OBJECTIVETo investigate the impact of depression on clinical outcome of patients undergoing revascularization.

METHODSSelf-rating depression scale (SDS) assessment was made before and after coronary artery bypass grafting (CABG, n = 345) and percutaneous coronary intervention (PCI, n = 308) procedure. Patients were divided into depression and non-depression group. All patients were followed up for 12 months after procedure for the occurrence of rehospitalization and major adverse cardiovascular events (MACE) including all-cause mortality, nonfatal myocardial infarction or target lesion revascularization.

RESULTSDepression was present in 40.9% (n = 141) of patients after CABG, which was significantly higher than before procedure (24.3%, P < 0.01). The MACE rate was significantly higher in patients with post-procedure depression [8.5% (12/141)] than in patients without depression [2.9% (6/204), P < 0.05] and the incidences of target lesion revascularization and rehospitalization were also significantly higher in depression patients than in non-depression patients during the 12 months follow-up (all P < 0.05). Depression was present in 36.4% (n = 112) of patients after PCI, which was significantly higher than that before procedure (28.6%, P < 0.05). The MACE rate [8.0% (9/112) vs. 2.0% (4/196)] and rehospitalization rate [12.5% (14/112) vs. 4.6% (9/196)] were significantly higher in depression patients than in patients without depression during the 12 months follow-up (P < 0.05). There was no significant difference on SDS score between the PCI and CABG before the procedure. However, after the procedure, the SDS score for patients undergoing CABG was significantly higher than in patients undergoing PCI (48.9 ± 9.8 vs. 45.7 ± 10.5 P = 0.01). The level of serum IL-6 was significantly higher in depression patients than in patients without depression (P < 0.05).

CONCLUSIONPrevalence of depression is high in patients treated with revascularization procedures and is linked with poor post-procedure prognosis.

At present, the objective of cutting and pruning Cistanche deserticola is to harvest in successive years and enhance the harvesting yield and quality of C. deserticola in the process of the artificial cultivating C. deserticola. An experiment was conducted focusing on cutting and pruning C. deserticola in artificial forests of Haloxylon ammodendron drip-irrigated with saline water at the hinter-land of the Taklimakan desert, according to different growth stages and lengths. The results were following: (1) The effect of cutting on C. deserticola was similar to that of pruning, which resulted in three kinds of morphological types, not related to the bloom and size of C. deserticola. (2) The growth forms were diversified after pruning. Among them, there had sprouting new body, died or maintaining life with no sprouting, mildewed on its surface layer, etc. However, some of new bodies were sprouting from the lower part of the old body. The death rate of bloomed C. deserticola was higher than that of the underground, and the death rate of the 40 cm in stubble height for C. deserticola was higher than those with the stubble height of 20 cm and 5 cm. (3) Most of the diameter of living C. deserticola after pruning was increasing, but some of them changed little. (4) The mildew and rot of C. deserticola and the broken of the roots of the H. ammodendron and the fallen of the point of the inoculated when it was dug, which would cause the death of the C. deserticola. On the other, the yield-increasing effect and the economic benefit of the techniques of the pruning of Cistanche would need further research and evaluate. Therefore, the application of this technique needs to be cautious.

Objective To explore the expression level and influencing factors of CD4 +CD25 + regulatory cells(Treg)among male drug -abusers with syphilis.Methods 144 male drug -abusers with syphilis,41 male drug -abusers without syphilis,35 male non -drug abuser with syphilis and 35 male healthy volunteers were enrolled in this study.Expression levels of CD4 +CD25 +Treg of them were detected.A questionnaire interview was conducted among these participants, including drug abuse duration,drug types and abuse ways.Results The levels of Treg expression of drug -abusers with syphilis were significantly higher than that of drug -abusers without syphilis and non -drug abuser with syphilis (P <0.01 ).Despite of the stage of syphilis,types of drugs and abuse way,Treg expression levels with drug abuse duration of"above 1 -year"were significantly higher than those of "1 -year or below"(P <0.01 ).Treg expression levels were positively correlated to drug abuse duration (R2 =0.672,P <0.01)among patients.Among the participants,people both with traditional and new drugs were significantly higher than that with only traditional or new drug (P <0.01).In addition, people both with injecting and non -injecting abuse were significantly higher than that with one way of drug -abuse (P <0.01).Among those with drug abuse duration of "above 1 -year",Treg levels of drug -abusers with traditional drugs and injecting abuse way were remarkably higher than that with new drug and non -injecting abuse respectively (P <0.01). Conclusion Among male drug -abusers with syphilis,suppression of cellular immune function resulting from increased CD4 +CD25 +regulatory T cells is related to drug abuse duration,and is also influenced by drug types and abuse ways.

AIM To observe the curative effects of Modified Buzhong Yiqi Decoction (Codonopsis Radix,Astragali Radix,Atractylodis macrocephalae Rhizoma,ect.) on perioperative period of intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis type.METHODS One hundred and twenty cases of elderly intertrochanteric fractures were randomly divided into treatment group and control group,60 cases in each group.All patients underwent closed fracture reduction and proximal femoral nail anti-rotation (PFNA) fixation.During the perioperative period,the control group only received conventional treatment,while the treatment group received conventional treatment and Modified Buzhong Yiqi Decoction once a day.The levels of interleukin-6 (IL-6),interleukin-10 (IL-10) and tumor necrosis factor (TNF-α) of both groups in preoperative and in the 1st day,the 7th day,the 14th day of postoperative were observed and compared.The complications and the curative effects according to the Harris score also were observed and compared between the two groups.RESULTS In preoperative,there was no significant difference in levels of IL-6,IL-10 and TNF-α between the two groups (P ＞ 0.05).The levels of IL-6 and TNF-α in the 1 st day of postoperative in the control group were significantly higher than those in the treatment group (P ＜0.05,P ＜0.01).And the levels of IL-10 were similar between the two groups (P ＞0.05).In addition,in the 7th day and the 14th day of postoperative,the levels of IL-6,IL-10 and TNF-α in both groups were all decreased,moreover,the descent degree in treatment group was more significant than those in the control group (P ＜ 0.05,P ＜ 0.01).The treatment group had the lower incidence of complications and the higher curative effects than those in the control group,both differences were statistically significant (P ＜0.05).CONCLUSION Modified Buzhong Yiqi Decoction applying to the perioperative period of femoral intertrochanteric fractures in elderly patients with Qi deficiency and blood stasis,can effectively reduce the perioperative inflammatory response,reduce the incidence of postoperative complications,and improve the curative effects.So it has a positive effect on the rehabilitation for the traumatic patients and is worthy of clinical promotion.

Objective: To establish an echocardiography parameter scoring system for assessing the risk of 1 year re-admission in patients with left ventricular systolic dysfunction (LVSD). Methods: A total of 412 chronic LVSD patients treated in our hospital from 2007-01 to 2016-01 were studied and the end point event was 1 year re-admission. The data included in 280 patients from 2007-01 to 2014-12 for establishing the scoring system and 132 patients from 2015-01 to 2016-01 for verifying the system. Based on 7 echocardiography parameters, the patients were divided into 7 sets of groups: ① Left ventricular diameter (LVD): Group0, n=290 and Group1, n=122;② Mitrial regurgitation (MR): Group0, n=203, Group1, n=138 and Group2, n=71; ③ Tricuspid regurgitation (TR): Group0, n=302, Group1, n=90 and Group2, n=20; ④ LVEF: Group0, n=272 and Group1, n=140; ⑤ Pulmonary artery systolic pressure: Group0, n=282 and Group1, n=130; ⑥ Hydropericardium: Group0, n=347 and Group1, n=65; ⑦ Hydrothorax:Group 0, n=261, Group1, n=86 and Group2, n=65. The parameters were identified by COX regression analysis, weighted value of scoring system was calculate by hazard ratio (HR), predictive value for1 year re-admission was assess by ROC curve and finally, scoring integration was verified by validation data group. Results: The integration score was calculated as follows: LVD>60mm=1 point; TR: Group1=1 point and Group2=3 points; MR: Group1=2 points and Group2=4 points; Hydrothorax: Group1=2 points and Group2=3 points;Hydropericardium=1 point. COX regression analysis indicated that for 1 year re-admission: HR=1.552 in Group1 vs Group0, HR=3.374 in Group2 vs Group0 and HR=4.562 in Group3 vs Group0, all P<0.05. The AUC of ROC for establishing the data was 70.0% (95% CI 0.640-0.761) and for verifying the data was 70.4% (95% CI 0.616-0.792); the best integration score was 4 points. Conclusion: Echocardiography parameter scoring system may better predict the risk of 1 year re-admission in LVSD patients which is superior to single echocardiography parameter.

OBJECTIVETo evaluate the survival, complication and postoperative mortality after D(1) or D(2) lymph node dissection for gastric cancer.

METHODSAll the randomized clinical trials about nodal dissection for gastric cancer published within the last 20 years were collected. Quality assessment was done on each trial and relevant data were extracted from qualified trials. Meta-analysis was performed with the use of RevMan 4.2 (Cochrane) for statistic analysis.

RESULTSThree hundred and ninety-four trials were yielded at the initial search. Four trials, recruited 1316 cases of gastric cancer in total, were included after quality assessment. Results of Meta-analysis showed that standard D(2) dissection could effectively improve patients' long-term survival [RR 1.35, 95%CI(1.12-1.62), NNT=9] as compared with D(1) dissection. If splenectomy (or pancreatico-splenectomy) was involved, D(2) dissection only improved the clinical outcome of T(3)-staged cases [RR 1.80,95%CI(1.03-3.15), NNT=13]. D(2) dissection produced higher rates of postoperative complication [RR 1.72,95%CI(1.46-2.03), NNT=6] and mortality [RR 2.12,95%CI(1.39-3.25), NNT=21] than D(1) dissection.

CONCLUSIONSStandard D(2) dissection can increase the overall survival rate when compared with D(1) dissection. If splenectomy (or pancreatico-splenectomy) cases are involved,D(2) dissection can only improve the survival rate of T(3)-staged patients. D(2) dissection yields higher postoperative morbidity and mortality than D(1) dissection.

OBJECTIVETo investigate the safety of different level of tween 80 by comparing the degree of pseudoanaphylactoid reactions (PR) induced by medicinal tween 80 and injectable tween 80.

METHODThe analysis of vascular permeability of the mice ears: ICR mouse were divided into different test groups, the mice were intravenously injected with solutions of medicinal tween 80 and injectable tween 80 with 0.2%, 1% and 5% concentration, positive control Compound 48/80 and 5% glucose injection. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. The analysis of vascular permeability of the rat's skin: the rats were intravenous injected with 0. 6% Evans blue normal saline solution first, 10 minutes later, the same substances were intradermal administrated into the back of rats. The rats were sacrificed and the diameter of locus ceruleus and the content of Evans blue leak out were measured 20 min after injection.

RESULTMedicinal tween 80 and injectable tween 80 with 5% concentration caused obvious vascular hyper permeability in ICR mice, but the degree of vascular hyperpermeability caused by injectable tween 80 was lighter than by medicinal tween 80. Other tween 80 didn't cause obvious vascular hyper permeability in the ears of mouse. The solution of different concentration of tween 80 caused obvious locus ceruleus reaction in rat's back. As for the content Evans blue leak out, there was no statistical significance between each group except positive control Compound 48/80 group.

CONCLUSIONTween 80 can cause obvious vascular hyper permeability and the effect is dose dependent, which indicated that tween 80 can cause PR. On the other hand, injectable tween 80 is more security than medicinal tween 80, the dosage of tween 80 should be still controlled strictly so that to decrease the incidence of PR.
