Objective]To explore the clinical value of the theories in the seven papers of Yunqi.[Method] Analysing the usage of the correlation theories of Yunqi in Cases of Well-known Physicians and its sequel, consulting the commentaries and application of many well-known physicians, this paper summarizes some theories which are applicable to clinic.[Result]In the seven papers of Yunqi, the theory of avoidance of harm by restraining excess and the theory about the inconformity of pulse and disease can exclude false symptoms and infer real pathogenesis.19 questions about pathogenesis can be a reference of clinical diagnosis.The theory of South-North can be used to exclude the impact of climate on the pulse and assist diagnosis. Rationally using the theory of Suiyun contributes to infer etiology and establish therapy.[Conclusion]Cases of Well-known Physicians and its sequel reflect the application and exertion of the theories of Yunqi by ancient physicians. They help to understand the theoretical system and instruct clinical application. In addition to the theory of Suiyun, the seven papers of Yunqi also include a lot of theories which are applicable to clinic.

Objective To study the effect of mecobalamine treatment on acute cerebral infarction combined with high homocysteine (Hcy) and post-stroke depression.Methods A total of 160 cerebral infarction patients with high Hcy were collected from January 2010 to December 2011 in our hospital.Patients were randomly divided into two groups:the control group (n=80,with routine therapy) and the treatment group (n=80,with routine therapy plus intramuscular injection with folic acid 500μg for 8 weeks).The plasma concentration of Hcy was determined by fluoresene polarization immunoassay.The improvement of depression,anxiety and life skills in patients were assessed by selfmade questionnaires and self-reporting inventory (SLC 90).Results There were no significant differences in plasma Hcy level in control group before versus after treatment [(21.86±4.76) μmol/L vs.(18.67±3.81) μmol/L,t=0.40,P＞0.05].Compared with before treatment,plasma Hcy level in treatment group was significantly reduced 4 weeks after treatment [(11.66 ± 3.28) μmol/L vs.(22.68±5.16) μmol/L,t=2.55,P＜0.01].There was a significant difference in plasma Hcy level between the treatment group and the control group after treatment [(11.66 ±3.28) μmol/L vs.(18.67±3.81) μmol/L,t=7.40,P＜0.01].TheSCL-90 total score,positive symptom items score,the total score and the average score of positive symptom items were significantly lower in treatment group after treatment than in treatment group before treatment (t=2.04,2.97,5.45,4.21,all P＜0.05) and in control group after treatment (t 7.40,7.58,12.78,4.15,all P＜0.05).The improvement on symptomatic patterns including somatization,obsessive-compulsive problems,interpersonal sensitivity,depression,anxiety and fear were better in treatment group after treatment than in treatment group before treatment (t 2.34,2.28,2.51,2.19,3.40,2.35,allP＜0.05) and in control group after treatment (t=4.10,5.04,5.12,4.18,5.48,5.20,all P＜0.05).There were no significant differences in the improvement in paranoid ideation between the treatment group before and after treatment (t=1.40,P＞0.05),between the treatment group and the control group after treatment (t=1.48,P＞0.05),and between the control group before and after treatment (P＞0.05).Conclusions Mecobalamine can effectively reduce plasma Hcy level in cerebral infarction patients with high plasma Hcy,and alleviate the symptoms of anxiety,depression,nervousness and other emotions.

A case of traumatic delayed meningo-encephalocele suffered orbital fracture, but bony defects in frontal sinus had not been found on CT scanning. We treated the patient with surgery of intranasal endoscopy and repaired the skull base defect successfully during the first attempt. There was no recurrence in 10 months followed up. The leak site may not correlate with imaging in traumatic delayed meningo-encephalocele by comparing operative findings with the imaging estimate and endoscopy. Therefore, endoscopical approaching is effective in seeking and treatment.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

Objective To evaluate the radiobiological effect of different irradiation fractionated regimens in human glioma cells ( BT 325 cell line). Methods The xenografts in Balb/c-nude mice were irradiated with different single and fractionated regimens. The single fraction dose was 10, 20, 30, 40 and 60 Gy, respectively. The fractionated regimens were 2 Gy × 5 fractions ( irradiated every day), and 3 Gy ×3 fractions (irradiated every other day), 3 Gy × 5 fractions (irradiated every day) and 4 Gy × 3 fractions (irradiated every other day), with total doses of 125 Gy, 114 Gy, 126 Gy and 112 Gy, respectively. The growth curve was used to evaluate the tumor doubling time. clonogenic assays was performed to draw the cell survival curve and analyze the radiobiological parameters with doses of 1, 2, 4, 6, 8 and 10 Gy. T1/2 was measured by comet assay. Results Tumor regression were not observed by single fraction irradiation, 2 Gy × 5 fractons and 3 Gy × 3 fractions irradiation regimens. The tumor regress was more significant with the increas of fraction dose. The 4 Gy × 3 fractionrs inhibited tumor more though not curing tumor. The cell doubling time of the BT 325 cell was 30. 16 h and the tumor doubling time of the xenograft was 43 days.When fitted with L-Q model ,α was 0. 36 Gy -1 and β was 0. 057 Gy -2. When fitted with the single-hit multitarget model, D0 was 1. 394 Gy, Dq was 2. 127 Gy and SF2 was 0. 714, respectively. The T1/2 was 9. 999min. Conclusions Glioma is a radioresistant tumor. Increase of the fraction dose improves recent effect.Further study is needed to control the tumor stem cells.

A molecularly imprinted two-dimensional photonic crystal hydrogel sensor was developed with erythromycin as imprinted molecule, polystyrene two-dimensional photonic crystal as templates, methanol as solvent, methacrylic acid as monomers and ethylene glycol dimethylacrylate as cross-linkers.The imprinted molecule was removed by methanol/acetic acid (9∶1, V/V).The results showed that the diameter of Debye ring increased 6 mm when the concentration of EM changed from 0 to 1×10-6 mol/L.Namely the lattice spacing decreased 30 nm.In addition, the diameter of Debye ring only increased 1.5 and 2.0 mm when the hydrogel immersed in 1×10-6 mol/L roxithromycin (RM) or erythromycin ethylsuccinate (EEs) solution.The result indicated that the sensor had high selectivity and could be used in determination of erythromycin with low cost and easy operation.

Objective To observe the expression of Na+/I- symporter(NIS) in cultured lactating mammary cells with different levels of iodine and the effect of tumor necrosis factor-α(TNF-α). Methods Original generation of mouse lactating mammary cells cultured in vitro were divided into low iodine group Ⅰ (LI-Ⅰ), low iodine group Ⅱ (LI-Ⅱ), adequate iodine group(AI), high iodine group Ⅰ(HI-Ⅰ), and high iodine group Ⅱ(HI-Ⅱ). Cells were cultured in DEME/F12 culture medium for 24 h with different concentrations of iodine (0,5,50,3000 and 10 000 μg/L, respectively), and TNF-α( 10-2 mg/L) was added to some of cultured cells for 24 h. The expression of NIS mRNA of lactating mammary cells was determined by real-time quantitative PCR and the expression of NIS protein was detected by In-Cell Western. Results In iodine alone group, the expression of NIS mRNA in LI-Ⅰ group [ (64.66 ± 14.99) x 10-4] was higher than that of AI group[ (22.76 ± 7.36) × 10-4, P ＜ 0.01 ]; HI-I group[ (10.18 ±3.53) × 10-4] and HI-Ⅱ group[ (8.59 ± 2.89) × 10-4] were lower than that of AI group(all P ＜ .0.05); With increased iodine concentration, the expression of NIS mRNA decreased. The expression of NIS mRNA in LI-Ⅰ group [(2.72 ± 0.45) × 10-4], LI-Ⅱ group[ (2.69 ± 0.68) × 10-4] and AI group[(1.80 ± 0.67) × 10-4] with iodine plus TNF-o were all lower than that of LI-Ⅰ group, LI-Ⅱ group[ (29.82 ± 4.47 ) × 10-4], and AI group without TNF-α (all P ＜ 0.01). In iodine plus TNF-α, the expression of NIS mRNA in HI-Ⅰ group[(6.58 ± 2.87) × 10-4] and HI-Ⅱ[(7.04 ± 1.36) × 10-4] group were all higher than that of AI group(all P ＜ 0.05); With increased iodine deficiency or iodine excess, the expression of NIS mRNA increased. With increased iodine concentration, the expression of NIS protein decreased in iodine alone group. The expression of NIS protein in iodine plus TNF-α was all lower than that in iodine alone group. In iodine plus TNF-α, the expression of NIS protein increased in both iodine deficiency and iodine excess conditions. Conclusions Iodine may decrease the expression of NIS mRNA and protein of lactating mammary cells. The expression of NIS mRNA and protein of lactating mammary cells was inhibited by TNF-α under different levels of iodine.

ObjectiveTo study the morphological and functional changes of thyroid in lactating rats and their offspring in iodine deficiency and iodine excess animal models.MethodsOne hundred and twenty Wistar rats(30 males and 90 females) were selected.Based on their body weight,the 90 females were stratified and randomly divided into five groups( 18 in each group):low iodine group 1 and group 2(fed with low iodine feed and deionized water containing iodine of 0,5 μg/L) ; high iodine group 1,group 2 and control group(feed with normal diet and deionized water containing iodine of 3000,10 000,50 μg/L).After fed for 3 month,all female rats were mated with males in a ratio of 3 ∶ 1.After birth for 10 days,8 female rats and their offspring in each group were sacrificed.Changes of thyroid were observed by naked eyes.The thyroid weight was measured and pathological changes of thyroids were observed under light microscope.Results①Absolute and relative weight of lactating rats thyroid in low iodine group 1 and group 2 [ (92.02 ± 24.40 ),(77.11 ± 23.32 )mg,(0.509 ± 0.072),(0.384 ± 0.089) mg/kg] were much higher than that of control group[ (17.41 ± 9.25)mg,(0.102 ± 0.016)mg/kg,all P＜ 0.05].Absolute and relative weight of lactating rats thyroid in high iodine group 1 and group 2[(8.22 ± 0.41 ),(9.42 ±0.43)mg,(0.047 ± 0.006),(0.035 ± 0.005)mg/kg] were lower than that of control group(all P ＜ 0.05).Absolute and relative weight of lactating rats and their offspring thyroid was decreased with increase of iodide intake in the diet.②Thyroid enlargement of lactating rats in low iodine group 1 and group 2 was evident,but that of high iodine group 1 and group 2 was not.③Epithelial cell hyperplasia and smaller follicular cavity were observed in low iodine group 1 and group 2 under light microscope.Epithelial cell deformation and mostly flat were observed in high iodine group 1 and group 2.ConclusionsThyroid morphology is changed with iodide intake in the lactating rats and their offspring,and the changes are consistent between female rats and their newborns.

ObjectiveTo evaluate the efficacy and safety of domestic taerolimus in the manage-ment of acute rejection in renal transplantation reeipienta.MethodsA multieeneter, open and com-parative study for domestic Taerolimua and Prograf was performed. Eighty reeipienta of first allogenie renal transplantation were randomized into 2 groups: ①Experimental group (accepting Fumeixin ad-ministration, n=58) included 23 males and 35 females with the mean age of(39.1±9.6)years. ②Control group(accepting Prograf administration, n=22) included 12 males and 10 females with the mean age of(41.34±8.5)years. There was no significant difference in the volume, warm and cold is-chemia time of donor renal, age and sex of donor. All of the 80 cases accepted tacrolimus (domestic or foreign made, at the dose of 0. 10～0. 15 mg·kg-1·d-1 , q 12 h) treatment that combined with MMF and prednisone posttransplantation. Tacrolimus CO was aimed to 8-12 ng/ml in the first 60 days and 5-10 ng/ml later. The dose of MMF was according to the rule of each transplantation center based on the following recommendation: 1.5-2.0 g/d for the weight above 70 kg, 1.5 g/d for the weight 50-69 kg, and 1.0 g/d for the weight below 49 kg, in two divided doses. Prednisone was ad- ministrated as per ruler of each center. ResultsObservation termination was 3 months. Morbility of actue rejection was 3.40% (2/58)and 13.6% (3/22) in experimental and control group(P>0.05). Ad-verse events including hypertension, hyperlipemia, hyperglycemia and slight abnormality of liver func-tion occurred in 36. 2%(21/58) and 36. 4% (8/22) cases of experimental and control group(P> 0. 05). The survival rate in the 2 groups was 100%. The dose of tacrolimus in experimental group was significantly lower than that in the control group at 8 and 12 weeks posttransplant, while drug valley concentration in serum was proximal in 2 groups during the whole observation period.Conclusion Domestic tacrolimus capsules can be used effectively and safely in the management of acute rejection in renal transplantation.
