ObjectiveTo observe the curative effect of galvanoiontophoresis combined with ultrashort wave therapy on cervical vertebrae disease-derived arrhythmia.Methods112 patients with cervical vertebrae disease-derived arrhythmia were randomly divided into the treatment group and control group with 56 cases in each group. All patients of two groups were treated with antiarrhythmia drug, Sibelium and traditional Chinese medicine. While, the patients of the treatment group were added with galvanoiontophoresis combined with ultrashort wave therapy to eliminate the aseptic inflammation.ResultsThe cure rate and total effective rate of the treatment group were 51.8% and 94.6%. Those of the control group were 16.1% and 76.8%. The effect of the treatment group was better than that of the control group significantly ( P<0.01).ConclusionThe galvanoiontophoresis combined with ultrashort wave therapy has a better effect on cervical vertebrae disease-derived arrhythmia.

Objective To diagnose a rare variant Hb Shaare Zedek in a Chinese family,and describe its clinical feature.Methods Blood samples of seven members of three generation were collected.Standard blood routine analysis,hemoglobin electrophoresis and blood gas analysis were used for phenotype analysis.Gap-PCR and reverse dot blot analysis were used to detect common thalassemia mutations.DNA sequence analysis of the human α and β globin genes were used to identify the mutation site of these samples.Results The result of blood routine analysis was normal in the proband,but a abnormal hemoglobin band (22.4％,capillary assay) was found by hemoglobin electrophoresis.In the blood gas analysis,the partial pressure of oxygen and blood oxygen saturation were 72.0 mm Hg ( 1 mm Hg =0.133 kPa) and 93.0％ in the proband.The heterozygous mutations in αl globin gene at codon 56 ( AAG ＞ GAG)which leaded Glu substitution to Lys were identified in the proband.Other family members who carried the same mutation showed similar phenotype,with abnormal hemoglobin band ( 22.4％ - 23.9％,capillary assay),low partial pressure of oxygen (59.0 - 72.0 mm Hg) and blood oxygen saturation (91.0％ -93.0％).Conclusions The heterozygote of Hb Shaare Zedek leads to slight symptoms with abnormal hemoglobin band,decreased partial pressure of oxygen and blood oxygen saturation.Discovery of this mutation enriches the abnormal hemoglobin spetrum of Chinese people,and it is useful for the clinical diagnosis and genetic counseling of hemoglobinopathies.

In order to prepare and apply the polyvinyl alcohol/drug-loaded chitosan microspheres composite wound dressing, we first prepared chitosan microspheres by emulsion cross-linking method, and then added chitosan microspheres into the reactants during the acetalization of polyvinyl alcohol and formaldehyde. We further studied the morphology, water absorption, swelling degree, mechanical properties and in vitro release of the sponge with different amount of chitosan microspheres. The results showed that polyvinyl alcohol/drug-loaded chitosan composite sponge has porous structure with connectionism. Increasing the amount of chitosan microspheres would make the apertures smaller, so that the water absorption and the swelling of sponge decreased, but the tensile strength and compressive strength increased. With the increase of the amount of chitosan microspheres, the drug absorption of cefradine and the release rate increase, and the release time become longer. With the results of toxicity grade of 0 to 1, this type of composite sponge is non-toxic and meets the requirement of biocompatibility. The observation of rabbit nasal cavity after surgical operation suggested that polyvinyl acetal sponge modified with the chitosan has antiphlogistic, hemostatic and non-adherent characteristic, and can promote the healing and recovering of the nasalmucosa. After using this composite material, best growing surroundings for patients' granulation tissue were provided. Exposed bone and tendon were covered well with granulation tissue.
