Objective To investigate the stability of control preparation of blood cells after un-sealing. Methods One vial of red blood cell control preparation was aliquoted in fifteen round bottom centrifuge tube with covers stored at 2-8 "C. Aliquots were tested respectively in modes of whole blood and pre-dilution each day. The test results were filled in the quality control chart. The quality control i- tems included hemoglobin (Hb), mean cell volume (MCV), hematocrit (HCT), white blood cells (WBC) ,red blood cells (RBC) and platelets (PLT). The stability of the blood cell control preparation was also dynamically observed for 15 days with a non-aliquot standard preparation. Results There were no significant differences in the test results among the aliquots tested from day 1 to day 15. The PLT count was significantly increased for the non-aliquoted vial on day 7 (P<0.05). The coefficientvariation (CV) of test results for pre-dilution specimens was 1.3 to 5.5 times as that for whole blood specimens. Conclusion The aliquots of blood cell control materials has the potential to remain viable for at least 15 days under the temperature of 2 ℃-8℃. The whole blood dilution method has preferable reproducibility and accuracy.

Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

Objective To study the correlation between serum hepatocyte growth factor and Urinary viable tubular cells count in patients with acute renal failure and to evaluate the clinical significance.Methods Serum HGF levels were determined by ELISA and the number of viable tubular cells in urine was determined by trypan blue in 25 patients with ARF at the stages of oliguria,polyuria and convalescence.The relationship between serum HGF levels,the number of viable tubular cell and renal function was studied.Results Compared with the 9th day from the occurrence of ARF,the HGF levels in the serum increased significantly at the 1th day in the ARF patients.There was significant positive correlation between BUN or SCr and the serum HGF in urine in patients with acute renal failure.Conclusion Serum HGF in ARF patients increased significantly and tended to rise at first but dropped afterwards,which reflected the course of renal injury and the recovery of renal epithelial cells.The detected viable tubular cells in urine were an early predictive indication of renal function recovering in ARF patients.

Objective:To evaluate the possible role of cytokines in pathophysiology and treatment of nasal polyps.Method:The expressions of Th1-typed cytokines IFN-γ、IL-2 、IL-12 and Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 were investigated with enzyme-linked immune sorbent assay(ELISA) in 25 patients with nasal polyps.Result:There was a significant upregulation of Th2-typed cytokines IL-4、IL-5、IL-8、IL-10、IL-13 in nasal polyps compared with normal nasal mucosa, especially　IL-4 and IL-5 (3.9 times and 8.8 times higher than normal mucous respectively) while the expression of Th1-typed cytokines IFN-γ、IL-2、IL-12 drcreased after treated with local glucocorticoid. The levels of Th2-typed cytokines decreased significantly and Th1-typed cytokines had no obvious change.Conclusion:The upregulation of Th2-typed cytokines such as IL-4、IL-5、IL-8、IL-10、IL-12 may play an important role in the pathophysiology of nasal polyps and Th2-typed cytokines can be viewed as a target of treatment to nasal polyps.

Objective To evaluate the relationship between post-stroke urinary incontinence(UI)and 1 year stroke outcomes.Methods One hundred and thirty consecutive cerebral stroke survivors were classified into 2 groups according to their incontinence status at 1 to 10 d after onset.The patients'baseline characteristics,1 year mortality rate,abilities in the activities of daily living(ADL)and Modified Rankin Scale(mRS)scores were compared.Multivariate analysis was applied to highlight UI risk factors and correlations between UI and 1 year outcomes.Results Total anterior circulation syndrome(TACS)numbers and National Institutes of Health stroke assessment (NIHSS)scores in the UI group exceeded significantly those in the non-UI group,and both were significantly associated with initial UI.The 1 year mortality rate,patients'ADL dependence and mRS scores in the UI group exceeded those in the non-UI group significantly.Initial UI was also significantly associated with the 1 year outcome independently,as well as with age＞75 years,Oxfordshire Community Stroke Project(OCSP)classification and initial NIHSS score.Conclusion UI is common in the patients with TACS and higher initial NIHSS scores.Initial UI predicts a poor 1 year outcome,SO treatment should be strengthened.

Objective To investigate the distribution of the prevalence of albuminuria in elderly population of a community in Tianjin and analyze the situation of their early renal injury and its clinical and environmental risk factors.Methods The morning spot urine sample and the clinical data from 2 050 old population (aged ≥ 60 years)who took part in healthy examination were collected.The concentration of urine albumin and creatinine were tested,and the albumin/creatinine ratio(ACR)was calculated.We analyzed the prevalence of albuminuria,and used logistic regression to analyze the odd ratio(OR) of risk factors.Results In the 2 050 participants,the prevalence was 1162 cases (56.69％) for hypertension,264 cases (12.86％) for diabetes and 568 cases (27.71％) for albuminuria.The prevalence of ACR ＞ 30 mg/g was lower in men than in women (21.61％ vs.32.55％,P＜0.001).The OR for increased ACR was 1.45 in 70-79y subjects as compared with 60-69y subjects,and the OR was 1.89 in ＞80y old people.The OR of increased ACR was 2.03 in ＞80y old people after adjusting gender.Body mass index and waist circumference were not the risk factors of increased ACR after adjusting confounding factors.There was an association between the prevalence of albuminuria and triglycerides(OR=1.19),hypertension(OR=1.68),diabetes(OR=1.95).ACR value was increased along with increased number of cigarettes,however,there was also no association between smoking and albuminuria(P＞ 0.05).Physical activity could reduce the risk of albuminuria,the OR of ACR＞30 mg/g in those undertaking a activity once daily was 0.52 (P =0.027) Conclusions There is a high prevalence of albuminuria in elderly population(higher in female than in male) in a community of Tianjin.Hypertension and diabetes have the greatest influence on ACR.Additionally,the physical activity once daily can reduce the risk of albuminuria.

Objective To investigate the effect of arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage. Methods 156 cases diagnosed with moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage were collected from October 2011 to October 2014. Lysholm knee score and preoperative examinations such as anteroposterior, lateral, axial radiographs, the standing full leg length X-ray film and MRI scan of the knee were recommended to definitively understand the osteoarthritis staging and meniscus injury grading. All patients were treated with arthroscopic debridement and meniscectomy. After operation, physical rehabilitation exercises and regular clinical follow-up were carried out as planned. The Lysholm knee score data from preoperation and terminal follow-up was statistical analyzed. Results No patient experienced any perioperative and postoperative complications. Statistical analysis showed that the Lysholm knee score of postoperation was significantly higher than that of preoperation [(87.3 ± 7.9) vs (67.5 ± 4.9), P < 0.05). Conclusion Arthroscopic debridement and meniscectomy in treatment of moderate or severe meniscus injury combined with knee osteoarthritis in early or middle stage, gains beneficial effects for its minimal invasion and quick recovery.

OBJECTIVE: To systematically evaluate the efficacy and safety of leukotriene receptor antagonist (LTRA) combined intranasal corticosteroids in the treatment of allergic rhinitis (AR). METHOD: The randomized controlled trials (RCT) about the combined therapy of LTRA and nasal corticosteroids from January 1985 to May 2014 were searched in OVID, PubMed, EMBASE, CNKI, WanFang Data, and Cochrane Library. Two reviewers independently screened the literatures, extracted the data, and evaluated the methodological quality. Then meta-ana- lyses were conducted by using RevMan 5.1 software. RESULT: A total of 5 RCTs were included upon literature search. The results of meta-analyses showed that the efficacy of nasal corticosteroids plus LTRA was superior to nasal corticosteroids alone in total nasal symptom scores and individual nasal symptom scores (rhinorrhea, sneezing) [WMD = -4.49, 95% CI (-4.95(-)-4.03)-, P < 0.01; WMD = -0.43, 95% CI (-0.78(-)-0.07), P < 0.05; WMD = -0.10, 95% CI (-0.6(-)-0. 04), P < 0.01], with significant differences. However, compa- ring the subgroup treated with nasal corticosteroids combined LTRA against the subgroup treated with nasal corti- costeroids alone, we found no significant differences for RQLQ score and for individual nasal symptom scores (nasal blockage, nasal itching) [WMD = -15.19, 95% CI (-55.37(-)-25. 00), P > 0.05; WMD = 0.01, 95% CI(-) 0.06-0.08), P > 0. 05; WMD = -0.15,95% CI (-0.43(-)-0.13), P > 0.05]. CONCLUSION Based on limited evidence, we preliminary concluded the combined therapy of nasal corticosteroids and LTRA was more effective than nasal corticosteroids alone in the management of AR. Further large-scale, well-designed RCTs were still required to validate the add-on efficacy of LTRA for AR patients.
