Objective To investigate the value of Helicobacter pylori (HP),blood carcinoembryonic antigen (CEA),carbohydrate antigens 72-4 (CA72-4) and CA24-2 in the screening of gastric cancer.Methods The contents of HP,blood CEA,CA72-4 and CA24-2 in 50 healthy controls,45 patients with benign gastric lesions mnd 70 patients with gastric cancer were detected.According to the number of positive cases,the positive rate of single detection and the positive rate of combined detection were calculated.Sensitivity,specificity,and accuracy of serum tumor markers were calculated according to HP single and combined detection.Results The positive rate of each individual detection and 4 joint detection in gastric cancer group was significantly different from that in the benign lesion group and the normal control group (P ＜0.01).The positive rate of 4 joint detection in gastric cancer group was 89.25％,and the difference was statistically significant (P ＜0.01).There was no significant difference in the positive rate of the single test and the 4 joint detection in benign stomach group and normal control group (P ＞ 0.05).The sensitivity,specificity and accuracy of HP,blood CEA,CA72-4,CA24-2 joint detection were significantly higher than single detection (P ＜ 0.05).Conclusions Joint detection was significandy better than single detection,and can significantly improve the detection rate of gastric cancer.

Objective To investigate the clinical and pathological features of colonic polyp canceration and related risk factors of colon polyps,and explore clinicopathologic features and major risk factors of the canceration of polyps of colon polyps.Methods Totally 80 patients with colon polyps including 6 cases of cancerations and 20 patients with colon cancers were selected from Xuzhou Tumor Hospital Admissions.Those patients were divided into 74 cases of non cancer group and 26 cases of cancer group.The clinical data,the detection index and the statistical analysis were performed.Results The clinical features of patients included 51 cases of multiple polyps,30 cases of fatty liver,13 cases of fecal occult blood positive,and 30 patients with colonoscopy.There were 218 polyps,191 data intact,and 6 cases showed cancer (3.14％).Inflammatory polyps mainly occurred in rectum,cecum,and significant risk other than the colon.Tubular adenoma occurred mainly in the transverse colon.Sigmoid colon cancer colon polyps of the highest risk showed OR =2.30 (P ＜ 0.05).The cancer risk from high to low was from tubular villous adenoma to villous adenoma hair (P ＜0.01),and no difference in tubular adenoma cancer risk (P ＞0.05).There was no difference between the indexes of the canceration group and the non cancerous group (P ＞ 0.05).The single factor analysis showed pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Multi-factor regression analysis showed WBC,pathological type,and the lesion were the main risk factors of malignant colonic polyps (P ＜ 0.05).Conclusions The colonic polyps in male have higher incidence with fatty liver,hypertension and other pathological features,and are mainly tubular adenomas,inflammatory and hyperplastic polyps,with different lesions,pathological types occur and different cancer risk.

Objective To explore the effect and adverse reaction of different neoadjuvant chemotherapy regimens:docetaxel + THP + cyclophosphamide and docetaxel + THP in the treatment of triple negative breast cancer.Methods The clinical data of 75 patients with triple negative breast cancer in type Ⅱa-Ⅲc period were retrospectively analyzed.According to different treatment method,they were divided into two groups.The observation group (43 cases)was given the treatment of TAC,the control group (32 cases) was given the treatment of AT.The short-term efficacy and adverse reaction were evaluated and analyzed before every course of treatment,the total effective rate was evaluated after four courses of treatment.The long-term curative effect of the two groups was evaluated by following-up.Results The total effective rate of the observation group was 90.70％,which was significantly higher than 71.88％ of the control group (x2 =4.536,P =0.033).The incidence rates of adverse effects of chemotherapy in the observation group were higher than the control group,but there were no statistically significant differences between the two groups (gastrointestinal disorder x2 =2.931,P =0.087;marrow depression x2 =1.586,P =0.208;baldness x2 =1.367,P =0.242;cardiotoxicx2 =1.114,P =0.291).The three years survival rates in the observation group and the control group were 93.02％ and 87.50％ respectively,there was no statistically significant difference between the two groups(x2 =0.940,P =0.332).Conclusion The neoadjuvant chemotherapy of TAC and AT is both effective in the treatment of triple negative breast cancer,and TAC scheme is superior to AT scheme,the long-term efficacy in the two schemes has no significant difference.

OBJECTIVE:To determine the solubility and apparent oil and water partition coefficient (lg P) of saponin H1,and provide reference for dosage form design and druggability research of saponin. METHODS:HPLC-ELSD was conducted to deter-mine the equilibrium solubility of saponin H1 in different organic solvents and pH buffer solutions;shaking flask was applied to de-termine lg P value of saponin H1. RESULTS:The equilibrium solubility of saponin H1 in water,methanol and ethanol at 25 ℃ was 0.09175 g/L,96.51 g/L and 46.89 g/L,respectively. The solubility increased apparently at high pH within pH range at 7.6-10.0;the lg P value was between 0.695-0.773 in buffers within pH range at 6.0-8.0. CONCLUSIONS:Saponin H1 and the oleanolic acid type saponins belong to low solubility, low transmission components, so it is not suitable for use as a conventional oral formulation is developed.

Objective To explore the prognostic value of serum C-reactive protein/albumin (CRP/ALB) ratio in the adult patients with sepsis.Methods A retrospective study was conducted.Clinical data were collected from septic patients who were at least 18 years old and whose intensive care unit (ICU) lengths of stay were at least 3 days,and who were admitted in the Department of Critical Care Medicine of the First Affiliated Hospital of Zhengzhou University in Henan Province from September 2013 to September 2015.These patients were divided into survival group and death group according to 28-day outcome.The serum CRP,ALB,and CRP/ALB ratio levels at the start of treatment (0 hour),24 hours and 72 hours after treatment in ICU were analyzed.And the receiver-operating characteristic (ROC) curve was plotted to assess the value of CRP,ALB and CRP/ALB ratio at different time points for predicting the outcome.Results Sixty-nine patients with sepsis were selected,among whom 28 cases were in the death group and the mortality was 40.6％.The characteristic of the baseline data in the two groups was balanced.The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sequential organ failure assessment (SOFA) score at the first 24 hours of ICU admission in the death group were significantly higher than those in the survival group (APACHE Ⅱ score:25.18 ± 3.18 vs.17.88±3.20,SOFA score:11.71± 1.78 vs.9.17 ± 2.38,both P ＜ 0.05).And the ICU length of stay in the death group was significantly longer than that in the survival group [days:9.0 (2.5) vs.8.0 (3.0),P ＜ 0.05].The ALB level increased gradually as the treatment was extended in both groups while the levels of CRP and CRP/ALB declined gradually.The ALB levels at 0,24,72 hours after treatment in the death group were significantly lower,and the CRP and CRP/ALB levels were significantly higher than those in survival group [ALB (g/L):23.40 (4.20) vs.25.20 (8.20) at 0 hour,24.18±4.33 vs.28.54±4.88 at 24 hours,25.50±4.88 vs.34.88±7.23 at 72 hours;CRP (mg/L):179.32±34.04 vs.159.55±36.82 at 0 hour,160.08±22.91 vs.146.23±30.31 at 24 hours,159.36±25.81vs.142.53±36.30 at 72 hours;CRP/ALB:7.52±1.32 vs.6.04±1.46 at 0 hour,6.77±1.42 vs.5.23±1.24 at 24 hours,6.40± 1.34 vs.4.19± 1.21 at 72 hours;all P ＜ 0.05].ROC curves analysis showed that the area under ROC curves (AUC) of CRP/ALB at all time points were larger than those of CRP and ALB,with higher sensitivity and specificity;the AUC of ARP/ALB at 0,24,72 hours were 0.767,0.807,0.895,respectively;the cut-off values were 6.96,5.44,4.91,the sensitivity were 71.4％,85.7％ and 89.3％,and the specificity were 73.2％,63.4％ and 82.9％,respectively.Conclusions High serum CRP,CRP/ALB and low ALB in adult patients with sepsis indicate a poor prognosis,while the prognostic value of CRP/ALB is obviously better than the single value of CRP or ALB.CRP/ALB at 72 hours may be one of the best indicators for the assessment of clinical therapy and prognosis of patients with sepsis.

County -level public hospitals reform is an important measure of deepening reform of the medical and health system.Medicare payments system reform is therefore an important part of public hospitals reform.By abolishing drugs addition,registration fee,treating fee and setting up medical service fee instead,our hospital carried on a diversified management style in the aspect of medical insurance total prepaid system.The implementation of the reform measures turns out a good result:reasonably keeping a control on the medicare spending and really embodying the transformed of interests patterns.On the premise of ensuring patients interests,medical personnel′s interests are improved to a new level and medical insurance fund are also brought under a reasonable control.The medicare payments system reform puts equity in access and people benefit as the starting point and footing of county -level public hospitals reform,thus lays a foundation of further development of public hospitals reform.

Objective:To observe the effects of active immunization with a synthesized repetitive peptides in the extracellular loops of Na/Ca exchanger(NCX)?1 on cardiac structure and function in rats.Methods:A repetitive peptide of 124 HNFTAGDLGPSTIVGSAAFNMF145 was synthesized,which was in line with the extracellular loops of Na/Ca exchanger(NCX)?1.Healthly male Wistar rats of 2 month age were immunized actively with the synthesized peptide as antigen repeated for 12 weeks.The control group was given Freund's adjuvant only.Specific antibodies were detected by ELISA.The cardiac function was observed by Langendorff isolated heart-perfusing assay and the hearts were prepared for routine histological evaluation.Results:All rats immunized with the peptide developed highly positive autoimmunities,indicated by the antibody titers.After 12 weeks of peptide inoculation,the cardiac functioning indexes including LVSP-LVDP,+dp/dtmax and -dp/dtmax increased much more significantly in immunized group than in control.Histological evaluation showed that the myofilaments of the control group arranged regularly and densely with better continuity,whereas the myofilaments of the immunized group were lined with disorder.Some of those were ruptured.The interstitial lymphocyte infiltration was observed.Conclusion:The results indicate that long term immunization with the synthesized repeatitive peptide in line with the extracellular parts of Na/Ca exchanger(NCX)?1 can enhance both systolic and diastolic function of rat heart,but it can also induce injury in the heart structure.This may relate with an increase of myocardial oxygen consumption owing to a long time and continued excitement of membrane ion transporters as well as their active effect in heart contraction to a larger extent.

Objective:To summarize the experience in diagnosis and treatment of primary cardiac tumors in pediatric patients.Methods:Retrospectively analyzing 7 pediatric patients who were suspected as primary cardiac tumors and diagnosed and treated in Department of Heart Center, Children′s Hospital of Dalian Medical University from August 2013 to February 2019.All patients underwent echocardiography and other examinations, so as to confirm the diagnosis and the treatment plan was chosen based on the size and location of the tumor.All patients were followed up after discharge.Results:A total of 7 patients were diagnosed as primary cardiac tumors by echocardiography, among which 5 cases underwent surgical treatment, and 2 cases were diagnosed with tuberous sclerosis without surgery.In children undergoing surgery, 1 patient underwent autologous heart transplantation to remove the tumor, 1 patient had arrhythmia, 1 patient had mitral regurgitation after surgery, and the mitral regurgitation was corrected again.The remaining children had no adverse complications and were discharged successfully.Histologic examination revealed rhabdomyoma in 4 patients, and fibroma in 1 patient.The patients were followed up for 2-66 months after discharge, and no tumor recurrence was observed in the children who performed surgery.There was a trend of spontaneously regress of cardiac tumor in 2 patients without surgery.Conclusions:Echocardiography is the first choice for the diagnosis of primary cardiac tumors in Pediatric patients.Rhabdomyoma is the most prevalent histologic type of primary cardiac tumors, and tuberous sclerosis should be excluded during the diagnosis process.Patients with tuberous sclerosis selected conservative treatment, and surgical treatment was selected for children with obvious symptoms.According to the location and size of lesion, therapy strategies should be chosen and autologous heart transplantation can be adopted to remove the tumor for children with large tumors.Autologous heart transplantation to remove the tumor is a good surgical treatment.

Objective To investigate the efficacy and safety of percutaneous patent ductus arteriosus (PDA) closure via femoral vein solely under transesophageal echocardiography guidance.Methods From May 2014 to May 2015,28 patients(13 boys,15 girls) were selected in Dalian Children's Hospital Affiliated to Dalian Medical University with PDA closure via the femoral vein under transesophageal echocardiography guidance,with mean age (3.5 ± 2.6)years and mean body weight (16.0 ± 6.5) kg.The mean diameter of PDA was (7.1 ± 3.9) mm.Patients were all treated by percutaneous PDA closure solely by transesophageal echocardiography via the femoral vein.The effect of the procedures was evaluated by echocardiography.The transthoracic echocardiography,chest X-ray film,cardiogram at 1 month,3 months and 6 months after procedure were followed up.Results Twenty-seven cases were successfully treated with percutaneous PDA closure via the femoral vein solely under transesophageal echocardiography guidance,while 1 patient was closed by surgical closure with on-pump beating-heart because PDA occluder strayed into the left pulmonary artery on 1-month follow-up.The procedural time was (48.5 ±8.7) min.The mean diameter of PDA occluder was (8.2 ± 4.1) mm.Twenty-seven patients survived without peripheral vascular injury or complications such as residual shunt,arrhythmia and cardiac perforation.One patient was transformed to surgical closure.Hospitalization time was (2.5 ± 0.5) days.At one month follow-up,no complications such as residual shunt or pericardial effusion occurred.Conclusion Transesophageal echocardiography guided percutaneous PDA closure via the femoral vein approach is safe and effective without the damage from radiation and contrast agents,and aviods the use of femoral artery puncture.

Objective To compare the treatment effect between Duply combined with Duckett and Koyanagi surgical methods in severe hypospadias.Methods Forty-two cases of severe hypospadias were divided into two groups according to the surgical method,23 cases was enrolled in Duply combined with Duckett group while 19 cases in Koyanagi group.The operation time,the incidence rate of urinary fistula,urethral stricture,urethral diverticulum and penis torsion were compared.Results The operation time between two groups had no significant difference (P ＞ 0.05).The incidence rate of urinary fistula,urethral stricture,urethral diverticulum and penis torsion between two groups had no significant difference (x2 =0.04,0.31,0.03,1.16,P ＞ 0.05).The total incidence rate of complications between Duply combined with Duckett group and Koyanagi group had significant difference [69.6％ (16/23) vs.6/19] (x2 =4.59,P ＜ 0.05).Conclusion Each of the two methods can be a choice in treatment of severe hypospadias.
