Objective To observe the effect of herbal medicines with the function of replenish qi and essence for the immune func- tion of patients after mammary cancer operation.Methods The 115 patients of mammary cancer after modified radical operation were randomized into treatment group and control group.The treatment group began to take the decoction of herbal medicines from 7 days before and from the 3rd day after operation.The control group had the same treatment but without taking herbal medicines.The im- mune indices of both groups were tested on the day 7 days before,one day and 14 days after operation respectively.Results In the treatment group,IgA,IgG,IgM were remarkably increased in comparison with the control group 14 days after operation;with the herbal treatment for 2 weeks,CD_4,CD_4/CD_8,IL-2 rised remarkably(P

Objective To clear the clinical efficacy of using early rehabilitation nursing model in the course of clinical nursing in patients with cerebral infarction.Methods Divided 60 patients with cerebral infarction into the observation group (30 cases) and the control group (30 cases) randomly,traditional nursing measures were used in the control group,the early rehabilitation nursing model was used in the observation group in addition.Compared the clinical efficacy,ADL scores,NIHSS scores and the satisfaction between the two groups.Results In the observation group,the satisfaction was 93.33％ (28/30),the efficiency was 90.00％(27/30),which were significantly higher than those in the control group [76.67％(23/30),[66.67％(20/30)].The ADL and NIHSS scores in the observation group was (91.25±11.38) and (8.01±1.05) respectively,which were significantly different with those of in the control group,the ADL and NIHSS scores was (79.37±10.27) and (10.22±1.27) respectively in the control group.Conclusions Early rehabilitation nursing model can effectively improve the never function of patients with cerebral infarction,and then improve their quality of life.

[Abstract ]Objective:To estimate dental maturation norms of permanent dentition in a group of Nanjing children using Nolla's tech-nique.Methods:549 cases of panoramic radiographs (279 males and 270 females)of Nanjing children at the age range of 3 to 16 years were collected for the study.All permanent mandibular teeth on the left side (except for the third molars)were scored according to Nolla's method,and data were presented in tables and used to plot dental maturation curves for the Nanjing boys and girls.Results:Females were found to be more advanced in the degrees of dental development.Dental maturation is significantly associated with chron-ological age (for males and females:r =0.959,P <0.001 and r =0.953,P <0.001,respectively).The mathematical model of them was established,and then the fitting equation was obtained.Conclusion:The dental maturation curve and chronology of permanent dentition can provide the growth norms of permanent teeth for Nanjing children and facilitate the way for dentists to assess the growing children during diagnosis and treatment planning.

Objective:To observe the clinical effect and adverse reaction of capecitabine as first-line monotherapy in elderly patients with stage Ⅱa breast cancer.Methods:From June 2002 to June 2005,71 elderly patients with stage Ⅱa breast cancer received chemotherapy(different scheme:capecitabine group and CEF group) after operation.The efficacies and adverse reactions were evaluated and compared between the two groups.Results:The 3-year and 5-year survival rates of patients in capecitabine group were 97.06% and 94.12%,respectively; the relapse rate was 5.88%; all were comparable to those of CEF group. One of the advantages of capecitabine was its oral administration. The adverse effect of capecitabine was mainly hand-foot syndrome,with an incidence of 82.35%,but was tolerable. The gastrointestinal reaction and bone marrow repression in capecitabine group were significantly lower than those in the CEF group(P

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.
