Objective To discuss the expression and clinical significance of vascular endothelial growth factor (VEGF)-C and nm23-H1 in colorectal carcinoma.Methods Immunohistochemical staining was employed to determine the expression of VEGF-C and nm23-H1 in the carcinoma tissues of 120 cases with colorectal carcinoma and in the adjacent mucosal tissues of 55 cases as control,and analyzed their correlation with cliniopathological features and prognosis.Results The positive expression of VEGF-C in the carcinoma tissues was 71.7％ (86/120),significantly higher than that in the adjacent mucosal tissues [21.8 ％ (12/55)],and there was significant difference (x2 =35.186,P ＜ 0.01).The positive expression of nm23-H1 in the carcinoma tissues was 57.5％ (69/120),significantly lower than that in the adjacent mucosal tissues [90.9％ (50/55)],and there was significant difference (x2 =18.351,P ＜ 0.01).The expression of VEGF-C was significantly correlated with lymph node metastasis (P ＜ 0.05),and the expression of nm23-H 1was significantly correlated with lymph node metastasis and pathological type (P ＜0.01 or ＜0.05).The expression of VEGF-C and nm23-H1 did not show a significant correlation with gender,age,tumor size,tumor site and depth of invasion (P ＞ 0.05).Spearman correlation analysis showed that the expression of VEGF-C was negatively correlated with the expression of nm23-H 1 in colorectal carcinoma (r =-0.472,P ＜0.01).Conclusions The joint detection of VEGF-C and nm23-H1 expression is very promising in prediction of the prognosis of patients with colorectal carcinoma.However,whether it can be used as a marker in prognosis judgment need further investigation.

Objective To appraise the postoperative anti-reflux function of vertical esophagogastic valve-plasty anastomosis for cardiac cancer.Methods Forty patients with cardiac cancer were randomly divided into study group and surgery control group,with 20 patients in each group.The study group underwent vertical esopagogastric valve-plasty anastomosis,while the surgery control group underwent conventional esophagogastrostomy.Ten healthy volunteers were recruited as normal control group.A 24-hour esophageal pH monitoring and endoscopy check-up was carried out in all experimental subjects at 90 days postoperatively.Results All of the pH monitoring indexes in study and surgery control groups were higher than those in normal control group(P

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.

With the widespread application of colorectal cancer screening, the surveillance and management of the increasing number of screened population has become a pivotal aspect in preventing and controlling colorectal cancer. In recent years, researches have been conducted on the risk of colorectal cancer incidence and mortality in the population after screening. At the same time, various organizations in Europe and the United States have continuously updated colonoscopy surveillance after screening and polypectomy based on the latest research evidence. In this review, we summarized the current progress of studies on colorectal cancer risk in post-screening colorectal cancer populations and the key points of relevant guideline updates, in order to provide a reference for conducting relevant studies and formulating surveillance guidelines or consensus in China.

Objective To investigate the mechanisms that mediate the neuroprotective effect of the intestinal microbial metabolite sodium butyrate(NaB)in a mouse model of Parkinson's disease(PD)via the gut-brain axis.Methods Thirty-nine 7-week-old male C57BL/6J mice were randomized equally into control group,PD model group,and NaB treatment group.In the latter two groups,PD models were established by intraperitoneal injection of 30 mg/kg 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)once daily for 5 consecutive days,and normal saline was injected in the control group.After modeling,the mice received daily gavage of NaB(300 mg/kg)or an equal volume of saline for 14 days.Behavioral tests were carried out to assess the changes in motor function of the mice,and Western blotting was performed to detect the expressions of tyrosine hydroxylase(TH)and α-synuclein(α-syn)in the striatum and nuclear factor-κB(NF-κB),tumor necrosis factor(TNF-α),interleukin 6(IL-6),and the tight junction proteins ZO-1,Occludin,and Claudinin the colon.HE staining was used to observe inflammatory cell infiltration in the colon of the mice.RNA sequencing analysis was performed to identify the differentially expressed genes in mouse colon tissues,and their expressions were verified using qRT-PCR and Western blotting.Results The mouse models of PD with NaB treatment showed significantly increased movement speed and pulling strength of the limbs with obviously upregulated expressions of TH,Occludin,and Claudin and downregulated expressions of α-syn,NF-κB,TNF-α,and IL-6(all P<0.05).HE staining showed that NaB treatment significantly ameliorated inflammatory cell infiltration in the colon of the PD mice.RNA sequencing suggested that Bmal1 gene probably mediated the neuroprotective effect of NaB in PD mice(P<0.05).Conclusion NaB can improve motor dysfunction,reduce dopaminergic neuron loss in the striatum,and ameliorate colonic inflammation in PD mice possibly through a mechanism involving Bmal1.
