Thirty-three of 38 laboratories recommended by 18 countries and economies sent their results back. Twenty-four laboratories' results were observed as satisfactory. Five laboratories were identified as having reported at least one questionable result. Four laboratories were identified as having reported at least one unsatisfactory result.

Objective:To evaluate the clinical value of percutaneous transhepatic cholangial drainage (PTCD) and percutaneous transhepatic cholangial stent(PTCS)implantation therapy for malignant biliary obstruction in the elderly patients.Methods:Fifty three patients over 60 years-old were treated with PTCS implantation (n=35),PTCD for internal-external drainage(n=11),or single external drainage(n=7). The imaging examination was performed for all the patients one week after surgery. The serum levels of total bilirubin (TBIL) and alanine aminotransferase (ALT) were detected before and after surgery.Rusults:Metallic stents were successfully implanted in 32 patients during the surgery, and 3 patients were implanted 5 to 7 days later after PTCS. Both total serum levels of TBIL and ALT were significantly decreased at one week after surgery (P<0.05). The mean survival periods were 11.5 months for stent implantation patients and 5.5 months for PTCD patients. Conclusion:PTCD and PTCS are easy to perform and safe and effective in the treatment of malignant biliary obstruction of elderly patients.

Objective By exploring the relationship between the gene polymorphism of tumor related gene CD44 and the occurrence of breast cancer,the pathogenic gene or genetic predisposing gene of breast cancer was studied so as to provide theoretical basis and technical support for the screening,diagnosis and treatment of breast cancer.Methods Samples from 265 cases of breast cancer and 290 healthy female were collected. Multiple polymerase chain reaction (PCR) amplification and two generation sequencing were used to analyze the genetic polymorphism of 4 loci of CD44 rs11607862,rs13347,rs7116432 and rs8193.T he size and metasta-sis of 235 patients were compared.Results There was no significant difference in the expression of four sitesloci in breast cancer patients.However,in the analysis of cancer patients,the GG genotype of rs13347 lo-cus was lower than that of CC/CG type,and the lymph node metastasis rate was lower.Conclusion There is a certain correlation between the rs13347 loci of CD44 and the metastasis of breast cancer.The correlation be-tween the genetic polymorphisms of 3 loci of rs11607862,rs7116432 and rs8193 and the development of breast cancer needs more clinical samples and further research.

Objective? To investigate the correlation between self-efficacy, discharge readiness and self-management in readmitted patients with myocardial infarction, to explore the influencing factors to self-management and to provide a basis for intervention strategies in clinical practice. Methods? Totally 198 readmitted patients with myocardial infarction from First Hospital of Shanxi Medical University were selected using convenient sampling from December 2017 to May 2018 and investigated with the general informational questionnaire, Coronary Heart Disease Self-Efficacy Questionnaire (CHDSEQ), Discharge Readiness Scale (DRS), and Coronary Heart Disease Self-Management Scale (CHDSMS). Pearson correlation analysis and multivariate linear multilayer regression analysis were used to explore the influencing factors to self-management behavior. Results? The CHDSMS score of the 198 patients was (75.21±9.31), with a 63.12% scoring metrics;the CHDSEQ score was (50.91±10.43); the DRS score was (161.53±26.76). Correlation analysis showed that self-efficacy was positively correlated with self-management (r=0.537, P＜0.01), and that discharge readiness was positively correlated with self-management (r=0.416, P＜ 0.01). Multilayer correlation analysis revealed that the two factors could account for 14.1% of the variance of self-management. Conclusions? Medical and nursing workers should evaluate the discharge readiness of readmitted patients with myocardial infarction accurately, improve patients' self-efficacy, and provide effective discharge guidance for different groups according to relevant influencing factors, thus improving patients' self-management.

Hypertriglyceridemia-associated acute pancreatitis is an inflammatory disorder of exocrine pancreas caused by metabolism disturbances of triglyceride-rich lipoproteins.Currently,hypertriglyceridemia-associated acute pancreatitis is characterized by an escalating incidence rate,a tendency for more severe cases,and a lack of therapeutic drugs.Traditional Chinese medicine has distinct advantages in treating this disease,but its theoretical framework has not yet been established.Hypertriglyceridemia-associated acute pancreatitis manifests itself as a febrile disease,aberrant accumulation of fat and turbidity may stem from dietary imbalances and visceral dysfunction in ordinary individuals.The prolonged accumulation of fat and turbidity can transform into turbid pathogen,subsequently engendering heat,constituting a pivotal pathogenic factor.Throughout the progression of the disease,the fiery pathogen consumes the fat and turbidity,resulting in the generation of toxic heat,which is a crucial mechanism in the exacerbation of the disease severity.Thus,this article posits therapeutic principles aimed at averting the transformation of fat and turbidity into turbid pathogen and counteracting toxic heat in this disease.This article reviews two key theories from traditional Chinese medicine classics relevant to hypertriglyceridemia-associated acute pancreatitis:the theory of fat-turbidity associated with hypertriglyceridemia and the febrile disease related to acute pancreatitis.Combining these traditional theories with modern research on the mechanisms that intensify hypertriglyceridemia-associated acute pancreatitis and the corresponding targets of traditional Chinese medicine,it suggests that the pathogenesis of"fat-turbidity-toxic heat"serves as the theoretical basis of traditional Chinese medicine for the aggravated severity of hypertriglyceridemia-associated acute pancreatitis.The article aims to offer new insights for the treatment of hypertriglyceridemia-associated acute pancreatitis.
