Types of die-punch fracture of the distal radius based on three-column theory / 中华创伤骨科杂志

Objective To investigate the characteristics and types of die-punch fracture of the distal radius (DPFDR) based on three-column theory as well as its application value.Methods The imaging data of 560 cases of DPFDR were reviewed which had been treated at The Ninth People's Hospital of Wuxi from June 2007 to June 2017.They were 305 males and 255 females,aged from 13 to 95 years,with an average of 46.4 years.According to the three-column theory,the 560 DPFDR cases were divided into a single column group and a double column group.According to the fracture site and morphology,the former was further characterized as volar,dorsal,split and collapse types while the latter as metaphyseal,articular surface and mixed types.After being familiarized with our new classification,2 radiologists were asked to classify 100 cases of DPFDR independently.The inter-and intra-observer agreements were analyzed with Kappa statistics.Results There were 65 cases of single column DPFDR,including 3 ones of volar type,13 ones of dorsal type,14 ones of split type and 35 ones of collapse type;there were 495 cases of double column DPFDR,including 130 ones of metaphyseal type,155 ones of articular surface type and 210 ones of mixed type.The intra-observer Kappa coefficient was 0.877-0.937 and the intra-observer kappa was 0.916-0.959,showing high agreement.Conclusions Due to differences in violence nature and intensity,wrist position and bony quality of the patient at the time of injury,axial violent transmission may cause different types of die-punch fracture at the intermediate column of the distal radius and different types of mild radial column fractures as well.As our new classification may well characterize the site and morphology of DPFDR,it has high consistency to guide surgical treatment and prognosis judgment.

"Study on ""four-step"" teaching methods in traditional Chinese medicine course" / 中华医学教育探索杂志

Objective To evaluate the results of Four-Step methods in traditional Chinese medicine Course.Methods 40 five-academic-year clinical medical students and 40 seven-academicyear undergraduate students were randomized assigned into experimental group (n=40, 20 five-academicyear clinical medical students and 20 seven-academic-year students) and control group (n=40, 20 five-academic-year students and 20 seven-academic-year students).The control group received conventional teaching, while four-step teaching break the gap between Chinese medicine and western medicine, build the base, form the framework of Chinese medicine and extend knowledge was implemented in the experimental group.Through questionnaire score, group discussion, the final evaluation of the theory and clinical training evaluation, the learning of the experimental group students and the control group students was compared.SPSS 18.0 statistical software was used and t test was employed to make analysis of the relevant data.Results The questionnaire at the end of the semester showed that the average score of students in the experimental group (36.18 ± 0.96) was higher than that in the control group (26.62 ± 1.00), and the difference was statistically significant (P=0.017).In the discussion at the end of the semester, the experimental group paid more attention to the theory and technology of traditional Chinese medicine's learning persistence in future and its application in their professional practice.Scores in theory test were higher in seven-academic-year students in experimental group (88.40 ± 8.79) than in control group (82.15 ± 6.83) and the difference was statistically significant (P=0.017), but there was no difference in five-academic-year students between experimental group (75A0 ± 12.09) and control group (77.85 ± 11.99), which was not considered statistically significant different (P=0.524).In clinical practice, the rate of outstanding students in the experimental group of seven-academic-year was five percentage points higher than the control group, while the rate of outstanding students in the experimental group of five-academic-year was 10 percentage points higher than the control group.Conclusions Four step teaching is helpful to stimulating the learning enthusiasm of the students of traditional Chinese medicine, expanding students' vision of medical field, and promoting their construction of a more comprehensive medical knowledge framework.

Association between HLA-DRB1 allele polymorphism and susceptibility to chronic myelogenous leukemia in Chinese Han / 中国免疫学杂志

Objective: The aim was to explore the association between the HLA-DRB1 allele polymorphism and susceptibility to chronic myelogenous leukemia(CML)in Chinese Han population.Methods: The polymorphism of HLA-DRB1 alleles in 762 CML patients and 2 264 normal umbihcal cord blood samples were tested by polymerase chain reaction with sequence specific primer(PCR-SSP).Results: The most common allele in DRB1 locus in normal population was DRB1 * 15(17.25%), whereas DRB1 * 10 was the least frequent allele(1.39%).Compared with normal controls, the frequency of HLA-DRB1 * 08 was significantly increased in all CML groups(7.48%vs 5.39%, X~2 =8.963,OR= 1.023, P =0.004)and CML male groups(7.72%vs 5.39%,X~2 = 8.059,OR= 1.025,P = 0.007).But there was no significant difference between the normal controls and CML female patients.Conclusion: It should be concluded that DRB1 * 08 could be considered a susceptible allele for CML male patients.

Association of gene HLA-class I with leukemia / 中国实验血液学杂志

This study was aimed to investigate the corelation between the HLA (human leukocyte antigen) genes and susceptibility of leukeamia. 605 patients with leukeamia including 189 ALL, 184 AML and 232 CML were selected for this investigation. 900 normal umbilical cord blood samples from umbilical cord blood bank were used as control population compared to the leukemia patients. HLA-A, B, C typing was done by polymerase chain reaction with sequence-specific primers (SSP-PCR). The results showed that frequencies of HLA-A*26, A*68, B*56 in ALL patients were higher (4.46%, 2.65%, 1.17%), as compared with controls (2.31%, 0.95%, 0.22%), HLA-CW*06 in ALL patients was lower (3.64%), as compared with control (11.65%). In AML patients HLA-A*01 (9.41%), B*37 (3.60%) was higher and A*33 (3.60%), B*51 (4.73%) were lower than those in controls (3.57%, 1.75% and 7.64%, 7.93%). HLA-A*32, B*27, B*44, B*54, B*55 (2.18%, 3.96%, 5.06%, 4.63%, 2.84%) in CML patients were higher than those in control (0.84%, 2.04%, 3.07%, 2.44%, 1.29%). These results suggested that positive association may exist between certain HLA-class I genes and leukemias. These preliminary data may be useful for further study on the mechanisms of leukemia pathogenesis.

Analysis on the clinical diagnosis and treatment of pancreatic cystadenocarcinoma / 肿瘤研究与临床

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.
