After-department examination palys an important role in clinical teaching.The level of clinical teaching is one of the most important markers to evaluate the whole quality of the hospital.To improve the ability of teaching and teaching concept,we summarized the problem of after-department examination and put forward a series of reformation methods.

Polycystic ovary syndrome (PCOS) is one of the most popular diseases in obstetrics and gynecology research at internal and abroad at present, traditional Chinese medicine(TCM)in the clinical treatment of the disease have the advantage. Clinical epidemiological study of descriptive research method this research adopts investigation, observation of TCM syndromes and improper diet through 401 cases in Jiangsu Province confirmed PCOS patients, to explore the relationship between TCM syndrome type distribution and improper diet factors, and to provide the clinical basis for further etiology of this disease research. TCM syndrome type distribution of the disease is kidney deficiency, phlegm stagnation syndrome, qi stagnation and blood stasis syndrome, syndrome of dampness heat of liver channel and is composed of 4 basic syndromes and formed complex syndrome, and the composite and syndrome type (60.85%); combined with the analysis of traditional Chinese medicine dialectical, Pure empirical syndrome this disease (46.88%), followed by the actual card (45.39%), pure deficiency is rare. Improper diet factors associated with the disease, in which improper diet with different TCM syndrome type distribution significantly related. Stagnation of phlegm dampness syndrome is the main syndrome of the disease type, improper diet factors and every syndrome PCOS type distribution is as follows: the partial eclipse fatness greasy with basic syndromes of phlegm dampness stagnation of kidney deficiency syndrome, the nephrasthenia syndrome is less; eating spicy stimulation by basic syndromes of stagnation of Qi and blood stasis; eating cold people the basic certificate type of qi stagnation and blood stasis; The diet of patients are more prone to stagnation of phlegm dampness syndrome.

Chemokines are major regulators of cell transformation and adhesion.Recent study has demonstrated that CXCR7 can bind to CXCL11 and CXCL12 with high affinity,and the activated CXCR7 may influence tumor invasion and metastasis by regulating extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) and other signal transduction pathways.Therefore,in-depth study of the molecular mechanisms of CXCR7 in tumor invasion and metastasis may provide a more effective theoretical basis for tumor treatment.

BACKGROUND: Observation and comparison about space-occupying lesions due to herniated nucleus pulposus, as well as nerve root compression in lumbosacral disc herniation and manipulative therapy are easily available; however, there is still lack of related quantitative research regarding the internal pressure in herniated nucleus pulposus.OBJECTIVE: To observe the influence of the internal pressure in herniated nucleus pulposus on nerve root compression in patients with lumbosacral disc herniation.DESIGN: Case control study.SETTING: Bone Setting Therapeutic Center, the Air Force General Hospital of Chinese PLA.PARTICIPANTS: Totally 30 patients with lumbosacral disc herniation received operation in the Orthopedic Department of the Air Force General Hospital between October 2002 and December 2003; meanwhile, 15 patients with lumbosacral disc herniation received manipulative therapy in the Bone Setting Therapeutic Center of the same hospital.ing positive group and negative group according to the results of straight leg raising test. The pressure in herniated nucleus pulposus was detected during operation, and the straight leg raising height was also recorded beThe size of intervertebral disk herniated nucleus was presented by the maximum vertical distance from the intervertebral disk herniating apex to the posterior edge of vertebra on CT and/or MRI transverse section.raising height.RESULTS:Totally 30 patients received operative treatment whereas 15The pressure in lumbosacral disc herniated nucleus andthe size of herniated nucleus pulposus: as for patients who received operation, the pressure in herniated nucleus pulposus was obviously higher in positive group than in negative group [(2.119±0.753), (0.483±0.420) kPa, P ＜ 0.01]. However,the size of herniated nucleus pulposus was not significantly different between positive group and negative group [(4.688±1.991), (4.857±2.033) mm,nipulative therapy, their straight leg raising height was obviously increased compared to that before operation [(54.000±16.388)°, (72.668±15.338)°,P ＜ 0.01], but the size of herniated nucleus pulposus was proved not obviously changed by CT or MRI examination after manipulative therapy (P ＞ 0.05).cleus pulposus on nerve root is related to the iuternal pressure of herniated nucleus pulposus; higher internal pressure in herniated nucleus pulposus would limit straight leg raising height while lower internal pressure has less effect. However, the compression of herniated nucleus pulposus on nerve root has no obvious relationship with the size of herniated nucleus compression by reducing the internal pressure in herniated nucleus pulposus, which may not only depend on changing the space-occupying of herniated nucleus pulposus.

Objective To assess the nutritional risk of patients with inflammatory bowel disease (IBD).Methods The nutritional status of 112 IBD patients from PUMC Hospital were evaluated by Nutritional Risk Screening 2002 (NRS 2002).Using Chinese standard,a body mass index (BMI) that was lowered than 18.5 kg/m~2 according to clinical material was regarded as malnutrition,and the score was recorded as 3.The se-verity of ulcerative colitis (UC) was evaluated using True-Love criteria as mild,moderate,and severe.Crohn's disease (CD) was evaluated using Harvey-Bradshaw Index as in remission stage (≤4),moderately active stage (4-8),and severely actively stage (≥9).Results All these 112 patients,including 70 UC cases and 42 CD cases,were evaluated by NRS2002.Forty-five patients (40.2%) were judged as at the risk of malnutrition.The incidence of malnutrition was significantly higher in CD patients than in UC patients (52.4% vs.32.9%,P<0.05).It was also significantly correlated with the severity of disease.In patients with severe IBD,the rate of mal-nutrition evaluated by BMI according to clinical material was significantly lower than the rate of nutritional risk.Con-clusions The risk of malnutrition is high in IBD patients.NRS 2002 can be used for nutritional risk screening.

Objective: To explore the early diaghostic value of thyroid hormone level in patients with left ventricular diastolic dysfunction. Methods: Our work included 4 groups:①Normal control group, n=40,②Impaired left ventricular diastolic function
group, n=40,③Failure of left ventricular diastolic function group, n=41 and④Impaired left ventricular systolic function group, n=40. The cardiac function was assessed by color Doppler lfow imaging and tissue Doppler imaging for the early diastolic mitral lfow velocity (E), the peak early diastolic mitral annular velocity (Em) and the ratio of E/Em. The blood levels of NT-proBNP and FT3, FT4, TSH, rT3 were examined in clinical laboratory.
Results: Blood levels of FT3 and rT3 were different in pair wise comparison among 4 groups, P<0.05, and FT4 and NT-proBNP were different in pair wise comparison among 4 groups, except for Normal control group and Impaired left ventricular diastolic function group, P<0.05. The TSH level was similar among 4 groups, P>0.05. The ratio of E/Em was negatively related to FT3 (r=-0.724, P<0.05) and FT4 (r=-0.49, P<0.05), while positively related to rT3 (r=0.87, P<0.05) and NT-proBNP (r=0.83, P<0.05).
Conclusion: The changes of thyroid hormone level may exist in patients with impaired diastolic function and it may vary with the severity of the cardiac dysfunction. Blood levels of NT-proBNP with thyroid hormone might be used as a reference index for early diagnosis of diastolic dysfunction.
