Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.

Myeloid differentiation factor MyD88 is a critical adaptor molecule that integrates and transduces intracellular signals in inducing the differentiation of dendritic cells (DCs).The domain regions within MyD88 was searched,it could potentially affect the function of dendritic cells and found that MyD88 aa155-171 motif not only regulate the activity of transcription factor NF-?B, but also control the production of cytokines and expression of costimulatory molecules. Indeed, aa155-171 motif deleted type MyD88 (MyD88155-171) transfected RAW264.7 cells exhibited the reduced NF-?B and AP-1 activity and interrupted the expression of CD86 and B7H1. Meanwhile, lower level expression of cytokines such as IL-12,IFN-? were also observed by means of cytokine array in MyD88-/-DC trasfected with MyD88155-171 as compared to the MyD88 transfected cells. Thus, aa155-171 motif inside MyD88 could affect the expression of costimulatory molecules, production of cytokines and transduction of Toll like receptor signal pathway, suggesting that this motif may play an important role in regulating responses of innate immune system.

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

BACKGROUNDTo date, there have been no reports on altered nitric oxide (NO) content in ischemia/reperfusion with regard to in vivo preconditioning procedures. These studies are important for understanding the mechanisms of NO during early myocardial ischemic preconditioning. The aim of the present study was to investigate the mechanisms of NO during early myocardial ischemic preconditioning by measuring levels of NO and cyclic guanosine monophosphate (cGMP), as well as activity of nitric oxide synthase (NOS) in ischemia/reperfusion with respect to preconditioning in rats.

METHODSSixty-six female Sprague-Dawley rats were randomly divided into four groups: ischemic preconditioning group (IP), ischemia/reperfusion group (I/R), control group (CON), and preconditioning procedure group (PC). In the PC group, rats were further divided into PC1-, PC1 +, PC2-, PC2 +, PC3-, and PC3 + subgroups. Rats underwent left coronary artery occlusion and reperfusion, and subsequently, NOS activity and levels were assessed with spectrophotometric analysis. cGMP contents were measured with radioimmunoassay.

RESULTSThe level of NO and cGMP, as well as the activity of NOS, were significantly higher in the IP group compared to the I/R and CON groups (P < 0.05). During preconditioning prior to prolonged ischemia, NO and cGMP levels varied markedly with ischemia and reperfusion. The levels of NO repeatedly increased when the heart was exposed to three episodes of 5-minute ischemia, and were almost completely reversed during each reperfusion period. NO and cGMP levels were significantly different between the 5-minute period of ischemia and the same period of reperfusion during preconditioning.

CONCLUSIONSNO plays an important role during early phase myocardial ischemic preconditioning in rats. NO and cGMP could be triggers and mediators of early phase myocardial ischemic preconditioning. Altered NOS activity following ischemic stress could be the primary inducer of higher NO levels detected. NO and cGMP fluctuations might be the trigger for protection during early phase myocardial ischemic preconditioning.
