ABSTRACT

Inguinal incarcerated hernia in adults is a common acute abdomen in hernia and abdominal wall surgery. If not treated in time, it is easy to progress to constrictive hernia, lead to intestinal ischemic necrosis, cellulitis of tegmental tissue outside the hernia, hernia sac empyema, intestinal fistula, and even cause toxic shock, with significantly increased mortality. The types of incarceration are different and the corresponding management methods are different. Based on the proposal of the concept of musculopubic foramen hernia repair, inguinal incarcerated hernia includes incarcerated indirect hernia, incarcerated direct hernia, incarcerated femoral hernia, etc. At present, there is no uniform standard for the comprehensive treatment of different types of inguinal incarcerated hernia, and the clinical management strategies of adult inguinal incarcerated hernia still face serious challenges.

ABSTRACT

In recent years, heavy ion beams have received great attention in the field of malignant tumor radiotherapy due to their radiation physics and biological characteristics. The high rate of local tumor control is one of its advantages, but the control rate of metastatic lesions is still crucial in the treatment of most malignant tumors. Clinical studies on the combined conventional radiotherapy and immunotherapy suggest that the combination of the two can not only control the primary lesions, but may also reduce or completely eliminate distant metastatic lesions. High linear energy transfer radiation, especially heavy ion beams, may have stronger potential in combined immunotherapy. Therefore, this article focuses on the basic research progress of heavy ion beams regulating anti-tumor immune effects and their combined application with immunotherapy.

ABSTRACT

Objective To explore the high-risk factors of metabolic bone disease (MBD) in premature infants by retrospective analysis of the clinical data so as to provide evidence for optimal clinical management. Methods Clinical data of premature infants with birth weight<1500 g admitted in our hospital from January 2016 to December 2017 were retrospectively analyzed. Infants with serum alkaline phosphatase ( ALP )>500 IU/L and blood phosphorus <1. 5 mmol/L were selected as MBD group and premature infants with birth weight <1500 g were selected randomly as non-MBD group. General data, pulmonary surfactant, continuous positive airway pressure, mechanical ventilation, start time of enteral nutrition, parenteral nutrition ( PN) time, breast feeding time and breast milk fortifier adding, drug usage, hospitalization time and complications were re-corded and compared between the two groups. Results A total of 440 premature infants with birth weight<1500 g were admitted to the hospital during the study period. 58 [ 13. 2% ( 58/440) ] infants were enrolled in the MBD group, among which infants with birth weight<1000 g accounting for 56. 9% ( 33/58) . High birth weight (OR=0. 62, 95% CI:0. 389-0. 990) was an independent protective factor of MBD in premature in-fants. The higher the birth weight, the lower the risk of MBD in premature infants. The longer duration of breast feeding time ( OR= 2. 191, 95% CI:1. 628-2. 950) , later initial time of enteral feeding ( OR=2. 695, 95%CI:1. 710-4. 248), longer duration of PN (OR=6. 205, 95% CI:3. 359-11. 463) time, longer duration of respiratory supporting time ( OR=1. 046, 95% CI:1. 026-. 067) , longer hospital stay time ( OR=1. 703, 95% CI:1. 109-2. 615) and small for gestational age ( OR=2. 965, 95% CI:1. 163-5. 658) were inde-pendent risk factors of MBD in premature infants. The duration of PN was the most important independent risk factor of MBD in premature infants (OR=6.205, 95% CI: 3.359-11.463). Conclusion Multiple factors can lead to MBD of premature infants. The high birth weight is an independent protective factor of MBD and the duration of PN is the most important independent risk factor of MBD in premature infants.

ABSTRACT

Objective To observe the changes in cytoskeleton (CSK) and glycosaminoglycan (GAG) synthesis following passage culture of articular chondrocytes and the correlation between CSK and GAG.Methods Eight male New Zealand White rabbits (8-month-old) were sacrificed by air embolism.After the chondrocytes from their knee joints were isolated by enzymolysis method,monolayer culture was performed.The chondrocytes of primary passage (P0) and passages 1 & 2 (P1,P2) were inoculated into 24-well plates with round cover slips put at the bottoms.Cell climbing slices were fixed after attachment of chondrocytes.The CSK proteins,actin,vimentin,tubulin and vinculin were stained by immuuofluorescence antibody on P0,P1 and P2 cell climbing slices,respectively.The CSK morphology was observed by laser confocal scanning microscopy and the fluorescence intensities of CSK proteins were detected by the fluorescence intensity software.The medium was changed for each generation after cell fusion and the GAG concentrations in the supernatants were measured at 24,36,48,60 h after medium change by alcian blue method.Results The intermediate filament networks became loosen and the dense distributions surrounding the nucleus decreased;more microtubule processes formed at the cell periphery with passage.The fluorescence intensity of actin of P1 chondrocytes was significantly increased than that of P0 (P < 0.05),but there were no such significant differences between P0 and P2 or between P1 and P2 (P > 0.05).The fluorescence intensities of vimentin and tubulin were significantly decreased with passage respectively,and there were such significant differences between any two of P0,P1 and P2 (P < 0.05).The GAG concentrations in the supernatants were significantly decreased with passage at each time point,and there were such significant differences between any two of P0,P1 and P2 (P < 0.05).Conclusions Passage culture of articular chondrocytes may lead to changes in morphology and protein expression intensity of the main components of CSK,and accordingly to decreased synthesis amount of GAG,one of the extracellular matrix of chondrocytes,indicating the changed characteristics of chondrocytes after passage and a certain correlation between CSK and GAG.

ABSTRACT

Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood.Radiation therapy has been integrated into the primary treatment of most patients with rhabdomyosarcoma, but which in turn potentially induces severe acute and late toxicities.Proton therapy in recent years has been more and more used in the treatment of rhabdomyosarcoma, which is safe and effective, with no serious adverse events.Compared with conventional photon therapy, proton therapy has distinct physical advantages and enables greater precision in the delivery of tumoricidal radiation doses with reduced irradiation of normal tissues, and improves quality of life for patients.Additional follow-up and prospectively studies are needed to determine whether proton therapy truly reduces the incidence and severity of late effects in comparison to patients treated with modern photon techniques.

ABSTRACT

BACKGROUND: Percutaneous vertebroplasty (PVP) is usually used for osteoporotic thoracolumbar fractures,which has various advantages such as easy to operate, short operation time, less trauma, rapid recovery,analgesic effect and so on. But its application is restricted due to nerve compression symptoms and pulmonary embolism caused by bone cement leakage. Thereafter, how to reduce the leakage of bone cement is an issue of concern.OBJECTIVE: To investigate the relationship between the lumbar quantitative computed tomography (QCT) values and contrast agent dispersion in osteoporotic thoracolumbar fractures. METHODS: Sixty cases of osteoporotic thoracolumbar fractures undergoing PVP were enrolled, and received QCT examination before surgery, and contrast agent was injected intraoperatively. X-ray examination was conducted to detect the bone mineral density, contrast agent dispersion and leakage of bone cement, and the relationship between the lumbar QCT values and contrast agent dispersion as well as leakage of bone cement.RESULTS AND CONCLUSION: (1) There were 110 vertebral fractures, and 74 vertebrae with contrast agent diffusing more than vertebral midline, accounting for 67.3%. There was significant difference in the contrast agent dispersion among groups (P 0.05). (3) These results suggest that contrast agent dispersion in osteoporotic thoracolumbar fractures has a certain relationship with the lumbar QCT values, and lumbar QCT values with more contrast agent dispersion, but the lumbar QCT values have no correlation with bone cement leakage. Therefore, choosing a appropriate approach based on the QCT values and contrast agent dispersion can reduce leakage and improve the safety of PVP.

ABSTRACT

Metastasis is the leading cause of death in breast cancer patients. However, the mechanisms underlying metastasis are not well understood and there is no effective treatment in the clinic. Here, we demonstrate that in MMTV-PyMT, a highly malignant spontaneous breast tumor model, IL-25 (also called IL-17E) was expressed by tumor-infiltrating CD4 T cells and macrophages. An IL-25 neutralization antibody, while not affecting primary tumor growth, substantially reduced lung metastasis. Inhibition of IL-25 resulted in decreased type 2 T cells and macrophages in the primary tumor microenvironments, both reported to enhance breast tumor invasion and subsequent metastasis to the lung. Taken together, our data suggest IL-25 blockade as a novel treatment for metastatic breast tumor.

ABSTRACT

Objective To investigate the impact of clinical factors on survival in patients receiving concurrent chemotherapy and three?dimensional radiotherapy ( 3DRT) for stage IV non?small cell lung cancer ( NSCLC) . Methods A total of 203 patients were enrolled in a prospective clincial study from 2008 to 2012, and among these patients, 178 patients were eligible for analysis of clinical factors. All patients were treated with platinum?based doublets chemotherapy, with a median number of chemotherapy cycles of 4( 2?6 cycles) and a median dose of 3DRT of 60?3 Gy (36?0?76?5 Gy).The Kaplan?Meier method was used to calculate overall survival ( OS) rates, the log?rank test was used to compare survival rates between groups, and the Cox regression model were used for multivariate analysis. Results The 1?, 2?, and 3?year overall survival rates were 56%, 16%, and 10%, respectively, and the median survival time was 13 months (95% CI=11?500?14?500). The univariate analysis showed that platelet count ≤221×109/L, neutrophil count ≤5.2×109/L, white blood cell count<7×109/L, and improvement in Karnofsky Performance Scale ( KPS) after treatment significantly prolonged OS ( P=0?000,0?022,0?003, and 0?029) , and metastasis to a single organ and hemoglobin≥120 g/L tended to prolong OS (P=0?058 and 0?075). The multivariate analysis showed that white blood cell count<7×109/L, platelet count ≤221×109/L, and improvement in KPS after treatment were beneficial to OS ( all P<0?05) . Conclusions White blood cell count and platelet count before treatment and KPS after treatment are prognostic factors for patients with stage IV NSCLC receiving concurrent chemotherapy and 3DRT.

ABSTRACT

This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups randomly, treated with normal saline, UEMAM, heavy ion beam radiotherapy and UEMAM plus heavy ion beam radiotherapy, respectively. The body weights, abdomen circumference of the mice were measured and the mouse behavior was monitored every day; survival time was recorded to evaluate life extension effect; flow cytometry technique was used to detect H22 cell apoptosis and cell cycle; protein levels of p53, Bax, Bcl-2 and cleaved Caspase-3 were analyzed by Western blot; the single cell gel electrophoresis was used to detect the level of deoxyribonucleic acid damage (DNA damage). The results suggest that UEMAM significantly increased survival time, and decreased body weights and abdomen circumference over the saline control group. The treatment increased cell apoptosis, cycle arrest and DNA damage compared to the saline control group. UEMAM significantly enhanced the therapeutic effect of heavy ion beam radiation in survival time, and decreased body weights and abdomen circumference in the tumor-baring mice. The combination increased cell apoptosis, cycle arrest and DNA damage compared to the radiotherapy group. The results of Western blot suggest that the treatment significantly enhanced p53-induced apoptotic signals. The experiment discovered that UEMAM could improve radiosensitivity of H22 ascitic tumor through activation of p53-mediated apoptotic signal pathway.

ABSTRACT

Objective To investigate the efficacy and safety of three?dimensional radiotherapy (3DRT) with concurrent chemotherapy for stage IV non?small?cell lung cancer ( NSCLC). Methods A total of 198 eligible patients from 2008 to 2012 were enrolled as subjects. With an age ranging between 18 and 80 years and a Karnofsky Performance Status ( KPS) score of 70 or more, those patients had no contraindication for radiotherapy and chemotherapy, and were newly diagnosed with stage IV NSCLC confirmed by histology or cytology, as well as limited metastatic disease (≤3 organs). Survival rates and acute toxicities in those patients were evaluated. Results The 3?year follow?up rate was 98?? 5% and the 3?year sample size was 165. The median overall survival (OS) and progression?free survival (PFS) were 13?? 0 months (95% CI,11?? 7 ?14?? 3 months) and 9?? 0 months (95% CI,7?? 7 ?10?? 3 months), respectively, while the 1?, 2?, and 3?year OS rates were 53?? 5%, 15?? 8%, and 9?? 2%, respectively. Multivariate analysis showed that a primary tumor volume smaller than 134 cm3 , a stable or increased KPS score after treatment, and a radiation dose of 63 Gy or more were independent prognostic factors for longer survival time ( P=0?? 008;P= 0?? 010;P= 0?? 014). The incidence rates of grade 3?4 neutropenia, thrombocytopenia, anemia, grade 3 radiation esophagitis, and grade 3 radiation pneumonitis were 37?? 9%, 10?? 1%, 6?? 9%, 2?? 5%, and 6?? 6%, respectively. The main cause of death was distant metastasis, and only 10% of the patients died of recurrence alone. Conclusions 3DRT with concurrent chemotherapy achieves satisfactory treatment outcomes with tolerable toxicities for stage IV NSCLC. Primary tumor volume, change in the KPS score after treatment, and radiation dose are independent prognostic factors for OS.Clinical Trial Registry Chinese Clinical Reistry,registration number:ChiCTRC10001026.
