Objective To explore the clinical features of infection in multiple myeloma (MM)undergoing autologous hematopoietic stem cell transplantation (ASCT). Methods Thirty-seven patients with MM undergoing ASCT were retrospectively analyzed for type and time of infection, pathogen, and outcome. Results Fifty-nine cases of infectious complications occurred in 33 patients (89. 2% ) after ASCT, with 34 cases (57.6%) of bacterial infections in 30 patients, 15 cases (25.4%) of fungal infections in 12 patients, 4 cases (6. 8% ) of cytomegalovirus (CMV) infection, 3 cases (5. 1% ) of herpes zoster virus infection and 3 cases (5. 1% ) of HBV reactivation. The proportion of bacterial infection, fungal infection and virus infection were 62. 8%, 28.6% and 8. 6% respectively in the early stage after ASCT, and 50. 0%, 20. 8% and 29. 3% respectively in the median stage. Response to first-line antibiotic therapy was seen in 38 cases (64. 4% ). Infection-related mortality was 8. 1% (3 cases). Conclusions The incidence of infection in MM patients undergoing ASCT is high and they are susceptible to all pathogens. It is important to choose the right antifungal agents as quickly as possible to reduce infection-related mortality.

Objective:
To study the efficacy, safety and long-term outcomes of integrated strategy of bortezomib-based induction regimens followed by autologous hematopoietic stem cell (ASCT) and maintenance therapy in Chinese multiple myeloma (MM) patients.
Methods:
200 MM patients receiving integrated strategy of bortezomib--based induction regimens followed by ASCT and maintenance therapy were retrospectively and prospectively analyzed from December 1. 2006 to April 30. 2018.
Results:
The complete remission rates (CR) and better than very good partial remission rates (VGPR) after induction therapy, transplantation and maintenance therapy were respectively 31% and 75.5%, 51.8% and 87.7%,73.6% and 93.4%. There was no difference between 4 cycles and more than 5 cycles induction chemotherapy. The negative rate of MRD detection by flow cytometry was 17.6% and 38.2% respectively after induction and 3 months after transplantation. The negative rate of MRD gradually increased during the maintenance therapy. The success rate of high dose CTX combined with G-CSF mobilization was 95.5% and transplantation related mortality (TRM) was zero. The median time to progress (TTP) was 75.3 months and the median overall survival (OS) was 99.5 months. TTP of patients obtaining CR and negative MRD after induction were longer that those of no CR and positive MRD. TTP and OS of patients receiving triple-drug induction and ASCT in early stage were longer than those of double-drug induction and ASCT in late stage. LDH≥240 U/L, high risk cytogenetics, ISS II+III stage and HBsAg positive were prognostic factors at diagnosis. However, only MRD and high risk cytogenetics were independent prognostic factors after transplantation and maintenance therapy. The clinical characteristics of patients of TTP ≥6 years were listed below: light-chain type M protein, ISS I stage, normal level of hemoglobin and platelet, normal LDH, HBsAg negative, chromosome 17p-negative, good response and sustained good response.
Conclusions
Integrated strategy of bortezomib-based induction regimens followed by ASCT and maintenance therapy can significantly improve the short-term and long-term efficacy. The prognostic factors of TTP in different disease stages were different. Response to treatment, especially MRD, played a more important role in prognostic factors.

ObjectiveTo compare the clinical effect of heat-sensitive moxibustion before menstruation and since the first day of menstruation on primary dysmenorrhoea (PD), thereby optimizing the clinical treatment plan. MethodsSixty patients with PD were randomly divided into pretreatment group (treated before menstruation) and conventional treatment group (treated since the first day of menstruation) of 30 cases each. For all patients, the area surrounded by bilateral Zigong (EX-CA1) and bilateral Guilai (ST 29) in the supine position, and that formed by bilateral Shenshu (BL 23) and Ciliao (BL 32) in the prone position were selected for circling moxibustion (2 min), sparrow-pecking moxibustion (1 min), and then moxibustion along the channels to stimulate the moxibustion sensation and obtain two heat-sensitive points with the best sensation for treatment. In the pretreatment group, moxibustion was applied 3-7 days before the onset of menstruation, and in the conventional treatment group, moxibustion was applied on the day of menstruation. Both groups were treated once daily for 7 days per menstrual cycle for 3 consecutive cycles. The clinical outcomes of the two groups were measured before and after treatment in terms of the COX menstrual pain symptom scale (CMSS) scores, visual analogue scale for pain (VAS) scores, and uterine artery hemodynamic indicators including blood pulsation index (PI) and resistance index (RI), and the clinical effect was compared. ResultsAfter treatment, the CMSS scores, VAS scores, PI and RI in the two groups decreased, and lower scores were found in the pretreatment group (P<0.05 or P<0.01). The total effective rate after treatment was 93.3% (28/30) in the pretreatment group, which was better than 73.3% (22/30) in the conventional treatment group (P<0.05). ConclusionThe clinical effect of heat-sensitive moxibustion before the menstruation for PD was better than that implemented since the first day of menstruation, by significantly improving the patients' dysmenorrhoea symptoms and uterine artery blood flow index.

Metabolic regulation has been proven to play a critical role in T cell antitumor immunity. However, cholesterol metabolism as a key component of this regulation remains largely unexplored. Herein, we found that the low-density lipoprotein receptor (LDLR), which has been previously identified as a transporter for cholesterol, plays a pivotal role in regulating CD8
