Objective To investigate the expressions of the CD13 in gastric cancer and the relationships between it and the patients' prognosis.Methods The expressions of CD13 were detected by immunohistochemical (SP method) in 104 cases of gastric cancer and 16 cases of normal gastric mucosa.Results The expressions of CD13 in 104 cases of gastric carcinoma and 16 cases of normal gastric mucosa show positive rate were 74％ (77/104) and 0％,respectively.The expressions of CD13 in gastric cancer were higher than in normal gastric mucosa and the difference was statistically significant (P ＜ 0.01).The expressions of CD13 in gastric cancer were not relative to patients' age,gender,and lymph node metastasis (P ＞ 0.05),but to be correlative with tumor sizes,clinical stage,degree of differentiation,and patients' 5-year survival rate (P ＜ 0.05).Conclusions The abnormal expression of CD13 in the gastric cancer may be correlative with the occurrence and development of gastric cancer,which can be an important indicator to evaluate the degree of malignance,guide treatment and assess uncertain prognosis of gastric cancer.

In traditional Chinese medicine,medical practice is combined with qi,which forms special qi-theory.Body fluid which includes blood and Jin-ye is the fluid structure of human being.Nutrient qi and defensive qi depend on these two kinds of body fluid.Defensive qi not only maintains physiological functions of Jin-ye,but also participates pathomechanism such as Jin-ye consumption,retention,etc.The identity of defensive qi and Jin-ye plays an important role in theory and clinic.

OBJECTIVE: To construct the data envelopment analysis (DEA) inference model for word-computing. METHODS: Firstly, a syndrome assembly was established based on the Chinese medical patterns contained in Shanghanlun, then the subjective evaluation was set by the linguistic description for the corresponding patterns. Secondly, with the data of decoctions, the evaluation was modified according to the requirement of DEA to construct the inference model. Finally, the word-computing was completed by the inference function of this model. RESULTS: DEA model could describe the diagnostic thinking process of Shanghanlun theory. CONCLUSION: DEA model can upload the information embodied among the words of the corresponding classical doses and symptoms, and it provides a kind of method for modernization of traditional Chinese medicine.

Objective To realize job satisfaction of doctors from the secondary hospital and its influencing factors and put forward countermeasures for doctor job satisfaction.Methods 2066 doctors from the secondary hospital were investigated by self-made scale,and analyzed by analysis of variance,non-conditional logistic regression analysis and other methods.Results The average score of total job satisfaction of doctors was (3.44±0.95),in which about 57.6% of doctors expressed satisfaction with the current work.The scale of job itself satisfaction had the hisheet score,that was (3.91±0.79),while the scale of job retum satisfaction had the lowest score,that was (2.85±1.16).Leadership behavior played the most decisive role in doctors job satisfaction(sβ=0.7,P<0.01).Condusion The total job satisfaction of secondary hospital doctors is just above the average and doctors are most dissatisfied with the work concentrated in the areas of return and the practice environment.

OBJECTIVETo observe and evaluate the clinical performance of zirconia crowns made by CEREC inLab computer aided design/computer aided manufacturing(CAD/CAM) for posterior teeth.

METHODSA total of 242 patients were implanted with zirconia crowns fabricated by CEREC inLab CAD/CAM. The crowns were evaluated by Modified US Public Health Service criteria at baseline, 6, 12, 24, and 36 months. The chi-square test was used to analyze the survival rate.

RESULTSAll but five crowns were evaluated by an independent evaluator at baseline, 6, 12, 24, and 36 months. The survival rate declined with time. The A score percentage was above 85% at 36 months.

CONCLUSIONThe single zirconia crowns fabricated by CEREC inLab CAD/CAM demonstrate satisfactory clinical performance during a short period.

Objective To summarize the clinical,radiographic and genetic features of a family with metatropic dysplasia,in order to improve the level of understanding and diagnosis of this disease.Methods The proband,a one-year old boy,was diagnosed as metatropic dysplasia.His mother was 26 years old with mildly phenotype.Their clinical features and bone X-ray findings were analyzed.The DNA samples of the proband and his parents were collected.The coding exons and flanking introns regions of transient receptor potential vanilloid 4 (TRPV4) gene were amplified by polymerase chain reaction (PCR) and analyzed by DNA automatic detector.The pathology,diagnosis,treatment and prognosis were expounded.Results The symptoms of the boy were characterized by short extremities,a short trunk with progressive kyphoscoliosis,and craniofacial abnormalities that include a prominent forehead,midface hypoplasia,and a squared-off jaw.His motor development was slightly delayed.Mental development was normal.Bone X ray of the boy showed platyspondyly and severe metaphyseal enlargement with shortening of long bones and irregularities and delayed ossification of epiphysis.The patient and his mother were heterozygous for the nucleotide substitutions c.2396 ＞ T (p.P799L) in TRPV4 gene.Conclusions The patient and his mother with metatropic dysplasia were diagnosed with TRPV4 gene analysis.The patient showed typical clinical features.His mother was mild.Metatropic dysplasia had significantly clinical heterogeneity.Gene analysis is helpful for the diagnosis.
