Objective To investigate the possible association of mtDNA deletion in spiral ganglion of cochlear and cochlear nucleus of brain in young and elder rat with presbyacusis.Methods The mtDNA 4834 deletion in spiral ganglion of cochlear and cochlear nucleus of brain in rat was analyed by PCR.Results The deletion rate of mtDNA 4834 in rat with presbyacusis was 66.7% in spiral ganglion, 100% in cochlear nucleus of brain.While no deletion was detected in young rat.Conclusion Deletion in mtDNA of the spiral ganglion of cochlear and cochlear nucleus of brain was found in rat with presbyacusis, and it may play an important role in the pathogens of presbyacusis.

13th Five-Year period is China's comprehensive completion of the decisive stage of a well-off society,when the development of public hospitals is facing great opportunities and challenges.Five development concepts introduced by the fifth Plenary Session of the 18th CPC Central Committee,offer guidance on public hospital reform and development.Among such concepts,innovation is leading the first power of hospital development;Coordination is the inherent requirements of the hospital' s sustainable and healthy development;Green is a necessary condition for the sustainable development of the hospital,and also an important reflection of the hospital development achievement;Opening is the only way for the rapid development of hospital;Sharing is the essential requirement of hospital development.Five development concepts shall guide the reform and development of Chinese public hospitals during the period of 13th Five-Year.

Eighty-three patients with transient ischemic attack (TIA) were randomly divided into study group (n =42) and control group (n =41) from July,2011 to Mar,2015.Patients in both groups were given aspirin 100 mg/d ; in addition,patients in study group received intravenous infusion of argatroban 10 mg,q12h,for 7 days and those in control group received subcutaneous injection of low molecular weight heparin (LMWH) 2 050 AXa IU,b.i.d for 7 days.The cases with cure,significantly effectiveness and effectiveness in study group and control group were 10,14,16 and 6,12 16,respectively.Compared with the control group,argatroban shows superiority in treatment of TIA with higher safety and lower side effect.

Micro Network interactive system introduced the whole process of medical morphology laboratory which creates a new teaching mode and significantly improve the teaching quality and efficiency for medical Morphology Experimental teaching, by full realization of a clear vivid images, language interaction and the sharing of information resources and diluting the discipline lines. At the same time, It put forward new demands about knowledge and ability of network knowledge, techniques, image data sources, the development and application of function to teachers.

Objective To optimize the extraction method for assaying Jinyou Tankeqing Tablets(JTT).Methods With the total flavonoids content as the index,Orthogonal Experimental Design was used to optimize the extraction condition for assaying JTT.Results The optimized ultrasonic extraction method was as follows: adding 0.2 mL?mg-1 powder to 95 % ethanol,extracting for 30 min;the optimized Sohlex extraction method was: adding 1.2 mL?mg-1 powder to 95 % ethanol,extracting for 2 h,the former method being better than the later.Conclusion The optimized extraction method for assaying JTT is adding 0.2 mL?mg-1 powder to 95 % ethanol and extracting for 30 min with ultrasonic wave.

PurposeTo establish sensitive and reliable serum marker on liver fibrosis for early clinical diagnosis. MethodsSerum hyaluronate acid,type Ⅲ procollagen and type Ⅳ procogen of 48 patients with viral hepatitis were analyzed by radioimmunoassay and ELISA respectively. ResultsThe serum HA, PCⅢ and PCⅣ level increased gradually with the progress of the disease. Their levels were correlated distinctly with the index of hepatic activity of inflammation and that of fibrosis.ConclusionsThe value of serum HA,PCⅢ and PCⅣ in predicting liver fibrosis will be enhanced ff the effect of inflammation could be excluded.

Objective To study the quality standard of Jinyou Tankeqing Tablets (JTT). Methods Total flavonoids in JTT were identified by TLC. Naringin content in JTT was determined by HPLC. Results The relevant spots of total flavonoids in JTT can be identified by TLC. The content of naringin in JTT can be determined by HPLC. The linearity of naringin was good in the range of 2～20 ?g (r= 0.999 9). The average recovery of naringin was 101.29 %with RSD = 2.58 %. Conclusion The established quality standard is simple,feasible and repeatable,and can be used for the quality supervisory of JTT.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efficacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted.

Objective In this research,the relationship between blood estrogen level and salivary glands of female rat was studied.Methods Thirty-two female Wister rats were randomly divided into four groups:control group,sham operation group,ovariectomized and injected estradiol benzoate group and ovariectomized group.Menopausal rat model was established by ovariectomy.By testing E2,histological examination and examing Cu,Zn-SOD expression through immunochemical staining,we studied the effects of estrogen decreasing on female rat salivary.Results Compared with control group,sham operation group,ovariectomized and injected estradiol benzoate group,a significant decrease in scrum estrogen level was observed in ovariectomized group(P

This paper, on top of its introduction of the concept of medical ethics counseling, analyzed the necessity of establishing a medical ethics consultation system in China.By reviewing the development of the medical ethics counseling system in other countries, the authors, in view of China′s medical practice, put forward specific recommendations on establishing a medical ethics counseling system in China.Issues on the construction of organ donation ethics counseling system in China were also discussed in focus.
