AIM: To investigate the clinical effect of compound anisodine on patients with paralytic strabismus and the influence on malondialdehyde ( MDA ) and superoxide dismutase ( SOD) .
●METHODS: Seventy cases diagnosed with paralytic strabismus from Jun. 2008 to Dec. 2014 were selected as treatment group; another 70 cases with paralytic strabismus from Oct. 2000 to Jan. 2008 were chosen as control group. The control group was given with conventional therapy, and treatment group was additionally injected with compound anisodine subcutaneously on the basis of the control group. Treatment lasted for two courses about 28days. The effect of compound anisodine on patients with paralytic strabismus was evaluated and the serum level of MDA and SOD was also measured before and after treatment.
●RESULTS: ln treatment group, 54 cases were cured (77%), 14 cases improved (20%) and 2 cases had no response ( 3%) and total efficiency reached to 97%. ln control group, 32 cases were cured ( 46%) , 21 cases improved ( 30%) and 17 cases had no response ( 24%) and total efficiency was 76%. The cure rate and total efficiency of treatment group were significantly higher than that of control group (P<0. 05). Before treatment, the level of SOD and MDA was equal in two groups. After treatment, increased SOD level and decreased MDA level was observed in both groups. However, compound anisodine were significantly increased SOD level and reduced MDA level when compared with conventional therapy (P<0. 05).
●CONCLUSION: The compound anisodine shows the beneficial effect on patients with paralytic strabismus. Compound anisodine may exert the effect via increasing SOD and reducing MDA.

ObjectiveTo investigate the mechanism of protective effect of Xuebijing injection on vascular endothelial cells in rats with heat stress.Methods Ninety Sprague-Dawley(SD) rats were randomly divided into control, model and Xuebijing injection treatment groups, 30 rats in each group. Heat stress model was reproduced by placing rats in constant temperature box at 40℃, 60% relative humidity for 1 hour, Xuebijing injection group was treated by intraperitoneal injection of Xuebijing 2.5 g/kg, while the control and model groups were treated by intraperitoneal injection of normal saline 2 mL/kg, once a day only in 1 day for both groups. After model establishment, the rectum temperature, heart rate and the mean arterial pressure(MAP) were recorded at 2, 6, 12 hours in each group. At the same time, the rat abdominal aortic blood was collected and serum was separated, the enzyme-linked immunosorbent assay(ELISA) was used to determine the aortic serum levels of lipopolysaccharide(LPS), nuclear factor-κB(NF-κB) and p53, and the prothrombin time(PT), activated partial thromboplastin time(APTT) and D-dimer of venous blood were detected by automatic blood coagulation analyzer(ACLTOP).Results Compared with those in control group, the rectum temperature, heart rate, LPS, NF-κB, p53, PT, APTT, D-dimer were significantly increased, and MAP was obviously decreased in model group(P<0.05 orP<0.01). Compared with model group, the above indexes were improved significantly in Xuebijing injection treatment group at 2 hours〔rectum temperature(℃): 38.02±0.22 vs. 39.32±0.33, heart rate(bpm): 507±14 vs. 562±35, MAP(mmHg, 1 mmHg=0.133 kPa): 98±6 vs. 87±13, LPS(ng/L): 0.65±0.03 vs. 0.82±0.05, NF-κB(ng/L): 1.10±0.04 vs. 1.33±0.05, p53(ng/L): 1.33±0.03 vs. 1.73±0.02, PT(s):15.47±1.03 vs. 20.28±2.01, APTT(s): 40.26±2.46 vs. 47.46±3.51, D-dimer(μg/L): 238.54±8.32 vs. 323.12±8.14,P<0.05 orP<0.01〕.Conclusion Xuebijing injection can correct the disorders of blood PT, APTT, D-dimer via decreasing the secretion of the levels of NF-κB, p53 from vascular endothelial cells in rats with heat stress, thus the integrity of the vascular endothelium can be protected, and LPS entering into the blood stream can be inhibited.

Objective To explore the effectiveness of ω-3 fatty acids in intervening rat models of chronic obstructive pulmonery disease (COPD).Methods The rat COPD models were established by cigarette smoking and intratracheal lipopolysaccharide instillation.Totally 90 rats were randomly divided into 3 groups:normal control group (treated with normal saline),COPD group,and intervention group (the COPD rat models treated with ω-3 fatty acids).Lung tissues were obtained on the 7th,21st,and 28th day.The left lower lobes were analyzed to determine the expressions of nuclear factor-kappa beta (NF-κB) and interferon-γ (IFN-γ)and the right lung lobes were sliced for detecting the cell apoptosis.Double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was used to detect the serum IFN-γ and interleukin-6 (IL-6).Results (1) The pathological changes of lung tissue:there were a large number of inflammatory exudation,alveolar wall thickening,hyperplasia of vascular smooth muscle and the alveolar structure destruction in the COPD model group,but the lung tissue were part of alveolar cavity and a little inflammatory exudate in ω-3 fatty fish acids treatment group,control rats were almost no alveolar inflammation on the 28th days.(2) On the 28th day,NF-κB protein expression of the lung tissue (18.91 ± 3.07) in rats of COPD model group was significantly higher than the control group and the intervention group (5.47 ±4.86 and 7.23 ±2.21) (P ＜0.01).On the 28th day,IFN-γ protein expression in lung tissue of the rats in the model group was 7.12 ±3.37,significantly lower than the intervention group (18.74 ± 2.65),the difference was statistically significant (P ＜ 0.01).(3) The IL-6 levels of the blood-serum of model group rats were (13.43 ± 2.47) ng/L,significantly higher than the control group and the intervention group [(4.78 ± 1.93) and (4.98 ± 1.89) ng/L],the differences were statistically significant (P ＜ 0.01) on the 28th day,,but the IFN-γ level [(2.23 ± 0.63) ng/L] in COPD group was more poorer than ω-3 fatty acids group and the intervention group [(4.51 ± 0.71) and (7.05 ± 0.52) ng/L] (P ＜ 0.01).Conclusions The ω-3 fatty acids can lower NF-κB protein expressions in lung tissues and serum and IL-6 levels in COPD rats; aslo,it can increase the IFN-γ protein expression in lung tissue and serum.Thus,it can prevent the lung inflammation in COPD rats.

Objective To investigate the changes of cerebral blood flow and the level of brain injury in a rat model of deep hypothermia low flow(DHLF).Methods Twelve SD rats aged 3 weeks were randomly divided into sham group and model group.Regional cerebral blood flow(rCBF)of all rats was measured continuously during the operation by laser Doppler flowmetry,and the changes of rCBF were measured before temperature decreased,when the temperature decreased to(21.0±0.5)℃,0-5 minutes,25-30 minutes,55-60 minutes,115-120 minutes during DHLF and 0-5 minutes after DHLF operation.Another 60 SD rats aged 3 weeks were randomly divided into sham group and model group.Six rats of each group were sacrificed at 1,6,24,72 hours and 7 days after DHLF operation to detect the pathological changes of the brain and the neuronal apoptosis by HE staining and TUNEL assay.The neurological deficit score(NDS)was recorded at 24,72 hours and 7 days after operation for evaluating the neurologic functional outcome.ResultsWhen the temperature was decreased to(21.0±0.5)℃,the levels of rCBF of sham group and model group were significantly decreased to(41.1±4.2)% and(40.7±3.4)% of the baseline value,and the rCBF level of model group was further decreased to(15.7±3.5)% of the baseline value 0-15 minutes during DHLF(P ＜ 0.01),with no obvious changes in all the time intervals during DHLF.Compared with the sham group,the scores of NDS of model group were significant lower at 24 and 72 hours after operation(P ＜ 0.05 or 0.01).Besides,a significant pathological change of the brain tissue and a increased percentage of TUNEL-positive staining cells were observed in model group at 6,24,72 hours and 7 days after operation(P ＜ 0.01).Conclusions Rat model of DHLF is an ideal and reliable model of brain injury,for it is similar to DHLF procedure of clinical cardiac operation.

Objective To determine the level and clinical significance of 5-hydroxytryptamine (5-HT) and intestinal fatty acid binding protein (iFABP) in patients of severe acute pancreatitis (SAP) with intestinal dysfunction. Methods The serum and urine in 42 cases of SAP with intestinal dysfunction were collected at day 1, 3 and 7 after admission, respectively. The numbers of bowel sounds were recorded. 20 health subjects were selected as the control. Results The numbers of bowel sounds in health subjects were 5.6 ± 2.3/min. The numbers of bowel sounds in SAP patients at day 1,3 and 7 were 2.3 ± 0.7/min, 1.7 ± 0.2/min and 3.1 ± 1.1/min, respectively;which were significantly lower than that in the control group (P < 0.01). The level of 5-HT in the control group was(86.7 ± 9.5)ng/ml, while the levels of 5-HT in the SAP patients at day 1, 3 and 7 were (112.0 ± 17.8) ng/ml, (130.5 ± 19.7) ng/ml, (107.9 ± 16.3) ng/ml. The level of urine iFABP in the control group was (90.5 ± 19.8) pg/ml, while the levels of urine iFABP in the SAP patients were (1250.2 ± 425.3) pg/ml, (1586.9 ± 523.4) pg/ml, (1154.6 ± 394.0) pg/ml. The levels of 5-HT and urine iFABP in the SAP patients all were significantly higher than those in the control group (P <0.01). The levels of 5-HT and urine iFABP in the SAP patients at day 3 were significantly higher than those in the day 1 and day 7, while there was no significant difference between the two groups. Conclusions Determination of serum 5-HT and urine iFABP in patients with early SAP could effectively evaluate the intestinal function, and it may have potential clinical significance.

Objective To investigate the effect of Da-Cheng-Qi decoction on enteric functional disturbance in rats with acute experimental pancreatitis and its potential mechanism. Methods Seventy-two SD rats were randomly divided into sham operation group, acute pancreatitis (AP) group and Da-Cheng-Qi decoction treated group with 24 each. The AP model was induced by retrograde injection of sodium taurocholate (0.1 ml/100 g) into bitiopancreatic duet. Before modeling, the rats in treatment group received Da-Cheng-Qi decoction (2 g/100 g), and the rats in other two groups received 0.9% NaCl solution. The rats were sacrificed at 3, 6 and 12 hours with 8 each, and the blood samples were taken for detecting the level of amylase and the contents of 5-hydroxytryptamine (5-HT) by enzyme-linked immunosorbent assay. The colonic tissues 10 cm apart from trans-ligament incluing jejunum, terminal ileum and sigmoid colon were collected for examining the expressions of 5-HT_3 and 5-HT_4mRNA and proteins by RT-PCR and Western blotting respectively. Results ① The levels of serum amylase and 5-HT in AP group and treatment group were significantly higher than those in sham operation group (P<0. 01), but they were lower in treatment group than in AP group at each time points (P<0. 05). The level of 5-HT was increased in the initial stage and then decreased gradually both in AP group and treatment group. ③ The expressions of 5-HT_3 and 5-HT_4 mRNA and proteins were significantly decreased in the jejunum, terminal ileum and sigmoid colon in AP group compared with sham operation group (P<0. 01). Whereas the expressions of 5-HT_3 mRNA and protein,but not 5-HT_4, were increased in the treatment group in comparison with AP group (P<0.05). Conclusions The level of 5-HT is significantly increased in acute pancreatitis, but its receptors (5-HT_3 and 5-HT_4) are decreased, which may induce enteric functional disturbance. The Da-Cheng-Qi decoction may improve enteric dynamic failure by increasing the expression of 5-HT_4 and may be a choice for treatment of acute pancreatitis with enteric dynamic failure
