Objective To study the variation of endothelin 1(ET 1) and calcitonin generelated peptide(cGRP) and its clinical implication, and to analyze the influence of ET 1 and cGRP on cerebral arteries hemodynamics in neonates with hypoxic ischemic encephalopathy(HIE). Methods The variation of ET 1,cGRP in cord blood and peripheral blood were prospectively observed at the time of 1 day,3 days and 7 days after birth in HIE and healthy control infants by radioimmuneassay. The cerebral arteries hemodynamics were determined immediately using color Doppler ultrasonography at 1 day after blood samples were obtained. Results (1) The following factors in cord blood and vein one day after birth in neonatal HIE and healthy controls was: ET 1(70?25)ng/L vs (38?19) ng/L ( P

Objective:To investigate the effects of laparoscopy assisted complete mesocolon resection on the stress response and immune function of patients with colon cancer.Methods:From January 2013 to January 2016,130 patients with colon cancer in our hospital were selected and randomly divided into the observation group and the control group with 65 cases in each group according to the random lottery envelopes.The observation group was treated with laparoscopy assisted complete mesocolon resection,the control group was treated with open operation.The changes of semm IL-6,TNF-α and amours of CD4+ cells,blood loss,bowel function restoration time,hospital stays and complication rate of two groups were compared before and after treatment.Results:Both groups of patients were successfully completed the surgery and there was no serious complications occurred in both groups.The amount of bleeding,postoperative intestinal recovery time and postoperative hospital stay in the observation group were significantly less than those of the control group (P＜0.05).The chylous fistula,wound infection,pulmonary infection and complication rate on the 14th day postoperation in the observation group was 1.5％,which was 12.3％ in the control group and significantly higher than that of the control group (P＜0.05).The contents ofCD4+ cells in the observation group and the control group were 36.34± 7.83％ and 33.66± 9.82％,respectively,which were significantly higher than those before treatment(30.33± 6.49％ and 30.49± 5.33％)(P＜0.05),and the contents of CD4+ cells of observation group was significantly higher than that of the control group after treatment (P＜0.05).The serum levels ofIL-6 and TNF-α in both groups were significantly lower than those before treatment on the 14th day postoperation (P＜0.05),and the serum IL-6 and TNF-α levels of observation group were significantly lower than those in the control group on the 14th day postoperation (P＜0.05).Conclusion:Laparoscopy assisted complete mesocolon resection could promote the immune function and inhibit the stress response,which further promoted the rehabilitation and induced the complications in the treatment of patients with colon cancer.

Objective To investigate the effect of continuous video EEG monitoring on acute cerebral infarction comorbid epileptiform discharges and clinical seizures,and the relationship between cerebral infarction site and seizures.Methods Of the 337 patients continuously video EEG monitored in NICU at our department,259 were included for this study according to our inclusion and exclusion criteria.We recorded patients' epileptiform discharges,type and time of clinical onset,detailed CT and (or) MRI display,cerebral infarction site,and demographic data including admission age,gender,disease history and NIHSS score.Results There were 227/259 (88％) cases showed abnormal discharge in EEG,including 94 with side hemispheric slow wave,99 with local changes,34 with slow wave combined with epileptiform discharges.Early seizures was found in 12 cases,including 3 cases with seizure-induced cerebral infarction,9 cases with attack within one week after cerebral infarction.Ten in the 12 patients had tonic-clonic seizures,and the other 2 cases hadlocal seizures.Epileptiform discharges in EEG was found in 9 cases of the 12 patients.Clinical seizures were not observed in 25 patients with epileptiform discharges in EEG.Results on the relationship between cerebral infarction site and epileptiform discharges showed that incidence of epilepsy in patients with watershed infarction was significantly higher than other types of cerebral infarction (29.0％ vs 13.4％ and 9.0％,P =0.03,0.01 ).Conclusion Continuous video EEG monitoring is capable of detecting early epilepsy and epileptiform discharges.It can provide theoretical basis for the prevention and treatment of epilepsy.

Objective:To investigate the protective effects of nuclear factor ?B inhibition on liver graft reperfusion injury during transplantation.Methods:Orthotopic liver transplantation using modified cuff technique was established in rats,animals were divided according to the grafts cold storaged in 4℃ Ringer's lactated solution with(PDTC group)or without 0.1 mol/L PDTC(control group)for 6 h.During the early stage of reperfusion,DNA binding activities of NF ?B in liver grafts were analyzed by EMSA(electrophoretic mobility shift assay),mRNA level of TNF ? and ICAM 1 by RT PCR,and activities of ALT and LDH were also detected.Results:NF ?B in liver grafts was activated at early stage of reperfusion during transplantation; PDTC treated liver displayed lower activation of NF ?B 1 h after reperfusion,whereas no difference was shown between 2 groups 6 h after reperfusion.Up regulation of TNF ? and ICAM 1 transcription,high level of ALT and LDH activities were observed in both groups during reperfusion,whereas the transcriptional up regulation and the activities of ALT and LDH in PDTC group were reduced compared with those of control group( P

Objective To evaluate the value of lung sonography in diagnosis of neonatal pulmonary diseases and to provide a reliable and simple method for diagnosing neonatal pulmonary diseases.Methods From May 2012 to August 2012,105 newborns who admitted into Bayi Children's Hospital were enrolled into this study,including respiratory distress syndrome 40 cases (three of them with difficulty in withdrawing mechanical ventilation),meconium aspiration syndrome 17 cases,wet lung of newborn 17 cases and 30 health neonates without lung diseases.Lung ultrasound was performed at bedside by a single expert physician within the first 24 h of life.All patients with neonatal lung diseases were diagnosed by clinical manifestations,arterial blood gas analysis and chest X-ray.Results (1) Lung sonography of normal neonates showed hypo-echo (black),smooth and clear hyper-echoic pleural line.A line was hyper echo too.(2) All 40 neonates with respiratory distress syndrome showed lung consolidation with air bronchograms; abnormal pleural line,disappeared A-lines,pleural effusion and alveolar-interstitial syndrome.Five out of the 40 (12.5％)infants showed pleural effusion.(3) All 18 meconium aspiration syndrome infants showed focal lung consolidation under pleural membrane,alveolar-interstitial syndrome,atypical changes of abnormal pleural line and disappeared A-line in lesion area with lung sonography.(4) All infants with wet lung of newborn (100.0％,17/17) showed double lung point,with which all wet lung of newborn could be diagnosed.(5) Differential diagnosis of respiratory distress syndrome with wet lung of newborn:five infants with severe dyspnea showedwhite lung in X-ray and were diagnosed as respiratory distress syndrome,while sonography only showed severe lung edema and one infant showed pleural effusion which was in accordance with wet lung of newborn,so was their courses of disease.(6) Three cases of respiratory distress syndrome showed dyspnea after withdrawing mechanical ventilation,and lung sonography showed local atelectasis but normal in X-ray.Conclusions Lung ultrasound has many advantages,such as accurate,reliable,no radiation damage,low-cost and simple; therefore,it is feasible in neonatal ward.

Objective To monitor the protective qualities of personal protective appliances and to ensure the health and safety of radiological working personnel.Methods The lead-equivalent thickness of personal protective appliances and materials was measured by means of standard lead slices.The lead equivalent thickness represents in terms of mm Pb.Results 77 pieces of products and samples were measured altogether.The results indicate that the specific lead equivalents of lead-rubber plates were between 0.20-0.39 mm Pb/mm for 37 pieces of lead-rubber plates and the values of 6 pieces of samples were less than 0.25 mm Pb/mm,which did not accord with the requirement of the relational standard.27 pieces of personal protection appliances were measured altogether.They were 12 pieces of protective clothes,4 pieces of protective headgears,5 pieces of protective neckpieces,4 pieces of protective gloves and 2 pieces of protective masks.13 pairs of lead-glass spectacles among them were measured altogether.The measured results for personal protective appliances and lead-glass spectacles showed that actually measured lead-equivalent were higher than the nominal lead-equivalent.Conclusions The protective qualities are reliable for personal protection materials and appliances to be made in home and imported abroad.But the protective qualities of interventional protection gloves should be improved and made them better.

OBJECTIVE:To promote the rational application of antibiotics on pediatric outpatients.METHODS:Considering the fact of our hospital,taking the acute respiratory tract infection(ARI)as an example,and using retrospective document for analysis from the aspects of the dominant idea in medication,varieties of antibiotics,the ways of administration,the course of treatment and etc.RESULTS:Subjective mistakes gave rise to the abuse of antibiotics;the variety of pediatric drugs was limited by the adverse effects of antibiotics and the diversify of drug resistance;the situation of drug abuse by intravenous drop was serious; the main cause for course shortage was due to the particularity of ambulatory treatment,uncertainty of etiology and drug resistance.CONCLUSIONS:The rational application of antibiotics on pediatric outpatients can be improved by enhancing the publicity of rational drug use,writing drug administration guidance for pediatric antibiotics applicable to the local area,developing more specifications and dosage forms.

Objective To discuss the relationship between various T lymphocyte subsets apoptosis and disease progression in chronic antiretroviral-naive HIV/AIDS patients. Methods Thirty-six chronic antiretrovi-ral-naive HIV-infected individuals as well as 16 healthy HIV-negative controls were performed in this study. Ac-cording to the CD4~+ T cell counts, all the patients were divided three groups: < 200/μl, 200-350/μl and > 350/μl. After the peripheral blood mononuclear cells(PBMC) were isolated, T lymphocyte subpopulations were determined by the expression of CD45RO and CD27, and the apoptosis of different T cell subsets were measured by Annexin V staining, then analyzed by flow cytometry. To investigate whether the apoptosis of T cells varied with the culture time in vitro, 4 healthy controls and 4 patients were chosen as subjects, and the lev-els of cell apoptosis were analyzed at the culture time points of 0, 3, 6, 12, 24 h. Results (1)The percenta-ges of the AnnexinV expression on CD4~+ and CD8~+ T cells and all the subsets in HIV/AIDS patients were sig-nificantly higher than that in the healthy controls (P<0.05), but there were no significant differences among the three HIV-infected patient groups(P>0.05). (2) No significant correlations were observed between the levels of apoptosis of all the T cells and subsets and total CD4~+ T cell counts(P>0.05) ,nor with the HIV viral load (P>0.05). (3)As the culture time prolonged in vitro, the levels of apoptosis and necrosis of CD4~6 T cells in HIV/AIDS patients were significantly higher than those in the healthy conlrols, and the CD4~+ T cells were more susceptible to apoptosis and necrosis compared with CD8~+ T cells. Conclusion The levels of T cell apoptosis in HIV/AIDS patients was significantly higher than those in the healthy controls, at the same time, CD4~+ T cells were more susceptible to apoptosis and necrosis compared with CD8~+ T cells, but no correlation was found between the T cell apoptsis and disease progression.
