Using universal primer Tyl-copia retrotransposon RT, the conserved reverse transcriptase domain of about 260 bp was amplified by RT-PCR from the Dendrobium officinale which induced by 100 micromol x L(-1) abscisic acid (ABA), indicating these retrotransposons activated by 100 micromol x L(-1) ABA. The amplicons were recovered and cloned,then sequenced and analyzed by related bioinformatics software. Forty-two Ty1-copia like retrotransposon RT transcriptionally activated were obtained with high heterogeneity. The length of these sequences varied from 247 to 266 bp, and was rich in AT and homology ranged from 46.3% to 98.9%. The same to Ty1-copia like retrotransposon RT of genome, different c/s-acting regulatory elements induced by stress conditions and the starting transcription signals, corresponding to CAAT box, TATA box conserved sequences and some other regulatory elements. The c/s-acting regulatory elements induced by stress conditions of reverse transcriptase transcriptionally activated of Tyl-copia retrotransposons were significantly increased than that of Ty1-copia like retrotransposon RT of genome. When being translated into amino acids, fifteen sequences presented stop codon mutation, nineteen sequences presented frameshift mutation, and all sequences presented conserved sequence "SLYGKQ" mutation. Five categories were identified through phylogenic analysis after alignment analyses of their amino acid sequences, and with Ty1-copia like retrotransposon RT of genome having low homology, which indicated that reverse transcriptase transcriptionally activated of Ty1-copia retrotransposons which induced by ABA had Significantly differences with Ty1-copia like retrotransposon RT of genome.

Taking Doctor HUANG Shi-ping as the representative, the school of Huang's golden needle is based on Chinese martial art. Golden needles are adopted as main tool. Attaching great importance on the combination of acupuncture and moxibustioin, it is also characterized with penetrating needling with long needles. Through the development of three generations, it once outshone other schools in the field of acupuncture, and became famous all over the world. It made great contribution to the development of the course of acupuncture. However, with the development of the history, the form of acupuncture education as well as apparatus were all undergone an unified reform. Therefore, Doctor HUANG Shi-ping's acupuncture school be lost gradually.

To establish single- and double-transfected transgenic cells stably expressing hMATE1, hMATE1 cDNA was cloned by RT-PCR from human cryopreserved kidney tissue, and subcloned into pcDNA3.1(+) plasmid by virtue of both HindIII and Kpn I restriction enzyme sites. Subsequently, the recombined pcDNA3.1(+)- hMATE1 plasmid was transfected into MDCK, MDCK-hOCT1 or MDCK-hOCT2 cells using Lipofectamine 2000 Reagent. After a 14-day-cultivation with hygromycin B at the concentration of 400 µg · mL(-1), all clones were screened with DAPI and MPP+ as substrates to identify the best candidate. The mRNA content of hMATE1, the cellular accumulation of metformin with or without cimetidine as inhibitor, or transportation of cimetidine was further valuated. The results showed that all of the three cell models over expressed hMATE1 mRNA. The cellular accumulation of metformin in MDCK-hMATE1 was 17.6 folds of the control cell, which was significantly inhibited by 100 µmol · L(-1) cimetidine. The transcellular transport parameter net efflux ratios of cimetidine across MDCK-hOCT1/hMATE1 and MDCK-hOCT2/hMATE1 monolayer were 17.5 and 3.65, respectively. In conclusion, cell models with good hMATE1 function have been established successfully, which can be applied to study the drug transport or drug-drug interaction involving hMATE1 alone or together with hOCT1/2 in vitro.

OBJECTIVE:
To determine the relationship between bone alkaline phosphatase (BAP) and cross-linked N-telopeptides of type I collegen(NTX) and bone mineral density in healthy men aged 20-80.
METHODS:
BAP and NTX of 389 healthy men were measured by ELISA. BMD at the lumbar spine and the hip as measured by dual energy X-ray absorptiometry. The correlation of bone biochemical markers with age and BMD fit 10 regression models.
RESULTS:
BAP and NTX negatively correlated with age. The cubic regression model was better with age-related changes of bone biochemical markers as compared with the other regression models and the coefficients of determination of fitting curve were 0.013-0.029 (P< 0.05). The value of bone biochemical markers as the highest during 20-29 age groups, then they decreased to a nadir level in the 50-59 years age. After 60 years, bone formation markers remained stable; however resorption marker increased slightly. After adjustment for age, weight, height, BMI, and smoking, bone biochemical markers were negatively correlated with most sites of BMD.
CONCLUSION
BAP and NTX may be relatively sensitive and specific markers to evaluate age-related changes of bone turnover. It may benefit the prevention of osteoporosis by monitoring the level of BAP and NTX.

OBJECTIVETo explore the feasibility and safety of transvaginal external fascia trachelectomy to conservatively treat patients with stage Ia1 squamous carcinoma of the uterine cervix (SCC) and cervical intraepithelial neoplasia (CIN) III, who are not suitable to take cold knife conization (CKC).
METHODSFrom July 2002 to September 2010, those patients who had a strong desire to preserve the uterus or fertility but also are confronted with following situations received transvaginal external fascia trachelectomy: CIN III with large area lesion (colposcopically observed lesion area was larger than 3/4 of the cervix), or patients with CIN II-III suffered recurrence or had persistent lesion or positive margin after CKC or LEEP, or patients with CIN II-III upgraded into stage Ia1 SCC through LEEP and pathological confirmation (except for those with lymphovascular space invasion), or CIN III patients complicated with upper vaginal intraepithelial neoplasia (VAIN). Their clinical information and data were reviewed and analyzed.
RESULTSAmong the 79 cases, who underwent transvaginal external fascia trachelectomy, six were stage Ia1 SCC, 61 were CIN III with a large area lesion (23 cases had glandular involvement), three were CIN III complicated with VAIN, six were CIN III with persistent lesion after LEEP, two were CIN III with positive margins after LEEP, and one case had recurrence after conization. The median age of these patients was 33 years old, ranging from 23 to 40 years old. The mean operation time was 39 min (rang 20-60 min), the average amount of bleeding was 40 ml (rang 1-300 ml) and the mean hospital stay was 10 d ( rang 6-17 d). The CIN III patients complicated with VAIN received this surgery with resection of the adjacent vaginal mucosa more than 2 cm in 3.8% (3/79). The median follow-up time was 49 months (8-85 months) and none of these patients had ureteral injury or large amount of intraoperative or postoperative bleeding or post-operative recurrence. No patient complained any effect on their sexual life. Among the five patients with reproductive desire, one was at her 22 w gestation after one induced abortion and one spontaneous abortion, four patients experienced term birth in which three were cesarean section and one was natural labour.
CONCLUSIONSTransvaginal external fascia trachelectomy is a safe and effective conservative treatment for stage Ia1 SCC, CIN III with large area lesion, CIN III complicated with VAIN and CIN II-III suffering recurrence, persistent lesion or positive margins after CKC and others that are not suitable to take CKC.

To investigate the difference in absorptive of tetrahydropalmatine (THP) and l-tetrahydropalmatine (l-THP) in rat intestine as well as the mechanism of the absorption of THP, in situ single pass perfusion model was used and the concentration of THP in perfusate was determined by HPLC. The absorption rate constant (k(a)) and effective permeability values (P(eff)) of THP had no significant difference (P > 0.05) at concentration of 8, 16 and 32 microg x mL(-1) in perfusion or in four different regions of intestine of rat (duodenum, jejunum, ileum, colon). The absorption of l-THP and THP in jejunum had significant difference (P < 0.05). The k(a) and P(eff) of THP increased obviously when verapamil was co-perfused with THP, while those of l-THP were not influenced by verapamil. The absorption of THP in intestine showed the passive diffusion process, and without a special absorption region. The stereoselective absorption difference may result from stereoselective combination of P-glycoprotein with d-THP.

OBJECTIVETo evaluate the role of nutritional status on serum immunoglobulins, body weight and postoperative infectious-related complications in patients with Crohn's disease receiving perioperative parenteral nutrition (PN).
METHODS32 patients with Crohn's disease receiving perioperative parenteral nutrition in our department between 1984 and 1994 were enrolled in this survey. 16 patients with loss of body weight in the range of 15%-30% were assigned to the malnutrition group, the other 16 patients with normal weight or loss of body weight less than 15% to the control group. Serum IgM, IgG and IgA levels were measured before and after PN by enzyme-linked immunosorbent assays. Liver function, body weight changes and postoperative complications were also analyzed.
RESULTSIgM levels were elevated before PN in both groups [control group: (133 +/- 16) mg/dl, malnutrition group: (139 +/- 41) mg/dl; normal value: (110 +/- 35) mg/dl; P = 0.04], decreased to normal value [(105 +/- 29) mg/dl, P = 0.02] in the malnutrition group while having no obvious changes in the control group [(129 +/- 13) mg/dl, P = 0.34]. No significant changes in concentrations of IgG and IgA were found (P in the range of 0.20-0.57). The average weight gain was 1.862 kg in malnutrition group [before PN: (45.8 +/- 8.9) kg, after PN: (48.0 +/- 8.8) kg; P = 0.005] and no significant changes in the control group [before PN: (55.6 +/- 6.1) kg, after PN: (56.3 +/- 6.0) kg; P = 0.46]. There was an increase in infectious complications in the control group (control group: 4 cases, 25%, malnourished group: 2 cases, 12.5%; P = 0.13).
CONCLUSIONSPerioperative parenteral nutrition ameliorated the humoral immunity, increased the body weight in patients with obvious malnutrition, whereas it had little value for those without or with mild malnutrition.

OBJECTIVETo compare efficacy of different adjuvant chemotherapy regimens for stage II-III gastric cancer after D2 gastrectomy in Asian patients.
METHODSAssociated literatures were searched through electronic databases and hand-searching. Prospective randomized clinical trials (RCTs) comparing adjuvant chemotherapy after D2 gastrectomy with surgery alone were included in the study. Overall survival and disease-free survival were chosen as the endpoints. Relative hazard was analyzed by Bucher adjusted indirect comparison.
RESULTSTwo RCTs were selected, including comparison between S-1 versus surgery alone and comparison between XELOX versus surgery alone. There was no statistical difference in overall survival between the two regimens (HR=0.94, 95%CI:0.62-1.44, P=0.79). The recurrence risk of S-1 was slightly higher as compared to XELOX, but no statistical difference was found (HR=1.11, 95%CI:0.80-1.53, P=0.54).
CONCLUSIONThe adjuvant chemotherapy with S-1 is similar to XELOX for stage II-III gastric cancer after D2 gastrectomy in Asian patients.

OBJECTIVETo observe the efficacy and safety of Jingui Shengqi Pill in treating partial androgen deficiency in aging males (PADAM), and to explore the new approach in improving the quality of life in PADAM patients.
METHODSForty patients with PADAM were treated with JSP, the efficacy was evaluated with international index of erectile function (IIEF) scoring, PADAM questionnaire scoring, hormone, prostatic specific antigen (PSA), etc., and the data before treatment were compared with those after treatment in the same group.
RESULTSAfter 3 months of treatment, PADAM scoring and IIEF scoring were all significantly improved. Symptoms regarding physical ability, vasomotion, and psychical and mental condition all got improved more markedly than symptoms regarding sexual hypofunction. The serum level of testosterone was 3.85 +/- 0.36 before treatment and 5.02 +/- 0.83 after treatment (P < 0.05); luteinizing hormone of 7.33 +/- 2.14 and 4.84 +/- 1.43 (P < 0.01), follicle-stimulating hormone of 10.22 +/- 4.48 and 6.47 +/- 3.28 (P < 0.01), respectively. The level of PSA failed to change significantly (1.94 +/- 0.55 and 2.06 +/- 0.47, P > 0.05).
CONCLUSIONJSP is effective and safe in treating PADAM, the mechanism of it is different from supplementing extrinsic androgen. It may have produced the effect by means of favorably regulating the condition of sex hormone to improve the balance of pituitary-sex gland axis, so it has more extensive clinical application.
