Conclusion: Caffeine and the combination of caffeine and placebo expectation can increase alertness.

Objective To evaluate the effects of 131I treatment for Graves hyperthyroidism patients with leucopenia and the alteration of WBC levels after treatment.Methods A total of 257 Graves hyperthyroidism cases were retrospectively studied after 131I treatment.Based on baseline WBC count,119 cases with WBC count ＜4.0 × 109/L before 131I treatment were diagnosed with leucopenia and 138 cases had normal WBC.There were no significant differences in age,weight of thyroid,131I uptake rate in 24 h,dose of 131I and course of the disease between the two groups (all t ＜ 0.972,all P ＞ 0.05).WBC,lymphocyte,neutrophil and platelet counts were recorded before and 1,3,6 and 12 months after 131I therapy.The therapeutic effects were graded as clinical cure,improvement,invalidation and hypothyroidism.Statistical analyses,including independent samples t test,x2 test and one-way analysis of variance,were performed using SPSS 13.0.Results The WBC levels in the leucopenia group were (3.49 ± 0.43) × 109/L,(4.06 ±0.98) × 109/L,(4.20 ±1.04) × 109/L,(4.37 ±0.93) × 109/L and (4.88 ± 1.20) × 109/L before 131I treatment and 1,3,6,12 months after 131I treatment,respectively; while,those in the normal WBC group were (5.70 ± 1.08) × 109/L,(5.50 ± 1.14) × 109/L,(5.74 ±0.99) × 109/L,(5.95 ± 1.14) × 109/L and (6.07 ± 1.17) × 109/L,respectively.There was no statistically significant difference of WBC levels before and 1 month after 131 I treatment (t =1.662,P ＞ 0.05) in the normal WBC group,but WBC levels at those timepoints were significantly different in the leucopenia group (t =3.816,P ＜ 0.05).In the leucopenia group,there was no significant change of lymphocytes before and after 131I treatment,while the average neutrophil count showed an increasing trend during the 1,3,6 and 12 months after 131I treatment (F =40.583,t:1.468-11.264,all P ＜ 0.05).The average platelet counts at 6 and 12 months after 131I treatment were (187.80 ± 36.03) × 109/L and (206.88 ± 26.04) × 109/L respectively,which were higher than that before 131I treatment (F =9.735,t =2.604,4.892,all P ＜0.05).In the normal WBC group,there were no statistical differences of WBC changes before and after 131I treatment except for a lower lymphocyte count at 1 month after 131I treatment than that at baseline ((1.79 ± 0.37) × 109/L vs (1.99 ±0.63) × 109/L;F =12.868,t =3.284,both P ＜ 0.05).The treatment effects of the two groups were not significantly different (x2 =0.739,P ＞ 0.05).Conclusions 131I treatment presents similar therapeutic effects on Graves hyperthyroidism patients with leucopenia and those with normal WBC levels.WBC levels in patients with leucopenia may recover to baseline during the post-treatment follow-up.Thus 131I treatment is a safe and effective method for Graves hyperthyroidism patients with leucopenia.

BACKGROUND:Indian hedgehog homolog (Ihh) protein and its signal protein Gli1, as wel as Runt related transcription factor 2 (Runx2) are closely related to the pathogenesis of osteoarthritis. The increased expression of these factors is one of the major causes of degenerative joint changes.
OBJECTIVE:To explore the roles of Ihh, Gli1 and Runx2 in the development of osteoarthritis.
METHODS:Thirty Sprague-Dawley rats were randomly divided into two groups:control group (n=10) and model group (n=20). In the model group, rats received unilateral anterior cruciate ligament transection, to establish osteoarthritis model. Ten experimental rats were kil ed at 4 and 12 weeks after surgery respectively. Another 10 rats received unilateral knee arthrotomy as pseudo-operation controls and 10 pseudo-operation rats were kil ed at 12 weeks after surgery.
RESULTS AND CONCLUSION:In the model group, cartilage degeneration was obvious at 4 weeks and became severer at 12 weeks after anterior cruciate ligament transection operation. Expression levels of Ihh, Gli1 and Runx2 in the cartilage were increased significantly at 4 weeks after operation, but decreased at 12 weeks after operation. Experimental findings indicate that Ihh, Gli1 and Runx2 play important roles in the development of osteoarthritis, and their expression levels are significantly increased at early stage of osteoarthritis, which can be regarded as the indicators in the prophylaxis and treatment research of osteoarthritis.

Objective To study the pharmacokinetic features of silibinin from Jiqi Injection(JI) in Beagle dogs,and to observe the effect of Panax notoginseng saponins,another active component in JI,on pharmacokinetics of silibinin. Methods The Beagle dogs received intravenous injection of JI and silibinin,and then its plasma sample was collected in different time. The plasma samples of Beagle were prepared by hydrolysis with sulfatase-? glucuronidase complex enzyme and liquid-liquid extraction with aether. A high-performance liquid chromatographic method was developed to determine the plasma concentration of silibinin,and the pharmacokinetic parameters were performed by BAPP2.3 program. Results The pharmacokinetics of two tested preparations met with two-compartment model. There were not significant differences between pharmacokinetic parameters of JI and that of Silibinin Injection. Conclusion The silibinin in Jiqi Injection has a fast in-vivo clearance rate after intravenous injection,and Panax notoginseng saponins have no effect on its pharmacokinetic parameters.

Objective To explore the optimal time for clinical interventions on full-term or nearterm pregnant women with premature rupture of membranes(PROM). Methods A retrospective study was conducted on clinical data of 903 healthy, full-term or near-term (gestational age ≥ 35 weeks), singleton pregnant women with PROM, who admitted to our hospital from January 1, 2005 to December 31, 2009. All subjects were divided into 6 groups: women in group 1 were those fell into spontaneous labor within 6 h after PROM (n=269, 29.8%); women in group 2 were in spontaneous labor between 6 to 12 h after PROM (n= 161, 17.8%) ; women in group 3 were in spontaneous labor at 12 to 24 h after PROM (n = 75, 8. 3%); In group 4 oxytocin was administered for induction for women not in labor at 6 to 12 h after PROM (n= 124, 13.7%) ; Group 5 included those women who were not in labor at 12 to 24 h after PROM and oxytocin induction was offered (n=98, 10. 9%);Group 6 consisted of those women who were not in labor over 24 h after PROM and oxytocin induction was offered (n = 176, 19. 5%). The maternal and neonatal complications and outcomes of all pregnancies were reviewed and compared. Results Among the 903 cases, the total number of women without any medical interventions was 681, among which 505 (74.2%) fell into spontaneous labor, including 430 (63.2%) within 12 h with a cesarean section rate(CSR) of 20.7%(89/430), 75 (11.0%) at 12-24 h after PROM with the CSR of 50.7% (38/75), and 176 (25.8%) did not go into labor spontaneously (group 6) with a CSR of 70. 5% (124/176). (2) Among the 930 women, 398were induced at 6, 12 and 24 h after PROM. The CSR, incidence of intrauterine infection, puerperal morbidity and perinatal mortality rate in group 5 were significantly lower than those of group 6 [CSR:52.0%(51/98) vs 70. 5%(124/176); intrauterine infection: 6. 1%(6/98) vs 22. 7%(40/176);puerperal morbidity: 6. 1% (6/98) vs 19.9% (35/176); perinatal mortality: 7. 1% (7/98) vs 20.5%(36/176),all P＜0. 01], but no difference was found in the incidence of postpartum hemorrhage [1.0%(1/98) vs 4.0%(7/176), P＞0.05]. Conclusions Intervention is not recommended within 12 h after PROM in full term or near term gravidas. However, induction of labor should be offered thereafter. However, the CSR and incidence of maternal and neonatal complications rise up if induction of labor postponed to 24 h after PROM.

Objective To design a new animal model for end-to-side anastomosis of peripheral nerves and analyze the efficiency. Methods The experiment involved 28 Wistar rats,of which the left legs were set as experimental group and the right ones as control group based on mode of nerve anastomosis.In experimental group,the tibial nerves were cut off for anastomosis of the proximal end of the tibial nerves with the distolateral side of the common peroneal nerve.While in control group,the common peroneal nerves were cut off to anostmose the distal end of the peroneal nerve with the distolateral side of the tibial nerves.Electrophysiological examination was done three months later to observe and compare wave amplitude,latent period and maximal wave amplitude at set stimulus volume in both groups and compare the fiber number at distal and proximal ends of the common peroneal nerves. Results There was no significant statistical difference in regard of amplitude,latent period and maximal wave amplitude in both groups.However,the fiber number at distal end of the stoma was much more than that at proximal end in the experimental group,with statistical difference(P
