Objective　To investigate the systemic stress responses of laparoscopic cholecystectomy(LC). Methods　Seventy patients with cholecystolithiasis were randomly divided into two groups: LC and open cholecystectomy(OC). Peripheral blood samples were obtained during the preoperative day and 1, 3, 5, 7 day after operation. Serum cytokines levels (TNF-α, IL-1β and IL-6) and C-reactive protein(CRP) were measured. Results　Changes of TNF-α and IL-1β before or after surgery in both groups showed no significant difference(P>0.05). Serum concentrations of IL-6 and CRP after surgery in both groups were significantly higher than those before surgery(P<0.05); but there were no significant difference between the two groups(P>0.05). Conclusions　The systemic stress responses of LC have no significant difference comparing with OC.

Objective To evaluate the influence of respiration on the radiation dose distribution within target volume in radiotherapy with film dosimetry. Methods Radiation of 50 MU was delivered by a square, round, ellipse, dumb bell, or female shaped filed to the films within a moving or motionless Respiration Motion Phantom respectively, the dose distributions for the two motion status were measured and compared. In order to further verify the impact of respiration, a plank phantom was used on different shifting value: 0, 0.5, 1.0, 1.5 and 2.0 cm, respectively. A square, round, or eUipse-shaped filed was used for irradiation and the distributions in different status were measured and compared with film dosimetry. Iso-dose line comparison, NAT(Normalized Agreement Tests) and γ comparison were used for the comparison of dose distributions. Fs can be an index to reflect the variability of the areas that surrounded by iso-dose lines. (FS90, FS50, FS25 delegates the ratio of the areas that surrounded by 90 %,50 %,25 % iso-dose hne in different situation respectively). Results (1) Compared with motionless situation, the FS90 in horizontal movement situation became small and the FS25 became large. As the displacement became larger, the FS90 became larger and the FS25 became smaller. FS in vertical movement situation, square and dumb bell fields changed while the others didn't have a change. (2)γ and NAT comparison: In the horizontal movement situation, compared with the static phantom, Pγ < 60 % and PNAT < 75 %. Under vertical movement situation, Pγ were less than 85 % for the square, round, dumb bell and female shaped fileds. In the plank phantom verification, Pγ and PNAT became smaller as the movement became larger. Conclusions The respiration can impact on the dose distribution within the target volume in radiotherapy, leading to a smaller area of higher dose level and an expanded area of lower dose level. The influence will become more significant with larger movement of the target.

Objective To investigate whether B-cell activating factor (BAFF) involved in the patho-genesis of lupus nephritis (LN) by regulating phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling. Methods Twenty-eight lupus nephritis patients and 20 controls were included in this study. The clinical data were collected. BAFF levels in plasma were measured by ELISA, and the relationship between systemic lupus erythematosus disease activity index (SLEDAI) and BAFF were analyzed. The mRNA and protein levels of BAFF, phosphorylated-PI3K (p-PI3K), phosphorylated-Akt (p-Akt), phosphorylated-mTOR (p-mTOR) and Bcl-2 in kidney tissues were measured using real-time polymerase chain reaction (RT-PCR) and Western blotting. Data were analyzed using Mann-Whitney U test and Spearman correlation analysis. Results ①Plasma BAFF levels were significantly higher in LN patients [(580 ±45) ng/L] compared with controls [(208 ±30) ng/L](Z=-5.856, P<0.01), and significant positive correlation was found between plasma BAFF levels with SLEDAI (r=0.723, P<0.01). ② Plasma BAFF level in LN patients was positively correlated with 24 h UP and anti-dsDNA titers (r=0.381, 0.461, P<0.05). The protein level of BAFF in kidney tissues was positively correlated with 24 h UP and anti-dsDNA titer (r=0.469, 0.489, P<0.05).③The mRNA levels of BAFF, p-PI3K, p-Akt, p-mTOR and Bcl-2 in kidney tissues were increased in patients compared to controls[5.8±1.8 vs 2.1±0.7, Z=-4.915, P<0.01;6.7±0.9 vs 1.71±0.53, Z=-5.857, P<0.01;5.6±0.9 vs 1.8 ±0.5, Z=-5.751, P<0.01; 5.6 ±1.4 vs 1.6 ±0.4, Z=-5.291, P<0.01; 2.11 ±0.36 vs 1.33 ±0.22, Z=-4.844, P<0.01].④The protein levels of BAFF, p-PI3K, p-Akt, p-mTOR and Bcl-2 in kidney tissues were increased in patients compared to controls [0.72±0.19 vs 0.31±0.05, Z=-4.747, P<0.01;0.73±0.11 vs 0.33±0.09, Z=-5.834, P<0.01;0.77±0.06 vs 0.22±0.07, Z=-5.855, P<0.01;1.18±0.27 vs 0.47±0.13, Z=-5.416, P<0.01;2.08±0.37 vs 1.32±0.18, Z=-4.998, P<0.01]. Conclusion The findings of this study indicate that BAFF may participate in the pathogenesis of LN by regulating PI3K/Akt/mTOR signaling.

Purpose To study the clinic-pathological features, differential diagnosis and prognosis of extragastrointestinal stromal tumor ( EGIST) arising in the vulva and the rectovaginal septum. Methods Clinical manifestations, pathological features, immunohisto-chemistry, gene mutations, treatment and prognosis were analyzed in 1 case of EGIST arising in the vulva and 2 cases of EGIST arising in the rectovaginal septum with review of related literature. Results Case 1 was a 59-years-old woman who was found to have a 4. 4 cm × 3 cm × 3 cm recurrent mass in the right vulva after 6 months of the first resection. Case 2 was a 58-years-old woman who presen-ted with a 7. 3 cm × 6. 1 cm × 4. 6 cm mass in the rectovaginal septum. Case 3 was a 41-year-old woman who presented with an 8. 6 cm × 7. 4 cm × 6. 7 cm mass in the rectovaginal septum. Histologically, the uniform spindle cells showed the interlacing fascicular, whirl-pool and palisade patterns with high cellular density. Mitotic figures were readily identified. Immunohistochemical evaluation revealed that the tumor cells exhibited strong and diffuse staining for CD117, CD34, NES, H-Caldesmon and DOG-1. Molecular analysis showed the gene mutation of c-Kit exon 11 in all 3 cases. Conclusion EGIST should be considered in the differential diagnosis of the mesenchymal tumors arising in the vulva and the rectovaginal septum. The immunohistochemical evaluation and molecular genetic tes-ting are crucial tools for the differential diagnosis and assessment of the prognosis and targeted therapy of EGIST.
