Objective: To analyze the clinical characteristics and prognosis of adenovirus infection after allogeneic hematopoietic stem cell transplantation. Methods: A total of 26 patients with adenovirus infection admitted to the posttransplant ward of the First Affiliated Hospital of Soochow University from 2018 to 2022 were enrolled. Their data on baseline and clinical characteristics, treatment, and follow-up were analyzed. Results: The median patient age was 30 (22, 44) years. Twenty-two patients received related haploid stem cell transplantation, three received unrelated stem cell transplantation, and one received umbilical cord stem cell transplantation. Antithymocyte globulin was included in the conditioning regimen in 25 patients. The median time of adenovirus infection was +95 (+44, +152) days. The median peripheral blood lymphocyte count was 0.30 (0.11, 0.69) × 10(9)/L. Twelve patients had acute graft-versus-host disease. Twenty-four patients received antirejection therapies at diagnosis. Sixteen cases had combined infection with other pathogens with adenovirus infection. Eight cases were diagnosed as asymptomatic infection, and 18 were diagnosed as adenovirus disease, including pneumonia (38.89% ) , gastrointestinal disease (38.89% ) , encephalitis (33.33% ) , hepatitis (5.56% ) , and urinary tract inflammation (5.56% ) . The age of >30 years was a risk factor for adenovirus disease (P=0.03) . Eighteen patients received tapering of immunosuppression, and all 26 patients received at least one antiviral drug. Other treatments included high-dose gamma globulin and donor lymphocyte infusion. Adenovirus infection improved in 10 cases and progressed in 16 cases. The median follow-up time was 30 (7, 237) days. Twenty-two patients died. The all-cause mortality rate was (88.5±7.1) % , and the attributable mortality rate was 45.5% . There was no significant difference in the 100 d survival rate between asymptomatic infected patients and patients diagnosed with adenovirus disease (37.5% vs 22.2% , HR=1.83, 95% CI 0.66-5.04, P=0.24) . Conclusion: The age of >30 years was a risk factor for adenovirus disease. Mortality was high in patients with adenovirus infection after allogeneic hematopoietic stem cell transplantation.

Objective: To explore the surgical methods and clinical outcomes of severe angular kyphosis with the length of the spinal cord constant in the osteotomy area. Methods: Clinical data from 20 patients with severe angular kyphosis who underwent surgical treatment from January 2017 to December 2020 in the Department of Spinal Surgery,Hangzhou Xiaoshan District Hospital of Traditional Chinese Medicine were retrospectively analyzed. There were 11 males and 9 females, aged (28.5±8.9) years (range:17 to 46 years).There were 15 cases with congenital angular kyphosis,5 cases with tuberculous angular kyphosis.The angle of kyphosis was (107.1±12.9)° (range:93.2° to 131.4°).Frankel classification:2 cases with grade B,4 cases with grade C,3 cases with grade D.The kyphotic vertex is located at the T9 to T12 segments.Pedicle screws were placed in 3 or 4 adjacent segments at the proximal and distal kyphosis apex of the patients using a surgical navigation system.Piezosurgery combined with a grinding drill was used to complete the osteotomy in the apical vertebral region.Titanium mesh or artificial vertebral body was implanted,and the osteotomy surface was closed using this as the fulcrum to complete osteotomy.Spinal X-ray examination was performed before surgery,immediately after surgery and at the last follow-up,and sagittal and coronal Cobb angle,sagittal and coronary balance parameters,anterior vertebral height,posterior vertebral height,and spinal cord length were measured.Pulmonary function,visual analogue scale (VAS),and Oswestry's disability index (ODI) were collected and estimated before and after treatment.The analysis of variance of repeated measurement data was used for each evaluation index before and after treatment,and the t test was used for pairwise comparison. Results: All patients successfully completed surgery,with artificial vertebral body in 11 cases and double titanium mesh in 9 cases.The follow-up time was (28.2±2.3) months (range:26 to 31 months).Sagittal vertical axis improved from (46.9±13.7)mm(range:21.7 to 75.7 mm) before surgery to (10.7±5.5)mm (range:3.6 to 28.1 mm) after surgery,and (11.0±5.7)mm(range:3.6 to 29.3 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The mean kyphotic Cobb angle was corrected from (107.1±12.9) ° (range:93.2 ° to 131.4°) before surgery to (30.6±8.5) ° (range:20.0 ° to 47.8 °) after surgery (all P<0.01),and (32.1±8.7) ° (range:18.2 ° to 50.8°) at the last follow-up,the differences were statistically significant compared to before surgery(all P<0.01).The anterior vertebral height improved from (14.2±2.9)mm(range:11.04 to 23.6 mm) before surgery to (45.3±7.5)mm(range:29.4 to 56.5 mm) after surgery,and (44.3±6.8)mm(range:29.6 to 56.0 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The posterior vertebral height was improved from (51.8±5.3)mm (range:43.1 to 61.4 mm)before surgery to (57.6±4.7)mm (range:45.7 to 64.1 mm)after surgery,and (56.3±5.0) mm (range:49.7 to 68.5 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The spinal cord length of the osteotomy segment was (73.1±12.0)mm (range:56.8 to 98.4 mm) before surgery and (74.8±12.8)mm (range:53.5 to 100.2 mm) after surgery and (75.2±13.7)mm (range:53.9 to 102.4 mm) at the last follow-up,the difference was not statistically significant among them(F=0.144,P=0.866).The ODI and VAS scores improved significantly after surgery and at the last follow-up,and the differences were statistically significant (all P<0.01). Conclusion: The posterior vertebral column resection technique combined with titanium mesh or an artificial vertebral body implant for the treatment of severe angular kyphosis can significantly improve the kyphosis,neurological function,and life quality of patients without affecting the length of the spinal cord.

Cassiae Semen improves non-alcoholic fatty liver disease through autophagy-related pathway / 中草药·英文版

OBJECTIVE@#Cassiae Semen (CS, Juemingzi in Chinese) has been used for thousands of years in ancient Chinese history for relieving constipation, improving liver function as well as preventing myopia. Here we aimed to elucidate the anti-steatosis effect and underlying mechanism of CS against non-alcoholic fatty liver disease (NAFLD).@*METHODS@#High-performance liquid chromatography (HPLC) was used to identify the major components of CS water extract. Mice were fed with a high-fat and sugar-water (HFSW) diet to induce hepatic steatosis and then treated with CS. The anti-NAFLD effect was determined by measuring serum biomarkers and histopathology staining. Additionally, the effects of CS on cell viability and lipid metabolism in oleic acid and palmitic acid (OAPA)-treated HepG2 cells were measured. The expression of essential genes and proteins involved in lipid metabolism and autophagy signalings were measured to uncover the underlying mechanism.@*RESULTS@#Five compounds, including aurantio-obtusin, rubrofusarin gentiobioside, cassiaside C, emodin and rhein were simultaneously identified in CS extract. CS not only improved the diet-induced hepatic steatosis in vivo, as indicated by decreased number and size of lipid droplets, hepatic and serum triglycerides (TG) levels, but also markedly attenuated the OAPA-induced lipid accumulation in hepatocytes. These lipid-lowering effects induced by CS were largely dependent on the inhibition of fatty acid synthase (FASN) and the activation of autophagy-related signaling, including AMP-activated protein kinase (AMPK), light chain 3-II (LC3-II)/ LC3-1 and autophagy-related gene5 (ATG5).@*CONCLUSION@#Our study suggested that CS effectively protected liver steatosis via decreasing FASN-related fatty acid synthesis and activating AMPK-mediated autophagy, which might become a promising therapeutic strategy for relieving NAFLD.

Diagnosis and treatment of the short-arm type posterior semicircular canal BPPV / Diagnóstico e tratamento da VPPB de braço curto do canal semicircular posterior

Abstract Introduction The Epley maneuver is useful for the otoconia to return from the long arm of the posterior semicircular canal into the utricle. To move otoconia out of the posterior semicircular canal short arm and into the utricle, we need different maneuvers. Objective To diagnose the short-arm type BPPV of the posterior semicircular canal and treat them with bow-and-yaw maneuver. Methods 171 cases were diagnosed as BPPV of the posterior semicircular canal based on a positive Dix-Hallpike maneuver. We first attempted to treat patients with the bow-and-yaw maneuver and then performed the Dix-Hallpike maneuver again. If the repeated Dix-Hallpike maneuver gave negative results, we diagnosed the patient with the short-arm type of BPPV of the posterior semicircular canal and considered the patient to have been cured by the bow-and-yaw maneuver; otherwise, probably the long-arm type BPPV of the posterior semicircular canal existed and we treated the patient with the Epley maneuver. Results Approximately 40% of the cases were cured by the bow-and-yaw maneuver, giving negative results on repeated Dix-Hallpike maneuvers, and were diagnosed with short-arm lithiasis. Conclusion The short-arm type posterior semicircular canal BPPV can be diagnosed and treated in a convenient and comfortable manner.

Primeiro tentamos tratar os pacientes com a manobra de incline and balance e, em seguida, executamos a manobra de Dix-Hallpike novamente. Se a repetição da manobra de Dix-Hallpike desse resultados negativos, diagnosticávamos o paciente como VPPB do canal semicircular posterior do tipo braço curto e considerávamos que ele ou ela havia sido curado pela manobra de incline and balance; caso contrário, provavelmente o paciente apresentava VPPB do canal semicircular posterior do tipo braço longo e tratávamos o paciente com a manobra de Epley. Resultados Aproximadamente 40% dos casos foram curados pela manobra de incline and balance, com resultados negativos nas manobras de Dix-Hallpike repetidas, e foram diagnosticados com litíase de braço curto. Conclusão A VPPB de canal semicircular posterior do tipo braço curto pode ser diagnosticada e tratada de maneira conveniente e confortável.

Analysis of therapeutic effect and influencing factors of radiofrequency ablation for colorectal cancer liver metastases / 中华放射学杂志

Objective:To explore the efficacy and influencing factors of radiofrequency ablation (RFA) in the treatment of colorectal cancer liver metastases (CRLM).Methods:The clinical and imaging data of 281 patients (477 intrahepatic metastatic tumors) who received percutaneous RFA treatment in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine from December 2009 to December 2020 were retrospectively analyzed. Factors that may affect the efficacy of RFA were recorded, including carcinoembryonic antigen (CEA), differentiation, extrahepatic metastasis, tumor location and size, complications and other information. Patients were followed up through hospital admissions, telephone, etc. The primary endpoints were overall survival (OS) and local tumor progression-free survival (LTPFS). Univariate and multivariate logistic regression models were used to identify predictors of residual tumor. Univariate and multivariate Cox proportional hazards regression were used to identify the influencing factors of LTPFS and OS. The median LTPFS and OS were estimated by the Kaplan-Meier curve and compared by the log-rank test.Results:After RFA, 68 (14.3%) tumor residues were observed. Multivariate logistic regression showed that the risk factors for residual tumor were size ≥20 mm, high-risk and perivascular location, and minimal ablative margin<5 mm. During the follow-up period, the main complication rate was 4.3% (12/281) and the fatality rate was 31.3% (88/281). At the same time, local tumor progression was found in 167 (35.0%) lesions post-RFA. The median time of LTPFS and OS estimated by the Kaplan Meier method were 35.0 (95%CI 26.53-43.48) and 44.0 (95%CI 29.70-58.30) months, respectively. The cumulative proportion of LTPFS and OS were 37.2% and 40.4% respectively in the 5th year. Multivariate Cox proportional hazard regression showed that CEA≥30 ng/ml, tumor size ≥20 mm, and minimal ablative margin<5 mm were risk factors for LTPFS; extrahepatic metastasis, tumor burden>30 mm, and lesion with minimal ablative margin<5 mm were independent risk factors for OS; re-intervention was an independent protective factor for OS.Conclusions:Adequate ablative margin and less tumor burden were beneficial to local tumor control and long-term survival of patients in the RFA treatment; the existence of extrahepatic metastasis was an important risk factor for OS, and re-interventional therapy was beneficial to extend OS.

More than 80% of the students in the experimental group regarded that the combined teaching method was helpful to promote the interaction between teachers and students, master relevant knowledge, and improve learning interest and learning efficiency. Conclusion:This combined teaching method can enhance students' clinical thinking ability, learning enthusiasm and efficiency, and finally effectively improve the effect of clerkship.

The relevance of EZH2 polymorphism to breast cancer risk in Chinese females: results from a multicenter case-control study / 中华普通外科杂志

Objective:To investigate the relationship between single nucleotide polymorphism (SNPs) of Zeste homolog enhancer 2 (EZH2) gene and the risk of breast cancer.Methods:Recruiting 1 039 breast cancer patients and 1 040 controls at 22 referral hospitals nationwide in China, the genotype distribution of 3 SNPs loci of EZH2 genes was observed to detect the correlation between different genotypes and the risk of breast cancer genotypes EZH2 expression in breast cancer tissues and its correlation with patient prognosis were analyzed using breast cancer data from the database.Results:EZH2 rs6464926 CC genotype was compared with TT genotype (TT vs. CC: OR=1.362, 95% CI: 1.063-1.746, P=0.015) and dominant model (TC+TT vs .CC: OR=1.22, 95% CI: 1.004-1.483, P=0.045) .In women with BMI ≥24 kg/m 2, the TC genotype ( P=0.050), TT genotype ( P=0.025) and dominant model (TC+TT, P=0.021) of rs6464926 locus were significantly different from CC genotype in cancer risk. rs6464926 was correlated with EZH2 gene expression ( P=6.89E-47). EZH2 gene is highly expressed in breast cancer tissues, and patients with high expression were associated with shorter OS ( HR=1.27, P=0.013), DMFS ( HR=1.37, P<0.01), and RFS ( HR=1.44, P<0.01). Conclusions:The polymorphism rs6464926 of EZH2 gene is associated with breast cancer susceptibility in Chinese women. rs6464926 might regulate breast cancer risk and prognosis by changing EZH2 expression.

Ziyuglycoside II inhibits the growth of digestive system cancer cells through multiple mechanisms / 中国天然药物

Digestive system cancers, including liver, gastric, colon, esophageal and pancreatic cancers, are the leading cause of cancers with high morbidity and mortality, and the question of their clinical treatment is still open. Previous studies have indicated that Ziyuglycoside II (ZYG II), the major bioactive ingredient extract from Sanguisorba officinalis L., significantly inhibits the growth of various cancer cells. However, the selective anti-tumor effects of ZYG II against digestive system cancers are not systemically investigated. In this study, we reported the anti-cancer effect of ZYG II on esophageal cancer cells (OE21), cholangiocarcinoma cells (HuCCT1), gastric cancer cells (BGC-823), liver cancer cells (HepG2), human colonic cancer cells (HCT116), and pancreatic cancer cells (PANC-1). We also found that ZYG II induced cell cycle arrest, oxidative stress and mitochondrial apoptosis. Network pharmacology analysis suggested that UBC, EGFR and IKBKG are predicted targets of ZYG II. EGFR signaling was suggested as the critical pathway underlying the anti-cancer effects of ZYG II and both docking simulation and western blot analysis demonstrated that ZYG II was a potential EGFR inhibitor. Furthermore, our results showed synergistic inhibitory effects of ZYG II and chemotherapy 5-FU on the growth of cancer cells. In summary, ZYG II are effective anti-tumor agents against digestive cancers. Further systemic evaluation of the anti-cancer activities in vitro and in vivo and characterization of underlying mechanism will promote the development of novel supplementary therapeutic strategies based on ZYG II for the treatment of digestive system cancers.

Mechanisms exploration of Angelicae Sinensis Radix and Ligusticum Chuanxiong Rhizoma herb-pair for liver fibrosis prevention based on network pharmacology and experimental pharmacologylogy / 中国天然药物

Angelicae Sinensis Radix (Danggui) and Ligusticum Chuanxiong Rhizoma (Chuan Xiong) herb-pair (DC) have been frequently used in Traditional Chinese medicine (TCM) prescriptions for hundreds of years to prevent vascular diseases and alleviate pain. However, the mechanism of DC herb-pair in the prevention of liver fibrosis development was still unclear. In the present study, the effects and mechanisms of DC herb-pair on liver fibrosis were examined using network pharmacology and mouse fibrotic model. Based on the network pharmacological analysis of 13 bioactive ingredients found in DC, a total of 46 targets and 71 pathways related to anti-fibrosis effects were obtained, which was associated with mitogen-activated protein kinase (MAPK) signal pathway, hepatic inflammation and fibrotic response. Furthermore, this hypothesis was verified using carbon tetrachloride (CCl

Analysis of antibiotic usage for viral community-acquired pneumonia in adults / 医学前沿

The rationale for the antibiotic treatment of viral community-acquired pneumonia (CAP) in adults was analyzed to develop a clinical reference standard for this condition. Clinical data from 166 patients diagnosed with viral pneumonia across 14 hospitals in Beijing from November 2010 to December 2017 were collected. The indications for medications were evaluated, and the rationale for the use of antibiotics was analyzed. A total of 163 (98.3%) patients with viral pneumonia were treated with antibiotics. A combination of C-reactive protein (CRP) and procalcitonin (PCT) was used as markers to analyze the possible indications for antibiotic use. With threshold levels set at 0.25 µg/L for PCT and 20 mg/L for CRP, the rate of unreasonable use of antibiotics was 55.2%. By contrast, at a CRP level threshold of 60 mg/L, the rate of antibiotic misuse was 77.3%. A total of 39 of the 163 (23.9%) patients did not meet the guidelines for drug selection for viral CAP in adults. The unreasonable use of antibacterial drugs for the treatment of viral CAP in adults is a serious concern. Clinicians must reduce the unnecessary use of antibiotics.

Roles of TSA upregulation miR-4298 targeting inhibition of PADI4 expression in inducing U251 cells apoptosis / 国际肿瘤学杂志

Objective:To investigate the mechanism of microRNA-4298 (miR-4298) targeting inhibition of peptidylarginine deiminase 4 (PADI4) expression in U251 cells apoptosis induced by histone deacetylase inhibitor trichostatin A (TSA).Methods:The experiment was divided into TSA group (0.2 μmol/L TSA) and contral group. CCK8 method was used to detect the effect of TSA on the proliferation of U251 cells. Flow cytometry was used to detect the apoptosis level of U251 cells after drug action. Reverse transcription PCR and Western blotting experiments were used to determine the changes of PADI4 gene and protein expression after miR-4298 interference. Luciferase assay was used to determine the effects of miR-4298 on targeted binding and luciferase activity in the 3′UTR region of PADI4. U251 cells were transfected with PADI4 to observe the rescue effect of miR-4298 on apoptosis. Each experiment was divided into 3 groups, NC group, miR-4298 mimic group, TSA+ miR-4298 mimic group and NC group, miR-4298 inhibitor group, TSA+ miR-4298 inhibitor group.Results:U251 cells were treated with 0.2 μmol/L TSA for 4 days, the Absorbancy ( A) values of the control group was 1.168±0.148, which was higher than those of the TSA group (0.737±0.007), with statistically significant difference ( t=4.948, P=0.008). Compared with the control group, after treatment with 0.2 μmol/L TSA for 48 h, U251 cells showed obvious apoptosis (27.62%±3.49% vs. 4.99%±0.13%, t=11.190, P<0.001). Compared with those before the drug treatment, the PADI4 gene expression (0.386±0.020 vs. 0.903±0.021) and protein expression (0.276±0.041 vs. 0.777±0.031) after TSA treatment for 48 h both were decreased, with statistically significant differences ( t=30.400, P<0.001; t=16.770, P<0.001). The expression of miR-4298 during the process of TSA-induced U251 cell apoptosis increased (2.573±0.289 vs. 1.003±0.136; t=8.487, P=0.001). There was a negative correlation between the miR-4298 expression and PADI4 expression ( r=-0.877, P=0.002). Luciferase experiment confirmed that miR-4298 has targeted binding and luciferase inhibitory effects on the 3′UTR region of wild-type PADI4. Compared with NC group (0.920±0.026), the relative expression levels of PADI4 gene of miR-4298 mimic group (0.413±0.049) and TSA+ miR-4298 mimic group (0.213±0.035) were decreased, with statistically significant differences (all P<0.001). The PADI4 protein expression level change was consistent with the gene change trend. Compared with NC group (3.78%±0.68%), the apoptosis levels of miR-4298 mimic group (7.96%±1.10%) and TSA+ miR-4298 mimic group (13.74%±1.26%) were increased, with statistically significant differences ( P=0.005; P<0.001). Compared with NC group (0.183±0.025), the PADI4 gene expression of miR-4298 inhibitor group (0.483±0.032) and TSA+ miR-4298 inhibitor group (0.386±0.025) were increased, with statistically significant differences ( P<0.001; P=0.015). The PADI4 protein expression level change was consistent with the gene change trend. Compared with NC group (4.96%±0.59%), the apoptosis levels of miR-4298 inhibitor group (23.83%±2.20%) and TSA+ miR-4298 inhibitor group (9.55%±1.49%) were increased, with statistically significant differences (all P<0.001). In the rescue experiment, the expression level of PADI4 in miR-4298 mimic group was significantly increased ( P<0.001), while the expression level of PADI4 in miR-4298 mimic+ PADI4 group was relatively reversed ( P=0.002). Conclusion:miR-4298 can participate in the process of U251 cell apoptosis by targeting the expression of PADI4 gene, and miR-4298 may be the target of targeted intervention therapy for glioma.

Objective:To explore the effects of mirror therapy on upper limb motor function recovery and corticospinal tract remodeling after stroke. Methods:From March, 2017 to March, 2019, 42 subcortical stroke patients with upper limb dysfunction from Shanghai Fifth People's Hospital were randomly divided into control group (n = 21) and observation group (n = 21). Both groups received routine rehabiliation, while the observation group received mirror therapy additionally, for twelve weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), and scanned with diffusion tensor imaging (DTI) before and after treatment. The fractional anisotropy (FA) in posterior limb of internal capsule (PLIC) was obtained. Results:The scores of FMA-UE improved in both groups after treatment (t > 9.560, P < 0.001), and improved more in the observation group than in the control group (t > 2.634, P < 0.05). FA decreased significantly in the affected-lateral PLIC compared with that in the unaffected-lateral PLIC in both groups (t > 11.368, P < 0.001). FA in the affected side increased significantly after treatment in the observation group (t = 2.385, P < 0.05), while there was no significant difference in the control group (t = -0.596, P > 0.05). FA increased more significantly in the observation group than in the control group (t = 2.306, P < 0.05). Conclusion:Mirror therapy can promote the recovery of motor function of upper limb and the corticospinal tract remodeling in stroke patients.

The improvement of symptoms before operation, test period and last follow-up were compared.Results:The urgency score was 2 (1, 3), the 24-hour micturition frequency was 17.00 (15.00, 22.75), the frequency of nocturia was 5.5 (4.0, 7.0), the single urine volume was 87.50 (70.25, 110.00) ml, the VAS score was 4.0 (3.0, 6.0) and the O′Leary-Sant score was 20.00 (17.00, 23.00) in 28 patients during the test period, which were significantly improved compared with those before operation ( P < 0.05). There was no significant difference in the single maximum urine volume of 135.0 (102.5, 160.0) ml between the two groups ( P > 0.05). 28 patients received SNM Ⅱ permanent stimulator implantation. The median follow-up time was 29.5 (21.25, 61.75) months. Among the 28 patients, 3 patients underwent cystectomy and ileal conduit after removal of the complete SNM system due to the unsatisfied results. Twenty-five cases (89.3%) were still treated with SNM. Among them, 6 cases accepted combinative therapy of oral medicine (antihistamines, sodium pentose polysulfate, hormones, immunosuppressants, etc.). Two cases accepted combinative therapy of intravesical instillation, including heparin in one case and sodium hyaluronate in the other one. Three cases accepted combinative therapy of botulinum toxin injection.One case accepted combinative therapy of bladder augmentation. Two cases accepted combinative therapy of traditional Chinese medicine (TCM). One case accepted combinative therapy of oral medicine and TCM. The remaining 10 cases didn't accept any treatment. Among them, 3 cases were still treated with SNM even though they were not satisfied with the effect, including 1 case due to electrode displacement. At the last follow-up of 25 patients, the urgency score was 2 (1, 3), the 24-hour micturition frequency was 16.50 (13.00, 19.75), the frequency of nocturia was 5.5 (4.0, 9.0), the single urine volume was 105.0 (72.5, 120.0) ml, the VAS score was 4.5 (3.0, 6.0) and the O'Leary Sant score was 16.00 (14.00, 22.50), which were significantly improved compared with those before operation ( P < 0.05), but no difference with those during test period ( P>0.05). There was no significant difference in the single maximum urine volume of 125.0 (102.5, 150.0) ml at the last follow-up compared with preoperative and test period ( P>0.05). Conclusions:As a treatment option for refractory IC / BPS, SNM can improve the symptoms of most patients and maintain good long-term efficacy combined with other.

The similarities and differences between air-charged catheters and water-filled catheters in the application of pressure-flow study / 中华泌尿外科杂志

Objective:We compare the consistency, similarities and differences of operating procedures, data and conclusions of air-charged catheters(ACC) and water-filled catheters(WFC), as simultaneously using ACC and WFC in pressure-flow study(PFS).Methods:This study was a prospective, synchronously controlled study, including eligible patients who underwent PFS in the Department of Urology, Beijing Chaoyang Hospital from January 2021 to March 2021. Inclusion criteria: ① Patients need PFS for lower urinary tract symptoms like frequency of urination, urgent urination, urinary incontinence and dysuria; ② Age over 18 years old. Exclusion criteria: ① Unable to complete or cooperate during the urodynamic test; ② Patients with severe urethral stricture or acute stage urinary tract infection; ③ Pregnant women. The bladder pressure was measured continuously by using a 7FDR T-DOC ?AC three-chamber bladder pressure tube, which linked to ACC sensor and improved WFC pressure conduction module. At the same time, 7FA T-DOC ?AC single-lumen rectal pressure tube and 7F Labori-CAT411 double-lumen water sac abdominal pressure tube was used to measure the ACC and WFC rectum pressure, respectively. We recorded the Pdet, Pves and Pabd measured by ACC and WFC, at the point of initial sitting position, bladder filling at 100 ml, 150 ml, 200 ml, cough, Q max, maximum Pdet and the end of urination, and compared the mean values, differences, and consistencies of our data. Result:A total of 63 patients (26 female, 37 male) were included in this study, with an average age of 59.19 years (25-86 years old). During bladder filling phase, the mean values of Pves measured by ACC and WFC were 30.78/24.67cmH 2O (initial sitting position), 29.79/25.13cmH 2O (100 ml), 30.87/25.90cmH 2O (150 ml) and 30.95/26.17cmH 2O(200 ml), respectively, the mean value of Pabd were 30.03/24.17cmH 2O (initial sitting position), 28.81/21.78cmH 2O (100ml), 28.89/21.38cmH 2O (150ml), 28.44/21.60cmH 2O (200ml), respectively, and were significantly different at each sampling point ( P<0.01). During urination period, no significant differences were found in data( P>0.05), and the data measured with ACC and WFC system have good consistency. There were significant differences in Pves(mean 57.30/49.95 cmH 2O, respectively) and Pdet(mean 54.21/43.10 cmH 2O, respectively) between ACC and WFC in cough ( P<0.01), but there was a strong linear correlation between these data between two systems(R 2=0.792 in Pves and 0.756 in Pabd). Bland-Altman analysis showed that detrusor pressure at the maximum urine flow rate maintained good consistency between ACC and WFC, which 95% CI was -13.9 cmH 2O to 15.8 cmH 2O. Conclusions:In PFS, although the ACC measurement values (Pves and Pabd) during the filling phase are higher than those WFC readings, but the absolute measurement difference is small, so there is no practical meaning in clinical practice. There was no significant difference in detrusor pressure measured during voiding phase, which indicated that the urodynamic judgment and clinical conclusions of the two systems are highly consistent in judgment of the detrusor contractility and the bladder outlet obstruction.

Advances in small molecule inhibitors of ACK1 / 药学学报

ACK1 (activated Cdc42-associated kinase) is a non-receptor tyrosine kinase, originally identified by its binding to the GTP-binding small GTPase Cdc42. It is widely expressed in human tissues and activated by various extracellular growth factors such as EGF, PDGF and TGF-β. The activated ACK1 mediates the signaling cascade by interacting with downstream effectors followed by their phosphorylation. In recent years, researchers have investigated the biological functions of ACK1 and its roles in cancer research. The gene amplification and overexpression of ACK1 is associated with a poor prognosis and metastasis in a variety of cancers including lung, ovarian and prostate cancers. Therefore, the development of small molecule inhibitors of ACK1 provides promising opportunities for cancer-targeted therapy. In this review, we briefly describe recent advances in understanding the activation and biological function of ACK1 and introduce its novel inhibitors with potential therapeutic activities in preclinical studies.

Effect and Safety of Hydroxysafflor Yellow A for Injection in Patients with Acute Ischemic Stroke of Blood Stasis Syndrome: A Phase II, Multicenter, Randomized, Double-Blind, Multiple-Dose, Active-Controlled Clinical Trial / 中国结合医学杂志

OBJECTIVE@#To assess the effect and safety of Hydroxysafflor Yellow A for Injection (HSYAI) in treating patients with acute ischemic stroke (AIS) and blood stasis syndrome (BSS).@*METHODS@#A multicenter, randomized, double-blind, multiple-dose, active-controlled phase II trial was conducted at 9 centers in China from July 2013 to September 2015. Patients with moderate or severe AIS and BSS were randomly assigned to low-, medium-, high-dose HSYAI groups (25, 50 and 70 mg/d HSYAI by intravenous infusion, respectively), and a control group (Dengzhan Xixin Injection (, DZXXI) 30 mL/d by intravenous infusion), for 14 consecutive days. The primary outcome was the Modified Rankin Scale (mRS) score ⩽1 at days 90 after treatment. The secondary outcomes included the National Institute of Health Stroke Scale (NIHSS) score ⩽1, Barthel Index (BI) score ⩾95, and BSS score reduced ⩾30% from baseline at days 14, 30, 60, and 90 after treatment. The safety outcomes included any adverse events during 90 days after treatment.@*RESULTS@#Of the 266 patients included in the effectiveness analysis, 66, 67, 65 and 68 cases were in the low-, medium-, and high-dose HSYAI and control groups, respectively. The proportions of patients in the medium- and high-dose HSYAI groups with mRS score ⩽1 at days 90 after treatment were significantly larger than the control group (P0.05).@*CONCLUSIONS@#HSYAI was safe and well-tolerated at all doses for treating AIS patients with BSS. The medium (50 mg/d) or high dose (75 mg/d) might be the optimal dose for a phase III trial. (Registration No. ChiCTR-2000029608).

Mental health status of medical staff in the epidemic period of coronavirus disease 2019 / 中南大学学报(医学版)

OBJECTIVES@#To explore the psychological status of medical staff in the epidemic period of coronavirus disease 2019 (COVID-19), and to analyze its influential factors.@*METHODS@#A total of 373 medical staff from Xiangya Hospital and the Second Xiangya Hospital of Central South University were enrolled for this study. The General Sociological Data Questionnaire, Symptom Check-List 90 (SCL-90), and self-designed public opinion response questionnaire were used to assess general sociological data, mental health scores, and ability to respond to COVID-19 related public opinion information of medical staff. The mental health scores of medical staff with different general sociological data and public opinion information coping abilities were compared. Influential factors of mental health were analyzed.@*RESULTS@#The average score of 10 factors in SCL-90 of 373 medical staff was less than 2 points. 14.21% medical staff had one or more factor scores more than two points, including 11.26% with terror symptoms, 7.77% with compulsive symptoms, and 5.63% with anxiety. The main sources of COVID-19 information for medical staff included WeChat, microblog, Jinri toutiao, TV and radio. 66.22% medical staff regularly verified information about COVID-19 through official websites or formal channels. A great deal of COVID-19 information in WeChat could make medical staff nervous (34.05%), anxious (30.29%), and insecure (29.22%). 68.63% medical staff sometimes were worried about getting infected because they knew information about COVID-19. Different departments of medical staff, getting cough or having a fever recently, and the degree of fear of infection had an impact on the SCL-90 score of medical staff, the differences were all statistically significant (all <0.05). Stepwise regression analysis showed that the impact of COVID-19 information on their life in WeChat, getting cough or having a fever recently, insomnia-early caused by COVID-19 information in WeChat, different departments, and the degree of fear of infection COVID-19 were the influential factors for the mental health of medical staff (all <0.05).@*CONCLUSIONS@#During the epidemic of COVID-19, medical staff suffered from psychological problems to various degrees. It is necessary to establish a psychological assistance platform and guide the direction of public opinion correctly to promote the mental health of medical staff.
