Objective: To establish a quantitative method for determination of protocatechuic acid in Xueniao Capsules. Methods: The capsules were extracted with alcohol acetic acid (10∶1) and then solved with absolute alcohol. The sample was applied on a silica H plate, developed and separated in the solution of chloroform acetone methanol acetic acid (7∶2∶1.5∶0.5). The separated spots were determined by TLC scanning at 530nm(? s). Results: The average recovery was 101.4%. Conclusion: This method for determination of protocatechuic acid in Xueniao Capsules was sensitive, accurate and specific. It could be used as quality control for Xueniao Capsules.

The hypo-morality,also known as sub-morality,is an imperfect morality compared with the social mainstream morality.By introducing some "hypo-morality" phenomena in the current physician-patient relationship and analyzing from the two aspects including the diversity of interests main bodies and the market operational mode of healthcare institutions,this paper assures the rationality of the existence of hypo-morality in physician-patient relationship,and attempts to provide feasible suggestions for a reasonable direction of hypo-morality in physician-patient relationship.

For 10 years recently,China has implemented the strategy of "rejuvenating technology,talents for the first",and China's higher education has made improvement significantly: the number of student in-class increases drastically,the gross enrollment rate of higher education reached the level of popular education.Kunming Medical College,in this particular historical period of development by accelerating the construction and structural adjustment, strengthening management,taping potential,integrating use of resources,has better dealt with the enormous pressure and the challenge caused by the school's operating scale's nearly five times increase,and has ensured the quality of student training;In the new historical period of development, Kunming Medical College will continuously change education ideas,achieve the leap development from teaching university to teaching and research university positively.

Objective:To investigate the clinical efficacy ofacupuncture plus Tuina therapy in treating supraspinatus tendinitis.Methods:One hundred patients with supraspinatus tendinitis were randomly allocated to two groups.The treatment group of 50 cases was treated with acupuncture plus Tuina therapy and the control group of 50 cases,with simple acupuncture.Treatment was given once daily,10 times as a course.The therapeutic effects were evaluated after two courses oftreatment.Results:The total efficacy rate was 96.0%in the treatment group and 74.0%in the control group.x2 test showed that there was a statistically significant difference in the total efficacy rate between the two groups(P＜0.01).Conclusion:Acupuncture plus Tuina therapy is superior to simple acupuncture in treating supraspinatus tendinitis.

The contrast of technical force between hospital and society is astonishing in the maintenance & service of large-scale medical equipment.When the maintenance & service plan must be chosen to socialized service,all the plans must be seriously compared and evaluated according to the current situation of the equipments in hospital for an economical and suitable selection.A right selection is necessary in promoting maintenance and management of large-scale medical equipment,keeping good operation of equipment,prolonging service life,and creating better economic and social benefits.

Platelet-derived growth factor (PDGF), a potent chemotactic and mitogenic factor, is involved in the regulation of hematopoiesis and platelet production. Our studies demonstrate the presence of functional PDGF receptors (PDGFR) on human megakaryocytes/platelets and CD34(+) cells, and their ability to mediate a mitogenic response. PDGF promotes the ex vivo expansion of human hematopoietic stem (CD34(+)) and progenitor (CD41(+)) cells. More significantly, PDGF enhances the engraftment of human CD45(+) cells and their myeloid subsets (CD33(+), CD14(+) cells) in NOD/SCID mice. PDGF also stimulates in vitro megakaryocytopoiesis via PDGFR and/or the indirect effect on bone marrow microenvironment to produce TPO and other cytokines. It also shows a direct stimulatory effect of PDGF on c-Fos, GATA-1 and NF-E2 expressions in megakaryocytes. We speculate that these transcription factors may be involved in the signal transduction of PDGF on the regulation of megakaryocytopoiesis. PDGF also enhances platelet recovery in mouse model with radiation-induced thrombocytopenia. This radioprotective effect is likely to be mediated via PDGFR with subsequent activation of the PI3K/Akt pathway. It provides a possible explanation that blockage of PDGFR may reduce thrombopoiesis and play a role in imatinib mesylate-induced thrombocytopenia.

Objective To study the efficacy of thyroidal arterial embolization in treating hyperthyroidism by using different embolizing materials and the relationship between recurrence rate and the numbers of embolized arteries. Methods 56 cases with hyperthyroidism were divided into group A (25 cases) and group B (31 cases). Patients of group A had their thyroidal arteries embolized with gelfoam particles and stainless coils after arterial infusion of a total dosage of 24 mg of blemycin. Patients of group B had their thyroidal arteries occluded with polyvinyl alcohol (PVA) particles. The effectiveness and general complications of arterial embolization for these two groups were compared and the relationship between recurrence rate of hyperthyroidism after treatment and numbers of embolized thyroidal arteries was studied. Results It showed effectiveness in all patients within 2 3 months. The follow up records showed, the recurrence rate of hyperthyroidism was 28% and 16.1% for group A and group B respectively but without statistical difference. The recurrence rates were 46.7% for those patients with 2 thyroid arteries embolized and 12.2% for those with 3 4 arteries embolized, showing significant difference ( ? 2=7.751, P

Objective To evaluate the value of serum tumor markers in diagnosis of over 80 years old patients with colorectal cancer.Methods Serum CA199,CA242 and CEA of 68 cases senile patients with colorectal cancer and 35 cases senile patients with benign large intestinal diseases were detected by ELISA.Results Serum levels of CA199,CA242 and CEA in patients with colorectal cancer were (37.95 ± 15.95 ) U/ml,( 50.08 ± 24.20 ) U/ml,( 22.34 ± 17.35 ) μg/L respectively and were significantly higher than that in patients with benign large intestinal diseases CA199 ( 10.73 ± 6.27 ) U/ml,CA242 ( 8.00 ± 3.52 ) U/ml,CEA(2.32 ± 1.01 )μg/L.In addition,the level of these three markers was increased with the progress of colorectal cancer and the sensitivity of diagnosis was related with the stages of colorectal cancer.Parallel combined testing methods increased the diagnostic sensitivity to 83.6％,and serial combined testing increased the diagnostic specificity to 88.7 ％.Conclusions Serum tumor markers showed certain values in the diagnosis of the senile patients with colorectal carcinoma.Furthermore,the combined determination of tumor markers is helpful for early diagnosis of colorectal cancer and increases the sensitivity and specificity in diagnosing of colorectal carcinoma.
