1.Recognition and Interaction of Innate Immune Receptors
Progress in Biochemistry and Biophysics 2006;0(02):-
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.

Objective This study assessed whether the best overall response rate(ORR) of cetuximab combined with oxaliplatin,leucovorin and fluorouracil/Xeloda was superior to that of this method alone as first-line treatment for metastatic colorectal cancer.The influence of KRAS mutation status was investigated.Methods Patients received cetuximab(400mg/m2 initial dose followed by 250mg/m2,wk thereafter)less than 2 times plus chemotherapy(oxaliplatin 130mg/m2 on day 1,plus leucovorin 200mg/m2 and fluorouracil as a 400mg/m2 bolus followed by a 600mg/m2 infusion during 22 hours on days 1 and 2) or chemotherapy alone.Treatment was continued until disease progression or unacceptable toxicity.KRAS mutation status was assessed in the subset of patients with assessable tumor samples.Results The confirmed ORR for cetuximab plus oxaliplatin,leucovorin and fluorouracil/Xeloda was higher than that with alone(42.86% vs 21.74%).A statistically significant increase in the odds for a response with the addition of cetuximab to oxaliplatin,leucovorin and fluorouracil/Xeloda could be established.In patients with KRAS wild-type tumors,the addition of cetuximab to oxaliplatin,leucovorin and fluorouracil/Xeloda was associated with a clinically significant increased chance of response(ORR 54.55% vs 21.74%) and a lower risk as compared with chemothrapy alone.Cetuximab plus oxaliplatin,leucovorin and fluorouracil/Xeloda was generally well tolerated.Conclusion The clinical effcacy of chemothrapy(oxaliplatin,leucovorin and fluorouracil/Xeloda) plus cetuximab is better than only chemothrapy.KRAS mutational status was shown to be a highly predictive selection criterion in the treatment decision regarding the addition of cetuximab to oxaliplatin,leucovorin and fluorouracil/Xeloda for previously untreated patients with metastatic colorectal cancer.

OBJECTIVE To survey the knowledge about the prevention by hepatitis B vaccination among vaccine recipients and inquiry persons,and formulate the measure of health education on prevention of HBV. METHODS 349 cases of hepatitis vaccines and inquiry persons in infirmary from Oct 2006 to Feb 2008 were selected,and making questionaire investigation for the understanding of HBV infection. RESULTS The initiative consciousness of prevention to HBV was manily focused on young people. The 20 to 40 years old people were 81%,3% below 20 years and 16% over 40 years among the investegatees. The correct rate of cognition was 36.4%. CONCLUSIONS To propagandize the knowledge about HBV and make the people to understanding the HVB,and increase the consciousness for prevention. To reduce the mistake cognition for HBV infection and encourage the high-risk people to receive the hepatitis vaccination.

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.

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 observe the impact of hyperbaric oxygen (HBO) therapy on blood pressure and heart rate in adults with spinal cord injury (SCI). Methods 48 adult SCI patients who accepted HBO therapy from March to November, 2014, were observed. Other 48 non-SCI patients matched sexes and ages were as the controls. Their blood pressure and heart rate were measured before chambering, before compression, HBO for 30 minutes, before decompression and at the end of decompression. The patients were divided into high SCI group and low SCI group based on the injury levels above or below T4. Results The blood pressure was lower in the high SCI patients than their controls (t>6.337, P<0.001), and increased as taking in the oxygen. There was no significant difference between the high SCI patients than their controls as they took in for 30 minutes and before the decompression (P>0.05). No difference was found between both groups in heart rate (P>0.05). For the low SCI patients, neither the blood pressure nor the heart rate was different from their controls (P>0.05). Conclusion The blood pressure may increase during HBO intaking in the high SCI patients, which need be paid attention to.
