Objective To establish a method for rapidly detecting the G-protein ?3 subunit (GNB3) 825 site single nucleotide polymorphism (SNP) and to analyse the relationship between GNB3 825 site gene SNP and obesity. Methods The real-time fluorescent PCR was employed to analyse the GNB3 825 site gene SNP of 420 samples from 21 provinces and the the frequencies of genotypes were compared with those detected by gene sequencing. GNB3 825 site genotype, body weight, body mass index (BMI) and fat content were examined from 207 subjects and the correlation between GNB3 825 site gene SNP and obesity was analysed. Results The result by real-time fluorescent PCR showed that the frequencies of 825T and 825C haploid were 46.90% and 53.10%, respectively, and the frequencies of 825TT, 825TC and 825CC genotype were 22.38%, 51.42% and 28.10%, respectively, with no other genotype detected, which was consistent with the result by gene sequencing. BMI and fat content were significantly higher in subjects with GNB3 825TT than in subjects with other genotypes. Body weight was much higher in subjects with GNB3 825TT genotype than in subjects with 825CC genotype, but not significantly different with 825CT genotype. Conclusion A new rapid method for the detection of GNB3 825 site SNP has been successfully established. There existed significant correlation between GNB3 825TT genotype and obesity.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

OBJECTIVETo evalute the efficacy of high-resolution CT(HRCT) in differential diagnosis and treatment of chronic suppurative otitis media and cholesteatoma otitis media by soft-tissue shadows.

METHODSHRCT scanning was performed in 120 cases, 153 ears, with chronic otitis suppurative media and cholesteatoma otitis media, of which original data were processed with multi-planar reconstruction (MPR) and maximum intensity projection (MIP), the characteristics of the soft-tissue shadows' growth, window width or window leveling and bony destruction were respectively observed, as well as compared with the surgery findings.

RESULTSIn 120 patients (153 ears), 109 ears were diagnosed as cholesteatoma otitis media, and 44 ears were diagnosed as chronic suppurative otitis media, among which 33 ears had granulation tissue and 11 ears had secretion. One hundred and seven ears were postoperatively diagnosed as cholesteatoma otitis media, among which 25 ears had granulation tissue. Among 46 ears of chronic suppurative otitis media, 35 ears had granulation tissue, and only 11 ears had secretion. A 98.6% diagnostic accuracy can be reached with HRCT in diagnosing cholesteatoma otitis media and chronic suppurative otitis media. The Youden's index was 0.98, 0.98 and 1.00 respectively with HRCT in diagnosing cholesteatoma, granulation tissue and secretion.

CONCLUSIONSCombination of the three different imaging methods, axial images, coronal MPR images and MIP images, can improve the efficacy of the HRCT diagnosis and definite chronic otitis media, which can be routinely used for surgery plan.

OBJECTIVETo study the effects of Erlong Zuoci Pill (, ELZCP) and its disassembled: prescriptions on gentamicin (GM)-induced ototoxicity model in vitro.

METHODSAfter the spiral organ of cochleae: of newborn mice (postnatal days: 2-3) cultured for 24 h, GM alone or combined with water extracting-alcohol precipitating solution of ELZCP or with its disassembled prescriptions was added. Hair cells were observed under a fluorescence microscope after TRITC-phalloidin staining, and the cochlear hair cell loss rate was calculated by counting the whole cochlear hair cells and analyzed by whole cochlear hair cells analyzing software.

RESULTSGM induced cochlear outer hair cells (OHCs) and inner hair cells (IHCs) injuries in a dose-dependent manner, and they were significantly different as compared with those in the normal control group (P<0.05, P<0.01). ELZCP at the concentration of 0.003-3 mg/mL could decrease the hair cells loss induced by the 0.3 mmol/L GM (P<0.05, P<0.01), the effects was in a dose-dependent manner, and the concentration of 0.3 mg/mL showed the optimal protective effect. For the ELZCP disassembled prescriptions, Liuwei-Dihuang could decrease OHC loss rate than that in the 0.3 mmol/L GM model group (P<0.05), but the OHC loss rate was still higher than that in the ELZCP group (P<0.01), which indicated that the protective effect of hair cells by Liuwei-Dihuang was not better than that of ELZCP. Poria decreased OHC loss rate from 72.1 % +/-3.7 % to 58.8 %+/- 8.2 % (P<0.05).

CONCLUSIONSELZCP could play a role in antagonizing the injury of cochlear hair cells induced by GM ototoxicity,: and its disassembled prescriptions, Liuwei-Dihuang was the main component to protect the cochlear hair cells from GM-induced ototoxicity, and Magnetitum combined with Radix Bupleurui could strengthen the action of the whole prescription; Poria could reduce GM-induced OHC loss.

Estrogen receptor alpha (ERalpha) has been a primary target of treatment as well as a prognostic indicator for breast cancer. The level of human X-box binding protein 1 (XBP-1) mRNA was related with that of ERalpha in breast tumors and was over-expressed in some breast tumors. These previous studies suggested that XBP-1 may interact with ERalpha. XBP-1 has two isoforms, XBP-1S and XBP-1U, as the result of unique splicing. GST pull-down assay showed that both XBP-1S and XBP-1U bound to ERalpha in vitro. The binding of XBP-1S to ERalpha was stronger than that of XBP-1U to ERalpha. Co-immunoprecipitation revealed that the binding was in a ligand-independent manner. XBP-1S and XBP-1U interacted with the region of ERalpha that contains a DNA-binding domain. The ERalpha-interacting regions on XBP-1S and XBP-1U have been mapped to two regions, the N-terminal basic region leucine zipper domain (bzip) and the C-terminal activation domain. These findings suggest that XBP-1S and XBP-1U may participate in ERalpha signaling pathway through the mediation of ERalpha.

Objective To evaluate clinical significance of monitoring noninvasive intracranial pressure (NICP) and cerebral perfusion pressure (CPP) in treatment of patients with hypertensive intracerebral hemorrhage. Methods This clinical randomized controlled trial enrolled 120 patients with hypertensive intracerebral hemorrhage who had sought medical treatment in our department from June 2008 through May 2010. They were randomized equally into a monitoring group where NICP and CPP were continuously monitored before and after operation and a non-monitoring group where no monitoring of NICP and CPP was performed. Results In the monitoring group,increased NICP and decreased CPP were shown in 50 patients and only 10 patients were shown with normal NICP (＜26.6mmHg) and CPP (＞ 124.3 mm Hg). The abnormal NICP and CPP continuously monitored were treated with specific interventions like further operation or medication. In the non-monitoring group,patients received only conventional treatments.According to the Glasgow Outcome Scale (GOS), 31 patients (51.7％) had good recovery,20 (33.3％) were moderately disabled,5 (8.3％) severely disabled and 4 (6.7％) dead in the monitoring group while 23 (38.3％) patients had good recovery,18 (30.0％)were moderately disabled,10 (16.7％) severely disabled and 9 (15.0％) dead in the non-monitoring group.The outcomes of the monitoring group were significantly better than those of the non-monitoring group (P＜0.05). Conclusion Continuous monitoring of NICP and CPP before and after operation should be performed in the treatment of patients with hypertensive intracerebral hemorrhage because it is helpful for clinical medication and reducing complications and mortality as well.

OBJECTIVETo explore the risk factors for relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the measures of prophylaxis and treatment.

METHODSWe summarized the clinical data of 82 patients with hematologic malignancies who were treated in our hospital from August 2003 to December 2008. Factors including age, sex, ABO blood group disparity of donor and recipient as well as the type of donor, status of disease, HLA-match, conditioning regimen, whether or not having developed acute GVHD and chronic GVHD, infusion number of CD34(+) cells, relationship between CMV infection and relapse post-transplantation were considered and analyzed.

RESULTSSingle factor analysis indicated that there were five independent risk factors related with the disease relapse (P < 0.05), including status of disease, time of diagnosis to transplantation, acute graft versus host disease (aGVHD), conditioning regimen, and chronic graft versus host disease (cGVHD). Simultaneously, the type of donor was a substantial factor (P < 0.01), determined by multi-factor Cox regression analysis. Cox regression analysis determined that disease status (OR = 2.58, 95%CI 1.26 - 5.01, P = 0.01), time from diagnosis to treatment (OR = 1.98, 95%CI 1.11 - 3.63, P = 0.025) and cGVHD (OR = 3.74, 95%CI 1.96 - 7.97, P < 0.001) were major factors for relapse of the patients who had undergone transplantation.

CONCLUSIONSRelapse remains the primary cause of failure after allo-HSCT. Status of disease, time from diagnosis to treatment and not cGVHD are the major risk factors. Effective prevention and treatment of relapse after engraftment can improve the efficacy of HSCT.

OBJECTIVETo seek the problems of position, measuring and locating methods of Baliao points (posterior sacral foramina) in modern researches.

METHODSUsing Baliao (eight sacral foramina), Shangliao(BL 31), Ciliao(BL 32), Zhongliao(BL 33), Xialiao(BL 34), Dihoukong (posterior sacral foramina), Dikong (sacral foramina) and Digu(sacrum) as the key words, literature in the database of the CNKI from 1957 to 2012 were re trieved and analyzed.

RESULTSProblems were found in the past researches including limited numbers of relative literature, disunity of the measurement targets, complicated terms of indices, disunity of the starting and ending point of measurement, unclear weight of indices, deviation of results, lacking of combination with clinical practice and variety of locating methods.

CONCLUSIONPosition of Baliao points (eight sacral foramina) are clear. However, the locating methods are blurred and vary a lot. Study on living body has more significance for measurement and researches. Factors of gender, body weight, height and childbearing should also be taken into consideration. Therefore, it is necessary to find a more accurate and easier way of locating.

OBJECTIVEShen Yan Ling Tablet is an innovative compound of traditional Chinese medicine, scientifically prepared with Tripterygium wilfordii, Radix Astragali, and others, with precise efficacy on renal diseases and reduced adverse effects of Tripterygium wilfordii. Based on the Guiding Principles for New Drug Toxicity Research Before Clinical Application, we investigated the long-term toxicity of Shen Yan Ling Tablet and its effect on the reproductive function in rats.

METHODSAccording to the clinical therapeutic dose and the results of the acute toxicity test of Shen Yan Ling Tablet, we equally divided 80 rats (males and females half-and-half) into a low-dose (1.25 g/kg body wt), a medium-dose (2.50 g/kg body wt), a high-dose (5.00 g/kg body wt) and a control group. After a 3-month medication, we conducted standardized long-term toxicity tests and observed the effects of Shen Yan Ling on the serum sexual hormones and epididymal sperm count.

RESULTSAfter 3 months of treatment with Shen Yan Ling, no death occurred, the general status remained unchanged, and the parameters of blood cytology and biochemistry fluctuated within the normal range, without any significant changes (P > 0.05). Some blood parameters, RBC, WBC, HGB, AST and TBIL, showed statistic changes (P < 0.05), but with no clinical significance. There were no significant differences in the mass coefficients of the main organs between the medication and control groups. The high-dose group exhibited slight hepatic and pulmonary pathological changes and significantly reduced sperm counts in the epididymis, but no significant changes in serum sexual hormones (P < 0.05).

CONCLUSIONThree-month medication of Shen Yan Ling at 1.25 - 5.00 g/kg produced no significant accumulated toxicity on rats, but it had a negative effect on their reproductive function at a higher dose of > or = 5.00 g/kg.

OBJECTIVESTo investigate the effect of administration of MPA with/without TU on serum sexual hormones and spermatogenesis of male rats.

METHODSTwenty rats had been classified into four groups. Each group received injection of saline(group A) or MPA(37.5 or 75 mg/kg) (group B or group C, respectively) or MPA (75 mg/kg) + TU (25 mg/kg) (group D) every month during three months. Data from serum sexual hormones (FSH, LH, T), sperm counting and motility had been collected and analysed.

RESULTSSpermatogenesis of rats undergoing administration of MPA with or without TU had been suppressed. Serum FSH and LH of group B, C, D declined, and so did serum T of group D. Testis of rats of group D atrophied and sperm counting of group D decreased remarkably compared with group B and C. But there was no statistics difference of the sexual hormone level among group B, C and D.

CONCLUSIONSAdministration of MPA alone could suppress the levels of FSH and LH and block the spermatogenesis of male rats. MPA combined with TU could offer stronger suppression on spermatogenesis. Mechanism of the suppression on spermatogenesis of MPA + TU is not only limited in the feed-back of gonadotropin, but there maybe exist a direct suppression on testis.
