OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

Immunohistochemical technique was an essential tool of conventional diagnosis,therefore,the application of immunohisto- chemistry in reformation of pathology laboratory teaching would boost pathological experimental teaching standards to a higher level.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.

OBJECTIVE: To investigate the effect of electrical stimulation with bilateral scalp acupuncture on time parameters in video fluoroscopic swallowing study and cortical excitability in patients with dysphagia after cortical stroke, as well as its possible mechanism of action. METHODS: A total of 84 patients with dysphagia after cortical stroke were randomly divided into control group with 41 patients and observation group with 43 patients. The patients in the control group were given acupuncture based on acupoint selection for pseudobulbar palsy, and in addition to the treatment in the control group, the patients in the observation group were given electrical stimulation of bilateral scalp acupuncture, with acupuncture and pulse acupuncture at the lower 2/5 of the bilateral anterior oblique parietotemporal lines[on the line connecting Qianshencong (EX-HN1) to Xuanli (GB6)] and the lower 2/5 of the bilateral posterior oblique parietotemporal lines [on the line connecting Baihui (GV20)and Qubin (GB7)], with a needle retaining time of 30 minutes, once a day and 6 times a week for 3 weeks. Before treatment and after 3 weeks of treatment, oral delay time (ODT), oral transit time (OTT), pharyngeal delay time (PDT), and pharyngeal transit time (PTT) were compared between the two group; the Rosenbek Penetration-Aspiration Scale was used to evaluate penetration-aspiration and appro-ximate entropy (ApEn) of EEG nonlinear index. RESULTS: After treatment, both groups had significant reductions in ODT, OTT, PDT, PTT, and Rosenbek Penetration-Aspiration score and a significant increase in ApEn (P<0.05). Compared with the control group after treatment, the observation group had significant reductions in ODT and OTT (P<0.05) and significant increases in the ApEn values of bilateral central, parietal, and posterior temporal regions (P<0.05), while there were no significant differences in PDT, PTT, and Rosenbek Penetration-Aspiration score between the two groups (P>0.05). CONCLUSION: In addition to body acupuncture, electrical stimulation with bilateral scalp acupuncture can improve ODT and OTT in the treatment of patients with dysphagia after cortical stroke, which may be associated with the increased excitability of the swallowing cortex.

Activation of acid-sensing ion channels (ASICs) plays an important role in neuroinflammation.Macrophage recruitment to the sites of inflammation is an essential step in host defense.ASIC 1 and ASIC3 have been reported to mediate the endocytosis and maturation of bone marrow derived macrophages.However,the expression and inflammation-related functions of ASICs in RAW 264.7 cells,another common macrophage,are still elusive.In the present study,we first demonstrated the presence of ASIC 1,ASIC2a and ASIC3 in RAW 264.7 macrophage cell line by using reverse transcriptase polymerase chain reaction (RT-PCR),Western blotting and immunofluorescence experiments.The non-specific ASICs inhibitor amiloride and specific homomeric ASIC 1 a blocker PcTx 1 reduced the production of iNOS and COX-2 by LPS-induced activating RAW 264.7 cells.Furthermore,not only amiloride but also PcTx 1 inhibited the migration and LPS-induced apoptosis of RAW 264.7 cells.Taken together,our findings suggest that ASICs promote the inflammatory response and apoptosis of RAW 264.7 cells,and ASICs may serve as a potential novel target for immunological disease therapy.

Objective To investigate the serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF in gas-tric cancer.Methods The serum levels of CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were detected in 46 healthy con-trols,45 atrophic gastritis patients and 39 gastric cancer patients.Serum levels of CEA,CA724 were measured by ELC meth-od,PGⅠ,PGⅡ by time resolved fluorescence immunoassay (TRFIA)and SF by immunoturbidimetry(ITM).Results ①Compared to the healthy controls,the statistical contrast of serum levels of CEA,CA724,PGⅠ,PGⅡ and PGI/PGII except SF was significant in gastric cancer patients(P<0.05),only PGⅠ,PGⅡ,SF had significant difference in atrophic gastritis patients (P<0.05).Compared to atrophic gastritis patients,the serum levels of CEA,CA724 were significantly higher,but PGⅠwas lower in gastric cancer patients(P<0.05).②When CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were used to di-agnose gastric cancer individually,the sequence of the area under ROC curve was CEA,SF,CA724,PGI/PGII,PGⅡ and PGⅠ.Only the areas of PGⅠ,PGⅡunder ROC curve had significant statistical difference (P<0.05).③The sensitivity,speci-ficity,PPV and NPV were different when these indexes were used to diagnize gastric cancer individually or incorporatedly. Conclusion The serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF had important reference value for the diagnosis of gastric cancer although the diagnostic value was different individually or incorporatedly;the content of serum PG and the ratio of PGI/PGII were closely related to the gastric mucosa.

In 2013, the World Health Organization reported the first case of human infection with a new influenza A (H7N9) virus in China. This has caused damage and panic within certain areas in China. Therefore, analysis of this virus with bioinformatics technology is very necessary. Neuraminidase (NA) is one of the most important antigens of the influenza virus and an important target for anti-flu drugs. In this study, the nucleotide and protein sequences of NA gene of A/H7N9 influenza viruses were retrieved from the NCBI database, and MEGA 5.0 software was employed to construct a phylogenetic tree based on the nucleotide coding sequence; BioEdit software was used to align the nucleotide and protein sequences of NA and calculate the homologies of nucleotides and amino acids and then to analyze the important mutation sites of NA gene. The results demonstrated that the spread of influenza virus H7N9 showed certain geographical and temporal relations. The H7N9 virus isolated from China in 2013 belonged to Euroasiatic serotype, and its NA stalk region hadobvious variation, which may be one of the reasons that this virus infects human. These analyses may be very helpful for understanding the evolutionary relationship and mutation trend of A/H7N9 influenza viruses.
