Objective; To elucidate the mechanism of the role of ER-a in fat metabolism by regulating the expression of ER-a in SD rats marrow mesenchymal stem cells during differentiating into adipocytes in vitro. Methods ;SD rats marrow mesenchymal stem cells were separated and cultivated. The ER-a was transfected into the rBMSCs in group one. Tamoxifen Citrate was used to restrain the expression of ER-a in group two, the group without any treatment was used as control. Western blot was used to identify the difference of ER-a expression among different groups and Oil-Red-0 staining was employed to identify the adipocytes in vitro. Results; There was significant difference between the number of lipids and different groups (P <0. 01) ,the number of lipid droplet changed concomitantly with ER-a: Low-expression ER-a group > Control group > High-expression ER-a group. Conclusion; ER-a in SD rats marrow mesenchymal stem cells may restrain the adipocyte differentiation.

Objective:To study the difference of upper airway form and hyoid position of the adults with different vertical facial types.Methods:Cephalograms of 120 adults with different vertical facial types were retrospectively investigated by computerized cephalometric analysis.Upper airway depths and hyoid position were measured,and differences were compared between male and female,also compared among different vertical facial type groups.Results:The sagittal depth of upper airway in male was larger than that in female,but there was no statistical difference except V-LPW.Among different vertical facial types,the sagittal depths of upper airway in high angle group was smaller than that in average angle group and low angle group.There was statistical difference in hyoid position between genders,AH-SN,AH-FH and AH-C3 in male were larger than in female(P

Objective: To study the relation of condylar morphology with different vertical facial types in the development of patients with skeletal Ⅲ malocclusions. Methods:180 cases with skeletal Ⅲ malocclusion were divided into children(5-11 years old), adolescence(12-17 years old) and adult(18-30 years old) groups with 60 cases in each group. Orthopantomograms of the patients with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Condylar morphology were compared among different age groups of the same vertical facial type. Results:In patients with high angle, ramus height(RH) was getting bigger with ageing(P0.05). In patients with low angle h and RH in adult group were bigger than those in adolescence or in children(P

Objective To approach the main symptoms and pulses of excessive rising of live yang in hypertensive disease. Method The symptoms and pulses of excessive rising of liver yang in hypertensive disease were collected through clinical epidemiology. The frequency of single symptom and pulse or their combinating group was statistical analyzed by multiple factor cluster analysis and principal component analysis. Result Such symptoms and pulses as lightheadedness,headache,distention of head,tantrum,insomnia,dizzy,bitter taste of mouth,red tongue,yellow tongue fur and string pulse not only can reflect the main pathogenesis,but also are the most frequently occurring reflection. Conclusion Symptoms and pulses above are the differentiation of symptoms and signs standard for excessive rising of liver yang in hypertensive disease.

In order to lower the purchasing prices of drugs, prevent unhealthy tendencies that might arise in the process of drug circulation in the hospital, and reduce the financial burdens of patients, our hospital started from March 1997 the practice of purchasing drugs through open tender. The measures adopted include: ①establishment of a leading group in charge of drug purchases and a drug purchasing group; ②formulation and earnest implementation of the system of purchasing drugs through open tender, making “five checks”; ③standardization of the scope of routine drugs used in the hospital; and ④adherence to the system of examination and approval by the Drug Management Committee when introduction of new drugs is being considered. Since the adoption of the system of purchasing drugs through tender, the purc hasing prices of drugs have on the average dropped 14.7% and the drug expenses for single entity diseases have been lowered.

Objective To explore radionuclide bone imaging characteristics of lung cancer patients and evaluate the clinical significance of bone imaging in the diagnosis of lung cancer patients with bone metastases.Methods One hundred and seventy-seven patients with diagnosed lung cancer were examined by 99mTc -MDP bone imaging,and the symptoms,sites,quantity and pathological types of bone metastases were reviewed and analyzed.Results Total bone metastases ratio of lung cancer was 45.8%(81/177),and 85.2 % (69/81) patients had multiple bone metastases.There was a statistical significance of bone metastases in adenocarcinoma patients (69.0%,40/58),compared with patients of other types of lung cancer[squamous cell cancer (41.3%,19/46),small cell cancer ( 32.5%,13/40),undifferentiated carcinoma ( 27.3%,9/33)](P＜0.05).Bone metastases happened in 526 places: thoracic bones 212 places (40.3%),vertebras 168 places (31.9%),pelvic bones 73 places (13.9%),extremities 62 places (11.8%),and skull 11 places (2.1%).Conclusions Multiple bone metastases is more frequent in lung cancer patients.The most frequent metastatic sites are thoracic bones and vertebras.Bone metastases of adenocarcinoma is more easily than other types of lung cancer.All the patients with lung cancer should perform radionuclide bone scan,which is significant for staging,selecting therapy methods and the evaluating prognosis of the disease.

Objective To study the influence of applied times of Batroxobin on neuroprotective effects in cerebral ischemic-reperfusion(IR) injury gerbils.Methods 45 gerbils were randomly divided into five groups:normal group;cerebral IR injury model group(IR group);three times group;five times group;seven times group.The later three groups were administered Batroxobin 8 U/kg by abdominal injection q.o.d with certain times respectively.The normal group and IR group were not given drug but isometric physiological saline.Flow cytometer was used to measure apoptotic neurons of the hippocampal CA1,meanwhile electronic microscope was used to detect the ultrastrctural change of the hippocampal CA1 region.Result The quantity of apoptotic neurons in the every Batroxobin groups were significantly less than those in the IR groups(all P0.05).The ultrastrctural changes in five times group were lighter than those in three times group,but no significant difference was found between five times group and seven times group.Conclusion Three times,five times and seven times of Batroxobin can reduce the number of apoptotic neurons after IR injury.However,applied five times and seven times of Batroxobin has stronger neuroprotective effect than three times.

Setting Li Dai Zhong Yao Pao Zhi Zi Liao Ji Yao as clue, this article searched each edition of China Pharmacopoeia, National Processing Standard of Traditional Chinese Medicine issued in 1988, and relevant materials of local processing standards and modern processing study, and concluded and combed the contents about Asari Radix et Rhizoma processing in ancient and modern literature. There are records about Asari Radix et Rhizoma processing methods in history, including net processing, cutting processing, heating processing and processing excipient. However, Asari Radix et Rhizoma processing methods in modern time are relatively simple. In addition to the version of the Processing Standard of Traditional Chinese Medicines in Shanghai issued in 2008, containing the honey Asari Radix et Rhizoma, other editions of China Pharmacopoeia and processing standards only recorded net processing and cutting processing. Recent research showed that processing methods of modern stir frying processing, alkali processing, wine processing, low temperature ultrafine comminution processing and so on, can effectively reduce the toxicity of Asari Radix et Rhizoma and enhance the safety of clinical application. This article summarized the history and research progress of Asari Radix et Rhizoma processing, and provided a reference for the study on modern processing.
