AIM: To observe the effect of curcumin on the retinal structure and the expressions of interleukin-23 (IL-23) and interleukin-17(IL-17) in the rat retina after retinal ischemia-reperfusion injury (RIRI).METHODS:A total of 60 male Sprague-Dawley(SD) rats were randomly divided into normal control group(NCG),model group(MG),low-dose curcumin group (LDCG) and high-dose curcumin group (HDCG) (n=15 per group).RIRI was generated by anterior chamber perfusion of normal saline to the right eye.Rats in LDCG and HDCG received an intraperitoneal injection of 20mg/kg/d and 100mg/kg/d curcumin respectively,at 30min before RIRI and once daily after RIRI.Retinal structure and inflammation were evaluated after hematoxylin and eosin-stained (HE) staining.Western-blot and enzyme-linked immunosorbent assay (ELISA) were used to measure the level of IL-23 and IL-17 expressions after RIRI.RESULTS: The retinal structure of NCG was normal.Retinal edema,empty spaces or loosely packed cells and inflammatory cell infiltration were observed in MG and LDCG groups,whereas the morphological changes in HDCG group were improved as compared to MG and LDCG groups.Western-blot assay and ELISA showed that IL-23 and IL-17 expressions increased significantly after RIRI (vs NCG,P<0.01).Moreover,curcumin reduced IL-23 and IL-17 expressions significantly (vs MG,P<0.01).CONCLUSION: Curcumin can inhibit leukocytes infiltration and improve the retinal pathologic changes.Furthermore,curcumin can reduce retinal IL-23 and IL-17 expressions significantly in a dose-dependent manner.

Objective To seek a operation method of quality control of biochemical tests in peacekeeping mission via perspective of evidence-based laboratory medicine .Methods Literatures related to quality control of biochemical tests in international peace-keeping were referred ,compared and discriminated .Combined with 5-year peacekeeping laboratory experience ,a set of feasible ap-proaches were worked out and a practice evaluation was performed in a task period .Results Under the supervision of the quality control system ,providing accurate and reliable test results to the clinical ,developing and implementing quality control of biochemical tests were economical ,practical and reliable ,and could guarantee the effectiveness of reports of biochemical test in peacekeeping medical institutions .Conclusion Evidence-based laboratory medicine is important for quality control of biochemical tests in peace-keeping medical institutions .

?AIM:To investigate and analyze the prevalence and the influencing factors on retinal arteriosclerosis in civil aviators of different ages.?METHODS:Two thousand seven hundred and seventy-eight commissioned civil aviators who received medical examination in Civil Aviation General Hospital from July 2014 to July 2015 were randomly divided into three groups: group A ( 1 311 aviators aged 22-39 ) , group B (618 aviators age 40-49 ), group C(849 aviators age 50-59). Aviators over 40 years old, were divided into two groups: group with retinal atherosclerosis and group without retinal atherosclerosis according to the results of fundus examination. Medical examination data of the aviators were analyzed.?RESULTS: Of 2 778 aviators, 334 ( 12. 02%) were detected with retinal arteriosclerosis, among which 318 aviators were classified as gradeⅠ, and 16 aviators as grade Ⅱ. The retinal arteriosclerosis prevalence of group A, B, and C increased with age, and the difference was statistically significant ( P < 0. 05 ). Biochemical tests showed that the prevalence of hypertension, hyperlipidemia, high fasting blood glucose and overweight increased in group with retinal arteriosclerosis compared with that in group without retinal arteriosclerosis, and the difference was statistically significant(P<0. 05).?CONCLUSION:The prevalence of retinal arteriosclerosis in commissioned civil aviators was 12. 02%, and most of the retinal arteriosclerosis was classified as grade Ⅰ. In aviators over 40 years old, hypertension, hyperlipidemia, high fasting blood glucose and overweight were important factors in the development of retinal arteriosclerosis.

Objective To explore the application of magnetic resonance angiography and virtual reality technique in preoperative planning for sphenoid ridge meningioma. Methods Ten patients with sphenoid ridge meningiomas were examined by brain CT, MRI and MRA before operation. Then the image data were transferred to the Dextroscope system. The images were reconstructed using the Radiodexter software to display the three dimensional image. The tumor and its adjacent anatomic structures could be viewed and the system tools allowed for simulation of the operation, so the full information of the tumor, basilar texture, and nerves and vessels could be obtained. A pre-operative planning was done and was compared with intra- operation situation. Results The virtual reality images of the 10 cases were successfully conducted, and all the procedures were performed according to the pre-operative planning, with a consistent rate of 100%. Radical resection was achieved and all the 10 patients and there were no sequelea. Conclusion Magnetic resonance angiography and the virtual reality system can provide the information of tumor and its adjacent structures, so it can Hp the neurosurgeons no planning the details for operation, contributing to operation safety and tumor resection.

ObjectiveTo observe the clinical therapeutic effect of intra-articular injection with sodium hyaluronate (SH) on osteoarthritis of the ankle.Methods25 patients with osteoarthritis of the ankles (36 ankles) were treated with SH intra-articular injection 2 ml every week for 5 weeks. The degree of pain, swelling and functional disturbance of the ankles were observed to evaluate the effect.ResultsAfter treatment, the degree of pain, swelling and functional disturbance of the ankles improved (P<0.05～0.01). The total efficiency rate was 91.61%.ConclusionSodium hyaluronate injected intra-articular is an effective, ideal and safe treatment for osteoarthritis of the ankle.

The achievement of Nongzheng Quanshu in area of herhalogical textual research was illustrated in this paper. Nongzheng Quanshu recorded the information of 159 kinds of cultivated plants and 473 kinds of wild plants. It also quoted many contents from lots of ancient agriculture hooks related in herbalogical literature. Many agriculture researchers were encouraged to have done much work in area of herhalogical textual research It also included the materia medica hook Jiuhuang Bencao and Yecaipu therein and promoted their delivery.

Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.
