Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

Objective: To compare the efficacy of different treatment protocols in treating transient synovitis of the hip (TSH) in children and to optimize the clinical treatment strategy for this condition. Methods: Ninety kids with TSH were divided into a control group, a chiropractic group and a chiropractic plus foot bath group using the random number table method, with 30 cases in each group. The control group was treated with conventional traction; the chiropractic group was given chiropractic treatment based on the control group; the chiropractic plus foot bath group was given Chinese medicine foot bath based on the chiropractic group. Traction and foot bath were conducted once daily while chiropractic was done once every other day, all with 14 d as a treatment course for a total of two courses. Changes in the visual analog scale (VAS) score and range of motion (ROM) of the hip joint in the three groups were observed, and the efficacy was compared. Results: The total effective rate was 93.3％ in the chiropractic plus foot bath group, versus 76.7％ in the chiropractic group and 66.7％ in the control group, and the total effective rate was notably higher in the chiropractic plus foot bath group than in the other two groups (both P<0.05). Respectively after the first and second treatment course, the VAS score decreased significantly in each of the three groups compared with that before treatment (all P<0.01), and the ROM of the hip joint in flexion increased significantly (all P<0.01). After two treatment courses, the VAS score was lower in the chiropractic plus foot bath group than in the other two groups (both P<0.05), and its ROM of the hip joint in flexion was larger than that in the other two groups (both P<0.05). Conclusion: Based on traction, chiropractic plus Chinese medicine foot bath can effectively reduce pain and improve motor function of the hip joint in treating TSH.

Objective To investigate the prevalence,missed diagnosis rate and causes of acute kidney injury (AKI) in hospitalized children,and its impact on hospitalization cost,length of stay and outcome.Methods The data of children admitted in Children's Hospital Affiliated to Capital Institute of Pediatrics from December 1st to 31st 2014 were collected,and those whose serum creatinine (Scr) were measured at least two times were selected.Patients were diagnosed as AKI according to the diagnostic criteria of 2012 Kidney Disease:Improving Global Outcomes,then divided into AKI group and non-AKI group,the former of which was further divided into AKI1 group (Scr peak value in normal range) and AKI2 group (Scr peak value above normal range).The causes and impact of AKI on hospitalization cost,length of stay and outcome in different groups were compared and analyzed.Results (1) Among 921 patients with at least two Scr results,170 patients met with the diagnostic criteria of AKI,including 100 males and 70 females.There were 112(65.9％) in AKI stage 1,43(25.3％) in stage 2,and 15(8.8％) in stage 3.The overall prevalence of AKI was 18.5％.With only 7cases getting diagnosed,the diagnostic rate was 4.1％,while 95.9％ of patients missed diagnosis.(2)Among AKI patients,67 cases had pre-renal causes,103 cases had intra-renal causes and mixed factors.100(58.8％) cases got complete recovery,34(20.0％) cases recovered partially and 36(21.2％)cases did not improve,including 4 cases of death.(3) The prevalence of AKI among those below 1-year old was higher than children elder than 1-year (23.0％ vs 15.5％,P=0.004).The prevalence of AKI in surgical ward was higher than medical ward (30.7％ vs 15.8％,P ＜ 0.001).(4) Compared with those in non-AKI group,there was lower age [1.1(0.2,3.5) year vs 2.0(0.3,4.9) year] and higher hospitalization time[12.5(8.0,20.0) d vs 8.0(6.0,11.0) d],hospitalization costs [25 279.2(13 822.8,48 856.7) yuan vs 12 616.9(8680.1,19 345.1) yuan] and mortality (2.4％ vs 0.3％) in AKI group (all P ＜ 0.05).(5) There were 126 cases in AKL group and 44 cases in AKI2 group.The costs of hospitalization,outcome and mortality showed no difference between two groups (all P ＞ 0.05).The hospitalization time in AKI2 group was shorter than that in AKL group (P=0.038).Conclusions Among hospitalized children the missed diagnosis rate of AKI is high.Pre-renal factor is the main cause of AKI.Children younger than 1-year old are more susceptible to AKI.AKI children have lower age and higher hospitalization time,hospitalization costs and mortality than non-AKI children.The effect of Scr fluctuation within normal levels needs to be further studied.

Objective To investigate the nutritional management level of Department of Clinical Nutrition in elderly inpatients through analyzing the actual hospital dietary intakes in elderly inpatients in Peking Union Medical College Hospital from 2013-2015.Methods Using continuous sampling, the nutrients contents and the eating rates of hospital meals ordered by the elderly inpatients on the 1st, 15th, 29th of every month from May 2013 to October 2015 were selected.The intake levels of energy, protein, calcium, vitamin A, vitamin B1 , and vitamin C were calculated and compared with the Chinese dietary reference intakes (DRIs).The nutritional in-take differences between diabetes diet and the basic hospital diet were also compared.Results A total of 90 days of hospital dietary data from 8 402 elderly inpatients were included in the study.The average eating rate was (50.1 ±4.2)%, which was lower than the general eating rate of the hospital [ (59.0 ±4.0)%, P<0.001]. Only protein intake from hospital diet reached the requirement target [male (103.1 ±47.3)%, femal (98.3 ± 33.8)%].Individual compliance rates were 63.2%and 59.8%, respectively, while the other kinds of nutrients were lower.The compliance rates of energy [ (73.3 ±26.3)%vs.(62.1 ±38.2)%, P<0.001] and ma-jor nutrient intake [ protein: ( 119.1 ±41.2 )% vs.( 93.3 ±65.1 )%, P <0.001; calcium: ( 55.5 ± 26.7)% vs.(34.3 ±34.2)%, P <0.001; vitamin A: (75.2 ±48.3)% vs.(57.4 ±97.1)%, P<0.001;vitamin B1:(76.4 ±38.2)%vs.(52.1 ±46.6)%, P<0.001;vitamin C:(92.2 ±51.4)%vs. (49.3 ±55.0)%, P<0.001) in diabetes diet group were significantly higher than those in the basic hospi-tal diet group.Conclusions The nutritional intakes from hospital diets may not meet the nutritional require-ments based on DRIs in elderly inpatients.Medical diet designed by physicians and dietitians should be ex-panded to improve the nutritional management level for these patients.

OBJECTIVETo explore the effect of the level of lipid peroxidation and biomechanical properties after chronic treating with tetrahydrobiopterin (BH4) in thoracic aorta of hyperlipemia (HL) rats.

METHODSHL rats were given BH4 chronically. The opening angle in the zero-stress state and the relationship between pressure and diameter (P-D) of mesenteric artery were measured by computer image 8, 16, and 24 week-old respectively.

RESULTSTreating with BH4 chronically from 8 week-old in HL rats, there was a significant increase in the zero-stress state of opening angle of thoracic aorta. The P-D curve of mesenteric artery moved upward.

CONCLUSIONTreating with BH4 prevented the structure and function of artery from abnormal changing, and attenuated lipid peroxidation in HL rats.

OBJECTIVETo investigate prevalence, location, negotiation and the effect of operating microscope (OM) in the treatment of the second mesiobuccal canal (MB2) in maxillary molars.

METHODS113 maxillary molars were studied. The crowns of the teeth were removed 1 mm above the chamber bottom for searching MB2 canal. Initially location and negotiation of MB2 canal were attempted without OM. Teeth in which MB2 canal were not located or negotiated were further explored under OM. Canal orifices including MB orifice, MB2 orifice and palatal orifice were filled by red gutta-percha cones, then the teeth were scanned by scanner. The images were analyzed by Image-Proplus 4.0 software to measure the relationship between MB2 canal and other canals.

RESULTSThe MB-MB2 distance is (1.47 +/- 0.54) mm, MB-P distance is (5.77 +/- 0.66) mm, the vertical distance from MB2 to MB-P line is (0.53 +/- 0.28) mm, the angle between MB-P line and MB-MB2 line is 23.07 degrees +/- 13.08 degrees. MB2 orifices were located in 70 teeth (61.9%) and negotiated in 53 teeth (46.9%) without OM. With OM, additional MB2 orifices were located in other 6 teeth, 4 were negotiated; and 2 were negotiated in which MB2 canal were not negotiated without OM.

CONCLUSIONSMB2 canal can be located in 67.3% and negotiated in 52.2% of maxillary molars. Ability to locate and negotiate MB2 canal is facilitated by OM. The MB2 canal was located less than 1 mm mesially to the MB-P line and 2 mm palatally from the MB orifice.
