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 observe the effect of smoking cessation intervention combined with salmeterol and fluticasone pro‐pionate powder for inhalation on chronic obstructive pulmonary disease (COPD) patients with clinical symptoms and pulmonary function .Methods Totally 78 male long‐term smoking cases were randomly divided into control group(n= 40)and observation group(n=38) .The control group was treated with the ophylline sustained‐release tablets ,shah mette lo fluticasone;observation group received smoking cessation intervention .The smoking rate ,symptoms ,acute exacerbation ,life score and lung function (FEV1 ,FEV1/FVC) ,adverse reactions of two groups were observed .Results Two groups of symptoms were all improved ,but the observation group was better (P<0 .05) .FEV1 ,FEV1/FVC ,acute exacerbation ,scores were improved ,but the observation group was better(all P<0 .05);quit rates in the observation group was better than that of the control group(P<0 .05);and did not found adverse reactions .Conclusion The effect of smoking cessation intervention combined with salmeterol and fluticasone propionate powder for inhalation efficacy in the treatment of COPD is distinct ,can improve the pulmonary function and symptoms .

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 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 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.

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

Authors reviewed the present study situation of acupuncture-moxibustion theropy on osteoarthritis, and the possible principle according to the universal one have known of acupuncture and its function on other aspects especially on arthritis, so as to explore direction for further research work of clinical and principle study.

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 detect mitochondrial gene 3243 A to 1507 Chinese and analyze their clinical characteristics.Methods Classical PCR－ RFLP was used to detect the mutation and statistical analysis was performed on the data after stratification in accordance with presence or absence of diabetes.Results (1)In this study,prevalence of mitochondrial gene 3243 A to G mutation was 1.16～ 1.20％ .(2)Compared with MDM(mitochondrial diabetes),M－ NGT(normal glucose to lerance with mutation)showed no significant difference in body fat parameters,blood lipid and C－ peptide except for early onset and hearing loss(P=0.0028).(3)Compared with type 2 DM,MDM presented characteristics of early onset,weight loss,hearing loss,islet cell function decrease and maternal hereditary.Conclusion Follow－ up should be given to the carrying the mitochondrial gene 3243 A to G mutation but presenting generally normal clinical manifestation in order to give the patient in－ time diagnosis and treatment.
