Objective To study the effect of preventive treatment of primary dysmenorrhea (belonging to syndrome of stagnation of Qi and blood) by using “acupunctureof regulating Qi and relieving pain”. Methods 60 patientsfrom January 2013 to November 2013(in acupuncture and moxibustion department of Beijing Chinese Medicine Hospital affiliated to Capital Medical University), with Qi and blood stasis type of primary dysmenorrhea were randomly divided into a treatment group (formula of regulating Qi and relieving pain)and a control group(routine acupuncture group), 30 cases in each group. The treatment group was treated with acupuncturing onlieque,fenglong,ligou as the main points while the control group withhegu, diji, sanyinjiao as the main points. All patients received 3 times of acupuncture treatment at the beginning of the week before menstruation and were treated three menstrual cycles altogether. VAS scores, length of pain and CMSSⅡscores during baseline period and three menstrual cycles were observed in order to determine the clinical effects. Results VAS score, length of pain and CMSSⅡscores were significantly reduced than before(P<0.01)[the treatment group in cycle 1 was(5.05±0.98), (14.03±8.37)h, (12.77±3.64), in cycle 2 was (4.18±0.87), (12.53±7.13)h, (12.07±3.69), in cyce 3 was(3.43±0.82), (11.50±6.88)h, (11.33±3.64);the control group in cycle was 1(5.00± 1.05), (14.97±9.19)h、(14.40±3.5), in cycle 2 was(4.25±0.93), (13.83±9.12)h, (13.70±3.43), in cycle 3 was(3.73±0.91), (12.63±9.02)h, (13.03±3.41)];Compared with the control group, VAS scores intreatment groupdecreased more significantly (P<0.05), while reduced level of pain time and CMSSⅡscores showed no significant difference between the two groups (P>0.05). Conclusion Acupuncture of regulating Qi and relieving painmay effectively relieve pain, shortenlength of pain, improve symptoms of dysmenorrhea severity. It has a significant preventive treatment for Qi and blood stasis type of primary dysmenorrhea.

Objective To explore changes of serum fibroblast growth factor 2 (FGF2) levels after treatment with imatinib mesylate in patients with unresectable or metastatic gastrointestinal sromal tumor.Methods Serum FGF2 levels (with ELISA) were determined in 27 patients with unresectable or metastatic gastrointestinal stromal tumor both before and after treatment with imatinib mesylate.Results Before treatment with imatinib mesylate,of 27 cases of unresectable or metastatic gastrointestinal stromal tumor,17 cases (63.0 ％) were found positive for serum FGF2,after treatment with imatinib mesylate,9 cases (33.3 ％) were found positive for serum FGF2 (P ＜ 0.05).Using imatinib mesylate for 3 months,complete remission rate was 0,partial remission rate was 51.9 ％ (14/27),stable disease rate was 48.1％ (13/27) and progressive rate was 0.Conclusion Patients with unresectable or metastatic gastrointestinal stromal tumor have elevated serum FGF2 levels.Imatinib mesylate treatment can reduce serum FGF2 levels in patients with unresectable or metastatic gastrointestinal stromal tumor.

ObjectivesTo explore the serum insulin-like growth factor-1 (IGF-1)levels in the patients with unresectable or metastatic gastrointestinal stromal tumors before and after imatinib treatment and to discuss its clinical significance.MethodsThe serum samples of27 patients with unresectable or metastatic gastrointestinal stromal tumors were collected before imatinib treatment(before treatment group) and three months after imatinib treatment(after treatment group).The other serum samples were collected from 20 healthy volunteers who were accepting health examination (control group). The serum IGF-1 levels of the samples were determined by enzyme-linked immunosorbent assay (ELISA).ResultsThe mean serum IGF-1 levels were significantly higher in before treatment group than in control controls[(463.61±120.98)ng/ml vs.(115.75±39.27) ng/ml, t=12.355,P=0.000)]. Three months after imatinib treatment,the mean serum IGF-1 levels were significantly lower in after treatment group than in before treatment group [(244.64±100.11)ng/ml vs.(463.61±120.98) ng/ml, t=7.582,P=0.000].ConclusionsSerum IGF-1 levels may help to judge therapeutic effect,progression,recurrence or metastasis of the gastrointestinal stromal tumor.

Purpose:To study the capacity of hematopoietic growth factors combinations(IL 3,G CSF,GM CSF) for inducing CD34 + cells to proliferate and differentiate committedly to granulocytes. Methods:CD34 + cells were isolated from peripheral blood by using a high gradient magnetic cell sorting sysem(MACS),and expanded with IL 3、G CSF and GM CSF in a liquid culture system.Colony forming cells and CD34 + cell ratio were studied by colony forming assays and FACS. Results:The combinations of IL 3,G CSF and GM CSF increased the total cell number by 56 fold and 110 fold, increased CFU GM by 8.44 fold and 35.08 fold respectively at the 3rd and the 7th day after culturing ,and the ratio of CD34 +cell decreased during the culture.Conclusions:It is possible to induce CD34 +cells to proliferate and differentiate committedly to granulocyte lineage.

0.05). Women with triple negative breast cancer experienced more lymph node metastases (71.9%︰58.5%,P=0.034),with the higher percentage of more than 10 lymph nodes metastases(26.0%)as compared with Her-2-overexpressing breast cancer (12.2%,P=0.034). A higher percentage of histological grade 3 was identified in triple-negative (67.7%)than in Her-2-overexpressing breast cancer(42.1%,P0.05). However,significantly poorer 5-year DFS was seen in patients with triple negative phenotype (61.85 months)than with Her-2-overexpressing phenotype (78.69 months,P=0.047). Conclusion Triple-negative breast cancers were more aggressive,and these women had poorer DFS comparing with Her-2-overexpressing ones.

Objective To evaluate the diagnostic value of dermoscopy and reflectance confocal microscopy (RCM) alone or in combination for melanocytic nevus.Methods A total of 37 patients with clinically diagnosed melanocytic nevus were collected.Skin lesions were firstly examined by dermoscopy and RCM,then were resected to be subjected to histopathological examination for final diagnosis.The imaging features of melanocytic nevus were summarized.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of different skin imaging techniques were calculated,and the consistency was analyzed between skin imaging techniques and histopathological examination.Results Based on the dermoscopic and RCM findings,2 kinds of nevus cells with different morphological features were observed in the dermis of intradermal nevus.One kind of nevus cells was characterized by a nonfusional,highly-refractive round structure in the papillary dermis under RCM,and by a brown or light brown homogenous pattern under dermoscopy,which was observed in 5 skin lesions.The other kind of nevus cells appeared as irregular,highly-refractive cell clumps in the papillary dermis under RCM,and by a cobblestone or globular pattern under dermoscopy,which was observed in 31 skin lesions.For the diagnosis of melanocytic nevus,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of RCM combined with dermoscopy were 91.7％,87.5％,90.9％,97.1％ and 70％ respectively,those of RCM were 86.1％,75％,84％,93.9％ and 54.5％ respectively,and those of dermoscopy were 77.8％,87.5％,75％,96.3％ and 41.2％ respectively.All the diagnostic indices of RCM combined with dermoscopy were higher than those of RCM or dermoscopy alone,except that the specificity was equal to that of dermoscopy alone.RCM showed higher sensitivity,accuracy and negative predictive value,but lower specificity and positive predictive value compared with dermoscopy.There were no significant differences in the diagnostic yield in melanocytic nevus between RCM combined with dermoscopy or RCM alone and histopathological examination (x2 =0.25,0.57,P =0.63,0.45,Kappa value =0.72,0.53,respectively).However,a significant difference in the diagnostic yield in melanocytic nevus was observed between dermoscopy and histopathological examination (x2 =5.81,P =0.012).Conclusion RCM combined with dermoscopy shows higher diagnostic accuracy for melanocytic nevus compared with RCM or dermoscopy alone.

Objective To evaluate the diagnostic yield and safety of transbronchial lung biopsy (TBLB) under virtual bronchoscopic navigation (Direct Path), endobronchial ultrasonography with a guide sheath (GS) and rapid on-site evaluation using an ultrathin bronchoscopy (UNRE) for bacterial infection located in the peripheral third of the lung field. Methods Ninety-seven patients with bacterial infection, which located in the peripheral third of the lung field on CT images, were ran-domly assigned to UNRE (n=49) or non-UNRE (NUNRE, n=48) groups, who were treated in General Hospital of Tianjin Medical University between April 1, 2014 and March 31, 2015. The TBLB guided by UNRE was performed in two groups. The diagnostic yield, safety and complication rate were compared between two groups. Moreover, the differences of autofluo-rescence intensity of alveolar macrophage in alveolar lavage fluid were compared between two groups of patients. Results The diagnostic yield was significantly higher in UNRE group than that of NUNRE group (81.6% vs 56.2%, χ2=7.313, P <0.01). The diagnostic yield was higher in UNRE group with bronchus sign compared to that of NUNRE. All patients had a mild bleeding at the time of biopsy. There were no hemoptysis, pneumothorax or other serious complications. The autofluores-cence intensity of alveolar macrophage was different in different levels of infection in patients. Conclusion The procedure of UNRE has higher diagnostic rate and fewer complications. The careful selection of suitable cases can further improve the diagnostic accuracy. The autofluorescence intensity of alveolar macrophage in alveolar lavage fluid indicates the severity of infection in patients.
