BACKGROUND: Physical exercise can significantly reduce bone mass loss, relieve pain and improve bone metabolism in osteoporosis patients, but there is no evidence-based evidence. OBJECTIVE: To investigate the effect of different physical exercises on the treatment of primary osteoporosis. METHODS: Randomized controlled clinical trials regarding the therapeutic effect of physical exercise on primary osteoporosis were screened. The physical exercise group was subjected to physical exercise, and the control group had no regular exercise during the test. The main outcome measures included bone mineral density of lumbar spine L2-L4, visual analog scale score, bone metabolism index (osteocalcin, total type 1 procollagen amino terminal peptide, urine pyridinium/creatinine, blood calcium, blood phosphorus). The included outcome indicators were meta-analyzed using the Review Manager 5.3 software. RESULTS AND CONCLUSION: A total of 25 randomized controlled trials were included. Meta-analysis results showed that physical exercise could effectively improve the bone mineral density of L2-L4 segments in primary osteoporosis patients (mean difference=0.06, 95% confidence interval [0.04-0.08], P < 0.000 01, I2=89%). Subgroup analysis results revealed significant differences in the control group and five-animal exercise & Yi-Jin-Jing group, setting-up exercise group, composite exercise group, and incremental exercise group compared with control group (P < 0.05), while there was no significant difference between other exercise groups and control group (P > 0.05). Physical exercise significantly reduced the pain as determined by the visual analog scale in osteoporosis patients (mean difference=-0.93, 95% confidence interval [-1.08 to -0.79], P < 0.000 01, I2=83%). Exercise intervention could improve serum osteocalcin, total type 1 procollagen amino terminal peptide and blood phosphorus levels, and reduce urine pyridinium/creatinine and serum calcium levels. However, there was no significant difference between exercise groups and control group (P > 0.05). The results of Egger’s and Begg’s tests indicated that publication bias of the included studies was at a low level. All these findings indicate that physical exercise has significant interventional effects on bone mineral density and pain in patients with primary osteoporosis.

Based on the physiological properties of ammonium-resistant N2-fixingbacterium ( Klebsiella oxytoca NG13/pMC73A), the fermentation technology of it was studied. The basic medium of high-density culture was established, with glucose as carbon source coupled with appropriate nitrogen source and inorganic salts. At the middle and late phase of culture, glucose and ammonia were added to supply carbon source and nitrogen source, stabilizing the pHat 6.5 ~ 6.8. Optimal level of dissolved oxygen was kept by controlling aeration and stirring rate. Bacterium number of Klebsiella oxytoca NG13/pMC73A reached 600 ~ 700 x 10s cfu/mL at the end of culture. Compared with previous technology, bacterium number was increased by more than ten-fold with a comparable culture period.

To further explore the result of bilingual teaching in pediatrics,we randomly chose 200 undergraduates of 4 class and released students'questionnaires about bilingual teaching with teaching content before and after class to assess students'understanding of bilingual teaching and analysed appraisal result.We found no significant difference of student score between students accepting bilingual teaching and not accepting the bilingual teaching,but there was difference for English tests and expression level.So we think that students can fully accept the bilingual teaching of pediatrics under the premise with selecting appropriate teaching methods and means.

Objective To investigate the effect of KIR-HLA receptor-ligand model on the unrelated allo-hematopoietic stem cell transplantation (Allo-HSCT) of acute lymphoblastic leukemia (ALL). Methods The KIR genotype of 23 pairs of ALL patients and their HLA-matched unrelated donors obtained from the Database of China Marrow Donor Program. KIR genotype was determined using PCR-SSP. The expression of inhibitory KIR(iKIR) was determined by flow cytometry analysis on recipients after HSCT. Results Among all 23 donor/recipient pairs, 17 donors with KIR2DL2/L3 could find corresponding HLA-Cw1, 3, 7, 8, 12, 14 ligands in their recipients. Six donors with KIR2DL1 could match with HLA-Cw6, 15 in recipients. Sixteen donors with KIR3DL1 could recognize HLA-Bw4 and 12 donors with 3DL2 could find HLA-AI1 in their corresponding recipients, respectively. Ninteen patients were successfully transplanted, and the death rate of transplantation were 33.3% (2/6)and 40.0% (2/5) in KIR receptor-ligand matched model and the graft versus leukemia(HVG) KIR ligand-mismatching pattern. The frequency of acute graft versus host disease(GVHD) was 50.0% and death rate was 12.5% (1/8) in GVH KIR ligand-mismatching. The incidence rate of activated GVHD(aGVHD) was 20.0% in the HVG KIR ligand-mismatching. Five donor/recipient pairs of KIR gene typing were the KIR-haplotype A, 2 donor/recipient pairs with KIR2DS4 * 001/002 were died, 3 donor/recipient pairs with KIR2DS4 * 003-007 were obtained the disease free survival. The expression of CD158a/2DL1 was low when the patient had no aGVHD, but became much higher when aGVHD occurred. The percentage of NK cell of the patients was decreasing since transplantation, but still higher than normal after HSCT[ (23.4 ± 3.8 ) % vs (2.04 ± 0.58) %, P < 0.05 ]. Conclusion Analysis on KIR-HLA gene loci pattern may provide a useful parameter in predicting the clinical outcome of HLA-matched unrelated allogeneic hematopoietic stem cell transplantation for leukemia patients. Moreover, it may help to increase overall survival and disease free survival after HSCT by preventing the development of GVHD.

Objective To study the influence of human leucocyte antigen(HLA) and major his-tocompatibility complex class Ⅰ chain-related gene A (MICA) specific antibodies on renal allograft function and graft rejective reaction by monitoring their changes from preoperative to postoperative pe-riods. Methods Twenty-seven patients with renal aliografts were tested with the specificity of anti-HLA antibodies (anti-HLA class Ⅰ and anti-HLA class Ⅱ) and anti-MICA antibodies and their posi-tive value changes by flow PRATM beads. The HLA genotype was integrated to distinguish donor specific antibody(DSA) and non-donor specific antibody(NDSA). Their serum creatinine levels and clinical data were analyzed simultaneously. Results Of the 27 patients, 22 cases accepted renal transplantation from dead bodies and 5 eases accepted from live donors. Except 1 failed patient, the other 26 patients had good functional renal allografts. Twenty-four survival patients were followed up on month 1, 3, 6 and 12 after transplantation. Seven out of 27 patients had pre-exist antibody before transplantation. Among them, 2 patients had anti-HLA antibody; 3 patients had anti-MICA antibody; 2 patients had both anti-HLA and anti-MICA antibody. Three patients with no anti-HLA and anti-MICA antibodies before transplantation created antibodies after transplantation from 3 to 6 months. One patient created NDSA after transplantation and appeared chronic rejection. There were 3 patients who had anti-MICA antibodies before transplantation. The expression levels of antibodies had changed from high to low, but the specific anti-MICA antibody had not changed during the follow-up on month 1, 3, 6 and 12 after transplantation. The patient with pre-transplantation low level of anti-HLA class Ⅱ antibody appeared acute rejection with fever and his CMV was positive as well. The patient's SCr levels changed from 171 μmol/L to 236 μmol/L after I to 3 months post-transplantation. Twenty-four patients were divided into positive and negative groups according to the specific antibody. There was significant difference of SCr levels between the 2 groups 1 month and 1 year after transplantation(P= 0.03, 0.05). Conclusions It is important to detect the specificity and positive value of anti-HLA antibodies and anti-MICA antibody regularly during the post transplantation follow-up. This will make an effective therapy for decreasing the occurrenee and development of acute or chronic rejection and hy-pofunction on renal allograft.

To investigate the absorption kinetics of Cu B-SDC/PLC-MMs in rat different intestinal segments and compared with the absorption of Cu B suspension. The in vitro everted gut sacs model was established to study the absorption characteristics of Cu B-SDC/ PLC-MMs in rat duodenum, jejunum, ileum and colon, and the content of cucurbitacin B was detected by HPLC method, and the effects of concentrations on intestinal absorption were evaluated as well. The results showed that the absorption of Cu B-SDC/PLC-MMs was linearity at different intestine segment and different concentrations (R2 > 0.9), which was consistent with zero order rate process. The Ka of different intestine segments showed a concentration-dependent increasing along with the raised concentration of Cu B-SDC/ PLC-MMs, indicating that it was likely to be a mechanism of passive absorption. The best absorption site of Cu B-SDC/PLC-MMs was ileum, and its absorptions in different intestinal segments were superior to cucurbitacin B suspension. SDC/PLC-MMs could significantly enhance the intestinal absorption of cucurbitacin B, and the study of intestinal absorption kinetics of Cu B-SDC/PLC-MMs had gave a support to its further reasonable solidfication.

Objective To investigate the prediction of anti-human leukocyte antigen antibodies (HLA) and anti-major histocompatibility complex class I-related chain A antibodies (MICA) to the development of acute rejection (AR) and kidney allograft function. Methods Forty-one kidney transplant patients were prospectively tested for anti-HLA and anti-MICA. Thirty-seven patients were screened using Luminex/single-antigen beads to determine the HLA and MICA-specific antibody levels at 0,30,90, 180,360,720 and 1080 days post-transplantation. The patients and donors of HLA and MICA allele typing were determined by PCR-SSOP, and donor specific antibody (DSA) and non-donor specific antibody (NDSA) were identified.Simultaneously,their serum creatinine (SCr) levels and clinical data were analyzed. Results Nine patients (21.95 % ,9/41 ) had pre-existing anti-HLA and(or) anti-MICA, including 6 cases of anti-MICA,2 cases of anti-HLA, and one case of anti-MICA and anti-HLA. Nine patients had pre-existing DSA and NDSA. In the 37 patients, 6 patients (16.2% ) developed de novo anti-HLA, and 3 (8.1%) developed de novo antiMICA. In patients positive for de novo anti-HLA, the titer of antibody was gradually increased during the follow-up of three years. Four patients out of 9 patients with pre-existing antibodies were suffered from AR (44.4%); In 6 patients positive for de novo anti-HLA,three cases (50.0%) were suffered from AR; In three patients positive for de novo anti-MICA,no AR occurred (P＜0.05). In two patients positive for DSA of HLAⅡ antibody detected at the third and seventh day after transplantation, the renal grafts were renovecd due to rejection. The Scr levels in patients positive for pre-existing MICA with AR were higher than in those positive for pre-existing MICA without AR at each scheduled time point during the follow-up period (P＜0.05). The Scr levels in patients negative for antibodies pre-transplantation and having AR were higher than in those having no AR at each scheduled time point during the follow-up period (P＜0. 01 ). The Scr levels in patients positive for de novo HLA and MICA and having AR one month following transplantation were higher than in those negative for antibodies and having no AR (P＜0.01 ). Conclusion Pre-existing and de novo anti-HLA were the irnportant factors for the development of AR, but the mismatch of HLA and MICA alleles in donors and patients was primary causes for generation of de novo antibodies.

OBJECTIVETo investigate the clinical value of pleural effusion lung ProGRP, neuron specific enolase (NSE), cytokeratin fragment 19 (CYFRA21-1), carcino-embryonic antigen (CEA), carbohydrate antigen 153 (CA153), carbohydrate antigen 19 - 9 (CA19-9) in differential diagnosis and histological typing of malignant pleural effusion caused by lung cancer.

METHODSAll the 171 patients with malignant hydrothorax caused by lung cancer were from coal-mine area of Kailuan. They were divided into the small cell lung cancer (SCLC) group (n = 39), the adenocarcinoma group (n = 99) and the squamous cell carcinoma group (n = 37). The patients with benign pleural effusion served as the controls (n = 30). The diagnostic value of pleural effusion ProGRP, NSE, CYFRA21-1, CEA, CA153 and CA19-9 was compared for each group.

RESULTSYouden index and the accurate rate of pleural effusion ProGRP + NSE (sequence test) were the highest in the diagnosis of malignant hydrothorax caused by SCLC. CEA + CA153 + CA19-9 (sequence test) was the highest in the diagnosis of malignant hydrothorax caused by adenocarcinoma. CYFRA21-1 + CEA + CA153 (on parallel test) were the highest in the diagnosis of malignant hydrothorax caused by squamous cell carcinoma. The Yonden index and the accurate rate were the highest by the single detection of CYFRA21 (0.5514 and 0.6878), and by the combined detection of ProGRP + CYFRA21-1 + CEA (on parallel test) (0.7029 and 0.8878).

CONCLUSIONThe first pleural effusion tumor markers of malignant hydrothorax caused by the SCLC, adenocarcinoma of lung, and lung squamous cell carcinoma are ProGRP, CEA and CYFRA21-1, respectively. The best combinations of pleural effusion tumor marker in diagnosis of malignant hydrothorax caused by the SCLC, adenocarcinoma of lung, lung squamous cell carcinoma and lung cancer are the combined detection of ProGRP + NSE (sequence test), combined detection of CEA + CA153 + CA19-9 (sequence test), the combined detection of CYFRA21-1 + CEA + CA153 (on parallel test) and ProGRP + CYFRA21-1 + CEA (on parallel test), respectively.

OBJECTIVETo establish a real-time quantitative reverse transcriptase polymerase chain reaction (RQ-RT-PCR) for quantitative detection of the common molecular markers that have affirmative clinical significance in the acute and chronic leukemia patients, and evaluate its significance in diagnosing leukemias and monitoring minimal residual disease (MRD).

METHODSPrimers and TaqMan probes were designed for detecting various fusion transcripts and normal abl gene was used as the internal control. The expression level of fusion transcripts in 202 newly diagnosed leukemias were determined.

RESULTSIn absolute quantity, expression level of the fusion transcripts in various leukemias was b3a2 (b2a2) 47614.63, e1a2 98847.53, AML1-ETO 300029.51, PML-RAR alpha 25506.28, respectively, while in relative quantity to abl, the levels were 1.05, 0.91, 5.33 and 0.55, respectively.

CONCLUSIONThe relative quantification of gene expression level by using RQ-RT-PCR to abl control gene is more accurate and direct viewing. Different levels of transcription of corresponding fusion genes are found in various subtypes of leukemias at diagnosis, among which the level of AML1-ETO was higher and PML-RAR alpha lower.
