Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels， but their effectiveness is limited. The mechanisms underlying its onset are complex， and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression， involving multiple pathways， including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 （TLR4/NLRP3）， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， brain-derived neurotrophic factor/tyrosine kinase receptor B （BDNF/TrkB）， cyclic AMP/protein kinase A/cAMP response element-binding protein （cAMP/PKA/CREB）， and others. Traditional Chinese medicine（TCM） is based on a holistic approach and the principle of treatment based on the differentiation of syndromes， regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems， involving liver Qi stagnation， heart spirit deficiency， kidney essence depletion， and spleen dysfunction. TCM compound treatments focus on soothing the liver， strengthening the spleen， calming the heart， and replenishing essence， with formulas such as Xiaoyaosan， Zishui Qinggan Yin， and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi， such as salidroside， ginsenoside Rb₁， astragaloside， and muscone. External TCM treatments， primarily acupuncture， aim to open the orifices and invigorate the spirit. Acupoints such as Baihui， Shenting， and Yintang are commonly used. Additionally， massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression， aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

Objective:To construct a column-line diagram diagnostic model based on serum and joint fluid inflammatory markers for the diagnosis of periprosthetic joint infections (PJI) after joint arthroplasty and to validate its predictive ability.Methods:The clinical data of 181 patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Affiliated Hospital of Chongqing Medical University from January 2015 to June 2020 were retrospectively collected as a modeling group. The best indicators for diagnosing PJI were screened by lasso regression, single-factor and multifactor analysis. By comprehensively considering the weights and intrinsic connections of the indicators, a column-line diagram diagnostic model was constructed and used to develop a clinical decision support system (CDSS). Prospectively, the clinical data of patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Hospital of Chongqing Medical University from July 2020 to December 2022 were collected as a validation group, and the diagnostic performance of the column-line diagram model was externally validated by methods such as receiver operating characteristic curve (ROC).Results:There were 85 cases of PJI in the 181 cases modeling group and 23 cases of PJI in the 49 cases validation group. Among the 27 potential factors analyzed by lasso regression analysis, body mass index (BMI), blood tests including platelet (PLT), absolute lymphocyte value, interferon γ (IFN-γ), ESR, IL-6, C-reactive protein, D-dimer, and joint fluid tests including C-reactive protein, IL-1, IL-4, IL-6, percentage of multinucleated neutrophils (PMN%), and CD64 may be potential indicators for the diagnosis of PJI. Univariate found significant differences between hematologic tests including sedimentation, C-reactive protein, IL-6, D-dimer and joint fluid tests including C-reactive protein, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, PMN%( P<0.05). Further multifactorial regression analysis screened serum IL-6, D-dimer, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, and percentage of multinucleated neutrophils, and based on that, the column-line graph model and CDSS system were constructed. The area under the ROC in the validation group was 0.978, and the AUC in the internal validation was 0.995; the C-index of the calibration curve was 99.50%, and the C-index of the internal validation was 99.53%, suggesting that the column-line diagram model has a good predictive ability. Conclusions:The column-line diagram for diagnosing PJI based on multiple diagnostic indicators showed good diagnostic performance. The CDSS system constructed by column-line diagrams could assist clinicians in diagnosing PJI and making reasonable strategies in time.

Objective To analyze the clinical characteristics of IgG4-related disease (IgG4-RD),guide the selection of therapeutic drugs,and to explore the significance of potential tumor identification for IgG4-RD.Methods A total of 92 patients diagnosed with IgG4-RD and admitted to this hospital from January 1,2017 to December 31,2021were selected as the research subjects by using the Yidu Cloud system.The clinical data conducted the summary analysis. The clinical characteristics of IgG4-RD were summarized.Results The mean age of IgG4-RD was definitely diagnosed in the 92 patients was (58.1±11.3)years old,with 65 male ca-ses (70.7％) and 27 female cases (29.3％).The most commonly affected organ tissues were lymph nodes (37 cases,40.2％),pancreas (33 cases,35.9％) and salivary glands (31 cases,33.7％).In the patients woth the 92 patients,28 cases (30.4％) had involvement of a single organ tissue,while 32 cases (34.8％) had involvement of two or more organs.In the 92 patients,89 cases received steroid therapy,and 71 cases received immunosup-pressive therapy,in which 45 cases (63.4％) used cyclophosphamide.The initial treatment effective rate (72.7％ vs. 55.6％) and one-year non-recurrence rate (38.2％ vs. 20.0％) of the steroid combined immuno-suppressive therapy group were better than those of the single steroid group,but the differences were not sta-tistically significant (P>0.05).The proportion of the patients with tumor comorbidity and IgG4 level>40 g/L (18.2％) was significantly higher than that of the non-tumor comorbidity (1.2％),and the difference was statistically significant (P<0.05).However,there was no statistically significant difference in the proportion of patients with tumor comorbidity compared to the non-tumor comorbidity in other IgG4 level groups (P>0.05).Conclusion IgG4-RD is more common in middle-aged and elderly men,lymph nodes,pancreas and sal-ivary glands are commonly involved,and most patients have the double organs and multiple organs involve-ment. The combination use of hormone and immunosuppressant in treatment is recommended .The IgG4 lev-el>40 g/L in the patients with IgG4-RD may has the suggestive significance for complicating tumor.

Objective:Methamphetamine(METH)is an illicit psychoactive substance that can damage various organs,with the urinary system being one of its significant targets.This study aims to explore the role of microtubule affinity-regulating kinase 4(MARK4)in METH-induced acute kidney injury(AKI). Methods:A total of 10 healthy adult male C57BL/6 mice were randomly divided into a control group and a METH group,5 mice in each group.The METH group was administered METH(20 mg/kg,intraperitoneally,once daily for 3 consecutive days),while the control group received an equal volume of physiological saline.The mice were executed 24 hours after the final injection,and the success of the AKI model was detected by blood serum creatinine,blood urea nitrogen,and renal HE staining.Proteins differentially expressed between kidney tissues with METH-induced AKI and normal kidney tissues were screened by proteomics techniques and subjected to gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)and bioinformatics analysis.The accuracy of proteomic data was validated using Western blotting,and the expression levels of MARK4 and cleaved caspase-3 in mouse kidneys were measured.We further explored the role of MARK4 in METH-induced AKI.Firstly,a METH toxicity model was established in BUMPT cells to screen the appropriate concentration and time of METH treatment;the viability of BUMPT cells after METH treatment and the expression of cleaved caspase-3 were detected by interfering with MARK4 expression through inhibitors. Results:The proteomic analysis of kidney tissues from METH and control groups screened for a total of 17 differentially expressed proteins,of which 11 were up-regulated and 6 were down-regulated(all P＜0.05).The expression levels of MARK4 and cleaved caspase-3 were elevated in the kidneys of METH-treated mice(both P＜0.05).The activity of BUMPT cells gradually decreased with increasing METH treatment concentration(all P＜0.05),where the viability of BUMPT cells decreased to about 60％after METH treatment at 4 mmol/L.Compared with the control group,expression levels of MARK4 and cleaved caspase-3 were increased with higher METH concentrations and longer exposure times in a concentration-and time-dependent manner(all P＜0.05).Inhibition of MARK4 expression improved METH-induced decrease in BUMPT cell activity,down-regulated the expression of cleaved caspase-3,and decreased the apoptosis of BUMPT cells induced by METH. Conclusion:MARK4 is highly expressed in a mouse model of METH-induced AKI,and MARK4 mediates METH-induced AKI by regulating cell apoptosis.

Objective:To examine whether multiple-course prophylactic intravesical instillation chemotherapy is superior to single-course chemotherapy in preventing bladder tumor recurrence after radical nephroureterectomy(RNU)for primary upper tract urothelial carcinoma(UTUC).Methods:A comprehensive literature search was performed using the PubMed, Wanfang Data and China National Knowledge Infrastructure and all publications before March 2021 about clinical trials comparing the effects of single-course and multiple-course prophylactic intravesical instillation chemotherapy after RNU for UTUC were retrieved.Analysis was performed using Stata/SE 12.0.Results:Seven trials included a total of 998 patients, with 473 participants receiving multiple-course and 525 receiving single-course intravesical instillation chemotherapy.Bladder cancer recurrence occurred in 69 out of 473 patients(14.6%)with multiple-course chemotherapy and in 123 out of 525 patients(23.4%)with single-course chemotherapy.The absolute risk reduction was 8.8% and the relative risk reduction was 37.6%.Compared with a single-course instillation, the pooled OR of bladder cancer recurrence was 0.55(95% CI: 0.40-0.76, P<0.001)for multiple-course instillations.No serious adverse events were reported. Conclusions:Compared with single-course instillation chemotherapy, multiple-course prophylactic intravesical instillation chemotherapy significantly decreases the risk of bladder cancer recurrence in primary UTUC patients treated with RNU, indicating multiple intravesical instillation chemotherapy is superior to single instillation chemotherapy.

Gliomas are the most common central nervous system tumours; they are highly aggressive and have a poor prognosis. RGS16 belongs to the regulator of G-protein signalling (RGS) protein family, which plays an important role in promoting various cancers, such as breast cancer, pancreatic cancer, and colorectal cancer. Moreover, previous studies confirmed that let-7c-5p, a well-known microRNA, can act as a tumour suppressor to regulate the progression of various tumours by inhibiting the expression of its target genes. However, whether RGS16 can promote the progression of glioma and whether it is regulated by miR let-7c-5p are still unknown. Here, we confirmed that RGS16 is upregulated in glioma tissues and that high expression of RGS16 is associated with poor survival. Ectopic deletion of RGS16 significantly suppressed glioma cell proliferation and migration both in vitro and in vivo. Moreover, RGS16 was validated as a direct target gene of miR let-7c-5p. The overexpression of miR let-7c-5p obviously downregulated the expression of RGS16, and knocking down miR let-7c-5p had the opposite effect. Thus, we suggest that the suppression of RGS16 by miR let-7c-5p can promote glioma progression and may serve as a potential prognostic biomarker and therapeutic target in glioma.

Objective:To explore the efficacy and safety of robot assisted laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse.Methods:The data of 16 patients who underwent robot assisted laparoscopic sacrocolpopexy in Beijing Hospital from September 2019 to May 2022 were collected. The average age was (73.5±9.3) years, the preoperative course was 4-240 months, the body mass index was (24.2±1.7) kg/m 2, the number of births was (1.7±0.8), and the quantitative index of pelvic organ prolapse (POP-Q) was grade Ⅲ -Ⅳ. The maximum urine flow rate before operation was (9.6±3.4) ml/s, the maximum detrusor pressure during urination was 26 (20, 32) cmH 2O, the first sense urine volume of the bladder was (119.1±39.4) ml, the first sense urine urgency volume of the bladder was (253.6±75.7) ml, the maximum bladder pressure capacity was (406.0±79.8) ml, and the residual urine volume was 10 (10, 28) ml. The preoperative PFDI-20 score was 100 (70, 122) and the PFIQ-7 score was 107 (90, 160). During the robot assisted laparoscopic sacrocolpopexy, the right area of the sacral promontory was exposed, the anterior and posterior walls of the uterus were separated, and the 2 cm small hole was separated from the right broad ligament of the uterus. The mesh was cut into a "Y" shape and passed through the small hole. The anterior and posterior leaves of the Y-shaped mesh were sutured to fix the cervix, and the other end was fixed to the anterior longitudinal ligament of the sacrum. The operation time and intraoperative bleeding were observed. The effect of surgery was evaluated by preoperative and postoperative urodynamic imaging, POP-Q stage, PFDI-20 score and PFIQ -7 score. Results:All the 16 operations were successfully completed. No injury of urethra, bladder, rectum, important blood vessels and nerves occurred during the operation. The average operation time was (255.6±56.0) min, and the average amount of bleeding was (28.8±18.2) ml. There was no inhibitory contraction wave in 7 patients (44%) before operation, suggesting that there was detrusor overactivity. After operation, the detrusor overactivity disappeared or significantly decreased in 7 patients. The postoperative follow-up period was 3-36 months. During the follow-up period, one patient had recurrence, and the rest had no prolapse and urination problems. The POP-Q stage was reduced to grade 0-Ⅰ after the operation. The subjective satisfaction rate of patients was 94%. The PFDI-20 score [13(8, 24)] and PFIQ -7 score [11(6, 15)] after operation were significantly reduced ( P<0.001), the initial urgent volume of bladder (272.5±88.5) ml was significantly increased compared with that before operation ( P=0.038), and the maximum volume of bladder (427.2±79.2) ml was significantly increased compared with that before operation ( P=0.006). Image urodynamics showed that the patient basically recovered the pelvic floor anatomy and achieved functional reduction. Conclusions:Robot assisted laparoscopic sacrocolpopexy has good subjective and objective effects in POP, low recurrence rate and less complications. It needs a larger sample size study for confirming the improvement of bladder function.

Objective:To explore the potential relationship of urethral pressure profilometry and the complications of artificial urethral sphincter (AUS) implantation.Methods:The clinical data of patients who underwent AUS implantation in Beijing Hospital from March 2019 to March 2022 were retrospectively analyzed. All the patients were male. The average course of disease was 43.1 months(ranging 11-120 months). The average age was (68.6±13.2) years. The median number of pads used was 4.5 (3.0, 6.0). The preoperative maximum urethral pressure (MUP) was (84.6±25.5) cmH 2O, and the maximum urethral closure pressure (MUCP) was 51.0 (41.0, 74.0) cmH 2O. AUS implantation was performed through a single perineal incision in all patients. The sleeve size was mainly determined by the measured urethral circumference of the patient. After installation of all components, the urethral pressure profilometry was performed under the state of device inactivation and activation. The pump was activated 6 weeks after the operation, and telephone follow-up was performed 3 months after the activation of the device. The urinary control and complications were recorded. The results of follow-up were compared with the results of urethral pressure profilometry, and the preliminary conclusions were drawn. Results:In this study, 3 patients (20%) received 4.0cm cuffs, 10 patients (66.7%) received 4.5cm cuffs, and 2 patients (13.3%) received 5.0cm cuffs. The MUP and MUCP of AUS device in inactivated state were (82.5±30.2) cmH 2O and 51.0(48.0, 77.0) cmH 2O. In the activated state, MUP was (138.9±21.7) cmH 2O and MUCP was 109.0(94.0, 133.0) cmH 2O. Compared with that before operation, the urethral pressure in the inactivated state did not increase significantly (all P > 0.05), while the urethral pressure in the activated state increased significantly (all P < 0.001). The patients were followed-up for 3-33 months. Thirteen patients (86.7%) used the initial installation device, and all of them met the standard of social continence. One patient died of cerebrovascular accident. One patient took out the device due to urethral erosion. The incidence of complications was 26.7% (4/15), including painless hematuria in 2 cases, scrotum and penis infection in 1 case, and urethral erosion in 1 case. The MUP and MUCP of these patients were (100.0 ± 40.7) cmH 2O and (80.8 ± 39.7) cmH 2O respectively. In the intraoperative active state, the MUP was (151.5 ± 15.3) cmH 2O and the MUCP was (123.0 ± 17.2) cmH 2O. The MUP of the other 3 patients in the device activation state was significantly higher than the average value, and all of them were above 150 cm H 2O, except one patient who was infected due to cognitive problems and chronic urinary retention. In 11 patients without complications, the MUP and MUCP were (76.1±24.7) cmH 2O and (55.1±20.0) cmH 2O respectively. In the intraoperative active state, the MUP was (134.4±22.5) cmH 2O and the MUCP was (108.5±29.8) cmH 2O. Conclusions:AUS implantation has a definite curative effect. Poor comprehension, and MUP higher than 150 cmH 2O in the activated state of the device may be risk factors for complications.

Objective:To evaluate the efficacy and safety of robotic arm assisted laparoscopic hysterosacral fixation in patients with pelvic organ prolapse(POP), and its impact on lower urinary tract function.Methods:This study retrospectively analyzed the clinical data of POP patients who had undergone robotic arm assisted laparoscopic hysterosacral fixation at our center from June 2019 to October 2020, and conducted exploratory research.Results:A total of 6 patients were included in the study, with POP quantitative staging above stage Ⅲ.The ages ranged from 70 to 82 years.The number of births each patient had given ranged from 1 to 3, & all were via vaginal deliveries.There were no significant changes in urodynamic parameter scores in any patients before and after surgery, but half of the patients had detrusor overactivity before surgery, which all disappeared after surgery.In addition, synchronous X-ray images showed that the postoperative pelvic organs were closer to the normal anatomical position.At the same time, quantitative staging of POP had achieved clear improvement, and related scale scores also significantly improved.One patient complained of occasional lumbar and back discomfort with postoperative over-stretching during outpatient review, which improved after symptomatic treatment.Conclusions:robotic arm assisted Laparoscopic hysterosacral fixation is satisfactory in efficacy and safety for POP patients, with good postoperative restoration of the uterus to the anatomical position and has insignificant influence on the function of the lower urinary tract.It is worth further assessment for wide application.

Purpose: Microtubule-associated protein 1 light chain 3B (LC3B) serves as a key component of autophagy,which is associated with the progression of carcinoma. Yet, it is still unclear whetherLC3B is also an independent risk factor for intrahepatic cholangiocarcinoma (ICC). We aimto explore the predictive value of LC3B on prognosis of ICC, and to establish a novel andavailable nomogram to predict relapse-free survival (RFS) and overall survival (OS) for thesepatients after curative-intent hepatectomy. Materials and Methods: From August 2004 to March 2017, 105 ICC patients were eligibly enrolled in the ThirdAffiliated Hospital of Sun Yat-sen University. Preoperative clinical information of enrolledpatients was collected. Expression LC3B in the ICC specimen was detected by immunohistochemistry. Results: The 5-year RFS and OS in this cohort were 15.7% and 29.6%, respectively. On multivariateCox regression analysis, independent risk factors for 5-year OS were cancer antigen 125,microvascular invasion, LC3B expression and lymph node metastasis. Except for the above4 factors, neutrophil/lymphocyte ratio and tumor differentiation were independent factorsfor 5-year RFS. The area under the curve of nomograms for OS and RFS were 0.820 and0.747, respectively. Conclusion The nomograms based on LC3B can be considered as effective models to predict postoperativesurvival for ICC patients.
