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.

Objective: To study the clinicopathologic characteristics, immunophenotype and ALK gene alterations of gastrointestinal inflammatory myofibroblastic tumor. Methods: Clinical data, histological features and immunohistochemical results were analyzed in 7 cases of gastrointestinal inflammatory myofibroblastic tumor at Zhejiang Province Taizhou Hospital from January 2005 to December 2016. ALK gene status was investigated by ALK fluorescence in situ hybridization. Results: There were 4 female and 3 male patients. The age of patients ranged from 1 to 72 years (median age=53 years and mean age=40 years). The tumor was located in stomach (n=4), left hemicolon (n=1), right hemicolon (n=1) and rectum (n=1). Histologically, the tumors consisted of spindle fibroblast and myofibroblast cells growing in bundles with inflammatory infiltration primarily composed of plasma cells and lymphocytes. Immunohistochemical study showed spindle tumor cells were positive for vimentin (7/7), SMA (7/7), but were negative for CD34, CKpan, CD117, DOG1, S-100 and desmin. Two cases expressed ALK protein and fluorescence in-situ hybridization revealed the presence of ALK gene rearrangement in the both cases. Conclusions Gastrointestinal inflammatory myofibroblastic tumor is a rare neoplasm that is easily misdiagnosed. Its surgical removal is a reliable treatment. ALK may be a potential novel therapeutic target for inflammatory myofibroblastic tumor.

Objective To explore the application effects of nurse-physician combined outpatient service in peptic ulcer patients. Methods A total of 108 cases of peptic ulcer patients who were being treated in the digestive center of the Affiliated Hospital of Medical College of Ningbo University from January 2015 to February 2017 were recruited in the research by purposive sampling method, and randomly divided into experimental group and control group, with 54 cases in each. Nurse-physician combined outpatient service was provided to the patients in the experimental group, while the patients in the control group received traditional outpatient mode. Disease knowledge, medication compliance and lifestyle were compared between the two groups. Results In the 1st, 2nd and 6th week, patients' disease knowledge in the experimental group was better than that in the control group, and the difference was statistically significant (P<0.01). In the 2nd week, the medication compliance of the experimental group was better than that of the control group, with statistically significant (P<0.05). In the 1st, 2nd and 6th week, the number of smoking and drinking people was less than that of the control group, and the difference was statistically significant (P<0.05). Conclusions The nurse-physician combined outpatient service is beneficial to improve the knowledge level and medication compliance of patients and plays an important role in changing unhealthy living habits.

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.

Clinical decision-making is a series of activities of medical scheme selection, which determines the direction of medical behavior and the level of patients' welfare. In practice, clinical decision-making is not only restricted by medical technology factors, but also by non-technical factors. Therefore, it is necessary to analyze and predict the possible influence of non-technical factors in clinical decision-making. Game theory is a scientific system of strategic choice, which can effectively predict and analyze the impact of non-technical factors on clinical decision-making process. According to the game analysis results between doctors and patients, medical management and pharmaceutical enterprises, we can predict the non-technical impacts in clinical decision-making and their influence paths, guide clinical decision-makers to choose excellent strategies, abide by rationality and give up moderately, so as to improve the level of clinical decision-making and the welfare of patients.
