ObjectiveTo objectively evaluate the clinical efficacy of multiple therapies of traditional Chinese medicine （TCM） in low-prognosis patients who received antagonist protocol for in vitro fertilization and embryo transfer （IVF-ET） again. MethodA total of 128 patients with kidney Yin deficiency， liver depression， and blood stasis who planned to receive antagonist protocol for IVF-ET in the West China Second Hospital of Sichuan University were enrolled and assigned into two groups by random number table method. The observation group （64 casces） was treated by oral administration of Chinese medicine decoction + enema of kidney-tonifying and blood-activating method + auricular point sticking + oral administration of dehydroepiandrosterone （DHEA）， while the control group （64 casces） was treated by only oral administration of DHEA. After treatment for three menstrual cycles， both groups received the antagonist protocol for IVF-ET. The TCM syndrome scores， basic sex hormone levels， antral follicle count （AFC）， the usage of gonadotropin （Gn）， endometrial receptivity indicators， embryo quality indicators， and pregnancy outcomes were compared between the two groups. ResultAfter treatment， the observation group showed decreased follicle-stimulating hormone （FSH）/luteinizing hormone （LH） ratio， lowered level of estradiol （E₂）， increased AFC， decreased amount and days of Gn usage， improved endometrial receptivity indicators （endometrial thickness on trigger and ET days， proportion of endometrial type A in endometrial types and the level of E₂ on trigger day） and embryo quality indicators （the rates of mature follicles， fertilization， normal fertilization， and premium embryos）， and decreased TCM syndrome scores （P<0.05， P<0.01）. Moreover， the observation group had lower FSH/LH ratio， E₂ level， and amount of Gn usage， higher AFC， poorer endometrial receptivity and embryo quality indicators， and lower TCM syndrome scores than the control group after treatment （P<0.05， P<0.01）. In addition， except for 3 cases of natural pregnancy， the observation group outperformed the control group in terms of improving the clinical pregnancy rates during initiation cycle and transplantation cycle and clinical pregnancy rate and decreasing biochemical pregnancy rate and early abortion rate （P<0.05）. ConclusionCombined therapies of TCM can alleviate the clinical symptoms， reduce TCM syndrome scores， reduce the Gn usage amount， improve the number and quality of embryos and endometrial receptivity， and coordinate the synchronous development of endometrium and embryo. In this way， they can increase the clinical pregnancy rate and reduce biochemical pregnancy rate and early abortion rate in the low prognosis patients with kidney yin deficiency， liver depression， and blood stasis who are undergoing IVF-ET again.

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine （TCM） multi-channel intervention on the ovarian function，TCM syndromes and natural conception of poor ovarian responders（kidney-Yin deficiency，liver depression and blood stasis pattern） who planned to receive another in vitro fertilization embryo transfer（IVF-ET）antagonist regimen. MethodThe 128 low-prognosis patients （kidney Yin deficiency，liver depression and blood stasis pattern） who attended the West China Second University Hospital， Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected，and then divided into the treatment group and the control group according to the random number table，with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone（DHEA），while the treatment group was treated with multi-channel TCM（oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema）. After 3 menstrual cycles，the relevant indicators for ovarian function evaluation，TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment，the basal follicle stimulating hormone（bFSH），bFSH/basal luteinizing hormone（bLH），basal estradiol（bE₂），antral follicle count（AFC），the number of oocytes obtained，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment（P<0.05，P<0.01）. For the control group， the bFSH/bLH and TCM syndrome scores were increased after treatment（P<0.05）， while the bFSH，bFSH/bLH，bE₂，AFC，the number of oocytes obtained，the number of normal fertilization，and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment，bFSH，bFSH/bLH，bE₂，AFC，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were better （P<0.05，P<0.01），while there was no significant difference in the number of oocytes obtained. After treatment，there were 3 cases of natural conception in the treatment group，while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency，liver depression and blood stasis pattern，multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH，bFSH/bLH values，improve the levels of bE₂，increase AFC，the number of oocytes obtained，the number of normal fertilization and the number of superior embryos，improve ovarian function，menstruation and TCM syndromes，improve their quality of life，and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

Objective:To analyze the epidemiological characteristics and economic burden of palmoplantar pustulosis (PPP) in China.Methods:A population-based retrospective study was conducted using the data from China′s Urban Basic Medical Insurance data from January 1, 2012, to December 31, 2016.

Objective:To construct an intelligent performance measurement system of gastrointestinal endoscopy and to analyze its value for endoscopic quality improvement.Methods:The intelligent gastrointestinal endoscopy performance measurement system was developed by using the deep convolutional neural network (DCNN) and deep reinforcement learning, based on the Digital Imaging and Communications in Medicine. Images were acquired of patients undergoing gastrointestinal endoscopy at Digestive Endoscopy Center of Renmin Hospital of Wuhan University from December 2016 to October 2018. The system applied cecum recognition model (DCNN1), images in vitro and in vivo recognition model (DCNN2), and identification model at 26 gastric sites (DCNN3) to monitor indices such as cecal intubation rate, colonoscopic withdrawal time, gastroscopic inspection time, and gastroscopic coverage. Images of 83 gastroscopies and 205 colonoscopies acquired at Digestive Endoscopy Center of Renmin Hospital of Wuhan University from March to November 2019 were randomly selected to examine the effectiveness of the system. Results:The intelligent gastrointestinal endoscopy performance measurement system consisted of quality analysis of both gastroscopy and colonoscopy, including all indices, and could be generated automatically at any time. The accuracy for cecal intubation rate, colonoscopic withdrawal time, gastroscopic inspection time, and gastroscopic coverage were 92.5% (172/186), 91.7% (188/205), 100.0% (83/83), 89.3% (1 928/2 158), respectively.Conclusion:The intelligent performance measurement system for gastrointestinal endoscopy can be recommended for the quality control of gastrointestinal endoscopy, from which endoscopists can get feedback and improve the quality of gastrointestinal endoscopy.

Objective:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells (MSCs) on psoriasis-like mouse models induced by imiquimod and the underlying mechanisms.Methods:Eighteen C57BL/6 mice were randomly and equally divided into vaseline group, model group and treatment group according to a random number table. The mice in the model group and treatment group received topical treatment with 5% imiquimod cream at a dose of 62.5 mg once a day for 6 consecutive days on the shaved back, and those in the vaseline group received the treatment with the same amount of vaseline ointment; the mice in the treatment group were injected with 1.5×10 6 human umbilical cord MSCs via the caudal vein on days 1 and 4. The severity of skin lesions on the back of the mice was assessed everyday according to the psoriasis area and severity index (PASI) . Twenty-four hours after the last treatment, that is, on day 7, blood samples were taken, and the mice were sacrificed. The dorsal skin tissues were resected and subjected to hematoxylin and eosin (HE) staining. A single cell suspension of the resected spleen was prepared, and flow cytometry was performed to detect the Th1 and Th17 cell subsets in the spleen cells. Enzyme-linked immunosorbent assay was conducted to detect serum levels of cytokines interleukin (IL) -17A and tumor necrosis factor (TNF) -α. One-way analysis of variance was used for comparisons among groups, Tukey test for multiple comparisons, and repeated measures analysis of variance for the analysis of changes in the PASI score over time. Results:On day 7, there was obvious scaly erythema on the back of the mice in the model group, and the skin thickness and number of infiltrating inflammatory cells were significantly higher in the model group (78.73 ± 23.11 μm, 36.16 ± 2.95 cells/mm 2) than in the vaseline group (13.28 ± 4.57 μm, 13.33 ± 1.15 cells/mm 2, q=19.25, 7.21, respectively, both P < 0.001) . The treatment group showed significantly decreased PASI score, epidermal thickness and number of infiltrating inflammatory cells compared with the model group (all P < 0.001) . The percentage of Th17 cell subsets in the spleen cells and serum level of TNF-α were significantly lower in the treatment group than in the model group (both P < 0.05) . There were no significant differences in the spleen weight, spleen index, spleen cell count, Th1 cell percentage or serum IL-17A level between the treatment group and the model group (all P>0.05) . Conclusion:Human umbilical cord MSCs can effectively alleviate skin inflammation induced by imiquimod in the psoriasis-like mouse models, likely by inhibiting Th17 cell formation and TNF-α expression.

Objective:To investigate the effects of triptolide (TPL) and BET protein inhibitor JQ1 on proliferation inhibition and apoptosis induction of MLL-rearranged acute myeloid leukemia (AML) cell line MV4-11, and to explore their synergistic mechanisms.Methods:MV4-11 cells in logarithmic growth phase were treated with different concentrations (100, 200, 300, and 400 nmol/L) of JQ1, 4 nmol/L TPL or different concentrations of JQ1 combined with 4 nmol/L TPL for 48 h. Cell proliferation was detected by CCK-8 method, apoptosis was detected by flow cytometry (FCM), mitochondrial membrane potential was detected by JC-1 method, and expressions of mitochondrial apoptosis pathway-related proteins were detected by Western blot.Results:The 50% inhibitory concentration ( IC50) value of MV4-11 cells treated with JQ1 for 48 h was (283.9±10.7) nmol/L. However, 4 nmol/L TPL significantly enhanced the inhibitory effect of JQ1 on proliferation of MV4-11 cells, the IC50 value of MV4-11 cells treated with JQ1 combined with TPL was (148.1±2.6) nmol/L, and the difference was statistically significant ( t = 25.31, P = 0.029). The result of FCM assay showed that compared with the JQ1 alone group [(9.6±2.3)%, (12.6±1.4)%, (19.5±3.3)%, and (22.7±2.1)%], 4 nmol/L TPL combined with different concentrations (100, 200, 300, and 400 nmol/L) of JQ1 acted on MV4-11 cells for 48 h, the proportions of apoptotic cells were (16.4±1.9)%, (27.5±2.1)%, (32.9±3.6)%, and (35.5±3.0)%, respectively, the difference was statistically significant ( F = 9.25, P < 0.01). After treated with 4 nmol/L TPL and JQ1 for 12 h, the level of cell membrane potential in MV4-11 cells was significantly lower than that of JQ1 single agent group, and the difference was statistically significant ( P < 0.05). After treated by 4 nmol/L TPL combined with JQ1 for 24 h, the levels of anti-apoptotic proteins bcl-2 and Mcl-1 decreased, and the level of pro-apoptotic protein bax increased. Conclusion:TPL can significantly enhance the proliferation inhibition and apoptosis induction effects of BET protein inhibitor JQ1 on MLL-rearranged AML cells, and the mechanism may be related to enhancing the mitochondrial apoptosis pathway.

Objective To evaluate the a.ccuracy of ultrasound in verifying endotracheal tube (ETT) position in neonates.Methods Sixty neonates of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 2-28 days,weighing 2.5-4.8 kg,scheduled for urachal fistula/urachal resection or inguinal hernia repair under general anesthesia,were divided into 2 groups (n=30 each)using a random number table method:auscultation group and ultrasound group.Confirmation of ETF position was performed in two stages.In the first stage,misplacement of ETT into esophagus was identified using auscultation and ultrasound techniques after intubation,and end-tidal carbon dioxide pressure was considered as the gold standard for identification of esophageal intubation.In the second stage,misplacement of ETY into bronchus was identified using auscultation and ultrasound after confirming ETT position was within the trachea,and electronic bronchoscope served as the gold standard for identification of bronchial intubation.Results Compared with auscultation group,the accurate rate of identification of bronchial intubation was significantly increased in ultrasound group (P＜0.05).The sensitivity,specificity,positive predictive value (PPV) and negative predictive value (NPV) of auscultation for identification of esophageal intubation was 100％,96.3％,75％ and 100％,respectively.The sensitivity,specificity,PPV and NPV of auscultation for identification of bronchial intubation was 33.3％,95.8％,66.7％ and 85.2％,respectively.The sensitivity,specificity,PPV and NPV of ultrasound for identification of esophageal or bronchial intubation were all 100％.Conclusion Ultrasound can verify ETT position accurately in neonates.

To investigate the induction of cell cycle arrest of human breast cancer MDA-MB231 cells by Di-indolyl pyrrolidine(DIPRD), a pyrrolidine-derived spirooxindoles compounds. The cytotoxic effect of DIPRD on MDA-MB231 cells was detected by CCK-8 method. The cell cycle arrest of MDA-MB231 cells was detected by DAPI/EdU double-staining. Phosphorylation levels of AKT, mTOR, apoptosis-related proteins p53, MDM2, and DNA repair enzyme PARP levels were detected by Western blot. DIPRD inhibited the viability of MDA-MB231 cells by downregulating the number of EdU-positive cells, increase G1 phase and reduce cell number in S/G2 phase, down-regulated the p-AKT(Ser473), p-mTOR, p-p53, cyclin D1, CDK4, and the upregulated the p-AKT(Thr308), p-MDM2 and Cleaved-PARP levels were detected in a dose-dependent manner at 12. 5, 25, and 50 mg/mL. DIPRD may play a role in cell cycle arrest through AKT signaling pathway and induce cell apoptosis.
