1.Updated Progress in Diagnosis and Management of Barrett ’s Esophagus --- Comparisons between New Guidelines of America,Britain and China
Chinese Journal of Gastroenterology 2014;(8):449-453
Barrett’s esophagus is associated with esophageal adenocarcinoma and cardia cancer,although it has no significant influence on individual’s expectation of life and the canceration rate is comparatively low. However,Barrett’s esophagus has big burden on the psychology and economy of patients. At present,there are still some debates about the diagnosis and management of Barrett ’s esophagus. American Gastroenterological Association, British Society of Gastroenterology and Chinese Society of Gastroenterology have updated their guidelines on Barrett’s esophagus. In this review,we introduced the updated progress in diagnosis and management of Barrett’s esophagus according to these three new guidelines,and compared the similarities and differences between these guidelines.
2.Variations of Endocrine after Brain Injuries and Its Neuropathological Mechanism(review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(11):929-930
In the acute phase of traumatic brain injury or cerebrovascular disease,disorders of hypothalamic-pituitary-cortical axis,hypothalamic-pituitary-thyroid axis and hypothalamic-pituitary-gonad axis may exist.The main cause is primary or secondary impairment of hypothalamus as well as pituitary after brain injury.Most of the variations of endocrine after acute brain injuries may be temporary and reversible,but some patients will accompany with hypopituitarism or neuroendocrine deficiency.It is important to set a guideline to decide who and when to test.Hormone replacement therapy should also be verified if it can improve the outcome of patients with brain injuries.
3.Experiment study on radial optic neurotomy in cats' eyes
International Eye Science 2006;6(4):765-768
AIM: To explore the anatomical changes of the optic nerve head in cats after radial optic neurotomy (RON).METHODS: The normal anatomic data were obtained from 12 healthy cats. A total of 18 healthy cats were used in the experiment, which were divided into four groups: each operative group was executed at the :Lst, 15th, 30th, 90th day after undergoing RON unilaterally.(six in 1st group). The enucleated eyes of each operative group were cut section routinely and embedded in paraffin, the cross sections were stained by special staining.RESULTS: At the 1st day after operation, the incision came into being and connected with cerebral subarachnoid space of orbital optic nerve. At 15th day, incision was fusiform and hyperplastic neuroglial cells and fibroblasts aggregated at the incision. At 30th day, there was obvious proliferation of type fibril at the neurotomy. The aligned texture of collagen fibril of the lamina cribrosa near the incision was moved close to each other. At the 90th day, a discrete scar was noted at the site which reached the cribriform and sclera.CONCLUSION: RON can cut scleral ring and piamater of optic nerve sharply. The incision of RON connects with subarachnoid space of orbital optic nerve and becomes broaden gradually at the site of scleral ring. The potential role of incision of RON is relevant to the subject.

In order to investigate the lesion' s extention and the infiltrated deepth and the metastasis of the tumors preoperatively ,endoscopic ultrasonography (EUS) was performed in 28 patients with ampullary carcinoma and 18 patients with extrahepatic bile duct carcinoma. forty six patients underwent surgical ex- plorations. A radical resection with detailed pathological study was done for 22 resectable cases of ampullary carcinoma and all the 18 cases of extrahepatic bile duct carcinoma. Carcinoma of ampulla of Vater and ex- trahepatic bile duct were assessed and staged preoperatively according to the TNM staging system. The re- sults of EUS were compared with surgical explorations and pathological findings for evaluating the accuracy of preoperative staging of EUS. The accurate rate of EUS in assessing the extent of cancer invasion was 8l.8% for ampullary carcinoma, 72. 2% for extrahepatic bile duct carcinoma. The accuracy of EUS in pre- dicting regional lymph node metastasis was 59% for ampullary carcinoma , and 61.6% for extrahepatic bile duct carcionoma. invasion of portal vein was correctly predicted by EUS in 2 out of 3 patients of ampullary carcinoma. All the 3 cases of liver metastasis were not detected by EUS. EUS is a more accurate diagnostic method in judgement of invasive extent of ampullory carcinoma and extrahepatic bile duct carcinoma preop- eratively , but less accurate for metastasis of the tumors.

AIM: To report a case of wet age-related macular degeneration (AMD) treat with multiple transpupillary themotherapy (TTT) and choroidal neovascularization (CNV) disappeared but retinal pigment epithelial(PRE) and choroidal atrophy occurred with a low vision at the end point.METHODS: Clinical data including fundus hotographs, fundus fluorescein angiography (FFA), indocyanine angiography (ICGA) and optical coherence tomography(OCT) was reviewed.RESULTS: A 72-year-old man complained about blurred vision of his left eye and FFA revealed polypoidal choroidal vasculopathy (PCV) in the macula. His left eye had stable vision of 0.1 for 6 years without any treatment of CNV. About 2 years later, his right eye presented a piece of CNV. During the period of 3 years, the lesion remained more (3×5 PD) and less (1×2PD) in size with remarkable exudates and bleeding, and 7 sessions of TTT were applied with 80-280mW, 2mm of spot, and 60 seconds exposure and with the interval of 3 months or more. The CNV lesion finally disappeared, but there left a white area in the macula and vision decreased from 0.3 to 0.04.CONCLUSION: Although CNV lesion can be eliminated by TTT, obvious atrophy of RPE cells and the choroids can happen and this may not be of help for patient vision. It suggests that the parameters of TTT will be lower than 120 mW/mm and limited less two sessions if applicable, especially for Asia people.

Objective To study on the effectiveness of endoscopic ultrasonography (EUS) in diagnosing common bile duct (CBD) stones. Methods Accuracies for the diagnosis of choledocholithiasis by abdominal ultrasonography ( B-US) and computed tomography (CT) are compared with those by EUS in 45 patients. Final diagnosis is determined by endoscopic retrograde cholangiography ( ERC) with or without sphincterotomy ( EST) or operative exploration. Results Forty-three out of 45 patients with choledtx-holithia sis were diagnosed by EUS, of them 2 patients with slight dilation of common bile duct in which stones were confirmed in the proximal part of common bile duct by EST. In 2 out of 43 patients EST and operation diagnosed cholecystolithiasis instead of choledocholilhiasis. The sensitivity and the positive predictive value are both 95%. With 41 patients choledocholithiasis were confirmed by EUS, the sizes of stone were diameter ≥ 10mm in 5 patients, 6-9 mm in 10 patients and ≤5mm in 26 patients. Four out of 45 patients were suspected to have CBD stones and 2 patients had tumor in periampullar area by B-US. Three patients were diagnosed to have CBD stone and 1 patient was suspected to have tumor in peri-ampullar area by CT. Conclusions EUS appears to be the best diagnostic tool for the diagnosis of choledocholithiasis compared with other noninvasive procedures such as B-US and CT. EUS is at least as sensitive as ERC especially in diagnosis of small CBD stones.
