OBJECTIVETo explore the clinical roles of Jiawei Shentong Zhuyu Decoction (JSZD) in preventing the occurrence of failed back surgery syndrome (FBSS), and to observe its effect on serum tumor necrosis factor-alpha (TNF-alpha).

METHODSTotally 100 patients prepared for surgical operation due to lumbar intervertebral disc herniation were randomly assigned to the treatment group and the control group according to random number table, 50 cases in each group. Patients in the treatment group additionally took JSZD, one dose per day, taken in two portions, once in the morning and once in the evening. Those in the control group took Celecoxib Capsule (200 mg each time, once per day) and Mecobalamin Tablet (0.5 mg each time, 3 times per day). They only took Mecobalamin Tablet from the 11th day. All patients were treated for 30 days. Japanese Orthopaedic Association (JOA) score was performed before treatment, at week 1, after treatment, at 6 months of followed-ups, and at 12 months of followed-ups. And the levels of TNF-alpha in the peripheral blood were observed before treatment and at one month after treatment.

RESULTSTotally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

CONCLUSIONThe application of JSZD was effective for preventing the occurrence of FBSS, and improved the serum TNF-alpha level.

BACKGROUND: Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration (CVVH). Hence blood hemoperfusion with resin adsorption combined CVVH (HP+CVVH) has higher ability of mediator clearance, and can improve clinical outcomes in theory. This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration (HP+CVVH) on plasm cytokines like TNF-α, IL-1β, IL-6, cellular immunity and prognosis in patients with multiple organ dysfunction syndrome (MODS). METHODS: This was a prospective, randomized clinical trial. A total of 30 patients who had been diagnosed with MODS were enrolled in this study. Patients were randomly allocated to routine treatment+HP+CVVH group (treatment group) and routine treatment+only CVVH group (control group). In the treatment group, patients received blood hemoperfusion with resin adsorption for 2 hours, and then received CVVH for 10 hours every day. In the control group, patients received CVVH for 12 hours only every day. The patients in the two groups received blood purification therapy for three days. The plasma of patients in the treatment group was obtained at 0, 2, 12, 24, 26, 36, 48, 50, 60 hours, 5th day, 7th day and 10th day, respectively. The plasma of patients in the control group was obtained at 0, 12, 24, 36, 48, 60 hours, 5th day, 7th day and 10th day, respectively. APACHE II score, T-lymphocytes subpopulations, blood lactate acid concentration, heart rate, breathing rate, and oxygenation index were observed. RESULTS: Plasma cytokines like TNF-α, IL-1β, IL-6 decreased markedly after HP (P<0.01);T-lymphocytes subpopulations CD3+, CD4+, CD8+, CD4+/CD8+ increased after HP+CVVH or only CVVH. The plasma concentrations of TNF-α, IL-1β and IL-6 in the two groups were not markedly different at 12, 36, and 50 hours. But on the 5th day, the plasma concentrations of TNF-α, IL-1β and IL-6 in the treatment group were lower than those in the control group (P<0.05). On the 28th day, 5 patients died in the treatment group, and 6 patients in the control group. CONCLUSIONS: Both HP+CVVH and CVVH can clean plasma cytokines like TNF-α, IL-1β, and IL-6, and improve cellular immunity and clinical symptoms and signs of patients. Compared with only CVVH, the plasma concentrations of TNF-α, IL-1β and IL-6 were lower on the 5th day, and patients have an increased survival rate on the 28 day in the HP+CVVH group.

OBJECTIVETo investigate whether aristolochic acid can be transported into human kidney proximal tubular cell (HKC) and its potential mechanism.

METHODSIntracellular aristolochic acid was measured by liquid chromatography-tandem mass spectrometry. The release of lactate dehydrogenase (LDH) induced by aristolochic acid in the presence of organic anion transporter inhibitor (probenecid) or organic cation transporter inhibitor (tetraethylammonium) was evaluated. The effects of probenecid on aristolochic acid induced connective tissue growth factor (CTGF) mRNA and protein expression were also examined by real time polymerase chain reaction and Western blot, respectively.

RESULTSAristolochic acid was detected in the suspension of the denatured HKC after incubation with aristolochic acid sodium salt. The release of LDH from HKC, which was induced by 60 mg/L aristolochic acid sodium salt, was significantly inhibited by 1 mmol/L probenecid (P < 0.01), but not by 1 mmol/L tetraethylammonium. The increased CTGF mRNA and protein expression in HKC stimulated by 40 mg/L aristolochic acid sodium salt was significantly down-regulated by 1 mmol/L probenecid (P < 0.05), with an inhibition rate of 16% and 21%, respectively.

CONCLUSIONAristolochic acid can be transported into HKC by organic anion transport system, and then exerts its biological effects.

OBJECTIVETo investigate the antagonizing effect of Hirsutella sinensis (HS) on renal tubular epithelial-myofibroblast transdifferentiation (TEMT) and its possible pathogenic mechanism in rats with chronic aristolochic acid nephropathy (CAAN).

METHODSEighteen male Sprague-Dawley rats were equally divided into 3 groups, the model (M) group, the intervention (I) group and the control (C) group. The 24 h urinary protein (UP) in rats was measured before intervention and at the end of the 1st, 4th, 8th, and 12th week, and creatinine clearance rate (CCr) was measured before intervention and at the end of the 12th week respectively. All rats were sacrificed at the end of the 12th week, their kidney was taken for examining the degree of fibrosis in renal interstitial with Masson's stain and determining mRNA and protein expressions of transforming growth factor-beta1 (TGF-beta1), Snail, alpha-smooth muscle actin (alpha-SMA) and cytokeratin in renal tissue by Real-time RT-PCR and immunohistochemistry staining, respectively.

RESULTSCompared with the C group, CCr was significantly lower, while 24 h UP was higher; the relative area of interstitial fibrosis was significantly larger in the M group; besides, the mRNA and protein expressions of TGF-beta1, Snail and alpha-SMA were significantly up-regulated (P < 0.01 or P < 0.05), and those of cytokeratin were significantly down-regulated (P < 0.01) in renal tissue of the M group. While in the I group, all the above-mentioned abnormalities were restored to some extent (P < 0.05) and showed significant difference (all P < 0.05) as compared with those in the M group.

CONCLUSIONHS can downregulate TGF-beta1 and Snail expressions in renal tissue, antagonize TEMT and renal interstitial fibrosis, and improve renal function in CAAN rats.

Objective To determine effect of endurance training on the expression of fatty acid translocase FAT/ CD36 in skeletal muscle of rats and the correlation between the expression and insulin sensitivity index (ISI). Methods Male Sprague-Dawley rats were randomly assigned to two groups:training group(T,n=13) and control group (C, n=10). Rats in group T were trained on treadmill six days a week for 7 weeks. Fat pads around testes and kidneys were weighted for calculating the percentage of fat pads vs body weight. Serum total cholesterol (TC), triglyceride (TG),nonesterified fatty acids(NEFA) and fasting insulin(FINS) were measured. Western blot was used to detect FAT/ CD36 protein expression in quadriceps homogenate. The relation of FAT/CD36 expression to the ISI was analyzed. Results Markedly lower body weight,percentage of fat pads, TC,NEFA, and FINS were seen in group T after 7-week endurance training comparing to that in group C(P<0.01 ,P<0.01 ,P<0.01 ,P<0.05,and P<0.05,respectively). The FAT/CD36 protein expression and ISI were significantly higher in group T than in group C(P<0.01and P<0.05). A significant correlation between FAT/CD36 and ISI were found in group T(r=0.823,P<0.01 ),nut not in group C. Conclusion Seven-week endurance training improved insulin sensitivity and up-regulated the expression of FAT/CD36 for adapting the requirement of fatty acid transportation in skeletal muscle induced by enhanced lipid catabolism after endurance exercise.

BACKGROUND:The majority of studies focus on the lesions of spinal cord injury, while little evidence is available on the change of morphology and structure of distal nerve, muscle and motor endplates fol owing spinal cord injury.
OBJECTIVE:To investigate the time window change of the morphology of motor neurons and skeletal muscles caudal to the lesion after spinal cord injury in rats.
METHODS:Fifty healthy adult Sprague-Dawley rats were randomly divided into three groups:control group (n=5;without treatment), sham operation group (n=10), and spinal cord injury group (n=35). The sham operated rats only received laminectomy. In the spinal cord injury group, rats were subject to complete T 10 spinal cord injury by total laminectomy and cord transverse resection. Then the morphological change including sciatic nerve, motor endplate and median gastrocnemius was observed for each group at 1, 2, 4, 12, 24 weeks after injury.
RESULTS AND CONCLUSION:(1) The myelin sheath layers of sciatic nerve were separated partial y at 4 weeks in rats with spinal cord injury, the myelin sheaths were fragmented with the regeneration of thin-myelinated and unmyelinated axons at 12 weeks. There was a decrease in myelinated axons and an increase in thin-myelinated and unmyelinated axons at 24 weeks. (2) The synaptic gutters of motor endplate, the presynaptic and postsynaptic membrane and synaptic space were distinct at 4 weeks in rats with spinal cord injury, the degenerated motor endplates coexsisted with the intact ones at 12 weeks. The motor endplate disappeared at 24 weeks. (3) There was a slight decrease in muscle cross-sectional area at 2 weeks in rats with spinal cord injury, but no structural change was found, the membrane of myocytes was partial y weakened at 4 weeks, the border of myocytes was obscure with hyperplasia of connective tissue at 12 weeks, and myocytes gathered and in fusion at 24 weeks. As natural history of completely transected spinal cord injury in rats, there were significant changes in morphology of peripheral nerve, motor endplate and skeletal muscles caudal to the lesion at 12 weeks, and the changes were destructive at 24 weeks.

Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.
