ABSTRACT
Purpose@#This study aimed to explore the impact of ABL1–tyrosine kinase inhibitors (TKIs) adherence on the survival of chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) children and clarify the potential predictors of patients’ prognosis from TKIs intake practices. @*Materials and Methods@#Ninety newly diagnosed Ph+ ALL patients who received TKIs were enrolled. We collected the baseline characteristics and adverse events in all children; moreover, TKIs adherence was measured by an eight-item Morisky medication adherence scale (MMAS-8). Progression-free survival (PFS) and overall survival (OS) analysis were performed, and risk factors for PFS and OS were evaluated. @*Results@#Among all patients, 69 cases were regarded as adherers, while 21 were non-adherers. The median duration of TKIs interruption was significantly prolonged in the non-adherence group than in the adherence group (13 [0-101] vs. 56 [11-128], p < 0.001). Additionally, dose reduction occurred in 55.2% of non-adherers versus 23.0% of adherers (p=0.002). The PFS and OS in adherers were significantly higher versus non-adherers (p=0.020 and p=0.039). MMAS-8 score was an independent risk factor for PFS (p=0.010) and OS (p=0.031). Among non-adherers, the median OS was only 23.1% (4.2%-42%) in patients aged ≤ 10 years versus 54.4% (38.8%-70%) in adolescents. Most of the patients who experienced TKIs non-adherence suffered pancytopenia. @*Conclusion@#TKIs adherence during treatment significantly influenced the survival of pediatric Ph+ ALL patients, and non-adherers with age ≤ 10 years were more vulnerable to TKIs disruption. The cumulative TKIs dose should be especially emphasized to patients with age ≤ 10 years, which may result in an inferior achievement of relevant treatment milestones.
ABSTRACT
Objective To observe the effects of electroacupuncture on the learning and memory ability and cerebral cortex inflammatory factor of rats with vascular cognitive impairment (VCI); To discuss the mechanism of electroacupuncture for preventing and treating VCI. Methods VCI rat models were made in microemboli injection through internal carotid artery method. The successful modeled rats were randomly divided into model group, positive medicine group and electroacupuncture group, and normal rats were taken as control group. Three days after rat models were established, the positive medicine group was given donepezil hydrochlorideby gavage, and electroacupuncture group was given electroacupuncture at "Baihui" and "Zusanli" acupoints. After treatment, the learning and memory ability was detected by Morris water maze test. The contents of TNF-α, IL-6 and IL-1β in rat brain tissue were detected by ELISA. Results The water maze results showed that with the increase of the number of training, the average escape latency of rats to find platform in positive medicine group and electroacupuncture group all had different degrees of shortening in positioning cruise experiment; in space exploration experiment, positive medicine group and electroacupuncture group to cross the platform area for the first time were significantly reduced compared with the model group; compared with the control group, the contents of TNF-α, IL-6 and IL-1β in the model group were increased significantly; compared with the model group, the contents of TNF-α, IL-6 and IL-β in postive medicine group and electroacupuncture group were decreased. Conclusion Electroacupuncture at "Baihui"and "Zusanli" acupoints can decrease the contents of TNF-α, IL-1 and IL-6 in the cortex of VCI rats, and improve the learning and memory ability of rats.
ABSTRACT
Objective: To investigate the hospital employee satisfaction and trustworthiness in the background of the trusteeship mode and to find out the problems after trusteeship.Methods: Minnesota satisfaction questionnaire (MSQ) and the self-made questionnaire were used to conduct the survey.Results: The overall employee satisfaction (3.80±0.86) and trustworthiness (3.95±0.77)were higher.The highest level of trustworthiness concerned the cultural connotation (84.8%) followed by the management concept (82.8%) for overall satisfaction.The lowest level of employee satisfaction concerned income and workload (53.7%), followed by the working conditions and environment (55.3%).The administrative staff satisfaction was higher compared to that of medical staff (p=0.001), which showed significant statistical differences.Conclusions: The hospital has made some achievements after the trusteeship system reform, however, it still needs improvement and further strengthening in many aspects.The hospital must always keep abreast of the demands of workforce and improve the staff satisfaction so as to promote its continuous and sustainable development.

ABSTRACT
Objective]To discuss the effect of sciatic nerve injury on the expressions of tumor necrosis factor-alpha(TNF-α), interleukin-1β(IL-1β)and interleukin-10(IL-10)in anterior cingulate cortex(ACC),and further to explain their roles resided in the development of neuropathic pain.[Method]With use of the methods of behavioral test,western blot and immunohistochemistry, we examine the effects of spared sciatic nerve injury(SNI)on the expressions of TNF-α,IL-1β,and IL-10 in ACC,and observe the effect of the neutralizing antibody of TNF-α,IL-1β on the rat mechanical allodynia.[Result]In present experiment ,SNI increased the protein levels of TNF-α,IL-10,but not IL-1β in ACC. Increased TNF-α-IR and IL-10-IR in ACC is located in neurons ,but not astrocytes and microglia at 7 d following L5-VRT. Pre-treatment with anti-TNFα antibody but not anti-IL-1βantibody into ACC significantly increased the rat paw withdrawal threshold to von Frey hairs.[Conclusion]These data suggested that the increased TNF-αin ACC neurons might be responsible for the development of neuropathic pain.
ABSTRACT
BACKGROUND/AIMS: A large number of studies have shown that function constipation (FC) has an extremely high incidence of mental and psychological disorders. Cranial electrotherapy stimulation (CES) was applied to the treatment of psychological disorders such as anxiety and depression. We explored the effects of CES combined with biofeedback therapy (BFT) on the psychological state, clinical symptoms, and anorectal function in patients with FC. METHODS: A total of 74 patients with FC were randomly divided into 2 groups. The control group received BFT. CES combined with BFT was carried out in the experiment group. All patients were assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Wexner constipation score at baseline and the end of each course. Anorectal manometry and balloon expulsion tests were performed before and after treatment. RESULTS: After treatment, the participants in the experiment group had significantly lower score SAS, SDS, and Wexner constipation scores than the control group (all P < 0.05). The number of successful expulsion in the experiment group was larger than the control group (P = 0.016). CONCLUSIONS: CES combined with BFT was effective in improving the psychological status of anxiety, depression, and bowel symptoms in patients with FC.

The purpose of this work was to study the characteristics of rat brain abnormalities at two hemispheres at the early stage of electrogenic epilepsy. Experiments were performed on 37 male Sprague-Dawley rats. Chronically repetitive tetanization (60 Hz, 2 s, 0.4 - 0.6 mA) was used to stimulate the right dorsal hippocampus (DHPC) of the rat brain once a day for 2, 4, 6, 8 or 10 d, respectively. The T(2) weighted magnetic resonance image (T(2)-WI) were obtained from each experimental rat at the end of the experiments. Histological sections were obtained after experimentation. The results showed that the main pathologic changes at the early stage of epilepsy included: (1) T(2)-WI hyperintensification, the histological enlargement of lateral ventricle (LV) and pathological hyperplasia of ventricular choroidea plexus occurred. The pathological hyperplasia was symmetric in two hemispheres, but the LV enlargement was not. (2) Histologically enlarged LV area showed a resemblance to T(2)-WI hyperintensive area. Compared with the control rats, large T(2)-WI hyperintensive area (P=0.0259; P=0.0184; P=0.0184; P=0.0404; P=0.0259) and histologically enlarged LV area (P=0.0210; P=0.01; P=0.0100; P=0.0152) were present in chronically tetanized rats. (3) Dynamic characteristics of histologically enlarged LV area resembled to those of T(2)-WI hyperintensity area in chronically tetanized rats at different stimulating day. Lateralization of T(2)-WI hyperintensity was in accordance with that of T(2)-WI abnormal area and of histologically enlarged LV. These abnormalities were severe on the contralateral side on the stimulating day 6, or on the ipsilateral side on the stimulating day 10. These results imply characteristic propagation of brain abnormalities crossing to the opposite hemisphere at the early stage of an electrogenic rat epilepsy.

The purpose of the present study was to investigate the features of pathophysiological neural networks in rat temporal lobe epileptogenesis. To establish electrogenic epilepsy model, repetitive tetanization (60 Hz, 2 s, 0.4-0.6 mA) was delivered into the right dorsal hippocampus (HPC) of rat brain. Rats were divided into different groups. Experimental animals received tetanic stimulation once a day for 2, 4, 6, 8 or 10 days, respectively. Primary wet dog shakes (WEDS) of the animals were recorded daily during the stimulation to understand the development of behavioral seizures at early stage of epilepsy. The T(2)-weighted (T(2)-WI) spin-echo images were obtained from each experimental rat. The results demonstrated that T(2)-WI hyperintensity of experimental rats was observed in bilateral symmetric dorsal lateral ventricle (LV) areas at stimulating day 2 (n=4), in contralateral medial and ventral LV areas to the side of the electrode at stimulating day 6 (n=5), in contralateral ventral LV areas at stimulating day 8 (n=3), and in ipsilateral ventral LV areas at stimulating day 10 (n=4). Therefore the peak rate of primary WEDS appeared on stimulating day 4 in the experimental rats. Morphological identification demonstrated that the T(2)-WI signal abnormalities were related to the enlarged LV and pathological ventricular choroidea plexus hyperplasia. The results suggest that the development of rat brain abnormalities from dorsal LV to ventral LV at early stage of epilepsy can be measured by magnetic resonance image, which implies reorganization of pathophysiologically functional networks before kindling effect appear.
