Objective To evaluate the effects of pelvic autonomic nerve preservation (PANP) during the radical resection of rectal carcinoma on the sexual and urinary function of male patients.Methods The sexual and urinary dysfunction rates from 45 male patients who undergone PANP and 45 control patients who did not undergo PANP during radical resection of rectal carcinoma were analyzed.Results In the PANP group,the incidences of erectile dysfunction,ejaculatory dysfunction and urinary dysfunction were 26.67％,24.44％ and 28.89％,respectively.But in control group,the above three rates were 57.78％,60.00％ and 62.22％ in order.The rates of these three dysfunctions significantly were different between the two groups ( x2 =8.92,11.66,10.08,P ＜ 0.01 ).Conclusion PANP during radical resection of rectal carcinoma could reduce the post-operative sexual dysfunction and urinary dysfunction.

AIM:To evaluate the efficacy and safety of methazolamide in treating refractory uveitic macular edema.METHODS: Retrospective self-controlled study was designed.A total of 15 patients (20 eyes) with refractory uveitic macular edema which used methazolamide as adjuvant therapy were enrolled in Shanghai First People`s Hospital from January 2015 to June 2016.The changes of central macular thickness (CMT) and best corrected visual acuity (BCVA) were observed at baseline and 2, 4, 8wk after treatment.We also focused on the incidence of complications and relapse.RESULTS: The CMT was 445.95±154.10μm, 338.83±138.34μm, 251.50±40.20μm, 244.90±35.68μm at baseline, 2, 4 and 8wk after treatment, respectively.The differences among them were statistically significant (F=15.467, P<0.05).The BCVA (log MAR) were 0.40±0.17, 0.28±0.21, 0.19±0.20, 0.18±0.21 at baseline, 2, 4 and 8wk respectively, with a significant difference among them (F=5.208, P<0.05).When the cumulative dose reached to 700mg and 1400mg, no one had methazolamide-related complications;and when it came to 2800mg, 5 patients (33%) had methazolamide-related complication.After the withdrawal of methazolamide 1wk, 1 and 3mo, 3 patients (20%), 5 patients (33%) and 8 patients (53%) relapsed, respectively.CONCLUSION: Methazolamide is beneficial in improving macular edema and vision in 4wk.When the cumulative dose is more than 1400mg, we need pay attention to the complications.After discontinuing methazolamide for 1wk, macular edema relapsed in some patients, and more than half of patients recurred after 3mo.So the patients should be followed closely in 3mo after withdrawal of methazolamide.

5-lipoxygenase (5LO) is the key enzyme in the synthesis of leukotrienes, which are potent biological mediators of inflammation and anaphylaxis.After lock out of the 5LO gene by homologous recombination in embryonic stem cells, 5LO deficient-mice can develop normally and stay healthy, with a selective opposition to certain inflammatory insults. The cellular distribution of 5LO in unstimulated cells among different cell types is different; it can present in the cytosol, the nucleus, or both. 5LO was also found capable of shuttling in and out of the nucleus under certain conditions. It is suggested that 5LO might have other functions besides its traditional catalytic role.

Objective To discuss the neuropsychological mechanism of executive control for methadone maintenance patients(MMP).Methods Using the event-related potentials (ERPs) technique to reveal the time course of information processes with high temporal resolution,and exam the function of attention monitoring and response inhibition in heroin-dependent MMP.Results (l) The behavioral results: there were significant withinsubjects Stroop interference effects for the MMP and control groups (reaction time:control group' s congruent condition(766.57±75.64) ms,incongruent condition(879.52±62.31) ms,MMP group' s congruent condition (821.89±64.44) ms,incongruent condition (906.29 ± 69.46) ms,P＜ 0.001 ; error rate: control group' s congruent condition (4.15± 2.92) ％,incongruent condition (8.70 ± 6.12) ％,P＜ 0.001,MMP group' s congruent condition (12.07 ±10.80) ％,incongruent condition (16.60±12.43)％,P＜0.01).(2)ERPs data showed that MMP demonstrated significantly smaller incongruent-N2/N450/SP amplitudes than controls,and all disappearing incongruent effects in N2,N450 and SP,comparing statistically significant incongruent effects for controls in N2,N450 and SP.In MMP group,the amplitudes of N2 and N450 incongruent condition (N2 (1.40± 2.91) μV、N450 (1.29 ± 0.55) μV) were bigger than congruent condition amplitudes(N2(0.77±3.61) μV 、N450(0.83± 1.07) μV,P＜0.05),but the amplitude of SP (0.37±3.58)μV was smaller than congruent condition(1.53±3.05) μV,P＜0.001 ;in control group,the amplitudes of N2 and N450 incongruent condition((-0.30±3.45) μV,N450(1.77± 1.55)tμV) were smaller than congruent condition (N2(1.10±3.64) μV,P＜0.001； N450(2.37±2.12) μV,P＜0.05),the amplitude of SP ((1.93±1.65) μV) was bigger than congruent condition((0.98±2.02)μV,P＜0.01).Conclusion There are impaired executive control functions during the conflict monitoring process and the conflict resolution process for MMP.These results provide the neural electrophysiological evidence to explain relapse behaviors in methadone maintenance patients.

Objective To study the risk factors for children with acute central nervous system(CNS)viral in-fection,so that pediatrician may identify children with poor prognosis at early stages of the disease,and provide them with a theoretical basis for clinical treatment. Methods The clinical data of a cohort patients of acute CNS viral infec-tion who were hospitalized at the First Affiliated Hospital of Fujian Medical University between January 2010 and June 2013 were retrospectively collected and analyzed. According to Glasgow outcome scale on discharge,children were di-vided into good prognosis group and poor prognosis group. Clinical data and outcomes were analyzed by using univariate analysis and binary Logistic regression multivariate analysis. Results Three hundred and one cases were enrolled,278 (92. 36% )patients were assigned to the good prognosis group,and 23(7. 64% )patients were assigned to the poor prognosis group. By univariate analysis,the patients in the poor prognosis group had longer duration of sickness before admission,longer time of fever,lower white blood cell count in cerebrospinal fluid,a relatively lower calcium level,con-scious disturbance at the early stage,multiple seizures,convulsive status epilepticus,meningeal irritation sign,muscle weakness,severe changes in electroencephalogram(EEG),and abnormal neuroimaging findings(computed tomography or magnetic resonance imaging,or both)had significant differences between the good prognosis group and the poor short - term outcome groups(all P < 0. 05). By binary Logistic regression multivariate analysis,factors indicating a poor prognosis during the early stage were conscious disturbance at the early stage(0R = 4. 885,95% CI:1. 523 - 15. 670, P = 0. 008),multiple seizures(0R = 6. 352,95% CI:1. 905 - 21. 178,P = 0. 003),severe changes in EEG( 0R =4. 269,95% CI:1. 708 - 10. 666,P = 0. 002),and abnormal neuroimaging findings( 0R = 9. 740,95% CI:2. 360 -40. 192,P = 0. 002). Conclusions Conscious disturbance at the early stage,multiple seizures,severe changes in EEG and abnormal neuroimaging findings are risk factors for acute viral infection of CNS in children.

Objective To investigate the bioactivities of controlled release bFGF microspheres (Ms) and their effects on the cultured osteoblasts. Methods The secondary cultured osteoblasts were divided into four groups according to the different ingredients being added to the DMEM culture medium, ie, control group,bFGF group, bFGF-PLGA-Ms group and bFGF-PELA-Ms group. The proliferation of the cultured osteoblasts was measured with cell counting method, MTT method and flow cytometry. The content of bone BGP secreted by osteoblast was also measured with RIA method. Results The in vitro cellular study showed no significant difference in the cell number and cell viability of four groups one day after plate culture.The cell number and cell viability in the bFGF-PLGA -Ms group were more than those in other three groups four and six days after plate culture. The cell number and cell viabilitythose in the bFGF group were more than those in the bFGF-PELA-Ms group six and eight days after plate culture with insignificant difference. The flow cytometrical examination showed that the G 2/M+S percentage in the bFGF group reached the highest two days after plate culture and the G 2/M+S percentage in the bFGF-PLGA-Ms group went the highest four and eight days after plate culture. Among four groups, the content of BGP in the bFGF-PLGA-Ms group was the highest and the bFGF-PELA-Ms group the next. Conclusions The effect of bFGF-PELA-Ms is not satisfactory,as indicates that the manufacturing method needs improving. However,the bFGF-PLGA-Ms can promote the proliferation and differentiation of the osteoblasts through a long period of controlled release of bFGF.

AIM　To prepare lung targeted tetrandrine (TET) loaded sustained-release drug delivery system by microencapsulation, decrease the toxicity and enhance the therapeutic function of anti-pulmonary hypertension of TET. METHODS　Albumin microcapsules were produced by spray drying-thermal denaturation, a new technique. Some characterization of the prepared microcapsules was evaluated. Distribution of the microcapsules and their anti-pulmonary hypertension effect in vivo were investigated. RESULTS　The spherical microcapsules showed a drug loading of 37.88%. Compared to the original drug, the rate of TET released from the positively charged microcapsules in vitro was significantly decreased and fitted well by Higuchi equation. The TET concentrations in mouse lungs of TET microcapsules were significantly higher than those of TET injection, and the mean retained time of TET in lungs was prolonged from 157.1 h to 223.6 h after microencapsulation. The in vitro - in vivo correlation was established and confirmed (P＜0.001). CONCLUSION　The new spray drying-thermal denaturation method allows the preparation of drug loaded albumin microcapsules with desired results. The prepared microcapsules were found to have the potential function of delivering TET to pulmonary artery via iv, with low toxicity and high efficacy.
