DBP. CONCLUSION: The cerebral complication in essential hypertension is correlated to SBP, DBP and PP. However, PP plays the most important role among the different parameters of blood pressure in the pathogenesis of the cerebral complication.

Objective Methicillin-resistant Staphylococcus aureus (MRSA) is a growing public health concern that has been associated with pediatric fatalities. This study investigated the genotypes of staphylococcal cassette chromosomal mec (SCCmec) and Panton-Valentine Leukocidin (PVL) in MRSA strains isolated from Shanghai Children's Hospital by PCR. Methods A total of 30 strains of MRSA were isolated from various clinical specimens from October 2005 to June 2006. The antimicrobial susceptibility was measured by agar diffusion method. SCCmec typing was conducted using a novel multiplex PCR assay allowing for concomitant detection of methicillin resistance (mecA gene) to facilitate detection and classification of all currently described SCCmec typesⅠ, Ⅱ, Ⅲ, Ⅳa, b, c, d andⅤ. PVL gene was also determined by PCR. Results mecA gene was positive in all the strains. SCCmecⅡ was identified in 6(20.0%) isolates, SCCmecⅢ in 15(50.0%) isolates, SCCmecⅤ in 2 and SCCmecⅣa in 1 isolate. Six MRSA strains were non-typeable. The isolates with SCCmecⅡ or SCCmecⅢ were resistant to multiple antibiotics. The strains harboring SCCmecⅣa or SCCmecⅤwere susceptible to all antibiotics except β-lactams. Eleven (36.7%) isolates were PVL positive. The genotypes and subgenotypes of staphylococcal chromosomal cassette mec of eleven PVL-positive MRSA were SCCmecⅡ(1 isolates), SCCmecⅢ (5 isolates), SCCmecⅣa (1 isolate), SCCmecⅤ (2 iso-Lates) non-typeable (2 isolates). Conclusions SCCmecⅡ and SCCmecⅢ are the major genotypes of MRSA in our hospital. These isolates are multi-resistant to antibiotics. The prevalence of PVL gene is higher in SCCmecⅡ- or SCCmeⅢ-positive MRSA. The isolates with SCCmecⅡ or SCCmecⅢ were resistant to multiple antibiotics.

Objective To establish the drug use evaluation(DUE)standard of somatostatin and evaluate the rationality of its clinical use,so as to provide a reference for the rationally clinical application of somatostatin.Methods Based on the specification of somatostatin for injection,related guidelines and literature,DUE standard was established.Evaluate the rationality and standardization of the use of somatostatin for injection at Beihai People's Hospital from January 2021 to December 2021 based on the established DUE standards.Results A total of 407 patients were included,with a medication reasonable rate of 94.84％.The irrational use of drug included unreasonable indications(13 cases,3.19％),unreasonable drug use frequency(7 cases,1.72％),and unreasonable drug interactions(1 case,0.25％).Conclusion The somatostatin for injection DUE standard established is feasible and practical.The clinical application of somatostatin for injection in this hospital is basically reasonable,but there are still some irrational use of somatostatin,which should be strengthened for intervention.

Objective To identify Chinese character writing related cortex (WRC) and its relationship with hand motor cortical areas. Methods Ten native Chinese-speaking, right-hand volunteers were recruited in the study. NTMS mapping was conducted during picture naming task. The WRC were mapped based on nTMS-induced impairment of Chinese character writing. The extent and area of WRC was calculated. The right-hand motor representations were mapped while motor-evoked potentials were produced under nTMS stimulation. EMG data and coordinates of positive stimulus were recorded. The relationship between WRC and hand motor cortex (HMC) was analyzed on the basis of area comparison and distance calculation. Results The cortical areas related to Chinese character writing were mapped successfully in all subjects by nTMS. WRC was primarily centered in left posterior middle frontal gyrus (pMFG) (86%,55/64). The mean WRC area (161.03 mm2 ±62.58mm2) was significantly smaller than the mean HMC area (589.50 mm2±227.34mm2) (P<0.001). The WRC and HMC were not conjoined or overlapped in the dominant hemisphere. The distance between those two was 12.58mm±2.71mm. Conclusions NTMS can provide reliable assistance in mapping WRC areas. The WRC is relatively fixed and centralized in pMFG but is not overlapped with the HMC.

It includes genomics, transcriptomics, proteomics and metabonomics. We elaborate the cooperative development of omics in recent years and it’s role in the genetic variation in Parkinson's disease in this article.

Objective:To investigate the effect of life review therapy on spiritual comfort and dignity among patients with advanced bladder cancer, to provide reference for the improvement of quality of death outcomes.Methods:A total of 60 patients with advanced bladder cancer who were admitted to the Cancer Hospital of the University of Chinese Academy of Sciences from March 2018 to January 2020 were selected as the research objects. Randomly divided all the patients into the control group and the experimental group, 30 cases in each group. The control group was given routine end-of-life care, and the experimental group was given 5 times of life review therapy on the basis of the control group. The effect of the intervention was evaluated by the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale(FACIT-Sp-12) and the Patient Dignity Inventory (PDI).Results:Finally, there were 28 cases in the experimental group and 29 cases in the control group. After the intervention, the scores of peace, meaning and belief demensions and total scores in FACIT-Sp-12 in the experimental group were (10.61 ± 2.23), (11.14 ± 1.90), (10.67 ± 1.79) and (32.36 ± 3.28), respectively, which was significantly higher than those in the control group (8.34 ± 2.24), (10.03 ± 1.49), (8.66 ± 1.89) and (27.03 ± 3.61), the differences were statistically significant ( t values were 2.45-5.82, all P<0.05). The psychological state, dependence, mental peace, social support demension scores and total scores of PDI in the experimental group were (8.64 ± 2.06), (3.14 ± 0.89), (4.21 ± 0.79), (2.43 ± 0.69) and (28.46 ± 4.98), which were significantly lower than those in the control group (10.34 ± 2.93), (4.17 ± 1.17), (4.93 ± 1.33), (3.17 ± 1.07) and (34.01 ± 4.79), the differences were statistically significant ( t values were 2.48-4.28, all P<0.05). Conclusions:Life review therapy can promote spiritual comfort and alleviate dignity destroyed in patients with advanced bladder cancer.

Objective:To establish a set of artificial intelligence (AI) verification rules for blood routine analysis.Methods:Blood routine analysis data of 18 474 hospitalized patients from the First Hospital of Jilin University during August 1st to 31st, 2019, were collected as training group for establishment of the AI verification rules,and the corresponding patient age, microscopic examination results, and clinical diagnosis information were collected. 92 laboratory parameters, including blood analysis report parameters, research parameters and alarm information, were used as candidate conditions for AI audit rules; manual verification combining microscopy was considered as standard, marked whether it was passed or blocked. Using decision tree algorithm, AI audit rules are initially established through high-intensity, multi-round and five-fold cross-validation and AI verification rules were optimized by setting important mandatory cases. The performance of AI verification rules was evaluated by comparing the false negative rate, precision rate, recall rate, F1 score, and pass rate with that of the current autoverification rules using Chi-square test. Another cohort of blood routine analysis data of 12 475 hospitalized patients in the First Hospital of Jilin University during November 1sr to 31st, 2023, were collected as validation group for validation of AI verification rules, which underwent simulated verification via the preliminary AI rules, thus performance of AI rules were analyzed by the above indicators. Results:AI verification rules consist of 15 rules and 17 parameters and do distinguish numeric and morphological abnormalities. Compared with auto-verification rules, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score of AI rules in training group were 22.7%, 1.6%, 74.5%, 1.3%, 75.7%, 97.2%, 93.5%, 94.7%, 94.1, respectively.All of them were better than auto-verification rules, and the difference was statistically significant ( P<0.001), and with no important case missed. In validation group, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score were 19.2%, 8.2%, 70.1%, 2.5%, 72.6%, 89.2%, 70.0%, 88.3%, 78.1, respectively, Compared with the auto-verification rules, The false negative rate was lower, the false positive rate and the recall rate were slightly higher, and the difference was statistically significant ( P<0.001). Conclusion:A set of the AI verification rules are established and verified by using decision tree algorithm of machine learning, which can identify, intercept and prompt abnormal results stably, and is moresimple, highly efficient and more accurate in the report of blood analysis test results compared with auto-vefication.

Objective:To evaluate the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with secondary acute myeloid leukemia (sAML) .Methods:In this multicenter, retrospective clinical study, adult patients aged ≥18 years who underwent allo-HSCT for sAML at four centers of the Zhejiang Hematopoietic Stem Cell Transplantation Collaborative Group from January 2014 to November 2022 were included, and the efficacy and prognostic factors of allo-HSCT were analyzed.Results:A total of 95 patients were enrolled; 66 (69.5%) had myelodysplastic syndrome-acute myeloid leukemia (MDS-AML) , 4 (4.2%) had MDS/MPN-AML, and 25 (26.3%) had therapy-related AML (tAML) . The 3-year CIR, LFS, and overall survival (OS) rates were 18.6% (95% CI 10.2%-27.0%) , 70.6% (95% CI 60.8%-80.4%) , and 73.3% (95% CI 63.9%-82.7%) , respectively. The 3-year CIRs of the M-AML group (including MDS-AML and MDS/MPN-AML) and the tAML group were 20.0% and 16.4%, respectively ( P=0.430) . The 3-year LFSs were 68.3% and 75.4%, respectively ( P=0.176) . The 3-year OS rates were 69.7% and 75.4%, respectively ( P=0.233) . The 3-year CIRs of the groups with and without TP53 mutations were 60.0% and 13.7%, respectively ( P=0.003) ; the 3-year LFSs were 20.0% and 76.5%, respectively ( P=0.002) ; and the 3-year OS rates were 40.0% and 77.6%, respectively ( P=0.002) . According to European LeukmiaNet 2022 (ELN2022) risk stratification, the 3-year CIRs of patients in the low-, intermediate-, and high-risk groups were 8.3%, 17.8%, and 22.6%, respectively ( P=0.639) . The three-year LFSs were 91.7%, 69.5%, and 65.6%, respectively ( P=0.268) . The 3-year OS rates were 91.7%, 71.4%, and 70.1%, respectively ( P=0.314) . Multivariate analysis revealed that advanced disease at allo-HSCT and TP53 mutations were independent risk factors for CIR, LFS, and OS. Conclusion:There was no significant difference in the prognosis of patients who underwent allo-HSCT among the MDS-AML, MDS/MPN-AML, and tAML groups. Advanced disease at transplantation and TP53 mutations were poor prognostic factors. ELN2022 risk stratification had limited value for predicting the prognosis of patients with sAML following allo-HSCT.

Objective: To explore the advantages and clinical efficacy of free chimeric perforator flap based on the descending branch of circumflex femoral artery applied to tongue reconstruction after advanced tongue cancer resection. Methods: From October 2013 to December 2018, 57 cases received tongue and oral base reconstruction surgeries using the descending branch of circumflex femoral artery chimeric perforator flap, including 39 males and 18 females, ranged from 20 to 76 years old. And all cases were with stage T3 and T4 tongue cancers, including 35 cases of squamous cell carcinoma, 7 cases of low differentiation cancer, 5 cases of oncosarcoma, and 10 cases of adenoid cystic carcinoma. The tongue was reconstructed by using perforator flap and muscle flap to fill the dead space at the oral floor. The artery anastomoses with the superior thyroid artery or facial artery in the receiving area, and the vein anastomoses with the internal jugular vein in the receiving area. The shape, function and local complications of the reconstructed tongue were observed after operation. Results: Of 57 cases, only one case had partial necrosis of flap, while other 56 cases with chimeric perforator flap survived. Postoperative gastric tube and tracheal cannula were removed in all patients, no cases with oral fistula. All donor sites were sutured in one stage. Postoperative radiotherapy was performed in 41 of the patients. All patients were followed up for 3 to 60 months (average of 20.7 months), with satisfactory esthetic and functional results in reconstructed tongues. Only linear scars were left in the donor areas of the legs, and no lower limb dysfunction was observed. Conclusions The descending branch of circumflex femoral artery chimeric perforator flap can used for repairing simultaneously the defects of both tongue and oral base. It is helpful to avoid the occurrence of oral fistula and to provide the reconstructed tongue with a good function. It is a good choice to use the descending branch of circumflex femoral artery chimeric perforator flap for tongue reconstruction after resection of advanced tongue cancer resection.
