Objective To evaluate the relationship between thyroid autoantibodies (ATA)and pregnancy outcome of infertility women after assisted reproductive technology (ART). Methods Relevant studies were identified by searching PubMed, Cochrane library, CNKI and CBM. Results 7 studies were appropriate for meta-analyses and total 4165 patiens were included. Meta analysis shows that the pregnancy rate difference between ATA positive patients and controls have no significance, but the miscarriage rate is greater significant between them. In the meta-analyses, the presence of thyroid antibodies was associated with an increased risk of miscarriage (OR 1.85, 95%CI 1.32~2.59), compared with the absence of thyroid antibodies. Conclusion Pregnant women with thyroid antibodies have an increased risk of complications, especially miscarriage. Future research,should focus on the treatment and thyroid disease on pregnancy outcome.

OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

Objective To observe the self-efficacy and body image changes of the patients with oral and maxillofacial deformity in pre-and post-operative.Methods 183 patients with oral and maxillofacial deformity and 200 relatives as control group were measured by applying General Self-Efficacy Scale (GSES) of Chinese version and Self-rating Scale of Body Image(SSBI).Postoperative satisfaction degree was scored by applying attitude measurement method of interval scale.Perioperative GSES,SSBI score,and postoperative satisfaction degree were statistically analyzed.Results GSES score (26.79 ± 5.26) was lower than that in control group in preoperative (29.69 ± 5.37),and the difference was statistically significant (P ＜ 0.05).While SSBI score (24.35 ± 8.59) was higher than that in control group(11.04 ± 6.67),and the difference was also statistically significant (P ＜ 0.05).GSES score in postoperative(29.52 ± 3.80) was significantly higher than that in preoperative (P ＜ 0.05).SSBI score in postoperative(18.88 ± 8.19) was significantly higher than that in preoperative (P ＜ 0.05).Postoperative satisfaction was comparatively lower for the patients whose GSES score was higher than 32 and 36 for SSBI in preoperative.Conclusion Oporation can enhance the self-efficacy of patients with oral and maxillofacial deformity and reduce the incidence of patients with body dysmorphic disorder tendency.

Objective To investigate the prevention and treatment of biliary cardiac reflex in the interventional treatment of obstructive jaundice.Methods Totally 600 patients with obstructive jaundice were selected and divided into group A (without any preventive measures) and group B (with prevention and treatment,injection of atropine),and each group had 300 cases.The incidence of biliary cardiac reflex was observed in two groups.The relationship between the incidence of biliary cardiac reflex and gender,age,ECG abnormalities were analyzed in both groups.The timing of biliary cardiac reflex in interventional surgery was observed.Results The incidence of biliary cardiac reflex in group A was 30.67％ (92/300),which was significantly higher than that in group B (22/300,7.33 ％),and the difference was statistically significant (x2 =53.06,P＜0.05).But there was no significant difference between group A (4/300,1.33％) and group B (0) in the incidence of severe biliary cardiac reflex (x2 =0.45,P＞0.05).The incidence of biliary cardiac reflex in both groups was not associated with gender (both Φ=0.022,P＞0.05),but the incidence of biliary cardiac reflex in both groups was positively correlated with age and ECG abnormalities (Φage =0.593,0.229,ΦEcG =0.508,0.216,all P＜0.05).The incidence of biliary cardiac reflex was the highest in the balloon catheter on the stenosis or occlusion of the expansion in group A (55.43％,51/92) and group B (63.64％,14/22),which were higher than those of in puncture and angiography (all P＜0.05).Conclusion Preoperative injection of atropine can effectively prevent the occurrence of biliary cardiac reflex in interventional therapy,meanwhile the patients' own conditions are still need to be attention.

Objective: In order to reveal the mechanisms of rh-endostatin and its suppression effect on HUVECs at different activating levels. Methods: Three types of HUVEC were prepared. We detected the ex-pression of CD105 and CD62E on the surface of adhering HUVEC, HUVEC of exponential phase of growth, and HUVEC activated with TNF-alpha. The effect of endostatin on these three types of HUVEC was indicated by the variation in the expression of CD105 and CD62E on the cells. The relationship of the changes in cell markers with the time and the concentration of endostatin was analyzed by SPSS 11.5. Results: The expres-sion of CD105 was correlated with time and dose of endostar in all groups. The expression of CD62E was cor-related with the dose of endostar in HUVEC treated with TNF-α for 24h. Conclusion: Endostatin of a certain dose can inhibit the activation of endothelial cells but it cannot induce cell apoptosis.
