objective To investigate the ability of insulin sensitivity index HOMA2-%S and secretion function index HOMA2-%B calculated by HOMA2,the new homeostasis model assessment,in clinical application. Methods Eighty female volunteers with polycystic ovary syndrome in Chongqing area [50 subjects with normal glucose tolerance(NGT group)and 30 subjects with impaired glucose regulation(IGR group)]were involved in this study.Thev underwent a 75 g oral glucose tolerance test(OGTF)and the Botnia clamp test. From the data of faming blood samples in OGTF,insulin sensitivity index HOMAI-ISI,secretion function index HOMAl-β and disposal index DI-HOMA1 were calculated by the old homeostasis model assessment(HOMA I),meanwhile insulin sensitivity index HOMA2-%S,secretion function index HOMA2-%B and disposal index(DI-HOMA2) were caleulated by the new homeostasis model assessment (HOMA2).Correlation coefficients between insulin sensitivity index and GIR (the glucose infusion rate at steady state of Botnia clamp test),and between insulin secretion function index and AIR(the acute insulin response in Botnia clamp test),were studied.Results The Pearson's linear correlation coefficient between HOMA2-%S and GIR(r=0.503),HOMA1-ISI and HOMA2-%S (r= 0.990).HOMA2-%B and AIR(r=0.382),HOMA1-B and HOMA2-%B(r=0.976) were all statistically significant(a11 P<0.01).The glucose disposal indexes calculated from the HOMA2 and HOMA1 of 1GR group were significantly lower than those from the NGT group(t=2.825,P<0.Ol;t=2.222,P<0.05). Conclusion The HOMA2 is a better model in evaluating the insulin sensitivity and secretion function and is recommended to be widely used in clinical evaluation.

Objective To develop a quality of life scale suitable for aphasic Chinese stroke patients by translating and evaluating the psychometric properties of the original 39-generic version of the Stroke and Aphasia Quality of Life scale (SAQOL-39g).Methods The SAQOL-39g was translated into Chinese and edited.The well edited and translated self-rated and non-self-rated scales were used to test 86 aphasia patients and their caretakers to evaluate the feasibility,internal consistency,test-retest reliability,content validity,and construct validity of the scale.Results The feasibility of the Chinese version of the SAQOL-39g scale was sufficient,with 97％ of the ques tionnaires completed.The average time taken to complete the self-report version was (21.4±4.37) minutes,with (13.25±5.61) minutes needed for the proxy version.The Cronbach's alpha values for the overall survey ranged from 0.879 to 0.950 and for the subdomains from 0.863 to 0943 for both forms,suggesting satisfactory internal reliability.The test-retest coefficients for the two forms ranged from 0.804 to 0.974 and from 0.861 to 0.987.A total of 3 common factors were extracted using factor analysis,and the cumulative contribution rate was 59.7％.The consistency between the self-reports and the proxy-reports was good.Conclusion The Chinese version of the SAQOL-39g scale demonstrates good feasibility,reliability and validity,and good consistency between the self-reported and proxy-reported versions.It seems suitable for assessing the quality of life of Chinese stroke patients with aphasia.

Objective To investigate the risk factors of mild cognitive impairment (MCI) in patients with type 2 dia-betes (T2DM), and the clinical evidence for the early diagnosis and treatment thereof. Methods A total of 217 T2DM pa-tients were divided into T2DM with MCI group (n=92) and T2DM with normal cognitive function(NMCI) group (n=125). Mon-treal cognitive assessment scale (MoCA) and activities of daily living scale (ADL) were used to assess the functional status in two groups of patients. The general clinical data and biochemical indicators were obtained and compared in two groups. Re-sults There were statistical differences in age, smoking history, education status, high sensitive C reactive protein (hs-CRP), coronary heart disease, hypertension, glycated hemoglobin A1c (HbA1c) and T2DM history between two groups. Re-sults of univariate logistic regression analysis showed that old age, longer course of T2DM, smoking history, higher hs-CRP and HbA1c, complicated with coronary heart disease and hypertension were risk factors for T2DM with MCI, while the higher education status was a protective factor. Multiple logistic regression analysis showed that old age and longer T 2DM history were risk factors, and the higher education was a beneficial factor for T2DM with MCI. Conclusion Many risk factors may play a part in T2DM with MCI. Early detection and prompting medical attention may help prevent and decrease the preva-lence of MCI in patients with T2DM.

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.

Due to its effect of systems regulation and promotion on body, Ginseng is always referred to be long-term used as a dietary supplement. But it was still unclear about its target of the tonic effects and also the side-effects long-term use may bring. Urine metabolomic method is suitable for long-term studies of pharmaco-dynamics, pharmacology and toxicology of traditional Chinese medicine because of its characteristics of non-invasive and monitoring the whole-body metabolism. This study was designed to detect the dynamic variation of rat urine metabolome along with a long-term administration of total ginsenosides using GC-TOF based metabolomic technology. Our result showed that either short-term or chronic administration of ginsenosides did not impact the rat urine metabolome significantly (as the PCA subgroup was not successful). By comparison, the short-term (1-3 w) dose of ginsenosides had the biggest metabolic influence including TCA cycle, catecholamines and neurotransmitter amino acids. Medium-term (6-10 w) dose had a gradually lower effect and long-term (27 w) dose almost had no effect. Our study indicates that both short and long-term administration of ginsenosides showed almost no obvious side-effect on the experimental animals.

AIDS antiviral therapy (ART) has achieved great success.Originaly,AIDS had been regarded as a fatal disease,but it has become a kind of infectious disease that could be cured and administrated.Global HIV / AIDS cases were still up to about 38 million,but more than half have been effectively treated.In addition to drug treatment,at present,some new technologies and new methods,such as genome editing,have also been involved in the treatment of AIDS,and in the humanized animal experiment has shown very good results.There is no doubt that AIDS will eventually be stopped its epidemic.However,with the continuous development of AIDS antiviral treatment,the most fundamental problem is that HIV latent library has become increasingly prominent one,whether molecular therapy and hybrid cure have being developed for AIDS treatment,there are still such problem existence.Great efforts shoud be made to continuously search for new markers of latent viral cells and to reduce the latent pool.In addition,despite the prevention and treatment of AIDS has made great achievements,but the world still produces nearly 6000 cases of HIV/AIDS every day.Therefore,the development of safe and effective vaccine,whether in the field of prevention,or in clinical treatment,has its positive significance.

Objective To investigate the prevalence of subclinical hypothyroidism and its relation to serum total cholesterol (TC),triglyceride (TG) levels and non-alcoholic fatty liver.Methods Serum levels of TC,TG, TSH,TT_3 and TT_4 were determined in 1 602 subjects which were divided into groups by sex and age (20-39,40- 59 and≥60 years).Fatty liver was diagnosed by type B ultrasonography.Restults ( 1 ) Prevalence of subclinical hypothyroidism was 6.6% in this population.(2) The mean levels of serum TC and TG in subclinical hypothyroidism group and normal group showed no significant difference ( both P＞0.05 ).(3) On the whole,the prevalences of subclinical hypothyroidism in hypercholesterolemia group and normal cholesterolemia group showed significant difference (P＜0.01 ).(4) In the three age groups of male and few.ale examinees,the prevalences of subclinical hypothyroidism in hypercholesterulemla group and normal cholesterolemia group showed no significant difference ( all P＞0.05 ).In the multiple regression analysis,TSH level was not related with raised TC level.(5) In the three age groups of male,there was no significant difference between the prevalences of subclinical hypothyroidism in hypertriglyceridemla group and normal triglyceridemia group ( all P＞0.05 ).In female,expect for the elderly group (＞60 years old ),the prevalence of subclinical hypothyroidism was higher in hypertriglyceridemia group than that in normal triglyceridemia.However,in the multiple regression analysis, increased TSH level was positively associated with increased serum TG level ( OR = 1.072,P=0.013 and OR = 1.102,P = 0.03 ).(6) The prevalence of subclinical hypothyroidism in non-alcobolic fatty liver group and normal group showed no significant difference ( P＞0.05 ).In the multiple regression analysis,TSH level was not the independent risk factor of non-alcoholic fatty liver (P＞0.05 ).Conclusion Subclinical hypothyroidism is not asseciated with serum TC level but positively associated with serum TG level.Subclinical hypothyroidism does not apparently increase the prevalence of non-alcoholic fatty liver.

OBJECTIVETo study the distribution and antibiotic resistance of the isolated pathogens from children with infectious diarrhea in Guangzhou.

METHODSThe fecal samples of 2 409 children with infectious diarrhea between January 2006 and December 2007 were collected and cultured. Pathogenic bacterium were isolated and identified by biochemical and serological methods. The antibiotic susceptibilities were tested by the Kirby-Bauer method.

RESULTSA total of 448 isolates of pathogenic bacterium (18.6%) were obtained, including Shigella (n=159), enteropathogenic Escherichia coli (n=141), Salmonella (n=76), Vibrion (n=11), fungus (n=41), and C jejuni (n=20). All of isolates of the three major pathogenic bacterium, Shigella, enteropathogenic Escherichia coli and Salmonella, were susceptible to imipenem and less than 10% of the isolates were resistant to the third generation cephalosporins and beta-lactamase inhibitors. However, the isolates showed a high resistance to ampicillin and sulfamethoxazole/trimethoprim (>75%).

CONCLUSIONSShigella, enteropathogenic Escherichia coli and Salmonella were major pathogenic bacterium of diarrhea in children from Guangzhou. The major isolates were susceptible to imipenem, the third generation cephalosporins and beta -lactamase inhibitors, but were resistant to ampicillin and sulfamethoxazole/trimethoprim.

OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.
