Objective To investigate the relationship of carotid artery atherosclerosis and the plasma level of RAS in hypertension patients.Methods We retrospectively analyzed clinic data of essential hypertension patients treated in the department of cardiology department between Jan 2015 and Mar 2016.Results Carotid artery plaque was associated with age,blood sugar,total cholesterol,low density lipoprotein-cholesterol,and uric acid.The prevalence of carotid artery atherosclerosis increased with increasing level of plasma erect and decubitus position angiotensin Ⅱ and erect position renin (P ＜ 0.05).Logistic regression analysis indicted that age,decubitus position angiotensin Ⅱ,TC,UA was positively associated with carotid atherosclerosis,HDL-C was negatively correlated with carotid atherosclerosis(P ＜ 0.05).Conclusion Carotid artery atherosclerosis is independently associated with Ang Ⅱ.

To knock out β-lactoglobulin (BLG) gene and insert human lactoferrin (hLF) coding sequence at BLG locus of goat, the transcription activator-like effector nucleases (TALEN) mediated recombination was used to edit the BLG gene of goat fetal fibroblast, then as donor cells for somatic cell nuclear transfer. We designed a pair of specific plasmid TALEN-3-L/R for goat BLG exon III recognition sites, and BLC14-TK vector containing a negative selection gene HSV-TK, was used for the knock in of hLF gene. TALENs plasmids were transfected into the goat fetal fibroblast cells, and the cells were screened three days by 2 μg/mL puromycin. DNA cleavage activities of cells were verified by PCR amplification and DNA production sequencing. Then, targeting vector BLC14-TK and plasmids TALEN-3-L/R were co-transfected into goat fetal fibroblasts, both 700 μg/mL G418 and 2 μg/mL GCV were simultaneously used to screen G418-resistant cells. Detections of integration and recombination were implemented to obtain cells with hLF gene site-specific integration. We chose targeting cells as donor cells for somatic cell nuclear transfer. The mutagenicity of TALEN-3-L/R was between 25% and 30%. A total of 335 reconstructed embryos with 6 BLG-/hLF+ targeting cell lines were transferred into 16 recipient goats. There were 9 pregnancies confirmed by ultrasound on day 30 to 35 (pregnancy rate of 39.1%), and one of 50-day-old fetus with BLG-/hLF+ was achieved. These results provide the basis for hLF gene knock-in at BLG locus of goat and cultivating transgenic goat of low allergens and rich hLF in the milk.

The clinical data of 1 case of oral hydrochloric acid poisoning successfully treated was retrospectively analyzed to provide reference for diagnosis and treatment of similar clinical cases.

Objective: To investigate the etiology, clinical features, treatment and outcome of nephrotic syndrome associated with chronic mercury poisoning. Methods: From June 2013 to April 2018, Beijing Chaoyang Hospital, Capital Medical University received 33 patients with chronic mercury-neutral nephrotic syndrome. The clinical manifestations, laboratory tests, treatment methods, and outcomes were analyzed. Results: Among the 33 patients, 27 patients had mercury exposure due to daily-life contact and the other 6 patients were caused by iatrogenic mercury. The symptom was characterized by typical nephrotic syndrome such as lower extremity edema and proteinuria at first onset. The treatment was based on mercury-removing treatment, 19 cases were treated with mercury removal alone, 16 cases were completely relieved; 10 cases were treated with mercury removal and glucocorticoids, all of which were completely relieved; 4 cases were treated with mercury removal, glucocorticoids and immunosuppressive agents, all complete remission; clinical complete remission rate is about 90.9% (30 cases in total) . Urinary mercury levels decreased the fastest between the first and second courses of mercury treatment, but the total amount of urine protein increased. As the amount of urinary mercury excreted increased, the total amount of urine protein decreased gradually (Z=2.86, P<0.01) . Conclusion The clinical features of chronic mercury-induced nephrotic syndrome are non-specific, easy to be misdiagnosed and missed. The treatment is mainly treated with mercury removal treatment. The prognosis is good. In severe cases, glucocorticoid therapy can be supplemented.

OBJECTIVE: To compare the diagnostic value of high-k V X-ray chest photography and chest high-resolution computed tomography( HRCT) in the diagnosis of pulmonary thesaurosis induced by dust of iron and its compounds(hereinafter called the iron pulmonary thesaurosis). METHODS: A total of 80 workers exposed to iron oxide dust in a magnetic material factory were collected as the study subjects by convenience sampling method,and they were examined with high-k V X-ray chest photography and HRCT. Differences between the two methods in the diagnosis of iron pulmonary thesaurosis were compared. RESULTS: Of the 80 workers,only 5 of them(6. 2%) showed no abnormal changes in chest HRCT,others showed varying degrees of diffuse distribution of air-cavity nodules and ground-glass lesions. High-k V X-ray chest photography and chest HRCT diagnosis of iron pulmonary thesaurosis accounted for 8. 8%( 7/80) and 37. 5%(30/80) with extreme mild degree,and 21. 3%(17/80) and 26. 3%(21/80) with mild degree respectively. The diagnostic rates for iron pulmonary thesaurosis were 30. 0%( 24/80) and 63. 8%( 51/80),respectively. There was consistency between the two methods for the diagnosis of iron pneumoconiosis( Kappa = 0. 411,P < 0. 01). The chest HRCT has a higher diagnostic classification and diagnosis rate compared with the high-k V X-ray chest photography( P <0. 01). CONCLUSION:s The chest HRCT has a higher diagnostic grade and higher diagnostic rate for lung siderosis compared with the high-k V X-ray chest photography,which is helpful for the early diagnosis of the disease.
