Anti-medical violence legislation: international experience and inspirations for China / 中华医院管理杂志

Traditional mindset in anti-medical violence legislation tends to divert the responsibility to prevent medical violence to the party of the lowest costs, a design of obvious loopholes in reducing medical violence occurrence. By combining the legal liability and penalty adjustment to counter medical violence crimes, the US, Australia and South Korea are trying to match the private cost of victims and its social cost with the punishment of crime law. In this sense, China should highlight the nature of public safety of medical service, zero tolerance report and optimal punishment to medical violence crimes. This approach can take place of the existing incentive mechanism featuring violent conflicts, being conducive to building a safe and harmonious doctor-patient relationship.

An optimal penalty model of anti-medical violence legislation / 中华医院管理杂志

From the perspective of law-and-economics, this paper analyzed the characteristics between medical workplace and other workplace in terms of public safety liability, risk identifiability and preventability. Then it went on to explore the costs structure incurred by medical violence, namely personal costs of victims, public safety cost, risk prevention cost and service supply cost. A law-and-economics optimal penalty model is then developed based on the benchmark of crime of violence free of social cost, and by incorporating the social cost of medical violence. And it is found that an upward deflection of the crime cost curve sharply drives up the optimal penalty corresponding to various levels of violence, and lowers the threshold violence constituting criminal offence, thus balancing the social costs borne by the public for medical violence.

Clinical outcomes of peripheral blood stem cell transplantation for aggressive peripheral T-cell lymphoma / 中华血液学杂志

Objective@#To evaluate clinical outcomes of autologous and allogeneic peripheral blood stem cell transplantation (PBSCT) for aggressive peripheral T-cell lymphoma (PTCL).@*Methods@#From June 2007 to June 2017, clinical data of PTCL patients who underwent PBSCT were assessed retrospectively.@*Results@#Among 41 patients, 30 was male, 11 female, and median age was 38(13-57) years old. Seventeen patients with autologous PBSCT (auto-PBSCT) and 24 patients with allogeneic PBSCT (allo-PBSCT) were enrolled in this study. Eight patients (8/17, 47.1%) in auto-PBSCT group were ALK positive anaplastic large cell lymphoma (ALCL), 7 patients (7/24, 29.2%) with NK/T cell lymphoma and 9 patients (9/24, 37.5%) with PTCL-unspecified (PTCL-U) in allo-PBSCT group (P=0.035). There were 58.8% patients (10/17) in complete response (CR) status and 11.8% (2/17) in progression disease (PD) status before transplantation in auto-PBSCT group, and 8.3% (2/24) in CR status and 45.8% (11/24) in PD status before transplantation in allo-PBSCT group (P=0.026). The 2-years cumulative overall survival (OS) were (64.0±10.8)% and (53.5±9.7)% for auto-PBSCT and allo-PBSCT respectively (P=0.543). The 2-years cumulative disease-free survival (DFS) were (57.1±12.4)% and (53.5±10.6)% for auto-PBSCT and allo-PBSCT respectively (P=0.701). In patients with dead outcomes after PBSCT, 83.3% (5/6) of death cause was relapse in auto-PBSCT and 41.7% (5/12) of death cause was relapse in allo-PBSCT.@*Conclusion@#Both auto-PBSCT and allo-PBSCT were effective for PTCL.

Polycentric analysis of current situation of diagnosis of haemophilia in Chinese children / 中华实用儿科临床杂志

Objective To analyze the diagnostic status of haemophilia in Chinese children in recent years,and to provide information for increasing the life quality of children with haemophilia in China.Methods The pediatric haemophilia cases registration data were collected and analyzed by using questionnaire,from January 1,2008 to March 30,2014 in 13 haemophilia treatment centers of haemophilia treatment center collaboration network of China pediatric group.These centers were from 12 provinces / municipalities.Results A total of 554 cases were collected;median age was 7.0 years old(0.1 to 17.9 years old);among them,481 cases(86.8％) were hemophilia A,and 73 cases were hemophilia B (13.2％);55 mild cases (9.9％),290 moderate cases (52.4％),and 209 severe cases (37.7％);162 cases(29.2％) had family history,the other 392 cases(70.8％) had no family history.The diagnosis was made at a median age of 12.0 month-old(0 to 180.0 months);the diagnosis time was 0.5 months(0 to 144.0 months) after the first bleeding;diagnosis timing with short interval was in 356 cases(64.3％),long interval was in 198 cases(35.7％).The diagnostic timing was not correlated with disease severity (P =0.812) or the family history (P =0.243);but correlated with the severity of first bleeding(P =0.027) and per capita gross domestic product (P ＜ 0.01) in patients' residence.From 1996 to 2013,the annual number of newly diagnosed cases was increasing year by year,with a higher proportion of short interval of diagnose timing.Conclusions With development of hemophilia work in China,the number of diagnosis of haemophilia children is increasing year by year.Moderate and severe hemorrhage are both taken seriously and diagnosed timely.But the diagnosis is delayed in some children.Chinese haemophilia work still need to be strengthen and the propaganda and diagnostic technology are to be popularized.

Changes of liver fibrosis-related miRNAs induced by soluble egg antigen of Schistosoma japonicum / 中国血吸虫病防治杂志

Objective To investigate the expression of miRNA associated with hepatic fibrosis induced by Schistosoma ja-ponicum soluble egg antigen stimulation in mouse hepatocytes(AML12),so as to lay the foundation for clarifying the mecha-nism of schistosome infection leading to hepatic fibrosis. Methods The expressions of miR-122,miR-182,miR-23b,miR-27b and KSRP in AML12 cells treated with SEA were measured by q-PCR. KSRP protein in cell lyses was measured by Western blotting. AML12 cells were transfected with miR-27b precursor or anti-miR-27b for 24 h,then q-PCR was adopted to determine KSRP mRNA,and KSRP protein was detected by Western blotting. Results The expressions of miR-182,miR-23b and miR-27b were decreased and miR-122 was increased in AML12 cells following SEA treatment(all P<0.05). An increase of mRNA and protein of KSRP expression was also observed in AML12 cells after SEA stimulation(both P<0.05). In addition,KSRP mRNA expression was not changed significantly in AML12 cells transfected with anti-miR-27b or miR-27b precursor,and miR-27b precursor reduced KSRP protein expression as compared with the control. In contrast,the expression of KSRP protein was increased in the anti-miR-27b group and decreased in the miR-27b precursor group. Conclusions After the stimulation of SEA,the expressions of a variety of liver fibrosis-related miRNAs and KSRP change in murine hepatocytes,including miR-27b. And miR-27b can regulate the expression of KSRP. These findings might lay a foundation for further study on the molecular mechanism of fibrosis induced by schistosome infection.
