Objective To analyze the mean flow in left internal m am mary artery ( L IMA) graft and the influencing factors in off- pump coronary artery bypass grafting ( OPCAB) in the Chinese. Methods One hundred and eighty patients with OPCAB were studied.Transit- tim e flowmeter( TTFM) was utilized to measure and record the L IMA’s blood flow wave,pulsatility index( PI) ,value of mean flow,systolic and diastolic peak flow,vascular resistance,insufficiency ratio and mean blood pressure and to analyze the relationship between mean flow of LIMA and other factors. Results Total mean flow calculated from that of all patients was2 8.19± 2 .89ml/ min( 6 - 178 ml/ m in) .Majority m ean value ( 6 4 .4 % ) was in the range of 10 - 30 ml/ min.Statistics showed that mean flow was significantly related to systolic and diastolic peak flow and vascular resistance rather than the other factors( r=0 .75 , 0 .94 ,- 0 .95 ) . Conclusions For the Chinese,over 10 ml/ min mean flow of L IMA graftis acceptable and ov...更多er 2 2 ml/ min is satisfactory.The diastolic peak flow and vascular resistance are two most important factors in influencing mean flow.
ObjectivesTo systematically review the current status of cognitive impairment of the elderly in China.MethodsCNKI, VIP, CBM, WanFang Data, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect studies on the current status of cognitive impairment of the elderly in China from January 1st, 2000 to March 12th, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using Stata 14.1 software.ResultsA total of 126 studies involving 187 115 elderly were included. The results of meta-analysis showed that the cognitive impairment rate of the elderly in China was 22.0% (95%CI 20.4% to 23.6%). Subgroup analysis showed that the cognitive impairment rate was higher in females, seniors, low education level, residing in rural area, engaging in manual labor, no spouse, living alone, monthly income less than 1 000 yuan, and suffering from chronic diseases.ConclusionsCurrent evidence shows that the cognitive impairment rate of the elderly in China is 22%, which is relatively high in females, seniors, low education level, residing in rural area, engaging in manual labor, no spouse, living alone, low-income, and suffering from chronic diseases.

Under the direct leadership of the Chinese Association Against Epilepsy (CAAE), the preparation of the “Training and examination syllabus of competency-based epilepsy education” was officially launched in March 2020. The Epilepsy Education Task Force of CAAE made reference mainly to the “Roadmap for a competency-based educational curriculum in epileptology” proposed by the report of the Epilepsy Education (EpiEd) Task Force of the International League Against Epilepsy, considered the actual situation of specialization in epilepsy at the different level hospitals in China, and finished the final draft after full discussion by the experts in relevant fields. The syllabus was divided into two parts: primary and intermediate level, in which a modular and layered design was adopted and the teaching requirements according to mastery, familiarity, and understanding were proposed. After the syllabus was finalized, it was used as a guideline in the subsequent online training and the primary and intermediate level examinations, which played an important role in cooperating with the smooth implementation of the “competency-based epilepsy education”.

Results The apparent effect of treatment group and control group were 30.6% and 42.4% of 42.4% of ITT. Results by Wilcoxon signed rank test indicated that there was a statistically significant difference. Conclusions Bi Yuan Shu Liquid may improve the effectiveness of sinus surgery, reduce the time course of antibiotics and hormones, and with out toxicity and side-effect.
ObjectiveTo assess effect of the self-made traditional Chinese medicine iontophoresis in treatment of acute lactation mastitis. MethodsTwo hundred cases of acute lactation mastitis who were treated in Langfang Maternal and Child Health-Care Hospital from Apr.to Nov.in 2012 were divided into traditional Chinese medicine group and control group by number of cases, each group enrolled 100 cases.The cases of traditional Chinese medicine group were treated with traditional Chinese medicine iontophoresis by using photoelectric ion therapeutic apparatus, and cases of control group were treated with 0.9% saline iontophoresis by using the same device.All of the 200 cases were treated with 1-3 courses (5 days per course), 2 times per day, and every time needed 30 minutes.At the same time, cases were educated the breast-feeding knowledge.Effect evaluation was performed after 1 course and 3 courses of treatment.The cases who were not cured after 3 courses needed to weaning, and needed to receive abscess incision drainage surgery.In 3 months after stopping therapy, telephone interview was performed to investigate the situation of recurrence. ResultsAfter 1 course of treatment, the effect was as follows:recovery in 89 cases, effective in 6 cases, invalid in 5 cases, and the total effective rate was 89%(89/100) in traditional Chinese medicine group; recovery in 71 cases, effective in 16 cases, invalid in 13 cases, and the total effective rate was 87%(87/100) in control group.After 3 courses of treatment, the effect was as follows:recovery in 97 cases, invalid in 3 cases, and the total effective rate was 97%(97/100) in traditional Chinese medicine group; recovery in 86 cases, invalid in 14 cases, and the total effective rate was 86%(86/100) in control group.There were 3 cases and 14 cases underwent abscess incision drainage surgery in Chinese medicine group and control group respectively.The clinical effect of Chinese medicine group were better than that of control group in 1 course (χ2=3.96, P < 0.05) and 3 courses (χ2=7.78, P < 0.01) of treatment.The recurrence rate of Chinese medicine group and control group were 5%(5/100) and 35%(35/100) respectively, and the rate of control group was higher (χ2=28.13, P < 0.01). ConclusionsCom-pared with 0.9% saline iontophoresis, the effect of traditional Chinese medicine iontophoresis in the treatment of acute lactation mastitis is better, which contribute to the breastfeeding.In addition, it is worth popularizing for that it can reduce the operation rate and recurrence rate effectively.
OBJECTIVE: In the guinea pig-to-rat cardiac xenotransplantation model, the effect of complement depletion by using Chinese Cobra Venom Factor(CVF) on hyperacute rejection was evaluated. METHODS: Cardiac xenograft from guinea pig was transplanted into the abdomen of rat after the recipient being given i.p. a dose of CVF 0.20 microgram/g. the recipients were divided into group A (control group), group B (only given CVF), group C (CVF + Cytoxan + Splenectomy), group D (Cytoxan + Splenectomy) Cytoxan was injected into the abdominal cavity with a dose of 60 mg/Kg. The survival time of xenograft was measured and histologic observation was carried out after the cardiac arrest. RESULTS: The survival time of xenograft ranged from 15 to 3,120 minutes. There were significant difference among group A compared with group B and C (P lt; 0.01), and no difference between group A and group D, as well as group B and C (P gt; 0.05). There were significant difference between group B and D, as well as group C and D(P lt; 0.01). The histologic observation proved that the hyperacute rejection in group A and D was milder than group B and C. CONCLUSION: The study reveals that CVF can prolong the xenograft time by depleting complement activities and restricting hyperacute rejection in this model. Further basic and clinical study of effect of CVF in xenograft transplantation is worthwhile.
