tep immunochromatographic method accounted for 96.4%.Conclusion Both RT-PCR and step immuno chromatographic method can not be used as means of short-term therapeutic effect evaluation.

Influence of extraction process on the quality of Maxingshigan pills was studied. Guided by the amount of ephedrine in the extraction as determined by dual wavelength TL- C-scanning. Four different processes were compared. Result showed that Process C was the best among all.

Objective To investigate the change of neutrophil elastase and matrix metalloproteinase-9 in sepsis and determine significance in the early diagnosis and prognosis of multiple organ dysfunction syndrome.Methods The plasma levels of neutrophil elastase and matrix metalloproteinase-9 in 28 ICU patients with sepsis were examined by immunofluorescence.Results Compared with control group,the levels of NE and MMP-9 were significantly higher on the day of the diagnosis of sepsis(P

Objective To compare the karyote counting and classification results of Sysmex XE-5000 automatic blood analyzer (XE-5000) and manual method in special body fluids .Methods 100 cases of special body fluid specimens (including cerebrospinal fluid and serous cavity effusion) were analyzed ,and the the karyote counting and classification were respectively detected by XE-5000 and the traditional manual method of microscope .Results When the karyote counts were 31-1 000/μL ,there was no signifi-cant difference between XE-5000 and manual method (P>0 .05) .And the karyote counting and classification results of XE-5000 correlated with those of manual method (r=0 .981 ,0 .991 ,P<0 .05) .Conclusion When the karyote counts are 31-1 000/μL ,XE-5000 has good accuracy and high precision in karyote detection in special body fluids .

ObjectiveTo investigate the clinical features of Chinese dysgraphia and then probe into its mechanisms in a patient with semantic dementia(SD).MethodsThe patient with SD finished the writing part of the Aphasia Battery of Chinese (Aphasia Battery of Chinese,ABC) and the Chinese agraphia battery (Chinese agraphia battery,CAB ) in addition to a series of other neuropsychological tests.Results( 1 ) On the Wechsler Adult intelligence scale,the patient performed poorly on information and vocabulary with scores of 6/29 and 8/80,respectively.He spoke out only 11 names totally on the category fluency test within 1 minute,while 25 names or more than were normal.Semantic features test showed he made 37 right answers of 60 questions,with scores of 8/20 on category,7/20 on function and 8/20 on nature features.(2)The writing disorder exhibited Chinese aphasia agraphia with obvious difficulty in forming characters,wrong characters of the same pronunciation or the same form or unrelated errors,and grammatical impairments.Its damage from serious to light occurred in picture writing( 6/40),writing sentences to convey meaning(1/10),dictation(11/40) and automatic writing(35/40).The transcription was relatively preserved (40/40 ). (3)He scored 20 and 19 points on MMSE and MoCA.Executive function was damaged significantly,while recent memory was preserved relatively.ConclusionThe patient with SD shows an impoverished store of general knowledge and poor comprehension of single-word.The nature of SD's dysgraphia presents Chinese aphasia agraphia,undoubtedly due to progressive deterioration in semantic memory.More importantly,its error types and distribution show apparent discrepancy from that of alphabetic script.Presumably because Chinese writing system is logographic in nature and the pathway of comprehension concerning syllable-orthography-morphemes mapping,while alphabetic writing system follows a principle of mapping graphemes on-to phonemes and letters themselves dont stand for any meaning.

Objective To explore the effects of nutritional intervention on body composition,blood biochemical parameters and blood pressure of overweight adults with metabolic syndrome.Methods Forty overweight adults with metabolic syndrome (body mass index (BMI) ＞ 28.0 kg/m2,waist circunference ≥85 cm(for male)or ≥80 cm(for female))participated in this investigation.Changes of serum lipid profiles,blood glucose,blood pressure and other indicators were compaired before and after 2-months'intervention.SPSS 18.0 Software was used for data analysis.Results After two rnonths' nutritional intervention,body weight,body fat,BMI,visceral fat area and waist hip ratio were significantly improved(t =17.02,11.07,5.11,10.35,9.58 ; P ＜ 0.05).The glutamic-pyruvic transaminase,glutamic-oxalacetic transaminease,cholesterol,triacylglycerol,fasting blood-glucose,systolic blood pressure and diastolic blood pressure were also significantly improved after nutrition intervention(t =2.87,2.91,3.33,2.24,2.56,5.74,6.99 ;P ＜ 0.05).Conclusion Nutrition intervention may contribute to improved levels of blood pressure,blood glucose and serum lipid profiles of obesity individuals through body weight and body fat control and lead to reduced insulin resistance caused by obesity.

Background & Objective: Early life stresses, such as social isolation, have lasting effects on the development of emotion and behavior, in which vasopressin plays important roles. This study aimed to assess the possible association of central release of vasopressin with social isolation. Methods: The social isolation model was performed in male mice who endured 6-week social isolation after weaning. Vasopressin expression in the paraventricular nucleus of hypothalamus (PVN) was measured with immunohistochemistry. Released vasopressin from PVN was measured with radioimmunoassay. Results: Vasopressin immunoreactive cells number decreased in the PVN, medial parvocellular division in social isolation-reared mice, compared to the group-reared counterparts. Social isolation decreased short social exposure-induced vasopressin release from PVN. Isolation-reared mice exhibited anxiogenic profile and difficulty in social recognition. Conclusions: This study provides new evidence for the important role of vasopressin in the development of emotional and social behaviors.

Berberine is the main active ingredients in Coptis.The content determination of berberine can provide the basis for its quality evaluation.Relevant provessinal literatures about determination methods of berberine were summarized,and the main methods included TLC,UV, HPLC,HPEC,fluorescence,and so on.HPLC was the most widely used method because of its high separation efficiency,specificity and sensitivity.

Objective To observe the changes in gut mucosal barrier and gut-origin bacteria-endotoxin translocation in acute necrotizing pancreatitis (ANP) rats. Methods Wistar rats were divided randomly into normal group (n=6), sham operation group (n=30) and ANP group (n=39). ANP was introduced by infusion of artificial bile into biliopancreatic duct. Morphology of pancreas and intestine were observed and tight junction on ileum epithelia were assessed by cryofracture replicas electroscopy. Plasma levels of D-lactic acid and endotoxin were examined at various time points. The rates of bacterial translocation to abdominal organs were also calculated. Results Mucosal and tight junction damages of the gut were found during early stage of ANP. Simultaneously, plasma D-lactate levels increased and endotoxemia occurred. The rate of bacterial translocation to organs was 59.5% 72h after ANP occurred. Conclusions Gut barrier function can be injured in the early stage of ANP, and resulting in gut origin bacteria-endotoxin translocation, which may be the originator of systemic inflammatory reaction and secondary infection of the pancreas.
