Objective To observe the curative effect of surgical treatment for eyelid basal cell carcinoma. Design Retrospective case series. Participants 33 cases with eyelid basal cell carcinoma. Methods 33 cases with eyelid basal cell carcinoma treated with surgery, standard excision in 17 case and Mohs micro excision in 16 cases were analyzed, postoperative appearance and function of re- eonstruetiiv eyelid, reeurence rate and survival rate were observed by follow-up survey. Main Outcome Measures Postoperative ap- pearance, function of reconstruetiiv eyelid, recurence rate and survival rate. Results After 6 month ~ 5 years follow-up survey with an average of 2.5 years, 28 of 29 cases obtained normal eyelid appearance, 1 case with lower eyelid gentle ectropium. 11 cases showed hy- perpigmentation in skin-grafting area in early stage, and became normal in half a year. Eyelid function of 29 cases were normal. Tumour relapse was seen in one case 2 years after standard resection,the cure rate was 94.12%. No tumor relapse was seen in group of mohs micro resection, the cure rate was 100%. Within five years postoperation, there was no death case caused by basal cell carcinoma re- lapse, except one dying from myocardial infarction and another dying of eerebrovaseular disease. Conclusions Operational excision is an effective approach for eyelid basal cell carcinoma. The effect of mohs micro resection is better than the one of standard resection. With dissociate skin grafting, fluctuate tarsal transmigration and dissociate skin grafting, eyelid appearance and function recover well.

Mucosa-associated lymphoid tissue (MALT) lymphoma often occurs in the stomach as well as the head and neck.This disease has characteristics of multi-site dissemination and indolent development,and about 80% of MALT lymphoma patients are in early stage.Helicobacter pylori (Hp) eradication is the main method for treating early-stage Hp-positive gastric MALT lymphoma.For patients with other types of early-stage MALT lymphoma and those with gastric MALT lymphoma who failed Hp eradication therapy,radiotherapy has a good clinical effect.In recent years,radiotherapy target volume has changed from the involved field to the involved site,and the dose has been decreased.This article provides a review of the above aspects.

AIM:To find out the mean corneal spherical aberration and its changes with age in Kaifeng population.
METHODS: A total of 466 eyes of 427 Kaifeng subjects with cataract, whose age ranged from 52 to 75 years old, were divided into three groups according to the age. All the subjects were included in measuring K-readings of cornea, the corneal anterior and posterior surfaces of the spherical aberration and the total corneal spherical aberration using Pentacam(Oculus, Germany) at the 6-mm optical zone.
RESULTS:The mean corneal spherical aberration( CSA) of the whole groups was 0. 339±0. 153μm. Patients from 50 to 60 years old had CSA of 0. 322±0. 137μm, 0. 326±0.157μm was the CSA of the patients from 60 to 70 years old, while those from 70 to 80 years old have a CSA of 0.401 ± 0. 182μm. The corneal K - readings had no correlation with the total corneal spherical aberration ( r=0. 034, P>0. 05), anterior surfaces CSA, posterior surfaces and total CSA were positively correlated with age ( r =0.253, 0. 327, 0. 233, all P<0. 01).
CONCLUSION:CSA is varied among the population and CSA of elderly in Kaifeng area are slightly higher than white people, and positively correlated with age.

Objective: To design and prepare a fiberoptic bronchoscopy training box and to study its primary application. Methods: According to the length of optical fiber, the height, the length and the width of the box were set at 400 mm, 200 mm and 200 mm. The box contained 6 layers from the top to the bottom: the top-layer, layer-A, layer-B, layer-C, layer D and the bottom layer, with the area of each layer being 200 mm × 200 mm and the distance between each 2 layers was about 80 mm. According to the diameter of optical fiber, the diameter of the holes was set at 6 mm. Except for the bottom-layer, the other 5 layers had different numbers of holes: the top-layer and layer-A only had a central hole(central hole in every layer was defined as hole-0), layer B had 5 holes(hole-0 to 4), layer C had 9 holes(hole-0 to 8), layer D had 17 holes(hole-0 to 16). The training started from the top-layer. The orders were given according to the layers and the numbers of the holes and the orders were executed, then the box was open to examine the outcome of the execution. Results: We successfully designed a fiberoptic bronchoscopy training box. If the training instruction order was A0-B2-C4-D7, the trainees should manipulate the optical fiber via the central hole in top-layer and layer-A, hole-2 in layer B, hole 4 in layer-C, and hole-7 in layer-D. The results of manipulation can be examined after opening the door. Conclusion: The fiberoptic bronchoscopy training box is a easy-to-operate and practical tool for training of fiberoptic bronchoscopy manipulation.

Objective: To study influence of acute hypoxia on the current of voltage-gated potassium channel (IK) in pulmonary artery smooth muscle cells (PASMC) of rats. Methods: A total of 20 male SD rats were randomly and equally divided into normoxic control group and acute hypoxia group. The rats in acute hypoxia group were kept in hypoxic chamber for 8 h before experiment. Whole cell patch-clamp technique was used to record IK in PASMC. Results: Acute hypoxia significantly decreased the IK density in PASMC of rats. During -60mV to -10mV of resting membrane potential（RMP）, acute hypoxia did not significantly decrease peak IK density in PASMC of rats, P>0.05; At 0 mV, acute hypoxia significantly decreased the peak IK density in PASMC [from（38.1 ± 5.2） pA / pF decreased to（9.82 ± 2.1） pA / pF ,P<0.05], then along with RMP increase in PASMC, the decreasing amplitude of peak IK density in PASMC gradually increased（P<0.05）; From + 30 mV to+ 60 mV, the decreasing amplitude of peak IK density in PASMC further significantly increased（P<0.01）; At + 60 mV the peak IK density decreased from（38.1 ± 5.2） pA / pF to（9.82 ± 2.1） pA / pF , and the decreasing amplitude reached (46.8±3.3)%. Conclusion: Acute hypoxia can decrease Kv current in PASMC of rats, leading to hypoxic pulmonary vasoconstriction.

Objective To construct the immune genes expression profile database of multiple sclerosis (MS) and to screen the high immune related candidate genes by using microarray analysis Methods Polymerase chain reaction (PCR) products on behalf of 484 immune related genes from mixed tissue library were assembled on the modified Oako glass slide The general RNA from MS patients and normal persons lymphocytes was transcripted to cDNA by RT PCR and labelled with cy 3 and cy 5 The two probes were mixed and hybridized with the above mentioned gene chips Scan array 4000 was used for scanning the hybridizing signals and GenePix Pro3 0 for date analysis Results Of the total 484 double genes monitored,22 genes of group one showed changes in expression level of the ratio outside 0 5 and 2.0;27 genes differ in group 2;72 genes change in group 3 With the same consistent gene ID of the double genes, the group one was 6,the group tow was 9 and the group three was 30 Conclusions These results show that the different expression of immune related genes might occur between MS patients and normal persons It might also afford a view of the changes that these genes should be probably related to the occurrence, development or progress of MS The cell immune related genes might be the important and most immune related genes involved in MS pathogenesis The results suggest the deeper insights into the mechanism,relapsing and treatment of MS

At present, the percutaneous transhepatic cholangiodrainage (PTCD) and the self-expandable metal stent implantation are commonly recognized as an effective treatment for inoperable malignant biliary obstruction, but the restenosis of biliary stent significantly affect the therapeutic result and prognosis.Percutaneous transhepatic intraductal radiofrequency ablation can be used together with biliary stent implantation, which can prolong the patency time of biliary stent and control the local tumor at the narrowed segment, thus, the therapeutic effect of malignant biliary obstruction can be reliably improved. As a kind of newly-developed therapy, its clinical safety is especially important. This paper aims to make a review about the safety of percutaneous transhepatic intraductal radiofrequency ablation combined with biliary stent implantation in treating malignant biliary obstruction.

Objective To investigate the clinical and imaging features of cerebral cortical vein thrombosis (CoVT). Methods The clinical data of 13 inpatients with CoVT were enroled from September 2010 to September 2015. The etiology, clinical symptoms, imaging features, and differential diagnosis of CoVT w ere summarized and analyzed. Results Among the patients, there w ere 7 females (53.85%) and 6 males (46.15%). Their age ranged from 18 to 59 years (mean 34.23 ±12.08). The most common clinical manifestations were headache (9 patients) and seizures (9 patients). The 13 patients had cerebral parenchymal involvement and they al received anticoagulant therapy. Conclusions The clinical symptoms of CoVT are various. Seizures and headache are the most common symptoms. Most of patients are accompanied by brain parenchymal lesions and venous sinus thrombosis. When patients have headache and seizures, and head images suggest hemorrhagic infarction, imaging examination of the improvement of the cerebral venous system thrombosis is recommended.
