Objective To describe the lived experience of mothers of children with hydrocephalus. Methods A semi-structured interview was conducted with 14 mothers of children with hydrocephalus. Data were analyzed based on Colaizzi phenomenotogical research method. Results Through the analysis, sorting and refining the theme, the mother's care experience could be divided into three themes: psychological emotional, stress response, social support requirements. Conclusions Nursing staff should have a thorough understanding of the experience to provide medical care and emotional support, improve the ability of the parents care,which could help caregiver adapt to their roles, maintain and promote the health of children patients and their families .

ObjectiveTo investigate the clinical features and nursing care of neuralgic amyotrophy.MethodsThe course of the treatment and nursing in a group of patients with idiopathic neuralgic amyotrophy was analyzed retrospectively.ResultsMyoatrophy was found in all patients, while 42% of patients were involved in both sides. Serious pain, as initial symptom, was found in 92% of patients. After medical and physical treatment, as well as holistic nursing care, the pain disappeared in 1～2 weeks in all patients but one. All patients had been followed up for 2～13 months, muscle power was recovered in 67% of all patients, partially recovered in 33% of patients.ConclusionThe careful nursing and observation is very helpful for recover of neuralgic amyotrophy and can decrease complications.

RESULTS:The MIC for Uu that both azithromycin sustained-release vaginal suppository and azithromycin dried suspension is lower than 0.125?g?mL~(-1).CONCLUSION:Azithromycin sustained release vaginal suppository has significant inhibitive effects on Uu under the experiment condition.

A simple colorimetric method for detection of isocarbophos was developed based on the enhanced peroxidase-like activity of hemin. Hemin could catalyze the oxidation of peroxidase substrate 3,3′,5,5′-tetramethylbenzidine (TMB) by H2O2, which made TMB to lose one electron and caused reaction solution color changing from initial transparent to blue-green. Adding isocarbophos improved hemin affinity to substrates, which further enhanced peroxidase-like activity of hemin and made TMB to lose two electrons. The color of TMB solution was further changed from blue-green to yellow, and the degree of color change was proportional to the concentration of isocarbophos. Under the optimal conditions, the present analytical method for isocarbophos detection had a dynamic range from 2 μg/L to 100 μg/L with a detection limit of 1.2 μg/L (3σ). The selectivity assay demonstrated that other organophosphorus pesticides exhibited negligible interferences for isocarbophos detection. The application of the proposed method in the practical samples showed that the mean recovery of isocarbophos was in the range of 94.4％-113.0％, thus it could be widely applied to rapidly and sensitively detect isocarbophos in the agricultural products.

AIM:To investigate the expression of GAP-43 mRNA and protein of the motor neurons in spinal cord following the brachial plexus avulsion injury.METHODS: In the present study,three kinds of models of brachial plexus avulsion injury were made: right C7 anterior root avulsion(group A),C7 anterior root avulsion with right C5-T1 posterior roots breaking(group B),right C7 anterior root avulsion with hemi-transect between C5 and C6 segment of spinal cord(group C).The expression of GAP-43 mRNA in anterior horn of spinal cord was detected at 14 days after operation by SYBR green quantification RT-PCR technique.The amounts of GAP-43 positive neurons in spinal cord were detected at 1,3,7 and 14 days after operation by immunohistochemistry technique.RESULTS: In control group,the expression of GAP-43 mRNA was very low in anterior horn.By 14 days after operation,the expression of GAP-43 mRNA was evidently up-regulated compared with control group.GAP-43 positive neuron was observed in control group at 1st day and 3rd day after operation.GAP-43 positive neurons appeared at 7th day and peaked at 14th day after operation.The expression of GAP-43 mRNA and protein were maximum in group C,group B was the lowest.CONCLUSION: The expression of GAP-43 mRNA and GAP-43 protein were up-regulated following brachial plexus injury.The expression of GAP-43 protein results from the recombination of proteins.GAP-43 is closely related to the axon regeneration and functional reconstruction.

Objective To observe the characteristics of liver-kidney yin deficiency syndrome in late stage of spontaneously hypertension rats (SHRs). Methods Ten 12-month-old healthy male SHRs were put into syndrome observer group (SHR group), while ten male WKY rats with the same age were set as control group (WKY group). Syndrome differentiation method on rats was employed to transform the four-diagnostic information into general behavior indexes with the same significance. The afternoon anal temperature, tongue color, holding power, ability of learning and memory, serum estradiol and testosterone level were observed, compared and analyzed. Results Compared with the WKY group, rats in the SHR group had higher afternoon anal temperature, redder tongues, poorer strength and claw holding power and their ability of learning and memory was retarded; the level of serum estradiol was lower;the ratio of estradiol to testosterone was higher. All of these were largely in line with deficiency of live-kidney yin syndrome. Conclusion SHRs in late stage show characteristics of liver-kidney yin deficiency syndrome.

OBJECTIVETo study the influence of aconite root, a Chinese medicinal herb with hot property, on energy metabolism and gene expression spectrum, and to analyze the possible mechanism of it effect.

METHODThirty two SPF Wistar rats were randomly divided into aconite root group and control group. Decoction of aconite root and NS were intragastrically administrated with the concentration of 10 mL x kg(-1) respectively once a day for 20 days. Temperature, energy intake (EI), digestive energy (DE) and metabolic energy (ME) were measured. The activity of ATPase and succinate dehydrogenase (SDH) in liver was detected by colorimetry. The gene expression of liver was detected with Illumina's rat ref-12 gene array. The differential expression genes were selected, annotated and classified based on gene ontology (GO). Real-time quantitative reverse-transcriptase PCR (Q-RT-PCR) was used to test the accuracy of the array results.

RESULTCompared with the control group, the toe temperature (TT) on the 10th and 20th day after the administration,the EI/BM( body mass), DE/BM, ME/BM and the activity of Na+ - K+ - ATPase, Ca2+ - Mg2+ - ATPase and SDH of liver in the aconite root group increased significantly (P<0.05). There were 592 differential expression genes in aconite root group compared with the control group. Based on Go analysis, the most significant genes was related to metabolic process (lgP = - 15.5897).

CONCLUSIONAconite root could improve the energy metabolism in rats, by influencing the metabolic process of sugar, lipid and amino acid, which may be the main molecular mechanism of warming yang and dispelling cold for the treatment of the cold syndrome according to Chinese medicine theory.
