ObjectiveTo explore the effect and mechanism of Taishan Panshi powder （TSPSP） on inhibiting oxidative stress injury in human chorionic trophoblast cells （HTR-8/SVneo）， and to uelucidate the underlying mechanism of TSPSP in the treatment of spontaneous abortion （SA）. MethodsGene differential analysis of SA was performed using the Gene Expression Omnibus （GEO） database and correlated with oxidative stress. Network pharmacology was employed to screen the active components of TSPSP， and a "Chinese medicine-component-target-disease" network was constructed to predict the mechanism of action of TSPSP. For in vitro validation experiments， HTR-8/SVneo cells were divided into blank group， model group， TSPSP-containing serum 2.5%， 5%， 10% groups， and nuclear factor E₂-related factor 2 （Nrf2） inhibitor group （ML385， 30 μmol·L^-1）. Except for the blank group， other groups were stimulated with 150 μmol·L^-1 H₂O₂ for 3 h to establish a cell oxidative stress injury model. After successful modeling， the blank group and model group were given 10% blank serum， each TSPSP-containing serum group was treated with the corresponding concentration of drug-containing serum， and the Nrf2 inhibitor group was additionally given 30 μmol·L^-1 ML385 on the basis of 10% TSPSP-containing serum. All groups of cells were continuously cultured under the above conditions for 24 h， and then samples were collected for subsequent detection. Cell viability in each group was detected by CCK-8 assay. Cell migration rate was detected by scratch test. The contents of malondialdehyde （MDA）， Fe²⁺， and Glutathione （GSH） were detected by enzyme-linked immunosorbent assay （ELISA）. Intracellular reactive oxygen species （ROS） level was detected by a fluorescent probe （DCF-DA）. The protein and mRNA expression levels of Kelch-like ECH-associated protein 1 （KEAP1）， Nrf2， and forkhead box protein O3 （FoxO3） in cells were detected by immunofluorescence （IF） and real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of KEAP1， Nrf2， FoxO3， Glutathione peroxidase 4 （GPX4）， and superoxide dismutase （SOD） in cells were detected by Western blot. ResultsThe GSE76862 and GSE22490 datasets were obtained from the GEO database. Differential gene analyses showed that the KEAP1， Nrf2， and FoxO3 genes were all associated with the disease. After matching with the oxidative stress pathway， nine significantly differential pathways were identified （P<0.05）， among which three contained the target genes Nrf2 and FoxO3. A total of 246 active ingredient targets of TSPSP and 2 804 SA-related targets were obtained through network pharmacology， and 154 potential action targets were obtained after taking the intersection. Topological analysis showed that targets such as KEAP1 and Nrf2 exhibited high degree values. GO and KEGG enrichment analyses indicated that the intersection targets were mainly involved in oxidative stress response， FOXO and MAPK signaling pathways， etc. In in vitro experiments， compared with the blank group， the cell viability in the model group was significantly decreased （P<0.01）. Compared with the model group， the cell viability in each TSPSP-containing serum group was significantly increased （P<0.01）. Compared with the 10% TSPSP-containing serum group， the cell viability in the ML385 group decreased to approximately 70% （P<0.01）. Compared with the blank group， the model group showed significantly increased contents of MDA， Fe²⁺， and ROS， decreased GSH expression （P<0.01）， significantly reduced cell migration rate （P<0.01）， and increased protein and mRNA expression levels of KEAP1 and FoxO3 （P<0.01）， while decreased protein and mRNA expression levels of Nrf2， GPX4， and SOD （P<0.01）. Compared with the model group， each TSPSP-containing serum group showed significantly decreased contents of MDA， Fe²⁺， and ROS， increased GSH expression （P<0.01）， significantly increased migration rate （P<0.01）， significantly decreased protein and mRNA expression levels of KEAP1 and FoxO3 （P<0.05， P<0.01）， and significantly increased protein and mRNA expression levels of Nrf2， GPX4， and SOD （P<0.05， P<0.01）. Compared with the 10% TSPSP-containing serum group， the ML385 group showed reversed trends in all indicators （P<0.05， P<0.01）. ConclusionTSPSP can inhibit H₂O₂-induced oxidative stress injury of trophoblast cells， and its mechanism of action may be related to the drug activating the KEAP1/Nrf2/FoxO3 signaling pathway.

OBJECTIVE： To study the efficacy and economics of cefoperazone/sulbactam combined with moxifloxacin and amikacin versus cefoperazone/sulbactam combined with tigecycline in the treatment of pneumonia with multidrug-resistant Acinetobacter baumannii （MDRAB）. METHODS： By prospective study， 150 MDRAB pneumonia patients were selected from Jingmen Second People’s Hospital during Jan. 1st， 2016-Aug. 31st， 2019， and then randomly divided into control group and observation group， with 75 cases in each group. Control group was given Cefoperazone/sulbactam sodium for injection （3 g， q8 h， ivgtt） combined with Tigecycline for injection （first dose 100 mg， maintenance dose 50 mg， q12 h， ivgtt）. Observation group  was give Cefoperazone/sulbactam sodium for injection （3 g， q8 h， ivgtt） combined with Moxifloxacin hydrochloride and sodium chloride injection （400 mg， qd， ivgtt） and Amikacin sulfate injection （0.6 g， qd， ivgtt）. The treatment lasted for 14 days in both groups. The time for body temperature to return to normal， lung rales disappearance， WBC to return to normal and PCT to return to normal， clinical efficacy， bacterial clearance rate and the occurrence of ADR were compared between 2 groups. Cost-effectiveness analysis was used to evaluate the cost- effectiveness ratio （C/E） and incremental cost-effectiveness ratio （ΔC/ΔE） of 2 groups using antibiotics cost as cost. Sensitivity analysis was performed by reducing drug cost by 15％. RESULTS： There was no statistical significance in the time for body temperature to return to normal， lung rales disappearance， WBC to return to normal and PCT to return to normal between control group and observation group （P＞0.05）. Clinical response rates of 2 groups were 85.33％ and 81.33％， and bacterial clearance rate were 89.33％ and 82.67％， with statistical significance （P＞0.05）. No serious ADR occurred in either group. The antibacterial cost of control group and observation group were 32 371.49 yuan/person and 9 367.82 yuan/person. C/E of clinical response rate were 379.37 and 115.18， and C/E of bacterial clearance rate were 362.38 and 113.32 in 2 groups， respectively. ΔC/ΔE of clinical response rate and bacterial clearance rate between control group and observation group were 5 750.92 and 3 454.00. Sensitivity analysis supported cost-effectiveness analysis results. CONCLUSIONS： Cefoperazone/sulbactam combined with moxifloxacin and amikacin versus cefoperazone/sulbactam combined with tigecycline in the treatment of pneumonia with MDRAB has similar efficacy， but cefoperazone/sulbactam combined with moxifloxacin and amikacin has economic and social benefits.

Objective To explore the efficacy of postoperative adjuvant transarterial chemoembolization (TACE) on the survival of patients after radical resection for hepatocellular carcinoma (HCC).Methods Between March 2007 and March 2010,229 HCC patients who underwent radical resection were retrospectively studied.Patients who underwent resection alone were used as the control group (138 patients) while those who received post-operative adjuvant TACE was used as the interventional group.In order to balance the covariates between the groups,a matched comparison of the patients was done by selecting patients using the propensity score matching (PSM).Then,the efficacy of adjuvant TACE upon survival was evaluated.Results After PSM,we obtained 67 pairs of patients.The survival time for the interventional and the control groups were 32.1 months and 28.3 months respectively.The survival rates at year 1,2,3 post-resection were 94.0％,84.8％ and 75.3％ in the interventional group versus 83.6％,69.9％ and 61.5％ in the control group respectively.There were no significant differences between the two groups (P =0.062).Univariate analysis showed the serum level of AFP,tumor size,number of tumor,BCLC stage,and adjuvant TACE significantly affected the survival of HCC patients who received radical resection (P ＜0.05).Cox model suggested that AFP≥400 μg/L and tumor diameter ＞ 5 cm were independent risk factors of survival for HCC patients who received radical resection (P ＜ 0.05).Conclusion Postoperative adjuvant TACE had no positive effect on survival,and AFP level ≥ 400 μg/L and tumor size ＞5 cm were independent risk factors of survival of HCC patients who received radical resection.

Objective: The effect of thymosin alpha 1 (Tα1) on patients with hepatocellular carcinoma (HCC) after radical hepatectomy was assessed. Methods: A total of 558 HCC patients treated by radical hepatectomy were retrospectively collected. Patients in the treatment group (n=146) received postoperative Tα1 therapy, whereas patients in the control group (n=412) did not. Propensity scale matching was conducted to improve the balance between the two groups. Changes in liver function, recurrence-free survival rates, and overall survival rates were compared between the two groups. Results: Postoperative liver function (i.e., TBIL, ALB, ALT, and PT) in the treatment group was significantly better than that in the control group (P<0.05). The one-, two-, and three-year recurrence-free survival rates and overall survival rates in the treatment group were significantly higher than those in the control group (P=0.019 and P=0.011, respectively). Conclusion:Postoperative Tα1 therapy can improve postoperative liver function, thus significantly prolonging recurrence-free survival and overall survival.
