Objective To evaluate the effects of hypogastric artery ligation to treat massive hemorrhage in pelvic fractures with abdominal organ injuries. Methods The pelvic fractures of 16 patients were classified as Tile B type in 10 cases and C type in 6. Among them there were 6 open fractures and 20 sites of abdominal visceral injuries. The capacity of retroperitoneal hematoma, which was ruptured in 6 cases, ranged from 800 ~2 500ml with 1 400ml on average. The bleeding volume in the survivals was 1 500~5 800ml with 2 600ml on average. Ligation of bilateral hypogastric artery was carried out in all patients with intra abdominal injuries within 6h. Of them, skeletal traction was used in 7 cases while pelvic external fixation in 5 cases. Results One death occured dut to consumptive coagulopathy with hematorrhea. Of the 15 survivals, bleeding was controlled in 8 cases, decreased in 5 and uncontrolled in 2. The effective rate was 81.3%(13/16) and the survival rate 93.8%(15/16). Conclusion When emergency celiotomy is performed for abdominal injuries, a rational application of hypogastric artery ligation can play a positive role in control of pelvic hematorrhea.

BACKGROUND: The decrease of activity level of choline acetyltransferase (ChAT) and reduction of membrane protein of synaptic vesicles are the main biochemical indexes in Alzheimer disease. Traditional Chinese bushen yizhi formula is of the effects of strengthening the kidney, replenishing qi, generating marrow and nourishing the brain, its medicine-containing serum can effectively protect these changes resulting from amyloid protein.OBJECTIVE: To investigate whether the medicine-containing serum of bushen yizhi formula can improve the pathological injury of neurons induced by amyloid protein metabolites in Alzheimer disease, thus to estimate the therapeutic effect of bushen yizhi formula on Alzheimer disease.DESIGN:A randomized and controlled trial. SETTING:Institute of Neuroscience, Second Affiliated Hospital, Guangxi College of Traditional Chinese Medicine, Nanning 530011, Guangxi Zhuang Nationality Autonomous Region, China; Encephalopathic Institute of Guangzhou University of Traditional Chinese Medicine.MATERIALS:The experiment was conducted from September 2003 to March 2004 at the Research and Development Center of New Drugs of Guangxi College of TCM. Totally 60 healthy Wistar rats of clean grade,three months, were at random divided as blank control and bushen yizhi groups, with 30 in each group. The bushen yizhi formula consisted of Fructus Lycii, Fructus Cnidii, Radix Gingeng, Radix Polygoni Multiflori,Cortex Moutan Radicis, Borneolum, etc. The medicine was prepared before use as 0.176 g/Ml liquid(including 1.13 g/Ml rude drugs).METHODS:① Each of the rats in bushen yizhi group was by garage given 1.0-1.5 Ml prepared liquid per day for consecutive 30 days. Within 4hours after the last administration the serum was isolated at 5 000 r/min for 5 minutes, filtered aseptically, the compliment was inactivated at 56 ℃,then the medicine-containing serum was obtained. The rats in blank control group were given saline of the same volume, and the serum was prepared with the same method. ② For NG108-15 cells, the concentration of amyloid protein 25-35 segments in the culture liquid was 5 μ mol/L, or 1-42 segments, 200 nmol/L, was suitable. ③ NG108-15 cells was first in cubated for a day in CO2 incubator with Dulbecco-improved Eagle medium of 0.1 molarity at 37 ℃, then 5 μmol/L amyloid protein 25-35 segment or 200 nmol/L segment 1-42 was added to continuously incubate for a day, after that the cell models of Alzheimer disease was ready. Then 50 g/L medicine-containing serum or Dulbecco-improved Eagle medium of blank control group serum was taken to replace the original culture liquid, and the amyloid protein segments of the above-mentioned concentration was still added for maintaining the cell models of Alzheimer disease, after 5 days'differentiation incubation, the indexes were detected with those in non-amyloid protein as control. ④ Western blotting, radioimmunoassay and electrophysiological examination were used to investigate the ChAT activity,synapsin protein level and rate of functional synapse formation of NG108-15cells in Alzheimer disease after treatment with the medicine-containing serum of bushen yizhi formula.MAIN OUTCOME MEASURES :The effects of the medicine-containing serum of bushen yizhi formula on ChAT activity, synapsin protein level,rate of functional synapse formation of NG108-15 cells and frequency of miniature plate potential in NG108-15 cells.RESULTS:Totally 60 rats involved all entered the final result analysis.① The effect of the medicine-containing serum of bushen yizhi formula on ChAT activity: In the conditions when there was no amyloid protein or the final concentration of amyloid protein 1- 42 was 200 nmol/L, the ChAT activity in bushen yizhi group was obviously higher than that in blank control group [(1651.2±134.5), (1336.1±268.2), ( 586.1±223.4),(1290.7±381.5)μmol/(g·h); P < 0.05] . ② The effect of the medicinecontaining serum of bushen yizhi formula on synapsin protein level: The absorbance values of synapsin Ⅰa and Ⅰb, in the conditions when there was no amyloid protein, amyloid protein 25-35 and 1-42, were respectively 5.02, 1.36 and 2.46 in bushen yizhi group; and 3.18, 0.57 and 0.71 in blank control group. The values in bushen yizhi group were respectively 1.6,2.4 and 3.5times those in blank control group. ③ The effect of the medicine-containing serum of bushen yizhi formula on functional synapse formation of NG108-15 cells: In the conditions when there was no amyloid protein or amyloid protein 1-42, the levels of functional synapse formation in bushen yizhi group wereall higher than those in blank control group [(90.6±6.0)%, (63.2±17.0)%, (58.0±13.1)%, (34.2±13.0)% ;P<0.05].④ The effect of the medicine-containing serum of bushen yizhi formula on frequency of miniature plate potential in NG108-15 cells: In the conditions when there was no amyloid protein or amyloid protein 1-42, the frequencies of miniature plate potential in bushen yizhi group were all higher than those in blank control group [(9.28±4.1), (5.48 ±5.14), (5.55±5.85),(3.05±4.46)/min; P < 0.01, P< 0.05].CONCLUSION:In the conditions when there existed no amyloid protein or amyloid protein, the medicine-containing serum of bushen yizhi formula can raise ChAT activity, not only correct the decrease of cellular synapsin caused by amyloid protein, but also raise the expression of synapsin protein, the rate of functional synapse formation and neurotransmitter release under the condition of no amyloid protein. It was shown that the prescription can antagonize the pathological development of Alzheimer disease, and play the therapeutic effect through enhancing the release power of neurotransmitter.

Cholangiocarcinoma is a malignant tumor originating from the epithelial cells of the bile duct, and its incidence and mortality rates keep increasing year by year. Unknown pathogenesis of this disease has led to the difficulties in early diagnosis and treatment. With the development of genetic engineering and bioinformatics, more and more studies have found that long non-coding RNA (lncRNA) is closely associated with the pathophysiological process of cholangiocarcinoma. This article summarizes the research advances in the role of lncRNA in mediating the biological behaviors of cell proliferation, apoptosis, metastasis, invasion, epithelial-mesenchymal transition, and drug resistance in cholangiocarcinoma, as well as the association of lncRNA with clinical features and prognosis.

OBJECTIVE: To provide reference for standardization and improvement of teaching model for endocrinology speciality in community clinical pharmacists training base. METHODS: Based on the requirments of community clinical pharmacists training in Shanghai, the characteristics and contents of community clinical pharmacists training were summarized, and teaching characteriatiostics, effect evaluation and problems werer analyzed on the basis of the acutual situation in our hospital. RESULTS & CONCLUSIONS: Community clinical pharmacists training has the characteristics of training for chronic diseases, short training cycle, and support from the medical consortium platform. Its contents are theoretical learning and professional knowledge training, pharmaceutical care and medication education, case discussion, homework guidance and comment. Compared with other specility, endocrinology speciality has the characteristics of strengthening comprehensive pharmaceutical care (for example, pharmaceutical care of diabetic patients should pay attention not only to hypoglycemia, but also to hypobaric, hypolipidemic and complications), emphasizing medication treatment management (MTM) teaching (provide a series of professional services such as medication education, counseling and guidance, and medical reorganization for patients, so as to improve the safety, effectiveness and compliance of medication, and then control blood glucose, delay or avoid complications), emphasizing the cultivation of health education ability and communication ability. The evaluation of training effect included the evaluation of trainees and teachers. The former includes objective evaluation (theoretical knowledge test, bedside medication education assessment and homework assessment) and subjective evaluation (attendance, attitude, clinical practice performance). The latter is mainly scored by trainees on teachers (including professional level, teaching attitude, teaching ability and content). Through the training, it is found that the trainees’ literature retrieval ability is poor, the trainees have not clear idea to diabetic patients, the homework writing and typesetting are not standardized; the teaching teachers have less experience and teachers could not teach the students in accordance with their aptitude and provide individualized training. The training and teaching mode needed to be further improved.
