The oculocardiac reflex (OCR) occurs in up to 90% of ophthalmological surgeries,while most of the clinicians consider the performance of OCR is just bradycardia and arrhythmia and therefore ignore other system manifestation such as oculorespiratory reflex( ORR) and oculo-emetic reflex(OER),and so on.OCR appears not only in ophthalmological surgeries,and it also occurs during the endoscopic sinus surgery.A unstable bradycardia associated with stimulation of the mandibular division of cranial nerve V during trigeminal neuralgia pain treatment is also reported.This phenomenon is mostly introduced only as clinical manifestations.Therefore,it is helpful for us to understand the essential characteristic of OCR.The embryonic,anatomy,physiology and electrophysiology were reviewed in this article and thought to term it as oculovagal reflex is more comprehensive.

Objective To understand the relationship between coagulation function and birth weight and gestational age in newborn. Methods Five hundred premature infants in NICU from June 2015 to June 2016 were enrolled. Perinatal high-risk factors(gestational hypertension, gestational diabetes, placenta previa, spontaneous premature delivery) and general status (gestational age, sex, delivery mode, birth weight)were documented. Blood coagulation function (PT, APTT, FDP, DD, FIB, AT-Ⅲ) was detected within 6 h after birth. The premature infants were divided into three groups according to gestational age, early preterm neonate group (28-30+6 weeks, 48 cases), moderate preterm neonate group (31-33+6 weeks, 125 cases), and late preterm neonate group (34-36+6 weeks, 216 cases). And there were 111 term infants (37- 42 weeks, 111 cases). In addition , the relation between birth weight and coagulation function was analyzed. Sixty-six twins were collected and divided into tow groups according to their weight, the-lighter group and the-heavier group. The coagulation function was analyzed and compared among different gestational age groups. Results There were no differences in perinatal risk factors (P > 0.05). There were significant differences in various coagulation parameters among three groups [APTT: (93.25 ± 21.34), (82.80 ± 21.37), (78.29 ± 17.77), (62.03 ± 13.7) s;FIB: (1.95 ± 0.96), (1.67 ± 0.60), (1.51 ± 2.44), (1.40 ± 0.85) g/L; DD: (2.11 ± 0.64), (1.02 ± 0.33), (0.66 ± 0.31), (0.51 ± 0.25) mg/L;AT-Ⅲ:(25.89 ± 11.80)%, (33.86 ± 11.40)%, (36.65 ± 13.60)%, (45.18 ± 14.82)%] (P<0.05). The levels of APTT, FDP, DD tended to decrease with the increasing of gestational age. The level of FIB and AT-Ⅲtended to increase with the increasing of gestational age. Correlation analysis showed that the levels of APTT, FDP, and DD were negatively correlated with gestational age (P<0.05) and the levels of FIB and AT-Ⅲwere positively correlated with gestational age (P<0.05). In the twins group, no significant difference was showed in different weight (P > 0.05). Conclusions The coagulation function in early life in premature infants is associated with gestational age, and has no relationship with birth weight. The coagulation function of premature infants is in a changing and gradually mature process, which should be monitored dynamically.

Mechanical ventilation plays an important role in the treatment of preterm infants,especially respiratory problems.With improvement in both antenatal and neonatal care and therapeutic strategies,premature babies are surviving more than ever.However,the incidence of bronchpulmonary dysplasia remains high which affects the clihical outcomes of premature infants.Non-invasive respiratory support techniques have been used in attempts to decrease lung injury and the complications of preterm infants.This review will focus on various ventilation modalities for managing preterm infants with respiratory failure and lung protective ventilation strategies to minimize lung injury in preterm infants.

In view of China's medical equipment industry has not been equipped with a sound system and strict administration, it is wise to draw on FDA recommendations and seek effective ways of solving EMI problems. Further should focus on improving the performance of medical equipment so as to adapt to the different environment. In the end, the design of healthcare facilities to meet EMC standards is put forward specifically in four parts of electronic circuits, power circuits, display device, and the mechanical shell.

Dipeptidyl peptidase-Ⅳ (DPP-Ⅳ/CD26,EC 3.4.14.5),a transmembrane serine polypeptidase,is widely distributed and has diverse effects.As a dipeptidase,DPP-Ⅳ/CD26 could not only regulate the activity of many peptide hormones,neuropeptides,cytokines and growth factors via its peptidase function,but also mediate cell-matrix and cell-cell contact through interactions with other molecules or proteins as a surface antigen.DPP-Ⅳ/CD26 plays a regulatory role in immune activation,inflammation and tumorigenesis.This review covers the structure,distribution,physiological functions and changes in pathological state of Dpp-Ⅳ/CD26.

Maxillary sinusitis is a common condition in nose section. Traditional operations are always have more complications and easy to relapse, seriously affectting the quality of patient's life. The application of functional endoscopic sinus surgery (FESS) makes a qualitative progress on surgical treatment of maxillary sinusitis. In re- cent years, the researchs found that there are still unsatisfactories to long-term curative effect of some patients With the development of minimally invasive, people begin doubting its "functional". Recently, some new treat- merits have emerged in the world, but their safety and effectiveness needs further research. To seek for a better treatment, this article reviews the development and the existential problems of maxillary sinusitis surgery.

Objective:To investigate the thoughts and the methods of clinical pharmacists in the individual continuous renal re-placement therapy ( CRRT) anticoagulation treatment for severe patients. Methods:Clinical pharmacists participated in the CRRT anti-coagulation treatment for one patient with severe thrombocytopenia after aortic dissection surgery. Clinical pharmacists analyzed the cau-ses of thrombocytopenia and the coagulation function of the patient to exclude heparin-induced thrombocytopenia, and developed the treatment of supplementing platelets and regional citrate anticoagulation as the way of CRRT. Results:Three days after the treatment, the patient was changed to the general ward with normal renal function. Conclusion:Clinical pharmacists should participate in clinical treatment comprehensively and perform individual treatment for patients in order to ensure the effect and safety of medication.
