Objective To evaluate the feasibility,safety and effectiveness of modified associating liver partition and portal vein ligation for staged hepatectomy (ALPPS).Methods The published literatures associated with modified ALPPS were pooled from Embase,Pubmed,Medline,Google Scholar databases.The studies were included or excluded depends on our predetermined criteria.We selected data and performd descriptive analysis from the included studies.Results Five articles were included and reviewed.A total of 62 patients underwent five modified procedures,including monosegment ALPPS (m-ALPPS),anterior approach ALPPS,partial-ALPPS,radiofrequency-assisted liver partition with portal vein ligation (RALPP) and associating liver tourniquet and portal ligation for staged hepatectomy (ALTPS).There were 50 (80.6％) patients diagnosed liver metastatic colorectal cancer.The average operation interval of modified ALPPS was between 8 ～ 22 days and growth rate of future liver remnant (FLR) ranged from 48.7％ to 62.3％,the feasibility to perform ALPPS stage 2 was 98.4％.The incidence of severe postoperative complications were between 11.8％ ～33.3％.The 90-day mortality for monosegment ALPPS,partial-ALPPS and RALPP was 0,while the figure was 8.3％ in ALTPS.The in-hospital morbidities were 5.9％ and 8.3％ for anterior approach ALPPS and ALTPS,respectively,which were 0 in the other three modified groups.Clinical response evaluation,including R0 resection rate,overall survival rate,disease-free and recurrence rates were merely presented 83.3％,80％,50％,50％ in m-ALPPS group,while 100％,100％,95％,5％ in modified ALTPS group.Conclusion Modified ALPPS with improved safety is feasible in clinical practice.However,the effectiveness still needs further studies.

Objective To promote the migratory ability and immunological effect of bone marrow-derived dendritic cells ( BMDC) loaded with breast carcinoma antigen. Methods DCs were cultured by the medium containing rmGM-CSF and rmIL-4. After loaded with breast carcinoma antigen, DCs were stimulated with PGE2 for 1day. CD86, CD80, and CCR7 were measured by flow cytometry. The expression of CCR7 on surface of BMDC was also detected by RT-PCR and Western blotting. The chemotaxis assay was measured by migration through a polycarbonate filter in transwell chambers. The competence of inducing mixed lymphocyte response (MLR) and specific cytotoxic T lymphocyte ( CTL) were detected with MTT. The effect of DC blocking tumor growth in breast carcinoma model were also studied. Results Compared with control group, PGE2 upregulated surface markers of CD86, CD80, and CCR7 (P

Background and purpose:Long non-coding RNA (lncRNA) could be an important player in cancer biology. Recent studies showed that lncRNA PCGEM1 might be important in the regulation of androgen recep-tor (AR) signaling pathway. We tried to observe the expressions of lncRNA PCGEM1 and AR in prostate cancer, and investigate their role and signiifcance in prostate cancer genesis and progress.Methods:The expression of lncRNA PCGEM1 was observed in prostate cancer by lfuorescencein situ hybridization (FISH) technique. Then detection of AR was performed by immunolfuorescence histochemistry methods. Their co-effective role was checked by RNA pull-down technique.Results:Compared with the AR-independent cell line such as PC3 or DU145, AR-dependent cell line such as LNCaP showed much higher expression of lncRNA PCGEM1 (P<0.01). PCGEM1 and AR could be co-localized in most of these prostate cancer samples, especially in the metastasis samples. Moreover, androgen deprivation promoted the translocation of PCGEM1 into nucleus. RNA pull-down results also proved the co-effective role of PCGEM1 and AR.Conclusion:This study showed that lncRNA PCGEM1 was highly expressed in metastatic prostate cancer. It was related to the progress and malignant behavior of the prostate cancer. Its co-localization with AR may play an important role in prostate cancer genesis and progress.

Objective:To systematically evaluate the therapeutic efficacy of enteral nutrition(EN)versus parenteral nutrition(PN)in patients after liver transplantation(LT).Methods:The databases of Cochrane Library, MEDLINE, EmBase, EBSCO, Sinomed, CBM, CNKI and Wanfang Data were systematically searched up to August 2021 for collecting randomized controlled trials(RCT)of comparing EN and PN in patients after LT.In strict accordance with the inclusion and exclusion criteria, two independent researchers carried out literature screening, data extracting and literature methodological quality evaluations.Then RevMan5.3 software was utilized for quantitative synthesis and statistical processing.Results:A total of 13 RCTs involving 571 grade B patients were included.Meta-analysis indicated that, as compared with PN, serum albumin of EN spiked[WMD=2.5(1.33, 3.68), WMD>0, P<0.000 1], prealbumin rose[WMD=59.78(32.22, 87.35), WMD>0, P<0.000 1], total bilirubin dropped[WMD=-27.81(-41.88, -13.74), WMD<0, P=0.000 1]and infection incidence was significantly lower[ OR=0.25(0.16, 0.39), OR<1, P<0.000 01]. Conclusions:After LT, as compared with PN, EN can boost the nutritional level, promote the recovery of liver function and lower the incidence of postoperative infections.It offers some clinical values.

Objective To study clinical characteristics of type 2 diabetic(T2D)patients with metabolic syndrome(MS)and its components in Beijing urban communities.Methods Totally,3295 T2D patients involved in a combined prospective diabetic management study from 15 urban communities in Beijing were classified as four groups, according to 2004 Chinese Diabetes Society's definition of MS, i. e, isolated T2D, T2D with one component of MS, T2D with two components of MS and T2D with three components of MS. Their clinical characteristics were analyzed. Results ( 1 ) Among 3295 T2D patients, 155 (4. 7% )were isolated T2D, 107 (32.6%) T2D with one component of MS, 1386 (42.1%) T2D with two components of MS and 679 (20.6%) T2D with three components of MS, with an overall 62.7% (2065/3295) of T2D patients complicated with MS. (2) In these T2D patients, the more components of MS they had, the higher body mass index (BMI), waist circumference, waist to hip circumference ratio (WHR),systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting serum levels of insulin and triglyceride (TG) and the lower level of high-density lipoprotein-cholesterol (HDL) were presented (P <0. 01 ). (3) Percentage of isolated T2D in women increased from 49. 0% (76/155) to 61.9% (420/679)of those with three components of MS ( P < 0 01 ), with increasing of components of MS. (4) Multiple logistic regression analysis showed that BMI, history of hypertension, decreased HDL, increased TG,increased blood pressure, all were risk factors for T2D patients complicated with MS. Conclusions Among T2D patients in urban communities of Beijing, 95.3% (3140/3295) of them complicated with one or more components of MS, and 61.9% (420/679) of them complicated with MS. So, community diabetic management must be implemented in an all-round way, including control of blood pressure, blood lipids,body weight and so on, in addition to control of blood sugar.

Objective To investigate current status of use of oral hypoglycemic drugs and insulin among adult patients with type 2 diabetes mellitus (T2DM) in urban community of Beijing.Methods In total,3297 T2DM patients aged more than 20 years from 15 urban communities of Beijing were studied.Their body weight,height,fasting plasma glucose level and glycosylated hemoglobin Alc (HbAlc) were measured.A door-to-door questionnaire survey on use of oral hypoglycemic drugs and insulin was conducted for them.All the T2DM patients surveyed were divided into four groups based on their received intervention.Results ①Of 3279 T2DM patients,454 (13.8％) received lifestyle intervention,971 (29.5％) used only one oral hypoglycemic drug,1179 (35.7％) with combined oral hypoglycemic drugs,and 693(21.0％) with insulin.②There was significant difference in average HbAlc among the four groups of T2DM patients with lifestyle intervention,only one oral hypoglycemic drug,combined oral hypoglycemic drugs,and insulin,with HbAI c of (7.0 ± 1.9) ％,(7.1 ± 1.5) ％,(7.4 ± 1.5 ) ％,and (7.5 ± 1.5 ) ％for them,respectively ( F =15.1,P ＜ 0.01 ).Proportions of the T2DM patients with HbAlc equal to or higher than 7.0％ were 32.2％,39.4％,52.1％ and 59.5％ for the four groups,respectively ( x2 =117.7,P ＜ 0.01 ).③In the T2DM patients with lifestyle intervention,32.2％ (146/454) of them with HbA1 c equal to or higher than 7.0％ were untreated with any oral hypoglycemic drug.In those with only one oral hypoglycemic drug,39.4％ (383/971) of them with HbAlc equal to or higher than 7.0％ were not treated with combined oral hypoglycemic drugs and/or insulin.In those with combined oral hypoglycemic drugs,52.1％ (614/1079) of them with HbAlc equal to or higher than 7.0％ were not received combined insulin treatment.④ Fasting plasma glucose level,treatment strategies,postprandial 2-h blood glucose level and length of the illness were independent risk factors for HbAlc level equal to or higher than 7.0％,with odds ratio (OR) of 1.757,1.256,1.175 and 1.031,respectively.⑤ In 2843 T2DM patients with oral hypoglycemie drugs and/or insulin treatment,1494 (52.6％ ) received biguanides and 693 received (24.4％ )insulin,respectively.Conclusions More than half of adult patients with T2DM do not meet the target of glycemic control of HbAlc less than 7.0％ in urban communities of Beijing,due to not active use of oral hypoglycemic drugs,and not timely adoption of combined use of oral hypoglycemic drugs and insulin therapy.

Objective To investigate the prevalence of dyslipidemia in subjects with type 2 diabetes mellitus in Beijing urban communities.Methods Total 3316 subjects with type 2 diabetes (age 20-80 years) were recruited from 15 urban community health centers in Beijing using a multi-stage random sampling approach.Dyslipidemia was diagnosed according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults:2007 version.Results Among 3316 diabetic subjects (1329 malesand 1987 females),75.6％ (2506/3316) had dyslipidemia,the prevalence was 72.5％ (964/1329)in men and 77.6％ (1542/1987) in women.The prevalence of hypertriglyceridemia and hypercholesterolemia was 41.9％ (1388/3316) and 48.1％ (1595/3316),respectively.31.5％ (1043/3316) subjects had high levels of low-density lipoprotein cholesterol (LDL-C) and 21.2％ (703/3316) had low high-density lipoprotein cholesterol (HDL-C).Among all subjects with dyslipidemia only 22.9％ (575/2506) took hypolipid agents.The overall blood lipid control rates of triglyceride (TG),total cholesterol (TC),LDL-C and HDL-C in 1393 subjects with dyslipidemia history were 48.0％ (669/1393),17.4％ (242/1393),30.9％ (430/1393) and 75.8％ (1056/1393),respectively.Diabetics with dyslipidemia had higher body mass index,waist circumference,blood pressure,plasma glucose and hemoglobin A1c.The prevalence of dyslipidemia in the overweight and uncontrolled-glucose group were 79.0％ (1678/2125),78.9％ (1756/2227),respectively.Logistic regression analysis showed that gender,age,body mass index and hemoglobin A1c were associated with dyslipidemia.Conclusions The prevalence of dyslipidemia in diabetic subjects in Beijing urban communities is high and less than one quarter patients take hypolipid agents.Age,body mass index and hemoglobin A1c are the risk factors of dyslipidemia in type 2 diabetic patients.
