Objective To investigate the phenotype, frequency of Th17 cells and the association between Th17 cells and viral clearance in patients with H1N1 influenza A. Methods Three groups including 70 confirmed patients with H1N1 influenza A, 30 patients with seasonal influenza as well as 68 healthy subjects as controls were enrolled in this study. The percentages of Th1, Th2, Treg and Th17 lymphocytes in the peripheral blood were determined by intracellular staining and flow cytometry. The levels of interferon-γ (IFN-γ), transforming growth factor-beta (TGF-β),interleukin-6 (IL-6) in plasma and supernatant of the peripheral blood mononuclear cell (PBMC)culture were quantified by enzyme-linked immunosorbent assay (ELISA). Viral load in nasopharyngeal swabs was detected by real time quantitative reverse transcription-polymerase chain reaction (RTPCR). Data were analyzed by one way ANOVA and liner correlation analysis. Results The percentage of Th17 cells in H1N1 influenza A patients was (2. 740±0. 210)%, which the percentage of was significantly decreased compared to healthy subjects (3. 443 ±0. 154)% and seasonal influenza patients (3. 443±0. 277) % (F=4. 242, P<0. 05); while the percentage of Thl, Th2 and Treg cells were not significantly different among these groups. Moreover, the TGF-β level in plasma of H1N1 influenza A patients was (10±8) ng/mL, which was significantly lower than healthy subjects (43 ±32 ) ng/mL and seasonal influenza patient ( 18 ± 10) ng/mL ( F= 17.72, P<0.01 ). The TGF-β level in the supernatant of PBMC culture of H1N1 influenza A patients was (782 ± 736) pg/mL, which was significantly lower than healthy subjects (1462±315) pg/mL and seasonal influenza patients (1481 ±348) pg/mL (F=5. 730, P<0.01). Additionally, the viral clearance period was inversely correlated with the percentage of Th17 cells (r=-0.38, P=0.02). Conclusions The proportion of Th17 cells in patients with H1N1 influenza A is significantly decreased, which is closely correlated with the level of TGF-β. This decrease may results in the delayed viral clearance.

Objective To compare the effect of treating cricopharyngeal achalasia in stroke survivors using transnasal or transoral balloon dilatation.Methods Thirty stroke survivors with cricopharyngeal achalasia were randomly divided into a transnasal and a transoral balloon dilatation group (group N and group O),each of 15.Both groups were given routine swallowing rehabilitation training as well as the transnasal or transoral balloon dilatation.Their heart rate was monitored during the dilatation.Nasal bleeding,mucous membrane swelling and pain were also observed.Their swallowing function was evaluated using the Fujishima Ichiro swallowing efficacy score (FISE) and videofluoroscopy (VFSS) before and after the intervention.Results After the treatment,the average FISE and VFSS scores of both groups had improved significantly comnpared to before the treatment but there were no significant differences between the groups.During the treatment,the average heart rate of group O increased significantly less than that of group N.The treatment acceptance of group O was 98.2%,significantly higher than that of group N (80.1%).One case of mucosal bleeding was observed in group O,and laryngeal edema occurred significantly less often than in group N (9 cases vs.7).The average pain score was also significantly lower in group O.Conclusions Balloon dilatation facilitates swallowing among stroke survivors with cricopharyngeal achalasia.The transoral approach can help to reduce the occurrence of complications such as mucosal bleeding,laryngeal edema and pain,and has better patient acceptance.

Objective: To investigate the effect and the mechanism of Astragalus membranaceus (Huangqi in Chinese, HQ) extract on the intestinal absorption of six alkaloids of Aconitum carmichaelii (Fuzi in Chinese, FZ) in rats with spleen deficiency and provide novel insights into the application of HQ on modulating intestinal barrier. Methods: Four-week-old male Sprague-Dawley rats were fed with Xiaochengqi Decoction to induce the spleen deficiency model for 40 d. Single-pass intestinal perfusion model were used to study the effects of HQ extract on the absorption of alkaloids. Protein expression and mRNA levels of MRP2 and BCRP and tight junction proteins (TJ, including Claudin-1, Occludin and ZO-1) were measured using Western blot and real-time PCR, respectively. The location and expression of TJ protein was also investigated by the immunofluorescence method. Results: Compared with the normal group, the protein expression of MRP2, BCRP and TJ proteins in the model group were significantly down-regulated. After oral administration of HQ, the alkaloid absorption in intestinal villi was inhibited, MRP2, BCRP and TJ proteins were up-regulated, the green fluorescence staining of Claudin-1, Occludin, and ZO-1 was enhanced, and a thick layer of mucus was deposited on the surface of the epithelium of the intestinal cavity. Conclusion: HQ as an intestinal barrier modulator improves the physiological changes of the intestinal environment of spleen deficiency to reduce the absorption of toxic components, leading to a decrease in the absorption of drug-like molecules.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance, Innovation, and Development of traditional Chinese medicine(TCM) and the spirit of the National Conference on TCM, Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis (AR) and they reached a basic consensus. In recent years, the prevalence of AR has been on the rise, threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity, and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease, western medicine features rapid onset. However, it is cost-intensive and causes severe surgical trauma, and the recurrence is common. TCM boasts diverse methods for AR, which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion, runny nose, or dysosmia in the attack stage, preventing recurrence in the remission stage, and treating refractory AR or steroid-resistant AR. In particular, acupuncture enjoys a reputation in treatment of AR, which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR, TCM regulates the psychosomatic conditions, which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine, give full play to the unique nonnegligible and irreplaceable advantages of TCM, formulate a comprehensive diagnosis and treatment scheme for learning and promotion, and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.
