Objective To figure out changes of serum excitatory amino acids (EAAs) levels in patients with amnestic mild cognitive impairment (aMCI) and Alzheimer's disease (AD).Methods The levels of serum EAAs was assessed in 34 cognitively normal control subjects,30 patients with aMCI,and 32 patients with AD using high performance liquid chromatography (HPLC).Results ①Higher serum concentrations of glutamate((39.6?22.1) ?mol/L),alanine((282.5?71.3) ?mol/L) were found in the aMCI patients (P=0.044,P=0.007),and higher serum concentrations of glutamate ((42.2?21.8) ?mol/L),glycine ((464.2?142.6) ?moL/L) were found in the AD patients than in the control subjects (P=0.010,P=0.010).②No statistically significant difference of EAAs level between the aMCI and AD groups was found.③A close and positive correlation between the serum concentrations of glutamate, aspartate and the mini-mental status examination scores were found in AD patients:the 2 amino acid levels were higher in patients with mild dementia((42.1?21.3),(55.0?29.0) ?mol/L) than those with moderate or severe dementia ((25.4?9.2) ?mol/L,P=0.023;(34.6?11.1) ?mol/L,P=0.036). Conclusion EAAs,correlating with the severity of the condition,play a significant role in AD,while aMCI patients also have disturbance of metabolism of EAAs,indicating that it has similar pathogenesis to AD.

group Nor(P0.05).Conclusions The changes of ambulatory pulse pressure can reflect the degree of EH.The obvious increase of PP and decrease of DBP maybe are the exclusive features of ABPM in EH patients with target organs damage.

Objective To study the role of glucocorticoid (GC) in treating patients with cyto- megalovirus (CMV) pneumonia following renal transplantation.Methods There were 75 cases CMV pneumonia following renal transplantation during one month (3 cases),2-6 months (64 cases) and more than 6 months (8 cases).All patients were subjected to the comprehensive treatments including anti-virus therapy.In 47 cases,GC was given (GC group),and in the rest 28 cases,GC was not administered (non-GC group).Results In GC group,40 cases (85.1%) were cured and there were 7 deaths (14.9%).In non-GC group,17 cases (60.7%) were cured and there were 11 deaths (39.3%).There was significant difference between two groups (P

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

ObjectiveTo assess the satisfaction of general practical students' perception with the two modes of histologic laboratory instruction,and obtain the advantages and disadvantages of each mode.MethodsWeb-based database was established and in the questionnaires were delivered to the general practical students ( n=193 ).Results75％ of students agreed that the case study component of the webbased laboratory instruction was arranged in order.82％ of students identified with the detailed word explanation attached to every image presented.ConclusionStudents support the progression of web-based histologic laboratory instruction,but it is difficult to replace traditional microscope with web-based database in histologic laboratory instruction.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

In this paper, the RP-HPLC specific chromatography was adopted, with DIKMA-C18 (4.6 mm x 250 mm, 5 µm) as the chromatographic column, with a gradient elution compose of acetonitrile and 0.1% phosphoric acid at flow rate of 0.8 mL · min(-1), the detection wavelength was 220 nm. The difference of the HPLC specific chromatograms between the Lu Dangshen and other different base sources and different producing area of Codonopsis Radix was compared, involved in the similarities and differences of the number and the relative peak area of characteristic peaks in the HPLC specific chromatograms. The HPLC specific chromatograms of Lu Dangshen was established and the relative retention times of seven peaks was determined, and the peaks of codonopyrrolidium B, syringin, lobetyolin, tangshenoside I and atractylenoide III were identified; The HPLC specific chromatograms of Lu Dangshen provided a method for scientific evaluation and effective control the quality of Lu Dangshen from Shanxi famous-region.
