OBJECTIVETo compare the differences in the therapeutic effect on irritable bowel syndrome (IBS) between acupuncture at Tianshu (ST 25) and Dachangshu (BL 25) and western medication with Trimebutine Maleate.
METHODSForty cases were divided randomly into an acupuncture group and a western medication group, 20 cases in each one. In acupuncture group, acupuncture was applied to Tianshu (ST 25) and Dachangshu (BL 25). Ziwu Daojiu needling technique was adopted, once daily. In western medication group, Trimebutine Maleate capsule was administered, 2 capsules in each time, 3 times per day. The assessment on the therapeutic effect was performed in 4 weeks of treatment in two groups.
RESULTSAs compared with those before treatment, the time of abdominal pain, the frequency of abdominal pain, the morbidity of abnormal stool appearance, the morbidity of defecation abnormality, the morbidity of mucus stool and the score of bloating or abdominal pain on bowel movement were all reduced after treatment in two groups (all P < 0.01). The results in acupuncture group were much more significant than those in western medication group (the total score: 16.70 +/- 2.40 vs 15.70 +/- 3.01, P < 0.01). The total effective rate in acupuncture group was 95.0% (19/20), which was superior to that of 70.0% (14/20) in western medication group (P < 0.05).
CONCLUSIONAcupuncture at Tianshu (ST 25) and Dachangshu (BL 25) may remarkably relieve the clinical symptoms of IBS and its efficacy is superior to that of oral medication with Trimebutine Maleate.

OBJECTIVETo compare the effect of reinforcing Shen method (RSM) and activating blood method (ABM) in treating osteoarthritis (OA) at the molecular level.
METHODSThe physical and chemical characteristics of components from respective recipes of RSM and ABM, and network features of component-target interaction network were analyzed by computer simulation methods including chemical space, molecular docking, and biological network, etc.
RESULTSThe chemical components of RSM and ABM were scarcely scattered with larger overlapping. Among established networks, the distribution of network features was partially similar in RSM and ABM. The average target number correlated with each component was 1.86 in RSM and 2.11 in ABM respectively. Each average target number was respectively correlated with 4.46 compounds and 3.93 compounds, reflecting multi-component and multi-target actions.
CONCLUSIONComputer simulation could intuitively trace out similarities and differences of two different methods and their interaction with targets, which revealed that the compatibility of RSM and ABM could have broader protein targets and potential synergism at the molecular level.

AlM: To investigate the association between the degree of anterioruveitis and related factors including inflammatory markers as well as sacroiliac joint imaging in patients with ankylosing spondylitis ( AS) .
METHODS: Anterior changes evaluated by slit lamp, erythrocyte sedimentation rate ( ESR ) , C - reactive protein ( CRP ) and magnetic resonance imaging of 55 cases with AS associateduveitis were retrospectively analyzed. A modified endotoxin-induced uveitis ( ElU ) clinical standard was used for uveitis grading. SPARCC sacroiliac scoring was used to evaluate bone edema of sacroiliac joint. The correlation between the degree of uveitis and sacroiliitis was assessed.
RESULTS: ln the 55 patients with AS, ElU grading scored 2-10, and SPARCC index scored 0-22. Further analysis showed that the severity of uveitis was significantly correlated with ESR (r=0. 869, P<0. 001) and CRP (r=0. 485, P<0. 001). The degree of anterior uveitis in AS patients was not correlated with inflammation of sacroiliac joint (r=0. 237, P=0. 081).
CONCLUSlON: Local autoimmunity of uveitis and sacroiliac joint inflammation with subsequent bone formation in AS might be mutually independent processes.

Objective To apply a simple fixator to salivary gland scintigraphy to evaluate its effect on body position movement. Methods Totally 30 female patients complaining xerostomia were randomly and equally divided into a conventional scan group and a simple fixator group,who were injected with Technetium Tc-99m Pertechnetate intravenously. In the conventional scan group the patients had their necks fixed with the bracket and cushion,while in the other group the fixation was executed with the single fixator. SPECT imager was used for dynamic salivary gland scintigraphy, and two nuclear medicine physicians evaluated the maximum shift of the parotid gland along left-right(X)and head-foot(Y)axes in series of dynamic images. SPSS 16.0 software was used for data analysis. Results In the conventional scan group the maximum shift was(6.6±4.6)mm at X axis and(5.2±3.4)mm at Y axis;in the single fixator group the maximum shift was(3.2± 1.6)mm at X axis and(3.0±1.3)mm at Y axis.There were significant differences between the maximum shifts in the two groups (P=0.012,X axis;P=0.027,Y axis).Conclusion The single fixator assists in salivary gland scintigraphy,and alleviates the body position movement during dynamic acquisition and provides data support for functional parameter calculation and result determination.

Objective To evaluate the cardiopulmonary exercise capacity in patients with essential hypertension (EH) complicating with or without left ventricular hypertrophy (LVH). Methods Graded maximal exercise test on the bicycle ergometer with respiratory gas analysis were performed in 30 gender and age matched normotensive controls, 40 EH patients without LVH and 30 EH patients with LVH (LVMI 125 g/m2 in males and 120 g/m2 in females). Metabolic equivalents (METs), oxygen uptake(VO2), oxygen uptake to body mass ratio (VO2/kg) and oxygen uptake to heart beat ratio (VO2/HR) at time of reaching anaerobic threshold (AT) and at maximal oxygen uptake (VO2max) were measured and compared. Results METs and VO2/kg were significantly reduced in EH patients with or without LVH compared with controls [ at AT, METs: 3.57±0. 8 and 4. 34±1.47 vs. 5.21±1.45 ; VO2/kg: 12. 38± 2. 85 and 14. 42±4. 33 vs. 18.48±4. 52, all P < 0. 01 ;at VO2max, METs:4.94±1.24 and 5. 90±1.51 vs. 6.96±1.85;VO2/kg:(17.20±4.34) ml·min-1·kg-1and (20.41±4.59 )ml · min-1·kg-1 vs. (24. 04±5.21) ml·min-1·kg-1, all P < 0. 01 ]. METs and VO2/kg at both time points were also significantly reduced in EH patients with LVH compared EH patients without LVH ( all P < 0. 05). The lower VO2/kg in hypertensive patients was significantly correlated to higher LVMI ( P < 0. 05 ). Conclusions Cardiopulmonary exercise capacity was reduced in hypertensive patients, especially in hypertensive patients with LVH.

WRKY transcription factor is one of the Zinc finger proteins which contains a highly conserved WRKY domain and is a family of the plant-specific transcription factor. The plasmid pET28a-SmWRKY1 harboring Salvia miltiorrhiza WRKY1 (SmWRKY1) gene was successfully transformed and expressed in Escherichia coli BL21 (DE3). The conditions on protein expression of SmWRKY1 in E. coli, including induction duration, temperature, IPTG concentration and the E. coli concentration were optimized. The results showed that the highest protein expression of SmWRKY1 was obtained at 24 hours after the E. coli was cultured in the presence of 0.2 mol x L(-1) IPTG at 20 degrees C with A600 values of 1.0-1.5. This recombinant histidine-tagged protein was expressed at 2.454 g x L(-1) as inclusion body, which was first extracted using urea, and then purified by Ni2+ affinity chromatography and identified by SDS-PAGE. The expression of SmWRKY1 in E. coli was further confirmed by western blotting analysis.

Objective To study the mechanism of marcosomia by investigating insulin-like growth factor 2(IGF_2)imprinting status,expression level and the promoter usage in the placenta of macrosomia. Methods We selected heterozygous cases for Apa Ⅰ polymorphism in exon 9 of IGF_2 gene and then analyzed its imprinting status in 168 placentas of macrosomia and normal pregnancies.IGF_2 transcription levels and promoter usages in macrosomic and normal placenta were evaluated by using semi-quantitative RT- PCR assay.Results Thirty specimens of macrosomic placenta and 30 of normal placenta were identified as heterozygous for IGF_2.All of the heterozygous specimens showed maintenance of imprinting.The expression of placental IGF_2 mRNA(2.2?1.2)was significantly higher in macrosomia than that of normal weight group (1.6?0.6,P 0.05).Conclusion It is possible that over expression of IGF_2 in placenta contributes to macrosomia while the promoter usage and imprinting status are not associated with macrosomia.

AIMTo investigate the stepwise development and germ cell gene expression in allografted neonatal mouse testes and the differentiation of immature human testicular cells in xenografted human testes.
METHODSImmunodeficient nude mice were used as hosts for allografting of neonatal mouse testes and xenografting of human fetal testicular tissues. Stepwise development and stage-specific gene expression of germ cells in allografts were systematically evaluated and parallel compared with those in intact mice by periodically monitoring the graft status with measurement of graft weight, histological analysis and determination of five stage-specific genes. Human testicular tissues from 20 and 26 weeks fetuses were used for the xenografting study. Histological analysis of xenografts was performed 116 and 135 d after the grafting procedure.
RESULTSIn the allografting study, progressive increase in tissue volume and weight as well as in tubule diameter in grafts was observed; the appearance time of various germ cells in seminiferous tubules, including spermatogonia, spermatocytes, round and elongate spermatids and sperm, was comparable with that in intact donors; the initiation of gene transcription in grafts showed a similar trend as in normal mice. Graft weight ceased to increase after 7-8 weeks and degradation of grafts was observed after 5 weeks with progressive damage to seminiferous epithelium. In the xenografting study using immature human testicular tissues, graft survival and development was indicated by increasing graft weight, Sertoli cells differentiation into advanced stage, germ cells migration and location to the basal lamina and formation of a niche-like structure.
CONCLUSIONThe developmental course and gene expression pattern of germ cells in allografts were similar to those in intact mice. The best time point for retrieval of mouse sperm from grafts was 5-7 weeks after grafting procedure. An accelerated development of immature human testicular cells could be achieved by ectopic xenografting of human testes.

OBJECTIVETo observe the effect of the inducible nitric oxide synthase (iNOS) gene on androgen-independent prostate cancer DU145 cells in vitro.
METHODSThe iNOS gene was transfected into androgen-independent prostate cancer DU145 cells. The positive cells were selected as the transfected group for amplification, and an empty vector (EV) group and a control group were also set. The mRNA transcription of iNOS was analyzed by RT-PCR. The morphological changes of the cells were observed, the effect of iNOS transfection on the cell growth determined using the MTB method, and the apoptosis of DU145 cells detected by flow cytometry, followed by analysis of the effect of NOS inhibitors on the transfected cells.
RESULTSDU145 cells transfected with iNOS secreted significantly more nitric oxide ([272.50 +/- 15.82] micromol/L) than those of the EV and control groups ([122.00 +/- 18.93] micromol/L and [121.00 +/- 6.98] micromol/L) (P < 0.05). The rate of cell apoptosis was markedly enhanced in the transfected group as compared with the EV and control groups ([42.78 +/- 2.01]% vs [30.65 +/- 1.46]% and [28.96 +/- 1.50]%, P < 0.05). MTP test indicated a slower growth of the DU145 cells in the former than in the latter two (P < 0.05). NOS inhibitors enhanced their growth, but with no significance (P > 0.05).
CONCLUSIONDU145 cells transfected with iNOS could secrete high-concentration nitric oxide, induce cell apoptosis, and suppress cell proliferation, which may provide a potentially effective gene therapy for advanced androgen-independent prostate cancer.

OBJECTIVETo explore the efficacy of urethral dilatation with the renal sheath dilator under the ureteroscope in the treatment of male patients with urethrostenosis.
METHODSEighteen male patients with urethrostenosis underwent urethral dilatation with the renal sheath dilator. Under the ureteroscope, a zebra-guide wire was inserted through the stenosed urethra into the bladder and the stenosis was gradually dilated with the renal sheath dilator, followed by placing a Foley catheter of proper size for 1-4 weeks. For children, the renal sheath dilator was selected according to their age, while for adults, metal dilators (> or = F20) were used following dilatation with the F18 renal sheath dilator. All the patients were followed up for 6-24 months.
RESULTSThe operation was successfully performed in all the 18 cases, with no urethral false passage, urethral perforation or urethra tearing. Sixteen of the patients were cured, and the other 2 received urethroplasty for stenosis recurrence. The maximum flow rate was increased to 13.6-30.2 (18.1 +/- 3.5) mL/s after the operation.
CONCLUSIONUrethral dilatation with the renal sheath dilator under the ureteroscope is a simple, safe and effective method for the treatment of urethrostenosis.
