·AIM: To investigate the effect of vitamin A on the conjunctival goblet cells of rat after corneal transplantation.·METHODS: Rat graft rejection models of corneal transplantation were established. SD rats were receptor and Wistar rats were donors. After corneal allografts were performed, 48 SD rats were randomly divided into three groups, 16 rats in each group. Group A was blank control group; group B was treated by oculotect gel (containing vitamin A); group C was treated by 1g/L dexamethasone eyedrops. Besides, group D was normal unoperated eyes.Slit-lamp microscope was employed to record and compare rejection index (RI) of corneal transplantation. Through HE,PAS staining of conjunctival histological sections and image analysis system, the number and morphology of conjunctival goblet cells were observed and analyzed between operation group and normal group.·RESULTS: The HE, PAS staining detection showed that the number of conjunctival goblet cells in oculotect gel group,1g/L dexamethasone eyedrops group and control group is lower than that in normal group after surgery (P＜0.01). The number of conjunctival goblet cells in oculotect gel group and 1g/L dexamethasone eyedrops group is higher than that in control group (P＜0.05). The number of conjunctival goblet cells in 1g/L dexamethasone eyedrops group is higher than that in oculotect gel group (P＜0.05).·CONCLUSION: The results indicate that vitamin A may inhibit the decrease of conjunctival goblet cells after corneal allograft rejection in rats.

Abstract: Objective　To analyze the impact of the flood disaster on the distribution of Oncomelania snails in 2020 in Wuhu City, to provide scientific basis for formulating the "14th Five-Year Plan" for schistosomiasis control and precise prevention and control measures in Wuhu City. Methods　Systematic sampling combined with environmental spot check was used to investigate the distribution of snails in the historical snail's environment, existing snail's environment and suspected snail's environment in Wuhu City. The collected snails were crushed and examined by microscope to understand the death and life of snails and the infection of Schistosoma japonicum, and the density of live snails and other indicators were counted. Results　The historical area of snails was 14 475.24 hm2 in Wuhu City, and the existing area of snails was 4 588.72 hm2, including 4 210.32 hm2 for lake type and 378.40 hm2 for hill type snails. The average occurrence rate of live snails was 14.59%, and the average density of live snails was 0.50 snails/0.1 m2 in Wuhu City. There were 2 745 snail breeding environments, of which 491 were lake type and 2 254 are hill type, accounting for 17.89% and 82.11% respectively. The existing snail area was mainly distributed in the beaches and ditches, accounting for 92.51% and 6.29% of the existing snail area respectively. Some snails were distributed in ponds, paddy fields and other environments. Among all the historical snail habitats, the majority were class Ⅱ and class Ⅲ environments (which still have the basic conditions for snail breeding at present), with a total of 1 739 sites (blocks), accounting for 63.35% of the total environment. No schistosomiasis infected snails have been found, and the newly discovered and recovered snails cover an area of 268.21 hm2 in Wuhu City. Conclusions　The distribution of snails is extensive in Wuhu City, and snails are mostly distributed in beaches, which are vulnerable to the impact of flood disasters. The spread of Oncomelania snails is found in 30 marshlands in 3 counties in this survey. It is necessary to continue to strengthen snail monitoring after disasters, and take class Ⅱ and class Ⅲ environments as key areas for snail monitoring, so as to find, identify and evaluate the risk of schistosomiasis transmission as soon as possible, to avoid or reduce the impact of flood disasters on the process of schistosomiasis control, and promote the process of schistosomiasis elimination.

Objective To investigate the relationship between pancreatic cancer and diabetes mellitus (DM). Methods Two hundreds and twenty patients with pancreatic cancer and 300 controls, who suffered from non-digestive tract, non-neoplastic or non-hormone-related disorders, were enrolled from 1997 to 2007. The incidence of diabetes between the two groups and the relationship between pancreatic cancer and diabetes were compared, pancreatic cancer patients with DM were compared with patients without DM for their gender, age, location and differentiate degree of the cancer. Results The incidence of DM in the two groups were 33.1% and 9.67%, respectively, and the difference was significant (P < 0.05). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2 years or for more than 10 years were 25.91% (57/73) and 3.18% (7/73), which were significant higher than those in the control group 6.0% (18/29) and 0.67% (2/29)) (χ2=46.15, P<0.01, 0R=6.07; χ2 =4.72, P<0.01, OR=4.90). In the pancreatic cancer group, the proportion of patients with DM diagnosed within 2～5 years or 5～10 years was not significant different when compared with that of the control group, and there was no significant difference in terms of gender, age and cancer location between the pancreatic cancer patients with DM and without DM. The majority of pancreatic cancer patients with DM had corpora mammillaria or well differentiated adenocarcinoma, and the majority of pancreatic cancer patients without DM had differentiated adenocarcinoma. Conclusions DM was closely related with pancreatic cancer and DM may be one of the presentations of pancreatic cancer, as well as a possible risk factor for the tumor.

BACKGROUND:Schizophrenia is a kind of psychosis which pathogenesis is unknown yet, and its pathogenesis is a key study theme all over the world. Recently it is concerned in genetic study, particularly in the molecular genetics. Among them, it shows a good prospect in researching the candidate functional gene. OBJECTIVE:To analyze the association between the T102C polymorphism of serotonin 2A (5-HT2A) receptor and schizophrenia. DESIGN: A diagnosis-based ease observation and association analysis. SETTING: Second Affiliated Hospital, Xinxiang Medical College and the 13 Branch of General Hospital of Zhongyuan Oil Field. PARTICIPANTS: In the patient group, there were 56 cases of schizophrenie probands, who were hospitalized in the Second Affiliated Hospital of Xinxiang Medical College from August 2003 to April 2004, and their healthy parents (n=112) were also enrolled as the parents group. METHODS:The nuclear family consisted of 56 probands, who met the diagnostic criteria of the third edition of Chinese Classification and diagnostic criteria of Mental Disorders (CCMD-3), and their parents were detected with polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP), the genotype and the T102C polymorphism of schizophrenic 5-HT2A receptor were detected with transmission disequilibrium test (TDT). MAIN OUTCOME MEASURES:The results of allele and genotypic frequency, and the goodness-of-fit for Hardy-Weinberg equilibrium of 5- HT2A receptor, as well as the TDT analytical results of 5-HT2A receptor gene, were observed. RESULTS:All the 56 patients and the 112 parents were involved in the analysis of results. ①No significant differences were found between the patient group and parents group in the genotypic frequencies (χ2 =4.423, P=0.110) and allele distribution (χ2=1.147, P=0.563), and there was a good goodness-of-fit for Hardy-Weinberg equilibrium. ② In the 56 families, the transmission disequilibrium of 39 nuclear families with paternal or maternal genotype of heterozygote detected by TDT showed no association between schizophrenia and 5-TH2A receptor gene (χ2=2.703, P=-0.10).CONCLUSION: There is no association between the 5-TH2A receptor gene T102C and schizophrenia in Chinese Han population.
