[Results] Within two years after treatment, compared with the control, in the Chinese Medicine group, the cases of recurrence of Posner-Schlossmann syndrome were obviously decreased. [Conclusion] Chinese medicine with the effect of tonifying the liver and kidney, nourishing yin and suppressing hyperactive yang shows definite effect on postoperative Posner-Schlossmann syndrome, it can decrease the occurrence frequency of number.

[Objective] To evaluate the effect of Ginkgo biloba extract on optic nerve in progressive normal-tension glaucoma patients. [Methods] 60 cases of patients suffered from controlled normal-tension glaucoma were randomly divided into control and treatment groups, 30 cases in each respectively. The patients in the control group received the conventional treatment(eye drops or surgical treatment), additionally the patients in the treatment group received Ginkgo biloba extract(twice a day ,1ml each time). 5 months was a therapeutic course, after 3 therapeutic courses the best corrected visual acuity, ocular hemodynamics, visual field, retinal nerve fiber layer thickness and optic disc data were detected and statistically studied. [Results] There was no significant difference in the best corrected visual acuity between control group and treatment group( P>0.05). The end diastolic velocity(EDV), peak systolic velocity(PSV) were increased significantly and resistive index(RI) was decreased significantly in treatment group after treatment( P<0.05), while the EDV, PSA, RI in control group before and after treatment were without significant differences( P>0.05). The mean visual field defects(MD) in treatment group after treatment were much lower than the control group( P<0.05). The reduction trends of the retinal nerve fiber layer thickness and rim area in treatment group after treatment were slower than control group significantly decreased( P<0.05). [Conclusion] Ginkgo biloba extract can improve the ocular hemodynamics, delay the deterioration of the best corrected visual acuity and visual field damage, extend the losing time of visual retinal nerve fiber layer thickness and rim area. It has protective effect on optic nerve in normal-tension glaucoma.

Objective:To explore the urodynamic characteristics of bladder function in patients with abnormal urination after radical hysterectomy of cervical cancer.Methods:In a prospective self-controlled study, a total of 84 patients with cervical cancer and clinical stage of ⅠB to ⅡA, meeting the preoperative inclusion criteria in our hospital from January 2016 to June 2018 were enrolled.All patients were tested for urodynamic testing 1 week before and 6 months after surgery.Patient bladder function status was observed and evaluated before and after surgery and urodynamic examination results were analyzed.Results:Of 84 study cases, the 58 patients developed abnormal urination after radical surgery, there were no urination abnormalities in 26 cases.There was no significant difference in age, clinical stage and pathological diagnosis between patients with and without urination abnormalities.Abnormal urination after radical surgery included difficulty in urinating(55%), frequent urination with a feeling of urination not complete(34%), stress urinary incontinence(7%), and urinary incontinence(4%). Among the 26 patients without urination abnormalities after radical surgery, only one case showed an abnormal urodynamic examination(abnormal bladder sensation). In patients without abnormal urination after surgery, differences in the urodynamic examination findings between pre-and post-surgery were not statistically significant(all P> 0.05). At the same time, in all cases of abnormal urination after radical hysterectomy of cervical cancer, 43 patients(74%)with bladder dysfunction had normal urination pattern before operation, but after operation, the urination abnormality required abdominal pressure.Of the patients with bladder dysfunction after surgery, the maximum flow rate(Qmax)was(12.9±10.3)ml/s, the average flow rate(Qave)was(6.0±4.2)ml/s, the voided volume was(148.0±36.8)ml, voiding time was(32.9±22.1)s, maximum flow time was(11.4±5.0)s, postvoid residual urine was(260.2±219.2)ml, maximal detrusor pressure was(12.1±8.9)cmH 2O, bladder compliance was(16.1±4.3)ml/cmH 2O, normal desire to void was(354.5±204.3)ml, maximal capacity was(587.4±152.5)ml, maximum urethral pressure was(97.6±33.1)cmH 2O, maximum urethral closure pressure was(89.9±36.4)cmH 2O, and function urethral length was(29.6±6.5)mm; In comparison, the above indexes-corresponding values at 1 week before surgery were respectively as follows: the Qmax was(25.1±11.4)ml/s, the Qave was(11.4±6.6)ml/s, the voided volume was(318.6±96.4)ml, voiding time was(29.2±18.5)s, maximum flow time was(6.7±3.9)s, postvoid residual urine was(29.9±21.5)ml, maximal detrusor pressure was(31.9±21.4)cmH 2O, bladder compliance was(78.1±33.9)ml/cmH 2O, normal desire to void was(258.2±185.5)ml, maximal capacity was(335.1±124.9)ml, maximum urethral pressure was(96.4±33.9)cm H 2O, maximum urethral closure pressure was(88.5±35.2)cmH 2O, and function urethral length was(37.2±7.2)mm.It can be seen that Qmax, Qave, voided volume, maximum detrusor pressure, bladder compliance, and functional urethral length in patients with abnormal urination are significantly lower after radical hysterectomy of cervical cancer than before the surgery.While, normal desire to void, maximum capacity, maximum flow time, and postvoid residual urine volume were higher after radical hysterectomy than before surgery( P<0.05). In addition, there was no significant difference in voiding time, maximum urethral pressure and maximum urethral closure pressure between pre-and post-operation.Besides, it is worth noting that there was no significant difference in preoperative urodynamic test results between patients without abnormal urination versus patients with abnormal urination( P>0.05), and the difference in urodynamic test results between the two groups is statistically significant( P<0.05). There was no statistically significant difference in abnormal urination and in urodynamic test results between different clinical stages and between different pathological types( P>0.05). Conclusions:The characteristics of urinary dynamics in patients with abnormal urination after radical hysterectomy of cervical cancer are mainly manifested as decreased bladder sensory function and abnormal detrusor function.And the urodynamic test can provide objective clinical indicators for early diagnosis.

Objective:To investigate the role of short-term use of mycophenolate mofetil (MMF) in EB viral infection and acute graft-versus host disease (GVHD) in patients receiving haploidentical hematopoietic stem cell transplantation (haplo-HSCT) .Method:Adult patients (≥14 years) who were diagnosed with hematological malignancies received haplo-HSCT in Peking University Institute of Hematology from May 2016 to December 2017 were retrospectively reviewed. The median age was 30 (14-60) years old. A total of 498 patients including 277 males and 221 females were enrolled. Donors' median age was 38 (8-66) years old. All patients were classified into long-term use of MMF ( n=199), which was defined as 500 mg every 12 hours from day 9 pre-transplant to 250 mg every 12 hours from day 30 after transplant then withdrawal on day 45 to 60 after transplant, and short-term use of MMF ( n=299), which was defined as 500 mg every 12 hour from day 9 pre-transplant then withdrawal till neutrophil engraftment. Kaplan-Meier model was used to analyze the cumulative incidence of EBV infection, and the Cox proportional regression model for multivariate analysis. Result:Characteristics including sex, age, disease types, mismatched HLA loci, donor-recipient relationship, donor-recipient blood type, donor age, and donor sex were comparable between two groups (all P＞0.05). According to once, the incidence of EBV viremia, defined as EBV＞10 3 copies/ml at least once, in short-term group and long-term group was 19.4% (58/299) and 27.6% (55/199) respectively ( P=0.046).Donor age and the duration of MMF prophylaxis (short-term group as reference) were associated with EBV viremia according to multivariate analysis [ HR=1.022(95% CI 1.006-1.038),1.600(95% CI 1.059-2.418); P=0.006 and 0.026, respectively]. The incidence of grade Ⅱ-Ⅳ and Ⅲ/Ⅳ acute GVHD in long-term and short-term group was 32.2% (64/199) versus 20.7% (62/299)( P=0.005) and 10.1% (20/199) versus 8.0% (24/299) ( P=0.427), respectively. Donor sex (female as reference) and duration of MMF prophylaxis (short-term group as reference) were associated with grade Ⅱ-Ⅳ acute GVHD [ HR=1.908(95% CI 1.079-3.373),1.752(95% CI 1.161-2.643); P=0.026 and 0.008, respectively].There were no statistical differences in the incidence of CMV viremia, refractory CMV viremia and hemorrhagic cystitis (all P＞0.05) between the two groups. Conclusion:Short-term use of MMF can reduce EBV viremia without increasing the development of acute GVHD in haplo-HSCT patients.
