Objective To investigate the efficacy of esomeprazole (Esomeprazole) and flupentixol and melitracen (Deanxit) in treatment of non-erosive gastroesophageal reflux disease (NERD) with depression and anxiety.Methods The diagnosis of NERD was based on the results of esorneprazole scale (reflux diagnostic ques- tionnaires,RDQ) and endoscopy,the degree and frequency of symptoms were graded and scored.Hamilton de- pression scale was used to evaluate depression and anxiety status.Sixty-three patients were randomly divided into group A (esomeprazole 20 mg qd),B (Deanxit 1 tab qd),C (esomeprazole 20 mg qd and Deanxit 1 tab qd) with each group 21 patients,and treated for four weeks.The efficacy was evaluated by the symptom scores.Results There were some effects of esomeprazole or Deanxit alone on the improvement of symptoms of NERD.Although the effect of Deanxit was not as good as esomeprazole,there was not difference for relieving heartburn and sub- sternal pain between two groups in time point of each week after treatment (P＞0.05).esomeprazole was better for relieving acid regurgitation than Deanxit (P＜0.01).Combined treatment of esomeprazole with Deanxit was better and faster for relieving the symptoms of NERD than esomeprazole or Deanxit alone (relieving rate 81% in group C,23.8% in group A and 14.3% in group B,P＜0.01).The total efficacy rate of group C (100%) was higher than that of group A (80.9%) or group B (61.9%,P＜0.01),but there were not difference of relieving rate and total efficacy rate between group A and B (P＞0.05).Conclusions There was better efficacy of com- bined treatment of esomeprazole and low-dose Deanxit in treating NERD with depression and anxiety.These re- sults suggest that depression and anxiety have some effects on the pathogenesis and progress of NERD.

Objective To explore the genetic defects in patients with pulmonary atresia (PA).Methods Twenty-three patients with PA were studied from recent 1 year.There were 15 boys and 8 girls,aged 2 days to 10 years.Among them,there were 3 cases with complete ventricle septum,20 cases with VSD,3 cases without main pulmonary trunk,20 cases with PDA,6 cases with integrated major aorto-pulmonary collateral arteries(MAPCAs),3 cases with integrated right aortic arch,2 cases with integrated extra-cardiac abnormality with the manifestation of facial abnormality,1 case with integrated aberrant right subclavian artery,and 1 case with integrated tracheal bronchus.The chromosomes of the children were routinely analyzed.Negative chromosomes were examined to identify the 22ql 1.2 microdeletion by fluorescence in situ hybridization (FISH) test.Results One case of trisomy syndrome was found.22ql 1.2 microdeletion was found in 3 cases.Among 22q1 1 microdeletion cases,1 case was intact ventricular septum,2 cases were integrated VSD.22q1 1.2 microdeletion was not found in the rest 19 cases.Conclusions Twenty-one trisomy syndrome and Del 22q1 1.2 syndrome may play an important role in the pathogenesis of PA.TBX1 probe can be used to examine 22q1 1.2 microdeletion.Del 22q1 1.2 syndrome was suspected in cases of incorporating aberrant subclavian artery,MAPCAs and severe poor development of pulmonary artery.

Objective To investigate the efficacy and safety of Urinary kallidinogenase(UK)combined with butylphthalide in patients with acute cardioembolic stroke(ACS).Methods A retrospective collection was performed for ACS patients diagnosed and treated in Hangzhou First People's Hospital from May 2022 to April 2023.According to the treatment protocol,ACS patients were divided into UK group and Butylphthalide+UK group.The clinical efficacy,neurological function,serum indexes(Hcy,NT-proBNP and VEGF)and prognosis of the two groups were compared after 2 weeks of treatment.Results A total of 86 ACS patients were included in the study,including 43 in the UK group and 43 in the Butylphthalide+UK group.After treatment,the total effective rate of treatment in the Butylphthalide+UK group was significantly higher than that in the UK group(P<0.05),and there was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).In addition,the expression levels of Hcy and NT-proBNP in ACS patients in the Butylphthalide+UK group were significantly lower than those in the UK group(P<0.05),while the expression levels of VEGF were significantly higher than those in the UK group(P<0.05).The NIHSS score and mRS score of ACS patients in the Butylphthalide+UK group were significantly lower than those in the UK group(P<0.05).The rate of collateral circulation establishment in the Butylphthalide+UK group was significantly higher than that in the UK group(P<0.05).Conclusion Butaphthalide combined with UK has significant efficacy and high safety in ACS patients,which may be achieved by regulating the expression levels of serum Hcy,NT-proBNP and VEGF,thereby improving neurological function and promoting the establishment of collateral circulation.

OBJECTIVETo observe the mechanical properties of decellularized porcine aortic valve, and to explore the effects of precoating methods of biological scaffold on histocompatibility.

METHODSFresh porcine aortic valves were decellularized using trypsin, TritonX-100 and nuclease. Treated valves were evaluated by light microscopy, scanning electron microscopy (SEM) and mechanical test. Three groups of scaffold were precoated with phosphate buffered saline (PBS), poly-L-lysine (PLL) and fetal bovine serum (FBS) respectively. Myofibroblasts were seeded onto each scaffold. Light and electron microscopic observation was performed and MTT test was used to examine efficiency of cell attachment.

RESULTSHE stain and SEM showed that cells were almost absent in the treated leaflet. The wave-like collagen together with the whole three-dimensional structure was maintained. Compared with normal valves, the Max-load, Max-stress and elastic modulus decreased while the Max-strain increased (P<0.05). The result of MTT test showed more cells were attached on the valves treated with FBS compared to the other two groups. Histological investigations also confirm that the high degree of cell attachment on the valves precoated with FBS (F=129.26, P=0.000).

CONCLUSIONSEnzyme combined with detergent and nucleases can remove cells from porcine aortic valves. Meanwhile the mechanical properties of these valves may be altered. Precoating porcine aortic valve with FBS is an effective method to improve cell attachment, growth and increasing.

OBJECTIVETo analyze microarray datasets deposited in the public database and to identify TNM associated genes in gastric cancers.

METHODSMicroarray datasets of gastric cancer were selected from GEO database. Differentially expressed genes related to TNM staging were evaluated by significant analysis of the microarray using MultiExperiment Viewer (MEV) platform. Candidate gene expressions in gastric cancer tissues and cell lines were verified by reverse transcriptase polymerase chain reaction (RT-PCR), quantitative RT-PCR, Western blot and immunohistochemistry.

RESULTSGES4007 dataset was re-analyzed leading to the identification of 14 genes associated with TNM staging. Over-expression of matrix gla protein (MGP) was confirmed in gastric cancer cell lines and tumor tissues by quantitative RT-PCR, Western blot and immunohistochemistry. Increased MGP expression was found in 22 of 54 cases of (40.7%) gastric cancer specimens compared to the normal gastric tissues. The up-regulation of MGP mRNA expression closely correlated with TNM stage (P = 0.001) and prognosis (P = 0.006).

CONCLUSIONSPublic databases of microarray studies are the valuable resources for data mining. MGP has been identified and confirmed as a novel biomarker for the TNM stage and prognosis of gastric cancer.

OBJECTIVETo summarize the experience of combined off-pump coronary artery bypass grafting (OPCAB) and pulmonary resection.

METHODSSeven patients with unstable angina or a history of myocardial infarction and pulmonary disease underwent combined OPCAB and pulmonary resection. All of them underwent coronary angiography, and neither coronary angioplasty nor stenting was feasible. OPCAB preceded the lung resections. The preferred approach to the heart and lung was by sternotomy. Left upper lobectomy was performed in 2 patients, right upper lobectomy was performed in 1 patient, right lower lobectomy was performed in 1 patient, right upper and middle bilobectomy was performed in 1 patient, left lung volume reduction surgery (LVRS) was performed in 1 patient and bilateral LVRS was performed in 1 patient.

RESULTSThere were no hospital mortality in this group of patients, however there were one late death. Sternal dehiscence occurred in 1 patient which was observed with a need for re-sternotomy and atrial fibrillation was observed in 1 patient. Five patients were diagnosed as malignant tumor by pathology test, and 2 patients were severe chronic obstructive pulmonary disease (COPD). Follow-up ranging from 2 months to 31 months was available for these patients. None of the patients showed evidence of myocardial ischemia after surgery. In one patient, who underwent right upper and middle bilobectomy, local recurrence was found at 19 months after surgery.

CONCLUSIONSOPCAB carried out simultaneously with lung resection is a safe and effective approach in patients diagnosed with concomitant coronary artery and pulmonary disease. OPCAB may decrease the incidence of postoperative complications.

BACKGROUNDCompared to the Western countries, Chinese patients present a special primary disease spectrum, diverse valvular pathogenesis, and different postoperational anticoagulation strategy. This research aimed to evaluate the mid- to long-term clinical performance of Hancock II bioprosthesis in the Chinese population.

METHODSThis study retrospectively reviewed all patients who received surgical treatments with at least one Hancock II bioprosthesis implantation from January 2004 to December 2013 at a single center in China. Totally 647 patients were included in the clinical evaluation, and 629 patients were successfully discharge, among whom 605 patients were completely followed-up. The follow-up rate was 96.2%. The mean and median follow-up time was 62.0 ± 59.0 and 56.0 months, respectively. Postoperative outcomes of survival rates, reoperations and valve related morbidities were assessed. Continuous and categorical variables were compared using the t -test and Chi-square test, respectively. Survival and freedom from adverse events were calculated by using a Kaplan-Meier method.

RESULTSThe overall in-hospital mortality was 2.8% (18/647) while there were 34 deaths (5.6%, 34/605) in the follow-up stage after discharge. The overall survival rate was 94.6% and 82.7% at 5 years and 10 years, respectively. The cumulative survival rate of 10 years was 82.8% in AVR group, 84.4% in MVR group, and 78.4% in DVR group. The overall rate of freedom from reoperations was 95.5% at 5 years and 86.8% at 10 years. The freedom from reoperation at 10 years was 87.0%, 88.1%, and 84.0% in AVR, MVR, and DVR group, respectively. The freedom from morbidities at 10 years was: 90.3% for thromboembolism, 95.2% for hemorrhage, 97.5% for prosthesis endocarditis, 95.9% for paravalvular leak, and 94.6% for structural valve deterioration, respectively.

CONCLUSIONSHancock II bioprosthesis exhibited a satisfactory mid- to long-term durability and promising clinical performance in the Chinese population. The occurrence rates of death and other adverse events in this single-center study were overall coincident and quite acceptable when compared with existing data.

UNLABELLEDTo reduce the huge labor-cost in the screening in traditional monoclonal antibody generation, We established a new system for monoclonal antibody generation integrating with protein array. BALB/c mice were immunized by eight recombinant proteins respectively, and the positive hybridoma cells were obtained by cell fusion and ELISA screening. All the eight kinds of positive hybridoma cells were mixed, cloned, screened by protein array, and definite dilution cloned.

RESULTS175 single cell clones were obtained by complex cloning, and 119 of those were positive clones. Then 8 positive cell lines were generated by the following 2 rounds definite dilution cloning. By comparing with the traditional method, we got 8 monoclonal antibodies using the combined protein array screening and multiplex cloning method in 1 cycle, and fewer amounts of antigens were used. As a result, the combined protein array and multiplex cloning method could be used as an economical, rapid and simple tool applying in high throughput monoclonal antibody generation.

OBJECTIVETyping of Mycobacterium tuberculosis strains and epidemiological studies in the army of southern China to provide scientific basis for prevention of pulmonary tuberculosis.

METHODSA rapid fingerprinting of M. tuberculosis strains method by polymerase chain reaction (PCR) with outward-directed primers that designed to the ends of the insertion sequence IS6110 was developed, and to analyze the relationship between the polymorphism of DNA fingerprinting and epidemiology of M. tuberculosis.

RESULTSOne hundred and fifty-four M. tuberculosis detected were classified into eight types according to their characters of PCR amplified fingerprints. The main types were type I (36.4%), type II (31.8%), and type III (21.4%), while other types were less than 4 percentage. In those main type groups, patients aged 20 to 29 and 30 to 39 took up 31.8% and 27.9% respectively. For those main types, the distribution of those types in the first treated patients showed significant difference compared with that in the retreated patients, and the rate of drug-resistance was also statistically different. However, the distribution was not statistically significant to history of BCG vaccination and patients living in urban or rural area. The main drug-resistant strains were only Isoniazid-resistant or Rifampin-resistant strains, while the drug-resistant strains were 44.4%, 29.6% and 14.8% respectively in type I, type II and type III.

CONCLUSIONPCR fingerprinting was a rapid, precise, sensitive, specific method to type M. tuberculosis, and could be used to study the epidemiology of tuberculosis; The prevalence of tuberculosis was primarily due to the transmission of type I, type II and type III in the army being studied from Southern China, to suggest that surveillance needs to be strengthened.
