This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.

435 patients with type 2 diabetes were divided into 2 groups according to their fatty liver,then the relations between fatty liver and various parameters in two groups were observed and analyzed by statistical methods.Body mass index,HbA_1c and triglyceride were the risk factors for fatty liver.The prevalences of metabolic syndrome,hypertension and coronary heart disease in fatty liver group were significantly higher than those in the control group.

Objective To investigate the effect of hysterectomy and uterine arterial embolization on the function of ovary.Methods The serum concentrations of estrin(E2), progestogen(P),fouicule-stimulating hormone(FSH),luteotropic hormone(LH) and prolaction(PRL) were measured in 18 patients undergone hysterectomy (group Ⅰ),15 patients undergone uterine arterial emboliation(group Ⅱ) and 30normal women (group Ⅲ or control group).These five hormones were compared in each group.Results The serum concentrations of E2 and P in the group Ⅰ were lower than that in group Ⅲ, there was significant difference between them.The serum concentrations of E2 and P in group Ⅱ and group Ⅲ was no significant difference.Conclusion Hysterectomy has significant effects on the function of ovary,while uterine arterial embolization has not.

The low mass cutoff ( LMCO) is the main weakness of ion trap when it performs tandem mass analysis by collision induced dissociation (CID). LMCO means that some daughter ions of m/ z are less than about 1 / 3 of the m/ z of parent ion could not be detected during the tandem mass spectrometry processing. A new method which can significantly improve the effect of low mass cutoff was proposed and investigated. By simply changing the scan method of digital potential frequency, some low mass ions can be effectively observed during the tandem mass spectrometric experiment. In the experiment, the frequency of the digital ion trapping power and ion activation power were scanned from lower value to higher value, and some lower mass product ions could be detected during CID process. For example, some lower mass ions were observed during the CID of reserpine precursor ion when the frequency of its digital trapping power was scanned from 500 kHz to 560 kHz. The tandem mass spectra of Reserpine ion showed that the experimental results both from this work and the triple quadrupole mass spectrometer were exactly the same.

Objective To summarize the nursing key points of one patient of external ankle foot of gout patients with purulent infection which caused by gout stone burst in order to provide reference for the similar case. Methods Using silver dressing for local treatment of gout during wound, on the basis of control the basic diseases, local wound treatment focus was mainly reflected in: infection control, fluid management and wound debridement. Results After 86 days of treatment. The wound had already healed. Conclusions Rational use of silver dressing gout can promote wound healing and relieve the pain of patients.

Objective To understand the diagnostic value of blink reflex (BR) in central neuropathy by observing the variations of blink reflex in diabetic patients. Methods Electrical pulse was used to stimulate the supraorbital nerve at the supraorbital notch. The responses of bilateral orbicular muscles of the eye were recorded, the variations of the latency and amplitude of R 1 and R 2 recorded on the side of stimulation and of R′ 2 recorded on the contralateral side were measured. Results There was significant prolongation in the latency and lowering of the amplitude of R 1, R 2 and R′ 2 in the diabetic patients compared with the control group. The abnormality rate of BR increased gradually with the prolongation of diabetic duration. Conclusion BR examination might provide an objective index for nervous damage in diabetic patients and it is helpful in early diagnosis of diabetic neuropathy.

Aim To evaluate the antianginal efficacy of trimetazidine in combination with other regular anti-ischemic drugs in the treatment of stable angina. Methods Twenty-two male cases with stable,effort-induced angina and positive exercise ECG test were treated with trimetazidine for 12 weeks.Exercise ECG test was examined again in the end of the study. Results There were obviously increased in exercise tolerance,total exercise workload after treatment(P

Objective To study the SLC26A4 mutations in children with non -syndromic hearing loss by ge-netic testing method ,for the purpose of investigating etiology and mutation regularity of hearing loss ,and to provide basic information for the molecular diagnosis of hearing loss .Methods Blood samples and clinical data of 137 spo-radic cases with non -syndromic hearing loss and 126 normal controls were collected .The SLC26A4 gene of the pa-tients and normal controls were amplified by polymerase chain reaction (PCR) ,then subjected to automatic DNA se-quencing .Results Pathologic SLC26A4 mutations were identified in 23 out of 137 patients ,and in 23 out of 119 bi-lateral deafness ,mutate rate were 16 .79% and 19 .33% ,respectively .SLC26A4 mutations were identified in 19 out of 20(95% ) patients with bilateral LVA .A total of 11 mutations were identified in the present study ,including 4 novel mutations (E29K(c .85G>A) ,R79X(c .235C> T) ,C282G(c .844T>G) ,V285I(c .853G>A) )and 7 repor-ted mutations .In the present study ,IVS7-2A>G was the most common mutation ,and was detected in 19 out of 23(82 .61% ) patients with SLC26A4 mutations .Conclusion SLC26A4 mutations ,the common reason for non -syndromic hearing loss ,were closely related with LVA .IVS7-2A>G was the most common mutation in SLC26A4 mutant .

Objective To investigate the effect of preconditioning with different concentrations of sevoflurane on hypoxia-reoxygenation(H/R)-induced apoptosis in rat hippocampal neurons and the role of mitochondrial KATP(mito-KATP)channels.Methods Primary cultured hippocampal neurons isolated from newborn SD rats(＜24h)of both sexes,weighing 5-6 g,were randomly divided into 7 groups with 48 wells and 12 dishes in each one:control group(C group),H/R group,preconditioning with 6%,4%and 2% sevoflurane groups(S1-3 groups),5-hydroxydecanoate(5-HD,mito-KATP channel blocker)100 μmol/L preconditioning group(5-HD group)and preconditioning with 5-HD 100 μmol/L+6% sevoflurane group(5-HD+S group).The neurons were exposed to 4 h hypoxia followed by 24 h reoxygenation. In S1-3 groups, preconditioning was performed with 6% , 4% and 2% sevoflurane respectively before H/R. In 5-HD group, preconditioning was performed with 5-HD (final concentration 100 μmol/L) before H/R. In 5-HD + S group, preconditioning was performed with 5-HD 100 μmol/L and 6% sevoflurane before H/R. The neuronal viability, apoptosis rate and expression of Bcl-2 and Bax were determined after 24 h reoxygenation.Results The neuronal viability was significantly lower,while the apoptosis rate and expression of Bcl-2 and Bax were significantly higher in the other 6 groups than in group C(P＜0.01).The neuronal viability and expression of Bcl-2 were significantly higher,while the apoptosis rate and Bax expression were lower in S1-3 groups than in group H/R. There was no significant difference in the parameters mentioned above between 5-HD and 5-HD + S groups(P＞0.05).The neuronal viability and expression of Bcl-2 were significantly lower, while the apoptosis rate and Bax expression were higher in S2, S3 and 5-HD + S groups than in group S1, and in group S3 than in group S2(P＜0.0l) .Conclusion Sevoflurane preconditioning can inhibit H/R-induced apoptosis in rat hippocampal neurons and reduce the injury to neurons in a concentration-dependent manner, and the underlying mechanism may be related to activation of mito-KATP channels, up-regulation of Bcl-2 expression and down-regulation of Bax expression.
