Neutrophil genatinase-association lipocalin(NGAL)is a kind of lipocalin of binding proteins that seems to be a popular topic studied much recently,which at first was considered as endogenous bacteriostatic agent.It is bound up with the occurrence,development and prognosis of many kidney diseases.Therefore,it can provide new idea and method on clinical diagnosis and treatment by further study on expression and significance of NGAL in kidney diseases.

Objective To evaluate the academic level and the popularity of Chinese Journal of Orthopaedics from the point view of citation. Methods According to the information of Chinese Medical Citation Index (CMCI), the amount and distribution of the original articles in Chinese Journal of Orthopaedics cited by the journals included by CMCI were statistically analyzed. The data analysis included the percentage of cited articles, the number of citation of a single article, authors of most cited articles, geological regions of cited articles, citing journals, the self citing rate and years of citation. Results The percentage of cited papers (663 articles, 3728 times) in all published 1 182 articles in Chinese Journal of Orthopaedics from 2005 to 2009 was an average of 56.09%. The average time of original articles cited by other researchers was 5.62. The highest one was citated by 104 times. 210 articles (31.68% of total papers) were cited 5 or more times, and the all cited times from them were 2835 (76.04% of total cited times). 663 cited articles were written by 485 authors from different countries. The most frequently cited author wrote 12 papers. The number of authors with one paper cited was 386 (79.58% of total authors). The cited authors are from the mainland, HongKong, and Taiwan in China, as well as USA, Canada, France. Beijing, Shanghai and Tianjin are leading cities in orthopaedic research. Beijing was the first place (32.16% of total authors). There were 445 citing journals. There was 217 items self cited; the self- citing rate is 0.058. Conclusion Chinese Journal of Orthopaedics has provided high quality articles and has a strong influence in the field of medical research. It has been become an important resource for orthopaedic researchers and a vital medical journal in China.

OBJECTIVE:To provide references for improving the governmental drug pricing,especially for brand-name drugs.METHODS:With the statistical data listed in the governmental drug price catalogs,the price difference rates between brand-name and generic injection were computed.RESULTS:Only 26%of the drugs were in line with the requirement on price difference rate(35%for injections)specified in governmental drug price principle,and the highest price gap between brand-name drug and generic drug was as high as over 500%.CONCLUSIONS:It is advisable for government to adopt mild method of gradual reduction of drug prices,control the preferential degree for the price of the brand- name drugs,establish a dynamic price control system,and promote the balance on the benefits of both brand-name drug manufactures and the generic drug manufacturers.

Objective: To study the in vitro effects of propofol on apoptosis and Bax expression induced by TNF-α in mouse spinal cord neurons. Methods: Spinal cord neurons were isolated from fetal mice and cultured in neurobasal medium with B27 supplement. On the 7th day of culture, neurons were randomly divided into 6 groups: control group, propofol (50 μmol/L) group, TNF-α group, propofol(25 μmol/L) with TNF-α group, propofol(50 μmol/L) with TNF-α group and propofol(100 μmol/L) with TNF-α group. Propofol with different concentrations was incubated with cultured cells for 30 min, then TNF-α was added with the final concentration of 2 000 U/ml for another 24 h incubation. Apoptosis was detected by PI/Hoechst33342 double staining technique and fluorescence microscopy. Bax expression was determined by immunocytochemical technique. Results: The apoptosis rate and expression of Bax in TNF-α group were both increased compared with those in control group ([21.8±1.1]% vs [2.8±0.8]%,P<0.01; [0.251±0.016] vs [0.141±0.015],P<0.01). The apoptosis rates and expression of Bax in 3 propofol groups(25, 50, 100 μmol/L) were ([16.2±1.2]%, [15.3±0.6]% and [12.2±0.8]%) and ([0.198±0.011],[0.188±0.012] and [0.167±0.014]), respectively, and they were all significantly decreased compared with those in TNF-α group ([21.8±1.1]% and [0.251±0.0163], all P<0.05). Moreover, a dose-dependent manner was observed in the above changes. Conclusion: Propofol within clinical concentration ranges may inhibit the apoptosis of spinal cord neurons induced by TNF-α through modulating the expression of Bax.

Objective To observe the clinical therapeutic effect of acupuncture combined with acupoint injection in the treatment of post -stroke intractable hiccup.Methods 120 patients with post -stroke intractable hiccup were randomly divided into treatment group(60 cases)and control groups(60 cases)according to the digital table.The patients in the control group were treated with baclofen tablets and methloxetamine hydrochloride injection, and the patients in the treatment group were treated with acupuncture combined with acupoint injection therapy.The treating period was 1 week.The scores of hiccup symptoms,the total effective rate and side effect were recorded before and after the treatment in all patients.Results The scores of hiccup symptoms before treatment in the treatment group and the control group were (5.32 ±1.17)points and (5.25 ±0.65)points respectively,there was no statistically significant difference between the two groups(t =1.79,P =0.96).The scores of hiccup symptoms on the 1 day after treatment in the treatment group and the control group were (3.97 ±1.24)points and (3.85 ±1.02 )points respectively,there was no statistically significant difference between the two groups(t =1.93,P =0.48).The scores of hiccup symptoms on the 3 days after treatment in the treatment group and the control group were (2.80 ±0.73)points and (3.75 ±1.11)points respectively,there was significant difference between the two groups(t =2.66,P =0.00), that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 5 days after treatment in the treatment group and the control group were (2.25 ±1.07)points and (3.43 ±0.81)points respec-tively,there was significant difference between the two groups(t =2.85,P =0.00),that in the treatment group was lower than the control group.The scores of hiccup symptoms on the 7 days after treatment in the treatment group and the control group were (1.27 ±0.66)points and (2.02 ±0.98)points respectively,there was significant difference between the two groups(t =1.07,P =0.00),that in the treatment group was lower than the control group.The total effective rates in the treatment group and the control group were 90%(54 /60)and 65%(39 /60)respectively,there was significant difference between the two groups(χ2 =10.75,P =0.00).The incidence rates of side effects in the treatment group and the control group were 1.7%(1 /60)and 6.7%(4 /60)respectively,there was no statistically significant difference between the two groups(χ2 =0.84,P =0.36).Conclusion Acupuncture combined with acu-point injection can significantly reduce the hiccup symptom score of post -stroke intractable hiccup patients on the 3, 5 and 7 days after treatment,and improve the total effective rate.

Objective To study the application of magnetic resonance T2 -mapping and diffusion weighted imaging(DWI)in diagnosis of early cartilage degeneration of the knee joint.Methods 56 patients with clinical intends to diagnosis of early osteoarthritis of the knee were set as observation group,another 56 healthy volunteers were selected as healthy control group.The subjects of the two groups were given knee MRI T2 mapping and DWI,the T2 acquisition value and ADC value of the two groups were analyzed and compared.Results In the observation group, the side of the femoral (37.18 ±4.09),lateral tibial (32.16 ±2.75)and hip (34.56 ±4.21)were significantly lower than those in the healthy control group[femoral side (49.87 ±5.02),tibial side (47.34 ±5.01),hip surface (51.23 ±5.19)](t =20.16,18.36,23.65,all P <0.05).Conclusion Magnetic resonance T2 -mapping and DWI imaging can be found in the early knee cartilage degeneration,can lead to the rise of T2 and ADC value,so there is no cartilage damage to the cartilage damage.
