Objective To investigate the clinical efficacy and safety of medroxyprogesterone acetate in the treatment of endometrial atypical hyperplasia patients.Methods 98 cases of endometrial atypical hyperplasia patients were randomly divided into study group and control group with 49 cases in each group, study group were treated with medroxyprogesterone acetate treatment, and control group were given estradiol valerate tablets treatment.Two groups of patients were treated for 3 ~6 menstrual cycles, and clinical curative effect of two groups was compared.Results After treatment, the PBAC score and endometrial thickness inspection results in study group and control group respectively decreased significantly compared with before treatment (P<0.05), and the above indexes in study group were significantly lower than control group (P<0.05).After treatment, the hemoglobin value in two groups at 1st, 2nd, 3rd month after treatment was significantly higher than before treatment (P<0.05), and hemoglobin values at 1st, 2nd month after treatment was significantly higher than control group (P<0.05).The effective rate of study group (95.92%) was significantly higher than that of control group (81.63%, P<0.05).The recurrence rate during six months was 4.08% in study group, 8.16% in control group, and the difference was not statistically significant.Conclusion The efficacy of medroxyprogesterone acetate is better than estradiol valerate tablets in the treatment of endometrial atypical hyperplasia patients, which is safe and effective.

AIM:To observe the clinical characteristics of palm video keratitis and analyze the pathogeny. And to explore methods to cure and prevent it.
METHODS: A total of 591 patients were randomly selected. Firstly, the frequency of staring at palm video equipment were investigated and break-up time of tear film with slit-lamp were observed. Then the data were calculated and the clinical characteristics were described. Finally, the correlation between incidence rate and the two factors were analyzed by SPSS13. 0 respectively.
RESULTS:The incidence rate of palm video keratitis increased along with the frequency of staring at palm video equipment and decreased along with break- up time. There was significant relationship between incidence rate and the two factors respectively.
CONCLUSION:It is the most important pathogeny that staring at palm video equipment ahead and down for a long time which cause the change of tear film. That can reduce the frequency of using palm equipment and drop artificial tears to prevent and cure the disease.

ObjectiveTo compare the different efficacy between invasive positive pressure ventilation andnoninvasivepositivepressureventilationofacuteexacerbationchronicobstructivepulmonary disease.Methods Patients with acute exacerbation chronic obstructive pulmonary disease were randomly divided into invasive positive pressure mechanical ventilation ( IPPV ) group ( n =35 ) and noninvasive positive pressure mechanical ventilation (NPPV)group (n =37 ),and clinical data before and after treatment were analyzed retrospectively.ResultsAfter 2 hours of invasive positive pressure mechanical ventilation,pH,arterial oxygen partial pressure( PaO2 ),arterial carbon dioxide partial pressure ( PaCO2 ),heart rate ( HR ),respiratory rate(RR),Glasgow coma scale(GCS) score were better than those before treatment[ pH:(7.35 ± 0.05)vs ( 7.23 ± 0.02 ) ; PaO2:( 92.4 ± 14.5 ) mm Hg vs ( 51.3 ± 9.4 ) mm Hg; PaCO2:( 56.0 ± 7.7 ) mm Hg vs( 82.6 ±8.1)mm Hg;GCS:(10.5 ± 1.1)points vs(8.5 ± 1.2)points;HR:(110 ± 12) times/min vs(131 ± 19) times/min ; RR:( 26 ± 4) times/min vs ( 35 ± 8 ) times/min ; P ＜ 0.05 or P ＜ 0.01 ].But in NPPV group,only the PaO2,HR,RR were better than those before treatment [ PaO2:( 78.6 ± 8.8 )mm Hg vs ( 53.1 ± 8.9 ) mm Hg; HR:( 110 ± 24) times/min vs ( 128 ± 23 ) times/min ; RR:( 26 ± 5 ) times/min vs ( 36 ± 9 ) times/min; P ＜ 0.05 ].And after 6 hours,pH,PaCO2,GCS score were significantly better in NPPV group [ pH:( 7.35 ± 0.03 ) vs ( 7.25 ±0.01 ) ;PaCO2:(59.0 ±6.3) mm Hg vs(79.8 ±7.0) mm Hg;GCS:( 10.6 ± 2.0) points vs( 8.5 ±2.5) points;P ＜ 0.05 or P ＜ 0.01 ].There was no difference on the days in ICU [ ( 15 ± 4) d vs ( 14 ± 4 ) d,t =1.102,P ＞0.05 ],the duration of mechanical ventilation[ ( 168 ± 25 )d vs( 170 ± 23 )d,t =1.214,P ＞ 0.05 ],the mortality in ICU (22.8％ (8/28) vs 21.6％ (8/37),x2 =0.016,P ＞ 0.05) between IPPV group and NPPV group.ConclusionIPPV can improve the situation of AECOPD quickly,but in NPPV group some patients need intubation.However,there was no significant difference on the days in ICU,the duration of mechanical ventilation,the mortality in ICU between IPPV and NPPV.

Cytochrome P450 (CYP) is a complex gene superfamily of proteins that metabolizes a myriad of endogenous and exogenous substrates. Liver-enriched transcription factors (LETF) play a role in the constitutive and tissue-specific expression of hepatic genes. In this review, six families of LETF that play a role in the tissue-specific, developmental, sexual and temporal regulation of CYP are discussed.

Fabry disease is an inherited metabolic disease, resulting from a deficiency of the enzyme a-galactosidase A activity. Principal clinical manifestation of Fabry disease was limb pain episodes, angioceratoma, and progressive damage of heart,brain, kidney. Although Fabry disease cannot be cured at present,early diagnosis and enzyme replacement therapy can change the prognosis completely.

Objective To examine the inhibitory effect of IL-2-PE40 on the mouse corneal allograft rejection. Methods A mouse corneal graft model was set up by using C57BL/6 mice as donors and Balb/c mice as recipients. In the treatment group, IL-2-PE40 (0.6 μg/g body weight) was intraperitoneally injected from the day of surgery every 12 h until rejection happened. In the control group, the equal volume of PS was injected intraperitoneally at the corresponding time points. The transplanted cornea was observed under slit-lamp twice a week and the transplanted corneal opacity and neovascularization were rated according to Horis grading standards. It led to the determination of rejection response. The survival of transplanted cornea was regarded to be stopped when the rejection occurred. The operated eyes were observed historically on the 10th, 15th, 25th and 35th day after the surgery, and the peripheral blood was collected for measurement of T cell subgroups and T lymphocyte colonies. Results The survival time of cornea in the treatment and control groups was (30.2±2.9) days and (15.1±2.1) days respectively. In the control group, rejection occurred on the 15th day after the surgery, CD4~+ cells started rise right after the surgery and increased most obviously on the 15th day [(63.9±4.0)%] and decreased afterwards. CD4~+ cells in the treatment group were increased slightly [(42.6±4.0)%] on the 15th day. The number of CD4~+ cells in the treatment group was obviously less than in the control group (P<0.01). No significant changes in CD8~+ cells were observed in both groups. The number of T lymphocyte colonies in the control group was increased at the beginning and dropped then. No obvious change was found in the treatment group. The number of T lymphocyte colonies in the treatment group was significantly less than in the control group (P＜0.01). Conclusion IL-2-PE40 is a highly specific immunosuppressive agent. It can delay the development of corneal graft rejection and reduce the percentage of T-helper cells significantly. It also works to weaken the forming capacity of the peripheral T lymphocyte colonies.

Pathologic pain is a common suffering and does great harm to people health. Therefore it is important to search some suitable targets for pain management. Recently it has been shown that activated inflammatory cells and glia are strongly implicated in the pathologic pain. Cyclic 3',5'-adenosine monophosphate,a universal intracellular second messenger,has been proven to inhibit the activity of inflammatory cells and glia by enhancing its activity,further to control pathologic pain. This review presents the current understanding of the underlying mechanisms for the inhibitive effect of cAMP signal pathway in inflammatory cells and glia,and the effect of phosphodiesterase inhibitors used for relieving pathologic pain.
