Objective To study the protective effect of glutamine on the intestinal mucosal antioxidation in endotoxemic rats. Methods　Twenty-eight male Wistar rats were randomly divided into three groups, group A:parenteral nutrition supplemented with glutamine, group B:TPN without glutamine,and group C:normal control. Endotoxemia was induced by continous intravenous infusion of lipopolysaccharide(LPS) at a dose of 2 mg/kg per day throughout the 5-day study period. The mucosal protein、DNA、ATP、SOD、MDA、GSH、sIgA were determined. Results The mucosal protein、DNA、ATP、SOD、GSH and sIgA content in endotoxic rats were markedly decreased, MDA was increased as compared with normal control(P＜0.05). The former indices in group A were improved and MDA content was decreased as compared with group B(P＜0.05). Conclusion　Glutamine can improve gut energy metabolism, decrease the extent of mucosal injury of free radicals, and give an protective effect on the mucosal probably by increasing GSH.

Objective To discuss the clinical features and related factors of psychosis in patients with Parkinson's disease (PD) and assess the prevalence of psychosis.Methods A total of 82 patients with Parkinson's disease and 69 healthy controls were evaluated by Brief Psychiatric Rating Scale and neuropsychiatric questionnaire.For the PD group,the age at PD onset,type and dose of PD medications,and rapid eye movement (REM) sleep behavior disorder (RBD) were recorded.Unified Parkinson's disease rating scale (UPDRS,parts Ⅱ and Ⅲ) and Hoehn-Yahr staging were used for the evaluation of the severity of motor dysfunction,Hamilton depression scale (HAMD) for emotional state,montreal cognitive assessment (MoCA) for cognition,and scales for outcomes in Parkinson's disease-SLEEP (SCOPA-SLEEP) for quality of sleep.Results The prevalence of psychosis was 36.59％ in PD patients and 2.90％ in the control group.The difference between the two groups was statistically significant (P＜ 0.001).Among the 30 PD patients with PD psychosis meeting the NINDS/NIMH criteria,patients experienced illusions,false sense of presence,hallucinations and delusions was 22.0％,14.6％,29.3％,and 7.3％,respectively.Univariate analysis showed that age,levodopa equivalent dosage,SCOPA-SLEEP scores,and prevalence of RBD were significantly higher in thePDP group [(71.1±6.18),(628.7±283.2),(15.3±7.28),60.00％] than in the PDNP group [(66.6±9.25),(461.1±317.2),(9.7±7.64),28.85％] (all P＜0.05).Multivariate analysis showed that Hoehn-Yahr staging was a protective factor (OR =0.039,95％ CI:0.004-0.402),while sleep disorder was a risk factor (OR=1.157,95％CI:1.015-1.320).The PD patients with more psychotic symptoms were much older and with higher SCOPA-SLEEP scores,which had a statistically significant difference (P =0.0042,P =0.0112).Conclusions The prevalence of psychosis is much higher in PD patients than in healthy controls.PD psychosis is correlated with older age,larger levodopa equivalent doses,higher SCOPA-SLEEP scores,and prevalence of REM sleep behavior disorder.

Objective To investigate the clinical result, complication and influential factors of lyophilized and radiation-sterilized morselized allogeneic bone. Methods Between December 1995 and December 2000, 778 cases with implantation of bone allograft were performed. There were 188 females and 590 males with an average age of 37.2 years (range, 6-76 years). The lyophilized morselized allogeneic bone was processed according to American Association of Tissue Bank (AATB) standards and was sterilized by radiation. The bone allograft was rehydrated in fresh blood or in physiologic saline before implantation. The morselized allograft was used to fill defects attributable to various causes such as 84 bone tumors (10.8%), 551 fractures (70.8%), 143 joint fusions (18.4%). After implantation of the bone allograft, drainage was carried out for 2~3 days and antibiotics were used to prevent infection. The average amount of the allograft implanted was 24 g (range, 4-64 g). Results All patients were followed up clinically and radiographically. The minimum length of follow-up was 3 years with an average follow-up period of 59.7 months (range, 36-96 months), 722 allograft unions occurred at a mean of 4.5 months postoperatively (range, 3-8 months). There were 137 complications, included 44 of wound effusion (5.65%), 29 of delayed wound healing (3.72%), 2 of profuse liquid accumulation (0.26%), 43 of fracture non-union (5.52%), 4 of tumor recurrence (0.51%), 9 of fusion failure (1.15%) and 6 of fracture (0.77%). Estimated by the combined Mankin and Komender standards, 688 (88.44%) patients were satisfied with their outcomes while the other 90 (11.56%) patients were dissatisfied. Conclusion The lyophilized and radiation-sterilized morselized allograft is of good tissue compatibility and able to promote bone formation, it can be considered as a convenient, safe, and available material for bone transplantation. The important factors affecting allograft healing are the mechanical stability in the recipient region, local blood supply for the site of grafting and the surgical technology. The major complications of allograft are late infection and re-fracture.

Objective To prospectively study the effects of different fluid resuscitation on kidney function in pediatric patients with sepsis.Methods One hundred and eighteen pediatric patients with sepsis shock who needed fluid resuscitation in Intensive Care Unit,Zhengzhou Children′s Hospital from June 2012 to June 2015 were selected, and they were randomly divided into group A,B and C by random number in the table.The patients received fluid resus-citation of hydroxyethyl starch,50 g/L albumin and 9 g/L saline.After that,neutrophil gelatinase associated lipocalin (NGAL),α-1 microglobulin,urea nitrogen,creatinine,urine volume,the incidence of acute kidney injury (AKI),and the renal replacement therapy rate accepted by the patients were recorded.Then all the data were analyzed with SPSS 19.0 software.Results Serum levels of NGAL and α-1 microglobulin in group A [(103.50 ±1.23)μg/L,(3.32 ± 0.20)mg/L]were higher than those in group B [(93.54 ±1.42 )μg/L,(2.71 ±0.18 )mg/L]and group C [(79.57 ±1.54)μg/L,(2.08 ±0.14)mg/L],which were statistically different(all P <0.05 );serum levels of NGAL and α-1 microglobulin in group B were higher than those in group C,which were statistically different(all P <0.05).Serum levels of urea nitrogen and creatinine in group A[(5.23 ±0.34)mmol/L,(112.00 ±7.12)μmol/L] were higher than those in group B [(3.56 ±0.31)mmol/L,(77.25 ±5.34)μmol/L]and group C[(2.95 ±0.42) mmol /L,(72.12 ±6.34)μmol/L],which were statistically different (all P <0.05);serum levels of urea nitrogen and creatinine in group B were higher than those in group C,which were not statistically different(P >0.05).The urine volume in group A [(0.50 ±0.12)mL/(kg·h)]was less than that in group B[(0.90 ±0.23)mL/(kg·h)]and group C[(1.30 ±0.14)mL/(kg·h)],which was statistically different(all P <0.05);the urine volume in group B was less than that in group C,which was not statistically different(P >0.05).In three groups,there were 13 cases (34.2%)with AKI in group A,9 cases(23.1%)with AKI in group B,and 8 cases(19.5%)with AKI in group C, the incidence of AKI in group C was less than that in group B and group C,which was statistically different(χ2 =12.74,10.43;all P <0.05).All the groups all had children accepted renal replacement therapy,there were 8 cases (21.1%)in group A,7 cases(17.9%)in group B,and 6 cases (14.6%)in group C,and the cases who accepted renal replacement therapy rate in group C were less than those in group A and group B,which was statistically different(χ2 =11.36,8.73;all P <0.05).Conclusions The adverse effect of 9 g/L saline on kidney function is less than hydrox-yethyl starch and 50 g/L albumin,and hydroxyethyl starch has more adverse effects on kidney.Thus,9 g/L saline is a better option for fluid resuscitation in pediatric sepsis patients.
