NKR and TLR are most important receptor superfamilies in innate immunity and act as first line of host defense against infection. Those receptors exert peculiar recognition mechanisms to sense danger signals and distinguish infectious nonself from noninfectious self. More importantly, they coordinate and regulate each other and therefore play major roles in initiation of innate immunity and also help to direct adaptive immune responses. The importance of recognition and interaction of those receptors are highlighted. The precise mechanisms can be harnessed to aid the rational design of therapy against infection, inflammation, cancer or autoimmune diseases.

The development of the nerves of the small intestine was studied in 26 human fetuses with the gestational age of 11 to 40 weeks.The findings are as follows:(1)The distance between the Auerbach's ganglia and the muscular layer is small in the early fetal period and it increases progressively as the fetus grows.(2)The density of neuropils increases gradually.(3)The number of large gradual vacuoles (LGV) is small in the 3rd month of gestation,and it increases gradually and is quite numerous in the 6th month.(4)The morphology of the synapses is not so typical as that of an adult.(5)The peak values of the stereological morphological parameters of the organelles in the neurons appear between the 4th-6th month and maintain at a relatively high level until the baby is bron.

To treat residual or recurrent stones after operation on hepatolithiasis conveniently and effectively, a subcutaneous permanent tunnel to bile duct (SPTBD) was established in 564 cases of hepatolithiasis by using an afferent jejunum or a well-functioned gallbladder in order to provide a postoperative way to remove residual or recurrent stones through cholangioscopy. We found that by cutting SPTBD open to remove residual or recurrent stones through cholangioscopy in 96 out of 238 followed-up cases, all the patients got good clinical effects without death or complications. The results suggest that it is a good method to establish a SPTBD during operation in patient with hepatolithiasis. It is a simple and effective way to cut SPTBD open to remove residual or recurrent stones after operation.

Objective To explore the clinical significance of injecting the tumescent fluid into the separated space in breast augmentation by transaxillary incision under gerenal anesthesia. Methods In 203 cases of breast augmentations by transaxillary incision, some tumescent fluid was injected into the incision and submuscular or subgland space, and then separated under general anethesia. By comparison of the 210 cases without tumescent fluid, the advantages and the clinical significances of this approach were discussed. Results There were less bleeding, early allevation of pain after operation and decreased incidence of local congestion and swelling in patients with tumescent fluid. Conclusion The tumescent fluid could reduce bleeding, early pain after operation and local congestion and swelling in the breast augmentation under general anesthesia.

Objective To find out the possession and utilization of urban medical resources in Henan as well as other factors like medical quality, service level and human resources. Methods A general investigation was made of the possession and structure of health resources and the level of medical services in second tier urban hospitals and above in 18 cities of Henan Province. Results There are altogether 182 second tier urban hospitals in the province, with a total of 51 107 beds and a total of 22 859 doctors. The ratio of doctors to nurses is 1∶1 04, the bed utilization rate is 65 55%, the bed workdays are 234 63 days, the average bed turnover frequency is 15 51 times, and the average length of stay is 13 87 days. The average income surplus per hospital is 1 502 700 yuan, with the income from the sale of pharmaceuticals accounting for 44 67% of the total income. Conclusion The operating efficiency of second tier urban hospitals and above in Henan Province is close to the average national level, the structure of hospital allocations needs readjustment, and the percentage of income from the sale of pharmaceuticals is on the high side.

Objective To explore the effects of oxidative stress and pulmonary vascular permeability on lung injury in rats treated with sodium cyanide(NaCN) and /or hypobaric hypoxia.Methods A total of 72 male SD rats were randomly divided into 2 groups: the NaCN intoxicated group in 308m altitude and the hypobaric hypoxia combined NaCN intoxicated group in 4 000m high altitude.The animals for the experiment of hypoxia were processed in an artificial hypobaric chamber to simulate the designated high altitude hypoxia(4 000m,61kPa).NaCN was injected subcutaneously to the rats in the both groups at the dosage of 3.6mg/kg.Broncho-alveolar lavage fluid(BALF) and lung tissues were prepared at the time points of 0,0.5,1.0,2.0,4.0 and 6.0h.The activity of SOD,GSH-PX,ACE,LDH,AKP and the content of MDA,GSH,Evan's blue(EB) were detected by spectrophotometric method.Results Combined acute hypobaric hypoxia and NaCN intoxication produced a significant increasing effect on EB content in the rats.The activity of ACE,LDH and AKP in BALF,and the contents of MDA in BALF and lung tissue reached the highest value at 0.5h preparation at the combined hypobaric hypoxia and NaCN intoxicated group,but they were still higher than that of control group(NaCN intoxicated only);correspondingly the activity of SOD,GSH-PX,content of GSH in lung tissue and BALF reached the lowest value at 0.5h preparation at the combined hypobaric hypoxia and NaCN intoxicated group,but they were still lower than that of control NaCN intoxicated group.Conclusion The results suggest that under the condition of hypoxia,NaCN intoxication may produce severe harmful effects on the lungs,increase the pulmonary vascular permeability,and cause severe interference on to the oxidative stress level.
