In appropriate prescribing is a global problem. It is especially salient in China, where drug sales constitute a major portion of health care providers' incomes, price distortions are rampant, and oversight is lax. However, few data exist on the prevalence of inappropriate prescribing in China. This study, the first of its kind in China, examined 230,800 prescriptions written between 2007 and 2009 by 784 community health institutions in 28 cities across China. The data show substantial overprescribing, including twice as many prescriptions for antibiotics as recommended by the World Health Organization and rates of injection that are three times higher than in similar countries. These findings point to the need to integrate rational prescribing into China's ongoing health care reform. M arket-oriented reforms in the past three decades have brought unprecedented economic prosperity to China. At the same time, they dismantled the structure of China's equitable, albeit rudimentary, health care system. Today, with the Chinese Ministry of Health setting very low prices for physician consultation, hospitalization, and services, drug "markups" have become the major source of revenue for health care providers.Unlike the United States and many other countries, China does not have a widespread retail pharmacy system. Patients typically fill their prescriptions at the same hospital or clinic that they visit for care. These health care providers don't receive a dispensing fee but rather earn the difference between wholesale and retail price. Because these drug-related revenues are a major source of financial support for health care providers, one of the detrimental consequences is inappropriate or irrational prescribing. 1The irrational prescribing is further exacerbated by runaway manufacturer prices and lax oversight. This environment poses a serious risk for patients' health and sources of health care. 2Recognizing the ever-worsening problems in basic health care coverage, disease-induced poverty, disparities, and the resulting social instability, the Chinese government has launched a multitude of reforms. Central to the reforms has been the reconstruction of affordable and convenient community health service networks that provide basic disease prevention, medical treatment, rehabilitation, health education, and family planning services within designated urban communities. These networks are composed of health centers, each providing about 50 beds and serving 30,000 to 50,000 residents, and satellite health stations, each serving about 3,000 residents. 4 Most of these institutions are owned or subsidized by municipal governments; the rest are owned by private practitioners, trade organizations, and other nonprofit entities.5 By the end of 2008, 98 percent of the cities in all of China's thirty-one provinces had developed community health service networks. 6 In 2010 China's minister of health, Zhu Chen, Reform In China

Alzheimer's disease (AD) is a frequently observed, irreversible brain function disorder among elderly individuals. Resting-state functional magnetic resonance imaging (rs-fMRI) has been introduced as an alternative approach to assessing brain functional abnormalities in AD patients. However, alterations in the brain rs-fMRI signal complexities in mild cognitive impairment (MCI) and AD patients remain unclear. Here, we described the novel application of permutation entropy (PE) to investigate the abnormal complexity of rs-fMRI signals in MCI and AD patients. The rs-fMRI signals of 30 normal controls (NCs), 33 early MCI (EMCI), 32 late MCI (LMCI), and 29 AD patients were obtained from the Alzheimer's disease Neuroimaging Initiative (ADNI) database. After preprocessing, whole-brain entropy maps of the four groups were extracted and subjected to Gaussian smoothing. We performed a one-way analysis of variance (ANOVA) on the brain entropy maps of the four groups. The results after adjusting for age and sex differences together revealed that the patients with AD exhibited lower complexity than did the MCI and NC controls. We found five clusters that exhibited significant differences and were distributed primarily in the occipital, frontal, and temporal lobes. The average PE of the five clusters exhibited a decreasing trend from MCI to AD. The AD group exhibited the least complexity. Additionally, the average PE of the five clusters was significantly positively correlated with the Mini-Mental State Examination (MMSE) scores and significantly negatively correlated with Functional Assessment Questionnaire (FAQ) scores and global Clinical Dementia Rating (CDR) scores in the patient groups. Significant correlations were also found between the PE and regional homogeneity (ReHo) in the patient groups. These results indicated that declines in PE might be related to changes in regional functional homogeneity in AD. These findings suggested that complexity analyses using PE in rs-fMRI signals can provide important information about the fMRI characteristics of cognitive impairments in MCI and AD.
BackgroundWith the increasing of ageing population, tuberculosis in the elderly brings a challenge for the tuberculosis (TB) control in China. Enough social support can promote the treatment adherence and outcome of the elderly patients with TB. Exploring effective interventions to improve the social support of patients is of great significance for TB management and control.MethodsA community-based, repeated measurement trial was conducted. Patients with TB >65 years of age were allocated into the intervention or control group. Patients in the intervention group received comprehensive social support interventions, while those in the control group received health education alone. The social support level of patients was measured at baseline and at the first, third and sixth months during the intervention to assess the effectiveness of comprehensive social support interventions.ResultsA total of 201 patients were recruited into the study. Compared with the control group, social support for patients in the intervention group increased significantly over time (βgroup*time=0.61, P<0.01) in the following three dimensions: objective support (βgroup*time=0.15, P<0.05), subjective support (βgroup*time=0.32, P<0.05) and support utilisation (βgroup*time=0.16, P<0.05). The change in the scores in the control group was not statistically significant.ConclusionsThe intervention programme in communities, including health education, psychotherapy and family and community support interventions, can improve the social support for elderly patients with TB compared with single health education.Trial registration numberChiCTR-IOR-16009232
