Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

CD40 and its receptor CD40L are a very important pair of co-stimulating molecule in immune response, which have extensive biological effects. After stimulating CD40 signal, it can exert corresponding function through MAPK (JNK, ERK, p38) pathway, PI3K cascade, as well as NF-κB and STAT. The CD40 signal is closely related to tumor immunity, this moleculer has already become targeted-molecule for cancer treatment. Recently, there have been many anti-CD40 monoclonal antibodies displaying good anti-cancer effect, among which CHIR-12.12, SGN-40 and CP-870, 893 developed rapidly and successively have entered clinical research stage. This review focuses the status of anti-CD40 monoclonal antibody, including distribution of CD40, physiological function of CD40, CD40 and tumor immunity, anti-CD40 monoclonal antibodies and so on.

OBJECTIVETo determine the possible difference in vasodialtation effect of quercetin and rutin.

METHODSThe isolated rat thoracic aorta was treated with phenylephrine (PE), and the effects of quercetin and rutin on the preconstricted aorta rings with or without endothelium were determined by organ bath technique. Nitric oxide synthase inhibitor L-N(G)-nitroarginine methyl-ester (L-NAME), guanylyl cyclase inhibitor methylene blue, cyclooxygenase inhibitor indomethacin were used to explore the mechanism.

RESULTSQuercetin (10-160 micromol/L) caused vasorelaxation of aorta rings preconstricted with PE in endothelium-intact and denuded aorta rings in a dose-dependent manner. Rutin(10-160 micromol/L) caused dose-dependent vasorelaxation in endothelium-intact rings preconstricted with phenylephrine, but not in denuded aorta rings. The maximal response (Rmax) values calculated from vasorelaxation curves of quercetin and rutin were (77.20+/-6.11)% and (44.28+/-7.48)%, respectively. There was no difference between median effective concentration (EC(50)) values of quercetin and rutin. Pretreatment with L-NAME (0.1 mmol/L) abolished the vasorelaxation by rutin,but did not influence the vasodilating effect of quercetin in endothelium-intact rings. Pretreatment with methylene blue (10 mmol/L) canceled the vasorelaxation both by quercetin and rutin. Pretreatment with indomethacin (10 micromol/L) attenuated the vasodilatation of quercetin, but did not affect the vascular effect of rutin.

CONCLUSIONThe vasodilatation effect of quercetin is more potent than rutin. The vasodilatation effect of quercetin might be mediated by guanylyl cyclase and cyclooxygenase-dependent pathway, while the vasodilatation by rutin might be via nitric oxide-guanylyl cyclase pathway.

OBJECTIVETo observe the differences in onset time and the overall efficacy of the acupuncture therapy of dredging Governor Vessel and regulating mentality combined with fluoxetine and the fluoxetine for post-stroke depression(PSD).

METHODSSixty-three patients were randomly divided into an acupuncture intervention of dredging Governor Vessel and regulating mentality group(acupuncture and medication group, 33 cases) and a control group (medication group, 30 cases). In the medication group, 20 mg fluoxetine was used by oral administration, once a day at 7:00 in the morning, continuously for 4 weeks. In the acupuncture and medication group, based on the oral administration of fluoxetine, the acupuncture intervention of dredging Governor Vessel and regulating mentality was applied mainly at Baihui(GV 20), Fengfu(GV 16), Shenting(GV 24), Shuigou(GV 26), Dazhui(GV 14) and Shendao(GV 11), once a day, 6 times a week, continuously for 4 weeks. Twenty-four items in Hamilton Depression Scale(HAMD), modified Edinburgh Scandinavia Stroke Scale(MESSS) and activity of daily life scale(ADL, Barthel index, BI) were used before and after 2-week and 4-week treatment. The efficacy was compared between the two groups.

RESULTSAfter 2-week treatment, the HAMD score and the MESSS score in the acupuncture and medication group were obviously decreased and the BI score was apparently increased(all P<0. 01). In the medication group, however, the score of every scale was not statistically different from that before treatment(P'>0. 05). After 4-week treatment, HAMD scores and MESSS scores in the two groups were obviously decreased and the BI scores I were apparently increased(all P<0. 01). After 2-week and 4-week treatment, the HAMD scores and the MESSS scores in the acupuncture and medication group were lower than those in the medication group and the BI scores were higher than those in the medication group(P<0. 01, P<0. 05). The total effective rate of anti-depression (97. 0%, 32/33) the total effective rate of nerve function impairment(90. 9%, 30/33) and the total effective rate of daily life activity(97. 0% 32/33) in the acupuncture and medication group were better than 80. 0% (24/30), 80. 0%(24/30), 83. 3%(25/30) in the medication group(all P<0. 05).

CONCLUSIONThe acupuncture therapy of dredging Governor Vessel and regulating mentality could reduce the onset time of anti-depression medicine treatment of PSD and enhance the overall efficacy. Therefore, it enhances the clinical compliance.

Objective To observe the effect of different thyroid hormone level on the expression of synaptotagmin Ⅰ(Syt Ⅰ) in adult rat hippocampus. Methods All 28 adult male SD rats were assigned randomly into hypothyroid, hyperthyroid and control group, hypothyroid group was established by daily intraperitoneal injections with propylthiou raci(PTU, 10.0 mg/kg body weight) for 6 weeks and hyperthyroid group with L-Thyroxine (L-T4, 0.5 mg/kg body weight) for 3 weeks. Radioimmunity method was used to assay the levels of serum T3 and T4, immunohistochemical S-P technology to assay the levels of Syt Ⅰ protein in hippoeampus CA1, CA3 and dentate gyrus (DG). The layers analyzed in the different subfields include the polymorphic cell layer(the stratum oriens, SO), pyramidal cell layer(PCL), stratum radiatum (SR), lacunosum-molecular layer (SLM) in CA1 and CA3, granular cell layer(GL) and molecular layer(ML) in DG. Results The levels of serum T3 and T4[(0.34±0.12), (41.03± 11.37)nmol/L]in the hypothyroid rats were significantly lower than those in the control group[(0.65±0.15), (55.20±10.68)nmol/L, P < 0.01 or < 0.05], and the positive granule of Syt Ⅰ was significantly lower in PCL and SR of CA1 and CA3, GL of DG. The average optical value responsible for Syt Ⅰ immunoreactivity was obviously reduced in SO(0.048±0.007), PCL(0.299±0.035), SR(0.042±0.007), SLM(0.038±0.006) of CA1, PCL(0.085± 0.019), SR(0.040±0.011), SLM (0.038±0.006) of CA3, GL (0.076±0.019) of DG than normal controls (0.068± 0.014, 0.376±0.053, 0.053±0.008,0.056±0.009,0.118±0.026,0.052±0.010,0.053±0.009,0.099±0.015; P< 0.01 or < 0.05). Serum T3 and T4 levels [(1.43±0.30), (157.18±19.95)nmol/L]of hyperthyroid rats were significantly higher than those of control group(P < 0.01). The value was reduced in PCL(0.322±0.050), SR(0.039±0.006), SLM (0.042±0.006) of CA1, PCL(0.098±0.034), SR(0.046±0.013), SLM(0.046±0.010) of CA3 and GL(0.085± 0.024), ML (0.042±0.009) of DG (P < 0.05 or < 0.01). Conclusion Adult-onset of hypothyroidism and hyperthyroidism can reversibly decrease the expression of Syt Ⅰ in CA1, CA3 and DG regions of hippocampus.

OBJECTIVETo investigate the cardiac effect of interleukin-2 (IL-2) and to explore the underlying mechanism.

METHODSThe video tracking system and spectrofluorometric method were used to measure the cell contraction and intracellular calcium. Fura-2/AM was used as a calcium fluorescence probe. Langendorff perfusion technique was used to determine the effect of IL-2 on the intact heart.

RESULTSCompared with the control group, IL-2 5 U/ml, 50 U/ml significantly decreased cell contraction amplitude [(74.95+/-4.79) vs (98.09+/-5.02)%, (64.30+/-5.24) vs (97.38+/-4.05)%], peak velocity of cell shortening [(70.23+/-4.85)% vs (98.09+/-5.46)%, (61.15+/-5.20)% vs (97.38+/-6.85)%], peak velocity of cell relengthening [(71.22+/-4.79)% vs (98.32+/-6.08)%, (68.16+/-5.24)% vs (97.55+/-5.00)%] and end- diastolic cell length [(88.28+/-5.84)% vs (97.95+/-5.52)%, (84.18+/-6.52)% vs (98.94+/-6.76)%]. IL-2 (5 U/ml, 50 U/ml) also markedly inhibited intracellular calcium transient [(74.94+/-4.90)% vs (98.09+/-3.74)%,(71.00+/-5.28)% vs (97.38+/-5.52)%], and elevated end-diastolic calcium level of ventricular myocytes [(113.91+/-5.93)% vs (100.10+/-3.02)%, (119.09+/-7.12)% vs (100.52+/-6.00)%], which were attenuated by the opioid receptor antagonist naloxone (Nal,10 nmol/L). In the isolated perfused rat heart,when compared with the control group, IL-2 50 U/ml markedly decreased left ventricular developed pressure [(79.91+/-2.18) vs (93.84+/-2.94)mmHg], maximal rate of rise of left ventricular pressure [(2370.7358.29) vs (2591.50+/-62.81)mmHg] maximal rate of fall of left ventricular [-(1460.95+/-38.6) vs -(1634.24+/-54.05) mmHg/s] and heart rate [(217.35+/-10.56) vs (244.52+/-11.23) beats/min], but increased left ventricular end-diastolic pressure (11.44+/-1.02 vs 9.23+/-0.46). Pretreatment with Nal (10 nmol/L) antagonized the cardiac depression and left ventricular end-diastolic pressure elevation induced by IL-2.

CONCLUSIONThe cardiac effect of IL-2 is mediated by opioid receptors on the membrane of cardiomyocytes.

OBJECTIVETo investigate the mechanism of the negative inotropic effect of tumor necrosis factor-alpha (TNF-alpha) in cardiomyocytes.

METHODSThe spectrofluorometric method was used to verify the calcium handling of the single myocyte. The activities of Ca(2+)-ATPase of sarcoplasmic reticulum (SR) and the activities of Ca(2+)-ATPase and Na(+)/K(+)-ATPase of plasma membrane were measured with colorimetric methods.

RESULTSTNF-alpha at 20 U/ml and 200 U/ml depressed the contractility of ventricular papillary muscle to 91% and 76% of control (P<0.01) respectively, but had no effect on the amplitude of electrically induced calcium transient in single myocyte. TNF-alpha inhibited the responsiveness of SR Ca(2+)ATPase activity to ATP (0.1 - 4 mmol/L) and Ca(2+) (1 - 40 micromol/L). TNF-alpha did not alter the activities of Ca(2+)-ATPase and Na(+)/K(+)-ATPase of plasma membrane compared with control group.

CONCLUSIONTNF-alpha decreases the myocardial contractility, at least partly, by inhibiting the activity of SR Ca(2+)- ATPase.
