Objective To observe the dynamic change of cerebral blood flow of newborns with hypoxic-ischemic encephalopathy(HIE).Methods Cerebral blood flow of middle cerebral artery and pulsatility index(PI) on 75 newborns with HIE and 50 normal infants were examined with transcranial doppler sonography at different time points,and the relations between cerebral blood flow and clinic indexes were analyzed.Results The blood velocity of normal infants increased gradually, and PI decreased from 2 to 5 days.The velocities were lower than that of normal infants,and PI was higher at 12th hour and 1st day, but during 2-5 days,the velocities got higher and PI got lower, in which the decrease of velocities correlated positively with Apgar scores and the increase of velocities were negatively correlative to Apgar scores.Compared with the neonates who had poor prognosis retrospectively with those had good prognosis, the velocity changes were found to be more significant.Conclusion The change of cerebral blood flow can show the pathophysiology of HIE and prognosticate the prognosis of neonates with HIE.

Objective To observe the expression of matrix metalloproteinases(MMP)-1,MMP-3 and iNOS in cartilage of experimental rabbit osteoarthritis at different time intervals after anterior cruciate ligament transection(ACLT)operation.The aim of this study is to provide the theoritical evidence for using ACLT rabbit model in Osteoarthritis(OA)research.Methods Unilateral ACLT was performed on 27 randomly selected while rabbits and underwent unilateral arthrotomy was performed on the other 9 white rabbits as the control group.Nine randomly selected white rabbits in experimental group were killed and 3 white rabbits in the control group at 4th,8th and 12th week respectively.Cartilage degradation of femoral condyles was evaluated macr-oscopically,mRNA expression level and protein expression level of MMP-1,MMP-3 and iNOS was measured by reverse transcription-polymerase chain reaction(RT-PCR)and immunohistochemistry respectively.Results Forepart OA cartilage degradation was observed at the 4th week and became more severe at the 8th week after ACLF.Afterpart cartilage degradation was evident at the 12th week after ACLT while cartilage still remained normal in the control group,mRNA expression level and protein expression level of MMP-1.MMP-3 and iNOS were increased at the 4th week and became higher gradually at the 8th,12th week after ACLT compared with the control group.Expression distribution of MMP-1,MMP-3 and iNOS bad different patterns respectively.Conclusion It is suggested that the process of OA cartilage degradation can be simulated by ACLT model and MMP-1,MMP-3 and iNOS may be good markers in therapeutical research of OA.

OBJECTIVETo explore the rehabilitation effect of SHI's Bian stone comprehensive therapy on the patient after induced abortion.

METHODSThirty cases of induced abortion were treated with SHI's Bian stone comprehensive therapy in peri-operative period. Before the operation, scraping therapy was given at the parts of The Urinary Bladder Channel and The Governor Vessel on the back and 30 min after the operation, the patient took a rest in a horizontal position on a mild heat Bian stone blanket and hot compress with a Bian stone plate was given at the lower abdomen. They received thrice return visits respectively on 1, 2, 3 weeks after the operation and SHI's Bian stone comprehensive therapy, including warm massage on The Governor Vessel, scraping the channel, patting Baliao (BL 31, BL 32, BL 33, BL 34), penetration needling Sanyinjiao (SP 6), oblique needling Qihai (CV 6), Guanyuan (CV 4), Zhongji (CV 3), Zigong (EX-CA 1), and the Bian stone plate was placed on the needle hand for warm compress. Colporrhagia, menstrual return, soreness of waist and other symptoms after the operation were observed.

RESULTSAfter SHI's Bian stone comprehensive therapy, in the patient of induced abortion the colporrhagia volume was less within 3 days after the operation and the colporrhagia stopped more early; of the 30 cases, only 2 has soreness of waist, abdominal pain, fearing cool and other symptoms, and only one case had obviously delayed mestrual cycle.

CONCLUSIONSHI's Bian stone comprehensive therapy used in peri-operative period of induced abortion has a good promoting action on post operative rehabilitation.

Objective To discuss the meanings and methods of the screening, diagnosis and treatment of the left subclavian artery stenosis before the coronary artery bypass grafting (CABG). Methods A total of 612 patients intend to perform coronary artery bypass grafting in Tianjin Thoracic Hospital,and who were with severe stenosis or occlusion with left subclavian artery were screened by non invasive arteriosclerosis before operation. The diagnosis was confirmed by computerized tomography angiography(CTA),then the stenting angioplasty to the left subclavian artery was performed.The off-pump bypass surgery with the left internal thoracic artery(LITA)-left anterior descending artery (LAD) bypass was performed one week after operation.Results The CTA and digital subtraction angiography(DSA)confirmed the results of the left subclavian stenosis according to the non-invasive artery testing.All the 5 patients were performed with the stenting angioplasty to the left subclavian artery successfully,and the residual stenosis rate was<10%.The clinical symptoms were markedly improved after operations in all symptomatic patients,and the systolic pressure difference was<20 mmHg in two upper extremities.The blood flow was enough in LITA during the LITA-LAD bypass.The angina pectoris was improved after the operation. No coronary-subclavian artery steal phenomenon occurred. Neither stroke, myocardial infraction nor death occurred during perioperative period.All the patients were followed up for a time of 6-12 months,and the average time was about 10 months.No posterior circulation,upper limbs or myocardial ischemia occurred,and the systolic pressure difference was<20 mmHg in two upper extremities.Conclusion The non-invasion testing is of unique value in the screening of the left subclavian artery stenosis.

Objective To investigate the protective effect of methylene blue (MB) on blood-brain barrier (BBB) injury after focal cere-bral ischemia-reperfusion in rats. Methods 18 male Sprague-Dawley rats were randomly divided into sham-operated group (n=6), model group (n=6) and MB treatment group (n=6). The left middle cerebral arteries were occluded for 1 hour and reperfused. MB was infused intra-venously immediately after reperfusion (3 mg/kg) and again 2 hours post-reperfusion (1.5 mg/kg), while normal saline was administered in the model group. The sham-operated group was treated as same as the model group without occlusion and infusion. HE staining was used to observe the histological injury in the cortex around the infarcted region 47 hours after reperfusion, while albumin immunohistochemistry was used to evaluate the permeability of the BBB, and immunohistochemistry and double immunofluorescence staining were used to exam-ine the expressions of glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP-4). Results HE staining showed that cells and blood ves-sels were not intact in the cortex around the infarcted region in the model group and they were better in the MB treatment group. The expres-sions of the albumin, GFAP and AQP-4 were higher in the model group than in the sham-operated group (P<0.01), and were lower in MB treatment group than in the model group (P<0.05). The double immunofluorescence staining showed the colocalization of GFAP and AQP-4 in the astrocytes. Conclusion MB may ameliorate the BBB disruption induced by focal cerebral ischemia-reperfusion through reducing glio-cyte proliferation and down-regulation of AQP-4 expression in rats.
