OBJECTIVE: To probe into the status quo and future tendency of utilization of cardiovascular drugs in hospital of high altitude area. METHODS: Consumption sum and DDDs of cardiovascular drugs used in our hospital were analyzed statistically during 2006～2008. RESULTS: Consumption sum of cardiovascular drugs was increased year by year as well as its percentages in the total consumption sum. Top 10 cardiovascular drugs in terms of consumption sum mainly included antianginal drugs, antihypertensive drugs, blood fat harmimegathy drugs and antithrombotics drugs. Consumption sum of antianginal drugs which had occupied 44% in that of cardiovascular drugs took the dominate place in three years. Consumption sum of antihypertensive drugs was increased fast as well as its percentage in cardiovascular drugs about more than 20%. Consumption sum of antithrombotics drugs had occupied about 22%. CONCLUSION: Requirement of cardiovascular drugs was increased year by year. Cardiovascular drugs from foreign countries and joint stock take main place. It is necessary to explore domestic substitute drugs to decrease the cost of cardiovascular drugs.

Objective To evaluate the significance of immediate early 1 (IE) mRNA detection by nucleic acid sequence-based amplification (NASBA) in the diagnosis of human cytomegalovirus (HCMV) infection after renal transplantation.Methods The expression of IE-mRNA and pp67-(mRNA) was detected by NASBA in 55 patients after renal transplantation, and pp65 antigenemia (assays) were done for all cases.Results Twenty cases were positive for IE-mRNA. Thirteen cases were suffered from CMV disease with symptoms. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of IE-mRNA by NASBA were 92.3 %, 80.9 %, 60.0 % and 97.1 %, respectively. Time to first IE-mRNA positive detection after transplantation was shortest, compared with pp67 and antigenemia (P

Objective To evaluate hemodynamic status,pathological,imaging and ultrasound changes of residual lymph nodes from diffuse large B-cell lymphoma (DLBCL) after chemotherapy and their relationship with clinical treatment after chemotherapy.Methods 50 DLBCL patients undergoing full course of chemotherapy but still bearing residual lymph nodes were examined with ultrasound-guided lymph node biopsy.Some examinations were combined with PET-CT to analyze properties of residual lymph nodes.Results 64 lymph nodes were identified by color Doppler ultrasounda in the 50 DLBCL patients treated with full course of chemotherapy.Among them,53 lymph nodes from 42 patients did not show artery blood flow and HE staining of these lymph node biopsy met the clinical standard for complete remission.For the other 11 lymph nodes from 8 patients,ultrasound examination displayed smrounding blood flow inside.At the same time,PET-CT showed that these lymph nodes had higher SUV values,implying high metabolic state in these tissues,which was in agreement with ultrasonic examination results.However,HE staining of these lymph nodes biopsy demonstrated only residual lesion but no tumor tissue.Conclusions Lymph nodes still exist in DLBCL patients treated with full course of chemotherapy.Ultrasound and PET-CT examination have high accuracy in diagnosing benign and malignant residual lymph nodes in follow-up examination on 4 weeks after chemotherapy showed that lymph nodes are over ＞ 1.5 cm in length and have central or peripheral blood flow.Therefore,PET-CT examination of tumor could be considered as a reference index in characterizing residual tumors after chemotherapy.

Objective To evaluate carbon lymph tracer (CH40) in pancreatic cancer surgery.Method 61cases of pancreas head carcinoma undergoing whipple procedure from June 2011 to December 2013 were divided into intraoperative nano carbon group (group A,36 cases),in which resection range was adjusted according to lymph node staining including 13 standard resection cases (group A1),and 23 modified extended radical resection cases (group A2).Standard group (group B,n =17),and extended radical operation group (group C,n =8),respectively.Results The average lymph nodes harvested in group A1 were 25.08 ± 2.72,with positive lymph nodes of 7.92 ± 2.22,significantly more than group B (19.47±1.55,2.68 ±5.24),P＜0.05.In group A2,the average lymph node was 29.91 ±2.68,positive lymph node was 11.04 ± 2.38,significantly more than group C (25.13 ± 2.85,8.49 ± 3.32),P ＜0.05.The mean survival time and overall survival time of group A1 were 43.80 ±4.09 months,51.44 ±1.64 months,significantly more than group B (27.11 ±3.36,41.74 ±3.28 months),P ＜0.05.In group A2,the average tumor free survival time,and overall survival time was 31.58 ±2.99 months,45.02 ±2.54 months,not statistically different with group C (29.13±4.76 month,43.67 ±3.33 months),P ＞0.05.Conclusions Intraoperative lymphatic tracer technology significantly increases lymph node harvest,improving the survival time and tumor free prognosis.

Objective To assess the feasibility and accuracy of transesophageal echocardiography (TEE) in screening patients,intraoperative guidance of occluder releasing and efficacy assessment in the patients of percutaneous left atrial appendage (LAA) occlusion with Watchman.Methods Ultrasonic instrument Philips iE33(proble model X7-3t) were used to measure the maximum diameter and the depth of LAA ostium in enrolled patients by TEE,and intraoperative guided puncture of interatial septum,positioning Watchman transmission system and instruction closure release under TEE,immediate evaluate the postoperative therapeutic effect and record the complications by TEE.At 45 days after implantation,patients should repeat TEE to assess the efficacy.Results Eighteen patients underwent device implantation.Seventeen patients implant successfully,except one patient can't implant device beacuse of the LAA morphologe was not suitable.There was one patient showing thrombus formation on the surface of device,one patient of LAA and the device axial angulation was 90 °.At 45 days after implantaion,16 patients were fullowed up,there were no major stroke at all.Conclusions TEE has important application value in screening of preoperative patients,intraoperative guidance of occluder releasing and efficacy assessment in the patients of percutaneous left atrial appendage occlusion with Watchman.

Objective To evaluate right ventricular function of chronic thromboembolic pulmonary hypertension (CTEPH) patients by echocardiography and cardiac magnetic resonance (CMR),and to evaluate the value of clinical application of those right heart function indexes.Methods 32 patients with CTEPH who underwent CMR and echocardiography were involved in the study.Right ventricular index of myocardial performance (RIMP),fractional area change (FAC),tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler-derived tricuspid lateral annular systolic velocity (S') were measured by echocardiography.Right ventricular end-diastolic volume (RVEDV) and end-systolic volume (RVESV) were measured by cardiac magnetic resonance and right ventricular ejection fraction (RVEF) was calculated.Results A positive correlation was found between FAC and RVEF (r =0.423,P =0.022),there was a negative correlation between RIMP and RVEF (r =-0.387,P =0.048),there was no correlation between TAPSE and RVEF (r =0.451,P =0.22),a positive correlation was found between S' and RVEF (r =0.689,P =0.000).Conclusions The echocardiographic parameters FAC,RIMP and S' can reflect right ventricular function in patients with CTEPH and can be used as a routine clinical parameters.

Objective:To observe the effect of stereotactic aspiration combined with corresponding drug therapy in the treatment of cerebral hemorrhage induced by different drugs. Methods:Totally 66 patients with hemorrhage induced by antithrombotic drugs were randomly divided into the control group and the treatment group with 33 cases in each. The control group was given corresponding drug therapy according to the pathogenesis of cerebral hemorrhage, and the treatment group was treated by stereotactic hematoma aspiration additionally. Daily life ability, NIHSS and prognosis improvement were compared between the two groups before and after the treat-ment. Results:After the treatment, NIHSS of the treatment group was ( 10. 17 ± 2. 97 ) and Barthel index score was ( 59. 97 ± 12. 10), which were both better than those of the control group (P<0. 05). The prognosis of the treatment group was also better than that of the control group (P<0. 05). There was no severe adverse drug reaction in the two groups. Conclusion:For different drug in-duced cerebral hemorrhage, corresponding drug therapy should be carried out, and combining with stereotactic hematoma aspiration, the therapeutic regimen can effectively improve neurological deficits and activities of daily living of the patients, and then improve the prognosis of the patients with promising safety.

AIM To study antitumor activity of the extract denominated as UAP(Uric Antitumor Peptides isolated and purified from normal human urine). MOTHODS Proliferation inhibition assay was examined by cell counting and MTT method. Experiments in vivo were tested by treatment on tumor mice and acute toxicity on healthy mice. RESULTS UAP exerted strong dose dependent inhibition on the proliferation of three tumor cell lines, but not human normal leucocytes. Treatments on tumor mice show that UAP effectively inhibited tumor growth of mice HAC hepatoma, mice Lewis lung carcinoma and mice S 180 sarcoma with apparently dose dependent effect. Acute toxicity proved that UAP had very low acute toxicity in mice with LD 50 = 2 137 13 mg?kg -1 . CONCLUSION UAP has strong antitumor activity in vitro and in vivo. This provides a promising alternative antitumor treatment.

A case with the diagnosis of the onset of inflammatory bowel disease (IBD) with chronic granulo-matous disease (CGD) in Children′s Hospital Affiliated to Zhengzhou University in June 2016 was chosen, and the patient′s clinical data and whole treatment process were analyzed.According to the relevant literature from Chinese and foreign databases, the clinical characteristics were analyzed and summarized, principles of diagnosis and treatment for children who had the onset of IBD with CGD.This patient was a child of 1 year and 9 months old, and the initial symptoms included repeated diarrhea and bloody stools.He was diagnosed as " ulcerative colitis" in the local hospital.After admission, the neutrophil respiratory burst test was positive.The genetic analysis result suggested that the CYBB gene was mutated, thus obtaining the diagnosis of CGD.Then, he was given prophylactic antibiotic therapy and symptomatic treatment.After the 3 months of follow-up after discharge, the patient still had intermittent diarrhea and bloody stools.CGD is a rare primary immunodeficiency disease, and current treatment methods of CGD include hematopoietic stem cell transplantation and anti-infection treatment.When IBD patients have complications other than gastrointestinal symptoms, the IBD treatment is not effective, or there are suspected parents who are married to close relatives, or with the family history of IBD, CGD should be considered.
