Objective To analyze the factors related to the disqualification of urine routine and stool routine, and to formulate corresponding solutions. Methods In April 2014 to April 2017 our collected 600 cases of hospitalized patients, urine and stool samples for routine detection, made clear that cause unqualified samples related factors, and develop effective solution strategy. Results 600 cases in the selected routine urine, excrement and urine routine test specimens, the unqualified samples of total 110 cases, fraction defective is 18.33%, 490 qualified samples, percent of pass is 81.67%, the difference was statistically significant (P<0.05).There are a number of factors that cause the sample to fail, such as the contamination of the sample, the length of storage, the operation and the preparation. Conclusion In the process of actual diagnosis of disease, clinical result in urine, feces routine test specimen unqualified often appear, the reason is to a great extent, and the related nursing staff in urine and stool samples of patients before the lack of relevant guidance and so on, and nursing staff after the complete collection of specimens does not usually in accordance with the relevant standard of serious check, to avoid the sample inspection is unqualified, hospitals need to develop scientific inspection process, nurses in practice need to strict adherence to the process, and through intensive training, promote nursing staff awareness test, can to improve the qualification rate of sample test provide strong guarantee.

Objective To study the effect of salmon calcitonin and physical therapy on lumbar spinal ste- nosis.Methods Eighty cases of lumbar spinal stenosis were divided into treatment and control groups.Physical therapy alone was given to the control group,but salmon calcitonin was injected intramuscularly in addition to phys- ical therapy for the patients in the treatment group.Visual analogue scale,range of motion (ROM),pain-free walking distance,tendon reflexes and functional independence measures (FIM) were observed to assess the re- sults.Results The VAS,ROM and walking distance of the treatment group improved more than those of the con- trol group,but the groups' tendon reflexes and FIM were similar.Conclusions Salmon caleitonin can reduce the symptoms of lumbar spinal stenosis,and it has special effects in relieving pain.

Ribosome inactivating protein(RIP) is a kind of toxin plant pr ot ein in which extensively lives in the body of higher plants and controls ribosom e's function. Beside it can control protein's combination,it has lots of biolog ical reactivity as resisting giving birth and tumor and controlling HIV. At fir st, RIP is isolated from seeds of bitter melon.The result of SDS-PAGE indicate s that there are lots of RIP in the abstraction liquid.Then we study the antivi ral action of RIP through the cell of CEF and SPF chicken embryos.The results s how that RIP can resist NDVF_48E_8,MDVCVI_988 and FPV-SD4 to so me extent.

BACKGROUND: Acute kidney injury (AKI) is associated with a high mortality. This study was undertaken to detect the factors associated with the prognosis of AKI. METHODS: We retrospectively reviewed 98 patients with AKI treated from March 2008 to August 2009 at this hospital. In these patients, 60 were male and 38 female. Their age ranged from 19 to 89 years (mean 52.4±16.1 years). The excluded patients were those who died within 24 hours after admission to ICU or those who had a history of chronic kidney disease or incomplete data. After 60 days of treatment, the patients were divided into a survival group and a death group. Clinical data including gender, age, history of chronic diseases, the worst laboratory values within 24 hours after diagnosis (values of routine blood tests, blood gas analysis, liver and renal function, levels of serum cystatin C, and blood electrolytes) were analyzed. Acute physiology, chronic health evaluation (APACHE) II scores and 60-day mortality were calculated. Univariate analysis was performed to find variables relevant to prognosis, odds ratio (OR) and 95％ confidence interval (CI). Multiple-factor analysis with logistic regression analysis was made to analyze the correlation between risk factors and mortality. RESULTS: The 60-day mortality was 34.7％ (34/98). The APACHE II score of the death group was higher than that of the survival group (17.4±4.3 vs. 14.2±4.8, P<0.05). The mortality of the patients with a high level of cystatin C>1.3 mg/L was higher than that of the patients with a low level of cystatin C (<1.3 mg/L) (50％ vs. 20％, P<0.05). The univariate analysis indicated that organ failures≥2, oliguria, APACHE II>15 scores, cystatin C>1.3 mg/L, cystatin C>1.3 mg/L+APACHE II>15 scores were the risk factors of AKI. Logistic regression analysis, however, showed that organ failures≥2, oliguria, cystatin C>1.3 mg/L +APACHE II>15 scores were the independent risk factors of AKI. CONCLUSION: Cystatin C>1.3 mg/L+APACHE II>15 scores is useful in predicting adverse clinical outcomes in patients with AKI.

Objective:To investigate the efficacy and safety of continuous blood purification in the treatment of severe acute pancreatitis.Methods:60 cases of severe acute pancreatitis were selected and divided into two groups.The control group (29 cases) was given routine treatment and the observation group (31 cases) was given continuous blood purification.The efficacy of continuous blood purification in the treatment of severe acute pancreatitis was evaluated by CRP,ALT,PaO2/FiO2,HCO3-,Scr,APACHE Ⅱ and MODS scores before and after treatment,complications and survival situation during treatment.Results:Before treatment,there was no statistical significance in the CRP,ALT,PaO2/FiO2,HCO3-,Scr levels between two groups (P＞0.05).After treatment,the CRP,ALT,HCO3-,Scr levels of two groups were decreased.These indexes of observation group were lower than those of the control group (P＜0.05).The PaO2/FiO2 of both groups were increased.The PaO2/FiO2 of observation group was high than that of the control group (P＜0.05).Before treatment,there was no statistical significance in the APACHE Ⅱ and MODS scores between two groups (P＞0.05).After treatment,the APACHE Ⅱ and MODS scores were lower than those before treatment.The APACHE Ⅱ and MODS scores in the observation group were lower than those of the control group (P＜0.05).During treatment,there was no statistical significance in the complications and survival rate between two groups (P＞0.05).Conclusion:Continuous blood purification had a good therapeutic effect on the severe acute pancreatitis.It could improve the organ function,reduce inflammation and regulate the balance of water and electrolyte with high safety.

BACKGROUND: Endoscopic transnasal lacrimal duct reconstruction by grafting of autogenous tissue is a novel method for treatment of severe lacrimal duct obstruction and it needs detailed anatomical data for surgery.OBJECTIVE: To study the applied microsurgical anatomy of lacrimal duct and to provide anatomical evidence for endoscopic transnasal lacrimal duct reconstruction by grafting of autoganous tissue.DESIGN, TIME AND SETTING: This study was performed at the laboratory of the Department of Ophthalmology, Armed Police General Hospital from July 2006 to June 2007.MATERIALS: Twenty 10% formaldehyde-treated adult cadaveric heads, 14 males and 6 females, comprising 40 lacrimal ducts were included in this study.METHODS: The cadaveric heads were split on the level of the line between the superior border of the superciliary arch and the site 10 mm higher than occipital tuberosity. After removal of brain tissue,the heads were decalcified for approximate 1 week with 10%nitric acid. This promised non-alteration of morphological structure and facilitation for surgical cutting. Following dissection of facial cranium in the median sagittal plane, the nasal septum was excised to expose the lateral wall of the nasal cavity.MAIN OUTCOME MEASURES: The anteroposterior diameter and depth of lacrimal fossa; at middle third level, the thickness of lacrimal fossa at the anterior lacrimal crest, vertical middle line, and posterior lacrimal crest; the cross section area of nasolacrimal canal upper opening, middle part, and lower opening; horizontal distance, 30° oblique distance, and 45°oblique distance from lacrimal caruncie to nasal cavity; distance from lacrimal caruncle to nasolacrimal canal upper opening; and the included angle between lacrimal caruncle-nasolacrimal canal upper opening line and Aeby's plane.RESULTS: The length, anteroposterior diameter, and depth of lacrimal fossa were (17.85±1.72) mm, (6.74+1.28) mm, and (3.09+0.78) mm, respectively. At middle third level, the thickness of lacrimal fossa at the anterior lacrimal crest,perpendicular bisector, and posterior lacrimal crest was (4.03±0.89) mm, (0.61±0.36) mm, and (0.63±0.24) mm, respectively.Anterior lacrimal crest was significantly thicker than vertical middle line and posterior lacrimal crest (P ＞ 0.05). Horizontal distance, 30°oblique distance, and 45° oblique distance from lacrimal caruncle to nasal cavity was (17.23±0.70) mm,(14.51±1.72) mm, and (17.34±2.38) mm, accordingly, with a difference which was not significant (P ＞ 0.05). The distance from lacrimal caruncle to lateral wall middle point of nasolacrimal duct superior opening was (11.86±1.84) mm, and the included angle between lacrimal caruncle-lateral wall middle point of nasolacrimal duct superior opening line and Aeby's plane averaged (49.9±1.8)°.CONCLUSION: The distances from lacrimal caruncle to nasal cavity and lacrimal sac and the included angles between lacrimal caruncle-nasolacrimal canal upper opening line and Aeby's plane provide guidance significance for selection of bony opening position on the lateral wall of nasal cavity and determinations of tunnel oblique angle and autogenous tissue length. Creation of bony tunnel should start from the middle or posterior middle part of lacrimal fossa and then extend towards anterior inferior region with an optimal downward oblique angle of 45°. The length of autogenous tissue used for lacrimal duct reconstruction should exceed 21.22 mm.

In recent years, the discovery and studies on aquaporin have made us have a more in-depth understanding about the physiological and pathological processes of water metabolism. Over years, however, there has been no quantitative study on the target sites of diuretic traditional Chinese medicines at the molecular level. In that case, aquaporin was found to been a new target molecule to explain the efficacy exertion of diuretic traditional Chinese medicines. By studying aquaporin, researchers can understand the implicit meaning of the diuretic effect of traditional Chinese medicines and conduct quantitative studies on the diuretic effect. So far, many scholars have conducted a series of studies in the traditional Chinese medicine field by using the findings on aquaporin and made certain advances. This article provides a summary about the efficacy exertion of diuretic traditional Chinese medicines through target molecule aquaporin.
