Objective To investigate the effects of three procedures for hysterectomy.Methods The clinical characteristics of 370 cases who respectively received hysterectomy by total transabdominal hysterectomy(TAH,150 cases),transvaginal hysterectomy(TVH,120 cases),or laparoscopically assisted vaginal hysterectomy(LAVH,100 cases)were analyzed and their effects and outcomes and the expenses for medical treatment were compared from 2000 January to 2005 December.Results The average operation time of TAH,TVH and LAVH was(78?28) minutes,(102?35)minutes,(119?28)minutes respectively.The average operation time of TAH was significantly shorter than that of TVH and LAVH groups(P＜0.01).The volume of hemorrhage during operation in TAH group was less than that of other two groups significantly[TAH(53?29)ml,TVH(110?35)ml,LAVH(93?50 )ml](P＜0.01).The average time of bowel function recovery in TAH group[(42?7)hours]was significantly longer than that of TVH[(23?5)hours]or LAVH[(25?4) hours]groups(P＜0.01).The average hospital stay after opera- tion in TAH[(8.9?1.1)days]group was significantly longer than that of TVH[(5.7?2.4)days]or LAVH [(6.3?1.9)days] groups(P＜0.01).The average expenses for medical treatment in LAVH[(7273?938)yuans] group was significantly more than that of TAH[(5594?308)yuans]or TVH[(5450?167)yuans]groups(P＜0.01).But the lesion and the complication after operation of three groups had no difference.Conclusion Different procedures for total hysterectomy have their own advantage and disadvantage.The operation procedure must take ac- count of the economy,echnique of medical treatment and the condition of the hospital.

Objective To investigate insulin-like growth factor-1(IGF-1) on the protective effect of infant myocarditis.Methods The serum levels of IGF-1 was detected by two-site enzyme-linked immunosorbent assy ( ELISA) and CK-MB by electrochemiluminescence at the acute and convalescent in 50 infant with myocarditis,and 50 normal healthy children as the controls.Results The serum levels of IGF-1 in acute myocarditis was significantly lower than those of healthy children and the convalescen[(22.90 ±9.30) mg/L vs (45.69 ±10.95) mg/L, (38.99 ±9.06)mg/L,all P<0.01],while the CK-MB was significantly higher than those of the control group and the convalescent[(77.48 ±8.71)mg/L vs (14.99 ±7.62)mg/L,(17.99 ±6.31)mg/L,all P<0.01.IGF-1 and CK-MB was negative correlation (r=-0.62,P<0.01).Conclusion IGF-1 is involved in the repair process of myocardial injury in myocarditis infant,and play some protective role in the mechanism.

OBJECTIVETo study the differences in the toxicity of vinegar-processed Kansui Radix on normal and cancerous ascites model rats.

METHODNormal and cancerous ascites model rats were taken as the research objects and orally administered with different doses of vinegar-processed Kansui Radix for 7 d. Pathological sections were prepared to observe the damages in liver, stomach, intestinal tissues in rats and detect the impacts on serum, liver, stomach and intestinal tissues and the oxidative damage index.

RESULTCompared with the blank group, all of normal administration groups and model groups showed significant damages in liver, stomach and intestinal tissues. Compared with the model groups, all of normal administration groups revealed notable alleviation in damages. Compared with the blank group, the model groups showed significant increases in AST, ALT and MDA in serum and liver (P < 0.01) and a significant decrease in GSH in serum and liver, stomach, intestinal tissues (P < 0.01). Compared with the blank group, the results showed significant decreases in ALT, AST in serum and ALT in liver in model low, medium and high dose groups and AST activity in liver tissues in the normal high dose group (P < 0.05, P < 0.01); significant decreases in GSH in serum and stomach tissues in normal low, medium and high dose groups and GSH content in liver and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01); notable rises in MDA in liver tissues in normal low, medium and high dose groups and MDA content in serum and stomach and intestinal tissues in normal medium and high dose groups (P < 0.05, P < 0.01). Compared with model groups, data revealed significant decreases in ALT, AST in serum in model low, medium and high dose groups, AST in liver tissues of model medium and high dose groups and ALT activity in liver in the model high dose group (P < 0.05, P < 0.01); significant increases in GSH content in serum and stomach tissues of model low, medium and high dose groups, GSH in liver tissues in model medium and high dose groups and GSH in intestinal tissues in the high dose groups (P < 0.05, P < 0.01); and notable declines in MDA content in serum in model low, medium and high dose groups, MDA in liver tissues of model medium and high dose groups and MDA in stomach and intestinal tissues the high dose group (P < 0.05, P < 0.01).

CONCLUSIONAccording to the study, vinegar-processed Kansui Radix showed a significant lower toxicity liver, stomach, and intestines of cancerous ascites model rats, which provided a basis for clinical safe application of vinegar-processed Kansui Radix based on symptom-based prescription theory.

Objective To investigate the clinical effect of early rehabilitation treatment on patients with severe traumatic brain injury (sTBI).Methods Forty sTBI patients were divided into treatment group (n =20) and control group (n =20) according to the random number table.Conventional treatment was performed on all patients including dehydration to decrease intracranial pressure,hemorrhage control,neurotrophic treatment,antiinflammation therapy,and gastric acid control.In addition to these interventions,patients in treatment group received hyperbaric oxygen treatment,median nerve stimulation,fastigial nucleus stimulation,and bedside motor therapy in the early period.Intracranial pressure and partial pressure of brain tissue oxygen (PbtO2) were continuously monitored during the process of treatment.GCS was measured before and 15 days after treatment and single-photon emission computed tomography (SPE-CT) was used to evaluate cerebral perfusion.Results There was no statistical difference between the two groups with respect to GCS in advance of treatment (P ＞ 0.05),but GCS differed between treatment group and control group after treatment [(10.18 ± 3.75) points vs (8.33 ±2.36) points,P ＜0.05],with substantial improvement in treatment group.Significantly improved cerebral perfusion was seen in treatment group.On day 5 after treatment,intracranial pressure in treatment group lowered significantly compared with that in control group (P ＜ 0.05).On day 6 after treatment,PbtO2 was significantly higher in treatment group than in control group (P ＜ 0.05).Conclusion Early rehabilitation treatment leads to improved outcome and acts a positive effect on nerve function recovery.

Lipopeptides produced by Bacillus subtilis JA antagonized a broad spectrum of fungal pathogens. Crude lipopeptides were extracted with methanol from the precipitate which was obtained by adding 6 mol/L HCl to the cell-free culture broth.The crude extract was run on Diamonsil C_(18)column(5?m,250 mm?4.6 mm) in reverse phase HPLC system to purify the lipopeptides.Inhibitory ability and IC_(50)values of lipopeptides towards various microorganisms were determined by agar diffusion method.The results showed lipopeptides exhibited strong inhibitory activity against some important plant pathogenic fungi,including R.solani and F.oxysporum.The ability of B.subtilis JA to antagonize against the growth of the post-harvest pathogen -B,cinerea was tested in vitro.Spore germination of B.cinerea was strongly inhibited in the presence of JA cell suspension.Furthermore,B.subtilis JA can produce antifungal volatiles which strongly inhibited the spore germination and mycelial growth of B.cinerea.As a biocontrol agent,the synergic effect of lipopeptides and volatiles may play a major role in controlling the pathogens by B.subtilis JA.

Objective To evaluate the effects on trabeculectomy combined with implantation of anterior lens capsule.Design Radomized,controlled experimental study.Participants 36 experimental albino rabbits.Methods 36 albino rabbits were divided into 3 groups randomly.The rabbit and human anterior lens capsules were implanted under the scleral flap in trabeculectomy in group A and group B respectively,while only trabeculectomy in control group.The average follow-up period was 12 months.Main Outcome Mea- sures Intraocular pressures(IOP),filtering bleb,complications.Results The postoperative IOP of the experimental groups decreased sig- nificantly as compared with preoperative IOP at 12 week postoperatively.Retention of reflective filtering bleb in experimental groups was longer than that in contral group(5.12?0.43week,5.05?0.59week,2.74?0.32week,P＜0.05).The passage of humor outflow kept open in ex- perimental groups and became closed in control group at 12 week postoperatively.Anterior lens capsule wasn't attacked by T or B lym- phocyte seen with electron microscope.Conclusions Implantation of anterior lens capsule may help to postpone filtering bleb scarring in the trabeculectomy.This study provides experimental basis for the clinical practice.

Objective:To comparatively observe the effects of 20(R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on the Lewis lung cancer mice and to explore the mechanisms of Rg3 and PEG-PLGA-Rg3 nanoparticle anti-cancer in vivo.Methods:Lewis lung cancer mouse model was established and 60 mice were randomly divided into 5 groups with twelve in each group:PEG-PLGA-Rg3 nanoparticles group (Rg3-N),PEG-PLGA group (PEG),Rg3 group (Rg3 ),normal control group (C),saline control group(NS),and received intragastric administration for 1 4 days.The weights of the mice were measured every 2 days and the weight curves were obtained.At the same time,the color pattern,activity and men-tal status were observed.The mice were sacrificed when the administration was over,and the effects of 20 (R)-ginsenoside Rg3 and PEG-PLGA-Rg3 nanoparticles on tumor weight,and the tumor:weight ratios were analysed.In addition,the tumor microvessel density (MVD)was measured by immunohistochemi-cal staining with anti-CD31 antibody to compare the effects of Rg3 and PEG-PLGA-Rg3 nanoparticles on the tumor angiogenesis in vivo.Furthermore,the levels of such angiogenesis and proliferation factors as MMP-9,HIF-1 α,VEGF,Ki-67 were examined by RT-PCR,Western blot and immunohistochemistry to explore the internal molecular mechanisms of anti-tumor effects in vivo.Results:The trends of variation of the mice weights in NS group and PEG group were rising early but declining later.In contrast,the trends of the other three groups were rising early and became stable later.In comparison with NS group, the mice of Rg3 group and Rg3-N group had better general status:brighter color,more active and better spirit.Compared with NS group,the tumor weight in PEG group,Rg3 group and Rg3-N group showed no significant difference but the tumor:weight ratio and MVD in Rg3 group and Rg3-N group declined signi-ficantly (P <0.01 ).Besides,there was no significant difference between Rg3 group and Rg3-N group. At the same time,the level of VEGF mRNA,the protein expression of MMP-9,HIF-1 α,VEGF in Rg3 group and Rg3-N group decreased compared with NS group.Furthermore,the level of each index above-mentioned in Rg3-N group was lower than that in Rg3 group.The expression of Ki-67 in PEG group,Rg3 group and Rg3-N group showed no significant difference compared with NS group.Conclusion:Rg3 and PEG-PLGA-Rg3 nanoparticle may suppress the expression of VEGF,MMP-9 and HIF-1 αin Lewis lung cancer mice,thereby indirectly contributing to their antitumor effects and alleviating the mice’s general status.In addition,PEG-PLGA nanoparticles embedding can promote Rg3 antitumor effect in vivo.

Objective To explore the effect of empathy nursing on anxiety,depression and expectation of patients with myocardial infarction.Methods In our study,47 patients with myocardial infarction in the department of cardiology of our hospital from August 2013 to July 2014 were assigned as the control group and another 47 patients with the same disease during August 2014 to July 2015 as the study group.The control group received conventional nursing treatment and the study empathy nursing in addition to the conventional nursing.The two groups were compared in terms of anxiety,depression and expectation using Zung anxiety self rating scale (SAS),depression self rating scale (SDS) and Herth hope index (HHI).Results On admission,the patients in the two groups showed no differences in the levels of anxiety,depression and expectation (P＞0.05).After intervention,the levels of anxiety and depression in the study were significantly lower than those in the control group,but the level of expectation was higher (all P＜0.05).Conclusion Empathy nursing is effective for the relief of anxiety and depression in the patients with myocardial infarction as well as for their enhanced expectation for prognosis.

Purpose To quantitatively analyze the blood perfusion parameters after kidney transplantation with acute and chronic rejection by using contrast-enhanced ultrasonography (CEUS), in order to provide rapid assessment for rejection prognosis. Materials and Methods Thirty-one patients with kidney transplantation were followed up and divided into three groups according to clinical symptoms and graft biopsy results:normal group (n=6), acute rejection group (n=12) and chronic rejection group (n=13). CEUS was carried out to assess renal microcirculation perfusion. Results CEUS showed that the normal renal parenchyma was enhanced homogeneously whilst the rejected parenchyma was enhanced heterogeneously. The differences of area under the curve among the three groups was statistically signiifcant (F=37.102, P<0.01), with normal group >chronic rejection group > acute rejection group. The peak intensity in normal group was higher than that in acute rejection group (P<0.01), but it showed no difference with that in chronic group. In acute and chronic rejection groups, the arrival time and the time to peak intensity in interlobar artery and cortex were all later than those in normal group (P<0.05). The ascending slope of TIC in segmental artery, interlobar artery and cortex in the two rejection groups was both signiifcantly less than that in normal group. Conclusion CEUS is a valuable diagnostic tool in the evaluation of microcirculation perfusion in kidney graft, and can provide important reference for the prognosis of acute and chronic rejection after kidney transplantation.
