Objective To compare the effects of Baimai ointment and baclofen in stroke patients with spas-ticity.Methods 84 cases accompanied by limb spasticity in stroke patients by digital table were randomly divided into Baimai ointment group and baclofen group,42 cases in each group.The Baimai ointment group were treated with Baimai ointment on the spastic limbs,the baclofen group received oral baclofen tablets 30 -75mg/days for 2 weeks, 4 weeks,8 weeks.The curative effects of the two groups were compared before and after treatment.Results Before and after treatment in the two groups,the levels of spasticity,pain and activities of daily living (ADL)differences were statistically significant and Baimai ointment in the treatment of spasm.After 4 weeks and 8 weeks,the Ashworth score of the Baimai ointment group were (1.59 ±0.46)points,(0.89 ±0.56)points,and those of baclofen group were (1.75 ±0.64)points,(1.45 ±0.48)points,the differences were statistically significant(t values were 2.916, 3.367,all P <0.05).After 2 weeks,4 weeks and 8 weeks,the VAS score of the Baimai ointment group were (2.72 ± 0.54)points,(2.02 ±0.24)points,(1.24 ±0.12)points,and baclofen group were (3.56 ±0.44)points,(3.15 ± 0.48)points,(2.58 ±0.26)points,the differences were statistically significant(t values were 2.975,3.359,5.416, all P <0.05),activities of daily living (ADL)was higher than that of the baclofen group.After 8 weeks,the MBI score of the Baimai ointment group was (64.46 ±10.78)points,and baclofen group was (50.74 ±9.18)points,the difference was statistically significant between the two groups (t values was 3.562,P <0.05).Conclusion Baimai ointment has the better antispasmodic effect than baclofen in patients with stroke.

Aim To investigate the effects of metformin on phospho-signal transducers and activators of transcription 3(p-STAT3) expression in the spinal dorsal horn in rats with bone cancer pain(BCP).Methods Healthy female SD rats weighing 200~220 g were randomly divided into four groups(n=12 each): Sham+NS, Sham+Metformin, BCP+NS, BCP+Metformin groups.Normal saline or metformin(200 mg·kg-1) was given intraperitoneally once a day at 7~14 day after surgery in four groups.Mechanical withdrawal threshold(MWT) was measured on-1, 3, 5, 7, 10, 12, 14 day after BCP.The L4-6 segments of spinal cords were used to detect the expression of p-STAT3 by Western blot and immunohistochemical staining technique after the behavioral test was completed on day 14.Results Intraperitoneal injection of metformin reversed hyperalgesia and suppressed the expression of p-STAT3 in BCP rats.Conclusion Metformin can attenuate BCP by inhibiting the expression of p-STAT3 in the spinal dorsal horn.

Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

Objective Hypoxic-ischemic brain damage (HIBD) is a life-threatening neonatal disease during perinatal stage. Since excitatory amino acids (EAAs) and their receptors are involved in the pathogenesis. Sodium hydroxybutyrate ( r-OH ), an intermediate metabolite of GABA, may have beneficial effects on HIBD. Methods One-hundred seven-day (7d) SD rat pups were randomly assigned to one of three groups:(Ⅰ) control group (n= 20);(Ⅱ) sham operation group (n=20)and (Ⅲ) r-OH group which was further divided into 3 subgroups according to the dose of r-OH 50 mg?kg-1 (r-OH1) (n=20),100 mg?kg-1 (r-OH2) (n=20),200mg?kg-1 (r-OH3) ( n=20).Animals in control group and r-OH group were subjected to left carotid artery ligation followed by 2 h of hypoxia (O2 :N2=8%:92%).Normal saline ( NS) was administered ip immediately after sham operation or hypoxia,then 3 times a day for 7 days in group Ⅰ and Ⅱ.In r-OH group r-OH was administered ip instead of NS. Brain damage was evaluated by survival rate, pathology, the ratio of weight of left to right hemisphere on the 28 th day after ischemia-hypoxia and the capacity of learning and memory using Y-Maze test. Results (1) The survival rate on the 28 th day after hypoxia or sham operation was significant lower in control group (60%) than that in the other groups (85%-95% ) (P
