Objective To assess the value of CMV viral load test in the diagnosis and prognostic judgment of infantile cytomegalovirus infection with whole blood and urine specimens. Methods 50 infants with active CMV infection were selected, which pp65 antigen was positive in serological detection and either CMV-IgM positive or the titer of CMV-IgG ≥40. The viral load in whole blood and urine specimens was detected before and after a course of preemptive ganciclovir treatment and the pp65 antigen was determined after treatment. Results 98% patients were manifested as cytomegalovirus viral load quantitative measurement in whole blood positive before the treatment, while 14% after. The positive ratio of pp65 assay after therapy was 6%. And there was no significant difference between the results of the two kinds of detection methods measurement in urine before and after treatment was 98% and 90%, respectively. The results of urinary viral load quantitative detection did not coincide with clinical characteristics of CMV infection (P＜0.05,Sp＝0.11,PVP＝0.55, (Youden's index)＝0.09). Conclusions Good coincidence could be found between CMV-DNA quantitative measurement in whole blood and pp65 antigenemia assay. And the former could be used as a diagnostic index of CMV positive infection. While single urinary viral load quantitative detection had no significance for the distinction between active and latent CMV infection and dynamic monitoring of CMV treatment.

mRNAs of alpha-adrenoceptor (α-AR) subtypes are found in neurons in dorsal root ganglion (DRG) and change after peripheral nerve injury. In this study, the distribution of α-AR subtype proteins was studied in L5 DRG of normal rats and rats with chronic constriction injury of sciatic nerve (CCI). Using immunofluorescence technique, it was found that α1A-, α1B-, and α2A-AR proteins were expressed in large, medium, and small size neurons in normal DRG, and significantly increased in all size neurons 14 days after CCI. α1D- and α2C-AR was also expressed in all size neurons in normal DRG. However, α1D-AR was significantly increased and α2C-AR was decreased in small size neurons 14 days post CCI. α2B-AR neurons were not detectable in normal and CCI DRG. Co-expression of α1A- and α2A-AR in the same neuron was observed in normal DRG and increased post CCI. Collectively, these results indicated that there is distinct distribution of α-AR subtypes in DRG neurons, and the distribution and levels of expression of α-AR subtypes change differently after CCI. The up-regulation of α-AR subtypes in DRG neurons may play an important role in the process of generating and transmitting neuropathic pain.

A method for simultaneous determination of the shikonin, acetyl shikonin and β, β'-dimethylpropene shikonin in Onosma hookeri and the chromatographic fingerprint was estabished by HPLC-DAD on an Agilent Zorbax SB-column with a gradient elution of acetonitrile and water at 0.8 mL x min(-1), 30 degrees C. The quality assessment was conducted by comparing the content difference of three naphthoquinone constituents, in combination with chromatographic fingerprint analysis and systems cluster analysis among 7 batches of radix O. hookeri. The content of the three naphthoquinone constituents showed wide variations in 7 bathces. The similarity value of the fingerprints of sample 5, 6 and 7 was above 0.99, sample 2 and 3 above 0.97, sample 3 and 4 above 0.90, and other samples larger than 0.8, which was in concert with the content of three naphthoquinone constituents. The 7 samples were roughly divided into 4 categories. The results above indicated that the using of this medicine is complex and rather spotty. The established HPLC fingerprints and the quantitative analysis method can be used efficiently for quality assessment of O. hookeri.

OBJECTIVE: This paper presents a method for treating maxillary neuralgia, the second division of trigeminal nerve. METHOD: One hundred and thirty six cases with 136 trigeminal neuralgia were treated from 2004 to 2011. All patients were treated with endoscopic surgery at the pterygopalatofossa through approach to the maxillary sinus for resecting maxillary nerve and infraorbital nerve. RESULT: One hundred and eighteen patients were relieved after operation and no recurrence of neuralgia was occurred after 2 to 8 years of follow-up. CONCLUSION This method had the advantages of avoiding to operate craniotomy with no complications, which was performed easily with valid efficacy.

Through an overview of the development of long-term care mode that combined medicine and pen-sion and the existing ethical issues, this paper pointed out that the future long-term care mode should strengthen the enthusiasm of public hospitals to participate in, reduce multiple management by government departments, es-tablish perfect laws and regulations and medical insurance system, enhance the responsibility of the practitioners and the general public, meanwhile, actively practice the principle of humanity and respect, fairness and efficiency, honesty and reliability in ethics, to provide new ideas and directions for the development of this model.

Aim To investigate the pharmacokinetic effect of aspirin on caffeic acid in dengzhanxixin injec-tion( DI) . Methods Concentration of caffeic acid in rat plasma was detected by LC-MS/MS after rats were given intravenous administration of DI or DI combined with aspirin by gavage. Pharmacokinetic parameters were calculated by DAS 1. 0 pharmacokinetic software. Results In vivo pharmacokinetic models of caffeic acid were two-compartment open models in both the caffeic acid group and the caffeic acid combined with aspirin group. After compatibility, caffeic acid showed a significant increase in T 12β, with a slight decrease in CL. Conclusions Aspirin can reduce metabolic process of caffeic acid in vivo.

Objective To study the effect of chloral hydrate on click sound evoked auditory brainstem re-sponse (ABR) in healthy adult guinea pig .Methods A total of 20 healthy wild type albino male guinea pigs were se-lected for ABR assessment with click sound stimulation conscious and cholral hydrate anesthesia conditions .The ABR threshold was determined according to the wave that presents highest occurrence rate under different stimulus intensity .The latency ,interpeak latency of each wave at 90 dB peSPL stimulation as well as the amplitude of waveⅡ ,Ⅲ ,Ⅳ under different stimulus intensity were recorded .Results The ABR threshold in chloral hydrate anes-thesia was 25 .50 ± 2 .76 dB peSPL and at the waking state was 28 .5 ± 3 .66 dB peSPL from control group (P>0 .05) .The latencies of each wave recorded under chloral hydrate anesthesia state were prolonged compared to those of under waking state ,wave Ⅲ ,Ⅳ and Ⅴ had significance differences (P<0 .05) ,but wave Ⅰ ,Ⅱ had no significant differences (P>0 .05) .The interpeak latency between wave Ⅰ - Ⅴ ,Ⅲ - Ⅳ ,Ⅳ - Ⅴ in chloral hydrate anesthesia were longer compared to those of under waking state with significant differences (P<0 .05) ,while interpeak latency between Ⅰ - Ⅱ ,Ⅱ - Ⅲ had no significant differences (P> 0 .05) .The amplitude and occurrence rate of wave Ⅱwere the highest among all the waves in both experimental group and control group .The amplitude of wave Ⅱ and Ⅲ in chloral hydrate anesthesia was higher than that of the waking state under acoustic stimulation conditions ofhigh intensity(P<0 .05) while the amplitude of wave Ⅳ was lower than the waking state (P<0 .05) .Conclusion The chloral hydrate anesthesia may be able to apparently lengthen the ABR latencies of wave Ⅲ ,Ⅳ ,Ⅴ and affect the amplitude .This effect should be considered during the assessment of ABR under anesthesia state in guinea pig ;The ABR threshold of guinea pig could be determined according to the wave Ⅱ because it 's highest occurrence rate .
