Radiotherapy concurrent with a 3-week schedule of PTX and DDP resulted in an encouraging overall survival rate, but a relatively higher hematological toxicity.

Multiple organ dysfunction syndrome (MODS) is an important cause of morbidity and mortality in intensive care unit. A severe insult in the form of infection or trauma primes the host immune system so that a subsequent, relatively trivial insult produces systemic inflammation response syndrome, which can lead to MODS and death. Matrix metalloproteinase-9 (MMP-9) is stored in the tertiary granules of polymorphonuclear leukocytes. These cells are key effectors in acute inflammatory diseases, such as sepsis and MODS. Endotoxin leads to rapid release of MMP-9 from these granules in vitro and in vivo. However, the role of this enzyme in MODS, and whether it is associated with organ injury at the early stage of MODS remains unclear. This present work may study role of MMP-9 with the MODS rats that caused by trauma and infection and investigate the mechanism of organ injury at the early stage of MODS. Here, we developed a rat model for MODS caused by trauma and infection and analyzed the dynamic level of MMP-9 and determined the relationship between MMP-9 level and early phase of organ injury in MODS rat. The histological changes in pulmonary, renal, and hepatic tissue were observed by light microscope. The expressions of plasma MMP-9 proteins were detected by an enzyme linked immunosorbent assay and its levels in the pulmonary, renal, and hepatic tissue were detected by using immunohistochemistry, respectively. The results indicated that there were no significant improvements in histopathology of rats in control group. However, the pulmonary, renal, and hepatic damage were serious in MODS groups. The concentration of MMP-9 in plasma and tissues of MODS rats increased markedly at the early stage and were higher than that of the control group. Moreover, the MMP-9 level in plasma positively correlated with the levels of pulmonary, renal, and hepatic tissue. This study clearly shows that MMP-9 is good biomarker to predict the severity of injury organ at the early phase of MODS.

BACKGROUND:The thoracic radiotherapy (TRT) target volume for limited-stage small-cell lung cancer (SCLC) has been controversial for decades. In this report, the final results of a prospective randomized trial on the TRT target volume before and after induction chemotherapy are presented. METHODS: After 2 cycles of etoposide and cisplatin, patients arm were randomized to receive TRT to the postchemotherapy or prechemotherapy tumor volume in a study arm and a control arm. Involved-field radiotherapy was received in both arms. TRT consisted of 1.5 grays (Gy) twice daily in 30 fractions to up to a total dose of 45 Gy. Lymph node regions were contoured, and intentional and incidental radiation doses were recorded. RESULTS: The study was halted early because of slow accrual. Between 2002 and 2017, 159 and 150 patients were randomized to the study arm or the control arm, respectively; and 21.4% and 19.1% of patients, respectively, were staged using positron emission tomography/computed tomography (P = .31). With a median follow-up of 54.1 months (range, 19.9-165.0 months) in survivors, the 3-year local/regional progression-free probability was 58.2% and 65.5% in the study and control arms, respectively (P = .44), and the absolute difference was −7.3% (95% CI, −18.2%, 3.7%). In the study and control arms, the median overall survival was 21.9 months and 26.6 months, respectively, and the 5-year overall survival rate was 22.8% and 28.1%, respectively (P = .26). Grade 3 esophagitis was observed in 5.9% of patients in the study arm versus 15.5% of those in the control arm (P = .01). The isolated out-of-field failure rate was 2.6% in the study arm versus 4.1% in the control arm (P = .46), and all such failures were located in the supraclavicular fossa or contralateral hilum. The regions 7, 3P, 4L, 6, 4R, 5, and 2L received incidental radiation doses >30 Gy. CONCLUSIONS: TRT could be limited to the postchemotherapy tumor volume, and involved-field radiotherapy could be routinely applied for limited-stage SCLC. Cancer 2020;126:840-849.

In conclusion, prophylactic implantation of a drainage tube adjacent to the esophageal anastomosis is a good method for rapid diagnosis and treatment of leakage.

BackgroundMcKeown-type esophagectomy combined with retrosternal reconstruction is a common surgical treatment for esophageal cancer. Various enteral feeding options are available post-esophagectomy, but no definitive preference exists.Method“Retrosternal Route Gastrostomy Feeding (RGF)” was developed as an alternative enteral feeding approach that requires few additional surgical interventions. RGF is based on McKeown-type esophagectomy. We retrospectively compared RGF (n = 121) to jejunostomy feeding (JF) (n = 153) in 274 patients at the Department of Cardiothoracic Surgery in Changzheng Hospital (Shanghai, China) between June 2008 and Sept. 2012. Data pertaining to efficacy and procedural complications were compared among patients.ResultsRGF had a significantly shorter postoperative hospital stay (11 vs. 15 days, p<0.001) and time to removal of the feeding tube (9 vs. 14 days, p<0.001) compared to JF. Bowel obstruction (0.0% vs. 7.2% p = 0.003), abdominal distension (9.1% vs. 19% p = 0.022), and the occurrence of pneumonia (11.6% vs. 26.1% p = 0.003) were significantly lower in the RGF group. Feeding tube related complications and the associated morbidity rate were reduced in the RGF group. The two groups had similar tolerance to surgery.ConclusionOur data suggests that RGF is a safe post-esophagectomy enteral feeding alternative to JF.

Henoch-Schönlein purpura (HSP) is a small-vessel vasculitis mediated by IgA-immune complex deposition. It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura, abdominal pain, arthritis and renal involvement. The diagnosis of HSP is difficult, especially when abdominal symptoms precede cutaneous lesions. We report a rare case of paroxysmal drastic abdominal pain with gastrointestinal bleeding presented in HSP. The diagnosis was verified by renal damage and the occurrence of purpura.

AIMTo evaluate the long-term effectiveness and late toxicities of paclitaxel (PTX) plus cisplatin (DDP) with concurrent radiotherapy for locally advanced esophageal squamous cancer.METHODSBetween 2008 and 2011, 76 patients were enrolled in a phase II study on the treatment of loco-regionally advanced esophageal cancer with radiotherapy (68.4 Gy/44 fractions or 61.2 Gy/34 fractions) combined with 4-cycle chemotherapy consisting of DDP (25 mg/m2 per day for 3 d) and PTX (175 mg/m2 for 3 h). The primary endpoints were overall survival and progression-free survival, and the secondary endpoints were toxicity and the treatment failure pattern.RESULTSA total of 76 patients were enrolled in this study, of whom 63.2% finished the whole regimen. The 5-year survival rates for the per-protocol population and intent-to-treat population were 25.4% and 26.4%, respectively, and the median survival rates were 23.7 mo and 28.5 mo, respectively. Grade 3 or 4 late toxicity was observed in only one patient (heart failure). In log-rank analysis, the pretreatment stage (stage II + III: 36.1 mo vs stage IV: 14.9 mo) and the completed cycle (1-3 cycles: 16.1 mo vs 4 cycles: 35.5 mo) were significant prognostic factors (P = 0.037 < 0.05 and P = 0.013 < 0.05).CONCLUSIONRadiotherapy combined with chemotherapy consisting of PTX and DDP is a safe and effective definitive treatment for loco-regionally advanced esophageal squamous cancer.

The Bohai Strait is a crucial pathway for water exchange between the Bohai Sea and the Yellow Sea, and exhibits a robust spatiotemporal pattern of hydrodynamic conditions. 16S rRNA amplicon sequencing was applied to study the spatiotemporal patterns of bacterial community composition and diversity in the Bohai Strait. Physical and chemical parameters were measured in order to explain what might control the observed patterns in community composition and diversity. In response to environmental changes between seasons, especially the dramatic changes of temperature and nutrient (NO 2-N and PO 4-P) levels, Synechococcus and unclassified genera in Family I predominated in summer while some oligotrophic taxa (e.g., Pelagibacter, OM43 clade) are more abundant in winter. The spatial heterogeneity and overall patchiness of bacterial assemblages in the Bohai Strait could not be well explained by the measured factors. However, the taxa with the most spatially variable presence and absence, e.g. Vibrionaceae, SAR11 and Sva0996 marine group, possess differentiated niches for utilization of organic matter (OM) and display a close relationship with the distribution of OM sources in this area, which may indicate the significance of OM sources to bacterial community structure. Our results suggest that local factors rather than regional factors, such as dispersal limited by hydrodynamics, structure the bacterial communities in the Bohai Strait.
