Objective To analyze the cost-effectiveness of integrated pharmaceutical care (IPC) in community-based patients with chronic obstructive pulmonary disease (COPD).Methods The COPD patients were divided randomly into intervention group (group A,n =79) and control group (group B,n =71).Group A received the IPC intervention measures,including serial lectures of pharmaceutical knowledge,home supervision and web-based communications for while group B group had none.Results As compared with group B,group A obviously improved on the knowledge of pharmaceutical treatment effect and side effect (95.1％,67.4％ vs.63.1％,21.9％,x2 =12.445,P=0.000 vs.x2 =55.557,P=0.000).There were notable differences between two groups [ ( 1.77 ± 1.23 ) vs.( 2.42 ± 1.66 ) s,t =2.583,P=0.011],pulmonary rales [ (0.01 vs.0.01)s,Z =2.370,P=0.018],6-min walk distance (6 MWD) [ (457 ± 67 ) vs.(425 ± 72) m,t =2.760,P =0.007 ],vital capacity ( VC ) [ ( 1.60 ± 0.25 ) vs.( 1.49 ± 0.23 ) L,t =2.718,P =0.007 ) ] andquality-of-life items ( 48 ± 10 vs.52 ± 11,t =2.624,P =0.010) after intervention.Analyze of cost-effectiveness show that groupA was superior to group B [ total effect total cost(TE/TC =764.6/4936,15.49％ )vs.(TE/TC =1509.4/4708),32.06％,x2 =6.183,P ＜ 0.01 ].Conclusion IPC can improve the disease condition and achieve excellent cost-effectiveness for community-based COPD patients.

ObjectiveTo investigate the relationship between platelet-derived growth factor (PDGF)-B and pre-eclampsia or eclampsia by comparing the expression of PDGF-B mRNA and PDGF-BB protein in the placentas from pregnant women with normal pregnancy,pre-eclampsia or eclampsia.Methods The expression of PDGF-B mRNA and PDGF-BB protein were respectively determined with RT-PCR and immunohistochemistry combined with the analysis of computer microphotography in the placentas from 20 mild pre-eclampsia (mild pre-eclampsia group),20 severe pre-eclampsia (severe pre-eclampsia group),3 eclampsia (eclampsia group) and 20 normal pregnancy (control group).ResultsThe expression of PDGF-B mRNA and PDGF-BB protein in the placentas of mild pre-eclampsia group,severe pre-eclampsia group and eclampsia group ( 1.56 ± 0.30 and 1.32 ± 0.34,1.91 ± 0.28 and 2.00 ± 0.41,2.57 ± 0.06 and 2.73 ± 0.15)were higher than those of control group ( 1.38 ± 0.25 and 1.01 ± 0.26) with significant differences (P＜ 0.01 ).The expression of PDGF-B mRNA and PDGF-BB protein in the placentas of severe pre-eclampsia group and eclampsia group were higher than those of mild pre-eclampsia group (P ＜ 0.01 ).The expression of PDGF-B mRNA and PDGF-BB protein were positively correlated with the degree of the disease (r =0.691,0.797,P ＜0.01 ).ConclusionsPregnant women with pre-eclampsia and eclampsia have higher expression of pDGF-B in the placentas.PDGF-B may play an important role in the development and progression of pre-eclampsia and eclampsia by promoting atherogenesis in the placental vessels.

Drug reservation wag investigated in 2077 community residents.We found that most drugs were obtained from the hospitals(83.78%),kept at a relatively lower place(69.23%),packed in box(75.25%),and did not meet the storage requirement(72.60%).Half of the overdue drugs(median time,12 months)were used for internal treatment.This study suggests that there might be unsafe drug storage in communities.

Objective To assess oral health knowledge and behaviors of self-care among HIV infected patients in Yunnan, China. Methods Questionnaire survey was performed to collect the information about behaviors of oral self-care and seeking medical advice and diets of 216 HIV-infected patients who came from the Third Hospital of Kunming. The data were then statistically analyzed. Results Half of the patients were diagnosed over six months. The smoking of the HIV-positive were serious and the gingival bleeding was less, but there was obvious discomfort in oral cavity when eating. In addition,the standard method of cleaning teeth was below 20%, less of 50%patients could clean the oral cavity in time after diet and they didn't replace their toothbrushes timely. Over half of patients asked artificial tooth and exodontias on treatment. Conclusion It is necessary to pay more attention to the oral health knowledge and self-care behaviors of HIV-infected patients so as to improve the quality of life.

ObjectiveTo observe the effect of exercise training on chronic obstructive pulmonary disease (COPD) stable patients in community. MethodsTraditional Chinese exercise prescription was given to 20 COPD patients. They were assessed with 6-minute walk distance (6MWD), the Borg scale and the St. George's Respiratory Questionnaire (SGRQ) before and after the training. ResultsThe Borg scales dropped from (4.45±2.04) to (3.15±2.13) （P＜0.05）. 6MWD increased from (370.32±74.48) m to (403.75±76.15) m （P＜0.05）. SGRQ scores also showed statistical significant difference （P＜0.05）. ConclusionExercise training can improve the tolerance and decrease dyspnea in COPD patients in stable stage. It also can improve the quality of life.

Objective To investigate the effect of diabetes on clinical efficacy of transcatheter arterial chemoembolization (TACE) in the treatment of non-viral hepatitis hepatocellular carcinoma (HCC). Methods Retrospectively analyzed the clinical data of 367 non-hepatitis virus HCC patients treated by TACE, included 153 diabetes mellitus cases (test group) and blood glucose of 214 patients was normal (control group). To assess the treatment effect after 1 month of TACE based on response evaluation criteria in solid tumors, include complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), and calculate the disease control rate. Through 6 to 75 months follow-up to observed long-term efficacy, record the time to progression (TTP) and overall survival (OS) time. Survival rate were analyzed using Kaplan-Meier method and Log-rank analysis by SPSS 16.0. The single-factor analysis was used to analyze variables which variables that differed were analyzed by Cox regression. Results The disease control rate of test group was 69.9%(107/153) and control group was 74.3%(159/214), the difference was no statistically significant (P=0.125). The median time to progression (mTTP) and median overall survival (mOS) of test group were 10.0 and 15.0 months;and the mTTP and mOS of control group were 14.0 and 19.0 months, the difference were statistically significant (P=0.023 and P= 0.026). Tumor diameter ≥4.5 cm, numbers of tumor ≥3, invasion of blood vessels, α-fetoprotein≥200 μg/L, Eastern Cooperative Oncology Group score and diabetes were risk factors for OS of HCC patients. Conclusion Diabetes is unfavorable factors for overall survival of non-hepatitis HCC tread by TACE.

Objective To investigate the clinicopathological features and prognoses of papillary glioneuronal tumor (PGNT), and to improve the understanding of clinical worker on the tumor. Methods Three patients with PGNT got conformation in our center from July 1, 2011 to Apral 20, 2019, were chosen. The clinical features, histopathological characteristics, immunohistochemical findings, and prognoses of these patients were retrospectively analyzed. Results Two patients were female and one was male. Two tumors were located in the lateral ventricle and one in the temporal lobe. All patients presented with headache, and two exhibited dizziness. Imaging showed solid or cystic mass with well-defined boundary. Microscopically, it was characterized by papillary structures covered by single to multiple layers of small cuboidal gliocytes, and neurocyte-like cells scattered between the papilla. Immunohistochemically, the tumor cells covering papilla were positive for glial fibrillary acidic protein and oligodendrocyte transcription factor 2, and neurocyte-like cells were positive for synaptophysin; and the tumor cells were negative for isocitrate dehydrogenase 1 and silk/threonine specific protein kinase gene BRAF V600E. The proliferating cell nuclear antigen Ki-67 labeling index ranged from 1％-2％. Three patients were followed up for 12, 24 and 48 months after tumor resection, respectively, and no recurrence was found. Conclusion PGNT is an uncommon and variant of mixed neuronal-glial neoplasm with low-grade malignancy; the prognosis is good after gross total resection.
