Objective To compare the applications of half-Fourier acquisition single-shot turbo spin-echo(HASTE)sequence and true fast imaging with steady state precession(True FISP)sequence for the delineation of structures and diseases in several twin pregnancy with comorbidities and to explore the clinical value of two series of fast imaging for MRI of fetus.Methods 27 twin preg-nancy women with comorbidities were imaged with HASTE and True FISP sequences.All images were statistically analyzed in re-spect of imaging qualities and artifacts.MR signs of fetal brain were analysized.Results There were abnormal changes in brains in 7 of 27 cases.Both sequences could demonstrate the structures and lesions of the fatus.Imaging quality scores of HASTE were higher than that of True FISP,but with more respiratory blurring.Conclusion There might be varying abnormalities in central nervous system in twin pregnancy with comorbidities.Combining the demonstration abilities of HASTE and True FISP is needed when de-tecting fetus lesions,especially the brain.

OBJECTIVETo observe clinical therapeutic effect of fuzhong (supporting the middle-jiao) manipulation of tuina for infantile anorexia.

METHODSEighty-one children with anorexia were treated with fuzhong manipulation, including abdominal kneading, acupressure at Zhongwan (CV 12), Lanmen (Extra), Tianshu (ST 25), Zusanli (ST 36), Sanyinjiao (SP 6), spine pinching, warm moxibustion and warm scraping with supporting-yang cupping, three times a week, six times as a session. Onset time, therapeutic effect and TCM symptom scores before and after treatment were observed after two sessions and differences of therapeutic effect among different patterns were compared.

RESULTSSeventy-two children had the effect in one session while 41 children had the effect within half of a session. 38 cases were clinically cured, 15 cases were markedly effective, 23 cases were effective and 5 cases were failed. The total effective rate was 93.8%. Compared with before treatment, TCM symptom scores, including appetite, food intake, complexion and defecation, were all obviously improved after treatment (all P < 0.001). The clinical cured rate was 45.2% (19/42) in the pattern of dysfunction of spleen in transportation, 45.8% (11/24) in the pattern of qi deficiency of spleen and stomach, 50.0% (4/8) in the pattern of yin deficiency of spleen and stomach, 57.1% (4/7) in the pattern of liver sufficiency and spleen insufficiency, which had no obvious differences among different patterns (all P > 0.05).

CONCLUSIONThe fuzhong manipulation of tuina has quick onset time and satisfied clinical therapeutic effect, which could obviously improve symptoms and is fit for different patterns of infantile anorexia.

Objective To discuss the CT and MR imaging appearances and diagnostic value of spinal lymphoma. Methods Sixteen patients with pathologically proved spinal lymphoma (aged 8 to 63 years) were retrospectively reviewed. CT were performed in all 16 patients, and MRwere performed in 12 patients. Results Totally 65 vertebrae (cervical 15, thoracic 22, lumbar and sacrum 28) were involved. Multiple lesions were found in 11 patients. The characters of these lesions were osteolytic, osteogenic or mixed on CT. The signal intensity was hypo or iso on T1WI and iso or slightly hyper on T2WI. The extradural involvements were more extensive than that of the vertebrae both on CT and MR images. Conclusion Lesions of spinal lymphoma usually demonstrate various bone destructions on CT, and hypo or iso intensity on T1WI as well as iso or slightly hyper intensity on T2WI, tending to involve paraspinal or extradural space, and longitudinal involvements are often seen along the vertebral canal. MRI is more sensitive than CT in detecting spinal lymphoma lesions.

Objective Adopt the method of brachial plexus block by a noodle biopsy and pressing the root of interscalene,to discuss the effective of this method on the operation of shower and upper limb.Methods Summarize 182 cases of patients who got the upper limb operation,compared the patients adopting a noodle biopsy and pressing the root of interscalene to block,to the cases which un-pressing the interscalene.Evaluate the anesthesia on sense and movement and record the complicating disease.Results It got a satisfied result from a noodle biopsy and pressing the root of interscalene to block.In this case,all of the sense and movement including shower has disappeared,and has absolutely effect on analgesia.All of the patients avoid to be used herbal supplements and however to complicating symptom.Good rate 97％,compared to 73％ cases of un-pressing.Pressing the interscalene to block is better than un-pressing,on feet nerve,axillary nerves,the median nerve and C4 nerve.Conclusion A noodle biopsy and pressing the root of interscalene to block is a effective and simple method,it needn't special equipment and has a absolutely and extensively block result on the shower and upper limb operation.

Objective To understand the clinical characteristics of systemic lupus erythematosus with Antiphospholipid syndrome (SLE-APS).Methods The clinical data of 39 cases of SLE-APS were collected and analyzed retrospectively. Results Thirty-one patients had 48 thrombosis episodes in total, among which the most common presenting manifestations were deep venous thrombosis and stroke. 12 of 26 married women had fetal morbidity. The prevalence of anticardio lipin antibody (aCL) and lupus anticoagulant ( LA) was 72% and 41% , respectively. 24 patients had SLE at first,on an average of 9. 5 years later they had the characteristics of APS, 12 patients had thrombosis episodes or fetal morbidities ,4. 8 years later they developed into SLE,and 3 patients had the characteristics of SLE and APS from the onset The SLEDAI was less than 5 in five cases when they had thrombosis episodes or fetal morbidities.Conclusions The incidence of thrombosis episodes or fetal morbidities increased in SLE-APS patients. APS occurred before, after or at the same time with SLE. SLE patients might have the clinical features of APS during the steady stage. It's very important to ask the medical history in detail and measure aCL in lupus patients to find the risk factor of APS and prevent the APS' occurrence.

GDP-mannose-3', 5' -epimerase (GME), which converts GDP-mannose into GDP-L-galactose, is essential for the biosynthesis of L-ascorbic acid in higher plants. The molecular characterization of two GME genes from rice has been reported. Firstly,both cDNAs were isolated from the rice mature leaves using RT-PCR technique. By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots. Secondly, the genomic organization of rice OsGME genes was investigated, and a similarity of splice patterns was revealed. Finally, the expression patterns of the two cDNAs have been studied in various tissues and under different stress conditions by semiquantitative RT-PCR assay. The results showed that the OsGME1 transcript was up-regulated in response to cold stress, and gibberellin might regulate L-ascorbic acid levels by affecting transcription of both OsGME genes.
