1.Fragile histidine triad transcription abnormalities and human papillomavirus16 infection in human cervical carcinoma
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(02):-
Objective To evaluate the relationship between fragile histidine triad(FHIT) transcription abnormalities and HPV16 infection and human cervical tumorigenesis.Methods Total RNA from 5 cervical carcinoma cell lines(SiHa,HeLa,RJC-1,CS1213 and C4-1),58 primary cervical cancer specimens and 18 normal cervical epithelial tissues were extracted and FHIT transcripts were characterized by a two-step(nested) reverse transcription(RT)-PCR.The seven of the PCR products with different size were purified and sequenced.HPV16 infection was assessed by PCR.Results ① There were altered FHIT transcripts in SiHa,HeLa and C4-1 cells.Aberrant FHIT transcripts were detected in 39 out of the 58 cervical cancer samples(67.2%),but none out of 18 in the normal cervix tissue specimens(0%);HPV16 infections were identified in 37 of the 58 cervical cancer tissues(63.8%),but 1 in the 18 normal cervical epithelial tissues(5%),which showed a significant difference between these two groups(P0.05).③ The exon 5 and exon 6 were mainly deleted in the altered FHIT transcripts and no insertion and point mutation were found by DNA sequencing.Conclusion Aberrant FHIT expression was significantly common in cervical cancers and was correlated with HPV16 infection.These findings suggest that the tumor suppressor gene FHIT and high risk HPV16 may play a very important role in human cervical carcinogenesis.

Muscle recently has been identified as a good source of adult stem cells that can differentiate into cells of different lineages.Researchers have identified two types of stem cells in skeletal muscle.Further research is necessary to delineate the relationship between different populations of musclederived stem cells(MDSCs)and between MDSCs and other adult stem cells.The methods used to isolate these cells appear to influence the stem cell characteristics.As these efforts continue,the potential for MDSCsbased therapy for other musculoskeletal injuries,as well as for cardiac and smooth muscle injuries,is currently being explored.The behavior,biocharacteristic,isolation,differentiation and the probability of application to regenerate lost or diseased tissue of MDSCs were summarized.

Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.

OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.
METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.
RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).
CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

Objective To compare the clinical efficiency of two methods in the open surgery treatment of seconda-ry common bile duet stones: transeytie common bile duet exploration with eholedoehoscope (TCBDE),or traditional eholedoehotomy with T-tube drainage.Methods Retrospectively analysis the treatment of 113 eases with secondary bile duet stones (TCBDE group 58 cases ,T-tube group 45 cases) ; Compare the achievement ratio,operating time; complications,average hospital stay and cost between two groups.Results All procedure is successful,without any severe complications.There are no significant differences of operating time.The TCBDE group has sig-nificantly shorter hospital stay and lower cost.Conclusion TCBDE has significant advantages than the traditional choledochotomy,and should be the predominant method in the open surgery of secondary common bile duet stones.
