Objective To investigate the value of contrast enhanced ultrasound (CEUS) in diagnosing metastatic adrenal carcinoma. Methods Twenty two metastatic adrenal carcinoma lesions in 18 patients were examined using CEUS. The features and detected rate of gray scale and CEUS were analysed and compared. Results Fourteen lesions of metastatic adrenal carcinoma were detected by two dimensional ultrasonography(2DU), the detected rate of 2DU was 58. 3%. While 20 lesions were detected by CEUS, the detected rate was 83. 3%. There was a significant difference of detected rate between 2DU and CEUS (P<0.05). The adrenal metastatic carcinomas were enhanced rapidly with the peek intensity slightly low or same to the surrounding liver or renal parenchyma. The lesions number, size and range were clearly presented by CEUS. Conclusions CEUS can markedly improve detected rate of metastatic adrenal carcinoma compared with 2DU.

Objective To evaluate the effect of transitional care on the quality of life in patients with maintenance hemodialysis (MHD).Methods 101 MHD patients with symptoms of kidney ＜ 80 points were assigned into the interventional group (47 of 51 cases completed the study) and the control group (45 of 50 cases completed the study) by random number table method.The patients in the interventional group received transitional care for 6 months,while control group received routine care.The effects on function index,satisfaction index and clinical index were evaluated at the 3rd month and 6th month after intervention.Results 6 months after intervention,the scores of physical composite,mental composite,burden of kidney disease,symptoms/problems list,effects of kidney disease in the interventional group were 51.78±5.91,55.32±5.36,29.79±17.64,79.39±6.73,68.02±11.38,while the scores of the control group were 38.22±9.46,42.03±8.32,19.58±17.25,69.49±10.10,52.09±16.78,and the difference between the two groups was statistically significant (t=5.308-9.063,Z=-3.07,P ＜ 0.01).The scores of self-management behavior,health locus of control in the interventional group were 71.30-±5.42,25.74±2.42,while the scores of the control group were 65.0±8.74,22.47±3.97 (t=4.132,4.759,P ＜ 0.01).The nursing satisfaction in the interventional group scored 91.06±7.29,which was significantly higher than the control group scored 86.22±10.72 (Z=-2.45,P＜ 0.05).The level of serum phosphorus (PO4),Ca × PO4 products,parathormone (PTH) in the interventional group were (1.76±0.35) mmol/L,(51.02±10.04) mg2/dl2,464.56 ng/L,which were significanlty lower than (2.01±0.54) mmol/L,(57.41±17.38) mg2/dl2,625.78 ng/L in the control group (t=-2.691,-2.167,-2.000 in tum,P ＜ 0.01 or 0.05).Conclusions Transitional care achieves good effectiveness on the quality of life in patients with MHD.

Objective To evaluate the diagnostic value of shear wave elastography(SWE)and Breast Ima-ging Reporting and Data System -Ultrasonograpy(BI -RADS -US)in benign and malignant breast lesions.Methods 180 patients with pathological -confirmed benign and malignant breast lesions without any treatment were underwent ultrasonography scoring with BI -RADS and the quantitative elasticity parameters was measured by shear wave elastography 1week before operation.Pathological results were regarded as the gold standard,receiver operating characteristic curve(ROC)was used to determine cutoff values of quantitative parameters and diagnostic performance of two methods.Results Maximum elastic value(Emax)and mean elastic value(Emean)of benign breast lesions were (39.17 ±11.48)kPa and (21.56 ±9.68)kPa,which were significantly lower compared with the malignant breast lesions of (121.38 ±28.97)kPa and (62.92 ±18.49)kPa,respectively(t =23.668,P =0.000;t =18.194, P =0.000).Taking 43.79kPa and 65.15 kPa as the threshold of the Emean and Emax value,the sensitivity,specificity and accuracy of SWE were 92.59%,90.78% and 94.84%,respectively.The areas under the curve(AUC)of the SWE and BI -RADS -US were 0.942 and 0.883 (P =0.042).Conclusion SWE can improve the accuracy of ultrasonography in differentiation of benign from malignant breast lesions by quantitative elasticity parameters,which has important significance for clinical treatment.

Objective:To summarize the clinical characteristics, diagnosis and treatment of caspase recruitment domain-containing protein 9 (CARD9) gene deficiency associated invasive candidiasis, and report a novel mutation in CARD9 gene.Methods:The clinical characteristics, laboratory tests, treatment and the outcome of follow-up in a boy with invasive candidiasis were described. The boy′s main clinical manifestations were central nervous system infection and retroperitoneal mass. Whole-exome sequencing was performed and Sanger sequencing was verified to identify the CARD9 gene mutations in the patient and his parents. A literature search for “CARD9”and “invasive candidiasis”was conducted in PubMed, Wanfang and CNKI databases from their establishment to May 2020.Results:A 10-year-old boy suffered onset symptom of chronic diarrhea, which lasted for two months. The symptom was followed by progressive neurological symptoms such as headache, vomiting, seizures and disorder of consciousness. His unusual medical history was absent. Candida albicans were cultured several times in cerebrospinal fluid and blood, and yeast-like fungi were found in the stool high power field of vision. Cerebral magnetic resonance imaging indicated obstructive hydrocephalus and abdominal CT scan showed retroperitoneal mass and thickening of the intestinal wall. The whole-exome sequencing analyses of blood samples from the boy and his parents were performed. The results showed that there was a homozygous mutation of c.952-12_956delinsAG in the CARD9 gene, which was an unreported pathogenic mutation. This was confirmed by Sanger sequencing. There was no significant relief from intravenous combined antifungal medications. After lateral ventricular drainage surgery and injection of amphotericin B into the lateral ventricle, improvement of clinical symptoms and cerebral spinal fluid abnormalities was observed after nine weeks, and the retroperitoneal mass shrank. At follow-up after four-month oral combined antifungal medications, the child had no complaint except fatigue. However, cerebral spinal fluid analysis showed increased protein level and decreased glucose. Persistent hydrocephalus and periventricular white matter abnormal signals were revealed on the brain magnetic resonance imaging and the smaller retroperitoneal mass than before on the abdominal CT scan. In addition to this case, totally 21 cases with CARD9 gene deficiency associated invasive candidiasis have been reported worldwide, most of which featured central nervous system infections.Conclusions:CARD9 gene deficiency is an autosomal recessive primary immunodeficiency that confers human susceptibility to fungal disease. The associated invasive candidiasis often affects the central nervous system and makes the patient severely ill. Adequate systemic antifungal therapies should be given, and patients with hydrocephalus need surgical treatment. A novel mutation is reported that expands the variant diversity of CARD9 gene. For patients with unexplained invasive candidiasis, including those without a history of previous recurrent infection, genetic testing is recommended for primary immunodeficiency including CARD9 gene deficiency.

Objective:To investigate the infection status of Yersinia in the main host animals of plague in Xiahe and Luqu counties, the Himalayan marmot plague foci of Gansu Province, and to provide a basis for exploring the epidemic status of plague in these foci. Methods:Samples of the ileocecal region and contents, pharyngeal swabs (or tongue roots), and blood of the main host animals of plague in Xiahe County and Luqu County where the plague were active in the 1950s and 1960s were collected from 2014 to 2018. The Yersinia isolation, virulence determination and F1 antibody detection were performed, respectively. Results:Totally 24 strains of Yersinia were detected in 958 samples of ileocecal region and contents with a bacterial detection rate of 2.51%, which were 13 strains of Yersinia enterocolitia (Y.e), 1 strain of Yersinia kristensenii (Y.k), 2 strains of Yersinia frederiksenii/ intermedia (Y.f/i), 6 strains of Yersinia intermedia (Y.i), 1 strain of Yersinia aldouae (Y.a) and 1 strain of Yersinia massiliensis (Y.m). Totally 19 strains of Yersinia were detected in 958 samples of pharyngeal swabs (or tongue roots), and the detection rate was 1.98%, which were 8 strains of Y.e, 1 strain of Yersinia pseudotuberculosis (Y.p), 4 strains of Y.k, 1 strain of Y.f/i, 4 strains of Y.i, and 1 strain of Yersinia ruckeri (Y.r). The virulence types of 21 strains of Y.e were ail -ystA -ystB +yadA -virF -rfbc -, ail -ystA -ystB -yadA -virF -rfbc -, respectively, accounting for 9.52% (2/21) and 90.48% (19/21), none were pathogenic. The results of F1 antibody in 1 079 serum samples were all negative. Conclusions:Yersinia are widely found in the pharynx and intestines of the main host animals of plague in Xiahe and Luqu counties, and the Y.e detected are all non-pathogenic strains. The results of this investigation can provide clues for further study on the preservation of Yersinia pestis in host animals and their living environment.

Objective:To observe the clinical characteristics of paroxysmal sympathetic hyperactivity (PSH) in children with acute brain injury.Methods:The clinical characteristics, hospitalization data, hospitalization cost, and prognoses of 40 children with acute brain injury admitted to our hospital from June 2018 to June 2020 were retrospectively summarized. In addition, the differences of above data between children with PSH and children without PSH were comparatively analyzed.Results:Nine children were with PSH, with an incidence of 22.5%; five were with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis, two were with acute necrotizing encephalopathy, and two were with severe viral encephalitis. Thirty-one children were without PSH; five were with metabolic encephalopathy, 19 were with viral encephalitis, three were with anti-NMDAR encephalitis, one was with acute cerebral infarction, one was with primary central nervous system lymphoma, one was with acute necrotizing encephalopathy, and one was with severe closed head injury. The patients with PSH had significantly higher proportion of patients with anti-NMDAR encephalitis, significantly higher hospitalization cost, statistically longer duration of disorder of consciousness and hospital stays, and significantly lower Glasgow coma scale (GCS) scores at discharge than the patients without PSH ( P<0.05). Conclusion:PSH is common in children with acute brain injury; PSH can lead to a long period of disorders of consciousness, long hospital stays, high hospitalization cost, and poor prognosis, which causes an increase in family and social burdens.

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.

Objective: To explore the application value of B-ultrasound examination in gynecological acute abdomen. Methods: From October 2015 to October 2017, 150 patients with suspected gynecological acute abdomen were selected in the People's Hospital of Lishui.The effect of B-ultrasound examination in diagnosis of gynecological acute abdomen was analyzed. Results: The sensitivity, specificity and total accuracy of abdominal ultrasound in the diagnosis of gynecological acute abdomen were 75.00%(99/132), 44.44%(8/18) and 71.33%(107/150), respectively.The sensitivity, specificity and total accuracy of transvaginal ultrasound in the diagnosis of gynecological acute abdomen were 87.12%(115/132), 72.22%(13/18) and 85.33%(128/150), respectively.The sensitivity, specificity and total accuracy of abdominal combined with transvaginal ultrasonography in the diagnosis of gynecological acute abdomen were 98.48%(130/132), 94.44%(17/18) and 98.00%(147/150), respectively.The sensitivity, specificity and total accuracy of abdominal combined with transvaginal ultrasound in the diagnosis of gynecological acute abdomen were significantly higher than those of abdominal ultrasound and transvaginal ultrasound(χ²=8.658, 10.699, 9.075, all P<0.05). The diagnosis of acute pelvic inflammation, ectopic pregnancy, rupture of luteal cyst and torsion of ovarian cyst by abdominal combined with transvaginal ultrasound was better than abdominal ultrasound(χ²=13.748, 5.984, 13.524, 6.874, all P<0.05). Conclusion Abdominal ultrasound and transvaginal ultrasound can be used to diagnose gynecological acute abdomen.However, abdominal combined with vaginal ultrasound is more effective in the diagnosis of gynecological acute abdomen, and it can effectively improve the accuracy of diagnosis.

Objective: To explore the application value of B-mode ultrasound combined with real-time color doppler ultrasound in percutaneous nephrolithotomy and provide guidance for clinical application. Methods: A total of 150 patients underwent percutaneous nephrolithotomy from December 2015 to December 2017 in the People's Hospital of Lishui were selected.According to different ultrasound guidance methods, the patients were divided into two groups.The single group(70 cases) received B-guided puncture.In the combined group(80 cases), B-ultrasound combined with real-time color doppler ultrasound-guided puncture was applied.The incidence of complications and the success rate of lithotomy were compared between the two groups.The changes in renal artery blood flow parameters[end diastolic velocity(EDV), peak systolic velocity(PSV) and resistance index(RI)] before and after surgery in the combined group were observed. Results: The incidence of complications in the combined group was 2.50%(2/80), which was lower than that in the single group[14.29%(10/70)](χ²=7.046, P<0.05). The success rate of stone extraction in the combined group was 98.75%(79/80), which was higher than that in the single group[85.71%(60/70)](χ²=9.336, P<0.01). The EDV and PSV of the renal interlobar arteries of the combined group before and after surgery had statistically significant differences (t=3.794, 5.385, all P<0.05), but the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal segment arteries in the combined group before and after surgery had statistically significant differences (t=4.535, 4.884, all P<0.05), while the RI had no statistically significant difference (P>0.05). The EDV and PSV of renal aorta of the combined group before and after surgery showed no statistically significant differences (all P>0.05), while the RI showed statistically significant difference (t=4.360, P<0.05). Conclusion B-mode ultrasound combined with real-time color doppler ultrasound guidance for percutaneous nephrolithotomy can help reduce the incidence of complications and improve the success rate of stone extraction to a certain extent.
