Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

Objective To observe the clinical efficacy of stage-based treatment of peripheral facial paralysis with Yifeng (TE 17) selected as the major point treated by different acupuncture methods.Method A total of 102 patients with peripheral facial paralysis were randomized into a treatment group and a control group, 51 cases each. The treatment group was intervened by selecting Yifeng (TE 17) as the major point, treated with centro-square needling in the acute stage, triple needling in the resting stage, and proximal needling in the remission stage; the control group was intervened by ordinary acupuncture. The two groups were treated once a day, 5 d as a course of treatment. Before and after 3 treatment courses, the House Brackmann (HB) facial nerve grading scale and Visual Analogue Scale (VAS) in those patients complicated with pain were observed, and the clinical efficacies were compared.Result The total effective rate and recovery rate were respectively 100.0％ and 82.3％ in the treatment group versus 86.3％ and 60.8％ in the control group, and the between-group differences were statistically significant (P<0.05). The HB scores were significantly changed respectively after 1, 2 and 3 treatment courses in the two groups compared with the pre-treatment scores (P<0.05). The HB scores in the treatment group were significantly different from those in the control group respectively after 1, 2 and 3 treatment courses (P<0.05). The patients complicated with facial pain or headache presented significant differences in VAS score respectively after 1, 2 and 3 treatment courses in the two groups (P<0.05). In comparing the VAS score in the patients complicated with facial pain or headache, there were significant differences between the two groups respectively after 1, 2 and 3 treatment courses (P<0.05).Conclusion Stage- based treatment with Yifeng (TE 17) selected as the major point treated with different acupuncture methods can produce valid efficacy in treating peripheral facial paralysis.

Objective To investigate the clinical efficacy of staging treatment with various acupuncture therapies mainly on Yifeng (TE17) point for the treatment of peripheral facial paralysis. Methods One hundred and two peripheral facial paralysis patients were randomly divided into trial group and control group, 51 patients in each group. The trial group was given acupuncture mainly on Yifeng point, by Yang needling(plum-blossom needling) for acute stage, Qi needling(concentrated triple-needling) for resting stage and Bang needling(lateral needling) for recovery stage. The control group was given conventional acupuncture. The treatment for the two groups was performed once a day, 5 continuous days constituted a course, and the treatment lasted 3 courses. Before treatment and after treatment for 1, 2, 3 course (s), facial nerve function scores were evaluated with House-Brackmann Grading Scale (HB) and the scores of pain in head and face were evaluated with Visual Analogue Scale (VAS). And the clinical efficacy of the two groups was assessed after treatment. Results (1) After treatment for 3 courses, the cure rate and total effective rate of the trial group were 82.35％, 100.00％, and those of the control group were 60.78％, 86.27％, respectively. The differences between the two groups were significant (P <0.05). (2) After treatment, HB scores and VSA scores of patients with facial pain and headache in the two groups were improved after treatment (P < 0.05 compared with those before treatment), and the improvement in the trial group was superior to that in the control group (P < 0.05). Conclusion Staging treatment with various acupuncture therapies mainly on Yifeng point is more effective for the treatment of peripheral facial paralysis than conventional acupuncture.

OBJECTIVETo investigate the effect of garlicin on the levels of interferon gamma (INF-gamma) and interleukin 4 (IL-4) in blood of allergic rhinitis rat model.

METHODSThirty healthy female SD rats were randomly divided into 3 groups: control group, negative control group and experimental group, 10 rats for each group. Ten rats (experimental group) were sensitized and intranasally challenged by ovalbumin, aluminium hydroxide hydrate gel and Bordetella pertussis inactive microorganism suspension adjuvants, as allergic rhinitis models, and then injection of garlicin(0.4 ml) intraperitoneally per day for 10 days. Control group rats were immunized as experimental group, and then injection of physiological saline as equal volume as garlicin. Negative control group rats were investigated using physiological saline. Blood of intrajugular vein of rat was extracted for separated plasma Enzyme liked immunosorbent assay (ELISA) was utilized to detect the serum levels of IL-4 and IFN-gamma.

RESULTSThe serum levels (x +/- s) of IL4 were (22.81 +/- 8.79) pg/L, (41.43 +/- 4.93) pg/L, (9.93 +/- 2.07) pg/L, and those of IFN-gamma were (22.32 +/- 11.20) pg/L, (11.35 +/- 2.45) pg/L and (21.69 +/- 5.93) pg/L, respectively, among experimental group, control group and negative control group. The serum level of IL-4 in experimental group rats was lower than value of control group rats (t = 3.22, P < 0.05), while higher than negative control group (t = 4.17, P < 0.05). The serum level of IFN-gamma was increased significantly in experimental group rats with significant difference when compared with value of control group rats (t = 3.84, P < 0.05), while no difference was shown between experimental group and negative control group (t = 1.47, P > 0.05).

CONCLUSIONSGarlicin could increase serum level of INF-gamma and decrease serum level of IL4 significantly in allergic rhinitis rat model. It played an important role on regulating serum levels of cytokines of Thl and Th2.

OBJECTIVEThis study is aimed to observe the natural draining state of maxillary sinus, to search for the key draining location (KDL) in the natural ostium, to investigate the relation between maxillary sinus draining and sinus inflammation, and to guide the treatment of maxillary sinus opening in endoscopic sinus surgery (ESS).

METHODSMethylene blue was used as tracer agent in this study. Fifteen cases with or without light maxillary sinus inflammation (without any treatment) were selected to observe the natural draining state and the key draining location in maxillary sinus fontanel. Eighty-nine cases with chronic rhinosinusitis, but without nasal polyp, were selected, of which the maxillary sinus mucosa restored well 6 months after ESS, to observe the draining state and modes in maxillary sinus. All patients were followed up for 12 months to evaluate the inflammation state of mucosa, and to analyze the relations between the draining mode and mucosa inflammation.

RESULTSThe KDL for maxillary sinus was located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process. The draining flowed along it from maxillary sinus to nasopharynx. After conventional transnasal endoscopic operation, 15 cases showed relatively normal drainage, others displayed abnormal state and mode,including reverse draining (maxillary sinus-ethmoid sinus) , multiphase draining (outflow from front, back and lower wall of natural ostium), draining failure (with cilia transporting function of maxillary epithelium mucosae), cistern like change (maxillary sinus and ethmoid sinus formed one operation cavity, secretion accumulated in maxillary sinus) and mucosa disfunction (loss of cilia transporting function of maxillary epithelium mucosae). Inflammation was observed in 33.7% of the patients 12 months after ESS, especially in those with mucosa disfunction, draining failure and reverse draining.

CONCLUSIONSThe KDL for maxillary sinus may be located in the posterior-inferior portion of the natural ostium, close to the attachment of caudal end of the uncinate process, and the drainage mode is not affected by gravity and posture. The KDL lesion after ESS results in abnormal draining of maxillary sinus, and excessively large maxillary sinus opening may aggravate mucosa inflammation of maxillary sinus. The abnormal draining state and mode may be related with the incidence of mucosa inflammation after operation. Preserving caudal end of uncinate process and avoiding injury of KDL would be beneficial to the restoration of mucosa and lessen the incidence of inflammation recurrence.

In order to study the value of sequential and quantitative analysis of chimerism in determination of optional time of donor lymphocyte infusion (DLI) and prediction of efficacy of DLI, six patients with leukemias who relapsed or failed of engraftment were treated with DLI. Serial and quantitative analyses of donor chimerism (DC) both prior to and following DLI were performed by multiplex PCR amplification of STR markers (STR-PCR) and capillary electrophoresis with fluorescence detection. The results showed that at the time of relapse or graft rejection, STR-PCR indicated the decreasing donor chimerism in all six patients, at levels ranging from 27.3% to 85.7%. The declining value of DC (<90%) was detected in four patients at 26 days before relapse or graft rejection diagnosed clinically. Therefore the decrease of value of DC can be identified the high risk of relapse or graft failure and can be used to guide DLI implementation at early stage. In this study the clinical response were seen in two patients, the value of DC in these patients increased with convertion to a predominant donor profile (>90%) or converted to stable FDC shortly after DLI, while in the patients without clinical response, the level of DC decreased persistently or declined after transient increase. Three patients without response received second DLI. It is concluded that the monitoring of chimerism is proved to be a valuable to determine the optional time point of DLI and to early evaluate the efficacy of DLI. Furthermore, it can present a rational basis for treatment of intensification in the patients who did not respond to first-line DLI treatment.

AIMTo study the effect of different intervals between occlusions of vertebral arteries and bilateral common carotid arteries on the Pulsinelli 4-vessel occlusion global cerebral ischemic model, and the features of ischemia of the brainstem and hippocampus induced by occulusion of bilateral common carotid arteries under the condition of occlusion of unilateral vertebral artery.

METHODSEighty four adult male Wistar rats were divided into 4 groups randomly: control group, bilateral vertebral artery occluding group, global brain ischemic insult group, and unilateral vertebral artery occluding plus bilateral common carotid arteries occluding group. In the global brain ischemic insult group, rats were further divided into 24 h, 48 h, and 72 h interval subgroups according to the interval between the occlusion of the vertebral arteries and bilateral common carotid arteries. The responses including enlarging of pupils and the light reflex during the brain ischemia were observed. The duration of right reflex disappearing, the general state, and the delayed neuronal death (DND) of pyramidal neurons in the CA1 hippocampus of the rats after the brain ischemia were also observed.

RESULTSAmong the global brain ischemic insult group, both the responses and DND were more severe in 72 h interval subgroup than those in 24 h and 48 h interval subgroups. There was no significant difference between 24 h and 48 h interval subgroups. When the bilateral common carotid arteries were occluded under the condition of occlusion of unilateral vertebral artery, severe DND was observed in the CA1 hippocampus ipsilateral to the occluding vertebral artery, but no significant DND was observed in the contralateral CA1 hippocampus.

CONCLUSIONThe results suggested that the prior occlusion of the bilateral vertebral arteries during producing Pulsinelli 4-vessel occlusion global cerebral ischemic model might be a cerebral ischemic preconditioning that could protect to some extent pyramidal neurons of the hippocampus against severe ischemic insult induced by occlusion of bilateral common carotid arteries within 48 h. Moreover, There is ipsilateral predominance of blood perfusion from one side of vertebral artery to the brainstem and hippocampus, although there was Willis artery circle in rats.

OBJECTIVETo reverse the multidrug resistance (MDR) property of carcinoma cells by blocking transcription of activating sites of mdr-1.

METHODSBreast carcinoma cells were transinfected with several antisense oligonucleotide (ASODN) complementary to mdr-1 by lipofectin. RT-PCR was used to detect the production of mdr-1mRNA. The expression of P-glycoprotein (gp) was then detected by immunohistochemistry and the function of P-gp was detected by rhodamine123 retention.

RESULTSForty-eight hours after transfection, mdr-1 index of cells treated by ASODN complementary to MA zone (major initiation start zone), MI (minor initiation start zone), C zone (CAAT box), G zone (GC box) of mdr-1 gene was 1.4, 1.9, 1.6 and 2.1 respectively. The rate of P-gp protein expression in treated cells was 14%, 43%, 26% and 39% respectively. The intracellular Rh123 retention in treated cells was 125%, 83%, 102% and 77% respectively. There was significant difference between cells treated by ASODN complementary to MA zone and C zone and drug-resistant cells.

CONCLUSIONSThe ASODN complementary to MA zone and C zone of mdr-1 gene can reverse MDR of drug-resistant cells to various extent, amongst which the former is more effective. Down-regulating transcription of mdr-1 by blocking transcription activating sites can reduce the expression of mdr-1mRNA and P-gp, and thus reversing MDR of carcinoma cells. The ASODN complementary to MI zone, G zone of mdr-1 however do not significantly reverse the MDR property.
