Objective To comprehensively grasp the grassroots medical institutions blood transfusion(blood) management present situation,put forward improvement strategy for the universality of existence weak link,the stand-ardized management of clinical blood transfusion to strengthen grass -roots medical institutions to provide necessary theoretical support.Methods 62 grassroots medical institutions blood transfusion(blood)in Yantai district were selected as the research subjects,to set the planning,layout,basic construction standards,related technology and equipment application aspects of quantitative evaluation,preliminary conclusions.Results By examination of 62 grassroots medical institutions transfusion quality management level both in terms of hardware and software facilities, emergency plan formulation,system file support informatization construction,staff education training,etc,found many problems,there was a certain gap between the existing department of blood transfusion standards.Conclusion The current grassroots medical institutions transfusion management is conditioned by the objective conditions,there are many problems,such as not improved,will cause a certain hidden trouble on the safety of clinical blood transfusion. Therefore,should combine their own reality,strengthen the quality of blood transfusion management system construc-tion,and give full play to the supervision and management of the hospital transfusion quality management committee. At the same time,the local administrative department of health also should formulate corresponding policies,ensure transfusion management level significantly increased.

BACKGROUND:A large number of studies have confirmed that anterior approach and posterior approach for multilevel cervical spondylotic myelopathy were effective, but there is stil no conclusion in which one is better.
OBJECTIVE:To systematical y assess the clinical effectiveness and safety of anterior approach versus posterior approach for multilevel cervical spondylotic myelopathy.
METHODS:The databases such as The Cochrane Library (Issue 3, 2013), PubMed (from 1966 to March 2013), OVID (from 1950 to March 2013), EMbase (from 1966 to March 2013), Chinese Biomedical Literature Database (from 1978 to March 2013), WanFang Database (from 1998 to March 2013), China National Knowledge Infrastructure (from 1999 to March 2013) were electronical y searched and five relevant journals were searched by hand to col ect the randomized control ed trials or non-randomized control ed trials about the clinical effectiveness and safety of anterior approach versus posterior approach for multilevel cervical spondylotic myelopathy. Two reviewers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, and assessed the methodological quality of included studies. Then the meta-analysis was performed by using RevMan5.2 software.
RESULTS AND CONCLUSION:A total of 11 control ed trials involving 814 patients were included. Meta-analysis results showed that, compared with posterior approach, postoperative Japanese Orthopaedic Association scores were better (P<0.000 01), improvement rate of neurological function was higher (P=0.000 3), the incidence of C5 root palsy was lower (P=0.007), but operation time was longer (P<0.000 01), amount of intraoperative bleedin g was larger (P=0.000 7), incidence of adjacent segments degeneration was higher (P=0.01), incidence of postoperative complications was higher (P<0.000 01) and the rate of secondary surgical procedures was higher (P=0.003) after anterior approach. Additional y, there were no differences between the two groups in the cervical range of motion (P=0.56). For quantity limitation and low methodological quality of included studies, this conclusion stil needs to be further proved by performing more high-quality and large-scale randomized control ed trials.

Objective To investigate the prevalence of DUOX2 mutations in Chinese patients with congenital hypothyroidism (CH) and to discuss the inheritance pattern of DUOX2 gene.Methods Blood samples were collected from 91 CH children and their genomic DNA was extracted from peripheral blood leukocytes.All exons and exon-intron boundaries of DUOX2 were analyzed by target next-generation sequencing and family trios was established to study the inheritance pattern of DUOX2 gene.Results Fifty-four out of 91 children with CH carried DUOX2 mutation, with a prevalence of 59.34%.Of the 54 CH children, 36 carried DUOX2 biallelic mutations.In all 12 family trios with probands carrying biallelic DUOX2 mutations, the parents carried heterozygous DUOX2 mutations while still showing normal thyroid function, suggesting that CH caused by DUOX2 mutations is inherited in an autosomal recessive manner.Conclusion DUOX2 gene is one of the most frequently mutated genes in Chinese CH patients and its inheritance pattern is an autosomal recessive one.

BACKGROUND: Segmentectomy can retains more healthy lung tissue than lobectomy, but it remains controversial in oncology for early stage lung cancer. The aim of this study is to discuss the problems of video-assisted thoracic surgery (VATS) segmentectomy in early stage lung cancer, by analyzing the clinical and pathological data of 35 cases and reviewing the literature. METHODS: There were 35 patients who received segmentectomy by complete video-assisted thoracic surgery, from May 2013 to July 2017, in single operation group in the Third Hospital of Peking University. We analyzed the patient's clinical and pathological data, intraoperative and postoperative complications, lymph node number and metastasis its situation, and compared postoperative pathology and preoperative computed tomography (CT) imaging type. In 35 cases of segmentectomy, there were 11 males and 24 females, with an average age of 57.7 years old. The lesions located in the right upper lobe were 8 cases, in the right lower lobe were 8 cases, in the left upper lobe were 13 cases, in the left lower lobe were 6 cases. The mean maximum diameter of CT imaging was 12.7 mm, and the largest diameter of hilar and mediastinal lymph nodes was less than 10 mm. 23 of them were ground glass predominating and 12 were solid components predominating. RESULTS: All 35 cases were successfully completed VATS anatomical segmentectomy. The average operation time was 153 minutes, the amount of bleeding was 51 mL. There were 10 cases of air leakage after operation, all of which were not more than 3 days. There was contralateral atelectasis in 1 case, chylothorax in 1 case. The average length of hospitalization was 6.1 days. There was no other complications outpatient related to surgery, in 30 days after discharge. The pathological changes were as follow, 2 cases of metastatic tumor, 8 cases of benign lung disease and 25 cases of primary lung cancer. In the 25 cases of primary lung cancer, there were 14 cases of invasive lung adenocarcinoma (7 cases were groundglassopacity (GGO) predominating in CT imaging), 4 cases of micro-invasive adenocarcinoma (3 cases were GGO predominating in CT imaging), 6 cases of adenocarcinoma in situ (all were pure GGO in CT imaging), 1 case of lung squamous cell carcinoma (mainly composed of solid in CT imaging). An average of 7.2 lymph nodes were removed in 25 cases of lung cancer, and all lymph nodes had no metastasis. CONCLUSIONS VATS anatomical segmentectomy is technically safe and reliable, and the indications for lung cancer need to be strictly controlled. Its advantages still need to be confirmed by prospective randomized controlled trials.
