OBJECTIVETo find out a method which can assess the prognosis of patients with Acute Organophosphate Poisoning objectively and increase the successful ratio of treatment by investigating relevant factors on the prognosis of the patients with Acute Organophosphate Poisoning.
METHODSWe retrospected 116 patients with Acute Organophosphate Poisoning who were treated in our hospital's emergency room from April 2006 to March 2014. According to the outcome of patients, we distributed the patients to death group and survival group, compared the clinic data and using multivariate analysis with Logistic regression to prognosis factors.
RESULTS116 cases of acute organophosphate poisoning patients died in 23 cases, improved in 93 cases. Death group patients' APACHE-II score are higher than whose in the survival group (P < 0.05). Compared with the survival group, patients' body temperature, blood pressure, pH, GCS index were lower in the death group (P < 0.05) and Cr, WBC, ALT, AST, CK-MB, blood glucose, blood lactic acid, heart rate were higher in the death group (P < 0.05), there were significant difference between two groups with statistical.Low blood pressure, lower GCS score, hyperglycemia and high white blood cell count, were independent risk factors of poor prognosis, and hypotension was maximum value of all the factor (OR = 54.22).
CONCLUSIONAPACHE II prognostic scoring system can be accurately response, vital signs, white blood cell count, pH, serum creatinine, GCS score and serum sodium value which in this system may be associated with prognosis. To evaluate the severity and prognosis of illness Blood glucose, ALT, AST, CK-MB's rising also has certain value.

Objective To investigate the effect of Xuebijing on paraquat-induced oxidative stress and inflammation level in human kidney cell line-2 (HK-2) cells. Methods The HK-2 cells were routinely cultured and divided into blank control group, paraquat poisoning model group, Xuebijing injection pretreatment group and Xuebijing control group according to random number table method. The concentration of paraquat in HK-2 cells were measured by high performance liquid chromatography (HPLC); the activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) were measured by chemical colorimetry method; the levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected by enzyme linked immunosorbent assay (ELISA). Results With prolonged treatment, paraquat concentration gradually increased in HK-2 cells in the paraquat poisoning model group and the Xuebijing injection pretreatment group, reaching the peak value after treatment for 48 hours, moreover, the concentration of paraquat in HK-2 in the Xuebijing injection pretreatment group was significantly lower than that in the paraquat poisoning model group (mg/L: 4.26±0.20 vs. 5.77±0.18, P < 0.05). Compared with the blank control group, the contents of MDA, TNF-α and IL-6 of paraquat poisoning model group were obviously elevated [MDA (nmol/mg): 4.47±0.10 vs. 2.21±0.08, TNF-α (ng/L): 206.91±13.22 vs. 98.14±5.67, IL-6 (ng/L): 253.33±5.22 vs. 116.97±13.54, all P <0.05], and the activity of SOD was significantly reduced (U/mg: 33.30±0.62 vs. 41.58±0.17, P < 0.05). Compared with paraquat poisoning model group, the contents of MDA, TNF-α and IL-6 in Xuebijing injection pretreatment group were obviously decreased [MDA (nmol/mg): 2.92±0.17 vs. 4.47±0.10, TNF-α (ng/L): 166.29±15.47 vs. 206.91±13.22, IL-6 (ng/L): 209.39±3.18 vs. 253.33±5.22, all P < 0.05], and the activity of SOD was significantly increased (U/mg:38.10±0.67 vs. 33.30±0.62, P < 0.05) in the paraquat pretreatment group. Conclusion Xuebijing could reduce the concentration of paraquat in HK-2 cells, and decrease oxidative stress and inflammation factor levels in HK-2 cells.

Objective To compare the biomechanical characteristics of lower limbs of young people with different body mass index (BMI) before and after the intervention of Baduanjin exercise, so as to provide references for scientific exercise and sport prescription for young Baduanjin practitioners with different BMIs. Methods Young volunteers with different BMI were divided into standard group, overweight group and obesity group. The BTS SMART 3D infrared motion capture system was used to capture the motion parameters and electromyography (EMG) parameters, the KISTLER dynamometer was used to collect the dynamic parameters, the AnyBody simulation software was used to calculate the kinematic parameters and dynamic parameters, and BTS SMART Analyzer was used to compare the different integral electromyography values. Results There was no significant difference in each parameter before the intervention of Baduanjin. After the intervention, the angle and angular velocity of the knee joint during extension and flexion in standard group, overweight group and obesity group, and the angular acceleration of the knee joint during extension and flexion in standard group significantly increased. Baduanjin significantly increased the knee flexion force and moment in standard group, overweight group and obesity group, and increased the hip flexion force and moment as well as ankle metatarsal flexion force and moment in standard group. Compared with obesity group, the knee flexion force and moment in standard group were significantly different. The knee joint force and moment were positively correlated with BMI. Baduanjin significantly increased muscle strength of iliopsoas, gluteus medius, piriformis, gluteus maximus, rectus femoris, sartorius, tibialis anterior, biceps femoris longhead, flexor digitorum longus, flexor pollicis longus, musculus peroneus longus and musculus peroneus brevis. Baduanjin significantly increased the integrated electromyogram (iEMG) of rectus femoris, tibialis anterior, biceps femoris. Conclusions Baduanjin can improve muscle strength and neuromuscular control ability of young people. The larger the BMI, the greater the flexion force and moment of the knee joint.
