Objective:To find out the impacting factors in uncertainty by analyzing the measurement uncertainty in the determina-tion of irbesartan tablets by HPLC and provide the evidence for the measurement evaluation. Methods:A mathematic model for calcu-lating uncertainty was established, and every component in the uncertainty was assessed. Results:The expanded standard uncertainty for the HPLC determination was 2. 4%. Conclusion:The measurement uncertainty of the experiment is mainly caused by the measur-ing method.

Gastrointestinal motility disorders are commonly seen digestive system diseases in elderly subjects. During the process of normal aging,digestive tract experiences a series of degenerative changes,which is the foundation of many gastrointestinal motility disorders. Further study on gastrointestinal dysmotility and its mechanisms is of great significance for the diagnosis and treatment of related diseases in aging population. In this article,the advances in studies on effects of aging on motility of digestive tract( including oropharynx,esophagus,stomach,small bowel,colon and anorectum)and its mechanism researches were reviewed.

Objective To investigate the expression ofpodocalyxin(PCX) in patients with diabetic nephropathy (DN) and its clinical significance.Methods A total of 68 patients with DN were enrolled as DN group.Another 20 healthy person were selected as control group.The patients with DN were divided into three sub-groups:normal albuminuria group(＜ 30 mg/g,group A),microalbuminuria group(≥30 mg/g but ＜ 300 mg/g,group B) and macroalbuminuria group (≥ 300 mg/g,group C).The level of urinary PCX was measured with enzyme-linked immunosorbent assay.Results The level of urinary PCX,serum creatinine and blood urea nitrogen in DN group was higher than that in control group [(27.44 + 6.87) μ g/L vs.(3.52 +1.13) μ g/L,(154.82 ± 11.54) μ mol/L vs.(82.56 ± 5.71) μ mol/L,(8.79 ± 0.58) mmol/L vs.(4.23 ± 0.34)mmol/L,P ＜0.01].The level of urinary PCX in group A,B,C was (18.04 ±4.12),(23.58 ±5.43),(32.18 ± 6.05) μ g/L,and there was significant difference among three groups (P ＜ 0.05).The level of serum creatinine and blood urea nitrogen was (138.54 + 8.66),(142.16 ± 11.74),(165.13 ± 12.85) μ mol/L and (8.48 ± 0.43),(8.56 ± 0.61),(10.04 + 1.17) mmol/L in group A,B,C,there was no significant difference between group A and group B(P＞ 0.05),but there was significant difference between group A and group C,or between group B and group C (P ＜ 0.05).Conclusion The high-level expression of urinary PCX is found in DN patients,which maybe play a key role in the early diagnosis and assessment of the progression of DN.

Objective To investigate the association betweent clinical markers of N‐terminal probrain natriuretie peptide (NT‐proBNP) ,cardiac troponin I (cTnI) and C‐reaction protein (CRP) in the patients with acute respiratory distress syndrome (ARDS) caused by severe pneumonia and to reveal the pathophysiologic process of myocardial injury after ARDS .Methods Totally 33 patients diagnosed as ARDS caused by severe pneumonia were divided into 3 groups:mild group ,moderate group and severe group according to the New Berlin definition of ARDS .Arterial blood gas analysis ,NT‐proBNP ,cTnI and CRP were observed be‐fore the treatment .Statistics were used for the analyses .Results The NT‐proBNP level in the severe group was significantly higher than that in the mild and moderate groups (P<0 .01);the NT‐proBNP level in the moderate group was also higher than that in the mild group (P< 0 .05) .Besides ,the cTnI level in the severe group was significantly higher than that in the mild and moderate groups (P<0 .01);however ,the cTnI level had no statistical difference between mild and moderate groups (P> 0 .05) .The CRP level in the severe group was significantly higher than that in the mild (P<0 .05) .Moreover ,the NT‐proBNP level of 33 patients was positively associated with the both CRP and cTnI level (P<0 .05) .Conclusion The seriously inflammatory response mediates myocardial injury probably because of ARDS .Combined NT‐proBNP and cTnI testing is important for evaluating the condition of ARDS at the early stage .

The pharmacognostical study on root of An-gelica tsinlingensis K. T. Fu was reported in thispaper. The resouce, content of essential oil, mor-philogical and histological characteristics of thisroot all were investigated. Active components con-taining in the root were examined by TLC. The re-sults of the study mentioned above has also beencompared with that of Angelica sinensis (Oliv.)Diels. 8 common metal elements (Pb, Cr, Cu,Zn, Mn, Fe, Mg, Ca) were alos determined byusing atomic absorption spectrophotomtry. Scien-tific evidences for usage, development and drawingup quality standard of Angelica tsinlingensis K. T.Fu were provided.

Objective To study the influence of gene transfer of TNFR on the tumorcidal activity of TNF. Methods By constructing retroviral expressin vector of TNFR and transfecting package cell PA317,the virus that can transfer TNFR was established.Then the virus was used to infect BIU 87 cell line.The TNFR number on tumor cell membrane and the tumorcidal activity of TNF in vitro were detected. Results The number of TNFR on cell membrane of BIU 87 cell was 912/cell and increased to 2 872/cell( P

Objective To report the experience on the modified Abb? flap for correction of mild tightness of the corrected cleft lip deformity. Methods Forty-two patients with a mild or moderately tight lip deformity after primary unilateral cleft lip repair were performed a modified Abb? flap for correcting tight upper lip. The operative technique was that the pocket was creased for the vermilion tubercle by splitting the lip. The skin was incised several millimeters beyond the vermilion-skin border and was moved laterally for a distance equal to the breadth of the vermilion tubercle. The orbicularis oris muscle and the full length of the upper lip vermilion were incised. By releasing the tension, the slight concavity, expressed in profile by the slight pout which a normal upper lip had in cross section, was obtained. The Abb? flap that was taken from the central portion of the lower lip vermilion, was designed to repair the vermilion tubercle and the Cupid's bow. The flap was approximately 8 mm in width. The full length of the lower lip vermilion and the orbicularis oris muscle were incorporated. A ting portion of skin was included, which facilitated closure of the donor site, The flap, based on the labial vessels, was rotated 180?and sutured into the created defect of the upper lip. The pedicle was divided 10 days after operation. Results Forty-two patients all showed an obvious Cupid's bow, Cupid's bow peak, the median tubercle and the height and width of the upper lip. The scarring of the base of the nose was not obvious. Conclusion Use of modified Abb? flap to reconstruct the contour of the upper lip is successful in patients with cleft lip.

Objective To explore the causes and treatment measures of hyponatremia after liver transplantation. Methods The clinical data of 27 patients with hyponatremia after liver transplantation were analyzed retrospectively. Results Among the 27 patients, postoperative hyponatremia occurred in 25 cases in about one week, and preoperative hyponatremia occurred in 2 cases and severe ~hyponatre -mia occurred immediate after operation. Acute hyponatremia occurred in one case. Blood natrium was 130 to 135 mmol/L in 10 cases, 120 to 130 mmol/L in 12 cases and less than 120 mmol/L in 5 cases. The levels of blood potassium, phosphor and calcium were all normal. Urinary natrium, potassium and chlorine levels were all normal. The ascites natrium level was higher than blood natrium at the same time. Hyponatremia was treated by supply of hypertonic saline via gastrointestine an/or veins. Conclusion Various causes could result in hyponatremia after liver transplantation. The hyponatremia was treated by supply of hypertonic saline constantly and slowly.

OBJECTIVE:To evaluate inpatients' use of antibiotics in our hospital.METHODS:The inpatients' use of antibiotics in our hospital during 2004～2006 was analyzed retrospectively in respect of the consumption sum and DDDs etc.RES-ULTS:The proportion of antibiotics in the total western medicines were decreasing year on year in terms of consumption sum.Cephalosporin,quinolones,lincomycins and penicillins had been dominated the first 4 places during the 3 consecutive years.Leading the list in terms of consumption sum and DDDs was Clindamycin injection during the 3 consecutive years.CONCLUSION:The inpatients' use of antibiotics was characterized by high starting point,excessively depending on empirical treatment,which needs to be further monitored to achieve a rational use of antibiotics.
