OBJECTIVETo study the effect of long-term use of low dose Caulis Aristolochiae Manshuriensis (CAM) on the deterioration of chronic renal failure rats.
METHODSThe 5/6 nephrectomized Wistar rats were taken as animal model of chronic renal failure, which were divided into 3 groups. Group A was treated with 1 g/kg CAM decoction, the dose equivalent to that defined in the pharmacopoeia. Group B was treated with 3 g/kg CAM decoction and Group C treated with equal volume of tap water. Medication was given once per day by gastrogavage in all the three groups for 8 weeks. The serum creatinine, urea nitrogen, urinary protein content and morphological changes of kidney were observed.
RESULTSAfter 8 weeks treatment, levels of serum creatinine, urea nitrogen, urinary protein excretion in Group B were higher than those in Group C significantly, they were 165.0 +/- 15.6 mumol/L vs 109.8 +/- 10.0 mumol/L, 27.8 +/- 3.6 mmol/L vs 18.7 +/- 2.5 mmol/L and 68.2 +/- 10.1 mg/24 hrs vs 44.6 +/- 8.5 mg/24 hrs, respectively, all P < 0.05. The pathological changes of renal mesenchyme and degree of glomerulosclerosis were also heavier in Group B.
CONCLUSIONThe susceptibility of chronic renal failure rats to the nephrotoxicity of CAM increases in long-term use of low dose CAM which could accelerate the deterioration of renal impairment in the model rats.

OBJECTIVETo determine the incidence of work-related acute pesticide poisoning among farmers in Jiangsu Province and to identify the risk factors.
METHODSMulti-stage stratified sampling and cluster sampling methods were used to randomly select 1490 farmers from the south (Z village), centre (Y village) and north (X village) of Jiangsu Province. The database was established by EpiData 3.1. SPSS 17.0 and SAS 9.13 were used to do chi-square test, trend chi-square test, single factor and multi-factor logistic regression analysis.
RESULTSAmong 1490 farmers, 121 people had work-related acute pesticide poisoning in the past year. The incidence rate in Jiangsu Province was 8.1%. 118 farmers (97.5%) were mild pesticide poisoning.3 farmers (2.5%) were moderate pesticide poisoning. The incidence rate of Work-related acute pesticide poisoning in X village of North Jiangsu Province (13.5%, 68/505) is obviously higher than that in Y village of Central Jiangsu Province (4.8%, 19/399) and Z village of South Jiangsu Province (5.8%, 34/586), and the difference is statistically significant (χ(2) = 29.60, P < 0.01). The incidence rate of Work-related acute pesticide poisoning in female (10.4%, 58/557) is obviously higher than that in male (6.8%, 63/933), and the difference is statistically significant (χ(2) = 6.26, P < 0.05). There are lack of safety guidance, unsafety application methods (without alternate row spraying, without backward application, without down-wind application) and risk behaviors in the spraying (without read labels, preparing pesticides without gloves, wiping sweat with hand (s), equipment leakage, body pollution by pesticide, working when feeling sick, without bath after work). If farmers have risk behaviors above, the incidence rate of Work-related acute pesticide poisoning will be obviously higher than farmers who receive safety guidance and have no such dangerous behaviors, and all the differences are statistically significant (P < 0.05). The group of 24 ∼ 34 years old has the highest risk of work-related acute pesticide poisoning (OR = 7.15).
CONCLUSIONThe incidence rate of work-related acute pesticide poisoning among farmers in Jiangsu Province was higher. Effective measures are needed to prevent and reduce the occurrence of work-related acute pesticide poisoning. We can teach the farmers who spray pesticides about safety guidance, safety application methods and avoiding risky behaviors.

OBJECTIVETo evaluate the clinical outcomes of primary anterior radical debridement, bone autograft, and sacral rod fixation for the treatment of tuberculosis of the lumbosacral segment.
METHODSFrom March 2004 to November 2008,11 patients with tuberculosis of the lumbosacral segments received antituberculosis medications for 2 to 3 weeks before anterior radical debridement, autologous iliac bone grafting, and internal sacral rod fixation. Among the patients, 5 patients were male and 6 patients were female, with an average age of (44.45 +/- 8.50) years (ranged from 29 to 56 years). The average time from stage of onset to operation was 11 months (ranged from 8 to 15 months). All the patients presented with various degrees of lower back pain; one patient experienced preoperative lower extremity radicular pain, while 2 patients experienced saddle area anaesthesia. However, only 6 patients exhibited mild to moderate tuberculous toxic reactions. All the patients were evaluated by plain radiography, computed tomography (CT), and magnetic resonance imaging (MRI). The diagnosis of tuberculosis was made with reference to clinical and radiological findings. Surgery was performed when the toxic symptoms of tuberculosis were controlled and erythrocyte sedimentation rates (ESR) decreased to (37.2 +/- 9.6) mm/h (25 to 54 mm/h). Lumbosacral angle, visual analogue scale (VAS) scores, ESR, and neurological performance were assessed before and after surgery.
RESULTSAll surgical procedures were performed successfully without intra or postoperative complications. There were no instances of spinal tuberculosis recurrence. Patients were followed up for a mean of (19.64 +/- 5.43) months. The mean lumbosacral angle significantly increased from the preoperative mean (12.9 +/- 5.0) degrees to postoperative (21.5 +/- 6.1) degrees and at final follow-up (20.1 +/- 5.2) degrees (P < 0.001). The mean VAS scores and ESR significantly decreased from preoperative (7.3 +/- 1.2) score and (37.2 +/- 9.6) mm/h respectively to final follow-up (0.6 +/- 0.5) score and (10.5 +/- 2.3) mm/h respectively (P < 0.001). Bone fusion occurred in all patients at a mean of (9.0 +/- 1.9) months (ranged 6 to 12 months) after surgery. Three patients who had impaired neurological performance before surgery had normal neurological performance after surgery.
CONCLUSIONOur findings suggest that anterior radical debridement, interbody fusion, and sacral rod fixation can be an effective treatment option for lumbosacral segment tuberculosis.
