Objective To investigate the association between early trauma experiences and obsessivecompulsive disorder (OCD). Methods One hundred and eighty-five patients who met with OCD diagnosis of DSM-Ⅳ and one hundred and thirty-two healthy controls were recruited. Early trauma experience of all participants was assessed with Early Trauma Inventory-Short Form (ETI-SF) ,and severity of symptoms of OCD patients was evaluated with Yale-Brown Obsessive-Compulsive Severity Scale (Y-BOCS). Results When compared with controls, OCD group showed significantly higher in ETI-SF total score (3.55 ± 3.29 vs 1.51 ± 1.98, P ＜ 0. 01 ) and had greater in general trauma (0.89 ± 1.10 vs 0. 43 ±0.77, P＜0.01 ) ,physical abuse (0.98 ± 1.31 vs 0.65 ±1.04, P=0. 016),emotional abuse(1.43 ±1.61 vs 0.38 ±0.89, P＜0. 01),and sexual abuse(0.24 ±0.59 vs 0.06 ±0.30, P＜0. 01 ). Female OCD patients reported more sexual abuse than male patients(0.33 ±0.69 vs0. 16 ± 0.45, P = 0.049) . There was a negative correlation between onset age of obsessive symptoms and early trauma experiences(P ＜ 0. 01 ), except sexual abuse experiences (P = 0. 10). Conclusion OCD patients have much more childhood traumas, and the more trauma experiences are,the earlier onset of OCD is, which may associated with the development of obsessive-compulsive disorder.

AIM: To establish HPLC fingerprint of Sishen Pill and a determination of main component of Sishen Pills(Fructus Evodiae, Semen Myristicae, Fructus Psoraleae, etc.) by HPLC.

CONCLUSION: The quality standard of Sishen Pill was established firstly. It can be used for quality cantrol of Sishen Pill.

BACKGROUND: The special genetic law of short tandem repeat on chromosome X (X-STR) makes it incomparable with autosome markers in forensic identification. However, the population genetics data is far less than that of the autosome STR, and especially the haplotype data are rarely reported.OBJECTIVE: To study the genetic polymorphism of 12 X-STR loci in Shenzhen area by pedigree analysis, aiming to provide scientific and effective data for the application of X-STR in forensic medicine and genetics. METHODS: The blood samples of 118 families were taken to extract DNA by Chelex-100, followed by PCR amplification using Investigator Argus X-12 kit. The frequency of alleles of 231 unrelated individuals was counted by direct counting method and Excel software. Hardy-Weinberg equilibrium test was performed on 12 X-STR loci of female samples by chi-square test. Discrimination power and mean exclusion chance were calculated according to the formula. Pedigree analysis was done to identify haplotypes of female samples and the haplotype frequencies of 4 linkage groups in 111 fathers and 119 mothers were calculated using direct counting method and Excel software.RESULTS AND CONCLUSION: In this study, 349 haplotypes were obtained. There were 238, 139, 153 and 157 haplotypes in linkage groups X1-X4, respectively. The polymorphism of DXS10135 locus was the highest with 21 alleles,while the polymorphism of DXS7423 locus was the worst with only 4 alleles. The combined discrimination power was 0.99999999 in males and 0.99999999 in females. The combined mean exclusion chance was 0.99999999 in trio cases,and 0.99999811 in duo cases. These findings indicate that the X-12 detection system has high polymorphism in Shenzhen Han population, and has important application value in forensic individual identification and paternity testing.

Objective To constructthe nurse job satisfaction index evaluation system by analytic hierarchy process (AHP) so as to provide theoretical basis for nursing managers. Methods Semi-structured interviews and literature review were used in establishing the preliminary nurse job satisfaction evaluation index system.The Delphi method was applied in expert consultation and a three-level index system was established, the weight, the largest eigenvalue and the weight vector were all calculated. Index consistency was inspected. Results 4 first-level indicators, 13 second-level indicators and 39 third-level indicators were established.The weight was 1.630 0-3.280 0 for the first-level indicators, 0.4494-1.4723 for the second-level indicators and 0.0913-0.783 9 for the third-level indicators.The weight vector was 0.038-0.616 for the first-level indicators,0.045-0.750 for the second-level indicators and 0.041-0.875 for the third-level indicators.The max-eigenvalue was 4.231 for the first-level indicators,6.226 for the second-level indicators and 4.176 for the third-level indicators. The consistency test value of judgment matrix ranged from 0.000 to 0.077, and the consistency ratio was less than 0.1. Conclusions With distinct gradation,clear structure, reasonable weight and rich content, the index system provides a theoretical basis for the nurse job satisfaction evaluation.

Thearticle is aimed to find the correlation between bioactive components of XYE-E and the antidepressant efficacy, by analyzing the immovability time in tail suspension test (TST) and forced swimming test (FST). Using the method of gray relational analysis, correlation analysis and regression analysis, relating the peak area of each common peak of1H-NMR spectra with the immovability time in TST or FST, we found that there were total 14 chemical components identified in the1H-NMR spectrum of XYE-E. Among them, 8 compounds, including saikosaponin a, saikosaponin c, saikosaponin E, saikosaponin F, saikosaponin G, saikosaponin b2, atractylenolide I and atractylenolide II, had significant correlation with antidepressant efficacy.

Objective To compare the difference of early trauma experience between early-onset and late-onset obsessive-compulsive disorder(OCD),and the kinds of early trauma in the cause of OCD. Methods Three hundred and twenty-six patients with obsessive-compulsive disorder and 480 healthy con-trols were enrolled. Early Trauma Inventory-Short Form ( ETI-SF) was applied to assess the early trauma ex-perience,compare the difference of early trauma experience between early-onset ( n=138) and late-onset ( n=188) OCD,and the kinds of early trauma in the cause of OCD. Results There were significant differences in the early trauma experience between obsessive-compulsive disorder group and control group((3.90±3.61) vs (1.88±2.61), P<0.01).Scores of physical((1.12±1.38) vs (0.71±1.23), P=0.001),emotional((1.58± 1.71) vs (0.42±1.01), P<0.01),and sexual abuse((0.27±0.59) vs (0.09±0.36), P=0.001),and a gener-al traumatic experience((0.94±1.17) vs (0.66±1.09), P<0.01) were significant difference between patients and controls. Except sexual abuse((0.30±0.66) vs (0.24±0.67), P=0.42),there were significant differ-ences in the early trauma between early-onset and late-onset OCD((5.12±3.58) vs (3.01±3.38), P<0.01), especially emotional abuse((2.18±1.76) vs (1.12±1.53), P<0.01).247(75.8%) OCD patients and 79(57. 9%) healthy controls experienced early trauma(χ2=21.48, P<0.01). Experiencing one kind of early trau-ma,the prevalence of OCD was 39.1%,two kind was 61.0%,three kind of early trauma was 65.8%,and ex-periencing four or more kind of early trauma,the prevalence of OCD was up to 84.4%. Conclusion OCD patients have much more early trauma,especially early-onset OCD. Experiencing more kind of early trauma, and the prevalence of OCD higher may associated with the development of obsessive-compulsive disorder. It is important to consider the role of childhood trauma in the prevention and treatment of OCD.

In this study, we prepared various matrices of hydrogel patches and studied their cross-linking mechanism by observing their rheological properties, which could provide theoretical basis and deep technical support for further industrial development of hydrogel patch. Rheology method was used to do the amplitude scanning and single-frequency scanning for various hydrogel matrix, under the condition of oscillation mode of the rheometer. Then the linear viscoelastic region, composite modulus value, as well as changes in slope with time of the composite modulus and phase angle of various hydrogel matrix were analyzed in detail. The results showed that the stability of matrix was mainly determined by hydrogel frame; only in acidic environment, the cross-linking reaction between cross-linker and hydrogel frame can occur; elasticity of matrix can be decreased by organic acid and the effect level was related to the ratio of the number of carboxyl and hydroxyl (-COO(-)/-OH) in adjusters: if the ratio was not equal, the higher -COO(-)/-OH in adjusters would be the less elasticity of matrix decreased; the cross-linking speed of matrix was determined by adjuster, the cross-linking speed of matrix contain different adjusters was ranged in following order: matrix containing tartaric acid > matrix containing lactic acid > matrix containing malic acid > matrix containing citric acid; the cross-linking speed of matrix was not uniform in the whole cross-linking process.

Objective To explore the effectiveness and safety of vaginal paravaginal repair(VPVR) plus vaginal bridge repair in the treatment of female pelvic organ prolapse (POP). Methods Sixty-five patients with different defects of pelvic floor underwent VPVR or plus vaginal bridge repair for posterior vaginal wall. Patients were followed up after operation. The cure rate was estimated subjectively and objectively. The patients' quality of life was evaluated by the pelvic floor distress inventory short form 20 (PFDI-20). Results All 65 cases were treated by vaginal hysterectomy and anterior vaginal repair, in which there were 33 cases underwent VPVR while 32 cases underwent VPVR plus middle area repair. Forty concomitant procedures for vaginal bridge repair were also performed. The average operative time was (110.00±20.12) min and blood loss was (119.52±45.33) ml. The symptom of stress urinary incontinence of 25 cases significantly released after operation. Four incision recovery delayed and there were no other complicatious occurred. Patients were followed up for 6-29 months,the objective cure rate was 100.00% (65/65) and subjective cure rate was 92.31%(60/65), and 58 cases (89.23%)improved significantly with the quality of life comparing with that of pre-operation by completing PFDI-20 (P<0.01). Conclusions It is an effective and safe procedure for VPVR plus vaginal bridge repair to correct median to severe anterior vaginal prolapse and posterior vaginal wall prolapse. More clinical trials are needed to evaluate their long-term outcome.

Objective To evaluate the clinical and endocrine effectiveness of different laser doses for ultrasound-guided transvaginal ovarian interstitial laser treatment in patients with polyeystic ovary syndrome (PCOS). Methods Between January 2005 and July 2007, 56 women with clomifene citrate-resistant PCOS selected from the patients who were referred to Shenzhen Maternity and Child Healthcare Hospital with a request for fertility underwent ultrasound-guided transvaginal ovarian interstitial laser treatment. All subjects were randomly divided into four groups of A, B, C and D. In group A, one coagulation point per ovary was done and group B, two points; group C, three points; group D, four to five points. The size of each point was about 10 mm in diameter (the electrical laser was projected persistently for 1-3 min with a power of 3-5 W) . The serum sexual hormone level, ovulation rate and pregnancy rate within six postoperative months were compared among the four groups. Results (1) The spontaneous ovulation rates of groups A (0) and B (21%) within six postoperative months were significantly lower than groups C (71%, P <0.05) and D (79%, P<0.01). The accumulative pregnancy rates of group C (43%) and D(36%) for six postoperative months were significantly higher than group A(0; P <0.01 ,P <0.05). Although they were also higher than that of group B, no statistical significance was found (P>0.05). (2) No statistically significant differences were found among four groups when various preoperative hormone values were compared (P>0.05). The mean serum luteinizing hormone (LH), testosterone level and LH/ follicle stimulating hormone (FSH) ratio was significantly lower postoperatively in groups C [(6.3±2. 6) U/L, (2.2±0.7) nmol/L, 1.1±0.3] and D [(5.8±2.5) U/L, (2.1±0.4) nmol/L, 1.0±0.4] than in groups A [(11.9±3.1)U/L,(3.9±1.6)nmol/L,2.1±0.5] and B [(10.4±3.9)U/L,(3.3±1.1) nmol/L, 2. 0±0.6],respectively(P<0.05). The mean LH, testosterone level and LH/FSH ratio reduced more obviously in groups C (42%,39% and 42% ) and D(53% , 40% and 58% ) than in groups A (4%, 9% and 16%)and B(11%, 6% and 5%;P<0. 05). All above-mentioned parameters between groups C and D had no statistical significant difference (P>0.05). Conclusions One and two intracvarian laser coagulation points per ovary are associated with poor results. Three points per ovary seem to represent the plateau of effective dose for the ovarian interstitial laser treatment. Increasing the dose above it does not improve the outcome.

The experience of various countries proves that the hierarchical diagnosis and treatment model can lead to reasonable resources allocation and utilization, however, the waste of China''s disordered treatment model has not been estimated.Nowadays, it is very important to establish a hierarchical diagnosis and treatment system during China''s healthcare system reform.Therefore, it is necessary to estimate the benefit the reform may bring.We take Zhejiang Province as an example, and adopted the system dynamics model to build the health delivery system, to emulate the hierarchical diagnosis and treatment model and the disordered model, and to evaluate the benefit.Results showed that if first option at the primary health institutions increased 10%, it could save 0.251 billion yuan, and if increased 15%, it could save 0.39 billion yuan.If the first option at the primary health institution reached 72.35% and the treatment in county reached 90%, the outpatient in tertiary hospital could reduce by 13 million, and those in primary healthcare institutions could increase by 74 million yuan.The direct healthcare cost could reduce 3.016 billion Yuan.
