Objective To investigate the risk of death between older and non-older critical patients in intensive care unit (ICU) in Shuyang People's Hospital.Methods A retrospective cohort study was conducted. The critical patients who aged 15 or above, and admitted to ICU of Shuyang People's Hospital from January 2014 to December 2016 were enrolled, and all the data was collected from theregistration and electronic medical records in the ICU. The prevalence and causes of death in ICU critical patients during the study period were observed. The patients were divided into elderly group (65 years and older) and non-elderly group (15-65 years), and logistic regression analysis was performed for the risk of death in the two groups.Results During the study period, 2707 critical patients in emergency were admitted to the ICU of Shuyang People's Hospital, and patients not satisfied the inclusion criteria were excluded. Finally, a total of 2466 patients were enrolled in the analysis with the male and female ratio of 1.6 : 1, an average age of (61.8±17.3) years, a median Glasgow coma scale (GCS) score of 6 (4, 8), and with a median ICU stay of 3 (1, 6) days. In 2466 critical patients, the most common cause of critical state was spontaneous intracerebral hemorrhage (25.5%) and traumatic brain injury (17.0%), with a fatality rate of 46.0% and 39.5% within first 7 days respectively. Compared with the non-elderly patients (n = 1415), the incidences of death of the elderly patients (n = 1051) due to traumatic brain injury, cerebral infarction, heart failure/cardiovascularcrisis, and respiratory critically ill were significantly increased (9.4% vs. 4.7%, 2.9% vs. 0.8%, 5.0% vs. 2.1%, 2.5% vs. 1.0%, respectively), while the incidence of death for pesticide/drug poisoning in the elderly group was significantly lower than that in the non-elderly group (0.2% vs. 1.2%, allP < 0.01). Stepwise logistic regression analysis showed that traumatic brain injury [hazard ratio (HR) = 1.878, 95% confidence interval (95%CI) = 1.233-2.864,P = 0.003), cerebral infarction (HR = 0.435, 95%CI = 0.229-0.826, P = 0.011), heart failure/cardiovascular crisis (HR = 0.399, 95%CI = 0.238-0.668,P = 0.000), and respiratory critically ill (HR = 0.239, 95%CI = 0.126-0.453,P= 0.000) in the older patients were significantly high risk factors of death as compared with those in non-older patients.Conclusions In the general ICU, the most common cause is spontaneous intracerebral hemorrhage and traumatic brain injury in critical patients with a high fatality rate. The risk of death in elderly patients with severe traumatic brain injury, cerebral infarction, heart failure/cardiovascular crisis, respiratory critically ill is higher than that of the non-elderly patients.

Objective To evaluate reference range for fasting venous blood cells in the healthy 51 584 elderly people from Shuyang,China.Methods Totally 1000 non-old people and 51 584 elderly people were involved in this study.Fasting venous blood cells were collected from each group of subjects using standard procedures.The collected aliquots were processed according to standard operating procedures to determine participants' complete blood counts.Non-parametric methods were employed to calculate the reference intervals and 95 ％ confidence intervals for complete blood counts by Sysmex XE-2100 blood cell analyzer.Results The reference ranges of fasting venous blood cells in elderly subjects (male,female) were [(3.25-9.45) × 109/L and (3.35-9.39) × 109/L,WBC];[(3.87-5.55) × 1012/L and (3.71-5.19) × 1012/L,RBC] ; [(116.2-169.5)g/L and(107.4-153.6)g/L,Hb] ; [(37.2-52.4) ％ and(35.2-48.6) ％,HCT] ; [(86.3-104.8)fl and (85.2-103.5) fl,MCV] ; [(27.0-33.4) pgand(26.4-32.5)pg,MCH]; [(297.1-335.4)g/L and(293.3-330.5)g/L,MCHC];[[(38.4-54.2) and (38.6-52.9),RDW-SD]; [(11.3-15.4)％ and(11.4-15.3)％,RDW-CV];[(98.8-303.8) × 109/L and (109.9-334.8) × 109/L,PLT] ; [(1.10-3.42) and (1.20-3.78) ml/L,PCT];[(11.2-15.6) fl and(11.3-15.5)fl,MPV]; [[(8.89-16.7)％ and(9.48 17.1)％,PDW];[(20.3-49.1) ％ and (20.5-48.6) ％,PLCR],respectively.13 parameters of fasting venous blood samples in elderly people had statistically significant differences compared with non-old people (all P ＜0.05).Conclusions The reference range of fasting venous blood samples in elderly people are significantly different from non-old people.It is necessary to scientifically and reasonably establish the reference ranges for fasting venous blood cells in local elderly people.

A 20-year-old male patient presented with myalgia of upper limbs and myasthenia of extremities for more than 1 month. Physical examination showed diffuse erythema on the cheeks, upper eyelids, upper chest, neck and dorsa of the hands. The myodynamia of the proximal and distal muscles of upper and lower extremities was grade Ⅳ, Ⅴ, Ⅲ and Ⅴ respectively. Laboratory examinations revealed that the serum levels of creatine kinase, CK-MB and lactate dehydrogenase were 2103 U/L, 83 U/L and 489 U/L respectively, which were all above the normal range. Electromyogram revealed myopathic abnormality and normal nerve conduction velocity. Histopathology of gastrocnemius muscle showed hypertrophy and swelling of muscle fibers, disappearance or fuzziness of transverse striation, and intermuscular lymphoid cell infiltration. A biopsy of the skin lesion from the upper chest showed liquefaction degeneration of and colloid bodies in basal cell layer, perivascular lymphoid cell infiltration in the dermis. A diagnosis of dermatomyositis was established based on the clinical and laboratory findings. After management with intravenous prednisolone 80 mg once daily and symptomatic treatment for 4 weeks, the myodynamia of upper limbs was improved, serum levels of creatine kinase,CK-MB and lactate dehydrogenase reached the normal ranges. However, the myodynamia of lower limbs progressively deteriorated with the emergence of paresthesia. Enhanced MRI scan showed a tumor in the vertebral canal at the level of thoracic vertebra 11 to 12. A spherical encapsulated tumor measuring 3 cm in diameter was surgically removed. The tumor was diagnosed as paraganglioma in vertebral canal according to pathological and immunohistochemical findings. The patient was finally diagnosed with paraganglioma in vertebral canal superimposed on dermatomyositis.

Objective:To investigate the value of ultrasound in the diagnosis of intraneural perineurioma.Methods:From June 2015 to June 2022, 11 patients with intraneural perineurioma confirmed by surgery or biopsy in Provincial Hospital Affiliated to Shandong First Medical University were retrospectively collected, all of whom underwent high-frequency ultrasound examination. Clinical data and sonographic characteristics were collected. The maximum cross-sectional area of the affected nerve was recorded and compared with the corresponding site of the contralateral nerve.Results:All the 11 cases of intraneural perineurioma were single neuropathy. The sonogram showed that the affected nerve was spindle shaped and thickened. There was a statistical difference between the maximum cross-sectional area of the thickened intraneural perineurioma and the corresponding site of the contralateral nerve [(0.158±0.043)cm vs (0.044±0.012)cm, t=8.669, P<0.001]. The fascicles of the affected nerve were thickened with loss of normal fascicular definition, but there were still hyperechoic linear separation among the fascicles. Conclusions:High-frequency ultrasound may be a valuable technique for the diagnosis of intraneural perineurioma.

Programmed cell death 4 (PDCD4) is a RNA-binding protein that acts as a tumor suppressor in many cancer types, including colorectal cancer (CRC). During CRC carcinogenesis, PDCD4 protein levels remarkably decrease, but the underlying molecular mechanism for decreased PDCD4 expression is not fully understood. In this study, we performed bioinformatics analysis to identify miRNAs that potentially target PDCD4. We demonstrated miR-181b as a direct regulator of PDCD4. We further showed that activation of IL6/STAT3 signaling pathway increased miR-181b expression and consequently resulted in downregulation of PDCD4 in CRC cells. In addition, we investigated the biological effects of PDCD4 inhibition by miR-181b both in vitro and in vivo and found that miR-181b could promote cell proliferation and migration and suppress apoptosis in CRC cells and accelerate tumor growth in xenograft mice, potentially through targeting PDCD4. Taken together, this study highlights an oncomiR role for miR-181b in regulating PDCD4 in CRC and suggests that miR-181b may be a novel molecular therapeutic target for CRC.
