AIM To investgate the changes in the expression of CREB and p-CREB in the cortex of ethanol dependent rats. On other hand, the effects of fluoxetine on these changes were also studied. METHODS Ethanol was administered in drinking water at the concentration of 6% V/V, for 28 d. The expression of CREB and p-CREB in the rat cortex were measured by immunohistochemistry methods. RESULTS It was found that chronic ethanol treatment and its withdrawal did not modify the expression of CREB in the rat cortex. However, the levels of p-CREB in the frontal and piriform cortex of rats were significantly decreased during ethanol withdrawal, and respectively decreased 57.28%?55.84% compared to control rats at 24 h after ethanol withdrawal. When fluoxetine (ip, 10 mg?kg -1) were administried concurrently with ethanol, it can significantly dampen alcohol withdrawal symptoms and antagonize the down-regulation of the phosphorylation of CREB in the frontal and piriform cortex of rats at 24 h after ethanol withdrawal, the expression of p-CREB protein respectively increased 292 58%,128 44% compared with rats intaking ethanol. CONCLUSION CREB may be one of the substance of the signal transduction process for ethanol dependence. Fluoxetine can reverse the decreased p-CREB levels in rat cortex induced by ethanol withdrawal, which may be the part reason of fluoxetine dampening alcohol withdrawal symptoms.

To assess the efficiency and reliability safety of ganciclovir to herpes simplex virus keratitis.
●METHODS: All of the randomized controlled trials for the study of ganciclovir versus acyclovir in the treatment of herpes simplex virus keratitis were collected from Cochrane Library, EMbase, PubMed, Chinese Bio -medicine Database, China Journal Full-text Database, VlP Database and WanFang Database. Then the data were extracted and evaluated by two reviewers independently. Risk of bias assessment was evaluated by a tool recommended by Cochrane Library. Revman 5. 0 software was used for statistical analysis.
●RESULTS: Finally, 14 randomized controlled trials were included, 4820 patients totally. Subgroups were used according to the number of patients and diseased eyes as well as the difference of follow-up time. For and relapse rate, ganciclovir group was overmatch acyclovir group. There were statistical differences between the two groups [RR= 1. 22, 95%CI (1. 10-1. 36); OR = 4. 50, 95% CI (2. 02-10. 04); RR = 0. 23, 95% CI (0. 10-0. 52)]. Compared with acyclovir, ganciclovir had less side - effect. There were statistical differences between the two groups [RR = 0. 12, 95%CI (0. 03 - 0. 46)]. All of the side effects of the two groups can be relieved by themselves.
● CONCLUSlON: Current evidence suggests that the ganciclovir is more efficient and safe than acyclovir in the treatment of herpes simplex virus keratitis.

The accommodative function before and after laser in situ keratomileusis (LASIK) was observed, and the effect of LASIk on accommodation was investigated. In a prospective clinical trial, 48 myopic patients (96 eyes) subject to bilateral LASIK in Refractive Surgery Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology (China) from March 2006 to June 2006 were selected and studied. Refractions, accommodative range, amplitude of accommodative response and high frequency component (HFC) of accommodative microfluctuations were measured with NEDIK-730A before and one week and 30 days after operation. Dominant and non-dominant eyes were determined by hole-in-card method. It was found that all of the operative eyes showed an uncorrected visual acuity of 0.8 or better one week postoperatively, and 1.0 or better 30 days postoperatively. Compared with those preoperatively, accommodative range and HFC had no significant difference at first week and 30th day after operation in both dominant eyes and non-dominant eyes (P>0.05), but there was a significant difference in the amplitude of accommodative response/accommodative stimulus ratio (A/S) after operation (P<0.01), and no significant difference was found in accommodation between one week and 30 days postoperation. No ocular dominance's change was noted. There was no significant difference in accommodative function between dominant eyes and non-dominant eyes. It was suggested that LASIK produced no significant effect on accommodation.

ObjectiveTo observe the effect of nursing interventions on improvement of psychological actions and quality of life of patients with Alzheimer disease. Methods50 patients with senile dementia diagnosed in our hospital were chosen.They were divided into the observation group and the control group with 25 patients in each group.All patients were taken with AD routine nursing care after admission.The observation group was taken with rehabilitation nursing interventions based on AD routine nursing care.The mini-mental state examination (MMSE)and the daily life ability scale (ADL)were used to evaluate the quality of life after nursing intervention. ResultsThe patients' MMSE score in the observation group was significantly higher than the control group,the difference was statistically significant.The ADL score of the observation group was significantly lower than the control group,the difference was statistically significant. ConclusionsThe use of integrated care intervention can significantly improve the cognitive function in AD patients,and improve daily living ability and quality of life significantly.

Objective To explore the ultrasonographic, clinical and histopathological characteristics features of primary uterus lymphoma. Methods The clinical, sonographic and histopathological characteristics of nine patients who were pathologically comfirmed as primary uterus lymphoma were analyzed. Results Among the nine cases of primary uterus lymphoma, three lesions were found in the uterine bodys and 6 were found in the cervixes. Two patients with uterine body lymphoma had painless pelvic masses and six patients with cervix lymphoma had contact bleeding, including irregular vaginal bleeding in four patients. In sonograms, six lesions showed remarkable hypoechogenicity with homogeneous internal echogenicity;the margins of most lesions were circumcribed;all lesions had posterior enhancement. In color Doppler lfow imaging, abundant vascularities were detected in eight lesions. In the cases of uterine body lymphoma, all of the uterine bodys showed diffuse symmetrical enlargement without disruption of the endometria, while in ifve cases of cervix lymphoma, the tumors showed the shape of lobule. The pathological examination showed that all tumors were diffuse B-cell type non-Hodgkin lymphoma. Conclusions Primary uterus lymphoma has some clinical and ultrasonic features, including contact bleeding or irrgular vaginal bleeding, diffuse symmetrical enlargement of uterine body, complete endometria, remarkable hypoechogenicity, homogeneous echogenicity and posterior enhancement. Final diagnosis depends on the histopathology.

Objective To observe the stressor characteristic of patients with maintained hemodialy-sis (MHD). Methods The Chinese version of bemodialysis stressor seale(HSS) was adopted among 436 bemodialysis participants and the results underwent analysis. Results Among 436 patients psychological stressors> physiological stressers > social stressors, the most severe stressors included the requirement of long-term dialysis, the rest showed sequence from high to low: medical cost, concerning about the future,changes in family responsibility and decrease in sexuality. The slightest stressors included decreased ability to procreate, being limited in some styles of clothing, arterial and venous stick, reversal in family role with the children and changes in body appearance. Significant differences existed in patients with different age,gender, education background, working status and economic status, it manifested as follows: the more elder-ly, the more severity of stress, male patients had more severe stress than the female, patients with higher e-ducation background showed lower stress level, patients who kept working had lower level of stress, pa-tients who had better economic status showed lower stress level. Conclusions MHD patients often expe-rience high stress levels. Some measures should be taken to help MHD patients to cope better with stress.

Objective To observe the effects of sodium arsenite (NaAsO2) on apoptosis in primary cultured rat cerebellar granule cell and nerve globin mRNA expression.Methods Twenty 7-8 days postnatal Wistar rats were selected and decapitated cerebellar cortex, granular cell suspension was prepared and 4 × 109/m2 cells were seeded in the culture flask.Cells were exposed to different concentrations NaAsO2 [0 (control), 2, 5 and 10 μmol/L] for 24 h and intracellular reactive oxygen species (ROS) content and apoptosis were determined by laser confocal,while real-time quantitative PCR was used to detect mRNA expression in cultured cells after 24 and 48 h cell culture.Results Fluorescence intensity of ROS of 0, 2, 5, 10 μmol/L fluoride groups were 421.32 ± 53.52,1 082.09 ± 321.58, 2 223.02 ± 1 011.37 and 1 366.87 ± 102.14, the difference was statistically significant (F =5.873,P ＜ 0.05);Apoptosis rates were (8.91 ± 5.63)％, (26.46 ± 1.77)％, (43.65 ± 14.45)％ and (56.04 ± 6.95)％, the difference was statistically significant (F =18.369, P ＜ 0.05);24 h nerve globin mRNA expression were 1.00 ± 0.06,0.77 ± 0.22, 0.43 ± 0.18 and 0.42 ± 0.14, the difference was statistically significant (F =18.235, P ＜ 0.05);48 h nerve globin mRNA expression were 1.00 ± 0.01, 0.89 ± 0.09, 0.60 ± 0.16 and 0.08 ± 0.02, the difference was statistically significant (F =80.843, P ＜ 0.05).Conclusion With increased NaAsO2 concentration, ROS and apoptosis levels are increased, while nerve globin mRNA expression is significantly reduced, suggesting that after the body is stimulated, protective proteins might be consumed, further suggesting nerve globin expression might be involved in nerve damage caused by arsenic.
