Objective To estimate the influence of abnormal glucose metabolism during pregnancy and family history of cardio-cerebrovascular disease and/or diabetes on umbilical C-peptide concentrations. Methods Chesed 85 pregnant women who had prenatal examination and their newborns as the subjects. Thirty-six newborns of mothers with gestational diabetes mellitus, impaired glucose tolerance or diabetes mellitus with pregnancy and 49 newborns of mothers with normal glucose tolerance were randomly chosed as the control group. All newborns were also classified according to whether their maternal grandparents had history of diabetes and/or cardio-cerebrovaacular disease. Therefore, there were four groups in this study: 25 newborns in group A were of diabetic mothers and positive family history, 11 newborns in group B were of diabetic mothers but negative family history, 9 newborns in group C were of mothers with normal glucose tolerance but positive family history, 40 newborns in group D were of mothers with normal glucose tolerance and negative family history. The blood samples of umbilical veins were collected at the time of delivery. Umbilical C-peptide levels of the four groups were measured by radioimmunonssay. Results The umbilical C-peptide concentrations of newborns in group A, B, C, D were (2.22±1.52), (1.44±0.63), (1.13± 0.34), (1.31±0.69) μg/L respectively, the umbilical C-peptide concentrations of newborns in group A were elevated compared to those of other three groups (F=5.11, P=0.003), and there were no significant differences in C-peptide levels of newborns between the three groups (group B vs C P=0.499, group B vs D P=0.694, group C vs D P=0.642). Conclusion Special attention should be given to newborns of diabetic mothers and whose maternal grandparents have history of diabetes and/or cardio-cerebrovascular disease.

A rapid thin flat gel isoelectric focusing method followed by ultrasensitive silver staining was developed for the determination of apo E phenotypes. Using this method, apo E phenotypes and allele frequencies in 63 normal individuals, 70 patients with hyperlipidemia and 11 patients with familial hypereholesterolemia (FH) in Nanjing were examined. TC, TG, HDL-C, LDL-C, VLDL-C, VLDL-TG in these cases were also measured. The relative frequency of the ?4 allele is significantly lower while the relative frequency of the ?3 allele is higher in this group than in the Caucasian group. Plasma TG, VLDL-TG, VLDL-C and VLDL-C/VLDL-TG are higher in the apo E3/2 phenotype, and lower in the apo E4/3 phenotype, wherea splasma TC, LDL-C levels are lower in the apo-E3/2 and higher in the apo E4/3 phenotype. It implies that the ?2 allele has the action of increasing TG-rich lipoprotein particles and reducing ch-rich lipoproteins in plasma, while the ?4 allele has an effect opposite to that of the ?2 allele. The highest prevalence of the ?4 allele was associated with type Ⅱb hyperlipoproteinemia (HLP), while that of the ?2 allele was associated with type Ⅲ-HLP. The frequency of ?2, ?4 are higher in FH patients as compared with normal subjects.

Objective To evaluate the effect of detailed disease management model in community management of hyperuricemic patients.Methods One hundred and fifty patients with primary hyperuricemia were randomly divided into detailed management group and conventional group from April to June 2012,patients in two groups were managed by different models for 1 year.The weight,height,biochemical indexes including blood uric acid and serum lipids were measured and a questionnaire survey was conducted with the items of disease awareness score,smoking,drinking,diet,standard treatment,satisfaction of treatment etc.before and after management.Results One hundred and thirty six patients completed the study including 68 in detailed management group and 68 in conventional group.After one year management,the blood uric acid,triglyceride,low density lipoprotein (all P ＜ 0.01) were statistically lower than baseline in detailed management group,while there were no statistical differences of these indexes in conventional group (P ＞ 0.05).The disease awareness score increased from (65.4 ±5.4) to (82.7±4.2) (Z=-10.2,P＜ 0.01),high purine diet rate fell from 47.1％ to 7.4％ (x2 =33.6,P ＜ 0.01),the standard treatment rates increased from 10.3％ to 85.3％ (x2 =76.6,P ＜0.01),treatment satisfaction rate increased from 51.5％ to 88.2％ (x2 =21.8,P ＜0.01) in detailed management group.In detailed management group,the blood uric acid (Z =-7.4,P ＜ 0.01),total cholesterol (Z =-0.01,P ＜ 0.01),triglyceride (Z =-2.4,P ＜ 0.01) and low density lipoprotein (Z =-3.2,P =0.03) and high purine diet rate were lower (x2 =27.1,P ＜ 0.01),the standard treatment rate (x2 =70.6,P ＜ 0.01) and treatment satisfaction rate were higher (x2 =5.6,P =0.02) than those in conventional group after 1 year management.Conclusion Detailed disease management is an applicable and effective model for community management of hyperuricemic patients.

Objective:To evaluate whether Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection has posi-tive effects on the prevention and treatment of radiation-induced lung injury. The basic function and mechanism of Salviae Miltiorrhi-zae Liguspyragine Hydrochloride and Glucose Injection were also investigated. Methods:A total of 70 adult male rats weighing about 200 g were selected and divided into seven groups. These groups were as follows:1) normal control group (N):rats were injected with 1 ml of normal saline per day;2) single medicine treatment group (D):rats were administered with 1 ml of Salviae Miltiorrhizae Ligus-pyragine Hydrochloride and Glucose Injection per day;3) single irradiation group (Z):rats were exposed to 20 Gy single whole-chest ir-radiation and injected with 1 ml of normal saline per day;4) irradiation with 10 Gy and medicine treatment group (Z10):rats were ex-posed to 10 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day; 5) irradiation with 15 Gy and medicine treatment group (Z15): rats were exposed to 15 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;6) irradiation with 20 Gy and medicine treatment group (Z20a):rats were exposed to 20 Gy single whole-chest irradiation for four weeks, and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day;and 7) irradia-tion with 20 Gy and medicine treatment group (Z20b):rats were exposed to 20 Gy single whole-chest irradiation and administered with 1 ml of Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection per day. Two rats were selected and sacrificed at the end of two, four, six, eight, and ten weeks of irradiation. Samples of blood and lung tissues in rats were obtained. Results:In the group with single irradiation, the tumor necrosis factor-α (TNF-α) and transforming growth factor-β (TGF-β) levels in plasma of rats were higher than those in the other groups. In the group with irradiation and medicine treatment, the TNF-αand TGF-βlevels in plasma were higher than those in the normal control group and single medicine treatment group. In the group with single irradiation for four weeks,some petechial hemorrhages on the surface of the lung were visible to the naked eye. In the groups with medicine treatment, the petechi-al hemorrhages on the surface of the lung visibly reduced. According to the pathological mechanism of lung tissues, the groups with Sal-viae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection exhibited less inflammation than the single irradiation group. Ir-radiation at 20 Gy for four weeks followed by a daily abdominal injection was slightly better than single irradiation, but the effects were not obvious. Conclusion: Salviae Miltiorrhizae Liguspyragine Hydrochloride and Glucose Injection could prevent the occurrence of lung injury by reducing the TNF-αand TGF-βlevels in plasma. After the occurrence of radiation-induced pneumonitis, the application of medicine could not decrease the symptoms.

Objective To evaluate the left ventricular function in patients with different extents of coronary stenosis by the left ventricular pressure volume loop Methods In 65 patients who were undergoing coronary angiography and left ventriculography examinations, materials of clinical and cardiac catheter examinations were collected In right anterior oblique 30 degrees the left ventriculography was progressed The pressure curves of the left ventricle and the aorta were recorded continuously and volumes of the left ventricles were measured with the dot tracing method Pressure volume loop was set up and ventricular energy indexes embodied by the pressure volume loop were measured and calculated Results In normal group, pressure volume loop was located in the left and lower portion of the coordinate system Along with the levels of the coronary stenosis becoming more severe, pressure volume loops moved to the right and upper portion of the coordinate system Little changes occurred in ejection fraction except that there was a decreasing in patients with lesions of three branches; Stroke work showed no obvious changes; Filling energy became larger; Total energy increased obviously in both groups with lesions of double branches and three branches; End systolic energy increased gradually while energy efficiency decreased gradually Conclusion The ventricular pressure volume loop can be obtained in routine ventriculography which can reflect many indexes of ventricular function quantitatively The ventricular energy indexes change correspondingly with coronary artery lesions and may be useful to assess ventricular function in patients with different levels of coronary stenosis

Aim: To study the effects of chitosan on hepatic lipids in fatty liver rats. Methods: The rats given a low does of carbon tetrachloride (CCl4) and fed a high-fat diet were treated with chitosan in different doses. Results: When rats were treated with mid dose of chitosan (4mg? g~-1?d~-1), the contents of triglycerde (TG). total cholesterol (TC) in liver decreased significantly, the level of mitochondria malonal-dialdehyde (MDA) was markedly attenuated and the mitochondria membrane fluidity was restored, which compared with model group. Conclusion: Chitosan may decrease the hepatic lipids by reduced the lipid peroxida- tion and restored mitochondria membrane fluidity to improve the mitochondrial beta-oxida- tion.

Objective To evaluate the possibility and efficiency of early lung cancer screening using low-dose spiral CT,and to investigate the effects of prognosis of lung cancer. Methods 3005 routine chests check-up were carried on the low-dose prospect research of the SHIMADZU 7800 TX spiral CT. According to the result by tracing and long-term CT follow-up based on the baseline screening, biopsy or surgical excisions were recommended in "malignant change" or enlarged nodules. Two doctors separately interpreted all the images blindly.Results 29.9 rate of nodules in all of cases were detected. Smoking group was 1.3 times incidence of non-smoking. A whole incidence of lung cancer was 1.2, including 2.9 in people at high risk of lung cancer and 0.9 in common people. The sensitivity and specificity of lung cancer screening using low-dose spiral CT were 82.9 and 88.8 respectively, and the diagnostic accuracy of lung cancer screening in diameter of nodules less than 10 mm was high than in ones more than 10 mm. Histologically, 33 non-small cell lung cancers (19 stageⅠ, 10 stageⅡand 4 stageⅢ), 2 small cell lung cancers and 1 scar carcinoma were proved based on baseline screening by biopsy or surgery. By the end of 2007, the average survival for clinical stageⅠlung cancer was more than 4 years, clinical stageⅡwas 2～3 years and clinical stageⅢ was 1～2 years. Conclusion Low-dose spiral CT is of high sensitive and specificity in detecting early lung cancer. Preliminary screening study indicates that low-dose spiral CT can greatly improve the likelihood of detection for early lung cancer and situation of survival.

Objective To observe and analyze the CT and MR imaging of the structures in the region of the jugular foramen (JF) on the base of thin-slice anatomic study. Methods Having been scanned by multislice CT and 1.5T MR scanner, two formalin-preserved adult cadavers were dissected into 1.0 mm thickness contiguous sections in transverse plane. Twenty cases without skull base and nasopharyngeal history received routine and post-contrast CT examinations with spiral and HQ mode. Twenty healthy volunteers received MR scanning, including SE T 1WI, FSE T 2WI, and 3D RF-FAST (3D Radio-Frequency Fourier Acquired Steady-State) sequences. Results JF region was divided into three levels, which included inner aperture, the jugular cavity, and the outer aperture. At the entrance of JF, there were glossopharyngeal canal and vagal canal, which wrapped the Ⅸ nerve and Ⅹ and Ⅺ nerves, respectively. CT images could display these canals in 20 cases (100%). Furthermore, the Ⅸ, Ⅹ, and Ⅺ nerves could be identified on different MR sequences. 17 cases (85%) were displayed on 3D RF-FAST, 14 cases (70%) on SE T 1WI, and 10 cases (50%) on FSE T 2WI, respectively. From the anterior to the posterior compartment within the JF cavity, the structures ranged as follows: the Ⅸ nerve, the inferior petrosal sinus, the Ⅹ and Ⅺ nerves, and the jugular bulb. These neuro-vessel structures could not be distinguished on CT, SE T 1WI, and FSE T 2WI images, except for 3D RF-FAST (16 cases, 80%). The outer aperture of JF was adjacent to the hypoglossal canal. The shape of JF outer aperture could be evaluated on CT images. On the oblique plane, which was parallel to the hypoglossal canal, the posterior cranial nerves could be detected to enter/exit the skull through the JF and hypoglossal canal separately. Conclusion The complement of CT and MR imaging would be helpful to distinguish the structures in the region of JF.

Objective To study the relationship between M. Genitalium and nongonococcal, non-chlamydial mucopurulent cervicitis. Methods A total of 226 patients with nongonococcal, nonchlamydial mu copurulent cervicitis and 118 healthy female volunteers were recruited in this study. Cervical samples were collected and M.genitalium was detected by PCR amplification of 16s rRNA and Pa genes. Information about socio-demographic characteristics, medical history, and sexual behaviors was gathered by questionnaire from both populations. Results The prevalence of M. Genitalium infection was 11.06% (25/226) in patients with mucpurulent cervicitis, 0,85% (1/118) in the healthy controls; the difference was significant between the two groups (x2 = 11.58, P < 0.001). Single variant analysis on the 226 patients showed that the preva-lence of M. Genitalium infection was 27.78%, 16.36%, 18.28% and 14.12% in patients with ectopic pregnancy history, cervical inflammation, pelvic organ tenderness, 10 or more polymorphonuclear leukocytes (PMNs)per oil immersion field in cervical discharge, respectively, significantly higher than that in patients without ectopic pregnancy history, cervical inflammation or pelvic organ tenderness, and those with less than 10 PMNs per oil immersion field in cervical discharge (9.62%, 6.03%, 6.02% and 1.79%, all P < 0.05). M.genitalium infection was also related to multiple sex partners and the presence of mucopurulent secretion in cervix (P < 0.001). Conclusion The prevalence of M.genitalium infection is higher in patients with non-gonococcal, nonchlamydial mucopurulent cervicitis attending STD clinic than that in normal population.
