Objective To analyze the effects of Ileus tube (IT) along with somatostatin (SS) used for treatment of patients with severe acute pancreatitis (SAP).Methods Under conventional treatment,75 patients with SAP were divided into three groups as per different additional treatments,namely group A (IT and SS),group B (nasogastric decompression tube and SS),and group C (IT alone),and the therapeutic efficacies of those treatments were evaluated in respects of improvement of physical signs and symptems,dynamic changes in decompression drainage and prognosis.Results Therapeutic efficacy was 100％ in group A,84％ in group B and 80％ in group C.The difference between group A and B was x2 =8.26 (P ＜0.01) ; group B vs.C was x2 =0.38 (P ＞ 0.05).The physical signs and symptoms in group A were improved more rapid than those in group B and C (P ＜ 0.05),but there was no significant differences in those signs and symptoms between group B and group C (P ＞ 0.05).In comparison of decompression drainage,the t value of group A vs.group B was 2.14,group B vs.group C was 3.83,and group A vs.group C was 2.23 (P ＜ 0.05).As cure rate of patients with SAP in hospital on the 14th day,rate of transferring to surgical treatment as a last resort and mortality in group A were compared with group B and C,the differences were statistically significant (P ＜ 0.05),while group B vs.C,the difference was not statistically significant (P ＞ 0.05).Conclusions Application of IT combined with SS can significantly improve the condition of patients with SAP,thereby reducing the operation rate,shortening hospital stay,lowering mortality and improving the outcome,and it is worthy of clinical popularization.

Objective To analysis the long-term retention rate of Levetiraceram (LEV) monotherapy or combination therapy of infant epilepsy. Methods The clinical data of patients with infant epilepsy treated by LEV had been retrospectively analyzed from July 2006 to June 2007. Results Sixty patients with infant epilepsy treated by LEV had been recruited, 20 cases with partial seizures, 19 cases with generalized seizures, 21 cases with epilepsy syndrome. Among them 21 cases was intractable epilepsy. The retention rates of LEV in 6-month, 1-year, 2-year, 3-year and 4-year were 95.5%, 75.0%, 60.0%, 51.7%, and 38.3%. The most common reason for withdrawal was lack of effect (43.2%). COX regression model suggested that duration>1 month (RR=2.91, 95%CI:1.16~7.30) and refractory epilepsy (RR=2.30, 95%CI:1.22~4.32) were risk factors of withdrawal (all P<0.05). After treatment, the seizure frequency signiifcantly reduced compared with baseline (P<0.01). To the end of the follow-up, the efifciency was 100%and the complete remission rate was 69.57%in 23 cases continued treatment. The main side effect were fatigue (56.0%), and sleep increased, irritability, and so on. Conclusions LEV monotherapy or combination therapy has well long-term retention rate, maintains well efifcacy and tolerability in infant epilepsy.

Aim To explore the effect and mechanism of resveratrol (Res) on proliferation and differentiation of murine 3T3-L1 preadipocytes.Methods 3T3-L1 preadipocytes were cultured and treated with resveratrol in different dosages.Cell proliferation was analyzed by WST-1 method. Oil red O staining method and spectrophotography were applied to analyze the degree of differentiation. Real-time PCR was applied to detect the mRNA expression of adiponectin and leptin. Western blot was applied to detect the expression of silent information regulator 1 (Sirt1),peroxisome proliferator activated receptor γ (PPARγ) and CCTTA enhancer binding proteinα (C/EBPα).Results Res inhibited proliferation of murine 3T3-L1 preadipocytes in a time-dose dependent manner.The expression levels of adiponectin and leptin mRNA were decreased, and Res also inhibited 3T3-L1 preadipocytes to differentiate into mature adipocytes. Res increased the expression levels of Sirt1 and decreased the expression levels of PPARγ and C/EBPα.Conclusions Resveratrol can inhibit the proliferation and differentiation of 3T3-L1 preadipocytes.The underlying mechanisms may include enhancing expression of Sirt1 and inhibiting expression of PPARγ,C/EBPα which are related to cell differentiation.

Objective To explore the imaging characteristics of neurologic complications associated with the enterovirus 71 ( EV71 ) epidemic by analyzing 25 cases and reviewing the literature. Methods Twenty-five cases of hand-foot-mouth disease with neurologic complications during the recent EV71 outbreaks of Hainan province were studied for the clinical features and imaging findings, and literature were reviewed.Results In 5 cases, acute flaccid paralysis associated with EV71-infected hand-foot-mouth disease was related to the linear high signal in the spinal cord on sagittal images. Two cases showed symmetrical, welldefined hyperintense lesions in the spinal cord on T2WI transverse. Strong enhancement of the ventral horns and root was seen on the contrast-enhanced axial T1WI. In brainstem encephalitis, all lesions presented with significant hyperintensity on T2WI and hypointense on T1WI in the posterior portions of the medulla oblongata, midbrain, and pons. The manifestations of aseptic meningitis (AM) on MRI have no characteristics, but subdural effusion, meningeal enhancement and hydrocephalus can be the indirect signs of AM. Conclusions MRI is an effective method to investigate neurologic complications associated with the EV71 epidemic. Posterior portions of the medulla oblongata and pons, bilateral ventral horns of spinal involvement are characteristic findings of enteroviral encephalomyelitis.

Objective To explore psychological resilience, anxiety, depression, coping styles and social supports status among parents of preterm infants of ophthalmic clinic, and analyze their relationship. Methods A total of 217 parents of preterm infants at ophthalmic clinic of hospital were selected by convenience sampling method and investigated by self- designed general information questionnaire, Connor-Davidson Resilience Scale, Self-rating Anxiety Scale, Self-rating Depression Scale, Social Support Rating Scale, and Simplified Coping Style Questionnaire. Results The total score of psychological resilience was (67.48 ± 14.20) points. The average score of positive coping styles dimension was (1.98±0.50) points, and negative coping style dimension score was (1.19±0.55) points. The social support score was moderate with a total score of (42.75 ± 6.17) points, the anxiety and depression got a total score of (36.77 ± 8.17) points and (39.67 ± 9.02) points respectively. Psychological resilience was negatively correlated with anxiety and depression (r=-0.363--0.242, P<0.01), and was positively correlated with coping styles and the social support (r=0.141-0.312, P<0.05 or 0.01). Multi-factor linear regression analysis showed that depression and social support were the influence factors of psychological resilience(t=-4.376, 2.516, P<0.01 or 0.05). Conclusions The parents of preterm infants are at the poor psychological states. Coping styles and depression are the important factors which affect psychological resilience among parents of preterm infants. Nurses should assess the psychological status of the parents, provide targeted interventions to relieve stress, guide the parents use social support effectively, and improve their psychological state.

AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ.
METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared.
RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05).
CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.

Objective To construct a novel tissue?engineered bone matrix gelatin (BMG)/poly[butylene succinate?co?tere?phthalate] (PBST) biphasic scaffold for annulus fibrosus. Methods The PBST spinning fibers were prepared by electrospinning and the porosity and water absorption rate were tested. Rabbit annulus fibrosus cells were isolated, cultured and identified through SafraninOstaining, and collagenⅡimmunohistochemical staining in vitro. And then annulus fibrosus cells were implanted on the PBST fiber, whose growth situation was observed by scanning electron microscope (SEM). Then the BMG/PBST biphasic scaf?fold was constructed by BMG as the outer annular fibrosus and PBST fiber as the inner annular fibrosus. The annulus fibrosus cells were implanted on the biphasic scafflod and cultured for 3, 7 and 21 days in vitro. The biomechanical and biological property was observed at the predetermined time point. Results The porosity of the fiber was 61.83%±7.33%and its water absorption rate was 297.34%± 57.13%. The identified result of annulus fibrosus cells were positive, suggesting that the cells have still kept their annulus fibrosus cells characteristics. The cells growth could be observed through SEM at 3rd and 7th day after implanted on the fi?bers. After cultured on the BMG/PBST scaffold, HE staining proved that the cells could ingress into the inner of fiber with time. SafraninOstaining and collagenⅡimmunohistochemical staining proved that the cells can secreted abundant proteoglycan and collagenⅡ, the special annulus fibrosus cell extracellular matrix. Compared with the BMG/PBST scaffold without cells, the elastic modulus of biphasic scaffold was increased from 14.83±1.02 MPa to 17.56±1.47 MPa after cultured with cells for 21 days in vitro. Conclusion The novel tissue?engineered biphasic scaffold for annulus fibrosus constructed with BMG and PBST fiber spinning has good cytocompatibility and biomechanical characteristics, which provide a basis for the complete tissue engineered interverte?bral disc.
