Synuclein-γ (SNCG) is overexpressed in many advanced stages cancers, including breast cancer, ovarian cancer, prostate cancer, lung cancer, liver cancer, esophagus cancer, and colon cancer.SNCG stimulates the proliferation, metastasis, and drug resistance of tumor cells, through interacting with BubR1 and damage mitotic checkpoint. A peptic ANK targeted at SNCG can inhibit activity of SNCG and may be developed as an adjuvant therapy.

Objective To investigate the clinical value of INSURE technology in very low and extremely low birth weight infants requiring respiratory support.Methods From June 2010 to August 2012,83 cases of very low and extremely low birth weight infants who had difficulty in breathing and required respiratory support were admitted into First Hospital of Tsinghua University and divided into two groups:INSURE group (n=41) and mechanical ventilation (MV) group (n=42).Infants in INSURE group accepted intubate-pulmonary surfactant-extubate to continuous positive airway pressure and those in MV group accepted intubation with or without pulmonary surfactant treatment,and mechanical ventilation without extubation.Arterial blood gases at 1 h and 12 h after treatment were compared between the two groups by t test.The incidence of respiratory distress syndrome,ventilator associated pneumonia,air leaking,chronic lung disease,intracranial hemorrhage,retinopathy,leukoencephalomalacia disease were compared with Chi-square test.Hospitalization costs,duration of ventilation,oxygen inhalation and hospital stay were compared by rank-sum test.Results (1) PO2 in INSURE group after one hour of treatment were (78.7 ±11.5) mm Hg(1 mm Hg=0.133 kPa),which were higher than those before treatment [(50.1 ±10.8) mm Hg,t=9.737,P＜0.05]; while PCO2 was lower[(48.3±8.9) mm Hg vs (54.9±11.5) mm Hg,t=-3.428,P＜0.05].PO2 in MV group after one hour of treatment were (80.2±10.0) mm Hg,which were higher than those before treatment [(51.3±9.8) mm Hg,t=10.093,P＜0.05]; while PCO2 was lower[(45.6±9.5) mm Hg vs (57.1±12.8) mm Hg,t=-4.526,P＜0.05].(2) There were no difference in PO2 and PCO2 between the two groups after one hour of treatment (P＞0.05).After 12 hours of treatment,no differences were found in PO2[(89.4±11.5) mm Hgvs (90.2±10.8) mm Hg,t=0.093] and PCO2[(44.2±5.9) mm Hg vs (39.1± 7.3) mm Hg,t=0.126] between INSURE group and MV group (P＞0.05 respectively).(3) The incidence of ventilator associated pneumonia,air leaking,intracranial hemorrhage and chronic lung disease in INSURE group were 7.3％ (3/41),4.9％ (2/41),4.9％ (2/41) and 4.9％ (2/41),which were lower than those in MV group [34.1％ (14/42),x2=27.470; 16.7％ (7/42),x2=8.651;19.0％ (8/42),x2 =8.814; 11.9％ (5/42),x2 =4.275](P＜0.05 respectively).Duration of ventilation,oxygen inhalation,neonatal intensive care unit stay in INSURE group were 5 d (3-7 d),8 d (5-11 d) and 16 d (11-25 d),which were all shorter than those of MV group [8 d (4-12 d),Z=-1.947; 12 d (8-22 d),Z=-2.013; 21 d (12-35 d),Z=-1.782](P＜0.05 respectively).Conclusions INSURE technology could be used in very low and extremely low birth weight infants because of less invasiveness,fewer complications,safety and low-cost.

Acupuncture analgesia, as a non-drug analgesic therapy, is widely used in the perioperative period clinically. In recent years, acupuncture analgesia in perioperative period is mainly used for preoperative sedation, intraoperative auxiliary anesthesia and postoperative analgesia, prevention of nausea and vomiting after surgery and perioperative complications, etc. This paper summarized its application law, influence factors, and the existing problems.

Objetive To investigate a method of collecting lung cancer cells with bronchofibroscopic biopsy for primary culture and to improve the success rate of primary culture. Methods Thirty lung cancer specimens were obtained through bronchoscopic biopsy for primary culture. The correlation of cancer morphology under bronchofi-broscopy and success rate of primary culture was analyzed. Results Among the lung cancer specimens obtained through bronchoscopic biopsy, primary culture was successful in 17 of 30 cases (56.67%) . The success rate of cauliflower-like tumor mass under bronchofibroscopy was 84.62% (11/13) . The success rate of infiltrating tumor mass under bronchial mucosa with luminal stenosis with or without cristate were 66.67% (2/3) and 37.5%(3/8), respectively. The primary culture of a globular and stiff tumor mass was successful only 1 in 6 cases (16.67%) .Conclusions The primary culture of lung cancer cells obtained from bronchofibroscopic biopsy is simple and effective with a total success rate of 56.67%. Furthermore, the success rate of primary culture is signifi-cantly correlated with the cancer morphology under bronchofibroscopy.

Objective To evaluate the clinical effect of acupuncture combined with estazolam for the treatment of primary insomnia with heart and spleen deficiency type. Methods Seventy qualified patients were randomized into treatment group and control group, 35 in each group. Both groups received oral use of estazolam before bed time for 6 continuous weeks, and acupuncture group was additionally given acupuncture for regulating governor vessel and tranquilizing spirit on acupoints of Baihui(GV20), Yintang(GV29), Shenting(GV25), Anmian (EX-HN22), Shenmen(H7), Sanyinjiao(SP6), 3 times a week and lasting for 6 continuous weeks. The sleep state of the patients was estimated according to Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and Athens Insomnia Scale(AIS) before treatment, on the third and the sixth week of treatment, and one month after the completion of treatment. Results (1) Five cases in the treatment group and 3 cases in the control group were dropped out for not completing the treatment timely. In the end , 30 cases in the treatment group and 32 cases in the control group finished the trial. (2) The total effective rate in the treatment group was up to 90.0%, and was 71.9% in control group, the difference being significant(P<0.01).(3) Compared to the control group, the scores of PSQI, ESS and AIS were much decreased in treatment group on the third and the sixth week of treatment , and one month after treatment(P<0 . 05 or P<0 . 01). Conclusion Acupuncture for regulating governor vessel and tranquilizing mind combined with oral use of estazolam exerts certain therapeutic effect for the treatment of heart and spleen deficiency type insomnia, and the effect was superior to that of estazolam alone.

The treatments for insomnia after stroke were various in recent years, including acupuncture with its distinguishing feature. It’s reviewed and summarized that experimental researches on Chinese and English databases about acupuncture treatment of insomnia after stroke in recent 10 years. Clinicians had chosen different acupuncture therapies for insomnia after stroke according to yinyang, zangfu, meridians, opening and closing of qi activity. Although those acupuncture therapies had achieved obvious clinical effects, they were deficient in experimental design and methodology.

Objective To observe the clinical efficacy of surround electroacupuncture in relieving pain after operation for mixed hemorrhoids. Method Seventy-two patients with mixed hemorrhoids were randomized into a treatment group and a control group, 36 cases in each group. The two groups both received the corresponding interventions once in 15 min after the operation: the treatment group received electroacupuncture treatment, and the control group was only placed in a simulated environment of electroacupuncture but without receivimg any needling treatment. The pain intensity was evaluated by using Verbal Rating Scale (VRS), Wong-Baker Faces Pain Rating Scale, and Visual Analogue Scale (VAS) at 11 different time points after the treatment: once every 1 h in 8 h after the treatment, once at the first defecation, once respectively 24 h and 48 h after the treatment. The data were statistically analyzed afterwards. Result At 3 h and 4 h after the treatment and at the first defecation after the treatment, the VRS scores of the treatment group were significantly lower than that of the control group (P<0.05); respectively at 4 h, 5 h, 6 h, 7 h, and 8 h after the treatment and at the first defecation, the Wong-Baker scores of the treatment group were significantly lower than that of the control group (P<0.05); respectively at 2 h, 3 h, 4 h, 5 h, 6 h, 7 h, and 8 h after the treatment, at the first defecation, as well as at 24 h after the treatment, the VAS scores of the treatment group were significantly lower than that of the control group (P<0.05); it indicates that the pain intensity of the treatment group should be lower than that of the control group at the above time points, and the analgesic effect in the treatment group lasts a longer time, running a lower risk of losing effectiveness compared to the control group (P<0.05). Conclusion Real-time acupuncture treatment after the operation is significantly effective in relieving pain after operation for hemorrhoids.

Objective To study the effects of previous analgesia of acupuncture on patients with the mixed hemorrhoid surgery pain.MethodsA total of 70 patients with mixed hemorrhoid treated with “Milligan-morgan hemorrhoids” were randomly divided into treatment group and control group, 35 patients in each group. The treatment group was treated 30 min prior to the surgery with needling and manipulating Baliao, Chengshan, Hegu every five minutes until the operation, while the control group was not treated before the operation. The patients were assessed by Visual Aualogue Scale and self-reporting Inventory.ResultsAfter the operation, the treatment group was significantly better than the control group in the outcome index of beginning time of pain (14.3 ± 4.9 hvs. 4.2 ± 2.3 h, Z=-5.666,P<0.01) and peak time of pain (17.3 ± 4.5 hvs. 6.0 ± 2.9 h,Z=-5.581,P<0.01). The treatment group was significantly better than the control group in decreasing the pain beginning VAS score (3.3 ± 1.7vs. 4.6 ± 1.7,Z=-2.820, P<0.01) and pain peak VAS score (4.5 ± 2.0vs. 6.5 ± 1.2,Z=-4.025,P<0.05). After surgery, the treatment group was significantly better than the control group in decreasing the score of Self-reporting Inventory scale at the 1stday (1.8 ± 1.3vs. 3.0 ± 1.3),Z=-3.472,P<0.01) and 2ndday (1.2 ± 0.9vs. 1.9 ± 1.2,Z=-2.464,P<0.05). And the treatment group was significantly better than the control group inreducing the quantities of compound aminopyrine phenacetin tablet (0.5 ± 0.9vs.1.5 ± 1.7,t=3.167,P=0.002).ConclusionAcupuncture analgesia 30 minutes prior to the mixed hemorrhoid surgery can significantly reduce the postoperative pain.

Objective To investigate cervical spinal upper motor neuron (UMN) dysfunction in patients with frail arm syndrome (FAS) by physical examination,triple stimulation technique (TST) and pectoralis tendon reflex tests.Methods Sixty-seven FAS patients,coming from Peking University Third Hospital from June 2013 to June 2016,underwent physical examination and routine electrophysiological tests.The pyramid signs,the results of pectoralis tendon reflex and TST were collected to estimate the function of cervical spinal UMN.Results On the time of diagnosis,weakness of bilateral proximal upper limbs was found in 61 patients,while weakness of unilateral proximal upper limb was found in six patients.There were 25 patients with tendon hyperreflexia,20 patients with tendon hyporeflexia and 22 patients with tendon areflexia.All the patients were pectoral muscle tendon hyperreflexia except one.UMN score of cervical region was 2.0 ± 0.5.Lower motor neuron score of cervical region was 2.0 ± O.2.The amplitude ratio of TSTtest/TSTcontrol was 78.31％ ± 6.52％.The latency and amplitude of quantitative detection of pectoralis tendon reflex was (7.80 ± 1.22) ms and (1.23 ± 0.14) mV,respectively.In the follow-up study,the tendon reflexes and the UMN score declined,the amplitude ratio of TSTtest/TSTcontrol decreased,while the lower motor neuron score increased and the latency of quantitative detection of pectoralis tendon reflex remained almost unchanged.Conclusion The results showed that there was cervical spinal UMN dysfunction in patients with FAS,and the pyramid signs were often concealed by muscle atrophy with progression of the disease.

BACKGROUND: The full three-dimensional finite element model can not only establish a realistic three-dimensionalmodel, but also can simulate the osteotomy on the model. Analysis of biomechanics guides the clinical operation.OBJECTIVE: To establish a three-dimensional finite element model of ankylosing spondylitis kyphosis and provide an effective digital platform for further studies.METHODS: A 30-year-old male patient with ankylosing spondylitis kyphosis participated voluntarily in the current study. CTimages obtained from CT transverse scanning from C1 to the sacrococcyx were imported into Mimics 17.0 software toestablish a three-dimensional geometric model of the posterior spine. The geometric model was then imported into Studio Geomagic 2013 software. For the subsequent optimization of image processing, the posterior spine convex geometry wasestablished on the three-dimensional geometric model. We used Unigraphics NX 8.5 to establish the spinal kyphosis surfacemodel, then added modeling of calcification of the ligaments, partial resection of useless sacral bone, and finally, imported themodel into ANSYS 15.0 finite element analysis software, then added the ligaments and set the parameters of the material,generating a complete three-dimensional finite element model of ankylosing spondylitis.RESULTS AND CONCLUSION: A three-dimensional finite element model of complete ankylosing spondylitis wassuccessfully established. Using the ten-node approach, we generated 398370 tetrahedral elements, and 668538 nodes.This will provide a reliable digital platform for the next step of biomechanical analysis.
