To investigate the feasibility of in vitro inducing differentiation of bone marrow stromal cells (BMSCs) into neural stem cells and mature neural cells, and to offer reference for the application of BMSCs in the field of neuroscience, BMSCs were acquired from the marrow of dogs. Basic fibroblast growth factor (bFGF), all trans retinoic acid (RA) and glial cell line derived neurotrophic factor (GDNF) etc were used as proliferation or differentiation factors. Immunocytochemistry was employed to identify the cells at every culture stage. When BMSCs were proliferatively cultured for 24~72h, cleavage phase and cluster like clones appeared. On the 3rd day, some of the BMSCs derived cells started to express neuron specific enolase (NSE) or glial fibrillary acidic protein (GFAP). The same stage cells could be cloned, that is one of the characters of stem cells, when they were cultured in the proliferation medium. The neural cell modality like cells appeared on the 10th day after adding inducing factors into culture medium, which were proved by testing the express of NSE and GFAP. BMSCs can differentiate into neural stem cells and mature neural cells in vitro, and can be used as "seed cells" in the field of neuroscience.

Objective To explore cancer factor exhausted during chemotherapy intermittent for drinking, food and oxygenic sport interference to patients suffered from ovarium cancer. Method 92 patients suffered from ovarium cancer with drinking, food and oxygenic sport interference and taking self-comparison method. Simple tired Assessment Form, European cancer treatment and research origination questionnaire (EORTC-QLQ-C30) are as-sessed for the patients suffered from cancer tied and life quality situation before interference and after interference of 30 d so as to observe the tired relieving degree and life quality of the patients before and after interference. Results Using nursing interference and then the patients relive their tiredness greatly to have statistical significance (P <0.01). The comparison before and after interference and the life quality has statistic significance(P <0.01). Con-clusion The drinking, food and oxygenic sport interference can relieve the fired degree of the patients suffered from ovarium cancer effectively to improve the life quality of the patients.

Objective To investigate the hemostatic effect and influence on coagulation function of hemecongulase during neurosurgical operation.Methods Sixty patients with neurosurgical trauma at American statistical association(ASA) Ⅰ-Ⅱ were randomly divided into hemocoagnlase treatment group (n =30) and control group(n =30).Both two group were injected Baquting 2U at the day before the operation,30 min before the operation,every two day after the operation and end up 3 d.Treatment group were pedormed with Baqyting 4 U + physiological saline 10 ml topical spraying.The intelligibility of operating region,the volume of intraoperative,the volume of bleeding during the operation,transfusion of blood,postoperative drainage,and drainage tube exelcymosis time were recorded in all the patients.Prothrombin time (PT),activated partial thromboplastin time (APTT),fibrinogen level(FIB),fibrinogen degradation product(FDP) and the two D-dimer and platelet count(PLT) before and after the surgery were also determined.All the patients were postoperatively followed up.Results The intelligibility of operating region was 70.0% (21/30) in the hemocoagnlase treatment group,higher than that in control group (0%,P <0.05).The volume of bleeding during the operation in the hemecoagulase treatment group was (680.00 ± 95.22) ml,significantly fewer than that in the control group((790.00 ±47.00) ml,P =0.034).PLT significantly decreased after the surgery in both of the groups compare to that in preoperation (P < 0.05 or P < 0.01) and no significant difference was seen between two groups (P > 0.05).No severe adverse events were found in both groups.Conclusion Hemocoagulase treatment during the operation can improve the intelligibility of operating region,reduce the volume of bleeding and transfusion of blood,and do not affect the coagulation function in the patients.Therefore,hemocoagulase is a safe and effective hemostatic and through local application during the operation it can improve curative effect.

Objective:To investigate the association between pelvic bone dose-volume parameters and acute bone marrow suppression in cervical cancer treated with concurrent cisplatin and intensity-modulated radiation therapy, in order to provide the limited prescription for making radiotherapeutic plan.Methods:The clinical data of 40 cervical cancer patients receiving cisplatin with concurrent intensity-modulated radiation therapy in the Affiliated Hospital of Ningde Normal College from November 2017 to January 2020 were analyzed. The correlations of the irradiated volume of pelvic bone receiving doses of 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 Gy as a percentage of the total volume of pelvic bone (V 5 Gy,V 10 Gy, V 15 Gy,V 20 Gy,V 25 Gy, V 30 Gy, V 35 Gy, V 40 Gy, V 45 Gy, V 50 Gy), the maximum dose (D max), the minimum dose (D min), and the mean dose (D mean) with the occurrence of ≥grade 3 acute bone marrow suppression were analyzed. The logistic multiple regression analysis was used to study the influencing factors of ≥grade 3 acute bone marrow suppression, and the receiver operating characteristic (ROC) curve was used to determine the diagnostic efficacy of influencing factors for ≥grade 3 acute bone marrow suppression. Results:The incidence rate of ≥grade 3 acute bone marrow suppression was 47.5% (19/40). Between patients with ≥grade 3 and

This study was purposed to investigate the molecular basis for RhD negative phenotype in Yiwu population in Zhejiang Province of China. The RhD negative samples were screened by saline agglutination test in blood donors. Some real RhD negative and RhDel phenotypes were identified using anti-human globulin test and absorbtion elution test. Ten exons of RHD gene in these samples were amplified by PCR-SSP, and positive exons were DNA sequenced. The results indicated that 30 real RhD negative and 8 RhDel phenotypes were identified in 38 initial RhD negative samples. Ten exons were complete negative in 28 real RhD negative samples and only exon 1, 2 and 10 were positive in 2 real RhD negative samples amplified by PCR. All 10 exons in 8 RbDel samples were positive and a DNA variant (1227G > A) was found in 8 RhDel samples. It is concluded that all exons are absence in most real RhD negative phenotypes, and the partial exons absence is also found in some real negative phenotypes among Yiwu population in Zhejiang province of China. The G to A mutation at position 1227 is found in all RhDel phenotypes.

OBJECTIVE:
To explore the genetic basis for a child featuring hypotonia, ataxia, and delayed development syndrome (HADDS).
METHODS:
Whole exome sequencing was carried out for the child. Candidate variant was verified by Sanger sequencing of the child and his parents.
RESULTS:
The child was found to harbor a de novo heterozygous c.625G>A (p.Arg209Trp) variant of the EBF3 gene, which has caused substitution of Arginine by Tryptophan. The variant may has impaired the binding affinity of EBF3 with DNA and altered its subcellular localization, and ultimately decreased the transcriptional activity of the EBF3 gene.
CONCLUSION
The c.625G>A variant of the EBF3 gene probably underlay the pathogenesis of HADDS in this child. Above finding has expanded the spectrum of EBF3 variants and enriched the clinical manifestations of the HADDS.

Objective For decreasing the infected rate,the prevention and cure methods of intracranial infections following posterior fossa craniotomy were study. Methods Twenty-eight patients with the intracranial infections following posterior fossa craniotomy were examined by lumbar puncture,and analyzed cerebrospinal fluid with routine examination and reference to the bacteriological data and drug sensitive tests. All the patients were treated with high dosage sensitive antibiotics, and draining continually the infected cerebrospinal fluid by lumbar puncture catheterization and injected small dosages of antibiotics into intraspinal for most cases. Results Twenty-eight patients had intracranial hypertension by lumbar puncture examination, outcome of cerebrospinal fluid culture indicated that 17 cases had bacteria growth and 11 cases had no bacteria. The intracranial infection was controlled effectively,and 96.4%(27 cases) were cured, 1 case dead of systemic failure. Conclusions Strict aseptic techniques,reduce operative time,decrease intracranial place of foreign matters, such as gelfoam, hemostatic gauze and artificial implants, could reduce the possibilities of intracranial infections. Appropriate antibiotics selection,lumbar puncture catheterization and intraspinal administration of antibiotics can cure intracranial infections effectively.
