AIM: To investigate the effect of nitric oxid e (NO) and taurin on hemorrhagic shock /reperfusion injury. METHODS: Twenty-four rabbit s were divided randomly into 3 groups ( n= 8): control group and shock group and taurine group. The model of hemorrhagic shock/reperfusion was used. The activities of ni tric oxide synthase (NOS),superoxide dismutase(SOD),lactate dehydrogenase (LDH)and the contents of malondialdehyde(MDA),nitric oxide pvoducts( NO - 2/NO - 3) in plasma were observed before shock and shock 1.5 h,reper fusion 1 h ,2 h and reperfusion 3 h. RESULTS: ①During shock/reperfusion, the ac tivities of NOS,LDH and the contents of MDA,NO - 2/NO - 3 were significan tly highe r, but the activity of SOD was significantly lower in plasma of shock group than that of before shock and shock 1.5 h. ②At 3 h reperfusion, the activity of NOS and the contents of MDA, NO - 2/NO - 3 were significantly higher,bu t the act ivity of SOD was significantly lower in the lung and heart of shock group than t hat of control group. ③ Taurine(40 mg?kg -1 ,iv) attenuated all the c hanges above mentioned at total time points of reperfusion. ④ A close correlation was shown between MDA content and NO - 2/NO - 3 content in plasma, lung and i n heart. CONCLUSION: These results suggeste that NO may be involved in oxida nt-mediated shock/reperfusion, antagonistic effect of taurine on hemorrhagic shock/reperfusi on injury may be relate d to decreasing the generation of NO and anti-lipoperoxidation.

Objective:
To investigate the average dietary nutrients intake status among Chinese residents between 2010-2012, and to compare the difference between rural and urban areas.
Methods:
Data were collected from Chinese Nutrition and Health Surveillance between 2010-2012. Based on regional features and economic development levels, China's county-level divisions were classified into four types: big city, medium and small city, ordinary rural area and poor rural area. A total of 62 857 valid subjects, including 14 017, 16 539, 19 910 and 12 391 respondents in each group separately, were enrolled by Multi-stage stratified proportion to the population cluster random sampling method. The dietary survey was conducted by recalling the 24 h diet in 3 consecutive days and weighting condiment. The daily dietary intake of energy, macronutrient, dietary fiber, vitamin, and mineral substance per resident were calculated based on China Food Composition.
Results:
The average energy intake per resident in Mainland China was 9 047.1 kJ, with highest (9 719.3 kJ) in poor rural area and lowest (8 490.4 kJ) in medium and small city. The average dietary protein intake was 64.2 g, with highest (73.9 g) in big city and lowest (60.7 g) in poor rural area. The average dietary fat intake was 79.7 g, with highest (89.4 g) in big city and lowest (70.6 g) in poor rural area. The average intake of micronutrients of vitamin A, vitamin B2, vitamin C, calcium, iron, phosphorus, zinc was separately 441.9 μg, 0.8 mg, 80.1 mg, 364.3 mg, and 21.4 mg; which were lower than Chinese Dietary Reference Intakes. The percentage of population whose average intake of vitamin A, vitamin B2, vitamin C, calcium were lower than estimated average requirement was separately 77.0%, 90.2%, 67.7%, and 96.6%.
Conclusion
The supply of 3 macronutrient was sufficient in mainland China. However, it was a common issue that there was excessive intake of fat but deficient intake of micronutrients such as vitamin, calcium, iron and zinc. There were differences in nutrition intake among big city, medium and small city, ordinary rural area and poor rural area.

OBJECTIVETo compare the efficacies ofentecavir and adefovir in patients with chronic hepatitis B (CHB) and cirrhosis when administered as monotherapies using a 240-week course.
METHODSNinety patients diagnosed with CHB and cirrhosis (compensated or decompensated) were randomly divided into two treatment groups for administration of either entecavir (0.5 mg/day, oral; n =38) or adefovir (10 mg/day, oral; n =52) for 240 weeks. All participants underwent B-ultrasound and were tested for levels of HBV-DNA, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen, creatinine, alpha-fetoprotein (AFP) and various serological markers of the hepatitis B virus at baseline and at treatment weeks 24, 48, 96, 144, 192, and 240. Instances of drug-related complications and adverse reactions were recorded. Patients who did not achieve complete virological response by treatment week 48 or who experienced virological breakthrough at any time during the study course were recorded and started on an appropriate combination therapy regimen. Statistical analyses were carried out using the t-test, chi-square test, and Cox regression modeling.
RESULTSThe dropout rate in the entecavir group was 2.6% and in the adefovir group was 13.5%. At treatment week 240, significantly more patients in the entecavir group had undetectable serum HBV-DNA (91.9% vs. adefovir group: 57.8%; x2=10.362, P=0.001), a negative conversion rate of hepatitis B e antigen (HBeAg) (46.2% vs. adefovir group: 24%; x2=5.055, P=0.025), and rate of HBeAg seroconversion (23.1% vs. adefovir group: 8%, P=0.047).The entecavir group and the adefovir group showed no significant differences upon per-protocol analysis and intention-to-treat analysis, nor in the rates of hepatocellular carcinoma development (entecavir group: 8.1% vs. adefovir group: 6.7%; x2=0.000, P=1.000) or mortality (entecavir group: 8.1% vs. adefovir group: 4.4%; x2=0.051, P=0.821). The possibility of achieving undetectable serum HBV-DNA was 2.761 times higher in the entecavir group than in the adefovir group (95.0% CI: 1.630 to 4.679). The possibility of HBeAg seroconversion was 0.192 times higher for males than for females (95.0% CI: 0.046 to 0.806).
CONCLUSIONCompared to adefovir, entecavir provides high efficiency and rapid viral suppression as a monotherapy for CHB patients when administered in a 240-week course.

Objective:To understand the screening of cervical cancer in our county and provide epidemiological data for the prevention and control of cervical cancer.Methods:A total of 3 034 healthy women with 30~65 years old in Chun'an county were recruited in this prospective study from June 2015 to January 2016.All of the subjects received cervical cancer screening.The respondents were randomly divided into non-typeable HPV screening group (2018 cases) and the vision inspection with acetic acid and visual inspection with Lugol's iodine screen (VIA/VILI) group (1016 cases). Direct colposcopy or VIA/VILI visual examination was performed for those with positive HPV, and then colposcopy was performed for those with positive visual examination.The suspicious lesions tissues were applied for pathology detection.From September 2017 to February 2018, 2 363 patients who were initially negative received VIA/VILI combined with unclassified HPV examination, and those who were positive received colposcopy and pathological biopsy.The positive rate of primary screening and cervical squamous intraepithelial neoplasia disorders level 2 and above (CIN Ⅱ + ) lesion detection rate were analyzed in the two-stage screening.Results:From June 2015 to January 2016, the preliminary screening positive rate of unclassified HPV group was 11.60% (234/2 018). A total of 150 patients with positive results were recalled for colposcopy, with a recall rate of 64.10% (150/234). Among the 150 cases, 119 cases (79.33%) were positive in the unclassified HPV preliminary screening, and 31 cases (20.66%) were positive in VIA/VILI examination after HPV preliminary screening.The positive rate of VIA/VILI initial screening group was 20.28% (206/1 016), and the recall rate of colposcopy was 99.51% (205/206). A total of 108 cases underwent colposcopy with abnormal pathological biopsy examination in the two groups, and the pathological biopsy rate was 30.34% (108/356), and the pathologic biopsy CIN Ⅱ+ lesion detection rate was 297/100 000 (9/3 034). In the second round of screening from September 2017 to February 2018, 2 363 subjects were recruited back to the baseline, with a recall rate of 77.89% (2 363/3 034). In the 2 363 cases, the early screen VIA/VILI anomalies or HPV positive early screening positive rate was 17.01% (402/2 363), and the colposcopy examination the recall rate was 80.10% (322/402), and 80 cases received vaginal lens suspicious pathological biopsy, the pathological biopsy rate was 24.84% (80/322), the pathological results showed that CIN Ⅱ+ detection rate of 296/100 000 (7/2 363).Conclusion:The detection rate of precancerous suspicious lesions in cervical cancer screening in our county is lower than the national average level.On the one hand, we should strengthen the propaganda and education of active screening, improve the compliance and cooperation degree of screening objects, and improve the recall rate of suspicious cases.On the other hand, the government should invest more efforts to select the screening technology with high sensitivity, improve the screening technology of doctors at the basic screening point, and improve the detection rate of cervical cancer prelesions.
