Objective To investigate the hysteromyoma treated with the gonadotropin releasing hormone agonist(GnRH-a)and the impact on immunologic function.Methods 130 cases selected from the patients with hysteromyoma enrolled from January 2016 to December 2016 in hospital have been randomly divided into two groups.The control group has been treated with mifepristone while the study group GnRH-a.Results The sizes of uterus and myoma of both groups have no significant difference before treatment.After treatment, both of them are significantly improved, and those of the study group is significantly smaller than that of the control group(P<0.05).The levels of serum sex hormone and immunologic function of both groups have no significant difference before treatment.They are both improved after treatment, and the study group is significantly better than the control group(P<0.05).Conclusion Applying GnRH-a therapy to the patients with uterine myoma benefits for improving the therapeutic effect, which can improve the serum sex hormone levels and immunologic function.

BACKGROUND:Hydrophilic acrylic materials with good biocompatibility have been widely used in clinic. However, there are some problems about the biocompatibility and safety of hydrophilic acrylic intraocular lens after long-term clinical application. OBJECTIVE:To discuss the biocompatibility and stability issues and corresponding processing methods after hydrophilic acrylic intraocular lens implantation. METHODS:A computer-based search of Wanfang and PubMed database was performed for articles related to clinical application of hydrophilic acrylic intraocular lens published from 2005 to 2014. The keywords were “hydrophilic acrylic,intraocular lens” in Chinese and English, respectively. A total of 618 articles were initialy retrieved, and finaly 35 articles were included in result analysis. RESULTS AND CONCLUSION:As the hydrophilic acrylic intraocular lens is foldable, a smal incision is required for implantation and the operation is simple that cause less damage to the patients. In addition, the hydrophilic acrylic intraocular lens has poor bacterial and inflammatory cel adhesion, which leads to a low probability of infective endophthalmitis after implantation. But there is a high incidence of posterior capsule opacification as wel as some refractive errors and visual quality problems after implantation. Taken together, to solve these problems depends on the continuous improvements and updates of intraocular lens materials and designs.

The pollen morphology of 3 species of the Echinacea Moench. from China and other coun-tries was examined under LM and SEM. 3 species were palynologically reported here for the first time. Theresults showed that the pollen morphology of the Echinacea species mentioned above was basically consis-tent, but some differences in pollen size, aperture and exine sculpture were found.

Objective To discuss the clinical application of ultrasound-guided preoperative guide-wire localization in diagnosing tiny breast lesions. Methods A total of 56 patients with impalpable tiny breast lesions were enrolled in this study. Preoperative guide-wire localization of the lesion was performed under high-frequency ultrasound guidance, which was followed by tracking resection of the lesion. The clinical data were retrospectively analyzed. Results Successful localization and complete resection of the lesion was accomplished in all 56 patients. The lesions included invasive ductal carcinoma (n=11), intraductal carcinoma (n=5), ductal carcinoma in situ (n=2), mucinous carcinoma (n=2), fibroadenoma (n=24), atypical hyperplasia (n=6), intraductal papilloma (n=4) and plasma-cell mastitis (n=2). Conclusion Ultrasound-guided preoperative guide-wire localization is a safe and reliable technique for the diagnosis of impalpable tiny breast lesions. It can precisely localize the lesion, which is very helpful for making a complete resection of the lesion and avoiding unnecessary breast injury. Therefore, this technique should be recommended in clinical practice.

Objective To explore the diagnostic value of ultrasonic elastography and fine flow imaging in differential diagnosis of cervical lymph nodes.Methods Totally 87 lymph nodes were examined with ultrasonic elastography,fine flow and conventional ultrasonography.The results were confirmed with postoperative pathology or fine-needle biopsy as well as follow-up.Using consistency check of Kappa and ROC curve to analyse the accuracy of three types of ultrasonic examination.Results Taking the results of postoperative pathology or fine-needle biopsy as well as follow-up as golden standards,the Kappa value of conventional ultrasonography was poor (Kappa =0.153,P =0.078),fine flow was moderate (Kappa =0.526,P ＜0.01) and ultrasonic elastography was better (Kappa =0.741,P ＜0.01).The area under ROC of ultrasonic elastography,fine flow and conventional ultrasonography was 0.899 (P ＜0.01),0.787 (P ＜0.01) and 0.568 (P =0.241),respectively.Conclusions Ultrasonic elastography is more valuable to differentiate malignant from benign lymph nodes.

Objective To evaluate sound velocity tissue quantification ( SVQ ) for the quantitative assessment of liver fibrosis stage in chronic hepatitis B ,and to evaluate the correlation between diagnostic performance of sound velocity tissue quantification and blood parameters . Methods From the May of 2013 to May of 2014 ,collect ninety‐nine patients with chronic hepatitis B who was diagnosed by clinic and / or liver biopsy as experiment group ,and thirty healthy volunteers as control group at the same time . The experiment group and control group were evaluated with to measurement the zone speed index ( ZSI) ,and blood cell count . The AST/PLT ratio index ( APRI) was calculated according the following formula , APRI=AST(ULN)/PLT(109/L) . The liver biopsy was performed in the same day with SVQ and all blood parameters .ZSI and APRI were compared by correlation with liver fibrosis stage in chronic hepatitis B . Referring to the histologic fibrosis stage on liver biopsy ,all the ZSI and the APRI value were assessed by using ROC curve analysis .
