BACKGROUND:Several studies have shown that Hero642 is a rotary nickel-titanium file with high safe performance, and its ability of root canal shaping is good.
OBJECTIVE:To observe the clinical effect of single-visit root canal treatment using Hero642 nickel-titanium rotary instrument on teeth with chronic pulpitis and apical periodontitis.
METHODS:Total y 400 teeth with chronic pulpitis and apical periodontitis were operated by Hero642 nickel-titanium rotary instrument and nickel-titanium hand file, respectively. The efficiency of root canal preparation was taken. Pain reactions were recorded 1 week after operation and curative effects were evaluated 2 years after root canal treatment. Rates of pain and success were calculated at 1 week and 2 years after treatment, respectively.
RESULTS AND CONCLUSION:The average time for root canal preparation was (3.57±0.76) minutes in the Hero642 group and (7.62±0.25) minutes in the hand file group, and there was a significant difference between the two groups (P<0.01). After 1 week of treatment, the pain rates were 3.5%and 22.8%in the two groups, respectively, showing a significant difference (P<0.01). Two-year fol ow-up was performed, and ratios of success were 94.4%in the Hero642 group and 92.4%in the hand file group, but there was no difference between the two groups. Hero642 nickel-titanium rotary instrument for single-visit root canal treatment showed excellent efficiency on clinical treatment, reduced treatment period and had less postoperative reactions.

AIM To study the influence of indapamide(Ind) on pharmacokinetics of telmisartan(Tel) and observe the difference between male and female rats. METHODS Wistar rats were divided into Tel and Tel+Ind groups, each group containing 8 female and 8 male rats, and were ig administered a single dose of either Tel 3.6 mg·kg-1 or Tel 3.6 mg·kg-1+Ind 0.135 mg·kg-1, respectively. Blood samples were collected at intervals over 96 h after administration. The Tel concentrations in plasma were determined by high performance liquid chromatography with fluorescence detector. The Tel concentration-time curves were simulated by 3p97 software and the pharmacokinetic parameters were calculated. RESULTS Whatever in female or male rats, there were no significant differences in the main pharmacokinetic parameters of Tel between Tel and Tel+Ind groups. However, females had higher values for area under the concentration-time curve and maximum plasma concentration than males, but lower values for total clearance in both Tel and Tel+Ind groups. CONCLUSION Ind has no significant influences on the pharmacokinetics of Tel. However, pharmacokinetics of Tel is significant different between male and female rats.

[Objective] To investigate the effect of naringin at different doses on the neuropathie pain produced by lumbar 5 spinal nerve ligafion (L5 SNL). [Methods] Using the method of behavioral test, we tested the 50% paw withdrawal threshold before and after intragastrieal application of naringin in the rats with L5 SNL. [Results] Naringin at 30, 90, 100 mg/kg but not at 10 mg/kg increased the 50% paw withdrawal threshold of 1.5 SNL rats significantly. Single application of Naringin (at 30 or 90 mg/kg) inhibited mechanical allodynia for around 6 hours, and the inhibitory effect persisted for 4 days after the cessation of the drug when naringin (30 mg/kg, daily) was consecutively applied for 7 days. [Conclusion] Intragastrical of naringin could relieve the neuropathic pain produced by peripheral nerve injury.

Objective To re-evaluate the prognostic value of the 6th edition of UICC/AJCC staging system in patients with nasopharyngeal carcinoma (NPC) treated with intensity-medulated radiation therapy (IMRT). Methods From February 2001 to March 2007, Clinical data of 570 NPC patients initially treated with IMRT in Cancer Center of Sun yat-sen University were reviewed and the long-term survival was analyzed according to T, N and overall stages. Results The median follow-up was 42 months. 184 patients were followed up to 5 years. The 5-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and overall survival (OS) of the whole group were 93. 0%, 85.4% and 83. 3% ,respectively. No statistically significant difference of LRFS was detected between the either two of stage T_1, T_(2a) and T_(2b)(100%, 100% and 94. 5% ;T_1 vs. T_(2b), χ~2 = 1.92, P =0. 166 ;T_(2a) vs. T_(2b), χ~2= 0. 35, P =0. 555), stage T_(2b) and T_3 (94. 5% and 91.3% ;χ~2 = 2. 62, P = 0. 106), or stage T_3 and T_4 (91.3% and 89. 5% ; χ~2 = 1.55, P =0. 214). The 5-year DMFS of stage N_2 was similar with stage N_1 or stage N_3(80. 2%, 86. 2% and 61. 4% ; N_2 vs. N_1, χ~2=2.22, P=0.136;N_2 vs. N_3, χ~2= 1.92, P=0.165). No statistically significant difference of 5-year OS was observed among stage Ⅰ , Ⅱ_a and Ⅱ_b(91.7%, 100% and 95. 3% ; Ⅰ vs. Ⅱ_b χ~2 =0.32, P=0.574;Ⅱ_a vs. Ⅱ_b,χ~2-0.25, P=0.617), or between Ⅳ. And Ⅳ_b(67.9% and 75. 0% ;χ~2 = 0.25, P = 0. 616). Conclusions The 6th edition of UICC/AJCC staging system shows poor predictive value for the long-term survival of NPC patients treated with IMRT.
