Objective To investigate the clinical values and influencing factors of1H magnetic resonance spectroscopy(1H-MRS) in breast tumors.Methods Thirty-eight patients with breast tumors confirmed pathologically,including 20 cases of breast cancers and 18 cases of benign tumors examined by dynamic contrast-enhanced MRI and1H-MRS were studied retrospectively in comparison with pathology.The value of1H-MRS in detecting breast cancers was evaluated.Results On1H-MRS,11 breast cancers had increased choline peaks and 3 benign tumors presented increased choline peaks.The sensitivity,specificity and accuracy were 55.0%,83.3%and 68.4% respectively by using choline peak to detect breast cancers.Conclusion 1H-MRS has high diagnostic specificity for breast cancer.The low sensitivity of Choline to be detected rate in breast cancer is mainly dues to the lesions and technique factors.

Objective Review the epidemiology, injuries and assessments for body impairment on the injured children and teenagers in road traffic accidents (RTAs). Methods The data of 256 cases of assessment for body impairment of the injured children and teenagers in RATs was studied retro spectively. Results Boys were injured more than girls, mainly 6-18 years of age. RATs occurred mostly in 10-12a.m and 4-6p.m. The types of vehicles were mostly car and wagon. The commonest accidents were injury of pedestrians. The sites of injures were mainly head and extremities, the commonest injures were fracture, contusion and wound, the degree of internal organ injuries was relatively slight, the fracture of lower extremities was far more often than the upper extremities. Most of the injuries were assessed to be of medial injury. In most of the cases the rate of disability was evaluated to be lighe (33.2%), in which Ⅸ , Ⅹ grade were the commonest. Conclusion The criterion of assessment for body impairment of the injured in RTAs should be broadened properly, some special items for children and teenagers should be added.

Objective To investigate the effect of comprehensive nursing intervention and evaluate its role in the entire clinical course of in the treatment of children with severe burns. Methods A total of 60 children with 1-5 years old with clinical diagnosis of severe burns were randomly divided into experimental group and control group by random digits table method, 30 cases in each group. The control group received routine burn care. The experimental group received comprehensive nursing interventions on the basis of routine burn care and the intervention time covered the entire course of treatment. During hospitalization, the recovery and family social system were evaluated by anxiety scales and social support scales combined with the cure rate and hospitalization of children. Results Before intervention, the score of Anxiety Rating Scale was high in both groups of families, while Social Support Scale was lower, the difference was not statistically significant between the two groups (P>0.05). After intervention, the score of Anxiety Rating Scale and was Social Support Scale were (52.31±7.81), (31.52± 5.48)points in the experimental group, and (62.51 ± 6.52), (23.62 ± 5.62) points in the control group, and there were significant differences (t=5.491 3, 5.512 5, P<0.01). The length of stay was (18.34±3.58) d in the experimental group, and (21.82 ± 4.23) d in the control group, and there was significant difference(t=3.439 6, P<0.05). The cure rate was 93.33%(28/30) in the experimental group, and 56.67%(17/30) in the control group, and there was significant difference(χ2=10.755 6, P<0.05). Conclusions The comprehensive nursing intervention can provide comprehensive refinement of the overall care in children and their families, promote physical and psychological rehabilitation of children with severe burns, and repair their family and social support systems. The comprehensive nursing intervention has far-reaching implications for the rehabilitation of children with severe burns.

OBJECTIVE: To evaluate the anxiety and depression status of patients with nasal septum deviation before and after surgery, and explore the relationship between anxiety and depression and nasal symptoms. METHOD: By means of visual analogue scale (VAS) as the evaluation index of quality of life, self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to analyze statuses before and after surgery. The 98 patients with nasal septum deviation were collected. RESULT: The preoperative SAS/SDS scores of the nasal septum deviation patients were higher than those of the national standards. The level of anxiety and depression were lower than the national norm after treatment. The patients of the normal and moderate SAS/SDS scores felt better after surgery. The patients of the severe SAS/SDS scores felt the symptoms improve poor. CONCLUSION Doctors should pay attention to the application of the SAS/SDS in patients of nasal septum deviation. Surgeon should actively communicate with severe patients in psychological problems, and strictly control the surgical indication of such patients.

Background and purpose: Hepatocellular carcinoma (HCC) is a hypervascular tumor associated with a poor prognosis and lack of effective treatments. Consequently, identifying novel therapeutic strategies are urgently needed. We have previously shown that the kringle 1 domain of human hepatocyte growth factor (HGFK1) is a more effective anti-angiogenesis molecule than angiostatin. In this study, we observed the effects and mechanisms of HGFK1 gene on the HCC. Methods: A recombinant adeno-associated vires carrying the HGFK1 gene (rAAV-HGFK1) was constructed.HCC of rat was induced by McA-RH7777. rAAV-HGFK1 was used to treat the rat, median survival time and metastasis rate were observed. Results: Ten days after tumor cell inoculation, surgery were performed to confirm the tumor formation, PBS, rAAV-EGFP or rAAV-HGFK1 was injected directly into the tumor nodule followed by portal vein injection. Results from our study demonstrated that rAAV-HGFK1 treatment significantly prolonged the median survival time of the HCC bearing rats from 30 days (PBS and rAAV-EGFP groups) to 49 days (rAAV-HGFK1 group). More importantly rAAV-HGFK1 inhibited tumor growth and completely prevented liver, lung and peritoneal metastasis. In the controlled PBS and AAV-EGFP group, liver and peritoneal metastasis rate were both 100%, and lung metastasis rate was 100% and 83%, respectively. While there was no metastasis found in treatment group, with only 33% of ascites happened. This was most possibly due to the primary tumor in liver but not due to the metastasis. Moreover, at a higher magnification (1000×), it was clear that the HGFK1 protein was expressed mainly in the cytoplasma of liver cells. In parallel, IHC staining of CD31 also demonstrated a significantly lower level of microvessel density (MVD) (6.21±1.6) in the liver tumor of the AAV-HGFK1 treatment group, as compared to the two control PBS and AAV-EGFP groups (25.1±2.1 and 26.8±2.5, respectively, P<0.01). HE staining showed that AAV-HGFK1 treatment induced large areas of necrosis in the tumor tissues, while minimal areas of necrosis were observed in the tumor tissue in the control groups. In addition, no toxicity appeared when high dosage (4.8× 1012 vg/rat) of rAAV-HGFK1 was administered in rats. Conclusion: Results from this study demonstrated that HGFK1 inhibited the growth and metastasis of HCC and prolonged the survival time of animals with HCC through anti-angiogenesis effects. No obvious toxicity was observed. It might be the novel promising treatment for HCC and other cancers.
