AIM: To investigate clinical effects of local resection of eyelid tumors and pathological examination or frozen section examination as well as the stage I recovery.
METHODS: For all 92 cases 92 eyes of eyelid tumor patients who underwent local resection, reconstruction in stage Ⅰ and routine pathological examination ( 37 cases of suspected malignant tumors using frozen section examination. If it was malignant, excision by Moths surgery) . Using free palate mucosa autograft in stage I or reconstruction by Hughes surgery combined with eye flaps repaired eyelid defects.
RESULTS: The postoperative pathological diagnosis:52 cases were benign tumors, and 40 cases malignant tumors. All cases of eye flaps and hard palate mucosa grafts were survived. Followed up for more than 6mo, no tumor were recurred. The appearance and function of eyelid were satisfactory.
CONCLUSION: In this group of cases, nearly half of eyelid tumors are malignant tumors. It should be treated and operated as early as possible. For suspected malignant tumors, we use frozen section examination to confirm its properties in order to excision cleanly in stageⅠ, reducing the recurrence and metastasis. According to the eyelid defect after resection, we could do repair operation in stage Ⅰ. The inner larger defect is repaired by using hard palate mucosa transplantation or Hughes surgery. The outer layer of the eyelid defect is repaired by using eye flap glide, the free flap, the kite flap, the simple suture, etc. It should be careful when using the hard palate mucosa transplantation in the upper eyelid defect.

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.

BACKGROUND: Cardiac reserve indicators obtained under quiescent condition are used as evaluating index for cardiac reserve functions. However, most important aspect of cardiac dysfunction in heart failure is not the depressed cardiac performance noted at basal resting states, but rather the loss of cardiac reserve. OBJECTIVE: To develop a data processing and information management system for detecting cardiac reserve indicator with the widely used B mode ultrasound instrument in the ultrasonography field, and to provide guidance for B mode ultrasound instrument perfection. METHODS: General B mode ultrasound instrument as peripherals was connected with the pc by image acquisition card; ultrasound heart image diagnosis and management system including professional heart image acquisition and process and perfect data bank was develop. RESULTS AND CONCLUSION: An efficient and flexible mini picture archiving and communication system system was achieved, which realized image enhancement, geometric parameter measuring, convenient diagnosis report output, archive management and print function. Results demonstrated that with the powerful data process ability of PC, the system could improve the performance of the traditional ultrasound instrument in detecting cardiac reserve, which provide a powerful support for the further study.

Referring to the rapid developed life science and the higher requirements for the approval of innovative Chinese drugs in recent years, this paper described systematically the discovery, research and development (R&D) approaches for the innovative Chinese drugs under the new situation from the following five aspects, i. e., active components discovered from TCMs, the discovery of effective fractions of TCMs and their formulae, the R&D of TCM innovative drugs based on famous classic prescriptions and famous Chinese patent drugs, and the transformation of clinical effective prescriptions, on the basis of analysing the advantages of innovative drugs derived from natural products based on TCM theories and the problems existed in current R&D of new TCM drugs. Moreover, five suggestions are also given for the rapid development of TCM innovative drugs in China. All these will provide reference for the R&D of TCM innovative drugs.

Objective:To study the clinical features, experiences of diagnosis and treatment, and treatment process of ovarian nonspecific steroid cell tumor. Methods:The clinical materials of one case of ovarian nonspecific steroid cell tumor were retrospectively analyzed,and the related literaturels were reviewed. Results:The patient displayed amenorrhea and masculine characteristics.Preoperative ultrasonography demonstrated the solid tumor of 53 mm ×39 mm on the right ovary,consideration for the right side of ovarian malignant tumor,and laparotomy was performed.The pathologic results showed that the tumor cells were arranged in nests,and the cytoplasm was bright or eosinophilic, and the nucleus were round or oval with nucleolus.The immunohistochemical staining results revealed that calretinin,vimentin and inhibin were positive in the tumor cells.The patient was diagnosed with ovarian nonspecific steroid cell tumor.The postoperative follow-up of 3 months was performed,and there was no recurrence.Conclusion:The diagnosis of ovarian nonspecific steroid cell tumor should be combined with the clinical manifestation and pathologic results,and operion is the main treatment method.

AIM: To analyze the effect of human amniotic homogenate extract on corneal neovascularization after corneal alkali burn in the process of pigment epithelium derived factor (PEDF) and vascular endothelial growth factor (VEGF) expression and the effect of corneal neovascularization.METHODS: Totally 32 patients with corneal alkali burn were selected from June 2015 to June 2016 in Foshan,and were randomly divided into Group A and Group B,with a total of 37 eyes.Group A of 17 cases,with a total of 19 eyes,were treated with 40mg/L human amniotic homogenate extract;Group B (n=15),and 18 eyes,treated with 3g/L prednisolone eye drops.In the treatment of 1,4,7,14,21 and 28d at different time points,we observed the growth of corneal neovascularization,and detected the expression of PEDF and VEGF during angiogenesis.RESULTS: Group A of patients in the use of human amniotic homogenate extract after the treatment,the expression level of PEDF was significantly higher than that in Group B(P=0.001),after 28d treatment,the expression level of PEDF reached 0.721±0.314.While patients in Group B the expression level of PEDF was only 0.538±0.253.Two groups had significant difference between the expression level of PEDF (P<0.05).The expression level of VEGF in Group A was lower than in Group B at different time points in the test.After the treatment of 28d patients in the Group A,the expression level of VEGF was 0.152±0.020,in Group B the expression level of VEGF was0.302±0.031.Two groups of patients with VEGF expression level between the differences were statistically significant (P<0.05).The patients number in Group A with corneal neovascularization was significantly lower than that in Group B,the difference was statistically significant (P<0.05).CONCLUSION: Human amniotic homogenate extract can increase the expression of PEDF in corneal neovascularization after corneal alkali burn,inhibit the expression of VEGF and the proliferation of corneal neovascularization.
