OBJECTIVE To explore the causes, predilection sites and treatment of nasal sinus mucoceles after hypophysectomy.METHODS The clinical data of 7 cases with nasal sinus mucoceles after hypophysectomy diagnosed and treated in our Department from Jan.1998 to Aug.2007 were retrospectively studied.RESULTS The mucoceles were located at ethmoid sinus in 2 cases,frontal sinus in 2 cases,frontal and ethmoid sinuses in 3 cases.All of the 7 cases underwent mucocelectomy under nasal endoscope or a combined endoscopic intranasal and extra-nasal approach.No recurrence was found after follow up for 1 to 3 years.CONCLUSION The causes of nasal sinus mucoceles after hypophysectomy are the change of the anatomic structure of nasal cavity after surgery.The stenosis,adhesion of middle nasal meatus or obstruction of the sinus ostium are found in all the patients.Intranasal endoscopic surgery or combined with extra-nasal approach is the first choice for nasal sinus mucoceles.

The demands for Traditional Chinese Medicine(TCM)standardization are rising internationally,but the development for TCM intemational standards is confronted with competence.In this context,the authors analyzed the competing status of intemationalized TCM standardization from 3 aspects:1.It is the key point for competition that obtaining leadership in the international organization and dominant position in developing important intemational standards:2.Integrating technical development and intellectual property with intemational standards has been gradually formed;3.Striving to make breakthrough in the development of TCM international standards on the basis of TCM Chinese national standards.The authors recommend that international standards be initiated from TCM service standards.TCM products quality standards and TCM process standards.

Noninfectious diarrhea is a kind of digestive disease caused by many factors and the main clinical features are increased frequency of defecation and change of character of stool,most of the patients have intestinal microecological imbalance. Improving the intestinal microecological balance is very important in the treatment of noninfectious diarrhea. Microbial ecological agent(MEA)has definite efficacy for the treatment of noninfectious diarrhea,and gradually becomes the commonly used drug for noninfectious diarrhea in clinical practice. This article reviewed the use of MEA in the treatment of noninfectious diarrhea.

The status of bioelectrical impedance measurement especially the multifrequency segmental bioelectrical impedance measurement of liver diseases is introduced.The multifrequency segmental bioelectrical impedance can well rule out the impact from the change of body weight caused by edema and ascites,and can evaluate the volume of ascites.Compared with single frequency bioelectrical impedance,the multi frequency bioelectrical impedance measurements probably display good prospect.It helps to produce objective judgement on nutrition status and energy metabolism for patients with liver diseases.The effect,however,needs further clinical research.

The rate of malnutrition occurrence in patients of hepatocirrhosis is high,and the most of them is the protein-energy malnutrition.Nutrition support is important in the therapy.The following aspects are introduced in the article,including the causation of malnutrition of hepatocirrhosis,appropriate rate of nitrogen and energy,nutritional route and the doctor′s recognition of malnutrition in patients of cirrhosis.

Objective To discuss the causes and management of the complications of the transurethral electrovaporization of prostate(TVP) to improve the effect.Methods All 820 cases took TVP.3～6 months follow-up was taken to investigate the complications and their disposal.Results No patient died,6 cases had massive haemorrhage during operation,6 cases had presymptom of TUR syndrome,5 cases had perforation of juncture of bladder and prostate,6 cases had acute pulmonary thromboembolism(PTE) after TVP,32 cases had spasm of bladder,18 cases had urethral stricture,3 caess had postoperative bleed,11 cases had retrograde ejaculation,13 cases had temporary incontinence,24 cases had infection of urinary tract.Conclusion Pre-operational precautions are essential,the complications of TVP may be decreased by accurate operation and reliable management of infection.

Lifelong blood cell production is achieved by the capacity of hematopoietic stem cell(HSC) to differentiate and self-renew.A growing body of evidence suggest that DNA damage induced HSC senescence may be the principal mechanism of aging and HSC exhaustion in response to the stress exposure.Understanding the mechanisms of HSC senescence will help to find new therapeutics that can ameliorate HSC injury induced by chemo-and radiotherapy,elucidate the molecular mechanisms whereby leukemia/cancer stem cell arise and evade cancer therapy by escaping senescence,and identify the novel molecular targets for intervention.

Objective To study the mechanism of rat blood pressure lowered by SO2 and SO2 derivatives.Methods 6-Keto-PGF1? and TXB2 were determined by radioimmunoassay in the plasma and aorta tissue of rats.Results The 6-Keto increased significantly in the isolated aortic rings in all exposure groups except 8 mmol/L group.No change of TXB2 was observed in the rings in all exposure groups.Meanwhile,6-Keto/TXB2 ratios increased significantly at 2 mmol/L and 4 mmol/L.Compared with the control group,6-Keto level decreased significantly in the plasma of the rats exposed to SO2 at 14 mg/m3,28mg/m3 and 56 mg/m3,but the level of TXB2 increased significantly.6-Keto/TXB2 ratios decreased gradually with the increase of SO2 concentration.Conclusion PGI2 and TXA2 are possibly changed by SO2 and SO2 derivatives,which regulates partly rat blood pressure.
