Poly (ADP-ribose) polymerase-1 (PARP-1) is a ribozyme that widely exists in the cukaryotic cells.It plays important roles in the maintenance of genomic stability and the regulation of gene transcription and other physiological processes.PARP-1 is overactivated after ischemic brain injury,and PARP-1 gene knockout mice or PARP-1 inhibitor can reduce brain injury in a variety of models of cerebral ischemia.Therefore,PARP-1 plays important roles in the pathophysiologic processes of ischemic brain injury.The investigation of the effect of PARP-1 in cerebral ischemia contributes to further understanding the pathophysiologic mechanism of stroke and finding a new therapeutic target.

Objective: To study the effects of hyperbaric oxyge(HBO) in the treatment of periodontitis.Methods: 60 Guinea pigs were divided into 3 groups, 20 animals each group: ①Experimental periodontitis was induced by silk suture and feeding with the food containing 100 g/L of sugar and then exposed to 0.25 MPa of HBO for 60 min once a day when periodontitis established; ② the other 20 animals were simillary treated to group ① but not exposed to HBO; ③ another 20 animals were used as controls. HBO treatment was conducted for 2 weeks. Samples of periodontal tissues were obtained 0,4,8 and 10 weeks after treatment and prepared for histopathological study and electron microscopic observation.Results: In the treated group there were fewer macrophages in gingiva and periodontal ligment, more blood vessles, less absorption of alveolar bone, more osteoblasts and more osteogenesis in the bone. There were fewer metochodria and rough endo reticulum in plasmacytes, macrophages and osteoclasts; and more in fibroblasts, endothelial cells of blood vessles and osteoblasts. Conclusion: HBO may improve blood supply, inhibit macrophage and bone absorption.

Objective Cavernous hemangioma of infant was reported as an obscure diagnosis with the different sensitivity to corticosteroid therapy and various natural courses. Therefore, a clinical studies for the biological classification of deep subcutanious vascular lesions might be needed, which was alluded by Mulliken two decades ago. Methods Infants with cavernous hemangiomas accepted normal system corticosteroid therapy during the first 6 months of life before eight-year-follow-up, which continued until the children were 9 to 10 years old. The expression of PCNA and bFGF, and cellular histological characteristics were observed in 12 cases by biopsy. Results There were two major categories of subcutaneous vascular lesions groups: deep capillary hemangiomas, a lesion regressing slowly, and venous malformation, a lesion growing commensurated with the child. They will be also distinguished on the basis of diverse final treatment results, expression of cellular markers, microscopical characteristics, and physical signs. Conclusion The new classification appears to be helpful to make the choice of therapy for infants with "cavernous hemangiomas" , which is proven to be a terminologic confusion.

Objective To explore the effect of home-based rehabilitation on cerebral palsy.Methods 60 children with cerebral palsy were assigned to hospital-based rehabilitation group and hospital-home-based rehabilitation group and treated for 1 year.Every child was evaluated before and after the treatment with Bayley Scales of Infant Development(BSID).The Mental Development Index(MDI) and Physical Development Index(PDI) were compared between these two groups.Results After one year,the MDI and PDI improved in both groups(P<0.05),while those of the hospital-home-based rehabilitation group was better than of the hospital-based rehabilitation group(P<0.05).Conclusion Home-based rehabilitation plays an important role in the rehabilitation of cerebral palsy children.

Objective To conduct the diagnostic treatment in the children under 5 years old with suspected asthmatic disease and to evaluate its safety .Methods The children outpatients with suspected asthmatic diseas were selected and divided into the experi‐mental group and the control group according to odd days and even days .The conventiona therapy of anti‐infection ,relieving cough , reducing sputum and supporting treatment were administered in both groups .The experimental group was added tulobuterol tape . The cough relieve on daytime and nighttime ,initial effective time ,cough disappearance time and occurrence rate of adverse events at 24 ,72 h and on 5 d after treatment were compared between the two groups .Results The total effective rate of cough sysmptom re‐lief in the experimental group at 3 time points and nighttime was higher than that in the control group with statistical difference be‐tween the two groups(P < 0 .05) .The initial effective time had no statistically significant difference in daytime between the two groups(P> 0 .05) ,but which in daytime showed the statistically significant difference (P < 0 .05) ,especially the cough disappear‐ance time at nighttime in the experimental group was significantly shortened than that in the control group( P < 0 .05) .The oc‐curence rate of adverse events had no statistical difference between the two groups(P > 0 .05) .Conclusion Tulobuterol tape by transdermal delivery as one of diagnostic treatment measures for children under 5 years old with suspected asthmatic disease is defi‐nitely effective ,safe and convenient in application with the high compliance for children patients and acceptability by the family members ,obviously shortens the course of treatment ,which is worthy of being promoted .

Objective To investigate the effect of transcutaneous electric acupoint stimulation (TEAS)of Hegu-Neiguan-Houxi-Zhigou for preventing postoperative nausea and vomiting (PONV) in patients undergoing thoracoscopic lobectomy.Methods Sixty-four ASA physical status Ⅰ-Ⅲ pa-tients,aged 18-75 years,scheduled for elective thoracoscopic lobectomy were enrolled.Patients were randomly allocated into two groups (n =32):TEAS group (group E)and sham TEAS group (group C).TEAS at Hegu,Neiguan,Houxi and Zhigou was applied to patients before,during and after sur-gery in group E.The frequency was 2/100 Hz and the intensity was 2 times the threshold of sensation before and after surgery,and 30 mA during surgery.While sham TEAS with the intensity of sensory threshold was given to patients before and after surgery in group C.Patients in both groups received sufentanil,propofol and rocuronium for induction of anesthesia.Target controlled infusion of propofol and remifentanil was administered for maintenance of anesthesia.Patient-controlled intravenous anal-gesia (PCIA)was applied in both groups.No antiemetic was given to patients before and during sur-gery.Frequency of nausea or vomiting and any use of antiemetic for remediation were recorded after surgery.The postoperative Visual Analogue Scale (VAS)score and analgesic dosage were also docu-mented.Results Compared to group C,the incidence of nausea immediately after surgery,6 h after surgery,24 h after surgery and 48 h after surgery were significantly lower in group E.The incidence of vomiting 24 h after surgery was significantly lower in group E.The VAS score 6h and 24 h after surgery were significantly lower in group E.The analgesic dosage 48 h after surgery were reduced in group E.There were no significant differences regarding the use of antiemetic for remediation between the two groups.Conclusion TEAS at Hegu-Neiguan-Houxi-Zhigou is effective for preventing PONV in patients undergoing thoracoscopic lobectomy.
