【Objective】 To study the location effect of the Mc Ab G9 to human esophageal carcinoma in tumor bearing nude mice. 【Methods】 125　I-G9 was prepared by Chloramine-T method. The distribution of 125 　 I-G9 was detected at different time (24, 48, and 72 h) after peritoneal injecti on. The percentage of the injected dose per gram of tissue(%ID/g) and the ratio of Tumor/non-Tumor were calculated. 【Results】 The distribution of 125　 I -G9 in tumor at the third day was showed by autoradiography obviously higher th an in other organ/tissue (except blood) and the highest is at the 48 h. The T/NT values are 2-7. The autoradiography indicated that radioactivity concentrated in tumor tissue. The concentration in tumor edge is more obvious than in the ce nter. 【Conclusion】 125　I-G9 has a considerable targeting activity and can well locate in esophageal carcinoma tissue in tumor bearing nude mice.

Objective To innovate an early, rapid and efficient approach to the pmgnestic evaluation of sep-sis in order to lower the mortality. Method Forty-five septic rats, induced by cecal ligation and puncture, were divided into surviving group (n=23) and non-survival group (n=22) on six days after onset of sepsis. Serum samples were taken from septic and sham-operated rats (n=25) at 12 hours after surgery. HPLC/MS assays were performed to acquire the serum metabolic profiles, and radial basis function neural network (RBFNN) was em-ployed to build predictive model for prognostic evaluation of sepsis. Results The principal component analysis al-lows differentiating the rots of survive,non-survive and sham-operated from one another in respect of the pathologic characteristics. Six metabolites, linolenic acid, linoleic acid, oleic acid, stearic acid, docosahexaenoic acid and do-cosapentaenoic acid, related to the outcomes of septic rats were then structurally identified. A RBFNN model for outcome predication was built based upon the metabolic profile data from rat sera with the sensitivity of (96.1 ±3.6)% (n=10) and specificity of (91.0±4.3)% (n=10). Condusions HPLC/MS-based metabonomic approach combined with pattern recognition permits accurate outcome prediction of septic rats in the early stage. The proposed approach has advantages of rapid, low-cost and efficiency, and is isph-ing to be applied in clinical prognostic evaluation of septic patients.

Objective To analyze the clinic features and hereditary characteristics of three subtypes of porokeratosis, namely disseminated superficial actinic porokeratosis (DSAP), porokeratosis palmaris et plantaris disseminata(PPPD) and porokeratosis of Mibelli (PM) in five pedigrees with porokeratosis. Meth-ods After clinical and pathological diagnosis, every living family member of the five pedigrees with poro-kerotosis was undergoing medical examination and genetics analysis. These five pedigrees consisted of three DSAP pedigrees (totally 266 family members including 100 patients), and one PPPD pedigree (composing of 90 members including 26 patients), one PM pedigree (cornposing of 34 members including 17 patients). Results While diagnosed as porokeratosis, the five pedigrees included three distinctive variants, each with its own clinic characteristics. The lesions was initiated on the face in DSAP subtype, on palms and the flex-ion side of fingers in PPPD subtype; or involving sun-covered areas in PM subtype. Of the three subtypes of porokeratosis, the onset age in DSAP subtype was earliest, usually about 8-20 years old, about 14-20 years old in PPPD subtype, but PM subtype about 20-30 years old. Conclusions As a group of autosomal dominant genodermatosis, porokeratosis presented various clinic variants with different genetic basis. And, different subtype could be seen in a same patient or same pedigree.

Sodium/proton exchanger 1 (NHE1) plays an important role in the cardiomyocyte development. To study the effect of NHE1 activity in stem cells differentiation into cardiomyocytes, we treated P19 stem cells with dimethyl sulfoxide (DMSO) to initiate cardiomyocyte differentiation. In separate experiments, P19 cells were incubated with NHE1 specific inhibitor EMD87580 during the DMSO induction. The formed embryoid bodies (EBs) were detected with cell morphology detection, immunohistochemisty staining and RT-PCR analysis of expression of cardio-specific gene markers. Results showed that P19 cells were able to differentiate into cardiomyocytes and form the beating cell clusters. However, when cells treated with NHE1 inhibitor EMD87580, they could still form the EBs and proliferate when cell clusters adhered on the culture plate, but cells were unable to differentiate. This observation indicates that inhibition of NHE1 activity affected P19 stem cells differentiating into cardiomyocytes.
