OBJECTIVETo study the effect of 1-tetrahydropalmatine (1-THP) on the spontaneous electric discharge (SED) induced by chronic dorsal root ganglion neurons compression.

METHODSUsing single fiber recording method, the SED of 84 neurons class A induced by compression were recorded. The effect of 1-THP on the SEDs and its relation with concentration were observed.

RESULTSIn the 84 SED of neurons, 25 showed periodical rhythmicity (PR) and 59 showed non-periodic rhythmicity (non-PR). 1-THP (100 micromol/L) inhibited SED in 16.0% (4/25) of neurons with PR and 67.8% (40/59) of neurons with non-PR (P < 0.01) in an effect-dose dependent manner, the higher the concentration of 1-THP, the more the inhibition, with quicker inhibiting in initiation and longer time needed for recovery. SED in 57.1% neurons were recovered 20 min after elution, but unrecovered even after 3 h in the others.

CONCLUSION1-THP shows inhibitory effect on the A-fiber SED induced by chronic dorsal root ganglion neurons compression.

OBJECTIVETo observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients.

METHODSForty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM.

RESULTSCompared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01).

CONCLUSIONCCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

Objective To explore the clinical characteristics and therapy of brucellar meningitis in children.Method One case of brucellar meningitis was reported and relevant literatures were reviewed.A 10 years old boy was admitted to hospital with a history of half a month fever and cough and 3 days headache.His family raised sheep,but he denied contacting closely with sheep and eating raw goat's milk and mutton.Results The course of this reported child was subacute.Clinical manifestations included fever,headache and meningeal irritation sign positive.The cerebrospinal fluid(CSF)findings were similar to those of tuberculous meningitis,where WBC count was elevated with predominant lymphocytes,glucose and chloride decreased and protein increased.The serum bacterium burgeri antibody was positive,agglutination titer was 1160.After brucellar meningitis was diagnosed,three antibiotics including rifampin,minocycline and ceftriaxone sodium and other symptomatic treatment were used.The CSF findings were normal 2 weeks later.This child taked orally minocycline,rifampin and trimethoprim-sulfamethoxazole for 8 weeks post discharge,the recovery was good.The domestic and foreign documents showed that the incidence of the nervous system complications of brucellosis in children was lower than that in adult.The main clinical manifestations were acute meningitis /meningocephalitis.Brucellar meningitis could be misdiagnosed as tuberculous meningitis,because the course of disease,clinical manifestations and CSF findings were similar.Therapeutic alliance including 3 kinds of antibiotics,which could easily pass through blood-brain barrier,was used to treat brucellar meningitis.The total course of treatment shouldn't be shorter than 8 weeks.Conclusions Brucellar meningitis should be screened through epidemiological investigation,serum agglutination test and cerebrospinal fluid culture,in case the reason of meningitis of meningoencephalitis is unknown,especially its clinical manifestation resembles to tuberculous meningitis.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.

RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).

CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

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.
