Objective To analyze the impact of rs3826392 polymorphism in MKK4 promoter on prognosis of colorectal cancer cases (CRC) receiving adjuvant chemotherapy. Methods The associations between rs3826392 genotype of 203 CRC cases receiving adjuvant chemotherapy and clinicopathologic factors,overall survival (OS), disease free survival (DFS) were analyzed retrospectively. Results No association was found between rs3826392 genotype and clinicopathologic factors (P > 0.05). TG+GG genotype had better OS (P = 0.018) and DFS (P =0.019) when compared with TT genotype. Cox multivariate model showed rs3826392 TG+GG genotype remained independent favorable factor for OS(HR = 0.389;95%CI = 0.177-0.855) and DFS(HR=0.491;95%CI = 0.271-0.890) respectively. Conclusion -1304G variant genotypes (i.e., TG+GG) in rs3826392 may be the biomarker of better prognosis in CRC receiving adjuvant chemotherapy.

Objective To observe Rongxin Pills in the treatment of viral myocarditis in children (deficiency of both qi and yin and heart meridian stasis syndrome) and the effectiveness and clinical application of safety.Methods Viral myocarditis patients (280 cases,deficiency of both qi and yin and heart meridian stasis syndrome),according to 3:1 ratio as the test group (n =21 0) and control group (n =70).The test group took orally Rongxin pills each time 4.5～9 g,3 times daily;the control group oral coenzyme Q10 capsule each time 10 ～ 20 mg,twice daily.The course of treatment was 28 d.The experiment was carried out with the random and double blind method.The symptoms of myocarditis,integrated and electrocardiogram,echocardiography,myocardial enzymes,as well as the efficacy of traditional Chinese medicine and improvement of the effect of the disease were observed.Results The results of FAS (PPS) analysis showed that 28 d after treatment,the symptom score and mean of experimental group and control group were 5.975 (6.000) and 4.721 (4.788).The syndromes of the total effective rates were 91.62％ (90.59％) and 70.59％ (71.21％),curative effect the total effective rates were 90.14％ (92.08％) and 72.06％ (72.73％).The total effective rate of experimental group was higher than that of the control group,the difference was statistically significant.In this experiment,three cases of clinical adverse events were reported,which were not related to the experimental drug.It also not belongs to adverse drug reactions.Conclusion Rongxin Pill in the treatment of viral myocarditis in children (deficiency of both qi and yin and heart meridian stasis syndrome) is more effective than coenzyme Q 10 capsule,and there was no indication of higher risk of clinical application.

OBJECTIVETo explore the direct contribution of dexamethasone (Dex) for insulin resistance inducing in thecal cells and effects of berberine (Ber) and puerarin (Pue).

METHODSOvarian thecal cells from porcine follicles were isolated and cultured in vitro. Insulin resistance of thecal cells was induced by Dex treatment for 48 h. Then the glucose utilization ratio of thecal cells was detected. Meanwhile, the effects of Ber and Pue on insulin signal transmission and steroid hormones synthesis were determined by RT-PCR and Western blotting.

RESULTS(1) After being treated by Dex for 48 h, the [3-3H] -glucose uptake in cells was lowered by about half, and the glucose content in supernate increased for about 1/3. (2) The RT-PCR and Western blotting showed that levels of insulin receptor substrate-1 (IRS-1), mRNA and protein expression of glucose transporter 4 (GLUT4) lowered, peroxisome proliferator-activated receptor -gamma(PPARgamma) and cytochrome P450 17 hydroxylase (CYP17) mRNA or protein expression increased in the model cells. However, the changes of above insulin signal molecules and CYP17 expression were inversed significantly after treated with Ber and Pue for 48 h. (3) As compared with the control, in the model cells, levels of testosterone (T, microg/mL) was higher (0.82 +/- 0.20 vs 0.38 +/- 0.01, P < 0.05), while after Ber and Pue treatment it was 0.44 +/- 0.24 and 0.45 +/- 0.21 respectively, all lower than that in the model cells (P < 0.05). No significant change of serum progesterone was found in all groups (P > 0.05).

CONCLUSIONSAfter insulin resistance has been induced, the androgen synthetic capacity of thecal cells enhanced significantly. Ber and Pue could lower the degree of insulin resistance and the androgen synthesis in the model cells, displaying the favorable prospect of the two insulin sensitizing agents for the treatment of polycystic syndrome.

OBJECTIVETo study the therapeutic effects of Rhizoma Drynariae and estrogen on osteoporosis in ovariectomized (OVX) rats.

METHODSFifty-five female rats were randomly divided into 5 groups, the normal control (normal),the sham operated (sham), the model, the estrogen, and the Rhizoma drynariae (RD) groups; ovariectomized rats were used as postmenopausal osteoporosis model. The changes of morphology and dynamic parameters in different groups were determined by bone histomorphometry.

RESULTSCompared with the model group, the trabecular volume (TBV/TTV) , trabecular thickness (MTPT) and density (MTPD) in the other four groups were significantly increased, while the trabecular template spacing (MTPS) and the ratio of trabecular surface to trabecular volume (TBS/TBV) significantly decreased (P <0. 05); and the osteoid surface (TOS), single label surface [Sfract (s) ] ,double label surface [Sfract (d) ] and bone formation rate (Svf) also decreased,while osteoid maturation period (OMP) increased in the latter four groups. No significant difference of cortical width (MCW) was found between these 5 groups. Compared with the normal and sham groups, TOS, Sfract ( s) , Sfract ( d) , Svf in the estrogen and RD groups increased significantly, while OMP decreased; no significant difference was found in other parameters.

CONCLUSIONRhizoma Drynariae has the similar effect with estrogen in maintaining normal trabecular structure and connection by inhibiting the increased bone turnover of postmenopausal osteoporosis.

AIM To conduct a metabolic research for a better understanding of nephrogenic edema and to assess the integral efficacy of Mori Cortex in rat model.METHODS The serum creatinine,urea nitrogen,albumin and urinary protein levels in rats were detected.UPLC-QTOF-MS was used to detect the urine metabolites changes,Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA)were used to screen potential biomarkers,after whose quantification,Mev software was adopted for heat map draw-ing and hierarchical cluster analysis.RESULTS The model rats manifested significantly increased levels of serum creatinine,urea nitrogen and urinary protein,decreased albumin level,and an obviously excessive amino acid metabolism as well.The 41 identified biomarkers were mainly related to disturbances in phenylalanine,pyrimidine,arginine and proline,glycine,serine and threonine,tryptophan,cysteine and methionine metabolism,and biosynthesis of pantothenic acid and coenzyme A.A reversal trend in aforementioned levels of biochemical indexes and most biomarkers due to the intervention by Mori Cortex signaled an improvement in the metabolic disorder,renal dysfunction and edema.CONCLUSION The metabolic study demonstrates the pathological status of nephrogenic edema and assesses the effect of Mori Cortex from an overall perspective,highlighting a new approach for illustrating Chinese medical syndrome and the underlying mechanism in the management of traditional Chinese medicine.

Urinary brain-derived neurotrophic factor (BDNF),an ubiquitous neurotrophin,was found to rise in patients with benign prostatic hyperplasia (BPH).We hypothesized that the urinary level of BDNF could be a potential biomarker for lower urinary tract symptoms (LUTS) in patients with BPH.Totally,76 patients with BPH-caused LUTS and 32 male control subjects without BPH were enrolled.International Prostate Symptom Score (IPSS) was applied to assess the symptom severity of LUTS.Urodynamic tests were performed for the diagnosis of underlying detrusor overactivity (DO) in the patients with BPH.Urine samples were collected from all subjects.Urinary BDNF levels were measured using enzyme-linked immunosorbent assays and normalized by urinary creatinine (Cr) levels.Seventy-six BPH patients were divided into moderate LUTS group (n=51,7＜IPSS ≤ 20) and severe LUTS group (n=25,IPSS＞20) according to the IPSS.Of the 76 BPH patients,DO was present in 34 (44.7％)according to the urodynamic test.The urinary BDNF/Cr levels were significantly higher in BPH patients with moderate LUTS (8.29±3.635,P＜0.0001) and severe LUTS (11.8±6.44,P＜0.0001) than normal controls (1.71±0.555).Patients with severe LUTS tended to have higher urinary BDNF/Cr levels than patients with moderate LUTS (11.8±6.44 vs.8.29±3.635,P=0.000).The conditions of BPH with LUTS correlated with elevated urinary BDNF levels,and urinary BDNF levels were even higher in BPH-DO patients.The results of this study have provided evidence to suggest that urinary BDNF level test could evaluate the severity of LUTS in BPH patients,and BDNF level can be used as a biornarker for the diagnosis of DO in BPH patients.

OBJECTIVETo compare the clinical effects of close manipulative reduction combined with minimally invasive percutaneous plate fixation(MIPPO) and conventional open reduction and internal fixation (ORIF) for the treatment of proximal humerus fractures.

METHODSFrom April 2008 to March 2013, among the 75 patients with fractures of proximal humerus, 26 patients were male and 49 patients were female, ranging in age from 22 to 80 years; 18 patients had injuries caused by traffic accident and 57 patients had injuries caused by falling down. According to Neer classification, there were 49 cases of two-part fractures and 26 cases of three-part fractures. All the patients were divided into two groups: MIPPO group and ORIF group. There were 12 males and 21 females in the MIPPO group,including 22 cases of Neer two parts and 11 cases of Neer three parts, who were treated with close manipulative reduction combined with MIPPO. While the other 42 patients were in the ORIF group,including 16 males and 26 females. Among those patients,27 cases belonged to Neer two parts and 15 cases of Neer three parts, who were treated with ORIF. Length of the incision, blood loss, operating time, early postoperative pain(recorded by VAS), neck-shaft angle of proximal humerus and postoperative function of shoulder(recorded by Constant-Murley score, including pain, function, ROM and muscle length) were compared.

RESULTSThe mean lengths of incision were (6.74 +/- 0.38) cm in MIPPO group and (16.82 +/- 1.74) cm in ORIF group;blood losses were (110.15 +/- 29.49) ml in MIPPO group and (326.19 +/- 59.71) ml in ORIF group; operation times were (48.60 +/- 10.18) min in MIPPO group and (68.84-16.22) min in ORIF group. VAS of patients in MIPPO group on the 1st and 3rd days postoperatively were lower than those of patients in the ORIF group. The postoperative radiographs verified good position of all screws and satisfactory reduction of bone fracture reduction in both groups. All the patients were followed up,and the durig ranged from 8 to 24 months (mean 14.2 months). In the MIPPO group, there was no humeral head necrosis and all patients gained bone union; while in the ORIF group, 3 patients sustained nonunion and received reoperation for bone grafting, and 2 patients sustained humeral head necrosis. The mean Constant-Murley scores of shoulder were 88.94 +/- 2.57 in the MIPPO group and 86.00 +/- 3.36 in the ORIF group.

CONCLUSIONThe close manipulative reduction combined with MIPPO is a better choice for fixation of proximal humerus fractures, compared with conventional plate. This method possesses such advantages as a shorter incision, less disturbance of the blood supply and stable fixation of the fracture, allowing early exercise so that the function of shoulder recovers rapidly.
