ABSTRACT
Objective:To study the use of different assessment methods in predicting perioperative outcomes in patients with acute cholecystitis and decompensated cirrhosis.Methods:A retrospective study was performed on 28 patients with acute cholecystitis and decompensated cirrhosis (MELD ≥ 15) who underwent laparoscopic surgical intervention from January 2016 to August 2020 at the Third People Hospital of Xinjiang Uygur Autonomous Region. These patients were divided into 2 groups according to the severity of acute cholecystitis grading in the Tokyo Guidelines 2018 (TG18): TG18 grade Ⅰ for the mild cholecystitis group ( n=15) and TG18 grade Ⅱ and grade Ⅲ for the moderate and severe cholecystitis group ( n=13). 16 patients with a MELD score ranging from 5 to 15 and with TG18 grade Ⅰ were used as the control group. The operation-related conditions, surgical injuries and surgical complications were compared among the three groups. Results:Of 44 patients with acute cholecystitis and decompensated cirrhosis included in this study, there were 28 males and 16 females, aged (57.3±5.9) years. Significantly more patients in the moderate and severe cholecystitis group (13/13) suffered from cholecystitis due to stone impaction than the control group (11/16) and the mild cholecystitis group (10/15) ( P<0.05). When compared to the control group, patients in the mild cholecystitis group and the moderate and severe cholecystitis group had significant increases in operative time, intraoperative bleeding, amount of abdominal drainage, abdominal drainage time, delayed feeding time and hospital stay ( P<0.05). These perioperative outcomes were further and significantly increased in the moderate and severe cholecystitis group when compared to the mild cholecystitis group ( P<0.05). The blood bilirubin levels, blood creatinine levels and MELD scores after surgery were significantly better in both the mild cholecystitis group and the moderate and severe cholecystitis group on postoperative day 3 when compared to those before treatment ( P<0.05). The Child score was significantly better in the control group after surgery than that before surgery ( P<0.05). The grade Ⅰ-Ⅱ surgical complication rate was significantly higher in the moderate and severe cholecystitis group (11/13) than the mild cholecystitis group (5/15, χ 2=7.479), and the control group (4/16, χ 2=10.208) ( P<0.05). There were no significant differences in the grade Ⅲ-Ⅴ surgical complication rates among the three groups (all P>0.05). The overall surgical complication rate was significantly higher in the moderate and severe cholecystitis group (12/13) than the mild cholecystitis group (7/15, χ 2=7.385), and the control group (5/16, χ 2=11.023), (all P<0.05). Conclusions:The MELD score when combined with the severity grading for acute cholecystitis of the TG18 was effective to evaluate the perioperative risks of patients with acute cholecystitis and decompensated cirrhosis. Patients with a MELD score ≥ 15 and TG18 Ⅱ or Ⅲ had significantly higher risks after minimally invasive surgery.

ABSTRACT
The discovery and development of novel inhibitors with activity against variants of human immunodeficiency virus type 1 (HIV-1) is pivotal for overcoming treatment failure. As our ongoing work on research of anti-HIV-1 inhibitors, 32 N-arylsulfonyl-3-acylindole benzoyl hydrazone derivatives were prepared by introduction of the hydrazone fragments on the N-arylsulfonyl-3-acylindolyl skeleton and preliminarily screened in vitro as HIV-1 inhibitors for the first time. Among of all the reported analogues, eight compounds exhibited significant anti-HIV-1 activity, especially N-(3-nitro)phenylsulfonyl-3-acetylindole benzoyl hydrazone (18) and N-(3-nitro)phenylsulfonyl-3-acetyl-6-methylindole benzoyl hydrazone (23) displayed the most potent anti-HIV-1 activity with EC50 values of 0.26 and 0.31 µg/mL, and TI values of >769.23 and >645.16, respectively. It is noteworthy that introduction of R3 as the methyl group and R2 as the hydrogen group could result in more potent compounds. This suggested that introduction of R3 as the methyl group could be taken into account for further preparation of these kinds of compounds as anti-HIV-1 agents

As our ongoing work on research of anti-HIV-1 inhibitors, fifteen N-arylsulfonyl-3-formylindoles (3a-o) were designed and prepared through two step synthetic route. Firstly, 3-formylindoles (2a-c) were synthesized via the Vilsmeier-Haack reaction. Subsequently, treatment of 2a-c with the appropriate arylsulfonyl chlorides led to the corresponding target compounds in excellent yields. All analogues were also preliminary evaluated in vitro for their inhibitory activity against HIV-1 replication. Among of all the reported analogues, three compounds 3c, 3g and 3i displayed significant anti-HIV-1 activity, with EC50 values of 9.57, 11.04 and 5.02 µM, and TI values of 31.89, 13.79 and 81.69, respectively. N-m-nitrophenylsulfonyl-3-formylindole (3c) and N-m-nitrophenylsulfonyl-6-methyl-3-formylindole (3i) especially exhibited the best promising anti-HIV-1 activity. In addition, it demonstrated that insertion of a methyl group at the C-6 position of the indolyl ring and a nitro group at the meta position of the arylsulfonyl ring, as in compound 3i, resulted in both low cytotoxicity (CC50= 410.41 µM) and good antiviral activity

With the advent of Twenty-First century, more and more genome-wide association studies (GWAS) showed that idiosyncratic adverse drug reactions (ADRs) were closely related with human leukocyte antigen (HLA) alleles, such as the associations of abacavir-HLA-B*5701, allopurinol-HLA-B*5801, and carbamazepine-HLA-B*1502, etc. To explore the mechanisms of these idiosyncratic drug reactions, hapten hypothesis, danger signal hypothesis, pharmacological interaction (P-I) concept and autoimmune mechanism are proposed. In this paper, recent GWAS studies on the HLA-mediated adverse drug reactions and underlying mechanism are reviewed in detail.

ABSTRACT
The progress of research on the the anterior cruciate ligament (ACL) wound healing demonstrates that the synovial tissue in the knee joint plays a very important role in the healing process of injured ACL. Therefore, the molecular response mechanisms of lysyl oxidase (LOX) and matrix metalloproteina (MMP) in normal/injured ACL fibroblast cells could be considered to perform the major analysis function of injured ACL healing mechanism. The mRNA expressions of LOXs and MMPs and the activity expressions of MMP-2 in ACL fibroblasts co-cultured with synovial cells were analyzed by quantitative real-time PCR and zymography. The results showed that co-culture could regulate the mRNA expressions of LOXs and MMPs in the ACL fibroblasts cells. These results suggest that the differential expressions of LOXs and MMP-1, 2, 3 in co-cultured ACL indicate that interaction crosstalk do exist between ACL cells and synovial cells and provide a theoretical basis for subsequent exploration of the mechanisms and treatment of ACL injury and repair.

The molecular electronegativity-distance vector (MEDV) was used to describe the chemical structural characterization of 46 components of essential oils in the flower of Rosa banksiae. Various multiple linear regression (MLR) models were created with variable screening by the stepwise multiple regression technique and statistics. The QSRR models of 10 and 6 variables were built by MLR with the correlation coefficients (R) of molecular modeling being 0.906 and 0.903. Cross-validation of the models, which contain selected vectors were performed by leave-one -out procedure (LOO) and the satisfied results with correlation coefficients (Rcv) of 0.904 and 0.903, respectively. The results showed that the models constructed can provide estimation stability and favorable predictive ability.
