Hp phenotypes were determined by polyacrylamide disc-electrophoresis in sera from 555 individuals of Han population in Kunming. HP phenotype frequencies were simillar to that of Shanghia, Quandong Han Population and the other six phenotypes (1-p,2-1F, F K etc) could be detected in Kuming population by the same method.

BACKGROUND:Three-dimensional printing technique has been applied in medical fields since it was invented in the end of 20th century. Recently it has been widely used in manufacturing scaffolds for bone tissue engineering. OBJECTIVE:To review the basic concept of the scaffold for bone tissue engineering, the basic requirements for three-dimensional printing technique in scaffold engineering, different materials used in bone tissue engineering, the advantages and limitations of three-dimensional printing technique and the outlook of three-dimensional printing technique applied in manufacturing scaffold for bone tissue engineering. METHODS: The first author did a computer-aided retrieval of the MEDLINE database, Science Direct database, CNKI database, and CQVIP database for articles relevant to three-dimensional printing technique used in manufacturing scaffolds for bone tissue engineering published between January 1990 and February 2015. The key words were three-dimensional printing, tissue engineering, rapid prototyping technology, scaffold, materials in English and Chinese, respectively. Repetitive studies were excluded, and 33 of 52 related literatures were adopted in result analysis. RESULTS AND CONCLUSION: Three-dimensional printing technique has many advantages such as high resolution, high velocity and the freedom to build unlimited geometries. There are some requirements for the powder and binder used to construct bone tissue engineering scaffolds using the three-dimensional printing technique, such as the flowability, stability and wettability. A wide range of materials can be used: synthetic and natural polymers, ceramics, as wel as composites of the aforementioned. Various kinds of powder take responsibility of different features of scaffolds, resulting from the advantages and disadvantages of different materials. Although this technique has some limitations such as high cost and the difficulty of commercial production, its application stil has a bright future.

Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

Objective In order to investigate the changes of glycogen and lactate in cortex after exercise-induced central system fatigue. Methods Central fatigue model was established according to Bedford weight/maximal oxygen uptake equation. The rats were divided into three groups: control group (C), sedentary-exhausted group (SE), and overtraining group (O). Results After 1 week exercise, compared with control group, the weight of rats in SE and O group increased slowly. BUN of SE and O group increased significantly to 4.78?1.99 mmol/L and 8.48 ?0.92 mmol/L respectively,but Hb showed no changes. Compared with C group, both DA and DA/5-HT of O group decreased dynamical which were 309.04?63.68 ng/ml?g and 0.42?0.25 respectively. The latency of SEP in O group distinctly delayed, P1: 2.98?0.55ms, N1: 4.23?0.35ms, P2: 5.28?0.60ms. Regarding to 5-HT, no significant difference was found among all groups. Cortex lactate concentration of O (1.46mg/100g )and SE(1.12 mg/100g) group were significantly higher than control group(0.92 mg/100g). There was a tendency of glycogen decrease but had no significant difference among all groups. Conclusion The results suggested that lactate and glycogen might have close relationship with central fatigue and were the possible reasons to cause central fatigue.

Objective To evaluate the diagnostic value of MRCP compared with ultrasound in patients with cholangiopancreatic disease by ROC curve. Methods The data of 62 patients with suspected cholangiopancreatic disease undergoing both MRCP and ultrasound were retrospectively studied. ROC analysis was performed by ROCKIT software. Results Area under the ROC curve of MRCP was 0.739. Area under the ROC curve of US was 0. 930. ROC analysis showed that these two modalities were effective in diagnosing cholangiopancreatic disease, with MRCP being more effective than ultrasound, especially for the diagosis of lower biliary tract diseases. Conclusion MRCP combined with MRCP source images is of great help in the diagnosis of pancreaticobiliary duct diseases.

Objective To improve the efficiency of donated organs and to investigate the possi- bility and operation protocol of heart and lung transplantation from the same donor to different reci- pients.Methods The organs of heart and lung were obtained from three donors through the method of orthotopic lavage and whole cutting,and transplanted to end-stage patients with heart diseases or lung diseases.First,the donor was subjected to mechanical ventilation,thoracotomy and lavage of heart and lung.The heart and lung were cut in whole and separated.The recipients were subjected the re- trograde lavage of heart and lung.In the patients receiving unilateral lung transcription,the left and right lungs were isolated.Among 3 recipients of lung transcription,one underwent left unilateral lung transplantation and 2 bilateral lung transplantation.Three cases received orthotopic cardiac transplan- tation by using bicaval orthotopic heart transplantation (BOHT) anastomosis method.Results One recipient of left unilateral lung transplantation recovered well after operation.In one recipient under- going bilateral lung transplantation,right upper lung embolism occurred.After re-operation of cutting the right upper lung on the 9th day of the first one,he recovered from the illness.In another recipient receiving bilateral lung transplantation,anastomotic stenosis of trathea and pulmonary infection occurred after operation.After expectant treatment,he recovered from the illness,but died from serious infection 7 months after operation.One of the heart recipients was found having renal failure of first stage,and recovered from disease after hemodialysis treatment.Quality of life was good in all 3 heart recipients after operation and their heart function achieved the restoration of 0-Ⅰstage.Conclusion The treatment protocol of transplantation from the same donor to different recipients at the same time, which can make full use of the organs from donors,is feasible and has good effect.
