Objective To investigate whether electroacupuncture(EA) regulates the pain in New Zealand rabbits with osteo arthritis by inhibiting the IL-17 and IL-17R expression in spinal cord.Methods New Zealand rabbits were randomly divided into the sham operation group,inflammation model group,sham operation+ IL-17 group,inflammation+ IL-17 group,inflammation + EA group and inflammation +sham EA group,8 cases in each group.The rabbit osteoarthritis model was established by using the papaya protease,IL-17 and IL-17 antiserum was injected into the spinal canal,The EA group selected the EA at Zusanli point(30 min,2 Hz continuous wave,1～ 2 mA),the sham EA group adopted the non-acupoint stimulation.Then the pain threshold of rabbits was detected.The mRNA expression of IL-17 and IL-17R in rabbit spinal cord tissue was detected by RT-qPCR and the protein expression was detected by Western-Bolt.Results The rabbit pain threshold was significantly decreased after constructing the New Zealand osteoarthritis model(P＜0.05),and the spinal canal injection of IL-17 could significantly decrease the pain threshold of sham operation New Zealand rabbit(P＜0.05),while the spinal canal injection of IL-17 antiserum could significantly increase the pain threshold of osteoarthritis model rabbit.Selecting EA at Zusanli point could significantly enhance the rabbit pain threshold (P＜0.05).The mRNA and protein expression of IL-17 and IL-17R of the osteoarthritis model group were significantly increased (P＜0.05),while the expressions were significantly decreased after EA stimulation(P＜0.05).Conclusion The pain occurrence of New Zealand rabbit osteoarthritis may involve the IL-17 abnormal expression in spinal cord.EA may regulate the osteoarthritis pain by inhibiting the expression of IL-17 and IL-17R in spinal cord.

The processes of fermentation of corn powder by lactic acid bacteria was studied. The results indicated that, after 39 hours fermentation, the lactic acid content reached 2. 1g/100mL, and some nutrients as oligosc-chrides and amino acids were also produced. The result is of significance to the technological design of producing lactic acid beverage of corn.

This paper was aimed to study the influence ofBu-Shen Hua-TanFang (BSHTF) on the learning and memory function of diabetes mellitus (DM) rats. A total of 50 3-month-old male Wistar rats were randomlydivided into the control group, model group and 3 BSHTF groups (i.e., high-, middle-, and low-dose). A total of 35 mg·kg-1 streptozotocin (STZ) was intraperitoneally injected into the model and BSHT group. The same volume of citric acid-sodium citrate buffer solution was intraperitoneally injected into the control group. The intragastric administration of BSHTF at the dose of 20, 10, and 5 g·kg-1 was given to the BSHTF groups, respectively. The behavior and content of serum 3-deoxyglucosone (3-DG) were detected among DM rats after 30 days. The results showed that the levels of serum glucose in the model group and the BSHTF groups were obviously higher than that of the control group (P < 0.01). The swimming time to platform of rats in the model group was obviously prolonged compared to the control group with significant difference from the second day on (P < 0.01). The required time in different BSHTF intervention groups was obviously decreased compared with the model group from the 4th day (P< 0.05). The level of serum 3-DG in rats of the model group was obviously higher than that of the control group (P < 0.01). The level of serum 3-DG in rats of the middle-dose BSHTF group was obviously decreased compared with the model group (P < 0.05). It was concluded that BSHTF was able to improve the cognitive impairment among DM rats by reducing the levels of serum glucose and serum 3-DG.

Objective To study the effect of sodium hyaluronate(SH) on cornea preservation to provide a basis for eyes banks cornea preservation. Methods SH was applied in the short-term and middle-term cornea preservation. The preservation effect was evaluated by corneal morphology, trypan blue-alizarin red staining, activity assay of SDH and G-6-P enzymes, and ultrastructural observation of corneal endothelium. Results The above indices were obviously better in the experiment group than in the control group (P

Objective To investigate the contribution of hypoxia-inducible factor inhibitor YC-1 to cisplatin chemo-sensitivity to human ovarian cancer cells A2780s in vitro. Methods Ovarian cancer cells were divided into four groups which were treated with saline, YC-1, cisplatin, and YC-1+cisplatin, separately, mRNA of HIF-1αand VEGF in the A2780s cells were detected by real-time fluorescence quantitative PCR by calculating 2-△△CT;the protein were detected by Western blot, to evaluate the change of hypoxia and angiogenesis capabilities under the ovarian cancer microenvironment. Results Compared with the control group, mRNA and protein of HIF-1αand VEGF expressed less in the group of YC-1, cisplatin and YC-1+cisplatin;while, those in the group of YC-1+cisplatin were lower than the monotherapy (P<0. 05), but no significant difference was detected between the YC-1 and cisplatin groups, and the expression of HIF-1αand VEGF mRNA were positively related(r=0. 830 5)in each group. Conclusion YC-1 exerts the antitumor effect and may contribute to sensitivity to cisplatin in the therapy of ovarian cancer.

Objective To study and compare the effects of Fentanyl transdermal pain patches and Pethidine in postoperative analgesia of malignant tumor and its nursing methods.Methods 100 patients with malignant tumor in our hospital from January 2008 to November 2010 were selected as research object,all the patients were randomly divided into group A (Fentanyl transdermal pain patches group) and group B (Pethidine group)with 50 cases in each group,then the VAS score 2,4,8,24 and 48h after the surgery,incidence of adverse reactions,satisfaction rate and serum catecholamine,cortisol,blood glucose before and after the surgery were analyzed and compared,and all the patients were given corresponding nursing measures.Results The VAS score of group A at 2,4,8,24 and 48h after the surgery were all better than those of group B,incidence of adverse reactions was lower than that of group B,satisfaction rate was higher than that of group B,serum catecholamine,cortisol,blood glucose after the surgery were all lower than those of group B,there were significant differences.Conclusions The effects of Fentanyl transdermal pain patches in postoperative analgesia of malignant tumor is stable,and it gets good reputation from the patients,the effects is obvious combined with nursing.
