Abstract
Arylpropionic ester scaffold was found as anti-inflammatory agents for the treatment and prevention of acute kidney injury (AKI). To further study the structure-activity relationship (SAR) of this scaffold, a series of acryl amides were designed, synthesized, and evaluated their anti-inflammation. Of these, compound 9d displayed the protective effect on renal tubular epithelial cells to significantly enhance the survival rate through inhibiting NF-κB phosphorylation and promoting cell proliferation in cisplatin-induced HK2 cells. Furthermore, 9d can interact with TLR4 to inhibit TLR4/STING/NF-κB pathway in the RAW264.7 cell. In vivo AKI mice model, 9d significantly downregulated the level of serum creatinine (Scr), blood urea nitrogen (BUN) and the inflammatory factors (IL-1β, IL-6, TNF-α) to improve kidney function. Morphological and KIM-1 analyses showed that 9d alleviated cisplatin-induced tubular damage. In a word, 9d was a promising lead compound for preventive and therapeutic of AKI.

Abstract
Fluoride anions (F-) play a crucial role in human physiological processes. However, excessive intake of F- would affect oxygen metabolism and promote the generation of oxygen-free radicals. Hence, it is essential to develop a precise and efficient fluorescent probe for visualizing F--induced oxidative stress. In this work, we developed the first bifunctional BODIPY-based fluorescent probe dfBDP with p-tert-butyldimethylsilanolate benzyl thioether as the sensing site for the detection of F- and HClO via two distinct reactions, the self-immolative removal and the thioether oxidation, which generate the sensing products with two nonoverlap fluorescence bands: 800-1200 and 500-750 nm, respectively. The probe dfBDP displays rapid response, high specificity, and sensitivity for the detection of F- (LOD, 316.2 nM) and HClO (LOD, 33.9 nM) in vitro. Cellular imaging reveals a correlation between F--induced oxidative stress and the upregulation of HClO. Finally, probe dfBDP was employed to detect F- and HClO in mice under the stimulation of F-. The experimental results display that the level of HClO elevates in the liver of mice.

Abstract
A dual functional BODIPY fluorescent probe was developed for simultaneous detection of H2O2 and viscosity, by collecting fluorescence from 800-1100 nm and 550-750 nm, respectively. Bioimaging based on the probe shows that H2O2 accumulates and cytoplasmic viscosity increases during the palmitic acid (PA)-induced pyroptosis process.

Abstract
Enterococcus faecium (E. faecium) is a clinical multidrug-resistant pathogen causing life-threatening infection, which makes it important to discover antibacterial agents with novel scaffolds and unique mechanism. In this study, the diarylurea scaffold was found to have potent antibacterial effect on E. faecium. Diarylurea ZJ-2 with benign drug-like property exhibited potent antibacterial and anti-biofilm activity through inhibiting the genes expression of NlpC/p60 hydrolase-secreted antigen A (sagA) and autolysins (atlA), down-regulating the expression of biofilm adherence related genes aggregation substance (agg), enterococcal surface protein (esp) against E. faecium. Moreover, ZJ-2 can be docked into SagA to inhibit daughter cell separation. In a mouse model of abdominal infection, ZJ-2 decreased the bacterial load and the level of IL-6 and TNF-α in a time-dependent manner. Overall, these findings indicated that diarylurea ZJ-2 has the potential to be developed as a therapeutic agent to treat drug-resistant enterococci and biofilm-related infections.

Abstract
Paraoxon (E600) was conjugated to bovine serum albumin(BSA) or tachypleus tridentatus hemocyanin (TTH) by diazotization. Two hybridoma cell lines secreting monoclonal antibodies(McAb) against paraoxon have been established by fusing mouse myeloma cells and splenocytes from Balb/c mice immunized with E600-BSA. The chromosomes of the hybridoma cell 2B10 were analyzed. The immunoglobulin of the McAb was classified. The affinity and specificity of this antibody were determined. The hybridoma cells have fairly reserved the antibody-producing capacity after continuously growing or stored in liquid nitrogen for 10 weeks.

Abstract
OBJECTIVE To reduce the incidence of urinary system injury from gynecology operations. METHODS 26 cases with urinary system injuries during gynecological operations were analyzed from 1982 to 1996. RESULTS The incidence of urinary injury in this hospital was 0.34%, and injuries occurred most frequently in the bladder. Among the 17 cases of bladder injuries, 12 occurred during tubal ligation, 3 during cesarean section, and 2 in myomectomy. There were 9 cases of ureter injuries, 6 cases occurred in radical hysterectomy for cervical cancer, 1 in cesarean section with hysterectomy, and 2 in hysterectomy with broad ligament leiomyoma. CONCLUSIONS This study demonstrated that it was important to be familiar with the regional anatomy, to operate strictly and separate those organs carefully in preventing the urinary system injury.

Abstract
This study included 168 patients with angina pectoris, who were divided into two groups, the diltiazem SR (No. 88) group and diltiazem HCL (No. 80) group. The two groups were comparable in age and duration of coronary heart disease. The results were as follows: (1) The total clinical effect of diltiazem SR (94.3%) was slightly greater than that of diltiazem HCL (82.5%), the effect in ECG improvement was 53.3% and 53.4% respectively. (2) The rate of adverse effect was 12.5% in diltiazem SR group and 14.4% in diltiazem HCL group. It is concluded that the two different types of diltiazem have similar effect in the treatment of angina pectoris. However, it is more convenient to take diltiazem SR than diltiazem HCL as the former needs only twice a day.
