Objective To study the possibility of fetal cardiac rhabdomyoma diagnosed by ultrasonography,and the relationship between the fetal cardiac rhabdomyoma and family tuberous sclerosis. Methods High resolution ultrasonic equipment with fetal cardiac software was used. The main cross section of four chamber view was studied mainly. The location, the number of the tumor and the outflow tract of left and right ventricular cordis were scanned carefully, the maternal abdominal scan was performed as well. Results Five cases of fetal cardiac rhabdomyoma were found by routine prenatal ultrasonography, and were confirmed by autopsy. Among them, one case were associated with maternal tuberous sclerosis. Conclusions Fetal cardiac rhabdomyoma associated with tuberous sclerosis. Fetus with cardiac rhabdomyoma frequently die of cardiac failure; since the prognosis of the tuberous sclerosis with neural sclerosis was very poor, when the fetal cardiac rhabdomyoma was detected prenatally, the possibility of tuberous sclerosis should be considered, also relative examination must be performed to the mother to decrease the perinatal mortality.

Modern management is in essence management of people and the idea and strategy of humanistic management infiltrate into various management activities of a hospital. Our hospital has attempted to enhance the ideological quality and vocational level of the nursing staff by the theory of humanistic management. As a result of such measures as stimulating the nursing staff's thirst for knowledge, enlarging the scope of rewards, increasing the work pressure of young nurses in a proper way, providing room for the free development of head nurses, implementing dynamic management, and adopting democratic management with a high degree of openness, the ideological quality of the nurses has been greatly enhanced. At the same time, measures have been taken to ensure from 3 links that their vocational level keeps improving as well.

Objective To investigate the anticancer effects and molecular mechanism of betulinic acid (BA)on Raji cells in vitro.Methods The effects of BA on the growth of Raji cells were studied by MTT assay.Apoptosis was assessed by Annexin-V/PI double-labeled cytometry.The influence on cell cycle was studied by flow cytometer.The cyclin D3 mRNA expression was checked by Western blotting and RT-PCR techniques.Results BA showed obvious inhibition on proliferation,as well as induction potency of apoptosis on Raji cells in vitro in a time-and dose-dependent manner by Annexin-V/PI double-labeled method.With the IC_(50)value for 24 h being(39.44?0.65)?g/mL,Raji cells treated with BA showed ac- cumulation in G_0/G_1 phase and reduction in the percentage of cells in S phase.The cyclin D3 mRNA ex- pression and protein were sharply decreased in Raji cells treated with BA.Conclusion BA could inhibit the proliferation of Raji cells by regulating the cell cycle that arrests cells at G_0/G_1 phase and induces apop- tosis of Raji cells.The antitumor effects of BA may be related to down-regulation of the expression of cy- clin D3.

ObjectiveTo study the prevalence rate of post-stroke depression (PSD) of the elderly in the community and analyze risk factors of them. MethodsThe elders of the age of 60 or over were sampled as subjects from a community. Zung (SDS) was used as screening instruments and Hamilton rating scale for depression (HRSD-24) as evaluating scales. The prevalence rate of PSD was surveyed. A structured questionnaire was used and physical examination was carried out. Risk factors measured included baseline information, daily habits, and history of main diseases (hypertension, coronary heart disease, diabetes mellitus, myocardial infarction, and so on). The relationship between risk factors and PSD was analyzed.ResultsThe prevalence of PSD was 9.5%. The risk factors for PSD were life quality and age. ConclusionPost-stroke depression disturbs elder's health and rehabilitation. The prevalence rate and harm of PSD are higher than depression without stroke.

OBJECTIVE: To explore the expression levels of three T-type calcium channel receptors (α1G; α1H; α1I) in the cochlea and spiral ganglion neurons of C57BL/6J mice with different ages. METHOD: Thirty cases of C57BL/6J mice were divided into three groups (6-8 W, 24-26 W, 42-44 W) according to the age. The expressions of three T-type calcium channel receptors were quantified by RT-PCR after hearing thresholds measured by ABR. RESULT: Three receptors were detected in the cochlea and spiral ganglion neurons of 6-8 W C57BL/6J mice. The quantitative results showed that the expression levels of α1H and α1I were highest among three receptors in spiral ganglion neurons and in the cochlea respectively. The expression levels of three receptors significantly decreased with age,especially at the age of 4244 W. CONCLUSION The expression of T-type calcium channel receptors reduced with age in the inner ear of C57BL/6J mice.

Objective To evaluate the performance of an improved skin prick test in the screening for allergens.Methods A total of 475 patients with chronic urticaria who aged from 3 to 81 years were enrolled in this study,and classified into the control group (n =235) and research group (n =240).Traditional and improved skin prick test were conducted in the control and research group respectively.The allergen detection rate was compared between the two test methods.Results The allergen detection rate was 65.4％ and 67.2％ respectively for the improved and traditional skin prick test,respectively (P ＞ 0.05).House dust mites were the most common sensitizing agent.Conclusion The improved skin prick test can offer reliable evidence for chnical diagnosis with a relatively convenient and safe procedure.

Objective To study the effect of whole-process nursing intervention on comfort of patients undergoing radial artery puncture. Methods 100 patients with radial artery puncture from July, 2007 to June, 2008 were divided into the control group and the experimental group with 50 cases in each group accord-ing to time sequence. Routine whole nursing mode was used in the control group, the whole-process nursing intervention mode based upon routine nursing mode under the instruction of evidence-based method was used in the experimental group. Pain, psychological tensity, body numbness, success rate of radial artery puncture, patients' satisfaction degree were compared between the two groups. Results Every indexes of the experi-mental group were better than those of the control group. Conclusions The whole-process nursing interven-tion mode can promote the comfort degree of patients undergoing radial artery puncture.

Objective To evaluate the diagnostic value of deep venous thrombosis(DVT)on lowerlimb venous ultrasonography combined with right ventricular dysfunction (RVD) on transthoracic echocardiography(TTE) in patients with acute pulmonary thrombo embolism(PTE). Methods This prospective multicenter control trial included 520 patients with confirmed acute PTE from 41 hospitals between June 2002 and February 2005.Results The incidence of RVD and DVT was associated with the severity of PTE.There were 57.0%(207/363)patients with RVD,49.6%(1 80/363)patients with DVT,265(73.0%)patients with RVD and/or DVT,and 121(33.3%)patients with combined sign of DVT plus RVD in the whole population.As to major PTE population,206(99.5%)patients had RVD and 121 (58.5%)patients had DVT.In addition,the rate of RVD was much greater in proximal PTE than in lobar PTE and segmental PTE(78.7%,51.4%and 21.7%,respectively,P＜0.001).DVT occurred more frequently in proximal PTE than in lobar PTE and segmental PTE(61.7%,46.8%and 37.0%,respectively,P＜O.001).The incidence of the combined sign was 51.1%,24.3%and 8.7%,respenctively (P＜0.001).Conclusions The incidence of the combined sign of RVD plus DVT was associated with the severity of PTE and the localization of emboli.The combined sign of RVD plus DVT help diagnose major PTE especially in emergency department.
