A quantitative analysis method of multi-components with a single marker (QAMS) for simultaneous determination of six marker compounds (one from phenolic acids and five from phthalides) in Chuanxiong Rhizoma was established by applying HPLC and using butylidenephthalide as the internal reference substance. And also the feasibility and accuracy of the established method for quality evaluation and application of Chuanxiong Rhizoma were investigated and validated. The analysis was performed with the mobile phase consisting of acetonitrile - 0.2% aqueous formic acid. The flow rate was 1.0 mL . min-1 and the column temperature was maintained at 30 °C. The detection wavelengths were set at 252 nm (for ferulic acid, Z-ligustilide, and butylidenephthalide) and 266 nm (for senkyunolide I, senkyunolide A, and coniferyl ferulate), separately, and 20 µL was injected for analysis with gradient elution. The results showed that there were no significant differences observed between the HPLC-QAMS method and the external standard method (RSD <5%). The relative correction factors were credible (RSD < 5%) in changed chromatographic conditions. The established HPLC-QAMS method can be accurately used for simultaneously evaluating and controlling the quality of Chuanxiong Rhizoma with multi-components.

This study examined the effect of insulin on the expression of very low density lipoprotein receptor (VLDLR) subtypes of SGC7901 cells and discussed its biological implication. In vitro, moderately or poorly-differentiated human gastric adenocarcinoma cell line SGC7901 was incubated with insulin for different lengths of time, and then the expression of protein and RNA level in VLDLR subtypes were detected by Western blotting and real-time PCR, respectively. The results showed that, at certain time interval, insulin could down-regulate expression of type I VLDLR and up-regulate the expression of type II VLDLR in SGC7901 cells, at both protein and RNA level. We are led to conclude that insulin serves as a regulator in maintaining the balance between glucose and lipid metabolism in vivo, possibly through its effect on the differential expression of VLDLR subtypes.

Objective To compare the influences of different dilution titers on the ANA detection by the indirect immunofluores‐cence assay(IIF) in children for investigating the necessity of reducing serum initial dilution titer .Methods Serum ANA was detec‐ted by using the indirect immunofluorescence assay at a serial of dilution titer in 110 healthy controls and the results were compared with the results of specific ANAs by the linear immunoassay (LIA);meanwhile the ANA‐LIA results in clinical children patients with ANA‐IIF negative were also analyzed .Results With the dilution titers gradual decrease from 1∶80 ,1∶40 and 1∶20 in the samples of the health group ,the positive detection rates of ANA‐IIF were risen ,which were 7 .3% ,9 .1% and 10 .9% respectively , but the differences were not statistically significant (P>0 .05) ,the weak‐positive rates were 7 .3% ,15 .5% and 31 .8% respective‐ly ,the differences were statistically significant (P<0 .01) .Among 110 healthy children under going the physical examination ,the specific ANA was detected out in 8 samples ,the positive rate was 7 .3% .Among 8 positive cases at the dilution titer of 1∶80 by the IIF method ,specific ANA was in 2 cases;in 4 added cases of fluorescence ANA positive samples at the dilution titers of 1∶40 and 1∶20 ,specific ANA was in 1 case .If with any positive of ANA‐IIF(1∶80) or ANA‐LIA as the ANA positive ,the ANA positive rate was risen from 7 .3% to 12 .7% .In the clinical samples among 29 cases of ANA‐IIF(1∶80) negative autoimmune liver disease related autoantibody detection ,the specific ANA‐LIA positive was detected in 5 cases (17 .2% ) .Conclusion Reducing the initial ti‐ter of children serum is unable to obviously increase the ANA‐IIF positive detection rate ,on the contrary increases the non‐specific weak positive .Therefore ,clinical laboratory does not change the dilution titer of children routine ANA sample .The detection by combining with the specific ANA‐LIA spectrum is conducive to find ANA .

To study the name of Wenyujin Rhizoma Concisum and Film Turmeric by literature research methods provide the basis for correct application of Cuba in modern clinical application. Wenyujin Rhizoma Concisum and Film Turmeric often called each other mutual generation and used as the same kind of medicine in the ancient prescriptions books. They were often recorded and stated as the same species of Curcumae Longae Rhizoma. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma also often called each other mutual generation in the ancient prescriptions books and used as the same kind of medicine. Wenyujin Rhizoma Concisum was often recorded and stated under the Curcumae Longae Rhizoma articles in the ancient materia medica literatures. Ancient literatures on Wenyujin Rhizoma Concisum records were almost the same, the modern literatures on the records of the sources of Wenyujin Rhizoma Concisum were inconsistency. Inconsistency of Wenyujin Rhizoma Concisum source records in modern literatures was related to the changes of the modern records on source records about Curcumae Longae Rhizoma, Root-tuber of Aromatic Curcumae Longae Rhizoma and Zedoray. The author thinks that Wenyujin Rhizoma Concisum is the ancient Film Turmeric which referes to the same medicine as Curcumae Longae Rhizoma. The source of it just as the Curcumae Longae Rhizoma is not only one kind. Wenyujin Rhizoma Concisum and Curcumae Longae Rhizoma have been recorded as two medicines at the present, and the source of them simply referes to the original plant Curcuma wenyujin. When using ancient prescriptions, we need to understand the changes that Curcumae Longae Rhizoma and Wenyujin Rhizoma Concisum are the same in ancient but different today in order to choose medicine correctly in the clinical.

Background and Objective Keshan disease is clinically characterized as a dilated eardiomyopathy. We analyze the prevalence trend during last decade of hypertension and Keshan-disease in Yangzhuang village which was a Keshan-disease epidemic area.Method The survey including medical history,blood pressure and ECG were carried out every two years during the follow up 13 years.Results During follow up period,the total detection rate(hypertension:13.4 % vs Keshan-disease:10.7 %,?~2=8.555,P=0.002)and the accumulative rate of hypertension were higher than those of Keshan-disease,which was on the contrary to that before 1993,when increasing rate of Keshan-disease was higher than hypertension.Furthermore,the accumulative increasing rate of hypertension was 240.0%,which was higher than the national average level during corresponding period with no significant differences between female and male.Conclusion The detection rate of hypertension in Keshan disease epidemic area was higher than the average rate nation-wide.Whether the hypertension prevalence was re- lated to Keshan-disease needs further investigation.

Background and purpose: The incidence of breast cancer increases as patients age, elderly patients account for a large proportion. Due to the insufifcient systemic therapy, more complications and poorly physical condition, the prognosis of elderly patients is often worse than the younger. The aim of this study was to investigate the safety and tolerance with non-anthracyclin regimen as adjuvant chemotherapy in elderly breast cancer patients. Methods:From Nov. 2008 to Jan. 2012, 56 patients (≥65 years) after surgical excision were enrolled into this study. The patients were divided into two groups:TC and PC groups. Each patient received 4 or 6 cycles of chemotherapy of PC (175 and 600 mg/m2, respectively;n=21) or TC (75 and 600 mg/m2, respectively;n=35), administered intravenously every 3 weeks, as adjuvant chemotherapy. Radiation therapy (as indicated) and endocrine therapy, for patients with hormone receptor-positive disease, were administered after completion of chemotherapy. Results: In this study, 50 patients completed chemotherapy as plan, the proportion of two groups were above 90%. After a median follow-up of 33 months, the median disease-free survival(DFS) and overall survival(OS) were not reached. The relapse-free rate and survival rate were 89.5%and 100%in the PC regime group, which were 90.3%and 96.8%in the TC regime group. Major toxicities included:neutropenia, leucopenia, alopecia, nausea, vomiting and various degree of peripheral neuropathy. The incidence of gradeⅢ-Ⅳneutropenia was 76.2%in PC group vs 48.6%in TC group (P=0.044). The most common cause for withdrawing from treatment was to be unable to tolerate the adverse effects. Conclusion:Adjuvant chemotherapy with paclitaxel and cyclophosphamide is safe, tolerable and promising for elderly breast cancer patients.

OBJECTIVETo observe the clinical efficacy on pain in postmenopausal osteoporosis treated with the warm acupuncture therapy and discuss its effect mechanism.

METHODSNinety cases of postmenopausal osteoporosis were randomized into a warm acupuncture group, an electroacupuncture group and a medication group, 30 cases in each group. In the warm acupuncture group and the electroacupuncture group, Dazhu (BL 11), Shenshu (BL 23) and Xuanzhong (GB 39) were selected bilaterally and stimulated with the warm acupuncture and electroacupuncture therapies respectively, once a day for 30 days totally. In the medication group, caltrate-D tablets were prescribed, 600 mg, once a day for 30 days totally. The changes in the bone density T value, visual analogue scale (VAS) score, serum insulin like growth factor 1 (IGF-1), interleukin 6 (IL-6) and tumor necrosis factor (TNF-alpha) were observed before and after treatment in the three groups.

RESULTS(1) The bone density T value in the patients of postmenopausal osteoporosis did not change obviously after 30 days treatment with the three therapies; (2) VAS score was all reduced after treatment, in which, the result in the warm acupuncture group was the most obvious (6.73 +/- 0.24 before treatment vs 4.43 +/- 0.26 after treatment). The value after treatment in the warm acupuncture group was different significantly as compared with the electroacupuncture group (5.13 +/- 0.31) and the medication group (5.17 +/- 0.33, both P < 0.05). (3) The level of serum IGF-1 was improved after treatment in the warm acupuncture therapy [(119.5 +/- 20.1) ng/mL before treatment vs (156.5 +/- 23.9) ng/mL after treatment], which was more apparent as compared with the electroacupuncture group [(136.3 +/- 24.5) ng/mL] and the medication group [(127.7 +/- 22.1) ng/mL, all P < 0.05]. Concerning to reducing the levels of IL-6 and TNF-alpha in serum, the results in the warm acupuncture group were superior to the other two groups (all P < 0.05).

CONCLUSIONThe warm acupuncture therapy achieves the significant efficacy on pain in postmenopausal osteoporosis, which could be related to increasing the level of IGF-1, decreasing the levels of IL-6 and TNF-alpha, promoting bone formation and inhibting bone absorption.

OBJECTIVETo identify potential mutation responsible for synpolydactyly (SPD) in a large Chinese kindred and to offer genetic counseling and prenatal diagnosis for the members of the family.

METHODSAll family members were examined clinically, and blood samples were obtained for linkage analysis and mutation screening. Ultrasound examinations were conducted at 16-21 weeks. Amniotic fluid sample was obtained by ultrasound-guided amniocentesis at 18 weeks of gestation.

RESULTSA large kindred affected with SPD was identified and characterized. With two short tandem repeat (STR) markers (D2S1238 and D2S1245) flanking the HOXD13 gene, the disease was mapped to 2q31. A heterozygous 27 bp expansion within the imperfect GCN triplet-repeat of exon 1, c. 184_210dup, was identified. The mutation resulted in a gain of 9 alanine residues between the 14th and 15th alanine of the normal 15-amino-acid-long polyalanine tract. On ultrasound examination, all fingers and toes of the fetus appeared to be normal. Linkage analysis and mutation detection confirmed that the fetus did not inherit the mutant allele from his affected mother.

CONCLUSIONHOXD13 gene mutation was responsible for the SPD phenotype in this family. Accurate prenatal diagnosis of SPD was achieved with combined ultrasound and molecular analysis.

Primary central nervous system germ cell tumors (CNS-GCTs) in children and adolescents have unique clinical features and methods of treatment compared with those in adults. There is little information about Chinese children and adolescents with CNS-GCTs. Therefore, in this study we retrospectively analyzed the clinical features and treatment outcome of Chinese children and adolescents with primary CNS-GCTs. Between January 2002 and December 2012, 57 untreated patients from a single institution were enrolled. They were diagnosed with CNS-GCTs after pathologic or clinical assessment. Of the 57 patients, 41 were males and 16 were females, with a median age of 12.8 years (range, 2.7 to 18.0 years) at diagnosis; 43 (75.4%) had non-germinomatous germ cell tumors (NGGCTs) and 14 (24.6%) had germinomas; 44 (77.2%) had localized disease and 13 (22.8%) had extensive lesions. Fifty-three patients completed the prescribed treatment, of which 18 underwent monotherapy of surgery, radiotherapy, or chemotherapy, and 35 underwent multimodality therapies that included radiotherapy combined with chemotherapy or surgery combined with chemotherapy and/or radiotherapy. PEB (cisplatin, etoposide, and bleomycin) protocol was the major chemotherapy regimen. The median follow-up time was 32.3 months (range, 1.2 to 139 months). Fourteen patients died of relapse or disease progression. The 3-year event-free survival (EFS) and overall survival rates for all patients were 72.2% and 73.8%, respectively. The 3-year EFS was 92.9% for germinomas and 64.8% for NGGCTs (P = 0.064). The 3-year EFS rates for patients with NGGCTs who underwent monotherapy and multimodality therapies were 50.6% and 73.5%, respectively (P = 0.042). Our results indicate that multimodality therapies including chemotherapy plus radiotherapy were better treatment option for children and adolescents with CNS-GCTs.
