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.

To study the chemical constituents of Cirsium setosum (Willd.) MB., 70% ethanol extract of the aerial parts was subjected to column chromatography. One new phenylpropanoid glycoside, sinapyl alcohol 9-O-(E)-p-coumaroyl-4-O-beta-D-glucopyanoside (1) was isolated, along with three known compounds: lycoperodine-1 (2), apigenin-7-O-(6"-(E)-p-coumaroyl)-beta-D-galactopyranoside (3) and quercetin (4). The structures were elucidated on the basis of spectral and chemical evidence. Compound 2 was obtained from Cirsium genus for the first time, compounds 3 and 4 were obtained from this plant for the first time.

Objective To investigate the association between resting heart rate(RHR)and dyslipidemia. Methods A total of 772 subjects(average age:40. 1 ± 11.8 years;male:74. 7%)were recruited by random sampling method from medical checkup population. The survey data included resting heart rate,blood lipid and other metabolic parameters. The subjects were divided into three groups according to the RHR,as RHR ＜ 70 bpm,70 bpm ≤ RHR ＜ 80 bpm,RHR ≥ 80 bpm groups. Results RHR were positively correlated with triglyceides (TG),as well as total cholesterol(TC)(r = 0. 316 and r = 0. 110 respectively,all P value ＜ 0. 05). Low RHR had no significant correlation with HDL-C or LDL-C. The prevalences of hypertriglyceridemia and hypercholesterolemia increased significantly with RHR elevation(χ2 = 7. 214 and 5. 285 respectively,all P value ＜ 0. 05). By logistic regression analysis,adjusted for BMI,gender,serum creatinine,serum uric acid,fasting blood glucose and age,we found that compared with RHR ＜ 70 bpm group,the odds ratio(OR)values for hypertriglyceridemia was 1. 540 (95%CI:1. 086-2. 185,P=0. 016)in 70 bpm≤RHR ＜80 bpm group and 1.640(95% CI:1.067 -2.523,P =0. 024)in 80 bpm ≤ RHR group,and the OR values for hypercholesterolemia was 1.197(95 % CI: 0.749 - 1.913,P=0.453)in70 bpm≤RHR ＜80 bpm group and 1.814(95% CI:1. 036-3. 177,P =0.037)in 80 bpm≤RHR group. Conclusions RHR is independently and positively correlated with the prevalence of hypertriglyceridemia and hypercholesterolemia and the blood levels of both lipid. RHR has no significant correlation with HDL-C or LDL-C level.
