Objective To study the effect of three kinds of reagent: ethrel, Aspirin, tryptophan on the accumulation of medicinal component in Catharanthus roseus leaves. Methods To treat these potplants of C. roseus in green house with the three reagents in different concentrations, respectively. Then, two days later, the contents of catharanthine and vinblastine in leaves were determined by RP-HPLC. Results The three reagents can obviously improve the accumulation of indole alkaloids, including catharanthine and vinblastine in C. roseus leaves. Their optimum treatment concentration was finally comfirmed. Conclusion These three kinds of reagent apparently promote the accumulation of total indole alkoloids in the leaves of C. roseus.

Objective To evaluate the value of CT guided percutaneous lumbar diskectomy (CT PLD) at plateau area. Methods Sixty eight cases of lumbar disc herniation was reated with CT PLD. (1)Before operation, diseased intervertebral disc was scanned, cases were selected, and operation plan was plotted . (2)The best puncture arrangement was chosen on the current video CT picture by designing the puncture path, noting down the puncture parameter, and marking the puncture spot on patient′s body surface. (3)Puncture was performed according to fixed parameter. (4)Operation was performed after the puncture needle was put into the disc ascertained by scan.(5)CT scan was done again after operation to observe if the puncture path had bleeding and intervertebral disc recovery. Results After 3 to 18 months′ follow up, 28 cases were prominent effective and 36 cases effective. The lumbar disc backed 1 to 4 mm. The total effective rate was 94.12%. Conclusion CT PLD is an ideal therapeutic method for lumbar disc herniation at plateau area because it is safe and effective and with less complications.

Objective To improve the 2,3,5-triphenyl tetrazolium chloride (TTC) solution method for measuring the viability of Cistanche deserticola seeds and investigate the change in viability during storage at 5 ℃. Methods The effect of the testa,TTC concentration,sodium hypochlorite concentration (NaClO),and staining time were studied,and seed viability during storage at 5 ℃ was measured with the improved method. Results Seeds were kept for 48 h in 0.5% TTC solution at 40 ℃,and then for 2 h in 0.2% NaClO solution;Seed viability was measured under a stereomicroscope. Storing seeds of C. deserticola for 1 to 2 years at 5 ℃ had no significant effects on their viability. However,the percentage of seeds with high viability was increased with the extension of the storage time at 5 ℃. Conclusion A convenient and rapid method for measuring the viability of C. deserticola seeds is developed. Storing C. deserticola seeds at 5 ℃ could improve their viability

Objective To explore the value of CT diagnosis of high altitude pulmonary edema (HAPE). Methods The CT findings in 16 patients unfit to high altitude were analyzed. Results The findings on CT were as follows: (1) The early stage of HAPE showed ground glass opacity, most of which located at the superior segment and posterior basis segment of inferior lobes, with the right lung to occur earlier than that of the left lung. (2)The advanced stage showed shaggy opacity. (3) The late stage lesions developed to posterior and apical segment of the superior lobes, air bronchus sign could be seen on involved segments. (4)Right lung was more serious than left lung. Conclusion CT was an ideal method to find HAPE. The accuracy of CT diagnosis in HAPE was 100%.

OBJECTIVESTo increase the diagnosis and treatment of ectopic ACTH syndrome.

METHODSThe data of 12 ectopic ACTH syndrome patients treated from 1985 to 1999 were retrospectively analyzed.

RESULTSTwelve patients were diagnosed as having ACTH syndrome by endocrinary test and primary tumors were ascertained by imaging examination. Follow-up from 7 months to 8 years showed 3 out of 5 patients with radical resection of primary tumor died. One patient with bilateral adrenorectomy was still alive. All patients received only chemotherapy except one died.

CONCLUSIONSPatients with Cushing's syndrome should be evaluated by endocrine test and followed up by imaging screen examination. The key points to increase treatment effect include early detection, localization and resection of primary tumors.

Objective To explore the prescribing law of TCM in national patents for the treatment of benign prostatic hyperplasia(BPH);To provide a reference for clinical medication.Methods Data on TCM compound prescriptions for the treatment of BPH were retrieved from the China National Intellectual Property Administration(CNIPA)patent retrieval and analysis system,covering the period from January 1,2000,to October 31,2023.The frequency,efficacy category,properties and tastes,meridian tropism,core complex co-occurrence network,and potential TCM clusters mentioned in the patents were analyzed using Excel 2016,SPSS Modeler 18.0,SPSS Statistics 27,and Cytoscape 3.10.0 software.Results A total of 182 patents were included,involving 404 kinds of Chinese materia medica,with a total frequency of 2054 times.Among them,22 kinds of Chinese materia medica had a frequency of≥20,with the most frequently used Chinese materia medica being Astragali Radix,Glycyrrhizae Radix et Rhizoma,Phellodendri Chinensis Cortex,Epimedii Folium,Salviea Miltiorrhizae Radix et Rhizoma,Plantaginis Semen,Poria,Vaccariae Semen,Alismatis Rhizoma and Paeoniae Radix Rubra.The high-frequency herbs primarily consisted of tonifying herbs(267 times,13.00%),blood circulation-activating and stasis-resolving herbs(216 times,10.52%),and diuretic and dampness-percolating herbs(147 times,7.16%).The properties of the herbs were mainly sweet and cold,and they were mainly attributed to the liver and kidney meridians.Association rule analysis yielded 10 common drug pairs,including Cornus Officinalis-Rehmannize Radix et Praeparata,Curcumae Rhizoma-Sparganii Rhizoma,and Astragali Radix-Codonopsis Radix.The drug combination with the highest confidence was Angelicae Sinensis Radix-Phellodendri Chinensis Cortex-Glycyrrhizae Radix et Rhizoma.Clustering analysis revealed five drug combinations,while potential TCM clustering analysis identified five groups,among which the"Zingiberis Rhizoma-Os Draconis-Angelicae Pubescentis Radix-Scallion-Rice Bran-Speranskiae Herba"network demonstrated the highest degree of interconnection(Score=6).Conclusion The high-frequency herbs in national patents for the treatment of BPH with TCM compound prescriptions mainly focus on tonifying the spleen and kidney,activating blood circulation to remove stasis,and clearing heat and draining dampness,providing a reference for clinical practice.

The prevalence of dilated cardiomyopathy （DCM） has been increasing year by year，which seriously endangers the physical and mental health of patients. Establishing an animal model that conforms to the clinical characteristics of the disease is a prerequisite for conducting experimental research on DCM. This study sorted out and summarized the commonly used DCM animal models and evaluated the degree of consistency between the models and clinical practice based on the etiology and pathogenesis of traditional Chinese and western medicine and clinical diagnostic criteria. The models with high consistency with western medicine include immune models，drug toxicity models，and tachycardia models，while the models with high consistency with traditional Chinese medicine include drug toxicity models，gene correlation models，and tachycardia models. With consideration of the characteristics of the symptoms，consistency，and their respective advantages and disadvantages，the more ideal models are drug toxicity models，tachycardia models，and gene correlation models. In addition to evaluating the clinical consistency of traditional Chinese and western medicine in DCM animal models，this study also analyzed the advantages and disadvantages of existing DCM animal models，existing problems，and observation indicators of the models and pointed out the lack of standardized and unified syndrome model differentiation standards. Due to the complexity of the disease and the unclear pathogenesis，there are few studies on DCM models，and there is room for improvement. On this basis，four improvement directions are proposed to make the animal models as close to the clinical pathological and physiological processes as possible，so that the combination of disease and syndrome in animal models is more practical. These animal models can provide an experimental basis for the pathogenesis，drug intervention，efficacy evaluation，and scientific research of DCM and better serve scientific research and clinical practice.
