EGFR/HER-2 is an attractive therapeutic target for solid tumors.Lapatinib is an orally administered dual inhibitor of EGFR/HER-2 tyosine kinases.Preclinical experiments in vitro and in vivo models indicate that lapatinib is active against various solid tumors.Phase Ⅰ trials have shown an acceptable adverse event.Phase Ⅱand Ⅲ trials demonstrate the promising results for the treatment of metastatic,refractory,inflammatory,or brain metastatic breast cancer.With the further developments of biology,the molecular targeted chemotherapy becomes a novel adjuvant therapy for advanced breast cancer patients.

Systemic lupus erythematosus(SLE)is an autoimmune disease that affects primarily women,commonly in their reproductive years but does not influence fertility.More recent prospective studies indicate that pregnancy is safe for the majority of mothers if it is planned when SLE is quiescent.In pregnant women with lupus nephritis,the outcome of the fetal and maternal is strongly correlated with lupus activity,kidney function and the presence of aPL at the time of conception.To prevent renal complications,prednisone is given after conception,and reinforcement for a few days before the estimated delivery and for a week after delivery or miscarriage with rapid tapering to maintenance levels may be suggested.Treatment of flares includes corticosteroids,hydroxychloroquine,azothioprine and cyclosporin A.Blood pressure is controlled with methyldopa,labetalol nifedipine or hydralazine.

China has high prevalence of gastric cancer, with the morbidity and mortality leading the list of malignancy. The conditions of diagnosis and treatment of gastric cancer in China fail to meet the need of a large number of patients because of restriction in re-gional development. Therefore, we are facing a very serious situation of fighting against gastric cancer. Multidiscipline, individualiza-tion, and standardization are the development tendency of diagnosis and treatment of gastric cancer. Numerous topics about gastric cancer are currently controversial and solutions to these problems depend on the development of evidence-based medicine. This re-view summarized the recent progress in the clinical methods used for stomach cancer, laparoscopic surgical techniques, diagnosis and treatment of early gastric cancer, conversion therapy of advanced gastric cancer, therapeutic strategy of esophageal-gastric junction cancer, enhanced recovery after surgery, and translational research and clinical trials of gastric cancer. Moreover, the foci and prob-lems of the diagnosis and treatment of gastric cancer were discussed to provide reference for further studies.

Objective To investigate the effects of minocycline on regional cerebral blood flow and the expression of endothe-lin-1(ET-1) in ischemic penumbra of rats after focal cerebral ischemia reperfusion injury .Methods Middle cerebral artery occlusion (MCAO) with nylon suture was used to be established as focal cerebral ischemia reperfusion mode (I/R) ,a total of 35 male Spra-geue-Dawley rats were randomly divided into 3 groups :sham-operated group(n= 10) ,model group(n= 15) and minocycline group (n= 15) .After 24 hours of I/R ,The neurobehavioral function of rats was evaluated by Longa′s test ,the regional cerebral blood flow in ischemic penumbra was assessed with laser-Doppler flowmetry .After 6 and 24 hours of I/R ,the expression of ET-1 in peri-in-farct region was measured by both immunohistochemistry and radioimmunoassay .Results Compared with sham-group ,the Longa′s test scales ,ET-1 protein expression increased and the rCBF decreased in ischemic penumbra in model group(P< 0 .05) .the Longa′s test scales ,ET-1 protein expression decreased and the rCBF decreased in ischemic penumbra in minocycline group when compared to the model group(P< 0 .05) .Conclusion Minocycline could promote neurological functional recovery of rats after MCAO ,which might be attributed to increase the cerebral blood flow and regulate the endothelin-1 expression in ischemic penumbra .

OBJECTIVE:To investigate the effects of lidocaine epidural block combined with general anesthesia on postopera-tive related indexes of lung cancer patients. METHODS:In retrospective analysis,108 patients with lung cancer were divided into observation group (56 cases) and control group (52 cases) according to anesthesia method. Both groups were given intravenous dripping of Propofol injection combined with Fentanyl injection,inhaled 1%sevoflurane for inhalation to assist anesthesia and inter-mittent intravenous drip of Vecuronium for injection to maintain muscle relaxation. On this basis,observation group was treated with epidural infusion of 2.0% Lidocaine hydrochloride injection 5 mL/h to maintain anesthesia;control group was given epidural infusion of 0.9% Sodium chloride injection 5 mL/h to maintain anesthesia. The anesthesia time,operation time,intraoperative bleeding volume,postoperative recovery time,the amount of fentanyl,propofol,vecuronium bromide and sevoflurane,the occur-rence of postoperative anesthesia complications (nausea,vomiting,dizziness,drowsiness,skin itching) and other complications (cardiac function insufficiency,cardiovascular events,atrial fibrillation,infection,transient cerebral ischemia,acute coronary com-prehensive syndrome,cerebral apoplexy)were observed in 2 groups as well as active and calm VAS score 4 h and 1,2,3,4,5 after surgery. RESULTS:The anesthesia time,operation time,intraoperative bleeding volume,postoperative recovery time,the amount of fentanyl,propofol,vecuronium bromide and sevoflurane,calm VAS score 4 h,1 d,2 d after surgery and active VAS score 4 h,1 d,2 d,3 d after surgery,the incidence of drowsiness in observation group were significantly shorter or lower than control group,while the incidence of dizziness was significantly higher than control group,with statistical significance(P<0.05). There was no statistical significance in the amount of vecuronium,calm and active VAS score in other time,the incidence of nau-sea,vomiting,skin itching,cardiac function insufficiency,cardiovascular events,atrial fibrillation,infection,transient cerebral ischemia,acute coronary syndrome and stroke between 2 groups(P>0.05). CONCLUSIONS:Lidocaine epidural block combined with general anesthesia can reduce the perioperation bleeding amount,postoperative pain,shorten postoperative recovery time and do not increase postoperative complications.

Objective To detect the level of serum melanoma-inbibiting activity (MIA) in patients with uveal melanomas, and investigate the value of MIA in diagnosing and inspecting uveal melanomas. Methods Enzyme-linked immunosorbent assay (ELISA) was used to detect the concentrations of MIA in peripheral serum of 27 patients with uveal melanoma, 6 with melanocyte tumor, 7 with other ocular tumors and 16 healthy individuals, respectively. Results The concentration of MIA in patients with uveal melanoma was significantly higher than that in the healthy ones (16 individuals) and the patients with adenoma of non pigmented ciliary epithelium (4 patients), retinoblastoma (2 patients), and retinal angioma 91 patient). The concnetration of MIA in patients with uveal melanoma without scleral infiltration or remote metastasis was obviously lower than that in the patients with scleral infiltration or remote metastasis, but didn′t differ much from which in the patients with melanocyte tumor. In the patients with uveal melanoma without infiltration or remote metastasis, there was no significant difference of MIA level between patients with spindle cell and mixed and epithelioid cell. Conclusion The level of serum MIA may be an effective index in diagnosing uveal melanoma, which can monitor the metastasis of uveal melanoma.

The main shortcomings of using electrocortical stimulation (ECS) in identifying the motor functional area around the focus in neurosurgery are certainly time-consuming, possibly cerebral cortex injuring and perhaps triggering epilepsy. To solve these problems, we in our research presented an intraoperative motor cortex functional mapping based on electrocorticography (ECoG). At first, using power spectrum estimation, we analyzed the characteristic of ECoG which was related to move task, and selected Mu rhythm as the move-related feature. Then we extracted the feature from original ECoG by multi-resolution wavelet analysis. By calculating the sum value of feature in every channel and observing the distribution of these sum values, we obtained the correlation between the cortex area under the electrode and motor cortex functional area. The results showed that the distribution of the relationship between the cortex under the electrode and motor cortex functional area was almost consistent with those identified by ECS which was called as the gold-standard. It indicated that this method was basically feasible, and it just needed five minutes totally. In conclusion, ECoG-based and passive identification of motor cortical function may serve as a useful adjunct to ECS in the intraoperative mapping.
