Objective To observe the level of supportive care need and quality of life in patients postoperation for breast cancer and ac-cepting chemotherapy, and the relationship between them. Methods From September, 2015 to June, 2016, 235 patients with breast cancer af-ter surgery were conveniently sampled, and investigated with the general situation questionnaire, Supportive Care Need Survey Short-form (SCNS-SF34) and Functional Assessment of Cancer Therapy-Breast (FACT-B). Results A total of 230 patients were analyzed. Patients self-reported to need supportive care in all dimensions of SCNS-SF34, and the most frequency was in the health information (31.30％). The score of FACT-B was (93.25±23.53), that needed further improvement. The needs of supportive care in each dimension negatively correlat-ed with the scores of FACT-B in the dimensions (|r|>0.168, P<0.05) except society/family and function. Conclusion The patients with breast cancer need variety of supportive care, which may impact their quality of life.

Objective To establish a mouse model of acute liver failure induced by lipopolysaccharide /D-galac-tosamine ( LPS/D-GalN) .Methods The optimum dose of LPS/D-GalN was determined by i .p.injection of eight differ-ent doses of LPS and D-GalN into 40 female C57BL/6 mice and observation of their survival time .Then, 32 female C57BL/6 mice were i.p.injected with the optimal dose of LPS/D-GalN and sacrificed at 0, 1, 4, 8 hours after the injec-tion, 8 mice in each group.The control mice received saline injection .Hepatic changes were observed by pathology and se-rum ALT, IL-6, MCP-1 and TNF-αwere measured by biochemistry or flow cytometry .Results LPS (2.5 mg/kg) and D-GalN (0.3 g/kg) were determined as the optimal dose for the establishment of mouse model of acute liver injury .Com-pared with the control group , the hepatocellular damages were progressing in a positive correlation with the time course after LPS/D-GalN administration .The level of serum ALT was significantly increased after LPS/D-GalN administration ( P <0.001).The levels of inflammatory cytokines IL-6, MCP-1 and TNF-αwere increased and reached a peak at one hour after LPS/D-GalN administration and then decreased almost to that of the control group 8 hours later(P<0.001).Conclusions The mouse model of acute liver injury is successfully established by LPS /D-GalN administration , and provide an effective animal model for the study of pathogenic mechanisms of acute liver failure and evaluation of therapeutic drugs .

BACKGROUNDBone metastasis is very common in lung cancer patients. Metastasis to spine can lead to paralysis and fracture, deteriorate the quality of patient's life. The objective of this study is to investigate the diagnostic values of bone scanning (NBS), MRI, CT and X-ray examination to discover bone meastasis of lung cancer, and the therapy of bone metastasis and the prognostic factors.

METHODSAbout 561 consecutive NSCLC cases were analyzed with NBS and compared with other radiological examinations (MRI, CT and X-ray).

RESULTSOut of the 455 positive patients by NBS, 300 cases were confirmed to be with bone metastases by dynamic follow-up, MRI, CT and X-ray, and 5 cases were false negative.The sensitivity and specificity of NBS was 98.36% and 39.45% respectively. The accuracy of NBS was 71.48%. Among the 305 patients with bone metastases, 23 patients had no records, 138 patients had bone pain, the incidence of asymptomatic bone metastasis was 47.21%. Multivariables analysis showed that asymptomatic bone metastasis, flat bone metastases, therapy with disodium pamidronate were significantly good prognostic factors, respectively (P < 0.05).

CONCLUSIONSA whole body NBS examination is preferred for the staging of NSCLC. NBS is necessary for patients with NSCLC. In order to exclude the possible false positive or false negative diagnosis by NBS, CT or MRI could be selected according to the sites of lesions.

OBJECTIVEThis study aims to observe the expression of Sclerostin during movement of orthodontic teeth and determine the effect of this protein on remodeling of periodontal tissues.

METHODSTwenty-four Wistar rats were chosen. Orthodontic forces were applied between the bilateral incisor and first molar to achieve mesial movement. Rats in each group were executed at different time points (0, 1, 3, 5, 7, 14 d). Morphology of periodontal tissue was observed by hematoxylin-eosin (HE) staining. The number of osteoclasts were observed by tartrate-resistant acid phosphatase (TRAP) staining. Sclerostin expression were observed by immunohistochemical staining.

RESULTSHE staining revealed that the resorption of alveolar bone intensified with prolonged movement. Results of immunohistochemical and TRAP staining revealed that Sclerostin expression and number of osteoclasts were related to duration of movement of orthodontic tooth. After staining for 5 days, the number of osteoclasts and Sclerostin expression reached their peak and then began to decline. The numbers of osteoclasts and the expression level of Sclerostin were higher at the compressive side than those at the tensive side.

CONCLUSIONSclerostin affected orthodontic tooth movement by inhibiting the Wnt signaling pathway and by indirectly or directly controlling bone morphogenetic protein.

ObjectiveTo investigate the value of blood lipid indices and albumin-bilirubin index (ALBI) in evaluating the progression of chronic hepatitis B virus (HBV) infection. MethodsA total of 184 patients with chronic HBV infection who visited The Second Affiliated Hospital of Anhui Medical University from June 2016 to June 2017 were enrolled, and according to the stage of the disease, they were divided into ASC group (74 HBV carriers), CHB group (70 patients with chronic hepatitis B), and LC group (40 patients with compensated cirrhosis). A total of 50 healthy individuals were enrolled as health control (HC) group. Blood lipid indices and liver function parameters were measured, and the changes in blood lipid indices and ALBI during the progression of chronic HBV infection were analyzed. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett method was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups; Pearson correlation analysis was used to investigate correlation. Results There were significant differences between the ASC, CHB, LC, and HC groups in blood lipid indices of cholesterol (CHO), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (APOA), and apolipoprotein B (F=12.075, 19.559, 6.554, 9.392, and 5.458, all P＜0.001), and the LC group had significantly greater reductions in the above indices compared with the other three groups (all P＜0.05). There was a significant difference in ALBI between the four groups (F=49.225, P＜0.001); the LC group had a significantly higher ALBI than the other three groups (all P＜005), and the ASC and CHB groups had a significantly higher ALBI than the HC group (both P＜0.05). CHO, HDL-C, LDL-C, and APOA were negatively correlated with ALBI (all P＜0.05), among which CHO and HDL-C had the strongest correlation with ALBI (r=-0.310 and -0.266, both P＜0.001). ConclusionIn patients with chronic HBV infection, blood lipid indices and ALBI can reflect the degree of liver function damage, especially in patients with liver cirrhosis.

Objective To analyze and compare the pathological changes of lung tissue in mice infected with the novel H7N9 influenza virus and 2009 pandemic H1N1 influenza virus, respectively, and to preliminarily study the mecha-nisms of acute lung injury induced by those virus infection .Methods SPF 6-week old BALB/c mice ( body weight 18-20 g, male∶female=1∶1) (n=3 in each subgroup) were intranasally infected with H7N9 virus and H1N1 virus, respec-tively.The behavior and survival time of mice after virus infection were observed and the survival rates were analyzed .The heart, liver, spleen, lung, kidney, intestines, and brain were collected at indicated time points for histopathological exami-nation using H&E staining .The distribution of virus antigen was detected by immunohistochemistry .The neutrophil infiltra-tion was also observed .The correlation of lung injury with virus replication and host immune responses was analyzed .Re-sults The lung and spleen injury of mice infected with H 7N9 virus was slighter and their survival rate (100%) was high-er than those of mice infected with H1N1 virus.The damages of the lung and spleen in H1N1virus-infected mice were more severe than that in H7N9 virus-infected mice, and all the 10 mice in this group died within 9 days after virus inoculation . The distributions of both the virus antigens were mainly in the bronchial epithelial cells , a few stromal cells and alveolar ep-ithelial cells .The levels of virus replication in the two groups were not significantly different .There were more intense neu-trophil infiltration in the lung and inflammatory response in the H 1N1 virus-infected mice than those in the H7N9 virus-in-fected mice .Conclusions There are some differences of the pathological characteristics and extent of lung injury in the mice infected with H7N9 virus and H1N1 virus, respectively.The virus replication is a precipitating factor but not the deci-sive factor of the lung injury , and there is a close relationship between the host immune responses and acute lung injury .

Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancer, with a 5-year survival rate of less than 15%-19%, and more than 80% of the patients with lung cancer have progressed to advanced stage (Stage IIIb-IV) when they are clearly diagnosed. The comprehensive treatment mainly based on chemotherapy as the primary form is now considered as the major therapy method for advanced NSCLC without actionable driver gene mutations. Pemetrexed plus platinum doublet as well as single-agent pemetrexed are respectively the first-line major regimens recommended by guidelines and the second-line optional regimens. Yet the third-line treatment or beyond in advanced NSCLC is not evidence-based but conducted based on patients' previous medications, which is one of the most commonly used clinical methods. As pemetrexed is a multi-target chemotherapy drug with high efficiency but low toxicity, pemetrexed re-challenge strategy in advanced NSCLC is also a reasonable choice. We report one effective individual case that adopted pemetrexed re-challenge strategy in advanced NSCLC for three times, and at the same time conduct the relevant literature review.

Objective To investigate the association of copy number variations (CNVs) in the FCGR3A and FCGR3B genes with different outcomes and disease progression after hepatitis B virus (HBV) infection. Methods Peripheral blood samples were collected from 841 patients with chronic HBV infection and 296 patients with self-limited HBV infection, an according to the degree of disease progression, the patients with chronic HBV infection were further divided into chronic hepatitis B (CHB) group, liver cirrhosis (LC) group, and hepatocellular carcinoma (HCC) group. The AccuCopy technique was used for the quantitative analysis of CNVs in the FCGR3A and FCGR3B genes in peripheral blood. The independent samples t -test was used for comparison of continuous data between two groups, and a one-way analysis of variance and the Kruskal-Wallis H test were used for comparison between multiple groups; the chi-square test was used for comparison of categorical data between groups. The chi-square test was also used to investigate the difference in the distribution of CNVs in the FCGR3 gene between different groups. The age-and sex-adjusted logistic regression model was used to investigate the influence of CNVs on the chronicity of HBV infection. Results There was a significant difference in the frequency distribution of CNVs in the FCGR3A and FCGR3B genes between the chronic HBV infection group and the self-limited HBV infection group ( χ 2 =11.406 and 19.143, both P < 0.05). As for disease progression after chronic HBV infection, there were no significant differences in CNVs of the FCGR3A and FCGR3B genes between the CHB group, the LC group, and the HCC group (FCGR3A: χ 2 =3.125, P =0.537; FCGR3B: χ 2 =5.274, P =0.260). There were also no significant differences in CNVs of the FCGR3A and FCGR3B genes between the HBeAg-positive group and the HBeAg-negative group (FCGR3A: χ 2 =1.025, P =0.599; FCGR3B: χ 2 =0.712, P =0.701). Reduction or deletion of the copy number of the FCGR3A and FCGR3B genes was a risk factor for the chronicity of HBV infection (FCGR3A: odds ratio [ OR ]=0.621, 95% confidence interval [ CI ]: 0.513-0.752; FCGR3B: OR =0.594, 95% CI : 0.491-0.719). Conclusion Reduction or deletion of the copy number of the FCGR3A and FCGR3B genes may be a genetic susceptibility factor for the chronicity of HBV infection, but it is not associated with disease progression.
