Objective: To compare the efficacy of casein phosphopeptide-amorphous calcium phosphate nanocomplexes (CPP-ACP) and Duraphat varnish on preventing radiation caries and dentin hypersensitivity (DH) in irradiated head and neck cancer pa-tients. Methods:A total of 112 patients with head and neck cancer who will undergo radiotherapy were selected and randomly divided into the CPP-ACP group (experimental group) and the Duraphat varnish group (control group). A day prior to the scheduled radiothera-py, CPP-ACP containing paste had been applied once a day for 5 weeks to the teeth surface of the experimental group. Duraphat varnish was applied with the same frequency in the control group. The decay missing filling tooth (DMFT), decay missing filling surface (DMFS), and DH of two groups before radiotherapy and 12 months after radiotherapy were observed and statistically analyzed. Re-sults:Before radiotherapy, DMFT, DMFS, and DH showed no significant differences between the groups (P>0.05). However, signifi-cant increase in DMFT, DMFS, and DH was noted in the two groups 12 months after the radiotherapy (P<0.05). A higher increase was observed in the DMFT, DMFS, and DH of the control group compared with those in the experimental group (P<0.05). Conclusion:CPP-ACP effectively reduced radiation caries and sensitivity in irradiated head and neck cancer patients and deservesclinical applica-tion.

BACKGROUND:Mesenchymal stem cels can secrete a variety of cytokines and growth factors that promote the survival of surrounding cels and play a paracrine role. OBJECTIVE:To investigate the effect of human umbilical cord mesenchymal stem cels on the proliferation and apoptosis of ectopic endometrial cels. METHODS:After isolation and culture, human umbilical cord mesenchymal stem cels and ectopic endometrial cels were co-cultured as observation group, and ectopic endometrial cels cultured alone served as control group. At 24, 48, 72 hours of culture, the proliferation and apoptosis of ectopic endometrial cels were detected by MTT and flow cytometry, respectively; RT-PCR was used to measure the expression ofPTEN gene in ectopic endometrial cels. RESULTS AND CONCLUSION:At 24, 48 and 72 hours, the proliferation of ectopic endometrial cels in the observation was inhibited significantly as compared with the control group, and the hypodiploid peak ratio also increased significantly (P < 0.05). Over time, the cel inhibition rate was gradualy declined, and there were significant differences at different time points (alP < 0.05). Compared with the control group, the expression of PTEN gene was up-regulated significantly in the observation group (P < 0.05). In the observation group, the expression ofPTEN gene at 48 and 72 hours was significantly higher than that at 24 hours (P < 0.05). These findings indicate that in the human umbilical cord mesenchymal stem cels can inhibit the proliferation of ectopic endometrial celsin vitro and promote their apoptosis by up-regulation ofPTEN mRNA expression.

OBJECTIVE:
To determine if greater efficacy could be achieved with the intranasal antihistamine azelastine and the intranasal corticosteroid fluticasone propionate used concurrently in the treatment of nasal obstruction of persistent non-allergic rhinitis.
METHOD:
A total of 162 persistent non-allergic rhinitis cases with moderate to severe nasal obstruction were randomized to treatment with the following: the combination therapy or nasal corticosteroids monotherapy. Efficacy was assessed by change from baseline in nasal obstruction score at week 2 and week 6 visits. The perceptions of global treatment satisfaction(convenience, side effects, cost and effectiveness) in both groups were analyzed.
RESULT:
In both groups, the nasal obstruction score assessment descended significantly at week 2 and week 6 visits versus at baseline (all P < 0.01). At week 2 and week 6 visits, the nasal obstruction score in the combination therapy groups were significantly improved than that in nasal corticosteroids monotherapy groups (all P < 0.01). The perceptions of global treatment satisfaction in the combination therapy groups were significantly better (P < 0.05).
CONCLUSION
Azelastine nasal spray and intranasal corticosteroid in combination may provide a substantial therapeutic benefit for patients with persistent non-allergic rhinitis, especially nasal obstruction. The combination therapy was well tolerated and safety.

Objective To explore the risk factors ,prevention and treatment of the occurrence of perirenal hematoma after flexible lithotripsy. Methods We retrospectively analyzed the clinical data of 18 patients with symptomatic perirenal hematoma from 1259 who had undergone ureteral flexible lithotripsy in our hospital during the period of April 2007 to April 2016. Of the 18 patients,7 were complicated with diabetes mellitus,11 had urinary tract infection;15 were female,and 3 were male. Results Perirenal hematoma was confirmed by B ultrasound and CT,which situated on the Posterolateral side of the kidney in 8 patients,and on the lower pole and abdominal side in 10. Hematoma depth was 2.6-15.3 cm(average was 5.2 cm). The hematoma?related symptoms gradually disappeared in 11 patients 7 to 14 days after they received conservative treatment. 5 recovered gradually 15 days after undergoing hematoma puncture and drainage ,and 2 recovered 36 days after receiving open surgery for removal of hematoma. Conclusions Female,diabetes,urinary tract infection,bigger stone size,prolonged surgical duration,and infected stones were the risk factors for perinephric hematoma related to ureteroscopic lithotripsy. Full preoperative preparation ,effective anti?infection ,intraoperative improvement of calculus?breaking skills and use of large caliber semirigid through sheath,low pressure perfusion,shorter surgical duration,and staging surgery are effective ways to reduce the occurrence of perirenal hematoma.
