Objective To investigate the clinical characteristics, location, treatment and prognosis of periosteal osteosarcoma. Methods The data of 1 patient with periosteal osteosarcoma was retrospectively analyzed, and the 35 cases reported in CNKI database in recent years were analyzed. Results The patient of periosteal osteosarcoma was female and 16 years old. Periosteal osteosarcoma occurred in the tibia. The patient was treated with extensional resection, and had no recurrence and metastasis 3 months after operation. Among the 35 patients reported in the literature, the age of onset ranged from 14 to 35, the female was slightly more than the male (19 cases vs. 16 cases), and the lesion site was mainly in the tibia and femur. The 35 patients underwent surgical treatment, and 4 cases had metastasis;6 cases were treated by surgery combined with chemotherapy. Conclusions Female patients with periosteal osteosarcoma were slightly more than male, and the lesion site is mainly in the tibia and femur. The chemotherapy effect is not exact, and extensional resection is the most effective treatment method. The transfer site and the characteristics are not exact.

Abstract: Objective　In order to explore the application prospects of the phenyl pyrazole insecticide fipronil for mosquito control and identify potential target genes involved in the resistance of Aedes aegypti to fipronil, and lay the foundation for an in-depth study of the resistance mechanism of Aedes aegypti to fipronil. Methods　Using Aedes aegypti sensitive strains as experimental materials, Aedes aegypti larvae were treated with fipronil, and the differences in gene expression of Aedes aegypti larvae before and after drug administration were compared at the transcriptome level using transcriptome sequencing combined with bioinformatics analysis, and the differential genes were analyzed. Results　A total of 757 differentially expressed genes were identified between the fipronil-treated group and control group, including 217 and 540 up- and down-regulated genes, respectively. Among these, the expression of glutamate-gated chloride channel (GluCls) genes varied significantly before and after treatment. Gene ontology analysis revealed that differentially expressed genes were enriched in catalytic activity, binding, metabolic processes, and membrane-related functions, while KEGG pathway analysis indicated enrichment in biosynthesis, metabolism, and life regulation processes, while the glutathione metabolic pathway was enriched in 15 differentially expressed genes. Conclusions The transcriptome results revealed that GST gene expression was significantly upregulated in fipronil-treated Aedes aegypti larvae, indicating that GST gene is involved in the development of fipronil resistance in Aedes aegypti larvae. In addition, GluCls gene expression was also significantly different before and after treatment, suggesting that GluCls migh be a potential target receptor for fipronil resistance in Aedes aegypti. As GluCls is an ideal target receptor found only in invertebrates, this discovery provides a reference and basis for further exploration of the toxicological mechanism of fipronil on Aedes aegypti.

OBJECTIVETo observe the protective effect of Panax Ginseng (PG), Aconitum Carmichaeli (AC), and their combination (PG-AC) on myocardial ischemia/reperfusion injury in rats.

METHODSRat's ischemia reperfusion injury model was established by ligating left anterior descending coronary artery for 60 min followed by reperfusion for 240 min. Forty male rats were randomly divided into five groups, the sham operation group, the model group, the three treated groups. The three treated groups were treated with PG, AC and PG-AC respectively by given the drugs 10 min before ischemia reperfusion, and to the sham operation group and the model group, saline was given instead. The infarction area, pathologic changes of myocardial tissue (under light and electron microscopy), activity of creatine phosphokinase (CK) and lactate dehydrogenase (LDH) in serum, content of malondialdehyde (MDA) and superoxide dismutase (SOD) in myocardial tissue were observed to evaluate the protective effect of treatment.

RESULTSThe area of acute myocardial infarction was lesser, activity of LDH and CK were lower in the three treated groups than those in the model group. Content of SOD was significantly higher and that of MDA was markedly lower in the former three than those in the model group. Light and electron microscopic examination showed that the necrotic degeneration and pathologic changes of myocardiocytes in the treated groups were significantly milder than that of the model group. As comparing the effect between the three treated groups, PG-AC showed the best, and insignificant difference was shown between PG and AC.

CONCLUSIONBoth PG and AC, and their combination have obviously protective effects on myocardium against ischemia reperfusion injury, which of PG-AC is superior to that of PG or AC used singly.

Objective:To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately,and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.

Objective To investigate the treatment outcome of patients with localized soft tissue sarcoma (STS) and related prognostic factors,with a focus of the role of postoperative radiotherapy in the treatment of STS.Methods A retrospective analysis was performed for the clinical data of 203 STS patients who underwent organ preservation surgery in Fudan University Shanghai Cancer Center from July 2000 to July 2010.Of all the patients,76(37.4％) received adjuvant radiotherapy,which was delivered via anterior-posterior parallel opposed fields at a dose of 45-70 Gy.The Kaplan-Meier method was used to calculate survival rates,the log-rank test was used for survival difference analysis,and the Cox proportional hazards model was used for multivariate analysis.Results The follow-up rate was 100％.The 5-year overall survival (OS) rate,local failure-free survival rate,and distant metastasis-free survival rate were 69.1％,69.2％,and 68.0％,respectively.The multivariate analysis showed that pathological subtype,tumor size,resection margin status,and postoperative radiotherapy were influencing factors for OS.Among these factors,postoperative radiotherapy was associated with a significantly reduced risk of local recurrence in STS patients (HR=0.327,95％ CI 0.177-0.605,P=0.000) and a significantly increased OS rate (HR=0.489,95％ CI 0.266-0.897,P=0.021).Conclusions Postoperative radiotherapy can reduce local recurrence and improve OS in patients with localized STS,and further studies are needed to clarify its role.
