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 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.

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.

“Omics” is a integral thought, which can provide a non-bias method, identify the biochemical pathways of the diseases, and ultimately determine the target for future research. 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 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.
