Objective: Through comparing the hospitalization costs of total knee replacement (TKR) in People’s Hospital of Peking University in 2005 and 2010, to investigate the changing status of hospitalization costs on this operation and the impact of clinical pathway ( CP ) on controlling the hospitalization costs during 5 years , and provide references for controlling medical treatment cost reasonably. Methods: The patients are grouped into undergoing unilateral and bilateral TKR. The total hospitalization cost and cost of each category during 5 years are compared, and SAS 9.2 statistic software is applied to deal the data. Results: Compared with 2005, the total cost for TKR in 2010 decreased. All the charging items decreased, except implant material increased, especially the cost of surgery, hospital room, nursing and pharmacy. Specific to one knee replacement group and both knees replacement, the changing trend of cost is coincident with the total cost. Conclusion: The total cost for TKR in 2010 was lower than that of 2005, which might be the result of adopting CP since 2010. Nevertheless, the implant material cost accounted large proportion of hospitalization cost in 2010, and it has obvious increasing trend compared to 2005. This result is related the increasing application of the new edition of Artificial knee joint prosthesis. Controlling implant material cost is the effective method of decreasing medical costs for TKR.

Objective:To observe the clinical efficacy of the combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium in the treatment of allergic rhinitis and its influence on inflammatory cytokines. Methods:Totally 94 cases of al-lergic rhinitis patients received treatment in our hospital were selected and divided into the observation group and the control group ran-domly. The control group received budesonide nasal spray and desloratadine citrate disodium, and the observation group received mon-telukast additionally. After 4-week treatment, the changes of clinical symptoms and the contents of IL-6, IL-8 and IL-10 in the two groups were compared. The clinical efficacy of the two groups was also compared. Results:After the treatment, the VAS score of the nasal symptom and category symptoms in the two groups were lower than that before the treatment, and the score of the observation group was lower than that of the control group (P<0. 05). After the treatment, the contents of IL-6 and IL-8 were significantly re-duced while the content of IL-10 was significantly increased in the two groups, and the changes in the observation group were more no-table than those in the control group (P<0. 05). The total effective rate of the observation group was 91. 49%, which was higher than that of the control group (80. 85%, P<0. 05). Conclusion:The combination of montelukast, budesonide nasal spray and deslorata-dine citrate disodium can significantly improve the clinical symptoms, reduce the IL-6 and IL-8 levels and increase the IL-10 content in allergic rhinitis patients.

Parkinson disease(PD)is a common,progressive and disabling neurodegenerative movement disorder. Diagnosis of PD depends on clinical history and physical examination,but misdi?agnosis is common in early stages because of similar symptoms to other movement disorders. which is why biomarkers are urgently needed to accurately diagnose PD,especially in the early stages of PD, and find new drug targets. This review discusses the curient research of the PD candidate biomarkers from cerebrospinal fluid and blood in terms of PD pathogenesis. We have found that dihy?droxyphenylacetic acid,alpha- synuclein and its related proteins in Lewy bodies,8- hydroxy deoxy?guanosine,uric acid,interleukin and neurotrophic factors are potential biomarkers. They participate in different stages of PD. In order to enhance the accuracy of early diagnosis and efficacy of drugs evalua?tion,we are to use multiple biomarkers rather than a single biomarker,in combination with different biologic pathways of biomarkers,neuroimaging as well as clinical symptoms.

OBJECTIVE: To observe the correlation between the threshold of tone burst auditory brain stem response (Tb-ABR) and ASSR (auditory steady-state response) and the threshold of BA (behavioral audiometry). To investigate the accuracy and clinical value of Tb-ABR and ASSR in pediatric hearing assessment. METHOD: From January, 2014 to December, 2014, 76 children (123 ears) recieved hearing examination in the First Affiliated Hospital of Zhengzhou University. They were classified into three groups according to the hearing level: 23 children (46 ears) with normal hearing ability in group A, 27 children (32 ears) with slightly-moderate sensorineural deafness in group B and 26 children (45 ears) with severe-profound sensorineural deafness in group C. Tb-ABR, ASSR, BA in 4 frequencies (0.5, 1.0, 2.0, 4.0 kHz) were tested and the results were statistically analyzed. RESULT: (1) At the 4 frequencies (0.5-4.0 kHz), we obtained 132 thresholds of Tb-ABR, 144 of ASSR, 152of BA. And 166 thresholds were obtained in Tb-ABR+ASSR+BA in total . (2) The thresholds of Tb-ABR, ASSR and those of BA in all 3 groups had linear relations at 0.5-4.0 kHz. The correlation coefficients of group A were 0.76, 0.82, 0.87 and 0.91; 0.52, 0.57, 0.67 and 0.64. Those of Group B were 0.89, 0.95, 0.98 and 0.95; 0.74, 0.82, 0.87 and 0.90. Those of Group C were 0.91, 0.90, 0.92 and 0.89; 0.93, 0.95, 0.95 and 0.91. CONCLUSION (1) Both ASSR and Tb-ABR can allow reasonably accurate predictions for the pediatric hearing assessment. The correlation between Tb-ABR threshold and BA threshold is higher in normal hearing children and slightly-moderate sensorineural deafness children. The correlation between ASSR threshold and BA threshold is higher in severe-profound sensorineural deafness children. (2) The hearing test combination can evaluate the residual hearing ability for children with severe hearing loss.

Objective To investigate the correlations between the time of thoracic endovascular aortic repair (TEVAR) and prognosis in patients with type B acute aortic dissection (AADB). Methods The clinical data of 156 AADB patients with TEVAR was retrospectively analyzed and divided into 3 groups according to the time from onset of symptom to TEVAR:less than seven days was deifned as group 1 (G1, n=87), seven days to fourteen days group 2 (G2, n=48);more than fourteen days was group 3 (G3, n=21). The status of aortic reconstruction at three months TEVAR, in-hospital mortalities, mean hospital expense and length of stay were compared among three groups. Results Before TEVAR, there was no signiifcant differences in the ratio of smallest true lumen diameter and largest false lumen diameter amony the three groups (0.47±0.33, 0.42±0.18, 0.47±0.27, respectively, P>0.05). At three months after TEVAR, the ratio of largest true lumen diameter and largest false lumen diameter among the three groups was signiifcantly greater in group 1 (1.76±0.51) than group 2(1.42±0.30) and group 3(1.34±0.34, P < 0.05), when there was no signiifcant difference between the later two groups. Complete aortic reconstruction (8 from group 1 and 4 from group 2) was achieved in 12 patients at 3 months after TAVAR. Eight patients died during hospitalization, 5 from visceral ischemic, 2 from proximal aortic dissection, one patient from sudden death. Compared with G3, the hospital expense of group 1 and group 2 was cut down about ￥20000. Length of stay was signiifcant greater in group 3 than in group 1 and group 2 (P<0.05). Conclusions Early TEVAR for AADB was safe and beneifcial for aortic reconstruct and reducing the hospital expense and length of stay.

Objective: To observe the effects of carotenoids extracts from Potamogoton crispus L. (CEPC) on proliferation and apoptosis of Hela cell line. Method: The cell growth inhibition was tested in MTT assay and cell cycle arrest was measured by flow cytometry (FCM). Apoptotic cells were observed by fluorescent microscope and Laser scanning confocal microscopy (LSCM). LSCM was also used to determine the Ca2+ concentration in cells. Results: CEPC had strong inhibition effects on the cell growth. The cell cycle progression was arrested at G2/M phase. The typical characteristics of apoptotic cells such as chromatin condensation were observed by the fluorescent microscope and LSCM. The concentration of intracellular Ca2+ was remarkably increased after treatment of CEPC as compared with the control. Conclusion: Apoptosis of Hela cell line is the important anticancer mechanism of CEPC and the increase of intracellular Ca2+ level might participate in the process.
