Objective To develop an approach for a rapid extraction of genomic DNA fragments from serum.Methods Serum specimen from human was processed using high temperature denaturation and was centrifuged, then using various primer sets to amplify the DNA fragment extracted, so as to verify the efficiency of this DNA extraction method.Results The templates preparing from this DNA extraction method were able to guarantee the amplification of fragments shorter than 400 base pairs.Conclusion This method is simple, rapid and inexpensive.These genomic DNA fragment extracted can be utilized to amplify definite DNA template for polymerase chain reaction.

A digital beamformer in medical ultrasound imaging systems conventionally requires that the returning signals received by transducers are sampled at a rate significantly higher than the Nyquist rate. This paper presents a digital beamformer that employs zero padding followed by digital interpolation filtering to achieve vernier beamformer delays. The experimental results show that the digital interpolation beamformer can greatly decrease the complexity of A/D converter circuitry.

Objective To evaluate the therapeutic effect of acupoint catgut embedding on gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury.Methods Sixty-eight consecutively hospitalized patients with gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury admitted to the Department of Intensive Care Unit (ICU) in the First Affiliated Hospital of Zhejiang University of Chinese Medicine from January 2015 to December 2015 were enrolled.Six of those patients were withdrawn from the course of observation,and actually only 62 patients entered the study.They were divided into an observation group (32 cases) and a control group (30 cases) by random number table.All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days.The observation group was additionally treated with acupoint catgut embedding.The control group took mosapride tablets via a nasogastric tube 5 mg,3 times a day.Intra-abdominal pressure (IAP),gastric residual volume (GRV),time for reaching standard enteral nutrition,serum diamine oxidase(DAO),D-Lactate activity,incidence of hospital-acquired pneumonia (HAP),hospitalization days in ICU,28-day mortality and adverse reactions of acupoint catgut embedding were observed in the two groups.Results After treatment,the levels of IAP,DAO,D-lactic acid were lower than those before treatment,GRV was less than that before treatment in the two groups,and after treatment for 7 days the changes were more significant in the observation group [IAP (cmH2O,1 cmH2O =0.098 kPa):12.42±3.11 vs.17.70 ± 2.98,GRV (mL):129.54 ± 57.54 vs.242.91 ± 99.29,DAO (U/L):9.06± 2.84 vs.13.60 ± 7.16,D-Lactate (mg/L):16.47 ± 5.39 vs.26.29 ± 9.62,all P < 0.01].Days of mechanical ventilation (days:6.97 ± 4.13 vs.9.23 ± 4.61),time for reaching standard enteral nutrition (days:4.25 ± 3.15 vs.5.50 ± 3.12) and hospitalization days in ICU (days:9.50± 4.03 vs.12.20 ± 6.38) in observation group were significantly shorter than those in control group (all P < 0.05).The incidence of HAP [15.6% (5/32) vs.40.0% (12/30)] and 28-day mortality [3.1% (1/32) vs.6.7% (2/30)] in observation group were obviously lower than those in control group.The patients in observation group had no significant adverse reactions of acupoint catgut embedding.Conclusions Acupoint catgut embedding therapy is not only easy to operate,but also can effectively improve gastrointestinal motility and intestinal barrier function in patients with gastrointestinal dysfunction after surgery of severe head injury,thus it is beneficial to reaching the enteral nutritional goal in less time,reducing the incidence of HAP,shortening the hospitalization time in ICU and promoting the recovery of the patients.

ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.
