Journal of Integrative Medicine 2008;6(5):498-501
OBJECTIVE: To explore the material foundation of kidney-yang-deficiency syndrome. METHODS: Two kinds of rat models of deficiency of kidney-yang were induced by adenine intragastric administration (model I) and hydrocortisone intramuscular injection (model II). One hundred rats were randomly divided into normal control group, model I group, low-dose model II group, medium-dose model II group and high-dose model II group. After model establishment, contents of serum creatinine (SCr), blood urea nitrogen (BUN), and urine creatinine (UCr) were detected by automatic biochemistry analyzer; freezing point method was used for 24-hour urinary osmotic pressure (Uosm) testing and kaolinite method was used to detect the content of urinary 17-hydroxycorticosteroid (17-OHCS). Expression of aquaporin-1 in renal tissue was observed by using real time reverse transcription polymerase chain reaction. RESULTS: The rats of model groups had the characteristics of kidney-yang deficiency syndrome. The contents of SCr and BUN were significantly higher in model I group than in normal control group and three model II groups (P<0.05), and UCr and Uosm were significantly lower (P<0.05). The level of urinary 17-OHCS and expression of aquaporin-1 in renal tissue were decreased in the model I group (P<0.05) as compared with the normal control group. Compared with the normal control group, the content of SCr was increased and urinary 17-OHCS was decreased in the medium-dose model II group, but the expression of aquaporin-1 was increased in three model II groups with a dose-dependent manner. CONCLUSION: Aquaporin-1 may be one of the material foundations of kidney-yang-deficiency syndrome.
3.Stratified therapeutic choices in elderly patients with diffuse large B-cell lymphoma
Journal of International Oncology 2021;48(5):317-320
The prognosis of elderly (>60 years) patients with diffuse large B-cell lymphoma (DLBCL) is significantly worse compared with young patients, and there is currently no standard treatment. Elderly patients with DLBCL are highly heterogeneous, a stratification before treatment can help achieve precise medicine and improve outcome of them. R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin and prednisolone) is still the recommended treatment for fit elderly DLBCL patients; and for unfit or very old patients, chemotherapy of reduced dose or palliative treatments should be considered. Choices for relapsed or refractory patients are limited, and novel compounds or therapies that are well tolerated may have a good application prospect.
4.High-protein diet and high-grade proteinuria aggravate the progression of chronic renal failure in rats
Journal of Integrative Medicine 2007;5(3):333-7
OBJECTIVE: To study the effects of high-protein diet (HPD) and high-grade proteinuria in aggravating the progression of chronic renal failure (CRF) in rats. METHODS: CRF with high-grade proteinuria was induced by supplying HPD in five sixth nephrectomy rats, and the changes of serum creatinine (Scr), blood urea nitrogen (BUN), endothelin-1 (ET-1), thromboxane B(2) (TXB(2)) and 6-keto-prostaglandin F(l alpha) (6-Keto-PGF(l alpha)) were observed. At the same time, the content of malondialdehyde (MDA), and the activities of glutathione peroxidase (GSH-Px) and superoxide dismutase(SOD)were measured in blood and renal tissue of the rats. RESULT: HPD and high-grade proteinuria could accelerate the damage of kidney through increasing the levels of ET-1 and TXB(2), reducing the level of 6-Keto-PGF(l alpha), and attenuating the activities of SOD and GSH-Px. CONCLUSION: HPD can accelerate the damage of kidney through inducing the high-grade proteinuria in five sixth nephrectomy rats, influencing the expression of kidney vasoactive substance, and reducing the anti-oxidation.

The study is to investigate the relationship between dyslipidemia and impaired glucose tolerance (IGT). Ninety elderly nondiabetic patients (60 -84 years old) were under long-term follow-up in outpatient department. Blood lipid measurement and oral glucose tolerance test (OGTr) were performed,the two-hour glucose levels (2 hPBG) between normal and abnormal blood lipid groups were compared. We found that patients with hypertriglyceridemia had a significantly higher 2 hPBG than patients with normal blood triglyceride(P<0. 01 ). But there were no differences in 2 hPBG levels between other dyslipidemias and normal lipid patients. OGTT screening in elderly patients with hypertriglyceridemia can be helpful in early detection and prevention of diabetes.

There lack scientific methods for evaluating the treatment of cancer pain with external therapies of traditional Chinese medicine (TCM). The level of clinical study in this field needs to be improved. The authors assert that when external therapies of TCM are applied to treat cancer pain, different types of cancer pain should be distinguished and treatment should be applied according to such a differentiation. Under this framework scientific evaluation can be conducted. The authors also assert that the findings of randomized, blinded and controlled trials should be given particular attention, and it is necessary to include titration of morphine into clinical trails of external therapies for the treatment of cancer pain, not only complying with the three-ladder principle for treating cancer pain suggested by the World Health Organization, but also not influencing the effect evaluation of external therapies of TCM on cancer pain. Patient diaries recording pain were revised as observation indexes. The primary indicator of efficacy was the pain intensity score and the secondary indicators were the equivalent of morphine and the remission rate of pain. The time to onset, remission duration and comparison of assessment of pain influence can mirror the characteristics of external therapies of TCM on cancer pain.
