Objective To investigate the correlation between serum total bile acid level and coronary atherosclerosis. Methods The clinical data of 1408 patients who had underwent coronary angiography were retrospectively analyzed. The patients were divided into coronary atherosclerosis group (stenosis ≥ 50%, 681 cases) and coronary normal group (stenosis < 50%, 727 cases) according to the results of coronary angiography. The general clinical data, serum total bile acid, serum creatinine, fasting plasma glucose, low-density lipoprotein cholesterol (LDL-C) and so on were compared between 2 groups, and the indexes analyzed by Spearman correlation analysis and multivariate Logistic regression analysis. Results There were no significant differences between 2 groups in the sex constitution, the family history of hyperlipidemia and the history of lipid-lowering therapy (P>0.05). The rate of smoking, rate of hypertension, rate of diabetes, age, body mass index (BMI), creatinine, fasting plasma glucose, total bile acid and low density lipoprotein cholesterol in coronary atherosclerosis group were significantly higher than those in coronary normal group:18.6%(127/681) vs. 14.2%(103/727), 64.6%(440/681) vs. 45.8%(333/727), 48.5%(330/681) vs. 22.7%(165/727), (58.9 ± 12.2) years vs. (56.7 ± 13.1) years, (25.6 ± 4.3) kg/m2 vs. (24.9 ± 4.5) kg/m2, (70.28 ± 15.94)μmol/L vs. (52.79 ± 12.75)μmol/L, (6.82 ± 2.73) mmol/L vs. (5.57 ± 2.35) mmol/L, (7.86 ± 4.38)μmol/L vs. (5.63 ± 3.71)μmol/L and (3.32 ± 0.69) mmol/L vs. (2.28 ± 0.57) mmol/L, and there were statistical differences (P<0.05 or <0.01). The Spearman correlation analysis result showed that coronary atherosclerosis was positively correlated with men, age, diabetes, hypertension, BMI, serum creatinine and total bile acid (r=0.084, 0.068, 0.322, 0.263, 0.073, 0.248 and 0.176; P < 0.05 or < 0.01). The multivariate Logistic regression analysis result showed that men, diabetes, hypertension, serum creatinine, BMI ( >24 kg/m2) and total bile acid levels were risk factors of coronary atherosclerosis (P<0.05 or<0.01). Conclusions The serum total bile acid level is positively correlated with the severity of coronary atherosclerosis, which may be one of the independent risk factors for coronary atherosclerosis.

Objectives To establish method for collecting haemocytes of Oncomelania hupensis and study its morphology and immunological importance. Methods Referring to the method of haemocytes collection from peripheral lymphoid organ, suspension technique was used for collection of haemocytes from snails, which were then Giemsa-stained and observed under microscope. Stained by gentian violet, number of haemocytes was counted and compared with that of conventional squashing method and needling method by ANOVA and Dunnett-t test. Supernatant from freeze thawing haemocytes was applied for the tests of immuno-precipitation, bacteriostasis, and phagocytosis. SDS-PAGE was used to analyze relative molecular mass of protein ingredients. Results Four kinds of haemocytes were found: round cells with filiform filopodia, acidophilic and basophilic round cells both without filiform filopodia, and spindle cells. The average diameter of the 4 type cells was 10.93, 6.13, 6.08, and 11:06?m, and occupied 50%, 30%, 5%, and 15% respectively. The mean of haemocytes received from suspension, squashing and needling methods was 15 000, 6 600 and 300/ml respectively. ANOVA analysis showed F=281.47, P

Objective To investigate the value of muhiple inflammatory cells and clinical score in early diagnosis and prognosis assessment of trauma sepsis risks.Methods This retrospective control study enrolled 209 severe trauma patients admitted from January 2010 and May 2016.White blood cell count,lymphocyte count and percentage,monocyte count and percentage,neutrophil count and percentage,ratio of neutrophil to lymphocyte count (N/L),acute physiology and chronic health evaluation (APACHE) Ⅱ score,sequential organ failure assessment (SOFA),improved early warning score (MEWS),Glasgow coma score (GCS),multiple organ dysfunction syndrome (MODS) score and lactic acid (LAC) were collected on the day of admission and 3,5,7 days after trauma.These data were applied to construct weighted and biological score models for early diagnosis and prognosis of traumatic sepsis.Receiver operating characteristic curve (ROC) was performed and area under the curve (AUC) was calculated to measure the value of the two models in early diagnosis and prognosis of sepsis.Results AUC of the weighted model combined by APACHE Ⅱ score,SOFA score and MEWS was 0.729 on the day of admission.AUC of the weighted model combined by inflammatory cells was 0.680 and AUC of the biological score model was 0.800 3 days after trauma (P ＜ 0.05).AUC of the weighted models combined by inflammatory cells was 0.798 and AUC of the biological score model was 0.812 5 days after trauma (P ＜ 0.05).AUC of the weighted models combined by inflammatory cells was 0.706 and AUC of the biological score model was 0.713 7 days after trauma (P ＞ 0.05).AUC of the biological score model had significant difference 3 days and 5 days after trauma (P ＜ 0.05).Of the weighted model combined by APACHE Ⅱ score,MODS score,GCS and LAC to evaluate the prognosis of sepsis,the AUC showed significant difference on the day of admission (0.838),3 days after trauma (0.878),5 days after trauma (0.947) and 7 days after trauma (0.936) (P ＜ 0.05).Conclusions Biological score possesses better effect on early diagnosis of sepsis 3 days after trauma.Weighted model combined by APACHE Ⅱ score,MODS score,GCS and LAC can effectively predict the prognosis of sepsis 5 days after trauma.

OBJECTIVE: To evaluate the efficacy and safety of thread-dragging through fistula method in treating patients with simple anorectal fistula. METHODS: In this multi-centered, prospective, and randomized controlled clinical trial, 244 patients with simple low or high anorectal fistula were randomly divided into study group (with the method of thread-dragging through fistula) and control group (with the method of incision or thread-drawing). The healing time and curative rate of anorectal fistula, and the integral calculus of clinical symptom and life quality evaluations before and after treatment were all examined. The maximal anal canal squeeze pressure was measured to compare the therapeutic safety between these two groups. The health economical benefits were also assessed to determine which therapeutic method was more economical. RESULTS: The curative rate of simple low and high anorectal fistula were of no significant differences between the study group and the control group. The healing time of simple low anorectal fistula in the study group and the control group were (22.26+/-8.67) d and (31.41+/-11.39) d respectively, while the healing time of simple high anorectal fistula in the study group and the control group were (24.73+/-8.15) d and (32.20+/-12.60) d respectively, and there revealed significant differences between these two groups. Each integral calculus of clinical symptom evaluation in the study group was not obviously different from those in the control group besides the integral calculus of anal sphincter function. The integral calculus of life quality between the study group and the control group of simple low anorectal fistula had no significant differences. The integral calculus of anal sphincter function and confidence in treatment in the study group of high anorectal fistula were better than those in the control group. The hospitalization expense of the study group was remarkably lower than that of the control group. The maximal anal canal squeeze pressure in the study group after treatment was not reduced obviously as compared with that in the same group before treatment, while it was decreased significantly in the control group after treatment as compared with those in the same group before treatment and in the study group after treatment. CONCLUSION: The method of thread-dragging through fistula in treating simple low and high anorectal fistula can shorten the course of the disease, save the hospitalization expenses, improve the life quality of the patients, and protect the anal sphincter function.

The present study evaluated the effect of non-thermal plasma on skin wound healing in BalB/c mice. Two 6-mm wounds along the both sides of the spine were created on the back of each mouse (n=80) by using a punch biopsy. The mice were assigned randomly into two groups, with 40 animals in each group: a non-thermal plasma group in which the mice were treated with the non-thermal plasma; a control group in which the mice were left to heal naturally. Wound healing was evaluated on postoperative days (POD) 4, 7, 10 and 14 (n=5 per group in each POD) by percentage of wound closure. The mice was euthanized on POD 1, 4, 7, 10, 14, 21, 28 and 35 (n=1 in each POD). The wounds were removed, routinely fixed, paraffin-embedded, sectioned and HE-stained. A modified scoring system was used to evaluate the wounds. The results showed that acute inflammation peaked on POD 4 in non-thermal plasma group, earlier than in control group in which acute inflammation reached a peak on POD 7, and the acute inflammation scores were much lower in non-thermal group than in control group on POD 7 (P<0.05). The amount of granular tissue was greater on POD 4 and 7 in non-thermal group than in control group (P<0.05). The re-epithelialization score and the neovasularization score were increased significantly in non-thermal group when compared with control group on POD 7 and 10 (P<0.05 for all). The count of bacterial colonies was 10(3) CFU/mL on POD 4 and <20 CFU/mL on POD 7, significantly lower than that in control group (10(9) CFU/mL on POD 4 and >10(12) CFU/mL on the POD 7) (P<0.05). It was suggested that the non-thermal plasma facilitates the wound healing by suppressing bacterial colonization.
