Marine medicine is an important part of Chinese medicine and a growth point of the development of marine economy. Current researches of marine medicine had ignored accumulated experience in clinical medicine for thousands of years of development of marine medicine and the guidance of traditional Chinese medicine (TCM) theory. In this article, we proposed a research mode of Mining experience-Clinical validation-Targets screening-Component screening-Component compatibility-Mechanism study under the guidance of the hypothesis of Nature-Effect-Material Trialism to study marine medicine. Kun Hai Jiang Xin (KHJX) Decoction is a marine formula drawn from the experience of ancient physicians by data mining techniques. Clinical study found that KHJX Decoction can significantly improve the overall clinical efficacy of chronic bronchitis with good clinical safety. Under the guidance of TCM herbal theory, object presented here is based on the work of KHJX Decoctionmining experience - clinical validation. The molecular docking method and receptor-ligand binding assay were applied to screen effective components from herbs of KHJX Decoction and the compatibility plan of effective components under the guidance of the principle of cold and heat effects compatibility. This study is of great significance to clarify the material basis and molecular mechanism of KHJX Decoction in the treatment of chronic bronchitis. It provides a new research mode for marine drug research.

Although the origin of Chinese medicine was well recorded inHuang-Di Nei-Jing, different opinions, however, now existed in the authenticity of discussions on five cardinal directions in theYi-Fa Fang-YiLun. From the perspective of regional systems, this paper began with the local culture of Chinese northern nomadic people, analyzed their fire using custom, moxibustion therapy, ice and snow culture and Shamanistic witchcraft. The purpose was to reveal that moxibustion therapy originated from Shamanistic witchcraft and medical practice of the northern nomadic people.

Calcium content and calcium-calmodulin complex were determined in endothelial cells before and after they were treated with endotoxin.It was found that endotoxin can promote the disintegration of calcium-calmodulin complex and greatly increase the cacium content in the endothelial cells.

Objective To make the surgical therapy of urethral stricture and occlusion more effective. Methods 154 patients treated in our hospital were included in this retrospective study,of these cases,40 cases were in anterior urethra and 114 in posterior part.Based on etiology,106 cases were from trauma,15 from infection and 33 from idiopathic causes.Open surgery was performed on 34 cases and endoscopic therapy on 120 cases. Results All of the anterior urethral cases were treated successfully,among them,18 cases were with open surgery and 22 with endoscopic surgery.Normal urination was achieved on the follow-up from 6 months to 12 months.Within posterior urethral stricture and occlusion situation,open surgery was in 16 cases with 10 cases of normal urination and endoscopic surgery in 98 cases with 92 cases of normal urination.6 cases with open surgery and 5 cases with endoscopy resulted in postoperative dysuria or anuria.Urethral stricture and occlusion were shown in all these unsuccessful operation according to our urethrogram. Conclusions Good result can be achieved by both open and endoscopic surgery in anterior urethral stricture.In case of posterior urethral condition,endoscopic procedure is the best choice.

Objective To investigate the factors influencing the diagnostic accuracy in CT-guided percutaneous transthoracic aspiration biopsy of lung lesions. Methods CT-guided percutaneous transthoracic biopsy was performed in 435 patients with surgical pathologic confirmation or clinical follow-up.Univariant statistical analysis and multivariant stepwise Logistic regression analysis were used to study the influence of lesion-related factors(benignancy or malignancy,size,location,depth,presence of cavity),procedure factors(laser-guidence,position of patient) and patient-related factors(sex,age,presence of emphysema);with the accuracy of the diagnosis. Results ① 289 lesions were diagnosed as malignant ones and 146 as benign ones.The accuracy of CT-guided biopsy was(83.4%)(363/435).Univariant analysis showed that the diagnostic accuracies for malignant and benign lesions were(88.9%)(257/289) and(72.6%)(106/146),respectively(?~2=(18.71),P=(0.00002)).Laser-group was superior to non-laser group((88.4%) versus(80.9%),respectively,?~2=(4.00),P=(0.0456)).Mean diameters of lesions in correct diagnostic group and non-correct diagnostic group were(3.78)?(1.64) cm and(3.02)?(1.26) cm,respectively((F=)(13.79),P=(0.0002)).②Multivariant stepwise Logistic regression analysis showed that among the various factors influencing the final benign or malignant diagnoses(Wald ?~2=(14.01),P=(0.0002)) and using laser-guidence(Wald ?~2=(3.92),P=(0.0477)) were significantly associated with the diagnostic accuracy. Conclusions Final correct diagnoses(benign,malignant) are closely related to the application of laser-guidence for determining the diagnostic accuracy in CT-guided transcutaneous thoracic needle aspiration biopsy.

Objective To evaluate the influence of lesion size and depth on the diagnostic accuracy and the rate of pneumothorax in patients undergone CT-guided transthoracic aspiration biopsy for pulmonary lesions.Methods CT-guided percutaneous transthoracic biopsy was performed in 398 patients that had surgical resection or clinical follow-up.According to lesion size,lesions were divided into≤2 cm,2～4 cm and ≥4 cm.Lesion depth was measured from the pleura surface to the edge of the lesion.This depth was classified in three categories:≤1 cm,1～3 cm and ≥3 cm.Comparison of the diagnostic accuracy and the frequency of pneumothorax in different size and depth of lesion was performed.Results(1)The overall diagnostic accuracy of CT-guided percutaneous needle aspiration biopsy was 83.2%(331/398).Pneumothorax occurred in 58(14.6%)of 398 biopsy;(2)The diagnostic accurate rate in different size of lesion was 73.3%(44/60),81.5%(176/216)and 91.0%(111/122)respectively,?2=9.91,P0.05.The occurred rate of pneumothorax in different depth lesion was 2.8%(4/141),14.8%(21/142)and 28.7%(33/115),?2=34.03,P

The appearance and changes of Acetylcholinesterase (ACHE) in the brains of 62 rats from early embryos to adults were studied by histochemical method and the brains of 19 rats of corresponding stages were examined with Nissl stain. The main results are as follows:1. AChE appeared in the following sequence: spinal cord, myelencephalon, metencephalon, mesencephalon, diencephalon and finally in telencephalon. In telencephaIon, AChE appeared earlier in paleocortex than in neocortex. The sequence described above showed that the appearance of AChE reflects cephalization of the nervous system in the rat.2. AChE-positive neurons of the rat brain consisted of cholinergic neurons and cholinoceptive ceils, both of which are related to the neurotransmitter ACh.3. The following nuclei of adult rat brain were shown to be AchE-positive in our specimens, but had not been reported in available literature: n. tractus mesencephali, n. anterior dorsalis thalami, n. anterior ventralis thalami, n. lateralis thalami, n. habenulae lateralis, n. reticularis thalami, n. supraopticus, n. paraventricularis, n. parafascicularis and n. ruber. In the cerebral cortex very few positive cells have been noticed.

Objective To investigate the dynamic changes of Trk(tropomyosin receptor kinase) and Akt(protein kinase B), and to explore the neuroprotective role and its mechanism of β-NGF (β-nerve growth factor) after focal cerebral ischemia. Methods A focal cerebral ischemia rat model was made and β-NGF was injected intra abdominally. The phosphorylation of Trk and Akt were tested by immunocytochemistry and Western blot assay. Results Trk receptor was increased obviously in the penumbra area after 8 h of infarction. The level of phosphorylated Trk(p-Trk) was increased after 2 h of infarction, while the level of phosphorylated Akt(p-Akt) had a decrease and then recovered gradually. The level of p Akt in cerebral ischemia group was decreased by 76.5% compared with that in control group after 8 h of infarction(P<0. 01). After the injection of β-NGF, the level of p-Trk was increased by 74.4% after 12 h of infarction(P<0.01), while the level of p-Akt was recovered significantly after 8 h of infarction, and had no statistical difference compared with the control group after 24 h of infarction (P>0.05). Conclusions Ischemia induces the activation and increased expression of Trk receptor, andβ-NGF may play a protective role in cerebral ischemia by increasing the phosphorylation of Trk and regulating the phosphorylation of Akt.

Objective To observe the prognosis 90 days after attack and the correlation among various risk factors in patients with transient ischemic attack (TIA). Methods The data of 90 days follow up and related risk factors of 61 patients clinically diagnosed with TIA were analyzed.We also compared the prognosis of those patients according to the change on diffusion weighted imaging (DWI). Results The incidence of various kinds of severe vascular events in 61 patients within 90 days was 16.4% (10/61). Among the patients with abnormal change on DWI, the incidence was 50% (8/16). However the incidence was 4.7% (2/43) in the patients with normal DWI. There was a statistical difference between the two groups (P
