OBJECTIVETo study the effects of soil microbes of habitats, endophytic fungi and root surface fungi of Huperzia serrata on rooting rate of the cuttings and on several physiological and biochemical indexes.

METHODThe cuttings of H. serrata were planted on soil I of primary habitat, the soil II had been inoculated endophytic fungi and root surface fungi, the soil III had been auto-claved, rooting rate was examined, and soluble protein and soluble sugar contents, activities of PPO and POD, flavonoids and huperzine A contents were determined.

RESULTCompared with the H. serrata that were planted on soil III, soil I and soil II were found to increase the rooting rate by 10% and 16%, soil II increased the soluble protein contents of stem of H. serrata (P < 0.05), Soil I increased the soluble sugar contents of leaves and stem of H. serrata (P < 0.05), soil I and Soil II increased the flavonoids contents of H. serrata (P < 0.05).

CONCLUSIONSoil microbes from primary habitat, endophytic fungi and root surface fungi promote rooting, they also increase plant metabolism level of H. serrata.

OBJECTIVETo study the effects of soil microbes of habitats on the cuttings rooting of Huperzia serrata and its mechanism.

METHODThe cuttings of H. serrata were planted on the primary habitat soil and on the soil autoclaved, rooting rates were examined respectively. Changes of contents of phenolic compounds (catechin, quercetin, chlorogenic acid, ferulic acid) and indoleacetic acid (IAA) , and changes of activities of polyphenoloxidase (PPO) and peroxydase (POD) during the cuttings rooting were determined.

RESULTSoil microbes of primary habitat could increase the rooting rate and the number of roots, could increase contents of catechin, chlorogenic acid, ferulic acid and IAA during rooting, and could affect activities of PPO and POD.

CONCLUSIONDuring the rooting higher contents of catechin, chlorogenic, ferulic acid and IAA caused by soil microbes of primary habitat are important factor for rooting rate.

OBJECTIVETo discuss the treatment and prevention of the complications resulted from intraoral mandibular angle reduction.

METHODSFrom July 2002 to August 2008, 672 cases underwent intraoral mandibular angle reduction. The 59 cases with postoperative complications were treated and followed up.

RESULTSNo severe complication happened. In 18 cases with asymmetry, 13 cases improved through soft tissue adjustment, 5 cases were reoperated with good results. Intraoperative precise osteotomy was needed to prevent asymmetry. 3 cases with infection healed with drainage and anti-inflammatory treatment. Intraoperative aseptic manipulation and adequate drainage were necessary to prevent infection. 20 cases with labial numbness recovered 3 - 6 weeks later. 5 cases with temporary facial nerve injury recovered 2 - 3 months later. 12 cases with bleeding and hematoma were treated by dressing with pressure and drainage and healed 3 weeks later. Skin necrosis resulted from tight dressing occurred in one case, which were treated with skin graft. Intraoperative protection of nerve and vessels, as well as the dressing were very important.

CONCLUSIONSMost of the complications can be treated and recovered well. Preoperative design, precise manipulation and postoperative reliable dressing are the key points to prevent complications.

OBJECTIVETo evaluate the effect and safety of L-carnitine in the treatment of idiopathic oligoasthenozoospermia based on current clinical evidence.

METHODSWe searched the Cochrane Library, PubMed, MEDLINE, EMBASE, CNKI, VIP, CBM and Wanfang Database from the establishment to April 2014 for the published literature on the treatment of idiopathic oligoasthenozoospermia with L-carnitine. We conducted literature screening, data extraction, and assessment of the methodological quality of the included trials according to the inclusion and exclusion criteria, followed by statistical analysis with the RevMan 5. 2 software.

RESULTSSeven randomized controlled trials involving 751 patients with idiopathic oligoasthenozoospermia met the inclusion criteria, and 678 of them were included in the meta-analysis. L-carnitine treatment achieved a significantly increased rate of spontaneous pregnancy as compared with the control group (RR = 3.2, 95% CI 1.74 to 5.87, P = 0.0002). After 12-16 and 24-26 weeks of medication, total sperm motility (WMD = 5.21, 95% CI 2.78 to 7.64, P < 0.0001 and WMD = 9.29, 95% CI 1.28 to 17.29, P = 0.02) and the percentage of progressively motile sperm (WMD = 12.44, 95% CI 4.58 to 20.31, P = 0.002 and WMD = 9.76, 95% CI 3.56 to 15.97, P = 0.002) were remarkably higher than those in the control group, but no statistically significant differences were observed in sperm concentration between the two groups (WMD = 4.91, 95% CI -2.63 to 12.45, P = 0.2 and WMD = 0.93, 95% CI -3.48 to 5.34, P = 0.68). After 12-16 weeks of treatment, the percentage of morphologically abnormal sperm was markedly decreased in the L-carnitine group as compared with the control (WMD = -2.48, 95% CI -4.35 to -0.61, P = 0.009), but showed no significant difference from the latter group after 24-26 weeks (WMD = -4.38, 95% CI -9.66 to 0.89, P = 0.1). No statistically significant difference was found in the semen volume between the two groups after 12-16 or 24-26 weeks of medication (WMD = -0.13, 95% CI -0.43 to 0.18, P = 0.42 and WMD = 0.28, 95% CI -0.02 to 0.58, P = 0.07). No serious L-carnitine-related adverse events were reported in 4 of the randomniized controlled trials.

CONCLUSIONThe current evidence indicates that L-carnitine can improve spontaneous pregnancy and semen parameters in the treatment of idiopathic oligoasthenozoospermia, with no serious adverse reactions.

OBJECTIVESTo investigate prognostic effect of postoperative resection-margin status for intraoperatively positive resection margin in advanced gastric cancer and discuss the treatment choice for intraoperatively positive resection margins.

METHODSA retrospective study was investigated in 64 advanced gastric cancer patients with positive resection margin after potentially curative resection. The survival between 50 patients who was re-excised to a negative resection margin (NR group) and 14 patients who were left with positive resection margin (PR group) was compared. Prognostic factors were analyzed using univariate and multivariate Cox regression model analysis.

RESULTSThe median survival in the PR group was 17.0 months (95%CI: 11.6 - 22.4) as compared with 23.0 months (95%CI: 20.5 - 25.5) in the NR group (P = 0.045). However, resection-margin status lost significance on multivariate analysis. In the subgroup of D2 lymphadenectomy, the median survival in the PR group and NR group were 17.0 months (95%CI: 12.0 - 22.0) and 24.0 months (95%CI: 19.8 - 28.1) respectively; multivariate analysis further identified resection margin status as an independent prognostic factor.

CONCLUSIONSRe-excision for intraoperatively positive margin to negative margin improves the prognosis of the patients with advanced gastric cancer, and re-excision is the first choice when intraoperative frozen section detects a positive margin. Routine frozen section of resection margin should be mandatory in all advanced gastric cancer undergoing potentially curative surgery.

AIM:To find new biomarkers in the sera of retinoblastoma (Rb) patients with surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI TOF MS) and protein chip technique.METHODS:SELDI TOF MS, IMAC30 and CM10 protein chips were used to analyze the protein profiles from sera of 18 patients with Rb and 17 age matched controls. The protein profiling was analyzed statistically by Ciphergen protein chip software 3.0.2. The test was applied to compare the protein peak intensity. Fisher's exact test was used to compare the predominance of differential protein peaks appeared in patients.RESULTS:With IMAC30 protein chips, there were 26 proteins which appeared different in sera of patients with Rb compared to normal children. Among them, 21 proteins, I.e. 7746, 7014, 11713, 3049, 7084, 7299, 5888, 2544, 12575, 5489, 9658, 9575, 9929, 10161, 8955, 1886, 10617, 6209, 2411, 7374, 6614m/z were up regulated and 5 proteins, I.e. 8382, 7923, 7972, 8590, 66576m/z, were down regulated(P<0.01). Using the 7014 protein peak for statistical analysis, we could differentiate the patients with Rb from the healthy children with a sensitivity of 94.4% and a specificity of 82.4%. By CM10 protein chips, 4 proteins, including 3 up regulated proteins(5888, 6097, 7798 and 1 down regulated protein (8590m/z), were detected in Rb patients (P<0.01). The sensitivity and specificity were 83.3% and 70.6% respectively when 7798m/z protein peak was selected for statistical analysis.CONCLUSION:There are a few candidates as Rb biomarkers in the sera of Rb patients. SELDI TOF MS protein chip technology could be a potential method in the clinical screening test of Rb.

Objective To study the expressions of nucleostemin gene mRNA and Ki-67antigen in pituitary adenomas and investigate the role of nucleostemin gene in the tumorigenesis and development of pituitary adenomas. Methods Seventy-one samples of pituitary adenomas were collected. Semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of nucleostemin gene mRNA in samples. Immunohistochemistry technique was applied to examine Ki-67 antigen expression in the paraffin sections of samples. At the same time,coherent clinical data were collected. Results Nucleostemin gene mRNA was detectable in all samples of pituitary adenomas. Between invasive and noninvasive pituitary adenomas, the difference of nucleostemin expression was extremely significant (P＜0.01), and Ki-67 labeling index (LI) was also significantly different (P＜0.05). The difference of Ki-67LI between recurrent and non-recurrent groups was significant (P＜0.05). There was a positive correlation between nucleostemin gene and Ki-67LIlevels (r=0.237, P＜0.05). Conclusions Nucleostemin gene plays an important roles in the invasion of human pituitary adenoma. Expression of nucleostemin gene is positively related to Ki-67 antigen expression, and both may be the valid clinical detection markers for assessing proliferation, invasion and recurrence of pituitary adenomas.
