2.Research progress in the operational techniques of laparoscopic partial nephrectomy
Chinese Journal of Clinical Oncology 2014;(9):601-603
Compared with open surgery, laparoscopic surgery (LS) provides distinct advantages. However, LS is limited because of the lack of flexibility and tactile feedback. These drawbacks may result in prolonged learning curve and increase in difficulty of sur-gery, particularly for reconstructive LS. This study aimed to determine more efficient methods and resolve several limitations, such as surgical education, LS, surgical procedures (suturing and knotting), iconography, and biotechnology in LS. This review provides a broad overview of studies related to this field.

AIM:To observe the effects of neuroglobin ( NGB) overexpression on the apoptosis induced by Aβin the brains of double transgenic AD ( APPswe/PS1dE9) mice and to explore its potential mechanisms .METHODS:Twenty-four 13-month-old double transgenic AD mice were randomly divided into 3 groups:intracerebroventricular injection with normal saline (NS) group, intracerebroventricular injection with pcDNA3.1 and NS group, and intracerebroventricular injection with pcDNA3.1 and pNGB group.Immunohistochemistry was used to detect the expression of Aβ1-42 in the brains. TUNEL staining was used for analyzing the apoptosis , and the protein levels of cleaved caspase-3, caspase-9, PI3K, Akt and p-Akt were determined by Western blot .RESULTS: After intracerebroventricular injection with pNGB , the areas of Aβ1-42 in the hippocampus and cortex were decreased compared with NS group and pcDNA 3.1+NS group (P<0.01).The TUNEL-positive staining cells in the pNGB group were less than those in NS group and pcDNA 3.1 group ( P<0.01 ) . NGB overexpression attenuated the protein levels of cleaved caspase-3 and caspase-9 (P<0.01), but induced the produc-tion of PI3K and p-Akt (P<0.01).CONCLUSION:Overexpression of pNGB significantly inhibits the generation of Aβand attenuates the apoptosis induced by Aβ, indicating that NGB overexpression activates PI 3K/Akt pathway and inhibits the production of cleaved caspase-3 and caspase-9, which were tightly related with apoptosis .

Objective To evaluate effects of three modalities with intravenous immrnoglobulin(IVIG) infusion in the treatment of Kawasaki disease(KD). Methods 76 KD cases were treated by the IVIG in the Deparment of Pediatric of Kaiping Central Hospital from 1998 to 2004.The three modalities were as follows: four days treatment(0.4 g/kg,for four days continuance),two days treatment(1 g/kg,for two days continuance),one day treatment(2 g/kg,for one day).Results(1) In treatment of fever,conjunctiva congest and mouth change,and recover in white blood cell and erythrocyte sedimentation,one day treatment and two days treatment had better curative effects with significantly difference(P0.05).(3)In the prevention of coronary artery dilate(CAD),one day treatment and two days treatment had better curative effects significantly difference(P

Background and purpose: miR-210 was closely related to the occurrence and development of gastric cancer, but its mechanism and clinical significance were still not clear. The purpose of this study was to explore the expression of miR-210 in gastric cancer tissues and its clinical significance. Methods: The expression of miR-210 was detected in gastric cancer tissues and the corresponding adjacent tissues. The relationship between the expression of miR-210 and clinical pathological factors and prognosis was analyzed. Results: Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) showed that the expression of miR-210 in gastric cancer was higher than that in adjacent tissues, and there was a significant difference between the two groups (P<0.05). The expression of miR-210 was closely related to tumor size, lymph node metastasis and TNM stage, but was not related to age, gender, tumor dif-ferentiation and depth of invasion. The 5-year survival rate of patients with low miR-210 expression was 48.2%, where-as the 5-year survival rate of patients with high miR-210 expression was 30.4% (χ2=4.216, P=0.040). Conclusion: The expression of miR-210 in gastric cancer was higher than that in adjacent tissues, and maybe related to the development and prognosis of gastric cancer. miR-210 is expected to be a new diagnostic marker and therapeutic target for gastric cancer.

Objective To observe the influence of wind-dispelling therapy on therapeutic effect of blood-cooling and kidney-tonifying herbs for chronic idiopathic thrombocytopenic purpura(CITP),and to investigate its immunoregulatory effect.Methods Forty-two CITP patients were randomized into 2 groups:the treatment group(N=22) received therapy of dispelling wind,cooling blood and tonifying kidney,and the control group(N=20) received therapy of cooling blood and tonifying kidney.Six weeks constituted one treatment course,and the treatment lasted 3 courses.Serum interleukin 2(IL-2),soluble IL-2 receptor(sIL-2R),Fas protein,Fas-L protein,and platelet-associated immunoglobulin G(PAIgG) levels and lymphocyte subtypes were compared before and after treatment.Results In the treatment group,14 patients were clinically cured,5 markedly effective,2 effective,1 ineffective and the total effective rate was 95.5%;in the control group,8 patients were clinically cured,4 markedly effective,3 effective,5 ineffective and the total effective rate was 75.0%.The therapeutic effect in the treatment group was superior to that in the control group(P

Objective To observe the effect of Wuyaojing granules(WYJG) on immunological function of mice.Methods Mice were randomly divided into six groups:the high-dosage WYJG group(6.0g/kg),the midst-dosage WYJG group (2.0g/kg),the low-dosage WYJG group(1.0g/kg),the Lindera aggregate group (0.9g/kg),the korean Ginseng group (2.0g/kg) and the normal control group(H2O).After a period of 30-day treatment,the effects of WYJG on the T lymphocyte transformations capacity induced by ConA,delayed hypersensitivity leaded by DNFB,the number of lymphocyte B,serum level of hemolysin and NK activity were observed. Results The high-dosage and the low-dosage WYJG could significantly increase T lymphocyte transformations capacity induced by ConA(P0.05).Conclusion WYJG can significantly increase T lymphocyte transformations capacity induced by ConA and strengthen delay hypersensitivity leaded by DNFB.

Objective:To assess the role of EGFR mutations on pemetrexed response in patients with advanced lung adenocarcino-ma. Method: Forty pulmonary adenocarcinoma patients with evaluable lesions were retrospectively screened .They had been treated with pemetrexed-included chemotherapy and had EGFR gene test results. The evaluation endpoints were overall response rate,disease control rate and progression free survival. Result:No significant statistical difference was seen in overall response rate(ORR) (44.4%VS 31.8%, respectively) and disease control rate(DCR) (88.9%VS 81.8%, respectively ) between EGFR wild group and EGFR muta-tion group, but patients in EGFR wild group had longer progression free survival(PFS) ( 8.9 months VS 5.3 months;P=0.046). Conclu-sion:EGFR mutation status can influence the efficacy of pemetrexed.
