Objective To investigate the current status, performance,challenges and demands of the health management service-related institutions in China so as to provide evidence for effective policy-making. Methods A cross-sectional study design was used in this report. The health management service-related institutions were identified based on web site searching and government business registration records. Web or mail-based questionnaire was used for data collection. Telephone interview was conducted to confirm the validity and reliability of the data. Results Of 5744 health management service-related institutions in China,585 were investigated for type of organization, personnel profile, business strategy and investment. Since 2000, the number of health management service-related institutions in China had kept increasing in an average rate of 52%. The services included physical check, health education, and disease intervention,etc. Conclusions In China,health management is still at its early stage although an increasing trend could be found and a large number of related- institutions have emerged. However, health management system in China still faces the challenge of poor professional services and insufficient healthcare providers.

Fluorescent staining method is a sensitive cytochemical staining method, it can reflect minimal changes of biochemical components of cells. The 7690-Xu fluorescent staining solution prepared with thioflavine can show the heterogeneo- us fluorescence of cells in different stages of differentiation. The younger cells with low degree of differentiation show blue fluorescence, the lower the degree the deeper the color. Along with the differentiation of cells, the blue color of fluorescence deflects to the red color of spectrum gradually, the blue color of fluorescence of cytoplasm changes gradually to bluish, bluish-green, and finally yellow color. The blue color of fluorescence of nucleus changes through greyish- blue to orangeyellow or orange-red.The cytoplasm of cells in various organs with high degree of differentiation appears yellow, and the nucleus orange-yellow or orange-red in color.

OBJECTIVETo observe clinical therapeutic effect of combined acupuncture and moxibustion therapy on polyneuritis.

METHODSOne hundred and sixty cases were treated with combined scalp acupuncture, body acupuncture (stimulating root of nerve as main), cupping and pricking at segmental root of nerve, and electric hot moxibustion, and their therapeutic effects were observed.

RESULTSOne hundred and thirty-eight cases were cured (86.3%) and the total effective rate was 100.0%. The average recovery time for clinical symptoms was 12.81 days, the average recovery time for nervous system signs was 19.76 days, the average recovery time for recovery of ocular muscular dyskinesia was 15.14 days.

Objective:To investigate the effect of astragaloside IV (AS-IV) on the secretion of stromal cell-derived factor-1α (SDF-1α) and CXC chemokine receptor 4 (CXCR4) by high glucose injured human umbilical vein endothelial cells (HUVECs), so as to lay a foundation for further study on AS-IV improving angiogenesis by regulating SDF-1 α/CXCR4 axis of endothelial cells.Methods:HUVECs were isolated and cultured from the umbilical vein of full-term healthy newborns and identified by von Willebrand factor (vWF) combined with 4-diamino-2-phenylindole (DAPI) nuclear staining. The obtained HUVECs was cultured in EGM-2 medium with 30 mmol/L glucose for 120 h to obtain high glucose damaged HUVECs. After intervention with different concentration gradients (25 mg/L, 50 mg/L, 100 mg/L, 200 mg/L, 400 mg/L) AS-IV for 72 hours, the contents of SDF-1α and CXCR4 were detected by enzyme linked immunosorbent assay (ELISA) method to determine the best concentration of AS-IV. The supernatant of damaged HUVECs were collected at 6, 12, 24, 48 and 72 hours after intervention with the best concentration of AS-IV, and the contents of SDF-1α and CXCR4 were detected by ELISA method to determine the best action time of AS-IV. The damaged HUVECs was randomly divided into experimental group and control group, and the blank group was set up at the same time. The experimental group was treated with the best concentration of AS-IV and the best time, the control group and the blank group were treated with the same volume of phosphate buffered saline (PBS) solution, and the contents of SDF-1α and CXCR4 in each group were detected by ELISA method.Results:The vWF factor on the cell membrane was green fluorescence, and the nucleus was blue after DAPI staining. When the fusion image showed green fluorescence, HUVECs were identified by blue fluorescence. The expression of SDF-1α in damaged HUVECs was the best when treated with AS-IV of 100 mg/L for 24 hours (1 642.87 pg/ml), and the expression of CXCR4 in damaged HUVECs was the best when treated with AS-IV of 50 mg/L for 48 hours (8.44 ng/ml). Compared with the control group, the contents of SDF-1α and CXCR4 in the experimental group were significantly increased, and the difference was statistically significant ( P<0.05). While the contents of SDF-1α and CXCR4 in the experiment group were slightly less than those in the blank group and there was no statistically significant difference ( P>0.05). Conclusions:AS-IV can promote the expression of SDF-1α and CXCR4 in HUVECs damaged by high glucose to return to normal physiological level, so as to play the role of vascular repair and neovascularization.

OBJECTIVETo explore the effects of gastrin on the expression of 1,25(OH)2D3-membrane associated rapid response steroid (1,25D3-MARRS) binding protein in rat intestinal epithelium.

METHODSSD rats received intraperitoneal injections of gastrin, omeprazole or physiological saline. The protein expression of 1,25D3-MARRS binding protein in SD rat intestinal was determined with Western blotting and immunohistochemistry, and its mRNA levels determined by RT-PCR. The serum calcium and phosphate levels in the rats were also detected.

RESULTSImmunohistochemistry showed that 1,25D3-MARRS binding protein was expressed mainly in the nuclei, cytoplasm and membrane of the intestinal epithelial cells. Both the protein and mRNA expression levels of 1,25D3-MARRS binding protein were up-regulated after treatments with gastrin and omeprazole (P<0.05), but the serum calcium and phosphate concentrations showed no obvious increase.

CONCLUSION1,25D3-MARRS binding protein, which is widely expressed with versatile functionalities, is regulated by gastrin and shows high potentials in the study of gastrointestinal diseases.

AIMTo propose a new simple and sensitive voltammetric method for determination of proteins.

METHODSProtein with sulfhydryl or disulfide bond in 0.5 mol x L(-1) NaOH, 1.5 x 10(-4) mol x L(-1) Pb2+ and 0.02% tetrabutylammonium iodide was heated in boiling water for 5 minutes. The reactive product gave a well defined reductive adsorption wave at -0.66 V (vs SCE) by means of single sweep polarography, and the height of derivative wave was proportional to the concentration of proteins.

RESULTSThe peak height was linearly proportional to bovine serum albumin (BSA) or human serum albumin (HSA) concentration in range of 7.5 x 10(-10) -3.0 x 10(-7) mol x L(-1) (r(BSA) = 0.9995, and r(HSA) = 0.9990). The detection limit of BSA or HSA was 3.0 x 10(-10) mol x L(-1). For lysozyme (Lyso), the concentration range was from 1.4 x 10(-8) to 1.3 x 10(-6) mol x L(-10 (r(Lyso) = 0.9997) and the detection limit was 7.0 x 10(-9) mol x L(-1).

CONCLUSIONThe method is simple, rapid, sensitive and applicable to the assay of diluted human serum albumin samples.

OBJECTIVEIBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes.

METHODSTotally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed.

RESULTSAfter treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation.

CONCLUSIONSHigh sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

Objective To explore the gene expression of human telomerase reverse transcriptase (hTERT)in childhood acute non- lymphocytic leukemia (ANLL) and its clinical implication. Methods Expression of hTERT mRNA was detected in HL - 60 leukemia cell line, 14 ANLL children and 11 healthy children by reverse transcriptase- polymerase chain reaction (RT- PCR). Results hTERT gene was expressed in HL-60 cell line, ANLL children (11/14) and healthy children (2/11). The expression of hTERT gene was observed in all subtypes of ANLL. Furthermore, there were statistically significant differences in expression levels of hTERT gene between children with ANLL and healthy children (t = 5.034 P = 0). Conclusions The up - regulation of gene expression of hTERT may play a very important role in the progression of children ANLL. The detection of hTERT expression may be a useful additional method for monitoring the state of illness.

OBJECTIVETo study the effect of occupational stress on cardiovascular function of different vocational population.

METHODSThe occupational stressors, risk factors of cardiovascular diseases were investigated by questionnaire in 839 people with 4 kinds of jobs. Blood pressure, sugar, and lipid were detected at the same time.

RESULTSBlood pressure were higher in the groups of old age, long standing and teachers, and the abnormal rate of blood pressure was 21.69%. There was no difference in abnormal ECG among ages, standing and occupation, and the abnormal rate of ECG was 19.07%. Job control, job demands, job responsibility, role in a job and shift work were the main stress factors affecting systolic and diastolic blood pressure. More conflict in job, less chance of participation, severe job loads were the risk factors of primary hypertension. Accident due to job responsibility, job responsibility, role in a job were the main risk factors of abnormal electrocardiograph. Self-respect and activity beyond work were the good modifiers of heart function.
