Objective To develop the human colon carcinoma(HT-29) liver metastasis model in nude mice,and to detect the expression of human telomerase reverse transcriptases(hTERT) mRNA in liver of nude mice. Methods Liver metastases were established in 30 Balb/c nude mice by intrasplenic injection of colonic cancer cells(HT-29),and the spleens were resected.After being sacrificed,the tumor growth was observed,and the pathological examinations were performed.The expression of hTERT mRNA in the livers of nude mice was detected by RT-PCR technique. ResultsHuman colon carcinoma(HT-29) liver metastasis model was developed in all the 30 nude mice,with the liver metastasis rate of 100%.The pathological results revealed the occurrence of liver metastases,and the expression of hTERT mRNA was positive in the liver tissues. Conclusion Intrasplenic injection of HT-29 cell is a reliable way for producing colonic cancer liver metastasis model,and the positive expression of hTERT mRNA in liver tissues indicates the significance of hTERT in the early diagnosis and treatment of colon carcinoma liver metastasis.

Central composite design (CCD) is one of the most commonly used design methods in response surface optimization and has been widely applied in the field of pharmaceutics to optimize preparations. On the 20th anniversary of the introduction of CCD into China, the paper reviews its application in domestic pharmaceutical researches. Based on the brief introduction of basic principle and operation steps of CCD, the mistakes emerging in the application of CCD are summarized, including conceptual confusion with Box-Behnken design and face-centered CCD as well as wrong designs. Besides, the issues concerning the selection of factors and responses are discussed. The article is helpful for researchers to comprehensively understand the CCD and facilitates the rational application of this method.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

The synthesized full-length hGLP-1 gene was cloned into pET-32a(+) to get the recombinant plasmid pET32-GLP-1, which could express a fusion protein containing thioredox, hexahistidine, and rhGLP-1 consecutively. The recombinant plasmid containing hGLP-1 was transformed into E.coli BL21 (DE3) and expressed by IPTG induction. The fusion protein was purified from lysates with Ni?IDA His?Bind affinity chromatography. rhGLP-1 with the purity of 90% was achieved after enterokinase digestion, Ni?IDA His?Bind affinity chromatography again, then was concentrated by ultrafiltration. The purified rhGLP-1 showed a single band on IEF gel with an isoelectric point between pH5.2 and pH5.85. ESI mass spectrometry showed that the molecular weight was 3355.0kDa as expected. rhGLP-1 was digested with trypsin followed by mass analysis and the peptide mapping produced two expected fragments with the molecular weights of 2097.7kDa and 1005.5kDa, respectively. The purified rhGLP-1 also showed obvious biological activity for both lowering plasma glucose and stimulating insulin secretion in mice.

0.05).The effective rates of patients with recurrence or metastasis were respectively 92%(12/13) and 7/9.The rate of acute radiation reaction of the rectum between the treatment group and control group were respectively 46%(13/28)and 80%(24/30),with a significant difference(P0.05),while the rate of severe bone marrow depression between two groups showed a significant difference(0 and 13%,P 0.05).Conclusion The therapeutic effect of 3DCRT is similar to that of traditional radiotherapy in the treatment of cervical carcinoma,but the former treatment method has a lower rate of acute complications.

OBJECTIVETo investigate the efficacy of biofeedback therapy for fecal incontinence in patients with mid or low rectal cancer.

METHODSTwenty-four patients with mid or low rectal cancer received biofeedback treatments after restorative resection and therapeutic efficacy was evaluated using anorectal manometry and Vaizey and Wexner scoring systems. Eighteen inpatients without defecating difficulties were selected as control group.

RESULTSThe parameters of anorectal manometry in patients with rectal cancer were significantly lower than those in the control group (P<0.01). After biofeedback therapy, the maximum squeeze pressure, resting pressure and maximum tolerated volume were significantly increased, from (118.3+/-42.9) mm Hg to (193.2+/-38.2) mm Hg, (27.8+/-9.0) mm Hg to (47.9+/-9.3) mm Hg,(97.5+/-52.8) ml to (189.1+/-39.0) ml, respectively (all P<0.01), while no significant difference in sensory threshold was observed (P=0.101). Post-treatment Vaizey (10.5+/-2.3 vs 12.9+/-2.8) and Wexner (7.5+/-2.5 vs 10.1+/-2.6) scores were significantly decreased compared with those before biofeedback (P<0.01).

CONCLUSIONBiofeedback therapy can improve the anal function in patients with rectal cancer after restorative resection.
