209 cases of allergic asthma were randomly divided into two groups, which received respectively traditional medicinal vesiculation and drug application based on syndrome differentiation, and their short - term and long - term therapeutic effects were investigated and compared, and the relation between the clinical therapeutic effects of the two application therapies and classification of TCM syndrome differentiation was further analysed. Results show that the total effective rate of the short -term of drug application based on syndrome differentiation is higher than that of medicinal vesiculation, and the clinical thertapeutic effect is closely related to classification of syndrome differentiation, the therapeutic effect of the short -term is the highest for lung -heat type and the worst for Yang-deficiency of kidney.

Objective:To explore the proliferation inhibition and radiosensitization of Biyanqing granule on nasopharyngeal carci -noma cell line CNE-2 in vitro.Methods:CNE-2 cells were cultured in vitro.The inhibition of Biyanqing granule on the proliferation of CNE-2 cell was evaluated by MTT assay .Radiosensitization was explored by clone formation assay , and cell cycle and apopotosis were observed by flow cytometry ( FCM) .Results:Biyanqing granule could inhibit the proliferation of CNE-2 in a time-and dose-dependent manner.The IC50 in 24, 48 and 72 h was 70.79, 60.13 and 51.63 mg· ml-1(calculated according to the weight of all medicinal ma-terial), respectively.The colony formation assay showed that Biyanqing granule combined with radiation could significantly reduce the colony formation of CNE-2 cells.With the concentration increase of the main drug , the colony formation of CNE-2 cells was reduced . The number of colony formation in the negative control group , the radiation group , 10 mg· ml-1 and 20 mg· ml-1 Biyanqing combined with radiation groups (calculated according to the weight of all medicinal material ) was significant different (P<0.05).With the main drug concentration increasing , the percentage of G 2/M phase and apoptotic cells were both increased , and compared with the con-trol group, the difference was significant (P<0.05).Conclusion:Biyanqing granule can not only inhibit CNE-2 cells but also block CNE-2 cells in G2/M to improve the radiosensitization of CNE-2 cells.

Objective To study correlation of the retinal nerve epithelium layer thickness measured with different optical coher-ence tomography (OCT) in vivo with histological measurement. Design Experimental study. Participants 15 rabbit eyes. Methods The retina measurement position of 15 rabbit eyes were marked by laser, and then were scanned by OSE-1800 OCT and Stratus OCT. Reti-nal nerve epithelium layer thickness was measured in retinal histological shdes of rabbit eyes. The results measured with three methods were compared and linear regression analyses were done with SPSS11.5 software. Results The average retinal nerve epithelium layer thickness measured with OSE-1800 OCT, Stratus OCT and histological method were 119.5±7.4, 118.0±5.6, and 116.3±8.8μm respec-tively(P=0.292). Retinal nerve epithelium layer thickness measured with both OCT instruments had the best correlation (r=0.914, P= 0.000), and the thickness measured with Stratus OCT and histological method had the better correlation (r=0.872, P=0.001), and the thickness measured with OSE-1800 OCT and histological method had the significant correlation (r=0.833, P=0.002). Conclusions The retinal nerve epithelium layer thickness measured with different OCTs in vivo correlate well with histomorphometry, and the measure-ment of both OCT instruments are accurate.

Objective To explore the application of mini-laparoscopy in the diagnosis and management of nonpalpable undescended testis in children.Methods 38 cases of impalpabal testes(46 testicular) had been operated by mini-laparoscopy in children with cryptorchidism.Results 38 children with nonpalpable undescended testis (46 testicular) had been operated by mini-laparoscope.Results After laparoscopic exploration,inguinal probe and postoperative pathology,it had been confirmed that 2 testicular were absent,34 testicular were found in high inguinal location,10 testicular were located in intraperitoneal cavity.In addition to the absent testicular,the rest had been performed with mini-laparoscope:one period descent fixation 41 testes,Fowler-Stephens (F-S) installment orchiopexy three testes.Follow-up with side testicular atrophy 2,including one period orchiopexy a testis,F-S installment fixation a testicular; Testicular rebound 1,who had been operated with one phase of testicular descent fixtion.Conclusion For inguinal failed to find the testicular,children with cryptorchidism should be done by laparoscopy because of its positioning accuracy,and most children can do a period drop fixed,but for those really intraperitoneal more exalted person,stage surgery should be needed.Its overall treatment effect is satisfactory and is worth popularizing.

Objective To study medial umbilical ligament in the prevention of recurrence of indirect inguinal hernia with large sac by laparoscopic treatment in children.Methods The clinical data of 178 cases of indirect inguihal hernia with large sacs in children were retrospectively analyzed.After high suture ligation of the internal ring with pediatric laparoscopy,all of the internal tings were covered with the same side of medial umbilical ligament to further strengthen.Results All cases were discharged from hospital 1～2 days after surgery.No recurrence and no any other complications could be found after following up 3～18 months.Conclusion Pediatric laparoscopic application of medial umbilical ligament to further cover the internal ring could significantly reduce the rate of recurrence for indirect inguinal hernia with large sac.This method of operation waft safe and feasible.It Was worth promoting.

AIM: To demonstrate the effects of telmisartan on the proliferation and apoptosis of U937 cells.METHODS: The proliferation ability of the U937 cells was assessed by CCK-8 assay and colony formation test with methylcellulose.The CD11b expression rate of the U937 cells was identified by flow cytometry.The apoptotic rate was analyzed by flow cytometry with Annexin V-PI double staining and Hoechst 33342 staining.The protein levels of cleaved PARP and cleaved caspase-3 were determined by Western blot.RESULTS: The results of CCK-8 assay confirmed that the viability of U937 cells was inhibited by telmisartan.The colony formation capacity of U937 cells was also significantly inhibited by telmisartan.The differentiation of U937 cells was induced by telmisartan with the expression of CD11b.The results of flow cytometry analysis with Annexin V-PI double staining and Hoechst 33342 staining identified that the apoptosis of U937 cells was induced by telmisartan in dose-dependent and time-dependent manners with the up-regulation of cleaved PARP and cleaved caspase-3 proteins.CONCLUSION: Telmisartan inhibits the proliferation and induces the differentiation of U937 cells.Telmisartan also induces the apoptosis of U937 cells through the caspase pathway.
