Objective]The main summary of academic thought of Professor Qu Nini in treating chronic obstructive pulmonary disease. [Method]Through reading the tutor on chronic obstructive pulmonary disease works and clinically following up study, summarize the tutor in the treatment of chronic obstructive pulmonary disease, and through medical records. [Result]Professor Qu thinks that the lung, spleen and kidney three organs weakness, phlegm and blood stasis resistance are the main pathogenesis of this disease, in the treatment of tonic dispel, often with Bufei decoction, Suzi Jiangqi decoction as the basic decoction treatment, at the same time, more with the treatment based on syndrome differentiation, Yang phlegm, real tonic diarrhea. As a case, the effect is better. [Conclusion]Mentor in treatment of this disease, to pay attention to viscera weakness, also remove reality, internal and external treatment, reduce the acute exacerbation of chronic obstructive pulmonary disease frequency, improve the patient's symptoms, improve the quality of life of patients, is worthy of our generations to inherit and carry forward.

Objective To align the mapping points from the locations of catheter electrodes with CT/MR image three-dimension data of the cardiac chamber. Methods Most of existing algorithms assumed that two spaces spanned respectively by mapping points and by CT/MR data were orthogonal, and thus modulated only 9 free-degrees of three-dimension translations, rotations and scaling for registration. However, our research showed that the above two spaces might be not always orthogonal. So we introduced affine transformation model based on 12 free-degrees and the corresponding iterative closest point algorithm to realize the registration and further incorporate the registration algorithm with the clinical operations. Combining with OpenGL, we realized the proposed algorithm via Visual C]+]+ 6.0 software. Results Simulation results showed that the residual registration errors on average were decreased from 40 pixels before registration to 1.5 pixels after registration. This algorithm was further validated in animal experiments. Conclusion This proposed three-dimension mapping registration algorithm well realizes the registration in three-dimension cardiac mapping and has practical application values.

The imaging of X-ray, CT and MRI of 25 cases of limb bone contusion were analyzed retrospectively. Twenty five cases of limb bone confusion were diagnosed by MRI imaging, including 18 cases(72% ) in knee joint,4 cases(16%) in anklebone,2 cases(8%) in wrist and 1 case(4%) in elbow joint. But only 3 cases (12%)presented partial positive results in CT imaging and there was no bone contusion diagnosed. No abnormal manifestation in X-ray imaging for all 25 cases. The results suggest that MRI examination is valuable for diagnose of limb bone contusion.

Imaging examination results of 50 breast cancer patients undergoing surgical treatment between January 2006 and December 2007 were retrospectively analyzed. Our data showed that 32 patients (64%) had positive results in contrast-enhanced CT, and metastases to lung, mediastinal lymph node, axillary lymph node, or chest wall were found in 22 (44.0%), 11 (22.0%), 10 (20.0%), and 3 patients (6.0% ), respectively. Only 10 patients (20%) had abnormal image manifestation in X-ray, 8 of which showed metastases to lung. In summary, contrast-enhanced CT examinations may be more useful in the detection of metastases in post-operative follow up of breast cancer.

The paper proposed a concept to build a management system for operating room hidden costs in an effort to better hospital management and alleviate patients' economic burden.The authors analyzed the root of such costs from the levels of operating room's design and construction,as well as management and operations,proposing a framework of such hidden costs.Based on diversified cost characteristics,they come up with a number of estimating methods,and control methods against different hidden costs by using management theories systematically.

OBJECTIVE:To provide reference for the clinical rational application and preventing the adverse reactions of hy-droxyethyl starch(HES). METHODS:The HES application of inpatients in a hospital in Jul. 2014 were retrospectively analyzed, the usage and dosage,indications,and the changes of renal functions and blood coagulation function before and after HES treat-ment were detected,and the application rationality was evaluated. RESULTS:The usage of HES in the hospital was hydroxyethyl starch 200/0.5 and Sodium chloride injection,which was the second generation of HES. In the 347 patients,295 patients had moni-tored the renal functions before the HES treatment,the result was normal;and 21 patients had monitored the renal functions after HES treatment,the result was normal. Meanwhile,326 patients had monitored the blood coagulation functions before and after HES treatment,the results were normal. HES was not used for the patient of severe sepsis,renal dysfunctions and coagulopathy in this hospital. CONCLUSIONS:The application of HES can induce renal damage and coagulation disorder,so relevant indicators should be closely monitored before and after treatment to prevent the incidence of adverse reactions;further more,clinicians should strictly handle indications,usage and dosage and precautions during the clinical application;in addition,it is suggested to replace the second generation of HES by the third generation,which is more safer.

Introduction: Adolescents below the age of majority require parental consent for treatment or else the treating doctor may be liable for trespass and assault. This creates a dilemma for frontline doctors, as involving parents in the discussion could add yet another barrier to the existing barriers for adolescents in terms of access to healthcare services.

Currently,medical ethics education is well popularized,yet not popular among medical students,interns or clinical doctors,for which its formalistic teaching content and mode are to blame.To realize its real educative effects,infiltrating medical ethics into the ideological perception among medical students,interns and clinical doctors,besides horizontal expansion in education popularity,more emphasis should be put to grasping and instructing the essence of medical ethics on a vertical level in order to make the recognition of medical ethics education as common sense among medical professionals.

Objective To investigate the clinical value of serum tumor makers CA15-3,19 fragments of cellular keratin antigen(CYFRA21-1)combined with the color Doppler ultrasound and mammography X-ray in diagnosis of early breast cancer.Methods According to the postoperative pathologic diagnosis,collected 106 cases of patients with breast cancer (breast cancer group) and 50 cases of patients with benign breast lesions (control group),the serum tumor makers CA15-3,CYFRA21-1,the color Doppler ultrasound and mammography X-ray were compared with postoperative pathology and statistical analyzed retrospectively.Results The sensitivity of CA15-3 was 63.2%(67/106),specificity was 94.O% (47/50);the sensitivity of CYFRA21-1 was 73.6%(78/106),specificity was 88.0%(44/50);the sensitivity of color Doppler ultrasound was 77.4%(82/106),specificity was 90.0%(45/50);the sensitivity of mammography X-ray was 75.5%(80/106),specificity was 92.0%(46/50);the sensitivity of the four combined detections was 96.2%(102/106),specificity was 80.0%(40/50).The sensitivity of combined detection was higher than any of them individually,there was statistical significance (P<0.05).Conclusions Combined diagnosis is an effective way of early breast cancer detection.It has high positive rate of diagnosis and reliable guidance significance for diagnosis and treatment.

BACKGROUND:Injection of isoproterenol is known to induce proliferation and hypertrophy of acinar cells in rodent salivary glands. However, the clonal proliferation ability of stem/progenitor cells of salivary glands by isoproterenol remains unclear.
OBJECTIVE:To study the proliferation and activation ability of stem/progenitor cells of submandibular gland with colony assay by intraperitoneal injection of isoproterenol.
METHODS:Sprague-Dawley rats were randomly divided into two groups, isoproterenol and control groups, respectively intraperitonal y injected with isoproterenol and normal saline for 5 consecutive days. The gland tissues were harvested, and the stem/progenitor cells of submandibular gland were obtained by enzyme digestion in vitro. The number of clonal colonies of each group was analyzed. The larger colony cells were col ected for immunohistochemistry staining with CD90.1, laminin andα6β1.
RESULTS AND CONCLUSION:The number of middle and low proliferative potential colony-forming cells was less but high proliferative potential colony forming cells were significantly more in isoproterenol group compared with control group (P<0.05). However, there was no significant difference in the total number of the colonies between two groups (P>0.05). The high proliferative potential colony forming cells were positive for CD90.1, laminin andα6β1. Results showed that isoproterenol treatment model cannot increase the cellnumber, but enhance the proliferation ability of stem/progenitor cells from the submandibular gland.
