Objective Stereotactic body radiotherapy(SBRT)and radiofrequency ablation(RFA)are primary treatments for hepatocellular carcinoma(HCC)at present.However,the effect of these treatments in clinical trails are rather controversial.The purpose of this paper is to conduct a meta-analysis on the clinical effect and related complications of SBRT and RFA for HCC.Methods A computerized retrieval of academic papers concerning the treatment effect of SBRT and RFA for HCC from the databases of PubMed,Embase,Cochrane Library,Scopus,Web of Science,CBM,CNKI,Wanfang database,VIP was conducted.The retrieval time period was from the establishment of the database to June 2022.Stata14.0 software was used to make meta-analysis.Results A total of 14 retrospective studies including 6 806 patients were included in this analysis.The results of combined hazard ratio(HR)based on overall survival(OS)showed that the OS rate of SBRT was lower than that of RFA(HR=1.25,95％CI=1.10-1.43,12=0％,P=0.000 9),while the results of combined HR of local control(LC)rate indicated that SBRT had a better therapeutic effect(HR=0.61,95％CI=0.47-0.78,I2=0％,P=0.000 1).Subgroup analysis revealed that the combined HR of LC rate favored the performance of SBRT for patients with tumor diameter larger than 2 cm(HR=2.64,95％CI=1.56-4.48,I=0％,P=0.000 3).No statistically significant difference in the incidence of late serious adverse reactions existed between SBRTgroup and RFA group(OR=1.01,95％CI=0.59-1.73,I2=30％,P=0.97).Conclusion SBRT is superior to RFA in controlling local HCC lesions,especially in patients whose tumor diameter is larger than 2 cm,although it does not show certain advantages in the survival benefit.(J Intervent Radiol,2023,32:1233-1241)

Objective:To analyze the relationship of hepatic transit time and portal vein pressure in the patients with portal hypertension and esophagogastric varices, and to clarify its clinical significance.Methods:A total of50hospitalized patients underwent esophagogastric venous embolization due to portal hypertension and esophagogastric varices were selected as observation group, and 50patients without history of liver disease and clinical manifestations of liver disease (hospitalized or out-patient) were selected as control group, All patients underwent liver contrast enhanced ultrasound.The free portal pressure (FPP) was measured by ultrasound guided portal vein puncture for operating pathways in the patients in observation group.The hepatic artery-hepatic vein transit time (HA-HVTT) , the hepatic portal vein-hepatic vein transit time (PV-HVTT) , the liver parenchymahepatic vein transit time (PA-HVTT) of the patients were compared between two groups.The correlations between HA-HVTT, PV-HVTT, PA-HVTT and FPP of the patients in observation group were analyzed.Results:The HA-HVTT, PV-HVTT and PA-HVTT of the patients in observation group were significantly shorter than those in control group (t=5.078, P＜0.01;t=12.163, P＜0.01;t=2.649, P＜0.01) .The HA-HVTT, PV-HVTT and PA-HVTT had negative correlations with FPP in observation group (r=-0.799, P＜0.01;r=-0.554, P＜0.01;r=-0.735, P＜0.01) .The linear relationship between HA-HVTT and FPP was Y=-0.410X+7.254;the linear relationship between PV-HVTT and FPP was Y=-0.355X+4.983;the linear relationship between PA-HVTT and FPP was Y=-0.566X+4.997.Conclusion:Liver transit time can be used as an effective index to judge the portal vein pressure, and it can provide the theroretical basis for the diagnosis and treatment of portal hypertension in the patients.

Decision on mode of delivery (MOD) is a process involved by both clients and health care providers, based on specific clinical situations and women′s values. To help each woman obtain the best MOD is crucial for obstetric health professionals to provide women-centered high quality of care. There is a steep upward trend in cesarean sections in China due to the introduced advanced technologies, overused antenatal monitoring methods, flexible indications for cesarean sections, delayed childbearing ages and people′s misconceptions, etc.. Recently the conditional and comprehensive two-child policy have been implemented in China, which might initiate changes in fertility and birth intentions of many families, and in subsequent decisions on MOD. This review illustrates the pros and cons of MOD, decision process on MOD, influencing factors and strategies to promote decision on MOD, in order for the obstetric professionals to provide evidence-based best care for women and their families in the process of decision-making.

Objective To observe the curative effect of 17β-estradiol on idiopathic ventricular arrhythmia (IVA) during peri-menopausal period and explore the association with IP3/Ryn expression of receptor-regulated calcium pool. Methods 32 cases IVA during peri-menopausal period (IVA group) and 32 cases healthy women during peri-menopausal period of the same levels of age (normal control group) were selected. The IVA group received oral 17β-estradiol for 2 months. The count of arrhythmia in IVA group was recorded, the IP3/Ryn 2 expression pre- and post-treatment in IVA group and normal control group were detected. Results Compared with pre-treatment, 17β-estradiol significantly reduced the occurrence of IVA (P<0.05). Compared with pre-treatment, 17β-estradiol significantly reduced IP3 expression(P<0.05), while there was no significant difference compared with normal control group. 17β-estradiol had no significant effect on Ryn 2 expression. Conclusion The anti-IVA effect of 17β-estradiol may be associated with the IP3 receptor gene expression.

Objective To explore the application of three dimensionally structured nursing management mode in the treatment of multiple trauma patients. Methods One hundred and eighty-seven patients with multiple injuries in the emergency department of our hospital from January to December 2010 were set up as the control group, and the traditional method was used in the group. Another 189 patients with multiple injuries from January to December 2011 were set as the observation group , in which the three dimensionally structured nursing management mode was used. The two groups were compared in terms of success rate. Result The success rates of the observation group and the control group were 85.7%(162/189) and 71.7%(134/187), respectively. The difference between the two group was statistically significant (Χ2=19.19,P<0.01). Conclusion The implementation of the three-dimensionally structured nursing management model can improve the comprehensive ability of emergency treatment and then improve the success rate of rescuing emergency patients.

Objective To investigate the efficacy and toxicity of etoposide combined with prednisone (EtoP regimen) for elderly patients with unspecific peripheral T-cell lymphoma (PTCL-U) compared with the CHOP regimen.Methods 23 elderly PTCL-U patients were randomly assigned to EtoP group (n =12) or CHOP group (n =11).The curative effects and the adverse reactions were analyzed and compared between the two groups by Log-rank test and x2 test.Results The overall response (OR) rate was 66.67 ％ (8/12) in EtoP group and 63.64 ％ (7/11) in CHOP group.There was no statistically significant difference between the two groups(x2 =0.023,P =0.879).The progression-free survival (PFS) was 7.55 months in EtoP group and 4.38 months in CHOP group,statistically significant difference were observed between the two groups (x2 =23.000,P =0.011).The overall survival (OS) was 15.02 months in EtoP group and 12.26 months in CHOP group,no statistically significant difference was observed between the two groups (x 2 =14.985,P =0.597).The main side effects were bone marrow depression and digestive tract toxicity,no hematology toxicity and digestive tract toxicity of grade Ⅲ-Ⅳ occurred in EtoP group.Of those in CHOP group were 36.36 ％ and 27.27 ％.Conclusion For elderly PTCL-U patients,EtoP regimen is an effective and well tolerated therapeutic schedule.

Objective To evaluate 3D CT features of normal anatomy,anatomic variations and fractures of occipital squama.Methods The 3D CT features on MIP,VR images were analyzed retrospectively in 589 pediatric cases.The normal anatomy,anatomic variations and fractures of occipital squama were observed respectively,and the differential diagnostic features including the individual location,appearance and extension were analyzed.Results Four hundred and thirty-three patients (75.2％) showed normal anatomy,including 154 patients with adult occipital anatomical features,279 patients with posterior intraoccipital synchondrosis,and 37 patients with Kerckring-supraoccipital synchondrosis.When cases with recent trauma history were excluded,113 patients (19.1％) showed anatomic variants,including unpenetrating sutures and penetrating sutures.The former could be subdivided to Mendosal sutures in 23 cases,superior median fissures in 19 cases,and midline supraoccipital fissures in 4 cases,while the latter could be subdivided to the interparietal bone variations in 54 cases,wormian bones in 23 cases,and accessory bones in 7 cases.Two or more variations coexisted in 33 cases.The occipital squama fractures were shown in 34 cases (5.6％),including linear fractures in 27 cases,comminuted fractures in 3 cases,with depression fracture in one case,separation of cranial sutures in 3 cases,and other fractures associated with variants in 3 cases.The fractures were sharp,or jagged,without limitation of the occification.Conclusion There are different 3D CT features of normal anatomy,anatomic variations and fractures of occipital squama in children,which are important for making the accurate diagnosis.

Duck circovirus(DuCV),a potential immunosuppressive virus,was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction(PCR)based method. In this study,a total of 138 sick or dead duck samples from 18 different farms were examined with an average DuCV infection rate of～35%. It was found that ducks between the ages of 40～60 days were more susceptible to DuCV. There was no evidence showing that the DuCV virus was capable of vertical transmission. Farms with positive PCR results exhibited no regularly apparent clinical abnormalities such as feathering disorders,growth retardation or lower-than-average weight. The complete genomes of 9. strains from Fujian Province and 1 from Zhejiang Province were sequenced and analyzed. The 10 DuCV genomes,compared with others genomes downloaded from GenBank,ranged in size from 1988 to 1996 base pairs,with sequence identities ranging from 83.2% to 99.8%. Phylogenetic analysis based on genome sequences demonstrated that DuCVs can be divided into two distinct genetic genotypes,Group I(the Euro-USA lineage)and Group II(the Taiwan lineage),with approximately 10.0% genetic difference between the two types. Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species,including Duck,Muscovy duck,Mule duck,Cheery duck,Mulard duck and Pekin duck.

Objective To investigate high risk human papillomavirus(HR-HPV)prevalence among married women in Beijing and to study the high risk flactors.nethods During March 2007 to September 2008.a total of 6185 married women sampled from 137 communities in 12 districts were screened bv HR-HPV DNA test and cytogical test.The interview was carried out with unified questionnaires.The databage was set up and twice entered in EpiDam 3.0.After checked up,the data were analyzed in SPSS 15.0.Results (1) The HR-HPV infection rate was 9.89%.The HR-HPV infection rate of the city zone,the suburb and the exurb were 9.34%,10.51% and 9.51% (P>0.05).The HR-HPV infection rate of the native and the oudander were 9.53%,11.30% (P<0.05).(2) The age distribution of HR-HPV infection was that the rate was around 10% among 25 to 44 age groups,which was the highest(11.21%) in 30 to 34 age group;then the rate was descended as the age raising,the rate of 50 to 54 age group was the lowest(7.78%).(3) Multiple logistic regression showed that the related risk factors of HR-HPV infection mainly included 1000 RMB and above of family income per person per month.possessing more than 1 sexual partner of her husband,outlander and hish levels of education.(4) The prevalence of cervical intraepithelial neoplasia(CIN)in HR-HPV positive group wag significantly higher than that in HR-HPV negative group(29.76% vs 3.32%,P<0.01).Conclusions(1)The HR-HPV infection rate among aged 25 to 54 years was 9.9% and there was no significant difference in area distribution.(2)The hish risk population which should strengthen screening was the married bearing-age women with high level of family income,outlander,high levels of education and her husband possessing more than 1 sexual partner.(3)HR-HPV infection is the main risk factor for CIN and cervical cancer.while does not provide a causal relationship with them.The high risk population should be checked regularly to understand the development of HR-HPV infection and CIN incidence.
