Background Clinical research showed that the corneal endothelial cell density value from different corneal specula microscopies exist diversity.The relevant literature of SP02,Tomey EM-3000 and SP3000P is still seldom up to now. Objective This research was to assess the repeatability of endothelial cell density measurements by SP02,Tomey EM-3000 and SP3000P respectively and the agreement among 3 kinds of endothelial microscopes.MethodsFifty-four healthy volunteers with the age 17-38 years old were included this research.The written informed consent was obtained from each subject before examination.The corneal endothelial cell densities in the right eyes were analyzed with SP02,Tomey EM-3000 and SP3000P respectively for 3 times under the automatic mode,and the analytical procedure of SP3000P measurement were divided into automatic mode SP3000P (A) and manual correction modes SP3000P( M).The repeatability of each specula microscopy was analyzed by calculating the intraclass correlation coefficients (ICC) and coefficient of variation ( CV ),and the 95％ confidence intervals and plotting Bland-Altman graphs were used to analyze the agreement among these methods.ResultsThe mean corneal endothelial cell densities in the population ＜24 years were significantly higher than the ones ≥ 24 years (t =3.692,P＜0.05 ),but no statistical difference was found between different gender ( t =0.335,P =0.739 ).The mean corneal endothelial cell densities were ( 3058 ± 260 ),( 2954 ± 229 ),( 2668 ± 258 ),( 2734 ± 268 ) cell/mm2 ; the ICCs were 0.957,0.940,0.972 and 0.972 and the CV were 0.063,0.061,0.056,0.058 for SP02,Tomey EM-3000,SP3000P (A) and SP3000P ( M ) respectively.The 95％ confidence intervals were ( - 100.8 - 306.8 ),( 162.6 - 617.4 ),( 109.9-494.1 ) and ( -0.6 - 132.6 ) cell/mm2 for between SP02 and Tomey EM-3000,SP3000P ( A ) and SP02,SP3000P(A) and Tomey EM-3000,SP3000P(A) and SP 3000P(M) respectively.ConclusionsSP02,Tomey EM-3000 and SP3000P(A) have good repeatability in the measurement of corneal endothelial cell density,however the outcome is different.Therefore,it is not interchangeable for the detection of corneal endothelial cell density.The differences of corneal endothelial cell density obtained from these instruments shall be paid high attention for their differences.SP3000P(A) and SP3000P(M) can be used interehangeably and SP3000P(A) is a preferable choice due to its convenience and quickness.

Objective To cxplore the variation of the range of motion (ROM) of operative level after different heights of artificial cervical disc replacement,and to provide guidance for clinical work in selecting appropriate height of artificial cervical disc prosthesis.Methods The preoperative cervical anteroposterior and lateral Ⅹ-rays of 9 fresh male cadaveric cervical spine specimens were obtained to measure the intervertebral height of C5-6,and 3 screened specimens with the height of about 5 mm were included in the experiment.The experiment was designed to test self-control,and other four groups of cervical specimens including intact group,appropriate height (5 mm) of C5.6 artificial cervical disc replacement group,1mm increased (6 mm) group and 2 mm increased (7 mm) group were made biomechanical test sequentially.The specimens were fixed to the cervical three-dimensional movement machine,with a 75 N follower load and pure moments of 2 Nm for flexion/extension 、left/right bending and left/right axial rotation,to measure the ROM of operative level under the condition of changes in 0.2 Nm/s.Results There were no significant differences in the ROM of flexion/extension,lateral bending and axial rotation between 5 mm group and intact group;the ROM of flexion/extension、lateral bending and axial rotation in 6 mm group increased compared with 5 mm group,but the difference was not statistically significant;the ROM of flexion/extension in 7 mm group was significantly less than that of intact,5mm and 6 mm group (9.5°± 1.0° vs 12.5°±0.9°、11.3°±0.8°、11.6°±0.9°),but significantly greater in axial rotation than 6 mm group (10.4°±1.4°vs 8.6°±0.3°),and there was no significant difference in lateral bending compared with other 3 groups.Conclusion 2 adjacent heights of cervical disc prostheses are implantedsuitably when testing the mold of disc prosthesis,the choice of cervical disc prosthesis with 1 mm increased can improve the ROM of operative level to some extent;while the height with 2 mm increased can lead to the ROM of flexion/extension at the operative level reduced,but the ROM of rotation shows an increasing trend.

OBJECTIVETo investigate the effect of intralipid on protein consumption in severe burned patients. METHODS; Sixty-seven nonoperative patients with severe burns were divided into Intralipid treatment group and non-intralipid treatment group (control group), and the former was treated with 20% intralipid (500 ml once a day) from postburn day 4 for 10 consecutive days. Venous blood samples were collected from these patients for testing total protein, albumin, total cholesterol and triglyceride on postburn days 1, 7 and 14, respectively.

RESULTSThe levels of total protein, albumin, total cholesterol and triglyceride were within normal range on postburn day 1 in both groups, and only the albumin level was lowered in the groups on day 7 but at comparable magnitudes (32+/-4.83 vs 31+/-5.04 g/L, P<0.05). In contrast, the levels of total protein, albumin, total cholesterol and triglyceride were below the normal range on postburn day 14 in both groups, but intralipid treatment group showed more albumin loss than the control group (28+/-6.46 vs 23+/-7.03 g/L, P<0.01).

CONCLUSIONIntralipid (20%) provides good energy source to ameliorate albumin loss in severe burned patients.

OBJECTIVETo determine the adequate timing of antibiotics application in severely burned patients by observing the dynamic changes of amikacin in blister fluid during early postburn stage.

METHODSTwenty patients in early stage of sever burns were divided into 4 groups (n=5) according to the timing of amikacin administration, namely at 3-4 h (group A), 10 h (group B, 20 h (group C), and 30 h (group D) postburn. Amikacin was administered intravenously via a single dose of 400 mg within 30 min, and at the time points of 0.25 to 7 h after completion of the infusion, the blister fluid was collected from each patient for determination of amikacin concentration with fluorescence polarization immunoassay.

RESULTSFifteen minutes after intravenous administration, amikacin could be detected in the blister fluid, reaching the highest level at 1-2 h after administration followed by gradual declination. In group B, blister fluid amikacin concentration reached 4.96+1.60 microg/ml 15 min after administration, and at the subsequent time points until 4 h, amikacin concentration was significantly higher in groups A and B than in groups C and D (P<0.05). Amikacin concentration in the blister fluid in group D was not sufficient for effective antibacterial therapy.

CONCLUSIONAmikacin administration in the early postburn stage may ensure higher amikacin concentration in the blister fluid and wound exudate. Better antibacterial effect can be expected when amikacin is applied within the initial 10 h postburn.

OBJECTIVETo investigate the concentration and pharmacokinetics changes of amikacin in the serum and blister fluid in severe burn patients at early stage.

METHODSTwenty severe burn patients during early postburn stage were divided into four groups with five patients in each group. Each patient was given a single dose of 400 mg amikacin in 30 minutes during 3-4 postburn hour (PBH) in A group, at 10 PBH in B group, at 20 PBH in C group, and at 30 PBH in D group. The concentration of amikacin in blister fluid was examined at 0.25, 0.5 min and 1, 2, 3, 4, 5, 6, 7 h after treatment by fluorescence polarization immunoassay, meanwhile, the venous blood of 9 patients among them was also collected to determine the concentration of amikacin at the same time points. Pharmacokinetics parameters of model were produced by program 3P97.

RESULTSAmong all groups, the concentration of amikacin in blister fluid in A group increased quickest and maintained longest, that of B group ranked second. The amikacin concentration of blister fluid in A, B groups were obviously higher than those in C, D groups at each time point (P <0.05 orP < 0.01), especially at 1PBH (12.53 +/- 1.76, 9.52 +/- 1.51 microg/mL vs 4.65 +/- 0.77, 3.10 +/- 0.41 microg/ml, P < 0.01). The serum concentration of amikacin in 9 patients were decreasing along with elapse of time. The amikacin concentration-time curves in blister fluid and serum were best fit in two compartment models. Compared with that in normal value, t1/2beta of amikacin from burn patient was shortened in serum and prolonged in blister fluid.

CONCLUSIONEarly administration of amikacin in burn patients (within 10 PBH) may form an effective and continuous antibiotics barrier around the wound to prevent bacterial infection.

OBJECTIVETo investigate the changes in pharmacokinetic parameters of vancomycin in the subeschar tissue fluid (STF) at early post-burn stage in patients with severe burns.

METHODSTen patients with severe burns were enrolled in the study and received intravenous injection of 500 mg vancomycin at an even rate within 60 mins 1 to 2 hours after admission. A total of 0.5 ml STF was collected each time and the concentration of vancomycin in the STF was determined by fluorescence polarization immunoassay (FPIA) method at 1, 2, 4, 8, 24, 48, 96, 144, 192, 240 post-burn hours (PBH). Pharmacokinetic parameters of vancomycin were produced by program 3P97 and statistically analyzed by program package SPSS10. 0.

RESULTSThe STF concentration-time curves of vancomycin were best fit in two compartment model. Pharmacokinetic parameters of vancomycin in the STF were: t1/2alpha = (3.7 +/- 2.6) h, t1/2beta = (92 +/- 12)h, Vc = (26 +/- 6)L, AUC = (1279 +/- 256) microg x h x ml(-1), CLs = (0.40 +/- 0.08) L/h.

CONCLUSIONWhen vancomycin is used early after severe burns, the drug can be retained in the third space, and the concentration of the drug can be maintained for over 24hrs, and it is beneficial to form an antibiotic barrier around the wound to prevent an invasive bacterial infection to the burn wound.
