?AlM:To evaluate the effect and safety of 1. 8mm coaxial microincision phacoemulsification - trabeculetomy with ultra-thin intraocular lens ( lOL ) implants for treating glaucoma complicated with cataract, and to compare with the traditional 3. 0mm small phacoemulsification-trabeculetomy with foldable lOL implantion.
?METHODS: ln this prospective study, 36 patients ( 36 eyes) with glaucoma and cataract in lnner Mongolia Autonomous Regian People’s Hospital were collected and randomly divided into 2 groups. For the small incision group: 18 cases ( 18 eyes ) underwent 3. 0mm coaxial incision phacoemulsification-trabeculetomy with foldable lOL implantion; ln th microincision group: 18 cases ( 18 eyes ) underwent 1. 8mm microincision phacoemulsification-trabeculetomy with ultra-thin lOL implantion. The two groups were recorded for 1wk, 1 and 3mo of visual acuity, corneal endothelial cell density, surgically induced astigmatism, intraocular pressure ( lOP ) , filtering bleb and complications. Pearson’s Chi-square test ande t-test were used to determine differences between the two groups.
?RESULTS:At 1wk postoperatively, visual acuity in the microincision group was better than that of small incision group, the difference was statistically significant ( P<0. 05). At 1 and 3mo, the difference in corrected visual acuity between the 2 groups had no significant difference (P>0. 05). At 1wk, 1 and 3mo, there was a significant different between the 2 groups in surgically induced astigmetism (P<0. 05). At 1wk postoperatively, there was a significant difference in corneal endothelial cells density between 2 groups (P<0. 05). But there were no significant difference at 1 and 3mo ( P > 0. 05 ). lOP reduced after surgy ( microincision group: 15. 26 ±3. 12mmHg, small incision group: 14. 57±2. 86mmHg), there was no significant difference between the 2 groups (P>0.05). There was no significant different between the 2 groups in blebs (P>0. 05). Neither iris injury, posterior capsule rupture nor anterior chamber bleeding complications was found in any groups.
?CONCLUSlON: TBy compared with traditional 3. 0mm coaxial small incision phacoemulsification -trabeculectomy with foldable lOL implantion, 1. 8mm microincision phacoemulsification-trabeculectomy withe ultra- thin lOL implantion can effectively reduce the astigmatism operation. This operation is safe, effective, convenient surgy for treating cataract and glaucoma.

Objective: To investigate the effect of nicotine on insulin sensitivity in rats and its relationship with PPAR-γ. Methods: Male Sprague-Dawley rats (10-11 weeks old) were randomly divided into saline group and nicotine group, and the two groups were further divided into 3 subgroups: 1 week, 3 weeks, and 6 weeks subgroups according to the time they were treated by different agents. Rats were subcutaneously injected with saline (saline group) daily or nicotine (3 mg·kg-1·d-1, nicotine group) for 1 week, 3 weeks, and 6 weeks. The body weights of animals were recorded on a weekly basis. Insulin tolerance tests were performed at 3 weeks and 6 weeks after treatment, and the serum parameters were determined at 1 week, 3 weeks, and 6 weeks after drug administration. At the end of the experiment, fat tissue weights of different body parts were weighed, and PPAR-γ expression in the subcutaneous fat and visceral fat was detected by Western blotting analysis. Results: The body weight increase of rats was inhibited after nicotine treatment. Insulin sensitivity of rats was significantly enhanced 3 weeks and 6 weeks after nicotine treatment (P<0.05), serum triglyceride level was decreased significantly at 3 weeks after nicotine treatment (P<0.01), insulin sensitivity indices were increased after 6 weeks (P<0.05), and both the weight and relative weight of subcutaneous and visceral fat tissues were significantly decreased 6 weeks after nicotine treatment (P<0.01), with the visceral fat decreased more severely than that of the subcutaneous fat. PPAR-γ expressions in the subcutaneous fat and visceral fat tissues were not significantly different between saline and nicotine treated groups. Conclusion: Nicotine can improve insulin sensitivity in rats, which is partly due to the fact that nicotine can decrease the serum triglyceride levels and fat tissue, especially the visceral fat tissue, but has no relation with PPAR-γ protein expression in fat tissue.

Objective To analyze the morphologic characteristics of the single infarct in the territory of perforating arteries which arise from the middle cerebral artery (MCA),and further to investigate the association between the type of cerebral infarction and the isolated stenotic disease of the ipsilateral MCA.Methods Fifty-five patients with acute ischemic stroke who were admitted to the Department of Neurology,Peking Union Medical College Hospital,Beijing,China during January 1,2005 and December 31,2006 were identified.All of the patients had a single acute infarction in the territory of the MCA perforating arteries revealed on diffusion weighted imaging (DWI).Transcranial Doppler (TCD) and magnetic resonance angiography (MRA) were performed for all patients.Patients with stenesis >50% of proximal internal carotid artery and potential cardiac sources of embolism were excluded from the study.Patients were classified into 2 groups according to the presence of the atberosclerotic stenosis of the ipsilateral MCA: patients with or without MCA stenosis.Size of the lesions was measured including the diameter,area and volume.The infarcts with a diameter less than 2 cm were classified as lacunar infarcts; those bigger than 2 cm were classified as the striatocapsular infarcts.The infarcts on DWI was seen in basal ganglia,the body of lateral ventricle and beth.The concomitance of subcortical multiple small old infarcts or leucoariosis on T2>WI-MRI between the two groups was assessed.Results Among these 55 patients,14 (25.5%) had stenosis of the ipsilateral MCA and 41 (74.5%) had a normal MCA.In the group of MCA stenosis,71.4% patients were lacunar infarcts; 67.3% patients were also lacunar infarcts in the normal MCA group.There was no significant difference between the two groups (χ2=0.147,P=0.701).No significant difference in the diameter,area and vo|ume of the infarcts was found between the two groups.The basal ganglia,the body of lateral ventricle and both of these places involvement accounted for 31.7% ,17.1%,51.2% in the normal MCA group; 35.7%,28.6%,35.7% in the stenotic MCA group.No significant difference was found (χ2=1.272,P=0.529).Twenty-three (56.1%) patients had concomitant of small old subcortical multiple infarcts or leucoariosis in the normal MCA group and 3 (21.4%) in the MCA stenosis group,and there was a significant difference between the two groups(χ2=5.033,P=0.025).Conclusions A series of pathologic mechanisms are supposed to cause the single infarction in the territory of MCA perforating arteries.Stenosis of MCA is an underlying cause in addition to perforating artery diseases.There is no significant difference in the size,volume or distribution of the lesions between the two groups.The concomitant of subcortical multiple small old infarcts or leucoariosis may demonstrate the perforating artery disease.

Objective To investigate the role of basic fibroblast growth factor（bFGF）on the vascularization of bone matrix gelatin（BMG） embedded vascular bundles in femoral anteriomedialis in the rabbits.Methods A longitudinal incision was done at the hyper-knee joint of femoral anteriomedialis in the Japan big ears white rabbit.Thirty six rabbits were divided into group A（n =12,arteria saphena and vena saphena were liberated and embeded to the groove of BMG soaked by 2 μg/ml bFGF0,group B（n =12,arteria saphena and vena saphena were liberated and embeded to the groove of BMG untreated）,and group C（n =12,the BMG untreated were directly implanted）.The rabbits were sacrificed at 4 weeks,8 weeks and 12 weeks after the surgery respectively by perfusing ink.After the implants were dislodged,transparent specimens were made and Masson stained for histological observations and quantitative analysis.Results After 12 weeks of operation,the neovascularization arranged in an ordered manner in group A,gradually trended to be orderly in group B,and were cluttered mainly on the edge of the implants in group C.The osteogenic and neovascularization areas of group A were the largest on each time point.Conclusion bFGF could promote the vascularization of BMG embedded vascular bundle.There was a positive correlation between osteogenesis and vascularization.

AIM: To study the effects of fructose-1,6-diphosphate (FDP) on adriamycin (ADR)-induced calcium and sarcoplasmic reticulum Ca 2+-ATPase activity in cardiomyocytes of rats. METHODS: Rats were treated with ADR by intraperitoneal injection (2 5 mg?kg -1 body weight) once every two days for 11 days, and then ADR-treated rats were intervened by FDP at different dosages (ip) once every other day for 41 days. Enzyme linked immune absorption assay (ELISA) was employed to detect froponin I (CTnI). CK-MB was examined by monoclonal antibody. Intracellular free calcium concentration was measured on fluorescent spectrophotometry and SRCa 2+-ATPase activity was examined by inorganic phosphate. RESULTS: FDP (300, 600, 1 200 mg?kg -1) significantly reduced the levels of CTnI and CK-MB in serum. Decreased calcium and increased SRCa 2+-ATPase activity in cardiomyocytes were also observed when ADR-treated rats were intervened by FDP (P

OBJECTIVE: To put forward a method of construction of the safety evaluation platform related to formula-medicine dose of TCM because of the lack of the dose-effect relationship research and the insufficient of safety monitoring in Chinese medicine. METHODS: Under the guidance of Chinese medicine theory, an ADR (adverse drug reaction)/ADE (adverse drug event) monitoring scale with TCM characteristics was developed based on patients reporting, thus to promote positive and prospective evaluation researches related to formula-medicine dose. On the basis of the ADR/ADE data base, the safety monitoring module will be formed then. RESULTS AND CONCLUSION: The safety evaluation platform related to formula-medicine dose is supposed to be structured.

OBJECTIVETo study clinical results of reduction and fixation under arthroscopy for the treatment of osteochondrotical lesion in the knee.

METHODSFrom December 2012 to December 2013, 4 patients with the knee joint osteochondritis lesion and free bone fragments were treated with arthroscopy to detect the stripped cartilage, and then the cartilages were reduced with small incision and fixed by cartilage nail. There were 3 males and 1 female, with age of 15, 15, 20 and 27 years old. The durations of the disease were 1 d, 5 d, 1 month and 1 year. All the patients had swelling and effusion in the knee joint, and the floating patellar test was positive. CT examination showed bone defects and loose bodies. The Lysholm, VAS, and Tegner scale were used to evaluate the knee joint functions before and after operation.

RESULTSAll the patients underwent successful surgery. Postoperative CT showed good location of the cartilage without loss of reduced bone and cartilage. All the patients were followed up, and the duration ranged from 10 to 13 months, with a mean of 12 months. In one patient, arthroscopy examination was conducted for a second time to examine the connection of the fracture part to the surrounding cartilage, and it showed that the internal fixator was not absorbed. The Lysholm, VAS and Tegner scale of all patients were better than those before operation.

CONCLUSIONTreatment of osteochondritis lesion with the fixation of absorbable cartilage nails may reconstruct the integrity of articular surface and recover the stability of joints, and it is an effective treatment method.

Hyperlipidemia is an important risk factor of cardio-/cerebrovascular disease, and reducing lipids has become an important project for itsclinical preventing and treating. Western medicine, with its confirmative efficacy and clear mechanism, has played an irreplaceable role. Along with the development of modern medicine, integrative medicine has gradually become a growing trend in regulating blood lipids metabolism. It not only could make up the insufficient power for Chinese medicine in lowering lipids, but also could reduce adverse reactions and economic costs brought by long-term administration of Western medicine. As a modern practitioner of Chinese medicine, we should keep clear that integrative medicine regulating blood lipids metabolism does not mean a simple combination of traditional Chinese medicine and Western medicine. We should treat it guided by systematic theories. We combine disease identification and syndrome differentiation, guide lipids lowering by integrative medicine including selecting Western drugs for blood lipids lowering, Chinese medical prescriptions for syndrome typing, and effective Chinese herbs based on modern pharmacologies.
