OBJECTIVETo study the effect of Bushen Wenyang Huayu Recipe (BSWYHYR) on nerve growth factor (NGF) and transient receptor potential vanilloid receptor I (TRPV1) in experimental endometriosis (EMT), and to explore its mechanism for treating EMT-induced pain.

METHODSTotally in-bred line BALB/c 75 female mice were divided into five groups, i.e., the sham-operation group, the model group, the high dose BSWYHYR group, the low dose BSWYHYR group, the gestrinone group, 15 in each group. Writhing response was observed in each group. Serum contents of NGF were detected using ELISA. Expression levels of NGF and TRPV1 in uterus and ectopic foci were detected using immunohistochemical staining SP and Western blot. mRNA expression levels of NGF and TRPV1 in uterus and ectopic foci were detected by Real-time PCR.

RESULTSThe serum NGF content in the model group was higher than that in the sham-operation group (P < 0.01), and there was positive correlation between NGF and the writhing frequency (r = 0.574, P < 0.01). Compared with the model group, serum levels of NGF significantly decreased in the 3 treatment groups (P < 0.05). Compared with the sham-operation group, mRNA and protein expression levels of NGF and TRPV1 increased significantly in the model group (P < 0.01). Protein expression levels of NGF and TRPV1 decreased significantly in the 3 treatment groups, when compared with the model group (P < 0.01). mRNA expression levels of NGF and TRPV1 decreased most in the high dose BSWYHYR group (P < 0.01). NGF in uterus and ectopic foci was positively correlated with protein and mRNA expression levels of TRPV1 (P < 0.01).

CONCLUSIONSNGF and TRPV1 participated in the occurrence of pain in EMS. BSWYHYR played an important role in inhibiting EMT-induced pain through reducing the up-regulation of NGF on TRPV1.

Objective To evaluate the safety and clinical efficacy of the treatment for symptomatic uterine fibroids with MR guided focused ultrasound surgery(MRgFUS)in China. Methods Twenty five selected patients with symptomatic uterine fibroids underwent MRgFUS treatment in our perspective clinical study. Immediately after treatment the patients accepted pelvic enhanced MRI scans, and recorded the non-perfused volume(NPV)and calculated the non-perfused volume ratio(NPV%). We recorded the symptom severity score(SSS) and standard SSS change(ΔSSS)of the patients before, during and 1 week after treatment together with 1, 3, 6, 12 months and several years follow-up. The patients accepted pelvic enhanced MRI scans in the follow-up of 12 months after treatment,and recorded the volume and the volume change(ΔV) of fibroids. We observed the adverse reactions during the treatment and the follow-ups. Wilcoxon test or t test and Pearson or Spearman correlation analysis were used to analyze the data. Results Totally 31 fibroids of 25 patients were completed the treatment. Twenty two patients completed the 12 months follow-up and 15 patients completed the long-term follow-up which was during 34 to 66 months, median follow-up duration was(55 ± 11)months. The NPV was 4.5 to 295.0 cm3, median was 37.0 cm3. The NPV%was 6%to 94%, average was(64 ± 23)%. According to our follow up, the standard SSS continued to decline. Compared with screening standard SSS, all the follow-up standard SSS had significant difference(P<0.05), except for that of the first week. Among all the follow up, only the standard SSS change of 1 week after the treatment had a correlation with NPV%(r=0.552,P=0.005), and the others had no significant correlation with NPV%(P>0.05). The uterine fibroids volume decreased in the 12 months follow-up, which had a significant difference with the volume before treatment(P<0.05). And there was also correlation between the fibroids volume change and NPV(r=0.587,P=0.017). There was no correlation between the volume or volume change and standard SSS or standard SSS change(all P>0.05). None serious adverse effects occurred in all cases. Conclusion MRgFUS is a safe and effective way to treat uterine fibroids.

OBJECTIVETo observe the effect of Chuanhuang No.1 Recipe (CHR) on renal function and micro-inflammation in phase 3 chronic kidney disease (CKD) patients.

METHODSTotally 60 phase 3 CKD patients were randomly assigned to the treatment group (treated by CHR) and the control group (treated by Losartan Potassium), 30 in each group. All patients received basic treatment. Patients in the treatment group took CHR decoction, 400 mL each time, one dose per day, while those in the control group took Losartan Potassium, 50-100 mg per day. All medication lasted for 24 weeks. Changes of serum creatinine (SCr), blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), serum uric acid (UA), 24 h urinary protein excretion (24 h U-pro), urinary microalbumin (U-Alb), high-sensitivity C-reactive protein (hs-CRP), serum tumor necrosis factor (TNF)-alpha, and serum IL-6 were detected and compared before and after treatment. Efficacy was also compared.

RESULTSCompared with before treatment, SCr and BUN significantly decreased in the treatment group (P<0.05, P<0.01); eGFR in- creased (P<0.05). Only UA obviously decreased in the control group (P<0.05), but with no obvious change in SCr, BUN, or eGFR. Compared with before treatment, 24 h U-pro decreased after treatment in the treatment group (P<0.05), but with less decreased level when compared with the control group. U- Alb was also significantly decreased in the control group (P<0.01). There was statistical difference in 24 h U-pro and U-Alb between the two groups after treatment (P<0.05). Compared with before treatment, hs-CRP obviously decreased after treatment in the two groups, but serum levels of TNF-alpha and IL-6 obviously decreased only in the treatment group (P<0.05). The total effective rate was obviously higher in the treatment group than in the control group (70.00% vs. 43.33%, P<0.01).

CONCLUSIONCHR could efficiently improve the renal function of phase 3 CKD patients and alleviate the micro-inflammation.

OBJECTIVETo study the effects of citalopram on the expression of proliferating cell nuclear antigen (PCNA) and proto-oncogene protein (C-fos) and cell apoptosis in frontal cortical neurons of rat after stress.

METHODSTwenty four healthy male SD rats were randomly divided into three groups (n = 8): control group, stress group (treated with saline, ig) , experimental group (treated with Citalopram 4 mg/kg x d for 28 days, ig). Rats were forced to swim to establish chronic stress model. The protein expression levels of PCNA and C-fos were tested by immunohistochemistry assay. TUNEL assay was used to test cell apoptosis. Nikon image analysis software was used to determine the number of positive cells in each index.

RESULTSCompared with the control group, the stress group showed a smaller amount of PCNA-positive cells, a larger number of C-fos positive cells, and the volume of positive cells was significantly reduced. Compared with the stress group, the PCNA positive cells were increased significantly, the C-fos positive cells and TUNEL positive cells were decreased significantly, nuclear condensation phenomenon in frontal cortical neurons and the staining was significantly lighter in experimental group (P < 0.05).

CONCLUSIONCitalopram significantly antagonize PCNA, C-fos protein expression and cell apoptosis of rat prefrontal cortical neurons caused by chronic stress, which might be the one of mechanisms of citalopram for prevention and treatment of psychosis caused by chronic stress.
