Objective To carry on the training of empathy ability among nursing undergraduates and understand its influence on that empathy and professional commitment. Methods Nursing undergraduates of two classes in the Chengdu University of TCM were selected as the objects in this study, who had accepted Nursing Psychology. The students in one class (52 cases) as the intervention group, while the students in the other class (61 cases )as the control group. Routine education was used in the control group, the empathy education was used in the intervention group in addition. On the basis of the Jefferson Scale of Empathy (JSE) and Nursing professional commitment Scale a survey on empathy ability among nursing undergraduates and professional commitment had done for the investigation of its influence on those two sides. Results After the training, the general professional commitment scores in the intervention group was 85.89 ± 11.86, which was significant higher than 77.53 ± 11.93 in the control group (t=3.822,P < 0.01). The final scores of commitment and empathy had significant relation with their respective latitudes (P < 0.05 or <0.01). Conclusions The training of empathy ability among nursing undergraduates affects their empathy ability and professional commitment. And students’professional commitment can be improved through some targeted trainings.

Objective:This study aims to explore the relationship between serum response factor (SRF) expression level and gas-tric cancer progression by detecting SRF expression level in cancer cells. Methods:The SRF gene in SGC-7901 cells was silenced by RNA interference. Transfection efficiency was detected by fluorescence microscopy, cell proliferation by CCK 8 method, SRF gene and protein expression level by real-time polymerase chain reaction and Western blot, and cell cycle by flow cytometry. Results:Cell treat-ment with siRNA-SRF induced significant reduction in SRF mRNA levels. Western blot analysis showed that SRF protein decreased by 40.1%in the siRNA group compared with that in the control group (P<0.05). Compared with the blank, negative, and mock transfection control groups, cell proliferation of the siRNA-SRF group decreased. The inhibition ratio reached 64.24%, as measured by the CCK-8 assay (P<0.05). Treatment with siRNA could block SGC-7901 cell cycle at G0/G1 phase (P<0.05). Conclusion:SRF expression is close-ly associated with gastric carcinoma cell proliferation. SRF protein level detection can provide a certain reference value in evaluating malignant gastric carcinoma progression. SRF is possibly an important target for the prevention and control of gastric cancers.

Objective To explore the biological characteristics of mucinous adenocarcinoma deriving from chronic anal fistula and its diagnosis and treatment. Method A retrospective study was made to analyze clinical and pathological features of 4 cases of chronic anal fistula from which mucinous adenocarcinoma developed in our hospital from 1986 to 1997. Results There were three males and one female averaging 50 years old. All patients had chronic history of perianus abscess or anal fistula. This rare mucinous adenocarcinoma originated from the anal fistula and the associated anal glands. The canceration of anal fistula was due to chronic inflammation and scarring. The definitive diagnosis of the carcinoma depends on biopsy of the fistula and the related tumor. Metastasis to groin lymph nodes was found in two patients. Three cases underwent Miles operation with chemotherapy; two of the three patients also had resection of groin lymph nodes. Three patients survived more than five years. One patient treated only with chemotherapy died three months later. [WT5”HZ] Conclusion [WT5”BZ] Mucinous adenocarcinoma following chronic anal fistula is less malignant and has better prognosis compared to primary rectal and anal mucinous adenocarcinoma.

BACKGROUND:Long-term use of corticosteroids (hereinafter referred to as hormone) after renal transplantation could obviously lead to adverse reactions. Immunosuppressive regimen with less and no hormone has been a hot focus in the study of renal transplantation al over the world. However, reduction or withdrawal of hormones has a certain risk. At present, there is no unified scheme. Because urine protein can be immediately detected after tubular injury, to monitor urine protein can find the renal dysfunction after transplantation in recipients undergoing renal transplantation, which can gain time for clinical therapy. OBJECTIVE:To discuss the influence of hormone (prednisone) removal on the occurrence of urine protein in recipients undergoing renal transplantation. METHODS:A total of 35 recipients undergoing renal transplantation after removal of prednisone received immunosuppressive regimen of cyclosporine A or tacrolimus+mycophenolate mofetil bivalent. Initial dose of prednisone was 30 mg/d, and then gradual y reduced by 5 mg per week, and withdrawn at 1 month after renal transplantation. There were 16 cases in cyclosporine A group and 19 cases in tacrolimus group. Urine protein was measured and quantified at 3, 6, 12 and 24 months after renal transplantation and 3, 6 and 12 months after addition of prednisone in both groups. Simultaneously, serum creatinine, fasting glucose, body mass increases, the rate of acute rejection, infection, patient/graft survival at 2 years after renal transplantation and urine protein at 24 hours before and after adding hormone were recorded. RESULTS AND CONCLUSION:For the two groups, urineα1-microglobulin started to rise after 6 months of removal of prednisone. Urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin ascended obviously at 12 months. Urinary protein was positive in five cases of cyclosporine A group and in three cases of tacrolimus group. At 24 months, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously. Urinary protein was positive in cyclosporine A group with 11 cases and in tacrolimus group with 10 cases. 24-hour urinary protein quantity was more than 1 g in every case. On this base, we made the patients to take more prednisone for 6 months, so urineα1-microglobulin and urinary microalbumin began to descend. Each group had one case of positive urinary protein turning to negative. Twelve months after the adjustment of the prednisone, urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin descended respectively. Positive urinary protein turned into negative:in cyclosporine A group with two cases and in tacrolimus group with three cases. 24-hour urinary protein quantity was around 0.7 g. Two years after renal transplantation, serum creatinine and acute rejection rates were higher in the cyclosporine A group than in the tacrolimus group (P<0.05). No significant difference in fasting glucose, body mass increase, infections, and patient/graft survival was detectable between both groups. Results suggested that removal of prednisone greatly affected urine protein in recipients undergoing renal transplantation. In particular, at 2 years after renal transplantation, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously, and the security needs further research.

To evaluate the efficacy and safety of compound Decumbent Corydalis Rhizome (DCR) in treating patients with knee osteoarthritis (OA). Totally 79 patients with knee osteoarthritis were selected from out-patient and inpatient departments of West China Hospital and randomly divided into the test group and the control group. The test group (n = 41) was given Compound DCR with the dosage of 1.8 g · d(-1), while the control group (n = 38) was administered with diclofenac sodium with the dosage of 75 mg · d(-1). After 12 weeks of treatment, the total efficacy rates based on patients/physicians evaluation for experimental and control groups were 68.29%, 63.41% and 71.05%, 63.16%, respectively, without significant difference between the two groups. Both of the two groups showed significant improvements in the main efficacy indexes (pain on walking 20 m) and minor indexes (tenderness on palpation, Western Ontario and McMaster Universities OA index (WOMAC) and Short-Form Health Survey (SF-36 ), but without significant difference in efficacy between them. The incidence of related adverse events was 24.39% in the test group and 47.37% in the control group, respectively, with significant differences between the two groups (P < 0.05). In the controlled study, compound DCR is as efficient as diclofenac sodium but more tolerable, with a good clinical application prospect.
