Chinese Journal of Biochemical Pharmaceutics 2017;37(1):81-83
Objective To investigate the effects of penehyclidine hydrochloride injection combined with safflower injection on TLRs/NF-κB signaling pathway and T cell subsets in mononuclear cells of patients with organophosphorus pesticide poisoning. Methods 80 cases of organophosphate poisoning patients from June 2014 to June 2016 in onglu first people's hospital were selected,randomly divided into control group and observation group, the control group was treated with penehyclidine hydrochloride,observation group were treated with Honghua injection based on the treatment of control group. The effects were compared between two groups of TLRs/NF-κB in peripheral blood mononuclear cells pathway and T cell subsets in peripheral blood, and compared two groups of patients with cholinesterase activity. Results On the third,fifth and 7th day of treatment,cholinesterase activity in both groups was higher than that before treatment,the activity of cholinesterase in the observation group was significantly higher than that in the control group (P<0.05).After treatment,compared with before treatment,the levels of TLR2,TLR4 and NF-κB in the two groups were significantly decreased,and TLR2,TLR4,NF-κB levels in the observation group were lower than those in the control group, the difference was statistically significant (P<0.05),Th17,Th17/Treg levels in the observation group were significantly lower,and lower than the control group,Treg content was significantly higher,and higher than the control group,the difference was statistically significant (P<0.05). Conclusion Penehyclidine hydrochloride injection combined with safflower injection can help to reduce Th17,Th17/Treg levels,increased Treg cell content,regulate the inflammatory response, and promote recovery of cholinesterase activity.

Objective To investigate the effect of ketamine on the phosphodiesterase (PDE) activities in lung tissue and leukocytes in rats. Methods Twenty SD rats weighing 140-160 g were randomly divided into two groups of 10 animals each : (A) ketamine group received intraperitoneal ketamine 10 mgkg-1 and (B) control group received equal volume of normal saline ip. Thirty minutes after ketamine administration the animals were sacrificed by exsanguination. Leukocytes were separated and 25 mg of lung tissue was obtained for determination of PDE activities by HPLC. Results The PDE activities in both lung tissue and leukocytes were lower in ketamine group than those in control group ( P

Objective To observe the level of social support and self-efficacy of the breast cancer patients with postoperative chemotherapy, and study the relationship between them. Methods 76 patients were investigated with Social Support Rating Scale and Strategies Used by Patients to Promote Health (SUPPH). Results The total and every dimension scores of SUPPH and Social Support decreased in the patients. The total and every dimension scores of Social Support positively correlated with every dimension scores of SUPPH (P<0.01). Conclusion The level of self-efficacy and social support may relate each other.

In order to investigate the interactions between first- and second-order motion perception systems, 14 adult subjects with normal or correct to normal visual acuity were recruited and divided into two groups. Then these two groups were trained, in their parafovea, to discriminate the direction of first- and second-order motion gratings respectively. The spatial frequency of the gratings used in study was fixed at 2 cycles/degree and the temporal frequency was fixed at 8 Hz during training. Contrast sensitivity of subjects in these two training groups for first- and second- order motion was measured before and after 7 days' training to estimate the effects of training. In addition, the differences between the two training groups(14 subjects) and another control group (11 subjects) were studied. The results showed that: 1) the training with first-order motion gratings can improve subjects' performance in first-order motion direction discrimination but the improvement can't be transferred to the performance in second-order motion task; 2) the training with second-order motion gratings can improve subjects' performance in both first- and second-order motion direction discrimination tasks. In conclusion, an " asymmetric transfer" occurred between the training effect of first- and second-order motion gratings. These results indicate that there are two mechanisms for perceiving first- and second-order motion respectively. However, they are not completely different from each other but only partly separated.

Objective To evaluate the effect of the distal humerus extremity comminuted fracture treated by double plates through oleeranon osteotomy. Method Twenty-eight patients with humerus extremity comminuted fractures were fixed by double plates through olecranon osteotomy followed by early functional exercise. Results All the cases were followed up 9-31 months. The curative effect was assessed by the method of modified Cassebaum rating system. The operation was excellent in 10 cases, good in 12 cases, fair in 5 cases, bad in 1 case. The excellent and good rate was 78.57%(22/28). Conclusion Treatment of humerus extremity comminuted fractures by double plates through olecranon osteotomy followed by early functional exercise are excellent with satisfactory functional recovery.

Objective In order to understand whether recombinant human growth hormone(r-hGH) can improve the idiopathic short stature(ISS) boys' final adult height(FAH).Methods We measured 16 cases diagnosed as ISS boys FAH, divided into 2 groups, of which 9 cases were not given r-hGH treatment, treatment group ,7 patients received r-hGH treatment, a dose of 0.1 ~ 0.13 U· kg-1·d-1, before going to sleep subcutaneous injection, duration of treatment was 6 ~ 20 months ( 11.9 ± 5.2 months).Results The treatment group compared with the average FAH FAH observation group had significantly improved the average(t =2.219,P<0.05).Conclusion r-hGH can improve the ISS boys FAH, but early treatment, the longer the course the more obvious effects.

Objective To investigate the mechanism of ventricular dilation-induced arrhythmias by dilating isolated rat hearts. Methods Isolated rat hearts were perfused by Langerdorff method. After equilibration, 80 hearts were randomly divided into four groups as follows: (1) control group (n=20), (2) Ca2+ preconditioning (CPC) group (n=20), (3) streptomycin group (n=20), and (4) CPC + streptomycin group (n=20). A latex balloon which can be filled with fluid was anchored in the left ventricle through the left atrium and mitral valve. Epicardial ECG of the left ventricle, left ventricular pressure, coronary flow and heart rate were recorded before and during ventricular dilation by injecting fluid into the latex balloon. The rate and duration of ventricular dilation-induced arrhythmias were recorded. Results Under the same increase in ventricular end-diastolic pressure made by inflation of the balloon, the rate of arrhythmias was 100% and duration of arrhythmias was 2.56±0.46 s in the control group. Both the rates of premature ventricular beat (90 %) and ventricular tachycardia 70 % ) were high. Compared with the control group, the total rate (60 % ) of arrhythmias was lower, and duration (1.67±0.61 s ) of arrhythmias was shorter in the CPC group. Both the rates of premature ventricular beat (60%) and ventricular tachycardia (40%) were low comparatively. The rate of arrhythmias (45 %) was lower and duration ( 1.64±0.42 s)of arrhythmias was shorter, and the rates of premature ventricular beat (30 % ) or ventricular tachycardia (35 %) were lower in the streptomycin group than in the control one. The least ventricular dilation-induced arrhythmias occurred in the CPC + streptomycin group. The rate of arrhythmias (10%) was the lowest and duration (1.01±0.37s) of arrhythmias was the shortest; both the rates of premature ventricular beat (5%) and ventricular tachycardia (10%) were the lowest. Conclusions Ventricular dilation may induce arrhythmias in isolated rat hearts. Stretch-activated ion channel and the increase in [Ca2+]I are supposed to play important roles in the pathological mechanism.
