Objective To investigate the application of serum soluble interleukin-2 receptor(sIL-2R)and soluble tumor necrosis factor receptor Ⅱ (sTNFR Ⅱ) in extrapulmonary organ involvement sarcoidosis.Methods Of 28 cases with sarcoidosis which were in active period,12 cases were in extrapulmonary organ involvement subgroup,16 cases were in pure pulmonary lesions subgroup.Serum sIL-2R and sTNFR Ⅱ of the two groups were detected by enzyme linked immunosorbent assay and compared.Results The expression level of sIL-2R in extrapulmonary organ involvement subgroup was (1.60 ± 0.80) μg/L,significantly higher than that of pure pulmonary lesions group,and there was significant difference((1.00±0.29)μg/L,t =2.764,P＜0.05);and the expression level of sTNFR Ⅱ in extrapulmonary organ involvement subgroup was (1.09 ± 0.24) μg/L,significantly higher than that of pure pulmonary lesions group,and the difference between the two groups was statistically significant((0.85±0.29) μg/L,t =2.183,P＜0.05).Conclusion The expression level of peripheral blood serum sIL-2R and sTNFR Ⅱ may serve as the important indexes to judge the extrapulmonary organ involvement sarcoidosis.

Objective To investigate the efficacy and the indication and the management of perioperative complications in treatment of infra- kidney abdominal aortic aneurysm (AAA) by using endovascular graft exclusion (EVGE). Methods From April 2006 to September 2008, 24 patients with infra- kidney abdominal aortic aneurysms were diagnosed by contrast-enhanced CT or MRI scan. Vascular access was obtained through the bilateral femoral artery after arteriotomy and stent-graft was deployed into AAA of below the renal artery to occlude the left over cavity of AAA. The stent- graft was extended and anchored to the both side wall of AAA, the blood flow enter into the arteria iliaca communis through the sten't.Results Stent-graft deployment was successfully performed in all the patients. Immediate aortography after the procedure showed no leakage in 20 patients and the type Ⅰ minor leakage in 4 patients. No stent movement or organ and both lower extremities ischemia was found at the early post operative stage in all the patients. Six months after the operation, in all the 24 patients, contrast-enhanced CT scan showed the disappearance of the aneurysm and thrombosis at the level of the stent. Conclusions EVGE is simple,minimally invasive,less complication and quick recovery after operation. Thus it becomes first choice for the treatment of AAA for the elder patients.

OBJECTIVETo assess referral cases for root canal therapy to provide clinical evidence with establishment of referral system.

METHODSA questionnaire was designed to collect 312 cases (355 teeth) referred to Department of Conservative Dentistry and Endodontics, West China School of Stomatology, Sichuan University for root canal therapy from April to June in 2011. The questionnaire consisted of questions such as age, gender, occupation, general disease and medical histories of patients, sources. Difficulty of treatment before therapy and reasons for referral were evaluated.

RESULTSIn 355 referral teeth, the most were mandibular first molars (17%), the greatest percentage of reasons were calcified root canals (30%), the second was root canal retreatment (24%). 72% of teeth belong to the complicated difficulty (Class III), while 7% were listed as the uncomplicated difficulty (Class I). No significantly difference from different sources was found (P = 0.9).

CONCLUSIONEstablishment of referral system needs cooperation with every dentist. Difficulty of cases for root canal therapy before treatment should be first evaluated to treat or to refer. Referral cases for root canal therapy should be treated by endodontist of corresponding level according to the difficulty.

Objective: To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) combined with donepezil on the cognition of persons with post-stroke cognitive impairment (PSCI) and their ability to perform activities of daily living (ADL). Methods: A total of 106 PSCI patients were randomly divided into an observation group and a control group using a random number table. Those in the observation group received 10Hz rTMS (5 seconds on and 25 seconds off for 20 minutes daily) and donepezil daily, 5 days per week for 4 weeks, while those in the control group were provided with donepezil but only sham rTMS on the same schedule. Before and after 4 weeks of treatment, the Montreal cognitive assessment scale (MoCA), the Rivermead behavior memory test (RBMT) and the modified Barthel index (MBI) were used to evaluate the subjects′ cognitive functioning, memory capacity and ADL ability. The latency and amplitude of auditory event-related potential P300 were also assessed using a myoelectric evoked potential apparatus. Results: After the treatment, improvement was observed in all the measurements of both groups. After the treatment, the average MoCA, RBMT and MBI scores, as well as the latency and amplitude of P300 in the observation group were all significantly better than among the control group. Conclusions rTMS can supplement donepezil′s ability to improve the cognition and ADL ability of persons with PSCI. Such therapy is worthy of clinical promotion and application.

PURPOSE: The present study aimed to investigate the value of apolipoproteins, including ApoA-1, ApoC-III, and ApoE, in patients with small cell lung cancer (SCLC) as potential biomarkers for diagnosis, prognosis, and cancer progression. MATERIALS AND METHODS: Lung samples were collected from 89 patients with SCLC. Nineteen lung samples from non-small cell lung cancer (NSCLC) patients and 12 normal lung tissues were used as controls. Expression profiles of ApoA-1, ApoC-III, and ApoE in different samples were examined using immunohistochemical methods, and the expression levels were correlated with cancer types, treatment, and outcomes using chi-square and Mann-Whitney tests. RESULTS: Expression of ApoA-1 and ApoC-III in SCLC was significantly different, compared with that in NSCLC and normal lung tissues, and was correlated with recurrence of SCLC. Patients undergoing neoadjuvant chemotherapy before surgery showed significantly reduced expression of ApoA-1 and increased expression of ApoC-III and ApoE. Nevertheless, the expression levels of ApoA-1, ApoC-III, and ApoE were not correlated with SCLC staging. CONCLUSION: ApoA-1 and ApoC-III may be used as differentiating and predictive markers for SCLC. ApoA-1, ApoC-III, and ApoE may be used to monitor the efficacy of chemotherapy.

Objective:To explore the effect of healthcare failure mode and effect analysis (HFMEA) in reducing the incidence of nursing interruption with negative outcome in operating room, so as to maximize the smooth progress of the surgical process.Methods:This was a quasi experimental study. The gastrointestinal surgery room of Shandong Provincial Hospital Affiliated to Shandong First Medical University was selected for the study. According to the surgical sequence, 38 surgeries performed in the gastrointestinal surgery suite from August 15-30, 2021 were set as the control group, and the conventional healthcare cooperation model process was implemented; 42 surgeries performed from September 15-30, 2021 were set as the intervention group, and the operating room under the HFMEA model was implemented negative outcome care disruption event management process.A video tracking method combined with a surgical care disruption event register was used to investigate the occurrence of negative outcome care disruption events in the operating room, comparing the number, duration, source of disruption events and the incidence of near miss events in the operating room between the control group and the intervention group.Results:In the control group, there were 38 observed surgeries, 190 negative outcome care interruptions, negative outcome interruptions of (5.26 ± 1.02) min duration, and no near misses; in the intervention group, there were 42 observed surgeries, 84 negative outcome care interruptions, negative outcome interruptions of (2.06 ± 0.08) min duration, and no near misses. There were statistically significant differences in the number, duration of negative outcome care interruptions between the intervention group and the control group ( χ2 = - 18.71, t = - 20.28; all P<0.01). There was statistically significant difference in the source of negative outcome care interruptions between the intervention group and the control group ( χ2 = - 12.71, P<0.01). Conclusions:HFMEA model can effectively reduce the number of negative nursing interruptions in the operating room, shorten the duration of interruptions, and minimize potential safety hazards caused by nursing interruptions, which is conducive to ensuring the safety of patients.

Objective:To investigate the effect of SCN1A gene polymorphism (SCN1A-rs3812718) on the alterations of spontaneous brain activity using amplitude of low-frequency fluctuations (ALFF) of MR in patients with temporal lobe epilepsy (TLE).Methods:A total of 37 TLE patients (TLE group) admitted to the Epilepsy Center of the 900th Hospital of Joint Logistic Team from March 2018 to August 2019 were retrospectively analyzed, and another 28 healthy volunteers matched for gender, age, and years of education with the TLE group were selected as the healthy control group (HC group). Sixty-five subjects were divided into four groups by genotype and diagnosis: 34 cases in AA/AG-TLE subgroup, 3 cases in GG-TLE subgroup, 20 cases in AA/AG-HC subgroup and 8 cases in GG-HC subgroup. All subjects underwent sagittal 3D-T 1WI and resting-state functional MRI using a Siemens 3.0 T Trio Tim MR scanner. Then ALFF values of the four groups were calculated using DPABI by the MATLAB 2010 platform. The ALFF values between two groups were compared by independent samples t-test. The ALFF values of different genotypes at rs3812718 locus in TLE and HC group were analyzed by multivariate analysis of variance to find out the corresponding brain regions with interaction, and then post hoc simple effect analysis was performed. Results:The ALFF values in TLE group significantly increased in left marginal lobe, left parahippocampal gyrus, left fusiform gyrus, left hippocampus, right insular lobe and right inferior temporal gyrus (Alphasim corrected P<0.001) and decreased in the left superior frontal gyrus, left middle frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right precuneus, left precuneus, bilateral cingulate gyrus and right angular gyrus (Alphasim correction P<0.05) compared with HC group. Subjects carrying the non-risk G allele had higher ALFF values in the right inferior temporal gyrus, right fusiform gyrus, and right cerebellum than subjects carrying the risk A allele ( t=3.30, Alphasim corrected P=0.002). There was a significant interaction effect on posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus, left superior parietal lobule and right precuneus of TLE patients with SCN1A-rs3812718 genotype. Post-hoc simple effect analysis showed that ALFF significantly increased in the left posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus and left fusiform gyrus in GG-TLE subgroup ( t=5.97, P<0.001), but significantly decreased in the right superior parietal lobule, right precuneus, right posterior cerebellar lobe in AA/AG-TLE subgroup compared to the HC group. Compared with GG-TLE subgroup, ALFF in left posterior cerebellar lobe, left fusiform gyrus and left inferior temporal gyrus decreased in AA/AG-TLE subgroup. Conclusion:SCN1A gene polymorphism in the rs3812718 locus affects spontaneous neural activity in resting state, which may be one of the pathophysiological mechanisms of TLE.
