Molecular targeted therapy (MTT) refers to a new therapy designed to interfere with a specific molecular target or signaling pathway that may have a significant influence in tumor growth or progression. MTT can inhibit cell proliferation and induce apoptosis by specific interventions in the signaling pathways of tumor cells. MTT exhibits potential as an effective treatment against cancer. This approach can improve the ability to kill cancer cells and reduce damage to normal tissues. MTT has gradually been used clinically in treating cancer and shown advantages over traditional methods. This paper reviews research progress in this targeted therapy to treat gynecological cancer.

Objective To investigate the blood-retinal barrier(BRB)function of porcine retinal pigment epithelial(RPE)cells cultured in vitro. Methods Primary porcine RPE cells were cultured,and the third generation were inoculated in a microporous filter with the filter membrane of polyvinylpyrrolidone(PVP)-free polycarbonate membrane.After 1,2,3 and 4 weeks of culture,the surface of filter membrane was observed by light microscope,and after 2 weeks of culture,the section of filter membrane was observed by light microscope and transmission electron microscope.Transepithelial electrical resistance(TER)was detected and the permeability was measured with fluorescein sodium(FS)and horseradish peroxidase(HRP). Results Primary porcine RPE cells were cultured successfully.RPE cells converged1week after inoculation; 2 and 3 weeks after inoculation,the density of RPE cells did not changed obviously; 4 weeks after inoculation,the density of RPE cells decreased.The characteristics of polarized growth of monolayer were found in RPE cells on the surface of filter membrane; 2 weeks after inoculation,the TER of RPE cells was(97.44?11.36)?/cm~2 which maintained till the 3rd week after inocubation.After incubated for 30 minutes,only 0.27% of FS and 0.17% HRP reached the inferior filter membrane,and the permeability rate of SF with low molecular weight was higher than which of HRP with high molecular weight. Conclusions The filter with PVP-free polycarbonate membrane may be used to set up the model of RPE cells with polarized growth of monolayer and investigate the barrier function of RPE cells.

Objective To investigate the effects of short-term sleep deprivation(SD)at different time during night on serum cortisol level and emotion state of healthy men,and to find out the influence of work shift onto human circadian rhythm.Methods Two periods of sleep-time were deprived in the present study:the late-night SD(permitted to sleep from 0:00 to 3:00 each day)and the early-night SD(permitted to sleep from 3:00 to 6:00 each day).Ten healthy male adults were chosen to undergo the late-night SD first,followed by normal sleeping for eight nights for washout,and then underwent early-night SD.Each SD period lasted 6 days,i.e.1 day before SD,4 days of SD and 1 day after SD for recovery.Fasting blood samples,for detection of serum cortisol,were collected at 7:00 am every SD day,and the state anxiety inventory(S-AI)scoring was done at the same time.Results The cortisol levels were lowered after 2 types of SD(P0.05).Dependability analysis showed that the cortisol level during the late-night SD period was negatively related to the SD days(r=-0.954 7,P0.05).Both types of SD could elevate anxiety scores,which positively correlated with the SD days(late-night SD:r=0.990,P

Objective To investigate the distribution features of upper limb involved nerves in patients with diabetic peripheral neuropathy (DPN).Methods The sensory nerve conduction velocity (SCV)and amplitude(SNAP),motor nerve conduction velocity(MCV)and amplitude(CAMP)of median,ulnar and radial nerves were examined in 98 DPN patients (DPN group) and 32 normal controls(NC group).The distributive ferture of involved upper limb nerves in DNP patients were analysed.Results (1) Comparing to NC group,the SCV and MCV of median,ulnar and radial nerves in DPN group were significantly slower (P

OBJECTIVE: To investigate the perioperative treatments of endoscopic sinus surgery for nasal diseases in patients with coronary heart disease after PCI. METHOD: Clinical data of 12 cases of endoscopie-assised surgery such as nasal tumors resection,functional sinus surgery,correction of deviated nasal septum,low-temperature plasma hemostasis in patients with coronary heart disease after PCI were analyzed retrospectively. RESULT: Serious bleeding did not take place with the 12 cases during surgery, and surgery progressed smoothly; one of patients had heavy nosebleed after surgery, however her condition was stable when received active treatment. Follow-up 3 months to 2 years, nasal diseases of 12 patients recovered well and symptoms were relieved; cardiovascular events such as hemorrhage, thrombosis and so on did not occur. CONCLUSION Due to physiological function of the heart dysfunction in patients with coronary heart disease after PCI,they often accompany a number of trouble issues such as medical disorders, oral antiplatelet drugs, surgery affordability loss and increase surgical risk. Correct and effective perioperative treatments, strictly surgical indications are really necessary which can keep patients safe through perioperative period.

Aim To define the effect of genistein (GST) on ceruloplasmin (CP) expression in cerebral cortex of focal cerebral ischemia male rats.Methods The effect of GST on CP expression were investigated by means of immunohistochemistry and Western blot in cerebral cortex of focal cerebral ischemia male rats.Results The expression of CP was time coursed during brain ischemia. According to the sham group,CP expression decreased in 6 h-,12 h-and 24 h-ischemia groups,and then increased gradually in 48 h-and 72 h-ischemia rats. GST weakened the ischemia-induced CP change.Pretreatment with an antiestrogen tamoxifen (TAM) could completely abolish the effect of GST.Conclusion The present results indicate that GST may inhibit the time coursed expression changes of CP and then provide neuroprotective effects by inhibiting iron related oxidative stress during brain ischemia via estrogen receptor.

OBJECTIVE:To explore loading dose simvastatin on related indicators in PCI perioperative period of patients with acute myocardial infarction. METHODS:Data of 203 acute myocardial infarction patients undergoing emergency PCI were retro-spectively collected and divided into observation group (102 cases) and control group (101 cases) by different regimens. Control group received conventional treatment for 3 d before PCI,including orally taking Aspirin enteric-coated tablet 300 mg/d,qd + Sim-vastatin tablet 40 mg/d,qd,simvastatin 40 mg/d after surgery,qd,for 4 weeks. Observation group received Simvastatin tablet 80mg 2 h before PCI,the other treatment was the same with control group. Total cholesterol(TC),triglyceride(TG),low-density li-poprotein cholesterol (LDL-C),high-density lipoprotein cholesterol(HDL-C),IL-6,IL-10,TFN-α,plasma super-sensitive tropo-nin(TNT-HSST)level,creatine kinase isoenzyme(CKMB)level,high sensitive C-reactive protein(hs-CRP)level and transami-nase level before and 24 h after treatment were observed and the incidence of adverse reactions was recorded. Meanwhile,the inci-dence of postoperative 30 d of MACE and CIN was followed-up. RESULTS:There was no significant difference in TG,TC, LDL-C,HDL-C before and after treatment(P>0.05). Before treatment,there was no significant difference in TNF-α,IL-6,IL-10, hs-CRP,CKMB,TNT-HSST levels in 2 groups (P>0.05);after treatment,TNF-α,IL-6,hs-CRP,CKMB,TNT-HSST levels were significantly higher than before(P<0.05),and TNF-α,IL-6,hs-CRP levels in observation group was significantly lower than control group,CKMB,TNT-HSST levels were significantly higher than control group;IL-10 was significantly lower than before in 2 groups,and observation group was higher than control group,with statistical significance (P<0.05). The MACE rate and CIN rate in observation were lower than control group with statistical significance(P<0.05). And no obvious adverse reaction was found in 2 groups. CONCLUSIONS:Loading dose simvastatin in PCI perioperative period can significantly reduce patients' PCI, TNF-α,hs-CRP,CKMB,TNT-HSST levels and the incidence of cardiovascular and renal adverse reactions.
