The change of lung lymph after endotoxin-induced lung injury was studied using a sheep model with chronic lung lymph fistula. After endotoxin injection Ppa、PMV、 Q_L、CL_p、L_A/P_A、and Kf all increased markedly. The ratios of effects of pressure and permeability on Q_L were 1:0.53 and 1:2.31 during phase I and phase H respectively. The results indicated that the formation of pulmonary edema after injury related mainly to the increases of PMV and Kf and to the decrease of effective colloid osmotic pressure. The PMV was the main factor of formating edema during phase I and the permeability was that during phase Ⅱ.

We observed the pulmonary responses and changes in TXB2 and 6-keto-PGF1a concentrations in plasma and lung lymph in endotoxin induced lung injury. The typical pulmonary responses appeared after the injury. The TXB2 concentrations in plasma and lung lymph increased by 24.5 and 30.7 times and those of 6-keto-PGFla by 10.6 and 15.7 times, respectively, as compared with baseline. The TXB2 and 6-keto-PGF1a concentrations in lymph were 68 and 75 percent higher than those in plasm a respectively. The results indicated that TXA2 and-PGI2 synthesis increased in the lung after injury and that TXA2 and PGI2 were important media in the lung injury.

Objective:To analyse the evaluation and experience of clinical effect of minimally invasive drainage and craniotomy in the treatment of patient with epidural hematoa.Methods:100 cases of patients who were diagnosed as epidural hematoma from January 2015 to January 2016 were selected and randomly divided into two groups,where the control group were given craniotomy,and the observation group were given minimal invasive drainage.The effect of the surgery and the life qualities before and after treatment of the two groups were compared.Results:The effect of observation group is better than that of control group (P ＜ 0.05);craniocerebral defect and the re-hemorrhage incidence occurrence in the observation group were obviously lower than those in the control group,(0 ％,6 ％ vs 12 ％,20 ％) (P＜0.05).Conclusion:Compared with craniotomy,minimal invasive drainage in clinical treatment of epidural hematoma showed advantage in at smaller trauma,faster recovery,and better effect,thus deserving further promotion of clinic application.

Objective To observe the effect of saikosaponin-d on transcriptional activation of estrogen receptor in rat hepatic stellate cells(HSC-T6), and to explore its pharmacological mechanism. Methods The rat HSC-T6 were cultured in vitro for the study. After transient transfection of HSC-T6 with the ER-specific reporter gene ERE-tk-Luc by liposome, the effect of saikosaponin-d and estradiol on luciferase activity was observed by Dual-Luciferase Reporter Assay System under the conditions of various drug concentrations, various treatment time and addition of estrogen receptor inhibitor ICI182. 780. Results When the concentrations of saikosaponin-d and estradiol were in the range of 0.01-5 μmol/L, 0.01-1 μmol/L respectively, luciferase activity was increased in a dose-dependent manner . Luciferase activity arrived the highest when saikosaponin-d concentration was 5 μmol/L and estradiol concentration was 1 μmol/L, but the effect was weakening when estradiol concentration reached 5μmol/L. In respect of the effect of treatment time, when HSC-T6 were separately treated with 5μmol/L of saikosaponin-d and 1 μmol/L of estradiol for 24 h, the luciferase activity was the highest. And ICI182.780 could significantly inhibit the induction of saikosaponin-d and estradiol for luciferase activity. Conclusion Saikosaponin-d has an effect on promoting the transcriptional activation of estrogen receptor in HSC-T6.

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.
