Objective To investigate the safety and efficacy of photoselective green laser vaporization of bladder tumor (PVBT). Methods A total of 522 patients with bladder tumor were enrolled in present study from January 2010 to May 2015, including 405 cases of non muscle-invasive bladder cancer (NMIBC) and 117 cases of muscle-invasive bladder cancer (MIBC). All of patients were treated with PVBT and intravesical instillation of epirubicin. Patients with MIBC received intravenous chemotherapy (kisi-hama and cisplatin). Results The hospitalization time was (7.32±1.28) days, the operation time was (27.08±5.36) min, and the indwelling urinary catheter was (2.42±0.34) days for patients in NMIBC group. During the follow-up period (12-60 months), 38 cases (9.4％) relapsed, of which 3 cases underwent radical cystectomy, and other 35 cases underwent PVBT again. All 405 patients were alive at the end of follow-ups. The hospitalization time was(26.18 ± 1.92) days, the operation time was (38.32 ± 6.54) min, and the time of indwelling urinary catheter was (2.72 ± 0.85) days for patients of MIBC group. During the follow-up period (12-60 months), 19 cases (16.2％) relapsed. Among them, 4 patients underwent radical cystectomy, and other 15 cases underwent PVBT. Six patients died from distant organ metastasis (including 2 cases of pulmonary metastasis and 4 cases of bone metastasis), and other 111 patients survived. Conclusion PVBT is safe and effective in the clinical application, especially for NMIBC and MIBC patients who are unable or unwilling to undergo radical cystectomy.

Water extract groups and amidazofen group with 10 in each group. All mice were intraperitoneally injected with 0.02 mL/g saline,0.10 and 0.15 mg/g polygonum bistorta L. Water extract solution and 0.10 mg/g amidazofen, respectively. Fifteen minutes later, mice were intraperitoneally injected with 6 g/L 0.01 mL/g acetic acid glacial to record times of twisting-body reaction within 15 minutes. ② Effect of polygonum bistorta L. Water extract on pain response of mice induced by hot-plate test: Forty female mice were randomly divided into 4 groups:saline group, 0.10 and 0.15 polygonum bistorta L. Water extract groups and morphine group with 10 in each group. All mice were intraperitoneally injected with 0.02 mL/g saline, 0.10 and 0.15 mg/g polygonum bistorta L. Water extract solution and 0.01 mg/g morphine solution, respectively. GJ-8402 hot-plate pain response threshold detector was used in this study; pain response temperature was (55.0±0.5) ℃; pain response after licking hindfoot was regarded as reactive marker; latency of pain response threshold was within 60 s. Pain response was measured at 15, 30 and 60 minutes after administration with hot-plate test. ③ Effect of morphine, naloxone and polygonum bistorta L. Water extract on pain response of mice induced by hot-plate test: Thirty female mice were randomly divided into 3 groups: saline group, naloxone+morphine group and naloxone+polygonum bistorta L. Water extract group with 10 in each group. All mice were intraperitoneally injected with 0.02 mL/g saline, 0.004 mg/g naloxone solution+0.01 mg/g morphine solution and 0.004 mg/g naloxone solution+0.15 mg/g polygonum bistorta L. Water extract solution, respectivelu. Pain response was measured at 15, 30 and 60 minutes after administration with hot-plate test. ④ Effect of polygonum bistorta L. Water extract on pain response of mice induced by electric stimulation: Forty mice were randomly divided into 4 groups with 10 in each group. All mice were intraperitoneally injected with 0.02 mL/g saline, 0.10 and 0.15 mg/g polygonum bistorta L. Water extract and 1 g/L morphine, respectively. Pain response was measured at 20, 35, 50 and 70 minutes after administration with electric stimulus method.MAIN OUTCOME MEASURES: ① Times of twisting-body reaction; ②duration of pain response induced by hot-plate test; ③ analgesic rate induced by electric stimulation.RESULTS: All 150 healthy adult Kunming mice were involved in the final analysis. ① Times of twisting-body reaction: At 15 inutes after administration, times of twisting-body reaction were less in 0.10 and 0.15 mg/g polygonum bistorta L. Water extract group and amidazofen group than those in saline group [(15.1±11.1), (8.0±6.5), (6.3±3.2), (54.1±20.2) times, t=3.532-3.681, P ＜ 0.01]. ② Duration of pain response induced by hot-plate test:At 15, 30 and 60 minutes after administration, durations of pain response induced by hot-plate test were longer in 0.10 and 0.15 mg/g polygonum bistorta L. Water extract group and morphine group than those in saline group (t=2.676-3.683, P ＜ 0.05-0.01). ③ Duration of pain response was longer in naloxone + polygonum bistorta L. Water extract group than that in saline group at each time point after administration (t=2.676-3.563, P＜ 0.05-0.01); however, duration in naloxone + morphine group was close to that in saline group (P ＞ 0.05). ④ Analgesic rate induced by electric stimulation: At 20, 35, 50 and 70 minutes after administration, analgesic rate induced by electric stimulation was higher in 0.10 and 0.15 mg/g polygonum bistorta L. Water extract group and morphine group than that in saline group (t=3.455-3.634, P ＜ 0.01).CONCLUSION: ① Polygonum bistorta L. Water extract has the obviously analgesic effect, whose intensity is close to that of amidazofen and morphine. ② Naloxone, an opiate receptor antagonist, can resist analgesic effect of morphine but not that of polygonum bistorta L. Water extract. This suggests that analgesic effect of polygonum bistorta L. Water extract dose not react through exciting opiate receptor.

Objective:To explore the efficacy and safety of five-step 180W XPS greenlight photoselective vaporization of prostate (PVP)for large volume (≥80ml) benign prostatic hyperplasia.Methods:A total of 240 BPH patients (PV≥ 80 ml), treated with five-step 180W XPS PVP from June 2017 to May 2019 in our center, were reviewed retrospectively. The average age was (70.18±7.71) years old, and 129 cases were over 70 years old. The average body mass index was (24.91±2.98 )kg/m 2. The median international prostate symptom score (IPSS) was 23 (20, 26) and the quality of life (QOL) score was 5 (4, 5) points. Besides, the preoperative median prostate volume (PV) was 98.29 (86.49, 116.32) ml, the median maximum urinary flow rate (Q max)was 6 (4, 8) ml/s and postvoid residual urine volume (PVR) was 120 (30, 200) ml. All patients underwent 180W XPS five-step method PVP operation according to the following method. The first step is vaporization of 1-2 o′clock (left lobe) and 10-11 o′clock (right lobe) in order to establish operating channel. The second step is vaporization of the lateral lobe layer by layer from the ventral side to the dorsal side. The third step is channel establishment of 5/7 o′clock mid lobe parasulcus. The forth step is ablation of the middle lobe laterally. The fifth step is vaporization of the apex of the prostate and trimming. The IPSS score, QOL score, Q max and PVR were evaluated 12 months later after the PVP operation. Results:All the 240 cases were treated by five-step 180W XPS PVP operation successfully. The median operation time and laser time were 83 (73, 98.75) min and 66 (60, 76) min. Capsular perforation was found in 3 cases, which occurred in the trimming stage. There were 9 cases treated with TURP to stop bleeding, and no cases suffered blood transfusion. Twenty-two patients underwent bladder irrigation for 6 to 24 hours after the operation, and the median catheter indwelling time and post-operative hospital stay were 3 (3, 4) days and 4 (3, 5) days respectively. Twenty-six patients suffered urinary incontinence, including 22 cases of urinary incontinence and 4 cases of stress urinary incontinence. In addition, there was no severe hematuria, severe bladder irritation or urinary retention among the patients. The postoperative IPSS score was 5(4, 7), QOL score 1(1, 2), Q max 18(15, 20)ml/s and PVR 10(0, 30)ml, which were all significantly improved compared with those before surgery ( P<0.01). None second PVP surgery was performed. Conclusions:The five-step 180W XPS PVP operation has the advantages of improving lower urinary tract symptoms, less blood loss and low incidence of perioperative adverse events. It is easy to use, which is a reliable minimally surgery.

Anticoagulant pharmacists performed the pharmaceutical care for one child with warfarin resistance by detecting the relevant genes and retrieving the literatures. The reasons for warfarin resistance were analyzed, and the anticoagulation characteristics during menstrual period were explored in order to provide a reasonable anticoagulant recommendation for the child. Anticoagulant pharmacists defined the cause of warfarin resistance was gene polymorphism, and then implemented an individualized anticoagulant treatment according to the situation of the child. After the discharge of the patient, pharmacists carried out long -term follow -up to make the INR within the target range. Anticoagulant pharmacists should perform the whole course anticoagulation management during hospitalization and after discharge, and provide specific pharmaceutical services respectively for doctors and patients in order to guarantee the effectiveness and safety of anticoagulation and reflect the career value of pharmacists.

Objective To evaluate the clinical efficacy and safety of short-segment pedicle screw fixation combined with vertebroplasty for the treatment of thoracolumbar osteoporotic compression fractures.Methods A retrospective case control study was conducted on 63 patients with fresh thoracic or lumbar osteoporotie compression fractures who were surgically treated from January 2010 to December 2013.There were 26 males and 37 females,with age of 63-87 years [(76.3 ± 5.7) years].According to the surgical method,the patients were assigned to simple vertebroplasty group (Group A),short-segment pedicle screw fixation group (Group B),and short-segment pedicle screw fixation group combined with vertebroplasty group (Group C),with 21 cases in each group.Length of hospital stay,operation time,and blood loss were recorded.The visual analog scale (VAS),anterior vertebral body height,angle of the kyphotic deformity,and complications before operation,immediately after operation,3 months after operation,and at the last follow up were compared among three groups.Complications of each group were recorded.Results The hospital stay,operation time,and blood loss in Group C were significantly higher than those in Group A (P ＜ 0.05),but there were no significant differences between Group B and Group C (P ＞ 0.05),except for a longer operation time in Group C.The pre-operative VAS showed no significant difference among three groups (P ＞ 0.05).However,the mean VAS in Groups A,B and C at the last follow up were 1.0(0.0,2.0)points,1.0(0.0,2.0)points,0.0(0.0,1.0)points,respectively.The VAS in Group C was significantly lower than that in Group B or A (P ＜ 0.05).The mean anterior vertebral body height and angle of the kyphotic deformity in Group C had no significant difference from that in Group A or B before operation and immediately after operation (P ＞ 0.05).At the last follow up,the mean anterior vertebral body height and angle of the kyphotic deformity in Groups A,B and C were (68 ±14.7)％,(72.3 ±9.0)％,(81.5 ±5.6)％ and (10.6 ±3.9)°,(10.7 ±5.0)°,(7.4 ± 5.0) °,respectively.The loss of anterior vertebral body height and angle of the kyphotic deformity correction in Group C were significantly less than that in Group A or B (P ＜ 0.05).Superficial infection was found in Groups B (n =2) and C (n =1),and the infection was cured after antibiotic therapy and dress change.Bone cement leakage was found in Groups A (n =8) and C (n =5),with no nerve compression.Internal fixation failure was seen in Group B (n =3),and the implant was removed directly.Conclusion Short-segment pedicle screw fixation combined with vertebroplasty can effectively reduce the loss of anterior vertebral body height and angle of the kyphotic deformity and hence enhance the clinical efficacy.
