Valproic acid (VPA) is a traditional broad-spectrum antiepileptic drug, but long-term use of VPA will increase the risk of adverse drug reactions, with metabolic syndrome being the most common and often leading to infertility in men. Therefore, it is crucial to explore the relationship between epilepsy, VPA, metabolic syndrome and reproduction, the underlying pathogenesis, risk factors, and therapeutic measures. This exploration is essential for preventing adverse drug reactions and for guiding safe and rational use of drugs in clinical practice. This article summarizes the incidence of drug-induced metabolic syndrome and infertility in men with epilepsy who are treated with oral VPA, aiming to provide new research insights for optimizing treatment and reducing drug side effects.

Attention impairment in temporal lobe epilepsy (TLE) leads to other advanced cognitive impairments, such as memory and emotional recognition. Moreover, the severity of attention impairment determine the differences in strategies for preventing sudden unexpected death in epilepsy (SUDEP). Factors such as abnormal brain electrical discharges, sleep, and antiepileptic drugs are all associated with attention impairment. Neuroelectrophysiological observations have shown that abnormal electrical discharges interfere with the synchronization of cortical oscillations, and preventing the spread of abnormal epileptic discharges to subcortical activation structures helps reduce attention disorders. Neuroimaging reveals damage to the gray matter and white matter of the brain related to attention and poor connectivity of the whole-brain network. Therefore, early identification of attention impairment in TLE patients has become even more important. Treatment of attention impairment includes supplementing attention-related neurotransmitters, cognitive-behavioral therapy, surgical procedures, and neuromodulation techniques. This article mainly reviews the characteristics of attention impairment in TLE patients from the perspectives of clinical behavior, pathophysiology, and treatment, aiming to provide new insights for the early identification and management of attention impairment in TLE patients.

BACKGROUND:In recent years, the technical parameters about hurdle athletes are mainly obtained through video analysis and DLT algorithm. However, the gait and surface electromyography (sEMG) characteristics during normal walking are little reported. OBJECTIVE: To explore the changes of the gait and lower limb sEMG signals relative to gait period in hurdle athletes. METHODS:Eight male professional hurdlers were selected to perform gait and lower limb sEMG tests on the trail, and the differences in gait and sEMG signals were analyzed by mathematical statistics. RESULTS AND CONCLUSION: The gait parameters of hurdlers showed no significant differences (except step length). In the total gait cycle, along with the gait changing, the right and left side muscles of the same name moved alternately. The median frequency and average power frequency of the tapping leg in the lower limb muscles were greater than those of the swinging leg (except biceps femoris, tibialis anterior and lateral gastrocnemius), but the mean EMG and EMG integral values of the tapping leg were smaller than those of the swinging leg. At the stand phase, the median frequency and average power frequency of the tapping leg in the lower limb muscles were greater than those of the swinging leg (except tibialis anterior), but the mean EMG and EMG integral values of the tapping leg were smaller than those of the swinging leg (except soleus). At the swing phase, the median frequency and average power frequency of the tapping leg in the lower limb muscles were greater than those of the swinging leg (except tibialis anterior and lateral gastrocnemius), but the mean EMG and EMG integral values of the tapping leg were smaller than those of the swinging leg (except soleus). To conclude, there are different degrees of differences in the frequency domain and time domain of the lower limb muscles between tapping and swinging legs. Additionally, the muscle strength of the tapping leg is less than that of the swinging leg.

Objective To describe the prevalence and change of rationing of nursing care (RNC) in medical and surgical units of level 2 and level 3 general hospitals across Guangdong province. Methods RNC were measured by asking nurses about the completion status of 12 necessary nursing care activities, and the prevalence of RNC in 2014 was compared with the study results from the China Hospital Nursing Workforce Research(CNWR) in 2009 (exclusively using the data of Guangdong province) to describe the change of RNC. Results Six activities were rationed averagely in 2014, and the most frequent activities rationed wereComfort/talk with patients accounted for 69.8% (975/1 396) andEducating patients and familiesaccounted for 67.3%(940/1 396). According to the CNWR in 2009, the average number of nursing care activities rationed was 3 which was statistically lower than the number in 2014 (P < 0.01). Conclusions RNC is prevalent in level 2 and level 3 general hospitals across Guangdong province, especially psychosocial care to the patients; the prevalence of RNC has not decreased since 2009.

Objective To explore the influencing factors of job burnout among nurses in level 2 and level 3 hospitals in Guangdong province. Methods A total of 2 066 first line nurses from 133 medical, surgical and intensive care units (ICU) of 23 level 2 and level 3 hospitals in Guangdong province were surveyed employing the questionnaire Hospital Nursing Human Resources Research during December 2013 to August 2014. Results In the multivariate logistic regression models, each additional doctor per nurse was associated with 1.34 times increase in the likelihood of high level of emotional exhaustion(EE). Nurses had a 57.4%higher risk of high level of EE when they worked overtime. Every one point increase in ancillary service score, and every one more year working as a nurse was associated with 5.4%, 2.3%increase in the likelihood of high level of EE, respectively. Nurses were 42.1%,40.9%more likely to exhibit high level of depersonalization(DP) when they worked in medical units or hospitals of level 3, compared with nurses of surgical units and hospitals of level 2. Nurses had a 29.5%higher risk of high level of DP when they worked overtime. Nurses holding higher positions had a lower likelihood(37.7%) of high level of reduced personal accomplishment(PA) compared with nurses holding lower positions. Nurses in medical units or ICUs had a 31.2%, 51.6%higher risk of high level of PA than nurses in surgical units, respectively. Conclusions Job burnout of nurses is at a quite high level in level 2 and level 3 hospitals in Guangdong province. The probability of the occurrence of burnout is related to the hospital, unit and nurse characteristics and nursing workloads.

Triptolide (TL) is a major active component extracted from Chinese traditional herb Tripteryginm wil-fordii Hook. In this article, the effects of TL on mixed lymphocyte culture (MLC),suppressor T cell(Ts) activity, delayed type hypersensitivity (DTH) reaction, IL - 2 secretion activity and Th/Ts ratio were evaluated, In vitro TL 0. 5~10 ?g ? L-1suppressed one-way MLC,Lymphocytes induced in first MLC with TL of 5,10 ?g ? L-1 suppressed the second MLC after irradiation with 3000 rad 60Co source. This suggests that TL may induce Ts cell-s. In vivo, DTH reaction sensitized to dinitrofluo-robenzene (DNFB) monitored by the increase in weight of the ears challenged with antigen was suppressed by TL at doses of 0. 12 to 0. 50 mg ? kg-1(ip,qd?5) and the IL -2 activity secreted by spleen cells of these mice was inhibited at doses of 0. 25 and 0. 5 mg ? kg-1. TL 0. 25, 0. 5 mg ? kg-1(ip,qd?8) also had prominent suppres-sive effects on enhanced DTH reaction which was induced by cyclophosphamide(250 mg ? kg-1,ip). Th/Ts ratio of mouse thymus cells were reduced after given 0. 25 mg ? kg-1 of TL for 5 consecutive days. The above-mentioned data suggest that TL has suppressive effects on cellular immunity function and the suppressive mechanism may be related to the suppression of Th cells and IL-2 secretion activity and the induction of Ts cells.
