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.

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.

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.

3,4-Methylenedioxymethamphetamine (MDMA) is a substituted amphetamine with stimulating and hallucinogenic properties. Since MDMA induces "ecstasy" it is extensively used as a "recreational" drug. It has been well established that MDMA is neurotoxic and can result in long-term degeneration of cerebral 5-hydroxytryptamine (5-HT) nerve terminals in many species. The present study was undertaken to investigate the long-term neurotoxic effects of MDMA on cortical and hippocampal structures, by repeatedly administering MDMA in short time. Male Wistar rats were randomly assigned to control group and MDMA-treated group. MDMA (10 mg/kg) was administered to rats of MDMA-treated group, once per hour, total 40 mg/kg; rats of control group were treated with the same volume of saline. Thirty-two weeks after administering MDMA, the expression of serotonin transporter (SERT) mRNA and diazepam binding inhibitor (DBI) mRNA was detected by in situ hybridization. The expression of glial fibrillary acidic protein (GFAP) was detected by immunohistochemistry, and the degeneration of nerve terminals was demonstrated by Bielschowsky and Glee Marsland silver staining. The results showed that the expression of SERT mRNA in hippocampus decreased by 31.96%, while expression of DBI mRNA in neocortex increased by 40.51%, compared with the control group (P<0.05). The expression of GFAP in the brain tissue increased (P<0.05), while significant reduction of the nerve terminals in neocortex was demonstrated by silver staining, compared with the control group. These results suggest that the neurotoxicity of MDMA results in sustained cortical and hippocampal structural changes, which in turn result in disorder of the brain functions.

OBJECTIVETo investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.
METHODSA total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.
RESULTSShort-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.
CONCLUSIONSInonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.

OBJECTIVETo investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture.
METHODSFrom March 2009 to September 2014,18 cases of Seinsheimer type V subtrochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them, 12 cases caused by traffic accident, 5 cases by falling, 1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them, 11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur.
RESULTSThe mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection, implant failure, hip varus, external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22 ± 6.48, the result was excellent in 12 cases and good in 6 cases at the last follow-up.
CONCLUSIONUnder the principle of biological osteosynthesis, treatment of Seinsheimer type V subtrochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism, less interference of blood supply, stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V subtrochanteric femoral fracture.
