OBJECTIVETo search for a method for increasing clinical therapeutic effect of acute large area cerebral infarction.

METHODSNinety-six cases were randomly divided into a comprehensive treatment group and a western medicine group, 48 cases in each group. The western medicine group were treated with routine western methods, dehydration for decreasing intracranial pressure, brain-protection, anti-platelet agglutination, improving circulation and expectant treatment, etc.; the comprehensive treatment group were treated with the routine treatment of western medicine combined with acupuncture, moxibustion and enema of Chinese drugs. The therapeutic effect was observed after treatment for 28 days.

RESULTSThe total effective rate was 68.8% in the comprehensive treatment group and 39.6% in the western medicine group with a very significant difference between the two groups (P < 0.01), and the score of the National Institute of Health's Stroke Scale (NIHSS) and the score of the Glasgow Coma Scale (GCS) in the comprehensive treatment group were better than those in the western medicine group (P < 0.001, P < 0.01).

CONCLUSIONCombined treatment of Chinese medicine and western medicine for large area cerebral infarction is better than simple western medicine, and it can significantly improve neurological defect of the patient and decrease death rate.

Objective To investigate the expression and significance of Caspase-3 and Survivin at different stages of human hemangioma in children.Methods Fifty-five specimens of hemangioma tissue excised in operation and 8 normal skins removed in operation were harvested from People's Hospital of Gansu Province between Jan.2000 and Dec.2005.The pathologic diagnosis was divided into 3 groups according to Mulliken's standard under microscope:proliferated phase group(n=31),degenerated phase group(n=24),and control group(n=8).All these specimens were examined by immunohisto for Caspase-3 and Survivin expression.Results Caspase-3 positive rate in the proliferative phase and involuting phase were 35.5% and 79.2%,respectively.The positive rate in involuting phase was higher than that that in proliferative phase,the difference between the 2 groups was significant(P=0.045 9).A significant difference was not found between the proliferative phase and normal skin tissue(P=0.057 3).Survivin positive rate in the proliferating and involuting phase were 77.4% and 45.8%,respectively.The positive rate in proliferative phase was higher than that in involuting phase,the difference between the 2 groups was significant(P=0.008 5),the difference in involuting phase and normal skin tissue was not significant(P=0.059 3).Conclusions High level of Caspase-3 expression in vascular endothelial cells in involuting phase in contrast to that in proliferative phase,which indicates that Caspase-3 may play a positive role in the apoptosis of vascular endothelial cells.Survivin may inhibit the apoptosis of vascular endothelial cells in proliferative phase due to it's high expression.Caspase-3 and Surivivin involved in the hemangioma in the regulation of apoptosis.J Appl Clin Pediatr,2009,24(1):51-52

To develop a Huntington’s disease(HD) cell model in vitro to screen drugs targeting the aggregation of polyQ,different length of CAG repeat fragments were amplified by random primer PCR, identified by DNA sequencing and were fused to the N-terminus of CAT in the pCAR system respectively which had been constructed and identified before. Recombinant plasmids were transformed into and induced to express in the host E.coli. SDS-PAGE and chloramphenicol resistance test were done to determine the solubility of the polyQ and chloramphenicol resistance levels of the fusions. With different length of CAG repeat fragments cloned and expressed in the CAT-fusion protein reporting system, it is found that when the length of the fragments increased over 40, their encoding polyQ expressed as insoluble protein and chloramphenicol resistance levels are lower, while under 40, the polyQ expressed as soluble ones and chloramphenicol resistance levels are higher. A in vitro HD model that could minimize the pathological process of the HD thus has been developed. With which by measure the recombinant bacteria’s resistance to chloramphenicol, the polyQ’ solubility and folding state in vitro by quality and quantity could be determined. Thus this model can be used to screen drugs or bioactivity materials that can inhibit aggregation of the polyQ, which thereby shedding new light on the prevent, diagnosis and therapy of HD.

Objective The present study was conducted to investigate the infection of Lyme disease, Spotted fever, Ehrlichiosis (anaplasmosisin) in wild animals and ticks in the mountain areas of Zhejiang province. Methods Nested polymerase chain reaction was used to amplify specific DNA sequences of Lyme spirochetes, Spotted fever group rickettsiae, Ehrlichia (anaplasma) from samples of mice and ticks. Results 14 positive samples were identified from 121 mice and 105 groups of ticks. Among mice samples, one positive 5S-23S rDNA intergenic spacer of Borreia burgdorferi and two 5' fragments of Ehrlichia (anaplasma) 16S rDNA were obtained. 11 positive results were detected from tick samples including three 5S-23S rDNA intergenic spacer regions of Borreia burgdorferi and eight 5' fragments of Spotted fever group rickettsiae outer member protein A gene. One group of adult ticks, Haemaphysalis longicornis, which had been collected from eastern mountain area were detected to have co-infected with Lyme spirochetes and Spotted fever group rickettsiae. The positive sequences of 5S-23S rDNA intergenic spacer and ompA gene were tested and analyzed as Lyme spirochetes while rickettsia which was closely related to Borrelia valaisiana and R. massilliae. Conclusion This was the first report about co-infection of Lyme spirochetes and Spotted fever group rickettsiae found in the same group of adult Haemaphysalis longicornis. It is very important to strengthen the surveillance program on tick-borne infectious disease and their pathogenic in vectors, wild animals and targeted high risk groups and to differentiate the clinical manifestation and diagnosis to extend the knowledge of tick-borne infectious diseases in Zhejiang.

OBJECTIVETo study whether hypoalbuminemia after pediatric cardiopulmonary bypass (CPB) for cardiac surgery is a risk factor for postoperative acute kidney injury (AKI).

METHODSA retrospective analysis was performed on the clinical data of 1 110 children who underwent CPB surgery between 2012 and 2016. According to the minimum serum albumin within 48 hours postoperatively, these patients were divided into hypoalbuminemia group (≤35 g/L) and normal albumin group (>35 g/L). The two groups were compared in terms of perioperative data and the incidence of AKI. Furthermore, the incidence of AKI was compared again after propensity score matching for the unbalanced factors during the perioperative period. The perioperative risk factors for postoperative AKI were analyzed by logistic regression.

RESULTSThe overall incidence rate of postoperative AKI was 13.78% (153/1 110), and the mortality rate was 2.52% (28/1 110). The mortality rate of children with AKI was 13.1% (20/153). The patients with hypoalbuminemia after surgery (≤35 g/L) accounted for 44.50% (494/1 110). Before and after propensity score matching, the hypoalbuminemia group had a significantly higher incidence of AKI than the normal albumin group (P<0.05). The children with AKI had a significantly lower serum albumin level after surgery than those without AKI (P<0.05). The multivariate logistic regression analysis showed albumin ≤35 g/L was one of the independent risk factors for postoperative AKI.

CONCLUSIONSAlbumin ≤35 g/L within 48 hours postoperatively is an independent risk factor for postoperative AKI in children after CPB surgery.
