Objective To explore the causes of the misdiagnosis of spontaneous rupture of spleen.Methods 8 cases of spontaneous rupture of spleen during 1986～1998 were reviewed retrospectively.Results 5 cases were misdiagnosed, with the misdiagnosing rate of 62.5%.Conclusion For unknown upper bellyache accompanied with unexplainable loss of blood and with no history of trauma,the patients should be examined by B ultrasound or abdominal puncture should be peformed.If there is pathological process of liver and spleen such as schistosoma and hepatitis or the excessive functioning of spleen,the more attention should be paid to the occurrence of spontaneous rupture of spleen.Furthermore,the increase of the belly pressure caused by satiation or hard labour helps to diagnose such case.

There are multiple sophisticated approaches that can be used in estimations on health effects resulting from environmental pollution. By comparison, human capital approach and averted expenditure approach are not suitable to be the first choice because of the insufficient capability of capturing all aspects of health effects. Date availability and estimation extrapolation limit the application of hedonic wage approach and hedonic price approach. It has been accepted universally for the flexible technique provided by contingent valuation approach that any health effects can be separately evaluated depending on researchers' purposes. Based on the powerful macroeconomic theory, general equilibrium theory, the CGE model is powerful to simulate the mechanism of interaction between multi-sectors with a national economic system so as to objectively reflect the health impacts on national economy due to environmental pollution.

Objective:To investigate the expression of serum caspase-cleaved cytokeratin 18(CCCK-18) in patients with cerebral ischemic stroke and its diagnostic value.Methods:One hundred and six patients with cerebral ischemic stroke who were diagnosed and treated in Affiliated Dongfeng Hospital from October 2018 to October 2019 were selected as the study group. Ninety patients who underwent digital subtraction angiography (DSA) during the same period and showed no other abnormalities inside or outside the skull were selected as control group. The baseline data of gender, age, drinking history, smoking history, hypertension history, diabetes history, coronary heart disease, and other subjects in the two groups had no significant differences ( P>0.05). Cubital venous blood of 5 ml from two groups of subjects were collected, and the level of serum CCCK-18 was detected by enzyme-linked immunosorbent assay. The levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) were detected by enzymatic method. The receiver operating characteristic curve (ROC curve) was used to analyze the diagnostic efficacy of serum CCCK-18 in patients with ischemic stroke, and the relationship between serum CCCK-18 and TC, TG, LDL-C, HDL-C were analyzed by Pearson test. Results:The levels of serum CCCK-18, TC, TG, and LDL-C in the study group were significantly higher than those in the control group: (158.10 ± 50.89) U/L vs. (85.57 ± 35.25) U/L, (4.26 ± 0.92) mmol/L vs. (3.92 ± 0.80) mmol/L, (2.34 ± 0.53) mmol/L vs. (1.83 ± 0.47) mmol/L, (3.12 ± 0.73) mmol/L vs. (2.61 ± 0.67) mmol/L, and HDL-C level was lower than that in the control group: (1.20 ± 0.24) mmol/L vs. (1.32 ± 0.28) mmol/L, and there were significant differences ( P<0.05). Logistic regression analysis showed that CCCK-18, TC, TG, LDL-C, and HDL-C were independent risk factors for patients with ischemic stroke ( P<0.05). The area under the curve(AUC) of serum CCCK-18 to distinguish ischemic stroke from the control group was 0.878, with a sensitivity of 84.91% and a specificity of 78.89%. The AUC of serum CCCK-18 to identify patients with mild ischemic stroke was 0.763, with a sensitivity of 70.37% and a specificity of 78.89%. Correlation analysis showed that serum CCCK-18 was positively correlated with TC, TG, and LDL-C in patients with ischemic stroke ( r = 0.711, 0.722, 0.705), and negatively correlated with HDL-C ( r = - 0.714), and there were significant differences ( P<0.01). Conclusions:Serum CCCK-18 levels are significantly increased in patients with cerebral ischemic stroke, which can be used as a biomarker for diagnosis and judgment of disease severity.

Objective To survey the incidence of adverse reaction induced by traditional Chinese medicine injection and provide valuable suggestion for using traditional Chinese medicine injection.Methods Clinical data of 1860 patients who were under treatment of traditional Chinese medicine injection during January 2010 to December 2014 were studied to survey adverse reaction incidence, effected system-organs and risk factors of adverse reaction.Results Comparison of incidence adverse reaction of traditional Chinese medicine injection, Qingkailing injection adverse occurrence rate reached the highest 11.76% for all types, followed by Shenmai injection and Shuanghuanglian injection.Adverse reactions involving the organ and the performance was compared, adverse reactions mainly involved the organs for the skin and accessories, circulatory system, accounting for 56.15%, the incidence of adverse reactions of the rest of the organ system was less.Not determine the treatment based on differentiation of symptoms and signs, combined with injection, ultra treatment application and distribution of liquid static for a long time all differences were statistically significant ( P <0.05), leading to the main risk factors of the occurrence of adverse reactions.Conclusion Traditional Chinese medicine injections occurred and the incidence of adverse reactions was higher, wider range, organ involvement mainly skin and its appendages and circulatory system, not dialectical treatment and rational drug use is lead to adverse risk factors, actively preventment and timely treatment to reduce the incidence of adverse reactions.

Objective:To analyze and evaluate the effect after the PIVAS workflow optimization in our hospital. Methods: One-for-one grouping preparation was carried out by pharmacists and nurses. The checking of medicines, solvents and empty ampoules be-fore and after the preparation was performed by pharmacists, and the preparation of infusions was operated by nurses according to the operation specification. The preparation workload, error number in each link and damage of ampoules and finished goods before the op-timization and in 5 months after the optimization were compared. Results:The working efficiency was obviously improved with less time of about 0. 5 h for the same workload, the error rate was decreased by 40%, and the ampoule damage was reduced by 60% before and during the preparation. Conclusion:The PIVAS workflow optimization improves the working efficiency and management level.

Objective To optimize the formulation of self-microemulsifying drug delivery systems containing tanshinone ⅡA(tanshinone ⅡA-SMEDDS) and assess the quality of tanshinone ⅡA-SMEDDS. Methods Pseudoternary phase diagrams were used to choose the oil,emulsifier,co-emulsifier,and their proportion in the formulation on the basis of the ability to form emulsions and regions. Then the self-emulsifying time,droplet and morphology,size distribution,?-potential,stability,and other aspects of the quality were evaluated. Results The formulation of tanshinone ⅡA-SMEDDS was as follows:ethyl oleate-Labrasol-PEG 400=10%:45%:45%,drug loading ratio was 2.25 mg/g. The self-microemulsifying time of tanshinone ⅡA-SMEDDS in 0.1 mol/L hydrochloric acid solution was less than 1 min,the emulsion drops were spherical shape with average particle size of (84.9?2.1) nm and the average ?-potential (-24.0?1.15) mV (n=3). So tanshinone ⅡA-SMEDDS was stable. Conclusion In this paper,the tanshinone ⅡA-SMEDDS has a good self-emulsifying performance. It is expected to further stabilize the preparation of tanshinone ⅡA self-microemulsifying agents.
