Dry eye is one of the most frequently ocular surface diseases. Recent researches found that many reasons caused decrease of ocular surface damage and the quality of tears , such as the change of ocular surface, immuno-inflammatory responses, apoptosis and the reduction of sex hormone. It is reported that the decline of ovarian function and hormone level in postmenopausal women which leads to abnormal structure and function of tear film is more likely to develop dry eye. In this paper, the ocular surface, pathogenesis and progresses of treatment on postmenopausal women with dry eye are reviewed.

Objective:To investigate the regulatory effect of dissociative intracytoplasmic domain of leukemia inhibitory factor receptor ? (LIFR?) subunit on the growth of HL-60 cells and the related signal transduction mechanism. Methods: The constructed recombinant plasmids pcDNA3.0-190CT2+3 and cDNA3.0-190CT3 were identified and transfected into HL-60 cells with liposome FuGene-6. Then the cells were cultured in a medium containing G-418 and the positive clones were selected. Immunohistochemical method and Western blotting were used to detect the expression of the target protein in HL-60 cells and the growth curve of the cells was plotted. The expression of proliferating cell nuclear antigen (PCNA) and the phosphorylation levels of signal transducer and activator of transcription 3 (Stat3) were assayed by Western blotting. Results: Western blotting detected the band of target protein and the cell line stably expressing the target protein was obtained. Compared with that of the wild type group, the cell sizes in 190CT2+3 and 190CT3 group were enlarged. The ratio of leaf cell number to the total cell number increased and the cell proliferation was slowed down. We also found that the expression of PCNA was decreased and the phosphorylation level of STAT3 was increased. Conclusion: The dissociative intracytoplasmic domain of LIFR? subunit can accelerate the differentiation of HL-60 cells, inhibit the proliferation of HL-60 cells, and activate signal molecule STAT3.

Objective To compare the inhibitory effects of Butorphanol and Dezocine on Etomidate-induced myoclo?nus. Methods A total of 150 patients with ASA physical statusⅠorⅡ, aged 40-65 yr, with body mass index (BMI) of 20-25 kg/m2, scheduled for elective operations under general anesthesia, were included in this study. Patients were randomly al?located into three groups (A, B and C) with 50 patients in each group. Group A was given intravenous Butorphanol 15 μg/kg for 30 s, group B was given Dezocine 0.1 mg/kg and group C was given equal volume of saline. After 2 min, etomidate 0.3 mg/kg was administrated to three groups. The occurrence and severity of myoclonus were recorded for 2 min after administration of Etomidate. The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2) and Bispectral index (BIS) were recorded at the time points before induction (T0), 2 min after the experimental drug treatment (T1), and 2 min after Etomi?date treatment (T2). At the same time, the concentration of serum potassium was determined at T0 and 5 min after endotrache?al intubation (T3) respectively. Results The positive incidences of myoclonus were 12%in group A, 22%in group B and 74%in group C, respectively. Compared with group C, the positive incidence rates of myoclonus and myoclonus scales were significantly lower in group A and group B (P<0.05), but no significant difference between group A and group B (P>0.05). Compared with T0, there was no significant difference in the potassium concentration between patients without myoclonus (grade 0) and patients with myoclonus (grade 1 and grade 2) at T3 (P>0.05). There was a significant increase in potassium concentration in patients with grade 3 (P<0.05). There were no significant differences in MAP, HR, SpO2 and BIS values at T0, T1 and T2 between three groups of patients (P>0.05). Conclusion Pre-treatment of Butorphanol (15μg/kg) or Dezocine (0.1 mg/kg) can reduce the Etomidate-induced myoclonus. At the same time, both therapies show no different effects on cir?culation and respiration system.

Objective To compare butorphanol or midazolam alone and combination of the two drugs in preventing etomidate-induced myoclonus during anesthesia induction.Methods One hundred sixty patients, aged 40-64 yr, with body mass index of 20-25 kg/m2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective operations under general anesthesia, were randomly allocated into 4 groups with 40 patients in each group: control group (group C), butorphanol group (group B) , midazolam group (group M) , and butorphanol combined with midazolam group (group BM).Before induction of anesthesia, butorphanol 15.0 μg/kg, midazolam 50 μg/kg, and butorphanol 7.5 μg/kg combined with midazolam 25 μg/kg were injected intravenously over 30 s in B, M and BM groups, respectively.The equal volume of normal saline was given in group C.And 2 min later, etomidate 0.3 mg/kg was injected intravenously over 1 min.The occurrence of myoclonus was recorded within 2 min after administration of etomidate, and the severity of myoclonus was assessed.Results Compared with group C, the incidence and severity of myoclonus were significantly decreased in B, M and BM groups (P＜0.05).Compared with B and M groups, the incidence and severity of myoclonus were significantly decreased in group BM (P＜0.05).There was no significant difference in the incidence and severity of myoclonus between group B and group M (P ＞ 0.05).Conclusion Butorphanol or midazolam alone produces similar efficacy in preventing etomidate-induced myoclonus during anesthesia induction, and the combination of the two drugs provides better efficacy than either alone in the patients.

Objective To confirm subject headings which are prepared to be added, deleted and modified in the class of traditional Chinese medicine and related disciplines (TG class) for the new edition of Chinese Traditional Medicine and Materia Medica Subject Headings (CTMMeSH). Methods Compiling principle, word frequency statistics and database retrieval results were considered. Other references, such as MeSH, were also used to help choose subject headings of TG class. Results In TG class, 35 subject headings were planned to be added, such as “medicine, traditional Korean”and“TCM constitution”;35 subject headings were planned to be deleted, such as“medicine, eastern tradition”and“meridians”;19 subject headings were planned to be modified, such as “four-constitution medicine” and “Minority Medicine”. The subject headings of “Minority Medicine”were unified to harmonize the problems of“TCM pharmacy”with other classes of subject terms. Conclusion Subject headings of TG class are chosen based on word frequency statistics. The word form are unified refer to regulation, teaching materials and documents, and should coordinate with subject headings of other classes.
