Pathological changes of Kupffer cells in number and ultrastructure were studied by means of colloidal carbon uptake, endogenous peroxidase cytochemistry, quantitative histology and ultrastructural stereologic morphometry at various time intervals (3,7,14,21,and 28 d) after common bile duct ligation. Kupffer cell phagocytic function and serum fibronectin opsonic activity were measured. The results show the morphological changes of Kupffer cells coinciding with their functional alterations. Alteration of Kupffer cell phagocytic function is mainly due to the changes of number and cellular activity of Kupffer cells.

Objective To study the clinical values of neuron-specific enolase(NSE) as serum tumor marker in lung cancer.Methods The serum NSE levels in 96 patients with lung cancer,60 patients with begnign pulmonary disease and 60 healthy controls were measured by using enzyme-linked immunosorbent assay.Results The levels of NSE in serum in patients with lung cancer was significantly higher than those in healthy subjects and patients with begnign lung disease(P0.05).The effective rate of chemotherapy were 87.10%,40.00% and 66.67%, 33.33% in patients with SCLC and NSCLC,respective for NSE positive and negative ones(P

Objective To discuss the clinical effect of sublingual misoprostol on planned delivery with full-term pregnancy and influence on outcomes of pregnancy and newborns.Methods Ninety-six puerpera with cervical bishop score ≤ 4 were randomly divided into the control group(n =48) and research group (n =48).The patients of the control group were given oxytocin therapy while the research group were given sublingual misoprostol.The promoting effect of cervical maturity,induced abortion effects,outcomes of pregnancy and newborns between the two groups were compared.Results The total effective rate of cervical maturity of research group was obviously higher than that of control group,the differences were statistically significant (91.7％ (44/48) vs 66.7％ (32/48),x2=7.834,P =0.015).The total effective rate of induced abortion effects of research group was obviously higher than that of control group,the differences were statistically significant (93.8％ (45/48) vs 54.2％ (26/48),x2=9.653,P=0.004).The postpartum hemorrhage((183.6±24.2) ml vs.(216.5±32.6) ml,t=6.748),total stageoflabor((7.6±1.3) h vs.(11.3±2.5) h,t=6.636) and cesarean section rate(31.3％ vs.47.9％,x2 =5.637) of research group was obviously lower than that of control group,the differences were statistically significant (P＜0.05).Two groups of newborns and the incidence of neonatal asphyxia,amniotic fluid pollution had no statistically significant difference(P＞0.05).Conclusion The clinical effect of sublingual misoprostol on.planned delivery with full-term pregnancy is obvious and causes little influence on outcomes of pregnancy and newborns.It is safe and effective to be applied on planned delivery and worth popularization and application.

Objective To study the treatment of postoperative pancreatic fistula. Methods The study (retrospectively) reviewed the management of 20 patients with pancreatic fistula. Fifteen patients were treated (conservatively), and 5 patients were treated surgically. Results All of the patients treated conservatively or by (surgery) were cured,and the results were satisfactory. Conclusions The majority of pancreatic fistulas can be cured with conservative management. If the fistula communicates with the main pancreatic duct or fails to heal after 5 months of conservative therapy, operation is necessary.Pancreatic fistulojejunostomy is a simple, safe and effective method.

Epidemiological studies have shown that the incidence of patent foramen ovale (PFO) in patients with cryptogenic stroke is significantly higher than general population.The close association between cryptogenic stroke and PFO supports the hypothesis that paradoxical embolism is a cause of stroke.However,the detection of PFO alone does not establish the diagnosis of paradoxical embolism in patients with cryptogenic stroke. The risk of ischemic stroke will increase significantly when PFO and other factors coexist.Some studies tave shown that there is significant difference between the MRI lesion patterns in patients with cryptogenic stroke and PFO in those without cryptogenic stroke,particularly in multiple ischemic lesions.Therefore,it does not support the theory of paradoxical embolism as a cause of stroke in patients with PFO.The PFO detection methods include transthoracic echocardiography,transesophageal echocardiography (TEE) and transcranial Doppler (TCD).TCD and TEE have a good consistency.Accordingly,TCD should be recommended as a simple,noninvasive,and reliable technique,while TEE should be only restricted to the selected patients.The treatment options of PFO include antiplatelet drugs,anticoagulant drugs,percutaneous vascular closure,and thoracotomy.Percutaneous vascular closure should only be considered the recurrent events during the medical treatment,the contraindications of medical treatment,and PFO with some anatomical high risks for patients with cryptogenic stroke with PFO before the completion of several large randomized controlled trials.
