AIM: To retrospectively analyze the effect of different surgical treatment on intraocular foreign bodies, according to different types and position.
METHODS: Clinical data of 46 cases diagnosed with intraocular foreign bodies from June 2010 to April 2013 were retrospectively analyzed.
RESULTS:Intraocular foreign bodies in anterior segment could be removed or magnetically attracted directly, intraocular foreign bodies in posterior segment could be attracted if there was accurate location. Vitrectomis was more favorable for the non magnetic or intraocular foreign bodies in posterior segment. In 46 cases, all intraocular foreign bodies ( 100%) in posterior segment were removed successfully. Among them the functional cure in 33 cases ( 72%) , the anatomical cure in 12 cases ( 26%) , discharged in 1 case (2%).
CONCLUSION:The aim of operation is to reconstruct of eyeball structure preserve and restore visual function. We should find more appropriate mode of operation and timing of surgery according to the foreign bodies'different types and injury of eyeball, reduce complications, preservation eyeball and improve visual function.

AIM:To explore the cataract suspensory ligament rupture and artificial lens implantation suture fixation into capsular bag without capsular tension ring(CTR).METHODS:We reviewed 20 cases of 20 cataract suspensory ligament rupture without CTR intraocular lens (IOL) implantation fixation in our department from Jan.2012 to Dec.2016.The needle crossed into ocular ciliary sulcus, in the equator of the eye ball which suspensory ligament rupture from, then the needle crossed out 1.5mm away from the angle of sclera.Sutures fixed on the IOL, then the artificial lens implantation in the pouch, carried out in accordance with the Z type suture, or to the beforehand prepared triangle scleral flap.The visual acuity, intraocular pressure, the anterior chamber and the IOL position were measured after operations.RESULTS:All of the postoperative visual acuity improved different level.The postoperative best corrected visual acuity(BCVA) was ≥0.8 in 4 eyes(20%), 0.5-0.6 in 7 eyes(35%), 0.3-0.4 in 8 eyes(40%), 0.1 in 1 eye(5%) because of the glaucoma optic atrophy.There were 12 cases with mild corneal endothelium edema, 4 cases exudation membrane in the pupil area, 2 cases hyphema, all of which recovered after treatment.There were 2 eyes with vitreous prolapse in the pupil, 1 case appeared mild IOL center deviation and no special treatment for the vision did not be involved.Followed up for 6mo, displaced stitches or artificial lens shift did not occur.CONCLUSION:Without CTR, the IOL implantation and suture fixation in capsular bag during cataract surgery is a surgical method for basic-level hospitals.

Objective: To explore the placebo-preparation method of Ginkgo Folium Dropping Pills (GFDP) and evaluate its simulation effect objectively, which could provide production and evaluation reference for Chinese materia medica (CMM) placebo. Methods: Taking the placebo-preparation of GFDP as an example, the simulation effect was evaluated from aspects of appearance, color, smell, and taste. It employed three different approaches as possibility of experimental drug, similarity evaluation between placebo and experimental drug and the similarity analysis among the drugs. Results: The two placebo-preparation prescriptions of GFDP have high similarity with the original drug in terms of appearance, color, smell, and taste. The simulation effect of No. 2 placebo-prescription (0.6 g of sucrose octaacetate as bitter agent, 2.1 g of caramel as colorant, 13.3 g of PVP K30 as fillerz and 44.0 g of PEG 4000 as water-soluble bases to prepare 1 000 pills) is better than No. 1 placebo-prescription (1.2 g of sucrose octaacetate as bitter agent, 2.1 g of caramel as colorant, 12.7 g of PVP K30 as filler, and 44.0 g of PEG 4000 as water-soluble bases to prepare 1 000 pills). Conclusion: The placebo-preparation of GFDP conform to placebo requirements of randomized controlled trials. It fills the vacancy of dropping pills form placebo-preparation in CMM and provides method and idea for placebo-preparation and simulation-effect evaluation of CMM.

Objective: To explore the correlation between the high expression of hepcidin and vascular endothelial damage and the intervention effect of tetramethylpyrazine (TMP). Methods: Twenty-four SD rats were randomly divided into four groups: blank control, model, heparin, and TMP groups. Except the rats in the blank control group, the rats in all other groups were fed with high-fat diet for 8 weeks. The rats in the blank control and model groups were injected with normal saline at 2 mL/(kg∙d). The rats in the TMP group were injected with TMP at 40 mg/(kg∙d), and heparin at 5 mg/(kg∙d) was given to those in the heparin treated group. After rats were given medicine for 7 d, the levels of blood lipid, serum hepcidin, NO, ET-1, ROS, MDA, CAT, and SOD were detected. Results: As compared with blank control group, the levels of hepcidin, ET-1, ROS, and MDA in serum were significantly increased in the model group (P < 0.05), while NO, CAT, and SOD were obviously decreased (P < 0.05). Compared with the model group, the levels of hepcidin, ET-1, ROS, and MDA in serum were obviously decreased in TMP and heparin groups (P < 0.05), while NO and CAT were obviously increased (P < 0.05). Conclusion: Hepcidin expression is increased with the vascular endothelial damage aggravated. After rats are given TMP, the level of serum hepcidin and extent of vascular endothelial damage are decreased. It is suggested that TMP has the protective effects on the vascular endothelial function might be correlated to inhibiting high expression of hepcidin.

Objective To evaluate the efficiency of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment. Methods Twenty-three patients with recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment were treated by LNG-IUS. All patients rejected further operation and had no desire of fertility. The visual analogue scale (VAS) scores of pain, menstrual model, weight and serum CA125 level and the volume of ovarian endometriotic cysts before and after 3, 6, 12, 24 and 36 months of treatment were recorded and compared. Results ( 1 ) VAS score:after 12 months of using LNG-IUS, dysmenorrheal, chronic pelvic pain or dyspareunia were relieved significantly. VAS score were dropped from 5.9 ± 2. 3,4. 3 ± 2.0 to 1.0 ± 0. 7,1.4 ± 1. 1 ( P ＜ 0. 01 ). ( 2 )Volum of cysts :after 6 months of using LNG-IUS, the volume of recurrent ovarian endometriotic cysts in 11 patients were reduced from ( 11.4 ± 6. 1 ) em3 to ( 5. 5 ± 3.4 ) em3 significantly ( P ＜ 0. 01 ). At 12 months of follow-up, it suggested that 2 patients' ovarian endometriotic cysts disappeared. At 24 months follow-up,9 patients ovarian endometriotic cysts disappeared ( 3 ) CA125: serum CA125 decreased from ( 65.5 ± 19. 6 )kU/L to (42. 1 ± 13.6) kU/L at 6 months after treatment remarkably (P ＜ 0. 01 ). Continued to decrease after 12 months and then become steady. Irregular bleeding and spotting was the main side effects, weight gain was also observed in few patients. Conclusions LNG-IUS could be used in treatment of recurrent endometriosis after conservative surgery or conservative surgery combined with medical treatment effectively. It could relieve pain, reduce the level of CA125 and decrease the size of ovarian endometriotic cysts. LNG-IUS seems to be an effective, safe, and long term treatment for endometriosis with fewer side effects and better compliance.

Objective To summarize the clinical characteristics, diagnosis and surgical management experiences of 51 cases of pulmonary fungal infections. Methods The clinical data of 51pulmonary fungal infection patients hospitalized in department of thoracic surgery of PLA General Hospital from 1981 to 2008 were retrospectively analyzed. Results The recruited cases included three cases of Candida albicans, 22 of Aspergillus, and 26 of Cryptococcus. The clinical symptoms included cough, hemoptysis, fever, chest tightness, chest pain and asthma. Twenty cases were identified through routine healthy examination. Of chest X-ray and computed tomograply scan, 29 cases presented with solid nodules in the lung, some of which had burrs and spikes; 13 presented with pulmonary cavity with even wall thickness and smooth inner wall including 7 with aspergillar glomera.Forty-eight cases underwent standard thoracotomy operations and 3 cases underwent thoracoscope or thoracoscopy-assisted minithoracotomy. Seventeen underwent pulmonary lobectomies, and 34 wedge resections. There was no operative mortality in the 51 patients. All diagnoses were confirmed by postoperative pathology. There was no relapse during 3- 10 years of follow-up. Conclusions Primary pulmonary fungal infections lack characteristic presentations in clinical manifestations and imaging examinations. Pathology is the evidence for definite diagnosis. Surgical intervention is an effective tool for diagnose and treatment of this disease.

AlM: To evaluate the efficacy of intravitreal ranibizumab in idiopathic choroid neovascularization ( lCNV ) , compare the difference of the curative effect between type I and Ⅱof lCNV by optical coherence tomography ( OCT ) , further provide evidence of the to effectiveness of ranibizumab in the treatment of choroidal neovascularization to guide clinical treatment.METHODS:A retrospective analysis on the clinical data who were diagnosed as lCNV between October 2013 and June 2014 in our hospital were carried out. Totally 31 cases ( 9 cases of type I and 22 cases of type Ⅱ) accepted ranibizumab injection voluntarily. All of the patients were evaluated by ophthalmic examination, funduscopy and OCT before and after the injection, classificated according to OCT results. The best -corrected visual acuity ( BCVA) and maximum of edema thickness after ranibizumab treatment at 3mo follow-up were compared. RESULTS: After statistically analyzed, BCVA and maximum thickness of the retinal lesions of 31 patients (type I9 cases, type Ⅱ 22 cases) before and 1, 3mo after treatment had statistical significance. ln different types of retinal lCNV patients, BCVA and maximum thickness of the retinal lesions before and after treatment had no statistical significance. lt was said that ranibizumab intravitreal injection had effectiveness for lCNV, however, there were no significant effectiveness for typeI andⅡ lCNV.CONCLUSlON: Ranibizumab intravitreal injection has obvious effectiveness for lCNV. However, it has no effect on type I and Ⅱ lCNV. lts safety and long - term complications need for further study.
