Journal of Traditional Chinese Medicine 1993;0(02):-
Objective To observe the relation between functions of vessels of lower extremities and TCM syndromes differentiation in diabetes patients. Methods Totally 168 diabetics of Type II were differentiated into 5 syndromes, i.e. 29 cases of yin deficiency with excessive heat, 41 cases of qi and yin deficiency, 30 cases of yin and yang deficiency, 37 cases of blood stasis in channels, and 31 cases of damp heat affecting the spleen, and 26 healthy people were involved in the control group. The peripheral vessel diagnostic system was adopted to get the toe photoplethysmogram (PPG) and ankle brachial index (ABI) to observe the blood perfusion of limb terminals and the functional state of lower limb arteries. The relation between function of vessels of lower extremities and TCM syndrome was analyzed. Results All the diabetic groups were related with the arterial blood supply of toe terminals. Diabetes was the main risk factor in affecting the terminal blood supply (P

A variety of extra-cellular signals could activate the target molecules and induce the associated biological effects depended on different signal pathways. Apoptosis, or programmed cell death, is a conservation process essential for normal development and homeostasis of biologist. It's known that a number of factors and pathways can lead to apoptosis. Specific phosphorlipids and proteins of biomembrane could activate the signal cascades of apoptosis. The interaction of caspases, bcl-2 family and mitochondria play an essential role in regulation of apoptosis.

Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P >0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)%,(7.54 ± 0.97)% vs.(4.80 ± 0.54)% ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P < 0.05).But the difference between PVD group and DM group had no statistical significance (P > 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P < 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P< 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P < 0.05),CRP was negatively correlated with ABI (r =-0.529,P < 0.05),and Hcy was positively correlated with CRP (r =0.528,P < 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P < 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P < 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.
METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).
RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).
CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

Objective To investigate the protective effects of propofol against acute lung injury(ALI) induced by oleic acid.Methods Forty adult male SD rats weighing 250-290 g were anesthetized with intraperitoneal(i.p.)20% urethrane 6 ml?kg~(-1) and tracheostomized.Left common carotid artery and right internal jugular vein were cannulated for BP monitoring and fluid and drug administration.The animals were randomly divided into 5 groups (n=8 each):Ⅰ control group;Ⅱ ALI group in which ALI was induced by oleic acid 250 mg?kg~(-1) i.v.;Ⅲ,Ⅳ and Ⅴ ALI+propofol group in which propofol was continuously infused i.v.at 4, 8 and 16 mg?kg~(-1)?h~(-1) for 4 h immediately after i.v.oleic acid.The animals were killed at 4 h after oleic acid administration.The lungs were immediately removed for(1)examination of ultrastructure of the lung with transmission electron microseope and(2)determination of SOD and MPO activity,content of MDA,level of IL-10 and IL-18 and expression of NF-kB in lung tissue.Results In group Ⅱ intravenous oleic acid produced damage to mitochondria,rough endoplasmic reticulum and osmiophilic multi-lamellar body in type Ⅱ alveolar epithelial cells. Propofol infusion in group Ⅲ,Ⅳ and Ⅴ attenuated the damage to different degrees.In group Ⅱi.v.oleic acid produced significant decrease in MPO and SOD activity and significant increase in MDA content,IL-10,IL-18 and NF-kB expression in lung tissue.Intravenous propofol infusion attenuated the decrease in MPO and SOD activity, increase in IL-18 expression and MDA content and NF-kB expression in lung tissue produced by i.v.oleic acid, but increased IL-10 expression in lung tissue further.The best protective effect was seen in group Ⅳ.Conclusion Propofol i.v.infusion at 4-16 mg?kg~(-1),h~(-1) can inhibit the oxidative response and inflammatory response and down-regulate NF-kB expression in lung tissue.Propofol infusion at 8 mg?kg~(-1)?h~(-1) provides best protective effects.

·AIM: Impairment of choroidal perfusion was found in AMD patients. We postulated that vasoactive agents,which can reduce choroidal blood flow resistance, might prevent the development of choroidal neovascularization (CNV). D-Timolol and L-Timolol are hypotensive agents used in cardiovascular and glaucoma therapy. Their effects on laser-induced experimental CNV rat model and human umbilical vein endothelial cells (HUVEC) were thus evaluated.·METHODS: Male Brown Norway rats were anesthetized to receive Nd:YAG laser to break the Bruch's membrane. D-Timolol and L-Timolol were given once daily through intraperitoneal injection after laser treatment for 4wk. Fluorescein angiography was performed on 2wk and 4wk. HUVEC were tested by proliferation assay and adhesion assay with D-Timolol and L-Timolol at different concentrations.· RESULTS: D-Timolol reduced the fluorescein leakage to 83% of the control group in laser-induced rat's CNV model at a dosage of 15mg/(kg·d). L-Timolol had no effect on CNV formation even at a higher dosage of 20mg/(kg·d). D-Timolol inhibited the endothelial cells proliferation significantly by 300mg/L. L-Timolol also significantly inhibited the cell proliferation at 1 000mg/L. But at a lower dose such as 300mg/L, no significant inhibitory effect was found. Both drugs showed no effect on cell adhesion function in cell culture experiments.· CONCLUSION: D-Timolol was found to prevent CNV development in laser-induced model in vivo and inhibit vascular endothelial cells proliferation in vitro. L-Timolol had no effect on cell proliferation at the same dose, and neither on rat CNV model. The results indicate these two isomers have different functions on rat's CNV prevention and on HUVEC cell proliferation.
