This study is to screen the Chinese herbal compounds which could inhibit the production of Abeta and investigate the underlying mechanism. Ten types of compounds which have potential value in the treatment of AD were selected as initial screening trial. The cell models which used could overexpress Abeta and beta-secretases or Abeta and gamma-secretases. Extracellular Abeta was determined by ELISA after the cell models treated with different concentrations of compounds (0.5-100 micromol x L(-1)), separately. Then the compounds were selected which could inhibit extracellular Abeta and their best concentration ranges were decided, too. Furthermore, the cell viability and apoptosis rate, the level of intracellular Abeta, beta and gamma-secretases were determined after the cell models treated with different concentrations of selected compounds. The results showed that 4 of the 10 compounds could reduce the level of extracellular Abeta; they were cryptotanshinone, astragalosides, gastrodin and paeoniflorin, and their best concentration ranges were 0.5-5.0, 0.5-5.0, 5.0-50, 1.0-25 micromol x L(-1), respectively. Further study indicated that the 4 selected compounds were nontoxic to the cellular models and lowering intracellular Abeta were more effective compared with extracellular; of which astragalosides and gastrodin showed dose-dependent inhibition to the activities of beta and gamma-secretases, with the maximum inhibiting rates of 78.2% and 80.3%, respectively. In conclusion, cryptotanshinone, astragalosides, gastrodin and paeoniflorin could inhibit the expression and secretion of Abeta, and the underlying inhibiting mechanism of astragalosides and gastrodin were related with the reduction of the beta and gamma-secretase activities, respectively.

Objective To discussed application effect of modified flowchart of preoperational articles in the operating room. Methods A group for the reconstructed flowchart was set up to look into the problems of traditional flowchart for articles preparation and then have the flowchart modified upon the found problems. The duration for article preparation and the flaw rate were compared between pre-and post-modification. Result The duration for preparation after modification was significantly shorter than that before modification and the flaw rate was significantly lower as well (P<0.001). Conclusion The modified flowchart for article preparation in the operation room can reduce the flaw rate and shorten the duration for article preparation, thus ensuring smooth operation.

Objective To study the correlation between the dynamic changes of sex hormones and the severity and prognosis of head injury,and to investigate the role of sex hormones in traumatic brain injury.Methods The dynamic changes of sex hormones were quantitatively dynamic measured in 100 patients with head injuries,while the relationships between glasgow coma score(GCS),glasgow outcome score(GOS) and the concentration of sex hormones were also studied.Results The estradioi,progesterone and testosterone levels in serum increased within 12 hours after trauma in all groups.Estradiol increased markedly continuously within 1,3 days in GCS≤12 group,testosterone levels in serum decreased within 3 days after trauma in GCS=3～8 group,with a significant differnce compared with others groups.The concentration of sex hormones correlated positively with GOS.Conclusions The measurement of sex hormones may be useful to judge the severity and prognosis of head injury in earlystage.The increases of estradiol in the early stage after traumatic brain injury may exert powerful protective effects on brain tissues.Decreases of sex hormones are important factors leading to death of patients of traumatic brain injury.

Objective To investigate the safety and efficacy of the modified laparoscopic radical cystectomy and standard pelvic lymph node dissection for female bladder cancer patients.Methods Fortyone female patients with bladder cancer who underwent laparoscopic radical cystectomy(LRC) and standard pelvic lymph node dissection(sPLND) in our hospital from June 2003 to January 2016 were retrospectively analyzed.The patients were divided into two groups according to the surgical procedure.There were 15 patients with ≤ cT2 tumor and 1 patient with cT3 in the modified group.The average age was (62.2 ± 11.5) years.The median BMI was 20.7 kg/m2,ranging 18.4 to 22.2 kg/m2;The ASA level was less than Ⅱ in 9 (56.2％) cases and was level Ⅲ in 7 (43.8％) cases.There were 22 patients with ≤ cT2 tumor and 3 patients with cT3 in the traditional group.The average age was (60.4 ± 12.9)years.The median BMI was 21.7 kg/m2,ranging 18.4 to 23.1 kg/m2.ASA was less than level Ⅱ in 15(60.0％) cases and level Ⅲ in 10(40.0％) cases.All operations are performed under general anesthesia.In the traditional group,the plane between rectus and uterus is separated first.Then open the posterior cervical fornix and cut off the lateral bladder pedicle,cardinal ligament of uterus and urethra.The bladder and uterus are removed together.The sPLND is performed at last.In the modified group,the sPLND is performed first.Then separate the bladder and uterus until the anterior wall of the vagina can be exposed.The bladder and uterus are removed separately.Data of the operation and the complications were collected and analyzed.Results All patients were performed the operation successfully.No open conversion was recorded during the operation.No patient died during the peripheral operative phase.In modified group,10 patients received orthotopic ileal neobladder (OIN),5 patients received ileal conduit and 1 patient received ureterostomy.In traditional group,19 patients received OIN,3 patients received ileal conduit and 3 patients received ureterostomy.No significant difference of surgical method was noticed in those group.The median operative time in modified group and traditional group was 290 min (ranging 265-335 min) and 315 min (ranging 270-380 min),respectively(P ＞ 0.05).The median estimated blood loss in modified group and traditional group was 100ml (100,100) and 200ml (200,400),respectively (P ＜ 0.05).The rate of transfusion in modified group and traditional group was 6.3％ (1/16) and 18.5％ (5/27),respectively (P ＜0.05).The incidence of early complications between two groups showed no statistically difference.No major (Clavien grade 3 to 5) complications occurred in modified group.However major complications occurred in 3 patients in traditional group,followed by 2 neobladder vagina fistula,1 ileal anastomotic stoma fistula.All those complications were cured by operation.All patients were diagnosed urothelium carcinoma.In modified group,the tumor stage included carcinoma in suit in 2 cases,pTa-pT1 in 7 cases,pT2 in 6 cases,pT3 in one case.In traditional group,the tumor stage included pT1 in 12 cases,pT2 in 10 cases,pT3 in 3 cases.The numbers of resected lymph node in modified group and conventional group were 16 (ranging 7-19) and 10 (ranging 7-13),respectively (P ＞ 0.05).Conclusions The modified laparoscopic radical cystectomy and pelvic lymph node dissection for female bladder cancer patients could reduce the blood loss and incidence of neobladder vaginal fistula comparing with the traditional operation.

OBJECTIVETo investigate the clinical application of diffusion weighted imaging (DWI) in uterine cervical cancer and the apparent diffusion coefficient (ADC) value in diagnosis and predicting treatment response.

METHODSTwenty-eight patients with advanced primary cervical cancer confirmed by pathology and 10 cases of normal uterine cervix as control were recruited in this prospective clinical trial. To analyze the correlation between tumor volume measured in DWI and tumor maximum diameter measured according to the RECIST criteria. To compare the ADC value differences among the uterine cervical cancer, uterine myometrium, and normal uterine cervix. To compare the ADC values in 17 cancer patients before and after treatment.

RESULTSThe illustration of tumor boundary in DWI was superior to conventional T2WI and post-enhancement T1WI. The DWI with higher b value (2000 s/mm(2)) had a better signal-to-noise ratio. The tumor volume measured in DWI has good correlation with tumor maximum diameter according to RECIST criteria (r = 0.759, P < 0.01). When b = 800 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium, and normal uterine cervix were (9.85 ± 1.55)×10(-3) mm(2)/s, (14.20 ± 2.80)×10(-3) mm(2)/s, and (14.14 ± 0.45) ×10(-3) mm(2)/s. When b = 2000 s/mm(2), the ADC values of the uterine cervical cancer, uterine myometrium and normal uterine cervix were (7.38 ± 0.98)×10(-3) mm(2)/s, (8.52 ± 2.38)×10(-3) mm(2)/s, and (8.60 ± 0.63)×10(-3) mm(2)/s, respectively. There were significant differences between the cervical cancer and normal cervix or uterine myometrium (P < 0.001 for both). When b = 800 s/mm(2), the ADC value was (9.85 ± 1.55)×110(-3) mm(2)/s before and (13.41 ± 2.93)×10(-3) mm(2)/s after treatment (P < 0.001). When b = 2000 s/mm(2), the ADC value was (7.38 ± 0.98)×10(-3) mm(2)/s before and (8.93 ± 1.92)×10(-3) mm(2)/s after treatment (P = 0.008). Univariate logistic regression analysis showed that 25% ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were significantly correlated to the treatment outcome of cervical cancer (P < 0.05 for all). Multivariate regression analysis showed that 25%ADC, 50%ADC, and 75%ADC in the tumor ADC value histogram before treatment were not significantly correlated to the treatment outcome of cervical cancer (P > 0.05 for all). The values of ROC curves were 25%ADC = 0.818, 50%ADC = 0.775, and 75%ADC = 0.716 (P > 0.05), however, the 25% ADC showed a relatively stronger statistical power.

CONCLUSIONSDWI helps to confirm the morphology and exact target zone of the tumor for radiotherapy. DWI volume measurement is well correlated with RECIST criteria, particularly in volume measurement of irregular tumors. ADC value has a potential in quantitatively monitoring treatment response and predicting outcome of cervical cancers.

Acute respiratory distress syndrome (ARDS) is considered to be a pulmonary manifestation of systemic inflammatory response syndrome (SIRS), often occurring as a complication of disease, and worsening the prognosis of patients. In recent years, the incidence of trauma has increased year by year. Severe trauma can lead to SIRS, which is one of the common risk factors of ARDS. The spleen is the largest peripheral immune organ of the body, containing a large number of immune cells and secreting inflammatory factors. The inflammatory factors play an important role in the formation of traumatic ARDS. In recent years, the benefits of treating ARDS by inhibiting spleen-induced inflammatory response have gradually been discovered, providing new ideas for the treatment of ARDS. Therefore, the research status of spleen-mediated inflammatory response in traumatic ARDS is of great significance for the prevention and treatment of traumatic ARDS. This article reports the spleen-mediated systemic inflammatory response, the role of inflammatory mediators in the development of ARDS, and the current state of research on ARDS treatment to explore new approaches to the prevention and treatment of traumatic ARDS.
