Through analysis of the general health status and resource allocation and utilization of health services needs of the state,the relationship between the two is discriminated,which suggests that we should strike a balance between the allocation of health resources and the health needs of the residents,to achieve the optimal allocation and utilization,to better serve the cause of development and the promotion of the health of the entire society,and improve health services and economic efficiency.

Objective:To study the optimum extraction conditions for Yaotong granules. Methods:An orthogonal test was adopted to optimize the percolation extraction process of total alkaloids by orthogonal experiment with the yield of dry extract and total extraction rate of tetrandrine and fangchinoline as the indices. Results:The optimal extraction conditions were as follows:the medicinal materials were soaked with crude powder in 60% ethanol for 48h,then percolated at the rate of 2 ml·min-1 ·kg-1 . Conclusion:The extraction technology for Yaotong granules is simple and rapid with stable results,which can provide theoretical basis for the production of Yaotong granules.

Objective To assess the diagnostic value of spiral CT colonography(SCTC)with orally administered Mannitol as negative contrast in colorectal tumor.Methods 27 volunteers and 68 patients suspected of various kinds of colorectal diseases were examined.About 1500 ml isosmotic Mannitol as oral negative contrast agent was administered and then 20mg of Raceanisodamine hydrochloride was injected intramuscularly,three phase enhanced spiral CT scanning was performed 5 to 10 minutes later.imaging data were post-processed with multiplanar reformation(MPR),maximum intensity projection(MIP).All normal colorectal were correctly subarea and were measured intestinal wall thickness and maximum outer diameters,the CT values of bowel wall in different phases were measured either,the bowel with tumor as control,and the results were statistically calculated.SCTC was classifield into three Grades according to the effect of intestinal preparation.CT data of 61 cases colorectal tumors identified by pathology were retrospective analysed.Results SCTC was successfully done in all objects,the SCTC grading included Grade 1 in 52 cases,Grade 2 in 39 cases and Grade 3 in 4 cases.The total rate of satisfaction towards examinantion was 95.8%.The lesions in 60/61 cases were demonstrated clearly by SCTC,among them,there were carcinoma in 30,lyphoma in 8,abscess in 8,polyps in 8,metastases in 4 and carcinoid in 3.One case with polyp(less than 5 mm)was missed.The sensitivity and specificity of SCTC in diagnosing colorectal lesions were 98.36% and 78.9% respectively.27 cases with colorectal carcinoma were correctly staged in Duke and the accuracy was 90%.Conclusion SCTC is a simple,rapid,noninvasive and effective method for evaluating colorectal tumor.

Objective To investigate the expression and characteristics distribution of ciliary neurotrophic factor (CNTF) and its receptor during the development of retina of healthy Sprague-Dawley(SD)and Royal College of Surgeons (RCS) rats with hereditary retinal degeneration. Methods The expression and distribution of ciliary neurotrophic factor and its receptor were detected by immunohistochemical staining in the retinal paraffin sections of SD and RCS rats from newborn to 12 moths old. Results In the normal retina of SD rats 0-7 days after birth, positive CNTF staining was found in all of the retinal layers and the staining of ganglion cells strengthened and other cells weakened as the age of rats increased; the staining of ganglion cells reached the peak at the 4th week and lasted till the agedness. The same results of the CNTF staining were also found in RCS rats retina. Weak positive staining of CNTFR in all of the retinal layers was seen in the 0-3-day-old SD rats; the ganglion cells were darkly stained and incontinuous positive staining at the site which would develop to be the external segment was found; as the age increased, the positive staining of external segment of photoreceptor enhanced and reached the peak at the 14-28th day after birth. At the 56th day, the staining of ganglion cells in retina of SD rats was strengthened while the staining of external segment weakened till the agedness. The expression of CNTFR in retina of 3-14-day-old RCS rats was the same as which of normal SD rats basically, but the staining of external segment weakened obviously from the 21st day on, and negative staining of external and positive ganglion cells were detected at the 28th day till the agedness. Conclusions Expression of CNTF in normal SD rats and RCS rats with hereditary retinal degeneration is almost the same. The presence of significant difference of expression of CNTFR between normal SD rats retina and RCS rats retina may provide the experimental gist for the CNTF treatment to retinal degeneration.

Objective To evaluate efficacy and therapeutic satisfaction of novel analogue glargine combined with repaglinide in type 2 diabetic patients(T2DM) after switching from the most frequently used twice daily injection of premixed insulin(Humulin 70/30 30% rapid acting and 70% NPH before meals).Methods 18 patients with T2DM whose blood glucose control was poor receiving twice daily premixed insulin had been switched to receive a once daily injection of glargine together with repaglinide and biguanides(metfomin) or TZDS(reglitazone) was continued if it was taken to relieve insulin resistance.After 16 weeks the blood glucose concentrations and HbA1c levels were detected and hypoglycemia was reported.Results At the time of post-16week after the switch,fasting blood glucose access to normal;blood glucose fluctuation relieved and HbA1c levels decreased(from 7.84?0.21 to 6.52?0.13).Symptomatic hypoglycemia decreased.Conclusion These results indicate that insulin glargine combined with repaglinide can be replaced from the twice daily premixed insulin injection regiment for the T2DM even with poor glucose control.

AIM: To observe the changes of serum nitric oxide and the production level of IL-1 in different period of coxsackievirus B 4 (CB 4V)-induced insulin-dependent diabetic mice.METHODS: The insulin-dependent diabetes mellitus (IDDM) animal model induced by CB 4V infection was established. Serum nitric oxide level was estimated by nitrate reductase method after infection 72 h,1 week, 3 weeks,6 weeks,8 weeks, respectively. At the same time, level of IL-1 produced by peritoneal M? was measued.RESULTS: (1) Changes of serum nitric oxide: serum nitric oxide level in control group remained normal level. The serum nitric oxide level in diabetic group increased significantly at 72 h after infection(P0.05). (2) IL-1 activities: IL-1 activities were increased obviously from 72 h to 3 weeks after virus infection, but decreased to normal level after 6 weeks.CONCLUSION: Nitric oxide may be one of the important factors in the development of CB 4V-induced IDDM.

The phenotype frequencies of Gc and Tf in blood and bloodstains from the Hannationality in Bejing was studied using the agarose gel simultaneous electrophresisfollowed by the immunofixation method.Their gene frequencies were calculated.

OBJECTIVE:To establish a method for the determination of 100 pesticide residues in Morus alba. METHODS:LC-MS/MS was conducted on the column of ZORBAX Eclipse plus C18 with mobile phase of acetonitrile (containing 5% water, 0.1% formic acid,5 mmol/L ammonium formate)- water(containing 0.1% formic acid,5 mmol/L ammonium formate)(gradient elution)at a flow rate of 0.4 ml/min,column temperature was 40 ℃,injection volume was 5 μl;MS conditions:ionization source was electrospray ionization with positive ion mode,scanning mode was dynamic MRM,scanning time window was 2 min;atomiz-ing gas was nitrogen,atomizing gas pressure was 40 psi,drying gas flow rate was 5 L/min,capillary voltage was 4 000 V,and ion spray voltage was 500 V. RESULTS:The linear range of 100 pesticide residues was 2.4-150 ng/ml(r>0.990 0),recovery was 69.3%-128.2%,and the determination limit was 0.003-16 μg/kg. CONCLUSIONS:The method is simple,stable and reproduc-ible,and can be used for the determination of pesticide residues in M. alba.
