BACKGROUND: Diphosphonate has a predominant therapeutic effect in the prevention and treatment of postmenopausal osteoporosis. Ibandronate, as a new-type diphosphonate preparation, is gradually becoming a study hotspot.OBJECTIVE: This study is to investigate the efficiency of ibandronate in interfering postmenopausal osteoposis by observing bone mass loss related indexes in ovariectomized rats, and made a comparison with nilestriol.DESIGN: A completely randomized grouping, and controlled animal experiment.SETTING: Study Room for Bone metabolism, Fudan University Medical College.MATERIALS: Forty SD female rats, aged 10-12 months, were involved in this study. Ibandronate was provided by the State Key Laboratory of Jiangsu Institute of Atomic Medicine. Nilestriol was produced in the Shanghai 12th Pharmaceutical Factory.METHODS: This experiment was carried out in the Study Room for Bone Metabolism, Institute of Radiation Medicine,Shanghai Medical University between August 1996 and June 1998. The rats were divided into 4 groups by a lot, 10 rats in each: sham-operation group, ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group. In the sham-operation group, only small pieces of adipose tissue around the ovary were resected from the rats.Three months after operation, each rat was intragastrically administrated with 1 mL normal saline; In the ovariectomized group, ovariectomized+ibandronate group and ovariectomized +nilestriol group, each rat was subjected to bilateral ovariectomy, and 3 months later, they were intragastrically administrated with normal saline, ibandronate water solution [0.5 mg/( kg·d)] and nilestriol suspension [1 mg/(kg· time)] respectively. Each rat in the latter three groups was administrated for 90 days, twice in the first week, and then once a week.MAIN OUTCOME MEASURES: Left femur was taken out, and its dry weight and ash weight were measured. Calcium content of bone was determined with an atomic absorption spectrophotometer, bone density of the whole body with a bone density apparatus, the bone density at the juncture of 1/2 right femoral bone length with a single photon bone density apparatus, and femoral anti-bending force was determined with a universal testing machine. Alkaline phosphatase were determined by dynamical method with an automatic biochemistry analyzer, urine calcium by EDTA titration method, urine creatinine by picric kinetic method, and urinary hydroxyproline by modified proline assay.Trabecular area was calculated.RESULTS: Forty rats were involved in the final analysis. ① Bone dry weight, bone ash weight and bone calcium content in the ovariectomized group were significantly lower than those in the other 3 groups, respectively (t =13.58-52.98, P ＜0.05). ② Femoral bone density and bone density of the whole body of rats in the ovariectomized group were significantly lower than those in the other 3 groups (t =3.31-5.61, P＜0.05), while anti-bending force was close between ovariectomized group and the other 3 groups (P＞0.05). ③ The ratio of urine calcium to urine creatinine was significantly lower in the ovariectomized+ibandronate group and ovariectomized +nilestriol group than in the ovariectomized group (t =4.04, 3.30, P＜0.05). No significant difference in the alkaline phosphatase and ratio of urinary hydroxyproline to urinary creatinine existed among the groups (P ＞ 0.05). ④Trabecular area of vertebrae in the ovariectomized group was significantly smaller than that in the other 3 groups (t =2.22,2.41,3.45,P ＜ 0.05), while the trabecular area of tibia in the ovariectomized group was only smaller than that in the ovariectomized +nilestriol group (t =2.45, P＜ 0.05).CONCLUSION: Osteoporosis apPears obviously in the SD rats 3 months after ovariectomy. Ibandronate has obviously inhibitory effects on the bone mass loss of rats with postmenopausal osteoposis, and it is equivalent to nilestriol in inhibitory effect.

Objective:To investigate the application of system relaxation training on the posttraumatic stress disorder for the families of burned children, so as to provide a basis for the application of valid nursing in children families.Methods:A total of 80 cases of burned children in Children′s Hospital of Nanjing Medical University and corresponding 80 households were recruited and divided into the observation group and the control group with 40 cases each group. The patients and households from January 2019 to May 2019 in the control group received routine care, while the patients and households from February 2020 to June 2020 in the observation group received system relaxation training based on the routine care for four days. The posttraumatic stress disorder and uncertainty in illness of children families before and after intervention were evaluated by Posttraumatic stress Checklist-Civilian version(PLC-C) and Mishel Uncertainty in Illness Scale-Family Member form(MUIS-FM) and compared between the two groups.Results:There was no significant difference in the scores of PLC-C and MUIS-FM before intervention in the households between the two groups( P>0.05). After intervention, the scores of re-experiencing symptoms, avoidance/numbing, increased arousal symptoms and total PTSD scores in the households were (8.40 ± 1.79), (14.35 ± 2.85), (8.25 ± 1.28), (31.10 ± 3.52) points in the observation group and (11.28 ± 2.37), (16.75 ± 2.09), (9.10 ± 1.93), (37.13 ± 4.40) points in the control group, the differences were statistically significant ( t values were -6.76 - -2.32, all P<0.05). After intervention, the scores of ambiguity, deficit information and total MUIS-FM scores of the households were (37.08 ± 6.58), (20.15 ± 4.38), (84.38 ± 6.90) points in the observation group and (41.13 ± 6.54), (22.05 ± 3.32), (90.13 ± 7.85) points in the control group, the differences were statistically significant ( t =-2.76, -2.19, -3.48, all P<0.05). Conclusions:System relaxation training can alleviate posttraumatic stress disorder and reduce uncertainty in illness of the families of burned children.

Objective:To explore the efficacy and safety of blinatumomab in treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL).Methods:The data of 8 patients with relapsed/refractory B-ALL treated with blinatumomab in Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from September 2020 to December 2021 were retrospectively analyzed, and their clinical characteristics, overall survival, lymphocyte subsets, cytokines, tandem transplantation and adverse reactions were analyzed.Results:The median follow-up time of 8 patients was 143 d (range: 41-534 d). Five of the 8 patients were alive; among them, 4 of 6 patients assessed to be in minimal residual disease (MRD)-negative complete remission (CR) and 1 of 2 patients assessed to be in non-remission at the time of belintuzumab discontinuation were alive. The median duration of treatment with belintuzumab was 28 d (10-56 d), and it was 23 d (10-56 d) for patients with MRD-positive at baseline and 28 d (25-31 d) for the 4 non-remission patients. Six patients achieved MRD-negative CR after treatment, of which 4 were assessed as MRD-positive at baseline and 2 were assessed as non-remission at baseline. All 4 patients with MRD-positive CR achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Philadelphia chromosome-positive (Ph +) ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph + ALL and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation and had persistent MRD-negative CR. Two of the 4 non-remission patients achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Ph + ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation, and the 2 patients had persistent MRD-negative CR. Leukocyte counts and neutrophils decreased in both MRD-positive CR and non-remission patients after receiving belintumomab. The proportion and absolute number of CD3 + T and CD3 + CD8 + T lymphocytes in patients with MRD-positive CR were higher than those in patients without remission, and both decreased after drug administration. Median interleukin-6 (46.23, 1.42 pg/ml), interleukin-8 (17.85, 2.10 pg/ml), interleukin-10 (7.43, 1.49 pg/ml) and interferon-γ (11.82, 0.39 pg/ml) levels were elevated in MRD-positive CR and non-remission patients at week 3 of treatment. Grade 1 cytokine release syndrome occurred in 1 case with clinical manifestations of fever, which improved after drug suspension. Three cases developed infections, 2 of which were pulmonary and 1 of which was upper respiratory tract infection. No immune effector cell-associated neurotoxic syndrome was observed. Conclusions:Belintumomab is effective for MRD clearance in relapsed/refractory B-ALL with manageable adverse reactions, providing an effective therapeutic option for bridging hematopoietic stem cell transplantation to prolong the survival of patients.

【Objective】 To study the protective effect of glycine solution on frozen red blood cell thawing process. 【Methods】 A total of 20 bags of 1 U of leukocytes reduced suspended red blood cells within 6 days were selected for the study. After mixing, each 2 bags of suspended red blood cells were divided into 2 bags and into two groups with 10 bags of 1 U in each group, and were frozen for storage. One group was deglycerolized with sodium chloride solution (control group), and one group was deglycerolized with glycine solution (experimental group). The hemoglobin, free hemoglobin, residual glycerol, total glycerol in red blood cells, adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG) were detected in the two groups. 【Results】 Compared with the free hemoglobin content (0.90±0.05)g/L and residual glycerol content (1.17± 0.08)g/L in the control group, the final product red blood cell supernatant free hemoglobin content (0.77±0.15)g/L and residual glycerol content (0.79±0.33)g/L in the experimental group were decreased, and the difference was statistically significant (P<0.05). Compared with the ATP content (4.03±0.38)µmol/gHb and 2,3-DPG content (485.65±78.08)µg/L in the control group, the ATP content (4.41±0.35)µmol/gHb and 2,3-DPG content (656.28±116.68)µ g/L in the experimental group were significantly increased, with statistical significance (P<0.05). 【Conclusion】 Using glycine solution instead of sodium chloride solution to prepare frozen thawed deglycerolized erythrocytes achieved the effect of protecting erythrocytes, reduced the hemolysis rate of erythrocytes and glycerin residue, and increased the recovery rate of erythrocytes.
