BACKGROUND:Problems regarding the prosthesis in the horizontal plane and the rotation of the femur and tibia prosthesis on line are relatively weak. The distal femoral rotation axis is mainly the transepicondylar axis. Due to patient differences as wel as anatomy and intraoperative display, it is difficult to accurately locate the axis in the process of knee arthroplasty. OBJECTIVE:To investigate application of magnetic resonance technique in determining the axis of rotation of the distal femur, to provide reference and basis for femoral rotational alignment during total knee arthroplasty. METHODS:Data of 122 cases without knee joint disease, who were diagnosed and treated in the Department of Orthopedics of Nanyang City Center Hospital from September 2014 to October 2015, were analyzed. Magnetic resonance technique was used to measure femoral epicondyle axes (STEA), femoral epicondyle axes (CTEA), the anteroposterior axis (APL) and femoral shaft (PCL). Simultaneously, magnetic resonance technique was utilized to measure femoral ankle angle (PCA), ankle twist angle (CTA), axis vertical line and ankle axis angle (PAPA). Each data were tested three times, and the average value was calculatd. We analyzed the method of magnetic resonance technique to determine reference axis of distal femoral rotation. RESULTS ANDCONCLUSION: (1) Accuracy of the angle close to surgical transepicondylar axis: 3° PCL> CTEA > APL verticalline. (2) No significant difference in PCA was detected in two sets of measurements (P> 0.05). CTA and PAPA parameters in the first measurement by magnetic resonance imaging diagnosis were significantly lower than the second measurement (P< 0.05). (3) Results indicate that magnetic resonance technology provides ideal reference for distal femoral rotation, can accurately measure the CTA, PCA, PAPA andother indicators. It is a more reliable determination method and can be used in scientific determination of femoral rotational alignment reference axis in total knee arthroplasty. Except STEA, the accuracy of 3° PCL is highest.

Objective To assess the risk factors of intradialytic-hypotension (IDH) among maintaining hemodialysis (MHD) patients and to explore the relation between NT-proBNP and IDH,thus to provide clinical evidence for the prevention and treatment of IDH.Methods A total of 202 MHD patients during March 2009 to May 2009 in our dialysis center were enrolled in the study.Intradialytic blood pressure (BP) was measured during a 3-month period.IDH was defined as an event characterized by a sudden drop in systolic BP more than 20 mm Hg or in mean artery pressure (MAP) more than l0 mm Hg.Logistic regression analysis was used to assess the risk factors of IDH.ROC curve was used to evaluate the diagnostic efficacy of serum NT-proBNP.Results The incidence of IDH was 42.1％.One hundred and seventeen patients with no-IDH (＜1/10 hypotensive events per 3 months) were served as controls.Fifty-five patients with o-IDH (≥ 1/ 10 but ≤1/3 hypotensive events per 3 months) and 30 patients with f-IDH (＞1/3 hypotensive events per 3 months) were identified among 202 patients.Multivariate regression analysis showed that age,gender,ultrafiltration rate,serum NT-proBNP,serum albumin,aortic root dimension (AoRD) were associated with IDH among MHD patients.Serum NT-proBNP was positively correlated with IDH.The area under the ROC curve (AUC) of NT-proBNP was 0.76 (95％ CI 0.69 to 0.83,P＜0.01).The cut-off value of serum NT-proBNP for IDH was 1746.5 ng/L,with a sensitivity of 88.61％ and a specificity of 51.10％.Furthermore,the AUC of NT-proBNP for f-IDH was 0.65 (95％ CI 0.53 to 0.763,P＜0.01).The cut-off value of serum NT-proBNP for f-IDH was 8208.0 ng/L,with a sensitivity of 33.33％ and a specificity of 91.30％.Conclusions Elderly,female,high ultrafiltration rate,high level of serum NT-proBNP,hypoalbuminemia,shorter AoRD are independent risk factors of IDH among MHD patients.Serum NT-proBNP can be used as a predictor of IDH.

Objective To discuss the degenerative factors, the spinal segment distribution, and the mechanism in hyperextension injury of cervical spine. Method Eighty-nine patients with hyperextension injury of cervical spine were retrospectively analyzed by observing the degenerativelesion, the spinal cord segment with high signal in T2WI, and the location of facial trauma. Results Fifty-eight cases showed the disc hemiation which was the most common lesion, followed by 8 cases showing the calcification of the posterior longitudinal ligament. Besides, 7 cases presented the developmental stenosis of spinal canal, and also, 6 cases showed disc hemiation combined with the yellow ligament hypertrophy. The intervertebral level of the spinal cord with high signal in T2WI were distributed as follows:4 cases were at C2/3, of which onesuffered the forehead trauma; 12 cases were at C3/ 4, of which 10 had the forehead trauma, and one had the zygomatic trauma; 12 cases were at C4/5, of which 5 had the forehead trauma, one had both the zygomatic and the forehead trauma, and one had both the forehead and with the lower jaw trauma; 11 cases were at CS/6,of which 3 had the forehead trauma, 3 had the zygomatic trauma, and 2 had the lower jaw trauma. The location of the spinal cord with single high signal in T2WI did not correspond with the intervertebral disc level in 4 cases. For 10 cases the high signal in T2WI was found at two discontinuous segments. For 2 cases the 1 high signal in T2WI was found at over two segments. For 6 cases the high signal in T2WI was found at over three segments. Conclusions Disc hemiation is the most common underlyding factor in cervical hyperextension injury. The spinal level with high signal in T2WI was correlative to the impacted facial site. The shear force at the inflection point with or without the anterior-posterior compression force accounted for the cervical hyperextension injury.

Objective To study the clinical value of acoustic radiation force impulse imaging (ARFI) in patients with ischemic type biliary lesion (ITBL) after orthotopic liver transplantation. Methods Between July 2012 to January 2013, forty-one patients in General Hospital of the People′s Liberation Army were enrolled in this study who were admitted for post-transplantation follow-up. Among them, 15 patients were diagnosed as ITBL by ultrasonography. Besides conventional ultrasonography, ARFI was used to detect the shear wave velocity (SWV) of liver tissue at depth of 4 cm and 5 cm respectively. Simultaneously liver function test was performed. Independent-samples t test was performed to compare the difference of SWV between ITBL and non-ITBL group at the same depth. Paired-sample t test was performed to compare the difference of SWV for the same ITBL patient. Pearson correlation analysis was used in analyzing the relation between SWV and liver function. Results The average SWV in depth of 4 cm was (1.561±0.425) m/s and (1.121±0.160) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-3.173, P=0.01). The average SWV in depth of 5 cm was (1.608±0.545) m/s and (1.175±0.173) m/s in ITBL and non-ITBL group, respectively. Signiifcant differences were found among the ITBL and non-ITBL groups (t=-2.454, P=0.034). There was no signiifcant difference between SWV measurements at different depth for the same ITBL patient. For all patients, SWV at different depths were both strongly correlated with alkaline phosphatase (r=0.656, 0.667, respectively;both P=0.000) andγ-glutamyl transpeptidase (r=0.482, P=0.007;r=0.508, P=0.004). Conclusion The liver stiffness measurement is valuable for the clinical evaluation of post-transplantation ITBL.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

To evaluate the neuroprotective effect of nerve growth factor ( NGF ) on acute angle-closure glaucoma patients after trabeculetomy.METHODS: Patients with viral keratitis who underwent trabeculectomy in treatment of acute angle - closure glaucoma in Xiamen Eye Center of Xiamen University from December 2011 to October 2013 were selected and completed the treatment, 61 eyes of 45 cases were followed up. The treatment group of 23 cases (32 eyes) with acute angle-closure glaucoma patients were treated by NGF gel for 3mo after trabeculetomy, while in the control group 22 cases (29 eyes) were treated by normal saline replaced NGF. All patients were followed up for at least 12mo, visual acuity, perimetry, retinal nerve fiber layer ( RNFL) thickness and cup/disc ratio of the patients were followed up during the treatment. The safety of topical use of NGF gel was also evaluated.RESULTS:ln all patients, the intraocular pressure ( lOP) was successfully controlled under 21mmHg and the visual acuity was markedly increased in the affected eye after trabeculectomy. Compared with control group, the postoperative lOP and visual acuity had no significant differences in treatment group (P>0. 05). The average light sensitivity of perimetry and mean defect were better than that in control group postoperative 6 and 12mo; The results of optical coherent tomography ( OCT ) and Heiderburg Retina Tomography ( HRT )-Ⅲ showed that RNFL thickness was significantly greater than that in control group, while cup/disc ratio significantly less than that in control group postoperative 6 and 12mo. Ocular surface damage, corneal endothelium to reduce and other eye complication were no observed in treatment group.CONCLUSlON:Acute angle-closure glaucoma treated by NGF gel after operation is effective and safe.

AIM:To investigate the effect of reactive oxygen species(ROS)on the apoptosis of HepG2 cells induced by artesunate.METHODS:The effect of artesunate on the viability of HepG 2 cells was measured by MTT assay. The morphological changes of the apoptotic cells were observed by the method of Hoechst 33258 fluorescence staining.The apoptosis of HepG2 cells was analyzed by flow cytometry.DCFH-DA was used to detect the changes of ROS generation dur-ing the process of apoptosis.The protein levels of Bax ,Bcl-2,cleaved caspase-3 and cytochrome C(Cyt C)were deter-mined by Western blot.HepG2 cells were pretreated with apocynin and then Western blot was used to detect the expression of p47phox and p22phox,and ROS changes were analyzed by flow cytometry.RESULTS:Compare with control group,the cell viability was obviously inhibited after treatment with artesunate for 24 h(P<0.05).The nuclei were densely stained ,and the proportion of apoptotic cells was increased(P<0.05).ROS was increased significantly(P<0.05).The results of Western blot demonstrated that the expression level of Bax was increased ,Bcl-2 was decreased ,the ratio of Bax/Bcl-2 was increased ,and the protein levels of cleaved caspase-3 and Cyt C were increased.Pretreatment with apocynin reduced the expression of p47phox and p22phox and the generation of ROS in the artesunate treatment group.CONCLUSION:Artesu-nate induces the apoptosis of HepG 2 cells.The possible mechanism may be related to the increase in the generation of ROS.
