Objective To investigate the expressions of Pokemon and c-myc in colorectal cancer,colorectal adenomas and normal colorectal mucosa tissues,and demonstrate its relationship with clinicopathological features and prognosis in patients with colorectal cancer.Methods The specimens were taken from colorectal cancer tissue of 86 patients,colorectal adenomas tissue of 60 patients,and 40 normal colorectal mucosa tissue.The expressions of Pokemon and c-myc protein were detected by immunohistochemistry,and the expressions of Pokemon and c-myc gene were detected by reverse transcription polymerase chain reaction (RT-PCR).The correlation between the expressions of Pokemon and c-myc,and clinicopathological features was analyzed.Results The positive expression rates of Pokemon and c-myc protein in colorectal cancer tissue were significantly higher than those in colorectal adenomas tissue and normal colorectal mucosa tissue:69.8％ (60/86) vs.13.3％ (8/60) and 5.0％ (2/40),73.3％ (63/86) vs.15.0％ (9/60) and 2.5％(1/40),and the expression levels of Pokemon and c-myc gene in colorectal cancer tissue were significantly higher than those in colorectal adenomas tissue and normal colorectal mucosa tissue:0.915 ±0.247 vs.0.358 ±0.102 and 0.277 ±0.085,1.272 ±0.360 vs.0.398 ± 0.153 and 0.255 ±0.097,there were statistical differences (P ＜ 0.05).The expression levels of Pokemon and c-myc gene in colorectal cancer tissue had a close correlation with the degree of infiltration,histological differentiation,lymph node metastasis,distant metastasis and Dukes stage,there were statistical differences (P ＜ 0.05),but had no correlation with the sex,age,and tumor diameter (P ＞ 0.05).Conclusions The expression levels of Pokemon and c-myc are higher in colorectal cancer tissue,and the expressions are related to the clinicopathological features of colorectal cancer.The expression levels of Pokemon and c-myc may predict the prognosis in patients with colorectal cancer.

Objective:To investigate the difference in efficacy between transsylvian-transinsular approach and transcortical-transtemporal approach for hematoma evacuation in the treatment of severe basal ganglia intracerebral hemorrhage in young adults.Methods:Young adult patients with severe intracerebral hemorrhage in the basal ganglia region underwent craniotomy hematoma removal in Ankang Central Hospital from February 2012 to February 2021 were retrospectively enrolled. The Glasgow Outcome Scale score was used to evaluate the outcome at 6 months after onset. 4-5 were defined as good outcome and 1-3 were defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of the poor outcomes. Results:A total of 51 patients were enrolled. Their median age was 41 (interquartile range 39-43) years, and 29 were men (56.8%). The median Glasgow Coma Scale score at admission was 6.0 (interquartile range 5.5-7.0), and the median baseline hematoma volume was 38.0 ml (34.5-47.5 ml). Twenty-one patients (41.2%) were in the transsylvian-transinsular approach group and 30 (58.8%) were in the transcortical-transtemporal approach group. There were no significant differences in demographics, vascular risk factors and baseline clinical data between the transsylvian-transinsular approach group and the transcortical-transtemporal approach group. Compared with the transcortical-transtemporal approach group, the amount of intraoperative bleeding and hematoma residue in the transsylvian-transinsular approach group were less, the proportion of patients requiring decompressive craniectomy was lower (33.3% vs. 63.3%; χ2=4.449, P=0.035), and the duration of dehydration medication and hospital stay were shorter (all P<0.05). However, there was no significant difference in the good outcome rate between the two groups (66.7% vs. 56.7%; χ2=0.518, P=0.472). Multivariate logistic regression analysis showed that lower scores of Glasgow Coma Scale at admission (odds ratio 0.128, 95% confidence interval 0.017-0.977; P=0.047) and longer hospital stay (odds ratio 1.402, 95% confidence interval 1.065-1.844; P=0.016) were independently associated with the poor outcomes. Conclusion:For young adult patients with severe basal ganglia intracerebral hemorrhage who underwent hematoma removal, although there was no significant difference between the outcomes of patients with transsylvian-transinsular approach and transcortical-transtemporal approach, the former had more advantages.

OBJECTIVETo investigate the application of 3D printing and digital technology in preoperative assessment and planning of internal fixation surgery for complex tibial plateau fracture.

METHODSComplex tibial plateau fractures and commonly used plates for tibial plateau were imaged using computed tomography (CT) to reconstruct the 3D fracture and plate models. The 3D models were used to perform virtual reduction and preoperative planning of internal fixation surgery with the most appropriate plates assisted by the 3D library of plates. According to the optimal plan, the 3D physical models of tibial plateau fractures and plates were 3D printed to simulate internal fixation operation. The effects of internal fixation were compared between the virtual surgery and the simulated surgery based on the 3D models.

RESULTSThe effects of internal fixation in the simulated surgery based on the 3D models were consistent with those of the virtual surgery. No significant difference was found in the screw length between the two surgeries.

CONCLUSIONThe combination of 3D printing and digital design can improve the effects of internal fixation for complex tibial plateau fractures.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

OBJECTIVES: To evaluate curative effects of coronavirus disease 2019 (COVID-19) patients by the transfusion of other convalescent plasma. METHODS: Retrospective analysis of the clinical data of 18 patients with severe and critical COVID-19, who were hospitalized in the ICU of Xianghu Branch of the First Affiliated Hospital of Nanchang University from February 1 to March 15, 2020. Patients were subdivided into an experimental group (=6, who had transfused the plasma) and an observation group (=12, who had no plasma transfusion). Basic clinical data and prognosis indexes of these two groups were compared. Moreover, for the experimental group, the dynamic changes of blood oxygen saturation before and after the transfusion, the changes of lymphocyte absolute value 48 hours after the transfusion, and the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid were analyzed. RESULTS: There were no significant differences in age, gender, blood type and other basic clinical data between the two groups (all >0.05).There were no significant differences in ventilator machine weaning time, extracorporeal membrane oxygenation (ECMO) weaning time, body temperature recovery to normal time, and hospitalization days between these two groups (all >0.05). For the experimental group, before, during and after the convalescent plasma transfusion, the blood oxygen saturation of all 6 patients at all time (1, 6, 8, 12, 24, 36, and 48 h) was more than 90%, and there was no significant fluctuation. There were 3 patients whose absolute value of lymphocyte was increased 48 hours after the transfusion, and the remaining was decreased. There were 5 patients whose SARS-CoV-2 nucleic acid detection turned negative 48 hours after the transfusion, accounting for 83.3%. CONCLUSIONS Transfusion of convalescent plasma will not affect outcomesof COVID-19 patients, which can neutralize SARS-CoV-2 in patients and reduce the loading capacity of SARS-CoV-2.
