OBJECTIVETo analyze the risk factors of postoperative complications in gastric carcinoma patients complicated with liver cirrhosis.

METHODSA retrospective research of 41 gastric cancer patients with liver cirrhosis who underwent surgical therapy was performed. The multivariate Logistic regression analysis was carried out to determine risk factors of postoperative complications.

RESULTSThere were no postoperative death in this cohort. Twenty-seven(65.9%) patients developed postoperative complications. As determined by the Logistic regression analysis, Child-Pugh score(OR=27.96, 95% CI:1.16-672.23), albumin level(OR=17.98, 95% CI:1.28-253.36) and intraoperative blood loss(OR=10.60, 95% CI:1.21-92.82) were independent risk factors of postoperative complications.

CONCLUSIONAs for gastric cancer patients with liver cirrhosis, positive perioperative management, adjustment of Child-Pugh classifications score, following damage control principle during operation and reducing the intraoperative bleeding may decrease the morbidity of postoperative complications.

OBJECTIVETo evaluate the efficacy and optimal re-implantation time of two-stage revision for management of periprosthetic infection following hip arthroplasty.

METHODSWe retrospectively analyzed the clinical data of 15 patients (15 hip joints) undergoing two-stage ipsilateral total hip arthroplasty (THA) revision from January, 2006 to January, 2010. In the first stage, after surgical debridement and thorough removal of all the implants, a self-made Vancomycin-loaded cement spacer was implanted. The second stage operation was performed 3-6 months later for debridement and removal of the antibiotic-loaded spacer, followed by re-implantation of Vancomycin-loaded bone cement prosthesis in 9 cases and cementless prosthesis in 6 cases. The patients were followed up for 9-46 months (mean 25 months) after the operation.

RESULTSNo reinfection or prosthesis loosening/displacement was found in these cases after the operation. The Harris score increased from 40.3 before the operation to 54.0 after the first-stage operation, and to 88.2 at the last follow-up.

CONCLUSIONTwo-stage revision is effective for treatment of periprosthetic infection following hip arthroplasty, and 3-6 months can be the optimal interval between the two the first-stage and second-stage operation for re-implantation.

OBJECTIVETo establish a novel model of lumbar disc degeneration on the early stage in the rhesus monkey using percutaneous needle puncture guided by CT.

METHODS(1) Thirteen rhesus monkeys aged from 4 to 7 years, female 7 and male 6 were selected for establishing a model of the early stage of lumbar disc degeneration. (2)13 monkeys, 91 discs were divided into 3 groups: 64 discs from L1/2 to L5/6 were percutaneous punctured with a needle 20G as experimental group and 1 disc with a needle 15G as puncture control group and 26 discs were not be punctured from L6,7 to L7-S1 as control group. (3) Lumbar disc localization for needle puncture was guided by CT. All discs were examined by MRI, the HE, Masson's trichrome, Safranine-O and immunohistochemical staining of type II collagen before disc puncture and after puncture at 4, 8 and 12 weeks.

RESULTSMRI: (1) Experimental group: Pfirmann's Grade I was shown at postoperation 4, 8 and 12 weeks; (2) Puncture control group: Grade III was shown at postoperation 4 weeks and Grade IV at 8 weeks; (3) CONTROL GROUP: Grade I was shown at postoperation 4, 8 and 12 weeks. Histological examination: (1) In experimental group, there was no any change at postoperation 4 weeks, and the cell population of the nucleus was decreased at 8 weeks and more decreased at 12 weeks in HE. (2) There was no any change at postoperation 4 weeks, the clefts among the lamellae of the annulus fibrosus (AF) were shown at 8 weeks and more wider of the clefts of AF at 12 weeks in Masson's trichrome. (3) No any change was shown at postoperation 4 weeks, proteoglycan were progressively decreased at 8 and 12 weeks in Safranine-O. (4) No statistically significant difference in positive rate was observed at 4 and 8 weeks compared with control group in immunohistochemical staining of type II collagen. There was statistical difference at 12 weeks compared with control group (P<0.05). In puncture control group postoperation 8 weeks, the morphology of cell of nucleus pulposus was not clear in HE. The wider clefts of lamellae of the AF were shown in Masson's trichrome. The proteoglycan was obviously decreased in Safranine-O. Immunohistochemical staining collagen II synthesized was decreased. In normal control group, no any change was shown at 4, 8 and 12 weeks.

CONCLUSIONSThe degeneration of lumbar intervertebral disc on the early stage could be induced by the percutaneous needle puncture (20G) to the annulus fibrosus. The assessment of disc degeneration on early stage is not shown on MRI and only confirmed by histological examination.

OBJECTIVETo evaluate the clinical efficacy of Jianpi Liqi Yiliu Formula (JLYF) combined with cytokine-induced killer (CIK) cells for treating patients with advanced hepatocellular carcinoma (HCC).

METHODSBetween January 2011 and January 2014, 60 advanced HCC patients were enrolled in this study, who were assigned to the treatment group and the control group according to their willingness for taking JLYF, 30 cases in each group. All patients received CIK cell treatment: 1 x 10⁹-3 x 10⁹ each time, by intravenous dripping from the 1st day to the 3rd day, once per day. Besides, patients in the treatment group took JLYF decoction, while those in the control group took Chinese medical decoction by syndrome typing. All patients received treatment of at least two cycles. The time to progression (TTP) , overall survival (OS), disease control rate (DCR), performance status scale (PS), Child-Pugh scale, and adverse reactions were observed, and subgroup analyzed.

RESULTSTo May 31, 2014, all patients reached the clinical endpoint. TTP was 3.5 months (95% Cl: 3.30-4.10) in the treatment group, better than that (2.5 months, 95% CI: 2.32-2.68) of the control group (P < 0.05). DCR was 36.7% in the treatment group and 30.0% in the control group (P > 0.05). OS was 5.2 months (95% CI: 4.53-5.87) in the treatment group and 4.6 months (95% CI: 4.06-5.14) in the control group (P > 0.05). The PS scale was 1.60 ± 0.10 after treatment, lower than that (1.80 ± 0.09) before treatment in the treatment group (P < 0.05). When the PS scale was 0-2 or Child-Pugh scale was class A, TTP was longer in the treatment group than in the control group (P < 0.05). No adverse reaction occurred in the two groups during the treatment course.

CONCLUSIONSThe combination of JLYF with ClK cell treatment could prolong advanced HCC patients' TTP, improve PS scale, as compared with syndrome typed Chinese medical decoction treatment group. Besides, when the PS scale was 0-2 or Child-Pugh scale was class A, it was a better treatment program for advanced HCC patients.

ObjectiveTo investigate the mental health of pediatricians in Guangzhou and its influencing factors， and to provide countermeasures for improving the mental health of pediatricians. MethodsA stratified random sampling method was used to randomly select 400 pediatricians in 11 districts of Guangzhou， and they were surveyed using the Symptom Check List（SCL-90） and the Job Stressor Scale. ResultsThe top three job stressors scored by pediatricians in Guangzhou were external environment （3.23±0.59）， workload （3.19±0.56）， and organizational management （2.74±0.55）. All factor scores were higher than those of the clinician group except for career interest， and the difference was statistically significant （P<0.01）. The number of pediatricians with mental health problems was 109， accounting for 27.25%. All factor scores were higher than the physician norm except for anxiety and paranoia. The correlations between each factor of work stressors and each factor of SCL-90 were positive and statistically significant （P<0.05）， except for two pairs of factors， workload and terror as well as external environment and terror. The results of univariate analysis showed statistically significant differences in the mental health scores of pediatricians with different health status， years of work experience， job satisfaction， job stress， and career prospects （P<0.05）. The results of multiple linear regression showed that health status， years of work experience， professional interest， interpersonal relationship， and doctor-patient relationship were influential factors in the mental health of pediatricians （P<0.05）. ConclusionThe mental health of pediatricians in Guangzhou is unsatisfactory， and the factors affecting them are mainly external objective factors such as workload and organizational management.

Objective: To evaluate the long-term outcomes, failure patterns and prognostic factors of definitive radiotherapy in patients with cervical esophageal carcinoma (CEC). Methods: We retrospectively reviewed the clinical data of 148 CEC patients who treated with definitive radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2001 to December 2017. The median radiation dose was 66 Gy (59.4-70 Gy) and 33.1% of patients received concurrent chemotherapy. The Kaplan-Meier method was used to calculate survival rates. The log rank test was used for survival comparison and univariate prognostic analysis. The Cox model was used for multivariate prognostic analysis. Results: The median follow-up time was 102.6 months. The median survival time, 2- and 5-year overall survival (OS) were 22.7 months, 49.9% and 28.3%. The median, 2- and 5-year progression-free survival were 12.6 months, 35.8% and 25.8%. The 2- and 5-year locoregional recurrence-free survival were 59.1% and 50.8%. The 2- and 5-year distant metastases-free survival were 74.6% and 65.9%. Multivariate analysis showed that EQD(2)>66 Gy was the only independent prognostic indicator for OS (P=0.040). The median survival time and 5-year OS rate significantly improved in patients who received EQD(2)>66 Gy than those who received≤66 Gy (31.2 months vs. 19.2 months, 40.1% vs. 19.1%, P=0.027). A total of 87 patients (58.8%) developed tumor progression. There were 50 (33.8%), 23 (15.5%) and 39 (26.4%) patients developed local, regional recurrence and distant metastases, respectively. Eleven patients (7.4%) underwent salvage surgery, and the laryngeal preservation rate for entire group was 93.9%. Conclusions: Definitive radiotherapy is an effective treatment for cervical esophageal carcinoma with the advantage of larynx preservation. Local recurrence is the major failure pattern. EQD(2)>66 Gy is associated with the improved overall survival.
