ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine （TCM） in clinical practice， but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad， which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix， the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison， use of poison， anti-poison， and detoxification'' were employed to mine the relevant toxicity records， usage and dosage， processing compatibility， and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included， suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity， and the adverse reactions may be related to long-term use， excessive use， and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling， steaming with black beans， and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria， Psoraleae Fructus， and Cistanches Herba. ConclusionReasonable dosage， standard processing， correct compatibility， and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically， the toxicity classification of TCM should be strengthened， and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved， and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.

Objective To study the effect of improved gastric lavage with intermittent pumping liquid at stomarch regions.Methods 110 cases poisoned by intoxication orally were randomly divided into two groups in equal number,that is to say,with an experimental group of 55 cases and a control group of 55 cases.The experimental group was treated with the improved gastric lavage with electrostomach irrigator,and the control group with traditional method.The quality of the stomach lavnging between the two groups were compared.Results In comparison of the two groups,the following differences were significant,that is,in time of lavaging and the vohmn of gastric lavage,smooth aspiration of washing-out liquid,mistakes of absorbing washing-out liquid,vomitus 1 h after lavnge,injury of gastric mucosa (for each of all,P < 0.05).Conclusions The improved gastric lavage with intermittent pumping liquid is more effective in reducing liquid,shortening lavage time,reduing gastric injury of mucous membrane,preventing mis-aspiration and avoiding the vomiting after gastric lavnge operation.

OBJECTIVETo retrospectively analyze the results of a consecutive series of 100 ALL patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) in our center.

METHODSOf the 100 ALL patients, 69 were male and 31 female, with a median age of 29.5 (4 - 47) years. Sixty-nine cases were in the first complete remission (CR(1)), 13 in more than CR(1) and 18 in relapse before transplant. Allo-HSCT from HLA identical siblings was performed for 86 patients, of whom 64 received bone marrow transplantation (BMT) and 22 peripheral blood stem cell transplantation (PBSCT). HLA matched unrelated BMT was performed for 8 patients, cord-blood transplantation from unrelated donor for 6 patients. Forty-five patients underwent allo-HSCT with conditioning regimen of Cy/TBI, 55 with BUCY. Prophylaxis of graft-versus-host disease (GVHD) included long-term MTX regimen (4 cases) and CsA + MTX regimen (96 cases). The average follow-up was 38.1 months.

RESULTSThe 5-year overall survival (OS) and disease-free survival (DFS) of the 100 cases of ALL was 53.4% and 50.5%. The 5-year OS and DFS were significantly longer for patients in CR(1) than in >CR(1) and relapse patients before allo-HSCT (P < 0.001). The outcome of PBSCT seemed superior to that of BMT, but there was no difference between them. Multivariate analysis showed the most significant factor associated with long post allo-HSCT survival was that the patient underwent transplantation in CR(1). There was no significant difference in 5-year OS, DFS, cumulative incidences of relapse rate and treatment related mortality between the two cohorts prepared with TBI or BUCY.

CONCLUSIONSAllo-HSCT can cure a significant proportion of ALL patients, especially for those in CR(1). There was no significant difference in OS, DFS between the two different conditioning regimens and the different transplant choices.
