Objective To investigate the current status of medication compliance of patients with anky-losing spondylifis and analyze its related factors. Methods Seventy-four patients with ankylosing spondylitis were investigated about their general conditions,medication compliance and its related factors.The results were analyzed. Results Thirty-nine patients(52.7%) had good medication compliance while the rest 35 cases has poor medication compliance among which 24 patients with drug withdrawal exceeded 1 month.The medication compliance for patients with disease process of lower than 0.5 year,0.5 to 1.0 year,1 to 2 years and above 2 years was 82.0%,60.0%,25.0%and 31.0%.The logistic regression analysis showed that the disease process,dis-ease knowledge and media advertisement were the main influencing factor for medication compliance,while the age,sex,marital status,education background,adverse reaction,satisfaction degree with medication effect, economic conditions and depression were not major influencing factors. Conclusions About half of patients with anky-losing spondylitis had poor medication compliance,especialy with disease process of above 1 year.The main in-fluencing factors include disease process,disease knowledge and media advertisement.

OBJECTIVETo identify the correlation of the volume of residual urine (VRU) with the severity of bladder outlet obstruction (BOO) and detrusor contractility in patients with benign prostatic hyperplasia (BPH).

METHODSA total of 152 patients with clinically diagnosed BPH underwent ultrasonography for measurement of the prostate volume and RVU, free uroflowmetry, and urodynamic examination for the severity of BOO and detrusor contractility. Using the software SPSS20. 0, we analyzed the correlation between the ultrasonographic results and urodynamic parameters and compared the two sample means by the t-test.

RESULTSThe prostate volume was correlated positively with BOO severity (r = 0.432, P < 0.01) and detrusor contractility (r = 0.343 , P < 0.01) while Qmax negatively with BOO severity (r = 0.327, P < 0.01) but not significantly with detrusor contractility (r = 0.123, P > 0.05). VRU showed a significantly negative correlation with detrusor contractility when > 150 ml (r = -0.490, P < 0.01), even more significantly when > 300 ml (r = -0.717, P < 0.01), but exhibited no significant correlation with it when ≤ 150 ml (r = 0.041, P > 0.05).

CONCLUSIONVRU can somehow predict the detrusor function. For patients with VRU > 150 ml, especially for those with VRU > 300 ml, the detrusor function should be evaluated and urodynamic examination is recommended for exact assessment of BOO severity and detrusor contractility.

Objective To study effectiveness of System intervention to occupation burnout of medical staff.Methods Specimens were classified as interventional group and control group by 1:1 partnership rule.Systemic intervention,which came from organization,family and individual,was only applied to interventional group.The objective was to establish requirement and resource mechanism,continually increase response resource,and improve matching state of individual & job.It allowed full play to the first grade prevention(development intervention),the second grade prevention(symptom intervention)and the third grade prevention(burnout intervention).It determined effectiveness of intervention via indexes of occupation burnout,mental health and satisfaction within group or internal groups.Results Before systemic intervention,there was no significant difference between intervention group and control group(P＞0.05).After systemic intervention,the scores of burnout(emotion exhaustion(17.54±9.97)vs(14.30±11.87),P＜0.01;depersonalization(5.29±5.01)vs(4.63±5.65),P＜0.05;low personal accomplishment(6.47±4.89),(5.61±5.10),P＜0.01),check list-90(SCL-90),personal satisfaction in intervention group showed apparent difference compared with that in control group.But there was no significant difference in control group before and after intervention.Conclusion On the whole systemic intervention to health care staff obtains obvious achievement,effectively reduces emotional exhaustion,obsessive symptom and terror emotion,and enhances individual satisfaction.

AIM: To explore the effect and possible mechanism of type 2 innate lymphoid cell (ILC2) on the development of chronic renal failure (CRF).METHODS: The patients with chronic renal failure (n=36) in the Fist Affiliated Hospital of Sun Yat-sen University from March 2016 to December 2016 were selected, and 32 healthy persons in the same period were enrolled in the study for control.The proportion of ILC2 in the PBMC of CRF patients and healthy controls was detected by flow cytometry, IL-13 concentration in the plasma was measured by ELISA.The isolated PBMCs from the patients and healthy persons were divided into 3 groups (control group, cytokine group, intervention group) and cultured in vitro for 3 days, respespestively, then IL-13 concentration was measured by ELISA.The protein levels of phosphorylated signal transducers and activators of transcription 6 (p-STAT6) in the PBMC of healthy controls before stimulation and after stimulation for 15 min, 30 min, 1 h, 2 h were determined by Western blot.RESULTS: The proportion of ILC2 in the PBMC and the plasma IL-13 concentration of CRF patients was higher than that in the healthy controls (P<0.05).In the culture supernatant in vitro, IL-13 concentration in the 3 subgroups of CRF patients (control group, cytokine group, intervention group) were all higher than that in the healthy controls (P<0.05), both the 2 groups showed a trend that the active IL-13 concentration in cytokine group was higher than that in control group, and that in intervention group was lower than that in cytokine group.The protein levels of p-STAT6 in cytokine stimulated-PBMC with a time dependent manner.CONCLUSION: The percentage of ILC2 in the PBMC is elevated in CRF patients.Furthermore, the ILC2 secret large amount of IL-13 to mediate the polarization of Th2 cells to regulate immunity through activating p-STAT6.

Objective To establish the cardiac arrest-cardiopulmonary resuscitation model in rats, and to observe the effect of mild hypothermia on autophagy in hippocampal CA1 neurons after ROSC.Methods A total of 36 Wistar rats were randomly divided into two groups: normal temperature treatment group(NT group) and mild hypothermia treatment group(HT group).To establish the cardiac arrest-cardiopulmonary resuscitation(CA-CPR) model in rats by epicardial electrical stimulation induced ventricular fibrillation, and to sacrifice 3 animals in each group to obtain the brain cortex in 2nd and 4th hours after ROSC in order to observe the expression of p-AMPK by electron microscope and LC3 granules through Western blot.The neurological deficit score(NDS) was assessed in 24、48、72 hours respectively after ROSC.To sacrifice the animals so as to take the cerebrum in 72 hours after ROSC, then calculate the apoptotic index of the hippocampal CA1 neurons, which were dyed through TUNEL method.Results The expression of p-AMPK、Beclin-1 and LC3-Ⅱ/LC3-Ⅰratio in Normothermia group were all lower than the Mild hypothermia group(P<0.05), the neurons plasma of hippocampal CA1 area in the Hypothermia group demonstrated obvious LC3 granules formation, the NDS score of the Normothermia group and the Mild hypothermia group in ROSC24h、ROSC48h、ROSC72h were 320vs205、285vs140、266vs120, respectively.The apoptotic index of the hippocampal CA1 area in the Normothemia group in ROSC72h was higher than the Mild hypothermia group,(P<0.05).Conclusions Mild hypothermia after cardiopulmonary resuscitation promotes autophagy of the hippocampal CA1 area neurons in rats and reduce neuronal apoptosis.

OBJECTIVETo determine whether testosterone-induced intra-testicular testosterone withdrawal and therefore spermatogenic impairment is associated with looser arrangement of spermatogenic cells in rats.

METHODSAdult male SD rats received intramuscular injection of testosterone undecanoate at 19 mg/(kg x 15 d) for 130 days, and then testicular tissue blocks were obtained for the preparation of methacrylate resin-embedded sections and observation of the changes in testicular histology.

RESULTSApart from such changes as impaired spermiogenesis and spermiation, apparently looser arrangement of spermatogenic cells was seen in 11.5% of the seminiferous tubule profiles, with radial cracks (empty spaces) running towards the tubule lumen being formed between lines, bundles or groups of spermatogenic cells (mainly spermatids and spermatocytes).

CONCLUSIONLooser arrangement of spermatogenic cells is one of the key histological changes resulting from intra-testicular testosterone withdrawal in rats.

Objective To investigate the map and pattern of blood oxygen level dependent(BOLD)signal changes correlated to interictal epileptiform discharges(IEDs)with EEG-fMRI in patients with partial epilepsy and then to explore the pathophysiological mechanisms of epileptic discharges and their effect on brain function in partial epilepsy.Methods Through the method of EEG-fMRI,2 patients with parial epilepsy were studied.The relationship between the regions of BOLD signal changes linked to IEDs and the electroelinical localization of epileptogenic zone in patients with partial epilepsy were investigated.Results The epileptogenic areas localized by electroclinical findings in the 2 patients all showed maximal activation and 2 sites of significant activation were found in 1 of the 2 patients;Weak activation were also manifested in the opposite side corresponding to lesions.Conclusions IED-linked BOLD response in patients with partial epilepsy is mainly in epileptogenic zones and weak activation can also be seen in the corresponding contralateral areas of epileptogenic zoiles.Activation areas ale well concordant with epileptogenie areas localized by electroclinical findings.

Objective To explore the change of serum insulin-like growth factor-2 (IGF-2) and its relationship with clinical characteristics in patients with schizophrenia. Methods Fifty-one schizophrenic patients were recruited in the present study and 50 healthy volunteers served as controls. The serum IGF-2 level was measured using enzyme linked immunosorbent assay (ELISA). Positive and Negative Syndrome Scale (PANSS) was used to evaluate the psychotic symp?toms of patients. Trail Making Test-A (TMTA), Digit-Symbol Coding Test (DSCT), Continuous Performance Test (CPT) and Stroop Color-Word Test (SCWT) were used to evaluate the cognitive function of both groups. Results There were sig?nificant differences in the results of TMTA, DSCT, CPT and SCWT between patient and control groups. The serum levels of IGF-2 were significantly lower in patients than that in controls [(202.7±40.7) ng/mL vs. (365.9±65.5) ng/mL, P<0.01]. The levels of serum IGF-2 were not significantly different between first-episode and recurrent schizophrenic patients (P>0.05). Furthermore, significant correlations were found between the serum IGF-2 level and the negative symptom sub?scale of PANSS (r=-0.397, P=0.004), CPT score (r=0.378, P=0.006), SCWT-word number (r=0.289, P=0.040), SC? WT-color number (r=0.327, P=0.019) and SCWT-word/color number (r=0.386, P=0.005) in schizophrenic patients. Con?clusion The serum IGF-2 levels of patients with schizophrenia are significantly lower than that of healthy controls, and the IGF-2 level is associated with the severity of negative symptoms and cognitive impairments in patients, indicating that serum IGF-2 might be an indicator of the severity of schizophrenia.
