Purpose To investigate the expression and significance of androgen receptor (AR) in breast carcinoma with different ER and PR status.Methods Immunohistochemical method was used to detect AR, ER and PR expression in 173 cases of breast carcinoma, and all the cases were grouped according to: (1) AR status: AR~- positive subgroup and AR~- negative subgroup, (2) ER status: En subgroup (negative for both ER and PR), Ep subgroup (positive for ER and/or PR), (3)AR, ER and PR status: En-AR~+ subgroup (AR~- positive cases of En subgroup), En-AR~- subgroup (AR~-negative cases of En subgroup), Ep-AR~+ subgroup (AR~- positive cases of Ep subgroup), and Ep-AR~- subgroup (AR~-negative cases of Ep subgroup).En-AR~- subgroup also was called negativE-for-all subgroup, and the rest three subgroups were called partly-or-completely positive subgroup (positive for at least one of the three markers), and then, the groups were compared with clinicopathological features.Results The positive rate of AR was 62.8% (54/86) in Ep subgroup and 37.9%(33/87) in En subgroup, and there was significant difference between them (P=0.001).Compared to AR~-negative subgroup, AR~-positive subgroup had smaller tumor size, less mitosis count and lower grade(P<0.05).Compared to the other three subgroups, En-AR~- subgroup had more mitosis count and higher grade (P<0.01).In En subgroup,AR~- positive cases had less mitosis count and lower grade (P<0.05), and in Ep subgroup,AR~- positive cases had higher stage(P=0.000), but no significant difference were found among partly or completely positive subgroups.Conclusions The expression of AR may play a different role in breast carcinoma with different ER and PR status, because it indicates good prognosis in negative for both ER and PR subgroup, but bad in ER and/or PR positive subgroup. When choosing a personalized therapy, all the combinations of hormone receptor status should be considered for the patients.

Purpose To investigate the relationship between molecular phenotype of ductal carcinoma in situ ( DCIS) and that of inva-sive ductal carcinoma ( IDC) of the breast. Methods Immunohistochemical method was used to detect ER, PR, HER-2 and CK5 ex-pression in 165 cases of breast cancer, with DCIS and IDC existed in every one of the samples. Results In the 165 cases of breast cancer, the ER, PR, HER-2 and CK5 expression of IDC was positively correlated with that of DCIS, respectively. To evaluate IDC phenotype, the number of basal phenotype was 18 (10. 9%), HER-2-overexpression 20 (12. 1%), luminal A 102 (61. 8%), lumin-al B 20 (12. 1%), null phenotype 6 (3. 6%);to evaluate DCIS phenotype, the number of basal phenotype was 19 (11. 5%), HER-2-overexpression 20 (12. 1%), luminal A 104 (63%), luminal B 17 (10. 3%), null phenotype 5 (3%). 157 cases (95. 2%) of IDC had the same phenotype with DICS, but the rest 8 cases (4. 8%) not, three cases of luminal A DCIS transformed into one HER-2-overexpression and two null phenotype IDC, three of HER-2-overexpression DCIS transformed into luminal B IDC, one null pheno-type DCIS transformed into one luminal A IDC, and one basal phenotype DCIS transformed to HER-2-overexpression IDC. Conclusion Most of IDC have the same phenotype with DCIS, but there exist small part of DCIS which could transform into other phenotype IDC.

OBJECTIVETo apply needle-knife to treat lumber disc herniation (LDH) and surface electromyography were used to analyze biomechanical characteristic of patient's lumber muscle to make a comprehensive evaluation on its efficacy.

METHODSThirty patients who met the inclusive criteria were selected and treated with needle-knife, once a week for 2 weeks. Visual analogue scale (VAS), ASLR and JOA score before and after treatment were observed. Surface electromyography was applied to test the surface electromyography signals. AEMG, MFs and MPF were calculated before and after the treatment.

RESULTSAfter treatment, VAS was significantly reduced, ASLR, JOA, AEMG and MPF were obviously increased, and the absolute value of MFs was lowed (all P < 0.01).

CONCLUSIONThe needle-knife could significantly relieve lumbar muscle strength, muscle tone and muscle fatigue, improve in the imbalance of lumbar extensor muscle group, leading to the recovery of biomechanical characteristic, and the clinical efficacy is superior.

Etiology of adolescent idiopathic scoliosis (MS),a complicated three-dimensional spinal deformity with early-onset,receives continuous attention but remains unclear.To gain an insight into AIS pathogenesis,this review searched PubMed database up to June 2019,using key words or medical subject headings terms including "adolescent idiopathic scoliosis," "scoliosis," "pathogenesis,etiology," "generics,mesenchymal stem cells," and their combinations,summarized existing literatures and categorized the theories or hypothesis into nine aspects.These aspects include bone marrow mesenchymal stem cell studies,genetic studies,tissue analysis,spine biomechanics measurements,neurologic analysis,hormone studies,biochemical analysis,environmental factor analysis,and lifestyle explorations.These categories could be a guidance for further etiology or treatment researches to gain inspiration.

Objective:To investigate the effects of estradiol on ~(60)Co?-ray induced apoptosis of bone marrow hematopoietic cells of mice,and to discuss the related anti-irradiation mechanism.Methods:KM mice were randomly divided into 3 groups(15 mice/each group):control group(without radiation),pure radiation group and estradiol+radiation group(ER group).The pure radiation group was irradiated by 4.0 Gy?-ray at a dose rate of 1.15Gy/min;the ER group was administered with 0.1 mg estradiol(IM)at 10 days before 4.0 Gy?-ray radiation;and the control group received no special treatment.The apoptotic DNA segments of bone marrow hematopoietic cells were analyzed by DNA agarose gel electrophoresis;flow cytometry was used to examine the apoptosis rate of cells and expression of Fas and Bcl-2 at 4 h,8 h,and 12 h after irradiation.Results:Eight hours after radiation,the apoptotic DNA segments were obviously increased and apoptotic DNA ladder appeared,which was not seen in the other 2 groups.The apoptosis rate of bone marrow hematopoietic cells in ER group was significantly lower than that in the pure radiation group at 4,8,and 12 h after irradiation(P

This paper reports the establishment of a method for rapid identification 15 effective components of anti common cold medicine (paracetamol, aminophenazone, pseudoephedrine hydrochloride, methylephedrine hydrochloride, caffeine, amantadine hydrochloride, phenazone, guaifenesin, chlorphenamine maleate, dextromethorphen hydrobromide, diphenhydramine hydrochloride, promethazine hydrochloride, propyphenazone, benorilate and diclofenac sodium) with MRM by LC-MS/MS. The samples were extracted by methanol and were separated from a Altantis T3 column within 15 min with a gradient of acetonitrile-ammonium acetate (containing 0.25% glacial acetic acid), a tandem quadrupole mass spectrometer equipped with electrospray ionization source (ESI) was used in positive ion mode, and multiple reaction monitoring (MRM) was performed for qualitative analysis of these compounds. The minimum detectable quantity were 0.33-2.5 microg x kg(-1) of the 15 compounds. The method is simple, accurate and with good reproducibility for rapid identification many components in the same chromatographic condition, and provides a reference for qualitative analysis illegally added chemicals in anti common cold medicine.

OBJECTIVE: To compare peripheral T lymphocyte apoptosis of chronic bronchitis during an acute episode with that during a stable period. METHODS: Seventeen Chronic Btonchitis patients who presented to the ER with an acute episode were compared with 10 stable Chronic Bronchitis patients seen in the out-patient clinic. Peripheral venous blood was obtained from each patient and T lymphocytes were separated by fluorescent monoclonal antibodies. CD3, CD95 and CD25 were measured by flow cytometry. RESULTS: In the acute episode patients, the total quantity of T lymphocytes with CD3 was (42.63 +/-16.37) and with CD95 (14.15 +/-11.06). In the stable group T lymphocyte CD3 was (64.22 +/-23.90) and CD95 (34.88 +/-8.92) (t=-4.238, P <0.001; t=-8.796, P <0.001). The total quantity of Lymphocyte CD25 did not differ significantly between the two groups (P > 0.05). Total quantity of active T lymphocytes with CD3/CD25 was lower in the acute episode group (6.26 +/-3.94) compared to the stable group (10.52 +/-3143) (t=-1.068, P <0.05). CONCLUSION: T lymphocyte apoptosis increased in Chronic Bronchitis patients who presented with an acute episode. They also experienced a significant disturbance in immune function.
