Objective To investigate the gradient changes of bilateral cerebral hemisphere pressure after lateral hemisphere injury and observe their effects on craniotomy. Methods Twenty-four patients with cerebral contusion and subdural intracerebral hematoma were included in this study. All patients received brain parenehyma pressure (BPP) monitoring by introducing optic fibro sensor into each cerebral hemisphere via the frontal lobe. All patients underwent surgical craniotomy for evacuation of space occupying lesions such as cerebral hemisphere contusion, subdural and/or intracerebral hematoma.Preoperative and postoperative BPP data at different time points were recorded and analyzed. Results Preoperative BPP value of the injured hemispheres was significantly higher than that of the other hemisphere (P ＜ 0. 01 ). There was no significant statistical difference upon BPP value at 0, 24 and 48 hours after operation between both hemispheres ( P ＞ 0.05 ). The postoperative BPP value of bilateral hemispheres was lower than the preoperative one. Conclusions BPP monitoring sensors should be introduced into the injured hemisphere so that the valuable information can be timely showed. When the cerebral hemisphere has lesions after brain injury, such lesion becomes the source of elevated intracranial pressure and can result in bilateral hemisphere pressure gradient. Craniotomy can not only effectively lower the intracranial pressure, but also eliminate the BPP gradient, which contritbutes to reposition of the oppressed brain tissue.

Objective To investigate effect of lipid emulsion on cardiac arrest induced by bupivacain intoxication.Methods Forty SD rats were randomly devided into 2 groups.Group A applied epinephrine (n=20);Group L applied lipid emulsion combinding epinephring(n=20).The rats were administered Lupivacaine 20 mg/kg.Cardiopulmonary resuscitation(CPR) was started. Epinephrine 10 μg/kg were repeated three times followed by epinephrine 10 μg/kg every 5 minutes.Normal saline 5 ml/kg and 1 ml·kg-1·min-1 were administered in group A.20% Lipid emulsion 5 ml/kg and 0.25 ml·kg-1·min-1 were administered in group L.Heart rate,blood pressure, temperature were monitored.Blood gas analysiswere checked at 5 min,30 min after restoration of spontaneous circulation(ROSC).To record the number of successful CPR,time of ROSC and epinephrine dose.Results 11 rats(55%) and 16 rats(80%) were successful resuscitated.The success rate was higher in group L than in group A.Epinephrine dose was higher in group A than in group L.There was no difference in heart rate between the two groups.Systolic blood pressure and PaO2 was higher in group L than in group A(P<0.05).Conclusion There was better effect in lipid emulsion combined epinephrine than soly epinephrine when applied in cardiac arrest induced by bupivacaine intoxication.

Objective:To explore diagnostic value of nocturnal ST-T changes in 24h dynamic electrocardiogram (DCG)for coronary heart disease (CHD)and its clinical significance.Methods:A total of 103 cases,who showed ST-T changes in 24h DCG,received selective coronary angiography (CAG).Among them,the 56 patients with in-termittent nighttime significant ST-T changes were regarded as research group,while the other 47 patients with per-sistent ST-T changes were treated as control group.CAG results were compared and analyzed between two groups. Results:Compared with control group,there were significant rise in CAG positive rate (31.9% vs.67.9%),inci-dence rates of dyspnea and chest pain (27.7% vs.66.1%),hypertension (48.9% vs.71.4%),hyperlipidemia (31.9% vs.42.9%)and diabetes mellitus (17.0% vs.46.4%),percentages of lesions in left anterior descending artery (LAD,21.3% vs.57.1%),left circumflex coronary artery (LCX,14.8% vs.37.5%)and right coronary artery (RCA,12.8% vs.35.7%)in research group,P <0.05 or <0.01. Conclusion:Nocturnal ST-T signifieantly changes in 24h DCG,it possesses more diagnostic value for CHD,which can be regarded as a more sensitive index diagnosing myocardial ischemia.

Epiretinal membrane (ERM) is a relatively common macular disease that forms along the surface of the internal limiting membrane (ILM) of the retina to some reason.The pathogenesis is not clear.Microincision vitrectomy surgery has been confirmed as a minimally invasive and very safe modality of treatment.Deciding when to perform a vitrectomy can be difficult.There are many factors which can affect the postoperative visual acuity,such as age,the thickness of macular,integrity of photoreceptor inner segment/outer segment (IS/OS) junction.

Objective To learn the damage on infants and effect of treatment of congenital cytomegalovirus(CMV) infection and non-congenital cytomegalovirus infection which included perinatal infection and postnatal infection.Methods According to the diagnosis standard of cytomegalovirus infection in China,46 infants diagnosed CMV infection were retrospectively reviewed.In this research,CMV infection was diagnosed if serum CMV-IgM or CMV-pp65 in polymorphous leukocytes was positive.According to beginning time of CMV infection symptom,46 cases were divided into 2 groups: congenital infection and non-congenital infection,clinical features of 2 groups were compared.Ganciclovir was given to the infants with infantile hepatic syndrome of 2 groups,and compared liver transaminases and bilirulin with itself after treatment,side-effect was observed.Infants of 2 groups were followed up,and prognosis was compared.Results In 46 infants,21 were enrolled congenital infection group,25 were non-congenital infection group.CMV-IgM was positive in 38 cases of 46 patients,CMV-pp65 was positive in 19 cases of 43 patients,both CMVIgM and CMV-pp65 were positive in 11 cases.More congenital malformation were found in congenital group than non-congenital group,there was significant difference between 2 groups((P

OBJECTIVETo investigate the effects and mechanisms of Yishen Huoxue decoction (YHD) on chronic renal failure (CRF) rats induced by 5/6 nephrectomy.

METHODSThe glomerulosclerosis model was established by 5/6 nephrectomy in rats. Experimental animals were allocated into the normal group, the model group, the YHD group and the benazepril group. Urine protein of 24 h (UP) at the 6th and 12th weekend after operation, blood urea nitrogen (BUN) and creatinine (SCr), albumin (Alb) and haemoglobin (HB) at the 12th weekend were measured, renal pathology changes were examined with light microscope, the expressions of proliferating cell nuclear antigen (PCNA) and fibronectin (Fn) were examined by immunohistochemistry and mRNA expressions of connective tissue growth factor (CTGF) and plasminogen activator inhibitor-1 (PAI-1) by RT-PCR at the 12th weekend.

RESULTSCompared with those in the normal group, the levels of UP, BUN and SCr, the area of glomerular mesangial matrix, the FN deposition, PCNA expression in glomeruli and tubular interstitium and mRNA expressions of CTGF and PAI-1 were all significantly higher in the model group (P < 0.05). All the above-mentioned indexes were lower in the YHD group than those in the model group (P < 0.05). PCNA positively expressed cells in glomeruli of the normal, model group, YHD group and benazepril group was 7.00 +/- 2.24,34.78 +/- 6.96,15.75 +/- 2.61 and 15.50 +/- 2.57 respectively, positively correlated to the expression of CTGF, PAI-1, FN and SCr level.

CONCLUSIONYHD could delay the progression of CRF in 5/6 nephrectomized rats, and the mechanisms were mainly related to the inhibition on renal cell proliferation and it induced over-expression of cytokines, and accumulation of extracellular matrix.

Objective To assess mucin gene expression in Barrett's esophagus.Methods Mucin core protein-MUC1,MUC2,MUC3,MUCSAC and MUC6 were detected by immunohistochemistry.The re- lationship between mucin expression and magnification-endoscopic characteristics,pathohistologic epithelial types of Barrett's esophagus was analyzed.Results Mild expression of MUC1 was predominantly found in the superficial epithelium of both gastric and specialised intestinal metaplasia.In a small number of specimens, mild expression of MUC1 was also noted in glands.Strong MUC2 expression was noted only in the goblet cells in Barrett's oesophagus.MUC3 was expressed in the superficial columnar cells of specialized intestinal metaplasia with or without globlet cells but not in gastric metaplasia of the oesophagus.In some specimens MUC3 was expressed in the vacuolus of the globlet cells and the lumen of gland.Strong staining of MUCSAC was noted in the columnar epithelium of both gastric metaplasia and specialized intestinal metaplasia in Barrett's oesophagus,as well as expressed in the cytoplasm and vacuolus of the globlet cells in some speci- mens.Expression of MUC6 protein was detected at the basement of the crypts in gastric metaplasia and spe- cialised Barrett's glands.Expression of MUC2 and MUC3 protein was found much higher in villous or irregu- lar pit pattern than that in dot or rod pit pattern(P

Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in Hanchuan City marshland and lake endemic regions . Methods The data of comprehensive schistosomiasis control in Hanchuan City from 2004 to 2013 were collected and the change trends of the Oncomelania hupensis snail status and the in?fection situation of human and livestock were analyzed to evaluate the control effect. Results After the implementation of the comprehensive measures the infection rates of residents and cattle decreased from 6.38%and 8.11%in 2004 to 0.16%and 0 in 2013 respectively. There were no acute schistosomiasis patients since 2007 no new infection cases since 2011 and no infected snails since 2012. Compared with 2004 the occurrence rate of frames with living snails and the average density of living snails decreased by 56.78%and 68.35% respectively but the snail area and susceptible area increased by 0.62%and 7.10% respec?tively. In 2013 all the 367 endemic villages in 26 townships reached the criteria of transmission controlled. Conclusions The comprehensive schistosomiasis control measures based on infection source control can control the schistosomiasis transmission effectively in marshland and lake endemic regions. When consolidating the achievement the snail area in inner embankment should be compressed to prevent the schistosome re?infection in human and livestock.

Drug reservation wag investigated in 2077 community residents.We found that most drugs were obtained from the hospitals(83.78%),kept at a relatively lower place(69.23%),packed in box(75.25%),and did not meet the storage requirement(72.60%).Half of the overdue drugs(median time,12 months)were used for internal treatment.This study suggests that there might be unsafe drug storage in communities.
