Objective To evaluate the protective effect of sinomenine (SIN) on renal ischemia/reperfusion (I/R) in mice. Methods In the experiment one, 12 C57BL/6 mice were randomly divided into 2 groups: SIN group (mice were injected with 200 mg/kg SIN by tail vein) and control group (mice were injected with equal volume of saline). Six and 24 hs later, the serum was collected and the contents of alanine aminotransferase (ALT) and creatinine (SCr) were determined. In the experiment two, C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, SIN group (mice were injected with 200 mg/kg sinomenine just before ischemia induction) and saline group (mice were injected with equal volume of saline at the same time). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The SCr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by using terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. The infiltration of F4/80 positive macrophages was measured by using immunohistochemistry and that of neutrophils with myeloperoxidase (MPO) kits. The mRNA expression of tumor necrosis factor (TNF)-α, chemokine CXC ligand (CXCL)-10, intercellular adhesion molecule (ICAM)-1 and IL-17 was detected by using real-time reverse transcription PCR. The activation of transcription factor NF-κB was measured by using Western blotting. Results In the experiment one, there was no significant difference in ALT and SCr between the two groups at 6 or 24 h. In the experiment two,levels of SCr and BUN were lower in SIN group (P＜0. 05 or P＜0. 01 ), histological damage was milder (P＜0. 01 ), and apoptosis rate of renal tubular epithelial cells apoptosis was lower than in saline group (P＜0. 05). The infiltration of macrophages, neutrophils and the mRNA expression of TNF-α, CXCL-10, ICAM-1 and IL-17 in the renal tissue in SIN group were reduced as compared with saline group (P＜0. 05 or P＜0. 01 ). The activation of NF-κB in SIN group was significantly downregulated as compared with saline group. Conclusion SIN can ameliorate the renal IR injury without hepatic or renal toxicity, which is associated with inhibition of acute inflammatory response induced by reperfusion.

This study was aimed to observe the regulating effect of Shen-Xiong Hua-Y u (SXHY) capsule precondi-tioning on the expression of subtypes of nitric oxide synthase (NOS), including endothelial nitric oxide synthase (eNOS), nervous nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS), in cerebral ischemia-reperfu-sion injury (CIRI) among rats, and to further clarify the mechanism of protective effect by SXHY capsule on acute CIRI rats. Rats were randomly divided into the sham operation group, CIRI group, and SXHY capsule of high-, medium-, and low-dose preconditioning group (480, 240, 120 mg·kg-1). Each group was further randomly divided into different subgroups, which were the 3, 6, 12, 24, 48, 72 h group after 2 h CIRI (n=6). Intragastric administration was given once a day for 7 days. The middle cerebral artery occlusion (MCAO) and reperfusion model was repro-duced by an intraluminal filament method on the 7th day. The protein expressions of eNOS, nNOS and iNOS were measured by immunhistochemical method. The results showed that compared with the sham operation group, expres-sions of eNOS, nNOS and iNOS in the CIRI group were increased at different time points (i.e., 3, 6, 12, 24, 48, 72 h, P< 0.05 or P< 0.01). Compared with the CIRI group, eNOS expression increased at different time points in SX-HY capsule group (P< 0.05 or P< 0.01). The nNOS and iNOS expression decreased at different time points (P<0.05 or P < 0.01). Among them, the high-dose group was the group with the most obvious effect. It was concluded that SXHY capsule preconditioning had protective effect on CIRI. Its mechanism may be related to the regulation on protein expression of NOS subtypes.

Objective To explore the effect of age on prognosis of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) complicated with diabetes mellitus (DM) after radical resection. Methods The clinical data of 250 patients with HBV-related HCC complicated with DM who received radical resection were collected from the First Affiliated Hospital of Nanchang University and the Eastern Hepatobiliary Surgery Hospital and were retrospectively analyzed. The patients aged 30-80 years old and were divided into the elder group (≥60 years n=58) and the non-elder group (<60 years, n=192). Propensity score matching (PSM) method was used for covariate balance and the overall survival (OS) rates were compared between the two groups. Cox regression was used to analyze the risk factors influencing the prognosis of HCC. Results In the PSM cohort (n=53 in elder group, n=85 in non-elder group), the 1-, 3-, 5-year OS rates were not significantly different between the two groups (P =0. 15). The results of Cox multivariate regression analysis revealed that age was not significantly associated with OS of patients with HBV-related HCC complicated with DM. Conclusion Elder age seems not to decrease the OS of patients with HBV-related HCC complicated with DM after radical resection; elder patients can obtain similar survival as the non-elder ones.

Objective To compare the prognoses of hepatocellular carcinoma (HCC) patientswho underwent anatomic liver resection (AR) or non-anatomic liver resection (NAR) using propensity score-matching methods. Methods We retrospectively analyzed the clinical data of 124 HCC patients who were treated in the First Affiliated Hospital of Nanchang University between Jan. 2010 and Dec. 2015. The patients included 64 undergoing AR (AR group), and 60 undergoing NAR (NAR group). Propensity score-matching methods were used to assess the overall survival (OS) of the patients in AR and NAR groups whle controlling the potential confounders, and the risk factors of prognosis of HCC patients were analyzed by Cox proportional hazardmodel. Results In the propensity score-matching cohort, the OS of the patients in AR group (n=29) was significantly longer than that in the NAR group (n=45) after propensity score-matching (52 [44. 83-59. 17] months vs 38 [31. 45-44. 55] months, P = 0. 005). The Cox proportional hazards model revealed that AR was associatedwith a superior OS (HR=0. 54, 95%CI 0. 30-0. 96, P =0. 04). Conclusion Propensity score-matching method has shown that AR can better improve the OS in HCC patients after liver resection compared withNAR.
