Objective To evaluate the efficacy and safety of lentinan injection plus cisplatin (LIC) in the treatment of malignant pleural effusion (MPE).Methods We searched the database of Cochrane Library,PubMed,EMBASE,ISI Web of Knowledge,Chinese Biomedical Literature Database,Chinese Scientific Journals Full-text Database,Chinese Journal Full-text,and Google Scholar,etc.,up to February 28th,2011 to identify randomized controlled trials (RCTs) about lentinan injection (LI) for MPE,evaluate the quality of the included studies,and analyze the data by Cochrane Collaboration's RevMan5.0 software.Results Twenty-nine RCTs involving 1831 patients were included.Meta analysis results suggested that there were some differences when comparing LIC with control groups suffering from MPE,for LIC could improve the near-term curative effect and the quality of life to some extent.Besides,compared with chemotherapy alone,LI plus chemotherapy had an advantage in relieving adverse reactions,such as gastrointestinal reactions,myelosuppression,chest pain,and general malaise.Conclusion The current evidence indicates that LI may have adjuvant therapeutic effects for MPE.

A comparison teaching experiment was carried out in grade 2001 and grade 2002.The students majoring in clinical medicine in these two grades were taught surgery with graphical approach and traditional method respectively.The student number,the test marks and the survey by questionnaire show that graphical teaching approach is more attractive with its visualization and originality it can stimulate students' interests in learning,develop their thinking and improve their clinical analytic ability.It is an important approach to improve clinical teaching quality to lay a good foundation for students before their clinical practice.

The structure, karyotype and behavior of synaptonemal complex (SC) in the spermatocytes of hedgehog (Erinaceus euroaaus dealbatus (insectivora)) were analyzed by light and electron microscopy with a modified surface spread preparation which involves the use of sodium dodecyl-sulphate (SDS) and silver staining. The lateral elements of the synaptonemal complex have a constant width of about 50 nm, the distance between the two lateral elements is about 100 nm. The relative length and arm rationale constant for each autosomal SC. The relative length and arm ratio constant for ea of the autosomal SCs are very similar to that of mitotic autosome.The X and Y chromosome axes have a clear morphological distinction from the autosomal SC. The axes of X and Y chromosome pair and form a SC of certain length at pachytene stage. The axes of unpaired X and Y chromosome are heteropycnotic and display various morphological complexities. But these differentiations in hedgehog are primary than in other mammalians, such as human and mice. At pachytene stage the X and Y chromosome display an extensive side-by-side pairing segment with decreasing length as meiotic prophase progressed.

Objective To investigate the the treatment of class Ⅲ malocclusion by orthognathic surgery combined with postoperative orthodontics.Methods Nine patients with skeletal class Ⅲ malocclusion were treated by surgery-first approach without pre-surgical orthodontic from January 2012 to August 2014.The studied sample consisted of 7 women and 2 men (aged 15-28 years old, mean age 19.7 years), who had obvious mandibular protrusion.2 to 3 days after surgery, intermaxillary traction was used to made the maxilla and mandible together by board;we replaced a rubber band every 2 to 3 days and lasted for four weeks.We would dismantle board and performed conventional orthodontic treatment after patient's facial swelling subsided, and the positional relationship between the jaw stabilized.Results The face type of 9 patients were greatly improved after orthodontic treatment for 6.5 to 19.5 months.Patients and their family members felt satisfied, and their occlusal function returned to normal.At 3 to 32 months follow-up, the postoperative appearance and occlusion were becoming good without obvious signs of recurrence.Conclusions The surgery-first approach is an effective method to treat skeletal class Ⅲ malocclusion.

OBJECTIVE:To investigate the utilization of aspirin in patients with type 2 diabetes mellitus.METHODS:The utilization of aspirin in 510 inpatients with type 2 diabetes mellitus in the department of Endocrinology in our hospital from April 2004 to April 2007 was analyzed retrospectively.RESULTS:Of the total 510 cases,68.2% received aspirin,with daily dose reached 50～100mg.Aspirin was more often used in patients complicated with coronary heart disease and hypertension(P

OBJECTIVETo study the efficacy and safety of brucea javanica oil emulsion (BJOE) combining platinum-contained first-line chemotherapy in treating non small cell lung cancer (NSCLC).

METHODCochrane library, PubMed, EMBASE, VIP, CBM and CNKI were searched through computers. The search was finished in February, 2011. Randomized controlled trials (RCTs) of BJOE combining platinum-contained first-line chemotherapy were included. Two researchers extracted data and assess literature quality separately,and made a meta-analyses by RevMan 5.1.2 software.

RESULTTotally 22 RCTs involving 1512 patients were included. The Meta-analysis showed that compared with the pure application of platinum-contained first-line chemotherapy,the combination of BJOE and chemotherapy can enhance the near-term curative effect (RR = 1. 31, 95% CI: 1.18-1.45, P < 0. 000 01), improve the quality of life (RR = 1.78, 95% CI: 1.51-2. 09, P < 0.00001) and reduce the suppression of bone marrow (OR = 0.37, 95% CI: 0. 27-0. 51, P < 0.00001) and the gastrointestinal reactions (OR = 0.59, 95% CI: 0.44-0.80, P = 0.0007) ,with an improvement in organism immunity.

CONCLUSIONThe current evidence indicates that BJOE can enhance the chemotherapeutic effect on NSCLC patients, improve the quality of life and reduce adverse effect of platinum-contained chemotherapeutics and thus it is worth referring in clinic.

Objective:Using bibliometrics to study the international literature on fat transplantation in recent 10 years, and to explore the research status, hot spots and development trend in this field.Methods:Literatures related to fat transplantation research from 2011 to 2020 were searched through the core collection of Web of Science database, and the literatures were screened strictly according to inclusion and exclusion criteria. Statistical analysis was conducted on the year, journal, first author, number of articles published by countries and institutions, and distribution of disciplines by bibliometrics. Citespace5.7.R5W software was used for co-citation analysis of the included literatures. Cooccurrence analysis and emergent word analysis were also carried out on the keywords in the literature. VOSviewer1.6.16 software was used to perform visual clustering of terms in the title and abstract of the included literature to reveal hot topics and research frontiers.Results:A total of 4 901 papers were included, and the number of annual publications continued to increase from 2011 to 2020. The top three publications during the study period were Plastic and Reconstructive Surgery (320 papers), Aesthetic Surgery Journal (171 papers), and PLoS One (113 papers). The first authors were Rafael Denadai (13 papers), Gentile Pietro(12 papers), Khouri Roger(6 papers). The most productive countries and institutions in this field were the United States (1 646 papers), China (853 papers), and Italy (383 papers). The organizations with the largest number of publications were the University of Pittsburgh (96 papers), Shanghai Jiao Tong University (78 papers), and Milan University (63 papers). There were 87 research categories in the literature related to fat transplantation, of which surgery was involved mostly. Visual analysis of Cites Pace5.7.R5W software showed that 4 901 references had established a co-citation network consisting of 381 nodes, 608 links and 12 clusters. There were 69 599 keywords in the literature, and the top five keywords from high to low were "transplantation" "adipose tissue" "stem-cell" "tissue" , and "obesity" . In the literature, the keywords with the highest intensity of outburst was "outcome" , and the keywords with the longest duration of outburst was "cartilage" . In recent years, the five keywords with outburst were "liver disease" "trial" "stromal vascular fraction" "outcome" , and " Akkermansia muciniphila" . VOSviewer1.6.16 software visualization clustering result showed that the application of fat transplantation in plastic surgery, the source of adipose tissue and its survival mechanism in vivo, and the laboratory research on fat regeneration were the three hot spots in the field of fat transplantation technology.

Objective:To systematically review the characteristics of sleep patterns in the elderly with subjective cognitive decline (SCD) and the relationship between subjective cognitive decline and sleep disorders.Methods:Observational studies on sleep patterns in the elderly with SCD were retrieved by computer in Chinese and English databases such as PubMed, Embase, Web of Science, ScienceDirect, China National Knowledge Infrastructure (CNKI) , WanFang Data and VIP, and the retrieval time was from the establishment of the database to March 31, 2020. Two researchers independently conducted article screening, data extraction and quality evaluation according to the standard. The random-effects model was used for Meta-synthesis of studies with data that could be pooled, and descriptive analysis for studies that could not be pooled.Results:A total of 12 articles were included, with a total sample size of 67 474 cases. The prevalence of SCD in the elderly was 25.9% (95% CI: 6.4%-52.5%) . The sleep patterns of the elderly with SCD were characterized by decreased total sleep time, prolonged wake-time after sleep onset, and frequent awakenings at night. Compared with the normal elderly, the elderly with SCD had a higher risk of poor sleep quality, insomnia and excessive daytime sleepiness ( OR=2.1, 1.15, 2.6) , and excessive daytime sleepiness (ESD) increased the risk of SCD in the elderly ( OR=6.06) . Conclusions:Compared with the normal elderly, the overall sleep quality of the elderly with SCD is poor, and sleep disorders can increase the risk of SCD in the elderly. Existing studies have differences in the diagnostic criteria of SCD, and future studies need to further confirm the causal relationship between SCD and sleep disorders in the elderly.
