Herbal property theory of traditional Chinese medicines is the theoretical guidance on authentication of medicinal plants, herborization, preparation of herbal medicines for decoction and clinical application, with important theoretical value and prac- tical significance. Our research team proposed the "three-element" theory for herbal properties for the first time, conducted a study by using combined methods of philology, chemistry, pharmacology and mathematics, and then drew the research conclusion that herbal properties are defined as the chemical compositions-based comprehensive expression with complex and multi-level (positive/negative) biological effects in specific organism state. In this paper, researchers made a systematic mathematical analysis in four aspects--the correlation between herbal properties and chemical component factors, the correlation between herbal properties and organism state fac- tor, the correlation between herbal properties and biological effect factor and the integration study of the three elements, proposed future outlook, and provided reference to mathematical studies and mathematical analysis of herbal properties.

Objective To evaluate the effect of SYNTAX score in the emergency revascularization strategy selection in ST‐segment elevation myocardial infarction patients with multi‐vessel disease(MVD) and to analyze the patient′s prognosis and influen‐cing factors .Methods A total of 144 patients with STEMI complicating MVD verified by coronary arterial angiography in the Xin‐qiao Hospital of Third Military Medical University from August 2010 to March 2012 were collected and divided into the once com‐plete revascularization group (CR group) ,staged complete revascularization group (SR group) and incomplete revascularization group (IR group) according to different emergency PCI strategies .The basic clinical conditions and coronary arterial SYNTAX score were recorded .The occurrence rate of major adverse cardiovascular events (MACCE) during 12 months follow up period was performed the statistics .The results of coronary arterial angiography were collected .The effect of different strategy on prognosis and the risk factors affecting prognosis were analyzed .Results There was no statistically significant difference in the all‐cause mor‐tality between the IR group with the CR and SR groups (P>0 .05) ,while the cerebrovascular event ,repeat revascularization during hospitalization ,AMI and total MACCE occurrence rate had statistical difference between the IR group with the CR and SR groups (P<0 .05) .The main influence factors of MACCE were complicating diabetes mellitus ,type C lesions ,SYNTAX score ,D‐B time , myocardial infarction area ,TIMI score in PCI ,no reflow existence and cardiac shock (P<0 .05) .According to the SYNTAX score , the occurrence rate of MACCE in mild or severe lesions had no statistical difference among 3 groups(P> 0 .05) ,while which in moderate lesion had statistical difference among 3 groups(P<0 .05) ,the CR group had the highest occurrence rate of MACCE . Conclusion For the patients with STEMI complicating MVD ,the SYNTAX score can be used as the evidence for selecting reperfu‐sion strategies and applied in emergency PCI .

Objective To study the influence factors on the enflurane uptake in child with congenital heart disease(CHD).Methods Sixty children aging less than 5 years with CHD were randomly divided into four groups: in group A 15 children with atrial septal defect(ASD)or ventricular septal defect (VSD) inhaled enflurane before and after CPB;in groups B 15 children with ASD or VSD did only after CPB,in group C 15 children with tetralogy of fallot (F4) did before and after CPB;in group D 15 children with F4 did only after CPB.The concentration of enflurane (F I) was kept at 0.5%.Following inhalation of enflurane,the end tidal alveolar concentration (F E) was measured in 30 min and the time of uptake equilibrium (Tue,F E/F I=1) was recordcd.Results In group C,Tue before CPB was shorter than that before CPB and after CPB in group A,that in group B and group D (P

[Objective]To investigate the effects of doxycycline on rabbit immobilized osteoarthritis and their mechanism.[Method]Twenty-four rabbits were randomly divided into normal,model,control and treatment groups,with 6 rabbits in each group.All of the animals were immobilized the lower left limbs with plaster bandage for 4 weeks except normal group.Doxycycline was orally given to treatment group.Cartilage degeneration of the medial condyle of femur was observed at 4 weeks and the levels of collagen-Ⅱ,uPA and MMP-13 were tested.[Result]Cartilage degeneration in treatment group was significantly slighter than those in model and control groups.Data of collagen-Ⅱ,uPA and MMP-13 between model and control groups had no significant difference,but a noticeable statistical difference among other groups.The uPA activity was positively correlated with MMP-13.[Conclusion]Doxycycline inhibits the degeneration process of cartilage and improves the structure.The effects may be related to the inhibition of uPA and MMP-13.

Objective To investigate the clinical characteristics of general paresis of insane(GPI) and diagnostic value of laboratory and neuroimaging examinations.Methods The clinical data of 2 patients with GPI were analyzed retrospectively and the pertinent literatures were reviewed.Results The main clinical characteristics consisted of insidious onset,progressive dementia,mental disorder and epileptic seizure.These 2 patients were originally misdiagnosed.Both rapid plasma reagin test and treponema gelatin agglutination test in serum and cerebrospinal fluid were positive.Cranial MRI showed diffuse cerebral atrophy.Conclusions The clinical characteristics of GPI are varied and misdiagnosis rate is high at early stage of this disease.The diagnosis of GPI mainly depends on clinical characteristics,serum and cerebrospinal fluid examinations.

0.990).The intra-assay and inter-assay variation of the method was 3.10 % and 4.93 %,respectively.The all-trans ratinoic acid(ATRA) up-regulated t-PA mRNA expression in a dose-dependent manner(1.25~20.00 ?mol?L~(-1),P

Objective To characterize the properties of human immunodeficiency virus-1-(HIV-1)specific cytotoxic T lymphocyte(CTL)responses,and to analyze the factors which may affect CTL responses before and after treatment with highly active antiretroviral therapy(HAART)in children with chronic HIV-1 infection.Methods A total of 24 HIV-1-infected children were studied.Circulating CD4 T cell counts and HIV-1 RNA levels were routinely measured.Peripheral HIV-1-specific CTL frequency and the specific interferon-?-producing lymphocytes were determined by tetramer staining and enzyme-linked immunospot(ELISPOT)assay,respectively.Results It was found that HIV-1-specific CTL responses could be detected in vitro in more than 80% of Chinese children with HIV-1 infection.Circulating CTL frequency and IFN-?-producing lymphocyte counts were significantly reduced in HAART suppressed HIV-1 infected children in comparison with HAART failure children and HAART na?ve children.The duration of virus suppression after HAART was found to be inversely correlated with CTL frequency.Conclusion HIV-1-specific CTL response to virus was warranted by antigenic stimulation.The present work may elucidate the immune mechanisms influencing the outcome of HIV-1 carriers with treatment of HAART.

OBJECTIVE To examine directly the fungal pathogens from nasal sinus under microscope and identify them.METHODS The nasal sinus secretion from 36 cases with fungal infection was directly examined microscopically,cultured,and identified for fungi.RESULTS Direct microscopic examination was positive in 34 cases and from them 24 were with positive cultures: 19 had infection of Aspergillus,3 of Scedosporium spiosperimum,1 of Pseudallescheria boydii,and 1 of Alternaria.CONCLUSIONS Aspergillus are the main pathogens in nasal sinus fungal infection.

The aim of this study was to construct antisense of ZNRD1 encoding gene, and to transfect it into SGC7901/VCR cells, to seek measures to overcome multidrug resistance of gastric cancer cells. ZNRD1 cDNA amplified by PCR was confirmed by DNA sequencing, and then inserted into the multiple cloning site of the expressing vector pcDNA3 1 + with molecular cloning technique. The recombinant vector was identified by endonuclease digestion. Antisense recombinant vector was transfected into SGC7901/VCR cells using lipofectamine. Flow cytometric analysis was used to detect adriamycin (ADM) accumulation in SGC7901/VCR cells. The results showed that a fragment was obtained by PCR, and its sequence was consistent with ZNRD1 cDNA reported in the literature. After antisense recombinant vector having been transfected into SGC7901/VCR cell, ADM concentration in such cells was increased. The above results indicated that the antisense vector ZNRD1 could enhance the intracellular accumulation of ADM in SGC7901/VCR cells, which might be of potential treatment value.
