Objective:To identify the novel intronic transcripts containing 11q13.5 HERV-W gag sequence, and explore the modulation of the transcripts on the alternative splicing of host gene PTD015. Methods:Half-nested PCR and touchdown PCR were used to amplify the target transcripts. The transcripts were cloned and sequenced. The plasmids inserted with the target transcripts were transfected into JEG3 cells and the alternative spliced mRNA levels of PTD015 were measured with real time PCR. Results:A 1 739 bp novel intronic transcript containing 755 bp 11q13.5 HERV-W gag sequence, 527 bp 5′ long terminal repeat and 457 bp sequence on the 5′-end of 11q13.5 HERV-W was identified. The intronic antisense transcripts significantly down-regulated the alternative spliced mRNA levels of PTD015. Conclusion:The intronic antisense transcripts originating from the second intron of gene PTD015 could modulate the alternative splicing of the host gene PTD015.

Schizophrenia is a common but complex mental disorder affected by multiple factors. Forensic psychiatric assessment of schizophrenia involves evaluations on many aspects, but there is no effective biological identification index for schizophrenia. Researches indicate that dysfunction of dopaminergic neurotransmission plays an important role in the pathogenesis of schizophrenia. Our study reviews the classification, genetic structure of dopamine receptors and the recent pertinent studies between the dopamine receptors and schizophrenia and its forensic significance.

As the actual clinical reflecting of transform Chinese medicine special curative effect, Chinese medicine preparation not only satisfies the need of hospital clinic, scientific research and teaching, but also plays an important role in deepening medical and health system reform, improving people's health level and contributing to the economic growth. However, some problems about administration and approval (tending to western medicine), contraction of the scale, lack of synchronization for clinic and scientific research, and the imbalance of regional development make Chinese medicine preparation move forwards slowly in contradiction. It has not only reduced the effectiveness of the Chinese medicine preparation in hospital clinic, but also brought bad effect on modernized development of Chinese medicine preparation. Research shows that main influencing factors of status quo of Chinese medicine preparation in medical institution include imperfect laws and regulations, high cost than income, and shortage of talents in preparation research. The analysis indicated that the necessary measures to break the contradiction, improve clinical effect of Chinese medicine, and promote the modernization development of Chinese drugs preparation were as follows: government and related departments should strengthen the supporting force in policy by adjusting the examination and approval policy, speeding up dispensing use, reforming pricing system, including into medicare reimbursement, integrating advantage resources and so on; medical institution should actively carry out research and development of traditional Chinese Medicine through drawing the traditional and modern essence, reserving professional talents, and developing characteristic preparation; companies cooperate with hospitals for complementary advantages, which can rapidly transform Chinese medicine preparation into clinical practice.

Aiming at the shortcomings of the traditional nuclear medicine teaching model and attempting to adapt to the needs of the development of clinical nuclear medicine,we changed teaching methods,strengthened practice teaching,performed online learning,introduced the self-made teaching materials,enriched the teaching contents,proposed the concept of comparative imaging and reformed on examination method.These measures greatly improved students' interests in learning and clinical thinking ability and helped students understand and master the theoretical knowledge of medicine.

Objective:To review clinical experience of PICC parenteral nutritoin in the acute and severe patients.Methods:Basilic vein,median vein and brachiocephalic vein were selected for PICC.Results:Insertion and use of PICC were successful in 56 cases with success rate of 93.33%.The parenteral nutrition was carriedout in 32 cases.There was no infection and phlebitis.2 cases failed in puncture. Conclusion:There was important clinical significance with the use of PICC in acute and severe patients.

Objective We reported previously that single nucleotide polymorphisms SNP) + 11G ＞ A in intron 3 of the human urate transporter 1 (hURAT1) gene are associated with hyperuncaemia in Han Chinese.The aim of the present study was to evaluate the effect of the variants on hURAT1 function.Methods The wild-type,mutant-type hURAT1 and exon 5-null hURAT1 were constructed,and respectively microinjected into the zebrafish embryo yolks.The subcellular localization of different genotypes of hURAT1 was detected by confocal laser scanning microscope.Results Compared with wild type,the mutant recombinant plasmid transcribed two types of mRNA spliceosome,the wild type and the exon 5-null type.The hURAT1 wild type protein was prominent localized on cell membrane,while the mutant type and exon 5-null hURAT1 proteins were distributed uniform in the cytoplasm but not on the cell membrane.Conclusion The hURAT1 variant + 11 G ＞ A resulted in an alternative splicing of hURAT1 mRNA-exon 5-null type.Its protein product exhibited a different subcellular localization compared with that of wild type.

To explore the way of quantified diagnosis of blood stasis syndrome (BSS) and the essence of BSS.

Objective To explore the relationship between the MRI enhancement ratios of liver parenchyma in hepatobiliary phase with gadobenate dimeglumine (Gd-BOPTA)and liver function.Methods Fifty-nine patients who underwent Gd-BOPTA-enhanced MRI were retrospectively enrolled in the study.The enhancement ratio of signal to noise ratio and enhancement ratio of the contrast ratio were calculated.The relationships between the enhancement ratio and CTP grading and MELD score were analyzed.Results The signal enhancement ratios in hepatobiliary phase in patients with CTP A classification were higher than those with CTP B classi-fication (P <0.01).Meanwhile,the ratios in patients with MELD scores less than 10 points were higher than those with MELD scores more than 10 points (P <0.01).Conclusion The MR enhancement degree of liver parenchyma in the hepatobiliary phase with Gd-BOPTA may reflect the liver function.
