ObjectiveTo investigate the clinical effect of nape acupuncture on post-stroke dysphagia by a meta-analysis.Method Domestic literature on clinical randomized controlled trials of nape acupuncture treatment of post-stroke dysphagia published from Jun. 2004 to Jun. 2014 were obtained by a computer search ofChina National Knowledge Internet(CNKI), Wanfang Data medical information system (WF), VIP information resource system (VIP) and Chinese Biomedical Literature Database (CBM) combined with a manual search of Jinan University library journal database. Literature inclusion and exclusion criteria were established to extract data and the qualities of the included studies were assessed using a Jadad rating scale. A meta-analysis was made using the software ReviewManager 5.2.ResultA total of 17 articles were included with 1158 patients. The results of meta-analysis showed that there were statistically significant differences in the total efficacy rate [OR=3.99, 95%CI(2.83, 5.63),P<0.00001] and the cure rate[OR=2.67, 95%CI(2.03, 3.53),P<0.00001] between the nape acupuncture and control groups.ConclusionNape acupuncture has clinically a good therapeutic effect on post-stroke dysphagia. Multi-center, large-sample and high-quality studies are still needed for validation because the qualities of the included articles are lower, which is one of the factors influencing the assessment.

Established a multidisciplinary team, according to theoretical framework basing on the evidence of continuous quality improvement model, combining with evidence and clinical practice to develop evidence-based solutions, the comparison of international normalized ratio (INR) before and after the intervention in the percentage of time in therapeutic range (TTR) and anticoagulant related the incidence of complications.Results:Before and after the multidisciplinary evidence-based intervention, the mean TTR of the patients were (51.67±31.04)% and (64.34±26.37)%, with statistically significant differences ( tvalue was 6.958, P<0.01); the incidence of bleeding and embolization was not statistically significant ( χ 2values were 0.294 and 0.268, P>0.05). Conclusion:Nursing-led multidisciplinary evidence-based interventions can improve the intensity and stability of oral warfarin anticoagulant therapy in inpatients.

OBJECTIVE: To determine an approach enriching cancer stem cells from laryngeal cancer cell line. To investigate whether laryngeal cancer stem cells in chemoradiotherapy have the characteristic of resistance. METHOD: CD133+ cells and CD133- cells was detected and isolated from Hep-2 cell line by fluorescence activated cell sorting technology. The cytotoxicities of cisplatin and radiation were investigated by cell counting kit-8(CCK-8) assay. The apoptosis and cell cycle was analyzed with flow cytometry. RESULT: CD133+ cells accounted for a fraction of (2.43 +/- 0.77)% in Hep-2 cell line. CD133+ cells have a more obvious characteristics of cancer stem cells. Different cisplatin and radiation concentrations of for two cell have inhibition, in a certain concentration range and the dosage dependence. Cisplatin and radiation had synergistic inhibitory effects with CD133- cells on the growth of two cell. Moreover, cell cycle arrest at G0/G1 phase and more apoptosis was induced by synergistic combination. Different concentrations of cetuximab for Hep-2 cells have inhibition, in a certain concentration range and time and the dosage dependence. The half maxial inhibitory concentration (IC50) of cetuximab to Hep-2 cells on 24 h was 1 036.84 microg/L. Cisplatin and radiation had synergistic inhibitory effects with cetuximab on the growth of Hep-2 cell line. Moreover, cell cycle arrest at G0/G1 phase and more apoptosis was induced by synergistic combination. CONCLUSION Compared with CD133- cells, CD133+ cells subpopulation exhibited extraordinary cancer stem.

Objective To investigate the effect of VPA and molecular hydrogen(H2)on phenotypes of microglia treated with hypoxia. Methods Mouse hypoxic BV2 microglia were treated with VPA or H2. The levels of phenotypic markers of supernatant and cells were detected by ELISA, flow cytometry and real?time PCR,respectively. Results Hypoxia significantly increased mRNA level of M1 marker(iNOS)and reduced mRNA levels of M2 markers(CD206 and TGF?β)in BV2(P<0.05). Besides,the ratio between the mRNA levels of M1 increased(P<0.05). VPA significantly reduced protein level(CD16/32)and mRNA production(iNOS)of M1 markers in hypoxia?treated BV2(P<0.05). The ratio be?tween the mRNA levels of M1 markers and M2 markers(CD16:CD206,CD32:CD206,iNOS:CD206 and iNOS:TGF?β)were also significantly decreased(P<0.05). H2 significantly reduced both protein levels(TNF?α,CD16/32 and iNOS)and mRNA production(iNOS)of M1 markers and increased secretion of M2 marker(IL?10)in hypoxia?treated BV2(P<0.05). The ratio between the mRNA levels of M1 markers and M2 markers(CD16:CD206,iNOS:CD206 and iNOS:TGF?β)were also highly declined(P<0.05). Conclusion Hypoxia can induce microglial cells toward pro?inflammatory phenotype. Both VPA and H2 can inhibit hypoxia?induced inflammatory effect on microglia.

Objective To discuss the value of intrapartum operation in management of birth defects and the prognosis. Methods From August 2008 to November 2009, 11 fetuses were identified with birth defects through 3D color Doppler ultrasound and confirmed by MRI and fetal karyotype in the Maternal Fetal Medicine Center, Affiliated Shengjing Hospital, China Medical University including three lymphangiomas,two congenital diaphragmatic hernias (CDH), one sacrococcygeal teratoma, three omphalocele and two gastroschisi. All the above identified birth defects were indications for surgery. All fetuses were born abdominally and received intrapartum operations, including three intrapartum fetal operations with placental infusion (two repairs of CDH, one sacrococcygeal teratoma resection), six ex-utero intrapartum treatment (EXIT; two repairs of omphalocele, two repairs of gastroschisi, two lymphangioma resection) and two surgeries in house (one omphalocele repair and one lymphangioma resection). Both the mothers and fetuses were regularly followed up. Results ( 1 ) Operations: the average operating time for the three intrapartum fetal operations was 89 minites, 5.5 minites for the six EXIT, during which EXIT was performed first,followed by blocking the umbilical circulation and neonatal surgery, and 37 minites for the two surgeries in house. All neonates survived except for one death from severe CDH at 3.5 hours after the operation. The average blood loss for cesarean section and fetal operation was 275 ml. All mothers recovered soon without fever or infection and were discharged three to five days after the operation. (2) Follow-ups: the ten survived neonates were followed up at 1 - 18 mouths at the pediatric clinics and all were growing and developing normally except for one baby with gastroschisi suffered from enteral torsion and feeding intolerance showed lower weight than babies at the same age, but catched up to normal at four months old after posture therapy. One baby with mild CDH developed pulmonary infection at two months after operation with 1/4 pneumothorax on chest X-ray, and were hospitalized for two weeks. At six months old, patent ductus arteriosus was diagnosed in the same baby and chest X-ray was normal. The baby with omphalocele was complicated with ventricular septal defect before operation and the cardiac function was normal during followups for one year. The baby with sacrococcygeal teratoma was reported to have no automatic micturition, but recovered to normal at one month of age. Conclusion Babies with certain birth defects can be managed through intrapartum operation with better outcomes.

Objective:To meet the individualized needs of residents in standardized residency training of cardiac intervention specialty for cardiac ultrasound teaching, to construct a bionic 3D printing model of ultrasound source, and to discuss its application value in ultrasound teaching and simulation exercises.Methods:Sixty residents majored in cardiovascular medicine receiving standardized residency training of ultrasound in ultrasound imaging department of Renmin Hospital of Wuhan University were randomized into experimental group and control group in average. The experimental group adopted ultrasound bionic 3D printing heart model combined with problem-based learning (PBL) teaching method, and the control group adopted traditional multimedia PPT combined with PBL teaching method. At the end of teaching activities, theoretical examination, operation assessment and questionnaire survey were conducted to evaluate and compare the teaching effect between the two groups. SPSS 21.0 software was performed for t test. Results:The theoretical examination scores of the experimental group and the control group were (81.4±8.2) points and (74.8±9.4) points, respectively, P=0.002, and the operation assessment scores were (89.1±5.6) points and (71.5±8.8) points, respectively, P<0.001. The questionnaire survey showed that the experimental group had better feedbacks than the control group in the aspects of mastery of heart anatomy knowledge, learning experience, learning interest, learning efficiency, understanding of interventional heart disease, clinical skills of interventional operation and overall satisfaction (all P<0.05). Conclusions:Ultrasound bionic 3D printing combined with PBL teaching method can help strengthen the mastery of cardiac anatomy knowledge, promote the learning experience of cardiac ultrasound and improve the skills of interventional operation. The teaching effect is significant and the students' satisfaction is high.

Objective To investigate the feasibility,security,indication and prophylactic measures of postpartum hemorrhage during the fetalintrapartum operation by analyze the maternal prognosis after intrapartum fetal operation(IFO) performed.Methods We performed a retrospective evaluation of 10 cases that has been performed intrapartum fetal operation(IFO group,n=10) successfully between August 2008 and October 2009 at Department of Obstetrics and Gynecology,Shengjing Hospital,China Medical University.Healthy pregnant women(n=10) were chosen as control group,who received Caesarean section for refusing to vaginal delivery.Between the two groups,we compared the indexes including blood lose during the operation and 24 hours post-operation,the hemoglobin level pre-operation and 24 hours post-operation,the involution of uterus,the puerperal infection,and the follow-up at 42 days post-operation.Results Good involution,no primary and secondary postpartum hemorrhage and no puerperal infection were found in both of the 2 groups.Intra-operation,24 hours post-operation and the total volumes of blood lose,the hemoglobin level before operation,24 hours post-operation and 42 days post-operation had no statistic significant difference between the IFO group and control group(P>0.05).No significant difference was found in the operation time between IFO group and the control group(66.40±53.40 minutes and 34.50±4.97 minutes,respectively.Intra-operation,24 hours post-operation and the total volume of blood lose had no relation to the maternal age and gestational weeks(P>0.05).The blood lose of intra-operation in IFO group had positive linear correlation to the operation time.(Pearson relation coefficient R=0.458,.P=0.021).The linear recurrence equation was:the volumes of blood lose intra-operation(ml)=172.68+1.342x(operation time).Conclusion IFO was safe to the mother.It did not affect the involution of uterus and could not increase the blood lose of postpartum and the puerperal infection morbidity.Through the effective measures of preventing postpartum hemorrhage,the postpartum blood lose of the patients that performed intrapartum fetal operation could be no more than that of the patients that had normal Caesarean section.Improving the technique of the intrapartum fetus operation and shortening the operation time are important to prevent postpartum hemorrhage.

Objective To analyze the effects of valproic acid(VPA),a histone deacetylase(HDAC)inhibitor,on macrophage polarization in?duced by paraquat(PQ)or lipopolysaccharide(LPS). Methods Mouse RAW264.7 cells were cultured at 37℃with 5%CO2,passaged,and then given one of the following treatments:(1)PQ;(2)PQ+VPA(classⅠandⅡa HDAC inhibitor);(3)PQ+apicidin(classⅠHDAC inhibitor);(4)PQ+MC1568(classⅡa HDAC inhibitor);(5)LPS;(6)LPS+VPA;(7)LPS+apicidin;(8)LPS+MC1568. The cells and culture supernatants were harvested after 8 h of treatment. RT?PCR,ELISA,and flow cytometry were conducted to assess the expression levels of macrophage phenotyp?ic markers. Results Both PQ and LPS skewed the macrophage functional polarity toward proinflammatory phenotype. VPA,apicidin,and MC1568 all inhibited PQ?and LPS?induced macrophages polarizing toward pro?inflammatory phenotype ,but the inhibitory effects were different in some ways. Conclusion VPA inhibits the proinflammatory function of macrophages induced by PQ and LPS ,but the effect of VPA on PQ?and LPS?induced macrophages has its own characteristics.

Objective: To discuss the formation mechanism of the aging characteristics of the labiomandibular fold in the lower face, through anatomical and histological study of the labiomandibular fold area. Methods: ①The methylene blue dye was injected into the jowl fat compartment and the labiomandibular fat compartment which were located in one side of the face of adult fresh cadaveric heads(5 male, 3 female), the labiomandibular fold area was the uncolored region which between the two colored fat compartments. ②Combining with the observation by eyes, symmetrical region of theobjective ly marked labiomandibular fold on the other side of the face in the same head was selected to dissect with microsurgery technique under microscope. The locations, characteristics and adjacent relationships of the anatomical structures of the labiomandibular fold were observed carefully. During the experiment, some related tissues were measured by vernier caliper and recorded by the text and image. ③The symmetrical region of the marked labiomandibular fold with the methylene blue dye (step①) was cut, dehydrated, imbedded in paraffin and serially sliced in cross-section with the thickness of 10 μm. After that, the sections were used to perform HE stain and Masson stain. Results: The labiomandibular fold is the area of the face which located in the surface of the depressor anguli oris muscle and extends from the mouth corner to the mandibular border. The superior boundary of the labiomandibular fold is formed by the cutaneous insertion of the depressor anguli oris muscle around the mouth corner. The inferior boundary is the mandibular ligament. The lateral and medial area of the labiomandibular fold are the jowl fat compartment and the labiomandibular fat compartment respectively. However, the adipose tissue of the jowl fat compartment is bigger, thicker, looser and lighter in color. Theresult of the histologic evaluation are consistent with the findings of the gross anatomy. Conclusions According to the characteristics of the labiomandibular fold, there are many aspects of reasons for the emergence of the labiomandibular fold, such as the relaxation of the facial retaining ligaments associated with the labiomandibular fold and the descensus of the lateral soft tissue of the labiomandibular fold with age. In addition, the differences in structure and morphology between the medial and lateral fat compartments of the labiomandibular fold also play a vital role.

Objective:To screen the risk factors for post-traumatic stress disorder (PTSD) after emergency trauma surgery in the patients.Methods:The medical records of emergency surgical trauma patients (traffic accident, fall, engineering accident, etc.) were retrospectively collected.The general condition and perioperative clinical indicators of the patients were recorded.The patients were divided into PTSD group and non-PTSD group according to whether PTSD occurred within 1 month after surgery.Multivariate logistic regression analysis was used to screen the risk factors for PTSD.Results:A total of 312 patients were enrolled, and the incidence of PTSD at 1 month after surgery was 19.9%.There were significant differences in preoperative VAS score, ratio of gender, intraoperative use of propofol, intraoperative use of dexmedetomidine, and postoperative ICU transfer rate between PTSD group and non-PTSD group ( P<0.05). The results of logistic regression analysis showed that intraoperative use of propofol, preoperative high VAS score and postoperative admission to ICU were independent risk factors for PTSD, and intraoperative use of dexmedetomidine was a protective factor for the prevention of PTSD ( P<0.05). Conclusions:Intraoperative use of propofol, preoperative high VAS score and postoperative transfer to ICU are independent risk factors for postoperative PTSD in the patients with emergency trauma, and intraoperative use of dexmedetomidine is a protective factor for the prevention of PTSD.
