Objective:To investigate the effects of Tiaogan Lifei Decoction on the level of symptom control in patients with bronchial asthma (asthma) treated with moderate and high dosage inhaled glucocorticoids (ICS).Methods:Randomized double-blind placebo controlled prospective study was used. Totally 90 patients with asthma (liver lung disharmony, wind phlegm blocking collateral syndrome) using moderate and high dosage ICS who met the inclusion criteria from January 2020 to December 2021 in Chaoyang District Hospital of Traditional Chinese Medicine in Beijing were divided into two groups according to random number table method, with 45 cases in each group. On the basis of using the original dosage of ICS, the treatment group used Tiaogan Lifei Decoction, while the control group used Tiaogan Lifei Decoction simulant. The course of treatment was 12 weeks. TCM symptom score of both group before and after the treatment was detected; asthma control test (ACT) was used to assess the effects of asthma on the patients; St George's Hospital Respiratory Questionnaire (SGRQ) was used to assess patients' quality of life; the peak expiratory flow rate (PEF) was measured with a peak expiratory flow meter. 2 ml of venous blood was collected for eosinophil (EOS) detection, and the serum allergen specific IgE level was determined by ELISA. The adverse reactions were observed during the treatment and the clinical efficacy was evaluated.Results:During the test, 3 cases and 2 cases in the treatment group and control group lost prevention respectively. 3 cases in the treatment group and 6 cases in the control group withdrew from the trial because of the aggravation of symptoms and the need to increase the dosage of ICS. The total effective rate in the treatment group was 78.6% (33/42), and that in the control group was 55.8% (24/43), with statistical significance ( χ2=4.98, P=0.026). After treatment, the scores of daily activities, early awakening, control and total scores in the treatment group were higher than those in the control group ( t values were 1.76, 1.99, 2.00, 2.69, respectively, P<0.01 or P<0.05); after treatment, the scores of cough, chest tightness, active wheezing, upset, pharyngeal itch and total score in the treatment group were lower than those in the control group ( t values were -5.89, -6.01, -5.66, -4.27, -6.67, -9.05, respectively, P<0.01); SGRQ score in the treatment group was lower than that of the control group ( t=-7.19, P<0.01). No serious adverse reactions occurred during treatment in the two groups. Conclusion:Tiaogan Lifei Decoction is helpful to improve the symptom control level of asthma patients who are using ICS, and effectively improve the quality of life of patients with asthma of liver lung disharmony and wind phlegm obstructing collaterals syndrome.

Objective:To explore the efficacy and safety of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) and human granulocyte colony-stimulating factor (G-CSF) for the prevention of post-chemotherapy infections in pediatric hematologic neoplasms.Methods:A total of 134 children hospitalized for chemotherapy in 6 tertiary hospitals from July 2016 to June 2018 were collected, including 60 cases in Children's Hospital of Fudan University, 38 cases in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, 29 cases in Children's Hospital Affiliated to Soochow University, 4 cases in the Affiliated Hospital of Qingdao University, 2 cases in Northwestern Women and Children's Hospital, and 1 case in Shandong Provincial Qianfoshan Hospital. The children were divided into GM-CSF group (38 cases), G-CSF group (45 cases) and GM-CSF+G-CSF group (51 cases) by using random number table method. The incidence of infections, the recovery time of absolute neutrophil counting (ANC), the decrease of blood platelet count (Plt) and the incidence of adverse reactions were compared among the three groups.Results:In all children, a total of 64 cases (47.8%) had infections during the myelosuppression phase after chemotherapy, of which 18 cases (47.4%) in GM-CSF group, 20 cases (44.4%) in G-CSF group, and 26 cases (51.0%) in GM-CSF+G-CSF group. The incidence of respiratory infection in G-CSF group was higher than that in GM-CSF group and GM-CSF+ G-CSF group [22.2% (10/45) vs. 2.6% (1/38), 4.0% (2/51), χ2 = 12.00, P = 0.002]. The median time to recovery of ANC > 1.5×10 9/L was 10.5 d (8 d, 15 d) in all children, 12 d (10 d, 16 d) in GM-CSF group, 9 d (8 d, 12 d) in G-CSF group, and 10 d (8 d, 16 d) in GM-CSF+G-CSF group. In all children, a total of 101 cases (75.4%) had Plt<50×10 9/L during the myelosuppression phase, and 79 cases (59.0%) had Plt <20×10 9/L. The differences in the incidence of Plt <50×10 9/L and <20×10 9/L among the three groups were not statistically significant (both P > 0.05). In all children, the adverse reactions occurred in 24 cases (17.9%), including 20 cases (14.9%) of fever, 2 cases (1.5%) of sore throat, 1 case (0.7%) of nausea, and 1 case (0.7%) of diarrhea; no adverse reactions of grade 2 or above occurred. The difference in the incidence of adverse reactions among the three groups was not statistically significant ( P>0.05). Conclusions:The efficacy of GM-CSF and G-CSF for the prevention of infections in pediatric hematologic neoplasms during the myelosuppression phase after chemotherapy is roughly equivalent, and combination of both has a good tolerance. The incidence of respiratory infection using GM-CSF alone or GM-CSF+G-CSF is low, which might benefit from the effect of GM-CSF on lung infections.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.

Background: Lumbar disc herniation (LDH) is a common cause of radicular pain, but the mechanism is not clear. In this study, we investigated the engagement of toll-like receptor 4 (TLR4) and the nuclear factor-kappa B (NF-κB) in radicular pain and its possible mechanisms. Methods: An LDH model was induced by autologous nucleus pulposus (NP) implantation, which was obtained from coccygeal vertebra, then relocated in the lumbar 4/5 spinal nerve roots of rats. Mechanical and thermal pain behaviors were assessed by using von Frey filaments and hotplate test respectively. The protein level of TLR4 and phosphorylated-p65 (p-p65) was evaluated by western blotting analysis and immunofluorescence staining. Spinal microglia activation was evaluated by immunofluorescence staining of specific relevant markers. The expression of proand anti-inflammatory cytokines in the spinal dorsal horn was measured by enzyme linked immunosorbent assay. Results: Spinal expression of TLR4 and p-NF-κB (p-p65) was significantly increased after NP implantation, lasting up to 14 days. TLR4 was mainly expressed in spinal microglia, but not astrocytes or neurons. TLR4 antagonist TAK242 decreased spinal expression of p-p65. TAK242 or NF-κB inhibitor pyrrolidinedithiocarbamic acid alleviated mechanical and thermal pain behaviors, inhibited spinal microglia activation, moderated spinal inflammatory response manifested by decreasing interleukin (IL)-1β, IL-6, tumor necrosis factor-α expression and increasing IL-10 expression in the spinal dorsal horn. Conclusions The study revealed that TLR4/NF-κB pathway participated in radicular pain by encouraging spinal microglia activation and inflammatory response.

Radiotherapy is the most common treatment for nasopharyngeal carcinoma, and the radiotherapy technique is essential for the prognosis of nasopharyngeal carcinoma. Due to the complexity of the structure of the intensity-modulated device and the accuracy of the clinical requirements of radiotherapy, it is inevitable that higher requirements will be imposed on the process of intensity-modulated radiotherapy. Currently, gaps exist in the radiotherapy equipment and personnel qualification among radiotherapy units, and thus the homogenization in the radiotherapy remains to be strengthened in China. With the application of radiotherapy information management system, digital medicine and artificial intelligence technologies in the field of radiotherapy, the original process fails to meet the application needs of the new precise radiotherapy technology. Therefore, this process is designed based on the existing radiotherapy procedures for nasopharyngeal carcinoma in combination with the latest developments in the field of radiotherapy, aiming to establish a novel standard process recommendation, ensuring the standardization and homogenization of radiotherapy and achieve the individualized intensity-modulated radiotherapy for nasopharyngeal carcinoma patients.

Objective: To explore the prognosis and risk factors of pyelectasis in high-risk infants. Methods: This was a retrospective study. Totally 960 high-risk infants, who accepted type B ultrasonic examination for fetus at 28th week of gestation and for newborns in 48 hours after birth, were included in the study in departments of obstetrics and eonatology, Shunyi Maternal and Children's Hospital of Beijing Children's Hospital during May 2012 to April 2013. The degree of pyelectasis was classified using Grignon grade and the paients were followed up for 3 years. The factors of epidemiology, high risk pregnant women, fetus and high-risk newborns that relate to pyelectasis were summarized. High-risk factors were analyzed by using logistic multivariate regression analysis. Results: Of 960 high-risk infants, 103 had abnormal urinary ultrasound results, 87 (9.1% of high-risk infants) were diagnosed with pyelectasis, 16 (1.7% of high-risk infants) were diagnosed with congenital anomalies of the kidney and urinary tract. According to the degree of pyelectasis, 68 infants were Grignon grade Ⅰ, male:female ratio=5.8∶1, left side:right side ratio=1.91∶1; 19 infants were Grignon grade Ⅱ, male:female ratio=5.33∶1, left side:right side ratio=2.12∶1. Postnatal follow-up results showed that pyelectasis disappeared in 48 cases (55% of pyelectasis cae), 40 infants were Grignon grade Ⅰ (59% of all Grignon grade Ⅰ patients), 8 infants were Grignon grade Ⅱ (42% of all Grignon grade Ⅱ patients); The result of risk factors analysis showed that the risk of pyelectasis in males was 4.368 times that of females (95%CI: 2.33-8.189, P<0.05); the risk of pyelectasis in low birth weight infants was 22.434 times that of non low birth weight infants (95% CI: 5.883-85.547, P<0.05). Conclusion The incidence of pyelectasis in high-risk infants was 9.1%. The mitigation rate of pyelectasis in Grignon grade Ⅰ to Ⅱ in fetal or newborn period is high. Patients in Grignon grade Ⅲ and above in fetal or new born period had high risk of congenital anomalies of the kidney and urinary tract. The risk of pyelectasis of male was higher than that of female; the risk of pyelectasis of low birth weight infant was higher than appropriate for gestational age infants.

Objective To understand the radiation protection effect of pre-irradiation administrations of nilestriol on the mice with bone marrow type of acute radiation syndrome after irradiation with 60Co γ-rays,along with its mechanisms for improvement of hematopoiesis.Methods The nilestriol administration protocols were prepared by analysis of peripheral blood cell counts and survival rate experiment on mice.The mechanisms by which the pre-irradiation twice administrations improved the post-irradiation recovery of bone marrow hematopoiesis were studied by the analysis of the surface marker of bone marrow hematopoietic stem/progenitor cells of mice and by the inspection of hematopoietic progenitor cell colony and by using histopathological assessment of bone marrow.Results Pre-irradiation administration of nilestriol at two-or three-day intervals had been shown to increase survival rates up to 100％ in mice exposed to 9.0 Gy γ-rays,which was superior to a single administration (20％,x2 =21.66,21.66,P ＜0.05).The pre-irradiation administration both at one-day or two-day intervals were capable of improving the recovery of peripheral blood counts,including white blood cell (WBC),red blood cell (RBC),and platelet in mice exposed to 6.5 Gy (F =21.33,100.9,49.34,19.19,P ＜ 0.05),showing the better effects than a single administration (F =17.11,63.38,21.89,14.37,P ＜ 0.05).The two-day-interval administration of nilestriol could significantly increase the numbers of bone marrow hematopoietic stem/progenitor cell counts (t =8.58,2.80,P ＜ 0.05) in mice on day 10 after 6.5 Gy irradiation.This also could be capable to significantly improve colony formation,with there being statistical difference compared with single administration(t =4.29,6.34,P ＜ 0.05).Also the administration at two-day-interval were also usefull in reconstruction of hematopoietic cell hyperplasia of bone marrow of irradiated mice.Conclusions As compared with conventional single admination,the pre-irradiation multiple administrations of nilestriol showed significantly improved radiation protection effects.Considering a nuclear medical emergency rescue,it is recommended to follow the pre-irradiation administration of nilestriol at two-day interval,which could obtain the best protection effects at minimum administration frequency.
