The concept of cause in TCM is different from the etiology concept in modern TCM. In modern TCM,the etiology is equal to pathogenic factors.At present,the significance of 'pathogenic factors'in TCM was affected by modern TCM,and this description can't show the essence of TCM theory and is not conducive to the development of cause theory of TCM.

The population of drinking underground water occupied 76.4%,of which,drinking spring water occupied 83.2% and drinking well water occupied 4.6%. The population of drinking ground water occupied 23.6%,of which,drinking river water occupied 53.6%,drinking lake water occupied 0.2%. There were 638 centralized water supply plants,of which,only 11 water plants had complete water treatment. The dispersed water supply was consisted of manpower(84.7%),handpump(9.8%) and machine(5.5%). 51 of 113 water samples were up to standard,the overall eligible rate was 45.1%,of which the eligible rate of ground water was 25.9%,underground water was 51.2%,centralized water supply was 56.8%,dispersed water supply was 15.6%,showed the significant difference(P

BACKGROUND:Immune rejections after organ transplantation or serious adverse reactions due to immunosuppressive drugs show a lack of effective treatments and poor therapeutic outcomes. Therefore, we try to find an effective immune suprresion method in combination of the latest immunomodulatory achievements. OBJECTIVE:To construct a lentiviral vector overexpressing indoleamine 2,3-dioxygenase (IDO). METHODS:(1) The IDO gene that was successful y contructed was inserted into lentiviral packaging plasmids GV308 to construct GV308-IDO lentivirus packaging plasmids. (2) The 293T cel s with 80%confluence were co-cultured with 5'LTR and 3'LTR, basic elements of lentiviral packaging auxiliary components, including Psi, cPPT, 3FLAG, TetR, IRES, WRPE, TetIIP, Ubiquitin Promoter, SV40 origin and HIV. RESULTS AND CONCLUSION:Western blot assay showed that in 10 g/L agarose gel electrophoresis, there was a target fragment at Mr 48 000. This value was consistent with the size of IDO protein. RT-PCR results showed visible IDO expression in 293T cel s. These findings suggest that IDO fusion gene has been successful y reorganized in the lentiviral packaging plasmids.

Ob jectiev Oxidized low-density lipoprotein ( ox-LDL) induces vascular endothelial cell injury , which is one of the factors initiating atherosclerosis .This study aimed to investigate the protective effect of Tongxinluo ( TXL ) on vascular endothelial cells with ox-LDL-induced injury . Methods Human umbilical vein endothelial cells ( HUVEC ) were cultured in vitro and divided into five groups:normal control, oxidative stress injury (OSI) model, and high, medium and low dose TXL.The HUVECs were incubated with ox-LDL at the concentration of 30 mg/L for 24 hours to induce oxidative stress injury and then treated with TXL at 50, 100 and 150 mg/L for 4 hours, followed by 24 hour incubation with 30 mg/L ox-LDL added to the culture medium .The viability of the cells was detected by MTS assay, the nitric oxide (NO) content, superoxide dismutase (SOD) activity and mitochondrial membrane poten-tial ( MMP) in the cell culture supernatant were measured with respective kits , and the expressions of iNOS , MMP9, and NF-κBp65 proteins were determined by Western blot . Results The HUVECs of the OSI model group showed a significant decrease in cell via-bility compared with the normal control , ([73 .89 ±0.67] vs [100.00 ±2.23]%, P<0.01) but a remarkably increase after treated with medium and high dose TXL ([92.15 ±0.76]%and [ 97.19 ±1.45]%, P<0.01).The MMP, NO content, and SOD activity were markedly reduced in the model group (P<0.01) but elevated in the low, medium, and high dose TXL groups (P<0 .01).The expressions of the iNOS, MMP9, and NF-κBp65proteins were significantly up -regulated in the model group (P<0.01) but down reg-ulated in the low, medium, and high dose TXL groups (P<0.05).C on clusion TXL has the effects of anti-oxidation and anti-in-flammation and can protect vascular endothelial cells against ox-LDL-induced injury .

Objective To research the clinical outcome of atypical glandular cell (AGC)according to various subtypes of HPV infection and histological pathology results.Methods The data of the liquid-bases cytology (LBP),HPV infection and histology in 102 cases of AGC at the gynecology outpatient department of our hospital from January 1 ,2009 to February 28,2014 were collected and performed the analysis on their clinical outcomes.Results Among 67 218 cases of LBP detection,102 cases were AGC with the total incidence rate of 0.15%.In the cases of AGC-NOS,67 cases were normal or benign lesions,11 cases were precancerous lesion and malignant lesions;in the cases of AGC treading to tumor,the benign,precancerous and malignant lesions were in 7,14 and 3 ca-ses respectively.At the same time in the cases of AGC-NOS,HPV infection was in 64 cases,in which 57 cases were high risk infec-tion(type 16,52,45)and 7 cases were low risk infection(type 6,11 ).The single infection,double infection and multiple infection were in 54,6 cases respectively;in the cases of AGC trends to neoplasm,HPV infection was in 19 cases,in which 18 cases were high risk infection(type 52,16,18)and 1 case was low risk infection(type 6),single infection and double infection were in 15 cases and 4 cases respectively.Conclusion AGC may play an important role for the forecast of cervical malignant lesions.The results of differ-ent HPV subtypes infection in AGC related tumors also play a certain role in the prediction of cervical neoplasia.Their combined a-nalysis is the important signal for judging the occurrence of gynecological cervical precancerous lesion and malignant tumor,i.e., AGC combining with the corresponding HPV subtype infection not only can make a judgement for the cervical lesions,but also pro-vides the basis for predicting the high risk existence of gynecological malignant tumor and provides constructive suggestions for Chi-na regional cervical carcinoma vaccine manufacturing and promotion.
