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 evaluate the consistency of mass spectrometry (MS) and chemiluminescence immunoassay (CLIA) in detecting serum insulin-like growth factor-1 (IGF-1) and IGF-1 standard deviation score (SDS). Methods: This cross-sectional parallel control study prospectively collected the serum samples of 115 children with short stature disorders who were admitted in the Department of Endocrinology, Beijing Children's Hospital, Capital Medical University from February 2020 to December 2021. The serum IGF-1 level was detected by CLIA and MS, and converted to SDS for consistency analysis. Pearson analysis was used to analyze the correlation between the 2 methods, and Deming regression equation was established. Bland-Altman diagram and weighted Kappa coefficient were used to evaluate the consistency of the 2 methods. Results: There were 46 boys (40.0%) and 69 girls (60.0%), aged (8±3) years. Among the 115 cases, 37 were Turner syndrome, 59 were small for gestational age (SGA) at term, 1 was growth hormone deficiency (GHD) and 18 were other diseases. Pearson correlation analysis showed a preferable correlation between IGF-1 measured by the 2 detection methods (r=0.94, P<0.01), and IGF-1 SDS was also significantly correlated (r=0.92, P<0.01). Bland-Altman analysis showed that the consistency of serum IGF-1 levels detected by the 2 methods was poor, and the mean difference between CLIA and MS was 33.38 μg/L. The result detected by CLIA was significantly higher than that by MS, with SDS of 43.51 μg/L (95%CI -51.89-118.7 μg/L). After converting the results to SDS and removing 3 outliers (including 1 GHD patient), the weighted Kappa showed acceptable consistency (κ=0.68). Conclusion: In clinical application, after converting to IGF-1 SDS, IGF-1 detected by MS and CLIA can be used for cross-reference, but too high or too low levels should be cautious about.

Objective:To investigate the possible mechanism of Xieheyin in alleviating obese polycystic ovary syndrome with insulin resistance（PCOS-IR）and reducing inflammatory response. Method:Ten of sixty SPF femlae C57BL/6J mice were randomly selected as the normal group，and the rest mice were given letrozole 0.002 g·kg^-1 combined with fecal suspension 2 g·kg^-1 for 28 consecutive days to establish model of PCOS-IR.The mice that were successfully modeled were randomized into the model group，metformin group（0.25 g·kg^-1），and low（10 g·kg^-1），medium（20 g·kg^-1），and high-dose（40 g·kg^-1）Xieheyin groups，and administered with the corresponding drugs by gavage，once a day，for four consecutive weeks. Except the normal control group， the mice in the other groups were continuously given fecal suspension combined with letrozole solution to maintain the model during the treatment. The mice were weighed once a week.Levels of fasting blood glucose （FBG） were detected by blood glucose test strips.And enzyme-linked immunosorbent assay （ELISA） method was used to detect serum testosterone（T），follicle stimulating hormone（FSH），luteinizing hormone（LH），fasting insulin（FINS）level，and LH/FSH and Homeostasis model assesment of insulin resistance （HOMA-IR） were calculated．The uterus and ovaries were weighed and fixed.Hematoxylin-eosin（HE）staining was used to observe ovarian tissue pathology morphology. Western blot was used to detect the expression levels of tight junction key molecular zonula occludens 1（ZO-1），occludin in colon tissues，and the expression levels of Toll-like receptor 4/nuclear factor kappa B/Nod-like receptor protein 3（TLR4/NF-κB/NLRP3）signaling pathway and inflammation associated proteins cysteinyl aspartate specific proteinase-1（Caspase-1） and interleukin-1β（IL-1β） in colon tissues. Result:Compared with normal control group，the body weight of mice in the model control group increased significantly（P<0.01）. Serum FINS，FBG，HOMA-IR，T，LH/FSH were significantly increased（P<0.05，P<0.01）. The uterine organ ratio were decreased significantly（P<0.01），while the ovarian organ ratio were significantly increased（P<0.01）. The number of atresia follicles and cystic dilatation follicles increased significantly，and the number of corpus luteum significantly decreased，the thickness of follicular granulosa cells also decreased，while the white membrane thickness of the ovary increased. Tight junction related ZO-1，occludin proteins in colon tissues were all decreased（P<0.01）.The relative expression levels of inflammation-related protein IL-1β，Caspase-1 and TLR4/NF-κB/NLRP3 target protein signaling pathway were significantly increased（P<0.05）.Compared with model control group， the body weight of mice in the low，middle and high dose Xieheyin group decreased significantly（P<0.01）. The serum T，LH/FSH，FINS，FBG，HOMA-IR were significantly decreased（P<0.05，P<0.01）. The uterine organ ratio were increased（P<0.05），while the ovarian organ ratio were decreased（P<0.05）. The number of cystic follicles decreased and corpus luteum increased，the thickness of follicular granulosa cells increased and be arranged normally，while the white membrane thickness of the ovary increased slightly. The expressions of ZO-1，occludin proteins were increased（P<0.01）. The expression levels of IL-1β，Caspase-1 and TLR4/NF-κB/NLRP3 target protein in the high dose group were significantly decreased（P<0.01）. Conclusion:Xieheyin could activate intestinal TLR4/NF-κB/NLRP3 signaling pathway，inhibit pro-inflammatory factor secretion，improve obesity and IR，which was correlated with rebuilding intestinal mucosal barrier and inhibiting intestinal inflammation．

BACKGROUND: Compared to adult studies, studies which involve the treatment of pediatric congenital hypogonadotropic hypogonadism (CHH) are limited and no universal treatment regimen is available. The aim of this study was to evaluate the feasibility of human chorionic gonadotropin (hCG)/human menopausal gonadotropin (hMG) therapy for treating male adolescents with CHH. METHODS: Male adolescent CHH patients were treated with hCG/hMG (n = 20) or a gonadotropin-releasing hormone (GnRH) pump (n = 21). The treatment was divided into a study phase (0-3 months) and a follow-up phase (3-12 months). The testicular volume (TV), penile length (PL), penis diameter (PD), and sex hormone levels were compared between the two groups. The TV and other indicators between the groups were analyzed using a t-test (equal variance) or a rank sum test (unequal variance). RESULTS: Before treatment, there was no statistical difference between the two groups in terms of the biochemistry, hormones, and other demographic indicators. After 3 months of treatment, the TV of the hCG/hMG and GnRH groups increased to 5.1 ± 2.3 mL and 4.1 ± 1.8 mL, respectively; however, the difference was not statistically significant (P > 0.05, t = 1.394). The PL reached 6.9 ± 1.8 cm and 5.1 ± 1.6 cm (P < 0.05, t = 3.083), the PD reached 2.4 ± 0.5 cm and 2.0 ± 0.6 cm (P < 0.05, t = 2.224), respectively, in the two groups. At the end of 6 months of treatment, biomarkers were in normal range in the two groups. Compared with the GnRH group, the testosterone (T) level and growth of PL and PD were significantly greater in the hCG/hMG group (all P < 0.05). While the TV of both groups increased, the difference was not statistically significant (P > 0.05, t = 0.314). After 9 to 12 months of treatment, the T level was higher in the hCG/hMG group. Other parameters did not exhibit a statistical difference. CONCLUSIONS: The hCG/hMG regimen is feasible and effective for treating male adolescents with CHH. The initial 3 months of treatment may be a window to optimally observe the strongest effects of therapy. Furthermore, results from the extended time-period showed positive outcomes at the 1-year mark; however, the long-term effectiveness, strengths, and weaknesses of the hCG/hMG regimen require further research.

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.

There are more and more literature reports about the application of Chinese medicine quality constant in the grading evaluation of Chinese medicine decoction pieces. Chinese medicine quality constant has particularly prominent advantages in comprehensive quantification,so it has become a new method and mode for grading Chinese medicine decoction pieces,highly recognized by the academic circle. In order to determine the effect of Chinese medicine quality constant,a method of grades evaluation for Moutan cortex was established in this paper. 15 batches of samples were collected from Chinese herbal slices enterprises to determine the external morphological indexes and inner quality indexes,calculate the Chinese medicine quality constant of Moutan cortex,and divide them into different grades. The results revealed that the range of the relative quality constant of these samples was from 0. 016 to 0. 060,with percentage quality constant from 27. 4 to 100. 0. If these samples were divided into three grades: the quality constant of the first grade should be ≥0. 048 or the percentage quality constant ≥80. 0; the quality constant of the second grade should be <0. 048 but ≥0. 030 or percentage quality constant <80. 0 and ≥50. 0; the quality constant of the third grade should be <0. 030 or the percentage quality constant <50. 0. This research indicated that Chinese quality constant can objectively divide grades of Moutan cortex decoction pieces,providing reference for formulating grades standards. It was also verified from the results that traditional quality evaluation of Moutan cortex was consistent with quality constant,and the connotation of percentage quality constant was elaborated as well. At the same time,it is suggested to establish a third-party Chinese medicine slices rating agency as soon as possible,which is to unify the terminology and provide rating services for the market.

Objective: To compare the time of the recovery of neutrophils or leukocytes by pegylated recombinant human granulocyte stimulating factor (PEG-rhG-CSF) or common recombinant human granulocyte stimulating factor (rhG-CSF) in the myelosuppressive phase after induction chemotherapy in newly diagnosed acute myeloid leukemia (AML) patients. At the same time, the incidences of infection and hospitalization were compared. Methods: A prospective randomized controlled trial was conducted in patients with newly diagnosed AML who met the enrollment criteria from August 2014 to December 2017. The patients were randomly divided into two groups according to a 1:1 ratio: PEG-rhG-CSF group and rhG-CSF group. The time of neutrophil or leukocyte recovery, infection rate and hospitalization interval were compared between the two groups. Results: 60 patients with newly diagnosed AML were enrolled: 30 patients in the PEG-rhG-CSF group and 30 patients in the rhG-CSF group. There were no significant differences in age, chemotherapy regimen, pre-chemotherapy ANC, WBC, and induction efficacy between the two groups (P>0.05) . The median time (range) of ANC or WBC recovery in patients with PEG-rhG-CSF and rhG-CSF were 19 (14-35) d and 19 (15-26) d, respectively, with no statistical difference (P=0.566) . The incidences of infection in the PEG-rhG-CSF group and the rhG-CSF group were 90.0%and 93.3%, respectively, and there was no statistical difference (P=1.000) . The median days of hospitalization (range) was 20.5 (17-49) days and 21 (19-43) days, respectively, with no statistical difference (P=0.530) . Conclusions: In AML patients after induction therapy, there was no significant difference between the application of PEG-rhG-CSF and daily rhG-CSF in ANC or WBC recovery time, infection incidence and hospitalization time.

OBJECTIVETo evaluate the efficacy of primary prophylaxis of voriconazole against invasive infection of pulmonary aspergillosis (IPA) during remission-induction chemotherapy (RIC) of patients with acute myeloid leukemia (AML).

METHODSClinical data of 102 de novo AML patients who received primary anti-IPA prophylaxis during the first induction chemotherapy were analyzed retrospectively. All the cases were divided into voriconazole-treated group and posaconazole-treated group according to the prophylactic agent. The incidences of IPA and systemic antifungal treatment during induction chemotherapy were analyzed for both groups.

RESULTSAmong 102 enrolled cases, 42 cases received voriconazole and other 60 received posaconazole as primary prophylaxis. IPA occurred in 3 cases of voriconazole group (1 probable, 2 possible); IPA occurred in 4 cases of posaconazose group, and all were possible cases. The incidence of IPA during remission-induction chemotherapy in variconazole group equaled to posaconazose group (7.1% vs. 6.7%) (P=0.925). Beside IPA cases, 2 cases in voriconazole group and 4 cases in posaconazole group received intravenous anti aspergillosis drugs preemptive treatment, and no significant difference of prophylactic success rate was observed between two groups (88.1% vs. 86.7%) (P=0.831). Visual disturbance was the most common adverse event occurred in voriconazole group, but no significant differences of incidences of other adverse effects were observed when compared with posaconazole group.

CONCLUSIONAccording to similar prophylactic effect with posaconazole, voriconazole appears to be a good alternative for primary prophylaxis of IPA during remission-induction chemotherapy in AML patients.

ObjectiveTo investigate the role of the serum inhibin B (INHB) level in evaluating the testicular function of the prepubertal patient with varicocele (VC) after high ligation of the spermatic vein (HLSV).

METHODSThis study included 31 prepubertal male patients with left VC, averaging 12.55 years of age and 9 complicated by right VC. We collected peripheral blood samples before and at 4, 12 and 26 weeks after HLSV as well as spermatic venous blood samples intraoperatively for determination of the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), anti-sperm antibody (AsAb) and serum INHB by ELISA.

RESULTSCompared with the baseline, statistically significant differences were observed in the INHB level in the peripheral blood at 12 and 26 weeks after operation (［255.18 ± 69.97］ vs ［141.78 ± 59.82］ pg/ml, P < 0.05) and that in the spermatic venous blood intraoperatively (［255.18 ± 69.97］ vs ［412.44 ± 259.42］ pg/ml, P < 0.01). Spearman's analysis showed a negative correlation between the level of INHB and that of FSH (r = －0.224, P < 0.01).

CONCLUSIONSThe level of serum INHB in the peripheral blood of the prepubertal VC patient is decreased within 6 months after HLSV and negatively correlated with that of FSH. The levels of INHB and FSH may well reflect the testicular function of the prepubertal VC patient.
