1.Clinicopathological characters of basal-like breast carcinoma
Cancer Research and Clinic 2009;21(4):282-285
Basal-like breast carcinoma is a phenotype of breast cancer which was sub-classified according to gene expression profiling criteria, associated with specific pathological features and biological behaviour. These cancer used to be more aggressive and characterized by the absent expression of ER/PR/CerbB-2(triple negative, TG) however positive for basal cytokeratins(basal CK). We present this review to show its pathological characters, clinical progression, prognosis and response to chemotherapy, and provide convenience for pathologists and surgical colleagues be more aware of this subtype.
2.Extracorporeal shock wave therapy plus enhanced load fibrin glue bone growth factors for nonunion or delayed osseous union of rabbit
Chinese Journal of Immunology 2015;(9):1186-1190,1194
Objective:To evaluate the effect of Extracorporeal Shock Wave combined percutaneous injection of enhanced fibrin glue loaded bone growth factor in accelerating the bone nonunion healing and promoting osteogenesis process .Methods: 48 radius model rabbits were randomly divided into four groups.Group A rabbits were treated with ESW;Group B rabbits were treated with ESW combined with FG;Group C rabbits were treated with ESW combined with FG/rhBMP-2/rhbFGF;Group D rabbits were treated with ESW combined with FG/rhBMP-2/rhbFGF/rhVEGF.After a combination therapy of 8 week,conventional X-ray radiography,optical in-spection organization form and biomechanical test were applied to evaluate the therapeutic effect .Results:Compared with the group B , the X-ray group C showed that the fracture line was fuzzy ,bony callus area began to increased ,fracture end range reduced.The histo-morphology showed that cartilage began to form , cartilage cell began to proliferate actively , and new blood vessels were forming surrounding fibrous connective tissue.Biomechanical determination found there was no statistical significance between the two groups ( P>0.05 ).FG/rhBMP-2/rhbFGF+ESW group showed the fracture line was still fuzzy , bony callus disappeared and apparent proliferative bone trabecula ,and biomechanical results showed that there was statistical significance between the two groups compared to the group B(P<0.01).FG/rhBMP-2/rhbFGF/rhVEGF+ESW group showed the fracture line was slightly fuzzy ,apparent proliferative bone trabecula in 4 week,and in 8 week,the fracture line was disappeared and moulding of healing was good.The histomorphology showed that the distribution was filled with fibrous connective tissue and many bone tissue .Biomechanical results showed that it could resistance to bending ,there was statistical significance between the two groups compared to the group C ( P<0.01 ).Conclusion: ESW therapy combined percutaneous injection of enhanced fibrin glue loaded bone growth factor can promote fracture healing and the method of combination is expected to be a good choice of non-surgical treatment of bone nonunion.
3.Significance of serum B7-H3 in differential diagnosis of obstructive jaundice
International Journal of Surgery 2014;41(10):688-690
Objective To investigated the significance of serum B7-H3 in differential diagnosis of patients with benign and malignant obstructive jaundice.Methods The B7-H3 levels in 60 patients with obstructive jaundice who were divided into benign (32 patients) and malignant (28 patients) obstructive jaundice group were tested by enzyme-linked immunosorbent assay before and after operation.Results The serum B7-H3 levels of malignant obstructive jaundice group were significantly higher than that of benign group (9334.57 ± 1009.57) pg/mL vs (4450.81 ± 406.92) pg/mL,(P < 0.01).The B7-H3 levels of benign and malignant obstructive jaundice group after operation were significantly lower than those before operation (2531.03 ± 415.64) pg/mL vs (4450.81 ±406.92) pg/mL,(5833.00 ± 2190.87) pg/mL vs (9334.57±1009.57) pg/mL,(P<0.01).Conclusion B7-H3 participate in the inflammatory immune and tumor immune response,The serum B7-H3 can be used as differential diagnosis index of benign and malignant obstructive jaundice.

Objective To promote the therapeutic effect about the primary hypertension connected psychological factor through interventing anxiety emotion.Method All primary hypertension patients with anxiety emotion were divided into two groups randomly.Each group was treated by lotension for 8 weeks,While group 1 combined antianxiety drugs Deanxit Result The effective rate of two groups were 93.94%(group 1), 60.61%(group 2).Conclusion The therapeutic effect of group 2 is lower than that of group 1.
7.Study on the decreasing pattern of activities of daily living in patients with dementia
Chinese Journal of Geriatrics 2012;31(5):363-366
Objective To investigate the decreasing pattern of activities of daily living (ADL) in patients with dementia. Methods A total of 204 patients with dementia were collected,among which 106 cases were with Alzheimer's diseases(AD),54 cases with vascular dementia(VD),44 cases with other types of dementia.According to the scores of mini-mental state examination(MMSE),mild,moderate and severe dementia were 42 cases,37 cases and 125 cases,respectively.All of them were assessed by Barthel index(BI) and compared among degrees of dementia,between AD and VD,and levels of education. Results The most reserved items were bowel movement (48.5 %),urination (44.1 %) and grooming (40.2%),while the most vulnerable items were climbing stairs (25.5%) and bathing(18.1%).With increasing impairment of cognition,the scores of BI were getting decreasing. There were significant differences among severe [(23.20 ± 29.27)scores],moderate[(65.54 ± 26.35) scores] and mild [(87.38 ± 22.69) scores] groups (x2 =99.686,P =0.000). Basic ADL were more reserved in AD (16.98%-53.77%) compared with VD (1.85%-33.33%) patients.No significant differences were found(x2 =3.653,P=0.161)among patients with education of primary school and below [(40.1 ± 39.0) scores],middle school[(45.3 ± 39.6 ) scores],and high school and above[(53.1 ± 37.7) scores]. Conclusions Among patients with dementia,bowel control,bladder control and grooming are well reserved,climbing stairs and bathing are vulnerable functions.Basic activities of daily living may be affected by cognitive status and the types of dementia but not levels of culture.

Objective To investigate the effect of Notch1 and Jagged1 on the growth of prostate cancer PC3 cells and the regulation of Jagged1 expression by its receptor Notch1 in PC3. Methods Notch1 and Jagged1 expression were inhibited by siRNA interference. The growth rate of PC3 cells was measured by MTT. Notch1 expression was inhibited by siRNA interference and promoted by transfection of Notch1 cDNA. The changes of Notch1 and Jagged1 protein and mRNA levels were measured by Western blot and Real-time RCR. Results The growth of PC3 cells decreased after inhibiting Notch1 and Jagged1 expression. Jagged1 protein level decreased after inhibiting Notch1 expression and increased after over-expressing Notch1. Moreover, the change of Jagged1 protein level was discordant with the situation of mRNA. Conclusion In PC3 cells, Notch1 and Jagged1 are important to cell growth. Notch1 may regulate Jagged1 expression.

Objective To observe the activation of astrocytes,microglia and expression of proinflammatory cytokines in the periaqueductal gray(PAG) by Complete Freunds Adjuvant(CFA)-induced inflammatory pain. Methods Heat hyperalgesia and mechanical allodynia were observed and the expressions of mRNA,protein of glial markers,and proinflammatory cytokines in the PAG were examined following intraplantar administration CFA in right hindpaw of the rat by behavioral testing,reverse transcription polymerase chain reaction(RT-PCR), Western blotting,and immunohistochemistry. Results CFA injection induced chronic thermal hyperalgesia and mechanical allodynia.After injection,the thermal hyperalgesia was recovered on Day 14,but the mechanical allodynia lasted more than 21 days.Microglial marker(Cluster of differentiation 14,CD14) and proinflammatory cytokines(Interleukinin-1?,tumor necrosis factor-?) showed a significant increase in their expression during all phases(acute,subacute and chronic) of inflammation.GFAP was observed only in PAG at subacute and chronic phases of inflammation.Conclusion The activation of microglia and astrocytes may be involved in the initiation and maintenance of inflammatory pain.Enhanced cytokines expression might play a role in eliciting behavioral hypersensitivity.
