Objective To investigate the effects of uterine benign disease in perimenopausal women underwent simultaneous hysterectomy and bilateral salpingectomy on pelvic pseudocyst,ovarian function and symptoms of peri-menopausal period.Methods Nine hundred and ninety-three patients with benign uterine disease underwent hysterectomy of total or subtotal uterus were selected as our subjects,who hospitalized from Jan 2005 to Dec 2009.All patients were followed up for 36 months,and 235 patients were lost.The rest 758 patients included 438 patients underwent simultaneous hysterectomy and bilateral salpingectomy,who were served as study group,and 320 patients underwent only hysterectomy were served as control group.The occurrence of pelvic pseudocyst,symptoms of peri-menopausal period and the changes of serum sexual hormone were observed.Results (1) The rate of pelvic pseudocyst was 1.6％ (7/438) in study group,which was significantly lower than that in control group (4.4％ (14/320),x2 =10.962,P =0.026).(2) Follicle-stimulating hormone (FSH) in study group at 6 months and 12 months after surgery were (17.7 ±2.3) U/L and (26.8±5.1) U/L,higher than that in control group((12.3 ±2.9) U/L,(22.4 ± 3.2) U/L,t =-1.020,-1.162,P ＜ 0.05);FSH in study group(34.0 ± 6.8) U/L was lower than that in control group (39.1 ± 4.9) U/L at 36 months after surgery,and the difference was statistically significant (t =-1.209,P ＜ 0.05).At 3 months and 12 months after surgery,luteinizing hormone (LH) in study group were (14.0 ± 2.3) U/L and (26.2 ± 3.1) U/L,higher than that in control group ((11.7 ± 2.6) U/L,(21.6 ± 1.9) U/L; t =-1.421,-0.962,P ＜ 0.05).Estradiol in study group was (90 ± 23) pmol/L,lower than that in control group((110 ± 18) pmol/L) at 24 months after surgery(t =-1.502,P ＜0.05).(3) At 6 months after surgery,the rate of perimenopausl systems was 21.7％ (95/438) in study group,higher than that in control group (14.1％ (45/320),x2 =9.102,P =0.027).However,at 24 months after surgery,the rate of perimenopausal symptoms in control group was 60.6％ (194/320),higher than that in study group (47.0％ (206/438),x2 =7.620,P =0.039).Conclusion Simultaneous hysterectomy and bilateral salpingectomy could decrease the occurrence of pelvic pseudocyst and peri-menopausal symptoms nearly equivalent to that of hysterectomy only in patients with benign uterine diseases.

Pooled literatures showed that the induced abortion in China faces many problems:the number of induced abortion remains large; most cases are young and nulliparity women; the frequency of abortion is high; and the interval between one and another abortion is short. Health promotion strategies should be applied to address these problems. It is important to increase the population's awareness of contraception,especially among nulliparity and migrant populations. Routine and effective contraceptive methods should be recommended and emphasized during induced abortion and delivery to lower the rate of induced abortion.

Objective To evaluate NucliSens HIV-1 QT(bioMerieux,Netherlands) in quantitating human immunodeficiency virus type 1(HIV-1) RNA in whole semen or seminal plasma from HIV-1-infected people.Methods Five levels of HIV-1 RNA were spiked to whole semen,seminal plasma and blood plasma samples from healthy people,and then measured by NucliSens HIV-1 QT.The same method was used to measure HIV-1 RNA in seminal plasma and blood plasma samples from 15 HIV-1 infected people.Results Nucleic acid amplification inhibitors were found in whole semen but not in seminal plasma when using NucliSens HIV-1 QT.No significant difference was found between normal seminal plasma and blood plasma samples spiked with HIV-1 RNA,and no false positive result was found in 10 normal seminal plasma samples.For 15 cases of HIV-1 infection,HIV-1 was detected in 80%(12/15) of the plasma samples and 40%(6/15) of the seminal plasma samples,with viral loads of

Objective To investigate the complications and outcomes of the treatments in the early time of posterior chamber phakic in-traocular contact lens ( ICL) implantation for the treatment of high myopia, and to analyze the causes. Methods Forty-six patients ( 92 eyes) who underwent ICL/TICL implantations were enrolled in this study. The intraoperative and the postoperative complications in 6 months were observed,at the same time also the treatments and the outcomes were observed. Results None of the patients had a pupillary block. Only 8 eyes in all the patients had an elevated IOP after peripheral iridectomy ( PI) ,and 7 eyes after the ICL implantation,the highest IOP in which was 28 mmHg. No medication was given for treatment. In the YAG PI group,the incidence rate of iris bleeding and pigment dispersion were all higher than that in the YAG PI group (P<0. 05);2 crystalline lens of different patient were damaged intraoperation. Rotation of TICL was observed in 2 eyes. Only 2 individuals of all the patients in this study had complained visual disturbances,which was shadows and glare. Visual psychological change occurred in 1 patient. Conclusion The complications in the early time after ICL implantation for treat-ment of high myopia can prevent and control,the satisfaction of the patients is high.

Objective To probe into the treatment method of filter channel obstruction after trabeculectomy. Methods Filter channel obstruction occurred in 25 eyes within one month after trabeculectomy,and they were retrospectively analyzed. According to different parts of obstruction,they were divided into three types namely inner obstruction, middle obstruction and outer obstruction. Patients with inner ob-struction were given miosis, separation of the anterior synechia, and expansion of peripheral iris incision when necessary. Patienrts with mid-dle obstruction were given reconstruction of the trabecular incision. Patienrts with outer obstruction were given conjunctiva or sclera flap dis-section within 1 month afer trabeculectomy. Results Postoperative IOP ( intraocular pressure) decreased significantly compared with preop-erative IOP. The IOP stabilized at 13~21 mmHg in the fallowing 6~12 months after operation. Conclusion Taking appropriate measures could restore the filtration function within one month after trabeculectomy when the incision adhesion was not very close.

Objective To develop a quality of life scale suitable for aphasic Chinese stroke patients by translating and evaluating the psychometric properties of the original 39-generic version of the Stroke and Aphasia Quality of Life scale (SAQOL-39g).Methods The SAQOL-39g was translated into Chinese and edited.The well edited and translated self-rated and non-self-rated scales were used to test 86 aphasia patients and their caretakers to evaluate the feasibility,internal consistency,test-retest reliability,content validity,and construct validity of the scale.Results The feasibility of the Chinese version of the SAQOL-39g scale was sufficient,with 97％ of the ques tionnaires completed.The average time taken to complete the self-report version was (21.4±4.37) minutes,with (13.25±5.61) minutes needed for the proxy version.The Cronbach's alpha values for the overall survey ranged from 0.879 to 0.950 and for the subdomains from 0.863 to 0943 for both forms,suggesting satisfactory internal reliability.The test-retest coefficients for the two forms ranged from 0.804 to 0.974 and from 0.861 to 0.987.A total of 3 common factors were extracted using factor analysis,and the cumulative contribution rate was 59.7％.The consistency between the self-reports and the proxy-reports was good.Conclusion The Chinese version of the SAQOL-39g scale demonstrates good feasibility,reliability and validity,and good consistency between the self-reported and proxy-reported versions.It seems suitable for assessing the quality of life of Chinese stroke patients with aphasia.

Objective To investigate the anticancer effects and molecular mechanism of betulinic acid (BA)on Raji cells in vitro.Methods The effects of BA on the growth of Raji cells were studied by MTT assay.Apoptosis was assessed by Annexin-V/PI double-labeled cytometry.The influence on cell cycle was studied by flow cytometer.The cyclin D3 mRNA expression was checked by Western blotting and RT-PCR techniques.Results BA showed obvious inhibition on proliferation,as well as induction potency of apoptosis on Raji cells in vitro in a time-and dose-dependent manner by Annexin-V/PI double-labeled method.With the IC_(50)value for 24 h being(39.44?0.65)?g/mL,Raji cells treated with BA showed ac- cumulation in G_0/G_1 phase and reduction in the percentage of cells in S phase.The cyclin D3 mRNA ex- pression and protein were sharply decreased in Raji cells treated with BA.Conclusion BA could inhibit the proliferation of Raji cells by regulating the cell cycle that arrests cells at G_0/G_1 phase and induces apop- tosis of Raji cells.The antitumor effects of BA may be related to down-regulation of the expression of cy- clin D3.

AIDS antiviral therapy (ART) has achieved great success.Originaly,AIDS had been regarded as a fatal disease,but it has become a kind of infectious disease that could be cured and administrated.Global HIV / AIDS cases were still up to about 38 million,but more than half have been effectively treated.In addition to drug treatment,at present,some new technologies and new methods,such as genome editing,have also been involved in the treatment of AIDS,and in the humanized animal experiment has shown very good results.There is no doubt that AIDS will eventually be stopped its epidemic.However,with the continuous development of AIDS antiviral treatment,the most fundamental problem is that HIV latent library has become increasingly prominent one,whether molecular therapy and hybrid cure have being developed for AIDS treatment,there are still such problem existence.Great efforts shoud be made to continuously search for new markers of latent viral cells and to reduce the latent pool.In addition,despite the prevention and treatment of AIDS has made great achievements,but the world still produces nearly 6000 cases of HIV/AIDS every day.Therefore,the development of safe and effective vaccine,whether in the field of prevention,or in clinical treatment,has its positive significance.
