Objective:To compare the clinical efficacy of transperitoneal robot assisted laparoscopic radical prostatectomy (RARP) versus extraperitoneal single port RARP.Methods:A retrospective analysis was perfoumed on 142 cases of RARP from July 2019 to June 2020 in Robotic Minimally Invasive Center of Sichuan Provincial People's Hospital, including 82 cases(Group A) , aged 70.0(65.6-78.0), undergoing transperitoneal RARP and 60 cases(Group B), aged 68.2 years old(60.1-79.2), undergoing extraperitoneal single port RARP. For group A, PSA was 12.9(5.6-64.0) ng/ml, with 26 cases of less than 10 ng/ml(31.7%), 40 cases of 10-20 ng/ml(48.8%), and 16 cases of more than 20 ng/ml(19.5%), the Gleason score was 7.2(6.0-10.0), with 14 cases(17.1%) of ≤6, 56 cases(68.3%) of 7, and 12 cases(14.6%) of ≥8, and the prostate volume was 61.3(29.0-112.0) ml. There were 49 cases with BMI≤25 kg/m 2, accounting for 59.8%, and 33 cases with BMI>25 kg/m 2, accounting for 40.2%. There were 17 cases(20.7%) of T 1, 44 cases(53.7%) of T 2 and 21 cases(25.6%) of T 3. The proportion of lymph node dissection was 17.1%, and 4 cases(4.9%)had a history of operation. For group B, the PSA was 12.2(1.0-42.6)ng/ml, with 20 cases (33.3%) of <10 ng/ml, 31 cases(51.7%)of 10-20 ng/ml, and 9 cases (15%) of >20 ng/ml. Gleason score was 7.1(6.0-9.0), with 12 cases (20.0%) of ≤6, 42 cases (70.0%) of 7, and 6 cases (10.0%)of ≥8. Prostate volume was 42.4(31.2-72.8)ml on average. There were 37 cases (61.7%) with BMI≤25 kg/m 2, and 23 cases (38.3%)with BMI >25 kg/m 2 . There were 17 cases(28.3%)of T 1, 32 cases(53.3%)of T 2 and 11 cases(18.3%)of T 3.The proportion of lymph node dissection was 11.7% and 4 cases (6.7%) had a history of operation.There was no statistically significant difference in term of age, PSA level, Gleason score, BMI, clinical stage, proportion of lymph node dissection or history of operation between the two groups( P>0.05), but there was statistically significant difference for prostate volume( P<0.05). All operations were performed by the same operator. Four different ways of bladder neck and urethral dissociation was selected according to the intraoperative conditions in Group A, include VIP style, T-shape incision style, VIP plus T-shape incision style or the style along the lateral side of the bladder neck. Small and single anterograde incision stripping of bladder neck was routinely performed in the Group B. Postoperative follow-up was performed to compare the operation time, intraoperative blood loss, bladder neck and urethral anastomosis time, postoperative hospital stay, postoperative exhaust time, postoperative complications, positive rate of surgical margin, indwelling time of urinary catheter, urinary continence satisfaction rate of immediately after operation, 3 months and 6 months after operation, wound healing and aesthetics. Results:All of the operations were successfully completed under robot-assisted laparoscopy, and there was no conversion to open surgery. The operation time was 56.0(45.0-112.0) min in the Group A and 65.4(55.5-96.8) min in the Group B, and there was no statistically significant difference( P>0.05). The intraoperative blood loss was 76.2(30.0-120.5) ml and 55.6(45.5-114.6) ml, respectively, and the difference was not statistically significant( P>0.05). The time of bladder neck urethral anastomosis was 18.9(12.6-25.6) min and 16.2(10.7-19.3) min, respectively, and the difference was not statistically significant( P>0.05). The postoperative hospital stay days were 9.3(8.0-16.0) d and 8.4(7.0-13.0) d, respectively, and the difference was not statistically significant( P>0.05). The postoperative exhaust time was 1.3(0.7-3.0) d and 3.4(2.0-7.0) d, respectively, and the difference was statistically significant( P<0.05). There was 1 case of anastomotic fistula with ureteral injury in Group A, and no serious complication in Group B, and the difference was not statistically significant( P>0.05). The number of positive surgical margin in the two groups was 13(15.9%)and 9(15.0%)respectively, and the difference was not statistically significant( P>0.05). The indwelling time of urinary catheter after operation was 9(7-21) d and 6(4-8) d, respectively, and the difference was statistically significant( P<0.05). The number of patients with satisfactory urinary continence immediately after surgery, 3 months and 6 months after surgery in the two groups were 8(9.8%), 51(62.2%), 62(75.6%) and 17(28.3%), 43(71.7%) and 54(90.0%), respectively. The differences were statistically significant( P<0.05). The total incision lengths in the two groups were 12.1(10.4-13.4) cm and 5.6(5.0-6.0) cm, respectively, and the difference was statistically significant( P<0.05). Conclusions:The extraperitoneal single port RARP is safe and feasible, and the postoperative effect is similar to that of transperitoneal RARP. It has the advantages of shorter recovery time, higher urinary continence satisfaction rate, neater and more beautiful incision. The long-term therapeutic effect needs further confirming by prospective study.

The correlation between hearing loss (HL) and physical performance in patients receiving maintenance hemodialysis (MHD) remains poorly investigated. This study explored the association between HL and physical performance in patients on MHD. Methods: This multicenter cross-sectional study was conducted between July 2020 and April 2021 in seven hemodialysis centers in Shanghai and Suzhou, China. The hearing assessment was performed using pure-tone average (PTA). Physical performance was assessed using the Timed Up and Go Test (TUGT), handgrip strength, and gait speed. Results: Finally, 838 adult patients (male, 516 [61.6%]; 61.2 ± 2.6 years) were enrolled. Among them, 423 (50.5%) had mild to profound HL (male, 48.6% and female, 53.4%). Patients with HL had poorer physical performance than patients without HL (p < 0.001). TUGT was positively correlated with PTA (r = 0.265, p < 0.001), while handgrip strength and gait speed were negatively correlated with PTA (r = –0.356, p < 0.001 and r = –0.342, p < 0.001, respectively). Physical performance in patients aged <60 years showed significant dose-response relationships with HL. After adjusting for confounders, the odds ratios (95% confidence intervals) for HL across the TUGT quartiles (lowest to highest) were 1.00 (reference), 1.15 (0.73–1.81), 1.69 (1.07–2.70), and 2.87 (1.69–4.88) (p for trend = 0.005). Conclusion: Lower prevalence of HL was associated with a faster TUGT and a stronger handgrip strength in patients on MHD.

Objetive： To investigate the mechanism of antidepressant effect of verbascoside based on high-throughput sequencing technology （RNA-Seq），and to explore the possible targets and signaling pathways. MethodsForty C57BL/6 mice were randomly divided into control group，model group，fluoxetine group and verbascoside group，10 mice in each group. Except for the control group，all the other three groups were constructed with chronic unpredictable mild stimulation （CUMS） combined with solitary feeding for four weeks. Control group，fluoxetine group and verbascoside group were administered by gavage once daily for three weeks during the second week of modeling. The mice were assessed by sugar-water preference test，forced swimming test，open field test，elevated cross maze test，and water maze test. Enzyme linked immunosorbent assay（ELISA） was performed to detect the levels of major neurotransmitters and inflammatory factors in mice serum，and mRNA high-throughput sequencing was performed in the nucleus accumben and colon to screen differentially expressed genes and perform pathway enrichment analysis. Real-time polymerase chain reaction（Real-time PCR） was used to detect the mRNA expression of Gad，Slc32a1（VGAT） and brain-derived neurotrophic factor (BDNF） in nucleus accumbens. ResultCompared with the control group，the anxiety and depression-like behaviors in the model group increased，while the learning and memory ability decreased significantly. The content of neurotransmitter in serum decreased significantly. The content of pro-inflammatory factors increased significantly. The mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens decreased significantly，while that of BDNF increased significantly. Compared with the model group，the anxiety and depression-like behavior of mice in verbascoside group was significantly relieved. The neurotransmitter content increased significantly，and the pro-inflammatory factors decreased significantly. The mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens increased significantly，while that of BDNF decreased significantly.A total of 48 differentially expressed genes in nucleus accumbens and 43 differentially expressed genes in colon were screened by high-throughput sequencing. Differential genes in nucleus accumbens mainly focus on neuroactive ligand-receptor interaction， γ-aminobutyric acid（GABA）ergic synapse，synaptic vesicle cycle and other pathways. Colonic differential genes are mainly concentrated in GABAergic synapses，synaptic vesicle circulation，cyclic adenosine monophosphate（cAMP） signal pathway and other signal pathways. Compared with the control group，the mRNA expression of Gad and Slc32a1（VGAT） in nucleus accumbens of model group decreased significantly，while the mRNA expression of BDNF increased significantly. ConclusionVerbascoside has significant antidepressant effects. Its antidepressant effect may be related to the increase of monoamine neurotransmitters，the decrease of pro-inflammatory factors and the restoration of neurotransmitter homeostasis by increasing GABA，and it mainly acts through the signaling pathways such as neuroactive ligand-receptor interaction，GABAergic synapses，synaptic vesicle cycle and cAMP signaling pathway.

ObjectiveThis study aimed to understand the epidemiological characteristics of hand-foot-mouth disease （HFMD） in Minhang District， Shanghai from 2009 to 2020， and provide a scientific basis for the prevention and control of HFMD. MethodsThe case information of HFMD was collected from the National Notifiable Infectious Diseases Reporting System of Chinese Center for Disease Control and Prevention. We used descriptive epidemiological methods to analyze the population characteristics， temporal and spatial distribution of HFMD， the pathogen composition of the case and its changing trend. ResultsFrom 2009 to 2020， a total of 66，198 cases of HFMD were reported in Minhang District， Shanghai， including 377 severe cases （severe case rate 0.57%） and 3 deaths （severs case fatality rate 0.80%）. There were more cases of HFMD in boys than in girls （1.5∶1）. HFMD patients aged under 5 years predominated， accounting for 88.91% of all cases. Majority of the cases （91.42%） were in scattered children （55.80%） and children in kindergartens （35.62%）. The incidence showed a cyclical trend， with low incidence years and high incidence years appearing alternately. The peak period was from April to July， and sometimes there were small peaks during October to December. A total of 12 years time-space scanning analysis revealed 3 clusters. The cluster centers were located in Wujing Town， Huacao Town and Xinzhuang Town， respectively. The proportion of EV71 in common cases was generally decreasing， and reduced to zero in 2019. The proportion of CoxA6 had increased year by year， and reached 75.00% in 2020. CoxA6 became the dominant pathogen in recent years. The number of severe cases had decreased year by year since 2010， and the dominant pathogen was EV71 （90.03% on average） in severe cases. ConclusionThe incidence of HFMD in Minhang District of Shanghai has a downward trend from 2014. The dominant pathogen changes from EV71 to CoxA6， and the dominant pathogen in severe cases is EV71. The discovered temporal and spatial clustering pattern is helpful for in-depth understanding of the distribution and epidemic trend of HFMD in Minhang District， and provides a scientific basis for epidemic prevention and control.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.
