Objective To determine the appropriate dosage of parexoxib sodium for postoperative analgesia in different age children with day surgery.Methods One hundred and eighty ASA Ⅰ children aged 1-12 yr scheduled for day surgery undergoing sevoflurane anesthesia combined with lateral inguinal regional blockade were divided into 3 groups according to age ( n =60 each):group 1-3 yr (group Ⅰ ),group 4-6 yr (group Ⅱ ) and group 7-12 yr (group Ⅲ).Eeach group was randomly divided into 2 sub-groups( n =30): parecoxib sodium 0.5 mg/kg (sub-group A) and parecoxib sodium 1.0 mg/kg (sub-group B).Sub-groups A and B received iv injection of paracoxib sodium 0.5 or 1.0 mg/kg respectively immediately at skin incision.Analgesic effect was evaluated by FLACC score (group Ⅰ ),CHEOPS score (group Ⅱ ) and VAS scroe (group Ⅲ) at 6(T1 ),12(T2 )and 24 h (T3)after operation.The effective analgesia was defined as FLACC score≤3,CHEOPS score≤7 or VAS score≤ 3.Side effects were also observed.Results Compared with sub-group B,FLACC score was significantly increased at T1 in sub-group Ⅰ -A ( P ＜ 0.01 ).There was no significant difference in CHEOPS score or VAS score between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B (P ＞ 0.05).The incidence of effective analgesia was 97％ in group Ⅰ (93％ in group sub-group Ⅰ -A,100％ in sub-group Ⅰ -B),100％ in group Ⅱ and 93％ in group Ⅲ (97％ in sub-group Ⅲ-A,90％ in sub-group Ⅲ-B).There was no significant difference in the incidence of side effect between sub-groups Ⅰ -A and Ⅰ -B,between sub-groups Ⅱ -A and Ⅱ -B,and between sub-groups Ⅲ-A and Ⅲ-B ( P ＞ 0.05).Conclusion Parecoxib sodium 1.0 or 0.5 mg/kg can be used in postoperative analgesia in children aged 1-3 yr or 4-12 yr with day surgery respectively.

Methods: A total of 10 specific pathogen free (SPF) grade female DBA/2J mice were randomly divided into model group and QGA II group (n = 5 for each group), while additional 5 SPF-grade female C57BL/6J mice were assigned to control group. Mice presented spontaneous high IOP and showed elevated approximately at the age of seven months. The high IOP was maintained until week 38, when gavage was initiated. Mice in control group underwent the same intragastric treatment, while those in QGA II group were gavaged with QGA II (9.67 g/kg), once a day for four weeks. Retinal morphology was examined using hematoxylin and eosin (HE) staining, with the number of retinal ganglion cells (RGCs) counted. The expression level of Brn3a protein, a specific marker for RGCs, was detected by immunofluorescence, with the mean optical density (OD) measured for quantitative analysis. In addition, 16S rDNA sequencing was leveraged to analyze changes in the diversity of gut microbiota, including their α-diversity (Chao1, Shannon, Pielou’s evenness, and observed species index) and β-diversity. Venn diagrams and linear discriminant analysis effect size (LEfSe) analysis was employed to investigate the number of amplicon sequence variants (ASVs), the abundance of differential gut microbiota species, and the classification of species at both the phylum and genus levels within the three groups of mice. Results: HE staining revealed that compared with control group, model group showed significant reduction in the number of RGCs (P < 0.01), with intracellular vacuolar degeneration and nuclear pyknosis. After QGA II treatment, the number of RGCs was significantly increased compared with model group (P < 0.01), with notable improvements in intracellular vacuolar degeneration. Immunofluorescence analysis showed that the mean OD of Brn3a protein was significantly decreased in model group compared with control group (P < 0.01), while QGA II treatment significantly elevated its expression level (P < 0.01). Analysis of α-diversity showed that after QGA II intervention, the Chao1, Shannon, and Pielou’s evenness indices were significantly increased (P < 0.01), and the observed species index was elevated (P < 0.05). β-Diversity analysis demonstrated distinct clustering among the three groups, indicating relatively low similarity in bacterial community structures. ASV clustering identified a total of 14 061 ASVs across all groups, with 9 514 ASVs shared between model and QGA II groups. At the phylum level, the abundance of Bacteroidetes was significantly decreased in model group compared with control group (P < 0.01), while Firmicutes and the Firmicutes/Bacteroidetes (F/B) ratio were significantly increased (P < 0.01). QGA II treatment significantly reduced both Firmicutes abundance and the F/B ratio (P < 0.01). At the genus level, Lactobacillus was dominant across all groups, with its abundance significantly increased in model group (P < 0.01) and subsequently decreased following QGA II intervention (P < 0.05). Conclusion QGA II restructured the gut microbiota of DBA/2J mice with chronic high IOP, bringing changes in their diversity and abundance of components. Firmicutes, Bacteroidetes, Lactobacillus, along with their associated microorganisms, are likely critical components of the gut microbiota that contribute to the optic neuroprotective effects of QGA II on chronic high IOP mice.

ObjectiveTo investigate the family adaptability, cohesion and their relationship with symptoms of chronic outpatients with schizophrenia.Methods51 outpatients with schizophrenia were assessed with Family Adaptability and Cohesion Scales, Second Edition, Chinese Version(FACE II-CV) and Positive and Negative Syndrome Scale(PANSS ).ResultsThe level of family adaptability of chronic outpatients with schizophrenia was lower than that of the normal control(u<0.05 or u<0.01);the ratio of the balance category of family decreased significantly and that of the extreme category of family increased significantly;the score of real cohesion negatively correlated with scores of PANSS, Positive Subscale and General Psychopathology Subscale (P<0.05);the score of real adaptability negatively correlated with score of Positive Subscale (P<0.05). ConclusionsFamily adaptability and cohesion of outpatients with schizophrenia close correlate to symptoms of chronic outpatients with schizophrenia and level of family adaptability decreases.

ObjectiveTo study the relationship between mental symptoms and the social functioning of outpatients with schizophrenia.Methods93 outpatients with schizophrenia received tests of Positive and Negative Syndrome Scale(PANSS) and Morningside Rehabilitation Status Scale(MRSS).ResultsThe total score of MRSS,the score of Dependency Scale(DEP),Inactivity Scale(INACT) and Social Isolation Scale(ISOL) had positive correlation with scores of PANSS,Positive Subscale,Negative Subscale and General Psychopathology Subscale(P<0.01).ConclusionsThe social functioning of outpatients with schizophrenia has close correlation to their mental symptom,the more plentiful the mental symptom is,the more serious the social functioning damage is.

OBJECTIVETo investigate the clinical effect of modified Koyanagi technique with coverage by tunica vaginalis of testis in severe hypospadias.

METHODS49 cases with severe hypospadias treated from Jan. 2009 to Sep. 2011 were retrospectively studied. 25 patients underwent Koyanagi technique with coverage by tunica vaginalis of testis. 24 cases underwent one-stage Duplay + Duckett technique in the same term. The patients were followed up for 7-24 months.

RESULTSAmong the 25 children treated with Koyanagi procedure, 20 cases were cured, 5 patients had postoperative complications, including urethral fistula in 3 cases,urethral stenosis in 2 cases. At the same time, in the Duplay + Duckett group, 17 cases were cured, 7 children had postoperative complications, including urethral fistula in 4 cases, and urethral stenosis in 3 cases. All the patients with urethral fistula were repaired successfully 6 months after the first surgery; The urethral stenosis were cured by dilatation within 1 to 3 months. The successful rate in the 2 groups had no significant difference(P >0.05).

CONCLUSIONSKoyanagi technique with coverage by tunica vaginalis of testis is relatively simple with similar effect as Duplay + Duckett technique for severe hypospadias.
