Objective To investigate the protective effects of hyperbaric oxygen(HBO)against brain dam- age from hypoxic ischemia(HIBD)in neonatal rats.Methods One hundred and seventeen 7-day-old Sprague- Dawley rats were randomly divided into 4 groups:a control group(n=32),a hypoxic ischemia brain damage group (HIBD group,n=30),a hyperbaric air group(HBA group,n=27),and a hyperbaric oxygen group(HBO group, n=28).The HIBD model was established by permanent occlusion of the left common carotid artery followed by expo- sure to a mixture of 8% oxygen/92% nitrogen for 2 h(at 37℃).HBO therapy was administered to the HBO group after the hypoxia exposure once a day for 7 d,as was HBA therapy to the HBA group.Apoptotic cells in the cortex and hippocampus(A_(CH)cells)were measured using TUNEL at 9 d after birth,and the ratios of left and right cerebral hemisphere weight(R_(L/R))and rate of weight gain(GRW)were recorded 14 d after birth.A radial arm maze acquisi- tion test(RAMAT)was administered at 30 to 35 days.Lastly,the neuron density in the CA_1 subfield of the rats' hip- pocampi(ND_(CAI)was measured with Nissl staining.Results R_(L/R)and GRW in the HIBD group were significantly lower than in the control group(P＜0.01),while R_(L/R)was increased in the HBO and HBA groups,especially in the HBO group(P＜0.01),although there was no significant difference in GRW between the groups.Compared with the control group,A_(CH)cells were increased and ND_(CAI)was decreased in the HIBD group(P＜0.01),while A_(CH)cells were decreased and ND_(CAI)was elevated in the HBO group in comparison with the HIBD group(P＜0.01).There was no change in A_(CH)cells or ND_(CAI)in the HBA group.The RAMAT results for the HIBD group,including the time to find the arms baited with water,average times of working errors and reference memory errors,were significantly high- er than those of the control group,while these values for the HBO group were obviously lower than for the HIBD group,and there was no change for the HBA group(P＞0.05).Conclusion HBO therapy might increase the re- covery of learning and memory function by attenuating HIBD in neonatal rats.

Objective To investigate the clinical characteristics and prognosis of patients with systemic lupus erythematosus (SLE) complicated with acute pancreatitis (AP) .Methods From January 1999 to December 2013 ,the clinical data of 16 patients with SLE complicated with AP among the total 2 526 cases of SLE was collected .A retrospective analysis was performed and the clinical data of patients was classified and documented ,which included general information ,past history ,clinical symptoms , laboratory findings ,imaging findings ,treatment and outcome .The rank sum test was performed for analysis of non‐normal distributed measurement data ,and the Fisher′s exact test was used for count data analysis .Results The incidence of SLE complicated with AP was 0 .63% (16/2 526) .Among them ,ten patients were mild acute pancreatitis (MAP) and six patients were severe acute pancreatitis (SAP) .All patients were treated with fasting ,gastrointestinal decompression ,nutritional support ,anti‐acid ,anti‐inflammatory ,glucocorticoid and somatostatin and so on . Six patients were cured , seven patients improved and three patients died (two SLE complicated with SAP ,one SLE complicated with MAP) . Compared with the SLE patients complicated with SAP ,the SLE patients complicated with MAP were more easily to have lupus nephritis(6/6 versus 5/10 ,Fisher′s exact test) ,hematological system injuries (6/6 versus 5/10 ,Fisher′s exact test) ,liver injuries (5/6 versus 0/10 ,Fisher′s exact test) ,more organs involved (mean 7 versus 3 ,Z= -3 .225) and higher SLE disease active indexes (DAI) score (mean 13 .5 versus 6 .5 ,Z= -2 .876);the differences were statistically significant (all P<0 .05) .Compared with the cured and improved SLE patients complicated with AP ,lupus encephalopathy (2/3 versus 1/13 ,Fisher′s exact test) ,more organs involved (mean 7 versus 5 ,Z= -2 .276) and higher SLE DAI score (mean 21 versus 12 ,Z= -2 .195) was more common in dead SLE patients complicated with AP;the differences were statistically significant (all P< 0 .05) .Conclusions SLE patients complicated with SAP are more easily to get lupus nephritis ,hematological system injuries ,liver injuries ,activity of SLE and multiple‐organ systems involved . The prognosis of SLE patients complicated with AP was poor in those with activity of SLE ,multiple‐organ involved and lupus encephalopathy .

Objective Aortic dissection is accute in occurrence along with fast change , which is inclined to to induce psy-chotic symptoms and affect the lives of patients .The study was to investigate the effects of healthcare cooperative intervention on pa-tients with psychiatric symptoms secondary to aortic dissection . Methods We established medical cooperation organization structure to clarify the division of responsibility along with a quick assessment form , a process chart and a green channel for emergencey treat-ment.The above method was applied to intervene 32 patients with psychiatric symptoms secondary to aortic dissection and observe the diagnosis time , the time from diagnosis to surgery , the remission time of psychiatric symptoms , the incidence of adverse events and the length of stay. Results 32 patients were diagnosed within 30min followed by emergency surgery within 30min after diagnosis, which was 1-2 hours shorter than the previous diagnosis and surgery preparation time .5-21 d after surgery , psychiatric symptoms have been effectively controlled.Extubation, falling out of bed, self-injury or injury and other adverse events did not occur .No patient died, and the average length of stay was 13.5d, which was 1.75d shorter than the length of stay of previous similar patients . Conclusion The healthcare cooperation method can quickly identify patients with psychiatric symptoms secondary to aortic dissection , prevent adverse events and shorten the length of stay .

AIM: To discuss the mechanism of hyperbaric oxygen(HBO) therapy by assessing the changes of neural stem cells(NSCs),after hypoxic-ischemic brain damage(HIBD) in neonatal rats.METHODS: Seven-day-old SD rat pups were randomly divided into 4 groups: control group(CON,n=16),HIBD group(n=16),hyperbaric air group(HBA,n=16),and HBO group(n=16).The HIBD model was produced by permanent occlusion of left common carotid artery and was exposed to a mixture of 8% oxygen and 92% nitrogen for 2 h(at 37 ℃).HBA and HBO treatment was administered by placing pups in a chamber(2 ATA for 1 h) 1 h after hypoxia exposure and performed once daily for 7 days.BrdU immunohistochemistry was used to assess how the insult had affected NSCs in the SVZ of the lateral ventricle and DG of the hippocampus.The NSCs from the ipsilateral SVZs were isolated at 3 weeks recovery from hypoxia-ischemia(HI).The number of spheres was then counted as an index of the number of NSCs residing within the SVZ.RESULTS: At 3 week survival,the SVZ of HIBD group was smaller and markedly less cellular than control group.BrdU-positive cells were dramatically decreased in the SVZ and DG of the affected hemisphere(P

AIM: To investigate whether grafting neural stem cells (NSCs) improves the impaired cognitive deficits and spatial recognition after ischemic-hypoxic brain damage (HIBD) in neonatal rats. METHODS: Non-immunosuppressed 7-day-old SD rats were used as research subject and randomly divided into 3 groups: (1) sham group (n=10); (2) HIBD group (n=11); (3) transplant group (n=13). (2) and (3) were anesthetized and subjected to a hypoxic/ischemic injury obtained by combination of left carotid ligation and exposure to 8% oxygen for 2 h. At 3 days post injury, hypoxic-ischemic brain damaged animals were re-anesthetized and randomized to receive stereotactic injection of NSCs prelabeling with BrdU or control media into the hippocampus in the ipsilateral hemisphere. Cognitive (i.e., learning) deficits were assessed at 2 to 4 weeks after transplantation. At the end of the behavioral tests, the animals were killed and evaluated for NSC survival and histopathological analysis. RESULTS: Transplant group showed significantly improved cognitive function in selected tests as compared with HIBD group during the 4-week observation period. They took less time than HIBD group in finding the 3 arms baited with water and had a decreased number of working and reference memory errors in radial maze acquisition tests. Histological analysis showed that transplanted NSCs attenuated CA1 cell loss after HIBD, and NSCs survived for as long as 4 weeks after transplantation and were detected in the hippocampus. CONCLUSION: These data suggest that transplanted NSCs attenuate brain damage and cognitive dysfunction after hypoxic-ischemic brain damage. This approach warrants continued investigation in light of potential therapeutic uses.

OBJECTIVETo make clear the burden of injury in residents living in countryside of Dongying, Shandong Province.

METHODSA retrospective questionnaire survey was conducted among 15,276 residents in 20 villages of Dongying Municipality of Shandong Province with a multiphase cluster randomly sampling on cases of injury from March 1, 2002 to February 28, 2003. The injury was decided with three principles which had been carried out through the nation. The standardized incidence and mortality rates were calculated on base of the population data of Shandong Province in 2000. The burden of injury was evaluated by incidence rate, mortality rate, years of potential life lost (YPLL) system, disability adjusted life year (DALY), direct and indirect economic costs, et al.

RESULTSTotally 902 were injured cases in which the crude incidence rate was 5.90%, and the standardized incidence rate was 5.93%. It was shown higher in men (7.79%) than in women (4.03%). The crude death rate was 12.438 per million. And the standardized death rate was 11.257 per million. 27 cases were crippled. The years, the working years and the valued years of the potential life lost were 24, 19.6 and 8.7 years respectively for each death case. Disability adjusted life years was 566.61 years. Direct economic cost for medical expenses of all cases was 816.3 thousand RMB Yuan and 200.1 thousand RMB Yuan for else costs. Indirect economic cost was 5,492.9 thousand RMB Yuan according to DALY.

CONCLUSIONInjury was common incidence in rural residents in Dongying which caused a heavy burden on them. Prevention and control of injuries would be enhanced.
