Objective To investigate the association of insulin dose with clinical factors of type 2 diabetes. Methods We reviewed the data of 214 type 2 diabetic patients who received insulin regimens.We compared the insulin dose and period at the targeted blood glucose levels among 6 groups according to different type of oral hypoglycemic agents. Results There existed statistically significant correlations of the glucose-targeted insulin dose with course,FPG,BMI,combination therapy with oral hypoglycemic agent(P<0.1,test level P=0.1).Merely metformin failure group took less insulin than the group admitted due to combination therapy failure (P=0.016, 0.53(0.35～0.62)U/kg and 0.63(0.51～0.75)U/kg respectively).The longest targeted period existed in the later. Relationship between the targeted bedtime insulin NPH dose and FPG level can be demonstrated by equation Y=0.255X+7.8. Conclusions The targeted insulin dose is influenced by synthetic factors. Patients admitted due to combination oral hypoglycemic drug failure have the maximal targeted insulin dose and the longest titration period. The final bedtime insulinNPH dose can be predicted by FPG level.

Objective To compare the diagnostic efficacy of the V/Q scan and CT pulmonary angiography (CTPA) for the detection of acute pulmonary embolism (PE) in elderly patients.Methods Fortyfour patients (age ≥60 years old) with suspected acute PE underwent V/Q scan and CTPA.The diagnosis of PE by V/Q scan was based on the criteria of prospective investigation of PE diagnosis (PIOPED) Ⅱ and the prospective investigative study of acute PE diagnosis (PISA-PED).The final diagnosis was made clinically.The sensitivities,specificities and accuracies of PIOPED Ⅱ,PISA-PED,CTPA and Wills score were calculated and compared using x2 and Fisher's exact tests.Kappa analysis was used to analyze the diagnostic accordance rate of PIOPED Ⅱ and PISA-PED.Results The sensitivities of PIOPED Ⅱ,PISA-PED and CTPA in the diagnosis of PE were 70.00％ (14/20),84.62％ (22/26) and 65.22％ (15/23),respectively (x2 =0.069-1.545,all P＞0.05).The sensitivity of Wills score was significantly lower (23.08％,3/13).The specificity of CTPA (93.75％,15/16) was significantly higher than those of PIOPED lⅡ and PISAPED (80.00％,12/15 and 61.11％,11/18,both P＜0.05).The accuracies of PIOPED Ⅱ,PISA-PED and CTPA were 74.29％ (26/35),75.00％ (33/44) and 76.92％ (30/39),respectively (x2 =0.005-0.070,all P＞0.05).The accuracy of Wills score was significantly lower (52.17％,12/23).The diagnostic accordance rate of PIOPED Ⅱ and PISA-PED criteria was 77.14％(27/35),Kappa=0.547,P＜0.05.Conclusion V/Q scan and CTPA have no significant difference for the diagnosis of PE in the elderly patients.

OBJECTIVE To assess the prevalence and analyze the influence factors of laryngopharyngeal reflux disease(LPRD) in the Fuzhou region, in order to provide a theoretical basis for the development of prevention and control measures for LPRD. METHODS A questionnaire survey in residents in Fuzhou by a random cluster sampling was carried out. Individual information, reflux symptom index(RSI) of Belafsky and risk factors were included. Patients more than 13 scores of RSI were defined as LPRD. Data were statistically analyzed. RESULTS A total of 4100 residents were investigated, 4063 of them were available. The prevalence of LPRD was 5.00%. Often eating too much, often drinking strong tea, menolipsis, rhinitis, tonsillitis were closely related to LPRD. CONCLUSION The prevalence of LPRD in Fuzhou region were closely related to many factors.

Objective To investigate the effect of persistent hypoglycemia on the cerebral oxidative stress and matrix metalloproteinase-2 (MMP-2) activity of newborn rats and to explore the potential mechanism of hypoglycemia-induced brain injury of newborn.MethodsSeven-day-old rats were injected insulin subcutaneously to induce persistent hypoglycemia.Cerebral cortex,hippocampus and thalamus were collected after 36 hours' observation and stored in -80 ℃.Glutathione (GSH)and glutathione disulfide (GSSG) were detected by commercial kit and GSSG/GSH was calculated.MMP-2 activity was detected by gelatin zymography. The data were analyzed by t test,one or two-wayanalysis of variance and Pearson correlation analysis.Six rats were set as the normal glucose group. ResultsThirty-six hours after induction of hypoglycemia, the cerebral GSSG and GSSG/GSH of hypoglycemic pups elevated about 1.5 times higher than those of control group [GSSG:(15.89 ± 5.46) vs (6.15 ± 3.42) mg/g protein,t =3.704,P =0.004; GSSG/GSH:(5.58± 1.79) ％ vs (2.79±1.76) ％,t =2.712,P=0.022].The GSSG and GSSG/GSH in thalamus of hypoglycemia were significantly higher than those of control [GSSG:(15.93 ± 5.75) mg/g protein vs (5.03±5.14)mg/g protein,P＜0.05; GSSG/GSH:(6.50±3.25) ％ vs (2.41±3.12) ％,P＜0.05],whereas there were no significant differences in the cortex ard hippocampus.The total MMP-2 activity of hypoglycemic animals (2.22±0.59) was significantly higher than that of control (1.21± 0.17)(t=4.064,P=0.002),and significant differences were found between the two groups in cortex (2.14 ± 0.5 vs 1.17± 0.27),hippocampus (2.31± 0.72 vs 1.22 ± 0.37) and thalamus (2.22±0.68 vs 1.24±0.18) with all P＜0.01].The activity of MMP-2 was positively related to GSSG (r=0.575,P=0.0002) and GSSG/GSH (r=0.484,P=0.0003).ConclusionsOxidative stress might play an important role in the persistent hypoglycemia induced brain injury of 7-day-old rat pups and thalamus might be most vulnerable to hypoglycemia.Hypoglycemia might also elevate MMP-2 activity which is positively related to GSSG level and GSSG/GSH of the brain.

Objective To investigate the correlation between the frustration tolerance and personality of medical college students and to discuss its promoting strategies.Methods Totally 460 college students were selected randomly.Questionnaire of frustration tolerance and scale of Eysenck personality inventory(EPQ) were used and the measurement data were compared with correlation analysis and regression analysis of SPSS 13.0.Results Correlation was significant between frustration tolerance (total score and 6 inducing factors) and personality (EPQ factors) of college students ； personality (EPQ factors)of students could predict their frustration tolerance and corresponding t value was -4.85,P ＜ 0.01 (psychoticism),6.93,P ＜ 0.01 (extraversion),-11.15,P ＜ 0.01 (neuroticism).Conclusions Personality of college students are greatly influenced by their frustration tolerance.Targeted anti-frustration ability training should be conducted according to the different personality characteristics.

Objective To investigate the effect of electro-acupuncture at Guanyuanshu, Xinshu, Neiguan points on cardiac function after acute myocardial ischemia in rabbits. Methods A total of 36 rabbits were randomly divided into a control group, a model group and a treatment group. Acute myocardial ischemia was induced with Jugular vein injection of pituitrin. At 10 min before modeling, 1 hour and 1 week after modeling, the levels of malondialdehyde (MDA) and creatine kinase(CK) were determined respectively, the cardiac function was assessed as the maximum rate of left ventricular pressure rise(dp/dtmax)and the peak left ventricular pressure (LVSP). Results After 1 week of treatment, the serum levels of CK and MDA in the treatment group reduced significantly(120.21±10.67 U/L, 21.35±2.04 mmol/L], compared to the model group (162.37±13.21 U/L, 30.13±2.75 mmol/L) (all P<0.05);the dp/dtmax and LVSP decreased percentage in the treatment group (20%±2.43%, 7.22%±0.97%) decrease significantly compared to the model group (31.5%± 4.14%, 12.19%±2.21%) (all P<0.05). Conclusion Electro-acupuncture of Guanyuanshu, Xinshu, Neiguan acupoints can significantly improve cardiac function after acute myocardial ischemia and protect against acute myocardial ischemia in rabbits.

Aim To study the effect of leuprorelin acetate microspheres (LE ms) on endometriosis in rats, and compare the efficacy of material drug (LE), domestic and imported LE ms (enanton). Methods Endometriosis was induced by endometrial implant in rats. Then the animals were treated with LE (20 ?g?kg -1 ?d -1 ? 28 d ,sc), enanton(20 ?g?kg -1 ?d -1 ,sc)and domestic LE ms ( 2,20,200 ?g?kg -1 ?d -1 ,sc). Results Implants in control group continued to grow, while those in groups treated with drugs shrinked significantly, and domestic LE ms could produce dose dependent inhibitory effect on the growth of endometrial implant in rats. Conclusion The domestic LE ms at the single dose of 20 ?g?kg -1 ?d -1 has the same effectiveness as enanton and routine injection with the same does of LE for 28 days.

ObjectiveTo investigate the expressions of folate receptor alpha (FOLR1) in 40 esophageal cancerous tissues and its relevance of ABO blood group.MethodsABO blood groups were analyzed in 40 patients.Immunohistochemistry (IHC) and real-time quantitative reverse transcription PCR detection were used to detect the expression of folate receptor in cancer and adjacent tissues.Results20％of esophageal cancer was suspected positive (+), 50％ of cancer adjacent tissue was suspected positive (+), 10％ were positive (+), the difference was statistically significant (x2 = 14.48, P ＜0.01).Real Time RT-PCR analysis showed FOLRI low expression in esophageal cancer and adjacent tissues, compared to normal esophageal mucosa, the differences were statistically significant (F1 =53.247, F2 = 116.500, P ＜0.01).ABO blood type and FOLRi in esophageal cancer patients were not significant correlated (P =0.647, P ＞0.05).ConclusionsFOLRI expression was decreased in the esophageal lesions compared with adjacent tissues.Detection of FOLRl expression level in esophageal cancerous tissues and the paired adjacent tissues was helpful for judging the extent of disease and guiding surgery treatment.The FOLRI expression level in esophageal carcinoma tissues had no relationship with ABO blood types.

Objective To develop a Chinese military psychosomatic health scale(CMPHS) and examine its reliability and validity. Methods Based upon the previous researches, the Scale was compiled according to open-ended inventory survey. The data was collected from 1050 subjects chosen by random cluster sampling. 60 of them were tested with the CPSHS at the same time, while 61 of them were retested with the CMPHS after two weeks. The reliability and validity were examined by exploratory factor analysis ( EFA) and correlation analysis. Results According to the factor analysis results, 11 factors were extracted, namely espiratory apparatus, alimentary system,skeletal and musculature,integument,regeneration and endocrine,nervous system, anxiety, depression, psy-choticism and family history. There were 91 items in the formal scale when one lie subscale was added. The correlation between subscales were 0. 103 ～ 0. 778 (P < 0. 01) , the correlation between subscales and total scale were 0.600 ～0.859(P<0.01). The test-retest correlation coefficients of total scale and subscales were 0.427 ～0.901 (P < 0.01); the Cronbach (α) coefficients were 0. 643 ～ 0. 935 (P < 0. 01) ; and the split-half correlation coefficients were 0. 349 ～ 0. 855 (P < 0. 01 ). The correlation coefficients were 0. 425 ～ 0. 979 (P < 0. 05 or 0. 01 ). Conclusion The Chinese military psychosomatic health scale has acceptable psychometrics properties on reliability and validity.
