Objective To discuss the perioperative nursing for patients with Laparoscopic resection of gastrointestinal stromal tumors. Methods A retrospective study was carried out in 18 patients with gastrointestinal stromal tumors on the effect of perioperative nursing and surgery. Results The gastrointestinal stromal tumors were resected under Laparoscopy with average operation time of 70 minutes. Blood loss volume during the operation was 20 to 50 ml. All patients recovered well with hospitalization days of 4 to 9 days. No relapse or metastasis was seen after 6 to 22 months of follow-up visit. Conclusions Laparoscopic resection of gastrointestinal stromal tumors was safe and effective. Perioperative nursing had significant effect on the recovery of patients.

AIM and METHODS: To investigate the effect of electrical stimulation of ventlal septal area (VSA) on discharge of pyrogen - treated thermosensitive neurons in preoptic anterior hypothalamus (POAH) region, the discharging rate of thermosensitive neurons in the POAH region of 32 New Zealand white rabbits were recorded by using extracellular microelectrode techinque. RESULTS: (1) Intraceretroventricularly (i c v) injection of interleukin - 1?(IL - 1?) caused decrease of discharging rate of warm - sensitive neurons and increased in discharging rate of cold - sensitive neurons in POAH regions. (2) These effects could be reversed by electrical stimulation of VSA. CONCLUSION: VSA may play a central role of negative regulation in thermoregulation of pyrogen - treated animal.

ObjectiveTo investigate the change of lipoxin A4 (LXA4), leuotriene B4(LTB4) in blood and urine and leukocyte 15-lipoxygenase (15-LO) of the children with acute poststreptococcal glomendonephritis (APSGN) and to evaluate its significance. MethodsBlood and urinary levels of LXA4 and LTB4 were measured with ELISA within 3 days (acute phase), 10 to 14 days (early resolution phase) and 6 to 8 weeks (late resolution phase) respectively after onset of APSGN in 22 patients. In 8 children with APSGN, expression level of leukocyte 15-LO mRNA was examined with RT-PCR. Leukocyte LTB4 synthesis was assessed with ELISA. Chemotactic effect of LTB4, LXA4 and 15-S-hydroxyeicosatetraenoic acid (15-S-HETE) on neutrophils was determined by in vitro chemotaxis assay. Twenty-two healthy children were served as control. ResultsBlood and urinary levels of LXA4 and leukocyte 15-LO mRNA were up-regnlated in acute phase, further increased in early resolution phase, and decreased in late resolution phase of APSGN, which were stir higher than those in the controls (P＜0.01). Blood and urinary levels of LTB4 were increased in acute phase (P＜0.01) and then were decreased in early resolution phase and hte resolution phase of APSGN, which were still higher than those in the controls (P＜0.01). Administration of 15-S-HETE or LXA4 in vitro inhibited LTB4-induced chemotactic effect on neutrophils of the patients,and inhibited the production of leukocyte LTB4. ConclusionsChanges of blood and urinary levels of LXA4 and LTB4 in early resolution phase of APSGN are contrary. 15-S-HETE and LXA4may play a role in anti-inflammation and resolution of APSGN via inhibiting LTB4.

Objective:This study aimed to investigate the expressions of EZH2 and Ki-67 in the salivary adenoid cystic carcino-ma (SACC) of humans and their correlation. Methods:A total of 42 cases of SACC tumor tissues and 5 cases of normal tissues were considered to determine the expressions of EZH2 and Ki-67 by immunohistochemistry. The relationship and correlation of such expres-sions with the clinicopathological characteristics were also analyzed. Results:The expression of EZH2 was notably higher in SACC than in normal tissues (P<0.05). EZH2 expression was detected in 66.67%(28/42) of the tumor tissues. This expression was correlated with pathological grade and clinical stage. By contrast, EZH2 expression did not correlate with gender, age, and localization. EZH2 was not expressed in normal tissues. The incidence of EZH2 expression in the Ki-67 positive group was 75.76%(25/33) and the incidence in the Ki-67 negative group was 33.33%(3/9). The difference between the two groups was statistically significant (P<0.05). Conclu-sion:The increased expression of EZH2 in SACC was related to tumor proliferation. EZH2 may participate in tumor cell proliferation via cell cycle management.

Abstract］　AIM and METHODS:The recent work from our laboratory showed that ventral septal area (VSA) played a negative-regulatory central role in thermoregulation during endogenous pyrogen-induced fever. In order to further investigate the role of VSA in the antipyretic mechanism, we observed the effects of electrical stimulation of VSA on firing characteristics of thermosensitive neurons in preoptic anterior hypothalamus (POAH) by using extracellular microelectrode technique on 32 New Zealand white rabbits treated with interleukin-1 β (IL-1β) intracerebroventriculary (ICV). RESULTS:(1)Injection of IL-1β decreased discharging rate of warm-sensitive neurons in POAH. Electrical stimulation of VSA remarkably decreased thermosensitive coefficient of warm-sensitive neurons. (2)Injection of IL-1β caused increase in discharging rate of cold-sensitive neurons in POAH. Electrical stimulation of VSA remarkably increased thermosensitive coefficient of cold-sensitive neurons. CONCLUSTION:VSA may have an antipyretic effect through affecting the firing characteristics of thermosensitive neurons in POAH during IL-1β-induced fever.

Objective To confirm the predictive value of diaphragm thickening fraction (DTF) on successful weaning by bedside ultrasound in patients with myasthenia gravis crisis. Methods A prospective study was conducted. The patients with myasthenia gravis crisis undergoing mechanical ventilation admitted to Department of Critical Care Medicine of the Affiliated Hospital of Qingdao University from March 2015 to February 2017 were enrolled. All patients underwent a low level pressure support mode of spontaneous breathing test (SBT), and rapid shallow breathing index (RSBI) was recorded. The indicators of right diaphragm thickness at the end of inspiration (DTei) and expiration (DTee) were determined by bedside ultrasound at 5 minutes and 60 minutes of SBT, and DTF was calculated, the changes in above parameters were observed during SBT. The patients were divided into successful weaning group and failure weaning group, and the differences in above indexes were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of DTF and RSBI at 60 minutes of SBT on successful weaning. Results A total of 37 patients were enrolled in the study. Ultrasonic measurement data of 63 person-times at 5 minutes of SBT and 50 at 60 minutes of SBT were obtained. There were no statistical differences in RSBI, DTei, DTee, and DTF at 5 minutes of SBT between successful weaning group (n = 33) and failure weaning group (n = 30). At 60 minutes of SBT, compared with successful weaning group (n = 33), the patients in failure weaning group (n = 17) had a higher RSBI (times·min-1·L-1: 80.41±29.08 vs. 63.94±23.84, t = 2.146, P = 0.037), and lower DTee, DTei and DTF [DTee (mm): 22.00±6.25 vs. 25.45±4.99, t = 2.127, P = 0.039; DTei (mm): 27.94±6.19 vs. 38.48±6.15,t = 5.731, P = 0.000; DTF: (24.46±14.11)% vs. (62.04±30.21)%, t = 4.845, P = 0.000]. There were no statistical differences in RSBI, DTei, DTee, and DTF between 5 minutes and 60 minutes of SBT in 33 person-time successful weaning (all P > 0.05). In 17 person who had 60 minutes of SBT but failed weaning, the RSBI at 60 minutes of SBT was significantly higher than that at 5 minutes (times·min-1·L-1: 80.41±29.08 vs. 57.29±22.46, t = 2.400, P = 0.029), and DTei and DTF were significantly decreased [DTei (mm): 27.94±6.19 vs. 35.35±6.84, t = 3.024, P = 0.000; DTF:(24.46±14.11)% vs. (61.89±23.97)%, t = 5.810, P = 0.000], but the change of DTee during SBT showed no statistical significance. ROC curve analysis showed that the area under ROC curve (AUC) of DTF at 60 minutes of SBT for predicting successful weaning was 0.898; when DTF ≥ 27.9% as the cut-off point, the sensitivity was 93.9%, specificity was 70.6%. The AUC of RSBI for predicting successful weaning was 0.669; when RSBI ≥ 86.50 times·min-1·L-1 as the cut-off point, the sensitivity was 81.8%, specificity was 52.9%. Conclusion DTF at 60 minutes of SBT is the effective index of successful weaning prediction in mechanical ventilation patients with myasthenia gravis crisis.

Purpose To evaluate the diagnostic value of contrast-enhanced ultrasound (CEUS) in papillary thyroid carcinomas (PTC) by exploring the relationship between quantitative parameters of time-intensity curve (TIC) of CEUS for PTC and tumor size and metastasis of cervical lymph nodes.Materials and Methods 124 patients with PTC confirmed by surgery and pathology in the Affiliated Hospital of Qingdao University were retrospectively analyzed.According to maximum diameter of lesions (D),the lesions were divided into three groups with D＜1.0 cm,1.0 cm ≤ D ≤ 2.0 cm and D＞2.0 cm.The lesions were also divided into LN(+) group with lymph node metastasis and LN(-) group without lymph node metastasis based on pathology of cervical lymph nodes.The features of CEUS and quantitative parameters of TIC of the above groups were analyzed.Results ① The CEUS showed that the PTC nodules were mainly concentric and heterogeneous enhancement.Thyroid carcinoma with D＜1.0 cm and 1.0 cm≤D≤2.0 cm showed low enhancement (45/57,31/42),while thyroid carcinomas with D＞2.0 cm exhibited high enhancement (14/25),and the difference was significant (P＜0.05).① With the increase of the diameter of PTC,the peak intensity [(12.75 ± 3.77)％,(15.53 ± 3.62)％,(18.11 ± 4.28)％],the area under the curve [(820.52±289.19)％.s,(873.84± 156.19)％· s,(1118.8± 152.48)％ ·s] and the ratio of the perfusion defects (24.56％,52.38％,72.00％) were increased,and the differences were statistically significant (P＜0.05).③ The cervical lymph node metastasis rate of PTCs with isoenhancement or hyperenhancement patterns showed by CEUS was significantly higher than that with hypoenhancement (P＜0.05).The peak intensity and the area under the curve of LN (+) group were higher than that of LN (-) group,and the differences were statistically significant (P＜0.05).Conclusion There were significant differences in imaging features of CEUS between the PTC nodules with different size and lymph node metastasis,which can provide valuable information for clinical diagnosis.

AIM and METHODS: To investigate the functional connection between the preoptic anterior hypothalamus (POAH) and the ventral septal area (VSA) in fever mechanism, the firing rates of thermosensitive neurons in the VSA of 26 New Zealand white rabbits were recorded using extracellular microelectrode technique. RESULTS: The firing rates in both types of thermosensitive neurons in the VSA had no significant changes after intracerebroventricular (icv) injection of artificial cerebrospinal fluid(ACSF). When interleukin-1β (IL-1β) was given (icv), the firing rate of the warm-sensitive neurons was increased significantly and that of the cold-sensitive neurons was decreased remarkably. The effects of IL-1β on the changes of firing rate in thermosensitive neurons of the VSA were reversed by electrical stimulation of the POAH. CONCLUSION: The roles of positive and negative thermoregulatory centers in the interaction between the POAH and VSA are closely linked during endogenous pyrogen induced fever.
