Objective To explore the effect of biological resonance technique in the detection and treatment of milk protein induced allergic diarrhea in infants .Methods A total of 60 infants with protein allergic diarrhea were detected by bio-resonance technique of German -made Bikang Biotherapeutic Instrument .The statistical bio-reso-nance technique was used to detect the distribution of allergy in infantile milk allergic diarrhea and treatment effect . Results Bio-resonance technique for detection of infantile milk protein allergic diarrhea ,the first six allergies were milk,milk protein,fish mixture,normal intestinal flora,mite and breast milk.The total effective rate was 95.00％,the effective rate was 95.83％ in the female group and 94.44％ in the male group,the difference was not statistically significant(χ2 =0.142,P>0.05).There was no significant difference between the 9th and 6th month group(χ2 =0.671,P >0.05).After treatment for 1 month,the follow -up showed no recurrence.Conclusion Resonance technology is one of the best technique to detect and treat allergic diarrhea in infants and young children , which is suitable for clinical use .

Objective To analyze the effect of limited internal fixation contrasting micro -external fixator in the treatment of fractures around the hand.Methods Sixty patients with fractures around the hand treated in the First People′s Hospital of Huizhou from May 2015 to May 2017 were selected and randomly divided into the internal fixation group and the external fixation group,and then were treated with effective internal fixation and mini external fixator respectively.The curative effect,operation condition,postoperative recovery and complications of the two groups were compared.Results The treatment effect(excellent and good rate was 96.67%(29/30)),fracture recovery time((6.37 ± 1.25)weeks),hospitalization time((4.32 ±1.23)d)and postoperative complication rate(10.0%(3/30))in the external fixation group were superior to those in the internal fixation group(76.67%(23/30),(8.87 ± 2.12)weeks,(7.29 ± 2.15)d,33.3%(10/30)),the differences were statistically significant(P=0.032;t=15.459,P=0.005;t=17.788,P =0.001;P=0.012).However,there were no significant differences between the external fixation group and internal fixation group in the operation time and the blood loss during operation((28.41±2.87)min vs.(27.67±1.42)min;(16.87 ± 3.71)ml vs.(16.43 ± 2.89)ml)(t=2.459,P=0.423;t=1.788,P =0.619). Conclusion Compared with limited internal fixation,the mini external fixator is reliable and effective,with less complications,and is more conducive to the early activity and functional recovery of the patients with hand fractures.
