Jiuwei Xifeng Granules have become a Chinese patent medicine in the market. Because the formula contains Os Draconis, a top-level protected fossil of ancient organisms, the formula was to be improved by replacing Os Draconis with Ostreae Concha. To evaluate whether the improved formula has the same effectiveness and safety as the original formula, a randomized, double-blind, parallel-controlled, equivalence clinical trial was conducted. This study enrolled 288 tic disorder(TD) of children and assigned them into two groups in 1∶1. The treatment group and control group took the modified formula and original formula, respectively. The treatment lasted for 6 weeks, and follow-up visits were conducted at weeks 2, 4, and 6. The primary efficacy endpoint was the difference in Yale global tic severity scale(YGTSS)-total tic severity(TTS) score from baseline after 6 weeks of treatment. The results showed that after 6 weeks of treatment, the declines in YGTSS-TSS score showed no statistically significant difference between the two groups. The difference in YGTSS-TSS score(treatment group-control group) and the 95%CI of the full analysis set(FAS) were-0.17[-1.42, 1.08] and those of per-protocol set(PPS) were 0.29[-0.97, 1.56], which were within the equivalence boundary [-3, 3]. The equivalence test was therefore concluded. The two groups showed no significant differences in the secondary efficacy endpoints of effective rate for TD, total score and factor scores of YGTSS, clinical global impressions-severity(CGI-S) score, traditional Chinese medicine(TCM) response rate, or symptom disappearance rate, and thus a complete evidence chain with the primary outcome was formed. A total of 6 adverse reactions were reported, including 4(2.82%) cases in the treatment group and 2(1.41%) cases in the control group, which showed no statistically significant difference between the two groups. No serious suspected unexpected adverse reactions were reported, and no laboratory test results indicated serious clinically significant abnormalities. The results support the replacement of Os Draconis by Ostreae Concha in the original formula, and the efficacy and safety of the modified formula are consistent with those of the original formula.

OBJECTIVE: To explore the clinical efficacy of orthopedic manipulation combined with daoyin exercises in the treatment of chronic lumbar disc herniation under the guidance of the theory of "equal emphasis on muscles and bones". METHODS: A total of 60 patients with single-segment, unilateral chronic lumbar disc herniation from January 2023 to January 2024 were randomly divided into the traditional physical therapy group and the manipulation treatment group, with 30 cases in each group. Among them, 3 cases were lost to follow-up in the traditional physical therapy group and 2 cases in the manipulation treatment group. There were 27 cases in the traditional physical therapy group, including 15 males and 12 females, aged 25 to 65 years old with an average of (51.96±14.42) years;the course of disease ranged from 3 to 15 months with an average of (9.89±3.32) months;11 cases were on the left side and 16 cases on the right side;15 cases were at the L4, 5 segment and 12 cases at the L5S1 segment. They were treated with lumbar traction, medium-frequency electrical stimulation and ultrasonic therapy. There were 28 cases in the manipulation treatment group, including 14 males and 14 females, aged 24 to 68 years old with an average of (49.82±14.85) years old;the course of disease ranged from 3 to 14 months with an average of (9.61±3.05) months;15 cases were on the left side and 13 cases on the right side;17 cases were at the L4, 5 segment and 11 cases at the L5S1 segment. They were treated with orthopedic manipulation combined with daoyin exercises. The visual analogue scale (VAS), Oswestry disability index (ODI) and bilateral erector spinae muscle tone were compared between the two groups before treatment, after 2 weeks and 4 weeks of treatment. RESULTS: The two groups of patients were followed up and evaluated before treatment, 2 weeks and 4 weeks after treatment. The VAS of the manipulation treatment group and the traditional physical therapy group decreased from (5.46±0.99) and (5.41±1.05) points before treatment to (1.75±0.79) and (2.29±0.82) points after 4 weeks of treatment, respectively. Both groups were significantly improved after treatment compared with before treatment, and the differences were statistically significant (P<0.05);and the manipulation treatment group was better than the traditional physical therapy group at 4 weeks of treatment, with a statistically significant difference (P<0.05). The ODI of the manipulation treatment group and the traditional physical therapy group before treatment was (20.25±2.72) and (18.96±2.52) points, respectively, which decreased to (15.46±1.88) and (16.56±2.01) points after 2 weeks of treatment, and to (11.54±1.23) and (12.85±1.72) points after 4 weeks of treatment. Both groups were significantly improved after treatment compared with before treatment, and the differences were statistically significant (P<0.05), and the ODI in the manipulation treatment group was better than that in the traditional physical therapy group after treatment (P<0.05). There was no significant statistical difference in the displacement of erector spinae muscle tone between the healthy side and the affected side in both the manipulation treatment group and the traditional physical therapy group before treatment (P>0.05). After 2 weeks of treatment, the displacement values of erector spinae muscle tone on the healthy side in the manipulation treatment group and the traditional physical therapy group were (6.68±0.81) mm and (6.45±0.65) mm, respectively, and those on the affected side were (5.87±0.82) mm and (5.61±0.84) mm, respectively. After 4 weeks of treatment, the displacement values of erector spinae muscle tone on the healthy side in the manipulation treatment group and the traditional physical therapy group were (7.51±0.75) mm and (7.04±0.63) mm, respectively, and those on the affected side were (6.87±0.78) mm and (6.33±0.82) mm, respectively. The displacement values of erector spinae muscle tone on both the healthy and affected sides in both groups were significantly higher than those before treatment, and the differences were statistically significant (P<0.05);the displacement of erector spinae muscle tone in the manipulation treatment group after 4 weeks of treatment was better than that in the traditional physical therapy group, with a statistically significant difference (P<0.05). CONCLUSION Orthopedic manipulation combined with daoyin exercises can effectively improve the symptoms and lumbar function of patients with chronic lumbar disc herniation, and has more advantages in improving the tone of the erector spinae muscle.

OBJECTIVES: To explore the factors related to prognosis and treatment failure in children with acute lymphoblastic leukemia (ALL). METHODS: A retrospective study was conducted to collect and analyze clinical data of ALL children admitted to the Department of Pediatric Hematology at Tongji Hospital, Huazhong University of Science and Technology, from January 2012 to December 2019, with follow-up until June 2024. RESULTS: A total of 341 children with ALL were included. Among the 69 children with treatment failure, 55 (80%) experienced relapse, while 14 (20%) had non-relapse-related deaths, and no secondary tumors were observed. Initial WBC count ≥50×10⁹/L, positive minimal residual disease, and severe adverse events were identified as independent risk factors for treatment failure (P<0.05). Among the 55 relapsed patients, early relapses were predominant (36%), and the primary site of relapse was the bone marrow (56%). Immunophenotyping (P=0.009), initial WBC count (P=0.011), and fusion genes (P=0.040) were associated with the timing of relapse. High-risk status, T-cell ALL, relapse, and severe adverse events were independent risk factors affecting long-term survival (P<0.05). CONCLUSIONS The prognosis of children with ALL is related to risk stratification, immunophenotyping, relapse status, and occurrence of severe adverse events. Among these factors, relapse is the primary cause of treatment failure. Actively preventing relapse may reduce the treatment failure rate and improve long-term survival.

A retrospective analysis was conducted on the clinical course of two children with PICALM-MLLT10-positive acute leukemia treated at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, between July 2021 and July 2023. The patients were diagnosed with acute T-lymphoblastic leukemia with central nervous system involvement and high-risk acute myeloid leukemia, respectively. Both achieved bone marrow complete remission after conventional chemotherapy combined with venetoclax. Following conversion to molecular negativity, they underwent sequential allogeneic hematopoietic stem cell transplantation. At the latest follow-up, both patients were alive and in good clinical condition. These observations suggest that proceeding to hematopoietic stem cell transplantation after venetoclax-based chemotherapy may improve the long-term survival of children with PICALM-MLLT10-positive leukemia.

OBJECTIVE: To analyze the effect of COVID-19 infection on the mobilization and collection of autologous peripheral blood stem cells in patients with multiple myeloma. METHODS: The general baseline data, treatment factors before mobilization collection, collection status, and treatment overview after collection of autologous peripheral blood stem cells at Beijing Chaoyang Hospital affiliated with Capital Medical University from January 1, 2020 to July 15, 2023 were analyzed. RESULTS: 269 patients underwent mobilization and collection of autologous peripheral blood stem cells. Among them, 32 cases with COVID-19 infection history (COVID-19 group) and 237 cases without COVID-19 infection history (non-COVID-19 group). In the COVID-19 group, 17 cases were treated with chemotherapy (etoposide)+G-CSF, and 15 cases were treated with plerixafor +G-CSF. In the non-COVID-19 group, 214 cases were treated with chemotherapy +G-CSF, 17 cases were treated with plerixafor +G-CSF, and 6 cases were treated with chemotherapy + plerixafor +G-CSF. The number of CD34⁺ cells, collection success rate, and excellence rate in the COVID-19 group and the non-COVID-19 group were ［5.52 (0.94-26.87) vs 4.80 (0.53-37.20)］×10⁶/kg (P =0.610), (93.8% vs 85.2%) (P =0.275), (62.5% vs 49.4%) (P =0.190), respectively. Among 113 patients mobilized with etoposide +G-CSF, the number of CD34⁺ cells, success rate, and excellence rate collected from COVID-19 infection (17 cases) and non-COVID-19 infection (96 cases) were ［7.54 (2.66-26.87) vs 7.78 (2.26-37.20)］×10⁶/kg (P =0.847), (100.0% vs 100.0%) (no P value), (82.4% vs 86.5%) (P =0.655), respectively. Among 32 patients mobilized by plerixafor +G-CSF, the number of CD34⁺ cells, success rate and excellence rate of COVID-19 infection (15 cases) and non-COVID-19 infection (17 cases) were ［3.82 (0.94-7.27) vs 4.11 (0.53-9.05)］×10⁶/kg (P =0.821), (86.7% vs 88.2%) (P =0.893), (40.0% vs 35.3%) (P =0.784), respectively. In 32 patients with COVID-19 infection, the number of CD34⁺ cells collected by etoposide +G-CSF (17 cases) and plerixafor +G-CSF (15 cases), as well as the success rate and excellence rate were ［7.54 (2.66-26.87) vs 3.82(0.94-7.27)］×10⁶/kg (P =0.004), (100.0% vs 86.7%) (P =0.120), (82.4% vs 40.0%) (P =0.014), respectively. By 2023.7.31, 232 patients (86.2%, 232/269) had received transplantation, including 24 patients in the COVID-19 group and 208 patients in the non-COVID-19 group. The median number of CD34⁺ cells infused in the two groups was ［3.67 (2.50-13.44) vs 3.11(1.12-19.89)］×10⁶/kg (P =0.058), the median days of neutrophil engraftment ［11(9-13) vs 11(9-17)］ (P =0.674), the median days of platelet engraftment ［11(0-23), 12(0-43)］ (P =0.279), respectively. CONCLUSION The history of COVID-19 infection did not affect the PBSC mobilization, collection and transplantation of patients with myeloma. In patients with COVID-19 infection, the results of chemotherapy mobilization with etoposide seems to be better than that of plerixafor mobilization, but further research is needed to clarify.

OBJECTIVE: To investigate the expression levels and combined detection efficiency of serum mean corpuscular volume (MCV), mean platelet volume (MPV), and tumor gene ( WT-1) in elderly patients with myelodysplastic syndrome (MDS). METHODS: One hundred elderly MDS patients admitted to our hospital from January 2020 to January 2021 were selected as observation group, and eighty healthy subjects during the same period were selected as control group. The levels of MCV, MPV and WT-1 were detected, and receiver operating characteristic (ROC) curve was drawn to analyze the value of combined detection of the three indicators in the prediction of MDS. The expression and correlation of MCV, MPV and WT-1 in elderly patients with MDS were analyzed and evaluated. RESULTS: The levels of MCV, MPV, and WT-1 in the observation group were higher than those in the control group (all P <0.001). Pearson correlation analysis showed that MCV was positively correlated with MPV and WT-1 (r =0.724, 0.733), while MPV was positively correlated with WT-1 (r =0.731). MCV, MPV, and WT-1 were independent influencing factors for elderly MDS (all P <0.05). The combined detection of the three indicators had the largest area under the curve (AUC) (0.873, 95%CI : 0.776-0.893) in the diagnosis of elderly MDS, with a sensitivity of 95.00%, a specificity of 90.00%, and Youden index of 0.850. The diagnostic value was significantly higher than that of a single indicator (both P <0.05). The levels of MCV, MPV, and WT-1 in severe patients were significantly higher than those in mild patients (all P <0.01). Logistic regression analysis showed that high expression of MCV, MPV, and WT-1 were influencing factors of severe elderly MDS. The ROC curve analysis showed that the combined diagnosis of MCV, MPV and WT-1 had the largest AUC for predicting severe MDS in elderly patients (0.897, 95%CI : 0.709-0.926), and the sensitivity and specificity were 93.18% and 91.07%, respectively (P <0.05). CONCLUSION MCV, MPC, and WT-1 are highly expressed in elderly patients with severe MDS. These three indicators can reflect the bone marrow hematopoietic function status of the subjects. However, compared with single indicator detection, the combined detection of the three indicators is more effective in diagnosis. It has certain advantages in elderly MDS and disease staging, and its promotion and application value is higher.

OBJECTIVE: To investigate the effects of astragaloside IV (AS-IV) on podocyte injury of diabetic nephropathy (DN) and reveal its potential mechanism. METHODS: In in vitro experiment, podocytes were divided into 4 groups, normal, high glucose (HG), inositol-requiring enzyme 1 (IRE-1) α activator (HG+thapsigargin 1 µmol/L), and IRE-1α inhibitor (HG+STF-083010, 20 µmol/L) groups. Additionally, podocytes were divided into 4 groups, including normal, HG, AS-IV (HG+AS-IV 20 µmol/L), and IRE-1α inhibitor (HG+STF-083010, 20 µmol/L) groups, respectively. After 24 h treatment, the morphology of podocytes and endoplasmic reticulum (ER) was observed by electron microscopy. The expressions of glucose-regulated protein 78 (GRP78) and IRE-1α were detected by cellular immunofluorescence. In in vivo experiment, DN rat model was established via a consecutive 3-day intraperitoneal streptozotocin (STZ) injections. A total of 40 rats were assigned into the normal, DN, AS-IV [AS-IV 40 mg/(kg·d)], and IRE-1α inhibitor [STF-083010, 10 mg/(kg·d)] groups (n=10), respectively. The general condition, 24-h urine volume, random blood glucose, urinary protein excretion rate (UAER), urea nitrogen (BUN), and serum creatinine (SCr) levels of rats were measured after 8 weeks of intervention. Pathological changes in the renal tissue were observed by hematoxylin and eosin (HE) staining. Quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the expressions of GRP78, IRE-1α, nuclear factor kappa Bp65 (NF-κBp65), interleukin (IL)-1β, NLR family pyrin domain containing 3 (NLRP3), caspase-1, gasdermin D-N (GSDMD-N), and nephrin at the mRNA and protein levels in vivo and in vitro, respectively. RESULTS: Cytoplasmic vacuolation and ER swelling were observed in the HG and IRE-1α activator groups. Podocyte morphology and ER expansion were improved in AS-IV and IRE-1α inhibitor groups compared with HG group. Cellular immunofluorescence showed that compared with the normal group, the fluorescence intensity of GRP78 and IRE-1α in the HG and IRE-1α activator groups were significantly increased whereas decreased in AS-IV and IRE-1α inhibitor groups (P<0.05). Compared with the normal group, the mRNA and protein expressions of GRP78, IRE-1α, NF-κ Bp65, IL-1β, NLRP3, caspase-1 and GSDMD-N in the HG group was increased (P<0.05). Compared with HG group, the expression of above indices was decreased in the AS-IV and IRE-1α inhibitor groups, and the expression in the IRE-1α activator group was increased (P<0.05). The expression of nephrin was decreased in the HG group, and increased in AS-IV and IRE-1α inhibitor groups (P<0.05). The in vivo experiment results revealed that compared to the normal group, the levels of blood glucose, triglyceride, total cholesterol, BUN, blood creatinine and urinary protein in the DN group were higher (P<0.05). Compared with DN group, the above indices in AS-IV and IRE-1α inhibitor groups were decreased (P<0.05). HE staining revealed glomerular hypertrophy, mesangial widening and mesangial cell proliferation in the renal tissue of the DN group. Compared with the DN group, the above pathological changes in renal tissue of AS-IV and IRE-1α inhibitor groups were alleviated. Quantitative RT-PCR and Western blot results of GRP78, IRE-1α, NF-κ Bp65, IL-1β, NLRP3, caspase-1 and GSDMD-N were consistent with immunofluorescence analysis. CONCLUSION AS-IV could reduce ERS and inflammation, improve podocyte pyroptosis, thus exerting a podocyte-protective effect in DN, through regulating IRE-1α/NF-κ B/NLRP3 signaling pathway.

OBJECTIVE: Exposure to polycyclic aromatic hydrocarbons (PAHs) or metal(loid)s individually has been associated with neural tube defects (NTDs). However, the impacts of PAH and metal(loid) co-exposure and potential interaction effects on NTD risk remain unclear. We conducted a case-control study in China among population with a high prevalence of NTDs to investigate the combined effects of PAH and metal(loid) exposures on the risk of NTD. METHODS: Cases included 80 women who gave birth to offspring with NTDs, whereas controls were 50 women who delivered infants with no congenital malformations. We analyzed the levels of placental PAHs using gas chromatography and mass spectrometry, PAH-DNA adducts with ³²P-post-labeling method, and metal(loid)s with an inductively coupled plasma mass spectrometer. Unconditional logistic regression was employed to estimate the associations between individual exposures and NTDs. Least absolute shrinkage and selection operator (LASSO) penalized regression models were used to select a subset of exposures, while additive interaction models were used to identify interaction effects. RESULTS: In the single-exposure models, we found that eight PAHs, PAH-DNA adducts, and 28 metal(loid)s were associated with NTDs. Pyrene, selenium, molybdenum, cadmium, uranium, and rubidium were selected through LASSO regression and were statistically associated with NTDs in the multiple-exposure models. Women with high levels of pyrene and molybdenum or pyrene and selenium exhibited significantly increased risk of having offspring with NTDs, indicating that these combinations may have synergistic effects on the risk of NTDs. CONCLUSION Our findings suggest that individual PAHs and metal(loid)s, as well as their interactions, may be associated with the risk of NTDs, which warrants further investigation.
