Objective To analyze the clinical features and interval of multiple primary carcinoma (MPC). Methods 52 patients with MPCs between October 2002 and May 2007 were reviewed. Results 7 patients had synchronous carcinoma (13.46%), and 45 had metachronous carcinoma (86.54%). The interval between the first primary cancer and MPC was from 0 to 31 years, averaged 7.1 years. Male was 7.3 years, and female was 9.3 years (P

Under the socialist market-oriented economic system, state-owned hospitals need to overcome many problems in their traditional management system. The authors discuss a series of issues, including the property right involved in the reform of the management system of state-owned hospitals; the relationships between nonprofit hospitals run by the government and ways of handling them; the conditions of using the corporation management structure in hospitals; the responsibilities of the government in the framework of medical services and the form in which the government supervises state-owned hospitals. Lastly, the authors put forward suggestions from the perspective of policy-making on the reform of the management system of state-owned hospitals.

[Objective] The aim was to choose the best feeder layer by observing the effects of various human feeders supporting human embryonic stem cells (hESCs), and to probe the correlation between the levels of basic fibroblast growth factor (bFGF) secreted by feeders and the growth of the hESCs. [Methods] The primary cells from various tissues were cultured, including foreskin, stromal endometrium, villus, adult fallopian tubal, fetal skin, fetal muscle and mouse embryonic fibroblasts (MEFs). The hESCs were transferred to various feeders, and then the best condition was probed, which was based on the feeder density and the time of mitomycin-C acting on the feeder. Comparing the characteristics of the hESCs, the best feeder was chosen of all kinds of feeders from various tissues that support the hESCs. The level of bFGF secreted by various feeders was detected using ELISA. [Results] All of tested feeders could support the hESCs growth for over 10 passages in the culture, especially the foreskin and the adult fallopian tubal. The density of feeders was related with the morphology and the differentiation rate of the hESCs. According to the characteristics of feeder, the feeder ranking was as follows: foreskin, stromal endometrium, villus, adult fallopian tubal, fetal skin and fetal muscle. Based on the characteristics of the hESCs, the order of feeders was: foreskin, adult fallopian tubal, stromal endometrium, villus, fetal muscle and fetal skin. The levels of bFGF (pg·10~(-5)·mL~(-1)) secreted by various feeders were as follows: adult fallopian tubal (13.23±3.39), foreskin (1.99±0.17), villus (1.40±0.17), fetal muscle (2.02 ±1.59), stromal endometrium (0.38±0.28), and fetal skin (0.29±0.29). [Conclusion] The foreskin and the adult fallopian tubal could support the hESCs better than others though all of them could;do, especially the, foreskin. The bFGF that secreted by the adult fallopian tubal was the highest of all. The correlation was not obvious .between the levels of bFGF secreted by feeders and the growth of the hESCs.

Objective To analyse the clinical characteristics,gene mutation and enzymatic activity of αgalactosidase A(α-GalA)in a 15-year-old male patient with typical Fabry disease,whose mother was without any clinical manifestations.Methods Clinical features and laboratory data were collected from the patient and his mother.Genomie DNA was extracted from peripheral blood of the patient.his mother,and a healthy control subject.Seven exons of the GLA gene were amplified by PCR.PCR products were purified.cloned into T vector,and then sequenced.The enzymatic activity of α-GalA Was measured by fluorimetrie substrate assay. Results DNA sequencing results showed that a missense mutation of 10036-10038delAAG in exon 7 WaS identified in the patient,resulting in the replacement of 374 lysine and 375 glyeine by arginine,which Was not previously reported.The patient Was a hemizygote with gene mutation,his mother WaS a heterozygote carrying gene mutation,and the healthy control without mutation.α-GalA enzymatic activity assay showed that the enzymatic activity of the patient with GLA gene mutation was only 50%of the healthy control subject,while the enzymatic activity of the patient's mother Was about 70%of the heahhy control SObject.Conclusiolls Detecting GLA gene mutation and α-GalA enzymatic activity in patients with Fabry disease who have been clinically diagnosed seelns to be helpful in finding other patients in the family and in further understanding the molecular pathogenesis of that disease.

Objective:To extract DNA from Bifidobacteria and E.coli cells and incubate DNA with IEL to observe.DNA's activation for IEL.Also plan to use the DNA to immune mice to observe the change of immunologic function,discuss the effect of Bifidobacteria and E.coli's whole DNA to murine and make a comparision study.Methods: Mice of Bifidobacteria DNA and E.coli's DNA treated groups are respectively given with DNA by muscular and subcutaneous injection. Detect the immunologic function of spleen cell, extract IEL cells and incubate them with DNA, detecting IEL activity and the production of cytokine. Results:The activities of IL 2 and NK are all significantly higer than those of in control groups (P

Objective To raise the awareness of acute kidney injury (AKI) and improve the level of diagnosis.Methods All the hospitalized adult patients in the Affiliated People's Hospital of Shanxi Medical University from January 2012 to July 2013 were screened.Those patients diagnosed as AKI were retrospectively analyzed in terms of incidence,the rate of missed diagnosis,etiology,distribution and prognosis of AKI.Results (1) The incidence of AKI in the patients was 0.67％ (381/56 835),the ratio of male to female was 1.91 ∶ 1,and the average age was (63.45±16.95) years.(2)There were 321 cases diagnosed as pre-renal AKI (84.25％),42 cases diagnosed as renal AKI (11.02％) and 18 cases diagnosed as post-renal AKI (4.72％).(3)There were 189 cases(49.61％) missed diagnosed among all the screened cases.The rates of missed diagnosis in neurosurgery,general surgery and cardiac surgery department was 62.96％,59.09％ and 50.00％,in cardiology,respiratory and neurology department was 50.00％,50.00％ and 45.45％ respectively.(4) Multivariate Logistic regression analysis showed that hypertension [odds ratio(OR)=1.631],renal replacement therapy(RRT)(OR=23.256) and oliguria history (OR=1.936) were independent risk factors of missed AKI diagnosis.Conclusion The missed diagnosis rate of AKI is high and has certain characteristics in different departments.Hypertension,RRT and oliguria history are independent impact factors of missed AKI diagnosis.

Nuclear magnetic resonance (1H-NMR) fingerprint of Rhodiola rosea medicinal materials was established, and used to distinguish the quality of raw materials from different sources. Pulse sequence for water peak inhibition was employed to acquire 1H-NMR spectra with the temperature at 298 K and spectrometer frequency of 400.13 MHz. Through subsection integral method, the obtained NMR data was subjected to similarity analysis and principal component analysis (PCA). 10 batches raw materials of Rhodiola rosea from different origins were successfully distinguished by PCA. The statistical results indicated that rhodiola glucoside, butyl alcohol, maleic acid and alanine were the main differential ingredients. This method provides an auxiliary method of Chinese quality approach to evaluate the quality of Rhodiola crenulata without using natural reference substances.
