To augment the levels of diagnosis and treatment for colorectal cancer and make them standardization in China, the Ministry of Health of the People's Republic of China released Chinese Standard for The Management of Colorectal Cancer (2010) in November 4, 2010. This standard incorporates the most recent progresses in colorectal cancer, and it provides standard guidelines with respect to diagnosis, pathologic examination, surgery, adjuvant therapy in the management of colorectal cancer in China.

Xuening Granule is a traditional Chinese patent medicine based on San Huang Xie Xin Tang. The effective Component of each herbal medicine were extracted individually and then mixed together to form granules. This process avoids the chemical reactions among the drugs in order to enhance the the effects. The major contents are determined and differentiated to control its quality

OBJECTIVE To study the 16 genotypes of ?-lactamase in multidrug-resistant Acinetobacter baumannii isolated from inpatients,to know the state of multidrug resistance of A.baumannii in Urumqi.METHODS Bacterial strains were identified by system of API,and antibiotic susceptibility test was detected by K-B and microdilution according CLSI.PCR was used to determine the genotypes of ?-lactamase and compare with that in GenBank.RESULTS The antibiotic resistance rates to cefataxime and tetracycline of the isolates were the highest,(100%).Resistance rate to cefoperazone/sulbactam was the lowest(5 TEM(25%)strains and 10 OXA-23 strains(50%)from 20 strains multidrug resistant A.baumannii).CONCLUSIONS There is a high percentage of multidrug resistance production of A.baumannii in Urumqi.The ?-lactamase is focused on TEM and OXA-23;it is deserved to make further augmentation of epidemiology surveillance on ?-lactamase.

AIM: To evaluate the safety and effectiveness of 23G and 20G vitreous cutting system in silicone oil extracting operation.
●METHODS:A total of 98 cases (98 eyes) patients, after 3- 6mo silicone oil filling with retinal attachment and suitable for retrieving silicone oil. Patients were randomly divided into two groups. 20G vitreous cutting system group including 48 cases ( 48 eyes ) and 23G vitreous cutting system group including 50 cases ( 50 eyes ) . A series of comparative analyses were conducted on the times for set up and closing the passage and the time for taking the oil time on the two groups:intraocular pressure of preoperative and of postoperative for 1, 3d, 1wk, 3 and 6mo. The comparisons were also made between the best corrected visual acuity of preoperative and postoperative. The section inflammation of postoperative 1, 3d, 1mo were compared. Complications were compared between intraoperative and postoperative.
●RESULTS:Establishing surgery channel for 20G and 23G group were ( 243. 54 ± 51. 17 ) s and ( 91. 16 ± 21. 37 ) s respectively;closing wound time were (235. 04 ± 42. 89) s and (86. 04±21. 76)s. Extracting oil time were (6. 7±1. 65) min and ( 7. 35 ± 2. 02 ) min. There was a significant difference ( P<0. 01 ) between establishing the operation channel time and close the incision time. There was no significant difference between two groups in the extracting oil time (P>0. 05). The first day was statistically different ( P< 0. 05 ) but the rest of the time point of intraocular pressure had no statistical difference ( P >0. 05). The best corrected visual acuity for 20G and 23G group preoperative and postoperative after 6mo were:4. 21 ± 0. 61, 3. 91 ± 0. 64; 4. 03 ± 0. 46 and 4. 22 ± 0. 39 respectively. There was no significant difference between the two groups (P>0. 05). There was significant difference ( P<0. 05) of cells in the anterior chamber between the 20G group and 23G group of postoperative 1 and 3d. There was no statistical difference after 1mo (P>0. 05). The findings also reported that 20G and 23G group had no intraoperative complications and postoperative. For 23G group, 5 cases of temporarily had lower intraocular pressure, 1 case was retinal again, 1 case was choroid detachment. For 20G group, 1 case of temporarily had lower intraocular pressure, 3 cases were retinal detachment and 2 cases were choroid detachment.
●CONCLUSION:23G vitreous cutting system has the advantages of low operation steps, intraoperative injury. The postoperative complications of low probability, used in silicone oil is safe and effective.

Nrf2/Keap1/ARE is an important signaling pathway in maintaining the balance between peroxide and antioxidants. Once oxidative stress happened, Nrf2/Keap1/ARE would be ac-tivated to regulate the expression of downstream antioxidant pro-teins that could reduce the injury from oxidative stress and the level of oxidative stress. Recent researches show that Nrf2/Keap1/ARE signaling pathway is closely related to refractory re-spiratory diseases such as pulmonary fibrosis (PF), lung canc-er, chronic obstructive pulmonary disease (COPD), suggesting that Nrf2/Keap1/ARE signaling pathway may be a potential ther-apeutic target. This review focuses on the role of Nrf2/Keap1/ARE signaling pathway in refractory respiratory diseases in order to further understand the related mechanism and provide evidence for the diagnosis and treatment of refractory respiratory diseases.

BACKGROUND:Lung cancer stem cel s are tightly related to the treatment and prognosis of lung cancer. We can provide more references for clinical diagnosis and treatment of lung cancer through the study on the tumorigenicity and surface markers of lung cancer stem cel s. OBJECTIVE:To explore the enrichment methods for lung cancer stem cel s and cel ular tumorigenicity. METHODS:Lung cancer stem cel s were induced in serum-free culture medium containing epidermal growth factor, insulin-like growth factor 1, and basic fibroblast growth factor. Then, the expressions of related surface markers were detected using immunofluorescence method. After that, mice were implanted subcutaneous with lung cancer stem cel spheres to understand the tumorigenicity of lung cancer stem cel s. RESULTS AND CONCLUSION:Lung cancer stem cel s under serum-free induction and culture were changed to sphere-forming cel s, and the immunofluorescence detection showed that over 80%of sphere-forming cel s were positive for CCSP, SP-C and OCT4. After transplantation of sphere-forming cel s, the mice showed a high tumorigenicity. These findings indicate that sphere-forming cel s are formed after serum-free suspension culture of lung cancer stem cel s, which have a higher tumorigenicity.
