Objective To evaluate the efficiency of primary hepatic carcinoma(PHC)using tran- scatheter arterial chemoembolization(TALE)combining with MSC.Methods Treatment group(30 patients with unresectable PHC)adopt MSC after TALE,while control group(10 patients with unresectable PHC)only adopt TALE,then observing the curative effect and survival rate.Results One year after treating,the local effect was 90 %,60 %,1～2 year survival rate was 90 %,30 % respectively,median life span was 15 months. Conclusion To treat PHC with TALE combining with MSC is an effective and non-invasive method.

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.

OBJECTIVETo investigate surgical outcomes of strip nail internal fixation with bone graft in treating tibial plateau fracture.

METHODSFrom May 2012 to May 2014,36 patients with tibial plateau fracture were retrospectively analyzed, including 25 males and 11 females with an average age of 43.5 (ranged from 17 to 65) years old. The time from injury to operation ranged from 3 to 10 days with an average of 5.8 days. All patients were treated with L-shaped and T-shaped strip nail internal fixation with bone graft. It was evaluated by the Knee Functional therapy assessment method of the Special Surgical Hospital of American at final following-up. Varus angle, caster angle and femorotibial angle were recorded and compared at 3 days and 1 year.

RESULTSOperative time was (2.2 ± 0.6) h on average, blood loss was (310.5 ± 36.2) ml on average, hospital stay was (14.8 ± 2.7) days on average. Thirty-six patients were followed up from 12 to 30 months with an average of 18.2 months. Fracture healing time ranged from 4 to 8 months with an average of 6.2 months. The difference is not significant among varus angle, caster angle and femorotibial angle at 3 days and 1 year. According to the knee functional therapy assessment method of the Specialized Surgical Hospital of American, 18 cases got excellent results, 13 good, 4 moderate and 1 poor.

CONCLUSIONStrip nail internal fixation with bone graft for the treatment of tibial plateau fracture could effectively prevent the joint surface from secondary collapse, and achieve anatomic reduction, stable fixation and earlier functional exercise in further to get satisfied clinical effects.

OBJECTIVETo investigate the mechanism of action of Chinese drug Langchuang-3 Granule (LC-3) in treating systemic lupus erythematosus (SLE) through observing its effects on body weight (BW), antinuclear antibody (ANA), spleen index and thymus index in BXSB SLE model mice, as well as the deposition of immune complex in mice' renal glomeruli.

METHODSSLE model mice were randomized into 4 groups: the control group (A), the LC-3 treated group (B), the Western drug treated group (C), and the LC-3 combined Western drug treated group (D). BW of mice was dynamically observed; spleen index (SI) and thymus index (TI) were measured by weighting method; serum anti-ANA level was detected by ELISA; IgG and complement C3 in renal glomeruli were analysed by direct immunofluorescence.

RESULTSBW of mice remarkably increased after treatment in Group B and D, showing a significant difference to that in Group A (P < 0.05). Lower TI level and higher SI level were found in the model mice. As compared with Group A, TI was higher in Group B and D, SI was lower in Group D, and both indices were lower in Group C (P < 0.05 or P < 0.01). Level of ANA decreased (converting from positive to negative) remarkably in all the three treated groups (P < 0.01). The fluorescence intensity of IgG and C3 in the renal tissue was weaker in Group B, C (both P < 0.05) and D (P < 0.01) than that in Group A.

CONCLUSIONBoth LC-3 and Western medicine showed remarkable effects in treating SLE model mice, and the combination of the two could display an effect better than that of using either alone.

ObjectiveTo study the impact of primary PCI in culprit artery on epicardial blood flow of nonculprit artery in patients with STEMI. MethodsEnrolled 117 patients with anterior wall STEMI were treated with primary PCI in the culprit artery, left anterior descending artery (LAD, as study group.Another 100 patients with normal coronary artery evidenced by angiography were enrolled as control group.The differences in CTFC (corrected TIMI frame count measured by using digital subtraction arteriography,TIMI =thrombolysis in myocardial infarction) and MBG (myocardium blood flow perfusion grading)between pre and post primary PCI in both culprit artery and nonculprit artery ( left circumflex artery, LCX),and CTFC and MBG were also detected in the subjects of control group. Blood samples were collected and the levels of CRP (C-reactive protein) were assayed. Clinical and angiographic features were analyzed.ResultsThe CTFC of nonculprit artery (LCX) and the level of MBG in patients with anterior wall STEMI were different from the level of MBG and CTFC in control group ( P＜0. 05) before primary PCI. The level of MBG and CTFC in nonculprit artery (LCX) were improved (P ＜ 0. 05 ) after primary PCI, but they did not resume to normal level. Patients without reflow in culprit artery had higher incidence of no reflow in nonculprit artery than patients with re-flow (78％ vs. 8％, P ＜ 0. 01 ), and the level of CRP in patients without reflow in nonculprit artery were higher than those in patients with re-flow ( P ＜ 0. 05). Conclusions The perfusion of nonculprit artery may be impaired in patients with STEMI. Although the perfusion of nonculprit artery may be improved after primary PCI in culprit artery, but it was still lower than those in the control group, and inflammation mechanism might contribute to it.

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.
