Objective: Patients with late life depression sometimes refuse to receive electroconvulsive therapy (ECT) owing to its adverse reactions. To alleviate patient’s resistance, a novel ECT stimulation strategy named mixed-strategy ECT (msECT) was designed in which patients are administered conventional ECT during the first three sessions, followed by low energy stimulation during the subsequent sessions. However, whether low energy electrical stimulation in the subsequent stage of therapy affect its efficacy and reduce adverse reactions in patients with late life depression remains unknown. To explore differences between msECT and regular ECT(RECT) with respect to clinical efficacy and side effects Methods: This randomized, controlled trial was conducted from 2019 to 2021 on 60 patients with late life depression who were randomly assigned to two groups: RECT or msECT. A generalized estimating equation (GEE) was used to compare the two stimulation strategies regarding their efficacy and side effects on cognition. Chi-squared test was used to compare side effects in the two strategies. Results: In the intent-to-treat group, the GEE model suggested no differences between-group difference in Hamilton Depression Rating Scale-17 score over time (Wald χ2=7.275, p=0.064), whereas the comparison of side effects in the two strategies favored msECT (Wald χ2=8.463, p=0.015) as fewer patients had adverse events during the second phase of treatment with msECT (χ2 =13.467, p=0.004). Conclusion msECT presents its similar efficacy to RECT. msECT may have milder side effects on cognition.

OBJECTIVE: To investigate the incidence and potential influence factors that contribute to chronic post-surgical pain (CPSP) in elderly patients with urinary tract tumors who underwent laparoscopic procedures. METHODS: A retrospective study was conducted to collect the clinical data of 182 elderly patients with urinary tract tumors who were ≥65 years and underwent laparoscopic surgery from October 2021 to March 2022 in Peking University Third Hospital. The patients'demographic information, medical history and the severity of postoperative pain were collected. Telephone follow-ups were made 6 months after surgery, and the patients' CPSP conditions were recorded. The diagnostic criteria of CPSP were referred to the definition made by the International Association for the Study of Pain (IASP): (1) Pain that developed or increased in intensity after surgical procedure and persisted for at least 3 months after surgery; (2) Pain that localized to the surgical field or projected to the innervation territory of a nerve situated around the surgical area; (3) Pain due to pre-existing pain conditions or infections and malignancy was excluded. The patients were divided into two groups based on CPSP diagnosis. Risk factors that predisposed the patients to CPSP were identified using univariate analysis. A multivariate Logistic regression model using back-forward method was designed, including both variables that significantly associated with CPSP in the univariate analysis (P < 0.1), and the variables that were considered to have significant clinical impact on the outcome. RESULTS: Two hundred and sixteen patients with urinary tract tumors who had undergone laparoscopic surgery were included, of whom, 34 (15.7%) were excluded from the study. For the remaining 182 patients, the average age was (72.6±5.2) years, with 146 males and 36 females. The incidence of CPSP at the end of 6 months was 31.9% (58/182). Multiva-riate regression analysis revealed that age ≥75 years (OR=0.29, 95% CI: 0.12-0.73, P=0.008) was the protecting factors for postoperative chronic pain in the elderly patients with urinary tract tumors undergoing surgical treatment, while renal cancer (compared with other types of urinary tract tumors) (OR=3.68, 95% CI: 1.58-8.58, P=0.003), and the 24 h postoperative moderate to severe pain (OR=2.57, 95% CI: 1.14-5.83, P=0.024) were the independent risk factors affecting CPSP. CONCLUSION Age < 75 years, renal cancer and the 24 h postoperative moderate to severe pain are influence factors of the occurrence of CPSP after laparoscopic surgery in elderly patients with urinary tract tumors. Optimum postoperative multimodal analgesia strategies are suggested to prevent the occurrence of CPSP.

OBJECTIVE: To explore the method of measuring root volume with cone-beam computed tomography (CBCT) three-dimensional reconstruction technology, and to study root length and root volume of upper and lower central incisors in patients with skeletal Class Ⅲ malocclusion treated by surgical orthodontic treatment. METHODS: Twenty patients with skeletal Class Ⅲ malocclusion undergoing surgical orthodontic treatment were selected. CBCT data at three time points, before decompensation treatment (T0), after decompensation treatment (before orthognathic surgery, T1), and the end of post-operative orthodontic treatment (T2) were collected. Three-dimensional reconstruction technology was used to measure the root length and root volume of the upper and lower central incisors (including total root volume, cervical root and apical root), calculate the percentage of reduction volume, and measure the distance of tooth movement after orthodontic treatment. Data were statistically analyzed by SPSS 20.0 software. Least significant difference (LSD) method was used for pair comparison between the groups subject to normal distribution, and non-parametric test was used for comparison between the groups not subject to normal distribution. The differences of root length and root volume of upper and lower incisors were compared, and the characteristics of root absorption were analyzed. RESULTS: Root length and root volume of the upper and lower central incisors were reduced during the surgical orthodontic treatment (P < 0.05) in cases. Both the root volume of cervical root and apical root were significantly reduced (P < 0.05), the reduction of apical root was more significant. The percentage of root volume reduction of the upper central incisor was (30.51±23.23)%, and lower central incisor (23.24±11.96)%. Compared with the upper central incisor, the root volume reduction amount and percentage of the lower central incisor were smaller, and apical root volume reduction of the upper central incisor was greater than that of the lower central incisor, which was statistically significant (P < 0.05). During pre-surgical orthodontic treatment, maxillary central incisor palatal moving was in a controlled tipping manner, and the mandibular central incisor tipped labially. CONCLUSION In patients with skeletal Class Ⅲ malocclusion, root length and total root volume of upper and lower central incisors decreased during surgical orthodontic treatment. Root volume measurement indicated that the cervical root also had root resorption. The difference in root resorption of the upper and lower central incisors might be related to the distance and direction of teeth movement. CBCT three-dimensional reconstruction will compensate for the limitation of root length measurement in evaluating root resorption.

The relationship between androgen and prostate cancer treatment has plagued the field of urologic oncology. To investigate the efficacy and safety of bipolar androgen therapy (BAT) followed by immune checkpoint inhibitor therapy in patients with metastatic castration resistant prostate cancer (mCRPC). In August 2020, Beijing Hospital conducted an investigator-initiated study: Bipolar androgen therapy followed by immune checkpoint inhibitor therapy in metastatic castration resistant prostate cancer. Up to now, the study has included 4 patients who completed the entire cycle of treatment. The mean age of the patients was 74.5 (68 to 82) years old, the mean prostate-specific antigen (PSA) was 20.8 (9.9 to 8.36) μg/L, the mean testosterone was 0.50 (0.00 to 1.81) μg/L, and the Gleason score were 10 and 9, 7, 7 respectively. The pain scale score before treatment was 1.5 (1 to 2). In this study, 4 patients completed the entire cycle of treatment, and the treatment effect of the patients showed great heterogeneity. PSA in case 1 decreased from 24.0 μg/L to 0.47 μg/L, testosterone increased from 0.175 6 μg/L to 2.62 μg/L. PSA in case 2 increased from 9.939 μg/L to 168.536 μg/L, and testosterone increased from 0.0 μg/L increased to 2.85 μg/L. PSA increased from 13.31 μg/L to 39.278 μg/L in case 3, testosterone increased from 0.0 μg/L to 2.54 μg/L. and PSA increased from 36.0 μg/L to 350.2 μg/L in the case 4, testosterone increased from 1.81 μg/L to 3.85 μg/L. Except for one patient who showed significant PSA remission, the PSA levels of the remaining three patients remained high overall. There were no adverse reactions reported in 4 patients. In the follow-up, case 1 continued to use PD-1 monoclonal antibody (median progression free survival time was 10 months). Two patients who had previously been resistant to enzalutamide received enzalutamide again after the whole cycle of treatment, and their PSA decreased again, which indicated that the patient was sensitive to enzalutamide again. BAT had a certain therapeutic effect on mCRPC patients, and the safety was controllable. Its tumor control effect still needed long-term follow-up verification in large-sample clinical trials. BAT has a certain therapeutic effect on mCRPC patient, especially the resensitivity of tumors to enzalutamide can be restored. Immune checkpoint inhibitors may have therapeutic potential in patients with prostate cancer treated with BAT and enzalutamide.

Multidrug resistance (MDR) is the main cause of clinical treatment failure and poor prognosis in cancer. Targeting P-glycoprotein (P-gp) has been regarded as an effective strategy to overcome MDR. In this work, we reported our preclinical studies of the triazolo[1,5-a]pyrimidine-based compound WS-716 as a highly potent, specific, and orally active P-gp inhibitor. Through direct binding to P-gp, WS-716 inhibited efflux function of P-gp and specifically reversed P-gp-mediated MDR to paclitaxel (PTX) in multiple resistant cell lines, without changing its expression or subcellular localization. WS-716 and PTX synergistically inhibited formation of colony and 3D spheroid, induced apoptosis and cell cycle arrest at G2/M phase in resistant SW620/Ad300 cells. In addition, WS-716 displayed minimal effect on the drug-metabolizing enzyme cytochrome P4503A4 (CYP3A4). Importantly, WS-716 increased sensitivity of both pre-clinically and clinically derived MDR tumors to PTX in vivo with the T/C value of 29.7% in patient-derived xenograft (PDX) models. Relative to PTX treatment alone, combination of WS-716 and PTX caused no obvious adverse reactions. Taken together, our preclinical studies revealed therapeutic promise of WS-716 against MDR cancer, the promising data warrant its further development for cancer therapy.

Ischemic heart diseases are one of the major causes of death worldwide. Effective restoration of blood flow can significantly improve patients’ quality of life and reduce mortality. However, reperfusion injury cannot be ignored. Flavonoids possess well-established antioxidant properties; They also have other benefits that may be relevant for ameliorating myocardial ischemia-reperfusion injury (MIRI). In this review, we focus on flavonoids with cardiovascular-protection function and emphasize their pharmacological effects. The main mechanisms of flavonoid pharmacological activities against MIRI involve the following aspects: a) antioxidant, b) anti-inflammatory, c) anti-platelet aggregation, d) anti-apoptosis, and e) myocardial-function regulation activities. We also summarized the effectiveness of flavonoids for MIRI.

OBJECTIVE: To investigate the clinical features, radiologic scores and clinically relevant risk factors prognosis of secondary interstitial lung disease (ILD) in patients with systemic lupus erythematosus (SLE). METHODS: In this study, 60 SLE patients in Department of Rheumatology of the First Affiliated Hospital of Baotou Medical College and Taizhou First People's Hospital from January 2015 to March 2019 were retrospectively analyzed. All of those 60 patients with SLE underwent lung high resolution computed tomography (HRCT) examination. We used a 1 ∶1 case-control study. There was a matching of age and gender between the two groups. Thirty patients with SLE related ILD (SLE-ILD) were in the case group, and 30 patients with SLE without ILE (SLE non-ILD) were in the control group. The clinical features, pulmonary function test, radiologic characteristic of SLE patients were collected and were used to analyze SLE-ILD. RESULTS: In this study, we reached the following conclusions: First, there were statistically significant differences in chest tightness/shortness of breath, Raynaud's phenomenon, and Velcro rale between SLE-ILD and SLE non-ILD patients (both P < 0.05); Second, hemoglobin (Hb) and albumin (ALB) in the patients of SLE-ILD had a significant decrease compared with the patients of SLE non-ILD. Blood urea nitrogen (BUN), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased in SLE-ILD patients compared with SLE non-ILD patients, the difference had statistical significance (P < 0.05); Third, for SLE-ILD patients, the most common type was non-specific interstitial pneumonia (NSIP), followed by usual interstitial pneumonia and lymphocytic interstitial pneumonia; Fourth, there was no significant difference in clinical-radiology-physiology scores between the different ILD types (P>0.05), similarly, the lung HRCT score and lung function between different ILD types had no significant difference (P>0.05); Fifth, multivariate Logistic regression analysis showed that decreased albumin and chest tightness/shortness of breath might be the risk factor for SLE-ILD. CONCLUSION There are statistically significant differences between the SLE-ILD group and SLE non-ILD group in terms of chest tightness/shortness of breath, Velcro rale and Raynaud's phenomenon. Decreased albumin and chest tightness/shortness of breath in SLE patients should be alerted to the occurrence of ILD. NSIP is the most common manifestation of SLE-ILD.

【Objective】 To investigate whether mesenchymal stem cells （MSC）can alleviate acute lung injury by inducing alveolar macrophages to polarize to M2 phenotype. 【Methods】 Umbilical cord MSC was extracted by adherent method and cell phenotypes were analyzed by flow cytometry. The differentiation along osteogenic and adipogenic pathways were assessed by histological staining in vitro. Mouse alveolar macrophage cell line（MH- S cells）which was stimulated by LPS was isolated co-culture with MSC and MSC soluble factor inhibitor was added. We set up three groups （LPS， LPS+MSC ，and MSC inhibitor）. After being cultured for 48 hours ，the macrophage polarization was analyzed by flow cytometry and qPCR. Thirty balb/c male mice were randomly divided into control group（n = 10），ALI group（n = 10）， and ALI+MSC group（n = 10）. LPS was instilled intranasally to establish acute lung injury model in mice. After treatment with MSC for 48 hours ，HE staining of lung tissue was performed for damage assessment. The alveolar lavage fluid （BALF）was obtained and the cells in BALF were analyzed by flow cytometry and qPCR to detect the expression of M2-type macrophage markers including CD206，IL10 and Arg1. The concentration of M1-type macrophage marker TNF-α in the supernatant was measured by ELISA. 【Results】 MSC showed adherent growth and had the ability of osteogenic and adipogenic differentiation. MSC can induce MH- S cells to polarize to M2 type and with a significant increase of CD206 positive proportion cells （P<0.05）. Prostaglandin E2 （PGE2） inhibitors can reverse this effect. Mouse ALI model was successful. After treatment with MSC，the pathology and lung injury score was significantly improved. The proportion of CD206 positive macrophages in alveolar lavage fluid in ALI + MSC group was significantly higher than that in ALI group. The expression of CD206 and IL-10 in mRNA level was significantly higher in ALI+MSC group than that in ALI group. The concentration of inflammatory cytokine TNF- α in alveolar lavage fluid was significantly lower in the ALI+ MSC group than in the ALI group（P<0.05）.【Conclusion】Umbilical cord mesenchymal stem cells can effectively alleviate acute lung injury induced by LPS in mice via PEG2 to induce macrophage to polarize to M2 type.
