ObjectiveTo investigate the effect of SalB on bone marrow-derived mesenchymal stem cells (BMSCs) apoptosis induced by hypoxia and serum deprivation (hypoxia/SD) in the vitro. Methods BMSCs were cultured in the vitro and randomly divided into control group, hypoxia/SD group and SalB group.SalB group was composed by four groups and were pretreated by complete medium with 0.1、 1、 10、 100 mg/L SalB for 1 hour. And after that they were washed with phosphate buffer for 2 times, added by IMDM with 0.1、1、 10、 100 mg/L SalB and cultured with hypoxia/SD group together in the same condition of hypoxia/SD for 6hours. The control group was cultured for 6 hours in the condition of aerobic and enough serum. Apoptosis was detected by Hoechst33342 staining with inverted phase contrast, fluorescence microscope and Annexin V/PI dual-color flow cytometry. Results Significant apoptosis of BMSCs was induced by hypoxia/SD in the vitro.The early apoptosis of BMSCs induced by hypoxia/SD was significantly decreased by SalB of 0.1、 1、 10 mg/L(P＜0.05) . Conclusion0.1、 1、 10 mg/L SalB can decrease the early apoptosis of BMSCs induced by hypoxia/SD.

Objective To study the pathogenesis, clinical characteristics, laboratory tests, treatments and prognosis of con-genital factorⅦdeficiency. Methods The clinical data of two cases of congenital factorⅦdeficiency diagnosed at the Chil-dren’s Hospital of Fudan University and 9 cases reported in the past 10 years retrieved from Pubmed, Web of Knowledge and CNKI, Wangfang database by using the factorⅦdeficiency , congenital, newborn and case report as keyword were reviewed and analyzed. Results All cases were full term birth with normal birth weight (>2 500 g), including 4 females and 7 males. Pa-rental consanguinity was found in 3 cases, and a family history was found in 3 cases. The laboratory tests were characterized by significantly prolonged prothrombin time, normal partial thromboplastin time, and decreased coagulation factorⅦactivity. The coagulation factorⅦactivity of 10 cases were less than 5%. Five cases (45.5%) were treated with human recombinant activated factorⅦ. Four cases (36.4%) treated with plasma or human recombinant activated factorⅦare currently in normal growth and development. Four cases (36.4%) died during the hospitalization. Conclusions A diagnosis of congenital factorⅦdeficiency should be considered in the neonates with severe bleeding, prolonged prothrombin time, normal partial thromboplastin time, and being intractable to vitamin K treatment. Human recombinant activated factorⅦis the first choice of the treatment of congenital factorⅦdeficiency. The further study of gene mutation type will be of great significance for disease screening, diagnosis, treat-ment and prognosis prediction.

OBJECTIVE: To analyze and summarize clinical characteristic, treatment scheme and survival rate of primary melanom in nasal cavity and sinus. METHOD: We retrospectively analyzed the 9 patients with primary melanom in nasal cavity and sinus who in data proceed were treated and reviewed the related literature. RESULT: Among the 9 patients, the clinical main symptoms are rhinostegnosis of lateral nasal and intermittent nasal bleeding. Pathologic examination is mainly characterized by tumor cells abnormity and cytoplasm containing pigment or without pigment, and main diagnosis basis is some or all of the positive for HMB45, S-100, melan-A. The survival rate are 88.9% (8/9) of 1-year, 66.7% (6/9) of 3-year and 33.3% (3/9) of 5-year. CONCLUSION The incidence of primary melanom in nasal cavity and sinusis is not frequent in clinic and confirmed by immunohistochemical. The extensive radical excision of focus and combine adjuvant radiotherapy postoperative may improve the survival rate of patients.

Bones are stained into red color with feeding madder, but we do not know whether the fed madder can change the bone biomechanical properties and bone mineral contents in animals. In this research, we established a rat model with feeding madder. The bone biomechanical properties were detected by universal material mechanics, bone mineral contents were detected by inductively coupled plasma mass spectrometry and spectrometer, and red color material in bone was analyzed by high performance liquid chromatography. The results showed that bone biomechanical parameters in femur diaphysis in the 10% and 15% group rats were significantly higher than those in the control group after feeding madder for 6 months. The level of calcium, magnesium and zinc in femur diaphysis in 10% and 15% group rats were higher than those in the control group after feeding madder for 6 months. However, it was shown that the kidney congestion and hyperemia and the level of blood urea nitrogen and creatinine in the 15% group rats were significantly different compared to those in the control group rats after feeding madder for 6 months. The red colored material in bone is related to alizarin analyzed with high-performance liquid chromatography. The conclusion could be drawn that feeding 10% madder in diet was not toxic to the rats fed for 6 months, and it could improve bone biomechanical properties and increase bone mineral elements.

Objective:To explore the effect of peripelvic multi-joint comprehensive exercise in late pregnancy in pregnant women.Methods:From July 2020 to June 2021, 110 first-time pregnant women who were registered at the People's Hospital of Bozhou were selected as the study subject using convenience sampling. According to the random number table method, study subjects were randomly divided into a study group and a control group, with 55 cases in each group. Pregnant women in the study group underwent peripelvic multi-joint comprehensive exercise, while those in the control group underwent routine walking. We compared the adverse events, pain, pelvic ligament elasticity, Bishop score, pregnancy days, and fetal position after exercise between two groups of pregnant women.Results:The study group ultimately included 52 pregnant women, while the control group ultimately included 51 pregnant women. Both groups of pregnant women did not experience abnormal bleeding after exercise. The number of pregnant women in the study group experiencing pain after exercise one day before delivery was lower than that in the control group, with a statistically significant difference ( P<0.05). The pelvic ligament elasticity of pregnant women in the study group during delivery was better than that of the control group, and the Bishop score was higher than that of the control group, with statistically significant differences ( P<0.05). There was no statistically significant difference in the number of pregnancy days between the two groups of pregnant women ( P>0.05). The number of fetuses in the occipital anterior position during admission to labor in the study group was higher than that in the control group, with a statistically significant difference ( P<0.05) . Conclusions:Prenatal multi-joint and deep muscle and ligament exercises through peripelvic multi-joint comprehensive exercise can strengthen the elasticity of the pelvic ligaments in pregnant women, adjust the fetal pelvic entry angle, and reduce the occurrence of post exercise pain, which is worthy of clinical practice.
