SUMMARY In recent years, successful pregnancies in renal transplant women have been reported worldwide. However, pregnancy in renal trasplant recipient is relatively rare in China. This paper reported a case of pregnancy 2 years post renal transplant. At the end of 28 weeks' gestation she had abnormal liver and renal function complicated with severe preeclampsia. Literatures were reviewed on considerations about pregnancy in renal transplant women. Maternal and neonatal outcomes can be improved by intensive care during pregnancy, proper immunosupression and timely termination of pregnancy.

There have been problems in the existing multiple physiological parameter real-time monitoring system, such as insufficient server capacity for physiological data storage and analysis so that data consistency can not be guaranteed, poor performance in real-time, and other issues caused by the growing scale of data. We therefore pro posed a new solution which was with multiple physiological parameters and could calculate clustered background data storage and processing based on cloud computing. Through our studies, a batch processing for longitudinal analysis of patients' historical data was introduced. The process included the resource virtualization of IaaS layer for cloud platform, the construction of real-time computing platform of PaaS layer, the reception and analysis of data stream of SaaS layer, and the bottleneck problem of multi-parameter data transmission, etc. The results were to achieve in real-time physiological information transmission, storage and analysis of a large amount of data. The simulation test results showed that the remote multiple physiological parameter monitoring system based on cloud platform had obvious advantages in processing time and load balancing over the traditional server model. This architecture solved the problems including long turnaround time, poor performance of real-time analysis, lack of extensibility and other issues, which exist in the traditional remote medical services. Technical support was provided in order to facilitate a "wearable wireless sensor plus mobile wireless transmission plus cloud computing service" mode moving towards home health monitoring for multiple physiological parameter wireless monitoring.

Objective To investigate and compare the biomechanical stability between anatomical and overlapping reconstruction of the greater tuberosity in cadaveric humeral head replacement model. Methods Eight pair (16) fresh-frozen shoulder cadavers were match-paired into 2 groups. Four-part fracture model was created in all cadavers. Standardized humeral head replacement procedure was carried out in all specimens, and anatomical and overlapping reconstruction of the greater tuberosity was applied to each group respectively. Custom mounting apparatus and fixation jigs were designed for designated shoulder motion. A Binocular 3D Computer Vision metrical method was employed to measure the displacement of greater tuberosity relative to the humeral diaphysis. Results When the shoulder was external rotated to neutral position, the mean displacement of greater tuberosity in anatomical reconstruction group was (1.81?1.75) mm,while the mean displacement was (3.23?2.91) mm in overlapping group. Statistical difference was found between the 2 groups. When the glenohumeral joint was elevated to 30? and 60? forward flexion, the mean displacement of greater tuberosity in anatomical group was (4.01?5.00) mm and (5.99?6.97) mm respectively, while the mean displacement was (3.02?5.27) mm and (6.97?7.00) mm respectively in overlapping group. No statistical difference was found between the 2 groups during forward flexion measurement. Conclusion In cadaveric humeral head replacement model, anatomic greater tuberosity reconstruction shows better mechanical stability compared with overlapping reconstruction during external rotation to neutral position. This result suggests that there may be some loss in mechanical stability in overlapping fixed greater tuberosity. Even though standardized postoperative rehabilitation protocol are strictly followed, evident displacement of the greater tuberosity was detected. Postpone of the postoperative rehabilitation program after humeral head replacement for a decent period of time may benefit tuberosity healing.

The shoulder is a complex joint which consists of sternoclavicular joint, clavicle, acromioclavicular joint, scapula, glenohumeral joint,proximal humerus and scapulothoracic joint. It is important for us to have a good knowledge of the normal biomechanics of the shoulder when we treat shoulder problems. So this article intends to help its readers to get familiar with the characteristics of functional anatomy, biomechanics and motion of the shoulder under physiological condition.

Objective To compare the results of locking intramedullar nail and Locking plate in treating proximal humerus fractures and discuss features of each instrument. Methods A total of 54 patients with fresh two-part surgical neck fracture of proximal humerus were divided into intramedullar nail fixation group(26 patients)and locking plate fixation group(128 patients).with no statistical difference upon age,gender and dominate hand involvement in two groups.At final follow-up,physical examination and X-ray films were used to evaluate fracture healing of shoulder ioint.In the meantime,VAS score,ASES score,Constant-Murley score,UCLA and SST questionnaire were used to evaluate the function of the shoulder in two groups. Results All fractures were healed basically within 8 weeks postoperative-ly.No infection or av&scular necrosis were fouml during follow-up.The incidence rate of complication in locking plate fixation group was higher than that in intramedullar nail fixation group.Both groups obtained satisfactory functional recovery of shoulder ioint.There was no statistieal difference in regard to active for-ward elevation,external rotation besides body,active height of internal rotation,Constant-Murley scores,and SST scores in both groups.The average ASES score and VAS score of locking plate fixation group was significantly better than those of intramedullar nail fixation group. Conclusions Both fixations can treat surgical neck fractures of proximal humerus well.Locking intramedullar nail causes less trauma to the patient while Locking plate has advantages in patients'final functional recovery.

Objective To evaluate the results of delayed proximal humeral fractures treated by open reduction and internal fixation. Methods From January 2005 to July 2008, 26 patients with delayed proximal humeral fractures were treated by open reduction and internal fixation. There were 11 males and 15 females. The patients ranged from sixteen to 22-81 years old, with an average age of 49.3 years. The interval from injury to operation ranged 22 to 510 days, with a mean of 88 months. There were two-part fractue in surgical neck in 12 cases, two part in lesser tubercles of in one case,two part in greater tubercles in seven cases, three part in greater tubercles in three cases, four part in 2 cases and the splitting fracture in the head of humerus in one ease.The range of motion, VAS for pain, ASES (American sboulder and elbow surgeon's form) score, Constant score, UCLA (University of California-Los Angels scoring system)score and SST(Sim-pie Shoulder Test) for function evaluation were all recorded. The results were evaluated according to sex,age, injury side, operation times and combined injury by ANOVA.The correlation analysis was performed between operative time and results. Results The average forward flexion was 137.3°±35.1°, average exter-nal rotation was 28.9°±24.1° and internal rotation was T_(10). The mean VAS score was 0.7±1.2, the mean Constant was 83.1±17.9, the mean UCLA was 28.9±6.0, the mean SST was 8.7. There were no difference re-gaming sex, age, injury side, operation time and combined injury, fracture type and complications groups. No correlation existed between operative time and results. Conclusion It is very hard to treat delayed proximal humeral fracture due to high complication and demanding experience. With appropriate surgical technique, satisfactory results can be expected by open reduction and internal fixation.

Objective To investigate whether the patients of stroke in basal ganglia have the selective deficit of recognition of disgust expression and to test the hypothesis that basal ganglia is involved in emotion processing, especially in disgust processing. Methods We developed six typical facial emotions (happiness, surprise, fear, sadness, disgust and anger) and a neutral facial emotion. A labeling task with these emotional faces measured the ability to recognize emotional faces in 32 stroke patients in basal ganglia and in 30 normal controls.Results Compared with normal controls, patients of stroke in basal ganglia impaired in perception of facial emotion (correct identification scores, 106.73?7.62, P

The postnatal development of the ectoplasmic specialization (ES) of Sertoli cells was investigated in the rats from 1st to 8th week after birth and the adult by electron microscopy. At the end of the 1st week. ES is in the beginning of its formation. Some high electron dense materials accumulate in the submembranous regions and short cisternae of endoplasmic reticulum align in these zones. At the end of the 2nd week the short cisternae are fused each other and straight microfilaments bundles appear and are sandwiched between the flattened cisternae and cell membrane. The density of microfilaments is increased in the 3th week and numerous tight junctions appear between adjacent Sertoli cells. The ES is gradually completed in its structure until the 5th week and fully extend and circumscribed around the base of Sertoli cells. Thereafter, there is no more morphological changes. We conclude that the first 5 weeks after birth is the important period for the development of ES of Sertoli cell as well as the blood-testis barrier in rats.
