OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.

METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.

RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.

CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

Objective To summarize the ultrasonic characteristics of urinary calculus in infants who had history of feeding melamine contaminated milk powder.Methods A total of 163 children[aged(19.4?10.9)months] with urolithiasis,who had feeding melamine contaminated milk powder,were retrospectively analyzed using ultrasonography.Twenty children [aged(16.7?9.9)months] with urolit-hiasis,who had no feeding history of melamine contaminated milk powder,were chosen as controls.Ultrasonic characteristics were compared between the 2 groups.Results For melamine calculus cases,sporadic spot or hyperechic mass with different size and shape in the collecting system,partly without acoustic shadow,was found in 65 cases;dense echo and luminous belt with obscured acoustic shadow under a band without echo was found in 48 ureteral calculus cases;irregular strong echo mass or small spot with thick acoustic shadows without side lobe artifact in the dark liquid areas was found in 8 cases with bladder calculus.There was significant difference in morphology of the calculus(P0.05).Conclusions The unique ultrasonic characteristics in infants with melamine calculus had become a very useful tool to diagnose the pediatric urinary melamine calculus.J Appl Clin Pediatr,2009,24(1):67-69

OBJECTIVETo investigate extracellular splitting pattern of mitochondria and the depressant effects of CsA on the process and explore the mechanism of post-traumatic SIRS and its therapeutic strategy.

METHODSTen male SD rats with 60 to 70 days age and 240 to 280 g weight were used for mitochondrial isolation. Freshly isolated mitochondria were randomly divided into two groups, which were cultured in blood plasma with or without CsA respectively for 8 h. COX and MDH were assayed by ELISA every 30 min. Meanwhile, Rat macrophage cell line NR8383 were treated as follows, control (group A): cultivation with normal medium; NR8383+CsA co-culture group (group B): culture medium was supplemented with CsA of 10 mmol/L; NR8383+intact mitochondria co-culture group (group C): culture medium was supplemented with intact mitochondria (mtDNA=5 g/ml); NR8383+intact mitochondria+CsA co-culture group (group D): culture medium was supplemented with intact mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L; NR8383+disrupted mitochondria co-culture group (group E): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml); NR8383+disrupted mitochondria+CsA co-culture group (group F): culture medium was supplemented with disrupted mitochondria (mtDNA=5 μg/ml)and CsA of 10 mmol/L. TNF-α and IL-6 concentrations in supernatant were assessed at 1, 3, 5 h after culture.

RESULTSIn the mitochondria plasma cultures, MDH and COX levels were increased with the time and peaked at about 3 h and 3.5 h; CsA can delay the appearance of peak to 4.5 h. Among different treated groups,there was no significant difference in TNF-α and IL-6 between group A and group B; there was significant difference in TNF-α and IL-6 other groups. After 1 h culture, compared with group C, no significant difference of TNF-α and IL-6 was observed in group D, while TNF-α and IL-6 were significant higher in group E; after 3 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while TNF-α and IL-6 were significantly higher in group E; after 5 h culture, compared with group C, TNF-α and IL-6 were significantly lower in group D, while no significant difference of TNF-α and IL-6 were observed in group E. At each time point, there was no significant difference in TNF-α and IL-6 between group F and group E.

CONCLUSIONMitochondria can split in serum with time, which will further activate macrophages. CsA has depressant effect to mitochondrial splitting on the process and will therefore inhibit the activation of macrophages.

BACKGROUND: Edaravone can alleviate brain injury and improve neurological functions and symptoms. This study aimed to investigate the effect of edaravone on the p38Mitogen-activated protein kinases/Caspase-3 (p38MAPK /Caspase-3) pathway after diffuse brain injury (DBI) in rats. METHODS: DBI models were established according to the description of Marmarou's method. A total of 250 rats were divided (random number) into four groups: control group (CG, n=45), model group (MG, n=77), low-dose edaravone group (n=67, dosage 5 mg/kg) and high-dose edaravone group (n=61, dosage 10 mg/kg). After 1, 6, 24, 48, and 72 hours after injury, brain tissues were collected. The changes of neuron morphous in the hippocampal region were observed through Nissl staining. The expression levels of phosphorylated p38MAPK and caspase-3 were detected by immunohistochemistry and Western blotting respectively. Learning and memory function were tested with Morris water maze from the 3rd to 7th day after injury. RESULTS: Some neurons had histopathologic changes of necrosis and apoptosis in the model group compared with the control group. The phosphorylated p38MAPK expressions increased at 1, 6, 4, and 48 hours (P<0.05), but no significant difference was observed at 72 hours (0.54±0.19 vs. 0.40±0.14, P>0.05). Caspase-3 expressions increased at 6, 24, 48, and 72 hours respectively (P<0.05), but there was no significant difference at 1 hour (0.59±0.29 vs. 0.40±0.17, P>0.05). From the 3rd to 6th day during the Morris water maze test, the latency to find the platform was significantly prolonged (P<0.05) and times of rats crossing the platform was decreased on the 7th day (2.28±1.18 vs. 8.20±1.52, P<0.05). The phosphorylated p38MAPK expressions decreased at 6, 24 and 48 hours respectively in the low dose edaravone group compared with the model group (P<0.05), whereas no significant difference was seen at 1 hour (1.66±0.80 vs. 1.85±0.86, P>0.05). Caspase-3 expression decreased at 6, 24, 48, and 72 hours (P<0.05). The latency to find the platform was significantly shortened (P<0.05), and times of rats crossing the platform increased (4.17±1.15 vs. 2.28±1.18, P<0.05). The above mentioned parameters changed more significantly in the high-dose edaravone group than in the low-dose edaravone group. CONCLUSION: Edaravone can alleviate brain tissue damage after DBI, inhibit p38MAP signal activation after early injury, reduce the expression of caspase-3, and promote the recovery of neurological function in the late period.
