In order to promote the farmers' health and to relieve their financial burden, a scientific program of appropriate health technology application in countryside has been performed from "10th five-year" to "11th five-year " period in Henan Province. Some practical experiences have been accumulated. Based on these experiences, the mechanism construction of the long-term application was discussed in this article.

Objective To compare the clinical efficacy of two different injection ways in treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol. Methods During the period from Dec. 2010 to Dec. 2012 a total of 80 patients with clinically-proved lower extremity varicosis were admitted to authors’ hospital. The patients were randomly and equally divided into two groups:anterograde group (n=40) and retrograde group (n=40). For patients of anterograde group, under fluoroscopy guidance the needle was directly punctured into the distal end of the varicose vein with subsequent injection of 1%lauromacrogol foam sclerosing agent, while for patients of retrograde group the opposite femoral vein was punctured by using Seldinger technique, then a catheter was inserted into the proximal part of the great saphenous vein of the diseased side, and 1%lauromacrogol foam sclerosing agent was injected into the varicose vein. The operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment were recorded, and the results were statistically analyzed. All the patients were followed up for 3 - 6 months. Results No significant difference in the overall effective rate existed between the two groups at 3-6 months after the treatment (P>0.05). The preoperative and postoperative CEAP scores of the anterograde group were 3.70 ± 0.63 and 0.88 ± 1.18 respectively, while the preoperative and postoperative CEAP scores of the retrograde group were 3.73 ± 0.59 and 0.88 ± 1.27 respectively. The difference in CEAP score between preoperative values and postoperative ones was statistically significant in both anterograde group and retrograde group (P < 0.05). Besides, the differences in the operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment between the two groups were also statistically significant. Conclusion In treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol, the overall effectiveness of anterograde injection and retrograde injection is quite the same. As each injection way has its own advantages and disadvantages, the therapeutic scheme should be individualized for each patient.

The cholinesterase(ChE)and lactate dehydrogenase(LDH)activities in blood smears of 37 patients were observed before and 20 minutes after electroacupuncture.Hegu and Zusanli were mainly chosen as the acupuncture points.Karnovsky method was used to demonstrate ChE,activity,and tetrazolium-formazan reaction for LDH activity. Before acupuncture,all formed elements of blood showed both ChE and LDH acti- vities.In red blood cells ChE and LDH activities were localized at the cell membrane, while in white blood cells they were found throughout the cytoplasm as colored granu- les.The granulocytes showed greater ChE and lesser LDH activities than the lymph- ocytes.The platelets also showed greater LDH and ChE activities,especially the former. On the whole,platelets and leucocytes,as compared with erythrocytes,showed greater activities for ChE and LDH. Under microscopic observation,according to the amount and color of granules,the degrees of GhE and LDH activities for each kind of blood formed elements before and after acupuncture were recorded as different markes,such as +、++、+++ and so on.The degrees of GhE or LDH activity in various formed elements of blood were compared by means of statistical tests.After acupuncture,both GhE and LDH activities of all blood formed elements were increased(p

70 patients including 60 cases under acupuncture anesthesia and 10 cases under drug anesthesia were observed. Before and 20 minutes after acupuncture the blood samples were taken from the patient ear lobes respectively, and in some patients taken once again 24 hrs after acupuncture. The electroacupuncture point Hegu or Zusanli was mainly adopted. As the method for detection of cell-mediated immunity(CMI) in vitro the improved microtechnique of whole blood for E-rosette (active and nonactive) and lymphocyte transformation tests was used. In performance of active rosetting the total leucocyte count and the differential lymphocyte count were done for calculation of absolute number of active rosette forming cells (RFC). The mean value of increase of active RFC was 12.7?1.43, the decrease was 6.8?1.77 after acupuncture. The increment of the absolute number of active RFC was 175?63.59. However no marked effect on the drug anesthesia group was found. In the lymphocyte transformation assay the increase was 12.7?1.49, the decrease was 7.0?2.19, and the enhancement effect still exhibited 24 hrs after acupuncture. In these tests an increase was mostly found in those with a lower or a usual CMI level; a decrease often found in those with a higher CMI level prior to acupuncture. The increase or decrease level in the results of three kinds of test (active, nonactive RFC and lymphocyte transformation) was similar, the increase range was 12～13%, the decrease range 6～7%. As the former compared with the latter, the promotion was prominent by all means.

AIM To observe the clinical role for Supplemented Xijiao Powder (Bubali cornu,Coptidis Rhizoma,Cimicifugae Rhizoma,etc.) in management of hepatitis B virus (HBV) associated acute-on-chronic liver failure.METHOD Seventy-five patients,including the ones receiving internal medicine treatment,were divided into control group and experimental group.The experimental group received conventional treatment and additionally took Supplemented Xijiao Powder for one month.The clinical symptoms and signs were observed.Levels of ALT,AST,TBIL,ALB,CHE,PTA were measured,and the incidence of liver failure was evaluated.RESULTS Supplemented Xijiao Powder could improve symptoms,signs and the level of PTA.The incidence of liver failure tended to reduce.The comparison of other indexes had no marked difference.CONCLUSION Supplemented Xijiao Powder has a certain therapeutic effect on HBV associated prioracute-on-chronic liver failure.Its mechanism may be related to blocking the occurrence of liver failure.
