OBJECTIVE To explore the expression of Bcl-2, on mRNA and protein levels, in the different age of C57BL/6 mice cochleae and the expression localization in the cochleae.METHODS Using ABR to test the hearing level in C57BL/6 mice. Surface preparation of cochlear basil membrane is used to observe the morphology and amout of the outer and inner hair cells in different age of C57BL/6 mice. Fluorescent quantitative real time PCR, immunofluorescence histochemical method and western blot are used to detect the expression of Bcl-2 on the mRNA and protein levels in the C57BL/6 mice cochlea of different age groups ('young group', 'elderly group').RESULTS ABR results showed that the hearing threshold of 'older' C57BL/6 mice is much higher than that in the 'young' mice, and surface preparation of cochlear basil membrane showed the hair cell localized in the cochlear basil turn of 'old' mice arranged in a disorder station and part of hair cells were lost. Also, the spiral ganglion cells arranged sparsely and messily. Fluorescence quantitative real-time PCR results suggest the expression of Bcl-2 on/at the mRNA level of the 'old' mice cochleae decreases significantly, compared to that in the 'young' mice. The results of Immunofluorescence and Western blot suggest the expression of Bcl-2 on/at the protein levels of the 'old' mice cochlea decreased, compared to that in the 'young' mice. Also, the Bcl-2 is located in the cytoplasm, and the expression of Bcl-2 in the inner hair cells seems higher than that in the outer hair cells. CONCLUSION The expression of Bcl-2 significantly deceased in the 'old' C57BL/6 mice cochleae, both on mRNA and protein level, which may be related to the hearing loss and loss of hair cells.

Objective To summarize the clinical nursing experience for patients with malignant obstructive jaundice after receiving percutaneous biliary radiofrequency ablation (RFA) and stent implantation. Methods The postoperative nursing experience in 9 patients with malignant obstructive jaundice who received percutaneous biliary RFA together with stent implantation were retrospectively analyzed. The postoperative complications and the nursing intervention measures were analyzed and evaluated. Results Biliary RFA and subsequent stent implantation were successfully carried out in all 9 patients. After the procedure, biliary fistula occurred in one patient, biliary hemorrhage in 2 patients and biliary infection in 2 patients. The patient, who developed biliary fistula, died one week later, and the clinical conditions in the remaining 4 patients were improved after symptomatic treatment. During the follow-up period of one month, the patients were in good condition. Conclusion The main purpose of postoperative nursing for patients after receiving percutaneous biliary RFA is to prevent the occurrence of bile duct perforation, hemorrhage, infection, etc. It is very important to keep the patients under close observation and comprehensive nursing so as to make an early detection and timely treatment of such complications, thus to reduce the incidence of complications causing serious consequences as well as to promote an early recovery.

ObjectiveTo observe the effect of topical sulfotanshinone sodium(STS) on sebaceous hyperplasia in animal models. MethodsThe sebaceous gland spots of adult male Syrian hamster flank organ served as the animal model. Sulfotanshinone sodium(0.5%) was applied to sebaceous gland spots in the right flank organ thrice daily, while those in the left were treated with normal saline as control. Parameters were examinedbefore, 10 days, 20 days and 30 days after the beginning of the topical treatment. A vernier caliper was utilized to measure the size of sebaceous gland spots, hematoxylin and eosin(HE) staining to observe the structure of sebaceous glands, immunohistochemistry to determine the expression of proliferating cell nuclear antigen (PCNA) in sebaceous gland cells, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay to assess the apoptosis of sebaceous gland cells. ResultsAt the baseline, no significant difference was observed in the size of sebaceous gland spots or in the proliferation and apoptosis of sebaceous gland cells between the two sides of flank organ(all P > 0.05), with tightly arranged intact sebaceous glands. Compared with normal saline, sulfotanshinone sodium significantly reduced the size of sebaceous gland spots(P < 0.05). Sebaceous glands were loosely arranged with decreased quantity and volume and obviously atrophic on day 30 in the right flank organ of hamsters. A decrease was observed in the expression of PCNA in sulfotanshinone sodium treated sebaceous gland cells compared with those treated with normal saline(P < 0.01 ), which was more striking on day 10 and 20(both P < 0.005). Sulfotanshinone sodium also induced an enhancement of apoptosis in sebaceous gland cells (P < 0.01 ), which was more apparent on day 20 (P < 0.005 ), and the degree of apoptosis was higher in the central area than in the peripheral area of sebaceous glands. ConclusionSulfotanshinone sodium can reduce the size and alter the microstructure of sebaceous gland spots, and inhibit the hyperplasia of sebaceous glands.

OBJECTIVE:To provide reference for drug consultation of Chinese patent medicine(CPM)in pregnancy. METH-ODS:Package inserts of CPM in our hospital during Jan.-Jun. 2016 were collected. Referring to the prohibited,contraindicated and caution materials and decoction pieces in Chinese Pharmacopoeia(part 1,2015 edition),based onnoteitem in Chinese Pharma-copoeia and Clinical Application Guidelines(2010 edition),problems existing in pregnancy contraindication labeling of package in-serts were compared and analyzed. RESULTS:There were 99 kinds of prohibited,contraindicated and caution materials and decoc-tion pieces in Chinese Pharmacopoeia. There were 210 package inserts of CPM except for the special medicine for children,in which 32 contained prohibited materials,61 contained caution materials,only 21 were in line with the contained materials. Among the package inserts of 93 CPM containing prohibited or caution materials,27 were included in Chinese Pharmacopoeia,13 in Clini-cal Application Guidelines only,17 in both,but only 6 had the same contraindication labeling. Among the package inserts of 32 CPM containing prohibited materials,6 were explicitly labeled prohibited,17 labeled contraindicated or caution,and 9 labeled none. Among the package inserts of 61 CPM containing caution materials,29 were labeled prohibited or contraindicated,15 la-beled caution,and 17 labeled none. Among the package inserts of 117 CPM containing no prohibited,contraindicated or caution materials,8 were labeled contraindicated in pregnancy,and 18 labeled prohibited in pregnancy. CONCLUSIONS:The pregnancy contraindications of most CPM are not normative,showing poor consistency with Chinese Pharmacopoeia or Clinical Application Guidelines. Except for providing drug consultation by complying with Chinese Pharmacopoeia,Clinical Application Guidelines and package insert,pharmacists can judge the CPM without labeled pregnancy contraindication by analyzing its classification of con-tained materials. Using TCM does not indicate safety drug use,in addition,some CPM contain western medicine ingredients. There-fore,pharmacists should conduct medication education for patients who used CPM in pregnancy. Considering the new and severe adverse reactions of TCM injections are more,its adverse reactions exist unpredictability,so that pregnant patients should be sug-gested to avoid using TCM injections by pharmacists.
