Objective To analyze effects of target-oriented liquid therapy on postoperative complications in elderly hypertensive patients with radical gastrectomy.Methods 156 elderly patients with hypertension who underwent radical gastrectomy in our hospital from January 2014 to December 2015 were divided into the conventional group and the target group according to a random number table.Routine infusion was given to the patients in the conventional group,while the patients in the target group were treated with intraoperative target oriented liquid therapy.Intraoperative liquid intake and output volume,hospital stay,vasoactive drug use rate and the incidence of complications within 1 month after surgery were compared between the two groups.Results Target group versus conventional group showed that the colloid volume was(832.3 ± 216.6) ml vs.(1 031.3±245.8) ml,the amount of crystals was(1 157.6±149.2) ml vs.(1 559.8±201.4) ml,the total fluid replenishment was(1 940.2 ± 328.9) ml vs.(2 650.0 ± 276.6) ml,the hospitalization time was (9.8 ± 1.1) d and (12.5 ± 2.0) d (t =-5.607,-13.771,-18.021 and-10.447,respectively,all P=0.000).The use rate of vasoactive drugs was higher in the conventional group[69.2％ (54/ 78)] than in the target group [29.5 ％ (23 / 78)] (x2 =24.645,P =0.000).The complications within 1 months after surgery was higher in the conventional group[12.8％ (10/78)]than in the target group[3.8％ (3/78)] (x2=4.112,P=0.043).Conclusions Target-oriented liquid therapy can improve the prognosis of elderly patients receiving radical gastrectomy,reduce the incidence of postoperative complications and promote the early rehabilitation.

Objective To investigate the polyploid induction and identification of Nerviliae fordii for harvesting the polyploid plants. Methods The materials and methods for polyploid induction of Nerviliae fordii were screened separately by comparing the induction rates of rhizomes and bulbs under natural conditions and tissue culture environment, and by comparing soaking method with agar method. The effects of colchicine concentration ( 200, 300, 400, 300 mg/L), colchicine action time ( 7, 14, 21, 28 d), DMSO concentration ( 0, 10, 20, 40 mL/L) and KT concentration ( 0, 1.0, 2.0, 4.0 mg/L) on induction rate were observed by orthogonal design method. The polyploid induction in the treated plants was identified by morphology, cytology and chromosome methods. Results After the tissue culture rhizomes were treated with 300 mg/L colchicine, 10 mL/L DMSO, and 2.0 mg/L KT by agar method for 28 days, the polyploid induction rate arrived to 50%, showing better induction effect. The morphology of polyploid plants was characterized by giantism, and the leaf length, leaf width and plant height were respectively 152.17%, 158.67%and 60.90%of those of the diploid plants. The length, width and density of stoma of leaf epidermal cell as well as the number of chloroplast in the treated plants were 138.46%, 153.00%, 59.09% and 109.09% of those of the untreated plants. The results of chromosome identification showed that the amount of the tetraploid ( about 40) was 2 times of the diploid chromosome ( about 20) in the treated plants, proving that the achieved Nerviliae fordii was a tetraploid plant. Conclusion Polyploid plants of Nerviliae Fordii have been successfully obtained, which will supply evidence for improving species, richening seed-breeding resources, and selecting of improved seeds of Nerviliae fordii.

Objective To assessed the distribution of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in Xinjiang Uygur and Han nationality populations,and to investigate correlation and the incidence of all cases of macrovascular disease (coronary artery disease,carotid atherosclerosis and peripheral arterial disease)and analysis of risk factors.To further study the correlation between the incidence of two single nucleotide polymorphism (SNP)loci (rs2383206.rs10757278)on chromosome 9p21 in type 2 diabetes melli-tus(T2DM)of Han and Uygur ethnic and the incidence of all cases vascular disease,then to analysis the risk factors. Methods 497 adults with T2DM who were treated in the Endocrinology department in hospital from May 2012 to April 2014 were involved in this study,including 298 Uygur patients and 199 Han patients.215 non -T2DMpatients who were treated in the Cardiology department in hospital were also involved in the study,including 93 Uighur patients and 122 Han patients.Then the total 712 patients were detectedby using PCR -SNP Stream technology to analyse rs2383206.rs10757278 loci SNP genotyping.The relevant results were compared with t test,two different genotype distribution and allele frequency were compared with χ2 test,multiple factors analysis were calculated by Logisitic regression.Results The distribution of genotype with two SNP loci had no significant difference between the patients in Uygur group and Han group (rs2383206χ2 =5.570,P =0.062;rs10757278 χ2 =2.721,P =0.257 ),and there's no significant difference between the patients with macrovascular disease and non -macrovascular disease in all patients(rs2383206χ2 =0.120,P =0.950;rs10757278 χ2 =1.027,P =0.598).Logisitic regression analysis showed that the incidence of macrovascular was significantly associated with increasing age(χ2 =28.820,P =0.000)and fatty liver(χ2 =5.210,P =0.020)in Uighur group with type 2 DM.In Han group with type 2 DM,the macrovascular was significantly associated with the increase of age (χ2 =19.980,P =0.000),elevated fasting blood glucose (FPG)(χ2 =4.070,P =0.044)and poor controlled with glycosylated hemoglobin (χ2 =4.280,P =0.040). Conclusion This study found that there's no correlation between two single nucleotide polymorphisms (SNPS)loci (rs2383206.rs10757278)on chromosome 9 p21 large with macrovascular in Uygur group and Han group.Increasing age,higher FPG and poor controlled with glycosylated hemoglobin combined with fatty liver were the risk factors for macrovascular.

Objective To investigate the value of Habib 4X in hepatic resection. Methods The clinical outcome of 21 patients with liver disease who received liver resection at the Tianjin Third Central Hospital from November 2009 to April 2010 were retrospectively evaluated. All the operations were carried out by using Habib 4X. Results All patients received hepatectomy, including right hepatectomy in three patients, left hepatectomy in one patient, multiple segmentectomy in nine patients, single segmentectomy in seven patients and partial liver resection in one patient. All tumors were reseeted completely. The mean operation time was (50±25) minutes and the mean blood loss was(129±117)ml. No patient was transferred to ICU. Three patients were complicated with bile leakage, one with lymphatic leakage and four with pleural effusion, and they were cured by non-surgical treatment. There were no patients with postoperative hemorrhage, incision infection or hepatic failure. No mortality was observed. The mean postoperative hospital stay was(19±14)days. Conclusions Radiofrequency energy was applied along the margins of the tumor to create zones of necrosis before resection with a scalpel, offering hepatobiliary surgeons an additional method for performing liver resections with minimal blood loss, low morbidity and mortality rates. As for malignant tumors, minor or major liver resection assisted by Habib 4X is safe, and it can reduce the chance of positive incisal margin.

Platypnea orthodeoxia syndrome is associated with dyspnea and arterial oxygen desaturation accentuated by an upright posture. It can be secondary to an intracardiac shunt. We report a case of platypnea-orthodeoxia syndrome (POS) in a 58-year old male patient who had a pre-existing patent foramen ovale (PFO) and substantial pulmonary pathologies. He was successfully treated by percutaneous transcatheter closure of the PFO. Our case highlights the importance of recognition of this rare syndrome in patients who present with unexplained hy-poxia for whom transcatheter closure of the interatrial shunt can be safely carried out.

Aim To investigate the effects and possible mechanisms of kaemperol in the rats with chronic cere-bral ischemia.Methods Chronic cerebral hypoperfu-sion model was produced by permanent occlusion of bi-lateral common carotid arteries (2VO)in rats.After KAE treatment,the rats underwent Morris water maze and prehensile traction test.Neuronal morphology was observed using Nissl and HE staining.The activity of SOD and the content of MDA in brain tissue were de-termined.The DJ-1 protein expression was assayed by Western blot.Results Compared with 2VO model group,KAE significantly improved learning and memo-ry and the grasping ability.In addition,KAE signifi-cantly reduced brain tissue pathological injury induced by 2VO. Furthermore, KAE significantly increased SOD activity and enhanced antioxidant protein DJ-1 ex-pression in brain tissue.Conclusions KAE could sig-nificantly attenuate the cognitive impairment,limb bal-ance dysfunction and pathological injury in rats with chronic cerebral ischemia.The mechanism may be re-lated to improving the antioxidant system in vivo.

OBJECTIVETo evaluate in vitro effect of abnormal savda munziq (ASMq) on the proliferation and apoptosis of human hypertrophic scar fibroblasts (HSFs).

METHODSHSFs were divided into six groups to receive different treatments as group A (blank control group), group B-E (ASMq in different concentration), and group F(5-Fu). Each group contains six specimens. The HSFs were cultured in vitro. After culture for 48 hours, the CCK8 test and flow cytometry methods were used to detect the proliferation, cell cycle and apoptosis.

RESULTSThe proliferation of HSFs in the B, C, D and E groups was inhibited at G2/M period, while it was inhibited at G0/S period in group F (P < 0.05). The inhibition effect of ASMq (0.1-1.0 mg/ml) on the fibroblasts enhanced in a concentration-dependent manner. Flow cytometry analysis with annexin V-FITC and PI staining confirmed the apoptotic. When HSFs were exposed to ASMq at 1.0 mg/ml (group E) for 48 h, the percentage of apoptotic cells increased to (43.7 +/- 2.58)%, which was significantly higher than that of blank control group (2.2 +/- 0.59)%. The induced apoptosis effect was also increased in a concentration-dependent manner.

CONCLUSIONASMq has a inhibitory effect on the proliferation and an enhancement effect on the apoptosis of fibroblast. ASMq could be used as an effective drug for treatment of hypertrophic scar.
