Objective To investigate the safety and efficacy of transvaginal hydrolaparoscopic pelvic adhesiolysis (THLPA) treatment in the infertile women.Methods From May 2007 to Sep.2008,30 infertile patients underwent THLPA.The dye-test,hysteroscopy,and dye-test using catheterization of tubal ostium by hysteroscopy were performed at the same time.Pelvic adhesions were scored according to the revised American Fertility Society classification of endometriosis (1985).The adhesions were graded as mild (score 1-9),moderate (10-19),and severe (≥20).Twenty-four cases were in mild adhesions,5 moderate adhesions,and 1 severe adhesion.The duration of the operation and discharge,pelvic adhesions score,tubal patency,complications,and pregnancy rate were investigated.Results (1) THPLA:the majority of pelvic adhesions in all patients were successfully performed adhesiolysis.Only a little filmy adhesions of proximal peritube of 7 tubes and proper ligament of 5 ovaries and cohesive adhesions of 4 ovaries did not underwent surgical lysis.(2) Tubal patency:35 tubes were of proximal occlusion by dye-test,of which 21 (60%,21/35) were unobstructed and 4 (11%,4/35) were partly unobstructed after the dye-test using catheterization of the tubal ostium by hysteroscopy.(3) The duration of operation:the overall operative time were (32±6) minutes in mild adhesion,(52± 6) minutes in moderate adhesion,and 83 minutes in severe adhesion.Of which the time of THLPA were (11±5) minutes in mild adhesion,(35±7)minutes in moderate adhesion,and 62 minutes in severe adhesion,respectively.(4)The duration of discharge:the postoperative discharge time was 120-175 minutes.No complications occurred.(5)The rate of pregnancy:in the (15.8±4.3) months' follow-up,the rate of pregnancy was 45% (13/29),which one patient lost follow-up.Conclusions THLPA is safe,efficacious and not being hospitalized management.When compared with laparoscopy,it is simpler,more economic,and less minimally invasive approach.The appropriate indication of THLPA is to treat filmy,especially mild pelvic adhesions.It could partly avoid transabdominal operative laparoscopy for the infertile women.

The severity of coronary artery diseases is assessed based on morphological and functional stenosis.The study Oil detection of coronary artery diseases based on morphological lesions has unveiled its short comings for evaluation of the seriousness of the disease.Therefore,many research groups diagnose the coronary artery diseases by functional stenosis.From functional aspect,studies of x-ray angiography algorithms for blood flow and velocity measurement are potentially clinically important and are an actively researched subject,which Can accurately diagnose the coronary diseases from functional stenosis aspect.Based on the angiographic images,the article describes formulation and characteristics of existing coronary blood flow and velocity techniques such as tracking and computational methods.Tracking methods can be divided into four classes:bolus transport time algorithms,continuous velocity determination from two-dimensional(time-distance)parametric images,contrast traversal distance algorithms,and droplet tracking algorithms.Computational methods can be divided into six classes:indicator-dilution or Stewart-Hamilton method,first-pass distribution analysis,inverted continuity equation algorithms,inverse mass transport problem approach,optical flow type algorithms,and the fluid continuity method.

Objective To study the expression changes and patterns of nucleic acid and their derivative metabolism,processing and transport-related genes in rat liver regeneration(LR) at transcriptional level. Methods The related genes were obtained by online data collection and literature review,and gene expression patterns in rat regenerated liver were checked by Rat Genome 230 2.0 array.LR-related genes were identified through the comparison of discrepancles in gene expression between partial hepatectomy(PH) and sham operation(SO) groups. Results 240 genes were determined to be related with liver regeneration.The number of initially expressive genes in the forepart of liver regeneration(0.5-4 hours after PH),prophase(6-12 hours after PH),metaphase(16-66 hours after PH),anaphase(72-168 hours after PH) were 65,14,150,11 respectively and the total expression numbers were 133,87,627,169 respeitirely.There were 6,5,22 and 9 expression patterns.Frequencies of up-regulation and down-regulation were 768 and 248.mRNA catabolism in prophase and metaphase,DNA recombination,modification and transcript,mRNA processing and transport in prophase,metaphase and anaphase,and nucleotides and their derivatives metabolism,as well as DNA replication,packaging and catabolism during the whole LR,were enhanced.Conclusion LR-related genes were mainly triggered in the forepart of liver regeneration,and funclioned at different phases.

Objective To explore the clinical effect of hysteroscopic eletrosurgery for abnormal uterine bleeding of endometrial polyps.Methods 126 patients with abnormal uterine bleeding of endometrial polyps were selected,and they were selected and randomly divided into control group and research group according to the digital table,63 cases in each group.The control group received traditional curettage surgery, the research group received hysteroscopic eletrosurgery.The intraoperative blood loss,operative time,length of hospital stay,postoperative menstruation recovery time,therapeutic effect and complications were compared between the two groups.Results The intraoperative blood loss and operation time of the research group were significantly lower than those of the control group (t1=7.44,P1<0.01,t2=7.78,P2<0.01).And there were no statistical differences between the two groups in length of hospital stay and postoperative menstruation recovery time(t1=1.82,P1=0.07,t2=1.71,P2=0.09).The total cure rate of the research group was 100.00%,which of the control group was 92.14%,the difference was statistically significant(x2=8.18,P=0.00).The incidence rate of complications of the research group was 3.17%, which of the control group was 17.50%,the difference was statistically significant(x2=11.08,P=0.00).Conclusion Hysteroscopic eletrosurgery for abnormal uterine bleeding of endometrial polyps has remarkable clinical effects and low incidence of complications,and it is worthy of clinical application.

In new era,field medical equipment gives full scope to the development of medical equipment and fulfillment of daily operation.Meanwhile,to meet the requirements of military reform,basic sanitation service needs to grasp characteristics of medical equipment and to improve management capability of medical equipment.

By using antr-ras P21 mouse monoclonal (MoAb), SCI-Oncogema 1, the authors examined immunohistochemica! staining in pancreatc adeocarcinoma. The percentage of positive staining was 24/43 (558%). Furthermore it was indicated that the positive staining rate of antr-ras P21 MoAb was related to either histopathological grade or clinical stage. Upon statistical analysis of the correlation between the staining of anti-ras P21 and patient prognosis with Kaplan-Meier curve and Log-rant test, the positive staining cases showed comparatively better prognosis than the negative ones. Our study suggests that ras P21 expression may be important in the early stage of pancreatic carcinoma.

Objective: To observe the therapeutic effect of nicorandil on microvascular angina pectoris (MAP). Methods: A total of 60 MAP patients were randomly divided into nicorandil group (n=30) and routine treatment group (n=30), and they were treated for 12 weeks. Onset times and duration of angina pectoris, changes of related parameters of ECG treadmill exercise test before and after treatment, and total effective rate were compared between two groups. Results: Compared with before treatment, there were significant reductions in onset times and duration of angina pectoris and maximum depression extent of ST segment (P<0.05 or <0.01) and significant increase in total exercise time (P<0.01) after treatment in both groups; compared with routine treatment group, there were significant reductions in onset times of angina pectoris [(10.3±1.6) times/week vs. (9.6±1.7) times/week] and maximum depression of ST segment [(0.8±0.3)mm vs. (0.6±0.2)mm], and significant increase in total exercise time [(7.8±1.4) min vs. (9.4±1.6) min] and total effective rate (73.3% vs. 93.3%) in nicorandil group, P<0.05 or <0.01. Conclusion: Nicorandil possesses significant therapeutic effect on microvascular angina pectoris, and it is worth further study.
