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.

ObjectiveTo explore the clinical and epidemiological value of semi-quantitative regional cerebral blood flow(rCBF)imaging in children with school phobia. Methods A total of 20 cases diagnosed with school phobia were examined with rCBF.Twelve were males and the other 8 were females.The mean age was(14.2?2.1)years(11-18 years).Semi-quantitative analysis methods were used to investigate the correlations among gender,age and rCBF. ResultsThere were significant differences in the rCBF of right fronto-parietal lobe,right occipital lobe,caput and putamen,left thalamus and hippocampus,and temporo-occipital lobe between males and females(P0.05).Only the PI of left temporo-parietal lobe of those ≥ 15 years old was significantly different from that of those

OBJECTIVES: To study the level of serum vitamin K₂ (VitK₂) and its association with bone metabolism markers osteocalcin (OC), type I procollagen amino-terminal peptide (PINP), and type I collagen carboxy-terminal peptide (CTX) in children. METHODS: A prospective analysis was performed on 1 732 children who underwent routine physical examination from October 2020 to October 2021. The serum levels of VitK₂ and 25-hydroxy vitamin D [25(OH)D] were measured. According to age, they were divided into four groups: <1 year, 1-3 years group, >3-6 years group, and >6-14 years. A total of 309 children with 25(OH)D≥50 nmol/L were screened out, and serum levels of OC, PINP, and CTX were measured to investigate the correlation of the serum levels of OC, PINP, and CTX with serum VitK₂ levels in different age groups. RESULTS: The prevalence rate of serum VitK₂ deficiency was 52.31% (906/1 732). The VitK₂ deficiency group had higher prevalence rates of overweight/obesity and growth pain (≥3 years of age) than the normal VitK₂ group (P<0.05). There were differences in the prevalence rate of serum VitK₂ deficiency (P<0.0083) and the serum level of VitK₂ (P<0.05) between the 1-3 years group and the >6-14 years group. The <1 year group had a higher serum level of CTX and a lower serum level of PINP than the >3-6 years group and the >6-14 years group (P<0.05). The <1 year group had a lower serum level of OC than the >6-14 years group (P<0.05). Serum VitK₂ level was positively correlated with OC level (r_s=0.347, P<0.01), and CTX level was negatively correlated with PINP level (r_s=-0.317, P<0.01). CONCLUSIONS Serum VitK₂ deficiency may be associated with overweight/obesity. Serum VitK₂ may affect the level of OC and even bone health.

OBJECTIVETo study the effect and mechanism of Bushen Tiaojing Recipe on improving oocyte and embryo qualities in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) at the super-ovulatory cycle.

METHODSFifty-eight tubal infertility patients undergoing IVF-ET were randomly assigned to two groups. Thirty patients in the treatment group were treated with Bushen Tiaojing Recipe and GnRHa/FSH/hCG, and twenty-eight patients in the control group were treated with GnRHa/FSH/hCG. Contents of GDF-9 in the mature follicular fluid were detected by Western blot. The expressions of GDF-9 in granulose cells were detected by Real-time PCR. The dose of gonadotropin (Gn), the number of oocytes obtained, the fertilization rate, the oocyte cleavage rate, the high quality embryo rate, and the pregnancy rate were compared.

RESULTSThe contents of GDF-9 in the follicular fluid and its expression in granulosa cells were significantly higher in the treatment group than in the control group (P<0.05). The number of oocytes obtained, the fertilization rate, the high quality embryo rate, and the pregnancy rate were significantly higher in the treatment group than in the control group. There was no significant difference in the dose of Gn or the oocyte cleavage rate.

CONCLUSIONSBushen Tiaojing Recipe could improve the pregnancy rate of IVF-ET. Its mechanism might be possibly through regulating the GDF-9 contents in the follicular fluid and granulosa cells.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the expressions of drosophila mothers against decapentaplegic protein (Smadl), Smad5, Smad8, and Smad4 on human mural granulosa cells.

METHODSSixty-six patients undergoing in vitro fertilization-embryo transfer (IVF-ET) were randomly assigned to two groups in the ratio of 1:2, the treatment group and the control group. Twenty-three patients in the treatment group were treated with BTR and GnRHa/FSH/hCG, while forty-three patients in the control group were treated with GnRHa/FSH/hCG. The mRNA expressions of Smad1, Smad5, Smad8, and Smad4 on mural granulosa cells of the mature follicle were detected by real-time PCR on the ovum retrieval day. The expressions of Smad1, Smad5, Smad8, and Smad4 at the protein level were observed using cell immunofluorescence method.

RESULTSThe mRNA and protein expressions of Smadl in the granulosa cells were significantly higher in the treatment group than in the control group (P <0.05). There was no statistical difference in the mRNA and protein expressions of Smad5, Smad8, and Smad4 between the two groups.

CONCLUSIONThe mechanisms of BTR for improving the pregnancy rate and the ovarian functions might be correlated with up-regulating mRNA and protein expressions of Smadl of human mural granulosa cells.

BACKGROUNDBell's palsy involves acute facial paralysis due to inflammation of the facial nerve. Acupuncture and moxibustion (acu-moxi) is beneficial in treating facial palsy. In order to verify the efficacy of acu-moxi on Bell's palsy, a randomized single-blind, multicenter clinical trial was performed.

METHODSA total of 480 patients from four clinical centers were involved in this trial, of whom 439 completed the trial and 41 did not. All patients were randomly assigned to either the control group or to one of two treatment groups. The control group was treated with prednisone, vitamin B1, vitamin B12, and dibazole; the treatment groups were treated either with acu-moxi alone or in combination with prednisone, Vitamin B1, vitamin B12, and dibazole. Symptoms and signs, the House-Brackmann scale, and facial disability index (FDI) scores were assessed and determined both pre- and post-treatment to evaluate the effectiveness of the treatment methods.

RESULTSThe characteristics of the control and two treatment groups were comparable without statistically significant differences before treatment. There were significant differences between the control and treatment groups after treatment (chi(2) = 15.265, P = 0.018). According to evaluations based on the House-Brackmann scale and FDI scores, the effectiveness of treatment in the two treatment groups was better than in the control group and was most effective in patients receiving acu-moxi treatment alone (Z = -2.827, P = 0.005).

CONCLUSIONThe efficacy of acu-moxi treatment for Bell's palsy is verified scientifically.

OBJECTIVEThe purpose of this study was to investigate the value of postoperative chemotherapy for locally advanced rectal cancer patients who reached pathological ypT1-4N0 after neo-adjuvant chemoradiotherapy.

METHODSWe performed a retrospective study of 104 patients treated with preoperative chemoradiotherapy followed by radical resection, who achieved pathological ypT1-4N0, between Mar 2003 and Dec 2010. There were 73 patients who received postoperative adjuvant chemotherapy, and the other 31 patients did not. The distribution of final pathologic stages for these patients was ypT1-2N0 in 39 cases and ypT3-4N0 in 65 cases.

RESULTSThe median follow-up was 41 months. The 3-year overall survival rate (OS) and recurrence-free survival rate (RFS) for the whole group (ypT1-4N0) were 93.4% and 85.3%, respectively. The 3-year OS and RFS in the adjuvant chemotherapy group and non-adjuvant chemotherapy group were 95.5%, 88.6% and 88.6%, 77.2%, respectively. There were no significant differences in 3-year RFS (P = 0.108) and OS (P = 0.106) between the two groups. The 3-year local recurrence and distant metastasis rates in the adjuvant chemotherapy group were 4.1% (3/73) and 5.5% (4/73), while for the non-adjuvant chemotherapy group, the 3-year local recurrence rate and distant metastasis rate were 3.2% (1/31) and 16.1% (5/31), respectively. Significant difference was found in distant metastasis rates (P = 0.030) between the two groups, but not in local recurrence rates (P = 0.676).Further subgroup analysis indicated that for the ypT1-2N0 patients, there were no significant differences in 3-year OS (P = 0.296) and RFS (P = 0.939) between the adjuvant and non-adjuvant chemotherapy groups, while negative results displayed in 3-year local recurrence rates (P = 0.676) and distant metastasis rates (P = 0.414). However, for patients with ypT3-4N0, significant differences were showed in both the 3-year OS (P = 0.034) and RFS (P = 0.025), and further analysis revealed that the 3-year distant metastasis rate was significantly higher in the non-adjuvant chemotherapy group than in the adjuvant chemotherapy group (P = 0.010) , but with non-significant difference in the 3-year local recurrence (P = 0.548).

CONCLUSIONSAdjuvant chemotherapy may not improve survival for ypT1-2N0 patients. However, it may be clinically meaningful for ypT3-4N0 patients by decreasing distant metastasis rate. Further randomized controlled clinical trials are needed to confirm our results.
