Objective To observe the effect of acupuncture plus rehabilitation on the development quotient in patients with mental retardation (MR) and its therapeutic efficacy by using the Neural and Mental Development Check List for Children Aged 0-6. Method Sixty MR patients were divided into a treatment group and a control group by the random number table, 30 cases in each group. The treatment group was intervened by acupuncture plus rehabilitation training, while the control group was by rehabilitation alone. The improvement of development quotient and therapeutic efficacy were evaluated after 3 treatment courses. Result The improvement of development quotient in the treatment group was more significant than that in the control group; the total effective rate was 83.3% in the treatment group versus 73.3% in the control group, and the difference was statistically significant (P<0.05). Conclusion Acupuncture plus rehabilitation training can produce a more significant efficacy than rehabilitation alone in treating MR.

Objective To investigate the effects of glutamine(Gln) and epidermal growth factor(EGF) on small intestinal repair in neonatal rats with necrotizing enterocolitis(NEC).Methods Forty neonatal rats of NEC model were divided into 5 groups:group A(control group),group B(NEC model),group C(NEC+Gln),group D(NEC+EGF+Gln).After NEC model of neonatal rats,all the neonatal rats were returned to their mothers.In the 4~(th) day,all the subjects were put to the death.Intestinal tissue located at the boundary of ileum and cecum was obtained to observe histological changes.Morphological changes were measured under a light microscope,and expression of proliferating cell nuclear antigen(PCNA) as an index of cell proliferation was observed using immunohistochemical staining and image analysis,expression of apoptosis was observed by TUNEL staining and image analysis.Results In group B,the histological lesions ranged was different,and was graded 3 score.In group C,D,the histological lesions ranged was graded 1 score.The number of(PCNA) in group B was lower than that in group A(P

BACKGROUND:Local injection with simvastatin can induce osteogenesis, significantly increase the bone mineral density and mechanical strength of femoral neck and femoral condyle of rats with osteoporosis and analyze effects of local injection of simvastatin on trabecular bone of the femoral condyle.
OBJECTIVE:To explore the effects of local injection of simvastatin on trabecular bone of the femoral condyle of osteoporotic rats and provide experimental basis for the application of simvastatin in clinical topical treatment of osteoporosis.
METHODS:Eighteen female Sprague-Dawley rats received bilateral ovariotomy at 3 months, and were used to produce rat models of osteoporosis. They were assigned into three groups. Experimental rats received 5 and 10 mg simvastatin by single injection into right femoral cavity. Control rats received blank vector. The rat models were sacrificed at 1 month after injection and specimens were col ected. Right femoral condyles were taken out for bone histomorphometric analysis by Micro-CT.
RESULTS AND CONCLUSION:One month post-injection, Micro-CT scanning results revealed that cortical bone thickness, trabecular bone density and connection rate were significantly better in the simvastatin group than those in the control group. Results indicated that single injection of smal-dose simvastatin obviously promoted rebuilding of trabecular bone of condyles of femur, improved microstructure of skeleton, strengthened local skeleton, prevented and treated osteoporosis, and provided a further basis for the prevention and treatment of osteoporosis, especial y for osteoporotic fractures.

Objective To know the condition of cognition of cardiac surgical patients for patient safety.Methods Carried out a semi-structured depth interviews among 8 cardiac surgical patients,and then cleared up the information by phenomenology method.Results Three themes were extracted:patients' consciousness about patient safety,the lack of knowledge of patients in patient safety management,the lack of emotional support of patients in patient safety.Conclusions Some positive counter-measures should be taken by nursing administrators to resolve patients' difficulty and confusion,and then promote patients take part in the course of safety management of patients,ensure patients' safety.

Objective To investigate the effects of Cilazapril and Valsartan on atrial structural and functional remodeling and its mechanism in atrial fibrillation(AF)dogs induced by chronic rapid atrial pacing.Methods Twenty-seven AF dog models were built by the First Affiliated Hospital of Harbin Medical University from Mar.2006 to Oct.2006.The experimental dogs were randomly divided into sham-operated group(n=6),control group(n=7),Cilazapril group(n=7)and Valsartan group(n=7).The dogs in control group,Cilazapril group and Valsartan group were paced at 400 bpm for 6 weeks.The dogs in Cilazapril and Valsartan group received Cilazapril(1 mg?kg-1?d-1)and Valsartan(30 mg?kg-1?d-1)1 week before rapid atrial pacing until pacing stop respectively.Transthoracic and transoesophageal echocardiographic examinations were performed to detect changes in structure and function of left atrium and left atrial appendage,before and after 6-week rapid atrial pacing.Atrial collagen volume fraction(CVF)was analyzed by Masson staining.The expression of ERK1 and ERK2 in the atrial tissue were tested by immunohistochemistry.TUNEL technique was used to detect the atrial cell apoptosis.Results (1)Compared with the control group,the LA and LAA volumes were significantly smaller,LAEF,LAAEF,V-LAA+ and V-LAA-were dramaticaly higher in the Cilazapril group and the Valsartan group after 6-week rapid atrial pacing.(2)Compared with the control group,the incidence of apoptosis,CVF and the expression of atrial ERK1 and ERK2 decreased dramatically in the Cilazapril group and the Valsartan group.Conclusion Cilazapril and Valsartan could prevent atrial fibrosis and cell apoptosis in the atrial fibrillation dogs induced by chronic rapid atrial pacing.

OBJECTIVE To reduce or avoid the risk factors of idiopathic sudden hearing loss in Qinghai. METHODS The clinical data of 143 sudden hearing loss patients was analyzed in Qinghai by the questionnaire. RESULTS The high incidence of sudden hearing loss happened at 2 to 6 hours after waking up in the morning. And most of the patients occurred at 18～50 years old(accounted 70.63%). 79.65% of the patients were mental laborers, 57.34% were drinkers, and 59.44% were very tired before illness. There were significant differences(P

Objective To compare the propagation speed and physical parameters between underwater blast wave and air blast wave. Methods The physical parameters of blast wave were measured by PCB pressure transducers (USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed. Results Underwater blast wave was characterized by high propagation speed, high peak overpressure value, great impulse, however, short duration. Compared with air blast wave, the propagation speed of underwater blast wave was 3.70-4.30 times higher than that of air blast wave, the peak overpressure value was 227.15-247.86 times higher, and the impulse was 8.48-11.80 times greater than that of air blast wave. Conclusion Underwater blast wave propagates faster than that air blast wave. Meanwhile, it also peoduces higher peak overpressure value and impulse. This result is helpful for the evaluation of injury severity and treatment of underwater blast injury.

Surfactants are employed widely in household and industryial products wordwide.Everyday millions pounds surfactants and their products are dispersed into soil, water, food and human body that posing a threat to human health. The paper expatiated on the topic that the threats of surfactants on food safety with arguments as: acute toxicity, genetic toxicity, estrogenic effects, bioconcentrate and so on. At last, the article emphasized it is essential to have comprehensive study on the surfactants toxicity and influence on food safety.
