Objective To analyze the clinical diagnosis and treatment of recurrent cancer in gastric remnant.Methods Clinical data of 48 patients who underwent surgical re-operation because of recurrent carcinoma within gastric remnant after radical resection of gastric cancer were analyzed retrospectively.Results All 48 cases were recurrent cancer in gastric stump.The time of recurrence was 6-36 months after first radical resection.After reoperation,the mean survival time of 28 patients(58.3%)who underwent radical resection was 40 months;the mean survival time of 20 patients(41.7%)who received palliative treatment was 14.8 months(P

Objective To study the causes of local recurrence,and diagnosis and treatment outcome of recurrent colorectal cancer.Methods The clinical data of 60 patients with recurrent colorectal cancer treated during 10 years in our hospital were analyzed retrospectively.Results Among the 60 cases,40 cases(66.7 %) had recurrence within 2 years after operation.Recurrence in anastomotic stoma,perineum,abdominal incision occurred and in the abdominal cavity and pelvic cavity in 15,10,7 and 20 cases respectively,and liver metastases were found in 8 cases.All patients underwent reoperation including curative surgery for 38 patients and palliative operation for 22 patients.After radical reoperation the 1-,3-,and 5-year survival rate was 93.6 %,48.8 %,and 36.3 %,respectively,and after palliative reoperation was 54.5 %,0 %,and 0 %,respectively.Conclusions Emphasizing the application of no-tumor touch technique,resection of adequate amount of bowel,performing complete lymphadenectomy and removal of micrometastatic lesions are the major measures to prevent recurrence of rectal cancer after operation.Integrative therapy regimens,of which surgical treatment is the major component,should be considered according to the location of recurrence and the clinical staging of the recurrent cases.

This study was aimed to observe the effects of herbal pair of Semen ziziphi spinosae (SZS) and A lbizia julibrissin flower (AJF) on the quality of life (QOL) among elderly patients with depression. A total of 70 elderly patients with depression were enrolled and randomly divided into two groups. The Chinese medicine group (with 35 cases) was given SZS-AJF decoction, and the western medicine group (with 35 cases) was given venlafaxine hydrochloride sustained-release tablets. The HAMD scale score, QOL Assessment Questionnaire (GQOLI-74), and the Side-Effects Scale Score (TESS) were detected 8 weeks before and after the treatment. The results showed that there was no significant difference on the clinical efficacy between two groups. On the comprehensive assessment of QOL, the physical function dimension, mental function dimension and QOL total score of Chinese medicine group were higher than the western medicine group with significant difference (P < 0.05). There were no significant differences on the material function dimension or social function dimensions between two groups. The HAMD score, physical function dimension, mental function dimension, social function dimension and score of QOL were all higher than the pretreatment score with significant differences in both groups (P < 0.05). The TESS score in Chinese medicine group was lower than the western medicine group. And the main adverse reactions in the Chinese medicines group were nausea and vomiting. It was concluded that the herbal pair of SZS and AJF had antidepressant efficacy. It can improve the QOL among elderly patients with depression.

A comparative observation about histological and histochemical study were made onthe preservating methods of local ischemic kidney of dogs.The methods of this exp-eriment were divided into five groups:A.Local hypothermia;B.Hypothermic perfu-sion solution 500ml,4℃,containing Procaine 450 mg and Heparin 100 mg,infusedinto renal artery;C.Hypothermic perfusion solution 500ml,4℃,containing 20% Ma-nniton 32ml,25% MgSO_4 0.36 ml,Heparin 100 ml,infused into renal artery;D.Localhypothermia and heparin 30 mg injected into the same vessel.E.Local room tem-perature.The specimens were taken from the kidneys of the experimental dogs atvarious period after treated with every method.The results were as follows;A,D and E group presented irreversible histological changes within 4 hoursaftertreatment.Four hours later,the reaction of SDH,ATPase,AlPase werenegative.It suggested that the kidney damage was serious,as well as expressed thatthe effect of these preservating methods for ischemic kidney are not satisfactory.In B group,the histological and histochemical alteration is very light and almostreversible,during 60 days after treatment.In C group,hypothermic perfusionsolution containing Mannitol,MgSO_4 etc either during experiment or follow observa-tion for 60 days,no histological and histochemical alterations were found.It indica-ted that this method is an ideal perservating technique for ischemic kidney.

Objective: To identify risk factors for positive surgical margin after laparoscopic radical prostatectomy. Method: The study retrospectively analyzed the records of 177 patients with prostate cancer who eventually underwent laparoscopic radical prostatecto-my from January 2016 to December 2017 in Peking University First Hospital. Age, prostate volume, prostate-specific antigen (PSA) be-fore needle biopsy, number of positive cores, positive percentage of needle biopsy and biopsy, and postoperative Gleason scoreand pathological stage were analyzed. Results: The overall positive surgical margin rate was 32.2% (57/177). Age, prostate volume, PSA be-fore needle biopsy, positive percentage of biopsy, and postoperative Gleason score were not significantly different (P>0.05). The study demonstrated significant differences between the number of positive cores, positive percentage of needle biopsy, and pathological stage (P<0.05). Multiple logistic regression revealed that the pathological stage was an independent factor affecting the positive surgi-cal margin rate (odds ratio, 1.616; 95% confidence interval, 1.062-2.459). Conclusions: The number of positive cores, positive percent-age of needle biopsy, and pathological stage significantly correlated with a positive surgical margin. The postoperative pathological T stage is an independent factor affecting positive surgical margins.

Objective:To analyze clinical factors related to nosocomial infection in children with extracorporeal membrane oxygenation(ECMO)support.Methods:General data, infection data and relevant factors in children with ECMO support in Bayi Children′s Hospital, the 7 th Medical Center of People′s Liberation Army General Hospital and Henan Provincial People′s Hospital from September 2012 to February 2020 were reviewed.Relevant factors of nosocomial infection in them were analyzed. Results:Among 163 cases, 36(22.1%) children supported with ECMO had infections during the period of ECMO, and 72 pathogenic microorganisms were detected, including 67 bacteria (33 Acinetobacter baumannii, 21 Klebsiella pneumoniae, and 6 Pseudomonas aeruginosa) and 5 fungi.Pathogens from the respiratory system, blood system, urinary tract and abdominal cavity were detected in 45 cases(62.5%), 25 cases (34.7%), 1 case (1.4%), and 1 case (1.4%), respectively.Drug sensitivity analysis of the Acinetobacter baumannii showed that it was the extensively resistant strain.Compared with uninfected children supported with ECMO, ECMO support time[(10.0±6.7) d], hospitalization[(34.0±25.3) d], hospitalization cost[(234 368±113 234) yuan], preoperative oxygenation index(52.8±23.0) and lactate value[(9.6±5.9) mmol/L]were significantly higher in nosocomial infection ones[(4.6±3.2) d, (24.3±19.8) d, (161 416±65 847) yuan, 35.6±10.4, (5.6±5.4) mmol/L] supported with ECMO (all P<0.05). There was no significant difference in the mortality between 2 groups ( P>0.05). In addition, lactate level (9.8 mmol/L) and oxygenation index (36.0±12.7) were significantly higher in died children(2.7 mmol/L, 22.1±10.4) with nosocomial infection during the period of ECMO support than those of survivors (all P<0.05). Multivariate Logistic regression analysis showed that ECMO support time( OR=7.054, 95% CI: 2.206-25.525) and preoperative lactate value( OR=2.250, 95% CI: 1.378-4.611) were independent risk factors of nosocomial infection. Conclusions:Correcting underlying diseases of ECMO supporting and shortening the duration of ECMO can reduce the incidence and mortality of nosocomial infection in children who are supported with ECMO.

Objective To investigate the effect of patient's body shape and image acquisition mode on the radiation dose and image quality in percutaneous coronary angiography.Methods A total of 40 patients,who received selective percutaneous coronary angiography at the Ningbo Medical Center Lihuili Hospital of China between January 2022 and June 2023,were selected for this study.The patients were randomly divided into conventional group(including 11 males and 9 females,using coronary angiography mode to make image acquisition)and low-dose group(including 14 males and 6 females,using electrophysiological mode to make image acquisition).The patient's basic information,body size data,and the various radiation dose data were collected.The image quality rating scale for assessing the image quality was formulated.The independent sample t-test and Mann-Whitney U test were used for the comparison between the two groups.Pearson correlation analysis method was used to make correlation analysis.Results The larger the patient's chest circumference was,the higher the radiation dose would be,there was a positive linear relationship between the patient's chest circumference and the radiation dose.All the radiation dose parameters in the low-dose group were significantly lower than those in the conventional group(P＜0.01),and its reduction percentage was 48.51％-60.74％.No statistically significant difference in image quality score existed between the two groups(P＞0.0l),and in both groups the image quality was rated as good or better,meeting the requirements of intervention procedures.Conclusion In percutaneous coronary angiography the radiation dose is influenced by multiple factors including patient's body shape,image acquisition mode,exposure time,etc.Optimizing the image acquisition mode can remarkably reduce the radiation dose while maintaining the image quality and protecting the health of patients and operators.(J Intervent Radiol,2024,33:599-603)

Objective: To investigate the infection status and genotype distribution of cervical human papillomavirus (HPV) in women of different ethnic groups and different ages in Yili, Xinjiang Uygur Autonomous Region (Xinjiang). Methods: By using the convenient sampling method, 54 760 women from November 2015 to May 2017 seeking for service in gynecological clinics in a general hospital in Yili, Xinjiang, were selected as the research subjects, and 3 445 samples of cervical mucous exfoliative cells were collected, and the social information of their ethnic and age was collected at the same time. The inclusion criteria were those with sexual life, cervical integrity, and ethnic groups for Han or Uygur or Kazak. PCR-reverse dot blot hybridization was used to detect HPV genotyping in exfoliated cells, and chi-square test was used to compare the difference of HPV positive rate among different ethnic groups. Then, according to ethnicity and age, the differences in positive rates of different ages and ethnic groups were compared in each layer. Results: The positive rate of HPV was 25.6% (882 cases), of which the Han, Uygur and Kazakh were 27.9% (564 cases), 22.9% (196 cases) and 21.6% (122 cases), and the difference was statistically significant (χ²=13.80, P=0.001). The most prevalent high-risk genotypes of Han women were HPV16/52/58, accounting for 24.8% (140 cases), 17.7% (100 cases) and 9.8% (55 cases), respectively. The most prevalent high-risk genotypes of Uygur women were HPV16/52/53, accounting for 34.2% (67 cases), 12.8% (25 cases), 9.2% (18 cases), respectively. The most prevalent high-risk genotypes of Kazak were HPV16/52/53, accounting for 37.7% (46 cases), 17.2% (21 cases), 12.3% (15 cases), respectively. The highest rate of HPV in Uygur patients aged ≥61 years was 41.5% (22 cases), and the lowest in group 36-40 years old, 15.9% (21 cases), the difference between different age groups was statistically significant (χ²=35.01, P<0.001). Conclusion The positive rate of HPV infection among Han, Uygur and Kazak in Yili Prefecture of Xinjiang was different, and the HPV positive genotype differs among different ethnic groups.

Objective To characterize the clinicopathologic features,treatment efficacy and prognoses of proliferative glomerulonephritis with monoclonal IgG deposits (PGNMID) in renal allografts.Methods Electronic medical records of Jinling Hospital were searched for PGNMID that was diagnosed during January 2008 to April 2017.Clinicopathologic features,treatment regimens and prognoses information were retrieved and analyzed.Results We identified 5 cases of PGNMID with clinical symptoms of proteinuria (5/5),serum creatinine elevation (4/5) or hematuria (4/5) 5 to 19 months after kidney transplantation.Various light microscopic features were observed,with predominantly membranoprolifeative pattern.Mild mesangial proliferation pattern could be observed in early stages of disease progression.Immunofluorescence revealed monoclonal IgG3κ in 3 patients and IgG3λ in another 2 cases.One case of PGNMID with normal light microscopy but monoclonal IgG deposits was verified by IgG and light-chain subtyping.In the 4 patients treated with rituximab or bortezomib,decreased proteinuria was achieved in all treated patients while the decreases in serum creatinine decrease were only observed in 2 patients At last follow-up,one patient was in dialysis and serum creatinine levels of other 2 patients were ＞265.2 μmol/L.Conclusion Membranoprolifeative pattern is the most frequently observed microscopic findings and IgG3 is the most frequent IgG subtype in PGNMID.PGNMID recurs shortly after kidney transplantation.Rituximab and/or bortezomib is conducive to decrease proteinuria while their efficacy to decrease serum creatinine is dubious.The most effective treatment protocol for PGNMID remains to be determined in larger samples.

Objective:To explore the clinicopathologic features and renal prognosis of patients with post-transplant membranous nephropathy (MN).Methods:Patients with allograft biopsy-proven MN were reviewed retrospectively and divided into unknown etiology group (A, n=12) and recurrent membranous nephropathy (rMN) group (B, n=7). Their clinicopathological data and renal prognosis were assessed and compared.Results:No differences existed in the proportion of living-related donor or post-transplant allograft function. Group B had recurrence at 16.4 months after transplantation and it was significantly shorter than group A. Allograft impairment manifested as proteinuria, nephrotic syndrome and/or renal insufficiency in both groups. The positive rate of serum anti-PLA2R antibody and renal PLA2R staining was significantly higher in group B than that in group A. Similarly, the intensity of IgG4 subtype staining was also stronger in group B than that in group A. The 5-year cumulative renal survival rates from end-stage renal disease (ESRD) were 77.8% and 66.7% in groups A and B respectively. No significant inter-group difference existed in renal prognosis.Conclusions:Anti-PLA2R antibody plays an important role in the recurrence of rMN after renal allografting. PLA2R staining is useful for detecting primary disease and its sensitivity is higher than that of serum anti-PLA2R antibody. Rituximab is an effective treatment for post-transplant MN. Follow-up studies with a larger sample size are required for further verification.
