Genome editing is defined as highly-effective and precise modification of cellular genome in a large scale. In recent years, such genome-editing methods have been rapidly developed in the field of industrial strain improvement. The quickly-updating methods thoroughly change the old mode of inefficient genetic modification, which is "one modification, one selection marker, and one target site". Highly-effective modification mode in genome editing have been developed including simultaneous modification of multiplex genes, highly-effective insertion, replacement, and deletion of target genes in the genome scale, cut-paste of a large DNA fragment. These new tools for microbial genome editing will certainly be applied widely, and increase the efficiency of industrial strain improvement, and promote the revolution of traditional fermentation industry and rapid development of novel industrial biotechnology like production of biofuel and biomaterial. The technological principle of these genome-editing methods and their applications were summarized in this review, which can benefit engineering and construction of industrial microorganism.

Several signaling pathways are involved in clonal proliferation of lymphoma cells and disease progression. It has been shown that cyclic adenosine monophosphate (cAMP) signaling pathway, as an important intra-cellular messenger delivery system, is related to modulation of multiple physiological processes including cell prolifer-ation, secretion, metabolism and apoptosis. Manipulating the cAMP signaling pathway can induce cell cycle arrest and apoptosis of various malignant lymphoid cells, which involves mitochondria-dependent apoptosis and cAMP-modulated protein kinases as well as changes of intracellular mediators. In-depth research and analysis of cAMP-induced apoptosis in lymphoma cells would provide potential targets and possible therapeutic means for the treatment of lymphoma.

Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.

Background:Serum levels of pepsinogen( PG),gastrin-17( G-17)and Helicobacter pylori( Hp)infection are closely associated with gastric cancer. Studies on relationship of serum levels of PG and G-17 with Hp infection in Uygur and Han population with gastric cancer in Xinjiang area are rare. Aims:To investigate serum levels of PG and G-17 and their relationships with Hp infection in Uygur and Han population with gastric cancer in Xinjiang area. Methods:A total of 198 Uygur and 50 Han gastric cancer patients were enrolled,and healthy people with the same race were served as normal controls. Serum levels of PGⅠ,PGⅡ,G-17 were determined by ELISA,PGⅠ/ PGⅡ ratio(PGR)was calculated. Urea breath test and stool Hp antigen test were used to detect Hp infection. Results:Serum PGⅠ level and PGR in Uygur and Han patients with gastric cancer were significantly decreased than those in corresponding control groups(P < 0. 05),and serum levels of PGⅡ and G-17 were significantly increased(P < 0. 05). Serum PGⅠ level and PGR in Uygur gastric cancer patients were significantly decreased than those in Han gastric cancer patients(P < 0. 05),and serum G-17 level was significantly increased(P < 0. 05). Hp infection rate in Uygur and Han patients with gastric cancer were significantly increased than those in corresponding control groups( P < 0. 05). Serum level of PG Ⅰ and PGR were significantly decreased in Han gastric cancer patients with Hp-positive than in Hp-negative patients,and serum levels of PGⅡ and G-17 were significantly increased(P < 0. 05). Serum levels of PGⅠ,PGⅡ and G-17 were significantly increased in Uygur gastric cancer patients with Hp-positive than in Hp-negative patients,PGR was significantly decreased(P < 0. 05). Serum levels of PGⅠ,PGⅡ and PGR were significantly increased in Uygur gastric antral cancer patients than in gastric corpus cancer and proximal gastric cancer patients(P < 0. 05). Conclusions:Decreased serum PGⅠ level,PGR and increased serum level of G-17 can be used as biomarkers to screen gastric cancer in Uygur and Han population in Xinjiang area. Hp infection in Uygur and Han patients with gastric cancer is related to the changes of serum level of PGⅠ,PGR and G-17.

Objective To analyze retrospectively the result of nonspecific mastitis diagnosed by mammography and color Doppler's ultrasonic, and to improve the diagnosis accuracy of nonspecific mastitis as well as the ability to identify with breast cancer.Methods 31 cases of nonspecific mastitiswere examined by mammography and color Doppler's ultrasonic.All cases were punctured by biopsy or surgery, and confirmed by pathology.Results The coincidence rates between mammography and color Doppler's ultrasonic with pathology were 64.5% and 67.7% respectively.The coincidence rate between the combined mammography and color Doppler's ultrasonic with pathology were 87.1%.There was no statistically significant difference between the two separate inspection methods (P>0.05).Conclusion Mammography and color Doppler's ultrasonic have their own advantages in the diagnosis of nonspecific mastitis, and are easy to be confused with breast cancer.Combining mammography with ultrasonography can improve the accuracy of unspecific mastitis diagnosis and the ability to identify breast cancer.

The effects of high frequency jet ventilation(HFJV) on brain resuscitation had been investigated in 28 cats in which simple brain functional failure was produced by occlusion of both carotid and both vertebral arteries. The results suggested that HFJV could improve endurance of cats when subjected to brain ischemia, raise the survival rate of cats with reversible brain functional failure, and prolong the survival time of cats with permernent brain functional failure. The mechanisms of how HFJ would exert beneficial effect on brain resuscitation was discussed.
