Objective To evaluate the application of DNA image cytometry in screening cervical intraepithe-lial neoplasia and cervical cancer.Methods 80 patients with cervical intraepithelial neoplasia admitted during No-vember 2012 and November 2014 were involved in this study.The samples from all the patients were taken by cervix brushes and prepared for 2 slides:one for liquid-based cytology staining, read by cytologist, and the other for Thi-onin-Feulgen staining, tested by DNA image cytometry.The biopsy was performed with direction of colposcopy if one test was positive to verify the sensitivity and specificity of the two methods of staining.Results 70 cases were positive by DNA image cytometry and 27 ones were positive by liquid-based cytology.There was statistically signifi-cant difference in the sensitivity between the DNA image cytometry and the liquid -based cytology ( 94.8% vs. 38.8%;p<0.05), but no difference in the specificity between them (99.6%vs.99.8%).Conclusion Besides its good specificity, DNA image cytometry is more sensitive in screening cervical intraepithelial neoplasia and cervical cancer.

Objective To evaluate the variation of functional urethra length on urine control,explore a new method to prevent urinary incontinence and seek urodynamic evidence after radical prostatectomy. Methods Sixteen male dogs,matched in body weight,were randomly divided into two groups. Group A were used to test the different rest urethral pressure profile after resection of prostate,resection of distant prostate plus posterior urethra in length of 1.5 cm and 2.0 cm respectively; Group B to test the different rest urethral pressure profile on pedicle myotube in length of 2.0 cm and 1.0 cm using anterior bladder flap respectively after resection of prostate and posterior urethra in length of 2.0 cm. Results The urodynamic indexes fell off while the functional urethra length decurtated gradually in group A,but they went up in group B. The two groups showed significant difference before and after the resection of prostate and distant urethra in length of 2. 0 cm. Conclusion There was a direct ratio between the functional urethra length and the capability of urethral urine control. Reconstruction of functional urethra using anterior bladder flap pedicle myotube is a good choice to treat urinary incontinence after radical prostatectomy.

Objective:This study aimed to investigate the expression levels of centrosome-associated kinase Aurora-A, mutant type P53 (mt-P53), and c-myc in colorectal cancer. This study was also conducted to investigate the mutual relationship and functions of these factors in tumorigenesis and tumor progression. Methods:We examined the pathological specimens obtained from colorectal cancer, pericancerous tissues, and normal colorectal tissues by tissue microarray technique and immunohistochemistry (SP method) to determine the expression levels of Aurora-A, mt-P53, and c-myc proteins. The clinicopathological parameters were then analyzed. Re-sults: The positive rates of Aurora-A expression in normal colorectal tissues, pericancerous tissues, and colorectal cancer were 0%, 35%, and 69%respectively;by comparison, the positive rates of mt-P53 were 0%, 20%, and 57%, respectively. For c-myc, the positive rates were 0, 37%, and 76%, respectively. The expression levels of Aurora-A, mt-P53, and c-myc were significantly higher in tumor tis-sues than in normal colorectal tissues and pericancerous tissues (P<0.01). Aurora-A overexpression was related to the depth of invasion (P<0.05). Mt-P53 and c-myc overexpression was related to the depth of invasion, lymph node metastasis, and Dukes' classification (P<0.05). A strong positive correlation was observed between the expressions of Aurora-A, mt-P53, and c-myc in colorectal cancer (r=0.362, P<0.01; r=0.487, P<0.01). A strong positive correlation was also observed between the expressions of mt-P53 and c-myc in colorectal cancer (r=0.242, P<0.01). Conclusion:The overexpression of Aurora-A and c-myc and the mutation of P53 were important in tumorigenesis, tumor invasion, and metastasis of colorectal cancer. Thus, the co-detection of Aurora-A, mt-P53, and c-myc may be useful for the early diagnosis and prognosis of colorectal cancer.

To study the cartilage differentiation of mouse mesenchymal stem cells (MSCs) induced by cartilage-derived morphogenetic proteins-2 in vitro, the MSCs were isolated from mouse bone marrow and cultured in vitro. The cells in passage 3 were induced into chondrogenic differentiation with different concentrations of recombinant human cartilage-derived morphogenetic proteins-2 (0, 10, 20, 50 and 100 ng/mL). After 14 days of induction, morphology of cells was observed under phase-contrast microscope. Collagen II mRNA and protein were examined with RT-PCR, Western blotting and immunocytochemistry respectively and the sulfate glycosaminoglycan was measured by Alcian blue staining. RT-PCR showed that CDMP-2 could promote expression of collagen II mRNA in an dose-dependant manner, especially at the concentration of 50 ng/mL and 100 ng/mL. Immunocytochemistry and Western blotting revealed a similar change. Alcian blue staining exhibited deposition of typical cartilage extracellular matrix. Our results suggest that mouse bone marrow mesenchymal stem cells can differentiate into chondrogenic phonotype with the induction of CDMP-2 in vitro, which provides a basis for further research on the role of CDMP-2 in chondrogenesis.

Objective To explore the correlation of the indoor carbon monoxide concentration and chronic diseases by monitoring the indoor carbon monoxide concentration timely.Methods Collected the data of non-traumatic patients(n=80)from July 201 1 to January 2014,and assigned them into the experiment group with carbon monoxide concentration measured and the control group without measured.All the subjects were further divided into one group with complaint of carbon monoxide poisoning and the other one without.For patients exposed to high concentration of carbon monoxide,carboxyhemoglobin was also measured and APACHEⅡ was scaled,and the relationship between them was analyzed.The confirmation and misdiagnosis rate of carbon monoxide poison-ing were calculated.For the patients with acute exacerbation of chronic diseases like chronic cardiac failure,chronic obstructive pul-monary disease,cerebral infarction induced by carbon monoxide poisoning,BNP,CAT and NIHSS were documented on admission and during follow-up with removal of carbon monoxide exposure and compared respectively.Results The relationship between blood carboxyhemoglobin,APACHEⅡ scores on admission and indoor carbon monoxide concentration was linear,and obviously positive.Between the experiment group(n=40)and the control group(n=40),there was significant difference(P <0.05)in confirma-tion rate and misdiagnosis rate with 80.00% vs.55.00% and 6.25% vs.81.80% respectively.For the 54 patients with carbon monoxide poisoning diagnosed,the changes between before and after removal of carbon monoxide exposure of the CAT scores of chronic obstructive pulmonary disease and NIHSS score of CI disease and myoglobin,troponin I,creatine kinase isoenzyme,BNP for chronic cardiac failure were significantly different(P <0.01).Conclusion The indoor carbon monoxide concentration may indicate the severity of carbon monoxide poi-soning,which could increase the confirmation rate of carbon monoxide poisoning,and reduce the misdiagnosis rate.It is helpful to identify carbon monoxide exposure,the common inducing factor,so as to improve the patients′clinical symptoms.

OBJECTIVETo compare the effects between mild moxibustion and specific electromagnetic spectrum therapy apparatus (TDP) for obsolete collateral ligament injury of interphalangeal joints.

METHODSSixty patients were randomly divided into a mild moxibustion group and a TDP group, 30 cases in each one. In the mild moxibustion group, pure moxa sticks were used at the affected digital joints locally for 20-30 min a time. In the TDP group, TDP was applied at the affected digital joints locally for 20-30 min a time. The treatment was given once a day for two courses, and 10-day treatment was made into a course. Visual analogue scale (VAS) for pain, swelling degree of the affected digital joints before and after treatment were observed and the clinical efficacy and safety were evaluated in the two groups.

RESULTSThe excellent rate was 56.7% (17/30) and the excellent and, good rate was 83.4% (25/30) in the mild moxibustion group,which were better than 36.7% (11/30) and 76.7% (23/30) in the TDP group respectively (both P < 0.01). After treatment the score of VAS and digital joints swelling degree were improved than those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements of the mild moxibustion group were better than those of the TDP group (P < 0.01, P < 0.05).

CONCLUSIONMild moxibustion can apparently relieve the painful and swelling degree of obsolete collateral ligament injury of interphalangeal joints, which is superior to TDP.
