The article describes the development of new magnetic bead separation and purification instrument. The main application of the instrument is to capture tubercle bacillus from sputum. It is a pretreatment instrument and provides a new platform to help doctors to diagnose bacillary phthisis. Not only could it be used for tubercle bacillus capturing, but also for gene, protein and cell separating and purification. Because the controller of the instrument is 16-bit single chip microcomputer, the cost could be greatly reduced and it will be widely used in China.

Objective To compare Pulmicort and Dexamethasone’s curative effects for acute laryngitis in children. Method Children with acute laryngitis were divided into PUL group and DEX group according their therapy methods. The curative effects and recurrence time were compared. Results The efficiency rate in PUL group was significantly higher than in DEX group (P<0.05). The therapy 3 d and post-therapy dyspnea, hoarseness, bark-like cough and stridor score in PUL group were significantly lower than in DEX group (P<0.05), and the recurrence time of dyspnea, hoarseness, bark-like cough and stridor was significantly shorter (P<0.05). Conclusion Pulmicort could significantly improve the symptoms and signs for children with acute laryngitis with few side effects. Its curative effects are better than dexamethasone.

Objective To study the hygroscopicity of glucosamine sulfate powder.Methods Hygroscopic studies were conducted on glucosamine sulfate powder at 5℃ and 30℃ used gravimetric method,determined the equilibrium moisture content(EMC) and drew the moisture sorption isotherms.The experimental values were regressed using the BET model,calculated the monolayer moisture content.Results At 30℃,when water activity exceeded 0.43,samples agglomerated,browned and lose adsorbed water,EMC declined;At 5℃,the isotherm had typical ob-S shape,the EMC increased with water activity raising.At 30℃ and 5℃,the monolayer moisture content were 4.8633,5.5740g/100g respectively.Conclusion At 5,30℃ the appropriate aw for storage appeared to be below 0.3056,0.2784,respectively.

The kiwifruit germplasms in Jiangxi province were identified by amplified fragment length polymorphism(AFLP)markers．Four primer pairs that had been selected from 64 ones had detected a total of 190 bands among 31 germplasms of kiwifruit,one hundred and seventy nine bands that representing 94．2％of total bands were polymorphic．The identification rates of 31 germplasms were up to 100％．The result suggests that applying AFLP markers to analyze the kiwifruit germplasms is feasible．Then Clustering analysis the AFLP resuit by UPGMA．The dendrogram indicated that the Dice similarity coefficients of 31 germplasms of kiwifruit ranged from 0．50 to 0．85,it suggested that their genetic relationships weren't near．Thirty one germplasms could divide into four groups according to the Dice similarity coefficient 0．56．Sect．Leiocarpae and Sect．Maculatae clustered into one group；A．Melliana of Sect．Strigosae was one group；A．Chinensis var. Rufopulpa,A．Eriantha,A．Fulvicoma var．Lenata,A．Styracifolia and A．Jiangxiensis in Sect．Stellatae clustered into the same group；but the two germplasms of Sect．Stellatae,A．Deliciosa and A．Chinensis clustered into the other group．Interestingly,the‘Ganmi-5’was in the same rank with A．Chinensis from the dendrogram,but it was the variety of A．Chinensis according to the traditional classification．It is necessary that the‘Ganmi-5’should be further researched in classification．The genetic relationships among the kiwifruit germplasms in Jiangxi province were identified and characterized by themolecular method,which was consistent with the traditional classification in certain degree and provided new evidences for the classification of the kiwifruit germplasms．

Objective To evaluate the incidence of benign gallbladder disease and the relationship between the hyperlipidemia and gallbladder stone in Hefei district by a survey in 6?946 persons. Methods All benign gallbladder diseases were discovered by Colour Dopple ulterasound. The data of lipidemia were analyzed and a comparative study of 1?051 cases suffering from gallbladder stone with the control group was done. Results The morbidity of benign gallbladder diseases was 21 55%. The prevalence of gallbladder stone, gallbladder polypoid lesion, cholecystitis, intrahepatic cholelithiasis or choledocholithiasis were 15 13%, 3 39%, 1 35%, 0 96%, 0 70% respectively in all examined. The morbidity of gallbladder stone was 70 2% in the benign gallbladder diseases. The incidence of hyperlipidemia both in gallbladder stone group and control group were 56 9% and 32 3% ( P

To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective To lay foundation for the establishment of national standards of electroacupuncture devices by exploring the problems existing in their clinical application.Methods An analysis was made of the models, stimulus waveforms and complex waveform characteristics, stimulus frequencies, current intensities and pulse widths of electroacupuncture devices reported in clinical literature. The actual output frequencies of three kinds of electroacupuncture devices were measured using RM6240C multi-channel physiological signal acquisition and processing system to observe the accuracy of their actual output parameters and summarize the problems existing in electroacupuncture devices. Results The reports on electroacupuncture device parameters showed that of the five indicators analyzed statistically, the frequency of described waveforms was the highest (96.2%); the frequencies of described models (88.8%), stimulus frequencies (61.7) and current intensities (11.2%) were next; the frequency of described pulse widths was the lowest (1.8%). The electroacupuncture device most commonly used clinically was G6805 series, but the subtypes were confused because of many manufacturers. The waveform was described more frequently but complex waveform characteristics were less. The difference of frequencies of clinical application of electroacupuncture was larger. They were from 0.8-400 Hz but described less accurately. The output frequency was indicated by the range in most of the literature. The output adjusters of the three kinds of electroacupuncture devices did not correspond to their actual output frequencies. There was a larger difference between the actual range of output frequencies and the adjustable frequency range indicated in the instruction.Conclusions Electroacupuncture devices have the problems of lacking a display unit of actual output parameter values, the adjusting parameters of the knob adjustable controller being not precise enough and the actual values of output frequencies not reaching the rated range in the instruction.

Atomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit presynaptic noradrenaline transport protein,strengthen noradrenaline's resupination effect,and increases noradrenaline's activity released by synaptic cleft to improve the symptoms of the attention deficit hyperactivity disorder(ADHD)patients.ADHD patients often accompany with other psychological diseases like oppositional defiant disorder,anxiety disorder,which may hinder the diagnosis of ADHD.There is still no accepted effective medicine nowadays.Currently,research on the treatment of the ADHD is more and more popular.Good therapeutic effect of atomoxetine to treat ADHD has been found in resent studies.This article summarized the current management of using atomoxetine to treat ADHD.
