OBJECTIVETo explore the effects of sacral canal injection on nerve root local inflammatory factors in rat model with lumbar disc herniation, in order to identify its mechanism of treatment.

METHODSForty-eight male SD rats were randomly divided into sham operation group(group A), model group (group B), Chinese medicine group(group C) and western medicine group(group D). There were 12 rats in each group. The model of lumbar disc herniation was established using compression and inflammatory stimulation in group B, C, D. All rats were given epidural catheterization and group A and B with physiological saline (1 ml/kg), group C with mixed liquor of 2% lidocaine and compound Danshen injections and physiological saline (2:2: 16) and group D with mixed liquor of 2% lidocaine and triamcinolone acetonide injection and physiological saline (2:2:16), once a week for a total of three treatments. Four rats were killed every 1 week after injection for once, and the inflammatory factors of tumor necrosis factor (TNF-alpha), prostaglandin E2 (PGE2), interleukin-l (IL-1) and interleukin-6 (IL-6) were detected by ELISA method.

RESULTSThe levels of TNF-alpha, PGE2, IL-1 and IL-6 in compressed nerve tissues in group B were increased than those of group A (P < 0.01). The levels of PGE2, IL-1 and IL-6 in group C and D were decreased than those of group B, and group D was much less(P<0.05). There was no significant difference in level of TNF-alpha among group B, C, D (P > 0.05).

CONCLUSIONCompound compression with inflammatory stimulation can lead to massive release of inflammatory mediators, such as TNF-alpha, PGE2, IL-1 and IL-6. Both injection with compound Danshen injections and triamcinolone acetonide injections by sacral canal can reduce the levels of part inflammatory mediators (PGE2, IL-1 and IL-6), and the effect of Glucocorticoid is better than Danshen (P < 0.05).

Objective To analyse the clinicopathological features of primary small intestine lymphoma(PSIL), and explore the relationship between clinical stage,histological findings,therapeutic modality and prognosis. Methods The clinical data of 34 cases of PSIL were collected,the pathohistological features and results of immunohistochemical examinations were obtained,and the follow-up findings were adopted for comprehensive analysis. Results Among these 34 cases of PSIL,abdominal pain or discomfort,gastrointestinal bleeding and abdominal mass were the predominant symptoms.PSIL mainly involved ileum,especially the bottom of ileum and ileocecal area.Among the 26 patients with follow-up for more than one year,the 1-year survival rate was significantly higher in patients without tumor perforation than those with tumor perforation(76.2% vs 20.0%)(P

OBJECTIVETo study the efficacy and safety of Reinhartdt and sea cucumber capsule (RSC) combined with donepezil in treating Alzheimer's disease (AD), and its effect on thyroid function axis.

METHODSSixty-eight patients were randomly assigned to the RSC group, the Donepezil group and the combined treatment group, who were treated for 3 and 6 months with RSC, Donepezil and RSC combined with Donepezil, respectively. The curative effect was evaluated by scoring according to Mini-Mental State Examination (MMSE), ADAS-Cog and ADL chart, and the level of thyroid hormones, including TSH, FT3, FT4, TT3 and TT4, were measured with radioimmunoassay before treatment, 3 and 6 months after treatment respectively.

RESULTSAs compared with the baseline, MMSE score increased, ADAS-Cog score and ADL score decreased significantly in all the three groups after 3 months and 6 months of treatment (P < 0.05 and P < 0.01), but the improvement in the combined treatment group was more significant than that in the other two groups (P < 0.01). After 6 months of treatment, the levels of FT3 and FT4 in the combined treatment group were significantly changed (P < 0.01), but no significant change in all the thyroid hormones was found in the other two groups. No obvious adverse reaction occurred in all the three groups.

CONCLUSIONRSC combined with Donepezil in treating AD is effective and safe with no evident adverse reaction, better than single drug treatment, which may be through influencing the metabolism of thyroid hormones to improve the cognition function of AD patients.

OBJECTIVETo explore the feasibility of inducing human umbilical cord mesenchymal stem cells (HuMSCs) to differentiate into Leydig cells through conditioned medium derived from Leydig cells.

METHODSHuMSCs and Leydig cells were obtained by tissue blocks culture attachment and enzymatic digestion respectively. HuMSCs were induced by conditioned medium of Leydig cells as an experiment group while those before induction were cultured as a control group. The expressions of LHR, 3β-HSD and StAR in the induced HuMSCs were determined by RT-PCR after 3, 7 and 10 days of culture; those of CYP11A1, CYP17A1 and 3β-HSD measured by immunofluorescence staining after 2 weeks; and that of 3β-HSD detected by Western blot after 4 weeks.

RESULTSThe experimental group showed positively expressed LHR, 3β-HSD and StAR at 3, 7 and 10 days, CYP11A1, CYP17A1 and 3β-HSD at 2 weeks, and 3β-HSD at 4 weeks, while the control group revealed negative expressions at all the time points.

CONCLUSIONInduced with conditioned culture medium derived from Leydig cells, HuMSCs are likely to differentiate into steroidogenic cells and eventually into Leydig cells.

Objective To study the effect of intensive trunk muscle training on balance and walking in pa- tients with hemiplegia caused by stroke.Methods A total of 90 stroke patients were recruited and randomly divid- ed into a treatment group(45 cases)and a control group(45 cases).All the patients were given conventional reha- bilitation training.Meanwhile,intensive trunk muscle training was also administered for those in the treatment group as well.The trunk control function,balance ability and walking ability were assessed by using the trunk control test, Berg Balance Scale and the balance subscale of the Fugl-Meyer physical performance test,and Holden's functional ambulation classification,respectively,before and after 6 weeks of training.Results It was found that all the pa- tients scored better with the trunk control test,Berg's balance scale,the balance subscale of the Fugl-Meyer physical performance test and Holden's ambulation classification after treatment,and there were significant differences between the two groups after treatment(P

Twelve cases of Bartter's syndrome were reported and reviewed retrospectively.Usually vomiting was the first sympton in children,while fatigue was common in adults.Bartter's syndrome was characteristic of hypokalemia,metabolic alkalosis,elevations of plasma renin activity,serum angiotersinⅡand aldosterone and juxtaglomerular apperatus hyperplasia.Supplementation of potassium choloride was the main manner of therapy.

OBJECTIVETo study the efficacy and safety of the combined treatment with compound Reinhartdt and Sea Cumber Capsule (RSC, a Chinese medicinal preparation consisted mainly of Reinhartdt and Sea Cumber) and Donepezil for vascular dementia (VD), and its effect on thyroid function axis.

METHODSSixty-three patients with VD were treated respectively with RSC, Donepezil and the combined treatment. MMSE, ADAS-Cog and ADL scales were used to evaluate the condition of patients before treatment as well as at 3 months and 6 months after treatment. Meanwhile, levels of thyroid hormones, including (TSH, FT3, FT4, TT3, TT4) were measured with radioimmunoassay.

RESULTSAs compared with the baseline, MMSE score increased, ADAS-Cog score and ADL score decreased significantly in all the three groups after 3 months and 6 months of treatment (P <0.05, P<0.01), the improvement in the Donepezil group was more significant than that in the RSC group after 6 months of treatment (P < 0.05), but the combined treatment group showed the best efficacy (P < 0.01). After 3 months of treament, the levels of FT3 and FT4 in the combined treatment group increased, but showed no statistical significance (P >0.05). However, significant changes were found at 6 months after combined treatment (P < 0.01). No significant changes were seen at all in levels of TSH, TT3 and TT4 (P > 0.05). FT3, FT4 increased without statistical significance after 6 months Donepezil treatment, TSH, TT3 and TT4 also showed no significant difference in the Donepezil group and no other significant changes of thyroid hormones was seen in patients treated with RSC (P > 0.05). No obvious adverse reaction occurred in any of the three groups.

CONCLUSIONCombined treatment of RSC and Donepezil was effective and safe on VD patient, with the efficacy much better than either of them alone. No significant adverse reaction was observed. The regulation on thyroid hormones may one of the mechanisms of the combined treatment in improving cognitive function.
