Objective To compare the results of conservative treatment operation for two groups of tubal pregnancy with laparoscopy and laparotomy. Methods We disparted tubal pregnancy patients into two groups: laparoscopy group(418 cases from August 2001 to December 2004) and laparotomy group(182 cases from January 1998 to July 2001) ,and evaluated the clinical characteristics,the postoperative incidences of persistent ectopic pregnancy, the rate of intra-uterine pregnancy and the rate of ectopic pregnancy. Results In the laparoscopy group,only 1 case arised the postoperative incidences of persistent ectopic pregnancy. In the laparotomy group,6(3. 3% ) out of 182 arised(P 0. 05). Conclusion Laparoscopy has advantage over laparotomy therapy in the conservative operation of tubal pregnancy.

Objective To investigate the expressions and effects of EGR-1, p53, p16, Cyclin D1 in Nasopharyngeal Carcinoma (NPC). Methods Expressions of EGR-1, p53, p16, and Cyclin D1 protein in paraffin-embedded specimens of 29 chronic nasopharyngitis, 45 NPC and 24 lymph-node metastasis were studied by immunohistochemical method (SABC). Results The positive rates of EGR-1, p16, and Cyclin D1 protein expressions in chronic nasopharyngitis were 44.83 %(13/29), 89.66 %(26/29) and 24.14 %(7/29) respectively, but no p53 protein expression. In NPC, the positive expression rates of the four proteins were 22.22 %(10/45), 91.11 %(41/45), 53.33 %(24/45) and 66.67 %(30/45), with significant difference compared with chronic nasopharyngitis respectively; and in lymph nodes metastasis were 16.67 %(4/24), 79.17 %(19/24), 70.83 %(17/24) and 75.00 %(18/24) with significant difference compared with those of chronic nasopharyngitis and NPC respectively except for p16 protein. Spearman correlation analysis showed that there were no significant correlation between the expression of EGR-1 and p53, p16, Cyclin D1 respectively both in NPC and in lymph nodes metastasis. In NPC, the expression of p53 showed a positive correlation with the expression of p16; and in lymph nodes metastasis the expression of Cyclin D1 showed positive correlation with the expressions of p16 and p53. Conclusions The expression of EGR-1 protein was significantly decreased both in NPC and in lymph-node metastasis, which suggested that Egr-1 gene may be a tumor suppressor gene and have an important effect in the pathogenesis and the progression of NPC. The overexpression of p53 and Cyclin D1 also have an important role in NPC, but p16 probably have no biological significance in NPC.

Objective To finding out the characters of vascular remolding after the establishment of native arteriovenous fistula on the wrist,and exploring the influential factors.Methods Doppler ultrasound was used to monitor the diameter of cephalic vein,brachial artery,radial artery and ulnar artery at the time before the surgery and one day,one week,two weeks,four weeks and eight weeks after the surgery respectively.The tendency of the diameter change was analyzed.Results Twenty eight patients completed the whole monitor session,in which eleven were female.The average age of those patients was (53.68 ± 2.61) years old.Twelve of them were diabetic nephropathy.The diameters of all vessel were increased more rapidly at the first day than any other days after surgery(all P ＜ 0.01).The patients were divided into two groups depending on whether diabetic nephropathy.No significant difference was found between the two groups on the tendency of diameter change in cephalic vein and brachial artery (all P ＞ 0.05).However,the tendency of diameter change in radial artery and ulnar artery was statistically significant difference between the two groups (all P ＜ 0.05).Conclusions Cephalic vein,brachial artery,radial artery and ulnar artery are all apparently dilated on the first day after the surgery.The vascular dilation and diameter increasing become much slower after the period,the diameter tend to be stable.The primary diseases may affect the tendency of the diameter change in radial artery as well as ulnar artery.

Objective: To study the absorption and utilization of dietary iron, zinc and calcium of male adults of Yi nationality, for basic information to prevent and cure diseases related to mineral deficiencies. Method: Twelve young men aged between 20 and 22 from the region lived by Yi nationality were studied in 14 d period with metabolic balance technique. At the beginning of study, their fasting blood hemoglobin and hematocrit, serum ferritin, plasma zinc and calcium concentration were deteimined. During the 4-12 d of the study, experimental diet, subsequent feces and urine samples were also collected for determining the contents of iron, zinc and calcium by flame atom absorption spectrum method, and then apparent absorption rate, apparent utilization rate and metabolic balance of these minerals were calculated. Results: The apparent absorption rate of iron, zinc and calcium was (15.8?6.2)%, (24.5?4.1)% and (32.3?9.7) % and the apparent utilization rate was (1.9?5.7)%, (12.8?4.3)% and (5.5?15.9)% respectively. The metabolic study showed iron balance, and zinc balance, but calcium balance was variable. Conclusion: The intakes of iron and zinc from the diet can meet the requirements, but calcium cannot. More intakes of foods rich in calcium are recommended for Yi nationality.

Object To investigate the maturity status of the cephalic vein when the native arteriovenous fistula matures and set up indicators of a matured native arteriovenous fistula.Methods The diameter,flow rate and wall thickness of the cephalic vein were prospectively measured by Doppler ultrasound after the native fistula was created.Mature judgment was done by skilled nurses depending on their experience before the fistula was punctured.The ultrasound data was marked as proposed mature at the same time.After three times dialysis,if blood flow was fluent and complications such as prolonged bleeding time and hematoma were absent,fistula mature was confirmed.Results Thirty-one patients were admitted to the study,then fistula were matured.The average age of those patients was (52.93±3.21) years old.Thirteen patients were female.Twenty two fistula located on the left arm.Thirteen of the patients were diabetic nephropathy.The average diameter of cephalic vein was increased from (3.10±0.11) mm before surgery to (4.74±0.16) mm when the fistula was matured,though it was still smaller than 6 mm which K/DOQI guideline had recommended (P ＜ 0.05).The average mature period was (57.10±3.21) days.The matured fistula had an average high flow rate of (569.76±48.34) ml/min and wall thickness of (0.95±0.04) mm.The one-side 95％ credibility interval of the diameter,flow rate and wall thickness of cephalic vein was 4.44 mm,486.37 ml/min and 0.67 mm,respectively.Conclusions The diameter of cephalic vein in a matured native arteriovenous fistula in our study was significantly smaller than 6 mm which K/DOQI guideline had recommended.The indicators of native arteriovenous fistula mature in our country may different from abroad.

BACKGROUND:Poultry mesenchymal stem cels are a particular subset of pluripotent adult stem cels derived from the mesoderm, which have great application prospects because of their strong proliferation and multi-directional differentiation potential. OBJECTIVE:To review the source, separation, purification, culture and differentiation of poultry mesenchymal stem cels, and to provide the theoretical foundation and experimental basis for the further research and application of poultry mesenchymal stem cels. METHODS:PubMed and CNKI databases were searched by the first author using key words of “mesenchymal stem cels, poultry, chicken, isolation, culture, differentiation” in English and in Chinese, respectively, to retrieve relevant articles published from 1990 to 2014. Literatures addressing induced poultry mesenchymal stem cels were included, and 42 articles were chosen for further analysis eventualy. RESULTS AND CONCLUSION: Poultry mesenchymal stem cels have great application prospects in the aspects of establishingin vitro model of poultry cels, studying poultry disease pathogenesis, animal nutrition and meat quality control. Its origin source is wide and easy to obtain. Isolation, purification, culture and biological characteristics of mesenchymal stem cels from different tissues are different. But, the study on poultry mesenchymal stem cels is stil in the exploration process, and there are many technical problems to be solved.

Objective:To investigate the efficacy and safety of peritoneal dialysis (PD) in end-stage renal disease (ESRD) patients with liver cirrhosis (LC).Methods:Clinical data of PD patients receiving regular treatment followed up for≥6 months, and aged≥18 years in the Third Affiliated Hospital of Hebei Medical University Peritoneal Dialysis Center from January 1, 2013 to March 31, 2020 were retrospectively collected. The patients were divided into LC-PD group and non-LC-PD group according to whether they had LC or not. Propensity score matching (PSM) was used to match the LC-PD group and the non-LC-PD group with 1∶4 ratio. The baseline clinical data, dialysis adequacy, peritonitis and clinical outcomes between the two groups were compared. Kaplan-Meier survival curve and Log-rank test were used to compare the survival rate and technical survival rate between the two groups.Results:A total of 241 PD patients were included in this study. After PSM, 13 cases in LC-PD group and 52 cases in non-LC-PD group were included. Compared with non-LC-PD group, patients in LC-PD group had lower baseline urine volume ( Z=-3.546, P<0.001) and serum albumin ( Z=-2.609, P=0.009). At the follow-up of 3, 6, 12 and 24 months, total serum protein ( t=-3.319, P=0.002), serum albumin ( t=-4.019, P<0.001), triglyceride ( Z=-2.263, P=0.024), and serum phosphorus ( Z=-2.173, P=0.030) in the LC-PD group were lower than those in non-LC-PD group. During the follow-up period of 2 years, the patients in the LC-PD group had significantly higher serum albumin than baseline values ( χ2=16.901, P=0.001), and there was no statistically significant difference between the two groups ( χ2=0.155, P=0.694). The decline rate of residual kidney Kt/V in the LC-PD group was slower than that in the non-LC-PD group ( χ2=44.589, P<0.001). The incidence of peritonitis in LC-PD group was higher than that in the non-LC-PD group, with a statistically significant difference (0.59/patient-year vs 0.20/patient-year, Z=-2.135, P=0.033). The composition ratio of pathogenic bacteria in both groups was mainly gram-positive bacteria (10/25 vs 11/30) and proportion of Streptococcus in LC-PD group was higher than that in non-LC-PD group (4/10 vs 0/11, P=0.035). The proportion of Escherichia coli in the first peritonitis was higher than that in LC-PD group (4/9 vs 1/22, P=0.017). The Kaplan-Meier survival curve results showed no statistically significant difference in survival rate (Log-rank χ2=0.491, P=0.484) and technical survival rate (Log-rank χ2=0.408, P=0.523) between the two groups. Conclusions:PD is a safe and effective treatment mode for ESRD patients with LC, and the survival rate and technical survival rate are comparable to those patients without LC. The incidence of peritonitis in patients with LC-PD in our dialysis center is higher than that in the non-LC-PD patients, and gram-positive bacterial infections are the mainstay, suggesting that attention should be paid to strengthening patient management and training.

The current paper will focus on the characterization, diagnosis and treatment of pathogenic bacteria in bronchiectasis.

ObjectiveTo study the clinical efficacy of dapagliflozin combined with Shexiang Baoxinwan （SXBXW） in the treatment of acute heart failure with reduced ejection fraction （HFrEF） and syndrome of Qi deficiency and blood stasis. MethodA total of 176 patients hospitalized due to acute HFrEF （syndrome of Qi deficiency and blood stasis） were selected and randomized into control group， SXBXW group， dapagliflozin group， and SXBXW + dapagliflozin group （the latter three groups were called the intervention groups）. The New York Heart Association （NYHA） class， 6-minute walk test （6MWT） score， Kansas City Cardiomyopathy Questionnaire （KCCQ） score， traditional Chinese medicine （TCM） syndrome score， N-terminal pro-brain natriuretic peptide （NT-proBNP）， soluble suppression of tumorigenicity 2 （sST2）， interleukin-6 （IL-6）， and hypersensitive C-reactive protein （hs-CRP） of the patients were evaluated and measured at the time of admission， 1 week after treatment， and 2 weeks of treatment. Furthermore， the hospital stay， in-hospital mortality， and 30-day re-admission rate were recorded. Statistical analysis was performed to evaluate the efficacy of each group. ResultAfter 1 week of treatment， the SXBXW group exhibited superior NYHA class， KCCQ score， TCM syndrome score and curative effect， IL-6， and hs-CRP to the control group （P<0.05， P<0.01）. After 2 weeks of treatment， the SXBXW group showed superior TCM syndrome score， TCM curative effect， and hs-CRP （P<0.05， P<0.01） to the control group. The dapagliflozin group was superior to the control group in terms of TCM syndrome score， NT-proBNP， and sST2 （P<0.05， P<0.01） after 1 week of treatment and in terms of NYHA class， KCCQ score， NT-proBNP， sST2， and hospital stay （P<0.05， P<0.01） after 2 weeks of treatment. The SXBXW + dapagliflozin group exhibited better efficacy than the control group in terms of NYHA class， 6MWT score， KCCQ score， TCM syndrome score and curative effect， NT-proBNP， sST2， IL-6， and hs-CRP （P=0.014） after 1 week of treatment and in terms of NYHA class， KCCQ score， TCM syndrome score and curative effect， NT-proBNP， sST2， IL-6， hs-CRP， and hospital stay （P<0.01） after 2 weeks of treatment. ConclusionSXBXW and dapagliflozin have good therapeutic effect on acute HFrEF and syndrome of Qi deficiency and blood stasis， and their combination demonstrated better therapeutic effect， with good safety and tolerability.
