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.

The establishment of cerebral collateral circulation is a secondary compensatory mechanism after cerebral ischemia.The expression of endogenous angiogenic growth factors is up regulated,angiogenesis and arteriogenesis are initiated,and the establishment of collateral circulation is accelerated after cerebral ischemia.Some drugs may promote the establishment of collateral circulation after ischemic stroke and improve the prognosis of patients.

Objective:To study the Raman spectrum and the surface enhanced Raman spectrum ( SERS) of cefalexin, cefadroxil and cephradine, and analyze the surface enhanced Raman spectrum of the three compounds under different pH conditions. Methods:The Raman spectrum and the surface enhanced Raman spectrum of the three compounds under different pH conditions were detected and measured by a portable Raman spectroscopy. Results: The results showed that the three compounds could exhibit characteristic peak information in the surface enhanced Raman spectroscopy corresponding to that in the normal Raman spectrum, and the pH values had certain impact on the surface enhanced Raman spectrum of the three substances. Conclusion: Both the Raman spectrum and the surface enhanced Raman spectrum of cefalexin, cefadroxil and cephradine reflect certain fingerprint characteristics, and it is feasible to use Raman scattering method to identify the three cephalosporins.

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.

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 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.

OBJECTIVE:To summarize the method and experience of clinical pharmacist participating in pharmaceutical care for a case of refractory class Ⅳ+Ⅴ lupus nephritis (LN). METHODS:Clinical pharmacists and physicians formulated individualized treatment together,i.e. prednisone 30 mg/d+MMF 0.5 g,q12 h+FK506 1 mg,q12 h;on the fifth day of treatment,the patient suf-fered from ardent fever and increase of blood pressure,and clinical pharmacist suggested using linezolid 0.6 g,ivdrip,q12 h+merope-nem1.0 g,ivdrip,q8 h to control pulmonary infection;using Amlodipine besylate tablet 5 mg,po,qd+one Valsartan hydrochlorothia-zide capsule, po,qd+Arotinolol hydrochlorid tablet 10 mg,po,bid to control blood pressure. RESULTS:Multi-target treatment for re-fractory class Ⅳ+Ⅴ lupus nephritis achieved efficacy:the patient got higher plasma albumin and lower 24 h urine protein quantity af-ter 14 days;the patient suffered from secondary pulmonary infection and high blood pressure;physicians adopted the pharmacist’s suggestion so that pulmonary infection and blood pressure had been controlled. CONCLUSIONS:To ensure the effectiveness and safe-ty of the multi-target treatment,clinical pharmacists should formulate individualized treatment,focus on the possible ADR and provide phamaceutical care in the field of blood pressure monitoring,infection control,etc. when participating in multi-target treatment.

Objective: To explore the Influence of ethics education on ethical beliefs of dual relationship of trainees who attend training of psychological consultation.Methods: Use of questionnaire,written and directed by "psychological counseling and treatment of ethical issues questionnaire(trainee attending psychological consultation training)" as a tool to evaluate,within the framework of Guangdong 368 trainees to investigate.Results: Compared with two groups of trainees,in refer to the ethical beliefs of dual relationship,the latter group who has a higher option of "not sure" shows varying degrees of decline in most of the items in the questionnaire.Two teams of trainees reach an identity of 80% or more(10 items in total) in the ethical judgment of dual relationship(choose "not").Two groups show significant differences in judging 5 items of the entries(p
