ObjectiveTo observe the effect of the scalp acupunction on children with cerebral palsy.Methods56 cases with cerebral palsy were divided into two groups: the treating group(scalp acupuncture and modern rehabilitation) and the control group(modern rehabilitation only) with 28 cases each. The ADL and the motion function were compared. ResultsThere is a significant defference between the two groups on the ADL, while no significant defference was observed on motor function between the two groups.Conclusions Scalp acupuncture is effective on improvment of ADL of the children with cerebral palsy.

OBJECTIVE To investigate the cognition on hand hygiene and the reasons affecting the hand hygiene performance in hospital.METHODS Medical staff of 358 parsons were randomly selected by questionnaire.RESULTS It was higher cognition among medical staff on hand washing indication learned from Standards of Hand Hygiene among Medical Personnel in Medical Institutions(draft for soliciting opinions) issued by the Ministry of Health.The cognition coincidence of hand sterilization indication was 68.04%,but existed some less cognition or miscognition in this field among them.The main factors affecting the hand hygiene performance were busy at work,to which was the primary cause to affect use of stream water to wash hands.The concept that using stream water wash hand is reliable is the primary cause influence medical staffs to use alcohol scrape hand.CONCLUSIONS The nosocomial infection monitoring,guidance and control should be emphasized in the field of more use of the fast hand antiseptics instead washing hands and supervising the relevance of the amount of hand hygiene product consumpsion to nosocomial infections.

Alzheimers disease (AD) is a progressively and retrogressively neurodegenerative disorder of central nervous system severely threatening the aged. The studies of animal models, which share the very similar neuropathological characteristics with human, provide tools for the understanding of the etiology, mechanisms and medicine screening of AD. The distribution and chemical composition of amyloid-beta (A- beta) peptide -positive deposits were investigated in various non-human primate models. Various proportions of A- beta deposits contained cholinesterase activities, apolipoprotein E(ApoE) and alpha1-antichymotrypsin immunoreactivity. Alterations in the basal forebrain cholinergic system have been widely studied, but the magnitude of decline and relationship to cognitive impairment are still a matter of debate. This article also includes the latest research of the changing on tau, subtle structural alterations in axons, and neurofibrillary tangles (NFT) in the brain tissues of the non-human primate models.

BACKGROUND: The reaction of osteoblasts is important role in the reconstruction of osteocytes, and the mechanism of bone remodeling can be known from the cytological level through analyzing the mechanical reaction of osteoblasts under different loading.OBJECTIVE: To analyze the effects of low frequency vibration on the proliferation and differentiation as well as the matrix excretion of cultured human osteoblasts.DESIGN: A comparative observation.SETTING: Department of Orthopaedics, Nanfang Hospital of Southern Medical University.MATERIALS: The experiment was carried out in the laboratory of Nanfang Hospital from January to December in 2002. Human osteoblasts were isolated from the iliac cancellous bone of adults.METHODS: The osteoblasts were cultured for 48 hours, and then treated with low frequency vibration of 0.1, 0.2, 0.5, 2 and 5 Hz. The proliferation of the osteoblasts was detected with flow cytometry, and the activity of alkaline phosphatase (ALP) and content of osteocalcin were assayed by spectrophotometric methods and radioimmunoassay respectively.MAIN OUTCOME MEASURES: ① Effects of low frequency vibration on the ALP activity and osteocalcin excretion of osteoblasts; ② Effects of low frequency vibration on the proliferation of osteoblasts detected with flow cytometry.RESULTS: ① 0.2 and 0.5 Hz vibrations could markedly increase the ALP activity of osteoblast (P ＜ 0.01), but that of 5 Hz obviously decreased the ALP activity (P ＜ 0.01). 0.1 and 2 Hz vibrations had no obvious effects on the ALP activity of osteoblasts. ② 0.2 and 0.5 Hz vibration could significantly increase number of osteoblasts at S phase from 10.4% to 12.45% and 16.12%, and the proliferative index increased from 20.14% to 26.21% and 28.75%; 0.1 and 2 Hz vibration has not obvious effects in osteoblast proliferation index; 5 Hz vibration obviously decreased the proliferative index value to 13.22% (P ＜ 0.05). 0.1 and 2 Hz vibrations had no obvious effects on the proliferative index of osteoblasts (P ＞ 0.05). ③ 0.2 and 0.5 Hz vibrations could obviously increase the amount of osteocalcin excretion to 1.87 μg/L and 2.47 μg/L(P ＜ 0.05), but 2 and 5 Hz vibrations decrease the amount of osteocalcin excretion (P ＜ 0.05), and that of 0.1 Hz had no obvious effect on amount of osteocalcin excretion (P ＞ 0.05).CONCLUSION: Low frequency vibrations of 0.2-0.5 Hz could accelerate the proliferation and differentiation as well as the excretions of active materials of osteoblasts, and it plays an instructive role for low frequency vibration to treat fracture.

0.05). The titrimetric determination of standard solution containing different levels of chloride showed recovery rates of 98.0%～103.7%, relative standard deviation was 0.16%. Conclusion Automatic potentiometric titration was easy to grasp, rapid and accurate, which was a new analytical method worthy to be applied extensively.

Objective To investigate the effect of cytochrome P_ 450 2A6 (CYP2A6) genetic polymorphisms on serum concentration of sodium valproate. Methods A total of 98 epileptic patients receiving sodium valproate after a period of more than 5 half-time were recruited. The genotypes of CYP2A6 of the patients were detected by nested-primer polymerase chain reaction (PCR) to examine the alleles CYP2A6*1 and CYP2A6*4. Fluorescence polarization immunoassay (FPIA) was used to measure the serum concentration of sodium valproate. Results Of the 98 cases, 73 (74.5%) were wild genotypes, 24 (24.5%) were CYP2A6*1/*4 genotypes and 1(1.0%) was CYP2A6*4/*4 genotype. According to the genotypes of CYP2A6 the patients were divided into two groups,one was group A (CYP2A6*1/*1) and the other was group B (CYP2A6*1/*4 or *4/*4). The mean value of the serum concentration of sodium valproate of the patients in group A(4.1393?0.2793) was higher than that in group B(3.3486?0.3919) with a statistical significance (P

Objective To develop a rapid determination method of nitrate-N in water.Methods In concentrated sulfuric acid,2-isopropyl-5-methyphenol reacts on nitrate and produces the nitro-compound which may turn into the yellow compound in the alkaline solution for the moleculars rearrange.The content of nitrate-N in water can be calculated according to the absorption value at the wave length of 415 nm.Results A good linear relation was found between the concentrations of nitrate-N and the absorption values in the range of 0-15.0 mg/L.The lowest determination concentration was 0.25 mg/L,the recovery rates were 96%-108% and RSD was 1.6%-4.0%.The results were consistent with those determined by UV spectrophotometry.Conclusion The method was simple,sensitive,rapid and accurate.

Objective To investigate clinical and pathological characteristics of acquired digital fibrokeratoma (ADF).Methods Clinical data were collected from 12 patients with ADF,and their clinical manifestations,histopathological features,treatment and prognosis were analyzed retrospectively.Results The mean age at onset of ADF was 39.75 ± 17.69 years (range,17-64.5 years),and the average disease duration was 4.83 ± 5.77 years (range,0.5-20 years).The ratio of male to female was 1.4:1.Most skin.lesions were polymorphic,and mainly involved fingers,toes and nail grooves.Sometimes non-extremity sites are also involved.Histopathological examination of skin lesions showed epidermal hyperkeratosis,acanthosis and broadened dendroid rete ridges.The dermis consisted of mature collagen bundles,fibroblasts and a large number of dilated capillaries.The characteristic manifestation was that most collagen bundles were vertical to the epidermis.Conclusions ADF,a rare benign fibrous tumor with unknown etiology,usually occurs in adults as a solitary lesion on fingers or toes,sometimes in non-extremity sites.Surgery and laser therapy are common treatments for ADF with low recurrence rate.
