·临床研究·中国当代医药2021年1月第28卷第3期CHINA MODERN MEDICINE Vol.28No.3January 2021白癜风为黑素细胞破坏所导致皮肤白斑疾病,流行病学显示我国人群白癜风患病率为0.56%,其中10%患者伴有白癜风家族史[1]。

临床研究显示,白癜风发生同自身免疫系统疾病、遗传及化学物质及接触有直接关联,当前白癜风的治疗以药物治疗、表皮移植、光疗、脱色治疗为主,以改善皮肤外观并恢复周围皮肤颜色[2]。

光疗是临床治疗白癜风的常用方法,但光疗308nm 准分子激光+他克莫司治疗成人面部白癜风的效果陈菁李玉良彭圣炽易圣刚彭艳萍梁清江西省萍乡市人民医院皮肤科,江西萍乡337000[摘要]目的探讨308nm 准分子激光+他克莫司治疗成人面部白癜风的效果。

方法选取2018年1月~2019年12月江西省萍乡市人民医院收治的70例面部白癜风患者,按随机投掷法分为参照组(n =35)和研究组(n =35)。

参照组给予308nm 准分子激光照射治疗,研究组实施308nm 准分子激光+他克莫司治疗,比较两组的治疗总有效率、治疗前后细胞间黏附分子-1(ICAM-1)、黑素细胞刺激素(α-MSH)、白介素-17(IL-17)指标水平及不良反应发生率。

结果研究组的治疗总有效率为94.29%,高于参照组的77.14%,差异有统计学意义(P <0.05);两组治疗前的ICAM-1、α-MSH、IL-17水平比较,差异无统计学意义(P >0.05);两组治疗后的ICAM-1、IL-17水平低于治疗前,α-MSH 水平高于治疗前;治疗后研究组的ICAM-1、IL-17水平低于参照组,α-MSH 水平高于参照组,差异均有统计学意义(P <0.05)。

研究组的不良反应总发生率为11.43%,低于参照组的31.43%,差异有统计学意义(P <0.05)。

结论308nm 准分子激光+他克莫司治疗成人面部白癜风的效果显著,且不良反应少,有临床推广价值。

COMP3308/3608 Artificial IntelligenceWeek 3 Tutorial exercisesGreedy and A* algorithms. Heuristics. Local search algorithms.Exercise 1 (Homework). Greedy and A* searchConsider the tree below. Step costs are shown along the edges and heuristic values h are shown in brackets. The goal nodes are circled twice, i.e. they are C, I, E and K.( 0)Run the Greedy and A* search algorithms. Show the list of expanded nodes and the solution path found with its cost. If there are nodes with the same priority for expansion, expand the last added first.a) GreedyExpanded nodes:Path found:Path cost:b) A*Expanded nodes:Path found:Path cost:Solution:a) GreedyExpanded nodes: SBEPath found: SBEPath cost: 8Explanation:We will us the following notation: {expanded} | {fringe}Greedy search selects nodes for expansion based on the h-value. Note that:∙Selection for expansion comes before checking for goal node, and this applies for all search strategies∙We keep the nodes in the fringe ordered in increasing order, based on their desirability which is determined by the search strategy. For greedy search this means that the node with the smallest h value should be at the front of the fringe. In other words, we maintain a priority queue. So, we always select the front of the fringe, and then check if it is a goal node.For the nodes in the fringe we will also put in brackets the value used by the algorithm when selecting a node for expansion, in this case the h valueEmpty | S (expanded: empty, fringe: S)Select S for expansion (the only element in the fringe). Is S a goal node? No. Expand it, i.e. move it to expanded and add A and B to the fringe:S | A[2], B[1]Select a node for expansion from the fringe: B (as its h value is the smallest). Is B a goal node? No.Expand it. In bold we will show the selected nodes for expansion, i.e. the one that is at the front of the queue.S, B | A[2], E[0], F[2], G[1]S, B, E | A[2], F[2], G[1]b) A*Expanded nodes: SBGADIPath found: SADIPath cost: 6Explanation:empty | SS | A[6], B[4]S, B | A[6], E[8], F[9], G[5]S, B, G | A[6], E[8], F[9], K[7]S, B, G, A | E[8], F[9], K[7], C[8], D[6]S, B, G, A, D | E[8], F[9], K[7], C[8], H[20], I[6], J[14]S, B, G, A, D, I | [8], F[9], K[7], C[8], H[20], J[14]Check the graph to verify that SADI is the shortest path to a goal node!Exercise 2.Admissible heuristics – 4-queens puzzleYou are given a 4x4 chess board and the goal is to place 4 queens on the board so that no queen can capture any other. That is, only one queen can be in any row, column or diagonal of the 4x4 array. Suppose we try to solve the puzzle using the following problem space: the start node is labeled by an empty 4x4 array; the successor function creates new 4x4 arrays containing one additional legal placement of a queen anywhere in the array; the goal test is satisfied if and only if there are 4 queens in the array that are legally positioned. Note that all goal nodes are precisely 4 steps from the start node as at each step we place 1 queen and the total number of queens is 4.Explain whether each of the following is an admissible heuristic:a) h(n) = depth (n), i.e. where depth(n) is the depth of the node n in the search treeb) h(n) = 4 -queens(n), where queens(n) is the number of queens on the board in state n (i.e. the number of queens already placed)c) h(n) = 4 -queens(n) -available(n)/16, where available(n) is the number of available squares in the array that can receive a new queen in state nd) Can you solve the 4-queens puzzle?Answer:a) No, as it increases when it should decrease, leading to an overestimate. For example, at depth 4, on a goal node, it should be 0 instead of 4.b) Yes, the heuristic is admissible.∙ For nodes that are on a goal path, h(n) gives the exact number of steps to reach a goal state asthe goal nodes are precisely 4 steps from the start node, i.e. h(n)= h*(n) = 4 - queens(n).∙ Note that some nodes will not lead to a goal given the definition of the problem. For such nodes, i.e. nodes that are not on a goal path, a goal state cannot be reached and h*(n) is infinite and h(n)< h*(n).c) Yes, because it subtracts a positive number from an already admissible heuristic, i.e. decreases the heuristic value even more.d) Here is a possible solution:X X X XExercise 3. Admissibility and consistency (monotonicity)a) Does an admissible heuristic h lead to non-decreasing f values along any path? In other words, are all admissible heuristics consistent? Give an example to illustrate your answer. b) Does a non-decreasing f value along any path imply admissibility of h ?c) A* uses admissible heuristics. What happens if we use a non-admissible one? Is it still useful to use A* with a non-admissible heuristic?Answer:a) No, see the example below. h is admissible as: h(S) = 2 <= 3+1+3=7 h(n1) = 4 <= 1+3=4 h(n2) = 2<= 3However, f is not non-decreasing, it decreases atn2 as f(n2) = 6, f(n1) = 5 and f(n2)<f(n1). I.e. once we are in n1 we know that the true cost to the goal is at least 7; then we move from n1 to n2 along an arc costing 1, and this should not lead to node n2 being estimated as at least 5 units away (it is at least 6 units away as all paths through n2 are also paths through n1).=> admissibility (h) ≠>decreasing f -values (i.e. consistent heuristic) Note: non-decreasing f <=> triangle equation for hb) Yes, non-decreasing f -values along any path imply admissibility of h . What did we prove in class about consistency and non-decreasing f -values?We proved that if the heuristic is consistent, than the f-values are non-decreasing. The opposite is also true, see Ex.8.c)Not optimal anymore. But it could still find a pretty good answer in a pretty good time, depending on how good the heuristic is.Exercise 4. A*A * does not terminate until a goal node is selected for expansion from the fringe. However, a path to a goal node might be reached long before the node is selected for expansion, i.e. there may be already a goal node in the fringe. Why not terminate as soon as a goal node has been found, i.e. is in the fringe? Illustrate your answer with an example.Answer:When a goal node is placed in the fringe it means that A* has found a path to a solution but this may not be the path to the optimal solution (i.e. the shortest path to a goal).Example 1. We have seen this in several exercises, e.g. in your homework for this week (ex.1). For example, goal nodes C and E are added to the fringe before the optimal goal node I, and they are not selected for expansion.Example 2. In the Romania example, Bucharest (goal node) is added to the fringe after expanding Fagaras but it is not selected for expansion. Instead Riminicu Vilcea is expanded, then Pitesti which adds Bucharest again in the fringe (with different f-cost), and this last Bucharest is selected for expansion, and it is the optimal goal node.Example 3. See the figure below for another example. At each node the f value is indicated (g + h).1 | 2[1.5], 4[3]1, 2 | 4[3], 3[2.5]1, 2, 3 | 4[3], Goal[4] //goal node in the fringebut it will not be selected1, 2, 3, 4 | Goal[4], Goal[3]1, 2, 3, 4, Goal | Goal[4]=>The path found is 1,4,Goal, not 1,2,3,Goal The condition of stopping when a goal node is selected for expansion as opposed to stopping when a goal node is added to the fringe guarantees that we will find the shortest path to a goal (i.e. the optimal solution), provided that h is admissible.Exercise 5. Hill-climbing and beam search (adapted from Winston, Artificial Intelligence, 1993, Addison-Wesley)The graph below corresponds to travelling between cities. S is the start city and G is the goal city. The heuristic values h from each city to the goal city G are shown in brackets.a) Run the hill-climbing algorithm starting from S. Use the h-value as an evaluation function; the smaller the value, the better. Do not revisit already visited nodes. List the expanded nodes. Was the goal node found?b) Run the beam search algorithm with k=2 using the h-values as an evaluation function (the smaller, the better). Do not revisit already visited nodes. List the expanded nodes. Was the goal node found? Solution:a) Hill climbing with v = h-value: SDEFG, goal G foundb) Beam search:underlined nodes = already visited nodescircled nodes = the k best nodes selected at each level (k=2)Expanded nodes: SADBECFGSolution: SDEFG (goal found)Exercise 6. Genetic algorithms (adapted from Dunham, Data Mining, 2003, Pearson Education, ex.3.7)Given is the following initial population: {101010, 001100, 010101, 000010}. Apply the following genetic algorithm to find a better population:Fitness function: It is defined as the sum of the bit values of each individual.Selection: At each iteration select for crossover: 1) the best individual and the second best individual and 2) the best individual and the third best individual. If there are ties, resolve them randomly. Crossover: Always choose the same crossover point, between the 3rd and 4th bit.Mutation: Mutation means negating a bit. Always mutate bit 2 (the bit numbering starts from 1, from the left).Stopping condition: The average fitness for the entire population is greater than 4.Show the new population. How many iterations were needed?Solution:Initial population:ind.1 101010 f=3ind.2 001100 f=2ind.3 010101 f=3ind.4 000011 f=2iteration 1:ind.1 101|010 crossover-> 101101 mutation -> 111101 f=5ind.3 010|101 crossover-> 010010 mutation -> 000010 f=1ind.1 101|010 crossover-> 101100 mutation ->111100 f=4ind.2 001|100 crossover->001010 mutation ->011010 f=3average fitness = (5+1+4+3)/4=13/4 < 4, stopping condition is not satisfiediteration 2:ind.1 111101 f=5ind.2 000010 f=1ind.3 111100 f=4ind.4 011010 f=3ind.1 111|101 crossover->111100 mutation -> 101100 f=3ind.3 111|100 crossover->111101 mutation -> 101101 f=4ind.1 111|101 crossover->111010 mutation -> 101010 f=3ind.4 011|010 crossover->011101 mutation -> 001101 f=3average fitness = (3+4+3+3)/4=12/4 < 4, stopping condition is not satisfiediteration 3:ind.1 101100 f=3ind.2 101101 f=4ind.3 101010 f=3ind.4 001101 f=3ind.2 101|101 crossover->101100 mutation -> 111100 f=4ind.1 101|100 crossover->101101 mutation -> 111101 f=5ind.2 101|101 crossover->101010 mutation -> 111010 f=4ind.3 101|010 crossover->101101 mutation ->111101 f=5average fitness = (4+5+4+5)/4=18/4 > 4, stopping condition is satisfied3 iterations were neededExercise 7 (Advanced students only)Gaschnig’s heuristicAt the lectures we defined a relaxation of the 8-puzzle in which a tile can move from square A to square B if B is blank. The exact solution of this problem defines the Gaschnig’s heuristic. One way to compute this heuristic is the following:Let B be the location of blank in the current state.Compare the current state with the goal state:If B in the current state is occupied by a tile X in the goal state, move X to B in the current state; otherwise, move any misplaced tile to B.The value of the heuristic for a given state is the number of switches required.a) Apply the Gaschnig heuristic to solve the 8-puzzle from this initial state (B=blank):start goal2B6 123134 456758 78Bb) Explain why the Gaschnig’s heuristic is at least as accurate as h1 from the lectures (the number of misplaced tiles), i.e. it dominates h1.c) Show cases when the Gaschnig heuristic is more accurate than both h1 and h2 from the lectures. Recall that h2 is the Manhatten distance.Answer:a)s1 s2 s3 s4 s5 s6 s7start:2B6 B26 126 126 12B 123 123 123134 134 B34 43B 436 4B6 456 456758 758 758 758 758 758 7B8 78BIn yellow are the changes between 2 successive states. The number of switches needed is 7.a) The Gaschnig heuristic is exact for the relaxed version of the problem that a tile can move from A to B is B is blank. The misplaced tiles heuristic h1 is exact for the relaxed version of the problem that a tile can move from A to B. Hence, the Gaschnig heuristic is more restrictive than h1 and cannot be less than h1.c) Consider the goal state and permute 2 adjacent tiles, e.g. tiles 1 and 2:21345678BBoth heuristics h1 and h2 return 2 but the Gaschnig’s heuristic returns 3:h1=2 (2 misplaced tiles: 1 and 2)h2=2 (Manhatten distance, values of 1 for tiles 1 and 2 and 0 for the remaining tiles)Gaschnig’s heuristic =3 (3 swaps are needed to get to the goal state):B13 1B3 123456 456 456782 782 78BGaschnig dominates h1, h2 dominates h1 but we don’t know the relationship between Gaschnig and h2. Exercise 8 (Advanced students only)A* algorithmProof that if the f-values never decrease along any path to a goal, the heuristic is consistent. Hint: see the proof of the opposite (if the heuristic is consistent, than the f-value never decreases) from the lecture notes.Proof: Not provided as it is very similar to the proof of the opposite discussed at the lectures.。

EDS-308Series8-port unmanaged Ethernet switchesFeatures and Benefits•Relay output warning for power failure and port break alarm •Broadcast storm protection•-40to 75°C operating temperature range (-T models)CertificationsIntroductionThe EDS-308Ethernet switches provide an economical solution for your industrial Ethernet connections.These 8-port switches come with a built-in relay warning function that alerts network engineers when power failures or port breaks occur.In addition,the switches are designed for harsh industrial environments,such as the hazardous locations defined by the Class 1Div.2and ATEX Zone 2standards.The switches comply with FCC,UL,and CE standards and support either a standard operating temperature range of -10to 60°C or a wideoperating temperature range of -40to 75°C.All switches in the series undergo a 100%burn-in test to ensure that they fulfill the special needs of industrial automation control applications.The EDS-308switches can be installed easily on a DIN rail or in a distribution box.SpecificationsInput/Output InterfaceAlarm Contact Channels1relay output with current carrying capacity of 1A @24VDCEthernet Interface10/100BaseT(X)Ports

Model 308A, 306, 304Vishay BLHDocument Number: Summing Units, Extension Boxes, & CablesFEATURES•Summing units—analog summing of up to eight (8) transducers (no trim pots that cause calibration shifts)•Extension boxes—extend transducer cables without performance degradation•System cables—custom manufactured for high performance over long distances and ranges of environmental conditionsDESCRIPTIONModel 308A and 306 Summing Units pro-vide a multi-cell interface for load cell sig-nal conditioning instrumentation. Versions available are capable of (analog) summing up to 8 individual transducer signals. A wide range of enclosure options are availa-ble for washdown, corrosive, and electrical hazard applications.Operationally, these units perform the mul-tiple tasks of distributing excitation current,summing transducer output signals, and protecting wiring and connections. A unique circuit design in the 308A unit mini-mizes the effects of system unbalance and electrical leakage. This added protection is beneficial when equipment is located in a harsh, corrosive atmosphere. Model 306units are compatible with Plug-n-Weigh in-strument calibration procedures for faster system start-up.304 Extension Boxes are used whenever transducer cables are not long enough to reach the summing unit or system instru-mentation. The internal terminal block or connection provides for either a four wire or six wire (remote sensing) hookup. A range of metallic enclosures are available for washdown, corrosive, and electrical haz-ard applications.Vishay BLH offers a range of system ca-bles for connection between the summing unit, junction box, and system instrumenta-tion. These custom cables are designed for use over long distances without signal losses, temperature effects, undue EMI/RFI, or environmental deterioration.APPLICATIONS•Load cell summing •Hazardous location installations•Cable extension boxes •CablesCONFIGURATION micro-measurements@Document Number: 12187Model 308A, 306, 304Vishay BLHSumming Units, Extension Boxes, & CablesMODEL 308A SUMMING JUNCTION BOXMODEL 308A EXPLOSION-PROOF OPTION• 4 or 8 transducer capability• Unbalance/leakage compensation • Standard NEMA 4 enclosure• Optional NEMA 4X or explosion-proof enclosuresDimensions shown in inchesFor Class II, Div. 1,Group E, F, GNOTE: Load cells installed in Div. 1 hazardous locations must be protected with intrinsic safety barriers.Explosion-proof enclosures are not required in intrinsically safe systems.Dimensions shown in mm (in.)Model 308A, 306, 304Vishay BLHDocument Number: 12187micro-measurements@Summing Units, Extension Boxes, & CablesMODEL 306 SUMMING JUNCTION BOXMODEL 304 EXTENSION BOXModel 304 Outline (NEMA 4)Model 304 EX Outline• 4 transducer capability standard;multiple units can be connected together for 8 cell systems • Standard NEMA 4X stainless steel enclosureDimensions shown in inches• Extend cable length to reach summing box • Supports applications requiring remote sensing • Explosion-proof enclosure option Dimensions shown in mm (in.)
