?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.

Objective To investigate the relationship between the changes of serum total bilirubin(TBil) and hybrid muscle crea-tine kinase isozyme(CK-MB),and its clinical implication in neonates with hypoxic-ischemic encephalopathy (HIE). Methods The levels of TBil and CK - MB were measured in 49 neonates with HIE (15 mild cases, 20 moderate cases and 14 serious cases), and 31 normal neonates on the first day and the fourth day after birth. Results The levels of TBil on the first day after birth were significantly higher than those in normal neonates;the levels of TBil were correlated with the severity of HIE(P

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To evaluate the efficacy of decortication by video-assisted thoracic surgery (VATS) in pa﹣tients with tuberculous empyema, and discuss its indications. Methods 60 patients with tuberculous empyema who underwent decortication by VATS for surgical management from December 2010 to December 2015 were included. Under a thoracoscope, we cleaned up the pus, separated adhesions, scraped granulation tissues and caseous necrosis on the inner wall of the abscess cavity, and stripped the thickened fiberboard of the parietal and visceral pleurae. Af﹣ter the procedure, sufficient drainage and antituberculosis therapy were carried out. Results All the patients in this group were operated successfully. All the patients were cured without perioperative death and complications. No re﹣currence of empyema was observed at the follow-up examination from 2 months to 5 years, and suffered pulmonary reexpansions were better. Conclusions The decortication by VATS for tuberculous empyema is safe, effective, mini﹣mally invasive. The imaging manifestations of pleural thickening in 1 cm, no obvious calcification, no serious lesions in the lungs are the indications for the operation.

Objective To investigate the localization and surgical outcome of epileptogenic nidus of post-traumatic epilepsy. Methods A retrospective analysis was performed on clinical data of 62 patients with post-traumatic epilepsy treated microsurgicallly from November 2005 to May 2009. There were 48 males and 14 females, at age range from 11 to 48 years old (average 28.8 years old). The epileptogenic nidus in 59 patients was localized based on clinical manifestations, visual electroencephalography (V-EEC) imaging and electrophysiological findings and that in three patients localized by implanted intracranial electrodes. Under electrocorticogram (ECoG) monitoring, we resected cerebral malacia in 36 patients, removed both malacia and epileptogenic nidus in 15, and partially resected cerebral malacia combined with cortex thermocoagulation in 11. Results The follow-up for 6-33 months showed that there were 32 patients at grade Ⅰ , 17 at grade Ⅱ , nine at grade Ⅲ and four at grade Ⅳ according to Engel classification system. Conclusion V-EEG is an important method for pre-operative localization of epileptogenic nidus of post-traumatic epilepsy. Microsurgical management can attain favorable outcome under ECoG monitoring.

OBJECTIVETo study the effect of Flos Daturae alkaloids (FDA) on TGF-beta1-1uuuu;U epithelial-mesenchymal transition (EMT) of human pulmonary adenocarcinoma A549 cells.

METHODSA549 cells in vitro cultured were randomly divided into 5 groups, i.e., the blank control group, the TGF-beta1 group, the low dose FDA group, the medium dose FDA group, and the high dose FDA group. The morphologies of A549 cells were observed. Expressions of cytokeratin (CK)-19 and alpha-smooth muscle actin (alpha-SMA) were detected by Western blot and real-time PCR at 24, 48, and 72 h, respectively.

RESULTSA549 cells in the TGF-beta1, group turned from cobblestone to spindle shape gradually. Those in low, medium and high dose FDA groups showed similar shapes to those of the TGF-beta1 group. There was no statistical difference in the morphology of A549 cells among the 3 dose FDA groups (P > 0.05). Western blot showed that, when compared with the blank control group, the expression of CK-19 was down-regulated, but the expression of alpha-SMA was up-regulated in the TGF-beta1 group (P < 0.01). Compared with the TGF-beta1, group, the expression of CK-19 was up-regulated, but the expression of alpha-SMA was suppressed in low, medium and high dose FDA groups (P < 0.01). The CK-19 expression obviously increased, but the alpha-SMA expression was suppressed in high dose FDA group at 72 h (P < 0.01). Real-time PCR results showed, as compared with the TGF-beta1 group, the mRNA expression of CK-19 was increased, but the mRNA expression of alpha-SMA was reduced in low, medium and high dose FDA groups (P < 0.01).

CONCLUSIONSFDA had no effect on EMT morphological changes of TGF-beta1 induced A549 cells. FDA could reverse characteristic markers of A549 cells during EMT to some extent, such as expressions of CK-19 and alpha-SMA. The expression of CK-19 (as the epithelium marker) increased and the expression of alpha-SMA (as the mesenchymal marker) was reduced. Besides, they were most obviously seen in the high dose FDA group at 72 h in a dose- and time-dependent manner.

AIM　To investigate protective effects and mechanism of tanshinones on ischemia-like injury models. METHODS　Six ischemia models including hypoxia, hypoglucose, oxidant injury, caffeine injury, nitric oxide neurotoxicity and excitatory amino acid injury were used to assay the anti-ischemic roles of tanshinones in cultured primary cortex neurons. The changes of injuried cortex neurons were observed by the way of morphological examination, and live neurons of crystal violet staining were measured according to absorbent index. RESULTS　It was found that tanshinones possessed obvious protective effects on primary neurons in injury models by the way of morphological examination. Crystal violet staining also indicated that tanshinones increased number of live neurons in injury models significantly. The protective effects of tanshinones on models of oxidant injury, caffeine injury and NMDA injury were superior to other injury models. CONCLUSIONS　83.0 μmol*L-1 tanshinones protected rat cortex cells from all injury models effectively in vitro.

Objective: To explore the pattem of lymphatic metastasis and influencing factors of thoracic esophageal carcinoma. Methods: We reviewed the pathological specimens from 229 esophageal carcinoma patients who underwent radical esophagectomy with two-field lymphadenectomy. A total of 2,458 lymph nodes were dissected. We analyzed the lymph node metastasis pattern of the primary tumor in different loca-tions and the corresponding influencing factors such as pathological T stage, tumor length, pathological mor-phology and tumor differentiation. Results: Lymph node metastasis rates were 44.5% (102/229) and 10.5% (258/2458), respectively. For patients with upper thoracic esophageal carcinomas, lymphatic metastasis rates in the superior mediastinum, the middle mediastinum, the inferior mediastinum and the abdominal cavity were 19.0%, 6.7%, 9.8% and 12.2%, respectively. For patients with middle thoracic esophageal carcinomas, the rates were 26.1%, 7.4%, 11.8% and 11.9%, respectively. For patietns with lower thoracic esophageal carcino-mas, the rates were 0, 1.6%, 5.3%, and 10.0%, respectively. Lymphatic metastasis rate in T_1, T_2, T_3, T_4, stage cancer were 28.6%, 43.8%, 47.6%, and 31.3%, respectively; the rate of positive lymph nodes were 7.9%, 10.8%, 10.7%, and 10.8%, respectively, with no significant differences among the four stages (x~2=2.733, P=0.435 and x~2=0.686, P=0.876). Lymphatic metastasis rate and rate of positive lymph nodes in patients with tu-mor ≤3cm, 3 to 5cm, and >5cm were 45.2% and 43.4%, 46.2% and 9.1%, and 11.6% and 11.7%, respective-ly, with no significant differences (x~2=0.094, P=0.954 and x~2=3.933, P=0.140). Lymphatic metastasis ratios of the pathological morphology in medullary, ulcerative, mushroom and stenotic types were 14.0%, 9.6%, 4.3% and 18.3%, respectively (x~2=19.292, P=0.000). Lymphatic metastasis rate and rate of positive lymph nodes of squamous cell carcinoma of moderately and poorly differentiation were 42.5%, 75.0% and 9.5%, 18.6%, re-spectively (x~2=4.852, P=0.028 and x~2=11.323, P=0.001). Patients with squamous cell carcinoma of poorly dif-ferentiation had a higher rate of lymph node metastasis. Conclusion: Lymphatic metastasis of esophageal car-cinoma metastasize widely even if in early T stage. Pathological morphology and tumor differentiation are re-lating facors of lymph node metastasis of thoracic esophageal carcinoma.
