RESUMEN
Silicone oil insertion is a common modality in vitreoretinal surgeries after ocular perforating injury. It needs surgical removal after several months. Extraocular silicone oil migration to orbit and eyelid is uncommon complication. We reports a case of silicone oil migration to orbit and eyelid. A 41-year-old male presented with left upper eyelid swelling following silicone oil injection 3 years before admission. Orbital computed tomography scan showed multiple high-density well-defined masses in vitreous, left upper eyelid and orbit. We diagnosed the patient with orbital and eyelid mass, meanwhile, speculated mechanical ptosis. Excision of orbital and eyelid masses were performed. Cystic spaces with delicate fibrous wall and small vessels, and clear fluid in cyst were discovered on histologic examination. The patient was followed up after 1 week. The left upper eyelid slightly depressed and the mechanical ptosis was significantly improved.

Objective: To investigate the treatment options for breast cancer patients aged 65 and over, and analyze the influencing factors. Methods: The clinical data of 521 elderly patients aged 65 years or older,who underwent surgery in Peking Union Medical College Hospital from January 2009 to December 2015, were collected. They were all female and 65-98 years old. The patients were divided into 65-74 years old group (n=353) and ≥ 75 years old group (n=168). The differences of variables including age, functional status, treatment methods, pathological characteristics, comorbidities and survival time between the two groups were compared, and the differences of comprehensive treatment methods and their impact on clinical efficacy were analyzed. Results: The main operation methods of the two groups were modified radical mastectomy [39.1% (138/353) and 33.9% (57/168), respectively], breast conserving surgery [56.9% (201/353) and 61.3% (103/353), respectively]. Among the patients choosing adjuvant therapy, there was no significant difference between the two groups except chemotherapy (all P>0.05). Univariate analysis showed that the choice of chemotherapy was related to age, surgical methods, pathological types, tumor burden, molecular typing, functional status and comorbidities (all P<0.05). The Eastern Cooperative Oncology Group (ECOG) score and the number of comorbidities were independent factors affecting the choice of chemotherapy for breast cancer in the elderly: [ECOG score: adjusted OR=0.45 (95CI: 0.26-0.75), number of comorbidities: adjusted OR = 0.63 (95CI:0.41-0.98); all P<0.05]. The 5-year disease-free survival rate of 521 elderly patients with breast cancer was 86.3%, 5-year overall survival rate was 88.8%, and the breast cancer specific survival rate was 94.3%. Conclusions: The comprehensive treatment of breast cancer patients aged 65 and above is not affected by age, but is associated with tumor burden, pathological type, molecular typing, comorbidities and ECOG score. Among them, ECOG score and the number of comorbidities are the independent factors influencing the choice of adjuvant chemotherapy.

Objective: To compare the population characteristics, the positive rate of screening, the detection rate of breast cancer, early diagnosis rate and the cost between the mass screening group and opportunistic screening group of breast cancer. Methods: This study is a prospective multicenter cohort study conducted from January 1, 2014 to December 31, 2016. The participants were enrolled for mass screening or opportunistic screening of breast cancer. After completing the questionnaire, all the participants received breast physical examination and breast ultrasound examination every year for 3 rounds by year. The participants' characteristics and screening results of the two groups were compared by χ2 test, Fisher exact test or Wilcoxon rank-sum test. Results: A total of 20 080 subjects were enrolled. In the mass screening group, 9 434 (100%), 8 111 (85.98%) and 3 940 (41.76%) cases completed the 3 rounds of screening, and 10 646 (100%), 6 209 (58.32%) and 2 988 (28.07%) cases in the opportunistic screening group, respectively. In the opportunistic screening group, the proportions of less than 3 months lactation (1 275/9 796 vs. 1 061/8 860, χ²=4.597, P=0.032), non-fertility (850/10 646 vs. 574/9 434, χ²=27.400, P<0.01), abortion history (6 384/10 646 vs. 5 062/9 434, χ²=81.232, P<0.01), postmenopausal (2 776/10 646 vs. 2 217/9 434, χ²=17.757, P<0.01), long-term oral contraceptives(>6 months) (171/10 646 vs. 77/9 434, χ²=25.593, P<0.01) and family history of breast cancer in first-degree relatives (464/10 646 vs. 236/9 434, χ²=51.257, P<0.01) were significantly higher than those in mass screening group. The positive rate of screening (514/10 646 vs. 128/9 434, χ²=194.736, P<0.01), the detection rate of breast cancer (158/10 646 vs. 13/9 434, χ²=107.374, P<0.01), and positive rate of biopsy (158/452 vs. 13/87, χ²=13.491, P<0.01) in the opportunistic screening group were significantly higher than those of the mass screening group. The early diagnosis rate of the mass screening group was significantly higher than the opportunistic screening group (10/12 vs. 66/141, χ²=5.902, P=0.015). The average cost for detecting each breast cancer case of the mass screening group was 215 038 CNY, which was 13.6 times of the opportunistic screening group (15 799 CNY/case). In the opportunistic screening group, the positive rate of biopsy in primary hospitals was significantly lower than that in large-volume hospitals (79/267 vs. 79/185, χ²=8.267, P=0.004), but there was no significant difference in the mass screening group (6/37 vs. 7/50, χ²=0.082, P=0.774). Conclusions: Breast cancer screening can improve early detection rate. Compared with the mass screening mode, the opportunistic screening mode has the advantages of higher proportion of high-risk factors, higher positive rate of screening, higher detection rate of breast cancer, higher positive rate of biopsy, and lower cost of screening. However, the early diagnosis rate of breast cancer of opportunistic screening is lower than that of mass screening. The positive rate of opportunistic screening in primary hospitals is lower than that of large-volume hospitals. The two screening modes have their own advantages and should be chosen according to local conditions of different regions in China.

Early hemoperfusion in poisoned patients can remove poisons rapidly and effectively, which plays an important role in improving the prognosis of patients. The key of hemoperfusion therapy is the safe and effective anticoagulation. The local citrate anticoagulation effect acid is good, it also has little effect on the systemic coagulation mechanism and internal environment of patients, so it is worthy of promotion. We retrospectively analyzed the clinical data and treatment of 273 patients who were poisoned by citrate anticoagulant in the emergency intensive care unit of the Second Affiliated Hospital of Shandong First Medical University, aiming at perfusion of citrate anticoagulant in patients with poisoning. Provide a certain clinical reference.

Objective: To explore the association between the 21-gene recurrence score (RS) and clinicopathologic characteristics as well as prognosis in patients with axillary lymph node negative, hormone receptor (HR) positive breast cancer. Methods: The clinicopathologic data of 439 early breast cancer patients who underwent 21 gene RS testing was retrospectively analyzed. According to the 21 gene RS, the patients were divided into low risk (295 cases), intermediate risk (111 cases) and high-risk (33 cases) group. The relationship between the 21 gene RS and clinicopathological characteristics, treatment, recurrence and metastasis was analyzed. Univariate and multivariate statistical analyses were used to analyze the risk factors for relapse free survival (RFS). Results: Tumor grade, estrogen receptor (ER), progesterone receptor (PR) and Ki-67 index were significantly different among the 3 risk cohorts (P<0.001 for all). After a median follow-up of 32 months, the recurrence rate in low risk group (3.7%) was significantly lower than that in the intermediate-high risk group (9.0%), the locoregional recurrence (LRR) rate of low, intermediate and high risk group was 2.4%, 6.3% and 9.1%; and the distant metastasis (DM) rate in low risk group was 1.4% and 2.1% in the intermediate-high risk group. Univariate analysis showed RS, ER status and endocrine therapy were prognostic factors for RFS (P<0.05 for all). Multivariate analysis showed that RS was an independent significant predictor for RFS (P=0.04). Conclusions: The 21-gene RS is related to tumor grade, ER, PR and Ki-67 index. RS is an independent risk factor for RFS in patients with hormone receptor positive early-stage breast cancer.

Objective: To investigate the clinical effect of plasma exchange (PE) versus double plasma molecular adsorption system combined with PE (DPMAS+PE) in the treatment of toxic hepatic failure. Methods: A total of 67 patients with toxic hepatic failure who were admitted during the same period of time were divided into PE group, DPMAS+ PE group, and control group. The 22 patients in the PE group were treated with PE alone, and the 24 patients in the DPMAS+PE group were given DPMAS combined with PE. The clinical out-come was compared between the three groups. Results: Both treatment groups had significantly higher clinical response rate and 24-week survival rate than the control group. After treatment, both treatment groups had significant reductions in the serum levels of total bilirubin (TBil) , direct bilirubin (DBil) , alanine aminotransfer-ase (ALT) , and aspartate aminotransferase (AST) , and the PE group had significant reductions in the albumin (Alb) level and activated partial thromboplastin time (APTT) (P<0.05) ; the DPMAS+PE group showed no sig-nificant changes in the Alb level and APTT (P>0.05). There were no significant differences in TBil, DBil, ALT, and AST between the two treatment groups after treatment (P>0.05). After treatment, the PE group had significantly higher Alb level and APTT than the DPMAS + PE group (P<0.05). Compared with the control group, both treatment groups had significant reductions in TBil, DBil, ALT and AST after treatment (P<0.05). Conclusion: The two artificial liver support techniques can significantly improve patients' liver function and in-crease their survival rate, and the combined artificial liver support technique can reduce the amount of plasma used.

Objective: To explore the effectiveness and feasibility of conscious sedation with a low dose of dexmedetomidine and sufentanil during multiple intestinal polyps resection in elderly patients. Methods: Sixty elderly patients who underwent multiple intestinal polyps resection in Peking University Third Hospital from Janurary to May 2016 were randomly divided into dexmedetomidine group (D group, n=30) and propofol group (P group, n=30). There were 28 males and 32 females with a mean age of (70.4±4.5) years old (range: 65-80 years old). The patients in the dexmedetomidine group received a loading dose of 0.3 µg/kg followed by a continuous infusion of 0.2-0.4 µg·kg-1·min-1 of dexmedetomidine and sufentanil (0.1 µg/kg) respectively.The patients in the propofol group received sufentanil 0.1 µg/kg and propofol 1.5 mg/kg and followed by a continuous infusion of 3-6 mg·kg-1·h-1 of propofol.Blood pressure, heart rate, pulse oxygen saturation (SpO2), respiratory rate and bispectral index (BIS) were recorded at the basic status and at the beginning of operation, 10 min, 20 min, 30 min after operation, the end of operation and departure.The observer's assessment of alertness/sedation (OAA/S) scores and the clinical responses were also recorded.A statistical analysis was performed. Results: All patients in the two groups were sedated compared with baseline.The BIS values of patients in group D at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation were 89.6(87.8-91.0), 79.4(78.0-80.0), 76.9(75.0-80.0), 76.0(73.0-79.0) and 75.6(70.0-79.0) respectively, and those values were all significantly lower than baseline value[96.4(95.0-98.0)], (Z=-4.645, -4.788, -4.787, -4.789, -4.789, P<0.05). The OAA/S score at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation were 4.5(4.0-5.0), 3.4(3.0-4.0), 3.0(3.0-3.0), 3.5(3.0-4.0) and 3.3(3.0-4.0) respectively, and were significantly lower than baseline score [4.8(5.0-5.0)] (Z=-2.828, -4.862, -5.031, -4.420, -4.710, P<0.05). The BIS value of patients in group P at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation were 54.7(50.0-59.3), 54.8(50.0-59.3), 50.7(47.8-56.8), 54.4(51.5-58.0) and 53.7(50.0-57.3) respectively, and were significantly lower than baseline value[95.8(95.0-96.3)] (Z=-4.786, -4.787, -4.788, -4.786, -4.786, P<0.05). The OAA/S score at beginning of the operation , 10 min, 20 min, 30 min after operation and the end of operation were 0.4(0.0-1.0), 0.4(0.0-1.0), 0.4(0.0-1.0), 0.4(0.0-1.0) and 0.4(0.0-1.0) respectively, and were significantly lower than baseline score[4.9(5.0-5.0)] (Z=-4.927, -4.901, -4.912, -4.912, -4.901, P<0.05). The sedation state of group D were lighter than group P. The BIS value and OAA/S score at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation in group D were higher than group P (P<0.05). The breath and circulation were more stable in group D. The mean arterial pressure, breath rate and SpO2 at beginning of the operation, 10 min, 20 min, 30 min after operation and the end of operation in group D were higher than group P (P<0.05). There was no oxygen desaturation , hypotension and drowsiness in group D and the incidence in group P were 30.0%, 33.3% and 13.3% respectively.The emergency time and duration of stay in the PACU (post anesthesia care unit) were (2.0±1.2) and (22.0±7.4) min in group D, and they were (4.9±2.4) and (35.8±11.6) min in group P (t=-5.839, t=-5.472, P<0.05). There was no difference in surgery time, patient satisfaction and acceptance rate of reexamination (t=-3.031, t=-7.322, t=2.069, P>0.05). Conclusion: Conscious sedation with dexmedetomidine and sufentanil is effective and feasible in elderly patients undergoing multiple intestinal polyps resection.

The 21-Gene Recurrence Score Assay has been intensively studied and recommended by major guidelines for treatment decision in early breast cancer. Its impact in adjuvant chemotherapy selection for Chinese population has not been revealed.The prospective part of this study enrolled consecutive node-negative, hormone receptor-positive patients who underwent 21-gene RS testing at Breast Surgery Department of PUMCH (n=134) between May 2012 and August 2013(21-gene RS group). Risk categories were assigned based on the RS and on standard clinicopathologic criteria according to St. Gallen and Adjuvant! Online. The chemotherapy selection and the oncologists' confidence in decision-making before and after RS testing were recorded. The retrospective part of this study compared the chemotherapy decision in the 21-gene RS group and a control group without RS testing (diagnosed between Jan 2011 and Apr 2012,n=170). A total of 304 patients were included in the analysis (134 21-gene RS group, 170 controls). Based on RS, 97 patients were classified as low risk, 29 patients as intermediate risk, and 8 patients as high risk. Tumor grade (P=0.002), PR expression (P<0.001) and Ki-67 index (P<0.001) were significantly different between the 3 risk cohorts.Comparing the St. Gallen guidelines and RS, there was a 41% concordance between risk groups. By using Adjuvant! Online, the correlation between the predicted BCSM and RS was nominal (r=0.10). A total of 29% 21-gene RS group patients changed their treatment decisions after RS testing (P<0.001, 95% CI, 0.18 to 0.49) with 6% (8/134) patients changing to receive chemotherapy besides endocrine therapy and 23% (31/134) changing to reject chemotherapy. After RS testing, more than one half of the oncologists increased their confidence level in treatment recommendation. In the control group, 67.6% (115/170) patients chose chemotherapy plus endocrine therapy. The chemotherapy percentage was much higher than that of 21-gene RS group (30/134, 22%).This is the first study to demonstrate a reduction in the use of adjuvant chemotherapy in women with node-negative hormone receptor-positive breast cancer, based on use of the RS. The RS had an impact on the physicians' treatment decision-making.
RESUMEN
Ficolin-2 is a kind of human serum complement lectin with a structure similar to mannan-binding lectin (MBL), and it has been implicated in innate immunity. Recent studies have shown that complement pathway activation may contribute to hepatitis. However, the relationship between ficolin-2 and viral hepatitis remains largely elusive. The aim of this study was to determine the dynamics of ficolin-2 in patients with chronic hepatitis C. Forty nine patients who had not yet received therapy [24 patients with abnormal alanine aminotransferase (ALT) levels (>40 U/L) and 25 patients with normal ALT levels (≤ 40 U/L)], 28 patients with hepatitis C who received therapy for 2 weeks and 16 patients received therapy for a full month or longer were included in the study. A sandwich enzyme-linked immunosorbent assay (ELISA) was used to measure the ficolin-2 concentrations in all serum samples of patients and 42 healthy donors. We found the concentrations of ficolin-2 were significantly higher in chronic hepatitis C patients with abnormal ALT values than in chronic hepatitis C patients with normal ALT values and healthy controls. Ficolin-2 concentrations in chronic hepatitis C patients with abnormal ALT values were positively correlated with ALT levels (P < 0.05). After therapy, the concentrations of ficolin-2 decreased and accompany with ALT and Hepatitis C virus (HCV) RNA levels. Then, we found ficolin-2 concentrations in rapid viral response (RVR) group decreased significantly (P < 0.05), while in non-RVR group, ficolin-2 decreased slightly (P > 0.05). Our findings suggest that early increased ficolin-2 is highly correlated with hepatic inflammation and rapid viral response.

In the present study, we examined the neural mechanisms underlying cross-modal working memory by analyzing scalp-recorded event-related potentials (ERPs) from normal human subjects performing tactile-tactile unimodal or tactile-auditory cross-modal delay tasks that consisted of stimulus-1 (S-1, tactile), interval (delay), and stimulus-2 (S-2, tactile or auditory). We hypothesized that there would be sequentially discrete task-correlated changes in ERPs representing neural processes of tactile working memory, and in addition, significant differences would be observed in ERPs between the unimodal task and the cross-modal task. In comparison to the ERP components in the unimodal task, two late positive ERP components (LPC-1 and LPC-2) evoked by the tactile S-1 in the delay of the cross-modal task were enhanced by expectation of the associated auditory S-2 presented at the end of the delay. Such enhancement might represent neural activities involved in cross-modal association between the tactile stimulus and the auditory stimulus. Later in the delay, a late negative component (LNC) was observed. The amplitude of LNC depended on information retained during the delay, and when the same information was retained, this amplitude was not influenced by modality or location of S-2 (auditory S-2 through headphones, or tactile S-2 on the left index finger). LNC might represent the neural activity involved in working memory. The above results suggest that the sequential ERP changes in the present study represent temporally distinguishable neural processes, such as the cross-modal association and cross-modal working memory.

Fast excitatory synaptic transmission through vertebrate autonomic ganglia is mediated by postsynaptic nicotinic acetylcholine receptors (nAChRs). We demonstrate a unique postsynaptic receptor microheterogeneity on chick parasympathetic ciliary ganglion neurons-under one presynaptic terminal, nAChRs and glycine receptors formed separate but proximal clusters. Terminals were loaded with [3H]glycine via the glycine transporter-1 (GlyT-1), which localized to the cholinergic presynaptic terminal membrane; depolarization evoked [3H]glycine release that was calcium independent and blocked by the GlyT-1 inhibitor sarcosine. Ganglionic synaptic transmission mediated by nAChRs was attenuated by glycine. Coexistence of separate clusters of receptors with opposing functions under one terminal contradicts Dale's principle and provides a new mechanism for modulating synaptic activity in vivo.

PURPOSE: Because of its aggressive characteristics and poor prognosis, triple-negative breast cancer (TNBC) has become a hot topic in cancer research. Chemotherapy is currently the only treatment for patients with TNBC. The transcription factor FOXC1 has been associated with TNBC prognosis, but little is known about its effect on chemosensitivity. The aim of this study was to investigate the effects of FOXC1 on chemosensitivity. METHODS: A case-control study was performed on 25 TNBC patients who experienced relapse and/or metastasis. Another 25 patients without relapse or metastasis were randomly selected as controls. Medical records were reviewed for relevant information, and immunohistochemistry was performed to measure FOXC1 levels. The Kaplan-Meier method and Cox analysis were used to analyze differences in disease-free survival (DFS) and overall survival (OS). The correlation of FOXC1 expression with chemosensitivity was analyzed. Data were analyzed using SPSS 21.0 software, and a P value <0.05 was considered to be statistically significant. RESULTS: In 15 of 22 case patients, FOXC1 was overexpressed, whereas only 8 control patients exhibited FOXC1 overexpression (P < 0.05). FOXC1 expression had no correlation with pathological indicators. An anthracycline-based regimen was administered to 21 study patients and 23 control patients. FOXC1 expression was significantly associated with a worse DFS (HR 2.62, 95% CI 1.05-6.50, P = 0.038) but presented no correlation with OS (HR 2.53, 95% CI 0.76-8.40, P = 0.131) among these 44 patients. CONCLUSIONS: This study shows that FOXC1 is correlated with chemosensitivity to anthracycline and could be used as an indicator of chemosensitivity in sporadic TNBC.
