Objective To forward the concept of solution space of pharmacokinetics for studying radiophannaceutical distributions in animal models. Methods On the basis of special solutions of differential equations of pharmacokinetics, the solution space was established using the characteristics of linearly independent particular solutions and used to express the pharmacokinetics of pharmaceuticals in vivo. 0. 2 ml (7.4 MBq) 2β-carbomethoxy-3β- (4-corophenyl)-8-(2-18F-fluoroethyl) nortropane (18F-FECNT) was injected through tail vein into normal mice. The mice were sacrificed by decapitation at 5, 15, 30, 60, 120 and 180 min post-injection. Brain tissues were removed and weighed, and radioactivity was counted with the γ-counter. The solution space theory was used to study pharmacokinetics of 18F-FECNT in brain tissues of mice. Results The result showed that all solutions of pharmacokinetics models, based on differential equations, were included in the solution space. The solution of any organ or tissue could be linearly expressed by bases of the solution space. When the dimension number of the solution space was no more than 3, the solution could be directly expressed with coordinate picture. By this rule in our theory, the quantity of 18F-FECNT in brain tissues of mice changed with time, which was accorded with the experiment. The coordinates of striatum, frontal cortex, temporal cortex, occipital cortex, parietal cortex, hippocampus and cerebellum in the solution space were ( 10.13, 1.49), (4.27, 0. 84), (4.48, 0.81 ), (2.89, 0.98), (3.65, 0. 83),(3.55, 0. 98) and (2.03, 1.25 ), respectively. Conclusion The theory of solution space could be used to study pharmacokinetics of 18 F-FECNT in mice brain.

OBJECTIVETo study the clinical efficaly and safety of Tiepi Fengdou Granule (TFG) and Capsule (TFC) combined with chemotherapy and/or radiotherapy in treating lung cancer patients with Qi-Yin asthenia syndrome (QYAS).

METHODSEighty patients were randomly assigned into 3 groups: the TFG group (32 cases), the TFC group (32 cases) and the Shengmai Capsule control group (16 cases). Changes of symptoms of QYAS, main symptoms of lung cancer, Karnofsky scoring as well as the blood routine test were observed.

RESULTSThe total effective rate of symptom improving in the TFG group and the TFC group was 81.2% and 93.3% respectively, showing insignificant difference between the 2 groups (P > 0.05), but both were higher than that in the Shengmai Capsule control group (50.0%, P < 0.05 and P < 0.01). Additionally, as compared with those before treatment, the neutrophil count increased and the lymphocytes count obviously decreased in the TFC group after treatment (all P < 0.05).

CONCLUSIONBoth dose-forms of the remedies, TFC and TFG, have significant effects in treating lung cancer with QYAS, but with insignificant difference between them.

Objective To detect the levels of cytokine IL-2,IL-12,IFN-?and IL-4 secreted by peripheral CD8~+ T lymphocytes in patients with condyloma acuminatum (CA).Methods Flow cytometry was employed to study the expression of cytokines IL-2,-12,INF-?and IL-4 in CD8~+ T lymphocytes in the peripheral blood of 60 patients with CA and 20 healthy controls.Results The percentage of CD8~+ T lym- phocytes producing IL-2,IL-12 and IFN-?were significantly lower in CA patients than that in healthy con- trols (P

Background and purpose: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive method in the dignosis for mediastinal lymph nodes. This study was to evaluate the diagnostic yield of EBUS-TBNA for mediastinal lymph nodes. Methods: Twenty patients with mediastinal lymph nodes found by CT underwent the dignosis by EBUS-TBNA form April 1st 2009 to July 16th 2009. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results: Twenty patients with 37 lymph node groups were studied. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EBUS-TBNA for diagnostic were 84.62%, 100%, 100%, 77.78% and 90.00%, respectively. The diagnostic accuracy for cancer was 100%. The operation time was 11.9min per group in average with no serious complication. The median length of hospital stay was 1 (range from 1 to 17 days) day after operation. There were significant differences in the average operation time between the first three patients and the others (36.25 min vs. 7.76 min; z=3.247, P=0.001). Conclusion: Endobronchial ultrasound-guided transbronchial needle aspiration proved to be a safe procedure with a high yield for the diagnosis of mediastinal lymph nodes.

Background Interleukin-17 (IL-17)is a potent pro-inflammatory cytokine and plays a pathogenic role in autoimmune disease.It was confirmed that IL-17 is implicated in allograft rejection of many transplanted organs.Recent studies have foensed on the effect of IL-17 antagonists on allograft rejection.Objective This study aimed to investigate the inhibitory effect of anti-mouse IL-17 monoclonal antibody (mAb) on corneal allograft rejection.Methods Twenty-five 8 to 10-week-old C57BL/6 mice and 50 BALB/c mice were collected.Donor cornea grafts with 2 mm diameter from 25 C57BL/6 mice was transplanted to 50 eye of BALB/c mice to establish a model of corneal transplantation.The recipients were randomized into 2 groups,and neutralizing mouse IL-17antibody or isotype control antibody was intraperitoneally injected immediately after transplantation for experimental treatment,respectively.Allografts were scored clinically at appropriate time points after treatment based on Plskova criteria,and ≥5 was confirmed as rejection.Infiltrating cells in corneal graft were detected qualitatively and quantitatively by immunohistochemistry and reverse transcription-PCR separately.The cytokine levels of T helper type 1 (Th1),Th2,and Th17 in recipients' spleen wer(c) analyzcd by ELISA.The use of the animals followed the Statement of ARVO.Results Compared with the isotype control antibody group,the survival of grafts was improved in the IL-17mAb group(P＜0.05).The levels of neutrophile granulocyte mRNA,CD4+ and CD8+ T lymphotes mRNA were 2.22±0.10,1.64±0.04 and 1.32±0.10 in the IL-17 mAb group,showing a significant decline in comparison with those of the isotype control antibody group(3.61 ±0.08,2.69±0.06 and 2.17±0.04) (P=0.000,0.000,0.000).Interferon-γ(IFN-γ),IL-12 p40 and IL-17 concentrations in recipients ' splenocytes were (529.80 ± 13.83) ng/L,(539.58 ±10.74) ng/L and(173.70±8.11)ng/L in the IL-17 mAb group,and thosc in the isotype control antibody group were (741.48± 10.51) ng/L,(1156.90 ± 69.93) ng/L and (366.13± 7.93) ng/L,with significant differences between them (P=0.000,0.001,0.000).Conclusions Neutralization IL-17 bioactivity inhibits mouse corneal allograft rejection to a certain extent.

AlM: To explore the different ages of congenital nasolacrimal duct obstruction in infants, take different treatment methods at different times.
METHODS:The 87 cases of 102 children were divided into three different age groups: the first group of 25d-3mo of age 21 cases 26 eyes; The second group >3mo-7mo 31 cases 36 eyes;The third group >7-24mo of age 35 cases 40 eyes. For the first group of infants, the implementation of the lacrimal sac nasolacrimal duct massage + eye drops; for the second group of infants, carry lacrimal pressure washing treatment; for the third group of infants, the implementation of the nasolacrimal duct probing treatment.
RESULTS: The first group of children through the nasolacrimal duct sac massage + drops tobramycin eye drops treatment unobstructed 12, the cure rate was 46. 2%;The second group of children through pressurized irrigation treatment lacrimal patency by 33, the cure rate was 91. 7%; The third group of children through the nasolacrimal duct probing unobstructed 36 treatment, the cure rate was 90. 0%. The second and third group were better than the first group (χ2=15. 71, P<0. 01;χ2=15. 27, P<0. 01);the treatment effect of the second and third groups was no significant difference (χ2=0. 02, P>0. 05).
CONCLUSlON:lnfants with congenital nasolacrimal duct obstruction should distinguish between ages, taking different treatments, in order to obtain a better therapeutic effect, and lacrimal pressure washing is the preferred way of treating infants with congenital nasolacrimal duct obstruction.
