ObjectiveTo observe the therapeutic efficacy of warm needling plus Chinese medicinal fumigation and rehabilitation training in treating post-stroke shoulder pain.MethodSixty eligible patients were randomized into a treatment group (warm needling plus Chinese medicinal fumigation and rehabilitation) and a control group (rehabilitation training), 30 casesin each group. The Visual Analogue Scale (VAS), Fugl-Meyer Assessment Scale (FMA) and Barthel Index (BI) were respectively used to evaluate pain intensity, upper-limb motor function and activities of daily living, and the clinical efficacies were compared between the two groups.ResultAfter 30-day treatment, the improvements of shoulder pain intensity, upper-limb motor function and activities of daily living in the treatment group were more significant than that in the control group (P<0.05). There were no adverse events happened in the two groups.ConclusionWarm needling plus Chinese medicinal fumigation and rehabilitation training can effectively and safely mitigate shoulder pain, improve upper-limb motor function, and enhance the activities of daily living, and its therapeutic efficacy is superior to that of the control group.

AIMTo investigate the role of serine/threonine protein phosphatases in regulation of cell signal transduction on voltage-dependent sodium channels in rat trigeminal ganglion (TRG) neurons. METHODSWhole-cell patch clamp techniques were used to record the total sodium current (INa-T) and the tetrodotoxin-resistant sodium current (INa-TTX-R) before and after okadaic acid, a potent inhibitor of the serine/threonine protein phosphatases 1 and 2A, perfusion on adult rat TRG neurons. RESULTS1μmol*L-1 okadaic acid inhibited INa-T by (20±13)% (n=9, P<0.05) and INa-TTX-R by (4±3)% (n=6, P<0.05), respectively. The inhibition on INa-T was significantly greater than that on INa-TTX-R (P<0.05). Furthermore, 1μmol*L-1 okadaic acid produced significant 3-4 mV hyperpolarizing shifts in the conductance-voltage curves of INa-T, while it had no effect on that of INa-TTX-R. CONCLUSIONThe serine/threonine protein phosphatases take part in the regulation of total and TTX-R sodium channels on rat TRG neurons. In addition, small-diameter TRG neurons express various voltage-gated sodium channel with different sensitivity to okadaic acid.

Objective To study the influence of sivelestat sodium on platelets activity,injury and count during cardiopulmonary bypass (CPB)in dogs.Methods Twelve adult health dogs were randomly divided into control group (group C,n=6)and sivelestat sodium group (group S,n=6). Sivelestat sodium at 15 mg/kg was administrated intravenously before the establishment of CPB and then was maintained intravenously at 10 mg·kg-1·h-1 to the end of CPB in the group S,and the same volume of saline was used in the group S.The levels of neutrophil elastase (NE),malondialdehyde (MDA),granular membrane protein-140 (GMP-140),thromboxaneB2 (TXB2 ),the count of plate-lets and the hematocrit (Hct)were measured before CPB,15 and 45 min after cross-clamping and 30, and 60 min after aortic unclamping in both groups.Results The levels of NE,GMP-140,TXB2 at T2-T5 and MDA at T3-T5 were significantly higher than those at T1 in both groups;moreover the lev-els were significantly lower in group S than group C (P<0.05).The levels of Plt at T2-T5 were sig-nificantly lower than those at T1 in both groups;moreover the levels were significantly higher in group S than group C (P <0.05).Conclusion Sivelestat sodium reduced the levels of plasma NE, MDA,GMP-140,TXB2 inhibited the activation of Plt,and decreased the injury and consumption of Plt,which presents the protective effects for Plt during CPB.

Background:Accurate evaluation of the plain radiography of lower limb is critical for preoperative planning of total knee arthroplasty (TKA). We aimed to investigate the effect of femoral lateral bowing and rotation on the radiographic measurements of distal femoral condyle resection thickness (DRT) and the distal femoral resection valgus angle (FVA). Methods: We analyzed 246 three?dimensional femoral models generated from computed tomography images of 123 patients, acquiring projected contours in seven positions – 20° and 10° internal rotation; 0° rotation; 10°, 20°, 30°, and 40° external rotation – for each model. Medial and lateral condyle DRTs, femoral shaft lateral bowing angle (FBA), and distal FVA were determined for each position. Linear mixed effect model was used to determine the effect of degree of femur rotation on repeated measurements of DRT or FVA. Results: FBA significantly affected the FVA and DRT (Pearson's R = 0.767 and ?0.408, respectively; P < 0.000). Samples were divided into three groups according to the FBA measured in neutral position: FBA <0°: DRT 3.75 ± 1.30 mm, FVA 4.53° ± 1.27°; FBA >0° but <3°: DRT 3.39 ± 1.31 mm, FVA 5.92° ± 1.31°; FBA >3°: DRT 2.22 ± 1.31 mm, FVA 7.37° ± 1.31°. From simulated 20° internal rotation to 40° external rotation in each femoral model, the average variation ranges of radiographically measured DRT, FVA, and FBA were 0.50 ± 0.28 mm, 2.93° ± 0.96°, and 10.33° ± 1.90°, respectively, with no significant differences among the FBA groups. The degree of femoral rotation significantly affected the FVA (F = 62.148, P < 0.000), whereas there was no effect on condyle resection thickness (F = 0.4705, P = 0.494). Conclusions: Axial femoral rotation has less effect on radiographic measurements of differences in the DRT than on those of the distal FVA.

Methods A prospective study is perfonued here to assess whether ~(18)FDG PET-CT can improve the diagnostic accuracy in lymph node metastasis for patients with advanced esophageal carcinoma.Thirty patients had undergone esophagectomy with extensive lymph node dissection.PET-CT findings were compared with that d CT with pathological finding as the final say.Results All patients were operated successfully without peri-operative complications.The pathological examination conformed metastasis in 22 patients and 49 out of 243 excised lymph nodes.In CT analysis,the sensitivity was 40.8%,specificity was 96.9%,with a diagnostic accuracy of 85.6%, The positive and negative predictive value was 76.9%,86.4% respectively;PET-CT resulted in a sensitivity of 93.9%,specificity of 91.2%,accuracy of 91.8%.The positive predictive value was 73.0% and negative predictive value was 98.3%,The difference of sensitivity(P＜0.001),accuracy(P＜0.05)and negative predictive value between the two radiological modalities was statistically significant(P＜0.001).Conclusions With a high sensitivity and accuracy in the diagnosis of lymph node metastasis,PET-CT appears necessary in preoperative examination for advanced esophageal carcinoma in the hope that surgical treatment be guided by the results of PET-CT,especially for the elder patients with poor pulmonary function or heart or brain complications. Moreover,it could be used as the basis of the conformal radiation therapy planning for inoperable patients.

Objective To evaluate the clinical value of 18-fluoro-deoxyglucose positron emission tomography-CT(~(18)FDG PET-CT) for recurrence and metastasis in treated esophageal carcinoma (EC). Methods A retrospective study is done on 37 previously treated EC patients who underwent PET-CT scans to detect recurrent or metastatic lesions.The diagnostic accuracy of ~(18)FDG PET-CT was assessed with the help of pathological finding as well as clinical or follow-up data.Results Fourty-six sites of recurrence were finally confirmed in 37 patients by cytology,pathology or follow-up data.The sensitivity,specificity and accuracy of PET-CT in detecting recurrence of all sites were 93.5% (43/46),76.9% (20/26) and 87.5% (63/72),respectively.Two false-positive findings were found both at the anastomosis and hilar nodes,which caused the decrease in the overall specificity,especially that locally.The analysis of standard uptake value (SUV) demonstrated that patients with recurrence or who died during follow-up had higher SU- Vs compared with the control group.Condusions ~(18)FDG PET-CT is highly effective in detecting recur- rence in previously treated EC patients despite the low specificity at local sites.The analysis of stardard up- take value(SUV) provides incremental value in prognosis for this patient cohart.
