2.A novel technique for micro-reconstruction of posterior wall of external auditory canal and tympanum in patients with chronic supprative otitis media using pedicled temporalis myofascia
Chinese Journal of Microsurgery 2013;36(6):553-557
Objective To explore a novel surgical treatment for chronic suppurative otitis media (CSOM) and evaluate its treatment effect.Methods All 97 patients with chronic suppurative otitis media were chosen to be treated using this new surgical method.The skin of the external auditory canal was maintained intact.Open radical mastoidectomy was used to complete clean-up lesions ; the fascia of pedicled temporalis myofascia (PTM) was used to repair the tympanic membrane.The pedicled temporalis fascia,pedicled postauricular periosteal flap and intact skin of the external auditory canal were used in reconstruction of the posterior wall of external auditory canal.Pure tone audiometry (PTA) was performed before and after surgery,recording the air conduction and bone conduction thresholds at 0.5 kHz,1.0 kHz,2.0 kHz,4.0 kHz.The average of the patient's air and bone conduction hearing thresholds was recorded at the 4 frequencies.External auditory canal gauze was removed 3 weeks after surgery.All subjects were followed up for over 2 years.Comparison of hearing thresholds (PTA) was made ① Before and 4 weeks after surgery.② Before and 2 years after surgery.Hearing function comparison include air conduction (AC),bone conduction (BC) and air-bone gap (ABG) analysis.SPSS 16.0 was used in statistical analysis.Pre-and postoperated AC,BC and ABG were compared using T-test.P < 0.05 was considered statistically significant.Results The healing rate of post-operated tympanic membrane was 95.88% (93/97).Ninty-six ears had 2-year follow-up,and 1 patient was lost in follow-up.There were 2 patients presented with eardrum perforation during the follow-up,and the 2-year healing rate of tympanic membrane perforation was also 93.85% (92/97).In 96 ears with 2-year followed-up,the average of pre-AC was (52.10 ±3.96) dB,the average of post-AC was (35.67 ±2.52) dB; the average of preABG was (36.6 ± 5.2) dB,and the average of post-ABG (± SD) was (12.14 ± 6.20) dB.Statistical analysis showed significant difference between preoperative and postoperative AC or ABG values (P < 0.05).Conclusion The present surgical procedure broke through the existing conventional mastoidectomy of making a surgical incision in the posterior wall of the external auditory canal.This procedure cleared the lesion completely and preserved the physiological function of the external auditory canal.The acoustic systems and state of gasification to the mastoid tymnpanum were reconstructed,rehabilitated and maintained.The healing rate of hearing and tympanic membrane perforation was improved.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(15):1137-1141
OBJECTIVE:
To investigate the optimizing conditions in isolation of the side population in laryngeal carcinoma cell line Hep-2.
METHOD:
Single-cell suspension cells were detached from the culture flask with trypsin EDTA, at a concentration of 1 x 10(6) cells/ml. (1) The trail Samples were incubated with Hoechst33342 at a concentration of 5 microg/ml, 9 microg/ml, 10 microg/ml, 11 microg/ml for 90 minutes. (2) They were incubated with Hoechst for 50, 70, 90, 110, 130 min in water bath individually. (3) The single-cell suspension were incubated Hoechst in water bath and in thermostat each. (4) The two different density of cells were harvested, which were 100% and 70%, and then di gest into single-cell suspension. Once incubation finished, suspended in phosphate buffered saline (PBS), then test SP% by flow cytometry. Among all groups,Verapamil hydrochloride was added to the control samples, incubated at 37 degrees C for 30 minutes, the other condition were keep the same with their trial groups.
RESULT:
(1) The percentage of Hoechst-negative cells in trial group was (39.96 +/- 0.24)%, (26.23 +/- 0.39)%. (18.79 +/- 0.02)%, (19.01 +/- 0.14)% at the concentration of 5 microg/ml, 9 microg/ml, 10 microg/ml, 11 microg/ml respectively, when the PI-positive cells were (30.45 +/- 0.63)%, (49.9 +/- 0.42)%, (50.12 +/- 0.68)%, (64.16 +/- 0.39)% separately. (2) Varying the duration of staining incubation showed that there was a typical FACS pattern and SP% was constant when the incubation was at least 90 min. (3) Compare to water bath, SP% was more than in thermostat, the SP% was (18.67 +/- 0.45)%, (22.6 +/- 0.50)% respectively; (4) Cell density is also responsible for SP%. The low density the cell is, the less in SP%. SPSS13.0 was used in statistical analysis, the groups were compared using t-Test. P < 0.05 was considered statistically significant.
CONCLUSION
The optimum concentration and duration of incubation of Hoechst33342 in isolation of the side population cells in laryngeal carcinoma cell line Hep-2 is 10 microg/ml and 90 min. Incubated in water bath is better than in thermostat. The best staining cell density is around 80%-90%.

Chinese Acupuncture & Moxibustion 2014;34(4):337-340
OBJECTIVETo observe the difference in clinical efficacy on focal vitiligo treated with heat-sensitive moxibustion in comparison with medication, and discuss its effect mechanism.
METHODSSixty-eight cases were randomized into a moxibustion group (38 cases) and a medication group (30 cases). Additionally, 20 healthy persons were selected randomly as a normal group. In the moxibustion group, the heat-sensitive moxibustion was applied to Hegu(LI 4), Quchi(LI 11), Yanglingquan(GB 34), Zusanli(ST 36), Xuehai(SP 10) and the others, once a day. In the medication group, triamcinolone acetonide cream was used externally and locally, twice a day. In the two groups, the treatment of 15 days made one session. The efficacy was observed after continuous treatment for 3 sessions. The hemorheology test was done in all of the subjects. The radioimmunoassay was adopted to determine the levels of Interleukin 2 (IL-2), Interleukin 6 (IL-6), Interleukin 10 (IL-10) and tumor necrosis factor (TNF-alpha) before and after treatment.
RESULTSThe levels of IL-6, IL-10 and TNF-alpha in vitiligo patients were higher significantly than those in the normal group (P<0. 01, P<0. 05), the level of IL-2 was lower significantly than that in the normal group (P<0. 01) before treatment. After 3 sessions treatment, IL-2 level was increased significantly in the moxibustion group and the levels of IL-6, IL-10 and TNF-alpha were reduced, without significant differences as compared with the normal group (all P>0. 05). But the differences were significant as compared with those in the medication group (all P<0. 05). The curative and remarkably effective rate was 76. 3% (29/38) after treatment in the moxibustion group, which was higher significantly than 13. 3% (4/30, P<0. 05) in the medication group.
CONCLUSIONHeat-sensitive moxibustion achieves very good clinical efficacy on focal vitiligo, which is probably via promoting blood circulation and regulating the levels of IL-6, IL-10 and TNF-alpha.

This paper investigate the methods to detect engraftment rate of the four patients with hematological disorders who accepted nonmyeloablative allogeneic peripheral blood stem cell transplantation(NAPBSCT). To find out the best method, their engraftment rates were detected serially at different time after NAPBSCT by means of either FISH, or conventional chromosome analysis combined with R-banding analysis concurrently.The results were carefully compared with one another. All these four sex-mismatched cases were engrafted partially,and two of them changed to full engrafment. The results show no statistically significant difference in 3 groups (conventional method, FISH for hypermetaphase, FISH for interphase nuclei). But the results strongly indicate that FISH is a rapid, precise, objective,and reliable menthod for detection of the engraftment rate,and it is suitable for sex-mismatched NAPBSCT.
