Aiming at molybdate and boron deficient acid purple soil from main peanut cultivated areas in Sichuan,and Mo and B requirement of peanut growth,the feasibility of Co-inoculum of peanut Bradyrhizobium and molybdate and boron was studied.The tolerance to molybdate and boron of the tested strains Spr2-9,Spr4-5 was inspected.The result indicated that the two tested strains could tolerate higher concentration of molybdate than that of boron.The compound inoculum of Bradyrhizobial strain and trace element Mo was developed.The optimum concentration of Mo was 0.4%.

Objective To observe the effect of raloxifene, a selective estrogen receptor modulator, on osteoporosis in the osteoprotegerin (OPG) gene knock-out female and male mice. Methods Two groups of OPG gene deficient (OPG-/-) female and male mice, 20 mice in each group, were assigned to raloxifene-treated (3 mg The effect of raloxifene was evaluated by comparing the values of bone mineral density (BMD) , bone strength,histomorphometric measurement and osteoclast number between the raloxifene treated group and placebo group.Results As compared with placebo group osteoporotic manifestations were improved in OPG-/- female mice treated with raloxifene orally. BMD was increased both in lumbar vertebrae (P<0.05) and femurs (P<0.01).Bone strength was measured in femurs by three-point bending test and vertebrae by stress test. Results showed that ultimate load, ultimate stress and Young's modulus were increased both at lumbar and femur bone, suggesting decreased risk of fracture. Tartrate-resistant acid phosphatase, a marker enzyme of osteoclasts, was detected, and the number of osteoclasts declined significantly after the treatment of raloxifene. At the same time, results of histomorphometric measurements indicated that bone trabecular volume was increased and bone formation rate decreased from(8.05±4.02)mm3·mm-2·year-1 to (5.48±1.89)mm3·mm-2· year-1(P＜0.05).These findings were found in the group of OPG-/- female mice treated with reloxifene but not in male mice. Conclusions Raloxifene is effective in treating osteoporosis in female OPG-/- mice, indicating that its action is at least in part independent of OPG gene. But it is ineffective in male OPG-/- mice.

Objective: To observe the improving effect of muscle regions of meridians needling method on the upper limb function in children with cerebral palsy of spastic hemiplegic type. Methods: A total of 100 children with cerebral palsy of spastic hemiplegia type were divided into a treatment group and a control group according to the visiting sequence, with 50 cases in each group. The control group was treated with conventional rehabilitation plus conventional acupuncture treatment. The treatment group was treated with conventional rehabilitation plus muscle regions of meridians needling method. The electromyography (EMG) signal values of triceps brachii and pronator teres were detected before treatment, and 3 months and 6 months after treatment. The clinical efficacy was evaluated by Peabody developmental motor scale-fine motor (PDMS-FM) and fine motor function measure (FMFM). Results: Three and six months after treatment, the EMG signal values of triceps brachii and pronator teres, grasping scores and visual-motor integrated scores of PDMS-FM and the FMFM scores in both groups increased to varying degrees compared with the same group before treatment, and the intra-group differences were all statistically significant (all P<0.05). Six months after treatment, the results of the above three items in the treatment group were all better than those in the control group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Muscle regions of meridians needling method added on the basis of conventional rehabilitation can effectively reduce the muscle tone of upper limb and enhance the muscle strength, and improve the upper limb function in children with cerebral palsy of spastic hemiplegia type. The efficacy is superior to that of the conventional rehabilitation plus conventional acupuncture treatment.

Objective:To observe the clinical efficacy of needling thirteen ghost acupoints for children with autism spectrum disorder. Methods:A total of 90 cases with autism spectrum disorder (ASD) aged between 2 and 6 years were randomly allocated into 2 groups by random number table. The control group (n=45) received routine rehabilitative training, and the treatment group (n=45) received acupuncture at thirteen ghost acupoints plus routine rehabilitative training. The Beijing Gesell developmental (Gesell) scale and autism behavior checklist (ABC) were used to assess the intellectual, language and behavior development before and 3 months after the treatment. Results:After the treatment, the total effective rate in the treatment group was 82.2%, versus 55.6% in the control group, showing a statistical significance (P<0.05). As for the scores of social, emotional and language in Gesell scale, there were significant intra-group differences in the treatment group (allP<0.05), and all the five subscales in the Gesell scale in the treatment group were significantly better than those in the control group (allP<0.05). As for the scores of ABC, there were significant intra-group differences in the treatment group (P<0.05), and the scores in the treatment group were significantly better than those in the control group (allP<0.05). Conclusion: Rehabilitation training plus acupuncture at thirteen ghost acupoints can significantly improve the intellectual, language and abnormal behavior in autism spectrum disorder children.

The change in plasma ghrelin level after 4-and 12-week adjunctive therapy of rosiglitazones in type 2 diabetic patients inadequately controlled by sulphonylurea alone was observed and the relation between ghrelin and insulin resistance was analysed.The results showed that rosiglitazones significantly increased circulating ghrelin level and obviously decreased insulin resistance index after therapy for 4 and 12 weeks in type 2 diabetic patients.

OBJECTIVETo observe the clinical effect of Dihuang Zhixue Capsule (DZC, a Chinese preparation for cooling blood and dispelling toxic substances) in the treatment of childhood refractory idiopathic thrombocytopenic purpura (RITP), with cyclosporin A (CsA) used as the control.

METHODSForty-one children of RITP were randomized into the treated group and the control group. The 21 patients in the treated group were orally given 2 to 3 DZC capsules each time, thrice a day and the 20 in the control group were given 3 mg/kg CsA per day, with 3 months as one therapeutic course. The therapeutic efficacy, platelet count and adverse reaction in the two groups were compared at the end of the course.

RESULTS(1) In the treated group, 1 (4.8%) patient was evaluated as cured, 3 (14.3%) as markedly effective, 5 (23.8%) as effective, 5 (23.8%) as improved, 7 (33.3%) as ineffective, with the total effective rate being 66.7%; while in the control group, the corresponding numbers were 0, 2 (10.0%), 2 (10.0%), 3 (15.0%), 13 (65.0%) and 35.0%, respectively, showing statistical significance in difference between the total effective rates of the two groups (xi(2)=4.11, P=0.0426). (2) As compared with the baseline, the platelet count increased in both groups after 2 months' treatment (P<0.05). After 3 months' treatment, the platelet count was higher in the treated group than in the control group (P<0.05). (3) The improvement of hemorrhage in the treated group after 8 weeks' treatment was better than that in the control group (P<0.05). (4) No apparent adverse reaction was observed in the treated group, while in the control group, hirsutism was shown in 15 cases; gingival hyperplasia in 10; digestive reaction in 5, liver function impairment in 5, hypertension in 2 and renal impairment in 2.

CONCLUSIONThe therapeutic efficacy of DZC is better than that of CsA, and DZC shows good compliance but brings no obvious adverse reaction.

OBJECTIVETo understand the sexual physiology and psychology of male college students and to provide schools, families and the society with reference for the sexual physiological and psychological education among college students as well as for the diagnosis and treatment of their sexual psychological disorders in Jiangsu.

METHODSAn investigation was conducted by using a questionnaire on sexual physiology and psychology among randomly selected 3786 male college students from 18 universities in Jiangsu.

RESULTSAs regards sexual education, 5.49% of the subjects were satisfied with their schools, 78.18% wanted it to be strengthened and 68.36% obtained their sexual knowledge from the internet. Concerning sexual physiology, 68.78% experienced their first spermatorrhea at the age of 12-15. As for sexual psychology, 85.79% loved a certain female inwardly, and 70.99% experienced love affairs. With regard to sexual activity, 25.54% had sexual experience.

CONCLUSIONCollege students nowadays are relatively open in sexual ideology, immature in sexual psychology and lacking in sexual knowledge, while schools are inefficient in sexual education. Their sexual health calls for joint attention from schools, families and the society, particularly schools, which need to establish special offices for research and education on sexual health.

PURPOSE: Insufficient sensitivity and specificity prevent the use of most existing biomarkers for early detection of breast cancer. Recently, it was reported that serum microRNAs (miRNAs) may be potential biomarkers in many cancer diseases. In this study, we investigated whether serum levels of 5 miRNAs including miR-21, miR-125b, miR-145, miR-155, and miR-365 could discriminate breast cancer patients and healthy controls. METHODS: Serum levels of miRNAs were measured by using quantitative real-time polymerase chain reaction in 99 breast cancer patients and 21 healthy controls. The abundance change of serum miRNAs were also evaluated following surgical resection in 20 breast cancer patients. Receiver operating characteristic (ROC) curve analysis was performed to assess the sensitivity and specificity of miRNAs as diagnostic biomarkers. RESULTS: Serum levels of miR-21 and miR-155 was significantly higher, while miR-365 was significantly lower in breast cancer as compared with healthy controls. The serum levels of miR-21 and miR-155 significantly decreased following surgical resection. Additionally, the serum level of miR-155 at stages I and II was significantly higher compared to stage III. The serum miR-145 level was remarkably higher in progesterone receptor (PR)-positive patients than PR-negative. The positivity of miR-21, miR-155, and miR-365 was high compared to CA 153 and CEA in breast cancer. ROC curve analyses of a combination of miR-21, miR-155, and miR-365 yielded much higher area under curve and enhanced sensitivity and specificity in comparison to each miRNA alone. CONCLUSION: The combination of serum miR-21/miR-155/miR-365 may potentially serve as a sensitive and specific biomarker that enables differentiation of breast cancer from healthy controls.

OBJECTIVETo study the effect of length of cervical anterior fusion on adjacent levels by Biomechanical test.

METHODSSix fresh-frozen human cervical specimens were used in this study. The specimens were tested in flexion, extension, bending and rotation on a spine 3D test system. The specimens were tested intact and then underwent a single-level anterior cervical discectomy and fusion (ACDF) at the C4-5 first, a double-level fusion at the C4-6, and finally extended to triple-level at the C4-7, Based on a hybrid test method. Changes in overall range of motion (ROM), segmental motion and facet joints pressure during flexion, extension, bending and rotation were measured and statistically analyzed.

RESULTSThe overall ROM of the entire spinal construct decreased progressively as the single-level fixation extending to 2-level and 3-level (P < 0.05). A progressive increase in ROM above (C3-4) the fused motion segment units (MSUs) was found during flexion, extension and bending (P < 0.05). In bending and extension, a same result was recorded on the average pressure and max pressure of C3-4 facet joints (P < 0.05).

CONCLUSIONSThis study has demonstrated that the biomechanics at adjacent levels to a cervical spine fusion are altered and that there was progressively increased adjacent segment motion and stress as a single-level ACDF extended to a 3-level fusion, which might lead to the acceleration of adjacent segment degeneration.
