Chemotherapy is an important treatment for tumors， but most patients experience varying degrees of chemotherapy- induced myelosuppression. Four properties theory of traditional Chinese medicine （TCM） has unique advantages in improving chemotherapy-induced myelosuppression. The monomers from TCM with different properties and flavors， such as cold-natured （e.g. Scutellaria baicalensis， Rhus chinensis）， cool-natured （e.g. Ligustrum lucidum， Ophiopogon japonicus）， warm-natured （e.g. Panax ginseng， Epimedium brevicornu， Curcuma longa， Angelica sinensis）， hot-natured （e.g. Cinnamomum cassia， Aconitum carmichaeli）， and neutral-natured （e. g. donkey-hide gelatin， Lycium barbarum， Rhodiola rosea， fungi）， can exert anti- myelosuppressive effects by reducing damage to hematopoietic stem/progenitor cells， improving the bone marrow hematopoietic microenvironment， inhibiting the oxidative stress response， regulating signaling pathways， so as to ultimately repaire inflammatory damage and improve hematopoietic function， thereby playing an anti-myelosuppressive role.

Attenuated psychosis syndrome(APS)is a clinical disorder associated with a high risk of psychosis.Patients during this period typically exhibit multidimensional neurocognitive and social cognitive impairment.Cognitive impairment in APS patients is associated with structural and functional abnormalities in the frontal,temporal and subcortical brain regions.At present,drug therapy,psychotherapy,nutritional therapy and computer cognitive training are mainly used to improve the cognitive function of APS patients.In the future,we could comprehensively utilize brain imaging,electrophysiology,and molecular imaging to deeply explore the neuropathological mechanism of APS cognitive impairment,and combine computer,virtual reality,and artificial intelligence to develop new cognitive function intervention procedures,in order to achieve APS precise prevention and treatment.

The World Health Organization (WHO) classification serves as the internationally recognized standard for diagnosing and classifying hematopoietic and lymphoid tissue tumors(WHO-HEAM). Since 2001, it has undergone multiple upgrades and revisions, updating, clarifying, and refining previous tumor diagnostic and classification standards while incorporating numerous new genetic and molecular biological subtypes. In 2022, two classification proposals emerged due to a wealth of clinical and scientific research results: the fifth edition of the WHO hematopoietic and lymphoid tissue classification (WHO-HAEM5), published in Leukemia journal; and the International Consensus Classification (ICC), published in Blood journal. These two schemes differ in their approach to classifying hematopoietic and lymphoid tissue tumors, posing challenges for clinical laboratory diagnosis and treatment.

Early intervention contributes to improving patient experience and doctor-patient relationship in the case of non-psychiatric outpatients with psychological problems.The authors studied the psychological assessment and hierarchical management for non-psychiatric inpatients at a general hospital. Measures taken include establishing multi-disciplinary and inter-department teams, building an intra-hospital joint-action system, and implementing the psychological assessment and hierarchical management for non-psychiatric inpatients.These efforts explored ways for a general hospital in psychological counseling, offering humanistic service, and transformation of medical pattern.

Objective To explore curriculum and faculty qualification of Chongqing operating room (OR) specialty certified nurse theoretical tralning program by feedback of students, and to im-prove the quality of tralning. Method Relying on the national key project of the First Affiliated Hos-pital of Chongqing Medical University, Chongqing Health administration OR nurse specialist tralning program set additional courses related to research, teaching, patient safety and first ald tralning based on operation room specialist nurse tralning outline. 81 participants were given questionnalres issued by college of nursing after the 7th OR specialist nurse theoretical tralning, and statistics analysis was made of it. Result Effective questionnalres was100%. The overall judgment on theory tralning was high, with 92.60%of the students giving overall score above 150 points (out of 170);93.84%of students sat-isfied on teaching staff ratio while 95.06% students satisfied on course content. For the 17 items, the majority scores given by the students were ≥ 9 points (a 10-points scale), on the top of the list were item “Theoretical tralning helps to enhance professional theoretical level and guide clinical practice”“Teaching content meet needs of OR specialist nurses” “Teaching content is helpful to improve the core competence of specialist nurses” (all 96.30%, 78 out of 81), while the bottom was “Instructor create an environment which fosters student participation”(85.19%, 69 out of 81). Conclusion Chong-qing OR specialist theoretical tralning has good practical and guidance property, the content meet OR nurses needs, instructor ratio is reasonable, and students are highly satisfied with it. Instructors need to encourage students' participation in class interaction, and pay attention to improving their research capabilities.

Objective To investigate the clinical and laboratory characteristics of acute myeloid leukemia (AML) with t (16;21)(p11;q22) translocation.Methods Two patients diagnosed by morphology,cytochemical stain,immunology,cytogenetics and genetic testing.Similarities and differences of clinical characteristics and laboratory examination were analysed,along with a review of the literatures.Results According to the FAB classification,one patient was M4 and the other one was M1.The cytogenetic aberrations were 46,XY,t(16;21)(p11;q22)[16]/47,XY,t(16;21)(p11;q22),+21[4] of ease 1 and 46,XX,t(16;21)(p11;q22)[20] of case 2.Cytophagocytosis and CD56 antigen expression were found in both cases.The prognosis was poor in both cases.Conclusions AML with t(16;21)(p11;q22) is a specific type,which has unusual characteristics of morphology,immunology,cytogenetics,clinical feature.The prognosis of the patients is poor,so stem-cell transplantation maybe the only and the first choice of treatment.

Objective To study the effect of nerve growth factor(NGF)in survival of super-length random flap.Methods The experiment employed the animal model of random flap in Wistar's rat back,applied 66.7 μg NGF locally in trial group's flap at the first day after operation with auto-control.The survival proportion,skin temperature and survival rate of random flap were observed,and the blood flow,the blood flow velocity,the blood flow volume change of random flap were measured by the laser and photic-conduct fiber means in differ time.Results The survival proportion(7.12±1.54)cm2 and survival rate(92±5)%of random flap of trial group was obviously higher(P＜0.05)than those in control group[(5.23±0.19)cm2,(69±5)%]after pedicle division.The blood flow,the blood flow velocity,the blood flow volume and skin temperature in the midge and at the end of random flap in the trial group were obviously higher than those in control group 1 day after operation(P＜0.05),and the blood flow velocity in the pedicle of random flap in the trial group was increased markedly(P＜0.05).The blood flow volume and skin temperature in the pedicle of random flap in the trial group were higher than those in control group 3 days after operation(P＜0.05).The survival of randomflapinthetrial groupwere very significantly increased than those in control group 7 days after operation(P＜0.01).Conclusion NGF can increase flap's blood flow,blood flow velocity and blood flow volume,enhancing survival of the big-proportioned and super-length random flap.

Objective: To observe the distribution of inducible nitric oxide synthase (iNOS) in gingival tissues in elderly patients with periodontitis. Methods: Gingival tissue samples were obtained during tooth extraction.The localization of positive expression of iNOS in gingival tissues in 10 patients aged 65-86 years with periodontitis was tested with immunohistochemical method and was compared with that of 10 adult patients(37-54 years old) with periodontitis, 10 juvenile patients (18-29 years old) with periodontitis and 10 healthy elders(65-81 years old),respectively. Results:iNOS expression was mainly found in epithelial cells, inflammatory cells in connective tissues, granuloma tissues, epithelial basement membrane and microvascular endothelial cells in gingiva in the 3 groups of periodontitis. The cases of positive expression of iNOS in microvascular endothelial cells and inflammatory cells in connective tissues in elderly patients with periodontitis were significantly fewer than those in juvenile patients and adult patients ( P
