Objective To study the effect of recombinant interlukin-2 plus chemotherapy in treatment of multiple myeloma. Methods We divided into two groups: chemotherapy plus rIL-2 group and simple chemotherapy group. The patients were given at dose of rIL-2 1×l06 IU/d, iH, qd, for 4 weeks and 4cycles. After 4 cycles the changes of T-cell subsets of their peripheral blood were determined. Response was evaluated according to Blad criteria. Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria,version 3.0. Results The positive percentages of CD_3, CD_4 NK, CD_(69) and CD_4/CD_8ratio after chemotherapy in chemotherapy plus rIL-2 group were significantly higher than those before chemotherapy in the same group and those after chemotherapy in the other group. The overall response rate and complete response rate were 66.7 % and 25.0 % vs 50.0 % and 8.3 % respectively. The side effects of rIL-2 were predictable and manageable. Conclusion Recombinant interlukin-2 plus chemotherapy could increase immune function of patients with multiple myeloma and has a higher response rate as compared with simple chemotherapy.

Objective To evaluate the effects of thalidomide in combination with dexamethasone (ID) in patients with relapsed or refractory multiple myeloma and in patients on stable phase. Methods Sixty-two patients with multiple myeloma were studied, include 25 with relapsed or refractory multiple myeloma, and 37 in stable phase. For the relapsed or refractory patients, thalidomide and dexamethasone was given at first three cycles, and then other regiments were given to no-response patients. For the all response patients, the second three cycles TD were enforced. On stable phase patients, thalidomide and dexamethasone were given as the second three cycles of relapsed or refractory patients. Then, thalidomide was given persistently until the disease relapse. Results All of the 25 relapsed or refractory patients were accepted the first 3 cycle TD treatment. The total response rate (VGPR+PR+MR) was 80 %. No complete remission (CR) and near CR(nCR) was gained. For the all response patients, the second three cycles TD were enforced. One patient achieved nCR. Thalidomide was given to all response patients. The median remission time was 6.8 (4~12) months. TD regimen was used to the 37 stable phase patients. The median remission time was 17.5 (8~26) months. The remission time of stable remission patients is longer then that of relapsed or refractory patients (P <0.001). Conclusion The combination of thalidomide and dexamethasone is a feasible and active regimen in the treatment of relapsed or refractory, and stable phase myeloma patients.

Objective: This study investigated the efficacy and safety of a combination of lenalidomide, bortezomib, and dexametha-sone (RVD) in patients with newly diagnosed multiple myeloma (NDMM). Methods: The clinical features and responses of 48 patients with NDMM who were treated with RVD from January 2015 to May 2019 in Beijing Chaoyang Hospital were retrospectively analyzed. Results: The median age of the 48 patients was 59 years (range: 34-79). Among these, 44 patients were Durie-Salmon stageⅢ, 15 were ISS stageⅡ, 19 were ISS stageⅢ, and 12 had plasmacytoma; 32.5% of all patients were cytogenetic high-risk. All patients re-ceived a median of four cycles (range: 1-9) of the RVD regimen as induction treatment. The overall response rate was 97.9%, with 35.4% of patients achieving complete response (CR) or better. The rate of very good partial remission (VGPR) or better was increased from 64.1% (after two cycles) to 84.6% (after four cycles). The mean collection of CD34+cells was 4.2 (± 2.6)×106/kg. Negative minimal residual disease (MRD), as indicated by next-generation flow (NGF), was achieved in 20.6% of patients after induction. Two patients with positive MRD after induction became MRD negative after transplantation. Two patients developed grade 3 or 4 hematologic toxic-ity. No nonhematologic toxicity of grade 3 or 4 was observed. Conclusions: In patients with NDMM, RVD treatment resulted in signifi-cantly improved response rates and exhibited an acceptable risk-benefit profile, with no adverse impact on stem cell collection. RVD combined with transplantation significantly improved the negative rate of MRD, as indicated by NGF.

Objective:To investigate the clinical effect of proper management of inferior pancreaticoduodenal artery (IPDA) in laparoscopic pancreaticoduodenectomy (LPD).Methods:This is a retrospective case series study. The clinical and pathological data of 70 patients who received LPD due to pancreatic head tumors, periampullary tumors, or distal common bile duct tumors in the Pancreatic Center of the Second Clinical College of Guangzhou University of Chinese Medicine from January to December 2022 were retrospectively collected. There were 47 males(67.1%) and 23 females(32.9%),aged (59.9±12.8)years(range:13 to 87 years).The procedure of IPDA exposure was as follows:a middle approach was utilized to expose the right half of superior mesenteric artery(SMA) and its right branches between the SMA and superior mesenteric vein(SMV) in superior colonic region. In the subcolonic region,SMA trunk exposure via dissection along the jejunal artery from feet to head and identification the association between IPDA and jejunal artery were prior to IPDA root ligation and dissection. The safety and efficacy of intraoperative IPDA handling were assessed based on surgical videos. Follow-up was carried out in outpatient clinic or by telephone, and outpatient follow-up was conducted once every 1 to 3 months after surgery.Results:The percentage of total LPD was 98.6%(69/70),with all patients achieving R0 resection. Nine cases(12.9%) were involved in combined vascular resection and reconstruction,with 1 case (1.4%) requiring additional upper abdominal incision for vascular and gastrointestinal reconstruction,while the remaining eight cases (11.4%) were completed laparoscopically. The operative time was (432.7±115.4)minutes(range:282 to 727 minutes), and the blood loss was (140.0±125.7)ml(range:20 to 800 ml). Only two patients(2.9%) received fresh frozen plasma transfusion,with an average volume of 650 ml. Reliable ligation and safe handling of the IPDA were achieved in 91.4%(64/70) of cases, with 8.6%(6/70) suffering from IPDA injury-related bleeding. No one was converted to opened surgery. Pathologically,the mean tumor size was (3.3±1.6)cm (range:1 to 7 cm),and the mean number of harvested lymph nodes was 17.0±7.3(range:0 to 46). Lymph node metastasis was observed in 13 cases (18.6%). Five cases (13.2%) developed grade B pancreatic fistula,while no grade C pancreatic fistula occurred. Other complications included bile leakage in one case(1.4%),delayed gastric emptying in two cases(2.9%), lymphatic leakage in 2 cases(2.9%),intra-abdominal infection in 9 cases(12.9%),and fat liquefaction of surgical incision in 1 case(1.4%). Two cases(2.9%) experienced postoperative intra-abdominal bleeding,one due to mesangial bleeding of lesser curvature of the stomach and the other due to oozing from the hepatic arterial sheath. These bleeding events were not concerned with IPDA. The average length of postoperative hospital stay was (15.2±4.6)days(range:9 to 28 days).Conclusion:Proper intraoperative management of IPDA in LPD might reduce IPDA-related bleeding during and after surgery and improve the safety of LPD.

Recurrent spontaneous abortion (RSA) is a common gynecological disease during pregnancy, clinically characterized by repeated spontaneous abortions, yet its pathological mechanism remains incompletely understood. Traditional Chinese medicine attributes the pathogenesis of RSA to the deficiency of Chong Ren and the lack of fetal solidity. It has amassed experience in treating RSA, with Shoutaiwan being widely utilized for addressing miscarriage symptoms such as habitual abortion due to kidney deficiency, bleeding during pregnancy, and fetal movement. In recent years, there has been a gradual increase in experimental studies on the application of Shoutaiwan in treating RSA and on related experiments. These studies have demonstrated that Shoutaiwan preserves the fetus mainly by modulating hormone balance, alleviating immune inflammation, and enhancing blood coagulation equilibrium during pregnancy. Besides, through the modulation of key signaling pathways such as nuclear factor, erythroid 2 like 2 (Nrf2)/heme oxygenase-1 (HO-1) and Janus kinase 1 (JAK1)/signal transducer and activator of transcription (STAT), as well as mitogen-activated protein kinase (MAPK), Shoutaiwan has improved cellular antioxidant capacity, adjusted the phenotype of trophoblast and metaphase cells, and inhibited immune rejection, thus improving the pregnancy success rate. These findings not only elucidate the diverse biological foundations underlying Shoutaiwan's efficacy in treating RSA but also offer a scientific rationale for its clinical application and further mechanism research. Nonetheless, there remains a dearth of systematic reviews on RSA treatment with Shoutaiwan. Therefore, this review summarizes and synthesizes existing research findings to systematically analyze existing literature and studies, delving deeply into the principal pharmacological effects and associated signaling pathways of Shoutaiwan in regulating RSA. It aims to establish crucial reference points for its clinical application in RSA treatment and future experiments and research.
