Objective To detect the protective mechanism of trehalose in tracheal cryopreservation.Methods Inbred male Sprague-Dawley (SD) rats were sacrificed with intraperitoneal injection of ketamine(150mg?kg -1).The tracheas were removed and immersed immediately in the freezing medium of low potassium dextran (LPD) solution only(Group Ⅰ) ,containing with 10% dimethylsulfoxide(DMSO)(Group Ⅱ), containing with 0.15mol?L -1 trehalose (Group Ⅲ),and containing with 10% DMSO and 0.15mol?L -1 trehalose (Group Ⅳ) respectively. A sterile plastic tube containing a 1-cm-long trachea was filled with the freezing medium,sealed,and frozen to -80℃ at rate of -1℃ per minute in a programmable freezer.Then the tube was stored in liquid nitrogen(-196℃) for 20 days. Then the specimen was thawed in a 37℃ water bath and rinsed with physiologic saline solution 10 times.Histologic changes before cryopreservation and after thawing were examined in each group. After the specimens were embedded in paraffin,5-(m-thick sections were stained with hematoxylin and eosin.The epithelium and cartilage was assessed. We also observed Bcl-2 and Bax gene expression by immunohistochemistry. At last, some tracheas(SD) after cryopreservation were thawed and transplanted into the abdominal cavity of Wistar rats. The transplanted tracheas were retrieved and assessed histologically.Results Microscopic findings of the tracheas in Group Ⅲ and Group Ⅳ showed their structure were intact and Bax gene expression was lower in cartilage after cryopreservation(20d) compared with other groups,especially in Group Ⅳ.The tracheas in Group Ⅲ and Group Ⅳ grew well after they were transplanted into cavity of Wistar rats heterotopically,too.There were no significant differences among 4 groups in Bcl-2 gene expression.Conclusion In tracheal cryopreservation the trehalose can protect the trachea by protecting the tracheal cartilage.It is one of the protective mechanism that the trehalose inhibit the Bax gene expression of cartilage cells.The concomitant use of trehalose and DMSO has a synergistic effect.

Objective:To study the application of HL-60 monocyte activation test in the pyrogen detection of vaccines. Methods:HL-60 cells were incubated with the standard pyrogen(endotoxin,zymosan and lipoteichoic acid)solution and the sample solution at different concentrations,and then IL-6 level was detected using ELISA kit. According to the concentration of standard pyrogen solution and the level of IL-6,the standard curve and linear relationship were obtained. Based on the IL-6 value from the sample solution,the pyrogen content of the sample was calculated. The standard pyrogen solution at middle concentration of the standard curve was used as the interference sample,and the interference assay was performed referring to the bacterial endotoxin test in Chinese pharmacopoeia. The pyrogen recovery rate and the content were detected using HL-60 / IL-6 assay in seven kinds of vaccines such as influenza vaccine(Split Virion),inactivated;hepatitis A(live)vaccine,freeze-dried;rabies vaccine(Vero Cell)for human use,freeze-dried;lyophilized human measles and rubella combined vaccine,live;measles and mumps combined vaccine, live; haemorrhagic fever with renal syndrome bivalent vaccine, inactived; group A and C meningococcal polysaccharide vaccine. Results:① The linear relationship between the pyrogen concentration and the IL-6 level was good,and R2 value was 0. 996,0. 993 and 0. 997,respectively. ② The recovery rate of pyrogen in the above vaccines ranged from 50% to 200% . ③ The endotoxin concentration of 10 batches of group A and C meningococcal polysaccharide vaccine was detected using HL-60 / IL-6 assay,and the average value of 6 batches from factory A was 134. 73 EU·ml-1 ,and that of 4 batches from factory B was 40. 75 EU·ml -1 . The pyrogen in the other vaccines was all negative. Conclusion:The HL-60 / IL-6 assay is suitable for the pyrogen detection of the seven kinds of vaccines.

Objective To explore the impacts of natural ovulation cycles and stimulation cycles on the outcome of intrauterine insemination (IUI) in order to improve the clinical effects of IUI. Methods 176 women received 384 stimulation cycles. According to different ovulation stimulation protocols , the women were divided into six groups including natural cycle (NC) group, clomiphene citrate (CC) group, letrozole (LE) group;human menopausal gonadotrophin (HMG ) group, CC + HMG group, and LE + HMG group. The pregnancy rate between nature cycles and ovarian hyperstimulation cycles was compared. Results The pregnancy rate was 9.33%in the nature cycle group and 13.27% in the stimulation cycle group, with a significant difference (P < 0.05);and it dif not differ significantly among the stimulation cycle groups (P > 0.05). Conclusions Use of ovulation-induction medications is one of the important factors affecting the pregnancy rate of intrauterine insemination. There are no differences in the outcome of IUI among different ovulation stimulation protocols.

ObjectiveTo investigate the pathological and biochemical features of each pathological subtype of bile duct injury type of drug-induced liver injury (DILI), and to verify the value and significance of pathological classification of DILI. MethodsA retrospective analysis was performed for the clinical data of 112 patients with bile duct injury type of DILI who were admitted to Shijiazhuang Fifth Hospital from January 2006 to January 2016 and China-Japan Friendship Hospital from October 2003 to June 2014. According to the pathological subtype, the patients were divided into mixed hepatitis group with 40 patients, cholestatic hepatitis group with 40 patients, and simple cholestasis group with 32 patients, and the three groups were compared in terms of types of drugs used, course of disease, R value, and peak values, changing trend, time to peak, and recovery time of liver biochemical indices. The independent-samples Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups. ResultsAmong the drugs inducing DILI, traditional Chinese medicine and Western medicine each accounted for half of the cases of bile duct injury type of DILI. Traditional Chinese medicine mainly included the drugs for osteoarthropathy, intervertebral disc bulge, alopecia, calculus-removing and cholagogic treatment, Yang-tonifying therapy, and skin diseases; 26 patients (65%) in the cholestatic hepatitis group had DILI caused by traditional Chinese medicine, while 16 patients (40%) in the mixed hepatitis group and 13 (40.6%) in the simple cholestasis group had such DILI. Antibiotics and antipyretic and analgesic drugs were the most common Western medicines for DILI. The mixed hepatitis group had the highest peak values of ALT and AST and R value, followed by the cholestatic hepatitis group and the simple hepatitis group (χ2=54.77, 44.21, and 5195, all P＜0.001), and there were no significant differences in the peak values of the other liver biochemical parameters between the three groups (all P＞0.05). In the mixed hepatitis group and the cholestatic hepatitis group, the time to peak of TBil was longer than that of ALT. There were no significant differences in course of disease, time to peak of liver biochemical parameters, and recovery time between the three groups (all P＞0.05). ConclusionEach subtype of bile duct injury type of DILI has unique clinical and biochemical features, and an understanding of such features may help to accurately judge clinical typing, pathological changes of targets, and degree of injury.
