The paper analyses five medical moral conflicts of medical health reform. It indicates that connotation of the guide of value is collectivism and service to patients heart and soul. In order to guide value positively. 5 points should be noticed :a) To correctly recognize the dialectical relationship of medical health reform and medical moral engineering and keep equal engineering on them) b) To fully exert Medical education function of guiding benefits; c) To insist on socialist justice principle; d) To lead socialist competction into the reform; e) To carry out principle of "cutting benefits apart" and set up mechanism of dredging the tendency of benefits.

Objective To investigate the preventive effect of low molecular weight heparin or tranexamic acid in the rabbits with hypercoagulation induced by impact injury and intravenous infusion of the endotoxin. Methods Combination of impact injury and endotoxin was created by strike on rabbit chest with type BIM-Ⅱ biological impact machine and injection of endotoxin via vein.Thirty-two male New Zealand rabbits were divided into four groups in a completely random design as follows:impact injury combined with endotoxin without treatment group(control group),treatment with low molecular weight heparin(L group),treatment with tranexamic acid(TA group),and treatment with low molecular weight heparin and tranexamie acid(L+TA group).The changes of interleukin-1β(IL-1β)and interleukin-6(IL-6)were observed by using the enzyme-linked immunosorbent assay;changes of antithrombin-Ⅲ(AT-Ⅲ)activity,tissue factor(TF)and tissue factor pathway inhibitors(TFPI)were detected by the chromogenic substrate method chromozym P:the content of fibrinogen was observed by coagulation analyzer.The lung and kidney were removed from the experimental animals at 24 hours post impact injury forhistopathologic observation. Results In the control group,the activity of AT-Ⅲ was decreased obviously.while the content of fibrinogen and the activity of TF and TFPl were increased,with formation of the thrombosis in the kidney after injection of PLS.Compared with control group,the activity of TF and the content of IL-1β and IL-6 were reduced but the TFPI was increased in the L group,which resulted in a decrease of TF/TFPI ratio.with decrease of formation of the micro-thrombosis in the organs.The content of IL-1β and IL-6 in the TA group were reduced,which was still higher than that in tIle L group.In the TA group.the activity of IF and TFPI Was lower than that in the L group and control group,with higher TF/TFPI ratio than the L group.The frequency of thrombosis increased in pulmonary artery and other important organs.The content of IL-1β and IL-6 in the L+TA group wag lower than that in the L group.In the L+TA group.the activity ofTF was lower than that inthe L group and control group,but the activity of TFPI was higher than that in the L group and control group.with lower TF/TFPI ratio than the L group.There found no increase of thrombus in the pulmonary arterial and other important organs. Conclusions Besides anticoagulation function,the low molecular weight heparin can inhibit the inflanunation reaction,reduce the release of TF and attenuate the coagulation reaction.On the basis of treatment with low molecular weight heparin,application of the tranexamic acid will not lead to the formation of thrombus,but the only use of the tranexamic acid would have the contrary results.The rtsults of the study provide a theoretical and experimental basis for clinical diagnosis and prevention of hypercoagulation induced by injury and infection.

Objective To evaluate the effect of hydrodistension on interstitial cystitis and the psychological changes after hydrodistension.Methods Thirty two patients with interstitial cystitis underwent hydrodistension from May 2011 to Jun 2012 in Department of Urology,Beijing Hospital.Interstitial cystitis symptom index(ICSI),Visual onalogue Scale (VAS) pain score,quality of life questionnaire(QOL) score,self-rating anxiety scale(SAS) score,self-rating depression scale(SDS) score were recorded and analyzed before and at 1-3 month after hydrodistension surgery.The voiding diary and postoperative complications were cared.Results Symptoms were improved in twenty nine patients,the efficiency rate was 90.6％ (29/32).There were significant differences in ICSI score,VAS pain score,QOL score,SAS score,SDS score between pre and 3 month post-surgery [(26.7± 2.3) vs.(15.2±1.9),(4.6±2.5) vs.(1.8±1.1),(4.3±2.2) vs.(2.2±1.6),(53.8±3.7) vs.(40.8±2.3),(54.8±2.3) vs.(42.4±1.5),t=8.33,7.94,6.54,7.20,8.52,respectively,all P ＜0.05].No complication was found after surgery.Both the clinical symptoms and the anxiety and depression symptoms in patients were relieved,and QOL was improved.Conclusions For the patients with interstitial cystitis,the undergoing of hydrodistension surgery can relieve the anxiety and depression symptoms and improve quality of life.

Objective To study the changes of coagulation and fibrinolysis in rabbit model of non-overt disseminated intravascular coagulation induced by low-dose endotoxin and therapeutic effects of anticoagulation by heparin.Methods Twelve male rabbits were randomly divided into 2 groups,one receiving endotoxin intravenously(10 ?g/kg,n=6),one receiving endotoxin intravenously and 100 U/kg Heparin simultaneously(n=6).The blood sample obtained before experiment was used as control.Coagulation parameters including prothrombin time(PT),activated partial thromboplastin time(aPTT),thrombin time(TT),fibrinogen concentration,D-dimers,thrombelastography(TEG)were measured during 6 h after endotoxin induction.Tissue specimens of lungs and kidneys were examined.Results Parameters of coagulation deteriorated significantly in the endotoxin-induced rabbits,but was not altered in heparin-treated rabbits.TEG monitoring in the endotoxin-induced rabbits reflected consumption of clot factors and platelet dysfunction,and hypocoagulation status in heparin-treated rabbits.In endotoxin-induced group,fibrin deposition was found in lungs and kidneys.Conclusion Non-overt disseminated intravascular coagulation induced by low-dose endotoxin in rabbits is improved by heparin.

Objective To study the coagulation of patients with lung cancer or esophagus cancer in thoracotomy during perioperative period.Methods Variables [reaction time(R),clotting time(K),? angle,maximum amplitude(MA)]detected by thrombelastography were measured in 10 cases of lung cancer and 10 cases of upper or median esophagus cancer before anesthesia(T0),at the end of 1 h after operation beginning(T1)and 30 min after operation(T2).The control group consisted of 10 healthy volunteers.Results In lung cancer group and esophagus cancer group,R was shorter than control group(P

Thirty six patients aged 50-70 years with benign prostatic hyperplasia (BPH) received doxazosin and desmopressin treatment for 4 weeks.After treatment the International Prostate Symptom Scores (IPSS) and Quality of Life (QoL) scores of patients were significantly improved (17.4 ± 2.5 vs.11.8 ± 1.1 and 3.9 ±0.6 vs.1.8 ± 1.3,respectively;both P ＜ 0.01).The nocturia frequency was decreased from 4.6±1.5 to 2.1±1.6 (P＜0.01);nocturnal urine output from (564±73) to (348±45) ml (P＜0.05);the hours of undisturbed sleep increased from (88.6 ± 17.5) min to (146.2 ± 12.8) min (P ＜0.05).There were no significant differences in serum levels of sodium,potassium and chlorine,and osmoticpressure before and after treatment.The results indicate that doxazosin combined with desmopressin is safe and effective for treatment of nocturia in patients with BPH.

Objective To investigate the value of carotid and lower limbs arteries atherosclerosis in prediction of intracranial atherosclerosis combined with type 2 diabetes (T2DM). Methods Seventy-four patients with T2DM received the carotid artery , lower limbs arterial color Doppler ultrasound and cranial MRA examination. The data was analysised by Pearson correlation and Binary Logistic methods. Results With the increasement of degree of peri-arterial atherosclerosis , the intracranial arteriosclerosis was in a trend of increase. The correlation coefficients, OR values and AUC of LLAS and CAS + LLAS for intracranial atherosclerosis were 0.28 (P < 0.05) and 0.33 (P < 0.05), 0.14 (P < 0.05) and 9.28 (P < 0.05), 70.30% (P < 0.05) and 70.60% (P < 0.05), respectively. The cut-off point of LLAS and CAS + LLAS was lever 2. Conclusion The LLAS and CAS + LLAS with T2DM are independent risk factors for intracranial atherosclerosis , owning certain forecast values.

Laparoscopic vagal-sparing esophagogastrectomy for the treatment of early esophageal cancer has the advantages of minimal invasion,functional sparing and better quality of life,and it can radically resect the tumor.The clinical data of 3 patients in the Daping Hospital of Third Military Medical University and 9 patients in the Xijing Hospital of Digestive Diseases who received laparoscopic vagal-sparing esophagogastrectomy from September 2009 to August 2013 were retrospectively analyzed.All the 12 patients were followed up for 1-24 months.One patient was complicated with transit hoarseness and 1 with cervical anastomotic fistular,and they were cured by conservative treatment; 1 patient was complicated with cervical anastomotic stricture,and was cured by dilatation for 3 times; no dysphagia and recurrence was observed in the other 9 patients during the follow-up.Laparoscopic vagal-sparing esophagogastrectomy is a good option for early esophageal cancer and benign esophageal diseases.

Objective To evaluate the modularized operative process during video-assisted thoracoscopic esophagectomy for esophageal cancer.Methods The clinical data of 45 patients with esophageal cancer who were admitted to the Daping Hospital from December 2011 to December 2012 were retrospectively analyzed.The influence of modularized operative process on the intra-and post-operative condition and short-term complications after videoassisted thoracoscopic esophagectomy + esophagogastric anastomosis were analyzed to investigate the efficacy and value of modularized operative process.Patients received video-assisted thoracoscopic and laparoscopic resection of esophageal carcinoma or thoracoscopic resection of esophageal carcinoma + gastric mobilization.Thoracoscopic esophageal mobilization and mediastinal lymph nodes dissection were done according to the modularized operative process:(1) Pulmonary ligament mobilization and groups 8L and 9 lymph nodes dissection.(2) Mobilization of the esophagus under the arcus venae azygos.(3) Mobilization of esophagus above the arcus venae azygos.(4) Transection of the arcus venae azygos.(5) Complete removal of thorax esophgus.(6) Ligation of thoracic duct.(7) Dissection of groups 4,5,7,10 and 2L lymph nodes.All the patients were followed up via phone call or mail till February 2013.Patients received thoracoabdominal computed tomography and gastrofiberscopy to detect tumor recurrence or metastasis every 3 months within the first year after the operation,and they were re-examinated every half year at 1 year later.Results Of the 45 patients,29 received video-assisted thoracoscopic and laparoscopic resection of esophageal carcinoma and 16 received video-assisted thoracoscopic resection of esophageal carcinoma + gastric mobilization.The length of the tumor was (4.2 ± 2.5) cm.The numbers of patients in AJCC T1,T2,T3 and T4 stages were 7,14,15 and 9,and the number of patients with AJCC N0,N1,N2,N3 stages were 23,13,7,2,respectively.The intrathoracic operation time,total operation time,volume of intraoperative blood loss,number of lymph node resected and postoperative duration of hospital stay were (72 ± 13)minutes,(249 ± 39) minutes,(183 ± 62) ml,27 ± 7,(18 ± 7) days,respectively.Two patients were transferred to open surgery.No patient died postoperatively,and 11 complications were detected after the operation.Six patients were complicated with cervical anastomotic fistula,4 with anastomotic stricture and 3 with hoarseness.Forty-five patients were followed for 1.5-14.0 months with the median follow-up time of 8 months.One patient died of upper gastrointestinal hemorrhage at postoperative month 12,and 1 died of multi-organ dysfunction syndrome at postoperative month 8.The remaining 43 patients survived.Conclusions The modularized operative process for thoraeoscopic esophagectomy is safe and effective,its short-term efficacy is satisfactory.

ObjectiveTo investigate the association between the common variant rs1512268 single nucleotide polymorphism(SNP) of NKX3.1 gene and the risk of prostate cancer,and to explore its interaction with related risk factors.MethodsTotally 122 patients with prostate cancer and 105 age matched male people (prostatic specific antigen ＜ 4 μg/L,without family history of prostate cancer) as control group were enrolled.Polymerase chain reaction - high resolution melting curve(PCR - HRM) combined with gene sequencing methods were used to determine the distribution of allele and genotype frequencies of the rs1512268 SNP.ResultsThe distributions of GG,AG,AA genotypes were 42 cases(33.4％),66 cases(54.1％),14 cases(11.5％) in patients with prostate cancer,and 45 cases(42.9％),51 cases(48.6％),9 cases(8.6％) in healthy control,respectively.There were no significant differences in the distribution of genotype(x2 =1.70,0.69,0.52) and allele frequency (x2 =1.575) between the two groups(P＞ 0.05).The different genotypes of rs1512268 of NKX3.1 gene were not associated with age,Gleason score,PSA levels and clinical stage of prostate cancer (P＞0.05). Conclusions rs1512268 SNP of NKX3.1 gene is not obviously associated with prostate cancer and may be not the genetic risk factor in Chinese.
