Traditional Chinese medicine (TCM) is an important part of modern medicine. Application of modern ana-lytical techniques to identify the authenticity of TCM and evaluate its quality is an important and critical content in the process of the modernization and internationalization of TCM. This paper described the development and charac-teristics of a 1H-NMR-based metabolomics technology, and reviewed its application in the species identification, quality evaluation of Daodi Y aocai (i.e., genuine medicinal materials), processing theory and the best harvest time of TCM. Besides, based on previous work, further discussion was given on technical methods and key question of the 1H-NMR metabolomics method. This paper provided a methodological reference for the species identification and quality evaluation of TCM and other herbal medicines.

Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

Objective To study the cause and treatment of chronic instability of the elbow.Methods Between August 1998 and August 2002,12 patients with chronic instability of the elbow were treated in our de- partment:They underwent complete medical check-ups and imaging examinations.Surgical exploration was done to determine the causes of their conditions.Their radial and(or)ulnar collateral ligaments were repaired respectively or simultaneously through the medial and lateral approaches for all the patients.All the patients were followed up for two to six years,with an average of three years.Results The follow-ups revealed no recurrent dislocation of elbow in this group.The stress valgus test and lateral pivot shift test(PST)were negative for all the patients.No elbow pain occurred.The mean flexion and extension of elbow ranged from 0 to 135?.The mean pronation was 85?and mean supination 80?.According the evaluation system of Chinese Medical Association,eight cases were rated as excellent and four as fine,with the excellent and fine rate of 100%.Conclusions Lesions of radial and(or) ulnar collateral ligaments are the major cause for chronic instability of the elbow.Surgical reconstruction of the collateral ligaments can obtain good effects in treatment of recurrent dislocation of the elbow.

The incidence of hypoglycemic events in patients with type 2 diabetes around the period of fasting in Ramadan was compared under the treatment with combined insulin glargine and glimepiride. The results showed that the number of hypoglycemic events in patients with type 2 diabetes before, during and after the period of fasting in Ramadan was not different (P=0.238).

Objective To review the clinical and pathologic features of xanthogranulomatous cystitis (XC). Methods The clinical and pathologic data of 3 patients (2 females and 1 male, mean age, 37.3 year, age range, 24-50 year) with XC were reported in combination with review of the relevant literature. All 3 cases had recurrences cystitis-like symptoms, 2 cases had lower abdominal pain.1 case found low abdominal palpable mass during physical examination. Ultra sonography and CT revealed solid mass at the dome of the bladder. Partial cystectomy was performed on 2 patients, the rest 1 was case treated as urachal carcinoma.Results Postoperative pathology confirmed XC. Pathological features were as follows: xanthoma cells (lipidladenmacrophages), multinucleated giant cells and cholesterol clefts. With 12-36 (mean 28) months follow-up, there was no recurrence and cystitis-like symptoms on these patients. Conclusions XC is a rare disease. XC is usually identified by pathology. The presence of a concomitant neoplasm should be considered when the diagnosis of XC is made.Surgical resection could be a curative treatment.

Objective To investigate the value of Cytochrome P450 (CYP3A5) * 3 gene polymorphism in providing individualized administration for the use of tacrolimus (Tac) in renal transplantation recipients.Method Pyrophosphate sequencing method was used to determine the CYP3A5 * 3 genotype of renal transplant patients in the first day after surgery.Sixty recipients were divided into experiment group and control group.Both groups of patients were routinely given the initial dose of Tac-4.0 mg/day in the first day after surgery.The experiment group of patients were given different doses of Tac based on the different CYP3A5 * 3 genotypes at the third day after surgery [for AA:0.12 mg/(kg· day),and for GG:0.06 mg/(kg· day)],and the control group of patients were given different dosages of Tac according to drug concentration.Different parameters were compared between two groups of patients:percentage of patients reaching the target concentration (3-8 μg/L) at the fifth day after surgery,days required to reach the target concentration level,times needed to adjust the dosage of Tac within two weeks.Result The percentage of patients reaching the target concentration in experiment group and control group was 90％ and 46.67％,respectively (P＜ 0.05).Days required to reach the target concentration were (3.67 ± 1.32) and (7.57 ± 3.42) on average,respectively (P ＜ 0.05).Times of adjusting the Tac dose in experiment group was significantly less than those in the control group (P＜0.05).In the experiment group,the target concentration was obtained even without dosage adjustment (70％).Conclusion Individualized adjustment of Tac doses for patients according to recipients' different CYP3A5 * 3 genotypes is beneficial for reaching target concentration as soon as possible,which is superior to traditional dosage regimen.

Objective To investigate the effects of ATP1A1 knockdown by RNA interference(RNAi) on proliferation of human U251 glioma stem cells .Methods The human U251 glioma stem cells were infected with lentivirus expressing ATP1A1-shRNA . The mRNA and protein expressions of ATP1A1 in U251 glioma stem cells were detected by RT-qPCR and Western blotting ,re-spectively .The cell cycle and apoptosis were evaluated by flow cytometry .The proliferation of U251 glioma stem cells was deter-mined by MTT assay .Results The expressions of ATP1A1 in U251 glioma stem cells transfected with ATP1A1-shRNA were in-hibited significantly at both mRNA and protein levels ,with an inhibitory rate of 84 .15% for ATP1A1 mRNA and of 55 .33% for ATP1A1 protein respectively .The proliferation of cells was inhibited ,the cell apoptotic rate was significantly increased and the cell cycle was arrested in G1 phase and S phase decreased significantly in ATP1A1-shRNA cells(P<0 .05) .Conclusion RNAi targe-ting ATP1A1 gene could down-regulates the ATP1A1 expression ,induces cell apoptosis ,regulates cell phase redistribution and in-hibits cell proliferation in U 251 glioma stem cells .
