Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.

OBJECTIVESeizure is a common emergency in children with complicated pathogeny. Seizures are usually caused by complicated etiology and fever and febrile seizure are the commonest causes. Repeated and permanent seizures can damage the brain. So it is important to take active and effective measures to control seizure and high fever. Because most seizures and fever take place at home or out of hospital and it is difficult to administer drugs intravenously, it is important to explore an easy, safe, quick and effective way to control and prevent both seizure and fever. The present study aimed to explore the efficacy and safety of rectal administration of mixed ibuprofen and diazepam (IBU-DZP) solution.

METHODS(1) Animal study on the pharmacokinetics in rabbits and pharmacodynamics in rats after rectal administration with the mixed solution and on the irritability of the mixed solution to rectum. (2) Clinical study: Pharmacokinetics of the mixed solution in children after rectal administration were investigated.

RESULTS(1) Animal study: IBU and DZP were both rapidly absorbed from rectum with a peak blood level of (11.7 +/- 1.2) min and (9.4 +/- 2.7) min in rabbits, respectively. The mixed solution could effectively prevent the severity of seizures induced by pentetrazole and significantly suppressed fever induced by yeast. There were no remarkable pathological changes in rectal tissues after repeated rectal administration of the mixed solution. (2) Clinical study: IBU and DZP rapidly reached their peak blood levels at about 30 min and 15 min respectively after rectal administration to the children. The peak values were (57.8 +/- 7.9) mg/L and (450.1 +/- 158.7) microg/L, respectively. In fact, both of them reached levels that were much higher than their therapeutic levels in serum just at 5 min after administration, their blood levels were (41.4 +/- 5.5) mg/L and (321.8 +/- 53.9) microg/L, respectively.

CONCLUSIONSIBU-DZP mixed solution administered rectally is an easy, safe, quick and effective way to control and prevent both seizure and fever.

OBJECTIVETo explore the feasibility of evaluating complete ischemia-reperfusion injury (IRI) of the testis by contrast-enhanced ultrasonography with microbubbles (MB) targeted to P-selectin (MBp) in rabbits.

METHODSWe randomly divided 30 healthy adult rabbits into five groups of equal number (control, 0.5 h IRI, 1 h IRI, 2 h IRI, and 4 h IRI), prepared phospholipid MB and MBp, and performed contrast-enhanced ultrasonography of the bilateral testes with MB or MBp at an interval of 20 min at different times after IRI. When MB or MBp disappeared completely in the healthy testis at 4 to 5 min after intravenous injection, we recorded the power of the first frame (F-P) in the IRI testes followed by immunohistochemical staining of the testis tissue.

RESULTSCEU with MBp achieved a significantly higher F-P than that with MB in all the IRI groups (P < 0.05), which was (8.34 +/- 1.20) versus (1.87 +/- 0.25) 10(-5) AU at 2 hours, but there was no significant difference between MB and MBp in the control rabbits (0 AU, P > 0.05). Immunohistochemistry showed a significantly time-dependent increase in the expression of P-selectin in the vascular endothelial cells of the IRI testes, but not in those of the control.

CONCLUSIONContrast-enhanced ultrasonography with MBp can be used to evaluate the inflammatory reaction of testicular ischemia-reperfusion injury.

The aim of this study was to detect the rate of T-helper (Th)17 cells and interleukin (IL)-17 level in peripheral blood of patients with primary immune thrombocytopenia (ITP) and to explore their clinical significance. The proportion of Th17 cells from 48 patients with ITP and 28 healthy controls was detected by flow cytometry, and the IL-17 level was evaluated by enzyme-linked immunosorbent assay (ELISA). The results showed that the percentage of Th17 cells in ITP group was (1.40 ± 1.35)%, which was significantly higher than that in healthy control group (P < 0.05), but in the glucocorticoid hormone-treated group it was significantly lower than that in treated group without glucocorticoid hormone(P < 0.05). The level of IL-17 expressed by Th17 cells in ITP patients was (19.624 ± 5.187) pg/ml, which was higher than that in the healthy control group (P < 0.05), it was lower in the glucocorticoid hormone treated group than that in treated group without glucocorticoid hormone, but there was no statistically significant difference between the glucocorticoid treated and treated group without glucocorticoid hormone (P > 0.05). It is concluded that the Th17 cells may involve in the pathogenesis of ITP, and the glucocorticoid hormone probably plays a therapeutic role through inhibiting Th17 cells.
