Objective To investigate the expression and prognostic significance of mediator complex subunit 8 (MED8) in gastric cancer and its impact on the cell cycle.Methods The expression of MED8 in gastric cancer and adjacent tissues and its correlation with patients' prognosis were analyzed using public databases.A validation cohort of 104 patients who underwent radical resection for gastric cancer in the First Affiliated Hospital of Bengbu Medical College from June 2012 to July 2017 was included.The receiver operating characteristic curve was established to evaluate the predictive value of MED8 for postoperative 5-year survival.Bioinformatics tools were used to predict the biological roles of MED8 in gastric cancer.The effect of the MED8 level on the G1/S phase transition of gastric cancer cells (MGC-803) was analyzed via lentivirus transduction and flow cytometry.Western blotting was carried out to assess the impact of MED8 expression on the protein levels of cyclin-dependent kinase 4(Cdk4) and G1/S-specific cyclin-D1(CyclinD1) in MGC-803 cells.Results The high expression of MED8 in the gastric cancer tissue was associated with poor prognosis (P<0.001) and had prognostic significance (area under curve=0.733,P<0.001).Gene enrichment analysis suggested that MED8 may participate in the cell cycle process.Flow cytometry results revealed that the upregulation of MED8 expression promoted the transition of MGC-803 cells from the G1 phase to the S phase (P<0.001),while the downregulation of MED8 had the opposite effect (P<0.001).Western blotting showed increases in the protein levels of Cdk4 and CyclinD1 in MGC-803 cells with upregulated MED8 expression (all P<0.001),and decreases in the cells with downregulated MED8 expression (all P<0.001).Conclusion MED8 is highly expressed in gastric cancer and may affect its progression and prognosis by regulating the G1/S phase transition of gastric cancer cells.

BACKGROUND:
Benvitimod cream, a novel synthetic small molecule, was effective in treating mild-to-moderate plaque psoriasis. We conducted a phase III clinical trial to assess the efficacy and safety of benvitimod cream in patients with mild-to-moderate plaque psoriasis.
METHODS:
We randomly assigned 686 patients (2:1:1) to receive 1% benvitimod cream, 0.005% calcipotriol ointment or placebo twice a day for 12 weeks. The primary efficacy end points were the percentage of patients with a 75% or greater reduction from baseline in the psoriasis area and severity index (PASI 75) score and with a score of 0 or 1 in static physician's global assessment (sPGA) at week 12.
RESULTS:
The results showed that 50.4% of patients in the benvitimod group achieved PASI 75, which was significantly higher than that in the calcipotriol (38.5%, P < 0.05) and placebo (13.9%, P < 0.05) groups. The proportion of patients achieving an sPGA score 0 or 1 was 66.3% in the benvitimod group and 63.9% in the calcipotriol group, which were both significantly higher than that in the placebo group (34%, P < 0.05). In the long-term follow-up study, 50.8% of patients experienced recurrence. After retreatment with 1% benvitimod, 73.3% of patients achieved an sPGA score of 0 or 1 again at week 52. Adverse events included application site irritation, follicular papules, and contact dermatitis. No systemic adverse reactions were reported.
CONCLUSION:
During this 12-week study, benvitimod cream was demonstrated with high effectiveness and safety in patients with mild-to-moderate plaque psoriasis.

The transition from spermatogonia to spermatocytes and the initiation of meiosis are key steps in spermatogenesis and are precisely regulated by a plethora of proteins. However, the underlying molecular mechanism remains largely unknown. Here, we report that Src homology domain tyrosine phosphatase 2 (Shp2; encoded by the protein tyrosine phosphatase, nonreceptor type 11 [Ptpn11] gene) is abundant in spermatogonia but markedly decreases in meiotic spermatocytes. Conditional knockout of Shp2 in spermatogonia in mice using stimulated by retinoic acid gene 8 (Stra8)-cre enhanced spermatogonial differentiation and disturbed the meiotic process. Depletion of Shp2 in spermatogonia caused many meiotic spermatocytes to die; moreover, the surviving spermatocytes reached the leptotene stage early at postnatal day 9 (PN9) and the pachytene stage at PN11-13. In preleptotene spermatocytes, Shp2 deletion disrupted the expression of meiotic genes, such as disrupted meiotic cDNA 1 (Dmc1), DNA repair recombinase rad51 (Rad51), and structural maintenance of chromosome 3 (Smc3), and these deficiencies interrupted spermatocyte meiosis. In GC-1 cells cultured in vitro, Shp2 knockdown suppressed the retinoic acid (RA)-induced phosphorylation of extracellular-regulated protein kinase (Erk) and protein kinase B (Akt/PKB) and the expression of target genes such as synaptonemal complex protein 3 (Sycp3) and Dmc1. Together, these data suggest that Shp2 plays a crucial role in spermatogenesis by governing the transition from spermatogonia to spermatocytes and by mediating meiotic progression through regulating gene transcription, thus providing a potential treatment target for male infertility.

OBJECTIVETo establish questionnaire scaling and reliability and examine the clinical and psychometric validity of the quality of life assessment based on Traditional Chinese Medicine for advanced gastric cancer (QLASTCM-Ga).
METHODSThe QLASTCM-Ga was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pretesting and quantitative statistical procedures. The questionnaire was administered to 240 patients diagnosed with advanced gastric cancer before and after treatment. Structured group methods were employed to establish a general and a specifific module respectively. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness.
RESULTSThe three identified scales of the QLASTCM-Ga and the total score demonstrated good psychometric properties. Test-retest reliability of the total scale and all domains ranged from 0.90 to 0.94, and internal consistency ranged from 0.86 to 0.93. Correlation and factor analysis demonstrated good construct validity. Signifificant difference in the subscales and the total score were found among groups differing in traditional Chinese medicine syndrome, supporting the clinical sensitivity of the QLASTCM-Ga. Statistically signifificant changes were found for each scale and the total score. Responsiveness was also good.
CONCLUSIONSThe QLASTCM-Ga demonstrates good psychometric and clinical validity to assess quality of life in patients with advanced gastric cancer undergoing traditional Chinese medicine therapy. This study is an important fifirst step for future research in this area.

OBJECTIVEIn this study, we aimed at exploring the association between work-related musculoskeletal disorders (WMSDs) and work organization based on a case-control study.
METHODSA total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe disease or musculoskeletal discomforts. We used a modified version of the questionnaire developed by the NMQ and the DMQ to investigate individual and work-related factors.
RESULTSA total of 13 variables (P<0.1) were selected by the chi-square test and finally, 7 variables entered into the equation, with 6 variables reaching statistical significance (P<0.05). The odds ratios (OR) of 'work changing with season' and 'sufficient rest time' did not reach 1 (0.749 and 0.441, respectively). In addition, 'sufficient rest time' seemed to be the stronger protective factor according to its higher standardized coefficient. And 'repetitive work every minute', 'constantly repetitive work' (every day), 'shortage of site personnel', and 'often switching shifts with others' seemed to be the risk factors.
CONCLUSIONWork organization may have comprehensive effects on the occurrence of WMSDs. This pattern of associations suggests that further investigation into the mechanism of how work organization affects the prevalence of WMSDs is required.

OBJECTIVETo investigate the therapeutic efficacy and safety of aspartate-ornithine granules in patients with nonalcoholic steatohepatitis (NASH).
METHODSSeventy-two patients with NASH were included in this multiple-dose parallel controlled clinical trial and received a 12-week course of aspartate-ornithine granule treatment at either high-dose (6 g bid po; n = 38) or low-dose (3 g bid po; n = 34). Clinical efficacy was assessed by monitoring data from urinalysis, serologic tests (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and triglyceride (TG)), and abdominal computed tomography (CT) scan. Safety was assessed by occurrence of adverse events (fatigue, anorexia, abdominal distension, nausea, and vomiting). Statistical analyses were conducted to determine the significance of differences between parameters before (baseline) and after treatment.
RESULTSAfter 12 weeks of treatment, the liver and spleen CT ratios in both the high-dose group (0.89 +/- 0.19) and the low-dose group (0.80 +/- 0.15) were significantly higher than at baseline (S = 329, P less than 0.0001 and S = 246, P less than 0.0001); the overall improvement was more robust in the high-dose group (52.63%) than in the low-dose group (38.23%) (Z = -2.1042, P less than 0.05). After 6 and 12 weeks of treatment, the serum ALT levels in both the high-dose group and the low-dose group were significantly lower than at baseline (6 weeks: S = 324.5, P less than 0.0001 and S = 223, P less than 0.0001; 12 weeks: S = 370.5, P less than 0.0001 and S = 297.5, P less than 0.0001); the overall improvement was more robust in the high-dose group (79.0%) than in the low-dose group (53.0%) (Z = -2.0533, P less than 0.05). Similar trends were seen for the serum levels of AST and GGT after 6 and 12 weeks of treatment (all P less than 0.01) and serum levels of TG after 12 weeks of treatment. The rate of adverse reactions was low and similar between the two groups (high-dose: 4.8% and low-dose: 4.4%; all gastrointestinal).
CONCLUSIONAspartate-ornithine granule therapy was an effective and safe treatment of nonalcoholic steatohepatitis, with the higher dose of 6 g bid po providing more robust clinical benefit without affecting the safety profile.

OBJECTIVETo evaluate clinical results of an interspinous stabilization system (Wallis) in treating lumbar degenerative disease in the short-term.
METHODSFrom August 2007 to June 2010,48 patients with lumbar degenerative disease who were treated with interspinous stabilization system, the data of patients were analyzed retrospectively. In all of the 48 cases, there were 30 males and 18 females with an average age of 54.2 years (ranged, 40 to 68 years). Forty-four cases were with single segment and 4 cases with two segments. Of them, 4 cases were in L3, 4, 40 cases were in L4, 5, 4 cases were in L3, 4 and L4, 5. The radiographic data of patients were analyzed. Clinical effects were evaluated by Japanese Orthopedic Association (JOA) score system and low back pain disability questionnaire (Oswestry) and Odom method.
RESULTSAll the patients were followed up from 1 to 2 years with an average of 18 months. According to Odom's criteria, 20 cases obtained excellent results, 24 good, 4 fair. JOA score increased from 12.4 +/- 2.7 preoperatively to 26.1 +/- 2.0 postoperatively (P < 0.01). Oswestry score decreased from 14.1 +/- 2.9 preoperatively to 5.5 +/- 1.8 postoperatively (P < 0.01). The posterior height of intervertebral space and height of nerve root canal increased compared with that of preperative height.
CONCLUSIONThe treatment of lumbar degenerative disease with interspinous stabilization system can obtain satisfactory effects in the near future. It can retain dynamic stable of corresponding segments, expand volume of vertebral canal, and is safe and feasible.
