Clinical Efficacy of Tiandan Tongluo Capsule Against Cerebral Infarction in Convalescence Corresponding to Stoke Due to Wind-Phlegm-Static Blood Obstructing Vessels / 中国实验方剂学杂志

Objective:To evaluate the safety and effectiveness of Tiandan Tongluo capsule in the treatment of cerebral infarction （CI） in convalescence （stoke involving meridians and collaterals due to wind-phlegm-static blood obstructing vessels）， with Naoshuantong capsule as a control. Method:A total of 352 convalescent patients with CI differentiated into stoke involving meridians and collaterals due to wind-phlegm-static blood obstructing vessels in traditional Chinese medicine （TCM） were included in this multi-center， randomized， double-blind， single-simulated， Naoshuantong capsule-controlled clinical trial， which lasted from 28 December， 2016 to 12 April， 2019. After being randomized into an experimental group and a control group at a ratio of 3∶1， patients in the experimental group were provided with oral Tiandan Tongluo capsule， five capsules per time， three times per day， whereas those in the control group received both Naoshuantong capsule simulator， two capsules per time， three times per day， and Naoshuantong capsule， three capsules per time， three times per day， for 12 successive weeks. The patients were followed up until 180 days after onset. The Barthel activities of daily living （ADL） index （BI） score was used as the primary outcome， and the secondary outcomes included neurological deficit score ［assessed with National Institutes of Health Stroke Scale （NIHSS）］， modified Rankin scale （mRS）， TCM syndrome score， and proportion of patients with new vascular events. The changes in laboratory indexes and the incidence of adverse reactions during treatment were observed. Result:Among the 389 cases enrolled， 30 dropped out， with the drop-out rate being 7.71%. There were 374 cases included in the full analysis set and 377 in the safety set. The comparison with the control group revealed that the total BI score and the percentage of BI score ≥ 75 in the experimental group were increased， but the difference was not statistically significant. The percentage of mRS score ≤ 2 within 180 days after onset in the experimental group obviously elevated in contrast to that of the control group （<italic>P</italic><0.05）. As demonstrated by TCM syndrome score analysis， the markedly effective rate in the experimental group was significantly higher than that in the control group （<italic>P</italic><0.05）. During the trial， the incidence rates of new vascular events in the experimental group and the control group were 0.00% and 1.09% （one case）， respectively， exhibiting no statistically significant difference between the two groups. Conclusion:Tiandan Tongluo capsule and Naoshuantong capsule both produce definite therapeutic effects in the treatment of CI in convalescence （stoke involving meridians and collaterals due to wind-phlegm-static blood obstructing vessels）. Compared with Naoshuantong capsule， Tiandan Tongluo capsule better alleviates neurological deficit， promotes neural functional recovery， and improves TCM syndrome score， without inducing severe adverse reactions.

Effect of Danggui Shaoyaosan on Diminished Ovarian Reserve in Model Rats： An Exploration Based on TGF-β1/ Smads Signaling Pathway / 中国实验方剂学杂志

Objective:To observe the improving effect of Danggui Shaoyaosan on diminished ovarian reserve （DOR） in rats triggered by Tripterygia wilfordii polyglycoside tablet combined with stress， and to explore the role of transforming growth factor-<italic>β</italic>₁（TGF-<italic>β</italic>₁）/Smads signaling pathway in such improvement. Method:Forty-eight female SD rats with normal sexual cycle were selected and randomly divided into a normal group （<italic>n</italic>=8） and a modeling group （<italic>n</italic>=40）， and the ones in the modeling group were given Tripterygium wilfordii polyglycoside tablets （50 mg·kg^-1） combined with random stress for 15 d. After successful modeling， the rats were randomized into the model group， low-， medium-， and high-dose （3.96， 7.92， 15.84 g·kg^-1） Danggui Shaoyaosan groups， and estradiol valerate group （0.09 mg·kg^-1）， with eight in each group. Under the premise of stress exposure， they were separately gavaged with the normal saline， low-， medium- and high-dose Danggui Shaoyaosan， and estradiol valerate for 15 successive days. The estrous cycle of rats in each group was observed daily. After intervention， the rats were sacrificed and the ovarian visceral index was calculated. The pathological changes in ovarian tissues were observed by hematoxylin eosin （HE） staining. The protein expression levels of TGF-<italic>β</italic>₁ and TGF-<italic>β</italic>₁receptor （TGF-<italic>β</italic>₁R） in the ovarian tissues of rats were measured by immunohistochemistry （IHC）， and the mRNA expression levels of Smad2， Smad3， and Smad7 in the ovarian tissues by real-time polymerase chain reaction （Real-time PCR）. Result:Compared with the normal group， the model group exhibited disordered estrus cycle （<italic>P</italic><0.05）， reduced visceral index （<italic>P</italic><0.01）， and down-regulated TGF-<italic>β</italic>₁ and TGF-<italic>β</italic>₁R protein and Smad2 and Smad3 mRNA expression in the ovarian tissues （<italic>P</italic><0.01）， and up-regulated Smad7 mRNA expression （<italic>P</italic><0.01）. Compared with the model group， Danggui Shaoyaosan at the low， medium， and high doses and estradiol valerate improved the estrus cycle of rats to varying degrees （<italic>P</italic><0.05） and increased the visceral index， with better effects observed in the medium-group and high-dose Danggui Shaoyaosan groups （<italic>P</italic><0.05，<italic>P</italic><0.01）. Besides， the protein expression levels of TGF-<italic>β</italic>₁ and TGF-<italic>β</italic>₁R and the mRNA expression levels of Smad2 and Smad3 in the ovarian tissues were elevated to varying degrees （<italic>P</italic><0.01）， and the Smad7 mRNA expression declined （<italic>P</italic><0.01）. The improvements in TGF-<italic>β</italic>₁ and TGF-<italic>β</italic>₁R protein expression of the medium-dose Danggui Shaoyaosan group and estradiol valerate group were more obvious. Conclusion:Danggui Shaoyaosan significantly improves ovarian reserve in DOR rats， which is closely related to the regulation of TGF-<italic>β</italic>₁/Smads signaling pathway.

Clinical observation on diabetic peripheral neuropathy treated with electroacupuncture and acupoint injection / 中国针灸

<p><b>OBJECTIVE</b>To compare the differences in the therapeutic effect on diabetic peripheral neuropathy between the combined therapy of electroacupuncture and acupoint injection and the simple acupoint injection.</p><p><b>METHODS</b>Under the satisfactory control of blood glucose, 60 cases of diabetic peripheral neuropathy were divided randomly into two groups, 30 cases in each one. In electroacupuncture plus acupoint injection group (group A), electroacupuncture and acupoint injection with Methylcobalamin were administered. Penetrating acupuncture was applied from Gongsun (SP 4) to Quanzhong (Extra) and from Yongquan (KI 1) to Taichong (LR 3) mainly. Acupoint injection was administered on Sanyinjiao (SP 6). In acupoint injection group (group B), only acupoint injection with Methylcobalamin was provided on Sanyinjiao (SP 6). After 2 sessions of treatment, the conduction velocity of ulnar nerve and tibial nerve was measured. The scores of Chinese medicine syndrome and diabetic peripheral neuropathy were recorded before and after treatment in two groups.</p><p><b>RESULTS</b>The effective rates were 90.0% (27/30) and 63.3% (19/30) in group A and group B respectively, presenting significant statistical difference (P < 0.05). After treatment, the motor nerve conduction velocity (MCV) and sensory nerve conduction velocity (SCV) of ulnar nerve and tibial nerve in group A were higher than those in group B (P < 0.05, P < 0.01). After treatment, the score of Chinese medicine syndrome in group A was lower than that in group B (14.36 +/- 1.88 vs 26.58 +/- 3.52, P < 0.01), the score of diabetic peripheral neuropathy in group A was lower than that in group B (12.86 +/- 4.28 vs 17.89 +/- 4.35, P < 0.01).</p><p><b>CONCLUSION</b>Electroacupuncture and acupoint injection with Methylcobalamin achieve a significant clinical efficacy on diabetic neuropathy and its efficacy is superior to that of simple acupoint injection with Methylcobalamin.

Alteration of the Cell Cycle during the Differentiation of HL-60 Cells by Induction of Retinoic Acid / 中国实验血液学杂志

To study the alteration of the cell cycle during the differentiation of human myeloid leukemia cell line HL-60 induced with all trans-retinoic acid (RA), the flow cytometry was used to assay the various phases of cell cycle in HL-60 cells treated with RA. The results showed: (1) S + G(2)/M phase proportion kept relative invariability during the 48 hours incubation of HL-60 cells with RA, however, the proportion alteration of S-phase cells was associated with the RA concentrations. At 10(-6) mol/L RA, the proportion of S-phase cells appeared a temporarily increasing peak followed by persistent decrease of S-phase proportion. At 10(-5) mol/L RA, S-phase cell proportion only appeared the persistent decreasing tendency. (2) Re-culture of HL-60 cells without RA showed the decrease of S + G(2)/M and S-phase cells was associated with the increase of differentiated cells, but not all HL-60 cells were triggered into differentiation at the same time. Once the cells start to differentiate, even if there is no RA presence, the HL-60 cells were still differentiated until maturation. In conclusion, HL-60 cells are able to differentate and maturate after exposure to RA for a period of time. S-phase proportion is related to the concentrations of RA. Once the cells start to differentiate, even if there is no RA presence, the HL-60 cells still differentiatiated until maturation.
