Abstract
Retinitis pigmentosa (RP) is one of the most common forms of hereditary neurodegeneration. It is caused by one or more of at least 3,100 mutations in over 80 genes that are primarily expressed in rod photoreceptors. In RP, the primary rod-death phase is followed by cone death, regardless of the underlying gene mutation that drove the initial rod degeneration. Dampening the oxidation of glycolytic end products in rod mitochondria enhances cone survival in divergent etiological disease models independent of the underlying rod-specific gene mutations. Therapeutic editing of the prolyl hydroxylase domain-containing protein gene (PHD2, also known as Egln1) in rod photoreceptors led to the sustained survival of both diseased rods and cones in both preclinical autosomal-recessive and dominant RP models. Adeno-associated virus-mediated CRISPR-based therapeutic reprogramming of the aerobic glycolysis node may serve as a gene-agnostic treatment for patients with various forms of RP.

Abstract
OBJECTIVE To observe the effect of Erigeron breviscapus (Vant) Hand Mazz (HEr) in impeding oral leukoplakia carcinogenesis, and to seek effective Chinese herb medicine that can impede precarcinoma of oral mucosas. METHODS 132 golden hamsters were randomly divided into model group (60 animals), HEr group (60 animals), and control group 12 animals. Salley's leukoplakia carcinogenesis model of golden hamster cheek pouch was used in this study. HEr was injected into the stomach to impede evolution of carcinogenesis. Pathological specimens were observed via naked eye and light microscope between model group and HEr group. Results were compared. RESULTS Observation via naked-eye showed that leukoplakia rate of HEr group (18.2%) was lower than that of model group (27.3%). Observation via light microscope showed that carcinogenesis rate descended one fold and displasia rate descended 0.4 fold in HEr group. CONCLUSION HEr has exact effect in impeding leukoplakia carcinogenesis.

Abstract
All intelligence tests are for children old than two and a half years; we still do not have an intelligence assessment tool for children younger than this age. If we knew the relationship between the intelligence quotient and developmental indices as measured by the Bayley Scale of Infant Development (BSID), it would allow us to assess the mental development of young children earlier and to start adequate management sooner. The present study was designed to meet this need. We collected our data from a six-year follow-up study of Yu-Cheng (oil disease) children born to mothers who had a history of ingesting rice cooking oil contaminated with polychlorinated biphenyls (PCBs) in 1978-1979 and their matched controls. We analyzed the correlations between the developmental indices of the BSID assessed on 44 pairs of Yu-Cheng children and their controls in 1985 and the Stanford-Binet Intelligence Quotients (S-B IQ) assessed on the same group of children in 1987 and 1988. For the matched controls, we found practically no significant correlation between the BSID developmental indices and the S-B IQ (r = .04-.20, p = .23-.82). In the Yu-Cheng children, that is at-risk group, there was a significant correlation between the Mental Developmental Index (MDI) of BSID and the S-B IQ (r = .33-.43, p = .01-.05) and between the Psychomotor Developmental Index (PDI) of BSID and the S-B IQ (r = .31-.47, p = .00-.07). We conclude that the development indices of BSID has a better predictive power on the intelligence among the at-risk group such as Yu-Cheng children.

Abstract
A case-control study of oral cancer was conducted in Beijing, People's Republic of China. The study was hospital-based and controls were hospital in-patients matched to the cases by age and gender. A total of 404 case/control pairs were interviewed. This paper provides data regarding oral conditions as risk factors for oral cancer, with every patient having an intact mouth examined (pre-operation among cases) using a standard examination completed by trained oral physicians. After adjustment for tobacco smoking and alcohol consumption, poor dentition--as reflected by missing teeth--emerged as a strong risk factor for oral cancer: the odds ratio (OR) for those who had lost 15-32 teeth compared to those who had lost none was 5.3 for men and 7.3 for women and the trend was significant (P less than 0.01) in both genders. Those who reported that they did not brush their teeth also had an elevated risk (OR = 6.9 for men, 2.5 for women). Compared to those who had no oral mucosal lesions on examination (OR = 1.0), persons with leukoplakia and lichen planus also showed an elevated risk of oral cancer among men and women. Denture wearing per se did not increase oral cancer risk (OR = 1.0 for men, 1.3 for women) although wearing metal dentures augmented risk (OR = 5.5 for men). These findings indicate that oral hygiene and several oral conditions are risk factors for oral cancer, independently of the known risks associated with smoking and drinking.

Abstract
A case-control study of oral cancer was conducted in Beijing, People's Republic of China (PRC). The study was hospital-based and controls were hospital in-patients matched for age and gender with the cases. The response rates for cases and controls were 100 percent and 404 case/control pairs were interviewed. Tobacco smoking and alcohol consumption emerged as independent risk factors for oral cancer. For tobacco smoking, the association was considerably stronger for smokers of pipes than for smokers of cigarettes. For all kinds of tobacco, expressed as cigarette equivalents, the odds ratio (OR) for total pack-years smoked, among males, rose from 1.0 in never-smokers to 3.7 (95 percent confidence interval, 1.8-7.4) in the highest quintile of exposure. Similar results were found for females. The association with tobacco consumption was strong for squamous cell carcinoma but there was no trend in risk associated with tobacco for adenocarcinomas and other histologic types. So few women reported consuming alcohol that this variable could be examined only in males. Risk in the highest category of total lifetime intake of alcohol relative to that in lifetime abstainers was 2.3 (1.1-4.8) with a significant trend in risk with increasing dose (P less than 0.002). The combined effects of tobacco and alcohol appear to be approximately multiplicative in males. The attributable risk of oral cancer for tobacco among tobacco smokers was estimated as 34 percent (45 percent among males and 21 percent among females); for alcohol consumption in males the estimate was 23 percent.
