The pleomorphic adenoma of epiglottis is rare. When the tumor grows larger, some patients may have symptoms of pharyngeal foreign body sensation, but other patients have no obvious symptom. The tumor is mainly found through indirect laryngoscopy or electronic laryngoscopy. This disease can be confirmed by pathological diagnosis after tumor resection.

Objective To establish the best extraction technology of Zhike oral liquid.Methods Using orthogonal experiment method, total flavonoids and baicalin as evaluation index, extraction time, solvent times, extraction times as factors, the optimal extraction process parameters were selected.Results The best extraction process of Zhike oral liquid:extraction time was 1h, solvent amount was 10 times, 2 times of extraction.Conclusion The extraction process is feasible, the test result is accurate and reliable, which can provide the experimental basis for the extraction process of Zheke oral liquid.

Purpose To discuss the value of MRI in the diagnosis of placenta implantation abnormality, and to explore preliminarily the relationship between MRI signs and types of placenta implantation abnormality. Materials and Methods The clinical preoperative data and postnatal pathological findings of 54 women at high risk of placenta accreta were collected. All the patients undertook the conventional pelvic MRI examination. The scanning sequences mainly included: sagittal, coronal and axial T2-weighted imaging-turbo spin echo, balance fast field echo. The MRI images were observed and the areas which showed low signal in all the three directions on T2WI were measured. Then the correlation between the areas of low signal on T2WI in placental and the types of placenta implantation abnormality was analyzed. Results The incidence of placenta implantation abnormality was 64.8% in our research (35/54). The main MRI signs were low signal on T2WI (68.5%, 37/54) and heterogeneous signal in placenta (57.4%, 31/54); the main sign of placenta percreta was tenting bladder (75.0%, 6/8). The types of placenta implantation abnormality were positively correlated with the areas of low signal on T2WI (r=0.454, P<0.05). Conclusion Pregnant women at risk of placenta accreta should be evaluated with imaging examinations, particularly with MRI scanning, to improve disease detection rate. The typical indirect signs of placenta implantation abnormality are low signal on T2WI and heterogeneous signal in placenta. The larger size of low signal area on T2WI in placenta, the deeper implantation of placenta.

OBJECTIVE: To explore the inhaled and food allergen distribution of patient with allergic rhinitis in north of Zhejiang and to analyze the difference of allergen distribution among different age groups. METHOD: One thousand and forty eight patients in north of Zhejiang diagnosed with allergic rhinitis in our outpatient department were tested with skin prick test (SPT). The positive rate of inhaled and food allergens were calculated. To analysis the difference of positive rate between children and adult. RESULT: Nine hundred and eighty-eight cases (94.3%) had the positive reaction. Dermato phagoides farinae and Dermatophagodies pteronyssinus had the highest positive ratio (72.1%, 71.8%) in inhalation group, followed cockroach (14.1%). In food group, Shrimp and peanuts had the highest positive ratio (18.3%,14.2%). Between children group and adults group, positive rate of food allergen was significantly different (P < 0.05), but of inhaled allergen was not significantly different. CONCLUSION The distribution of some allergens in children group and adults group was variable. The study shows that Dust mite was the mostly responsible common allergen in north of Zhejiang.

OBJECTIVE:To provide reference for rational drug use and strengthen the management of adjuvant medication man-agement in the hospital. METHODS:1 080 and 860 discharged medical records of 12 Vitamins for injection were selected from our hospital during Jun.-Nov. 2014 (pre-special comment group,i.e. group A) and Jun.-Nov. 2015 (post-special comment group,i.e. group B),respectively. The application of 12 Vitamins for injection,hospitalization stay,drug cost and the incidence of ADR were compared before and after adjuvant medication special comment. RESULTS:After adjuvant medication special comments,the propor-tion of drug use of no indication,unsuitable solvent selection,irrational drug dosage,drug use of drug interaction and contraindica-tion,drug cost and the incidence of ADR in group B were all lower than in group A,with statistical significance(P<0.05). There was no statistical significance in hospitalization stay between 2 groups(P>0.05). CONCLUSIONS:Clinical pharmacists adopt adju-vant medication special comments to effectively standardize clinical application of 12 Vitamins for injection in our hospital.

ObjectiveTo explore the possible mechanism of reducing cholecystitis and preventing cholelithiasis by Dahuang Lingxian Formula（大黄灵仙方， DLF）. MethodsFifty SD rats were randomly divided into blank group， model group， DLF group， DLF + blank inhibitor group， and DLF + inhibitor group， with 10 rats in each group. The rat model of cholecystitis was established by lipopolysaccharide （LPS） induction in all the groups except for the blank group. Rats in DLF group， DLF + blank inhibitor group and DLF + inhibitor group received intragastric administration of 320 mg/ （kg·d） of DLF 3 days before the preparation of cholecystitis model， while those in blank group and model group were given 2 ml/100 g of distilled water by gastric， twice a day， for 6 consecutive days. Hematoxylin-eosin （HE） staining was used to observe the histopathologic changes of bile duct tissues in each group. The expression of nuclear factor κB （NF-κB） protein in bile duct tissues was detected by immunohistochemistry. The expression levels of interleukin1β （IL-1β） and tumor necrosis factor α （TNF-α） in serum of rats were detected by enzym-linked immunosorbent assay （ELISA）. The mRNA expression levels of miRNA-30b， transforming growth factor β1 （TGF-β1）， nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） and bone morphogenetic protein 2 （BMP2） in bile duct tissues were detected by real-time PCR， and the protein expression levels of TGF-β1， NLRP3 and BMP2 were detected by Western blot. ResultsCompared to those in the blank group， the structure of the bile duct in the model group was abnormal， and a large number of lymphocytes， plasma cell infiltration and bile canaliculi dilation were seen in the portal area； the positive expression of NF-κB protein increased； there was nuclear infiltration； the expressions of serum inflammatory factors IL-1β and TNF-α， as well as the mRNA and protein expressions of TGF-β1， NLRP3 and BMP2 in bile duct tissue significantly increased， while the expression level of miRNA-30b significantly decreased （P＜0.01）. Compared to those in the model group， the pathological morphology of the bile ducts in the DLF group and DLF + blank inhibitor group was improved， and the infiltration of inflammatory cells was reduced， with decreased positive expression of NF-κB and nuclear infiltration； expression levels of serum inflammatory factors IL-1β and TNF-α， and the mRNA and protein expressions of TGF-β1， NLRP3 and BMP2 in bile duct tissue decreased， while the expression level of miRNA-30b significantly increased （P＜0.05 or P＜0.01）. Compared to the model group， those indicators in the DLF + inhibitor group was not significantly improved （P＞0.05）. There was no significant difference in the indicators between the DLF group and the DLF + blank inhibitor group （P＞0.05）. ConclusionDLF may play a role in delaying the progression of cholelithiasis by regulating the expression of miRNA-30b and inflammation-fibrosis related factors.
