RESUMEN
Objective To report a case of synovial sarcoma of the liver and review the literature for improving the understanding of the disease.Methods The clinical data of a patient with liver synovial sarcoma admitted to the First Affiliated Hospital of Henan University were analyzed retrospectively.The imaging,pathological features,treatment and prognosis of this disease were summarized by searching the database(CNKI,Wanfang Data,PubMed,untill July 2022)and the literature results analyzed comprehensively.Results The patient was a 71-year-old female who was admitted to the hospital due to abdominal pain.Computed tomography(CT)scan showed a mass with mixed density in the right lobe and caudate lobe of the liver.The large cross section size was about 115 mm×87 mm and the mass showed continuous heterogeneous enhancement,being considered as malignant hepatic tumors with multiple metastasis of the liver and lung.Ultrasound-guided needle biopsy was performed,and microscopy showed the tumor cells were obvious atypical,and some were spindle-shaped.Immunohistochemistry showed that the patient was positive for vimentin(VIM),epithelial membrane antigen(EMA),methylation of histone at lysine 27(H3K27Me3),and negative for pan cytokeratin(CK-pan)and S-100,and pathological diagnosis of synovial sarcoma was made.The patient did not undergo subsequent treatment and was lost to follow-up after discharge.A total of 12 cases of hepatic synovial sarcoma were reported after searching the database.The clinical manifestations were abdominal pain or distention.The lesions were mostly located in the right lobe of the liver,usually large,heterogeneous density,and heterogeneous enhancement on enhanced CT or magnetic resonance imaging(MRI).Spindle-shaped cells were found at histopathologic examination.Immunohistochemistry showed the patient was positive for VIM,EMA,H3K27Me,B-cell leukemia/lymphoma-2(BCL-2)and transducer-like enhancer of split 1(TLE1).SS18-SSX fusion gene or SS18 gene isolation were detected.Eleven patients received surgical treatment,5 received adjuvant chemotherapy,and 4 had recurrence or metastasis during the follow-up period.Conclusions Synovial sarcoma of the liver is a rare malignant tumor of the liver.The clinical and imaging features are not specific.The diagnosis depends on pathology.At present,the main treatment is surgery,and comprehensive treatment such as adjuvant chemotherapy can be performed.The prognosis of the patient is poor.
RESUMEN
@#Objective To explore whether surgery combined with adjuvant chemotherapy can bring survival benefits to patients with cervical and upper thoracic esophageal squamous cell carcinoma (ESCC). Methods The clinical data of patients with cervical and upper thoracic ESCC who underwent R0 resection and neck anastomosis in our department from 2006 to 2010 were retrospectively analyzed. Patients received neoadjuvant therapy or adjuvant radiotherapy were excluded. The adjuvant chemotherapy group was given a combination of taxanes and platinum based chemotherapy after surgery; the surgery alone group did not receive adjuvant chemotherapy. The Kaplan-Meier method was used to analyze the survival difference between the adjuvant chemotherapy group and the surgery alone group. Results A total of 181 patients were enrolled, including 141 (77.9%) males and 40 (22.1%) females, with an average age of 61.0±8.2 years (80 patients aged≤61 years, 101 patients aged>61 years). There were 70 (38.7%) patients of cervical ESCC, and 111 (61.3%) patients of upper thoracic ESCC. Eighty-seven (48.1%) patients underwent postoperative adjuvant chemotherapy, and 94 (51.9%) patients underwent surgery alone, and the basic clinical characteristics were well balanced between the two groups (P>0.05). The median survival time of patients in the adjuvant chemotherapy group and the surgery alone group was 31.93 months and 26.07 months, and the 5-year survival rate was 35.0% and 32.0%, respectively (P=0.227). There was no statistical difference in median survival time between the cervical ESCC and upper thoracic ESCC group (31.83 months vs. 29.76 months, P=0.763). For cervical ESCC patients, the median survival time was 45.07 months in the adjuvant chemotherapy group and 14.70 months in the surgery alone group (P=0.074). Further analysis showed that the median survival time of lymph node negative group was 32.53 months, and the lymph node positive group was 24.57 months (P=0.356). The median survival time was 30.43 months in the lymph-node positive group with adjuvant chemotherapy and 17.77 months in the lymph-node positive group with surgery alone. The survival curve showed a trend of difference, but the difference was not statistically significant (P=0.557). Conclusion There is no statistical difference in the long-term survival of cervical and upper thoracic ESCC patients after R0 resection. Postoperative adjuvant chemotherapy may have survival benefits for patients with cervical ESCC and upper ESCC with postoperative positive lymph nodes, but the differences are not statistically significant in this setting.
RESUMEN
Traumatic brain injury (TBI) triggers the activation of the endogenous coagulation mechanism, and a large amount of thrombin is released to curb uncontrollable bleeding through thrombin receptors, also known as protease-activated receptors (PARs). However, thrombin is one of the most critical factors in secondary brain injury. Thus, the PARs may be effective targets against hemorrhagic brain injury. Since the PAR1 antagonist has an increased bleeding risk in clinical practice, PAR4 blockade has been suggested as a more promising treatment. Here, we explored the expression pattern of PAR4 in the brain of mice after TBI, and explored the effect and possible mechanism of BMS-986120 (BMS), a novel selective and reversible PAR4 antagonist on secondary brain injury. Treatment with BMS protected against TBI in mice. mRNA-seq analysis, Western blot, and qRT-PCR verification in vitro showed that BMS significantly inhibited thrombin-induced inflammation in astrocytes, and suggested that the Tab2/ERK/NF-κB signaling pathway plays a key role in this process. Our findings provide reliable evidence that blocking PAR4 is a safe and effective intervention for TBI, and suggest that BMS has a potential clinical application in the management of TBI.
RESUMEN
To compare the short-term and long-term results of thoracoscopic and open pneumonectomy for non-small cell lung cancer. The clinical data of patients with non-small cell lung cancer who underwent pneumonectomy in the Department of Thoracic Surgery, Qingdao University Hospital from January 2008 to December 2016 were collected. Totally 142 patients (55 in the thoracoscopic group and 87 in the open group) were included in the study. A total of 29 pairs of patients were successfully matched by propensity score matching (PSM). Perioperative outcomes and overall survival were compared between the two groups using test, χ(2) test, Kaplan-Meier curve and Log-rank test, respectively. Camparion with open group, the thoracoscopic group had longer operative time ((209.7±70.2) minutes . (171.3±43.5) minutes, 2.50, 0.02), more mediastinal lymph node dissection ((): 17(9) . 11(10), =388, 0.02) and shorter postoperative hospital stay (7.0(3.5) . 9.0(3.0), =285, 0.03). There was no significant difference in estimated blood loss, postoperative drainage time, dissected lymph node number, dissected lymph node station and perioperative complications. After PSM, there were no signifificant differences found in 3-year survival (71.4% . 48.1%, 0.10) and 3-year disease-free survival (67.4% . 47.2%, 0.13) between the two groups. Thoracoscopic pneumonectomy is safe and feasible for the treatment of non-small cell lung cancer with more mediastinal lymph node dissection and accelerating recovery, and equivalent long-term prognosis when compared with open approach.
RESUMEN
OBJECTIVE@#To study and compare the effect of indwelling drainage tube and extubation time on occult hemorrhage and functional recovery after total hip arthroplasty(THA).@*METHODS@#From July 2017 to June 2018, 123 patients who underwent THA in our hospital for the first time were selected as the subjects of study. According to whether the drainage tube was retained or not and the time of extubation, they were divided into three groups:in group A, 41 patients (24 males, 17 females, age 53 to 77 years) did not put drainage tube after THA;in group B, 41 patients were removed 24 hours after THA, 26 males and 15 females, aged 55 to 74 years;in group C, 41 patients were removed 48 hours after THA, 25 males and 16 females, aged 52 to 75 years. The VAS score of pain 72 hours after THA, the total and recessive blood loss, the time of starting functional exercise, and the incidence of postoperative limb swelling were recorded. All the patients were followed up for one year after discharge. Harris hip score was used to evaluate the degree of hip function recovery one year after operation.@*RESULTS@#The occult blood loss of group A, B and C were(513.6±25.3), (521.7±33.4), (519.3±29.8) ml, respectively, with no significant difference(>0.05). There was no significant difference in blood loss in operation among the three groups(>0.05). In group B and C, the postoperative apparent blood loss was more than that in group A (0.05). The time of getting out of bed in group A was shorter than that in group B and C (0.05). There was no significant difference in the incidence of complications among three groups (>0.05).@*CONCLUSION@#Whether the drainage tube is left or not and the time of extubation have no significant effect on the latent blood loss and functional recovery after THA, but without drainage tube after THA can reduce the apparent blood loss, patients can get out of bed at 6 hours after THA, which is more conducive to the recovery and nursing of patients.

OBJECTIVE: To improve the method for the content determination of astragaloside Ⅳ in Xiangju granules, and to evaluate the consistency of relevant preparations with the components of original formulation, so as to provide evidence for the modern preparation of TCM compound. METHODS: HPLC-ELSD method was established for the content determination of astragaloside Ⅳ in Xiangju granules, and compared with original standard TLC scanning. Using critrinin, ferulic acid, calycosin glucoside, liquiritin, glycyrrhizic acid, rosmarinic acid, buddleoside and magnoline as control, HPLC method was used to determine the release components of self-made Xiangju granules, Xiangju capsules, Xiangju tablets in water. Fingerprint characteristics chromatogram of different Xiangju preparations and original formulation extract were compared by using Similarity Evaluation System for Chromatographic Fingerprint of TCM (2012 version). At the same time, HPLC-ELSD method was used to determine and compare the release rate of astragaloside Ⅳ from different Xiangju preparations and original formulation extract in water. RESULTS: Established HPLC-ELSD method was specific. The linear range of astragaloside Ⅳ was 0.13-2.10 mg/mL. RSDs of precision, repeatability and stability tests were all lower than 3% (n=6), and average recovery was 97.66% (RSD=1.01%,n=6). Average content of astragaloside Ⅳ by this method was 0.398 mg/g (RSD=1.01%, n=3), which had better reproducibility than TLC scanning. The comparative results of characteristic fingerprints showed that the similarity among Xiangju granules, Xiangju capsules, Xiangju tablets and the original formulation dry extract powder was more than 0.850. Average release rates of astragaloside Ⅳ in Xiangju granules, Xiangju capsules, Xiangju tablets and the original formulation extract were 0.392, 0.358, 0.349, 0.389 mg, respectively. Compared with original formulation extract, there was no statistical significance in release rate of astragaloside Ⅳ in Xiangju granules (P>0.05), while there was statistical significance in Xiangju capsules and Xiangju tablets (P<0.01). CONCLU- SIONS: Established HPLC-ELSD method is accurate and feasible, and is suitable for the content determination of astragaloside Ⅳ in Xiangju granules. The main components of Xiangju granules are consistent with original formulation.

RESUMEN
<p><b>OBJECTIVE</b>To investigate the effects of mannan-binding lectin (MBL) on the maturation and cytokine secretion of human dendritic cells (DC) induced by Candida albicans (C. albicans).</p><p><b>METHODS</b>The plastic-adherent mononuclear cells were prepared from the blood of healthy adult volunteers. The human peripheral blood mononuclear cells-derived dendritic cells (MNC-DC) were induced by 5-day-culture in medium supplemented with rhGM-CSF and rhIL-4, and then cultured for 2 days in presence or absence of C. albicans at varying concentration of human MBL ranging from 1 to 20 mg/L. DC's shape and characters were observed under inverted microscopy, the expression of CD83 and CD86 on DC was analyzed by FACS. The levels of TNF-α and IL-6 were detected by ELISA. FACS also was used to investigate the interaction of MBL with immature DC(imDC) and C. albicans. Western blot was used to detect C. albicans-induced IκBα phosphorylation and p65/NF-κB translocation in DC.</p><p><b>RESULTS</b>MBL at higher concentrations (10-20 mg/L) down-regulated the expression of CD83 and CD86 on the monocyte-derived dentritic cells(MoDC) induced by C. albicans, and inhibited the production of TNF-α and IL-6 induced by C. albicans. FACS showed that MBL could not only bind to C. albicans but also bind to imDCs in a Ca2+-dependent manner. Western blot showed that MBL could decrease the phosphorylation of IκBα and the nuclear translocation of p65/ NF-κB.</p><p><b>CONCLUSION</b>MBL may inhibit TNF-α and IL-6 production induced by C. albicans in DC through NF-κB signaling pathways, suggesting that MBL can play some roles in the regulation of C. albicans-induced immune response.</p>

Epidermal growth factor receptor (EGFR) gene mutation and copy number are useful predictive markers that guide the selection of non-small cell lung cancer (NSCLC) patients for EGFR-targeting therapy. This study aimed to investigate the correlation between EGFR gene mutation and copy number and clinicopathologic characteristics of Chinese patients with NSCLC. NSCLC specimens collected from 205 patients between November 2009 and January 2011 were selected to detect EGFR gene mutations with real-time polymerase chain reaction (RT-PCR) and to detect EGFR gene copy number with fluorescence in situ hybridization (FISH). EGFR mutations primarily occurred in females, non-smokers, and patients with adenocarinomas (all P < 0.001). Tissues from 128 (62%) patients were FISH-positive for EGFR, including 37 (18%) with gene amplification and 91 (44%) with high polysomy. EGFR gene mutation was correlated with FISH-positive status (R = 0.340, P < 0.001). Multivariate analysis showed that not smoking (OR = 5.910, 95% CI = 2.363-14.779, P < 0.001) and having adenocarcinoma (OR = 0.122, 95% CI = 0.026-0.581, P = 0.008) were favorable factors for EGFR gene mutation. These results show a high frequency of EGFR FISH positivity in NSCLC tissues from Chinese patients and a significant relevance between EGFR gene mutations and FISH-positive status. Among the FISH-positive samples, EGFR gene mutation occurred more frequently in samples with gene amplification compared to those with high polysomy, suggesting that EGFR mutation and gene amplification should be used as clinical decision parameters to predict response to EGFR-targeting therapy.

Response criteria remain controversial in therapeutic evaluation for locally advanced esophageal carcinoma treated with neoadjuvant chemotherapy. We aimed to identify the predictive value of tumor regression grading (TRG) in tumor response and prognosis. Fifty-two patients who underwent neoadjuvant chemotherapy followed by esophagectomy and radical 2-field lymphadenectomy between June 2007 and June 2011 were included in this study. All tissue specimens were reassessed according to the TRG scale. Potential prognostic factors, including clinicopathologic factors, were evaluated. Survival curves were generated by using the Kaplan-Meier method and compared with the log-rank test. Prognostic factors were determined with multivariate analysis by using the Cox regression model. Our results showed that of 52 cases, 43 (83%) were squamous cell carcinoma and 9 (17%) were adenocarcinoma. TRG was correlated with pathologic T(P = 0.006) and N (P < 0.001) categories. Median overall survival for the entire cohort was 33 months. The 1- and 2-year overall survival rates were 71% and 44%, respectively. Univariate survival analysis results showed that favorable prognostic factors were histological subtype (P = 0.003), pathologic T category (P = 0.026), pathologic N category (P < 0.001), and TRG G0 (P = 0.041). Multivariate analyses identified pathologic N category (P < 0.001) as a significant independent prognostic parameter. Our results indicate that histomorphologic TRG can be considered as an alternative option to predict the therapeutic efficacy and prognostic factor for patients with locally advanced esophageal carcinoma treated by neoadjuvant chemotherapy.

Objective To assess the safety and efficacy of an olive oil-based lipid emulsion for parenteral nutrition in patients after esophagectomy.Methods In the randomized controlled trial,60 patients undergoing esophagectomy were divided into study group(n=30,received olive oil-based lipid emulsion)and control group [n=30,received medium-chain triglyceride/long-chain triglyceride(MCT/LCT)emulsion].The parenteral nutrition Was provided for 7-10 postoperative days.The nutritional formulas were equivalent in nitrogen,calorie,osmotic pressure,and fluid volume.Peripheral venous blood tests were performed before operation and on the first and eighth postoperative days.All the patients were evaluated by nutritional status(weight,body mass index,nutritional risk screening,etc.),safety profiles[full blood test,electrolytes,aspartate aminotransferase(AST),alanine amiotransferase(ALT),total bilirubin and direct bilirubin,blood urea nitrogen(BUN),creatinine,blood glucose,etc.],and efficacy indicators(hemoglobin,albumin,total protein,etc.).Results The albumin and total protein levels returned to the normal ranges in beth groups 8 days after operation,although both levels were significantly higher in study group(P=0.000).Also,the difference of total protein levels between the eighth and first postoperative days Was significantly higher in the study group(P=0.002).In addition,the AST and BUN readings returned to normal ranges 8 days after operation in the study group, which were significantly lower than those in control group (P = 0.025, P = 0.013).No serious adverse events were reported in both groups.Other nutritional parameters, renal and hepatic safety profiels, vital signs, and hematology showed no significant difference between two groups.Conclusions Olive oil-based lipid emulsion is a safe and efficient lipid emulsion for parenteral nutrition in patients undergoing esophagectomy.Compared with MCT/LCT, it has less effect on AST and BUN.
RESUMEN
Objective To build a bio-material artificial chest wall and discuss its feasibility and efficiency in reconstruction of huge bony defects of chest wall in mongrels in comparison with traditional "sandwich" procedure. Methods (1) The procine osteal and membranate tissues were treated with epoxy cross linking method and their surfaces were modified with amino acid solutions at various concen-trations and at different temperatures to obtain an artificial pleura and artificial ribs for construction of the artificial chest wall. (2) The huge bony defects (5 cm×5 cm) were created in chest wall of five Chinese mongrels. (3) Three mongrels in test group was repaired with artificial chest wall, while two mongrels in control group was repaired with traditional "sandwich" complex. A follow-up was carried out to observe reconstruction effect and rejection in both groups at 3,6 and 12 months after implantation. Results There was no death found during the perioperative period and at 12 month follow-up in test group, with abnormal contour of chest wall and good thoracic activity after reconstruction. In the meantime, there found no rejection, collapse in the repaired region or paradoxical respiration. The postoperative X-rays at 3,6,12 and 24 months showed a good integrity of the thorax, with no collapse, deformation or abnormal movement. Meanwhile, the follow-up of control group showed a normal contour but slight collapse, with no paradoxical respiration. The Chest X-ray examination revealed that the bone cement in" sandwich" complex was X ray opaque and showed mild abnormal movement with breathing. The common blood test and immune items showed no abnormal. Conclusions The bio-material artificial chest wall is a safe and effective reconstruction technique for bony defects of thoracic wall in mongrels, with no acute or chronic rejection.
