AIM： To describe the clinical features and microstructural characteristics assessed by in vivo confocal microscopy（IVCM） in patients with ocular cicatricial pemphigoid（OCP）.· METHODS： A descriptive, uncontrolled case series study. Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence（DIF） biopsies and indirect immunofluorescence（IIF） were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response.·RESULTS： A total of 12 consecutive OCP patients（7male, 5 female; mean age 60.42 ±10.39y） were *** patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95 ±2.85y（range： 5mo to 10y）. The Foster classification varied from stage I to IV and 20 eyes（83%） were within or greater than Foster stage Ⅲ on presentation. Two of the 12patients（17%） demonstrated positive DIF; 3 of the 12（25%） patients reported positive IIF. The mean duration of the follow-up period was 20.17 ±11.88mo（range： 6 to48mo）. IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal stromal cell activation and dendritic cell infiltration presented asocular surface inflammation, ocular surface keratinization along with the destroyed Vogt palisades was noted in eyes with potential limbal stem cell deficiency. After treatment, remission of ocular surface inflammation was achieved in all the patients, 18 eyes（75%） remained stable, 6 eyes（25%） had recurrent conjunctivitis and cicatrization in 2 eyes（8%） was progressing.· CONCLUSION： As an autoimmune disease, OCP manifests as variable degrees of clinical and laboratory abnormalities with both local and systemic immunosuppressive treatment playing important roles in disease therap

Early generation stability of a japonica rice variety, 84-15, was retested by using the allelic differences of two qualitative traits, i.e., glume tip color and waxy endosperm. Results showed that both glurne tip color and waxy endosperm segregated in progenies of single F1 plants derived from two crosses of 84-15/Zi 18 （purple color） and 84-15/Dahuaxiangnuo （waxy）. The results denied the conclusion obtained in previous studies that 84-15 had a characteristic of early generation stability. Moreover, it was found that using the coefficient of variation as an indicator of early generation stability was unreasonable by analyzing plant height as an example. Importance of avoiding systematic error in research works was also discussed.
