Objective To investigate the correlation between family cohesion and adaptability and quality of life in patients with enterostomy. Methods Using Chinese version of Family Adaptability and Cohesion Scale (FACESⅡ-CV) and Chinese version of Stoma-Quality of Life (STOMA-QOL-C) to investigate the status of family cohesion and adaptability, family type and their impact on quality of life of 110 patients with enterostomy. Results Scores of family cohesion and adaptability averaged 59.15 ± 11.94, 47.32 ± 9.40,were significantly lower than 63.90 ± 8.00 and 50.90 ± 6.20 in the norm,and the difference was statistically significant (t=-4.171,-3.990, P<0.01).The family cohesion was positively correlated with the score of quality of life, social interaction and psychological burden(r=0.274, 0.284, 0.263, P<0.05), and the family adaptability was positively correlated with the score of quality of life,social interaction and psychological burden(r=0.316, 0.338, 0.228, P<0.05 or 0.01). The balance type family was 30 cases;scores of quality of life averaged 45.10±7.26, the intermediate type family was 50 cases;scores of quality of life averaged 43.48±9.98, the extreme type family was 28 cases;scores of quality of life averaged 43.37 ± 16.68, and difference between the three was no statistically significant(F=0.442, P=0.665). Conclusions In the nursing process of patients with enterostomy, health care workers should pay attention to improve family cohesion and adaptability, as to achieve the purpose of improving the quality of life of the patients.

AIMTo investigate the role of tumor suppressor PTEN in cardiac hypertrophy, the expression of PTEN mRNA in left ventricle of abdominal aorta constricted-induced cardiac hypertrophic rats which treated with and without captopril was analyzed.

METHODSSD rats were divided into control group, hypertrophy group and captopril group. The expression of PTEN mRNA in left ventricle was detected by RT-PCR in different groups in 4 weeks after operation.

RESULTS(1) Compared with control group, the expression of PTEN mRNA in left ventricle of hypertrophy group was reduced. (2) Compared with hypertrophy group, the expression of PTEN mRNA in left ventricle of captopril group was upregulated, which were similar to that of control group.

CONCLUSIONPTEN maybe plays a negative regulation role in the process of cardiac hypertrophy, and the role of PTEN is closely relative with renin-angiotensin system.

During the process of electroacupuncture (EA) therapy, whether there being a corrosive effect in ac- upuncture needles was observed. Acupuncture needles were inserted into a rabbit's acupoint to perform a 12-hour electrical stimulation with three types of common EA waveform; additionally two needles were put in 0.9% sodium chloride solution with 12-hour direct current. Afterwards, environmental scanning electron microscope was applied to detect the surface physical characteristics of acupuncture needles. As a result, after a 12-hour continued electri- cal stimulation with three types of common EA waveform in the rabbit, there was no corrosive effect in acupunc- ture needles; but the direct current could cause severe corrosion in acupuncture needles. It is believed that there is no corrosion effect on acupuncture needles in current EA treatment, and some accidents reported in literature may be related to quality of EA device or improper manipulation during the treatment.

OBJECTIVETo investigate the effect and mechanism of meloxicam on the inflammatory reaction induced by beta amyloid protein (AB) in Alzheimer's disease (AD) rats.

METHODSThe rat model was established by microinjection of Abeta(1-40) into hippocampus. The expression of NF-kappaB p65 and glial fibrillary acidic protein (GFAP) in hippocampus were detected by immunohistochemistry. The content of GFAP in cortex was tested by Western-blot. The content of TNF-alpha in cortex was tested by ELISA. The expression of IL-1beta mRNA was tested by RT-PCR.

RESULTSThe expression of NF-kappaB p65, GFAP and TNF-alpha as well as IL-1beta mRNA were decreased by meloxicam.

CONCLUSIONMeloxicam can reduce the proliferation of astrocyte by decreasing the expression of GFAP in AD model rat's hippocampus and cortex. And the depression of NF-kappaB p65 may significantly decrease the expression of TNF-alpha1 and IL-1beta to lessen the inflammatory reaction in cerebral tissue.

AIMTo investigate the effect of Naoyikang serum on the damage induced by glutamate in hippocampal neuron.

METHODSMorphological observation, MTT assay and nuclear DNA-associated fluorescence with DAPI dye were applied to evaluate the viability of hippocampal neuron, immunocytochemistry and RT-PCR were used to determine the expression of PTEN.

RESULTSA decreased viability and increased expression of PTEN were shown in hippocampal neuron in response to the treatment with glutamate. It was shown that the percentage of cell death and the expression of PTEN were reduced by the treatment with Naoyikang serum.

CONCLUSIONThese results suggest that Naoyikang may prevent the toxicity of glutamate by suppressing the expression of PTEN.

AIMTo investigate the mechanisms of Naoyikang (Traditional Chinese Medicine) on the Alzheimer's Disease (AD) model mice induced by D-galactose (D-gal) and NaNO2.

METHODSThe mouse model was established by intraperitoneal injection of D-gal and NaNO2. The capacity of learning and memory was tested on mice with electrical maze; the content of nitric oxide (NO) and the activity of monoamine oxidase-B (MAO-B), glutathione peroxidase (GSH-PX), Na(+) -K(+) -ATP enzyme and Ca(2+) -ATP enzyme in cerebral cortex and hippocampus were assayed by biochemical methods; expression of Bax and Bcl-2 mRNA was detested by RT-PCR.

RESULTSNaoyikang could ameliorate the capacity of learning and memory of AD model mice and reduce MAO-B activity in the brain tissue and activate the activity of Na(+) -K(+) -ATP enzyme and Ca(2+) -ATP enzyme in the brain tissue and decrease the expression of Bax mRNA, but increase the expression of Bcl-2 mRNA in the model brain tissue.

CONCLUSIONNaoyikang could protect AD model mice induced by D-gal and NaNO2. It could modify the metabolism of monoamine neurotransmitter in brain through reducing MAO-B activity and protect neurons by activating the activity of Na(+) -K(+) -ATP enzyme and Ca(2+) -ATP enzyme and decrease Bax expression and increase Bcl-2 expression in the model brain tissue.
