[Objective]To study the change of amplitude-integrated electroencephalography(aEEG)and the relationship with neurological prognosis in children with brain injury.[Methods]This study included 100 brain injured children,100 normal children as the control group. Quantitative aEEG in frontal,temporal,parietal and central lobe were compared. The aEEG in brain injured chil?dren were reexamined after 1 week. The follow-up was observed after 3 months and pediatric cerebral performance category score (PCPC)was recorded for each patient.[Results]The 2-12 months group frontal and temporal lower margin amplitude were signifi?cantly increased,P<0.05,bandwidth in frontal,temporal and central channels were significantly decreased,P<0.05. In 13-35 months group all lower and upper margin amplitudes were significantly higher in brain injury group than normal control group ,P<0.05. In 36-71 months group,frontal,temporal,parietal and central lower margin amplitude were significantly increased,P<0.05. However,only upper margin amplitude in frontal and parietal lobe were significantly different,P<0.05. In 72-155 months group,the lower margin amplitude of frontal,central,parietal and temporal channels were significantly increased,P<0.05;the upper margin amplitude of frontal,central,parietal channels were significantly different,P<0.05;the bandwidth were significantly different in fron? tal and parietal channels,P<0.05. In 156-216 months group,the lower and upper margin amplitude of frontal,central,parietal and temporal channels were significantly increased ,P<0.05;the bandwidth were significantly different in frontal channel ,P<0.05.Correla?tion analysis shows that the PCPC after 3 months was significantly correlated to upper and lower voltage of parietal channels,r=0.222, 0.219,respectively.[Conclusion]The lower margin amplitude in brain injured children were changed,and the early aEEG of pari?etal channel have predict value for early prognosis.

OBJECTIVETo search for the genes which could interact with newly found homo sapiens cross-immune reaction antigen (PCIA1) gene and accordingly to provide insights into the study of the gene function.

METHODSThe Stratagene's BacterioMatch Two-Hybrid System and BacterioMatch Fetal Kidney Library were adopted and the recombinant bait plasmid pBT-PCIA1 was cotransformated with the target plasmid pTRG-cDNA library DNA into the reporter stain. After screening and isolation of positive pTRG clones, the target genes were identified by DNA sequencing and bioinformation analysis.

RESULTSAmong all the seven detected target genes, three genes' function were not known, the other four genes had important functions. Their mutations or abberant expression resulted in severe diseases and overexpression of ACTN4 (actinin, alpha 4), PSAP (prosaposin) or EIF3S10 (eukaryotic translation initiation factor 3, subunit 10 theta) could promote tumor development and progression.

CONCLUSIONThe bacterial two-hybrid system technique is an efficient method, which can provides insights into the study of novel genes' function by detecting protein-protein interactions. This study indicates that PCIA1 gene expression correlates with tumor formation, invasion and metastasis.

OBJECTIVE To compare the efficacy and safety of Cefazolin sodium for injection， Cefuroxime sodium for injection， and Ceftazidime for injection from nationally organized centralized drug procurement （hereinafter referred to as “centralized procurement”） and non-centralized procurement in patients with bacterial infection. METHODS The case data of hospitalized patients who had used 3 kinds of Cephalosporins for injection from centralized procurement or non-centralized procurement in the treatment of bacterial infections were retrospectively collected from 19 medical institutions in Kunming from January 2020 to September 2022. After balancing the baseline differences between the groups with the propensity score matching method， the effectiveness and safety differences of 3 kinds of Cephalosporins for injection from centralized procurement or non- centralized procurement were compared respectively. RESULTS After balancing the baseline differences among the groups， 394 cases in each group of Cefazolin sodium for injection from centralized procurement or non-centralized procurement， 472 cases in each group of Cefuroxime sodium for injection from centralized procurement or non-centralized procurement， 504 cases in group of Ceftazidime for injection from centralized procurement and 590 cases in group of non-centralized procurement were included in the analysis. In terms of effectiveness， there were no significant differences in clinical response rate， 72 h response rate， bacterial clearance rate， and the recovery rate of body temperature， white blood cell count， neutrophil count， neutrophil percentage， C-reactive protein， procalcitonin recovery between the centralized procurement group and non-centralized procurement group of Cefazolin sodium for injection and Cefuroxime sodium for injection （P＞0.05）. The proportion of patients in centralized procurement group of Ceftazidime for injection with C-reactive protein restored to normal reference range was significantly higher than that in non-centralized procurement group （46.9% vs. 27.9%， P＜0.05）， but there were no statistically significant differences in other effectiveness indicators among groups （P＞0.05）. In terms of safety， there was no statistical difference in the incidence of adverse drug reactions between centralized procurement group and non-centralized procurement group of 3 kinds of Cephalosporins for injection （P＞0.05）； the incidence of platelet count reduction in centralized procurement group of Cefazolin sodium for injection was significantly higher than non-centralized procurement group （20.7% vs. 7.1%， P＜0.05）， the incidence of eosinophilia elevation in centralized procurement group of Ceftazidime for injection was significantly higher than non-centralized procurement group （5.3% vs. 1.9%， P＜0.05）. In addition， there was no statistically significant difference in the abnormal rates of other laboratory indicators among the three types of injection Cephalosporins （P＞ 0.05）. CONCLUSIONS The efficacy of 3 kinds of Cephalosporin for injection from centralized procurement is not inferior to non- centralized procurement varieties， and the safety is equivalent to that of non-centralized procurement varieties.

To optimize the technology of Gardeniae Fructus processed with ginger juice,establish fingerprints and simultaneously determine seven compounds( geniposidic acid,chlorogenic acid,genipin-1-β-D-gentiobioside,geniposide,rutin,crocin Ⅰ,and crocin Ⅱ) by using ultra high performance liquid chromatography( UPLC). Waters ACQUITY UPLC BEH C18( 2. 1 mm×50 mm,1. 7μm) column was used with acetonitrile and 0. 1% formic acid solution as mobile phase for gradient elution at the flow rate of 0. 4 m L·min-1. The data was comprehensively processed and analyzed with similarity evaluation,principal component analysis( PCA) and partial least squares discriminant analysis( PLS-DA) methods. Twenty common peaks were identified in this study,and the similarity of samples was over 0. 97. The results of PCA and PLS-DA showed that there were differences in chemical compositions and contents between the raw Gardeniae Fructus and those processed with ginger juice,with 9 potential differentiated chromatographic peaks. After being processed with ginger juice,the contents of chlorogenic acid,crocin Ⅰ and crocin Ⅱ were less than before and the contents of other four compositions were higher than before. The optimized preparation for Gardeniae Fructus processed with ginger juice was stable and feasible. The methods of UPLC fingerprints and simultaneous determination of seven components can be effectively carried out to distinguish Gardeniae Fructus and Gardeniae Fructus processed with ginger juice.

OBJECTIVE: To study effects of postoperative regular training of core muscle strength guided by the concept of enhanced recovery after surgery (ERAS) on the rehabilitation of elderly patients with osteoporotic lumbar vertebral compression fracture after vertebroplasty (PVP) and kyphoplasty(PKP). METHODS: Ninety-four elderly patients with osteoporotic lumbar compression fractures who underwent PKP or PVP from January 2016 to January 2018 and met inclusion criteria were divided into observation group and control group. All the patients were treated with routine anti osteoporosis therapy after operation. There were 47 patients in the observationgroup, including 18 males and 29 females, with an average age of (62.62±3.21) years old;in the control group, there were 47 cases, including 17 males and 30 females, with an average age of (62.38±2.84) years old. The patients in the control group were trained by traditional way, and the patients in observation group were instructed to conduct regular training of core muscle strength according to ERAS concept. The patients were followed up for 1, 3 and 6 months after operation. Patients' conditions were quantitatively evaluated according to Barthel scale, JOA low back pain score and Oswestry Disability Index, and the differences in treatment effects between two groups were statistically analyzed and compared. RESULTS: All the patients were followed up, and the Barthel scale, JOA low back pain score and Oswestry Disability Index score of the observation group were all better than those of the control group on the 1st and the 3rd months after surgery( CONCLUSION Early regular core strength training has a positive effect on early functional recovery and improvement of life ability after PKP or PVP for elderly patients with osteoporotic lumbar compression fractures, which is in line with the concept of accelerated rehabilitation surgery.

OBJECTIVE: By comparing the clinical efficacy of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease to explore a more suitable fixed segment for the disease. METHODS: The clinical data of 46 patients with single-segment thoracic and lumbar spine III stage Kümmell disease treated from July 2013 to December 2016 were retrospectively analyzed. Forty-six patients were divided into short-segment fixation group(one vertebra above and below the diseased vertebra) and long-segment fixation group(two vertebrae on the upper and lower of the diseased vertebra) according to different methods of cement stick fixation. There were 25 patients in the short-segment fixation group, including 9 males and 16 females, with an average age of (75.3±4.5) years old, lumbar spine bone mineral density T-value of (-3.1±0.3) g/cm³, follow-up time of (13.0±2.3) months; there were 21 patients in long-segment fixation group, 6 males and 15 females, with an average age of (74.5±3.9) years old, lumbar spine bone mineral density T-value of (-3.2±0.3) g/cm³, follow-up time of (14.7±3.6) months.The gender, age, follow-up time, operation time, intraoperative blood loss, cement leakage, and the rate of adjacent vertebrae fractures were compared between two groups, as well as pain VAS score, ODI, and kyphosis angle before and after surgery. RESULTS: There were no significant differences in age, gender, bone density, pain VAS score, ODI, and kyphosis between two groups before surgery. The operation time and intraoperative blood loss of short-segment fixation group were less than that of long-segment fixation group. The pain VAS score, ODI and kyphosis of the two groups were significantly improved at 7 days after the operation and at the latest follow-up, there was no significant difference between two groups. There were no significant differences in bone cement leakage(9/25 vs 11/21) and adjacent vertebrae fractures(4/25 vs 3/21). CONCLUSIONS Both long-segment fixation and short-segment fixation can effectively relieve pain, correct kyphosis, improve functional index, and achieve better clinical results, but short-segment fixation has less operation time and less intraoperative blood. So single-segment thoracic and lumbar spine III stage Kümmell disease does not need to extend the fixed segment, short-segment fixation is more in line with clinical needs and worthy of further study.

OBJECTIVE: From the perspective of clinical application to analyze the effectiveness and reliability of CPC/PMMA bone cement in percutaneous kyphoplasty (PKP) for the treatment of elderly patients with osteoporotic thoracolumbar fractures. METHODS: A retrospective analysis was performed on 62 patients with osteoporotic compression fracture of single-vertebral thoracic or lumbar segment who underwent PKP surgery and had a bone density less than or equal to -3.0 SD from February 2016 to December 2016. Among them, 23 patients were in CPC/PMMA group, with an average age of (77.6±2.2) years old, 39 patients in PMMA group, with an average age of (77.1±1.1) years old. The indexes between two groups were compared, including the visual analogue scale (VAS), height ratio of anterior vertebra (AVHR), local Cobb angle, cement leakage, new adjacent vertebral fracture(NAVF). RESULTS: There were no significant difference in gender, age, follow-up time and preoperative VAS, AVHR, local Cobb angle between two groups (>0.05), at the 1 day after operation, VAS, AVHR, local Cobb angle in all patients got obvious improvement (<0.05), which was no significant difference at 1 day after operation and final follow-up (>0.05). At the same time, there was no statistically significant difference in the incidence of new adjacent vertebral fracture and cement leakage (>0.05). The pain in both groups continued to improve at follow up after operation (<0.05), the local Cobb angle increased (<0.05) and AVHR decreased slightly (<0.05). However, the images of conventional methods (X-ray or CT) could not find signs about CPC degeneration and new bone ingrowth. CONCLUSION CPC/PMMA composite bone cement is safe and reliablein PKP for treatment of elderly patients with osteoporotic thoracolumbar fractures, which can effectively relieve pain and maintain vertebral body stability. It has the same curative effect as PMMA bone cement. It was worthy to research more in future, although no direct evidences support the CPC/PMMA composite bone cement can reduce the incidence of adjacent vertebral fracture, CPC degeneration or new bone ingrowth.
