Objective To investigate the relationship between androgen receptor CAG-gene polymorphism and androgen in male with salt sensitive hypertension.Methods Through the oral saline loading test and furosemide volume method male hypertension group were divided into salt-sensitive (SS group) and salt-insensitive (SR group).The samples from 161 males were selected in the study,including salt sensitive hypertension patients (SS group,61/161),salt-insensitive hypertension patients (SR group,40/161) and age-matched healthy samples (control group,60/161).All samples were sequenced with an analysis method (CAG) n repeated polymorphism,and determinated of total testosterone (TT) and free testosterone (FT) level in serum by electrochemiluminescence immunoassay.Results The number of CAG repeats was 14～34,average 22.4± 2.7.The CAG repeats of SS,SR and control group were 23.5±3.75,22.3±3.17 and 21.8±2.95,respectively.There were significant differences among the three groups (t=2.627～ 3.257,all P＜0.05).The level of TT and FT in SS and SR group were decreased compared with that of control group.At the same time,the level of SS group was lower,and there were significant differences among the three groups (t=2.524～ 3.826,all P＜0.05).Conclusion The androgen receptor gene repeat length and androgen levels are associated with male hypertension,especially salt-sensitive hypertension.Long (CAG) n repeat polymorphism maybe a genetic factor in the pathogenesis of hypertension.Plasma androgen levels may be used as a predictor of male salt sensitive hypertension.

OBJECTIVETo compare the differences in the therapeutic effect on irritable bowel syndrome (IBS) between acupuncture at Tianshu (ST 25) and Dachangshu (BL 25) and western medication with Trimebutine Maleate.

METHODSForty cases were divided randomly into an acupuncture group and a western medication group, 20 cases in each one. In acupuncture group, acupuncture was applied to Tianshu (ST 25) and Dachangshu (BL 25). Ziwu Daojiu needling technique was adopted, once daily. In western medication group, Trimebutine Maleate capsule was administered, 2 capsules in each time, 3 times per day. The assessment on the therapeutic effect was performed in 4 weeks of treatment in two groups.

RESULTSAs compared with those before treatment, the time of abdominal pain, the frequency of abdominal pain, the morbidity of abnormal stool appearance, the morbidity of defecation abnormality, the morbidity of mucus stool and the score of bloating or abdominal pain on bowel movement were all reduced after treatment in two groups (all P < 0.01). The results in acupuncture group were much more significant than those in western medication group (the total score: 16.70 +/- 2.40 vs 15.70 +/- 3.01, P < 0.01). The total effective rate in acupuncture group was 95.0% (19/20), which was superior to that of 70.0% (14/20) in western medication group (P < 0.05).

CONCLUSIONAcupuncture at Tianshu (ST 25) and Dachangshu (BL 25) may remarkably relieve the clinical symptoms of IBS and its efficacy is superior to that of oral medication with Trimebutine Maleate.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

In this article, we summarize clinical features and management of 3 cases with pathology confirmed granulomatous hypophysitis, to improve knowledge and provide treatment guidance in this regards. Patients presented with headache, blurred vision and central diabetes insipidus, respectively. The imaging manifestations were sellar area or pituitary stalk occupying lesions, and the nature was undetermined. The symptoms were not completely relieved after subtotal resection or biopsy. The symptoms could be controlled by high dose glucocorticoid, but relapsed after reduction. Two patients were treated with glucocorticoid combined with azathioprine. One case had no recurrence after withdrawal of the drug and 1 patient was still in treatment. Therefore, for the patients whose symptoms are still not relieved after operation and recurred after glucocorticoid reduction, the scheme of high-dose glucocorticoid combined with immunosuppressant azathioprine can be considered, which may achieve satisfactory curative effect and prognosis.

Objective To analyze risk factors for delayed postpolypectomy bleeding (DPPB) of colorectal polyps. Methods We reviewed 1 098 patients (2 169 polyps) who accepted endoscopic polypectomy from July 2014 to July 2017. Evaluate the risk factors for DPPB. Results DPPB occurred in 18 (1.6%) cases. Univariate analysis revealed that history of hypertension (P = 0.007), polyp size ≥10 mm (P = 0.009), right hemicolon location (P = 0.015) and adenomatous polyp (P = 0.045) were risk factors for DPPB. Multivariate logistic regression analysis revealed that history of hypertension (P = 0.002, O(R) = 4.654, 95%CI: 1.755 ~ 12.343), polyp size ≥10 mm (P = 0.009, O(R) = 3.637, 95%CI: 1.390 ~ 9.517), location in the right hemicolon (P = 0.016, O(R) = 3.656, 95%CI:1.273 ~ 10.504) were independent risk factors for DPPB. Conclusion Patients with history of hypertension, polyp size ≥10 mm, polyp location in the right hemicolon are prone to DPPB. We should take effective measure to prevent DPPB.

Objective:Iron accumulation is related to the occurrence of postmenopausal osteoporosis. Meanwhile, autophagy abnormality of bone marrow hematopoietic cells is observed in hip osteoporotic fracture. This study is performed to investigate correlation between iron accumulation induced bone loss and hematopoietic autophagy dysfunction to explore the new risk factor of osteoporosis.Methods:Male iron accumulation mice model was established by intraperitoneally injecting ferric ammonium citrate. Serum ferritin and osteogenic indicator P1NP were tested by ELISA. Bone mineral density was measured by micro-CT. Femur and tibia bone marrows were collected for hematopoietic stem and progenitor cells proportion and cell apoptosis analysis. Autolysosome formation was measured by image flow cytometry. We used conditional mouse model Atg7 flox/flox; Vav-Cre(Atg7 -/-) in which Atg7 had been genetically deleted in the hematopoietic system. Bone marrow hematopoietic stem and progenitor cells were collected for RNA sequence. micro-CT scan was conducted for Atg7 -/- femur. Results:Ferritin level of iron accumulation mice was significantly higher than control group( P<0.05). Iron accumulation inhibited P1NP and induced decreased bone mineral density( P<0.05). Iron accumulation bone marrow displayed enhanced hematopoietic stem and progenitor cells proportion( P<0.05), with more cell apoptosis( P<0.05). Hematopoietic autophagy was deteriorated in iron accumulation bone marrow. Transcriptomic profiling showed up-regulation of iron activity in Atg7 -/- mice, with increased iron homeostasis and iron membrane transporter genes, including Lcn2, Tfr2, Slc40a1(Fpn1), Steap3, and Cpox. micro-CT revealed severe bone loss and decreased bone mineral density in Atg7 -/- mice( P<0.05). Conclusion:Iron accumulation induced bone loss is related to inhibition of hematopoietic cells. Hematopoietic autophagy dysfunction is associated with bone loss.
