Objective To explore memory function affected by chronic insomnia. Methods Fiftyfive patients with primary insomnia (PI), 119 patients with comorbidity of depression and insomnia (CDI)and 50 normal individuals were enrolled. Objective memories, including spatial working memory, spatial reference memory, objective working memory and object reference memory, were detected by nine boxes maze, and subjective memory was assessed by themselves on a 5-point scale ranging from 0 ( extremely severe problem) to 4 (no problem). Results Compared to the controls, the self-evaluated memory ( 1( 1,2 ) ) was worse in the mild PI patients, and the spatial working memory ( 6 ( 2. 5,11 ) ) was also worse in the severe PI patients( ×2 = 4. 526,3. 529, both P ＜ 0. 01 ). For the CDI, the self-evaluated memory ( 2 ( 1,2) ) and spatial working memory (6(3,10)) were worse in the mild patients(×2 =5. 803,4. 155 ,both P ＜0. 01 ). However, the object ( 0. 5 (0,1) ) and spatial reference ( 1.5 ( 1, 3 ) ) memories were also worse in the severe patients ( ×2 =2. 641,3. 955 ,both P ＜0. 01 ). Conclusions PI damages subjective memory and the severe PI also damages spatial working memory. CDI damages various memory functions, especially in severe CDI patients, including subjective memory, object reference memory, spatial reference memory and spatial working memory.

ObjectiveTo explore alterations of serum levels and clinical significance of corticotropin releasing hormone (CRH), thyrotropin releasing hormone (TRH) and gonadotropin releasing hormone (GnRH) in patients with fibromyalgia (FM). MethodsA total of 55 subjects participated in this study: 29 healthy volunteers and 26 patients with FM recruited from Department of Neurology, the First Affiliated Hospital of Anhui Medical University from June 2009 to October 2010.The depression rate was assessed by Hamilton Depression Rating Scale-17. ELISA was used for the detection of the serum levels of CRH, TRH and GnRH.Normal distribution quantitative data were described by the (-x) ± s and tested by independent sample t-test. Non-normal quantitative data were described by interquartile range and tested by independent Mann-Whitney.The diagnostic specificity and sensitivity of 3 kinds of hormones test were analyzed by receiver operator characteristic ( ROC ) curve, and the Spearman correlation was used for analysis of hormone levels and age, gender, tenderness, pain degree and depression severity.Results Compared with the control (70. 0(48.7,78.0) ng/L), the fibromyalgia patients had obviously increased CRH (271.9 (210.9,326.5) rg/L, x2 =6.408, P＜0. 01) , and significantly higher TRH ((82.7 ±6. 9 ) ng/L vs ( 87. 2 ± 6. 8 ) ng/L, t = 2. 560, P ＜ 0. 05, respectively) and GnRH ( ( 18. 2 ± 0. 9 ) ng/L vs ( 19. 9 ± 1.6)ng/L,t =5. 324, P ＜0. 01, respectively). The serum concentrations of the CRH, TRH and GnRH were positively correlated with pain intensity and numbers of tenderness respectively, and those of the CRH and GnRH were positively correlated with depressive degree either. The areas under the ROC curve in the CRH, TRH and GnRH, evaluating the sensitivity and specificity for diagnosis of fibromyalgia, were respectively 1. 000, 0. 684 and 0. 854. ConclusionsThe FM patients had an increased secretion of CRH,TRH and GnRH. CRH might serve as the adjunctive criteria for the diagnosis of FM.

Conclusion RAWM task is excellent spatial learning and memory task and is sensitive to measure the age-related decline of learning and memory ability in C57BL/6 mice.

BACKGROUND: Vascular complications usually occur in diseases related to obesity such as primary hypertension or diabetes. Treating obesity with the method of promoting blood circulation to remove blood stasis gains a curative effect, so we presume that obesity may be correlated to blood stasis syndrome.OBJECTIVE: Analyzing the relationship between leptin(Lep) and insulinmetabolism of sugar and fat,endothelin(ET),blood pressure,body mass index(BMI), etc. Comparison of the differences in Lep and BMI between the blood stasis syndrome group and the non-blood stasis syndrome group was conducted to explore the correlation between obesity and the blood stasis syndrome.DESIGN: An observatory and controlled study based on patients with hypertension or diabetes.SETTING: Wards of the department of dardiovascular dedicine and the department of dndocrinology of a university of traditional Chinese medicine.PARTICIPANTS: All the patients in the present study were hospitalized at the Department of Internal Medicine of the Second Affiliated Hospital(Jinan City, Shangdong Province) of Shandong University of Traditional Chinese Medicine from September 2000 to January 2001.Among them, 126 cases with hypertension were at the Department of Cardiovascular Medicine, and 133 cases with type 2 diabetes were at the Department of Endocrinology. Inclusion criteria: ① The diagnosis of diabetes followed the diagnostic criteria for diabetes that was formulated by the WHO in 1980; ② The diagnosis of hypertension followed the diagnostic criteria in"China' s Guidebook for Hypertension Prevention and Treatment." The patients were aged between 45-76 years. Exclusion criteria: ① Secondary hypertension,diabetics; ②Complicated with severe diseases; ③ Complicated with severe disfunction of the heart,lung,liver, kidney or severe primary diseases in hematopoietic system; ④ Patients with mental disorder or pregnant women or in the state of lactation; ⑤ Patients aged <45'years old or>76 years old; ⑥ Patients who refused to participant in the study. Eighty-four cases with primary hypertension and 85 diabetics met the inclusion criteria, with a total of 169 cases including 73 male cases and 96 female cases. The cases were divided into blood stasis syndrome group and non-blood stasis syndrome group according to the clinical symptoms. There were 23 male cases and 37 female cases in the blood stasis syndrome group.METHODS: Drawing vein blood at the state of empty stomach for making plasma and serum. ET was detected with the radioimmuoassay(RIA) kit of ET by the method of RIA(the Arithmometer of Amma5500γ) . Lep and Ins were detected with the radioimmuoassay(RIA) kit of Lep and the radioimmuoassay(RIA) kit of Isu. The fasting blood sugar, total cholesterol(TC),triamid-glycerin(TG), high dense lipoprotein-cholesterol(HDL) and low dense lipoprrotein-cholesterol(LDL) were detected by the full-automatic bio-chemical analytical instrument of AMS-SaBa/8.MAIN OUTCOME MEASURES: Comparing the difference of Lep,Ins,ET between different diseases,syndromes; analyzing the relationship between Lep and Ins,BMI,blood sugar,blood lipid,blood pressure,etc.RESULTS: The detectable rate of the blood stasis syndrome in the diabetes group was higher than that in the hypertension group (P<0.05) . The ET density,Lep density,BMI,the percentage of fat of the blood stasis syndrome group were higher than those of the non- blood stasis syndrome group (P<0.05 ). The Ins density of the blood stasis syndrome group was lower than that of the non-blood stasis syndrome group(P<0.01 ). There was a positive correlation between Lep and BMI,the percentage of fat,ET,systolic pressure (SP),pulse pressure(PP) (P<0.05 or P<0. 01).CONCLUSION: There was a positive correlation between obesity and the blood stasis syndrome. Lep of patients with type 2 diabetes or hypertension was positively correlated to BMI,the percentage of fat and the level of ET.

Objective To investigate the correlation between resistin,adiponectin and the blood stasis syndrome in diabetic and primary hypertension patients.Method The primary hypertension and diabetes patients were drawn vein blood to make plasma and serum.Enzyme linked immunosorbent assay(ELISA) method was used in checking serum adiponectin and resistin.Radioimmuoassay method was applied in checking serum insulin,leptin,ET and tumor necrosis factor(TNF).The fasting blood sugar,total cholesterol(TC),triamid-glycerin(TG),high dense lipoprotein-cholesterol(HDL) and low dense lipoprotein-cholesterol(LDL) were detected by the chemi-enzymic method.The relation between the indexes and blood stasis syndrome was analyzed by SAS9.1 for windows.Results The detectable rate of the blood stasis syndrome in the diabetic patients was 0.423,while 0.246 in the primary hypertension patients.The difference was significant in statistics.Incidence of blood stasis syndrome increased with the course of illness.Compared with the non-blood stasis syndrome group,the content of leptin,ET and TNF in the blood stasis syndrome group significantly raised,but the content of adiponectin and insulin diminished.The content of resistin did not have obviously change.Compared with the primary hypertension patients,the level of leptin,adiponectin,resistin,insulin in the diabetic patients raised,but there wasn't significant difference in the level of ET and TNF.Conclusions There is negative correlation between adiponectin and the blood stasis syndrome.The link between obesity and the blood stasis syndrome may be through fat factor regulating vasoactive factor.The blood stasis syndrome caused by obesity maybe have nothing to do with the consistency of resistin.

The authors have studied the changes in the concentration of glutathione of the red blood cell (RBC-GSH) and plasma malondialdehyde (MDA) in 54 patients with acute brain stroke. The results indicated that the concentration of RBC-GSH reduced obviously and that of plasma MDA increased markedly within 72 hours after illness. However, there is no obvious difference between the cases of hemorrhagic cerebrovascular diseases and cerebral infarction group. The RBC-GSH level rised again in the 7th day, while the plasma MDA still remained higher level, they were normal during the convalescent period. The pathological basis of the change may be the response of the free radicals in human body.

No obvious difference was observed in clinical effect between two groups. Conclusion: Naofuqing Capsules possesses a definite therapeutic effect for senile dementia.

Objective To investigate the association between the plasma level of fibrinogen and carotid atherosclerosis(CAS)in patients with ischemic cerebrevascddar disease(ICVD),and the effects intensity of different risk factors on CAS.Methods Carotid intima-media thickness(IMT)was measured by color Doppler uhrasonography in 840 patients with ICVD,including cerebral infarction(ci),transient ischemic attack and insufficient blood-supply of vertebral-basilar artery.According to the results of uhrasonography,the patients were divided into four groups:normal(IMT≤0.9 mm),arterial sclerosis (0.9 mm1.5 mm)and stenosis(stenosis of lumina≥30%).The plasma fibrinogen and other biochemical markers were also detected.The history of hypertension,diabetes,hyperlipemia,smoking,drinking were recorded,and the blood pressure was measured.Results The level of fibrinogen was the highest((3.91±1.05)g/L)in the patients with CI,the difference was significant compared to the patients with TIA((3.45±0.81)S/L,X2=62.812,P<0.01),and so was the prevalence of CAS(77.0%),there was significant difference compared to the patients with TIA(61.8%,X2=9.000,P<0.01).The rate of CAS increased gradually with the quartiles of the fibrinogen(the odds ratios in the 2nd,3rd and 4th quartiles(3.16-3.72 g/L,3.72-4.39 g/L and>4.39 g/L)were 1.80,3.36 and 3.38 respectively,all P≤0.01).There were significant differences of age,fibrinogen,systolic blood pressure,hyperglycaemia and history of diabetes and hypertension between the normal-carotid group and three CAS groups.Multiple logistic regression showed that only the age,fibrinogen and systolic blood pressure significandy influenced on the CAS with the highest risk factor being the fibrinogen.Conclusions In the patients with ICVD,the elevated plasma fibrinogen Was significantly correlated with CAS,and misht play more important role than other traditional risk factors.

Objective To summarize the distribution of departments,conditions of diagnosis and treatment of the syphilis patients in the general hospitals,and thus to improve the level of diagnosis and treatment.Methods A retrospective analysis of epidemiology and clinical data of 282 cases with syphilis in recent 5 years were conducted. Results The ratio of male to female was about 1:1.9.Female showed a high incidence in the 21 -50 years old,aver-age (41.68 ±0.96)years old,but for male in the 41 -70 years old,average (53.25 ±1.59)years old.The cases combined with other infectious diseases accounted to 22.0 % (62/282).The cases from the department of obstetrics and gynecology were the most (106 cases),followed by surgery (86 cases)and internal medicine (49 cases).Only 23 cases showed the clinical manifestations of syphilis in the 79 cases,which must be treated.The test rate of TRUST was only 39.0% (110/282).Furthermore,it was very low for the rate of treatment and standard treatment. Conclusion Syphilis is the most in department of obstetrics and gynecology in general hospital,and it is also com-mon in the surgery and internal medicine.The most prominent problems are that the non-special doctors had weak awareness for definite diagnosis of syphilis,and the low rate of treatment and standard treatment.
