BackgroundPatients with depressive disorder commonly experience sleep disturbances. Previous studies have indicated that group exercise therapy is beneficial in alleviating depressive symptom among patients with depressive disorder. However， there is a lack of research on the impact of group exercise therapy on improving sleep quality in patients with depressive disorder. ObjectiveTo explore the impact of group exercise therapy on sleep quality in patients with acute mild-to-moderate depression during the acute phase， so as to provide references for clinically improving the sleep quality of patients with mild to moderate depressive disorder during the acute phase. MethodsFrom December 2018 to July 2021， patients with mild-to-moderate depressive disorder during the acute phase （n=40）， who met the diagnostic criteria for depressive disorder according to International Classification of Diseases， tenth edition （ICD-10） ，were recruited from the outpatient clinic of Beijing Anding Hospital， Capital Medical University. All participants underwent an 8-week moderate-intensity group exercise therapy program comprising three sessions per week， each lasting 60 minutes. Assessments were conducted at baseline and after 2， 4， 6 and 8 weeks of intervention using Visual Analogue Scale （VAS）， Hamilton Depression Scale-17 item （HAMD-17） and Pittsburgh Sleep Quality Index （PSQI）. The reduction scores at each time point relative to baseline treated as the dependent variables， time as the independent variable， baseline scores as covariates， with time as a fixed effect and baseline values as random effects. Data were analyzed using a linear mixed-effects model. ResultsThe PSQI scores of patients at baseline， 2， 4 ， 6 and 8 weeks after the intervention were （10.62±5.12）， （9.07±3.58）， （7.39±3.66）， （6.54±3.84） and （5.50±3.41）， respectively. The results of linear mixed effect model analysis showed that after 2， 4， 6 and 8 weeks of intervention， patients scored lower than baseline， with statistically significant differences observed in all cases （P<0.01）. The HAMD-17 sleep fcctor scores at baseline， 2， 4， 6 and 8 weeks were （2.25±1.56）， （2.06±1.49）， （1.36±1.27）， （1.22±1.46） and （0.97±1.34）， respectively. The results of linear mixed effects model analysis showed that the HAMD-17 sleep factor scores of 4， 6 and 8 weeks of intervention were lower than that of baseline， and the difference was statistically significant （P<0.05 or 0.01）. The VAS scores at baseline， 2， 4， 6 and 8 weeks after the intervention were （3.18±2.17）， （4.74±2.22）， （6.01±2.31）， （6.54±2.16） and （7.90±1.64）， respectively. The results of linear mixed effect model analysis showed that VAS scores of 2， 4， 6 and 8 weeks of intervention were higher than baseline，and the difference was statistically significant （P<0.01）. ConclusionGroup exercise therapy may improve sleep quality and alleviate depressive symptoms in patients with mild-to-moderate depressive disorder during the acute phase. ［Funded by National Key Research and Development Plan Project （number， 2016YFC1307200）； Beijing Municipal Hospital Scientific Research and Cultivation Plan Project （number， PX2024070）］

Objective This clinical study aimed to evaluate the accuracy of a fully digital technique for mea-suring sagittal condylar inclination(SCI),as well as vali-dating whether differences existed between the left and right SCI values of the same participant,to provide a ref-erence for clinical practice.Methods Ten participants with good occlusal relationship and normal temporomandibular joint were recruited.Three methods were used to mea-sure the SCI values of the participants,namely,A(mechanical facebow transferring and mechanical articulator-based measuring method with physical protrusive interocclusal registration),B(face scan-based virtual facebow and virtual ar-ticulator-based measuring method with digital protrusive interocclusal registration),and C(jaw motion tracking system-based measuring method).With the group subjected to methods A and C as the control,the SCI values obtained by the three methods were statistically analyzed.The left and right SCI values of the same participant were also compared.Re-sults The left and right SCI values measured by method A were 41.70°±7.09° and 42.80°±8.62°,those by method B were 35.09°±12.49° and 37.63°±12.10°,and those by method C were 39.43°±8.72° and 38.45°±6.91°.No significant dif-ference existed among the SCI values measured by the three methods(P>0.05).Meanwhile,no statistical difference existed between the SCI values on the left and right sides of the same participant(P>0.05).Conclusion The accuracy of the virtual facebow and digital protrusive occlusal registration based SCI measuring method was the same as that of mechanical facebow based and jaw motion tracking system-based methods.The SCI values on the left and right sides of the same participant were similar.Clinically,an appropriate SCI measurement and setting strategy can be selected based on the actual situations.

Objective This clinical study aimed to as-sess the trueness of three intraoral scanners for the recor-ding of the maximal intercuspal position(MIP)to provide a reference for clinical practice.Methods Ten participants with good occlusal relationship and healthy temporomandibular joint were recruited.For the control group,facebow transferring procedures were performed,and bite registrations at the MIP were used to transfer maxillary and mandibular casts to a mechanical articulator,which were then scanned with a laboratory scanner to obtain digital cast data.For the experimental groups,three intraoral scanners(Trios 3,Carestream 3600,and Aoralscan 3)were used to obtain digital casts of the participants at the MIP following the scanning workflows endorsed by the corresponding manufacturers.Sub-sequently,measurement points were marked on the control group's digital casts at the central incisors,canines,and first molars,and corresponding distances between these points on the maxillary and mandibular casts were measured to calcu-late the sum of measured distances(DA).Distances between measurement points in the incisor(DI),canine(DC),and first molar(DM)regions were also calculated.The control group's maxillary and mandibular digital casts with the added mea-surement points were aligned with the experimental group's casts,and DA,DI,DC,and DM values of the aligned control casts were determined.Statistical analysis was performed on DA,DI,DC,and DM obtained from both the control and ex-perimental groups to evaluate the trueness of the three intraoral scanners for the recording of MIP.Results In the con-trol group,DA,DI,DC,and DM values were(39.58±6.40),(13.64±3.58),(14.91±2.85),and(11.03±1.56)mm.The Trios 3 group had values of(38.99±6.60),(13.42±3.66),(14.55±2.87),and(11.03±1.69)mm.The Carestream 3600 group showed values of(38.57±6.36),(13.56±3.68),(14.45±2.85),and(10.55±1.41)mm,while the Aoralscan 3 group had val-ues of(38.16±5.69),(13.03±3.54),(14.23±2.59),and(10.90±1.54)mm.Analysis of variance revealed no statistically sig-nificant differences between the experimental and control groups for overall deviation DA(P=0.96),as well as local devi-ations DI(P=0.98),DC(P=0.96),and DM(P=0.89).Conclusion With standardized scanning protocols,the three intra-oral scanners demonstrated comparable trueness to traditional methods in recording MIP,fulfilling clinical requirements.

Objective:To investigate the expression of PDLIM3 in the ectopic and orthotopic endometrium of endometriosis(EMT)patients,as well as in healthy endometrium,and to explore its relationship with clinical signifi-cance.Methods:Bioinformatics analysis based on the Gene Expression Omnibus(GEO)database was conduc-ted,and a prospective cohort study was undertaken,involving 58 EMT patients treated at West China Second Hospital of Sichuan University and 27 patients with other benign gynecological diseases as the control group from December 2019 to July 2020.Ectopic and orthotopic endometrium samples were obtained from EMT patients,and normal control samples were obtained from patients with other benign gynecological diseases.Real-time quantita-tive polymerase chain reaction(qPCR),western blot,and immunohistochemistry were utilized to investigate PD-LIM3 expression in various tissue samples.Clinical parameters were analyzed to determine the correlation be-tween PDLIM3 and clinical features.Results:Compared to orthotopic endometrial tissues of EMT patients and normal endometrial tissues of control subjects,the mRNA(F =46.05,P<0.05)and protein(F =238.6,P<0.05)expression levels of PDLIM3 in ectopic endometrial lesions were significantly upregulated.The average optical density(AOD)of PDLIM3 protein obtained through immunohistochemical experiments in ectopic endometrial le-sions showed a positive correlation with the degree of dysmenorrhea(r =0.86,P<0.05)and CA 125 level(r = 0.41,P<0.05)in EMT patients.But no obvious correlation was found between the expression level of PDLIM3 and disease stage,menstrual volume,and CA199 level(P>0.05).Conclusions:The expression level of PDLIM3 in endometriosis lesions was significantly upregulated and correlated with the degree of dysmenorrhea and serum CA125 level.These findings suggest that PDLIM3 may play a significant role in the development and progression of endometriosis and could serve as a potential therapeutic target.

Endometriosis, a heterogeneous, inflammatory, and estrogen-dependent gynecological disease defined by the presence and growth of endometrial tissues outside the lining of the uterus, affects approximately 5-10% of reproductive-age women, causing chronic pelvic pain and reduced fertility. Although the etiology of endometriosis is still elusive, emerging evidence supports the idea that immune dysregulation can promote the survival and growth of retrograde endometrial debris. Peritoneal macrophages and natural killer (NK) cells exhibit deficient cytotoxicity in the endometriotic microenvironment, leading to inefficient eradication of refluxed endometrial fragments. In addition, the imbalance of T-cell subtypes results in aberrant cytokine production and chronic inflammation, which contribute to endometriosis development. Although it remains uncertain whether immune dysregulation represents an initial cause or merely a secondary enhancer of endometriosis, therapies targeting altered immune pathways exhibit satisfactory effects in preventing disease onset and progression. Here, we summarize the phenotypic and functional alterations of immune cells in the endometriotic microenvironment, focusing on their interactions with microbiota and endocrine and nervous systems, and how these interactions contribute to the etiology and symptomology of endometriosis.

Alanine-serine-cysteine transporter 2 (ASCT2) is reported to participate in the progression of tumors and metabolic diseases. It is also considered to play a crucial role in the glutamate-glutamine shuttle of neuroglial network. However, it remains unclear the involvement of ASCT2 in neurological diseases such as Parkinson's disease (PD). In this study, we demonstrated that high expression of ASCT2 in the plasma samples of PD patients and the midbrain of MPTP mouse models is positively correlated with dyskinesia. We further illustrated that ASCT2 expressed in astrocytes rather than neurons significantly upregulated in response to either MPP⁺ or LPS/ATP challenge. Genetic ablation of astrocytic ASCT2 alleviated the neuroinflammation and rescued dopaminergic (DA) neuron damage in PD models in vitro and in vivo. Notably, the binding of ASCT2 to NLRP3 aggravates astrocytic inflammasome-triggered neuroinflammation. Then a panel of 2513 FDA-approved drugs were performed via virtual molecular screening based on the target ASCT2 and we succeed in getting the drug talniflumate. It is validated talniflumate impedes astrocytic inflammation and prevents degeneration of DA neurons in PD models. Collectively, these findings reveal the role of astrocytic ASCT2 in the pathogenesis of PD, broaden the therapeutic strategy and provide a promising candidate drug for PD treatment.

Objective:To understand and determine the biological properties of Chlamydia pneumonia (Cpn) hypothetical protein Cpn0423 and the mechanisms of which involved in Cpn0423-induced inflammatory response. Methods:The biological properties of Cpn0423 gene were analyzed using bioinformatic software. The subcellular localization of nucleotide-binding oligomerization domain-like receptor 2 (NOD2) in bone marrow-derived macrophages (BMDMs) was detected by confocal microscope. NOD2-siRNA was used to inhibit the expression of NOD2 at mRNA level. Cpn0423-induced macrophage inflammatory protein 2 (MIP-2) and IL-6 production in BMDMs were detected by ELISA. PCR was performed to detect Cpn0423 DNA in bronchoalveolar lavage fluid (BALF) of Cpn-positive patients.Results:The homology between Cpn0423 and other type Ⅲ secretion system effector proteins of Chlamydia ranged from 85% to 93%. NOD2-siRNA could effectively inhibit the expression of NOD2 at mRNA level in BMDMs ( P<0.001). Moreover, Cpn0423-induced production of MIP-2 [(920.5±99.1) pg/ml vs (130.1±11.5) pg/ml, P<0.001] and IL-6 [(266.2±58.4) pg/ml vs (165.7±21.5) pg/ml, P<0.001] in BMDMs were decreased following NOD2-siRNA pre-treatment. Cpn0423 DNA was detected in the BAlF of 83.3% (10/12) of Cpn-positive cases, but not in Cpn-negative cases. Conclusions:Cpn0423 induced inflammatory response in host cells through NOD2 pathway, which was closely related to the chronic inflammatory injury caused by Cpn.

Objective: To investigate the application value of real-time virtual sonography(RVS)in the diagnosis and treatment of complicated hepatolithiasis. Methods: The retrospective and descriptive study was conducted. The clinical data of 10 patients with complicated hepatolithiasis who were admitted to Hunan Provincial People′s Hospital between October 2017 and March 2018 were collected. There were 3 males and 7 females, aged from 40 to 69 years, with an average age of 57 years. Patients received abdominal color Doppler ultrasound examination, magnetic resonance cholangiopancreatography, and upper abdominal spiral computed tomography (CT) thinly scanning + enhanced examination. Data of CT examination were imported into RVS. RVS was used to locate hepatolithiasis, relationship between stones and vessels, anatomy of bile ducts and vessels in hepatic hilus. Surgical methods included RVS-guided hilar cholangiotomy, biliary stricturoplasty, bilateral hepatojejunostomy, hepatic segmentectomy (lobectomy), and hepatolithotomy. Observation indicators: (1) surgical and postoperative situations; (2) typical case analysis; (3) follow-up. Follow-up using outpatient examination was performed to detect residual stones up to June 2019. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results: (1) Surgical and postoperative situations: 10 patients underwent RVS-guided surgeries successfully for complicated hepatolithiasis, with successful match in RVS (difference between CT images and ultrosound images <2 mm). No residual stone was identified by choledochoscope during operation. The operation time and volume of intraoperative blood loss were 285 minutes (range, 210-360 minutes) and 200 mL (range, 100-600 mL), respectively. No blood transfusion was needed during the operations. The duration of hospital stay was 20.5 days (range, 14.0-29.0 days). There was no perioperative death. One patient had postoperative biliary leakage and abdominal infection, and was cured after conservative treatment. (2) Typical case analysis: the tenth patient, female, 60 years old, was diagnosed with complicated hepatolithiasis, and was prepared to undergo hepatolithotomy+ quadrate lobectomy and hilar cholangioplasty+ bilateral hepatojejunostomy. Preoperative CT images and intraoperative color Doppler ultrasound images of the patient were fused and matched on the sagittal section of the portal vein and the cross section of the right branch of portal vein, and stones and important vessels were marked on the images. After accurate positioning, a curette was used to remove the stones. Removal of biliary stones through hepatic parenchyma and peripheral dilated bile ducts was conducted at the site where stones obviously existed. After the stones were removed, the intrahepatic bile duct and hilar bile duct merged. The left end of the bile duct split was confirmed by real-time ultrasound. After location of portal vein was determined by ultrasound, vascular plastic surgery was perfomed to avoid stenosis. (3) Follow-up: 10 patients were followed up for 6-12 months, with a median follow-up time of 8 months. One of 10 patients was suspected residual stones at the right peripheral hepatic anterior lobe by postoperative angiography at 2 months after surgery, and was not removed stones by choledochoscope. The patient had no recurrent symptoms after T-tube removal. The other 9 patients had no residual stones. Conclusion RVS applied in complicated hepatolithiasis is helpful for the precise intraoperative diagnosis, and the surgical treatment can be safe and effective.
