OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

In order to obtain active recombinant PNGase F in Escherichia coli, a prokaryotic expression vector pET28a/PNGase F was constructed. Amplification of PNGase F was obtained using PCR technique employing suitable primers designed according to the PNGase F gene sequence from Flavobacterium nmeningosepticum. The expression of PNGase F gene in LB medium or M9 medium led to the formation of inclusion body and soluble protein, respectively. The refolding of the denatured inclusion body was successful by gradual dilution. Further purification of the refolded protein and soluble crude extract from M9 medium with Ni2+ -NTA argarose resulted a 90% purified PNGase F. The purified protein catalyzed the complete and intact cleavage of N-linked oligosaccharides from various glycoproteins. The efficiency of this cleavage was affected by the substrate status in the reaction system. In summary, we have developed an enzyme production system where PNGase F was over-expressed in recombinant E. coli. This system can provide more than 15 mg/L purified active PNGase F. This purified active PNGase F can be used as tools in analyzing the oligosaccharide structure.

OBJECTIVETo observe the clinical efficacy and safety on moderate and severe persistent allergic rhinitis treated with acupuncture.

METHODSSixty-six patients of moderate and severe persistent allergic rhinitis were randomized into an acupuncture group (34 cases) and a western medication group (32 cases). In the acupuncture, group, acupuncture was applied to Dazhui (GV 14), Feishu (BL 13), Pishu (BL 20), Ganshu (BL 18) and Shenshu (BL 23) in the prone, retained for 20 min; then in the supine, at Baihui (GV 20), Yintang (GV 29), yingxiang (LI20) Taichong (LR 3) and Hegu (LI 4), retained for 20 min. Acupuncture was given once every two days, three times a week, continuously for 8 weeks. In the western medication group, cetirizine hydrochloride was taken orally, 10 mg each time, once every day, continuously for 8 weeks. Separately, before treatment, after the treatment of 1 and 2 months and in 1 month after treatment, the total nasal symptom score (TNSS), the scores in the emotion rating scale for Ganzangxiang of TCM (ERSG) and the rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTS(1) For TNSS, the results after 1 and 2 months treatment and in 1 month after treatment were all, reduced as compare with that before treatment separately in the two groups (P < 0.05, P < 0.01) The result after 2 months treatment was lower than that after 1 month treatment in the acupuncture group (P < 0.05). In 1 month after treatment, the result in the acupuncture group was lower than that in the western medication group (P < 0.05). (2) For ERSG, the score after 2 months treatment was lower than that before treatment in the two groups (both P < 0.05). The score after 2 months treatment in the acupuncture group was lower than that in the western medication group (P < 0.05). (3) For RQLQ, the score after 1 month treatment was lower than that before treatment and the score after 2 months treatment was lower than that after 1 month treatment in the two groups (all P < 0.05). The score after 1 and 2 months treatment and in 1 month after treatment in the acupuncture group was lower than that in the western medication group separately (all P < 0.05). (4) The total effective rate was 91.2% (31/34) in the acupuncture group and was 90.6% (29/32) in the western medication group, without significant difference between the two groups (P > 0.05).

CONCLUSIONAcupuncture is the safe and effective intervention on moderate and severe persistent allergic rhinitis. Compared with the western medicine group, the efficacy in the acupuncture group presents much more advantageous at its durability.

Taking the First Hospital Affiliated to Traditional Chinese Medicine University of Guangzhou as an example,the paper puts forward to establish the hospital's intelligent Short Message Service (SMS) follow-up visit system based on the analysis of research conditions and existing problems of domestic and overseas follow-up visit system,introduces the follow-up visit registration process and functional modules,and summarizes the application efficiency.This system can greatly improve the follow-up visit efficiency,reduce the rate of loss to follow-up visit,and immediately update information of patients.

Mycelial morphology are exploited a great influnence to the metabolites of fungi. The effect of the mycelial morphology on producing lycopene by Blakeslea tripora was investigated. The results indicated that pellets has little role on fermentation when adding kerosene and triton-x100, However, The content of lycopene in the medium reached to 98.6mg/L by adding Ig/L span-20, forming dispersed mycelia, which is 3 times of the control experiments.

As an important part of Chinese medicinal materials, uncommon-territorial herbs are also the most complex parts in the herbal medicine markets. Through years of investigation on the key markets of Chinese herbal medicine, the meaning of uncommon-territorial herbs, their historical evolution, origin and characteristics were clarified in this paper, and some countermeasures were put forward for its development.

The tracheocutaneous fistula after tracheostomy is a complex clinical problem. An ideal fistula closure is still difficult at present though a variety of fistula-closing methods have been reported in the literature. We used a turnover skin flap to cover the fistula. All the procedures were completed at bedside under local anesthesia. The fistula was successfully closed and well healed without complications within 7-9 days. It has been proven that this operation is simple, effective, and safe.
