Professor XIE Qiang's Tihu Guanding needling method, a kind of acupuncture method which takes acupoints of the Conception Vessel as the primary and acupoints of the Governor Vessel as the secondary. Acupoints Lianquan (CV 23), Tiantu (CV 22), Qihai (CV 6), Zhongwan (CV 12), Baihui (GV 20) and Dazhui (GV 14) are adopted as the basic ones. Other points can be added according to various symptoms, for instance, Yingxiang (LI 20) and Yintang (GV 29) for rhinopathy, Tinggong (SI 19) and Yifeng (TE 17) for otopathy, Yan'an (Professor XIE's experience) and Shanglianquan (EX-HN 21) for pharyngopathy and Kaiyin 1 (Professor XIE's experience) and Kaiyin 2 (Professor XIE's experience) for laryngopathy. During the needle retention, rotation manipulation should be done every 5 min at Lianquan (CV 23). And the patient should be told to put the tip of one's tongue at the the palate as well as to do deep breathing to communicate the Conception Vessel and the Governor Vessel. Moxibustion is adopted at Yongquan (KI 1) to induce the up floating fire to mingmen (where the primary yang is stored). The therapeutic effect on treatment of persistent otorhinolaryngologic diseases with the above mentioned method is approve to be good.

AIM:To investigate the potential of hematopoietic stem cells(HSCs)derived from mouse embryonic stem cells(ESCs)to reconstruct hematopoiesis in vivo.METHODS:Using a three-step method,a mice embryonic stem cell line,E14.1 was induced into hematopoietic stem cells.The cell markers with CD34+/Sca-1+ were identified by flow cytometry analysis,then HSCs(1?109 cells/L)from third-step were injected into SCID mice for observing teratoma formation.To validate function of HSCs,colonogenic cell assay was conducted and the hematopoiesis in lethally irradiated mice was reconstituted.RESULTS:The method of three-step differentiation,combined to use more hematopoietic stimulating factor promoted the E14.1 cell differentiation into HSCs with highest percent of CD34+/Sca-1+ cells(as high as 58.64%?4.20%)with more CFU-E,CFU-GM and CFU-GEMM populations.The cells showed the character of hematopoietic progenitors by Wright-Giemsa staining.Positive selected CD34+/Sca-1+ cells by magnetic sorting from third-step differentiation were transplanted into 7 lethally irradiated female mice while predominant hematopoietic reconstitution were observed in 10 d after transplantation,with 71.4%(5/7)successful engraftment rate.Three recipients showed that the cell population of the peripheral blood leukocytes,red blood cells and hemoglobin approached to normal index at 40 d after transplantation,but followed relative slow renew in platelet count.Survival rate in transplant group was 43%,compared to 100% mortality in control mice.Karyotyping assays confirmed the female mice with XY.CONCLUSION:The three-step differentiation and the culture conditions described here support the differentiation of mouse ESCs into HSCs.HSCs derived from mouse ESCs can reconstruct hematopoiesis.

BACKGROUND: Embryonic stem cells (ESCs), the seed cells of all mature cells in vivo, are useful tools for nerve transplantation and developmental gene function research. Notch1 signaling pathway is the key pathway to control the ordered neural development and differentiation of many kinds of neural cells, however, there is no report on the dynamic expression of Notch1 signal during the ESC differentiation to date. OBJECTIVE: To investigate the expression of Notch1 protein, transmembrane signal transduction molecule, during directional differentiation of embryonic stem cells into neural cells. DESIGN, TIME AND SETTING: Cell research was carried out between October 2003 and October 2004 at Zhongshan Ophthalmic Center, SUN Yat-sen University, Guangzhou, Guangdong Province, China. MATERIALS: BALB/C mouse embryonic stem cell line Ⅵ (passage 11)was obtained from experimental animal center of SUN Yat-sen University, provided by professor Huang Bing. ESC culture medium was high-glucose DMEM medium with 20% bovine serum and 106 IU/L mouse leukemia inhibitory factor. Induced differentiation medium was high-glucose DMEM medium with 20% fetal bovine.serum and 5×107 mol/L retinoid acid(RA). METHODS: Passage 11 ESCs were resuscitated and incubated by ESC culture medium in incubator at 37℃ with 5% CO2. Passage 11 ESCs were subcultured after 2 or 3 days and RA was added into medium to induce differentiation. Three time points for observation were established: induced for 1, 5 and 9 days. MAIN OUTCOME MEASURES: Morphological changes were observed under inverted phase contrast microscope, MAP-2 antigen expressed in differentiated cells was detected by immunofluorescence method. Immunocytochemistry, Western Blot, flow cytometry assay were used to investigate the Notch1 protein expression. RESULTS: ESCs presented clone-like growth. After induced by RA for 9 days, single neural network was achieved around most of the cell clusters. With the prolongation of induction, MAP-2 positive neural cells increased gradually. Almost all ESC clones expressed Notch1 protein strongly or positively, but Notehl protein expression decreased gradually after induced differentiation (P < 0.01). CONCLUSION: Notch1 signal shuts off progressively during induction of ESCs into neural cells, which suggests Notch1 may play an important role in the differentiation of ESCs into neural cells.

Objective To study the current incidence of Keshan disease in Yunnan Province,and provide scientific basis for Keshan disease(KD) prevention and control. Methods Based on the Scheme of KD Surveillance, 16 villages in 11 counties were chosen as surveillance sites by the historical data. An survey was made to the residents in the 16 surveillance sites by filling in the questionnaire, inquiry medical history, clinical examination, electrocardiogram and 2 meters post-anterior chest X-ray for suspected cases. KD cases were diagnosed according to the Diagnostic Criteria for Keshan Disease(GB 17021-1997). The prevalence data of KD in the whole province were collected from the KD case report in 2007 and the trace surveys. Results There were 6877 residents in 16 surveillance sites of 11 surveillance counties and totally 39 KD cases were diagnosed with a detection ratio of 0.57% (39/6877). The detection ratio of latent and chronic KD were 0.41%(28/6877) and 0.16%(11/6877), respectively and no acute or subacute cases were found. The cases aged 5 to 14 years old accounting for 66.67% (26/39). Electrocardiogram examination of 6877 residents were made and 5.25% (361/6877) abnormal electrocardiograms were detected in the 16 surveillance sites. Fifty-five people were checked by chest X-ray and there were 31 cases with heart-chest ratio ≤0.50, 16 cases with heart-chest ratio from 0.51 to 0.55 and 8 cases with heart-chest ratio from 0.56 to 0.60. The prevalence rate and incidence rate of chronic KD were 4.24 per 100 000 and 0.50 per 100 000 in Yunnan. No acute or subacute cases were found and the latent cases were listed. The prevalence rate and incidence rate were 7.76 per 100 000 and 1.18 per 100 000 in the 16 surveillance sites. Conclusions The incidence of KD is low incidence in Yunnan Province. Higher ineidence of chronic KD was detected in the some areas and the corresponding control measures need to be adopted.

Objective In order to master the current situation of Keshan disease in Yunnan province and to provide scientific basis for Keshan disease control and prevention. Methods Eighteen villages were selected as the investigation sites in 6 counties across all the Keshan disease wards in Yunnan province,where the residents were investigated. Then,the villages census data was collected,clinical examination aiming mainly on cardiovascular system was carried out,including electrocardiography and X-ray to the suspected patients. Correct diagnose of Keshan disease was made by the Diagnostic Standard of Keshan Disease(GB 17021-1997). At the same time,10 food samples and 10 hair samples for detecting selenium content in every investigation site. Results There were 9818 residents investigated in the 18 investigation sites in 6 counties,and 34 eases of Keshan disease were found,the total incidence rate was 0.35%(34/9818). Among the 34 Keshan disease eases,32 cases were latent Keshan disease,the incidence rate was 0.33%(32/9818); 2 cases were chronic Keshan disease,the incidence rate was 0.02%(2/9818). There was no any acute and sub acute cases be found. Most Keshan disease cases aged from 5 to 14,67.65% (23/34). Abnormal ECG rate was 6.90% (677/9818). Among 56 X-ray films,47 cases had a cardiothoracic ratio less than or equal to 0.50,83.93%(47/56),5 cases from 0.51 to 0.55,8.93%(5/56),4 cases from 0.56 to 0.60,7.14%(4/56). Selenium content was detected in 180 food samples and 180 hair samples. The average food selenium content (mg/kg) was 0.013±0.010,the lowest content in Yongsheng county (0.006± 0.001),the highest content in Tonghai county(0.027±0.009). The average hair selenium eontentwas(0.252± 0.078)mg/kg,with the lowest(0.145±0.043)mg/kg in Yoagsbeng county,the highest (0.297±0.062)mg/kg in Tonghai county. Conclusions The detected ratio of Keshan disease is low in Yunnan province. Most of Keshan disease patients age from 5 to 14. It was presented that the Keshan disease infectious agents were still strong and active. The foodstuffs and hair Selenium content is low in food and hair sample,and varies in different investigation site. It is necessary to supply selenium for prevent Keshan disease in the severe areas.
