ObjectiveTo observe the clinical efficacy and safety of Bushen Ruyan Formulation （补肾乳岩方， BRF） in treating premenopausal breast cancer patients of disharmony of the chong （冲） and ren （任） meridian type under endocrine intensive therapy. MethodsA total of 88 premenopausal breast cancer patients who received endocrine intensive therapy and were diagnosed with disharmony of the chong and ren meridian by traditional Chinese medicine （TCM） were included and randomly divided into a control group and a treatment group， with 44 cases in each group. The control group received ovarian function suppression （OFS） combined with endocrine therapy， while the treatment group was given oral BRF additionally. Both groups were treated for three months. The clinical efficacy was evaluated by comparing the pre- and post-treatment results of the Functional Assessment of Cancer Therapy-Breast （FACT-B）， modified Kupperman score， T cell subsets （CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺）， sex hormone levels， including estradiol （E₂）， luteinizing hormone （LH）， follicle-stimulating hormone （FSH）， progesterone （P）， testosterone （T）， and prolactin （PRL）， tumor markers， such as carcinoembryonic antigen （CEA）， carbohydrate antigen 125 （CA125）， and carbohydrate antigen 153 （CA153）， TCM syndrome score， and TCM syndrome efficacy. Blood routine tests， liver function and kidney function were monitored to assess safety. ResultsThe FACT-B scores of each domains and the total scores of the treatment group increased， while the social/family status score of the control group decreased. The treatment group had significantly higher scores in all domains and total score compared to the control group （P＜0.05 or P＜0.01）. The modified Kupperman score and TCM syndrome score of the treatment group decreased， and were lower than those of the control group （P＜0.01）. The levels of CD3⁺ and CD4⁺ in the treatment group increased， and were higher than those of the control group （P＜0.05）. Serum testosterone levels in the treatment group were lower than those in the control group （P＜0.05）. The total effective rate of TCM syndrome efficacy in the treatment group was 67.44%， significantly higher than the 23.26% in the control group （P＜0.05）. No significant abnormalities were observed in the blood routine tests or liver/kidney function indicators in either group before or after treatment. ConclusionBRF can effectively improve quality of life， alleviate symptoms， increase serum CD3⁺ and CD4⁺ levels， and enhance clinical efficacy in premenopausal breast cancer patients undergoing endocrine intensive endocrine therapy. It is also safe with no significant adverse effects.

Objective:To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL).Methods:A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children′s Hospital, Capital Medical University and Baoding Children′s Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients.Results:Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) ( χ2=1.88, 1.47, P=0.170, 0.224). Conclusions:Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

Objective:To retrospectively analyze the gender differences in the clinical characteristics and perioperative outcomes of patients with type A aortic dissection in our institution.Methods:From January 2019 to January 2020, total 405 patients underwent surgical treatment for type A aortic dissection at Beijing Anzhen Hospital, including extensive aortic repair (total aortic arch replacement combined with stenting elephant trunk implantation) and limited aortic repair. In the entire cohort, male 295 cases, female 110 cases. All measures in this study were expressed as ± s or median(quartiles) and analyzed by Student t test for variables or non- parametric tests; count data were expressed as frequencies and percentages and analyzed by χ2 test and Fisher exact probability test. Independent risk factors were analyzed by logistic multivariate regression. Results:Females were older than males[(53.3 ± 12.4)years old vs. (47.1 ± 11.0)years old, P<0.001] and had significantly higher proportion of diabetes(9.1% vs. 4.1%, P=0.047) and previous cerebrovascular disease (11.8% vs. 5.8%, P=0.038). Females had a lower proportion of total aortic arch replacement combined with elephant trunk implantation (64.5% vs. 82.7%, P<0.001), while aortic cross-clamp time[168.0(144.8, 201.5) minutes vs. 190.0 (163.0, 217.0) minutes, P<0.001] and CPB time[99.0 (79.8, 118.0) min vs. 107.0 (91.0, 126.0) min, P=0.006] were significantly shorter than males. Females had significantly higher rates of pulmonary infection (14.5% vs. 5.8%, P=0.004) and stroke than males (15.5% vs. 8.1%, P=0.030). The difference in the proportion of postoperative deaths between female and male TAAD patients was not statistically significant (3.6% vs. 7.8%). Logistics multivariable regression analysis found that female was an independent risk factor for postoperative stroke ( OR=2.574, 95% CI: 1.198-5.531, P=0.015) and pulmonary infection ( OR=2.610, 95% CI: 1.180-5.772, P=0.018). Conclusion:Gender did not affect mortality after TAAD repair significantly, but females increased the risk of stroke and pulmonary infection after TAAD surgery.

Objective To investigate the effect of acupuncture on fatigue improvement and gut microbiota in mice with cancer-related fatigue(CRF),and explore its possible mechanism of action.Methods The mice model of CRF of breast cancer after chemotherapy was established by tumor bearing and chemotherapy.After acupuncture intervention,fatigue was evaluated by general condition,forced swimming and open field experiment.Then 16S rDNA sequencing was used to analyze the structural abundance of gut microbiota in mice.Results Acupuncture could significantly improve the fatigue degree and general condition of the mice model of CRF of breast cancer after chemotherapy.At the same time,acupuncture could adjust the abundance of gut microbiota structure,up-regulate the abundance levels of Lactobacillus,Bacteroides,firmicutes,actinobacteria,and down-regulate the abundance levels of Proteobacteria and Staphylococcus.There were also differences in the abundance of flora structure among the groups,but the abundance of beneficial bacteria was relatively high in the acupuncture group,and the abundance of pathogenic bacteria was relatively high in the other two groups.Conclusion Acupuncture may play a role in the treatment of CRF by regulating the abundance of gut microbiota structure,increasing intestinal beneficial bacteria,inhibiting pathogenic bacteria,improving body immunity,and alleviating adverse reactions caused by chemotherapy for breast cancer.

Objective:To analyze the long-term outcomes of hybrid arch repair(HAR) treating aortic arch pathologies.Methods:Between January 2009 and January 2018, 87 consecutive patients underwent HAR for aortic arch pathologies at Beijing Anzhen Hospital. 76 were males. 2 cases were in zone 0, 46 cases were in zone 1, and 39 cases were in zone 2. The zones of the aortic arch were defined following the Ishimaru classification.Results:Five(5.7%) operative death occurred. 13 patients(19.1%) died during the follow-up. The overall survival rate was 88.4%, 83.3%, 83.3%, 49.8% at 1, 3, 5, 10 year, respectively. Multivariate Cox proportional risk analysis showed that stroke( HR=20.626, 95% CI: 2.698-157.685, P=0.004) was an independent risk factor for short-term death. Stroke( HR=16.234, 95% CI: 4.103-64.229, P<0.001) and spinal cord infury( HR=11.060, 95% CI: 2.150-56.893, P=0.004) were independent risk factors for long-term death. Conclusion:In conclusion, HAR could be an alternative procedure for the patients that are not suitable for open repair under the premise of strict control of indications. In the future, the risk assessment system and uniform operational indications for HAR should be further established.

Objective:To evaluate the reliability and validity of the Chinese version of the Orebro musculoskeletal pain questionnaire (OMPQ-CHN) using patients with non-specific lower back pain.Methods:The OMPQ was translated into simplified Chinese according to the Beaton cross-cultural translation guidelines, and then 186 patients with acute or subacute lower back pain were asked to respond to its questions. Based on the results, the internal consistency and test-retest reliability were quantified, and its validity was assessed using content, criterion-related and predictive validity.Results:The Cronbach′s α for the instrument was 0.804. Its ICC was 0.833 (95% CI: 0.683-0.915). I-CVI ranged from 0.86 to 1, S-CVI/Ave=0.99. The correlation between the OMPQ-CHN and other questionnaires ranged from r=0.419 to r=0.646. The AUCs predicting pain, dysfunction and sick leave ranged from 0.723 to 0.810. Conclusions:The OMPQ-CHN has good reliability and validity, and suitably assesses the psychosocial risk factors of Chinese patients with low back pain.

Objective:To summarize the surgical treatment strategy for aortic injury caused by trauma.Methods:From January 2009 to January 2018, 34 patients with TAI were treated in Beijing Anzhen Hospital. 10 had hypertension. 23 cases were males. There were 31 cases caused by traffic accidents, 2 cases were fall injuries, and 1 case was bruise. 9 cases were thoracic aortic pseudoaneurysm, 6 cases were thoracic aorta, and 19 cases were aortic dissection. 29 patients underwent TEVAR and 5 patients underwent OR (2 patients with type A aortic dissection undergoing Bentall + Sun's procedure, 1 patient with type B aortic dissection and 2 patients with thoracic aortic pseudoaneurysm undergoing stented elephant trunk procedure).Results:The follow-up time was (45.09±23.10) months. The mean age of patients undergoing OR or TEVAR was (44.80±20.57) years old, (45.93±11.01) years old; the mean operation time was(403.20±30.30) minutes, (105.72±27.76) minutes; the mean hospitalization (19.00±6.04), (5.76±3.08) days. There were no deaths in the two groups. 2 patients uundergoing TEVAR had left upper limb numbness.Conclusion:The treatment of patients with TAI should be based on the general condition, the classification of injury, the involving regions and anatomical features to choose different treatments. In addition, the long-term prognosis of patients remains to be determined.

Objective:Acute type A dissection with mitral regurgitation was very rare. To sum up our experience of surgical treatment of acute type A dissection with mitral regurgitation.Methods:From October 2010 to January 2017, 17 patients with acute type A dissection with mitral regurgitation underwent surgical treatment. There were 12 males, 5 females; mean age, (38±11) years(range, 18-59 years). Hypertension was noted in 9 patients, Marfan syndrome in 2 patients, renal dysfuction in 3 patients, cardiac dysfunction in 3 patients, lower limb ischemia was observed in 2 patients and dilated cardiomyopathy in one patient.

Continuous renal replacement therapy was required in 3 patients, re-operation in one patient and partial pericardial excision in one patient. One patient was out of follow-up. The remaining had a normal life during follow-up.Conclusion:Repair of acute type A dissection with mitral regurgitation carried with a relatively high mortality and morbidity. Under better protection of heart and cerebrum, it obtained accepted surgical results in patients with this lesion

Objective: To observe the changes in nutrition indicators and the effect on chemotherapy complications as well as the safety of enteral nutrition by way of providing enteral nutrition support for children with acute lymphoblastic leukemia (ALL) at the stage of induction chemotherapy. Methods: From November 2016 to September 2017, 60 children with newly diagnosed ALL at the Hematology Oncology Center of Beijing Children′s Hospital were enrolled in this study.They were randomly divided into an experimental group and a control group, 30 cases for each group.The experimental group was given a high-calorie diet, high-quality protein, and high-medium-chain trigly-ceride enteral nutrition on the basis of a conventional low-fat diet, and the duration lasted the whole induction treatment of ALL children; while the control group was given a low-fat diet routinely.By analyzing relevant indicators before induction chemotherapy (D0), chemotherapy day 15 (D15), and after chemotherapy (D33), the changes in nutritional status and the effect on chemotherapy complications in 2 groups were investigated. Results: There was no significant difference in the body mass index (BMI) and the thickness of triceps skinfold between 2 groups before and after chemotherapy (all P>0.05). The upper arm circumference increased after chemotherapy in the experimental group[before treatment: (15.80±2.63) cm, after treatment: (16.27±2.57) cm], while that of the control group decreased slightly[before chemotherapy: (17.19±3.71) cm, after chemotherapy: (17.15±3.64) cm], and the difference between 2 groups was statistically significant (P<0.05). After chemotherapy, the total protein levels in two groups decreased[the experimental group: (64.52±4.85) g/L, the control group: (61.97±4.65) g/L] which was significantly different from that before chemotherapy [the experimental group: (68.17±6.37) g/L, the control group: (68.08±5.14) g/L] (P<0.01). The total protein level of the experimental group after chemotherapy was significant higher than that in the control group (P<0.05). Both albumin levels in 2 groups increased after chemotherapy [(42.45±4.32) g/L in the experimental group and (41.15±3.73) g/L in the control group], and there was a significant difference between 2 groups before chemotherapy [(39.54±3.26) g/L in the experimental group and (40.01±4.37) g/L in the control group] (P<0.05). The level of prealbumin increased after chemotherapy in both groups [(324.57±64.328) mg/L in the experimental group and (293.07±69.09) mg/L in the control group] compared with that before chemotherapy [(121.10±35.13) mg/L in the experimental group and(131.20±52.77) mg/L in the control group]. The change was statistically significant (P<0.01). The albumin level in the experimental group before chemotherapy was lower than that in the control group after chemotherapy, but it was higher than that in the control group after chemotherapy.Protein differences were statistically significant (P<0.05). The reduction rate of elemental iron in the experimental group after chemotherapy was lower than that in the control group, but it was not statistically significant (P>0.05). Elemental zinc was not significantly different compared with the control group.The incidence of neutropenia after chemotherapy in ALL children was higher (37/60 cases, 61.67%). The recovery of neutropenia after chemotherapy in the experimental group was better than that in the control group.After chemotherapy, the severity of anemia in the experimental group was lighter than that in the control group.The amount of blood transfusion required and amount of transfusion per capita were less than those in the control group (54 person-times vs.74 person-times, 2.45 times vs.3.08 times). The total number of transfused blood products was less than that of the control group (78 person-times vs.101 person-times), but none of the findings above were statistically significant (all P>0.05). The degree of hepatic damage in the experimental group decreased after chemotherapy, but there was no significant change in the control group.The initial activated partial thromboplastin time(APTT) prolongation in the trial group was more than that in the control group (5 cases vs.3 cases), and less than the control group (0 case vs.1 case) after chemotherapy.The frequency of fever in the experimental group during chemotherapy was less than that in the control group (6 cases vs.8 cases), and the average time of fever was shorter than that in the control group (2.8 d vs.4.1 d). None of the above findings were statistically significant (all P>0.05). During the course of chemotherapy, 0 pancreatitis occurred in the experimental group, and 1 pancreatitis occurred in the control group.There was no difference in remission rates between 2 groups of chemotherapy for 15 days and chemotherapy for 33 days. Conclusions The nutritional status of children with ALL was reduced after initial induction chemotherapy.Enteral nutrition support was helpful to maintain the nutritional status for children at the initial stage of chemotherapy, high-calorie diet, high-quality protein, and high-medium-chain triglyceride enteral nutrition support improves blood system tolerance to chemotherapy and reduces chemotherapy complications.

Objective To investigate the efficacy of blood purification for acute lymphoblastic leukemia pediatric patients with high-dose methotrexate (MTX)-induced hypermethotrexemia and acute kidney injury (AKI). Methods The clinical data of 50 acute lymphoblastic leukemia pediatric patients with hypermethotrexemia (the 45th hour MTX blood concentration ＞20 μmol/L) and AKI who were admitted to Beijing Children's Hospital Capital Medical University from May 2010 to August 2018 were collected. After the treatment of blood purification, the declining rate of MTX concentration, the incidence of drug-related side effects and the clinical transition were analyzed retrospectively. Results The median MTX blood concentration at the 45th hour after high-dose MTX chemotherapy was 31.5 μmol/L (20.0-80.3 μmol/L). After blood purification treatment, 48 patients (96%) survived, 1 patient (2%) died, and 1 patient (2%) gave up treatment. It costed 10.0 days (7.0-15.0 days) to decline the MTX concentration to the normal level by using blood purification. The median time of purification was 32.5 hours (2.0-168.0 hours), and the days of dialysis were 3.0 days (1.0-9.0 days). The AKI occurred in approximately 96% (48/50) of patients, which was the main side effect. The time of declining the high MTX concentration to the normal was positively correlated with the increase times of serum creatinine (r ＝ 0.371, P＝ 0.009) and urea nitrogen (r ＝ 0.486, P＝ 0.001), and the value of the alanine aminotransferase (r ＝0.364, P＝0.010) and gamma glutamyl transpeptidase (r ＝ 0.344, P＝ 0.010), and the days of dialysis (r ＝ 0.532, P < 0.01), but there was no relationship with the 45th hour MTX blood concentration (r＝0.110, P＝0.248). The reduction of MTX blood concentration from the 45th hour to the 69th hour after high-dose MTX chemotherapy was negatively correlated with the increase times of urea nitrogen (r ＝ -0.336, P＝ 0.009) and serum creatinine (r ＝ -0.260, P＝ 0.035). Conclusion When the MTX blood concentration of patients with hypermethotrexemia and AKI couldn't be declined to the normal level by using high-dose leucovorin, hydration and alkalization, and without the effective detoxification drug (carboxypeptidase G2), they should be offered blood purification, especially continuous renal replacement therapy as soon as possible, which can reduce the blood concentration of MTX quickly and decrease the incidence of side effects effectively.
