[Objective] To discuss the clinical significance of simple synovial tuberculosis treated and diagnosed by arthroscopy. [Methods] A review study of 8 patients with simple synovial tuberculosis from September 1998 to September 2004. The 8 cases with the main clinical manifestation of articular swelling were confirmed as simple synovial tuberculosis by arthroscopic examination and arthroscopic synovectomy in pathology. [Results] The 8 cases were definitely diagnosed by arthroscopy pathologically. The average follow-up period was two years and four months. For all of the 8 cases, the articular symptoms disappeared, articular function recovered well and the therapeutic effect was satisfactory. [Conclusion] Arthroscopic examination is an effective method to diagnose synovial tuberculosis at early stage. Synovectomy with arthroscopy can remove the pathological synovial membrane and is beneficial to the control of the local tubercular focus.

Objective To study the effect of transcranial ultrasound (US) on arterial recanalization in acute ischemic stroke patients.Methods Patients with acute middle cerebral artery (MCA) main stem occlusion after 6 h were randomized into a target group receiving low-frequency,pulse-wave mode,transcranial US for 30 min or a control group.All were treated with intravenous urokinase for thrombolysis.Transcranial doppler sonography (TCD) was used to document vascular occlusion and confirm recanalization at 2 h and 24 h after treatment,and the patients were evaluated using the National Institutes of Health Stroke Scale ( NIHSS).Results Recanilization (complete or partial) after 2 hours was significantly higher in the US group (44.4％) compared with the control group ( 10.5％ ).Recanalization had occurred in 50％ of the US group 24 hours after treatment compared with 15.7％ of the controls.At 2 h after treatment,33.3％ of the US group and 5.5％ of the controls had improved at least 4 points on the NIHSS assessment.After 24 hours the figures were 44.4％ and 10.5％.After 3 months,11 subjects from US group (61.1％ ) had a modified Rankin score ≤2 compared with 4 subjects (21％) from the control group.Conclusions In acute ischemic stroke,transcranial US has positive effects on recanalization and neural function.

Objective To explore the effect of galanin ( GAL) on locus coeruleus ( LC) neurons from neonatal rat and mechanism with its receptor GalR and potassium channel.Methods Brain slices from neonatal rats were prepared and the resting membrane potential and spontaneous action potential of LC neurons were recorded with whole cell patch-clamp configuration.GAL, AR-M1896 and potassium channel blockers were bath applied with different concentration.Results Bath application GAL induced hyperpolarization and inhibited firing rate of LC neurons.However, AR-M1896 ( a selective GalR2 agonist) did not induce significant effect on LC neurons, only at very high concentration(1μM) it induced slight hyperpolarization and reduced firing rate.The inhibitory effect of GAL was partially blocked by TEA ( an antagonist of voltage-dependent potassium channel) and significantly blocked by BaCl2(an antagonist of inward-rectifying potassium channels), while other potassium channels blockers such as Glybenclamide(ATP-sensitive potassium channel blocker),Charybdotoxin(large-conductance Ca2 +-activated K + channels blocker),Apamin(small-conductance Ca2 +-activated K +channels blocker) failed to block it.Conclusion GAL inhibits LC neurons from neonatal rats, mainly through GalR1.TEA-sensitive potassium channels and inward-rectifying potassium channels, but not ATP-sensitive potassium channel and calcium-activated potassium channel, are involved in this inhibition.

Objective To investigate the efficacy of acupuncture combined with doctor-nurse cooperation mode on stroke-associated pneumonia in patients with acute stroke. Methods 67 patients of acute stroke within 1 week in our hospital from March, 2013 to January, 2015 were randomly divided into control group (n=35) and treatment group (n=32). Both groups received neurological routine treatment and systematic rehabilitation training by professional physiotherapists under general nursing mode. The treatment group received acupuncture treatment under doctor-nurse cooperation mode additionally. Incidence of stroke-associated pneumonia, swallow function and aspiration rate were recorded. Results Compared with the control group, the incidence of stroke-associated pneumonia significantly decreased in the treat-ment group after treatment (χ2=4.615, P=0.032). The retention volume of epiglottic vallecula and pyriform sinus (tdilute barium=21.01, tthick barium=19.85), the duration of pharynx period (tdilute barium=17.03, tthick barium=13.68), and the start time of pharynx period (tdilute barium=19.63, tthick barium=17.86) were less in the treatment group than in the control group (P<0.05). In the test of dilute barium, the aspiration rate was lower in the treatment group than in the control group (χ2=4.03, P=0.044), however, there was no significant difference between 2 groups in the test of thick bari-um and solid food (P>0.05). Conclusion Acupuncture combined doctor-nurse cooperation mode may decrease the rates of aspiration and stroke-associated pneumonia in acute stroke patients through improving their swallow function.

Objective The objective of this study was to compare the differences between Volumetric Modulated Arc Radiotherapy(VMAT)and Fixed Field dynamic Intensity Modulated Radiotherapy(dIMRT)in dose distribution of target and organ at risk and treatment time,and to provide basis for clinical treatment.Methods Ten patients with postoperative of cervical carcinoma were selected,VMAT and seven fields dIMRT plans were designed for each patient in Monaco 5.11 planning system.We compared the differences of dose distribution of target and organ at risk,monitor units and treatment time between VMAT and 7dIMRT.Results The average dose of target for VMAT plan(46.86 Gy)was higher than that of 7dIMRT plan(46.68 Gy)(P<0.05).The percentage of the V10 and V20 of rectum and the V30 of small intestine in VMAT plan was 0.63%,3.34% and 4.14% higher than that in 7dIMRT plan,respectively(P<0.05).The conformal index(CI),homogeneity index(HI)of PTV and the other exposure dose of organ at risk for both plans were no significant differences.The average monitor units and treatment time of VMAT plan were 13.4% and 50.6% than that of 7dIMRT plan,respectively(P<0.05).Conclusion The dose distribution of VMAT plan is better or equal to that of 7dIMRT plan,but the monitor units and treatment time of VMAT plan is decreased significantly,we suggest that VMAT plan should be used for postoperative of cervical carcinoma in clinical.

Objective The effectiveness on the enrichment of nuclear red blood cells(NRBC) in umbilical cord blood by polyvinylidene difluoride membrane was investigated with intervention on membrane ionic channels.Methods NRBC was isolated by the isolation solution with a density of 1.067 g/ml.The rates of the cell enrichment using verapamil and furosemide intervention by discontinuous density centrifugation were examined by flow cytometry.The NRBC that past through PVDF membrane with pore size of 5 ?m were checked and quantified by nested-PCR.Results The optimal centrifugation density was 1.067 g/ml.The mean purity of NRBC after centrifugation was 2.54%,yet the purity after intervention increased to 9.36%(3.7-fold increment).The NRBC passing through PVDF membrane was from 0.83% to 6.15%,with enrichment of 7.4 times.When NRBC was 120 cells/ml,the density of the nested PCR products increased by nearly 4 times after intervention(4.48 vs 17.78).Conclusions Verapamil and furosemide could affect the morphology of cells and promote the rate of NRBC enrichment.

Three hundred cerebrovascular disease (CVD) patients (disease onset <3 days) were evaluated for serum C-reactive protein (CRP) level at admission, and Scandinavian Stroke Scale (SSS) or Oxford Handicap Scale (OHS) at baseline and 3 months. Based on serum CRP levels, the participants were divided into group A [CRP(1.20 ±0.35)mg/L], group B[CRP(4.98 ± 1.08) mg/L] or group C[CRP (19.34±12.27)mg/L]. Our results showed that serum CRP level was positively correlated with SSS (r = 0.39 or0.43, both P<0.01) and OHS (r=0.40 or0.42, both P<0.01) at3 months. Thus, evaluating serum CRP level within 3 clays of disease onset might be helpful in predicting clinical outcomes of CVD patients.

Objective To evaluate the precision of image guided radiotherapy (IGRT) for vertebra metastasis.Methods Cone-beam computed tomography (CBCT, ELEKTA SynergyTM) scanning was performed to 15 patients with vertebra metastasis treated with three dimensional conformal radiation therapy (3DCRT) or intensity modulated radiation therapy (IMRT).CBCT images were then compared with corresponding planning images to calculate the position errors.The isocenter was adjusted based on the errors calculated , CBCT scanning was re - performed , and the new - errors were then calculated .Results Compared to the firstly collected CBCT images, the average errors of 4 cases of cervical bone metastases in x (left-right), y (cervical-caudal), and z (anterior-posterior) directions were 1.8 mm, 0 mm and 3.6 mm respectively.After adjusting the isocenter, the new-errors were reduced to 0.1 mm, 0.4 mm and 0.3 mm.For 11 cases of thoracic and lumbar bone metastases, the average errors in x, y, and z directions were 1.9 mm, 0.1 mm, and -2.1 mm, respectively.While the new-errors were reduced to 0.9 mm, 0.5 mm and -0.3 mm.Conclusions IGRT can improve the precision of radiotherapy for vertebra metastasis to less than 2 mm, which provides a possibility of dose escalation in GTV while reduce the dose in the spinal cord.
