OBJECTIVEWith functional magnetic resonance imaging (fMRI), cerebral function imaging of acupuncture and sham acupuncture at Taichong (LR 3) in patients with essential hypertension (EH) was observed to analyze central mechanism of Taichong (LR 3) to treat EH.

METHODSEighteen EH patients were divided into a twisting acupuncture group (10 cases) and a sham acupuncture group (8 cases), which were treated with twisting manipulation and sham acu- puncture at right Taichong (LR 3), respectively. The treatments were both given with 30-second manipulation and 30- second interval for totally 5 min. During the acupuncture, fMRI was adopted to scan the cerebral function imaging of EH patients on resting state, and the acquired data were analyzed with SPM2 module in Matlab software.

RESULTSAcupunc- ture at Taichong (LR 3) in EH patients mainly increased opposite-side oxygen consumption, which generally activated left anterior cingulated gyrus (BA 32), left inferior parietal lobule (BA 40), left inferior temporal gyrus (BA 19), left middle temporal gyrus (BA 37) and right anterior central gyrus (BA 6). The activated areas were related to motor, vision and cognition of emotion. Stimulation region of sham acupuncture mainly included right anterior cingulated gyrus (BA 24), left inferior parietal lobule (BA 40) and left inferior frontal gyrus (BA 7).

CONCLUSIONThe central mechanism of Tai- chong (LR 3) on antihypertensive effect and symptom improvement is not in thalamus and medulla that are traditionally believed to control blood pressure. Taichong (LR 3) could activate anterior cingulated gyrus to regulate parasympathetic nerve and lower blood pressure, and through anterior cingulated gyrus, the connection with the surrounding areas is strengthened to improve the cognitive impairment caused by long-term hypertension.

Objective To understand the current situation of statistical management of TCM;To analyze existing problems; To provide references for policy formulation and measure implementation for statistical management of TCM. Methods Literature research, field research, comparative analysis, questionnaire surveys, expert consultation, and Fisher's exact test were used in the study. Results It was found that China’s statistical management of TCM had the problems of imperfect system, unestablished investigation system, incomplete statistical index system, and nonstandard statistical management. No statistical difference was found in the three regions of east, middle and the west. Conclusion Management and investigation system should be established in statistical management of TCM; pilot projects should be conducted before they are spread;information sharing and data mining should be strengthened.

ObjectiveTo explore the effect of estrogen on osteoblast apoptosis induced by serum hungry in vitro.MethodsOsteoblasts of second or third generation from newly born SD rats calvaria were divided randomly into the control group, serum hungry group and serum hungry with estrogen group. Cells of each group were incubated for 24 h, 48 h, 72 h, 5 d, 7 d and 14 d, then labeled using TUNEL staining and examined for morphological characteristics of apoptotic cell under light microscopy after incubated for 72 h. The rates of apoptotic cells of each group were examined with flow cytometry.ResultsThe cells of the control group showed normal appears, the serum hungry group had many cells with purple and blue particles in nuclei, but serum hungry with estrogen group had less such cells. The rate of apoptotic cell significantly increased in serum hungry group and decreased in serum hungry with estrogen group compared with the control group examined with flow cytometry (P<0.05).ConclusionEstrogen can repress osteoblasts apoptosis of rats induced by serum hungry.

OBJECTIVETo compare the clinical effects of the circumcision stapler, circumcision cerclage, and traditional circumcision in the treatment of phimosis and redundant prepuce.

METHODSUsing the circumcision stapler (group A), foreskin cerclage (group B), and traditional circumcision (group C), we treated 276 patients with phimosis or redundant prepuce. We made comparisons among the three groups in the operation time, intraoperative blood loss, intraoperative and 24-hour postoperative pain scores, and incidence of postoperative complications. Results: The operation time, intraoperative blood loss, and intraoperative pain score were (6.52 ± 2.45) min, (1.93 ± 0.82) ml, and 1.37 ± 0.68 in group A and (7.24 ± 1.86) min, (1.51 ± 0.72) ml, and 1.20 ± 0.79 in group B, all significantly lower than (28. 36 ± 4.22) min, (9.52 ± 3.29) ml, and 3.06 ± 0.75 in group C (P <0.05). The 24-hour postoperative pain score was remarkably higher in group B than in A and C (3. 18 ± 0. 82 vs 1. 85 ± 0. 63 and 1. 82 ± 0. 75, P <0. 05). The incidence rate of postoperative complications was markedly lower in group A than in B (5. 43% vs 14. 13%, P < 0.05), but with no significant differences between either A and C or B and C (P >0.05).

CONCLUSIONThe circumcision stapler, with its advantages of simple operation, minimal invasiveness, fewer complications, and better cosmetic result, deserves a wider clinical application.

OBJECTIVETo observe the inhibiting effect of acupuncture on blood lipid, myocardial hypertrophy and fibrosis in mice with hyperlipemia, and explore its possible action mechanism.

METHODSTen inbred mice (C57) were applied. Forty ApoE(-/-) mice who removed gene of apolipoprotein E were randomly divided into a control group, a non-acupoint group, an acupoint group and a medication group. The points 0. 5 cm and 1 cm next to the end of mice tail were respectively punctured in the non-acupoint group; "Neiguan" (PC 6) and "Fenglong" (ST 40) were punctured in the acupoint group; intragastric administration of simvastatin was applied in the medication group. After 8 weeks of treatment, the changes of total cholesterol (TC) and ratio of heart to body mass in each group were measured; changes of cardiac muscle fiber and ventricular wall thickness were observed; enzyme linked immunosorbent assay (ELISA) was used to test the level of angiotensin II (Ang I ) in plasma, and western blotting method was used to test protein content of angiotensin II type 1 receptor (AT1R) and endothelin-1 type A receptor (ETAR) in the heart.

RESULTSAfter 8 weeks of intervention, compared with the control group, rising range of blood lipid was obviously decreased (P<0.01) in the acupoint group and medication group, ratio of P<0.01), myocardial heart to body mass was decreased (P<0.05), thickness of ventricular wall was reduced (P fibrosis was relieved, levels of Ang II and ET-1 in plasma were decreased (P<0. 05), content of NO was increased (P<0. 05), and protein content of AT1R and ETAR was decreased in the heart (P<0. 05).

CONCLUSION40) could inhibit the rising of blood lipid in ApoE(-/-) mice, lower the levels of Ang II and ET-1 in peripheral blood, increase the content of NO and inhibit the expression of AT1R and ETAR in heart tissue, which could relieve myocardial hypertrophy and fibrosis to play a protective role on heart.

MP-Rep fusion gene which size is about 1000bp was constructed by recombinant PCR technique.In order to construct fusion gene,Tobacco mosaic virus(TMV) partial movement protein gene(MP) and Cucumber mosaic virus(CMV) partial replicase gene(rep) were ligated.Two copies of MP-Rep fusion gene were ligated with soybean intron in inverted repeat manner,the recombinant fragments were then inserted into binary vector pBIN438 under the control of 35S promoter.Recombinant clone pBIN438-MP-Rep(i/r) which contained two different virus derived genes was constructed.Recombinant clone pBIN438-MP-Rep(i/r) in accord with expected design was certified by restriction endonuclease enzymes digestion and PCR analysis.This approach provides a basis for Broad-spectrum plant virus resistance mediated by RNA Silencing.

Objective To explore the expression and regulatory mechanism of hypoxia inducible factor-1?(HIF-1?)during fracture healing. Methods Mouse models of tibia fracture healing were established,and callus samples were collected 1,3,7,14,21 and 28 days after fracture.The development of callus and new bone formation were evaluated with roentgenology,Micro-CT and tetracycline double labeling method,and the expression of HIF-1?,vascular endothelial growth factor(VEGF),Runx2 and ALP in callus were detected with RT-PCR,Western blotting and immunohistochemistry.The relationship between HIF-1? and fracture healing was analysed. Results The expression of HIF-1? was detected in cells in the fracture sites as well as in evolved osteoblasts,chondrocytes and osteocytes in early callus under hypoxia.The highest expression rate of HIF-1? achieved on the 7th day after fracture,lasted for about 7 days,then decreased gradually,and returned to intact level on the 28th day after fracture.The expression tendency of VEGF resembled that of HIF-1?.Bone formation activity was more active in early callus,and the callus volume peaked on the 14th day after fracture and decreased gradually.The mineralization of callus mainly took place in the late healing period(14th to 28th day after fracture).Conclusion Cells involved in fracture healing are hypoxia-responsive cells,which express HIF-1?.HIF-1? can regulate cell state and function,and can promote angiogenesis so as to play a crucial role in fracture healing.
