Colonoscopy has been accepted as the standard method for evaluation of colon and rectum,its success rate depends on the quality of bowel preparation. Aims:To evaluate the cleanliness and tolerance of fractionated dose versus single dose polyethylene glycol electrolyte solution( PEG-ES) bowel preparation regimens for colonoscopy. Methods:A total of 427 consecutive asymptomatic individuals undergoing colorectal cancer screening were enrolled and randomly assigned into 2 groups. Subjects in group A drank 1. 5 L PEG-ES on the eve and 4 hours before colonoscopy, respectively;subjects in group B received a single dose of 3 L PEG-ES 5 hours before colonoscopy. Score and degree of Boston bowel preparation scale(BBPS)and PEG-ES related adverse effects of the two groups were assessed and compared. Results:There were no significant differences in gender,age and cecal insertion rate between group A and group B(P ﹥ 0. 05). Score of BBPS was significantly higher in group A than in group B(P ﹤0. 01). Both regimens met the requirement of conventional colonoscopy,however,the cleanliness of colon was graded as excellent in more subjects of group A( P ﹤ 0. 01),and less subjects of group A complained PEG-ES related nausea(P ﹤0. 05). Logistic regression analysis revealed that the PEG-ES drinking pattern was associated with cleanliness of colon and occurrence of nausea( P ﹤ 0. 05). Conclusions:Fractionated dose PEG-ES regimen provides a better colonic cleansing quality and tolerance for bowel preparation of colonoscopy,which is superior to that of single dose regimen.

Objective To observe the effect of electroacupuncture at the beginning and ending points of bicipital muscle on the superficial electromyography (sEMG) of the spastic limb in hemiplegia.Method Forty patients with spastic hemiplegia after cerebral stroke were divided by the random number table into a group of electroacupuncture at the beginning and ending points (group A) and a group of electroacupuncture at antagonistic muscles (group B). The former selected Ashi points at the beginning and ending points of bicipital muscle, while the latter selected points at the antagonistic muscles [Tianjing (TE10), Qinglingyuan (TE11), etc.], to receive perpendicular puncturing. The needles were retained for 30 min, and the sEMG of bicipital muscles in resting state was detected after the removal of the needles. The spastic bicipital muscle was examined by sEMG prior to the acupuncture treatment, and respectively after 2-week and 4-week acupuncture treatment, and the detected parameters included root mean square (RMS) and integrated electromyography (IEMG).ResultThe EMG and IEMG declined gradually in the two groups after the acupuncture treatment; the intra-group comparisons of the RMS and IEMG values at three time points, e.g. prior to acupuncture treatment, after 2-week acupuncture treatment and after 4-weekacupuncture treatment, showed that the values changed significantly compared to those at the previous time point (P<0.05); the between-group comparisons showed that there were no significant differences in comparing the RMS and IEMG values regardless of different time points (P>0.05). The RMS and IEMG values presented same changing tendencies after 4-week acupuncture treatment in the two groups.ConclusionAcupuncture at the beginning and ending points and at the points on antagonistic muscles both can decrease the resting-state muscle tension in hemiplegia patients; sEMG is of certain significance in evaluating the treatment of hemiplegia.

A new method of automatic detection of brain lesion based on wavelet feature vector of CT images has been proposed in the present paper. Firstly, we created training samples by manually segmenting normal CT images into gray matter, white matter and cerebrospinal fluid sub images. Then, we obtained the cluster centers using FCM clustering algorithm. When detecting lesions, the CT images to be detected was automatically segmented into sub images, with a certain degree of over-segmenting allowed under the premise of ensuring accuracy as much as possible. Then we extended these sub images and extracted the features to compute the distances with the cluster centers and to determine whether they belonged to the three kinds of normal samples, or, otherwise, belonged to lesions. The proposed method was verified by experiments.

In this paper an approach of time-window complexity sequence is applied to sleep EEG analysis. This approach can reduce the loss of state information due to the nonstationarity of EEG signal and the unevenness of state space, and can overcome certain limitations of the complexity itself to some extent. It will help to extract the state features of EEG in different sleep stages. In addition, we preprocess EEG by adopting ICA and wavelet transform (WT). The results show that some physiological artifact in EEG can be eliminated effectively by these methods, and the sleep staging based on sleep EEG data will be more exact.

Objective: To understand the current status of follow up of people living with HIV/AIDS by health service at grass root in rural area of Jiangxi province and related factors, and provide references for the promotion of the follow up by grass root health service. Methods: People living HIV/AIDS aged ≥18 years and diagnosed before 31 December 2017 in 6 townships of Xinjian, Yushan counties and Guixi city were included in the study in Jiangxi province. They had been followed up for more than one time after the first epidemiologic survey. The information about their demographic characteristics and HIV infection status were collected by using self-designed questionnaire. Univariate and multivariate logistic regression analyses were conducted to identify the factors that influencing the acceptance of follow up by grass root health service. Results: Of the 373 surveyed HIV infected subjects aged (53.06±16.15) years, 261 were males (70.0%, 261/373). Among the surveyed subjects, the illiteracy and people who received only primary school education accounted for 54.7% (204/373). The rate of follow up of the HIV infected subjects by grass root health service was 55.8% (208/373), and those through heterosexual contact were 58.5% (190/325). The multivariate regression analysis showed that the acceptance of follow up by grass root health service was higher in those who were farmers (OR=7.36, 95%CI: 2.52-21.45), had family support (OR=16.01, 95%CI: 2.25-49.73), didn’t worry about discrimination (OR=12.97, 95%CI: 4.75-35.42), trusted health care provider (OR=5.07, 95%CI: 2.19-11.76) and showed AIDS symptoms (OR=10.58, 95%CI: 2.25- 49.73). Conclusions The performance of follow up of people living with HIV/AIDS by grass root health service was well, suggesting it is a feasible management model. Being famer or not, family member supporting or not, worry about discrimination or not, trusting health care provider or not and showing AIDS symptoms or not were the main factors influencing the acceptance of follow up by grass root health service.

The HIV-infected people were investigated for their satisfactory situation towards the follow-up management of primary medical and health care institutions in Xinjian County, Yushan County and Guixi City of Jiangxi Province from January to July 2018 and related factors were also analyzed. The total score of the Infected Patients′ Follow-up Management Satisfaction Scale higher than 59 was defined as the satisfactory. 75.68% of 259 infected patients were satisfied with the follow-up management. Compared to farmers and other follow-up modes, non-farmers (OR=10.72, 95%CI: 2.07-55.63), and patients receiving follow-up service in responsible institutions (OR=6.44, 95%CI: 3.12-13.30) were more satisfied with follow-up management.
