Objective:To analyze the analgesic method and analgesic use for postoperative patients in our hospital. Method:100 cases with postoperative pain in the general surgery department,orthopedic department and gynecological department were chosen from March to June in 2009.Their analgesic method,analgesic use,visual analog scale(VAS) scores and adverse drug reaction were analyzed.Result:The rate of patient-controlled analgesia(PCA) use was 25.0%. The cases who used opioid and non-steroidal anti-inflammatory drugs(NSAIDs) in 3 days after operations were 20 and 44, respectively.The rate of the drug combination was low.Pethidineand diclofenac potassium were major drugs to relieve their postoperative pain.VAS score in 1 day post-operation was 3.43.Conclusion:The use of analgesics was positive in our hospital, but the insufficient analgesia and little drug combination existed,and drug selection is also limited.

An investigation on pathogens was performed on 219 consecutive adult inpatients with community-acquired pneumonia (CAP) from November 2008 to August 2009 in Hebei Province.Sputum samples from all patients in acute phase were collected for multiplex polymerase chain reaction (PCR) detection. Pathogens were identified in 125 patients. Streptococcus pneumoniae was the most common pathogen isolated in 75 cases (60％) ; influenza A virus was the most common virus isolated in 32 cases (26％) ; and mixed infection were found in 31 patients (25％). Streptococcus pneumoniae species were more frequent among patients aged ≤30 and 51 -70; Haemophilus influenzae species were more frequent among patients with coexisting disease; the percent of Mycoplasma pneumoniae species infections in the lowrisk groups( Ⅰ - Ⅱ ) was higher than patients in the high-risk groups ( Ⅲ - V ).The percent of virus pneumoniae species infections in patients with coexisting disease trended to higher than patients without coexisting disease,but the difference was not statistically significant ( P ＞ 0.05 ).The results indicate that Streptococcus pneumoniae remains the major bacteria,Viruses are frequently detected in CAP with influenza A virus being the most common one; and mixed infection should not be ignored.The age and underlying diseases are important factors influencing the distribution of pathogens.

Objective To analyze the changes of leptin and adiponectin levels in serum of patients with diabetic retinopathy and investigate their chnical significance in diabetic retinopathy (DR).Methods One hundred and twenty-one patients with type 2 diabetes mellitus as the case group who hospitalized from Nov.2012 to Nov.2013.Among the patients,41 cases of non-DR,40 cases of nonproliferative-DR,40 cases of proliferativeDR.Forty healthy were served as the control group.The levels of leptin and adiponectin in serum were detected by Enzyme-Linked Immuno Sorbent Assay (ELISA).Results The overall levels of leptin in case group was (15.25 ± 4.70) μg/L,significantly higher than the control group ((6.15 ± 1.70) μg/L; t =-11.696,P ＜0.01)).The level of adiponectin in case group was (7.39 ± 1.92) mg/L,lower than the control group ((11.10 ± 1.46) mg/L; t =11.216,P ＜ 0.01).Moreover,the levels of leptin increased successively from (10.91 ±1.21) μg/L in NDR,(15.22 ±3.75) μg/ L in NPDR and (20.50 ±3.70) μg/L in PDR.While,the adiponectin levels decreased from (9.61 ± 1.35) mg/L in NDR,(7.11 ± 1.18) mg/L in NPDR and (5.34 ± 1.36) mg/L in PDR respectively.And the differences between the groups were significant(F =149,542,291,550;P ＜0.05).The levels of leptin and adiponectin in serum showed a negative correlation (r =-0.662,P ＜0.01).Condusion Levels of leptin and adiponectin in serum associate with DR,and both of them might be the important indexes for the prediction and curative effect evaluation of DR.

Objective:To test the validity and reliability of the Chinese version of the Br?set Violence Check-list (BVC-C).Methods:With the authorizing permission by the author,the BVC was translated into Chinese and a-dapted,and five psychiatry experts who had worked more than 20 years were invited (3 clinical doctors and 2 nur-ses)to evaluate the content validity of the scale as the content validity index.Totally 556 inpatients who met the di-agnosis criteria for mental disorders according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10)were totally selected to proceed the formal testing.The BVC scale was used to evaluate inpatients every 8 hours,the Modified Overt Aggression Scale (MOAS)was used to test concurrent validity;the results of the real attacking incidents were used to test the criterion validity;the internal consistency re-liability of the scale was tested by Cronbach αcoefficient.Results:The content validity index of the scale was0.93.In addition to the own attack subscale,the MOAS total scores and the other 3 subscales scores were positively correlated with the BVC total scores and each item score (r =0.11 -0.69,P <0.01).The best criterion validity was 8 hours through analyzed,the AUC was 0.98.When the cut-off was 2,the sensitivity and specificity were 78.9% and 95.1% respectively.The Cronbach αcoefficient was 0.76 and the item total correlations were 0.47 -0.80 (P <0.01).Conclusion:It suggests that the BVC-C has good validity and reliability,which could be used as an effective prediction tool for psychiatric violence risk assessment.

0.05).The concentration of IL-6 in sputum of multi-virus infection group(122.51?39.86)ng/L was higher than in single virus infection group(65.30?34.92)ng/L.The concentration of IL-6 in sputum of bacteria-virus mixed infection group(120.31?46.62)ng/L was higher than in bacteria or virus single infection group(83.61?47.83)ng/L.Conclusion Streptococcus pneumonia and influenza virus A infection are important factors in AECOPD at early stage.Virus infection would prolong recovery time,increase inflammation of the airway and even induce bacteria infection.Therefore,we should pay more attention to the virus infection in COPD patients,especially A-type influenza virus.

Objective To compare the preparation efficiency of mouse pox and mouse hepatitis antibodies between two substrains of BALB/c and Big-BALB/c (B-BALB/c) mice, and to provide a theoretical basis and reference for the selection of laboratory animals in the preparation of monoclonal antibodies inducedin vivo through hybridoma.Methods Individuals weighing more than 5% of the weight of normal animals at 4 weeks of age (the criterion for late selection is more than 10%) were selected from a population of conventionally bred BALB/c mice and bred individually, and a subline of B-BALB/c mice was prepared after 10 generations of selection. A total of 40 BALB/c mice and 40 B-BALB/c mice aged 10 to 11 weeks, half male and half female, were selected and inoculated with the mousepox monoclonal antibody hybridoma cell line G23 or the murine hepatitis monoclonal antibody hybridoma cell line Y15 pre-treated with liquid paraffin, respectively. Mice ascites containing monoclonal antibodies were obtained by in vivo induction. The antibody titer was tested by indirect ELISA. The mice were grouped based on the sub-strains, gender and inoculation type of hybridoma to analyze the ascites production, antibody titer and antibody production, and to evaluate the antibody preparation efficiency of the two BALB/c mouse sub-strains.ResultsAfter 10 generations of breeding, the body weight of 10-week-old male and female B-BALB/c mice increased by 22.3% and 12.8%, respectively, compared with BALB/c mice of the same age. Compared with BALB/c mice, B-BALB/c mice had better tolerance and adaptation to secondary ascites collection. Compared with BALB/c mice, the ascites production and antibody titer during the preparation of antibodies in B-BALB/c mice were significantly increased, especially in the hybridoma cell line G23 vaccination group (both P＜0.000 1) . After inoculation with the hybridoma cell lines G23 or Y15, the average antibody production of B-BALB/c mice (14.99×10⁴ U and 33.22×10⁴ U) was higher than that of BALB/c mice (5.33×10⁴ U and 19.31×10⁴ U) (both P＜0.01). After inoculation with hybridoma cell line G23, the average antibody production per unit body weight of B-BALB/c mice (0.55×10⁴ U/g) was higher than that of BALB/c mice (0.23×10⁴ U/g) (P＜0.000 1). And the antibody production per unit body weight of female B-BALB/c or BALB/c mice was higher than that of male B-BALB/c or BALB/c mice (bothP＜0.01).Conclusion B-BALB/c mice can be used as an alternative to BALB/c mice in the in vivo induction of monoclonal antibody preparation, which can achieve the purpose of reducing the number of experimental animals used, lowering the labor cost, and improving the efficiency of antibody preparation.
