Objective To explore the effectiveness of sandplay therapy combined with family counseling in children with school phobia and its influence of child′ self-consciousness. Methods Integrative sandplay therary with family consulting were used to treat 28 patients with school phobia regularly for 2 months. Sandplay and family consulting therapy were given once a week for 45 minutes . Clinical outcomes were assessed using CGI-GI and Piers-Harris children′s self-consciousness scale before and after treatment as well as 3 months posttreatment. Results Overall response rate was 85%. In addition, the physical appearance and characteristic factor before and after treatment were no significant difference (P>0.05). The rest of the various factors and total score compared with pre-treatment significantly improved (P<0.05). After treatment for 3 months, every factor in self-consciousness of children and total score were no significant difference (P>0.05). Conclusion Integrative sandplay therapy with family counseling has better and long-lasting treatment effect to self-consciousness of children with school refusal.

Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.

Objective To investigate the effect of bipolar coagulation hemostasis on ovarian function in patients with laparoscopic ovarian endometriosis cyst stripping.Methods From January 2015 to February 2016, 88 cases of ovarian endometriosis cyst were selected by using the random number table method.They were randomly divided into observation group and control group,44 cases in each group.The observation group was treated with bipolar coagulation hemostasis,and the control group was treated with endoscopic suturing.The luteinizing hormone(LH), follicle stimulating hormone(FSH),estradiol(E2 ),sinus follicle number(FO )and ovarian stroma systolic blood flow velocity peak preoperation,postoperation and postoperative 6 months were detected.Results The E2 levels in the observation group postoperation and postoperative 6 months were (190.03 ±30.88 )pmol/L and (179.82 ± 29.94)pmol/L,which were significantly lower than those in the control group [(230.04 ±32.22 )pmol/L and (232.49 ±28.41)pmol/L,t =5.947,9.465,all P <0.05].The FSH levels in the observation group postoperation and postoperative 6 months were (12.01 ±2.10)mIU /mL and (12.09 ±1.99)mIU /mL,which were significantly higher than those in the control group[(9.20 ±2.08)mIU /mL and (9.18 ±1.10)mIU /mL,t =6.306,8.489,all P <0.05].The LH levels in the observation group postoperation and postoperative 6 months were (9.93 ±1.73)mIU /mL and (9.81 ±1.78)mIU /mL,which were significantly higher than those in the control group[(8.94 ±1.80)mIU /mL and (9.03 ±1.91)mIU /mL,t =2.630,1.982,P <0.05].The FO levels in the observation group postoperation and postoperative 6 months were (7.60 ±1.85)and (8.81 ±1.23),which were significantly lower than those in the control group[(8.77 ±1.90)and (9.43 ±1.44),t =2.927,2.172,all P <0.05].The PSV levels in the observation group postoperation and postoperative 6 months were (0.07 ±0.02)m/s and (0.09 ±0.01)m/s,which were signifi-cantly lower than those in the control group[(0.09 ±0.01)m/s and (0.12 ±0.01)m/s,t =5.933,14.071,all P <0.05].The ovarian reserve function in the observation group decreased in 6 cases(13.64%),which in the control group was 5 cases(11.36%),the difference was not statistically significant(P >0.05).Conclusion The application of different hemostatic methods in laparoscopic ovarian endometriosis cyst stripping have effect on ovarian reserve function,but bipolar coagulation and hemostasis can significantly decrease ovarian reserve function,and it should be used as little as possible during the operation.

AIM:To synthesize the human platelet factor-4(hPF4) gene with a convenient and effective approach, and high express the hPF4 gene in E. coli BL21 (DE3). METHODS: According to the primary structure of hPF4, the nucleotide sequence was synthesized using touch-down PCR method. The resultant gene fragment containing EcoR Ⅰ and Xho Ⅰ overhangs at 5' and 3' ends was cloned into the expression vector pGEX-4T-1 to construct the recombinant plasmid pGEX-4T-1-hPF4,which was then transformed into the E. coli strain BL21 (DE3). RESULTS: hPF4 gene was successfully synthesized by touchdown PCR method. A fusion protein composed of glutathione S-transferase (GST) and the recombinant hPF4 was expressed in BL21(DE3) by IPTG induction. The expression level of the fusion protein in E. coli was about 30% of the total cellular protein. CONCLUSION: Touch-down PCR may provide a convenient and effective approach to obtain other target genes. The expressed fusion protein forms the inclusion bodies, providing sufficient material for further purification and biological activities process.

OBJECTIVE:To investigate the pharmacokinetic characteristics of puerarin and puerarin lobate extract in rats and compare the difference of pharmacokinetic behavior of them. METHODS:24 SD rats were randomly divided into high-dose and low-dose groups of puerarin (300,100 mg/kg) and puerarin lobate extract (equal to 300,100 mg/kg of puerarin). 0.2 ml blood sample were collected from posterior venous plexus of bulbus oculi before intragastric administration and 0.083,0.17,0.33,0.5, 0.67,1,1.5,2,3,4,6,8,10 h after administration,respectively. The pharmacokinetic parameters were calculated by using DAS 3.0 software. RESULTS:Compared with puerarin high-dose group,AUC0-t and cmax of puerarin low-dose group increased sig-nificantly,while CL decreased significantly;MRT0-t of puerarin low-dose group and puerarin lobate extract high-dose and low-dose groups decreased significantly (P<0.01). There was no statistical significance in pharmacokinetic parameters between puerarin lo-bate extract low-dose group and puerarin lobate extract high-dose group (P>0.05). CONCLULSIONS:There is difference in the pharmacokinetic behavior between puerarin and puerarin lobate extract in rats. Some components of puerarin lobate extrats maybe speed up the elimination of puerarin in rats,so as to shorten the average retention time of it.
