Objective To establish a rapid and sensitive method for detection of urinary protein.Methods In B-R buffer solution with pH 4.2,the signals of resonance light scattering by Poncesu S (PS) combined with protein in ?ex=?em=306nm were detected.Results There was a linear relation between the scattering signals of resonance light,and the protein concentration ranged from 0 to-1500 mg/l. The regression equation was ?I=2.24c-0.41,r=0.999 and the detection limit was 1.48 mg/l. The average recovery was 102.8% and the between-and within-subject coefficients of variation were 2.09% and 5.40% respectively.No significant difference was found compared with the method of PS.Conclusion The established method in this study is a simple,rapid and high sensitive method for determination of urinary protein.

Objective To observe the clinical efficacy of herbs by internal and external administration combined with semiconductor laser irradiation in the treatment of chronic eczema.Methods Eighty-six patients with chronic eczema were divided into the herb group and the laser group by the randomized digital table,43 patients in each group.The patients in the herb group received oral administration with Chinese herbs together with application of herbs on the affected foci.The patients in the laser group received the same treatment as in the herb group and meanwhile treated with additional semiconductor laser therapy.The clinical effects were evaluated according to their itch degree and skin lesions.Result The cure rate and total effective rate were both significantly higher in the laser group than those in the herb group(P<0.05).Conclusion Compared with herbal internal and external administration only,the clinical efficacy of herbal internal and external administration combined with semiconductor laser irradiation is more effective in the treatment of chronic eczema.

Objective To investigate the expressions of TK1 (thymidine kinase 1) in PHC (primary hepatic carcinoma). Methods TK1 and AFP in serum of 33 cases of PHC (primary hepatic carcinoma), 38 cases of hepatic cirrhosis,36 cases of hepatitis and 35 cases of healthy people were detected by means of Western blot—enhanced chemiluminecence and electrochemiluminescence. Results The difference of TK1 level in PHC group indicated significance when compared with that in hepatic cirrhosis group , hepatitis group and control group (U value was 436.4, 352.1, 163.6, respectively, all P < 0.01). TK1 level in patients with PHC was related with differentiation (χ2 = 7.476,P < 0.05) and TNM stage (χ2 = 7.227,P < 0.05),but not with sex, age, tumor diameter, number of tumors, vascular invasion, lymph node metastasis (P > 0.05). Kaplan-Meier curve analysis revealed that PHC patients with TK1≤ 2.0 pmol/L had a significantly shortened overall survival when compared with those with TK1 > 2.0 pmol/L (χ2 = 3.954,P < 0.05). Multivariable Cox regression analysis indicated that the level of TK1 and TNM stage were the independent risk factors for patients with PHC (all P <0.05). Conclusions The detection of TK1 has a certain clinical value in the diagnosis, monitoring and evaluation of the prognosis of the PHC.

Objective To investigate the CT and MRI value in diagnosis and clinical manifestations of liver tumor in child. Methods 13 cases of surgically and pathologically confirmed liver tumor were retrospectively analyzed that 11 males, 2 fe- males, age range from 13 months to 14 years, average age 10.8 years. Contrast CT was undertaken in 10 patients and MRI in 6 patients. Results In all cases comprised primary hepatocellular carcinoma 7 cases(8%), hepatoblastoma 3 cases(23%), leukemia involved liver 1 case, cavernous hemangioma 1 case, hepatic mesenchymal hamartoma 1 case. Different type of tumor had its own imaging manifestations. Conclusion CT and MRI can precisely delineate the location, size, extent of in- volvement. It provides an important basis of clinical staging for tumors prognosis and treatment.

Objective To investigate the expression of serum sHLA-G in systemic lupus erythematosus (SLE) patients and the association with the disease activity.Methods The serum concentration of sHLA-G in SLE patients and healthy controls was measured with enzyme-linked immunosorbent assay.Results Significant higher sHLA-G levels were detected in patients of SLE than control group (P＜0.01),The serum concentrations of sHLA-G in active SLE patients were markedly higher than stable SLE patients (P＜0.01).The expression level of sHLA-G showed positive correlations with SLE activity index (SLEDAI)(r=0.30,P=0.01).There was no correlation between sHLA-G levels and serum concentration of Anti-dsDNA,C3,C4 and Anti-ANA in SLE patients (P＞0.05).Conclusion The level of serum sHLA-G is significantly increased in SLE patients.Positive correlations are observed between sHLA-G levels and SLEDAI.These data indicated that sHLA-G may play certain roles in the pathogenesis and progress in SLE.

Objective To investigate the distribution and antimicrobial resistance of gram-negative bacilli isolated from wound specimens of orthopedic patients,and provide reference for the rational use of antimicrobial agents. Methods 682 isolates of gram-negative bacilli were collected from orthopedic department in a comprehensive hospi-tal between January 2011 and December 2013, antimicrobial susceptibility testing results were analyzed. Results The main gram-negative bacilli isolated from wound specimens of orthopedic patients were Pseudomonas aeruginosa (P .aeruginosa)(16.72%),Escherichia coli (E.coli)(15.40%),and Enterobacter cloacae (E.cloa-cae)(12.76%).The detection rates of extended-spectrum beta-lactamase-producing E.coli and Klebsialla pneu-moniae (K .pneumoniae)were 54.29%(57/105)and 31 .43% (22/70)respectively,and mainly distributed in the trauma orthopedic department,accounting for 49.12% and 45.45% respectively.The susceptibility rates of E.coli, K .pneumoniae ,and E.cloacae to meropenem and imipenem were all 100.00%.The susceptibility rates of E.coli and K .pneumoniae to amikacin,piperacillin-tazobactam and amoxicillin/clavulanic acid were all >80%.Suscepti-bility rate of E.cloacae to most antimicrobial agents were 71 .26% -100.00% except for piperacillin(64.37%). Susceptibility rates of P .aeruginosa to most antimicrobial agents were >85% except for cefepime (78.95%)and aztreonam (65.79%).Conclusion Gram-negative bacilli are the most common pathogens in wound infection of or-thopedics patients.In order to use antimicrobial agents rationally and improve clinical treatment effect,it is impor-tant to realize the distribution of pathogens and antimicrobial resistance.

Objective To explore the intervention effect of evidence-based nursing on the health behavior of elderly hypertensive patients in the community.Methods 187 elderly hypertensive patients who were hospitalized in December 2015 and met the inclusive criteria were divided into observation group (n=93) and control group (n=94).The observation group received evidence-based nursing according to the evidence-based medical system evaluation while the control group was given regular nursing both for 6 months.The clinical efficacy of two nursing modes was observed and the differences between pre-intervention and pose-intervention and groups were recorded and analyzed with a self-designed questionnaire, drug compliance questionnaire and health behavior scale.Results In the observation group, the blood pressure was effectively controlled or reduced, treatment compliance was significantly increased and body mass index (BMI) was within the ideal range 6 months later.Scores of unhealthy behaviors such as those in living habits and mental stress were lower than those in the control group, which showed significant difference (P<0.05).There was no significant difference in activity participation between the two groups (P>0.05).Conclusion Evidence-based nursing intervention can effectively control the hypertension, improve the treatment compliance of the community elderly hypertension patients and help lead them to a more positive and healthier life style.

Objective To investigate the relation between the apotosis of B cells in the peripheral blood (PB) and the expression of interleukin (IL)-17 in patients with rheumatoid arthritis (RA).Methods The proportions of apoptosis of B cells in the PB of 80 patients with RA and 80 healthy controls were measured by flow cytometry.B cells in the PB of 20 RA and 20 healthy individuals were isolated by MACS and Western blotting was used to detect the Bcl-2 and Caspase-3 protein levels.IL-17 levels were detected by enzyme-linked immunosorbent assay (ELISA).T-test and linear regression were used to analyze the data.Results The proportions of apoptosis of B cells in the PB of patients with RA and healthy controls were (14±6)％ and (24±9)％ respectively.The rate of apoptosis of B cells in patients with RA was significantly less than healthy controls (t=2.737,P=0.021).The Bcl-2 protein level of B cells in the PB of patients with RA group was significantly higher than that of control group (26±10,12±6,P＜0.01).Conversely,the Caspase-3 protein level of B cells in the PB of patients with RA group was significantly lower than that of the control group (16±7,31±12,P＜0.01).ELISA detected elevated level of serum IL-17 in the patients with RA as compared with controls [(69±19),(27±10) pg/ml,t=4.631,P=0.014].There was a negative correlation between the level of IL-17 and apoptosis of B cells in patients with RA (r=0.36,P＜0.01).Conclusion The elevated bcl-2 and reduced caspase-3 of B cells in patients with RA further proves there is abnormal apoptosis of B cells in RA patients.There is negative correlation between the expression of IL-17 and apoptosis of B cells in patients with RA and IL-17 can inhibit B cell apoptosis.
