BACKGROUND: Balance disorder of the two neurotransmitters-dopamine and glutamic acid in striatum, participates in the pathogenic process of Parkinson disease. Whether or not electroacupuncutre can regulate the content of glutamic acid in striatum in the treatment of Parkinson disease so as to recover the balance of the two neurotransmitters is needed further investigation.OBJECTIVE: To observe the changes of content of excitatory amino acid (glutamic acid) in striatum of rat with Parkinson disease and the effects of electroacupuncture intervention on these changes.DESIGN: Randomized controlled trial.SETTING: Teaching and Research Section of Acupuncture and Moxibustion, Hubei University of Traditional Chinese Medicine.MATERIALS: The experiment was completed in Laboratory for Important Subject (Acupuncture and Moxibustion) of Hubei University of Traditional Chinese Medicine from February to August 2002. A total of 40 healthy SD rats were selected and randomly divided into 4 groups, namely, normal group, model group, sham operation group and electroacupuncutre group with 10 in each group.METHODS: Model group: Rotation model of rat with Parkinson disease was established by method of chemical damage on right substantia nigra.Sham operation group: Method of sham operation was the same as model group, and 3.4 μL physiological saline was injected. Electroacupuncture group: Electroacupuncture treatment was given after model establishment;took Atlas of Experimental Animal Acupoints as reference, selected the acupoints of Taichong and Fengfu, pierced with needles which were connected with G6805 electroacupuncture therapeutic apparatus under the condition of continuous waves and frequency of 2 Hz for 30 minutes, once a day for consecutive 7 days, then detected the content of glutamic acid.MAIN OUTCOME MEASURES: Content of glutamic acid in bilateral striatum of rat in normal group, sham operation group, model group and electroacupuncture group, which was detected by automatic amino acid analyzer.RESULTS: The content of glutamic acid in right striatum of rat in model group was significantly higher than that in contralateral striatum, normal group and sham operation group [the contents of glutamic acid in model group, contralateral striatum, normal group and sham operation group were (101.6±7.49), (71.4±5.65), (61.8±4.38), (62.6±5.21) μg/g respectively,P ＜ 0.01]. The content of glutamic acid in right striatum in electroacupuncture group was significantly lower than that in model group [the contents of glutamic acid in electroacupuncture group and model group were (83.7±5.68), (101.6±7.49) μg/g respectively, P ＜ 0.05], but still higher than that in normal group and sham operation group (P ＜ 0.05). There was no significant difference between the contents of glutamic acid in left striatum in each group (P ＞ 0.05).CONCLUSION: Excitatory amino acid participates in the pathogenic process of Parkinson disease. Therefore, one of the approaches of electroacupuncture treatnent for Parkinsonism is reducing the release of excitatory amino acid.

[Objective]To explore the effective treatment method of the articular fracture in distal radius.[Method]Severely comminuted AO type-C3 intra-articular fractures of the distal end of the radius were treated with combined internal and external fixation.The Gartland and Werley system and the Green and O'Brien system were used for comparison of the pre-operative and after operative evaluation.Total articular congruity had been assessed with both clinical rating systems.[Result]At a mean of ninteen months following-up,the mean arc of flexion-extension was 78% of that on the uninjured side and the mean grip strength was 82% of that on the uninjured side.The mean total articular incongruity(the gap plus the step-off)averaged 2 mm,and the radial length was restored to a mean of 11 mm.According to the Gartland and Werley demerit-point system,seventeen of the patients had a good or excellent result.According to the modified Green and O'Brien clinical rating system,eleven had a good or excellent result.Postoperative total articular incongruity had a moderately strong correlation with the outcome as assessed with both clinical rating systems.[Conclusion]Open reduction and combined internal and external fixation of AO type-C3 fractures can restore radiographic parameters to nearly normal values,maintain reduction throughout the period of fracture-healing,and provide satisfactory functional results.

Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.

Objective To investigate the effects of extracellular ATP on the recovery of motor function after spinal cord injury in rats.Methods Twenty healthy adult rats were randomly divided into two groups after contusion injury was performed by the weight drop method at T10 with Allen impactor.Group A(ATP group) and group B(control group) each had ten rats.At days 1,3,7,14 and 28 after injury,the recovery of motor function after spinal cord injury in rats was assessed with modified Tarlov scores and slanting board test.Results Modified Tarlov scores and slanting board test were better in group A than in group B after spinal cord injury in rats.Significant difference was found in modified Tarlov scores and slanting board test between the two groups at days 14 and 28 after injury(P

Objective To investigate the associated risk factors of postoperative complications after rad?ical resecting of colorectal cancer. Methods The clinical data of 237 patients with colorectal cancer performed radical resection in the Second Affiliated Hospital of Kunming Medical University from January 2011 to Decem?ber 2014 were analyzed retrospectively. The incidence of postoperative complications was analyzed,and the relat?ed factors were analyzed by single factor and multi factor correlation analysis. Results The postoperative com?plications occurred in 114 cases of 237 patients( 48. 1%) . Univariate analysis showed that the age more than 70 years old,preoperative comorbidity,intraoperative blood loss,surgeon’ s experience,combined evisceration or en?larged evisceration were related to postoperative complications ( P = 0. 033, 0. 014, 0. 045, 0. 028, 0. 040 ) . Compared with the patients without complications,the postoperative anal exhaust time,length of stay was longer of the patients with complications((3. 7±1. 6) d vs. (3. 2±1. 4) d,P=0. 035;(21. 3±6. 5) d vs. (12. 1 ±2. 4) d,P=0. 001). Logistic regression analysis showed that depth of tumor invasion(P=0. 001),preoperative comorbidity including NRS>3 points (χ2 =8. 903, P=0. 003 ) , anemia and hypoproteinemia (χ2 =3. 494, P=0. 048) ,hypertension complicated with type 2 diabetes mellitus(χ2=5. 418,P=0. 026) ,not complete intesti?nal obstruction(χ2=8. 376,P=0. 003),mild and severe ventilation dysfunction(χ2=6. 331,P=0. 011) and WBC<3. 9×109(χ2=4. 256,P=0. 041) were closely related to the occurrence of complications. The rate of post?operative complication of laparoscopic group and open group had no significant difference( 44. 4%( 64/144) vs. 47. 3%(44/93),P>0. 05) . Conclusion Age>70 years old,preoperative comorbidity,intraoperative blood loss,surgeon`s experience,combined evisceration or enlarged evisceration are main risk factors for patients per?formed colorectal cancer radical resection,but laparoscopy?assisted radical resection is not the risk factor.

OBJECTIVETo study clinical effects of unilateral pedicle screw-rod system fixation combined with the single the cage of interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor.

METHODSFrom February 2010 to December 2011, 39 patients with lumbar degenerative instability after invalid conservative treatment were treated with unilateral fixation combined with interbody fusion via the paraspinal intermuscular approach under MAST Quadrant retractor. The indexes such as the operative time, blood loss, complications, VAS pain scores, JOA (subjective symptoms of low back pain,lower limb pain and numbness, sensory disturbance, movement disorders) scores, modified Macnab criteria for curative effect evaluation were observed before treatment, at the 1st month after treatment and the latest follow-up. The intervertebral fusion was studied on the X-ray at the latest follow-up.

RESULTSAll the patients were followed up, and the mean during was (22.3 +/- 8.6) months. The operation time was (138 +/- 46) min, and the amount of bleeding was (335 +/- 152) ml. There were no complications such as cerebrospinal fluid leakage and spinal nerve injury during operation, and no incision infection after operation. The VAS pain score was reduced from preoperative 7.93 +/- 1.27 to 2.05 +/- 1.18 on the 1st month after operation and 1.89 +/- 0.42 at the latest follow-up. The JOA total score was improved from preoperative 1.59 +/- 0.42 to 8.86 +/- 0.37 on the 1st month and 9.02 +/- 0.29 at the latest follow-up. According to modified Macnab criteria, there were 17 cases got an excellent result, 19 good, 3 case fair. Thirty-five patients got intervertebral bony fusion at the latest follow-up.

CONCLUSIONUnilateral pedicle screw-rod system fixation combined with single cage interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor is a safe, minimally invasive, satisfactorily effective methods to treat lumbar degenerative instability.
