Objective To probe into the clinic effect of folded infusion tube which can produce negative pressure on increasing the success rate of infants' scalp venepuncture. Methods 200 infant patients were divided into the control group and the observation group with 100 cases in each group. The control group used routine venepuncture method, while folded infusion tubes are used in the obser-ration group. The end of infusion tubes were folded by 0.5 cm and clamped well. When the needle has been punctured under an infant patient's scalp, the clamp could be loosed so that there was a little neg-ative pressure in the tube. Then the situation of natural revehent blood and success rate of scalp venepuncture were observed in the two groups. Results Rate of natural revehent blood in the control group was 72%, and success rate of scalp venepuncture was 87%. Rate of natural revehent blood in the observation group was 97%, and success rate of scalp venepuncture was 97%. Rate of natural revehent blood and success rate of scalp venepuncture in the observation group were both higher than those of the control group. Conclusions Folded infusion tube can immediately judge whether the needle is punctured inside the blood vessel and effectively increase the success rate of scalp venepuncture.

Objective To study effects of palm pressing peripherally inserted untral catheter(PICC) and mandible-pressing-on-shoulder on PICC′s misplacement in jugular veins during intubation. Methods Seventy-six patients undergoing intubation with PICC were randomized into observation group and control group equally by random digital table. The palm pressing PICC method was used in the observation group and the mandible-pressing-on-shoulder method was used in the control group. The two groups were compared in terms of the incidence of PICC misplacement. Result The misplacement rate of PICC in the experiment group was significantly lower than that in control group (P<0.01). Conclusion Palm pressing method is much effective in prevention of PICC misplacement in jugular veins and worth promoting especially in hospitals of basic level.

Objective To explore the distribution of syndromes and the characteristics of damp-induced disease in patients with multiple sclerosis in Lingnan area,and to improve the reference for TCM treatment of MS patients.Methods A retrospective analysis of the general information of 268 patients with multiple sclerosis (MS) admitted to our hospital from March 2015 to 2016 was conducted.And the information on four diagnoses of Chinese medicine,including the main manifestations,tongue pulse,frequency were for the cluster analysis.The Multivariate logistic regression analysis was used to analyze the factors influencing MS syndromes.The distribution and dynamic changes of the symptoms of the patients at the initial diagnosis,4 weeks after treatment and 8 weeks after treatment were observed,and the dynamic changes of the syndrome form were analyzed.Results In the course of the development of MS patients,the sigle syndrome and 6 syndromes can appear simultaneously.Among them,there were syndrome of the wind,wet,phlegm,heat and blood stasis.At the 4 and 8 weeks after treatment,2nd syndromes gradually increased,but the 3rd syndromes and 4th syndromes remain unchanged,and the 5th syndrome significantly decreased.The syndrome is complicated and changeable from the side of the development process.The results of multi factor Logistic regression analysis showed that purple tongue was an important factor of blood stasis [OR (95％ CI)=2.357(1.996-3.017)],and the yellow greasy coating was an important factor of hot dampness [OR (95％ CI)=3.654(3.125-4.876)],and the thin and weak pulse was the important factor of the deficiency of liver and kidney[OR (95％ CI)=3.983(2.349-4.218)];deficiency pulse was an important factor affecting Qi and blood deficiency syndrome[OR (95％ CI)=2.852(2.068-3.192)];limb twitching was an important factor affecting kidney yang deficiency syndrome [OR (95％ CI)=3.850(1.037-16.524)],and the above data were statistically significant (P＜0.05).For patients with damp heat attacking vesselssyndrome,the most frequent clinical symptoms were the spinal sensory disorders,cranial nerve disorders and cerebellar symptoms,emotional disorders and mental disorders,consciousness disorders and epilepsy,two bowel movements and weakness.Conclusions The wind,wet,phlegm,heat and blood stasis of the MS patients in south of the Five Ridges gradually increase.With the treatment,the syndrome combination was gradually simplified,the essential contradiction gradually revealed,the single syndrome gradually merged,the 2 syndrome gradually increased,the 3 syndrome and the 4 syndrome remained constant.
