Objective To investigate the efficacy and toxicity of etoposide combined with prednisone (EtoP regimen) for elderly patients with unspecific peripheral T-cell lymphoma (PTCL-U) compared with the CHOP regimen.Methods 23 elderly PTCL-U patients were randomly assigned to EtoP group (n =12) or CHOP group (n =11).The curative effects and the adverse reactions were analyzed and compared between the two groups by Log-rank test and x2 test.Results The overall response (OR) rate was 66.67 ％ (8/12) in EtoP group and 63.64 ％ (7/11) in CHOP group.There was no statistically significant difference between the two groups(x2 =0.023,P =0.879).The progression-free survival (PFS) was 7.55 months in EtoP group and 4.38 months in CHOP group,statistically significant difference were observed between the two groups (x2 =23.000,P =0.011).The overall survival (OS) was 15.02 months in EtoP group and 12.26 months in CHOP group,no statistically significant difference was observed between the two groups (x 2 =14.985,P =0.597).The main side effects were bone marrow depression and digestive tract toxicity,no hematology toxicity and digestive tract toxicity of grade Ⅲ-Ⅳ occurred in EtoP group.Of those in CHOP group were 36.36 ％ and 27.27 ％.Conclusion For elderly PTCL-U patients,EtoP regimen is an effective and well tolerated therapeutic schedule.

Objective To analyze the clinical value of ovarian surgery in the treatment of primary ovarian mucinous carcinoma patients with fertility requirements.Methods 51 cases with fertility requirements with primary ovarian mucinous carcinoma who received surgical treatment were analyzed.The postoperative serum follicle stimulating hormone (FSH) and luteinizing hormone (LH),estradiol (E-2),anti Mullerian hormone (AMH) were deteced.The patients were followed up for 3 years,the survival rate and fertility were observed.Results Of 51 patients underwent surgery,postoperative 7d,14d,the FSH,LH levels in serum were higher than before operation (F=24.198,21.554,all P<0.05),E-2,AMH,PSV values were lower than before operation (F=24.407,35.028,11.064,all P<0.05).During the follow-up period to June 2015,there were 4 patients died of tumor recurrence,2 patients were lost to follow-up,45 patients survived,the survival rate was 88.23%.Of 45 patients survived,41 patients were normal menstrual cycle,menstruation,menstrual cycle 26-31 d,average (28.2±2.2)d;4 patients with irregular menstruation.Married women in the follow-up of 44 cases,including 28 patients with successful pregnancy,the pregnancy rate was 63.64%,there were 4 cases of spontaneous abortion,pregnancy in 3 patients because of abortion,pregnancy examination found 17 cases of abnormal pregnancy,4 cases of premature delivery.Conclusion In patients with primary ovarian mucinous carcinoma,it is feasible to use fertility preserving function,and the pregnancy rate is high,but the follow-up and monitoring should be strengthened to avoid the bad prognosis.

1-(2,6-Dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride(DDPH) caused parallel rightward shifts of the phenylephrine(Phe) concentration-contractile response curves and did not suppress the maximal contractile response to Phe (pA2=7.24) in isolated rabbit urinary bladder smooth muscle. DDPH decreased the parameters of cystometry in urethane-anesthetized rats. Thirty minutes after DDPH (25 and 50 mg*kg-1 ig) administration, bladder capacity, voiding pressure, voiding threshold pressure were significantly decreased. With the observation of light-microscope and electron-microscope technique, DDPH (25 and 50 mg*kg-1*d-1 ig for 4 weeks) also inhibited the development of testosterone propionate-induced benign prostatic hyperplasia in rats. The results indicate that DDPH may inhibit benign prostatic hyperplasia and improve the urinary flow.

Objective To compare the clinical effect of the primary total hip replacement (THR)and the secondary THR after failed internal fixation in elderly patients with displaced femoral neck fracture,so as to investigate the optimal treatment for displaced femoral neck fractures in elderly patients.Methods From January 2006 to December 2012,22 patients treated with a secondary THR after failed internal fixation were chosen as the observation group and 30 patients treated with a primary THR were chosen as the control group,the operation time,blood loss,postoperative Harris scores for hip joint and health-related quality of life (~ index score) were observed and analyzed in two groups.Results Both of the groups were followed up successfully and each of the groups had 1 patient died.There were no joint infection,re-operations and any other complications in both groups.The operation time in observation group was longer than that in control group [(114.82 ±32.13) min vs.(90.63 ± 16.24) min],blood loss was more than that in control group [(551.73 ± 241.62) ml vs.(314.46:± 156.72) ml],there was significant difference (P ＜ 0.05).But the Harris score and KPS index score between two groups had no significant differences (P ＞ 0.05).Conclusion The primary THR in elderly patients with displaced femoral neck fracture has lower risk in operation tocompare with the secondary THR after failed internal fixation,but the two ways are similar in the hip joint function recovery and improve patients quality of life.

Objective : To investigate the fertility level of registered population in Baoshan District, Shanghai Municipality and the incidence of adverse birth outcomes of live births from 2013 to 2022, so as to provide the evidence for improving maternal and child health care strategies. Methods: The data pertaining to live births registered in Baoshan District from 2013 to 2022 were collected through the Shanghai Birth Medical Information System, including the basic information of live births and maternal fertility. The indicators such as fertility level, parity, birth age and incidence of adverse birth outcomes of live births were descriptively analyzed. The trend of crude birth rate and total fertility rate was analyzed by annual percent change (APC). Results: A total of 56 719 live births were registered in Baoshan District from 2013 to 2022. The crude birth rate was 6.54‰, the total fertility rate was 31.78‰, and the sex ratio at birth was 105.61. The crude birth rate showed a downward trend from 2016 to 2022 (APC=-11.054%, P<0.05), and the total fertility rate showed a downward trend from 2017 to 2022 (APC=-10.377%, P<0.05). The proportion of second parity and above showed an increasing trend from 2013 to 2017 (P<0.05) and a decreasing trend from 2017 to 2022 (P<0.05). The maternal childbearing age showed an increasing trend from 2013 to 2022 (P<0.05), the incidence of premature infants and low birth weight infants showed an increasing trend (both P<0.05). The incidence of premature infants and low birth weight infants increased with the rising childbearing age (both P<0.05). Conclusions The fertility level in Baoshan District was relatively low from 2013 to 2022. The proportion of second parity and above showed an upward trend followed by a downward trend. The incidence of premature infants and low birth weight infants increased with the rising childbearing age.

Time perspective therapy (TPT) which belongs to positive psychology is a new psychological intervention to post-traumatic stress disorder (PTSD).A large number of studies abroad have testified that TPT is very long-term effective,what′s more, TPT has been popularized and improved by foreign scholars but not been applied in China.TPT has been a study issue in mental and psychological fields,but that how to apply TPT rightly in China needs to explore.Therefore, this paper systematically introduced and analyzed TPT theory, the problems of applying TPT and the enlightenment of nursing PTSD,so as to help Chinese scholars apply TPT to solve problems and status of nursing PTSD in China.
