BACKGROUND: Studies have demonstrated that trehalose possesses protective effects on cyropreserved sternum. But the mechanism of action remains poorly understood. OBJECTIVE: To investigate the effects of trehalose on bcl-2 and bax mRNA expression in cryopreserved sternum. METHODS: Four groups of freshly prepared solution were used: low-potassium dextran (LPD), LPD + dimethyl sulfoxide (DMSO), LPD + trehalose, LPD + DMSO + trehalose. Rat sternum was cut and then immediately cryopreserved in the tubes containing each group of solution. Fresh rat sternum tissue and 4 groups of samples cryopreserved for 120 days were taken and bcl-2 and bax mRNA expression in fresh and cryopreserved sternum was detected using reverse transcription-polymerase chain reaction.RESULTS AND CONCLUSION: bcl-2 mRNA expression in the LPD + trehalose group was significantly higher, but bax mRNA expression was significantly lower, than in the LPD, LPD + DMSO groups (both P < 0.01). LPD + DMSO + trehalose group showed highest bcl-2 mRNA expression and lowest bax mRNA expression, which were basically similar to fresh bone tissue (P > 0.05). These findings indicate that trehalose may protect cell activity in cryopreserved sternum by enhancing bcl-2 mRNA expression and inhibiting bax mRNA expression, and trehalose together with DMSO shows better protective effects.

Objective To investigate the clinical effects and complications of uterine artery embolization (UAE) therapy using different embolic agents in treating uterine adenomyosis. Methods During 2004—2011, a total of 45 female patients with uterine adenomyosis were admmitted to authors’ hospital to receive uterine artery embolization therapy. The embolic agents used in the procedures included domestic iodized oil, sodium alginate microspheres and Embosphere microspheres. The patients were randomly divided into group A (n=15, using domestic iodized oil as embolic agent), Group B (n=13, using sodium alginate microspheres as embolic agent) and group C (n = 17, using Embosphere microspheres as embolic agent). After the treatment, all the patients were followed up for over 2 years, focusing on the observation of the clinical symptoms such dysmenorrheal, changes of MRI signs and severe complications. The results were analyzed and compared among the three groups. Results After UAE, the clinical symptoms such as the degree of dysmenorrhea, menstrual quantity, etc. were improved in all patients. Six months after UAE, the obvious remission rate of dysmenorrheal in group A, B and C was 33.3% (5/15), 30.8% (4/13) and 41.1%(7/17) respectively. Twelve months after UAE, MRI scanning showed that the uterine sizes in group A, B and C were reduced to 49.19%, 48.25% and 50.05% respectively. Follow-up examination at 24 months after UAE showed that recurrence of dysmenorrheal in group A, B and C was seen in 2, 4 and 2 cases respectively, and amenorrhea was seen in 2 cases of group A and one case in group C. Conclusion The use of domestic iodized oil, sodium alginate microspheres or Embosphere microspheres as embolic agents in performing super-selective uterine artery embolization for adenomyosis can effectively relieve the degree of dysmenorrheal, decrease the uterine size. In addition to ovarian dysfunction, the uterine cavity adhesion may be also a possible cause of amenorrhea occurring after UAE may. In order to ensure a similar clinical efficacy, the use of granular solid embolic agent is preferred as its safety is possibly higher than the liquid embolic agents.

[Abstract ] Objective Pelvic radiation disease(PRD) is multiple injuries in more than one organ resulted by pelvic radio-therapy.Patients have the symptoms of frequent feces and fecal incontinence after the resection of small bowel lesion .Sugeries on PRD patients were mainly distal ileum and ilieocecal valve resections , while the most susceptible part of pelvic radiation injury is rectum . However , little research has been done concerning PRD patients′anorectal functions .This study was mainly to evaluate the anorectal function of cervical cancer patients with PRD in order to provide evidence for the therapy and prognosis of PRD . Methods Cervical cancer patients with PRD in need of small bowel resection who hospitalized in our department from January 2014 to January 2015 were collected as patient group , while people from outpatient physical exam group were selected as control group according to the exclusion criteria of hypertension , diabetes, constipation and unrelaxed pelvic floor syndrome .PDR group and control group were matched according to age.All subjects underwent colonoscopy and anorectal manometry .Rectal radiation injury was estimated on the basis of colonoscopy results.Anorectal manometry results of PRD group and control group were analysised statistically . Results PRD group and control group both included 20 women without stenosis or obstruction in rectum .Significant difference was found between PRD group and con-trol group in anal resting pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.05), anal maximum squeezing pressure (47.23 ±9.08 mmHg vs 58.25 ±9.24 mmHg, P<0.01), anal distension pressure (23.30 ±12.49 mmHg vs 39.10 ±9.99 mmHg, P<0.01), rectal defecation pressure(22.85 ±16,69 mmHg vs 50.90 ±9.14 mmHg, P<0.01) and maximum tolerated rectal volume (112.85 ±51.34 mL vs 173.50 ±48.15 mL, P<0.01).There was no significant difference between the two groups as to the lenghth of functional sphincters(P=0.313),rectum initial threshold(P=0.416) and rectal defecation threshold(P=0.161). Conclusion Ionization radiation that injures PRD patients′internal anal sphincters and external anal sphincters also reduces maximum tolerated rec -tal volumes preoperatively .It′s necessary to assess the muscles and nerve functions of anorectum before intestinal surgery in order to make a proper operation plan which will improve PRD patients′life quality.
