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.

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.

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.

Discipline construction is the power source to realize the high quality development of public hospitals,and high quality scientific research management is the inevitable path to realize the connotative development of public hospitals.The quality improvement of scientific research project process management is step-by-step,and mid-term inspection is a representative work.This paper applies PDCA cycle theory to the mid-term inspection of scientific research projects,analyzes the problems encountered in the mid-term inspection of scientific research projects from the four stages of plan,implementation,check and act,and develops effective intervention measures.The mid-term inspection mode,which combines publicity activities of scientific research norms with self-examination by researchers and on-the-spot inspection by the scientific research department,should be carried out to standardize the process of mid-term inspection of scientific research projects and promote the high-quality development of scientific research in hospitals.

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.

Objective:To present the surgical details of manual double-layer suturing in patients with obesity combined type 2 diabetes mellitus by three-incision laparoscopic single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy .Methods:Clinical data and follow-up information of 52 obesity combined type 2 diabetes mellitus patients (BMI 27.59-43.71 kg/m2) who underwent three-incision laparoscopic single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy from Jan 2019 to Jul 2022 at Beijing Shijitan hospital were retrospectively analyzed.Results:The procedure was successful in all patients. The median operative time was 120 (90, 120) min, and the median intraoperative bleeding was 20.0 (10.0, 27.5) ml. No fistula or serious surgical complications were observed in the patients at 1 month postoperatively. Compared with the preoperative period, the patient's weight decreased [(93.22±15.21) kg vs. (69.97±11.06) kg, t=21.707, P<0.01], BMI decreased [(33.11±4.09) kg/m 2vs. (24.86±2.95) kg/m 2, t=23.224, P<0.01], and the patient's fasting glucose level decreased [9.52 (7.57, 12.96) mmol/L vs. 5.47 (4.66, 6.39) mmol/L, Z=6.11, P<0.01]. The remission rate of various obesity comorbidities was greatly improved. Conclusion:Under the condition of three-incision laparoscopy, the pure manual duodenal and jejunal double-layer suture method is safe, feasible, and effective for patients with obesity combined with type 2 diabetes mellitus.

As one of notable works of HUANG Yuanyu， a renowned physician from the Qing Dynasty， The Indications of Classics by Four Medical Sage emphasize the theoretical paradigm of “one qi circulation” with a particular focus on the middle qi. Building upon disease differentiation and treatment， HUANG Yuanyu attaches great importance to understanding the underlying cause of the disease. It is believed that the imbalance of the six climatic factors is the fundamental cause of diseases. The concept of mutual interaction between the physiological and pathological aspects of the six climatic factors is proposed to grasp the basic pathogenesis. Based on the individual's specific condition of six climatic factors， excess or deficiency， specific prescriptions are formulated. The diagnosis and treatment system can be summarized as a “differentiation of diseases → disease etiology → differentiation of the condition of six climatic factors → individualized pathogenesis of traditional Chinese medicine （TCM） → prescription of TCM” model based on the holistic view. HUANG Yuanyu' s diagnosis and treatment system is highly practical and can provide reference for clinical diagnosis and treatment of diseases in TCM.

Based on the theory of ascending and descending of center qi， it is believed that yang deficiency and water dampness， as well as abnormal circulation of center qi， are the core pathogenesis of psoriasis. The common pathogenic evolution of psoriasis includes wood constraint and blood stagnation， lung metal fluid exhaustion. In the later stage of psoriasis， a mixture of deficiency and excess patterns， as well as cold and heat in complexity， are often observed. Treatment focuses on warming yang and resolving dampness to restore proper qi ascending and descending， and the therapeutic formulas such as Ganjiang Lingzhu Decoction （甘姜苓术汤）， Zexie Decoction （泽泻汤）， Zhenwu Decoction （真武汤）， and Linggui Zhugan Decoction （苓桂术甘汤） are suggested based on the nature and location of the disease. To unblock the qi movement through discharging the liver and rectifying the lung， Xiaochaihu Decoction （小柴胡汤） and Danzhi Xiaoyao Powder （丹栀逍遥散） are commonly used as the foundation with modifications. To balance yin and yang through clearing the heart and nourishing the kidneys， a self-designed Changzhong Decoction （畅中汤） is utilized. Following the theory of ascending and descending of center qi， it is suggested to combine cold and warm medicinals and mediate the center earth， so as to promote the circulation of the center qi， restore the clear and the turbid， and keep four-dimensional smooth flow of qi， providing a reference for traditional Chinese medicine treatment for psoriasis.

Objective:To investigate the clinical features and prognosis of multiple myeloma(MM)patients who resisted to the combination of bortezomib,lenalidomide and dexamethasone(VRD). Methods:The clinical features and prognosis of 150 patients with newly diagnosed MM in Beijing Chaoyang Hospital who were treated with VRD from January 2015 to January 2020 were retrospectively analyzed by SPSS software. Results:Among a total of 150 MM patients,21 patients resisted to VRD,including 14 patients with primary refractory to VRD and 7 patients with early relapse.In the VRD-resistant group(n=21),the median age of patients was 58 years(37-70 years),and female patients were more common(61.9％);Durie-Salmon stage:17 patients were DS stage Ⅲ,4 patients were DS stage Ⅱ;44.4％of those patients were cytogenetic high risk.CD20 positive rate was higher in the VRD-resistant group(P=0.014).The overall survival(OS)of MM patients in the VRD-resistant group was significantly lower than that in the VRD-nonresistant group(34 months vs not achieved,P＜0.001).In the VRD-resistant group,the median OS of MM patients receiving autologous hematopoietic stem cell transplantation was significantly longer than that of non-transplant patients(34 months vs 16 months,P=0.038).Drug resistance and non-autologous transplantation are independent adverse prognostic factors for newly diagnosed MM patients receiving VRD induction chemotherapy.COX multivariate analysis showed that age＞65,cytogenetic high risk and non-autologous stem cell transplantation may be adverse prognostic factors for VRD-resistant MM patients. Conclusion:Positive CD20 was more common in MM patients with VRD resistence,which may indicate more aggressive biological characteristics in VRD-resistent MM patients.The VRD-resistent MM patients had poor prognosis,they can obtain disease remission from salvage chemotherapy including daratumumab,and the survival of them also can be improved after autologous stem cell transplantation.
