The intraspecies quorum sensing system of Streptococcus mutans is involved with com genes family.ComE is a kind of response regulator and act as a promoter to the quorum sensing genes.S.mutans comE mutant strain IFD140?comE was constructed using the inframe-deletion system via twice homologous recombination.In current genetic studies of S.mutans,insertion duplication and allelic exchange mutagenesis techniques routinely create polar effects to downstream genes.In-frame deletions are essentially free of these polar effects because the mutation does not introduce any genetic markers.By PCR,sequencing and RT-PCR,it was confirmed that IFD140?comE has only 717bp deleted within the comE gene and the transcription of the downstream gene comD was not interfered.The research of the morphological characteristics indicated that IFD140?comE formed clumps and cells accumulated at the bottom of the glass tubes and light-microscopic observations displayed that the mutant strain formed significantly longer chains compared to those formed by the wild strain.The successfully construction of IFD140?comE lay a foundation for further quorum sensing research.

Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

Objective To study the efficiency of using autogenous temporalis fascia which was formed and shaped by formaldehyde cross-linking with special fasciaform molds in the repair of large tympanic membrane perforations. Methods Base on machine technique and published data, the molds was designed according to the shape of tympanic membrane (TM), autologous fascia graft shaped by 4% formaldehyde (pH 5.6) was cross-linked on the mold to resemble the natural TM more closely repairing the large perforations of tympanic membrane with the formed fascia. Sixty-one operations were performed to close large perforations in patients with intact ossicular chain in fifty-seven patients from November 2006 to April 2009. The follow up was done from one month to thirty months; the average follow up period was eleven months. Statistical analysis was performed usig a SPSS 13.0 software. Results The repairing of the perforations were successfully with rate of 95. 1% (58/61 ). Three ears were remained small remnant perforations after the surgery, but all hearing had been improved except one patient with biauricular total sensorineural hearing loss within the group. The air bone gap (ABG) of preoperative average (x ± s) hearing level of fifty-nine ears was (31.5 ±6. l)dB, and the ABG of postoperative average hearing level of same group was (14.2 ±4. 4) dB, the diference was significant ((=21.3, P <0. 01 ). During the early stage of using this technique, six ears were found to have graft lateralization recovery, but one case was slightly blunting recovery. No pearl tumor and epicyst had been found during the follow-up period. Conclusions The formaldehyde fasciaform technique produces consistent, reliable as well as reproducible results for repairing large tympanic membrane perforations with minimal complications.
