Objective To observe the clinical effect of Xisui Huangu Formula combined with technetium [99Tc] methylenediphosphonate injection in the treatment of avascular necrosis of femoral head (ANFH). Methods A total of 73 patients were randomly divided into treatment group (37 cases) and control group (36 cases). The control group was given conventional western medicine treatment, while the treatment group was given Xisui Huangu Formula on the basis of conventional western medicine treatment. Clinical symptoms and joint function of the two groups were observed before and after treatment, and the clinical effects were compared. Results In the treatment group, 17 cases were cured, 17 cases improved, 3 cases were unrecovered, and the effective rate was 91.89%. In the control group, 4 cases were cured, 25 cases improved, 7 cases were unrecovered, and the effective rate was 80.56%. The difference was statistically significant between the two groups (P<0.05). Improvement of joint pain, lameness, dysfunction, and joint function in the treatment group were better than those in the control group (P<0.05). Conclusion Xisui Huangu Formula can significantly improve clinical symptoms of ANFH. Integrated traditional Chinese and Western medicine therapy is helpful to alleviate ANFH disease progression.

Objectives To optimize the curriculum for better education quality. Methods By literature review, the curriculum of the bio-medical English program of Peking University was summa-rized. Interviews were conducted on 8 sophomores of the program based on convenience sampling for their concerns over the curriculum and a questionnalre was designed based on such concerns. Ques-tionnalre survey was used for the remarks and suggestions of the 129 graduates of year 2002, 2003 and 2004 on the curriculum, with 79 valid questionnalres collected and the data analyzed by Microsoft Excel. Results Respectively 64 (81.02%), 52 (65.82%), 53 (67.09%) respondents believe the se-quence, duration and connection of the English courses are appropriate and 65 (82.27%), 46 (58.22%), 50 (63.29%) respondents believe the sequence, duration and connection of the medical courses are appropriate. 63 (81.77%) respondents hoped that they could do experiments in the medical courses, but 18 of them (23.08%) worried that the experiments would make the curriculum more tense. 71 (89.97%) respondents thought that the internship at hospital in the curriculum was conducive to better understanding of medical course contents . Suggestions on the improvement of the curriculum were also made by respondents. Conclusions The curriculum could be further optimized, especially on the connection between different courses, although most of the respondents by and large believe that the curriculum of the program is rational and hold positive attitude towards the internship in hospital and experiments in the curriculum.

Objective To investigate the expression of tissue factor and explore its clinical significances in pulmonary artery after acute pulmonary thromboembolism.Methods Thirty-four Japanese white rabbits (Level Ⅱ animals) were randomly (random number) assigned into four groups:group A (specimen of pulmonary artery was taken 3 hours after pulmonary embolism,n =8),group B (specimen of pulmonary artery was taken 8 hours after pulmonary embolism,n =8),group C (specimen of pulmonary artery was taken 24 hours after pulmonary embolism,n =8) and control group (pseudo-operations were carried out without injecting autologous blood clots,n =10).The animal model of pulmonary thromboembolism was established by injecting autologous blood clots into jugular vein through a 5F catheter and confirmed by digital subtraction angiography.The mRNA expression of TF in different parts of pulmonary artery was assayed by RT-PCR.The q test was utilized if there was a significant difference in a given continuous variable among three groups analyzed by ANOVA.Results The TF expression in the specimen adjacentto emboli was stable at 3 h,8 h or 24 hours after embolism.The mRNA expression of TF at 3 h and 8 h after embolism was lower in specimen taken from distal-end of morbid pulmonary artery than those adjacent to emboli.While at 24 hours after embolism,there were similar mRNA expressions in specimen either adjacent or distal to emboli.Conclusions The high expression of tissue factor in pulmonary artery tissue adjacent to emboli could lead to locally increased coagulation activity,indicating the necessity of initiating anti-coagulation treatment as soon as possible after acute pulmonary embolism.

Objective To observe the therapeutic effects of electrical stimulation of pelvic floor muscles on urinary incontinence (UI) in patients with incomplete spinal cord injury (ISCI). Methods Seven patients (5 males and 2 females; average age: 32.5 years; average duration after injury: 7.5 months) with ISCI were treated with ESPFM applied on rectum (for male) or vagina (for female) for 30～45 min,once a day, 5 days a week for (2～3) months. The rate of success on stopping using catheters and the frequency and amount of urination were observed during treatment. Results Catheters were taken out successfully from all patients 2～3 weeks after treatment. Five out of the 7 patients had more self-control of urination than incontinence after 8 weeks of treatment though there was no significant difference in the amount of the urination. Conclusion ESPFM might improve the function of urinary bladder in patients with incomplete spinal cord injury.

Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

Objective To investigate the characteristics and relationship of cognitive function and resting state functional magnetic resonance imaging(fMRI) amplitude of low-frequency fluctuations (ALFF)in childhood and adolescence-first-onset obsessive-compulsive disorder(OCD).Methods Twenty-four childhood and adolescence-first-onset OCD patients (patient group) and thirty-three age/gender/education-matched healthy controls (healthy control group) were enrolled in this study.The participants' cognitive function was tested with trail making test (TMT),symbol coding,Hopkins verbal learning test-revised (HVLT-R),brief visuospatial memory test-revised (BVMT-R),verbal fluency test (VF),digital span test,maze test and Stroop test.Then a resting-state fMRI scan was conducted for each participant.Amplitude of low-frequency fluctuation approach was used to explore the differences of resting-state brain function between patients and controls,and analyze the significant brain regions by adopting t test.The cognitive functions of patients and healthy control group in the significant brain regions were compared by using Pearson correlation analysis.Results The patient group had lower scores than healthy control group in symbol coding,BVMT-R and digital span test,and the differences were statistically significant [(45.24 ± 10.32)scores vs.(56.85 ± 9.57) scores,(21.94 ± 6.99) scores vs.(30.58 ± 3.92) scores,(64.06 ± 20.00) scores vs.(78.03 ±18.08) scores;t =3.96,4.90,2.50;all P ＜ 0.05].Corrected by Alphasim,patient group showed significantly increased ALFF in the left and fight temporal lobe,left and fight posterior lobe of cerebellum,right middle temporal gyrus,but ALFF decreased in the area of left and right lenticula,left putamen compared with the healthy control group (all P ＜ 0.05).The patients group showed that TMT scores were positively correlated with the value of ALFF in the right temporal lobe (r =0.67),and color scores were positively correlated with the value of ALFF in the right middle temporal gyrus (r =0.53),but colour scores were negatively correlated with the value of ALFF in the right tcmporal lobe (r =-0.54);the healthy control group showed that BVMT-R and digital span test scores were positively correlated with the value of ALFF in the left temporal lobe (r =0.47,0.41),but digital span test scores were negatively correlated with the value of ALFF in the right temporal lobe (r =-0.49),and colour scores were negatively correlated with the value of ALFF in the left temporal lobe (r =-0.35),while word and color-word scores were negatively correlated with the value of ALFF in the right middle temporal gyrus (r =-0.39,-0.36);the correlation coefficient above had statistical significance (all P ＜ 0.05).Conclusions The childhood and adolescence-first-onset OCD patients had cognitive impairment,including speed of processing,visual learning and memory,working memory;and the patients showed abnormal spontaneous neural activity at some brain regions.The cognitive dysfunction may be associated with abnormal spontaneous neuronal activity in childhood and adolescence-first-onset OCD.

The first genetic linkage map of Salvia miltiorrhiza was constructed in 94 F1 individuals from an intraspecific cross by using simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers. A total of 93 marker loci in the linkage map, consisting of 53 SSR, 38 SRAP and 2 ISSR locus were made up of eight linkage groups, covered a total length of 400.1 cm with an average distance of 4.3 cm per marker. The length of linkage groups varied from 3.3 -132 cm and each of them included 2-23 markers, separately. The result will provide important basis for QTL mapping, map-based cloning and association studies for commercially important traits in S. miltiorrhiza.
