Objective To analyze the clinical features and prognostic factors of lymphoma.Methods The clinical data,pathologic data and survival state of 253 patients with lymphoma in Qinghai were retrospectively studied.The survival differences of patients with different clinical characteristics and laboratory tests were analyzed using Kaplan-Meier method.The prognostic factors of lymphoma were analyzed by Cox proportional hazards regression model.Results Among all of 253 cases of lymphoma,males were in the majority (male∶female =1.56∶1).The median age of patients was 48 years old.There were two peaks of about 40 years old and 60 years old in age of onset.The nodal lymphoma (56.13 ％) was more commonly than the extranodal lymphoma (43.87 ％).The more common extranodal lymphomas were found in the nasopharynx and gastrointestinal tract.Among all cases,40 cases (15.81％) were confirmed to be Hodgkin lymphoma (HL),of which,the commonest subtype was nodular sclerosis (72.5 ％).While 213 of 253 cases (84.19 ％) belonged to non-Hodgkin lymphoma (NHL),of which,B-cell lymphoma was 148 cases (69.48 ％).Overall,three subtypes including diffuse large B-cell lymphoma (39.91％),follicular lymphoma (12.21％) and peripheral T-cell lymphoma (9.39 ％) were the commonest subtypes among all cases.Univariate analysis showed that the clinical stage,B symptoms,Hb concentration,serum LDH level,international prognostic score (IPI) and treatment programs were related to the prognosis of NHL (P ＜ 0.05).However,the Cox regression multivariate analysis showed that only the clinical stage,IPI and treatment programs,not B symptoms,Hb concentration and serum LDH level,were closely related to the prognosis of NHL (P ＜ 0.05).Conclusions In Qinghai area,there are two peaks of about 40 and 60 years old in the age of onset of lymphoma.The nodal lymphoma is more than extranodal lymphoma.B-cell lymphoma is more common.IPI could be as an independent prognostic factor and might be used to estimate the prognosis of NHL.

Objective To investigate the typing, staging and therapeutic outcome of intrahepatic cholan-giocarcinoma (ICC). Methods The clinical data of 60 ICC patients who were admitted to the Renji Hospital of Shanghai Jiaotong University from January 2000 to December 2008 were retrospectively analyzed. ICC was classi-fied according to the type and TNM staging proposed by the Liver Cancer Study Group of Japan (LCSGJ). The relationships between typing, staging, surgical procedures and therapeutic outcome were investigated, as well as the relationship between the LCSGJ staging system and UICC staging system. Results The 1-, 3-, and 5-year survivals of the 60 ICC patients were 44% (23/52), 19% (10/52) and 10% (5/52), respectively. The median survival time for patients with radical resection (n =30) , liver transplantation (n = 10), palliative surgery (n = 11) and exploratory laparotomy (n=9) were 13, 3, 3 and 1 months, respectively. The radical resection rates for mass-forming type, periductal-infiltrating type, intraductal growth type and mixed type were 23/31, 9/15, 5/6 and 3/8, respectively. There were significant relationships between tumor type, degree of differentiation and prog-nosis (χ2 = 8. 308, 10. 009, P < 0. 05), and between tumor type and lymph node metastasis (χ2 = 13. 261, 5.702, P <0.05). There was no significant difference in survival time between patients with different pathological types, but the prognosis of patients with mucinous adenocarcinoma was better than that in the other types, with a median survival time of 20months. The median survival time of patients in LCSGJ stage Ⅳ was 3. 0 months, which was significantly longer than that in UICC stage Ⅳ (χ2 =3. 877, P <0. 05). Tumor staging was intimately related to the macroscopic type χ2 =8.288, P <0. 05). Conclusions The prognosis of ICC is poor. The typing and staging of LCSGJ is concise and practical, which is helpful in guiding treatment and evaluating progno-sis. Surgical treatment should be applied to mucinous ICC, and liver transplantation is not recommended for the treatment of ICC.

Primary dysmenorrheal is one of the most common diseases in gynecology,which seriously affects the physical and men-tal health of women, therefore, the effective prevention and treatment of primary dysmenorrheal is a problem in medical field. The etiol-ogy of primary dysmenorrheal is very complicated, and in recent years, there are more and more domestic and foreign scholars studying on its pathogenesis and treatment. Modern medicine has some shortcomings in the treatment of dysmenorrheal including side effects and so on. Traditional Chinese medicine has unique advantages in the treatment of primary dysmenorrheal. Combined with the recent rele-vant reporters, the article reviewed the pathogenesis of primary dysmenorrheal from both traditional Chinese medicine and modern medi-cine aspects, and the research progress in traditional Chinese medicine treatment of primary dysmenorrheal was also reviewed to provide better guidance for the treatment of primary dysmenorrheal.

Objective To study effects of Rupixiao granules on contraction of uterus of mice in vitro. Methods Mouse model with isolated uterine contraction was established. The mice pretreated with estradiol benzoate were sacrificed and then the uteri were taken out. The normal contractions were recorded by the biological function system. Effects of 10, 20, 30, 40, 50, 60 mg.mL-1 Rupixiao granules on spontaneous and oxytocin-induced (5 U.L-1) uterine contractions were recorded,inhibition of Rupixiao granules on mean constriction amplitude,constriction frequency and contraction activity of pitocin-pretreated uterus was observed and the inhibition rates were calculated. Results Compared with the baselines, the amplitude, frequency, activity of spontaneous uterine contraction were significantly down-regulated by Rupixiao solution at a range of 10-60 mg.mL-1 ,as well as it could inhibit oxytocin-induced spasmodic contraction of isolated uterus at 10-50 mg . mL-1 ( P<0. 01 ) . Conclusion The Rupixiao granules inhibits spontaneous contraction of isolated mouse uteri and oxytocin-induced spasm of uterine smooth muscle in vitro.

[ ABSTRACT] AIM:To investigate the expression relevance of transcription factors GATA-1 and GATA-2 in the bone marrow CD71 +cells of a high-altitude polycythemia (HAPC) rat model.METHODS:Male SD rats (n=48) were randomly divided into normal control group and HAPC model group .HAPC model was established at an altitude of 4 300 m in the natural environment and verified by the morphology and quantity of the bone marrow cells and hematologic parameters detection .A relative change in the trend of bone marrow CD 71 +cell numbers was detected by flow cytometry analysis .The expression of GATA-1 and GATA-2 at mRNA and protein levels in the CD 71 +cells was examined by RT-qPCR and West-ern blot .CD71 +cells were cultured under hypoxic condition and transfected with the optimal interference sequence of GA -TA-1shRNA1 for 96 h.The expression of GATA-1 and GATA-2 at mRNA and protein levels was detected by RT-qPCR and Western blot .RESULTS:The establishment of the animal model with HAPC was successful as the bone marrow smears and the hematologic parameters showed compared with the control .The quantity of the bone marrow CD 71 +cells of HAPC rats were significantly increased and the expression of GATA-1 at mRNA and protein levels in the CD 71 +cells were higher than those of the control .The expression of GATA-2 at mRNA and protein levels was similar to that of the control .The correla-tion analysis showed that the expression of GATA-1 was negatively correlated with that of GATA-2 in the control, while no obvious correlation between them was observed in the HAPC rats .The expression of GATA-1 at mRNA and protein levels in HAPC group was lower than that in control group after interfered by GATA-1 shRNA1 for 96 h, but no obvious diversity of GATA-2 expression between the 2 groups was observed .CONCLUSION:GATA-1 and GATA-2 are abnormally expressed and their negative correlation is destroyed in HAPC , which may be one of the pathogenesis of HAPC .
