According to morphological and microscopic characteristics, a high-efficient decolorizing fungus, the strain Asaw117, was identified as Aspergillus awamori. Selecting eight different dyes from Azo dyes, anthraquinones dyes and oxygen Quinones dyes, the decolorizing assays of various dyes showed that the strain Asaw 117 was the highest decolorizing potential to 0.1 g/L Vat Blue RSN, the discoloration rate up to 100 percent. Comparing to different kinds of medium and several of carbon and nitrogen sources, the strain had the best decolorizing efficient although grew slower in the Czapek medium, otherwise, grew quicker and decolorizing efficient lower in the PDF medium. It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources. So the strain has good potential for the dyeing wastewater treatment

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

Objective To determine the clinical efficacy of limited internal fixation with posterior titanium plates for unstable atlas fractures.Methods A retrospective case series analysis was performed for 29 patients with unstable atlas fractures immobilized using the posterior titanium plate from January 2011 to November 2014.There were 22 males and seven females,with a mean age of 41.5 years (range,17-68 years).Ten patients were diagnosed with 1/2 ring Jefferson fractures,12 anterior 1/2 Jefferson fractures and seven patients posterior 3/4 Jefferson fractures.Frankel neurological performance scale was grade E in all patients.Operation time,amount of bleeding during operation and postoperative complications were recorded.X-ray and CT were performed to identify the fusion,internal fixation location and atlantoaxial stability.Visual Analogue Scale (VAS) for craniocervical pain and cervical range of motion were evaluated.Results Mean duration of procedure was (86.6 ± 7.8) min (range,68-122 min) and mean blood loss was (120.0 ± 25.3) ml (range,90-400 ml).No vascular and neurologic complications were noted.All patients were followed up for (22.5 ± 18.0)months (range,12-32 months).CT scans confirmed bony union in all patients 6 months after operation.No plate-related complications,implant lessening and implant breakage occurred during the follow-up.Postoperative VAS [(1.9 ± 1.1) points] was significantly lower than that before operation [(7.2 ± 1.4) points] (P ＜ 0.05).At the last follow-up,the ranges of cervical flexion-extension [(81.3 ± 22.2) °] and rotation [(152.4 ±38.7) °] were close to the normal range.Conclusion Limited internal fixation with posterior titanium plates is a safe and effective surgical method that contributes to good reduction and maximal preservation of cervical physiological motion.

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.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.

METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.

RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.

CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.

Objective To observe the effect of dihydromyricetin of ampelopsis grossedentata on lipid metabolism and antioxidation in atherosclerosis (AS) rats. Methods Sixty Wistar rats were randomly divided into five groups (n = 12 each):normal control group, model control group, positive control group, high dose dihydromyricetin group (40 mg·kg-1 ) and low dose dihydromyricetin group (10 mg·kg-1 ). Except normal control group, rats in the other groups were injected with a single dose of vitamin D3(600 000 U·kg-1 ) and loaded with high fat diet to establish AS model. Simvastatin (5 mg·kg-1 ) was intragastrically administered to positive control group. High and low dose dihydromyricetin groups received intragastric administration of 40 and 10 mg·kg-1 dihydromyricetin, respectively. Equal volume of purified water was given to normal and model group. After 24 weeks of administration, serum levels of lipids, activities of superoxide-dismutase (SOD) and malonicdialdehyde (MAD) were determined. Results As compared with model control group, triglycerides (TG) of high and low dose dihydromyricetin groups was decreased [(191. 65±101. 10) vs. (111. 10±29. 29) and (120. 55±38. 12) mg·L-1 , respectively], total cholesterol (TC) was decreased [(151. 64±33. 62) vs. (148. 49±30. 14) and (118. 90±27. 38) mg·L-1 ], and high density lipoprotein cholesterol (HDL-C) was increased [(1. 29±0. 68) vs. (2. 10±0. 70) and (1. 62±0. 61) mmol·L-1 ], low density lipoprotein cholesterol (LDL-C) was decreased [(5. 01±1. 33) vs. (3. 97±0. 78) and (4. 28±0. 79) mmol·L-1 ], activity of SOD was increased [(141. 03±42. 52) vs. (187. 97±42. 08) and (150. 99±46. 17) U·mL-1 ], and MDA was decreased [(20. 51±3. 81) vs. (17. 64±1. 54) and (18. 52± 3. 42) nmol·mL-1 ], with significant differences (P<0. 05, P<0. 01). Conclusion Dihydromyricetin can reduce the level of serum lipid, improve antioxidation activity, and has therapeutic effect for atherosclerosis.

Objective To investigate the incidence and treatment of posttraumatic cauda equina herniation associated with lumbar fracture.Methods A retrospective analysis was performed on 416 patients admitted due to lumbar burst fracture between June 1,2008 and June 1,2011.All the patients had been operated on via anterior or posterior approaches.Data collected included demographics,injury mechanism,radiographs,surgical procedures,outcomes and follow-up.Incidence of cauda equina herniation was documented.Results All surgeries were uneventful.Cauda equina herniation was observed in 49 patients (11.8％) during surgical exploration.Anterior surgery was done on 115 patients and found 7.8％ incidence of cauda equina herniation (9/115).Posterior surgery was done on 301 patients and found 13.3％ incidence of cauda equina herniation (40/301).There were 40 patients combined with laminar fracture and 38 of them had cauda equina herniation with the incidence rate of 95％.Among the 49 patients with cauda equina herniation,44 (90％) had neurological deficit and 5(10％) were found with good neurological function but significant proportion of cauda equina rootlets entrapped in the lamina fracture.Conclusions Lumbar burst fracture combined with neurological deficit and laminar fracture may increase the risk of posttraumatic cauda equina herniation and should be paid attention.Operations should be performed with caution to avoid further nerve damage.
