Objective To study the mechanism of FTY720 on type Ι diabetic rats. Methods The typeⅠdiabetes rat model was established by feeding male SD rats with high energy urea and injecting into the abdominal cavity with low dose cephalosporins (STZ, 30 mg/kg). In the following, the treated rats were divided into two groups: model group and FTY720 group. Another group of untreated rats was assigned as normal control group. FTY720 group was given 1 mg/kg FTY720, the normal control group and model group was given the equal amount of water. Results The cardiac function of FTY720 group was recovered markeyly. FTY720 activated the expression of vascular endothelial cells S1P1 , diabetes and reduced the expessions of S1P3 and PKCβ Ⅱand it restored the migration ability of diabetes cardiovascular endothelial cell , as well as the abnormally elevated cardiovascular endothelial cells induced by high sugar permeability. Conclusion The S1P1 and S1P3 cut is an important reaction pathway to the complications of diabetes and cardiovascular dysfunction. FTY720 may reduce the damage to core blood vessels caused by diabetes , and pathological angiogenesis which functionally depends on the PKCβⅡ signaling pathways. Therefore, FTY720 may provide a potential therapy for cardiovascular function impaired by diabetes.

Objective: To observe the clinical effect of acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus electroacupuncture (EA) for treating peripheral facial paralysis and its influence on patients' facial nerve functions, facial disability index and clinical symptoms and signs. Methods: A total of 96 peripheral facial paralysis patients were allocated into an observation group, a medicine group and an EA group by simple randomization, with 32 cases in each group. Patients in the medicine group were treated with oral mecobalamine and prednisone acetate; patients in the EA group were treated with EA on the basis of the medicine treatment; while patients in the observation group were treated with acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA. After 4-week treatment, the clinical efficacy, the adverse events, and the scores of House-Brackmann (H-B) facial nerve function grading scale, visual analog scale (VAS), clinical symptoms and signs, and facial disability index (FDI) were compared. Results: After 4-week treatment, the total effective rate was 96.9％ in the observation group, higher than 68.7％ in the medicine group and 75.0％ in the EA group (both P<0.05). After 4-week treatment, the scores of H-B grading scale, VAS and clinical symptoms and signs in the three groups dropped significantly compared with those before treatment, and the scores in the observation group were lower than those in the medicine group and EA group (all P<0.05). After 4-week treatment, the facial disability index-physical function (FDIP) in the FDI in the three groups increased significantly, with a higher value in the observation group compared with that in the medicine group and EA group (both P<0.05). The facial disability index-social function (FDIS) in the FDI dropped significantly, with a lower score in the observation group compared with that in the medicine group and EA group (both P<0.05). However, the comparisons of the items above between the medicine group and the EA group showed no statistical significance (all P>0.05). The between-group comparison of the adverse event across the three groups showed no statistical significance (P>0.05). Conclusion: Acupoint sticking therapy with Mian Tan Gao (facial paralysis paste) plus EA can decrease H-B grade, reduce pain severity and improve clinical symptoms and signs as well as the facial disability condition in peripheral facial paralysis patients. This method produced more significant efficacy compared with oral medicine and medicine plus EA.

Objective To investigate the clinical efficacy of Bushen Yijing Decoction for the treatment of xerophthalmia of kidney yang deficiency type and to observe its effect on serum Th1/Th17 cytokines.Methods From January 2021 to January 2023,a total of 96 patients with xerophthalmia of kidney yang deficiency type were selected as the study objects.According to the treatment methods,the patients were divided into observation group and control group,with 48 cases in each group.The control group was treated with Sodium Hyaluronate Eye Drops externally,and the observation group was given oral use of Bushen Yijing Decoction together with Sodium Hyaluronate Eye Drops externally.The course of treatment for the two groups covered 21 days.The changes of tear film break-up time(BUT),corneal fluorescein staining(FL)score,SchirmerⅠtest(SIT)value,serum Th1/Th17 cytokines,Ocular Surface Disease Index(OSDI)questionnaire scores,and 25-Item National Eye Institute Visual Function Questionnaire(NEI-VFQ-25)score in the two groups were observed before and after treatment.Moreover,the clinical efficacy and incidence of adverse reactions were compared between the two groups.Results(1)After 21 days of treatment,the total effective rate of the observation group was 95.83%(46/48),and that of the control group was 70.83%(34/48).The intergroup comparison(tested by chi-square test)showed that the clinical efficacy of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the ocular surface function indicators of BUT and SIT values in the two groups were higher and the FL values were lower than those before treatment(P＜0.05).The increase of BUT and SIT values and the decrease of FL values in the observation group were significantly superior to those in the control group(P＜0.01).(3)After treatment,the levels of serum cytokines of interleukin 17(IL-17),tumor necrosis factor alpha(TNF-α)and interferon gamma(IFN-γ)in the two groups were lower than those before treatment(P＜0.05),and the decrease of serum IL-17,TNF-α and IFN-γ levels in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the questionnaire scores of OSDI in the two groups were lower and the NEI-VFQ-25 scores were higher than those before treatment(P＜0.05).The decrease of OSDI scores and the increase of NEI-VFQ-25 scores in the observation group were significantly superior to those in the control group(P＜0.01).(5)The incidence of adverse reactions in the observation group was 4.17%(2/48),and that in the control group was 8.33%(4/48).There was no significant difference between the two groups(P＞0.05).Conclusion Bushen Yijing Decoction can enhance the clinical efficacy of xerophthalmia of kidney yang deficiency type,and the decoction is effective on alleviating the eye discomforts,improving the ocular surface function of patients,regulating the levels of Th1/Th17 cytokines,and relieving the inflammatory response without inducing severe adverse reactions while with high safety.

The purpose of the present work was to study the role of unilateral hippocampal neural network in hippocampal epileptogenesis and its cellular mechanisms. Experiments were performed on 45 Sprague-Dawley adult rats. Acute tetanization (60 Hz, 2 s, 0.4 - 0.6 mA) of the right posterior dorsal hippocampus (ATPDH) was used to induce hippocampal epilepsy. The single unit discharges and the depth electrographs were synchronously recorded with a glass microelectrode and a pair of stainless concentric electrodes in the ipsilateral anterior dorsal hippocampus (HPC). The results demonstrated that: (1) some primary unit after-discharges were synchronized with electrographic after-discharges in the anterior dorsal HPC network after eight or nine tetanic trains were administered. Others desynchronized with 5 - 90 Hz primary depth electrographic after-discharges; (2) primary electrographic after-discharges were driven by primary unit after-discharges in the anterior dorsal HPC; (3) primary unit after-discharges were induced by brief primary electrographic after-discharges; and (4) plasticity of primary electrographic after-discharges and inhibition of single neuron firing were induced by repetitive ATPDH. The results suggest that hippocampal pathophysiologic network along the temporal-septal axis of the HPC is re-established by the repetitive ATPDH. There are plastic interactions between single neurons and its network during this re-establishment, which may be involved in the generation of "seizure oscillation". Over-activation of an intrinsic inhibition of the HPC along its temporal-septal axis might be involved in hippocampal network epileptogenesis.

The aim of the present study was to study the effect of β-estradiol (β-E(2)) on the large-conductance Ca(2+)-activated potassium (BK(Ca)) channel in mesenteric artery smooth muscle cells (SMCs). The mesenteric arteries were obtained from post-menopause female patients with abdominal surgery, and the SMCs were isolated from the arteries using an enzymatic disassociation. According to the sources, the SMCs were divided into non-hypertension (NH) and essential hypertension (EH) groups. Single channel patch clamp technique was used to investigate the effect of β-E(2) and ICI 182780 (a specific blocker of estrogen receptor) on BK(Ca) in the SMCs. The results showed the opening of BK(Ca) in the SMCs was voltage and calcium dependent, and could be blocked by IbTX. β-E(2) (100 μmol/L) significantly increased open probability (Po) of BK(Ca) in both NH and EH groups. After β-E(2) treatment, NH group showed higher Po of BK(Ca) compared with EH group. ICI 182780 could inhibit the activating effect of β-E(2) on BK(Ca) in no matter NH or EH groups. These results suggest β-E(2) activates BK(Ca) in mesenteric artery SMCs from post-menopause women via estrogen receptor, but hypertension may decline the activating effect of β-E(2) on BK(Ca).

Background: Extensive studies have confirmed the efficacy of taxanes in combination with anthracycline-basedchemotherapy on breast cancer. However, few studies have assessed the efficacy of weekly taxane–anthracyclineregimens on locally advanced breast cancer. This study was to compare the efficacy and safety of a weekly taxane–anthracycline regimen with those of tri-weekly anthracycline-based regimen in patients with locally advanced breastcancer.Methods: Patients with locally advanced breast cancer were randomized to receive 4–6 cycles of neoadjuvant chemotherapywith tri-weekly 5-fluorouracil–epirubicin–cyclophosphamide (FEC) regimen or weekly paclitaxel–epirubicin(PE) regimen. The primary endpoint was the pathologic complete response (pCR) rate. Other endpoints included theclinical tumor response, breast-conserving surgery rate, and adverse events.Results: Between March 2010 and September 2013, 293 patients were randomized to the FEC (n = 151) and PE(n = 142) arms. The overall clinical response rate was significantly higher in the PE arm than in the FEC arm (76.06% vs.59.95%, P = 0.001). Consistently, the post-chemotherapy pathologic T and N stages were significantly lower in the PEarm than in the FEC arm (P < 0.001). However, the pCR rate was similar in the two arms (10.61% vs. 12.31%, P = 0.665).Overall, 36 (27.27%) patients in the FEC arm and 6 (35.28%) in the PE arm were qualified for breast-conserving surgery.Most adverse events were comparable in both arms, with more severe neutropenia in the PE arm than in the FEC arm(11.97% vs. 5.96%, P = 0.031).Conclusions: In patients with locally advanced breast cancer, weekly PE was not superior to FEC in terms of pCR.However, weekly PE has a higher response rate and superior down-staging effects. On this account, the PE regimenmay be considered an alternative option for locally advanced breast cancer. Long-term follow-up data are needed toconfirm the efficacy of this regimen on locally advanced breast cancer.
