Objective To investigate the relationship among 18 F-fluorodexyglucose (FDG) PET, pattern of lipiodol retention CT and serum ?-fetoprotein(AFP) in evaluating the effect of transcatheter arterial chemoembolization(TACE) for hepatocellular carcinoma (HCC). Methods TACE was performed in thirty-five patients with HCC. 18 F-FDG PET and lipiodol-CT examination were performed after TACE, and thus the patterns of lipiodol retention, and the tumor necrosis rates semi-quantitatively by 18 F-FDG PET were obtained with simultaneous calculation of the decrease percentage of serum AFP before and after TACE. Results The patterns of lipiodol retention were divided into four types; A. dense type (n=12), B. rarity type (n=13), C. scattering type (n=7) and D. empty type (n=3). The positive correlation between the tumor necrosis rate (7%～95%) and the decrease percentage of AFP(0～100%) were found (r=0.761 P

The concentrations of prostaglandin in high mobility group box-1 ( HMGB1 ) and highsensitive C-reactive protein (Hs-CRP) in serum and peritoneal fluid were detected in 76 patients with endometriosis (study group) and 30 patients without endometriosis (ovary cysts or uterine myoma, as control group). The peritoneal fluids were collected during laparoscopic operation, and the serum samples were collected before surgery. The HMGB1 and Hs-CRP concentrations in serum and peritoneal fluid of study group were significantly higher than those of control group, ( 8. 2 ± 0. 8) mg/L vs. (2. 1 ±. 0. 2) mg/L、 ( 14. 4 ±3.0) mg/L vs. (4.5 ±2.3) mg/L (both P＜0. 01);HMGB1 and Hs-CRP levels in serum and peritoneal fluid of stage Ⅲ-Ⅳ endometriosis were significantly higher than those of stage Ⅰ-Ⅱ, ( 9. 2 ± 0. 8) mg/L vs.(6.7 ±0.7) mg/L,(18.7 ±2.9) mg/L vs. (11.2 ±2. 8) mg/L,(6.5 ±0.6) mg/L vs. (3.4 ±0.5) mg/L,(8.4 ±2.7) mg/L vs. (5.4 ±2.4) mg/L (all P ＜0.05). The concentrations of HMGB1 were positively correlated with Hs-CRP in endometriosis group (r =0. 72, P ＜0. 01 ). The results indicate that concentrations of HMGB1 and Hs-CRP may be of value in assessing the severity of endometrosis.

Objective To explore the cause and the interventional treatment of restenosis after percutaneous transhepatic biliary stent.Methods 20 patients with biliary restenosis after percutaneous transhepatic biliary stent placement were collected.According to drainage volume from biliary tract and degree of amelioration of jaundice,post-operation hepatic function,blood,urine and stool routines,ultrasound,CT scan and cholangiography were performed to determine the nature and location of biliary restenosis,and then all cases underwent recanalization with intervention method by the exteriorized drainage tube approach.The China-made nickel-titanium alloy stents with diameter of 10 mm and length ranged from 40 mm to 80 mm were used.Results The biliary restenosis occurred in mid-inferior segment of common bile duct in 9 patients, common hepatic duct in 7 patients and hepatic porta in 4 patients. As regarding the causes of restenosis included tumor compression in 9 cases, angulation in upper segment of stent in 3 cases, obstruction in stent by bile, food or clot in 4 cases, cholangitic stenosis in 2 cases and granulation proliferation in 2 cases.The obstruction in all cases was relived by extraction through drainage tube, drug irrigation,dredging by wire, balloon dialtion or stent replacement, so that the total survival rate was beyond 6 months.Conclusion After percutaneous transhepatic biliary stent placement in treating the malignant biliary obstruction,the rate of biliary restenosis is still high,which should be attached importance to.

Objective The study was to investigate the spectrum and incidence of the hot-spot deafness gene mutations from non-syndromic hearing loss(NSHL)in Guizhou province.Methods Genomic DNAs of 356 patients of NSHI in Guizhou were obtained from peripheral blood and a deafness gene test chip was used to screen nine hot spot mutation in the gene GJB2,SLC26A4,GJB3 and mitochondria 12SrRNA.Results Eighty-eight (24.72%)out of 356 patients were found carrying at least one pathogenic gene mutation.Among them,40 patients with the GJB2 mutations were found(11.24%),including 19 cases(5.34%)of homozygous matutions,5 cases(1.40%)of com-pound heterozygous mutations,and 15 cases(4.21%)of single heterozygous mutations.Twenty-nine patients with the SLC26A4 mutations were found (8.15%),including 9 cases(2.53%)of homozygous mutations and 19 cases (5.34%)of single heterozygous mutations.Homogenic mitochondrial 12SrRNA 1555A>G mutations were in 10 patients(2.81%)and 1494C>T mutations in 10 patients (0.56%),and heterogeneous mitochondrial 12SrRNA 1555A>G mutations in 7 patients(1.97%).GJB3 gene c.538C>T heterozygous mutations was found in 1 patients. Conclusion The mutations of GJB2 and SLC26A4 gene are two major pathogenic genes for patients with NSHL in Guizhou province.Our study provides a theoretical basis for the early diagnosis,genetic counseling and treatment of deafness.

Objective:To evaluate the relationship betweenparacardial adipose tissue (PAT) volume, body mass index (BMI) and severe coronary artery stenosis in young people by quantitative measurement of 256-slice spiral CT.
Methods: A total of 150 patients younger than 45 years and received coronary angiography (CAG) in our hospital were divided into 2 groups:Lesion group, the patients with severe main coronary branch stenosis and Control group, patients with normal coronary artery. n=75 in each group. The height, body weight and BMI were recorded in all patients;imaging data was uploaded to the workstation to calculate the volumes ofepicardiumadipose tissue (EAT) volume,pericardial outsideadipose tissue volume and PAT volume, the correlation among 3 parameters were analyzed respectively.
Results:Compared with Control group, Lesion group had increased BMI (28.169±2.203) kg/m2 vs (24.960±3.041) kg/m2 and PAT volume (178.676±3.041) ml vs (99.0616±3.041) ml, all P<0.05. Compared with Control group,no matter male or female, Lesion group had larger PAT volume, P<0.01.EAT volume was related to pericardial outside adipose tissue volume (r=0.837, P<0.001) and PAT volume (r=0.971, P<0.001);pericardial outside adipose tissue volume was related to PAT volume (r=0.944, P<0.001).
Conclusion:PAT volume and BMI were obviously correlated to severe coronary artery stenosis in young people.

Hemodynamics is a discipline that studies the effects of blood flow,blood flow volume and other factors on the arterial wall.Intracranial aneurysm is the main cause of death due to non-traumatic subarachnoid hemonhage,which has brought a heavy burden on society.Therefore,it is very important to make an intensive study of the pathogenesis of aneurysm.With the development of medical imaging technology and fluid mechanics software in recent years,it becomes possible to make the precise and scientific studies of the hemodynamics of intracranial aneurysms.In this paper,the hemodynamic factors inducing the formation of intracranial aneurysm that are proposed by medical experts at home and abroad are reviewed,and the hemodynamic mechanism is discussed.

Objective To describe the change of symptoms and quality of life among nasopharyngeal carcinoma patients who undergo radiotherapy, and analyze the correlation between them.Methods A total of 218 nasopharyngeal carcinoma patients who received radiotherapy were included by convenient sampling method and they were asked to finish the questionnaire of general information, Chinese Version of the M.D. Anderson Symptom Inventory(MDASI-C) and Quality of Life Instruments for Cancer Patients-Head and Neck (QLICP-HN) at five time points, which were beginning, intermediate (the volume of radiotherapy at 36-40 Gy), end of radiotherapy, three months and six months after radiotherapy.Results The severity of symptoms at five time points were (1.86±1.75),(3.20±1.75),(3.59±1.81),(0.65±0.59) and (0.52±0.50), presenting decreased gradually first, and then alleviated. The score of symptom severity at five time points were significantly different (F=182.86,P<0.05). Fatigue, appetite loss and dry mouth were the most sever and high-incidence symptoms during and within six months after radiotherapy. The quality scores of life were (65.39±10.90),(58.78±8.77),(57.82±9.20),(79.76±5.75) and( 76.79±4.78) at five time points, representing the same trend as the scores of symptom, and the difference were statistically significan(t F=129.75,P< 0.05). Spearman correlation analysissuggested that there were negative correlation between severity of symptoms and total score of quality of life (P < 0.05). Conclusions The symptoms of nasopharyngeal carcinoma patients exacerbates with dose of radiotherapy increase, and the quality of life is also decreased. Although most of symptoms disappear within six months after radiotherapy, fatigue, appetite loss and dry mouth persisted and influence patients' quality of life.Nurses should pay attention to patients' symptoms when they stay at hospital as well as discharged, and intervention is necessary to improve their quality of life.

Objective:To integrate the best evidence of non-drug intervention of urinary incontinence in elderly women and to formulate practical recommendations.Methods:In this systematic review study, using “elderly woman”,“urinary incontinence”,“bladder training”,“pelvic floor muscle training”,“enuresis”,“leakage of urine” as the key words, the 6S evidence resource pyramid model was used to search in British Medical Journal best practice, Uptodate, World Health Organization, Guidelines International Network, National Institute for Health and Care Excellence, Chinese Medical Association, Scottish Intercollegiate Guideline Network, Registered Nurses Association of Ontario, Cochrane Library, The Joanna Briggs Institute (JBI), New Zealand Guidelines Group, Polish Society of Gynecologists and Obstetricians, PubMed, Embase, Medline, Web of Science, SinoMed, China National Knowledge Infrastructure, WanFang Data, etc. The evidence retrieved included evidence-based knowledge base resources, clinical practice guidelines, expert consensus, systematic review, etc. Data were retrieved from January 1, 2017 to May 1, 2022, and collated from May 2, 2022 to May 25, 2022. Two researchers independently evaluated the quality of literature and extracted data using the AGREE Ⅱ and JBI evidence-based health care center assessment tools. The JBI evidence-based health care center′s evidence pre-rating system and evidence recommendation rating system were applied to rank the evidence; and under the guidance of the evidence structure of JBI, the strength of evidence recommendation was determined and the best evidence was extracted and summarized in combination with the study group discussion and expert opinion.Results:A total of 9 articles were retrieved, including 7 guidelines and 2 systematic reviews; and 6 guidelines were classified as Grade A and 1 as grade B; both 2 systematic reviews were rated as Grade A; 84% (27/32) of the items were evaluated as “Yes”. Evidence were summarized as 34 pieces of best evidence from 6 dimensions, including “overall recommendation, evaluation of type and degree of urinary incontinence, lifestyle change, behavioral therapy, prevention of precipitating factors, intervention in special population”; the flow chart of screening, evaluation, special symptoms, life style and behavior therapy was combed, and the practical suggestions were formed.Conclusions:The overall quality of the literature on non-drug intervention of urinary incontinence in elderly women is high, and the level of evidence is high. Early identification of urinary incontinence types and assessment of disease severity, lifestyle changes, avoidance of predisposing factors and behavioral therapy are the key to non-drug treatment of urinary incontinence in those patients.

Objective:To analyze ultrasonographic manifestations and genetic etiology of nine fetuses with 7q11.23 duplication syndrome.Methods:Ultrasonographic finding, pregnancy outcome and follow-up of nine fetuses detected at the Prenatal Diagnosis Center of the Third Affiliated Hospital of Zhengzhou University from January 2017 to December 2021 were retrospectively analyzed.Results:The fetuses were found to harbor a duplication in the 7q11.23 region by chromosomal microarray analysis (CMA). Among these, five had shown ventriculomegaly, including four syndromic and one non-syndromic. For the remainders, one had ventricular septal defect and mild tricuspid regurgitation, one had echogenic intracardiac focus, whilst another two were normal. Five couples had accepted parental verification, and the results confirmed that the 7q11.23 duplication carried by their fetuses were de novo in origin. Following genetic counseling, seven couples had opted to terminate their pregnancies. Two fetuses were delivered at full term, and follow-up had found no abnormalities. Conclusion:Prenatal ultrasonographic manifestations of fetuses with 7q11.23 duplication syndrome are variable. CMA can provide assistance for their diagnosis and genetic counseling.
