[Objective]To explore innovative approaches for integrating ethical culture education in traditional Chinese medicine(TCM)colleges and universities,which involves extracting elements of integrity from TCM culture to develop an ethical education program tailored for these institutions.[Methods]Applying literature research methods,this study extracts similarities between TCM culture and ethical culture.It utilizes key TCM concepts like"four diagnoses integration""differential diagnosis and treatment""good prescription""treating both the symptoms and root causes"as a framework for ethical culture education in TCM colleges and universities.[Results]TCM culture is found to contain a wealth of ethical and methodological content,showing high compatibility with ethical culture.Ethical culture education in TCM colleges and universities currently faces challenges,including a lack of comprehensive integration of the"four diagnoses",insufficient"differential diagnosis and treatment",limited use of"good prescriptions"and a weak foundation in"treating both the symptoms and root causes".It is necessary to further improve the achievements of clean culture education in TCM colleges and universities by using measures such as finding out the reality of clean ideology education,improving the clean culture education system,skillfully carrying out clean culture education,and building a solid line of clean culture education.[Conclusion]Through case study of Zhejiang Chinese Medical University provides insights into the current state of ethical education.It emphasizes the need to improve the ethical culture education system,execute ethical culture education strategically and strengthen the ethical education defense line.These findings could serve as a model for ethical culture education in universities.

30 patients with chronic periodontitis and Type 2 diabetes mellituse were included.By a split-mouth design,the teeth in the left side were served as the experiment group and given Nd∶YAG and Er∶YAG laser therapy adjunctive to conventional periodontal treatment;the teeth in the right side were served as the control group and given conventional periodontal treatment alone.Before and after treatment perio-dontal and CBCT image indexes were examinde and compare between the 2 groups.Before treatment all the indexes were not statistically dif-ferent between the 2 groups(P＞0.05).3 months after treatment,the bleeding index(BI)and probing depth(PD)of the experimental group were significantly lower than those of the control group(P＜0.05).6 months after treatment,BI,PD and attachment loss(AL)in the experi-mental group were significantly lower than those in the control group,and the surface area and volume of the root in the alveolar bone were significantly higher than those in the control group(P＜0.05).Nd∶YAG and Er∶YAG laser therapy adjunctive to conventional periodontal treatment is more effective than conventional periodontal treatment alone in the treatment of chronic periodontitis with type 2 diabetes melli-tus.

Objective: To analyze the trend and characteristics of school tuberculosis epidemic in Shijiazhuang from 2011 to 2020, and to provide reference for school tuberculosis prevention and control. Methods: Descriptive methods were used to analyze the epidemiological characteristics of tuberculosis among students and the epidemic situation of tuberculosis in schools in Shijiazhuang from 2011 to 2020. The χ 2 test and χ 2 trend test were used to analyze the characteristics and trend of school tuberculosis. Results: A total of 4 896 cases of tuberculosis were registered among students in Shijiazhuang from 2011 to 2020. The average annual registered incidence rate of students was 24.69/100 000, and the difference in incidence rate was statistically significant ( χ 2=318.50, P <0.01) the overall registered incidence rate of tuberculosis among students in the past 10 years was on the rise ( χ 2 trend =87.79, P <0.01). Among the student cases, male accounted for 53.89%, female accounted for 46.11%. The age group of students aged >18 and above accounted for the largest proportion(50.35%), followed by the age group aged 16-18( 35.80 %). Most students cases occurred in April and September-November, with September the highest(12.03%). A total of 22 clustered outbreaks (174 cases) and the aggregate epidemic accounted for 3.55% of the total number of students with tuberculosis. Conclusion The prevention and control of tuberculosis epidemic in schools in Shijiazhuang should not be underestimated, and strengthen the supervision, management, publicity and education of students in key age groups to avoid clusters of outbreaks.

Objective:To investigate the efficacy and safety of geritinib in the treatment of acute myeloid leukemia (AML) with FLT3 mutation.Methods:The clinical data of 5 AML patients with FLT3 mutation who were diagnosed in the University of Hong Kong-Shenzhen Hospital, Shenzhen People's Hospital, Shenzhen Second People's Hospital, Shenzhen University General Hospital from March 2020 to April 2021 were retrospectively analyzed. Relapsed patients concurrently received two- or three-drug chemotherapy combined with geritinib. Blood routine was checked once a week; liver function and renal function were checked once every 2 weeks during treatment. Bone marrow puncture was performed once every 1 to 3 months to monitor the bone marrow morphology, minimal residual disease (MRD) and FLT3 mutation expression levels. The efficacy, side effects, overall survival of these patients were analyzed after treatment with geritinib.Results:The white blood cell was increased in all the 5 patients at the initial diagnosis. FLT3 mutations analysis showed FLT3-internal tandem duplication (ITD) (3 cases) and FLT-3 tyrosine-kinase domain (TKD) (2 cases). Among 5 patients, 1 patient was relapse-free with maintenance therapy of oral geritinib after hematological stem cell transplantation (HSCT) for 60 days; among other 4 relapsed and refractory patients, 1 female patient after pregnancy relapsed after transplantation and then achieved complete remission followed by the maintenance therapy with geritinib after oral geritinib, 1 16-year-old patient achieved treatment outcome close to the complete remission after treatment with geritinib, 1 patient achieved complete remission after treatment with geritinib, and then underwent haplo-HSCT followed by the maintenance therapy with geritinib and the other 1 relapsed patient achieved complete remission after treatment with geritinib. After transplantation, 3 patients receiving maintenance treatment of geritinib did not relapse. The main side effects included anemia, decreased neutrophil count, rash, and increased aminotransferase. The median follow-up time of 5 patients was 15 months (6-20 months). All 5 cases survived until the last follow-up in November 2021 and 4 patients were disease-free.Conclusions:Relapsed and refractory AML patients with FLT3 mutation can achieve complete remission after treatment with geritinib and get a chance for transplantation. Geritinib may reduce the risk of recurrence after transplantation and improve survival rate. No serious side effects occur in geritinib treatment.

Objective:To construct a three-dimensional imaging model of the pancreatic head based on the embryological fusion plane, and to provide morphological parameters of the pancreatic head for future developments of basic and clinical researches on the pancreas.Methods:Histologic cross-sections of the pancreatic head with its adjacent structures were made from healthy cadavers. Immunohistochemical analysis of pancreatic polypeptide antibody was then performed to verify the existence and location of the embryological fusion plane reported previously. The histologically positioning method of the embryological fusion plane was then applied to the corresponding sections on computed tomography (CT). Based on the results of the above work, volunteers from the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University were then used as research objects. A three-dimensional visualization reconstruction software was used to perform CT image-based structures to include the abdominal pancreas, dorsal pancreas head, and embryo fusion surface. Three-dimensional reconstruction of the pancreatic head, and morphological measurements of the relevant structures of the pancreatic head were then made.Results:Immunohistochemical analysis verified the existence and the position of the embryological fusion plane. The histologically positioning method was then successfully applied to the CT sections. The three-dimensional imaging model of the pancreatic head containing the embryological fusion plane, dorsal segment and ventral segment of head were built based on CT images. A total of 35 volunteers were included, including 19 males and 16 females, aged (48.26±8.26) years, and with a BMI of (22.29±1.78) kg/m 2. The morphological results showed that the volume of the pancreatic head, dorsal pancreas and abdominal pancreas were (32.80±8.15) cm 3, (22.21±6.94) cm 3, (10.59±3.87) cm 3, and the area of the embryo fusion surface was (12.46±3.20) cm 2. All volunteers were then grouped according to gender. Statistical analysis showed that there were no significant differences in the total pancreatic head volume, dorsal pancreatic head volume, abdominal pancreatic volume, and embryo fusion area among the groups ( P>0.05). Conclusions:It was feasible and practical to build a three-dimensional imaging model of the pancreatic head based on the embryological fusion plane by using a 3D computer system. This model and its morphological parameters could provide a new tool for research on pancreas.

Objective To analyze the clinical features of patients with coronavirus disease 2019 (COVID-19) in Shanghai and to investigate the risk factors for disease progression to severe cases. Methods The clinical data of 292 adult patients with COVID-19 hospitalized in Shanghai Public Health Clinical Center from January 20, 2020 to February 10, 2020 were retrospectively analyzed, including 21 severe patients and 271 mild patients. The demographic characteristics, epidemiological history, history of underlying diseases and laboratory examinations were compared between the two groups. Measurement data were compared using t test or Mann-Whitney U test. The count data were compared using hi-square test. The binary logistic regression equation was used to analyze the risk factors for the progression of patients to severe cases. Results Among the 292 patients, 21 were severe cases with the rate of 7.2% (21/292). One patient died, and the mortality rate was 4.8% in severe patients. The severe patients aged (65.0±15.7) years old, 19 (90.5%) were male, 11 (52.4%) had underlying diseases, 7 (33.3%) had close relatives diagnosed with COVID-19. The mild patients aged (48.7±15.7) years old, 135 (49.8%) were male, 74 (27.3%) had underlying diseases, 36 (13.3%) had close relatives diagnosed with COVID-19. The differences between two groups were all significant statistically ( t =-4.730, χ 2 =12.930, 5.938 and 4.744, respectively, all P <0.05). Compared with the mild patients, the levels of absolute numbers of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine, serum cystatin C, C reactive protein (CRP), procalcitonin , D -dimer, pro-B-type natriuretic peptide (proBNP), serum myoglobin, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum troponin I (cTnI) in severe patients were all significantly higher ( U =2 091.5, 1 928.0, 1 215.5, 729.0, 1 580.5, 1 375.5, 917.5, 789.5, 1 209.0, 1 434.0, 638.0, 964.5, 1 258.0 and 1 747.5, respectively, all P <0.05), while the levels of lymphocyte count, albumin, transferrin, CD3 + T lymphocyte count, CD8 + T lymphocyte count and CD4 + T lymphocyte count in severe patients were all significantly lower ( U =1 263.5, t =4.716, U =1 214.0, 962.0, 1 167.5 and 988.0, respectively, all P <0.05). Further logistic regression analysis showed that the albumin (odds ratio ( OR )=0.806, 95% CI 0.675-0.961), CRP ( OR =1.016, 95% CI 1.000-1.032), serum myoglobin ( OR =1.010, 95% CI 1.004-1.016), CD3 + T lymphocyte count ( OR =0.996, 95% CI 0.991-1.000) and CD8 + T lymphocyte count ( OR =1.006, 95% CI 1.001-1.010) at admission were independent risk factors for the progression of COVID-19 patients to severe illness (all P <0.05). Conclusions Severe cases of patients with COVID-19 in Shanghai are predominantly elderly men with underlying diseases. Albumin, CRP, serum myoglobin, CD3 + T lymphocyte count and CD8 + T lymphocyte count could be used as early warning indicators for severe cases, which deserve more clinical attention.

Objective To investigate the effect of Ⅲ-type phosphatidylinositide 3 kinase (PI3K) pathway adjusting autophagy on brain damage mechanism after cardiopulmonary resuscitation (CPR) and hypothermia treatment.Methods The asphyxia induce cardiac arrest-CPR model was reproduced on healthy male Sprague-Dawley (SD) rats.Sixty rats after restoration of spontaneous circulation (ROSC) were randomly divided into normothermia group,therapeutic hypothermia group and PI3K inhibitor 3-methyl adenine (3-MA) pretreatment group,differentiated by 24 hours and 48 hours after ROSC.Each group had 10 rats at each time point.The anal temperature in the normothermia group was maintained at (37.0 ± 0.2) ℃,and the rats in the hypothermia group were given cooling treatment immediately after ROSC,and the target rectal temperature was 32-34 ℃.In the 3-MA pretreatment group,10 mmol/L 3-MA 5 μL was injected into the ventricle 20 minutes before asphyxia,and other groups were given the same amount of normal saline.Ten rats without CPR were included in Sham group only received anesthesia and catheterization.The rats were sacrificed at 24 hours and 48 hours after ROSC respectively,and the brain tissues were harvested,the brain water content (BWC) was measured by dry-wet weight method.Western Blot was used to determine the autophagy related proteins Beclin-1 and microtubule-associated protein 1 light chain 3 (LC3),apoptosis related proteins Bcl-2 and caspase-3,and the Ⅲ-type PI3K pathway proteins Vps34 and Atgl4.Ultrastructural changes in brain tissue were observed with transmission electron microscope.Neurological deficit scores (NDS) was obtained in each group at 48 hours after ROSC.Results Compared with Sham group,the cortex at 24 hours after ROSC in normothermic group showed obvious edema,apeptosis and autophagy began to appear under transmission electron microscope,and the expressions of autophagy,apoptosis and Ⅲ-type PI3K-related proteins in brain tissue were significantly increased in a time-dependent manner,and the neurological function at 48 hours after ROSC was significantly damaged.After hypothermia intervention,brain edema of rats was significantly reduced,no obvious apoptosis was found,but autophagy was increased,the expressions of autophagy-related proteins Vps34,Atg14 and Ⅲ-type PI3K-related proteins Beclin-1 and LC3 at 48 hours after ROSC were further higher than those of normothermic group (Vps34/GAPDH:0.25±0.03 vs.0.15±0.04,Atg14/GAPDH:0.12±0.03 vs.0.05±0.04,Beclin-1/GAPDH:0.060±0.002 vs.0.018±0.002,LC3-Ⅱ/GAPDH:0.160±0.010 vs.0.050± 0.010,all P ＜ 0.05),the expressions of apoptosis related proteins Bcl-2 and caspase-3 were significantly lowered (Bcl-2/GAPDH:0.05±0.03 vs.0.20±0.04,caspase-3/GAPDH:0.050±0.002 vs.0.140±0.015,both P ＜ 0.05),neurological function was significantly improved (NDS:157±85 vs.343± 198,P ＜ 0.05).Pretreatment with 3-MA inhibited the protective effect of hypothermia on brain tissues.The expressions of Vps34,Atg14,Beclin-1 and LC3 in brain tissues at 48 hours after ROSC in 3-MA pretreatment group was significantly lower than those in the hypothennia group (Vps34/GAPDH:0.18±0.03 vs.0.25±0.03,Atg44/GAPDH:0.07±0.04 vs.0.12±0.03,Beclin-1/GAPDH:0.015±0.003 vs.0.060±0.002,LC3-Ⅱ/GAPDH:0.045±0.030 vs.0.160±0.010,all P ＜ 0.05),the expressions of Bcl-2 and caspase-3 were significantly increased (Bcl-2/GAPDH:0.15±0.04 vs.0.05±0.03,caspase-3/GAPDH:0.120±0.015 vs.0.050±0.002,both P ＜ 0.05),and NDS score was significantly increased (341±208 vs.157±85,P ＜ 0.05).Conclusion Hypothermia treatment reduced brain edema and ameliorated brain function after CPR,which might be related to increase autophagy and inhibit apoptosis adjustment by activating Ⅲ-type PI3K pathway.

The higher levels of the knowledge and attitude of salt reduction for hypertension prevention,the higher level of the practice.

Objective: To evaluate the diagnostic value of three-dimensional multi-slice spiral computed tomography (CT) imaging in Crohn's disease(CD) of small intestine and its active and remission stages. Methods: The clinical and CT data of 34 patients with Crohn's disease confirmed by digestive endoscopy were retrospectively analyzed. According to whether the lesions were active, the patients were divided into active group (25 cases) and remission group (9 cases). The difference of CT signs between the two groups was compared. Chi square test was used to evaluate the diagnostic efficiency of CT three-dimensional imaging for polyps and their activity evaluation of Crohn's disease. Results: The incidences of intestinal wall stratification, moderate enhancement, severe enhancement, ulcer, cellulitis, lymph node enlargement and wood comb sign in active group were higher than those in remission group (χ²=20.193, 9.018, 4.986, 3.947, 9.551, 4.986, 6.766, 4.986 respectively, P<0.05). The incidence of intestinal wall monolayer thickening, non-enhancement, mild enhancement and abdominal abscess in remission group was higher than that in active group, with significant difference (χ²=15.092, 13.768, 25.336, 16.996, P<0.05). while there were no significant difference between the two groups in the incidence of pneumoperitoneum, intestinal stenosis and enlargement (P>0.05). Conclusions Spiral CT three-dimensional reconstruction imaging can show the intestinal wall thickening, intestinal lesions and parenteral complications of Crohn's disease comprehensively, carefully and intuitively, and play an important role in guiding clinical treatment by evaluating the active and remission stages of CD.
