ObjectiveTo investigate the feasibility， safety， and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt （SA-TIPS） in the treatment of portal hypertension comorbid with complex portal vein thrombosis， including cavernous transformation of the portal vein （CTPV）. MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital， Capital Medical University， from November 2023 to January 2025， including general status， technical data of the surgical process （surgical success rate， puncture times， time of operation， the number of stents used， and the length of shunt）， perioperative complications， and surgical recovery. The change in portal pressure gradient （PPG） after shunt was compared， and the rate of reaching the standard for PPG reduction was calculated， as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients， 34 （94.4%） underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% （6/36）， including 3 cases of thoraco-abdominal hemorrhage， 2 cases of intraoperative arrhythmia， and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS （t=19.85， P<0.01）， and the patients achieving a ≥50% reduction in PPG accounted for 76.5% （26/34）. Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate， a favorable safety profile， and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis （including CTPV）， and therefore， it holds promise for clinical application.

Objective:To analyze the clinical characteristics and identify predictive factors for spontaneous passage of common bile duct (CBD) stones.Methods:A retrospective analysis was conducted on patients diagnosed as having choledocholithiasis via abdominal imaging at outpatient and emergency departments of Jiangsu Province Hospital of Chinese Medicine and other medical institutions from January 2021 to November 2023. Participants were stratified into spontaneous passage versus non-passage groups. Multivariate logistic regression analysis was used to identify predictors for the spontaneous passage of common bile duct stones.Results:Spontaneous stone passage were confirmed in 70 cases (15.5%). Multivariate logistic regression analysis identified that an admission diagnosis of acute biliary pancreatitis ( OR=3.317, 95% CI: 1.427-7.713, P=0.005), larger common bile duct diameter ( OR=1.117, 95% CI: 1.000-1.248, P=0.049), and solitary stones ( OR=11.135, 95% CI: 3.602-34.418, P<0.001) significantly increased the probability of spontaneous stones. In contrast, larger stone long diameter ( OR=0.539, 95% CI: 0.441-0.659, P<0.001) markedly decreased passage likelihood. Receiver operator characteristic (ROC) curve analysis demonstrated that the common bile duct diameter predicted spontaneous stone passage with an area under the curve (AUC) of 0.662, yielding sensitivity of 52.9% (37/70) and specificity of 73.6% (51/70) at a cutoff value of 9.5 mm. The common bile duct stone diameter achieved an AUC of 0.852 for predicting spontaneous stone passage, with sensitivity of 75.7% (53/70) and specificity of 89.0% (62/70) at a cutoff value of 4.5 mm. Conclusion:Solitary small stones, ductal dilation, and an admission diagnosis of acute biliary pancreatitis are key predictive factors for spontaneous common bile duct stone passage. A common bile duct diameter ≥9.5 mm and stone long diameter ≤4.5 mm are more likely to result in spontaneous stone passage.

Objective:To investigate the relationship between changes in total plasma bile acid (TBA) levels and the remission of non-alcoholic fatty liver disease (NAFLD) in patients with obesity after laparoscopic sleeve gastrectomy (LSG).Methods:A retrospective analysis was conducted on clinical data and follow-up information of 20 patients with obesity and NAFLD undergoing LSG in Beijing Shijitan Hospital between Mar to Jun 2022.Results:Postoperative weight loss was significant. Compared to preoperative values, the weight of 20 patients decreased [(115.92±16.13) kg vs. (78.20±7.77) kg, t=15.675, P<0.001]. The BMI also decreased [(40.66±5.18) kg/m2 vs. (27.43±2.22) kg/m2, t=13.230, P<0.001]. The fatty liver index and hepatic steatosis index decreased significantly [(96.34±5.23) vs. (27.96±20.36), t=16.829, P<0.001; (55.15±6.73) vs. (37.55±4.30), t=16.294, P<0.001]. Plasma TBA levels significantly increased [(7.06±2.80) vs. (12.27±3.79) μmol/L, P<0.001]. Indicators related to glucose, lipids, and liver function in patients significantly decreased. Conclusions:LSG can significantly reduce body weight in patients with obesity and NAFLD and improve NAFLD. LSG can increase plasma TBA levels, and the elevation in TBA levels is positively correlated with the degree of NAFLD remission.

Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.

Background::The effect of bariatric surgery on type 2 diabetes mellitus (T2DM) control can be assessed based on predictive models of T2DM remission. Various models have been externally verified internationally. However, long-term validated results after laparoscopic sleeve gastrectomy (LSG) surgery are lacking. The best model for the Chinese population is also unknown.Methods::We retrospectively analyzed Chinese population data 5 years after LSG at Beijing Shijitan Hospital in China between March 2009 and December 2016. The independent t-test, Mann–Whitney U test, and chi-squared test were used to compare characteristics between T2DM remission and non-remission groups. We evaluated the predictive efficacy of each model for longterm T2DM remission after LSG by calculating the area under the curve (AUC), sensitivity, specificity, Youden index, positive predictive value (PPV), negative predictive value (NPV), and predicted-to-observed ratio, and performed calibration using Hosmer–Lemeshow test for 11 prediction models. Results::We enrolled 108 patients, including 44 (40.7%) men, with a mean age of 35.5 years. The mean body mass index was 40.3 ± 9.1 kg/m 2, the percentage of excess weight loss (%EWL) was (75.9 ± 30.4)%, and the percentage of total weight loss (% TWL) was (29.1 ± 10.6)%. The mean glycated hemoglobin A1c (HbA1c) level was (7.3 ± 1.8)% preoperatively and decreased to (5.9 ± 1.0)% 5 years after LSG. The 5-year postoperative complete and partial remission rates of T2DM were 50.9% [55/108] and 27.8% [30/108], respectively. Six models, i.e., "ABCD", individualized metabolic surgery (IMS), advanced-DiaRem, DiaBetter, Dixon et al’s regression model, and Panunzi et al’s regression model, showed a good discrimination ability (all AUC >0.8). The "ABCD" (sensitivity, 74%; specificity, 80%; AUC, 0.82 [95% confidence interval [CI]: 0.74–0.89]), IMS (sensitivity, 78%; specificity, 84%; AUC, 0.82 [95% CI: 0.73–0.89]), and Panunzi et al’s regression models (sensitivity, 78%; specificity, 91%; AUC, 0.86 [95% CI: 0.78–0.92]) showed good discernibility. In the Hosmer–Lemeshow goodness-of-fit test, except for DiaRem ( P <0.01), DiaBetter ( P <0.01), Hayes et al ( P = 0.03), Park et al ( P = 0.02), and Ramos-Levi et al’s ( P <0.01) models, all models had a satifactory fit results ( P >0.05). The P values of calibration results of the "ABCD" and IMS were 0.07 and 0.14, respectively. The predicted-to-observed ratios of the "ABCD" and IMS were 0.87 and 0.89, respectively. Conclusion::The prediction model IMS was recommended for clinical use because of excellent predictive performance, good statistical test results, and simple and practical design features.

Objective To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022, so as to provide insights into formulation of echinococcosis control measures in the prefecture. Methods Villagers were randomly sampled using a multistage sampling method from class I and II echinococcosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococcosis, while all patients undergoing ultrasound examinations in medical institutions in class III endemic counties received active echinococcosis screening. In addition, livestock in centralized slaughterhouses or slaughtering sites were screened for echinococcosis using the palpation and necropsy method, and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs. The trends in detection of human and livestock echinococcosis, detection of newly diagnosed human echinococcosis cases and detection of Echinococcus coproantigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022. Results The mean detection rate of human echinococcosis was 0.13% (540/407 803) in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022, which appeared a tendency towards a decline over years (χ²_trend = 1 217.21, P < 0.001), and the highest detection of newly diagnosed echinococcosis cases was seen in Hejing County (0.28%, 191/67 865). The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 147.02, P < 0.001), with the highest detection rate seen in Hejing County (3.44%, 86/2 500), and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022 (χ²_trend = 302.46, P < 0.001), with the highest detection rate in Qiemo County (2.74%, 118/4 313). Conclusions The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022; however, there is still a high echinococcosis transmission risk in local areas. Sustainable integrated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.

This paper summarized the experience of fire needling combined with black cloth ointment in the treatment of keloid. In terms of the pathogenesis of keloid， it is believed that "phlegm causes stasis， and then stasis accumulates into tumors" is the key； the internal obstruction of phlegm and stasis caused by insufficient endowment and invasion of external pathogens is the root of the disease， while the endogenous generation of phlegm and dampness is the branch. It is therefore proposed to explore the etiology and pathogenesis of keloid from the perspective of "phlegm-stasis-tumor"， and the treatment principle is mainly to eliminate phlegm， dispel stasis and dissolve tumors， supplemented with heat-clearing and toxin-resolving. Treatment methods include oral administration of Chinese herbal medicinals and external treatment. Self-made formula for keloid is taken orally， with the main functions of dissolving phlegm， dispelling stasis and clearing heat， to finally dissolve the tumors. For external treatment， fire needling is used to pierce the skin and to open the striae and interstices， and force out the toxin pathogens such as phlegm-heat and stasis-heat with fire power， thereby clearing heat， dissolving phlegm， dispelling stasis and resolving toxins. Black cloth ointment can be used to the affected area to unblock meridians and collaterals， clear heat-toxin and dissolve phlegm-stasis， thereby softening hardness and dissipating masses.

Objective:To explore the prognostic factors of primary plasma cell leukemia (pPCL) in the era of novel agents.Methods:The clinical data of 66 patients with pPCL treated at the Department of Haematology, Beijing Chao-Yang Hospital, Capital Medical University from 2011 to 2022 were retrospectively collected to analyze their prognostic factors.Results:Among the 66 patients with pPCL, the median age was 59 (range: 29-79) years. The median overall survival (OS) duration was 19.0 (95% CI 10.4-27.6) months, and the median progression-free survival (PFS) duration was 11.0 (95% CI 6.5-15.6) months. The median OS and PFS were significantly longer in patients with the best post-treatment response of very good partial remission (VGPR) or better than in patients with a response of partial remission (PR) or worse (median OS: 33.0 months vs 6.0 months, P<0.001; median PFS: 16.0 months vs 3.0 months, P<0.001). OS was significantly longer in patients who underwent autologous hematopoietic stem cell transplantation than in those who did not undergo transplantation (49.0 months vs 6.0 months, P=0.002), and there was a trend toward a longer PFS in patients who underwent transplantation than in those who did not undergo transplantation (19.0 months vs 8.0 months, P=0.299). The median OS and PFS were significantly longer in patients who received maintenance therapy than in those who did not receive maintenance therapy (median OS: 56.0 months vs 4.0 months, P<0.001; median PFS: 20.0 months vs 2.0 months, P<0.001). Multivariate analysis showed that hypercalcemia was an independent risk factor ( HR=3.204, 95% CI 1.068-9.610, P=0.038) for patients with pPCL, while receiving maintenance therapy ( HR=0.075, 95% CI 0.022-0.253, P<0.001) and post-treatment response of VGPR or better ( HR=0.175, 95% CI 0.048-0.638, P=0.008) were independent protective factors for patients with pPCL. Conclusions:In the era of novel agents, hypercalcemia, receiving maintenance therapy, and post-treatment response of VGPR or better are independent prognostic factors for pPCL.
