Objective To compare the efficacy and safety of olanzapine and risperidone in treatment of treatment-resistant schizophrenia.Methods A total of 68 patients with treatment-resistant schizophrenia were randomly assigned to olanzapine group and risperidone group, and received olanzapine or risperidone treatment for 12 weeks respectively.The efficacy and adverse events were assessed with the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression Scale (CGI) and Treatment Emergent Symptom Scale(TESS) at week 0 and 1,2,4,8,12.Results The PANSS scores in both groups decreased significantly after treatment (P 0.05).The response rate was higher in olanzapine group than risperidone group ( P 0.05), with olanzapine being associated with more weight gain, and risperidone with more akathisia, abnormal lactation and/or menostasia,hypermyotonia.Conclusion The results suggest olanzapine be of good efficacy and less side effects in the treatment of treatment-resistant schizophrenia in comparison with risperidone.

Background/Aims: Gastric neuroendocrine tumors (G-NETs) are uncommon neoplasms that can present with or without clinical symptoms. In this study, we evaluated the incidence, prognosis, and temporal trends of G-NETs. Methods: We analyzed all cases of G-NETs registered in the Surveillance, Epidemiology, and End Results (SEER) database from 1973 to 2014. Incidence was estimated by age and joinpoint analyses. Survival rates were calculated and survival trends over time were evaluated. Results: A total of 3740 eligible patients were enrolled in the study. G-NETs incidence increased from 0.31 per 1 000 000 patients in 1975 to 4.85 in 2014, with an annual percentage changes (APCs) of 8.9% (95% confidence interval [CI] = 7.7% to 10.21%, P < 0.001, t test (29) from 1975 to 2001 and 3.6% from 2002 to 2014 (95% CI= 2.3% to 4.9%, P < 0.001). For cases diagnosed between 1973 and 1982, five-year survival was 62.8% ± 7.0% (Standard error, SE) and increased to 86.7% ± 0.7% for cases diagnosed between 2003 and 2012 (P < 0.001). Years of diagnosis, gender, age at diagnosis, marital status, grade, tumor size, tumor stage, and surgery performed or not were the strongest predictors of worse survival in both univariate and multivariate analysis (P<0.05). Conclusion: G-NETs are uncommon neoplasms but the incidence is growing. Survival has improved in the past decades. Years of diagnosis, gender, age at diagnosis, marital status, grade, tumor size, tumor stage, and surgery status predict survival in patients with G-NETs.
Our previous study indicated that thimerosal is one of the most effective artificial activators to mimic sperm-induced increases in the intracellular free calcium concentration ([Ca2+]i) and other activation events in pig oocytes (Macháty et al., 1997). The present study was conducted to examine the temporal relationship between intracellular calcium transients, cortical granule (CG) exocytosis and the zona reaction induced by thimerosal. When pig oocytes matured in vitro were exposed to 200 μM thimerosal the first intracellular calcium transient, with a mean peak ratio of 4.97 ± 1.14, was observed 509.64 ± 122.03 s after addition of thimerosal. The density of CGs fell significantly from 63.3 ± 11.7 CGs/100 μm2 of cortex in control oocytes to 25.7 ± 19.2 CGs/100 μm2 of cortex (59.4% release) at 2 min after the first intracellular calcium transient. At 5 min after the calcium transient the residual CG density had been reduced to 10.7 ± 10.4 CGs/100 μm2 of cortex (83.1% release). This degree of CG exocytosis was the same as that in oocytes penetrated by sperm (9.5 ± 5.1 CGs/100 μm2 of cortex). No further decrease in residual CG density was observed at 10 min (10.3 ± 14.8 CGs/100 μm2 of cortex). Whereas 77.4% (120/155) of control oocytes were penetrated by spermatozoa only 1.4% (2/144) of thimerosal-treated oocytes were penetrated. Further experimental results obtained by in vitro fertilisation of oocytes with preincubated (capacitated) spermatozoa suggested that the zona block to sperm penetration in thimerosal-treated oocytes occurred within 35 min after CG exocytosis and 40 min after the first calcium transient. These results indicate that polyspermic penetration of pig oocytes inseminated in vitro is not due to delayed or incomplete CG exocytosis but more likely to a delayed zona reaction and/or simultaneous sperm penetration.
Abstract The aim of this study was to evaluate long-term survival and risk factors associated with multidrug-resistant tuberculosis (MDR-TB) patient survival in Central China. Between December 2006 and June 2011, incident and retreatment adult MDR-TB patients were enrolled in the present study. Cox proportional hazard regression analysis was used to evaluate the risk factors affecting survival. The total follow-up period was 270 person-years (PY) for 356 MDR-TB cases in Wuhan. Of the 356 cases, 103 patients died, yielding an average case fatality rate of 381.2 per 1000 TB patients per year. Using adjusted Cox regression analysis, older age (adjusted hazard ratio (aHR) >3.0 starting from 30 years) and low education level (primary and middle school; aHR 1.67 (95% CI 1.01–2.77)) were independently associated with lower survival. Diabetes mellitus profoundly affected the survival of MDR-TB patients (aHR 1.95 (95% CI 1.30–2.93)). Our data demonstrate that coexistent diabetes significantly and negatively impacted MDR-TB patient survival. In addition, MDR-TB patients aged 60 years or older exhibited a greater risk of mortality during follow-up. Our findings emphasise that MDR-TB patients with comorbidities that increase their risk of death require additional medical interventions to reduce mortality.
Objective To investigate the correlationship between the degree of leukoaraiosis (LA) with intima media thickness of carotid (CAMIT) and high-sensitivity C-reactive protein (hs-CRP)in elderly patients.Methods Eighty-one elderly patients with LA were divided into three groups according to the degree of leukoaraiosis detected by magnetic resonance imaging (MRI),32 cases were in LA level 1 group,23 cases were in LA level 2 group,26 cases were in LA level 3 group.Thirty-two healthy elderly people without LA were in control group.The differences were compared between the four groups in FBG,CHOL,TG,LDL,HDL,UA,hs-CRP and CAIMT.Results The CAIMT of LA patients were significantly higher than those of control group (P ＜ 0.05),there was significant difference between LA 1 level group and 3 level group (P ＜ 0.05),the hs-CRP levels of LA level 1 group and level 2 group were significant different (P ＜ 0.05) with controls,there were significantly difference (P ＜ 0.05) between LA level 1 group and level 3 group.The correlation analysis showed CAIMT was positively correlated with hs-CRP (r =0.879,P ＜0.01).Conclusions hs-CRP and carotid atherosclerosis may play an important pole in the pathogenesis of LA,CAMIT and hs-CRP were closely correlated with the degree of leukoaraiosis.

The epidemic of coronavirus disease 2019 (COVID-19) broke out during the peak season of influenza in China. We aimed to assess the knowledge, attitudes, and practices (KAP) of influenza among Chinese adults during this special season. A cross-sectional online questionnaire survey was performed by recruiting 4822 participants. There were 76.09% of the participants reporting that they learned more knowledge of influenza during the COVID-19 epidemic. The mean knowledge score of participants was 5.51 ± 1.55 (78.7% correct rate), and participants who received influenza vaccination in the past year scored the highest (6.06 ± 1.30, p< .001). Nearly half of the participants (49.63%) agreed the threat to the functioning of society by influenza was far less than the COVID-19. 73.04% of the participants knew influenza vaccination was the most effective way to prevent influenza infection, while 54.18% did not know the vaccination location. The proportion of participants who were willing to get vaccinated would increase from 62.53% to 85.82% if clinicians recommended the vaccination. For influenza-like illness, merely 36.11% of participants would seek medical care from the hospital, and 60.53% agreed or showed a neutral attitude toward antibiotic use for influenza treatment. Regression analyses showed that the medical profession and history of influenza vaccination were both associated with higher knowledge or attitude score and participants' use of face masks in previous seasons and their willingness to receive influenza vaccination. In conclusion, the awareness of influenza vaccination among adults in China should be reinforced and educational campaigns were warranted to increase the coverage of influenza vaccination.
