Objective To provide a longitudinal evaluation tool based on the frequency of aggressive be-havior for the aggression assessment of schizophrenia patients.Methods The Life History of Aggression was translated and revised to form the Life History of Aggression-Chinese Version(LHA-CV)based on 369 patients diagnosed with schizophrenia in the Chengdu community and compulsory medical insti-tution.The reliability of LHA-CV was analyzed by means of split-half reliability,test-retest reliability and inter-evaluator consistency.The validity was analyzed by item analysis,construct validity and crite-rion validity.Results Item analysis found that LHA-CV had good homogeneity and discriminant validity.Exploratory factor analysis found that the Kaiser-Meyer-Olkin(KMO)test value was 0.80,and the Bartlett's sphericity test χ2=1203.46(P<0.05),and it revealed four factors including non-physical ag-gression,physical aggression,self-directed aggression and antisocial behavior/consequences.The factor loadings for all 11 items were greater than 0.40.Confirmatory factor analysis was performed on the factor model,Chi-square degree of freedom(χ2/df)was 3.61,root mean square error of approxima-tion(RMSEA)was 0.07,goodness-of-fit index(GFI)was 0.92,comparative fit index(CFI)was 0.90,incremental fit index(IFI)was 0.90,and the discriminant validity of each factor was good.The criterion validity test showed the total score of LHA-CV was positively correlated with the aggressive behavior level of MacArthur Community Violence Instrument,the total score of Buss-Perry Aggression Scale,and the score of Antisocial Personality Disorder Subscale of Personality Diagnostic Question-naire-4th Edition Plus(PDQ-4+_ASPD,P<0.05).The Cronbach's α coefficient of non-physical aggres-sion,physical aggression,self-directed aggression,antisocial behavior/consequences and LHA-CV total score were 0.82,0.73,0.74,0.56 and 0.79,respectively.The test-retest reliability,Spearman-Brown split-half reliability and intra-class correlation coefficient of LHA-CV total score were 0.82(P<0.05),0.66 and 0.99,respectively.Conclusion LHA-CV has good reliability and validity,and can be used as an evaluation tool for longitudinally assessing aggressive behavior in schizophrenia patients.

Objective To investigate the clinical characteristics and prognosis of acute myeloid leukemia(AML)patients with PTPN11 gene mutation.Methods Total 115 adult AML patients who underwent initial diagnosis,treatment,and second-generation sequencing(NGS)detecting at hospital were recruited in this study.Clinical da-ta included disease characteristics,treatment efficacy,long-term prognosis,immune cell subpopulations,and leu-kemia stem cells were collected to analyze the clinical characteristics and prognosis of AML patients with PTPN11 gene mutation.Results PTPN11 gene mutation rate in newly diagnosed adult AML was 9.57％,and the mutation site mainly occurred in exon 3 region with all mutation type being point mutation.Compared with PTPN11 wild-type group,PTPN11 gene mutation group had a higher early mortality rate(18.18％vs 4.00％,P=0.048),a lower complete response rate(33.33％vs 67.71％,P=0.039),a higher recurrence rate(83.33％vs 42.31％,P=0.043),a shorter median overall survival time(9 months vs 20 months,P=0.026),a lower proportion of ef-fector T cells[(1.39±0.12)％vs(3.56±0.46)％,P=0.038],and a higher proportion of leukemia stem cells[(13.82±3.66)％vs(3.87±1.40)％,P=0.021].Conclusion PTPN11 gene mutation is a poor prognostic marker for AML.Those patients have a high early mortality rate,low complete remission rate,high recurrence rate,short median overall survival time,a low proportion of effector T cells,and a high proportion of leukemia stem cells.

The odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees was analyzed and the relationship between the odor variation and the mildewing degree was explored. A fast discriminant model was established according to the response intensity of electronic nose. The α-FOX3000 electronic nose was applied to analyze the odor fingerprint of Pollygonati Rhizoma samples with different mildewing degrees and the radar map was used to analyze the main contributors among the volatile organic compounds. The feature data were processed and analyzed by partial least squares discriminant analysis(PLS-DA), K-nearest neighbor(KNN), sequential minimal optimization(SMO), random forest(RF) and naive Bayes(NB), respectively. According to the radar map of the electronic nose, the response values of three sensors, namely T70/2, T30/1, and P10/2, increased with the mildewing, indicating that the Pollygonati Rhizoma produced alkanes and aromatic compounds after the mildewing. According to PLS-DA model, Pollygonati Rhizoma samples of three mildewing degrees could be well distinguished in three areas. Afterwards, the variable importance analysis of the sensors was carried out and then five sensors that contributed a lot to the classification were screened out: T70/2, T30/1, PA/2, P10/1 and P40/1. The classification accuracy of all the four models(KNN, SMO, RF, and NB) was above 90%, and KNN was most accurate(accuracy: 97.2%). Different volatile organic compounds were produced after the mildewing of Pollygonati Rhizoma, and they could be detected by electronic nose, which laid a foundation for the establishment of a rapid discrimination model for mildewed Pollygonati Rhizoma. This paper shed lights on further research on change pattern and quick detection of volatile organic compounds in moldy Chinese herbal medicines.

This study aims to explore the consistency between macroscopic identification and DNA barcoding identification of Amomi Fructus. With the DNA barcoding identification results, we evaluated the reliability of identifying Amomi Fructus quality by combining macroscopic traits with main volatile chemical components. Thirteen batches of Amomi Fructus samples were collected for identification. Firstly, the morphological and sensory characteristics of each sample were observed and recorded according to the standard in Chinese Pharmacopoeia(2020 edition). The 100-fruit weight, longitudinal diameter, transverse diameter, and longitudinal diameter-to-transverse diameter ratio were measured, which correspond to large, solid, and full kernel representing good quality in the sensory evaluation. The odor value detected by electronic nose and major volatile components(borneol, camphor, limonene, and borneol acetate) correspond to the sensory evaluation of strong odor representing good quality. Secondly, DNA barcoding was employed to identify the 13 batches of samples. Finally, clustering analysis was performed for the main volatile components and macroscopic traits, and the identification results were compared with those of DNA barcoding. Except two batches of samples(No.6 and No.10), the macroscopic identification showed the results consistent with those of DNA barcoding, with an identification rate of 84.62%. The clustering results of the content of four volatile chemical components and macroscopic traits were also consistent with the DNA barcoding identification results. DNA barcoding can verify the results of macroscopic identification and provide a scientific basis for the inheritance and development of macroscopic identification. Moreover, the combination of macroscopic traits and chemical components demonstrates higher accuracy in the quality evaluation of Chinese medicinal materials.

OBJECTIVE: To investigate the effect of recombinant human granulocyte colony stimulating factor (rhG-CSF) on the clinical efficacy and flow cytometry (FCM) minimal residual disease (MRD) of patients with acute myeloid leukemia (AML) after initial induction therapy in the real world. METHODS: The clinical data of 44 AML patients who were diagnosed for the first time in the Department of Hematology, The Second Hospital of Anhui Medical University, and received the initial induction therapy were retrospectively analyzed. According to whether rhG-CSF was used after treatment, these patients were divided into control group and therapy group. The complete remission (CR) rate, duration of neutropenia, incidence of infection, duration of fever, cost of antibiotics drugs, length of hospital stay, FCM MRD, and relapse-free survival (RFS) time were compared between the two groups. RESULTS: The CR rate in the control group was 60%, and 74% in the therapy group (P=0.3429). The duration of neutropenia was (21.28±7.91) days in the control group and (14.79±3.07) days in the therapy group (P=0.0016). The duration of fever was (12.80±7.31) days in the control group and (9.11±7.48) days in the therapy group (P=0.0136). While, there were no statistically significant differences between the two groups in the incidence of infection, cost of antibacterial drugs, length of hospital stay and RFS time (all P>0.05). In addition, it is particularly noteworthy that among the patients who finally obtained CR in the therapy group, 66% of them had myeloid precursor cells detected by peripheral blood FCM (accounting for 2.25%±0.99%) at the time of the first release of neutropenia, which was easy to be misdiagnosed as MRD positive. CONCLUSION rhG-CSF not only don't affect the clinical remission rate after the initial induction treatment of AML, but also significantly shortens the time of duration of neutropenia and fever, however, it may affect the analysis of peripheral blood FCM MRD detection results when the neutropenia is released for the first time.

Objective:To improve the awareness of primary myeloid sarcoma.Methods:The clinical data of one primary myeloid sarcoma patient with first symptom involving nasopharynx who was admitted to the Second Affiliated Hospital of Anhui Medical University in June 2017 were retrospectively analyzed, and the related literature was reviewed.Results:The patient presented with nasal congestion with tinnitus; it took half a year for the myeloid sarcoma diagnosis to be clear with biopsy and immunohistochemical examinations for many times. The patient was treated with chemotherapy regimens for acute myeloid leukemia (AML). Isolated myeloid sarcoma relapsed with skin masses after remission for more than 2 years. Further improvement of the bone marrow-related examinations showed that the bone marrow was not involved, and it was still isolated myeloid sarcoma. The skin mass disappeared completely after the induction chemotherapy of AML. Six months after the recurrence, the patient was in stable condition and was still under follow-up treatment.Conclusions:The primary nasopharyngeal myeloid sarcoma lacks specificity and is easy to be misdiagnosed. The prognosis of isolated myeloid sarcoma is better than that of AML. Isolated recurrence after chemotherapy remission is rare, and usually progresses to the leukemia stage quickly. Early and correct diagnosis is very important for the prognosis, and clinicians should improve the awareness of primary myeloid sarcoma.

Objective To compare the efficacy and safety of induction therapy in 3+7 protocol and 3+10 protocol in children with acute myeloid leukemia (AML). Methods Two protocols were carried out in our hospital during January 2010 to January 2015, namely 3+7 protocol(AML-06,A group) and 3+10 protocol (modified AML protocol, B group). A total of 56 cases aged from 1 year-old to 13 year-old were enrolled in A group with male to female ratio at 31:25. Five of them were classified as FAB M1, 25 as M2, 11 as M4, 10 as M5, 2 as M6 and 3 as M7. Another 44 cases aged from 1 year to 12 years were enrolled in B group with a male to female ratio at 26:18, and 17 cases were classified as FAB M2, 14 as M4, 9 as M5, 2 as M6, and 2 as M7. Efficacy and adverse events were compared between the two groups. Results The complete remission rate (CR) of B group was 70.4%, while CR in A group was 48.2%. Considering the CR, 3+10 protocol showed higher efficacy than 3+7 protocol (P< 0.05). The major adverse event was bone marrow suppression. Treatment-related mortality (TRD) in A group was 1.8%, which was lower than that in B group (2.3%). The overall survival rate in A group was 75.0%, which was lower than that in B group (86.4%, P< 0.05). Conclusions The induction therapy of 3+10 protocol and 3+7 protocol showed effectiveness for AML treatment. The 3+10 protocol showed a higher CR than 3+7 protocol with no TRD increase, indicating that the 3+10 protocol should be recommended for AML treatment in children.

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

BACKGROUND: The perioperative hemorrhage of knee surgeries is a difficulty in clinic, and the efficacy of tranexamic acid to reduce postoperative bleeding has attracted more attention, but choosing which administrations remains controversial. OBJECTIVE: To investigate the efficacy of tranexamic acid by intravenous injection or articular injection for reducing the perioperative hemorrhage of total knee arthroplasty. METHODS: Sixty patients undergoing unilateral total knee replacement were enrolled, and were then randomized into three groups (n=20 per group): no tranexamic acid administration (group A); intravenous dropping of 15 mg/kg tranexamic acid before tourniquet application plus 10 mg/kg tranexamic acid at 3 hours postoperatively (group B); articular injection of 50 mL saline diluted with 1 g tranexamic acid through a drainage tube (group C). Two-hour closure of drainage tube was performed in all patients. The postoperative dominant and hidden blood loss, blood transfusion rate, pulmonary embolism as well as lower extremity deep venous thrombosis were recorded. RESULTS AND CONCLUSION: (1) The dominant and hidden blood loss in the groups B and C were significantly less than those in the group A (P < 0.05); the dominant blood loss showed no significant difference between groups B and C (P > 0.05); the group B exhibited a significantly less hidden blood loss compared with group C (P < 0.05). (2) The blood transfusion rate in the groups B and C was significantly lower than that in the group A (P < 0.05). (3) No pulmonary embolism or lower extremity deep venous embolism occurred during 3-month follow-up. (4) That is to say, tranexamic acid can obviously reduce perioperative blood loss and blood transfusion rate without pulmonary embolism or lower extremity deep venous thrombosis, and intravenous administration exerts better clinical effectiveness.

Objective To discuss the role of FAT2 gene in the ovarian epithelial carcinoma (OEC) and predict and analyze the possible mechanism and clinical value of FAT2 in the occurrence and development of ovarian cancer. Methods Data of 311 patients with OEC in the TCGA database were analyzed by cbioprotal online analysis platform. Kaplan-Meier method was used to analyze the relationship between the FAT2 genetic alteration and ovarian cancer survival. The FAT2 gene related proteins, protein network and enrichment analysis were performed by GeneCards database. Results In 311 patients, mutation of FAT2 gene was found in 12 patients with a mutation rate of 4%, amplification in 7 cases (2.3%), multiple mutations in 3 cases (1%) and deletion in 2 cases (0.6%). Kaplan-Meier curve showed that the total survival of patients with FAT2 genetic alteration was significantly longer than that in patients without FAT2 genetic alteration (P=0.0338). There was no significant difference in the disease-free survival time between the two groups (P=0.387). Twenty-one FAT2 related protein, such as CTNNB1, ARVCF and CTNND1 were down expressed in OEC tissues. The FAT2 related protein enrichment was analyzed, and Wnt signaling pathway, cell-cell adhesion and other cell physiological activities were found. Conclusion FAT2 may play the role in cancer suppressor gene in OEC, which induces the degradation of key protein CTNNB1 in Wnt pathway. The Over expression of FAT2 might be a good prognostic factor in ovarian cancer and can be used as a potential prognostic marker and a therapeutic target.
