and totally 2 courses were given. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the pain and dysfunction before intervention, after 4 weeks and 8 weeks intervention. Osteoporosis symptom rating sale and quality of life questionnaire of the European foundation for Osteoporosis (QUALEFFO-41) were adopted to evaluate the TCM syndrome and quality of life before and after 8-week intervention.

RESULTSAll the outcomes were significantly improved after treatment in the two groups (<0.01,<0.05); after 4 weeks and 8 weeks of treatment, the VAS and ODI in the observation group were lower than those in the control group (all<0.05). Repeated ANOVA indicated the VAS and ODI were significant in group effect, time effect and interaction effect (all<0.01). Further comparison showed that VAS and ODI at later time points were lower than those in the early time points (all<0.01). After the treatment, the scores of TCM syndrome and QUALEFFO-41 in the observation group were lower than those in the control group (all<0.05). The effective rate was 85.7% (30/35) in the observation group, which was superior to the effective rate in the control group[74.3%(26/35),<0.05].

CONCLUSIONSThe acupoint plaster therapy with midnight-noon ebb-flow hour-prescription method is superior to traditional acupoint plaster therapy in improving pain, dysfunction, TCM syndrome and quality of life in SOP patients; in addition, its clinical efficacy is significant.
