OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

0.05)and the TNM staging (P=0.55).A mild elevated compared other pathological classification was found in small cell lung cancer (0.191?0.275).Conclusions The results showed that RFQ-PCR was suitable for measurement of the mRNA level of PLKI in bronchoscopic bioptic specimens.This study suggest elevated expression of PLK1 might play a important role in development of lung cancer,so that PLK1 might be a potential tumor marker for Lung cancers.Advanced studies will be needed to clarify that PLKI mRNA level do not relate to TNM staging and pathological classification.

Objective: To explore the correlation between moxibustion sensation and distance of moxa stick and provide reference for clinical practice. Methods: A total of 16 healthy volunteers aged 18-35 years old in college were recruited and given mild moxibustion at Shousanli (LI 10), Zusanli (ST 36), Shenshu (BL 23) and Tianshu (ST 25) with moxa stick, and the occurrence and frequency of moxibustion sensation were recorded at distances of 5 cm, 4 cm, 3 cm and 2 cm. Mild moxibustion scale was used to count the score. Results: Warm was the main moxibustion sensation, burning pain and soreness decreased with the rise of distance; for the same acupoint, score of mild moxibustion scale increased with the decrease of distance; score ranged between 5.5 and 6.5 at distance 3 cm, which was the most comfortable distance for volunteers. Conclusion: The distance of 3 cm is the most comfortable distance in mild moxibustion.

OBJECTIVE: To explore the multidrug resistance (MDR) mechanism of ABC superfamily transporters in the tumor stem cells(TSC) from human brain glioma tissues. METHODS: Samples of glioma were obtained from 30 patients undergoing microsurgical tumor resection. The CD133(+) cells and CD133(-) cells from these tumor specimens were isolated by magnetic activated cell sorting(MACS). These cells were cultured, proliferated and passaged. The protein and activity expression of multidrug-resistance protein 1(MDR1) and multidrug-resistance associated protein 1(MRP1) were analyzed between CD133(+) and CD133(-) cells by immunocytochemistry and RT-PCR respectively. RESULTS: CD133(+) cells generated free floating neurosphere like brain tumor spheres(BTS) and abnormal proliferating capacity in the serum-free medium(SFM) in vitro. Three cases from glioblastoma stem cells could form BTS in the complete medium, and could be cultured for 1-3 passages. The range of positive cell proportion for MDR1 and MRP1 expression in CD133(+) cells was 18%-67% and 23%-73% respectively. The expression levels of MDR1 and MRP1 mRNA were higher in CD133(+) glioma stem cells than those in the differentiated tumor cells(TC), the protein activity was increased to 16.1 and 19.6 times respectively compared with that of TC. The protein and activity expression were positively related to the pathological grades of tumors. MDR1 or MRP1 drug resistance was not expressed in all the tumors and there was obvious correlation between MDR1 and MRP1. CONCLUSION Only a small proportion of cells in the heterogeneous glioma is CD133(+) brain tumor stem cells which display the strong capacity of self-renewing, abnormal proliferation and intrinsic multidrug resistance to traditional chemotherapy. The high expression of MDR1 and MRP1 by the CD133(+) brain tumor stem cells is one of the main mechanisms in the chemoresistance of tumors. CD133(+) brain tumor stem cells can be served as the root of multidrug resistance and key therapeutic target for glioma chemotherapy.

OBJECTIVETo solve the problems in the accuracy and standardization of short tandem repeats-polymerase chain reaction (STR-PCR) typing, the authors adopted the molecular clone technology in producing the standard allelic ladders of D1S1676, D2S2735, D11S1977 and D22S444 loci and applied them in a population study on the Hans in Chengdu, China.

METHODSPCR was used to produce several different allelic fragments of these loci. PCR products were eluted from the gel and re-amplified by PCR. The purified allelic fragments were then blunt-end subcloned individually into the pGEMR-T plasmid vectors and the recombinant were transfected into competent E.coli DH5alpha TM cells. The results of sequencing confirmed that the size and the construction of the inserts were correct. The recombinant plasmids DNA with the inserts were then used as template for re-amplification to generate the four loci standard ladders.

RESULTSThe authors succeeded in producing large quantity of standard allelic ladder of these four loci, with which the genetic polymorphisms of these loci in Chengdu Han population of China were studied.

CONCLUSIONThis method is of high value for forensic DNA typing to construct standard ladders. D1S1676, D2S2735 loci are robust for forensic analysis in Chinese Han population, whereas the value of D11S1977 and D22S444 loci is limited.

OBJECTIVETo formulate recommendations in the evaluation of results of genetic analyses in paternity testing under considering mutations.

METHODSA total of 15 short tandem repeat(STR) loci were employed for this study, which were included CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, PentaD and PentaE. Both 100 cases of true trio and 100 cases of false trio were investigated.

RESULTSThe numbers of mismatch alleles in different STR loci were observed in 100 cases of false trio. The different distributions of paternity index were obtained, including the changes of paternity index in each case of true trio under simulated mutations.

CONCLUSIONIn order to avoid the effect of mutations, the exclusion of paternity was never considered on the basis of a single locus. The threshold values of the combined probability of exclusion and the paternity index were important for both exclusion and inclusion of paternity. The scientific evidence for paternity testing can be obtained when both the combined probability of exclusion and the paternity index meet the threshold values. However, when either the combined probability of exclusion or the paternity index can not meet the threshold values, more genetic markers should be added.
