Glycosylation, one of the most common and important reactions in biological systems, results in diverse functions and is often found in biologically active small-molecule natural products produced by microorganisms. Furthermore, sugar moieties are generally critical for their activities. Alternating the sugar structures thus provides the potentials for enhancing the biological activities of natural products, which evokes researchers to study the sugar biosynthetic machinery and its application in the modification of sugar moieties with an aim of generating unnaturally glycosylated natural product drugs with better activities. This review will briefly outline current studies on sugar biosynthesis and glycosyltransferase, with a few selected experiments designed to alter natural-product sugar structures.

Objective To observe the therapeutic effect of traditional Chinese medicine(TCM)granules made by the formula of Shegan Mahuang decoction for treatment of patients with asthma. Methods A prospective study was conducted,51 cases of light to moderate asthma(cold type)patients were randomly divided into treatment group (25 cases)and control group(26 cases). Conventional symptomatic treatments were of the same in two groups. The patients in control group were given salbutamol aerosol inhalation,100μg each time,4 times per day;based on the treatment of the control group,additionally the above mentioned TCM granules dissolved in water was administered orally 1 dose/day taken twice once in the morning and another once in the evening in treatment group. The therapeutic course was 12 weeks in both groups. Before and after treatment,the asthma control test(ACT)score,forced expiratory volume in 1 second(FEV1)and peak expiratory flow(PEF)were observed. The therapeutic effect,adverse reaction and compliance were evaluated. Results The number of patients with asthma completely controlled in the treatment group was significantly higher than that in the control group(16 cases vs. 9 cases,χ2=4.82,P=0.028). In the patients of two groups,FEV1,PEF and ACT scores were significantly improved after treatment,and in the treatment group,they were obviously higher than those in control group〔FEV1(L):2.67±0.46 vs. 2.32±0.47,PEF(L/min):327.6±49.4 vs. 273.1±42.8,ACT score:22.8±2.0 vs. 21.1±2.6,all P<0.05〕. After treatment,FEV1%predicted value was increased in the treatment group but decreased in control group,there was significantly statistical difference〔(0.68±0.07)% vs.(0.80±0.11)%,P<0.05〕,no significant adverse reaction was found,compliance was good. Conclusion TCM granules made by formula of Shegan Mahuang decoction can improve the clinical symptoms, pulmonary function and control level in patients with asthma,so it is an effective medicine for the control of asthma.

Objectives To investigate the relationship between atherosclerotic acute myocardial infarction (AMI),acute cerebral infarction (ACI)and homocysteine (Hcy). Methods Three hundred and twenty consecutive patients with primary acute myocardial infarction (AMI)(group A)were admitted to the Department of Cardiology,310 patients with primary large artery atherosclerotic cerebral infarction (group B)were admitted to the Department of Neurology,and 327 healthy individuals without cardiovascular and cerebrovascular diseases (group C)at the Department of Physical Examination,Xuanwu Hospital, Capital Medical University were enrolled retrospectively from March 2010 to October 2011. The age and sex were matched in the 3 groups. All the clinical data of subjects were colleted in detail and then were compared and analyzed. Results (1)The Hcy levels (μmol/L)of group A,B,and C were 15. 10 (12. 43, 19.47),15. 80 (13. 10,20. 83),and 13. 20 (11. 00,16. 50;median [interquartile range]),respectively. There were significant differences among the 3 groups (P<0. 05). The incidences of hyperhomocysteinemia (HHcy)were 92. 8%(n=297),97. 1%(n=301),and 84. 7%(n=277)(P<0. 05). (2)Multivariate Logistic regression analysis showed that the independent risk factors for ACI were HHcy (OR 8. 97,95% CI 3. 01-26. 71),hypertension,diabetes,hyperlipidemia and blood ureanitrogen;the independent risk factors for AMI were HHcy (OR 4. 36,95% CI 1. 70-11. 21),hypertension,diabetes,hyperlipidemia,and total blood cholesterol. Conclusion HHcy is an independent factor for ACI and AMI,which have closer relationship with ACI. ACI and AMI have some common risk factors,but their degrees of action are different.

Objective To explore the effect of diabetic liaison nurses on controlling blood sugar levels in patients with hyperglycemia in department other than endocrinology. Methods Four hundred diabetic patients with high blood sugar were selected from January to December, 2014 in department other than endocrinology. They were divided randomly into 2 groups equally:the control group and the observation group. The control group received traditional nursing care, while blood sugar management was carried out by diabetic liaison nurse in the observation group. Result Pre-discharge sugar metabolism in the observation group was significantly better than that in the control group (P<0.05). Conclusion The diabetic liaison nurses in other departments than the endocrinology department can help control blood sugar levels in patients with hyperglycemiain.

The study was aimed to investigate the application value of interphase fluorescence in situ hybridization (FISH) on cell smears in hematological diseases. Both interphase FISH on peripheral blood smears and bone marrow smears treated by methanol/acetic acid, and routine interphase FISH of bone marrow cells dropped on slides were done at the same time, in order to detect Ph chromosome by BCR/ABL dual color, dual fusion probe in 20 patients with chronic myelogenous leukemia or acute lymphoblastic leukemia which had been proven to display Ph chromosome positive. The results indicated that as compared with routine interphase FISH, the interphase FISH on cell smears could also offer reliable result. It is concluded that interphase FISH on cell smears is a kind of reliable and time-saving technique, which is also suitable for retrospective research and worthy to further apply in clinic.

The objective of study was to evaluate the clinical values of multiparameter flow cytometry (MPFC) and cytomorphology of bone marrow aspiration(BMA) in detecting bone marrow involvement in patients with B cell Non-Hodgkin's lymphoma (B-NHL). 96 bone marrow samples from the patients with B-NHL were measured by MPFC using CD45/SSC and CD20/SSC gating strategy combined with anti-kappa and anti-lamda monoclonal antibodies, and then compared with results acquired by cytomorphologic analysis of BMA. The results showed that the bone marrow involvement was confirmed by MPFC in 38 cases (39.6%), while it was detected by cytomorphologic analysis of BMA only in 12 cases (12.5%). There was a significant difference between the two methods (p<0.05). 12 positive cases detected by cytomorphologic analysis of BMA were also positive by MPFC. There was no difference of 3-year overall survival rate between negative and positive cases detected by MPFC, but their 4-year overall survival rate was 73.18+/-6.65% and 44.13%+/-19.55% respectively (p<0.05). It is concluded that the MPFC is a more sensitive method for detecting bone marrow involvement in patients with B-NHL than cytomorphologic analysis of BMA. The 4-year overall survival rate of the patients without bone marrow involvement was significant higher than those of patients with bone marrow involvement. Bone marrow involvement in B-NHL detected by MPFC can be useful for clinical evaluation and prognosis prediction.
