Objective To evaluate the treatment of hypervascular hepatic metastasis with TACE. Methods One hundred and twenty nine cases of hepatic metastasis treated by TACE were selected retrospectively and then analyzed the survival rate,clinical effectiveness and lipidol deposition quantity in tumor.Results Malformation of tumor vessels and rich blood supply were found in all cases of this study.The survival rates of 6 months,1 year and 3 years were 100%,73.6% and 26.4% respectively.The clinical effective rate was 68.2%(88/129)and no-progress rate was 23.3%(30/129).The satisfactory lipidol deposition quantity was obtained in 80.9%(97/129).Conclusions TACE is a favorable method for hepatic metastasis,and discerning the hypervascular subgroup could improve the treating effectiveness and be useful to make an appropriate planning.

OBJECTIVETo study the therapeutic effect of combined therapy with Chinese drugs and immuno-suppressors, mainly anti-lymphocyte globulin/anti-thymus globulin (ALG/ATG), for the treatment of severe aplastic anemia (SAA), the efficacy associated factors and adverse effects as well.

METHODSA retrospective analysis was conducted on 65 patients with SAA treated by combined therapy which was supplemented with cyclosporin A, androgen, hematopoietic growth factor, etc.

RESULTSOf the 57 patients followed-up, 26 (45.6%) were basically cured, 15 (26.3%) remitted, and 8 (14.0%) improved markedly, the total effective rate being 85.9%. By separately comparing with a single item of clinical data, it was shown that the therapeutic effectiveness was correlated, to a certain extent, with age, illness duration, neutrophil count, and bone marrow proliferation in patients before treatment, as well as with infection that occurred in the follow-up period. It was obviously higher in patients with peripheral neutrophil count > 0.5 x 10 10(9)/L (P<0.05). Various degrees of serum sickness-like reactions occurred in the treatment of 36 patients, including fever in 36 (63.2%), skin rash in 8 (14.0%), and musculoskeletal pain in 5 (8.8%).

CONCLUSIONSThe therapeutic effect of combined therapy with Chinese drugs and ALG/ATG in treating SAA could be affirmed, showing some superiority as compared with Western medicine alone. The patients' age, duration of illness, neutrophil count, and bone marrow proliferation before treatment, and degree of infection that occurred could affect the therapeutic efficacy to a certain extent. Adverse reactions resulting from the combined therapy are less, showing the toxicity reducing and effect enhancing action of Chinese drugs.

OBJECTIVETo evaluate the efficacy and safety of neoadjuvant chemotherapy in patients with locally advanced gastric cancer, and to analyze the relevant factors of recurrent death of gastric cancer after adjuvant chemotherapy.

METHODSClinical data of 49 patients who underwent neoadjuvant chemotherapy for locally advanced gastric cancer between July 2007 and June 2011 were reviewed. Preoperative staging was determined by endoscopic ultrasonography and abdominal computer tomography (CT) or magnetic resonance imaging (MRI). Chemotherapy was administered for regimen of two or three drugs. Prognostic factors were analyzed by univariate and multivariate analysis with Cox proportional hazard model.

RESULTSThe response rate was 33.3% (16/48) and disease control rate was 93.8% (45/48). Forty-four (89.8%, 44/49) patients received curative resection after neoadjuvant chemotherapy, among whom 90.9% (40/44) underwent D2 lymphadenctomy. Thirty-two cases had pathological response and 2 patients had pathological complete response. The average hospital stay was 11.6 days and 2 patients had longer hospitalization because of postoperative pancreatic complications. The toxicities were most in grade 1-2. All the patients were followed up postoperatively and the median follow-up was 21.6 months. Median progression-free survival was 29.6 (95%CI:24.0-35.2) months and median overall survival was 34.6 months (95%CI:29.8-39.4). Imaging response (P=0.038, RR=0.168, 95%CI:0.031-0.904) and pathological response (P=0.007, RR=0.203, 95%CI:0.064-0.642) were identified as independent prognostic factors with COX multivariate analysis.

CONCLUSIONSNeoadjuvant chemotherapy has quite high disease control rate and R0 resecting rate for patients with locally advanced gastric cancer. Imaging response and pathological response are most important prognostic factors in those patients.

Objective· To summarize the clinical characteristics and prognostic factors of pelvic chondrosarcoma. Methods · A total of 73 cases of chondrosarcoma were collected, including 24 of pelvic. The clinical characteristics and prognostic factors of pelvic chondrosarcoma were analyzed by statistic methods. Results · The ratio of men to women was 1.4:1,and the median age is 43.5 years old. According to the classification of pelvic proposed by Enneking, there were 5 in region Ⅰ?, 14 in region Ⅱ?, and 5 in region Ⅲ?. On histological review, 1 was grade 1, 15 were grade 2 ,and 8 were grade 3. The histologic types included 17 conventional, 3 dedifferentiated, 2 secondary, and 1 mesenchymal. The overall survival rates of pelvic chondrosarcoma were (82.2±8.1) %,(77.3±8.9) % and(52.4±12.1) % for 3, 5 and 10 years respectively. Local recurrence rate of pelvic chondrosarcoma (83.3%) was significantly higher than those of other sites(34.7%)(P=0.000),and the proportion of amputation was significantly higher than the other sites(50.0% vs 20.4%, P=0.000), but there was no significant difference in the overall survival between the two groups (P=0.216). Conclusion · Pelvic chondrosarcoma have a higher local recurrence rate than the other sites and is tend to result in amputation. Early local recurrence after surgery indicates poor prognosis.

Complex coronary heart disease (CHD) has become a hot spot in medicine due to its complex coronary anatomy, variable clinical factors, difficult hemodynamic reconstruction, and limited effect of conservative drug treatment. Identifying complex CHD and selecting optimal treatment methods have become more scientific as revascularization technology has improved, and coronary risk stratification scores have been introduced. SYNTAX and its derivative scores are decision-making tools that quantitatively describe the characteristics of coronary lesions in patients based on their complexity and severity. The SYNTAX and its derivative scores could assist clinicians in rationalizing the selection of hemodynamic reconstruction treatment strategies, and have demon-strated outstanding value in evaluating the prognosis of patients with complex CHD undergoing revascularization treatment. The authors in this article summary the practical application of SYNTAX and its derivative scores in complex CHD in order to deepen the understanding of the relationship between the choice of different revascularization strategies and SYNTAX and its derived scores in complex CHD and provide a further reference for clinical treatment of complex CHD.

BACKGROUND: Positive surgical margins are independent risk factor for biochemical recurrence, local recurrence, and distant metastasis after radical prostatectomy. However, limited predictive tools are available. This study aimed to develop and validate a preoperative nomogram for predicting positive surgical margins after laparoscopic radical prostatectomy (LRP). METHODS: From January 2010 to March 2016, a total of 418 patients who underwent LRP without receiving neoadjuvant therapy at Peking University Third Hospital were retrospectively involved in this study. Clinical and pathological results of each patient were collected for further analysis. Univariable and multivariable logistic regression (backward stepwise method) were used for the nomogram development. The concordance index (CI), calibration curve analysis and decision curve analysis were used to evaluate the performance of our model. RESULTS: Of 418 patients involved in this study, 142 patients (34.0%) had a positive surgical margin on final pathology. Based on the backward selection, four variables were included in the final multivariable regression model, including the percentage of positive cores in preoperative biopsy, clinical stage, free prostate specific antigen (fPSA)/total PSA (tPSA), and age. A nomogram was developed using these four variables. The concordance index (C-index) of the nomogram was 0.722 in the development cohort and 0.700 in the bootstrap validations. The bias-corrected calibration plot showed a limited departure from the ideal line with a mean absolute error of 2.0%. In decision curve analyses, the nomogram showed net benefits in the range from 0.2 to 0.7. CONCLUSION A nomogram to predict positive surgical margins after LRP was developed and validated, which could help urologists plan surgical procedures.

OBJECTIVE: To investigate the safety and feasibility of laparoscopic treatment for renal carcinoma with Mayo 0-2 level venous thrombosis. METHODS: From January 2015 to February 2018, 58 renal carcinoma cases with venous thrombus underwent laparoscopic radical nephrectomy with inferior vena cava thrombectomy in Department of Urology, Peking University Third Hospital, of which, 51 cases were male, and 7 female, aged 29-82 years. According to the Mayo grade classification, 20 cases were level 0, 20 cases were level 1, and 18 cases were level 2, with left side being 22 cases, and right side 36 cases. The patients except for those complicated with hemorrhagic diseases, cardiac and pulmonary insufficiency, or those who could not tolerate anesthesia and surgical contraindications, underwent the operation after comprehensive examinations. RESULTS: The 58 cases of renal tumor with venous tumor emboli were successfully completed with the surgeries, including 50 cases of totally laparoscopic surgery, 8 cases of laparoscopy surgery from convert to open (among the patients who were converted to open surgery, 7 were complicated with grade 2 tumor thrombus and 1 with grade 1 tumor thrombus). The main reasons for converting to open surgery were huge tumors (the largest of which was about 16 cm in diameter), severe adhesion and difficulty of separation. For different patients, different surgical methods and procedures were adopted according to the tumor direction and the different grade of tumor thrombus. Radical nephrectomy combined with vena cava tumor thrombus removal was performed in 55 cases and segmental resection of vena cava in 3 cases. The operation time was 132-557 min, and blood loss was 20-3 000 mL. Post-operative pathological types: 51 cases were clear cell carcinoma, 5 cases were type 2 of papillary carcinoma, 1 case was squamous cell carcinoma, and 1 case was chromophobe cell tumor. In the study, 47 cases were followed up for 1-36 months, and 4 cases died (the survival time was 5-15 months, with an average of 10.2 months). CONCLUSION Laparoscopic radical nephrectomy with inferior vena cava thrombectomy is a reasonable choice for renal tumor with Mayo 0-2 level venous thrombosis. For different tumor directions and different grades of tumor thrombus, an appropriate operation plan can give the maxim benefit to the patients with skillful surgeons.

Objective: To evaluate the safety, efficacy and tolerability of China-made sildenafil citrate (Jinge) in the treatment of ED. METHODS: We conducted a multi-center, randomized, double-blind and placebo-controlled clinical trial among 222 ED patients in five urological or andrological clinics of China. The patients were randomly assigned to receive sildenafil citrate (SC, n = 111) or placebo (n = 111) for 8 weeks. We obtained and analyzed the demographic and clinical characteristics of the patients, the scores of International Index of Erectile Function (IIEF), the success rate of sexual intercourse, and the incidence of adverse events. RESULTS: No statistically significant differences were found between the patients of the SC and those of the placebo group in the mean age (［47.2±11.32］ yr vs ［46.67±13.08］ yr, P>0.05), psychological etiology (27.93% vs 23.42%, P>0.05), organic etiology (21.62% vs 29.73%, P>0.05) or mixed etiology (50.45% vs 46.85%, P>0.05), nor in height, weight, nationality, or history of smoking, drinking or allergy. Compared with the placebo controls, the SC-treated patients showed significant increases in the excellence rate of effectiveness (29.91% vs 78.90%, P<0.01), success rate of sexual intercourse (29.16% vs 63.87%, P<0.01), and total effectiveness rate (34.58% vs 77.98%, P<0.01). The effectiveness rates on organic, psychogenic and mixed types ED were remarkably higher in the SC group (64.52%, 83.33%, and 82.14%) than in the placebo control (46.15%, 21.21%, and 25.00%) (P<0.01). Mild or temporary adverse events were observed in 32 cases in the SC group as compared with 13 in the placebo control. CONCLUSIONS China-made sildenafil citrate is an effective, safe and well-tolerated drug for ED of different etiologies in the Chinese population.

【Objective】 To objectively evaluate the quality control level of blood testing process in blood banks through quantitative monitoring and trend analysis, and to promote the homogenization level and standardized management of blood testing laboratories in blood banks. 【Methods】 A quality monitoring indicator system covering the whole process of blood collection and supply, including blood donation service, blood component preparation, blood testing, blood supply and quality control was established. The questionnaire Quality Monitoring Indicators for Blood Collection and Supply Process with clear definition of indicators and calculation formulas was distributed to 17 blood banks in Shandong province. Quality monitoring indicators of each blood bank from January to December 2022 were collected, and 31 indicators in terms of blood testing were analyzed using SPSS25.0 software. 【Results】 The proportion of unqualified serological tests in 17 blood bank laboratories was 55.84% for ALT, 13.63% for HBsAg, 5.08% for anti HCV, 5.62% for anti HIV, 18.18% for anti TP, and 1.65% for other factors (mainly sample quality). The detection unqualified rate and median were (1.23±0.57)% and 1.11%, respectively. The ALT unqualified rate and median were (0.74±0.53)% and 0.60%, respectively. The detection unqualified rate was positively correlated with ALT unqualified rate (r=0.974, P<0.05). The unqualified rate of HBsAg, anti HCV, anti HIV and anti TP was (0.15±0.09)%, (0.05±0.04)%, (0.06±0.03)% and (0.20±0.05)% respectively. The average unqualified rate, average hemolysis rate, average insufficient volume rate and the abnormal hematocrit rate of samples in 17 blood bank laboratories was 0.21‰, 0.08‰, 0.01‰ and 0.02‰ respectively. There were differences in the retest concordance rates of four HBsAg, anti HCV and anti HIV reagents, and three anti TP reagents among 17 blood bank laboratories (P<0.05). The usage rate of ELISA reagents was (114.56±3.30)%, the outage rate of ELISA was (10.23±7.05) ‰, and the out of range rate of ELISA was (0.90±1.17) ‰. There was no correlation between the out of range rate, outrage rate and usage rate (all P>0.05), while the outrage rate was positively correlated with the usage rate (r=0.592, P<0.05). A total of 443 HBV DNA positive samples were detected in all blood banks, with an unqualified rate of 3.78/10 000; 15 HCV RNA positive samples were detected, with an unqualified rate of 0.13/10 000; 5 HIV RNA positive samples were detected, with an unqualified rate of 0.04/10 000. The unqualified rate of NAT was (0.72±0.04)‰, the single NAT reaction rate [(0.39±0.02)‰] was positively correlated with the single HBV DNA reaction rate [ (0.36±0.02) ‰] (r=0.886, P<0.05). There was a difference in the discriminated reactive rate by individual NAT among three blood bank laboratories (C, F, H) (P<0.05). The median resolution rate of 17 blood station laboratories by minipool test was 36.36%, the median rate of invalid batch of NAT was 0.67%, and the median rate of invalid result of NAT was 0.07‰. The consistency rate of ELISA dual reagent detection results was (99.63±0.24)%, and the median length of equipment failure was 14 days. The error rate of blood type testing in blood collection department was 0.14‰. 【Conclusion】 The quality monitoring indicator system for blood testing process in Shandong can monitor potential risks before, during and after the experiment, and has good applicability, feasibility, and effectiveness, and can facilitate the continuous improvement of laboratory quality control level. The application of blood testing quality monitoring indicators will promote the homogenization and standardization of blood quality management in Shandong, and lay the foundation for future comprehensive evaluations of blood banks.
