OBJECTIVE:
To construct a kind of recombinant plasmid PGCsi-AQP1 delivery with DOPC and explore the inhibit effect of laryngeal carcinoma by RNAi targeting AQP1 in vivo.
METHOD:
Male BALB/c mice, 6 weeks of age transplanted with laryngeal carcinoma cell line Hep-2, four groups were divided randomly: Tail vein injection group (TVIG), Carcinoma around injection group (CAIG), negative control group (NCG) and blank control group (BCG). The recombinant plasmid PGCsi-AQP1 delivery with DOPC were inject into tail vein or surrounding tumor. HE pathological slides and tumor size were observed and inhibitory rate was figured up. The level of AQP1 protein expression and high microvessel density were detected by Immunohistochemical staining (IHC).
RESULT:
We constructed BALB/c mice models of laryngeal carcinoma successfully (1) HE staining: cell putrescence, nuclear pyknosis and apoptotic bodies were more in the tumor tissues of experimental groups than two control groups. (2) The total volumes of tumor in experimental group were both smaller than in two control groups (P < 0.01). The inhibition rate of TVIG and CAIG were 52.4% and 53.5% respectively and there was no significant difference (P > 0.05). (3) IHC: the AQP1 positive cells and microvessel density in TVIG and CAIG were both less than in two control groups (P < 0.01).
CONCLUSION
Neutral lipsomes DOPC could help carriaging the recombinant plasmid PGCsi-AQP1 to tumor and then play an inhibit role in laryngeal carcinoma tissue by RNAi targeting AQP1 in vivo.

OBJECTIVE:
To report a case of follicular dendritic cell sarcoma (FDCS) of tonsil,analyze its clinical and pathological features, as well as the diagnosis and differential diagnosis.
METHOD:
Tonsillectomy of low temperature coblation were done with general anesthesia. Histopathology, immunohistochemistry, electron microscope were used to analyzed the features of FDCS. The clinical character and treatment were reported.
RESULT:
There was no evidence of recurrence in two years.
CONCLUSION
A correct diagnosis of FDCS was difficult to make , and immunohistochemical and ultrastructural studies are useful to FDCS's diagnosis. Low temperature coblation used in FDCS need more experience.

Allergic rhinitis (AR) is a nasal inflammatory,IgE-mediated disease that occurs when some individuals inhales something he or she is allergic to,such as pollen or animal dander.It is also a refractory disease with high prevalence in the field of rhinology.The treatment of AR is really a difficult and challenging task because of the high prevalence,economic burden and the interference to the quality of life.At present,nasal corticosteroid and antihistamines were the mainly therapies,however,there is up to 40% patients not satisfactory to these therapies.So exploring new therapy or target is necessary.This article will review the results of previous studies focused on the new therapies of AR.

Objective To investigate the role of lymph vessel density (LVD) and microvessel pericyte coverage index (MPI) in the pathogenesis of nasal polyps.Methods Using immunohistochemistry and immunofluorescence double staining method,the expressions of albumin,D2-40 and CD34-α-SMA in 11 specimens of normal nasal mucosa,26 specimens of nasal polyp and 26 specimens of inferior turbinate tissue from patients with nasal polyps were investigated.The counts of microvessel density (MVD),lymph vessel density (LVD) and microvessel pericyte coverage index (MPI) were compared.SPSS 17.0 software was used to analyze the data.Results The nasal polyp group(0.269 ±0.096) had more albumin than inferior turbinate tissue group (0.159 ± 0.078) and normal nasal mucosa group (0.138 ± 0.045),the differences were significant (q value was 4.873,4.446,both P < 0.05).The counts of MVD in nasal polyp group (30.52 ± 4.42) were not significantly higher than those in inferior turbinate tissue group (30.33 ± 6.03) and normal nasal mucosa group(28.21 ±6.84),the differences were not significant (q value was 0.130,1.147,both P >0.05).The MPI in nasal polyp group (0.291 ±0.096) was significantly lower than those in inferior turbinate tissue group(0.432 ± 0.101) and normal nasal mucosa group(0.416 ± 0.071),the difference was significant (q value was 5.399,3.680,both P < 0.05).The counts of LVD in the nasal polyp group (0.245 ± 0.073) were significantly lower than those in inferior turbinate tissue group (0.431 ± 0.054) and normal nasal mucosa group (0.470 ± 0.078),the difference was significant (q value was 10.004,9.328,both P < 0.05).MPI expression in the nasal polyp group was negetively correlated to albumin expression(r =-0.889,P < 0.05).The LVD expression in the nasal polyp group was negetively correlated to albumin expression(r =-0.901,P < 0.05).Conclusion Different LVD and MIP in nasal polyp tissues and normal nasal mucosa tissues imply that microcirculatory dysfunction plays a crucial role in the pathogenesis of nasal polyps.

Complementary and alternative medicine (CAM) describes a broad category of practices and treatments for the prevention or treatment of disease outside the realm of conventional medicine. CAM is widely used in the treatment of allergic rhinitis, acute and chronic rhinosinusitis. This article summarizes a variety of CAM and the efficacy in the treatment of rhinitis and sinusitis, with the purpose of increasing people′s awareness of CAM and enriching the treatment of rhinitis and sinusitis, so that patients can benefit from it.
