Objective:To explore the efficacy of different unipolar electrocoagulation power on pathological injury of porcine kidney suffering suture-free partial nephrectomy (SFPN).Methods:From April 2018 to July 2018, nine Guizhou pigs were selected, with an average age of 3 years and an average weight of 48 kg. According to different hemostatic power of unipolar electrocoagulation during open partial nephrectomy, they were divided into three groups(60W group, 80W group, and 100W group), with 3 in each group. The left kidney was exposed with a surgical incision, parallel to the lumbosacral muscle.The left renal artery was clamped and about 2 cm renal tissue was excised at the middle pole of the left kidney. 60W, 80W and 100W were used by unipolar electrocoagulation for hemostasis until no bleeding occurred after the artery clamp was released. The total ischemia time was controlled within 20 min. Temperature was measured by a multi-channel thermometer probe which was inserted into the healthy kidney tissue at a distance of 2 mm, 5 mm, and 10 mm away from the unipolar electrocoagulation hook, and the upper pole of the kidney far away from the operation area. The time of operation, the volume of renal bleeding, the time of hemostasis and the temperature were recorded. On the 7th day after operation, the left kidneys were taken and the pathological changes were observed by toluidine blue staining.Results:All operations were completed safely and successfully. The operation time in 60W group, 80W group, and 100W group was (41.2±5.5)min, (35.1±3.7)min, (31.3±2.2)min , respectively. There was no significant difference of operation time among those group ( P>0.05). The blood loss of renal was (35.3±4.1)ml, (21.4±4.7)ml, (15.3±4.1)ml, respectively. The blood loss in the 100W group and 80W group was less than that in the 60W group ( P<0.05). And the blood loss in the 100W group was less than that in the 80W group ( P<0.05). The hemostasis time was (15.2±1.9)min, (10.1±1.4)min, (6.4±0.8)min. The hemostasis time in the 100W and 80W groups was less than that in the 60W group ( P<0.05). And the hemostasis time in the 100W group was less than that in the 80W group ( P<0.05). At the place of 10 mm away from the electrocoagulation hook, the temperature in the three groups were (33.1±1.1)℃, (34.0±1.0)℃, (34.3±0.6)℃, which was not significantly different from that of the respective upper poles. And there was no significant difference between the three groups( P>0.05). At the place of 5 mm and 2 mm away from the electrocoagulation hook, the temperature in the 100W group (41.7±1.3)℃, (61.4±6.4)℃ and the 80W group (38.6±2.4)℃, (50.3±6.0)℃ was higher than that in the 60W group (36.9±4.1)℃, (42.0±4.7)℃, and the temperature in 100W group is higher than that in 80W group ( P<0.05). When the power was 60W, 80W or 100W, the temperature in the place 10 mm away from the electrocoagulation hook was less than that in the place 5 mm away from the electrocoagulation hook ( P<0.05), and the temperature of the place 5 mm away from the electrocoagulation hook was lower than that of the place 2 mm away from the electrocoagulation hook ( P<0.05). The total pathological injury depth of wounds in 60W, 80W, 100W group was (7 323±50)μm, (8 119±100)μm, (8 896±40)μm, respectively. The depth in 100W group and 80W group was deeper than that in 60W group ( P<0.05), and the depth in 100W group was deeper than that in 80W group ( P<0.05). Conclusions:In SFPN, the hemostatic effect of three different monopolar electrocoagulation output power is satisfactory. With the increase of power, the hemostasis speed is faster. However, the temperature of surrounding healthy renal tissue would be higher, and the total pathological injury depth would be deeper.

Objective To study the effects of selenium(Se) and protein on cardiac morphology and expression of cellular glutathione peroxidase(GPX1 ) and mitochondrial thioredoxin reductase(TR2) in rat myocardial tissue.MethodsSixty healthy weaning male Wistar rats were randomly divided into four groups by two factors two levels factorial design(n =15).Drinking water was divided into two levels of Se-deficient(0 mg/L) and Se-adequate (0.25 mg/L); diet was divided into two levels of protein-deficeient (10％ protein and 0.008 mg/kg Se) and protein-adequate(20％ protein and 0.015 - 0.026 mg/kg Se).The rats were killed after feeding for one year.Pathological changes in myocardial tissues were observed under light microscope.The expression of GPX1 and TR2 in rat myocardial tissue was detected by immunohistochemistry and Western blotting.Results Compared between groups,the difference of the rate of myocardial necrosis in rats was statistically significant(x2 =11.04,P ＜ 0.05),in which Se-deficient protein-deficient group [66.7％ (8/12) ] was significantly higher than Se-adequate proteinadequate group [ 7.1％ ( 1 / 14),x2 - 11.06,P ＜ 0.05 ].GPX 1 positive rates in Se-deficient protein-deficient group,Se-adequate protein-deficient group,Se-deficient protein-adequate group and Se-adequate protein-adequate group were 0(0/12),81.8％(9/11 ),10.0％(1/10) and 100.0％(14/14),respectively,in rat myocardial tissue determined by immunohistochemistry.Of which,Se-adequate protein-deficient group and Se-adequate protein-adequate group were significantly higher than Se-deficient protein-deficient group and Se-deficient protein-adequate group(x2 =12.88,8.14 and 35.89,32.60,all P ＜ 0.05).The positive expression rates of TR2 in rats myocardial tissue of the four groups were 0(0/12),81.8％(9/11),0(0/10) and 100.0％(14/14),respectively.Of which,Se-adequate proteindeficient group and Se-adequate protein-adequate group were significantly higher than Se-deficient protein-deficient group and Se-deficient protein-adequate group (x2 =28.67,18.25 and 35.89,32.60,all P ＜ 0.05).The four groups'results of the overall mean of the relatively value of protein expression of GPX1 in cardiac tissue by Western blotting were 0.87 ± 0.13,1.18 ± 0.13,0.95 ± 0.13 and 1.74 ± 0.23,respectively.Through analysis of variance of factorial design,the effects of Se and protein on protein expression of GPX1 in the heart were statistically significant(F=124.93,43.16,all P＜ 0.05).And there was interaction between them(F=24.10,P＜ 0.05).The four groups'results of the overall mean of the relatively value of protein expression of TR2 in cardiac tissue by Western blotting were 0.63 ± 0.19,0.97 ± 0.24,0.55 ± 0.08 and 1.03 ± 0.31,respectively.Through analysis of variance of factorial design,the effect of Se on expression of TR2 in the heart was statistically significant(F =36.97,P ＜ 0.05).Conclusions Adequate Se and protein diet can increase the levels of GPX1 and TR2 in the heart compared to deficient Se and protein diet,can enhance anti-oxidizing ability,protect the myocardial endothelial cells,reduce degree of myocardial injury,and the combined effects of both are better.

OBJECTIVETo investigate the role of FCGR3A gene in susceptibility to systemic lupus erythematosus (SLE) using family based studies.

METHODSA total of 119 patients from 95 nuclear families, with SLE according to the American College of Rheumatology 1997 criteria were recruited. In addition, 316 family members of these patients were also genotyped. A family-based association study was used to explore the association between gene polymorphism and SLE. The authors studied the single nucleotide polymorphisms (SNP) encoding non-synonymous substitution in the cFCGR3A gene with respect to genetic susceptibility to SLE. The FCGR3A gene was genotyped with RFLP.

RESULTSAmong 119 SLE patients, the frequency of FCGR3A-72R/S, R and S allele were 39.4% and 60.6%; the frequency of FCGR3A R/S RR, RS and SS genotypes were 9.1%, 60.6% and 30.3%, respectively. Univariate (single marker) family-based association tests (FBATs) demonstrated that variant allele at the SNP(rs403016) in exon 3 of FCGR3A gene was significantly associated with genetic susceptibility to SLE in Additive Model(Z=2.544, P =0.01097) and Recessive Model(Z = 2.198, P = 0.02795). TDT analysis showed an excess of the allele of R from heterozygous parents to affected offspring (chi square was 9.30, P=0.0032).

CONCLUSIONThe findings suggest that the FCGR3A gene may be the susceptible gene of SLE in Chinese population, and that the individual carrying FCGR3A 72R allele was significantly associated with increase of susceptibility to SLE.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease, affecting about 0.6% of the Chinese population. Many patients are not well controlled by conventional treatments, thus there is need for new treatment regimens. In this study, we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis. METHODS: This study was a 52-week, multicentre, randomized, double-blind, placebo-controlled, parallel-group, Phase 3 trial. A sub-population of study participants (≥18 years) of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab, or placebo. The co-primary endpoints were psoriasis area severity index (PASI) 75 and Investigator's Global Assessment (IGA) 0/1 at Week 12. RESULTS: A total of 441 Chinese patients were enrolled in this study. Co-primary outcomes were achieved; 300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75 (97.7% and 87.2% vs. 3.7%, respectively; P < 0.001), and IGA 0/1 (82.3% and 69.7% vs. 2.7%; P < 0.001) at Week 12. Treatment efficacy was maintained until Week 52. There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period. CONCLUSION: Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis.
