Objective To study CD64 expression in neutrophilic granulocyte and its clinical effect in neonatal infection disease. Methods CD64 was detected among 59 neonatal patients(septicemia group 34 patients, local infection group 25 patients)hospitalized in our neonatal department diagnosed as neonatal infection disease in 48 h after hospitalized,2 weeks after therapy, then the results were compared with 27 patients as non - infection disease during the same period. Results CD64 in septicemia group was (6156. 21?3643. 32) molecula per cell,in local infection group was (2176.19 ? 946. 32)molecula per cell, in non- infection group was (2176. 19 ? 946. 32) molecula per cell.There were significant differences among three groups (all P0.05). Conclusions CD64 expression increases in bacterium infection disease. It is more obvious in widespread infection desease.and it can be the mark in early diagnosis of neonatal infection disease.

AIMTo investigate factors affecting the properties of antisense oligodeoxy nucleotides (ASON)-liposomes complex and their cellular uptake.

METHODSThree types of blank liposomes were prepared by reverse-phase evaporation vesicles, and the complex were obtained through physical absorption. The light microscope was used to observe morphology characteristics of the complex. Drug loading capacity was analyzed by agarose gel electrophoresis. The transfected cell percentage and means fluorescence intensity were determined by flow cytometric analysis using M3 myeloma cell as a model.

RESULTSThe neutral liposome showed no aggregation while the cationic liposomes appeared some different extent aggregation in different medium when associated antisense oligodeoxynucleotides. The drug loading capacity depended on the ratio of +/- and the cationic charge density on the lipid membrane. The two kinds of cationic liposomes appeared different principles of loading ASON. As far as cellular uptake, The neutral liposomes showed no improvement of cellular uptake of ASON. However, the cationic liposomes were shown to enhance the cellular uptake of ASON if the appropriate +/- charge ratio was used. The optimal cellular uptake was achieved when +/- charge ratio was at 0.5:1 and 1:1 for SA-I liposome and SA-II liposomes, respectively.

CONCLUSIONThe cationic liposomes improved the loading capacity and cell uptake of antisense oligodeoxynucleotides, which was determined by +/- charge ratio and charge density.

OBJECTIVETo investigate the protective effect of melatonin on residual hair follicle cells of scald rats at early stage.

METHODSEighteen male Sprague-Dawley rats were randomly divided into scald group, treatment group, sham group , with 6 rats in each group. The rats in scald group and treatment group were subjected to 30% TBSA partial thickness scald on the back, and were resuscitated with balanced solution after 1 hour, while those in sham group were immersed in water at 37 degrees C for 25 s to simulate scald, and did not receive fluid replacement. Rats in treatment group were intraperitoneally injected with 10 mg/kg melatonin solution at 1 minute, 8 hours and 12 hours after scald, while those in sham group and scald group were given equal volume of 1% alcohol sodium-isotonic saline instead. Tissue samples were harvested at 6, 12 and 24 post scald hours (PSH) for determination of MDA and GSH levels. Apoptosis of residul hair follicle was detected by TUNEL method and immunohistochemistry of caspase-3.

RESULTSThe level of MDA in scald group at each time point was much higher than that in sham group (P < 0.01) and treatment group (P < 0.05), and it peaked at 12 PSH. The changes in GSH were just opposite to that of MDA. Under fluorescence microscope, the residual hair follicle cells were blue, and the apoptotic cells appeared green. The apoptosis rate in scald group at 6, 12, 24 PSH was obviously higher than that in sham (P < 0.01) and treatment groups (P < 0.05), which was (20.2 +/- 3.4)% vs (4.3 +/- 2.3)% vs (10.9 +/- 3.2)%, (31.2 +/- 3.6)% vs (5.1 +/- 2.5)% vs (19.1 +/- 3.7)%, (22.4 +/- 2.7)% vs (4.1 +/- 2.4)% vs (13.1 +/- 3.4)%, respectively. The score of caspase-3 positive cell in scald group was higher than those in sham group (P < 0.01) and treatment group (P < 0.05).

CONCLUSIONSThere is obvious correlation between oxidative stress and apoptosis rate of hair follicle cells in rats with partial thickness scald. Early administration of melatonin may have anti-apoptosis ability for residual hair follicle cells by attenuation of oxidative stress.

AIM: To explore the nursing cooperation highlights of eight osteopetrosis patients underwent optic nerve decompression via transsphenoidal microsurgical approach instead of routine pathway, and to improve the quality of nursing cooperation. ·METHODS: We enrolled 8 cases ( left eye in 3 cases, right eye in 5 cases ) of osteopetrosis patients referred from the Eye Hospital of Wenzhou Medical University during February 2012 to November 2016. Patients received ophthalmic examinations including visual acuity and diagnostic imaging tests in pre-operation and post -operation. All eyes were performed surgical optic nerve decompression through endoscopic approach in assist of image guidance system. We retrospectively analyzed the clinical data and surgical cooperation procedure of these cases and summarized nursing cooperation experience. ·RESULTS:The operations of 8 patients were completed successfully without massive hemorrhage. Mean visual acuity improved from pre-operation (2. 5±2. 1) to post-operation (3. 4±1. 9). Cerebrospinal fluid leakage occurred in 1 patient and was instantly repaired during the operation. We performed the nursing strategy as postural drainage, condition monitoring and conscious assessment intra-and post-operation. ·CONCLUSION: It is the critical for this kind of surgery that both circulating nurse's high-skilled cooperation to the connection and operation of the navigation system, to treat with complication during the surgery, and scrub nurse's sufficient preparation of surgical instruments and consumables, proficient equipment delivery, meticulous management, use and maintenance of equipment.

Objective To investigate the fluctuation of the iodine deficiency disorders(IDD) through continuous monitoring on it. Methods During 2005-2008, 10 monitoring countis (city,district) of IDD were selected in Jiangxi Province. Five townships were selected in each monitoring county, one school was selected in each townships, and 40 students in 8-10 years old from each school were selected to inspect their thyroid glands and determined the idodine content of salts from their home. Among the 40 students, 20 of which were selected to determine the intelligence quotient(IQ) and 6 of which were selected to determine urine iodine. Thirty pregnant women were also selected to determine the urine iodine in each monitoring county. Twenty students of 5th grade in each school and 5 housewives living nearby the school were selected to carry out the questionnaire survey of health education about IDD. Results Monitoring results showed the average goiter rote of 8-10 years old students was between 2.00% and 4.60% during 2005-2008. The rate of IQ of the students higher than 90 was all above 76% each year. The median of urine iodine of students and pregnant women was higher than 100 μg/L, and the proportion of people whose urine iodine content was lower than 50 μg/L was below 4% each year. The rate of inhabitant taking qualified idodine salt wasn't lower than 95%. The pass rate of the questionnaire survey of health education about IDD was between 11.67% and 43.50% in students and 92.50%-99.60% in housewives. Conclusions The situation of iodine deficiency in Jiangxi Province has been greatly improved, reaching the standard of eliminating IDD.

Racemic (±)-F18 (10-chloromethyl-11-demethyl-12-oxo-calanolide A), an analog of nature product (+)-calanolide A, is a new anti-HIV-1 nonnucleoside reverse transcript inhibitor (NNRTI). A successful enantioseparation of (±)-F18 offering (R)-F18 and (S)-F18 was achieved by a chiral stationary phase prepared HPLC. Their absolute configurations were determined by measurement of their electronic circular dichroisms combined with modem quantum-chemical calculations. Further investigation revealed that (R)-F18 and (S)-F18 shared a similar anti-HIV activities, however, (R)-F18 was more potent than (S)-F18 against wild-type virus, K101E mutation and P225H mutation pseudoviruses.
