Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1％) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5％ in acupoint application group 1, versus 62.5％ in acupoint application group 2 and 55.0％ in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0％ in acupoint application group 1, versus 70.0％ in acupoint application group 2 and 65.0％ in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).

Objective To investigate the effect and mechanism of transplantation of marrow multi- function stem ceils in treating femoral head necrosis.Methods Sixty japanese rabbits were divided into A,B and C groups randomly.After creation of the models of hormone induced necrosis of femoral head;A group was designated as the treatment,B as the control and C as the normal groups.The bone marrow of A group was extracted and isolated and then injected into the left femoral head and the right femoral head was decompressed by drilling only.The rabbits were killed at 8 weeks after the treatment and changes in various parameters were observed,including imaging data of molybdenum target films,CT and MRI;routine pathology with HE staining and ultrastructural alteration by election microscopy.Results Eight weeks after the treatment of transplantation of marrow multifunction stem cells,the X-ray showed only a little change but the typical appearances were revealed by CT and MRI.Pathohistologic manifestation demonstrated decrease of empty bone lacuna,increase of osteoblast and new bone formation.Election microscopy displayed abundant organelles in osteoblasts with few empty bone lacuna,in addition the tansplantation of marrow multifunction stem cells could obtain better reconstraction for the involved femoral head.Conclusions The treatment of transplantation of marrow muhifunction stem cells in femoral head necrosis could accelerate the process of repairing,worthy to be acknowledged as a good and valuable management in rabbits.(J Intervent Radial,2007,16:122-126)

Background Surgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP).Two major strategies exist:duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD).Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however,the long-term effects have not been thoroughly investigated.We analyzed the long-term outcomes of DPPHR and PD,over follow-up times of at least 1 year,to determine the optimal surgical treatment for CP.Methods We systemically reviewed all CP surgical treatment reports,and only included randomized controlled trials (RCT) comparing DPPHR and PD,excluding unqualified studies using several pre-specified criteria.When multiple publications of a single trial were found,the most comprehensive current data were selected.Characteristics of the study populations and long-term postoperative outcome parameters were collected.The quality of the studies and data was analyzed using RevMan 4.2 software.Results Five trials were qualified for meta-analysis,with 261 participants in total (114 in the DPPHR group and 147 in the PD group).There were no significant differences in the age,gender,or indications for surgery of each group.At the mean of 5.7-year (1-14 years) follow-up examination,DPPHR and PD resulted in equally effective pain relief,exocrine and endocrine function,and similar mortality rates (P ＞0.05); however,DPPHR patients had improved global quality of life and weight gain,and reduced diarrhea and fatigue (P ＜0.05).Conclusion DPPHR and PD result in equal pain relief,mortality,and pancreatic function; however,DPPHR provides superior long-term outcomes.

OBJECTIVETo establish a microemulsion liquid chromatography system with direct sample loading for determining the serum level of emodin in rats.

METHODSThe separation was performed on C₁₈ column (Hypersil BDS, 5 µm,150 mm×4.6 mm) with the microemulsion mobile phase consisting of 3.3% (w/V) SDS, 6.6% (V/V) n-butyl alcohol, and 1.0% (V/V) octane and water. The flow rate was 1.0 ml/min and the detection wavelength was 254 nm.

RESULTSThe linear range of emodin detection was 0.333-5.32 µg/ml. The average recovery was 99.65% with a RSD of 3.60%. The limit of quantification was 0.1386 µg/mL.

CONCLUSIONMicroemulsion liquid chromatography system with direct sample loading allows simple, accurate and rapid determination of emodin in rat serum.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

Objective To observe the efficacy of hybrid balloon valvuloplasty for the treatment of low-body weight infants with severe congenital valvular aortic stenosis ( AS ).Methods Five infants with severe congenital valvular aortic stenosis underwent the hybrid balloon aortic valvuloplasty through median sternotomy in the hybrid operating room.The mean age was (40.2 ± 7.0) days,weight was (4.48 ± 0.75 )kg.The patients were followed up by echocardiography for 9 - 13 months post procedure.Results Operation was successful in all 5 patients and they were discharged from hospital uneventfully.The gradient pressure decreased significantly from (98.8 ±9.0)mm Hg( 1 mm Hg =0.133 kPa) to ( 13.8 ±3.3) mm Hg (P ＜0.05)post operation. There was no moderate or severe aortic insufficiency. All patients were alive,the gradient pressures was ( 18.8 ± 2.5) mm Hg and there was no moderate or severe aortic insufficiency during follow-up [ 9 - 13 (11.0 ± 1.4) months ].Conclusion The hybrid balloon aortic valvnloplasty is an effective option for the low-body weight infants with severe congenital valvular aortic stenosis.

BACKGROUNDSurgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP). Two major strategies exist: duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD). Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however, the long-term effects have not been thoroughly investigated. We analyzed the long-term outcomes of DPPHR and PD, over follow-up times of at least 1 year, to determine the optimal surgical treatment for CP.

METHODSWe systemically reviewed all CP surgical treatment reports, and only included randomized controlled trials (RCT) comparing DPPHR and PD, excluding unqualified studies using several pre-specified criteria. When multiple publications of a single trial were found, the most comprehensive current data were selected. Characteristics of the study populations and long-term postoperative outcome parameters were collected. The quality of the studies and data was analyzed using RevMan 4.2 software.

RESULTSFive trials were qualified for meta-analysis, with 261 participants in total (114 in the DPPHR group and 147 in the PD group). There were no significant differences in the age, gender, or indications for surgery of each group. At the mean of 5.7-year (1 - 14 years) follow-up examination, DPPHR and PD resulted in equally effective pain relief, exocrine and endocrine function, and similar mortality rates (P > 0.05); however, DPPHR patients had improved global quality of life and weight gain, and reduced diarrhea and fatigue (P < 0.05).

CONCLUSIONDPPHR and PD result in equal pain relief, mortality, and pancreatic function; however, DPPHR provides superior long-term outcomes.

OBJECTIVETo study the expression level and significance of glucose transporter 1 (Glut-1) in normal breast tissue, adenosis, adenoma and breast carcinoma.

METHODSA total of 147 cases of female breast tissue samples, including 92 cases of invasive ductal carcinoma, 26 cases of breast fibroadenoma, 24 cases of breast adenosis and 5 cases of normal breast tissues, were collected for quantitative detection of the expression of Glut-1 protein by immunohistochemistry (EnVision method) and Western blot, and its mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSIn normal breast tissue and benign lesions of the breast, Glut-1 was undetectable or only weakly detectable in cytoplasm of ductal and acinar epithelia. In contrast, the intensity of Glut-1 staining was significantly higher in invasive ductal carcinomas (P = 0.0002) with protein expression predominantly in cellular membrane and lesser in cytoplasm. Western blot and RT-PCR analyses showed that the expression of Glut-1 protein and mRNA were significantly increased in invasive ductal carcinoma than fibroadenoma (P =0.001 for protein; P <0.05 for mRNA) and adenosis (P =0.001 for protein; P < 0.05 for mRNA). There was a significant difference among groups (P = 0.0002 for protein; P = 0.0001 for mRNA).

CONCLUSIONSGlucose transport activity, as indicated by Glut-1 protein and its mRNA expression, significantly increases in breast carcinoma than non-cancerous lesions. The over-expression of Glut-1 in breast carcinoma is tightly coupled with tumor cell proliferation, invasion and metastasis, implying that Glut-1 may serve as a new marker in the early diagnosis and prognostication of breast malignancy as well as a new therapeutic target.

Sanqi in Chinese herbal medicine is the root and rhi-zoma of Panax notoginseng (Burk.)F.H.Chen. As the effects of strengthening with tonics, promoting blood circulation to re-move blood stasis,relieving swelling and pain and hemostasia,it is widely used as a tonic medicine in the traditional Chinese medicine. The main active constituents of Sanqi are panax noto-ginseng saponins,including ginsenoside Rg1,Rb1 and notogin-senoside R1. Notoginsenoside R1 is one of the unique monomer compositions of panax notoginseng,which is often used as an in-gredient indicator in new drug research and development.In cur-rent years, the scientists have been conducted tremendous fun-damental studies to research the pharmacological activities of no-toginsenoside R1, to reveal its protective effects on the cardio-vascular system,central nervous system as well as to many other aspects. It is hoped that the relevant study about the pharmaco-logical action of notoginsenoside R1 would help its further clini-cal application. This paper mainly reviews the research on the pharmacological mechanism of notoginsenoside R1 in recent years.
