Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters,such as R.E.N.A.L.,PADUA,C-Index,which are used to guide the clinical selection of surgical modalities,and predict perioperative complications and prognosis. In this paper,various scoring systems are grouped into three major categories according to their functions:prediction of surgical complexity,prediction of complications,and prediction of prognosis. The contents,characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists,enhance their surgical decision-making ability,and improve the clinical outcomes.

Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

Objective:To identify the genetic mutation of coagulation factor Ⅶ(F7)gene in a pedigree with coagulation factor Ⅶ(FⅦ)deficiency and explore the molecular pathogenesis.Methods:The prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),D-dimer(DD),fibrin degradation products(FDP)and coagulation factor Ⅶ activity(FⅧ:C)of the proband and her family members were detected by Sysmex-CS5100 analyzer.All exons and exon-intron boundaries of the F7 gene were amplified by PCR followed by direct sequencing.The detected mutation was confirmed by reverse sequencing.The ClustalW software was used to analyze the conservatism of the mutant site.Pathogenicity of the mutation was assessed with Mutation Taster and PolyPhen-2 online bioinformatics software.Structure of the mutant protein was analyzed using Swiss-PdbViewer software.Results:The results of routine coagulation tests showed that PT of the proband was markedly extended to 42.5 s,and her FⅦ:C significantly reduced to 2%.The FⅦ:C of her grandmother,mother and sister had slightly reduced to 49%,51%,and 42%,respectively.These coagulant parameters of her father were within the normal range.Genetic analysis reveled a heterozygous G>A change at cDNA 646 in exon 6 of F7 gene in the proband,resulting in a replacement of glycine at 156 of FⅦ catalytic region with serine(p.Gly156Ser).The sequencing results of other exons and exon-intron boundaries of her F7 gene were normal.The proband's grandmother,mother and sister were all the carriers of this missense mutation except her father.Bioinformatics analysis showed that the p.Gly156Ser mutation caused polarity change of the amino acid at this site and formation of side chains,leading to increase of protein instability,which may affect catalytic activity of structural domain.Meanwhile,both Mutation Taster and PolyPhen-2 online bioinformatics software also predicted the pathogenicity of this missense mutation with high scores.Conclusion:The heterozygous p.Gly 156Ser mutation is the direct cause of the reduced FⅦ in this proband.

This study primarily investigated the mechanism of Astragalus polysaccharides(APS), a Chinese medicinal material, in regulating the Nrf2/SLC7A11/GPX4 signaling pathway to induce ferroptosis in ovarian cancer cells(Caov-3 and SKOV3 cells). Caov-3 and SKOV3 cells were divided into control(Vehicle) group, APS group, glutathione peroxidase 4 inhibitor(RSL3) group, and APS+RSL3 group. After 48 h of intervention, the activity and morphology of the cells in each group were observed. The cell counting kit-8(CCK-8) method was used to determine the half-maximal inhibitory concentration(IC_(50)), while colony formation and EdU assays were conducted to assess cell proliferation. Biochemical reagents were used to detect lipid reactive oxygen species(L-ROS), malondialdehyde(MDA), divalent iron ions(Fe~(2+)), and glutathione(GSH) in Caov-3 cells. Transmission electron microscopy was employed to observe the morphological changes of mitochondria in Caov-3 cells. Bioinformatics analysis were used to screen potential target genes of APS in ovarian cancer cells. Western blot and RT-PCR were applied to measure the protein and mRNA expression of Nrf2, SLC7A11, and GPX4. The results revealed that APS effectively inhibited the activity and proliferation of ovarian cancer cells, significantly increased the expression levels of L-ROS, MDA, and Fe~(2+)(P<0.001), and significantly reduced the expression level of GSH(P<0.001). Under electron microscopy, the mitochondria of Caov-3 cells appeared significantly smaller, with a marked increase in the density of the bilayer membrane, disappearance of mitochondrial cristae, and rupture of the outer mitochondrial membrane. These effects were more pronounced when APS was combined with RSL3. Bioinformatics screening identified Nrf2, SLC7A11, and GPX4 as potential target genes for APS in ovarian cancer cells. APS was shown to reduce the protein and mRNA expression of Nrf2, SLC7A11, and GPX4(P<0.01), with the APS+RSL3 showing even more significant effects(P<0.001). In conclusion, APS can induce ferroptosis in ovarian cancer cells, and its mechanism may be related to the regulation of the Nrf2/SLC7A11/GPX4 signaling pathway, providing an experimental basis for the use of APS injections in the treatment of ovarian cancer.

Objective: To explore the combination of metabolism-related chronic diseases associated with the prevalence of non-alcoholic fatty liver disease (NAFLD) in community residents in Shanghai. Methods: The baseline data of Shanghai Suburban Adult Cohort and Biobank were used to understand the prevalence of five metabolism-related chronic diseases, including obesity, hypertension, hyperlipidemia, gout and diabetes, based on questionnaire survey, physical examination and blood biochemical detection. NAFLD was diagnosed by B-ultrasound detection and questionnaire. Multivariable logistic regression model was used to analyze the association of 31 metabolism-related chronic diseases combinations with the prevalence of NAFLD. Results: The median age (Q1, Q3) of 65 477 subjects was 60 (51, 66) years, and men accounted for 40.6%. The overall prevalence of NAFLD was 38.2%, and the prevalence of HAFLD in patients without any of the five metabolism-related chronic diseases was 12.0%. The chronic disease combination with the strongest association with NAFLD was obesity + hypertension + hyperlipidemia + gout + diabetes in the total population (OR=37.94, 95%CI: 31.02-46.41), in women (OR=36.99, 95%CI: 28.78-47.54) and in age group ≥60 years (OR=36.19, 95%CI: 28.25-46.36). The chronic disease combination with the strongest association with NAFLD was obesity + hyperlipidemia + gout + diabetes in men (OR=50.70, 95%CI: 24.62-104.40) and in age group <60 years (OR=49.58, 95%CI: 24.22-101.47). Conclusions: The prevalence of NAFLD in community residents in Shanghai was high. Attention needs to be paid to health of obese people and weight loss should be promoted for them. Community health education should be strengthened for patients complicated with gout, diabetes, hyperlipidemia and hypertension and it is necessary to correct abnormal serum uric acid, blood sugar, blood lipids and blood pressure in a timely manner to reduce the risk of NAFLD.

Functional dyspepsia(FD) is a prevalent functional gastrointestinal disease characterized by recurrent and long-lasting symptoms that significantly impact the quality of life of patients. Currently, western medicine treatment has not made breakthrough progress and mainly relies on symptomatic therapies such as gastrointestinal motility agents, acid suppressants, antidepressants/anxiolytics, and psychotherapy. However, these treatments have limitations in terms of insufficient effectiveness and safety. Traditional Chinese medicine(TCM) possesses unique advantages in the treatment of FD. Through literature search in China and abroad, it has been found that the mechanisms of TCM in treating FD is associated with various signaling pathways, and research on these signaling pathways and molecular mechanisms has gradually become a focus. The main signaling pathways include the SCF/c-Kit signaling pathway, 5-HT signaling pathway, CRF signaling pathway, AMPK signaling pathway, TRPV1 signaling pathway, NF-κB signaling pathway, and RhoA/ROCK2/MYPT1 signaling pathway. This series of signaling pathways can promote gastrointestinal motility, alleviate anxiety, accelerate gastric emptying, reduce visceral hypersensitivity, and improve duodenal micro-inflammation in the treatment of FD. This article reviewed the research on TCM's regulation of relevant signaling pathways in the treatment of FD, offering references and support for further targeted TCM research in the treatment of FD.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Aim To explore the roles of miRNA-132 and its related proteins(Mecp2, CREB)in the mechanism of methamphetamine(MA)-induced neurotoxicity and dependence.Methods The rats were intraperitioneally injected(ip)with MA(10 mg·kg-1·d-1)to establish methamphetamine dependence model with different dependent time courses of 1 week, 2 weeks, and 4 weeks respectively.The miRNA-132 and Mecp2 mRNA were detected by RT-qPCR, and the Mecp2, p-Mecp2, CREB and p-CREB proteins were detected by Western blot in the tissues of frontal cortex and hippocampus.Results In the frontal cortex, the miRNA-132 and Mecp2 mRNA were up-regulated in MA-dependent groups(P<0.05 and P<0.01), while the Mecp2 protein were down-regulated(P<0.01).MA could promote the phosphorylation of Mecp2 protein in the frontal cortex(P<0.01).In hippocampus, the miRNA-132 was down-regulated in the MA-dependent groups, but Mecp2 mRNA was up-regulated(P<0.05).Mecp2 protein increased in MA-dependent 1 week group(P<0.05), and then recovered with the prolonged time of MA dependence, then decreased in MA-dependent 4 weeks groups(P<0.05)in hippocampus.The phosphorylation level of Mecp2 was significantly decreased in the 1 week group(P<0.01), and then increased in the 2 weeks group(P<0.01)in hippocampus.Conclusions MA could induce an abnormal expression of miRNA-132 in the frontal cortex and hippocampus, and miRNA-132 might inhibit the translation of Mecp2 mRNA and induce the decrease expression of Mecp2 protein in the frontal cortex.But in hippocampus, miRNA-132 does not show the correlation with the Mecp2 expression trend of the frontal cortex.And miRNA-132 regulation does not depend on the expression of Mecp2 in hippocampus.

OBJECTIVE:
To evaluate the safety and effectiveness of Qishe Pill () on neck pain in real-world clinical practice.
METHODS:
A multi-center, prospective, observational surveillance in 8 hospitals across Shanghai was conducted. During patients receiving 4-week Qishe Pill medication, Visual Analogue Scale (VAS) and Neck Disability Index (NDI) assessments have been used to assess their pain and function, while safety monitoring have been observed after 2 and 4 weeks.
RESULTS:
Results from 2,023 patients (mean age 54.5 years) suggest that the drug exposure per unit of body mass was estimated at 3.41 ± 0.62 g/kg. About 8.5% (172/2,023) of all participants experienced adverse events (AEs), while 3.8% (78/2,023) of all participants experienced adverse reaction. The most common AEs were gastrointestinal events and respiratory events. The VAS score (pain) and NDI score (function) significantly decreased after 4-week treatment. An effect-quantitative analysis was also conducted to show that the normal clinical dosage may be consider as 3-4 g/kg, at which dosage the satisfactory pain-relief effect may achieve by 40-mm reduction in VAS.
CONCLUSION
These findings showed that patients with cervical radiculopathy who received Qishe Pill experienced significant improvement on pain and function. (Registration No. NCT01875562).
