Objectives　To investigate the effect of nitric oxide(NO) on hepatic steatosis caused by total parenteral nutrition(TPN) in rats.Methods　Thirty Wistar rats were randomly divided into five groups: Group A,normal control; Group B,TPN group;Group C,TPN plus L-arginine; Group D,TPN plus NG-nitrio-L-arginine methyl ester(L-NAME，NOS inhibitor); Group E,TPN plus L-arginine and L-NAME.At the seventh day,liver function tests were performed and the livers were resected to test the lipid and nitric oxide content,and nitric oxide synthase activity.Results　The hepatic lipid content 〔triglycerid(μmol/g),cholesterol(μmol/g)〕in group B significantly increased compared with group A （39.3±2.4、13.1±1.1 vs.6.9±0.8、5.6±0.6）(P＜0.05).That was higher in group D（49.7±6.2、14.1±1.7）than in group B(P＜0.05),whereas that was lower in group C（18.2±4.4、7.3±3.1）than in group B(P＜0.05).The activity and distribution of NOS in the liver were associated with the content and distribution of hepatic lipid.Conclusions　NO produced by the liver may protect hepatic steatosis caused by total parenteral nutrition in rats.

Objective To study the relationship between HLA-DRB1alleles and the systematic lupus erythematosus of the Zhuang Nationality in Guangxi Province.Methods Allele polymerase chain reaction-sequence specific primers(PCR-SSP)were used to study the HLA-DRB1allele genes in52patients with SLE and70healthy controls of the Zhuang Nationality in Guangxi Province.Results The allele frequencies of HLA-DRB1*1401and HLA-DRB1*16were significantly less in SLE patients than those of the controls(RR=0.28,? 2 =5.00,P=0.02and RR=0.39,? 2 =3.95,P=0.05).HLA-DRB1*08,DRB1*11and DRB1*13alleles were not found in these two groups.Conclusion Our data suggest that the HLA-DRB1*1401and HLA-DRB1*16might be protecting genes for SLE in Guangxi Zhuang nationality.No susceptible gene is found in our study.

Objective To evaluate the efficacy and adverse events of oxcarbazepine(OXC) on the children with partial epilepsy.Met-hods Sixty-four children with partial epilepsy were divided into 2 groups.Forty-one newly diagnosed patients who had never accepted standard therapy entered monotherapy group,and 23 patients who had many anti-epileptic drug(AEDs) in turn with poor efficacy served as add-on therapy group.The initial dose was 4-8 mg/(kg?d).The dosage was increased by one time every 2 weeks,and should not exceed 10 mg/(kg?d) in each time.The maintenance dose was 28-40 mg/(kg?d).With open-label autocontrol method,the efficacy and adverse events of OXC were analyzed during the first 6 months of treatment both in 2 groups.Results The effective rates were 85.4%,69.6% and 79.7%,in monotherapy,add-on therapy and total groups.The seizure free rates were 53.7%,17.4% and 40.6%.It showed that the seizure frequencies between 2 groups at 6 months after therapy were significantly difference(P0.05).The common adverse events were dizziness,headache,fatigue and nausea.Six patients had dropped out because of rashes,however,they all recovered after drug withdrawal and nonspecific therapy.Conclusion The efficacy of OXC is sustained with good safety and tolerability profiles on the treatment of children patients with partial epilepsy.

The Ministry of Education has carried out “the Project of Educational Assistance to the Western District Colleges” since June, 2001. Peking University is the assistance partner to help Shihezi University. The implementation of the Project has greatly promoted the development of Shihezi University in various aspects, such as talent training, discipline construction, cultural and academic exchanges, etc.

Colorectal cancer (CRC) is one of the most common digestive system neoplasms in China. Recently, the morbidity and mortality rates of CRC continue to increase with the improvement of people's living standard and the change of the dietary structure. It was accepted that the etiology of colorectal cancer is a multi-factor and multi-step process. However, the mechanism of CRC is still unclear. MicroRNAs (miRNAs) are a class of -21 nucleotide non-coding RNAs and function as a negative regulator of gene expression after transcription, participating in tumor angiogenesis, tumor cell proliferation and invasion. MicroRNA-21 (miR-21), as an important oncogenic RNA, plays a vital role in the development and progression of CRC. This review summarizes the advances in research on miR-21 in colorectal cancer.

Conventional CT plays an important role in the diagnosis, staging, radiotherapy target delineation, and prognosis of NSCLC, but it still has many limitations.PET/CT has been widely used in the diagnosis and treamtent of lung cancer.In particular, PET/CT metabolic parameters have great guiding significance in the prognosis of NSCLC patients undergoing radiotherapy, and may be superior to many clinical indices.This review summarizes the advances in the application of PET/CT in the prognostic evaluation of NSCLC patients undergoing radiotherapy.

The standard ofClassificationandDetermination of Physical Constitutions in Traditional Chinese Medicine (TCM), which was issued by the China Association of TCM in 2009, has been promoted and implemented. However, we found that the criteria were inconsistent with the principles and methods of constitution classification in TCM after serious research. The features for physical constitution classification were repetitive and redundant without clear boundaries among them. Furthermore, there were poor correlations among different factors within a single physical constitution. Accordingly, it was suggested that the theory of physical constitutions in TCM should not be confused with and treated as the science of it. Because the standard ofClassiifcationandDetermination of Physical Constitutions in TCM is not mature enough, we should be cautious when applying it.

There was severe logical contradiction among the basic concepts in Chinese medicine such as syndrome, symptoms and signs, etiopathogenisis and pathogenesis .In this paper, from the comparative reseaech of the different versions of Basic Theory of Traditional Chinese Medicine (TCM) used in higher colleges and universities of TCM in recent 50 years,higher Colleges of Chinese medicine materials, it cleared up the evolution of the basic connotation of syndrome, symptoms and signs, pathogens and pathogenesis, and revealed fundamental reason for the occurance of logical contradiction.
