Psychological states and needs among post-allogeneic hematopoietic stem cell transplantation survivors.

OBJECTIVES: To analyze psychological states and needs of patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Questionnaires were sent to 101 allo-HSCT survivors and 96 questionnaires were returned. The questionnaire covered several categories: (1) demographics and general information, (2) physical conditions, (3) psychologic status and sleep quality, (4) survivor's comments on transplantation, (5) demands and needs, (6) preferred forms and channels of information. RESULTS: Depression and poor sleep quality were major concerns troubling allo-HSCT survivors. A notable discrepancy exists between clinically diagnosed depression (4.2%) and self- reported depression based on BDI-13 (55.2%). Young adults (18-49 years old), chronic graft-versus-host disease, the ECOG performance score of 2-4, surviving within 5 years since HSCT, no or low dose of ATG used and being single were significantly associated with self-reported depression. Based on the PSQI score, 75% of survivors experienced varying degrees of sleep quality impairment. Young adults, chronic GVHD and the ECOG score of 2-4 were significantly associated with worse sleep quality. The majority of patients reported unmet needs on physical and psychosocial aspects. Nutrition information was the most important topic, followed by disease treatments and fatigue. Differences in informational needs were found in the survivors according to age, time since HSCT and gender. WeChat public account and WeChat applet, mobile interactive platform and one-to-one conversation were the favorite channel for information. CONCLUSIONS: Clinicians should establish more appropriate survivorship care plans focusing on survivors' psychologic states, demands and needs.

Comparative study of the clinical observation on traumatic perforation of tympanic membrane / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the clinical treatment effects of sea buckthorn oil for in different size traumatic perforation of tympanic membrane in different size.@*METHOD@#Prospective, randomized study of 199 outpatients with traumatic perforation of tympanic membrane who were enrolled between December 2012 and December 2014 after informed consent. The patients were divided into treatment group (101 cases) and control group (98 cases). According to the size of the perforations, patients in each group were divided into large perforation group, middle perforation groups and small perforation group. The cases in large perforation group, middle perforation groups and small perforation group were 36, 34, 31 in treatment group and 35, 33, 30 in control group. The patients in treatment group were treated with sea buckthorn oil once a week, while the patient in control group were self-healing and checked once a week. All the patients were followed-up in two months. The healing rate of two groups was applied for the evaluation indicator of clinical effect. We compared the healing rate, average healing time and phological change of tympanic membrane of patients at the first and second month.@*RESULT@#The total healing ratio of patients in treatment group is 62.4% and 79.2% compared with 29.6% and 57.1% in control group at the first and second month (P 0.05). The average healing time of large, middle and small perforation group at the second month are significantly shorter than the control group.@*CONCLUSION@#It is better to apply observation method and let it self-healed for small traumatic tympanic membrane perforation according to its higher healing ratio. While, it is better to apply sea buckthorn oil method for middle and large traumatic tympanic membrane perforation according to its lower healing ratios. Sea buckthorn oil treatment is benefitial for increasing the ratio of perforation healing, shorten the healing time, resumpting of the middle ear function earlier, helping most of the patients to avoid operation and the reduce medical expense. Therefore, it is valuable to promote the method in clinical treatment.

Expression level and significance of IL-17 and IL-23 in serum and nasal secretion of patients with allergic rhinitis and non-allergrie rhinitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the effect of IL-17 and IL-23 in the pathogenesis of allergic rhinitis(AR) and non. allergic rhinitis(NAR).@*METHOD@#Selected 156 cases of patients with allergic rhinitis (AR group) and 59 cases of patients with non-allergic rhinitis (NAR group), 60 cases of healthy people (control group). All cases in AR group and NAR groups were evaluated by a visual analog scale (VAS) score of nasal symptoms. Collected peripheral blood and nasal secretions in all cases and then detected IL-17 and IL-23 expression levels.@*RESULT@#There was no significant difference in VAS score of AR group and NAR group (P>0. 05). IL-17 and IL-23 levels of serum and nasal secretions in AR group and NAR group were both higher than control group, with a highly significant difference (P <0. 05). The research showed a clear correlation between expression of IL-17 and IL-23 both in serum and nasal secretions of AR group and NAR(P<0. 05).@*CONCLUSION@#IL-17 and IL-23 may be important cytokines and IL-23/IL-17 pathway may play a significant role in the pathogenesis of allergic rhinitis and non-allergic rhinitis.

Role of ERKⅠ/Ⅱ in the induction and maintenance of the spinal LTP / 中国病理生理杂志

AIM: The role of external-signal regulated kinaseⅠ/Ⅱ(ERKⅠ/Ⅱ) in the induction and maintenance of spinal long-term potentiation(LTP) is evaluated.METHODS: The C-fiber evoked field potentials were recorded at the superficial layers of spinal dorsal horn at the lumbar enlargement.RESULTS:(1) PD98059(100 ?mol/L) or SL327(200(?mol/L)),a selective MEK inhibitor,completely blocked LTP induction when applied at 30 min prior to tetanic stimulation.(2) PD98059 or SL327 reversed spinal LTP in a time-dependent manner.At 15 min after LTP induction,PD98059(100 ?mol/L) or SL327(200 ?mol/L) reversed LTP completely,and at 30 min after LTP induction,the inhibitory rate of spinal LTP inhibited by PD98059 or SL327 was 62.5% and 75.0%, respectively.At 1 h after LTP induction,however,the same concentration of PD98059 or SL327 did not affect the spinal LTP.CONCLUSION: Activation of ERKⅠ/Ⅱ in spinal dorsal horn may be crucial for the induction and the early-phase maintenance of LTP of C-fiber evoked field potentials.

Protein kinase C is involved in the induction and early- phase maintenance of long-term potentiation of C-fiber evoked field potentials in spinal dorsal horn of adult rats / 中国病理生理杂志

AIM: The role of protein kinase C (PKC) in th e induction and maintenance of spinal long-term potentiation (LTP) was evaluated . METHODS: The C-fiber evoked field potentials were recorded at t he superficial layers of spinal dorsal horn at the lumbar enlargement. RESULTS: (i) Chelerythrine (200 ?mol/L) or G 6983 (100 ? mol/L), a selective PKC inhibitor, completely blocked LTP induction. (ii) Chel eryt hrine or G 6983 reversed spinal LTP in a time-dependent manner. 15 min after L TP induction, chelerythrine (200 ?mol/L) and G 6983 (100 ?mol/L) depre ssed LTP to baseline in all tested rats. The same concentration of chelerythrine and G 6983, applied at 3 h after LTP induction, did not affect LTP. CONCLUSION: PKC in spinal dorsal horn may be crucial for the ind uction and the early-phase maintenance of LTP of C-fiber evoked field potentials .

PKA is required in the induction and early-phase maintenance of LTP of C-fiber evoked field potentials in spinal dorsal horn of adult rats / 中国病理生理杂志

AIM: The role of cyclic adenosine monophosphate (cAMP)-dependent protein kinase (PKA) in the induction and maintenance of spinal long-term potentiation (LTP) was evaluated. METHODS: The C-fiber evoked field potentials were recorded at the superficial layers of spinal dorsal horn at the lumbar enlargement. RESULTS: (1) 8-Br-cAMP induced LTP of C-fiber evoked field potentials and 8-Br-cAMP-induced LTP occludes tetanus-induced LTP. (2) Rp-CPT-cAMPS, an inhibitor of PKA, blocked the induction of spinal LTP and reversed established LTP of C-fiber evoked field potentials in a time-dependent manner. (3) In the presence of anisomycin, a protein synthesis inhibitor, the potentiation induced by 8-Br-cAMP was completely blocked. (4) PD98059, a selective inhibitor of mitogen-activated protein kinase (MAPK),completely blocked the 8-Br-cAMP-induced LTP.CONCLUSION: Activation of PKA signal pathway in spinal dorsal horn may be crucial for the induction and the early-phase maintenance of LTP of C-fiber evoked field potentials.
