Gallstone disease is highly prevalent in clinic,particularly in women and some specific ethnic groups.The formation of water-insoluble cholesterol crystals is due to a misbalance between the three major lipids present in the bile:cholesterol,bile salts,and phospholipids.Many proteins implicated in biliary lipid secretion in the liver are regulated by several transcription factors,including nuclear receptors LXR and FXR.Human and murine genetic,pathophysiological evidence is consistent with the relevance of these nuclear receptors in gallstone formation.In addition,there is emerging data that also suggests a role for estrogen receptor ESR1 in abnormal cholesterol metabolism leading to gallstone disease.A better comprehension of the role of nuclear receptor function in gallstone formation may help doctors to design new and more effective therapeutic strategies for this highly prevalent disease condition.

Addition of oxygen-vectors(n-dodecane,n-hexane,hydrogen peroxide) to fermentation medium was recognized as a method of enhancing oxygen transfer and promoting lycopene yield by Blakeslea trispora fermentation.Higher lycopene production was observed in shake flask containing 1%(v/v) n-hexane,n-dodecane and 150 L/100mL hydrogen peroxide as compared to shake flasks without oxygen-vectors.The result of assays indicated that when oxygen-vectors (n-dodecane,n-hexane,1%,v/v) and hydrogen peroxide(50 L/100mL) were added to the 0-day and 1-day old culture of Blakeslea trispora the production of lycopene were 25.32%,72.84% and 40.35% higher than those without oxygen-vectors addition respectively.The production of lycopene increased 114.83% when n-dodecane and surface active agents were used at the same time.

Objectives　To investigate the relationship between homocysteine (Hcy), folic acid, vitamin B12(VitB12),lipids and the carotid artery atherosclerosis(CAAs) and the significance of their levels in predicting cardiac and cerebral vascular events of older patients. Methods　Both sides of the common carotid artery and internal carotid artery were measured by B-mode ultrasound in 74 examinees in A, B, C, and D groups and a control group. With fasting serum, cholesterol, triglyceriade, apolipoprotein AI(Apo AI), apolipoprotein B (Apo B), lipoprotein (a) ［Lp(a)］, creatinine, glucose, folic acid, Vit B12 and Hcy were detected. Results　When carotid artery atherosclerosis became severer, serum Hcy was higher. The levels of the control and A, B, C, D groups were (10.2±3.6) μmol/L, (11.5±4.4) μmol/L, (17.9±4.5) μmol/L, (24.7±10.3) μmol/L, and (41.4±22.3) μmol/L respectively. SNK test showed a significant difference between D and other groups (P>0.05). Folic acid and Vit B12 were negatively correlated with the severity of carotid artery atherosclerosis, but only A and D groups showed statistical significance. Spearman correlation coefficient showed that serum Hcy had significant negative correlation with folic acid and Apo AI(P=0.035 and P=0.000).Multiple linear regression analysis between CAAs and various risk factors showed Apo AI had negative correlation, but Apo B, Lp(a) and Hcy had positive correlation with CAAs, especially Hcy(P=0.009).Conclusion　Hyperhomocysteinaemia is an important risk factor of artery atherosclerosis and the degree of CAAs is highly correlated with Hcy concentration. Hcy, Apo AⅠ,Apo B, Lp(a) are sensitive and reliable indexes for evaluating and predicting CAAs.

Objective To investigate the clinical efficacy and safety of combined acupuncture and medicine in treating polycystic ovarian syndrome infertility.Methods Ninety patients with polycystic ovarian syndrome infertility were randomly allocated to treatment and control groups, 45 cases each. The control group received oral administration of clomifene citrate tablets plus muscular injection of chorionic gonadotropin and the treatment group, electroacupuncture in addition. The ovulation rates, pregnancy rates, incidences of ovarian hyperstimulation syndrome (OHSS), ectopic pregnancy rates and early miscarriage rates were compared between the two groups of patients. Results The ovulation rate and the pregnancy rate were 97.8 % and 37.8%, respectively, in the treatment group and 75.6% and 17.8%, respectively, in the control group; there was a statistically significant difference between the two groups (P<0.05). Of 17 pregnant patients in the treatment group, 2 had early miscarriage, accounting for 11.8% and none had ectopic pregnancy, accounting for 0.0%. Of 8 pregnant patients in the control group, 4 had early miscarriage, accounting for 50.0% and none had ectopic pregnancy, accounting for 0.0%. The incidence of OHSS was 4.4% in the treatment group and 6.7% in the control group; there was no statistically significant difference between the two groups (P>0.05).Conclusions Combined use of acupuncture and medicine can increase the ovulation rate and the pregnancy rate in patients with polycystic ovarian syndrome infertility. It does not significantly cause ovarian hyperstimulation and ectopic pregnancy and may decrease the early miscarriage rate.

OBJECTIVE To observe bacterial distribution and drug resistance in Ningxia.METHODS The patients with nosocomial infection mornitored by Ningxia Hui Autonomous Region Nosocomial Infection Surveillance System from Jan 2003 to Dec 2007 were analyzed and summarized.RESULTS Amomg 3276 isolates,1752 strains(53.48%) were Gram-negative bacilli,1471 strains(44.9%) were Gram-positive cocci and,53(1.62%) fungi.The most common pathogens were Escherichia coli(909),Staphylococcus aureus(509),S.epidermidis(260),Enterococcus faecalis(258),and Pseudomonas aeruginosa(206).Most of them were multidrug resistant.Most strains of Gram-negative bacilli were highly susceptible to imipenem,while most strains of Gram-positive cocci were highly susceptible to vancomycin.CONCLUSIONS Most pathogens of nosocomial infection are multidrug resistant,the resistance detection of bacteria has an important significance to clinical treatment and infection control.

Objective:To confirm the correlations between the soma ofthe traditional Chinese Medicine and the objective index about Homeostasis model assessment-Insulin Resistance index(HOMA-IR)and the function about beta Cell ofislet(HOMA-?)with Impaired glucose regulation(IGR),to explore the basis for the syndrome ofthe traditional Chinese Medicine and insulin function.Methods:According from the epidemiological investigation,we had a Oral Glucose Tolerance Test and insulin releasing test to the 1 500 persons who came from downtown area、county、small towns、village,in accordance with the soma ofTCM,then investigate and analysis the correlations who meet the diagnosis ofIGR.Results:①In all 322 cases,each ratio ofthe group about signal soma、twice soma、three soma is 74.8%、19.5%、8.1%,Ahead somas are mild, deficiency ofQi, deficiency ofYang, deficiency ofQi and Yang,phlegmatic hygrosis.②The BMI ofmild group is higher than the deficiency ofQi,deficiency ofYang,deficiency ofQi and Yang group(P
