As the efficacies of chemotherapy in the treatment of advanced non-small cell lung cancer(NSCLC) have reached a plateau, the molecularly targeted therapy becomes a new method to improve curative effects.The molecular targeted drugs include epidermal growth factor receptor inhibitors, anti-angiogenesis drugs, etc.As one of the representative drugs of EGFR inhibitors, Gefitinib, has a low clinical benefit index.Erlotinib, the first EGFRTK inhibitor, can enhance the survival of patients, and may serve as a potential choice for the first-line treatment of advanced NSCLC.Bevacizumab combined with chemotherapy has shown a favorable clinical effect in the first-line treatment, and it is also the first anti-angiogenesis drug approved by the FDA that can be used in cancer treatment.These drugs, together with clinical and experimental progress in many other targeted drugs, have shown a favorable prospect for targeted drugs in the treatment of advanced non-small cell lung cancer.

The formation of carcinomas of liver, lung and kidney in rats by feeding aminopyrine (AP) plus sodium nitrite (Na NO2) in diet was investigated. 72 young Wister rats were divided into A,B,C,D group. Group A was set as control receiving basal diet and tap water. Another 3 groups were given basal diet containing AP plus Na NO2 (2g/kg each). However, group B was given tap water, group C ascorbic acid solution, group D sea buckthorn (Hippophae rhamnoides L.) juice for drinking. After 38 week's feeding, group B developed tumors in the livers (17/17), lungs (6/17) and kidneys (4/17) and the average life-span was 195 days, group D delayed the development of tumors and the average life-span was 270 days, significantly longer than that of group B (195 days, p

Objective: To observe the effects of needling Baihui (GV 20), Shuigou (GV 26) and Shenmen (HT 7) on cerebral glucose metabolism in patients with vascular dementia (VD) by cerebral functional imaging technique. Methods: Twenty-five patients with VD were divided into 5 groups (Group A, B, C, D and E) randomly. Patients in the Group A were treated by needling routine acupoints for hemiplegia (Acupoints of the three yang meridians of hand and foot), and besides the routine acupoints, patients in the Group B were treated by needling Baihui(GV 20), the Group C by Shuigou(GV 26), the Group D by Shenmen(HT 7), and the Group E by Baihui(GV 20), Shuigou(GV 26), and Shenmen(HT 7). All the patients were examined by Positron Emission Tomography (PET) to detect the cerebral glucose metabolism in the bilateral frontal lobes(orbital gyri), parietal lobes, temporal lobes(hippocampus and hippocampal gyrus), occipital lobes, thalamus, lentiform nucleus, caudate nuclei, cingulate gyms and cerebellum before treatments and after treatments. Results: After needling the routine acupoints for hemiplegia, glucose metabolism increased in lentiform nucleus and temporal lobe;needling Baihui(GV 20), increased in frontal lobe, temporal lobe and lentiform nucleus;needling Shuigou(GV 26), increased in frontal lobe, thalamus and lentiform nucleus; needling Shenmen(HT 7), increased in parietal lobe and lentiform nucleus; and needling these three acupoints, increased in frontal lobe, temporal lobe, thalamus and lentiform nucleus. Conclusion:Needling Baihui(GV 20), Shuigou(GV 26) and Shenmen(HT 7) affect glucose metabolism in different functional regions of the brain, and Baihui(GV 20), Shuigou(GV26) and Shenmen(HT 7) relate to different functional regions of the brain.

Objective To evaluate the safety and feasibility of hysteroscopy in the treatment of endogenous type cesarean section scar pregnancy (CSP). Methods Clinical data of 58 cases of CSP from August 2012 to February 2014 in our hospital were analyzed retrospectively.Thirty-one cases were treated by hysteroscopy,while 27 cases were treated by laparoscopy.The intraoperative blood loss,operation time,postoperative hospital stay,postoperative drainage of uterine cavity,β-hCG level resolution time and time to menstruous restoration were compared between the two groups. Results The intraoperative blood loss,operation time,length of hospitalization after operation,and time to menstruous restoration were statistically lower in the hysteroscopy group than those in the laparoscopy group [(109 ±59)ml vs.(143 ±63)ml,t =-2.121 ,P =0.038;(43.7 ±17.5)min vs.(100.8 ±18.8)min,t =-1 1 .974,P =0.000;(3.8 ±0.7)d vs.(4.5 ±0.6)d,t =-4.057,P =0.000;(43.8 ±3.9)d vs.(45.9 ±3.8)d,t =-2.070,P =0.043].There were no significant differences in postoperative drainage of uterine cavity and β-hCG level resolution time between the two groups [(22.1 ±2.8)ml vs.(23.6 ±3.2)ml,t =-1 .904,P =0.062;(20.5 ±7.7)d vs.(22.9 ±9.3)d,t =-1 .075,P =0.287]. Conclusion Hysteroscopy has advantages of less intraoperative blood loss,shorter hospitalization time and quicker recovery in the treatment of endogenous type CSP.

Objective To compare the early efficacy of two different ways of rehabilitation exercises in total knee arthroplasty (TKA) patients. Method From January 2011 to January 2014,136 patients having undergone TKA were randomly divided into two groups. In group A , patients exercised under the guidance with doctor. In group B, patients exercised by using continuous passive movement (CPM) machine. Compared the data from the two groups including range of motion (ROM) of the knee joint, knee function score (KFS) and circumference of the knee joint, t test of independent sample was utilized in the research. Results All patientswere followed up in 4 weeks. The ROM and KFS of Group A was significantly better than Group B (P < 0.05). The knee circumference had no statistically significant difference between two groups (P> 0.05).Conclusion Group A and B are effective methods in TKA patients in early rehabilitation training. But training under the guidance of doctor has greater advantages than CPM.

Objective To explore the clinical effect of uterine artery embolization on cesarean scar pregnancy (CSP) and curettage opportunity.Methods Sixty-three patients with CSP received curettage after uterine artery embolization with gelfoam were selected.Among of them,21 cases received curettage within 24 h after uterine artery embolization (group A); 20 cases within 1-3 d (group B);22 cases within 4-7 d (group C).The intraoperative haemorrhage,serum β-human chorionic gonadotropin (β-hCG)level resolution time,duration of hospital stay,hospitalization cost,postoperative complications were observed after the termination of the pregnancy.Results The duration of hospital stay and hospitalization cost in group A and group B were (10.5 ± 3.9),(10.2 ± 5.2) d and (7353 ± 962),(7594 ± 1032) yuan,respectively,and there was no significant difference (P ＞ 0.05).Which was lower than that in group C [(13.9 ± 5.4) d,(10 980 ± 1534) yuan],and there was significant difference(P ＜ 0.01).The intraoperative haemorrhage,serum β-hCG level resolution time and postoperative complications in group B and group C were(20.2 ± 8.8),(20.7 ± 9.3) ml and (25.9 ± 9.3),(25.7 ± 8.1) d and 40.0％(8/20),40.9％(9/22),and there was no significant difference(P＞ 0.05).But which was better than those in group A[(35.0 ± 10.7) ml,(20.5 ± 7.7) d,66.7％ (14/21)],and there was significant difference (P ＜0.01).Conclusions The treatment of curettage after the uterine artery embolization is a safe and effective method for CSP.There are fewer complications,shorter hospital stays and fewer hospitalization costs if receiving curettage within 1-3 d after uterine artery embolization.

Objective To observe the correlation of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) appearances and blood stasis syndrome in breast cancer.Methods The clinical data of 100 patients with breast cancer confirmed by operation and pathology were retrospectively reviewed.70 cases without blood stasis syndrome,30 cases with blood stasis syndrome.All the cases underwent MRI using PHILIPS Achieva 1.5T magnetic resonance scanner before surgery.Results In no blood stasis group,76.67％ inhomogeneous enhancement,edge enhancement 43.33％,spiculation proportion 50.00％,which were significantly lower than those in the blood stasis group (88.57％,75.71％,83.33％).The mass ratio of the shape between the two groups had no significant difference (P ＞ 0.05).No blood stasis group and stagnation of blood group TIC curve was mainly type Ⅳ,type Ⅲ curve ratio of no blood stasis group (3.33％) was significantly lower than blood stasis group(12.86％) (P ＜0.01).In blood stasis group,Emax/1 and tumor size were higher than without blood stasis syndrome group.the percentage of V per minute outflow of blood stasis group was lower than without blood stasis syndrome group.Conclusion The clinician should make a preliminary evaluation of the prognosis before operation,in order to timely and reasonably choose the method of integrated traditional Chinese and Western medicine.
