To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

The combination of medicinal properties refers to expression forms of elements with active properties combined according to a specific sequence. The mode of medicinal property combination refers to the compatible relationship multiple medicinal property combinations. In this paper, based on the mode, safflower, Taohong Siwu decoction, Xuefu Zhuyu decoction and Buyang Huanwu decoction were taken for example to study the characteristics of the compatibility among single herb, herbal pairs and prescriptions. The authors discovered the similarities and differences among them, interpreted the self-similarity in medicinal property combinations of traditional Chinese medicines, and analyzed the compatible relationship among multiple medicinal property combinations, so as to bring forth new ideas in discovering the correlation between the compatibility study mode of traditional Chinese medicines based medicinal property combinations and the efficient compatibility of medicinal property combination.

Objective To explore the associations between microsatellites in gonadal receptor genes and dysfunctional attitudes in adolescent with major depressive disorder(MDD).Methods Polymerase chain reaction(PCR),capillary electrophoresis and genetic scanning were performed in testing the length of microsatellites in first-onset adolescent depressive patients.Dysfunctional attitudes scale(DAS) was used in rating the dysfunctional cognition of adolescent depressive sample.These results were tested by correlative analysis and comparison analysis.Results 1.There existed significantly negative correlation between microsatellite′s length in estrogen receptor ?(ER?) gene and total score of DAS in female adolescent patients with first-onset depressive disorder.2.DAS′ total score of shorter alleles′ group was significantly higher than that of longer alleles′ group on female′ estrogen receptor ?(ER?) Gene.Conclusion The microsatellite′s length of ER? and ER? gene may have associations with dysfunctional attitudes of female adolescent with MDD.

A strain with relative higher phytase-producing ability, Aspergillus fumigatus WY-2 was screened from soil. The optimal pH and temperature for activity of the phytase from A.fumigatus WY-2 were 5.5 and 55 ℃, respectively. The gene encoding the phytase was amplified from genomic DNA of the strain by PCR, and a 1.5 kb DNA fragment was obtained and then was cloned into vector pMD18-T. The sequencing analysis revealed that the DNA fragment contained a whole open reading frame (ORF) of phytase gene. The phytase gene was 1459 bp in length included with a 61 bp intron and encoded 465 amino acids. A signal peptide encoding 26 amino acids was found at 5′end of the gene. There were 7 potential glycosylation sites in the phytase. The present phytase showed 91% identity in nucleotide sequence and 91% identity in deduced amino acids sequence to the previously reported A.fumigatus ATCC34625 phytase.

Multi-component traditional Chinese medicines are an innovative research mode for traditional Chinese medicines. Currently, there are many design methods for developing multi-component traditional Chinese medicines, but their common feature is the lack of effective connection of the traditional Chinese medicine theory. In this paper, the authors discussed the multi-component traditional Chinese medicine design methods based on medicinal property combination modes, provided the combination methods with the characteristics of traditional Chinese medicine for the prescription combinations, and proved its feasibly with hypertension cases.

OBJECTIVE: To study the disability identification for cases with clinical diagnosis of diffuse axonal injury (DAI) due to traffic accidents, and to explore the possible effects of DAI on identification results. METHODS: Five hundred and fifty-six cases of cerebral injury due to traffic accidents were collected, including 467 cases diagnosed with cerebral contusion or laceration and 89 cases diagnosed with DAI. The identification results of different groups with diagnosis of DAI diagnosis, diagnosis of DAI with cerebral contusion (laceration), and diagnosis of cerebral contusion or laceration without DAI were compared and statistically analyzed, based on the results of CT and MRI re-review. RESULTS: The disability identification levels in DAI group (20 cases), DAI group (69 cases) with cerebral contusion (laceration) and DAI group (467 cases) not complicated by cerebral contusion (laceration) were 7.72 +/- 1.09, 7.78 +/- 1.11, and 8.86 +/- 0.66, respectively. The disability levels of the two groups diagnosed with DAI were higher than those of the group without DAI diagnosis (P < 0.05). CONCLUSION Patients with DAI diagnosis might have more severe cerebral injury. In the identification process, one should pay attention to the possible missed diagnosis and misdiagnosis, and meanwhile avoid relying on those evidences provided only by CT and MRI.

OBJECTIVETo evaluate the clinical significance of the application of fluorescence in situ hybridization (FISH) in detecting chronic myeloid leukemia (CML).

METHODSChromosome preparation was made by using 24-hour culture. FISH technique using dual color dual fusion (DC-DF) BCR/ABL probe was performed in all 158 cases and R-banding was also employed for karyotyping in some patients.

RESULTSAmong the 158 cases, 98 cases were Ph positive, of which 69 cases (70.4%) were typical FISH pattern (1R1G2F), the other 29 cases (29.6%) showed 12 different types of atypical FISH pattern. The most frequent atypical patterns found were 1R1G1F in 7 cases (7.1%), 2R1G1F in 5 cases (5.1%), 1R1G2F and 1R1G3F in 4 cases (4.1%), 2R2G1F in 3 cases (3.1%). Karyotype analysis on 18 CML cases with atypical FISH patterns demonstrated that the atypical FISH patterns were due to variant translocation in 3 cases; the additional third signal was because of a supernumerary Ph chromosome. The karyotyping results did not conform to FISH results in four cases suggesting the conceivable mistakes in karyotyping. The 1R1G1F signal pattern seen in 3 cases with classical t(9;22) resulted from the deletion of derivative chromosome 9. The 1R1G2F signal pattern detected in 40% to 64% of interphase cells of 3 cases without Ph chromosome by conventional cytogenetic analysis suggested a submicroscopic translocation. Three cases treated with Glivec or bone marrow transplantation showed normal karyotypes with a small amount of BCR/ABL positive cells by FISH detection.

CONCLUSIONFISH technique is of great value for the diagnosis of CML and confirmation of variant translocation, occult Ph translocation, derivative chromosome 9 deletion, therapeutic effect of interferon and Glivec as well as detection of minimal residual disease after bone marrow transplantation.

OBJECTIVETo study the effects of citalopram on the expression of proliferating cell nuclear antigen (PCNA) and proto-oncogene protein (C-fos) and cell apoptosis in frontal cortical neurons of rat after stress.

METHODSTwenty four healthy male SD rats were randomly divided into three groups (n = 8): control group, stress group (treated with saline, ig) , experimental group (treated with Citalopram 4 mg/kg x d for 28 days, ig). Rats were forced to swim to establish chronic stress model. The protein expression levels of PCNA and C-fos were tested by immunohistochemistry assay. TUNEL assay was used to test cell apoptosis. Nikon image analysis software was used to determine the number of positive cells in each index.

RESULTSCompared with the control group, the stress group showed a smaller amount of PCNA-positive cells, a larger number of C-fos positive cells, and the volume of positive cells was significantly reduced. Compared with the stress group, the PCNA positive cells were increased significantly, the C-fos positive cells and TUNEL positive cells were decreased significantly, nuclear condensation phenomenon in frontal cortical neurons and the staining was significantly lighter in experimental group (P < 0.05).

CONCLUSIONCitalopram significantly antagonize PCNA, C-fos protein expression and cell apoptosis of rat prefrontal cortical neurons caused by chronic stress, which might be the one of mechanisms of citalopram for prevention and treatment of psychosis caused by chronic stress.

OBJECTIVETo review the research progress on Type IV secretion system (T4SS) in Helicobacter pylori.

DATA SOURCESThe data used in this review were identified by searching of PUBMED (1995 - 2007) online resources using the key terms 'Type IV secretion system' and 'Helicobacter pylori'.

STUDY SELECTIONMainly original articles and critical reviews written by major pioneer investigators of this field were selected.

RESULTSThe research progress on T4SS in Helicobacter pylori was summarized. The structure and function was discussed.

CONCLUSIONST4SS is not only involved in toxin secretion and injection of virulence factors into eukaryotic host target cells, but also involved in horizontal DNA transfer to other bacteria and eukaryotic cells, through DNA uptake from or release into the extracellular milieu. It provides a new insight into the pathogenicity of Helicobacter pylori and a novel target for antimicrobials development. However, many challenges remain for us in understanding the biological role of T4SS in Helicobacter pylori.
