Objective:To investigate the effects of iron sucrose combined with recombinant human erythropoietin(EPO)on perioperative anemia and early functional recovery in elderly patients with intertrochanteric fractures.Methods:A retrospective comparative analysis was performed on 78 elderly patients who received PFNA treatment for intertrochanteric fractures in our hospital from July 2016 to December 2018.In the observation group, 40 cases were treated with iron sucrose combined with erythropoietin during the perioperative period.No perioperative intervention measures were taken for the control group.Hemoglobin(Hb)levels at 1, 3, 5, 7 days and before discharge and Harris scores of hip joints before surgery, 2 weeks and 3 months after surgery were compared between the two groups.Results:Hb levels were higher in the observation group than in the control group at 5 d[(98.8±8.6 g/L vs.92.2±8.5 g/L, t=3.389, P=0.001)]and 7 d[(105.4±8.9)g/L vs.(94.8±8.5)g/L, t=5.370, P=0.000]after surgery and before discharge[(115.4±8.6)g/L vs.(100.6±8.2)g/L, t=7.771, P=0.000]. Harris scores were higher in the observation group than in the control group 3 months after surgery(82.4±3.8 vs.75.8±2.5, t=8.933, P=0.000). Pearson' s correlation analysis showed that Hb levels at 5d and 7d after surgery were positively correlated with Harris scores at 3 months after surgery.Hb levels before discharge had an effect on Harris scores at 3 months after surgery. Conclusions:The combined administration of iron sucrose and EPO perioperatively can promote postoperative Hb recovery, reduce the incidence of anemia, accelerate early functional recovery and improve the quality of life in elderly patients with intertrochanteric fractures.

BACKGROUND:Bone morphogenetic protein (BMP) has strong osteoinductibility. At present, it becomes a hot topic to find a proper carrier for BMP. Calcium phosphate cement (CPC) may become a favorable carrier for BMP for its many merits. OBJECTIVE: To evaluate using the CPC/BMP composite as well as only CPC to repair experimental avascular necrosis of femoral head (ANFH).DESIGN: A randomized controlled experimental study SETTING: Experimental Animal Laboratory of the 208 hospital of Chinese PLAMATERIALS: The subjects were 24 healthy adult rabbits of either sex,weighing 2.5-3.0 kg. BMP was provided by Research Institute of Orthopaedics, Xijing Hospital, Fourth Military Medical University of Chinese PLA. CPC was developed together by Department of Orthopaedics, First hospital of Jilin University and Department of Orthopaedics, Aichi Medical University, Japan and Mitsubishi Material Corporation, Japan)METHODS: This experiment was conducted in the Animal Laboratory,the 208 Hospital of Chinese PLA between April 2003 and April 2004.The CPC/BMP composite was constructed by combining calcium phosphate cement (CPC) with bone morphogenetic protein (BMP). The 24 rabbits were randomly divided into two groups: CPC group and CPC/BMP group, 12 rabbits in each group. The models of experimental avascular necrosis of femoral head (ANFH) were made. Then the CPC or CPC/BMP composite were filled into the bone defects. The specimens were harvested separately at the end of 3 and 12 weeks after operation. A series of examinations were carried out including radiograph, histomorphology, and observation under transmission electron microscope (LEM).MAIN OUTCOME MEASURES: Bone formation, degradation of materials and repairing of bone defects in each group.RESULTS:Totally 24 rabbits were examined and analyzed. ① The results of general observation and X-ray examination on the bone defect regions in two groups: at week 12 in CPC group much new bone formed, the volume of CPC decreased. In CPC/BMP group more new bone formed. The phenomena of degradation and absorption were evident and the volume of the material decreased evidently. ② The results of histology observation and transmission electron microscope (TEM) observation in femoral heads in two groups: at week 12 in CPC group CPC decreased and there were some interspaces between CPC and new bone. New bone trabecula enlarged. Juvenile osteocytes could be found with round nucleus, chromatin deviating to one side, rough endoplasmic reticulum (rER) swelling and there were the phenomena of mitochondrion vacuolated and mitochondrial cristaes broken. In CPC/BMP group, CPC was dispersed with new bone intruded into the material and enwrapping each other. Osteoblasts contacted with CPC granules tightly whose rER and mitochondrion in cytoplasm increased and swelled. Many capillaries invaded the material and were encircled by many osteoblasts.CONCLUSION: CPC is an ideal carrier to BMP. The CPC/BMP composite has stronger steoconductibility and osteoinductibility in ANFH repairing than CPC, and is effective in repairing experimental avascular necrosis of femoral head.

Objective To investigate the predictive factors of long-term outcome of cerebral venous sinus thrombosis (CVST).Methods The clinical data of 26 patients with CVST were analyzed retrospectively.The clinical outcome was assessed with the modified Rankin Scale (mRS) at 6 months after symptom onset.Univariate and multivariate analysis were used to determine the independent predictors of the long-term poor outcome.Results The mRS scores for 26 patients with CVST:0 to 1 in 19 cases,2 in 2 cases,3 to 5 in 3 cases,and 6 in 2 cases.19.2％ of patients had poor outcome (mRS score,≥3),and the mortality rate was 7.7％.The survivors did not have any recurrence within 6 months.Univariate analysis showed that disturbance of consciousness,papilloedema,cerebral edema,and cerebral deep venous thrombosis were the possible risk factors for poor outcome,while headache was the main clinical manifestation,which was negatively correlated with the poor prognosis.Multivariate regression analysis showed that disturbance of consciousness was an independent predictor of poor outcome in patients with CVST (odds ratio,48.0,95％ confidence interval 2.311 to 997.176,P =0.012).Conclusions The long-term outcome of the patients was better,disturbance of consciousness was an independent predictor of poor outcome at 6 months after the onset.

Objective To make a bioinformatical analysis of the specific allergen pTSX1 cDNA clone obtained from Humulus pollen in allergic asthma by immunological screening and gene cloning. Methods Bioinformatical approaches, including sequence analysis, sequence alignment, genetic makeup, protein structure and function prediction, were used. Results The analysis of the specific allergen pTSX1 cDNA showed that the gene had no reading frame and coded a protein with 204 amine acids. The analysis of amine acids sequence coded by the pTSX1 cDNA showed that the protein identity of this gene product might be one of ribosomal proteins. Conclusion The pTSX1 cDNA cloned from Humulus pollen in allergic asthma is a new gene, and the protein coded by pTSX1 gene may be one of ribosomal proteins.

Two regression models, based on panel data over the period of 2000-2011, are built and used to analyze what factors determine China's exports of primary and semi-finished products of traditional Chinese medicine to ASEAN. The results indicate that, China GDP, the ratio of ASEAN to China GDP per capita, average export price, the ratio of state-owned assets to total assets, have a significant positive influence on the export volumes of primary products of Chinese medicine. At the same time, RMB appreciation, the ratio of three kinds of foreign-invested assets to total assets, China-ASEAN Early Harvest Program, ASEAN-China Free Trade Area have a significant negative influence. In respect of the export volumes of semi-finished products of Chinese medicine, the significant influential factors are ASEAN GDP and the ratio of ASEAN to China GDP per capita. The former is positive and the latter is negative. In order to optimize the commodity composition of experts, it is needed to increase export volumes of both primary and semi-finished products of Chinese medicine. According to the analysis above, some proposals are put forward, such as, improving the performance of foreign capital, playing an exemplary and leading role in technological innovation by state-owned enterprises, taking advantage of bargaining power of suppliers, increasing outward foreign direct investment.

AIM:To study the visual acuity and refractive status of students pupils and middle school students in Shenzhen, and to provide a scientific basis for the prevention and control of myopia.
METHODS:A cluster sampling method was used to select five primary school students(6 737) and three junior middle school students(1 925) from Shenzhen. The visual acuity, anterior segment, fundus, eye position, and refractive status were measured. Information on associated factors for poor vision were also obtained using a questionaire. The risk factors of poor vision and the rate of myopia between grade or gender were analysed by Chi-square test.
RESULTS:The rate of poor vision was 67. 0%. Female, family history of high myopia, long time of continuous look near, short time of outdoor activities were the main risk factors. The rate of emmetropia, hyperopia, astigmatism and myopia were 15. 1%, 11. 3%, 11. 0% and 62. 6% respectively. Emmetropia, hyperopia and astigmatism incidenece rate decreased with age growing, but myopia incidence rate was increased. There were significant differences between adjacent two grades in myopia(χ2=7. 338-45. 018, P<0. 05 ) except the primary grade six and the junior grade one. There were significant differences between boys ( 61. 0%) and girls ( 65. 5%) in myopia(χ2=17. 180, P<0. 05).
CONCLUSION:The rate of poor vison is pretty high in students of Shenzhen aged between 5 to 16 years old, and myopia is the main reason. The development rate of myopia is increased with age. Early management of myopia may play an important role in controlling poor vision in students.
