Objective:To evaluate the effect of cognitive behavioral therapy (CBT) on reducing anxiety and promoting rapid postoperative recovery in patients undergoing induced abortion surgery.Methods:Non-randomized controlled trials were adopted, a total of 480 patients scheduled for induced abortion between January 2024 and January 2025 were consecutively enrolled and allocated to the intervention group ( n=240) or control group ( n=240). The control group received conventional education, whereas the intervention group implemented cognitive behavioral therapy on the basis of control group. The Hamilton anxiety scale (HAMA), the self-rating anxiety scale (SAS) and the 36-item short-form health survey (SF-36) were the main observed outcome measures. The anxiety, pain degree 24 h after the intervention, postoperative recovery, postoperative complications and changes in quality of life after the intervention were compared between the two groups of patients. Taking the baseline characteristics of the patients as independent variables and the scores of HAMA, SAS and SF-36 as dependent variables, multiple linear regression analysis was conducted. Results:After the intervention, the scores of HAMA and SAS in the intervention group were 5.76±1.13 and 40.98±3.76 respectively, which were lower than those in control group (7.08±1.42; 46.42±4.14), and the differences were statistically significant (all P<0.001). The score of the visual analogue scale 24 h after the operation was lower than that in control group (1.64±0.48 vs. 2.83±0.76), and the difference was statistically significant ( P<0.001). The duration of vaginal bleeding, the time of menstrual resumption and the recovery time of daily activities in the intervention group were all shorter than those in control group [(8.23±2.36) d vs. (10.87±2.16) d; (28.34±3.65) d vs. (33.47±4.18) d; (18.98±5.24) d vs. (25.42±4.16) d], and the differences were statistically significant (all P<0.001). Six weeks after the operation, the total incidence of complications in the intervention group was 5.0% (12/240), which was lower than that in control group [12.9% (31/240)], and the difference was statistically significant ( P=0.002). After the intervention, the total score of each dimension of SF-36 was higher than that in control group (334.68±5.79 vs. 305.46±5.93), and the difference was statistically significant ( P<0.001). Multiple linear regression analysis showed that higher educational attainment (bachelor's degree and above compared with junior high school and below HAMA β=-0.52, 95% CI: -0.85--0.19, P=0.002; SAS β=-0.75, 95% CI: -1.31--0.19, P=0.008) and higher household income (HAMA β=-0.15, 95% CI: -0.22--0.08, P<0.001; SAS β=-0.18, 95% CI: -0.28--0.08, P<0.001) were protective factors for reducing anxiety levels. Married was the protection factor in SAS scores ( β=-0.68, 95% CI: -1.22--0.14, P=0.013), and higher number of pregnancies was a risk factor for SAS scores ( β=0.19, 95% CI: 0.07-0.31, P=0.002). Age increase was a protective factor for HAMA score ( β=-0.03, 95% CI: -0.05--0.01, P=0.001). Higher educational attainment (junior college: β=3.25, 95% CI: 0.60-5.90, P=0.016; bachelor's degree and above: β=5.02, 95% CI: 2.33-7.71, P<0.001), higher household income ( β=1.25, 95% CI: 0.55-1.95, P<0.001), and married status ( β=2.81, 95% CI:0.28-5.34, P=0.030) were all significant positive predictors of quality of life. Conclusion:Cognitive-behavioral therapy effectively alleviates anxiety, reduces post-operative complications, accelerates recovery, and improves the quality of life in women undergoing induced abortion.

Objective:To investigate the effects of ginsenoside Compound K (CK) on proliferation, apoptosis, and autophagy in gastric cancer cells, and to further explore whether it exerts its effects by regulating the AMPK/mTOR signaling pathway.Methods:Human gastric cancer AGS cells were cultured in vitro to the logarithmic growth phase and randomly divided into control group (treated with 0.9% sodium chloride solution), ginsenoside CK group (treated with 50 μM CK) and ginsenoside CK+ Dorsomorphin group (treated with 50 μM CK combined with 10 μM Dorsomorphin). AGS cells were treated with ginsenoside CK at concentrations of 0, 5, 10, 20, 50, 100, and 200 μM, and cell viability was measured by the CCK-8 assay to determine the optimal concentration (50 μM). After treatment according to the above groups, cell viability was assessed by the CCK-8 assay; colony formation was evaluated by the plate clone formation assay; apoptosis was detected by the Tunel assay; autophagy was assessed by MDC fluorescence staining; and the expression levels and phosphorylation status of autophagy-related proteins (Beclin-1, LC3-Ⅱ), apoptosis-related proteins (Caspase-3, Bax, Bcl-2), and AMPK/mTOR signaling pathway-related proteins were analyzed by Western Blot. Statistical analysis of the data was performed using GraphPad Prism 9.1.2 software.Results:Compared with the control group, the apoptosis rate, autophagy degree and the expression levels of Beclin-1, LC3-Ⅱ, caspase-3, Bax and p-AMPK proteins were significantly increased in the ginsenoside CK group ( P<0.05), while the cell viability, clone formation rate, and the expression levels of Bcl-2 and p-mTOR proteins were decreased ( P<0.05). After the addition of AMPK pathway inhibitor Dorsomorphin based on 50 μM ginsenoside CK treatment, the apoptosis rate, the degree of autophagy, and the expression levels of Beclin-1, LC3-Ⅱ caspase-3, Bax, and p-AMPK proteins showed a decreasing tendency ( P<0.05). In contrast, the cell viability, the clone formation rate, and the expression levels of Bcl-2 and p -mTOR protein expression levels showed a certain rebound trend ( P<0.05). The anti-tumor effect of ginsenoside CK was reversed by the combined intervention of ginsenoside CK and dorsomorphin in AGS cells. Conclusion:Ginsenoside CK suppresses gastric cancer cell proliferation while enhancing apoptosis and autophagy through modulation of the AMPK/mTOR signaling pathway, offering a promising novel approach for gastric cancer therapy.

Objective:To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) after pancreaticoduodenectomy and endoscopic selection strategies.Methods:Clinical data of 34 patients treated with ERCP after pancreaticoduodenectomy at the Endoscopic Center of the First Affiliated Hospital of Air Force Medical University from January 2013 to December 2021 were retrospectively analyzed. The success rates of endoscopic insertion, diagnosis, treatment and ERCP, and the incidence of adverse events were analyzed.Results:Fifty ERCP treatments were performed in 34 patients. The success rates of endoscopic insertion, diagnosis, treatment, and ERCP after pancreaticoduodenectomy were 92.0% (46/50), 93.5% (43/46), 88.4% (38/43) and 76.0% (38/50), respectively. The success rates of ERCP assisted with colonoscope and balloon-assisted enterosocpe were 76.0% (19/25) and 75.0% (18/24), respectively. There were 3 adverse events, including 1 case of anastomotic mucosa tear during surgery, 1 case of cardiopulmonary arrest and 1 case of postoperative cholangitis.Conclusion:ERCP is effective and safe after pancreaticoduodenectomy in general. ERCP assisted with colonoscope and balloon-assisted colonoscope shows similar success rate after pancreaticoduodenectomy.

Endocrine-resistance remains a major challenge in estrogen receptor α positive (ERα⁺) breast cancer (BC) treatment and constitutively active somatic mutations in ERα are a common mechanism. There is an urgent need to develop novel drugs with new mode of mechanism to fight endocrine-resistance. Given aberrant ERα activity, we herein report the identification of novel covalent selective estrogen receptor degraders (cSERDs) possessing the advantages of both covalent and degradation strategies. A highly potent cSERD 29c was identified with superior anti-proliferative activity than fulvestrant against a panel of ERα⁺ breast cancer cell lines including mutant ERα. Crystal structure of ERα‒ 29c complex alongside intact mass spectrometry revealed that 29c disrupted ERα protein homeostasis through covalent targeting C530 and strong hydrophobic interaction collied on H11, thus enforcing a unique antagonist conformation and driving the ERα degradation. These significant effects of the cSERD on ERα homeostasis, unlike typical ERα degraders that occur directly via long side chains perturbing the morphology of H12, demonstrating a distinct mechanism of action (MoA). In vivo, 29c showed potent antitumor activity in MCF-7 tumor xenograft models and low toxicity. This proof-of-principle study verifies that novel cSERDs offering new opportunities for the development of innovative therapies for endocrine-resistant BC.

Objective:To study the effect of duodenal papillary morphology on selective biliary cannulation (SBC).Methods:Data of 912 patients with biliopancreatic diseases treated with endoscopic retrograde cholangiopancreatography (ERCP) at the Department of Gastroenterology, Affiliated Hospital of Northwest Minzu University from January 2018 to January 2020 were retrospectively analyzed. Duodenal papillary morphology of patients was classified into 4 types by using Haraldsson's endoscopic classification. The success rate of SBC, the pre-incision rate, the difficult intubation rate and the incidence of post-ERCP pancreatitis (PEP) of different papillary types were analyzed.Results:A total of 912 patients were enrolled in this study, and 86.95% (793/912) duodenal papilla conformed to one type of the classification, of which 77.18% (612/793) were regular type (type Ⅰ), 10.21% (81/793) small nipple type (type Ⅱ), 8.58% (68/793) protruding or drooping type (type Ⅲ), and 4.04% (32/793) wrinkled or ridged type (type Ⅳ). The success rates of SBC in four types of duodenal papilla were 98.86% (605/612), 90.12% (73/81), 88.24% (60/68) and 96.60% (28/32) respectively. The success rate of SBC of type Ⅰ was higher than those of type Ⅱ-Ⅳ (all P<0.008) and there was no significant difference between those of type Ⅱ and type Ⅲ ( P> 0.008). The pre-incision rate in the four types of duodenal papilla were 7.84% (48/612), 32.10% (26/81), 50.00% (34/68) and 25.00% (8/32) respectively. The pre-incision rate of type Ⅰ was lower than those of type Ⅱ-Ⅳ (all P<0.008), and there was no significant difference between those of type Ⅱ and type Ⅲ ( P>0.008). The difficult intubation rate in the four types of duodenal papilla were 12.42% (76/612), 39.51% (32/81), 58.82% (40/68) and 28.12% (9/32) respectively .The difficult intubation rate of type Ⅰ was lower than those of type Ⅱ and type Ⅲ (both P<0.001), and that of type Ⅲ was higher than that of type Ⅳ ( P=0.004) . There was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). The incidences of PEP of the four types were 2.61% (16/612), 12.35% (10/81), 5.88% (4/68) and 6.25% (2/32) respectively. The incidences of PEP of type Ⅱ was higher than that of type Ⅰ ( P<0.001) , and there was no significant difference between those of type Ⅰ and type Ⅳ or type Ⅱ and type Ⅲ (both P>0.008). Conclusion:SBC is affected by duodenal papilla morphology, easiest for type Ⅰ and hard for type Ⅱ and Ⅲ. Attention should be paid to risk of PEP in SBC of type Ⅱ.
