Objective To investigate the correlation of clinicopathological features with osteopontin and aquaporin-1 expres-sion in laryngeal carcinoma.Methods From August 2011 to December 2014 in Dongfeng General Hospital,80 laryngeal cancer specimens and adjacent normal tissue samples were selected,all samples were carried out osteopontin and aquaporin Immunohistochemical analysis expression and clinicopathological characteristics and correlation analysis.Results Osteopon-tin staining particles and aquaporin-1 were located in the stromal cells,yellow dye.In cancer tissue,osteopontin and aquapor-in-1 positive granules were mainly located in the cytoplasm of cancer cells,diffuse shading,coloring deeper place near nests. The positive expression rates of osteopontin and aquaporin-1 in the laryngeal carcinoma were 70.0% and 56.3% respective-ly,the positive rates in the adjacent tissues were 5.0% and 7.5% respectively that compared to the differences were statisti-cally significant (P <0.05).In 80 cases of laryngeal carcinoma.The expression of osteopontin and aquaporin-1 in different clinical stages,differentiation and lymph node metastasis tissues were statistically significant (P <0.05).Spearman correla-tion analysis showed that the osteopontin and aquaporin-1 in laryngeal carcinoma were positively correlated (P <0.05).Con-clusion Osteopontin and aquaporin-1 expression in laryngeal carcinoma were showed high status,and the clinical stage,de-gree of differentiation and lymph node metastasis were significantly correlated that can work together to promote tumor inva-sion and metastasis.

[ABSTRACT]OBJECTIVETo investigate the therapeutic effect of early combination treatment with intratympanic glucocorticoid injection for sudden sensorineural hearing loss(SSNHL).METHODSTotal of 178 patients with diagnosis of SSNHL, including 44 with hearing loss at middle-low frequencies,50 at high frequencies,44 at all frequencies and 40 at total deafness, were randomly divided into combination treatment group (CT group) and systemic oral prednisone group (OP group).CT group (82 patients) received intratympanic administration of methylprednisolone and oral prednisone in tapering doses. Pure-tone threshold audiometry (PTA) was performed at week 8 after beginning of therapy. RESULTSIn middle-low frequencies, the final PTA and PTA improvement were 26.14±24.82 dB and 42.23±1.61 dB in CT group respectively, and were 37.91±13.98 dB and 30.00±13.30 dB in OP group respectively (both P<0.05). In high frequencies, all frequencies and total deafness SSNHL group, the differences of the final PTA and PTA improvement were not statistically significant in both groups. The PTA improvement in CT group for total deafness (26.52±14.03) dB was more than that of OP group (22.06±11.17)dB (t=2.361,P<0.05). In middle-low frequencies, the recovery rate was 72.73%(16 cases) in CT group, and 40.91% (9 cases) in OP group, the difference was significant (χ2=4.539,P<0.05), but not in apparent effective rate, effective rate and total effective rate. In high frequencies, all frequencies and total deafness, there were no significant differences in therapeutic effect. The recovery rate of total CT group (40.24%) was significantly increased compared with that of OP group (26.04%)(χ2=4.061,P<0.05), the differences of apparent effective rate, effective rate and total effective rate were not statistically significant in both groups.CONCLUSIONFor low-middle frequencies SSNHL, the early combination treatment with intratympanic glucocorticoid injection leads to higher hearing recovery and therapeutic effect compared with traditional oral prednisone. Systemic application should be applied for high frequencies, all frequencies and total deafness of SSNHL.

This article was aimed to study the chemical constituents of the petroleum ether fraction of Liparis nervosa.Chemicalcompoundswereisolatedandpurifiedthroughvariouschromatographytechniques.The accurate structures of chemical compounds were confirmed with spectral data and literatures. The results showed that7chemicalconstituentswereisolatedfromthepetroleumetherfractionofLiparis nervosa,whichwere moscatin (1), batatasin Ⅲ (2), bergapten (3), isoimpinellin (4), xanthotoxin (5), imperatorin (6) and β-sitosterol (7). It was concluded that chemical constituents 3-7 were isolated from this genus for the first time. And chemical constituents 1-7 were isolated from this plant for the first time.

Objective: To investigate risk factors and epidemiological characteristics of bacillary dysentery outbreaks in three schools, and to provide scientific basis for the prevention and control of the epidemic in the future. Methods: Case definition was established. All suspected, possible and confirmed cases of all students and faculty members from 3 schools (A, B, C) were selected for epidemiological investigation. Control group was used for case-control analysis, and relevant samples were collected for laboratory testing. Results: A total of 132 cases were found in 3 schools, all of which were from students, with the incidence rate of 17.74%. The morbidity in kindergarten A was 20.00%, in center primary school B it was 21.74%, and in junior middle school C it was 11.61%. Cohort studies and casecontrol studies suggested that schools are exposed places and that washing hands with raw water in schools was possible risk factor [OR(95%CI) =4.50(1.01-20.11)]. Nine stool samples were tested in laboratory, among which 8 were positive for Shigella(88.99%), and Shigella was detected in the end nodes of school s pipeline network, the water samples from canteen bucket, and the floor drains of sewer pipe. Conclusion The bacillary dysentery outbreaks in 3 schools was caused by Shigella, which may be due to fecal contamination of domestic water in 3 schools before the start of the school year. It is suggested to strengthen the management of centralized water supply and construction in rural areas, intensify the supervision at all levels, and sanitation and disinfection before school opens at all levels.

Objective To explore the needs of community pharmacy services in elderly hypertensive patients in the community, especially empty-nest elderly patients. Methods Elderly hypertensive patients living in Ouyang street were randomly selected and divided into empty-nest and non-empty-nest groups by cluster random sampling method. The basic information of the respondents, the frequency of hypertension monitoring, the taking of hypertensive drugs, and the taking of other drugs were compared and analyzed. Results In term of “blood pressure monitoring frequency”, the daily pressure measurement of the empty-nest group and the non-empty-nest group accounted for 33.6% and 19.3%, respectively. There was significant difference between the two groups (P<0.05).In term of “the varieties of hypertension drugs” and taking 3 kinds of hypertension drugs at the same times, the empty-nest group accounted for 28.8% and the non-empty-nest group accounted for 16.7%, and the difference between the two groups was significant (P<0.05)；In term of “the varieties of drugs” and taking 1-2 kinds of Chinese patent drugs at the same time, the empty-nest group accounted for 39.6% and the non-empty-nest group accounted for 26.0% , and the difference between the two groups was significant (P<0.05)。Conclusion Community elderly patients with hypertension, especially empty-nest elderly patients have an urgent need for community pharmacy services，Community pharmacy services personnel should provide personalized and targeted medication education and guidance to elderly patients, especially empty-nest elderly patients, to promote the rational drug use in elderly patients.
