Using data mining technology, the rules of acupoint selection of acupuncture and moxibustion were explored in treatment of stroke-related pneumonia. The clinical articles of acupuncture and moxibustion in treatment of stroke-related pneumonia were retrieved from CNKI, SinoMed, Wanfang and VIP databases from their inception through to January l 2021, and then, the acupuncture-moxibustion prescription database was set up for stroke-related pneumonia. SPSS Modeler 18.0 Apriori algorithm was adopted to analyze the association rules of acupoints and draw complex network diagrams. SPSS26.0 was used in clustering analysis of acupoints. Finally, a total of 44 articles were included, with 51 acupoint prescriptions and 82 acupoints extracted. The total frequency of acupoints was 340 times. The high-frequency acupoints in treatment with acupuncture and moxibustion for stroke-related pneumonia were Feishu (BL 13), Fenglong (ST 40), Hegu (LI 4), etc. These acupoints were mainly distributed on the limbs and back and mostly from yang meridians. Of these extracted acupoints, the five-shu points, convergent points and back-shu points were selected specially. Regarding acupoint combination, the association of Quchi (LI 11) had the highest support with Hegu (LI 4) and Zusanli (ST 36). The core prescription of acupuncture-moxibustion treatment for stroke-related pneumonia could be composed of Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36), Fenglong (ST 40) and Taichong (LR 3).

Objective: To compare the efficacy of two induction regimens, namely, idarubicin combined with cytarabine (IA) versus the combination of homoharringtonine, daunorubicin, and cytarabine (HAD) , in adult patients with newly diagnosed de novo acute myeloid leukemia (AML) . Methods: From May 2014 to November 2019, 199 patients diagnosed with AML receiving either the IA or HAD regimens were assessed for overall survival (OS) , relapse-free survival (RFS) , as well as the CR rate and the MRD negative rate after induction therapy. The differences in prognosis between the two induction therapy groups was assessed according to factors, including age, white blood cell (WBC) count, NPM1 mutation, FLT3-ITD mutation, 2017 ELN risk stratification, CR(1) transplantation, and the use of high-dose cytarabine during consolidation therapy, etc. Results: Among the 199 patients, there were 104 males and 95 females, with a median age of 37 (15-61) years. Ninety patients received the IA regimen, and 109 received the HAD regimen. Comparing the efficacy of the IA and HAD regimens, the CR rates after the first induction therapy were 71.1% and 63.3%, respectively (P=0.245) , and the MRD negative rates after the first induction therapy were 53.3% and 48.6%, respectively (P=0.509) . One patient in the IA group and two in the HAD group died within 60 days after induction. The two-year OS was 61.5% and 70.6%, respectively (P=0.835) , and the two-year RFS was 51.6% and 57.8%, respectively (P=0.291) . There were no statistically significant differences between the two groups. Multivariate analysis showed that the ELN risk stratification was an independent risk factor in both induction groups; CR(1) HSCT was an independent prognostic factor for OS and RFS in the IA patients and for RFS in the HAD patients but not for OS in the HAD patients. Age, WBC level, NPM1 mutation, and FLT3-ITD mutation had no independent prognostic significance. Conclusion: The IA and HAD regimens were both effective induction regimens for AML patients.

Objective: To evaluate the efficacy and toxicity profiles of idarubicin, cytarabine, and cyclophosphamide (IAC) in relapse/refractory acute myeloid leukemia (AML) . Methods: This study was a prospective, randomized controlled clinical trial with the registration number NCT02937662. The patients were randomly divided into two groups. The experimental group was treated with an IAC regimen, and the regimen of the control group was selected by doctors according to medication experience. After salvage chemotherapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) was conducted as far as possible according to the situation of the patients. We aimed to observe the efficacy, safety, and toxicity of the IAC regimen in relapse/refractory AML and to explore which is the better regimen. Results: Forty-two patients were enrolled in the clinical trial, with a median age of 36 years (IAC group, 22 cases and control groups, 20 cases) . ①The objective response rate was 71.4% in the IAC group and 40.0% in the control group (P=0.062) ; the complete remission (CR) rate was 66.7% in the IAC group and 40.0% in the control group (P=0.121) . The median follow-up time of surviving patients was 10.5 (range:1.7-32.8) months; the median overall survival (OS) was 14.1 (range: 0.6-49.1) months in the IAC group and 9.9 (range: 2.0-53.8) months in the control group (P=0.305) . The 1-year OS was 54.5% (95%CI 33.7%-75.3%) in the IAC group and 48.2% (95%CI 25.9%-70.5%) in the control group (P=0.305) , with no significant difference between these two regimens. ②The main hematologic adverse events (AEs) were anemia, thrombocytopenia, and neutropenia. The incidence of grade 3-4 hematologic AEs in the two groups was 100% (22/22) in the IAC group and 95% (19/20) in the control group. The median time of neutropenia after chemotherapy in the IAC group and control group was 20 (IQR: 8-30) and 14 (IQR: 5-50) days, respectively (P=0.023) . ③The CR rate of the early relapse (relapse within 12 months) group was 46.7% and that of the late relapse (relapse after 12 months) group was 72.7% (P=0.17) . The median OS time of early recurrence was 9.9 (range:1.7-53.8) months, and that of late recurrence patients was 19.3 (range: 0.6-40.8) months (P=0.420) , with no significant differences between the two groups. The 1-year OS rates were 45.3% (95%CI 27.2%-63.3%) and 66.7% (95%CI 40.0%-93.4%) , respectively (P=0.420) . Survival analysis showed that the 1-year OS rates of the hematopoietic stem cell transplantation group and non-hematopoietic stem cell transplantation group were 87.5% (95%CI 71.2%-100%) and 6.3% (95%CI 5.7%-18.3%) , respectively. The OS rate of the hematopoietic stem cell transplantation group was significantly higher than that of the non-hematopoietic stem cell transplantation group (P<0.001) . Conclusion: The IAC regimen is a well-tolerated and effective regimen in relapsed/refractory AML; this regimen had similar efficacy and safety with the regimen selected according to the doctor's experience for treating relapsed/refractory AML. For relapsed/refractory patients with AML, allogeneic hematopoietic stem cell transplantation should be attempted as soon as possible to achieve long-term survival.

OBJECTIVE:
To investigate the efficacy and safety of arsenic trioxide combined with ATRA and chemo- therapy for treatment of relapsed acute promyelocytic leukemia (APL) patients.
METHODS:
The clinic data of 25 patients with relapse APL treated in our hospital from 1996 to 2013 were collected and analyzed. Among the 25 patients, 15 patients suffered first-time hematological relapse (HR), and the other 10 patients showed first-time molecular relapse (MR). The patients with first-time replase were treated with ATO+ATRA+Anthracycline re-induction chemotherapy. The clinical features, complete remission (CR) rate, overall survival (OS), disease-free survival (DFS) and adverse events after re-induction therapy were analyzed.
RESULTS:
Fourteen of 15 hematological relapsed patients achieved the second-time hematological complete remission (CR2) after re-induction therapy except one patient died of bleeding complication during the re-induction. 8 of 14 patient showed molecular complete remission (CRm) after two cycles of therapy with this regimen. Totally, eleven out of the 14 HR patients were alive without disease till the last follow-up, and 3 of the 14 HR patients died because of bleeding complications. All of the 10 molecular relapsed patients received the second CRm after treated by the regimen. Among these 10 patients, 6 patients suffered only once relapse and continued with the molecular CR2 status, and for the other 4 patients with more than two-relapses, only 1 survived untill 89.3 months after achieved second-time CRm, and other 3 patients died because of bleeding complications.
CONCLUSION
For relapsed APL patients, the treatment with ATO+ATRA+chemotherapy regimen after relapse still shows encouraging efficacy, no matter whether or not the application of ATO in the previous regimens. In addition, patients with more than two molecular relapses show a poor prognosis.

Objective To understand the major genotype-resistant mutation sites and change trends of HIV/AIDS patients with failure of antiviral therapy (ART) in Lincang City, Yunnan Province. Methods The In-House method was used to amplify the Pol gene region in the plasma samples of HIV/AIDS patients with failure of ART in Lincang City from 2011 to 2018. The target sequence was spliced and submitted to the HIV resistance database to identify and analyze the HIV-1 subtypes and resistant mutation sites. Results The 950 strains of HIV/AIDS patients with antiviral failure were mainly CRF08_BC, accounting for 75.5% (717/950), and the total gene mutation rate was 67.1% (637/950), which was dominated by non-nucleoside reverse transcriptase inhibitors (NNRTIs), accounting for 62.4% (593/950); followed by nucleoside reverse transcriptase inhibitors (NRTIs), accounting for 34.7% (330/950); protease inhibitors (PIs) was 7.5% (71/950). A total of 15 NRTIs of resistance-related mutation sites were detected, mainly M184V (29.3%) which was detected mostly in AZT/D4T+3TC+NVP programs; including 17 kinds of NNRTIs, mainly was K103N/S (25.1%),the most detected in AZT/TDF+3TC+EFV programs. There were 22 kinds of PIs,mainly secondary sites were L10F/V/I (2.2%) and L33F (2.1%). The top three NRTIs mutation sites in the area were changed from T69D/N/G,M184I/V and D67N/G/S to M184I/V, K70R/Q/E/T and T215Y/F/V/I/N/A/D. NNRTIs mutation sites were changed from V179D/T/E/F, E138A/K/G/R and Y181C/F/G/V to K103N/S, E138A/K/G/R and V179D/T/E/F. The mutation sites of the first three PIs did not change much. Conclusions The second-line regimen based on PIs is a better choice in free antiviral treatments. Mastering the drug resistance of different gene mutations is beneficial to the compatibility of first-line drugs, thus delaying the use of second-line drugs.
