Objective To explore the influence of humanistic care on psychological stress in diag-nostic process for patients with lung cancer. Methods 40 suspicious lung cancer patients were divided into the experimental group and the control group according to admission sequence. The control group ac-cepted routine care, the experimental group received humanistic care based upon routine care. Zung's self-rating anxiety scale(SAS) and self- rating depression scale(SDS) were applied in two groups at admission day and 2 days post- diagnosis, the results underwent comparison with norm using t test. Results On ad-mission day 2 groups showed no significant difference in SAS and SDS, 2 days post- diagnosis the SAS and SDS score were evidently lower than those of the control group. Conclusions Lung cancer patients were in anxiety and depression condition during diagnostic process, and humanistic care could effectively relieve their psychological stress.

In order to investigate the neuroprotective effects of cyclin-dependent kinase-5 (cdk-5) inhibition in mice with Niemann-Pick disease type C (NPC) (npc(-/-)), recombinant adeno-associated virus (rAAV) carrying the small interfering RNA (siRNA) specific for cdk-5 gene was injected into 3-day-old npc(-/-) mice intracerebroventricularly. The rAAV-GFP-injected age-matched npc(-/-) mice and non-surgery age-matched npc(-/-) mice were employed as controls (n=6-10/group). From the 4th to 8th week after the treatment, mice were weighed, and evaluated for limb motor activity by using the coat hanger test once a week. Eight-week-old npc(-/-) mice were sacrificed by decapitation, and brains were quickly dissected and halved sagittally. Immunohistochemistry, Western blotting, and HE staining were used to evaluate the neuropathology in npc(-/-) mice. The results showed that rAAV-cdk-5-siRNA-GFP significantly reduced the number of axonal spheroids, delayed the death of Purkinje neurons, ameliorated motor defects in npc(-/-) mice, and significantly attenuated the hyperphosphorylation of tau proteins. These data suggested that inhibition of cdk-5 activity has neuroprotective effect on neurons in NPC mice.

Background Endothelin-1 (ET-1) is an active regulator of intraocular pressure.The ET-1 level in aqueous humor is elevated in primary open-angle glaucoma,normal intraocular tension glaucoma and the animal model of glaucoma.There is now accumulating evidence for a role of ET-1 in the pathogenesis of glaucoma.However,the effect of ET-1 on the phagocytic function in trabecular meshwork cells (TMCs) is unclear.ObjectiveThis study is to observe the effect of ET-1 on the phagocytic function in cultured human TMCs.Methods Human trabecular meshwork tissue was obtained from healthy donator and cultured and subcultured in vitro by the explant culture method.The third passage of human TMCs were incubated with fluoresent red-labeled latex beads for 0,4,8,12,24,48 and 72 hours.The phagocytic kinetics of human TMCs were continuously evaluated by counting the number of latex beads in TMCs using a fluorescence microscope.Depending on the concentrations of ET-1 in culture medium,the TMCs were divided into control group (without ET-1),low-dose ET-1 (10~(-9)mol/L) treatment group,middle-dose ET-1 (10~(-8)mol/L) treatment group and high-dose ET-1 (10~(-7) mol/L) treatment group.In addition,based on the addition of endothelin receptor (ETAR) antagonist,the TMCs were divided into control group (without ETAR antagonist),ET-1 (10~(-8)mol/L) treatment group,ETAR antagonist (1×10~(-7)mol/L BQ123+10~(-8)mol/L ET-1) treatment group and ETBR antagonist(1×10~(-7) mol/L BQ788+10~(-8) mol/L ET-1)treatment group.TMCs of each group were incubated with latex beads,and the numbers of latex beads in TMCs were counted under a fluorescent microscope.Results Cultured HTM cells showed positive reactions for FN,LN,NSE and negative response for FⅧRag.The phagocytic kinetics test revealed that the latex beads were detected 4 hours after incubation.The density of latex beads was gradually increased with the delay of incubation duration and peaked at 24 hours.The number of the latex beads saturated after 48 hours of incubation.However,the number of latex beads in TMCs was significantly reduced after the addition of ET-1 in a dose-dependent manner (F=28.91,P＜0.05).The number of latex beads in the ET-1 group was less than that in the control group and the ETAR receptor antagonist group (q=13.7228,q=9.4312,P＜0.05).No significant difference was found in latex beads number between the ET-1 group and the ETBR antagonist group (q=1.1600,P＞0.05).Conclusion ET-1 inhibits the phagocytic function of human TMCs and ETAR plays a partial role in the phagocytic function of human TMCs.

Objective To evaluate the significance of platelet activation and the expression of inter-leukin (IL)-1β in patients with RA. Methods The activation of platelets and the expression of IL-1β in pla-telets in 50 RA patients(22 high-active, 28 mediate/low active ) and 30 normal controls were determined us-ing flow cytometry. Meanwhile, inflammatory indicators such as erythrocyte sedimentation(ESR), C-reactive protein (CRP) and DAS28 were also recorded. T test and correlation analysis were performed. Results The platelet activation in RA group(19.2±4.8) was higher than the control group(9.0±2.9)(t=10.5, P=0.001). The expression of IL-1β in platelets in RA group(41±11) was higher than control group(21±8)(t=9.01, P =0.000) .The platelet activation in high-active RA group(22 ±4) was higher than mediate/low active RA group(17 ±4)(t =3.96,P =0.001). The expression of IL-1β in platelets in high-active RA group(45 ±10) was higher than mediate/low active RA group (38 ±10)(t =2.329,P =0.024). The expression of IL-1β in platelets in RA group was positively correlated with the level of ESR、CRP and DAS28 (r value and P value were 0.576, 0.578, 0.618 and 0.000, 0.000, 0.000 respectively). Conclusion The platelets of patients with RA are activated and may suggest that IL-1β, which may associate with disease activity. Our research suggest that platelet may play a role in the inflammatory process of RA by secreting IL-1β.

Objective:To evaluate the efficacy of combination of dexmedetomidine and compound lidocaine cream for the prevention and treatment of the stress responses during recovery from general anesthesia in the patients undergoing transnasal transphenoidal pituitary adenoma resection.Methods:A total of 90 patients, aged 18-64 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective pituitary tumor resection by transsphenoidal approach with general anesthesia, were divided into 3 groups ( n=30 each) by the random number table method: combination of dexmedetomidine and compound lidocaine cream group (D-L group), dexmedetomidine group (D group) and compound lidocaine cream group (L group). Compound lidocaine cream 2 g was applied to the anterior 1/3 of the tracheal tube and surface of the cuff in D-L and L groups, and paraffin oil was applied to the surface of the tracheal tube in group D. In D-L and D groups, dexmedetomidine 0.5 μg/kg was intravenously infused for 10 min at 30 min before the end of surgery, while the equal volume of normal saline was given in group L. Heart rate and mean arterial pressure were continuously monitored during peritracheal extubation, and the occurrence of responses to extubation was recorded.The optic nerve sheath diameter (ONSD) was measured by ultrasound after entering the operating room(t 0), after anesthesia induction(t 1), and at 5 min after extubation (t 2). The bucking and agitation scores were recorded during recovery from anesthesia. Results:Compared with group D and group L, the incidence of bucking and responses to extubation was significantly decreased in group D-L (27%, 37%, 6%; 23%, 27%, 3%, respectively, P<0.05). Compared with group L, the incidence of agitation was significantly decreased in D-L and D groups (37%, 10%, 13%, respectively, P<0.05). No severe bucking and agitation occurred in group D-L.There was no significant difference in ONSD at each time point among three groups ( P>0.05). Conclusion:Combination of dexmedetomidine and compound lidocaine cream performs better than either alone and can prevent and treat stress responses during recovery from general anesthesia in the patients undergoing transnasal transsphenoidal pituitary adenoma resection.
