Objective To evaluate the clinical reliability and feasibility of computerized endoscopic balloon manometry in vitro and in vivo, in measurement of pressure of esophageal varices. Methods Computerized endoscopic balloon manometry was used to measure the pressure of variceal model with different diameter (3 mm, 6 mm and 8 mm) and intraluminal pressures (ranging from 8 to 36 mm Hg), and the findings were compared with actual pressures. The technique was also applied in 23 patients with liver cirrhosis and esophageal varices, and its correlation with hepatic venous pressure gradient and other factors related with varices bleeding. Results The study in vitro showed that the measured intraluminal pressure was correlated significantly with the actual value ( r ≥ 0. 993, P < 0. 001 ) without obvious measurement bias(95% CI = -0.13 cm H2O to 0. 33 cm H2O). The measurement in 23 patients were success with little variation coefficient (r≥0. 998) between repeated procedures. Regression analysis showed a good correlation between variceal pressure and hepatic venous pressure gradient (r=0. 858, P < 0. 001 ). A higher variceal pressure was strongly associated with presence of previous bleeding episodes, vascular diameter and presence of red color signs, but did not correlate with the parameter of Child-Pugh classification ( t = 0. 31, P =0. 76). Conclusion Computerized endoscopic balloon manometry is reliable and feasible to examine esophageal variceal pressure, and is very likely to be a valuable clinical index for variceal bleeding.

Objective To evaluate the role of nutritional parameters in prognosis,especially in the early and late mortality of hospital-acquired acute kidney injury (AKI) patients.Methods This study was a prospective cohort study conducted in a hospital comprising 1500 beds in Shanghai, China. One hundred ninety-four patients with hospital-acquired AKI, as determined using the RIFLE staging criteria,were enrolled as subjects after obtaining informed consent.Patients with AKI caused by postrenal obstruction,glomerulonephritis,interstitial nephritis or vasculitis were excluded.Nutritional evaluation,including subjective global assessment (SGA),anthropometric and laboratory examination,was conducted. Other laboratory measurements and clinical data were recorded.The primary outcome was early mortality (≤ 7 days) and late mortality (8-28 days) after enrolling into the study. Results AKI patients at enrollment were characterized by a high prevalence of malnutrition as determined by SGA, anthropometric and laboratory examination.Univariate analysis showed that the SGA,the serum levels of prealbumin,cholesterol and total lymphatic cells, and the Maastricht index were significantly different among early mortality,late mortality and survival groups.The serum prealbumin and cholesterol levels in the early death group were significantly lower than those in the survival and late death groups (P<0.05).Multivariate analysis revealed that SGA,albumin,prealbumin and cholesterol remained independently and significantly associated with early mortality after adjusting for age,sex,dialysis,ventilation,hemoglobin,platelets,bilirubin,and Glasgow coma score.The areas under the receiver operating characteristic curve to predict early mortality for albumin,prealbumin and cholesterol were 0.591,0.736 and 0.603,respectively,with that of prealbumin significantly higher than others (P<0.05). Conclusion Low levels of serum prealbumin,albumin and cholesterol at enrollment are independtly associated with increased early mortality in hospital-acquired AKI patients.

OBJECTIVETo explore the distribution of deep inferior epigastric perforator vessel and application of the expanded perforator flap for large scar on hand and forearm.
METHODS20 healthy adults were selected to detect the distribution of deep inferior epigastric perforator vessel. 10 cases with cicatricial constriction on hand and forearm were treated with expanded perforator flap.
RESULTS425 perforator points were detected on the skin surface of abdomen in 20 adults. 80% of the points are located within the area which is 1.1 -5.8 cm far from the mid-line of abdomen. According to the Rand method, the percentage of the points in zone I , II , III were 26%, 43%, and 30%, respectively. There were few points in zone IV. The area around navel had a high density of points. The points were distributed asymmetrically at the two sides of abdomen. 10 cases were treated. Vascular deficiency happened at the distal end of one flap. All the other 9 flaps survived.
CONCLUSIONSThe expanded deep inferior epigastric perforator flap is thin and has a large size. It is very suitable for large scar on forearm or hand.

OBJECTIVETo investigate the protective effect and mechanism of Shenqi Compound on diabetic angiopathy modeled rats.
METHODSTotally 18 SD rats were randomized into 3 groups, i.e., the normal control group, the diabetic mellitus (DM) group, and Shenqi Compound group, 6 in each group. The DM rat model was established by feeding high-fat diet (to induce hyperlipidemia) +intraperitoneal injection of small dose streptozotocin (STZ). Shenqi Compound was given to rats in the Shenqi Compound group at the daily dose of 2 g/kg. Equal volume of normal saline was given to rats in the model group and the normal control group by gastrogavage. All treatment was lasted for 12 weeks. Then 2-D and ultrasonic integrated backscatter technique were used to evaluate structural and functional changes of abdominal aorta in the progression of diabetic macroangiopathy. The fibrosis degree of the aorta vessel and myocardium capillaries were observed by using HE and Masson trichrome staining. The tension of the aortic vascular ring was determined. The transforming growth factor beta (TGF-beta) mRNA expression was detected by real time PCR (RT-PCR). The protein expression of TGF-beta, collagen I, collagen III, connective tissue growth factor (CTGF), and phosphorylation P38 MAPK were detected by Western blot.
RESULTSCompared with the normal control group, abdominal aortic systolic inner diameter, diastolic inner diameter, Peterson elastic modulus, stiffness index, and backscatter integral significantly increased; the rangeability of integral backscatter and the extension coefficient of cross section significantly decreased in the DM group (all P < 0.05). After 12 weeks aforesaid indices were obviously improved in the Shenqi Compound group (P < 0.05). Results of HE and Masson staining showed that the fibrosis degree of the aorta vessel and myocardium capillaries was obviously alleviated in rats of the Shenqi Compound group (P < 0.05). Results of the aortic vascular ring tension showed that acetylcholine induced vasodilatation and maximum diastolic percent were obviously elevated in the Shenqi Compound group (P < 0.05). Compared with the normal control group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all significantly increased in the DM group (P < 0.05). Compared with the DM group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all decreased (P < 0.05).
CONCLUSIONSShenqi Compound could effectively improve the arterial function in diabetic marcoangiopathy and microvascular dysfunction. The mechanism might be due to the down-regulating the expression of TGF-beta, and further suppressing the phosphorylation of P38 MAPK, reducing the synthesis of collagen I and collagen III, therefore, ameliorating arterial and myocardial interstitial fibrosis.
