疾病改变历史,疾病改变人类 The history of mankind is the history of its diseases – Folke Henschen ( ) Disease changes the human civilization and human history Disease changes human itself genetically
3
疾病对人类社会的影响 Impact of disease on the human society
Fear, anxiety and panic results in social instability Population dramatically decreased, including the elite groups of society Political turmoil, economic recession and social development stagnated or went down Impact on the outcome of wars Enhance the development of public health and medical sciences
4
The impact on population of disease 疾病对人类社会的影响
From Zhou and Qin ( BC) to Ming and Qing Dynasty ( ) the Chinese population fluctuated from 10 to 60 million, it did not reach 100 million till Qianlong Reign ( )of Qing Dynasty Apart from war and famine the most influential factors for population is the disease epidemics
5
Trends of World Population
billion

疾病 对文明进程的影响 Impact of disease on progress of civilization
The golden ages of Greece ended by plaques in 430 BC Spartans (斯巴达人) ravaged the surrounding countryside of Athens, an epidemic (smallpox?)struck the crowded urban populace , killed thousands, including General Pericles (伯里克利 429 BC). Ended the Greek golden age (338 BC Philip II of Macedonia, 146 BC fell in Roman) Pericles (495?-429) BC

疾病 对文明进程的影响 Impact of disease on progress of civilization
The decline and fall of Rome Empire – impact of plagues 瘟疫导致罗马帝国的衰落 AD “Plaque of Galen” (smallpox?) two Roman emperors — Lucius Verus (169BC) and Marcus Aurelius (180BC) died from the epidemic, total death toll reached to 4-5 million AD second epidemics contributed to final fall of Roman Empire in 476 AD (Falciparum malaria) Marcus Aurelius Meditation

疾病 对文明进程的影响 Impact of disease on progress of civilization
Since 16 century western colonists started entering the Africa, but the fatal infectious disease stopped them (white people’s tomb”) The discovery of quinine let Europeans managed to colonize Africa “Tropical disease”
9
Voyage of Columbus Since 1492 Columbus discovered the new continent, European colonists brought disasters to native Americans Columbus voyage 1492
10
疾病 对文明进程的影响-美洲文明 Ancient American civilization
Three civilizations Maya (2500BC-8th century) Aztec Inca
11
Impact of Disease on civilization
Spanish General Cortes conquered Aztec in (300+ smallpox vs 15 million), The capital Tenochtitlan fell, population of Aztec dropped to 1million Spanish conquest Pizarro colonized Inca in 1553 resulting dramatically reduced Incan population (200 vs 50,000)
12
Impact of Disease on Human Civilization
1518 slave trade started,brought infectious diseases previously not existing in America (malaria, yellow fever) and insects, resulting further decrease of native population
13
Impact of Disease on Human Civilization
16th century epidemics in America smallpox measles typhus influenza By the end of 16th century the number of native Americans reduced by 90-95%
14
Disease changed human itself-Evolution of immune system
15
先天性免疫 Innate Immunity Toll样受体 Toll-like Receptor, TLR 获得性免疫 Adaptive Immunity 树突状细胞 Dendritic Cell, DC
16
Disease changed human itself - Impact on human genes
A T Gl Val Change of configuration 镰状红细胞贫血 Sickle cell anemia HbAHbA HbAHbS HbSHbS A A AS SS Homozygote Heterozygote
17
Disease changed human itself - Impact on human genes
Distribution of Falciparum malaria Distribution of sickle cell gene carrier
18
Disease changed human itself - Impact on human genes
In sub-Saharan Africa the incidence of sickle cell anamia as high as 1/400, Heterozygote--carriers of a single sickle cell allele are 8-10% The sickle cells have protection from malaria (plasmodium can not parasite), it may be the results of evolution (mutant events back to ,000 years ago)
19
AIDS virus And CD4 T-cells
20
Two receptors are necessary for HIV to enter the CD4 T cell :CD4 and CCR5
21
CCR5 and HIV infection In 2008, German doctors reported that an HIV-infected leukemia patient had received a bone marrow transplant from a donor who is homozygous for the CCR5-Δ32 trait. After 600 days, the patient was healthy and had undetectable levels of HIV in the blood and in examined brain and rectal tissues
22
疾病改变人类-CCR5Δ32 T-cell membrane receptor CCR5 variant CCR5-Δ32 was found in people with natural immune to HIV Frequency of CCR5-Δ32 varies: Not in African or Asian origin North European 14% Mediterraneans 2% Average 10% Europeans with one allele, 1% with two alleles
23
Origin of CCR5 mutation? Eyam- the Plague village in England
September 1665 Black death outbreak in the village, the villagers decided self-isolated from others 260 out of 350 villagers dies in 1 year From death records since 1630, the descendants of survivors were traced, 14% of them carry the gene mutation ofCCR5-Δ32 Eyam- the Plague village in England
24
Origin of CCR5 mutation? Which disease facilitated the natural selection? Plague? Smallpox? Scott and Duncan: mathematical modeling study reveals the CCR5-Δ32 may appear ago It may be related to a feverish viral disease similar to Ebola hemorrhagic fever
25
Disease and the outcome of war (For want of a nail – rhyme)
For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the battle was lost. For want of a battle the kingdom was lost. And all for the want of a horseshoe nail. Benjamin Franklin ( ) 因缺少一颗钉子而损失一匹战马
26
Napoleon’s hemorrhoids and defeat at Waterloo
Napoleon Bonaparte ( ),was finally defeated by Duke of Wellington at Waterloo on June , because painful thrombosis hemorrhoids prevented him personally surveying the battle fields on the horse back. (anecdotage) Exiled to Saint Helena
27
1812 Napoleon’s Invasion of Russia
June 1812 Napoleon mobilized 500,000 French and allied troopers to invade Russia, retreated on December with less than 10,000 men remained. Who defeated Napoleon? Marshall Kutuzov? Cold winter in Moscow?
28
Who defeated Napoleon? Endemic Typhus
Fatal epidemics of typhus outbroke among French soldiers, resulting severe depletion of troopers, when Napoleon entered Moscow only 90,000 men left. 斑疹伤寒 Typhus (Trench Fever or Jail Fever) Caused by Rickettsia transmitted by louse or flea. Rickettsia Prowazekii
29
Russian Revolution and Fall of Romanov Reign

Who overthrew the Romanov Regime?
Vladimir Lenin Queen Victoria
32
血友病 Hemophilia Hemophilia is a rare, inherited bleeding disorder in which the blood doesn’t clot normally Type A: 80-85%, deficiency of clotting factor VIII Type B: 15-20%, deficiency of clotting factor IX
33
Sex chromosome-linked inheritance (recessive allele)
34
A pedigree European Royal Family
35
Victoria and Royal Family
36
Tsar Nicholas II married Alexandra,gave birth of Alexis,the misfortune of Romanovs started: Tsar and Tsarina were preoccupied with the health of their son, the affairs of state deteriorated, culminating in the Russian revolution.
