Objective To discuss the ultrasonographic characteristics of schistosomal appendicitis lesions. Methods Among the patients with schistosomal hepatopathy who were discovered by Color Doppler ultrasound in Huzhou Central Hospital from January 2012 to December 2015,50 cases with clear history of schistosomiasis and treatment were chosen as a schistosom?al hepatopathy group,meanwhile,50 normal people,who came from non?endemic areas,without schistosomal hepatopathy and schistosomiasis history were chosen as a control group. The two groups were examined by ultrasound scan of the appendix ,and the data of the largest diameter of the appendix and the thickness of the appendix wall were collected,and the sonographic char?acteristics of their appendixes,such as whether the echo of the appendix wall was even or not,were observed. Results The minimum internal diameter of the appendix cavity and the thickness of the appendix wall of the schistosomal hepatopathy group were(2.090 ± 0.790)mm and(1.332 ± 0.313)mm ,respectively,the former was significantly narrower than that of the control group,while the latter was significantly thicker than that of the control group(t=2.647,-4.526,respectively,both P<0.05). The proportions of those with inhomogeneous echo,indistinctness structure,uneven thickening of the appendix wall,as well as having intestinal contents in the appendix cavity in the schistosomal hepatopathy group were higher than those in the control group(χ2=12.000,18.537,24.008,4.244,respectively,all P<0.05). Conclusions Schistosomal appendicitis lesions have obvious ultrasonographic characteristics under ultrasound. Ultrasound can play an important role in judging whether the appen?dix of schistosomiasis patients is involved and discovering the lesion of appendix early.

ObjectiveTo explore the effect of osteoclasts and osteoprotegerin/receptor activator of nuclear factor-kappa B ligand (OPG/RANKL) system on bone destruction of psoriatic arthritis.MethodsThe peripheral blood mononuclear cells from 41 psoriatic arthritis (PsA) patients,20 osteoarthritis (OA) patients and 24 healthy controls were cultured to become osteoclasts.After 14 days,cytochemistry method was used to detect tartrate-resistant acid phosphatase (TRAP) expression.At the same time,enzyme-linked immuno sorbent assay(ELISA) was used to measure the levels of serum OPG and RNAKL for all cases.At the same time,the clinical and laboratory examinations of the PsA were collected.Statistical analysis was conducted with one-way ANOVA and Spearman's correlation.ResultsSignificantly higher OC production was observed in the peripheral blood of PsA patients[(17.7±4.8)/view field] than that of the healthy controls[(6.4±1.6)/view field] and OA patients [(6.5±l.6)/view field].The levels of RANKL were significantly higher in PsA patients [(178±38) pg/ml] than those in the other two groups [(32±4) pg/ml and (67±17) pg/ml].There was significant difference between the PsA group with bone destruction and without destruction in the levels of OC and RANKL [(17.6±0.9) /view vs(7.9±1.3) /view and(199±72) pg/ml vs(128±44) pg/ml,P＜0.01].Imaging scores was positively correlated with the levels of OC and RANKL in PsA patients (P＜0.05).ConclusionIn PsA,there are significantly more OC and higher RANKL in the peripheral blood than those of the controls.The high levels of OC and RANKL are closely related with bone destruction.OC and RANKL are useful in identifying bone destruction.

Objective To solve the difficulty of intubation of nasojejunal feeding tube under digital subtraction angiography (DSA) system when conventional methods were failed.Methods Seventy-one patients who failed to place the nasojejunal feeding tube by single guide wire under DSA conventional methods.With the methods of decreasing the stomach volume,changing the body posi-tion,and using a catheter or gastrointestinal motility,the nasojejunal feeding tube was placed into the proper position (more than 30cm far away from Treitz or gastrointestinal anastomosis).Results All the procedures were successfully accomplished.No compli-cations,such as throat damage,abdominal pain,perforation and hemorrhage of digestive tract were found.The mean duration under DSA was four minutes (2-7min).Conclusion With the help of various methods above,we can improve the success rate of intuba-tion and reduce the duration of the nasojejunal feeding tube placement,when conventional methods were failed.

Objective To observe the bone metabolism of psoriatic arthritis (PsA) and investigate the roles of some bone metabolism markers such as tartrate-resistant acid phosphatase 5b (TRACP5),C-terminal telopeptide of collagen-Ⅰ (CTX-Ⅰ) and BALP in PsA patients with bone destructions.Methods Sixty-five cases of psoriatic arthritis,30 cases of psoriasis and 30 cases of healthy people were enrolled.Bone mineral densities of lumbar spines and the left femoral necks were measured for all PsA patients using dual energy X-ray absorptiometry.The Serum levels of TRACP5b,CTX-Ⅰ,BALP of healthy controls,Ps and PsA patients were measured.The PsA group was further divided into bone destruction group and none bone destruction group by image datasets.The levels of TRACP5b,CTX-Ⅰ,BALP,PsAJAI,ESR and CRP from each group were detected.Mann-Whitney and x2 test were used for statistic analysis.Results TRACP5b levels of the healthy controls,Ps and PsA patients were (0.9±0.4),(0.7±0.5) and (2.0±1.4) U/L respectively,and were significantly higher in the PsA patients than those of the other two groups (Z=-3.698,-3.638; P＜0.05).The CTX-Ⅰ levels of these three groups were (0.9±0.8),(0.6±0.7) and (2.6±1.8) ng/ml respectively,and were also dramatically higher in the PsA patients than the other two groups (Z=-5.262,-5.734; P＜0.05).BALP levels of each group were (22±4),(22±4) and (25±7) U/L,and were also evidently higher in the PsA patients than patients in the other two groups (Z=-2.214,-2.000; P＜0.05).Meanwhile,the levels of TRACP5b [(2.6±1.4) U/L],CTX-Ⅰ [(3.1±1.8) ng/ml] and BALP [(26±7) U/L] were significantly higher in bone destruction group than those in the none bone destruction group [(1.2±1.0) U/L,(1.9±1.6) ng/ml,(23±6) U/L,Z=-3.544,-3.429,-2.083; P＜0.05].Conclusion The high levels of TRACP5b,CTX-Ⅰ and BALP in PsA indicate that there is bone metabolism imbalances in PsA.And the high levels of TRACP5b,CTX-Ⅰ and BALP in the bone destruction group suggest that the rises of TRACP5,CTX-Ⅰ and BALP levels may be related with bone erosions.

Objective To explore the clinical characteristics and prognosis of congenital pulmonary artery sling (PAS) in children. MethodsThe clinical data of 38 children diagnosed with PAS during June 2009 and February 2015 were retrospectively analyzed. ResultsIn 38 PAS children, 35 cases (89.47%) were hospitalized for varying degrees of respiratory manifestations with recurrent cough (89.47%) and wheezing (84.21%) being the most common. The remaining 3 cases were found abnormal in routine preoperative examination and the diagnosis was confirmed after further examination. All 38 children were performed computer tomography angiography (CTA). Thirty-seven cases were diagnosed of PAS and diagnostic rate was 97.37%. One case was suspected of pulmonary dysplasia and diagnosed of PAS after operation. Twenty-six children received surgical treatment, of whom 25 children had pulmonary artery reconstruction (LPA). Seven children died during/after operation and 18 survived. The remaining 12 children received non-surgical treatment, of whom 9 died and 3 survived.ConclusionCardiac uhrasonography may reveal PAS in the early stage, while CTA is the best method for conifrmed diagnosis. LPA reconstruction is an important means of relieving left pulmonary artery oppression.

Objective To evaluate the effectiveness of psychological health intervention in the elderly urban residents living on minimum subsistence allowances, and to search for a suitable psychological health intervention strategy. Methods The 112 elderly persons living on minimum subsistence allowances in Xuzhou were selected by stratified cluster sampling, and they were matched with 112 controls. The elderly persons living on minimum subsistence allowances were divided into intervention group and control group. A general intervention based on community involved psychological health and care lecture, psychodrama treatment and psychological consultancy was made on the intervention. The SCL-90 was used to evaluate the psychological health status and effectiveness of psychological health intervention. Results The elderly persons living on minimum subsistence allowances had higher SCL-90 scores compared with other residents, and their psychological health status was serious. After the psychological health intervention, the SCL-90 scores were all lower in intervention group than in control group [ interpersonal relationship sensitiveness: (1.13 ± 0. 39) vs.(1.26±0.26), t=2.12, P=0.04; gloom: (1.23±0.66) vs. (1.43±0.24), t=2.08, P=0.04;anxiety: (1. 18±0.50) vs. (1.38±0.34), t=2.17, P=0.03; hostility: (1.24±0.49) vs. (1.40±0.28), t=2.03, P=0.04; other factor: (1. 31±0.56) vs. (1.49±0.31), t=2.04, P=0.04; total score: (115.89± 17.21) vs. (122.64± 10.41), t=2.42, P=0.02]. Conclusions The psychological health parameters are improved by psychological health intervention.

Objective To analyze the characteristics of serum vancomycin concentrations and its clinical therapeutic effects. Methods Serum vancomycin concentrations of 59 children diagnosed with severe Gram positive cocci pneumonia and treated with vancomycin were retrospectively analyzed. Vancomycin concentrations, biochemical values and disease status of patients were analyzed. Results The serum vancomycin concentrations of severe Gram positive cocci pneumonia children accompanied by acyanotic congenital heart disease was significantly higher than those without congenital heart disease, ( 12 . 12 mg/L vs 7 . 76 mg/L, P=0 . 008 ). The therapeutic effect of 40-60 mg/(kg·d) dosage group was signiifcantly higher than that of?60 mg/(kg·d) dosage group. Acute liver function damage and moderate/severe anemia may be risk factors for poor therapeutic effects to severe Gram positive cocci pneumonia children (P?

OBJECTIVE: To investigate the difference of tumor formation in different mouse strains bearing patient-derived xenograft of esophageal squamous cell carcinoma(ESCC) and establish a better animal model for preclinical study of individualized treatment of ESCC. METHODS: The tumor tissues collected from 22 ESCC patients were used to establish tumor-bearing mouse models in B-NDG (NSG) mice and BALB/c nude mice. The tumor formation rate and tumor formation time were compared between the two mouse models, and HE staining, immunohistochemistry and genome sequencing were carried out to assess the consistency between transplanted tumor tissues in the models and patient-derived tumor tissues. RESULTS: The tumor-bearing models were established successfully in both NSG mice (50%, 11/22) and BALB/c nude mice (18.18%, 4/22). The average tumor formation time was significantly shorter in NSG mice than in BALB/c nude mice (75.95 91.67 days, < 0.001). In both of the mouse models, the transplanted tumors maintained morphological characteristics identical to those of patient-derived ESCC tumors. Genetic analysis showed that the xenografts in NSG mice had a greater genetic similarity to the patients' tumors than those in BALB/c nude mice ( < 0.0001). CONCLUSIONS Mouse models bearing xenografts of patient-derived ESCC can be successfully established in both NSG mice and BALB/c nude mice, but the models in the former mouse strain can be more reliable.
