Objective To study the relationship between the expression of ICAM-1,HLA-DR in the renal allograft of chronic rejection. Methods The expression of ICAM-1 and HLA-DR was assessed in 20 cadaveric renal allografts with chronic rejection using immunohistological techniqu(ABC method). Results In the renal allograft with chronic rejection,the expression of ICAM-1 was increased on the tubular epithelial cells and interstitial microvascullar endothelium,whereas the expression of HLA-DR was up-regulated,especially on the distal tubules. In addition, the expression of ICAM-1 and HLA-DR was associated with lymphcytes infiltration in the local perivascullar and intertubular structure. Conclusions It is suggested that the increased ICAM-1 and HLA-DR expressions might mediate allograft injury and have a role in the augmentation of the response,either in its induction,especially in the interstitial lymphocytes infiltration and antigen presenting or as a target for the effector arm of the reaction.

Objective　To quantify the characteristics of the auditory brainstem responses(ABR) in the normal newborns, in order to provide a data for newborn hearing screening. Methods　The ABR to click stimuli was investigated in a group of eighty normal newborns aged from 3 to 8 days and compared to those observed from the normal hearing youths. Results　Wave, Ⅰ,Ⅲ and Ⅴ were identifiable in all of 160 ears at 130 dB pe-SPL. The threshold of wave Ⅴ to click stimuli was 61.94±6.87 dB peSPL, significantly higher than that in adults. Both latencies for wave Ⅰ,Ⅲ and Ⅴ and interwaves latencies Ⅰ-Ⅲ,Ⅲ-Ⅴ and Ⅰ-Ⅴ were significantly tonger than those for the adults under identical test conditions. The ratio of interwaves latency Ⅲ-Ⅴ to Ⅰ-Ⅲ for normal newborn was 0.71±0.12, statisitically smaller than that in adults. Conclusion　Click level 70 dB peSPL appeared to be a feasible criterion of threshold of ABR for newborn hearing screening. There were no significant effects of sex and ear in newborn hearing screening. The auditory system of the newborns was not equally mature. The neurological system is the primary source of differences between newborns and adults.

Objective To observe the changes of extracellular matrix(ECM) production and hypertrophy of glomerular mesangial cells(GMCs) induced by high glucose(HG),and the inhibitory role of myriocin(ISP-1).Methods GMC cultured with normal glucose(5.6 mmol/L D-Glucose,NG),HG(25.2 mmol/L D-Glucose) and HG plus ISP-1(100 mg/L) for different durations(0,24,48,(72 h)).The sizes of GMC were indicated by forward scatter intensity,measured by flow cytometery,and the levels of fibronection(FN),collagen Ⅳ(Col Ⅳ),laminin(LN),precollagen Ⅲ(Pcol Ⅲ) and hyaluronic acid(HA) in the supernatant of cultured GMC were detec-(ted) by ELISA.Results Compared with NG,HG could induce GMC hypertrophy(P

Objective To observe whether electroacupuncture (EA) is protective to the blood-brain barrier (BBB) in rabbits with acute cerebral infarction and explore the underlying mechanisms. Methods Eighty rabbits were used in this study. After establishing the acute cerebral infarction rabbit model,all the animals were randomly allocated to a model group and an EA group. The acupoint "Bai Hui" and "Shui Gou" in Du meridian in the rabbits of the experimental group were stimulated by EA. The content of ANP,cAMP and cGMP was examined. Results Compared with the model group,the content of ANP in blood plasma and cAMP in brain tissue of the EA group significantly increased,while the content of cGMP decreased,the ratio cAMP/cGMP increased nearly to the normal level. Conclusion The EA exerted protective effect and promoted repair of BBB in rabbits with acute cerebral infarction,which might be modulated by the changes of the content of ANP in blood plasma and cAMP,cGMP in brain tissue.

Objective To study the nutritional evaluation and clinical effects of perioperative enteral nutrition (EN) versus parenteral nutrition support (PN) in elderly patients undergoing gastrectomy for gastric carcinoma.The safety,feasibility and superiority were also compared between EN and PN.Methods Totally 50 cases (aged 65 years and over) undergoing gastrectomy for gastric carcinoma in Department of Gastrointestinal Surgery of Beijing Hospital were recruited and divided randomly into two groups of EN and PN (25 cases for each).NRS2002 nutritional assessment scoring system was used to evaluate the patients.The patients in EN group were given Rui Su at 2 d before surgery,then Wei wo,Bai pu li and Rui su were sequentially given from 12 h after the surgery.The patients in PN group were received total parenteral nutrition (TPN) via central venous for 7 days.Results The average absolute lymphocytes[(1.22±0.23) ×109/L and (1.31±0.27) ×109/L vs.(1.02±0.21) × 109/ L and (1.14 ± 0.23 × 10)9/L],pre-albumin[(151.442± 48.15) mg/ L and (167.38± 46.23) mg/ L vs.(115.22 ± 47.34) mg/L and (131.27 ± 43.58) mg/L] and transferring [(1.71±0.33)g /L and (1.83±0.31)g/L vs.(1.50±0.32)g/L and (1.65±0.32)g/L,all P＜0.05] levels after surgery of 3 d and 7 d in EN group were higher than those of PN group (P＜0.05).The CRP levels at 3 d and 7 d after surgery were increased in PN group compared with EN group [(63.71±35.26)mg/L and (41.58 ± 22.55)mg/L vs.(54.26±29.13)mg/L and (18.12 ±14.35)mg/L,P＜0.05].The blood sugar and insulin levels of EN group at 3 d and 7 d after surgery were (5.93±1.12) mmol/L and (5.61± 1.03)mmol/L,(6.72±5.14) U/L and (6.21±2.63) U/L,which were decreased compared to PN group (8.31 ± 2.62) mmol/L and (8.85 ± 2.92) mmol/L,(12.81±7.26) U/L and (15.21±8.24) U/L (P＜0.05).ALT in the PN group was (38.43±18.37) U/L at 7 d after surgery,higher than EN group (23.91± 14.82) U/L(P＜0.05).The perioperative average costs of EN group was (2714.5± 1391.7) yuan,lower than PN group (5041.6± 3007.7) yuan (P＜0.05).For the patients complicated with delayed gastric emptying after surgery,nutrition cost reduction was more evident.There were no significant difference between the two groups of patients in the liver and kidney function changes and postoperative complications.Conclusions It is safe and feasible for elderly gastric cancer patients with perioperative EN sequential therapy in view of its reduced stress response of surgical trauma and insulin resistance,improvement of hyperglycemia,reduction of medical costs compared with PN for elderly gastric cancer patients.

Background Streptozotocin (STZ)-induced type 1 diabetic model is an acceptable model and is often used to the study of diabetic retinopathy (DR).However,the model is often established using retinal digest preparation in vitro in albino rats,and therefore it is difficult to evaluate the change of retinal vessels by fundus fluorescein angiography (FFA) in vivo.Recently,pigmented rats are being used as the DR model.But the study on the comparison between albino rat model and pigmented rat model is seldom.Objective This study was to observe and compare the manifestations of FFA and retinal digest preparation in early diabetic pigmented diabetic rat and albino diabetic rat,and to select the right model of DR using FFA.Methods Type 1 diabetic models were induced in 15 six-week-old health male BN rats and 15 six-week-old health male SD rats by the injection of STZ (55 mg/kg) via tail vein.The models were thought to be successful in the rats with the blood glucose level ≥ 16.7 mmol/L.The right eyes of the rats were extracted 6 weeks after injection of STZ.Lens were examined by slit lamp microscope.Retinal vascular changes were examined by fundus photography,FFA and periodic acid Schiff staining of retinal digest preparation.The manifestations of FFA and retinal digest preparation were contrasted between BN rats and SD rats.The number of eyes with lens opacification was compared by Chi-square test and the ratio of vascular endothelial cells and perithelial cells (E/P) was compared between BN rats and SD rats.The use and care of experimental animals complied the Statement of Ethic Committee of Tianjin Medicine University.Results Six weeks after injection of STZ,11 BN rats and 10SD rats were included in this study.The blood levels were (24.73±2.98) mmol/L and (22.36±3.65) mmol/L in BN rats and SD rats,respectively,without significant difference between the 2 types of rats (t =7.873,P＞0.05).Lens opacification occurred in 6 BN rats and in 5 SD rats (P=0.717).FFA showed the clear retinal vascular under the brown background.Evident vessel disorder and fluorescence leakage like background stage of DR were seen in 9 eyes.However,in the SD rats,retinal vessel abnormality could not exhibited owing to the interference of choroid fluorescent light from choroidal vessels and vortex vein.Retinal digest preparation exhibited that unevenness of vessel diameter,decrease of perithelial cells and increase of endothelial cells in both types of rats.The E/P values were 11.50±3.68in the BN rats and 12.86±3.94 in the SD rats,without significant difference between them (t=9.785,P＞0.05).Conclusions The abnormality of fundus vascular morphology can be better displayed in pigmented diabetic rats than albino rats by FFA in vivo.

Objective:To study the effect of Xihuang Capsule combined with GP regimen on the serum levels of tumor necrosis factor-oα (TNF-α),vascular endothelial growth factor (VEGF),matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) of patients with advanced breast cancer.Methods:88 patients with advanced breast cancer admitted in our hospital from March 2014 to February 2015 were selected and divided into the observation group and the control group according to the order of admission.The control group was treated by the GP program,the observation group was given Xihuang capsule combined with GP regimen.The serum levels of TNF-α,VEGF,MMP-2 and MMP-9 in the two groups were compared before and after treatment.The clinical efficacy and incidence of side effects were analyzed.Results:The total effective rate of observation group was significantly higher than that of the control group [84.09％ (37/44) vs 50.00％ (22/44)] (P＜0.05).There was no significant difference in the serum levels of TNF-α,VEGF,MMP-2 and MMP-9 between the two groups before treatment (P＞0.05).After treatment,the serum TNF-α,VEGF,MMP-2 and MMP-9 levels were significantly lower than those before treatment (P＜0.05).The serum levels of TNF-α,VEGF,MMP-2 and MMP-9 of observation group were significantly lower than those of the control group (P＜0.05).There was no significant difference in the incidence rate of nausea and vomiting between the two groups (P＞0.05).The incidence ofalopecia,diarrhea,abnormal liver function,decreased appetite,anemia and leukopenia in the observation group were significantly lower than those of the control group (P＜0.05).Conclusion:Xihuang Capsule combined with GP regimen could more effectively reduce the levels of serum TNF-α,VEGF,MMP-2 and MMP-9 of patients with advanced breast cancer than GP regime alone with higher safety.

The clinical and fundamental research for intrahepatic and extrahepatic biliary stones were still inadequate currently.It was difficult for treat and has the following clinical features:extensive he-patic lesion,complex conditions,more complications,higher recurrence rate,etc.Satisfactory results were hard to gained if just depend on conventional surgery recently.As the methods of diagnosis and treatment are continuously increasing:Ultrasound,CT,MRCP,Choledochoscope,Cholangiography and 3D imaging of hepa-tobiliary system.From the traditional open operation to a variety of minimally invasive treatment.Different examination and treatment methods has its advantages and disadvantages.How to choose the effective,less trauma,appropriate pathway method is the main direction for the current research.

Objective To investigate the feasibility,safety and efficacy of laparoscopic and endoscopic cooperative surgery (LECS) for elderly patients with gastric gastrointestinal stromal tumor (GIST).Methods 54 cases with GIST aged 65 years and over in Department of Gastrointestinal Surgery in Beijing Hospital from Dec.2008 to Dec.2012 were selected.31 cases underwent LECS and 23 cases underwent open surgery.Clinical data including operation time,intraoperative blood loss,complications,tumor size,length of incision,postoperative gastrointestinal function recovery time,postoperative in hospitalization and follow up data were retrospectively analyzed in patients.Results There were 17 males and 14 females in the LECS group,and the mean age was (72.8±5.9)years.29 patients underwent laparoscopic-assisted partial gastrectomy,and 2 cases underwent laparoscopicassisted endoscopic dissection in LECS group.All operations were successful with no conversion to open surgery and death.There were 13 males and 10 females in the open surgery group,and the mean age was(73.3±6.1)years.The mean operation time was longer in LECS group than in open surgery group [(120.6±32.8) min vs.(86.3±33.5) min].The mean intraoperative blood loss,mean tumor size,mean length of incision,mean time of gastrointestinal function recovery,mean postoperative hospitalization were less or smaller in LECS group than in open surgery group [(40±23.4) ml vs.(130±65.6) ml,(2.3±1.2)cm vs.(3.6 ±1.8)cm,(3.6±1.1) cm vs.(14.4±3.5) cm,(47.7± 10.4)h vs.(61.4±11.9)h,(5.1±2.3)d vs.(7.2±2.5)d,respectively,t=3.192,1.831,5.212,2.014,3.519,P=0.002,0.012,0.000,0.015,0.001].According postoperative tumor risk assessment,13 cases were at very low risk,15 cases at low risk and 3 cases at middle risk in LECS group; 4 cases were at very low risk,14 cases at low risk and 5 cases at middle risk in open surgery group.The risk degree was lower in LECS group than in open surgery group (x2 =5.63,P=0.017).During a follow-up of 5 53 months,death without GIST was found in 5 patients in LECS group and 4 cases in open surgery group.Hepatic metastasis was found in 1 case in open surgery group.Conclusions LECS is a safe and feasibility alternative approach for elderly patients with gastric GISTs.It has more minimal invasion,fast recovery and satisfaction with short term outcomes as compared with conventional open surgery.
