Objective To investigate the expression of hepatocyte nuclear factor-1α (HNF-1α) and hepatocyte nuclear factor-4α (HNF-4α) in human hepatocellular carcinoma (HCC) and explore the function of HNF-1α and HNF-4α during HCC carcinogenesis and development. Methods Twenty-six specimens of hepatocellular carcinoma were collected. The expressions of HNF-1α and HNF-4α in HCC tissues and adjacent non-cancerous tissues were detected by reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry staining. Results The mRNA levels of HNF-1α and HNF-4α were significantly lower in HCC tissues than that in adjacent non-cancerous tissues (0.818±0.371 vs. 0.383±0.102 for HNF-1α, P<0.05;0.846±0.384 vs. 0.397±0.105 for HNF-4α, P<0.05).The positive rates of HNF-1α and HNF-4α protein were significantly lower in HCC tissues than in adjacent non-cancerous tissues (92.3% vs. 42.3% for HNF-1α, P<0.05;96.2% vs. 50.0% for HNF-4α, P<0.05). The mRNA and protein expressions of HNF-1α and HNF-4α were correlated with tumor differentiation (P<0.05). There was a negative correlation between HNF-1α and HNF-4α mRNA expressions in HCC tissues.Conclusion The expressions of HNF-1α and HNF-4α are down-regulated in HCC, which might be related to carcinogenesis and development of HCC.

Objective To discuss the safety and effectiveness of robot-assisted thyroidectomy using Da Vinci system.Methods Endoscopic thyroidectomy assisted by Da Vinci system was performed in 20 patients,including 5 cases of thyroidadenoma,4 cases of nodular goiter,and 11 cases of thyroid carcinoma.The max diameter of thyroid lump is 5.33 cm.Among 9 cases of benign thyroid neoplasm,5 cases underwent unilateral subtotal lobectomy,and 4 cases underwent unilateral near total thyroidectomy.Among 11 cases of thyroid carcinoma,7 cases underwent bilateral near total thyroidectomy,and 4 cases underwent bilateral total thyroidectomy,at the same time,all the 11 cases underwent central region lymph node dissection.Results The robot-assisted endoscopic thymidectomy was successfully carried out in 20 cases.The mean operation time was 206.4 (105~372)min.The mean operative blood loss was 27.3 ml.The draining tube was moved 3 to 6 days after surgery.The mean postoperative hospital stay was 4.9 days.The mean hospital expense was 60 172 yuan RMB.No complication occurred.20 patients were satisfied with the cosmetic effect and compararive curative effect.Conclusions The robot-assisted endoscopic thymidectomy is an efective method for thyroid diseases.The methed can get more clear vision,higher safety,and good cosmetic efect.

Objective:To improve the understanding of the diagnosis and treatment of early T-cell precursor acute lymphoblastic leukemia (ETP-ALL).Methods:The clinical data of a patient with ETP-ALL who was misdiagnosed as peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) admitted to the Second Hospital of Lanzhou University in October 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient who presented "inguinal lymphadenopathy" as the first symptom underwent lymph node biopsy and pathological examination at local hospital, and he was diagnosed as PTCL-NOS according to the consultation of another 2 hospitals. After 2 courses of chemotherapy (CHOPE regimen, GLD regimen, unknown specific medication and dosage), the therapeutic efficacy was poor. For further diagnosis and treatment, this patient came to Lanzhou University Second Hospital. Flow cytometry found blast cells in the bone marrow, and then other related examinations were completed, he was finally diagnosed as ETP-ALL. The chemotherapy regimens of Hyper-CVAD and EA were alternatively used, progressive disease (PD) occurred after 3 courses of treatment, and chidamide was added in the 4th and 5th courses of treatment, the disease still progressed, and the patient died after follow-up. The disease course of the patient was about 12 months.Conclusions:ETP-ALL has unique immunophenotypic characteristics. ETP-ALL patients have a low remission rate after conventional induction therapy, high recurrence rate and poor prognosis. Currently, there is no effective standard treatment regimen, and allogeneic hematopoietic stem cell transplantation or timely addition of new drugs may improve the prognosis.

BackgroundThe existing tools in China for assessing psychiatric nurses' knowledge, attitude and practice towards the use of protective restraint do not sufficiently consider the specialty in psychiatric practice, and the scale items are somewhat cumbersome to use, which together restrict their further promotion and application. Accordingly, there is an urgent need for developing a more scientific assessment tool. ObjectiveTo construct a scale for assessing psychiatric nurses' knowledge, attitude and practice towards the use of protective restraint and to verify its reliability and validity, so as to provide a generic tool for the assessment. MethodsBased on the theoretical framework of the knowledge-attitude-practice model, the preliminary scale was formed through systematic literature review, qualitative interview and Delphi method. From July to December 2021, a stratified sampling was utilized to select 729 psychiatric nurses from tertiary, secondary and primary (including unclassified medical institutions and grassroots hospitals) psychiatric hospitals in Guangdong Province. The formal scale was developed through item analysis, exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated by content validity and structure validity, and the reliability was verified by procedures including Cronbach's α coefficient, test-retest reliability, and split-half reliability. ResultsA total of 12 items of three dimensions (knowledge, attitude, practice) were included in the scale for assessing psychiatric nurses' knowledge, attitude and practice towards the use of protective restraint. The scale-level content validity index (S-CVI) was 0.941, and the item-level content validity index (I-CVI) ranged from 0.812 to 1.000. Exploratory factor analysis extracted three common factors, and the cumulative variance contribution rate was 62.948%. The confirmatory factor yielded adequate fit. Cronbach's α coefficient was found to be 0.887 for the scale, 0.819 for knowledge dimension, 0.842 for attitude dimension, and 0.831 for practice dimension. The split-half reliability and test-retest reliability for the scale were 0.712 and 0.922, respectively. ConclusionThe scale shows satisfactory reliability and validity, which can be used to assess psychiatric nurses' knowledge, attitude and practice towards the use of protective restraint.
