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 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 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.

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.
