To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities, moodiness and weak constitution; the pathogenesis of CAG was spleen deficiency with qi stagnation, heat depression and blood stasis in the stomach meridian. The above six syndrome types and 12 herbs were determined, including Pseudostellariae Radix, Poria, Atractylodismacrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Fritillariae Thunbergii Bulbus, Sepiae Endoconcha, Arecae Pericarpium, Aurantii Fructus, Perillae Caulis, Herba Hedyotis Diffusae, Scutellariae Barbatae Herba, Curcumae Rhizoma. This study summarized Professor LIU Feng-bin's clinical experience and theoretical thoughts of chronic atrophic gastritis based on clinical practice data and expert interview, with a rigorous design and good scientificity and practicability.

OBJECTIVETo summarize the experience of surgical treatment of the hilar cholangiocarcinoma and explore the factors influencing the operative effect.

METHODSFifty-three cases of hilar cholangiocarcinoma performed operation from January 1998 to January 2008 were divided into two groups: Group I included cases treated from January 1998 to December 2002 (totally 22 cases); Group II included cases treated from January 2003 to January 2008 (totally 31 cases). Comparative study was carried out between these two groups.

RESULTSSurgical resection [radical resection (R(0)) + palliative resection (R(1))] rate in group I was lower than that in group II (40.9% vs. 71.0%, P = 0.029). Hepatic lobectomy rate in group I was lower than that in group II (30.0% vs. 64.5%, P = 0.016). The resection rate was positively correlated with the hepatic lobectomy rate (r = 0.985, P < 0.01). The median survival time of the patients underwent R(0) resection was longer than that in the patients underwent R(1) resection and palliative bile duct drainage [(27.0 +/- 4.5) months vs. (10.0 +/- 0.7) months vs. (4.0 +/- 0.5) months, respectively, P < 0.01].

CONCLUSIONSEarly diagnosis and radical resection are important to improve the prognosis for patients with hilar cholangiocarcinoma. But for the patients could only receive palliative resection or with positive celiac trunk lymph nodes, combined liver lobe resection could not improve the survival.

Nowadays, the simple combination of Western medicine (WM) and complementary and alternative medicine (CAM) cannot resolve all the health problems and various requirements. This article proposed the general integral medicine (GIM) theoretical model, which declares the disease causes analysis, clinical intervention and outcomes assessment should be recognized, managed and evaluated both from physiological, psychological, and spiritual status, and all the four dimensions: orthodox medicine (WM, Chinese medicine, etc.), individual inherent characteristics (emotion, attitude, psychology, etc.), cultural influences (doctors, caregivers, groups care, etc.), and natural environment and social systems (economic status, social security system, environmental pollution, etc). As for health outcomes assessment, a more comprehensive system including biological, doctors, patients, health intimate, social and environmental evaluations were required. The GIM model has individualized, dynamic, standardized, objective, systematic inherent characteristics, and opening and compatible external characteristics. It aims to provide the new theoretical guidance and strategic development direction for complex health interventions, and solve various medical related psychological and social problems.

OBJECTIVETo investigate the molecular subtypes of 73 strains of Yersinia enterocolitica biotype 1A isolated in Shandong province by PFGE, and thereby to analyze the relationship between PFGE typing and biological characteristics.

METHODSSeventy-three strains of Yersinia enterocolitica biotype 1A were isolated from animal feces and meat products in Gaomi city and Wulian county in Shandong province from 2008 to 2009. Motility test, serum agglutination and virulent genes detection by PCR were used to learn the biological characteristics of the isolated strains. The molecular subtypes were determined by PFGE, whose relationships with motility, serotypes and virulent genotypes were also analyzed.

RESULTSOut of the 73 strains of Yersinia enterocolitica, 5 showed medium-active motility while the other 68 showed well-active motility. The dominated serotypes were O:5(17/73) and O:8(14/73), followed by O:9(5/73) and O:7, 8(1/73), and there was no O:3 serotype found. Meanwhile, 36 strains couldn't be serotyped. All the strains were negative with the gene ail, ystA, yadA and virF, yet the positive rate of ystB gene was 72.6% (53/73). The 73 strains of Yersinia enterocolitica isolated could be subtyped into 54 PFGE patterns (K6GN11SD0001-K6GN11SD0054), most of which only had 1 or 2 isolated strains, and no pattern was dominant. The strains in the same or similar cluster were from different hosts; each serotype and toxic genotype scattered in the clustering trees, without specific correlation with PFGE subtypes. 4 out of 5 strains, which showed medium-active motility, belonged to one branch, with the similarity coefficient at 80.9% - 100.0%; while all the toxic genotype belonged to type B.

CONCLUSIONBiotype 1A Yersinia enterocolitica has many clones, whose PFGE types had relations with motility, but no relations with virulent genotype and host.

Objective To understand the main serotypes, antibiotic resistance profiles and molecular typing characteristics of Listeria monocytogenes（LM) isolated from foods in Shandong Province from 2013 to 2016. Methods The antibiotic sensitivity of LM was tested by broth microdilution method. The serotypes were determined by slide agglutination and PCR, and the molecular typing was carried out by pulsed field gel electrophoresis (PFGE) and multilocus sequence typing(MLST) . Results Most of 191 LM strains were sensitive to the eight antibiotics tested. Tetracycline resistance was most prevalent (15/191, 7.85%). There was no significant difference in the 8 antibiotic resistance monitored for 4 years (P=1.000). The serotype 1/2a, 1/2b and 1/2c accounted for 38.82% (66/170), 18.82% (32/170), and 42.36% (72/170), respectively. The patterns of SDSRZXDZ016, S2014L031 and SDSRZX030, totally accounted for 33.78%, were the dominant types. The main ST types were ST9, ST8 and ST121, which accounted for 81.18% (69/85). The clinical common types, ST3, ST7 and ST87 accounted for 8.23% (7/85), mainwhile new ST type was not found. Conclusion The LM strains isolated in Shandong Province from 2013 to 2016 were sensitive to most antibiotics, but some strains were resistant to tetracycline and erythromycin. The dominant serotypes were 1/2c and 1/2a. Serotype 4b, prone to outbreaks of listeriosis, was not found. The main PFGE types were SDSRZXDZ016, S2014L031 and SDSRZX030, which were continuously found from 2013 to 2016. The main ST types were ST8, ST9 and ST121. The clinical types, ST3, ST7 and ST87 were isolated from food and should be paid seriously attention to.

Objective To research the distribution and molecular epidemiology of insertion sequence IS1301 in Neisseria (N.) meningitidis strains in China, so as to provide scientific and available evidence for a new method of genotyping in N.meningitidis strains with IS1301. Methods Examined the IS1301 by PCR in 219 N.meningitidis strains from 16 provinces and 3 cities during 2007 and 2008 in China, productions of amplification were sent for sequencing. The positive N.meningitidis strains were analyzed by pulse field gel electrophoresis (PFGE) and nucleic acid blotting hybridization(Southern blot) by electrophoresis. Results The positive rates with IS1301 were 15.53%, 11.11%, 20.75%, 6.17% and 28.57% for four serotypes (A, B, C, N) respectively. The sequence comparability between the amplification productions and No.Z49092.1 N.meningitidis which registered in GenBank was 94%-100%. There were two types of clusters devided by cladogram analysis. There appeared large IS1301 sequence difference between the serotype C and others. The number of IS1301 replica ranged from 6-17 per strain at least. The number of IS1301 replica changed in the same type of PFGE N.meningitidis respectively. Conclusion Typing by IS1301 combined with PFGE could comprehend the homology and genetic polymorphism of N.meningitidis epidemic strains at the molecular level.

OBJECTIVETo evaluate the application of health assessment instruments in Chinese medicine.

METHODSAccording to a pre-defined search strategy, a comprehensive literature search for all articles published in China National Knowledge Infrastructure databases was conducted. The resulting articles that met the defined inclusion and exclusion criteria were used for analysis.

RESULTSA total of 97 instruments for health outcome assessment in Chinese medicine have been used in fundamental and theoretical research, and 14 of these were also used in 29 clinical trials that were randomized controlled trials, or descriptive or cross-sectional studies. In 2 152 Chinese medicine-based studies that used instruments in their methodology, more than 150 questionnaires were identified. Among the identified questionnaires, 51 were used in more than 10 articles (0.5%). Most of these instruments were developed in Western countries and few studies (4%) used the instrument as the primary evidence for their conclusions.

CONCLUSIONUsage of instruments for health outcome assessment in Chinese medicine is increasing rapidly; however, current limitations include selection rationale, result interpretation and standardization, which must be addressed accordingly.

OBJECTIVETo study the molecular mechanism of TAp63gamma-induced cell apoptosis.

METHODSTranscription and protein expression of apoptosis inducing factor and p63 were investigated by immunohistochemistry and RT-PCR in human esophageal squamous carcinoma cell line EC9706 respectively. Twenty-four hours after transfection with pcDNA3.1-TAp63gamma, the apoptosis and translocation of apoptosis inducing factor in EC9706 cells were studied by flow cytometry, laser confocal microscopy and mitochondrial/cytosol/nuclear extraction analysis respectively. Down-regulation of apoptosis inducing factor protein was achieved by RNAi and pretreatment with caspase inhibitor zVAD.fmk of EC9706 cells.

RESULTSPresence of protein expressions of apoptosis inducing factor and absence of TAp63gamma was observed in the cytoplasm of untransfected cells. RT-PCR verified the subtype of p63 in EC9706 cells was DeltaNp63. After 24 hours of transfection, both nuclear and cytoplasmic expression of apoptosis inducing factor protein were observed in cells transfected with TAp63gamma and p53 expression vectors, but not in cells transfected with control vector. Cell apoptosis rates were 1.37%, 13.64%, 4.52%, 4.03% and 1.91% in the pcDNA3.1 transfection group, pcDNA3.1-TAp63gamma transfection group, apoptosis inducing factor siRNA and pcDNA3.1-TAp63gamma transfection group, zVAD.fmk treatment group, and the group receiving apoptosis inducing factor siRNA, plus zVAD.fmk treatment and pcDNA3.1-TAp63gamma transfection, respectively.

CONCLUSIONSApoptosis inducing factor of EC9706 cells is released from mitochondria into both the cytoplasm and nucleus during TAp63gamma induced apoptosis. Down-regulation of apoptosis inducing factor inhibits TAp63gamma-induced apoptosis. Overall, TAp63gamma-induced apoptosis is dependent on the expression of apoptosis inducing factor and caspase.
