BACKGROUND: Hyperlipemia is one of the important risk factors of coronary atherosclerotic cardiopathy. Great attention has been paid on how to explain the correlation between blood lipid and coronary heart disease and the correlation of characteristics and level of blood lipid with coronary heart disease.OBJECTIVE: To probe into the correlation among the characteristics, the level of blood lipid and coronary heart disease in senile people.DESIGN: Case-control observation and stratified analysis.SETTING: Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA.PARTICIPANTS: Totally 105 inpatients were selected in coronary heart disease group, diagnosed as coronary heart disease, tallied with WHO Diagnostic Standard on Coronary Heart Diseases, in Second Cadre Ward of General Hospital of Shenyang Military Area Command of Chinese PLA from January 2001 to January 2002. Totally 99 inpatients, by checked, without coronary heart disease and cerebral vascular disorder were selected in the control in the same period.METHODS: 2 mL venous blood was collected in fasting in the morning and the serum was collected after centrifuged at 3 000 r/minute, for 5 minutes. Auto-biochemical analyzer and enzyme kit were used to determine cholesterol, triglycerin, high density lipoprotein cholesterol and low density lipoprotein cholesterol. Compared with the data in the control, the ranges of cholesterol, triglycerin and low density lipoprotein were calculated successively and divided by 10; at the class intervals of 0.53, 0. 39 and 0.29 mmonl/L, the frequency table was worked out. According to the frequency table, P25 (the 25th percentile), P50 (the 50th percentile), P75 (the 75th percentile) and P90 (the 90th percentile) of cholesterol, triglycerin and low density lipoprotein cholesterol were calculated successively. The stratified groups were divided based on P < 25, P25 to PS0, PS0 to P75, P75 to P90 and > P90, by which, the cases belonging to 5 groups were determined in coronary heart disease group and the control respectively. The exposure factor was determined by > P90, compared with other 4 groups, Menta-Haensecel method was used to calculate x2. If the exposure factor was related with coronary heart disease, the relevant coefficient and 95% confidence interval should be calculated. In accordance with the standards (Proposal on Prevention of Abnormal Blood Lipid and Targets of Abnormal Blood lipid on 2-grade Prevention of Coronary Heart Disease), the cases beyond the targets and morbidity were determined in two groups.MAIN OUTCOME MEASURES: Determination of blood lipid, abnormal cases and morbidity in two groups; cases beyond targets of blood lipid and morbidity; stratified comparisons of percentiles in two groups.RESULTS: According to intention measurement, 204 cases entered result and the control, there was no significant difference in cholesterol, triglycerin cases presented hypercholesterolemia, 34.3% cases hypertriglycerlipidemia and 11. 4% cases low density lipoprotein-hypercholesterolemia. It was indicated that the blood lipid was in the normal range among 64. 8% to 88.6% comparison between the cases with cholesterol ≥5.47 mmonl/L and the cases with cholesterol varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former was 2.98 times as high as the latter (x2 = 6.29, 95% confidence interval was 1.27 -6.98) . In the comparison between the cases with cholesterol ≥ 5.47 mmol/L and the cases with cholesterol varied from 4.64 to 5.05 mmol/L, the correlation with coronary Lipid for 2nd Prevention of Coronary Heart Disease, among the patients with coronary heart disease, cholesterol ≥ 4.68 mmonl/L in 54. 2% cases,triglycerin ≥ 1.70 mmol/L in 34. 3% cases and low density lipoprotein ≥ 2.6 mmol/L in 52. 3% cases.CONCLUSION: For senile patients with coronary heart disease, the satisfactory level of cholesterol is 3.85- 4.63 mmol/L. For those with cholesterol ≥ 5.47 mmol/L, compared with those varied from 3.85 to 4.63 mmol/L, the morbidity of coronary heart disease in the former is possibly 2.98 times as same as the latter(x2 = 6.29, 95% confidence interval was 1.27 - 6.98).

OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.
METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.
RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).
CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.
METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.
RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.
CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).
