Objective To investigate the expression of EphA8 in colon cancer and its clinical significance.Methods Real-time quantitative polymerase chain reaction (RT-PCR) and Western blot were respectively used to assess the expressions of EphA8 mRNA and protein in normal colon mucosa cell line and colon cancer cell lines.Immunohistochemistry for EphA8 and vascular endothelial growth factor (VEGF) were performed in 98 cases of colon cancer and 12 matched normal mucosa tissues.CD31 immunohistochemical staining was used for microvascular density (MVD) counting.The relationships between the expression of EphA8 and the expression of VEGF and MVD,the clinical pathological significance,and the prognosis of patients were analyzed by statistical methods.Results EphA8 mRNA expressions were significantly higher in colon cancer cell lines than those in normal mucosa cell line (t =11.98,13.54,P ＜0.001).EphA8 protein expressions were significantly higher in colon cancer cell lines than those in normal mucosa cell line (t =4.63,P =0.006;t =4.92,P =0.004).The high expression of EphA8 was closely related to tumor size (x2 =22.97,P＜0.001),TNM stage (P＜0.001),differentiated degree (P =0.007)and lymph node metastasis (P＜0.001),distant metastasis (x2 =6.97,P =0.008) and poor survival rote (x2 =17.3,P ＜0.001).But it was not associated with the gender and age (x2 =1.36,P =0.30; x2 =0.83,P=0.44).Besides,EphA8 had positive correlation with the VEGF and MVD (r =0.434,P ＜0.001; r =0.584,P ＜0.001).Conclusion EphA8 may play important roles in the development and metastasis of colon cancer,which has potential clinical values in the therapeutic intervention and prognosis of colon cancer.

Objective To investigate different frequencies of glucocorticoids (GCs) on the tissue in a model of osteoporosis. Methods Thirtytwo three-month-old SD female rats were randomly divided into four groups: (1) the control group (group C); (2) the low-frequency group (group L); (3) the middle-frequency group (group M); (4)the high-frequency group (H). The rats in the group C were given intramuscular injection (im) of 0.9% saline. Im of dexamethasone (Dex) was 1 mg/(kg·time). Rats were given two times im a week in the group C, four times im a week in the group M, and six times im a week in the group H. Each rat was sacrificed on thirty days post-administration. Results (1)The body weight of rats gradually increased in the Ctrl group , however , the body weight of rats declined gradually during the experiment in the group L, M and H. The size of immune organs (spleen and thymus) significantly decreased in rats of the group L, M and H. (2)Compared with the group C, cell edema was changed in the heart, renal and lung morphological fatty degeneration in liver , atrophy in spleen , atrophy in lymphoid nodules , and cell edema in kidney tubular were observed. Conclusion GCs cause serious degradation in the thymus and atrophy of the spleen. Administration has different inhibitory effect on immune function; the high frequency will lead to strong inhibition.

Objective To explore the relevant factors of diabetic retinopathy(DR).Methods 400 patients with type 2 diabetes were selected,and the relevant factors with DR of type 2 diabetes were analyzed.Results The incidence of DR in type 2 diabetes was 49.0％.In type 2 diabetes when diabetes duration＞15 years,the incidence of DR was 84.7％,duration＜5-year incidence rate was 30.0％ respectively,there were significant differences(P＜0.05).Incidence rate in lower blood glucose group and poor glycemic control group were 38.1％ and 68.5％ respectively,and there was statistically difference(P＜0.05),and in normal blood pressure and well control group,the incidence rates were 44.1％ and 41.2％,which were significantly better than 80.0％ of poorly controlled hypertension group.Conclusion Duration of diabetes,glycemic control level,blood pressure,exercise,and regular schedule were related factors of DR.The most important thing of DR treatment and prevention was to control blood glucose.

Objective:To investigate if acupuncture has an inhibitory effect on fatty toxicity and its possible mechanism. Methods: Thirty-four patients with simple obesity were clinically treated with acupuncture for 3 courses. Before and after treatment, body mass index(BMI) and fat percentage(F%) were determined, and serum insulin and adiponectin were measured by enzyme linked immunoassay, blood lipid and sugar by biochemical colorimetry and eight kinds of free fatty acids(FFAs) by high performance liquid chromatography. Twenty normal persons were selected as a control. Results:The total efficacy rate was 88.2%. Acupuncture could increase the decreased insulin sensitivity index(ISI) in the patients(t=-5.103, P=0.000). The correlation of a decrease in F% with an increase in unsaturated fatty acid after acupuncture was of significance(r=0.402, P=0.019) and its correlation with an increase in the ratio between unsaturated fatty acid and saturated fatty acid was also of significance(r=0.348, P=0.044). The correlation between increases in high density lipoprotein and in eicosapentaenoic acid was of significance(r=0.352, P＝0.041). The correlation between a decrease in BMI and an increase in high density lipoprotein was of significance(r=0.357, P=0.038). Adiponectin level significantly rose after acupuncture (compared with pre-treatment, P=0.000). The correlation between a decrease in FFAs and an increase in adiponectin was of significance(r=-0.349, P=0.043). Conclusion: Acupuncture can lower the levels of free fatty acids in the patients and increase their sensitivity to insulin to inhibit the fatty toxicity. The inhibitory effect of acupuncture on fatty toxicity is somewhat related to a rise in adiponectin level.

Objective To evaluate the plasma D-dimer level in the patients of type 2 diabetes mellitus with hypertension and investigate their correlation.Methods Eighty-five subjects were divided into three groups according to clinical manifestation:control group:20 subjects ; type 2 diabetes mellitus group:21 subjects; type 2 diabetes mellitus combined with hypertension group:44 subjects.The level of plasma D-dimer was measured and the difference was compared between groups.The results were showed as mean ± sd,and the difference was compared using ANOVA Test ( SPSS13.0).Results The plasma D-dimer concentrations in normal control group was ( 102.15 ± 32.48 ) μg/L,in single type 2 diabetes mellitus was ( 148.62 ± 80.99 ) μg/L,while plasma concentrations in type 2 diabetes mellitus combined with hypertension was ( 206.28 ± 92.99 ) μg/L.plasma D-dimer concentration was higher in single type 2 diabetes mellitus than that in normal control cases( P ＜0.05) ;And plasma D-dimer concentration was also found increased in type 2 diabetes mellitus combined with hypertension when compared with control group (P ＜ 0.01 ) ;And there was also significant difference on plasma D-dimer concentration between single type 2 diabetes mellitus and type 2 diabetes mellitus combined with hypertension cases ( P ＜ 0.05 ).Conclusion The plasma levels of D-dimer was increased obviously in single type 2 diabetes mellitus and type 2 diabetes mellitus combined with hypertension,it may be related to the imbalance of coagulation and fibrinolytic system.Monitoring of plasma D-dimer concentration in type 2 diabetes and patients with hypertension may have important clinical implications for the prevention of thrombotic diseases.

Objective To explore the manifestations and diagnostic value of CT and MRI in gynecological acute abdomen.Methods CT and MRI features of 45 patients with gynecological acute abdomen proved by surgery were reviewed,including 17 ectopic pregnancy,10 ovarian cyst rupture,6 pedicle torsion of ovarian tumors,9 tubo-ovarian abscess and pelvic inflammation and 3 uterine perforation.31 cases underwent CT examination,14 cases underwent MRI examination and 39 cases underwent non-enhancement and enhancement scanning.Results In the 17 ectopic pregnancy cases,cystic structure surrounded by a thick wall or heterogeneous mass located in adnexal area was found,with 10 cases showing increased number of peripheral vessels penetrating into tumors.In the 10 cases with rupture of ovarian cyst, thick capsule wall was incomplete and cystic cavities collapsed in 7 lesions.In the 6 cases with pedicle torsion of ovarian tumors,irregular thickening of tumor pedicle were found in 4 cases,ovarian enlargement with surrounding follicles arrayed as fruit platter were found in 2 cases.In the 9 cases with tubo-ovarian abscess and pelvic inflammation,honeycomb-shaped lesions and multilocular changes were found in 6 cases and fallopian tube expanded like sausages in 5 cases.3 cases with uterine perforation exhibited intrauterine gas and fluid.Uterus with overflowed gas was found in 2 cases.One case had the thin and incomplete uterine wall.Conclusion CT and MRI can be used to confirm the causes of gynecological acute abdomen,and to comprehensively display the anatomical structures and pathological changes of pelvic tissues and organs.Therefore,CT and MRI are effective supplement means for the clinical diagnosis of gynecological acute abdomen.

Objective: To investigate clinical characteristics and treatment of phytophotodermatitis due to ingesting Chenopodium album. Methods: This study included 11 patients with phytophotodermatitis caused by ingesting Chenopodium album collected from Department of Dermatology, Affiliated Hospital of Jining Medical University from 2013 to 2017. The patients′ general information, clinical manifestations, laboratory test results, treatment and prognosis were retrospectively analyzed. Results: All the 11 patients were female, and their age ranged from 45 to 62 years. They all had a history of ingesting Chenopodium album and exposing to sunlight within 1 - 2 days prior to the disease onset. Clinical manifestations included symmetrically distributed, painful and pruritic, nonpitting, swelling erythema on the face and back of both hands and at sunexposed sites of forearms, with a tense and bright surface. Increased white blood cell counts were observed in 6 patients, and increased eosinophil counts in 1. All of the 11 patients were treated with systemic methylprednisolone, loratadine, ebastine, spironolactone, furosemide and omeprazole as well as topical agents, 2 also received human immunoglobulin treatment, and 3 were also treated with oral ibuprofen and codeine for painful lesions. Ten patients received obvious improvement and were discharged after 7 - 10 days of treatment, and no pigmentation or scars were observed after 1-year follow-up. Skin necrosis occurred on the back of both hands in 1 patient after 7-day treatment, and scars remained in the patient after follow-up of half a year. Conclusions Chenopodium album-induced phytophotodermatitis commonly manifests as swelling erythema on the exposed body sites. After confirmed diagnosis, Chenopodium album ingestation and sunlight exposure should be avoided, and timely antianaphylactic treatment should be considered to effectively control the disease.

The clinical data of 14 patients with niacin deficiency diagnosed and treated in Department of Dermatology, Affiliated Hospital of Jining Medical College from 2012 to 2021 were retrospectively analyzed. There were 11 males and 3 females aged 26-65 years. The etiological factors were alcoholism in 8 cases, gastrointestinal disease in 3 cases, medication history in 1 case, and unknown etiology in 2 cases.Patients had typical skin lesions, 1 case also had both digestive system and nervous system symptoms, and 3 cases had combined digestive system symptoms and 2 cases had neurological symptoms. All patients were systematically treated with oral nicotinamide and vitamin B complex, and also with topical drugs; and they all improved after 14-52 days of treatment. During regular follow-up, 2 cases of alcoholics and 1 case with diarrhea had recurrence. It is suggested that the typical clinical triad of niacin deficiency is uncommon, and the diagnosis is based on the medical history, clinical manifestations and relevant laboratory test, and the treatment with nicotinamide and vitamin B complex is usually effective; alcoholism is the main cause in male patients and is prone to recurrence.
