As an important landmark, the posterolateral wall of maxillary sinus can help to locate numbers of significant signs such as maxillary artery and its branches, maxillary nerve and infraorbital nerve, infratemporal fossa and pterygopalatine fossa etc. in the endoscopic surgery for paranasal sinuses and lateral skull base. This article reviewed related researches about the anatomy and endoscopic surgery of posterolateral wall of maxillary sinus.

Objective To study the diagnosis and treatment of abdominal aortic anurysm-intestinal fistula(AAA-IF). Methods The diagnosis and treatment of one patient with AAA-IF was reported, while a literateres review of AAA-IF was made. Results A 50 years old femal patient abmitted due to upper abdominal pain for two month, and an AAA was found in the explore laparotomy. The patient suddenly occurred severe upper abdominal pain accompanied with shock and massive upper gastrointestinal bleeding 13 days after the operation. The preoperative suspected diagnosis was AAA-IF. An AAA-IF was ound during emergent operation. AAA-IF resection with artifial vessel replacement, resection of the forth portion of duodenal and upper portion of jejunal were performed together. The patient recovered eventurely except high body temperature. After vigovous antibiotics therapy, the patient recovered. Conclusions AAA-IF is a rare disordor, the mortality can be as high as over 30%. The key points of redecing mortality are that the diagnosis and treatment should be in time; postoperative vigorous antibiotics should be given, because the AAA-IF patient tends to occur septic complications due to the communication occurred between the AAA and intestinal tract.

Pigment epithelium-derived factor (PEDF), a member of the serine protease inhibitor (serpin) family, is well known for its endogenous antiangiogenic activity. The down-regulation or depletion of PEDF has been shown in many tumor tissues, and it was proved to be correlated with the prognosis of tumor. At present,the biological properties of PEDF and the mechanism of its anti-tumor activity have become a focus research, and it provides theoretical foundation to the treatment of carcinoma.

Objective To investigate the microcosmic pathologic mechanism of ac upoint application for asthma. Methods Sixty guinea pigs were randomly alloca ted to three groups: Group A (model control), Group B (guinea pig model treated with acupoint application) and Group C (normal control). Group B was treated wit h the application of herbal medicines on the acupoints located at neck and back. Results From the 6th day of treatment, incubation period of nodding breath was prolonged in Group B as compared with Group A (P

Leucocoprinus birnbaumill (Corda)Sing.is a new recorded species in Sichuan province,which belongs to Basidiomycota.It is a poisonous and view and admire mushroom.Hyphae of Leucocoprinus birnbaumii (Corda) Sing.have not clamp connection,but can form sclerotium.This is a rare event of Agaricales.The morphological characteristics,physiological characteristics of mycelium and fruit\|body,and the aftificial cultivate technology of this mushroom are report in this paper.It is a typical medium\|hightemperature mushroom.Grass powder,cow dung,wheat bran and cultivated spent compost of edible fungi etc,conventional combination are cultural fruiting substratum;with bottle,bag,beds cultivation are all feasible,the biological efficiency of dry mushroom is about 5%～7 5%.

Objective To investigate the effects of low molecular weight heparin (LMWH) on severe acute pancreatitis(SAP). Methods Retrospective analysis was made on the clinical features and therapeutic effect on the routine treatment (RT) group in 48 cases and LMWH treatment(LT) group in 31 cases. Results 28 (90.3%) out of 31 cases were cured while 3 (9.7%) died in LT group. 35(72.9%) out of 48 cases were cured whereas 15 (27.1%) died in RT group. The complications occurring in LT group (32.3%,10 patients 18 times ) was significantly lower than that in the RT group (62.5%,30 patients 59 times)(P

Objective To study the relationship between expression of Caspase 3 and regression of hemangioma. Methods Caspase 3 expression was detected in 79 hemangiomas and 5 normal skin tissues by immunohistochemistry (SP). Results In 79 hemangiomas, the positive rates of Caspase 3 expression in proliferating, involuting and involuted phases were 52.4%, 91.2% and 83.3%, respectively. The expression of Caspase 3 in involuted and involuting phases was higher than proliferating phase( P 0.05). Conclusion Caspase 3 is involved in the converting of hemangiomas from proliferating phase into involuting phase. The activation of Caspase 3 may induce apoptosis of endothelial cells, thus leading to the regression of hemagioma.

The materal-neonatal safety and materal stress response were evaluated during intratheeal anesthesia. Method: Forty-two parturients(ASA grade 1 )were randomly divided into two groups: spinal group (n=21), epidural group (n=21). 3 ml of 0.5% hyperbaric bupivacaine was given in spinal group; 12-15ml of 0.75 % bupivacaine was administrated in epidural group. Materal arterial samples were drawn before anesthesia,after anesthesia induction, after delivery and at the end of surgery; umbilieal venous samples were taken for measurements of blood catecholamine, sugar and lactate concentrations. Result; Compared with those before intrathecal blockade, plasma levels of catecholamine of two groups were significantly decreased in different periods during anesthesia (P0.05); there were not any significant differences between the two groups in neonate Apgar scores. Conclusion:Both of two techniques can inhibit stress response of parturients to cesarean sections and have no adverse effects to neonates when applied in proper management.

209 cases of allergic asthma were randomly divided into two groups, which received respectively traditional medicinal vesiculation and drug application based on syndrome differentiation, and their short - term and long - term therapeutic effects were investigated and compared, and the relation between the clinical therapeutic effects of the two application therapies and classification of TCM syndrome differentiation was further analysed. Results show that the total effective rate of the short -term of drug application based on syndrome differentiation is higher than that of medicinal vesiculation, and the clinical thertapeutic effect is closely related to classification of syndrome differentiation, the therapeutic effect of the short -term is the highest for lung -heat type and the worst for Yang-deficiency of kidney.
