Objective: To explore the relevant factors of acquired swallowing disorders in adult patients after cardiac surgery. Methods: A Jiatian water swallowing screening test was conducted for adult patients after cardiac surgery in our hospital from 2015-03 to 2015-09. There were 32 patients with acquired swallowing disorder deifned as Case group and meanwhile 420 patients without swallowing disorder at the same word deifned as Control group. Non-conditional Logistic regression analysis was applied to study the relevant factors for acquired swallowing disorders. Results: The overall incidence of acquired swallowing disorders was 7.08%. Multi Logistic regression analysis presented that duration of endotracheal intubation (OR=1.060,P<0.001), pre-operative arrhythmia (OR=2.780,P=0.019), NYHA grade (OR=1.789, P=0.033) and Euroscore (OR=1.216,P=0.040) were the relevant factors for the occurrence of acquired swallowing disorders in adult patients after cardiac surgery. Conclusion: Medical professionals should pay special attention to patients with above mentioned risk features at post-operative drinking to reduce the complications of acquired swallowing disorders.

In this study, ultra performance liquid chromatography-quadrupole-time of flight mass spectrometer-MS^E (UPLC-Q-TOF-MS^E) combined with UNIFI analysis platform was used to rapidly analyze and identify the metabolites of hederagenins 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin D) and oleanolic acid 3-O-α-L-rhamnosyl-(1→2)-[β-D-glucopyranosyl-(1→4)]-α-L-arabopyranoside (Pulsatilla saponin B₇) and hederagenins 3-O-α-L-rhamnosyl-(1→2)-α-L-arabopyranoside (Pulsatilla saponin BD) in plasma and colonic tissue of normal and ulcerative colitis (UC) rats. The database and analysis methods were established based on the precise molecular weight of compounds, retention time, neutral loss and reported data, and then the final data were obtained by comparing with the blank control group, combining with the deviation and the cracking rule of the compound. The results showed that the glucoses, hydroxylation and dehydroxylation, methylation and demethylation, dehydrogenation, decarboxylation and hydrolysis of saponin D, B₇ and BD occurred in the plasma and colon tissues of normal and UC model rats. This study will clarify the metabolic transformation of Pulsatilla saponins D, B₇ and BD in rats, determine the prototype components and their metabolites that enter the body, and whether colon injury will affect their metabolism in vivo, so as to explore the possible anti-colitis effective components in the prototype or metabolites of Pulsatilla saponins D, B₇ and BD. This experiment was approved by Animal Ethics Committee of Jiangxi Science and Technology Normal University (approval number: Y202227).

OBJECTIVETo explore the effects of different acupuncture depths of Lianquan (CV 23) for dysphagia after stroke.

METHODSTwo hundred and fifty-one patients with dysphagia after stroke were randomly divided into a deep acupuncture group (group A, 85 cases) a shallow acupuncture group (group B, 83 cases) and a glossopharyngeum acupuncture group (group C, 83 cases). Based on the conventional treatment, the glossopharyngeum acupuncture which was pricking without needles retained at lingual surface, posterior pharyngeal wall of the affected side, Jinjin (EX-HN 12) and Yuye (EX-HN 13) was used in the three groups. After the glossopharyngeum acupuncture, Lianquan (CV 23) was acupunctured 60-70 mm in the group A and 30-40 mm in the group B. The needles were all retained for 30 min. The treatment was applied once a day for 30 days in the three groups. Water swallowing test evaluation scale was observed before and after treatment, and the efficacy was assessed in the three groups.

RESULTSThe total effective rate was 95.3% (81/85) in the group A, which was better than 85.5% (71/83) in the group B and 83.1% (69/83) in the group C (both P < 0.05). The water swallowing test scores were decreased apparently in the three groups (all P < 0.01), and scores in the group A were the most obvious decline (P < 0.01). The decrease of scores in the group A was more remarkable than those in the group B and the group C after two weeks of treatment (both P < 0.05).

CONCLUSIONAcupuncture at Lianquan (CV 23) can effectively improve the dysphagia after stroke. The acupuncture depth can affect efficacy and the effect of deep acupuncture is better.

Objective To evaluate the feasibility of applying spectral CT material suppressed iodine (MSI) imaging as virtual plain CT scan to replace traditional non-contrast (TNC) CT in head and neck neoplasms. Methods A total of 52 patients with initial diagnosis of head and neck neoplasms underwent TNC CT scanning and spectrum mode enhanced scanning in the head and neck with spectral CT. With GSI Volume Viewer software from GE AW4.6 workstation, the enhanced scanning data were processed and MSI images were acquired. The CT values of different tissues (fat, erector spinae, cervical vertebrae, thyroid, and brain parenchyma) and the enhancement rate in erector spinae, carotid sinus were compared between MSI and TNC images. Image quality was objectively evaluated in noise and SNR for MSI and TNC images, while the subjective evaluation included the visibility of lesions, subjective acceptance rate, diagnostic efficacy (with/without lesions or lesion calcification, necrosis). Radiation dose including volume CT dose index (CTDIvol) and effective dose (ED) was compared between MSI and TNC. Results (1) CT values of erector spinae on MSI and TNC imaging were(52 ± 6)and(52 ± 7)HU respectively, and the difference between the two image modes was not significant(t=0.39,P>0.05). CT values on MSI and TNC Imaging were[-74 (-86,-59)HU]and[-79(-73,-61)HU]for fat (Z=-2.71, P<0.05),[139(121,196)HU]and[282 (237,336) HU,Z=-5.46]for vertebrae (Z=-5.46, P<0.05),[57(48,61)HU]and[96(74,110) HU]for thyroid (Z=-4.85, P<0.05),[35(32,39)HU]and[35(32,39)HU]for brain parenchyma (Z=-4.74, P<0.05) respectively. (2) There was no significant difference in enhancement rate of erector spinae between MSI and TNC imaging 1.15(1.07,1.20) and 1.14(1.03,1.26) respectively, Z=-5.50, P>0.05). The difference of carotid sinus enhancement rate was significant 5.75(4.70,6.73) and 4.37(3.91,5.61) respectively, Z=-5.50, P<0.05). (3) The noise of MSI[10.61(8.34,13.57) HU)]was higher than that of TNC [9.32(7.40,11.42) HU](Z=-2.52,P<0.05), and the SNR of MSI [-6.59(-8.59—-4.25)] was lower than that of TNC[-7.94(-10.25,-5.51)] (Z=-2.73,P<0.05). (4) Median scores of subjective imaging quality evaluation were 4(3.00,4.75) and 4(3.00,4.00) in MSI and TNC images respectively, and the difference was not significant(Z=-0.45,P>0.05).Unacceptable and acceptable cases in imaging quality of MSI were 3 and 49 respectively, while those were 2 and 50 in TNC group. Subjective acceptance rate between MST and TNC images was not significantly different(?2=0.01,P>0.05). (5) Diagnostic performance evaluation showed that the consistency of two observers was good in detecting lesions, necrosis and calcification between MSI and TNC image, with K value 0.93, 0.83 and 0.90 respectively (P<0.05). (6) Radiation doses between pure energy spectrum enhanced mode and conventional pre plus post contrast enhanced mode were compared. And differences of CTDIvol[11.78(10.98,17.30) mGy]and[23.89 (22.42, 29.98) mGy] respectively],ED [1.89(1.63,2.29) mSv]and[3.77(3.21,4.16 ) mSv] respectively] were significant(Z=-6.28, P<0.05). Pure energy spectrum enhanced mode reduced 39.07% of CTDIvol and 45.75%of ED respectively. Conclusions MSI imaging can be a potential substitute for TNC imaging. And it has clinical values in the diagnosis of head and neck neoplasms.

Objective To evaluate the discrepancy of parameters generated on dual-energy spectral CT (DECT)imaging in the different pathological grade of laryngeal and hypopharyngeal squamous cell carcinoma (LHSCC),and to provide helpful information of the prognosis and the guide of clinical treatment.Methods 61 patients with pathologically confirmed LHSCC who underwent contrastenhanced DECT before therapy were retrospectively analyzed.The enhanced monochromatic data were analyzed with workstation.Iodine concentration of lesion (IC),water concentration of lesion (WC)and slope of spectral HU curve (s-SHC)were acquired.According to cell differentiation,all patients were divided into well,moderately and poorly differentiated groups.The difference of IC,WC,s-SHC,constituent ratio of T stage were compared among different groups.Results The IC and s-SHC had significant difference among well,moderately and poorly differentiated groups(F =3.56,3.96 respectively,P <0.05).The two-two paired comparisons demonstrated that there were significant difference of IC between poorly and well differentiated group(P <0.05).The others two-two paired comparisons demonstrated no significant difference (P>0.05).There were no significant difference of WC among three groups respectively (H =0.84,P >0.05).χ2 test showed that there was no significant difference for the constituent ratio of T stage among three groups (P >0.05).Conclusion IC and s-SHC can help to judge the pathological grade of LHSCC,and they may be useful to evaluate the prognosis of LHSCC.
