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.

Autophagy is a physiological process which delivers the mutant cytoplasmic proteins and dysfunctional subcellular organs into lysosomes for degradation to generate fuel in the deficiency conditions. It is mainly classified into macroautophagy, microautophagy and chaperon-mediated autophagy (CMA), as well as the selective autophagy such as mitophagy and aggrephagy. This review mainly introduces the key molecular markers of macroautophagy, CMA and mitophagy.

Hand, foot, and mouth disease (HFMD) is a viral infectious disease regarded to be a public-health problem worldwide. Since the 1990s, HFMD began to spread in the Asia-Pacific region (especially in South-East Asia). HFMD outbreaks have occurred in mainland China frequently since 2008, and the morbidity and mortality of HFMD has continued to increase in recent years. In mainland China, enterovirus A serotype enterovirus A71 (EV-A71) and coxsackievirus A16 (CVA16) have been the major pathogens of HFMD during these years. However, the etiological spectrum of HFMD changes with time. This review focuses mainly on the etiological spectrum of HFMD and changes in epidemic patterns in mainland China.

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 investigate the optimum formulation and preparation process of Yuxiawenya dispersible tablets.Methods The formula of Yuxiawenya dispersible tablets were optimized by orthogonal design in terms of dispersible uniformity test.Results The tablets were prepared by moist granulation method with 1% polyvidone k30(PVPK30) ethanol solutionsas as moistening agent,microcrystalling cellulose(MCC) as diluents,and sodium croscarboxymethyl starch(CCMS-Na) as disintegrant.The disintegration time of dispersible formulation was

Objective To study the mechanism of haze formation after photorefractive keratectomy (PRK). Methods 27 adult New Zealand white rabbits were employed in this study.24 of them received PRK in the right eye and laser in situ keratomileusis (LASIK) in the left eye at the same time and under the same condition for -10\^00D ablation at once,24hour,1 week,2 week,1month,3 month,6 month and 12 month after surgery,the corneas were examined periodically by slip\|lamp microscopy for haze formation,and the both eyes of 3 rabbits were enucleated,the corneas were studies with light microscopy;transmission electron microscopy;immunohistochemical evaluation for extracellular matrix,including collagen type Ⅰ,type Ⅲ,type Ⅵ,cellular fibronection,tenascin and laminin;RT\|PCR detection for mRAN of collagen type Ⅰ. Results The incidence of haze was 100% after PRK.No haze formation after LASIK.Haze was located at the anterior stroma immediately adjacent to the ablated areas.The change of structure and composition which correlated with haze formation was due to a combination of the following factors:the basement membrane of corneal epithelium was discontinuous;A new layer of subepithelium tissue was synthesized;fibroblast was increased in number and activated;the collagen fibrils were disorganized.The diameter of fibrils and the space between the fibrils were irregular in the anterior stroma;The newly synthesized extracellular matrix inculding collagen type Ⅰ,type Ⅲ,type Ⅵ,cellular fibronection,tenascin and laminin were deposited in the anterior corneal stroma.Conclusion\ The formation and disappearing of haze was the result of interreaction between fibroblast and extracellular matrix.The destruction of basement membrane of corneal epithelium and Bowmen's member after PRK is initializing factor during haze formation.\;[

Objects:To describe the distribution regularity of constitutional types of Chinese medicine in general population and analysis the characteristics of different social demography population through epidemiological investigation of constitutional types of Chinese medicine in general population.Methods:Using 21,948 cases large sample data of Chinese medical constitution cross-section survey from general population of nine provinces and municipalities(Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and He’nan),from December 2005 to January 2007.8,448 samples in accord with sample data from 1% nationwide population survey in 2005,which could representative the general population of China were randomly selected.Using the standardized Constitution in Chinese Medicine Questionnaire(CCMQ) to evaluation the scores of all kinds of Constitutional types(Gentleness type,Qi-defi ciency type,Yang-defi ciency type,Yin-defi ciency type,Phlegm-wetness type,Wet-heat type,Blood-stasis type,Qi-depression type,Special diathesis type).Application Discriminant Analysis to distinguish the individual Constitutional types,and analysis the distribution regularity of constitutional types of Chinese medicine in general population.Variables grouped by social demographic,use ?2 test to compare the differences in each sub-group’s constitution composition.Results:In the general population in China,Gentleness type accounted for 32.14 percent,eight pathological constitutions accounted for 67.86 percent,and the former three types of eight pathological constitutions were Qi-defi ciency type,Wet-heat type and Yang-deficiency type,which accounted for 13.42 percent,9.08 percent and 9.04 percent respectively.The composition ratio of constitutional types in different geographical,gender,age,marital status,occupation and education level were different,and the difference was signifi cant(P
