OBJECTIVE To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study. METHODS Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose. RESULTS The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed. CONCLUSION The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.

Objective:To explore the influencing factors of the long-term quality of life(QOL).Methods:According to the standard of diagnosis of primary lung cancer, a total of 74 patients with primary lung cancer were included in the study, who were first diagnosed by pathology and /or cytology and /or clinic from 1 January 2010 to 30 June 2016 in Tangshan Third Hospital, Heibei Province, and whose data were analyzed retrospectively.The Chinese version of FACT-L (4.0) QOL questionnaire was used to evaluate the QOL in 74 patients with primary lung cancer who survived more than three years.Multivariate regression statistical method was used to analyze the main influencing factors.Results:All patients with long-term survival lung cancer were treated by operation, their average QOL score was ( 126.62±13.29). Age, type of medical insurance and clinical stage had significant influence on QOL ( P<0.05). There was no significant difference in the total QOL scores between<50-year-old group(138.18±13.92) and ≥50-<60-year-old group(138.18±13.92, 137.04±12.82)(all P>0.05), but they were higher than that in ≥60-year-old group (115.28 ±13.11) (all P<0.05). The QOL of residents′ medical insurance patients (117.92 ±13.13) was lower than that of employees′ medical insurance patients (142.69±13.07) ( t=10.849, P=0.002). The QOL scores of stage Ⅰ and Ⅱ (140.34 ±12.88, 133.31±12.07) had no significant difference, but which were higher than that of stage III (96.84 ±13.46) ( P<0.05). Conclusion:Patients with long-term survival lung cancer after surgery could maintain a better QOL by early detection, timely surgery and constantly improving the medical security system to reduce the financial burden of patients.

Cylindromatosis gene is a kind of tumor suppressor genes, whose mutation or deletion will lead to the development of a cylindrical tumor. The deubiquitinating enzyme CYLD protein encoded by it is a member of the deubiquitinating enzyme family. CYLD alters the function of the target molecules by removing the ubiquitin chain linked to the substrate protein K63, and participates in the regulation of signaling pathways, such as NF-κB, JNK and Wnt. This article reviews the recent year’s research progress of CYLD, especially its negative regulatory role in the progression of liver-related diseases.

Objective To explore the clinical efficacy and safety of blind insertion of bronchial occluder for children with one-lung ventilation under the guidance of tracheal catheter obliquely facing right or left. Methods A total of 70 children undergoing right thoracotomy in our hospital were selected as study subjects, and were randomly divided into observation group (trachea tube inclined to right) and control group (trachea tube inclined to left), with 35 cases in each group. The baseline data and related clinical indexes, and the incidence of postoperative complications were compared between the two groups. Results There was no significant difference in baseline data between the two groups (P＞ 0. 05). The blocking time in the observation group was significantly shorter, the rate of one-time success rate was higher, and the incidences of airway edema and hypoxemia after operation were significantly lower than that in the control group (P ＜ 0. 05). Conclusion The adjustment of the opening slope of the tracheal catheter to the right can effectively shorten the total timeconsuming of plugging, improve the one-time insertion success rate, and reduce the incidence of postoperative complications.

Objective To evaluate the efficacy of Arndt endobronchial blocker (AEB) for airway management during one-lung ventilation (OLV) in pediatric patients.Methods Thirty pediatric patients,aged 4 months-12 yr,weighing 5.6-26.0 kg,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,scheduled for elective thoracotomy under OLV requiring the use of single lumen tracheal tube assisted by AEB,were enrolled in this study.OLV was performed with the AEB placed outside the single lumen tracheal tube in pediatric patients below 2 years old and with AEB inserted through the single lumen tracheal tube in pediatric patients ≥ 2 years old.The rate of successful establishment of artificial airway at first attempt,time of establishing artificial airway,time of pulmonary collapse,AEB malpositions and airway pressure before and after OLV were recorded,and the efficacy of lung collapse was evaluated.Results The rate of successful tracheal intubation of extraluminal and endoluminal AEB placement at first attempt was 100％ in 30 pediatric patients,and no high airway pressure was found after OLV.The efficacy of lung collapse was poor in one patient and good in one patient,and intraoperative AEB malpositions were found in two patients among the pediatric patients used extraluminal AEB placement.The efficacy of lung collapse was good in one patient,intraoperative AEB malposition was found in one patient,and SpO2 was decreased after OLV in one patient among the pediatric patients used endoluminal AEB placement.Conclusion Reasonably selecting the method of placing AEB followed by enhancing intraoperative airway management can be safely and effectively applied for OLV in pediatric patients.

Objective To evaluate GIPR protein expression in predicting prognosis of appendical neuroendocrine tumors (A-NET) patients.Methods The clinical data of 40 A-NET cases surgically treated from June 2007 to June 2017 at Tianjin Police Hospital were analyzed.The expression of GIPR markers was detected by immunohistochemistry (IHC).Results There were 25 male and 15 female patients,with an median age of 59 years.Sex,tumor site,tumor size,tumor stage and lymph node metastasis were not related to prognosis (P ＞ 0.05).The expression of GIPR was positive in 18 cases and negative in 22 cases.There were 16 cases in G1 stage,20 cases in G2,4 cases in G3.The expression of GIPR protein and pathological grades were related to prognosis (P ＜ 0.05).Conclusions Symptoms of appendix neuroendocrine tumor are nonspecific.Diagnosis is dependent on pathological examination and immunohistochemistry.Positive GIPR protein expression predicts poor prognosis for A-NETs patients.

Objective To analyze the changes of serum markers of liver function and liver fibrosis in patients with fatty liver,and to explore the relationship between them,so as to provide scientific basis for the prevention and treatment of fatty liver into hepatic fibrosis. Methods From January 1st,2015 to December 31st, 2015,one thousand three hundred and forty-six healthy cases were selected,and 361 cases of fatty liver were diagnosed by ultrasound. Liver function index of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was detected by automatic biochemical analyzer. Hyaluronic acid (HA),laminin (LN),serum type Ⅲprocollagen peptide ( PC Ⅲ) and type Ⅳ collagen ( C-Ⅳ) were detected by enzyme-linked immunosorbent assay. The correlation between liver function and serum liver fibrosis indexes was analyzed by Pearson parameter analysis. Results The liver function index ALT,AST((69. 04±18. 72) U/L,(59. 78±15. 65)U/L) in fatty liver group were higher than those in the non-fatty liver group((25. 71±10. 25) U/L,(23. 68±8. 23) U/L),the differences were statistically significant ( t＝279. 283,388. 461,P＜0. 05) . Four serum fibrosis index HA,LN, PCⅢ,C-Ⅳ in the fatty liver group were (112. 64±21. 63) μg/L,(125. 85±27. 52) μg/L,(127. 28±29. 37) μg/L,(79. 38±18. 52) μg/L,respectively,which were higher than those in the non-fatty liver group ( (53. 98 ±16. 84) μg/L,(86. 31±20. 46) μg/L,(53. 31±18. 23) μg/L,(57. 26±15. 86 ) μg/L),the differences were statistically significant ( t＝727. 724,170. 432,941. 357,71. 169,P＜0. 001) . The correlation analysis of liver function and serum liver fibrosis indexes showed that ALT and AST were positively correlated with the fibrosis indexes HA,LN,PCⅢ( correlation coefficient r＝0. 230,0. 119,0. 370;0. 363,0. 361,0. 509,P＜0. 001),and which had no significant correlation with C-Ⅳ(P＞0. 05). Conclusion Liver function and serum liver fibrosis index can be used as the important basis for monitoring and diagnosis on the progression of fatty liver disease.
