ObjectiveTo compare the sensitivity and specificity of a new index of insulin resistance (IR) derived from plasma triglyceride and glucose with homeostasis model assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index from frequent sampling intravenous glucose tolerance test (FSIGT-ISI).Methods A total of 1024 subjects (240 normal control,335 with obesity,312 impaired glucose regulation,and 137 type 2 diabetes mellitus) were included in the present study.Standard oral glucose tolerance test,insulin release test,lipid profiles,and other biochemical markers were measured. Among them 540 subjects were selected to undertake FSIGT.TyG index is derived from plasma triglyceride and fasting glucose.TyG2 index is derived from plasma triglyceride and postprandial 2 plasma glucose.ResultsPearson correlation coefficient between TyG and HOMA-IR or FSIGT-ISI was 0.427 ( P＜0.01 ) and -0.100 ( P=0.024 ),respectively,and that between TyG2 and HOMA-IR or FSIGT-ISI was 0.455 ( P＜0.01 ) and - 0.162 ( P＜0.01 ),respectively.The sensitivity and specificity of TyG index for diagnosis of IR was 68.5％ and 63.5％ compared with HOMA-IR,and 68.5％ and49.5％ compared with FSIGT-ISI.For TyG2 index,the slightly higher sensitivity ( 81.7％ with HOMA-IR,75.7％ with FSIGT-ISI),but lower specificity (51.5％ with HOMA-IR,48.2％ with FSIGT-ISI) were found.ConclusionsBothTyGandTyG2 indices could be used as a surrogate for assessing IR in Chinese subjects.However,considering its moderately high sensitivity but low specificity,these two indices are limited in the use of large-scale epidemiological screening.

OBJECTIVETo analyze the status of dietary sodium intake of 18 - 65 years old Chinese people in nine provinces (autonomous region) in 1991 and 2006.

METHODSIn 1991 and 2006, China Health and Nutrition Survey was carried out in nine provinces, including Liaoning, Heilongjiang, Shandong, Jiangsu, Henan, Hunan, Hubei, Guangxi and Guizhou, Subjects were selected by multi-stage stratified cluster random sampling method from 18 - 65 years old people and 8235 subjects in 1991 and 7788 subjects in 2006. Sodium intake analysis was conducted across gender, regions and rural(urban) residences.

RESULTSOn average, sodium intake decreased from (6750.6 ± 3771.5) mg/d in 1991 to (4949.7 ± 2829.4) mg/d in 2006 (Z = -35.5, P < 0.01) among the 18 - 65 years old people. In 1991 and 2006, the main sources of dietary sodium were salt, soy sauce and vegetable. In 1991, the proportion were 79.6% ((5375.6 ± 3532) mg/d), 8.7% ((586.7 ± 721.7) mg/d) and 7.5% ((506.9 ± 906.1) mg/d), respectively. In 2006, the proportion were 71.5% ((3539.8 ± 2545) mg/d), 8.3% ((410.7 ± 547.9) mg/d) and 6.2% ((304.6 ± 610.7) mg/d), respectively.

CONCLUSIONSAmong 18 - 65 years old residents, sodium intake in 2006 was significantly lower than that in 1991, but still far beyond the 2200 mg/d of adequate intake level (2200 mg/d). The major source of sodium intake in Chinese diet was condiments.

OBJECTIVETo examine the differences in food and antioxidant vitamin intake in current non-smokers,light smokers,and heavy smokers.

METHODS51 115 people (24 077 male, 27 038 female) aged above 15 years who had completed providing information on smoking habit and dietary intake, were selected from 2002 national health and nutrition survey.

RESULTSAfter adjustment for geographic areas and age, data showed the smokers ate more light vegetable and alcohol, less dark vegetable and fruit than non-smokers. Male smokers consumed more energetic stuff and macronutrients than non-smokers, but female smokers had opposite trends. Light smokers (LS) consumed less antioxidant than non-smokers (NS) after adjusted for area, age, BMI and energy, with carotene (Male LS = 1824.7 microg, NS = 1964.8 microg; Female LS = 1565.4 microg, NS = 2127.4 microg), thiamin (Male LS = 0.84 mg, NS = 0.85 mg; Female LS = 0.72 mg, NS = 0.74 mg), vitamin E (alpha) (Male LS = 9.2 mg, NS = 9.3 mg; Female LS = 7.4 mg, NS = 8.1 mg), vitamin C (Male LS = 91.2 mg, NS = 94.2 mg; Female LS = 76.9 mg, NS = 87.5 mg).

CONCLUSIONSmokers had a significantly lower overall mean dietary antioxidant vitamin intake than non-smokers. Increasing the daily consumption of variety of fruits and vegetables had been recommended to reduce the risk of chronic diseases.

BACKGROUND: The perioperative hemorrhage of knee surgeries is a difficulty in clinic, and the efficacy of tranexamic acid to reduce postoperative bleeding has attracted more attention, but choosing which administrations remains controversial. OBJECTIVE: To investigate the efficacy of tranexamic acid by intravenous injection or articular injection for reducing the perioperative hemorrhage of total knee arthroplasty. METHODS: Sixty patients undergoing unilateral total knee replacement were enrolled, and were then randomized into three groups (n=20 per group): no tranexamic acid administration (group A); intravenous dropping of 15 mg/kg tranexamic acid before tourniquet application plus 10 mg/kg tranexamic acid at 3 hours postoperatively (group B); articular injection of 50 mL saline diluted with 1 g tranexamic acid through a drainage tube (group C). Two-hour closure of drainage tube was performed in all patients. The postoperative dominant and hidden blood loss, blood transfusion rate, pulmonary embolism as well as lower extremity deep venous thrombosis were recorded. RESULTS AND CONCLUSION: (1) The dominant and hidden blood loss in the groups B and C were significantly less than those in the group A (P < 0.05); the dominant blood loss showed no significant difference between groups B and C (P > 0.05); the group B exhibited a significantly less hidden blood loss compared with group C (P < 0.05). (2) The blood transfusion rate in the groups B and C was significantly lower than that in the group A (P < 0.05). (3) No pulmonary embolism or lower extremity deep venous embolism occurred during 3-month follow-up. (4) That is to say, tranexamic acid can obviously reduce perioperative blood loss and blood transfusion rate without pulmonary embolism or lower extremity deep venous thrombosis, and intravenous administration exerts better clinical effectiveness.

Objective:To investigate the expression of KCTD8 gene in breast ductal carcinoma and its correlation with clinical factors and prognosis.Methods:Immunohistochemistry technology(IHC)were employed to detect protein expression levels of KCTD8 in 27 pairs of breast ductal carci-noma and its paired adjacent tissues.Analyzing the correlation between changes in KCTD8 expres-sion of protein and clinical factors using statistical techniques.RNA expression and methylation data of breast cancer(including intraductal cancer)were analysed from TCGA database.Result:The pro-tein expression of KCTD8 gene in 27 pairs of breast ductal carcinoma tissues showed a decreasing trend compared to adjacent tissues(P＜0.05),and the decreased expression level of protein was cor-related with the tumor size of patients(P＜0.05).The analysis results of the TCGA database indicate that the expression and hypemethylation of KCTD 8 gene in breast cancer(including intraductal can-cer)tissues affected the prognosis of patients.Conclusion:The reduced protein expression level of KCTD8 gene in breast ductal carcinoma may be involved in the development and affect the prog-nosis of patients.

OBJECTIVETo analyze the trends of food consumption among Chinese residents aged from 18 to 59 years old in 9 provinces (autonomous region) from 1989 to 2006.

METHODSThe paper was based on data collected in 1991, 1993, 1997, 2000, 2004 and 2006 China Health and Nutrition Survey of Chinese residents of 24 h in three consecutive day dietary recall data. The healthy residents aged 18 - 59 years with twenty-four-hour dietary recall data were selected as study subjects. The sample sizes of these seven surveys were 5766, 7296, 7019, 7599, 8143, 7168 and 6827, respectively. The trends of their food consumption in each year were analyzed through Kruskal-wallis method.

RESULTSThe intake of cereals decreased significantly from (528.5 ± 192.9) g/d in 1989 to (427.7 ± 173.8) g/d in 2006 (χ(2) = 2833.13, P < 0.01). The minor variation of soybean food intake was observed. The average intake was (22.3 ± 39.4) g/d in 1989 and (18.9 ± 30.5) g/d in 2006 which was still at a low level. The trend of vegetables intake showed a small decrease. It was (374.5 ± 205.9) g/d in males and (346.4 ± 187.6) g/d in females in 2006, respectively. Both quantity and rate of fruits consumption showed an increase trend. Its consumption rate reached at 22.5% (741/3296) in males and 27.7% (1004/3619) in females in 2006, respectively. The average intake increased from (122.4 ± 126.9) g/d in 1989 to (228.5 ± 267.3) g/d in 2006 (χ(2) = 539.66, P < 0.01). At the same time, the daily intake of meat and egg showed a large increase, the average meat intake increased from (97.0 ± 111.5) g/d in males and (80.2 ± 97.0) g/d in females in 1989 to (141.5 ± 125.2) g/d in males and (118.4 ± 111.8) g/d in females in 2006, respectively. The oil consumption showed a significant increase. The average intake increased from (30.4 ± 37.9) g/d in 1989 to (42.8 ± 32.3) g/d in 2006 (χ(2) = 1646.94, P < 0.01).

CONCLUSIONSThere have been noticeable changes in the Chinese dietary pattern in the past 17 years. Some changes would be helpful for nutritional improvement in Chinese people, but it also caused some adverse effects on health because of improper food consumption.

OBJECTIVETo analyze the status and trend of dietary fiber intake and its food sources among Chinese residents aged 18 - 45 years old in 9 provinces (autonomous region), from 1989 to 2006.

METHODSTwenty-four-hour dietary recall data of three consecutive days from China Health and Nutrition Survey (1989, 1991, 1993, 1997, 2000, 2004 and 2006) were used. And the 18 - 45 years old subjects with complete information on dietary survey were included. The sample size of these 7 surveys were 5597, 5596, 5323, 5485, 5308, 4144 and 3889, respectively. The trends of dietary fiber intake and food sources by time and sex were studied.

RESULTSFrom 1989 to 2000, the total of daily dietary fiber intake of 18 - 45 years old healthy residents decreased from 15.1 g/d to 11.6 g/d, insoluble dietary fiber intake decreased from 22.6 g/d to 17.8 g/d. In villages, from 1989 to 2000, the insoluble dietary fiber intake decreased 5.1 g/d in males and 5.2 g/d in females(13.2, 11.8 g in 2000, respectively;18.3, 17.0 g in 1989, respectively). In 2006, the insoluble dietary intake was 12.6 g/d in males and 11.2 g/d in females in villages. In cities, from 1989 to 2006, the insoluble dietary fiber intake was 9.4 - 11.8 g/d in males and 8.3 - 10.8 g/d in females. The total dietary fiber intake was 15.7 - 17.6 g/d in males and 13.5 - 16.4 g/d in females. The difference of insoluble and total dietary fiber intake between city and village was decreasing. In 2006, 70.6% (8.4/11.9) insoluble dietary fiber came from vegetables ((4.1 ± 3.1) g/d), wheat flour and its products ((2.6 ± 3.6) g/d), rice and its products ((1.7 ± 1.3) g/d).

CONCLUSIONDietary fiber intake among Chinese aged 18 - 45 in 9 provinces (autonomous region) decreased from 1989 to 2006. Vegetables, wheat flour, rice and their products were the major food sources of insoluble dietary fiber.
