BACKGROUND: In the research, the recipe for kidney tonification is prepared into "topical form" and "oral form". According to the interrelationship of "acupoints-meridans and collaterals-internal organs-target organs", osteoporosis is treated by the approaches of point compress and oral application respectively. According to the traditional theory of Chinese medicine, it is to infer that the herbs bring the adjustment into play by"being attributive to kidney meridian", but,whether does the specialty of herbs on "targeting medication" happenpractically or not? Hormones in "hypothalamus-pituitary- target gland" system is assayed to further analyze estrogen receptor and androgen receptor of target organs,such as kidney,bone, uterus, thyroid gland and testis so as to observe the relativity between "tropism and receptor".DESIGN: Complete random design with the objects of osteoporosis rats, and the control experimental study with kidney tonification recipe administrate with different approaches.OBJECTIVE: To probe into the effect of kidney tonification recipe on pituitary-thyroid axis in experimental osteoporosis.SETTING: College of Traditional Chinese Medicine of Hebei Medical University.MATERIALS: The experiment was performed in Chinese-Western integrated Basic Experiment Room of Hebei Medical University from January 2000 to December 2004. Sixty SD healthy female rats of 3-month old were employed,weighted(300 ± 20) g. The experimental animals were provided by Hebei Experimental Animal Center. After bred routinely for 1 week in Experimental Room, the rats were randomized into 6 groups,namely normal control(10rats), pathological model group(10 rats), infusing group(10 rats) in which kidney tonification recipe was applied based on 0. 8 g/100 g body mass,acupoint paste on bladder meridian group (10 rats), acupoint paste on kidney meridian group(10 rats) and paste on non-meridian group(10 rats). METHODS: Osteoporosis model was prepared with injection of dexamethasonc. Antagonism osteoporosis acupoint paste(AOAP)on acupoints and non-neridian places was administrated to compare with oral recipe for kidney tonification in the treatment of osteoporosis. It took the changes in serum estrogen, bone density, calcitonin/parathyroid hormone(CT/PTH), thyrotropic hormone(TSH), freeT3andfreeT4asthemeasuringindexes. Immunocyto-chemistry stain and morphological measurement of TSH cell,follicular adenoma of thyroid gland(C cell) and thyroid globulin(Tg) were applied in pituitary gland and thyroid gland to observe the therapeutic results.MAIN OUTCOME MEASURES: ① Adjustment of the recipe for kidney tonification on thyroid function. ② Adjustment of the recipe for kidney tonification on bone density.RESULTS: AOAP improved the levels of estrogen, CT/PTH, TSH, free T3and free T4, increased bone density. The counts of TSH cell, C cell and Tg positive reaction substance were increased and they were colored deeply.CONCLUSION: AOPA, by "multiple relevant convergence reaction", adjusts and affects systematically the endocrinal function of bone metabolism,improves the levels of estrogen and CT/PTH, reverses the declining tendency of pituitary-thyroid axis function and improves thyroid function so as to weaken osteocyte in the bony absorption, enhance osteoblast in osteogenesis and increase bone density.

OBJECTIVEIn order to get the method for improving the salt resistance of Lycium ruthenium seeds and seedlings under NaCl stress, the seed germination and physiological characteristics of L. ruthenium seedlings was studied.

METHODSeveral physiological indexes of L. ruthenium seeds under NaCl stress, such as the germination rate (Gr), germination vigor (Gv), germination index (Gi), vigor index (Vi), and relative salt damage rate were measured. Other indexes of the seedlings like relative water contents (RWC) , chlorophyll contents, soluble protein contents, electrolyte leakage, the contents of malondialdehyde (MDA), and peroxidase (POD) were also measured.

RESULTNaCl at lower concentration could promote the seed germination but inhibit the seed germination at higher concentration. After the treatment by CaCl2 at the different concentrations, all germination indexes were increased. With the increase of salt concentration, the relative water contents and the contents of chlorophyll were decreased, the content of MDA and electrolyte leakage were increased. The change trend of POD activity showed the first increase and then decrease with the increase of salt concentration, which was similar to that of the soluble protein. After the treatment by CaCl2, relative water contents, chlorophyll and POD activities were decreased more slowly, and also electrolyte leakage and MDA contents increased slowly.

CONCLUSIONThe CaCl2 could significantly alleviate the damages to the seeds and seedlings of L. ruthenium under NaCl stress, and promote the salt resistance to the seeds and seedlings of L. ruthenium.

BACKGROUND:Sepsis has become the greatest threat to in-patients, with a mortality of over 25％.The dysfunction of gut barrier, especially the immunological barrier, plays an important role in the development of sepsis. This dysfunction occurs after surgery, but the magnitude of change does not differentiate patients with sepsis from those without sepsis. Increased intestinal permeability before surgery is of no value in predicating sepsis. The present study aimed to observe the changes of intestinal mucosal immunologic barrier in rat models of sepsis induced by cecal ligation and puncture. METHODS:Sixty Sprague-Dawley rats were randomly divided into a sepsis group (n=45) and a control group (n=15). The rats in the sepsis group were subjected to cecal ligation and puncture (CLP), whereas the rats in the control group underwent a sham operation. The ileac mucosa and segments were harvested 3, 6 and 12 hours after CLP, and blood samples were collected. Pathological changes, protein levels of defensin-5 (RD-5) and trefoil factor-3 (TFF3) mRNA, and lymphocytes apoptosis in the intestinal mucosa were determined. In an additional experiment, the gut-origin bacterial DNA in blood was detected. RESULTS:The intestinal mucosa showed marked injury with loss of ileal villi, desquamation of epithelium, detachment of lamina propria, hemorrhage and ulceration in the sepsis group. The expression of TFF3 mRNA and level of RD-5 protein were decreased and the apoptosis of mucosal lymphocyte increased (P<0.05) in the sepsis group compared with the control group. Significant differences were observed in RD-5 and TFF3 mRNA 3 hours after CLP and they were progressively increased 6 and 12 hours after CLP in the sepsis group compared with the control group (P<0.05, RD-5 F=11.76, TFF3 F=16.86 and apoptosis F=122.52). In addition, the gut-origin bacterial DNA detected in plasma was positive in the sepsis group. CONCLUSION:The immunological function of the intestinal mucosa was impaired in septic rats and further deteriorated in the course of sepsis.

OBJECTIVETo evaluate autogenous vein grafts and inside-out vein grafts as conduits for the defects repair in the rabbit facial nerves.

METHODSThe 10 mm segments of buccal division of facial nerve were transected for 48 rabbits in this study. Then the gaps were immediately repaired by autogenous vein grafts or inside-out vein grafts in different groups. All the animals underwent the whisker movement test and electrophysiologic test during the following 16 weeks at different time points postoperatively. Subsequently, the histological examination was performed to observe the facial nerve regeneration morphologically.

RESULTSAt 8 weeks after operation, the facial nerve regeneration has significant difference between the experimental group and the control group in electrophysiologic test and histological observation. However, at the end of this study, 16 weeks after operation, there was no significant difference between inside-out vein grafts and standard vein grafts in enhancing peripheral nerve regeneration.

CONCLUSIONThis study suggest that both kinds of vein grafts play positive roles in facial nerve regeneration after being repaired immediately, but the autogenous inside-out vein grafts might accelerate and facilitate axonal regeneration as compared with control.

OBJECTIVETo understand the relationship between the HIV-1 viral sequence variation and host factors associated with HIV-1 disease progression.

METHODSEnv and gag fragments of HIV-1 were amplified with PCR, cloned and sequenced. Bioinformatics was employed to find the genetic variation, N-linked glycosylation, hypermutation etc. Host gene polymorphism was analysed by using restricted fragment length polymorphism (RFLP).

RESULTSSignificant difference was found in genetic divergence between Env PCR dominant and clonal sequences (0.1 and 0.06, respectively) in non-treated group, but no significant difference was found in the HAART treated group. V3 GPGQ accounted for the most part in both treated and nontreated groups, rare V3 loop such as GPGH, GQGR and GLGR was found in treated group, V3 substitutions of I/V (position 12) and Y/H (position 21) was associated with the relatively rapid progression (RRP). Glycosylation was significantly higher in RRP than in TP for Env region, GA substitution in RRP was also significantly higher than that in TP group. SDF1-3primeA and CCR2 V64I gene frequency was higher in TP than in RRP, but the difference was not significant.

CONCLUSIONDisease progression was associated with V3 AA change, glycosylation and GA substitution in env gene. SDF1-3primeA, CCR2 V64I and CX3CR1 V249I/M280T was not associated with disease progression significantly.

The aim of this study was to explore the effects of cholecystokinin octapeptide (CCK-8) on cardiac function and the receptor mechanism in anesthetized rats. The mean arterial pressure (MAP), heart rate (HR), the left ventricle systolic pressure (LVP) and the maximal/minimum rate of LVP (+/-LV dp/dt(max)) were measured. The results obtained are as follows. (1) Low dose of CCK-8 (0. 4 microgram/kg i.v.) caused tachycardia and slight increase in MAP, LVP and LV dp/dt(max) (P<0.01), while medium dose (4.0 microgram/kg i.v.) and high dose of CCK-8 (40 microgram/kg i.v.) elicited a bradycardia and marked increase in MAP, LVP and LV dp/dtmax (P<0.01). (2) Proglumide (1.0 mg/kg i.v.), a CCK-receptor (CCK-R) antagonist, significantly inhibited the pressor effects of CCK-8, whilst it reversed the bradycardic responses (P<0.01). (3) Using reverse transcription polymerase chain reaction (RT-PCR), CCK-A receptor (CCK-AR) and CCK-B receptor (CCK-BR) mRNA were expressed in myocardium of rats. The above results indicate that CCK-8 may enhance cardiac function in a dose-dependent manner and elicit a change in HR, which is likely induced by the activation of CCK-R on myocardium.

OBJECTIVETo investigate the changes in the bacterial ecology and to analyze the bacterial resistance to antibiotics in a burn ward in Nanning district during the past 15 years, so as to provide reference to the clinical management of burn infection under subtropical climate.

METHODSFive thousand eight hundred and fifty-five strains of bacteria were isolated from the wounds and blood of 2269 burn patients admitted to our hospital from April of 1989 to March of 2004. Kiry-Bauer method was employed for the detection of antibiotic sensitivity test. The bacterial examination and bacterial resistance were analyzed in spans of every five years.

RESULTSBurn patients in our district were mainly infected by the gram negative bacilli (3559 strains, accounting for 60.79%), among which Pseudomonas aeruginosa, Enterobacter cloacae and Nitrate negative bacilli were major ones in every period. Gram positive cocci accounted for 33.99% (1990 strains), which ranked the second, among which Staphylococcus aureus, Staphylococcus epidermidis, and Coagulase negative staphylococci (MRCNS) were the most predominant ones. The bacterial resistance to multiple antibiotics, such as Gentamicin, third generation of Cephalosporin, and Norfloxacin showed a tendency of increase or maintained at high level while the incidence of resistance to Imipenem and Vancomycin was very low.

CONCLUSIONThe climate and the way of using antibiotics exerted direct effects on the status of the bacterial ecology and change in bacterial resistance to various antibiotics.
