Objective To discuss the non-antibiotic Chinese medicine therapy for the non-gonococcus conjunctivitis in newborns, and reduce the use of antibiotic and the production of bear-medicine-bacterium. Methods 0.9%-sodium chloride was used as the inoculation fluid, Shuanghuanglian (freezing and drying) was uscd as dissolution injection. Dexamethasone sodium phosphate injection 1ml: 5mg was added, mixed-fluid 16ml was matched to spray the eyes after ultrasonic-atomization equipment atomizes. Results 56 examples 103 eyes which had the nongonococcus conjunctivitis in newborns were treated only with the injection with the Shuanghuanglian dexamethasone sodium phosphate injection mixed with the fluided ultrasonic-atomization equipment atomizes and the total effectiveness reached 97.08%. Conclusion The Shuanghuanglian-ultrasonic-atomization way to treat non-gonococcal conjunctivitis in the newborns is safe and effective.

Objective To assess antibiotic prescription habits,cost pattern and the prospective intervention in Intensive Care Unit was analyzed.Methods Data on antibiotic utilization and antibiotics susceptibility were col-lected prospectively from individual electronic charts from July 2014 to September 2014.Results 225 of 246 patients surveyed used antimicrobial during the ICU stay,and antibacterial drug utilization rate was 91.46%.Cefperazone-sulbactam and piperacillin-tazobactam were the most prescribed medications.Total defined daily dose ( DDDs) was 1121.1 DDDs.Bacteria culture was 98 positive in 677 cases and 101 pathogenic bacteria were isolated.Conclusion Interventional programs should focus on promoting infectious control with rational antibiotic prescription aimed at mini-mizing the future emergence of bacterial resistance and futile.

Objective To discuss the role of naso-carbon in the protection of parathyroid during surgery. Methods 72 patients were randomly divided into the two groups,Injecting 0.1-0.2mL nano-carbon in the thyroid during a thyroid surgery.When the thyroid and surrounding lymph tissue were stained,then the thyroid surgery should be continued,the non-stained tissue should be protected.Results There were 6 cases with hypocalcemia in the con-trol group and 2 cases in the observation group(χ2 =13.87,P<0.05).5 cases with PTH decrease in the control group and 1 case in the observation group(χ2 =14.53,P<0.05).7 parathyroid glands were examined in the control group,while none in the observation group(χ2 =127.54,P<0.05).Conclusion Using naso-carbon during the thy-roid surgery,parathyroid gland cannot be stained black.The parathyroid gland can be easily identified and preserved.

Background Reliable intraocular pressure (IOP) measurement is essential in glaucomatous study.TonoLab is a newly designed tonometer for small animals,however,its repeatability and reproducibility remains unknown.Objective This study aimed to evaluate the repeatability and reproducibility of TonoLab rebound tonometer in DBA/2J mice.Methods Intraocular pressure was measured in both eyes of 63 DBA/2J mice aged 7 months under systemic anesthesia with TonoLab rebound tonometer.IOP of each eye was measured for 3 times by two observers independently and consecutively using TonoLab rebound tonometer,and the data were obtained in single blind method.Within standard deviation (Sw),interclass correlation coefficient (ICC),within coefficient of variation (CVw) and corresponding 95％ confidence interval (CI) were calculated to evaluate the repeatability of measuring result from single observer,and Bland-Altman method was used to assess the agreement between two observers.The abnormal data which affected repeatability was analyzed.Results Among the 126 eyes,105 eyes showed the normal IOP with mean value (12.98 ± 1.05) mmHg from observer 1 and (12.41 ±0.92) mmHg from observer 2.Ocular hypertension was found in 21 eyes with mean value (27.76 ± 1.95) mmHg and (27.49 ± 1.28) mmHg for observer 1 and observer 2 respectively.Sw,ICC and CVw for observer 1/observer 2 were 1.34/1.11 mmHg,0.90/0.92,8.24％/7.42％ in normal eyes and 2.21/1.49 mmHg,0.89/0.95,6.97％/4.82％ in hypertensive eyes.The average bias between two measuring values from different observers was 0.60 mmHg in the normal eyes (95％ CI:-5.20-6.30 mmHg) and 0.30 mmHg in the hypertensive eyes (95％ CI:-7.30-7.80 mmHg).Conclusions TonoLab rebound tonometer can offer a good intraobserver repeatability in both normal and hypertensive eyes in mice,but the agreement between two observers is outside an acceptable level.So we consider IOP in mice obtained by TonoLab rebound tonometer is reliable and accurate from a single observer.
