Objective To study the impact of pregnancy on differentiated thyroid cancer. Methods Retrospective comparative analysis were made between pregnancy-related thyroid cancer patients ( including nine months before delivery and one year after delivery) and the age-matched non-pregnancy-related thyroid cancer patients treated in the Department of head and neck, Fudan University Shanghai Cancer Center. Results There were 125 cases of pregnancy-related thyroid cancer patients from 1998 to 2008, including 28 cases (22.4%) of neck recurrence and metastasis after the surgery of thyroid cancer, meanwhile there were 691 cases of the agematched non-pregnancy thyroid cancer patients, including 90 cases ( 13% ) of neck recurrence and metastasis after the surgery of thyroid cancer. The rate of neck recurrence and metastasis after the surgery of thyroid cancer in the pregnancy-related group was higher than that in the non-pregnancy related group ( P ＜ 0.05). The maximum diameter of tumor in the pregnancy-related group and the non-pregnancy group is 2. 1 cm and 2.6cm respectively.There were 19 cases of multi-focal cancer ( 19.6% ) in the pregnancy-related group and 58 cases (9. 6% ) in the non-pregnant group, P ＜0.05. There were 23 patients (23.7%) of extrathyroid invasion in the pregnancy-related group and 65 patients ( 10.8% ) in the non-pregnant group, P ＜0.05. There were 67 cases (53.6%) and 35 cases (28%) of the central and lateral cervical lymph node metastasis in the pregnancy-related group respectively and 296 cases (42.8%) and 117 cases (16. 9% )in the non-pregnant group, P ＜0.05. There were 19 cases (15.2%) of extralymph invasion in the pregnancy-related group and 32 cases (4.6%) in the non-pregnant group, P ＜ 0.05. Conclusions The incidence of Extrathyroid invasion, multi-focal cancer, cervieal lymph node metastasis and extralymph invasion of the differentiated thyroid cancer is higher in pregnancy-related patients.Pregnancy may deteriorate the prognosis of thyroid cancer. For patients after the surgery of thyroid cancer, pregnancy may increase the risk of neck recurrence and metastasis. However, pregnancy does not affect the stage of thyroid cancer and the prognosis is still good.

Objective: To evaluate the prevention and treatment effects of acupuncture-moxibustion for Alzheimer disease (AD) based on various AD mouse models.Methods: Several representative types of mouse models were selected according to the pathophysiological causes of AD, including senescence accelerated mouse/prone (SAMP) mice, soluble amyloid-β protein (Aβ) injection mice/rats, amyloid precursor protein (APP) transgenic mice, and APP/PS1 double transgenic mice. Through the observation of behavioral changes and analysis of core items, the possible mechanisms of acupuncture-moxibustion in preventing and treating AD were explored. Results: Acupuncture-moxibusiton therapy can improve AD mice's cognitive dysfunction; the major action mechanisms including increasing cerebral blood flow, improving the expressions of vital proteins in the hippocampus, preventing neuron cell apoptosis, promoting the clearance of Aβ deposition, activating autophagy pathway to reduce memory deficits and regulating the metabolisms of brain-derived neurotrophic factor, tyrosine kinase receptor B, N- acetylaspartate and glutamic acid. Conclusion: Although the optimal mouse model is not determined, it is sure that acupuncture-moxibustion therapy can improve cognitive function. A more suitable AD animal model should be duplicated in order to better explore the inherent action mechanism of acupuncture-moxibustion in preventing and treating AD.

Objective To observe the expressions of efflux pump gene cluster adeAB in acinetobacter baumannii isolated from the burn patients and the expression changes of its upstream regulatory genes adeR and adeS and determine the influence of those genes on drug resistance of acinetobacter baumannii.Methods Nine drug-resistant strains and nine sensitive strains of acinetobacter baumannii isolated from the burn patients treated between June 2012 and March 2013 were used.After strain identification using 16SrDNA sequencing,acinetobacter baumannii standard strain ATCC19606 was employed as the control.mRNA expressions of efllux pump genes adeA and adeB and their upstream regulatory genes adeR and adeS were detected by real-time quantitative PCR.Results (1) adeA and adeB genes presented higher expressions in drug-resistant strains (3.71 ±0.95,76.16 ± 8.75) than in sensitive strains (0.92 ± 0.94,0.72 ± 0.78) (F =38.71,663.65 respectively,both P ＜ 0.05).(2) adeS and adeR genes showed higher expressions in drug resistant strains (18.02 ± 6.71,3.02 ± 2.69) than in sensitive strains (1.64±1.51,0.76±0.61) (F =51.04,5.57 respectively,bothP＜0.05).Conclusions The over-expression of efflux pump gene cluster adeAB induced by the expression alteration of its upstream regulatory genes adeR and adeS is closely associated with the drug resistance of acinetobacter baumannii in the burn patient.Besides,the regulatory genes may depend on adeS to sense the nosocomial environment condition,activate or inactivate adeR and hence regulate efflux pump expression.

Objective To investigate the influence of abaI expression on acinetobacter baumannii biofilm formation.Methods Acinetobacter baumannii strain S isolated from bums patients was collected for the study,while the standard strain ATCC19606 was served as the control.At 6,24 and 48 hours,the gene expressions of abaI,pgaA,pgaB and pgaC were detected by real-time fluorescent quantitative PT-PCR,secretion of N-acyl-homoserine lactones (AHLs) by biological sensor and biofilm formation by MTT method.Results (1) Gene expressions of abaI,pgaA,pgaB and pgaC at 6 hours were 8.63 ±5.93,1.98 ± 1.93,1.01 ± 1.32 and 2.67 ± 3.46 respectively,which showed a quick increase at 24 hours (22.81 ± 17.60,5.13 ± 4.32,5.66 ± 3.97,11.97 ± 7.75 respectively),followed by a rapid decline in 48 hours (3.43 ± 0.88,1.30 ± 0.24,3.01 ± 3.00,3.02 ± 3.29 respectively).Gene expressions of pgaB and pgaC at 6 hours and that of pgaA and pgaC at 48 hours revealed statistically significant differences from those at 24 hours (P ＜ 0.05).(2) AHLs showed a level of 18.49 ± 11.03 at 6 hours,reached a peak of 52.23 ± 15.95 at 24 hours,then descended to 5.53 ± 0.94 at 48 hours.AHLs level at 24 hours showed statistically significant difference from that at 6 hours and 48 hours (P ＜ 0.05).(3)Biofilm formation at 24 hours and 48 hours was 2.83 ±0.44 and 2.71 ±0.15 respectively,far higher than that at 6 hours (0.49 ± 0.11,P ＜ 0.05).(4) In the correlation analysis among AHLs,biofilm formation and gene abaI,pgaA,pgaB and pgaC expressions,significant positive correlation was found between abaI and pgaA and between AHLs and pgaC expression (P ＜ 0.05).Conclusion Acinetobacter baumannii may regulate gene expressions of pgaA and pgaC responsible for biofilm formation to adjust to the external environment by means of changing abaI gene expression and AHLs secretion.

Objective To compare the effect of thoracoscopic and laparoscopic surgery with conventional thoracic surgery on esophageal cancer and its influence on pulmonary function. Methods Ninety?four patients with esophageal cancer treated in the Second Affiliated Hospital of Chengdu Medical College from March 2010 to March 2016 were selected and were divided into the control group ( 54 cases) and the study group ( 40 cases) according to operation methods. The control group received traditional thoracotomy. The study group received thoracoscopic and laparoscopic surgery. The operation and pulmonary function indexes were compared. Results The operation time of the patients in the study group was significantly longer than that in the control group ( (218. 1±35. 8) min vs. (192. 3±40. 1) min,t=3. 23,P<0. 05). Intraoperative blood loss of the patients in the study group was significantly less than that in the control group ( (286. 4±83. 5) ml vs. (343. 7 ±96. 7) ml,t=3. 01,P<0. 05) . The number of lymph nodes cleared of the patients was significantly higher in the study group ( (18.0±5.4) node vs. (15.5±4.6) node,t=2.42,P<0.05).Thoracic drainage of the patients in the study group was significantly less than that in the control group ( (650. 3±61. 3) ml vs. (1153. 5 ±133. 7) ml,t=22. 12,P<0. 05). Chest tube pull out time in the study group was significantly earlier than that in the control group ( (5. 1±1. 3) d vs. (8. 0±1. 8) d,t=8. 65,P<0. 05). First exhaust time in the study group was significantly earlier than that in the control group ( (33. 2±6. 7) h vs. (40. 7±7. 3) h,t=5. 10,P<0. 05). Hospital stay in the study group was significantly shorter than that in the control group ( ( 13. 8 ± 2. 8 ) d vs. (18. 2± 3. 6) d, t=6. 42, P<0. 05) . Postoperative complications occurred in 4 cases in the study group, accounting for 10%, significantly lower than that in the control group, 15 cases, 27. 8%, the difference was statistically significant (χ2=4. 50,P<0. 05) . VC,FEV1 and MVV in the study group were significantly higher than those in the control group ( VC:( 81. 5 ± 15. 6 )% vs. ( 42. 3 ± 8. 1 )%;FEV1: ( 85. 7 ± 9. 1 )% vs. ( 43. 6 ±6. 8)%;MVV:(76. 0±8. 9)% vs. (48. 3±7. 6)%,t=15. 83,25. 68,16. 24,P<0. 05). 3?year survival rate of the study group and the control group were 45. 0% (18/40) and 44. 4% (24/54),respectively. There was no significant difference between the two groups (χ2 = 0. 01, P> 0. 05 ) . Conclusion Thoracoscopic and laparoscopic surgery for esophageal cancer has the advantages of small trauma,rapid recovery and low incidence of complications and obvious protective effect on pulmonary function. It is safe and feasible.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy combined with limited open repair of medial collateral ligament (MCL) for the treatment of multiple ligament injuries of knee joints.

METHODSFrom March 2006 and June 2012,the data of 14 patients (14 knees) with multiple injuries of ACL, PCL, and MCL were collected. There were 8 males and 6 females with an average age of (31.8 +/- 8.1) years old (ranged, 20 to 49 years old). All the patients were performed with X-ray and MRI examination, and the results showed that 10 patients had combined with injuries of anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL); 4 patients had ALC,PCL and posterolateral corner (PLC) injuries. Four patients had medial meniscus injuries and 2 patients had lateral meniscus injuries. The MCL,PLC and meniscus injuries were treated with operation on the first stage, and functional exercises were performed 3 weeks after fixation. The reconstruction operation of ACL and (or) PCL was performed at the second stage under arthroscopy 3 to 6 months later when the movement range of knee joint recovered to the normal level with obvious relaxation.

RESULTSAll incisions healed by primary intention. All the patients were followed up with a mean duration of 48.9 months (ranged, 24 to 80 months). The Lysholm score was improved from preoperative 19.6 +/- 0.9 to the latest follow-up 87.1 +/- 2.8 (t=12.3, P<0.01). The International Knee Documentation Committee (IKDC) rating: 9 cases nearly recovered to normal, 5 cases were abnormal.

CONCLUSIONFor multiple ligament injuries in the knee, staged repair and reconstruction can effectively restore knee joint stability and function.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.
