Objective To investigate the effect and safety of venlafaxine augmented with amisulpride in the treatment of major depressive disorder. Methods Fifty patients with major depressive disorder were randomly divided into control group treated with venlafaxine (n=25) and study group treated by venlafaxine augmented with amisulpride (n=25). The treatment lasted 8 weeks. Hamilton Depression Rating Scale (HAMD) and Treatment Emergent Symptom Scale (TESS) were used to evaluate the effect and safety of therapy before and 1, 2, 4, and 8-week after treatment. The serum level of IL-18 was detected at each time points in two groups. Results After treatment for 2, 4 and 8 weeks, the serum levels of IL-18 were significantly decreased in study group than that of control group (P<0.05). The serum levels of IL-18 were gradually reduced with the extended treatment time in two groups. There was no interaction between two groups and different processing times. Scores of HAMD decreased gradually after treatment in two groups. Scores of HAMD were significantly lower after treatment than that before treatment in study group (P<0.05). Scores of HAMD were significantly lower after treatment than that before treatment except for one-week treatment in control group (P<0.05). There were no significant differences in HAMD scores before treatment and one-week treatment of two groups. Scores of HAMD were significantly lower 2,4 and 8 weeks after treatment in study group compared with those of control group (P<0.05). There was a interaction between groups and processing times (P<0.05). The effective rates increased in study group (96%) than control group (76.0%). The adverse effects were less in two groups. Conclusion The low dose of amisulpride helps to improve the efficacy of venlafaxine in the treatment of major depressive disorder, which has good security and can inhibit inflammatory reaction.

Objective To inverstigate the efficiency and safety of transcatheter uterine artery embolization (TUAE) as well as the pathological changes and it′s significance after embolization. Methods 44 cases of uterine fibroids were treated by TUAE using lipiodol pingyangmycin emulsion (LPE) and Gelfoam sponge paeticles. Seven of 44 cases underwent hysterectomy or myomectomy from 1 to 6 weeks after TUAE.The specimens were studied to observe pathological changes of fibroids and myometrium. 37 of 44 patients were followed up for 1 to 6 months to observe the changes of fibroid size and uterine volume. The changes of ovarian function and myometrium after TUAE were found out by observation on mensis, test of ovarian hormone, premenstrual diagnostic curettage and pathology of the resected specimens. Results Total improvement of symptams occurred in 91.9%(34/37), including control of menorrhagia in 91.4%(32/35), disappearance of lumbago and lower abdominal pain in 85 3%(29/34),relief of freguency and urgency of micturition in 50.0%(7/14). Average decrease of fibroid and uterine volume at 6 months after TUAE was 61.3% and 50.6% respectively. No amenorrhea happened. Premenstrual diagnostic curettage showed secretory endomtrium. There was no significant difference in ovarian hormon level befor and after embolization. Pathological study showed that lipiodol was found to deposit in fibroids and was not seen in myometrium. Spotty necrosis 2 weeks occurred in fibroid and extensive patchy necrosis 3 weeks after embolization. The necrotic area became larger with elapse of time postoperative. Necrosis was not seen in myometrium. Conclusion TUAE is a new ,and effective procedure for uterine fibroid and LPE as an embolizing agent is safe without damage on myometrium.

Objective To observe the influence of telephone follow-up and home follow-up on compliance behavior and activities of daily living (ADL) of stroke patients during rehabilitation. Methods 50 cases were as telephone follow-up group and 50 cases were as home follow-up group extracted from 355 stroke patients who discharged the hospital during August 1, 2010 to July 1, 2012. They were followed up 2 weeks, 1 month and 3 months after discharge respectively. Their ADL were assessed with Bathel index (BI) at discharge and 3 months after discharge, and the compliance behavior were assessed 3 months after discharge. Results There was no significant difference in the score of BI between 2 groups at discharge (P>0.05), and the score of BI improved in both groups 3 months after discharge (P<0.05), but it was higher in the home follow-up group than in the telephone follow-up group (P<0.05), as well as the rate of compliance behavior (P<0.01). Conclusion Regular home follow-up can improve the compliance behavior of stroke patients during rehabilitation.

Objective To investigate the clinical effect of dorsal carpometacarpal reversed island flap with dorsal metacarpal nerve to reconstruct finger. Methods We designed the dorsal reverse carpal and metacarpal island flaps with nerve by using the adjacent two dorsal matacarpal arteries as blood-supply and applied the stand of bone and tendon in waste finger or the free iliac transplantation to reconstruct the every sensory finger. Results Eighten cases were survived completely, and the skin degloving injuries of the finger in 3 cases. The maximum of the flap was 9cm by 8cm. Patients were followed up 3 months to 2 years,7 weeks later pain sense of reconstructed finger was recovered. Sensation over S3 amounts to 89% of the digits. Two-point-discrimination of the digits was 5-10mm. After the operation, the reconstructed finger obtained good appearance, the sensory recovery approach normally. The patients have ability to fulfil daily activities. Conclusion This method has advantages as follow:simple and practical,high survive rate,low impairment,sensible and good appearance.

Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

OBJECTIVEThis study aims to survey the cognition and acceptance of implant dentures among Chengdu residents in 2005 and 2013 and to comparatively analyze the differences and influencing factors.

METHODSA questionnaire was designed for this study. Its main content included basic demographics of respondents (gender, age, cultural level, and income level), cognition level of implant dentures (concept and main characteristics of implant dentures), main concern of respondents regarding implant dentures and medical institutions, and acceptance level of the price of implant dentures, among others. The sampling survey was carried out among Chengdu residents in 2005 and 2013 using the designed questionnaire. The results were then statistically analyzed.

RESULTSUp to 908 valid questionnaires in 2005 and 905 valid questionnaires in 2013 were obtained. The level of cognition of implant dentures was higher in 2013 than in 2005, and the correlation between cognition and cultural level and that between cognition and income level were both positive. However, the correlation between cognition and age was negative. The success rate for implant dentures and medical treatment technology of medical institutions were the factors that the respondents were mainly concerned with. The main methods for disseminating information on implant dentures were the internet, television, newspapers, magazines, and introduction by friends.

CONCLUSIONWith the development of the society's economy and the improvement of culture and income level of Chengdu residents, the cognition and acceptance level of implant dentures have gradualy increased. Meanwhile, health education and medical technology still need to be strengthened.

ObjectiveTo explore the effect of different hypoxic duration on the brain white matter injury.Methods ewborn rats were randomly divided into two groups, normal group (n=24) and model group (n=45). The model group was di-vided into 3 subgroups (n=15) according to the time of hypoxia (50 min, 70 min, and 90 min). The animal model of white matter injury was established by unilateral carotid artery ligation in model group. After different duration of hypoxia, the mortality rate was recorded, the morphological changes of brain pathology was observed by hematoxylin eosin (HE) staining, myelin basic pro-tein (MPB) of white matter was detected by immunolfuorescence staining and motor function was evaluated by climbing slope test.ResultsThe mortality rates signiifcantly increased with prolonged hypoxia. The mortality rate was as high as 60% in 90 min subgroup. The HE staining showed that there were no obvious injury in 50 min subgroup, selective white matter injury on the operative side appeared in 70 min subgroup, and a wide range of infarction of white matter, hippocampus, and cortex appeared in 90 min subgroup. MBP semi-quantitative scores of white matter injury were higher in 70 min subgroup (3.89 ± 0.47) and 90 min subgroup (4.72 ± 0.57) than that in the normal group (0.06 ± 0.24), the difference was statistically signiifcant (P <0.05). In climb-ing slope test, the subgroups had different degrees of motor dysfunction on affected side with 90 min subgroup being the most serious.ConclusionsWhite matter injury model could be established by unilateral carotid artery ligation, and different hypoxic duration signiifcantly affects the range and degree of injury.

Objective To investigate the changing and correlation between PaCO2 and PETCO2 during laparoscopic colorectal surgery. Methods Thirty ASA Ⅰ-Ⅱ patients scheduled for laparoscopic colorectal surgery were accepted general anesthesia and trachea cannula. Hemodynamic measurements, respiratory parameters and artery blood gas analysis were drawn at 5 min after intubating, 5 min, 30 min and 60 min after pneumoperitoneum, before the side-incisions were opened and the end of operations. Results The operation time was (216.1±39.1) min, pneumoperitoneum time was (117.3±11.5) min. Comparing to the data after pneumoperitoneum, there were differences among the parameters of circulating dynamics, but the values were acceptable, pH was decreasing with time, except 5 min after pneumoperitoneum, it was significantly decreased 30 min after pneumoperitoneum until the end of operations, compared with pre-intlation value (P<0.01), pH withdrawn a little at the end of the operations. The PETCO2 and PaCO2 at different times after pneumoperitaneum were significantly higher compared with pre-inflation value (P<0.05 or<0.01). They were increasing with the time of pneumoperitoneum, and withdrawn a little at the end of the operations. There was a good correlation between PETCO2 and PaCO2, although the correlation was worst after deflation. Conclusions The circulation dynamics are stable, the correlation of PETCO2 and PaCO2 is good during the laparoscopic colorectal surgery, PaCO2 may exceed the normal value after long-term of penumoperitoneum. It is necessary to monitor the blood gas analysis during such surgeries.
