Methods The rats were prepared by exposure of the superior sagittal sinus.The dura mater near the SSS was stimulated and NF-?B protein was detected in coronal brain sections using standard avidinbiotin immunohistochemistry.Results The number of NF-KB positive neurons in PAG expression increased to 111.7?15.7 in stimulation group,compared with 112.9?10.7 and 508.7?30.8 in blank group and sham-operated group respectively(t=-41.52 and t=-36.21,P

Objective: To understand the relationship between coxsackievirus B and pediatric diseases. Methods: The infectious state of coxsackievirus B in hospitalized children were studied. Among 796 children studied, there were 218 upper respiratory tract infection cases, 179 pneumonia, 106 asthma, 155 myocarditis, 19 allergic purpura and 89 other diseases. The antigen (CVB-Ag) and IgM (CVB-IgM) were detected using ELISA method. Results: (1)There were 47% positive of CVB in upper respiratory tract infection and 48% positive of CVB in pneumonia(no difference between them, P>0.05). (2) There were 62% positive of CVB in asthma, 61% positive of CVB in myocarditis and 68% positive of CVB in allergic purpura(no difference among them, P>0.05)； But the positive rate of CVB in asthma, myocarditis and purpura were higher than in upper respiratory tract infection and pneumonia, (P<0.05). (3) There were lower positive rate of CVB in other kinds of diseases (16%) and in healthy children (3%)(no difference between them, P>0.05). Conclusion: CVB infection was related to several kinds of diseases, the relationship between CVB infection and diseases such as asthma, myocarditis, and allergic purpura should be further studied.

Objective To evaluate the effect of centralized procurement of artificial joint consumables on total arthro-plasty placement surgery.Methods Through a retrospective study,t-test was conducted on the medical quality and effi-ciency,hospitalization cost per time structure through July-December,2021 to July-December,2022 centralized pro-curement of joint replacement surgery in a tertiary hospital in Shanghai.Results After centralized procurement,the amount of knee arthroplasty surgery decreased,and the time of hip replacement surgery was increased,and the difference was statistically significant(P＜0.05).The total cost,cost of consumables,arthrotomy fee of the two types of arthroplasty surgery were significantly decreased,and the difference was statistically significant(P＜0.05).In addition,the average cost of other consumables hospitalization of knee joint surgery patient increased,and the difference was statistically significant(P＜0.05).Conclusion After centralized procurement of artificial joint consumables,the cost of total knee arthroplasty and total hip arthroplasty has decreased significantly,and the quality and efficiency of medical care have not changed significantly.At the same time,hospital managers should pay more attention to the rational use of consumables after centralized procurement.In addition,it calls for increasing the price of surgery to reflect the value of physician services.

OBJECTIVE: To investigate the three-dimensional lip vermilion changes after extraction and non-extraction orthodontic treatment in female adult patients and explore the correlation between lip vermilion changes and incisor changes. METHODS: Forty-seven young female adult patients were enrolled in this study (skeletal Class III patients were excluded), including 34 lip-protruding patients treated by extraction of four first premolars (18 patients requiring mini-implants for maximum anchorage control and 16 patients without mini-implants) and 13 patients requiring non-extraction treatment. Nine angles, seven distances, and the surface area of the lip vermilion were measured by using pre- and post-treatment three-dimensional facial scans. Linear and angular measurements of incisors were performed on lateral cephalograms. RESULTS: There were no significant changes in the vermilion measurements in the non-extraction group. The vermilion angle, vermilion height, central bow angle, height/width ratio, and vermilion surface area decreased significantly after the orthodontic treatment in the extraction groups, but the upper/lower vermilion proportion remained unchanged. Significant correlations were found between the changes in incisor position and those in vermilion angles, vermilion height, and surface area. CONCLUSIONS Extraction of the four first premolars probably produced an aesthetic improvement in lip vermilion morphology. However, the upper/lower vermilion proportion remained unchanged. The variations in the vermilion were closely related to incisor changes, especially the upper incisor inclination changes.

OBJECTIVETo evaluate the association between single nucleotide polymorphisms (SNPs) of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) gene and susceptibility to cervical cancer.

METHODSOne hundred patients and 100 healthy controls from Hubei province were genotyped for 20 polymorphic loci using Sequenom.

RESULTSThe frequency of rs11571316 G allele and rs5742909 T allele, which are localized in the promoter region, and rs11571319 A allele, which is downstream of the gene, were significantly higher in patients than in controls. Luciferase assay showed that, as the previously reported rs5742909 T allele, rs11571316 G allele could significantly increase the expression of the reporter gene.

CONCLUSIONSNPs in the promoter region of (CTLA4) gene might increase the susceptibility to cervical cancer by increasing (CTLA4) gene expression.

OBJECTIVETo analyze the comorbidities in patients with cerebral palsy (CP) from two perspectives as neurologic subtype and gross motor functions, and find their correlations.

METHODSChildren with cerebral palsy treated in the rehabilitation center from January 2007 to June 2009 received the following examinations: intelligence capacity test, ophthalmologic consultation, language-speech test, brainstem auditory evoked potential and electroencephalogram. They were stratified according to both neurologic subtype and gross motor functions to detect the occurrence of comorbidities.

RESULTSOf all the 354 cases, 166 (46.89%) had mental retardation, 15 (4.24%) auditory limitations, 138 (38.98%) visual disorder, 216 (61.02%) language-speech disorder and 82 (23.16%) epilepsy. The frequency of individual comorbidities were distributed disproportionately between the different neurologic subtypes. Correlation analysis showed that there was a significant correlation between the spastic diplegia and the visual disorder (correlation coefficient = 0.26), between spastic hemiplegia and epilepsy (correlation coefficient = 0.17), between spastic quadriplegia and epilepsy and mental retardation (the correlation coefficient was 0.38 and 0.11, respectively) and between both dyskinetic and mixed children and language-speech disorder (the correlation coefficient was 0.24 and 0.27, respectively). The frequency of individual comorbidities was distributed disproportionately between the different neurologic subtypes and between the different GMFCS levels (P < 0.05), except for the frequency of visual disorders (chi(2) = 1.90, P > 0.05); and with the increase of the GMFCS levels, the burden of the comorbidities were more heavy and the incidence of the comorbidities was higher. Multi-comorbidities were relatively infrequently encountered in those with spastic hemiplegic or spastic diplegic children or patients whose GMFCS levels were I-III, while these entities occurred at a frequent level for those with spastic quadriplegic, dyskinetic, or mixed or children whose GMFCS levels were IV and V, and the differences were significant (P < 0.05). The mean GMFCS levels of children with spastic quadriplegic, dyskinetic or mixed CP were higher than level III, most of them had no ability of ambulation;while the mean GMFCS levels of spastic hemiplegic or spastic diplegic children were below level III, most of them could walk independently.

CONCLUSIONSThere are correlations between the occurrence of the comorbidities such as mental retardation, auditory or visual impairments, language-speech disorders, epilepsy and the cerebral palsy subtype and the gross motor function levels. Clinicians should have a full recognition of these comorbidities, and we should have a cooperation between the different subjects to have an overall evaluation and rehabilitation and to improve the prognosis.

OBJECTIVETo investigate the correlation between impaired non-viral specific immune function of dendritic cell (DC) and viral clearance and cytotoxic T lymphocyte (CTL) response to HBV or HCV in patients with HBV and HCV coinfection.

METHODSTwenty-five patients with HBV and HCV coinfection were investigated in this study. In 1994 and 2002, biochemical and virological markers and quantitative serum HBV DNA and HCV RNA levels were detected in these patients. According to the virus clearance status, these patients were divided into 4 groups: 14 patients with both HBV and HCV clearance (Group A), 6 patients with HCV clearance only (Group B), 3 patients with HBV clearance only (Group C), and 2 patients with persistent infection of HBV and HCV (Group D). Phenotypes and immune functions of monocyte-derived DCs were compared between these groups. 51Cr release assay were used to measure CTL response to epitopes derived from HBV, HCV or influenza virus (as positive control) in HLA-A2+ patients.

RESULTSImpaired non-viral specific immune functions of DCs were observed in group B, C and D compared with group A and normal donors (Group N). These impaired functions included CD86 decreasing expression and lower capacity to stimulating allogenic T cells and uptaking antigen. The specific CTL response to HBV- and HCV-derived peptides could be induced in group A (12/12). The specific CTL response to HBV-derived peptides or to HCV-derived peptides could be induced in group C (3/3) or B (5/5), respectively. But the specific CTL response to both of two HBV-derived peptides or two HCV-derived peptides could not be induced in group C (0/3) or B (0/5), respectively. And no CTL response to HBV or HCV-derived peptides could be induced in groups D (0/1) and N (0/4).

CONCLUSION1. The results suggest that specific CTL response to HBV or HCV play a vital role in the viral clearance. 2. The DCs with impaired non-viral specific immune functions exist in chronic patients with HBV and/or HCV infection, but do not interfere with clearance and CTL response to HBV or HCV. It is reasonable to speculate that impaired functions of DCs result from viral infection.

OBJECTIVETo evaluate the health-related quality of life and postdischarge long-term outcome after severe acute pancreatitis.

METHODSThe hospital records of patients with SAP discharged healthy from January 2003 to December 2003 were reviewed. The Rand 36-item Health Survey with accessory question was mailed to each patient. The means and deviations for each of eight scales scores of SF-36 were calculated, the study population scores were compared with general Chinese population; Univariate analysis was applied to determining the effects of variables such as age, sex, causes of disease, mode of treatment, frequency of surgery, financial burden, length of stay, chronic complications. Accessory questions were analyzed separately.

RESULTSThe means and deviations for each of eight scales (PF, RP, RE, BP, VT, MH, SF, GH) scores of SF-36 in SAP patients were 83 +/- 15, 62 +/- 42, 69 +/- 36, 80 +/- 15, 69 +/- 19, 72 +/- 15, 75 +/- 18, 65 +/- 18, compared with general people. Except RP and SF, the others were similar. In the ANOVA of Physical Component Summary, the three variables mode of treatment, financial burden and length of stay were included (P < 0.05), while in that of Mental Component Summary, the two variables of gender and financial burden were included (P < 0.05).

CONCLUSIONSThe health-related quality of life in SAP patients is similar to that of general people. Greater attention should be given to mode of treatment, length of stay and financial burden to improve quality of life.
