OBJECTIVETo compare the efficacy between moving cupping at Hechelu combined with rubbing method and western medication for depression of diabetes mellitus (DM).
METHODSTwo hundred and sixteen patients were randomly divided into an observation group and a control group, 108 cases in each group. Patients in the observation group were treated with moving cupping at Hechelu combined with rubbing method, once every: other day; six treatments were considered as one course, and totally two courses were given with an interval of: 4 days between courses. Patients in the control group were treated with oral administration of fluoxetine hydrochloride capsules, once a day for consecutive 4 weeks. The Hamilton depression scale (HAMD), self-rating depression scale (SDS) and TCM symptom score were measured before treatment, after the treatment and in follow-up visit one and a half months after treatment. The fasting blood glucose was tested before and after treatment. The glycosylated hemoglobin (HbA1c) was tested in the follow-up visit.
RESULTSThe total effective rate was 90.9% (90/99) in the observation group, which was superior to 73.7% (70/95) in the control group (P < 0.05). After the treatment, HAMD, SDS and TCM symptom scores were all reduced apparently in the observation group and the control group (all P < 0.05). After the treatment and the follow-up visit, the TCM symptom score in the observation group was lower than that in the control group (P < 0.05). The levels of HbA1c and GLU were stable in the observation group, and were decreased compared with those before treatment; but the difference between the, two groups was not significant (P > 0.05).
CONCLUSIONThe Hechelu theory-based TCM treatment has better: efficacy for depression of diabetes mellitus than fluoxetine hydrochloride capsule, which has less adverse effects.

Aim To study the mechanisms of inotropic responses to doxazosin enantiomers in the isolated rat atrium.Methods We analyzed the positive inotropic response to (-)doxazosin and the negative inotropic response to (+)doxazosin in the left atrium of rat u-sing receptor-pharmacological technique.Results In the preparation treated with verapamil,the positive in-otropic responses to 3 μmol·L-1 (-)doxazosin were significantly inhibited from the control level (245.7 1 ± 44.29)mg to (172.50 ±43.34)mg,(P<0.05).In the preparation treated with methylene blue,the posi-tive inotropic responses to 3 μmol·L-1 (-)doxazosin were significantly potentiated from the control level (245.7 1 ±44.29 )mg to (303.33 ±45 .90 )mg,(P<0.05 ).In the preparation treated with H-89 ,the positive inotropic responses to 3,10 and 30 μmol · L-1 (-)doxazosin were (338.57 ±96.86 ) mg, (471.43 ±107.61)mg and (520.00 ±103.44)mg, which were significantly (P<0.05 ~0.01)larger than the control levels of (245.71 ±44.29)mg,(314.29 ±90.34)mg and (357.14 ±68.49 )mg.Treatment with phenoxybenzamine,atropine,propranolol or indo-methacin did not significantly affect the responses to doxazosin enantiomers.Conclusion The positive ino-tropic responses to (-)doxazosin in the isolated left a-trium of rat are partially involved in L-type Ca2+chan-nels and intracellular cGMP level.However,α-adre-noceptors,muscarinic receptors,β-adrenoceptors and cyclooxygenases are not related to the responses to doxazosin enantiomers.

Objective To study the effect of serotonergic efferent projection of the dorsal rophe nucleus (DRN) on the activity of substantia nigro pars compacta (SNc) and ventral tegmenta area (VTA) dopaminergic neurons after lesioning of the DRN by the neurotoxin 5,7-drhydroxytryptamine (5,7-DHT) in rot. Methods The changes in the firing rote and firing pattern of SNc and VTA dopaminergic neurons were observed with extrocellular recording in control and the lesioned rats. Results The results showed that the mean firing rotes of the fast-firing dopaminergic neurons of the SNc in control and the lesioned rots were (5.34±0. 13 ) Hz (n = 23 ) and ( 7.13±0. 49 ) Hz (n=37), respectively. The mean firing rote of the fast-firing dopaminergic neurons of the SNc in the lesioned rats was significantly increased when compared to that of control rots (P<0.01), while the mean firing rote of the slow-firing dopaminergic neurons of the SNc did not change. The mean firing rotes of dopaminergic neurons of the VTA in control and the lesioned rots were (5.27±0. 38)Hz (n=35) and (3.6±0.2)Hz (n=52), respectively. Lesioning of the DRN induced a significant decrease in the mean firing rote of dopaminergic neurons of the VTA. The firing pattern of SNc and VTA dopaminergic neurons changed towards a more bursting or irrgular firing after the lesioning. Conlusion These data suggest that the serotonergic efferent projections of the DRN significantly affect the activity of SNe and VTA dopaminergic neurons.

Objective To study the changes in neuronal activity of the zone incerta (ZI) following the unilateral lesion of the nigrostriatal pathway. Methods Eiectrophysiological recordings of ZI neurons were made in normal rats and in two groups of rats at different time intervals after injection of 6-hydrodopamine (6-OHDA) into the pars compacta of snbstantia nigra by extracellular recording in vivo. Results The results showed a significant increase in the mean firing rate of ZI during the second and fourth weeks after 6-OHDA lesion [-n=32, (3.6±2. 2)Hz, P<0.001; n=35, (9.3±6.6)Hz, P<0. 001, respectively] compared to that of normal rats [n=39, (9.2±5.2)Hz]. However, no significant change was observed between two groups of 6-OHDA-lesioned rats. With regard to firing pattern, 7.7%(3/39) of ZI neurons discharged regularly, 82.1% (32/39) irregularly and 10. 3% (4/39) in bursts in normal rats. During the second week after 6-OHDA lesion, the regular, irregular and bursting firing neurons recorded in the ZI were 9.4% (3/32), 59. 4% (19/32) and 31.3% (10/32), and during fourth week, the regular, irregular and bursting firing neurons were 14.3% (5/35), 57.1% (20/35) and 28. 6% (10/35), respectively. The firing pattern of the neurons in the three different groups did not change significantly. Conclusion These results suggest that the firing rate of ZI neurons in 6-OHDA-lesioned rats is increased significantly, which may contribute to the pathophysiology of Parkinson's disease.

High mobility group A2 protein (HMGA2), an architectural factor, is highly expressed in various cancer types including lung cancers. It is a candidate target for cancer therapy. RNAi is an effective gene silencing method with low cost and less time-consuming. It is possible to exploit this technology in therapy. Here, 5 siRNAs targeting Hmga2 gene (HMGA2 siRNA1-5) were designed and synthesized. MTT assay, colony formation assay, transwell assay and flow cytometry were used to evaluate the effects of these siRNAs on lung cancer cell lines (NCI-H446 and A549). Results from cell proliferation, clone formation, migration and apoptosis showed that HMGA2 siRNA1, 3, 5 could affect these aspects for both lung cancer cell lines. Among the five siRNAs, HMGA2 siRNA5 showed the greatest inhibition effects. The inhibition effects of HMGA2 siRNA5 are sequence specific and are not due to the induction of interferon response. Taken together, siRNAs targeting Hmga2 gene are potential candidates for lung cancer gene therapy.

OBJECTIVETo detect the influence of compatibility of rhubarb with different traditional Chinese medicines (TCM) on extracted quantities of AQs, and to provide scientific basis for the clinical code for rhubarb preparation.
METHODThe influence of compatibility of rhubarb with different traditional Chinese medicines (saponin, alkaloids, flavonoids TCMs, animal medicines and mineral medicines) on decocting volume of anthraquinone substance was detected using ultra performance liquid chromatography.
RESULTIn comparable conditions, more AQs were extracted from mixed decoction of rhubarb and saponin medicinal materials (Astragali Radix, Notoginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, Polygalae Radix, Ginseng Radix et Rhizoma) than single decocting of rhubarb. The mixed decoction of rhubarb and alkaloid medicinal materials (Coptidis Rhizoma, Sophorae Flavescentis Radix, Prepared Aconiti Lateralis Radix Praeparata, Phellodendri Chinensis Cortex, Aconiti Lateralis Radix) caused a remarkable decrease in extracted quantities of AQs. And the mixed decoction of rhubarb and mineral medicines (Natrii Sulfas, Gypsum Fibrosum, Ostreae Concha, Alumen) also resulted in less extracted quantities of AQs to varying degrees. Besides, more rhubarb AQs were extracted from mixed decoction with Curcuma than single decoction. But less rhubarb AQs were observed in mixed decoction with Lonicerae Flos, Rehmanniae, Artemisiae Herb and Forsythiae Fructus than single decoction to varying degrees. In the study, the maximum extracted quantities of AQs is 2. 3-fold higher than the minimum, the largest difference existed in the extracted quantity of physcion which was 13.5 times.
CONCLUSIONIn compatibility between rhubarb and different TMCs, mixed decoction and single decoction show different influences on extracted quantity of rhubarb AQs. It is proved that more AQs may be extracted from mixed decoction between rhubarb and saponin medicinal materials, whereas less AQs may be observed in mixed decoction between rhubarb and alkaloid medicinal materials.

Objective:To investigate the inhibitory effect of gallic acid on Pseudomonas aeruginosa biofilm. Methods:From January to June 2020, crystal violet staining was used to screen clinically isolated Pseudomonas aeruginosa biofilm strains in Taizhou Hospital of Integrated Traditional Chinese and Western Medicine. The minimal inhibitory concentration (MIC) of gallic acid against Pseudomonas aeruginosa was detected by the microdilution method. The adhesiveness of gallic acid to Pseudomonas aeruginosa and the minimum inhibitory membrane concentration (SMIC) were determined by (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) (XTT) assay. Results:PA08, PA12, PA18, PA35, PA53 and ATCC27853 strains were screened and used as test strains. The MIC of gallic acid against PA08, PA12, PA18, PA35, PA53 and ATCC27853 strains was 150 mg/L, 150 mg/L, 75 mg/L, 150 mg/L, 150 mg/L and 150 mg/L, respectively. Gallic acid at 75 mg/L could significantly inhibit the early adhesion of PA18 strain ( t = 3.766, P < 0.05). Gallic acid at 150 mg/L could significantly inhibit the early adhesion of PA08, PA12, PA18, PA35, PA53, ATCC27853 ( t = 4.562, 3.787, 6.769, 11.29, 5.719 and 7.251, all P < 0.05). Gallic acid at 300 mg/L could significantly inhibit the adhesion of PA18 strain at 6 hours ( t = 6.012, P < 0.05). The SMIC 50 of PA12, PA35, PA53 was 75 mg/L, and that of PA08, PA18, ATCC27853 was 150 mg/L. Conclusion:Gallic acid can effectively inhibit the early adhesion of Pseudomonas aeruginosa and affect its biofilm formation.
