China Pharmacy 2005;0(15):-
OBJECTIVE:To analyze the renal lesions induced by oral preparations of traditional Chinese medicines so as to provide theoretic basis for clinical rational drug use.METHODS:The CNKI full-text database between January 1991 and December 2008 were retrieved for clinical reports of renal lesions induced by oral preparations of traditional Chinese medicines.And the pertinent literature was sorted,analyzed and compared.RESULTS:176 reports(totaled 619 cases)were collected.Repeated long-term medication and overdosing etc were the major factors accountable for the renal lesion.CONCLUSION:Importance should be attached to the nephrotoxicity of oral preparations of traditional Chinese medicines,and which should be used rationally in the clinic and periodic examination of patients' renal function should be performed in taking oral preparations of traditional Chinese medicines.

Objective To summary indications and treatment results of operation and endovascular interventional therapy for intracranial aneurysms. Methods From 1992 to 2003 , 345 cases of intracranial aneurysms were reviewed .We putted attention to condition of patients and the size, shape and site of aneurysms particulary. Angiography was requested in all patients at different times. Results 236 patients undergo clipping operation . 31 patients appeared operation complications. 6 patients with postoperative hemorrhage recepted surgical operation again.9 cases died.3 patients were reoperated because of aneurysm clips translatory. 103 cases were embolized by microcoil.4 cases suffered transient aphasia after embolization, recovered after medical treatment. 1 patients died because of cerebral vessel spasm. 6 patients recepted medical treatment. Conclusions Operation is suitable for very small,gaint aneurysms which locate anterior circulation and indovascular interventional therapy for small, middle, big aneurysms. The result needs further long term follow-up study.

[Objective]For revealing the definition of the concept of the Yin of liver and the Yang of liver ,and its historical evolution. [Method]The definition of the concept of the Yin of liver and the Yang of liver and the mainstream view of Yin and Yang of before the Song Dynasty, Song Dynasty and modern is investigated in this paper. The definition of the concept of the Yin of liver and the Yang of liver of different periods, different ideological background and different mainstream view of Yin and Yang is clarified by historical investigation. [Result]Because of the influence of Confucius studies, there is not the definition of the concept of the Yin of liver and the Yang of liver based on the object of liver in the TCM theory of Han and Tang dynasties. The Yin of liver and the Yang of liver mainly refer to the yin qi and yang qi in the liver. Because of the influence of neo-confucianism, the concept of the Yin of liver and the Yang of liver based on the object of liver was established in the TCM theory of Song and Ming dynasties. The Yin of liver and the Yang of liver mainly refer to the body and function of liver. Under the background of modernization of TCM, the concept of the Yin of liver and the Yang of liver based on the object of liver was established in the basic theories of TCM. However, there is a controversy of the concept of the Yin of liver and the Yang of liver, because of the effect of modern philosophy and science, ignoring the change of Chinese philosophy. [Conclusion]The clear concept of the Yin of liver and the Yang of liver of different periods, different ideological background and different mainstream views of Yin and Yang will reduce the influence of the fictional historical. Whether in ancient literature research, the liver like zang-fu theory of TCM theory, research, or the modern liver zang-fu theory of TCM, and establishing the theory of Chinese medicine has a positive meaning.

Objective To study the diagnostic value of spectral CT in atypical tuberculosis ball and lung cancer.Methods 45 cases of pulmonary nodule or mass received unenhanced and two phase enhanced scan in gemstone spectral imaging mode,and all pulmonary nodule or mass were confirmed by pathology.Selecting unenhanced,arterial phase and venous phases of spectrum image,atypical tuberculosis ball group and lung cancer group were analyzed.Normalized iodine concentration (NIC), the spectral curve slope (λHU),CT value of unenhanced and two phase enhanced spectrum image were measured and calculated.Two independent samples t-test was used for the statistic analysis of each spectrum parameters between the two groups.The receiver operating characteristic (ROC) curve was obtained for comparing the sensitivity and specificity of each spectral parameter.Results Among the 45 patients,11 were atypical tuberculosis ball, and 34 were lung cancer.Comparison NIC,two phase enhanced λHU and the net enhanced CT values of 70 keV monoenergetic image of the two groups, lung cancer group was higher than atypical tuberculosis ball group,and the difference was statistically significant(P<0.05);However, the unenhanced CT value of 70 keV monoenergetic image of the two groups was not statistically significant (P>0.05).When the NIC diagnostic threshold was 0.105, the maximum Youden index (0.733), the area under the ROC curve was 0.89, and sensitivity and specificity was 82.4% and 90.9%, respectively.Conclusion The quantitative parameters of spectral CT is helpful in the diagnosis of atypical tuberculosis ball and lung cancer,especially the NIC with high value.

Objective To investigate effects of octreotide combined with aspirin on the growth and metastasis of gastric cancer in vivo. Methods SGC-7901, human gastric cancer cell line, was implanted orthotopically in the stomach of nude mice. Octreotide or aspirin alone and the combination of the two drugs were administrated for 8 weeks to investigate the effects of them on tumor growth and metastasis. Results At necropsy, xenografts in situ were found in all stomachs of nude mice except two nude mice in the combined group. The mean volume and weight of tumors in nude mice treated with octreotide or aspirin were significantly lower than those of control group. The inhibitory rate for tumors was 60.6% in octreotide group, 39.3% in aspirin group and 85.6% in the combined group with octreotide and aspirin respectively. The metastatic rates of gastric adenocarcinoma were markedly lower in any of treatment group than that in control group. No severe side action was observed in all of treatment group. Conclusion Octreotide combined with aspirin greatly enhanced the anti-growth effect on gastric cancer in vivo when compared to using either of them and inhibited the metastasis of gastric adenocarcinoma in nude mice.

Objective To study the changes of imaging features of rats with implanted liver cancer before and after electrochemotherapy (EChT).Methods Immediate cancerous ascites injection method was used to form rats liver cancer model. The imaging features of rats with implanted liver cancer, including tumor size, density, border, enhancement and singal were observed with CT and MRI respectively. Results The characteristic magings showed all these rats bearing single, round tumor in liver seven days later. Low density lesions were seen in pre contrast scans and tumor border intensification were seen on contrast scans. Low signal lesions were found in MRI T 1WI and high signal lesions were revealed on MRI T 2WI. Seven days after EchT, low density lesions were seen in pre contrast scan and non enhanced appearences were seen in contrast scan by CT. High signal and mixed signal lesion were seen in MRI T 1WI and relative low signal lesion were seen in MRI T 2WI.Conclusions Imaging features analysis is useful to assess the therapeutic effect on rats with implanted liver cancer before and after EChT.

Objective To compare the effects of electrochemotherapy (EChT) on implanted liver tumor cells apoptosis of rats.Methods Immediate cancerous ascitis injection method was used for the formation of rats liver tumor model and then followed by rats liver tumor treatment with EChT. Tumor size, necrosis and apoptosis indexes were observed after one week by imaging or pathologic method. The results were compared with those of control group. Results Before EChT, rats liver tumor volume appeared as (100?6)mm 3 and turned to be (125?10)mm 3 one week after EChT, which were significantly smaller than those of the control group [(190?11)mm 3], P
