Toll-like-receptors(TLRs) have been found to play a critical role in immune response of hosts.They can trigger innate immune responses by detecting pathogen-associated molecular patterns(PAMPs).This paper reviews the roles of several toll-like receptors(TLR4,TLR5,and TLR9) in radioprotection and the related mechanisms,so as to provide theoretical evidences for further studying their roles in radioprotection.

OBJECTIVE: To explore the applicability of Capacity of Sexual Self-defense Assessment Scale (CSSAS) in psychiatric patients without mental retardation. METHODS: Eighty-seven cases required for assessment of the capacity of sexual self-defense were collected and evaluated by trained professionals according to CSSAS, and the results were compared to the experts' opinions. RESULTS: The scores of three grades of capacity of sexual self-defense (none, limited and whole) were 5.97 +/- 5.83, 32.22 +/- 10.15 and 61.60 +/- 13.02, respectively, which were statistically significant among them (P < 0.01). The correlation coefficients between items and total score were 0.59 to 0.91, the Cronbach's alpha value was 0.96, the spilt half Cronbach's alpha value were 0.94 and 0.91, respectively, and the relation coefficient between them was 0.94. According to the original cut off scores, the Kappa value between scale results and experts' opinions was 0.32 (P < 0.01). By redefining the cut off scores, the Kappa value was improved to 0.84 (P < 0.01). Two factors were extracted by means of the factor analysis. The explanation rates of variance were 46.15% and 28.93%, respectively. The accuracy of retrospective cumulative square was 94.30%. CONCLUSION The CSSAS could be applied in the psychiatric expertise of the capacity of sexual self-defense in psychiatric patients without mental retardation; however, the cut off scores and the factor weight should be redefined.

ObjectiveTo investigate advantage and disadvantage of different rehabilitation therapies used for cerebral palsy (CP) children complicated with epilepsy (EP).Methods140 CP children complicated with EP screened from 1402 CP cases, were analyzed for CP and EP types, MRI or CT, brain stem auditory evoked potentials (BAEP). All cases were treated with anti-epilepsy drugs (AEDs). Different rehabilitation therapies, including electrotherapeutic modalities, acupuncture, point injection, cerebroprotein hydrolysate injection, manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection were assessed.ResultsIn all 140 cases, a majority of EP types were myoclonic seizure and west syndrome, CP type was spasticity. Abnormality showed in MRI or CT (98%) and BAEP (90%). AEDs were effective for all 140 cases. Electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection could make EP severely, but manual therapy, functional training, Chinese herb braising therapy, cattle encephalon glycoside and ignotin injection had no adverse effects on EP cases.ConclusionThe principles of rehabilitation treatment for the CP children complicated with EP are taking AEDs early and in a long term, avoiding electrotherapeutic modalities, acupuncture, point injection, and cerebroprotein hydrolysate injection, using manual therapy, functional training, Chinese herb braising therapy, and cattle encephalon glycoside and ignotin injection.

Hypothyroidism is a common endocrine disease.Its treatment depends on thyroid hormone replacement therapy.Currently,levothyroxine (L-T4) is the preparation recommended by many guidelines.However,there are some L-T4-treated patients with normal TSH levels and persistent non-specific symptoms and discomforts.Therefore,combination therapy with L-T4and liothyronine (L-T3) has been considered as an alternative option for hypothyroidism.However,more prospective studies are needed to provide evidence-based effects for this kind of regimen.

Objective To study the effects and techniques of microsurgical resection of giant hypervascular meningiomas. Methods A retrospective analysis was performed on clinical data of 32 cases of giant hypervascular meningiomas in this hospital from June 1999 to June 2002. Results The Simpson Grade 1 resection was achieved in 15 cases, Grade 2 in 9 cases, Grade 3 in 6 cases, and Grade 4, 2 cases. There were 2 fatal cases. Complications included 4 cases of intracranial hematoma, 6 cases of cerebral edema and infarction (re-operation of decompression was required in 4 cases), 1 case of mutism, 3 cases of cerebrospinal fluid leakage, and 1 case of intracranial infection. The mental dysfunctions or symptoms became worse than before the operation in 7 cases. Follow-up checkups in 30 patients found no recurrence in Simpson Grade 1 resection, 4 cases of recurrence in Simpson Grade 2 resection, and 5 cases of recurrence in Grade 3 and 4. A re-operation was performed to remove the tumor in 6 cases. The size of tumor was unchanged during follow-up period in 7 cases undergoing radiotherapy. Postoperatively, assessments with activity of daily living (ADL) associated with mental dysfunctions revealed grade Ⅰ in 25 cases, grade Ⅱ in 5 cases, and grade Ⅲ in 2. No significant differences were seen in ADL assessments before and after operation (P=0.696). Conclusions Every effort should be made to complete the total resection of intracranial meningiomas. Sufficient preoperative preparation, adequate surgical exposure, efficient management of operative bleeding, and fractionated resection of tumor using microsurgical techniques are important factors to improve clinical outcomes.

Objective To develop a method for separation and determination of safrole and 6-methyl coumarin in cosmetics by GC-MS. Methods The cosmetics were extracted with methanol and then dehydrated,and filtrated through the membrane of 0.45 ?m. The filtration liquid was injected into GC and GC-MS for detection and quantitative analysis with external standard method. Results The recovery rates of safrole and 6-methyl coumarin were 101.3%-106.0% and relative standard deviations of safrole and 6-methyl coumarin were 0.9%-1.4% and 0.9%-2.1% respectively. The detection limits were 5 and 10 ?g/g. Conclusion This method is accurate and sensitive for detection of safrole and 6-methyl coumarin in cosmetic.

Objective To evaluate the therapeutic efficacy of the circumferential procedure for prolapsed hemorrhoids (PPH) in the treatment of third or fourth degree hemorrhoids Methods A total of 32 patients with Ⅲ or Ⅳ degree of circular prolapsed hemorrhoids received operation of PPH The mean age of the patients was 42 5 years old with hemorrhoids history of 5 42 years Results The mean operating time was 9 2 minutes and hospital stay was 3 3 days after operation Eighteen patients complained of local anal pain and 6 patients suffered from temporary urine retention after operation Postoperative bleeding was found in 7 cases on days 3 and 6 after operation, but it was cured by conservative methods No complications were found during the follow up of 2～10 months Conclusion PPH is a safe and effective treatment for hemorrhoids at the third and fourth degree with the advantages of shorter time of inpatient stay and earlier return to normal activity and quicker recovery However, the long term outcome remains to be identified

Objective:To establish a sensitive and fast HPLC method for determining cucurbitacin IIa in rat plasma and investigate the pharmacokinetic characteristics after intravenous administration. Methods: The analysis was performed on a Dikma Diamonsil C18 column (250 mm × 4. 6 mm, 5 μm) at 35℃ with the mobile phase of acetonitrile-water (45∶ 55, v/v) and the UV detection at 212 nm. The plasma samples were collected after intravenous administration at different time points and measured by HPLC. The pharmaco-kinetic parameters were calculated by DAS 2. 0 software. Results: The calibration plot of cucurbitacin IIa was linear over the range 0. 146-14. 060 μg · ml-1 . The range of method recovery was 99. 02%-104. 22% and that of extraction recovery was 84. 74%-86. 80%. The intra-and inter-day precision were both less than 5%. The stability met the requirements. The main pharmacokinetic pa-rameters were showed as follows:t1/2β(h):0.732 ±0.151, 0.681 ±0.055,0.667 ±0.064;Vd (L·kg-1):0.147 ±0.089, 0.131 ±0.095,0.153±0.047; Cl(L·h-1·kg-1): 0.287±0.031,0.304±0.063,0.318±0.029andAUC0→∞(mg·h·L-1):3. 646 ± 1. 124,4. 916 ± 1. 227,9. 385 ± 1. 419. Conclusion: The validated method is successfully applied in basic pharmacokinetic study in rat plasma after intravenous administration. The plasma concentration-time curves at three dosages are all fitted three-compart-ment model. Within the examined dose range, the pharmacokinetics of cucurbitacin IIa in rat is based on linear pharmacokinetics.
