Objective To compare the effects of desflurane and sevoflurane on somatosensory evoked potentials (SEP) in patients undergoing spine neurosurgery. Methods Thirty patients with ASA grades I-Ⅱand undergoing spinal deformity orthopaedic surgery were selected and divided into two groups: desflurane group and sevoflurane group (n=30) . Bispectral index (BIS),the state of muscle relaxation, SEP and hemodynamics were monitored during operation. By maintaining the BIS in the range of 35-45,the state of muscle relaxation disappeared and hemodynamic became stable. Adjust the concentration of anesthetic step by step from 0 to 0.3, 0.6 and 0.9 maximum alveolar concentrations (MAC), then inhaled different concentrations of drugs. Record the incubation period and amplitude of SEP before inhaling anesthetics (based on the value), in the moment of achieving each inhaled concentration ( T1, T2 and T3) , and the moment that the inhaled anesthetics blows completely (regression value) . The percentages of T1, T2, T3, and the regression value compared with basic value were calculated.Results Compared with the basic value, T1, T2 and T3 of left arm, left leg and right leg in desflurane group, T2 and T3 of right arm in desflurane group, T2 and T3 of left arm, left leg and right arm in sevoflurane group,and T2 and T3 of right leg in sevoflurane group showed incubation period delaying ( <0.05) . And the incubation period extended along with the increase of inhaled anesthetics dosage. Compared with the basic value,T1,T2 and T1 of left arm and left leg in desflurane group,T1 of right arm in desflurane group, T1 and T2 of right leg in desflurane, T3 of left arm in sevoflurane group, T1 and T3 in left leg in sevoflurane group had decreased amplitude ( < 0.05), especially T1. Compared with desflurane, sevoflurane showed a weaker inhibition effect on the incubation period and amplitude of T1,T2,T3 of left arm and left leg,T2 and T3 of right arm and right leg, and the amplitude of T1 of right leg ( < 0.05) . Conclusion Both of desflurane and sevoflurane have inhibition effect on SEP. The inhibition effect gradually strengthens along with the increasing of dose. The inhibition effect of desflurane is stronger than sevoflurane.

OBJECTIVETo explore the efficacy of Tuina for postpartum lactation and work out a optimal protocol involved.

METHODSWith a randomized, controlled and clinical method, 84 primiparas were divided into a Tuina group and a control group. While patients in the control group received rooming-in conventional managements, those in the Tuina group were additionally treated with Tuina, including local manipulations on breasts combined with acupoint manipulations. The colostrum-time, lactation quantity and prolactin were observed to make the comparisons between two groups.

RESULTSThe scores of lactation quantity after 1th, 2nd, 3rd of the treatment were 1.660 +/- 0.785, 2.530 +/- 1.030, 2.880 +/- 1.171 in Tuina group and 1.270 +/- 0.533, 1.460 +/- 0.811, 1.500 +/- 0.583 in control group respectively, where there were significant differences in each time stage between two groups (all P < 0.001). The time of colostrum was (21.6 6 +/- 10.508) h in the Tuina group and (22.5 +/- 9.762) h in the control group, in which the difference was not statistically significant (P > 0.05). The levels of prolactin (314.35 +/- 110.37) ng/mL and (321.56 +/- 109.61) ng/mL in Tuina group, (385.78 +/- 85.19) ng/mL and (340.12 +/- 103.10) ng/mL in control group before and after treatment, there were no significant differences (both P > 0.05).

CONCLUSIONPostpartum Tuina on breasts could increase the quantity of lactation and delay the decreasing of the levels of prolactin, which contributes primiparas to lactate more and sooner.

Ultrasonic microbubbles were used to open blood-brain barriers (BBB) with a reversed and limited behavior feature in the study, which could improve the brain-targeted delivery of anti-tumor drugs. The glioma rat model was prepared. Low-frequency ultrasound was combined with microbubbles to affect the permeability of BBB compared with the permeability of independently administered Evans blue (EB) crossing BBB. Time point and length of ultrasound were investigated whether they affect the permeability of BBB and the damage of brain tissue. The effect of the growth time of glioma on BBB permeability was explored. Only glioma had a very little impact on BBB permeability. However, ultrasonic microbubbles opened the BBB with the features of temporary, limited and reversed behavior and improved EB and magnetic resonance imaging contrast agent penetrating BBB. A length of 30 s ultrasound is appropriate for opening BBB and no damage of brain tissue. Drugs should be injected before ultrasound so that they enter into brain as BBB opening. Ultrasonic microbubbles can open BBB effectively and safely, which improve drugs penetrating BBB under proper time point and length.

Objective To evaluate the role of early cleavage embryo in combination with embryo growth rate and morphology scoring in embryo selection in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods Six hundred and ten IVF/ICSI cycles were randomly assigned to group A(269 cycles) and group B(341 cycles). In group A, transferred embryos were chosen according to embryo growth rate and morphology scoring by 72 h(D3) after fertilization, while early cleavage embryo was added to the selecting system in group B. The pregnancy rate and implantation rate were compared between two groups, and the clinic outcomes were compared between transfers with early cleavage embryos and without early cleavage embryos in group B. Results The pregnancy rate and implantation rate in group B were significantly higher than those in group A (P < 0.05). Transfers with early cleavage embryos also achieved much higher pregnancy rate and implantation rate in group B (P < 0.01). Conclusion Compared with embryo growth rate and morphology scoring, early cleavage embryo in combination with embryo growth rate and morphology scoring can improve the clinical outcomes in IVF/ICSI cycles.

Mean platelet volume (MPV) is an early marker of platelet activation.Larger platelets,compared to small ones,increase platelet adhesion and aggregation,and present a higher thrombotic activity.Some studies have explored the association between MPV and the morbidity of portal vein thrombosis (PVT).The aim of this study was to evaluate the predictive effect of MPV in patients with PVT by a meta-analysis.We searched Pubmed,Web of Science,SCOPUS,OVID,CNKI and CBMD from database inception to September 13,2017.Seven studies in accordance with selection criteria were included.The extraction of basic data was independently conducted by two reviewers.The mean difference in MPV between PVT patients and controls were pooled with weighted mean difference (WMD)and 95％ confidence interval of 0.88 fl (95％ CI:0.61-1.15).A random-effect model was chosen for an obvious heterogeneity in the pooling (Chi-square=27.12,df=6,P＜0.0001,I2=77.9％).The sources of heterogeneity were from the difference of primary disease of participants and portal vein diameter.Taken together,our results reveal that MPV is a predictive indicator in patients with PVT.

Objective:To observe the effect of acupoint massage plus acupoint sticking therapy for the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery.Methods:A total of 120 patients undergoing nasal endoscopic surgery were included,and all patients were under trachea intubation and general anesthesia.The patients were randomized into an observation group and a control group,with 60 patients in each group.Patients in the control group received conventional anesthesia resuscitation,while patients in the observation group received acupoint massage plus acupoint sticking therapy on the basis of conventional anesthesia resuscitation.Changes in the heart rate (HR),systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed at three time points including the end of the surgery (TO),the removal of the tracheal tube (T1) and 10 min after the removal of the tracheal tube (T2).The awakening and tube removal time,choking cough and restlessness,and adverse reactions (dizziness,nausea and vomiting) in 24 h post-surgery period were compared.Results:At T1 and T2,the comparisons of HR,SBP and DBP between the two groups showed statistical significance (all P＜0.05).Intra-group comparisons showed that the HR,SBP and DBP of the control group at T1 and T2 were significant different from those at TO (all P＜0.05).There were significant differences in the awakening time and tube removal time between the two groups (both P＜0.05).The incidences of choking cough and restlessness were 8.3％ and 3.3％ respectively in the observation group,versus 53.3％ and 30.0％ in the control group,and the between-group comparisons showed statistical significance (both P＜0.05).The incidences of dizziness,nausea and vomiting in 24 h post-surgery period were 3.3％,5.0％ and 0.0％ respectively in the observation group,versus 43.3％,33.3％ and 25.0％ in the control group,and the between-group comparisons showed statistical significance (all P＜0.05).Conclusion:Acupoint massage plus acupoint sticking therapy can effectively regulate the stress reaction during postoperative anesthesia recovery period in patients undergoing nasal endoscopic surgery,and maintain a stable internal environment.

Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.

Objective To explore the expression of osteopontin (OPN) in mucosal epithelium of oral local lesion in patients with oral lichen planus(OLP). Methods Forty patients with pathologically-confirmed OLP (erosive OLP,n=15; reticular OLP,n=25) were investigated,among whom 17 were complicated with mild dysplasia. Mucosal epithelium of oral local lesion was examined for the expression of OPN by immunohistochemical method. Forty healthy subjects were served as normal controls. Results The positive expression rates of OPN were 65.4% and 82.4%,respectively in patients with OLP and those complicated with mild dysplasia,and both were significantly higher than that in normal controls (10.0%) (P0.05),while both were significantly higher than that in normal controls (P
