1.Early diagnosis and rapid treatments of gastrointestinal fistula.
Chinese Journal of Gastrointestinal Surgery 2006;9(4):279-280
Traditional treatments of gastrointestinal fistula include early drainage, maintaining nutrition and then resection of fistula at the proper time,which usually take three to four months or even longer. Rapid treatments of gastrointestinal fistula mean promoting rapid spontaneous closure of tract fistula and early primary resection of fistula within two weeks after fistula occurrence. Early diagnosis is the premise of early management, and fistulography and abdominal CT scan are important early diagnostic methods. Most of fistula could close spontaneously in the maintaining stage. To promote the rapid closure, however, special measures including sufficient drainage, somatostatin and total parenteral nutrition in the early stage should be implemented to avoid intra-abdominal collection of intestinal fluid and infection, control further leakage of intestinal fluid and improve nutritional status. In the late stage,when leakage of intestinal fluid could be controlled, recombine human growth hormone (rhGH) and enteral nutrition should be administered in place of somatostatin and total parenteral nutrition respectively. The fistula can reach rapid spontaneous closure in both stages. Fibrin glue and rhGH used at the same time can improve the curative rate and shorten the treatment time even more. In the 1960s and 1970s, early primary resection of the fistula and re-anastomosis often resulted in anastomosis failure. The reasons for this included poor nutritional status, uncontrolled secretion of intestinal fluid, severe intra-abdominal infection and multiorgan dysfunction syndrome. Such stage management policy has been proposed, developed and persisted since late 1960s. Nowadays, the advance of medical science provided the possibility to change or improve the current policy. Our research proved that early resection of the primary fistula and re-anastomosis of the small bowel could be performed successfully in some selected patients whose general conditions are good and intestinal adhesion were not severe within ten to fourteen days after fistula occurrence. More studies are still needed to define the indications and contradictions for early resection of the primary gastrointestinal fistula, and prove the feasibility and rationality of rapid treatments of gastrointestinal fistula.

A combination vaccine which consists of ≥2 immunogens is intended to provide protection against two or more diseases or against multiple serotypes of a single disease. The use of combination vaccines decrease the number of vaccine injections in the regular immunization schedules. However,the development of combination vaccines is more complicated than monovalent vaccines,preservatives and adjuvants used with one component may alter the potency of other components. Physical,chemical,and biological interactions between the components of combination vaccines must be considered to avoid detrimental effects on safety or efficacy. Therefore combination vaccines present unique challenges for product evaluation. This paper presents a review of research application status,the evaluation of effectiveness and safety,as well as development prospects on combination vaccines.

Objective To explore the possibility of early definitive operation for enteric fistulas. Methods In 37 selected enterocutaneous fistula patients, early definitive operation was performed during laparotomy for treating peritonitis within 10 days of fistula formation. Thorough irrigation of peritoneal cavity, effective sump drainage, fibrin glue sealant to reinforce anastomosis, appropriate nutritional support, and administration of growth hormone were key elements of perioperative management. Results Among 37 patients, 35 of them recovered uneventfully. Fistula recurred in 2 cases postoperatively; one fistula closed after conservative management, and another patient died of advanced gastric cancer 3 months postoperatively. The fistula operative closure rate was 94.5%. No operative death. Conclusion Advances in perioperative management can promote the success rate of early definitive operation for enteric fistulas. It may become a challenge to the present strategy of enteric fistula management.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.
METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.
RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).
CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

OBJECTIVETo establish the "clinical-mimetic" Chinese medicine symptom complex score method for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome, in order to observe the effect of formula of removing both phlegm and blood stasis (TYTZ) on the Chinese medicine symptom complex score for the coronary heart disease Chinese miniature swine model with phlegm-stasis cementation syndrome.
METHODTotally 36 Chinese miniature swine were randomly divided to the normal control group, the model group, the Shujiangzhi group, and TYTZ groups with doses of 2.0, 1.0 and 0.5 g x kg(-1), with six in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. After the operation, the groups were administered with drugs for eight weeks. Their main symptoms, accompanied symptoms, tongue and pulse signs of the coronary heart disease Chinese miniature swine with phlengm-stasis cementation syndrome were observed according to the symptom-graded scoring method.
RESULTCompared with the model group, TYTZ in different doses could reduce the scores of main symptoms at the 6th and 10th week. Specifically, TYTZ in low dose could reduce the scores of tongue at the 6th week and the scores of accompanied symptoms, and tongue and pulse signs at the 10th week; And TYTZ in high dose could decrease all symptom scores at the 6th and 10th week (P < 0.05 or P < 0.01).
CONCLUSIONTYTZ can improve the scores of the main symptoms, accompanied symptoms, tongue and pulse signs in coronary heart disease Chinese miniature swine with phlegm-stasis cementation syndrome. It is suggested that the "clinical-mimetic" objective scoring for syndromes of Chinese miniature swine is of great significant to the development of new traditional Chinese medicine drugs.
