2.HETEROGENEITY OF SERUM HUMAN GROWTH HORMONE IN ACROMEGALY BEFORE AND AFTER TREATMENT
Chinese Journal of Endocrinology and Metabolism 1985;0(01):-
The heterogeneity of serum human growth hormone (hGH) in 6 normal subjects and 17 acromegalic patients before and after treatment has been studied. The results showed that "little hGH" was 34.4?10.2% and 69.8 ?13.9% of total hGH in normal subjects and in acro-megalies respectively, and that the percentage of little hGH in acromegalies increased significantly (p
3.Could Ex-PRESS miniature implantation replace the trabeculectomy in China?
Chinese Journal of Experimental Ophthalmology 2015;33(3):193-195
Ex-PRESS miniature implantation is a new alternative of anti-glaucoma surgeries due to its advantages,such as simpler operation,similar efficacy to trabeculectomy and less complications.Could Ex-PRESS miniature implantation replace the trabeculectomy? Studies showed that Ex-PRESS implantation has more significant advantages to those patients with high risk for trabeculectomy but dose not has dominant benefits to those prone to failure of trabeculectomy from bleb scarring.The Ex-PRESS implantation requires a relative wide angle so as to have enough space to avoid the device accessing to corneal endothelium,iris or lens.So it is unsuitable for angle-closure glaucoma with higher incidence in China.In addition,the cost-effect for Ex-PRESS implantation should also be fully considered when this method could be put into practice in the near future in China.Ex-PRESS implantation seems to be unable to displace trabeculectomy.The merits and demerits for Chinese patients still need to verify by Chinese own evidence-based studies.
4.Observation of development of ovarian follicle and blood flow in endometrium by transvaginal color Doppler flow imaging
Chinese Journal of Ultrasonography 2001;10(2):92-94
Objective To observe the relationship among the degree of maturation of development of ovarian follicle and endometrial thickness and resistance index of uterine helicine arteries.Methods Fifty six cases of normal menstrual cycle were studied by transvaginal color Doppler flow imaging.Results Diameter of ovarian follicle increased and moved to the surface of ovary before ovulation,endometrium thickened and resistance index of uterine helicine arteries decreased.Conclusions Observation of the development of ovarian follicle by transvaginal color Doppler flow imaging is helpful to improve regnancy rate.
5.Safety and clinical application of induced pluripotent stem cells
Chinese Journal of Tissue Engineering Research 2013;(27):5087-5093
BACKGROUND: Induced pluripotent stem cells are obtained from somatic cells by reprogramming method. The safety of induced pluripotent stem cells has attracted much attention because of their huge and potential value in clinical application. OBJECTIVE: To review the current studies addressing the safety and clinical application of induced pluripotent stem cells. METHODS: The PubMed database between 2006 and 2012 was retrieved by the first author to search the correlative documents concerning the safety and clinical application of induced pluripotent stem cells. Total y 203 papers were primarily gotten. Final y, 47 papers were included. RESULTS AND CONCLUSION: At present, the main methods to enhance the safety of induced pluripotent stem cells include avoiding usage of c-Myc gene, another mediate way replacing the retrovirus, direct leading of reprogramming factor protein, safer donor cells, micromolecule compound and other in-transgenosis ways. Induced pluripotent stem cells have extensive clinic treatment prospects, and can be used for the build of disease-specific induced pluripotent stem cells line.

Two hundred and thirty two patients with essential hypertension were divided into intervention and control groups (116 in each) ,by the end of study period (from January 2005 to January 2006) 106 patients in intervention group (91.4%) and 102 in control group (87.9%) completed observation.The main findings were as follows: the blood pressure control rate in intervention group was higher than that in controls (X2=23.92,P <0.01) ;the family adaptability(X2 =31.12,P <0.01),family caring(X2=37.90 ,P<0.01),family communication (X2= 17.91,P<0.01) and family function(X2 = 8.26,P<0.01)in intervention group were better improved than those in control group.The results suggest that family can be effective resources for improvement of patients with essential hypertension.

Optical coherence tomography (OCT) can depict mild papilledema and slight changes in the internal segment and external segment; measure thickness of the retinal nerve fiber layer,retinal thickness and macular volume; detect missing axons and damage to the macular ganglion cell complex.Thus,OCT has important application values and widespread prospects in diagnosis and differential diagnosis of glaucoma and non-glaucoma optic neuropathy,optic nerve diseases and macular diseases,outer and inner retinopathy as well as evaluation of curative effects,follow-up observation,prognosis and mechanisms in neuroophthalmological diseases.Neuro-ophthalmologists should pay more attention to the exploration and application of OCT in the field of neuro-ophthalmology.

Objective To observe and measure the Doppler sonographic features of benign and malignant ovarian neoplasms,which included morphology and hemodynamics of tumor angiogenesis,and to select the most significant features. Methods Ninety-five patients with one hundred and five ovarian tumors were examined preoperatively by power Doppler sonography to observe the morphology of tumor angiogenesis. The hemodynamic features of tumor angiogenesis referred for pulsed Doppler sonography evaluation were measured,which included peak systolic velocity(V PS ),end diastolic velocity(V ED ),mean flow velocity(V M),pulsatility index(PI),resistance index(RI) and diastolic notch. To assess the variables jointly,stepwise regression analysis was used to identify the group of features that allowed the best prediction of benignity versus malignancy. Results All Doppler features significantly associated with malignancy .The ROC curve of RI revealed that the cutoff of RI( 0.51 ) with the highest accuracy had a sensitivity of 98.0 % and specificity of 96.2 %.Conclusions RI was most significantly associated with malignancy. The combination of RI and gray-scale sonography can maximize the ability to discriminate between benign and malignant ovarian tumors.
